The basics of the car

The car consists of four major parts: engine, chassis, body, and electrical equipment. Car models can be divided into several categories: SUV, MPV, CKD, RV, pickup truck, SKD car, and classic car. According to the characteristics of cars, they can be divided into electric cars, zero-emission cars, hybrid cars, gas cars, and new energy cars. In addition, cars can be divided into 1.3L, 1.6L, 1.8L, 2.0L, 2.4L, 2.5L, 3.0L, etc. according to the engine displacement. Generally speaking, the larger the displacement, the greater the fuel consumption and the more powerful the power output. In addition, the car's onboard voltage is 12 volts.

The body of the car is the foundation for all body parts to be installed. It is generally composed of longitudinal beams, crossbeams, columns, ABC pillars, reinforcement plates of various parts, and other body structures and coverings. Exterior body parts include front and rear bumpers, exterior decorative strips, mirrors, sunroof, door accessories, aerodynamic accessories, etc. Interior parts of the car: the main parts of the car that protect and decorate the driver or occupants, including front and rear seats, dashboard, interior floor, sun visor, interior rear-view mirror, and other visually visible objects.

The new energy vehicles wiring harness, like a meridian that connects various electrical appliances in the body, is important because its arrangement is related to the function and quality of the electrical appliances. In the arrangement of wiring harness, there are usually H, L, E, R types, and other forms of arrangement. In s11, the wiring harness is divided into front compartment wiring harness assembly, engine wiring harness assembly, instrumentation wiring harness assembly, interior wiring harness assembly, door wiring harness assembly (four doors are different), battery negative wiring harness assembly, rear defrost positive wiring harness assembly, rear defrosts negative wiring harness assembly.

The general arrangement of the new energy vehicles wiring harness should be involved in the P2 phase of the complete vehicle. Understand the functional properties and special requirements of the electrical parts of the vehicle (including the location requirements with other parts and the electrical and electronic characteristics) and the assembly process of the vehicle. And based on the above basic data, we can get the high-temperature area, vibration area, and strong electromagnetic interference area of the whole car.

As one of the important parts of the car, the new energy vehicle’s wiring harness is equivalent to the transmission nerve of the car. It has the role of signal control for the car and directly affects the quality and performance of a car. Therefore, in addition to meeting the basic performance requirements of the car, the wiring harness design also requires the high quality of the harness itself. Our company has conducted many tests on the new energy vehicle wiring harness before leaving the factory, and the quality pass rate is guaranteed.
