Description

A dual-purpose electric and manpower vehicle

technical field

The utility model relates to the technical field of automobiles, in particular to an electric and manpower dual-purpose vehicle.

Background technique

With the development of society, people's living standards continue to improve, and people's mentality has undergone great changes. They no longer stick to their homes, but are eager to go out, or go outing, or visit friends. People are constantly pursuing a higher quality of life. Some families directly take the family car to travel, but for most families, the family car is a luxury. At the same time, if the travel distance is not far, it is completely unnecessary to take a family car, and the exhaust gas emitted by the family car will also have a great impact on the environment, so the family electric car came into being.

Existing household electric vehicle is generally divided into two kinds: a kind of is the bicycle of manpower and electric power dual-purpose or simple electric motorcycle, and another kind is electric tricycle. For electric bicycles and electric motorcycles, there are obviously two shortcomings. First, the car body is small, and the horsepower of the whole car is small, which can only meet the short-distance driving of a single person, and cannot load heavy objects; secondly, the rear of the car body can carry passengers. The space is small, the front wheels of the car are flexible in steering, and the car is prone to bumps during driving, making it uncomfortable for passengers to sit on. For the electric tricycle, because it is only driven by electricity, and because the car body is relatively large, it will cause a lot of trouble to move the car body after the power is exhausted during driving, and the three-wheel electric car also obviously has problems. The driving is not stable, and passengers feel uncomfortable sitting on it, which causes a lot of trouble for passengers who take family as a unit to travel outdoors, and affects the mood of travel.
