An electric vehicle wheel position conversion device and a land-air dual-purpose electric vehicle

Abstract

The invention discloses a wheel position changing device of an electric vehicle. The wheel position changing device comprises: an axle, a steering bracket, a motor base, a piston rod, a spring, a steering motor and a retractable hydraulic cylinder, wherein the axle penetrates through the center of a wheel hub motor and is fixed with a stator of the wheel hub motor; a wheel freely rotates relative to the axle; the steering bracket is fixedly connected with the axle or the steering bracket and the axle form a whole body; the steering bracket is provided with two parallel stretching-out legs; the motor base is arranged between the two stretching-out legs of the steering bracket and is provided with a containing space; the piston rod penetrates through the motor base and is fixed between the two stretching-out legs of the steering bracket; the spring is arranged between the motor base and the stretching-out legs of the steering bracket; the steering motor is arranged in the containing space and can drive the piston rod to rotate; the retractable hydraulic cylinder is arranged at the bottom of the vehicle and a piston rod of the retractable hydraulic cylinder is connected with the base and is used for enabling the integrated wheel to stretch out of a vehicle body. The invention further discloses a flying-driving electric vehicle.

Description

technical field [0001] The invention relates to the field of ground-air amphibious vehicles, in particular to an electric vehicle wheel position conversion device and a land-air dual-purpose electric vehicle. Background technique [0002] With the rapid development of modern social economy, cars are not only a means of transportation in daily life, but also a way of life for people. In recent years, the number of cars in cities has increased significantly, and traffic jams have become a daily phenomenon in most cities. Excessive traffic pressure will bring a series of problems and hidden dangers. How to effectively solve the traffic problems in modern cities has become urgent. [0003] Combined with the concept of flying cars proposed by Henry Ford, some people have proposed the idea of ​​relying on flying cars to relieve the pressure on ground traffic, which has also made flying cars a hot research topic in related industries around the world. It is not difficult to find ...

Problems solved by technology

The above two methods all have serious defects. Using a folded fixed-wing rotor or a ducted fan as a drive, the rotor and the duct will occupy a large amount of car body space, and the usable space in the car becomes very narrow, while using helicopters and cars Combined mode, the huge rotor on the roof will not allow the car to drive normally on the road, and the car needs to keep the surrounding area open when taking off
