Car rear cover function
The rear cover of an automobile , commonly known as the trunk cover or the tailgate, its main functions include the following aspects:
Protect the contents of the trunk : The rear cover can effectively block rain, dust and other debris, provide an extra layer of protection for the contents of the trunk, and ensure that the contents are not intruded on .
Reduces drag and optimizes aerodynamics : The robust plastic material for the rear cover ensures durability and safety while also reducing drag and optimizes the vehicle's aerodynamics .
improve the convenience of use : different models of the rear cover design is different, some folding or easy to disassemble, convenient for the owner to load and unload goods. High-end models are even equipped with sensors or motors that switch on and off automatically via buttons or remote controls, greatly improving the ease of use .
In addition, the material and design of the car's rear cover will also affect its function and performance. For example, a lighter but still robust material may be used for the rear cover of some high-end models to further optimise aerodynamics and improve overall vehicle performance .
The working principle of the rear cover of an automobile mainly involves the application of the hydraulic system and the pressure difference . The rear cover, also known as the tailplate, is located at the rear of the vehicle and can be opened and closed. Its working principle mainly includes the following aspects:
Air pressure difference regulation : When the car is driving, the front will move too fast to form a high pressure area in front of the car, and the rear will form a low pressure area. The tailboard controls the tail air passage by adjusting the opening degree, thereby reducing the air pressure difference at the rear of the body and reducing the air resistance .
cargo protection : in the closed state, the tailboard can protect the cargo from external impact and wind and rain, especially in the transport of goods is very important .
air flow optimization : by reasonably adjusting the opening Angle of the tailplate, the air flow at the rear of the vehicle can be smoother, the air resistance can be reduced, and the stability and power performance of the vehicle .
ventilation : Opening the tailgate when parking can increase the ventilation at the rear of the vehicle, which is conducive to interior ventilation and temperature regulation .
Components and modes of operation
The tailboard is mainly composed of closed oil cylinder, panel, bracket, electric control system, hydraulic system and so on. The panel material is usually steel or aluminum alloy, steel panel is durable but heavier, aluminum panel is lighter but higher price. The core components of the hydraulic system include hydraulic pump, hydraulic cylinder, control valve, oil tank and storage battery. When working, the vehicle battery provides power for the DC motor, drives the hydraulic pump to transport hydraulic oil to the hydraulic cylinder, and controls the expansion and expansion of the hydraulic cylinder through the control valve, thus driving the lift of the tailboard platform .
Design differences of different models
The tailgate design varies from car to car. For example, some models have collapsible or easily removable designs to facilitate loading and unloading of items; High-end models may have sensors or motors that switch on and off automatically . These design differences are mainly to improve the ease of use and aerodynamic performance of the vehicle.
