Abstract
The utility model relates to a self-luminous black screen instrument with capability of being free from influence of light of the outside, changeable colors and adjustable brightness. The utility model has a transparent cover which is organic glass with light transmittance of 10 percent to 30 percent; graduation and a pointer has the changeable colors; a light scattering plate is arranged under a dial plate with uniform graduation brightness; the pointer has a special light conducting plate. A driver can be free from the influence of natural light so as to clearly recognize vehicle travelling information displayed on the instrument, and an entire vehicle designer can arrange the position of the instrument conveniently.
Description
Technical field
The utility model relates to a kind of automobile-used indicating device, especially can show the combination instrument of running information when energising.
Background technology
The structure of present used auto meter is to adopt the colourless transparent plastic or the unorganic glass of high permeability to make the instrument face shield.(automobile is trip the lights not) instrument was not opened backlight when ambient light was strong by day, by extraneous light illumination, reading; (automobile is opened illuminating lamp) instrument backlight is bright when night, extraneous light was dark, and light sees through calibrated disc, helps the chaufeur reading.Since between daytime reading and night during reading the illuminating ray source of instrument different, design brings certain difficulty to car load.Particularly more weak and when not opening the instrument backlight at extraneous light, the instrument indication is clear inadequately, influences the normal reading of navigating mate.And instrument is when extraneous light illumination, the whole gauge panel comparison dullness that seems.
Summary of the invention
Be difficult to see clearly the deficiency of the information of vehicles that shows on the instrument a little less than and increase the readability of instrument in ambient light in order to overcome chaufeur, the utility model provides a kind of instrument, this instrument is not influenced by extraneous light in the time of can making the information of vehicles that chaufeur shows on observing instrument, can also allow design engineer when car load designs, can realize the variation of scale and pointer color and brightness, give car load with sensation luxurious and attractive in appearance, allow a kind of selections more than the main engine plants.
The technical scheme that its technical matters that solves the utility model adopts is: backlight is opened when automobile power source is connected, and makes scale, pointer and the mileage counter Chang Liang of instrument, and other warning designated symbols are bright or dark according to the automobile actual condition; In order to make brightness not be subjected to that ambient light is too big to be influenced, adopting transmitance is that 10%～30% organism glass is made the instrument face shield; The backlight illumination of instrument is regulated automatically according to the brightness of extraneous light.This just reaches the influence that chaufeur is not subjected to extraneous light power, can be clear that the information of vehicles that shows on the instrument at any time and be convenient to car load design-calculated purpose.Backlight may be selected to be redness, blueness, green, yellow and white LED, and break-make by controlling LED of all kinds and the size of current by LED of all kinds can make instrument demonstration backlight different color and brightness, satisfy the different vision requirement of chaufeur.Make scale brightness even by increase astigmatism plate below calibrated disc, the light that LED is sent with special-purpose leaded light prism is transmitted to the pointer root, makes pointer brightness very high.
The beneficial effects of the utility model are: automobile one energized dial of meter, pointer and corresponding warning indicator lamp are just luminous, dial of meter brightness is even, pointer brightness height, the scale of instrument and pointer can variable colors and are regulated brightness, and clear eye-catching, when reading information of vehicles, chaufeur can not be subjected to the interference of extraneous light power, and instrument can be arranged in the more weak place of extraneous light, bigger design space is provided for the car load design engineer, has embodied the design philosophy of hommization.
Description of drawings
Below in conjunction with embodiment the utility model is further specified.
Fig. 1 is the luminous circuit theory sketch of control scale and pointer illumination LED.
Fig. 2 is the elevation profile constructional drawing of an embodiment.
1. pointer caps among the figure, 2. pointer axle sleeve, 3. pointer, 4. translucent cover, 5. leaded light prism, 6. calibrated disc, 7. astigmatism plate, 8. inner cover, 9. stepping motor, 10. pointer illumination LED, 11. scale illumination LED, 12. printed electronic circuit plate member.
The specific embodiment
In Fig. 1, after various signals enter micro controller system, by the processing of SCM program, the extinguishing and light and strong and weak adjust (the PWM mode) of brightness finished following function of the light-emitting diode group of control different colours:
According to the night light signal adjust the panel color (for example, be that white panel is backlight daytime, when extraneous light a little less than, when car lighting lamp is opened, the instrument blueness that automatically switches to backlight).
2. according to the brightness of extraneous light automatic brightness adjustment calibrated disc, pointer, to adapt to the reading needs of chaufeur; Simultaneously can be by the light modulation button, the brightness of scale, pointer is put in order in the armrest wage adjustment, makes it the most suitable driver's individual requirement.
3. according to actual vehicle condition, make the pointer variable color, play more obvious prompt functions.For example: automobile is when nominal situation, and the color of pointer is a white; When automobile was operated in low oil mass, high water temperature and the high speed of a motor vehicle, the color of corresponding pointer became redness by original white, plays prompting, warning effect.
In the embodiment shown in Figure 2, light that pointer illumination LED (10) sends is earlier through the root that converges and be transmitted to pointer (3) that passes through leaded light prism (5) again that converges of inner cover (8), by the reflecting surface of pointer (3) root light distributed to needle body; The light that scale illumination LED (11) sends conducts light to calibrated disc (6) through the substep that passes through astigmatism plate (7) again that converges of inner cover (8) earlier; The light that scale and pointer send is the eyes that 10%～30% translucent cover (4) is mapped to chaufeur by light transmittance.
Claims (5)
1. automobile-used blank screen instrument, instrument face shield transmitance is that 10%～30% transparent plastic material is made, and is calibrated disc backlight and pointer backlight with LED, under calibrated disc astigmatism plate is arranged, the calibrated disc backlight is positioned at the astigmatism plate below, is the pointer leaded light with special-purpose leaded light prism.
2. auto meter according to claim 1 is characterized in that: adopting light transmittance is that 10%～30% transparent plastic material is made the instrument face shield.
3. auto meter according to claim 1 is characterized in that: adopt LED as calibrated disc and pointer backlight, LED Chang Liang when instrumentation.
4. auto meter according to claim 1 is characterized in that: under the calibrated disc astigmatism plate being arranged, is the pointer leaded light with special-purpose leaded light prism.
5. auto meter according to claim 1 is characterized in that: scale and pointer can be realized color, the brightness of conversion scale and pointer by the LED that assembles different colours, brightness according to customer requirements.
