[0068] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0069] With the development of information technology, information display and recording in multi-person interactive scenarios have become more sophisticated, especially in multi-person interactions based on multimedia systems. Each participant can centralize the content they want to display onto the multimedia system, and the multimedia system can also receive and save various information from the collaborative communication process. As mentioned in the background section, a multimedia system typically consists of display devices, stands, and functional devices.

[0070] The functional device can be a data processing unit or a power supply connection device. The data processing unit can be a device that provides data processing or computing power, such as any PC box, computing box, screen mirroring box, or TV box. The power supply connection device can be a device connected to a power source, such as any power adapter or power strip.

[0071] In related technologies, when the display device is placed on the desktop, the functional devices are often placed on or below the desktop, which takes up a lot of space and also looks cluttered, affecting the cleanliness of the meeting room or training room.

[0072] Based on the above, the applicant of this application has proposed a technical solution in the embodiments of this application. Specifically, the bracket assembly used in the multimedia system includes a bracket body, a mounting plate and a base. The bracket body is supported on the desktop by the base. The second mounting surface of the mounting plate is used to install the display device. The third mounting surface of the mounting plate is connected to the first mounting surface of the bracket body. The functional devices in the multimedia system are installed on the third mounting surface.

[0073] This setup places the functional devices on the side of the mounting plate away from the display device, reducing the space occupied by the entire multimedia system on the desktop and below it. In addition, it also hides the functional devices behind the display device, making the multimedia system visually simpler and thus improving the cleanliness of the meeting room or training room environment.

[0074] The above is the core idea of ​​this application. The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0075] An embodiment of the first aspect of this application provides a support assembly, and an embodiment of the second aspect of this application provides a multimedia system, wherein the multimedia system has the aforementioned support assembly. The solution in this application will be described in detail below using the multimedia system as an example.

[0076] As shown in Figures 1 to 4 and Figures 6 to 8, the multimedia system 10 in this embodiment includes a support assembly 300 and at least two functional devices 200. The support assembly 300 includes a support body 310, a mounting plate 320, and a base 350. The support body 310 has a first mounting surface 319, and the mounting plate 320 has a second mounting surface 3203 and a third mounting surface 3204. The second mounting surface 3203 is used to mount the display device 100, and the third mounting surface 3204 is connected to the first mounting surface 319. The support body 310 is connected to the base 350, and the base 350 is used to mount on the desktop 20. The at least two functional devices 200 are mounted on the third mounting surface 3204.

[0077] For example, the display device 100 can be a smart screen, an interactive flat panel, a monitor, or other devices. The display device 100 is connected to the support assembly 300, which provides stable support for the display device 100, thereby enabling the display device 100 to be stably placed on the desktop 20.

[0078] The bracket assembly 300 includes a bracket body 310, a mounting plate 320, and a base 350. The mounting plate 320 provides a connection, allowing the display device 100 to be connected to the bracket body 310. The bracket body 310 provides support for the display device 100. The base 350 has a relatively large bottom surface, which increases the contact area between the bracket assembly 300 and the desktop 20, thereby improving the support stability of the bracket assembly 300.

[0079] The beneficial effects of the bracket assembly 300 and the multimedia system 10 having it in the embodiments of this application are as follows:

[0080] The bracket assembly 300 includes a bracket body 310, a mounting plate 320, and a base 350. The bracket body 310 is supported on the desktop 20 via the base 350. The second mounting surface 3203 of the mounting plate 320 is used to mount the display device 100, and the third mounting surface 3204 of the mounting plate 320 is connected to the first mounting surface 319 of the bracket body 310. Thus, the bracket assembly 300 can support the display device 100 on the desktop 20. In addition, the functional device 200 in the multimedia system 10 is mounted on the third mounting surface 3204 of the mounting plate. This reduces the space occupied by the entire multimedia system 10 on the desktop 20 and the space below the desktop 20. Furthermore, it allows the functional device 200 to be concealed behind the display device 100, making the multimedia system 10 more visually concise and thus improving the cleanliness of the conference room or training room environment.

[0081] In some embodiments, the mounting plate 320 is an integral frame, and the mounting plate 320 is detachably connected to the bracket body 310.

[0082] During the installation of the display device 100 and the bracket assembly 300, the mounting plate 320 can be first removed from the bracket body 310, and then connected to the display device 100. Afterward, the entire structure consisting of the mounting plate 320 and the display device 100 can be connected to the bracket body 310. This approach provides ample operating space during the connection process, preventing the bracket body 310 from obstructing the connection.

[0083] In addition, the mounting plate 320 is an integral frame, which makes the connection process between the mounting plate 320 and the bracket body 310 less complicated, thereby improving the connection efficiency.

[0084] As shown in Figures 3 and 4, in some embodiments, the mounting plate 320 is provided with a first mounting area 3205 and a second mounting area 3206. The first mounting area 3205 is located on one side of the bracket body 310, and the second mounting area 3206 is located on the other side of the bracket body 310. A portion of the at least two functional devices 200 are mounted in the first mounting area 3205, and another portion of the at least two functional devices 200 are mounted in the second mounting area 3206; or, all functional devices 200 are mounted in either the first mounting area 3205 or the second mounting area 3206.

[0085] In other words, multiple functional devices 200 can be installed separately in the first installation area 3205 and the second installation area 3206, or they can be concentrated in one of the installation areas. Users can choose flexibly according to their own needs.

[0086] As shown in Figures 3, 4, and 10, in one embodiment, the at least two functional devices 200 include a data processing device 210 and a power connector 220. A first mounting area 3205 is provided with a first mounting part, through which the data processing device 210 is mounted in the first mounting area 3205. A second mounting area 3206 is provided with a second mounting part, through which the power connector 220 is mounted in the second mounting area 3206.

[0087] For example, the data processing device 210 may be a PC box (host box), computing box, OPS (Open Pluggable Specification) module or TV box, etc., and the user can match the corresponding data processing device 210 according to the type of display device 100.

[0088] Generally, the data processing device 210 and the power strip 220 are two essential functional devices. In this embodiment, the data processing device 210 is installed in the first installation area 3205, and the power strip 220 is installed in the second installation area 3206. This helps prevent multiple functional devices 200 from concentrating on the same side of the support body 310, which could cause the center of gravity of the multimedia system 10 to shift, thereby improving the stability of the multimedia system 10 on the desktop 20. On the other hand, both the data processing device 210 and the power strip 220 generate heat during operation; placing them in different installation areas also helps improve heat dissipation efficiency.

[0089] As shown in Figures 4, 6, and 7, in one embodiment, the first mounting part includes at least one set of first connection holes 322, and the data processing device 210 is mounted on the set of first connection holes 322 by fasteners. The second mounting part includes multiple strip holes 324, and the power terminal block 220 is fixed to some of the strip holes 324 by binding members.

[0090] For example, the fastener is a screw, and the binding is a Velcro strap or a nylon cable tie.

[0091] It is understood that a set of first connection holes 322 consists of multiple first connection holes 322 arranged in a specific manner. Different sets of first connection holes 322 have different arrangement positions or arrangements. Each set of first connection holes 322 can be matched with a certain type of data processing device 210, thus enabling the mounting plate 320 to be compatible with the installation of multiple types of data processing devices 210.

[0092] Because the data processing device 210 contains many precision components, it requires anti-shake operation after installation. In this embodiment, the data processing device 210 can be mounted to a set of first connection holes 322 using fasteners. This ensures a stable connection between the data processing device 210 and the mounting plate 320, preventing the data processing device 210 from shaking after installation and reducing the risk of collisions between the data processing device 210 and other structures.

[0093] Since the power connector 220 does not require anti-shake operation, it can be fixed to the slotted holes 324 using a binding device. Compared to screwing in screws, the binding method is simpler and improves installation efficiency. The second mounting area 3206 has multiple slotted holes 324. Some of these holes can be used with the binding device, while others can be used for heat dissipation of the display device 100. This eliminates the need to machine different types of holes, thus improving processing efficiency.

[0094] In one embodiment, the first mounting area 3205 is further provided with a plurality of heat dissipation holes 323, which may be strip-shaped holes. The heat generated by the display device 100 during operation can enter the space behind the mounting plate 320 through the heat dissipation holes 323 and then dissipate, thereby facilitating heat dissipation of the display device 100.

[0095] Of course, the heat dissipation hole 323 can also be other shapes of holes, such as square holes, circular holes, or irregular holes. In other embodiments, the heat dissipation hole can also serve as a mounting hole for installing the data processing device 210. For example, a fixing plate can be hung on the mounting plate 320 through the heat dissipation hole, and then the data processing device 210 can be mounted on the fixing plate to fix the data processing device 210 to the mounting plate 320. Alternatively, the data processing device 210 can be directly secured to the mounting plate 320 using cable ties that pass through the heat dissipation hole 323.

[0096] As shown in Figure 10, in one embodiment, the bracket body 310 is provided with a wire hole 312, and the data processing device 210 is connected to the power supply terminal block 220 through a cable 211, with the cable 211 passing through the wire hole 312.

[0097] The bracket body 310 is provided with a cable hole 312, which allows the cable 211 to extend from the first mounting area 3205 to the second mounting area 3206 through the cable hole 312, thereby connecting the data processing device 210 to the power supply board 220 through the cable 211 so that the power supply board 220 can supply power to the data processing device 210.

[0098] As shown in Figures 3 and 10, the support body 310 has a cavity 313 inside, and a through hole 314 is provided at the bottom end of the support body 310. Both the wire hole 312 and the through hole 314 are connected to the cavity 313.

[0099] Typically, the power strip 220 has a power cord 221, which extends to the outside through the cable hole 312, cavity 313, and through hole 314, so that the power cord 221 can be connected to an external power source. In addition, the power cord 221 is led out from the bottom of the bracket body 310, which also helps to avoid the visual clutter caused by the power cord 221 hanging in the air.

[0100] As shown in Figures 8 and 9, in one embodiment, the wire hole 312 is disposed on the side wall of the bracket body 310, wherein the side wall is perpendicular to the first mounting surface 319. On the one hand, since the side wall of the bracket body 31 is relatively close to the corresponding functional device 200, disposing of the wire hole 312 on the side wall of the bracket body 310 can reduce the length requirements for cables 211, power cords 221, etc. On the other hand, compared to disposing of the wire hole 312 on the front of the bracket body 310 (the side closer to the mounting plate 320), it is less likely to be obstructed during wire threading, thereby reducing the difficulty of wire threading.

[0101] As shown in Figure 10, in one embodiment, the at least two functional devices further include a power adapter 230, which is installed in the second mounting area 3206 via a second mounting part. One end of the power adapter 230 is electrically connected to the data processing device 210 via a wire hole 312, and the other end of the power adapter 230 is electrically connected to the power terminal block 220.

[0102] Some data processing devices 210 require a power adapter 230 to change the power supply voltage. Therefore, when a power adapter 230 is provided, it can be installed in the second mounting area 3206 via a second mounting part. Typically, the data processing device 210 is heavier than the power strip 220. Installing both the power adapter 230 and the power strip 220 in the second mounting area 3206 helps to further improve the weight distribution balance of the functional device 200 on both sides of the support body 310, thereby improving the stability of the multimedia system 10 on the desktop 20.

[0103] As shown in Figures 1 to 4, in some embodiments, the bracket assembly 30 further includes a decorative cover 330, which is connected to the third mounting surface 3204, and the decorative cover 330 and the third mounting surface 3204 together define an accommodating space 340, in which the functional device 200 is disposed.

[0104] The decorative cover 330 and the third mounting surface 3204 together define the receiving space 340, within which the functional device 200 is housed. This allows for the concealed installation of the functional device 200, thereby enhancing the aesthetics of the multimedia system 10. Furthermore, the decorative cover 330 also provides protection for the functional device 200, thus contributing to improved operational stability of the multimedia system 10.

[0105] In one embodiment, the top and bottom surfaces of the decorative cover 330 are respectively provided with through holes, which communicate with the receiving space for heat dissipation of the functional device 200. Alternatively, gaps are left between the top and bottom surfaces of the decorative cover 330 and the mounting plate 320 for heat dissipation of the functional device 200.

[0106] This setting helps prevent heat buildup from affecting the performance of the functional device 200.

[0107] In one embodiment, there are two decorative covers 330, located on either side of the support body 310 along a first direction parallel to the surface of the mounting plate 320 and perpendicular to the height direction of the support body 310. The two decorative covers 330, together with the mounting plate 320, define a first receiving space 340a and a second receiving space 340b. A portion of the at least two functional devices 200 are located in the first receiving space 340a, and another portion of the at least two functional devices 20 are installed in the second receiving space 340b; or all functional devices 20 are installed in either the first receiving space 340a or the second receiving space 340b.

[0108] The main body of the bracket 310 is provided with a decorative cover 330 on both sides along the first direction, which gives the multimedia system 10 a better symmetry in appearance, thereby improving the aesthetics of the multimedia system 10. In addition, when multiple functional devices 200 are distributed in the first accommodating space 340a and the second accommodating space 340b, both decorative covers 330 can serve to shield and protect the functional devices 200.

[0109] As shown in Figures 4, 5, 6, and 7, in one embodiment, the decorative cover 330 has a first side plate 331 and a second side plate 332 disposed opposite to each other, with the first side plate 331 located on the side of the second side plate 332 closer to the support body 310. The first side plate 331 is provided with a first hook 3311, and the mounting plate 320 is provided with a hanging groove 325, the first hook 3311 being adapted to the hanging groove 325; the second side plate 332 is provided with a limiting hole 333, and the side of the mounting plate 320 is provided with a limiting protrusion 326, the limiting protrusion 326 being adapted to the limiting hole 333.

[0110] When installing the decorative cover 330, first insert the limiting protrusion 326 on the side of the mounting plate 320 into the limiting hole 333 of the second side plate 332, and then hang the first hook 3311 on the first side plate 331 onto the hanging groove 325 of the mounting plate 320. Through the cooperation of the limiting protrusion 326 and the limiting hole 333, and the cooperation of the first hook 3311 and the hanging groove 325, the degree of freedom of the decorative cover 330 in the horizontal direction can be restricted, so that the decorative cover 330 can be connected to the mounting plate 320.

[0111] As shown in Figures 5 and 6, in one embodiment, the limiting hole 333 includes a first segment 3331 and a second segment 3332 that are interconnected. The first segment 3331 is located above the second segment 3332, and the average width of the first segment 3331 is smaller than the average width of the second segment 3332. The width of the first segment 3331 gradually decreases from the end closer to the second segment 3332 to the end farther away from the second segment 3332.

[0112] The second section 3332 is relatively wide, so when the decorative cover 330 is connected to the mounting plate 320, the limiting protrusion 326 can easily enter the second section 3332 of the limiting hole 333, thereby reducing the difficulty of aligning the limiting hole 333 and the limiting protrusion 326 and improving installation efficiency.

[0113] Under the influence of gravity, the limiting protrusion 326 will enter the first section 3331 of the limiting hole 333. Since the first section 3331 is relatively narrow, and its width gradually decreases from the end closer to the second section 3332 to the end farther away from the second section 3332, this helps to eliminate the gap between the limiting protrusion 326 and the limiting hole 333, ensuring that there is no significant horizontal movement space after the decorative cover 330 is connected to the mounting plate 320, thus improving the installation stability of the decorative cover 330.

[0114] As shown in Figures 4 and 6, in one embodiment, the side of the mounting plate 320 is provided with a second connecting hole 3202, and the second side plate 332 is also provided with a third connecting hole 334. The third connecting hole 334 is opposite to the second connecting hole 3202, and the second connecting hole and the third connecting hole are connected to the mounting plate by fasteners.

[0115] With this configuration, the second side plate 332 can be securely connected to the mounting plate 320 by fasteners passing through the third connecting hole 334 and the second connecting hole 3202. This restricts the vertical freedom of the decorative cover 330, thereby further improving the installation stability of the decorative cover 330. Even if it is subjected to external impact, the decorative cover 330 will not fall off the mounting plate 320.

[0116] As shown in Figures 3, 4, and 14, in some embodiments, the multimedia system 10 further includes an audiovisual device 400 and a sub-stand 500. The audiovisual device 400 has video and / or audio functions and is detachably connected to the sub-stand 500. The sub-stand 500 is mounted on the stand body 310 in a height-adjustable manner.

[0117] The audiovisual equipment 400 is mounted on the main body of the support frame 310 via a sub-stand 500. This further improves the compactness of the distribution of the various parts of the multimedia system 10, thereby reducing the space occupied on the desktop 20. Furthermore, the sub-stand 500 is mounted on the main body of the support frame 310 in a height-adjustable manner, allowing the height of the audiovisual equipment 400 to be adjusted. This makes it convenient for users to set the audiovisual equipment 400 at a suitable height according to the specific environment of the meeting room or training room.

[0118] As shown in Figures 15, 16, and 17, in one embodiment, the sub-support 500 includes a sub-support body 510 and a sub-support 520. The audiovisual device 400 is mounted on one end of the sub-support 520, and the sub-support 520 is connected to the sub-support body 510 in an angle-adjustable manner. By adjusting the angle of the sub-support 520 relative to the sub-support body 510, the angle of the audiovisual device 400 can be adjusted, thereby providing convenience for the user.

[0119] As shown in Figures 16 and 17, the sub-support 520 is further provided with a circular connecting hole 521 and an arc-shaped connecting hole 522. A screw passes through each of the circular and arc-shaped connecting holes 521 and 522, and both screws are connected to the sub-support body 510. By adjusting the position of the screw in the arc-shaped connecting hole 522, the angle of the sub-support 520 relative to the sub-support body 510 can be adjusted.

[0120] As shown in Figures 3, 6, and 7, in one embodiment, the mounting plate 320 is provided with a socket 3271, and the sub-support 500 is configured to pass through the socket 3271 from top to bottom or from bottom to top. When the sub-support 500 passes through the socket 3271 from top to bottom, the sub-support is located above the upper side of the mounting plate 320. When the sub-support 500 passes through the socket 3271 from bottom to top, the sub-support is located below the lower side of the mounting plate 320.

[0121] When the sub-bracket 500 passes through the socket 3271 from top to bottom, the sub-bracket is located above the upper side of the mounting plate 320, so that the audio-visual equipment 400 can be located on top of the display device 100 after installation (refer to Figure 1). When the sub-bracket 500 passes through the socket 3271 from bottom to top, the sub-bracket is located below the lower side of the mounting plate 320, so that the audio-visual equipment 400 can be located at the bottom of the display device 100 after installation (refer to Figure 14). Users can choose the installation position of the audio-visual equipment 400 according to their own usage needs.

[0122] As shown in Figures 3, 6 and 7, in one embodiment, the sub-support 500 is provided with at least one fourth connecting hole 501, the mounting plate 320 is provided with a strip-shaped connecting hole 328, the strip-shaped connecting hole 328 extends along the height direction of the mounting plate 320, and the sub-support 500 is fixed to the support body 310 by a connector passing through the strip-shaped connecting hole 328 and the fourth connecting hole 501.

[0123] After the sub-support 500 passes through the socket 3271, the socket 3271 can limit the horizontal movement of the sub-support 500. Based on this, the sub-support 500 can be securely connected to the mounting plate 320 via a connector passing through the strip-shaped connecting hole 328 and the fourth connecting hole 501. Furthermore, the height position of the connector in the strip-shaped connecting hole 328 can be arbitrarily selected. By selecting different height positions, different installation heights of the sub-support 500 can be achieved, thereby realizing height adjustment of the audiovisual equipment 400.

[0124] As shown in Figures 3, 8, and 10, in one embodiment, the support body 310 includes a main column 315 and a rear cover plate 316. The mounting plate 320 is connected to the main column 315. The rear cover plate 316 is detachably connected to the main column 315 to form a cavity 313 between the main column 315 and the rear cover plate 316. The main column 315 is provided with a clearance hole 318, which is opposite to the strip-shaped connecting hole 328. The connector passes through the clearance hole 318, the strip-shaped connecting hole 328, and the fourth connecting hole 501.

[0125] The main column 315 is provided with a clearance hole 318 opposite to the strip-shaped connecting hole 328. With this arrangement, when the rear cover plate 316 is removed, the strip-shaped connecting hole 328 can be exposed through the clearance hole 318, so that tools such as screwdrivers can be inserted into the cavity 313 to carry out the installation operation of the connector.

[0126] As shown in Figures 7 and 11, in some embodiments, the multimedia system 10 further includes a wall-mounting strip 120 and a display device 100. The wall-mounting strip 120 is fixedly connected to the display device 100 and is hung on the mounting plate 320. Thus, the display device 100 can be hung on the mounting plate 320 via the wall-mounting strip 120.

[0127] As shown in Figures 7 and 11, in one embodiment, the mounting plate 320 is provided with a positioning groove 329, which is located on the upper edge of the mounting plate 320, and the wall-mounting strip 120 is provided with a hook 121, which is adapted to the positioning groove 329.

[0128] The connection between the wall-mounting strip 120 and the mounting plate 320 can be achieved by the cooperation of the hook 121 and the positioning groove 329.

[0129] As shown in Figures 7, 12 and 13, in one embodiment, the wall-mounting strip 120 is further provided with a locking mechanism 122, which is located below the hook 121 and is used to engage with the lower edge of the mounting plate 320.

[0130] With this configuration, the wall-mounting strip 120 can be more securely connected to the mounting plate 320 through the coordinated action of the hook 121 and the locking mechanism 122.

[0131] As shown in Figures 12 and 13, in one embodiment, the locking mechanism 122 includes a movable hook 1221, a pull wire 1222, and a spring 1223. The movable hook 1221 is slidably connected to the wall-mounting strip 120, the pull wire 1222 is connected to the movable hook 1221, and the movable hook 1221 is also connected to the wall-mounting strip 120 via the spring 1223.

[0132] When connecting the wall-mounting strip 120 to the mounting plate 320, first pull down the pull cable 1222 to move the movable hook 1221 down. This makes it easier to engage the hook 121 of the wall-mounting strip 120 into the positioning groove 329 and to stably attach the wall-mounting strip 20 to the mounting plate 320. Then release the pull cable 1222, and the movable hook 1221 moves upward under the action of the spring 1223, thereby engaging with the lower edge of the mounting plate 320.

[0133] When it is necessary to remove the wall-mounting strip 120 from the mounting plate 320, first pull down the pull cable 1222 to separate the movable hook 1221 from the lower edge of the mounting plate 320, then lift the wall-mounting strip 120 upward to separate the hook 121 from the positioning groove 329, and then remove the wall-mounting strip 120.

[0134] As shown in Figures 6, 7, 8 and 9, in some embodiments, the mounting plate 320 is provided with a second hook 321 on the side away from the display device 100, and the bracket body 310 is provided with a hanging hole 311 on the side close to the mounting plate 320, and the second hook 321 is adapted to the hanging hole 311.

[0135] In this way, the mounting plate 320 and the bracket body 310 can be hooked together, which improves the ease of connection between the mounting plate 320 and the bracket body 310, thereby improving installation efficiency.

[0136] As shown in Figures 7, 8, and 9, in one embodiment, there are two second hooks 321. The two second hooks 321 are arranged at intervals along a first direction, which is parallel to the surface of the mounting plate 320 and perpendicular to the height direction of the bracket body 310. The bracket body 310 is provided with multiple sets of hanging holes 311 arranged along the height direction of the bracket body 310. Each set of hanging holes 311 includes two hanging holes 311 spaced apart along the first direction.

[0137] The second hook 321 has two hooks arranged at intervals, which improves the stability of the mounting plate 320 after it is connected to the bracket body 310, thus providing more stable support for the display device 100. In addition, the bracket body 310 has multiple sets of first hanging holes 311 arranged along its height. The two second hooks 321 of the mounting plate 320 can connect to any set of first hanging holes 311 on the bracket body 310. By selecting the appropriate set of first hanging holes 311, the display device 100 can be hung at different heights on the bracket body 310, allowing users to choose according to their needs. The height of the display device 100 can also be adjusted as needed during later use.

[0138] As shown in Figure 9, in one embodiment, the hanging hole 311 includes a third segment 3111 and a fourth segment 3112 that are interconnected. The third segment 3111 is located above the fourth segment 3112, and the average width of the third segment 3111 is greater than the average width of the fourth segment 3112. The width of the fourth segment 3112 gradually decreases from the end closer to the third segment 3111 to the end farther away from the third segment 3111.

[0139] The third section 3111 is relatively wide, so when the mounting plate 320 is connected to the bracket body 310, the second hook 321 can be easily inserted into the third section 3111 of the first hanging hole 311, thereby reducing the difficulty of aligning the second hook 321 with the first hanging hole 311 and improving the connection efficiency.

[0140] Under the weight of the display device 100, the second hook 321 will enter the fourth section 3112 of the first hanging hole 311. Since the fourth section 3112 is relatively narrow, and its width gradually decreases from the end closest to the third section 3111 to the end furthest from the third section 3111, this helps to eliminate the gap between the second hook 321 and the first hanging hole 311, ensuring that the display device 100 has no significant horizontal movement space after being connected to the bracket body 310, thereby improving the installation stability of the display device 100.

[0141] As shown in Figures 7 and 8, in one embodiment, the mounting plate 320 is provided with a fifth connecting hole 3201, and the bracket body 310 is provided with a sixth connecting hole 317. The mounting plate 320 is connected to the bracket body 310 through a connector passing through the fifth connecting hole 3201 and the sixth connecting hole 317.

[0142] For example, the connector can be a screw.

[0143] In addition to the mounting plate 320 being attached to the bracket body 310 via the second hook 321, the mounting plate 320 and the bracket body 310 are further connected by connectors passing through the fifth connection hole 3201 and the sixth connection hole 317. This improves the stability of the connection between the two, thereby helping to prevent the display device 100 from shaking and also preventing the display device 100 from falling off the bracket body 310 when subjected to external force, further increasing the installation stability of the display device 100.

[0148] In this embodiment, the control device 600 transmits signals to the data processing device 210 via a wiring harness 601. Based on this, the bracket body 310 has an internal cavity 313 and a wiring hole 312 connecting the cavity 313 to the accommodating space 340. A through hole 314 is located at the bottom of the bracket body 310, thus creating a wiring channel. The wiring harness 601 can extend through the through hole 314, the cavity 313, and the wiring hole 312 to the location of the data processing device 210, achieving connection with it. The through hole 314 is located at the bottom of the bracket body 310, which helps prevent the wiring harness 601 from being suspended and creating a visually cluttered appearance.

[0149] Of course, in some other embodiments, the control device 600 may also send control signals to the data processing device 210 via a wireless connection.

[0150] As shown in Figure 2, in some embodiments, the edge of the base 350 is further provided with a fixing component 360, which is used to fix the base 350 to the desktop 20. The fixing component 360 can fix the base 350 to the desktop 20, thereby further improving the support stability of the support assembly 300. Even if the support assembly 300 and the display device 100 are subjected to external forces, they can be guaranteed not to tip over, thus improving safety in use.
