The decorative panel 1 and the decorative panel 2 are split structures. After being positioned and connected to each other by snaps, they are fixed together by bolts. In this way, the shortcomings of the integral lower decorative panel, such as being heavy and difficult to process, are improved, and the difficulty of assembling the subsequent integral lower decorative panel is reduced, making the assembly process more flexible. By separately processing the decorative panel 1 and the decorative panel 2, more decorative strips, decorative surfaces, etc. can be designed on the decorative panel 1 and the decorative panel 2, and the decorative effect is stronger. At the same time, the anti-collision flange 21 provided can reduce the lift generated by the car when it is driving at high speed, and improve the stability of the car by improving the aerodynamic performance of the vehicle.

[0042] In this embodiment, the upper edge of the decorative plate 1 is provided with a plurality of slot holes 13, and the slot holes 13 are engaged with the buckles on the front bumper. This design allows the decorative plate 1 to be easily fixed to the bottom of the bumper by the buckles, so that if the decorative plate 1 is damaged or lost during use, the decorative plate 1 can be removed and repaired or replaced, so that the vehicle can be used normally more quickly. In addition, this design also facilitates the daily inspection and maintenance of the car owner or maintenance personnel, and improves the convenience of maintenance.

[0043] In this embodiment, a decorative strip 14 is provided on the decorative panel 1, and the decorative strip 14 is arranged on both sides of the air inlet 11. The decorative strip 14 can increase the aesthetic appearance of the lower decorative panel. At the same time, it protects the surface of the lower decorative panel where the decorative strip 14 is provided, reduces damage to the paint surface of the lower decorative panel caused by bumps on the surface, and the decorative strip 14 that is higher than the surface of the lower decorative panel can also play a role in strengthening the strength of the surface, thereby preventing the surface of the lower decorative panel from being deformed due to high temperature, extrusion and other factors, affecting the appearance.

[0044] In this embodiment, the air intake hole 11 includes an air intake hole 111 and an air intake hole 2 112. The air intake hole 111 is arranged in the middle position of the decorative panel 1, and the air intake hole 2 12 is symmetrically arranged on both sides of the air intake hole 111.

It can assist the air intake grille in the driving process of the car, ensure that the air can smoothly enter the engine compartment, and ensure that the water tank, engine, air conditioner and other components have sufficient air intake ventilation. At the same time, due to the arrangement of the air intake hole 11, the decorative panel 1 has a corresponding hollow structure, and also the decorative panel 1 has a certain deformation space. When the decorative panel is slightly impacted or squeezed to cause deformation, it can automatically restore to its original state through its own hollow structure and material properties, thereby increasing its service life.

[0045] In this embodiment, a positioning column 15 is provided on the inner side surface of the decorative panel 1, and the positioning column 15 is plugged and fixed to the corresponding position on the buffer frame 3. The buffer frame 3 is made of foam material, and is arranged at the connection between the decorative panel 1 and the decorative panel 2 and is located behind the anti-collision flange 21. Its function is to provide a buffer area for pedestrians in the event of an accidental collision to reduce possible injuries to pedestrians. At the same time, the rear of the anti-collision flange 21 is connected to the anti-collision steel beam to provide support for the entire lower decorative panel.

[0046] In this embodiment, both ends of the decorative panel 2 are located below the decorative surface 4, and the main body of the decorative panel 2 is located below the decorative panel 1. The front bumper is an important part of the vehicle body design. The decorative surface 4 arranged at its corresponding position not only enhances the appearance of the vehicle, but also coordinates with other components to add a sense of fashion to the vehicle. When the vehicle encounters a low-speed collision or hits a pedestrian, the decorative surface 4 can reduce the impact force through its arc shape, protect the pedestrian and the vehicle body from damage, and at the same time, when colliding with a pedestrian, it can also provide a certain degree of pedestrian protection. The structural design that bends toward the vehicle body helps to optimize the aerodynamic performance of the vehicle, reduce wind resistance, and improve driving stability.

[0047] In this embodiment, a plurality of hooks 24 are provided on the inner side surface of the decorative panel 2, and the hooks 24 are engaged with the corresponding slots on the decorative panel 1, and a fastening pad is provided inside the hook 24, and the hook 24 is located on the fastening pad. This design allows the decorative panel 2 to be easily fixed to the bottom of the decorative panel 1 through the hook 24. In this way, if the decorative panel 2 is damaged or lost during use, the decorative panel 2 can be removed and repaired or replaced separately, so that the purpose of normal use can be achieved more quickly. In addition, this design also facilitates daily inspection and maintenance by the owner or maintenance personnel, thereby improving the convenience of maintenance.

[0048] The fastening pad is set, after the hook 24 is assembled, it can support the hook 2 through elastic force, so that the position of the hook 24 is fixed, and the decorative panel 1 and the decorative panel 2 2 are prevented from loosening due to the loosening of the hook 24, which affects the life of the lower decorative panel of the vehicle and the driving experience.

[0049] The root of the fastening pad is fixedly connected to the main body of the decorative panel 1 and when subjected to external force, the force can be transmitted to the entire decorative panel 1, thereby reducing the possibility of damage to the fastening panel.

[0050] In this embodiment, the air intake hole group 22 includes a circular hole group located in the middle of the decorative plate 2 and rectangular holes symmetrically arranged on both sides of the decorative plate 2. The air intake hole group 22 can assist the air intake of the air intake grille during the driving process of the car, ensure that the air can smoothly enter the engine compartment, and ensure that the water tank, engine and air conditioner and other components obtain sufficient air intake ventilation. At the same time, due to the setting of the air intake hole 11, the decorative plate 1 has a corresponding hollow structure, which also makes the decorative plate 1 have a certain deformation space. When the decorative plate 1 is slightly impacted or squeezed to produce deformation, it can automatically restore to its original state through its own hollow structure and material properties, thereby increasing the service life. At the same time, the circular hole set in the front can provide better air flow efficiency, reduce the resistance of air flow, and allow air to enter the engine compartment more smoothly, thereby improving the heat dissipation efficiency and performance in the engine compartment. In addition, the design of the circular air intake hole is also more beautiful, which can enhance the overall aesthetics and design sense of the equipment.

[0051] In this embodiment, the buffer frame 3 is provided with an avoidance groove corresponding to the position of the hook 24. The outline size of the avoidance groove is larger than the outline size of the hook 24 by 5-6 mm on one side. It can not only provide the necessary avoidance space for the hook 24, but also provide the necessary support for the decorative panel 22 when the decorative panel 22 is deformed, thereby preventing the hook 24 from being broken by the force and affecting the assembly.

[0052] In this embodiment, the anti-collision flange 21 protrudes from the decorative surfaces of the decorative panel 1 and the decorative panel 2, and the lower surface of the anti-collision flange 21 is a slope inclined downward, which expands the range of the high-speed and low-pressure airflow under the vehicle when it leaves the bottom of the vehicle and enters the rear of the vehicle, thereby slowing down the speed of the low-pressure airflow under the vehicle, generating downforce, and helping the vehicle to maintain stability when driving at high speed.

[0053] Based on the above, the decorative panel 1 and the decorative panel 2 provided in the invention are split structures, which are connected to each other by snap-fit ​​positioning and then fixed by bolts. By separately processing the decorative panel 1 and the decorative panel 2, the difficulty of subsequent assembly of the overall lower decorative panel is reduced, making the assembly process more flexible; the air intake holes and the air intake hole group provided in the invention can assist the air intake grille at the front bumper position during the driving of the car, ensure that the air can smoothly enter the engine compartment, and ensure that components such as the water tank, engine and air conditioner obtain sufficient air intake ventilation; the anti-collision flange in the present invention can protect the overall lower decorative panel structure, and the forward arched structure can also reduce the lift generated by the car when the car is driving, thereby stabilizing the body.
