Abstract
The utility model provides an electromechanical automobile and motorcycle speed odometer. The odometer comprises a signal converting device, a printed wiring board, a signal treatment circuit, a liquid crystal display counter and a speed indicator, wherein the signal converting device comprises a magnet and a signal sensor arranged on one side of the magnet, the magnet is fixed with a rotating shaft and is arranged on the upper portion of a chassis, the printed wiring board is arranged between the chassis and a dial, the signal treatment circuit is made up of electron devices arranged on the printed wiring board, and the liquid crystal display counter is connected with the signal treatment circuit. The odometer removes a gear driving element and sensing cover when recording the mileage of the automobile and indicating the speed of the automobile, thoroughly solves the problem that the gear grinding hair fastener and the sensing cover of the conventional technique does not indicate stably and accurately through driving the needle pointer to rotate, overcomes the deficit existing in the conventional technique, thereby having the advantages of simple and novel structure, easy manufacturing arc, accurate indicating, stable production quality, reliable working property, extensive application prospect, fitness of spreading and applied and the like.
Description
Technical field: the utility model relates to a kind of speedometer of motor vehicle, particularly relates to a kind of speedometer that is installed on automobile and the motorcycle.
Background technology: speedometer is the indicating instrument that is used to refer to motor vehicle speed in the process of moving and writes down the mileage that is travelled, so it is the key indicating instrument that must dispose on automobile and the motor.Existing automobile and motorcycle speedometer major part is taked mechanical structure, and it is to be connected with automobile by rotating shaft, and drives the character wheel rotation of the mechanical counter in the instrument by the tertiary gear transmission, thereby writes down the mileage of running car.The speed indication then is that the induction cover drive pointer of punch process rotates the speed realization of indicating running car.Its structure of the speedometer of this mechanical structure and complex process, part precision are difficult for guaranteeing that the pointer indication is not steady, gear weares and teares in transmission process greatly, easily causes the gear hair fastener, makes the instrument indication inaccurate, even lost efficacy, cause the product quality performance unreliable.
Summary of the invention: the utility model is for a kind of electromechanical automobile and motorcycle speedometer is provided, mainly be to solve structure and the complex process that exists in the prior art, part precision is difficult for guaranteeing, the pointer indication is not steady, gear weares and teares in transmission process greatly, easily cause the gear hair fastener, make the inaccurate or inefficacy of instrument indication, thereby cause the insecure problem of product quality performance.
Scheme of the present utility model is as described below: this utility model comprises rotating shaft, base, magnet, dial plate, also comprises signal transducer, stabilized voltage supply, liquid crystal display counter, speed indicator, reaches by memory IC
1, central controller IC
2, integrated circuit (HC7404) IC

9The signal processing circuit of forming, it is by the top at base the magnet that is connected and fixed with rotating shaft to be set, the chromacoder of forming with the signal transducer that is provided with in a side of magnet, and between base and dial plate, be provided with printed-wiring board (PWB) and the signal processing circuit of forming by the electron device on the printed-wiring board (PWB) and reach that the liquid crystal display counter that is connected with signal processing circuit and speed indicator realize.
The beneficial effects of the utility model: this utility model is owing to taked said structure, particularly be provided with and the fixing magnet of rotating shaft in gauge internal, the chromacoder of forming with the signal transducer corresponding with magnet, add signal processing circuit and the liquid crystal display counter that is connected with signal processing circuit and the combination of speed indicator, making this utility model cancel gear transmission part when the speed of mileage that writes down running car and indication running car covers with induction, thereby solved gear wear hair fastener and induction cover and driven the not steady inaccurate key technical problem of pointer rotation indication, overcome the deficiencies in the prior art, and had novelty simple in structure, manufacture craft is easy, the instrument indication accurately, constant product quality, reliable working performance, have a extensive future, advantage such as be fit to apply.
Description of drawings:
Fig. 1 is electromechanical automobile and motorcycle speedometer one-piece construction figure;
Fig. 2 is the dial plate synoptic diagram of electromechanical automobile and motorcycle speedometer;
Fig. 3 be electromechanical automobile and motorcycle speedometer circuit diagram.
Embodiment: by Fig. 1-its base 1 center of electromechanical automobile and motorcycle speedometer shown in Figure 3 is rotating shaft 2, be provided with the magnet of fixing with rotating shaft 23 at the top of base 1, magnet 3 one side settings are the signal transducer 4 of correspondence with it, and constitutes chromacoder by rotating shaft 2, magnet 3, signal transducer 4.Signal transducer 4 can be Hall element or tongue tube.To be signal output part be connected with signal processing circuit 6 input ends on the printed-wiring board (PWB) 5 at the two ends of signal transducer 4, printed-wiring board (PWB) 5 is arranged between base 1 and the dial plate 7, liquid crystal display counter 8 and speed indicator 9 that printed-wiring board (PWB) 5 is provided with two groups of stabilized voltage supplys, signal processing circuit 6 and is connected with signal processing circuit 6.Wherein one group of stabilized voltage supply provides for signal transducer 4, and another group stabilized voltage supply is to provide stable working power for signal processing circuit 6, liquid crystal display counter 8 and speed indicator 9.Its circuit part is known circuit.
When automobile and motorcycle travels, rotating shaft 2 drives magnet 3 and rotates, the magnetic pole N utmost point of magnet 3, the S utmost point are at the induction end checker of signal transducer 4, signal transducer 4 of every conversion is just exported a pulse signal, pulse signal is sent into liquid crystal display counter 8 and speed indicator 9 demonstrations and indication respectively after handling (comprising amplification, storage, memory, output control etc.) by signal processing circuit 6.Thereby realize mileage, speed purpose of indicating.
