Description

Technical Field

[0001] This invention belongs to the field of background wall technology, specifically a modular TV background wall that can be disassembled and reassembled. Background Technology

[0002] As a core visual element of interior space, the TV background wall, introduced from public buildings into home design, has become an important medium for enhancing the aesthetics and functional integration of living spaces. Current technologies primarily achieve this through three methods:

[0003] Wet installation uses cement mortar to fix tiles or stone, forming a permanent finish; on-site molding involves cutting and splicing gypsum board and then applying a decorative layer to achieve customized shapes; and integrated fixed installation utilizes wooden boards to rigidly connect to the wall, integrating concealed wiring functions.

[0004] While this type of technology can meet basic decorative needs, it has the following drawbacks:

[0005] 1. Installation and dismantling costs are high, relying on professional construction personnel to carry out complex processes such as cutting, positioning, and bonding. The average construction period is 3-5 days, resulting in excessively high labor costs.

[0006] 2. Fixed installations can cause wall damage during removal, such as peeling of the adhesive layer and anchor holes. Renovation requires secondary repairs, generating construction waste and additional costs.

[0007] 3. The overall structure cannot be adapted to changes in TV size or style upgrades, requiring users to disassemble and replace the entire structure, resulting in a waste of resources.

[0008] At its core, the fundamental contradiction of existing technologies lies in the irreconcilable conflict between "fixed installation" and "dynamic home needs": traditional processes achieve structural stability through physical bonding / nail fastening, but at the expense of reconfigurability. Although modular concepts such as snap-on decorative panels have emerged in recent years, problems such as tool dependence, loose connectors, and insufficient interface standardization still exist, failing to achieve truly user-controlled, non-destructive disassembly and assembly. Summary of the Invention

[0009] The purpose of this invention is to provide a modular TV background wall that can be disassembled and reassembled without the need for overall fixing and with low installation and disassembly costs.

[0010] The modular TV background wall provided by this invention includes multiple wall panels, each wall panel having a connection structure. The connection structure includes a movable plug-in element and an operable locking element. The plug-in element can extend to insert into the plug-in slot of an adjacent wall panel or retract to disengage. The locking element automatically locks the connection when the plug-in element is inserted into the plug-in slot and can be operablely unlocked to retract the plug-in element, thereby realizing the non-destructive disassembly and reassembly of the wall panels.

[0011] In one embodiment of the aforementioned background wall, the plug-in element includes a sliding plate and a plug-in plate fixed on the sliding plate. The sliding plate is slidably disposed in the sliding cavity of the wall panel, and the side wall of the sliding cavity has an extension opening. The plug-in plate extends or retracts through the extension opening.

[0012] In one embodiment of the aforementioned background wall, the sliding cavity is provided with multiple limiting slide rods, and the sliding plate is slidably connected to the limiting slide rods.

[0013] In one embodiment of the aforementioned background wall, a transmission mechanism is further included. The transmission mechanism includes a screw that is threadedly connected to the sliding plate. The transmission mechanism is disposed in a control cavity adjacent to the sliding cavity.

[0014] In one embodiment of the aforementioned background wall, the transmission mechanism further includes a first actuating element, which is an actuating circular plate. The actuating circular plate is rotatably disposed in a circular groove on the upper surface of the wall panel and connected to a bevel gear through a rotating rod. The bevel gear is meshed with a bevel gear, which is fixed to a connecting rod. The connecting rod drives the screw to rotate. An actuating circular hole is provided on the actuating circular plate.

[0015] In one embodiment of the aforementioned background wall, the locking element includes a wedge block and a locking slot, the locking slot being opened on the surface of the plug-in plate, and the wedge block being movably configured to engage or disengage from the locking slot.

[0016] In one embodiment of the aforementioned background wall, the wedge block is fixed to a movable plate, the movable plate is slidably disposed in the extrusion chamber and connected to a return spring; an extension opening is provided between the extrusion chamber and the insertion slot, and the wedge block extends out through the extension opening.

[0017] In one embodiment of the aforementioned background wall, an unlocking mechanism is further included. The unlocking mechanism includes a rotating column and a second actuating element. The second actuating element is a second actuating circular plate, which is slidably disposed in a circular groove on the upper surface of the wall panel and fixedly connected to the rotating column. The rotating column is rotatably disposed in a cylindrical cavity, and its side wall has an annular groove. A limiting block is fixed to the movable plate, and the limiting block passes through the connecting groove and is engaged in the annular groove. An actuating circular hole is provided on the second actuating circular plate.

[0018] In one embodiment of the aforementioned background wall, the insertion slots are located at the top and bottom right sides of the wall panel, and the sliding cavity is located inside the left side of the wall panel.

[0019] The beneficial effects of this invention are as follows:

[0020] 1. By moving the circular plate, the first bevel gear, the second bevel gear, and the screw, the rotational motion is converted into the horizontal displacement of the sliding plate, which drives the plug-in plate to extend or retract. No tools or professional personnel are required. The wall panels can be connected and separated by simply moving the fingers. This eliminates the need for on-site cutting, pasting, or destructive removal, significantly shortening the construction cycle, avoiding construction waste and wall damage, and reducing the cost of initial installation and renovation.

[0021] 2. The wedge blocks, driven by a return spring, automatically engage with the locking slots. Combined with the second actuating plate, the rotating column and limit block synchronously control all wedge blocks to disengage. After insertion, a mechanical self-locking mechanism is formed to resist daily vibration and prevent loosening. During disassembly, all locking points can be unlocked in a single operation to avoid misalignment or jamming. The wall panels can be disassembled repeatedly without damage, improving safety and durability. At the same time, there are no restrictions on the order of operation, enhancing the flexibility of use.

[0022] 3. Each wall panel has a built-in standardized plug-in slot, plug-in plate and control components, and the component universality is ensured by limit slide rods; the number of wall panels can be increased or decreased or the arrangement can be adjusted to adapt to changes in TV size or style updates, without the need to replace the entire background wall; all interfaces are compatible with wall panels of different materials and sizes, reducing material waste and lowering long-term use costs.

[0030] The relevant technical solutions will now be clearly and completely described with reference to the accompanying drawings of the embodiments of the present invention. The described embodiments are only a part of the embodiments, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] like Figure 1 and Figure 2 As shown, the modular TV background wall disclosed in this embodiment is composed of multiple standardized wall panels 1. Each wall panel adopts a modular design and achieves rapid assembly and disassembly through a built-in connection structure.

[0032] like Figure 3 As shown, the top and bottom right sides of the wall panel 1 are provided with insertion grooves 2, and the left side interior forms a sliding cavity 3. The top and bottom left sides of the sliding cavity are provided with protrusions 4.

[0033] A vertical sliding plate 5 is slidably connected inside the sliding cavity 3. A plug-in plate 6 is fixedly connected to the top and bottom left sides of the sliding plate, and the plug-in plate extends into the protrusion 4. Multiple horizontal limiting slide rods 29 are also provided inside the sliding cavity. The limiting slide rods are slidably connected to the sliding plate to ensure that the sliding plate 5 moves horizontally without deviation.

[0034] A control cavity 7 is provided on the right side of the sliding cavity 3. The sliding plate 5 is threadedly connected to the screw 8. The left end of the screw is rotatably connected to the left side wall of the sliding cavity through a rotating shaft, and the right end extends into the control cavity.

[0035] A circular groove 9 is formed on the upper surface of the wall panel 1, and a rotatable actuating circular plate 10 is connected inside the groove. A rotating rod 11 is fixedly connected to the lower surface of the actuating circular plate 1, and the bottom end of the rotating rod extends into the control cavity 7 and is fixedly connected to a bevel gear 12.

[0036] like Figure 4As shown, a connecting rod 13 is rotatably connected to the control cavity 7 via a rotating shaft. The connecting rod is fixedly connected to the screw 8, and a second bevel gear 14 is fixedly connected to the connecting rod 13. The first bevel gear 12 and the second bevel gear 14 mesh with each other to form a gear transmission mechanism.

[0037] The rotary disc 10 has a rotary hole 30 for easy finger operation.

[0038] The upper and lower surfaces of the plug-in plate 6 are provided with locking slots 15.

[0039] like Figure 5 As shown, the wall panel 1 has extrusion chambers 16 located above and below the two insertion slots 2, with a movable plate 17 slidably connected inside the extrusion chambers. An extension opening 18 is provided between the extrusion chambers and the insertion slots. A wedge block 19 is fixedly connected to the movable plate near the insertion slots, passing through the extension opening 18. A return spring 20 is fixedly connected between the movable plate away from the extension opening 18 and the inner wall of the extrusion chamber 16, providing elastic return force.

[0040] like Figure 6 As shown, there is an integrally formed cylindrical cavity 21 inside the wall panel 1 located on the left side of the insertion slot 2. The cylindrical cavity is rotatably connected to the rotating column 22 via a rotating shaft. The two rotating columns are fixedly connected to the opposite sides of the support rod 28 to achieve synchronous rotation. An annular groove 23 is provided on the side wall of the rotating column.

[0041] A circular groove 26 is formed on the upper surface of the wall panel 1 above the cylindrical cavity 21. A movable circular plate 27 is slidably connected in the circular groove 2. The upper end of the rotating column 22 is fixedly connected to the lower surface of the movable circular plate 2. A movable circular hole 30 is formed on the upper surface of the movable circular plate 2 for easy operation.

[0042] A connecting groove 24 is provided between each extrusion chamber 16 and the cylindrical cavity 21. A limiting block 25 is fixedly connected to the left side of the movable plate 17. The limiting block passes through the connecting groove and is slidably engaged in the annular groove 23.

[0043] The purpose of this background wall is to enable quick connection, locking, and non-destructive disassembly of wall panel 1. This is achieved based on a mechanical transmission and self-locking mechanism:

[0044] Manually moving the rotating disc 10 drives the screw 8 to rotate via bevel gear 12 and bevel gear 24, converting the rotational motion into the horizontal displacement of the sliding plate 5, which in turn causes the plug plate 6 to extend and insert into the plug slot 2 of the adjacent wall panel 1.

[0045] During the insertion process, the insertion plate 6 presses the wedge block 19 to compress the return spring 20. When the locking port 15 is aligned, the return spring pushes the wedge block into the locking port 15 to form a mechanical self-locking mechanism.

[0046] During disassembly, moving the second rotating plate 27 causes the rotating column 22 to rotate, and the annular groove 23 drives the limiting block 25 to pull the movable plate 17, so that the wedge block 19 disengages from the locking port 15. By reversing the operation and moving the first rotating plate 10, the plug plate 6 can be retracted.

[0047] This design ensures a secure connection, easy operation, and supports modular reconfiguration.

[0048] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although detailed descriptions have been provided with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
