Background technology
Under the development situation that current electronic product is advanced by leaps and bounds, the variation of making rapid progress has also taken place in automobile instrument thereupon.The function of instrument has been not only indication, and the speed of a motor vehicle, rotating speed, water temperature, fuel oil etc. can both show for the driver by combination instrument understands whole vehicle condition.Simultaneously conveniently check the information that shows on the combination instrument, so also adopted a large amount of LED lamps on the instrument, panel board backlight, the backlight and signal lamp of liquid crystal etc. in order to throw light on.But the present automobile instrument monochrome that is backlight only is the effect of playing illumination, does not possess the function of vehicle speed alarm.
Summary of the invention
The purpose of this utility model is to have the problems referred to above at existing technology, can change the combination instrument that changes with the speed of a motor vehicle backlight with vehicle speed alarm function with the variation of the speed of a motor vehicle thereby proposed a kind of simple in structure and its backlight color.
The purpose of this utility model can realize by following technical proposal: a kind of combination instrument that changes with the speed of a motor vehicle backlight, comprise instrument controller and the vehicle speed sensor that is connected with instrument controller, described vehicle speed sensor can detect vehicle speed signal and vehicle speed signal is transferred to instrument controller, it is characterized in that: also be provided with the illuminating circuit that is connected with instrument controller in this combination instrument, the vehicle speed signal that described instrument controller can will receive from vehicle speed sensor compares to be analyzed and sends different control signals according to Different Results and give illuminating circuit, and described illuminating circuit can receive above-mentioned control signal and send the light of different colours according to the difference of control signal.
What illuminating circuit sent different colours only is used for the instrument back light, not only plays the effect of illumination, can also convey to some speed informations of driver by the difference of backlight color very intuitively.
In the above-mentioned combination instrument that changes with the speed of a motor vehicle a kind of backlight, described instrument controller comprises signal input unit, storage unit, comparing unit and signal output unit, and signal input unit, storage unit and signal output unit all are connected with comparing unit.
Some can be set speed information in advance is stored in the storage unit, after instrument controller receives actual vehicle speed information from vehicle speed sensor, these actual vehicle speed information are transferred in the comparing unit by signal input unit, and comparing unit is set speed information and compared to analyze and produce control signal according to the comparative analysis result and send to illuminating circuit by signal output unit with originally being stored in by the actual vehicle speed information that receives in the storage unit.
In the above-mentioned combination instrument that changes with the speed of a motor vehicle a kind of backlight; described illuminating circuit comprises the luminescence unit of several connections parallel with one another; each luminescence unit includes protective resistance R and several light emitting diodes; protective resistance R is connected with above-mentioned instrument controller; identical and series connection its plus earth of back successively of the anode and cathode direction of each light emitting diode; its anode is connected with protective resistance R; light emitting diode on the same luminescence unit sends the light with a kind of color, and the light emitting diode of different luminescence units can send the light of different colours.
The principle of light that instrument controller control illuminating circuit sends different colours is as follows: when instrument controller is controlled lumination of light emitting diode on certain luminescence unit according to the needs as a result of comparative analysis, this moment, instrument controller can be given this luminescence unit one high level, the voltage that be added on the anode and cathode of each light emitting diode this moment is forward voltage, lumination of light emitting diode; What other luminescence unit instrument controllers provided is low level, and light emitting diode is all not luminous.
In the above-mentioned combination instrument that changes with the speed of a motor vehicle a kind of backlight, described light emitting diode is the LED lamp, its LED lamp comprises white led lamps, green LED lamp, blue led lamp, yellow LED lamp and red LED lamp, and the LED lantern festival of different colours is sent the light of corresponding different colours.
LED lamp on the corresponding different luminescence units of the detected different actual vehicle speed of vehicle speed sensor lights.For example: in storage unit, store 0km/h, 60km/h, 80km/h, 100km/h and 120km/h etc. in advance and set speed information, instrument controller will compare analysis from actual vehicle speed information and above-mentioned these setting speed informations that vehicle speed sensor receives, if its comparative result speed of a motor vehicle is 0 between 60km/h the time, the control white led lamps is bright; If the speed of a motor vehicle is when 60km/h is between 80km/h, the control green LED lamp is bright; If the speed of a motor vehicle is when 80km/h is between 100km/h, control blue led lamp is bright; If the speed of a motor vehicle is when 100km/h is between 120km/h, the control yellow LED lamp is bright; When if the speed of a motor vehicle surpasses 120km/h, the control red LED lamp is bright.Like this, the combination instrument backlight color can change along with the variation of the speed of a motor vehicle, and the chances are is in the speed of a motor vehicle of what level by watching the combination instrument backlight color just can easily recognize the present speed of a motor vehicle intuitively for the driver, has the vehicle speed alarm function.
Compared with prior art, this combination instrument is provided with illuminating circuit, this illuminating circuit can change along with the variation of the speed of a motor vehicle, the effect that not only has illumination, and make the driver as long as by watching the combination instrument backlight color just can recognize the general situation of the present speed of a motor vehicle easily and intuitively, have the vehicle speed alarm function.This combination instrument is simple in structure, and is easy to use, directly perceived.
Description of drawings
Fig. 1 is a structure principle chart of the present utility model.
Embodiment
Below be specific embodiment of the utility model and in conjunction with the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.
As shown in Figure 1, this combination instrument that changes with the speed of a motor vehicle backlight comprises instrument controller and the vehicle speed sensor that is connected with instrument controller, illuminating circuit, vehicle speed sensor can detect vehicle speed signal and vehicle speed signal is transferred to instrument controller, the vehicle speed signal that instrument controller can will receive from vehicle speed sensor compares to be analyzed and sends different control signals according to Different Results and give illuminating circuit, and illuminating circuit can receive control signal and send the light of corresponding different colours according to the difference of control signal.
