Abstract
The utility model discloses a motor-driven vehicle instrumentation which includes: a shift display, a backlight lighting circuit, an instrumentation pointer and an instrumentation dial. The backlight lighting circuit includes: a lighting lamp circuit, a diode and an electric resistance, the lighting lamp circuit is divided into a plurality of branch circuits, each branch circuit contains a lighting bulb, the lighting bulb of each branch circuit connects with a shift controller located on a motor, a main circuit of the lighting lamp circuit connects with a cathode of the diode, an anode of the diode connects with the electric resistance and an electrical power source in orderly. The motor-driven vehicle instrument uses a circuit connection between the backlight lighting circuit of the motor-driven vehicle instrument and the shift controller of the motor-driven vehicle, which touch the backlight lamp with various color lighting when shift is adjusted simultaneously. The various light awakes driver train movement speed, and reduces traffic accident.
Description
Technical field
The utility model belongs to vehicular meter and makes the field, relates 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, gear telltale 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 gear telltale, 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.
The utility model content
Technical problem to be solved in the utility model provides a kind of motor vehicle instrument, when the speed threshold 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 utility model is taked following technical scheme: a kind of motor vehicle instrument, comprise: gear telltale, backlight lighting circuit, meter hand and instrument dial plate, 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 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 the gear telltale, and the gear telltale is connected with gear controller.
Preferably, described illuminating lamp is a light-emitting diode.
Preferably, described gear telltale is a LED charactron gear telltale.
The utility model adopts the backlight lighting circuit with motor vehicle instrument to be connected with the gear controller circuit of power actuated vehicle, when regulating gear, the backlight that triggers different colours is luminous, chaufeur can be judged the speed threshold 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 vehicle gear 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 gear telltale junction circuit figure;

The specific embodiment
For above-mentioned purpose of the present utility model, feature and advantage can be become apparent more, the utility model is described in further detail 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 gear telltale 13, when chaufeur is selected different gears, light the backlight of different colours, the gear telltale 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 gear telltale; 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 gear telltale; 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 the gear telltale 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 the gear telltale shows " 2 ".
As shown in Figure 3 and Figure 4, LED gear telltale 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 gear telltale, 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 gear telltale 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 utility model motor vehicle instrument 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 utility model is described in detail, used specific case herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment just is used for helping to understand method of the present utility model and core concept thereof; Simultaneously, for one of ordinary skill in the art, according to thought of the present utility model, the part that all can change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.
