TORQUE SENSOR AND ELECTRIC BICYCLE USING SAME

摘要

A torque sensor for electrically assisting a vehicle with pedals includes a housing, a rotating member, an actuator, and an resistor. The housing defines a receiving chamber and is configured to be coupled to the driving member. The rotating member is rotatably mounted in the receiving chamber and configured to rotate under an external force. The resistor is received in the receiving chamber and the actuator slides along the electrical resistance and compresses a spring as a rider applies force to the pedals. The variable resistor is coupled to a controlling module which governs the assisting power. The disclosure also includes an electric bicycle using the torque sensor.

1. A torque sensor comprising:
a housing having a receiving chamber and configured to be coupled to a driving member; a rotating member rotatably mounted in the receiving chamber; an actuator received in the receiving chamber and coupled to the rotating member; a resistor received in the receiving chamber and be in slidable contact with the actuator the resistor configured to be electrically coupled to a controlling module; wherein the actuator is made to slide by the rotating member along the resistor for adjusting a resistance value of the controlling module, the rotating member is capable of being rotated under an external force, thereby enabling the controlling module to generate a signal for controlling a torque output of the driving member.
