The function of a suitcase lid
The main functions of a car trunk lid include protecting items inside the vehicle, enhancing safety, reducing noise and sound insulation, and optimizing space management.
Protective function
The trunk lid effectively isolates the trunk from the interior space through its functions of heat insulation, sound insulation and odor isolation, preventing dust, liquids or odors from entering. Meanwhile, in the event of sudden braking or collision, it can prevent objects from splashing and reduce the risk of secondary injury to the occupants.
Safety
The trunk LIDS of some car models are equipped with a function to prevent accidental opening, which can reduce the risk of items falling or being stolen. The high-strength material and structure can withstand certain impact forces, ensuring the safety of the items in the trunk.
Space management
Supports a layered storage design, allowing different items to be stored in separate areas through partitions (such as light items on the upper layer and heavy items on the lower layer), thereby enhancing the utilization rate of the trunk. Some models also offer foldable and detachable partitions for easy transportation of large items.
Comfort
Thickened sound insulation materials can reduce abnormal noises from object collisions and maintain a quiet environment inside the vehicle. The trunk LIDS of some models also feature anti-slip textures to prevent items from sliding or shifting.
There are mainly the following common types of materials for suitcase LIDS:
PC material
Made of Covestro PC material (commonly known as "soft steel plate"), it features high compressive strength and shock resistance. It is often used in box structures, and the covers of some models may also be made of this material. Abs +PC composite materials are also often used for box covers, featuring both toughness and hardware. .
PP material
Some 20-inch suitcases are made of eco-friendly PP material, which is characterized by its wear resistance and pressure resistance, making them suitable for short-term use or light needs.
Aluminum alloy
A few high-end models are made of aluminum alloy, which has the advantages of high strength and lightweight. For example, the trunk lid of the Audi Q3 is made of aluminum alloy.
Precautions
Aluminum-framed suitcases are usually made of metal, but they are relatively heavy and prone to deformation. The zipper type is lighter but less supportive.
The malfunction of a car trunk lid can be caused by various reasons. Common problems include inability to close, inability to open or abnormal noises, etc. It is necessary to investigate and solve the problem based on the specific manifestations.
Common reasons why it cannot be closed
Youdaoplaceholder0 Foreign objects blocking : Improper placement of items in the suitcase or having foreign objects (such as stones, leaves) stuck at the edges hindering the closure.
Youdaoplaceholder0 Lock buckle failure : Long-term use leads to deformation of the lock tongue, wear of the lock core, or blockage of the lock buckle gap by foreign objects.
Youdaoplaceholder0 Loose/damaged hinge : The hinge screws are loose, rusty or deformed, causing the box cover to shift and fail to fit.
Youdaoplaceholder0 Aging of sealing gasket : The hardening or deformation of the gasket affects the sealing performance and a new gasket needs to be replaced.
Common reasons for failure to open
Youdaoplaceholder0 Hydraulic rod failure : Weakened assist function makes opening difficult. Check the hydraulic oil level or replace the hydraulic rod.
Youdaoplaceholder0 connecting rod breakage : Frequent use of the key to open may cause the connecting rod to break due to fatigue, and professional maintenance is required.
Youdaoplaceholder0 Remote key issue : Insufficient battery power or signal failure. You can try replacing the battery or unlocking manually.
Other possible reasons
Youdaoplaceholder0 sensor failure : Detection misjudged not fully closed, triggering the protection mechanism.
Youdaoplaceholder0 Low-temperature effect : Ice formation in winter leads to an increase in weight or a decrease in spring pressure. It is necessary to clear the ice and adjust the spring.
Youdaoplaceholder0 suggestions for handling :
Give priority to checking for simple issues such as foreign objects, locks and hinges;
If there are faults involving hydraulic rods, connecting rods or sensors, it is recommended to have them inspected and repaired at a professional repair shop.
Regular cleaning of the lock and lubrication of the hinges can prevent malfunctions from occurring.
