According to the vehicle body, the projection of the auxiliary frame mounting seat 140 along the height direction Z and the projection of the fork arm mounting seat 130 along the height direction Z are at least partially overlapped, so that the auxiliary frame is connected with the vehicle body at the positions corresponding to the fork arms along the length direction X and the width direction Y of the vehicle, the auxiliary frame participates in the path of the suspension assembly transmitted to the vehicle body, the force can be effectively transmitted to the vehicle body during the suspension movement, the dynamic rigidity of the suspension assembly is enhanced, and the structural strength of the vehicle body is also improved.

Fig. 1 shows a longitudinal direction X, a width direction Y, and a height direction Z of a vehicle, and as can be seen from fig. 1, the vehicle body structure forms a front cabin, the inner wall of which is a front cabin inner wall 100, and the front cabin inner wall 100 exhibits a substantially longitudinal direction X extending in the width direction Y as a barrier to the front cabin and the vehicle interior space. The vehicle body further includes two front side members 110 and two wheel covers 120. The front side members 110 extend in the length direction X and protrude from the front cabin, and the two front side members 110 are arranged and spaced apart in the width direction Y.

Referring to fig. 1, a wheel cover 120 is provided at one side of the front cabin inner wall 100 near the vehicle head, the wheel cover 120 has a connection with the front side members 110, and the two wheel covers 120 are respectively connected to the two front side members 110. The wheel cover 120 provides a receiving space for the wheel and suspension assembly of the vehicle. The fork arm mount 130 is provided inside the wheel cover 120, and the subframe mount 140 is provided on the front side member 110. The suspension assembly comprises a fork arm and a lower swing arm, the fork arm is connected to a fork arm mounting seat 130, the lower swing arm is connected to the auxiliary frame, and the auxiliary frame is further connected with the vehicle body through the front longitudinal beam 110, so that the force of the suspension assembly can be transmitted to the vehicle body through the auxiliary frame, the suspension assembly and the vehicle body are stably connected, and the dynamic stiffness of the suspension assembly is improved.

Referring to fig. 2, the fork arm mount 130 includes a mounting riser 131, the mounting riser 131 and the wheel housing 120 being configured to form a fork arm mounting cavity 133, the fork arm mounting cavity 133 being adapted to connect a fork arm. The fork arm mounting seat 130 and the wheel cover 120 are configured to form a fork arm mounting cavity 133, so that part of force of the fork arm can be transmitted to the wheel cover 120 through the fork arm mounting seat 130, and the other part of force can be directly transmitted to the wheel cover 120, thereby facilitating the transmission path of the force transmitted to the wheel cover 120 by the dispersed fork arm, preventing the force of the fork arm from being concentrated at a local position of the wheel cover 120, further improving the connection strength between the fork arm and the wheel cover 120, and improving the dynamic stiffness of the suspension assembly.

Alternatively, the wheel cover 120 is at least partially connected to a side of the front side member 110 that is closer to the vehicle passenger compartment in the vehicle width direction Y, so that there is a connection between the wheel cover 120 and the front side member 110 in both the height direction Z and the width direction Y, which is more secure.

In detail, the wheel cover 120 includes a connecting portion 123, and the connecting portion 123 is connected to a side wall of the front side member 110 that is closer to the vehicle passenger compartment in the width direction Y and is flush with the side wall of the front side member 110, so that the wheel cover 120 and the front side member 110 are connected. Since the connecting portion 123 protrudes from the front side member 110 in the width direction Y, a turning moment in the horizontal direction (the length direction X and the width direction Y) is formed between the connecting portion 123 and the front side member 110, so that the connecting portion 123 is disposed flush with the side wall of the front side member 110, the turning moment between the front side member 110 and the wheel cover 120 can be reduced, wear between the wheel cover 120 and the front side member 110 is reduced, and the connection between the wheel cover 120 and the front side member 110 is made more stable.

Further, the front side member 110 is provided with the connecting groove 112, the connecting portion 123 is disposed in the connecting groove 112, and the connecting portion 123 is flush with the side wall of the connecting groove 112 where the front side member 110 is disposed, so that the connecting portion 123 of the wheel cover 120 and the front side member 110 have a sufficient connecting area, and the connecting strength of the wheel cover 120 and the front side member 110 is ensured.

Optionally, the yoke mount 130 at least partially overlaps the connection 123 along the length direction X. In other words, along the length direction X, the connecting portion 123 and the yoke mounting seat 130 have overlapping portions, so that the space between the yoke mounting seat 130 and the connecting portion 123 is as small as possible, and thus the overturning moment applied to the yoke mounting seat 130 can be reduced, and the connection between the yoke and the wheel cover 120 is more stable.

Further, referring to fig. 2, the yoke mount 130 further includes a first reinforcing plate 132, and the wheel cover 120 includes a wheel cover side plate 122 and a wheel cover inner plate 121, and the wheel cover side plate 122 is disposed parallel to the mounting riser 131 and spaced apart in the length direction X. The fork arms are connected between the wheel cover side plates 122 and the mounting vertical plates 131 through pin shafts, so that the connection between the fork arms and the wheel cover 120 is realized. The wheel cover inner plate 121 is configured with the mounting riser 131, the wheel cover side plate 122, and the first reinforcing plate 132, respectively, to form a fork arm mounting cavity 133, thereby reinforcing the connection of the fork arms and protecting the connection of the fork arms and the wheel cover 120.

Referring to fig. 4 and 5, the subframe mount 140 includes a second reinforcement plate 141, the second reinforcement plate 141 is connected to the front side member 110, and a projection of the second reinforcement plate 141 in the height direction Z at least partially overlaps a projection of the yoke mount 130 in the height direction Z, so that a moment arm between the second reinforcement plate 141, which mainly carries stress, of the subframe mount 140 and the yoke mount 130 is small, thereby reducing a turning moment between the yoke and the lower swing arm, and making a connection between the suspension assembly and the vehicle body more stable.

Referring to fig. 5, the subframe mount 140 further includes a front sealing plate 142, a subframe support plate 143, and a bolt housing 144, and the front sealing plate 142, the second reinforcing plate 141, and the subframe support plate 143 are connected together and configured to form a support cavity 145 adapted to receive the bolt housing 144, and the bolt housing 144 is adapted to be connected to the subframe by a fastener. The arrangement of the bolt sleeve 144 is adopted, so that the auxiliary frame mounting seat 140 and the auxiliary frame can be firmly connected through a fastener. In addition, the bolt sleeve 144 is accommodated in the supporting cavity 145, so that the protection performance is good, and the structure is compact.

Optionally, at least part of the subframe mounting seats 140 protrude from one side of the front longitudinal beam 110 away from the passenger compartment of the vehicle in the width direction Y of the vehicle, so that the distance between the subframe mounting seats 140 on the two front longitudinal beams 110 in the width direction Y is greater than the distance between the front longitudinal beams 110 in the width direction Y, which can increase the force transmission area of the vehicle body when the force is transmitted in the length direction X, and improve the structural strength of the vehicle body.

The utility model further provides a vehicle, which comprises the vehicle body. According to the vehicle provided by the utility model, the structural strength of the vehicle body is high, and the dynamic stiffness of the suspension assembly connected with the vehicle body is improved.
