Abstract
The utility model discloses an electric bicycle middle shaft with a power assisting sensor device. The technical scheme is that the electric bicycle middle shaft comprises a middle shaft and a circuit board, the middle shaft penetrates through a sleeve, a plastic disc is installed on the middle shaft in an interference fit mode, and a magnet is inlayed in the plastic disc. A Hall element is welded on the circuit board which is fixed on the inner circumferential face of the sleeve. The electric bicycle middle shaft with the power assisting sensor device achieves the fact that the power assisting sensor device is installed in the integrated middle shaft under the condition that international standard bicycle middle shaft size and five-way size are not changed. The middle shaft drives the plastic disc to rotate, the magnet rotates relative to the Hall element, and the Hall element senses a magnetic field signal and outputs a pulse signal.
Description
Technical field
The utility model relates to the Electrical Bicycle field, more particularly, relates to a kind of Electrical Bicycle axis with assistant sensor device.
Background technology
When manpower is ridden Electrical Bicycle, through the size of detection pedal power, or through detecting the speed of pedal speed; Be transferred to controller to these detection signals; Give a certain proportion of electrical drive power of motor by controller, thereby realize the driven in common of manpower and electric power, reach power-assisted effect.
The Electrical Bicycle industry detects the assistant sensor of pedal speed speed at present, adopts Hall element mostly.Hall element is fixed on vehicle frame axis position.The vinyl disc of inlaying magnet steel is fixed on axis or the wheel disc.When manpower drove the trailing wheel rotation through pedal, vinyl disc and axis or wheel disc rotated synchronously, and the drive magnet steel rotates synchronously.Hall element is a kind of magneto sensor, when magnet steel near or away from Hall element the time, Hall element is exported corresponding high potential or end current potential.When magnet steel rotates with vinyl disc, magnet steel is near Hall element the time, Hall output high potential, and when magnet steel the time away from Hall element, Hall element output active potential.The vinyl disc of band magnet steel will be installed on the axis, and the circuit of band hall sensing head needs support to be fixed on the five-way end face.The middle shaft size and the five-way size of bicycle are the range of sizess that meets international standard, and the wheel disc that is installed on the axis also is single speed wheel disc or the multi-change speed wheel disc that meets international standard.For the multi-change speed wheel disc, therefore wheel disc just cannot install vinyl disc apart from 3 millimeters of the gap deficiencies of five-way end face on axis.
The utility model content
The utility model technical matters to be solved is, overcomes the deficiency that exists in the prior art, and a kind of Electrical Bicycle axis with assistant sensor device is provided.
The utlity model has the Electrical Bicycle axis of assistant sensor device, be achieved, comprise axis and wiring board through following technical proposals; It is characterized in that; Said axis passes sleeve, and the vinyl disc interference fit is installed on the axis, and magnet is embedded in the vinyl disc; Hall element welds in the circuit board, and wiring board is fixed on the sleeve inner peripheral surface.
Said wiring board connects light-emitting diode.
The utility model has been realized not changing under the situation of bicycle middle shaft size and five-way size of international standard, and the power-assisted sensing device is installed in the one axis.Axis drives the vinyl disc rotation, and the relative Hall element of magnet rotates Hall element magnetic field sensor signal output pulse signal.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the sensor circuit figure that Hall element is installed.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done and to be further described.
As shown in Figure 1, said axis 4 passes sleeve 5, and vinyl disc 2 interference fit are installed on the axis 4, and magnet is embedded in the vinyl disc; Hall element is welded on the wiring board 3, and wiring board is fixed on the sleeve inner peripheral surface, and the axis two ends are provided with left side nut 1 and right side nut 6.
Fig. 2 is the sensor circuit of two Hall elements, T1 wherein, and T2 is Hall element (a plurality of Hall elements can be set as required).U1 is the micro controller system in the wiring board, and D1 is mounted in the light-emitting diode (wiring board connection light-emitting diode) on the sensor outer housing, is used to indicate output pulse signal, and personnel convenient for assembly or maintainer detect output signal.
Embodiment recited above describes the utility model preferred implementation; Be not that design and scope to the utility model limits; Under the prerequisite that does not break away from the utility model design philosophy; Common engineering staff make the technical scheme of the utility model in this area various distortion and improvement all should belong to the protection domain of the utility model.
Claims (2)
1. the Electrical Bicycle axis with assistant sensor device comprises axis and wiring board, it is characterized in that said axis passes sleeve, and the vinyl disc interference fit is installed on the axis, and magnet is embedded in the vinyl disc; Hall element welds in the circuit board, and wiring board is fixed on the sleeve inner peripheral surface.
2. the Electrical Bicycle axis with assistant sensor device according to claim 1 is characterized in that, said wiring board connects light-emitting diode.
