Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of display screens, and more particularly to a display module and a display device. BACKGROUND

[0002] At present, some large display screens are formed by splicing multiple display modules to realize the display effect of a large-size picture. In order to prevent the display modules from being accidentally separated during splicing, a magnet is usually arranged on the side of the display module to fix two adjacent display modules above and below by magnetic attraction. However, in order to ensure that the two display modules have sufficient magnetic attraction, the magnetic force of the two magnets is usually designed to be large, which results in the need to exert a large external force when disassembling the display modules, which not only makes disassembly difficult, but also easily causes damage to the display modules. SUMMARY

[0003] The purpose of the embodiments of the present application is to provide a display module and a display device to solve the technical problem that the magnetic attraction between two adjacent display modules is large in the prior art, which makes disassembly difficult.

[0004] To achieve the above-mentioned purpose, the first aspect of the present application provides a display module, comprising: a box body having at least one connecting surface, the connecting surface being used to connect another display module; a magnetic attraction member arranged on the connecting surface and in sliding connection with the box body, the magnetic attraction member being used to magnetically attract another display module connected with the connecting surface; a driving member connected with the magnetic attraction member and used to drive the magnetic attraction member to slide in the direction of approaching or moving away from the connecting surface.

[0005] Through the above technical solution, two adjacent display modules can be magnetically connected and positioned by the magnetic attraction member. During disassembly, the driving member can be used to drive the magnetic attraction member to slide away from the connecting surface, thereby increasing the distance between the magnetic attraction member and the adjacent display module, reducing the magnetic attraction between the magnetic attraction member and the adjacent display module, and further reducing the difficulty of disassembly. Moreover, the reduction of the magnetic attraction will not cause the display module to be accidentally separated due to the complete disappearance of the magnetic attraction, thereby ensuring the safety during disassembly.

[0006] In some embodiments of the first aspect, the box body is provided with a mounting cavity, and the magnetic attraction member is in sliding connection within the mounting cavity.

[0007] Through the above technical solution, the mounting cavity provides a stable mounting space for the magnetic attraction member, provides a space for the movement of the magnetic attraction member away from the connecting surface, and ensures the stability and directivity of the magnetic attraction member during sliding, thereby reducing the risk of movement deviation or jamming.

[0008] In some embodiments of the first aspect, the magnetic attraction member comprises: a shell slidingly connected in the mounting cavity, the driving member being connected with the shell, and the shell having a receiving cavity; a magnet arranged in the receiving cavity of the shell; a cover plate arranged on the shell and sealing the cavity opening of the receiving cavity.

[0009] According to the above technical solution, the magnet is embedded in the receiving cavity of the shell and is fixed and sealed by the cover plate, so that the loosening or falling off of the magnet during sliding is effectively avoided, the structural reliability is improved, and the wear or environmental corrosion problem caused by direct exposure of the magnet is also avoided, thereby further prolonging the service life of the magnetic member.

[0010] In some embodiments of the first aspect, at least one first guide structure is arranged on the inner wall surface of the mounting cavity, and at least one second guide structure is arranged on the outer wall surface of the shell, and the first guide structure and the second guide structure are slidingly matched.

[0011] According to the above technical solution, the sliding trajectory of the shell in the mounting cavity is effectively constrained by the sliding matching of the first guide structure and the second guide structure, the stability and precision of the movement of the magnetic member are further improved, the jamming or wear caused by deflection is avoided, and the driving member can efficiently and stably control the magnetic member to move away from or approach the connecting surface, so that the connection strength is ensured while convenient disassembly is realized.

[0012] In some embodiments of the first aspect, the shell is provided with a limiting groove, the box body is provided with a limiting member, at least part of the limiting member protrudes from the inner wall of the mounting cavity and is slidingly embedded in the limiting groove, so as to limit the sliding distance of the magnetic member in the mounting cavity.

[0013] According to the above technical solution, the sliding stroke of the magnetic member in the mounting cavity is effectively constrained by the cooperation of the limiting member and the limiting groove, the magnetic member is prevented from being separated from the mounting cavity or excessively displaced to cause structural damage, and the assembly safety is further improved.

[0014] In some embodiments of the first aspect, the driving member is threadedly connected with the magnetic member, so as to drive the magnetic member to slide when the driving member rotates.

[0015] According to the above technical solution, the magnetic member can be moved along the axial direction by the rotation of the driving member, and the convenience of driving the magnetic member to move is improved.

[0016] In some embodiments of the first aspect, the driving member is provided with a bolt hole, the magnetic member is provided with a threaded hole, and the display module further comprises a fastener, the fastener being rotatably arranged in the bolt hole and being threadedly connected in the threaded hole.

[0017] By using the above technical solution, fasteners are sequentially inserted through the bolt holes of the drive component and connected to the threaded holes of the magnetic component, achieving stable assembly between the drive component and the magnetic component. At the same time, relative rotational freedom is preserved, ensuring that the drive component can be effectively converted into linear sliding of the magnetic component when rotating, thereby improving transmission reliability.

[0018] In some embodiments of the first aspect, the display module further includes a rotating rod and a transmission component, the rotating rod being rotatably connected to the housing, the transmission rod being used to connect to a rotating rod of another display module, and the transmission component being connected between the rotating rod and the driving component, the transmission component being used to cause the transmission rod and the driving component to rotate synchronously.

[0019] Through the above technical solution, the rotating rod and the driving component are linked by the transmission component to realize the coordinated movement between multiple display modules. When the driving component at one end is driven to rotate, it can synchronously drive the magnetic component of another display module to move, so that the magnetic components of the two display modules can synchronously move closer to or away from the connection surface, thereby realizing the linkage control between multiple modules, improving the overall operation coordination and response efficiency, and meeting the usage requirements in complex installation environments.

[0020] In some embodiments of the first aspect, the display module further includes an elastic element disposed between the magnetic member and the housing, and used to apply a restoring force toward the connecting surface to the magnetic member when the driving member drives the magnetic member to move away from the connecting surface.

[0021] Through the above technical solution, the elastic element is compressed or stretched to store elastic potential energy when the magnetic component is away from the connecting surface. This allows the magnetic component to automatically or assistedly and quickly return to a position close to the connecting surface after being separated from another display module. Furthermore, the reset force provided by the elastic element can also enable the magnetic component to maintain a certain preload in the connected state, which enhances the stability and reliability of the connection and reduces the risk of accidental separation caused by vibration or external impact.

[0022] A second aspect of this application provides a display device comprising at least two display modules as described in the first aspect and any embodiment thereof, wherein two connecting surfaces of two adjacent display modules abut against each other, and two magnetic suction members are magnetically connected.

[0023] The above technical solution uses the magnetic connection of two magnetic components to achieve quick positioning and connection of two adjacent display modules. During disassembly, at least one of the magnetic components can be moved to increase the distance between the two magnetic components, thereby reducing the magnetic force and facilitating disassembly operations by operators.

[0024] In summary, the beneficial effects of the display module and display device provided in this application are as follows: Compared with the prior art, this application achieves flexible adjustment of the magnetic attraction force between two adjacent display modules by setting a slidable magnetic suction member on the connecting surface of the housing and using a driving member to drive the magnetic suction member to slide closer to or away from the connecting surface. When display modules need to be spliced, the driving member can be used to drive the magnetic suction member closer to the connecting surface to increase the magnetic attraction force and ensure a stable connection between the display modules; when display modules need to be disassembled, the driving member can be used to drive the magnetic suction member away from the connecting surface to reduce the magnetic attraction force and facilitate disassembly.

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

[0031] 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. Therefore, features defined as "first" or "second" may explicitly or implicitly include one or more features. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0032] This application provides a display device including multiple display modules, which can be arranged in a rectangular array. Adjacent display modules can be connected to each other by fasteners 330 such as screws 240, so that the multiple display modules together form a larger display screen.

[0033] Reference Figure 1 The display module includes a housing 100, a magnetic clasp 200, and a driving component 300. The housing 100 has at least one connecting surface for connecting another display module. The magnetic clasp 200 is disposed at the connecting surface and slidably connected to the housing 100. The magnetic clasp 200 is used to magnetically attract another display module connected to the connecting surface. The driving component 300 is connected to the magnetic clasp 200 and is used to drive the magnetic clasp 200 to slide towards or away from the connecting surface.

[0034] The cabinet 100 can be made of various materials, such as metal, plastic, or composite materials, and its internal space is configured to accommodate necessary components such as display panels and control circuits. One side surface of the cabinet 100 can serve as a display surface for displaying image content. The cabinet 100 is provided with at least one connecting surface, which is the interface for physical docking of the display modules with other display modules. For example, the connecting surface can be a flat sidewall or an edge with a specific shape, so that multiple display modules can be tightly spliced ​​together to form a continuous display screen. Optionally, the connecting surface is located on the peripheral side of the cabinet 100 and is distributed along the circumference of the cabinet 100 to achieve multi-directional module connection. The connecting surface can be provided with positioning structures, such as positioning holes or positioning posts, to achieve quick alignment when adjacent display modules are spliced. The connecting surface can also be provided with locking structures, such as snap-fit ​​or threaded holes 2142, to achieve a firm connection between two adjacent display modules using screws 240 or snap-fit ​​structures, improving the overall structural stability.

[0035] A magnetic suction element 200 is provided on or near the connecting surface of the housing 100. The magnetic suction element 200 is configured to slide with the housing 100. For example, the magnetic suction element 200 can be connected to the housing 100 through a guide rail structure, a sliding groove structure, or other mechanical sliding mechanism, allowing it to move relative to the housing 100 within a certain range. Optionally, a mounting cavity 101 can be provided at the connecting surface of the housing 100, and the magnetic suction element 200 is slidably connected within the mounting cavity 101. The mounting cavity 101 is a specific space formed inside the housing 100 to accommodate and guide the movement of the magnetic suction element 200. The mounting cavity 101 can be a channel penetrating the interior of the housing 100 or a groove created inside the housing 100.

[0036] The magnetic chuck 200 is slidably connected within the mounting cavity 101, allowing it to move along the cavity. The magnetic chuck 200 is used to magnetically attract another display module connected to its connecting surface. When the connecting surfaces of the two display modules approach each other, the magnetic chuck 200 generates sufficient magnetic force to firmly attract adjacent display modules together, thus achieving quick and reliable splicing and fixing between modules. The magnetic chuck 200 can be a single component or an assembly integrating magnets, with its magnetic force directed towards the connecting surface.

[0037] Combination Figure 2 As shown, in some embodiments, the magnetic attractor 200 may include a housing 210, a magnet 220, and a cover plate 230. The housing 210 is slidably connected within the mounting cavity 101, the driving member 300 is connected to the housing 210, and the housing 210 has a receiving cavity 211; the magnet 220 is disposed within the receiving cavity 211. The cover plate 230 is disposed on the housing 210 and closes the opening of the receiving cavity 211.

[0038] Specifically, the housing 210 is the main structure of the magnetic attractor 200, providing a protected mounting space for the magnet 220 and serving as a carrier for sliding connection with the mounting cavity 101 of the housing 100 and connection with the drive component 300. The housing 210 can be made of various materials, such as high-strength plastics, aluminum alloys, or stainless steel, to meet requirements for structural strength and corrosion resistance. The external shape of the housing 210 should match the shape of the inner wall of the mounting cavity 101 to ensure smooth sliding within the cavity.

[0039] Magnet 220 is the core component of the magnetic attractor 200, generating magnetic attraction to achieve a reliable connection between display modules. Magnet 220 can be made of permanent magnet material, such as neodymium iron boron magnet 220 or ferrite magnet 220, to provide a durable and stable magnetic force. The magnetic strength and magnetic field distribution of magnet 220 can be selected and optimized according to the connection requirements of the display modules. Magnet 220 can exist as a single large magnet 220, or it can be composed of multiple small magnets 220 arranged together to achieve the desired magnetic attraction effect.

[0040] The cover plate 230 serves to seal the opening of the receiving cavity 211, thereby completely encapsulating the magnet 220 within the housing 210 and providing it with physical protection. The cover plate 230 can be made of non-magnetic materials, such as engineering plastics, glass fiber reinforced plastics, or thin metal sheets, to avoid interfering with the magnetic field of the magnet 220. Various connection methods can be used between the cover plate 230 and the housing 210, such as screw fixing 240, snap-fit ​​connection, ultrasonic welding, or bonding, to ensure a secure connection that is not easily detached. The outer surface of the cover plate 230 is typically designed to be flat or slightly curved to provide a good contact surface when connected to other display modules.

[0041] By specifically designing the magnetic chuck 200 as a structure including a housing 210, a magnet 220, and a cover plate 230, wherein the housing 210 is slidably connected within the mounting cavity 101 and connected to the drive component 300, and the housing 210 has an internal receiving cavity 211 for placing the magnet 220, and the cover plate 230 closes the opening of the receiving cavity 211, the magnetic component (magnet 220) is effectively integrated, fixed, and protected. This structure allows the magnet 220 to remain stable during the sliding process of the magnetic chuck 200, avoiding wear, damage, or magnetic attenuation that may occur if the magnet 220 is directly exposed. At the same time, it also facilitates the assembly, replacement, and maintenance of the magnet 220, improving the reliability and service life of the display module.

[0042] In some embodiments, the cover plate 230 may be provided with a mounting hole 231, the magnet 220 may be provided with a clearance hole 221, and the housing 210 may be provided with a screw hole 212; the display module includes a screw 240, which passes through the mounting hole 231 and the clearance hole 221 and is threaded into the screw hole 212.

[0043] Specifically, mounting hole 231 is a through hole provided on cover plate 230, which provides a passage for fastener 330 to pass through. Mounting hole 231 can be designed as a countersunk hole or a flat hole depending on the head shape of fastener 330, ensuring that the head of fastener 330 is flush with or slightly below the surface of cover plate 230, thus preventing protrusions from affecting the overall structure or the fit with other components. Clearance hole 221 is a through hole provided inside magnet 220, which allows fastener 330 to pass through the magnet 220 body. The size and position of clearance hole 221 should be aligned with mounting hole 231 on cover plate 230 and screw hole 212 on housing 210 to ensure that fastener 330 can pass through smoothly and achieve connection. Clearance hole 221 of magnet 220 can be integrally formed during magnet 220 manufacturing or formed through subsequent processing. Screw hole 212 is an internal threaded hole 2142 provided on housing 210, which forms a threaded connection with fastener 330. The thread specification of screw hole 212 should match that of the selected screw 240 to ensure a strong and reliable connection.

[0044] The screw hole 212 can be pre-machined on the housing 210, or threads can be directly formed on the housing 210 using a self-tapping screw 240. The screw 240 is a threaded fastener 330 used to secure the cover plate 230, magnet 220, and housing 210 together via a threaded connection. The material and strength of the screw 240 should be sufficient to withstand the forces that the magnetic attractor 200 may experience during sliding and magnetic attraction, ensuring the stability of the connection. The screw 240 first passes through the mounting hole 231 on the cover plate 230, then continues through the clearance hole 221 inside the magnet 220, and finally engages with the screw hole 212 on the housing 210. In this way, the screw 240 tightly secures the cover plate 230 and magnet 220 together to the housing 210, forming a single unit.

[0045] Through the above technical solution, mounting holes 231 are provided on the cover plate 230, clearance holes 221 are provided on the magnet 220, and screw holes 212 are provided on the housing 210. Screws 240 are threaded into the screw holes 212 after passing through the mounting holes 231 and clearance holes 221 in sequence. This application provides a reliable fixing structure. The structure effectively and firmly fixes the magnet 220 within the receiving cavity 211 of the housing 210, preventing the magnet 220 from shifting or falling off due to vibration, impact, or sliding during the transportation, installation, or use of the display module. Simultaneously, the cover plate 230 is tightly connected to the housing 210 via screws 240, ensuring the sealing of the receiving cavity 211 and preventing the magnet 220 from being exposed or accidentally detached. This threaded connection method not only provides stable mechanical fixing but also facilitates the assembly and disassembly of the magnetic component 200, making maintenance and replacement easier, thereby significantly improving the overall structural stability and reliability of the magnetic component 200.

[0046] In some embodiments, the inner wall surface of the mounting cavity 101 is provided with at least one first guide structure, and the outer wall surface of the housing 210 is provided with at least one second guide structure, wherein the first guide structure and the second guide structure are slidably engaged.

[0047] Specifically, the inner wall of the mounting cavity 101 is provided with at least one first guide structure. The first guide structure is designed to provide a precise sliding trajectory for the housing 210 of the magnetic attractor 200. For example, the first guide structure can be embodied in the form of a guide groove 102, a guide protrusion 213, a guide rod, or a guide surface extending along the sliding direction of the magnetic attractor 200 on the inner wall of the mounting cavity 101. Its function is to restrict the lateral and rotational degrees of freedom of the housing 210 during the sliding process, ensuring that it moves smoothly along a preset direction. The second guide structure corresponds to the first guide structure and is used to cooperate with the first guide structure. For example, the second guide structure can be embodied in the form of a guide protrusion 213, a guide groove 102, a guide hole, or a guide block matching the first guide structure on the outer wall of the housing 210. Its function is to work in conjunction with the first guide structure to jointly form a stable guiding system.

[0048] Optionally, the first guiding structure may include multiple guide grooves 102 disposed on the inner wall of the mounting cavity 101, the extending direction of the guide grooves 102 being perpendicular to the connecting surface; the second guiding structure may include multiple guide protrusions 213 protruding from the peripheral sidewall of the housing 210, the extending direction of the guide protrusions 213 being perpendicular to the connecting surface, and each guide protrusion 213 being slidably embedded in each guide groove 102. The guide groove 102 is a recessed structure disposed on the inner wall of the mounting cavity 101, and the shapes of the guide protrusions 213 and the guide groove 102 should match each other. For example, when the guide groove 102 is a rectangular groove, the guide protrusion 213 can be a rectangular protrusion. The extending direction of the guide protrusion 213 is also perpendicular to the connecting surface, ensuring that its engagement with the guide groove 102 can guide the magnetic attractor 200 to perform linear movement. When the guide protrusion 213 is slidably embedded in the guide groove 102, a tight fit is formed between the two, so that when the magnetic suction member 200 slides under the action of the driving member 300, it can move smoothly along the preset trajectory and avoid lateral displacement.

[0049] In some embodiments, the housing 210 is provided with a limiting groove 2141, and the box 100 is provided with a limiting member 500. At least a portion of the limiting member 500 protrudes from the inner wall of the mounting cavity 101 and is slidably embedded in the limiting groove 2141 to limit the sliding distance of the magnetic member 200 in the mounting cavity 101.

[0050] Specifically, the limiting groove 2141 is a recessed structure provided on the housing 210 of the magnetic chuck 200. The groove can be a straight groove extending along the sliding direction of the magnetic chuck 200, or it can be a groove of other shapes designed according to specific needs. The limiting member 500 is a protruding structure or adjustable component provided on the housing 100. The limiting member 500 can be a fixing pin, a bolt, a protrusion, or any structure that can cooperate with the limiting groove 2141. A part of the limiting member 500 extends inward from the inner wall of the mounting cavity 101 and inserts into the limiting groove 2141 on the housing 210. When the magnetic chuck 200 slides in the mounting cavity 101, the limiting groove 2141 slides along the limiting member 500. This sliding engagement relationship ensures that the magnetic chuck 200 is always guided and constrained by the limiting member 500 during the sliding process, preventing the magnetic chuck 200 from completely dislodging from the mounting cavity 101.

[0051] Optionally, the limiting member 500 is a limiting bolt. The housing 100 has a mating hole 215, and the limiting bolt is threaded into the mating hole 215, with a portion of the limiting bolt extending into the mounting cavity 101 and embedded in the limiting groove 2141. The mating hole 215 is a through hole or blind hole provided on the housing 100, and its inner wall is usually machined with threads to match the threads of the limiting bolt. The limiting bolt is connected by its external thread engaging with the internal thread of the mating hole 215. This threaded connection method allows the limiting bolt to be easily screwed into or out of the mating hole 215, facilitating the assembly and disassembly of the magnetic component 200 and the limiting bolt. After the limiting bolt is screwed out of the mating hole 215, the magnetic component 200 can be easily removed from the mounting cavity 101 for maintenance or replacement.

[0052] The driving component 300 connects to the magnetic component 200 and drives the magnetic component 200 to slide within the mounting cavity 101 in a preset direction. For example, the driving component 300 can be connected to the magnetic component 200 via mechanical transmission methods such as linkages, gears, or cams, or via hydraulic or pneumatic methods. The driving component 300 drives the magnetic component 200 to slide towards or away from the connecting surface. Through the operation of the driving component 300, the magnetic component 200 can be pushed towards the connecting surface to enhance the magnetic attraction with adjacent modules; or it can be pulled away from the connecting surface to weaken or release the magnetic attraction, thereby facilitating the disassembly of the display module. When it is necessary to disassemble the display module, the driving component 300 can drive the magnetic component 200 away from the connecting surface, effectively weakening or releasing the magnetic attraction, avoiding the disassembly difficulties and potential damage to the module caused by excessive magnetic force in traditional solutions. As a result, the installation and disassembly process of the display module becomes more convenient and safer, improving operational efficiency and reducing maintenance costs. Furthermore, by weakening the magnetic attraction force in this embodiment, the adsorption strength of the magnetic component 200 on adjacent modules can be reduced, and the display module will not be accidentally detached due to the complete disappearance of the magnetic attraction force, thus ensuring safety during the disassembly process.

[0053] In some embodiments, the drive member 300 may be threadedly connected to the magnetic member 200 to drive the magnetic member 200 to slide when the drive member 300 rotates. That is, one of the drive member 300 and the magnetic member 200 has an external thread, and the other has an internal thread. For example, the drive member 300 may be designed as a screw with an external thread, while the magnetic member 200 (or its housing 210) is provided with an internally threaded hole 2142 that mates with the screw; or, the magnetic member 200 may have a protruding connecting post 214 with an external thread, while the drive member 300 is provided with an internal thread that mates with the connecting post 214. When a rotational force is applied to the drive member 300, due to the threaded engagement between it and the magnetic member 200, the rotational motion of the drive member 300 can be precisely converted into the linear reciprocating motion of the magnetic member 200, causing it to slide in a direction closer to or away from the connecting surface.

[0054] Optionally, the drive component 300 may include a drive sleeve 310 and a drive handle 320 connected to the drive sleeve 310. The drive sleeve 310 is provided with internal threads, and the drive handle 320 extends radially along the drive sleeve 310. The housing 210 may be provided with a connecting post 214 protrudingly. The housing 100 is provided with a connecting hole 103. The connecting post 214 is slidably inserted into the connecting hole 103, and at least a portion of the connecting post 214 is located outside the mounting cavity 101. The portion of the connecting post 214 located outside the mounting cavity 101 has external threads, and the drive sleeve 310 is threadedly connected to the connecting post 214.

[0055] The drive sleeve 310 is a hollow cylindrical structure with internal threads, and its axial length is adapted to the sliding stroke of the connecting column 214. The drive handle 320 is connected to the drive sleeve 310 and extends radially along the drive sleeve 310. The drive handle 320 provides a user-friendly interface for gripping and applying force, allowing the user to manually rotate the drive sleeve 310 to rotate it. The drive handle 320 can be integrally formed with the drive sleeve 310, or it can be fixed to the drive sleeve 310 by welding, screwing, or pinning. Its radially extended design increases the lever arm, allowing the user to easily rotate the drive sleeve 310 with a small torque, thereby driving the magnetic component 200. The drive handle 320 can have various shapes, such as rod-shaped, T-shaped, or knob-shaped.

[0056] The connecting post 214 can be a cylindrical structure. It can be integrally formed onto the housing 210, or fixed to the housing 210 by welding, screwing, or other methods. The connecting hole 103 is a through hole penetrating the wall of the housing 100. Its size and shape match the connecting post 214, allowing the connecting post 214 to slide freely axially within it while restricting its radial oscillation. A portion of the connecting post 214 passes through the connecting hole 103 on the housing 100 and extends to the outside of the display module for connection and operation with the external drive unit 300. The portion of the connecting post 214 located outside the mounting cavity 101 has external threads. These external threads match the internal threads of the drive sleeve 310, forming a threaded pair. When the drive sleeve 310 rotates, the housing 210 and the connecting post 214 are limited by the guide groove 102 and the guide post and cannot rotate. This causes the rotational motion of the drive sleeve 310 to be converted into the linear motion of the connecting post 214, thereby driving the magnetic suction member 200 to slide in the mounting cavity 101.

[0057] Furthermore, the drive component 300 may be provided with a bolt hole 321, the magnetic component 200 may be provided with a threaded hole 2142, and the display module may also include a fastener 330, which is rotatably inserted into the bolt hole 321 and threadedly connected into the threaded hole 2142.

[0058] Specifically, the bolt hole 321 on the drive member 300 primarily serves to provide a passage for the fastener 330. The bolt hole 321 is typically designed as a smooth, round hole with an inner diameter slightly larger than the diameter of the shank of the fastener 330, ensuring that the fastener 330 can pass freely and allowing the drive member 300 to rotate around it. The bolt hole 321 should be aligned with the threaded hole 2142 on the magnetic member 200 to facilitate the installation of the fastener 330. Specifically, the threaded hole 2142 on the magnetic member 200 can be located at the end or inside the connecting post 214 of the magnetic member 200. The threaded hole 2142 is used for threaded connection with the threaded portion of the fastener 330, thereby securing the fastener 330 to the magnetic member 200. The size and pitch of the threaded hole 2142 should match the selected fastener 330 to ensure a secure connection. Fastener 330 is a mechanical component, typically a screw 240 or bolt, used to connect drive member 300 and magnetic member 200. Its structure includes a head and a threaded shank. The shank of fastener 330 is rotatably inserted into the bolt hole 321 of drive member 300, meaning that the head of fastener 330 or a shoulder thereon can abut against drive member 300, preventing axial disengagement of drive member 300 while allowing drive member 300 to rotate freely about the axis of fastener 330. The threaded shank of fastener 330 is threaded into the threaded hole 2142 of magnetic member 200, thereby securely fixing fastener 330 to magnetic member 200.

[0059] In some embodiments, the display module may further include an elastic element 400. The elastic element 400 is disposed between the magnetic member 200 and the housing 100, and is used to apply a restoring force to the magnetic member 200 toward the connecting surface when the driving member 300 drives the magnetic member 200 to move away from the connecting surface.

[0060] Specifically, the elastic element 400 can be a helical compression spring, a disc spring, a rubber pad, or an elastic washer, etc. The elastic element 400 is typically positioned between the side of the magnetic chuck 200 away from the connecting surface and the inner wall of the housing 100. For example, the elastic element 400 can be a helical spring, sleeved on the portion of the connecting post 214 located inside the mounting cavity 101, with one end abutting against the inner wall of the housing 100 and the other end abutting against the end face of the housing 210. When the driving member 300 rotates and drives the magnetic chuck 200 to move away from the connecting surface, the elastic element 400 is compressed or deformed, storing elastic potential energy. When the external force is removed or the driving member 300 moves in the opposite direction, the elastic element 400 releases energy, pushing the magnetic chuck 200 back towards the connecting surface, achieving automatic reset. This allows the magnetic clasp 200 to automatically or assistedly and quickly return to a position close to the connection surface after separation from another display module, preventing it from remaining far from the connection surface after separation. This improves the convenience and efficiency of module connection operations. Furthermore, the reset force provided by the elastic element 400 ensures that the magnetic clasp 200 maintains a certain preload in the connected state, enhancing the stability and reliability of the connection and reducing the risk of accidental separation due to vibration or external impact.

[0061] Reference Figure 1 When two adjacent display modules are connected, the connecting surfaces of the two housings 100 abut against each other, and the magnetic attractor 200 is magnetically connected to the adjacent display module. It can be understood that the magnetic attractor 200 can directly magnetically attract the connecting surface of another display module; that is, the housing 100 of the display module is made of a magnetically attractive metal material at least in the connecting surface portion, or a magnetically attractive metal sheet is provided on the connecting surface, allowing the magnetic attractor 200 to directly adhere to the connecting surface of the other display module, achieving a stable connection. Alternatively, the magnetic attractor 200 can also magnetically connect to a magnetic attractor 200 provided on another display module. This magnetic attractor can be a magnet 220 embedded inside the connecting surface, or a magnetic sheet fixed to the connecting surface. (Refer to...) Figure 1In some embodiments, another display module is also provided with a magnetic chuck 200, which includes a magnet 220, a cover plate 230, and screws 240. The magnet 220 is directly embedded in the mounting cavity 101 of the housing 100, and the cover plate 230 is fixed to the housing 100 by the screws 240, closing the opening of the mounting cavity 101 to enclose the magnet 220 within the mounting cavity 101. The magnetic poles of the two interconnected magnets 220 should correspond to each other, i.e., the N pole of one magnet 220 should face the S pole of the other magnet 220, thereby generating a strong magnetic attraction force to ensure that the two display modules can be tightly and securely connected together. During disassembly, a drive unit 300 is used to move the magnetic chuck 200 of one display module away from the connecting surface. After the magnetic chuck 200 has moved a certain distance, the magnetic attraction force between the two magnetic chucks 200 weakens, facilitating disassembly.

[0062] Reference Figure 2 In other embodiments, the magnetic clasp 200 on another display module can also be slidably connected within the mounting cavity 101 and driven to move by the drive component 300. During disassembly, the magnetic clasp 200s of both display modules can be driven to move away from their respective connection surfaces simultaneously, causing the magnetic attraction between them to rapidly decrease to a level where they can be separated, thereby achieving rapid disassembly.

[0063] Reference Figure 3 In other embodiments, when the magnetic clasps 200 on both display modules are movable, each display module may further include a rotating rod 600 and a transmission component 700. The rotating rod 600 is rotatably connected to the housing 100, and the transmission component 700 is connected between the rotating rod 600 and the driving component 300, enabling the driving rod and the driving component 300 to rotate synchronously. Furthermore, the rotating rod 600 is also used to connect with the rotating rod 600 of another display module. When the two display modules are docked, the two rotating rods 600 are synchronously connected through a coupling structure at their ends. Therefore, during disassembly, only the driving component 300 of either module needs to be driven to cause the magnetic clasps 200 of both modules to move synchronously in opposite directions via the transmission component 700, achieving linked unlocking.

[0064] The rotating rod 600 typically refers to a slender component capable of rotating around its axis, whose main function is to transmit rotational motion or torque. The rotating rod 600 can be a solid or hollow shaft, such as a metal rod or a composite material rod, and its cross-sectional shape can be circular, square, or polygonal to adapt to different connection and transmission requirements. The material of the rotating rod 600 should possess sufficient strength and rigidity to withstand the stress generated during rotation. The rotatable connection between the rotating rod 600 and the housing 100 allows the rotating rod 600 to rotate freely relative to the housing 100, for example, by rotatably connecting it to a pre-set hole in the housing 100.

[0065] A connecting structure 610 may be provided at the end of the rotating rod 600 on the connecting surface, for cooperating with the connecting structure 610 at the end of the adjacent rotating rod 600 to achieve synchronous rotation of the two. This connecting structure 610 can be a keyway, spline, cross tenon, or magnetic coupler to ensure effective transmission of rotational torque. After the two display modules are docked and locked together, the connecting structures 610 at the ends of the two rotating rods 600 automatically engage, forming a rigid connection. At this time, rotating the drive component 300 of either module will drive the rotating rod 600 on that side to rotate via the transmission component 700, and then transmit the rotational motion to the rotating rod 600 of the other module via the coupling structure, achieving synchronous retraction of the magnetic components 200 on both sides.

[0066] The transmission component 700 is a mechanical element used to transmit motion and force between two or more components. In this embodiment, the transmission component 700 can take various forms, such as gears, sprockets and chains, pulleys and belts, worm gears, universal joints, or couplings. For example, the transmission component 700 can be a gear set connected between the drive sleeve 310 and the rotating rod 600. The gear set can consist of two or more meshing gears. When the drive component 300 rotates, torque is transmitted to the rotating rod 600 through the meshing of the gears, thereby achieving the purpose of synchronous rotation of the drive components 300 on both sides.

[0067] 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.
