Description

Electric vehicle front shock absorber with inner and outer double springs

Technical Field

The utility model relates to the technical field of electric vehicle shock absorbers, in particular to an electric vehicle front shock absorber with inner and outer double springs.

Background Art

Shock absorbers are used to suppress the vibration caused by the rebound of the spring after absorbing shock and the impact from the road surface. They play an important role in the production of electric vehicles. They accelerate the attenuation of the vibration of the frame and body to improve the driving smoothness of the electric vehicle. When passing through uneven roads, although the shock-absorbing spring can filter the vibration of the road, the spring itself will still have reciprocating motion, and the shock absorber is used to suppress this spring jump.

After searching, the existing Chinese patent announcement number is: CN218817789U, which provides an inner and outer double spring air pressure front shock absorber. This patent uses an adjustment structure. When the rider is riding, the servo motor is started according to the rider's own weight, so that the rotating rod drives the gear to rotate. Since the outer surface of the gear and the rack plate are meshed with each other, the rack plate will move up and down in the inner cavity of the cylinder. If the rack plate moves upward, the air inside the cylinder increases, the damping force is small, and the body rebound amplitude is large, which is suitable for people with larger bodies. If the rack plate moves downward, the air inside the cylinder decreases, the damping force is large, and the body rebound amplitude is small, which is suitable for people with smaller bodies. Therefore, the purpose of adjusting the damping force according to the weight of the rider is achieved.

Although the above patent can adjust the damping force according to the weight of the rider, the above-mentioned internal and external double spring air pressure front shock absorber still has the following problems: it is inconvenient to disassemble and replace, and is not very practical.

In view of the above problems, a front shock absorber for an electric vehicle with inner and outer double springs is proposed.
