Description

Technical Field

[0001] This application relates to the field of display device technology, and in particular to a wall-mounted structure and display device. Background Technology

[0002] Existing display devices are typically mounted on walls using a wall-mounting mechanism. A common wall-mounting method involves attaching the display device's mounting bracket to hooks on the wall. However, in actual use, factors such as vibration or accidental impacts can cause the connection between the mounting bracket and the hooks to loosen, or even cause the mounting bracket to accidentally detach from the hooks, posing a safety hazard of the device falling. Utility Model Content

[0003] The purpose of this application is to provide a wall-mounted structure and display device, which aims to solve the problem of poor anti-detachment effect in existing wall-mounted structures.

[0004] To achieve the above objectives, the technical solution adopted in this application is as follows: In a first aspect, embodiments of this application provide a wall-mounted structure, including: The first bracket includes a main body and a flexible hook. The hook includes a mounting part and a limiting part. The limiting part is connected to the front side of the main body via the mounting part. The limiting part extends upward from the mounting part and is disposed opposite to the main body to form a mounting channel between the hook and the main body. The limiting part is provided with a first protrusion located in the mounting channel. A spring sheet is provided on the front side of the main body and is disposed opposite to the limiting part, and the spring sheet is provided with a second protrusion located in the hooking channel; A lifting ring, one side of which is attached to the hanging channel and supported on the mounting part, wherein the first protrusion and the second protrusion are used to prevent the lifting ring from coming out of the hanging channel in the height direction when the lifting ring is attached to the hanging channel; The second bracket is connected to the other side of the lifting ring away from the mounting part.

[0005] In some embodiments, when the lifting ring is attached to the attachment channel, the first protrusion or the second protrusion abuts against one side of the lifting ring.

[0006] In some embodiments, a first constriction exists between the first protrusion and the second protrusion in a cross-section along the height direction.

[0007] In some embodiments, the crests of the first protrusion and the crests of the second protrusion are offset in the height direction.

[0008] In some embodiments, the distance between the crest of the first protrusion and the crest of the second protrusion in the height direction is 3~5mm.

[0009] In some embodiments, the limiting portion is further provided with a third protrusion located in the hooking channel. The third protrusion is distributed along the height direction with the first protrusion. The third protrusion is used to prevent the hook from coming out of the hooking channel along the height direction when the hook is hooked in the hooking channel.

[0010] In some embodiments, in a cross-section along the height direction, the third protrusion has a second constriction between it and the spring sheet.

[0011] In some embodiments, in the height direction, the peak of the third protrusion is higher than the peak of the first protrusion, and the peak of the first protrusion is higher than the peak of the second protrusion.

[0012] In some embodiments, the first protrusion and the third protrusion are arranged continuously.

[0013] In some embodiments, the limiting portion is provided with a set of first protrusions and a set of third protrusions on both sides along the horizontal direction, and the spring piece and the second protrusion are located between the two sets of first protrusions and the third protrusions in the horizontal direction.

[0014] In some embodiments, in at least one of the first protrusion, the second protrusion, and the third protrusion, the protrusion includes a first inclined wall and a second inclined wall, the first inclined wall being connected to the side of the second inclined wall away from the mounting portion, the first inclined wall and the second inclined wall having an included angle, and the first inclination angle of the first inclined wall relative to the height direction being smaller than the second inclination angle of the second inclined wall relative to the height direction.

[0015] In some embodiments, one side of the lifting ring is rotatable relative to the mounting portion, so that the lifting ring can swing toward or away from the main body; the second bracket has a rotating side, which is rotatably connected to the other side of the lifting ring; The bottom side of the main body is provided with a stop for stopping above the rotating side.

[0016] Secondly, this application also provides a display device, including: a display unit and a wall-mounted structure as described in the above embodiments, wherein the main body is used to be installed on a wall, and the display unit is connected to the second bracket.

[0017] The beneficial effects of the wall-mounted structure and display device provided in this application are as follows: Compared with the prior art, this application forms a double-protrusion limiting structure by setting a first protrusion on the hook limiting part and cooperating with a second protrusion set on the spring piece. The two protrusions work together to restrain the hanging ring in the hanging channel, so that the hanging ring is reliably restrained in the hanging channel after installation. When the hanging ring comes off upward, it needs to overcome the double elastic deformation resistance of the hook and the spring piece, thereby effectively improving the anti-loosening performance and improving the safety and reliability of the wall-mounted connection.

For those skilled in the art, the specific meaning of the above terms in the embodiments of this application can be understood according to the specific circumstances.

[0025] Display devices are typically mounted on walls using wall-mounting structures. However, existing wall-mounting structures have poor anti-detachment properties, posing a safety hazard of device falls. Therefore, this application provides a wall-mounting structure that, by incorporating multiple protruding structures arranged in opposite directions within the mounting channel, effectively prevents the hanging rings from accidentally detaching, significantly improving the reliability and safety of the wall-mounting connection.

[0026] In some embodiments, refer to Figures 1 to 8 As shown, this application embodiment provides a wall-mounted structure, including: a first bracket 1, a spring piece 2, a hanging ring 3, and a second bracket 4. The first bracket 1 includes a main body 11 and an elastic hook 12. The hook 12 includes a mounting portion 121 and a limiting portion 122. The limiting portion 122 is connected to the front side of the main body 11 via the mounting portion 121. The limiting portion 122 extends upward from the mounting portion 121 and is disposed opposite to the main body 11 to form a mounting channel 123 between the hook 12 and the main body 11. The limiting portion 122 has a first protrusion 124 located within the mounting channel 123; the spring piece 2... The spring piece 2 is located on the front side of the main body 11 and is opposite to the limiting part 122. The spring piece 2 is provided with a second protrusion 21 located in the hooking channel 123. One side of the lifting ring 3 is hooked in the hooking channel 123 and supported on the mounting part 121. The first protrusion 124 and the second protrusion 21 are used to prevent the lifting ring 3 from coming out of the hooking channel 123 along the height direction Z when the lifting ring 3 is hooked in the hooking channel 123. The second bracket 4 is connected to the other side of the lifting ring 3 away from the mounting part 121.

[0027] like Figure 1 As shown, the height direction Z is the vertical direction in which the lifting ring 3 is inserted into or removed from the hooking channel 123.

[0028] like Figure 2 As shown, the main body 11 of the first bracket 1 can be a sheet metal part, and the sheet metal material can include galvanized sheet, stainless steel sheet, aluminum alloy sheet, etc., which is conducive to realizing the ultra-thin design of the wall-mounted structure. The shape of the main body 11 can be triangular, square, circular, elliptical, etc. As the basic support of the entire wall-mounted structure, the main body 11 can be provided with first fastening holes 111 to facilitate installation and fixation to the wall by bolts or other fasteners. For example, the main body 11 is a square sheet metal part, and the four corners of the main body 11 are respectively provided with first fastening holes 111, and the main body 11 is fixed to the wall by four bolts.

[0029] like Figure 2 As shown, the flexible hook 12 is integrated into the front side of the main body 11, which refers to the side facing away from the wall, i.e., the side facing the display device. The flexible hook 12 can be connected to the main body 11 by welding, integral molding, or other methods. For example, as shown... Figure 2As shown, a cutting line can be made in the middle of the main body 11 to cut out a tongue-shaped portion that connects to the upper side of the main body 11. This tongue-shaped portion then protrudes forward and bends upward, forming an elastic hook 12 with a mounting portion 121 and a limiting portion 122. This design fully utilizes the structure of the main body 11 itself, eliminating the need for a separate hook component, resulting in a simple structure and cost savings. The mounting portion 121 is located at the bottom of the hook 12, and its shape can be adapted to fit the lifting ring 3 to support it. For example, the shape of the mounting portion 121 can be arc-shaped. The limiting portion 122 is located on the front side of the hook 12 and is positioned opposite to the main body 11, i.e., the limiting portion 122 and the main body 11 are positioned opposite each other in the front-rear direction Y. Thus, a mounting channel 123 for attaching the lifting ring 3 can be constructed between the hook 12 and the main body 11. The cross-sectional shape of the hanging channel 123 can be U-shaped or C-shaped, with openings at the top and on the left and right sides. Through the top opening, the lifting ring 3 can be vertically inserted into or removed from the hanging channel 123, making operation simple and convenient. Through the side openings, the lifting ring 3 can be easily moved horizontally in the X direction to adjust its installation position. Furthermore, the limiting part 122 has a first protrusion 124 that protrudes into the hanging channel 123, forming a barrier to prevent the lifting ring 3 from detaching. Figure 6 As shown. The first protrusion 124 can be welded or integrally formed onto the limiting portion 122. As an example, as Figure 2 and Figure 6 As shown, the limiting part 122 can be stamped to form a first protrusion 124 on the limiting part 122.

[0030] like Figure 3 As shown, the spring piece 2 refers to an elastic sheet-like component, such as a metal sheet or a plastic sheet. Preferably, the spring piece 2 is a metal sheet, and the metal material can be stainless steel, aluminum alloy, etc. The spring piece 2 itself is elastic and can deform under force, allowing the lifting ring 3 to overcome elastic resistance and complete the action during installation or removal. The spring piece 2 can be installed on the front side of the main body 11 by riveting, bolting, welding, etc. As an example, such as Figures 1 to 3 As shown, the hook 12 has a recess 125 in the middle. The main body 11 has a rib 112 extending downwards to the outside of the hooking channel 123 at the position corresponding to the recess 125. The main body 11 and the rib 112 each have a first riveting hole 113. A portion of the spring piece 2 is located on the main body 11 at the position corresponding to the recess 125 and inside the hooking channel 123, while the other portion is located on the rib 112 outside the hooking channel 123. The two portions of the spring piece 2 each have a second riveting hole 22 corresponding to one of the first riveting holes 113. The second riveting holes 22 and the first riveting holes 113 can be riveted together with rivets. Furthermore, the spring piece 2 has a second protrusion 21 located between the two second riveting holes 22. This protrusion protrudes into the hooking channel 123 in the opposite direction to the first protrusion 124, thus preventing the lifting ring 3 from detaching. Figure 6 As shown. The second protrusion 21 can be welded or integrally formed onto the spring piece 2. For example, as Figure 3 As shown, the spring piece 2 can be stamped to form a second protrusion 21 on the spring piece 2. In addition, a strip hole 23 penetrating the second protrusion 21 can be opened vertically on the spring piece 2, which is beneficial to improving the elastic deformation performance.

[0031] like Figure 1 As shown, the lifting ring 3 serves as an intermediate connector, with one end inserted into the hanging channel 123 and supported on the mounting part 121, and the other end connected to the second bracket 4. The lifting ring 3 can be a closed or open ring structure. As an example, such as Figure 4 As shown, a metal rod can be bent to form a lifting ring 3 with open ends, and both ends can be further bent inwards, extending upwards to form an extension end 31. The extension end 31 can be located at the lower center of the lifting ring 3. The metal rod can be cylindrical in shape. The material of the metal rod can be steel, aluminum, etc.

[0032] like Figure 5 As shown, the second bracket 4 can be a sheet metal part, and the sheet metal material can include galvanized sheet, stainless steel sheet, aluminum alloy sheet, etc., which is beneficial for achieving an ultra-thin design of the wall-mounted structure. The shape of the second bracket 4 can be triangular, square, circular, elliptical, etc. A second fastening hole 41 can be provided on the second bracket 4 to facilitate the installation and fixing of the display device (such as an LCD TV, display screen, etc.) using bolts or other fasteners. For example, as shown... Figure 1 and Figure 5 As shown, a square sheet metal part can be folded along the ring of the lifting ring 3 to cover the lifting ring 3. Then, the two folded parts of the sheet metal part are riveted together to form a second bracket 4 connected to the lifting ring 3, and the second fastening hole 41 passes through the two folded parts of the sheet metal part.

[0033] The wall-mounted structure provided in this application embodiment mainly achieves a reliable anti-detachment function through the synergistic effect of the first protrusion 124 and the second protrusion 21. The working principle of the wall-mounted structure provided in this application embodiment is described below.

[0034] Installation process: The main body 11 of the first bracket 1 is fixed to the wall with bolts, and the second bracket 4 is fixed to the back of the display device with bolts. The display device is then lifted, and the hanging ring 3 is hooked onto the hook 12, completing the installation of the display device. During the process of the user inserting the hanging ring 3 into the hanging channel 123 from top to bottom, due to the weight of the device and the force applied by the user, the hanging ring 3 will contact and press against the first protrusion 124 and the second protrusion 21, causing the hook limiting part 122 and the spring piece 2 to undergo elastic deformation, thus allowing the hanging ring 3 to be smoothly pressed into place and supported on the hanging part 121 of the hook 12. After the hanging ring 3 is installed in place, the hook limiting part 122 and the spring piece 2 return to their original state, and the double protrusion structure is reset.

[0035] Anti-detachment state: When the hanging ring 3 is hooked into the hooking channel 123, it is restrained within the hooking channel 123 by the first protrusion 124 and the second protrusion 21 above. When vibration or accidental collision causes the hanging ring 3 to be subjected to an upward external force and attempt to detach, its upward movement tendency will be blocked by the first protrusion 124 and the second protrusion 21. To detach the hanging ring 3, sufficient external force needs to be applied to overcome the elastic deformation resistance of the hook limiting part 122 (to make the first protrusion 124 give way) and the elastic deformation resistance of the spring piece 2 (to make the second protrusion 21 give way). Since the two protrusions exert a blocking effect from both sides, a single-direction impact is difficult to overcome the elastic constraints on both sides, significantly increasing the difficulty of detachment, thereby preventing the display device from accidentally falling off.

[0036] Release process: When it is necessary to disassemble the display device, the user needs to apply an external force upward to overcome the elastic deformation resistance of the hook limiting part 122 and the elastic deformation resistance of the spring piece 2, so that the first protrusion 124 and the second protrusion 21 give way, and the hanging ring 3 can be released from the top opening of the hanging channel 123 along the height direction Z.

[0037] Therefore, the wall-mounted structure provided in this application embodiment, by setting opposing double protrusions within the hanging channel 123, can create double obstruction for the hanging ring 3, effectively preventing it from accidentally detaching due to vibration or external force during use, thereby improving the safety and reliability of the wall-mounted structure and reducing the risk of the display device falling. Furthermore, no additional locking mechanism is required; the anti-detachment function can be achieved through a simple combination of protrusions and elasticity, resulting in a simple structure and low cost.

[0038] In some embodiments, the first protrusion 124 and the second protrusion 21 may be located at the same height or at different heights.

[0039] In some embodiments, the first protrusion 124 and the second protrusion 21 can be elastic elements that can undergo elastic deformation under the compression of the lifting ring 3.

[0040] In some embodiments, refer to Figures 6 to 8As shown, when the lifting ring 3 is attached to the hanging channel 123, the first protrusion 124 or the second protrusion 21 abuts against one side of the lifting ring 3.

[0041] In the normal engaged state of the lifting ring 3, only one of the first protrusion 124 or the second protrusion 21 contacts and abuts against the surface of the lifting ring 3, while the other protrusion has a gap with the lifting ring 3. As an example, such as... Figure 6 As shown, the second protrusion 21 abuts against the lifting ring 3, and there is a gap between the first protrusion 124 and the lifting ring 3. In other examples, the first protrusion 124 abuts against the lifting ring 3, and there is a gap between the second protrusion 21 and the lifting ring 3.

[0042] Understandably, when the lifting ring 3 is inserted or removed, it only contacts the first protrusion 124 or the second protrusion 21 at the same time, thus avoiding the need to overcome the resistance of both protrusions simultaneously and reducing operational resistance. However, when the display device is subjected to external impact or vibration, causing the lifting ring 3 to attempt to detach upwards, the protrusions at different positions will still provide multiple obstructions.

[0043] Therefore, through the above design, the embodiments of this application can improve assembly convenience and user operation experience while ensuring the anti-detachment function.

[0044] In some embodiments, refer to Figure 6 As shown, in the cross-section along the height direction Z, there is a first constriction 126 between the first protrusion 124 and the second protrusion 21.

[0045] The first narrowing 126 refers to the hooking channel section between the first protrusion 124 and the second protrusion 21, whose width (i.e., the dimension in the front-to-back direction Y) is narrower than other areas. This narrowing structure can be understood as a bottleneck area, which restricts the degree of freedom of the hanging ring 3 in its height direction Z by reducing the size of the channel, thereby improving the anti-slip effect.

[0046] In some embodiments, refer to Figure 6 As shown, the crests of the first protrusion 124 and the second protrusion 21 are offset in the height direction Z. Optionally, the distance H between the crests of the first protrusion 124 and the second protrusion 21 in the height direction Z is 3~5mm, as shown. Figure 7 As shown.

[0047] The crest refers to the point where the protrusion extends to its maximum height into the mounting channel 123. When the crests of these two protrusions are not at the same vertical height, a misaligned staggered arrangement is formed. For example, as shown... Figure 6 As shown, in the height direction Z, the peak height of the first protrusion 124 is the same as the peak height of the second protrusion 21.

[0048] Understandably, although there is a first constriction 126 between the first protrusion 124 and the second protrusion 21, due to the staggered crest design, when the lifting ring 3 is inserted into the hook channel 123 along the height direction Z, it will not simultaneously overcome the resistance of the two protruding parts at their maximum protrusion. For example, when the lifting ring 3 first contacts the crest of the first protrusion 124, the corresponding inclined wall section of the second protrusion 21 has not yet reached the maximum protrusion of the second protrusion 21. Therefore, the deformation required for the spring piece 2 is relatively small. As the lifting ring 3 continues to descend, after passing the first crest, it gradually passes through the second crest area. The force is applied in stages, avoiding the occurrence of instantaneous high resistance peaks. The disassembly process is similar; the reverse operation only requires overcoming the protrusions one by one, rather than simultaneously breaking through the double peak limit. Furthermore, despite the crest misalignment, the lifting ring 3 will still be blocked by the two protrusions in turn during its overall upward movement.

[0049] Therefore, the embodiment of this application, through the design of the staggered peaks of the protrusions, can ensure the anti-slip function while allowing the lifting ring 3 to overcome the elastic resistance of a single protrusion step by step during installation and disassembly. This avoids the problem of laborious operation or jamming caused by simultaneous squeezing from both sides, reduces assembly difficulty, and significantly improves the user experience.

[0050] In some embodiments, refer to Figures 6 to 8 As shown, the limiting part 122 is also provided with a third protrusion 127 located in the hooking channel 123. The third protrusion 127 and the first protrusion 124 are distributed along the height direction Z. The third protrusion 127 is used to prevent the hooking ring 3 from coming out of the hooking channel 123 along the height direction Z when the hooking ring 3 is hooked in the hooking channel 123.

[0051] The third protrusion 127 is located on the limiting portion 122. This protrusion extends into the hook-up channel 123, forming a barrier to the release of the lifting ring 3. The third protrusion 127 can be welded or integrally formed on the limiting portion 122. As an example, Figure 2 and Figure 6 As shown, the limiting portion 122 can be stamped to form a third protrusion 127 on the limiting portion 122. The structure of the first protrusion 124 and the third protrusion 127 can be the same. The first protrusion 124 and the third protrusion 127 are arranged along the height direction Z to form a gradient barrier. Optionally, the first protrusion 124 and the third protrusion 127 are arranged continuously, that is, the first protrusion 124 and the third protrusion 127 are connected, thereby forming a wave-shaped protrusion structure on the hook limiting portion 122. Of course, more protrusion structures can be provided on the hook limiting portion 122 according to actual needs.

[0052] In this embodiment, a third protrusion 127 is added to the limiting part 122, which is distributed along the height direction Z with the first protrusion 124, to construct a multi-obstruction structure on the same side. In conjunction with the second protrusion 21 on the spring piece 2, multiple anti-detachment measures can be achieved, which improves the stability of the hanging ring 3 in the hooking channel 123.

[0053] In some embodiments, refer to Figure 6 As shown, in the cross-section along the height direction Z, there is a second constriction 128 between the third protrusion 127 and the spring piece 2.

[0054] The second narrowing 128 refers to the hooking channel portion between the third protrusion 127 and the spring piece portion located within the hooking channel 123, whose width (i.e., the dimension in the front-to-back direction Y) is narrower than other areas. This narrowing structure can be understood as a bottleneck area, which restricts the degree of freedom of the hanging ring 3 in its height direction Z by reducing the size of the channel, thereby improving the anti-slip effect.

[0055] In some embodiments, refer to Figure 6 As shown, in the height direction Z, the peak of the first protrusion 124 is higher than the peak of the second protrusion 21, and the peak of the third protrusion 127 is higher than the peak of the first protrusion 124. When the hanging ring 3 attempts to come off, it will be hindered by the protrusions of different heights, thus achieving multi-layer anti-slip.

[0056] like Figure 6 As shown, in the normal hanging state, the second protrusion 21 directly contacts and abuts against one side surface of the hanging ring 3 to achieve the limiting function; the first constriction 126 is formed by the relative protrusion of the first protrusion 124 and the second protrusion 21, which is the first bottleneck area in the running path of the hanging ring 3; the second constriction 128 is formed between the third protrusion 127 at a higher position and the spring piece part located in the hanging channel 123, forming a narrowing of the upper channel, which serves as the last limiting barrier to prevent the ring from falling off. The two constrictions are staggered in the height direction Z to form a double neck channel structure, which effectively improves the overall anti-fall effect.

[0057] Understandably, since the first narrowing 126 is formed by two protrusions, while the second narrowing 128 is formed by one protrusion, the width of the second narrowing 128 can be greater than the width of the first narrowing 126. Figure 6 As shown. This design makes the second constriction 128 at the top opening adjacent to the hook channel 123 relatively large, which facilitates the insertion of the lifting ring 3. Furthermore, the resistance of the lifting ring 3 passing through the second constriction 128 is less than the resistance passing through the first constriction 126. Thus, when removing the lifting ring 3, the force required decreases as you go higher, thereby improving the ease of operation.

[0058] In some embodiments, refer to Figure 1 and Figure 2As shown, the limiting part 122 has a set of first protrusions 124 and a third protrusion 127 on both sides along the horizontal direction X, and the spring piece 2 and the second protrusion 21 are located between the two sets of first protrusions 124 and third protrusions 127 in the horizontal direction X. This layout can further enhance the stability and anti-detachment effect when the lifting ring 3 is engaged by increasing the number of lateral limiting protrusions.

[0059] In some embodiments, refer to Figure 6 and Figure 7 As shown, in at least one of the protrusions, the first protrusion 124, the second protrusion 21, and the third protrusion 127, the protrusion includes a first inclined wall 51 and a second inclined wall 52. The first inclined wall 51 is connected to the side of the second inclined wall 52 away from the mounting part 121. The first inclined wall 51 and the second inclined wall 52 have an included angle, and the first inclination angle of the first inclined wall 51 relative to the height direction Z is smaller than the second inclination angle of the second inclined wall 52 relative to the height direction Z.

[0060] For example, each protrusion may be composed of a first inclined wall 51 and a second inclined wall 52, which are connected at the apex to form a V-shaped cross section. The first inclined wall 51 is located above and serves as the guide surface that the lifting ring 3 contacts when it is inserted. The second inclined wall 52 is located below and serves as the obstruction surface that the lifting ring 3 must overcome when it attempts to detach. The first inclined wall 51 has a smaller first angle (e.g., 30°~50°) to facilitate guidance, while the second inclined wall 52 has a larger second angle (e.g., 70°~85°, close to vertical) to form a steep obstruction.

[0061] When the lifting ring 3 is inserted into the hanging channel 123 from top to bottom, it contacts the raised first inclined wall 51. Because the inclination angle of this inclined wall is small, it forms a long inclined transition area, allowing the lifting ring 3 to smoothly push away the spring piece 2 and the hook limiting part 122 during the downward process, reducing the installation resistance, and the display device can be hooked in by its own weight. When the lifting ring 3 attempts to come out upward due to vibration or external impact, it contacts the raised second inclined wall 52. Because this inclined wall is steeper than the first inclined wall 51, it increases the resistance to coming out, thereby effectively preventing the display device from accidentally falling off.

[0062] The first tilt angle of the first inclined wall 51 can be described as the insertion angle 'a', and the second tilt angle of the second inclined wall 52 can be described as the disassembly angle 'b'. In actual design, the disassembly force can be made greater than the weight of the display device by designing the insertion and disassembly angles, thereby further improving the anti-detachment effect. During insertion, the display device can be smoothly hooked in by its own weight.

[0063] In some embodiments, the insertion angle a is 40°~50° and the disassembly angle b is 75°~85°.

[0064] In some embodiments, refer to Figure 7As shown, the second protrusion 21 includes a first inclined wall 51 and a second inclined wall 52, with the second inclined wall 52 abutting against the lifting ring 3.

[0065] This application embodiment achieves an anti-detachment mechanism that saves effort during installation and makes disassembly difficult by setting an inclined wall structure with an asymmetrical tilt angle on the protruding structure, thereby improving the ease of installation and anti-detachment performance.

[0066] In some embodiments, refer to Figure 1 , Figures 6 to 8 As shown, one side of the lifting ring 3 can rotate relative to the hanging part 121 so that the lifting ring 3 can swing towards or away from the main body 11; the second bracket 4 has a rotating side 42, which is rotatably connected to the other side of the lifting ring 3; the bottom side of the main body 11 is provided with a stop part 114 for stopping above the rotating side 42.

[0067] The upper and lower sides of the hanging ring 3 are rotatably connected to the mounting part 121 and the second bracket 4, respectively. This increases the distance between the display device and the wall, provides more operating space, and facilitates the installation and removal of the hanging ring 3.

[0068] The stop part 114 is located on the bottom side of the main body 11. When the lifting ring 3 is fully engaged and in a vertical engagement state, the rotating side 42 of the second bracket 4 moves to below the stop part 114 of the main body. This prevents the lifting ring 3 from moving upward and detaching from the engagement channel 123 due to external forces, thus improving the anti-detachment effect. Figure 6 As shown. In some examples, the stop 114 can be a protrusion or a flange, etc. The stop 114 can be welded or integrally formed onto the body 11. As an example, such as Figure 2 and Figure 6 As shown, two vertical cutting lines can be provided along the bottom edge of the main body 11, and then the main body portion between the two cutting lines is bent forward to a horizontal state, thereby forming the stop portion 114. This design makes full use of the structure of the main body 11 itself, eliminating the need for additional stop components, resulting in a simple structure and cost savings. The number of stop portions 114 can be designed according to actual needs, and can be one or more.

[0069] In some embodiments, refer to Figure 1 , Figure 4 and Figure 5As shown, the rotating side 42 of the second support 4 is provided with a first lug 43 and a second lug 44. The first lug 43 and the second lug 44 have an included angle and are located on the front and rear sides of the lower side of the lifting ring 3, respectively. For example, the first lug 43 and the second lug 44 are located on the front and rear sides of the extension end 31 of the lifting ring 3. The included angle between the first lug 43 and the second lug 44 is 90°. The first lug 43 is vertically arranged, and the second lug 44 is horizontally arranged. When the lifting ring 3 rotates relative to the second support 4, the extension end 31 of the lifting ring 3 stops between the first lug 43 and the second lug 44. In this embodiment, the first lug 43 and the second lug 44 can limit the rotation stroke of the lifting ring 3, so that the lifting ring 3 can rotate within a set stroke range.

[0070] In some embodiments, this application also provides a display device, including: a display unit and a wall-mounted structure as described in the above embodiments, wherein the main body 11 of the first bracket 1 is used for mounting on a wall, and the display unit is connected to the second bracket 4. The display unit can be an LCD TV, a monitor, etc.

[0071] When installing the display device, the user lifts the display device and inserts the hanging ring 3, which is mounted on the second bracket 4 on the back of the display device, into the hook 12 of the first bracket 1 on the wall. When the hanging ring 3 falls onto the hanging part 121 of the hook 12, the hanging ring 3 can rotate under the weight of the display device, causing the rotating side 42 of the second bracket 4 to return to the bottom of the stop part 114 of the main body 11. The stop part 114 acts as a limit, preventing the hanging ring 3 from accidentally moving upward. At this time, the wall-mounted structure is in a vertical hanging state. Figure 6 As shown.

[0072] When the display device needs to be disassembled, the user lifts the display device and rotates the lifting ring 3 forward around the mounting part 121. When it rotates to... Figure 7 In the first lifting state shown, the rotating side 42 of the second bracket 4 has not yet left the stopping range of the stop part 114. The stop part 114, the protruding structure on the hook limiting part 122, and the protruding structure on the spring piece 2 can work together to prevent detachment.

[0073] As the ring 3 continues to rotate forward... Figure 8 In the second lifting state shown, the rotating side 42 of the second bracket 4 is disengaged from the stop range of the stop part 114, and then the display device is lifted upward to overcome the resistance of the protruding structure on the hook limiting part 122 and the protruding structure on the spring piece 2, thereby removing the hanging ring 3 from the hooking channel 123 and completing the removal of the display device.

[0074] It is understandable that in this application, the lifting ring 3 is vertically installed in the normal hanging state. When the user attempts to lift the display device upward along the height direction Z, the lifting ring 3 will deflect due to the connecting structure, forming an inclined state with a rotation angle d relative to the height direction Z. At this time, the effective component F1 of the vertical disassembly force F applied by the user (corresponding to the hypotenuse of the dotted line in the figure) in the axial direction of the lifting ring 3 is F×cosd (corresponding to the right-angled side of the dotted line near the rotation angle d in the figure). Figure 8 As shown, under the premise that the wall-mounted structure remains unchanged, the structural resistance F2 (including the protruding limiting resistance of the hook and spring plate) that the lifting ring 3 needs to overcome to detach is basically fixed. For the lifting ring 3 to detach, the following must be satisfied: F1 = F × cosd ≥ F2, that is, F ≥ F2 / cosd. As d increases, cosd decreases, and the required disassembly force F increases, thus requiring a larger external force to achieve detachment, which significantly improves the anti-detachment safety of the wall-mounted structure in the event of accidental lifting.

[0075] Therefore, the display device provided in this application embodiment, through the wall-mounted structure of the above embodiment, can improve the anti-fall effect of the display device, reduce the risk of accidental fall, and improve the safety of use.

[0076] The above are merely preferred embodiments of this application and are not intended to limit the embodiments of this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the embodiments of this application should be included within the protection scope of the embodiments of this application.
