[0002] The front anti-collision beam is an important part of the vehicle safety system, mainly used to absorb and disperse the impact force when the vehicle is impacted, so as to protect the internal structure of the vehicle and the safety of the occupants.

[0003] The radiator grille, also often referred to as the upper grille, is an important part of the vehicle cooling system. It is located at the front end of the vehicle and is usually integrated into the front bumper. In the prior art, the upper part of the radiator grille is usually connected to the mounting bracket on the front anti-collision beam, which can play a certain role in supporting and preventing the front bumper from sagging.

[0004] However, since a structure facilitating connection with the mounting bracket on the front anti-collision beam needs to be provided on the radiator grille, the structure of the radiator grille is relatively complex. At the same time, the injection mold is required in the processing process of the radiator grille, resulting in a complex structure of the injection mold, not only with high design and manufacturing costs but also low service life.

In terms of the overall structure, the heat dissipation grille mounting structure in this embodiment mainly includes a first mounting bracket 1 and a second mounting bracket 2. Among them, the first mounting bracket 1 is used to be mounted on the front bumper beam 3, and the second mounting bracket 2 is provided with a pre-installation part 2021 and a connection part 2022. The second mounting bracket 2 is pre-installed on the heat dissipation grille 4 through the pre-installation part 2021 and is detachably connected to the heat dissipation grille 4 through the connection part 2022. The first mounting bracket 1 and the second mounting bracket 2 are detachably connected, enabling the heat dissipation grille 4 to be mounted on the front bumper beam 3.

[0055] To improve the convenience of connection between the first horizontal plate 101 and the second horizontal plate 201, as a preferred implementation manner, as Figure 4 and Figure 5 shown, the first horizontal plate 101 is provided with an opening 1011, and an elastic snap piece 1012 is provided at the edge of the opening 1011 close to the front bumper beam 3. The elastic snap piece 1012 is generally in a horizontally placed "S" shape and extends from the edge of the opening 1011 towards the side away from the front bumper beam 3, that is, the side where the heat dissipation grille 4 is located.

[0056] Meanwhile, asFigure 6 and Figure 7 As shown in Figure 7 , a clamping hole 2011 is provided on the second transverse plate 201. The clamping hole 2011 is strip-shaped, and its length direction extends along the left-right direction of the vehicle. With such a setting, when the first mounting bracket 1 and the second mounting bracket 2 are connected, the second transverse plate 201 is inserted between the first transverse plate 101 and the elastic clamping piece 1012, and a part of the elastic clamping piece 1012 can be clamped into the clamping hole 2011, so that the first mounting bracket 1 and the second mounting bracket 2 are clamped and connected.

The first connecting piece is preferably a bolt pair, which is beneficial to improving the stability of the installation of the first mounting bracket 1 on the front anti-collision beam 3. And each strip-shaped hole 1021 extends along the height direction of the vehicle, so that the installation height of the first mounting bracket 1 on the front anti-collision beam 3 is adjustable, which is convenient for adjusting the assembly accuracy and can adapt to a variety of different vehicle models.

[0060] Continuing to refer to Figure 4 and Figure 5 As shown in Figure 5 , as a preferred embodiment, at least one of the first transverse plate 101 and the first longitudinal plate 102 is provided with a reinforcing rib 103, and flanges 104 are provided on both sides of at least one of the first transverse plate 101 and the first longitudinal plate 102. In this structure, the arrangement of the reinforcing rib 103 and the flange 104 on the first transverse plate 101 and the first longitudinal plate 102 is beneficial to improving the structural strength of the first mounting bracket 1 and is beneficial to improving the stability and reliability of the support for the radiator grille 4.

[0061] In this embodiment, the first horizontal plate 101 is provided with reinforcing ribs 103, which are located in the middle of the first horizontal plate 101 in the left-right direction of the vehicle and extend in the height direction of the vehicle. In addition, two reinforcing ribs 103 are also provided at the connecting portion 2022 between the first horizontal plate 101 and the first vertical plate 102. These two reinforcing ribs 103 are arranged at intervals in the left-right direction of the vehicle, and have a good effect of improving the structural strength of the first mounting bracket 1.

[0062] It should be noted that the shape and quantity of the reinforcing ribs 103 on the first horizontal plate 101 can also be adjusted according to actual needs. Reinforcing ribs 103 can also be arranged on the first vertical plate 102 according to actual needs, or only reinforcing ribs 103 can be provided on the first vertical plate 102.

[0063] In a preferred embodiment, flanges 104 are provided on both the left and right sides of the first horizontal plate 101 and both the left and right sides of the first vertical plate 102, which can preferably improve the structural strength of the first mounting bracket 1 itself.

[0065] Here, the provided second vertical plate 202 and the plurality of connecting holes are conducive to ensuring the stability and reliability of the installation of the second mounting bracket 2 on the radiator grille 4. In this embodiment, the number of connecting holes is four, and the four connecting holes are arranged at intervals in the left-right direction of the vehicle, which can preferably ensure the stability and reliability of the installation of the second mounting bracket 2 on the radiator grille 4. It should be understood that the number and arrangement manner of the connecting holes can also be set in other ways as long as the second mounting bracket 2 can be stably installed on the radiator grille 4.

[0066] To improve the assembly efficiency of the second mounting bracket 2 on the radiator grille 4, as a preferred implementation, the pre-installation part 2021 includes a plurality of pre-installation holes provided on the second vertical plate 202. The plurality of pre-installation holes are arranged at intervals in the longitudinal direction of the vehicle. The radiator grille 4 is provided with extension posts 401 extending towards the interior of the vehicle. The extension posts 401 are arranged in one-to-one correspondence with the pre-installation holes. Each pre-installation hole is sleeved on the corresponding extension post 401, and the second mounting bracket 2 can be pre-installed on the radiator grille 4.

[0067] In the above structure, the pre-installation part 2021 is set as pre-installation holes, and the pre-installation holes are sleeved on the extension posts 401 of the radiator grille 4, so that the second mounting bracket 2 can be pre-hung on the radiator grille 4, which is not only beneficial to improving the installation efficiency and installation accuracy of the second mounting bracket 2 on the radiator grille 4, but also the pre-installation process is simple and convenient.

[0068] In this embodiment, the pre-installation holes are strip-shaped holes 1021. Each strip-shaped hole 1021 extends along the left-right direction of the vehicle, which is beneficial to improving the hanging stability of the second mounting bracket 2 on the radiator grille 4. There are three pre-installation holes, and the three pre-installation holes are arranged at intervals in the left-right direction of the vehicle, which is also beneficial to improving the hanging stability of the second mounting bracket 2 on the radiator grille 4. It should be understood that it is also feasible to set the shape of the pre-installation holes to other shapes, such as circular holes, square holes, etc. And the number of pre-installation holes can also be set to other values, such as one, two, four, etc.

[0069] To improve the structural strength of the second mounting bracket 2 itself, as Figure 6 shown, as a preferred implementation, a plurality of reinforcing plates 203 are connected between the second horizontal plate 201 and the second vertical plate 202. The plurality of reinforcing plates 203 are arranged at intervals in the left-right direction of the vehicle. Each reinforcing plate 203 is connected to the second horizontal plate 201 and the second vertical plate 202 respectively through its adjacent two sides.

[0070] In this embodiment, the number of the reinforcing plates 203 is six. The shape of each reinforcing plate 203 is generally a right triangle. The adjacent two right sides are respectively connected to the second horizontal plate 201 and the second vertical plate 202, and the reinforcing plates 203, the second horizontal plate 201 and the second vertical plate 202 are arranged orthogonally to each other, which is beneficial to better improving the structural strength of the second mounting bracket 2 itself. It should be understood that it is also feasible to set the number of the reinforcing plates 203 to other values, and the shape of the reinforcing plates 203 can also be set to other shapes, such as trapezoids.

It should be understood that the number of the first mounting bracket 1 and the second mounting bracket 2 can also be set to other values, such as one, three, five, etc.

[0073] In order to reduce the maintenance cost, as a preferred embodiment, the first mounting bracket 1 is made of a metal material, such as aluminum, steel, etc., and the second mounting bracket 2 is made of a plastic material, and its material can be the same as that of the radiator grille 4 or other plastic materials.

[0074] With such a setting, the first mounting bracket 1 is mainly used to ensure stable support for the radiator grille 4, while the second mounting bracket 2 can play a role of collapsing and absorbing energy during a vehicle collision, and can be damaged first to protect the radiator grille 4. Thus, during vehicle maintenance, only the second mounting bracket 2 needs to be replaced without replacing the radiator grille 4, and the maintenance cost is relatively low.

[0075] Finally, it should be supplemented that in this embodiment, mainly introduced is how the upper part of the radiator grille 4 is connected to the front bumper beam 3. It should be understood that the installation methods of the other parts of the radiator grille 4 on the vehicle can refer to the structures in the prior art.
