Description

Technical Field

[0001] The present invention relates to the technical field of electric vehicle accessories, in particular to a shock-absorbing chassis of a new energy electric vehicle. Background Art

[0002] The shock-absorbing chassis of new energy electric vehicles refers to a specially designed shock-absorbing system added to the chassis structure of the electric vehicle to reduce the vibration and impact caused by bumps and uneven roads when the vehicle is driving. This chassis can improve driving comfort and stability, while also protecting the vehicle's suspension system and other important components. The use of a shock-absorbing chassis can effectively reduce the vibration and noise of the vehicle, improve riding comfort, and also help extend the service life of the vehicle.

[0003] In the prior art, a Chinese patent with publication number "CN204368272U" discloses a shock-absorbing chassis of an electric vehicle. By setting a shock-absorbing rod, when the wheel encounters bumps, under the action of the shock-absorbing rod and the swing arm, the wheel can move up and down, avoiding direct impact on the frame chassis, and realizing the first-level shock absorption of the vehicle body; by setting a guide column and a shock-absorbing spring, when vibration occurs during driving, the frame chassis moves up and down with a small displacement under the action of the shock-absorbing spring to avoid rigid impact, and realizing the second-level shock absorption of the vehicle body, so that the shock absorption effect of the electric vehicle chassis is better, and the problem of unreasonable design of the existing shock-absorbing device of electric vehicles is solved. The electric vehicle is in a bumpy road section, and the bumping phenomenon is very serious, which affects the operating performance of the electric vehicle. After the electric vehicle is subjected to vibration for a long time, the internal parts connection is easy to loosen and damage, and the service life of the electric vehicle is shortened.

[0004] In order to prevent the vibration force from directly acting on the car, the existing new energy electric vehicles usually install a shock absorbing mechanism on the chassis of the electric vehicle to absorb the vibration force acting on the car chassis through the shock absorbing mechanism. As in the distribution scheme described above, the first level of shock absorption is achieved by the shock absorbing rod and the swing arm, and the second level of shock absorption is achieved by the shock absorbing spring. However, in this scheme, the shock absorption method is too single, and it is impossible to perform a secondary reduction on the respective vibration forces during the first level of shock absorption and the second level of shock absorption. In this way, more vibration energy cannot be consumed, and the vibration energy that cannot be consumed will act on the car chassis, which will eventually affect the comfort of the vehicle during driving.
