Car rear bumper under body frosted belt hole action
The main function of the body frosted belt hole under the rear bumper of the car includes the following aspects :
anemological design : under the action of anemological, these holes can effectively disperse heat wave, prevent the temperature of the fuel tank and the rear part of the car from rising abnormally, so as to ensure the stable temperature in the car and driving safety .
trailer hook installation : These holes are designed to facilitate the installation of the trailer hook. When the vehicle fails to drive, the external cover can be easily removed and the tow hook installed for other vehicles to tow .
rear probe wire layout : holes in some vehicles are specially used for rear probe wire layout. If these holes are blocked, water may enter the trunk and need to be blocked using repair glue, and check and clean the diversion chutes and drainage outlets that may be blocked .
aerodynamic design : These holes are designed on the basis of aerodynamic principles to cut areas of low wind resistance in front of the wheels at high speeds, reducing air turbulence that interferes with the wheels and thereby reducing drag .
The main function of the body under the rear bumper of the car frosted belt hole includes the following aspects :
Heat dissipation and protection tank : these holes under the action of wind help to disperse the heat wave, protect the fuel tank and tail temperature is not too high, so as not to affect the temperature inside the car and driving safety .
installation of trailer hook : these holes are usually designed for trailer holes, when the vehicle is broken down can not run normally, you can remove the outside cover, install the trailer hook, convenient for other vehicles to tow .
wire holes : The holes in the rear bumper of some vehicles are specially designed for the rear probe lines, and need to be filled or inspected if the blockage may cause water to enter the trunk .
Reduced drag : These holes are part of an aerodynamic design designed to cut areas of low drag in front of the wheels at high speeds, reducing air turbulence .
The structure and material of automobile rear bumper :
The rear bumper of a car usually consists of a housing, cushioning material and a beam. The shell part is consistent with the appearance of the body and has a cushioning effect; The interior is equipped with a strengthening beam and other structures to improve the overall strength and stability, effectively resist collisions of different strengths, and ensure the safety of the rear of the vehicle .
The rear bumper has a variety of materials and lightweight plastic texture, which can reduce the weight of the vehicle and improve fuel efficiency; Metal materials are stronger and can withstand greater impact, but the cost is higher .
Maintenance and repair suggestions :
In daily maintenance, the status of the bumper should be checked regularly to keep it clean, and scratches and minor damage should be found and treated in time. For minor scratches, they can be repaired by grinding and painting. If the bumper is severely cracked or deformed, it may need to be replaced with a new part .
