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

Mercedes-Benz GLE400 introduce

The appearance of the Mercedes Benz GLE400 is very similar to that of the AMG GLE43, with a family style front face, LED daytime running lights, low beams, and high beams. The central grille adopts four hollow chrome decorative strips (similar to the GLE43), and the lower front bumper is also similar to the GLS450 GEL43. The overall line is very smooth, mainly made of chrome decorative materials. The welcome pedals are very Mercedes Benz style, and the five pairs of wheel rims are closer to the design of the AMG GLE43, But the overall effect is more stable without smoky black. In terms of configuration, it supports Android, Apple car play, full-time four-wheel drive, aluminum 20 inch wheels, electric 4-way lumbar support, smartphone connection, Harman sound, automatic air conditioning, ambient lighting, anti-theft alarm, colored heat-insulating glass, electrically folding rearview mirrors, electric sunroof, knee airbags, front side airbags, tire monitoring, blind spot monitoring, distance radar, automatic braking, parking assistance, multiple driving modes, fatigue driving Driving reminder, lane change assistance, 360 surround image, and so on. In terms of power: The 2019 Mercedes Benz GLE400 is equipped with a 3.0T twin turbocharged V6 direct injection gasoline engine, with a maximum horsepower of 333 and a maximum torque of 480 Nm. It is matched with a 9-speed automatic transmission, although not as aggressive as the AMG GLE43, the overall driving experience is full of power
