[0084] In order to make the purpose, technical solutions and advantages of this application clearer, the following part will further describe the embodiments of this application in detail with reference to the accompanying drawings.

[0085] When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application, as detailed in the appended claims.

[0086] In the description of this application, it should be understood that the terms "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

"And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the previous and subsequent associated objects are in an "or" relationship.

[0087] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application belongs. The terms used in this specification are for the purpose of describing specific embodiments only and are not intended to limit this application. The term "and / or" as used herein includes any and all combinations of one or more of the relevant listed items.

[0088] The indoor unit includes a housing and a panel structure, which is mounted on the housing and also serves to secure the controller. However, conventional panel structures typically include a panel connected to a mounting bracket, with the controller secured to the panel structure by mounting on the mounting bracket. However, securing the controller solely through the mounting bracket leaves limited area for securing the controller, making it susceptible to disconnection from the panel structure and possible drop of the controller due to poor connection stability.

[0089] To solve the above problems, please refer to Figure 1. On the one hand, the present application proposes a HVAC system, which includes but is not limited to air conditioners, multi-split units, heat pumps, water heaters, swimming pool machines and other equipment. Taking a HVAC device whose heating medium is refrigerant and whose heating object is water as an example, the HVAC system of the HVAC device may include an indoor unit for heating water located indoors and an outdoor unit that can be located outdoors and performs heat exchange with the external environment, and the indoor unit is connected to the outdoor unit. Figure 1 shows a partial structure of the indoor unit 300. The indoor unit 300 may include a water circulation path and a refrigerant pipe. Refrigerant flows in the refrigerant pipe. The indoor unit 300 heats the water by exchanging heat between the refrigerant in the refrigerant pipe and the water in the water circulation path to output water at a set temperature.

[0090] Specifically, the indoor unit 300 includes a housing with a panel structure 100. As will be appreciated, the indoor unit also includes components such as refrigerant pipes (not shown), a controller 310, an electric heater (not shown), an electrical control box (not shown), a heat exchanger (not shown), a water pump (not shown), and an energy storage tank (not shown). The controller is mounted on the housing panel structure 100. Other components, such as the refrigerant pipes, electric heater, heat exchanger, and water pump, are located within the housing. The heat exchanger, energy storage tank, and water pump are connected by water pipes to form a water circulation path. The heat exchanger has two inlets and two outlets. One set of interconnected inlets and outlets allows the refrigerant pipes to pass through, while the other set of interconnected inlets and outlets allows the water medium to pass through. When the water medium flows through the heat exchanger, the refrigerant pipes within the heat exchanger come into contact with the water, and the refrigerant within the pipes dissipates heat, thereby heating the water in the heat exchanger. The water pump provides the power for the water circulation. An electric heating device can be installed between the heat exchanger and the energy storage tank. Water heated by the heat exchanger is reheated in the electric heating device and then flows through a water pipe into the energy storage tank. This assists the heat exchanger in providing heat in low-temperature environments, thereby raising the water temperature in the energy storage tank, achieving a better heating effect and improving the unit's energy efficiency. The energy storage tank is used to store or transport water at a set temperature to an external device, such as a floor heating pipe or a user's domestic water pipe, thereby meeting the user's heating needs.

[0091] The outdoor unit may include components such as an evaporator, a compressor, and an expansion valve. These components are connected in a circular fashion via refrigerant pipes. When the HVAC system is operating, the refrigerant in the evaporator absorbs heat from the air, transforming it from a low-temperature, low-pressure gas into a high-temperature, low-pressure gas. This high-temperature gas is then compressed by the compressor, turning it into a high-temperature, high-pressure liquid. This high-temperature, high-pressure liquid exchanges heat with water in the water circulation circuit through a heat exchanger, raising the water temperature and transforming the refrigerant into a low-temperature, high-pressure liquid. This low-temperature, high-pressure liquid then passes through the expansion valve and becomes a low-temperature, low-pressure gas, which then circulates back to the evaporator, completing the refrigerant cycle.

[0092] Referring to Figures 2 to 4 , in the embodiment of the present application, the indoor unit 300 forms a housing with an opening within the housing. The panel structure 100 covers the opening and is connected to the sidewalls of the housing that enclose the housing. A controller 310 is mounted on the panel structure 100, and refrigerant pipes, an electric heater, a heat exchanger, a water pump, and the like are housed within the housing. It is understood that the controller 310 can be electrically connected to an electrical control box, so that a user can operate the controller 310 to input relevant parameters. The controller 310 then transmits signals to the electrical control box, which in turn controls the heat exchanger, electric heater, and other components. For example, after the controller 310 inputs relevant temperature parameters, the electrical control box controls the specific operating mode of the heat exchanger or electric heater. Specifically, the controller 310 can include a display module and a key module. The display module can display relevant parameter information, while the key module can be operated by the user to input the required relevant parameters or select the desired relevant operating mode.

[0093] In order to avoid the controller 310 from being disconnected from the panel structure 100, please continue to refer to Figures 2 to 4. The panel structure 100 proposed in this application includes a panel assembly 11 and a decorative panel group 13, wherein the panel assembly 11 is connected to the side wall of the casing that surrounds the accommodating cavity to cover the opening of the accommodating cavity, and the decorative panel group 13 is connected to the panel assembly 11.

[0094] The panel assembly 11 includes a panel 111 and a mounting bracket 113. The panel 111 can be roughly square in shape, and the shape of the panel 111 is adapted to the shape of the opening. The material of the panel 111 can be metal, such as aluminum or stainless steel, etc., so as to have better structural strength and better corrosion resistance and oxidation resistance and other advantages. Of course, the material of the panel 111 can also be plastic material, so as to have advantages such as lighter overall weight. The embodiment of the present application does not limit this.

[0095] The mounting bracket 113 can be roughly rectangular in shape, and the material of the mounting bracket 113 can be metal, such as aluminum or stainless steel, etc., so as to have better structural strength and better corrosion resistance and oxidation resistance and other advantages. Of course, the material of the mounting bracket 113 can also be plastic material, so as to have advantages such as lighter overall weight, etc., and the embodiment of the present application does not limit this.

[0096] The decorative panel group 13 can be in a square shape, a circular shape or an irregular shape, etc. The decorative panel group 13 can be in the form of an acrylic panel or a paint panel, etc., with the advantages of high gloss, a smoother surface and a brighter color, etc. The present application does not impose any restrictions on this. It can be understood that the decorative panel group 13 is more aesthetically pleasing and has a better decorative effect than the panel assembly 11, thereby improving the overall aesthetics and texture of the panel structure 100. For example, the main structure of the decorative panel group 13 can be made of a black acrylic panel. In this way, while improving the overall appearance, the technological sense of the panel structure 100 can be improved.

[0097] Among them, at least one of the mounting bracket 113 and the decorative panel group 13 is connected to the panel 111 and is used to cooperate with clamping and fixing the controller 310. It is understandable that the mounting bracket 113 can be connected to the inner surface of the panel 111, and the decorative panel group 13 is connected to the mounting bracket 113, on this basis, to achieve the coordination of clamping and fixing the controller 310; the decorative panel group 13 can also be connected to the inner surface of the panel 111, and the mounting bracket 113 is connected to the decorative panel group 13, on this basis, to achieve the coordination of clamping and fixing the controller 310; or the mounting bracket 113 and the decorative panel group 13 can also be connected to the panel 111 separately, on this basis, to achieve the coordination of clamping and fixing the controller 310, and the embodiments of the present application are not limited to this.

[0098] Among them, on the basis of the connection between the mounting bracket 113 and the panel 111, the periphery of the mounting bracket 113 can be formed with a flange, and welded to the panel 111 through the flange, so that the connection area with the panel 111 can be increased by the flange, and the more fixed connection form of welding is adopted to achieve the stability of the connection between the mounting bracket 113 and the panel 111; of course, the mounting bracket 113 can also be connected to the panel 111 through connection forms such as snapping or bonding, and the embodiments of the present application are not limited to this.

[0099] In this way, the controller 310 is clamped and fixed by the cooperation of the mounting bracket 113 and the decorative panel group 13. Compared with the related art in which the controller 310 is fixed only by the mounting bracket, the clamping form of the embodiment of the present application can increase the connection area of ​​the panel structure 100 to the controller 310, and the wrapping fixation of the controller 310 can be increased by clamping. In this way, the fixing effect of the panel structure 100 on the controller 310 can be effectively improved, and the possibility of the controller 310 being separated from the panel structure 100 and falling can be reduced.

[0100] Please continue to refer to Figures 4 and 5. In some embodiments, the panel 111 is provided with an installation port 111a for installing the controller 310, wherein the installation bracket 113 and the decorative panel group 13 are respectively connected to the two opposite surfaces of the panel 111 along its thickness direction, so as to cooperate in clamping the controller 310 and fixing the controller 310 at the installation port 111a.

[0101] It can be understood that the decorative panel group 13 is connected to the outer surface of the panel 111, and the mounting bracket 113 is connected to the inner surface of the panel 111. In this way, the decorative panel group 13 can be located on the outside of the panel 111 to achieve a decorative effect, and when the controller 310 is fixed at the mounting port 111a, the panel 111 and the controller 310 can cooperate to cover the mounting bracket 113, further improving the aesthetics of the indoor unit 300.

[0102] Moreover, compared with the decorative panel group 13 being located on the inner side of the panel 111, which requires the panel 111 itself to be configured to reveal the transparent part of the controller 310, the entire panel 111 of this embodiment can be made of metal. In this way, the structure of the panel 111 can be simpler, and it can be manufactured through one-time processing, which is more convenient to manufacture.

[0103] Please refer to FIG. 4 to FIG. 6 . Further, the decorative plate assembly 13 is provided with a limiting groove 137 b for embedding the controller 310 . The groove wall of the limiting groove 137 b cooperates with the mounting bracket 113 to clamp and fix the controller 310 .

[0104] It can be understood that the limiting groove 137b can limit the outer edge of the controller 310. Therefore, the controller 310 and the limiting groove 137b will have multiple limiting surfaces, and the groove wall of the limiting groove 137b can limit the controller 310 in the direction from inside to outside, up and down, and left and right directions of the panel structure 100. Compared with the decorative panel group 13 that only limits the controller 310 through one surface, the controller 310 of the embodiment of the present application cooperates with multiple groove walls that form limiting grooves at different angles. Such a limiting clamping effect is obviously more stable than the limiting connection of one surface.

[0105] In other embodiments, the controller 310 may be clamped and fixed by directly cooperating with the mounting bracket 113 through the panel surface of the decorative panel group 13, and this embodiment of the present application does not limit this.

[0106] Please refer to Figure 6. In some structural forms, the decorative panel assembly 13 is provided with an exposed area corresponding to the installation opening 111a, and the limiting groove 137b is provided around the outside of the exposed area. The light emitted by the display module of the controller 310 can pass through the exposed area to the outside, so that the user can obtain the display information of the display module from the outside of the panel structure 100. In this way, based on the limiting groove 137b surrounding the outside of the exposed area, the limiting groove 137b can limit the outer periphery of the controller 310. In this way, the effect of the controller 310 being limited by the limiting groove 137b can be improved, thereby improving the clamping stability of the mounting bracket 113 and the decorative panel assembly 13 on the controller 310.

[0107] Furthermore, the exposed area is the electrical opening 137a formed on the decorative panel assembly 13, and the limiting groove 137b is formed by a peripheral depression of the electrical opening 137a. In this way, the decorative panel assembly 13 itself can be constructed as a non-transparent plate to realize the exposure of the controller 310 by opening the electrical opening 137a, so that the material selection of the decorative panel assembly 13 is wider, and non-transparent materials or transparent materials can be selected. Of course, in other structural forms, the display area can also be formed by constructing a part of the decorative panel assembly 13 itself, that is, the decorative panel assembly 13 has at least two parts, one of which is constructed of a non-transparent material and the other is constructed of a transparent material. This embodiment of the present application is not limited to this. Moreover, based on the basis that the exposed area is the electrical opening 137a, the user can operate the key module of the controller 310 through the electrical opening 137a, and then control the operation of various components in the indoor unit through the electrical control box.

[0108] Referring to Figures 6 and 7 , in some structural configurations, a limit snap 1379 is provided on the surface of the decorative panel assembly 13 facing the mounting bracket 113. The decorative panel assembly 13 also includes an exposed area corresponding to the mounting opening 111a. The limit snap 1379 is positioned adjacent to the exposed area and is used to engage the surface of the controller 310 facing the mounting bracket 113. In this manner, the limit snap 1379 can limit the position of the controller 310, specifically, from the outside to the inside of the panel structure 100, effectively preventing the controller 310 from shifting. The limit snap 1379 and the decorative panel assembly 13 can be integrally formed, thereby enhancing the connection and reducing the number of assembly steps. Alternatively, the limit snap 1379 and the decorative panel assembly 13 can be separate structures, for example, connected by adhesive bonding, etc. This is not a limitation of the present embodiment.

[0109] Referring to FIG. 13 , in some embodiments, the panel structure 100 further includes a limiting structure 30, which is connected to the panel assembly 11 and is used to abut the surface of the controller 310 facing the mounting bracket 113. Thus, by providing the limiting structure 30, it is possible to apply abutting force to the controller 310, so that the controller 310 can better fit the decorative panel assembly 13, thereby achieving a better clamping effect of the decorative panel assembly 13 and the mounting bracket 113 on the controller 301. For example, the limiting structure 30 can be a limiting compression spring, one end of which is fixedly connected to the panel assembly 11, and the other end of which abuts the surface of the controller 310 facing the mounting bracket 113. Thus, the controller 310 can be pressed by the elastic force provided by the limiting compression spring.

[0110] Please continue to refer to Figure 13. Further, the limiting structure 30 includes a support body 31 and a limiting elastic member 33. The support body 31 is connected to the mounting bracket 113 and is located between the support body 31 and the panel 111. One side of the limiting elastic member 33 abuts the surface of the support body 31 facing the panel 111, and the other side is used to abut the surface of the controller 310 facing the mounting bracket 113.

[0111] In this way, the elastic force provided by the limiting elastic member 33 can be used to limit the controller 310 in the direction from the inside to the outside of the panel structure 100, and the support body 31 is connected to the mounting bracket 113 of the panel assembly 11 instead of being connected to the panel 111, which can also prevent the panel 111 from being deformed due to force.

[0112] Exemplarily, the limiting elastic member 33 may be an elastic sponge, and the surface area of ​​the elastic sponge may be greater than or equal to the back area of ​​the controller 310, thereby providing a more balanced elastic force, and the setting of the elastic sponge can prevent the controller 310 from contacting the support body 31 and causing scratches on the controller 310.

[0113] Referring to FIG. 4 , in some embodiments, the decorative panel assembly 13 is movably connected to the panel 111 to reveal or cover the controller 310. In actual use, when the user does not need to use the controller 310 temporarily, the user can manipulate the decorative panel assembly 13 to move relative to the panel 111 to cover the controller 310, thereby preventing dust, water, and other impurities from contacting the controller 310, while also preventing external impact or accidental contact with the controller 310. When the controller 310 is needed, the user can manipulate the decorative panel assembly 13 to move relative to the panel 111 to reveal the controller 310. Optionally, the specific form of movement of the decorative panel assembly 13 and the panel 111 can be flipping, pushing and pulling up and down, or rotating, etc., which is not limited in this embodiment of the present application.

[0114] Please refer to Figures 9 to 11. Furthermore, the decorative panel assembly 13 includes a first decorative panel 135 and a second decorative panel 137. The second decorative panel 137 is disposed around the mounting opening 111a and is provided with an electrical appliance opening 137a corresponding to the mounting opening 111a. This allows the second decorative panel 137 to be matched with the controller 310, enhancing the overall aesthetics and quality. Furthermore, when the second decorative panel 137 is black, white, or gray, it can match the color of the controller 310 and surround the controller 310, highlighting a sense of technology. It is understood that the first decorative panel 135 is provided with an installation window 135a, which corresponds to the electrical appliance opening 137a.

[0115] The first decorative panel 135 is movably connected to the second decorative panel 137 or the panel 111 to reveal or conceal the appliance opening 137a. This allows the user to manipulate the first decorative panel 135 relative to the panel 111. When the user does not need to use the controller 310, the first decorative panel 135 prevents dust, water, and other impurities from reaching the controller 310, while also protecting and shielding the second decorative panel 137. When the user needs to use the controller 310, they can manipulate the first decorative panel 135 to reveal the controller 310.

[0116] Please refer to Figures 9 to 10. Specifically, the first decorative panel 135 may include an outer surface 135b and an inner surface 135c, and the outer surface 135b and the inner surface 135c are arranged back to back. In addition, the first decorative panel 135 is provided with an installation window 1135a that passes through the outer surface 135b and the inner surface 135c, wherein the installation window 1135a may be square, circular, or other shapes.

[0117] Referring to Figures 10 and 11 , the second decorative panel 137 may include a base plate 1371, a first overlapping portion 1371, and a second overlapping portion 1372. Specifically, the base plate 1371 may be square or circular, etc., and may match the shape of the mounting window 1135a. Furthermore, the base plate 1371 may be a high-gloss plate such as an acrylic plate or a painted plate. For example, when the base plate 1371 is an acrylic plate, the acrylic plate may have a high gloss and be aesthetically pleasing and smooth surface. In actual use, when a user operates the controller 310, their line of sight is focused on the controller 310 and the area near the controller 310. When the base plate 1371 has a high gloss, the base plate 1371 of the present application may be more aesthetically pleasing than when the base plate 1371 has a high surface roughness, thereby enhancing the user's visual experience and effectively improving the user's experience.

[0118] The first overlapping portion 1371 can be arranged in a square shape. The first overlapping portion 1371 is connected to the substrate 1371, and at least a portion thereof protrudes outwardly relative to the edge of the substrate 1371. It can be understood that when the first overlapping portion 1371 is connected to the outer side surface of the substrate 1371, a portion of the first overlapping portion 1371 is laminated with the substrate 1371, and the remaining portion protrudes outwardly relative to the edge of the substrate 1371; and when the first overlapping portion 1371 is connected to the outer peripheral surface of the substrate 1371, the first overlapping portion 1371 as a whole protrudes outwardly relative to the edge of the substrate 1371. The embodiment of the present application is not limited to this. Among them, when the user views from the outside, the first overlapping portion 1371 and the substrate 1371 will be seen, while the second overlapping portion 1372 will be hidden by the first decorative plate 135. That is, it can be understood that the first overlapping portion 1371 and the substrate 1371 together constitute the main structure of the second decorative plate 137.

[0119] The second overlapping portion 1372 can be arranged in a square shape. The second overlapping portion 1372 is connected to the substrate 1371, and at least a portion thereof protrudes outwardly relative to the edge of the substrate 1371. It can be understood that when the second overlapping portion 1372 is connected to the inner side surface of the substrate 1371, a portion of the second overlapping portion 1372 is stacked with the substrate 1371, and the remaining portion protrudes outwardly relative to the edge of the substrate 1371. In this way, the portion where the second overlapping portion 1372 is stacked with the substrate 1371 can increase the connection area between the second overlapping portion 1372 and the substrate 1371, thereby improving the connection strength between the two; and when the second overlapping portion 1372 is connected to the outer peripheral surface of the substrate 1371, the second overlapping portion 1372 as a whole protrudes outwardly relative to the edge of the substrate 1371, and the embodiments of the present application are not limited to this.

[0120] In some structural forms, the first overlapping portion 1371 and the base plate 1372 can be two parts of the same plate. This improves the connection strength between the first overlapping portion 1371 and the base plate 1372 and eliminates the need for assembly of the two. The second overlapping portion 1372 can also constitute at least part of another plate. The two plates can be stacked to increase the connection area between them, thereby improving the overall strength of the second decorative plate 137. Furthermore, the two can be integrally formed, further improving the connection strength of the two plates while reducing the number of assembly steps required for the second decorative plate 137.

[0121] In some structural forms, the substrate 1371 is provided with a revealing area, wherein the revealing area is configured to correspond to the controller 310 so that the controller 310 can be revealed by the revealing area. It is understood that the entire substrate 1371 can be made of a transparent material, or a portion of the substrate 1371 can be made of a transparent material, so that the revealing area is formed by the substrate 1371 itself. In this way, the user does not need to remove the second decorative plate 137 and can directly view the display module of the controller 310 through the revealing area, thereby improving the user experience.

[0122] Furthermore, the exposed area is configured as an electrical opening 137a formed on the substrate 1371. Thus, the user can not only directly view the display module of the controller 310 through the electrical opening 137a, but also operate the control module of the controller 310 through the electrical opening 137a, making operation more convenient for the user.

[0123] Please refer to Figures 10 and 11 , in which the base plate 1371 covers the mounting window 1135a. At least a portion of the first overlapping portion 1371 abuts against the outer surface 135b. In other words, the first overlapping portion 1371 may abut against the outer surface 135b in part or in its entirety. Furthermore, the first overlapping portion 1371 may be fixed relative to the outer surface 135b by bonding or other means, which is not limited in this application.

[0124] At least part of the second overlap portion 1372 abuts against the inner surface 135c, that is, part of the second overlap portion 1372 abuts against the inner surface 135c, or the entire second overlap portion 1372 abuts against the inner surface 135c, and the second overlap portion 1372 can be relatively fixed to the inner surface 135c by bonding or other means, and this application does not impose any restrictions on this.

[0125] In summary, the second decorative plate 137 is provided with the first overlapping portion 1371 and the second overlapping portion 1372, and at least a portion of the first overlapping portion 1371 abuts against the outer surface 135b, and at least a portion of the second overlapping portion 1372 abuts against the inner surface 135c. This fixing method enables the panel assembly 11 of this embodiment to have at least two effects:

[0126] First, since the solution of the present application is to abut the outer surface 135b through the first overlapping portion 1371 and the inner surface 135c, and the second overlapping portion 1372 is abutted against the inner surface 135c, the second decorative panel 137 and the first decorative panel 135 have multiple connecting surfaces. Compared with the form of bonding one panel 111 body to another panel 111 body, the solution of the present application can increase the connection area between the first decorative panel 135 and the second decorative panel 137 through the setting of multiple connecting surfaces, which can effectively improve the stability of the connection between the two.

[0127] Second, the second decorative panel 137 abuts against the outer surface 135b of the first decorative panel 135 through the first overlapping portion 1371, and the second overlapping portion 1372 abuts against the inner surface 135c of the first decorative panel 135. When the second decorative panel 137 is subjected to a force from the outside to the inside, the outer surface 135b will resist and limit the first overlapping portion 1371 to prevent the second decorative panel 137 from falling off from the outside to the inside. When the second decorative panel 137 is subjected to a force from the inside to the outside, the inner surface 135c will resist and limit the second overlapping portion 1372 to prevent the second decorative panel 137 from falling off from the inside to the outside. In this way, compared with the existing design in which the second decorative panel 137 and the first decorative panel 135 are connected on one side, it is obvious that the panel assembly 11 of the present application is more adaptable to the more complex force conditions caused by vibration during machine transportation or operation, thereby greatly improving the connection stability between the first decorative panel 135 and the second decorative panel 137.

[0128] It should be noted that, in addition to being applicable to the housing of the indoor unit 300, the panel assembly 11 in the embodiment of the present application can also be applicable to the housing of other modules such as a fan module (not shown in the figure). For example, the fan module can also include a wind wheel, a motor, an electric control box and a controller 310 housed in a receiving chamber. After the user inputs relevant parameters through the controller 310, the motor is controlled by the electric control box to further drive the wind wheel to rotate, etc. The embodiment of the present application does not limit this. The following content still uses the form of the panel assembly 11 applied to the housing of the indoor unit 300 to further explain the situation of the panel assembly 11 of the present application achieving a stable connection between the second decorative panel 137 and the first decorative panel 135 under limited space.

[0129] Please refer to Figures 10 and 11. In some embodiments, the outer surface 135b is recessed to form a mounting groove that communicates with the mounting window 1135a, wherein the mounting groove is used to be embedded in the first overlapping portion 1371. In this way, by forming the mounting groove on the outer surface 135b, embedding the first overlapping portion 1371 into the mounting groove, and connecting the first overlapping portion 1371 to the groove wall of the mounting groove, the first overlapping portion 1371 and the mounting groove have multiple connection surfaces. Compared with the existing form in which only a partial structure of the second decorative plate 137 is connected to the outer surface 135b of the first decorative plate 135, the first overlapping portion 1371 of the solution of the present application is connected to multiple groove walls of the mounting groove formed at different angles. This connection form is obviously more stable than the connection form of a single surface.

[0130] Please refer to Figures 10 and 11. In some embodiments, the inner surface 135c is recessed to form a mounting groove that communicates with the mounting window 1135a, wherein the mounting groove is used to embed the second overlapping portion 1372. In this way, by forming the mounting groove on the inner surface 135c, embedding the second overlapping portion 1372 into the mounting groove, and connecting the second overlapping portion 1372 to the groove wall of the mounting groove, the second overlapping portion 1372 and the mounting groove have multiple connection surfaces. Compared with the existing second decorative plate 137, which is only partially connected to the inner surface 135c of the first decorative plate 135, the second overlapping portion 1372 of the present application is connected to multiple groove walls of the mounting groove at different angles. This connection form is obviously more stable than the connection form of a single surface.

[0131] Please refer to Figures 10 and 11. In some embodiments, the outer surface 135b and the inner surface 135c are both recessed to form installation grooves connected to the installation window 1135a, wherein the installation grooves are used for embedding the first overlapping portion 1371 and the second overlapping portion 1372. In this way, a mounting groove is formed on the outer surface 135b by embedding the first overlap portion 1371 into the mounting groove and connecting the first overlap portion 1371 to the groove wall of the mounting groove, and a mounting groove is formed on the inner surface 135c by embedding the second overlap portion 1372 into the mounting groove and connecting the second overlap portion 1372 to the groove wall of the mounting groove. As a result, the first overlap portion 1371 and the mounting groove have multiple connection surfaces, and the second overlap portion 1372 and the mounting groove have multiple connection surfaces. Compared with the existing second decorative panel 137, which is only partially connected to one surface of the first decorative panel 135, the first overlap portion 1371 and the second overlap portion 1372 of the solution of the present application are connected to multiple groove walls of the mounting groove at different angles. This connection form is obviously more stable than the connection form of one surface.

[0132] Please continue to refer to Figures 10 to 11. For example, the mounting groove includes a first mounting groove 1352 and a second mounting groove 1353. The outer surface 135b is recessed in the direction toward the inner surface 135c to define the first mounting groove 1352, and the inner surface 135c is recessed in the direction toward the outer surface 135b to define the second mounting groove 1353, wherein at least a portion of the first overlapping portion 1371 is embedded in the first mounting groove 1352 and connected to the groove wall of the first mounting groove 1352, and at least a portion of the second overlapping portion 1372 is embedded in the second mounting groove 1353 and connected to the groove wall of the second mounting groove 1353.

[0133] In this way, the first overlapping portion 1371 is embedded in the first mounting groove 1352 and connected to the groove wall of the first mounting groove 1352, and the second overlapping portion 1372 is embedded in the second mounting groove 1353 and connected to the groove wall of the second mounting groove 1353, thereby improving the stability of the connection. It should be noted that the first overlapping portion 1371 can be partially embedded in the first mounting groove 1352 or fully embedded in the first mounting groove 1352, and the second overlapping portion 1372 can be partially embedded in the second mounting groove 1353 or fully embedded in the first mounting groove 1352, and this application does not impose any restrictions on this.

[0134] In some structural forms, the first overlap portion 1371 and the groove wall of the first installation groove 1352 can be connected by at least one of bonding, threaded connection and clamping. In one example, the first overlap portion 1371 can be bonded to the groove wall of the first installation groove 1352, so that there is no need to set an additional connection structure between the first overlap portion 1371 and the groove wall of the first installation groove 1352, so that the structure is simplified and the appearance of the first overlap portion 1371 is more beautiful; in another example, the first overlap portion 1371 can be bonded and threaded to the groove wall of the first installation groove 1352, so that the combination of the two connection forms can effectively improve the connection strength between the first overlap portion 1371 and the groove wall of the first installation groove 1352.

[0135] In some structural forms, the second overlap portion 1372 and the groove wall of the second mounting groove 1353 can be connected by at least one of bonding, threaded connection and clamping. In one example, the second overlap portion 1372 can be bonded to the groove wall of the second mounting groove 1353, so that the second overlap portion 1372 and the groove wall of the second mounting groove 1353 can be avoided from being provided with an additional connection structure, so that the structure is simplified and the appearance of the second overlap portion 1372 is more beautiful; in another example, the second overlap portion 1372 can be bonded and threaded to the groove wall of the second mounting groove 1353, so that the combination of the two connection forms can effectively improve the connection strength between the second overlap portion 1372 and the groove wall of the second mounting groove 1353.

[0136] Referring to Figures 11 and 15 , in some embodiments, the first overlapping portion 1371 and the second overlapping portion 1372 are respectively connected to opposite sides of the substrate 1371. It is understood that, for example, if the substrate 1371 is rectangular, it will have a length direction and a width direction. Therefore, the first overlapping portion 1371 and the second overlapping portion 1372 may be respectively connected to opposite sides of the substrate 1371 along its length direction, or the first overlapping portion 1371 and the second overlapping portion 1372 may be respectively connected to opposite sides of the substrate 1371 along its width direction. This allows the external force applied to the second decorative panel 137 to be more evenly distributed across the substrate 1371, reducing localized stress concentration and thereby preventing excessive deformation or damage to localized areas of the substrate 1371.

[0137] Referring to Figures 10 and 11 , in some structural forms, the portion of the first overlapping portion 1371 that is embedded in the first mounting groove 1352, in a direction away from the base plate 1371, is larger than the portion of the second overlapping portion 1372 that is embedded in the second mounting groove 1353. When the portion of the first overlapping portion 1371 that is embedded in the first mounting groove 1352 is larger in a direction away from the base plate 1371, the connection area between the first overlapping portion 1371 and the wall of the first mounting groove 1352 is larger. As a result, the wall of the first mounting groove 1352 can more effectively block and limit the first overlapping portion 1371, further preventing the second decorative panel 137 from falling from the outside inward. At the same time, when the size of the second overlapping portion 1372 embedded in the second mounting groove 1353 is smaller, that is, the area of ​​the second mounting groove 1353 will also be smaller. In this way, it can avoid the area of ​​the second mounting groove 1353 being too large, which will cause the overall strength of the first decorative panel 135 to be too low, thereby reducing the possibility of the first decorative panel 135 being easily deformed or damaged when subjected to external forces.

[0138] Of course, in other structural forms, the portion of the first overlapping portion 1371 embedded in the first mounting groove 1352 may be equal to or smaller than the size of the second overlapping portion 1372 embedded in the second mounting groove 1353 in the direction away from the substrate 1371. This embodiment of the present application does not limit this.

[0139] In some embodiments, the thickness of the first overlap portion 1371 can be comparable to the depth of the first mounting groove 1352. Thus, when the first overlap portion 1371 is embedded in the first mounting groove 1352, the first overlap portion 1371 is coplanar with the outer surface 135b of the first decorative panel 135. The thickness of the first overlap portion 1371 is less than the depth of the first mounting groove 1352, so that the first overlap portion 1371 is lower than the outer surface 135b. Alternatively, the thickness of the first overlap portion 1371 is greater than the depth of the first mounting groove 1352, so that the first overlap portion 1371 is higher than the outer surface 135b. This arrangement of the embodiment of the present application can make the appearance of the panel assembly 11 more concise, flat, and beautiful. Of course, in other structural forms, the thickness of the first overlap portion 1371 can also be less than the depth of the first mounting groove 1352, or the thickness of the first overlap portion 1371 can be greater than the depth of the first mounting groove 1352. This is not limited in this embodiment of the present application.

[0140] The above description describes the advantages of the stable connection between the second decorative panel 137 and the first decorative panel 135 of the panel assembly 11 of the present application, based on the matching form between the first overlapping portion 1371 and the first mounting groove 1352, and the matching form between the second overlapping portion 1372 and the second overlapping portion 1373. On this basis, to further improve the stability of the connection between the second decorative panel 137 and the first decorative panel 135, please refer to Figures 10 and 11. In some embodiments, the second decorative panel 137 of this embodiment may also include a third overlapping portion 1373, which may be square in shape. Among them, the third overlap portion 1373 is connected to the substrate 1371, and at least part of the third overlap portion 1373 protrudes outward relative to the edge of the substrate 1371. It can be understood that when the third overlap portion 1373 is connected to the side of the substrate 1371 and at least partially abuts against the first decorative panel 135, the connection area with the first decorative panel 135 can be increased through the third overlap portion 1373 to improve the stability of the connection between the substrate 1371 and the first decorative panel 135. Among them, a portion of the third overlapping portion 1373 is laminated with the substrate 1371, and the remaining portion protrudes outward from the edge of the substrate 1371. The portion of the third overlapping portion 1373 that is laminated with the substrate 1371 can increase the connection area between the third overlapping portion 1373 and the substrate 1371, thereby improving the connection strength between the two. When the third overlapping portion 1373 is connected to the outer peripheral surface of the substrate 1371, the third overlapping portion 1373 as a whole protrudes outward from the edge of the substrate 1371. This embodiment of the present application is not limited to this. Specifically, the structural coordination of the third overlapping portion 1373 with the substrate 1371 and the first decorative panel 135 can be any of the following:

[0141] In the first structural form, at least part of the third overlapping portion 1373 can be connected to the outer side surface of the substrate 1371 and abut against the outer surface 135b of the first decorative panel 135. The third overlapping portion 1373 can form a single plate body with the first overlapping portion 1371 and the substrate 1371, and this embodiment of the present application does not impose any restrictions on this. In this way, the substrate 1371 can increase the connection area with the first decorative panel 135 through the third overlapping portion 1373 to improve the stability of the connection between the substrate 1371 and the first decorative panel 135. At the same time, when the third overlapping portion 1373 abuts against the outer surface 135b of the first decorative panel 135, when the second decorative panel 137 is subjected to an outward-inward force, the outer surface 135b of the first decorative panel 135 will resist and limit the third overlapping portion 1373 to prevent the second decorative panel 137 from falling off from the outside to the inside.

[0142] Under this structural form, the number of third overlap portions 1373 can be two, and the two third overlap portions 1373 are both connected to the outer side surface of the substrate 1371, and are connected to the opposite sides of the substrate 1371 and are located between the first overlap portion 1371 and the second overlap portion 1372. For example, the first overlap portion 1371 and the second overlap portion 1372 are connected to the opposite sides of the substrate 1371 along its length direction, and the two third overlap portions 1373 are connected to the opposite sides of the substrate 1371 along its width direction. In this way, the connection area between the substrate 1371 and the first decorative panel 135 can be increased by the two third overlap portions 1373, and the overall force of the second decorative panel 137 is made more balanced.

[0143] Optionally, the outer surface 135b of the first decorative panel 135 may also be provided with a third mounting groove 1356, which is recessed toward the inner surface 135c and connected to the mounting window 1135a. The third overlapping portion 1373 may be embedded in the third mounting groove 1356. In this way, the third overlapping portion 1373 may be limited and pre-positioned by the third mounting groove 1356, and the thickness of the third overlapping portion 1373 may be equivalent to the groove depth of the third mounting groove 1356, so that the overall appearance of the panel assembly 11 is more concise, smooth and beautiful.

[0144] 11 and 15 , in the second structural form, at least a portion of the third overlapping portion 1373 may be connected to the inner side surface of the base plate 1371 and abut against the inner surface 135c of the first decorative panel 135. In this way, the base plate 1371 can increase the connection area with the first decorative panel 135 through the third overlapping portion 1373, thereby improving the stability of the connection between the base plate 1371 and the first decorative panel 135. Furthermore, when the third overlapping portion 1373 abuts against the inner surface 135c of the first decorative panel 135, when the second decorative panel 137 is subjected to an outward force from the inside, the inner surface 135c of the first decorative panel 135 will block and limit the third overlapping portion 1373, thereby preventing the second decorative panel 137 from falling off from the inside.

[0145] In this structural form, the number of third overlapping portions 1373 can be two, and the two third overlapping portions 1373 are both connected to the inner side surface of the base plate 1371, connected to opposite sides of the base plate 1371, and located between the first overlapping portion 1371 and the second overlapping portion 1372. The second decorative plate 137 also includes a third connecting portion 1374, which is connected to the inner side surface of the base plate 1371 and connected between the two third overlapping portions 1373. It is understood that the third connecting portion 1374, the two third overlapping portions 1373, and the second overlapping portion 1372 can constitute a single plate body, making the connection more secure and reducing the number of assembly steps. With the provision of two third overlap portions 1373, for example, the first overlap portion 1371 and the second overlap portion 1372 can be connected to opposite sides of the substrate 1371 along its length direction, and the two third overlap portions 1373 can be connected to opposite sides of the substrate 1371 along its width direction. In this way, the connection area between the substrate 1371 and the first decorative panel 135 can be increased through the two third overlap portions 1373, and the overall force of the second decorative panel 137 can be more balanced.

[0146] Optionally, the inner surface 135c of the first decorative panel 135 may also be provided with a third mounting groove 1356, which is recessed toward the outer surface 135b and connected to the mounting window 1135a. The third overlapping portion 1373 may be embedded in the third mounting groove 1356. In this way, the third overlapping portion 1373 may be limited and pre-positioned by the third mounting groove 1356.

[0147] Furthermore, the inner side surface of the base plate 1371, the second overlapping portion 1372, the third connecting portion 1374, and the two third overlapping portions 1373 collectively define a limiting groove 137b, which is connected to the electrical appliance opening 137a. Thus, the limiting groove 137b can limit the installation of the controller 310, thereby improving the stability of the controller 310 when it is installed in the electrical appliance opening 137a.

[0148] In order to prevent the controller 310 from applying excessive external force to the second decorative panel 137, causing the second decorative panel 137 to fall off from the inside to the outside, under this structural form, part of the bottom wall of the limiting groove 137b can be further recessed to form an air avoidance groove, wherein the air avoidance groove is used to avoid the setting of the controller 310, so that the bottom wall of the limiting groove 137b does not completely contact the controller 310 to transmit force.

[0149] In the third structural form, the number of third overlap portions 1373 can be two, and the two third overlap portions 1373 are connected to opposite sides of the substrate 1371 and are located between the first overlap portion 1371 and the second overlap portion 1372. For example, the first overlap portion 1371 and the second overlap portion 1372 can be connected to opposite sides of the substrate 1371 along its length direction, and the two third overlap portions 1373 can be connected to opposite sides of the substrate 1371 along its width direction. Among them, one of the third overlapping portions 1373 abuts against the inner surface 135c of the first decorative panel 135, and the other of the two third overlapping portions 1373 abuts against the outer surface 135b of the first decorative panel 135. Based on this, the third overlapping portion 1373 abutting against the inner surface 135c of the first decorative panel 135 can form the same plate body with the second overlapping portion 1372, and the third overlapping portion 1373 abutting against the outer surface 135b of the first decorative panel 135 can form the same plate body with the base plate 1371 and the first overlapping portion 1371. This can improve the connection strength while appropriately reducing the number of assembly steps. In summary, the two third overlapping portions 1373 can increase the connection area between the base plate 1371 and the first decorative panel 135, and make the overall force of the second decorative panel 137 more balanced.

[0150] Optionally, in this structural form, the outer surface 135b of the first decorative panel 135 is further provided with a third mounting groove 1356, and the third mounting groove 1356 provided on the outer surface 135b is recessed toward the inner surface 135c, and the third overlapping portion 1373 abutting against the outer surface 135b is embedded in the corresponding third mounting groove 1356. In this way, the third overlapping portion 1373 abutting against the outer surface 135b can be limited and pre-positioned by the third mounting groove 1356 provided on the outer surface 135b, and the depth of the third overlapping portion 1373 can be equivalent to the groove depth of the third mounting groove 1356, so that the overall appearance of the panel assembly 11 is more simple, flat and beautiful.

[0151] On the basis of the third mounting groove 1356 being provided on the outer surface 135b of the first decorative panel 135, the inner surface 135c of the first decorative panel 135 is further provided with a third mounting groove 1356. The third mounting groove 1356 provided on the inner surface 135c is recessed toward the outer surface 135b, and the third overlapping portion 1373 abutting against the inner surface 135c of the first decorative panel 135 is embedded in the corresponding third mounting groove 1356. That is, the inner surface 135c of the first decorative panel 135 and the outer surface 135b of the first decorative panel 135 are also provided with a third mounting groove 1356, and a third overlapping portion 1373 is correspondingly embedded in a third mounting groove 1356. In this way, the third mounting groove 1356 provided on the inner surface 135c can be used to achieve the limitation and pre-positioning of the third overlapping portion 1373 abutting against the inner surface 135c.

[0152] Of course, under this structural form, the third mounting groove 1356 can be provided only on the inner surface 135c of the first decorative panel 135, and no third mounting groove 1356 is provided on the outer surface 135b of the first decorative panel 135. The third mounting groove 1356 provided on the inner surface 135c is recessed toward the outer surface 135b, and the third overlapping portion 1373 abutting against the inner surface 135c of the first decorative panel 135 is embedded in the corresponding third mounting groove 1356. In this way, the third mounting groove 1356 provided on the inner surface 135c can be used to limit and pre-position the third overlapping portion 1373 abutting against the inner surface 135c.

[0153] Please refer to Figures 7 and 8 . To facilitate the user's operation of the second decorative panel 137, the first decorative panel 135 and the second decorative panel 137 or the panel 111 can be configured to move in a flipping manner. Specifically, a pivot 1376 is provided on one side of the second decorative panel 137 or the panel 111. The first decorative panel 135 is pivotally connected to the second decorative panel 137 or the panel 111 via the pivot 1376, so that the first decorative panel 135 can rotate relative to the second decorative panel 137 about the pivot 1376. In this way, by adopting a flipping manner, compared to a push-and-pull manner, this embodiment does not require a slide rail or other structural member between the first decorative panel 135 and the second decorative panel 137 or the panel 111. This simplifies the structure of the decorative panel assembly 13 and the panel 111, and makes actual operation more convenient. When revealing or covering the controller 310, the user only needs to perform a simple flipping action, which is more convenient.

[0154] Referring to Figures 7 and 8 , the first decorative panel 135 or panel 111 further comprises a clamping portion 1354 detachably connected to a pivot 1376. Clamping portion 1354 can clamp pivot 1376 for rotation about pivot 1376. This arrangement allows clamping portion 1354 to rotate about pivot 1376 while clamping pivot 1376, allowing the first decorative panel 135 to reveal or conceal the appliance opening 137a. Furthermore, the detachable arrangement of clamping portion 1354 and pivot 1376 allows the first decorative panel 135 to be disassembled and assembled, facilitating maintenance or replacement of the first decorative panel 135, providing users with more options.

[0155] 7 and 8 , the second decorative plate 137 or the panel 111 is provided with a fixing seat 1377, through which the pivot 1376 is disposed. The fixing seat 1377 is also provided with an escape space 1377a for circumventing the clamping portion 1354. The escape space 1377a prevents the clamping portion 1354 from interfering with the fixing seat 1377 during rotation, thereby increasing the range of rotation of the clamping portion 1354 and, in turn, increasing the range of rotation of the first decorative plate 135. This prevents the second decorative plate 137 from obstructing the electrical appliance opening 137a, making it easier for the user to operate the controller 310.

[0156] Please refer to Figures 7 and 8 in combination. In some structural forms, the second decorative plate 137 or the panel 111 is provided with one of the connecting buckle 1355 and the connecting groove 1378, and the first decorative plate 135 is provided with the other of the connecting buckle 1355 and the connecting groove 1378, wherein the connecting buckle 1355 is buckled into the connecting groove 1378.

[0157] Thus, when the first decorative panel 13 covers the appliance opening 137a, the fastening buckle 1355 and the fastening groove 1378 can be engaged to achieve relative fixation between the first decorative panel 13 and the second decorative panel 137 or the panel 111, thereby improving stability. Furthermore, when the first decorative panel 13 needs to open the appliance opening 137a, the fastening buckle 1355 can be deformed to detach from the fastening buckle 1355, making operation convenient and quick. It is understood that the fastening buckle 1355 can be provided on the second decorative panel 137 or the panel 111, and the fastening groove 1378 can be provided on the first decorative panel 135, or the fastening buckle 1355 can be provided on the second decorative panel 137 or the panel 111, and the fastening groove 1378 can be provided on the first decorative panel 135. This embodiment of the present application is not limited thereto.

[0158] Of course, in addition to the buckling form of the connecting buckle 1355 and the connecting groove 1378, the second decorative plate 137 or the panel 111 can also be provided with a first magnetic component, and the first decorative plate 135 can be provided with a second magnetic component that is magnetically attracted to the first magnetic component. In this way, the first decorative plate 13 can also be relatively fixed to the second decorative plate 137 or the panel 111 when covering the electrical appliance opening 137a through magnetic coordination.

[0159] Please refer to Figures 4 and 5. In some embodiments, the panel assembly 11 can be provided with a plurality of first mounting portions 115 and a plurality of second mounting portions 117 at intervals. For example, when the panel assembly 11 is square in shape, the plurality of first mounting portions 115 and the plurality of second mounting portions 117 can be arranged at intervals along the circumference of the panel assembly 11, or can be arranged at intervals along the length or width of the panel assembly 11. This embodiment of the present application is not limited to this. Correspondingly, the decorative panel assembly 13 can be provided with a plurality of first connecting portions 131 and a plurality of second connecting portions 133, wherein a first connecting portion 131 is engaged with a first mounting portion 115, and a second connecting portion 133 is connected to a second mounting portion 117 via a connector (not shown in the figure).

[0160] In some structural forms of the first connecting portion 131 and the first mounting portion 115, the first connecting portion 131 may be a buckle 1311 and the first mounting portion 115 may be a slot to achieve a snap-fit ​​fit between the first connecting portion 131 and the first mounting portion 115; of course, in other structural forms, the first connecting portion 131 may be a slot and the first mounting portion 115 may be a buckle 1311, and the embodiments of the present application do not limit this.

[0161] In some structural forms of the second connecting portion 133 and the second mounting portion 117, the second connecting portion 133 may be a threaded column 1331, and the second mounting portion 117 may be a mounting hole 117a. In this way, the connecting member may be a threaded member, and the second mounting portion 117 and the second connecting portion 133 may be connected by a threaded member; of course, in other structural forms, the second connecting portion 133 may be a mounting hole 117a, and the second mounting portion 117 may be a threaded column 1331. In addition, the second connecting portion 133 and the second mounting portion 117 may both be mounting holes 117a, and the connecting member may be a rivet, screw, bolt, etc., which is then passed through the second connecting portion 133 and the second mounting portion 117 to achieve connection. The embodiments of the present application do not impose any restrictions on this.

[0162] In summary, by providing a plurality of first mounting portions 115 and a plurality of second mounting portions 117 at intervals on the panel assembly 11, and providing a plurality of first connecting portions 131 and a plurality of second connecting portions 133 on the decorative plate assembly 13, and simultaneously snapping the first connecting portions 131 and the first mounting portions 115 together, and connecting the second connecting portions 133 and the second mounting portions 117 together via a connector, the panel structure 100 of this embodiment has the following three effects:

[0163] First, in terms of connection stability, since the connection between the second connection portion 133 and the second mounting portion 117 is added on top of the snap-fit ​​arrangement between the first connection portion 131 and the first mounting portion 115, even if the first connection portion 131 or the first mounting portion 115 as the snap 1311 undergoes structural deformation, fracture, or the like after long-term use, resulting in connection failure, the panel structure 100 of this embodiment can still achieve a stable connection between the panel assembly 11 and the decorative panel group 13 through the second connection portion 133 and the second mounting portion 117, thereby improving the structural stability of the panel structure 100;

[0164] Second, in terms of assembly efficiency, in the actual assembly process, the panel structure 100 of this embodiment can realize the pre-fixed connection between the panel assembly 11 and the decorative panel group 13 by snapping the first connecting portion 131 with the first mounting portion 115. On this basis, the panel assembly 11 and the decorative panel group 13 are finally connected by connecting the second connecting portion 133 with the second mounting portion 117 using a connecting piece. In this way, the accuracy of the relative position between the panel assembly 11 and the decorative panel group 13 can be ensured by the pre-fixed connection, and the position error between the second connecting portion 133 and the second mounting portion 117 in the subsequent assembly process can be avoided, thereby effectively improving the assembly efficiency and assembly accuracy of the panel assembly 11 and the decorative panel group 13.

[0165] Third, in terms of the sealing effect, by arranging multiple first mounting parts 115 and multiple second mounting parts 117 at intervals on the panel assembly 11, and correspondingly arranging multiple first connection parts 131 that are engaged with the first mounting parts 115 and multiple second connection parts 133 that are connected with the second mounting parts 117 on the decorative panel group 13, the connection area between the panel assembly 11 and the decorative panel group 13 is effectively increased. In this way, the facing surfaces of the panel assembly 11 and the decorative panel group 13 are brought closer, effectively reducing the size of the gap between the facing surfaces of the panel assembly 11 and the decorative panel group 13, reducing the possibility of impurities such as dust or water entering through the gap, thereby reducing the possibility of the controller 310 being affected by impurities such as dust or water.

[0166] Please refer to Figures 4 to 6. In some embodiments, the first mounting portion 115 can be the above-mentioned slot, and specifically can include a first slide groove 115a and a second slide groove 115b provided on the panel assembly 11. The first slide groove 115a and the second slide groove 115b are connected, and the opening of the first slide groove 115a is larger than the second slide groove 115b. The first connecting portion 131 can include a buckle 1311, which can be inserted into the second slide groove 115b along the first slide groove 115a, and partially abut against the surface of the panel assembly 11 facing away from the decorative panel group 13.

[0167] Among them, the buckle 1311 has a root and a hook portion that are roughly L-shaped with the connection. In actual use, the buckle 1311 can be first extended into the first slide groove 115a. At this time, the root and the hook portion of the buckle 1311 can both pass through the first slide groove 115a. Then, the buckle 1311 is slid along the direction from the first slide groove 115a to the second slide groove 115b to be stuck in the second slide groove 115b. In this process, the root of the buckle 1311 will not be affected by the groove wall surface of the first slide groove 115a and the second slide groove 115b. The second chute 115b is deformed by the interference of the groove wall surface, and finally the hook portion of the clip 1311 can abut against the surface of the panel assembly 11 facing away from the decorative plate assembly 13 to achieve a snap connection. In the process of disconnection, that is, when the clip 1311 slides from the second chute 115b to the first chute 115a and is disconnected from the first chute 115a, the clip 1311 will not be deformed by the interference of the groove wall surface of the second chute 115b and the groove wall surface of the first chute 115a. In this way, compared with the method of the clip 1311 being inserted into or out of the slot by self-deformation, the embodiment of the present application can avoid the clip 1311 from being damaged by repeated deformation, thereby effectively extending the service life of the clip 1311.

[0168] In some structural forms, the buckle 1311 and the decorative panel group 13 can be an integrated structure, which can improve the connection strength between the two and reduce the assembly steps for the two; of course, in other structural forms, the buckle 1311 and the decorative panel group 13 can be a split structure, so that after long-term use, the damaged buckle 1311 can be replaced to extend the service life of the decorative panel group 13. The embodiments of the present application do not limit this.

[0169] Furthermore, the buckle 1311 can be provided on the side of the decorative panel assembly 13 facing the panel assembly 11. In this way, the decorative panel assembly 13 can shield the buckle 1311, achieving a concealed effect. Thus, when a user views the panel structure 100 from the outside, the buckle 1311 is not visible, and the decorative panel assembly 11 also shields the first mounting portion 115, thereby effectively improving the external aesthetics of the panel structure 100. Of course, the buckle 1311 can also be provided on the circumferential surface of the decorative panel assembly 13, and this embodiment of the present application is not limited thereto.

[0170] Continuing to refer to Figures 4 to 6, in some embodiments, the second mounting portion 117 can be a mounting hole 117a provided on the panel assembly 11, and the second connecting portion 133 can include a threaded column 1331 provided on a side of the decorative plate assembly 13 facing the panel assembly 11. The second mounting portion 117 and the second connecting portion 133 are connected by a threaded member. It is understood that the threaded column 1331 can have an internal thread formed therein, while the threaded member has an external thread. The threaded member passes through the mounting opening 111a and is then inserted into the threaded column 1331, so that the threaded member and the threaded column 1331 are connected by the cooperation of the external and internal threads.

[0171] Thus, during the installation process, compared to the connection form in which a threaded member passes through the mounting hole 117a of the panel assembly 11 and the mounting hole 117a of the decorative panel assembly 13 and is then threadedly connected to the threaded member by a nut, the embodiment of the present application does not require the steps of passing the threaded member through the two mounting holes 117a and tightening the nut, thereby improving installation efficiency. In addition, the form in which the threaded column 1331 is directly set on the decorative panel assembly 13 can improve the bearing capacity of the threaded column 1331 on the panel assembly 11 through the decorative panel assembly 13. At the same time, there is no need to open the mounting hole 117a in the decorative panel assembly 13, thereby improving the external aesthetics of the decorative panel assembly 13 and avoiding the exposure of the threaded member. In addition, when the threaded column 1331 is set on the side of the decorative panel assembly 13 facing the panel assembly 11, the decorative panel assembly 13 can achieve the shielding effect of the threaded column 1331, thereby achieving the effect of hiding the threaded column 1331.

[0172] Continuing to refer to Figures 4 to 6 , in some structural forms, there are multiple first connecting portions 131 spaced apart along the periphery of the decorative panel assembly 13, and multiple second connecting portions 133 spaced apart along the periphery of the decorative panel assembly 13. With this arrangement, when the multiple first connecting portions 131 are pre-secured by snapping together with the multiple first mounting portions 115, the decorative panel assembly 11 is aligned with the panel assembly 11 via its periphery, thereby improving the overall alignment accuracy of the decorative panel assembly 11 and the panel assembly 11. Furthermore, the coordination of the multiple first connecting portions 131 and the multiple second connecting portions 133 allows for a tight connection between the panel assembly 11 and the decorative panel assembly 13 in the circumferential direction, effectively improving the connection stability between the panel assembly 11 and the decorative panel assembly 13 and the sealing effect of the gap between the panel assembly 11 and the decorative panel assembly 13.

[0173] In order to further enhance the connection stability between the panel assembly 11 and the decorative panel assembly 13, please continue to refer to Figures 4 to 6. Furthermore, the decorative panel assembly 13 is provided with an exposed area for corresponding to the controller 310, wherein at least one second connection portion 133 is provided adjacent to the exposed area to cooperate with the second connection portion 133. With this arrangement, the panel assembly 11 of the embodiment of the present application is connected to the decorative panel assembly 13 at the same time as the periphery of the decorative panel assembly 13. The portion of the panel assembly 11 adjacent to the mounting opening 111a thereof is also connected to the decorative panel assembly 13. This increases the connection area between the panel assembly 11 and the decorative panel assembly 13, thereby enhancing the connection stability between the two. Furthermore, the periphery and the portion near the center of the decorative panel assembly 13 are both connected to the panel assembly 11. While enhancing the connection stability, this further allows the panel assembly 11 and the decorative panel assembly 13 to be more closely attached, further reducing the possibility of impurities entering through the gap formed between the panel assembly 11 and the decorative panel assembly 13.

[0174] Exemplarily, at least two second connection portions 133 are arranged adjacent to the exposed area, and the two second connection portions 133 are symmetrically located on both sides of the exposed area, thereby improving the connection stability between the panel assembly 11 and the decorative panel group 13 and the sealing effect of the gap.

[0175] Furthermore, the first mounting portion 115 can be provided on the panel 111, while the second mounting portion 117 can be provided on the mounting bracket 113, and a relief opening 111b can be provided on the panel 111 corresponding to the second connection portion 133. It is understood that when the panel assembly 11 is subjected to force, the second mounting portion 117 connected to the second connection portion 133 is the primary force point, while the first mounting portion 115 connected to the first connection portion 131 as a pre-fixed clamping form is the secondary force point. In this way, the mounting bracket 113 can serve as the primary force-bearing member, and the panel 111 can serve as the secondary force-bearing member, making the force distribution more reasonable and achieving a stepped force effect, thereby reducing the possibility of deformation of the panel 111, which is an exterior component, due to excessive force. Of course, in other structural forms, the first mounting portion 115 can also be provided on the mounting bracket 113, and the second mounting portion 117 can be provided on the panel 111. This embodiment of the present application is not limited to this.

[0176] It can be understood that when the first mounting portion 115 is in the form of a card slot and is directly connected to the first connecting portion 131, the threaded column 1331 does not need to slide in the avoidance opening 111b. Therefore, the function of the avoidance opening 111b in this form is to avoid the setting of the threaded column 1331.

[0177] In the form in which the first mounting portion 115 includes a first slide groove 115a and a second slide groove 115b, and the buckle 1311 can slide in the first slide groove 115a and the second slide groove 115b, the avoidance opening 111b is set in a long strip shape, and its extension direction is consistent with the direction of the first slide groove 115a toward the second slide groove 115b. In this way, the function of the avoidance opening 111b is to avoid the setting of the threaded column 1331, and to allow the threaded column 1331 to slide, thereby avoiding interference between the threaded column 1331 and the panel 111 during the sliding process of the buckle 1311.

[0178] Optionally, the threaded column 1331 may include a column body and a step portion, the step portion being connected to the side of the mounting bracket 113 of the decorative panel group 13 facing the panel assembly 11, and the column body being connected to the side of the step portion facing away from the decorative panel group 13, and being connected to the second mounting portion 117 by a threaded member, wherein the step portion can be slid into the avoidance opening 111b, so that the column body can cooperate with the step portion to achieve cooperation with the second mounting portion 117, and the structure is simpler and easier to produce.

[0179] The first connection portion 131 and the second connection portion 133 may both be provided on the first decorative plate 135. In this way, deformation caused by the connection between the second decorative plate 137 and the panel 111 and the mounting bracket 113 of the panel assembly 11 can be avoided, thereby ensuring the durability and aesthetics of the second decorative plate 137. Alternatively, the first connection portion 131 and the second connection portion 133 may both be provided on the second decorative plate 137. In this way, deformation caused by the connection between the first decorative plate 135 and the panel 111 and the mounting bracket 113 of the panel assembly 11 can be avoided, thereby ensuring the durability and aesthetics of the first decorative plate 135. The first connection part 131 can also be set on the second decorative panel 137, and the second connection part 133 can be set on the first decorative panel 135. In this way, the first connection part 131 and the second connection part 133 are respectively connected to the panel 111 and the mounting bracket 113 of the panel assembly 11 to share the force evenly, and the first connection part 131 as the buckle 1311 is set on the second decorative panel 137 which mainly plays a decorative effect. In this way, the second decorative panel 137 can be prevented from being deformed due to excessive force. Of course, the first connection part 131 can also be set on the first decorative panel 135, and the second connection part 133 can be set on the second decorative panel 137.
