Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to the improvement of the rear body structure of an automobile, particularly the structure around the lamp housing section at the lower part of the rear pillar.

(Prior art) For example, as disclosed in Japanese Utility Model Application Publication No. 54-58711, a rear pillar extending in the vertical direction is installed at the corner between the rear fender and the park door at the rear of the vehicle body of a van or wagon type vehicle. will be provided. As shown in Fig. 1, the rear pillar A published in the above publication has a closed cross-sectional shape in order to ensure the strength of the corner part, but in order to attach a lamp to the lower part of the rear pillar A, An opening C for attaching a lamp is formed in the outer panel B at the lower part of the pillar. Therefore, there was a problem in that the formation of the opening C lowered the rigidity of the lower part of the pillar, resulting in insufficient strength in that part. If the lamp housing panel that houses the lamp protrudes significantly rearward due to the lamp shape, etc., and the inner panel that constitutes the rear pillar or the inner panel is joined to the reinforcement, the inner panel Also, the reinforcement requires an opening for accommodating the protrusion of the lamp housing, further reducing the rigidity or strength of the rear pillar.

(Purpose of the invention) The present invention addresses the above-mentioned problems regarding the rear body structure of an automobile.The lamp housing panel, on which the lamp is attached to the lower part of the rear pillar at the rear of the car body, is greatly curved rearward, and as a result, the inner panel and In a configuration in which the reinforcement joined to the panel is also provided with openings, the purpose is to prevent a decrease in rigidity or strength due to these openings and to ensure the required strength.

(Structure of the invention) That is, the present invention includes a rear pillar that is composed of an inner panel and an outer panel and extends in the vertical direction;
A rear body structure of an automobile, comprising: a reinforcement joined to the inner panel to form a closed cross section extending in the vertical direction; and a lamp housing panel provided at the lower part of the outer panel of the rear pillar and having an inwardly curved recess. , openings are formed in the inner panel and reinforcement at positions corresponding to the lamp housing panel, and the peripheral edges of the openings are joined to the lamp housing panel.

According to such a configuration, although the opening is provided in the reinforcement and the inner panel at the lower part of the rear pillar, the peripheral edge of the opening is joined to the lamp housing panel, so that the opening for mounting the lamp at the lower part of the rear pillar is joined to the lamp housing panel. The openings of the housing panel are all closed by the housing panel, and the vertically extending closed section formed by the inner panel and the reinforcement is completely closed. This improves the rigidity or strength of the lamp mounting portion at the bottom of the rear pillar.

(Example) Examples of the present invention will be described below.

As shown in FIG. 2, a rear pillar 4 is vertically provided at the corner between the rear fender 2 and the back door 3 at the rear of the vehicle body of the automobile 1.
A rear combination lamp 5 is attached to the lower part of the rear pillar 4. This rear pillar 4
As shown in FIG. 3, the rear outer panel (rear fender panel) 6 and the rear inner panel 7
and a reinforcement 8 joined to the inner panel 7.
A closed cross section 9 extending in the vertical direction is formed by the reinforcement 8 and the reinforcement 8 . Also, a mounting portion 10 for the lamp 5 at the lower part of the rear pillar 4 is provided.
As shown in FIGS. 4 and 5, a lamp mounting opening 6a for housing the lamp 5 is formed in the outer panel 6, and a lamp housing panel 11 is provided in the opening 6a. . The lamp housing panel 11 has a recess 11a that is largely curved inward according to the size and shape of the lamp 5, and a peripheral edge 11b is joined to a peripheral edge 6b of the opening 6a in the outer panel 6.

Furthermore, since the lamp housing panel 11 is largely curved inward, the inner panel 7 and reinforcement 8 that constitute the rear pillar 4 also correspond to the opening 6a of the outer panel 6 or the housing panel 11. Openings 7a and 8a are formed in this way. Since the peripheral edges 7b and 8b of both openings 7a and 8a are joined to the back surface of the lamp housing panel 11, the openings 7a and 8a are closed by the lamp housing panel 11, and
A closed section 9 formed by the inner panel 7 and the reinforcement 8 and extending in the vertical direction is completely closed and does not communicate with the outside.

According to the above-mentioned configuration, in the lamp mounting portion 10 at the lower part of the rear pillar 4, although the openings 7a, 8a are formed in the inner panel 7 and the reinforcement 8 of the pillar 4, the lamp housing panel 11 is utilized to close both the openings 7a, 8a, and completely close the closed cross section 9 formed by the inner panel 7 and the reinforcement 8 and extending in the vertical direction. Also, the lamp mounting opening 6a in the outer panel 6 is closed by the lamp housing panel 11, so that the openings 6a, 7a,
As a result, the reduction in rigidity or strength of the lamp mounting portion 10 at the bottom of the rear pillar caused by the provision of these openings 6a, 7a, 8a is prevented, and the required strength or rigidity is ensured.

(Effects of the invention) As described above, according to the invention, the rear pillar extending in the vertical direction at the rear of the vehicle body is made up of an inner panel and an outer panel, and a reinforcement is coupled to the inner panel, and the lamp of the outer panel In a rear body structure of an automobile in which a lamp housing panel is attached to a mounting opening, the opening of the outer panel and the reinforcement provided corresponding to the lamp housing panel and the opening of the inner panel are connected by the housing panel. The inner panel, reinforcement, and lamp housing panel completely close the closed section extending in the vertical direction, so that the lamp housing panel is used as a strength member. As a result, the rigidity or strength of the lamp mounting portion at the lower part of the rear pillar is improved.
