It is AA sectional drawing of the door striker attachment structure for vehicles of Fig.1 (a). It is a figure which expands and shows a part of vehicle door striker attachment structure of FIG.1 (b). It is a B arrow view of the door striker mounting structure for vehicles of FIG.

  A representative configuration of a vehicle door striker mounting structure according to an embodiment of the present invention is a pillar that configures a rear edge of a rear door opening on a side surface of a vehicle, and a pillar to which a striker that keeps the rear door closed is mounted. In the vehicle door striker mounting structure including the reinforcement for reinforcing the pillar, the pillar includes a first portion parallel to the vehicle side surface and a second portion extending from the rear end of the first portion to the vehicle width direction outer side and the vehicle rear side. An inner panel including: a third portion disposed on the outer side of the first portion of the inner panel in parallel with the first portion; a fourth portion on which a striker is attached extending from the rear end of the third portion toward the outer side in the vehicle width direction; The reinforcement includes a support portion that overlaps the rear side of the fourth portion of the outer panel and supports the striker together with the fourth portion, and an inner portion of the support portion in the vehicle width direction. One end extending from the end to the front of the vehicle and joined to the first part of the inner panel; the other end extending from the outer end in the vehicle width direction of the support part toward the second part of the inner panel and joined to the second part; It is characterized by having.

  According to the above configuration, the reinforcement has one end continuous to the support part supporting the striker joined to the first part of the inner panel, and the other end continuous to the support part joined to the second part of the inner panel. ing. For this reason, the reinforcement forms a closed section together with the inner panel. Therefore, the rigidity of the reinforcement including the support portion that supports the striker is improved. Further, the reinforcement support portion is overlapped with the fourth portion of the outer panel to which the striker is attached. For this reason, even if the load accompanying the vibration of the vehicle door during vehicle travel is transmitted to the fourth portion of the outer panel via the striker, the striker can be supported by the reinforcement support portion having improved rigidity. Therefore, deformation of the fourth portion of the outer panel can be suppressed.

  The other end of the reinforcement is preferably parallel to the one end. Thus, the one end part and the other end part of the reinforcement joined respectively to the 1st site | part and 2nd site | part of an inner panel are parallel. For this reason, before joining the reinforcement to the inner panel, the position of the reinforcement can be adjusted in the vehicle longitudinal direction and the vehicle vertical direction with respect to the inner panel. And it can suppress that a clearance gap generate | occur | produces between a support part and a 4th site | part by adjusting the position so that the support part of a reinforcement may contact | connect the 4th site | part of an outer panel. If the striker is attached to the fourth part and further supported by the support part in a state where a gap is generated, residual stress that causes a crack is generated in the fourth part of the outer panel. Therefore, according to the said structure, it can reduce that a crack generate | occur | produces in the 4th site | part of an outer panel in the state which attached the striker.

  One end of the reinforcement is joined to the first portion of the inner panel at two locations spaced in the vehicle vertical direction, and the other end of the reinforcement is connected to the inner panel at two locations spaced in the vehicle vertical direction. It is good to be joined to the 2nd part. If the dimensional accuracy of the inner panel is low, the first part and the second part of the inner panel may not be formed in a planar shape extending in the vehicle vertical direction. However, in the above-described configuration of the present invention, one end and the other end of the reinforcement are joined to the first part and the second part of the reinforcement, respectively, at two locations separated in the vehicle vertical direction. For this reason, even when the dimensional accuracy of the inner panel is low, the reinforcement can be joined thereto, and the position of the reinforcement can be adjusted in the vehicle longitudinal direction and the vehicle vertical direction with respect to the inner panel.

  The lower end part of said inner panel is good to be joined to the wheel house which stores the rear wheel of vehicles. As a result, the load received by the inner panel is transmitted and distributed to the wheel house via the lower end portion of the inner panel. For this reason, the rigidity of the inner panel can be increased and deformation can be suppressed.

A lower end 120 of the inner panel 118 is joined to a wheel house 122 that houses a rear wheel (not shown) of the vehicle.

  The vehicle door striker mounting structure 100 further includes a striker reinforcement (reinforce 124) shown in FIG. The reinforcement 124 is joined to the inner panel 118 of the pillar 106 and reinforces the pillar 106. In the reinforcement 124, two support holes 126a and 126b that are spaced apart in the vehicle vertical direction are formed. These support holes 126a and 126b are overlapped with the insertion holes 114a and 114b of the outer panel 104, respectively, and the tightening bolts 116 are inserted therethrough.

  In the vehicle door striker mounting structure 100, for example, a load accompanying vibration of a rear door during traveling of the vehicle is transmitted to the outer panel 104 of the pillar 106 via the striker 112. Therefore, in this embodiment, a configuration is adopted in which the deformation of the pillar 106 can be suppressed even when the pillar 106 receives a load via the striker 112 when the vehicle is traveling.

  FIG. 2 is a cross-sectional view taken along line AA of the vehicle door striker mounting structure 100 of FIG. As illustrated, the inner panel 118 of the pillar 106 includes a first portion 128 parallel to the vehicle side surface 102 and a second portion 130. The second portion 130 has a flange 134 that extends outward from the rear end 132 of the first portion 128 in the vehicle width direction and further extends rearward of the vehicle.

  The outer panel 104 of the pillar 106 includes a third portion 136 and a fourth portion 138. The third portion 136 is disposed on the vehicle exterior side of the first portion 128 of the inner panel 118 in parallel with the first portion 128. The front end 136a of the third portion 136 of the outer panel 104 is joined to the front end 128a of the first portion 128 of the inner panel 118. The fourth portion 138 is a portion to which the striker 112 is attached, and extends outward from the rear end 140 of the third portion 136 in the vehicle width direction.

  The reinforcement 124 has a support portion 142. The support portion 142 overlaps the rear side of the fourth portion 138 of the outer panel 104 and supports the striker 112 together with the fourth portion 138. A pedestal 144 and a nut 146 are provided on the rear side of the support portion 142 (see FIG. 3). The nut 146 is fixed to the base 114 so as to be screwed with the tightening bolt 116.

One end portion 148 of the reinforcement 124 extends from the inner end 152 of the support portion 142 in the vehicle width direction and is joined to the first portion 128 of the inner panel 118. The other end portion 150 of the reinforcement 124 extends from the outer end 154 in the vehicle width direction of the support portion 142 toward the second portion 130 of the inner panel 118 and is further joined to the flange 134 of the second portion 130. In this way, the reinforcement 124 forms a closed section 156 together with the inner panel 118. The one end portion 148 of the reinforcement 124 may be joined to the first portion 128 of the inner panel 118 in order to form the closed cross section 156, and does not need to extend to the front end 128a of the first portion 128 forward of the vehicle.

  Further, the first part 128 of the inner panel 118 and the flange 134 of the second part 130 both extend in the vehicle front-rear direction and are parallel to each other as shown. Further, in the reinforcement 124, one end 148 joined to the first part 128 and the other end 150 joined to the flange 134 of the second part 130 are parallel to each other. Therefore, the position of the reinforcement 124 can be adjusted in the vehicle longitudinal direction and the vehicle vertical direction with respect to the inner panel 118 in a state before being joined to the inner panel 118 (a chain line in the figure).

  Here, the case where the reinforcement 124 before joining to the inner panel 118 is moved to the vehicle front side is shown. That is, the support portion 142 of the reinforcement 124 is overlapped with the fourth portion 138 of the outer panel 104 from the rear side, and the position is adjusted so that the support portion 142 and the fourth portion 138 are in contact with each other. Thereby, it can suppress that a clearance gap produces between the support part 142 of the reinforcement 124, and the 4th site | part 138 of the outer panel 104. FIG.

  If the striker 112 is attached to the fourth portion 138 and further supported by the support portion 142 in a state where a gap is generated between the fourth portion 138 and the support portion 142, the fourth portion 138 of the outer panel 104 may cause a crack. Residual stress is generated. Therefore, by adjusting the position of the reinforcement 124 in the vehicle front-rear direction and the vehicle vertical direction with respect to the inner panel 118 to suppress the generation of a gap, the fourth portion 138 of the outer panel 104 is cracked with the striker 112 attached.
