TECHNICAL FIELD

[0001] The present application relates to the technical field of display, in particular to a connecting assembly and a display device. BACKGROUND

[0002] A display screen is an electronic device widely used for displaying image content or text content. In the traditional technology, the display screen is usually locked on the mounting structure by screws. Whether it is installation or disassembly, all the screws need to be locked or removed one by one, which makes the installation process of the display module cumbersome and low in efficiency. SUMMARY

[0003] Therefore, it is necessary to provide a connecting assembly and a display device to solve the problem of cumbersome and low efficiency of the display module installation.

[0004] The present application provides a connecting assembly, which comprises:

[0005] a base frame for connecting a display module, the base frame being provided with a movable first limiting part;

[0006] a hook structure connected with the base frame and used for hanging and connecting with a mounting structure;

[0007] a pressing member movably arranged on the side of the base frame facing the mounting structure and capable of moving between a pressing position and a releasing position; the pressing member is used for pushing the mounting structure when it is in the pressing position; the pressing member is used for separating from the mounting structure when it is in the releasing position; the pressing member is provided with a second limiting part;

[0010] In one of the embodiments, a plurality of second limiting parts are arranged on the side of the pressing member facing the base frame along the reference direction.

[0011] In one of the embodiments, the second limiting part is in the form of a slot hole, the base frame comprises a connecting frame, and the first limiting part is rotatably arranged on the connecting frame to be inserted into or separated from the second limiting part.

[0012] In one of the embodiments, the first limiting part comprises:

[0013] A locking tongue rotates around the reference axis, and abuts against the second limiting portion. The locking tongue is located in front of the reference axis in the reference direction, so that the abutting member advances in the reference direction and is blocked from retreating in the reference direction.

[0014] A pushing piece is connected to the locking tongue. When the pushing piece is driven by an external force, the pushing piece can drive the locking tongue to rotate around the reference axis to a position where the locking tongue is separated from the abutting member.

[0015] In one of the embodiments, the base frame further comprises a torsion spring elastically connected between the first limiting portion and the connecting frame. The torsion spring can elastically push the first limiting portion in a direction of rotating towards the second limiting portion.

[0016] In one of the embodiments, the base frame further comprises a mounting frame. The mounting frame is provided with a receiving cavity. The connecting frame is arranged in the receiving cavity. The mounting frame comprises a base body and a side door rotatably connected to the base body. The side door is used to open and close the receiving cavity when the side door rotates, so that at least part of the structure of the first limiting portion and / or at least part of the structure of the abutting member is exposed.

[0017] In one of the embodiments, the connecting assembly further comprises a first locking member and a limiting rod. The limiting rod is connected to the base frame. The first locking member is movably arranged in the side door and can move between a locking position and an unlocking position. When the first locking member is in the locking position, the first locking member is clamped with the limiting rod, so that the side door remains in a closed state. When the first locking member is in the unlocking position, the first locking member is separated from the limiting rod, so that the side door is switched to an open state.

[0018] In one of the embodiments, the limiting rod is recessed radially inward to form a first annular groove. The first locking member comprises a through hole and a clamping hole which are in communication with each other. When the first locking member is in the locking position, the limiting rod is aligned with the through hole and is arranged at a distance from the hole wall of the through hole. When the first locking member is in the unlocking position, the limiting rod penetrates through the side door, and the hole wall of the clamping hole is clamped into the first annular groove, so that the side wall of the first annular groove abuts against the first locking member.

[0019] In one of the embodiments, a first accommodating groove is recessed on the outside of the side door. The first locking member is arranged in the first accommodating groove and is in sliding fit with the groove wall of the first accommodating groove.

[0022] In one of the embodiments, the base frame is provided with a first through hole for the insertion of the latch, the locking sheet is provided with a through hole and a clamping hole in communication with each other, the clamping hole having a smaller hole size than the through hole;

[0023] When the second locking member is in the mounting position, the through hole is aligned with the first through hole to allow the latch to pass through the locking sheet;

[0024] When the second locking member is in the fixing position, the clamping hole is aligned with the first through hole to allow the locking sheet to clamp and fix the latch.

[0025] The present application further provides a display device, which comprises a display module and the connecting assembly as described in the above embodiments, the display module being detachably mounted on the connecting assembly, and the connecting assembly being used for detachably connecting to the mounting structure.

[0026] The hook structure is connected with the base frame and used for hanging connection with the mounting structure. By driving the abutting member to move to the abutting position, the abutting member abuts against the mounting structure at the hanging connection position of the hook structure and the mounting structure, so that the interaction force at the hanging connection position of the hook structure and the mounting structure can be improved. Therefore, the connection assembly can be tightly hung and connected with the mounting structure, and the stability of the connection between the connection assembly and the mounting structure is improved. In addition, the first limiting part is limited by the second limiting part, so that the position of the abutting member can be limited. In this way, the abutting member can be kept at the abutting position by the limiting action of the first limiting part, so that the hook structure and the mounting structure can be kept in tight hanging connection. When the connection assembly is connected with the mounting structure, after the hook structure and the mounting structure are hung, the abutting member and the first limiting part are driven to move to the corresponding positions, so that the hook structure and the mounting structure can be tightly hung and connected. In this way, the connection efficiency of the connection assembly and the mounting structure can be improved, and the connection between the connection assembly and the mounting structure has high stability.

[0047] Referring to Figure 1 , Figure 1 A side view of a display device in an embodiment of the present application is shown when the display device is mounted on a mounting structure. The display device 1 provided by an embodiment of the present application includes a display module 20 and a connecting assembly 10, the display module 20 is mounted on the connecting assembly 10, and the connecting assembly 10 is used to be detachably connected to the mounting structure 30. The display device 1 is connected between the display module 20 and the mounting structure 30 by the connecting assembly 10, so that the efficiency of dismounting and mounting the display device 1 can be improved.

[0048] Referring to Figure 1 and Figure 2 In an embodiment, the connecting assembly 10 includes a base frame 100, a hook structure 200 and an abutting member 300, the base frame 100 is used to connect the display module 20. The hook structure 200 is connected to the base frame 100 and is used to be connected to the mounting structure 30 by hooking. The abutting member 300 is movably arranged on the side of the base frame 100 facing the mounting structure 30 and can move between an abutting position and a releasing position. The abutting member 300 is used to abut the mounting structure 30 at the hooking connection between the hook structure 200 and the mounting structure 30 when the abutting member 300 is in the abutting position; the abutting member 300 is used to separate from the mounting structure 30 when the abutting member 300 is in the releasing position. The base frame 100 is provided with a movable first limiting portion 1110, and the abutting member 300 is provided with a second limiting portion 310, the first limiting portion 1110 can move to a position in limiting cooperation with the second limiting portion 310, and the first limiting portion 1110 can move to a position separated from the abutting member 300.

[0049] The hook structure 200 is connected with the base frame 100 and used to be hung and connected with the mounting structure 30. By driving the abutting member 300 to move to the abutting position, the abutting member 300 pushes the mounting structure 30 at the hung and connected position (hereinafter referred to as the hung and connected position K) of the hook structure 200 and the mounting structure 30, so that the interaction force at the hung and connected position of the hook structure 200 and the mounting structure 30 can be improved. Thus, the connection assembly 10 can be tightly hung and connected with the mounting structure 30 through the hook structure 200, and the stability of the connection between the connection assembly 10 and the mounting structure 30 is improved. Moreover, the first limiting part 1110 can limit the position of the abutting member 300 through limiting cooperation with the second limiting part 310. In this way, the abutting member 300 can be kept at the abutting position through the limiting action of the first limiting part 1110, so that the hook structure 200 and the mounting structure 30 can be kept tightly hung and connected. When the connection assembly 10 is connected with the mounting structure 30, after the hook structure 200 is hung and connected with the mounting structure 30, the abutting member 300 and the first limiting part 1110 can be driven to move to the corresponding positions, so that the hook structure 200 and the mounting structure 30 can be tightly hung and connected. In this way, the efficiency of the connection between the connection assembly 10 and the mounting structure 30 can be improved, and the connection between the connection assembly 10 and the mounting assembly has higher stability.

[0050] When disassembly is needed, the first limiting part 1110 can be driven to move to a position separated from the second limiting part 310 to provide a moving space for the abutting member 300, so that the abutting member 300 can move to the loosening position. Thus, the mounting structure 30 and the hook structure 200 have a moving space for separating the mounting structure 30 from the hook structure 200 at the hung and connected position K, so that the disassembly can be completed.

[0051] Further, the abutting member 300 and the hook structure 200 are arranged on the base frame 100, so that the connection assembly 10 does not need additional parts to be connected with the mounting structure 30. In this way, the portability of the connection assembly 10 is improved, and the connection assembly 10 can be conveniently transported to the installation site. Meanwhile, for the display device 110 which needs to be installed in a high-altitude environment (such as a building curtain wall), since the connection assembly 10 and the mounting structure 30 are connected and installed without additional parts, the probability of safety accidents such as falling of scattered parts in the high-altitude environment can be reduced.

[0052] Please refer to Figure 1 It can be understood that the hung and connected position K is located at the end of the hook structure 200 away from the base frame 100, and the abutting member 300 can be inserted at the region of the hook structure 200 close to the base frame 100. In short, the abutting member 300 and the hung and connected position K are distributed in the regions near the two opposite ends of the hook structure 200, so as to facilitate the abutting member 300 to push the mounting structure 30 at the hung and connected position K.

[0053] Please continue to refer toFigure 1 In one embodiment, the hook structure 200 includes two hooks 210, each of which is connected to the base frame 100 and is hung on the opposite side of the mounting structure 30, so as to improve the balance of the hook structure 200. The abutting member 300 can be located between the two hooks 210, so as to uniformly provide the abutting force to the hooking positions K of the two hooks 210.

[0054] Referring to Figure 2 In one embodiment, the abutting member 300 moves along the reference direction S from the loosening position to the abutting position. Along the reference direction S, the thickness of at least a part of the abutting member 300 gradually decreases. That is, along the reference direction S, the thickness of the front side region of the abutting member 300 is relatively small, and the thickness of the rear side region is relatively large. By adjusting the displacement distance of the abutting member 300 along the reference direction S, the regions of different thicknesses of the abutting member 300 can be correspondingly abutted between the base frame 100 and the mounting structure 30, so as to adjust the degree of the abutting member 300 providing the abutting force to the hooking position K, i.e., to adjust the abutting force of the abutting member 300.

[0055] Referring to Figure 2 and Figure 3 In one embodiment, a plurality of second limiting portions 310 are arranged on the side of the abutting member 300 facing the base frame 100 along the reference direction S. Thus, as the abutting member 300 moves along the reference direction S, the first limiting portion 1110 can be limitedly matched with the second limiting portion 310 at different positions, so as to stably limit the abutting member 300 at different positions providing different abutting forces. In this way, the abutting member 300 can stably provide a plurality of adjustable abutting forces, so as to meet different connection and installation requirements.

[0056] In one embodiment, the abutting member 300 has the elastic deformability. Thus, on the one hand, the abutting member 300 is facilitated to be filled and abutted between the base frame 100 and the mounting structure 30. On the other hand, the connection assembly 10 has a certain anti-vibration property, i.e., the probability of the abutting member 300 loosening under the vibration is reduced.

[0057] In one embodiment, the abutting member 300 can be made of materials such as silica gel and rubber having the elastic deformability. In this embodiment, the abutting member 300 is made of silica gel and rubber, so that the abutting member 300 also has a large static friction coefficient, so as to further improve the position stability of the abutting member 300.

[0058] Referring to Figure 3The abutting member 300 is not limited to be designed as a whole thickness decreasing in one direction. For example, in an embodiment, the abutting member 300 can include an abutting section 320 and a contacting section 330. The thickness of the abutting section 320 gradually increases along the reference direction S, and the thickness of the contacting section 330 is constant and equal to the maximum thickness of the abutting section 320. In this way, the abutting force of the abutting member 300 can be adjusted by the thickness variation design of the abutting section 320, and the contact range with the mounting structure 30 can be increased and the position stability of the abutting member 300 can be improved by the constant thickness design of the contacting section 330.

[0059] Please continue to refer to Figure 3 In an embodiment, the side of the abutting member 300 away from the base frame 100 is provided with an adaptive groove 331, the shape of the adaptive groove 331 is adapted to the shape of the side of the mounting structure 30 facing the base frame 100, so as to increase the contact area of the abutting member 300 with the mounting structure 30, and the abutting member 300 can more stably provide the abutting force to the mounting structure 30.

[0060] Please refer to Figure 4 In an embodiment, the base frame 100 includes a connecting frame 1100, and the abutting member 300 is movably arranged in the connecting frame 1100. The connecting frame 1100 is provided with a limiting slide 1120 extending along the reference direction S. The connecting assembly 10 further includes a connecting member 600, one end of the connecting member 600 abuts the side of the connecting frame 1100 away from the abutting member 300, and the other end of the connecting member 600 penetrates through the limiting slide 1120 and is connected with the abutting member 300. In this way, the limiting slide 1120 can limit the movement range of the connecting member 600, and the abutting member 300 can be stably positioned within a certain range relative to the connecting frame 1100 by limiting the connecting member 600, so as to improve the portability of the connecting assembly 10.

[0061] Please refer to Figure 3 and Figure 4 In an embodiment, the second limiting part 310 is in the shape of a slot hole, and the first limiting part 1110 is rotatably arranged in the connecting frame 1100 to be inserted into or separated from the second limiting part 310. In this way, the abutting member 300 can be locked or released by driving the first limiting part 1110 to rotate.

[0062] Please continue to refer to Figure 3 and Figure 4In one embodiment, the first limiting part 1110 comprises a lock tongue 1111, a push piece 1112 and a torsion spring 1113. The lock tongue 1111 is arranged on the connecting frame 1100 and rotates around the reference axis O. The lock tongue 1111 abuts against the second limiting part 310. The lock tongue 1111 is located in front of the reference direction S relative to the reference axis O, so as to allow the abutting piece 300 to move forward along the reference direction S and block the abutting piece 300 from moving backward along the reference direction S. It can be understood that, in this embodiment, the lock tongue 1111 and the abutting piece 300 can form a cooperation mode similar to a ratchet mechanism. The lock tongue 1111 can be regarded as a pawl, the abutting piece 300 can be regarded as a ratchet wheel, and the second limiting part 310 can be regarded as a tooth groove of the ratchet wheel. When the abutting piece 300 moves along the reference direction S, the side wall of the second limiting part 310 can push the lock tongue 1111 to rotate around the reference axis O to the O1 direction, so that the lock tongue 1111 is clamped into the next second limiting part 310. When the abutting piece 300 moves in the direction opposite to the reference direction S, the lock tongue 1111 abuts against the side wall of the second limiting part 310 to block the movement of the abutting piece 300.

[0063] In combination Figure 4 The push piece 1112 is connected with the lock tongue 1111. When the push piece 1112 is driven by an external force, the push piece 1112 can drive the lock tongue 1111 to rotate around the reference axis O to a position separated from the abutting piece 300, i.e., to rotate in the O1 direction. Thus, the lock tongue 1111 can be separated from the side wall of the second limiting part 310 by the push piece 1112, so as to facilitate the movement of the abutting piece 300 in the direction opposite to the reference direction S to the loosening position.

[0064] In combination Figure 4 The torsion spring 1113 is elastically connected between the first limiting part 1110 and the connecting frame 1100. The torsion spring 1113 can elastically push the first limiting part 1110 in the direction close to the second limiting part 310. In this way, when the abutting piece 300 moves along the reference direction S, and the lock tongue 1111 is switched from the position aligned with one of the second limiting parts 310 to the position aligned with the next second limiting part 310, the lock tongue 1111 can be accurately clamped into the next second limiting part 310 in the O2 direction around the reference axis O under the action of the torsion spring 1113, thereby reducing the probability of the occurrence of the situation that the lock tongue 1111 abuts incorrectly.

[0065] It should be noted that the limiting cooperation mode of clamping by the lock tongue 1111 and the second limiting part 310 in the form of a groove is not limited in the present application. For example, the first limiting part 1110 and the second limiting part 310 can also adopt a limiting part mode of inserting a shaft hole or a limiting mode of clamping.

[0066] Please refer to Figure 1 and Figure 4In one embodiment, the base frame 100 further comprises a mounting frame 1200 connected with the connecting frame 1100. The mounting frame 1200 is provided with a receiving cavity 1201, and the connecting frame 1100 is arranged in the receiving cavity 1201. Since the first limiting part 1110 is arranged in the connecting frame 1100, the first limiting part 1110 is also located in the receiving cavity 1201. Similarly, the abutting member 300 is also arranged in the connecting frame 1100, i.e. the abutting member 300 is also located in the receiving cavity 1201. Thus, by the isolation effect provided by the mounting frame 1200, the negative influence of the interference factors possibly existing in the external environment on the positions of the first limiting part 1110 and the abutting member 300 can be reduced, so as to relatively improve the stability of the positions of the first limiting part 1110 and the abutting member 300.

[0067] Please refer to Figure 1 , Figure 2 and Figure 5 In one embodiment, the mounting frame 1200 comprises a base body 1210 and a side door 1220 rotationally connected with the base body 1210. When the side door 1220 is rotated, the receiving cavity 1201 is opened and closed, so that at least part of the structure of the first limiting part 1110 and / or at least part of the structure of the abutting member 300 can be exposed. Thus, by opening the side door 1220, the first limiting part 1110 can be conveniently driven to move, so that the first limiting part 1110 is separated from the second limiting part 310; and by opening the side door 1220, the abutting member 300 can be conveniently driven to move to the loosening position when the first limiting part 1110 is separated from the second limiting part 310, so as to facilitate the disassembly of the connecting assembly 10.

[0068] Please refer to Figure 5 The push piece 1112 is located on the side of the connecting frame 1100 facing the side door 1220, so that when the side door 1220 is opened, the push piece 1112 can be used to conveniently drive the lock tongue 1111 to rotate.

[0069] Please refer to Figure 6 to Figure 8 In one embodiment, the connecting assembly 10 further comprises a first locking member 400 and a limiting rod 500, and the limiting rod 500 is connected with the base frame 100. The first locking member 400 is movably arranged in the side door 1220 and can move between a locking position and an unlocking position. When the first locking member 400 is in the locking position, the first locking member 400 is clamped with the limiting rod 500, so that the side door 1220 remains in a closed state; when the first locking member 400 is in the unlocking position, the first locking member 400 is separated from the limiting rod 500, so that the side door 1220 can be switched to an open state. Thus, by controlling the first locking member 400 to switch to different cooperation with the limiting rod 500, the locking and unlocking of the side door 1220 can be realized, so as to simultaneously improve the stability of the side door 1220 in the closed state and the convenience of opening. Figure 7 The first locking member 400 is shown in the locking position; Figure 8The first locking member 400 is shown in the unlocked position.

[0070] Please refer to Figure 4 and in combination with Figure 7 and Figure 8 In one embodiment, the limiting rod 500 is recessed radially inward to form a first annular groove 510. The first locking member 400 includes a through hole 410 and a clamping hole 420 which are in communication with each other. When the first locking member 400 is in the locked position, the limiting rod 500 is aligned with the through hole 410 and is spaced apart from the hole wall of the through hole 410, so that the limiting rod 500 can be easily inserted into and pulled out of the through hole 410, that is, the limiting rod 500 and the first locking member 400 do not form a limiting fit at this time. When the first locking member 400 is in the unlocked position, the limiting rod 500 penetrates the side door 1220, and the hole wall of the clamping hole 420 is clamped into the first annular groove 510, so that the side wall of the first annular groove 510 abuts against the first locking member 400. It can be understood that when the hole wall of the clamping hole 420 is clamped into the first annular groove 510, the part of the first locking member 400 located beside the clamping hole 420 will abut against the side wall of the first annular groove 510, so that the first locking member 400 and the limiting rod 500 form a clamping limiting fit. Since the first locking member 400 is arranged on the side door 1220, and the limiting rod 500 is arranged on the base frame 100, when the first locking member 400 and the limiting rod 500 are clamped and fitted, the side door 1220 can be limited relative to the base frame 100, that is, the side door 1220 remains in the closed state.

[0071] Please refer to Figure 7 and Figure 8 It is easy to understand that the inner diameter of the clamping hole 420 is smaller than the inner diameter of the through hole 410, so that when the through hole 410 is aligned with the limiting rod 500, the limiting rod 500 can be freely inserted and pulled out; and when the clamping hole 420 is aligned with the limiting rod 500, the inner peripheral wall of the clamping hole 420 can be clamped into the first annular groove 510.

[0072] Please refer to Figure 4 In one embodiment, the limiting rod 500 can be arranged on the connecting frame 1100.

[0073] Please refer to Figure 6 to Figure 8 In one embodiment, a first accommodating groove 1221 is recessed on the outside of the side door 1220, and the first locking member 400 is arranged in the first accommodating groove 1221 and is in sliding fit with the groove wall of the first accommodating groove 1221. In this way, the accommodating isolation effect provided by the groove wall of the first accommodating groove 1221 can reduce the influence of the outside environment on the position of the first locking member 400, and improve the position stability of the first locking member 400.

[0074] Please continue to refer to Figure 7 and Figure 8In one embodiment, the first locking member 400 is provided with a first positioning portion 1222 on one of the side doors 1220, and provided with a first limiting structure 430 on the other side door 1220. The first limiting structure 430 includes a first stop portion 431 and a second stop portion 432. The first positioning portion 1222 is in limiting cooperation with the first stop portion 431 to limit the first locking member 400 in the locked position. The first positioning portion 1222 is in cooperation with the second stop portion 432 to limit the first locking member 400 in the unlocked position. Thus, through the limiting actions of the first stop portion 431 and the second stop portion 432 on the first positioning portion 1222, the first locking member 400 can be stably positioned in the locked position and the unlocked position.

[0075] In one embodiment, the first positioning portion 1222 can be partially spherical. The first limiting structure 430 further has a first sliding channel 433 connecting the first stop portion 431 and the second stop portion 432. The width of the first sliding channel 433 is smaller than the inner diameter of the first stop portion 431 and the inner diameter of the second stop portion 432, and is also smaller than the maximum outer diameter of the first positioning portion 1222. When the first locking member 400 moves between the unlocked position and the locked position, the first positioning portion 1222 partially penetrates into the first sliding channel 433. In this way, the situation that the first positioning portion 1222 excessively lifts the first locking member 400 when the first locking member 400 moves between the unlocked position and the locked position can be reduced. Moreover, the first positioning portion 1222 partially penetrates into the first sliding channel 433, rather than completely penetrating into the first sliding channel 433. Thus, when the first positioning portion 1222 slides into the first stop portion 431 or the second stop portion 432, the first positioning portion 1222 can be stably positioned in the first stop portion 431 or the second stop portion 432 without external force, so as to stably position the first locking member 400 in the unlocked position and the locked position.

[0076] In one embodiment, the abutting member 300 and the hook structure 200 can be multiple. The multiple hook structures 200 are all used to be connected with the mounting structure 30 by hooking, so as to realize multi-point connection and improve the stability of the connection. The multiple abutting members 300 are arranged in one-to-one correspondence with the multiple hook structures 200, so as to provide abutting force to the corresponding hook structure 200.

[0077] Please refer to Figure 9 and Figure 10 In one embodiment, the display module 20 can be detachably mounted on the connecting assembly 10. For example, the connecting assembly 10 can be detachably mounted on the mounting rack 1200.

[0078] Please refer to Figure 9 and Figure 10In one embodiment, the connecting assembly 10 further comprises a second locking member 700, and the base frame 100 is configured to allow the latch 21 of the display module 20 to pass through. The second locking member 700 comprises a locking piece 710 and an operating portion 720 connected with each other. The second locking member 700 is movably arranged in the base frame 100 and can move to a mounting position and a fixing position. When the second locking member 700 is in the fixing position, the locking piece 710 is configured to be engaged with the latch 21. When the second locking member 700 is in the mounting position, the locking piece 710 is configured to be disengaged from the latch 21. Thus, by inserting the latch 21 into the base frame 100 and driving the second locking member 700 to the fixing position, the latch 21 can be engaged with the second locking member 700, and the display module 20 can be fixed relative to the base frame 100.

[0079] As mentioned above, the second locking member 700 can be movably arranged in the mounting frame 1200, and the latch 21 can be inserted into the mounting frame 1200 and engaged with the second locking member 700 in the fixing position.

[0080] When the connecting assembly 10 is connected with the display module 20, the mounting frame 1200 can be engaged with the latch 21 by inserting the latch 21 into the base frame 100 and driving the second locking member 700 to the fixing position. Thus, the convenience of connecting the connecting assembly 10 with the display module 20 can be improved. Moreover, no additional parts are needed for connecting and mounting the connecting assembly 10 with the display module 20, so that the connecting assembly 10 and the display module 20 can be conveniently transported to the installation site. Meanwhile, for the display device 1 which needs to be installed in a high-altitude environment (such as a building curtain wall), since no additional parts are needed for connecting and mounting the connecting assembly 10 with the display module 20, the probability of safety accidents such as falling of scattered parts in the high-altitude environment can be reduced.

[0081] The connecting assembly 10 is thus configured, so that the connection and mounting between the connecting assembly 10 and the display module 20, and the connection and mounting between the connecting assembly 10 and the mounting structure 30 are simple, efficient and do not need additional parts. Thus, the installation of the display device 1 comprising the connecting assembly 10 can be more simple and efficient.

[0082] Please continue to refer to Figure 10 In one embodiment, the locking piece 710 is arranged in the base frame 100, and the operating portion 720 is exposed outside the base frame 100. Thus, the second locking member 700 can be conveniently driven as a whole to move between the mounting position and the fixing position outside the base frame 100 by the operating portion 720. Thus, the front installation and side installation of the display module 20 can be conveniently realized. In other words, the convenience of installing the display module 20 in the base frame 100 can be improved by such a configuration.

[0083] Specifically, the locking piece 710 can be arranged in the mounting frame 1200, and the operating portion 720 can be exposed outside the mounting frame 1200.

[0084] Please refer to Figure 10 to Figure 13In one embodiment, the base 100 is provided with a first through hole 1211a for the insertion of the pin 21, and the locking piece 710 is provided with a through hole 711 and a clamping hole 712 which are in communication with each other, and the clamping hole 712 has a smaller hole size than the through hole 711. As shown in Figure 12 Fig. 2, when the second locking member 700 is in the installation position, the through hole 711 is aligned with the first through hole 1211a and used for the pin 21 to penetrate the locking piece 710. It can be understood that at this time, the pin 21 can be freely inserted or pulled out of the through hole 711, so as to facilitate disassembly and installation. As shown in Figure 13 Fig. 3, when the second locking member 700 is in the fixed position, the clamping hole 712 is aligned with the first through hole 1211a, so that the locking piece 710 is clamped and fixed with the pin 21. In this way, through the clamping and limiting of the pin 21 by the locking piece 710, the display module 20 as a whole can be fixed relative to the connecting assembly 10.

[0085] Please refer to Figure 10 In one embodiment, the base body 1210 of the mounting bracket 1200 is provided with a mounting wall 1211, and the first through hole 1211a can be formed in the mounting wall 1211.

[0086] In combination with Figure 11 When the through hole 711 is aligned with the first through hole 1211a, the pin 21 can not be in contact with the hole wall of the through hole 711, so there is no interaction force between them. When the clamping hole 712 is aligned with the first through hole 1211a, the structure of the locking piece 710 located beside the clamping hole 712 will be clamped with the pin 21 to form clamping and limiting fixation.

[0087] Please refer to Figure 11 to Figure 13 In one embodiment, the mounting bracket 1200 is provided with a sliding rail 1230 located in the accommodating cavity 1201, and the locking piece 710 is in sliding cooperation with the sliding rail 1230, so that the sliding rail 1230 can guide and limit the movement of the locking piece 710 relative to the mounting bracket 1200. The sliding rail 1230 is provided with a second through hole 1231, and the second through hole 1231 is coaxially arranged with the first through hole 1211a, that is, the projection of the first through hole 1211a on the sliding rail 1230 coincides with the second through hole 1231. The pin 21 penetrates the first through hole 1211a and the second through hole 1231 in sequence to reach the accommodating cavity 1201. Please refer to Figure 12 , Figure 12 Fig. 4, when the second locking member 700 is in the installation position, the through hole 711 is aligned with the first through hole 1211a, that is, the through hole 711 is aligned with the second through hole 1231, and the pin 21 penetrates the first through hole 1211a, the second through hole 1231 and the through hole 711 in sequence. Please refer to Figure 13 , Figure 13The second locking member 700 is shown in the fixed position, in which the card hole 712 is aligned with the first through hole 1211a, i.e. the card hole 712 is aligned with the second through hole 1231, and the plug 21 passes through the first through hole 1211a, the second through hole 1231 and the card hole 712 in sequence.

[0088] Please continue to refer to Figure 11 to Figure 13 In one embodiment, the plug 21 is circumferentially recessed with a second ring groove 21a, and when the second locking member 700 moves to the fixed position, the hole wall of the card hole 712 can be clamped into the second ring groove 21a, and the structure of the locking piece 710 beside the card hole 712 can abut against the side wall of the second ring groove 21a. Thus, the plug 21 can be locked with the mounting rack 1200 by the locking piece 710, so that the display module 20 can be stably mounted on the mounting rack 1200.

[0089] In one embodiment, the hole diameter of the first through hole 1211a and the hole diameter of the second through hole 1231 can be equal and equal to the outer diameter of the plug 21. The hole diameter of the through hole 711 can be equal to or greater than the hole diameters of the first through hole 1211a and the second through hole 1231. The plug 21 is provided with a neck 21b surrounded by the second ring groove 21a, and the hole diameter of the card hole 712 is smaller than the outer diameter of the plug 21 and greater than the outer diameter of the neck 21b, so that when the second locking member 700 is in the fixed position, the hole wall of the card hole 712 can be clamped into the second ring groove 21a, and the structure of the locking piece 710 beside the card hole 712 can abut against the side wall of the second ring groove 21a.

[0090] Of course, in other embodiments, the plug 21 can also be clamped with the locking piece 710 in other forms. For example, a limiting groove (not shown) can be formed on the circumferential surface of the plug 21. When the locking piece 710 is in the fixed position, the locking piece 710 is clamped and fixed with the limiting groove, so that the plug 21 can be fixed relative to the mounting rack 1200. When the locking piece 710 is in the mounting position, the locking piece 710 is separated from the plug 21, so as to facilitate the plug 21 to be inserted into or pulled out of the mounting rack 1200.

[0091] Please refer to Figure 11 In one embodiment, the inner wall of the mounting rack 1200 and one of the second locking member 700 are provided with a second limiting structure 713, and the other is provided with a second positioning portion 1242. In combination with Figure 12The second limiting structure 713 includes a third stop portion 713a and a fourth stop portion 713b. The second positioning portion 1242 is in limiting cooperation with the third stop portion 713a to limit the lock piece 710 in the installation position, and the second positioning portion 1242 is in limiting cooperation with the second limiting portion 310 to limit the lock piece 710 in the fixed position. In this way, the lock piece 710 can be stably in the installation position and the fixed position by the cooperation of the second positioning portion 1242 with the third stop portion 713a and the second limiting portion 310 respectively, so as to reduce the probability that the lock piece 710 is displaced due to external factors such as vibration and causes the bolt 21 to be loose.

[0092] Please refer to Figure 12 and Figure 13 In an embodiment, the mounting structure 30 further includes a positioning member 1240 embedded in the slide rail 1230. The positioning member 1240 includes a body 1241 and a second positioning portion 1242 as described above. The third stop portion 713a and the fourth stop portion 713b are in the form of a slot hole in the lock piece 710, and the second positioning portion 1242 is in the form of a partial spherical protrusion in the body 1241 and faces the lock piece 710. The second positioning portion 1242 can be inserted into the third stop portion 713a and the fourth stop portion 713b to abut the hole wall of the third stop portion 713a and the fourth stop portion 713b to form limiting cooperation. In this way, the lock piece 710 can be stably in the installation position when the second positioning portion 1242 is inserted into the third stop portion 713a, and the lock piece 710 can be stably in the fixed position when the second positioning portion 1242 is inserted into the fourth stop portion 713b.

[0093] Further, since the second positioning portion 1242 is in the form of a partial sphere, when the second positioning portion 1242 is inserted into the third stop portion 713a and the fourth stop portion 713b, a slight vibration will be generated, which will be fed back to the operator through the lock piece 710 and the operation portion 720, so as to facilitate the operator to know whether the lock piece 710 is moved to the position.

[0094] Please refer to Figure 11 to Figure 13In one embodiment, the second limiting structure 713 further has a second sliding channel 713c connecting the third stop portion 713a and the fourth stop portion 713b, the width of the second sliding channel 713c is smaller than the inner diameter of the third stop portion 713a and the inner diameter of the fourth stop portion 713b, and the width of the second sliding channel 713c is also smaller than the maximum outer diameter of the second positioning portion 1242. When the second locking member 700 moves between the installation position and the fixed position, the second positioning portion 1242 partially penetrates into the second sliding channel 713c. In this way, the situation that the second positioning portion 1242 excessively lifts the locking piece 710 when the second locking member 700 moves between the installation position and the fixed position can be reduced. Moreover, since the second positioning portion 1242 partially penetrates into the second sliding channel 713c instead of completely penetrating into the second sliding channel 713c, when the second positioning portion 1242 slides into the third stop portion 713a or the fourth stop portion 713b, the second positioning portion 1242 can be stably positioned in the third stop portion 713a or the fourth stop portion 713b without external force, so that the locking piece 710 is stably positioned in the installation position and the fixed position.

[0095] It can be understood that when the second positioning portion 1242 penetrates into the third stop portion 713a or the fourth stop portion 713b, the end surface of the body 1241 abuts against the locking piece 710. When the second positioning portion 1242 partially penetrates into the second sliding channel 713c, there is a gap between the end surface of the body 1241 and the locking piece 710 due to the lifting of the second positioning portion 1242. At this time, the locking piece 710 and the body 1241 have a mutual abutting tendency, so that when the second positioning portion 1242 is aligned with the third stop portion 713a or the fourth stop portion 713b, the second positioning portion 1242 will automatically slide into the third stop portion 713a or the fourth stop portion 713b.

[0096] In one embodiment, the second positioning portion 1242 and / or the second limiting structure 713 have elastic deformability. In this way, the second positioning portion 1242 and / or the second limiting structure 713 can be deformed to facilitate the sliding of the second positioning portion 1242 into and out of the third stop portion 713a, and facilitate the sliding of the second positioning portion 1242 into and out of the fourth stop portion 713b.

[0097] Please refer to Figure 10 In one embodiment, the outer wall of the mounting frame 1200 is provided with a second accommodating groove 1250, and the operating portion 720 includes a ball head 721 and a connecting rod 722. When the second locking member 700 is in the fixed position, the ball head 721 is located in the second accommodating groove 1250, and the connecting rod 722 penetrates through the side wall of the mounting frame 1200 and is connected between the ball head 721 and the locking piece 710. By providing the second accommodating groove 1250 for accommodating the ball head 721 in the fixed position, the situation that the ball head 721 in the fixed position is accidentally touched and causes the locking piece 710 to loosen the clamping of the bolt 21 can be avoided.

[0098] Please refer to Figure 10 In one embodiment, the card hole 712 is closer to the operation part 720 than the through hole 711. Thus, the second locking member 700 is aligned with the first through hole 1211a by the through hole 711, and when switched to be aligned with the first through hole 1211a, the operation part 720 is moved inward. Then, the second locking member 700 in the fixed position is closer to the surface of the mounting frame 1200 than the second locking member 700 in the installation position, and the operation part 720 of the second locking member 700 in the fixed position is closer to the surface of the mounting frame 1200 than the second locking member 700 in the installation position, so that the operation part 720 is less likely to be moved to the installation position by mistake. Thus, the operation part 720 can be more stably in the fixed position.

[0099] Please continue to refer to Figure 10 In one embodiment, the bottom wall of the second accommodating groove 1250 is provided with an opening 1251, and the inner diameter of the opening 1251 is smaller than the maximum outer diameter of the ball head 721. Thus, the ball head 721 can be prevented from entering the mounting frame 1200 completely by the blocking effect of the bottom wall of the second accommodating groove 1250 on the ball head 721.

[0100] In one embodiment, the mounting structure 30 includes a plurality of second locking members 700, which are arranged at intervals to be respectively used for clamping and fixing with the plurality of latches 21, so as to improve the stability of the connection between the connection assembly 10 and the display module 20.

[0101] In one embodiment, the mounting frame 1200 is provided with a plurality of first through holes 1211a for the plurality of latches 21 to pass through correspondingly. The plurality of second locking members 700 are respectively aligned with the plurality of first through holes 1211a to be clamped and fixed with the plurality of latches 21. Thus, the mounting structure 30 can be connected and fixed with the display module 20 at multiple points, so as to improve the stability of the connection.

[0102] Please refer to Figure 10 In one embodiment, the mounting frame 1200 is provided with a threaded fastener 1260, the mounting wall 1211 is provided with a first threaded hole 1211b, and the slide rail 1230 is provided with a second threaded hole 1232. The threaded fastener 1260 passes through the first threaded hole 1211b and the second threaded hole 1232 in sequence and is at least threadedly connected with the hole wall of the second threaded hole 1232, so as to lock the slide rail 1230 to the mounting wall 1211. Thus, the slide rail 1230 can be fixed relative to the mounting frame 1200. Moreover, as shown, the position of the locking piece 710 can be limited by the slide rail 1230, so that the locking piece 710 slides in the expected stroke and in the expected direction. Figure 11 to Figure 13
