What is the trunk lid of a car?
The car luggage compartment lid, also known as the trunk lid or tailgate, is a removable cover installed at the rear of the vehicle, mainly used to cover and protect the storage space of the trunk.
Basic Definition and Function:
It is a separate body assembly, usually made of materials such as steel plates, aluminum alloys, or plastics, which serves to waterproof, dust-proof, and sound-proof, ensuring the safety and dryness of the items inside the vehicle.
In an accident, the luggage compartment lid can sometimes be used as an escape route.
Some models also integrate safety features such as emergency switches for the fuel tank lid.
Structure and Design:
Structurally, it is welded together by an outer panel and an inner panel. The inner panel is often designed with reinforcing ribs to enhance rigidity and has a smooth surface to meet aesthetic and painting requirements.
Some models adopt a "two-and-a-half-box" design, incorporating the rear windshield within the luggage compartment lid, forming a larger rear door structure, which is convenient for storing and retrieving items.
The opening methods include manual, electric, and intelligent sensing (such as automatic opening through sensors), and the supporting components commonly use air springs or hinges to make the opening and closing more effortless and smooth.
Related Components and Classification:
The luggage compartment lid is one of the 13 external structural surfaces of a car, and its design must comply with national standards (such as GB15741-1995).
It is important to distinguish between "luggage compartment lid" (the external removable cover) and "trunk lid panel" (the internal decorative panel used for heat insulation and soundproofing), the latter is located above the trunk. In conclusion, the luggage compartment lid is an important automotive component that combines practicality, safety, and aesthetic design.
The car trunk lid (also known as the trunk cover or tailgate) is a crucial opening component at the rear of the vehicle. Its functions go beyond just being a "lid", and are mainly reflected in the following aspects:
Provide storage space: As the entrance to the vehicle's trunk, the trunk lid provides passengers with space to store luggage, shopping bags, sports equipment, tools, and other spare items, significantly enhancing the practicality and convenience of the vehicle.
Protect items inside the vehicle and the safety of occupants: In the event of a collision or sudden braking, the trunk lid can effectively prevent items in the trunk from flying forward due to inertia, reducing potential harm to passengers in the rear seats and serving as a safety barrier. Some models also use its structural design as an emergency escape route in accidents.
Sealing and protection: The trunk lid is equipped with sealing strips, which can effectively prevent rain, dust, noise, and odors from entering the trunk and the vehicle interior, keeping the interior dry and clean, and reducing wind noise during driving, thereby improving the comfort of the ride.
Integrated auxiliary functions: Some trunk lids are equipped with emergency switches for the fuel tank cover, antennas, reverse radars, or cameras.
High-end models may also be equipped with electric tailgates, intelligent sensor opening (such as foot-kick sensing), and other convenient functions.
Aesthetics and aerodynamics: The trunk lid is one of the 13 key exterior surfaces of the vehicle. Its shape is highly unified with the overall design language of the vehicle, directly influencing the appearance aesthetics and aerodynamic performance of the vehicle.
In addition, it should be noted that the trunk partition (or cover curtain, cover plate) is an independent accessory located inside the trunk, below the trunk lid, mainly used to cover items, prevent dust, divide areas, and enhance privacy. It is a separate component from the trunk lid itself.
