Abstract

The invention discloses an electric automobile chassis which comprises a driving system, a travelling system, a steering system, a braking system, power batteries and an automobile frame, wherein the power batteries are embedded inside the automobile frame; the automobile frame is provided with a front cross beam and a rear cross beam; the power batteries are closed to the rear cross beam of the automobile frame; the automobile frame is correspondingly arranged below an automobile body; the driving system, the travelling system, the steering system and the braking system are correspondingly arranged on the automobile frame. The power batteries are embedded in the automobile frame, so that the weight and load of the automobile body are reduced; on the aspect of safe collision, the power batteries are protected by the automobile frame, the power batteries are prevented from being directly collided, and sufficient safe buffering space is reserved among the power batteries, so that the safety performance is improved; the gravity center of the whole automobile is lowered down, so that the control stability performance is also improved.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to an electric vehicle chassis. Background technique [0002] As a representative of new energy vehicles, electric vehicles have the advantages of economy and cleanliness. However, the driving range, collision safety and handling stability of electric vehicles have become the key factors restricting their development. [0003] An electric vehicle includes a body and a chassis corresponding to the body. The chassis generally includes a transmission system, a driving system, a steering system and a braking system. In the prior art, a power battery is fixedly installed on the body. For mileage, the measure of increasing the number of batteries is generally adopted, which increases the load on the body, thereby increasing the weight of the vehicle, which in turn will increase the requirements for the strength and stiffness of the vehicle accordingly. [0004] In the process of realizin...
