[0045] For ease of display, Figure 1 and Figure 5 Only a part of the structure of the monitor 100 is shown, which is mainly used in conjunction with the plug-in device 200, and the rest of the structure is omitted.

[0046] The monitor 100 includes a platform 110, a first guide mechanism 120, and a positioning mechanism. Both the first guide mechanism 120 and the positioning mechanism are mounted on the platform 110, which provides support for the first guide mechanism 120 and the positioning mechanism. When the plug-in device 200 is in use, the plug-in device 200 is mounted on the platform 110, which also provides support for the plug-in device 200.

[0047] The plug-in device 200 includes a main body 210 in a square shape. The main body 210 houses functional units, thereby expanding the functionality of the monitor 100. The plug-in device 200 also includes a first sliding mechanism 220 and a locking mechanism 230 disposed below the main body 210. The first sliding mechanism 220 cooperates with the first guide mechanism 120, and the locking mechanism 230 cooperates with the positioning mechanism, allowing the plug-in device 200 to be installed on or removed from the monitor 100.

[0048] The plug-in device 200 may be provided with one, and the monitor 100 may be provided with a first guide mechanism 120 and a positioning mechanism. The plug-in device 200 may be installed or removed using the first guide mechanism 120 and the positioning mechanism. Multiple plug-in devices 200 may be provided, and the monitor 100 may be provided with multiple first guide mechanisms 120 and multiple positioning mechanisms. For example, if two plug-in devices 200 are provided, the monitor 100 may be provided with two first guide mechanisms 120 and two positioning mechanisms.

When removing the plug-in device 200 from the monitor 100, the user only needs to operate the locking mechanism 230 to disengage the locking mechanism 230 from the positioning mechanism. During this process, the first sliding mechanism 220 slides out of the first guide mechanism 120, and the plug-in device 200 can be successfully removed from the monitor 100. Because the plug-in device 200 is installed on the platform 110, the platform 110 provides support for the plug-in device 200, thereby ensuring the service life and reliability of the plug-in device 200. Moreover, the user only needs to operate the locking mechanism 230 to successfully install or remove the plug-in device 200, making the operation very simple.

[0050] refer to Figure 2 and Figure 4 In some specific embodiments of the present invention, the locking mechanism 230 includes:

[0051] A fixing buckle 231 provided below the main body 210;

When installing the plug-in device 200, the user lifts up the unlocking handle 233 with one hand and pushes the plug-in device 200 inward. During this process, the first sliding mechanism 220 slides into the first guide mechanism 120. When the plug-in device 200 can be pushed no further, the connector 232 engages the positioning mechanism, thereby completing the installation of the plug-in device 200 on the monitor 100. When removing the plug-in device 200, the user lifts up the unlocking handle 233 with one hand, the connecting member 232 disengages from the positioning mechanism, and then pushes the plug-in device 200 outward. During this process, the first sliding mechanism 220 slides out of the first guide mechanism 120, thereby removing the plug-in device 200 from the monitor 100.

[0056] In this embodiment, reference Figure 4 and Figure 5 If a first protrusion is formed on the connecting member 232, the positioning mechanism includes a second groove 131 provided on the platform 110, and the first protrusion is engaged with or disengaged from the second groove 131 to achieve the engagement or disengagement of the connecting member 232 with the positioning mechanism.

[0059] In this embodiment, the first sliding mechanism 220 includes a plurality of sliding sheet assemblies 221 disposed on both sides below the main body 210. For example, two sliding sheet assemblies 221 are disposed on both sides below the main body 210, for a total of four sliding sheet assemblies 221. The first guide mechanism 120 includes a first guide rail disposed on the platform 110. The first guide rail can be fixed to the platform 110 by screws. The first guide rail includes a first guide rail body 121 and a second guide rail body 122 disposed on the first guide rail body 121. The second guide rail body 122 is wider than the first guide rail body 121. A sliding groove is formed between the portion of the second guide rail body 122 that is wider than the first and second guide rail bodies and the platform 110. When installing or removing the plug-in device 200, the sliding sheet assembly 221 slides into or out of the sliding groove.

[0060] The sliding sheet assembly 221 includes a main sheet 2211 extending inward and a plurality of sliding sheets 2212 arranged on the main sheet 2211. When installing or removing the plug-in device 200, the sliding sheet assembly 221 slides in or out of the first guide mechanism 120, and the main sheet 2211 of each sliding sheet assembly 221 contacts the second guide rail body 122. The main sheet 2211 is long and has a large contact area with the second guide rail body 122, thereby ensuring the guiding effect. After the plug-in device 200 is installed on the monitor 100, even if it is subjected to external force, the second guide rail body 122 can provide a downward force for the sliding plate assembly 221 to prevent the sliding plate assembly 221 from tilting upward, thereby stably fixing the plug-in device 200; the contact area between the main plate 2211 and the second guide rail body 122 is large, which can better withstand the force of the second guide rail body 122, and the multiple sliding plates 2212 can provide support for the main plate 2211 to prevent the main plate 2211 from being damaged by excessive force; in addition, the multiple sliding plates 2212 are arranged at intervals to form gaps between each other, which can save a certain amount of material and space.

[0061] In some specific embodiments of the present invention, the first sliding mechanism 220 includes convex strips (not shown in the figure) arranged on both sides below the main body 210 and protruding inward; the first guide mechanism 120 includes a first guide rail arranged on the platform 110, the first guide rail includes a first guide rail body 121 and a second guide rail body 122 arranged on the first guide rail body 121, the second guide rail body 122 is wider than the first guide rail body 121, and a sliding groove is formed between the part of the second guide rail body 122 wider than the first guide rail body 121 and the platform 110.

[0062] In this embodiment, the first sliding mechanism 220 includes inwardly protruding ridges disposed on both sides of the lower portion of the main body 210. For example, one ridge is disposed on each side of the lower portion of the main body 210, for a total of two ridges. The first guide mechanism 120 includes a first guide rail disposed on the platform 110. The first guide rail can be fixed to the platform 110 by screws. The first guide rail includes a first guide body 121 and a second guide body 122 disposed on the first guide body 121. The second guide body 122 is wider than the first guide body 121. A slot is formed between the portion of the second guide body 122 that is wider than the first and second guide bodies and the platform 110. When installing or removing the plug-in device 200, the ridge slides into or out of the slot.

[0063] When installing or removing the plug-in device 200, the protrusion slides in or out of the first guide mechanism 120. The protrusion is long, for example, a square, and has a large contact area with the second guide rail 122, thereby ensuring effective guidance. After the plug-in device 200 is installed on the monitor 100, even if subjected to external forces, the second guide rail 122 can provide a downward force on the protrusion, preventing it from tilting upward, thereby stably securing the plug-in device 200. The large contact area between the protrusion and the second guide rail 122 can effectively withstand the forces acting on the second guide rail 122.

[0064] refer to Figure 2 In some specific embodiments of the present invention, the plug-in device 200 further includes a limiting mechanism, which includes a first limiting groove 241 provided on the first side surface 211 of the main body 210; Figure 5 The monitor 100 further includes a first surface 111 extending upward from the platform 110 , and a first limiting block 141 is provided on the first surface 111 .

[0065] In this embodiment, the limiting mechanism includes a first limiting groove 241 provided on the first side surface 211 of the main body 210. The first side surface 211 is perpendicular to the movement direction of the plug-in device 200 when installing or removing the plug-in device 200. The monitor 100 also includes a first surface 111 extending upward from the platform 110. The platform 110 and the first surface 111 are at a certain angle. For example, the platform 110 and the first surface 111 are perpendicular to each other. A first limiting block 141 is provided on the first surface 111.

[0066] When installing or removing the plug-in device 200, the first limiting block 141 engages or disengages the first limiting groove 241. After the plug-in device 200 is installed on the monitor 100, the first limiting block 141 engages with the first limiting groove 241, providing a limiting function for the limiting mechanism, that is, for the plug-in device 200, thereby preventing displacement of the plug-in device 200. For the plug-in device 200, with the locking mechanism 230 engaging with the positioning mechanism, the first sliding mechanism 220 engaging with the first guide mechanism 120, and the first limiting groove 241 cooperating with the first limiting block 141, it can be stably fixed in all dimensions, effectively preventing the plug-in device 200 from being separated from the monitor 100 due to external forces during use.

[0067] In some specific embodiments of the present invention, the limiting mechanism also includes a second limiting block (not shown in the figure) arranged on the first side surface 211 of the main body 210, and the second limiting block is spaced apart from the first limiting groove 241; a second limiting groove (not shown in the figure) is arranged on the first surface 111, and the second limiting groove is spaced apart from the first limiting block 141.

[0068] In this embodiment, the limiting mechanism further includes a second limiting block disposed on the first side surface 211 of the main body 210, and a second limiting groove is further disposed on the first surface 111 of the monitor 100. When installing or removing the plug-in device 200, the second limiting block engages or disengages the second limiting groove. After the plug-in device 200 is installed on the monitor 100, the second limiting block engages in the second limiting groove, which provides a limiting effect for the second limiting block, thereby limiting the plug-in device 200 and preventing displacement deviation of the plug-in device 200. The cooperation between the first limiting block 141 and the first limiting groove 241, and the second limiting block and the second limiting groove, forms a cross-finger-like effect, which can greatly improve the stability of the plug-in device 200. For the plug-in device 200, the locking mechanism 230 is engaged with the positioning mechanism, the first sliding mechanism 220 is engaged with the first guide mechanism 120, the first limiting groove 241 cooperates with the first limiting block 141, and the second limiting block cooperates with the second limiting groove, so that the plug-in device 200 can be stably fixed in all dimensions, thereby effectively preventing the plug-in device 200 from being separated from the monitor 100 due to external force during use.

[0069] In some specific embodiments of the present invention, the plug-in device 200 also includes a second sliding mechanism (not shown in the figure) arranged on the second side surface 212 of the main body 210; the monitor 100 also includes a second surface 112 extending upward from the platform 110, and a second guide mechanism (not shown in the figure) is provided on the second surface 112.

[0070] In this embodiment, the plug-in device 200 further includes a second sliding mechanism disposed on a second side surface 212 of the main body 210. The second side surface 212 is parallel to the direction of movement of the plug-in device 200 when installing or removing the plug-in device 200. The monitor 100 further includes a second surface 112 extending upward from the platform 110. The platform 110 and the second surface 112 form a certain angle, for example, the platform 110 and the second surface 112 are perpendicular to each other, and the second surface 112 and the first surface 111 form a certain angle, for example, the second surface 112 and the first surface 111 are perpendicular to each other. A second guide mechanism is disposed on the second surface 112. When installing or removing the plug-in device 200, the second sliding mechanism slides on or out of the second guide mechanism.

[0071] In some specific embodiments of the present invention, the second sliding mechanism includes a sliding groove recessed inward from the second side surface 212 of the main body 210 ; and the second guide mechanism includes a second guide rail provided on the second surface 112 .

[0072] In this embodiment, the sliding groove has a concave cross-section, while the second guide rail has a convex cross-section. When installing or removing the plug-in device 200, the sliding groove slides on or off the second guide rail. The second guide rail provides guidance for the sliding groove, and thus for the plug-in device 200. After the plug-in device 200 is installed on the monitor 100, the interaction between the sliding groove and the second guide rail further enhances the stability of the plug-in device 200. With the locking mechanism 230 engaging the positioning mechanism, the first sliding mechanism 220 engaging the first guide mechanism 120, and the sliding groove and the second guide rail interacting, the plug-in device 200 is stably fixed in all dimensions, effectively preventing the plug-in device 200 from being separated from the monitor 100 due to external forces during use.
