Semi-automatic folding moped

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 brushlessmotor, 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 assisted bicycles, in particular to a semi-automatic folding assisted bicycle. (2) Background technology [0002] The existing folding bicycle includes a frame with unfolding and folding functions, an assembly, a front wheel, a rear wheel, a saddle arranged on the frame, and an electronic control system for driving the front wheel or the rear wheel. In order to facilitate portability and reduce storage space, the frame of the existing folding bicycle adopts one or more folding structures to achieve the folding function, but the folding or unfolding is performed by manual operation to loosen or tighten, which is laborious. Especially in summer, users generally wear open-toed shoes. It is extremely inconvenient to use feet to open the folded car. Excessive force will damage the toes, and the safety is not good, the force is too light, and it is not easy to open, and it is laborious to use , Inconvenience. ...
