[0002] In the prior art, a patent document with the publication number CN116469316A discloses a spliced display screen, which includes a first box body and a second box body connected to each other. Each box body includes a display module provided on one side of the box body. Each of the box bodies includes a back plate and side plates fixedly connected to the side edges of the back plate. The display module is installed on the side of the box body opposite to the back plate. The above display screen can achieve electrical connection between adjacent two display modules, with simple operation, neat and beautiful lines, and reliable connection. However, the above display screen has the following technical problems when in use: 1. Lack of protection function for splicing points. For the display modules near the splicing points, the prior art lacks comprehensive protection measures. The existing intelligent display screens have insufficient shock absorption and protection for the splicing points, and in the prior art, there is a lack of a structure to effectively prevent the splicing points from loosening when the splicing modules are connected; 2. Poor connection stability of the splicing modules. The connection method between the splicing modules and the back frame of the traditional intelligent display screen is complex, lacking an efficient, stable and simple quick connection structure, which affects the overall structural stability of the intelligent display screen. As a result, the existing display screen may have displacement of the splicing modules due to factors such as slight vibration during use, which in turn affects the splicing quality and use safety of the display screen.

[0003] 3. Poor control of splicing gaps: It is difficult for the prior art to effectively control the gaps between the splicing modules; Based on this, the present invention provides an intelligent display screen with a splicing point protection function to solve the technical problems mentioned in the above background art. Summary of the Invention

[0009] As a preferred technical solution of the present invention, the connecting mechanism includes a plurality of T-shaped guide rods installed on the back of the display module. Each T-shaped guide rod is slidably connected to the splicing frame. A spring is sleeved on each T-shaped guide rod at positions corresponding to both sides of the splicing frame. An air pump is installed on the splicing frame. Two symmetrically arranged floating bags are installed between the splicing frame and the display module. The port of the air pump is communicated with the inner cavities of the two floating bags through a first pipeline. The port of the air pump is communicated with the inner cavity of the bag-shaped protective belt through a second pipeline. Pressure probes are arranged at the joints of the air pump with the first pipeline and the second pipeline.

[0010] As a preferred technical solution of the present invention, a data socket and two symmetrically arranged positioning magnetic grooves are provided on one side surface of the splicing frame. A data terminal and two symmetrically arranged magnetic insertion posts are installed on the other side surface of the splicing frame. The data terminal is adaptively connected to the data socket. The two magnetic insertion posts are respectively adaptively connected to the two positioning magnetic grooves.

[0011] As a preferred technical solution of the present invention, both the main protective wing and the side protective wing include an inner skeleton. The inner skeleton is made of metal material, and a silica gel protective layer is wrapped on the inner skeleton. The bag-shaped protective belt is made of silica gel material and expands along the outer edge of the display module after inflation to form an annular protective layer.

[0012] As a preferred technical solution of the present invention, a plurality of ventilation boxes are regularly installed on the back surface of the back frame. A ventilator is installed on each ventilation box. A plurality of regularly distributed air supply holes communicating with the inner cavity of the ventilation box are opened on the back frame at positions corresponding to each ventilation box. The ventilation boxes are arranged at the splicing positions of two adjacent splicing modules.

[0013] As a preferred technical solution of the present invention, two beam plates are installed on the back surface of the back frame. A plurality of locking screw rods are threadedly installed on one beam plate. Locking screw tubes are installed on the other beam plate at positions corresponding to each locking screw rod. The locking screw tubes are adaptively connected to the threaded rods.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. By setting the main protective wing and the side protective wing and realizing their synchronous rotation through the multi-axis synchronous transmission mechanism, the display module is wrapped and protected when the display screen is in the non-installed state, effectively solving the problem of insufficient protection of the display module near the splicing point of the existing intelligent display screen. At the same time, a bag-shaped protective belt that can be inflated and expanded is arranged at the outer edge of the display module. After splicing is completed, the air pump inflates it to form a protective layer, further strengthening the protection. Compared with the prior art, the risk of the side edge of the display module being damaged by collision is greatly reduced, and the service life of the display screen is extended. This is the key innovation point of the present invention to solve the protection problem of the splicing point, realizing all-round protection of the display module at the splicing point from the hardware structure. Compared with the traditional protection method, the protection effect is more remarkable.

[0015] 2. During the connection process of the splicing modules of the present invention, by rotating the synchronization shaft, the threaded rod is threadedly connected to the connecting screw tube, which can effectively reduce the connection gap between the two splicing modules by using the threading force, avoiding problems such as excessive splicing gaps or image display misalignment. Moreover, when installing the splicing modules, the position of each display module can be adjusted by controlling the inflation amount in the floating bladder, further reducing the misalignment rate and gap rate between multiple splicing modules. Compared with the prior art where it is difficult to effectively control the gap between splicing modules, the present invention starts from two aspects: the connection structure and the position adjustment of the display modules, achieving precise control of the splicing gap and improving the imaging effect of the intelligent display screen. This is a creative breakthrough of the present invention in the control of splicing gaps.

[0016] 3. The present invention utilizes a bidirectional locking module. By rotating the synchronization shaft, its positive and negative threaded sections drive the clamp to cooperate with the positioning clamp opening of the back frame, and the positioning magnet enhances the magnetic connection, simplifying the installation process and improving the installation efficiency. Compared with the traditional method, there is no need for cumbersome operations, and only by rotating the synchronization shaft, the preliminary fixation can be completed. The connection is more firm, effectively preventing the splicing modules from loosening, enhancing the overall structural stability of the display screen, and ensuring the splicing quality and use safety.

[0017] 4. The invention realizes rapid data transmission and interaction and precise positioning during splicing through the data socket, data terminal, positioning magnetic groove, and magnetic plug post on the side of the splicing frame. Compared with the prior art, it reduces the splicing error, improves the splicing efficiency and quality, avoids data transmission interruption or abnormal display, ensures the normal operation of the intelligent display screen, and enhances the user experience. The present invention sets a ventilation box and a ventilator at the splicing place on the back of the back frame. The ventilator inhales the outside air and blows it towards the splicing modules and display modules through the air supply holes, focusing on dissipating heat from the electronic components at the splicing place. Compared with the traditional heat dissipation method, it has stronger pertinence, can effectively reduce the temperature of the components, ensure the stable operation of the electronic components, extend the service life of the display screen, and reduce the frequency of faults.

Detailed implementation manners

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] As Figures 1 to 9 shown, the present invention provides an intelligent display screen with a splicing point protection function, including a back frame 1, and a group of spliceable splicing modules 2 are arranged on the back frame 1; The splicing module 2 includes a splicing frame 3, and two synchronizing shafts 4 are rotatably installed on the splicing frame 3, and the two synchronizing shafts 4 are interconnected by a synchronous toothed belt; Gears meshing with the synchronous toothed belt are fixedly arranged on the synchronizing shaft 4; A two-way locking module connected to the back frame 1 is arranged on one synchronizing shaft 4; The two-way locking module includes a positive thread section and a reverse thread section opened on one synchronizing shaft 4. The pitches of the positive thread section and the reverse thread section are the same. A clamp 12 is drivingly installed on both the positive thread section and the reverse thread section. The two clamps 12 are both slidably connected to the splicing frame 3. A positioning clamp 13 cooperating with the two clamps 12 is fixedly arranged on the back frame 1, and a plurality of positioning magnets 14 magnetically attracted to the back frame 1 are embedded in the splicing frame 3; When installing the splicing module 2 of the intelligent display screen, rotate the synchronous shaft 4. The positive thread section and the reverse thread section on the synchronous shaft 4 drive two clamps 12 to slide along the splicing frame 3. The clamps 12 are precisely matched with the positioning clamp openings 13 of the back frame 1, realizing the preliminary fixation of the splicing frame 3 and the back frame 1. At the same time, the positioning magnetic blocks 14 on the splicing frame 3 are magnetically attracted to the back frame 1, enhancing the connection stability. This solution solves the problems of unstable connection and cumbersome operation during the installation of the traditional intelligent display screen splicing module 2. Compared with the prior art, its prominent advantage lies in simplifying the installation process. Only by rotating the synchronous shaft 4 can the connection be completed, improving the installation efficiency. The cooperation of the positioning magnetic blocks 14 and the clamps 12 makes the connection more firm, effectively preventing the splicing module 2 from loosening, ensuring the stability of the overall structure of the intelligent display screen, and further improving the splicing quality and use safety of the display screen; Two screw sleeves 5 and two connecting screw pipes 6 are installed on the splicing frame 3. A threaded rod 7 is installed in each of the two screw sleeves 5. The two threaded rods 7 are respectively driven by two synchronous shafts 4, and the two threaded rods 7 are respectively in threaded cooperation with the two connecting screw pipes 6; Drive grooves with open ends are provided inside the two threaded rods 7. A driving section 15 is provided on each of the two synchronous shafts 4. The two driving sections 15 are respectively slidably connected to the two drive grooves. The cross-sections of the driving section 15 and the drive groove are both regular hexagons; After the two splicing modules 2 are aligned, the user drives the synchronous shaft 4 to rotate. When the synchronous shaft 4 rotates, its driving section 15 slides in the regular hexagon drive groove of the threaded rod 7, stably transmitting power to the threaded rod 7, causing the threaded rod 7 to rotate accordingly. The threaded rod 7 in one splicing module 2 is threadedly connected to the connecting screw pipe 6 in the other splicing module 2 under the driving action of the synchronous shaft 4. When the synchronous shaft 4 is tightened, the firm connection and position limitation of the two splicing modules 2 are completed; Through the connection and locking setting of the two splicing modules 2, the connection gap at the two splicing modules 2 can be effectively reduced by using the thread force and the problem of too large splicing gap or image display misalignment can be avoided, thereby improving the imaging effect of the intelligent display screen; Moreover, through the connection setting of the two splicing modules 2, the phenomenon of loosening between the two splicing modules 2 can be effectively avoided; Two symmetrically arranged main protective wings 8 and two symmetrically arranged side protective wings 9 are respectively hinged on the splicing frame 3; Both the main protective wing 8 and the side protective wing 9 include an inner skeleton. The inner skeleton is made of metal, and a silica gel protective layer is wrapped on the inner skeleton. The airbag protection belt 11 is made of silica gel and expands along the outer edge of the screen display module 10 after inflation to form an annular protective layer; A multi-axis synchronous transmission mechanism is provided on the splicing frame 3. Both the main protective wing 8 and the side protective wing 9 are driven by the multi-axis synchronous transmission mechanism and rotate synchronously; The multi-axis synchronous transmission mechanism includes a main shaft 16, a transmission shaft 17, an upper gear shaft 18 and a lower gear shaft 19 which are rotatably connected to the back frame 1. A transmission handle is installed on the main shaft 16 and a synchronous shaft 4. A first bevel gear is installed on the main shaft 16 and the transmission shaft 17. The two first bevel gears are meshed with each other. A second bevel gear is installed on the transmission shaft 17. The bottom end of the upper gear shaft 18 and the top end of the lower gear shaft 19 are fixedly installed with a third bevel gear meshed with the second bevel gear. A fourth bevel gear is fixedly installed at both ends of the transmission shaft 17. A fifth bevel gear is installed on each of the two side wings 9. The two fifth bevel gears are respectively connected to the two fourth bevel gears in transmission. A fifth bevel gear is fixedly installed on the top end of the upper gear shaft 18 and the bottom end of the lower gear shaft 19. A sixth bevel gear is fixedly installed on each of the two main wings 8. The two fifth bevel gears are respectively connected to the two sixth bevel gears in transmission. When the display screen is not installed, the main protection wing 8 and the side protection wing 9 wrap around the outer periphery of the display module 10 to protect the display module 10; Before the display screen is installed, the transmission handle on the main shaft 16 is rotated, and the main shaft 16 drives the transmission shaft 17 to rotate. Through the meshing transmission of bevel gears at various levels, the bevel gears on the upper gear shaft 18, the lower gear shaft 19, the side wings 9, and the main wings 8 work together to achieve the synchronous rotation of the main wings 8 and the side wings 9, and finally make the side wings 9 and the main wings 8 lose their wrapping and protective effect on the display module 10, and the side wings 9 and the main wings 8 rotate to the rear side of the display module 10 and are blocked by the display module 10; The provision of the main wing 8 and the side wing 9 solves the problem that the side edge protection of the display module 10 of the existing smart display screen is insufficient and susceptible to collision damage. Compared with the traditional protection structure, the multi-axis synchronous transmission mechanism can ensure that the main wing 8 and the side wing 9 move in a timely and consistent manner, and the protection effect is significantly improved, which effectively reduces the risk of damage to the display module 10 caused by collision, prolongs the service life of the smart display screen, and improves its safety in use; In actual use, by setting the positions and specifications of the multiple bevel gears in the multi-axis synchronous transmission mechanism, and the speed settings of the transmission shaft 17, the upper gear shaft 18 and the lower gear shaft 19, it should be ensured that when the main shaft 16 rotates, the main wing 8 and the side wing 9 can rotate inwards or outwards at the same speed synchronously; The splicing frame 3 is connected to a display module 10 through a connecting mechanism, and the main protective wing 8 and the side protective wing 9 are used to protect the side edges of the display module 10; The beneficial effect of adopting the above solution is that the connecting mechanism controls the distance between the display module 10 and the splicing frame 3 and provides shock-absorbing protection for the display module 10 . The outer edge of the display module 10 is provided with an inflatable bag protection belt 11 .

[0022] The connecting mechanism includes a plurality of T-shaped guide rods 20 installed on the back of the display module 10. Each T-shaped guide rod 20 is slidably connected to the splicing frame 3. A spring 21 is sleeved on each T-shaped guide rod 20 at positions corresponding to both sides of the splicing frame 3. An air pump 22 is installed on the splicing frame 3. Two symmetrically arranged floating bags 23 are installed between the splicing frame 3 and the display module 10. The port of the air pump 22 is communicated with the inner cavities of the two floating bags 23 through a first pipeline. The port of the air pump 22 is communicated with the inner cavity of the bag-shaped protective belt 11 through a second pipeline. A pressure probe is arranged at the connection of the air pump 22 with the first pipeline and the second pipeline.

[0023] When each splicing module 2 is installed, the position of each display module 10 can be adjusted by controlling the inflation amount in the floating bag 23, thereby reducing the misalignment rate and gap rate between the plurality of splicing modules 2. When the intelligent display screen is vibrated, the display module 10 slides on the splicing frame 3 through the T-shaped guide rod 20. The spring 21 on the T-shaped guide rod 20 plays a preliminary shock-absorbing role, and the floating bag 23 expands to provide buffering for the distance between the display module 10 and the splicing frame 3. After the stable connection of two splicing modules 2 is completed, the air pump 22 also inflates the bag-shaped protective belt 11 through the second pipeline. The bag-shaped protective belt 11 expands to form a protective layer on the outer edge of the display module 10, which solves the problems in the prior art that the display module 10 is easily affected by vibration during use and the protection measures are imperfect. Compared with the traditional connection and protection methods, this connecting mechanism realizes the all-round shock-absorbing protection of the display module 10. It can not only effectively control the distance between the display module 10 and the splicing frame 3, but also provide multiple buffering protections during vibration, greatly reducing the possibility of damage to the display module 10 due to vibration and improving the stability and reliability of the intelligent display screen. The air pump 22 controls the inflation amount of the floating bag 23 through the pressure probe. The sliding direction of the T-shaped guide rod 20 and the splicing frame 3 is perpendicular to the plane of the display module 10. One side of the splicing frame 3 is provided with a data socket 24 and two symmetrically arranged positioning magnetic grooves 25. The other side of the splicing frame 3 is installed with a data terminal 26 and two symmetrically arranged magnetic plug posts 27. The data terminal 26 is adaptively connected to the data socket 24, and the two magnetic plug posts 27 are respectively adaptively connected to the two positioning magnetic grooves 25.

[0024] When splicing multiple splicing modules 2, the data terminals 26 on the side of one splicing frame 3 are accurately docked with the data sockets 24 on the side of the adjacent splicing frame 3 to achieve fast data transmission and interaction. At the same time, the magnetic insertion posts 27 are inserted into the positioning magnetic grooves 25 to accurately position the relative positions of the splicing frames 3 by using magnetism. This solves the problems of difficult data connection and inaccurate positioning in traditional splicing methods. Compared with the prior art, this structural design makes the data connection and positioning between the splicing modules 2 more convenient and efficient, reduces the error in the splicing process, improves the splicing efficiency and quality, ensures that the intelligent display screen can display images and transmit data normally after splicing, and avoids the situation of data transmission interruption or abnormal display; A plurality of ventilation boxes 28 are regularly installed on the back surface of the back frame 1. A ventilator 29 is installed on each ventilation box 28. A plurality of regularly distributed air supply holes 30 that are communicated with the inner cavity of the ventilation box 28 are opened on the back frame 1 at positions corresponding to each ventilation box 28. The ventilation box 28 is arranged at the splicing position of two adjacent splicing modules 2.

[0025] When the ventilator 29 works, it sucks the outside air into the ventilation box 28, and the air blows towards the splicing module 2 and the screen display module 10 through the air supply holes 30 on the back frame 1. Since the ventilation box 28 is arranged at the splicing position of two adjacent splicing modules 2, it can focus on dissipating heat from the electronic components at the splicing position, effectively reducing the component temperature. This solves the problem of poor heat dissipation at the splicing position of the existing intelligent display screen and the easy performance degradation of components caused by heat accumulation. Compared with the traditional heat dissipation method, this heat dissipation structure has stronger pertinence, can quickly and effectively take away the heat generated at the splicing position, ensures that the electronic components work in a suitable temperature environment, improves the stability and reliability of the intelligent display screen, extends its service life, and reduces the frequency of failures caused by overheating; Two beam plates 31 are installed on the back surface of the back frame 1. A plurality of locking screws 32 are threadedly installed on one beam plate 31. Locking screw tubes 33 are installed on the other beam plate 31 at positions corresponding to each locking screw 32. The locking screw tubes 33 are adaptively connected to the threaded rods 7.

[0026] After the installation and adjustment of the splicing module 2 are completed, rotate the locking screw 32 to make it closely cooperate with the locking screw tube 33 to firmly fix the threaded rod 7. This prevents the threaded rod 7 from rotating due to factors such as vibration during use, ensures the stable connection between the splicing modules 2, and solves the problem that the splicing module 2 of the existing intelligent display screen is prone to looseness and affects the display effect during use. Compared with the traditional fixing method, this structure can better lock the position of the splicing module 2 through the cooperation of the locking screw 32 and the locking screw tube 33, enhances the stability of the overall structure of the intelligent display screen, ensures that the display screen maintains a good display state during long-term use, and reduces the frequency of readjustment and maintenance required due to the looseness of the splicing module 2; The working principle and usage process of the present invention: The intelligent display screen with the function of protecting splicing points involved in the present invention has a working process covering multiple key links. During installation, first connect the splicing module 2 with the back frame 1, rotate the synchronous shaft 4, and use the positive thread section and the reverse thread section on the synchronous shaft 4 to drive the clamp 12 to cooperate with the positioning clamp opening 13 of the back frame 1. At the same time, the positioning magnet 14 enhances the connection stability to complete the preliminary fixation. Then, connect the splicing modules 2. Rotate the synchronous shaft 4, drive the threaded rod 7 to rotate through the transmission section 15, and threadedly connect with the connecting screw tube 6 of another splicing module 2 to achieve fastening and position limitation. Before installation, if it is necessary to protect the display module 10, rotate the transmission handle on the main shaft 16. Through the multi-axis synchronous transmission mechanism, the bevel gears at all levels mesh and drive to drive the main protective wing 8 and the side protective wing 9 to rotate synchronously to wrap and protect the display module 10. When installing the display module 10, rotate the transmission handle on the main shaft 16 again to rotate the main protective wing 8 and the side protective wing 9 to the rear side of the display module 10. During the installation process of the splicing module 2, use the connection mechanism to adjust the position of the display module 10. By controlling the inflation amount of the floating bladder 23, the splicing misalignment rate and the gap rate are reduced. During vibration, the T-shaped guide rod 20 and the spring 21 initially dampen the vibration, and the floating bladder 23 further buffers. After splicing is completed, the air pump 22 inflates the bladder protection belt 11 to form a protective layer and reduce the gap rate at the connection of two adjacent splicing modules 2. By reducing the gap rate, the dust ingress rate at the connection gap of two adjacent splicing modules 2 is effectively reduced. When splicing multiple splicing modules 2, the data terminal 26 is docked with the data socket 24 to achieve data transmission, and the magnetic plug post 27 cooperates with the positioning magnetic groove 25 for precise positioning. During the operation of the display screen, the ventilator 29 on the ventilation box 28 on the back of the back frame 1 inhales the outside air and dissipates heat from the electronic components at the splicing part through the air supply holes 30. After the installation and adjustment are completed, rotate the locking screw rod 32 to cooperate with the locking screw tube 33 to fix the threaded rod 7 to prevent the splicing module 2 from loosening and ensure the stable operation of the display screen to achieve a good display effect.
