Abstract
The utility model relates to an electric bicycle with a chain pressure spring-type torque power sensor, which comprises a bicycle central axis chain drive system and a five way union installed on the bicycle frame, and is characterized in that the five way union is fixedly connected with a connecting plate; the connecting plate is hinged with a connecting rocker; the front end of the connecting rocker is hinged with the torque sensor fixed on the bicycle frame; and the rear end of the connecting rocker is hinged with a guide wheel meshed with the chain. The electric bicycle with the chain pressure spring-type torque power sensor has the benefits of having simple structure, low manufacturing cost, reliable performance and light weight; and through the adjustment on the length of the connecting rocker or the pressure of the pressure spring, the assisting effect of torque 1:1 or 1:2 is realized. The electric bicycle with the chain pressure spring-type torque power sensor can save the battery power and prolong the riding distance.
Description
Technical field
The utility model belongs to Electrical Bicycle, relates in particular to a kind of Electrical Bicycle that has chain compressed spring type moment-assistant sensor.
Background technology
Electrical Bicycle all is made up of body part, battery, drive disk assembly, microcomputer controller and the dynamometry sensing element (being commonly called as torque sensor) that tests the speed.Groundwork: be the parts that machinery, electronics, software and magnetics are organically combined, system adopts double magnetic circuit (initiatively magnetic circuit and passive magnetic circuit) Hall elastic angle difference counting, detect the dynamic force moment that produces when people's pin is stepped on, change dynamic torque signals into digital signal, transfer analog signal again to and export to controller, system finishes the memory function of setting and the coupling of processing with assurance and car load that make zero of systematic error by storing micro controller system.When riding, people's foot-operated power is measured by sensing element, handles through micro computer, and motor is exported corresponding power, makes riding of people very laborsaving.People's foot-operated power is big more, and the power of motor output is that electric power-assisted is also big more, as the same on the contrary.Torque sensor is the device for measuring force in the Electrical Bicycle, and its effect is a foot-operated power of measuring the people.Therefore its installation site must interrelate with people's foot-operated power.The installation site of torque sensor: A, pedal: foot pedal type torque sensor.Setting pressure sensor on pedal, manpower is applied on the pedal, and pressure sensor is the exportable voltage signal that changes with the manpower size, passes to microcomputer controller by a cover carbon brush mechanism, realizes manpower, electric power-assisted ratio output.Shortcoming: transmission route is long, and unreliable factor is many, should not adopt.B, crank: crank-type torque sensor.Strain-gauge is installed on crank, and when manpower scrunched, crank produced little distortion, strain-gauge output correspondent voltage signal.The size of output signal changes with the manpower size.Output signal is passed to microcomputer controller, realize manpower, electric power-assisted ratio output.C, chain sprocket: chain wheel type moment sensor.Chain sprocket is designed to driving and driven double-stranded wheel.Driving wheel and crank are fixed together, and flower wheel drives chain.Connect with spring between the driven wheel.When manpower scrunched, driving wheel drove the flower wheel motion by spring.At this moment will produce angular transposition between master and slave the wheel.Measure this angular transposition, by microcomputer controller processing angle displacement signal, and then realize between manpower, the electric power-assisted ratio output.D, axis: middle shaft type torque sensor: lay torque sensor at axis.When riding, axis is pedaled at pin, axis, under the effect of crank, rotate in bottom bracket axle.Simultaneously, the axis torque sensor is subjected to a downward power, and this power will act on the excentric sleeve.Excentric sleeve is installed in the five-way pipe.Because axis and bottom bracket axle and excentric sleeve decentraction, under the effect of this power, excentric sleeve will rotate in the five-way pipe, forms angular transposition.When manpower stopped to scrunch, under the effect of another one elastic element, excentric sleeve resetted.The size of the angular transposition of excentric sleeve changes with people's the power that scrunches size.Measure this and do not stop the angular transposition that changes, and be transferred to microcomputer controller, can realize that intelligence rides with voltage signal.Shortcoming: excentric sleeve processing more complicated has the certain precision requirement; There are six bearings that vary in size to make its cost higher in addition; Because the rotation of excentric sleeve drives chain sprocket and produces the front and back microdisplacement, this displacement meeting causes that chain produces degree of tightness and changes.
The utility model content
The utility model is in order to overcome deficiency of the prior art, a kind of Electrical Bicycle that has chain compressed spring type moment-assistant sensor to be provided, simple in structure, low cost, dependable performance, in light weight; By connect than length regulate or the adjusting of stage clip pressure assistant's effect of realize moment 1: 1 or 1: 2.
The utility model for achieving the above object, be achieved through the following technical solutions, a kind of Electrical Bicycle that has chain compressed spring type moment-assistant sensor, comprise the axis chain gear system of bicycle and be installed in five-way on the vehicle frame, it is characterized in that: be connected with connecting panel on the described five-way, be connected with the connection rocking arm on the described connecting panel, described connection rocking arm front end and the torque sensor pin joint that is fixed on the vehicle frame, connection rocking arm rear end is connected with the guide wheel with chain engages.
Described torque sensor mainly is made of lower bracket, stage clip, magnet and hall sensor on the stage clip of mutual slip, and described stage clip, magnet place on the stage clip upper bracket, and hall sensor places the stage clip lower bracket.
Beneficial effect: simple in structure, low cost, dependable performance, in light weight; By connect than length regulate or the adjusting of stage clip pressure assistant's effect of realize moment 1: 1 or 1: 2.Can save battery power, increase the distance of riding.

Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, flywheel, 2, chain, 3, crank wheel disk, 4, five-way, 5, connecting panel, 6, connect rocking arm, 7, torque sensor, 8, rotating shaft, 9, guide wheel, 10,11, lower bracket on the stage clip, 12, stage clip, 13, magnet, 14, hall sensor.
The specific embodiment
Below in conjunction with preferred embodiment, details are as follows to the specific embodiment that foundation the utility model provides, see accompanying drawing for details, a kind of Electrical Bicycle that has chain compressed spring type moment-assistant sensor, comprise bicycle axis chain gear system flywheel 1, chain 2, crank wheel disk 3 and be installed in five-way 4 on the vehicle frame, be connected with connecting panel 5 on the described five-way, described connecting panel by rotating shaft 8 be connected rocking arm 6 pin joints, described connection rocking arm front end and torque sensor 7 pin joints that are fixed on the vehicle frame, connection rocking arm rear end is connected with the guide wheel 9 with chain engages.Described torque sensor mainly is made of lower bracket on the stage clip of mutual slip 10,11, stage clip 12, magnet 13 and hall sensor 14, and described stage clip, magnet place on the stage clip upper bracket, and hall sensor places the stage clip lower bracket.
Principle of work: when riding, when foot-operated pedal drove crank wheel disk, the tension of chain top drove the guide wheel upward movement that connects on the rocking arm, and the other end that connects rocking arm is moved downward, and stage clip is stressed to be compressed.Magnet contacts with hall sensor and produces signal, is sent to the controller of Electrical Bicycle, and controller is received the signal power of inductor and supplied with current of electric, thereby realizes the moment-assistant effect.
