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

The LaCrosse is a brand new mid to high end sedan launched by Shanghai General Motors on February 22, 2006. Its positioning is between the Regal and the Roewe, with main competitors such as the Teana and Accord. Shanghai General Motors launched the LaCrosse in order to replace the Regal and occupy an important position in the domestic mid to high end car market. The Buick LaCROSSE LaCrosse, a globally synchronized advanced platform of General Motors, combines domestic and foreign advantageous resources with independent research and development, Bringing cutting-edge technology, leading power, and first-class safety technology, we create a thrilling driving experience for you. Our luxurious equipment and exquisite craftsmanship provide a comfortable and luxurious ultimate riding experience. The LaCrosse is a pure American car, with its American prototype being the Buick LaCrosse. This car is a model that replaces the Century and Regal in the United States The LaCrosse, Pontiac GrandPrix, Chevrolet Antelope, and Monte Carlo share a chassis on the W platform. During the design process, General Motors did not put too much effort or manpower into it. Because in North America, its niche market has already been occupied by Chrysler's 300C and other Japanese cars, The purpose of General Motors launching the LaCrosse is to meet the needs of traditional American consumers who prefer "spacious cabins, comfortable driving, affordable prices, and an American brand." Shanghai General Motors brought the LaCrosse to China and renamed it the LaCrosse after making changes in the Pan Asian Center, entering the Chinese market as a mid to high end car
