Bicycle frame of electric bicycle

Abstract

The invention relates to a bicycle frame of an electric bicycle. The bicycle frame comprises a main bicycle frame beam, a handlebar connecting frame, a bicycle seat frame, a rear bicycle frame and a connecting and fixing rod, wherein the main bicycle frame beam is a curved beam and consists of a main beam upper segment, a main beam bent part and a main beam lower segment which are integrally formed. The middle part of the handlebar connecting frame is fixedly connected with the top part of the main beam upper segment. The bicycle seat frame is fixedly connected with the inside surface of the tail end of the main beam lower segment, The rear bicycle frame, the bicycle seat frame and the connecting and fixing rod form a triangle, and an inwardly-dished punching groove is formed in the inner side of the main beam bent part. A reinforcement support sheet is arranged on the outer side of the main beam bent part. A battery bearing plate is arranged on the surface of the inner side of the middle part of the main beam lower segment. The bicycle frame has the beneficial effects that the bicycle frame is simple in structure, and is convenient to use; and the firmness and the safety of the main beam of the electric bicycle can be effectively enhanced, so that a condition that the whole electric bicycle is scrapped since the main beam gets deformed due to external force impact is avoided . At the same time, the safety of a rider can be guaranteed.

Description

(1) Technical field [0001] The invention relates to a frame, in particular to an electric bicycle frame. (2) Background technology [0002] At present, electric bicycles are increasingly used by more and more people, and they have gradually become the mainstream means of transportation for people to travel. Most of the main beams of the electric bicycles on the market are made of one-time formed steel pipes. When the external force is impacted, it is easy to bend and deform, causing the main beam to be scrapped, thereby scrapping the entire electric vehicle, bringing great economic losses to the owner, and also posing a threat to the safety of the driver. At present, an electric bicycle frame that can effectively enhance the strength and safety of the electric bicycle frame has not been found and needs to be developed. (3) Contents of the invention [0003] In order to overcome the shortcomings of the existing frame, the present invention provides an electric bicycle fram...
