Description

A kind of Portable full automatic folding electric bicycle

Technical field

The present invention relates to a kind of electric bicycle more particularly to a kind of Portable full automatic folding electric bicycles.

Background technology

Currently, Chinese most cities resident still relies on public transportation system network to meet daily working and trip Demand, however as the quickening of Urbanization Process In China, city size is growing with area, and people's distance on and off duty is also more next It is remoter.Although increasingly perfect public transportation system greatly facilitates the trip of people, however, subway station, bus station and family Or the final stage distance between work unit but becomes the last bottleneck efficiently gone on a journey, this segment distance is on 1~5 kilometer of left side The right side is completed by walking substantially, and institute time-consuming few then 5 minutes, at most 20 to 30 minutes greatly reduce out line efficiency.

To solve the problems, such as " trip final stage distance ", various portable, folding the vehicles, including bicycle, electricity Motor-car etc. is developed, and meets this demand.Wherein, electric motor bicycle with folding is laborsaving with its, conveniently obtains more and more The favor of people, various method for folding, which are also developed, meets this demand (patent CN 102167115 A, CN 105083444 A,CN 103569276 A).However, there is also following disadvantages in currently existing scheme：

1) what is folded is less efficient, and people need to break one or more folding joints into two with one's hands manually, could complete to fold；

2) fold after vehicle volume it is still larger, it is inconvenient to carry, and the structures such as wheel mostly it is exposed outside, influence public affairs Other passengers on vehicle or subway are handed over therefore not also to be allowed to take bus and subway；It can not solve trip final stage The problem of distance；

3) carrying for folding rear vehicle relies on manpower or tows or carry on one's shoulders or with both hands substantially, it has not been convenient to which strength is smaller Ms uses；

4) entire folding system structure is more complicated, and design and maintenance cost are high.

4) electric vehicle does not have intelligence and social functions, and car owner can not grasp charging situation, can not record capable trip in time Track can not count market condition, can not optimize plan of travel.
