Description

technical field [0001] The invention relates to a wheel and an electric vehicle, in particular to an integrated integrated wheel and an electric vehicle using the integrated wheel. Background technique [0002] The history of electric vehicles predates the cars powered by the internal combustion engine that we most commonly see today. The father of the DC motor, the Hungarian inventor and engineer Anyus Jedlik, first tested the electromagnetic rotating action device in the laboratory in 1828. American Thomas Davenport produced the first electric car driven by a DC motor in 1834. Between 1832 and 1838, Scotsman Robert Anderson invented the electric carriage, a vehicle powered by primary batteries that could not be recharged. [0003] An electric vehicle is a vehicle that uses a battery as an energy source, and converts electrical energy into mechanical energy through controllers, motors and other components to control the current and change the speed. Electric bicycle is a...

Problems solved by technology

[0004] With the rapid development of China's electric vehicle manufacturing industry, electric vehicles have become an indispensable means of transportation in countless families; however, ordinary electric bicycles still follow the traditional assembly route, with motors, batteries, and control panels installed on different parts of the body. Parts, electric vehicles with this structure have a complex body structure, large size, and heavy weight, which is not simple and beautiful from the perspective of installation and appearance. If the motor, battery, and control board can be integrated to form an integrated wheel, then It not only simplifies the installation process, but also beautifies the entire electric vehicle, making the structure of the electric vehicle simpler and lighter, such as the electric bicycle wheel set described in the application number 201510062207.6, which discloses the concept of the above-mentioned integrated wheel, but the structure disclosed Only briefly introduces the positional relationship of the components, but does not mention the wiring between the components. Due to the small installation space, the wiring and wiring between the components are also difficult, and the heat dissipation efficiency is relatively low. The kinetic energy transmission efficiency of the motor is not high; furthermore, the above application does not consider the battery charging problem. Once the battery storage power is exhausted, it cannot be charged, and because the battery is integrated on the wheel, the rotation of the wheel will have a certain impact on the wiring, so how to It will also become a big problem to realize the wiring between the battery and the charging interface

[0005] At the same time, existing electric vehicles often only have one battery to provide power, and their battery life is relatively weak. To increase the battery life, it is often necessary to add additional batteries or make technical improvements to the battery. Ordinary batteries often take up space and are heavy. Increasing the size and weight of electric vehicles does not meet the current requirements of "light weight and compactness" for electric vehicles; while improved batteries are expensive and require high technology, which increases the production cost of enterprises
