Problems solved by technology
[0003] Hot-rolled bending of steel plates requires high cost of mold opening, and in practical applications, battery box brackets are often deformed or stress concentration leads to failure
Tailor-welded brackets are often de-soldered due to welding defects and fail
This kind of bracket is not only not conducive to the lightweight design of the vehicle, but also easily causes torsional deformation of the longitudinal beam of the vehicle body.

The invention discloses an electric bicycle and a battery box fixing assembly for the electric bicycle, wherein the battery box fixing assembly for the electric bicycle comprises at least two cross beams; at least two vertical beams separated along the length direction of the cross beam are arranged on each cross beam; one end of each vertical beam is connected with the corresponding cross beam and defines an installing space used for installing battery boxes. The battery box fixing assembly for the electric bicycle according to the invention has the advantages that through using the at least two separated vertical beams, the installing space used for installing the battery boxes is constructed on the cross beam, so that the vertical beams and the battery boxes can be arranged according to the number of the battery boxes and the model of the electric bicycle, the battery box fixing assembly is applicable to different electric bicycles, the weight of the battery boxes can be reasonably distributed, and the stability of the electric bicycle is improved.
Description
technical field [0001] The invention relates to the technical field of automobiles, in particular to an electric vehicle and a battery box fixing assembly for the electric vehicle. Background technique [0002] In the field of electric vehicles, especially pure electric vehicles, more power is needed to obtain a greater driving range. Due to the low energy density of batteries at this stage, the mass of the battery box is relatively large. The battery box of a pure electric truck is generally a cuboid or slightly rounded at the corners. The design of the cuboid battery box and the battery box fixing bracket is not well matched, and it is prone to deformation or welding failure. In the related technology, the shape of the battery box fixing bracket is divided into two types, one is "L" shape formed by hot rolling and bending of steel plate or "L" shape formed by tailor welding, and the other type adopts pallet structure. Completely wrap from the bottom of the battery box to ...
