[0043] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used in this specification are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0044] Reference Figures 1 to 3 The present application proposes a display device 100, which can be an interactive tablet, a touch-type multimedia display all-in-one machine, a television or a computer monitor, etc., which can display information. In the embodiment of the present application, the display device 100 includes a display screen (not shown), a back panel 10, a switching assembly 20, a guide rail 30, a computer module 40, a rear shell 50, and a power board 60.

[0045] The display screen is arranged on the front side of the back plate 10 , and the display screen includes but is not limited to an LCD display, an LED display screen, and the like.

[0046] The back plate 10 is used as a supporting body to support other components such as a display screen, wherein the front side of the back plate 10 is used to support the display screen to ensure normal display of the display screen. The back side of the back plate 10 is used for installing other components such as the adapter assembly 20, the guide rail 30, the computer module 40, the rear shell 50 and the power board 60. The back plate 10 can be made of aluminum material, so that the back plate 10 has good thermal conductivity, and no other thermal conductive material is required on the back plate 10, so that the back plate 10 has a simple structure, low cost, light weight, and is easy to carry, which is conducive to the lightweight of the back plate 10.

[0047] Combined with reference Figures 4 to 6 The function of the adapter component 20 is to convert the electric energy provided by the power source into electric energy suitable for use by the computer module 40, and provide a stable and safe power supply, thereby ensuring the normal operation and use of the computer module 40.

[0048] The two guide rails 30 are spaced apart on the back plate 10 and enclose the back plate 10 to form a guide channel 30A. The guide channel 30A can be arranged along a straight line and extend to the adapter assembly 20, and the end of the guide channel 30A away from its entrance forms a locking position 30a.

[0049] The overall outer contour of the computer module 40 can be set in a rectangular block shape, so that the opposite side of the computer module 40 can be set in a plane to better adapt to the guide rail 30. The computer module 40 is an open pluggable computer module 40 (Open Pluggable Specification, OPS). Due to the design of OPS, it can be easily inserted and unplugged from the display device 100, similar to inserting a memory card. This pluggability facilitates the maintenance and upgrade of the device. The user can replace or upgrade the OPS without replacing the entire display device 100, thereby reducing the cost and complexity of maintenance. One end of the computer module 40 is provided with a connecting terminal 411, and the computer module 40 can slide under the guiding action of the guide channel 30A so that the connecting terminal 411 is plugged into the adapter component 20 for electrical connection, which not only improves the accuracy of the docking between the connecting terminal 411 and the adapter component 20, but also improves the docking efficiency between the connecting terminal 411 and the adapter component 20.

[0050] The rear shell 50 is connected to the surface of the back plate 10 facing the guide rails 30, and the rear shell 50 covers the two guide rails 30 and the adapter assembly 20. In this way, the adapter assembly 20, the guide rails 30 and the computer module 40 are protected. The rear shell 50 is provided with an installation opening 52a, and the installation opening 52a is connected to the entrance 30b of the guide channel, so that the computer module 40 can slide into the guide channel 30A through the installation opening 52a.

[0051] The power board 60 is disposed on the back plate 10 , and the power board 60 is electrically connected to the adapter assembly 20 , so that the power board 60 supplies power to the computer module 40 through the adapter assembly 20 .

[0052] In the related art, the OPS is usually first guided to the installation position of the back panel 10 of the display device 100 by the guide rail 30, and then fixedly connected to the back panel 10 of the display device 100. However, due to assembly tolerances, the OPS interferes with the assembly constraints of the back panel 10 and the guide rail 30, respectively, which makes the installation of the OPS more difficult.

[0053] Combined with reference Figures 4 to 6 To solve the above problem, in the embodiment of the present application, the computer module 40 slides along the extension direction of the guide channel 30A, and the guide channel 30A has a locking position 30a connected to the adapter assembly 20, so that when the connection terminal 411 of the computer module 40 reaches the locking position 30a, the connection terminal 411 is electrically connected to the adapter assembly 20. That is, during the installation process of the computer module 40, the guide channel 30A formed by the guide rail 30 can correctly align the connection terminal 411 with the adapter assembly 20 for electrical connection, thereby improving the convenience of electrical conduction. At the same time, when the connection terminal 411 of the computer module 40 reaches the locking position 30a, the computer module 40 is fixedly connected to at least one guide rail 30, so that the computer module 40 only has a limiting and connection relationship with the guide rail 30, and does not need to be complicatedly assembled and fixed with other components except the guide rail 30, which simplifies the assembly process, reduces the steps and time required for assembly, and reduces the problems caused by assembly tolerances, which makes the installation of the computer module 40 easier and more convenient, and is more convenient for users to operate, thereby improving the installation efficiency of the computer module 40.

[0054] Reference Figures 4 to 6 In some structural forms, the adapter assembly 20 includes an adapter board 21 and an adapter terminal 22, wherein the adapter board 21 is disposed on the back plate 10, and the adapter terminal 22 is disposed on the side of the adapter board 21 away from the back plate 10. The adapter board 21 may be a printed circuit board (PCB), and the adapter board 21 provides corresponding interfaces with components such as a display screen and a power board 60, and the adapter board 21 is also provided with an adapter terminal 22, which is used to connect with the connection terminal 411 of the computer module 40 for electrical connection.

[0055] The computer module 40 includes a host body 41 and a connecting member 42, wherein a connecting terminal 411 is provided on one side of the host body 41, and the connecting member 42 is connected to the side of the host body 41 away from the connecting terminal 411. The connecting terminal 411 is used to dock with the adapter terminal 22. That is, a control circuit such as a control motherboard is provided inside the host body 41, so as to control the display screen after docking the connecting terminal 411 and the adapter terminal 22. The connecting member 42 is connected to the side of the host body 41 away from the connecting terminal 411, wherein the connecting member 42 can be connected to the host body 41 in a detachable manner such as a screw or a buckle, so as to facilitate subsequent disassembly, replacement and maintenance. Of course, the connecting member 42 can also be fixed to the host body 41 by welding or the like to improve the stability of the connection between the host body 41 and the connecting member 42. The connecting member 42 can be arranged in a plate shape, and the connecting member 42 is attached to the surface of the host body 41 away from the connecting terminal 411 to increase the contact area between the two, so as to improve the connection stability between the two.

[0056] When the host body 41 reaches the locked position 30a, the connection terminal 411 is connected to the adapter terminal 22, and the connection member 42 is connected and fixed to the guide rail 30, thereby ensuring the stability of the connection between the connection terminal 411 and the adapter terminal 22. When the computer module 40 needs to be replaced and repaired, the connection member 42 is disassembled from the guide rail 30, so that the connection terminal 411 and the adapter terminal 22 can be separated, thereby completing the disassembly of the computer module 40.

[0057] In addition, the computer module 40 may further include a gripping member 44, which may be connected to the surface of the connecting member 42 away from the host body 41, so that when the host body 41 slides into or out of the guide channel 30A, the user may control the connecting member 42 and the host body 41 to slide along the guide channel 30A by gripping the gripping member 44. The gripping member 44 may be specifically arranged in an inverted U-shaped rod shape, and at the same time, two or more gripping members 44 may be provided, and multiple gripping members 44 may be arranged at intervals on the connecting member 42 to provide multiple force application positions, which is more convenient for the user to operate.

[0058] Combined with reference Figure 7Further, the connecting member 42 includes an abutting portion 421 protruding from the side wall surface of the host body 41, and the guide rail 30 includes a main section 31 and a limit section 32 connected by bending, wherein the main section 31 and the limit section 32 can be an integral structure to ensure the structural stability of the guide rail 30, and specifically, the main section 31 and the limit section 32 can be formed by bending a plate-like structure to improve the preparation efficiency. A guide channel 30A is formed between the main sections 31 of the two guide rails 30, and the side wall of the host body 41 slides along the guide channel 30A under the limiting action of the guide rail 30, that is, the main section 31 is used to abut against the side wall of the limit host body 41. The limit section 32 is located at the entrance 30b of the guide channel. In this way, when the host body 41 slides in the guide channel 30A to the abutment portion 421 and abuts against the limit section 32 of the guide rail 30 located at the entrance 30b of the guide channel, the user can more intuitively know that the host body 41 is located at the locking position 30a of the guide channel 30A, that is, the connection terminal 411 of the host body 41 and the adapter terminal 22 are connected to avoid damage caused by excessive insertion of the connection terminal 411 and the adapter terminal 22. In addition, by making the limit section 32 and the abutment portion 421 located at the entrance 30b of the guide channel detachable, the connection position of the computer module 40 and the guide rail 30 is set close to the installation port 52a, so that the operator can perform assembly operations at the entrance 30b of the guide channel, so as to facilitate the early installation and later disassembly operation process of the computer module 40 and the guide rail 30, and further improve the installation efficiency of the computer module 40.

[0059] Furthermore, the limiting section 32 has a first connection hole 32a, and the abutting portion 421 has a second connection hole 421a corresponding to the first connection hole 32a. The display device 100 also includes a fastener, which passes through the second connection hole 421a and the first connection hole 32a in sequence to fix the limiting section 32 with the abutting portion 421. Among them, the first connection hole 32a and the second connection hole 421a can be threaded holes, and the fastener can be a screw. The limiting section 32 and the abutting portion 421 are fixed by screws. This fixing method is relatively simple to install and operate, has high stability, and is easy to disassemble, which is convenient for subsequent maintenance. Of course, in other embodiments, the limiting section 32 and the abutting portion 421 can also be fixed by a connection method commonly used in the art such as a pin connection or a rivet connection. It should be noted that the limiting section 32 and the abutting portion 421 can be fixed by magnetic docking or snap connection, so that the disassembly process of the two can be done without the help of other auxiliary components, so as to further improve the disassembly efficiency. The specific installation method can be selected by those skilled in the art according to specific circumstances.

[0060] Reference Figures 5 to 7In some structural forms, the computer module 40 can be fixedly connected to two guide rails 30 at the same time, so as to further improve the stability of the computer module 40 after installation. Furthermore, abutment portions 421 are provided at opposite ends of the connecting member 42, and one abutment portion 421 is detachably connected to a limiting section 32 of a guide rail 30. In this way, the abutment portions 421 at opposite ends of the connecting member 42 are respectively abutted against the limiting sections 32 of the two guide rails 30, which not only makes the overall force of the connecting member 42 balanced, but also increases the contact area of ​​the connecting member 42, so as to further improve the stability of the computer module 40 after installation.

[0061] Optionally, the guide rail 30 further includes a stopper section 33, which is bent and connected to one end of the main section 31 away from the entrance 30b of the guide channel, and is used to abut against one end of the host body 41 facing the connection terminal 411. When the host body 41 slides to the locking position 30a in the guide channel 30A, that is, the connection terminal 411 of the host body 41 and the adapter terminal 22 of the adapter board 21 are connected, the stopper section 33 abuts against one end of the host body 41 facing the connection terminal 411 to limit further sliding in the direction close to the connection terminal 411, avoid the connection terminal 411 and the adapter terminal 22 from being too deeply plugged in and causing damage, and ensure the normal service life of the computer module 40.

[0062] Combined with reference Figure 5 and Figure 8 It is understandable that, since the rear shell 50 is provided with the installation opening 52a, the structural strength of the rear shell 50 is deteriorated. Here, affected by the packaging, transportation and handling, the rear shell 50 is prone to deformation at the installation opening 52a. Thus, in some structural forms, the guide rail 30 also includes two abutment sections 35, which are respectively connected to the two opposite sides of the limiting section 32 in the thickness direction of the rear shell 50, so as to respectively abut against the two opposite inner walls of the rear shell 50 at the installation opening 52a in the thickness direction, that is, the abutment section 35 of the guide rail 30 directly contacts the inner wall surface of the rear shell 50 at the installation opening 52a, thereby effectively offsetting part of the external force to reduce the possibility of deformation of the rear shell 50, and reducing the risk of poor appearance of the display device 100 and the inability to plug and unplug the computer module 40.

[0063] Furthermore, the rear shell 50 includes a bottom plate 51 and a side plate 52 connected to each other, the side plate 52 is connected to the back plate 10, the side plate 52 cooperates with the bottom plate 51 and the back plate 10 to define a mounting cavity, and the side plate 52 is provided with a mounting opening 52a. The bottom plate 51 and the side plate 52 can be integrally formed by injection molding or the like, so as to improve the overall structural strength of the rear shell 50, or the bottom plate 51 and the side plate 52 can also be connected by screws or buckles or the like, so as to facilitate later maintenance and replacement. It should be noted that the side plate 52 can be arranged along the peripheral side of the bottom plate 51, which can not only increase the contact area between the side plate 52 and the back plate 10, thereby improving the stability of the connection between the rear shell 50 and the back plate 10, but also further improve the protective effect of the cover of the rear shell 50.

[0064] The main section 31 of each guide rail 30 is detachably connected to the surface of the back plate 10 facing the bottom plate 51, so as to improve the stability of the main section 31 of each guide rail 30 in the installation cavity, thereby improving the limiting effect of the guide rail 30 on the host body 41 of the computer module 40. Specifically, the main section 31 and the back plate 10 can be fixed by screw connection. This fixing method is relatively simple to install and operate, has high stability, and is easy to disassemble, which is convenient for subsequent maintenance. Of course, the main section 31 and the back plate 10 can also be fixed by means of clamping or the like.

[0065] Furthermore, the guide rail 30 further includes a support section 34, which is bent and connected to the side of the main section 31 away from the back plate 10, so as to abut against the surface of the bottom plate 51 facing the back plate 10. The support section 34 of the guide rail 30 abuts against the bottom plate 51 of the rear shell 50 in direct contact, thereby effectively offsetting part of the external force to reduce the possibility of deformation of the bottom plate 51 of the rear shell 50, and reducing the risk of poor appearance of the display device 100 and the risk of the computer module 40 being unable to be plugged in and out.

[0066] Reference Figures 5 to 7In some structural forms, the computer module 40 further includes an elastic buckle 43, which is connected to the connecting member 42 and at least partially protrudes from the side wall of the host body 41. The main section 31 of one of the guide rails 30 is provided with a snap-in hole 31a corresponding to the elastic buckle 43. In this way, when the host body 41 slides to the locked position 30a, the elastic buckle 43 is snap-fitted with the snap-in hole 31a to limit the sliding of the host body 41 in the guide channel 30A, thereby realizing the pre-fixation of the computer module 40 and the guide rail 30, so as to facilitate the subsequent alignment installation of the limiting section 32 of the guide rail 30 and the abutment portion 421 of the connecting member 42, thereby improving the installation accuracy and efficiency. At the same time, one end of the elastic buckle 43 protrudes from the installation opening 52a, so that when the host body 41 needs to be separated from the locking position 30a later, the user can move the one end of the elastic buckle 43 protruding from the installation opening 52a to displace the other end of the elastic buckle 43, so that the elastic buckle 43 is disengaged from the clamping hole 31a, so that the host body 41 can slide in the guide channel 30A again, and slide out of the installation opening 52a for disassembly. The elastic buckle 43 can be made of materials such as silicone or rubber.

[0067] Reference Figure 4 , Figure 5 as well as Figure 8 In some structural forms, a side wall of the computer module 40 along the sliding direction is provided with an anti-fool structure 45, and the installation opening 52a forms a matching portion 50A that matches the anti-fool structure 45. In this way, only when the anti-fool structure 45 of the computer module 40 corresponds to the position of the matching portion 50A of the back plate 10, the computer module 40 can pass through the installation opening 52a and slide into the guide channel 30A between the two guide rails 30. Therefore, by setting the anti-fool structure 45 and forming the matching portion 50A on the back plate 10, it is effectively prevented that the power module is installed upside down, so as to ensure the accuracy of the docking between the computer module 40 and the adapter terminal 22, and reduce the difficulty of assembly. Specifically, the chamfer structure can be formed at the edge of the side wall surface of the computer module 40, and the back plate 10 forms a baffle at the installation opening 52a, so that the chamfer structure of the computer module 40 is arranged opposite to the baffle, and the baffle will not block the computer module 40, so that the computer module 40 can slide smoothly into the guide channel 30A. When the chamfered structure of the computer module 40 is not directly opposite to the baffle, the baffle will block the computer module 40 so that the computer module 40 cannot slide into the guide channel 30A.

[0068] Reference Figures 5 to 7In some structural forms, the two guide rails 30 can be set separately, so that the two guide rails 30 can be disassembled and assembled separately, improving the convenience of subsequent maintenance. In some other embodiments, the display device 100 also includes a connecting plate 70, which is connected to the two guide rails 30 and located between the two guide rails 30. In this way, the two guide rails 30 are connected by the connecting plate 70 to further improve the structural strength of the two guide rails 30, thereby improving the effect of the two guide rails 30 limiting the computer module 40. At the same time, the connecting plate 70 can also carry the computer module 40 to improve the stability of the computer module 40 sliding in the guide channel 30A. It should be noted that the connecting plate 70 can be an integral structure with the two guide rails 30 to further improve the structural stability of the two guide rails 30. In addition, the adapter plate 21 can be fixed to the connecting plate 70 by screw connection or the like, so that when the connecting plate 70 is disassembled and assembled, the adapter plate 21 can be disassembled and assembled from the back plate 10 at the same time.

[0069] Furthermore, the display device 100 further includes an isolation structure 80, which is connected to the connecting plate 70 and is located between the power board 60 and the guide rail 30. The isolation structure 80 can be an integral structure with the connecting plate 70, so that by providing the isolation structure 80, physical isolation between the power board 60 and the user is achieved. This design can prevent the user from directly contacting the power board 60 during operation, reducing the risk of accidental electric shock. The user can only contact the guide rail 30 and the isolation structure 80, which effectively improves safety and meets relevant safety regulations.

[0070] Reference Figures 5 to 7 In some structural forms, the side wall of the computer module 40 is provided with a heat dissipation hole area 41a for heat dissipation, and the guide rail 30 is provided with a through hole area 31b penetrating two opposite surfaces, and the through hole area 31b is arranged opposite to the heat dissipation hole area 41a. It can be understood that a fan is arranged inside the computer module 40. When the fan inside the computer module 40 is running, the computer module 40 uses negative pressure suction to suck the air in the installation cavity through the through hole area 31b and the heat dissipation hole area 41a into the computer module 40, and the heat of the computer module 40 is taken away by convection heat dissipation, thereby achieving a cooling effect.
