Abstract
The invention discloses an instrument for a motor vehicle, which comprises a shift display, a backlight illuminating circuit, an instrument pointer, and an instrument panel, wherein the backlight illuminating circuit comprises an illuminating lamp circuit, a diode and a resistor, the an illuminating lamp circuit is divided into a plurality of branch circuits, each branch circuit comprises a lighting bulb, the lighting bulb of each branch circuit is connected with a shift controller positioned at an engine, a main line of the an illuminating lamp circuit is connected with the negative electrode of the diode, and the positive electrode of the diode is connected with the resistor and a power supply in sequence. The invention adopts that the backlight illuminating circuit of the instrument of the motor vehicle is connected with a shift controller circuit of the motor vehicle, thus different colors of backlights are triggered to emit light when the shift is adjusted to remind a driver of noticing the driving speed, thereby reducing traffic accidents.
Description
Technical field
The invention belongs to vehicular meter and make the field, relate in particular to a kind of motor vehicle instrument.
Background technology
Vehicular meter generally includes: parts such as meter housing, movement, meter hand, instrument dial plate, gearshift display device and backlight; When chaufeur during at night travel, start the power supply of backlight, observe data on the specified instrument dial plate of each meter hand by the light of backlight, for example; The moving velocity of Fuel Oil Remaining of vehicle etc. and the shown vehicle of gearshift display device, the moment is grasped the motoring condition of vehicle.
The background light that is positioned at instrument only adopts the solid color illuminating lamp to throw light on, and can not change with the speed stage of vehicle and sends the light of different colours, and the illuminating lamp function ratio is more single.
Summary of the invention
Technical matters to be solved by this invention provides a kind of motor vehicle instrument, when the speed stage of vehicle changes, is communicated with the illuminating lamp of different colours, thereby the prompting chaufeur is noted car speed, reduces the generation of traffic accident.
In order to address the above problem, the present invention takes following technical scheme: a kind of motor vehicle instrument, comprise: gearshift display device, the backlight lighting circuit, meter hand and instrument dial plate, it is characterized in that, described backlight lighting circuit comprises: lighting lamp circuit, diode and resistance, described lighting lamp circuit is divided into a plurality of branch roads, and each branch road comprises a lighting bulb, the lighting bulb of described each branch road is connected with the gear controller that is positioned at the driving engine place, the main line of lighting lamp circuit is connected with the negative pole of diode, and the positive pole of diode is connected with power supply with resistance and is connected successively.
Preferably, described backlight lighting circuit is connected with gearshift display device, and gearshift display device is connected with gear controller.
Preferably, described illuminating lamp is a light-emitting diode.
Preferably, described gearshift display device is a LED charactron gearshift display device.
The present invention adopts the backlight lighting circuit with motor vehicle instrument to be connected with the gear controller circuit of power actuated vehicle, in regulation stall, the backlight that triggers different colours is luminous, chaufeur can be judged the speed stage of vehicle according to the color of backlight, when driving, note moving velocity, reduce the generation of traffic accident.
Description of drawings
Fig. 1 is described backlight and automobile gear level telltale, driving engine and gear controller bonded assembly structured flowchart;
Fig. 2 is the backlight principle of luminosity block diagram of present embodiment motor vehicle instrument;
Fig. 3 is backlight and gearshift display device junction circuit figure;

The specific embodiment
For above-mentioned purpose of the present invention, feature and advantage can be become apparent more, the present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
The gear controller 11 that please refer to Fig. 1 and Fig. 2 power actuated vehicle is connected with backlight 12 in the motor vehicle instrument, backlight is connected with gearshift display device 13, when chaufeur is selected different gears, light the backlight of different colours, gearshift display device shows corresponding gear, for example, when chaufeur is selected 1 gear, 1 gear and bus circuit bonded assembly switch closure are lighted with the red backlight conducting of 1 gear bonded assembly, show " 1 " with red backlight bonded assembly gearshift display device; When chaufeur was selected 2 gears, 2 gears and bus circuit bonded assembly switch closure were lighted with the blue backlight conducting of 2 gear bonded assemblys, show " 2 " with blue backlight bonded assembly gearshift display device; The gear controller of power actuated vehicle is connected with backlight also and is connected with driving engine 14, when gear controller is selected corresponding gear, simultaneously with the rotating speed gear conducting of backlight and driving engine, for example, when gear controller is selected 1 gear, the first gear conducting of driving engine, driving engine is selected the rotating speed of first gear, red backlight conducting is lighted, and gearshift display device shows " 1 "; When gear controller is selected 2 gears, the driving engine second gear conducting, driving engine is selected the rotating speed of second gear, and blue backlight conducting is lighted, and gearshift display device shows " 2 ".
As shown in Figure 3 and Figure 4, the LED gearshift display device is connected with the backlight circuit, according to the individual event conducting effect of diode, when the gear of gear controller selector motor vehicle is 1 grade, backlight 31 is lighted, and simultaneously, a of gearshift display device, d, e, f, g light-emitting diode extinguish; When the gear of gear controller selector motor-car two was 2 grades, backlight 31 was lighted, and simultaneously, the c of gearshift display device and f light-emitting diode extinguish; Need to prove,, select each gear correspondence to light a kind of backlight of color, also can select a plurality of gear correspondences to light the backlight of same kind of color according to different power actuated vehicle manufacturers' requirement.
Backlight in the motor vehicle instrument of the present invention adopts light emitting diode bulb, can reduce because the heat of the luminous generation of bulb to the damage of electronics package in the instrument, prolongs the service life of instrument.
More than motor vehicle instrument provided by the present invention is described in detail, used specific case herein principle of the present invention and embodiment are set forth, the explanation of above embodiment just is used for helping to understand method of the present invention and core concept thereof; Simultaneously, for one of ordinary skill in the art, according to thought of the present invention, the part that all can change in specific embodiments and applications, in sum, this description should not be construed as limitation of the present invention.
