[0057] To make the purpose, technical solutions and advantages of the present application clearer, the following will further describe the embodiments of the present application in detail with reference to the accompanying drawings.

[0058] 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. On the contrary, they are merely examples of the apparatus and methods consistent with some aspects of the present application as detailed in the appended claims.

[0059] In the description of the present application, it should be understood that the terms "first", "second", etc. are used for descriptive purposes only and cannot be construed as indicating or implying relative importance. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances. In addition, in the description of the present application, unless otherwise specified, "a plurality" means two or more. "And / or" describes the association relationship of associated objects and indicates that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally represents an "or" relationship between the associated objects before and after.

[0060] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs. The terms used in the description of this specification are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0061] The indoor unit includes a casing and a panel structure, where the panel structure covers the casing and is also used to fix the controller. However, the panel structure in the prior art usually includes a panel and a connection to the mounting bracket, and the controller is fixed to the panel structure by being mounted on the mounting bracket. However, in the way of fixing the controller only through the mounting bracket, the area for fixing the controller is small, and it is easy to cause the controller to fall off the panel structure due to poor connection stability.

[0062] To solve the above problems, please refer to Figure 1 , on the one hand, the present application proposes a heating, ventilation and air conditioning (HVAC) system, which includes but is not limited to devices such as air conditioners, multi-connected units, heat pumps, water heaters, pool machines, etc. Taking an HVAC device with a refrigerant as the heating medium and water as the heating object as an example, the HVAC system of the HVAC device may include an indoor unit for heating water disposed indoors and an outdoor unit that can be disposed outdoors and exchanges heat with the external environment, and the indoor unit is connected to the outdoor unit. Figure 1The partial structure of the indoor unit 300 is shown. The indoor unit 300 may include a water circulation flow path and refrigerant pipes. Refrigerant flows through the refrigerant pipes. The indoor unit 300 heats the water by exchanging heat between the refrigerant in the refrigerant pipes and the water in the water circulation flow path, so as to heat the water to output water at a set temperature.

[0063] Specifically, the indoor unit 300 includes a housing. The housing is provided with a panel structure 100. It can be understood that the indoor unit further includes refrigerant pipes (not shown in the figure), a controller 310, an electric heating device (not shown in the figure), an electric control box (not shown in the figure), a heat exchanger (not shown in the figure), a water pump (not shown in the figure), a storage water tank (not shown in the figure), etc. The controller is arranged on the panel structure 100 of the housing. Others, such as refrigerant pipes, electric heating devices, heat exchangers, water pumps, etc., are arranged inside the housing. The heat exchanger, the storage water tank, and the water pump are connected by water pipes to form a water circulation flow path. Among them, the heat exchanger has two inlets and two outlets. A refrigerant pipe passes through between a set of interconnected inlets and outlets, and a water medium passes through between another set of interconnected inlets and outlets. When the water medium flows through the heat exchanger, the refrigerant pipe in the heat exchanger contacts the water, and the refrigerant in the refrigerant pipe dissipates heat to heat up the water in the heat exchanger. The water pump provides the power for the water to circulate. The electric heating device can be arranged between the heat exchanger and the storage water tank, that is, the water heated by the heat exchanger is reheated in the electric heating device and enters the storage water tank through the water pipe. The electric heating device plays an auxiliary role in the heat supply of the heat exchanger in a low-temperature environment, so that the water temperature in the storage water tank is increased under the action of the electric heating device, achieving a better heating effect and improving the energy efficiency of the unit. The storage water tank is used to store or transport the water at a set temperature into an external device. The external device can be a floor heating pipeline or a user's domestic water pipe, etc., so as to realize the user's heating demand.

[0064] The outdoor unit may include components such as an evaporator, a compressor, and an expansion valve. The evaporator, the compressor, the heat exchanger, and the expansion valve are sequentially connected in a cycle through refrigerant pipes. When the heating and ventilation equipment works, the refrigerant in the evaporator absorbs heat from the air, and the refrigerant changes from a low-temperature and low-pressure gas to a high-temperature and low-pressure gas; then the high-temperature gas is compressed by the compressor, so that the refrigerant forms a high-temperature and high-pressure liquid; the high-temperature and high-pressure liquid exchanges heat with the water in the water circulation flow path through the heat exchanger, so that the water temperature in the water circulation flow path rises, and the refrigerant becomes a low-temperature and high-pressure liquid; the low-temperature and high-pressure liquid becomes a low-temperature and low-pressure gas through the expansion valve, and then circulates back to the evaporator again, thus completing the cycle process of the refrigerant.

[0065] Please refer to Figures 2 to 4, in the embodiment of the present application, the indoor unit 300 forms a receiving cavity with an opening inside the casing, and the panel structure 100 covers the opening and is connected to the side wall of the casing that encloses the receiving cavity. The controller 310 is installed on the panel structure 100, while the refrigerant pipe, the electric heating device, the heat exchanger, the water pump, etc. are received in the receiving cavity. It can be understood that the controller 310 can be electrically connected to the electric control box, so that after the user operates the controller 310 to input relevant parameters, the controller 310 transmits the signal to the electric control box, and then controls components such as the heat exchanger and the electric heating device through the electric control box. For example, after inputting relevant temperature parameters through the controller 310, the specific operation mode of components such as the heat exchanger or the electric heating device is controlled through the electric control box. Specifically, the controller 310 can have a display module and a button module. The display module can display relevant parameter information, and the button module can be operated by the user to input the required relevant parameters or select the required relevant working mode.

[0066] To prevent 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 the present application includes a panel assembly 11 and a decorative panel group 13. Among them, the panel assembly 11 is connected to the side wall of the casing that encloses the receiving cavity to cover the opening of the receiving cavity, and the decorative panel group 13 is connected to the panel assembly 11.

[0067] The panel assembly 11 includes a panel 111 and a mounting bracket 113. The panel 111 can be generally square-shaped, and the shape of the panel 111 is adapted to the shape of the opening. The material of the panel 111 can be a metal material, such as aluminum or stainless steel, etc., to have advantages such as better structural strength, better corrosion resistance and oxidation resistance, etc. Of course, the material of the panel 111 can also be a plastic material to have advantages such as a lighter overall weight. The embodiment of the present application does not limit this.

[0068] The mounting bracket 113 can be generally rectangular-shaped, and the material of the mounting bracket 113 can be a metal material, such as aluminum or stainless steel, etc., to have advantages such as better structural strength, better corrosion resistance and oxidation resistance, etc. Of course, the material of the mounting bracket 113 can also be a plastic material to have advantages such as a lighter overall weight. The embodiment of the present application does not limit this.

[0069] The decorative panel group 13 can be in a square shape, a circular shape, an irregular shape, etc. The decorative panel group 13 can be in the form of a sheet such as an acrylic sheet or a painted sheet, so as to have advantages such as a relatively high gloss, a relatively flat surface, and relatively bright colors, etc. This application does not limit this. It can be understood that compared with the panel assembly 11, the decorative panel group 13 has better aesthetics and a better decorative effect, so as to improve the overall aesthetics and texture effect of the panel structure 100. Exemplarily, the main structure of the decorative panel group 13 can be a black acrylic sheet. In this way, while improving the overall aesthetic appearance, the sense of technology of the panel structure 100 can be improved.

[0070] 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 to clamp and fix the controller 310. It can be understood that it can be that the mounting bracket 113 is 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, the cooperation is realized to clamp and fix the controller 310; it can also be that the decorative panel group 13 is 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, the cooperation is realized to clamp and fix the controller 310; it can also be that the mounting bracket 113 and the decorative panel group 13 are respectively connected to the panel 111. On this basis, the cooperation is realized to clamp and fix the controller 310. The embodiments of this application do not limit this.

[0071] Among them, on the basis of the connection between the mounting bracket 113 and the panel 111, a flange can be formed on the periphery of the mounting bracket 113, and the flange is welded to the panel 111. In this way, the connection area with the panel 111 can be increased through the flange, and a relatively fixed connection form of welding is adopted to realize 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 snap connection or bonding, etc. The embodiments of this application do not limit this.

[0072] In this way, the cooperation between the mounting bracket 113 and the decorative panel group 13 realizes the clamping and fixing of the controller 310. Compared with the related art in which only the mounting bracket is used to fix the controller 310, in the clamping form of the embodiments of this application, the connection area of the panel structure 100 to the controller 310 can be increased, and the wrapping and fixing of the controller 310 can be increased by means of 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 falling off due to detachment from the panel structure 100 can be reduced.

[0073] Please continue to refer to Figures 4 to 5In some embodiments, the panel 111 is provided with an installation opening 111a for installing the controller 310. Herein, the installation bracket 113 and the decorative panel group 13 are respectively connected to two opposite surfaces of the panel 111 along its thickness direction, so as to cooperate to clamp the controller 310 and fix the controller 310 at the installation opening 111a.

[0074] It can be understood that the decorative panel group 13 is connected to the outer surface of the panel 111, and the installation bracket 113 is connected to the inner surface of the panel 111. In this way, the decorative panel group 13 can be located outside the panel 111 to achieve a decorative effect, and when the controller 310 is fixed at the installation opening 111a, the panel 111 and the controller 310 can cooperate to block the installation bracket 113, further improving the aesthetics of the indoor unit 300.

[0075] Moreover, compared with the case where the decorative panel group 13 is located inside the panel 111 and the panel 111 itself needs to be configured in a form for exposing the transparent part of the controller 310, the entire panel 111 in this embodiment can be made of a metal material. In this way, the structure of the panel 111 can be relatively simple and can be manufactured by one-time processing, making the manufacturing more convenient.

[0076] Please refer to Figures 4 to 6 , further, the decorative panel group 13 is provided with a limiting groove 137b for the controller 310 to be embedded. The groove wall of the limiting groove 137b cooperates with the installation bracket 113 to clamp and fix the controller 310.

[0077] It can be understood that the limiting groove 137b can perform a limiting setting on the outer edge of the controller 310. Thus, there will be multiple limiting surfaces between the controller 310 and the limiting groove 137b. The groove wall of the limiting groove 137b can play a role in limiting the controller 310 in the direction from the inside to the outside, the up-down direction, and the left-right direction of the panel structure 100. Compared with the form in which the decorative panel group 13 only limits the controller 310 through one surface, in the solution of this application embodiment, the controller 310 cooperates with the multiple groove walls of the limiting groove forming different angles. Such a limiting and clamping effect is obviously more stable than the limiting form of one surface connection.

[0078] In other embodiments, it can also be that the plate surface of the decorative panel group 13 directly cooperates with the installation bracket 113 to clamp and fix the controller 310. The embodiments of this application do not limit this.

[0079] Please refer to Figure 6, in some structural forms, the decorative panel group 13 is provided with an exposed area corresponding to the installation opening 111a, and the limiting groove 137b is arranged around the outside of the exposed area. The light emitted by the display module of the controller 310 can penetrate outward through the exposed area, enabling the user to obtain the display information of the display module on the outside of the panel structure 100. In this way, on the basis that the limiting groove 137b surrounds the outside of the exposed area, the limiting groove 137b can limit the outer peripheral edge of the controller 310. In this way, the effect of the controller 310 being limited by the limiting groove 137b can be improved, and further the clamping stability of the installation bracket 113 and the decorative panel group 13 on the controller 310 can be improved.

[0080] Further, the exposed area is an exposed opening 137a formed on the decorative panel group 13, and the limiting groove 137b is formed by the depression of the peripheral edge of the exposed opening 137a. In this way, the decorative panel group 13 itself can be constructed as a non-transparent panel member to expose the controller 310 by opening the exposed opening 137a. Thus, the material selection of the decorative panel group 13 is wider, and non-transparent or transparent materials can be selected. Of course, in other structural forms, the display area can also be formed by a part of the decorative panel group 13 itself, that is, the decorative panel group 13 has at least two parts. Among them, one part is constructed of non-transparent material, and the other part is composed of transparent material. The embodiments of the present application do not limit this. And, on the basis that the exposed area is the exposed opening 137a, the user can operate the button module of the controller 310 through the exposed opening 137a, and then control the components in the indoor unit to work through the electric control box.

[0081] Please refer to Figures 6 to 7 , in some structural forms, the plate surface of the decorative panel group 13 facing the installation bracket 113 is provided with a limiting buckle 1379, and the decorative panel group 13 is provided with an exposed area corresponding to the installation opening 111a. Among them, the limiting buckle 1379 is arranged adjacent to the exposed area and is used to clamp the surface of the controller 310 facing the installation bracket 113. In this way, the controller 310 can also be limited by the limiting buckle 1379. Specifically, the controller 310 is limited in the direction from the outside to the inside of the panel structure 100. In this way, the position deviation of the controller 310 can be effectively avoided. Among them, the limiting buckle 1379 and the decorative panel group 13 can be an integral structure, which can improve the connection stability between the two and reduce the assembly steps. Of course, the limiting buckle 1379 and the decorative panel group 13 can also be a split structure, for example, connected by bonding or other means. The embodiments of the present application do not limit this.

[0082] Please refer to Figure 13, in some embodiments, the panel structure 100 further includes a limiting structure 30. The limiting structure 30 is connected to the panel assembly 11 and is used to abut against the surface of the controller 310 facing the mounting bracket 113. In this way, through the setting of the limiting structure 30, the abutting force on the controller 310 can be realized, so that the controller 310 can better fit the decorative panel group 13, and further the clamping effect of the decorative panel group 13 and the mounting bracket 113 on the controller 301 is better. Exemplarily, the limiting structure 30 can be a limiting compression spring. One end of the limiting compression spring is fixedly connected to the panel assembly 11, and the other end abuts against the surface of the controller 310 facing the mounting bracket 113. In this way, the controller 310 can be pressed by the elastic force provided by the limiting compression spring.

[0083] 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, located between the support body 31 and the panel 111, and one side of the limiting elastic member 33 abuts against the surface of the support body 31 facing the panel 111, and the other side is used to abut against the surface of the controller 310 facing the mounting bracket 113.

[0084] 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 the panel 111, so that the panel 111 can also be prevented from deforming due to force.

[0085] Exemplarily, the limiting elastic member 33 can be an elastic sponge body, and the surface area of the elastic sponge body can be greater than or equal to the back area of the controller 310. In this way, a more balanced elastic force can be provided, and the setting of the elastic sponge body can be used to prevent the controller 310 from being scratched due to contact with the support body 31.

[0086] Please refer to Figure 4 , in some embodiments, the decorative panel group 13 is movably connected to the panel 111 to expose or cover the controller 310. During actual use, when the user does not need to use the controller 310 temporarily, the user can control the decorative panel group 13 to move relative to the panel 111 to cover the controller 310, so as to avoid impurities such as dust or water from contacting the controller 310, and at the same time, it can also avoid external impacts or accidental touches on the controller 310. When the user needs to use the controller 310, the user can control the decorative panel group 13 to move relative to the panel 111 to expose the controller 310. Optionally, the moving form of the decorative panel group 13 and the panel 111 can specifically be forms such as flipping, pushing and pulling up and down, or rotating, etc. The embodiments of the present application do not limit this.

[0087] Please refer to Figures 9 to 11 , further, the decorative panel group 13 includes a first decorative panel 135 and a second decorative panel 137. The second decorative panel 137 is arranged around the mounting opening 111a and is provided with an exposure opening 137a corresponding to the mounting opening 111a. In this way, the controller 310 can be matched through the second decorative panel 137 to improve the overall external aesthetics and texture effect. And when the second decorative panel 137 is selected in colors such as black, white or gray, etc., it can match the color of the controller 310 and surround the controller 310 to highlight the sense of technology. It can be understood that the first decorative panel 135 is provided with an open mouth 135a, wherein the open mouth 135a is arranged corresponding to the exposure opening 137a.

[0088] Among them, the first decorative panel 135 is movably connected to the second decorative panel 137 or the panel 111 to be able to expose or cover the exposure opening 137a. In this way, the user can manipulate the first decorative panel 135 to make the first decorative panel 135 move relative to the panel 111. When the user does not need to use the controller 310 temporarily, the first decorative panel 135 can prevent impurities such as dust or water from contacting the controller 310, and can also play a role in protecting and shielding the second decorative panel 137. And when the controller 310 needs to be used, the user can manipulate the first decorative panel 135 to expose the controller 310.

[0089] Please refer to Figures 7 to 8 , and in order to facilitate the user to operate the second decorative panel 137, the specific moving form of the first decorative panel 135 and the second decorative panel 137 or the panel 111 can be set as a flipping form. Specifically: a pivot 1376 is arranged on one side of the second decorative panel 137 or the panel 111, and the first decorative panel 135 is pivotally connected to the second decorative panel 137 or the panel 111 through the pivot 1376 so that the first decorative panel 135 can rotate around the pivot 1376 relative to the second decorative panel 137. In this way, by adopting the flipping form, compared with forms such as pushing and pulling up and down, etc., in this embodiment, there is no need to set structural members such as slide rails between the first decorative panel 135 and the second decorative panel 137 or the panel 111, which simplifies the structures of the decorative panel group 13 and the panel 111, and the actual operation is more convenient. When the user exposes or covers the controller 310, only a simple flipping action is required, and the operation is relatively convenient.

[0090] Please refer to Figures 7 to 8, Further, the first decorative plate 135 or the panel 111 is provided with a clamping portion 1354, and the clamping portion 1354 is detachably connected to the pivot 1376. Among them, the clamping portion 1354 can clamp the pivot 1376 to rotate around the pivot 1376. With such a setting, the clamping portion 1354 can rotate around the pivot 1376 while clamping the pivot 1376, so that the first decorative plate 135 can expose or cover the exposure opening 137a. Moreover, with the detachable setting between the clamping portion 1354 and the pivot 1376, the first decorative plate 135 can be disassembled and assembled, which is convenient for maintaining the first decorative plate 135 or replacing the first decorative plate 135 of the required style, providing more options for the user.

[0091] Please refer to Figures 7 to 8 , The second decorative plate 137 or the panel 111 is provided with a fixed seat 1377, the pivot 1376 passes through the fixed seat 1377, and the fixed seat 1377 is provided with an avoidance space 1377a for avoiding the clamping portion 1354. In this way, through the setting of the avoidance space 1377a, it is avoided that the clamping portion 1354 interferes with the fixed seat 1377 during the rotation process, so that the rotatable range of the clamping portion 1354 is larger, and further the flipping range of the first decorative plate 135 is larger, so as to avoid blocking the exposure opening 137a relative to the second decorative plate 137 and also making it more convenient for the user to operate the controller 310.

[0092] Please refer to Figures 7 to 8 , In some structural forms, the second decorative plate 137 or the panel 111 is provided with either a connection buckle 1355 or a connection groove 1378, and the first decorative plate 135 is provided with the other of the connection buckle 1355 and the connection groove 1378. Among them, the connection buckle 1355 is buckled into the connection groove 1378.

[0093] In this way, when the first decorative plate 13 covers the exposure opening 137a, the relative fixation between the first decorative plate 13 and the second decorative plate 137 or the panel 111 can be realized through the buckling cooperation of the connection buckle 1355 and the connection groove 1378, improving the stability. And when the first decorative plate 13 needs to open the exposure opening 137a, the connection buckle 1355 can also be deformed to disengage from the connection buckle 1355, which is convenient and fast to operate. It can be understood that it can be that the second decorative plate 137 or the panel 111 is provided with the connection buckle 1355 and the first decorative plate 135 is provided with the connection groove 1378, or it can be that the second decorative plate 137 or the panel 111 is provided with the connection groove 1378 and the first decorative plate 135 is provided with the connection buckle 1355. The embodiments of the present application do not limit this.

[0094] Of course, in addition to the fastening form of connecting the connecting buckle 1355 and the connecting groove 1378, it is also possible that the second decorative plate 137 or the panel 111 is provided with a first magnetic member, and the first decorative plate 135 is provided with a second magnetic member that magnetically attracts the first magnetic member. 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 exposed opening 137a through magnetic attraction cooperation.

[0095] Please refer to Figures 4 to 5 , in some embodiments, the panel assembly 11 may 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-shaped, the plurality of first mounting portions 115 and the plurality of second mounting portions 117 may be arranged at intervals along the circumferential direction of the panel assembly 11, or may be arranged at intervals along the length direction or the width direction of the panel assembly 11. The embodiments of the present application do not limit this. Correspondingly, the decorative plate group 13 may be provided with a plurality of first connection portions 131 and a plurality of second connection portions 133. Among them, a first connection portion 131 is snap-connected to a first mounting portion 115, and a second connection portion 133 is connected to a second mounting portion 117 through a connecting member (not shown in the figure).

[0096] In some structural forms of the first connection portion 131 and the first mounting portion 115, the first connection portion 131 may be a buckle 1311, and the first mounting portion 115 may be a slot, so as to realize the snap-fit of the first connection portion 131 and the first mounting portion 115; of course, in other structural forms, the first connection portion 131 may be a slot, and the first mounting portion 115 may be a buckle 1311. The embodiments of the present application do not limit this.

[0097] In some structural forms of the second connection portion 133 and the second mounting portion 117, the second connection portion 133 may be a threaded post 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 connection portion 133 may be connected through the threaded member; of course, in other structural forms, the second connection portion 133 may be a mounting hole 117a, and the second mounting portion 117 may be a threaded post 1331. In addition, it is also possible that both the second connection portion 133 and the second mounting portion 117 are mounting holes 117a, and the connecting member may be in the form of a rivet, a screw, a bolt, etc., and then pass through the second connection portion 133 and the second mounting portion 117 to achieve connection. The embodiments of the present application do not limit this.

[0098] 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 panel group 13, and simultaneously snap - connecting the first connecting portion 131 and the first mounting portion 115, and connecting the second connecting portion 133 and the second mounting portion 117 through a connecting member, the panel structure 100 of this embodiment has three aspects of effects:

[0099] First, in terms of connection stability, since on the basis of the snap - connection setting between the first connecting portion 131 and the first mounting portion 115, the connection between the second connecting portion 133 and the second mounting portion 117 is added. In this way, even if the first connecting portion 131 (which is the snap 1311) or the first mounting portion 115 undergoes structural deformation, fracture, etc. during long - term use, resulting in connection failure, the panel structure 100 of this embodiment can still achieve the stable connection between the panel assembly 11 and the decorative panel group 13 through the second connecting portion 133 and the second mounting portion 117, thereby improving the structural stability of the panel structure 100.

[0100] Second, in terms of assembly efficiency, during the actual assembly process, the panel structure 100 of this embodiment can achieve the pre - fixed connection between the panel assembly 11 and the decorative panel group 13 through the snap - connection between the first connecting portion 131 and the first mounting portion 115. On this basis, through the connection between the second connecting portion 133 and the second mounting portion 117 using the connecting member, the final connection between the panel assembly 11 and the decorative panel group 13 is achieved. In this way, through the pre - fixed connection, the accuracy of the relative positions between the panel assembly 11 and the decorative panel group 13 can be ensured, avoiding position errors of the second connecting portion 133 and the second mounting portion 117 during the subsequent assembly process, and effectively improving the assembly efficiency and assembly accuracy of the panel assembly 11 and the decorative panel group 13.

[0101] Third, in terms of sealing effect, 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 correspondingly providing a plurality of first connecting portions 131 that are snap - connected to the first mounting portions 115 and a plurality of second connecting portions 133 that are connected to the second mounting portions 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 opposite surfaces between the panel assembly 11 and the decorative panel group 13 are closer, effectively reducing the size of the gap between the opposite surfaces of the panel assembly 11 and the decorative panel group 13, and reducing the possibility of dust, water, or other impurities entering through this gap, thereby reducing the possibility of the controller 310 being affected by dust, water, or other impurities.

[0102] Please refer to Figures 4 to 6, in some embodiments, the first mounting portion 115 may be the above-mentioned card slot, and specifically may include a first chute 115a and a second chute 115b provided on the panel assembly 11. The first chute 115a and the second chute 115b are communicated, and the opening of the first chute 115a is larger than that of the second chute 115b. The first connecting portion 131 may include a buckle 1311, and the buckle 1311 can be snapped into the second chute 115b along the first chute 115a and partially abuts against the surface of the panel assembly 11 facing away from the decorative panel group 13.

[0103] Among them, the buckle 1311 has a root portion and a hook portion that are connected in a substantially L shape. During actual use, the buckle 1311 can be first inserted into the first chute 115a. At this time, both the root portion and the hook portion of the buckle 1311 can pass through the first chute 115a. Then, the buckle 1311 is slid along the first chute 115a in the direction of the second chute 115b to be snapped into the second chute 115b. During this process, the root portion of the buckle 1311 will not be deformed due to the interference of the wall surface of the first chute 115a and the wall surface of the second chute 115b. And finally, the hook portion of the buckle 1311 can abut against the surface of the panel assembly 11 facing away from the decorative panel group 13 to achieve clamping. And during the process of disconnecting, that is, when the buckle 1311 slides from the second chute 115b to the first chute 115a and the buckle 1311 is disengaged from the first chute 115a, the buckle 1311 will not be deformed due to the interference of the wall surface of the second chute 115b and the wall surface of the first chute 115a. Thus, compared with the form that the buckle 1311 is snapped into or disengaged from the card slot by its own deformation, the embodiment of the present application can avoid the buckle 1311 being damaged due to multiple deformations, so that the service life of the buckle 1311 can be effectively prolonged.

[0104] In some structural forms, the buckle 1311 and the decorative panel group 13 may be an integral structure, so that the connection strength between the two can be improved and the assembly steps for the two can be reduced; of course, in other structural forms, the buckle 1311 and the decorative panel group 13 may be a split structure. Thus, under long-term use, the service life of the decorative panel group 13 can be prolonged by replacing the damaged buckle 1311. The embodiment of the present application does not limit this.

[0105] Further, the buckle 1311 can be disposed on the side of the decorative panel group 13 facing the panel assembly 11. In this way, the buckle 1311 can be blocked by the decorative panel group 13 to achieve a hidden effect of the buckle 1311. Thus, when the user views the panel structure 100 from the outside, the buckle 1311 cannot be seen, and the decorative panel assembly 11 also blocks the first mounting portion 115, thereby effectively improving the external aesthetics of the panel structure 100. Of course, the buckle 1311 can also be disposed on the circumferential surface of the decorative panel group 13, and the embodiments of the present application do not limit this.

[0106] Please continue 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 post 1331 provided on the side of the decorative panel group 13 facing the panel assembly 11. The second mounting portion 117 and the second connecting portion 133 are connected by a threaded member. It can be understood that the threaded post 1331 can be internally formed with internal threads, and the threaded member has external threads. The threaded member passes through the mounting opening 111a and then passes through the threaded post 1331 to achieve the connection between the threaded member and the threaded post 1331 through the cooperation of the external threads and the internal threads.

[0107] In this way, during the installation process, compared with 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 group 13 and then is threadedly connected with the threaded member through a nut, the embodiments of the present application do not require the operation steps of passing the threaded member through the two mounting holes 117a and tightening the nut. Thus, the installation efficiency can be improved. Moreover, the form in which the threaded post 1331 is directly provided on the decorative panel group 13 can improve the bearing capacity of the threaded post 1331 on the panel assembly 11 by the decorative panel group 13. At the same time, it is not necessary to provide a mounting hole 117a in the decorative panel group 13, thereby improving the external aesthetics of the decorative panel group 13 and avoiding the exposure of the threaded member. In addition, when the threaded post 1331 is disposed on the side of the decorative panel group 13 facing the panel assembly 11, the threaded post 1331 can be blocked by the decorative panel group 13 to achieve a hidden effect of the threaded post 1331.

[0108] Please continue to refer to Figures 4 to 6, in some structural forms, there are multiple first connecting parts 131 arranged at intervals along the periphery of the decorative panel group 13, and there are multiple second connecting parts 133 arranged at intervals along the periphery of the decorative panel group 13. With such an arrangement, when the multiple first connecting parts 131 are respectively and fixedly pre-connected with the multiple first mounting parts 115, the decorative panel assembly 11 is aligned with the panel assembly 11 through its peripheral part, so that the overall alignment accuracy between the decorative panel assembly 11 and the panel assembly 11 can be improved. Moreover, through the cooperation between the multiple first connecting parts 131 and the multiple second connecting parts 133, the panel assembly 11 and the decorative panel group 13 can be tightly connected in the circumferential direction, effectively improving the connection stability between the panel assembly 11 and the decorative panel group 13 and the sealing effect on the gap between the panel assembly 11 and the decorative panel group 13.

[0109] In order to further improve the connection stability between the panel assembly 11 and the decorative panel group 13, please continue to refer to Figures 4 to 6 , further, the decorative panel group 13 is provided with an exposed area for corresponding to the controller 310, wherein at least one second connecting part 133 is arranged adjacent to the exposed area for connecting in cooperation with the second connecting part 133. With such an arrangement, while the panel assembly 11 of the embodiment of the present application realizes the circumferential connection of the decorative panel group 13, the part of the panel assembly 11 adjacent to its mounting opening 111a will also be connected to the decorative panel group 13. Thus, the connection area between the panel assembly 11 and the decorative panel group 13 can be increased, thereby improving the connection stability between the two. At the same time, the effect that both the peripheral part and the part close to the center of the decorative panel group 13 are connected to the panel assembly 11 can be achieved. While improving the connection stability, the panel assembly 11 and the decorative panel group 13 can be made to be more tightly attached, and further reducing the possibility of impurities flowing in from the gap formed between the panel assembly 11 and the decorative panel group 13.

[0110] Exemplarily, at least two second connecting parts 133 are arranged adjacent to the exposed area, and the two second connecting parts 133 are symmetrically arranged on both sides of the exposed area, so as to improve the connection stability between the panel assembly 11 and the decorative panel group 13 and the sealing effect on the gap.

[0111] Further, the first mounting portion 115 may be arranged on the panel 111, while the second mounting portion 117 is arranged on the mounting bracket 113, and the panel 111 is provided with an avoidance opening 111b corresponding to the second connection portion 133. It is understandable that, under the stress condition of the panel assembly 11, the second mounting portion 117 connected to the second connection portion 133 is the main stress point, and the first mounting portion 115 connected to the first connection portion 131 as a pre-fixed clamping form is the secondary stress point. In this way, the mounting bracket 113 can be used as the main stress bearing member, and the panel 111 can be used as the secondary stress bearing member, so that the force dispersion is more reasonable, and the effect of step stress is achieved, thereby reducing the possibility of deformation of the panel 111 as an appearance part due to excessive stress. Of course, in other structural forms, the first mounting portion 115 can also be arranged on the mounting bracket 113, and the second mounting portion 117 can be arranged on the panel 111, and the embodiment of the present application is not limited to this.

[0112] It is understandable that when the first mounting portion 115 is in the form of a slot and is directly engaged with 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.

[0113] In the case where 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 arranged 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 the threaded column 1331 can slide, thereby avoiding the interference between the threaded column 1331 and the panel 111 during the sliding process of the buckle 1311.

[0114] Optionally, the threaded column 1331 may include a column body and a step portion, wherein the step portion is connected to the side of the mounting bracket 113 of the decorative panel group 13 facing the panel assembly 11, and the column body is connected to the side of the step portion away from the decorative panel group 13, and is connected to the second mounting portion 117 by a threaded member, wherein the step portion can be slidably disposed in 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.

[0115] Among them, it is possible that both the first connecting portion 131 and the second connecting portion 133 are provided on the first decorative plate 135. In this way, it is possible to prevent the second decorative plate 137 from being connected to the panel 111 and the mounting bracket 113 of the panel assembly 11 and deforming due to stress, thereby ensuring the durability and external aesthetics of the second decorative plate 137. It is also possible that both the first connecting portion 131 and the second connecting portion 133 are provided on the second decorative plate 137. In this way, it is possible to prevent the first decorative plate 135 from being connected to the panel 111 and the mounting bracket 113 of the panel assembly 11 and deforming due to stress, thereby ensuring the durability and external aesthetics of the first decorative plate 135. It is also possible that the first connecting portion 131 is provided on the second decorative plate 137 and the second connecting portion 133 is provided on the first decorative plate 135. In this way, the first connecting portion 131 and the second connecting portion 133 are respectively used to connect to the panel 111 and the mounting bracket 113 of the panel assembly 11 to evenly distribute the force, and the first connecting portion 131 serving as the buckle 1311 is provided on the second decorative plate 137 which mainly plays a decorative effect. In this way, it is possible to prevent the second decorative plate 137 from deforming due to excessive stress. Of course, it is also possible that the first connecting portion 131 is provided on the first decorative plate 135 and the second connecting portion 133 is provided on the second decorative plate 137.
