Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of household appliances, and in particular to a wall-mounted display device. BACKGROUND

[0002] In order to save space and ensure the aesthetics of the room, more and more users choose to hang the display device on the wall. Taking a flat-panel television as an example, with the flat-panel television becoming thinner and thinner, the demand for hanging the flat-panel television is also increasing.

[0003] In the related art, the wall mounting structure of the flat-panel television generally includes a flat-panel television side support and a wall side support. The wall side support is provided with a hook, and the flat-panel television side support is rotatably provided with a hanging ring. The hanging ring is detachably hung on the hook to realize the hanging of the flat-panel television on the wall.

[0004] However, in order to provide damping force for the hanging ring and enable the hanging ring to be kept at a proper angle for the hanging of the flat-panel television, the damping design of the current wall mounting structure is complex and is not conducive to the thinning of the wall mounting structure, resulting in an excessively large distance between the flat-panel television and the wall. CONTENT OF THE INVENTION

[0005] The embodiments of the present application disclose a wall-mounted display device, which can more conveniently install the hanging ring and simplify the overall structure of the wall mounting structure, and is more conducive to the thinning of the wall mounting structure.

[0006] In order to achieve the above-mentioned purpose, the embodiments of the present application disclose a wall-mounted display device, which comprises:

[0007] a display device;

[0008] a wall mounting structure configured to hang the display device on a wall;

[0009] The wall mounting structure comprises:

[0010] a first support comprising:

[0011] a frame body configured to be arranged on the wall;

[0012] a hook arranged on the frame body;

[0013] a second support comprising:

[0014] a connecting plate connected to the display device;

[0015] a hanging ring, one end of which is rotatably connected to the connecting plate, and the other end of which is detachably hung on the hook to hang the display device on the wall;

[0016] The rotating connection between the hanging ring and the connecting plate is provided with a protruding part configured to provide a force to keep the hanging ring in the current position when the hanging ring rotates to any angle relative to the connecting plate.

[0017] The wall-mounted display device provided in the present application can make the rotating connection between the hanging ring and the connecting plate form an interference fit by setting a protruding part between the connecting plate and the hanging ring of the second bracket, thereby providing a force to keep the hanging ring in the current position when the hanging ring rotates to any angle relative to the connecting plate. In this way, when the hanging ring is rotated to a certain angle with the connecting plate and hung on the hook, the hanging ring can be kept in this position and will not rotate easily, which can make it more convenient to hang the hanging ring, thereby improving the convenience of installing the display device. In addition, by setting the protruding part for providing damping at the rotating connection between the connecting plate and the hanging ring, it is not necessary to additionally set a damping structure, which simplifies the overall structure of the wall-mounted structure and does not excessively occupy the space between the display device and the wall, thereby facilitating the reduction of the overall thickness of the wall-mounted structure, reducing the distance between the display device and the wall, and making the display device better adhere to the wall.

[0018] As an optional implementation, the connecting plate is formed with an axle hole, the hanging ring can be rotatably arranged in the axle hole, and the axle hole is provided with an inner wall surface, and the inner wall surface of the axle hole is provided with the protruding part.

[0019] The axle hole is formed on the connecting plate for the hanging ring to pass through, and the protruding part is formed on the inner wall surface of the axle hole formed on the connecting plate, which is more reasonable in structure layout and easier to realize in the process of molding.

[0020] As an optional implementation, the protruding part is a hemispherical protrusion, and a plurality of the protruding parts are arranged along the axial direction of the axle hole and / or the circumferential direction of the axle hole.

[0021] By setting the protruding part as a hemispherical protrusion, it can be ensured that the protruding part has sufficient contact area with the inner wall surface of the axle hole, and the rotation of the hanging ring can be effectively supported by the protruding part to avoid excessive stress of the hanging ring on the protruding part and effectively avoid deformation of the protruding part. In addition, since a plurality of protruding parts are arranged along the axial direction of the axle hole and / or the circumferential direction of the axle hole, effective damping force can be provided to keep the position of the hanging ring, which facilitates the hanging of the hanging ring on the hook while ensuring that the hanging ring partially contacts the inner wall surface of the axle hole and partially retains a gap, thereby avoiding excessive rotation resistance and facilitating smooth rotation of the hanging ring.

[0022] As an optional implementation, the bracket body part has a top end in the first direction, and the hook is arranged at the top end.

[0023] The first support further comprises:

[0024] A limiting member is arranged at the top end of the frame body part, and is configured to limit the position of the hanging ring in the first direction when the hanging ring is hung on the hook.

[0025] The first direction is the height direction of the wall.

[0026] Since the hanging ring is not completely constrained in the first direction (i.e., the height direction of the wall) after being hung on the hook, it may be possible to shake up and down. Therefore, by arranging a limiting member on the frame body part, the position of the hanging ring in the first direction is limited by the limiting member when the hanging ring is hung on the hook, thereby effectively constraining the hanging ring in the up-down direction, preventing the hanging ring from moving in the up-down direction, and preventing the hanging ring from falling off the hook, thereby improving the reliability of the hanging ring hung on the hook, and further ensuring the reliability of the display device hung on the wall.

[0027] In addition, by arranging the hook and the limiting member at the top end of the frame body part, when the hanging ring is hung on the hook, compared with arranging the hook at the middle or bottom of the frame body part, the space for the hanging ring to be hung is only between the frame body part and the hook, so that a hanging space for the hanging ring to be hung is formed between the wall and the hook, which includes the thickness space of the frame body part, so that the hanging space is larger, and the hanging ring can more easily enter the hanging space and be hung on the hook.

[0028] As an optional implementation, the second support further comprises:

[0029] A magnetic member is arranged on the connecting plate and corresponds to the connection between the hanging ring and the connecting plate, and is configured to be adsorbed to the frame body part.

[0030] In this way, after the hanging ring is hung on the hook, the adsorption of the magnetic member and the frame body part can ensure that the second support as a whole can remain in the state of being attached to the first support, and the first support and the second support are not easily separated due to external interference, thereby ensuring the stability of the display device when it is hung and the attachment to the wall. In addition, the magnetic member is arranged at the rotating connection between the hanging ring and the connecting plate, which is approximately at both ends of the hanging ring in the first direction, so that the verticality of the hanging ring in the hanging state and the attachment to the first support can be more effectively ensured, and the hanging ring and the connecting plate are prevented from easily rotating.

[0031] As an optional implementation, the thickness of the limiting member is less than or equal to the thickness of the frame body part, so that the projection of the limiting member in a preset plane is within the projection range of the frame body part in the preset plane.

[0032] The preset plane is parallel to the first direction and the thickness direction of the frame body part.

[0033] By limiting the relationship between the thickness of the limiting member and the thickness of the frame body part, and making the projection of the limiting member in the preset plane parallel to the height of the wall and the thickness direction of the frame body part fall within the projection range of the frame body part, the thickness space of the limiting member coincides with the thickness space of the frame body part, that is, the limiting member is arranged within the thickness space of the frame body part without increasing the overall thickness of the first support. Thus, the thickness of the first support can be thinner, which is beneficial to the lightness and thinness of the overall structure of the wall-mounted structure, and further beneficial to reducing the distance between the display device and the wall, and better achieving the wall-hugging effect of the display device.

[0034] As an optional implementation, the frame body part includes a first surface and a second surface along the thickness direction, the first surface is configured to be close to one side of the display device, and the second surface is configured to be close to one side of the wall.

[0035] The second surface is provided with a groove, and the limiting member is arranged in the groove. The outer surface of the limiting member is lower than the second surface or flush with the second surface.

[0036] By forming a groove on the second surface of the frame body part close to the wall for the arrangement of the limiting member, the limiting member can be arranged in the thickness space of the frame body part, and the thickness space of the limiting member and the thickness space of the frame body part are multiplexed. In addition, the structure is simple and easy to implement.

[0037] As an optional implementation, the frame body part includes a first surface and a second surface along the thickness direction, the first surface is configured to be close to one side of the display device, and the second surface is configured to be close to one side of the wall.

[0038] The hook includes:

[0039] A first section, the first section is protruded on the first surface;

[0040] A second section, the second section is connected to the first section, and the second section extends upward along the first direction to form a space for the hanging ring to be arranged, and the second section is configured to limit the position of the hanging ring in the second direction;

[0041] The size of the first section in the second direction is less than or equal to the size of the hanging ring in the second direction.

[0042] The first direction is the height direction of the wall body, and the second direction is the thickness direction of the frame body part.

[0043] By dividing the hook into a first segment protruding from the first surface and a second segment extending in the first direction, and limiting the size of the first segment in the second direction to be less than or equal to the size of the ring in the second direction, when the size of the first segment in the second direction (the thickness direction of the frame body part) is equal to the size of the ring in the second direction, the ring can be just hung on the first segment, so that the overall thickness of the wall hanging structure is the sum of the thickness of the frame body part, the size of the ring, and the size of the second segment, at this time the maximum thickness of the wall hanging structure can be achieved; when the size of the first segment in the second direction is less than the size of the ring in the second direction, the ring will be hung on the frame body part in addition to the first segment in the hung state, so that the overall thickness of the wall hanging structure is the sum of the partial thickness of the frame body part, the size of the ring, and the size of the second segment, at this time the overall thickness of the wall hanging structure can be further reduced, which is more beneficial to the thinning effect of the wall hanging structure.

[0044] As an optional implementation, the size of the frame body part in the second direction is T1, and the size of the second segment in the second direction is T2, T2≤T1.

[0045] Since the sizes of the frame body part and the second segment in the second direction constitute two parts of the overall thickness of the wall hanging structure, and the second segment provides a hanging space for the ring and limits the position of the ring in the second direction, by limiting the size of the second segment in the second direction to be less than or equal to the size of the frame body part in the second direction, the relationship is satisfied, the size of the second segment is made smaller under the premise of meeting the structural strength, which is more beneficial to the thickness reduction of the wall hanging structure.

[0046] As an optional implementation, the size of the frame body part in the second direction T1≥1.2mm; and / or,

[0047] The size of the second segment in the second direction T2≥1.2mm; and / or,

[0048] The size of the ring in the second direction T3≥4mm.

[0049] By satisfying the above relationship, the sizes of each component of the wall hanging structure in the second direction can be made small enough, so that the overall thickness of the wall hanging structure can be made to be the thinnest 6.4mm, and the structural strength of each component can be effectively guaranteed. If the above parameters are too small, the structural strength of each component cannot be guaranteed, which affects the structural mechanical properties of the wall hanging structure.

[0050] Compared with the prior art, the application has the beneficial effects that:

[0051] The wall-mounted display device provided by the application can form interference fit at the rotating connection between the hanging ring and the connecting plate of the second support, so as to provide a force for keeping the hanging ring at the current position when the hanging ring rotates to any angle relative to the connecting plate. In this way, when the hanging ring is rotated to a certain angle relative to the connecting plate and hung on the hook, the hanging ring can be kept at the position and not easily rotated, which can make it more convenient to hang the hanging ring, thereby improving the convenience of installing the display device. In addition, the protrusion for providing damping is arranged at the rotating connection between the connecting plate and the hanging ring, so that no additional damping structure is needed, the overall structure of the wall-mounted structure is simplified, and the space between the display device and the wall is not excessively occupied, which is beneficial to reducing the overall thickness of the wall-mounted structure, thereby reducing the distance between the display device and the wall, and making the wall sticking effect of the display device better.

[0077] The technical solutions of the present application will be further described below in conjunction with the embodiments and the drawings.

[0078] Referring to Figure 1 The embodiments of the present application disclose a wall-mounted display device 1. The wall-mounted display device 1 can be widely used in homes, offices, conference halls, exhibition halls, stations, hospitals or shopping malls and the like.

[0079] In some embodiments, the wall-mounted display device 1 comprises a display device 100, which can be used to display image information. For example, it can be a television, a liquid crystal display screen or the like electronic display product.

[0080] In some embodiments, the wall-mounted display device 1 comprises a wall-mounted structure 200, which is used to hang the display device 100 on the wall 300. That is, in the use state, the wall-mounted structure 200 is connected between the display device 100 and the wall 300, as an intermediate connecting structure for hanging the display device 100 on the wall 300.

[0081] With the display device 100 hanging on the wall 300 as a reference, the vertical direction is the up-down direction, the direction facing the user is the front, the direction facing away from the user is the back, the thickness of the wall hanging structure 200 is the front-back direction, and the width direction of the display device 100 is the left-right direction.

[0082] Optionally, the number of wall hanging structures 200 can be one, and of course can also include multiple, for example, two, three, or four, etc. Taking two as an example, the two wall hanging structures 200 can be arranged in the left-right direction, to ensure the stability of the display device 100 hanging on the wall.

[0083] Please refer to Figures 2 to 4 In some embodiments, the wall hanging structure 200 includes a first support 10, which can be a support arranged on the wall 300. The first support 10 can be fixedly connected with the wall 300 by screws, bolts, etc. locking members, or can be detachably connected with the wall 300 by hanging or other ways.

[0084] In some embodiments, the wall hanging structure 200 includes a second support 20, which can be a support connected to the display device 100. The second support 20 can be fixedly connected with the display device 100 by screws, bolts, etc. locking members, or can be detachably connected with the display device 100 by hanging or other ways.

[0085] Optionally, the first support 10 and the second support 20 can both be metal supports, so that the wall hanging structure 200 as a whole has sufficient structural strength and good load-bearing capacity.

[0086] In some embodiments, in combination with Figure 3 and Figure 4 The first support 10 includes a support body part 11, which is configured to be arranged on the wall 300. That is, the support body part 11 serves as a connection structure of the entire first support 10 connected to the wall 300, and can be fixed on the wall 300 by screws, bolts, or expansion bolts, etc. fasteners.

[0087] Optionally, the support body part 11 can be a plate structure, a frame structure, etc. Preferably, the support body part 11 can be a plate structure, so that the first support 10 as a whole is more lightweight and has a smaller thickness in the front-back direction, so that the display device is closer to the wall 300. In addition, the shape of the support body part 11 can be, for example, a rectangle, or a polygon such as a pentagon, etc. On the premise that the first support 10 and the wall 300 have sufficient contact area to ensure firm connection between them, the actual needs can be selected, and the specific shape is not limited in the embodiments of the present application.

[0088] It should be noted that the wall 300 has a height direction, which is defined as the first direction Z in the embodiment of the present application, and the thickness direction of the frame body 11 is defined as the second direction Y. It can be understood that the second direction Y can also be the front-rear direction of the display device 100 or the thickness direction of the wall hanging structure 200. That is, the first direction Z is the height direction of the wall 300, and the second direction Y is the thickness direction of the frame body 11.

[0089] In some embodiments, the first support 10 includes a hook 12 arranged on the frame body 11. The hook 12 and the frame body 11 form a hooking position, so that the second support 20 is hung on the hooking position, and the display device 100 is hung on the wall 300.

[0090] Optionally, the frame body 11 of the embodiment of the present application can be a sheet metal part, and the hook 12 can be formed by cutting and bending the frame body 11, so that the frame body 11 and the hook 12 form a hooking position for the second support 20 to be hung on the first support 10.

[0091] In some embodiments, the second support 20 includes a connecting plate 21 connected to the display device 100. That is, the connecting plate 21 is a connecting structure of the entire second support 20 connected to the display device 100, and can be fixed to the display device 100 by screws, bolts or other fasteners. Specifically, the connecting plate 21 is arranged on the back of the display device 100, that is, the side of the display device 100 facing the wall 300.

[0092] In some embodiments, the second support 20 includes a hanging ring 22, one end of which is rotatably connected to the connecting plate 21, and the other end of which is detachably hung on the hook 12 to hang the display device 100 on the wall 300.

[0093] It can be understood that the hanging ring 22 can be a closed or semi-closed ring structure, and its shape can be circular, square, polygonal or the like.

[0094] In some embodiments, the hanging ring 22 can be a semi-closed square hanging ring 22, which has opposite two ends along the first direction Z in the use state, the lower end being a rotating end 22a rotatably connected to the connecting plate 21, and the upper end being a hooking end 22b detachably connected to the hook 12. The lower end can have a break to make the hanging ring 22 a semi-closed hanging ring 22, and the break makes it more convenient to be rotatably connected to the connecting plate 21.

[0095] In some embodiments, the second support 20 includes a hanging ring 22, one end of which is rotatably connected to the connecting plate 21, and the other end of which is detachably hung on the hook 12 to hang the display device 100 on the wall 300. Figure 4 and Figure 5, the hanging ring 22 includes an unfolded state in which the hanging ring 22 forms an angle with the first support 10, and the display device 100 has not yet been completely attached to the wall 300, and an attached state in which the hanging ring 22 is parallel to the first support 10, and the display device 100 is installed in place and hung on the wall 300.

[0096] Specifically, when the display device 100 is hung on the wall 300, the hanging ring 22 can be located on the side of the frame body 11 facing the display device 100, and the hanging ring 22 is in an attached state with the frame body 11. At this time, the hanging ring 22 is arranged substantially parallel to the frame body 11, so that the second support 20 is closely arranged with the first support 10, so that the overall structure of the wall hanging structure 200 is more compact, thereby making the distance between the display device 100 and the wall 300 smaller.

[0097] Optionally, the connecting plate 21 of the second support 20 can be made of sheet metal, and the hanging ring 22 can be made of metal materials such as stainless steel.

[0098] Since the hanging ring 22 is rotationally connected with the connecting plate 21, in the initial state of installation, a suitable angle is formed between the hanging ring 22 and the connecting plate 21, and then the display device 100 is lifted and approached to the wall 300 side, and the hanging ring 22 is gradually hung on the hook 12. If the hanging ring 22 always rotates relative to the connecting plate 21 during this process and cannot be stably maintained at the current angle position, it will cause great difficulty in installation.

[0099] Based on this, in some embodiments, referring to Figure 5 , the rotation connection between the hanging ring 22 and the connecting plate 21 is provided with a protruding portion 23, which is configured to provide a force for maintaining the current position when the hanging ring 22 rotates relative to the connecting plate 21 to any angle.

[0100] The wall-mounted display device 1 provided in the present application can form interference fit at the rotating connection between the hanging ring 22 and the connecting plate 21 of the second support 20, so as to provide force for keeping the hanging ring 22 at the current position when the hanging ring 22 is rotated to any angle relative to the connecting plate 21. In this way, when the hanging ring 22 is rotated to a certain angle relative to the connecting plate 21 and hung on the hook 12, the hanging ring 22 can be kept at the position and not easily rotated, which can make it more convenient to hang the hanging ring 22, thereby improving the convenience of installing the display device. In addition, by arranging the protrusion 23 for providing damping at the rotating connection between the connecting plate 21 and the hanging ring 22, the damping structure does not need to be additionally arranged, the overall structure of the wall hanging structure 200 is simplified, and the space between the display device and the wall 300 is not excessively occupied, which is beneficial to reducing the overall thickness of the wall hanging structure 200, thereby reducing the distance between the display device and the wall 300, and making the display device better adhere to the wall.

[0101] It can be understood that after the hanging ring 22 is hung on the hook 12 at a certain angle, the display device 100 is still lifted, and the hanging ring 22 and the first support 10 are in an unfolded state with an included angle (as shown in Figure 6 At this time, the second support 20 and the first support 10 have a gap, which provides sufficient space for disassembling and adjusting the second support 20 and sufficient space for inserting wires and other operations of the display device 100.

[0102] In some embodiments, in combination with Figure 6 and Figure 7 The connecting plate 21 is provided with an axis hole 211, the hanging ring 22 can be rotatably arranged in the axis hole 211, and the axis hole 211 is provided with an inner wall surface 211a, and the inner wall surface 211a of the axis hole 211 is provided with the protrusion 23.

[0103] Optionally, the connecting plate 21 can include a plurality of axis holes 211, and the plurality of axis holes 211 can be formed on the connecting plate 21 by bending, and the plurality of axis holes 211 are arranged at intervals, so as to ensure the reliability of the rotating connection between the hanging ring 22 and the connecting plate 21.

[0104] The axis hole 211 is formed on the connecting plate 21 to allow the hanging ring 22 to pass through, and the protrusion 23 is formed on the inner wall surface 211a of the axis hole 211 formed on the connecting plate 21, so that the structure layout is more reasonable and easier to realize in the processing and forming process.

[0105] In some embodiments, the protrusion 23 is a hemispherical protrusion, which can provide damping force for the rotation of the hanging ring 22 and facilitate the rotation of the hanging ring 22.

[0106] In some embodiments, the number of protrusions 23 is multiple, and the multiple protrusions 23 are arranged along the axial direction of the shaft hole 211 and / or the circumferential direction of the shaft hole 211.

[0107] It is worth noting that the rotating end 22a of the hanging ring 22 is a long rod-shaped rotating shaft, and the shaft hole 211 matched therewith is a long strip-shaped through hole. Along the axial direction of the shaft hole 211, the inner wall surface 211a of the shaft hole 211 can be provided with multiple rows of protrusions 23, and the multiple rows of protrusions 23 are arranged along the circumferential direction of the shaft hole 211. It can be understood that the protrusions 23 are arranged in uniform rows. Of course, in other embodiments, the multiple protrusions 23 can also be arranged in non-uniform rows, as long as sufficient damping force is provided for the rotation of the hanging ring 22.

[0108] By arranging the protrusions 23 as semispherical protrusions, sufficient contact area can be ensured between the protrusions 23 and the inner wall surface 211a of the shaft hole 211, and the rotation of the hanging ring 22 can be effectively supported by the protrusions 23, so as to avoid excessive stress on the protrusions 23 and effectively avoid deformation of the protrusions 23. In addition, since the multiple protrusions 23 are arranged along the axial direction of the shaft hole 211 and / or the circumferential direction of the shaft hole 211, effective damping force can be provided to maintain the position of the hanging ring 22, facilitate the hanging of the hanging ring 22 on the hook 12, and at the same time, ensure that the hanging ring 22 is partially in contact with the inner wall surface 211a of the shaft hole 211 and partially retains a gap, so as not to cause excessive rotation resistance and be more conducive to smooth rotation of the hanging ring 22.

[0109] During installation, the first support 10 is first fixedly connected with the wall 300, and the second support 20 is fixedly connected with the display device 100, and then the hanging ring 22 is connected with the connecting plate 21. Figure 2 and Figure 5 The hanging ring 22 is rotated to a suitable angle (for example, the included angle between the hanging ring 22 and the connecting plate 21 is 90°) relative to the connecting plate 21, and the hanging ring 22 can be maintained at this position under the action of the protrusions 23, then the hanging ring 22 is moved close to the hook 12 and hung on the hook 12. The hanging ring 22 hung on the hook 12 can be reversely rotated around the axis of the shaft hole 211 under the action of the gravity of the display device, and the second support 20 is moved close to the first support 10 until the second support 20 is attached to the first support 10, thereby completing the installation of the display device 100.

[0110] In some embodiments, the frame body 11 has a top end 11a in the first direction Z, and the hook 12 is arranged at the top end 11a, which is more convenient for the installation of the hanging ring 22.

[0111] When the hook 12 is integrally formed with the frame body 11, for example, the frame body 11 is a sheet metal part, and the hook 12 is formed by stamping and bending. Since the hook 12 is formed at the top end 11a of the frame body 11, it is more convenient for forming processing.

[0112] Since the hanging ring 22 is not completely constrained in the first direction Z (i.e., the height direction of the wall body 300) after being hung on the hook 12, there may be a situation of up and down shaking under the action of external force.

[0113] Based on this, in some embodiments, continuing to refer to Figure 3 and Figure 4 and Figure 8 , the first support 10 further comprises a limiting piece 13, which is arranged at the top end 11a of the frame body 11. In the state that the hanging ring 22 is hung on the hook 12, the limiting piece 13 is configured to limit the position of the hanging ring 22 in the first direction Z. The first direction Z is the height direction of the wall body 300.

[0114] By arranging the limiting piece 13 on the frame body 11, in the state that the hanging ring 22 is hung on the hook 12, the position of the hanging ring 22 in the first direction Z is limited by the limiting piece 13, which effectively constrains the hanging ring 22 in the up and down direction. In this way, the situation that the hanging ring 22 moves up and down is prevented, and the hanging ring 22 is prevented from being pulled out of the hook 12, thereby facilitating the reliability of the hanging ring 22 hung on the hook 12, and further ensuring the reliability of the display device 100 hung on the wall body 300.

[0115] In addition, by arranging the hook 12 and the limiting piece 13 at the top end 11a of the frame body 11, when the hanging ring 22 is hung on the hook 12, compared with the case that the hook 12 is arranged at the middle or bottom of the frame body 11, and the space for the hanging ring 22 to be hung is only between the frame body 11 and the hook 12, a hooking space for the hanging ring 22 to be hung is formed between the wall body 300 and the hook 12, which includes the thickness space of the frame body 11, so that the hooking space is larger, and the hanging ring 22 can more easily enter the hooking space and be hung on the hook 12.

[0116] Optionally, the limiting piece 13 can be a metal sheet with elasticity, such as a spring, and an arched portion 131 protruding towards the side of the display device 100 is formed at the position close to the top end 11a in the first direction Z. When the hanging ring 22 is hung, the limiting piece 13 can be deformed under the gravity of the display device 100 to make the hanging ring 22 be clamped in, and finally be connected with the hook 12. The arched portion 131 limits the position of the hanging ring 22. When the display device 100 is subjected to external force, the hanging ring 22 can be prevented from being easily pulled out of the hook 12, thereby preventing the display device 100 from falling.

[0117] In some embodiments, in combination with Figure 4 , the second support 20 further comprises a magnetic attraction piece 24, which is arranged on the connecting plate 21 and corresponds to the connection between the hanging ring 22 and the connecting plate 21. The magnetic attraction piece 24 is configured to be attracted to the frame body 11.

[0118] Optionally, the magnetic member 24 can be a magnet or other metal material with magnetism.

[0119] It is worth noting that when the second support 20 is attached to the first support 10, the position of the magnetic member 24 attached to the shelf part 11 is close to the bottom of the shelf part 11 along the first direction Z, so that the top of the second support 20 is connected by the hook 12 and the hanging ring 22, and the bottom is fixedly connected by the magnetic member 24, thereby improving the stability of the connection between the two.

[0120] In this way, after the hanging ring 22 is hung on the hook 12, the second support 20 can be kept in the state of being attached to the first support 10 by the magnetic attraction between the magnetic member 24 and the shelf part 11, and the first support 10 and the second support 20 are not easily separated due to external interference, thereby ensuring the stability of the display device 100 when it is hung and the attachment to the wall 300. In addition, the magnetic member 24 is arranged at the position where the hanging ring 22 and the connecting plate 21 are rotatably connected, which is approximately at the two ends of the hanging ring 22 along the first direction Z, and the position where the hanging ring is separably hung on the hook. This can more effectively ensure the perpendicularity of the hanging ring 22 in the hanging state and the attachment to the first support 10, and prevent the hanging ring 22 and the connecting plate 21 from easily rotating.

[0121] In some embodiments, the shelf part 11 of the first support 10 can be made of metal material, so that the magnetic member 24 of the second support 20 can be directly attached to the shelf part 11 without the need for an additional magnetic member 24 on the shelf part 11 of the first support 10, thereby not increasing the overall thickness of the first support 10 and causing the thickness of the wall-mounted structure 200 to be too thick.

[0122] Optionally, the number of magnetic members 24 can include multiple magnetic members 24 arranged along the axial direction of the shaft hole 211, thereby improving the attraction force between the second support 20 and the first support 10 and improving the reliability of the connection between the second support 20 and the first support 10.

[0123] In some embodiments, referring to Figure 9 and Figure 10 , the thickness of the limiting member 13 is less than or equal to the thickness of the shelf part 11, so that the projection of the limiting member 13 in the preset plane O is within the projection range of the shelf part 11 in the preset plane O. The preset plane O is parallel to the first direction Z and the thickness direction of the shelf part 11.

[0124] It can be understood that the preset plane O is an imaginary plane parallel to the height direction of the wall 300 and the front-back direction of the display device 100.

[0125] It should be noted that the projection of the limiting piece 13 in the preset plane O is located in the projection range of the bracket body 11 in the preset plane O, which means that the projection shape of the bracket body 11 in the preset plane O has a first edge 11b close to the wall 300 and a second edge 11c close to the display device 100, and the projection shape of the limiting piece 13 in the preset plane O has a third edge 13a close to the wall 300 and a fourth edge 13b close to the display device 100, wherein the third edge 13a does not exceed the range of the first edge 11b, and the fourth edge 13b does not exceed the range of the second edge 11c. That is, no matter how the limiting piece 13 is arranged in the left-right direction, the space occupied by the limiting piece 13 in the front-rear direction always falls within the space range occupied by the bracket body 11 in the front-rear direction.

[0126] In addition, the thickness of the limiting piece 13 can refer to the size of the limiting piece 13 in the second direction Y. When the limiting piece 13 is irregularly shaped, the thickness of the limiting piece 13 is variable, and the size can be the maximum size. Correspondingly, the thickness of the bracket body 11 can refer to the size of the bracket body 11 in the second direction Y. When the bracket body 11 is irregularly shaped, the thickness of the bracket body 11 is variable, and the size can be the maximum size.

[0127] By limiting the relationship between the thickness of the limiting piece 13 and the thickness of the bracket body 11, and making the projection of the limiting piece 13 fall within the projection range of the bracket body 11 in the preset plane O parallel to the height of the wall 300 and the thickness direction of the bracket body 11, the thickness space of the limiting piece 13 coincides with the thickness space of the bracket body 11, that is, the limiting piece 13 is arranged within the thickness space range of the bracket body 11, without increasing the overall thickness of the first support 10. Therefore, the thickness of the first support 10 can be made thinner, thereby facilitating the thinning of the overall structure of the wall-mounted structure 200, and further facilitating the reduction of the distance between the display device 100 and the wall 300, and better achieving the wall-hugging effect of the display device 100.

[0128] In some embodiments, the bracket body 11 includes a first surface 111 and a second surface 112 in the thickness direction, the first surface 111 is configured to be close to one side of the display device 100, and the second surface 112 is configured to be close to one side of the wall 300.

[0129] It can be understood that the thickness direction of the bracket body 11 is the front-rear direction of the display device 100, the first surface 111 is the side close to the user, and the second surface 112 is the side away from the user.

[0130] In some embodiments, in combination with Figure 8 and Figure 9The second surface 112 is provided with a groove 112a, and the limiting member 13 is arranged in the groove 112a. An outer surface 132 of the limiting member 13 is lower than the second surface 112 or flush with the second surface 112.

[0131] By forming the groove 112a on the second surface 112 of the frame body 11 close to the wall 300 for arranging the limiting member 13, the limiting member 13 can be arranged in the thickness space of the frame body 11, and the thickness space of the limiting member 13 and the thickness space of the frame body 11 are multiplexed. In addition, the structure is simple and easy to implement.

[0132] Optionally, the limiting member 13 can be connected to the groove 112a of the frame body 11 by riveting, screwing or the like. In this way, when the limiting member 13 is damaged and the limiting effect on the hanging ring 22 is lost, only the damaged limiting member 13 needs to be replaced, without the need to replace the entire first bracket 10, thereby facilitating maintenance and saving costs.

[0133] It should be noted that the outer surface 132 of the limiting member 13 can refer to a surface of the limiting member 13 close to the wall 300 along the second direction Y (the thickness direction of the frame body 11, i.e., the front-to-back direction of the wall-mounted structure 200) when the first bracket 10 is connected to the wall 300 and in use. The outer surface 132 of the limiting member 13 is lower than the second surface 112 or flush with the second surface 112, i.e., the part of the limiting member 13 connected to the groove 112a is completely accommodated in the groove 112a, without protruding from the second surface 112 of the frame body 11.

[0134] In some embodiments, the hook 12 includes a first section 121 protruding from the first surface 111. It can be understood that the first section 121 can serve as the part that mainly bears the hanging ring 22 after the hanging ring 22 is hung on the hook 12.

[0135] In some embodiments, the hook 12 includes a second section 122 connected to the first section 121. The second section 122 extends upward along the first direction Z to form a space with the first section 121 for the hanging ring 22 to be hung on. The second section 122 is configured to limit the position of the hanging ring 22 in the second direction Y.

[0136] It can be understood that the cross section of the hook 12 can be L-shaped. The L-shaped hook 12 is simple in structure and convenient to process. The L-shaped hook 12 can be integrally formed with the frame body 11, i.e., the frame body 11 is a sheet metal part. The first section 121 is formed by first bending the top end 11a of the frame body 11 along the second direction Y and towards the side of the display device 100, and the second section 122 is formed by second bending the top end 11a of the frame body 11 along the first direction Z and upwards. In this way, the L-shaped hook 12 can be conveniently hung and connected with the hanging ring 22.

[0137] Of course, in other embodiments, the hook 12 can also be a curved hook 12, that is, the first section 121 is curved, and the second section 122 extends upward in the first direction Z. Alternatively, the hook 12 can also be approximately in the shape of a "√", that is, the second section 122 and the first section 121 form an acute angle, as long as it can be more conveniently hung with the ring 22 and is more convenient to process and form.

[0138] In some embodiments, the size of the first section 121 in the second direction Y is less than or equal to the size of the ring 22 in the second direction Y.

[0139] By dividing the hook 12 into the first section 121 protruding from the first surface 111 and the second section 122 extending in the first direction Z, and limiting the size of the first section 121 in the second direction Y to be less than or equal to the size of the ring 22 in the second direction Y, when the size of the first section 121 in the second direction Y (the thickness direction of the frame part 11) is equal to the size of the ring 22 in the second direction Y, the ring 22 can be just hung on the first section 121, so that the overall thickness of the wall hanging structure 200 is the sum of the thickness of the frame part 11, the size of the ring 22 and the size of the second section 122, at this time the maximum thickness of the wall hanging structure 200 can be achieved; when the size of the first section 121 in the second direction Y is less than the size of the ring 22 in the second direction Y, in the hung state, the ring 22 will be hung on the frame part 11 in addition to the first section 121, so that the overall thickness of the wall hanging structure 200 is the partial thickness of the frame part 11, the size of the ring 22 and the size of the second section 122, at this time the overall thickness of the wall hanging structure 200 can be further reduced, which is more conducive to the thinning effect of the wall hanging structure 200.

[0140] Of course, in some embodiments, if the first section 121 coincides with the frame part 11 in the second direction Y, the ring 22 is directly hung in the thickness space of the frame part 11.

[0141] Referring to Figure 11 and Figure 12 , the size of the frame part 11 in the second direction Y is T1, and the size of the second section 122 in the second direction Y is T2, T2≤T1.

[0142] Since the size of the frame part 11 and the second section 122 in the second direction Y constitutes two parts of the overall thickness of the wall hanging structure 200, and the second section 122 provides a hanging space for the ring 22 and limits the position of the ring 22 in the second direction Y, by limiting the size of the second section 122 in the second direction Y to be less than or equal to the size of the frame part 11 in the second direction Y, the relationship is satisfied, and under the premise of being able to meet the structural strength, the size of the second section 122 is made smaller, which is more conducive to the thickness reduction of the wall hanging structure 200.

[0143] In some embodiments, the size T1 of the frame body 11 in the second direction Y is ≥1.2 mm. Optionally, the size of the frame body 11 in the second direction Y can be 1.2 mm, 1.3 mm, or 1.5 mm, etc.

[0144] In some embodiments, the size T2 of the second section 122 in the second direction Y is ≥1.2 mm. Optionally, the size of the second section 122 in the second direction Y can be 1.2 mm, 1.3 mm, or 1.5 mm, etc.

[0145] In some embodiments, the size T3 of the hanging ring 22 in the second direction Y is ≥4 mm. Optionally, the size of the hanging ring 22 in the second direction Y can be 4 mm, 4.2 mm, or 4.5 mm, etc.

[0146] By satisfying the above relationship, the size of each component of the wall-mounted structure 200 in the second direction Y can be made small enough, so that the overall thickness of the wall-mounted structure 200 can be made to be the thinnest 6.4 mm, and the structural strength of each component can be effectively guaranteed. If the above parameters are too small, the structural strength of each component cannot be guaranteed, which affects the overall mechanical properties of the wall-mounted structure 200.

[0147] The wall-mounted display device disclosed in the embodiments of the present application is described in detail above, and specific examples are applied in this paper to describe the principles and implementation modes of the present application. The above embodiment description is only used to help understand the wall-mounted display device and its core idea of the present application; at the same time, for those skilled in the art, according to the idea of the present application, the specific implementation mode and application range will be changed; in summary, the content of the specification should not be understood as a limitation of the present application.
