Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a reinforcement structure for a strike retainer and a check link brace attached to a center pillar of an automobile.

[0002]

[Prior Art]

 A strike pillar retainer 2 and a check link brace 3 are attached to the center pillar 1 of the automobile shown in FIG. 11 as shown in FIGS.

The strike retainer 2 supports a striker 4 that engages with a latch of a front side door (not shown), while a check link brace 3 supports a check link that is inserted into a rear side door (not shown). 6, which is attached to the back surface of the pillar outer panel 5.

Specifically, the strike retainer 2 has an extending portion 21 extending forward (FR) at the inner edge of the mounting portion 20 of the striker 4, and a flange portion extending rearward at the outer edge of the mounting portion 20. 22. The extension 21 is spotted on the outer wall 5a of the front edge of the pillar outer panel 5, the mounting portion 20 is spotted on the front side wall 5b of the pillar outer panel 5, and the flange 22 is spotted on the outer wall 5c of the pillar outer panel 5. It is joined by welding.

On the other hand, the check link brace 3 has a rearwardly extending flange 31 at the inner edge of the check link support wall 30 and a forwardly extending mounting wall 32 at the outer edge of the support wall 30. The portion 31 is spot-welded to the rear flange portion 5e of the pillar outer panel 5, the support wall 30 is joined to the rear side wall 5d of the pillar outer panel 5, and the mounting wall 32 is joined to the outer wall 5c of the pillar outer panel 5 by spot welding. A similar structure is shown in, for example, Japanese Utility Model Laid-Open No. 62-94266).

[0006]

However, in the above-described conventional technique, the front side door receives an external force to the inside of the vehicle compartment at the time of a side collision of the vehicle, the striker 4 is pulled by the force L indicated by the arrow, and the result is obtained. As a result, the flange portion 22 of the strike retainer 2 receives the force M in the peeling direction indicated by the arrow.

Therefore, in order to counter the force M in the peeling direction, it is necessary to increase the plate thickness of the striking retainer 2 or to provide a separate reinforcing material, which causes an increase in weight and an increase in cost. ..

On the other hand, it is conceivable that the striking retainer 2 and the check link brace 3 are integrated with each other, but in this case, when the check link support 6 is assembled in the pillar outer panel 5, the support portion 6 of the check link is formed into the pillar outer panel. 5 interferes with the rear side flange portion 5e, and there is a problem that it cannot be inserted.

Therefore, the present invention provides a reinforcing structure of a strike retainer and a check link brace that can increase the mounting strength and the assembling workability without increasing the weight and the cost.

[0010]

[Means for Solving the Problems]

 Install the striking retainer on the back of the pillar outer panel of the center pillar from the front side wall to the outer wall, while attaching the check link brace on the back of the pillar outer panel from the rear side wall to the outer wall. Checklink the mounting wall of the striker retainer on the back side of the outer wall of the switch panel by sandwiching it between the mounting wall of the brace and the pillar outer panel, and joining the mounting wall of the striker retainer and the mounting wall of the checklink brace to the pillar outer panel I am doing it.

[0011]

[Action]

 When an external force in the diagonally forward direction is applied to the striker during a side collision of the vehicle, this external force is sandwiched between the check link brace mounting wall and the pillar outer panel outer wall, providing a strong strength to the strike retainer mounting wall. It works in the shear direction.

In addition, the mounting wall of the strike retainer and the mounting wall of the check link brace are overlapped and joined to the outer wall of the pillar outer panel, and the force applied to either the strike retainer or the check link brace is applied to the other. The center pillars will share the work and reduce the number of spot welding spots, eliminating the need for reinforcement.

[0013]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings by attaching the same reference numerals to the same portions as those of the conventional configuration.

The center pillar 1 shown in FIGS. 3 and 4 is a striker for mounting the striker 4 of the front side door shown in FIG. 2 between the upper and lower hinge mounting portions 7 of the rear side door and on the back surface of the pillar outer panel 5. The retainer 2 and the check link brace 3 having the support portion 6 shown in FIG. 2 of the check link of the rear side door are joined by spot welding.

Here, the strike retainer 2 is loosely inserted and held by the back surface of the mounting portion 20 of the striker 4 pointing forward (FR) and the claws 8 of the reinforcing flange 10 described later, as shown in detail in FIG. The striker 4 has a nut plate 9 and a flange portion 22 as a rearward mounting wall is provided on the outer edge of the mounting portion 20. The inner edge of the mounting portion 20 extends forward. An outlet 21 is provided. In addition, 10 shows the reinforcing flanges of the upper and lower edges.

On the other hand, the check link brace 3 has a supporting wall 30 which is welded to the supporting portion 11 of the check link and is directed rearward, as shown in detail in FIG. A front mounting wall 32 is provided, and a rearward flange 31 is provided on the inner edge of the support wall 30.

At the center of the mounting wall 32 of the check link brace 3, a reinforcing groove 12 is formed in the front-rear direction. In addition, 13 shows the reinforcing flanges of the upper and lower edges.

Then, as shown in FIGS. 1 to 4, the extension portion 21 and the mounting portion 20 of the strike retainer 2 are spot welded to the back surfaces of the front edge outer wall 5a and the front side wall 5b of the pillar outer panel 1, respectively. And the supporting wall 30 of the check link brace 3 are joined by spot welding to the rear side flange portion 5e of the pillar outer panel 1 and the rear surface of the rear side wall 5d, respectively, and the mounting wall 32 of the check link brace 3 is joined. A part of the lower half (shown by the shaded area in Fig. 6) is overlapped with a part of the upper half of the flange portion 22 of the striker retainer 2 (shown by the shaded area in Fig. 5), and the flange portion 22 of the strike retainer 2 is overlapped. With the mounting wall 32 of the check link brace 3 and the outer wall 5c of the pillar outer panel 1 sandwiched between the mounting wall 32 of the check link brace 3 and the stand, The flange portion 22 of the lyric retainer 2 and the outer side wall 5c of the pillar outer panel 1 are joined by spot welding. 5'denotes a pillar inner panel.

According to the reinforcing structure of the above embodiment, since the flange portion 22 of the strike retainer 2 and the mounting wall 32 of the check link brace 3 are spot welded to the pillar outer panel 5, the number of spot welding spots is increased. The load applied to either one of the striker retainer 2 and the check link brace 3 can be transmitted to the other while reducing the load, and as a result, the center pillar 1 having high strength and rigidity can be supported as a whole.

Further, when the vehicle side collision occurs, the front side door is deformed to the inside of the vehicle compartment and a diagonal forward force L acts on the striker 4 as shown in FIG. 2, but the flange portion 22 of the strike retainer 2 is a check link. Since it is sandwiched between the mounting wall 32 of the brace 3 and the outer side wall 5c of the pillar outer panel 5, the flange portion 22 of the strike retainer 2 is not caused, and the force L is sheared in the flange portion 22 in terms of strength advantageous shearing. It acts as a directional force F.

The present invention is not limited to the above-described embodiment. For example, as shown in FIG. 7, the mounting wall 32 of the check link brace 3 has a flat shape, and the striker is provided at the center of the mounting wall 32. The entire flange portion 22 of the retainer 2 may be attached.

[0022]

[Effect of the device]

 As described above, according to the present invention, when the front side door is deformed toward the inside of the vehicle in the case of a side collision of the vehicle and an oblique forward force is applied to the striker, the mounting wall of the strike retainer becomes the mounting wall of the check link brace. Since it is sandwiched between the outer wall of the pillar outer panel and the outer wall of the pillar outer panel, a shearing force, which is advantageous in terms of strength, acts on the mounting wall of the strike retainer. Therefore, the mounting strength can be increased without increasing the plate thickness or providing a reinforcing member.

Further, since the above-mentioned striking retainer and the check link brace are connected, the force applied to either one of the striking retainer and the check link brace can be distributed to the other and the center pillar as a whole can receive it. This is advantageous in terms of rigidity, and the number of spot welding spots is reduced, so that cost can be reduced.
