Special rotating-joint linked folding electric bicycle

Abstract

The invention discloses a folding electric bicycle which comprises handles, a seat handle, a main girder, a rear suspension, batteries and wheels; and folding electric bicycle is characterized in that the bicycle is also provided with a brushless built-in planetary gear hub motor, a guide-rail oriented joint bearing, a tri-hinge stabilizing mechanism and a self-locked folding mechanism. Because of having unique stability, a motion side-turning preventing design implemented through the inclined-angle ground-griping of rear wheels, a special and clever shock absorption design and a superior driving control performance, the folding electric bicycle disclosed by the invention has a polar environment adaptability and a heavy-gradient conquering capacity. The folding electric bicycle disclosed by the invention is easy to fold and carry, therefore, the bicycle adapts to extensive consumer groups, and can relieve urban spaces and traffic pressures; and because the folding electric bicycle is burglarproof, people do not worry about the trips.

Description

technical field [0001] The present invention relates to a portable vehicle, more specifically, the present invention relates to a foldable electric vehicle which is convenient to fold. Background technique [0002] Folding bikes have been widely recognized by users in terms of portability because they are foldable and easy to carry. However, the folding bikes on the market still have the following problems: [0003] First: The structure of the folding bike is complicated when it is folded, and there are too many mechanisms and auxiliary actions for folding and opening. It takes time and effort to realize folding, opening and closing, and it is difficult to be accepted and promoted in the market. [0004] Second: In order to realize the lightness after folding, the designers always simplify the strength of materials, the size of the wheel half, and the transmission mechanism, so that the necessary reliability and labor-saving advantages of the folding bike cannot be achieve...

Problems solved by technology

[0003] First: The structure of the folding car is complicated when it is folded, and there are too many mechanisms and auxiliary actions for folding and opening

It takes time and effort to realize folding, opening and closing, and it is difficult to be accepted and promoted in the market

[0004] Second: In order to realize the lightness of folding bikes, the designers always simplify the material strength, wheel half size, and speed change mechanism, so that the necessary reliability and labor-saving advantages in real use cannot be achieved, which is rejected by consumers.

[0005] Third: At present, the folding mechanisms of folding bikes on the market are i
