The function of the side skirt of a car
The side skirts of a car (commonly known as side skirts) mainly have the following functions:
Optimize aerodynamics
Side skirts reduce the airflow from both sides of the vehicle entering the underside, lowering air resistance and enhancing the stability of the vehicle during high-speed driving. Its design can guide the orderly flow of air, reduce reverse air flow and lower fuel consumption.
Protect the car doors and bottom components
When parking daily, the side skirts can prevent the car doors from coming into direct contact with obstacles such as curb stones, reducing the risk of damage to the car doors. Meanwhile, in the event of a collision accident, it can disperse the impact force and protect the outer components of the main beam such as the fuel tank and the drying tank.
Enhance vehicle safety
Some side skirts have anti-collision functions. In side collisions, they can absorb energy, reduce the degree of vehicle damage, and provide additional protection for the occupants inside the vehicle.
Decorate the body lines
As part of the body spoiler kit, side skirts can refine the body lines, enhancing the overall smoothness and dynamic visual effect.
The side lower skirt (side skirt) of a car is a skirt plate structure installed on both sides of the vehicle body and located below the car door. It is an important component of the vehicle body spoiler kit.
Core function
Youdaoplaceholder0 Aerodynamic optimization
By suppressing the airflow on both sides of the vehicle body from entering the underside of the vehicle, air resistance can be reduced, and the wind resistance can be lowered by 5% to 7% during high-speed driving.
Youdaoplaceholder0 enhance driving stability
A reasonable design can improve the airflow direction under the vehicle, reduce the lift effect, enhance the grip performance, and ensure driving safety.
Youdaoplaceholder0 protects the vehicle body
It can prevent foreign objects such as sand and stones from scraping and damaging the bottom edge of the car door, and also has a protective function.
Materials and Structures
Youdaoplaceholder0 entry-level models : They mostly use high-strength plastic/resin composite materials (such as PP+GF30), which balance lightweight and scratch cushioning.
Youdaoplaceholder0 Performance models : Some are made of carbon fiber or aluminum alloy to enhance torsional rigidity and body rigidity.
Practical functions
Integrated drainage holes (for some models)
High-end models are equipped with built-in wiring harness channels to optimize the chassis layout.
The treatment method for faults of car side lower skirts (side skirts) should be selected based on the degree of damage and material:
Common causes
Collisions and scratches are the main causes, especially when meeting or stopping on narrow roads, it is easy to come into contact with obstacles, leading to local damage. Material aging, quality issues or improper installation can also cause malfunctions.
Minor injury treatment
Youdaoplaceholder0 plastic material : It can be restored to its shape by gently tapping with a small hammer wrapped in a towel, or by pouring hot water to expand and repair the dent.
Youdaoplaceholder0 Metal material : Surface rust can be sanded with sandpaper and then repainted. Dents can be repaired with suction cups or sheet metal.
Severe damage treatment
In case of large-scale cracking, deformation or detachment, it is recommended to replace the original factory-fitted side skirt to ensure the installation fit. The repair cost is relatively low but the effect is limited, while the replacement cost is higher but the effect is more lasting.
Material differences
Youdaoplaceholder0 plastic/metal : Minor damage can be repaired by itself or with a touch-up pen.
Youdaoplaceholder0 aluminum alloy : It usually needs to be replaced as a whole because of the difficulty and high cost of repair.
It is recommended to first determine the material and then select the corresponding treatment method, and handle it in time to avoid further damage to the chassis components or impact on the wind resistance performance.
