Description

Technical Field

[0001] The utility model relates to a scooter, in particular to an electric scooter with a double shock-absorbing structure. Background Art

[0002] As a means of transportation that combines walking, exercise and entertainment, scooters are very popular among people. Scooters generally include rollers, pedals, a pole connected to the pedals, and a handlebar installed on the top of the pole.

[0003] The patent with application number CN201911146478.4 discloses an electric scooter, in which the front end of the intersection of the rear wheel fixing fork is hinged by a rotating shaft, and a shock absorbing assembly is provided between the baffle and the intersection of the rear wheel fixing fork.

[0004] In order to improve the passability of the scooter in the above patents and prior art, the rear wheel is installed on a swing frame, and a shock absorber is arranged between the swing frame and the pedal for shock absorption. However, since the rear wheel needs to provide power, the swing frame and the single shock absorber structure have the problem of excessive swing amplitude, which causes the shock absorber to frequently and significantly extend and contract during each swing, resulting in a significant decrease in shock absorption capacity after a short period of practical use.
