[0035] Reference below Figure 1-Figure 7 A body assembly 100 of a vehicle according to an embodiment of the present invention is described.

[0036] like Figure 1-Figure 7 As shown, the vehicle body assembly 100 according to the embodiment of the present invention includes: a longitudinal beam body 10 and a first reinforcement member 20 .

[0037] The longitudinal beam body 10 is connected to the rocker beam 40 of the vehicle; along the first direction (ie, Figure 1 The first reinforcement member 20 is provided at one end of the longitudinal beam body 10 close to the threshold beam 40. The first reinforcement member 20 includes: a first reinforcement body 21 and a first flange 22 connected along the second direction (i.e. Figure 1 The first flange 22 is sandwiched between the longitudinal beam body 10 and the sill beam 40, and the second direction of the body component 100 (ie Figure 1 The Y direction shown in FIG. 1 is in the first direction of the vehicle body component 100 (ie, Figure 1 The X direction shown is perpendicular to the

[0038] Among them, Figure 6 and Figure 7 As shown, the rocker beam 40 includes a rocker beam body and a rocker rear section 480, which is arranged along a first direction (ie, Figure 1 The sill beam body and the sill rear section 480 are connected and arranged, and the sill rear section 480 is located at the rear end of the sill beam body.

[0039] The longitudinal beam body 10 is disposed along a first direction (ie, Figure 1 The longitudinal beam body 10 is extended in the X direction as shown in the figure, and has two opposite ends. One end of the longitudinal beam body 10 close to the rear section 480 of the rocker is connected to the rear section 480 of the rocker.

[0040] Along the first direction (ie Figure 1 The first reinforcement 20 is disposed at one end of the longitudinal beam body 10 close to the door sill beam 40, that is, the first reinforcement 20 is disposed at the front end of the longitudinal beam body 10, and the first reinforcement 20 includes a first reinforcement body 21 and a first flange 22. The first reinforcement body 21 is disposed on the longitudinal beam body 10, and the first reinforcement body 21 and the longitudinal beam body 10 can be connected by but not limited to welding, screwing, etc.

[0041] The first reinforcing body 21 and the first flange 22 are connected and arranged. As some embodiments of the present application, the first reinforcing body 21 and the first flange 22 can be integrally formed, that is, the first reinforcing member 20 is an integrally formed member. Figure 1 The first flange 22 is sandwiched between the longitudinal beam body 10 and the sill beam 40. Specifically, the first flange 22 is sandwiched between the longitudinal beam body 10 and the sill rear section 480 of the sill beam 40. As some embodiments of the present application, along the second direction (i.e. Figure 1 The Y direction shown in the figure) and from the outer side of the vehicle to the inner side of the vehicle, the rocker rear section 480, the first flange 22, and the longitudinal beam body 10 are arranged in sequence.

[0043] It should be noted that the end of the longitudinal beam body 10 close to the sill beam 40 can be used as the mounting point of the vehicle rear suspension. For example, the end of the longitudinal beam body 10 close to the sill beam 40 can be used as the mounting point of the vehicle rear suspension trailing arm. By providing the first reinforcement 20 at the end of the longitudinal beam body 10 close to the sill beam 40, the dynamic stiffness of the vehicle rear suspension mounting point can be improved. In addition, by clamping the first flange 22 between the longitudinal beam body 10 and the sill rear section 480 of the sill beam 40, the relative positioning of the longitudinal beam body 10, the sill rear section 480 and the first reinforcement 20 can be reasonable, which can effectively improve the dynamic stiffness of the vehicle rear suspension mounting point.

[0044] As some embodiments of the present application, the number of the longitudinal beam bodies 10 can be set to two, the number of the sill beams 40 can be set to two, and the second direction (ie, Figure 1 In the Y direction shown in the figure, the two longitudinal beam bodies 10 can be arranged opposite to each other and spaced apart, the two sill beams 40 can be arranged opposite to each other and spaced apart, and the two longitudinal beam bodies 10 and the two sill beams 40 can be arranged one by one, and each longitudinal beam body 10 can be provided with a first reinforcement member 20.

[0087] Along the first direction of the vehicle body assembly 100 (i.e., Figure 1 the X direction shown), the sixth reinforcing member 72 is disposed between the fourth reinforcing member 70 and the fifth reinforcing member 71, and the sixth reinforcing member 72 is spaced apart from both the fourth reinforcing member 70 and the fifth reinforcing member 71. That is to say, the sixth reinforcing member 72 is located on the side of the fourth reinforcing member 70 away from the first reinforcing member 20, and the sixth reinforcing member 72 is located on the side of the fifth reinforcing member 71 close to the first reinforcing member 20.

[0088] As some embodiments of the present application, the sixth reinforcing member 72 is adapted to correspond to the vehicle rear suspension spring.

[0089] By providing the sixth reinforcing member 72, the structural strength of the longitudinal beam body 10 can be improved, and the dynamic stiffness of the vehicle rear suspension mounting point can be increased. Moreover, by making the sixth reinforcing member 72 correspond to the vehicle rear suspension spring, it is beneficial to ensure the stiffness of the vehicle rear suspension spring mounting point.

[0090] As some embodiments of the present application, both the fourth reinforcing member 70 and the fifth reinforcing member 71 can be configured as a structure similar to a "Ji" shape.

[0091] As some embodiments of the present application, any two of the height direction of the vehicle body assembly 100 (i.e., Figure 1 the Z direction shown), the first direction of the vehicle body assembly 100 (i.e., Figure 1 the X direction shown), and the second direction of the vehicle body assembly 100 (i.e., Figure 1 the Y direction shown) are perpendicular to each other.

[0092] According to the vehicle of the embodiment of the present invention, including the vehicle body assembly 100 of the above embodiment, by providing the first reinforcing member 20 at one end of the longitudinal beam body 10 close to the sill beam 40, and by sandwiching the first flange 22 between the longitudinal beam body 10 and the sill beam 40, the dynamic stiffness of the vehicle rear suspension mounting point can be increased, the structural design of the vehicle body assembly 100 can be made reasonable, which is beneficial to improving the NVH performance of the vehicle, and thus the driving experience and riding experience of the vehicle can be improved.
