Abstract
The utility model provides an automatic regulating apparatus is shaded in car, relates to the vehicle with the portable lighting device field of non -. This automatic regulating apparatus is shaded in car, utilize little light sensor connection control unit car in the bias light adjust, need not manually, can the vehicle realize automatically according to the regulation of light power in the car to the luminance of bias light, this structure is not restricted by the lampet on off state, no matter whether the lampet opens all the luminance of can automatically regulated being shaded promptly, need not the dimmer switch, greatly reduced development cost, the complete set all can dispose, satisfies all kinds of consumer group's demands, need not to use CAN bus communication can realize automatically regulated, make the low -cost motorcycle type of low side still can satisfy the configuration demand, promote the competitiveness.
Description
Technical field
The utility model relates to the non-portable field of illuminating device of vehicle, particularly automatic backlight adjusting device in a kind of car.
Background technology
The high vehicle of joining of current most of automobile all can be equipped with background light level regulatory function, its operation principle is when after lampet switch open, manual adjustments can comprise the background light level of combination instrument, central display screen and control panel and button everywhere by the dimmer switch being arranged on instrument board lower left side, its drawback is: 1, need manual adjustments.If driver regulates in driving procedure, risk will be caused to drive safety; 2, adjusting condition is after lampet is opened, and lampet not opening time car in backlight there are two kinds of situations: a kind of not light for bias light in car, be another kind ofly illuminated to high-high brightness for bias light in car.If but when travelling suddenly in the environment of different brightness, in car, backlight is crossed dark or crosses and brightly all can cause risk to driving safety.3, general only joining in vehicle at height is equipped with dimmer switch device, and this installation cost is high, cannot use in major part low joining in vehicle.
Summary of the invention
The utility model proposes automatic backlight adjusting device in a kind of car, solve the problem that low background light level of joining combination instrument in vehicle, central display screen and control panel and button everywhere cannot regulate, its structure is simple, reasonable in design, be convenient to realize.
The technical scheme that the utility model adopts is: automatic backlight adjusting device in a kind of car, and its technical essential comprises:
For the low-light level sensor gathered light luminance in car;
For converting pwm signal to the light signal collected, and control according to setting threshold the control unit that background tube drive circuit carries out brightness regulation, described low-light level sensor connection control unit;
For regulating the bias light drive circuit of background light group brightness, described bias light drive circuit connection control unit;
With with the background light group of carrying out throwing light on for in-vehicle device, described background light group connects background tube drive circuit.
As a kind of preferred version of the present utility model, described in-vehicle device comprises combination instrument, central display screen and control panel, each switch key.
As another kind of preferred version of the present utility model, described background light group is changeable colour LED group.
Advantage of the present utility model and beneficial effect: automatic backlight adjusting device in this car, bias light in low-light level sensor connection control unit car is utilized to regulate, without the need to manually, can realize automatically according to the adjustment of light intensity in car to the brightness of bias light by vehicle, this structure does not restrict by lampet on off state, namely no matter lampet whether open all can adjusting backlight luminance automatically, without the need to dimmer switch, greatly reduce development cost; Complete set is all configurable, meets all kinds of consumer group's demand; Without the need to using CAN communication can realize automatic adjustment, make low side low cost vehicle still can meet configuration needs, Promote Competitive.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is automatic backlight adjusting device structural representation in the utility model car;
Fig. 2 is the utility model bias light drive circuit circuit connection diagram.
Embodiment
Below in conjunction with accompanying drawing 1 and Fig. 2, the utility model is further described.
Automatic backlight adjusting device in a kind of car, its technical essential comprises:
For the low-light level sensor 1 gathered light luminance in car.
For converting pwm signal to the light signal collected, and control according to setting threshold (as 5s ~ 10s) control unit 2 that bias light drive circuit carries out brightness regulation, described low-light level sensor 1 connection control unit 2.
For regulating the bias light drive circuit 3 of background light group brightness, bias light drive circuit 3 connection control unit 2.
For the background light group 4 of carrying out throwing light on for in-vehicle device (as in-vehicle device comprises combination instrument, central display screen and control panel, each switch key), background light group connects bias light drive circuit 3, and wherein, background light group is changeable colour LED group.
The bias light drive circuit 3 adopted in the present embodiment, the PWM1 pin of control unit 2 is connected with the PWM pin of bias light drive circuit 3, inductance R170 one end of bias light drive circuit connects one end of electric capacity C111, one end of inductance R169 and the base stage of triode, the other end of electric capacity C111, the other end of inductance R169 are connected and are connected with the emitter of triode, and the collector electrode of triode connects LED group.
The course of work of the utility model device is:
By the low-light level sensor being arranged in vehicle interior, Real-time Collection is carried out to light luminance in car, the monochrome information collected is sent to the control unit of automobile, the control unit of automobile carries out analog-to-digital conversion according to the threshold value of setting to collection signal and becomes pwm signal, pwm signal is sent to by rigid line in the background light group of combination instrument, central display screen and the device such as control panel, each switch key, is automatically adjusted by the brightness of bias light drive circuit to bias light.
Low-light level sensor position is comparatively flexible, the position such as can be arranged in car inside central control panel region or A post.If when dim in car being detected, the signal collected is sent to the control unit of automobile by low-light level sensor, the control unit first-selection of automobile judges the time (as 10s) that light changes, this threshold values is exceeded when the time of light intensity change, then think that change effectively, be converted into the pwm signal of respective strengths by this light intensity signal, then send to bias light drive circuit to weaken to make background light level in car, and brightness change procedure is linearly changed.When Ruo Dangchenei light brightens, then in car, backlight entirety brightens gradually.
Although the foregoing describe embodiment of the present utility model, but the those skilled in the art in this area are to be understood that, these only illustrate, can make various changes or modifications, and do not deviate from principle of the present utility model and essence to these execution modes.Scope of the present utility model is only defined by the appended claims.
