Description

Technical Field

[0001] This utility model relates to the field of LED screen structure technology, and in particular to an LED screen installation and disassembly structure based on air suction. Background Technology

[0002] LED screens are made up of several LED light panels. Due to their high brightness, wide viewing angle, and long lifespan, they are often used as outdoor advertising screens or outdoor stage displays.

[0003] In general, LED light panels are fixed to the bracket with screws. There are also quick-release LED modules. Existing technical solutions generally use neodymium magnets as fasteners to fix the LED light panels to the bracket by magnetic attraction.

[0004] While magnetic solutions allow for quick assembly and disassembly of LED light boards, the boards generate heat during operation. Prolonged exposure to high temperatures can demagnetize the magnets, affecting the board's stability.

[0005] Therefore, it is necessary to provide an LED screen installation and disassembly structure based on air suction to solve the above-mentioned technical problems. Summary of the Invention

[0006] To solve the above-mentioned technical problems, this utility model provides an LED screen installation and disassembly structure based on air suction.

[0007] This utility model provides an LED screen installation and disassembly structure based on air suction, characterized in that it includes: a mounting plate, multiple LED light panels, a single-module controller, an adsorption device, and a telescopic rotation device; the mounting plate is equipped with multiple horizontal plates and multiple vertical plates to form multiple mounting slots; each mounting slot is provided with a single-module controller, at least one adsorption device, and at least one pair of telescopic rotation devices, the single-module controller in each mounting slot controls the corresponding adsorption device, the telescopic rotation device, and communicates with the corresponding LED light panel, the adsorption device in each mounting slot adsorbs one corresponding LED light panel, and the pair of telescopic rotation devices in each mounting slot are detachably connected to both sides of the corresponding LED light panel; each telescopic rotation device is configured to drive the LED light panel into or out of the mounting slot when telescopic, and to lock the connection to the LED light panel when rotating.

[0008] In a further embodiment of this utility model, the telescopic rotation device includes: a motor, mounted on the mounting plate; a cylinder, mounted on the power output shaft of the motor; and a telescopic rod, partially mounted inside the cylinder and detachably connected to the LED light panel.

[0009] In a further embodiment of this utility model, a lock head is provided on the telescopic rod, and a rotating locking groove is provided on the LED light panel. The motor drives the lock head to rotate and engage in the rotating locking groove, so that the telescopic rotation device is locked and connected to the LED light panel.

[0010] In a further embodiment of this utility model, the telescopic rod includes a fixed rod and a moving rod. The fixed rod is disposed on the power output shaft of the motor, and the moving rod is movably connected to the fixed rod. The fixed rod is provided with an anti-deflection protrusion that extends along the axial direction of the telescopic rod. The moving rod is provided with an anti-deflection groove, and the fixed rod extends along the axial direction of the telescopic rod. The anti-deflection protrusion is engaged in the anti-deflection groove.

[0011] In a further embodiment of this utility model, the telescopic rotation device further includes a first pump body and a pump controller. The pump controller is disposed on the first pump body and electrically connected to the first pump body. The first pump body is connected to the cylinder to supply air to the cylinder.

[0012] From the perspective of installation and disassembly efficiency, when installing the LED light panel, the motor starts and drives the fixed rod in the telescopic rod to rotate, adjusting the telescopic rod to the appropriate angle. Then, the cylinder drives the telescopic rod to extend, accurately and quickly inserting it into the corresponding position of the LED light panel. After rotation and locking, the cylinder drives the telescopic rod to retract, completing the installation connection. The entire process is fast and greatly shortens the installation time. During disassembly, the cylinder first drives the telescopic rod to extend, pulling the LED light panel a certain distance from the mounting slot. Pressing the LED light panel compresses the spring on the telescopic rod. Then, the motor drives the fixed rod in the telescopic rod to rotate again, disengaging the telescopic rod from the LED light panel and achieving rapid disassembly. Compared to traditional methods, this operation method greatly simplifies the installation and disassembly process and significantly improves work efficiency, especially in the installation and maintenance of large-scale LED screens, where its advantages are even more pronounced. Secondly, in terms of connection stability, the cooperation between the cylinder and the telescopic rod provides a reliable mechanical connection. The cylinder can precisely control the extension and retraction length and force of the telescopic rod, ensuring a stable and secure connection between the telescopic rod and the LED light panel. During the use of the LED screen, even if it is affected by external vibration or impact, the telescopic rod can maintain a tight connection with the LED light panel under the action of the cylinder, and there will be no loosening or falling off, which effectively ensures the normal operation of the LED screen.

[0013] In a further embodiment of this utility model, the adsorption device includes a base plate, a vacuum nozzle, and a second pump body. The base plate and the second pump body are both disposed on the mounting plate, the vacuum nozzle is disposed on the base plate, and the second pump body is connected to the vacuum nozzle. The vacuum nozzle is used to adsorb the corresponding LED light panel.

[0014] In a further embodiment of this utility model, the adsorption device is externally connected to a vacuum solenoid valve, a solenoid valve vacuum and flow detection sensor, and a vacuum buffer. The vacuum nozzle, the external vacuum solenoid valve, the solenoid valve vacuum and flow detection sensor, and the vacuum buffer are connected in sequence through a pipeline.

[0015] In a further embodiment of this invention, a single-module controller is also included. This single-module controller is electrically connected to the pump controller, an external vacuum solenoid valve, a vacuum and flow detection sensor for the solenoid valve, the vacuum pressure sensor, the second pump body, and the motor. It is configured to control the second pump body based on the vacuum information obtained from the vacuum pressure sensor to ensure that the air pressure at the vacuum nozzle is reached. The external vacuum solenoid valve, the vacuum sensor, and the flow detection sensor maintain the air pressure at the vacuum nozzle after the second pump body stops or the air pressure at the vacuum nozzle is reached.

[0016] In a further embodiment of this utility model, the telescopic rotation device further includes a spring, which is sleeved on the telescopic rod.

[0017] In a further embodiment of this utility model, the horizontal plate and the vertical plate are provided with a plurality of heat dissipation holes, and each mounting slot is connected to any adjacent mounting slot through at least one of the heat dissipation holes.

[0018] Compared with related technologies, the LED screen installation and disassembly structure based on air suction provided by this utility model has the following advantages:

[0019] This invention uses an adsorption device to adsorb LED light boards, so that the connection between the LED light boards and the mounting plate is not affected by high temperature.

[0037] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0038] refer to Figures 1 to 9 This utility model provides an LED screen installation and disassembly structure based on air suction, characterized in that it includes: a mounting plate 500, multiple LED light panels 100, a single-module controller 300, an adsorption device 400, and a telescopic rotation device 200; the mounting plate 500 is equipped with multiple horizontal plates 610 and multiple vertical plates 620 to form multiple mounting slots 500A; each mounting slot 500A is provided with a single-module controller 300, at least one adsorption device 400, and at least one pair of telescopic rotation devices 200, and the single-module controller 300 in each mounting slot 500A is provided with... The device 300 controls the corresponding adsorption device 400, telescopic rotation device 200, and communicates with the corresponding LED light panel 100. The adsorption device 400 in each mounting slot 500A adsorbs one corresponding LED light panel 100. A pair of telescopic rotation devices 200 in each mounting slot 500A are detachably connected to both sides of the corresponding LED light panel 100. Each telescopic rotation device 200 is configured to drive the LED light panel 100 into or out of the mounting slot 500A when telescopic, and to lock the connection to the LED light panel 100 when rotating.

[0039] This invention utilizes the adsorption device 400 to adsorb the LED light panel 100, ensuring that the connection between the LED light panel 100 and the mounting plate 500 is not affected by high temperatures. This effectively overcomes the problem of magnet demagnetization during magnetic attraction, which affects the fixing effect of the LED light panel 100 due to the high temperature environment. The adsorption device 400 and the telescopic rotation device 200 provide a quick and convenient connection to the LED light panel 100. The adsorption device 400 only needs to absorb or supply air to install or remove the LED light panel 100, while the telescopic rotation device 200 only needs to extend and rotate or rotate and extend to install or remove the LED light panel 100. At the same time, the telescopic rotation device 200 can also lock the LED light panel 100.

[0040] In a further embodiment of this utility model, a motor 250 is mounted on the mounting plate 500; a cylinder 220 is mounted on the motor 250; and a telescopic rod 260 is partially disposed within the cylinder 220 and is controlled by the air pressure within the cylinder 220 to extend and retract. The telescopic rod 260 is detachably connected to the LED light panel 100 and is drively connected to the power output shaft of the motor 250.

[0041] In this solution, from the perspective of installation and disassembly efficiency, when installing the LED light panel 100, the motor 250 starts and drives the cylinder 220 to rotate, adjusting the telescopic rod 260 to a suitable angle. Then, the cylinder 220 drives the telescopic rod 260 to extend, accurately and quickly inserting it into the corresponding position on the LED light panel 100 and rotating to lock it for a detachable connection. The entire process is fast and greatly shortens installation time. During disassembly, the cylinder 220 first extends the telescopic rod 260, pulling the LED light panel 100 a certain distance from the mounting slot 500A. Then, the motor 250 drives the cylinder 220 to rotate again, disengaging the telescopic rod 260 from the LED light panel, achieving rapid disassembly. Compared to traditional methods, this operation greatly simplifies the installation and disassembly process and significantly improves work efficiency, especially in the installation and maintenance of large-scale LED screens, where its advantages are even more pronounced. Secondly, in terms of connection stability, the cooperation between the cylinder 220 and the telescopic rod 260 provides a reliable mechanical connection. The cylinder 220 can precisely control the extension and retraction length and force of the telescopic rod 260, ensuring a stable and secure connection between the telescopic rod 260 and the LED light panel. During the use of the LED screen, even if it is affected by external vibrations or impacts, the telescopic rod 260 can maintain a tight connection with the LED light panel under the action of the cylinder 220, without loosening or falling off, effectively ensuring the normal operation of the LED screen.

[0042] In a further embodiment of this utility model, a lock head 270 is provided on the telescopic rod 260, and a rotating lock groove is provided on the LED light panel 100. The motor 250 drives the lock head 270 to rotate and engage in the rotating lock groove, so that the telescopic rotation device 200 is locked and connected to the LED light panel 100.

[0043] In this design, from the perspective of connection stability, when locking the LED light panel is required, the motor 250 starts and precisely drives the telescopic rod 260 to rotate, allowing the locking head 270 on the telescopic rod 260 to accurately engage with the rotating locking groove on the LED light panel. This snap-fit ​​locking method, through the tight fit between the locking head 270 and the rotating locking groove, forms a reliable mechanical locking structure. Compared to ordinary connection methods, it greatly enhances the connection strength between the LED light panel 100 and the telescopic rotation device 200, effectively resisting various external interference forces, such as wind and vibration. Even in harsh operating environments, it ensures that the LED light panel 100 is firmly fixed in the mounting groove 500A, without shaking, shifting, or even falling off, thus guaranteeing the overall stability and display effect of the LED screen. In terms of installation convenience, this design greatly simplifies the locking connection process. When installing the LED light panel 100, the worker only needs to roughly place the LED light panel in the appropriate position of the mounting groove 500A, so that the lock head 270 is relatively close to the rotating lock groove. Then, by controlling the motor 250 to drive the telescopic rod 260 to rotate, the lock head 270 can automatically lock into the rotating lock groove, achieving quick locking. The disassembly process is the reverse. The entire process requires no complicated tools or cumbersome operating steps, and even non-professionals can complete it in a short time, greatly improving installation efficiency and reducing installation costs.

[0044] refer to Figure 7 In a further embodiment of this utility model, the telescopic rod 260 includes a moving rod 261 and a fixed rod 262. The fixed rod 262 is disposed on the power output shaft of the motor 250, and the moving rod 261 is movably connected to the fixed rod 262.

[0045] The fixed rod 262 is provided with an anti-deflection protrusion 2621, which extends along the axial direction of the telescopic rod 260; the moving rod 261 is provided with an anti-deflection groove 261A, which extends along the axial direction of the telescopic rod 260; the anti-deflection protrusion 2621 is engaged in the anti-deflection groove 261A.

[0046] In this design, during the operation of the telescopic rotation device 200, the telescopic rod 260 needs to perform precise axial telescopic movement within the cylinder 220 to achieve the installation and removal of the LED light panel 100. An anti-deflection protrusion 2621 extends axially along the telescopic rod 260 and engages with an anti-deflection groove 261A extending in the same direction within the moving rod 261. This structure effectively limits the radial deflection of the telescopic rod 260 within the moving rod 261 (mainly the offset caused by the rotation of the motor 250). When the cylinder 220 drives the telescopic rod 260 to extend or retract, the cooperation between the anti-deflection protrusion 2621 and the anti-deflection groove 261A ensures that the telescopic rod 260 can only move along a predetermined axial direction, avoiding inaccurate movement caused by radial offset during the extension and retraction process. For example, during the process of accurately inserting or pulling the LED light panel 100 into or out of the mounting slot 500A, this precise telescopic movement ensures that the LED light panel 100 and the mounting slot 500A are precisely aligned, improving the success rate of installation and disassembly, reducing the need for repeated adjustments due to positional deviations, and greatly improving work efficiency.

[0047] In a further embodiment of the present invention, the telescopic rotating device 200 further includes a first pump body 240 and a pump controller 230. The pump controller 230 is disposed on the first pump body 240 and electrically connected to the first pump body 240. The first pump body 240 is connected to the cylinder 220 to supply air to the cylinder 220.

[0048] In a further embodiment of this invention, the adsorption device 400 includes a base plate 410, a vacuum nozzle 430, and a second pump body 420. Both the base plate 410 and the second pump body 420 are mounted on the mounting plate 500. The vacuum nozzle 430 is mounted on the base plate 410. The second pump body 420 communicates with the vacuum nozzle 430, which is used to adsorb the corresponding LED light panel 100. The base plate 410 is connected to the mounting plate 500 through a first connecting hole 410A.

[0049] The second pump body 420 is connected to the vacuum nozzle 430 and is integrated on the mounting plate 500. This compact layout makes the operation of the entire adsorption device 400 extremely convenient. When installing the LED light panel 100, simply start the second pump body 420. The second pump body 420 works quickly, creating a negative pressure environment at the vacuum nozzle 430, thereby quickly adsorbing and fixing the corresponding LED light panel. The entire adsorption process requires no complicated operating steps or additional tools and can be completed in a short time, greatly shortening the installation time and improving installation efficiency. Similarly, when removing the LED light panel 100, simply turn off the second pump body 420 or reverse its operation and simultaneously run the telescopic rotation device 200 to release the negative pressure at the vacuum nozzle 430. The LED light panel 100 can then be easily detached, achieving rapid disassembly, which is very suitable for the rapid assembly and maintenance needs of large-scale LED screens.

[0050] In a further embodiment of this utility model, the adsorption device 400 is externally connected to a vacuum solenoid valve 450, a solenoid valve vacuum and flow detection sensor 460, and a vacuum buffer 440, and the vacuum nozzle 430 is connected in sequence through a pipe.

[0051] In a further embodiment of this invention, a single-module controller 300 is also included. The single-module controller 300 is electrically connected to the pump controller 230, the vacuum pressure sensor 470, the second pump body 420, and the motor 250. It is configured to control the second pump body 420 based on the vacuum information acquired by the vacuum pressure sensor 470 to ensure the air pressure of the vacuum nozzle 430. The external vacuum solenoid valve 450 and the solenoid valve vacuum and flow detection sensor 460 maintain the air pressure of the vacuum nozzle 430 after the second pump body 420 stops or reaches the air pressure of the vacuum nozzle 430. Furthermore, the single-module controller 300 can also be electrically connected to the displacement sensor 210 and the panel 130 controller.

[0052] In a further embodiment of this utility model, the telescopic rotation device 200 further includes a spring 280, which is sleeved on the telescopic rod 260.

[0053] In a further embodiment of this utility model, the horizontal plate 610 and the vertical plate 620 are provided with a plurality of heat dissipation holes 600A, and each mounting slot 500A is connected to any adjacent mounting slot 500A through at least one heat dissipation hole 600A. A heat dissipation groove 600B is also provided on the back of the mounting plate.

[0054] Furthermore, the LED light panel 100 is also provided with a nozzle groove 100A and a locking groove 100B for installation.

[0055] The invention may also include a communication module 110 for communicating with the outside world to obtain the content to be displayed. The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
