A semi-automatic opening and closing device for an electric folding bike

Abstract

A semiautomatic opening-closing device for electric folding bicycles is characterized in that a footboard is movably connected with a handlebar frame, a saddle support bar is movably connected with the footboard, the saddle support bar is provided with a locking bolt, a left wheel carrier and a right wheel carrier are movably connected to the rear end of the footboard, two magnets are disposed on fitting faces of the left and right wheel carriers, and an electromagnetic coil is disposed between the magnets which can attract each other. The semiautomatic opening-closing device has the advantages that the footboard and the handlebar frame are foldable, the wheel carriers and the footboard are foldable, the rear wheel carrier is turned to the bottom of the footboard after folded, two rear wheels are arranged on two sides of a front wheel, the folding process is highly automated, convenience is brought, labor is saved, the size of bicycles folded is greatly reduced, and less space is used.

Description

technical field [0001] The invention belongs to the field of folding bicycle accessories, and in particular relates to a semi-automatic opening and closing device of an electric folding bicycle. Background technique [0002] The electric folding car has the advantages of being foldable, easy to control, and easy to carry. During the folding process, no external tools are needed, and the car can be folded or unfolded manually. After folding, it can be stored and moved more conveniently, avoiding outdoor storage. unsafe hazards. [0003] At present, most electric folding bicycles are similar in appearance to bicycles or are converted from bicycles. The front and rear ends of the pedals are respectively equipped with front wheel frames and rear wheel frames. The front wheel frames are equipped with front wheels, and the rear wheel frames are equipped with rear wheels. There is a folding part in the middle of the frame, so that the frame can be folded horizontally in half with ...

AI Technical Summary

Problems solved by technology

[0004] However, the folding process of the existing vehicle frame is cumbersome, the folding and unfolding process is laborious, the degree of automation is low, and it is inconvenient to use; The rear length is reduced, but its width is widened, so the volume is not reduced, and because the front and rear wheel frames cannot be adjusted, there is a front and rear misalignment between the front and rear wheels
