Description

Technical Field

[0001] This application relates to the field of building technology, and more specifically, to a panel back box assembly and a switch panel assembly. Background Technology

[0002] With the rapid development of the construction industry towards industrialization and modularization, prefabricated decoration has been widely applied in residential, commercial, and public buildings due to its advantages such as high construction efficiency, environmental protection and energy saving, and controllable quality. In prefabricated decoration systems, prefabricated wall panels, as core decorative components, need to be installed in conjunction with various functional components (such as switch panels and socket panels) to meet the usage requirements of the building space. Among these, the panel back box, as the core load-bearing component of the switch panel, directly determines the coordination, aesthetics, and safety of the switch panel and wall panel during installation, thus becoming a key technical aspect in the integration process of prefabricated wall systems.

[0003] In existing technologies, panel back boxes typically employ a one-piece molded square structure design, with their dimensions (including height, width, and depth) fixed after manufacturing, making them unadjustable according to the actual installation scenario. During actual construction, workers must first pre-fix the back box to the structural wall, then assemble the prefabricated wall panels on the outside. After the wall panels are in place, the switch panel is embedded into the back box to complete the final assembly. However, in prefabricated wall construction, there is usually a cavity of a certain thickness between the prefabricated wall panels and the structural wall. This cavity is primarily used for laying pipelines and achieving sound insulation and heat preservation. The aforementioned panel back box presents a significant drawback in this application scenario.

[0004] Firstly, because traditional panel boxes are fixed-size integrated structures, once their installation position on the structural wall is determined, the position of the end face of the box facing the wall panel cannot be changed. Furthermore, the cavity thickness between the prefabricated wall panel and the structural wall varies depending on the design requirements of different buildings, inevitably creating a non-adjustable gap between the end face of the box and the inner wall of the wall panel. If this gap is too small, the wall panel is prone to colliding with the box during installation, causing damage to either the wall panel or the box. If the gap is too large, gaps will appear between the switch panel and the wall panel during subsequent installation, affecting aesthetics and easily leading to dust accumulation and moisture penetration, thus shortening the component's lifespan.

[0005] Secondly, during the assembly process, the switch panel needs to be fixed with the back box. The height of its outer surface is directly determined by the installation depth of the back box. However, the prefabricated wall panel has a fixed thickness, and the distance between the outer surface of the wall panel and the end face of the back box cannot be adjusted by the back box itself. As a result, after the switch panel is installed, the outer surface either protrudes from the wall panel or is recessed into the wall panel, and it is always impossible to achieve flush installation between the switch panel and the prefabricated wall panel. Utility Model Content

[0006] In view of the above problems, this application provides a panel back box assembly. The panel back box assembly provided by this application can adapt to different cavity sizes between the wall panel and the wall, and can realize flush installation of the switch panel and the wall panel.

[0007] According to a first aspect of this application, a panel back box assembly is provided, comprising:

[0008] A first housing includes a plurality of first sidewalls, with a receiving portion formed between the plurality of first sidewalls; each first sidewall is provided with a first connector, the first connector being located in the receiving portion, and the length of the first connector being along a first direction;

[0009] The second housing includes a plurality of stepped structures and a plurality of second sidewalls, the second sidewalls extending from the stepped structures toward the first housing, and each second sidewall is provided with a second connector, the length of the second connector being along the first direction;

[0010] The number of the first sidewall, the second sidewall, and the stepped structure are equal, and multiple second sidewalls are located in the receiving part. The first connector and the second connector correspond one-to-one and are slidably connected.

[0011] According to an embodiment of this application, the stepped structure includes a third sidewall and a platform, the third sidewall being parallel to the second sidewall, and one end of the third sidewall being connected to one end of the second sidewall via the platform.

[0012] According to an embodiment of this application, the second housing further includes an end face connected to the other end of the third sidewall, the end face being parallel to the platform and having an extension direction opposite to that of the platform.

[0013] According to an embodiment of this application, the first connector is a guide groove, and the second connector is a plug-in connector.

[0034] The embodiments of this application will now be described with reference to the accompanying drawings. However, it should be understood that these descriptions are exemplary only and are not intended to limit the scope of this application. In the following detailed description, numerous specific details are set forth to provide a thorough understanding of the embodiments of this application for ease of explanation. However, it will be apparent that one or more embodiments may be implemented without these specific details. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concepts of this application.

[0037] When using expressions such as "at least one of A, B and C", they should generally be interpreted in accordance with the meaning that is commonly understood by those skilled in the art (e.g., "a system having at least one of A, B and C" should include, but is not limited to, a system having A alone, a system having B alone, a system having C alone, a system having A and B, a system having A and C, a system having B and C, and / or a system having A, B and C, etc.).

[0038] In related technologies, cavities often exist between wall panels and structural walls, posing challenges to switch panel installation. Traditional panel boxes are mostly fixed square designs, lacking adjustability in size and structure, making it difficult to accommodate wall panels of varying thicknesses and cavities. This results in switch panels not being able to be installed flush with the wall panels, affecting overall aesthetics and user experience. Furthermore, the combination of traditional boxes and prefabricated wall panels is relatively fixed, lacking flexibility and unable to meet the installation needs of wall panels of various sizes and thicknesses, thus limiting the widespread application of prefabricated decoration.

[0039] Embodiments of this application provide a panel bottom box assembly, comprising: a first housing, the first housing including a plurality of first sidewalls forming a receiving portion between the plurality of first sidewalls; a first connector disposed on each first sidewall, the first connector being located in the receiving portion, the length of the first connector being along a first direction; and a second housing, the second housing including a plurality of stepped structures and a plurality of second sidewalls, the second sidewalls extending from the stepped structures toward the first housing, each second sidewall being provided with a second connector, the length of the second connector being along the first direction; wherein the number of first sidewalls, second sidewalls, and stepped structures is equal, the plurality of second sidewalls are located in the receiving portion, and the first connectors and second connectors correspond one-to-one and are slidably connected.

[0040] According to an embodiment of this application, when installing a switch panel using the panel back box assembly provided in this application, the first housing is fixed in the wall, and one side of the second housing is slidably connected to the first housing through the cooperation of the first connector and the second connector, while the other side is tightly fitted to the wall panel surface. Since the distance between the first connector and the second connector is adjustable in the first direction, the size of the panel back box assembly in the first direction is adjustable, thereby adapting to different cavity sizes between the wall panel and the wall. In addition, the side of the second housing that is fitted to the wall panel surface has a stepped structure, and the switch panel is placed in the stepped structure, so that the surface of the switch panel is flush with the surface of the wall panel, achieving flush mounting and improving the aesthetics of the overall structure.

[0041] Figure 1 The schematic diagram illustrates the structure of a panel back box assembly according to an embodiment of this application.

[0042] like Figure 1 As shown, the panel base box assembly includes a first housing 100 and a second housing 200, the second housing 200 being embedded in the first housing 100 and the two being slidably connected.

[0043] Figure 2a and Figure 2b The top view and side view of the first housing according to an embodiment of this application are shown schematically, respectively.

[0044] Combination Figure 2a and Figure 2bAs shown, the first housing 100 includes a plurality of first sidewalls 11 and a bottom surface 12, with a receiving portion 101 formed between the bottom surface 12 and the plurality of first sidewalls 11. In this embodiment, the first housing 100 has four first sidewalls 11, adjacent first sidewalls 11 are vertically connected, and the bottom surface 12 is rectangular, that is, the first housing 100 is a cubic structure with an opening and a hollow interior.

[0045] Combination Figure 1 and Figure 2a As shown, each first sidewall 11 is provided with a first connector 13, the first connector 13 is located in the receiving portion 101, and the length of the first connector 13 is along the first direction ( Figure 1 (As shown in the Z-axis direction), when installing the panel base box assembly, the second housing 200 is embedded in the receiving portion 101, and the first connector 13 is used to connect with the second connector 26 in the first direction (as shown in the Z-axis direction). Figure 1 (Sliding connection in the Z-axis direction shown). In this embodiment, the length of the first connector 13 is equal to the height of the first sidewall 11, thereby allowing the second connector 26 to move within the height range of the first sidewall 11 to adjust the distance between the first housing 100 and the second housing 200.

[0046] like Figure 1 As shown, through holes 14 are provided on both the first sidewall 11 and the bottom surface 12 to allow wires and wire conduits to pass through from different directions as needed, thereby providing a flexible wiring solution to avoid excessive bending or uneven stress on the wires during installation. In this embodiment, as... Figure 2a As shown, four through holes 14 are evenly arranged on the bottom surface 12; Figure 2b As shown, each first sidewall 11 has two through holes 14 arranged on it, and these two through holes 14 are located on both sides of the first connector 13.

[0047] Figure 3a and Figure 3b The top view and side view of the second housing according to an embodiment of this application are shown schematically, respectively.

[0048] like Figure 1 As shown, the second housing 200 includes a plurality of stepped structures 22 and a plurality of second sidewalls 21, with the second sidewalls 21 extending from the stepped structures 22 toward the first housing 100. The number of first sidewalls 11, second sidewalls 21, and stepped structures 22 are equal. In this embodiment, the second housing 200 has four second sidewalls 21, with adjacent second sidewalls 21 being vertically connected; the number of stepped structures 22 is also four, with each of the four stepped structures 22 corresponding to one of the four second sidewalls 21.

[0049] like Figure 3bAs shown, the stepped structure 22 includes a third sidewall 23 and a platform 24. The third sidewall 23 is parallel to the second sidewall 21, and one end of the third sidewall 23 is connected to one end of the second sidewall 21 via the platform 24. In this embodiment, the third sidewall 23 and the platform 24 are perpendicularly connected. It should be noted that "perpendicular" in this embodiment refers to an angle of 90° between them. , This is the error angle, which can be 0°, 5°, 10°, etc., and its specific value can be set according to the actual situation.

[0050] like Figure 3b As shown, the second housing 200 also includes an end face 25, which is connected to the other end of the third sidewall 23. The end face 25 is parallel to the platform 24, and the extension directions of the end face 25 and the platform 24 are opposite.

[0051] In this embodiment, the stepped structure 22 is used to place the switch panel, and the height of the third sidewall 23 is consistent with the thickness of the switch panel, so that the surface of the installed switch panel is flush with the end face 25, achieving flush mounting. It neither protrudes from the wall panel nor is it recessed into the wall panel, ensuring the overall aesthetics of the space. In addition, when installing the panel base box assembly, the cut edge of the wall panel contacts the outer surface of the third sidewall 23, and the end face 25 is tightly fitted to the surface of the wall panel. The end face 25 can cover the cut edge of the wall panel, which can not only prevent the cut edge from being exposed and affecting the aesthetics, but also prevent the cut edge from scratching hands or aging and discoloring due to long-term exposure, ensuring the overall aesthetics and safety of use after installation.

[0052] Combination Figure 1 and Figure 3a As shown, each second sidewall 22 is provided with a second connector 26, the length of the second connector 26 being along the first direction ( Figure 1 (As shown in the Z-axis direction), when installing the panel base box assembly, the second housing 200 is embedded in the receiving portion 101, and the first connector 13 and the second connector 26 correspond one-to-one and are in the first direction ( Figure 1 (Sliding connection in the Z-axis direction shown). In this embodiment, the length of the second connector 26 is equal to the length of the first connector 13, thereby allowing the second connector 26 to move within the height range of the first sidewall 11 to adjust the distance between the first housing 100 and the second housing 200.

[0053] In this embodiment, the first connector 13 is a guide groove, and the second connector 26 is a plug-in connector. The second connector 26 is plugged into the first connector 13, enabling a sliding connection between the two. In other optional embodiments, the first connector 13 can be a plug-in connector, and the second connector 26 can be a guide groove, which can also achieve a sliding connection. The first connector 13 and the second connector 26 can also have other structural forms, as long as they can achieve a sliding connection, and there are no restrictions here.

[0054] like Figure 3a As shown, a fixing hole 27 is also provided on the second sidewall 21, located on the back of the second connector 26. When installing the switch panel, a fastener passes through the fixing hole 27 to securely connect the switch panel to the second housing 200. As an example, the fastener can be a screw, pneumatic nail, or other component that provides a fixing function.

[0055] Based on the aforementioned panel back box assembly, this application also provides a switch panel assembly. The following will be combined with... Figure 4a and Figure 4b The switch panel assembly is described in detail.

[0056] Figure 4a and Figure 4b The front view and cross-sectional view of the switch panel assembly according to an embodiment of this application are shown schematically.

[0057] like Figure 4b As shown, the switch panel assembly includes a switch panel 300 and the panel back box assembly described above.

[0058] According to an embodiment of this application, a first housing 100 is embedded in a wall 400, and a second housing 200 is connected to the first housing 100 via a first connector 13 and a second connector 26. Specifically, the second connector 26 is partially inserted into the first connector 13, and the end face 25 of the second housing 200 is tightly fitted to the wall panel 500. Since the first connector 13 and the second connector 26 are slidably connected, the panel bottom box assembly can be adjusted in the first direction by adjusting the portion of the second connector 26 inserted into the first connector 13. Figure 4b The dimensions along the Z-axis (as shown) allow it to accommodate different cavity sizes between the wall 400 and the wall panel 500, improving the adaptability of the panel back box assembly and enhancing the stability of the switch panel assembly.

[0059] According to the embodiments of this application, the switch panel 300 is installed in the stepped structure 22, and the switch panel 300 is flush with the end face 25, so that the switch panel 300 is flush with the wall panel 500. This can avoid the exposed cut edge from affecting the appearance, and also prevent the cut edge from scratching the hand or aging and discoloring due to long-term exposure, ensuring the overall aesthetics and safety of use after installation.
