Technical Field

The invention relates to the technical field of shared three-wheeled electric vehicles, in particular to a shared three-wheeled electric vehicle convenient to fold.

Background

Due to the limitation of high price, short driving mileage and other factors of the battery, many developed pure electric vehicle products cannot enter the market, and the sales volume of the products on the market is not optimistic and cannot be accepted by consumers. In the face of the existing high-end pure electric vehicle product without a form with good market prospect, industry experts build and develop a small-sized low-speed electric vehicle with high cost performance, so that the existing technology can be effectively utilized to develop energy-saving and environment-friendly vehicles.

Through on-site investigation of the models and flow rates of the vehicles in the city center, a huge product gap exists between the two-wheel battery car and the four-wheel small car. The field research on the number of taxi passengers shows that the number of taxi passengers is more than 80% by single and double people, and then the taxi passengers take three people, about 15% and the taxi passengers take four people rarely. This shows that if two shared three-wheeled electric vehicles are designed and incorporated into a public rental system, the current traffic situation of a large city can be greatly relieved, and a certain number of existing vehicles, especially private cars, can be replaced.

The three-wheeled electric vehicle is favorable for relieving the traveling problem. Compared with a two-wheeled battery car, the three-wheeled electric car has the following advantages: firstly, the safety and stability are high, the comfort is high, and the space is increased. Secondly, the sunshade is rain-proof, takes more comfortablely. Thirdly, the three wheels have strong grip and are not easy to fall over. Thirdly, the brake and the turning are more stable and not easy to sideslip. Even if the bicycle sideslips, the bicycle is not easy to fall due to the three wheels.

However, the conventional three-wheeled electric vehicle on the market at present is put on the market as a shared vehicle, and the following problems also exist: compared with a two-wheeled electric vehicle, the three-wheeled electric vehicle has wider wheelbase of two rear wheels, occupies larger floor area in a public area, occupies more public resources and is not beneficial to large-scale market release.
