[0061] In addition, if Fig. 9 and Fig.10 As shown, a third cavity 43 extending along the length direction of the front floor reinforcement plate 62 is defined between the front floor reinforcement plate 62 and the front floor panel 61, and the second cavity 42 and the third cavity 43 are opposite to each other in the front-to-rear direction, so that the front longitudinal beam 50 and the front panel 10 can form a continuous force transmission structure with the front floor reinforcement plate 62 and the front floor panel 61, that is, the second cavity 42 and the third cavity 43 can form a force transmission channel, thereby enhancing the impact resistance of the bottom of the vehicle body 100, optimizing the NVH performance of the vehicle body 100, and effectively improving the ride comfort. At the same time, when the vehicle body 100 collides, it can effectively transmit the force backward, resist deformation, reduce the intrusion amount, and ensure driving safety.

[0062] In some embodiments, the front floor panel 61 is welded to the front floor reinforcement plate 62 to ensure the connection reliability between the front floor panel 61 and the front floor reinforcement plate 62, facilitate processing and manufacturing, and reduce production costs.

[0065] According to some embodiments of the utility model, the rear end of the front longitudinal beam 50, the front floor panel 61 and the front floor reinforcement plate 62 are welded and connected to ensure that the rear end of the front longitudinal beam 50, the front floor panel 61 and the front floor reinforcement plate 62 are reliably connected and three-layer welding can be achieved, thereby ensuring the strength and sealing of the connection, and further improving the overall rigidity and durability of the vehicle body 100.

[0066] According to some embodiments of the present invention, Figure 7 As shown, the front longitudinal beam 50 has a width direction (eg Figure 7 A second avoidance groove 51 is provided on both sides of the front floor panel 61 (left and right directions shown in the figure), a first extension portion 611 is provided on the front side of the front floor reinforcement plate 62, a second extension portion 621 is provided on the front side of the front floor reinforcement plate 62, the first extension portion 611 and the second extension portion 621 are connected, and the first extension portion 611 and the second extension portion 621 are opposite to the second avoidance groove 51, which is convenient for the connection between the first extension portion 611, the second extension portion 621 and the front panel 10. The connection between the first extension portion 611, the second extension portion 621 and the front panel 10 can be avoided through the second avoidance groove 51, ensuring that the first extension portion 611, the second extension portion 621 are reliably connected to the front panel 10, so that the bottom structure of the vehicle body 100 is more compact.

[0067] In some embodiments of the utility model, the rear end of the front panel 10, the first extension portion 611 and the second extension portion 621 are welded and connected to ensure that the rear end of the front panel 10, the first extension portion 611 and the second extension portion 621 are reliably connected and three-layer welding can be achieved, thereby ensuring the strength and sealing of the connection and further improving the overall rigidity and durability of the vehicle body 100.

The steel dash panel 10 has good structural strength, can meet the structural strength requirements of the dash panel 10 , ensure the structural stability of the dash panel 10 , and thus can improve the structural strength of the vehicle body 100 .

[0082] The vehicle according to the embodiment of the utility model includes the vehicle body 100 according to the embodiment of the utility model. Since the vehicle body 100 according to the embodiment of the utility model has the above-mentioned beneficial technical effects, the vehicle according to the embodiment of the utility model is provided with an A-pillar inner panel 30 on both sides of the length direction of the A-pillar inner panel 30, and the A-pillar inner panel 30 is connected to the A-pillar inner panel 30 and the A-pillar inner panel 30 on the same side of the A-pillar inner panel 30, so that the A-pillar inner panel 30 and the A-pillar inner panel 30 on the same side of the A-pillar inner panel 30 can be formed. The cross beam 20 and the A-pillar inner panel 30 on the same side form a stable triangular support structure, ensuring reliable connection, being able to resist deformation and reduce intrusion during collision, thereby enhancing the rigidity and collision resistance of the front part of the vehicle body 100, effectively improving the small offset collision performance, MPDB collision performance and stability, improving the rigidity and NVH performance of the front part of the vehicle body 100, and solving the problems of large number of parts, complex structural processability, and poor water tightness of the passenger compartment, which is beneficial to improving the structure's ability to resist deformation and facilitating reducing the weight of the vehicle and production costs.

[0083] In some embodiments, when the vehicle is a hybrid model or a pure electric model, in order to increase the cruising range, it is necessary to increase the size of the vehicle's battery pack, thereby encroaching on the longitudinal beam structure space of the vehicle body 100, which conflicts with the vehicle's collision safety performance and cannot meet the small offset collision performance and MPDB collision performance.

[0084] Therefore, in the present invention, a first cavity 41 is defined between the front wall panel 10, the front wall cross beam 20 and the inner panel 30 of the A-pillar on the same side, the front longitudinal beam 50 and the front wall panel 10 are connected and define a second cavity 42 extending along the length direction of the front longitudinal beam 50, and a third cavity 43 extending along the length direction of the front floor reinforcement plate 62 is defined between the front floor reinforcement plate 62 and the front floor panel 61, and the second cavity 42 and the third cavity 43 are opposite in the front-to-back direction. Thus, deformation can be resisted and the intrusion amount can be reduced during a collision, and the problem of insufficient ability of the vehicle body 100 to resist collision deformation caused by the lack of a longitudinal beam rear section is solved, and collision energy is effectively absorbed, and the rigidity and anti-collision ability of the front part of the vehicle body 100 are significantly enhanced, and the structural layout of the vehicle body 100 can be optimized, and the safety performance of the vehicle body 100 can be improved.

[0085] At the same time, through the integrated design of the front panel 10, the number of parts is reduced and the sealing is ensured while ensuring the force transmission channel, which solves the problems of a large number of parts, complex structural processability, and poor water tightness of the passenger compartment, improves the ability of the structure to resist deformation, and facilitates reducing the weight of the vehicle and production costs.
