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

Buick Excelle XT introduce

The Buick Excelle XT is more fashionable and sporty, with a focus on home use. The Buick Excelle XT's stylish two box sporty appearance is loved by many young people, while the Buick Excelle GT is a three box car that leans more towards home use from the inside out and is no longer as flamboyant. It can be said that the launch of the Excelle GT has expanded the audience of the Excelle series trains. The overall design of the Excelle GT three box car is more oriented towards home use, with a more stable appearance compared to two boxes. From the perspective of appearance, The GT tends to be the popular mid size Buick LaCrosse, also known as the "Little LaCrosse". The Excelle XT is generally more sporty, and from the front face, there is a certain difference between the two cars. The front of the Excelle GT is more rounded and thick, while the Excelle XT has a "steel cannon temperament", full of fashion and sportiness. The headlight design of the Excelle GT is more regular than that of the XT, and the eyes are not as sharp as the XT. The bright and lively upward sloping headlights integrate the width indicator lights, low beam lights, high beam lights, and corner turning lights, The large three shield emblem is embedded on the wide waterfall style air intake grille. The Yinglang GT has two additional gill shaped heat sinks on the engine compartment cover, adding some embellishments to the engine compartment cover. The Yinglang GT has a smooth side shape, which is very in line with people's aesthetic of family cars. After adding one more compartment, the body proportions are still coordinated The shape of the triangular window on the C-pillar has slightly changed compared to the XT. Compared to the Excelle hatchback XT, the roof of the Excelle GT is more protruding, so the rear headroom will be more comfortable
