Description

Technical Field

[0001] This application relates to the field of display installation technology, and in particular to a display device wall-mounting assembly and a display device body. Background Technology

[0002] With the development of display technology, consumers have increasingly higher requirements for the appearance of display devices, making ultra-thin bodies and borderless designs the mainstream trend in the market. Furthermore, to integrate display devices into the home environment, wall mounting has become one of the mainstream installation methods.

[0003] Hanging a display device on a wall requires a wall mount. However, traditional wall mounts are complex and bulky, resulting in an excessive gap between the display device and the wall after installation. This not only ruins the ultra-thin visual aesthetic of the display device, but also makes it easy for dust to accumulate in the large gap area, making cleaning difficult. Furthermore, the excessive distance between the display device's center of gravity and the wall may pose a safety hazard. Summary of the Invention

[0004] The main purpose of this application is to propose a wall-mounting component for a display device, which aims to solve the technical problems of current wall-mounting methods for display devices, such as excessive distance from the wall, which destroys the ultra-thin visual aesthetics of the display device, easily accumulates dust, and poses safety hazards.

[0005] To achieve the above objectives, this application proposes a wall-mounted display device assembly, comprising:

The second auxiliary fastener is used to fix it to the target wall surface; the second auxiliary fastener is connected to the first auxiliary fastener.

[0007] In one embodiment, the slot has a first slot segment and a second slot segment arranged sequentially; the first slot segment extends in a direction perpendicular to the back surface, and the second slot segment extends in a vertical direction. The cantilever structure has a support portion and a stop portion; the support portion extends in a direction perpendicular to the back side, and one end of the support portion is connected to the wall fixing portion; the stop portion extends in a vertical direction, and one end of the stop portion is connected to the other end of the support portion; the support portion is engaged in the first groove segment, and the stop portion is engaged in the second groove segment.

[0008] In one embodiment, the wall fixing part is configured as a first fitting structure, which is used to be fitted into a first mounting cavity on the target wall surface.

[0009] In one embodiment, the second auxiliary fastener is configured as a second fitting structure, which is used to be fitted into a second mounting cavity in the target wall.

[0010] In one embodiment, the first auxiliary fixing member is configured as a first magnet, and the second auxiliary fixing member is configured as a second magnet; the first magnet and the second magnet are magnetically attracted to each other.

[0011] In one embodiment, at least one of the first magnet and the second magnet is configured as an electromagnet.

[0012] In one embodiment, the first auxiliary fastener is located above the wall mount.

[0013] In one embodiment, the wall mount is located above the first auxiliary fixing member.

[0014] In one embodiment, the back side is provided with at least two slots, which are arranged at intervals in a horizontal direction; the display device wall-mounting assembly includes at least two wall-mounting members, and the cantilever structures of the at least two wall-mounting members are correspondingly engaged in the at least two slots.

[0015] In one embodiment, at least two first auxiliary fasteners are embedded on the back side, and the at least two first auxiliary fasteners are arranged at intervals along the horizontal direction; the display device wall-mounting assembly includes at least two second auxiliary fasteners, and the at least two second auxiliary fasteners are connected to the at least two first auxiliary fasteners in a one-to-one correspondence.

[0016] This application also proposes a display device body for use with a display device wall-mounting assembly as described above; the back of the display device body is provided with a slot, the slot extending into the interior of the display device body along a preset path, the preset path having at least a first component and a second component, the first component being perpendicular to the back of the display device body and the second component being parallel to the back of the display device body. The slot is used to engage with the cantilever structure of the wall-mounted component of the display device; the back side is used to embed the first auxiliary fixing member of the wall-mounted component of the display device.

[0017] In one embodiment, the cantilever structure has a support portion and a stop portion; the support portion extends in a direction perpendicular to the rear side, and one end of the support portion is connected to the wall fixing portion of the display device wall-mounting assembly; the stop portion extends in a vertical direction, and one end of the stop portion is connected to the other end of the support portion. The slot has a first slot segment and a second slot segment arranged in sequence; the first slot segment extends in a direction perpendicular to the back surface, and the second slot segment extends in a vertical direction; the first slot segment is used to engage with the support portion, and the second slot segment is used to engage with the stop portion.

[0018] In one embodiment, the back side is provided with a first receiving cavity, and the slot is disposed on the cavity wall of the first receiving cavity; the wall fixing part of the display device wall-mounting assembly is accommodated in the first receiving cavity.

[0020] The wall-mounted display device assembly proposed in this application has a slot on the back of the display device body with mutually perpendicular first and second components, and an integrated wall mount fixed to the target wall. The cantilever structure of the wall mount has the same extension path as the slot, allowing the cantilever structure to engage with the slot, thus enabling the display device body to be conveniently hung on the wall mount. While the cantilever structure provides the main load-bearing function for the display device body, it also effectively constrains the movement of the display device body in directions perpendicular to and parallel to the back, preventing the display device body from sliding or accidentally detaching. Furthermore, by embedding a first auxiliary fixing member on the back of the display device body and spaced vertically from the wall mount, and fixing a second auxiliary fixing member to the target wall and connecting it to the first auxiliary fixing member, additional auxiliary fixing points can be established between the display device body and the target wall to provide anti-shaking and anti-tipping functions.

[0021] Based on the aforementioned wall-mounted display device assembly, while ensuring the suspension stability and safety of the display device body, the cantilever structure and the first auxiliary fixing component can be housed inside the display device body. This significantly reduces the distance between the display device body and the target wall, making the center of gravity of the display device body closer to the target wall, reducing safety hazards caused by the center of gravity being too far from the wall, and helping to maintain the ultra-thin visual aesthetics of the display device body. Furthermore, by reducing the distance from the wall, dust accumulation is reduced, keeping the area between the display device body and the target wall clean. Attached Figure Description

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0029] With the development of display technology, consumers have increasingly higher requirements for the appearance of display devices, making ultra-thin bodies and borderless designs the mainstream trend in the market. Furthermore, to integrate display devices into the home environment, wall mounting has become one of the mainstream installation methods.

[0030] Hanging a display device on a wall requires a wall mount. However, traditional wall mounts are complex and bulky, resulting in an excessive gap between the display device and the wall after installation. This not only ruins the ultra-thin visual aesthetic of the display device, but also makes it easy for dust to accumulate in the large gap area, making cleaning difficult. Furthermore, the excessive distance between the display device's center of gravity and the wall may pose a safety hazard.

[0031] Based on the above problems, the researchers of this application, through research and analysis of the existing wall mount bracket 2000, discovered that, as Figure 1 As shown, the existing wall mount 2000 typically includes a wall-mounted base 2100 and an equipment mounting plate 2200 made of cold-rolled steel plate. The wall-mounted base 2100 is fixed to the wall surface 1000, and the equipment mounting plate 2200 is connected in a stacked manner to the side of the wall-mounted base 2100 facing away from the wall surface 1000. The display device 3000 is then mounted on the side of the equipment mounting plate 2200 facing away from the wall-mounted base 2100. After the above wall mounting operation is completed, the distance between the display device 3000 and the wall (i.e., the minimum straight-line distance between the back plate of the display device 3000 and the wall surface 1000) is the sum of the thicknesses of the wall-mounted base 2100 and the equipment mounting plate 2200; typically, the distance between the display device 3000 and the wall is 20~50mm.

[0032] To address the issue of excessive distance between the display device and the wall, this application proposes a wall-mounted component for the display device. The traditional wall mount 2000's wall base 2100 and device mounting plate 2200 are integrated into a single wall-mounted structure. The display device can be easily mounted on the wall using this integrated structure, which provides load-bearing support. Furthermore, by adding an auxiliary fixing module, another set of fixing points is established between the display device and the wall to prevent shaking and tipping. This approach minimizes the distance between the display device and the wall while ensuring the stability and safety of the display device's suspension.

[0033] Please see Figure 2 An embodiment of this application provides a wall-mounted display device assembly, comprising: The wall mount 3 has a wall fixing part 31 and a cantilever structure 32; the wall fixing part 31 is used to fix it to the target wall surface 6; the cantilever structure 32 extends along a preset path, and one end of the cantilever structure 32 is connected to the wall fixing part 31; the cantilever structure 32 is used to snap into the slot 2 on the back 11 of the display device body 1. The first auxiliary fixing member 4 is used to be embedded in the back 11; the first auxiliary fixing member 4 and the wall-mounted member 3 are spaced apart in the vertical direction. The second auxiliary fastener 5 is used to fix it to the target wall 6; the second auxiliary fastener 5 is connected to the first auxiliary fastener 4.

[0034] In this embodiment, the target wall surface 6 is typically a vertically installed wall surface inside a building; in some special application scenarios, the target wall surface 6 can also refer to other installation surfaces with a certain angle of inclination. To facilitate the explanation of the technical solution, this embodiment uses the most common vertical wall surface as an example.

[0035] The display device body 1 may include devices with display functions such as LCD TVs, plasma TVs, OLED TVs, monitors, and electronic whiteboards. The display device body 1 has a display screen portion facing the viewer and a back panel portion facing away from the viewer. The side of the back panel portion facing the target wall 6 constitutes the back surface 11 of the display device body 1, and the back surface 11 may be parallel to the target wall 6.

[0036] The back 11 of the display device body 1 is provided with a slot 2, which is a groove-shaped structure recessed inward on the back plate. Specifically, the slot 2 extends into the interior of the display device body 1 along a preset path; the preset path is a virtual path used to describe the direction followed by the slot 2 as it extends into the interior of the display device body 1 from its opening on the back 11.

[0037] The preset path consists of at least two mutually perpendicular components, namely the first component and the second component. The first component is a direction perpendicular to the back surface 11, and the second component is a direction parallel to the back surface 11; wherein, the direction parallel to the back surface 11 can refer to the vertical direction or the horizontal direction, or it can refer to any direction parallel to the back surface 11 that forms a certain angle with the vertical direction.

[0038] The specific geometric shape formed by the extension of the card slot 2 along the preset path can be flexibly set according to the actual situation. For example, the card slot 2 can be set to extend first along a direction perpendicular to the back surface 11, and then extend vertically upward to form an L-shaped structure; the card slot 2 can also be set to extend first along a direction perpendicular to the back surface 11, then transition along an arc direction and continue to extend parallel to the back surface 11 to form a J-shaped structure; the card slot 2 can also be set to extend upward at an angle along a straight line, and this straight line direction can be decomposed into a first component perpendicular to the back surface 11 and a second component parallel to the back surface 11. In practical applications, regardless of whether the specific geometric shape of the card slot 2 is L-shaped, J-shaped or other shapes, as long as the extension path of the card slot 2 can be decomposed into two mutually perpendicular components (i.e., the first component and the second component), it falls within the protection scope of this application.

[0039] The wall mounting part 31 is the portion of the wall mount 3 that directly connects to the target wall surface 6. The wall mounting part 31 can be configured as a strip, plate, block, or other suitable shape. The wall mounting part 31 is usually provided with mounting holes for securely fastening the wall mounting part 31 to the target wall surface 6 using expansion screws, bolts, or other fasteners.

[0040] The cantilever structure 32 is the part of the wall mount 3 that mates with the slot 2. One end of the cantilever structure 32 can be integrally formed with the wall fixing part 31, and the other end of the cantilever structure 32 extends outward along the same preset path as the slot 2. The specific geometry of the cantilever structure 32 can also be flexibly set according to actual needs; for example, the cantilever structure 32 can be set as an L-shaped structure adapted to the L-shaped slot 2, that is, the cantilever structure 32 has a cantilever section perpendicular to the back 11 and a cantilever section parallel to the back 11; the cantilever structure 32 can also be set as a J-shaped structure adapted to the J-shaped slot 2, that is, the cantilever structure 32 has a cantilever section perpendicular to the back 11, a transition section extending along the arc direction, and a cantilever section parallel to the back 11. In practical applications, the shape of the cantilever structure 32 only needs to match the shape of the slot 2 to ensure that the cantilever structure 32 can be snapped into the slot 2.

[0041] In the actual wall-mounted installation process, after the wall fixing part 31 is fixed to the target wall surface 6, the cantilever structure 32 extends outward from the target wall surface 6; then the cantilever structure 32 can be snapped into the slot 2, thereby realizing the snap-fit ​​engagement between the wall mount 3 and the display device body 1. The specific snap-fit ​​method is as follows: First, the display device body 1 can be lifted so that the opening of the slot 2 on the back 11 is aligned with the end of the cantilever structure 32; then the display device body 1 is pushed forward in a direction close to the target wall surface 6, so that the cantilever structure 32 is inserted into the slot 2 in the direction of the first component; then the display device body 1 is moved in a direction parallel to the back 11, so that the cantilever structure 32 slides into the second component path of the slot 2; at this point, the cantilever structure 32 is completely snapped into the slot 2, which realizes the suspension support of the display device body 1 by the wall mount 3.

[0042] Based on the above wall-mounting method, the cantilever structure 32 can be accommodated inside the display device body 1, rather than occupying the space between the display device body 1 and the target wall 6. This reduces the gap between the display device body 1 and the target wall 6, allowing the display device body 1 to be closer to the target wall 6.

[0043] Secondly, both the extension paths of the cantilever structure 32 and the slot 2 have mutually perpendicular first and second components, thus constraining the movement of the display device body 1 in two mutually perpendicular directions. Specifically, when the cantilever structure 32 is inserted into the slot 2, the portion of the cantilever structure 32 extending along the first component restricts the movement of the display device body 1 in a direction parallel to the back surface 11; while the portion of the cantilever structure 32 extending along the second component restricts the movement of the display device body 1 in a direction perpendicular to the back surface 11, thereby preventing the display device body 1 from directly detaching from the target wall 6 in a direction perpendicular to the back surface 11 under external force. Therefore, this multi-directional constraint improves the positional stability of the display device body 1 relative to the target wall 6 after installation.

[0044] Furthermore, the wall-mounting assembly of the display device also includes a first auxiliary fixing member 4 and a second auxiliary fixing member 5. The first auxiliary fixing member 4 is embedded in the back surface 11 of the display device body 1, and can be positioned above or below the wall-mounting component 3. Specifically, the first auxiliary fixing member 4 is at least partially housed inside the display device body 1, and its exposed surface is substantially flush with or slightly lower than the back surface 11. This avoids the first auxiliary fixing member 4 adding extra thickness to the display device body 1, thus maintaining the overall ultra-thin appearance of the display device body 1. A groove structure can be provided on the back surface 11 to fix the first auxiliary fixing member 4 within the groove structure, thereby achieving the embedded fit of the first auxiliary fixing member 4 on the back surface 11. The second auxiliary fixing member 5 can be fixed to the target wall surface 6 using expansion screws, bolts, or other fasteners, or can be fixed to the target wall surface 6 by embedding, bonding, or other methods. The first auxiliary fixing component 4 and the second auxiliary fixing component 5 can be connected by a detachable connection method, such as magnetic connection, snap-on connection, plug-in connection, suction cup connection and other forms. Its function is to establish an additional fixing relationship between the display device body 1 and the target wall 6, in addition to the wall mount 3.

[0045] After the display device body 1 is suspended on the target wall 6 by the wall mount 3, the first auxiliary fixing member 4 and the second auxiliary fixing member 5 are close to each other and connected to each other, so that two fixing points can be formed at different heights on the back 11. The wall mount 3 is mainly used to bear the weight of the display device body 1, while the connection between the first auxiliary fixing member 4 and the second auxiliary fixing member 5 is used to provide auxiliary fixing force. Thus, the shaking of the display device body 1 that may occur during subsequent use can be effectively suppressed through multi-point fixing, and the display device body 1 can be prevented from tipping over when it is hit by an accident.

[0046] Based on the above settings, such as Figure 2As shown, the distance between the display device body 1 and the wall is approximately equal to the thickness of the wall fixing part 31 or the thickness of the second auxiliary fixing part 5; specifically, the distance between the display device body 1 and the wall can be reduced to less than or equal to 10mm.

[0047] Therefore, the wall-mounted display device assembly provided in this embodiment has a slot 2 with a first and a second component perpendicular to each other on the back 11 of the display device body 1, and an integrated wall mount 3 fixed to the target wall 6. The cantilever structure 32 of the wall mount 3 has the same extension path as the slot 2, so that the cantilever structure 32 can be engaged in the slot 2, thereby allowing the display device body 1 to be conveniently hung on the wall mount 3. While the cantilever structure 32 plays the main role of bearing the load on the display device body 1, the cantilever structure 32 can also effectively constrain the movement of the display device body 1 in the direction perpendicular to and parallel to the back 11, preventing the display device body 1 from sliding or accidentally detaching. Furthermore, by embedding the first auxiliary fixing member 4 on the back 11 of the display device body 1 and spaced apart from the wall mount 3 in the vertical direction, and fixing the second auxiliary fixing member 5 to the target wall 6 and connecting it to the first auxiliary fixing member 4, an additional auxiliary fixing point can be established between the display device body 1 and the target wall 6 to provide anti-shaking and anti-tipping functions.

[0048] Based on the aforementioned wall-mounted display device assembly, while ensuring the suspension stability and safety of the display device body 1, the cantilever structure 32 and the first auxiliary fixing member 4 can be accommodated inside the display device body 1. This significantly reduces the distance between the display device body 1 and the target wall 6, making the center of gravity of the display device body 1 closer to the target wall 6, reducing safety hazards caused by the center of gravity being too far from the wall, and helping to maintain the ultra-thin visual aesthetics of the display device body 1. Furthermore, by reducing the distance from the wall, dust accumulation is reduced, keeping the area between the display device body 1 and the target wall 6 clean.

[0049] In one embodiment, refer to Figure 2 The slot 2 has a first slot segment 21 and a second slot segment 22 arranged in sequence; the first slot segment 21 extends in a direction perpendicular to the back surface 11, and the second slot segment 22 extends in a vertical direction. The cantilever structure 32 has a support portion 321 and a stop portion 322; the support portion 321 extends in a direction perpendicular to the back surface 11, and one end of the support portion 321 is connected to the wall fixing portion 31; the stop portion 322 extends in a vertical direction, and one end of the stop portion 322 is connected to the other end of the support portion 321; the support portion 321 is engaged in the first groove segment 21, and the stop portion 322 is engaged in the second groove segment 22.

[0050] Specifically, such as Figure 2As shown, the first groove segment 21 is formed on the back surface 11 and extends horizontally in a direction perpendicular to the back surface 11. The second groove segment 22 can extend upward in a vertical direction. The lower part of the second groove segment 22 is connected to the end of the first groove segment 21 to form an L-shaped slot 2. Correspondingly, the support part 321 extends horizontally in a direction perpendicular to the back surface 11. One end of the support part 321 is connected to the wall fixing part 31, and the other end of the support part 321 is connected to the stop part 322. The stop part 322 can extend upward in a vertical direction. The support part 321 and the stop part 322 together form an L-shaped cantilever structure 32 that matches the shape of the slot 2.

[0051] In the attached state, the support portion 321 engages with the first groove segment 21, and the stop portion 322 engages with the second groove segment 22. The engagement of the support portion 321 with the first groove segment 21 is mainly used to support the weight of the display device body 1, and at the same time, the support portion 321 can be used to restrict the movement of the display device body 1 in the direction parallel to the back surface 11. The engagement of the stop portion 322 with the second groove segment 22 is mainly used to prevent the display device body 1 from detaching from the cantilever structure 32 in the direction perpendicular to the back surface 11; specifically, if an attempt is made to vertically pull the display device body 1 away from the target wall 6, the inner wall of the second groove segment 22 will abut against the stop portion 322 and be blocked by the stop portion 322, thereby preventing the display device body 1 from detaching from the target wall 6.

[0052] Based on the above-mentioned specific structural settings of the slot 2 and the cantilever structure 32, the load-bearing function and the anti-detachment function can be undertaken by different components, thus ensuring the stability of the suspension and optimizing the stress state of each component.

[0053] Understandably, in practical applications, the height of the first slot segment 21 can be set to be greater than or equal to the total height of the cantilever structure 32, so that the stop portion 322 extending in the vertical direction can pass through the first slot segment 21 in a direction perpendicular to the back side 11 during the hanging process, avoiding interference; when the stop portion 322 moves to the end of the first slot segment 21 and is opposite to the second slot segment 22, the display device body 1 can be released, so that the upper inner wall of the first slot segment 21 is pressed against the support portion 321 by gravity, and at the same time, the stop portion 322 is inserted into the second slot segment 22, thereby completing the hanging operation of the display device body 1 on the cantilever structure 32.

[0054] In one embodiment, refer to Figure 3 The wall fixing part 31 is configured as a first fitting structure 31a, which is used to be fitted into the first mounting cavity 61 of the target wall surface 6.

[0055] In this embodiment, the first fitting structure 31a can refer to any structural form suitable for fitting into the cavity, such as a plate-like structure, strip-like structure, or other structural forms that can be fitted into the cavity, and is not limited here. The first mounting cavity 61 is a recessed area pre-cut on the target wall surface 6, and the shape and size of the first mounting cavity 61 are adapted to the first fitting structure 31a. During the installation process, the first fitting structure 31a can be embedded into the first mounting cavity 61, and then the first fitting structure 31a can be fixed in the first mounting cavity 61 by setting fasteners, filling materials, etc.

[0056] like Figure 3 As shown, in this embodiment, the wall fixing part 31 is configured as a first fitting structure 31a that can be fitted into the first mounting cavity 61, so that the wall fixing part 31 no longer protrudes from the target wall surface 6, but can be accommodated inside the target wall surface 6. This configuration allows the back side 11 of the display device body 1 to be closer to the target wall surface 6, which further reduces the distance between the display device body 1 and the target wall surface 6, which is beneficial to improving the hanging stability and safety of the display device body 1, and can also improve the integrated visual effect of the display device body 1 and the target wall surface 6. At the same time, by embedding the wall fixing part 31 into the wall, the connection between the wall mount 3 and the wall is more stable, which is beneficial to improving the load-bearing capacity and tensile strength of the wall mount 3.

[0057] In one embodiment, refer to Figure 3 The second auxiliary fastener 5 is configured as a second fitting structure 5a, which is used to be fitted into the second mounting cavity 62 of the target wall 6.

[0058] In this embodiment, the second fitting structure 5a can refer to any structural form suitable for fitting into the cavity, such as a block structure, strip structure, or other structural forms that can fit into the cavity, and is not limited here. The second mounting cavity 62 is a recessed area pre-cut on the target wall surface 6, and the shape and size of the second mounting cavity 62 are adapted to the second fitting structure 5a. During installation, the second fitting structure 5a can be embedded into the second mounting cavity 62, and then the second fitting structure 5a can be fixed in the second mounting cavity 62 by setting fasteners, filling materials, etc.

[0059] like Figure 3As shown, in this embodiment, the second auxiliary fixing member 5 is configured as a second fitting structure 5a that can be fitted into the second mounting cavity 62, so that the second auxiliary fixing member 5 no longer protrudes from the target wall 6, but can be accommodated inside the target wall 6. This configuration allows the back surface 11 of the display device body 1 to be closer to the target wall 6, thereby further reducing the distance between the display device body 1 and the target wall 6, which is beneficial to improving the suspension stability and safety of the display device body 1, and can also improve the integrated visual effect of the display device body 1 and the target wall 6. At the same time, by embedding the second auxiliary fixing member 5 into the wall, the connection between the second auxiliary fixing member 5 and the wall can be made more stable.

[0060] Preferably, when the wall fixing part 31 is configured as the first fitting structure 31a and embedded in the first mounting cavity 61 of the target wall surface 6, and the second auxiliary fixing member 5 is simultaneously configured as the second fitting structure 5a and embedded in the second mounting cavity 62 of the target wall surface 6, such as Figure 3 As shown, at this time, the wall fixing part 31 and the second auxiliary fixing part 5 are both accommodated inside the target wall 6, so that the back side 11 of the display device body 1 can be flush with the target wall 6, thereby achieving theoretical zero distance from the wall, which can maximize the suspension stability and safety of the display device body 1, and maximize the improvement of the ultra-thin visual aesthetics of the display device body 1.

[0061] In one embodiment, refer to Figure 2 The first auxiliary fixing component 4 is configured as a first magnet, and the second auxiliary fixing component 5 is configured as a second magnet; the first magnet and the second magnet are magnetically attracted to each other.

[0062] In this embodiment, the first magnet is embedded in the back 11 of the display device body 1, and the second magnet is fixed to the target wall 6. When the display device body 1 is suspended from the target wall 6 by the wall mount 3, the first magnet and the second magnet approach each other and generate a magnetic attraction force, thereby making the first magnet and the second magnet tightly attracted to each other, so as to play an auxiliary fixing role in the display device body 1 and prevent the display device body 1 from shaking or tipping over.

[0063] The specific composition of the first and second magnets can be flexibly selected according to actual needs. For example, the first magnet can be a magnet block made of permanent magnet material, and the second magnet can be an iron or steel part that can be attracted by the magnet. In this case, the first magnet provides a magnetic field, and the second magnet generates an attraction force after being magnetized. Alternatively, both the first and second magnets can be permanent magnets with opposite polarities, so that they can generate an attraction force through the attraction of opposite poles.

[0064] Based on the above configuration, when the display device body 1 moves to the preset mounting position, the first magnet and the second magnet can automatically align and engage, completing the auxiliary fixation without additional operation. This effectively suppresses the shaking of the display device body 1 caused by external force disturbance during use and prevents the display device body 1 from tipping over in the event of an accidental collision. Simultaneously, this magnetic engagement method simplifies the structure of the auxiliary fixing component and makes subsequent disassembly and maintenance easier.

[0065] In one embodiment, refer to Figure 2 At least one of the first magnet and the second magnet is configured as an electromagnet.

[0066] Specifically, an electromagnet is a magnetic element that generates a magnetic field when an electric current is passed through it. The generation and disappearance of its magnetic field can be controlled by a circuit. When an electromagnet is energized, it generates magnetism and can attract corresponding magnets or iron parts; when the electromagnet is de-energized, its magnetism disappears, and the magnetic attraction force will be released.

[0067] By setting at least one magnet as an electromagnet, active control of the auxiliary fixing effect can be achieved. For example, during installation, the electromagnet can be de-energized to avoid interference from the magnetic attraction force. After the display device body 1 is moved to the preset hanging position, the electromagnet is energized to generate a magnetic attraction force to achieve auxiliary fixing. When it is necessary to disassemble the display device body 1 later, the electromagnet can be de-energized to make the magnetic attraction force disappear, which makes it easier to remove the display device body 1.

[0068] Based on the aforementioned controllable magnetic fixing method, the ease of installation and removal of the display device body 1 can be further improved.

[0069] In one embodiment, refer to Figure 2 The first auxiliary fixing part 4 is located above the wall-mounted part 3.

[0070] In one embodiment, refer to Figure 5 The wall mount 3 is located above the first auxiliary fixing part 4.

[0071] Specifically, the first auxiliary fixing member 4 can be disposed above the wall-mounted member 3, and correspondingly, the second auxiliary fixing member 5 is also disposed above the wall-mounted member 3, to form a configuration as follows: Figure 2 The structure shown is a bottom hanging and an upper auxiliary fixing structure. During the installation process, the lower wall mount 3 and the slot 2 can be connected first, and the upper first auxiliary fixing part 4 can be fixed to the second auxiliary fixing part 5 by magnetic attraction or other means, thereby completing the hanging of the display device body 1 on the target wall 6.

[0072] Similarly, the wall mount 3 can be positioned above the first auxiliary fixing member 4, and correspondingly, the wall mount 3 is also positioned above the second auxiliary fixing member 5, to form a configuration as shown below. Figure 5 The structure shown is a top-mounted and bottom-assisted fixing structure. During installation, the upper wall mount 3 and the slot 2 can be engaged first, and the lower first auxiliary fixing part 4 can then be fixed to the second auxiliary fixing part 5 by magnetic attraction or other means, thereby completing the mounting of the display device body 1 on the target wall 6.

[0073] In practical applications, the above two structural forms can be flexibly selected according to the structural layout, center of gravity position and installation requirements of the display device body 1, and this application does not limit them.

[0074] In one embodiment, refer to Figure 6 The back 11 is provided with at least two slots 2, which are arranged at intervals in the horizontal direction; the display device wall-mounting assembly includes at least two wall-mounting parts 3, and the cantilever structures 32 of the at least two wall-mounting parts 3 are correspondingly engaged in the at least two slots 2.

[0075] In one embodiment, refer to Figure 6 The back 11 is provided with at least two first auxiliary fasteners 4, which are arranged at intervals in the horizontal direction; the wall-mounted component of the display device includes at least two second auxiliary fasteners 5, which are connected one-to-one with the at least two first auxiliary fasteners 4.

[0076] like Figure 6 As shown, taking two slots 2 and two wall mounts 3 as an example, the two slots 2 and two wall mounts 3 can be arranged at intervals along the width direction of the display device body 1, and the cantilever structures 32 of the two wall mounts 3 are correspondingly engaged in the two slots 2. When the number of slots 2 and wall mounts 3 is more than two, the specific layout can be set in the same way as described above, and will not be elaborated here.

[0077] By setting at least two sets of slots 2 and wall mounts 3 that are spaced apart in the horizontal direction, the number of suspension support points in the horizontal direction can be increased, making the force on the display device body 1 more uniform, which is conducive to improving the stability and load-bearing capacity of the hanging operation.

[0078] In addition, such as Figure 6As shown, taking an example where both the first auxiliary fixing member 4 and the second auxiliary fixing member 5 are set to two, the two first auxiliary fixing members 4 and the two second auxiliary fixing members 5 can be arranged at intervals along the width direction of the display device body 1, with the two first auxiliary fixing members 4 and the two second auxiliary fixing members 5 connected in a one-to-one correspondence. When the number of first auxiliary fixing members 4 and second auxiliary fixing members 5 is more than two, the specific layout can be set in the same way as described above, and will not be elaborated here.

[0079] By setting at least two sets of auxiliary fixing parts spaced apart in the horizontal direction, auxiliary fixing points can be added in the horizontal direction, thereby further suppressing the shaking that may occur in the display device body 1 during use and enhancing the anti-shake and anti-tipping effects.

[0080] Preferably, such as Figure 6 As shown, the number of first auxiliary fixing parts 4 is the same as the number of slots 2, and the first auxiliary fixing parts 4 are respectively set above or below the slots 2; correspondingly, the number of second auxiliary fixing parts 5 is the same as the number of wall-mounted parts 3, and the second auxiliary fixing parts 5 are respectively set above or below the wall-mounted parts 3; thus, a multi-point fixing system can be formed, which can further improve the overall fixing effect of the display device body 1 on the target wall 6.

[0081] In one embodiment, refer to Figure 7 The wall mount 3 has a cleaning channel 33; one end of the cleaning channel 33 is connected to the outside, and the other end of the cleaning channel 33 is connected to the gap area between the display device body 1 and the target wall 6.

[0082] Specifically, the cleaning channel 33 can be installed through the wall mount 3. When it is necessary to clean the back of the display device body 1 and the gap area between the display device body 1 and the target wall 6, an air supply device can be connected to the outward end of the cleaning channel 33. In this way, the airflow output by the air supply device can be blown to the area to be cleaned through the cleaning channel 33, so that the airflow can be used to remove dust from the area to be cleaned without having to extend the cleaning tools into the narrow space between the display device body 1 and the target wall 6, thereby improving the convenience of cleaning.

[0083] In one embodiment, the wall mount 3 is made of a thermally conductive metal material; the contact area between the wall mount 3 and the display device body 1 is directly opposite the circuit board assembly inside the display device body 1.

[0084] Specifically, the circuit board assembly inside the display device body 1 may include functional components such as the motherboard and power module that generate significant heat during operation. In this embodiment, by placing the wall mount 3 directly opposite the aforementioned core heat-generating area of ​​the display device body 1, the high thermal conductivity of the wall mount 3 can effectively dissipate the heat generated in the core heat-generating area during the operation of the display device body 1, thereby reducing the operating temperature of the display device body 1 and improving its operational stability.

[0085] This application embodiment also provides a display device body 1, please refer to... Figure 2 The display device body 1 is used in conjunction with the display device wall-mounting assembly in any of the above embodiments; the back side 11 of the display device body 1 is provided with a slot 2, the slot 2 extends into the interior of the display device body 1 along a preset path, the preset path has at least a first component and a second component, the first component is perpendicular to the back side 11, and the second component is parallel to the back side 11. The slot 2 is used to engage with the cantilever structure 32 of the wall-mounted display device assembly; the back 11 is used to embed the first auxiliary fixing member 4 of the wall-mounted display device assembly.

[0086] In this embodiment, the display device body 1 may include devices with display functions such as LCD TVs, plasma TVs, OLED TVs, monitors, and electronic whiteboards. The display device body 1 has a display screen portion facing the viewer and a back panel portion facing away from the viewer. The side of the back panel portion facing the target wall 6 constitutes the back surface 11 of the display device body 1, and the back surface 11 may be parallel to the target wall 6.

[0087] For the specific structure of the display device wall-mounting assembly, please refer to the description of the above embodiments. Since the display device body 1 in this embodiment corresponds to the technical solution of the above embodiments, it possesses at least all the beneficial effects brought about by the technical solution of the above embodiments. That is, a slot 2 with mutually perpendicular first and second components is provided on the back 11 of the display device body 1, and an integrated wall-mounting component 3 fixed to the target wall 6 is provided. The cantilever structure 32 of the wall-mounting component 3 has the same extension path as the slot 2, allowing the cantilever structure 32 to engage with the slot 2, thereby conveniently hanging the display device body 1 on the wall-mounting component 3. The cantilever structure 32 is used to support the display device body 1... While fulfilling its primary load-bearing function, the cantilever structure 32 can also effectively constrain the movement of the display device body 1 in directions perpendicular to and parallel to the back 11, preventing the display device body 1 from sliding or accidentally detaching. Furthermore, by embedding the first auxiliary fixing member 4 into the back 11 of the display device body 1 and spacing it vertically from the slot 2 and the wall mount 3, and fixing the second auxiliary fixing member 5 to the target wall 6 and connecting it to the first auxiliary fixing member 4, an additional auxiliary fixing point can be established between the display device body 1 and the target wall 6 to provide anti-shaking and anti-tipping functions. Based on the above solution, while ensuring the suspension stability and safety of the display device body 1, the cantilever structure 32 and the first auxiliary fixing member 4 can be accommodated inside the display device body 1. This significantly reduces the distance between the display device body 1 and the target wall 6, making the center of gravity of the display device body 1 closer to the target wall 6, reducing the safety hazards caused by the center of gravity being too far from the wall, and helping to maintain the ultra-thin visual aesthetics of the display device body 1. Furthermore, by reducing the distance from the wall, dust accumulation is reduced, and the cleanliness of the area between the display device body 1 and the target wall 6 can be maintained.

[0088] In one embodiment, refer to Figure 2 The cantilever structure 32 has a support portion 321 and a stop portion 322; the support portion 321 extends in a direction perpendicular to the back surface 11, and one end of the support portion 321 is connected to the wall fixing portion 31 of the display device wall mounting assembly; the stop portion 322 extends in a vertical direction, and one end of the stop portion 322 is connected to the other end of the support portion 321. The slot 2 has a first slot segment 21 and a second slot segment 22 arranged in sequence; the first slot segment 21 extends in a direction perpendicular to the back surface 11, and the second slot segment 22 extends in a vertical direction; the first slot segment 21 is used to engage with the support portion 321, and the second slot segment 22 is used to engage with the stop portion 322.

[0089] Specifically, such as Figure 2As shown, the first groove segment 21 is formed on the back surface 11 and extends horizontally in a direction perpendicular to the back surface 11. The second groove segment 22 can extend upward in a vertical direction. The lower part of the second groove segment 22 is connected to the end of the first groove segment 21 to form an L-shaped slot 2. Correspondingly, the support part 321 extends horizontally in a direction perpendicular to the back surface 11. One end of the support part 321 is connected to the wall fixing part 31, and the other end of the support part 321 is connected to the stop part 322. The stop part 322 can extend upward in a vertical direction. The support part 321 and the stop part 322 together form an L-shaped cantilever structure 32 that matches the shape of the slot 2.

[0090] In the attached state, the support portion 321 engages with the first groove segment 21, and the stop portion 322 engages with the second groove segment 22. The engagement of the support portion 321 with the first groove segment 21 is mainly used to support the weight of the display device body 1, and at the same time, the support portion 321 can be used to restrict the movement of the display device body 1 in the direction parallel to the back surface 11. The engagement of the stop portion 322 with the second groove segment 22 is mainly used to prevent the display device body 1 from detaching from the cantilever structure 32 in the direction perpendicular to the back surface 11; specifically, if an attempt is made to vertically pull the display device body 1 away from the target wall 6, the inner wall of the second groove segment 22 will abut against the stop portion 322 and be blocked by the stop portion 322, thereby preventing the display device body 1 from detaching from the target wall 6.

[0091] Based on the above-mentioned specific structural settings of the slot 2 and the cantilever structure 32, the load-bearing function and the anti-detachment function can be undertaken by different components, thus ensuring the stability of the suspension and optimizing the stress state of each component.

[0092] Understandably, in practical applications, the height of the first slot segment 21 can be set to be greater than or equal to the total height of the cantilever structure 32, so that the stop portion 322 extending in the vertical direction can pass through the first slot segment 21 in a direction perpendicular to the back side 11 during the hanging process, avoiding interference; when the stop portion 322 moves to the end of the first slot segment 21 and is opposite to the second slot segment 22, the display device body 1 can be released, so that the upper inner wall of the first slot segment 21 is pressed against the support portion 321 by gravity, and at the same time, the stop portion 322 is inserted into the second slot segment 22, thereby completing the hanging operation of the display device body 1 on the cantilever structure 32.

[0093] In one embodiment, refer to Figure 4 The back 11 is provided with a first receiving cavity 111, and the slot 2 is provided on the cavity wall of the first receiving cavity 111; the wall fixing part 31 of the display device wall mounting assembly is accommodated in the first receiving cavity 111.

[0094] In this embodiment, the first accommodating cavity 111 is a cavity structure formed by the inward recess of the back surface 11 of the display device body 1, and the opening of the first accommodating cavity 111 faces the target wall surface 6. The slot 2 is formed in the cavity wall of the first accommodating cavity 111, that is, the slot 2 is located within the coverage area of ​​the first accommodating cavity 111. When the display device body 1 is hung on the wall mount 3, the cantilever structure 32 is engaged in the slot 2, and the wall fixing part 31 is accommodated in the first accommodating cavity 111.

[0095] like Figure 4 As shown, the first accommodating cavity 111 provides a accommodating space for the wall fixing part 31, so that the wall mount 3 can be accommodated inside the display device body 1 without occupying additional space between the display device body 1 and the target wall 6. This can further reduce the distance between the display device body 1 and the target wall 6, so that the display device body 1 can be closer to the target wall 6.

[0096] Based on the above configuration, the gap between the display device body 1 and the target wall 6 is further reduced, which helps to improve the suspension stability and safety of the display device body 1 and improves the integrated visual effect of the display device body 1 and the target wall 6. At the same time, since the wall mount 3 is entirely housed in the first receiving cavity 111, the wall mount 3 is prevented from being exposed to the external space, thereby reducing the possibility of dust accumulation and making daily cleaning and maintenance easier. In addition, the first receiving cavity 111 can also provide a certain degree of protection for the wall mount 3, reducing the risk of accidental collisions to the wall mount 3 and improving the safety of the display device wall mount assembly.

[0097] In one embodiment, refer to Figure 4 The back 11 is provided with a second receiving cavity 112, and the first auxiliary fixing member 4 is embedded in the cavity wall of the second receiving cavity 112; the second auxiliary fixing member 5 of the display device wall-mounting assembly is accommodated in the second receiving cavity 112.

[0098] In this embodiment, the second accommodating cavity 112 is a cavity structure formed by the inward recess of the back surface 11 of the display device body 1, and the opening of the second accommodating cavity 112 faces the target wall surface 6. When the display device body 1 is hung on the wall mount 3, the second auxiliary fixing member 5 is accommodated in the second accommodating cavity 112.

[0099] like Figure 4 As shown, the second accommodating cavity 112 provides a accommodating space for the second auxiliary fixing member 5, so that the second auxiliary fixing member 5 can be accommodated inside the display device body 1 without occupying additional space between the display device body 1 and the target wall 6. This can further reduce the distance between the display device body 1 and the target wall 6, so that the display device body 1 can be closer to the target wall 6.

[0100] Based on the above configuration, the gap between the display device body 1 and the target wall 6 is further reduced, which helps to improve the suspension stability and safety of the display device body 1 and improves the integrated visual effect of the display device body 1 and the target wall 6. At the same time, since the second auxiliary fixing member 5 is accommodated in the second receiving cavity 112, the second auxiliary fixing member 5 is prevented from being exposed to the external space, thereby reducing the possibility of dust accumulation and making daily cleaning and maintenance easier; in addition, the second receiving cavity 112 can also provide a certain degree of protection for the second auxiliary fixing member 5.

[0101] Preferably, when the wall fixing part 31 is accommodated in the first receiving cavity 111 and the second auxiliary fixing member 5 is accommodated in the second receiving cavity 112, such as Figure 4 As shown, at this time, the wall fixing part 31 and the second auxiliary fixing part 5 are both accommodated inside the display device body 1, so that the back 11 of the display device body 1 can be flush with the target wall 6, thereby achieving a theoretical zero distance from the wall, which can maximize the suspension stability and safety of the display device body 1, and maximize the improvement of the ultra-thin visual aesthetics of the display device body 1.

[0102] The above description is merely an exemplary embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the technical concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
