Single-side hub motor based on power generation tire

Abstract

The invention discloses a single-side hub motor based on a power generation tire. The motor comprises a wheel hub, a wheel hub motor arranged on one side of the wheel hub and a tire arranged on the outer side of the wheel hub. Permanent magnets are arranged on the inner side of the upper tire tread along the inner wall of the upper tire tread; the permanent magnets are arranged at intervals in thewidth direction of the inner side of the upper tire tread; a plurality of groups of copper coils are arranged on the outer side surface of the hub outer ring; gaps between the copper coils and the permanent magnets are correspondingly arranged; a motor rotor winding connected with the copper coils is arranged on the inner side surface of the hub outer ring; a motor stator permanent magnet corresponding to the motor rotor winding is arranged at the outer edge of the hub motor. According to the invention, through the arrangement of the permanent magnets and the copper coils, the tire deformation generated by vehicle weight is used for generating power, and the generated electric energy is directly converted into mechanical energy of the tire through the novel hub motor, thereby saving a storage link, and greatly reducing the electric energy loss. The electric energy generated by the power generation mode can also be stored in a storage battery to be used by a vehicle.

Description

technical field [0001] The invention relates to the technical field of in-wheel motors, in particular to a unilateral in-wheel motor based on power generation tires. Background technique [0002] In recent years, new energy vehicles have developed rapidly, and various models have emerged in an endless stream. Although national policies actively promote the development of new energy vehicles, the market performance of new energy vehicles is not good. The biggest obstacle restricting the development of new energy vehicles is the endurance problem caused by the current underdeveloped battery technology, as well as the long charging time of pure electric vehicles and the lack of charging piles, which also seriously affect consumers' car purchase choices. What's more deadly is that the battery's power storage capacity drops sharply in winter, and the cruising range is severely reduced, which makes new energy vehicles not accepted by consumers.

Although national policies actively promote the development of new energy vehicles, the market performance of new energy vehicles is not good

The biggest obstacle restricting the development of new energy vehicles is the endurance problem caused by the current underdeveloped battery technology, as well as the long charging time of pure electric vehicles and the lack of charging piles, which also seriously affect consumers' car purchase choices

What's more deadly is that the storage capacity of batteries drops sharply in winter, and the cruising range is seriously reduced, which makes new energy vehicles not accepted by consumers.

[0003] Although major car companies and scientific research institutions are actively researching battery technology, energy-saving technology, vehicle energy recovery technology, and charging technology, and the country is also stepping up the deployment of infrastructure such as charging piles, the results are minimal and the progress is slow. Effectively solve the main problems in the development of new energy vehicles. Therefore, a new type of vehicle energy recovery and energy saving device needs to be studied urgently
