Abstract
The utility model discloses a motor for a built-in torque sensor of an electric bicycle, which comprises a moving sleeve, a shifting fork and a shaft. The shifting fork 4 is installed on the shaft 8 through a bearing, an inclined surface is arranged at the front end portion of the shifting fork 4, and the inclined surface of the shifting fork 4 is contacted with the inclined surface of the moving sleeve 1. A magnetic ring is arranged on the moving sleeve and rotates along the moving sleeve. The magnetic ring is corresponding to a linear Hall installed on the other end in the motor. The moving sleeve is further provided with a screw, and a spring is sleeved on the screw. The motor for the built-in torque sensor of the electric bicycle has the advantages of being simple in structure, convenient to operate, low in producing cost, high in reliability and the like.
Description
Technical field
The utility model relates to a kind of motor of electric bicycle, relates in particular to a kind of motor of built-in torque sensor.
Background technology
Use electric energy as the electric bicycle of actuating force because its moulding is light, can not cause tail gas pollution to be widely used.Common electric bicycle be full driven by power type mostly, and the driver can not regulate the output of motor at any time in going, when the driver needs power-assisted, as when sloping, suitable power-assisted not being provided in time upper and lower.
Summary of the invention
The utility model aims to provide the built-in torque sensor motor of a kind of electric bicycle, can regulate the power-assisted size at any time through driver's operation.
For realizing above-mentioned purpose, the utility model provides following technical scheme:
A kind of built-in torque sensor motor of electric bicycle; Comprise moving cover, shift fork and axle, on axle, shift fork contacts with moving cover shift fork through Bearing Installation; Said moving cover is provided with magnet ring; Magnet ring is corresponding to the linear Hall that is installed in the other end in the motor, and said moving putting also is provided with screw, and screw is with spring outward.
Said shift fork is provided with the inclined-plane in the side near moving cover, contacts with being arranged on the moving inclined-plane that puts, and can promote to move to overlap to prolong to move axially.
Said magnet ring adopts high-performance rare-earth permanent magnet material to process.
Because the utility model adopts can axially movable moving cover and back-moving spring, utilize simple structure to realize controlling at any time the purpose of power-assisted size, have characteristics such as easy to operate, inexpensive, convenient for maintaining.
Description of drawings
Accompanying drawing 1 be the utility model structural representation.
Embodiment
The embodiment that provides below in conjunction with accompanying drawing makes the utility model and further describing:
Magnet ring 2, shift fork 4, screw 5, spring 6, linear Hall 7 and axle 8 that the utility model comprises moving cover 1, makes with high-performance rare-earth permanent magnet material.On axle 8, the leading section of shift fork 4 is provided with the inclined-plane to shift fork 4 through Bearing Installation, and the inclined-plane of shift fork 4 contacts with the inclined-plane of moving cover 1.Magnet ring 2 is arranged on the moving cover 1.Magnet ring 2 is corresponding to the linear Hall that is installed in the motor other end 7.Also be provided with screw 5 on the moving cover 1, the screw 5 outer springs 6 that are with.Utilize spring 6 potential energy limit braking sleeve 1 and magnet rings 2 own to prolong axially moving to linear Hall 7 directions.
During use, the power that the driver applies passes to shift fork 4, shift fork 4 through with moving cover 1 between the inclined-plane contact the moving cover 1 of extruding, make moving overlap 1 vertically to linear Hall 7 near, magnet ring 2 also thereupon to linear Hall 7 near.Because the size of hall signal value depends on the distance of distance between magnet ring 2 and the linear Hall 7.When magnet ring 2 to linear Hall 7 near the time; The signal value that causes linear Hall 7 to produce increases; The controller of electric bicycle is carried the electric current of corresponding increase according to the increase of the hall signal value that receives to motor, and the power output of motor also changes thereupon, and therefore the power-assisted that the driver obtains increases.Simultaneously, because the effect of spring 6, the size of the power that the driver applies is directly proportional apart from distance with 7 of magnet ring 2 and linear Halls, and promptly the power that applies of driver is big more, and magnet ring 2 off-line property Halls 7 are near more, and the power-assisted that provides of motor is also just big more at this moment; The power that the driver applies is more little, and magnet ring 2 off-line property Halls 7 are far away more, and the power-assisted that this moment, motor provided is also just more little.When the cyclist no longer exerted oneself, spring 6 automatically reverted to initial position, and motor also just no longer provides power-assisted to the driver, thereby had realized that the driver can simply control the goal of the invention of power-assisted size.
