Description

Technical Field

[0001] The utility model relates to the technical field of front fork structures, and particularly relates to a front fork for an electric scooter. Background Technique

[0002] The front fork structure is a component that connects the front wheel and the vehicle body. Since it is divided into left and right arms to support the front wheel and looks like a fork, it is commonly called a front fork. The front fork component is located in the front part of the scooter. Its upper end is connected to the handlebar component, the frame component is matched with the front tube, and the lower end is matched with the front axle component to form the steering system of the scooter. The working sequence of the front fork should be: encountering an obstacle - the front fork is compressed - reaching the extreme point - being rebounded to the original length (the rebounding speed is affected by damping) - the bouncing system work ends. Based on the above, the inventor found the following problems: The current design of the scooter front fork is relatively simple, usually composed of two independent fork tubes, directly connected to the front wheel axle, which can reduce the weight of the front fork and improve the overall portability of the scooter. However, this structure cancels the fork bridge, making it inconvenient to install the mudguard and inconvenient to use.

[0003] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a front fork for an electric scooter is provided with the expectation of achieving a more practical value. Content of the Utility Model
