Description

Technical Field

[0001] The present invention relates to the field of electronic display technology, and in particular to a screen power connection component and a 3D screen. Background Art

[0002] 3D screens, as display devices that provide an immersive visual experience, are typically composed of multiple LED screens spliced together to achieve large-area, high-resolution display effects. Existing 3D screens mostly use traditional cable connections. During installation, the cables must be manually plugged into the LED screen connectors, which can easily cause poor contact. Furthermore, the LED screens are electrically connected to each other. If a circuit problem occurs in one LED screen, it will affect other connected LED screens, causing power outages in some areas of the 3D screen.

[0003] Traditional 3D screen installation requires individual wiring for each LED screen. This not only requires specialized technicians, but is also complex and prone to wiring errors. For example, in a large 3D screen project, which may involve wiring dozens or even hundreds of LED screens, a wiring error at any point could cause the entire 3D screen to malfunction. Summary of the Invention

[0004] The purpose of the present invention is to provide a screen power connection component and a 3D screen, which solves the problem of inconvenient electrical connection when splicing existing LED screens, and improves the situation where when the LED screens are electrically connected to each other, a circuit problem in a single LED screen can easily lead to power outages in other connected LED screens and partial areas of the 3D screen.

[0005] To achieve the above-mentioned purpose, the technical solution of the present invention is as follows: a screen power connection component, including a bracket structure and an LED screen, the bracket structure includes several equidistantly distributed columns, and several LED screens spliced together are provided on one side of the bracket structure. Transmission lines are installed inside the columns, and several groups of power contact groups electrically connected to the transmission lines are equidistantly provided on one side of the columns. Each group of power contact groups includes two mutually insulated conductive contacts. Power connection components are installed on both sides of the shell of the LED screen, and the power connection components include conductive contacts matching the power contact groups. When the LED screen is installed to the bracket structure, the power connection components on both sides of the shell contact the power contact groups at corresponding positions of the columns on both sides to form an electrical connection, and the shells of the spliced LED screens are connected through symmetrically arranged connecting components.

[0006] Preferably, the power connection component includes a movable piece and a power terminal. The movable piece is symmetrically slidably connected to the inside of the shell of the LED screen, and the power terminal is installed on the movable piece. The shell of the LED screen is symmetrically provided with strip holes on one side close to the column. The elastic power terminals are aligned one by one with the strip holes. When the movable piece slides along the inside of the shell, a part of the power terminal can slide out of the strip hole and fit with the power contact piece group on the column to form an electrical connection.

[0007] Preferably, the connecting component includes a plug rod and a locking piece, and sockets are symmetrically provided on both sides of the shell of the LED screen. The shells of the LED screens that are spliced together are connected through the plug rod, and the two ends of the plug rod are respectively inserted into the corresponding sockets. Both ends of the plug rod are provided with a first inclined surface, and the first inclined surface is used to push the movable piece to slide through the inclined surface during the process of inserting the plug rod into the shell, so that a part of the power terminal slides out of the strip hole. A locking hole is provided at the top of the plug rod, and a fixing strip is equidistantly fixedly connected to the side of the movable piece away from the column, and a locking piece is slidably connected to the inside of the fixing strip. A second inclined surface is provided at the bottom of the locking piece. When the plug rod is inserted into the shell, the second inclined surface contacts the top of the plug rod, pushing the locking piece up. When the plug rod is inserted into the specified position, the locking hole is aligned with the locking piece, and the locking piece descends under the action of its own gravity and is inserted into the locking hole to position the plug rod.

[0008] Preferably, the movable sheet is internally slidably connected to a plurality of slide rods, one end of the slide rod is fixedly connected to the inner wall of the shell of the LED screen, and a spring is sleeved on the outer side of the slide rod, and the movable sheet is elastically connected to the inner wall of the shell through the spring.

[0009] Preferably, fixing plates are equidistantly provided on one side of the column, and the fixing plates are arranged at the joint of the upper and lower distributed LED screens. Waist-shaped holes are provided at the four corners of the fixing plates, and threaded tubes are fixedly connected to the four corners of the LED screen shell corresponding to the waist-shaped holes. Bolts are slidably inserted into the waist-shaped holes, and one end of the bolt passes through the corresponding LED screen shell, movable plate, plug-in rod, and locking plate in sequence, and is threadedly connected to the threaded tube.

[0010] Preferably, the bracket structure also includes a crossbeam, which is arranged at the bottom end of the column, and the bottom end of the column is fixedly connected to the crossbeam, and the top of the crossbeam is in contact with the adjacent LED screen. The LED screen is supported by the crossbeam, making the LED screen more stable and regular during installation.

[0011] Preferably, strip-shaped grooves are provided on both sides of the locking piece, and the sliding range of the locking piece is limited by the strip-shaped grooves to prevent the locking piece from being separated from the fixing strip during the sliding process.

[0012] Preferably, an adjustment bar is symmetrically slidably connected inside the shell of the LED screen, and one side of the locking piece is fixedly connected to the corresponding adjustment bar. By dragging the adjustment bar, the two locking pieces on the same side can be driven to slide at the same time, so that the locking piece can be pulled out of the locking hole.

[0013] Preferably, a gasket is provided between the bolt and the fixing plate, and the contact area between the end of the bolt and the connecting component is enlarged by the gasket, so that the pressure distribution is more uniform, thereby enhancing the fastening effect.

[0014] The present invention also provides a 3D screen, which is assembled using the above-mentioned screen power connection component, and the 3D screen is composed of several LED screens spliced on a bracket structure.

[0015] Compared with the prior art, the advantages of the present invention are as follows:

[0016] The present invention realizes parallel power supply for multiple screens through the transmission line inside the column. The failure of a single screen will not affect the operation of other screens, thereby improving the stability of the system. The power connection components are integrated with the LED screen shell. No additional wiring operation is required during installation. Only the LED screen needs to be placed on the bracket structure, and the power connection components can automatically contact the power connection contact group to achieve quick power connection, simplify the installation process, and reduce installation time and labor costs.

[0017] The present invention triggers the sliding of the movable piece and the self-locking of the locking piece simultaneously through the insertion action of the plug rod, ensuring that the power terminals are automatically exposed after splicing and the non-power terminals remain hidden, avoiding the risk of accidental electric shock. The movable piece, the plug rod, the locking piece and the housing of the LED screen are synchronously fixed by bolts to enhance the stability of the overall structure.

[0025] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] See also Figures 1 to 6 , this embodiment provides a screen power connection component, including a support structure 100 and an LED screen 200, the support structure 100 includes a plurality of equally distributed columns 1, a plurality of mutually spliced LED screens 200 are provided on one side of the support structure 100, a transmission line 2 is installed inside the column 1, and a plurality of groups of power contact pieces 3 electrically connected to the transmission line 2 are equidistantly provided on one side of the column 1, each group of power contact pieces 3 includes two mutually insulated conductive contact pieces 31, power connection components 300 are installed on both sides of the shell 4 of the LED screen 200, and the power connection components 300 include conductive contacts 5 matching the power contact pieces 3. When the LED screen 200 is installed on the support structure 100, the power connection components 300 on both sides of its shell 4 contact the power contact pieces 3 at corresponding positions of the columns 1 on both sides to form an electrical connection, and the shells 4 of the mutually spliced LED screens 200 are connected by symmetrically arranged connecting components 400;

[0027] By equidistantly arranging multiple sets of conductive contacts on the side wall of the column 1, modular power connection of the LED screen 200 is achieved, replacing the traditional cable connection method. The transmission line 2 inside the column 1 realizes parallel power supply for multiple screens. When the display module of one of the LED screens 200 fails, the other LED screens 200 can still remain powered through the transmission line 2, so that the failure of a single screen will not affect the operation of other screens, thereby improving system stability.

[0028] The power connection component 300 includes a movable piece 6 and a power terminal 7. The movable piece 6 is symmetrically slidably connected to the interior of the housing 4 of the LED screen 200. The power terminal 7 is installed on the movable piece 6. The housing 4 of the LED screen 200 is symmetrically provided with a strip hole 8 on one side close to the column 1. The power terminal 7 is aligned with the strip hole 8. When the movable piece 6 slides along the interior of the housing 4, a portion of the power terminal 7 can slide out of the strip hole 8 and fit into the power contact piece group 3 on the column 1 to form an electrical connection.

[0029] The elastic electrical terminal 7 is controlled to extend and retract by the sliding movable piece 6 to achieve contact with the electrical contact piece group 3 of the column 1 to form an electrical connection.

[0030] The connecting assembly 400 includes a plug rod 9 and a locking piece 10. The housing 4 of the LED screen 200 is symmetrically provided with sockets 11 on both sides. The housings 4 of the LED screens 200 that are spliced together are connected through the plug rod 9. The two ends of the plug rod 9 are respectively inserted into the corresponding sockets 11. Both ends of the plug rod 9 are provided with a first inclined surface 12. The first inclined surface 12 is used to push the movable piece 6 to slide through the inclined surface during the process of inserting the plug rod 9 into the housing 4, so that a part of the power terminal 7 slides out of the strip hole 8, and the top of the plug rod 9 A locking hole 13 is opened, and a fixing strip 14 is fixedly connected to the side of the movable piece 6 away from the column 1 at an equal distance. A locking piece 10 is slidably connected inside the fixing strip 14. A second inclined surface 15 is provided at the bottom of the locking piece 10. When the plug rod 9 is inserted into the housing 4, the second inclined surface 15 contacts the top of the plug rod 9, pushing the locking piece 10 up. When the plug rod 9 is inserted into the specified position, the locking hole 13 is aligned with the locking piece 10. The locking piece 10 descends under the action of its own gravity and is inserted into the locking hole 13 to position the plug rod 9.

[0031] Through the insertion action of the plug rod 9, the movable piece 6 is linked to slide, so that the power terminal 7 of the LED screen 200 that needs to be connected to electricity slides out of the strip hole 8 to form an electrical connection. The power terminal 7 of the LED screen 200 that does not need to be connected to electricity remains hidden when the movable piece 6 is not pushed, avoiding contact with the power contact group 3 of the column 1, thereby improving installation safety.

[0032] The movable piece 6 is slidably connected to a plurality of slide rods 16. One end of the slide rod 16 is fixedly connected to the inner wall of the housing 4 of the LED screen 200. The outer side of the slide rod 16 is provided with a spring 17. The movable piece 6 is elastically connected to the inner wall of the housing 4 through the spring 17.

[0033] When the plug-in rod 9 is inserted into the socket 11, the first inclined surface 12 of the plug-in rod 9 pushes the movable piece 6 to slide along the slide rod 16, and the spring 17 is compressed. When the LED screen 200 needs to be disassembled, the locking piece 10 is pushed out of the locking hole 13 by external force, and the movable piece 6 automatically resets under the elastic restoring force of the spring 17, driving the power terminal 7 to retract into the strip hole 8, avoiding the risk of live operation.

[0034] One side of the column 1 is equidistantly provided with fixing plates 18, which are arranged at the joint of the upper and lower distributed LED screens 200. Waist-shaped holes 19 are opened at the four corners of the fixing plate 18. The four corners of the housing 4 of the LED screen 200 corresponding to the waist-shaped holes 19 are fixedly connected with threaded barrels 20. Bolts 21 are slidably inserted into the waist-shaped holes 19. One end of the bolt 21 passes through the housing 4 of the corresponding LED screen 200, the movable plate 6, the plug rod 9, and the locking plate 10 in sequence, and is threadedly connected to the threaded barrel 20.

[0035] Through the cooperation of the fixing piece 18 and the bolt 21, the splicing accuracy of the upper and lower distributed LED screens 200 is ensured, and the splicing gap is avoided to be too large or misaligned. Multiple LED screens 200 are fixedly installed on the bracket structure 100. The bolt 21 synchronously fixes the movable piece 6, the plug rod 9, the locking piece 10 and the shell of the LED screen 200 to enhance the stability of the overall structure. At the same time, once the bolt 21 is assembled, it can be ensured that the locking piece 10 is always inserted in the locking hole 13 to ensure that the power terminal 7 and the power contact piece group 3 on the column 1 remain in contact.

[0036] The support structure 100 also includes a crossbeam 22, which is arranged at the bottom end of the column 1, and the bottom end of the column 1 is fixedly connected to the crossbeam 22. The top of the crossbeam 22 is in contact with the adjacent LED screen 200. The LED screen 200 is supported by the crossbeam 22, making the LED screen 200 more stable and regular during installation.

[0037] Strip grooves 23 are formed on both sides of the locking piece 10 to limit the sliding range of the locking piece 10 so as to prevent the locking piece 10 from being separated from the fixing strip 14 during the sliding process.

[0038] The shell 4 of the LED screen 200 is symmetrically slidably connected with an adjustment bar 24, and one side of the locking piece 10 is fixedly connected to the corresponding adjustment bar 24. By dragging the adjustment bar 24, the two locking pieces 10 on the same side can be driven to slide at the same time, so that the locking piece 10 can be pulled out of the locking hole 13.

[0039] A gasket 25 is provided between the bolt 21 and the fixing plate 18. The gasket 25 is an annular structure. The inner ring diameter matches the screw diameter of the bolt 21, and the outer ring diameter is larger than the width of the waist-shaped hole 19. The gasket 25 expands the contact area between the end of the bolt 21 and the connecting component, making the pressure distribution more uniform, thereby enhancing the fastening effect.

[0040] See also Figures 1 to 6 The present invention also provides a 3D screen that is assembled using any of the above-mentioned screen power connection components, and the 3D screen is composed of several LED screens 200 spliced on a support structure 100.
