Description

Technical Field

[0001] The utility model relates to the technical field of drive devices, in particular to a booster device, which is specifically applied in a wheel on a vehicle. Background Art

[0002] With the rapid development of social economy, people's requirements for energy conservation and environmental protection are becoming increasingly profound, and an environmentally friendly and low-carbon mode of travel is becoming more and more popular.

[0003] When riding a traditional human-powered bicycle or an electric or motorized two-wheeled vehicle, the user needs to expend considerable effort, electricity, or mechanical power to drive the vehicle forward, especially when riding uphill or carrying a heavy load.

[0004] At present, the transmission wheels are designed as an integrated whole, and usually they come to a stop naturally after the driving power (including human, electric and motor power) of the driving wheels and the friction force are balanced. There is no power assist device on the wheels, and they cannot assist the wheels by themselves, thereby reducing the travel distance and wasting manpower and power resources. Utility Model Content

[0005] The purpose of the utility model is to provide a booster device to assist wheels, thereby increasing the travel distance and reducing manpower and power, which is beneficial to environmental protection.

[0006] The above technical objectives of the present utility model are achieved through the following technical solutions: A booster device, used in the wheel of a vehicle, includes a central shaft, a fixed wheel, a rotating wheel, an inner annular permanent magnet and an outer annular permanent magnet, the outer wall of the central shaft is fixedly connected to the center of the fixed wheel, and first grooves are arranged at intervals of even multiples along the circular edge of the fixed wheel, the size and shape of the first grooves match those of the inner annular permanent magnet, the inner annular permanent magnet includes a first N-level body and a first S-level body, the first N-level body and the first S-level body are alternately fixedly connected to the first grooves, the rotating wheel is annular, the inner ring of the rotating wheel is fixedly assembled with the outer ring of the fixed wheel, and second grooves corresponding to the number of the first grooves are arranged at intervals along the inner ring of the rotating wheel, the size and shape of the second grooves match those of the outer annular permanent magnet, the outer annular permanent magnet includes a second N-level body and a second S-level body, the second N-level body and the second S-level body are alternately fixedly connected to the second grooves.

[0007] The effect of the above technical solution is: the magnetic torque generated by the outer annular permanent magnet and the inner annular permanent magnet will drive the rotating wheel to continue rotating forward, providing power for the wheel, making human riding more labor-saving or increasing the range of the electric vehicle more environmentally friendly.

[0008] The utility model is further configured to further include an end cover, which is fixedly connected to the side of the rotating wheel by bolts. A mounting hole is opened on the end cover, and the mounting hole is sleeved on the central shaft.

[0009] By adopting the above technical solution, the end cover can protect the outer annular permanent magnet and the inner annular permanent magnet.

[0010] The utility model is further configured such that a bearing is provided on the end cover, and the bearing is sleeved on the central shaft.

[0011] By adopting the above technical solution, the bearing can reduce the friction between the end cover and the vehicle, ensuring that the device can rotate smoothly and efficiently. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The present invention will be described in further detail below with reference to the accompanying drawings.

[0023] like Figure 1-8 As shown, a booster device is used in a wheel on a vehicle, comprising a central shaft 1, a fixed wheel 2, a rotating wheel 3, an inner annular permanent magnet 4 and an outer annular permanent magnet 5, wherein the central shaft 1 is fixedly connected to the center of the fixed wheel 2, and four first grooves 21 are provided at intervals along the circular edge of the fixed wheel 2, the size and shape of the first grooves 21 matching the size and shape of the inner annular permanent magnet 4, and the inner annular permanent magnet 4 comprises a first N-level body 41 and a first S-level body 42, and the first N-level body 41 and the first S-level body 42 are alternately fixedly connected to the first groove 21; the rotating wheel 3 is annular, and the inner ring of the rotating wheel 3 is aligned with the outer ring of the fixed wheel 2 Assembly, second grooves 31 corresponding to the number of the first grooves 21 are provided at intervals along the inner ring of the rotating wheel 3, the size and shape of the second grooves 31 match the outer annular permanent magnet 5, the outer annular permanent magnet 5 includes a second N-level body 51 and a second S-level body 52, the second N-level body 51 and the second S-level body 52 are alternately fixedly connected to each other on the second grooves 31, and also includes an end cover 6, the end cover 6 is fixedly connected to the side of the rotating wheel 3 by bolts 7, a mounting hole 8 is opened in the center of the end cover 6, the mounting hole 8 is sleeved on the central shaft 1, and a bearing 9 is provided on the end cover 6, and the bearing 9 is sleeved on the central shaft 1.

[0024] Working principle: When driving, the wheels will rotate. When reaching the parking position or during driving, the driving power is less than the friction force, and the inner annular permanent magnet and the outer annular permanent magnet in the wheel are in an unbalanced state, the magnetic force generated by the inner annular permanent magnet 4 and the outer annular permanent magnet 5 in the wheel will generate a rotational torque. Since the inner annular permanent magnet 4 is fixed on the fixed wheel 2 and cannot rotate, and the outer annular permanent magnet 5 is fixed on the rotating wheel 3, under the action of the magnetic torque, the outer annular permanent magnet 5 and the rotating wheel 3 rotate around the central axis 1 together, so that the bicycle wheel provides power, thereby increasing the range and reducing manpower and power, making human riding more labor-saving or increasing the range of electric vehicles, which is beneficial to environmental protection.
