The trolley comprises a frame, a handlebar, a rotating shaft, a bearing seat, a bearing, a front wheel, a pair of rear wheels, a seat and a support rod, the trolley also comprises a hub motor, a hub motor controller and a power supply, a cover piece is arranged on the upper end surface of the frame, the edge of thecover piece extends to the edge of the frame, the contour of the edge of the cover piece adapts to a frame edge contour, the upper portion of the rotating shaft is provided with a first folding hingewith a locking mechanism, the rotating shaft can be folded in the direction close to the cover piece around the first folding hinge, the lower end of the support rod is connected with the frame through a second folding hinge with a locking mechanism, the front wheel is rotationally connected with the lower end of the rotating shaft through a shock absorber, the hub motor is arranged in the front wheel and is electrically connected with the hub motor controller, the power supply is fixed on the frame below the cover piece and is electrically connected with the hub motor controller through a wire, a control button is further arranged on the wire connected between the power supply and the hub motor controller, and the scheme is reliable in implementation and flexible in use.

Description

technical field [0001] The invention belongs to the technical field of electric vehicles, in particular to a multifunctional portable single-person electric car. Background technique [0002] At present, with the improvement of people's living standards, people pay more attention to the enjoyment of life. When people travel and go sightseeing, they often ride a scooter, but sometimes they will get off the car to take pictures when they see beautiful scenery, or sometimes they are tired from riding. I would like to take a walk later, but at this time the car becomes a burden instead. In view of this, if it is possible to design a car that can be easily folded or can automatically follow, and when people don’t need it, it can realize the automatic follow function. Then the trouble will be greatly reduced. [0003] However, most of the existing folding bicycles are limited to non-electric small bicycles or one-time folding electric bicycles favored by some substitute drivers. ...

AI Technical Summary

Problems solved by technology

[0003] However, most of the existing folding bicycles are limited to non-electric small bicycles or one-time folding electric bicycles favored by some substitute drivers. Because most of them can only fold the handlebar part, even after folding, they need to take up a lot of space. Horizontal space or vertical space, so there are still some limitations

[0004] In addition, as far as the automatic following function is concerned, there are more and more domestic self-developed products for automatic following cars, but most of them have complex structures, low economical practicability, and unsatisfactory functions and performance.

There are a few cars on the market that use infrared positioning, but this kind of car only uses infrared positioning, and the error may be very large. Once there are many people nearby, it will be impossible to find the correct route to follow. Once it exceeds the positioning system The phenomenon of being unable to follow the distance will occur
