[0039] Unless otherwise stated, the numerical ranges herein include not only the entire range within its two endpoints but also include several sub-ranges contained therein.
[0040] Figures 1 to 5 It is shown that a vehicle body according to the present invention is provided with a wishbone mounting seat 130 and a subframe mounting seat 140 , and the projection of the wishbone mounting seat 130 along the height direction Z of the vehicle at least partially overlaps with the projection of the subframe mounting seat 140 along the height direction Z.
[0041] According to the vehicle body of the present invention, the projection of the subframe mounting seat 140 provided on the vehicle body along the height direction Z at least partially overlaps with the projection of the fork arm mounting seat 130 along the height direction Z, so that the subframe is connected to the vehicle body at a position corresponding to the fork arm along the vehicle length direction X and the width direction Y, so that the subframe participates in the path of transmission from the suspension assembly to the vehicle body, and also enables the suspension to effectively transmit force to the vehicle body when moving, thereby enhancing the dynamic stiffness of the suspension assembly and improving the structural strength of the vehicle body.
[0042] Figure 1 The length direction X, width direction Y and height direction Z of the vehicle are shown. Figure 1 It can be seen that the vehicle body structure forms a front cabin, and the inner wall of the front cabin is the front cabin inner wall 100. The front cabin inner wall 100 generally extends along the width direction Y and is perpendicular to the length direction X, thereby serving as a barrier between the front cabin and the interior space of the vehicle. The vehicle body also includes two front longitudinal beams 110 and two wheel housings 120. The front longitudinal beams 110 extend along the length direction X and protrude from the front cabin, and the two front longitudinal beams 110 are arranged and spaced apart along the width direction Y.
[0043] Reference Figure 1 The wheel cover 120 is arranged on the side of the front compartment inner wall 100 close to the front of the vehicle. The wheel cover 120 is connected to the front longitudinal beam 110, and the two wheel covers 120 are respectively connected to the two front longitudinal beams 110. The wheel cover 120 provides a storage space for the wheels and suspension assembly of the vehicle. The fork arm mounting seat 130 is arranged on the inner side of the wheel cover 120, and the subframe mounting seat 140 is arranged on the front longitudinal beam 110. The suspension assembly includes a fork arm and a lower arm. The fork arm is connected to the fork arm mounting seat 130, and the lower arm is connected to the subframe. The subframe is also connected to the vehicle body through the front longitudinal beam 110, so that the force of the suspension assembly can also be transmitted to the vehicle body through the subframe, so that the suspension assembly and the vehicle body have a stable connection, which improves the dynamic stiffness of the suspension assembly.
[0044] Reference Figure 2The fork arm mounting seat 130 includes a mounting upright plate 131, and the mounting upright plate 131 and the wheel cover 120 are configured to form a fork arm mounting cavity 133, and the fork arm mounting cavity 133 is suitable for connecting the fork arm. The fork arm mounting seat 130 and the wheel cover 120 are configured to form the fork arm mounting cavity 133, so that part of the 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 the force is directly transmitted to the wheel cover 120, so as to disperse the transmission path of the force transmitted from the fork arm to the wheel cover 120, prevent the force of the fork arm from being concentrated in a local position of the wheel cover 120, further improve the connection strength between the fork arm and the wheel cover 120, and improve the dynamic stiffness of the suspension assembly.
[0045] Optionally, the wheel cover 120 is at least partially connected to the side of the front longitudinal beam 110 close to the vehicle passenger compartment along the width direction Y of the vehicle, so that the wheel cover 120 and the front longitudinal beam 110 are connected in both the height direction Z and the width direction Y, and the connection is more stable.
[0046] In detail, the wheel cover 120 includes a connecting portion 123, which is connected to a side wall of the front longitudinal beam 110 close to the vehicle passenger compartment along the width direction Y and is flush with the side wall of the front longitudinal beam 110 on this side, so that the wheel cover 120 is connected to the front longitudinal beam 110. Since the connecting portion 123 protrudes from the front longitudinal beam 110 along the width direction Y, a turning moment in the horizontal direction (length direction X and width direction Y) is formed between the connecting portion 123 and the front longitudinal beam 110. Therefore, the flush setting of the connecting portion 123 with the side wall of the front longitudinal beam 110 can reduce the turning moment between the front longitudinal beam 110 and the wheel cover 120, reduce the wear between the wheel cover 120 and the front longitudinal beam 110, and make the connection between the wheel cover 120 and the front longitudinal beam 110 more stable.
[0047] Furthermore, the front longitudinal beam 110 is provided with a connecting groove 112, and the connecting portion 123 is arranged in the connecting groove 112, and the connecting portion 123 is flush with the side wall of the connecting groove 112 of the front longitudinal beam 110, so that the connecting portion 123 of the wheel cover 120 and the front longitudinal beam 110 have a sufficient connection area, thereby ensuring the connection strength between the wheel cover 120 and the front longitudinal beam 110.
[0048] Optionally, the fork arm mounting seat 130 at least partially overlaps with the connecting portion 123 along the length direction X. In other words, along the length direction X, the connecting portion 123 and the fork arm mounting seat 130 have an overlapping portion, so that the spacing between the fork arm mounting seat 130 and the connecting portion 123 is as small as possible, thereby reducing the turning moment on the fork arm mounting seat 130, and making the connection between the fork arm and the wheel cover 120 more stable.
[0049] Further, see Figure 2The fork arm mounting seat 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 arranged in parallel with the mounting vertical plate 131 and is spaced apart along the length direction X. The fork arm is connected between the wheel cover side plate 122 and the mounting vertical plate 131 through a pin shaft to achieve the connection between the fork arm and the wheel cover 120. The wheel cover inner plate 121 is respectively configured with the mounting vertical plate 131, the wheel cover side plate 122 and the first reinforcing plate 132 to form a fork arm mounting cavity 133, thereby strengthening the connection of the fork arm and protecting the connection between the fork arm and the wheel cover 120.
[0050] Reference Figure 4 and Figure 5 The subframe mounting seat 140 includes a second reinforcing plate 141, which is connected to the front longitudinal beam 110. The projection of the second reinforcing plate 141 along the height direction Z at least partially overlaps with the projection of the fork arm mounting seat 130 along the height direction Z, so that the force arm between the second reinforcing plate 141 of the subframe mounting seat 140 that mainly bears the stress and the fork arm mounting seat 130 is small, thereby reducing the overturning moment between the fork arm and the lower swing arm, making the connection between the suspension assembly and the vehicle body more stable.
[0051] Reference Figure 5 The sub-frame mounting seat 140 further includes a front sealing plate 142, a sub-frame support plate 143 and a bolt sleeve 144. The front sealing plate 142, the second reinforcing plate 141 and the sub-frame support plate 143 are connected together to form a support cavity 145 suitable for accommodating the bolt sleeve 144. The bolt sleeve 144 is suitable for being connected to the sub-frame through a fastener. The provision of the bolt sleeve 144 enables the sub-frame mounting seat 140 to be firmly connected to the sub-frame through the fastener. In addition, the bolt sleeve 144 is accommodated in the support cavity 145, which has good protection performance and a compact structure.
[0052] Optionally, at least part of the sub-frame mounting seats 140 protrude from the side of the front longitudinal beam 110 along the width direction Y of the vehicle away from the vehicle passenger compartment along the width direction Y, so that the spacing between the sub-frame mounting seats 140 on the two front longitudinal beams 110 along the width direction Y is greater than the spacing between the front longitudinal beams 110 along the width direction Y, which can increase the force transmission area when the vehicle body transmits force along the length direction X, thereby improving the structural strength of the vehicle body.
[0053] The utility model also provides a vehicle, comprising the above-mentioned vehicle body. According to the vehicle of the utility model, the vehicle body has high structural strength and improves the dynamic stiffness of the suspension assembly connected to the vehicle body.
