Abstract

The invention relates to a novel power-assisted electric bicycle frame. A middle motor hanging rack is arranged at the lower end of a seat pipe, and the rear end of an inclined beam is fixedly weldedto the front part of the middle motor hanging rack; the middle part of the inclined beam is provided with a battery groove which does not transversely penetrate; a front fixing seat is arranged at thefront part of the bottom of the battery groove, a rear fixing seat is arranged at the rear part of the bottom of the battery groove; a head lock is installed on the front fixing seat, a tail base isinstalled on the rear fixing seat; a battery is installed in the battery groove, the tail part of the battery is connected with the tail base, the head part of the battery is connected with the head lock; the battery comprises an upper box body and a lower box body, an electric core and a circuit board are arranged between the upper box body and the lower box body, a charging terminal and a protective cover used for covering the charging terminal are arranged on the side surface of the tail part of the lower box body, and an exposed wiring terminal is also arranged on the tail part of the lower box body; fixed terminals are arranged at corresponding positions in the tail base. The novel power-assisted electric bicycle frame has the advantages of being simple in structure, capability of tightly combining the battery and the frame and effectively protecting the battery.

Description

technical field [0001] The invention belongs to the technical field of electric bicycles, in particular to a novel power-assisted electric bicycle frame. Background technique [0002] With the advancement of technology and the improvement of people's living standards, power-assisted electric bicycles have gradually entered people's daily lives and played an increasingly important role. Power-assisted electric bicycles have become an important choice for people's daily travel. The miniaturization and compact design of electric bicycles is the current development direction of power-assisted electric bicycles. Miniaturized electric bicycles are easy to store and move, and they are lighter to ride. They can be used as car companions to travel with the car, meeting the needs of short-distance riding. [0003] As an important part of the power-assisted electric bicycle, the frame has a decisive influence on the overall structural strength and riding effect of the bicycle. After y...
