Additionally, the embodiments described below are merely some embodiments of this application, and not all embodiments.

[0021] A large-size integrated display screen, mounted upright on the ground, is widely used due to its flexibility in movement and arrangement, and the ability for multiple integrated display screens to work in tandem. However, as users' demands for larger display screen sizes continue to increase, these integrated display screens are becoming increasingly bulky, making them inconvenient to package and transport. The larger screen size also makes them more susceptible to damage during transportation. As a result, the cost of using the equipment is constantly rising, while its ease of use is decreasing.

[0022] To address the aforementioned technical issues as much as possible, see [link / reference]. Figures 1 to 5 and Figure 7 In one embodiment of this application, a display screen all-in-one machine is provided, which includes: a base 1, a lifting frame 2, a back support 3, and a display module 4.

[0023] The base 1 supports the main body of the all-in-one display screen, ensuring it stands stably on the ground. The lifting frame 2 is mounted on the base 1 and can be raised or lowered relative to the base 1, thus changing the display height of the all-in-one display screen. The back support 3 is detachably connected to the lifting end of the lifting frame 2; the display module 4 is connected to the back support 3. The connection between the display module 4 and the lifting end of the lifting frame 2 via the back support 3 improves the stability of the connection and facilitates the installation of larger display modules 4 on the lifting frame 2.

[0024] The display module 4 includes at least a first display module 41, a second display module 42, and a third display module 43. The second display module 42 and the third display module 43 are connected to both sides of the first display module 41 via hinges 9. Specifically, the second display module 42 is connected to one side of the first display module 41 via a first set of hinges 9, and the third display module 43 is connected to the other side of the first display module 41 via a second set of hinges 9.

[0025] The two sides of the first display module 41 are either along the horizontal direction of the first display module 41 or along the vertical direction of the first display module 41. Specifically, see... Figure 1 The second display module 42 and the third display module 43 can be respectively disposed in the horizontal direction of the first display module 41 (e.g., Figure 1 As indicated by the middle arrow in the Y direction, the second display module 42 and the third display module 43 can also be respectively disposed on both sides of the first display module 41 in the vertical direction (e.g., as shown by the middle arrow in the Y direction). Figure 1 (As indicated by the X-direction of the middle arrow) on both sides.

[0026] To facilitate the storage and use of display module 4, display module 4 has a folded state and an unfolded state. When display module 4 is in the folded state, the display panels of the second display module 42 and the third display module 43 are folded and stored towards the display panel of the first display module 41. The second display module 42 and the third display module 43 are flipped from the side of the first display module 41 to a position opposite to the first display module 41. In this state, it can be roughly considered that the display panels of the second display module 42 and the third display module 43 are fitted against the display panel of the first display module 41.

[0027] When display module 4 is in the unfolded state, the display panels of the second display module 42 and the third display module 43 are unfolded relative to the display panel of the first display module 41. In this state, the display panels of the second display module 42 and the third display module 43 can be flattened relative to the display panel of the first display module 41, that is, the three display panels are roughly located on the same plane, or the display panels of the second display module 42 and the third display module 43 are set at an angle (obtuse angle) to the display panel of the first display module 41.

[0028] When the display module 4 is in the unfolded state, the edges of the display panels of the second display module 42 and the third display module 43 are respectively aligned with the two side edges of the display panel of the first display module 41, so that the display module 4 forms a large-sized display screen that is almost seamless, which effectively improves the screen viewing experience of the all-in-one display machine.

[0029] To ensure that display module 4 has sufficient structural strength and to facilitate interconnection between different display modules 4. See Figure 1 , Figure 2 and Figure 4 In one embodiment provided in this application, the first display module 41 has a first frame 44, the second display module 42 has a second frame 45, and the third display module 43 has a third frame 46. The frames of different display modules can be connected and assembled to form a complete display module 4.

[0030] The first set of hinges 9 is located on the first side 441 of the first frame 44, and the ends of the first set of hinges 9 are connected to the side of the second frame 45. The second set of hinges 9 is located on the second side 442 of the first frame 44 opposite to the first side 441, and the ends of the second set of hinges 9 are connected to the side of the third frame 46. Specifically, the first side 441 of the first frame 44 has multiple first hollow structures, and the multiple hinges 9 in the first set of hinges 9 are respectively located in the first hollow structures. The side of the second frame 45 is correspondingly provided with multiple second hollow structures, and the ends of the hinges 9 are connected to the second hollow structures. This technical solution is advantageous because the hinges 9 can be hidden in the hollow structures after the display module 4 is unfolded, which not only does not affect the appearance of the display module 4, but also facilitates the display module 4 to be completely flattened.

[0031] The third display module 43 folds from bottom to top. If the third display module 43 is not limited and fixed, it is easy for it to automatically unfold downwards due to gravity. This is not conducive to the folding and storage of the display module 4, and the third display module 43 is easy to automatically unfold and be damaged in case of accident.

[0032] To address this issue as much as possible, one technical solution provided in this application includes a hinge 9 connecting different display modules with a pre-locking force. When the display module 4 is in a folded state, the pre-locking force of the hinge 9 can limit and lock the second display module 42 and the third display module 43, preventing them from accidentally unfolding automatically. When the user needs to unfold the second display module 42 and the third display module 43, by overcoming the pre-locking force of the hinge 9, the second display module 42 and the third display module 43 can be smoothly folded and unfolded.

[0033] After display module 4 is unfolded, the second display module 42 and the third display module 43 also need to be limited to prevent them from folding automatically. See also Figure 1 , Figure 2 and Figure 4 In one embodiment provided in this application, the integrated display screen further includes locking components 5, which are respectively disposed at the hinge connection between the first frame 44 and the second frame 45, and at the hinge connection between the first frame 44 and the third frame 46. Specifically, when the display module 4 is unfolded, the first frame 44 of the first display module 41 will be aligned with the second frame 45 of the second display module 42, and the third frame 46 of the third display module 43 will also be aligned with the first frame 44 of the first display module 41. At this time, it is only necessary to drive the locking components 5 on both sides to switch the locking components 5 to the locked state, and the locking components 5 can limit and lock the first frame 44 and the second frame 45, and the first frame 44 and the third frame 46. The first frame 44, the second frame 45 and the third frame 46 can form a frame body so that the display module 4 is always kept in the unfolded state.

[0034] The most vulnerable area to damage during transport of the all-in-one display screen is the corner area of ​​display module 4. To provide effective protection for the edges of display module 4, please refer to... Figure 1 , Figure 2 and Figure 7 In one embodiment provided in this application, the display screen all-in-one machine also includes edge-binding parts 6, which correspond to the outer edge of the display module 4 in the unfolded state. Multiple edge-binding parts 6 are respectively disposed on the side of the first frame 44, the side of the second frame 45 and the side of the third frame 46.

[0035] Specifically, taking the frame of the first display module 41, the second display module 42, and the third display module 43 as a square structure as an example, the first display module 41 has two edge-sealing pieces 6 on the side of its frame that is not hinged to the other display modules, while the second display module 42 and the third display module 43 have edge-sealing pieces 6 on their other three sides that are not hinged to the first display module 41. When the second display module 42 and the third display module 43 are unfolded relative to the first display module 41, the multiple edge-sealing pieces 6 can form a complete surrounding edge-sealing frame around the display module 4, which can effectively protect the display module 4 from all sides.

[0036] Furthermore, in one embodiment provided in this application, the edge-binding component 6 is detachably connected to the side of the display module 4. Specifically, limiting holes 62 are respectively provided on the side of the first frame 44, the side of the second frame 45, and the side of the third frame 46. The edge-binding component 6 is provided with a mushroom-head connecting part 61, which is detachably connected to the limiting hole 62. The edge-binding component 6 can be installed and removed by simple actions such as sliding and pulling, which is simple to operate and convenient to use.

[0037] In addition to protecting the sides of the frame, the edge banding 6 can also cover the sides of the frame, thereby concealing the locking components 5 and other structures on the sides of the frame, thus improving the overall aesthetics of the display module.

[0038] See Figure 1 , Figure 7 and Figure 8 In one embodiment provided in this application, the first display module 41, the second display module 42, and the third display module 43 each include a base plate 70 and at least one display component 7. The display component 7 is disposed on the base plate 70, and the base plate 70 is connected to the back support 3. Multiple display components 7 can achieve near-seamless splicing, thereby meeting the assembly requirements of large-size display modules.

[0039] In the technical solution provided in this application, the display component 7 is designed as a standard modular component. Users can splice a certain number of display components 7 according to the required size of the display module 4, so that the display module 4 can reach the required size and meet the customization needs of display modules 4 of different sizes.

[0040] In one embodiment provided in this application, the first display module 41, the second display module 42, and the third display module 43 may contain the same or different numbers of display components 7. Display modules of different sizes contain different numbers of display components 7, while display modules of the same size contain the same number of display components 7. For example, the first display module 41 and the second display module 42 contain different numbers of display components 7, while the second display module 42 and the third display module 43 contain the same number of display components 7.

[0041] Furthermore, regarding the size and area of ​​the first display module 41, the second display module 42, and the third display module 43, the total area of ​​the second display module 42 and the third display module 43 can be less than the area of ​​the first display module 41, or the total area of ​​the second display module 42 and the third display module 43 can be equal to the area of ​​the first display module 41. When the second display module 42 and the third display module 43 are folded, the second display module 42 and the third display module 43 can cover the display panel of the first display module 41.

[0042] See Figure 7 and Figure 8 In one embodiment provided in this application, the display component 7 includes a mounting frame 71 and at least one display panel 72, the display panel 72 being disposed on the mounting frame 71. When the display component 7 includes multiple display panels 72, the multiple display panels 72 are assembled and mounted on the mounting frame 71 in a near-seamless splicing manner.

[0043] Display panel 72 includes a circuit board and LED beads disposed on the circuit board.

[0044] Furthermore, the mounting bracket 71 is provided with a locking assembly 5, which includes a first locking part 51 and a second locking part 52. The first locking part 51 can be engaged with the second locking part 52. The first locking part 51 and the second locking part 52 are respectively provided on opposite sides of the mounting bracket 71. Taking the mounting bracket 71 as a square structure as an example, the first locking part 51 and the second locking part 52 are respectively provided on opposite first side 441 and second side 442 of the mounting bracket 71. When the two mounting brackets 71 need to be assembled and connected, the first locking part 51 on the first side 441 of the first mounting bracket 71 can be engaged with the second locking part 52 on the second side 442 of the second mounting bracket 71 to connect the first mounting bracket 71 and the second mounting bracket 71 into one unit.

[0045] In one specific embodiment, the first side 441 and the second side 442 of the mounting bracket 71 are respectively provided with a first groove and a second groove. The first locking part 51 is a locking hook and the second locking part 52 is a connecting post. The locking hook is located in the first groove and the connecting post is located in the second groove. When the locking hook is switched to the locked state, the locking hook can be connected to the connecting post. When the locking hook is switched to the unlocked state, the locking hook can be retracted into the first groove to achieve hidden storage.

[0046] Furthermore, the mounting bracket 71 is also provided with a lock hole 53. By inserting a suitable tool into the lock hole 53, the lock hook can be driven to lock or unlock.

[0047] See Figure 8 The mounting bracket 71 is also provided with a third groove 54. When multiple mounting brackets 71 form a first frame 44, a second frame 45, or a third frame 46, the third groove 54 can be used to install the hinge 9 or the end of the hinge 9.

[0048] As mentioned above, the first frame 44 of the first display module 41, the second frame 45 of the second display module 42, and the third frame 46 of the third display module 43 are connected to each other via locking components 5. These locking components 5 can be the locking components 5 on the mounting bracket 71. Specifically, the display module is composed of multiple display components 7 assembled together, and the mounting brackets 71 of the multiple display components 7, after assembly, form the frame of the display module. That is, the locking components 5 on the outermost side of the mounting bracket 71 can be used to connect with other frames. Additionally, the limiting holes 62 provided on the frame for connecting the edge banding 6 can also be provided on the mounting bracket 71.

[0049] In the technical solution provided in this application, by setting a locking component 5 on the mounting bracket 71, the locking component 5 can not only be used for interconnection between different mounting brackets 71, but also for limiting connection between frames after multiple mounting brackets 71 are combined and connected, satisfying the limiting use after different display modules are unfolded, making one thing multi-purpose and reducing the complexity of the display module 4 structure.

[0050] See Figure 1 and Figure 9 In one embodiment provided in this application, the lifting frame 2 includes a support pipe 21, a lifting sleeve 22, and a lifting device 23. The lifting device 23 is disposed in the support pipe 21, and the lifting sleeve 22 is sleeved outside the support pipe 21. One end of the lifting device 23 is connected to the support pipe 21, and the other end is connected to the lifting sleeve 22. The lifting end is disposed on the pipe wall of the lifting sleeve 22. When the lifting end needs to rise, the lifting device 23 drives the lifting sleeve 22 to rise; when the lifting end needs to fall, the lifting device 23 drives the lifting sleeve 22 to fall.

[0051] The lifting device 23 includes, but is not limited to, lifting cylinders, lifting hydraulic cylinders, lifting linear motors, lead screw devices, etc. The cross-sectional shape of the lifting sleeve 22 includes, but is not limited to, circular, elliptical, square, etc.

[0052] Furthermore, a first connecting plate 25 and a second connecting plate 26 are respectively provided at the upper and lower ends of the lifting sleeve 22 at the lifting end. The first connecting plate 25 and the second connecting plate 26 can be connected to the back support 3 respectively. This technical solution ensures a stable connection between the back support 3 and the lifting frame 2, while also facilitating the installation and disassembly of the lifting frame 2 and the back support 3.

[0053] A connecting pipe 24 is provided on the outer wall of the lifting sleeve 22, with its two ends close to the upper and lower ends of the lifting sleeve 22, respectively. The connecting pipe 24 not only forms a gripping part for easy handling by the user, facilitating the movement of the all-in-one display screen, but also serves as a conduit for cables, allowing for convenient cable concealment. These cables can be power cables or signal cables for different display modules, etc.

[0054] To facilitate the movement and flexibility of the all-in-one display screen, the base 1 is equipped with casters 12, which include, but are not limited to, casters, rubber wheels, etc. To ensure sufficient stability, the base 1 can be a circular chassis with counterweights. Alternatively, the base 1 can include multiple horizontal arms 11, which are distributed in a crisscross pattern to form a stable support structure, with casters 12 located at the ends of the horizontal arms 11. The lengths of the different horizontal arms 11 can be the same or different to meet the needs of all-in-one display screens with different center of gravity distributions.

[0055] Further, see Figure 3 and Figure 7 The display module 4 is also provided with a back plate 8 on the back of the lifting frame 2. The back plate 8 can effectively shield the back of the display module 4, prevent the electronic components on the back from being directly exposed, and also play a certain decorative role.

[0056] As mentioned above, the edging piece 6 around the perimeter of the display module 4 is detachable. Furthermore, the frames of different display modules in the display module 4 are assembled from modular mounting brackets 71, and each mounting bracket 71 is equipped with a locking component 5. This locking component 5 can not only be used to connect different mounting brackets 71 to form the frame of the display module, but also to limit the connection of different display module frames, so that the different display modules remain in the unfolded state.

[0057] Furthermore, the locking component 5 can also be used to connect different all-in-one displays; specifically, see [link to documentation]. Figure 10 and Figure 11When users require a larger display screen, multiple display screens can be assembled and spliced ​​together. After removing the edge trim 6 on the side to be spliced, the locking component 5 on the frame of the display module 4, or the locking component 5 on the edge mounting bracket 71 of the display module 4, can be exposed. Align the sides of the two display modules 4 and then switch the locking component 5 to the locked state through the locking hole 53, so that the multiple display modules 4 can be locked and connected by the locking component 5.

[0058] In summary, in the technical solution of this application, the display module is mounted on a lifting frame, and the display module can be raised and lowered relative to the base. When in use, the display module can be raised relative to the base to improve its viewing experience. After use, the display module can be lowered relative to the base for easy storage and transportation. In addition, the different display modules of the display module can be folded to reduce its overall area, which facilitates the packaging and transportation of the all-in-one display screen and also helps to protect the display panel of the display module.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
