Cover for hinge and hinge device for flip-up hood {COVER FOR HINGE AND HINGE DEVICE FOR FLIP-UP TYPE HOOD}

The present invention provides a hinge cover and a flip suitable for a hinge device of a flip-up hood that flips up the rear end portion of the hood when the vehicle collides with the obstacle, thereby absorbing the shock when the obstacle falls on the hood. A hinge device for an up-type hood.

13 illustrates a flip-up hood structure disclosed in Patent Document 1. As shown in FIG. The hood structure is interposed between the hood 110 and the corresponding portion of the vehicle body G to support the rear end of the hood 110 in a normal state so as to be openable and to operate when a collision load is input to the front end of the vehicle body. The hinge device (hood hinge 130) which presses a part of a structural member by the actuator 140 to flip up a hood rear end is used. The hinge device 130 includes a hood side link 131, a vehicle body side link 132, an intermediate link 133, a lock piece 138, and a spring 139 disposed between both links 131 and 132. .

Among them, one end of the link 131 is mounted on the bottom surface of the hood 110, and the other end thereof is rotatably connected to one end of the intermediate link 133 by the support pin 134. On the front side of the link 131, the support piece 143 which abuts with the rod 141 of the actuator 140 is mounted. The link 132 corresponds to a bracket mounted on the vehicle body G side, includes a U-shaped engaging portion 132a on the rear side, a slide hole 135 extending from the front side to the rear halfway, and a slide hole ( The holding part 135a extended in the downward direction at the rear end of the 135 is formed. The lock piece 138 is rotatably connected to the link 132 via a pin 137. The lock piece 138 has a lock protrusion 138a at its distal end, and is supported by a spring 139 disposed between the front part of the link 132 in a clockwise direction to support the engaging portion 132a. The fitted state of the pin 134 is held by the lock protrusion 138a. In this state, the hood 110 is normally opened and closed about the support pin 134. In addition, a guide pin 136 formed on the other end side of the intermediate link 133 is slidably engaged with the slide hole 135. In addition, when the front end of the vehicle body collides with an obstacle such as a pedestrian, the actuator 140 operates the sensor to detect the collision and protrude the rod 141 through the control unit in an instant.

In the hinge device 130, as shown in FIG. 13 (a), the hood 110 is pivoted upward with respect to the engaging portion 132a by lifting the front end of the hood 110. As shown in FIG. . On the other hand, when the front surface of the vehicle collides with the obstacle, as shown in FIG. 13 (b), the rod 141 of the actuator 140 protrudes and abuts against the support piece 143 to bring the link 131 upward. Pressure Then, the support point pin 134 presses in the direction which pushes the lock-doll jaw 138a, and the lock piece 138 rotates counterclockwise against the holding force of the spring 139. FIG. As a result, the support pin 134 is pulled out of the engaging portion 132a and the rear end of the hood 110 is flipped up. At this time, the guide pin 136 is moved to the rear of the vehicle body along the slide hole 135 and finally engaged with the holding portion 135a. In this flip-up state, the shock when the obstacle falls on the hood can be effectively alleviated or absorbed.

Patent Document 1: Japanese Patent Laid-Open No. 2005-225392

In the flip-up hood structure, when the hood 110 is normally switched from the closed state covering the engine room to the open state, the constituent members of the hinge device 130 are exposed as shown in FIG. Worse This is a constituent member of the hinge device 130, in particular, because the support piece 143, etc., which is pressed upward by the actuator 140 is inside the hood, it becomes a factor that is easily noticeable in the open state of the hood and worsens the appearance.

As a countermeasure, it is also conceivable to cover, for example, a member disposed inside the hood with a dedicated cover among the constituent members of the hinge device 130. Such a cover, however, becomes expensive if, for example, the rod 141 of the actuator 140 is made to withstand rigidity, and if the rod through-hole is formed, the appearance characteristics are not satisfied. In addition, the flip device for the flip-up hood as shown in the present invention, i.e., in a state in which the links, which are constituent members of the hinge device, are integrally constrained through the lever, by pressing the lever by the rod of the actuator, the flip is flipped. In the structure which can be switched to the non-constrained state at the time of up, since the rod is pressed against the lever via the cover counterpart, the operation timing becomes a factor.

Accordingly, an object of the present invention is a hinge cover and a flip provided with the same, which does not interfere with the pressing operation of the actuator even when covering the component members disposed inside the hood, among the components of the hinge device for a flip-up hood. A hinge device for an up type hood is provided.

In order to achieve the above object, the hinge cover of the present invention is constituted by an actuator interposed between the hood and the vehicle body to support the hood so as to be openable and close, and actuated when a collision load is input to the front end of the vehicle body. It is used in the hinge device which presses a part of a member and makes a hood riseable, and includes the part pressed by the said actuator among the structural members of the hinge device, and does not prevent the press operation of the actuator. The contact part is formed.

The hinge cover covers at least one of the constituent members of the flip-up hood hinge device interposed between the vehicle body and the hood, including at least a portion pressed by an actuator operating when a collision load is input to the front end of the vehicle body; It is essential to form a contact portion which does not interfere with the pressing operation of the actuator. At this time, "hood" is also called a bonnet. The "collision load" is usually detected by a sensor or the like provided at the front end of a hood that an obstacle collides with the front end of the hood, and this detection signal is sent to the control unit, which is sent to the actuator as an operation signal. In the case of the hinge device for a flip-up hood shown in the form example, "the location pressed by the actuator" corresponds to the press-up part 23a of the lever pressed by the rod of the actuator, for example, and the flip-up hood of FIG. In the case of application to a molten hinge device (hood hinge), it corresponds to the supporting piece 43 pressed by the rod of the actuator.

In addition, the present invention is more preferably embodied as follows.

(1) The said contact part is comprised in the partition easily formed through a some slit part (claim 2).

(2) The said contact part is a structure in which deformation is easily formed through the some slit part (claim 3).

(3) The said contact part is a structure in which deformation | transformation is easily formed through a corrugated pipe shape part (claim 4).

(4) The contact portion is detachably attached to the opening portion formed in the corresponding portion (claim 5).

(5) It is the hinge apparatus for flip-up hoods provided with the hinge cover in any one of Claims 1-5 (claim 6).

The hinge cover of claim 1 prevents the pressurizing operation of the actuator in a state where it is covered by at least one of the constituent members of the hinge device for the flip-up hood including a portion pressed by an actuator operating when a collision load is input to the front end of the vehicle body. The contact part which does not form is formed. For this reason, in the present invention, in the structure in which the hood is flipped up by pressing the constituent members of the hinge device with the actuator, even if the constituent members of the hinge device disposed on the inner surface of the hood are covered, the pressing operation of the actuator is formed on the cover. Since it is performed without any trouble through the contact portion, the appearance characteristics can be improved without disturbing the pressing operation of the actuator.

The hinge cover of claim 2 is a contact portion of the cover which does not interfere with the pressing operation of the actuator, and the contact portion is formed to be easily partitioned through a plurality of slits as illustrated in FIGS. 1 and 2. As an advantage, it is possible to easily satisfy the design separation load required for the contact portion by the number of the slit portions, the width dimension of the connection portion between the slit portions, and the like.

The hinge cover of claim 3 is an abutting portion of the cover which does not interfere with the pressing operation of the actuator, and is configured to be easily deformed by a plurality of slit portions as illustrated in FIG. 9. The number of parts, the dimension of the width of the slit part, and the like can easily satisfy the design deformation load required for the contact part.

The hinge cover of claim 4 is an abutting portion of the cover which does not interfere with the pressing operation of the actuator, and is configured to be easily deformed by the corrugated pipe portion as illustrated in FIG. By devising the shape of the shape part, the design deformation load required for the contact part can be easily satisfied.

The hinge cover of claim 5 is an abutting portion of the cover which does not interfere with the pressing operation of the actuator, and has a detachable cap configuration as illustrated in FIG. 11. It is possible to simply meet the design separation load required for the abutment.

The hinge device for a flip-up hood of Claim 6 is a structure which flips up a hood by pressing the structural member of a hinge apparatus by an actuator, and has a hood by the cover for hinges of any one of Claims 1-5. Even if it covers the structural member of the hinge apparatus arrange | positioned inside, pressing operation of an actuator is performed without a trouble through the contact part formed in the cover. Therefore, in the present invention, it is possible to improve the appearance characteristics inside the hood without disturbing the pressing operation of the actuator.

EMBODIMENT OF THE INVENTION Hereinafter, the example which applied this invention is demonstrated with reference to drawings. In this description, after the present invention is clarified by Figs. 1 to 8, a modification of the hinge cover shown in Figs. 9 to 11 will be described.

(The whole structure)

12 is a schematic perspective view of a vehicle to which the present invention is applied. The vehicle 1 (car) of FIG. 12 has an engine compartment between the front end portion 10 of the vehicle body, both side bodies 11, and the bottom of the front glass 12, and the engine compartment is a flip-up hood 15. Covered by). The hood 15 is operated when the rear end 15a is supported to be opened and closed by the left and right hinge devices 2 and 2 and is installed in the engine room so that a collision load is input to the front end 10 of the vehicle body. A part of the constituent members of the hinge device 2 is pressed by the actuator 6 to be flipped up with the rise of the vicinity of the rear end 15a. Of course, the hood 15 is closed, and the front end 15b is locked by the lock mechanism 16.

The hood 15 has a structure in which the outer panel 17 and the inner panel 18 are polymerized as shown in the schematic enlarged portion of FIG. 12. On the left and right sides of the rear end portion 15a, between the panels 17 and 18, each hinge device 2 is attached to a bracket 5 on which the hinge body 2 is fixed to the vehicle body side. In the state rotatably supported through the structure, the constituent members of the hinge device 2 described later are arranged, and they are covered by the cover 4 to which the present invention is applied. For this reason, the inner panel 18 is open | released 18a so that the location corresponding to the contact part 45 of the cover 4 or the cover 4 may be exposed. The inner panel 18 is omitted in FIGS. 1 and 2, 5 and 6.

On the front side of the front bumper 13 and the hood 15 attached to the lower side of the front end 10 of the vehicle body, a sensor 14 as collision detection means for detecting collision with an obstacle such as a pedestrian is provided. The sensor 14 is connected to the control unit 7 in the vehicle interior. The control unit 7 determines whether to flip up the hood 15 according to the detection information from the sensor 14, and if it is determined to flip up, outputs an operation signal to the actuator 6. The actuator 6 has a protruding rod 6a, a gas generating means 6b, and the like. The gas generating means 6b generates gas in response to an operation signal from the control unit 7, and the rod is driven by this gas pressure. It is a structure which protrudes (6a) in an instant.

(Hinge Device)

The left and right hinge devices 2 are interposed between the rear end side of the hood 15 and the vehicle body (rear end side in the engine room) to support the rear end 15a of the hood 15 so as to be openable and close, It is sufficient if the actuator 6 presses a part of the constituent members so that the rear end 15a of the hood 15 can be raised, that is, flipped up. In this example, it is embodied as shown to FIG. In addition, since the left and right hinge devices 2 and the left and right actuators 6 are structurally the same (however, in the case of the hinge device 2, the bent shape of the arm, the first link 21, etc.) is changed. ) Only one side is described and the other side is omitted.

1 to 4, the hinge device 2 has a first spring 21, a second link 22, a lever 23, and a stop spring 24 for holding the lever 23 in one direction. These are arranged between the bracket 5 fixed to the vehicle body side and the bracket 3 fixed to the outer panel 17 side of the hood 15. Therefore, the hinge device 2 is constituted as the hinge unit 20 by the first link 21, the second link 22, the lever 23, the tangent spring 24, and the bracket 3, but the bracket ( It can also be grasped as the hinge unit 20, including 5).

That is, the auxiliary link 25 and the auxiliary link 26 are pivotally connected to the bracket 5 at the other end of the auxiliary link 25 in a state in which one end thereof is swingably connected by the axis 19b. The other end of the link 26 is pivotally connected to the first link 21 by an axis 19d (see FIG. 4). These are added as needed, and are abbreviate | omitted in FIG. 5 and FIG.

At this time, the bracket 5 is substantially L-shaped in cross section, and forms the vehicle body attachment portion, the first link shaft hole, and the like. On the other hand, the bracket 3 is a structure in which the inner plate is integrally bonded to the outer plate, and the cross section forms a substantially c-shape, and is composed of the intermediate plate portion 30 and both side portions 31. The intermediate plate part 30 is provided with the support pieces 32 and 32 for levers which protruded against the front-back end part, the window part 33, etc. which let the corresponding part of the lever 23 pass. Although only one side is shown in the figure on both sides 31, a plurality (two) of rectangular engaging holes 34 for covering are respectively formed in opposing states.

One end of the second link 22 is swingably connected to one side portion 31 of the bracket 3 via the shaft 19e, and the other end is swinging through the shaft 19f to the other end of the first link 21. It is possibly connected. Moreover, the lever 23 is hold | maintained by the bracket 3 by the support piece 32 and the support piece 32 so that rotation is possible.

The lever 23 protrudes from the periphery of the substantially cylindrical body and is disposed opposite to the window portion 33, and protrudes from the periphery of the main body in the other direction of the pressing portion 23a to the first link. It has the restricting part 23b which restrains 21 to the bracket 3 (the 1st link 21 does not move with respect to the bracket 3). Although the restriction | limiting part 23b of FIG. 3 was typical, in addition to this, the structure which enables the 1st link 21 and the 2nd link 22 to be restrained to the bracket 3 together may be sufficient.

3 is a coil type as shown in FIG. 3, and one end 24a is caught by the bracket 3 in the state wound by the corresponding part of the lever main body, and the other end 24b is caught by the back side of the press part 23a. have. In the state of the same figure, the lever 23 presses and restrains the 1st link 21 to the bracket 3 side via the restricting part 23b by the holding force of the finger spring 24. As shown in FIG. And the lever 23 is rotated to the window part 33 side by the press part 23a resisting the holding force of the finger spring 24 by the actuator 6, and the restricting part 23b will also be connected with the 1st link 21. They are rotated together in the same direction and away from the bracket 3. As a result, the bracket 3 and the hood 15 are flipped up using the pivot 19e of the second link 22 as a supporting point. 3 and 4, reference numeral 29 denotes an attachment member such as a bolt-nut for attaching the bracket 3 to the hood 15 side.

(cover)

The cover 4 is used for the hinge device 2, covers a portion pressed by the actuator 6 among the constituent members of the hinge device 2, and hinders the pressing operation of the actuator 6. The contact part 45 which does not have is formed. In this example, it is embodied as shown to FIG. 1, FIG. 7, and FIG. In addition, although the position of the link insertion part etc. changes to right or left depending on whether the hinge device 2 of the left side or the hinge device 2 of the right side changes, the cover 4 is functionally the same, and only one side is demonstrated and the other side is abbreviate | omitted. do.

1, 7 and 8, the cover 4 is made of a resin injection molded body, the hinge device 2 in a state in which the hinge device 2 is attached to the hood 15 through the bracket 3; ) Is formed in a container shape covering most of the first link 21 except for the base end side. Specifically, it is a circumferential wall standing up in the container bottom wall 4a, and has a slightly lower front wall 40 disposed on the front side of the vehicle body, a rear wall 41 disposed on the front glass side, and both side walls 42, 43. have. In addition, an opening is formed between the rear wall 41 and the side wall 43 so that the link insertion portion 44 into which the first link 21 can be inserted in the cover with a margin.

The contact part 45 is formed in the container bottom wall 4a in the state partitioned by the some slit part 46. As shown in FIG. This contact part 45 is set in the position corresponding to the rod 6a of the actuator 6, or the position corresponding to the pressing part 23a of the lever 23 which comprises the hinge apparatus 2, and a link It is formed at the position displaced from the front of the insertion part 44 to the side wall 42 side. In this example, a plurality of slit portions 46 are formed at equal intervals on the line of the circle, and the slit portions 46 are connected to the bottom wall 4a by the break connection portions 45a. In shape, the contact part 45 may form the some slit part 46 and the connection part 45a on an ellipse or a square line. In addition, when the rod 6a contacts the contact part 45 as shown in FIG. 2 (b), the slit part 46 and the connection part 45a operate normally for the actuator 6 to operate. It sets to the number or length (slit part), width (connection part), etc. which are easily isolate | separated from the container bottom wall 4a, without disturbing.

Moreover, the some engagement part 47 is formed in the inner surface of both side walls 42 and 43 opposingly. Each engaging portion 47 forms a hollow protrusion on the inner surface of the side wall as inferred in FIGS. 8 (b) and 8 (d), and two protrusions 48 are formed on the protrusion. Configuration. Each protrusion 48 is partitioned by a c-shaped slit 47a. In Fig. 7, reference numeral 49a denotes an auxiliary attachment hole for fixing the cover 4 to the bracket 3 as required by bolts or the like, and reference numeral 49b passes through a member for attaching the bracket 3 to the hood. The through hole to be made, reference numeral 49c, is a cover positioning part, and reference numeral 49d is a temporary fixing part. These are suitably employ | adopted according to the structure, shape, etc. of a specific cover.

(work)

The attachment method and operation characteristics of the cover 4 will be described.

(A) The cover 4 is simply attached to the bracket 3 of the hinge device by the following operation. That is, the cover 4 is, for example, as shown by the phantom line of FIG. 1, the engaging portion 47 of the cover corresponding to the engaging hole 34 of both sides 31 of the bracket described above with respect to the bracket 3. Is pressed against the bracket side, the protrusions 48 of the respective engagement portions 47 are pressed against the corresponding one-piece portions 31 and displaced so as to reduce the amount of protrusion once, and then the corresponding one-piece portions 31 are caught. When it is opposed to the hole 34, it is elastically restored and it engages with the locking hole 34, and it attaches by four engaging forces by this. In addition, when reinforcing the installation strength, for example, the screw is fastened to the corresponding portion of the bracket 3 at the attachment hole 49a. Thus, in this structure, since it is covered invisibly by the cover 4 except for the base end side of the arm (1st link 21), the external appearance characteristic can be improved in the structural member of the hinge apparatus 2. As shown in FIG.

(B) In addition, even when the hinge device 2 is normally used (when a collision load is not input to the front end portion 10 of the vehicle body), as shown schematically in FIG. When raised, the hood 15 is rotated to the upper side centering on the axis 19a, that is, the open state of the solid line, in the closed state of the virtual line. At this time, since the first link 21 is constrained to the bracket 3 by the restricting portion 23b of the lever 23 as shown in FIG. 3, the second link 22, the bracket 3, and the hood 15 are provided. ) Is integrally moved in the opening direction in conjunction with the rotation of the first link 21.

(C) On the other hand, when the vehicle 1 is traveling, the sensor 14 detects that an obstacle (pedestrian or the like) has collided with the front end of the vehicle body 10, and the detection signal is transmitted to the control unit 7. When the operation signal is sent from the control unit 7 to the gas generating means 6b of the actuator 6, the gas generating means 6b is driven so that the rod 6a of the actuator 6 protrudes in an instant. . In this structure, when the rod 6a abuts against the abutting portion 45 of the cover, the abutting portion 45 is divided into a plurality of slit portions 46, so that the connecting portion is formed by the pressing force of the rod 6a. 45a is broken and is easily separated from the container bottom wall 4a. Then, as shown in FIG. 2 (b), the pressure of the lever 23 is pushed through the contact portion 45 from which the rod 6a is separated (or the rod 6a alone when the separated contact portion 45 falls). The pressure portion 23a is rotated toward the window portion 33 to resist the holding force of the tangent spring 24, whereby the rear end of the hood 15 is raised in the direction of the arrow in the figure, as shown in FIG. Is flipped up. In this flip-up state, the impact when the obstacle falls on the hood can be effectively alleviated or absorbed at the rear end of the hood.

In addition, in the process of switching to the hood flip-up state of FIG. 6, when the lever 23 is pushed upward through the rod 6a in the state of FIG. 3, the hinge device 2 rotates. ) Is rotated in the opposite direction to the pressing section 23a together with the lever-side restricting section 23b, and as a result, the direction away from the bracket 3 with the pivot 19e of the second link 22 as a supporting point. Is moved to.

Only the changes will be described in detail. That is, the abutment part 50 sets the corresponding part of the container bottom wall 4a to the thin circular part, and the several elastic piece part 51 which is easy to deform | transform the thin circular part by making the base end the support point. ) In other words, each elastic piece portion 51 is formed by a plurality of slit portions 52 extending radially toward the line of the circle at the center of the thin circular portion. When each elastic piece portion 51 is pressed by the rod 6a as shown in Fig. 9 (b), the elastic piece 51 is deformed to face upward with the supporting end of the circle as a supporting point to allow passage of the rod 6a. do. In other words, in this structure, when the rod 6a of the actuator 6 contacts each elastic piece part 51 which comprises the contact part 50, each elastic piece part 51 of the actuator 6 The number of elastic piece portions 51 or the slit portion 52 is set so as to be easily deformed without disturbing normal operation.

(Second modification)

It abbreviate | omits and only a change point is demonstrated in detail. That is, the abutment portion 53 is formed so that the corresponding portion of the container bottom wall 4a can be easily deformed by a corrugated pipe configuration, and more specifically, a circular central portion 55 having a diameter larger than that of the rod 6a, It is comprised by the corrugated tubular part 54 formed around the center part 55. As shown in FIG. When the center portion 55 is pressed against the rod 6a as shown in FIG. 10 (b), the abutting portion 53 moves the lever-side pressing portion 23a with the extending action of the corrugated tubular portion 54. Pressure In other words, in this configuration, when the rod 6a of the actuator 6 abuts against the central portion 55 constituting the abutting portion 53, the corrugated tubular portion 54 performs normal operation of the actuator 6. The shape or the like is set so as to extend easily without disturbing.

(Third modification)

The modified example of FIG. 11 changes the structure of the contact part which the rod 6a of the actuator 6 abuts among the said cover 4, Since it is the same as the said form except the contact part, it attaches | subjects the same code | symbol and is repeated description. It abbreviate | omits and only a change point is demonstrated in detail. That is, this contact part 56 is formed by attaching or detaching the corresponding part of the container bottom wall 4a by a cap structure, and has the engaging part 57 of the shape in which the cross section formed around the contact part was concave. The engaging portion 57 is detachably fitted to the engaging portion 4b having a convex shape in cross section formed in the inner circumference of the opening formed in the container bottom wall 4a corresponding to the engaging portion 56. The contact portion 56 is formed in a circular shape, but may be formed in an ellipse or a square. In this structure, the engagement part 57 and the to-be-engaged part 4b are engaged, and the rod 6a of the actuator 6 contacted the contact part 56, as shown to FIG. 11 (b).
