[0003] The present application belongs to the field of display technology, and more specifically, relates to a display device. Background Art

[0004] Display devices such as smart blackboards often require the installation of external modules such as OPS (Open Pluggable Specification) computers. OPS computers usually include computing elements and image processing units. The computing elements are used to run calculations, and the image processing units are used to process images and video data. In this way, the OPS computer can send the processed images and video data to the display device to improve the display effect of the display device. In the related art, the external module is installed on the display device of the display device, and the display device is usually used to contact the target location such as the wall or platform. Therefore, when the external module needs to be disassembled for repair and replacement, the entire display device needs to be removed from the target location, and then the external module needs to be removed from the display device, which makes the disassembly and assembly of the external module more complicated, which in turn leads to poor convenience in repairing and replacing the external module of the display device.

[0039] The following is a detailed description with reference to the accompanying drawings and embodiments:

[0040] In one embodiment of the present application, referring to Figures 1 and 2, the display device includes a display device 10, a mounting structure 20, and an external module 30. At least a portion of the mounting structure 20 is disposed on a side of the display device 10 along a first direction X. The first direction X intersects with the thickness direction of the display device 10. The mounting structure 20 is provided with a mounting slot 21. The display device 10 is at least partially exposed to the mounting slot 21. The mounting slot 21 is provided with an opening 211 on a side away from the display device 10 along the first direction X. At least a portion of the external module 30 can enter the mounting slot 21 from the opening 211 along the first direction X, and at least a portion of the external module 30 can also be moved out of the mounting slot 21 from the opening 211 along the first direction X. When at least a portion of the external module 30 is located in the mounting slot 21, it can be connected to the display device 10.

[0041] As shown in Figure 1, the display device 10 includes a back shell 11 and a display module 12. The back shell 11 is used to be installed at a target location such as a wall or a platform. The display module 12 is installed on the back shell 11 and is used to display images and text. The mounting structure 20 is installed on the back shell 11 of the display device 10. Among them, at least a portion of the external module 30 is connected to the display device 10, specifically, at least a portion of the external module 30 is connected to the display module 12 of the display device 10. For example, the structure of the display device 10 that is at least partially exposed to the mounting groove 21 can be a socket structure provided on the display module 12, and the external module 30 can be connected to the above-mentioned socket structure.

[0042] The external module 30 is a module that is detachably mounted on the display device and can realize data transmission with the display module 12. As an example, the external module 30 can be an OPS computer.

[0043] At least part of the mounting structure 20 is arranged on one side of the display device 10 along the first direction X, that is, at least part of the mounting structure 20 extends beyond the edge of one side of the display device 10 along the first direction X, so that at least part of the mounting structure 20 does not overlap with the projection of the display device 10 along the thickness direction of the display device 10.

[0044] Specifically, the projection of a portion of the mounting structure 20 along the thickness direction of the display device 10 may overlap with the projection of the display device 10, while the projection of another portion of the mounting structure 20 along the thickness direction of the display device 10 may not overlap with the projection of the display device 10. Alternatively, the projection of the entire mounting structure 20 along the thickness direction of the display device 10 may not overlap with the projection of the display device 10.

[0045] It is understandable that the opening 211 extends beyond the edge of the display device 10 along the first direction X. When the display device is installed on a target location such as a wall or a platform, the opening 211 will not be blocked by the target location.

[0046] The first direction X intersects the thickness direction of the display device 10, which means that the first direction X and the thickness direction of the display device 10 can form an angle greater than 0° and less than 180°, that is, the first direction X and the thickness direction of the display device 10 are not parallel. As an example, the first direction X is the direction X shown in Figure 1, and the direction X is perpendicular to the thickness direction of the display device 10. In use, the first direction X can be roughly the height direction of the display device, and the external module 30 can enter and exit the opening 211 of the mounting slot 21 along the height direction of the display device. As a result, the user can remove and assemble the external module 30 from the bottom of the display device. The first direction X can also be roughly the length direction of the display device, and the external module 30 can enter and exit the opening 211 of the mounting slot 21 along the length direction of the display device. As a result, the user can remove and assemble the external module 30 from the side of the display device.

[0047] When installing the display device provided in the embodiment of the present application, the external module 30 can be connected to the display device 10 by simply inserting the external module 30 into the mounting slot 21 from the opening 211 along the first direction X. When removing the external module 30, the external module 30 can be removed by simply moving the external module 30 out of the mounting slot 21 from the opening 211 along the first direction X. In this way, the external module 30 can be easily assembled and disassembled by simply entering and exiting the opening 211 of the mounting slot 21, eliminating the need to remove the display device from its intended location. This simplifies the assembly and disassembly of the external module 30 and improves the convenience of repairing and replacing the external module 30.

[0048] In one embodiment of the present application, referring to Figures 2 to 5 , the display device 10 is provided with a docking member (not shown), which is exposed at one end of the mounting slot 21 along the second direction Y. At least a portion of the external module 30 is capable of sliding within the mounting slot 21 along the second direction Y. In this manner, the external module 30 can slide to engage with the docking member and can also slide to disengage from the docking member. The first direction X and the second direction Y are perpendicular, and the second direction Y is perpendicular to the thickness of the display device 10.

[0049] The docking piece may be a socket, and the external module 30 is provided with a plug, and is connected to the docking piece through the plug.

[0050] In a possible design, at least a portion of the installation slot 21 extends along the second direction Y, so that the external module 30 can slide along the second direction Y in the installation slot 21 .

[0051] During installation of the external module 30, the external module 30 is first slid into the mounting slot 21 from the opening 211 of the mounting slot 21 along the first direction X. The external module 30 is then driven to slide along the second direction Y until it mates with a mating member at one end of the mounting slot 21 along the second direction Y. During removal of the external module 30, the external module 30 is first driven to slide along the second direction Y until it detaches from the mating member. The external module 30 is then slid out of the mounting slot 21 from the opening 211 along the first direction X. This completes removal of the external module 30.

[0052] The first direction X is the direction X shown in FIG2 , and the second direction Y is the direction Y shown in FIG2 . The directions X and Y are perpendicular to each other, and the first direction X is perpendicular to the second direction Y. The second direction Y is perpendicular to the thickness direction of the display device 10 .

[0053] As an example, the first direction X is approximately the height direction of the display device 10 , and the second direction Y is approximately the length direction of the display device 10 . The first direction X and the second direction Y are perpendicular to each other and perpendicular to the thickness direction of the display device 10 .

[0054] In this way, the installation groove 21 can install the external module 30 and also has a guiding function for the external module 30, which is conducive to the external module 30 sliding to dock with the docking piece and conducting, minimizing the situation where the external module 30 is inserted obliquely during installation, and improving the docking accuracy of the external module 30 and the docking piece.

[0055] In one embodiment of the present application, referring to Figures 2 to 5 , the external module 30 is provided with a first latch 31, and the mounting structure 20 is provided with a second latch 22. When the external module 30 is docked with the docking member, the first latch 31 engages with the second latch 22. This allows at least a portion of the external module 30 to be positioned within the mounting slot 21 along the second direction Y.

[0056] In one possible design, the first clamping member 31 can be a buckle, and the second clamping member 22 can be a buckle that mates with the buckle. Alternatively, in another possible design, the first clamping member 31 can be a claw, and the second clamping member 22 can also be a claw, to achieve mutual engagement. Of course, the first clamping member 31 and the second clamping member 22 are not limited to the two types described above and can also be other forms.

[0057] Thus, when the external module 30 is docked and electrically connected to the docking member, the first clamping member 31 and the second clamping member 22 cooperate to restrain the external module 30 in the mounting slot 21 along the second direction Y. This prevents the external module 30 from loosening and falling out of the mounting slot 21, thereby reducing the risk of poor contact between the external module 30 and the docking member. Furthermore, the provision of the first clamping member 31 and the second clamping member 22 prevents the external module 30 from becoming detached from the docking member during transportation, thereby improving the stability of the electrical connection between the external module 30 and the docking member.

[0058] In one embodiment of the present application, referring to Figures 2 to 5 , a first slot wall 212 is provided on one side of the mounting slot 21 along the first direction X. The second clamping member 22 is disposed opposite the first slot wall 212 along the first direction X. At least a portion of the external module 30 is located between the first slot wall 212 and the second clamping member 22 along the first direction X.

[0059] In one implementation, at least a portion of the external module 30 is limited to the first slot wall 212 along the first direction X; or, in another implementation, at least a portion of the external module 30 is limited to the second clamping member 22 along the first direction X; or, in yet another implementation, at least a portion of the external module 30 is limited to both the first slot wall 212 and the second clamping member 22 along the first direction X.

[0060] In this way, after the external module 30 enters the installation slot 21 , it can slide in the installation slot 21 and will not fall off from the installation slot 21 along the first direction X when sliding in the installation slot 21 , thereby improving the installation stability of the external module 30 .

[0061] In one embodiment of the present application, referring to Figures 2 to 5 , the external module 30 further includes a main structure 32. At least a portion of the main structure 32 is configured to slide within the mounting slot 21 and to engage with the docking member. A first clip 31 is rotatably connected to the main structure 32. Furthermore, the first clip 31 can rotate relative to the main structure 32 to engage with the second clip 22, and can also rotate relative to the main structure 32 to release from the second clip 22.

[0062] When installing the external module 30, the first clamping member 31 can be driven to rotate relative to the main structure 32 and the main structure 32 can be slid until it mates with the docking member. Then, the first clamping member 31 can be driven to rotate until it engages with the second clamping member 22, thereby restraining the main structure 32 within the installation slot 21 along the second direction Y. When the external module 30 needs to be removed, the first clamping member 31 can be driven to rotate relative to the main structure 32 until the second clamping member 22 is released. Then, the main structure 32 can be slid away from the docking member to release the restraint of the external module 30 and remove the main structure 32 from the installation slot 21.

[0063] In this way, the main structure 32 can be limited and removed in the installation groove 21 by adjusting the rotation of the first clamping member 31 relative to the second clamping member 22, which is simple to operate and easy to use.

[0064] In one embodiment of the present application, referring to Figures 2 to 5 , the external module 30 is further provided with a reset member (not shown). The reset member is connected to the main structure 32 and the first engaging member 31. The reset member is used to drive the first engaging member 31 to reset and rotate, thereby engaging the first engaging member 31 with the second engaging member 22.

[0065] The reset member refers to a structural member capable of driving the first clamping member 31 to rotate to the initial state. For example, the reset member may be, but is not limited to, an elastic structure such as an elastic sheet, a spring, or an elastic rope.

[0066] The first clamping member 31 is in the initial state. The user can act on the first clamping member 31 so that the first clamping member 31 is rotated by an external force. The reset member can store energy and provide the first clamping member 31 with a force to restore to the initial state. When the external force releases the first clamping member 31, the reset member can drive the first clamping member 31 to rotate relative to the main structure 32 and clamp to the second clamping member 22.

[0067] In this way, the reset member can provide driving force for the first clamping member 31 to be clamped to the second clamping member 22, and the reset member has a simple structure. When driving the first clamping member 31 to clamp the second clamping member 22, there is no need to set up other structures for driving the first clamping member 31 to rotate, thereby saving the processing steps and design costs of the external module 30.

[0068] In one embodiment of the present application, referring to Figures 4 and 5 , a socket 213 is defined on one side of the mounting slot 21 along the second direction Y. The docking member is exposed through the socket 213. The external module 30 is configured to be plugged into the socket 213 along the second direction Y to establish electrical connection with the docking member.

[0069] The shape of the insertion hole 213 can be rectangular, circular, triangular, etc.

[0070] By providing a socket 213 on one side wall of the installation slot 21 along the second direction Y, electrical connection between the external module 30 and the docking member can be achieved. The socket 213 is easy to process, which reduces the manufacturing difficulty of the display device.

[0071] In one embodiment of the present application, referring to Figures 2 to 5 , a retaining groove 2121 is provided on the wall of the mounting slot 21 away from the opening 211 along the first direction X. The external module 30 is provided with a retaining member 33. When the external module 30 is connected to the display device 10, the retaining member 33 is retained within the retaining groove 2121 along the first direction X.

[0072] In one implementation, the limiting groove 2121 may be a groove recessed along the second direction Y. When the external module 30 is installed in the mounting groove 21 , the limiting member 33 may enter the limiting groove 2121 along the second direction Y and move within the mounting groove 21 .

[0073] It is understood that the first direction X is substantially vertical, and the external module 30 can vertically enter and exit the opening 211 of the installation slot 21. When the limiting member 33 is limited in the limiting slot 2121, the limiting member 33 can be supported by the inner wall of the limiting slot 2121 under the action of gravity.

[0074] In this way, when installing the external module 30, the limiting member 33 can be aligned with the limiting groove 2121 for installation, which provides a positioning effect for the installation of the external module 30. When the limiting member 33 is installed tilted in the limiting groove 2121, it cannot enter the limiting groove 2121, which can prevent the external module 30 from being installed tilted in the installation groove 21 as much as possible, so that the external module 30 is better aligned with the display device 10, and the electrical connection stability between the external module 30 and the display device 10 is improved.

[0075] In one embodiment of the present application, referring to Figures 2 to 5 , the limiting member 33 includes a first limiting portion 331 and a second limiting portion 332 , which are sequentially connected along the second direction Y. When the external module 30 is docked and electrically connected to the display device 10 , the first limiting portion 331 and the second limiting portion 332 elastically abut against the inner walls of the limiting groove 2121 on opposite sides along the first direction X. The first direction X and the second direction Y are perpendicular, and the second direction Y is perpendicular to the thickness direction of the display device 10 .

[0076] In one possible design, as shown in FIG4 , the second limiting portion 332 is bent from the first limiting portion 331 toward a direction away from the first limiting portion 331 along the first direction X. Alternatively, in another possible design, the first limiting portion 331 and the second limiting portion 332 are bent away from each other along the first direction X.

[0077] When installing the external module 30, because the first limiting portion 331 and the second limiting portion 332 are elastic, when entering the limiting slot 2121, the first limiting portion 331 is extended into the limiting slot 2121 along the second direction Y. The first limiting portion 331 and the second limiting portion 332 are supported by the groove wall of the limiting slot 2121 and deformed along the first direction X, thereby facilitating the first limiting portion 331 and the second limiting portion 332 to enter the limiting slot 2121. The first limiting portion 331, once inside the limiting slot 2121, elastically supports the inner wall of the limiting slot 2121 on one side along the first direction X; the second limiting portion 332, once inside the limiting slot 2121, elastically supports the inner wall of the limiting slot 2121 on the other side along the first direction X.

[0078] The first direction X is the direction X shown in FIG2 , and the second direction Y is the direction Y shown in FIG2 . The directions X and Y are perpendicular to each other, and the first direction X is perpendicular to the second direction Y. Of course, in some other implementations, the first direction X and the second direction Y may not be perpendicular.

[0079] In this way, the limiting member 33 elastically abuts against the inner walls of the limiting groove 2121 on opposite sides along the first direction X, thereby improving the secure installation of the limiting member 33 in the limiting groove 2121. Furthermore, the first limiting portion 331 and the second limiting portion 332 cooperate to improve the positioning of the external module 30 during installation, thereby minimizing the risk of tilting the external module 30 within the installation groove 21. This allows the external module 30 to be better aligned with the display device 10, thereby improving the stability of the electrical connection between the external module 30 and the display device 10.

[0080] In one embodiment of the present application, referring to FIG3 , the external module 30 is provided with a handle portion 34 . At least a portion of the handle portion 34 extends out of the opening 211 .

[0081] The handle portion 34 may be a ring-shaped structure, a rod-shaped structure, or a block-shaped structure.

[0082] During use, the user manually pushes and pulls the handle 34 , thereby providing power for the external module 30 to move within the installation slot 21 and also providing power for the external module 30 to enter and exit the opening 211 .

[0083] By providing the handle portion 34, a better fulcrum is provided for the user on the external module 30, making it easier for the user to apply force to the external module 30, thereby improving the convenience when pushing and pulling the external module 30, thereby simplifying the disassembly and assembly operations of the external module 30, and improving the convenience of repairing and replacing the external module 30.

[0084] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
