[0002] An electric scooter is a motor vehicle that is powered by a battery and then driven by an electric motor. In the suspension of an electric scooter, the upper part of the front fork is connected to the steering wheel, and the lower part is connected to the axle through a shock absorber to form the vehicle's guidance system. Whether the design of the shock absorber system and the steering system is reasonable is an important factor affecting the vehicle's driving comfort.

This patent uses the piston in the pendulum damper to swing back and forth in the damping chamber in the cylinder body to perform reciprocating damping rotation. Compared with the existing linear damper, the piston's range of motion is small and fixed, the overall damper volume is small, and the total volume of the damping chamber remains unchanged when the piston rotates. The piston is balanced and will not produce large pressure changes. Therefore, the problem of damping medium leakage is not prone to occur; the torsion spring can also provide elastic force to prevent the bracket from vibrating with the vibration equipment, further reducing the vibration of the vibration equipment. Compared with the existing single linear damper, the shock absorption effect is better.
