[0050] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0051] Display devices are mainly used to display image information, play video information, etc., including outdoor LED display screens, conference tablets, etc.

[0052] In the related art, some display devices with larger volumes are equipped with supporting devices and connecting devices, and the display device is mounted on the supporting device through the connecting device, so that the display device can be placed on the ground or hung on the wall through the supporting device. However, during the disassembly process, the connecting device is easy to interfere with the supporting device or the display device, making it difficult to disassemble the connecting device.

[0053] In the embodiment of the present application, by allowing the movable part of the connecting device to slide and rotate, the movable part can be flexibly moved out of position during the disassembly of the connecting device, so as to facilitate disassembly.

[0054] Please refer to Figure 1 , Figure 1 A structural schematic diagram of a display device according to an embodiment of the present application. First, an embodiment of the present application provides a connecting device 100 for connecting a display device 300 and a supporting device 200. The connecting device 100 includes a first connecting component 11, a second connecting component 12, and a movable component 13. The first connecting component 11 is used to connect and fix with one of the display device 300 and the supporting device 200. The second connecting component 12 is used to connect and fix with the other of the display device 300 and the supporting device 200. The movable component 13 is rotatably connected to the first connecting component 11 and the second connecting component 12, respectively, so that the movable component 13 can be rotated relative to the first connecting component 11 and the second connecting component 12 to an active state or a locked state.

[0055] The movable component 13 is also slidably connected to the first connecting component 11. When the movable component 13 is in an active state, the first connecting component 11 can slide relative to the movable component 13. When the movable component 13 is in a locked state, the movable component 13 can restrict the first connecting component 11 from sliding.

[0056] Please refer to Figure 1 and Figure 2 , Figure 2 for Figure 1 A structural schematic diagram of the connecting device shown. Below, taking the case where multiple groups of connecting devices 100 are installed between the supporting device 200 and the display device 300, the first connecting component 11 is connected to the display device 300, and the second connecting component 12 is connected to the supporting device 200 as an example, the working principle of the embodiment of the present application is explained and illustrated in combination with the process of the operator disassembling one group of connecting devices 100:

[0057] First, the movable part 13 of the connection device 100 to be disassembled is rotated to an active state. At this time, the movable part 13 rotates relative to the first connection part 11 and the second connection part 12 at the same time, so as to avoid the display device 300 connected to the first connection part 11 and the support device 200 connected to the second connection part 12 from restricting the rotation of the movable part 13. The display device 300 and the support device 200 are still connected and fixed by the connection devices 100 of other groups.

[0058] Then, the connection state between the first connection component 11 of the connection device 100 to be detached and the display device 300 is released.

[0059] Next, the movable component 13 is slid toward the direction close to the second connecting component 12 , thereby driving the first connecting component 11 to also be separated from the display device 300 , and further making the connecting device 100 no longer clamped between the display device 300 and the supporting device 200 .

[0060] Finally, the connection between the second connection component 12 of the connection device 100 to be disassembled and the support device 200 is released, and the connection device 100 is taken out from between the display device 300 and the support device 200 as a whole.

[0061] It can be seen that the connecting device 100 of the embodiment of the present application has the advantage of being easy to disassemble.

[0062] On the contrary, during the assembly of the connection device 100, the movable component 13 can be first slid toward the direction close to the second connection component 12, so that the entire connection device 100 is in a contracted state to be placed between the support device 200 and the display device 300. Then, the movable component 13 is slid toward the direction away from the second connection component 12 so that the movable component 13 is initially engaged between the support device 200 and the display device 300, and finally the connection between the first connection component 11 and the display device 300, the connection between the second connection component 12 and the support device 200, and the rotation of the movable component 13 to the locked state are completed in sequence.

[0063] In addition, during the installation of the connecting device 100 , after the second connecting component 12 is installed to the supporting device 200 , the first connecting component 11 can be adaptively rotated alone according to the placement posture of the display device 300 , so that the second connecting component 12 can be more accurately connected and fixed to the display device 300 .

[0064] It can be seen that the connection device 100 of the embodiment of the present application also has the advantage of being easy to assemble.

[0065] Of course, the first connecting component 11 may be used to connect the supporting device 200 , and the second connecting component 12 may be used to connect the display device 300 , which is not limited in the embodiment of the present application.

[0066] The above is an overall description of the technical solution of the embodiment of the present application. The following is an example of the technical solution of the embodiment of the present application in combination with the connection method between the movable component 13 and the second connecting component 12.

[0067] Please refer to Figure 2 and Figure 3 , Figure 3 for Figure 2A cross-sectional view of the connecting device shown. One of the second connecting component 12 and the movable component 13 is provided with a shaft body 121, and the other of the second connecting component 12 and the movable component 13 is provided with a sleeve portion 131. The sleeve portion 131 can be slidably and rotatably sleeved on the shaft body 121, so that the movable component 13 can slide and rotate relative to the first connecting component 11.

[0068] Then, the second connecting component 12 may be provided with a shaft 121, and the movable component 13 may be provided with a sleeve portion 131, so that the second connecting component 12 may be telescopically provided on the movable component 13. Alternatively, the second connecting component 12 may be provided with a sleeve portion 131, and the movable component 13 may be provided with a shaft 121. Then, it can also be understood that the movable component 13 may be telescopically provided on the second connecting component 12.

[0069] Therefore, in the actual assembly process, the sliding and rotating connection of the first connecting component 11 can be achieved by simply inserting the shaft body 121 into the sleeve portion 131, so that the second connecting component 12 has the advantages of simple structure and easy assembly.

[0070] The sleeve portion 131 may be provided with a slide groove 1311, and the shaft body 121 may be provided with a stopper 1211, and the stopper 1211 is slidably installed in the slide groove 1311. Therefore, the rotation and sliding of the movable component 13 can be guided and limited by the sliding cooperation between the slide groove 1311 and the stopper 1211, so that the rotation and sliding of the movable component 13 relative to the second connecting component 12 are more stable and reliable.

[0071] The number of the slide groove 1311 can be one. Of course, the number of the slide groove 1311 can also be multiple, such as two, three, four or five, so that the stability and reliability of the rotation and sliding of the movable part 13 relative to the second connecting part 12 are improved through the one-to-one cooperation between the multiple slide grooves 1311 and the multiple limit members 1211, which is not limited in the embodiment of the present application.

[0072] When there are multiple slide grooves 1311, the multiple slide grooves 1311 can be arranged at intervals along the circumference of the shaft body 121 or the sleeve part 131. For example, there are two slide grooves 1311, and the two slide grooves 1311 are indirectly arranged along the circumference of the shaft body 121, so as to improve the stability and reliability of the rotation and sliding of the movable part 13, and avoid the sleeve part 131 being provided with too many slide grooves 1311 to cause insufficient strength.

[0073] Exemplarily, in some embodiments, the slide groove 1311 includes a first slide groove 1311a and a second slide groove 1311b that are connected to each other. The first slide groove 1311a is extended along the axial direction of the shaft body 121, and the second slide groove 1311b is extended along the circumferential direction of the shaft body 121. When the movable part 13 is in an active state, the limiter 1211 is located in the first slide groove 1311a. When the movable part 13 is in a locked state, the limiter 1211 is located in the second slide groove 1311b.

[0074] Furthermore, the cooperation between the slide groove 1311 and the limit member 1211 can provide a good guide for the sliding and rotation of the sleeve portion 131, and the second slide groove 1311b can limit the relative sliding of the movable component 13 and the second connecting component 12, so that the display device 300 can be installed more stably.

[0075] In some embodiments, each slide groove 1311 may include a first slide groove 1311 a .

[0076] Optionally, each slide groove 1311 may also include at least two first slide grooves 1311a. For example, each slide groove 1311 includes two, three, four, five or even six first slide grooves 1311a, which is not limited in the embodiment of the present application. Thus, by sliding the stopper 1211 into different first slide grooves 1311a, the movable component 13 can move to more positions relative to the second connecting component 12 to meet more different avoidance requirements during the disassembly and assembly process of the connecting device 100, thereby improving the versatility of the connecting device 100 and the convenience during the disassembly and assembly process.

[0077] In some embodiments, each slide groove 1311 may include a second slide groove 1311b.

[0078] Optionally, each slide groove 1311 may include at least two second slide grooves 1311b. For example, each slide groove 1311 includes two, three, four, five or even six second slide grooves 1311b, which is not limited in the embodiment of the present application. Thus, by sliding the stopper 1211 into different first slide grooves 1311a, the movable component 13 can move to more positions relative to the second connecting component 12 to meet more different avoidance requirements during the disassembly and assembly process of the connecting device 100, thereby improving the versatility of the connecting device 100 and the convenience during the disassembly and assembly process.

[0079] It can be understood that when each slide groove 1311 includes at least two second slide grooves 1311b, the second slide groove 1311b of each slide groove 1311 can be arranged at axial intervals along the shaft body 121, so that by sliding the limit member 1211 into different second slide grooves 1311b, the relative position of the movable component 13 and the second connecting component 12 can be adjusted, thereby meeting the installation requirements of different spacings between the support device 200 and the display device 300.

[0080] In some embodiments, each slide groove 1311 is composed of a first slide groove 1311a and a second slide groove 1311b, thereby avoiding excessive slots on the sleeve portion 131 and reducing the overall strength of the sleeve portion 131, thereby ensuring the stability and reliability of the installation of the display device 300.

[0081] In some embodiments, the stopper 1211 may be detachable from the shaft body 121. For example, the stopper 1211 may be detachably mounted on the shaft body 121 by screw connection, clamping connection, plug-in connection, etc., which is not limited in the present embodiment.

[0082] Thus, compared with a structure in which the stopper 1211 and the shaft body 121 are integrally formed, the manufacturing difficulty of the shaft body 121 can be reduced. For example, the shaft body 121 can be conveniently formed by turning or the like.

[0083] In some embodiments, the first slide groove 1311a and the second slide groove 1311b may penetrate the inner surface and the outer surface of the sleeve portion 131. Then, in combination with the detachable connection between the stopper 1211 and the shaft body 121, the shaft body 121 may be first inserted into the sleeve portion 131 so that the shaft body 121 can be rotatably and slidably installed on the sleeve portion 131. Then, the stopper 1211 is inserted into the slide groove 1311 and connected and fixed to the shaft body 121, thereby realizing the assembly of the shaft body 121, the sleeve portion 131 and the stopper 1211.

[0084] On the contrary, the connection between the stopper 1211 and the shaft 121 can be released first, and then the stopper 1211 can be taken out of the slide slot 1311, and finally the shaft 121 can be pulled out of the sleeve 131, so as to realize the disassembly of the shaft 121, the sleeve 131 and the stopper 1211. It can be seen that the connection device 100 of the embodiment of the present application has the advantage of easy disassembly and assembly.

[0085] Please continue to refer to Figure 4 , Figure 4 for Figure 2 In some embodiments, the connecting device 100 may further include an elastic telescopic member 14. The elastic telescopic member 14 is mounted on one of the sleeve portion 131 and the shaft body 121, and abuts against the other of the sleeve portion 131 and the shaft body 121.

[0086] Therefore, during the sliding and / or rotation of the movable component 13 , the damping between the sleeve portion 131 and the shaft body 121 can be increased by the elastic telescopic member 14 , so that the movement of the sliding component is more stable.

[0087] For example, during the disassembly or assembly process, the damping applied by the elastic telescopic member 14 can make the movable component 13 more stably fixed at different positions to prevent the movable component 13 or the second connecting component 12 from shaking irregularly and affecting the operator's disassembly and assembly operations.

[0088] Of course, after the connection device 100 is assembled, the damping applied by the elastic telescopic member 14 can further limit the sliding of the movable component 13 relative to the second connection component 12, thereby improving the stability of the connection between the display device 300 and the support device 200. This embodiment of the present application does not limit this.

[0089] Exemplarily, the elastic telescopic member 14 is disposed on the shaft 121. The sleeve portion 131 is provided with a plurality of spaced limiting holes 1312. The elastic telescopic member 14 can move with the shaft 121 and be clamped to different limiting holes 1312, so that the movable component 13 can be fixed more stably at different angles and / or positions.

[0090] For example, please refer to Figure 5 , Figure 5 for Figure 2 Schematic diagram of the distribution position of the limiting holes of the connecting device shown. A plurality of limiting holes 1312 can be arranged at intervals along the extension direction of the slide groove 1311. Then, as the movable part 13 moves, when the elastic telescopic member 14 is misaligned with the limiting hole 1312, the elastic telescopic member 14 can be squeezed by the sleeve portion 131 and retracted into the mounting hole 1212; and when the elastic telescopic member 14 is facing the limiting hole 1312, the elastic telescopic member 14 can be elastically restored and thus snapped into the corresponding limiting hole 1312.

[0091] In some embodiments, the limiting hole 1312 may be a through hole, so that the processing of the limiting hole 1312 can be facilitated. For example, the limiting hole 1312 may be formed by drilling directly from the outer surface of the sleeve portion 131 .

[0092] Correspondingly, the shaft body 121 may be provided with a mounting hole 1212, so that the elastic telescopic member 14 may be mounted in the mounting hole 1212. The mounting hole 1212 may be a blind hole or a through hole, which is not limited in the embodiment of the present application.

[0093] Of course, in some other embodiments, the shaft body 121 may be provided with a plurality of limiting holes 1312 , and the sleeve portion 131 may be provided with a plurality of elastic telescopic members 14 , which is not limited in the embodiments of the present application.

[0094] In some embodiments, at least two limiting holes 1312 are spaced apart along the axial direction of the shaft body 121, so that the movable component 13 can slide until the elastic telescopic member 14 is engaged with different limiting holes 1312. Thus, the movable component 13 can be stably fixed at different positions during the sliding process.

[0095] In some embodiments, at least two limiting holes 1312 are arranged at intervals along the circumference of the shaft body 121, so that the movable component 13 can rotate until the elastic expansion member 14 is engaged with different limiting holes 1312. Thus, the movable component 13 can be fixed more stably at different positions during the rotation process.

[0096] In some embodiments, the elastic telescopic member 14 includes a ball screw. Then, when the shaft body 121 is inserted into or removed from the sleeve portion 131 , the ball screw can be adaptively compressed and deformed to facilitate the insertion and removal of the shaft body 121 .

[0097] In addition, the ball screw can also be directly threadedly connected to the shaft body 121 or the sleeve portion 131. It can be seen that the ball screw can make the elastic telescopic member 14 have the advantages of simple structure and easy disassembly and assembly.

[0098] In some embodiments, the movable component 13 is further provided with a gripping structure 132 , so as to facilitate the operator to grip the movable component 13 , so as to conveniently rotate and / or slide the movable component 13 , which is not limited in the embodiments of the present application.

[0099] The holding structure 132 may include a handle, a grip, or a contoured groove that fits with the fingers, etc., which is not limited in this embodiment of the present application.

[0100] The above are some examples of the connection between the movable component 13 and the second connection component 12 in the embodiment of the present application. Next, some examples will be given in combination with some structures of the second connection component 12.

[0101] The second connecting member 12 includes a first clamping member 122 and a second clamping member 123. The second clamping member 123 is movably mounted on a side of the first clamping member 122 away from the movable member 13, so as to cooperate with the first clamping member 122 to clamp and fix to the supporting device 200.

[0102] The first clamping member 122 can be detachably mounted on the shaft body 121. For example, the first clamping member 122 can be detachably mounted on the shaft body 121 by screw connection, clamping connection, plug-in connection, etc., which is not limited in the embodiment of the present application. Thus, the corresponding first clamping member 122 and the second clamping member 123 can be replaced according to different installation requirements of the support device 200 to improve the versatility of the connection device 100.

[0103] Exemplarily, the middle portion of the first clamping member 122 is connected and fixed to the shaft 121, and both ends of the first clamping member 122 are bent in a direction away from the movable component 13, so that the end surface of the first clamping member 122 away from the movable component 13 can abut against the column 22 of the support device 200. The second clamping member 123 is rotatably connected to one end of the first clamping member 122, so that the second clamping member 123 can be rotated to lock or release the column 22 of the support device 200.

[0104] In some embodiments, the first clamping member 122 may include a first rotating end 1221 and a first locking end 1222. The second clamping member 123 may include a second rotating end 1231 and a second locking end 1232. The first rotating end 1221 and the second rotating end 1231 are rotatably connected. One of the first locking end 1222 and the second locking end 1232 is provided with a locking structure 124, and the locking structure 124 is used to lock or release the first locking end 1222 and the second locking end 1232.

[0105] For example, the locking structure 124 includes a screw rod rotatably mounted on the first locking end 1222, and the second locking end 1232 is provided with a notch matched with the screw rod. Therefore, the screw rod can be rotated to enter the notch, and then a nut is screwed to the side of the screw rod located at the second locking end 1232 away from the first locking end 1222, thereby achieving the locking of the second locking end 1232.

[0106] The above are some examples of the second connecting component 12 in the embodiment of the present application. The following will continue to illustrate the embodiment of the present application with examples in combination with the first connecting component 11.

[0107] Please continue to refer to Figure 6 and Figure 7 , Figure 6 for Figure 3 A partial enlarged view of the X in the middle. Figure 7 for Figure 6 The first connecting member 11 includes a fixing plate 111 and a sleeve 112. The fixing plate 111 is used to be installed and fixed to the display device 300. The sleeve 112 is detachably connected to the fixing plate 111. The movable member 13 is rotatably mounted on the sleeve 112.

[0108] Therefore, when the size or shape of the display device 300 to be connected changes, it is sufficient to replace a different fixing plate 111 without remanufacturing the entire second connecting component 12 , thereby improving the versatility of the second connecting component 12 .

[0109] The shaft sleeve 112 may be detachably mounted on the fixing plate 111 by means of threaded connection, snap connection, plug-in connection, etc., which is not limited in the embodiment of the present application.

[0110] Exemplarily, the sleeve 112 may be provided with at least two threaded holes 1121 , so that a fastening screw may pass through the fixing plate 111 and then be screwed into the threaded holes 1121 of the sleeve 112 , so as to achieve threaded fixation of the sleeve 112 and the second connecting component 12 .

[0111] In some embodiments, the fixing plate 111 may be provided with a plurality of mounting holes 1111 to be mounted and fixed to the display device 300. For example, the fixing plate 111 may be square, and each corner of the fixing plate 111 may be provided with at least one mounting hole 1111, so that the fixing plate 111 may be screwed and fixed to the display device 300 by fastening screws through the mounting holes. At the same time, the fixing plate 111 may be more stably and reliably mounted to the display device 300 through the plurality of mounting holes 1111.

[0112] In some embodiments, the first connecting component 11 may further include a rotating member 113. The rotating member 113 is rotatably disposed in the shaft sleeve 112 and is connected and fixed to an end of the movable component 13 away from the second connecting component 12.

[0113] For example, the rotating member 113 may include a bolt. Therefore, in the actual assembly process, the bolt may be passed through the shaft sleeve 112 and then screwed and fixed to the movable member 13 .

[0114] In some embodiments, the rotating member 113 and the shaft sleeve 112 are clearance-fitted, so that the rotating member 113 can rotate relative to the rotating member 113 .

[0115] In some embodiments, the movable component 13 may be a rotating shaft. One end of the rotating shaft is rotatably mounted on the shaft sleeve 112, and the other end of the rotating shaft is rotatably connected to the second connecting component 12. For example, the rotating member 113, the movable component 13 and the shaft body 121 are coaxially arranged. Thus, the movable component 13 can rotate relative to the first connecting component 11 and the second connecting component 12 simultaneously around its axis. Alternatively, it can also be understood that the movable component 13 is pivotally connected between the first connecting component 11 and the second connecting component 12.

[0116] The above are some examples of the connection device 100 in the embodiment of the present application.

[0117] An embodiment of the present application further provides a display device, which may include the connection device 100 as described above.

[0118] For example, please refer to Figure 2 The display device may further include a supporting device 200 and a display device 300. The supporting device 200 is connected and fixed to the second connecting component 12. The display device 300 is connected and fixed to the first connecting component 11.

[0119] In some embodiments, the display device 300 may be a LED (Light-Emitting Diode) display screen.

[0120] Of course, the display device 300 may also be an LCD (Liquid Crystal Display) display screen or an OLED display screen (Organic Light-Emitting Diode), etc., which is not limited in the embodiment of the present application.

[0121] In some embodiments, there may be multiple display devices 300. Thus, multiple display devices 300 can be spliced ​​and fixed by the connecting device 100 and the supporting device 200, so that the display surfaces of the multiple display devices 300 are spliced ​​to form a larger total display surface.

[0122] Then, the number of the connecting device 100 may be at least one, and the first connecting component 11 of each connecting device 100 is connected and fixed to at least two display devices 300. Thus, the joints of adjacent display devices 300 can be reinforced by the first connecting component 11, so that the assembly of multiple display devices 300 is more stable and reliable.

[0123] In some embodiments, there are multiple connection devices 100 , and at least two connection devices 100 are installed on the same side of the display device 300 .

[0124] For example, the supporting device 200 may include a base 21 and a column 22 mounted on the base 21. The column 22 may be located on the side of the display device 300 away from the display surface (i.e., located on the back of the display device 300). At this time, at least two connecting devices 100 may be connected between the column 22 and the display device 300. That is, the first connecting components 11 of at least two connecting devices 100 are fixedly mounted on the display device 300, and the second connecting components 12 are fixedly mounted on the column 22, so that the connecting device 100 is installed between the column 22 and the display device 300.

[0125] Of course, in some other implementations, a connecting device 100 may also be connected between the base 21 and the display device 300 , which is not limited in the embodiment of the present application.

[0126] It can also be understood that, in the plane where the base 21 is located, the orthographic projection of the display device 300 can be at least partially located within the base 21, so that the center of gravity of the display device 300 falls as much as possible within the base 21, and thus the whole formed by the display device 300, the connecting device 100 and the supporting device 200 can be placed more stably on a supporting plane such as the ground.

[0127] Of course, in the plane where the base 21 is located, the orthographic projection of the display device 300 may also be located outside the base 21 , which is not limited in the embodiment of the present application.

[0128] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0129] The connection device 100 and the display device provided in the embodiment of the present application are introduced in detail above.
