Abstract
The invention provides a chassis structure and a vehicle, and relates to the technical field of new energy. The chassis structure comprises a chassis body, the chassis body is provided with a containing cavity, the chassis body is provided with a bottom wall and a top wall which are opposite, an opening is formed in the bottom wall, and the opening communicates with the containing cavity; the bottom plate is arranged on the opening in a covering mode so as to seal the containing cavity; the battery cell pile is arranged in the accommodating cavity; the supporting piece is arranged between the bottom plate and the battery cell stack, extends in the battery cell thickness direction of the battery cell stack, and comprises a connecting part and a supporting part, the connecting part is detachably connected to the chassis main body, the supporting part abuts against the battery cell stack, and the supporting part is detachably connected to the bottom plate main body. And the battery cell stack is supported and fixed in the accommodating cavity. The battery core pile of the chassis structure provided by the invention can be mounted from one side of the bottom wall of the chassis, and the battery core pile is fixed through the supporting piece, so that the structural stability is relatively good.
