Preferably, the groove depth of the adhesive groove 102 is 0.2-0.4 mm.

[0038] Another of the fixing structures is a welding groove 103 provided on the mounting surface. The welding groove 103 is located between the mounting groove 101 and the adhesive groove 102. The welding groove 103 extends along the height direction of the mounting surface. The welding groove 103 is adapted for an installation of a decorative panel with a welding rib 501.

[0039] The cover body 100 and / or the decorative panel is provided with a shielding member. The shielding member is configured to shield an assembly gap between the cover body 100 and the decorative panel.

[0040] In a specific embodiment, the shielding member is a blocking rib 104 extending from the mounting surface toward the decorative panel, and the blocking rib 104 is located on an outer side of the mounting groove 101.

[0041] A bottom of the cover body 100 is provided with a positioning groove 106. The positioning groove 106 is located on the mounting surface, and the positioning groove 106 extends along a horizontal direction. When mounting the decorative panel, a bottom end of the decorative panel is inserted into the positioning groove 106, thereby playing a role of pre-assembly positioning.

[0042] Referring to FIG. 1 to FIG. 8, in a specific embodiment, the mounting groove 101 is configured to mount a surface light source panel 200. The surface light source panel 200 comprises a top trim strip located at a top of the surface light source panel 200, and a lateral trim strip 201 on two sides along the width direction. The top trim strip is located between the two lateral trim strips 201. The top trim strip and the lateral trim strip 201 are wrapped on an edge of the surface light source panel 200. The surface light source panel 200 is fixed in the mounting groove 101 through the top trim strip and the lateral trim strip 201.

[0043] Correspondingly, the mounting groove 101 is located at the top of the mounting surface and on the two sides along the width direction. The mounting groove 101 located on the two sides of the mounting surface along the width direction extends along the height direction of the mounting surface, and the mounting groove 101 located on the two sides is in communication with the mounting groove 101 located at the top, thereby forming an integral body for mounting the surface light source panel 200. The top trim strip is located in the mounting groove 101 at the top of the mounting surface. The lateral trim strip 201 is located in the mounting groove 101 on the two sides of the mounting surface.

[0044] The top trim strip may adopt an existing ordinary trim strip. The lateral trim strip 201 serves as the shielding member to shield an assembly gap between the surface light source panel 200 and the mounting surface, and at the same time shields the blocking rib 104 located on the mounting surface.

[0045] The lateral trim strip 201 comprises a first connecting portion 201a, a second connecting portion 201b and a third connecting portion 201c located between the first connecting portion 201a and the second connecting portion 201b. The second connecting portion 201b is located in the mounting groove 101. The surface light source panel 200 is snap-fitted between the first connecting portion 201a and the second connecting portion 201b.

[0046] The first connecting portion 201a and the second connecting portion 201b are parallel to each other. The third connecting portion 201c is connected to same side ends of the first connecting portion 201a and the second connecting portion 201b, and a width of the first connecting portion 201a is smaller than a width of the second connecting portion 201b. The second connecting portion 201b is located in the mounting groove 101, and a width of the second connecting portion 201b is adapted to the mounting groove 101. The width of the first connecting portion 201a may be adaptively adjusted according to needs.

[0047] 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.

[0048] A mounting hole 101a is provided at intervals in the mounting groove 101. The cover body 100 further comprises a first fixing hole 105 located at a side of the mounting hole 101a.

[0049] The lateral trim strip 201 further comprises a fixing portion 201d extending from the second connecting portion 201b toward the mounting surface, and the fixing portion 201d corresponds to the mounting hole 101a one by one. The fixing portion 201d is perpendicular to the second connecting portion 201b. A second fixing hole 201e is opened on the fixing portion 201d. Preferably, a distance from the fixing portion 201d to an end of the second connecting portion 201b away from the third connecting portion 201c is 6 mm.

[0050] A thickness of the third connecting portion 201c gradually increases in a direction from the first connecting portion 201a to the second connecting portion 201b. When the surface light source panel 200 is fixed in the mounting groove 101 through the lateral trim strip 201, a user can only see the third connecting portion 201c from a side of the air duct cover. A shielding inclined surface provided by the third connecting portion 201c shields a side edge of the surface light source panel 200 and an assembly interface between the surface light source panel 200 and the mounting surface, making the air duct cover as a whole more beautiful.

[0051] A notch 201f is formed at a connection between the second connecting portion 201b and the third connecting portion 201c. When the surface light source panel 200 is fixed in the mounting groove 101 through the lateral trim strip 201, the blocking rib 104 is located in the notch 201f, thereby achieving a shielding of the blocking rib 104.

[0052] When mounting the surface light source panel 200, the top trim strip is placed in the mounting groove 101 at the top of the mounting surface, and the lateral trim strip 201 is placed in the mounting groove 101 on the two sides of the mounting surface. The fixing portion 201d of the lateral trim strip 201 passes through the mounting hole 101a in the mounting groove 101, the second fixing hole 201e on the fixing portion 201d is coaxially aligned with the first fixing hole 105, and finally a fixing of the surface light source panel 200 is achieved through a fixing member such as a screw passing through the first fixing hole 105 and the second fixing hole 201e.

[0053] Referring to FIG. 1, FIG. 2, and FIG. 9 to FIG. 11, the adhesive groove 102 is configured to mount the glass panel 300. The double-sided tape is provided or the hot melt adhesive is injected 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 to the mounting surface, and an adhesive fixing of the glass panel 300 is achieved through the double-sided tape or the hot melt adhesive.

[0054] An overflow groove is also provided on an inner side of the adhesive groove 102. When the hot melt adhesive is injected into the adhesive groove 102 for the adhesive fixing of the glass panel 300, the overflow groove is configured to prevent the hot melt adhesive from flowing randomly when being pressed, which in turn affects a fixing effect.

[0055] When the glass panel 300 is pressed and fixed on the mounting surface, due to an existence of the mounting groove 101, a larger side gap will exist between the glass panel 300 and the mounting surface. Thus, by providing the blocking rib 104 to shield the gap between the glass panel 300 and the mounting surface, that is, the mounting groove 101, the air duct cover as a whole is made more beautiful. Preferably, the blocking rib 104 is provided perpendicular to the mounting surface.

[0056] Certainly, the blocking rib 104 may also be provided on the glass panel 300. The blocking rib 104 extends from the glass panel 300 toward the mounting surface, which can also play a role of shielding the gap between the glass panel 300 and the mounting surface.

[0057] Since a fixing structure of the surface light source panel 200 is a screw, and a fixing structure of the glass panel 300 is an adhesive, fixing structures on two sides along the width direction of an existing air duct cover cannot coexist. The air duct cover provided by the present application, by providing the mounting groove 101 and the adhesive groove 102 in a staggered manner on the mounting surface, makes the adhesive groove 102 located on the inner side of the mounting groove 101, thereby achieving a coexistence of the fixing structures on the two sides.

[0058] For the surface light source panel 200 and the glass panel 300, a thickness difference exists between the two, which causes a difference in interfaces at a top and a bottom of the air duct cover. And the surface light source panel 200 is provided with the trim strip 201, which further increases the thickness difference between the surface light source panel 200 and the glass panel 300 and affects the coexistence of the fixing structures.

[0059] The air duct cover provided by the present application, by providing the mounting groove 101 on the mounting surface for accommodating the trim strip 201, and increasing the groove depth of the mounting groove 101, creates a depth difference between the mounting groove 101 and the adhesive groove 102, thereby unifying as much as possible assembly dimensions of the surface light source panel 200 and the glass panel 300 in a thickness direction, 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 mount the surface light source panel 200 and the glass panel 300, to meet different needs.

[0060] Referring to FIG. 1, FIG. 2 and FIG. 12, the adhesive groove 102 is configured to mount a metal panel 400. The double-sided tape is provided or the hot melt adhesive is injected in the adhesive groove 102, a bottom end of the metal panel 400 is inserted into the positioning groove 106, and the metal panel 400 is pressed to the mounting surface, and an adhesive fixing of the metal panel 400 is achieved through the double-sided tape or the hot melt adhesive. The blocking rib 104 shields a gap between the metal panel 400 and the mounting surface, that is, the mounting groove 101, making the air duct cover as a whole more beautiful.

[0061] In some embodiments, the metal panel 400 comprises a fixing tab 401 provided at intervals at two ends and a top of the metal panel 400 along the width direction, and the fixing tab 401 extends toward the cover body 100.

[0062] Specifically, the fixing tab 401 is provided perpendicular to the metal panel 400. The fixing tab 401 comprises a bent portion and a fixing portion, the fixing portion is connected to the metal panel 400 through the bent portion, and a width of the bent portion is smaller than a width of the fixing portion.

[0063] When the metal panel 400 is adhesively bonded to the mounting surface, the fixing tab 401 is bent toward a side of the cover body 100, the bent portion is bent by 90°, the fixing portion is in close contact with the cover body 100, so that the cover body 100 is located between the metal panel 400 and the fixing portion, thereby achieving a reinforced fixing of the metal panel 400. Certainly, in this embodiment, the fixing of the metal panel 400 can also be achieved solely through the fixing tab 401.

[0064] Referring to FIG. 1, FIG. 2 and FIG. 13, the welding groove 103 is configured to fix a plastic panel 500. A surface of the plastic panel 500 corresponding to the mounting surface is provided with a welding rib 501, and the mounting surface is provided with a welding groove 103 corresponding to the welding rib 501.

[0065] When mounting the plastic panel 500, a bottom end of the plastic panel 500 is inserted into the positioning groove 106, the plastic panel 500 is fitted to the mounting surface and the welding rib 501 is aligned with the welding groove 103, and finally the plastic panel 500 is fixed by an ultrasonic welding method. The blocking rib 104 shields a gap between the plastic panel 500 and the mounting surface, that is, the mounting groove 101, making the air duct cover as a whole more beautiful.

[0066] An arrangement manner of the welding rib 501 and the welding groove 103 includes but is not limited to a transverse arrangement, a vertical arrangement and a grid arrangement. The arrangement manner may be comprehensively determined according to factors such as production efficiency, quality, and cost of an actual product.

[0067] It needs to be particularly noted that the welding groove 103 may also be provided on the plastic panel 500, and the welding rib 501 may be provided on the mounting surface. Considering that the cover body 100 is adapted to different decorative panels, it is preferable to provide the welding groove 103 on the mounting surface.

[0068] In summary, the present application achieves the coexistence of the fixing structures of the surface light source panel 200 and the glass panel 300 through the provision of the mounting groove 101 and the adhesive groove 102, so that the air duct cover can simultaneously adapt to the installation of the surface light source panel 200 and the glass panel 300; at the same time, the universality of the air duct cover is improved by providing other fixing structures.

[0069] It should be understood that, although this specification is described according to embodiments, not every embodiment only contains one independent technical solution. This narrative manner of the specification is merely for clarity. A person skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment may also be appropriately combined to form other embodiments that can be understood by a person skilled in the art.
