Abstract
The utility model discloses a digital display dial plate for electronic tachometer of engine, comprising an arc-shaped array of light emitting diodes, a displayer with two-bit digital codes, night vision light emitting diodes, alarming strobe light emitting diodes, and a surface plate, wherein, the arc-shaped array of light emitting diodes is provided with digital scales. In the utility model, the digital scales from the arc-shaped array of light emitting diodes and the two-bit digitals of the displayer with two-bit digital codes form synchronous indication of the rotation speed of engines simulation and the rotation speed of digitals. The position of the indicating scale values is illuminated by the night vision light emitting diodes, and the flicker of the alarming light emitting diodes indicates over speed. The light emitting diodes of the arc array can be divided into rotation speed sections of different colors. The utility model has the advantages of accuracy, direct view, beautiful appearance, and high reliability.
Description
The utility model is the digital display dial plate that belongs to the Motronic control maps tachometer gage.
For adapting to the modern needs of auto industry, the Motronic control maps tachometer gage is applied at large, but there is short shortcoming of tachometer gage life-span in its display mode still based on the pattern of mechanical pointer.Chinese patent " automobile instrument of dual demonstration also has attention display " (90226003), be still synchronous light belt demonstration and the critical value alarm indication of increase on common pointer instrument, and for example the electronic tachometer of imported auto VDO company also is that pointer-type shows.Motronic control maps tachometer gage digital display dial plate of the present utility model, design is to adopt with the light emitting diode arc shooting array of digital indicating graduation and double figures character code display to simulate synchronous demonstration with two digits, just have array simulation intuitive display and numeral and show the advantage that readability combines, can substitute pointer dial plate, and have directly perceived, the feature of attractive in appearance and readability.
The purpose of the utility model design is in order to overcome the deficiency of mechanical pointer engine speed indicator, and the dial plate of design electronic tachometer shows with the analog digital combination, can substitute the indication that the pointer electron tachometer gage is made engine speed.
For achieving the above object, the novel structure and the new technology measure of the utility model design are as follows: Motronic control maps tachometer gage digital display dial plate is the variation by the generator voltage frequency, signal after digital circuit is handled is done simulation and the synchronous terminal demonstration of two digits combination by light emitting diode arc shooting array that has digital indicating graduation and two digits display.This light emitting diode arc shooting array and corresponding with it band numeral indicating graduation, design increases or reduces the quantity that shows the corresponding tachometer value of light emitting diode with the increase or the minimizing of engine speed, and do simulation by corresponding scale value and show, do to be synchronized with the numeral demonstration of rotating speed simultaneously with double figures character code display.In addition, also according to the section of engine speed, design is represented different rotating speed sections with varicolored light emitting diode, and respectively the numeral of indicating graduation is illuminated by some light emitting diodes at the night vision state, and design is done flicker by a light emitting diode and is shown when engine arrives the warning rotating speed.
Below with embodiment and close accompanying drawing and be elaborated as follows to Motronic control maps tachometer gage digital display dial plate:
Fig. 1 is the combination assumption diagram of Motronic control maps tachometer gage digital display dial plate.
As shown in Figure 1, Motronic control maps tachometer gage digital display dial plate, it by the light emitting diode arc shooting array 1 that is positioned at the digital indicating graduation of surface plate 5 upper left bands, be positioned at surface plate 5 bottom-right double figures character code displays 2, the night vision light emitting diode 3 that illuminates the indicating graduation numeral, racing of the engine warning strobe light emission diode 4 and surface plate 5 and form.Described digital display dial plate is made of the synchronous digital display indicating structure of simulation of engine rotating speed and digital rotating speed the two digits of digital indicating graduation of the band of light emitting diode arc shooting array 1 and double figures character code display 2, and night vision light emitting diode 3 and light emitting diode arc shooting array 1 indicated digital indicating graduation is connected, and warning strobe light emission diode 4 is connected with the hypervelocity numerical code of double figures character code display 2 and forms the indicating structure of Motronic control maps tachometer gage digital display dial plate.Wherein light emitting diode arc shooting array 1 be one with digital indicating graduation and be arranged in the light emitting diode array of the curved arrangement in upper left side of surface plate 5, its array is divided into the rotating speed section of different color, and the designation number of array scale is connected with night vision light emitting diode 3.Double figures character code display 2 is arranged in the lower right of surface plate 5, and the hypervelocity value of its numerical code is connected with warning strobe light emission diode 4.
In a word, digital display dial plate by this implementation column manufactures and designs just can become the combination of simulation and two digits to show the rotating speed of engine synchronously with double figures character code display combinations by the light emitting diode arc shooting array that has digital indicating graduation in conjunction with digital circuit.The utility model can also be applied in other field, as speed, the isoparametric analog digital combination of pressure and temperature are shown, makes it to have directly perceived, attractive in appearance and highly reliable characteristics.
