Description

Electric car frame

A frame, especially an electric vehicle frame that can freely adjust the frame to be elongated or shortened.

A battery electric vehicle is a vehicle that supplies power to an electric motor via a power storage unit mounted on the vehicle, and then converts the electric energy into kinetic energy by the electric motor to push the tire to move. As the world's crude oil prices continue to rise, the demand for electric vehicles is gradually increasing, and the structural basis of electric vehicles comes from its frame. The quality of the frame is directly related to the handling, performance and comfort of the car. .Wait. At present, the mainstream of the frame is an integrated frame that can be mass-produced for mechanized flow production. The advantage of the frame is that the production cost can be greatly reduced, and the impact protection and the rigidity of the vehicle body are good.

However, the current electric vehicle frame has the following problems in production:

(1) The integrated frame uses a large amount of metal, which is heavy and takes up space, and the structure cannot be adjusted arbitrarily.
