Abstract
The utility model aims to provide an indicator which can directly display the digital of vehicle speed and distance for bicycle users, composed of a signal generator which is composed of a magnetic body mounted on the bicycle and a coil mounted on a bicycle frame, a complete electronic data-processing apparatus, and a digital displayer. The counter of the data-processing apparatus counts signals generated from the signal generator, so that the vehicle speed and distance can be indicated conveniently. Meanwhile, the utility model can be used on other kinds of vehicles whose vehicle speed and distance need indicating, such as automobiles, motorcycles, etc.
Description
The utility model belongs to electronic measuring instrument.
At present on general power car such as vehicles such as automobile, motorcycle, car speed, distant-indicator are housed all generally, this indicator generally is mechanical, so complex structure, cost height and poor reliability, life-span are short.Special needs to be pointed out is, also find no similar indicator using on the extremely general bicycle.
The utility model is intended to provide for the bicycle user speed by bike and the distant-indicator of a direct digital display.
It is by a vehicle wheel rotational speed--and electric signal sensor 1, a full-electronic data processing equipment 2 and a digital indicator 3 are formed.
Wherein sensor is to be made of the coil 5 that is fixed on the Armco magnetic iron 4 on the wheel and be fixed on the vehicle frame, when wheel 6 rotates, just goes out electric signal at the coil internal induction that is fixed on the vehicle frame.The full-electronic data processing equipment becomes corresponding pulse signal with this electrical signal conversion, by an electronic counter this pulse signal is counted, and can indicate range information.Simultaneously can produce a unit interval signal strobe, pulse signals is counted and can be indicated velocity information gate time in this scope.
Fig. 1 is a theory diagram of the present utility model, and Fig. 2 is the structural representation of sensor 1.
Fig. 3 is the internal logic block diagram of full-electronic data processing equipment 2.Wherein 7 issue device, 12 and be code translator for register, 14 for logic gates, 13 for dividing for clock generator, 11 for speed counter, 10 for range counter, 9 for pulse shaping circuit, 8.
When range of a signal, the electric signal that is sent by electric signal sensor 1 is shaped as the standard logic level signal through shaping circuit 7, and this signal counter of adjusting the distance is counted, and has promptly delivered to digital indicator and demonstrates range information through depositing, deciphering then.
When display speed, issue circuit 11 by clock circuit 10 through branch and produce a unit interval signal strobe, the signal of this signal and shaping circuit 7 outputs is counted the speed counter through logic gates 12 after, through after deposit, deciphers and promptly delivers to digital indicator 3 and demonstrate velocity information.Above-mentioned distance, speed show and can select by K switch.
Simple in structure for making, easy to use, the electric signal that the power supply of above-mentioned indicator can directly be exported by sensor provides, and perhaps uses solar cell.
Be saves energy, above-mentioned digital indicator can be used LCD.Simultaneously, above-mentioned full-electronic data processing equipment can be designed to special-purpose COMS integrated circuit, and can add various functions easily.For example add digital clock to show temporal information.
The utility model can directly be fixed on the bicycle halter, Yi Bian Yi Bian the cyclist just can read present speed by bike and distance by bike easily.
The utility model available use simultaneously is on other vehicle, and routine automobile, motorcycle etc. only need that the structure class of sensor is done variation this moment and get final product.When use is of the present invention on taxi, can directly utilize existing distance, time data, in the full-electronic data processing equipment, add and will exercise distance, reach the circuit that waiting time converts expense to, make to replace the taxi log.
The utility model is reasonable in design, and is simple in structure, and power consumption is little, and cost is low, and the reliability height is a kind of desirable electronic vehicle speed, and range indicator can be widely used in various need to the indication on the vehicle of road speed and distance.
