Description

Technical Field

[0001] This application belongs to the technical field of COB displays, and more specifically, relates to a connection component and a display device. Background Technology

[0002] COB (Chip On Board) displays are large-size screens composed of multiple display modules. When in use, each display module displays different images or colors, which are then combined to form a complete display screen. They are widely used in commercial advertising, conference presentations, stage performances and other fields.

[0003] Because large, assembled screens are difficult to transport, display modules typically need to be transported to the installation site for splicing and assembly. Currently, during the splicing process of display modules at the installation site, adjacent display modules are usually first connected and fixed with connecting components or structures, and then the light panels are installed on the cabinet. This process results in low installation efficiency and poor splicing accuracy.

[0004] Therefore, existing COB displays suffer from low splicing efficiency and poor splicing accuracy. Summary of the Invention

[0005] The purpose of this application is to provide a connection component and a display device to solve the defects of low splicing efficiency and poor splicing accuracy of COB displays in the prior art.

[0006] To achieve the above objectives, in a first aspect, this application provides a connection component for connecting two display modules stacked and connected along a first direction, comprising:

[0007] The locking structure includes two locking members and a guide member connected between the two locking members, wherein at least one locking member is slidably connected to the guide member along a first direction; each locking member is used to connect a corresponding display module, and the locking member has a first guide slope, the first guide slopes of the two locking members are arranged along the first direction and are opposite to each other, the distance between the first guide slopes of the two locking members in the first direction gradually increases along the driving direction, and the driving direction is perpendicular to the first direction;

[0008] The tightening member has two second guide slopes arranged along the first direction and facing each other, the distance between the two second guide slopes in the first direction gradually increases along the driving direction; each second guide slope slides against the corresponding first guide slope.

[0009] The driving component is connected to the tightening component and is used to drive the tightening component to move along the driving direction, and to apply a locking force to the corresponding first guide slopes to the two locking components to move closer to each other in the first direction.

[0010] In some embodiments of the first aspect, each of the locking members has a mounting surface, the two mounting surfaces of the two locking members face each other in the first direction, one end of the guide member is fixedly connected to one of the mounting surfaces, and the other end is slidably connected to the other mounting surface.

[0011] In some embodiments of the first aspect, the locking member includes:

[0012] The first screw part is threadedly connected to the tightening member;

[0013] The first nut portion is connected to the first screw portion and abuts against the side of the locking structure opposite to the tightening member.

[0014] In some embodiments of the first aspect, the connecting assembly further includes a first reset member connected between the locking structure and the tightening member, the first reset member being capable of generating a second reset force that drives the tightening member to move away from the driving direction when the tightening member moves along the driving direction.

[0015] In some embodiments of the first aspect, the connecting assembly further includes a second reset member connected between the two locking members for applying a second reset force opposite to the first direction to the two locking members.

[0016] In some embodiments of the first aspect, the connecting assembly further includes a limiting member connected between the locking structure and the tightening member, for limiting the maximum distance between the locking structure and the tightening member.

[0017] In some embodiments of the first aspect, the limiting member includes:

[0018] The second screw portion is threadedly connected to one of the locking components;

[0019] The second nut portion is connected to the second screw portion and is located on the side of the tightening member facing away from the locking structure.

[0020] In some embodiments of the first aspect, the tightening member has a through hole extending in the driving direction, and the inner wall of the through hole is provided with an annular flange; the second screw portion passes through the inner side of the annular flange and can slide within the annular flange along the first direction;

[0021] The second nut portion is slidably connected to the through hole along the first direction and is located on the side of the annular flange facing away from the locking structure; and the distance between the second nut portion and the opening of the through hole facing away from the locking structure is greater than or equal to the maximum distance between the tightening member and the locking structure.

[0022] In some embodiments of the first aspect, the locking member has a guide groove on the side facing the tightening member, and the inner wall surfaces of the adjacent guide grooves on the two locking members respectively form a first guide slope.

Simultaneously, the two locking members can slide along the first direction under the connection of the guide member, and the relative sliding of the first guide slope and the second guide slope drives the two locking members closer to each other, thereby applying a locking force to the two display modules, realizing the rapid connection of the two display modules, improving the installation efficiency of the display device, and improving the splicing accuracy between display modules, reducing the likelihood of splicing gaps. Furthermore, the display device of this application, by adopting the above-mentioned connection component, also has the advantages of high splicing efficiency and good splicing accuracy, and is suitable for various occasions requiring large-size display screens.

Therefore, they should not be construed as limitations on this application.

[0046] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0047] Reference Figures 1-11 This application provides a display device, including a display component 100 and a connection component 200.

[0048] Reference Figure 1 , Figure 2 and Figure 3The display assembly 100 includes multiple display units 110 arranged along a first direction, and each display unit 110 includes multiple display modules 101 arranged along a second direction, the first direction being perpendicular to the second direction. In this embodiment, the first direction is horizontal and the second direction is vertical. That is, a certain number of display modules 101 are first arranged vertically and connected to each other to form display units 110, and then multiple display units 110 are arranged horizontally and connected to each other to form the entire display assembly 100, so that the entire display assembly 100 is composed of multiple display modules 101 arranged in a matrix. Adjacent display units 110 are connected and fixed together by at least one connecting component 200.

[0049] In practical applications, a predetermined number of display modules 101 can be assembled in the factory along the second direction to form multiple display units 110. Each display unit 110 is elongated and its size is suitable for transportation. The multiple display units 110 are then transported to the installation site, where they are assembled along the first direction using connecting components 200 to form the entire display assembly 100. Then, the edge-wrapping components and the mounting bracket components are installed in sequence to reduce the assembly difficulty at the installation site and improve work efficiency.

[0050] The display module 101 is used to display images and may include a housing and components such as a light panel, a receiver card, and a power supply disposed within the housing. The display module 101 has a display surface 101a and a backlight surface 101b facing each other in a third direction, with both the first and second directions perpendicular to the third direction. In this embodiment, the third direction is a horizontal direction perpendicular to the first direction. The display surface 101a is the front surface of the display module 101, and the backlight surface 101b is the back surface of the display module 101. The display surface 101a is used to display images, and the backlight surface 101b is used to connect components such as mounting brackets or to be fixed to the building facade.

[0051] Reference Figure 4 and Figure 5 The display module 101 also has two first connecting surfaces 101c facing each other in the second direction. The two first connecting surfaces 101c can be arranged symmetrically. When multiple display modules 101 are connected along the second direction to form a display unit 110, the two first connecting surfaces 101c facing each other in two adjacent display modules 101 in the second direction abut against each other.

[0052] Each of the two first connecting surfaces 101c can be provided with a first connecting structure, which is used to achieve a stable connection between two adjacent display modules 101 in the second direction. The first connecting structure may include a snap-fit ​​structure, a bolt connection structure, a magnetic connection structure, a pin connection structure, etc., to position and connect the display modules 101 in the second direction, so as to stabilize the structure of the pre-assembled display unit 110.

[0053] Furthermore, electrical connection structures can be provided on the two first connection surfaces 101c, so that when two adjacent display modules 101 in the second direction are connected, their internal circuits are electrically connected through the electrical connection structures, thereby enabling continuous display of images on each display module 101. The electrical connection structures can be pluggable electrical connectors, elastic contact pieces, or any other structural form capable of transmitting electrical signals.

[0054] The display module 101 also has two second connecting surfaces 101d facing each other in the first direction. When multiple display units 110 are connected along the first direction to form a display assembly 100, the two second connecting surfaces 101d facing each other in two adjacent display modules 101 in the first direction abut against each other.

[0055] The two second connecting surfaces 101d can also be provided with second connecting structures to position the connection between the two adjacent display units 110, ensure the relative position of the display modules 101 at the same height in the two adjacent display units 110, and thus ensure the continuity and accuracy of the image display on the entire display assembly 100.

[0056] For example, one of the second connecting surfaces 101d has a protruding positioning post, and the other second connecting surface 101d has a positioning hole. The shapes of the positioning hole and the positioning post match, and the orthographic projection of the positioning post on the second connecting surface 101d falls into the positioning hole. When two adjacent display units 110 are spliced ​​together in the first direction, the positioning post can be accurately inserted into the positioning hole facing it, realizing the position positioning of the two adjacent display units 110 in the first direction. The number of positioning posts and positioning holes can be one or more.

[0057] A connecting component 200 is disposed between two adjacent display units 110 and is used to apply a locking force that brings the two display units 110 closer together in a first direction, thereby achieving a quick connection between the two display units 110. The connecting component 200 can be connected to two adjacent display units 110, or between two adjacent display modules 101 in the first direction. For example, the connecting component 200 can be connected to the uppermost and lowermost display modules 101 of the two display units 110.

[0058] Reference Figures 6-11The connecting assembly 200 includes a locking structure, a tightening member 240, and a driving member 250. The locking structure includes two locking members 210 and a guide member 220 connecting the two locking members 210. Each of the two locking members 210 corresponds to one of the two connected display modules 101, and the locking members 210 are used to connect the corresponding display modules 101. At least one of the two locking members 210 is slidably connected to the guide member 220 along a first direction, so that the two locking members 210 can slide relative to each other in the first direction. Each locking member 210 has a first guide ramp 210a, and the two first guide ramps 210a on the two locking members 210 are arranged in the first direction and are positioned opposite each other, and the distance between the two first guide ramps 210a in the first direction gradually increases along the driving direction.

[0059] The tightening member 240 is located on one side of the locking structure and has two second guide ramps 240a arranged and facing each other in the first direction. The distance between the two second guide ramps 240a in the first direction also gradually increases along the driving direction. Each second guide ramp 240a can slide and abut against the corresponding first guide ramp 210a. The driving direction is the direction in which the tightening member 240 moves toward the locking structure. The driving direction can be perpendicular to both the first and second directions, that is, the tightening member 240 moves toward the locking structure along a direction perpendicular to the relative sliding of the two locking members 210.

[0060] The driving member 250 is connected to the tightening member 240 in a transmission manner, and is used to drive the tightening member 240 to move along the driving direction, and to make the two second guide slopes 240a apply a locking force to the corresponding first guide slopes 210a respectively, so as to drive the two locking members 210 to move closer to each other in the first direction, thereby applying a locking force to the two display modules 101 connected by the two locking members 210 to move closer to each other in the first direction, so as to realize the rapid connection of the two adjacent display units 110 in the first direction.

[0061] The locking member 210 can be connected to the first connecting surface 101c of the uppermost or lowermost display module 101 in the display unit 110. The connection between the locking member 210 and the first connecting surface 101c can be any combination of one or more methods such as plug-in connection, snap-fit ​​connection, bolt connection, so that when the two locking members 210 slide in a direction that approaches each other, they drive the two display modules 101 to approach each other, that is, apply a locking force in the first direction to the two display modules 101, thereby realizing the rapid connection of the two adjacent display units 110 in the first direction.

[0062] Reference Figure 6 and Figure 7The locking member 210 may include a sliding portion 211 and a hook portion 212 connected to one end of the sliding portion 211. The sliding portion 211 may be L-shaped, and the two sliding portions 211 of the two locking members 210 are arranged in opposite directions and fit together to make the sliding connection of the two sliding portions 211 more compact and stable. The hook portion 212 may be provided at the opposite ends of the two sliding portions 211. The hook portion 212 may be an L-shaped protrusion protruding downward relative to the sliding portion 211, with its end opposite to the sliding portion 211 forming a hook head bent towards the body of the sliding portion 211, so that it can hook onto the corresponding display module 101.

[0063] The surface of the display module 101 facing the locking member 210 may have a hook groove 1011. The hook groove 1011 is a groove structure that matches the shape of the hook part 212. By hooking the hook part 212 into the hook groove 1011 and fitting and limiting it with the inner wall surface of the hook groove 1011, the locking member 210 and the corresponding display module 101 can be quickly connected.

[0064] Specifically, the hook groove 1011 can be formed on the first connecting surface 101c of the display module 101. When multiple display modules 101 are connected along the second direction to form a display unit 110, the uppermost or lowermost end face of the display unit 110 has a hook groove 1011 that cooperates with the hook part 212, so that the locking member 210 can be connected to the upper or lower end face of the display unit 110. Further, each first connecting surface 101c is provided with two hook grooves 1011, and the two hook grooves 1011 are respectively located on both sides of the first connecting surface 101c in the first direction, so that a connecting component 200 can be used on both sides of the same display unit 110 to connect with the adjacent display unit 110.

[0065] The guide member 220 can be a rod-shaped structure extending along the first direction, such as a guide pin, guide post, or guide rod. The guide member 220 is disposed between the two locking members 210 to provide guidance for the relative sliding of the two locking members 210. Both ends of the guide member 220 can be fixedly connected to the two locking members 210 respectively; or one end of the guide member 220 can be fixedly connected to one locking member 210, and the other end can be slidably connected to the other locking member 210, so that the guide member 220 is slidably connected to at least one of the two locking members 210, thereby realizing the relative sliding of the two guide members 220 in the first direction.

[0066] In some embodiments, the two locking members 210 may have mounting surfaces 210b, the two mounting surfaces 210b on the two locking members 210 are spaced apart and face each other in a first direction, one end of the guide member 220 is fixedly connected to one of the mounting surfaces 210b, and the other end is slidably connected to the other mounting surface 210b.

[0067] The mounting surface 210b can be a plane, a curved surface, or any irregularly shaped surface adapted to the connection method. When the mounting surface 210b is a plane, it can be perpendicular to the first direction. One end of the guide member 220 can be fixedly connected to the mounting surface 210b of one of the locking members 210 by means of insertion, snap-fit, adhesive, threaded connection, or integral connection. The other end of the guide member 220 can be slidably connected to the mounting surface 210b of the other locking member 210 by means of a sliding hole 2102 structure, a sliding groove structure, or a sliding rail structure.

[0068] For example, the two mounting surfaces 210b can be two end faces of two sliding parts 211 facing each other in the first direction. One sliding part 211 has a mounting hole on its mounting surface 210b, and a guide pin 220 is inserted into the mounting hole with an interference fit at one end to be fixedly connected to the locking member 210. The other sliding part 211 has a sliding hole 2102 on its mounting surface 210b, and the guide pin is connected to the sliding hole 2102 with a clearance fit, allowing the guide pin to slide within the sliding hole 2102, thereby achieving relative sliding of the two locking members 210 in the first direction.

[0069] The first guide slope 210a is an inclined surface on the locking member 210 that has a certain angle of inclination with the first direction. For example, a guide groove 2101 may be provided on the side of the locking member 210 facing the tightening member 240. The inner wall surfaces of the two guide grooves 2101 on the two locking members 210 that are close to each other are inclined relative to the first direction, so as to form two first guide slopes 210a arranged in the first direction and facing each other.

[0070] The second guide slope 240a is a surface on the tightening member 240 parallel to the first guide slope 210a. The two second guide slopes 240a can be two end faces of the tightening member 240 facing each other in the first direction. For example, when a guide groove 2101 is formed on the locking member 210, and the first guide slope 210a is formed by the inner wall surface of the guide groove 2101, the tightening member 240 can include a support portion 241 and two protrusions 242 protruding from one side of the support portion 241. The support portion 241 can be a rod-shaped member extending in the first direction, and the protrusions 242 protrude from the surface of the support portion 241 facing the locking structure. The positions of the two protrusions 242 correspond to the guide grooves 2101 on the two locking members 210, and the shapes of the protrusions 242 match the shapes of the guide grooves 2101. The two facing sidewalls of the two protrusions 242 are parallel to the first guide slope 210a in the corresponding guide groove 2101, so that two second guide slopes 240a are formed by the two facing sidewalls of the two protrusions 242. The protrusions 242 are slidably inserted into the corresponding guide grooves 2101 along the driving direction, so that the corresponding first guide slopes 210a and second guide slopes 240a slide against each other.

[0071] The distance between the two first guide ramps 210a and the two second guide ramps 240a in the first direction gradually decreases along the driving direction. The driving direction is the direction in which the tightening member 240 is away from the locking structure, and it is perpendicular to both the first and second directions. As the tightening member 240 moves toward the locking structure along the driving direction, the two second guide ramps 240a contact the two first guide ramps 210a respectively. As the distance between the locking structure and the tightening member 240 gradually decreases, the two first guide ramps 210a are driven to move closer to each other under the action of the corresponding second guide ramps 240a. This causes the two locking members 210 to be driven closer to each other, thereby driving the two display units 110 to move closer to each other and connect tightly.

[0072] The inclination angle of the first guide slope 210a can be 30° to 60° to ensure smooth sliding and moderate locking force between the first guide slope 210a and the second guide slope 240a.

[0073] The driving component 250 is a component that can generate driving force, causing the tightening component 240 to perform linear reciprocating motion under the action of the driving force, so that the tightening component 240 moves closer to the locking structure along the driving direction or moves away from the locking structure in the opposite direction of the driving direction.

[0074] For example, the driving member 250 may be a bolt, including a first screw portion 251 and a first nut portion 252 connected to one end of the first screw portion 251. The tightening member 240 may have a first threaded hole in the middle part of the two protrusions 242, and the first screw portion 251 is threadedly connected to the first threaded hole. The first nut portion 252 may be provided with a cross-shaped, slotted, or star-shaped rotating groove to facilitate rotation of the nut portion using a screwdriver or other tools. Preferably, the first nut portion 252 may have a hexagonal rotating groove to facilitate rotation of the nut portion using a hex wrench or other tools. The first nut portion 252 may abut against the side of the locking structure opposite to the tightening member 240. When the driving member 250 rotates, since the first nut portion 252 is confined to one side of the locking structure, the first screw portion 251 will rotate relative to the first threaded hole and move along its axial direction, thereby driving the tightening member 240 to move toward the locking structure.

[0075] In some embodiments, both locking members 210 may have slots 2111, and the two slots 2111 on the two locking members 210 at least partially overlap in the driving direction. The first screw portion 251 is movably inserted into the two slots 2111 so that the first nut portion 252 of the lock abuts against the side of the locking structure away from the tightening member 240.

[0076] The slot 2111 is an elongated through-hole 2401 extending through the locking member 210 in the driving direction, and it extends along the first direction. Specifically, the slot 2111 can be formed on the sliding portion 211 of the locking member 210. When the two sliding portions 211 are engaged, at least a portion of the slots 2111 on the two sliding portions 211 overlap to allow the first bolt portion to pass through, and to allow the first nut portion 252 to abut against the surface of the locking member 210 facing away from the tightening member 240 in the locking structure. The slot 2111 allows the locking member 210 and the first screw portion 251 to slide relative to each other in the first direction by a certain distance, without interfering with the movement of the locking member 210.

[0077] Reference Figure 6In actual construction, the two display units 110 are first spliced ​​together along the first direction, and then the two locking members 210 in the connecting assembly 200 are hooked into the hook grooves 1011 of the two display units 110 respectively. At this time, the first guide slope 210a on the two locking members 210 slides against the second guide slope 240a on the tightening member 240, but no locking force is applied to the two display units 110. Subsequently, the tightening member 240 is moved toward the two locking members 210 by rotating the driving member 250. During the movement of the tightening member 240, the first guide slope 210a and the second guide slope 240a slide relative to each other. Since the distance between the two in the first direction gradually decreases, the two locking members 210 are driven to move closer to each other in the first direction. During this process, the hook part 212 on the locking member 210 slides in the hook groove 1011 and applies a pushing force to the display module 101, thereby applying a locking force to bring the two display units 110 closer to each other. Conversely, the reverse rotation drive 250 can cause the tightening member 240 to move away from the two locking members 210. After the two locking members 210 lose the restraint of the tightening member 240, they can move away from each other in the first direction, thereby releasing the locking of the two display units 110 and facilitating the disassembly or adjustment of the display assembly 100. Since the threaded connection between the screw and the tightening member 240 has a self-locking characteristic, the tightening member 240 can maintain its current position after rotation stops, avoiding the weakening of the locking force of the two locking members 210 due to external interference.

[0078] The first nut 252 of the driving component 250 can be located on the side of the locking component 210 facing the display surface 101a of the display module 101, and the tightening component 240 is located on the side of the locking component 210 facing the backlight surface 101b of the display module 101. When splicing multiple display units 110 on the installation site, the workers only need to rotate the first nut 252 on the side of the display surface 101a to connect two adjacent display units 110. The workers have a larger working space, which improves the convenience of on-site construction operations.

[0079] In some embodiments, the connecting assembly 200 may further include a first reset member 230, which is connected between the locking structure and the tightening member 240. When the tightening member 240 moves toward the locking structure, it can generate a first reset force that drives the tightening member 240 to move in the opposite driving direction, so as to drive the tightening member 240 away from the locking structure.

[0080] The first reset member 230 can be an elastic element, such as a spring or elastic rubber. When the tightening member 240 moves toward the locking structure, the elastic element is compressed and stores force, thereby generating a first reset force that drives the tightening member 240 away from the locking structure. The first reset member 230 can also be two magnets with the same magnetic poles facing each other, respectively disposed on the locking structure and the tightening member 240. When the tightening member 240 moves toward the locking structure, the two magnets repel each other, generating a first reset force that drives the tightening member 240 away from the locking structure.

[0081] By setting a first reset member 230 between the tightening member 240 and the locking structure, when the drive member 250 is rotated in the opposite direction, the first reset force can be used to drive the tightening member 240 and the locking structure to automatically move away from each other, so that the two locking members 210 can move away from each other and the locking force on the two display modules 101 can be released, thereby realizing the quick disassembly of the two adjacent display units 110.

[0082] For example, the first reset member 230 is a spring, and it is disposed between the locking member 210 and the tightening member 240 on the side near the tightening member 240. The first reset member 230 can be sleeved on the first screw portion 251 of the driving member 250 to guide the deformation of the first reset member 230. Further, the locking member 210 may have a first receiving groove 2103 on the side facing the tightening member 240, and a portion of the first reset member 230 can be embedded in the first receiving groove 2103, making the overall structure of the connecting assembly 200 more compact, and providing a receiving space for the compressed first reset member 230 when the tightening member 240 and the locking structure are in the locked state.

[0083] In some embodiments, the connecting assembly 200 may further include a second reset member 260, which is connected between two locking structures and is used to apply a second reset force opposite to each other in a first direction to the two locking members 210.

[0084] The second reset member 260 can also be an elastic element such as a spring or elastic rubber, with its two ends respectively connected to the facing surfaces of the two locking members 210. When the two locking members 210 approach each other in the first direction, the second reset member 260 is compressed and stores force; when the tightening member 240 moves away from the two locking members 210, the second reset member 260 releases the stored force, generating a second reset force that drives the two locking members 210 away from each other. The second reset member 260 can also be two magnets with the same magnetic poles facing each other, respectively disposed on the two locking members 210. When the two locking members 210 approach each other, the two magnets repel each other, generating a second reset force that drives the two locking members 210 away from each other. The provision of the second reset member 260 enables the two locking members 210 to automatically separate when the tightening member 240 moves away from the locking structure, further improving the ease of disassembly of the connecting assembly 200.

[0085] For example, the second reset member 260 can be a spring. The second reset member 260 can be sleeved on the guide member 220, and its two ends can respectively abut against the two mounting surfaces 210b of the two locking members 210 to provide guidance for the deformation of the second reset member 260. Further, a second receiving groove 2104 can also be formed on the mounting surface 210b with the sliding hole 2102. Part of the second reset member 260 is embedded in the second receiving groove 2104. When the two locking members 210 are in the locked state, the compressed second reset member 260 can be placed in the second receiving groove 2104 to ensure that the minimum distance between the two locking members 210 moving close together is smaller, thereby strengthening the locking force on the two display units 110.

[0086] In one embodiment, the connecting assembly 200 may further include a limiting member 270, which limits the maximum distance between the tightening member 240 and the locking structure when the tightening member 240 moves away from the locking structure.

[0087] The limiting member 270 can be a limiting pin, limiting post, or limiting rod connected between the tightening member 240 and the locking structure. The limiting member 270 can be fixed relative to one of the tightening member 240 and the locking structure, and restrict sliding relative to the other. For example, one end of the limiting member 270 can be fixed relative to the locking member 210 in the locking structure, and the other end can slide relative to the tightening member 240. The limiting member 270 can have a limiting structure. When the tightening member 240 moves away from the locking structure to a preset position, the limiting structure can abut against the side of the tightening member 240 away from the locking structure to limit the distance between the tightening member 240 and the locking structure from increasing further, preventing the protrusion 242 from disengaging from the guide groove 2101, which would cause the connection between the two display units 110 to be unstable, and making the connecting assembly 200 more stable and less prone to loosening when in the unlocked state.

[0088] In some embodiments, bolts can also be used as limiting members 270. The limiting member 270 may include a second screw portion 271 and a second nut portion 272 connected to one end of the second screw portion 271. The second screw portion 271 may be threadedly connected to one of the locking members 210, and the second nut portion 272 may abut against the side of the tightening member 240 opposite to the locking structure.

[0089] Specifically, one of the locking components 210 may have a second threaded hole, and the second screw portion 271 is threadedly connected to the second threaded hole. The tightening component 240 may have a through hole 2401 extending in the driving direction. The through hole 2401 may extend along a first direction, and the second screw portion 271 may be movably inserted into the through hole 2401 so that the second screw portion 271 can move along the first direction within the through hole 2401, avoiding interference with the movement of the locking component 210. The second nut portion 272 abuts against the side of the tightening component 240 facing away from the locking structure. When the tightening component 240 moves away from the locking structure to the maximum distance position, the second nut portion 272 abuts against the surface of the tightening component 240, thereby limiting the maximum distance between the tightening component 240 and the locking structure. Furthermore, through the threaded connection between the second screw portion 271 and the locking member 210, the distance between the second nut portion 272 and the locking member 210 can be adjusted by rotating the limiting member 270, thereby adjusting the maximum distance between the tightening member 240 and the locking structure, which also facilitates the overall assembly of the connecting assembly 200.

[0090] The second nut portion 272 may also be provided with a rotating groove to facilitate rotation using tools such as screwdrivers. Preferably, the second nut portion 272 has a hexagonal rotating groove to facilitate rotation of the limiting member 270 using tools such as hex wrenches.

[0091] In some embodiments, the second nut portion 272 is slidably connected to the through hole 2401 along a first direction, and an annular flange 2411 may protrude from the through hole 2401. The second screw portion 271 passes through the inner side of the annular flange 2411 and can slide along the first direction on the inner side of the annular flange 2411. The second nut portion 272 may abut against the side of the annular flange 2411 facing away from the locking structure. The distance between the nut portion and the opening of the through hole 2401 facing away from the locking structure may be greater than or equal to the maximum distance between the tightening member 240 and the locking structure, so that when the tightening member 240 moves towards the locking structure in the driving direction to the locked state, the second nut portion 272 will not protrude from the opening of the through hole 2401 facing away from the locking structure, avoiding interference of the second nut portion 272 with other components of the display device, and also making the overall structure of the connecting assembly 200 more compact and aesthetically pleasing.

[0092] Reference Figure 1 and Figure 2 The display device may also include an edge-covering component, which is used to surround the periphery of the display component 100, shielding the sidewalls of the display modules 101 located at the edge of the display component 100, thereby further reinforcing the structure of each display module 101 in the display component 100 and beautifying the overall appearance.

[0093] Reference Figure 2In some embodiments, the edging assembly may include a first edging and a plurality of second edgings, the first edging and the plurality of second edgings together surrounding the periphery of the display assembly 100, and the first edging having a receiving cavity 1. The display device also includes electronic components disposed within the receiving cavity 1.

[0094] The total number of first and second edging edges is the same as the number of sidewalls around the display component 100. The first edging edges and multiple second edging edges are connected to different positions on the display component 100, and can be adapted to the installation requirements of the display component 100. In this embodiment, the display component 100 is rectangular in shape and has four sidewalls around its perimeter. The edging assembly includes one first edging edge and three second edging edges. The first edging edge is installed on the lower surface of the display component 100, and the three second edging edges are respectively installed on the upper surface and the left and right side surfaces of the display component 100.

[0095] The first edge can be fixed to the lower surface of the display component 100 by means of snap-fit, fastener connection, etc. The receiving cavity is a hollow structure set in the first edge, used to house the electronic components required by the display component 100. The electronic components are electronic devices used to control the display of the display module 101 in the display device or to perform other related operations, such as an audio module for playing audio or a wireless communication module for wireless communication with the display component 100; the electronic components can also be cable circuits used to electrically connect two adjacent display units 110. By setting a receiving cavity in the first edge, installation space is provided for the electronic components used with the display component 100, facilitating the installation and maintenance of the electronic components.

[0096] The second edging can be a strip-shaped plate structure that matches the side shape of the display component 100, and can be detachably connected to the display component 100 by means of plugging or other methods. For example, the display component 100 has a plugging hole 1012 on the side wall facing the second edging, and the second edging has an elastic buckle that can be inserted into the plugging hole 1012, so that the second edging can be detachably connected to the display module 101 by the plugging and cooperation of the elastic buckle and the plugging hole 1012.

[0097] The display device may also include a mounting bracket assembly for installation at the display device's mounting location. The mounting bracket assembly can be a frame-type support structure or a pole-type structure. For example, a mounting bracket assembly may include two horizontal beams and two vertical beams, which are joined together to form a rectangular frame structure. The mounting location for fixing the display device can be a wall, column, or other stable building structure, or it can be a dedicated mounting bracket. The horizontal or vertical beams can be fixed to the mounting location using fasteners such as expansion bolts.

[0098] At least one display module 101 may have a hook 120 on its backlight surface 101b. The hook 120 may be an L-shaped metal hook, the bending angle of which matches the cross-sectional shape of the beam of the bracket assembly. The beam in the bracket assembly may be designed as a guide rail structure with a transverse groove, allowing the hook 120 to be finely adjusted in the horizontal direction. The hook 120 may be connected to the backlight surface 101b of the display module 101 by bolts, welding, or other fixing methods to ensure a stable connection. In this embodiment, the backlight surface 101b of the display module 101 has several fixing holes 1013, which allow the hook 120 to be fixed to the backlight surface 101b using bolts.

[0099] When installing the display device, after the operator assembles the display component 100, the hook 120 can be installed at the corresponding position on the display component 100, and then the hook 120 can be hung on the bracket assembly to achieve stable installation of the display device. The installation process is simple and quick, and can be adjusted according to different installation environments, which improves the flexibility and adaptability of the installation.

[0100] Reference Figure 2 In some embodiments, the display device may further include a control component disposed on the backlight surface 101b of any one or more display modules 101 in the display component 100.

[0101] The control component is an electronic module used to control the display component 100. The control component may include a control box and a circuit board installed within the control box. The circuit board integrates a control chip for controlling the display of the display module 101 and other necessary electronic components. The control component can be electrically connected to each display module 101 and electronic component in the display component 100 via cables to achieve functions such as controlling the display content of the display module 101, adjusting display brightness, and receiving external signal input.

[0102] The location of the control component can be flexibly adjusted according to the actual needs of the display device and the installation space. In this embodiment, the control component is installed on a row of display units 110 near the side, and the connecting cables on the display units 110 are electrically connected to the control component, enabling the control component to uniformly control all display modules 101 in the entire display assembly 100. The placement of the control component not only facilitates operation and maintenance but also ensures the overall aesthetics of the display device. Furthermore, the control component can be designed as a detachable structure to facilitate replacement or upgrades according to actual needs.

[0103] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
