Description
Technical field
The present invention relates to auto meter, relate in particular to a kind of phantom formula automobile combination meter.
Background technology
Auto meter is very big to the driving safety influence of automobile; Automobile driver is grasped automobile single-piece running state in real time through auto meter, and the wrong or automobile driver of auto meter all might cause the automotive safety accident to the false judgment of auto meter display parameter.So the normal operation of auto meter and automobile driver are significant to safe driving to the correct judgement of auto meter.
Existing auto meter mainly is based on the electrical category auto meter of pointer-type; At Chinese patent number is ZL2006201005198; The patent documentation that name is called " a kind of gauge panel that is used on motor bike, the automobile " discloses a kind of analog meter; The instrument of the type comprises dial plate and the pointer that is provided with scale, and the scale value on the pointer dial plate pointed is the pairing value of measured data, and not enough below analog meter exists: an instrument can only show data; Owing to the pointer reason of engineering properties, in the automobile sport process, shaken the perhaps influence in magnetic field, cause the inaccurate fault rate of automobile meter pointer hair fastener or indication higher.
Along with the quick raising of vehicle electronics level, in order to overcome the above problems, the auto meter that the LCD screen shows that passes through of electronic type is applied in the automobile.At Chinese patent mandate publication number is CN201613824U; Name is called and discloses the auto meter that a kind of logical LCD screen shows in the patent documentation of " auto meter display structure "; Instrument in this patent cooperates the pad pasting that is provided with scale to come display data through the LCD screen; An instrument can show two data, has overcome the deficiency of analog meter.
But be passing through the auto meter that LC0 shows and all need adopting the face shield of transparent material that its internal pointer or LCD screen are protected of pointer electrical category auto meter or electronic type; Chaufeur can only see through transparent face shield the data on the instrument are observed; Owing to the reasons such as reflective and refraction of face shield, chaufeur can produce erroneous judgement when instrument is carried out reading.Observe across a face mask simultaneously, observing effect is not good enough.
Summary of the invention
The invention provides a kind of good phantom formula automobile combination meter of observing effect of difficult generation erroneous judgement, solved existing instrument and will read existing can generation erroneous judgement the by accident and the not good enough problem of observing effect through face shield.
Above technical matters solves through following technical proposal: a kind of phantom formula automobile combination meter; Comprise housing; One end of said housing is provided with projection screen, the other end is provided with the projection shaven head that carries out projection towards projection screen; Said projection shaven head is electrically connected signal processor unit; The signal that the electric elements that said signal processor unit is used for that the state to automobile is detected and controls is imported converts the digital quantity viewdata signal into, and said projection shaven head is used for the digital quantity viewdata signal of signal processor unit output with the form flash of image to said projection screen.The imaging surface that is installed in the present invention on the Automobile instrument during use and makes projection screen is towards chaufeur; This moment, projection head was positioned at the rear (rear is the orientation for car body) of projection screen; Vehicle mode control electric elementss such as vehicle state-detection electric elementss such as the car speed sensor on the automobile, tachogen, fuel-quantity transducer and pole changer are connected on the corresponding input end mouth of signal processor unit; Signal processor unit according to the incoming signal of above electric elements convert reaction the vehicle current speed of a motor vehicle, rotating speed into, turn to, the digital quantity view data of states such as travelled distance, oil mass, and through the projection shaven head state of vehicle is projected in the mode of image and supplies chaufeur to watch on the projection screen.
As preferably; Said signal processor unit comprises A/D converter, ECU and the LCD display circuit that is electrically connected; Said projection shaven head comprises light source, light focusing unit, LCD screen and the projection lens that is arranged in order, said LCD screen display image under the effect of said LCD display circuit."
