an electric car

Abstract

The invention relates to an electric vehicle. The electric vehicle comprises a chassis mechanism and six wheel assemblies, wherein the chassis mechanism has a frame structure enclosed by two longitudinal connecting rod assemblies, a front connecting rod assembly and a back connecting rod assembly; the longitudinal connecting rod assemblies are fixed to corner vertical rods; the front connecting rod assembly and the back connecting rod assembly comprise first connecting rods and second connecting rods which are in hinged connection with each other; the other ends of the first connecting rods and the second connecting rods are hinged to the corner vertical rods; each wheel assembly is provided with an independent driving device; the wheel assemblies include four corner wheel assemblies arranged on the four corners of the frame structure; a middle wheel assembly is movably connected to the joint of each first connecting rod and each second connecting rod; a driving motor of each middle wheel assembly is used for controlling the middle wheel assembly to move forward or backward to change the distance between the two longitudinal connecting rod assemblies in order to change the width of the chassis mechanism. By adopting the electric vehicle, the middle wheel assemblies can be controlled to move forward or backward through the driving motors during advancing and parking, and the width of the chassis mechanism is changed.

Description

technical field [0001] The invention relates to a vehicle, in particular to a deformable electric vehicle. Background technique [0002] In recent years, the development of battery, motor, control and other technologies has promoted the development of electric vehicles. The high power density of the motor, the accuracy, speed and flexibility of the control have promoted the development of the decentralized power drive structure of electric vehicles, which in turn has promoted the development of electric vehicles in the direction of miniaturization, compactness and intelligence, so as to alleviate the increasing congestion. Urban traffic environment. At present, some electric vehicles have begun to try the design of deformable structures, such as the CityCar vehicle designed by the Massachusetts Institute of Technology in the United States, and the EO smart connected vehicle invented by the Germany Research Center, which can realize the front and rear folding of the electric...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned electric vehicle can save parking space by changing the length of the telescopic longitudinal beam to reduce the length of the chassis after parking, but since the chassis width of the above-mentioned electric vehicle cannot be changed, it cannot pass under narrow road conditions, and the chassis length cannot be changed during travel.
