What is the trunk lid of a car
Trunk lid is an openable cover installed at the rear of a vehicle and is often referred to as the trunk lid, trunk lid, or tailgate. Its main function is to cover and protect the trunk storage space, to prevent rain, dust, etc. from entering, while providing a beautiful appearance .
The materials of trunk LIDS are diverse, with common ones including steel plates, aluminum alloys, plastics and composite materials. Steel plate material is strong and durable, aluminum alloy material has the advantage of light weight, while plastic and composite material are easy to form, can meet the design requirements of different models .
Trunk lid design combines aesthetics and aerodynamics, and with the development of the automotive industry, its opening methods have also been constantly improving, from manual to electric, sensor opening, etc, becoming more and more convenient .
For example, the electric tailgate function can be activated by button, remote key or foot-sensing, etc., greatly enhancing convenience .
In daily use, maintenance of the trunk lid is also very important, including regular checks of its airtightness, air support, hinge and lock function, and keeping the surface clean .
In addition, with the development of technology, the application of smart technologies has made the trunk lid even more intelligent, such as the sensor opening function, which opens automatically when the owner brings the key close to .
The material of trunk covers varies by vehicle model and manufacturer. Common materials include plastic, fiberglass reinforced plastic composite, aluminum alloy, steel . The specific material depends on the vehicle positioning, cost considerations and the manufacturer's choice.
Youdaoplaceholder0 Common trunk cover plate materials and features
Youdaoplaceholder0 PLASTIC .
It is mainly used in economy models, being lightweight and low-cost, but with relatively weak durability and protective performance.
Youdaoplaceholder0 Fiberglass reinforced plastic composites .
Commonly found in mid-to-high-end models, it features lightweight, high strength and corrosion resistance, making it suitable for vehicles with high performance requirements.
Youdaoplaceholder0 Aluminium alloy .
It is mostly used in luxury or sports models. Its advantages include corrosion resistance and light weight, but the cost is relatively high (for example, some models of Corolla use aluminum covers).
Youdaoplaceholder0 Steel plate .
It is renowned for its high strength and anti-rust performance, and is often used in safety-focused models (such as some versions of the Focus).

Youdaoplaceholder0 How to determine the material of a particular model
Consult the official specification manual of the vehicle or the manufacturer's instructions.
Physical tests (such as magnetic attraction method) can be used to assist in judgment, but it should be noted that non-ferrous metals such as aluminum alloy may also not be magnetized.
Youdaoplaceholder0 Influencing factors of material selection
Youdaoplaceholder0 Vehicle positioning : Economy cars tend to be plastic, while luxury cars tend to be aluminium or composite.
Youdaoplaceholder0 Performance requirements : Fiberglass reinforced plastic and aluminum alloy are more suitable for vehicles that pursue lightweight and strength.
Youdaoplaceholder0 The main causes and solutions of car trunk cover plate failure mainly include the following situations:
Youdaoplaceholder0 Linkage rod or lock core problem : If you frequently use the key to open the trunk lid, the linkage rod may be broken; If you keep using the remote control, it might be that the lock core is dirty or rusty. The solution is to have the lock core inspected and repaired at a 4S store or repair shop.

Youdaoplaceholder0 Body parts failure : There is a problem with the trunk itself, such as a broken wiring harness or other mechanical parts failure. The solution is to go to a repair shop or 4S store to check and repair or replace the faulty part .
Youdaoplaceholder0 Seal sticking : In several BMW models, the trunk lid cannot be fully opened, mainly due to seal sticking. The solution is to clean the contact area of the seal and lubricate it with the specified lubricant .
Youdaoplaceholder0 Lock block fault : If the trunk can be unlocked normally but not opened, it may be a lock block fault. The solution is to check the lock block, replace the lock block assembly if necessary, or use a mechanical key to open the trunk .
Youdaoplaceholder0 Linkage spring failure : If the rear tailgate can be unlocked normally but does not spring up, it may be a linkage spring failure. The solution is to check whether the spring is stuck or deformed and fallen off. If necessary, carry out lubrication treatment.
Youdaoplaceholder0 Wiring problem : In some models, the center console control auto-unlock function may fail to operate the trunk properly due to a wiring fault. The solution is to check and fix the line problem .
