Abstract
The utility model discloses a backlight system of a button in a forklift cab. A range sensor is arranged beside the button which is provided with a backlight and is arranged in the forklift cab, the range sensor transmits collected signals to a controller, and the controller outputs backlight luminance control signals to a backlight unit. Brightness of the backlight of the button can be enhanced when the backlight of the button is used, the backlight of the button can be slightly bright when the backlight is not used, the user-friendly design for use is achieved, and a driver can carry out control conveniently and accurately.
Description
Technical field
The utility model relates to the backlight system of button in fork truck car.
Background technology
In forklift steering room, touch-controlled key all has backlight, backlight is generally normal bright state, but forklift steering room mostly is open type, external environment is larger on operator's compartment impact, this just causes brightness of backlight sometimes cannot reach demand, affect chaufeur and use, if increase brightness, probably in dark surrounds, affect chaufeur and drive.
Utility model content
The technical problems to be solved in the utility model be realize a kind of can be according to the brightness of backlight that uses status adjustment button.
To achieve these goals, the technical solution adopted in the utility model is: key-press backlight lamp system in forklift steering room, in forklift steering room, there is the other rang sensor that is provided with of button of backlight, described rang sensor is delivered to controller by the signal of collection, and described controller output brightness of backlight controls signal to backlight unit.
The backlight of described backlight unit is LED, and described controller output brightness of backlight control signal is pwm pulse width signal, and is delivered to LED by LED drive circuit.
Described rang sensor is provided with multiple, and each described LED is all furnished with a rang sensor.
The utility model has the advantage of the blast in use of key-press backlight lamp, not used time glimmer, is used hommization, facilitates chaufeur to manipulate accurately.
Accompanying drawing explanation
Mark in content and the figure below each width accompanying drawing of the utility model specification sheets being expressed is briefly described:
Fig. 1 is key-press backlight lamp system block diagram in forklift steering room.
The specific embodiment
Referring to 1 known, in forklift steering room, have that the button of backlight is other is provided with rang sensor 1, rang sensor 1 is delivered to controller 2 by the range signal of collection, and controller 2 controls signal to backlight unit 3 according to range signal output brightness of backlight.
Conventionally in car, each button all has backlight unit 3 separately, and each backlight unit 3 is furnished with respectively rang sensor 1 separately, and chaufeur is being used the bright respective keys of which button time point like this, makes operation more pointed.
After fork truck starts, the LED-backlit lamp of backlight unit 3 is in glimmer state, and when rang sensor 1 outputs signal to controller 2, controller 2 judges that the hand of chaufeur is less than pre-set threshold value apart from button, output control signals to backlight unit 3, now LED-backlit is in the brightest state.
Claims (3)
1. key-press backlight lamp system in forklift steering room, it is characterized in that: the other rang sensor that is provided with of button in forklift steering room with backlight, described rang sensor is delivered to controller by the signal of collection, and described controller output brightness of backlight controls signal to backlight unit.
2. key-press backlight lamp system in forklift steering room according to claim 1, it is characterized in that: the backlight of described backlight unit is LED, described controller output brightness of backlight control signal is pwm pulse width signal, and is delivered to LED by LED drive circuit.
