Description

Technical Field

[0001] The utility model relates to a scooter, in particular to an electric scooter with air bag shock absorption. Background Art

[0002] A scooter is a means of transportation. Currently, scooters are generally driven by holding the handles with both hands to control the direction, standing on the scooter pedals, and the scooter is driven by a motor to slide forward.

[0003] At present, the front wheel of the electric scooter is usually shock-absorbing by a shock-absorbing spring arranged on a rotating frame, and the rear wheel is usually installed on a swing frame, and then an inclined shock absorber is arranged at the tail end of the swing frame and the pedal assembly. When the rear wheel encounters an uneven road surface, the swing frame swings and cooperates with the shock absorber to achieve shock absorption.

[0004] In the above structure, the shock absorption at the front wheel is provided by a spring, and the hardness of the shock absorption cannot be quickly adjusted for different road surfaces. In addition, the elasticity of the spring changes after being used for a period of time, and the initial shock absorption effect cannot be achieved. The rear wheel adopts a swing frame and a shock absorber structure for shock absorption. Since the swing of the swing frame causes the angle to change, the elastic angle of the shock absorption changes after the angle change, which causes the component of force in the vertical direction to change, and the effect of the shock absorber is greatly reduced. Utility Model Content

[0005] Based on the fact that the hardness of the front wheel shock absorption cannot be adjusted in the prior art, and that the vertical force of the rear wheel through the structure of the swing frame and the shock absorber is small, and the shock absorber effect is weakened, the utility model provides an electric scooter with airbag shock absorption.
