Abstract

This invention relates to the field of LED display technology and discloses a waterproof LED display module, including a lamp board, a bottom shell, an LED display control panel, and a face mask. Adaptive sealing and monitoring components are provided at the bottom of the lamp board near the connection area between the lamp board and the bottom shell and the LED display control panel. An air supply component is installed in the middle area of ​​the bottom shell to provide air for heat dissipation inside the lamp board and to the adaptive sealing and monitoring components.

Description

Technical Field

[0001] This invention relates to the field of LED display technology, and more specifically to a waterproof LED display module, particularly a waterproof LED display module suitable for immersive display scenarios in the metaverse. Background Technology

[0002] With the rise of the metaverse concept, virtual reality, augmented reality, and large-scale immersive display systems have placed higher demands on the reliability and environmental adaptability of LED displays. Outdoor or semi-outdoor metaverse display terminals need to be exposed to complex environments for a long time, and problems such as rainwater infiltration and loose connections have become the main factors affecting display stability. Existing LED display modules typically consist of a three-layer structure: a mask, a lamp board, and a base shell, which are fixed together by screws or clips. In actual use, due to thermal expansion and contraction, vibration, or aging, tiny gaps or partial loosening can easily appear at the connection points between the three components. On the one hand, rainwater or moisture can seep in through the gaps, causing short circuits in the lamp board or damage to the LEDs. On the other hand, the loosening of the connection points will further exacerbate the sealing failure, creating a vicious cycle. To address the aforementioned issues, some existing technologies employ methods such as overall potting or adding sealing rings to improve waterproofing performance. However, these methods are difficult to disassemble and repair after potting, and the sealing rings are prone to aging and failure under long-term pressure. More importantly, most existing solutions are passive seals, unable to actively monitor whether the connection has become loose or detached, and even less able to automatically apply compensating sealing force when detachment occurs. Therefore, there is an urgent need for a waterproof LED display module to solve the aforementioned technical problems. Summary of the Invention

[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a waterproof LED display module to solve the problems existing in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a waterproof LED display module, comprising a lamp board, a bottom shell being sequentially installed on the top and bottom of the lamp board, wherein a face shield is installed on the bottom of the LED display control panel to protect the display area of ​​the face shield, adaptive sealing and monitoring components are provided on the bottom of the lamp board near the connection area between the lamp board and the bottom shell and the LED display control panel, and an air source supply component is installed in the middle area of ​​the bottom shell to provide the air source required for heat dissipation to the inside of the lamp board and to provide the air source required for the adaptive sealing and monitoring components; The adaptive sealing and monitoring assembly includes a transmission plate. Each set of transmission plates is sequentially arranged on the inner side near the connection between the lamp plate and the bottom shell, and on the inner side near the connection between the lamp plate and the LED display control panel. A push rod is movably sleeved on the inner wall of one end of each set of transmission plates near the corresponding connection position. An annular rubber plate is installed on one end of the push rod. The same set of first springs is installed perpendicularly to the opposite face of the push rod and the transmission plate. A first air groove is opened on the inner side of one end of the push rod. A sensing column is slidably connected to the inner side of the first air groove near the annular rubber plate. The interior of the first air groove and the annular rubber plate are mutually circulated. The same set of second springs is installed perpendicularly to the opposite face of the sensing column and the first air groove. Sensors are installed on both sides of the first air groove away from the sensing column. A second countersunk groove is opened on the inner wall of the other end of the push rod. Gas is mutually circulated between the second countersunk groove and the first air groove. After the light panel, base shell, LED display control panel, and faceplate are installed, the air supply component is activated, inputting compressed air into the adaptive sealing and monitoring component. This drives the annular rubber plate to press against the connection point and create negative pressure. The internal pressure of the annular rubber plate increases, pushing the sensing column to contact the sensor. When there is a leak at the connection point, the internal pressure of the annular rubber plate decreases, the sensing column detaches from the sensor, and the sensor sends a detachment signal to the control module inside the LED display control panel, triggering the reminder mode.

[0005] Preferably, a first torsion spring sealing mechanism is provided on the inner side of the first gas groove near the second countersunk groove to control the flow direction of the gas inside the second countersunk groove. The sensing column has a first countersunk groove inside to facilitate gas flow between the first air groove and the annular rubber plate. The upper surface of the sensing column near the first countersunk groove is provided with a second torsion spring sealing mechanism to control the gas flow direction inside the first air groove.

[0006] Preferably, the lamp plate has an annular air groove inside near the position of each group of transmission plates, and a conveying pipe is installed on the side of each group of transmission plates. One end of the conveying pipe extends into the interior of the corresponding annular air groove. The transmission plate, the conveying pipe and the interior of the transmission plate are in a state of mutual gas flow, and the installation position of the conveying pipe is far away from the push rod.

[0007] Preferably, the first torsion spring sealing mechanism includes a first sealing plate, wherein the first sealing plate is movably installed inside the second countersunk groove at one end near the first air groove, wherein a first U-shaped plate is installed on the side of the first sealing plate, and a first torsion spring assembly is installed at the end of the first U-shaped plate away from the first sealing plate, wherein the preload provided by the first torsion spring assembly causes the first sealing plate to adhere to the inner side of one end of the second countersunk groove.

[0008] Preferably, the second torsion spring sealing mechanism includes a second sealing plate, wherein the second sealing plate is movably installed on the inner wall of the first countersunk groove at the end away from the position of the second spring, wherein a second U-shaped plate is installed on the side of the second sealing plate, and a second torsion spring assembly is installed at the end of the second U-shaped plate away from the position of the second sealing plate, wherein the preload provided by the second torsion spring assembly causes the second sealing plate to adhere to the inner side of one end of the first countersunk groove. The lamp panel has limit grooves on the inner sides of all four sides near the bottom shell and the face mask, and each set of limit grooves is equipped with an anti-loosening sealing mechanism.

[0009] Preferably, the anti-loosening sealing mechanism includes a first anti-loosening plate and a second anti-loosening plate, which are sequentially and movably sleeved in two adjacent sets of limiting grooves.

[0010] Preferably, the lamp panel has an annular auxiliary air groove inside near each set of limiting grooves, and a push plate is movably sleeved inside each set of annular auxiliary air grooves. The end of each set of push plates away from the corresponding annular auxiliary air groove is installed on the side of the first anti-falling plate or the second anti-falling plate.

[0011] Preferably, a third spring is vertically mounted on the other end of the push plate, and the end of the third spring away from the push plate is vertically mounted on the inner side of the annular auxiliary air groove.

[0012] Preferably, the air source supply component includes a base and a protective cover. The base is welded to the bottom of the inner side of the bottom shell, the protective cover is movably installed on the top of the base, and a miniature air pump is installed inside the base. A multi-hole pipe is installed at the air outlet of the miniature air pump.

[0013] Preferably, the porous tube includes three sets of air outlets: the first set of air outlets is equipped with a heat dissipation pipe installed at the bottom of the base; the second set of air outlets is equipped with two sets of first air delivery pipes, which are respectively located inside two sets of annular air grooves; and the third set of air outlets is equipped with two sets of second air delivery pipes, which are respectively located inside two sets of annular auxiliary air grooves.

[0014] The technical effects of this invention include at least one of the following: This invention, by setting an adaptive sealing and monitoring component, can automatically sense and send a detachment signal when a leak occurs at the connection point, and at the same time use compressed air to reverse the flow of moisture from the leak point, preventing water vapor from entering the module and improving waterproof reliability. After a leak occurs, the present invention activates the air supply component through the control module, which drives the first sealing plate and the second torsion spring sealing mechanism to open in sequence, and directs compressed air to the leak point to continuously purge for 60-90 seconds, effectively removing moisture and impurities at the connection and preventing repeated leaks. The present invention also includes an anti-loosening sealing mechanism. After the adaptive sealing and monitoring components have been working for a period of time, compressed air pushes the first anti-loosening plate and the second anti-loosening plate into contact with each other to form a frame-shaped protective component. This applies additional pressure to the connection to prevent the detachment from worsening, while the rubber layer enhances the sealing effect. Attached Figure Description

Detailed Implementation

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The waterproof LED display module involved in the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0019] Reference Figures 1 to 10 As shown, the present invention provides a waterproof LED display module, including a lamp board 1, a bottom shell 2 and an LED display control panel 3 are installed sequentially on the top and bottom of the lamp board 1, wherein a face shield 4 is installed on the bottom of the LED display control panel 3 to protect the display area of ​​the face shield 4; An adaptive sealing and monitoring component 5 is provided at the bottom of the lamp panel 1 near the connection area between the lamp panel 1 and the bottom shell 2 and the LED display control panel 3. An air supply component 7 is installed in the middle area of ​​the bottom shell 2 to provide the air supply required for heat dissipation to the inside of the lamp panel 1 and to the adaptive sealing and monitoring component 5. The adaptive sealing and monitoring assembly 5 includes a transmission plate 502. Each set of transmission plates 502 is sequentially arranged on the inner side near the connection between the lamp plate 1 and the bottom shell 2, and on the inner side near the connection between the lamp plate 1 and the LED display control panel 3. A push rod 503 is movably sleeved on the inner wall of one end of each set of transmission plates 502 near the corresponding connection position. An annular rubber plate 501 is installed on one end of the push rod 503. The same set of first springs 505 are installed perpendicularly to the opposite surface of the push rod 503 and the transmission plate 502. A first air groove is formed on the inner side of one end of the push rod 503. 506, wherein a sensing post 511 is slidably connected to the inner side of the first air groove 506 near the annular rubber plate 501, and the interior of the first air groove 506 and the annular rubber plate 501 are mutually circulated. The same set of second springs 508 are installed perpendicularly to the opposite surfaces of the sensing post 511 and the first air groove 506. Sensors 507 are installed on both sides of the first air groove 506 away from the sensing post 511. A second countersunk groove 512 is opened on the inner wall of the other end of the push rod 503, wherein gas is mutually circulated between the second countersunk groove 512 and the first air groove 506. After the lamp panel 1, base shell 2, LED display control panel 3, and faceplate 4 are installed, the air supply component 7 is activated, inputting compressed air into the adaptive sealing and monitoring component 5, driving the annular rubber plate 501 to press against the connection, creating a negative pressure adsorption between it and the connection. The internal pressure of the annular rubber plate 501 increases, pushing the sensing column 511 to contact the sensor 507. When the connection leaks, the internal pressure of the annular rubber plate 501 decreases, and the sensing column 511 detaches from the sensor 507. The sensor 507 sends a detachment signal to the control module inside the LED display control panel 3, triggering the reminder mode. At the same time, the control module responds to the reset of the sensing column 511 and activates the air supply component 7, using compressed air to expel moisture from the leak point.

[0020] In this embodiment, after the lamp board 1, the bottom shell 2, the LED display control panel 3, and the mask 4 are installed, the air supply component 7 is activated, inputting a certain amount of compressed air into the transmission plate 502, driving each set of push rods 503 and the annular rubber plate 501 to move towards the connection between the lamp board 1 and the bottom shell 2 or the connection between the lamp board 1 and the LED display control panel 3, until each set of annular rubber plates 501 contacts the corresponding connection position. At this time, under the push of the push rod 503, the annular rubber plate 501 is in a compressed state, and a negative pressure environment is generated between the annular rubber plate 501 and the connection, which is used to help fix the connection between the two. At the same time, the pressure inside the annular rubber plate 501 increases, thereby driving the sensing column 511 to move towards the sensor 507, until the sensing column 511 contacts the sensor 507. When a leak occurs at the connection, a gap is created between the annular rubber plate 501 at the corresponding position and the connection, causing a decrease in the internal pressure of the annular rubber plate 501. Under the action of the preset spring force of the second spring 508, the sensing column 511 is disengaged from the sensor 507. The sensor 507 then sends a detachment signal to the control module inside the LED display control panel 3, triggering the reminder mode. At the same time, when the sensing column 511 resets, it drives the compressed air inside the first air groove 506 and the annular rubber plate 501 to move towards the leak point at the connection, expelling the moisture accumulated inside the annular rubber plate 501 from the leak point.

[0021] As a supplement, the sensor 507 is a miniature contact pressure sensor or a micro switch (e.g., a miniature micro switch of model DM-100 or a flexible thin-film pressure sensor, which are common electronic components in the art and belong to the prior art). The sensor 507 is fixedly installed on both sides of the inner wall of the first air groove 506, with its sensing surface facing the direction of movement of the sensing column 511.

[0022] Initial state (good sealing): When compressed air is supplied into the annular rubber plate 501 by the air supply component 7, the internal air pressure of the annular rubber plate 501 increases, pushing the sensing column 511 to move towards the sensor 507 against the elastic force of the second spring 508. When the end of the sensing column 511 contacts the sensing surface of the sensor 507 and applies a certain pressure, the resistance value or switching state inside the sensor 507 changes (for example, from normally open to closed, or the resistance value changes from high resistance to low resistance), thereby generating a contact signal.

[0023] Leakage condition (sealing failure): When a leak occurs at the connection, the internal air pressure of the annular rubber plate 501 drops, and the elastic force of the second spring 508 pushes the sensing post 511 to move away from the sensor 507 to reset. The sensing post 511 disengages from the sensing surface of the sensor 507, causing the resistance value or switching state of the sensor 507 to return to its initial state (e.g., from closed to normally open, or the resistance value to change from low resistance to high resistance), thereby generating a "disengagement signal".

[0024] This embodiment, through the above structure, realizes real-time monitoring of the sealing status of the connection, and automatically issues an alarm signal and reverses the discharge of water when leakage occurs, thereby improving the waterproof reliability and intelligence of the LED display module. The substrate of the lamp board 1 is made of a high-performance ceramic substrate, such as an aluminum nitride substrate or an aluminum oxide substrate. This material has good thermal conductivity, which helps the LED chip dissipate heat. It also has good heat resistance and dimensional stability, and will not affect the normal operation of the mechanical mechanisms in this embodiment.

[0025] Reference Figures 1 to 11As shown, the present invention provides a waterproof LED display module. A first torsion spring sealing mechanism 509 is provided on the inner side of the first air groove 506 near the second countersunk groove 512 to control the flow direction of the gas inside the second countersunk groove 512. The sensing column 511 has a first countersunk groove 5110 inside, which is used to help the first air groove 506 and the annular rubber plate 501 to maintain gas flow. The upper surface of the sensing column 511 near the first countersunk groove 5110 is provided with a second torsion spring sealing mechanism 510, which is used to control the gas flow direction inside the first air groove 506.

[0026] An annular air groove 102 is provided inside the lamp plate 1 near the position of each group of transmission plates 502. A conveying pipe 504 is installed on the side of each group of transmission plates 502. One end of the conveying pipe 504 extends into the interior of the corresponding annular air groove 102. The transmission plate 502, the conveying pipe 504 and the interior of the transmission plate 502 are in a state of mutual gas flow. The installation position of the conveying pipe 504 is far away from the push rod 503. The first torsion spring sealing mechanism 509 includes a first sealing plate 5091, wherein the first sealing plate 5091 is movably installed inside one end of the second countersunk groove 512 near the first air groove 506, wherein a first U-shaped plate 5092 is installed on the side of the first sealing plate 5091, and a first torsion spring assembly 5093 is installed at the end of the first U-shaped plate 5092 away from the first sealing plate 5091, wherein the preload provided by the first torsion spring assembly 5093 causes the first sealing plate 5091 to adhere to the inner side of one end of the second countersunk groove 512.

[0027] In this embodiment, the preload provided by the first torsion spring assembly 5093 is greater than the spring force provided by the second spring 508, so that the compressed air supplied by the air source supply assembly 7 can be delivered to the bottom of the push rod 503 through the delivery pipe 504, which can drive the push rod 503 to move outward first.

[0028] The second torsion spring sealing mechanism 510 includes a second sealing plate 5101, wherein the second sealing plate 5101 is movably installed on the inner wall of the first countersunk groove 5110 at a position away from the second spring 508, wherein a second U-shaped plate 5102 is installed on the side of the second sealing plate 5101, and a second torsion spring assembly 5103 is installed at the end of the second U-shaped plate 5102 away from the second sealing plate 5101, wherein the preload provided by the second torsion spring assembly 5103 causes the second sealing plate 5101 to adhere to the inner side of one end of the first countersunk groove 5110.

[0029] In this embodiment, when the compressed air inside the annular rubber plate 501 moves to the outer surface of the second sealing plate 5101, because the second sealing plate 5101 is movably engaged with the inner side of one end of the first countersunk groove 5110, the compressed air cannot drive the second sealing plate 5101 to rotate clockwise. Only when the compressed air inside the first countersunk groove 5110 reaches the rated value can the second sealing plate 5101 be driven to rotate clockwise. When the control module triggers the detachment signal, it activates the air supply component 7 to generate a large amount of compressed air, which is input to the transmission plate 502 through the annular air groove 102 and the delivery pipe 504. This compressed air drives the first spring 505 to stretch to its maximum length. When the internal pressure of the transmission plate 502 and the second countersunk groove 512 reaches the rated value, it drives the first sealing plate 5091 to rotate and open, delivering the compressed air inside the transmission plate 502 and the second countersunk groove 512 to the first air groove 506 and the first countersunk groove 5110. When the internal pressure of the first countersunk groove 5110 reaches the rated value, it drives the second torsion spring sealing mechanism 510 to rotate clockwise, delivering the compressed air inside the first countersunk groove 5110 to the annular rubber plate 501 and the leakage point at the connection, in order to help remove moisture and impurities inside the annular rubber plate 501 and the leakage point. This process lasts for 60-90 seconds.

[0030] The lamp panel 1 has limiting grooves 603 on its inner sides near the bottom shell 2 and the faceplate 4. Each limiting groove 603 has an anti-loosening sealing mechanism 6 inside. The anti-loosening sealing mechanism 6 includes a first anti-detachment plate 601 and a second anti-detachment plate 602. The first anti-detachment plate 601 and the second anti-detachment plate 602 are sequentially and movably sleeved in the two adjacent limiting grooves 603. The lamp panel 1 has an annular auxiliary air groove 604 inside near each limiting groove 603. A push plate 605 is movably sleeved inside each annular auxiliary air groove 604. One end of each push plate 605 away from the corresponding annular auxiliary air groove 604 is installed on the side of the first anti-detachment plate 601 or the second anti-detachment plate 602. A third spring 606 is vertically installed on the other end of the push plate 605. The end of the third spring 606 away from the push plate 605 is vertically installed on the inner side of the annular auxiliary air groove 604.

[0031] In this embodiment, both the first anti-fall plate 601 and the second anti-fall plate 602 are covered with a rubber layer.

[0032] After the control module triggers the detachment signal and the adaptive sealing and monitoring component 5 operates for 60-90 seconds, the air supply component 7 inputs compressed air into the corresponding annular auxiliary air groove 604. This compressed air drives each set of push plates 605, the first anti-detachment plate 601, and the second anti-detachment plate 602 to move towards the outer surface of the bottom shell 2 or the face mask 4 until the corresponding two sets of first anti-detachment plates 601 and second anti-detachment plates 602 come into contact with each other, forming a frame-shaped protective component that wraps around the leakage point at the connection to assist in sealing the leakage point. At the same time, additional compressive force is applied to the connection between the bottom shell 2 and the lamp plate 1 or the connection between the mask 4 and the lamp plate 1 to prevent the connection from falling off and further deteriorating.

[0033] The air supply component 7 includes a base 703 and a protective cover 701. The base 703 is welded to the bottom of the inner side of the bottom shell 2. The protective cover 701 is movably installed on the top of the base 703. A miniature air pump 702 is installed inside the base 703. A perforated pipe 706 is installed at the air outlet of the miniature air pump 702. The porous tube 706 includes three sets of air outlets: the first set of air outlets is equipped with a heat dissipation tube 707, which is installed at the bottom of the base 703; the second set of air outlets is equipped with two sets of first air delivery tubes 704, which are respectively located inside the two sets of annular air grooves 102; and the third set of air outlets is equipped with two sets of second air delivery tubes 705, which are respectively located inside the two sets of annular auxiliary air grooves 604.

[0034] In this embodiment, the LED display control panel 3 is equipped with a temperature sensing component to sense the temperature change inside the lamp panel 1. The lamp panel 1 has a heat dissipation hole 101 on its side, and a waterproof and ventilated membrane is installed inside the heat dissipation hole 101. When the temperature sensing component determines that the lamp panel 1 is in a high-temperature condition, it controls the micro air pump 702 to start and delivers gas into the lamp panel 1 through the first set of air outlets of the multi-hole pipe 706 and the heat dissipation pipe 707. The gas inside the lamp panel 1 is discharged to the outside through the heat dissipation hole 101. Through the above steps, the gas circulation inside the lamp panel 1 is accelerated, so as to facilitate the heat dissipation operation inside the lamp panel 1. The waterproof and breathable membrane is made of expanded polytetrafluoroethylene (ePTFE), which has a microporous structure that allows gas to pass through while preventing liquid water from entering.

[0035] Reference Figures 1 to 11 As shown, the waterproof LED display module of the present invention is suitable for outdoor or semi-outdoor LED displays in the metaverse immersive display scenario, and its working process is as follows: Installation: After the light panel 1, base shell 2, LED display control panel 3 and faceplate 4 are installed, the air supply component 7 is started to input compressed air into the adaptive sealing and monitoring component 5; Compressed air drives each set of push rods 503 and annular rubber plate 501 to move towards the connection between lamp plate 1 and bottom shell 2 and the connection between lamp plate 1 and LED display control panel 3, until the annular rubber plate 501 contacts and presses against the connection, forming a negative pressure environment to assist in fixing the connection. At the same time, the internal pressure of the annular rubber plate 501 increases, pushing the sensing column 511 to move to the contact sensor 507, completing the initial state setting. Leakage detection: When a leak occurs at the connection, a gap is created between the annular rubber plate 501 and the connection, and the internal pressure decreases. Under the preset elastic force of the second spring 508, the sensing column 511 is disengaged from the sensor 507. The sensor 507 then sends a detachment signal to the control module inside the LED display control panel 3, triggering the reminder mode. Drainage: When the sensing column 511 is reset, it drives the compressed air inside the first air groove 506 and the annular rubber plate 501 to move towards the leak point at the connection, and discharges the water accumulated inside the annular rubber plate 501 from the leak point to the outside. After the control module triggers the detachment signal, it starts the air supply component 7 to generate a large amount of compressed air, which is input to the transmission plate 502 through the annular air groove 102 and the delivery pipe 504. The compressed air drives the first spring 505 to stretch to its maximum length. When the internal pressure of the transmission plate 502 and the second countersunk groove 512 reaches the rated value, it drives the first sealing plate 5091 to rotate and open, and delivers the compressed air to the first air groove 506 and the first countersunk groove 5110. When the internal pressure of the first countersunk groove 5110 reaches the rated value, it drives the second torsion spring sealing mechanism 510 to rotate clockwise, and delivers the compressed air to the annular rubber plate 501 and the leakage point for 60-90 seconds to help remove moisture and impurities. Anti-loosening seal: After a leak occurs and the adaptive sealing and monitoring component 5 has been working for 60-90 seconds, the air supply component 7 inputs compressed air into the annular auxiliary air groove 604, driving the push plate 605, the first anti-loosening plate 601 and the second anti-loosening plate 602 to move towards the outer surface of the bottom shell 2 or the face shield 4. The first anti-loosening plate 601 and the second anti-loosening plate 602 come into contact with each other to form a frame-shaped protective component, which wraps around the leak point and applies additional extrusion force to the connection to prevent the detachment from worsening. The rubber layer laid on the outside of the first anti-loosening plate 601 and the second anti-loosening plate 602 can enhance the sealing effect. Heat dissipation: The temperature sensing component inside the LED display control panel 3 senses the temperature change inside the lamp board 1. When high temperature occurs, it controls the micro air pump 702 to start and deliver gas into the lamp board 1 through the first set of air outlets of the porous tube 706 and the heat dissipation pipe 707. The gas inside the lamp board 1 is discharged to the outside through the heat dissipation hole 101, which accelerates the gas flow and achieves heat dissipation.
