What material is the lower part of a car trailer cover made of
There are mainly two types of materials for the lower body of a car trailer cover:
Youdaoplaceholder0 plastic material : smooth and lightweight, suitable for daily use, but has relatively weak impact resistance.
Youdaoplaceholder0 metal material : highly durable, suitable for high-intensity operations, but relatively heavy.
The specific materials may vary depending on the model and design. For instance, some models use steel plates or aluminum alloys, and there are also cases where engineering plastics are used. For instance, the original factory parts of the rear bumper traction hook cover of Volkswagen adopt a hard shell design with a matte texture, which has good weather resistance.
The main structure under the cover of a car trailer is usually a trailer hook , which is mainly used for towing vehicles or securing other vehicles in emergency situations. The design of trailer covers varies among different vehicle models, but the core structure is always the hook itself.
Specific structure
Trailer hooks are usually located under the front/rear bumpers and are covered by round or square covers. There are mainly two ways to open it
Youdaoplaceholder0 Press type : It can be opened by pressing the edge of the lid hard for a short time (such as Audi models).
Youdaoplaceholder0 prying type : It can be opened by gently prying along the edge with a tool (applicable to some vehicle models).
Precautions
When towing, make sure the trailer ring is screwed into the limit position to avoid thread breakage and potential safety hazards.
After use, the cover should be reset in time to prevent foreign objects from entering and affecting the structure.
The main functions of the lower body of the car trailer cover (i.e., the trailer hook cover plate) include:
Protection and dust prevention
The trailer hook cover plate is placed at the installation position of the trailer hook, which can prevent external dust, sand and other foreign objects from entering the engine compartment or the interior of the vehicle body, playing a protective role.
Aesthetics and sound insulation
The trailer hook covers of some models are designed in the same color as the body, which not only keeps the vehicle's appearance neat and beautiful but also reduces the noise transmission of the mechanical structure in the engine compartment by shielding.
Ease of installation and disassembly
By designing a reasonable opening method (such as press type, pry type, etc.), it is convenient for users to quickly open the trailer hook cover plate for installation or disassembly operations.
The damage to the lower part of the car trailer cover needs to be handled according to the degree of damage:
Minor damage
If the trailer cover only shows slight deformation or scratches but does not affect the clamping and sealing performance, it can be temporarily not replaced. But it should be noted
Appearance flaws may disrupt the smoothness of the body lines
There may be a risk of water seepage in extreme weather
Severely damaged
The trailer cover must be replaced in a timely manner when the following situations occur:
The inability to close tightly leads to the failure of the seal (water is prone to seepage in heavy rain or waterlogged sections)
When towing, the tow hook cannot be installed normally (affecting the safety and stability of the towing)
Replacement suggestions
Youdaoplaceholder0 Position the tow hook : usually located below the bumper, at the area covered by the round/square cover
Youdaoplaceholder0 opening method :
Gently press around to find a loose Angle
Use a stick wrapped in cloth or a screwdriver to carefully pry (avoid scratching the paint)
Youdaoplaceholder0 Replacement notes :
After replacement, ensure that the cover plate adheres tightly to the vehicle body
Avoid damaging the surrounding paint when operating
Water leakage under the car trailer cover may be caused by the following reasons:
Common causes
Youdaoplaceholder0 air conditioning system drainage
When the air conditioner is running, condensate water will form on the surface of the evaporator and be discharged outside the vehicle through the drain pipe, usually located under the chassis. This situation is a normal phenomenon.
Youdaoplaceholder0 water tank or cooling system failure
If the liquid level in the coolant storage tank is too high or the cooling system pipelines are loose or damaged, it may cause water leakage. It is necessary to check whether there are any bottom scratches or coolant leakage at the bottom of the radiator.
Youdaoplaceholder0 glass water pipe leakage
The trailer cover area may involve the glass water storage tank and pipelines. If the joints are loose or damaged, it may cause leakage.
Youdaoplaceholder0 chassis damage
If the lower part of the trailer cover is scratched, it may damage the glass water pipe or chassis components, which need to be inspected and repaired.
Processing method
Youdaoplaceholder0 check the cooling system
Observe whether the coolant in the water tank is missing and check if the pipelines are loose or damaged.
Youdaoplaceholder0 check the air conditioner drain pipe
Check whether the drain pipe of the evaporator is clogged or fallen off.
Youdaoplaceholder0 inspect the glass water pipeline
Check whether the water storage tank and pipeline joints are loose or damaged.
Youdaoplaceholder0 professional maintenance
If obvious damage or abnormal noise is found in the trailer cover area, a detailed inspection at an auto repair shop is required.
