A kind of automobile instrument
Technical field
The utility model relates to a kind of instrument, specifically is a kind of automobile instrument.
Background technology
At present, automobile mostly is to adopt moving magnet to drive pointer with conventional instrument, and pointing accuracy is low, and phenomenons such as pointer blocks, pointer shake also take place easily, and conventional instrument shows that to adopt the transmission bulb to be unfavorable for energy-conservation in addition, and displaying contents is limited.
The utility model content
In order to overcome the shortcoming that above-mentioned prior art exists, the purpose of this utility model is to provide a kind of automobile instrument, and its pointing accuracy height is energy-conservation.
For addressing the above problem, the technical solution of the utility model is: this automobile comprises housing with instrument, is arranged on speed of a motor vehicle dial plate, rotating speed dial plate, air pressure dial plate, fuel oil dial plate, cooling-liquid temperature dial plate in the housing and the pointer that cooperates with each dial plate; Described each pointer is installed in respectively on the output shaft of a stepping motor; Also comprise the Programmable Logic Controller of each stepping motor action of control, Programmable Logic Controller is provided with the CAN interface with the CAN bus communication.
As further technical scheme of the present utility model:
, also comprise being used for fixing the LCDs that shows mileage, time, date, gear and roll display literal alarm message with in the instrument at this automobile, also comprise LED bell character (BEL) signal lamp.
With in the instrument, speed of a motor vehicle dial plate maximum range is 140km/h at this automobile, and minimum calibration is 5km/h.
With in the instrument, the maximum range of rotating speed dial plate is 3500r/m at this automobile, and minimum calibration is 100r/m.
With in the instrument, the maximum range of air pressure dial plate is 1500kpa at this automobile, and minimum calibration is 500kpa.
The beneficial effects of the utility model are: it adopts stepper motor drive finger pointing accuracy height, the LED warning indicator lamp is energy-conservation, in addition its LCDs can be intelligent, Hanzify display control program directly perceived and instrument content, caution content, I/O information; The producer, user can directly learn the fault content in automobile control, the electric system from instrument shows, warns.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described further:
Fig. 1 is a structural representation of the present utility model,
Fig. 2 is a birds-eye view of the present utility model,
Among the figure: 1 housing, 2 speed of a motor vehicle dial plates, 3 rotating speed dial plates, 4 pointers, 5 stepping motors, 6 LCDs, 7 LED bell character (BEL) signal lamps.
The specific embodiment
As shown in Figure 1 and Figure 2, this automobile comprises housing 1 with instrument, is arranged on speed of a motor vehicle dial plate 2, rotating speed dial plate 3, air pressure dial plate, fuel oil dial plate, cooling-liquid temperature dial plate in the housing 1 and the pointer 4 that cooperates with each dial plate.Speed of a motor vehicle dial plate maximum range is 140km/h, and minimum calibration is 5km/h.The maximum range of rotating speed dial plate is 3500r/m, and minimum calibration is 100r/m.The maximum range of air pressure dial plate is 1500kpa, and minimum calibration is 500kpa.
As shown in Figure 1, each pointer 4 is installed in respectively on the output shaft of a stepping motor 5.This automobile also comprises the Programmable Logic Controller that each stepping motor of control moves with instrument, and Programmable Logic Controller is provided with the CAN interface with the CAN bus communication.Vehicle speed signal, tach signal, air pressure signal, fuel oil signal, cooling-liquid temperature signal by the CAN bus transfer to this automobile with the Programmable Logic Controller in instrument, Programmable Logic Controller drives each stepping motor action again, makes each pointer rotate the concrete numerical value of indication.Stepping motor can increase
This automobile is provided with the LCDs 6 that is used for fixing information such as showing mileage, time, date, gear and roll display literal alarm message with instrument, also comprises LED bell character (BEL) signal lamp 7.When reporting to the police, the flicker of LED bell character (BEL) signal lamp, roll display literal alarm message on the while LCDs is as " right steering lamp et out of order " ...Adopt LED energy-conservation, and be difficult for heating, can prolong the long service life of instrument.
