Abstract
The invention discloses a four-stepping-motor combination instrument of a light truck. The four-stepping-motor combination instrument of the light truck comprises a shell, a lining plate, a fault symbol display panel, an odometer, a revolution meter, a water temperature gauge and a fuel gauge. The odometer and the revolution meter are located on the portions, located on the two sides of the fault symbol display panel, of the lining plate. The water temperature gauge with a pointer and the fuel gauge with a pointer are located below the odometer and the revolution meter respectively. The fault symbol display panel, the odometer, the revolution meter, the water temperature gauge and the fuel gauge are connected with an integrated circuit board. Pointers of the odometer, the revolution meter, the water temperature gauge and the fuel gauge are driven by stepping motors. Through driving of the stepping motors, the high anti-jamming capability is achieved, the stability of the odometer, the stability of the revolution meter, the stability of the water temperature gauge and the stability of the fuel gauge are guaranteed, indication is safer and more reliable, the parameters, such as electromagnetic coils, magnetic steel and magnetic force, of the stepping motors are more accurate, revolution of the stepping motors is more accurate, and then the indication precision of the odometer, the revolution meter, the water temperature gauge and the fuel gauge is improved.
Description
Technical field
The present invention relates to a kind of auto meter, is a kind of band liquid crystal display and stepper motor driven combination instrument specifically.
Background technology
Light card automobile is in the important effect of carrier performance person; therefore for the instrument on light card automobile, need to possess good antidetonation antijamming capability; but at present for the instrument on light card automobile; the part that its core is rotated adopts convenient type crossed coil; magnet steel, magnetic force in this coil are in different size; cause pointing accuracy not high; and this coil does not have shell protection; very easily being subject to external magnetic field disturbs; finally cause indicating malfunctioning; for speed indication, easily judge by accident especially, have very large potential safety hazard.
Summary of the invention
Object of the present invention is to provide the light card automobile that a kind of antijamming capability is strong, pointing accuracy is high, durable four stepping motor combination instrument.
To achieve these goals, light card automobile four stepping motor combination instrument of the present invention, comprise housing, liner plate, fault symbol display panel, mileage meter, speed gage, water thermometer and fuel gage, the upper surface of described housing and the front side of lower surface are respectively arranged with two pairs of symmetrical instrument hangers are installed, on the sidewall at described housing rear, be provided with connector, the opening part of described housing front side is connected with liner plate, and be provided with surface-mounted integrated circuit in enclosure interior, described fault symbol display panel is positioned at the midway location of liner plate, described mileage meter and speed gage lay respectively on the liner plate of fault symbol display panel both sides, below the dial plate of mileage meter and speed gage, be respectively arranged with water thermometer and fuel gage with pointer, described fault symbol display panel, mileage meter, speed gage, water thermometer is connected with surface-mounted integrated circuit respectively with fuel gage.
As preferably, above described liner plate, be also provided with turning indicator, the pointer of described mileage meter, speed gage, water thermometer and fuel gage drives by stepping motor.
Owing to adopting above technical scheme, the pointer of mileage meter, speed gage, water thermometer and fuel gage drives by stepping motor, stepping motor drives not only has antijamming capability well, guaranteed the stability of mileage meter, speed gage, water thermometer and fuel gage, make to indicate safety and reliability, and the parameter such as magnet coil of stepping motor, magnet steel, magnetic force size is more accurate, make the rotation of stepping motor also more accurate, and then mileage meter, speed gage, water thermometer and fuel gage pointing accuracy have been improved.
Accompanying drawing explanation
Now the present invention will be further described by reference to the accompanying drawings.
