Problems solved by technology

This kind of instrument panel is used in the state of severe mechanical vibration generated when the motor vehicle is running, the work is unreliable, unstable, short life, narrow indication, backward technology, complicated manufacturing process, many process equipment, low display accuracy; and the above-mentioned style The layout of the instrument panel is scattered and difficult to observe. The driver must pay attention to each indicating instrument at any time to know whether a certain parameter is out of the normal range. Moreover, the existing instrument panel with liquid crystal display uses a single pointer display, which is not compact enough and takes up more space. Big

Abstract

This invention relates to a kind of auto car electronic instrument tray, its display unit scope face is Liquid Crystal Display (LCD). The LCD engine speed display instrument and vehicle velocity display instrument are one and the same indicating head, respectively by LCD hand to point each numerical value. The described two hand length are difference, the long pointer include luminous short pointer and luminous stretch;this invention possess ability of show auto car velocity, aggregate mileage, engine speed, water temperature, fuel remainder, oil pressure, Working Voltage, direction signal light and so on reliable, visually and exactly, and possess feature of noticing water temperature, oil pressure, fuel hold-up, vehicle velocity.

Description

Technical field [0001] The invention relates to an instrument panel of a motor vehicle. Background technique [0002] At present, the instrument panel used on motor vehicles generally adopts mechanical, magnetic induction, and electric heating, and uses pointers to display vehicle speed, mileage, fuel, water temperature, oil pressure, and voltage. This kind of instrument panel is used in the severe mechanical vibration state generated by the driving of a motor vehicle, and the work is unreliable, unstable, short life, narrow indication, backward technology, complicated manufacturing process, many process equipment, low display accuracy; and the above-mentioned styles The layout of the instrument panel is scattered and difficult to observe. The driver must pay attention to the indicators at any time to know whether a parameter is out of the normal range, and the existing instrument panels with LCD display use single pointer display, which is not compact enough and takes up more sp...
