Abstract

The invention discloses a bottom fork and motor connection structure of an electric bicycle. The bottom fork and motor connection structure comprises a bottom fork and a motor. The bottom fork is shaped like a Chinese character 'kai' structurally, and comprises a first branch arm and a second branch arm. The tail end of the first branch arm is fixed in a groove, formed by a motor shell, in one side of the motor through an anti-pulling piece and a compression screw. A motor wire outlet lug adhered to the first branch arm is processed on the left side of the first branch arm of the bottom fork and positioned on the outer side of the motor. The second branch arm is connected to a bottom fork bearing block through a bottom fork connection screw. The bottom fork bearing block sleeves one end of an output shaft of the motor through a bearing and is in rotatable connection with the output shaft. An inner ring of the bearing is fastened by a shaft-end nut. The bottom fork and motor connection structure of the electric bicycle has the advantages of high connection strength and assembly flexibility, low production cost, convenience in mounting and the like.

Description

technical field [0001] The invention relates to a connection structure, in particular to a connection structure between a flat fork and a motor of an electric bicycle. Background technique [0002] For the motor installed on a conventional electric bicycle, the motor shaft does not rotate, and the motor casing drives the wheel hub to rotate, and the flat fork is supported on the shaft protruding from both ends of the motor. And for the specially designed electric bicycle, the motor housing does not rotate, and the output shaft of the motor rotates to drive the hub to work. If this design adopts the motor installation method of a conventional electric bicycle, it cannot be installed. Contents of the invention [0003] The problem to be solved by the present invention is to overcome the deficiencies in the background technology and provide a connection structure between the electric bicycle fork and the motor. This connection structure has high connection strength, convenien...
