Abstract

The invention relates to an automobile instrument, in particular to a phantom-type combined automobile instrument. The phantom-type combined automobile instrument comprises a shell body; a projection screen is arranged at one end of the shell body; a projection light head for projecting towards the projection screen is arranged at the other end of the shell body; the projection light head is electrically connected with a signal processing device; the signal processing device is used for converting signals input by electrical elements, which are used for detecting and controlling the state of an automobile, into digital image data signals; and the projection light head is used for projecting the digital image data signals output by the signal processing device onto the projection screen in the form of an image. The phantom-type combined automobile instrument provided by the invention has the advantages that the misjudgment difficultly occurs, the observation effect is good, and the problems that the misjudgment occurs and the observation effect is not good enough due to the fact that the existing instrument is read through a face shield are solved.

Description

technical field [0001] The invention relates to an automobile instrument, in particular to a phantom automobile combination instrument. Background technique [0002] The car instrument has a great impact on the driving safety of the car. The car driver can grasp the overall running status of the car in real time through the car meter. The error of the car meter or the wrong judgment of the car driver on the display parameters of the car meter may cause car safety accidents. Therefore, the normal operation of the car instrument and the correct judgment of the car driver on the car meter are of great significance to safe driving. [0003] Existing automotive instruments are mainly based on pointer-type electromechanical automotive instruments. A pointer-type instrument is disclosed in the patent document of Chinese Patent No. ZL2006201005198 titled "A Dashboard for Motorcycles and Automobiles". , this type of instrument includes a dial with a scale and a pointer. The scale va...
