Torsion detecting rim motor

Abstract

The invention relates to a torsion measuring device, in particular to a torsion detecting rim motor, which comprises a fixed device, a movable device, a power motor and an elastic component, wherein the fixed device is arranged on a vehicle and is provided with a sensor; the movable device is sleeved on the fixed device and is connected with a wheel through a stock; a linked module for receiving an external force is arranged on one side of the stock, and a driven rotary gate disc of a plurality of first detected area is arranged on the other side of the stock; the linked module is provided with a driving rotary grate disc which are superposed with the driven rotary grate disc; a plurality of second detected areas are formed on the driving rotary grate disc; the power motor is sleeved on the fixed device and accommodated in the stock of the movable device for driving the movable device to rotate; and the two ends of the elastic component bears the forces applied by the stock of the movable device and the linked module. In the invention, the change between the detected areas can be detected, the power motor, according to data size, can be started to provide corresponding auxiliary power, and time difference is eliminated and the operation simplicity is improved.

Description

technical field [0001] The invention relates to a torque measuring device, in particular to a rim motor with torque detection. Background technique [0002] Electric bicycles are currently one of the most popular means of transportation, especially under the environmental trend that the concepts of environmental protection, energy saving and carbon reduction are generally deeply rooted in the hearts of the people, electric bicycles have gradually replaced bicycles and become the mainstream of light-duty means of transportation in the future; however , in the structure of the electric bicycle, the most important power source is the auxiliary transmission power source such as the electric motor, therefore, it is necessary to control the operation of this auxiliary transmission power source well, so that the electric bicycle can , to achieve the effect of man-vehicle integration, otherwise it will only increase the power consumption and increase the safety issues of personnel r...

AI Technical Summary

Problems solved by technology

[0008] 2. The first and second magnetic assemblies B21 and C1 are provided on the adjacent sides of the four pushing seats B2 and fixing seats C. When the bicycle is started, it is necessary to step on the pedal to rotate more than 1 / 4 circle. The magnetic sensor will detect the magnitude of the torque and start the motor. If it is necessary to start the motor after averaging multiple detected torque values, it is necessary to step on the pedal and rotate for more than 1 / 2 circle. When the auxiliary power of the motor is most needed, the lack of timely auxiliary force cannot be provided, and the distance between the first and second magnetic components B21 and C1 is large, resulting in the inability to accurately detect the torque

[0009] The above-mentioned commonly used torque detection device has many problems and deficiencies, which is the goal that the inventors and those engaged in this industry want to improve.
