Abstract
The invention discloses a liquid crystal display stepping motor type combination instrument which comprises a shell body, a lining plate, fault symbol displaying plates and a liquid crystal display screen. The liquid crystal display screen and a barometer are arranged at the center position of the lining plate from top to bottom respectively. The fault symbol displaying plates are arranged on the two sides of the lining plate respectively. A rotating speed meter and an odometer are arranged on the lining plate between the barometer and the fault symbol displaying plates respectively. The rotating speed meter, the odometer and the barometer are driven by a stepping motor. Fault symbols are concentrated on the fault symbol displaying plates and are separated from other pointer meters, faults and pointers can be observed conveniently, and the stability of the pointer meters is guaranteed. The rotating speed meter, the odometer and the barometer are driven by the stepping motor, the parameters such as a solenoid coil, magnetic steel and magnetic force magnitude of the stepping motor are accurate, and accordingly the indicating accuracy of the rotating speed meter, the odometer and the barometer is improved. The fault symbol displaying plates, the rotating speed meter and the odometer are arranged symmetrically, attractiveness is achieved, and observing is convenient.
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
Auto meter is automobile component necessary in auto trade, the auto meter of pointer-type is because of the high widespread use in auto trade of the low stability of cost at present, but on the dial plate of current pointer auto meter, also has fault symbol, fault symbol easily clashes with pointer rotation, reduced like this stability of gauge panel, and be cross line ring type instrument due to what adopt, coil is artificial winding, magnet steel, magnetic force in coil are in different size, cause pointing accuracy not high.
Summary of the invention
Object of the present invention is that well liquid crystal display step motor type combination instrument attractive in appearance again of a kind of pointing accuracy high stability is provided.
To achieve these goals, a kind of liquid crystal display step motor type of the present invention combination instrument, comprise housing, liner plate, fault symbol display panel, LCDs, opening part in described housing front side is provided with liner plate, the upper surface of described housing and lower surface are respectively arranged with two symmetrical instrument mounting holes, center at described liner plate is respectively arranged with LCDs and air-pressure gauge from top to bottom, the both sides of described liner plate are respectively arranged with fault symbol display panel, on the liner plate between described air-pressure gauge and fault symbol display panel, be respectively arranged with speed gage and mileage meter, described speed gage, mileage meter and air-pressure gauge adopt stepping motor to drive, on the trailing flank of described housing, be provided with connector, the inside of described housing is provided with surface-mounted integrated circuit, described fault symbol display panel, LCDs, air-pressure gauge, speed gage, mileage meter is connected with surface-mounted integrated circuit respectively with connector.
As preferably, on described liner plate, be also provided with back to zero bar, on described LCDs, be provided with water thermometer and fuel gage, totally three groups of described connectors, corresponding with the plug on automobile respectively, on described fault symbol display panel, be evenly placed with fault symbol.
Owing to adopting above technical scheme, fault symbol is concentrated on fault symbol display panel, separate with other pointer meters, be convenient to observe fault and pointer, guaranteed again the stability of pointer meters.Speed gage, mileage meter and air-pressure gauge adopt stepping motor to drive, and the parameters such as the magnet coil of stepping motor, magnet steel, magnetic force size are more accurate, and then improved speed gage, mileage meter and barometric pointing accuracy.Fault symbol display panel on liner plate, speed gage, mileage meter are for being symmetrical arranged, not only attractive in appearance, and are convenient to observe.
Accompanying drawing explanation
Now the present invention will be further described by reference to the accompanying drawings.
Fig. 1 is main TV structure schematic diagram of the present invention.
Fig. 2 is backsight structural representation of the present invention.
In figure: 1, fault symbol display panel, 2, speed gage, 3, air-pressure gauge, 4, mileage meter, 5, LCDs, 6, instrument mounting hole, 7, liner plate, 8, back to zero bar, 9, connector, 10, housing.
The specific embodiment
As Fig. 1, shown in 2, a kind of liquid crystal display step motor type of the present invention combination instrument, comprise housing 10, liner plate 7, fault symbol display panel 1, LCDs 5, opening part in housing 10 front sides is provided with liner plate 7, the upper surface of housing 10 and lower surface are respectively arranged with two symmetrical instrument mounting holes 6, in the center of liner plate 7, be respectively arranged with from top to bottom LCDs 5 and air-pressure gauge 3, the both sides of liner plate 7 are respectively arranged with fault symbol display panel 1, on the liner plate 7 between air-pressure gauge 3 and fault symbol display panel 1, be respectively arranged with speed gage 2 and mileage meter 4, speed gage 2, mileage meter 4 and air-pressure gauge 3 adopt stepping motor to drive, on the trailing flank of housing 10, be provided with connector 9, the inside of housing 10 is provided with surface-mounted integrated circuit, fault symbol display panel 1, LCDs 5, air-pressure gauge 3, speed gage 2, mileage meter 4 is connected with surface-mounted integrated circuit respectively with connector 9.On liner plate 7, be also provided with back to zero bar 8, on LCDs 5, be provided with water thermometer and fuel gage, totally three groups of connectors 9, corresponding with the plug on automobile respectively, on fault symbol display panel 1, be evenly placed with fault symbol.
Surface-mounted integrated circuit sets program in advance, by connector 9, be connected with the plug on automobile, switch on power, and the information such as the rotating speed of automobile, mileage, fault, tire pressure are passed to surface-mounted integrated circuit, according to information surface-mounted integrated circuit, control speed gage 2, mileage meter 4, air-pressure gauge 3 and fault symbol display panel 1 and make corresponding demonstration.
Fault symbol is concentrated on fault symbol display panel 1, separate with other pointer meters, be convenient to observe fault and pointer, guaranteed again the stability of pointer meters.Speed gage 2, mileage meter 4 and air-pressure gauge 3 adopt stepping motor to drive, and the parameters such as the magnet coil of stepping motor, magnet steel, magnetic force size are more accurate, and then improved the pointing accuracy of speed gage 2, mileage meter 4 and air-pressure gauge 3.Fault symbol display panel 1 on liner plate 7, speed gage 2, mileage meter 4 are for being symmetrical arranged, not only attractive in appearance, and are convenient to observe.
