What is the structure of the instrument in the car?

Automobile dashboard is a device that reflects the running state of each system of the vehicle. Generally, it consists of speedometer, tachometer, oil pressure gauge, water temperature gauge, fuel gauge and electronic indicator light. Automobile instrument is an important interface for exchanging information between driver and automobile. With the development of automobile electronic technology, the information of automobile running state and various mechanisms and parts has greatly increased. When driving a vehicle, the driver should better understand whether various parameters of the car and engine are normal. Measures can be taken in time to prevent accidents.

With the development of electronic technology and the appearance of new sensors and new electronic display elements, automotive electronic equipment has been rapidly adopted. At present, the electronic instrument display devices used in automobiles mainly include light-emitting diodes, vacuum screen displays and liquid crystal displays.

At present, most cars use assembly machines. The instrument cluster usually consists of mask, frame, movement, printed circuit board, connector, warning light, indicator light and other components. Some instruments are equipped with voltage regulators and alarms. The number of instruments on the automobile instrument cluster is different. The main instruments of general instrument panel include fuel gauge, cooling water thermometer, engine tachometer, speedometer, etc. There are many indicator lights, warning lights and instrument lights on the dashboard. From the appearance, the traditional dashboard is mostly digital and touch-sensitive, which is neither beautiful nor stable. The digital instrument panel shows the original ignition position, which makes the focus more vivid, ensures good recognition and is very clear and readable.

From the current overall trend, especially the combination of multimedia technology and personalized centralized screen design style represents the current trend and also represents the design trend. The instrument assembly is mainly composed of circuit board, instrument cover and bottom shell. The main part is the board. An indicator lamp, a controller and a stepping motor are installed on the circuit board. Its core components are single chip microcomputer and stepping motor.
