[0042] The technical solution of this invention will be further described below with reference to the accompanying drawings and through specific implementation methods. It should be understood that the specific embodiments described herein are only used to explain this invention, rather than to limit this invention.

[0043] In one embodiment of the present application, Figures 1 to 8 As shown, a ceiling assembly 10 is provided. The ceiling assembly 10 may include a hanging piece 101 and a connecting piece 102. The hanging piece 101 and the connecting piece 102 may both be made of metal, such as steel or aluminum alloy. The hanging piece 101 may be formed by stamping or extrusion. Figure 1 As shown in FIG, the hanging direction of the ceiling assembly 10 is marked as Z direction. Figure 1 As shown, the hanging member 101 may include a hanging rod 103 and a main body 104. The cross-sectional shape of the hanging rod 103 perpendicular to its axis may be circular, elliptical, or rectangular, etc. The axial direction of the hanging rod 103 is parallel to the Z direction. The end of the hanging rod 103 away from the main body 104 may be provided with a hanging installation point 105 for mounting the ceiling assembly 10. For example, the hanging installation point 105 may be a portion of the hanging rod 103, etc.

[0044] In some exemplary embodiments, Figure 1As shown, the suspension rod 103 and the main body 104 can be connected by screw connection or welding, etc. The present disclosure does not limit the connection method between the suspension rod 103 and the main body 104.

[0045] In some exemplary embodiments, Figure 1 As shown, the hanging member 101 may include a hanging portion 106. The hanging portion 106 is used to realize the hanging connection between the connecting member 102 and the hanging member 101. The hanging portion 106 may be as follows Figure 1 、 Figure 2 Hook shown.

[0046] In some exemplary embodiments, Figure 7 、 Figure 8 As shown, the hanging portion 106 may include a bending area 106a. The bending area 106a is used to improve the elasticity of the hanging portion 106, which can improve the vibration reduction performance of the ceiling assembly 10. During actual use, the bending area 106a can absorb horizontal (direction perpendicular to the Z direction) vibration force, which can improve the vibration reduction performance of the entire product. Furthermore, the use of the provided bending area 106a can enable the hanging portion 106 to have appropriate deformation ability, so as to facilitate disassembly and assembly. During the installation process, the bending area 106a can be compressed along the X direction so that the movable matching portion 108 and the hanging portion 106 are hung and matched in place. During the disassembly process, the bending area 106a can be compressed along the X direction so that the movable matching portion 108 and the hanging portion 106 are disengaged.

[0047] In some exemplary embodiments, Figure 2 As shown, the connecting member 102 includes a fixed portion 107 and a movable matching portion 108. The movable matching portion 108 can reciprocate relative to the fixed portion 107 along the X direction. The movable matching portion 108 is configured to move between a first position and a second position relative to the fixed portion 107. Figure 2 As shown, in the structure where the movable matching portion 108 is in the first position, the movable matching portion 108 and the hook portion 106 are in a disengaged state, as shown in FIG. Figure 2 In the structure where the movable matching portion 108 is in the second position, the movable matching portion 108 and the hooking portion 106 are in a hooking state, as shown in FIG. Figure 2 Shown as the solid line part.

[0048] like Figure 2 As shown, the fixing portion 107 may be provided with a first mounting surface 109 for contacting and cooperating with the ceiling unit 20. The ceiling unit 20 may be fixed to the first mounting surface 109 of the fixing portion 107 by bonding, screwing, or clamping. For example, the fixing portion 107 may also be provided with a second mounting surface 110, such as Figure 2As shown, in the plane defined by XZ, the first mounting surface 109 and the second mounting surface 110 can be perpendicular. During the installation of the ceiling unit 20 to the fixing portion 107, the second mounting surface 110 can serve as a limiter and a protector, thereby improving installation efficiency and ensuring quality.

[0049] During actual use of the ceiling assembly 10, the component to be installed (e.g., the ceiling unit 20) can be first installed on the fixed portion 107, and then the movable fitting portion 108 is moved to the first position. The component to be installed is then lifted upward along the Z direction. The movable fitting portion 108 is then moved to the second position so that the movable fitting portion 108 and the hanging portion 106 are opposite in the Z direction. The lifting of the component to be installed is then removed, and the component to be installed moves downward along the Z direction under the action of its own weight until the movable fitting portion 108 and the hanging portion 106 are hooked together, thereby completing the assembly of the component to be installed with the ceiling assembly 10. During the disassembly process, an upward lifting force along the Z direction is applied to the component to be installed, and then the movable fitting portion 108 is moved from the second position to the first position so that the movable fitting portion 108 and the hanging portion 106 are disengaged, thereby completing the assembly and disassembly of the component to be installed.

[0050] The ceiling assembly provided in the embodiment of the present application is provided with a movable matching part, so that the movable matching part can switch back and forth between a first position and a second position relative to the fixed part, so that when the movable matching part is in the first position, the movable matching part and the hanging part are both in a disengaged state, and when the movable matching part is in the second position, the movable matching part and the hanging part are in a hanging state, so as to facilitate the disassembly and assembly between the components to be installed and the ceiling assembly, improve the efficiency of the disassembly and assembly operation, realize the hidden arrangement of the installation structure and facilitate the subsequent modification and maintenance, thereby improving the overall appearance.

[0051] In some exemplary embodiments, Figure 3 As shown, the fixed portion 107 includes a fixed slide rail provided with a slide groove 111, and the movable matching portion 108 includes a matching portion 112 that slides with the slide groove 111. The fixed slide rail may also be provided with a first limit point (not shown in the figure) and a second limit point (not shown in the figure), so that the matching portion 112 is at the first limit point to place the movable matching portion 108 in the first position, and the matching portion 112 is at the second limit point to place the movable matching portion 108 in the second position. The first limit point may be a convex feature stamped out of the fixed slide rail, or a baffle that is manufactured separately and then installed on the fixed slide rail. The present disclosure does not limit the specific design structure of the first limit point and the second limit point. Figure 3 The figure only illustrates a cross-sectional shape of the matching portion 112. The cross-sectional shape of the matching portion 112 may be an I-shaped or a F-shaped shape.

[0052] In some exemplary embodiments, Figure 1 、 Figure 2、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 As shown, the main body 104 is provided with a receiving space. Figure 1 As shown, within the plane defined by XZ, the accommodation space can be rectangular or similar in shape. This accommodation space can be used to install electrical components, such as decorative lights, and can also serve as an air vent for the ceiling assembly unit, greatly improving the integration and aesthetics of the ceiling assembly unit. The main portion 104 can serve solely as a support structure for the ceiling assembly 10, but can also serve as a structure for architectural lighting fixtures and air vents, depending on the functional requirements and aesthetics of the ceiling. This enables integrated ceiling decoration design and construction. The cross-sectional dimensions of the main portion 104 can be adjusted according to these functional requirements.

[0053] by Figure 2 As shown in the example, the main body 104 includes a first end face 104a and a second end face 104b that are arranged opposite to each other along the hanging direction (Z) of the ceiling assembly 10. The second end face 104b is farther away from the hanging installation point 105 of the ceiling assembly 10 than the first end face 104a. Figure 2 、 Figure 6 as well as Figure 8 As shown, there is a height difference between the second end surface 104b and the first mounting surface 109 along the hanging direction (Z direction) of the ceiling assembly 10. For example, along the Z direction, the second end surface 104b can be located between the hanging installation point 105 and the first mounting surface 109. Alternatively, along the Z direction, the first mounting surface 109 can be located between the hanging installation point 105 and the second end surface 104b.

[0054] like Figure 1 、 Figure 5 、 Figure 7 As shown, after the ceiling unit 20 and the ceiling assembly 10 are assembled in place, the main body 104 of the ceiling assembly 10 and the ceiling unit 20 can be combined into different forms, which can enhance product diversity.

[0055] In some exemplary embodiments, Figure 4 As shown, the main body 104 may be provided with a first operating opening 113 and a second operating opening 114. For example, the first operating opening 113 may be a circular hole or a rectangular hole. For example, the first operating opening 113 may be a strip-shaped notch. The shape and size of the second operating opening 114 may be the same as or different from the first operating opening 113, and this disclosure is not limited thereto. During the manufacturing process, the first operating opening 113 may be formed by stamping or bending a sheet material.

[0056] like Figure 4As shown, the first operation port 113 and the second operation port 114 are connected via the accommodation space. The first operation port 113 can be located on the second end surface 104b. The second operation port 114 can be located above or below the hanging portion 106. Figure 4 As shown, for example, the second operating opening 114 may be located on a side of the hanging portion 106 away from the first mounting surface 109. The second operating opening 114 may expose at least a portion of the movable fitting portion 108 to facilitate the moving operation of the movable fitting portion 108.

[0057] During the process of disassembling and assembling the suspended ceiling assembly 10, the worker's hand can enter the accommodating space through the first operating port 113, and then extend it from the second operating port 114 to move the movable matching part 108, so that the movable matching part 108 can be switched back and forth between the first position and the second position relative to the fixed part 107, so as to disassemble and assemble the component to be installed (for example, the component to be installed can be the ceiling unit 20).

[0058] In some exemplary embodiments, Figure 4 As shown, the second operating port 114 and the hanging portion 106 can be an integrally formed structure. For example, the hanging portion 106 and the second operating port 114 can be obtained through the same forming process using a stamping process. During the stamping process, the sheet metal can be cut first. For example, the cutting line can be U-shaped, and the cut sheet metal is stamped to obtain the second operating port 114 and the hanging portion 106 through the same process. The hanging portion 106 and the second operating port 114 are integrally formed after stamping. When the hanging portion 106 is bent into an oblique upward hanging hook shape, its root can be bent into a certain arc, not a dead bend, which is conducive to hanging and bearing.

[0059] In some exemplary embodiments, Figure 4 As shown, the main body 104 further defines a third operating opening 115. The third operating opening 115 and the second operating opening 114 are both located on the same side of the ceiling assembly 10 in the hanging direction (Z direction). The third operating opening 115 may be located between the hanging portion 106 and the first mounting surface 109.

[0060] In some exemplary embodiments, Figure 4 As shown, the main body 104 may also be provided with a bent portion 117. The bent portion 117 may be integrally formed with the third operating opening 115. For example, the bent portion 117 and the third operating opening 115 may be formed in a single forming process using a stamping process. During the stamping process, the sheet metal may be first cut, for example, with a U-shaped cut line. The cut sheet metal is then stamped to form the third operating opening 115 and the bent portion 117 in a single process.

[0061] In some exemplary embodiments, the connector 102 may further include an operating portion fixed to the movable fitting portion 108. At least a portion of the operating portion extends in the direction of the main body portion 104. For example, the operating portion may be an operating handle, a push-pull rod, or an operating handball, so that the worker can use the operating portion to apply a force to the movable fitting portion 108 so that the movable fitting portion 108 and the hanging portion 106 are hooked or disengaged from each other. The operating portion may be integrally formed with the movable fitting portion 108, such as integrally stamped or extruded, and the present disclosure does not limit the molding method of the operating portion. At least one of the second operating port 114 and the third operating port 115 exposes at least a portion of the operating portion so that the movable fitting portion 108 can be moved by operating the operating portion.

[0062] In some exemplary embodiments, Figure 2 As shown, the hanging member 101 is a self-symmetrical structure along the hanging direction (Z direction) of the ceiling assembly 10. Figure 2 As shown, the suspension member 101 can be symmetrical along axis A, which is parallel to the Z direction. For example, axis A can coincide with the central axis of the ceiling assembly 10. For example, the ceiling assembly 10 can be a self-symmetrical structure.

[0063] In some exemplary embodiments, Figure 2 As shown, the ceiling assembly 10 may include two connecting members 102, and the two movable engaging portions 108 of the two connecting members 102 may be arranged opposite each other. Correspondingly, the hanging member 101 has two hooking portions 106 arranged opposite each other, and the two movable engaging portions 108 are respectively hooked to the two hooking portions 106, so that two adjacent ceiling units 20 can be hung and installed using a single ceiling assembly 10.

[0064] In some exemplary embodiments, Figure 2 As shown, the size of the accommodation space along the Z direction is marked as H, and the opening size of the first operating port 113 along the X direction is marked as W. H can be larger than W to provide sufficient operating space for the worker's arm to operate the movable matching part 108 through the accommodation space. For example, H can be 1.5W, or H can be 2W, etc. Figure 2 As shown, H is also the distance between the first end surface 104a and the second end surface 104b that are oppositely disposed.

[0065] In some exemplary embodiments, Figure 6As shown, the main body 104 is provided with a mounting flange 116 extending radially and outwardly from the first operating port 113. For example, the mounting flange 116 may be annular in shape. This mounting flange 116 can be used to mount electrical components or decorative parts, such as decorative lights, decorative panels, or air vents. This mounting flange 116 provides mounting support for the component to be secured. The mounting flange 116 can be integrally molded with other structures of the main body 104.

[0066] After the electrical components or decorative components are installed in place, the mounting flange 116 can cover the matching gap between the electrical components or decorative components and the accommodation space to enhance the overall appearance of the product.

[0067] The embodiment of the present application also provides a ceiling assembly unit. The ceiling assembly unit includes the ceiling assembly 10 and the ceiling unit 20 described in any of the above embodiments, such as Figure 1 、 Figure 5 、 Figure 7 As shown. The ceiling unit 20 is mounted to the first mounting surface 109 of the ceiling assembly 10. The connection method can be screwing, clamping, or bonding, etc., and this disclosure does not limit the method of achieving the connection. The connecting member 102 is hung together with the ceiling unit 20 on the hanging member 101.

[0068] In some exemplary embodiments, the ceiling unit 20 may be a gypsum board, a wood panel, a thin aluminum plate, or an assembly of several types of plates.

[0069] In some exemplary embodiments, Figure 1 、 Figure 7 As shown, the ceiling assembly 10 can be located between two adjacent ceiling units 20. A gap 30 is left between two adjacent ceiling units 20. At least a portion of the hanging member 101 is exposed to the gap 30.
