Combination instrument assembly introduce

The instrument panel is the interactive interface between humans and cars, providing drivers with the necessary car operating parameters, faults, mileage and other information. It is an essential component of every car. The intuitive and beautiful display of the instrument panel makes driving not only necessary for commuting, but also a part of comfortable life. The accuracy and reliability of parameter transmission are directly related to the safety of car driving [1] The most prominent feature of modern instruments is the modularization of functions. Usually, a single instrument needs to be assembled, and only a few functional modules need to be combined on the basis of customized PCBs to obtain a complete system. The pointer instruments of economic vehicles such as Chang'an are generally independent modules, and the indication/alarm function is completed by small light bulbs on the PCB. The SANTANA series pointer is driven by cross coils on the printed circuit board, The prompt/alarm lights are all the main data displayed on the dashboard of light-emitting diode cars. The source and corresponding display methods. Integrated circuit technology is rapidly developing, and the density and volume of integrated circuits are getting higher and smaller. The internal structure is becoming more complex and the functions are becoming more powerful. As some functions of the instrument panel are constantly replaced by software, hardware is becoming more and more powerful, The integration level of the entire system is also correspondingly improving. This design is based on Freescale microcontrollers and is aimed at traditional cars that dominate the market. It cites Changan's instrument panel as a template, with the main purpose of achieving a low-end solution for automotive electronic instrument panels)

Attention should be paid to the disassembly and assembly of automotive instruments:

Attention should be paid to the disassembly and assembly of automotive instruments: 1. When replacing the meter core or sensor separately, the instrument and sensor must be used together. 2. When disassembling the instrument and sensor, the action should be light and not knocked. 3. The wiring terminals of electromagnetic instruments have polarity and must not be connected incorrectly. The instruments on different car dashboard are not the same, but the conventional instruments in general cars include speedometer, tachometer, oil pressure gauge, water temperature gauge, fuel gauge, charging meter, etc. In modern cars, The automotive instrument panel also needs to be equipped with a voltage regulator, specifically for

Liuzhou Wuling introduce

Liuzhou Wuling Automobile Co., Ltd. (referred to as Wuling Group) was established in 1996 and is a large state-owned sole proprietorship authorized by the Guangxi District Government. Its main business is the production and sales of automotive parts, engines, and specialized vehicles. Wuling Group is one of the top 500 manufacturing enterprises in China, as well as one of the top 500 large industrial enterprises and information technology enterprises in China; In 2002, through asset restructuring and deepening reforms, Wuling Group achieved a tripartite cooperation with SAIC Group and General Motors of the United States, establishing SAIC-GM Wuling Automobile Co., Ltd., which promoted the rapid development of Wuling Automobile during the "15th Five Year Plan" period. The tripartite cooperation transformed one Wuling into two Wulings - two Wulings connected by product ties, property rights ties, and cultural ties
