Problems solved by technology

In order to be easy to carry and reduce the storage space, the frame of the existing folding bicycle adopts one or more than two folding structures to realize the folding function, but the folding or unfolding is to be loosened or fastened by manual operation, which is laborious. Especially in summer, users generally wear open-toed shoes. It is extremely inconvenient to open the folded car with your feet. Excessive force will hurt your toes. The safety is not good. The force is too light, and it is not easy to open. , inconvenient

Abstract

The invention provides a semi-automatic folding moped, which can be automatically folded and spread, and is labor-saving, fast, convenient and safe in use. The semi-automatic folding moped comprises a frame, a front wheel, a back wheel, a saddle and an electric control system, wherein the frame comprises a front fork, a front vertical pipe, a handle, a back flat fork, a front connecting seat and a main bearing seat; the two ends of an upper connecting rod and the two ends of a lower connecting rod are rotatablely connected between the front connecting seat and the main bearing seat to form into a four-connecting rod structure; and the lower connecting rod is connected with the back flat fork though a pull rod. The semi-automatic folding moped is characterized in that an extension pipe structure supports a supporting pipe; the semi-automatic folding moped is further provided with a thrust mechanism of the supporting pipe; the electric control system comprises a three-phase DC brushless motor, a microcontroller and a first switch; when the frame is positioned in a folding status and needs to be opened, the first switch transmits a signal to the microcontroller to control the three-phase DC brushless motor to drive the back wheel to be backward turned till that the frame is spread; and when the frame is positioned in a spreading status and needs to be driven, a speed-adjusting handle controls the back wheel to be turned through the microcontroller to drive the moped to run.

Description

(1) Technical field [0001] The invention relates to the technical field of power-assisted bicycles, in particular to a semi-automatic folding power-assisted bicycle. (2) Background technology [0002] Existing folding bicycle, it comprises the vehicle frame with unfolding and folding function, assembly, front wheel, rear wheel, the saddle that is arranged on the vehicle frame and the electronic control system that drives front wheel or rear wheel. In order to be easy to carry and reduce the storage space, the frame of the existing folding bicycle adopts one or more than two folding structures to realize the folding function, but the folding or unfolding is to be loosened or fastened by manual operation, which is laborious. Especially in summer, users generally wear open-toed shoes. It is extremely inconvenient to open the folded car with your feet. Excessive force will hurt your toes. The safety is not good. The force is too light, and it is not easy to open. , It is also i...
