A kind of double managing devices that test the speed on electric bicycleTechnical field
It the utility model is related to electric bicycle field, more particularly to a kind of double management of testing the speed on electric bicycleDevice.
Background technology
At present, there was only a tachogenerator on electric bicycle, can only so test the speed of a wheel, work as generationSkid or bring to a halt, wrestling etc. when car can also not stop, security cannot be guaranteed.
Utility model content
The purpose of the utility model is:In view of the above-mentioned problems, the utility model provides a kind of pair on electric bicycleTest the speed managing device, monitors electric bicycle running status in real time, ensures safe operation.
The technical solution of the utility model is:
A kind of double managing devices that test the speed on electric bicycle, including controller and connected first speed of differenceDegree sensor and second speed sensor, the First Speed sensor and second speed sensor are respectively arranged in electrical salf-walkingThe front wheels and rear wheels of car, for testing the rotating speed of front wheels and rear wheels, and controller is sent to, controller is according to front wheels and rear wheelsRotating speed judges electric bicycle running status, and controlled motor operating condition.
Preferably, the front wheels and rear wheels of the electric bicycle are respectively follower and driving wheel.
Preferably, the First Speed sensor and second speed sensor use Hall sensor.
Preferably, when the rotating speed of the front wheels and rear wheels is equal, electric bicycle normal operation, controller controlled motor is justOften operating, otherwise controlled motor shuts down.
The utility model has the advantages that:
Double managing devices that test the speed that what the utility model was proposed be used on electric bicycle, using controller and respectively withTwo velocity sensors of the rotating speed of its test front wheels and rear wheels connected, controller judge electricity according to the rotating speed of front wheels and rear wheelsWhether dynamic bicycle skids, brings to a halt, the situation such as wrestling, and controlled motor stops operating in time, to prevent there is car handlePeople throws away, and boosting can shut down to restart when climbing when testing out skidding can effectively climb up slope, substantially increase safetyProperty with it is intelligent.
Brief description of the drawings
Below in conjunction with the accompanying drawings and embodiment is further described to the utility model:
Fig. 1 is the schematic diagram of double managing devices that test the speed described in the utility model on electric bicycle.
Embodiment
As shown in figure 1, the double managing devices that test the speed being used on electric bicycle disclosed in the utility model, including controlDevice and respectively connected First Speed sensor and second speed sensor, the First Speed sensor and second speedSensor is respectively arranged in the front-wheel of electric bicycle(Follower)And trailing wheel(Driving wheel), for testing turning for front wheels and rear wheelsSpeed, and controller is sent to, controller judges electric bicycle running status, and controlled motor according to the rotating speed of front wheels and rear wheelsOperating condition.
When the rotating speed of the front wheels and rear wheels is equal, electric bicycle normal operation is judged, controller controlled motor is normalOperating;When the rotating speed of the front wheels and rear wheels is unequal, judge that electric bicycle may skid, bring to a halt, the shape such as wrestlingCondition, controlled motor shut down.
The First Speed sensor and second speed sensor use Hall sensor, greatly improve test the speed sensing away fromFrom.
For above-described embodiment only to illustrate technical concepts and features of the present utility model, its object is to allow be familiar with techniquePeople can understand content of the present utility model and implement according to this, the scope of protection of the utility model can not be limited with this.It is allThe modification done according to the Spirit Essence of the utility model main technical schemes, it should all cover in the scope of protection of the utility modelWithin.
