Description

Technical Field

[0001] The utility model relates to the technical field of saddle pipe locks for electric vehicles, in particular to a saddle pipe lock structure for an electric bicycle. Background Art

[0002] An electric bicycle is a vehicle that uses a battery as an auxiliary energy source and is based on an ordinary bicycle. It is equipped with a motor, controller, battery, handlebars and other operating components and a display instrument system. The saddle and frame of an electric bicycle are removable, which makes it easy for people to adjust and can also be adapted to the person's body shape. A saddle clamp is usually used to fix the saddle.

[0003] However, current seat post locks are generally of the extrusion type, which uses the lock to bend at different angles to change the pressure on the seat post to achieve its positioning. This method has poor support stability. When subjected to force during a bumpy moment, the seat post may slide, causing the seat to shift, resulting in poor performance. In addition, the operation requires a large amount of force and is not convenient enough. Utility Model Content
