Description

Technical Field

[0001] The utility model relates to the relevant field of active shock absorbers, in particular to a stepless adjustable electric-controlled active shock absorber. Background Art

[0002] Electronically controlled shock absorbers are a technology related to the automobile suspension system. They mainly achieve electronic control of the suspension system by manipulating the shock absorber solenoid valve. During the driving process of the car, the shock absorber will continuously absorb energy, thereby reducing the shock and vibration of the vehicle and improving the ride comfort. Through electronically controlled shock absorbers, car owners can adjust the hardness and softness of the shock absorber to adapt to different road conditions and driving styles.

[0003] In the prior art, electric shock absorbers have been widely used in most car brands, but the existing shock absorbers still have certain problems. For example, they do not have the ability to easily disassemble the nitrogen tank. The nitrogen tank and the shock absorber are welded and fixed, which is prone to sealing problems and is very troublesome to replace and maintain later, affecting the practicality and maintenance efficiency of the device. At the same time, the existing shock absorbers do not have the ability to clamp and store the power cord. The power cord naturally hangs on one side, which is more susceptible to external wear and pulling problems, affecting safety in use. Therefore, we need to upgrade and transform the existing technology to overcome its existing problems and shortcomings. Utility Model Content
