A crush structure is provided on the front crash box 2052 to absorb energy upon impact.

The distance from the offset bracket 2051 to the center line of the vehicle in the longitudinal direction gradually decreases in the front-to-rear direction. Thus, when the front anti-collision beam 205 is collided, the force transmission path is decomposed into the length direction along the vehicle and the width direction along the vehicle by the offset collision support 2051 and the offset collision block 1016 along the length direction of the vehicle, so that the force is prevented from being directly transmitted to the passenger cabin, the damage of the collision to drivers and passengers is reduced, and the collision performance is improved.

The second side sills 104 are provided in two and are arranged at intervals in the width direction of the vehicle, and the fuel tank is fixed to the second side sills 104 by a strap. The second small longitudinal beam 104 is correspondingly provided with corresponding strap perforations, and a plurality of strap perforations are arranged.

As shown in fig. 1 and 14, the frame further includes a sixth cross member 207, the sixth cross member 207 is disposed on a side of the fifth cross member 206 away from the third cross member 201, the sixth cross member 207 is connected to the first side member 101 and the second side member, and the second cross member 204 is provided with a rear suspension mounting bracket 601. The rear suspension mounting bracket 601 is used to mount the suspension of the rear motor. The rear suspension mounting bracket 601 is provided in plurality and is provided on the sixth cross member 207 at intervals in the width direction of the vehicle. The sixth beam 207 includes a sixth beam upper plate and a sixth beam lower plate that are snap-connected up and down. The sixth cross beam upper plate and the sixth cross beam lower plate are buckled and welded.

As shown in fig. 1 and 15, the frame further includes a rear impact beam 208, the rear impact beam 208 is connected to the rear sides of the first longitudinal beam 101 and the second longitudinal beam, and rear energy absorbing boxes 2081 are disposed at the rear ends of the rear impact beam 208, the first longitudinal beam 101 and the second longitudinal beam. The rear crash boxes 2081 are provided with crush structures to absorb energy upon impact.

The invention further provides a vehicle, which comprises the frame.

The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the invention.
