Electric bicycle drive assembly with torque sensing

Abstract

An electric bicycle driving assembly having a torsion sensing function is especially integrated to a frame of the bicycle, and the bicycle is provided with a fluted disc. The electric bicycle drivingassembly comprises a torsion detecting mechanism provided with a sensing portion and a torsion detecting assembly, an engaging and disengaging mechanism comprising a first bearing and a one-way ring body, and a sleeving part combined with the one-way ring body of the engaging and disengaging mechanism, wherein a pedal shaft rod mainly drives the torsion detecting mechanism to rotate, a signal canbe produced and transmitted to a controller module and a motor assembly is started when the torsion detecting mechanism detects a rotating torsion, then the motor assembly drives the sleeving part andthe engaging and disengaging mechanism to rotate, the engaging and disengaging mechanism drives the fluted disc of the bicycle to rotate, the bicycle can utilize the torsion produced through pedalingof a rider to start the controller module and then drive the motor assembly, and the drive of the motor assembly is used as input power of the bicycle and accordingly is a power assisting advantage when the environment demand of the user can be perfectly met.

Description

technical field [0001] The invention relates to a drive assembly, in particular to an electric bicycle drive assembly with torsion perception that can perfectly meet the riding needs of bicycles in various environments. Background technique [0002] As people increasingly advocate improving the quality of life and strengthening health, coupled with changes in lifestyle, people pay more and more attention to the quality of leisure life; therefore, more and more people choose to use bicycles that consume less energy as a means of transportation. As a means of transportation or as a main tool for leisure and sports; as far as bicycles are concerned, because they can simultaneously strengthen the body and protect the environment, riding a bicycle has become a new trend and a new trend of modern sports, leisure, and parent-child fun. fashion movement. [0003] However, although riding a bicycle can strengthen the body, for the older elders or younger children, if they ride a bic...

[0004] However, the existing electric bicycles can only control the start of the electric motor in a passive manner, that is, the existing electric bicycle mainly sets the controller for controlling the start of the electric motor at the handle of the bicycle, so that the electric motor of the existing electric bicycle can only be completely It can only be started by the user operating the controller; in this way, when the user does not know how to operate the controller, the electric motor cannot be started; or, when the user is riding an existing electric bicycle, in addition to In addition to paying attention to the road conditions ahead, you must also focus on the operation of the controller, which can easily cause the user to be distracted when riding an electric bicycle and cause danger

[0005] And, as China Taiwan Patent Announcement No. I142603 Invention Discloses a Clutch Type Bicycle Electric Driving Device and Its Clutch Driver and Announcement No. TW20135038 Invention Specification Discloses a Carrier Transmission System, It Mainly Sequences the Transmission Assembly As a result, its structure cannot be simplified and reduced, which will inevitably lead to too large span width between the left and right pedals of the bicycle, and it is impossible to obtain a better span practicality; in addition, Also resulting in too many transmission components and components, which relatively increases the cost of parts and assembly man-hours
