Problems solved by technology

[0003] One of the electric mopeds in the prior art senses the speed of the electric moped to determine when the electric motor needs to be activated to assist in driving forward, and several stages are preset on the electric moped in the prior art The option of motor output size is available; however, the controller on this electric scooter does not make judgments based on the load of the scooter or the weight of the rider, so it is always miscalculated auxiliary power

Abstract

The invention relates to a torsion sensing device of a scooter. The torsion sensing device comprises a torsion sensor, a one-way bearing, a fluted disc, two cranks and two pedals. The torsion sensor is provided with an outer tube, a middle tube and a force application shaft which are arranged in penetrating mode in the axial direction. An elastic part is connected between the middle tube and the force application shaft, the middle tube and the force application shaft are respectively provided with a first sensing disc and a second sensing disc, and a detection unit can detect changing of the relative angle of the first sensing disc and the second sensing disc to calculate pedaling force of a rider and further to control an electric motor to assist the scooter to advance to reduce load of the rider. The torsion sensing device has a simple structure and fast, sensitive and accurate sensing capability, can be assembled on various electric bicycles for use through simple processing, and can easily achieve the purpose of converting the electric bicycles to moped bicycles.

Description

Technical field [0001] The present invention relates to a torque sensing device for a moped, which can sense the amount of change in the torque applied by the rider to the vehicle, and accordingly control an electric motor to provide auxiliary power to overcome the terrain or the conditions of the vehicle when the vehicle is moving forward The torque sensing device of the moped that changes and increases the resistance. Background technique [0002] In addition to using human pedaling as the driving force for forward movement, the bicycle is also equipped with an electric motor to assist the driver. When the rider is climbing or tired, the electric motor can be used to assist in driving the bicycle forward to reduce riding. The burden of the occupant, this kind of bicycle that uses an electric motor to assist in driving at an appropriate time is generally called an "electric moped. In order to ensure the safety of electric scooters during riding, the general state has strict reg...
