When the protrusion 105 is arranged at the end of the bottom shell 100 in the first direction, it is located on the outside of the bottom shell 100, so the buckle plate 206 needs to be arranged on the outside corresponding to the end of the LED panel 200. When the protrusion 105 is disposed at the end of the grille bar 104 in the first direction, the gusset plate 206 is also disposed on the LED panel 200, but the more specific correspondence is that the light bar 204 is connected to correspond to the grille bar 104, so the gusset plate 206 is disposed at the end of the LED panel 200 or the end of the light bar 204 corresponding to the protrusion 105. It can be understood that when the protrusion 105 is disposed at the end of the bottom case 100 and the end of the grille bar 104, the gusset plate 206 is also disposed at the end of the LED panel 200 and the end of the light bar 204.

[0038] In some embodiments of the present invention, the protrusions 105 are provided at both ends of the bottom shell 100, the size of the LED panel 200 along the first direction is the same as that of the bottom shell 100, and the buckle plate 206 is provided on the outside of the LED panel 200, so as to fit the side walls of both ends of the bottom shell 100 and buckle the protrusions 105. It can be understood that, since the protrusions 105 are located at both ends of the bottom shell 100 in the first direction, and the size of the LED panel 200 in the first direction is the same as that of the bottom shell 100, the inner walls of the buckle plates 206 located at both ends of the LED panel 200 in the first direction are kept flush with the outer wall of the bottom shell 100, and when the protrusions 105 are buckled, they will fit the outer wall of the bottom shell 100, so as to achieve both snap connection and position limiting, and the reliability is strong.

[0039] In some embodiments of the present invention, along the first direction, the grille bar 104 and the light bar 204 have the same size, and the first hollow slot 102 and the second hollow slot 202 have the same size, so that the first hollow slot 102 is directly opposite to the second hollow slot 202 along the front-to-back direction, and the light bar 204 fits the grille bar 104. By adopting the structural setting of this embodiment, the size can be controlled to ensure that the grille bar 104 supports the light bar 204, ensure its structural strength, and at the same time ensure the formation of the front and rear hollow air ducts.

[0040] In some embodiments of the present invention, the second clamping structure includes a clamping hook 205 . The clamping hook 205 is disposed on the back side of the second connecting rib 201 . The clamping hook 205 has a clamping step for clamping the back side of the first connecting rib 101 .

[0041] Specifically, along the second direction, the second connecting rib 201 is misaligned with the first connecting rib 101, so that the hook 205 fits the side wall of the first connecting rib 101. The side wall of the second connecting rib 201 and the side wall of the first connecting rib 101 remain aligned in the case of misalignment, and the hook 205 has the same width as the second connecting rib 201, and is formed by extending backward from the back of the second connecting rib 201, that is, it is integrally arranged with the second connecting rib 201, so that the hook 205 can fit the side wall of the first connecting rib 101 while being engaged with the back of the first connecting rib 101 through the buckling step, which is conducive to ensuring the strength of the engagement and the reliability of the structure.

[0042] In some embodiments of the utility model, a hook 205 is provided on the back of each second connecting rib 201, and in the same second hollow groove 202, the hook 205 on the second connecting rib 201 is located on the same side of the first connecting rib 101, and between two adjacent second hollow grooves 202, the hook 205 in one second hollow groove 202 is located on one side of the first connecting rib 101, and the hook 205 in the other second hollow groove 202 is located on the other side of the first connecting rib 101. With the structural setting of this embodiment, the hook 205 can be used to improve the connection strength between the LED panel 200 and the bottom shell 100, and the direction of the hook 205 is set to be the same direction in the same groove and the opposite direction in the adjacent groove, which is conducive to improving the convenience of disassembly and assembly of the LED panel 200 and ensuring the limiting strength in the second direction.

[0043] In some embodiments of the utility model, a plurality of grooves are provided on the front end surface of the second connecting rib 201. The length direction of the grooves extends along the second direction, and the plurality of grooves are arranged along the first direction. The grooves can further reduce wind resistance and improve the wind resistance of the grille screen.

[0044] In some embodiments of the present invention, the bottom shell 100 is provided with support parts 103 at both ends along the second direction, the first hollow groove 102 is provided between the two support parts 103, the LED panel 200 is provided with a reinforcing part 203 that fits the support part 103, the second hollow groove 202 is located between the two reinforcing parts 203, and the light bar 204 extends to the end of the reinforcing part 203 along the second direction. It can be understood that since both the LED panel 200 and the bottom shell 100 are provided with hollow grooves, it is inevitable that the structural strength thereof will be affected. In this embodiment, the support parts 103 are retained at both ends of the bottom shell 100, and the hollow grooves are not provided on the support parts 103, so that the structural strength thereof can be ensured. Similarly, the LED panel 200 is provided with a corresponding reinforcing part 203, and the hollow grooves are not provided on the reinforcing part 203, so that the structural strength thereof can be ensured. In addition, the bottom shell 100 can also meet the support requirements of the LED panel 200 in a strong wind environment.

Specifically, the four top corners of the LED panel 200 are provided with mounting holes, the bottom shell 100 is provided with threaded holes corresponding to the mounting holes, and the LED panel 200 is provided with screws for connecting the threaded holes from the front. With the structural setting of this embodiment, the bottom shell 100 and the LED panel 200 can be reinforced with connecting screws. When maintaining, only four connecting screws need to be removed. Compared with the traditional structure, the number of screws is greatly reduced, so the convenience of maintenance can be greatly improved.

[0046] In some embodiments of the present invention, a magnetic module is provided between the LED panel 200 and the bottom shell 100, and the magnetic module is used for reinforcement. With the structural setting of this embodiment, the magnetic module is used in conjunction with the first clamping structure and the second clamping structure to ensure the installation stability of the LED panel 200.

[0047] In summary, the clip-on grille screen in the utility model has the following advantages:

[0048] 1. The traditional connection method of a large number of screws is improved to a clamping method, which is convenient for disassembly and maintenance. On this basis, a small number of screws or magnetic suction can be further combined to strengthen the installation firmness of the LED panel 200 on the bottom shell 100;

[0049] 2. The first clamping structure is disposed at both ends of the bottom shell 100 and the LED panel 200 in the first direction, i.e., the upper and lower ends, and the second clamping structure is disposed between the first connecting rib 101 and the second connecting rib 201, and is limited in the second direction, i.e., the left and right directions, so that the installation stability of the LED panel 200 is reliable;

[0050] 3. The left and right hooks 205 are used to limit the first connecting rib 101 and the second connecting rib 201. Therefore, there is no need to set a structure such as a hook 205 in the corresponding upper and lower width directions of the hollow groove, which is beneficial to increase the area ratio of the hollow groove and improve the wind resistance performance. At the same time, multiple clamping positions are evenly distributed between the bottom shell 100 and the LED panel 200, and the structural strength can meet the requirements of strong wind environment.

[0051] The present invention is described in detail above in conjunction with the embodiments, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
