The utility model will be described in detail below with reference to the drawings in connection with embodiments.

Example 1

The present embodiment relates to a vehicle body rear structure, which is shown in connection with fig. 1 and 2, including a side body 1, and a rear body 2 connected to the rear portion of the side body 1. In this case, since the rear bumper 3 is generally provided at the rear part of the vehicle body, the rear wall 2 is located inside the rear bumper 3, that is, the rear bumper 3 faces the vehicle interior. Meanwhile, in the embodiment, a side wall bracket 6 is arranged at the tail part of the side wall 1, a rear wall bracket 5 is arranged on the rear wall 2, and the rear wall bracket 5 is provided with a connecting arm 501, and the connecting arm 501 is also connected with the side wall bracket 6.

At this time, in this embodiment, the connecting arm 501 is disposed on the rear wall bracket 5, and the connecting arm 501 is connected with the side wall bracket 6, so that the side wall bracket 6 and the rear wall bracket 5 are connected into a whole, so that the two can be mutually restricted, the rear wall bracket 5 can be prevented from sagging by using the support of the side wall bracket 6, and meanwhile, the side wall bracket 6 is prevented from warping by using the traction of the rear wall bracket 5.

In detail, however, since the side body 1 in the vehicle body generally includes the side body inner panel and the side body outer panel, the side body pillar 6 of the present embodiment may be disposed on the side body inner panel in the side body 1 and between the side body outer panel and the side body inner panel. The back wall support 5 may be set according to the structural configuration of the back wall 3, and when the back wall 3 includes a back wall inner plate and a back wall outer plate, the back wall support 3 may be generally set on the back wall outer plate.

In this embodiment, as a preferred implementation manner, the side wall bracket 6 and the rear wall bracket 5 may be injection molded, and when the side wall bracket 6 and the rear wall bracket 5 are both injection molded plastic parts, a plurality of reinforcing ribs are further provided on both sides, as shown in fig. 2. At this time, for convenience of description, the reinforcing ribs on the back wall bracket 5 are specifically the back wall bracket reinforcing ribs 502, and the reinforcing ribs on the side wall bracket 6 are specifically the side wall bracket reinforcing ribs 601. The back wall bracket reinforcing ribs 502 and the side wall bracket reinforcing ribs 601 are all arranged in a grid shape, and can have a good structural reinforcing effect.

It can be appreciated that the embodiment enables the side wall bracket 6 and the rear wall bracket 5 to be injection molded, which is convenient for the preparation of the side wall bracket 6 and the rear wall bracket 5, reduces the bracket cost and is beneficial to the weight reduction of the two brackets. Meanwhile, a plurality of reinforcing ribs are arranged on the side wall support 6 and the rear wall support 5, so that the structural strength of the two supports can be increased, and the use effect of the two supports can be guaranteed.

Of course, it should be noted that, instead of reinforcing ribs on both the side frame 6 and the rear frame 5, it is also possible to selectively provide reinforcing ribs on only one of the side frame 6 and the rear frame 5 according to the respective structures of the side frame 6 and the rear frame 5 and the strength requirements thereof. It should also be noted that, in addition to injection molding, the side wall brackets 6 and the rear wall brackets 5 may of course also be produced by means of, for example, casting, and may preferably be produced, for example, from cast aluminum, in order to likewise facilitate weight reduction of the two brackets.
