At this time, the cavity Q at the position of each first portion 401a may still be as shown in fig. 6, the cavity Q at the position of the second portion 401b may still be as shown in fig. 7, and the cavities Q at the two first portions 401a are communicated via the cavity Q at the second portion 401b.

It will be appreciated that by making the boss 401 "n" shaped and defined by the first portion 401a and the second portion 401b, it is possible to better increase the structural strength of the mounting plate 4 while facilitating the increase in rigidity of the rear shock absorber mounting point 4 a. However, it should be noted that, in the embodiment, it is also possible to make the boss 401 of the present embodiment only of two first portions 401a, except that it is preferable to make the boss 401 of the first portion 401a and the second portion 401b described above. At this time, the cavities Q at the two first portions 401a are also arranged side by side, and reinforcement of the rigidity of the rear damper mounting points 4a at the respective positions is achieved, respectively.

It should be noted that, similarly to the related structure in the existing vehicle, the rear wheel cover 2 of the present embodiment is also constituted by the rear wheel cover inner plate 201 and the rear wheel cover outer plate 202 that are connected together, and the connection between the rear wheel cover 2 and the vehicle body structures such as the rear floor side member 1 and the C pillar 3 is also made by referring to the related structure in the existing vehicle.

Further, as shown in fig. 8, the rear wheel house front reinforcement plate 5 of the present embodiment may also be a press-formed plate member, and it may be elongated and fixed to the rear wheel house inner plate 201. The bottom of reinforcing plate 5 before the rear wheel casing and the linking setting between mounting panel 4 to and the linking setting between reinforcing plate 5 top and the C post 3 before the rear wheel casing, its concrete is that the bottom of reinforcing plate 5 before the rear wheel casing overlaps at least partially with the projection of mounting panel 4 in the whole car left and right directions, and the projection of reinforcing plate 5 top and C post 3 in the whole car upper and lower direction before the rear wheel casing overlaps at least partially.

The projection overlap between the front reinforcing plate 5 of the rear wheel cover and the mounting plate 4 and the projection overlap between the front reinforcing plate 5 of the rear wheel cover and the C-pillar 3 may be just the projection overlap, but the two are not connected together, but can be connected together by direct connection or indirect connection except projection coincidence.

In particular, between the bottom of the front reinforcing plate 5 of the rear wheel cover and the mounting plate 4, for example, the bottom of the front reinforcing plate 5 of the rear wheel cover and the upper connection flange 402 on the top of the mounting plate 4 overlap, so that the front reinforcing plate 5 of the rear wheel cover and the mounting plate 4 are directly connected by welding. The top of the front reinforcing plate 5 of the rear wheel cover and the C column 3 can be welded in a multi-layer mode, so that the front reinforcing plate and the C column are indirectly connected through the rear wheel cover 3.

At this time, by providing the in-wheel-cover reinforcing plate 7 on the inner side of the rear wheel cover 3, it can be understood that it can further increase the rigidity of the position of the mounting plate 4 on the basis of the front reinforcing plate 5 of the rear wheel cover, and make the stress at the mounting plate 4 better transmit dispersion to the C-pillar 3.

In addition, the connection between the bottom of the reinforcing plate 7 in the wheel cover and the rear floor stringer 1 may be that the bottom of the reinforcing plate 7 in the wheel cover is overlapped on the top of the rear floor stringer 1 and is connected with the rear floor stringer 1 by welding. The connection between the bottom of the reinforcing plate 7 in the wheel cover and the mounting plate 4, and the connection between the top of the reinforcing plate 7 in the wheel cover and the C column 3, also refer to that the projections between the bottom of the reinforcing plate 7 in the wheel cover and the mounting plate 4 in the left and right directions of the whole vehicle are at least partially overlapped, and the projections between the top of the reinforcing plate 7 in the wheel cover and the C column 3 in the left and right directions of the whole vehicle are at least partially overlapped.

The projection overlap between the bottom of the reinforcing plate 7 in the wheel cover and the mounting plate 4, and between the top of the reinforcing plate 7 in the wheel cover and the C-pillar 3 may be just the projection overlap, but the projection overlap may not be the same, or may be a direct connection or an indirect connection.

In the embodiment, the bottom of the reinforcing plate 7 in the wheel cover and the mounting plate 4 may be indirectly connected by, for example, multi-layer welding, through the rear wheel cover inner plate 201, or the top of the reinforcing plate 7 in the wheel cover and the C pillar 3 may be indirectly connected by multi-layer welding, through the rear wheel cover inner plate 201.

It will be appreciated that having the wheel well inner reinforcement plate 7 specifically formed of the inner reinforcement plate upper plate 701 and the inner reinforcement plate lower plate 702 facilitates the shaping of the wheel well inner reinforcement plate 7 to reduce manufacturing costs. However, instead of being composed of the inner reinforcement plate upper plate 701 and the inner reinforcement plate lower plate 702, it is of course possible to embody such that the wheel house inner reinforcement plate 7 is made of a single sheet metal stamping.

In the present embodiment, as a preferable embodiment, a raised portion 701a is formed on the upper portion of the wheel house inner reinforcement plate 7, that is, the wheel house inner reinforcement plate 7 includes an inner reinforcement plate upper plate 701 and an inner reinforcement plate lower plate 702, as an example, on the inner reinforcement plate upper plate 701. The two raised parts 701a are specifically two raised parts arranged side by side, and the bottom ends of the two raised parts 701a are intersected together, and the top ends of the two raised parts 701a are all connected with the C column 3.

At this time, the engagement between the tips of the two ridge portions 701a and the C column 3 is the same as the engagement between the top of the reinforcing plate 7 and the C column 3 in the wheel house described above. It will be appreciated that by providing the raised portion 701a on the wheel cover inner plate reinforcing plate 7, it is obvious that the raised portion 701a may also form a cavity structure with the rear wheel cover inner plate 201, and further, the structural strength of the raised portion 701a may be increased, thereby increasing the structural reinforcing and force transmitting effects of the wheel cover inner plate 7.

As further shown in fig. 12, in this embodiment, as a preferred embodiment, the rear-wheel-cover front reinforcement plate 5 may be specifically located on the side of the rear wheel cover 2 facing the outside of the vehicle, and in the front-rear direction of the vehicle, the rear-wheel-cover front reinforcement plate 5 is disposed in engagement with the front side of the mounting plate 4, and the in-wheel-cover reinforcement plate 7 is disposed in engagement with the rear side of the mounting plate 4. At this time, the front reinforcing plate 5 of the rear wheel cover is positioned on the side of the rear wheel cover 2 facing the outside of the vehicle, and the front reinforcing plate 5 of the rear wheel cover is connected with the front side of the mounting plate 4, and the inner reinforcing plate 7 of the wheel cover is connected with the rear side of the mounting plate 4, so that the front reinforcing plate 5 of the rear wheel cover and the inner reinforcing plate 7 of the wheel cover can respectively reinforce the front and rear positions of the mounting plate 4, thereby better reinforcing effect can be obtained.

Further, as also shown in fig. 9, a rear floor upper cross member 8 connected to the rear floor side member 1 is also included in the vehicle body rear structure of the present embodiment, and the bottom end of the wheel house inner reinforcement 7 is also connected to this rear floor upper cross member 8. In this way, the bottom end of the in-wheel-cover reinforcing plate 7 is connected to the rear floor upper cross member 8, which obviously can further increase the rigidity of the rear damper mounting point 4a by means of the rear floor upper cross member 8. In the concrete implementation, the bottom end of the reinforcing plate 7 in the wheel cover extends to the upper part of the rear floor upper beam 8, and is connected with the rear floor upper beam 8 in a welding mode after being lapped on the rear floor upper beam 8.
