Rear frame part of foldable two-seated four-wheel electric motor car

Abstract

The invention relates to a rear frame part of a foldable two-seated four-wheel electric motor car, which comprises two rear wheels, a rear wheel carrier, a backrest frame and a seat frame lug, wherein the two rear wheels are installed on the lower end of the rear wheel carrier at intervals along the width direction, the backrest frame is arranged on the upper end of the rear wheel carrier, the seat frame lug is arranged on the rear wheel carrier, and a main shaft of each rear wheel is supported by two upright rods. The rear frame of the foldable four-wheel electric motor car has a simple structure, the rear wheels are scientifically stressed, the strength is high, the weight is light, the foldable function can be realized after the rear frame part is combined with a two-wheel front frame through a longitudinal connecting rack, the frame is made of an aluminum alloy pipe, so not only can the strength of the frame be guaranteed, but also overall weight of the car can be reduced, and the rear frame part is one of core parts of the foldable two-seated four-wheel electric motor car.

Description

Technical field [0001] The invention relates to a foldable four-wheel electric vehicle, in particular to a rear frame component of the foldable four-wheel electric vehicle. Background technique [0002] With the increase of the elderly population in society, the problem of social aging has become more and more prominent, and the travel problems of the elderly and the disabled have not been well resolved. Although we have developed electric tricycles or three-wheeled electric disabled vehicles for them, these models are the evolution of human tricycles. The front frame of this kind of electric tricycles is an old-fashioned hurdle type, and the hands and feet of the elderly and the disabled are not normal. Young people are so flexible and inconvenient to get on and off the car. At the same time, the stability of the tricycle is not good. If the steering radius is too small, the steering angle is too large, or the center of gravity is shifted, it is easy to roll over. An accident i...

Problems solved by technology

Although electric tricycles or three-wheeled electric disabled vehicles have been developed for them, these models are all evolved from human-powered tricycles. The front frame of this type of electric tricycle is an old-fashioned hurdle type, and the hands and feet of the elderly and disabled people are not normal. Young people are so flexible that it is very inconvenient to get on and off the car. At the same time, the stability of the tricycle is not good. If the steering radius is too small, the steering angle is too large, or the center of gravity of the seat is shifted during walking, it is easy to roll over, causing car rollover accident

Existing electric tricycles cannot be folded, occupy a large area and are not convenient for folding and storage, let alone put them in elevators to take them home for storage, and are not suitable for use by urban high-rise residential residents
