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

BAIC Weiwang 307 introduce

The Weiwang 307 is an extended version of the Weiwang 306, with a length of 4495mm and a wheelbase of 2920mm. As a result, the Weiwang 307 has a larger rear space. The front face of the Weiwang 307 has a more overall feel, and the two mesh grilles make the vehicle more refined and upgraded to a certain extent. The red BAIC logo is also quite festive. It has an additional window on the side that can be opened, which can be used by rear passengers for ventilation and breathability, The interior environment of the Weiwang 307 will become better. Of course, the interior design of the Weiwang 307 is mainly practical, with a simple and simple console design that has obvious Japanese micro car characteristics. The speedometer is a traditional scale, and information such as the tachometer, water temperature gauge, oil gauge, and time are displayed through the digital instrument panel on the right. The Weiwang 307 can be equipped with four rows of seats, and the maximum number of passengers in the car can be increased to 9. If only two rows of seats are selected, So most car owners plan to use this car as a truck. After removing the rear seats, the rear compartment forms a complete loading space. In addition, there are many small storage spaces available on the Weiwang 307, which is very convenient. In terms of power, the Weiwang 307 currently only has a 1.2L four cylinder engine, with a maximum power of 63.5kW and a maximum torque of 108Nm. It is equipped with a 5-speed manual transmission and adopts rear wheel drive. The low-end models do not have steering assistance, making it difficult to turn the wheels in place
