As part of the inventive concept, before describing the embodiments of the present utility model, the cause of the decrease in the impact resistance of the vehicle body in the related art needs to be analyzed, and the technical solution of the embodiments of the present utility model is obtained through reasonable analysis.
In the related art, a fuel vehicle employs a floor rail to transmit the vehicle body stress. However, in the new energy vehicle, the floor side member is omitted or the longitudinal dimension of the floor side member is reduced because of the battery. The front side member forward-backward direction 4b carries a load transmitted backward in the front side member forward-backward direction 4b through the floor side member and the front wall plate, which is thin in thickness in order to avoid interference with the battery. Therefore, the impact force transmitted from the vehicle body needs to be transmitted to the front panel through the front side member front-rear direction 4b, and then to be transmitted to each part of the vehicle body through the front panel into a plurality of force transmission paths. If the longitudinal dimension of the floor stringer is eliminated or reduced, so that the force transmitted to the front wall panel is increased, the front wall panel is damaged in the process of transmitting the force, or the front wall panel is deformed, and the battery is damaged.
