It should be understood that those skilled in the art will recognize that this application can be made without using these specific details. In other instances, well-known structures and processes are not described in detail to avoid obscuring the description of this application with unnecessary detail. Therefore, this application is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0030] On the one hand, such as Figures 1 to 7As shown, this application embodiment provides a side panel assembly, including a decorative panel 2 and a side panel body 1. The side panel body 1 is used to install on both ends of the middle frame 3 of a refrigeration device. The decorative panel 2 is disposed on the side of the side panel body 1 away from the middle frame 3. A first snap-fit ​​structure 11 is provided on the side of the side panel body 1 away from the middle frame 3. The side panel body 1 is provided with an installation opening. The decorative panel 2 is used to cover the installation opening. A second snap-fit ​​structure 21 is provided on the side of the decorative panel 2 facing the side panel body 1. The decorative panel 2 can rotatably engage the first snap-fit ​​structure 11 with the second snap-fit ​​structure 21 and can rotatably separate the first snap-fit ​​structure 11 from the second snap-fit ​​structure 21. When the first snap-fit ​​structure 11 is engaged with the second snap-fit ​​structure 21, the decorative panel 2 and the side panel body 1 are fixedly connected.

[0031] The refrigeration equipment can be an indoor air conditioner unit, a cabinet air conditioner unit, or an air conditioning fan, etc. The existing side panel assembly has a complex connection structure with the frame 3 of the refrigeration equipment, which not only makes the disassembly and assembly of the side panel assembly difficult, but also results in a high production cost.

[0032] In this embodiment, the side panel body 1 is provided with an installation port, through which the internal structure of the refrigeration equipment can be inspected for maintenance. A decorative panel 2 is provided at the installation port. A first snap-fit ​​structure 11 is provided on the side of the side panel body 1 facing the decorative panel 2. A second snap-fit ​​structure 21 is provided on the decorative panel 2 corresponding to the first snap-fit ​​structure 11. The decorative panel 2 is rotatably disposed at the installation port. By rotating the decorative panel 2, the first snap-fit ​​structure 11 and the second snap-fit ​​structure 21 can be snapped together to complete the installation of the decorative panel 2. Rotating the decorative panel 2 in the opposite direction can remove the decorative panel 2. This arrangement simplifies the installation and removal of the decorative panel 2, thereby improving the efficiency of the installation and removal of the decorative panel 2. Both ends of the refrigeration equipment use side panel assemblies with the same structure, which can ensure that the installation and removal of the decorative panels 2 on both sides of the refrigeration equipment is simple.

[0033] In some embodiments, one of the first snap-fit ​​structure 11 and the second snap-fit ​​structure 21 is an arc-shaped groove, and the other is a rotating buckle, which is used to insert into and snap into the arc-shaped groove.

[0034] Specifically, when the decorative panel 2 is placed over the installation opening, the rotating buckle is inserted into the arc-shaped groove. By rotating the decorative panel 2, when the rotating buckle rotates to a certain position, it can engage with the arc-shaped groove. This design simplifies the structure of both the rotating buckle and the arc-shaped groove, and the connection method is simple and convenient, improving the efficiency of assembling and disassembling the decorative panel 2. In other embodiments, both the first engaging structure 11 and the second engaging structure 21 are elastic buckles with locking teeth that engage with each other.

[0035] In some embodiments, the decorative panel 2 is provided with a rotating buckle, and an arc-shaped groove is provided in the side panel body 1, so that the decorative panel 2 is rotatably snapped into the side panel body 1.

[0036] Specifically, a rotating buckle protrudes from the decorative panel 2, and an arc-shaped groove is recessed into the side panel body 1. This arrangement facilitates the forming of the rotating buckle and the arc-shaped groove. The decorative panel 2 and the rotating buckle are integrally formed, making production more convenient and enhancing the connection stability and overall structural strength of the rotating buckle and the decorative panel 2. In some other embodiments, the side panel body 1 is provided with a rotating buckle, and the arc-shaped groove is provided in the decorative panel 2.

[0037] In some embodiments, one end of the arc groove is provided with an elastic boss 12, and the decorative plate 2 is provided with a locking rib 22 spaced apart from the rotating buckle. When the rotating buckle is engaged with one end of the arc groove, the elastic boss 12 at the other end of the arc groove deforms to abut against the locking rib 22.

[0038] Specifically, an elastic boss 12 is provided at one end of the arc-shaped groove, and a locking rib 22 is also provided on the decorative panel 2. When the rotating buckle rotates a certain distance, the rotating buckle is engaged with the other end of the arc-shaped groove, and the end of the locking rib 22 can abut against the elastic boss 12. At this time, the elastic boss 12 undergoes a certain elastic deformation, and the reverse force can press the elastic boss 12 itself onto the locking rib 22. This setting can further improve the installation stability of the decorative panel 2, and the decorative panel 2 is not easy to detach from the side panel body 1 when installed.

[0039] In some embodiments, multiple arc-shaped grooves are provided, which are concentrically arranged and evenly spaced in sequence. The elastic boss 12, the rotating buckle and the locking rib 22 are provided in multiple corresponding arc-shaped grooves.

[0040] Specifically, the two ends of the side panel body 1 are provided with multiple arc-shaped grooves. The multiple arc-shaped grooves on the same side are concentric and spaced apart from each other. Correspondingly, the decorative panel 2 is provided with multiple locking ribs 22 and rotating buckles. The multiple rotating buckles are evenly spaced along the circumference, and the locking ribs 22 are evenly spaced along the circumference. In this way, when the decorative panel 2 is rotated and installed, all the rotating buckles and locking ribs 22 can be engaged at the same time. With this setting, multiple sets of connection structures are provided between the decorative panel 2 and the side panel body 1, which can further improve the connection stability between the decorative panel 2 and the side panel body 1.

[0041] In some embodiments, the side panel body 1 is provided with a third snap-fit ​​structure 13 and a first insertion structure 14 on the side facing the middle frame 3, and the mounting position is provided with a second insertion structure 32 and a fourth snap-fit ​​structure 31 on the side panel body 1. The side panel body 1 can slide such that the third snap-fit ​​structure 13 snaps into the fourth snap-fit ​​structure 31 and the first insertion structure 14 inserts into the second insertion structure 32, so that the side panel body 1 snaps into the middle frame 3.

[0042] Specifically, the side panel body 1 is also detachably connected to the middle frame 3 of the refrigeration equipment. A third snap-fit ​​structure 13 and a first insertion structure 14 are provided on one side of the side panel body 1, and a fourth snap-fit ​​structure 31 and a second insertion structure 32 are provided on the middle frame 3. First, the side panel body 1 is inserted obliquely into the middle frame 3, so that the first insertion structure 14 and the second insertion structure 32 interlock. Then, the third snap-fit ​​structure 13 and the fourth snap-fit ​​structure 31 interlock, thereby completing the installation of the side panel body 1. This design simplifies the assembly and disassembly of the side panel body 1 and eliminates the need for bolts or screws for fixing, facilitating assembly and disassembly and improving efficiency. In other embodiments, the side panel body 1 has a through hole for screws to pass through, and the screws are screwed into the middle frame 3 to fix the side panel body 1.

[0043] In some embodiments, the first plug-in structure 14 is a plug-in buckle, and the second plug-in structure 32 is a plug-in groove. The plug-in groove is recessed at the edge of the middle frame 3 and is arc-shaped. The plug-in buckle protrudes from the side plate body 1. There are multiple plug-in buckles, and the multiple plug-in buckles are distributed at intervals along the edge of the side plate body 1.

[0044] Specifically, the snap-fit ​​fastener is a plate-shaped structure, with a snap-fit ​​groove located on the inner edge of the middle frame 3. The shape of the snap-fit ​​fastener is adapted to the snap-fit ​​groove. The snap-fit ​​fastener protrudes from the side edge of the side panel body 1 and is aligned with the extension direction of the side panel body 1. Multiple snap-fit ​​fasteners are evenly spaced along the edge of the side panel body 1, forming an arc-shaped plate-shaped structure. The arc-shaped plate-shaped structure is inserted into the snap-fit ​​groove to achieve the insertion of the side panel body 1. This arrangement increases the insertion stability of the side panel body 1. In other embodiments, the first insertion structure 14 is a snap-fit ​​groove, and the second insertion structure 32 is a snap-fit ​​fastener.

[0045] In some embodiments, the third snap-fit ​​structure 13 is a snap-fit, and the fourth snap-fit ​​structure 31 is a snap-fit ​​hole. The snap-fit ​​protrudes from the side of the side panel body 1 facing the middle frame 3, and there are multiple snap-fits. The multiple snap-fits are spaced apart from each other, and the snap-fit ​​holes are corresponding to the snap-fits one by one.

[0046] Specifically, the buckle is an elastic buckle component. By engaging the buckle with the buckle hole, the side panel body 1 and the middle frame 3 are connected. When one end of the side panel body 1 is inserted into the middle frame 3, that end of the side panel body 1 is already limited. Then, the buckle is engaged with the buckle hole to limit the other end of the side panel body 1, thereby fixing the side panel body 1. This design makes both the third and fourth buckle structures 13 simple, and the connection between them convenient and efficient, thus optimizing the connection structure and assembly / disassembly efficiency of the side panel body 1. In some other embodiments, the third buckle structure 13 is a buckle hole, and the fourth buckle structure 31 is a buckle.

[0047] In some embodiments, multiple snap-fit ​​holes are connected in sequence to form an enclosed space. A limiting hole 3315 is provided in the enclosed space. A limiting boss 18 is protruding from the surface of the side plate body 1. The limiting boss 18 is used to be inserted into the limiting hole 3315 to restrict the movement of the side plate body 1.

[0048] Specifically, the enclosed space formed by the multiple snap-fit ​​holes is rectangular. There are four snap-fit ​​holes, distributed at the four corners of the rectangle. A limiting hole 3315 is located at the center of the enclosed space. A rectangular limiting boss 18 is provided on the side panel body 1 corresponding to the limiting hole 3315. The limiting boss 18 is inserted into the limiting hole 3315 to restrict the movement of the side panel body 1 in the front-back direction. The limiting hole 3315 is rectangular, and its length is greater than the length of the limiting boss 18. This arrangement further increases the installation stability of the side panel body 1. In other embodiments, the side panel body 1 has an elastic protrusion, and the middle frame 3 has a limiting circular hole. The elastic protrusion is used to insert into the limiting circular hole.

[0049] In some embodiments, at least one snap hole is provided with an anti-collision rib 16 protruding at the edge of the snap hole, the anti-collision rib 16 extends along the edge of the snap hole, and each snap hole is provided with a support rib 17 at the edge, the support rib 17 extends along the edge of the snap hole in a ring shape.

[0050] Specifically, strip-shaped anti-collision ribs 16 are provided at the upper and lower ends of one of the buckle holes. The width of the anti-collision ribs 16 is greater than or equal to the width of the buckle hole. Support ribs 17 are provided at the edge of each buckle hole. The support ribs 17 extend in a ring shape along the periphery of the buckle hole. The anti-collision ribs 16 and support ribs 17 are respectively located on both sides of the middle frame 3. This arrangement strengthens the structural strength of the buckle hole through the support ribs 17. Since the overall space of the refrigeration equipment is limited, the buckle is too close to the electrical control box, and the buckle is easy to break during drop tests. Therefore, anti-collision ribs 16 are added to protect the buckle.

[0051] On the other hand, embodiments of this application provide a refrigeration device, including the side panel assembly as described above.

[0052] Specifically, the refrigeration equipment is an indoor air conditioning unit, and there are two side panel assemblies, which are installed at the left and right ends of the middle frame 3 of the refrigeration equipment, respectively.

[0053] The side panel assembly and cooling device provided in the embodiments of this application have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
