Description
Technical field
The utility model relates to a kind of vehicle instrument or instrument boards, and in particular to a kind of liquid crystal with mechanical indicating pointer
Instrument board.
Background technique
There are two types of states for existing automobile instrument panel product, and one is full liquid crystal instruments not to have mechanical indicator, passes through liquid crystal display
Show virtual mouse, but the sense of reality of entity pointer is not achieved in the variation of the light sensation of virtual mouse.And the automobile after looking forward to the prospect several years
The development of instrument, future all should be full liquid crystal instrument.But following two are encountered when producing full liquid crystal instrument at present and is asked
Topic:
1, full liquid crystal instrument cost is too high, and cost is conventional combination instrument more than 2 times；
2, the instrument of all inadaptable not mechanical indicator of main engine plants and user, user when using full liquid crystal instrument still
So want the effect with mechanical indicator, can more intuitively observe the variation of revolving speed and speed in this way.
Utility model content
It is false without mechanical indicator or pointer light sensation that the purpose of this utility model is to overcome existing full LCD screens
Problem has supplied a kind of mechanical pointer liquid crystal instrument disk.
The mechanical pointer liquid crystal instrument disk of the utility model, including liquid crystal instrument disk ontology, further include mechanical indicator and
Pointer rotating electric machine；
Mechanical indicator is located at the front of liquid crystal display in liquid crystal instrument disk ontology, and pointer rotating electric machine is located at liquid crystal display
The power output shaft at the rear of screen, pointer rotating electric machine is connected with mechanical indicator, for driving mechanical indicator in liquid crystal display
Place plane internal rotation；
The driving signal output end of automobile controller in automobile and the driving signal input of pointer rotating electric machine are electrical
Connection.
The beneficial effects of the utility model are: providing the liquid crystal instrument dish structure with mechanical pointer, which is
Using the segment code type liquid crystal display of full wafer, aperture is opened up in the pointer position of liquid crystal display, allows liquid crystal display and machinery
Pointer is perfectly combined togather, so that driver's most can intuitively experience speed and rotation speed change.
Detailed description of the invention
Fig. 1 is the disassemblying structure schematic diagram of the mechanical pointer liquid crystal instrument disk of the utility model；
Fig. 2 is the electrical module structural schematic diagram of the mechanical pointer liquid crystal instrument disk of the utility model；
