What is the lower guard plate of the rear bumper of a car
The guard plate beneath the rear bumper of a car is usually called a deflector (also known as a rear bumper liner or reinforcing plate), which is mainly fixed to the vehicle with screws or clips.
Functions and Features
Youdaoplaceholder0 Protective function : reduces damage caused by collisions or scratches on the bottom of the vehicle.
Youdaoplaceholder0 detachability : When a component is damaged, there is no need to replace the entire bumper; the deflector can be directly replaced.
Youdaoplaceholder0 Appearance optimization : Some designs combine aerodynamic functions with the aesthetic effect of the vehicle body appearance.
This component is mostly made of black plastic and is commonly found at the bottom of vehicles to enhance driving stability and reduce wind resistance.
The main functions of the rear bumper lower guard plate (also known as the deflector plate) of a car include:
Reduce lift
By optimizing the airflow under the vehicle, the lift force generated by the vehicle during high-speed driving is reduced, preventing the rear wheels from floating and enhancing driving stability.
Protective effect
It serves as a buffer in the event of a collision or scratch, reducing damage to the bottom of the vehicle body.
Keep the engine compartment clean
Prevent foreign objects from splashing into the engine compartment during driving to avoid affecting engine performance.
The repair method for the lower guard plate of the rear bumper of a car should be selected based on the degree of damage:
Slightly damaged
If only a small area of damage occurs, local repair can be considered instead of replacing the entire component.
Severely damaged
If the frame has not fallen off but the damaged area is large, it is recommended to replace it with a new guard plate to protect the chassis and engine.
Replacement steps
Contact the car manufacturer to obtain original factory parts
Use a screwdriver to remove the old guard plate and install the new one
Make sure the bolts are securely fastened and coated with anti-rust paint
It is recommended to choose a professional technician to operate to avoid secondary damage caused by self-repair.
The repair method for the damage to the lower guard plate of the rear bumper of a car should be determined based on the extent of the damage:
Minor damage treatment
If the damaged area is small, local repair can be considered. Use special tools (such as screwdrivers or wrenches) to remove the old guard plate, replace it with a new one and then re-fix it.
Treatment of severe damage
If the guard plate has large cracks or is completely damaged, the entire component needs to be replaced. It is recommended to contact the car manufacturer to obtain the original factory parts model to ensure that the size matches. When replacing, be careful to avoid tightening the bolts too tightly to prevent deformation of the components.
Cost consideration
Precautions
After replacement, check the tightness to avoid loosening
When it comes to body structure components, it is necessary to ensure that reserved deformation space is provided (such as engine sinking technology)
Give priority to brand guard plates with crumple design to ensure safety
The plastic plate under the rear bumper is usually called a spoiler , and its main function is to optimize the vehicle's aerodynamic performance and enhance driving stability.
Youdaoplaceholder0 Definition and function of the deflector plate
The plastic plate beneath the rear bumper is commonly referred to in automotive terminology as a spoiler (some materials also call it a rear bumper liner or reinforcing plate). Its core function is to reduce the air pressure under the vehicle at high speed through aerodynamic design, thereby lowering lift, preventing the rear wheels from floating, and enhancing the vehicle's grip and stability.
Youdaoplaceholder0 Structure and installation method
Youdaoplaceholder0 Physical properties : The deflector plates are mostly made of black plastic and are inclined downward. They are fixed to the bottom of the bumper with screws or clips.
Youdaoplaceholder0 Modular design : if damaged, it can be replaced separately without the need to replace the entire bumper.
Youdaoplaceholder0 Extended function
Youdaoplaceholder0 Safety protection : Absorb impact force in collision to protect pedestrians and drivers and passengers.
Youdaoplaceholder0 Aesthetics and weight reduction : Optimize the exterior lines of the vehicle body, while the lightweight design reduces the overall weight of the vehicle.
