[0024] The following describes in detail embodiments of the present application. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application.

[0025] Reference below Figures 1-3 A body assembly 100 for a vehicle according to an embodiment of the present application is described. The body assembly 100 includes a body 110, a longitudinal beam 120, a wheel cover 130 and a connection box 140. The longitudinal beam 120 is connected to the body 110, and a first connection portion 121 is formed at one end of the longitudinal beam 120. The wheel cover 130 is connected to the body 110, and a second connection portion 131 is formed at one end of the wheel cover 130. An energy absorption cavity 141 is formed in the connection box 140, and the connection box 140 is respectively connected to the first connection portion 121 and the second connection portion 131.

[0026] In related technologies, during a side-on frontal collision, the impact force generated by the collision is only transmitted through the front wheel arch side reinforcement beam, and the front longitudinal beam of the vehicle body cannot share the impact force and absorb the energy, resulting in excessive intrusion of the vehicle's front fender during a frontal collision, increased deformation of the passenger compartment, and greater damage to passengers.

[0027] Specifically, if Figure 1 and Figure 2 As shown, the longitudinal beam 120 and the wheel cover 130 are respectively connected to the vehicle body 110, wherein the longitudinal beam 120 and the wheel cover 130 can be fixedly connected to the vehicle body 110 by welding to improve the structural strength between the longitudinal beam 120 and the wheel cover 130 and the vehicle body 110, the longitudinal beam 120 and the wheel cover 130 can respectively extend in the direction of travel of the vehicle, and the longitudinal beam 120 and the wheel cover 130 can respectively be connected to the connecting box 140, thereby forming a complete force transmission structure.

[0028] Furthermore, a first connection portion 121 may be formed at one end of the longitudinal beam 120, and the other end of the longitudinal beam 120 may be connected to the vehicle body 110. A second connection portion 131 may be formed at one end of the wheel cover 130, and the other end of the wheel cover 130 may be connected to the vehicle body 110. The connection box 140 may be connected to the first connection portion 121 and the second connection portion 131, respectively. Optionally, the connection box 140 and the first connection portion 121 may be detachably connected by bolts and threads, or the connection box 140 and the first connection portion 121 may be detachably connected by snapping or plugging, or the contact surfaces between the connection box 140 and the first connection portion 121 may be directly welded. Similarly, the connection box 140 and the second connection portion 131 may be detachably connected by bolts and threads, or the connection box 140 and the second connection portion 131 may be detachably connected by snapping or plugging, or the connection box 140 and the second connection portion 131 may be directly welded.

[0029] like Figure 2 As shown, the connection box 140 can be a box body structure, and an energy absorption cavity 141 can be formed in the connection box 140. The energy absorption cavity 141 can reduce the overall weight of the connection box 140 and realize a lightweight setting of the connection box 140. At the same time, the energy absorption cavity 141 can also absorb part of the energy generated by the collision.

[0030] Specifically, the connection box 140 absorbs some of the impact force generated by the collision by collapsing. Connected to the first connection portion 121 and the second connection portion 131, the connection box 140 guides the collision force, which can be directed through the connection box 140 to the longitudinal beam 120 and wheel arch 130. This effectively disperses the impact force, reduces the amount of intrusion into the vehicle's front fender during a frontal collision, and consequently minimizes deformation of the passenger compartment, ensuring passenger safety.

[0031] It can be seen that when the vehicle collides head-on or sideways, the energy generated by the collision is first transmitted to the connecting box 140, and then transmitted to the longitudinal beam 120 and the wheel cover 130 respectively through the connecting box 140, so that the longitudinal beam 120 can effectively absorb energy during the collision, reducing the damage caused by the head-on or side collision of the vehicle.

[0032] In short, the body assembly 100 of the present application is provided with a connection box 140, which is respectively connected to the longitudinal beam 120 and the wheel cover 130. When the vehicle collides head-on or side-on, the connection box 140 can absorb part of the energy generated by the collision while transferring the energy to the longitudinal beam 120 and the wheel cover 130 respectively, thereby effectively dispersing the energy generated by the collision, further reducing the deformation of the passenger compartment, reducing the damage to passengers in the event of a head-on or side-on collision, and improving the safety performance of the vehicle.

[0033] like Figure 1 and Figure 2 As shown, in some embodiments of the present application, a first mounting groove 122 may be formed on the first connecting portion 121, and a second mounting groove 132 may be formed on the second connecting portion 131, and both ends of the connecting box 140 in the extension direction may be accommodated in the first mounting groove 122 and the second mounting groove 132, wherein the extension direction of the connecting box 140 may be the width direction of the vehicle, and the outer wall of the connecting box 140 may be fitted with the inner wall of the first mounting groove 122 and the second mounting groove 132.

[0034] like Figure 2As shown, in some embodiments of the present application, the first mounting groove 122 and the second mounting groove 132 can be open toward each other. It can be understood that the opening direction of the first mounting groove 122 can be opposite to the opening direction of the second mounting groove 132, so that the connection box 140 can be located between the first connection part 121 and the second connection part 131.

It is understandable that the depth of the first mounting groove 122 can gradually increase or decrease in the width direction of the vehicle. By setting the first mounting groove 122 in the above-mentioned structure, one end of the first mounting groove 122 can be stopped against one side of the connection box 140. At the same time, the connection box 140 can transmit energy more efficiently. Similarly, the structure of the second mounting groove 132 can be the same as that of the first mounting groove 122.
