Description

Vehicle sunroof structure

The present invention relates to a vehicle sunroof structure including a sunroof portion provided on a roof of a vehicle, and a first frame member and a second frame member provided to intersect the roof.

Various vehicle sunroof structures related to this have been proposed. For example, the vehicle roof frame structure described in JP-A-2012-40999 includes a square sunroof unit (sunroof portion) in top view and roof side rails (first frame) extending in the longitudinal direction at both ends in the vehicle width direction. member). The sunroof unit is coupled to each roof side rail by brackets provided at the four corners of the sunroof unit. In a panel support mechanism for a sunroof device disclosed in Japanese Patent Laid-Open No. 2004-161104, a substantially rectangular inner frame that supports the sunroof panel is arranged on the lower surface of the roof panel via a bracket provided on the front side thereof. It is fixed to a roof reinforcement (second frame member) provided and extending in the vehicle width direction.

By the way, in the above configuration, from the viewpoint of ensuring the NV performance (quietness, etc.) of the vehicle, it is desirable that the sunroof section is configured so as not to easily resonate with the vibration of the vehicle body. That is, the vibrations transmitted from the road surface and the vibrations of the engine, etc. during running are transmitted to the sunroof portion through the pillars that constitute the vehicle body. At this time, the sunroof section, which resonates with the vibration of the vehicle body, shakes so as to vibrate the surrounding roof panel, which may generate unintended noise (abnormal noise such as muffled noise). Although it is conceivable to additionally install a mass damper on the sunroof to suppress resonance, this would inevitably increase the weight of the vehicle. SUMMARY OF THE INVENTION The present invention has been devised in view of the above points, and an object of the present invention is to suppress resonance of the sunroof portion while suppressing an increase in the weight of the vehicle.

As a means for solving the above problems, a vehicle sunroof structure of the first invention comprises: a sunroof portion provided on a roof of a vehicle; a first frame member extending in the longitudinal direction of the roof; and a second skeleton member extending in the cross direction of the In this type of configuration, it is desirable to suppress resonance of the sunroof portion while suppressing an increase in the weight of the vehicle. Therefore, in the sunroof structure of the present invention, the axial connecting member that connects the sunroof portion to either the first frame member or the second frame member on the imaginary axis passing through the center of gravity of the sunroof portion and the position different from the axial connecting member. A connecting member for connecting the sunroof portion to either the first frame member or the second frame member is provided. In the present invention, by adjusting the rigidity of the connecting member, it is possible to swing the side of the sunroof portion on which the connecting member is not provided with the axial connecting member as a fulcrum so as to suppress resonance. . In the sunroof structure of the present invention, since resonance is suppressed by vibration of the sunroof portion, there is no need to separately set a mass damper, and an increase in the weight of the vehicle can be suppressed as much as possible.

The vehicle sunroof structure of the second invention is the vehicle sunroof structure of the first invention, wherein the sunroof part is separated from another imaginary axis line passing through the center of gravity of the sunroof part so as to intersect the imaginary axis line with the plan view of the roof as a reference. are divided into one side and the other side, the connecting member includes the intersection point between the sunroof portion and the other imaginary axis line, the point located on one side of the intersection point, and the point located on the other side of the intersection point. is provided in at least one location of In the present invention, by providing a plurality of or a single connecting member at a desired position with reference to another imaginary axis, it is possible to swing the side of the sunroof portion on which the connecting member is not provided more reliably.

A vehicle sunroof structure according to a third aspect of the invention is the vehicle sunroof structure of the first aspect or the second aspect, wherein the connection member is provided only on one side of the roof spaced apart from the virtual axis and The other side, which is located on the opposite side and is not provided with the connecting member, is fixed to the first skeleton member or the second skeleton member. In the present invention, the other side of the vehicle sunroof structure, which is not provided with a connecting member, is fixed and reinforced to the first frame member or the second frame member.

A vehicle sunroof structure of a fourth invention is the vehicle sunroof structure of any one of the first to third inventions, wherein the axial connection member has higher rigidity than the connection member. In the present invention, by increasing the rigidity of the shaft-mounted connecting member, which serves as a fulcrum, the side of the sunroof on which the connecting member is not provided is allowed to sway while ensuring the mountability (supportability) of the sunroof more reliably. can be made easier.

According to the first aspect of the present invention, it is possible to suppress resonance of the sunroof portion while suppressing an increase in the weight of the vehicle. Further, according to the second invention, the resonance of the sunroof portion can be suppressed more reliably. Further, according to the third invention, the configuration contributes to ensuring the mountability to the roof. Further, according to the fourth invention, it is possible to more reliably suppress resonance of the sunroof part while ensuring the mountability of the sunroof part.

5a and 5b that extend in the front-rear direction on both sides in the vehicle width direction, and a plurality of roof reinforcements 6 to 10 that extend in the vehicle width direction. is provided. The roof panel 4 gently curves upward toward the rear, and both edges in the vehicle width direction are fixed to

roof side rails

5a and 5b. Further, the

roof side rails

5a and 5b are supported by pillars (12, 13, 14), which are pillars in the front, rear, left, right, and central portions of the vehicle body 11 (for convenience, only the pillars on the left side of the vehicle are shown in FIG. 1). do). Here, as shown in FIG. 4, each roof side rail 5a and the like is formed to have a hollow closed cross section by fixing an inner panel 51 and an outer panel 52 with left and

right flanges

53 and 54, respectively. An end portion (right end portion in the drawing) of the roof panel 4 in the vehicle width direction is overlapped and fixed to a flange 54 on the inside of the vehicle (left end in FIG. 4) of each roof side rail 5a.

A plurality of roof reinforcements 6 to 10 shown in FIGS. 1 and 2 are beam-like structures that support the roof panel 4 from below, and are bridged between the left and right

roof side rails

5a and 5b. The roof 3 of the vehicle 2 is provided with a plurality of (five in each figure) roof reinforcements at appropriate intervals in the longitudinal direction of the vehicle. That is, a pair of front roof reinforcements 6 and 7 are arranged at the front portion of the roof 3 , and a pair of

rear roof reinforcements

8 and 9 are arranged at the rear portion of the roof 3 . A rear end roof reinforcement 10 is arranged at the rear end of the roof 3 . Here, both ends in the longitudinal direction (both ends in the vehicle width direction) of each of the roof reinforcements 6 to 10 are fixed together with the roof panel 4 to the left and right

roof side rails

5a, 5b. Each of the roof reinforcements 6 to 10 is fixed to the lower surface of the roof panel 4 at both ends in the widthwise direction (both ends in the longitudinal direction of the vehicle). For example, as shown in FIG. 6, the rear roof reinforcement 8 on the front side is formed in the shape of a groove having a substantially U-shaped cross section. 81 and 82 are formed by bending. The rear roof reinforcement 8 on the front side is fixed to the roof panel 4 at its

flange portions

81 and 82 .

Further, referring to FIGS. 1 and 2, in the front part of the roof panel 4, in a range surrounded by the left and right

roof side rails

5a, 5b and the front and rear front roof reinforcements 6, 7, a rectangular shape extending to the left and right is provided. is provided with a front opening 3a. A front sunroof portion 20 is provided in the front opening portion 3a of the roof panel 4. As shown in FIG. In the rear portion of the roof panel 4, a rectangular rear opening 3b extending in the left and right direction is provided in a range surrounded by left and right

roof side rails

5a and 5b and front and rear

rear roof reinforcements

8 and 9. As shown in FIG. The rear opening 3b of the roof panel 4 is formed to be larger than the front opening 3a, and is provided with a rear sunroof 30, which will be described later.

[Vehicle sunroof structure]
1 to 3, the vehicle sunroof structure SM comprises the rear sunroof portion 30, the left and right

roof side rails

5a and 5b, and the front rear roof reinforcement 8. As shown in FIGS. That is, the left and right

roof side rails

5a and 5b correspond to the first frame member of the present invention, and the front rear roof reinforcement 8 corresponds to the second frame member of the present invention. The rear sunroof portion 30 corresponds to the sunroof portion of the present invention, and is connected to the left and right roof side rails 5a and 5b and the front rear roof reinforcement 8 via a plurality of types of connecting members 41 to 44, which will be described later. In the vehicle sunroof structure SM configured as described above, consideration should be given to avoiding an increase in the weight of the vehicle 2 as much as possible while preventing the rear sunroof portion 30 from resonating with vibrations of the vehicle body. Therefore, in the present embodiment, the resonance of the rear sunroof portion 30 is suppressed while suppressing the increase in the weight of the vehicle 2 by means of

axial coupling members

41, 42 and

coupling members

43, 44, which will be described later. Each configuration of the vehicle sunroof structure SM will be described in detail below.

[Rear sunroof (sunroof)]
As shown in FIGS. 2 and 3, the rear sunroof portion 30 shown in FIG. 1 has a rectangular roof glass 31 elongated in the left and right direction and an opening reinforcement 33, which will be described later, fixed to a receiving portion 32 of the rear opening portion 3b. consists of Here, as shown in FIGS. 4 to 6, the receiving portion 32 of the rear opening 3b is a portion that is stepped down from the entire circumference of the inner edge of the rear opening 3b, and is formed so that the roof glass 31 can be fitted therein. It is As shown in FIG. 5, the roof glass 31 is arranged substantially flush with the roof panel 4 with its outer edge fixed to the receiving portion 32 with an adhesive 321 . A weather strip 322 is provided between the roof glass 31 and the rear opening 3b (receiving portion 32) to seal the gap.

A plate-like opening reinforcement 33 fixed to the lower surface of the receiving portion 32 of the roof panel 4 is provided on the periphery of the rear sunroof portion 30, as shown in FIGS. As shown in FIG. 3, the opening reinforcement 33 is formed by forming a right frame portion 311 and a left frame portion 312 extending in the front-rear direction and a front frame portion 313 and a rear frame portion 314 extending in the vehicle width direction into a rectangular shape. consists of A left frame portion 312 located on the left side of the rear sunroof portion 30 is fixed to the left receiving portion 32 and protrudes outward (to the left in the figure). It protrudes outward (to the right in the figure) while being fixed to the receiving portion 32 . Further, as shown in FIG. 6, the front frame portion 313 positioned at the front portion of the rear sunroof portion 30 projects outward (forward) while being fixed to the front receiving portion 32, and the rear frame portion 313 is positioned at the rear portion. The portion 314 also protrudes outward (rearward) while being fixed to the receiving portion 32 on the rear side. Thus, the rear sunroof portion 30 is provided on the roof 3 so as to be integrated with the roof panel 4 by fixing the roof glass 31 and the opening reinforcement 33 to the receiving portion 32 .

[Shaft connecting member]
The rear sunroof portion 30 shown in FIG. 3 is connected to the left and right

roof side rails

5a, 5b (first frame members) via left and right axial connecting

members

41, 42. As shown in FIG. The left and right axial connecting

members

41 and 42 are provided at positions where the center of gravity 300 of the rear sunroof portion 30 can be supported. In the present embodiment, an imaginary axis VL1 passing through the center of gravity 300 of the rear sunroof portion 30 and extending in the vehicle width direction (horizontal direction) is assumed. Left and right on-axis coupling members 41 (42) arranged on the imaginary axis VL1 are fixed across the rear sunroof portion 30 and the corresponding roof side rails 5a (5b). In this way, the center of gravity 300 of the rear sunroof portion 30 is supported by the axial connecting

members

41 and 42, and the rear sunroof portion 30 and the left and right roof side rails 5a and 5b (first frame members) are connected. can be done.

Here, the right axial coupling member 41 and the left axial coupling member 42 shown in FIG. 3 have substantially the same structure except that they are bilaterally symmetrical. The right axial coupling member 41 is fixed across the rear sunroof portion 30 and the right roof side rail 5a on the virtual axis VL1. Referring to FIGS. 3 and 4, the right axial coupling member 41 is gradually inclined downward toward the outside in the vehicle width direction (right side in the drawings), and extends from the front edge, right edge, and rear edge. A peripheral flange portion 411 that protrudes outward is formed in the portion of . 4, the left peripheral flange portion 411 of the right axial connecting member 41 is fixed to the right frame portion 311 of the opening reinforcement 33 while being superimposed thereon. Also, the left peripheral flange portion 411 is fixed to the inner panel 51 of the right roof side rail 5a while being superimposed thereon. The left axial connecting member 42 shown in FIG. 3 is also bridged between the left frame portion 312 of the rear sunroof portion 30 and the left roof side rail 5b so as to be bilaterally symmetrical with the right axial connecting member 41. (In the left shaft connecting member 42 in FIG. 3, for the sake of convenience, the reference numerals of the portions common to the right shaft connecting member 41 are omitted.).

Here, the left and right axial connecting

members

41 and 42 shown in FIG. 3 have higher rigidity than the later-described connecting

members

43 and 44 from the viewpoint of securing the attachment (supportability) of the rear sunroof portion 30 to the roof 3. is desirable. For example, as a method of increasing the rigidity of each of the on-

shaft connecting members

41 and 42, the dimension in the width direction perpendicular to the bridging direction (the front-rear direction in the figure) may be relatively increased, or a relatively high-rigidity material may be used. can be exemplified. Further, referring to FIGS. 3 and 7, for example, the right shaft coupling member 41 may be formed in a box shape projecting downward, or may be provided with a reinforcing structure such as a bead-shaped recessed portion 412. can also increase rigidity.

[Connecting member]
Further, the rear sunroof portion 30 shown in FIG. 3 is connected to the front rear roof reinforcement 8 (second frame member) via a plurality of or a single connecting member (43, 44). The connecting members (43, 44) are provided at different positions from the on-

axis connecting members

41, 42 in order to cause the rear sunroof portion 30 to swing, which will be described later. Here, when setting the arrangement locations of the connecting members, another imaginary axis line VL2 extending in the longitudinal direction (intersecting direction) passing through the center of gravity 300 of the rear sunroof portion 30 is assumed with reference to the plan view of the roof 3 shown in FIG. do. Next, the rear sunroof portion 30 is divided into a right side 301 and a left side 302 (one side and the other side) with another imaginary axis line VL2 as a boundary. At least one of the intersection point X1 between the rear sunroof portion 30 and the other imaginary axis VL2, the right side point X2 located on the right side of the intersection point X1, and the left side point X3 located on the left side of the intersection point X1. can be provided in one location. At this time, another imaginary axis line VL2 is provided so as to be orthogonal to the imaginary axis line VL1, so that the connecting members arranged with reference to the other imaginary axis line VL2 are arranged as far away from the on-

axis connecting members

41 and 42 as possible. can be kept. Therefore, in this embodiment, as shown in FIG. 3, the rear sunroof portion 30 and the front side are connected by the right front connecting member 43 arranged at the right side X2 and the left front connecting member 44 arranged at the left side X3. and the rear roof reinforcement 8 are connected.

Here, the connecting member 43 on the front right side and the connecting member 44 on the front left side shown in FIG. 3 have substantially the same structure except for the arrangement position. The connecting member 43 on the front right side is bridged and fixed between the rear sunroof portion 30 and the rear roof reinforcement 8 on the front side at the right side portion X2. 3 and 6, the connecting member 43 on the right front side is gradually inclined downward toward the front, and has left and

right flange portions

431 and 432 projecting outward at its right and left edges. is formed. The left and

right flange portions

431 and 432 on the rear side of the connecting member 43 on the front right side are overlapped on the front edge (overhanging end) of the front skeleton portion 313 of the opening reinforcement 33 and fixed. Further, the front left and

right flange portions

431 and 432 are overlapped and fixed to the lower surface of the front rear roof reinforcement 8 . Similarly to the right front connection member 43, the left front connection member 44 shown in FIG. For the left front connecting member 44 in FIG. 3, for the sake of convenience, the reference numerals for the left and right flange portions are omitted).

[Overall configuration of sunroof]
In the rear sunroof portion 30 shown in FIG. 3, the connecting

members

43 and 44 are provided only on the front portion side (one side of the vehicle sunroof structure) where the front frame portion 313 of the rear sunroof portion 30 is located, and are separated from the virtual axis VL1. I am letting For this reason, the front side of the rear sunroof portion 30 is appropriately restrained by the connecting

members

43 and 44 so as to minimize vertical vibration. The rear side (the other side of the vehicle sunroof structure) where the rear frame portion 314 of the rear sunroof portion 30 is located is the side opposite to the front portion and on which the connecting member is not provided. For this reason, the rear portion of the rear sunroof portion 30 is relatively easily swung up and down by adjusting or controlling the rigidity of each of the connecting

members

43 and 44 as will be described later. In particular, by arranging the connecting

members

43 and 44 as far away from the imaginary straight line VL1 (the axial connecting members 41 and 42) as possible, the rear side of the rear sunroof portion 30 can be more easily swung. Further, the rear portion of the rear sunroof portion 30 is integrated with the roof panel 4 as described above, and is fixed to the rear side rear roof reinforcement 9 (second frame member) located behind it. Therefore, the rear portion of the rear sunroof portion 30 can swing up and down while the roof glass 31 can be easily attached to the roof 3 .

3 and 6, the rigidity of each connecting

member

43, 44 can be controlled by adjusting the thickness dimension D (plate thickness), and can also be adjusted by changing the type of material and structure. . Therefore, in this embodiment, the rigidity of each of the connecting

members

43 and 44 is adjusted so that the vibration mode (vibration amplitude, phase, etc.) of the rear portion of the rear sunroof portion 30 can be controlled so as to suppress resonance with the vehicle body. It is set so as to cancel the vibration of the rear sunroof part 30 that produces abnormal noise. Here, an appropriate swinging aspect of the rear sunroof portion 30 (rigidity of the connecting members 43 and 44) is not uniformly determined, but is selected in consideration of the configuration of the rear sunroof portion 30 and the vehicle as a whole. Although the method of selecting the rigidity of the connecting member is not particularly limited, for example, a plurality of connecting members having different rigidity can be prepared, and the connecting member that reduces the noise generated can be selected from among them. That is, a plurality of rear sunroof portions 30 using connecting members with different rigidity are prepared, and vibration frequencies within a predetermined range are input for each rear sunroof portion 30 . Then, in the vibration frequency (Hz) range where resonance occurs in each rear sunroof portion 30, the intensity (dB) of the generated abnormal noise is measured, and from among these, those with the intensity of abnormal noise below a predetermined target value are selected. Select.

[Behavior of vehicle sunroof structure (operation of axial connecting member and connecting member)]
In the vehicle 2 shown in FIG. 1, it is desirable that the rear sunroof portion 30 is configured so as not to resonate with the vibration of the vehicle body 11 from the viewpoint of ensuring the NV performance. For this reason, in the vehicle sunroof structure SM, as shown in FIG. Axial connecting

members

41 and 42 to be connected, and connecting

members

43 and 44 to connect the rear sunroof portion 30 to the rear roof reinforcement 8 (second frame member) on the front side at positions different from the respective axial connecting members. is provided. With the above configuration, by adjusting the rigidity of each of the connecting

members

43 and 44, the rear portion of the rear sunroof portion 30 where no connecting member is provided (the other side of the vehicle sunroof structure) is connected on the left and right shafts. The

members

41 and 42 can be swung up and down using the fulcrums (see white arrows in FIG. 6).

Therefore, in the present embodiment, as described above, the swinging aspect of the rear portion of the rear sunroof portion 30 (the rigidity of the connecting members 43 and 44) is adjusted so as to suppress resonance with the vehicle body. It is set so that the shaking of the sunroof part 30 can be canceled. Therefore, when vibrations during running of the vehicle are transmitted to the rear sunroof part 30, the rear side of the rear sunroof part 30 is forcibly shaken up and down so as to suppress resonance together with the roof panel 4 behind it. By suppressing the resonance of the rear sunroof portion 30 due to the deflection of the rear portion of the rear sunroof portion 30 in this way, it is possible to avoid the generation of abnormal noise caused by the resonance as much as possible. In the vehicle sunroof structure SM, since resonance is suppressed by vibration of the rear sunroof portion 30 (rear portion), there is no need to separately set a mass damper, and an increase in the weight of the vehicle 2 can be suppressed as much as possible. Thus, the vehicle sunroof structure SM becomes an efficient body structure capable of controlling the NV performance, and contributes to weight reduction of the vehicle 2 and optimization of the body structure. Therefore, according to this embodiment, it is possible to suppress resonance of the rear sunroof portion 30 while suppressing an increase in the weight of the vehicle 2 .

Furthermore, in the vehicle sunroof structure SM, by providing a plurality of or a single connecting member (43, 44) at desired positions with reference to another imaginary axis VL2, the rear portion of the rear sunroof portion 30 can be shaken more reliably. becomes possible. In particular, connecting members (43, 44) are provided on or in the vicinity of another imaginary axis VL2 perpendicular to the imaginary axis VL1, and are spaced apart from the on-

axis connecting members

41, 42 as much as possible. becomes easier to shake. Further, the rear side of the rear sunroof portion 30 (the other side of the vehicle sunroof structure) is reinforced by being fixed to the rear side rear roof reinforcement 9 (second frame member), which contributes to ensuring the attachment to the roof 3. configuration. In the present embodiment, by making the axial connecting

members

41 and 42, which serve as fulcrums, highly rigid, the rear side of the rear sunroof portion 30 can be shaken while ensuring the attachment of the rear sunroof portion 30 more reliably. can be made easier.

[Change example]
The vehicle sunroof structure of this embodiment is not limited to the embodiment described above, and can take various other embodiments. Although the configurations of the coupling member and the on-shaft coupling member are illustrated in this embodiment, the configuration is not limited to these configurations. For example, there may be a difference in rigidity between the connecting member and the on-shaft connecting member, or there may be no difference in rigidity. In addition, the shape of the on-axis connecting member and the connecting member may be of various shapes such as a rod shape and a column shape in addition to the plate shape. In addition, the number and positions of arrangement of the connecting members are appropriately set in consideration of the strength of the connecting members, and a single or a plurality (three or more) may be arranged. Note that the plurality of connecting members (axial connecting members) may have the same or different shapes and dimensions. Further, the connecting member shown in FIG. 3 connects the rear sunroof portion and the rear side rear roof reinforcement (second frame member) to facilitate swinging of the front side of the rear sunroof portion (the other side of the vehicle sunroof structure). can also In such a case, the front side of the rear sunroof is fixed to the front rear roof reinforcement (second frame member). The other side of the vehicle sunroof structure does not necessarily have to be fixed to the first frame member or the second frame member (for example, the rear side rear roof reinforcement shown in FIG. 3 may be omitted).

In addition, the location of the axial connecting member can be set based on the virtual axis extending in the plane direction of the roof, such as the vehicle width direction and the front-rear direction. For example, referring to FIG. 3, when an imaginary axis extending in the longitudinal direction is set, the sunroof portion and the front and rear rear roof reinforcements (second frame members) can be connected by the on-axis connecting member. In this case, the connecting member can connect either the left or right roof side rail (first frame member) to the rear sunroof portion. At this time, either the right side or the left side of the sunroof portion becomes the other side of the vehicle sunroof structure and is fixed to either the left or right roof side rail (first frame member). It is also possible to envision an imaginary axis or other imaginary axis diagonally to the polygonal sunroof section. Note that the other imaginary axis can be extended in any direction that intersects the imaginary axis, and does not necessarily have to be orthogonal.

Also, the configurations of the vehicle 2, the roof 3, and the sunroof portion 30 can be changed as appropriate. For example, the sunroof portion can be provided at an appropriate position on the roof (for example, the position of the front sunroof portion or the rear end side of the roof). Also, the shape of the sunroof can be set to various polygonal shapes, circular shapes, semicircular shapes, and elliptical arc shapes in addition to rectangular shapes when viewed from above. Also, the structure and arrangement method of the roof glass and the structure and arrangement method of the opening reinforcement can be appropriately set according to the structure of the vehicle. As for the fixing method of the roof glass and the opening reinforcement, various methods such as adhesion, fastening, and welding can be adopted depending on the material. Various reinforcing structures (rigid structures) provided on the roof can be used as the first frame member and the second frame member. good.
