In order to make the technical scheme of the utility model more clear and specific to those skilled in the art, the implementation methods described below are not limited to this. The utility model is further described in detail below in combination with the embodiments and the accompanying drawings.

[0046] In the present invention, the terms "first", "second", and "third" are used for descriptive purposes only and should not be understood as indicating or implying relative importance; the term "plurality" refers to two or more, unless otherwise clearly defined. The terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense.

[0047] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by terms such as "up", "down", "left", "right", "front" and "back" are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or unit referred to must have a specific direction, be constructed and operated in a specific orientation, and therefore, cannot be understood as a limitation on the present invention.

[0048] The first aspect of the utility model is as follows Figure 1-Figure 11 , a display device is provided, including a display screen assembly 100, a control box 2 is provided on the non-display surface of the display screen assembly 100, and at least a portion of the control box 2 can be moved outside the edge projection area of ​​the display screen assembly 100; the display device includes a wire 24, at least a portion of the wire 24 is located in the control box 2, a first end of the wire 24 is connected to the display screen assembly 100, and a second end of the wire 24 is connected to a movable part of the control box 2, and the wire 24 includes a bending portion 243, and the wire 24 can be bent at the bending portion 243 so that the wire 24 is deformed as the control box 2 moves.

[0049] like Figure 2-Figure 5 As shown, the display device provided by the present invention realizes front maintenance by arranging a movable control box 2 on the back of the display screen assembly 100, such as Figure 6 As shown, at least a portion of the control box 2 can be moved outside the edge projection area of ​​the display screen assembly 100, so that the control module 27 in the control box 2 is exposed, which is convenient for maintenance and debugging from the front of the display screen assembly 100. There is no need to disassemble the display screen assembly 100, which greatly reduces the difficulty and time of maintenance, saves time and effort, and improves maintenance efficiency.

[0050] like Figure 3-Figure 5 As shown, the wire 24 in the control box 2 has a margin for the moving distance of the control box 2. As the control box 2 moves, the wire 24 can be bent and deformed, and the two ends of the wire 24 are always connected to the control box 2 and the display screen assembly 100 respectively. During the movement of the control box 2, the wire 24 is always located in the control box 2, and the movement of the control box 2 will not pull the wire 24. The connection between the wire 24 and the display screen assembly 100 and the control box 2 is stable, and the structure and position of the wire 24 itself are stable, which is convenient for front maintenance of the wire 24 in the control box 2, and there is no need to disassemble the display screen assembly 100, thereby improving maintenance efficiency.

[0051] In one possible implementation, Figure 3-Figure 6 As shown, the control box 2 includes a first half shell 21 and a second half shell 22. The first half shell 21 is fixed relative to the display screen assembly 100. The first half shell 21 and the second half shell 22 are movably connected. The second half shell 22 can move toward or away from the display screen assembly 100. A control module 27 is arranged in the second half shell 22.

[0052] The first half shell 21 and the display screen assembly 100 are relatively fixed in position, and the first half shell 21 can be fixedly installed or detachably installed on the non-display surface of the display screen assembly 100 , that is, the back side of the display screen assembly 100 .

[0053] Among them, the second half shell 22 can move relative to the first half shell 21, and the moving direction can be along at least one of the horizontal direction, vertical direction, oblique direction, and rotation angle, so that at least part of the second half shell 22 can be moved outside the edge area of ​​the display screen assembly 100, so that the control module 27 in the second half shell 22 is exposed, thereby realizing front maintenance of the control module 27.

[0054] When the second half shell 22 moves in a straight line relative to the first half shell 21, the second half shell 22 can slide relative to the first half shell 21, and the second half shell 22 slides in a direction away from the first half shell 21, so that at least a portion of the second half shell 22 is located outside the outer edge of the display screen assembly 100, so that the control module 27 is located outside the outer edge of the display screen assembly 100.

[0055] When the second half shell 22 rotates relative to the first half shell 21, the two can be rotationally connected through the shaft 203, and can also be rotationally connected through an arc-shaped slide rail, or through other connection methods that can achieve rotation. The shaft 203 can be set at a position of the control box 2 close to the outer edge of the display screen assembly 100, so that after the second half shell 22 rotates with the shaft 203 as the rotation center, at least a portion of the second half shell 22 is located outside the outer edge of the display screen assembly 100, so that the control module 27 is located outside the outer edge of the display screen assembly 100.

[0056] Among them, the first half shell 21 and the second half shell 22 enclose to form a accommodating cavity for accommodating the control module 27 and part of the wire 24. The first half shell 21 is arranged on the back of the display screen assembly 100. The first half shell 21 includes at least one side panel. When the second half shell 22 moves away from the display screen assembly 100, the second half shell 22 is separated from the side panel; the second half shell 22 includes at least one side panel. When the second half shell 22 moves away from the display screen assembly 100, the side panel is separated from the first half shell 21; the two side panels are respectively located on both sides of the control box 2 and do not interfere with the movement of the second half shell 22. The control box 2 also includes a main board, a top plate and a bottom plate, the top plate and the bottom plate are arranged at the upper and lower ends of the main board, and at least one of the main board, the top plate and the bottom plate is arranged on the second half shell 22; the number of main boards can be two, that is, two main boards, the top plate, the bottom plate and the two side plates are enclosed to form a relatively closed accommodating cavity, at this time, the first half shell 21 includes a main board and is located on the back side close to the display screen assembly 100, and the second half shell 22 includes a main board and is located on the side away from the display screen assembly 100; when the number of main boards is one, the main board is located at the end of the control box 2 away from the display screen assembly 100, and the non-display surface of the display screen assembly 100 achieves the function of a main board, that is, the non-display surface of the display screen assembly 100, a main board, the top plate, the bottom plate and the two side plates are enclosed to form a relatively closed accommodating cavity.

[0057] In this embodiment, the control box 2 is a square shape as an example, and the control box 2 can also be a circular, polygonal, elliptical, or irregular shape.

[0058] Among them, Figure 3 As shown, the display device further includes a slide rail assembly 23 , which is disposed between the first half shell 21 and the second half shell 22 . The first half shell 21 and the second half shell 22 are slidably connected via the slide rail assembly 23 .

[0059] It can be understood that the slide rail assembly 23 includes a slideway and a slider. The slideway can be set on the first half shell 21, and the slider is set on the second half shell 22. The slider slides on the slideway to achieve the sliding of the second half shell 22 relative to the first half shell 21.

[0060] It is understandable that the slideway may also be provided on the second half shell 22 , and the slider may be provided on the first half shell 21 , and the second half shell 22 may slide relative to the first half shell 21 by sliding the slider on the slideway.

[0061] The slide rail assembly 23 may be of a self-locking type, and the slide rail assembly 23 further includes a self-locking member. When the second half shell 22 slides to a position covering the first half shell 21 , the positions of the two can be stabilized by the self-locking member.

[0062] Among them, Figure 8 As shown, a fixing member 4 can also be provided on the back of the display screen assembly 100, through which the slide rail assembly 23 or the first half shell 21 is fixed to the display screen assembly 100, and the fixing can be a connecting piece, a bolt, a buckle or other structure.

[0063] In one possible implementation, Figure 4 and Figure 5 As shown, the display device further includes a connecting member 25 , a first end of the connecting member 25 is connected to the first half shell 21 or the display screen assembly 100 , and a second end of the connecting member 25 is connected to the wire 24 .

[0064] Among them, the relative fixation of the wire 24 and the first half shell 21 is achieved through the connecting member 25. The connecting member 25 can fix a point of the wire 24 on the first half shell 21 or the non-display surface of the display screen assembly 100, thereby improving the stability of the position of the wire 24 during the movement of the second half shell 22 relative to the first half shell 21.

[0065] The connecting member 25 may be a wire buckle, a wire loop, an adhesive or other structure, which can fix a point of the wire 24 on the first half shell 21 or the non-display surface of the display screen assembly 100 .

[0066] In this embodiment, the connecting member 25 is taken as a wire loop as an example, that is, the connecting member 25 is an annular coil, one end of the annular coil is fixed on the first half shell 21 or the display screen assembly 100, and the wire 24 passes through the inner cavity of the annular coil. The inner diameter of the inner cavity is larger than the outer diameter of the wire 24, which can initially fix the wire 24 while not affecting the pulling movement of the wire 24.

[0067] Among them, Figure 4 and Figure 5 As shown, the wire 24 on one side of the connecting member 25 forms a first line segment 241 connected to the display screen assembly 100 , and the wire 24 on the other side of the connecting member 25 forms a bending portion 243 and a second line segment 242 connected to the second half shell 22 .

[0068] The connecting member 25 separates the wire 24 into two segments. The first segment 241 is located between the connecting member 25 and the display assembly 100, and the second segment 242 is located between the connecting member 25 and the second half shell 22. A bending portion 243 is formed between the first segment 241 and the second segment 242, and the bending portion 243 is located between the connecting member 25 and the second half shell 22.

[0069] Among them, Figure 4 and Figure 5 As shown, during the movement of the second half shell 22 , the second half shell 22 drives the bending portion 243 and the second line segment 242 to deform.

[0070] During the movement of the second half shell 22 , the first line segment 241 remains substantially stationary, and the second line segment 242 deforms as the second half shell 22 moves. When the second line segment 242 deforms, the bending portion 243 is driven to bend to adapt to the deformation of the second line segment 242 .

[0071] The wire 24 is made of a bendable non-rigid material.

[0072] In which, along the direction perpendicular to the movement of the second half shell 22, the connection end of the wire 24 and the display screen assembly 100 and the connection end of the wire 24 and the second half shell 22 can be located on the same side of the bending portion 243, and the first line segment 241 is formed on the side facing the second half shell 22 with an area for the second line segment 242 and the bending portion 243 to deform. When the control box 2 is closed, Figure 5 As shown, the wires 24 in the control box 2 are approximately Z-shaped, which reduces the space occupied by the wires 24 .

[0073] In which, along the moving direction perpendicular to the second half shell 22 , the connection ends of the wire 24 and the display screen assembly 100 and the connection ends of the wire 24 and the second half shell 22 can be located on both sides of the bending portion 243 , and the first line segment 241 and the second line segment 242 have no interference.

[0074] In order to achieve complete front maintenance, the connection end of the wire 24 and the display screen assembly 100 is not located on the back of the display screen assembly 100, but can be located at the outer edge of the display screen assembly 100, that is, the top, bottom and both sides; the connection end of the wire 24 and the second half shell 22 is located at a position where the second half shell 22 can move to expose the outer edge of the display screen assembly 100.

[0075] In one possible implementation, Figure 2-Figure 6 As shown, the second half shell 22 has a first position and a second position. When the second half shell 22 moves toward the first half shell 21 to the first position, the second half shell 22 covers the first half shell 21; when the second half shell 22 moves toward the second position away from the first half shell 21, at least part of the second half shell 22 is located outside the edge projection area of ​​the display screen assembly 100, so that the control module 27 in the control box 2 is exposed.

[0076] When the second half shell 22 is located at the first position, the second half shell 22 covers the first half shell 21 to form a relatively closed accommodating cavity; when the second half shell 22 is located at the second position, at least a portion of the control module 27 in the first half shell 21 is located outside the outer edge of the display screen assembly 100.

[0077] In one possible implementation, Figure 1 , Figure 4 , Figure 9-11 As shown, the display device also includes a frame assembly 200, which is arranged at the outer edge of the display screen assembly 100. The frame assembly 200 includes a frame body 202 and a cover plate 201. The frame body 202 is provided with a wire hole 26 for the wire 24 to pass through, and the cover plate 201 can move relative to the frame body 202 to expose the inner cavity of the frame body 202.

[0078] Among them, the frame assembly 200 can be set at the outer edge of the display screen assembly 100, that is, the top, bottom, left or right side of the display screen assembly 100; the frame assembly 200 includes a frame 202 and a cover plate 201, the frame 202 is connected to the display screen assembly 100, the cover plate 201 is movably connected to the frame 202, and a wire hole 26 is opened on the frame 202, and the wire 24 passes through the wire hole 26 to be connected to the display screen assembly 100, that is, a part of the wire 24 is located in the inner cavity of the frame 202, and the other part is located in the control box 2, and the inner cavity of the frame 202 can be exposed by moving the cover plate 201, and the inner cavity of the frame 202 is opened to face the front, which is convenient for front maintenance.

[0079] Among them, Fig.10 and Fig.11As shown, the cover plate 201 includes a fixed end and a free end. The fixed end is rotatably connected to the frame 202 via a rotating shaft 203 , and the free end is movably connected to the frame 202 via a magnetic attraction member 204 .

[0080] It can be understood that the frame 202 has an inner cavity and an opening, and the cover 201 is used to cover the opening. The cover 201 and the frame 202 can be rotatably connected. In this embodiment, the top of the cover 201 is rotatably connected to the frame 202 through the rotating shaft 203 as an example. The moving direction of the cover 201 is as follows: Fig.11 As shown by the arrow, the movable connection is achieved by providing corresponding magnetic suction parts 204 at the bottom of the cover plate 201 and the frame body 202.

[0081] The magnetic attraction member 204 includes a magnet and an iron sheet, which are respectively arranged at corresponding positions of the cover plate 201 and the frame body 202, and are connected and separated by magnetic attraction between the magnet and the iron sheet.

[0082] Among them, since the wire 24 passes through the annular coil, the wire 24 can be tied with a thin wire in a similar way to the maintenance of electric wires. The wire 24 is first pulled out, and then the newly replaced wire 24 is put on the thin wire and passed through the annular coil, thereby achieving complete front maintenance of the wire 24 between the frame 202 and the cover 201.

[0083] In one possible implementation, Figure 1-Figure 8 As shown, the display screen assembly 100 includes at least two box assemblies 1 arranged in a row along a first direction, and the multiple box assemblies 1 are detachably connected; the box assembly 1 includes at least two box bodies 11 and display modules 12 arranged in a row along a second direction, and the first direction is different from the second direction.

[0084] The common spliced ​​display screens on the market are installed by splicing multiple boxes one by one, which results in a long installation and debugging time, time-consuming and labor-intensive, and affects the user experience. This embodiment provides a box assembly 1 composed of multiple boxes arranged in rows, which can be assembled in advance during production to ensure the assembly accuracy of the box assembly 1. After that, the multiple box assemblies 1 are transported to the site of use. On site, only the multiple rows of box assemblies 1 need to be spliced, which greatly reduces the time spent on splicing at the site of use, ensures the flatness of the large screen, improves assembly accuracy and assembly efficiency, and improves user satisfaction.

[0085] Among them, multiple box bodies 11 of a box assembly 1 are fixedly connected, and the multiple box bodies 11 can be an integrated structure. They are assembled through magnetic connection between the box body 11 and the display module 12. A row of long boxes is used in the production process, which can be quickly spliced ​​at the site of use and can be fully maintained in front.

[0086] Among them, multiple box bodies 11 can be arranged in rows or in columns; multiple box components 1 can be arranged in rows or in columns, depending on the shape of the large display screen and assembly requirements.

[0087] Among them, Figure 8 and Fig. 9 As shown, if the display device is wall-mounted, a hanging piece 3 may be provided on the box assembly 1, and the hanging piece 3 is connected to the mounting seat 301 on the carrier 300.

[0088] Specifically, the hanging piece 3 is arranged at the top position of the box assembly 1, and the position and structure of the hanging piece 3 and the mounting seat 301 are adapted. The two ends of the hanging piece 3 are connected to the back of the box assembly 1. The middle of the hanging piece 3 is located with a gap between the box assembly 1, and the mounting seat 301 is connected to the carrier 300. The mounting seat 301 has a raised structure, which is inserted into the gap position between the hanging piece 3 and the box assembly 1 to realize the connection between the two, so that the large display screen can be suspended in the air.

[0089] In one possible implementation, the first direction and the second direction are arranged at 90°.

[0090] It can be understood that for a large display screen of a standard shape, the box body 11 is a square, the box assembly 1 is a long square, and a plurality of box assemblies 1 are spliced ​​to form a large square display screen, in which case the first direction and the second direction are 90°.

[0091] It is understandable that, depending on the shape and assembly method of the large display screen, for example, the overall structure of the large display screen is fan-shaped, multi-deformed, or irregular, the angle between the first direction and the second direction may also be other angles to meet different needs.

[0092] The second aspect of the utility model is as follows Figure 1-Figure 11 As shown, a display system is provided, comprising a display device as described in any one of the first aspects.

[0093] In the description of this specification, the description of the terms "one embodiment", "some embodiments", "specific embodiments", etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0094] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.

[0095] In view of the above detailed description, these and other changes can be made to these embodiments, and this written description includes the best mode embodiments to disclose the utility model.
