DETAILED DESCRIPTION

[0042] In the absence of conflict, the embodiments and technical features in the embodiments of the present application may be combined with each other, and the detailed descriptions in the specific implementation methods should be understood as explanations of the purpose of the present application and should not be regarded as improper limitations on the present application.

[0043] It should be noted that in the embodiments of the present application, the orientations or positional relationships such as "axial", "first side", "second side", "inside", and "outside" in the embodiments of the present application are based on the orientations or positional relationships shown in the accompanying drawings. It should be understood that these orientation terms are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. The present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. In addition, the terms "first", "second", etc. are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0044] In the related art, it is difficult to install the ventilation grille and the decorative ring of the air conditioner outdoor unit. It is difficult to align the decorative ring with the ventilation grille, and after installation, the decorative ring is easy to protrude to the side, that is, radially outward, affecting the appearance of the product.

[0045] The present application embodiment provides a ventilation mesh assembly 100, see Figure 1-Figure 12 The ventilation mesh cover assembly 100 includes a ventilation mesh cover 10 and a decorative ring 20. The ventilation mesh cover 10 includes a cover body 11 and an assembly body 12 surrounding the outer periphery of the cover body 11, the surface of the assembly body 12 facing the first side of the axial direction is an assembly surface 121, and the assembly surface 121 is formed with a protrusion 1211; the decorative ring 20 is arranged around the assembly surface 121, and the decorative ring 20 is formed with an annular limiting groove 20a opening toward the protrusion 1211, and the protrusion 1211 is accommodated in the limiting groove 20a.

[0046] The ventilation grille assembly 100 can be applied to an air conditioner outdoor unit, which is used to discharge indoor heat to the outside to achieve heat exchange and transfer and adjust the indoor temperature. For example, the outer contour of the ventilation grille 10 can be approximately circular or elliptical.

[0047] The outdoor unit of the air conditioner is usually installed outdoors. The ventilation mesh cover 10 can prevent debris from entering the interior of the outdoor unit of the air conditioner while achieving ventilation, thereby reducing the possibility of damage to the outdoor air conditioner.

[0048] The decorative ring 20 is used to decorate the assembly 12 of the ventilation grille 10 . The decorative ring 20 can shield the assembly 12 and improve the aesthetics. The decorative ring 20 can also reduce the possibility of damage to the assembly 12 and extend the service life of the ventilation grille 10 .

[0049] The assembly surface 121 is formed with a protrusion 1211, and the decorative ring 20 is formed with a limiting groove 20a. When installing the decorative ring 20, the protrusion 1211 can be aligned with the limiting groove 20a, which can greatly reduce the difficulty of installation. After installation, the protrusion 1211 can limit the limiting groove 20a, reduce the possibility of the decorative ring 20 protruding to both sides of the radial direction, and thus improve the limiting effect of the decorative ring 20.

[0050] In this embodiment, the difficulty of assembly can be reduced by cooperating with the limiting groove 20a and the protrusion 1211 during installation. After assembly, the limiting effect of the protrusion 1211 on the limiting groove 20a can limit the decorative ring 20, so as to reduce the possibility of the decorative ring 20 protruding radially outward, and improve the structural stability of the ventilation mesh cover assembly 100 after assembly; the decorative ring 20 and the assembly body 12 are limited by the protrusion 1211 and the limiting groove 20a, and the assembly gap between the two is small, which can also reduce the noise caused by the vibration of the air-conditioning outdoor unit due to the poor limiting effect of the decorative ring 20 after assembly.

[0051] Exemplarily, a plurality of protrusions 1211 are arranged at intervals along the assembly surface 121 to further reduce the difficulty of installation, improve the limiting effect of the protrusions 1211 on the decorative ring 20, and reduce the possibility of the decorative ring 20 protruding radially outward.

[0052] For some examples, see Figure 3 The decorative ring 20 includes an outer flange 21, an inner flange 22 and a connecting edge 23, all of which are annular. The outer flange 21 is located radially outside the inner flange 22. The connecting edge 23 connects the outer flange 21 and the inner flange 22 to define a limiting groove 20a. The decorative ring 20 has a simple structure and is easy to manufacture.

[0053] For example, the cross section of the connecting edge 23 is an arcuate edge, and the arcuate edge is concave toward the outer flange 21, so that it is easy to operate during installation. For example, the arcuate edge can be pressed to fix the decorative ring 20 and the ventilation grille 10.

[0054] In some embodiments, in the axial direction, the first end of the outer flange 21 near the first side protrudes beyond the first end of the inner flange 22 near the first side; the connecting edge 23 connects the first end of the outer flange 21 and the first end of the inner flange 22. Thus, the cross-sectional shape of the limiting groove 20a is generally V-shaped.

[0055] In this way, the outer flange 21, the inner flange 22 and the connecting edge 23 can form a tendency to tilt outward, which guides the ventilation airflow and reduces the influence of the decorative ring 20 on the ventilation effect.

[0056] Exemplarily, the outer flange 21 is arranged along the ventilation direction, and the inner flange 22 is inclined toward the outer flange 21 to reduce the adverse effect on the ventilation effect. It can be understood that the ventilation direction can be axially from the second side toward the first side. Figure 3 Here, Y1 represents the first side, and Y2 represents the second side.

[0057] In some embodiments, the decorative ring 20 has a first clamping portion, the assembly body 12 has a second clamping portion, and the first clamping portion and the second clamping portion are clamped.

[0058] By clamping the first clamping portion and the second clamping portion, the stability of the connection between the decorative ring 20 and the assembly 12 can be improved, the operation convenience can be improved, and the installation efficiency can be improved.

[0059] In some embodiments, a plurality of second clamping parts are spaced apart along the circumferential direction, and at least one protrusion 1211 is provided between two adjacent second clamping parts. In this way, by providing a plurality of second clamping parts to cooperate with the first clamping parts, the fixing effect of the decorative ring 20 and the ventilation mesh cover 10 can be improved, and the possibility of displacement of the decorative ring 20 can be reduced. The protrusion 1211 limits the radial deformation of the part between two adjacent second clamping parts, and the reliability is higher.

[0060] Exemplarily, when installing the decorative ring 20 , after the limiting groove 20 a and the protrusion 1211 are aligned, the first clamping portion and the second clamping portion are aligned and then clamped to achieve the installation of the decorative ring 20 .

[0061] There is at least one protrusion 1211 between the two second clamping parts, which can improve the limiting effect of the protrusion 1211 on the limiting groove 20a and reduce the possibility of displacement of the decorative ring 20 relative to the ventilation mesh cover 10 after installation.

[0062] It can be understood that by aligning one set of the first clamping parts with the second clamping parts, the remaining first clamping parts can also be aligned with the corresponding second clamping parts, which can reduce the difficulty of installation and reduce the installation time.

[0063] In some embodiments, one of the first clamping portion and the second clamping portion is a buckle 24, and the other of the first clamping portion and the second clamping portion is a first bayonet 12a, and the buckle 24 is engaged with the first bayonet 12a.

[0064] The buckle 24 is engaged with the first bayonet 12a, which can improve the fixing effect of the decorative ring 20 and the ventilation mesh cover 10. The installation can be completed by pressing, which is convenient for installation and disassembly.

[0065] For example, see Figure 5 and Fig.11 The first clamping portion is the buckle 24, and the second clamping portion is the first clamping port 12a.

[0066] Exemplarily, the first clamping portion is the first clamping opening 12 a , and the second clamping portion is the buckle 24 .

[0067] For some examples, see Fig.12The buckle 24 includes an elastic arm 241 and a clamping platform 242. One of the decorative ring 20 and the assembly 12 has a first clamping portion. One end of the elastic arm 241 is connected to the first clamping portion. The clamping platform 242 is connected to the free end of the elastic arm 241. Under the action of the pressing force along the axial direction, the clamping platform 242 moves from one side of the first clamping port 12a to the other side of the axial direction, so that the surrounding part of the first clamping port 12a is clamped between the first clamping portion and the clamping platform 242.

[0068] After aligning the buckle 24 with the first bayonet 12a, the base 242 is pushed through the first bayonet 12a for easy operation. After installation, the first clamping portion and the base 242 can clamp the surrounding area of ​​the first bayonet 12a, which can improve the fixing effect of the decorative ring 20 and the ventilation mesh cover 10 and further reduce the possibility of displacement of the decorative ring 20 relative to the ventilation mesh cover 10.

[0069] Exemplarily, the decoration ring 20 has a first clamping portion.

[0070] Exemplarily, the assembly body 12 has a first clamping portion.

[0071] In some embodiments, one of the decorative ring 20 and the assembly 12 forms a positioning column 26, and the other of the decorative ring 20 and the assembly 12 forms a positioning groove 12b, and the positioning column 26 is accommodated in the positioning groove 12b. The positioning column 26 can further improve the speed of aligning the decorative ring 20 and the assembly 12, improve the installation speed, and reduce the difficulty of assembly.

[0072] Exemplarily, when installing the decorative ring 20 , after the limiting groove 20 a and the protrusion 1211 are aligned, the positioning column 26 is aligned with the positioning groove 12 b and then inserted, and the buckle 24 is inserted into the first bayonet 12 a to achieve a fixed connection between the decorative ring 20 and the ventilation mesh cover 10 .

[0073] For example, see Figure 6 and Fig.12 The decorative ring 20 forms a positioning column 26. The assembly body 12 is formed with a positioning groove 12b, and the positioning column 26 is accommodated in the positioning groove 12b.

[0074] For some examples, see Figure 13-Figure 20The ventilation mesh cover assembly 100 includes a panel 30, the panel 30 is formed with an air outlet 30a, the ventilation mesh cover 10 covers the air outlet 30a, one of the assembly 12 and the panel 30 is formed with a mounting piece 122, and the other of the assembly 12 and the panel 30 is formed with a second bayonet 30b; the mounting piece 122 includes a hook 1221, a second clamping portion 1222 and a convex hump 1223, the hook 1221 and the convex hump 1223 are both connected to the second clamping portion 1222, the suspended end 12211 of the hook 1221 and the second clamping portion 1222 are spaced apart along the axial direction; the surrounding portion of the second bayonet 30b is clamped between the suspended end 12211 and the second clamping portion 1222, and the convex hump 1223 abuts against the end surface of the surrounding portion of the second bayonet 30b away from the suspended end 12211 along the axial direction.

[0075] For example, see Figure 14-17 The assembly 12 is formed with a mounting piece 122, and the panel 30 is formed with a second bayonet 30b. During installation, the hook 1221 is passed through the second bayonet 30b, and the assembly 12 is rotated by clamping the second clamping portion 1222, so that the surrounding part of the second bayonet 30b is clamped between the suspended end 12211 and the second clamping portion 1222, and at the same time, the convex bump 1223 forms pressure toward the clamping part of the second bayonet 30b, so that the panel 30 and the assembly 12 are fixed. In this way, the fixing effect of the assembly 12 and the panel 30 can be improved.

[0076] It can be understood that when the assembly body 12 is formed with the mounting member 122 , the hook 1221 is located at the second side of the assembly body 12 along the axial direction.

[0077] Exemplarily, the panel 30 is formed with a mounting piece 122 , and the decorative ring 20 is formed with a second bayonet 30 b .

[0078] In some embodiments, please refer to the figure, the convex bump 1223 is located at the side where the opening of the hook 1221 is located.

[0079] In this way, the convex bump 1223 and the hook 1221 can apply pressure to the clamping portion of the second clamping port 30 b from both sides, thereby improving the fixing effect.

[0080] For some examples, see Fig.17 , the suspended end 12211 has a contact point 122111 protruding toward the second clamping portion 1222, and the distance between the convex bulge 1223 and the contact point 122111 is not less than 5 mm. In this way, the risk that the distance between the convex bulge 1223 and the contact point 122111 is too small, resulting in the peripheral part of the second bayonet 30b being unable to be inserted between the suspended end 12211 and the second clamping portion 1222, can be reduced. After the peripheral part of the second bayonet 30b is inserted into the suspended end 12211 and the second clamping portion 1222, the possibility of the suspended end 12211 breaking can be reduced.

[0081] Exemplarily, the distance between the convex hull 1223 and the abutment point 122111 may be 5 mm, 8 mm, 10 mm, 12 mm, or the like.

[0082] For some examples, see Fig.17 The second clamping portion 1222 has a slope 12221, which extends from the convex hump 1223 to the location of the suspended end 12211; the ventilation mesh cover 10 rotates relative to the panel 30 so that the surrounding part of the second bayonet 30b enters between the suspended end 12211 and the second clamping portion 1222 through the opening of the hook 1221 under the guidance of the slope 12221.

[0083] In this embodiment, the second clamping portion 1222 and the suspended end 12211 can improve the clamping effect of the second clamping portion 1222 on the surrounding area of ​​the second bayonet 30b through the inclined surface 12221. When the surrounding area of ​​the second bayonet 30b passes through the opening of the hook 1221, the inclined surface 12221 can guide the surrounding area of ​​the second bayonet 30b, thereby reducing the difficulty of assembling the decorative ring 20 and the panel 30.
