Semi-automatic and foldable moped

Abstract

A semi-automatic and foldable moped comprises a frame, a front wheel, a rear wheel and an electric control system. The frame comprises a front fork, a front vertical pipe, a handlebar and a rear flatfork, wherein the front fork is rotatably connected with a front connecting seat, the rear flat fork is rotatably connected with a main bearing seat, two ends of an upper connecting rod and two ends of a lower connecting rod are in rotatable connection with the front connecting seat and the main bearing seat to form a four-connecting-rod assembly. The front fork comprises a sliding part I and a sliding part II, wherein one end of the sliding part I is sleeved with the sliding part II and is provide with a component force part I, the other end of the sliding part I is in rotatable connection with the front connecting seat, the sliding part II is connected with the front wheel, a component force part II is arranged at the bottom of an inner cavity and is in a shape of a cavity, and a piezoelectric material block is arranged between the component force part I and the component force part II. The semi-automatic and foldable moped also comprises a lithium battery block, an upper connectingrod is hollow-out, the lithium battery block is arranged in the cavity of the upper connecting rod and is connected with the piezoelectric material block, and the lithium battery block is also electrically connected with a microcontroller and the like. The semi-automatic and foldable moped also comprises a spring II, wherein the spring II is connected with the component force part I and the component force part II, and the piezoelectric material block is arranged in the spring II.

Description

technical field [0001] The invention relates to the technical field of power-assisted bicycles, in particular to a semi-automatic folding power-assisted bicycle. Background technique [0002] The manufacture and use of bicycles has a history of hundreds of years. Bicycles have the characteristics of lightness, health, and green travel. However, with the acceleration of people's life rhythm, human-powered bicycles can no longer meet people's living and working requirements. In major cities, electric The use of car seems more general, but electric car is subjected to the influence of its power equipment, and volume is bigger, and carrying inconvenience. [0003] Generally speaking, electric vehicles commonly used in cities, regardless of brand or quality, have a disadvantage that they still occupy a certain space when not in use. Lightweight and portable e-bikes are gaining importance as they can provide a form of personal transportation to fill rising demand not met by publi...

Problems solved by technology

[0009] The applicant has been researching and developing this design for many years and combined with years of user feedback. For users, semi-automatic folding mopeds can indeed choose the normal vehicle state or the folded state in different occasions. At the same time, fast folding and motor reversal are also true for users. It is very convenient, and can even achieve the effect of one-button folding, but years of user experience and feedback from traffic accidents and user falls have also led to a big disadvantage of folding mopeds, which are unstable and too thin The body, multiple rotating joints and multiple shock-absorbing designs lead to the fact that the driver dare not drive more than 30 yards when in use, or step on the pedal when the speed is slightly faster, otherwise the body shakes severely, the body floats and encounters When going downhill, the body will be extremely unstable. If you use this kind of semi-automatic folding car to go shopping, you can’t carry the items at all, because the weight of the body itself is relatively light. If there are loads on other places other than the seat cushion, the center of gravity of the body will change when driving This is a problem that is always difficult to overcome for semi-automatic folding mopeds. At the same time, because the semi-automatic folding mopeds of the prior art only use a battery pack, the vehicle must be kept on the frame to control the folding of the vehicle through the hub motor. and keep it powered on, otherwise it will be laborious and time-consuming to fold manually
