TORQUE SENSOR AND ELECTRIC BICYCLE USING SAME

摘要

A torque sensor for electrically assisting a vehicle with pedals includes a housing, a first gear, an actuator, and a control circuit. The housing defines a receiving chamber and is configured to be coupled to a drive member. The first gear is rotatably mounted in the receiving chamber. The actuator is received in the receiving chamber and is driven by the first gear. The control circuit including a resistor is received in the receiving chamber and the actuator slides along the resistor as a rider applies force to the pedals, thus for adjusting a resistance value of the control circuit, to allow the control circuit to output a signal 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, the housing configured to be coupled to a drive member; a first gear rotatably mounted in the receiving chamber; an actuator received in the receiving chamber and driven by the first gear; and a control circuit comprising a resistor, the resistor received in the receiving chamber and be in slidable contact with the actuator; wherein the actuator is made to slide by the first gear along the resistor for adjusting a resistance value of the control circuit, the first gear is capable of being rotated under an external force, thereby enabling the control circuit to generate a signal for controlling a torque output of the drive member.
