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

corolla introduce

The Corolla is the tenth generation straight upgrade product of Toyota COROLLA. Since its release in November last year, the Corolla has received global consumer attention; Now, this globally popular car has settled in FAW Toyota, once again allowing Chinese consumers to experience Toyota's latest technology and driving experience simultaneously. The predecessor of the Corolla was the AE86! The size of the Corolla body has significantly increased compared to the previous generation Corolla, and the entire vehicle has shown an unprecedented "wide and low" trend, creating a spacious interior space; The newly developed dual VVT-i technology with 1.6-liter and 1.8-liter engines will bring a more powerful power experience in the future The Corolla, the tenth generation Corolla that has been officially released in China and has become the focus of attention at the Beijing and Shanghai Auto Show, is the latest model in its series. It was officially launched on November 16, 2006. The Corolla, which is about to be launched by FAW Toyota, has two displacement models: 1.6L and 1.8L. Whether in terms of appearance, configuration, or power, the Corolla, The Corolla has been greatly improved on the basis of the old Corolla. The average fuel consumption of the Corolla is 8.88L/100km, and car owners have expressed that its fuel consumption is low. According to feedback from car owners in 2012, the Corolla has almost no problem with any malfunctions and its quality is very stable. Car owners generally recognize the Corolla in terms of acceleration and handling, Compared to the old Corolla, there has been a significant improvement. However, the 4-speed automatic transmission is slightly stingy. Car owners generally report that the fastest acceleration is achieved from 2nd to 3rd gear
