[0043] The present disclosure provides a surface light source 200 installation assembly for a refrigeration device, such as Figures 1 to 12 As shown, the surface light source 200 installation assembly for refrigeration equipment includes a cover plate 100 and a surface light source 200. The cover plate 100 is used to cover the air duct of the refrigeration equipment. The cover plate 100 is provided with an avoidance through hole 110, and the rear wall surface of the cover plate 100 is provided with a connecting portion 130. The surface light source 200 is arranged on the front wall surface of the cover plate 100, and the surface light source 200 is provided with a connecting matching portion 240 on the wall surface facing the cover plate 100. The connecting matching portion 240 passes through the avoidance through hole 110 and is detachably connected to the connecting portion 130.

[0044] The surface light source 200 installation assembly for refrigeration equipment provided by the embodiment of the present disclosure realizes a detachable connection between the connection portion 130 and the connection matching portion 240 by setting a connection portion 130 on the rear wall surface of the cover plate 100 and a connection matching portion 240 on the surface light source 200 facing the wall surface of the cover plate 100, so that the installation and removal of the surface light source 200 become simpler and faster. When cleaning or maintenance is required, the user or staff can easily remove the surface light source 200 from the cover plate 100 without using professional tools or performing complicated disassembly steps, saving time and improving work efficiency.

[0045] In addition, the cover plate 100 is provided with an avoidance through hole 110, and the connection fitting part 240 passes through the avoidance through hole 110 and is detachably connected to the connection part 130 on the rear wall of the cover plate 100, that is, the connection fitting part 240 is connected to the connection fitting part 240 at the rear side of the cover plate 100. In this way, the connection structure is not arranged at the side wall position of the surface light source 200 and the cover plate 100, so that the surface light source 200 and the cover plate 100 can be more tightly and flatly attached to the inner wall surface of the refrigeration equipment during installation, which not only reduces the gap that may be generated during the installation process, but also enhances the sealing and stability of the overall structure during use, and improves the convenience of installation of the surface light source 200 installation component and the overall fit.

[0046] In this embodiment, the cover plate 100 is used to cover the air duct of the refrigeration equipment, and the cover plate 100 is an air duct cover plate 100. The connecting and matching portion 240 of the surface light source 200 is connected to the connecting portion 130 of the cover plate 100. In this way, the cover plate 100 can not only cover the air duct of the refrigeration equipment, but also be used to install the surface light source 200, which can improve the utilization rate of the cover plate 100, reduce the number of components of the surface light source 200 installation assembly for the refrigeration equipment, and reduce the production cost of the refrigeration equipment.

[0047] The surface light source 200 is disposed on the front wall surface of the cover plate 100 , that is, the surface light source 200 is disposed on a side of the cover plate 100 facing the storage space of the refrigeration device.

[0048] In some optional embodiments, such as Figures 2 to 8As shown, the avoidance through hole 110 is located at the edge of the front wall of the cover plate 100, and the surface light source 200 includes a light source body 210 and a mounting frame 220. The mounting frame 220 is buckled at one or more ends of the light source body 210 to limit and fix the light source body 210. The wall of the mounting frame 220 facing the cover plate 100 is provided with one or more connecting and matching parts 240, and the number of the connecting parts 130 and the avoidance through hole 110 is the same as the number of the connecting and matching parts 240 and corresponds one to one.

[0049] In the embodiment of the present disclosure, the avoidance through hole 110 is arranged on the edge of the front wall of the cover plate 100, providing space for the installation of the surface light source 200, and the connecting and matching part 240 of the surface light source 200 is also correspondingly arranged on the edge of the surface light source 200, so that the surface light source 200 can fit more closely on the cover plate 100 during assembly, reducing unnecessary space and gaps that may be generated during the assembly process.

[0050] like Figures 1 to 3 and Fig.10 As shown, the surface light source 200 includes a light source body 210 and a mounting frame 220, wherein the mounting frame 220 is buckled at one or more ends of the light source body 210, the mounting frame 220 is provided with a connecting and matching portion 240, the mounting frame 220 is detachably connected to the cover plate 100, and the mounting frame 220 fixes the light source body 210. When the mounting frame 220 is buckled at multiple ends of the light source body 210, the stability and reliability of fixing the light source body 210 can be improved.

[0051] The number of connecting parts 130 is the same as the number of connecting matching parts 240 and corresponds one to one, and the number of avoidance through holes 110 is the same as the number of connecting matching parts 240 and corresponds one to one, so that each connecting matching part 240 can pass through the corresponding avoidance through hole 110 to connect with the corresponding connecting part 130, so as to improve the stability when the surface light source 200 is connected to the cover plate 100.

[0052] For example, Figure 1 and Fig.10 As shown, the mounting frame 220 includes a first mounting frame 221, a second mounting frame 222 and a third mounting frame 223 which are connected in sequence. The first mounting frame 221 and the third mounting frame 223 are respectively buckled on the ends of the light source body 210 which are arranged opposite to each other laterally, and the second mounting frame 222 is buckled on the upper end of the light source body 210.

[0053] In this embodiment, the mounting frame 220 includes a first mounting frame 221, a second mounting frame 222 and a third mounting frame 223 which are connected in sequence. For example, when the surface light source 200 is vertically arranged on the cover plate 100, the first mounting frame 221 and the third mounting frame 223 are respectively buckled on the ends of the light source body 210 which are arranged opposite to each other in the horizontal direction, that is, the first mounting frame 221 and the third mounting frame 223 are respectively buckled on the left end and the right end of the light source body 210, and the second mounting frame 222 is buckled on the upper end of the light source body 210. In this way, the first mounting frame 221, the second mounting frame 222 and the third mounting frame 223 respectively fix the three ends of the light source body 210, thereby improving the stability and reliability of the installation of the light source body 210.

[0054] Furthermore, the cover plate 100 is also provided with a mounting groove, the opening of which faces the surface light source 200, the lower end of the surface light source 200 is arranged in the mounting groove, and the bottom wall of the mounting groove is provided with a drain port for draining condensed water in the mounting groove.

[0055] With this optional embodiment, the lower end of the surface light source 200 is disposed in the mounting groove, and the mounting groove can support the surface light source 200, thereby improving the stability and reliability of the surface light source 200. Exemplarily, when the mounting frame 220 includes a first mounting frame 221, a second mounting frame 222, and a third mounting frame 223, the lower ends of the first mounting frame 221, the third mounting frame 223, and the light source body 210 are all disposed in the mounting groove.

[0056] The condensed water condensed on the surface light source 200 flows into the installation groove under the action of gravity, and the installation groove can collect the condensed water. A drainage port is provided on the bottom wall of the installation groove, and the condensed water can be discharged through the drainage port to reduce the accumulation of condensed water in the installation groove, reduce the occurrence of the lower end of the surface light source 200 being soaked, and improve the service life of the surface light source 200. In addition, the condensed water is discharged in time through the drainage port, which reduces the breeding of bacteria and mold and improves the safety of the use of the refrigeration equipment.

[0057] In some optional embodiments, such as Figure 6 As shown, the installation assembly of the surface light source 200 for refrigeration equipment also includes a duct foam 300 , which is connected to the rear wall of the cover plate 100 , and the avoidance through hole 110 and the connection part 130 are exposed outside the duct foam 300 .

[0058] In this embodiment, the air duct foam 300 is connected to the rear wall of the cover plate 100, and the air duct foam 300 and the cover plate 100 can enclose a cooling air duct to guide the flow of cold air. In addition, the air duct foam 300 can insulate the cold air in the cooling air duct, reduce the external heat transferred to the cooling air duct, reduce the loss of cold, improve the energy efficiency of the refrigeration equipment, and reduce energy consumption.

[0059] The avoidance through hole 110 and the connection part 130 are exposed outside the air duct foam 300, that is, the air duct foam 300 does not cover the avoidance through hole 110, the connection part 130 and the connection matching part 240. In this way, when the surface light source 200 is disassembled, the air duct foam 300 does not hinder the installation and disassembly of the surface light source 200, and the air duct foam 300 does not need to be disassembled, which simplifies the operation process and reduces the maintenance cost.

[0060] In some optional embodiments, such as Figures 2 to 8 As shown, the rear wall surface of the cover plate 100 is convexly provided with a first connection protrusion 120, the first connection protrusion 120 is provided with a first connection hole 131, and the connection portion 130 includes the first connection hole 131.

[0061] In this embodiment, the wall surface of the mounting frame 220 facing the cover plate 100 is preset with a second connection protrusion 230, and the second connection protrusion 230 can pass through the avoidance through hole 110, so that the second connection hole 241 can be located at the rear side of the cover plate 100, and the second connection hole 241 is connected to the first connection hole 131 at the rear side of the cover plate 100. The first connection hole 131 and the second connection hole 241 are detachably connected by the fastener 400, which not only improves the connection strength between the surface light source 200 and the cover plate 100, but also simplifies the disassembly and replacement steps of the surface light source 200. When the surface light source 200 needs to be maintained or replaced, the user or maintenance personnel only needs to simply loosen the fastener 400 to remove the surface light source 200 from the cover plate 100, which greatly simplifies the maintenance process and reduces the maintenance cost.

[0062] Furthermore, if Figures 10 to 12 As shown, the fastener 400 includes a connecting portion 130, and the connecting portion 130 is disposed in the first connecting hole 131 and the second connecting hole 241. Along the extending direction of the installation frame 220, the extending diameter of the first connecting hole 131 is larger than the diameter of the connecting portion 130.

[0065] In this embodiment, Fig.11 and Fig.12 As shown, along the extension direction of the installation frame 220, the extension diameter of the first connection hole 131 is larger than the diameter of the connection portion 130, so that during the installation process, the surface light source 200 can move relative to the cover plate 100 along the extension direction of the installation frame 220, and the installation position of the surface light source 200 can be fine-tuned, making the installation of the surface light source 200 more flexible and accurate. It also reduces the difficulty of aligning the surface light source 200 during installation and improves installation efficiency.

[0066] Optionally, the second connecting protrusion 230 is located on a side of the first connecting protrusion 120 away from the middle of the cover plate 100 .

[0067] In this embodiment, the second connection protrusion 230 is located on the side of the first connection protrusion 120 away from the middle of the cover plate 100, that is, the second connection protrusion 230 is located outside the first connection protrusion 120, and the second connection hole 241 is located outside the first connection hole 131.

Optionally, the fastener 400 further includes a pressing portion, which is connected to the connection portion 130, and the pressing portion is used to press the second connection protrusion 230 on the first connection protrusion 120. The first installation frame 221 and the third installation frame 223 are vertically extended installation frames 220, and the pressing portion presses the second connection protrusion 230 on the first connection protrusion 120, and the second connection protrusion 230 abuts against the wall surface opposite to the first connection protrusion 120, and the first connection protrusion 120 can provide friction to the second connection protrusion 230 to position the surface light source 200, reduce the occurrence of displacement of the surface light source 200 after installation, and improve the stability and reliability of the installation of the surface light source 200.

[0069] Furthermore, if Figure 5 and Figure 8As shown, the first connecting protrusion 120 is also provided with a mounting through hole 140, and the mounting through hole 140 is connected to the avoidance through hole 110, and the mounting through hole 140 divides the first connecting hole 131 into a first sub-connecting hole and a second sub-connecting hole, and the second connecting protrusion 230 is located in the mounting through hole 140, and the first sub-connecting hole is located on the side of the second sub-connecting hole away from the middle of the cover plate 100, and the fastener 400 is sequentially arranged in the first sub-connecting hole, the second connecting hole 241 and the second sub-connecting hole.

Alternatively, the fastener 400 passes through the first sub-connection hole, the second connection hole 241 and the second sub-connection hole and is threadedly connected with the nut.

[0071] For example, the second connection protrusion 230 of the second installation frame 222 passes through the avoidance through hole 110 and is located in the corresponding installation through hole 140 .

[0072] In some optional embodiments, such as Fig. 9 As shown, the surface light source 200 further includes an integrated wiring harness 250 and a first connection terminal 260 , and one end of the integrated wiring harness 250 is connected to the light source body 210 .
