DETAILED DESCRIPTION

[0044] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application more clearly understood, this application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0045] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or indirectly connected to the other element. The embodiments and features in the embodiments of this application may be combined with each other unless there is a conflict. The present application will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

[0046] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0047] In the description of this application, unless otherwise specified, " / " indicates that the objects associated before and after are in an "or" relationship, for example, A / B can represent A or B; "and / or" in this application is merely a description of the association relationship of associated objects, indicating that three relationships may exist, for example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural.

[0048] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0049] As described in the background, in related art, a display module includes a display body and a power supply assembly, which is detachably mounted on the display body. To maintain the power supply assembly, the entire assembly must first be removed from the display body and then disassembled piece by piece. This maintenance method is cumbersome and inefficient.

[0050] Reference Figures 1 to 3In order to solve the above problems, according to one aspect of the present application, an embodiment of the present application provides a display module, which includes a power supply assembly 100 and a mounting assembly 200. The power supply assembly 100 includes an electrical component 110 and a protective cover 120. The mounting assembly 200 includes a mounting component 210; the electrical component 110 is arranged on the mounting component 210, and the protective cover 120 is detachably mounted on the mounting component 210 for covering the electrical component 110.

[0051] In an embodiment of the present application, the electrical component 110 is installed on the mounting member 210 and is any one of a switching element, a control element, a rectifier element, a filter element, a voltage stabilizing element or a protection element; the mounting member 210 is a mounting plate or a mounting rod; the protective cover 120 can be detachably connected to the mounting member 210 by means of screw connection, snap connection, plug-in connection or magnetic connection. When the protective cover 120 is installed to the mounting member 210, the protective cover 120 completely covers the electrical component 110.

[0052] The detachable design of the protective cover 120 eliminates the need to disassemble the entire power supply assembly 100 for maintenance. The electrical components 110 can be accessed by simply opening the protective cover 120, which reduces the number of disassembly steps, simplifies the maintenance process, and improves maintenance efficiency. Furthermore, the protective cover 120 also protects the electrical components 110.

[0053] In addition, in order to facilitate in-depth maintenance of the electrical component 110, the electrical component 110 can be detachably installed on the mounting component 210. Specifically, the electrical component 110 can be detachably installed on the mounting component 210 by plugging or screw connection.

[0054] Reference Figures 1 to 5 In one embodiment, the protective cover 120 is provided with a first magnetic structure 121, and the mounting member 210 is provided with a second magnetic structure 211. The protective cover 120 is detachably mounted on the mounting member 210 through the first magnetic structure 121 and the second magnetic structure 211 that are magnetically attracted to each other.

[0055] In this embodiment, the first magnetic structure 121 is a magnetic column, which is installed in the mounting hole of the protective cover 120 by means of threaded fit or interference fit; the second magnetic structure 211 is a magnetic block, which is installed on the mounting part 210 by means of gluing or welding.

[0056] The magnetic connection can be quickly installed and separated without the use of tools. This connection method not only helps to shorten maintenance time and improve the convenience of maintenance operations; it also provides reliable connection force to ensure the protection effect of electrical components 110.

[0057] Reference Figure 1 and Figure 2In one embodiment, there are multiple electrical components 110, and the multiple electrical components 110 are spaced apart along a first direction, and the first direction is parallel to the length direction of the mounting member 210. It is understood that the first direction can also be parallel to the width direction or thickness direction of the mounting member 210.

[0058] The structural design of multiple electrical components 110 arranged at intervals along the first direction not only conforms to the modular layout, but also makes full use of the planar space of the mounting member 210 through regular arrangement, effectively reducing the longitudinal dimension of the power supply assembly 100, making the overall thickness of the power supply assembly 100 thinner, and achieving a compact and orderly structure of the power supply assembly 100. At the same time, it also increases the air circulation space, reduces heat accumulation, and improves the heat dissipation efficiency. In addition, it also makes the layout of the multiple electrical components 110 clear, facilitates the rapid location of faulty components during maintenance, and improves the convenience of maintenance. In addition, the interval setting also effectively reduces the electromagnetic interference between adjacent electrical components 110 and improves the working stability of the power supply assembly 100.

[0059] Reference Figure 1 and Figure 2 In one embodiment, the power supply assembly 100 further includes two electrical connectors 130 , which are spaced apart along the first direction on the mounting member 210 , and a plurality of electrical components 110 are disposed between the two electrical connectors 130 and electrically connected to the electrical connectors 130 .

[0060] In this embodiment, the electrical connector 130 is a power plug, and the electrical connector 130 is fixed to the mounting member 210 by means of connecting screws; the plurality of electrical components 110 are electrically connected to the electrical connectors 130 to be connected.

[0061] Multiple electrical components 110 are concentrated between two electrical connectors 130, shortening internal wiring lengths, reducing cross-wiring, and improving layout neatness and reliability. Electrical connectors 130 also serve as independent interfaces, facilitating docking between the power supply assembly 100 and external devices. Furthermore, electrical connectors 130 are spaced apart and positioned close to the electrical components 110, reducing signal transmission losses and improving the power and signal transmission efficiency of the power supply assembly 100. Furthermore, the clear positional relationship between electrical connectors 130 and electrical components 110 facilitates quick identification of faulty components during troubleshooting.

[0062] Reference Figure 3 and Figure 4In one embodiment, the protective cover 120 has a first protective surface 122 and a second protective surface 123, the second protective surface 123 is arranged opposite to the first protective surface 122 along a second direction, and the second direction is perpendicular to the first direction; the first protective surface 122 is provided with a plurality of first heat dissipation holes 1221 and / or a plurality of first heat dissipation ribs 1222, and the second protective surface 123 is provided with a plurality of second heat dissipation holes 1231 and / or a plurality of second heat dissipation ribs 1232.

[0063] In this embodiment, the protective cover 120 is made of aviation-grade magnesium alloy. The first protective surface 122 and the second protective surface 123 are both outer surfaces of the protective cover 120. A first heat dissipation rib 1222 is arranged to protrude outwardly away from the interior of the protective cover 120. Multiple first heat dissipation ribs 1222 are spaced apart along the first direction and are integrally formed with the protective cover 120. A first heat dissipation hole 1221 is located between two adjacent first heat dissipation ribs 1222 and is a through hole that penetrates the protective cover 120. Multiple first heat dissipation holes 1221 are spaced apart. A second heat dissipation rib 1232 is arranged to protrude outwardly away from the interior of the protective cover 120. Multiple second heat dissipation ribs 1232 are spaced apart along the first direction and are integrally formed with the protective cover 120. A second heat dissipation hole 1231 is located between two adjacent second heat dissipation ribs 1232 and is a through hole that penetrates the protective cover 120. Multiple second heat dissipation holes 1231 are spaced apart. It is understandable that the first protection surface 122 may be provided with only the first heat dissipation holes 1221 or the first heat dissipation ribs 1222 , and the second protection surface 123 may be provided with only the second heat dissipation holes 1231 or the second heat dissipation ribs 1232 .

[0064] The first protective surface 122 and the second protective surface 123 arranged opposite to each other along the second direction are respectively equipped with a first heat dissipation hole 1221 and a second heat dissipation hole 1231, forming a three-dimensional heat dissipation channel perpendicular to the arrangement direction of the electrical components 110, accelerating heat exchange through air convection and improving heat dissipation efficiency.

[0065] The first and second heat dissipation ribs 1222 and 1232 not only increase the surface area of the protective cover 120, enhancing its thermal conductivity, but also form a synergistic heat dissipation mechanism of "heat conduction + convection" with the first and second heat dissipation holes 1221 and 1231, effectively reducing the temperature of the electrical components 110 within the protective cover 120. Furthermore, the first and second heat dissipation holes 1221 and 1231 are concealed, improving the dustproofing of the protective cover 120 while ensuring effective heat dissipation. Furthermore, the structural strength of the protective cover 120 is enhanced.

[0066] Reference Figure 2 and Figure 6In one embodiment, the protective cover 120 further has a third protective surface 124, which is adjacent to the first protective surface 122 and adjacent to the second protective surface 123, and the third protective surface 124 is provided with a plurality of third heat dissipation holes 1241 and / or a plurality of third heat dissipation ribs 1242.

[0067] In this embodiment, the protective cover 120 is shaped like a rectangular parallelepiped, and the third protective surface 124 is the outer top surface of the protective cover 120. Third heat dissipation ribs 1242 are arranged to protrude outwardly, facing away from the interior of the protective cover 120. The length of the third heat dissipation ribs 1242 is parallel to the first direction. Multiple third heat dissipation elements are arranged at intervals along a direction perpendicular to the first and second directions and are integrally formed with the protective cover 120. Third heat dissipation holes 1241 are located between adjacent third heat dissipation ribs 1242 and are through-holes that penetrate the protective cover 120. Multiple third heat dissipation holes 1241 are spaced apart.

[0068] The third protective surface 124, equipped with third heat dissipation holes 1241, cooperates with the first protective surface 122 and the second protective surface 123 to form a three-dimensional heat dissipation channel, eliminating heat dissipation blind spots and further improving heat dissipation efficiency. The third heat dissipation holes 1241, used in conjunction with the first heat dissipation holes 1221 and / or the second heat dissipation holes 1231, can guide air to form cross convection, effectively enhancing heat exchange efficiency. Furthermore, the third heat dissipation ribs 1242 can not only conceal the third heat dissipation holes 1241, further improving the dustproof effect of the protective cover 120, but also further enhance the thermal conductivity and structural strength of the protective cover 120.

[0069] Reference Figure 2 and Figure 6 In one embodiment, the protective cover 120 is provided with a connecting screw 140, and the mounting member 210 is provided with a connecting hole 522, and the connecting screw 140 is threadedly engaged with the hole wall of the connecting hole 522; the connecting screw 140 has a limiting handle 141, and when the connecting screw 140 is screwed into the connecting hole 522, the limiting handle 141 limits the rotation of the connecting screw 140 relative to the protective cover 120 by hooking on the protective cover 120.

[0070] In this embodiment, the connecting screw 140 is a captive screw; however, it is understood that the connecting screw 140 may also be an ordinary screw. The connecting hole 522 is a threaded hole, and the connecting screw 140 is detachably connected to the mounting member 210 by threaded engagement with the wall of the connecting hole 522. A limit handle 141 is rotatably disposed on the connecting screw 140. When the connecting screw 140 is connected to the mounting member 210, the limit handle 141 hooks onto the outer surface of the protective cover 120 to limit the rotation of the connecting screw 140 relative to the protective cover 120.

[0071] The provision of connecting screw 140 further strengthens the connection between protective cover 120 and mounting member 210. Furthermore, as a captive screw, connecting screw 140 offers advantages such as quick screwing and securement, and prevents loss. Protective cover 120 and mounting member 210 can be connected and disconnected without complete disassembly, improving maintenance efficiency. Furthermore, a limit handle 141, by hooking onto protective cover 120, restricts the rotation of connecting screw 140, effectively reducing the risk of loosening and falling out due to factors such as vibration, thereby ensuring a reliable connection.

[0072] In addition, to strengthen the connection strength between the protective cover 120 and the mounting member 210, the number of connecting screws 140 is two, and the two connecting screws 140 are spaced apart along the second direction. At the same time, the number of first magnetic structures 121 is four, and the four first magnetic structures 121 are respectively arranged at the four corners of the protective cover 120. The number of second magnetic structures 211 is the same as the number of first magnetic structures 121, and the multiple second magnetic structures 211 are respectively arranged in a one-to-one correspondence with the multiple first magnetic structures 121. It is understandable that the number of connecting screws 140, first magnetic structures 121, and second magnetic structures 211 can also be other numbers, depending on actual needs.

[0073] In addition, in order to facilitate the separation of the protective cover 120 from the mounting member 210 , both the first protective surface 122 and the second protective surface 123 of the protective cover 120 are provided with a pulling handle 125 .

[0074] Reference Figure 5 In one embodiment, a mounting groove 212 is provided on the surface of the mounting member 210 close to the protective cover 120 , and the electrical member 110 is disposed in the mounting groove 212 .

[0075] In this embodiment, the mounting groove 212 is recessed, facing away from the protective cover 120. The electrical components 110 are embedded within the mounting groove 212, utilizing the three-dimensional space to achieve a modular layout. This reduces the longitudinal dimensions of the display module, making the overall thickness of the display module thinner and more compact. Furthermore, the mounting groove 212 physically limits the electrical components 110, preventing them from shifting during installation or in vibration environments, thereby enhancing their structural stability.

[0076] Reference Figure 1 and Figure 2 In one embodiment, the mounting assembly 200 further includes a mounting frame 220 , and the mounting member 210 is disposed on the mounting frame 220 .

[0077] In the embodiment of the present application, the mounting frame 220 is made of magnesium alloy. The mounting frame 220 is a square frame and includes four frame bars or frame rods connected end to end. The mounting member 210 is mounted on the mounting frame 220 .

[0078] By supporting the mounting member 210 and the power supply assembly 100 on the mounting frame 220, the overall weight of the display module is effectively reduced while ensuring the structural strength of the display module. Furthermore, the power supply assembly 100 is mounted on the mounting member 210, and the mounting member 210 is mounted on the mounting frame 220. This eliminates the need to disassemble the entire display module when maintaining the power module, reducing maintenance difficulty and cost while increasing ease of maintenance. Furthermore, if the mounting frame 220 is made of metal, it can also form a shielding structure, suppressing electromagnetic interference and improving the electromagnetic compatibility of the display module.

[0079] Reference Figure 1 and Figure 2 In one embodiment, the length direction of the mounting frame 220 is parallel to the first direction, and the first direction is parallel to the length direction of the mounting member 210 .

[0080] In this embodiment, the centerline of the mounting member 210 along its length coincides with the centerline of the mounting frame 220 along its length. This alignment of the lengths of the mounting member 210 and the mounting frame 220 not only aligns the mechanical transmission paths between the two in the first direction, avoiding stress concentration or eccentric loading caused by directional misalignment, but also ensures the stability of the connection between the mounting member 210 and the mounting frame 220. It also facilitates the routing of cables, pipes, and the like in the first direction, avoiding cross-contamination and improving internal space utilization and cleanliness.

[0081] Reference Figure 1 and Figure 2 In one embodiment, the mounting assembly 200 further includes a reinforcement member 230 , which is disposed on the mounting frame 220 , and a length direction of the reinforcement member 230 is perpendicular to a length direction of the mounting member 210 .

[0082] In this embodiment, the reinforcement 230 is a reinforcement plate or a reinforcement rod, which is installed on the mounting frame 220 , and the center line of the reinforcement 230 along the length direction coincides with the center line of the mounting frame 220 along the width direction.

[0083] The reinforcement 230 is arranged perpendicularly to the mounting member 210 to form a cross-shaped or grid-shaped support structure, which can disperse stress in different directions (such as lateral and longitudinal loads) and improve the deformation resistance of the mounting assembly 200. At the same time, the vertically arranged reinforcement 230 can guide external impact or vibration to be transmitted in an orthogonal direction, avoiding stress concentration on a single component and reducing the risk of damage to the mounting assembly 200 or the power supply assembly 100. In addition, the orthogonal structural design can achieve multi-dimensional support with less material, improving the overall rigidity without significantly increasing the overall weight, which is suitable for lightweight design requirements.

[0084] Reference Figure 1 、 Figure 2 as well as Figures 7 to 9 In one embodiment, the display module further includes a display component 300, which includes a plurality of display elements 310 arranged in sequence along a first direction, wherein the first direction is parallel to the length direction of the mounting frame 220; the display element 310 includes a plurality of light-emitting bodies 311, a plurality of driving bodies 312, and a carrier 313, wherein the plurality of light-emitting bodies 311 are arranged at intervals on the carrier 313, the number of driving bodies 312 is the same as the number of light-emitting bodies 311, and the plurality of driving bodies 312 are arranged at intervals on the carrier 313 and are electrically connected to the plurality of light-emitting bodies 311 in a one-to-one correspondence.

[0085] In this embodiment, the light-emitting body 311 includes multiple LED lamp beads. The full name of LED in English is Light Emitting Diode, and its Chinese name is Light Emitting Diode; the driver 312 is a driving circuit, abbreviated as driver IC, the full name of IC in English is Integrated Circuit, and its Chinese name is integrated circuit. There is a heat dissipation distance between adjacent drivers 312 and light-emitting bodies 311; the carrier 313 is a carrier board, and the light-emitting body 311 and the driver 312 are both installed on the carrier 313.

[0086] Multiple display elements 310 are arranged sequentially along a first direction, reducing the manufacturing difficulty and cost of display assembly 300 through a modular design. Furthermore, the parallel arrangement of mounting elements 210 and mounting frame 220 ensures that the power supply assembly 100 and display assembly 300 are aligned in the same direction, minimizing lateral cross-over and reducing the overall size of the display module, resulting in a compact and organized display module structure.

[0087] The light-emitting body 311 and the driver 312 are spaced apart on the carrier 313 , which helps the light-emitting body 311 and the driver 312 to dissipate heat, avoids the concentration of heat sources, reduces the possibility of the display element 310 heating up and turning blue due to the concentrated distribution of the light-emitting body 311 and the driver 312 , and improves the display effect of the display element 310 .

[0088] In addition, the driver 312 corresponds one-to-one with the light-emitting body 311 , which helps to accurately control each light-emitting body 311 , thereby improving the brightness uniformity and color accuracy of the display element 310 .

[0089] Reference Figure 2 、 Figure 5 as well as Figures 7 to 10 In one embodiment, the display module further includes a shading assembly 400, which covers the display assembly 300; the shading assembly 400 includes a plurality of shading plates 410 and a plurality of stoppers 420, wherein the plurality of shading plates 410 are spaced apart and located inside the mounting frame 220, and each shading plate 410 is correspondingly provided with at least one stopper 420; the stopper 420 is located on a side of the shading plate 410 away from the display assembly 300, and is detachably mounted on the mounting frame 220, and is used to prevent the shading plate 410 from moving in a direction away from the display assembly 300 by contacting the shading plate 410.

[0090] In this embodiment, the shading assembly 400 completely covers the display assembly 300, and the shading plate 410 is completely located within the mounting frame 220. A plurality of stoppers 420 are provided corresponding to each shading plate 410, and the plurality of stoppers 420 are spaced apart. The stoppers 420 include a mounting structure 421, a connecting structure 422, and a stopper structure 423. The mounting structure 421 is an L-shaped mounting plate, and the connecting structure 422 is a captive screw. The mounting structure 421 is detachably mounted on the mounting frame 220 or the mounting member 210 via the connecting structure 422. The stopper structure 423 is a stopper screw and is mounted on the mounting structure 421. To ensure a stopping effect, the stopper 420 includes multiple stopper structures 423.

[0091] In a specific embodiment, the number of the display elements 310 is eight, the number of the light shielding plates 410 is four, and the four light shielding plates 410 are respectively provided in one-to-one correspondence with the four corners of the mounting frame 220 .

[0092] The shading assembly 400 covers the display assembly 300, effectively blocking light leakage from the adjacent display element 310 and improving the contrast and color purity of the display module's image. The shading panels are designed to be multiple, independent pieces, which not only reduces the manufacturing difficulty and cost of the shading assembly 400 but also allows for the independent removal and replacement of a single faulty shading panel 410 without disassembling the entire shading assembly 400, reducing maintenance costs.

[0093] Furthermore, the baffle plate, positioned within the mounting frame 220, not only effectively protects the shading plate 410 but also reduces the overall thickness of the display module. Furthermore, the stopper 420 is removably secured to the mounting frame 220. This precisely defines the position of the shading plate 410 through physical contact, preventing shifting and resulting shading failure. It also allows for quick assembly and disassembly, facilitating positional alignment during production and assembly, as well as subsequent maintenance.

[0094] Reference Figures 1 to 15 According to another aspect of the present application, an embodiment of the present application provides a display device, which includes multiple connection modules and multiple display modules mentioned above. The number of connection modules is the same as the number of display modules, and the multiple connection modules are respectively arranged in a one-to-one correspondence with the multiple display modules.

[0095] The connecting module includes a first connecting component, which includes a first connecting member 510 and a second connecting member 520. The first connecting member 510 and the second connecting member 520 are arranged at intervals on the mounting frame 220 along a first direction, and the first direction is parallel to the length direction of the mounting frame 220; the first connecting member 510 includes a connecting body 511, and the connecting body 511 can rotate relative to the mounting frame 220; the second connecting member 520 is provided with a connecting groove 521, and the extension direction of the connecting groove 521 is perpendicular to the first direction; two display modules arranged in sequence along the first direction are connected by rotating the connecting body 511 and inserting it into the connecting groove 521.

[0096] In the embodiment of the present application, the connector 511 is a connecting pin, and the connecting groove 521 can be provided inside the second connecting member 520 or on the outer surface of the second connecting member 520. In addition, when two display modules arranged sequentially along the first direction are connected, the surfaces of the two display modules that are close to each other remain in contact.

[0097] By rotating the connector 511 into the connecting groove 521, not only can two display modules arranged sequentially along the first direction be quickly joined, but this also reduces the difficulty of assembling two adjacent display modules and improves assembly efficiency. Furthermore, the connecting groove 521 extends perpendicular to the first direction. This structural design enhances the connection strength between two display modules arranged sequentially along the first direction and prevents relative displacement between adjacent display modules.

[0098] In addition, the two connected display modules can be quickly separated by rotating the connector 511, which facilitates independent repair or replacement of a single display module, reducing maintenance difficulty and cost.

[0099] Reference Figure 1 、 Figure 2 as well as Figures 11 to 15In one embodiment, the first connecting member 510 also includes a first connecting body 512, and the connecting body 511 is set on the first connecting body 512. The first connecting body 512 can drive the connecting body 511 to move along the first direction and can drive the connecting body 511 to rotate; the second connecting member 520 is provided with a connecting hole 522 along the first direction, and the connecting hole 522 is connected to the connecting groove 521; in the process of connecting two display modules arranged in sequence along the first direction, the first connecting body 512 drives the connecting body 511 to pass through the connecting hole 522, and then drives the connecting body 511 to rotate and insert into the connecting groove 521.

[0100] In this embodiment, the first connecting body 512 is a connecting rod 7113. The length of the first connecting body 512 of the first connecting member 510 is parallel to the first direction, and the connecting body 511 is fixedly mounted on the first connecting body 512. The connecting hole 522 is a through hole that penetrates the second connecting member 520, and both the first connecting body 512 and the connecting body 511 can pass through the connecting hole 522. The connecting groove 521 is provided on the outer surface of the second connecting member 520 and is located on the side of the connecting hole 522 that is away from the first connecting member 510 in the first direction.

[0101] The first connecting body 512 supports and mounts the connecting body 511, allowing operators to precisely control the movement and rotation of the connecting body 511, enhancing the convenience of connecting or disconnecting the display modules. The connecting hole 522, through its pre-positioning design, guides the insertion path of the connecting body 511, preventing collisions between the connecting body 511 and the connecting slot 521 or the connecting hole 522 due to blind rotation.

[0102] Reference Figure 1 、 Figure 2 as well as Figures 11 to 15 In one embodiment, the first connecting member 510 also includes a first mounting body 513, the first mounting body 513 is arranged on the mounting frame 220, the first connecting body 512 is slidably arranged on the first mounting body 513 along the first direction, and is rotatably arranged on the first mounting body 513; the first connecting member 510 also includes a first elastic body 514, and a limiting cap 5121 is provided at one end of the first connecting body 512 away from the connecting body 511. The first elastic body 514 is sleeved on the first connecting body 512 and is located between the limiting cap 5121 and the surface of the first mounting body 513 close to the limiting cap 5121, and is used to apply an elastic thrust to the limiting cap 5121 toward the end away from the first mounting body 513.

[0103] In this embodiment, the first mounting body 513 is a mounting block, and is detachably mounted on the mounting frame 220 by connecting screws; a mounting through hole is provided on the first mounting body 513, and the first connecting body 512 is slidably set in the mounting through hole along the first direction and rotatably set in the mounting through hole; the first elastic body 514 is a spring.

[0104] The first elastic body 514 applies an elastic thrust to the limiting cap 5121 of the first connecting body 512, causing the connecting body 511 to tend to move toward the connecting slot 521. For splicing, the operator only needs to align the adjacent display modules. Once the connecting body 511 contacts the connecting slot 521, the operator simply rotates it to trigger the automatic engagement, automatically inserting the connecting body 511 into the connecting slot 521. This eliminates the need for continuous manual force application and improves connection efficiency. For disassembly, the operator only needs to overcome the resistance generated by the compression of the first elastic body 514 to easily rotate and extract the connecting body 511 from the connecting slot 521, avoiding the problem of separation being impossible due to rigidity.

[0105] In addition, the first connecting member 510 further includes elastic beads, and the second connecting member 520 is provided with positioning grooves; when two display modules arranged in sequence along the first direction are connected, the elastic beads are inserted into the positioning grooves.

[0106] Reference Figure 1 、 Figure 2 as well as Figures 11 to 15 In one embodiment, the first connecting member 510 also includes a limiting sleeve 515, which is sleeved on the outer periphery of the first elastic body 514 along the first direction and is located on the side of the limiting cap 5121 close to the first mounting body 513. The limiting sleeve 515 is threadedly engaged with the first mounting body 513 to push the limiting cap 5121 to move in a direction away from the first mounting body 513.

[0107] In this embodiment, before the connector 511 is inserted into the connection slot 521, a predetermined distance is maintained between the limiting cap 5121 and the surface of the limiting sleeve 515 proximate to the limiting cap 5121 under the action of the first elastic body 514. During the insertion of the connector 511 into the connection slot 521, the limiting sleeve 515 is driven to rotate on the first mounting body 513, so that the limiting sleeve 515 moves toward the limiting cap 5121. During this process, the first elastic body 514 is gradually compressed. After the limiting sleeve 515 drives the limiting cap 5121 to move a predetermined distance, the connector 511 is rotated via the first connecting body 512. The connector 511 is automatically inserted into the connection slot 521 under the action of the elastic thrust exerted by the first elastic body 514. In addition, to facilitate the rotation of the limiting sleeve 515, the limiting sleeve 515 has a force-applying handle 516.

[0108] On the one hand, the limiting sleeve 515 can adjust the compression of the first elastic body 514 by threadedly cooperating with the first mounting body 513 , thereby changing the elastic thrust of the connecting body 511 .

[0109] On the other hand, the first elastic body 514 is first rotated and compressed by the limiting sleeve 515 (energy storage process), and then the connecting body 511 is rotated to trigger the release of the elastic thrust, so that the connecting body 511 is quickly inserted into the connecting groove 521, reducing the shaking during splicing and improving the connection accuracy and firmness.

[0110] On the other hand, the limiting sleeve 515 is threadedly engaged with the first mounting body 513, so that the first elastic body 514 can be removed from the first connecting body 512 for maintenance, providing convenience for maintenance.

[0111] Reference Figure 1 、 Figure 2 as well as Figures 11 to 15 In one embodiment, the second connecting member 520 is detachably mounted on the mounting frame 220 using connecting screws; at the same time, two limiting protrusions 523 are provided on the surface of the second connecting member 520 where the connecting groove 521 is provided. The two limiting protrusions 523 are respectively provided on opposite sides of the connecting groove 521 to prevent the connecting body 511 from continuously rotating along the same direction.

[0112] Reference Figure 1 、 Figure 2 as well as Figures 11 to 15 In one embodiment, in order to improve the connection strength of two display modules arranged sequentially along the first direction, the number of first connecting members 510 and second connecting members 520 is multiple, the number of second connecting members 520 is the same as the number of first connecting members 510, and the multiple second connecting members 520 are respectively arranged in a one-to-one correspondence with the multiple first connecting members 510.

[0113] Reference Figure 1 and Figure 2 In one embodiment, the first connecting component further includes a third connecting member 610 and a fourth connecting member 620, and the third connecting member 610 and the fourth connecting member 620 are spaced apart on the mounting frame 220 along the second direction, and the second direction is perpendicular to the first direction; the structure of the third connecting member 610 is the same as that of the first connecting member 510, and the structure of the fourth connecting member 620 is the same as that of the second connecting member 520; two display modules arranged in sequence along the second direction are connected by the cooperation of the third connecting member 610 and the fourth connecting member 620.

[0114] In this embodiment, the second direction is parallel to the width of the mounting frame 220. The coordinated connection between the third connector 610 and the fourth connector 620 not only allows for the rapid assembly of two display modules arranged sequentially along the second direction, but also reduces the difficulty and improves the efficiency of assembling two adjacent display modules. Furthermore, the third connector 610 reuses the structure of the first connector 510, and the fourth connector 620 reuses the structure of the second connector 520, reducing mold development costs and improving assembly efficiency.

[0115] Reference Figure 1 、 Figure 2 as well as Figures 16 to 27 In one embodiment, the connecting module includes a third connecting component, the third connecting component includes a fifth connecting member 710 and a sixth connecting member 720, and the fifth connecting member 710 and the sixth connecting member 720 are arranged on the mounting member 210 at intervals along the first direction; the fifth connecting member 710 includes a connecting hook 711, and the connecting hook 711 is rotatably set on the mounting member 210, and the two display modules arranged at intervals along the first direction are connected by hooking with the sixth connecting member 720 through the connecting hook 711.

[0116] In this embodiment, the connection hook 711 and the sixth connection member 720 can be coordinated in such a manner that the connection hook 711 hooks the edge of the sixth connection member 720, the connection hook 711 is inserted into the side of the boss on the sixth connection member 720, or the connection hook 711 is hooked on the rope or chain on the sixth connection member 720.

[0117] On the one hand, the third connecting component cooperates with the first connecting component to form a double connection, thereby avoiding the failure risk of a single connection and improving the connection strength of the two display modules arranged sequentially along the first direction.

[0118] On the other hand, the user only needs to complete simple actions such as pushing and snapping with one hand to achieve the hook connection between the connecting hook 711 of the fifth connecting member 710 and the sixth connecting member 720. Compared with the connection method of collaborative operation with both hands, this connection method not only reduces the operation difficulty, but also shortens the connection time of the fifth connecting member 710 and the sixth connecting member 720, thereby improving the connection efficiency.

[0119] On the other hand, the connecting hook 711 of the fifth connecting member 710 and the sixth connecting member 720 are firmly connected through a physical mechanical structure, which can effectively withstand tension and shear force, thereby enhancing the stability and reliability of the connection between the fifth connecting member 710 and the sixth connecting member 720.

[0120] Furthermore, the third connecting assembly has a detached state. When the third connecting assembly is in the detached state, the fifth connecting member 710 is disconnected from the sixth connecting member 720. To separate two display modules arranged sequentially along the first direction, simply disconnect the fifth connecting member 710 and the sixth connecting member 720, making the operation simple and quick. Furthermore, when the third connecting assembly is in the detached state, the fifth connecting member 710 and the sixth connecting member 720 can be individually removed for inspection or replacement, reducing overall maintenance costs and time.

[0121] Furthermore, two surfaces of the mounting member 210 that are positioned opposite each other along the first direction are respectively provided with a first magnetic block 7122 and a second magnetic block 7215. The first magnetic block 7122 and the second magnetic block 7215 are magnetically attracted to each other; when two display modules arranged sequentially along the first direction are connected, the first magnetic block 7122 and the second magnetic block 7215 are magnetically connected. Furthermore, two surfaces of the mounting member 210 that are positioned opposite each other along the first direction are respectively provided with elastic beads and positioning grooves. When two display modules arranged sequentially along the first direction are connected, the elastic beads are inserted into the positioning grooves.

[0122] Reference Figures 16 to 24 In one embodiment, the sixth connecting member 720 has a hooking groove 7212; when the third connecting assembly is in the connected state, the connecting hook 711 is hooked into the hooking groove 7212. In this embodiment, when the third connecting assembly is in the disconnected state, the connecting hook 711 is located outside the hooking groove 7212.

[0123] On the one hand, after the connecting hook 711 is hooked into the hooking groove 7212, a mechanical lock is formed, which can effectively limit the displacement of the fifth connecting member 710 and the sixth connecting member 720 in the hooking direction of the connecting hook 711, provide a stable connecting force, and effectively improve the stability and reliability of the connection between the fifth connecting member 710 and the sixth connecting member 720.

[0124] On the other hand, when the connecting hook 711 needs to be disengaged from the hooking slot 7212, a rotational force in a specific direction needs to be applied to the connecting hook 711, rather than a simple linear pulling force or pushing force, thereby reducing the risk of the connecting hook 711 being disengaged from the hooking slot 7212 due to accidental collision.

[0125] On the other hand, the hooking groove 7212 can also guide the connection hook 711 to enter, playing a guiding role and reducing the difficulty of connecting the fifth connecting member 710 and the sixth connecting member 720.

[0126] Reference Figures 16 to 24In one embodiment, the fifth connecting member 710 also includes a fifth connecting body 712 and a driving handle 713. The fifth connecting body 712 is set on the mounting member 210, the driving handle 713 is rotatably set on the fifth connecting body 712, and the connecting hook 711 is rotatably set on the driving handle 713; when the third connecting component is switched to the connection state, the driving handle 713 drives the connecting hook 711 to rotate toward the hooking groove 7212 along the first direction. After the connecting hook 711 is hooked into the hooking groove 7212, the driving handle 713 rotates along the second direction opposite to the first direction to reset.

[0127] In this embodiment, the fifth connecting body 712 serves as a connecting base and is fixedly mounted on the mounting member 210. A first rotating shaft 7121 is fixedly mounted on the fifth connecting body 712, and the driving handle 713 is rotatably mounted on the first rotating shaft 7121. It is understood that the first rotating shaft 7121 can also be rotatably mounted on the fifth connecting body 712, and the driving handle 713 is fixedly mounted on the first rotating shaft 7121. The connecting hook 711 is rotatably mounted on the driving handle 713 using a bearing. The rotation axis of the connecting hook 711 is parallel to, but not colinear with, the axis of the first rotating shaft 7121. After the connecting hook 711 is hooked into the hooking slot 7212, it is restrained by the hooking slot 7212 and cannot rotate. The driving handle 713 can be reset independently along the second rotation direction.

[0128] In addition, when the third connecting component is in a separated state, the angle between the driving handle 713 and the fifth connecting body 712 is zero, and the maximum angle between the connecting hook 711 and the fifth connecting body 712 is 52°; in the process of the third connecting component switching from a separated state to a connected state, the angle between the driving handle 713 and the fifth connecting body 712 gradually increases, and the angle between the connecting hook 711 and the fifth connecting body 712 gradually decreases, and the maximum angle between the driving handle 713 and the fifth connecting body 712 is 70°. At this time, the connecting hook 711 is in a state ready to hook into the hooking groove 7212.

[0129] When the fifth connecting member 710 and the sixth connecting member 720 need to be connected, the user rotates the driving handle 713 along the first direction, directly driving the connecting hook 711 to rotate and hook into the hook groove 7212, completing rapid positioning and hooking; after hooking into place, the driving handle 713 rotates along the second direction opposite to the first direction, so that the driving handle 713 is reset to the initial position. When separation is required, the user rotates the driving handle 713 along the first direction again, driving the connecting hook 711 out of the hook groove 7212, achieving rapid separation; after separation, the driving handle 713 is reset along the second direction. With the above structural design, no additional tools are required for both connection and separation operations, and the entire process can be completed by rotating the driving handle 713 with one hand, making the operation simple, convenient and efficient.

[0130] Reference Figures 16 to 24 In one embodiment, the connecting hook 711 includes a connecting shaft 7111, the driving handle 713 is provided with a connecting hole 522, and the connecting shaft 7111 is rotatably passed through the connecting hole 522; the fifth connecting member 710 also includes an elastic structure 714 and a transmission structure 715, the elastic structure 714 is sleeved on the connecting shaft 7111, and the two ends of the elastic structure 714 are connected to the driving handle 713; the transmission structure 715 is provided on the connecting shaft 7111, and is used to drive the elastic structure 714 to twist following the rotation of the connecting shaft 7111.

[0131] In this embodiment, the connecting shaft 7111 is located on one side of the first rotating shaft 7121, and the length direction of the connecting shaft 7111 is parallel to the length direction of the first rotating shaft 7121. The connecting shaft 7111 is inserted into the connecting hole 522 with a clearance fit so as to be rotatably inserted into the connecting hole 522. At the same time, the connecting hook 711 further includes a hook rod 7112 and a connecting rod 7113, wherein the hook rod 7112 is located on one side of the connecting shaft 7111 and is parallel to the connecting shaft 7111. There are two connecting rods 7113, which are parallel to the hook rod 7112 and connected to the connecting shaft 7111. The length direction of the connecting rod 7113 is perpendicular to the length direction of the hook rod 7112 and the length direction of the connecting shaft 7111.

[0132] The elastic structure 714 is a spring, and both ends of the elastic structure 714 are fixedly connected to the driving handle 713; the transmission structure 715 is a transmission screw, transmission pin or transmission column, and the transmission structure 715 is fixedly installed on the connecting shaft 7111. The length direction of the transmission structure 715 is perpendicular to the length direction of the connecting shaft 7111, and part of the structure of the elastic structure 714 is sleeved on the transmission structure 715.

[0133] The elastic structure 714 used in conjunction with the transmission structure 715 can store elastic potential energy through torsional deformation during the rotation of the connecting shaft 7111. This not only releases the stored elastic potential energy to assist the movement of the driving handle 713 when it is reset, thereby reducing manual operating force and intensity, thus achieving a labor-saving effect. Furthermore, when the connecting hook 711 is hooked into the hooking groove 7212, the elastic potential energy is converted into a preload force, ensuring a tight fit between the connecting hook 711 and the hooking groove 7212, thereby enhancing the connection strength and reliability of the fifth connecting member 710 and the sixth connecting member 720.

[0134] Reference Figure 16 、 Figures 18 to 23 as well as Figure 25 In one embodiment, the fifth connecting member 710 further includes a limiting hook 716 , which is rotatably disposed on the driving handle 713 and limits the rotation of the driving handle 713 by hooking on the mounting member 210 .

[0135] In this embodiment, a second rotating shaft 7161 is fixedly mounted on the driving handle 713, and a limiting hook 716 is rotatably mounted on the second rotating shaft 7161. The second rotating shaft 7161 is located on one side of the first rotating shaft 7121, and its length is parallel to the length of the first rotating shaft 7121. It is understood that the second rotating shaft 7161 can also be rotatably mounted on the driving handle 713, and the limiting hook 716 is fixedly mounted on the second rotating shaft 7161. Furthermore, a mating groove 213 is provided on the surface of the mounting member 210 near the fifth connecting member 710, into which a portion of the limiting hook 716 is inserted. A mating plate 214 is also provided on the surface of the mounting member 210 near the fifth connecting member 710, and a portion of the mating plate 214 covers a portion of the notch of the mating groove 213. The limiting hook 716 is hooked onto the surface of the mating plate 214 near the mating groove 213 to be secured to the mounting member 210.

[0136] When the third connecting assembly is connected, the limiting hook 716 cooperates with the connecting hook 711 to achieve a double lock. Specifically, the connecting hook 711 locks the display module by hooking into the hooking slot 7212, and the limiting hook 716 locks the driving handle 713 by hooking into the mounting member 210. This ensures that the connecting hook 711 and the hooking slot 7212 always maintain a tight fit, thereby ensuring the reliability and stability of the connection between the fifth connecting member 710 and the sixth connecting member 720. When the third connecting assembly is disconnected, the limiting hook 716 locks the driving handle 713 in a set position by hooking onto the mounting member 210, facilitating structural stability during storage or transportation.

[0137] Reference Figure 23In addition, a torsion spring 7162 is sleeved on the second rotating shaft 7161, a first end of the torsion spring 7162 is fixedly connected to the driving handle 713, a mounting hole is provided on the limiting hook 716, and the second end of the torsion spring 7162 is passed through the mounting hole.

[0138] Reference Figures 19 to 22 、 Figure 24 as well as Figure 26 In one embodiment, the sixth connecting member 720 includes a sixth connecting body 721 and a buffer structure 722, the sixth connecting body 721 has a connecting surface 7211, a hooking groove 7212 is set on the connecting surface 7211, and a movable groove 7213 is set on the inner wall surface of the hooking groove 7212 away from the connecting surface 7211; the buffer structure 722 is set in the movable groove 7213 and the hooking groove 7212 while sliding along the first direction; the third connecting component has a separated state, and when the third connecting component is in the separated state, the connecting hook 711 is located outside the hooking groove 7212; in the process of the third connecting component switching from the separated state to the connected state, the connecting hook 711 pushes the buffer structure 722 to move away from the connecting surface 7211; in the process of the third connecting component switching from the connected state to the separated state, the buffer structure 722 pushes the connecting hook 711 to move toward the connecting surface 7211.

[0139] In this embodiment, the sixth connecting body 721 is a connecting seat. When the third connecting assembly is in the connected state, the connecting surface 7211 is the surface of the sixth connecting body 721 that is away from the fifth connecting body 712, and the first direction is parallel to the direction of the line connecting the fifth connecting body 712 to the sixth connecting body 721. The movable groove 7213 is disposed on the bottom of the hooking groove 7212 and is arranged along the first direction with the hooking groove 7212. The buffer structure 722 can be a buffer spring. When the third connecting assembly switches from the disconnected state to the connected state, the buffer structure 722 is gradually compressed by the connecting hook 711 to accumulate elastic potential energy. When the third connecting assembly switches from the connected state to the disconnected state, the buffer structure 722 applies an elastic thrust toward the connecting surface 7211 to the connecting hook 711 to release the elastic potential energy.

[0140] During the transition from the disconnected to the connected state of the third connecting assembly, the sliding buffer structure 722 not only absorbs impact and acts as a buffer, preventing the connecting hook 711 from violently colliding with the inner wall of the hooking slot 7212, but also reduces initial insertion resistance, making insertion of the connecting hook 711 into the hooking slot 7212 more effortless. During the transition from the connected to the disconnected state, the buffer structure 722 pushes the connecting hook 711 toward the connecting surface 7211, assisting in disengaging the connecting hook 711 from the hooking slot 7212 and reducing the pulling force required to disengage the connecting hook 711, thus achieving a labor-saving effect. Furthermore, to prevent the connecting hook 711 from continuing to move within the hooking slot 7212, when the third connecting assembly is in the connected state, the inner wall of the hooking slot 7212, facing away from the connecting surface 7211, contacts the connecting hook 711 to prevent further movement of the connecting hook 711 away from the connecting surface 7211.

[0141] Reference Figure 24 as well as Figure 26 In one embodiment, the buffer structure 722 includes a buffer body 7221 and a second elastic body 7223, and the second elastic body 7223 is arranged on the side of the buffer body 7221 away from the connecting surface 7211; in the process of the third connecting component switching from the separated state to the connected state, the connecting hook 711 contacts the buffer body 7221, and the buffer body 7221 applies a thrust set away from the connecting surface 7211 to the second elastic body 7223; in the process of the third connecting component switching from the connected state to the separated state, the connecting hook 711 contacts the buffer body 7221, and the second elastic body 7223 applies a thrust set toward the connecting surface 7211 to the buffer body 7221.

[0142] In this embodiment, the buffer body 7221 is made of stainless steel. It is understood that the buffer body 7221 can also be made of other rigid or hard components. The second elastic body 7223 is a spring arranged along the first direction. The end of the second elastic body 7223 closest to the buffer body 7221 can only contact the surface of the buffer body 7221 away from the connection surface 7211. Simultaneously, the end of the second elastic body 7223 away from the buffer body 7221 is compressed by contact with the inner wall of the movable groove 7213. The second elastic body 7223 is used to apply an elastic thrust toward the connection surface 7211 to the connecting hook 711 through the buffer body 7221.

[0143] During the process of switching the third connecting component from the separated state to the connected state, the second elastic body 7223 is gradually compressed under the action of the thrust applied by the buffer body 7221 to accumulate elastic potential energy; during the process of switching the third connecting component from the connected state to the separated state, the second elastic body 7223 releases elastic potential energy to the connecting hook 711 through the buffer body 7221 to push the connecting hook 711 into the hooking groove 7212.

[0144] In addition, the buffer body 7221 and the second elastomer 7223 are installed in the movable groove 7213 as independent components. If the buffer body 7221 or the second elastomer 7223 is worn, there is no need to replace the buffer structure 722 as a whole. Only the buffer body 7221 or the second elastomer 7223 needs to be replaced separately, which reduces maintenance costs.

[0145] Reference Figure 25 as well as Figure 27 In one embodiment, a receiving groove 7222 is provided on the surface of the buffer body 7221 close to the connecting surface 7211 , and when the third connecting component is in a connected state, the connecting hook 711 is embedded in the receiving groove 7222 .

[0146] In this embodiment, when the third connecting assembly is in the connected state, a portion of the connecting rod 7113 of the connecting hook 711 is embedded in the accommodating groove 7222 .

[0147] The receiving groove 7222 not only effectively limits the shaking and displacement of the connecting hook 711, thereby improving the connection strength and reliability of the fifth connecting member 710 and the sixth connecting member 720, but also acts as a stop, preventing the connecting hook 711 from being over-inserted and causing overload pressure on the second elastic body 7223. Furthermore, after the connecting hook 711 is embedded in the receiving groove 7222, the load (such as tension and shear force) is evenly transmitted to the buffer body 7221 through the inner wall surface of the receiving groove 7222, rather than acting only on the inner wall surface of the hooking groove 7212. This reduces stress concentration and extends the service life of the buffer body 7221.

[0148] Reference Figure 25 as well as Figure 27 In one embodiment, a limiting body 7224 is provided on the buffer body 7221 away from the connecting surface 7211, and the second elastic body 7223 is sleeved on the limiting body 7224 and connected to the buffer body 7221; a movable groove 7214 is provided on the inner wall surface of the movable groove 7213 away from the connecting surface 7211, and the limiting body 7224 and the second elastic body 7223 are inserted into or removed from the movable groove 7214 along the first direction.

[0149] In this embodiment, the limiting body 7224 is a limiting column and is an integrally formed part with the buffer body 7221; the end of the second elastic body 7223 close to the buffer body 7221 is fixedly installed on the surface of the buffer body 7221 away from the connecting surface 7211; the movable groove 7214 is arranged along the first direction.

[0150] The stopper 7224 not only restricts the second elastic body 7223 from randomly oscillating in the radial direction, ensuring that the second elastic body 7223 is compressed and extended only in the first direction, but also, in conjunction with the movable groove 7214, provides positioning and guidance, ensuring that the buffer body 7221 can slide accurately in the first direction. Furthermore, the movable groove 7214 provides space for the stopper 7224 to move, effectively preventing interference between the stopper 7224 and the inner wall of the movable groove 7213.

[0151] In addition, in order to enhance the buffering effect, the number of second elastic bodies 7223 is two, and the two second elastic bodies 7223 are arranged at intervals along a direction perpendicular to the first direction; the number of limiting bodies 7224 is two, and the two limiting bodies 7224 are respectively arranged in a one-to-one correspondence with the two second elastic bodies 7223; the number of movable grooves 7214 is also two, and the two movable grooves 7214 are respectively arranged in a one-to-one correspondence with the two limiting bodies 7224.

[0152] Reference Figure 17 、 Figure 24 as well as Figure 26 In one embodiment, the fifth connecting body 712 is provided with a first magnetic block 7122, and the sixth connecting body 721 is provided with a second magnetic block 7215; when the third connecting component is in a connected state, the first magnetic block 7122 and the second magnetic block 7215 are magnetically attracted to each other.

[0153] In this embodiment, the first magnetic block 7122 and the second magnetic block 7215 are N-pole magnets and S-pole magnets, respectively. When the third connecting assembly is in a connected state, the surface of the fifth connecting body 712 near the sixth connecting body 721 is provided with a first mounting groove 212, and the first magnetic block 7122 is fixedly mounted in the first mounting groove 212 (e.g., by means of connecting screws or interference fit), and the surface of the first magnetic block 7122 away from the first mounting groove 212 is flush with the surface of the fifth connecting body 712 where the first mounting groove 212 is provided. The surface of the sixth connecting body 721 near the fifth connecting body 712 is provided with a second mounting groove 212, and the second magnetic block 7215 is fixedly mounted in the second mounting groove 212 (e.g., by means of connecting screws or interference fit), and the surface of the second magnetic block 7215 away from the second mounting groove 212 is flush with the surface of the second connecting body 511 where the second mounting groove 212 is provided. It is understandable that the fifth connection body 712 and the sixth connection body 721 can also be detachably connected by plugging or snapping.

[0154] In addition, when the third connecting assembly is in the connected state, the surface of the fifth connecting body 712 close to the sixth connecting body 721 is kept in contact with the surface of the sixth connecting body 721 close to the fifth connecting body 712 .

[0155] The hooking connection between the connecting hook 711 and the hooking groove 7212 forms a rigid connection, which directly limits the relative displacement of the fifth connecting member 710 and the sixth connecting member 720 through mechanical limiting; the magnetic adsorption of the first magnetic block 7122 and the second magnetic block 7215 forms a flexible auxiliary connection, further enhancing the connection strength and reliability of the fifth connecting member 710 and the sixth connecting member 720.

[0156] At the same time, the first magnetic block 7122 and the second magnetic block 7215 used in conjunction with each other are also self-guiding. When the fifth connecting body 712 and the sixth connecting body 721 approach each other, the magnetic force will automatically guide the two to align along the first direction, reducing the difficulty for the user to manually align the fifth connecting body 712 and the sixth connecting body 721. This pre-alignment process creates convenient conditions for the connecting hook 711 to be accurately hooked into the hooking groove 7212, thereby improving the connection efficiency of the fifth connecting member 710 and the sixth connecting member 720.

[0157] Reference Figure 17 、 Figure 24 、 Figure 26 as well as Figure 27In one embodiment, the sixth connecting body 721 is provided with a guide structure 723, which is arranged on the buffer structure 722 and can move back and forth along the first direction; the fifth connecting body 712 is provided with a second mounting groove 7123, and a guide sleeve 717 is provided in the second mounting groove 7123; when the third connecting component is in a connected state, the guide structure 723 is inserted into the guide sleeve 717; when the third connecting component is in a separated state, the guide structure 723 is located outside the guide sleeve 717.

[0158] In this embodiment, a first mounting groove 7216 is provided on the inner wall surface of the movable groove 7213 away from the connecting surface 7211. The first mounting groove 7216 penetrates along the first direction to the outside of the fifth connecting body 712. The guide structure 723 is a guide pin. A connecting hole 522 is provided on the surface of the buffer body 7221 away from the connecting surface 7211. The guide structure 723 is fixedly inserted into the connecting hole 522 by interference fit or threaded fit.

[0159] When the third connecting assembly is in the connected state, the second mounting groove 7123 is provided on the surface of the fifth connecting body 712 adjacent to the sixth connecting body 721, and the second mounting groove 7123 is connected to the first mounting groove 7216. The guide sleeve 717 is arranged along the first direction, and the inner diameter of the guide sleeve 717 is larger than the maximum diameter of the guide structure 723. The surface of the fifth connecting body 712 is provided with a communication hole that communicates with the second mounting groove 7123. The communication hole is provided with a limit screw, limit screw, or limit pin fixedly connected to the guide sleeve 717. It is understood that the guide sleeve 717 can also be fixedly installed in the second mounting groove 7123 by means of interference fit, clip connection, threaded connection, etc.

[0160] When the buffer structure 722 is pushed by the connecting hook 711, it moves away from the connecting surface 7211. The guide structure 723 and guide sleeve 717 provide a rigid guide for the buffer structure 722, ensuring that the buffer structure 722 can slide precisely along the first direction and effectively preventing the buffer structure 722 from shifting. Furthermore, the guide sleeve 717 effectively prevents direct friction between the guide structure 723 and the wall of the second mounting slot 7123, reducing wear and extending the service life of the buffer body 7221.

[0161] Furthermore, the diameter of the notch in the first mounting groove 7216 that communicates with the movable groove 7213 is smaller than the diameter of the limiting cap 5121 of the guide structure 723, thereby preventing the guide structure 723 from fully entering the movable groove 7213. The main structure of the buffer body 7221 completely covers the notch in the first mounting groove 7216 that communicates with the movable groove 7213, thereby preventing the buffer body 7221 from fully entering the first mounting groove 7216. This structure can bidirectionally limit the range of movement of the buffer body 7221 within the movable groove 7213, effectively ensuring the reliability of the buffer body 7221's movement in the first direction.

[0162] In summary, the display module and display device provided by this embodiment have at least the following beneficial technical effects: Due to the detachable design of protective cover 120, maintenance can be performed on electrical components 110 by simply opening protective cover 120 without disassembling the entire power supply assembly 100. This reduces the number of disassembly steps, simplifies the maintenance process, and improves maintenance efficiency. Furthermore, protective cover 120 also serves to protect electrical components 110.
