Universal travelling electric vehicle

Abstract

The invention provides a universal travelling electric vehicle. The universal travelling electric vehicle comprises an operating system, a bottom frame, two steering driving wheels and three universal driven wheels, wherein the operating system is mounted on the bottom frame; the bottom frame comprises a front bracket, a rear bracket and two side brackets; two ends of the front bracket and the front ends of the two side brackets are fixedly connected integrally separately, and the two ends of the rear bracket and the rear ends of the two side brackets are fixedly connected integrally separately; the two steering driving wheels are mounted at the parts, close to the middle parts, of the corresponding side brackets separately; and the operating system comprises control switches, a motor, two manipulation handles and a base, wherein the control switches are used for controlling the starting and the stopping of the motor, the motor is used for driving the steering driving wheels to run, the two manipulation handles are used for controlling the running directions of the steering driving wheels, and the base is used for enabling a driver to lean and sit. According to the universal travelling electric vehicle disclosed by the invention, a worm wheel-worm transmission manner is adopted, so that the function of integrating driving and braking is realized, once the motor has a power failure, a worm stops rotating, connecting shafts are fixed by the worm, and braking is realized; and the appearance profile of the universal travelling electric vehicle is like a crab, and the electric vehicle also has the function of transverse travelling, so that the universal travelling electric vehicle is more appropriate and welcomed by users.

Description

technical field [0001] The invention belongs to the technical field of electric vehicles, in particular to a universal driving electric vehicle. Background technique [0002] For existing four-wheel and two-wheel electric vehicles on the market, there is a turning radius limit, which generally can only realize forward or backward travel, and travel in a relatively narrow space is greatly restricted. And the cars (such as self-balancing vehicles, Segways, etc.) that have realized turning in situ by two-wheel drive and two-wheel differential speed appearing on the market recently also have complex circuits and high costs. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the object of the present invention is to provide an electric vehicle with flexible operation and universal mobility. [0004] In order to achieve the above-mentioned purpose, the present invention has adopted following technical scheme: [0005] The invention pro...

Problems solved by technology

[0002] In view of the existing four-wheel and two-wheel electric vehicles on the market, there is a turning radius limit, and generally they can only drive forward or backward, and the driving in a relatively narrow space is greatly restricted.

However, the vehicles (such as self-balancing vehicles, Segways, etc.) that appear on the market through two-wheel drive and two-wheel differential speed to realize in-situ turning also have the problems of complex circuits and high cost.
