It can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to the specific circumstances.

[0048] As shown in Figures 1 to 13, the air duct cover provided by the present application includes a cover body 100 and a decorative panel, wherein the decorative panel is fixed to the cover body 100. The cover body 100 is provided with multiple fixing structures for fixing the decorative panel, and the multiple fixing structures are respectively adapted to install different decorative panels.

[0049] The cover plate body 100 includes an assembly surface for mounting the decorative panel. The plurality of fixing structures are all located on the assembly surface to fix the decorative panel to the assembly surface.

[0050] One of the fixing structures is a mounting groove 101 located on both sides and / or the top of the mounting surface along the width direction. The mounting groove 101 is recessed downward from the mounting surface. The mounting groove 101 is adapted to mount a decorative panel with a decorative strip. The position and depth of the mounting groove 101 can be adjusted to adapt to the decorative strip of the decorative panel.

[0051] Another fixing structure is a glue groove 102 provided on the mounting surface. This glue groove 102 is used to accommodate adhesive material to secure the decorative panel. This glue groove 102 is located inside the mounting groove 101, and the depth of the mounting groove 101 is greater than that of the glue groove 102. This glue groove 102 is suitable for mounting glass panels 300, metal panels 400, and the like.

[0052] The adhesive groove 102 is recessed downward from the mounting surface. It includes a transverse adhesive groove extending along the width of the mounting surface and a vertical adhesive groove extending along the height of the mounting surface. Double-sided tape or hot melt adhesive can be placed in the adhesive groove 102 to secure the decorative panel. Preferably, the depth of the adhesive groove 102 is 0.2-0.4 mm.

[0053] Another fixing structure is a welding groove 103 provided on the assembly surface. The welding groove 103 is located between the assembly groove 101 and the adhesive groove 102. The welding groove 103 extends along the height direction of the assembly surface. The welding groove 103 is suitable for installing a decorative panel with welding ribs 501.

[0054] The cover plate body 100 and / or the decorative panel are provided with a shielding member for shielding the assembly gap between the cover plate body 100 and the decorative panel.

[0055] In a specific embodiment, the shielding member is a retaining rib 104 extending from the assembly surface toward the decorative panel, and the retaining rib 104 is located outside the assembly groove 101 .

[0056] The bottom of the cover body 100 is provided with a positioning groove 106. The positioning groove 106 is located on the assembly surface and extends horizontally. When installing the decorative panel, the bottom end of the decorative panel is inserted into the positioning groove 106, thereby playing a pre-installation positioning role.

[0057] 1 to 8 , in a specific embodiment, the assembly groove 101 is used to mount a surface light source panel 200. The surface light source panel 200 includes a top trim strip at its top and side trim strips 201 on both sides along its width. The top trim strip is located between the two side trim strips 201. The top trim strip and the side trim strips 201 wrap around the edges of the surface light source panel 200. The surface light source panel 200 is fixed in the assembly groove 101 by the top trim strip and the side trim strips 201.

[0058] Correspondingly, the mounting grooves 101 are located at the top and on both sides of the mounting surface in the width direction. The mounting grooves 101 located on both sides of the mounting surface in the width direction extend along the height direction of the mounting surface, and the mounting grooves 101 on both sides are connected to the mounting groove 101 on the top, thereby forming a whole for mounting the surface light source panel 200. The top decorative strip is located in the mounting groove 101 at the top of the mounting surface. The side decorative strips 201 are located in the mounting grooves 101 on both sides of the mounting surface.

[0059] The top decorative strip can be an existing common decorative strip. The side decorative strip 201 serves as the shielding member to shield the assembly gap between the surface light source panel 200 and the assembly surface, and at the same time shield the retaining rib 104 located on the assembly surface.

[0060] The side trim 201 includes a first connection portion 201a, a second connection portion 201b, and a third connection portion 201c located between the first connection portion 201a and the second connection portion 201b. The second connection portion 201b is located in the assembly groove 101. The surface light source panel 200 is clamped between the first connection portion 201a and the second connection portion 201b.

[0061] The first connecting portion 201a and the second connecting portion 201b are parallel to each other. The third connecting portion 201c is connected to the same side of the first connecting portion 201a and the second connecting portion 201b, and the width of the first connecting portion 201a is smaller than the width of the second connecting portion 201b. The second connecting portion 201b is located in the assembly groove 101, and its width is compatible with the assembly groove 101. The width of the first connecting portion 201a can be adaptively adjusted as needed.

[0062] Preferably, the width of the first connecting portion 201a is 3-5 mm, and the width of the second connecting portion 201b is 8-12 mm.

[0063] Mounting holes 101a are provided at intervals in the assembly groove 101. The cover body 100 further includes a first fixing hole 105 located beside the mounting hole 101a.

[0064] The lateral trim 201 also includes a fixing portion 201d extending from the second connecting portion 201b toward the mounting surface. Each fixing portion 201d corresponds to each mounting hole 101a. The fixing portion 201d is perpendicular to the second connecting portion 201b. A second fixing hole 201e is defined in the fixing portion 201d. Preferably, the fixing portion 201d is 6 mm from the end of the second connecting portion 201b distal to the third connecting portion 201c.

[0065] The thickness of the third connecting portion 201c gradually increases from the first connecting portion 201a to the second connecting portion 201b. When the surface light source panel 200 is secured within the assembly slot 101 via the lateral decorative strips 201, only the third connecting portion 201c is visible from the side of the air duct cover. The obstructing bevel provided on the third connecting portion 201c shields the side edge of the surface light source panel 200 and the assembly interface between the surface light source panel 200 and the assembly surface, making the overall air duct cover more aesthetically pleasing.

[0066] A notch 201f is formed at the connection between the first connecting portion 201b and the third connecting portion 201c. When the surface light source panel 200 is fixed in the assembly groove 101 via the lateral decorative strip 201, the retaining rib 104 is located in the notch 201f, thereby shielding the retaining rib 104.

[0067] When installing the surface light source panel 200, the top decorative strip is placed in the assembly groove 101 at the top of the assembly surface, and the side decorative strips 201 are placed in the assembly grooves 101 on both sides of the assembly surface. The fixing portion 201d of the side decorative strip 201 passes through the mounting hole 101a in the assembly groove 101, and the second fixing hole 201e on the fixing portion 201d is coaxially aligned with the first fixing hole 105. Finally, screws or other fixing parts are passed through the first fixing hole 105 and the second fixing hole 201e to fix the surface light source panel 200.

[0068] 1, 2, and 9 to 11, the adhesive groove 102 is used to mount the glass panel 300. Double-sided tape or hot melt adhesive is placed in the adhesive groove 102, the bottom end of the glass panel 300 is inserted into the positioning groove 106, and the glass panel 300 is pressed against the mounting surface. The double-sided tape or hot melt adhesive is used to secure the glass panel 300.

[0069] An overflowing glue groove is further provided inside the glue groove 102. When hot melt glue is injected into the glue groove 102 for gluing and fixing the glass panel 300, the overflowing glue groove is used to prevent the hot melt glue from flowing freely during pressing and thus affecting the fixing effect.

[0070] When the glass panel 300 is pressed and fixed to the mounting surface, a large side gap exists between the glass panel 300 and the mounting surface due to the presence of the mounting groove 101. Therefore, the provision of the retaining rib 104 blocks the gap between the glass panel 300 and the mounting surface, namely the mounting groove 101, thereby improving the overall appearance of the air duct cover. Preferably, the retaining rib 104 is disposed perpendicular to the mounting surface.

[0071] Of course, the retaining rib 104 may also be provided on the glass panel 300. The retaining rib 104 extends from the glass panel 300 toward the mounting surface, and can also play a role in shielding the gap between the glass panel 300 and the mounting surface.

[0072] Since the surface light source panel 200 is fixed by screws and the glass panel 300 is fixed by adhesive, the conventional fixing structures on both sides of the width of the duct cover cannot coexist. However, the duct cover provided in this application achieves the coexistence of the fixing structures on both sides by staggering the assembly groove 101 and the adhesive groove 102 on the assembly surface, so that the adhesive groove 102 is located inside the assembly groove 101.

[0073] The thickness difference between the surface light source panel 200 and the glass panel 300 results in differences in the top and bottom interfaces of the air duct cover. Furthermore, the decorative strip 201 on the surface light source panel 200 further increases the thickness difference between the surface light source panel 200 and the glass panel 300, affecting the coexistence of the fixing structure.

[0074] The air duct cover provided in this application provides an assembly groove 101 on the assembly surface for accommodating the decorative strip 201, and increases the depth of the assembly groove 101, thereby creating a depth difference between the assembly groove 101 and the glue groove 102. This helps to unify the assembly dimensions of the surface light source panel 200 and the glass panel 300 in the thickness direction as much as possible, so that both can be adapted to the positioning groove 106 located at the bottom of the cover body 100. In this way, the air duct cover can simultaneously install the surface light source panel 200 and the glass panel 300 to meet different needs.

[0075] Referring to Figures 1, 2, and 12, the adhesive groove 102 is used to mount the metal panel 400. Double-sided tape or hot melt adhesive is placed in the adhesive groove 102. The bottom end of the metal panel 400 is inserted into the positioning groove 106 and pressed against the mounting surface. The double-sided tape or hot melt adhesive secures the metal panel 400. The retaining ribs 104 block the gap between the metal panel 400 and the mounting surface, i.e., the mounting groove 101, making the overall air duct cover more aesthetically pleasing.

[0076] In some embodiments, the metal panel 400 includes fixing pieces 401 spaced apart at both ends and a top of the metal panel 400 along a width direction, and the fixing pieces 401 extend toward the cover plate body 100 .

[0077] Specifically, the fixing piece 401 is arranged perpendicular to the metal panel 400. The fixing piece 401 includes a bending portion and a fixing portion, the fixing portion is connected to the metal panel 400 via the bending portion, and the width of the bending portion is smaller than that of the fixing portion.

[0078] After the metal panel 400 is glued to the assembly surface, the fixing piece 401 is bent toward the cover body 100, with the bent portion bent 90°. The fixing portion is then fitted onto the cover body 100, positioning the cover body 100 between the metal panel 400 and the fixing portion, thereby achieving enhanced fixation of the metal panel 400. Of course, in this embodiment, the metal panel 400 can also be fixed solely by the fixing piece 401.

[0079] 1 , 2 and 13 , the welding groove 103 is used to fix the plastic panel 500 . A welding rib 501 is provided on a surface of the plastic panel 500 corresponding to the assembly surface, and the assembly surface is provided with a welding groove 103 corresponding to the welding rib 501 .

[0080] When installing the plastic panel 500, the bottom end of the plastic panel 500 is inserted into the positioning groove 106, the plastic panel 500 is attached to the assembly surface, and the welding ribs 501 are aligned with the welding grooves 103. Finally, the plastic panel 500 is fixed by ultrasonic welding. The retaining ribs 104 cover the gap between the plastic panel 500 and the assembly surface, namely the assembly grooves 101, making the air duct cover more beautiful as a whole.

[0081] The arrangement of the welding ribs 501 and the welding grooves 103 includes, but is not limited to, horizontal arrangement, vertical arrangement, and grid arrangement, and can be determined based on factors such as production efficiency, quality, and cost of the actual product.

[0082] It should be noted that welding grooves 103 may be provided on the plastic panel 500, and welding ribs 501 may be provided on the assembly surface. Considering that the same cover body 100 is adapted to different decorative panels, it is preferred to provide welding grooves 103 on the assembly surface.

[0083] To sum up, the present application realizes the coexistence of the fixing structures of the surface light source panel 200 and the glass panel 300 through the setting of the assembly groove 101 and the glue groove 102, and the air duct cover plate can adapt to the installation of the surface light source panel 200 and the glass panel 300 at the same time; at the same time, the versatility of the air duct cover plate is improved by setting other fixing structures.

[0084] It should be understood that although this specification is described according to embodiments, not every embodiment contains only one independent technical solution. This narrative style of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0085] The series of detailed descriptions listed above are only specific descriptions of the feasible embodiments of the present application and are not intended to limit the scope of protection of the present application. Any equivalent embodiments or changes that do not deviate from the technical spirit of the present application should be included in the scope of protection of the present application.
