Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0053] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0056] like Figure 1 , Figure 3 , Figure 9 As shown, this embodiment of the invention provides a display screen device, including: a cabinet support 10, a first mounting groove 11 is provided on the front side of the cabinet support 10, and a first through hole 111 is provided through the first mounting groove 11 in the front-rear direction; a display module 20, the display module 20 is embedded in the first mounting groove 11, and the display module 20 is provided with a second through hole 201 coaxial with the first through hole 111; a connector 30, the connector 30 is rotatably passed through the first through hole 111 and the second through hole 201, so that the cabinet support 10 and the display module 20 form a detachable connection; wherein, the end of the connector 30 extending from the first through hole 111 to the second through hole 201 is provided with a first slot, and the end of the connector 30 extending from the second through hole 201 to the first through hole 111 is provided with a second slot, both the first slot and the second slot are used for inserting an operating tool, so that the operating tool can drive the connector 30 to rotate to a locking angle or an unlocking angle.

[0057] It is understood that in this embodiment, a first slot and a second slot are respectively provided at both ends of the connector 30, both of which allow the operating tool to be inserted and rotated to the locking angle or the unlocking angle, thereby realizing the front maintenance of the display module. This effectively solves the problems of limited operating space, high maintenance cost and high safety risk caused by the traditional rear maintenance of the display, and significantly improves the convenience and efficiency of maintenance.

[0058] It should be explained that, in this embodiment, the locking angle refers to the position where the connector 30 is rotated to an angle range, so that the cabinet support 10 and the display module 20 are securely connected; the unlocking angle refers to the position where the connector 30 is rotated to another angle range, so that the secure connection between the cabinet support 10 and the display module 20 is released, allowing them to separate. In a feasible maintenance process for the display device of this embodiment, an operating tool (such as a screwdriver or hex wrench) can be inserted into the first or second slot at either end of the connector 30 from the front or back of the display screen, and the connector 30 is rotated to the unlocking angle to release the lock between the display module 20 and the cabinet support 10, after which the display module 20 can be removed. During installation, after placing the display module 20 into the mounting slot, the connector 30 is inserted at the unlocking angle and rotated to the locking angle to complete the fixation. Those skilled in the art will understand that the directional terms such as "front" and "rear" mentioned in the above embodiments are based on the viewing direction during normal use of the display screen and do not constitute a limitation on the scope of protection of this invention. The scope of protection of this invention should be determined by the claims.

[0059] like Figures 1 to 4 as well as Figure 6 , Figure 7 As shown, in some embodiments, a first magnetic element 112 is provided in the first mounting slot 11, and a second magnetic element corresponding to the first magnetic element 112 is provided in the display module 20. The first magnetic element 112 and the second magnetic element are magnetically connected.

[0060] It is understandable that if the cabinet bracket 10 and the display module 20 are connected solely by the connector 30, there are potential problems of alignment difficulties and unstable installation during the positioning and assembly stage. Specifically, when the display module 20 is embedded into the first mounting slot 11, the operator needs to simultaneously and precisely align the second through hole 201 and the first through hole 111 so that the connector 30 can be smoothly inserted. Without auxiliary positioning, the module is prone to shifting or slipping, especially when working at heights. It is difficult to stabilize the module and perform alignment operations with one hand at the same time, which not only reduces installation efficiency but may also damage the interface or cables due to repeated adjustments. Based on this, this embodiment uses a first magnetic component 112 and a second magnetic component that attract each other between the first mounting slot 11 and the display module 20 to achieve auxiliary positioning and initial fixation using magnetic force. When the display module 20 approaches the first mounting slot 11, the magnetic force will automatically guide it to the accurate installation position and automatically align the first through hole 111 with the second through hole 201. At the same time, the magnetic attraction can provide sufficient temporary fixing force for the display module 20 before the connector 30 is inserted and locked, so as to keep it stable, thereby achieving a fast and accurate installation effect and significantly improving installation efficiency and ease of operation.

[0061] In some embodiments, the first mounting groove 11 is provided with a plurality of first through holes 111 and a plurality of first magnetic elements 112. The plurality of first magnetic elements 112 should be provided along the edge of the first mounting groove 11, so that when the display module 20 is embedded, the uniformly distributed magnetic attraction ensures a complete fit between the module and the mounting groove, avoiding installation tilting or gap problems caused by uneven force at a single point. The plurality of first through holes 111 should also be provided along the edge of the first mounting groove 11, so that the peripherally distributed connection points provide a balanced mechanical locking force to the display module 20, preventing warping or deformation that may occur due to force on one side. Furthermore, two first through holes 111 are also provided around the center of the first mounting groove 11 to provide additional central locking points, effectively suppressing potential vibration or deformation in the center of the display module 20 and improving the rigidity and stability of the overall structure. The first magnetic element 112 and the second magnetic element can both be magnets, or one can be a magnet and the other a metal, as long as they can be attracted by magnetism.

[0062] Optionally, four first magnetic elements 112 are provided, with two first magnetic elements 112 on the upper side and two first magnetic elements 112 on the lower side of the first mounting groove 11, forming a symmetrical magnetic attraction layout to provide a balanced vertical attraction force for the display module 20. Six first through holes 111 are provided, with two first through holes 111 on the upper side, two first through holes 111 on the lower side of the first mounting groove 11, and two more first through holes 111 in the middle surrounding the center of the first mounting groove 11, forming a composite connection system that includes peripheral locking and central reinforcement. Preferably, the four first through holes 111 located on the upper and lower sides are staggered with the four first magnetic elements 112 on the same side, so that the magnetic positioning points and mechanical locking points form a uniformly distributed support network along the edge of the first mounting groove 11.

[0063] like Figures 8 to 11 As shown, in some embodiments, the display device further includes a connecting bracket 40, which is fixed to one end of the second through hole 201 facing the first through hole 111. The connecting bracket 40 is provided with a first limiting part 41, and the connector 30 is provided with a second limiting part. The second limiting part is rotatably inserted through the first limiting part 41 so that the axial movement of the connector 30 relative to the second through hole 201 is limited.

[0064] In this embodiment, the connecting bracket 40 is fixedly connected to the display module 20, and the first limiting part 41 cooperates with the second limiting part of the connector 30 to axially limit the connector 30 on the display module 20. Thus, when the connector 30 is rotated to the unlocking angle and the display module 20 is separated from the housing bracket 10, the display module 20 can drive the connector 30 to separate from the housing bracket 10 together, effectively avoiding the risk of the connector 30 falling off or being lost from the module, reducing the risk of small parts falling in complex working environments such as high altitudes, and further improving the safety and convenience of maintenance operations.

[0065] In some embodiments, the first through hole 111 includes a first through portion 1111 and a second through portion 1112 formed by radially extending the first through portion 1111; the connector 30 includes a rod portion 31 and a locking portion 32, the locking portion 32 is formed by radially extending outward from the rod portion 31, and the second limiting portion is formed by radially recessing the rod portion 31, the rod portion 31 passing through the first through portion 1111; wherein, when the connector 30 is rotated to the locking angle, the locking portion 32 is located on the side of the first through hole 111 away from the second through hole 201, and the projection of the locking portion 32 toward the second through hole 201 is misaligned with the second through portion 1112; when the connector 30 is rotated to the unlocking angle, the projection of the locking portion 32 toward the second through hole 201 coincides with the second through portion 1112.

[0066] Understandably, when the connector 30 passes through the first through hole 111 and the second through hole 201 and rotates to the locking angle, the latching part 32 and the second through part 1112 are misaligned in the projection, causing the latching part 32 to lock onto the back of the first through hole 111, thereby axially tightening and fixing the housing bracket 10 and the display module 20. When disassembly is required, simply rotate the connector 30 to the unlocking angle so that the latching part 32 and the second through part 1112 coincide in the projection, and the connector 30 can be easily pulled out of the first through hole 111, achieving rapid separation. It should be noted that in this embodiment, a first slot and a second slot are respectively provided at both ends of the connector 30, so that the operating tool can be inserted into the second slot from the front of the display device and rotated to rotate the connector 30 to the locking angle or the unlocking angle; or the operating tool can be inserted into the first slot from the rear of the display device for operation.

[0067] like Figures 1 to 7As shown, in some embodiments, a second mounting groove 12 is also provided in the first mounting groove 11; the display device also includes an electronic component mounting plate 50 and an electronic component, the electronic component mounting plate 50 is embedded in the second mounting groove 12, the electronic component is mounted on the side of the electronic component mounting plate 50 away from the display module 20, the electronic component mounting plate 50 is located between the display module 20 and the cabinet bracket 10; the display device also includes a threaded component, the second mounting groove 12 is provided with a threaded hole, the electronic component mounting plate 50 is provided with a third through hole corresponding to the threaded hole, the threaded component passes through the third through hole and the threaded hole, and the threaded component is threadedly engaged with the threaded hole, the nut of the threaded component is located on the side of the third through hole away from the threaded hole.

[0068] It should be explained that this embodiment achieves a highly modular design of the display device by integrating a second mounting groove 12 within the first mounting groove 11 and mounting the electronic components therein via the electronic component mounting plate 50. Furthermore, the nut of the threaded component is located on the side of the third through hole away from the threaded hole, i.e., the side facing the display module 20. This allows for easy removal of the threaded component from the front of the display device when maintenance or replacement of the electronic components is required; simply remove the display module 20 first, and then disassemble the device to access the threaded component. This allows the entire electronic component mounting plate 50, along with the electronic components, to be removed. The second mounting groove 12 is a through groove, meaning that the periphery of the electronic component mounting plate 50 abuts against the periphery of the second mounting groove 12.

[0069] like Figure 7 As shown, in some embodiments, a plurality of first mounting slots 11 are arranged along a first direction; the electronic component includes a plurality of circuit boards 51 arranged along the first direction, with a first connector 512 disposed on the side of the circuit board 51 facing the electronic component mounting plate 50, and the electronic component mounting plate 50 having a first through hole for the first connector 512 to pass through, the first connector 512 extending to the first mounting slot 11 through the first through hole; the display module 20 has a second connector disposed on the position facing the second mounting slot 12, the second connector being used to mate with the first connector 512 to realize electrical connection between the circuit board 51 and the display module 20; the electronic component also includes an adapter plate 511 bridging adjacent circuit boards 51, the adapter plate 511 being used to electrically connect adjacent circuit boards 51. Preferably, one electronic component mounting plate 50 is disposed in one second mounting slot 12, and one circuit board 51 is mounted on one electronic component mounting plate 50.

[0070] Understandably, unlike the traditional approach of horizontally covering multiple display modules with a single large circuit board, this embodiment employs multiple independent circuit boards 51 arranged along a first direction, with electrical connections between them achieved through an adapter board 511. Therefore, when any circuit board 51 malfunctions, maintenance personnel only need to remove the corresponding electronic component mounting plate 50 to replace or repair the individual circuit board 51, without needing to disassemble and replace the large overall circuit board. This not only significantly reduces the complexity and time cost of maintenance operations but also substantially reduces the cost and space required for spare parts inventory—only standard-sized individual circuit boards 51 need to be stocked, eliminating the need to prepare multiple large overall circuit boards for different sized enclosures.

[0071] like Figure 8 and Figure 12 As shown, in some embodiments, a pressure plate 52 and a sealing ring 53 are provided on the side of the first perforation facing the display module 20. The sealing ring 53 includes a peripheral portion 532 and a bottom portion 531 extending radially outward from the outer periphery of the peripheral portion 532 toward one end of the first perforation. The first connector 512 passes through the second perforation formed by the peripheral portion 532. The pressure plate 52 is sleeved on the outside of the peripheral portion 532, and the bottom portion 531 is sandwiched between the pressure plate 52 and the electronic component mounting plate 50. The pressure plate 52 is detachably connected to the electronic component mounting plate 50.

[0072] Understandably, traditional sealing solutions typically involve placing independent gaskets at the two ports facing the display module 20 and the electronic components through the first perforation to prevent liquid from penetrating the electronic components. This approach suffers from complex assembly processes, multiple sealing interfaces, and the risk of gasket displacement or uneven aging over long-term use, affecting sealing reliability. This embodiment employs a one-piece molded sealing ring 53, which tightly wraps around the first connector 512 via its peripheral portion 532, forming the first radial sealing barrier. The bottom portion 531 is evenly pressed against the surface of the electronic component mounting plate 50 by the pressure plate 52, forming the second end-face sealing barrier, significantly improving the reliability of waterproofing. Furthermore, the detachable connection of the pressure plate 52 makes the installation, replacement, and maintenance of the sealing ring 53 extremely convenient. During maintenance, only the pressure plate 52 needs to be removed to replace the sealing ring 53 or repair the connector, without needing to disassemble or replace the entire electronic component mounting plate 50.

[0073] like Figure 6 and Figure 7As shown, in some embodiments, the display device further includes a housing 60 and a cover 61. The housing 60 is connected to the edge of the electronic component mounting plate 50 on the side where electronic components are mounted, and the cover 61 is movably connected to the side of the housing 60 away from the electronic component mounting plate 50. The housing 60, cover 61, and electronic component mounting plate 50 together form a mounting cavity for accommodating electronic components. The cover 61 is movable to open or seal the mounting cavity. The second mounting groove 12 is a through groove, meaning that the electronic component mounting plate 50 is connected to the periphery of the second mounting groove 12 by screws, and the electronic components are mounted on the side of the electronic component mounting plate 50 away from the display module 20.

[0074] It is understood that in this embodiment, the housing 60, cover 61, and electronic component mounting plate 50 together form an independent mounting cavity, providing a protective space for the electronic components that is physically isolated from the display module 20 and the housing bracket 10. It should be noted that the second mounting slot 12 is designed as a through slot, and the electronic component mounting plate 50 is fixed to the periphery of the through slot with screws. This allows the electronic components to be independently housed within the mounting cavity formed by the housing 60 and cover 61, creating a clear front-rear partition with the display module 20. When maintenance of the electronic components is required, only the cover 61 needs to be opened to operate directly from the rear of the housing, achieving independent rear maintenance of the electronic components without affecting the front display module 20.

[0075] Furthermore, the housing 60 encloses multiple electronic component mounting plates 50 within its interior. That is, all circuit boards 51 and adapter boards 511 in the electronic components of the display device in this embodiment are housed within the mounting cavity formed by the housing 60, the cover 61, and the electronic component mounting plates 50. This greatly simplifies the internal structure of the housing, reduces the number of independent parts, and lowers assembly complexity. Moreover, when maintenance is required, all electronic components can be accessed simply by opening one cover 61, eliminating the need for repeated disassembly and reassembly of multiple dispersed modules, significantly improving maintenance efficiency. The electronic components also include a power supply and a receiver card, which will not be described in detail here.

[0076] In some embodiments, the enclosure bracket 10 is provided with a cable concealment box 70, which is located at one end of the enclosure 60 along a first direction. A connecting wire is provided inside the cable concealment box 70. A first cable routing hole for the connecting wire to pass through is provided between the cable concealment box 70 and the enclosure 60. A second cable routing hole for the connecting wire to exit the enclosure bracket 10 is provided on one side of the cable concealment box 70.

[0077] Understandably, traditional display cabinets typically leave excess cables scattered or simply bundled inside, which affects internal airflow and poses a risk of cable pulling and wear. In this embodiment, the cables are neatly organized within a separate, enclosed space, avoiding a messy arrangement inside the cabinet. This improves the tidiness of the internal space and eliminates potential heat dissipation problems or signal interference caused by tangled cables. Furthermore, the centralized cable management design using the cable management box 70 greatly facilitates cable handling during installation and maintenance. Maintenance personnel no longer need to search for target cables in complex cable bundles; they can simply open or operate the cable management box 70 to centrally manage all cables.

[0078] like Figures 13 to 15 As shown, in some embodiments, the display device further includes a pop-out mechanism 80. When the connector 30 rotates to the unlocking angle, the pop-out mechanism 80 is triggered and applies a popping force to the display module 20 to disengage it from the first mounting slot 11. It is understood that this embodiment, by setting the pop-out mechanism 80, effectively solves the problem that the display module 20 may be difficult to remove after unlocking due to tight fit or attraction by the first magnetic component 112 and the second magnetic component. The pop-out mechanism 80 is linked to the rotation operation of the connector 30, automatically triggering when the connector 30 rotates to the unlocking angle, providing an initial disengagement force to the display module 20, causing it to partially move out of the mounting slot, providing a gripping space for maintenance personnel.

[0079] The pop-out mechanism 80 can be located on either the housing support 10 or the display module 20. Its purpose is simply to generate a force that pulls the housing support 10 and the display module 20 away from each other after the connecting member 30 is rotated to the unlocking angle, thus helping workers or robots remove the display module 20 from the first mounting slot 11. In some embodiments, the pop-out mechanism 80 may include a linkage wheel 81 and a compression elastic member 82. The inner ring of the linkage wheel 81 is fitted onto the connecting member 30, and one end of the compression elastic member 82 abuts against the display module 20, while the other end abuts against the linkage wheel 81. Specifically, the display module is provided with a first groove for accommodating the compression elastic member 82 and a second groove for accommodating the linkage wheel 81, and the first groove and the second groove are connected; when the connector 30 is in the locking angle, the end of the compression elastic member 82 facing the display module 20 abuts against the first groove, and the end facing the housing bracket 10 abuts against the linkage wheel 81; when the connector 30 rotates to the unlocking angle, the connector 30 drives the linkage wheel 81 to rotate, so that the linkage wheel 81 and the compression elastic member 82 are misaligned, thereby releasing the limit of the linkage wheel 81 on the compression elastic member 82, and the compression elastic member 82 is released and applies an elastic force to the housing bracket 10 to move the display module 20 away.

[0080] Understandably, when the connector 30 is in the locked angle, the physical part of the linkage wheel 81 acts as a "moving stop," continuously pressing and compressing the elastic member 82 to maintain its compressed energy storage state. When the connector 30 rotates to the unlocked angle, the linkage wheel 81 rotates synchronously, and the linkage wheel 81 is displaced from the elastic member 82, removing the mechanical obstacle blocking the movement path of the elastic member 82. The constrained elastic potential energy of the elastic member 82 is released, and its reaction force acts directly on the display module 20, thereby generating a popping force that separates it from the cabinet support 10.

[0081] Preferably, the compression elastic element 82 is a helical compression spring. Furthermore, the linkage wheel 81 is made of engineering plastic to reduce weight and ensure smooth rotation with the connecting member 30.

[0082] In practical applications, the pop-up mechanism based on the compression elastic element 82 has the following drawbacks: when the connecting member 30 rotates to the unlocking angle, the compression elastic element 82 releases instantaneously, causing a significant impact on the display module 20 and the housing bracket 10, posing a risk of damage; and when reassembling the display module 20, the compression elastic element 82 is difficult to reset to the storage position between the linkage wheel 81 and the first slot, making the assembly operation extremely inconvenient. To solve the above problems, this application makes the following improvements to the pop-up mechanism 80:

[0083] like Figures 16 to 19 As shown, in this embodiment, the ejection mechanism 80 further includes a large gear 83, a small gear 84, an abutment plate 85, a wire harness retractor, and a gear section 33 disposed on the outer ring of the connector 30. The wire harness retractor includes a stator section, a mover section, and a wire harness 86. The stator section is fixedly disposed at the bottom of the first groove; one end of the compression elastic member 82 is connected to the stator section, and the other end is connected to the abutment plate 85. The mover section is sleeved on the outside of the stator section and connected to the inner ring of the small gear 84. The wire harness 86 is wound inside the stator section, with one end extending out of the stator section and connected to the abutment plate 85; through the relative rotation between the stator section and the mover section, the wire harness 86 can be controllably released or wound back. The gear section 33 meshes with the large gear 83, and the large gear 83 further meshes with the small gear 84, thereby forming a multi-stage transmission relationship. The wire harness take-up and take-down device is a known structure (e.g., a device based on the self-retracting principle of a coiled spring), and its specific internal structure will not be described in detail here.

[0084] Specifically, the working process of the pop-out mechanism 80 is as follows:

[0085] When the connector 30 rotates from the locked angle to the unlocked angle: the gear part 33 drives the large gear 83 to rotate, and the large gear 83 drives the small gear 84 to rotate; the small gear 84 causes the moving part and the stator part to rotate relative to each other, so that the wire harness 86 is released from the initial first length to a longer second length; wherein, the first length is less than the vertical distance between the linkage wheel 81 and the bottom of the first groove, while the second length is greater than the opening depth of the first groove. During this process, the elastic force of the compression elastic member 82 is buffered by the controlled release of the wire harness 86, so as to achieve a smooth push-out of the display module 20 and effectively avoid instantaneous impact.

[0086] When the connector 30 rotates from the unlocking angle to the locking angle: the gear part 33 drives the large gear 83 to rotate in the opposite direction, and further drives the small gear 84 and the moving part to reverse, so that the wire harness 86 is rewound from the second length to the first length; the wire harness 86 pulls the abutment plate 85, which drives the compression elastic member 82 to compress and reset to the storage position between the linkage wheel 81 and the bottom of the first groove, preparing for the next disassembly operation and greatly improving the convenience of reassembly.

[0087] In some embodiments, the pop-out mechanism 80 of this embodiment is not limited to providing a single pop-out function. It can also integrate a magnetic bead into the linkage wheel 81 and install a Hall sensor on the circuit board of the display module 20 facing the linkage wheel 81. When the linkage wheel 81 rotates with the connector 30, the position of the magnet on it changes, and the Hall sensor detects different magnetic field signals. Therefore, when the connector 30 facing the circuit board 51 rotates to the unlocking angle, the Hall sensor detects the state, and the circuit board 51 controls the cutting off of power supply to the display module 20, achieving hot-swap protection.
