Preferably, described infrared ray is kept away barrier sensor and is comprised infrared transmitting tube and infrared receiving tube, and when front has object to shelter from the infrared ray of infrared transmitting tube transmitting, described infrared receiving tube can accept the infrared ray be reflected back.
Preferably, described dwang is provided with row's perforation along the radius of gyration, described brake cable by being fixed on, different perforation regulates the stretching distance of brake cable.
Beneficial effect:
The invention provides a kind of bicycle dynamic brake system based on Hall element, solve the function that standard bicycle does not have self-braking, whole scheme is simple, and cost is lower, makes the traveling of bicycle safer, has and well promote effect.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of bicycle dynamic brake system;
Fig. 2 is steering wheel and dwang structural representation;
Fig. 3 is bicycle dynamic brake system principle diagram.
Detailed description of the invention
For making the object of the embodiment of the present invention, technical scheme and advantage clearly, be clearly and completely described below to the technical scheme in the embodiment of the present invention, obviously, described embodiment is the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Embodiment 1:
As shown in Figure 1, a kind of bicycle dynamic brake system based on Hall element, comprise: barrier sensor 1 kept away by infrared ray, Hall element 2, magnet 3, micro controller system, steering wheel 3, dwang 4, brake cable and power module, described infrared ray keeps away barrier sensor setting in the first pipe front end of headstock, on the front fork that described Hall element is arranged on bicycle and back vent, described magnet is arranged on position relative with Hall element on vehicle wheel spoke, described dwang 4 one end is fixedly connected with the output shaft of steering wheel 3, the other end is connected with brake cable, described power module is that barrier sensor kept away by infrared ray, Hall element micro controller system and steering wheel are powered, described micro controller system connects infrared ray and keeps away barrier sensor, Hall element is connected with steering wheel, the relative distance of described magnet and Hall element is 3-5mm, described bicycle dynamic brake system is also provided with touch-switch, described touch-switch is arranged on the position near holds cover on handlebar, described touch-switch is connected with micro controller system, described infrared ray is kept away barrier sensor and is comprised infrared transmitting tube and infrared receiving tube, when front has object to stop, because the penetrating capacity of infrared light is more weak, now infrared receiving tube receives infrared light, when front does not have object, infrared light emission is gone out and is not reflected, and infrared receiving tube does not receive infrared light, now just forms two states, is detected this two states by micro controller system, just can judge whether front has obstacle.Described dwang 4 is provided with a row along the radius of gyration and bores a hole 5, described brake cable by being fixed on, different perforation 5 regulates the stretching distance of brake cable, because the radius of gyration of different perforation 5 correspondences is different, the arc length turning over same angle is not identical yet, therefore brake cable is made to have different stretching distances, as shown in Figure 2.
It should be noted that, as shown in Figure 3, whether barrier sensor detection bicycle front kept away by infrared ray has obstacle, Hall element detects the front-wheel of bicycle and the rotating speed of trailing wheel, and all send obstacle signal and tach signal to micro controller system, when preceding object thing signal being detected, micro controller system judges rotating speed whether below setting value, if exceed, then Single-chip Controlling steering wheel work, the output shaft of steering wheel drives dwang, dwang pulls brake cable, thus make bicycle be decelerated to below setting value, if be no more than, then steering wheel is failure to actuate, setting value is the safe low speed driving speed of bicycle, generally in the scope of 0.1-1m/s.
Described touch-switch has two gears, for switching different braking modes: the setting value that two kinds of braking modes are corresponding different, can decelerate in various degree, and in order to prevent the situation of locking wheel, setting is all greater than 0m/s.
The invention provides a kind of bicycle dynamic brake system based on Hall element, solve the function that standard bicycle does not have self-braking, whole scheme is simple, and cost is lower, makes the traveling of bicycle safer, has and well promote effect.
Above embodiment only in order to technical scheme of the present invention to be described, is not intended to limit; Although with reference to previous embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of various embodiments of the present invention technical scheme.
