Abstract
The invention discloses a gun barrel type stepping motor combination instrument which comprises a shell, a panel, a lining plate, a fault symbol display plate, a liquid crystal display screen and a gun barrel type dial plate. The panel is connected to the position of an opening in the front side of the shell, a connector is arranged on the lateral wall of the rear portion of the shell, an integrated circuit board is arranged in the shell, two groups of symmetrical instrument installation holes are formed in the left side of the panel and the right side of the panel respectively, the gun barrel type dial plate comprises a gun barrel type revolution meter and a gun barrel type odometer, and the fault symbol display plate, the liquid crystal display screen, the gun barrel type revolution meter and the gun barrel type odometer are connected with the integrated circuit board respectively. A pointer of the gun barrel type revolution meter and a pointer of the gun barrel type odometer are driven by a stepping motor, the parameters such as solenoid coils, magnetic steel and magnetic force magnitude of the stepping motor are accurate so that the stepping motor can drive the pointers to rotate more accurately, and therefore the indicating accuracy of the gun barrel type revolution meter and the indicating accuracy of the gun barrel type odometer are improved.
Description
Technical field
The present invention relates to a kind of auto meter, is a kind of barrel type stepping motor combination instrument specifically.
Background technology
Auto meter is automobile component conventional in auto trade, auto meter is of a great variety at present, barrel type instrument is used widely in auto trade because dial plate is elegant in appearance, but what the coil of barrel type instrument adopted at present is convenient type crossed coil, this 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 barrel type stepping motor attractive in appearance combination instrument again of a kind of pointing accuracy high stability is provided.
To achieve these goals, barrel type stepping motor combination instrument of the present invention, comprise housing, panel, liner plate, fault symbol display panel, LCDs and barrel type dial plate, opening part in described housing front side is connected with panel, on the sidewall of described housing rear, be provided with connector, described enclosure interior is provided with surface-mounted integrated circuit, be respectively arranged with the instrument mounting hole of two groups of symmetries in the left and right sides of described panel, described barrel type dial plate comprises barrel type speed gage and barrel type mileage meter, described fault symbol display panel, LCDs, barrel type speed gage is connected with surface-mounted integrated circuit respectively with barrel type mileage meter.
As preferably, described panel is arranged on the outward flange of shell nozzle by the bayonet socket on housing.
As preferably, described LCDs is positioned at the middle part of panel, and described fault symbol display panel is positioned on the panel of LCDs top.
As preferably, described barrel type speed gage and barrel type mileage meter lay respectively on the panel of the LCDs left and right sides, in the outer side tube-wall of described barrel type speed gage and barrel type mileage meter, be provided with liner plate, and the pointer of barrel type speed gage and barrel type mileage meter drives by stepping motor.
As preferably, on described panel, be also provided with back to zero bar.
Owing to adopting above technical scheme, the pointer of barrel type speed gage and barrel type mileage meter adopts stepping motor to drive, the parameters such as the magnet coil of stepping motor, magnet steel, magnetic force size are accurate, make stepping motor drive the more accurate of pointer rotation, and then improved the pointing accuracy of barrel type speed gage and barrel type mileage meter.Fault symbol concentrates on fault symbol display panel, separates with other pointer meters, is convenient to attractive in appearance being convenient to and observes, and has improved again the stability of pointer meters.
