What is under the front bumper of a car
The body under the front bumper of an automobile is usually called the "deflector" . The deflector is a plastic plate installed under the bumper. Its main function is to reduce the air resistance generated by the car at high speed and improve the stability and handling of the vehicle . The deflector is usually attached to the body by screws or clasp and can be easily removed .
The design of the deflector can effectively reduce the lift of the vehicle and prevent the rear wheel from floating, thus ensuring the safety of the vehicle . In addition, it directs air flow so that it passes more smoothly under the car, reducing airflow resistance and improving fuel efficiency . The deflector is usually in the shape of a downward-sloping connector mounted below the front bumper .
The main functions of the front bumper body include protecting the front of the vehicle, reducing damage in a collision, beautifying the appearance of the vehicle, reducing lift at high speeds and improving the aerodynamic characteristics of the vehicle.
Firstly, protecting the front of the vehicle is one of its basic functions. The front bumper is designed to absorb and mitigate external shocks in the event of a crash, thereby protecting the front and rear parts of the body from serious damage . In addition, the front bumper also has a decorative role, making the vehicle appearance more beautiful .
Secondly, reducing the lift at high speed is another important role of the front bumper under body. A deflector (a plastic panel) installed under the front bumper reduces lift at high speeds, thereby preventing the rear wheels from floating and improving vehicle stability . By optimizing the air flow under the vehicle, the baffle not only improves the stability of the vehicle, but also improves the fuel efficiency to a certain extent .
Finally, improving the vehicle's aerodynamic characteristics is also an important function of the body under the front bumper. The deflector improves the aerodynamic performance of the vehicle by opening the appropriate air intake, increasing the excess air flow and reducing the pressure under the vehicle. This design not only improves the vehicle's aerodynamic performance, but also reduces drag at high speeds, thereby reducing fuel consumption .
The main reason for the failure of the body under the front bumper is external impact such as collision or scratching. As a protective device on the front of the vehicle, the bumper is easy to be damaged in traffic accidents or accidental collisions, resulting in cracking or cracking .
The manifestations of the fault include the bumper under the body cracking, cracking and so on. These damages not only affect the appearance of the vehicle, but may also affect its protective function .
Repair methods include plastic welding, metal welding or special fiberglass welding techniques, depending on the material of the bumper. After the repair, it will also need to be painted to restore the original appearance .
Preventive measures include regular inspection of the front bumper of the vehicle to detect and deal with potential damage in a timely manner. In addition, taking care to avoid collisions and scratches during driving can effectively reduce the risk of bumper damage .
