This arrangement can form two groups of force transmission paths between the vehicle body 1 and the battery pack, one group of which is transmitted from the front end of the vehicle body 1 along the rocker beam 4 to the rear end of the vehicle body 1, and the other group of which is transmitted from the front end of the vehicle body 1 along the path of the battery pack and the first side mounting point 41, the second side mounting point 42, the third side mounting point 43 and the fourth side mounting point 44 to the rear end of the vehicle body 1, thereby improving the safety performance of the vehicle body 1 in side collision, and then improving the safety performance of the vehicle.

[0030] Therefore, by defining the installation space of the battery pack by the front beam structure 2, the rear beam structure 3 and the door sill beam 4, it is convenient to install the battery pack on the vehicle body 1, and the first side mounting point 41, the second side mounting point 42, the third side mounting point 43 and the fourth side mounting point 44 are arranged at intervals in the front-to-rear direction of the door sill beam 4, and the B-pillar inner panel 5 is located between the second side mounting point 42 and the third side mounting point 43, so that the side collision safety performance of the vehicle body 1 can be improved, and then the safety performance of the vehicle can be improved.

[0031] Among them, Figure 1 and Figure 3As shown, the front beam structure 2 includes: a front cabin longitudinal beam 21, a torque box 22 and a middle channel 23 opposite to each other in the left and right directions, each front cabin longitudinal beam 21 is connected to a torque box 22, and the middle channel 23 is connected to the torque boxes 22 on both sides; wherein each torque box 22 is provided with a front mounting point for mounting the battery pack. That is to say, the front engine room longitudinal beam 21, the torsion box 22 and the middle channel 23 constitute the front beam structure 2, the front engine room longitudinal beam 21 is arranged on the vehicle body 1 at intervals on the left and right, the two torsion boxes 22 are located between the door sill beams 4, the two torsion boxes 22 limit the front engine room longitudinal beam 21, and each front engine room longitudinal beam 21 and the torsion box 22 correspond one to one, so that the front engine room longitudinal beam 21 is arranged on the torsion box 22, and the left and right sides of the middle channel 23 are respectively connected to the two adjacent ends of the two torsion boxes 22, so that the front engine room longitudinal beam 21, the torsion box 22 and the middle channel 23 can be connected, thereby improving the structural strength of the vehicle body 1, and each torsion and upper front mounting point are arranged, thereby facilitating the front side of the battery pack to be arranged on the front mounting point, thereby facilitating the connection between the battery pack and the torsion box 22, thereby improving the safety performance of the battery pack in frontal collision and the torsional stiffness of the vehicle.

[0032] In particular, if Figure 1 As shown, each torsion box 22 is provided with a first front mounting point 24 and a second front mounting point 25 spaced apart in the left-right direction, the first front mounting point 24 is located below the rear end of the front cabin longitudinal beam 21, and the second front mounting point 25 is located on the side of the first front mounting point 24 close to the longitudinal center line of the vehicle body 1. It can be understood that each torsion box 22 is provided with two front mounting points, so that the front side of the battery pack can be connected to the torsion box 22 through four front mounting points, the first front mounting point 24 and the second front mounting point 25 are spaced apart in the left-right direction of the torsion box 22, and the first front mounting point 24 is located below the rear end of the front cabin longitudinal beam 21, so that the front cabin beam, the torsion box 22 and the battery pack can be connected, and the second front mounting point 25 on each torsion box 22 is close to each other, so that the second front mounting point 25 can be close to the longitudinal center line of the vehicle body 1, thereby improving the safety performance of the battery pack in frontal collision, and further improving the torsional stiffness and safety performance of the vehicle.

[0033] In addition, if Figure 5As shown, the front beam structure 2 further includes: a reinforcing plate 26, which is arranged in the middle channel 23, and the torsion box 22 is provided with a support leg extending backward, which is connected to the reinforcing plate 26. In other words, the reinforcing plate 26 is arranged on one side of the middle channel 23, so that the structural strength of the middle channel 23 can be improved, and the support leg is arranged on the rear side of the torsion box 22, and the support leg is connected to the front side of the reinforcing plate 26.

[0035] In particular, if Figure 1 and Figure 4 As shown, the minimum lateral distance between any one of the second mounting point and the third mounting point and the reinforcing plate 26 is L, and L satisfies the relationship: L≤50mm. In other words, the minimum lateral distance between the second mounting point and the left side of the reinforcing plate 26 must be within a reasonable range, and the minimum lateral distance between the third mounting point and the right side of the reinforcing plate 26 must be within a reasonable range. If the minimum lateral distance between the second mounting point and the left side of the reinforcing plate 26 and the minimum lateral distance between the third mounting point and the right side of the reinforcing plate 26 are greater than 50mm, this will cause the torsional stiffness between the rear side of the battery pack and the middle floor crossbeam 31 to fail to meet the safety standard, thereby causing the vehicle safety performance to decline, and further endangering the lives of passengers.

[0036] In addition, if Figure 1 and Figure 4 As shown, the lateral distance from the center of the first rear mounting point 33 to the longitudinally extending centerline of the rear floor longitudinal beam 32 on the corresponding side is a, and the lateral distance from the center of the first rear mounting point 33 to the longitudinally extending centerline of the vehicle body 1 is b, a=b; the lateral distance from the center of the fourth rear mounting point 36 to the longitudinally extending centerline of the rear floor longitudinal beam 32 on the corresponding side is c, and the lateral distance from the center of the fourth rear mounting point 36 to the longitudinally extending centerline of the vehicle body 1 is d, c=d. It can be understood that the first rear mounting point 33 is located in the middle position between the longitudinally extending centerline of the vehicle body 1 and the longitudinally extending centerline of the left rear floor longitudinal beam 32, and the fourth rear mounting point 36 is located in the middle position between the longitudinally extending centerline of the vehicle body 1 and the longitudinally extending centerline of the right rear floor longitudinal beam 32, so that the torsional rigidity of the vehicle body 1 can be improved, and then the safety performance of the vehicle can be improved.

[0037] In addition, Figure 4 and Figure 5 As shown, the middle floor cross beam 31 is provided with a first bracket 311 corresponding to the first rear mounting point 33, a second bracket 312 corresponding to the second rear mounting point 34, a third bracket 313 corresponding to the third rear mounting point 35 and a fourth bracket 314 corresponding to the fourth rear mounting point 36, and the rear floor longitudinal beam 32 is provided with a fifth bracket 315 corresponding to the fifth rear mounting point 37.
