LED display module with anti-collision bump protection

Abstract

This invention discloses an LED display module with anti-collision raised dot protection, relating to the field of LED display modules. It includes a mounting frame, with a first telescopic rod fixedly connected to the top of the mounting frame. The output end of the first telescopic rod is fixedly connected to a display panel. When the display panel is impacted and squeezed, the first telescopic rod and a first spring compress, simultaneously triggering a trigger switch. The telescopic drive immediately operates, moving the display panel away from the impacting object. Simultaneously, the raised dot tube presses against the impacting object. At the same time, a transmission mechanism activates, moving the raised dot tube upwards. Once exposed, the raised dot tube not only directly blocks external impacts but also pushes the impacting object away, preventing its tip from continuously pressing against the LED chips. This dual protection effectively prevents impacts to the LED chips on the display panel surface, greatly improving the lifespan of the LED chips and the reliability of the display module.

Description

Technical Field

[0001] This invention relates to LED display module technology, specifically to an LED display module with anti-collision bump protection. Background Technology

[0002] LED display modules, as important information display devices, are widely used in various fields such as advertising, stage performances, and monitoring and command. In practical use, LED display modules often face complex and changing environments, with collisions being a particularly prominent issue that severely impacts their performance and lifespan.

[0003] Regarding impacts, LED display modules are typically installed in conspicuous and easily accessible locations, making the display panels highly susceptible to impact and pressure in scenarios with frequent personnel activity or accidental collisions. Existing LED display modules lack effective anti-collision protection mechanisms. When impacted, the impacting object may directly contact and damage the LED chips on the display panel surface. As the core light-emitting element of an LED display module, damage to the LED chips not only affects the display effect, causing defects such as black spots and bright spots, but in severe cases, it can even render the entire display module malfunctioning. Furthermore, replacing damaged LED chips or the display module requires time and cost, increasing the difficulty of equipment maintenance and operating costs.

[0004] In summary, existing LED display modules have significant shortcomings in terms of impact resistance, and a new technical solution is urgently needed to address these issues in order to improve the reliability and lifespan of LED display modules. Summary of the Invention

[0005] The purpose of this invention is to provide an LED display module with anti-collision bump protection to solve the problem of the lack of an effective anti-collision protection mechanism in the prior art, which leads to a reduction in the service life of the LED display module.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an LED display module with anti-collision bump protection, comprising a mounting frame, a first telescopic rod fixedly connected to the top of the mounting frame, a display panel fixedly connected to the output end of the first telescopic rod, a first spring fixedly sleeved on the outer surface of the first telescopic rod and fixedly connected to the mounting frame, a plurality of through slots opened on the display panel, a plurality of transmission tubes provided on the mounting frame, the plurality of transmission tubes being fixedly connected to each other by connecting blocks, a tension rod fixedly connected to the top of the mounting frame, the output end of the tension rod being fixedly connected to the bottom of the transmission tube, a second spring fixedly sleeved on the outer surface of the tension rod and fixedly connected to the mounting frame, and a convex top tube slidably connected to the through slots fixedly connected to the top of the transmission tube;

[0007] A telescopic drive component is fixedly connected to the top of the mounting frame. The output end of the telescopic drive component is fixedly connected to the bottom of the display panel. A second telescopic rod is fixedly connected to the top of the mounting frame. A trigger switch is fixedly connected to the output end of the second telescopic rod. A third spring, which is fixedly connected to the mounting frame, is fixedly sleeved on the outer surface of the second telescopic rod. A trigger block is fixedly connected to the bottom of the display panel. The telescopic drive component is electrically connected to the trigger switch via a wire.

[0008] The bottom of the display panel is connected to the connecting block via a transmission mechanism, which is used to drive the connecting block and the transmission tube to move upward.

[0009] Furthermore, the transmission mechanism includes a first transmission rack fixedly connected to the bottom of the display panel, a transmission gear rotatably connected to the mounting frame on one side of the first transmission rack, and a second transmission rack fixedly connected to the connecting block on the outer surface of the transmission gear.

[0010] Furthermore, the outer surface of the convex top tube is provided with multiple air holes, the outer surface of the transmission tube is fixedly connected to a first connecting pipe through a pipe, and the outer surface of the first connecting pipe is fixedly connected to a second connecting pipe. By installing a hair dryer on the display screen mounting bracket, the output end of the hair dryer is then connected to the second connecting pipe through a pipe.

[0011] Furthermore, the air blowing hole is provided with an inclined groove.

[0012] Furthermore, an installation ring is fixedly connected to the outer surface of the convex top tube, and a rubber sealing ring is fixedly connected to the top of the installation ring.

[0013] Furthermore, an alarm is fixedly connected to the mounting frame, and the alarm is electrically connected to a trigger switch via a wire. A reset switch is provided on the mounting frame, and the reset switch is electrically connected to the trigger switch via a wire, and the reset switch and the trigger switch are connected in parallel via a wire.

[0014] Furthermore, the rubber sealing ring is made of silicone rubber, and the cross-sectional shape of the rubber sealing ring is trapezoidal.

[0015] Furthermore, an adjustable mounting foot is threadedly connected to one side of the mounting frame, and an electromagnet block is fixedly connected to one side of the mounting foot.

[0016] Compared with the prior art, the LED display module with anti-collision bump protection provided by the present invention has the following beneficial effects:

[0017] When the display panel is impacted and squeezed, the first telescopic rod and the first spring compress, and simultaneously the trigger block activates the trigger switch. The telescopic drive immediately operates, moving the display panel away from the impacting object. At the same time, the convex top tube holds the impacting object in place. Simultaneously, the transmission mechanism activates, moving the convex top tube upwards. Once exposed, the convex top tube not only directly blocks the external impacting object but also pushes it away, preventing the sharp point of the impacting object from continuously pressing against the LED chips. This dual protection effectively prevents impacting objects from damaging the LED chips on the display panel surface, greatly improving the lifespan of the LED chips and the reliability of the display module. It reduces repair and replacement costs caused by collisions and ensures the stable operation of the display module in various complex environments.

[0018] When dust removal is required, press the display panel evenly to expose the raised tube from the through slot, ensuring the rubber sealing ring on the mounting ring seals tightly against the through slot to prevent dust from entering. A blower is installed on the display mounting bracket, and its output is connected to the second connecting pipe. Air flows sequentially through the second connecting pipe, the first connecting pipe, and the transmission pipe into the raised tube, finally exiting from the air outlet. The inclined groove within the air outlet changes the airflow direction, directing the air downwards towards the display panel surface, achieving automatic dust removal. This function eliminates the need for manual cleaning, saving manpower and time, maintaining the cleanliness of the display panel at all times, ensuring clear and stable display effects, and enhancing the user experience.

Detailed Implementation

[0028] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0029] Example 1

[0030] Please see Figures 1 to 6 As shown, the present invention provides an LED display module with anti-collision bump protection, including a mounting frame 1, a first telescopic rod 2 fixedly connected to the top of the mounting frame 1, a display panel 3 fixedly connected to the output end of the first telescopic rod 2, a first spring 4 fixedly sleeved on the outer surface of the first telescopic rod 2 and fixedly connected to the mounting frame 1, a plurality of through slots 5 opened on the display panel 3, a plurality of transmission tubes 6 provided on the mounting frame 1, the plurality of transmission tubes 6 being fixedly connected to each other by connecting blocks 7, a tension rod 8 fixedly connected to the top of the mounting frame 1, the tension rod consisting of a sleeve and an output rod, the output rod being inserted into the sleeve, the output rod 8 being able to only be stretched upwards and unable to move downwards when in the initial position, the output end of the tension rod 8 being fixedly connected to the bottom of the transmission tube 6, a second spring 9 fixedly sleeved on the outer surface of the tension rod 8 and fixedly connected to the mounting frame 1, and a convex top tube 10 slidably connected to the through slots 5 fixedly connected to the top of the transmission tube 6;

[0031] A telescopic drive component 11 is fixedly connected to the top of the mounting frame 1. The telescopic drive component 11 is an electric telescopic rod. The output end of the telescopic drive component 11 is fixedly connected to the bottom of the display panel 3. A second telescopic rod 12 is fixedly connected to the top of the mounting frame 1. A trigger switch 13 is fixedly connected to the output end of the second telescopic rod 12. A third spring 14, which is fixedly connected to the mounting frame 1, is fixedly sleeved on the outer surface of the second telescopic rod 12. A trigger block 15 is fixedly connected to the bottom of the display panel 3. The telescopic drive component 11 is electrically connected to the trigger switch 13 through a wire.

[0032] The bottom of the display panel 3 is connected to the connecting block 7 via a transmission mechanism, which is used to drive the connecting block 7 and the transmission tube 6 to move upward.

[0033] The transmission mechanism includes a first transmission rack 21 fixedly connected to the bottom of the display panel 3. A transmission gear 22 rotatably connected to the mounting frame 1 is meshed on one side of the first transmission rack 21. A second transmission rack 23 fixedly connected to the connecting block 7 is meshed on the outer surface of the transmission gear 22.

[0034] When the display panel 3 is impacted, it is compressed, causing it to move. The first telescopic rod 2 and the first spring 4 are compressed, and simultaneously, the display panel 3 moves the trigger block 15, which presses against the trigger switch 13. The trigger switch 13 then activates the telescopic drive component 11, which moves the display panel 3 away from the impacting object. Simultaneously, the convex top tube 10 is exposed, blocking the impact and preventing it from damaging the LEDs on the display panel 3. This also occurs during the downward movement of the display panel 3. In the process, the display panel 3 moves downward via the first transmission rack 21, which drives the transmission gear 22 to rotate. The transmission gear 22 drives the second transmission rack 23 to move upward, which in turn drives the transmission tube 6 to move upward. The transmission tube 6 then drives multiple convex top tubes 10 to move upward. These multiple convex top tubes 10 push against external impacts, preventing the tip of the impact from always contacting the LED beads on the display panel 3. This further improves the resistance to external impacts and effectively prevents external impacts from hitting the LED beads on the surface of the display panel 3, thus enhancing the protection of the LED beads on the surface of the display panel 3.

[0035] An alarm 51 is fixedly connected to the mounting frame 1. The alarm 51 is electrically connected to the trigger switch 13 via a wire. A reset switch is provided on the mounting frame 1. The reset switch is electrically connected to the trigger switch 13 via a wire, and the reset switch and the trigger switch 13 are connected in parallel. When the trigger switch 13 is activated, the alarm 51 will sound a buzzer to promptly remind the staff to perform maintenance. At this time, the staff will promptly remove the obstruction and remove the display module from the display screen mounting bracket. Then, the reset switch will be pressed to return the telescopic drive component 11 to its initial position. The display module will then be installed on the display screen mounting bracket.

[0036] One side of the mounting frame 1 is threaded with an adjustable mounting foot, and one side of the mounting foot is fixedly connected with an electromagnet block. The adjustable mounting foot facilitates the leveling of the display module. After leveling, the module is attached to the display screen mounting bracket by the electromagnet block on the mounting foot.

[0037] Example 2

[0038] Based on Example 1, please refer to Figures 2 to 6As shown, the outer surface of the convex top tube 10 is provided with multiple air holes 31. The outer surface of the transmission tube 6 is fixedly connected to the first connecting tube 32 through a pipe. The outer surface of the first connecting tube 32 is fixedly connected to the second connecting tube 33. The hair dryer can be fixedly installed on the display screen mounting bracket, and then the output end of the hair dryer is connected to the second connecting tube 33 through a pipe. The hair dryer is existing technology, so it will not be described in detail here.

[0039] An inclined groove 34 is provided inside the air blowing hole 31.

[0040] An installation ring 41 is fixedly connected to the outer surface of the convex top tube 10, and a rubber sealing ring 42 is fixedly connected to the top of the installation ring 41. The rubber sealing ring 42 is made of silicone rubber and has a trapezoidal cross-sectional shape.

[0041] When dust accumulates in the grooves between the LED beads on the surface of the display panel 3, the display panel 3 is first pressed evenly, and then moved so that the convex tube 10 is exposed from the through groove 5 on the display panel 3. At the same time, the rubber sealing ring 42 on the mounting ring 41 on the surface of the convex tube 10 is tightly sealed with the through groove 5 to achieve a seal on the through groove 5 and prevent dust from entering from the through groove 5 during subsequent dust blowing. Then, the blower on the mounting bracket is turned on, and the blower introduces gas into the second connecting pipe 33. The second connecting pipe 33 supplies gas to multiple transmission pipes 6 through the first connecting pipe 32. The transmission pipes 6 supply gas to multiple convex tubes 10. The convex tubes 10 blow the gas out through the air blowing hole 31. Then, the gas blows out through the air blowing hole 31 and at the same time, it changes the direction of the blown air downward through the inclined groove 34 in the air blowing hole 31, thereby blowing the dust downward onto the surface of the display panel 3, thus automatically cleaning the dust on the surface of the display panel 3.

[0042] Working principle:

[0043] Anti-collision protection principle

[0044] Collision triggering stage: When the display panel 3 collides with another object, it is squeezed and moves, at which point the first telescopic rod 2 and the first spring 4 are compressed. At the same time, the display panel 3 drives the trigger block 15 to move, and the trigger block 15 presses against the trigger switch 13, activating the trigger switch 13.

[0045] During the movement phase of display panel 3: the trigger switch 13 starts the telescopic drive component 11 (electric telescopic rod) to work, and the telescopic drive component 11 drives the display panel 3 to move, so that the display panel 3 is away from external collision objects.

[0046] Convex tube 10 blocking stage: During the movement of the display panel 3, the display panel 3 moves downward through the first transmission rack 21. The first transmission rack 21 drives the transmission gear 22 to rotate. The transmission gear 22 drives the second transmission rack 23 to move upward. The second transmission rack 23 drives the transmission tube 6 to move upward. The transmission tube 6 drives multiple convex tubes 10 to move upward and protrude from the through groove 5 on the display panel 3. The convex tubes 10 block external impacts to prevent them from hitting the LED beads on the display panel 3. The multiple convex tubes 10 push the external impacts to prevent the tip of the impacts from always pressing against the LED beads on the display panel 3, further improving the blocking effect against external impacts and effectively protecting the LED beads on the surface of the display panel 3.

[0047] Alarm Reminder Principle: An alarm 51 is fixedly connected to the mounting frame 1, and the alarm 51 is electrically connected to the trigger switch 13 via a wire. When the trigger switch 13 is activated, the alarm 51 is simultaneously activated, emitting a buzzing sound to alert the staff to perform maintenance. The staff promptly removes the obstruction, removes the display module from the display screen mounting bracket, and then triggers the trigger switch 13 to return the telescopic drive component 11 to its initial position. The display module is then installed on the display screen mounting bracket.

[0048] Installation and leveling principle: One side of the mounting frame 1 is threaded with an adjustable mounting foot, and an electromagnet block is fixedly connected to one side of the mounting foot. The display module can be leveled by adjusting the mounting foot, and after leveling, it is attached to the display screen mounting bracket by the electromagnet block on the mounting foot for installation.

[0049] Automatic dust removal principle

[0050] Sealing preparation stage: When dust accumulates in the groove between the LED beads on the surface of the display panel 3, press the display panel 3 evenly. The display panel 3 moves so that the convex tube 10 is exposed from the through groove 5 on the display panel 3. At the same time, the rubber sealing ring 42 on the mounting ring 41 on the surface of the convex tube 10 is tightly sealed with the through groove 5 to prevent dust from entering from the through groove 5 during subsequent dust blowing.

[0051] Gas delivery stage: A blower is fixedly installed on the display screen mounting bracket. The output end of the blower is connected to the second connecting pipe 33 through a pipe. Gas is supplied to the second connecting pipe 33. The second connecting pipe 33 supplies gas to multiple transmission pipes 6 through the first connecting pipe 32. The transmission pipes 6 then supply gas to multiple convex top pipes 10.

[0052] Dust removal stage: The convex top tube 10 blows out gas through the air hole 31. The gas changes direction through the inclined groove 34 in the air hole 31 and blows dust downwards onto the surface of the display panel 3, thereby automatically removing dust from the surface of the display panel 3.

[0053] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
