Description

Technical Field

[0001] This invention relates to the field of display technology, and more particularly to a display device. Background Technology

[0002] Display devices are widely used in production and daily life, and are typically used to provide users with image information such as images and text.

[0003] The display device includes a display unit and a support unit. The display unit is equipped with a magnetic component that is movably connected. In this way, the display device can be fixed to the support unit by the magnetic force between the magnetic component and the support unit, which makes disassembly and assembly convenient and facilitates the splicing of multiple display units.

[0004] However, the magnetic force between the magnetic components and the support unit is relatively large during assembly and disassembly, which can easily cause collision damage to the display unit. Summary of the Invention

[0005] This application provides a display device. The display device provided by this application can prevent collision damage to the display unit during disassembly and assembly.

[0006] The device provided in this application includes a display unit, a support unit, and an adjustment unit. The adjustment unit includes a first connector, a second connector, a rolling element, and an adjusting element. The first connector is detachably connected to the display unit, and the second connector is detachably connected to the support unit. The first connector has a wedge-shaped cavity, and the second connector has a plug-in portion extending into the wedge-shaped cavity, with the plug-in portion extending along the length direction of the wedge-shaped cavity. The adjusting element is located at the large end of the wedge-shaped cavity, and the rolling element is located within the wedge-shaped cavity. One of the first connector and the second connector is slidably connected to the adjusting element, and the adjusting element abuts against the side of the rolling element facing the large end of the wedge-shaped cavity. The plug-in portion and the cavity wall of the wedge-shaped cavity jointly press against the rolling element, and the plug-in portion is relatively fixed to the first connector by the friction of the rolling element.

[0007] In one possible implementation, the rolling element abuts against the side of the insertion portion, and there is an angle between the side wall of the insertion portion and the cavity wall of the wedge-shaped cavity.

[0008] In one possible implementation, the larger end of the wedge-shaped cavity faces one side of the display unit.

[0009] In one possible implementation, the wedge cavity is a rotary cavity; the outer diameter of the rolling element is smaller than the radius of the large end of the wedge cavity and larger than the radius of the small end of the wedge cavity.

[0010] In one possible implementation, the first connector and the second connector are slidably connected in a direction perpendicular to the display surface of the display unit, and the adjusting member is slidably connected to the first connector in a direction perpendicular to the display surface of the display unit.

[0011] In one possible implementation, the first connector is provided with a groove that extends in a direction perpendicular to the display surface of the display unit, and the plug-in portion extends into the groove and is movable relative to the groove.

[0012] In one possible implementation, the first connector is further provided with a retaining portion, which surrounds the outer side of the insertion portion in the circumferential direction, and a portion of the sidewall of the retaining portion forms the cavity wall of the wedge-shaped cavity.

[0013] In one possible implementation, the adjusting member has a grippable operating part and a push part connected to the operating part, the push part being located inside the enclosure part and opposite to the large end of the wedge-shaped cavity, and the operating part extending to the circumferential outer side of the enclosure part.

[0014] As an optional implementation, the display device further includes a first elastic element, which connects the first connector and the second connector, wherein the direction of the elastic force of the first elastic element is parallel to the relative sliding direction of the first connector and the second connector; and / or, the display device further includes a second elastic element, which connects the adjusting member and the first connector, wherein the direction of the elastic force of the second elastic element is toward the rolling member.

[0015] As an optional implementation, the second connector includes a fixing part and a connecting part, the fixing part being detachably connected to the support unit, the connecting part being slidably connected to the first connector, and the fixing part and the connecting part being detachably connected.

[0016] This application provides a display device. The display device provided by this application includes a display unit, a support unit, and an adjustment unit, wherein the adjustment unit is used to connect the display unit and the support unit. When the rolling element is located at the small end of the wedge-shaped cavity, the rolling element can be sandwiched between a first connecting member and a second connecting member. At this time, the first connecting member, the rolling element, and the second connecting member are all relatively fixed, that is, the display unit is mounted on the support unit through the adjustment unit.

[0017] Since the first connector and the display unit are detachably connected, and the second connector and the support unit are detachably connected, the display unit can be assembled or disassembled relative to the support unit by connecting or disconnecting the first connector and the display unit, or by connecting or disconnecting the second connector and the support unit.

[0018] Simultaneously, when the first and second connecting members move relative to each other, they can cause the rolling element to roll relative to the cavity wall of the wedge-shaped cavity. Therefore, when assembling or disassembling the display device, the rolling element can first be moved to the large end of the wedge-shaped cavity by adjusting the component and moving relative to the first and second connecting members. At this time, the first and second connecting members are in a state of relative movement, that is, the display unit and the support unit are in a flexible connection state. Therefore, when the connection between the adjusting units or between the adjusting unit and the support unit is disconnected, a rigid collision of the display device will not occur, resulting in a high level of safety for the display device.

[0019] In addition to the technical problems solved by the embodiments of this application, the technical features constituting the technical solutions, and the beneficial effects brought about by the technical features of these technical solutions described above, other technical problems that the display device provided by this application can solve, other technical features included in the technical solutions, and the beneficial effects brought about by these technical features will be further described in detail in the specific embodiments.

[0038] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this application, but not all embodiments.

[0039] First, those skilled in the art should understand that these embodiments are merely for explaining the technical principles of this application and are not intended to limit the scope of protection of this application. Those skilled in the art can make adjustments as needed to adapt to specific application scenarios.

[0040] Secondly, it should be noted that in the description of this application, the terms "inner" and "outer," etc., which indicate the direction or positional relationship, are based on the direction or positional relationship shown in the accompanying drawings. This is only for the convenience of description and does not indicate or imply that the device or component must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this application.

[0041] Furthermore, it should be noted that, in the description of this application, unless otherwise expressly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0042] It should be noted that, in this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature. The terms "above," "below," etc., are used to describe the relative positional relationship of the various structures in the accompanying drawings, solely for clarity of description, and are not intended to limit the scope of the invention. Changes or adjustments to these relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention.

[0043] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this disclosure. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0044] In existing technology, magnetic components are connected to both the display unit and the support unit, and the display unit is mounted on the support unit by the attraction between the two magnetic components. Understandably, the magnetic force between the two magnetic components is relatively strong at the moment of attraction or separation, making it difficult for assemblers to control the relative position between the two magnetic components at these moments. This can lead to the display unit easily colliding rigidly with the support unit or other components, resulting in damage to internal components such as LED beads falling out, thus reducing the safety of the display unit.

[0045] Furthermore, when installing the display unit, its installation height needs to be adjusted. For example, when multiple display units are spliced ​​together, adjusting the installation height of each display unit can prevent step differences between adjacent display units. In the prior art, adjusting the installation height of the display unit requires removing the display unit from the support unit, adjusting the installation height of the magnetic components between the display unit and the support unit, and then reinstalling the display unit on the support unit. This operation is inconvenient and has low assembly efficiency.

[0046] In view of the above problems, this application provides a display device, which includes a display unit, a support unit, and an adjustment unit. The adjustment unit is used to detachably connect the display unit and the support unit. The support unit has a locked state and an adjustable state. When the support unit is in the locked state, the display unit can be fixed on the support unit. When the support unit is in the adjustable state, the display unit and the support unit are in a flexible connection state that allows them to move relatively. In this way, when the display unit is assembled or disassembled, the adjustment state of the adjustment unit can be used for buffering to avoid rigid collisions between the display unit and other components, thus improving the safety of the display unit.

[0047] Meanwhile, depending on the different fixed positions of the first connector and the second connector, the adjustment unit can have different lengths. In this way, the installation height of the display unit relative to the support unit can be adjusted by changing the length of the adjustment unit during the installation of the display unit, which is convenient to operate and has high assembly efficiency.

[0048] The technical solution of the present invention and how the technical solution of the present invention solves the above-mentioned technical problems are described in detail below with specific embodiments. It should be noted that the following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of the present invention will be described below with reference to the accompanying drawings.

[0049] Please see Figures 1 to 5 This embodiment provides a display device 10, which includes a display unit 100, a support unit 200, and an adjustment unit 300. The display unit 100 can be a television, an LED display, or the like. The support unit 200 can be a wall mount, a tabletop stand, or a wall, providing high stability. The adjustment unit 300 is used to connect the display unit 100 to the support unit 200.

[0050] In some embodiments, the adjustment unit 300 includes a first connector 310 and a second connector 320, wherein the first connector 310 is detachably connected to the display unit 100, and the second connector 320 is detachably connected to the support unit 200. The first connector 310 may be a metal part, a plastic part, etc., and the second connector 320 may be a metal part, a plastic part, etc. For example, both the first connector 310 and the second connector 320 are metal parts, which have high strength and a long service life.

[0051] In some embodiments, for ease of assembly and disassembly, the first connector 310 can be detachably connected to the display unit 100, for example, by screwing or snapping, and the second connector 320 can be detachably connected to the support unit 200, for example, by screwing or snapping. In this way, the adjustment unit 300 can be installed on either the display unit 100 or the support unit 200, and the assembly and disassembly of the display unit 100 can be achieved by connecting or disconnecting the adjustment unit 300 from the other. This embodiment uses the example of the adjustment unit 300 being installed on the display unit 100 for illustration.

[0052] The adjustment unit 300 further includes a rolling element 330 and an adjusting element 340. The rolling element 330 can be a rolling ball, a rolling column, etc. This embodiment uses a rolling ball as an example for explanation. The number of rolling elements 330 can be multiple. The first connecting member 310 has a wedge-shaped cavity, and the second connecting member 320 has an insertion part 321 that extends into the wedge-shaped cavity. The insertion part 321 extends along the length direction of the wedge-shaped cavity. The adjusting element 340 is located at the large end of the wedge-shaped cavity, and the rolling element 330 is located inside the wedge-shaped cavity. That is, the rolling element 330 is located within the wedge-shaped region M formed by the cavity wall of the wedge-shaped cavity, the side wall of the insertion part 321, and the adjusting element 340. The width of the wedge-shaped cavity gradually decreases from the end closer to the adjusting element 340 to the end farther away from the adjusting element 340. The adjusting element 340 can act as a limiting member to limit the rolling element 330 within the wedge-shaped region M to prevent the rolling element 330 from rolling out.

[0053] Therefore, when the rolling element 330 is located at different positions in the wedge cavity, that is, at different positions in the wedge region M, the first connecting element 310 and the second connecting element 320 can have different connection states.

[0054] When the rolling element 330 is located at the small end of the wedge cavity, that is, when the rolling element 330 is located at the small end of the wedge region M, the adjusting element abuts against the side of the rolling element 330 facing the large end of the wedge cavity; the insertion part 321 and the cavity wall of the wedge cavity jointly squeeze the rolling element 330, and the insertion part 321 is relatively fixed to the first connecting member 310 by the friction of the rolling element 330. At this time, the adjusting unit is in a locked state, the first connecting member 310 and the second connecting member 320 are relatively fixed by the rolling element 330, and the display unit 100 and the adjusting unit 300 are relatively fixed.

[0055] When the adjusting member 340 moves to the large end of the wedge cavity and the rolling member 330 is located at the large end of the wedge cavity, that is, when the rolling member 330 is located at the large end of the wedge region M, the rolling member 330 can roll within the wedge region M. The first connecting member 310 and the second connecting member 320 are in a flexible connection state that can move relatively. That is, at this time, the display unit 100 and the adjusting unit 300 are in a flexible connection state that can move relatively.

[0056] Understandably, when the first connecting member 310 and the second connecting member 320 move relative to each other, the width of the wedge-shaped region M at the location of the rolling member 330 can change. That is, when the first connecting member 310 and the second connecting member 320 move relative to each other, the cavity wall of the wedge-shaped cavity and the side wall of the insertion part 321 can drive the rolling member 330 to roll, thereby changing the width of the wedge-shaped region M at the location of the rolling member 330. Specifically, depending on the different relative movement directions of the first connecting member 310 and the second connecting member 320, the rolling member 330 can be driven to move towards the large end of the wedge-shaped cavity, or it can be driven to move towards the small end of the wedge-shaped cavity.

[0057] The adjusting member 340 is slidably connected to one of the first connecting member 310 and the second connecting member 320. Thus, when the adjusting member 340 moves toward the small end of the wedge-shaped cavity, it can push the rolling member 330 to move toward the small end of the wedge-shaped cavity. When the adjusting member 340 moves toward the large end of the wedge-shaped cavity, the adjusting member 340 no longer limits the rolling member 330 and provides rolling space for the rolling member 330.

[0058] Therefore, when assembling or disassembling the display unit 100, the state between the display unit 100 and the support unit 200 can switch between a fixed connection state, a flexible connection state, and a disconnected state. By setting a transitional flexible connection state, collision damage to the display unit 100 due to rigid impact can be avoided during assembly or disassembly, thus ensuring a high level of safety for the display unit 100.

[0059] Specifically, when installing the display unit 100, the initial state between the display unit 100 and the support unit 200 is disconnected. Then, the position of the adjusting member 340 can be maintained at the large end of the wedge-shaped cavity, and the second connecting member 320 is then connected to the support unit 200. Since the first connecting member 310 and the second connecting member 320 can still move relative to each other, the display unit 100 and the support unit 200 can move relative to each other, resulting in a flexible connection between the display unit 100 and the support unit 200. When the second connecting member 320 is connected to the support unit 200, the relative movement between the second connecting member 320 and the first connecting member 310 can provide buffering, preventing rigid collisions between the display unit 100 and the support unit 200 or between the display unit 100 and other components. Then, the adjusting member 340 can be moved towards the small end of the wedge cavity to push the rolling member 330. At the same time, the relative movement between the first connecting member 310 and the second connecting member 320 is coordinated so that the rolling member 330 is sandwiched between the first connecting member 310 and the second connecting member 320, and the display unit 100 and the support unit 200 are in a fixed connection state.

[0060] When disassembling the display unit 100, the initial state between the display unit 100 and the support unit 200 is a fixed connection. At this time, the adjusting member 340 can be moved first, and the relative position between the first connecting member 310 and the second connecting member 320 can be adjusted simultaneously to make the adjusting member 340 a flexible connection, that is, the display unit 100 and the support unit 200 are in a flexible connection state. At this time, the connection between the second connecting member 320 and the support unit 200 can be disconnected, and the relative movement between the second connecting member 320 and the first connecting member 310 can be used for buffering, avoiding rigid collisions between the display unit 100 and the support unit 200 or between the display unit 100 and other components when disassembling the display unit 100.

[0061] Understandably, in this embodiment, when the first connecting member 310 and the second connecting member 320 are relatively fixed by the rolling member 330, the first connecting member 310 and the second connecting member 320 may have different relative positions in the relative movement direction. Correspondingly, the length of the adjusting unit 300 in the relative movement direction is different. That is to say, the adjusting unit 300 has an adjustable length in this relative movement direction. In this way, the installation height of the display unit 100 relative to the support unit 200 can be adjusted by changing the length of the adjusting unit 300 during the installation of the display unit 100, which is convenient to operate and has high assembly efficiency.

[0062] In one possible implementation, the rolling element 330 abuts against the side of the insertion portion 321, and there is an angle between the side wall of the insertion portion 321 and the cavity wall of the wedge-shaped cavity, that is, the width of the wedge-shaped region M is also gradually changing in its own extension direction.

[0063] The sidewalls of the wedge cavity can have different shapes. For example, the cavity wall of the wedge cavity can be an arc-shaped wall or a flat wall, and the sidewall of the insertion part 321 can be an arc-shaped wall or a flat wall. Depending on the shape of the cavity wall of the wedge cavity and the sidewall of the insertion part 321, the extension directions of the cavity wall of the wedge cavity and the sidewall of the insertion part 321 are different.

[0064] One of the cavity wall of the wedge-shaped cavity and the side wall of the insertion part 321 can extend along the relative movement direction of the first connector 310 and the second connector 320, while the other is inclined to form a wedge-shaped region M. The structure of the adjustment unit 300 is relatively simple.

[0065] The larger end of the wedge cavity can face different directions; for example, the larger end of the wedge cavity may face the support unit 200. In one possible implementation, the larger end of the wedge cavity may face the display unit 100. Thus, when the display unit 100 and the support unit 200 move toward each other, the rolling element 330 may move toward the larger end of the wedge region M; conversely, when the display unit 100 and the support unit 200 move toward each other, the rolling element 330 may move toward the smaller end of the wedge region M.

[0066] Thus, when the support unit 200 is in a fixed connection state, and when the display unit 100 is disassembled, the assembler can move the adjustment member 340 toward the side closer to the display unit 100, and at the same time drive the display unit 100 toward the side closer to the support unit 200, so that the adjustment unit 300 switches to the adjustment state.

[0067] When installing the display unit 100, after moving the first connector 310 to the preset position, the assembler can move the adjusting member 340 toward the side away from the display unit 100, and at the same time pull the display unit 100 toward the side away from the support unit 200, so that the rolling member 330 is clamped between the cavity wall of the wedge-shaped cavity and the side wall of the insertion part 321, and the adjusting unit 300 switches to the fixed connection state, making it easier to disassemble and assemble the display unit 100.

[0068] In some embodiments, the adjustment member 340 may also be a magnetic material. In this way, when disassembling the display unit 100, the assembler holds the magnet and places it at the position corresponding to the adjustment member 340 on the front side of the display unit 100, so that the adjustment member 340 can be moved by the magnetic force between the magnet and the adjustment member 340, which makes the operation more convenient.

[0069] In some embodiments, an elastic connector (not shown), such as a spring, may be provided between the adjusting member 340 and the rolling member 330. When disassembling the display unit 100, the assembler moves the adjusting member 340 toward the side closer to the display unit 100, simultaneously pushing the display unit 100 toward the side closer to the support unit 200. At this time, the rolling member 330 is subjected to frictional forces from the wedge-shaped cavity wall and the side wall of the insertion portion 321, as well as the elastic force of the elastic connector, causing the rolling member 330 to disengage from the small end of the wedge-shaped region M. When installing the display unit 100, the assembler moves the adjusting member 340 toward the side farther from the display unit 100, simultaneously pulling the display unit 100 toward the side farther from the support unit 200. At this time, the rolling member 330 is subjected to frictional forces from the wedge-shaped cavity wall and the side wall of the insertion portion 321, as well as the elastic force of the elastic connector, causing the rolling member 330 to move toward the small end of the wedge-shaped region M. By setting up a flexible connector, the adjustment unit 300 can quickly and effectively switch between the adjustment state and the locked state.

[0070] In this configuration, to fix the first connecting member 310 and the second connecting member 320 relative to each other via the rolling element 330, the outer diameter of the rolling element 330 can be smaller than the radius of the large end of the wedge cavity and larger than the radius of the small end of the wedge cavity. That is, the outer diameter of the rolling element 330 can be smaller than the width of the large end of the wedge region M and larger than the width of the small end of the wedge region M. Thus, when the rolling element 330 is located at the large end of the wedge cavity, it can roll within the wedge region M, and the first connecting member 310 and the second connecting member 320 are in a flexible connection state that allows relative movement, while the adjusting unit 300 is in an adjusting state. When the rolling element 330 rolls towards the small end of the wedge cavity, it can gradually clamp between the first connecting member 310 and the second connecting member 320 until the first connecting member 310 and the second connecting member 320 are relatively fixed by the rolling element 330. At this point, the adjusting unit 300 is in a locked state.

[0071] Depending on the shape of the insertion part 321, the shape of the wedge-shaped region M also varies. For example, when the insertion part 321 is a plate-like structure, the cavity wall of the wedge-shaped cavity and the side wall of the insertion part 321 can both be planar walls, with one side wall perpendicular to the plane where the display unit 100 is located and the other side wall inclined, so that there is an angle between the cavity wall of the wedge-shaped cavity and the side wall of the insertion part 321.

[0072] In some embodiments, the wedge cavity is a rotary cavity, and the cavity wall of the wedge cavity is an annular wall. In this case, the insertion part 321 can be an insertion post, and the wedge region M is also a rotary cavity. Multiple rolling elements 330 are spaced apart in the circumference of the insertion part 321, resulting in a more compact structure.

[0073] To facilitate adjustment of the installation height of the display unit 100 relative to the support unit 200, the relative moving direction of the first connector 310 and the second connector 320 may have an angle with the display surface of the display unit 100, such as an acute angle or an obtuse angle.

[0074] As one possible implementation, the first connector 310 and the second connector 320 can also be slidably connected along a direction perpendicular to the display surface of the display unit 100. That is, the relative movement direction of the first connector 310 and the second connector 320 is perpendicular to the display surface of the display unit 100, and the vertical direction of the display surface of the display unit 100 is parallel to the relative movement direction. The change in the length of the adjustment unit 300 in the vertical direction of the display surface of the display unit 100 is the change in the installation height of the display unit 100 relative to the support unit 200. In this way, the installation height of the display unit 100 relative to the support unit 200 can be adjusted within a large range.

[0075] Furthermore, when multiple display units 100 are spliced ​​together, the installation height of each display unit 100 can be easily adjusted to avoid step differences between adjacent display units 100.

[0076] The moving direction of the adjusting member 340 may form an angle with the vertical direction of the display surface of the display unit 100. As one possible implementation, the adjusting member 340 and the first connecting member 310 are slidably connected in a direction perpendicular to the display surface of the display unit 100. This allows the position of the adjusting member 340 to be changed vertically along the display surface of the display unit 100 when assembling or disassembling the display unit 100 or adjusting its installation height, making operation more convenient.

[0077] As one possible implementation, in order to realize the relative movement of the first connector 310 and the second connector 320, the first connector 310 is provided with a sliding groove 311. The sliding groove 311 extends in a direction perpendicular to the display surface of the display unit 100. The plug-in part 321 extends into the sliding groove 311 and can move relative to the sliding groove 311. In this way, when the plug-in part 321 moves relative to the sliding groove 311, the relative movement of the first connector 310 and the second connector 320 in the vertical direction of the display device 10 can be realized. The structure is relatively simple and the operation is convenient.

[0078] In some embodiments, the first connector 310 is further provided with a retaining portion 312, which surrounds the outer circumferential side of the insertion portion 321, and a portion of the sidewall of the retaining portion 312 forms the cavity wall of the wedge-shaped cavity. That is, the insertion portion 321 can extend into the wedge-shaped cavity surrounded by the retaining portion 312, and a plurality of rolling elements 330 are distributed circumferentially on the outer circumferential side of the insertion portion 321. In other words, this embodiment utilizes the sliding connection structure of the first connector 310 and the second connector 320 to form the wedge-shaped region M, and the structure of the adjustment unit 300 is relatively simple.

[0079] Furthermore, when the rolling element 330 is clamped at different positions along the length of the insertion part 321, the length of the insertion part 321 extending into the wedge cavity is different, and the adjustment unit 300 has different lengths.

[0080] In some embodiments, a limiting protrusion is provided on the outer wall surface of the insertion part 321 located at one end of the enclosure part 312 to prevent the insertion part 321 from disengaging from the slide groove 311 during the reciprocating movement of the insertion part 321.

[0081] The cavity wall of the wedge-shaped cavity is a conical wall surface surrounding the axis of the insertion part 321, and the generatrix of the conical wall surface can be an arc (not shown). In some embodiments, the generatrix of the conical wall surface can also be a straight line (e.g., Figure 3 As shown in the figure, the structure of the enclosure part 312 is relatively simple and easy to form.

[0082] As an optional implementation, to facilitate the movement of the adjusting member 340, the adjusting member 340 has an operating part 342 for gripping and a pushing part 341 connected to the operating part 342. The pushing part 341 is located inside the enclosure part 312 and is opposite to the large end of the wedge cavity. In this way, the pushing part 341 can serve as a limiting structure to prevent the rolling member 330 from rolling out of the wedge cavity. At the same time, the pushing part 341 can also push the rolling member 330 toward the small end of the wedge cavity.

[0083] Understandably, the push-up portion 341 is provided with a clearance structure to avoid the insertion portion 321. The clearance structure can be a through hole (not shown) penetrating the push-up portion 341, or it can be a recessed structure recessed towards the display unit 100 (e.g., Figure 3 (As shown).

[0084] The operating part 342 extends to the outer circumferential side of the enclosure part 312. The assembly personnel can hold the operating part 342 and move it relative to the first connector 310.

[0085] The enclosure 312 has a connecting hole on its side wall for the operation part 342 to extend out. The connecting hole extends vertically along the display device 10, so that the adjustment member 340 can move relative to the first connector 310 along the vertical direction of the display device 10.

[0086] As an optional implementation, the display device 10 further includes a first elastic element 350, which includes, but is not limited to, a spring. The first elastic element 350 connects the first connector 310 and the second connector 320. The direction of the elastic force of the first elastic element 350 is parallel to the relative sliding direction of the first connector 310 and the second connector 320. The direction of the elastic force of the first elastic element 350 is related to the orientation of the large end of the wedge cavity. It is used to cause the rolling element 330 to move toward the small end of the wedge cavity when the first connector 310 and the second connector 320 are moved relative to each other.

[0087] For example, when the larger end of the wedge cavity faces the display unit 100, the first elastic member 350 is compressed between the first connector 310 and the second connector 320. The first elastic member 350 allows the first connector 310 and the second connector 320 to move away from each other. For instance, when the support unit 200 is in a fixed connection state, under the elastic force of the first elastic member 350, the first connector 310 can move away from the second connector 320. Thus, when the adjustment unit 300 is in a locked state, under the elastic force of the first elastic member 350, the rolling member 330 still has a tendency to move towards the smaller end of the wedge cavity. The rolling member 330 can be effectively clamped between the cavity wall of the wedge cavity and the side wall of the insertion part 321, resulting in high connection stability of the adjustment unit 300.

[0088] Furthermore, when the assembly personnel adjust the installation height of the display unit 100 or install the display unit 100, they can release the display unit 100, and the display unit 100 can move away from the support unit 200 under the elastic force of the first elastic member 350, so that the adjustment unit 300 switches to the locked state, making the operation more labor-saving.

[0089] Furthermore, when the adjustment unit 300 is in the adjustment state, the first connector 310 and the second connector 320 are in a flexible connection state. When the second connector 320 is connected to or disconnected from the support unit 200, the instantaneous movement of the second connector 320 can be buffered by the first elastic member 350, effectively preventing the display unit 100 from being subjected to rigid collisions, and the display unit 100 has a high level of safety.

[0090] As an optional implementation, the display device 10 further includes a second elastic element 360, which includes, but is not limited to, a spring. The second elastic element 360 connects the adjusting member 340 and the first connecting member 310, and the elastic force of the second elastic element 360 is directed towards the rolling member 330. Thus, when assembling or disassembling the display unit 100 or adjusting its installation height, the assembler needs to overcome the elastic force of the second elastic element 360 and move the adjusting member 340. Furthermore, when the assembler releases the adjusting member 340, it automatically moves towards the smaller end of the wedge-shaped cavity under the elastic force of the second elastic element 360, making the operation more labor-saving and convenient.

[0091] Furthermore, when the adjustment unit 300 is in the locked state, under the elastic force of the second elastic member 360, the adjustment member 340 can press the rolling member 330 against the small end of the wedge cavity, so that the rolling member 330 can be effectively clamped between the cavity wall of the wedge cavity and the side wall of the insertion part 321, and the connection stability of the adjustment unit 300 is high.

[0092] Meanwhile, by setting the adjustment member 340 and the second elastic member 360, the locking failure of the adjustment unit 300 can be avoided due to accidental touch of the display unit 100. In this embodiment, the display unit 100 can be effectively installed on the support unit 200.

[0093] In some embodiments, the display device 10 may be provided with a first elastic element 350 and a second elastic element 360 simultaneously, which makes operation convenient and labor-saving, and the display unit 100 has high safety.

[0094] As an alternative implementation, the second connector 320 can also be a telescopic member, so that the second connector 320 has a variable length dimension. At the same time, in conjunction with the adjustable relative fixed position between the first connector 310 and the second connector 320, the display unit 100 can have a large range of installation height adjustment.

[0095] As an optional implementation, the second connector 320 includes a fixing part 322 and a connecting part 323. The fixing part 322 is detachably connected to the support unit 200, that is, the fixing part 322 can be connected to the support unit 200 by means of screwing, snap-fitting, etc. The connecting part 323 is slidably connected to the first connector 310, that is, the insertion part 321 is disposed on the connecting part 323. For example, the end of the connecting part 323 constitutes the insertion part 321 (e.g., Figure 3 As shown, the fixing part 322 and the connecting part 323 are detachably connected, for example, by a threaded connection. For example, the connecting part 323 is provided with a threaded hole, and the fixing part 322 is provided with a stud. In this way, the extension height of the fixing part 322 relative to the connecting part 323 can be adjusted by screwing the fixing part 322 and the connecting part 323 together, making the operation more convenient.

[0096] As an optional implementation, the fixing part 322 includes a magnetic element, such as a magnet, and the fixing part 322 is provided with a mounting cavity for mounting the magnetic element. The magnetic element is used to be attracted and fixed to the support unit 200. In this case, the support unit 200 is provided with a magnetic structure that can be attracted and fixed to the magnetic element, such as a magnet or a metal part that can be magnetically attracted.

[0097] In this way, the second connector 320 can be fixed to the support unit 200 by the attraction between the magnetic component and the support unit 200. By applying force to resist the magnetic force between the magnetic component and the support unit 200, the second connector 320 can be separated from the support unit 200, which is convenient to operate.

[0098] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
