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

Audi Q7 introduce

The Audi Q7 is a full-size SUV that emphasizes comfort, cleverly integrating sportiness, functionality, high technology, and luxury quality. On the road, it stands out with its infinite dynamic handling and sporty characteristics; On off-road roads, its powerful driving force is even more impressive. Undoubtedly, the Audi Q7 is another groundbreaking masterpiece of the founder of quattro technology at Audi. The Audi Q7 is a luxury sedan produced by Audi, with two modes: racing and station wagon. Its main competitors include the Marseille Mercedes Benz M-Class The BMW X5, Lexus RX, and Volvo XC90. The design and construction of this model are similar to those of the Volkswagen Touareg and Porsche Cayenne series in the same group. The new Audi Q7 has officially been launched in China, representing the Audi brand's entry into the domestic SUV market. The top luxury SUV market is the first to be seized. With its extraordinary charm, the Audi Q7 has also attracted the attention of many consumers in China. Recently, Audi announced that, The Audi Q7, a large SUV, will launch the 2010 new model, which will be equipped with new LED lighting and human-machine interface design
