Description

Technical Field

[0001] The utility model relates to the technical field of electric power-assisted bicycles, in particular to a frame connection structure for electric power-assisted bicycles. Background Art

[0002] Electric-assisted bicycles, also known as electric bicycles or electric-assisted bicycles, are vehicles that use batteries as an auxiliary energy source and incorporate motors, controllers, and control components. With the increasing use of electric bicycles in my country in recent years, consumers are increasingly favoring low-cost electric bicycles for short-distance travel, which are beneficial for the environment and alleviate urban traffic pressures.

[0003] Electric power-assisted bicycles require different shock-absorbing performance for different driving conditions. The shock-absorbing structure of existing electric power-assisted bicycles generally uses two connecting pieces to connect the front and rear parts of the frame, and a shock absorber is arranged between the two connecting pieces to achieve shock absorption of the electric power-assisted bicycle. Although the shock absorption effect of the electric power-assisted bicycle can be achieved during driving, the installation and fixation of the connecting pieces are overly dependent on manual experience due to the fact that the connecting pieces are arranged on both sides of the frame. They are affected by many human factors, which leads to reduced efficiency and accuracy in the installation and fixation of the connecting pieces. If the connecting pieces are installed asymmetrically, the shock absorber may damage the connecting pieces or even the shock absorber itself during operation.

[0004] Therefore, it is urgent to research and develop a frame connection structure for an electric power-assisted bicycle to solve the above technical problems. Summary of the Invention
