Description

Technical Field

[0001] The utility model relates to the technical field of shock absorbers, in particular to a front-wheel shock absorber for an electric bicycle which is convenient for assembly. Background Technique

[0002] The background technique of the front-wheel shock absorber of an electric bicycle relates to the problems of driving stability and riding comfort of the electric vehicle on uneven roads. The electric bicycle uses electric energy as the power source. Due to its advantages such as low energy consumption, low pollution, fast and convenient riding, it has gradually become the development trend of future transportation. When the electric bicycle travels on rough roads, the vibration of the vehicle body increases significantly, which will cause vibration and impact on the human body, making people feel uncomfortable. At the same time, the vibration of the vehicle body will make it difficult for people to control the vehicle, resulting in unstable driving, not only increasing the journey time, making users suffer from bumps, but even causing danger.

[0003] During the use of an electric bicycle, the front-wheel shock absorber plays a crucial role. It is responsible for absorbing the vibration and impact force transmitted from the road surface to ensure the stability and comfort of riding. Most of the existing front-wheel shock absorbers of electric bicycles have problems such as inconvenient assembly and difficult maintenance. Therefore, we propose a front-wheel shock absorber for an electric bicycle that is convenient for assembly to solve this problem. Content of the Utility Model

[0004] The purpose of the utility model is to provide a front-wheel shock absorber for an electric bicycle that is convenient for assembly to solve the problems raised in the above background technique.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

A thread groove matching the inner side of the threaded ring is formed on the outside of the second threaded block.

[0012] In the present utility model, for the electric bicycle front wheel shock absorber that is easy to assemble, by rotating the threaded ring, the threaded ring is disengaged from the second threaded block on the reinforcing steel frame. At the same time, the restriction and protection of the rotating circular plate are released. Then, by rotating the rotating circular plate, while the rotating circular plate rotates, it drives the sliding round rod slidably installed thereon to move. The sliding round rod drives the limiting buckle fixedly installed at its bottom end to move, so that the limiting buckle is retracted into the limiting round rod, and once the limiting buckle is disengaged from the reinforcing steel frame. Then, the installation round block drives the first threaded block and multiple limiting round rods to move, so that they are disengaged from the reinforcing steel frame, and the disassembly is completed;
