Description

  The present invention relates to a drain channel structure in a sunroof device for a vehicle.

  In the so-called inner slide type sunroof device, in which the roof panel is tilted down and slid rearward, if raindrops or the like adhere to the surface of the roof panel, water drops from the rear edge of the roof panel to the indoor side when tilted down. Therefore, a drain channel that is always located below the rear edge of the roof panel in conjunction with the roof panel is provided as a member that receives this (see, for example, Patent Document 1).

  5A is an external perspective view of a conventional drain channel, and FIG. 5B is a side view showing a positional relationship with a roof panel and an interior plate when the drain channel is taken along the line AA. The drain channel 31 is a long integrally formed member extending in the vehicle width direction, and is made of a pressed product of a steel plate. The cross-sectional shape is concave so as to receive water from the roof panel 32. The central portion 31a formed along the rear edge of the roof panel 32 has a constant concave cross-section, whereas the periphery of the end portion 31b is Due to the two points of fitting to the R-shaped corner portion of the roof panel 32 and attaching to the drain slider (not shown) for sliding the guide rail, the shape is a shape with a large number of bent portions.

When the roof panel 32 is closed or tilted up as shown in FIG. 5B for the purpose of ventilation or the like, the front edge of the central portion 31a of the drain channel 31 is the opening of the interior plate 33. It is in a position to face. Since a situation where a hand is put on the front edge portion of the central portion 31a is assumed depending on a person, a guard member 34 made of a rubber material or the like is attached to the front edge portion to protect the hand.
Utility Model Registration No. 2597086

  As described above, the periphery of the end portion 31b has an indefinite cross section conforming to the corner portion of the roof panel 32 and the drain slider, and has a shape with a large number of bending portions. Therefore, bending work is difficult as compared with the central portion 31a. Sag at the time of unplugging is likely to occur once. Since the conventional drain channel 31 is a member in which the central portion 31a and the pair of end portions 31b are integrally formed, for example, even when the above-described bending failure or the like occurs only in one end portion 31b, the drain channel 31. The overall yield will be reduced.

  In addition, when there are a plurality of specifications in which the width dimension (dimension in the vehicle width direction) of the roof panel 32 varies depending on the type of the vehicle, the drain channel 31 has a plurality of lengths corresponding to the width dimension of each roof panel 32. Since it is necessary to arrange them, the manufacturing cost is increased and the labor of parts management is also increased.

  The point where the guard member 34 is provided also increases the number of parts and the number of assembling steps, which increases the manufacturing cost.

  The present invention has been created to solve the above-described problems, and an object of the present invention is to provide a drain channel structure of a sunroof device that can reduce the manufacturing cost of the drain channel.

  In order to solve the above-mentioned problems, the present invention is located under the rear edge of the roof panel so as to receive water dripping from the roof panel in a vehicle sunroof device, and is attached to a drain slider interlocking with the roof panel to A drain channel structure that moves in a direction, the drain channel being positioned below a center portion of a constant cross section that extends in the vehicle width direction along the rear edge of the roof panel and below a corner portion of the roof panel. A pair of end portions of an indefinite cross section attached to the drain slider are separately formed and formed separately.

  According to this drain channel structure, since the central portion and the pair of end portions are molded separately, the yield of only the end portions where troubles are likely to occur can be reduced, and a constant cross-sectional shape that hardly causes any troubles in molding occurs. It can be used effectively without wasting the central part. Also, if there are multiple specifications with different roof panel widths due to differences in the vehicle model, etc., the drain channel can be manufactured by sharing and using multiple end panels with different lengths only at the center. Cost can be reduced.

  Further, the present invention is characterized in that a central portion of the drain channel is a resin member, and the pair of end portions is a metal plate member.

  According to this drain channel structure, it is possible to reduce the weight of the drain channel by using the central portion having a large proportion of weight as the resin member. Since it is a resin member, there is no need to separately provide a guard member such as a rubber material for protecting the hand. Since the end portion is a member having a complicated shape with an indefinite cross section and a large number of bent portions, the mold tends to be complicated if a resin member is used. Therefore, the manufacturing cost of the drain channel can be suppressed by using a metal plate member that can be pressed with a simple die.

  Further, the present invention is characterized in that at the center of the drain channel, at least a front wall portion in the vehicle front-rear direction is formed into a hollow closed cross-sectional shape.

  According to this drain channel structure, a hollow closed cross-sectional shape is provided at least in the front and rear direction of the vehicle, thereby solving the problem of torsional rigidity that occurs when a person puts his / her hand on his / her body weight. .

  Further, the present invention is characterized in that a central portion of the drain channel is a metal plate member, and the pair of end portions is a resin member.

  According to this drain channel structure, further strength can be secured in the central portion, and the manufacturing yield of the end portion can be improved.

  According to the present invention, it is only necessary to reduce the yield only at the end portion where defects are likely to occur, the center portion having a constant cross-sectional shape that hardly causes defects in molding can be used effectively without wasting, and the width of the roof panel When there are a plurality of specifications having different dimensions, only the central portion may be replaced with one having a different length, so that the structure is excellent in versatility to other models.

  FIG. 1 is an explanatory plan view of the sunroof device. The sunroof device 1 is a so-called inner slide type, which closes a rectangular opening formed in the fixed roof 2 when closed, tilts up the rear edge side when tilting up, opens the rear of the opening, and opens rear when the slide is open. A roof panel 3 (shown by imaginary lines in FIG. 1) is provided that moves to the rear with the edge side tilted down. The roof panel 3 is, for example, a glass panel.

  A pair of guide rails 4 extending in the vehicle front-rear direction are located below both side edges of the roof panel 3, and the front ends and rear end portions thereof are connected by the front frame 5 and the rear frame 6. ing. A drain channel 7 according to the present invention is located below the rear edge of the roof panel 3.

  FIG. 2 is a side view showing an example of a tilt slide mechanism. A panel support bracket 11 is fixed to the lower surface of the side edge portion of the roof panel 3 with an adhesive or the like, and a panel support stay 12 is fixed to the panel support bracket 11 with bolts or the like. The panel support stay 12 is connected to a front slider 13 and a rear slider 14 that are guided by the guide rail 4 and slide in the vehicle longitudinal direction. The front end of the panel support stay 12 is rotatably supported by the front slider 13, and the engagement pin 14 a of the rear slider 14 is engaged with a tilt-up and tilt-down cam groove 12 a formed near the rear of the panel support stay 12. ing. A push-pull cable (not shown) is connected to the rear slider 14, and the rear slider 14 and the front slider 13 are slid by driving the push-pull cable, and the roof panel 3 is tilted by the cam action of the cam groove 12a and the engaging pin 14a. Up or tilt down.

  On the guide rail 4, a drain slider 16 connected to the panel support stay 12 via the rod 15 is located behind the rear slider 14. As can be seen from FIG. 2, the drain slider 16 is positioned below the rear edge of the roof panel 3 in a side view, and moves in the vehicle front-rear direction in conjunction with the roof panel 3. A concave support portion 16a for mounting the drain channel 7 is formed on the drain slider 16, and the drain channel 7 is fixed by engaging with an engagement hole 74 (FIG. 3) of the drain channel 7. An engaging hook 16b is provided.

  FIG. 3 is an external perspective view of the drain channel 7. A drain channel 7 that is positioned below the rear edge of the roof panel 3 and receives water dripping from the rear edge is spanned between the left and right drain sliders 16, and is fixed to the drain slider 16 by the engagement hook 16 b described above. . According to the present invention, the drain channel 7 is positioned on the drain slider 16 positioned below the corner 71 of the roof panel 3 and the central portion 71 having a constant cross section extending in the vehicle width direction along the rear edge of the roof panel 3. A main feature is that the pair of end portions 72 and 73 having an indefinite cross section with respect to the vehicle width direction to be attached are separately formed and divided.

  FIG. 3 shows an example in which the central portion 71 is a resin member and the pair of end portions 72 and 73 are metal plate members such as steel plates. The end portions 72 and 73 are symmetrical. The central portion 71 is formed in a concave section so as to receive water, and a front wall portion 71a and a rear wall portion 71b are formed on the front and rear sides in the vehicle front-rear direction. Since it is assumed that a person puts a hand on the front edge of the central portion 71 and puts weight on that occasion, at least the front wall portion 71a is formed into a shape having a hollow closed cross-sectional portion 71c, and the torsional rigidity of the central portion 71 Is preferably increased. In FIG. 3, the rear wall 71 b is also provided with a hollow closed cross-section 71 d to further increase the torsional rigidity of the central portion 71.

  FIG. 4 is a side sectional view showing an example of a connecting portion between the central portion 71 and the end portions 72 and 73. In this example, the watertight seal material 17 is interposed in the concave portion of the end portion 72 or the end portion 73 and the left and right ends of the central portion 71 are placed. As the sealing material 17, a material that functions as an adhesive is preferable, and a butyl rubber type or silicon rubber type is suitable. In addition to this, for example, a mode in which the end portions 72 and 73 are placed on the left and right ends of the central portion 71, and a groove for inserting the edges of the end portions 72 and 73 on the left and right end surfaces of the central portion 71 are formed. There is a mode in which the edges of the end portions 72 and 73 are press-fitted into the groove.

  Since the end portions 72 and 73 have an indefinite cross section conforming to the corner portion of the roof panel 3 (FIG. 1) and a large number of bending portions, forming processing such as bending processing is difficult, and compared with the central portion 71. The end portions 72 and 73 are likely to have a single molding defect. On the other hand, in the present invention, since the central portion 71 and the end portions 72 and 73 are molded separately, it is only necessary to reduce the yield of the end portion 72 or the end portion 73 in which a defect has occurred. The central portion 71 having a constant cross-sectional shape that hardly occurs can be effectively used without being wasted.

  Further, when there are a plurality of specifications having different width dimensions (dimensions in the vehicle width direction) of the roof panel 3 (FIG. 1) due to differences in vehicle types, the R shape of the corner portion of the roof panel 3 does not change so much. By using the end portions 72 and 73 in common and preparing and using a plurality of the central portions 71 having different lengths, the manufacturing cost of the drain channel 7 can be suppressed.

  Furthermore, weight reduction of the drain channel 7 can be aimed at by using the center part 71 with a large ratio of weight as the resin member. Moreover, since it is a resin member, it is not necessary to separately provide a guard member such as a rubber material for protecting the hand. As described above, the end portions 72 and 73 are members having an indefinite cross section, a large number of bent portions, and complicated shapes having the engagement holes 74 and the like. Therefore, although there is a problem of manufacturing yield, the manufacturing cost of the drain channel 7 can be suppressed by using a metal plate member that can be pressed by a simple die.

  Further, by forming at least the front wall portion (front wall portion 71a) in the front-rear direction of the vehicle into a hollow closed cross-sectional shape, twisting of the central portion 71 that occurs when a person puts his / her hand on the body weight is suppressed. The

  The best embodiment of the present invention has been described above. If the central portion 71 needs a further strength and the end portions 72 and 73 can be manufactured at low cost by resin molding, the central portion 71 can be a metal plate member and the end portions 72 and 73 can be resin members. Good. In addition, the present invention is not limited to those described in the drawings, and various design changes can be made without departing from the spirit of the present invention.
