Abstract
Description
[Technical field]
[0001] The present invention relates to a mounting structure for a door striker of a vehicle. [Background technology]
[0002] In general, the body of an automobile vehicle has a pillar portion extending in the vertical direction, and the pillar portion forms a part of the door opening. A door striker that engages with a latch of the vehicle door is provided on the pillar portion of the door opening. The striker is disposed so as to protrude from an outer panel of the pillar portion, and engages with the latch of the vehicle door in a closed state. The outer panel of the pillar portion is formed of an exterior panel member that is integrated with a quarter panel that forms a fender portion or the like of the vehicle. Therefore, if a striker is attached to the outer panel of the pillar portion, when the vehicle door is closed, an input from the vehicle door is transmitted from the outer panel of the pillar portion to the quarter panel. As a result, there is a problem that the quarter panel vibrates and makes noise when the vehicle door is closed.
[0003] As a structure in which the striker is not directly attached to the outer panel, a pillar reinforcement is provided between the outer panel and the inner panel of the pillar section, and a nut that screws onto the tightening bolt of the striker is provided on the pillar reinforcement (see, for example, Patent Document 1). In Patent Document 1, the support part where the nut is provided in the pillar reinforcement overlaps with the outer panel, and one end and the other end continuing from the support part are each joined to the inner panel. With this striker attachment structure, the transmission of input from the vehicle door to the quarter panel is suppressed. In Patent Document 1, one end and the other end of the pillar reinforcement are parallel to each other, so that the position of the pillar reinforcement can be adjusted in the vehicle front-rear direction and the vehicle up-down direction relative to the inner panel before being joined to the inner panel. [Prior art documents] [Patent documents]
[0004] [Patent Document 1] JP 2018-203079 A Summary of the Invention [Problem to be solved by the invention]
[0005] However, in the mounting structure described in Patent Document 1, the joints between one end and the other end of the pillar reinforcement in the inner panel of the pillar part must be formed parallel to each other, which imposes significant restrictions on the shape of the inner panel. Also, the position of the pillar reinforcement relative to the inner panel must be adjusted during vehicle body assembly, which complicates the vehicle body assembly process.
[0006] The present invention has been made in consideration of the above-mentioned circumstances, and an object of the present invention is to provide a mounting structure for a vehicle door striker that suppresses noise made by the quarter panel when the door is closed and enables the position of the pillar portion of the reinforcing panel member relative to the outer panel to be accurately determined without the need for troublesome adjustment work during assembly of the vehicle body. [Means for solving the problem]
[0007] According to the present invention, there is provided a mounting structure for a door striker for a vehicle comprising: an exterior panel member forming an outer panel of a quarter panel and a pillar portion; a reinforcing panel member arranged inside the exterior panel member in the vehicle width direction for reinforcing the pillar portion, the pillar portion forming part of a door opening; and a striker provided on the vehicle body for keeping the door closed, wherein a mounting portion for the striker is provided on the reinforcing panel member, and the exterior panel member and the reinforcing panel member each have positioning holes formed therein that overlap each other in a plan view and are used when assembling the vehicle body.
[0008] According to this vehicle door striker mounting structure, the mounting portion of the striker is provided on the reinforcing panel member, so that when the door is closed, the input from the door is transmitted mainly to the reinforcing panel member via the striker, thereby suppressing the input from the door to the outer panel member and suppressing vibration and sound of the quarter panel when the door is closed. In addition, the reinforcing panel member on which the striker attachment portion is provided can be configured not to be joined to the portion of the exterior panel member that forms the design surface of the door opening. This prevents welding marks and the like from appearing on the design surface of the door opening, and improves the marketability of the vehicle compared to a case in which a reinforcing member is joined to the exterior panel member. In addition, since the outer panel member and the reinforcing panel member are formed with positioning holes that overlap each other in a plan view, the outer panel member and the reinforcing panel member can be joined after being positioned using a jig during assembly of the vehicle body. Therefore, there is no need to adjust the position of the reinforcing panel member relative to the outer panel member. As a result, the outer panel member and the reinforcing panel member are assembled with the desired positional accuracy, and excessive residual stress is not generated in the outer panel member due to a large misalignment of the outer panel member relative to the reinforcing panel member.
[0009] In the above-mentioned vehicle door striker mounting structure, the vehicle body may have an inner panel member that forms an inner panel of the pillar portion, and the reinforcing panel member may form a closed cross section together with the inner panel member.
[0010] In addition, in the mounting structure for the door striker of the above-mentioned vehicle, the inner panel member may have positioning holes that overlap with the positioning holes of the outer panel member and the reinforcing panel member in a planar view and are used when assembling the vehicle body.
[0011] In the above-mentioned vehicle door striker mounting structure, the reinforcing panel member may extend in the vertical direction, and the positioning hole of the reinforcing panel member may be provided on a lower end side of the reinforcing panel member.
[0012] Moreover, in the above-mentioned mounting structure for the vehicle door striker, the mounting portion of the striker may be a nut provided on the reinforcing panel member, and the striker may be mounted to the vehicle body by a bolt that passes through the outer panel member and the reinforcing panel member and screws into the nut. Effect of the Invention
[0013] According to the present invention, it is possible to suppress noise from the quarter panel when the door is closed, and to accurately determine the position of the pillar portion of the reinforcing panel member relative to the outer panel without performing troublesome adjustment work during assembly of the vehicle body.

[0018] As shown in Fig. 2, the striker 60 is attached to the C-pillar portion 40 of the rear door opening 12. Note that the striker 60 is indicated by a dashed line in Fig. 2. In this embodiment, the striker 60 is attached to the C-pillar portion 40 by a bolt 61 and a nut 62, as shown in Fig. 3.
[0019] As shown in Fig. 2, the vehicle body 10 has an exterior panel member 13 which forms an outer panel of the C-pillar portion 40 and also forms a quarter panel 70 behind the C-pillar portion 40. As shown in Fig. 3, the exterior panel member 13 has a vehicle width extension portion 131 extending in the vehicle width direction, a forward extension portion 132 extending forward from an inner end of the vehicle width extension portion 131, and a flange portion 133 formed at a front end of the forward extension portion 132 and offset inward in the vehicle width direction from the forward extension portion 132. The exterior panel member 13 also has a rearward extension portion 134 which connects the outer end of the vehicle width extension portion 131 and a front end of the quarter panel 70 and extends obliquely rearward toward the outside in the vehicle width direction.
[0020] The vehicle body 10 also has an inner panel member 14 which forms an inner panel of the C-pillar portion 40 and also forms a wheel house panel (not shown) behind the C-pillar portion 40. The inner panel member 14 has a vehicle width extension portion 141 extending in the vehicle width direction, a forward extension portion 142 extending forward from an inner end of the vehicle width extension portion 141, and a flange portion 143 formed at the front end of the forward extension portion 142 offset outward in the vehicle width direction from the forward extension portion 142. The inner panel member 14 also has a rearward extension portion 144 which extends obliquely rearward from the outer end of the vehicle width extension portion 141 toward the outside in the vehicle width direction. The outer panel member 13 and the inner panel member 14 are joined at the flange portions 133, 143. In this embodiment, the outer panel member 13 and the inner panel member 14 are also joined at predetermined locations between the quarter panel 70 and the wheel house panel.
[0021] The vehicle body 10 also has a reinforcing panel member 15 for reinforcing the C-pillar portion 40. The reinforcing panel member 15 has a front vehicle width extension portion 151 extending in the vehicle width direction, and a front extension portion 152 extending forward from the inner end of the front vehicle width extension portion 151. As shown in FIG. 4, the reinforcing panel member 15 has a front flange portion 153 formed at the front end of the front extension portion 152 by being offset outward in the vehicle width direction from the front extension portion 152. As shown in FIG. 3, the reinforcing panel member 15 has a rear extension portion 154 extending rearward from the outer end of the front vehicle width extension portion 151, a rear vehicle width extension portion 155 extending inward in the vehicle width direction from the rear end of the rear extension portion 154, and a rear flange portion 156 extending rearward along the inner panel member 14 from the inner end of the rear vehicle width extension portion 155.
[0022] In this embodiment, the outer panel member 13 and the reinforcing panel member 15 are not joined at the vehicle width extension portion 131 and the front vehicle width extension portion 151. The front vehicle width extension portion 151 forms the design surface of the door opening 12, and no welding marks or the like are visible on the design surface. The inner panel member 14 and the reinforcing panel member 15 are joined at the flange portion 143 and the front flange portion 153, and are also joined at the rear extension portion 144 and the rear flange portion 156. In this embodiment, the inner panel member 14 and the reinforcing panel member 15 form a closed cross section, and it can be said that the inner panel member 14 and the reinforcing panel member 15 form the framework of the vehicle body 10.
[0023] 3, a nut 62 serving as an attachment portion of the striker 60 is provided on the rear surface of the front vehicle width extending portion 151 of the reinforcing panel member 15. The location of the front vehicle width extending portion 151 where the nut 62 is provided overlaps with the vehicle width extending portion 131 of the exterior plate panel member 13. The vehicle width extending portion 131 of the exterior plate panel member 13 and the front vehicle width extending portion 151 of the reinforcing panel member 15 have insertion holes 135, 157 for the bolt 61, respectively. The striker 60 disposed in front of the vehicle width extending portion 131 of the exterior plate panel member 13 is attached to the vehicle body 10 by the bolt 61 which screws into the nut 62 provided on the front vehicle width extending portion 151 of the reinforcing panel member 15.
[0024] 2, positioning holes 136, 145 for positioning the outer panel member 13 and the inner panel member 14 are disposed in the forward extending portion 132 of the outer panel member 13 and the forward extending portion 142 of the inner panel member 14, respectively. The positioning holes 136, 145 are formed to overlap in a plan view. The outer panel member 13 and the inner panel member 14 are positioned relative to each other by pins serving as jigs that are inserted through the positioning holes 136, 145 during vehicle body assembly.
[0025] 2, a positioning hole 158 is formed in the forward extending portion 152 of the reinforcing panel member 15 for positioning the reinforcing panel member 15 with respect to the exterior panel member 13. In this embodiment, the positioning hole of the reinforcing panel member 15 is formed to overlap with the positioning holes 136 of the exterior panel member 13 and the inner panel member 14 in a plan view. As a result, the reinforcing panel member 15 is positioned with respect to the exterior panel member 13 when the vehicle body is assembled.
[0026] 4, in this embodiment, the reinforcing panel member 15 extends in the vertical direction, and is provided with positioning holes 158, 159 at the lower and upper ends, respectively, which are used for positioning with other panel members during assembly of the vehicle body. The positioning hole 159 at the upper end is formed at the upper end side of the rear extension portion 154.
[0027] According to the mounting structure for a vehicle door striker configured as described above, the nut 62 serving as the mounting portion of the striker 60 is provided on the reinforcing panel member 15, so that when the rear door is closed, the input from the rear door is transmitted mainly to the reinforcing panel member 15 via the striker 60. This suppresses the input from the rear door to the exterior panel member 13, making it possible to suppress vibration and sound of the quarter panel 70 when the rear door is closed.
[0028] In addition, the reinforcing panel member 15, on which the attachment portion of the striker 60 is provided, is not joined to the vehicle width extension portion 131 of the exterior panel member 13 that forms the design surface of the rear door opening 12, so no welding marks or the like appear on the design surface of the door opening 12. Therefore, compared to a vehicle in which a reinforcing member provided in accordance with the striker 60 is joined to the exterior panel member 13, the marketability of the vehicle can be improved.
[0029] In addition, since the positioning holes 136, 158 that overlap each other in a plan view are formed in the exterior panel member 13 and the reinforcing panel member 15, respectively, the exterior panel member 13 and the reinforcing panel member 15 can be positioned using a pin during assembly of the vehicle body before joining the panel members 13, 14, 15. This eliminates the need to adjust the position of the reinforcing panel member 15 relative to the panel members 13, 14. As a result, the exterior panel member 15 and the reinforcing panel member 13 are assembled with the desired positional accuracy, and excessive residual stress is not generated in the exterior panel member 15 due to a large misalignment of the position of the exterior panel member 15 relative to the reinforcing panel member 13.
[0030] In this embodiment, the positioning of the outer panel member 13 and the reinforcing panel member 15 is performed by utilizing the positioning holes 136, 145 and pins used for positioning the outer panel member 13 and the inner panel member 14. Therefore, there is no need to form additional positioning holes in the outer panel member 13 or to prepare additional positioning pins for use in assembling the vehicle body.
[0031] In the above embodiment, the positioning of the outer panel member 13 and the reinforcing panel member 15 is performed using the positioning holes 136, 145 and pins used to position the outer panel member 13 and the inner panel member 14, but the positioning of the outer panel member 13 and the reinforcing panel member 15 may also be performed independently of the inner panel member 14.
[0032] In addition, in the above embodiment, the reinforcing panel member 15 extends in the vertical direction, but the reinforcing panel member 15 may be provided partially in the C-pillar portion 40 in the vertical direction. In addition, the reinforcing panel member 15 does not necessarily have to form a closed cross section together with other panel members.
[0033] In addition, in the above embodiment, the striker 60 is attached to the reinforcing panel member 15 by the bolt 61 and the nut 62, but the means for attaching the striker 60 to the reinforcing panel member 15 is not limited to the bolt 61 and the nut 62.
[0034] Although the embodiments of the present invention have been described above, the invention according to the claims is not limited to the above-described embodiments. It should be noted that not all of the combinations of features described in the embodiments are essential to the means for solving the problems of the invention. [Explanation of symbols]
