Problems solved by technology

However, the strain gauge needs to be arranged on the central axis, so that the data acquisition circuit of the sensor must also be fixedly arranged on the central axis, which increases the difficulty of power supply and data transmission of the data acquisition circuit.

Embodiment Construction

[0014] Preferred embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although preferred embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0015] At present, most electric bicycles support the assist mode. There are two technical solutions to realize the assist mode, one is a speed sensor, and the other is a torque sensor.

[0016] The speed sensor can collect the speed at which the user pedals, and control the motor output of the electric bicycle according to the pedal speed. The driving force output by the motor is proportional to the pedal speed, thereby achieving the purpos...

Abstract

The invention discloses a torque sensor module and an electric bicycle based on the torque sensor module. The torque sensor module uses a battery module of a replaceable battery to supply power, and converts the voltage signal into torque data by collecting a voltage signal output by a torque sensor composed of a strain gauge, and then sends the torque data to a wireless data receiving terminal through a wireless data transmitting terminal. As a result, a complex wired power supply circuit can be eliminated, and the implementation cost can be reduced. Moreover, through the non-contact torque data acquisition and transmission process, the data transmission speed is fast, the distance is long and the anti-interference ability is strong, which improves the implementation flexibility.

Description

technical field [0001] The invention relates to sensor technology, in particular to a torque sensor module and an electric bicycle based on the torque sensor module. Background technique [0002] At present, most electric bicycles support power-assisted mode to assist users in riding. In the prior art, the assist mode can be realized based on various sensors, such as a speed sensor, a center shaft torque sensor, a rear axle dropout sensor, and the like. [0003] The strain gauge detection solution is simple and easy to implement, low in cost and high in reliability, and has become the most cost-effective mid-axis torque sensor solution. However, the strain gauge needs to be arranged on the central axis, so that the data acquisition circuit of the sensor must also be fixedly arranged on the central axis, which increases the difficulty of power supply and data transmission of the data acquisition circuit. [0004] Therefore, there is a need for a sensor module that is simple...
