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 TT introduce

The Audi TT is a sports car developed by Audi, which was first launched in 1998. As a sports sedan, the TT model has achieved great success in the market with its almost identical beautiful appearance and excellent performance to the concept car version. In the early stages of the first generation, some car owners complained about unstable high-speed turning and accidents. Audi adjusted the suspension system of the TT and added a rear spoiler version to the rear of the car, reducing the lift at the rear of the Audi TT from 148 pounds to 53 pounds at a speed of 125 miles per hour, The 64 pound rear lift of the BMW Z3 Coupe and the 68 pound Porsche Boxster, as well as the 104 pound Mercedes SLK, are lower than those of the same period at the same speed. The Audi TT is a pure sports car. There are three models sold in China, namely the TT Coupe 1.8t, TT 2.0TSI, and TT 3.2quattro convertible (soft top). Audi continues to launch a series of completely new cars, from A4.A6 to the current A8 and TT. [2] Audi TT's competitors include BMW X1, Mercedes SLK, etc
