[0002] With the development of technology, LED display screens have been widely used in many occasions due to their high brightness, long lifespan and other characteristics. However, LED display screens used outdoors often face the influence of natural factors such as sand, wind, rain and snow, as well as human factors such as accidental impacts. These factors may cause damage to the screen, thus shortening the service life and increasing the maintenance cost. In order to improve the stability and reliability of LED display screens in harsh environments, the industry has been constantly exploring new design solutions and technical means to enhance the durability of products.

[0003] Currently, the common methods on the market to strengthen the resistance of LED display screens to external impacts mainly include increasing the frame thickness, using high-strength materials to make the housing, etc. Although increasing the frame thickness can improve the compressive strength to a certain extent, it also makes the whole device bulky and difficult to carry; while using high-strength materials faces the problem of high cost. When subjected to external impacts, the housing often cannot effectively buffer the external force, resulting in the internal circuit board and LED light strips directly bearing the impact force. LED light strips are extremely precise components, and the chips and circuits inside are prone to damage after being impacted. Summary of the Invention

[0022] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0023] Embodiment: Please refer to the attached Figure 1 - attached Figure 6 、attached Figure 8 ,The embodiment of the present invention provides an impact-resistant LED display module, including a scratch-resistant coating 1. One side of the scratch-resistant coating 1 is provided with a panel 3. The outer wall of the panel 3 is provided with a frame 2. The inner wall of the frame 2 is provided with an energy-absorbing pad 13. One side of the energy-absorbing pad 13 is provided with a backplane 11. The inside of the backplane 11 is provided with a plurality of grooves. A plurality of heat dissipation holes 9 are provided in the grooves of the backplane 11. A heat dissipation mechanism is provided in the grooves of the backplane 11. One side of the heat dissipation mechanism is arranged on the side wall of the energy-absorbing pad 13. A buffer device is provided on one side of the energy-absorbing pad 13.

[0024] Specifically, the outermost scratch-resistant coating 1 adheres to the surface of the panel 3. The special chemical material of the panel 3 itself effectively resists the scratching risks that may be brought about by wiping, collision, etc. in daily use scenarios. The panel 3 is firmly installed inside the frame 2. The frame 2, as the basic framework of the module, not only provides structural support for the internal components, but also the energy-absorbing pad 13 attached to the inner wall of the frame 2 can effectively resist impact. When the module encounters external impact, such as when an outdoor billboard is impacted by foreign objects carried by strong winds or collides during equipment handling, the impact force first acts on the frame 2, and the frame 2 evenly distributes and transfers the force to the energy-absorbing pad 13. The energy-absorbing pad 13 uses its own elastic material characteristics to quickly compress and deform, absorbing a large amount of impact energy and reducing the initial impact force. The backplane 11 is located on one side of the energy-absorbing pad 13, providing support for the rear part of the module. There are a plurality of grooves inside the backplane 11, and heat dissipation holes 9 are evenly distributed in the grooves. The heat dissipation mechanism is arranged in the grooves and is connected to the side wall of the energy-absorbing pad 13 at one side. During the operation of the module, the heat dissipation mechanism works to drive air flow. The outside cold air enters the grooves through the heat dissipation holes 9, taking away the heat of the backplane 11 and surrounding components. The backplane 11 is made of aluminum, which has good heat conduction performance, and the hot air is then discharged from other ventilation openings, forming a heat dissipation cycle.

[0025] Through the cooperation of the energy-absorbing pad 13 and the frame 2, the impact resistance toughness of the module is enhanced. It effectively avoids the problem that internal precision components such as LED strips 18 and PCB boards 16 are damaged when suffering from impact, ensuring that the display screen can still stably display images in complex and changeable environments, improving the overall reliability and stability. It solves the problem of poor impact resistance performance of traditional LED display modules. When the module is impacted by external forces, the internal components are easily damaged, resulting in frequent problems with the display screen, and ensures continuous normal operation.

[0026] Please refer to the attached Figure 3 - Attachment Figure 5 , the buffer device includes a first silica gel pad 19. One side of the first silica gel pad 19 is arranged on the side wall of the energy absorption pad 13, and a spring 20 is arranged on the other side of the first silica gel pad 19. A silica gel tube 15 is arranged in the middle of the spring 20, and a second silica gel pad 23 is arranged at the other end of the spring 20.

[0027] Specifically, when the module is subjected to an external impact, the impact force is first transmitted to the frame 2, and the frame 2 causes the connected energy absorption pad 13 to start compressing and deforming, and the energy absorption pad 13 initially absorbs part of the impact energy. Immediately afterwards, the first silica gel pad 19 in direct contact with the side wall of the energy absorption pad 13 receives the remaining impact force. Since the material of the first silica gel pad 19 is soft and elastic, it can evenly disperse the impact force and smoothly transmit it to the spring 20. When the spring 20 is stressed instantaneously, it contracts according to its own elastic characteristics to slow down the impact force. At the same time, the silica gel tube 15 located in the middle of the spring 20 plays an auxiliary buffering role. The silica gel tube 15 uses the damping characteristics of its own silica gel material to generate friction when the impact force passes through, further consuming the impact energy, and cooperating with the spring 20 to weaken the impact force, protecting the internal components from being damaged by strong impacts.

[0028] The buffer device composed of the first silica gel pad 19, the spring 20, the silica gel tube 15 and the second silica gel pad 23 operates in coordination with the energy absorption pad 13, reducing the risk of damage to the internal precision components caused by external impact forces, effectively avoiding damage and failures of these components, ensuring that the display screen can still display images normally after being impacted, significantly enhancing the overall stability and reliability of the module, and enabling it to adapt to more complex and harsh usage environments. It solves the problem of the imperfect buffer protection mechanism of traditional LED display screen modules, effectively resists external impacts, ensures the continuous and stable operation of the display screen in complex environments, and reduces the maintenance cost and usage risk.

[0029] Please refer to the attached Figure 1 , Attachment Figure 3 - Attachment Figure 4 , a PCB board 16 is arranged on one side of the second silica gel pad 23, a heat-conducting silica gel sheet 17 is arranged on one side of the PCB board 16, the outer wall of the PCB board 16 is arranged on the inner wall of the frame 2, several LED light strips 18 are arranged on the side wall of the PCB board 16, one side of the heat-conducting silica gel sheet 17 is arranged on the outer wall of the LED light strip 18, the outer wall of the heat-conducting silica gel sheet 17 is arranged on the inner wall of the frame 2, one end of the LED light strip 18 is provided with a panel 3, an anti-scratch coating 1 is arranged on one side of the panel 3, and the anti-scratch coating 1 and the outer wall of the panel 3 are arranged on the inner wall of the frame 2.

[0030] Specifically, the second silicone pad 23 is located at the end of the buffer device. When an external impact force is transmitted to the second silicone pad 23 after being buffered by the energy absorption pad 13 and the buffer device, the second silicone pad 23 receives and disperses the impact force, and transmits the remaining tiny impact force to the PCB board 16 in contact with it, thus protecting the PCB board 16 from being affected by a large impact to the greatest extent. As a load-bearing component, the PCB board 16 is provided with a number of LED light strips 18 on its side wall. The LED light strips 18 will generate light for displaying images after being powered on. At the same time, heat will be generated when the LED light strips 18 are working. The heat-conducting silicone sheet 17 located between the outer wall of the LED light strips 18 and one side of the PCB board 16 starts to play a role. With its good heat-conducting performance, the heat-conducting silicone sheet 17 can conduct the heat generated by the LED light strips 18 to the PCB board 16, and the heat then diffuses to the surroundings through the PCB board 16. The outer wall of the PCB board 16 is arranged on the inner wall of the frame 2. The frame 2 not only provides physical support and a relatively fixed position for the PCB board 16, but also protects the PCB board 16 to a certain extent, preventing it from being damaged due to direct exposure caused by accidental collisions from the outside. Moreover, one end of the LED light strip 18 is close to the panel 3, and the light can pass through the panel 3 and the anti-scratch coating 1 covering one side of the panel 3 to display the image content outward. The anti-scratch coating 1 plays a role in preventing the panel 3 from being scratched during this process, ensuring the clarity and uniformity of the light transmission.

[0031] Through the high-efficient heat-conducting performance of the heat-conducting silicone sheet 17, the heat generated by the LED light strips 18 can be conducted out in time, avoiding the local accumulation of heat in the LED light strips 18, so that the heat can be more evenly distributed on the PCB board 16 and other relevant parts inside the module. Cooperating with the heat dissipation mechanism, it can effectively maintain the components inside the module working in a relatively suitable temperature environment, ensuring the luminous performance and service life of the LED light strips 18 and the stability of the display effect. It solves the problem that the heat of the LED light strips 18 in the traditional module is difficult to be effectively conducted out, which easily causes local overheating, accelerates the aging of components, affects the luminous efficiency and display effect, ensures the timeliness and effectiveness of the module heat dissipation, and extends the service life of the components.

[0032] Please refer to the attached Figure 1 - attached Figure 3 , reinforcing plates 4 are symmetrically and fixedly arranged at the bottom end of the frame 2, a fixing column 5 is fixedly arranged at the bottom end of the reinforcing plate 4, a bottom plate 6 is arranged at the bottom end of the fixing column 5, and telescopic devices are symmetrically arranged at the bottom end of the inner wall of the frame 2.

[0033] Specifically, the frame 2 serves as the external support frame of the entire LED display module. The reinforcement plates 4 symmetrically and fixedly arranged at the bottom end thereof extend vertically downward from the main body of the frame 2. The reinforcement plates 4 are fixed to the frame 2 by high-strength bolts, increasing the force-bearing area and structural strength of the frame 2 at the bottom. The bottom ends of the reinforcement plates 4 are also fixedly connected with fixing columns 5 by a stable connection process. The fixing columns 5 are columnar structures that vertically conduct the weight of the upper module downward. The bottom plate 6 provided at the bottom end of the fixing column 5 is made of a metal plate with a relatively large area and a certain thickness, enabling the bottom plate 6 to be in full contact with the placement plane and evenly dispersing the concentrated load transmitted by the fixing column 5 to the ground. When the module is subjected to external forces, such as the horizontal thrust of strong winds, the impact force generated by accidental collisions, and the vibration during handling, the force is first transmitted to the frame 2. Due to the collaborative support of the reinforcement plates 4, the fixing columns 5, and the bottom plate 6, these external forces can be effectively resisted, preventing the module from tilting, shaking, or even toppling due to unstable bottom.

[0034] The overall rigidity and stability of the module are improved through the reinforcement plates 4, the fixing columns 5, and the bottom plate 6. This not only effectively protects the internal precision components such as the LED light strips 18 and the PCB boards 16 from damage caused by shaking and toppling but also ensures the stable output of the display screen image, avoiding abnormal situations such as screen jitter and flicker, and guaranteeing the normal use function of the module. The problem of the weak bottom structure and inconvenient installation of the traditional LED display module is solved. The combined design of the reinforcement plates 4, the fixing columns 5, and the bottom plate 6 provides a solid bottom foundation for the module, enabling it to better adapt to various harsh conditions, reducing the failure rate, and improving the reliability of the product.

[0035] Please refer to the attached Figure 1 - attached Figure 4 、 attached Figure 6 - attached Figure 7 , the telescopic device includes an electric push rod 8. The outer wall of the electric push rod 8 is arranged at the bottom end of the inner wall of the frame 2. The output end of the electric push rod 8 is provided with a hinge block one 14. The middle of the hinge block one 14 is rotatably connected with a rotating shaft two 21. The rotating shaft two 21 penetrates through the hinge block one 14 and is rotatably connected with a hinge block two 22. One end of the hinge block two 22 is fixedly provided with a rain shield 7. The top side wall of the rain shield 7 is rotatably connected to the inner top wall of the frame 2 through a rotating shaft one 10.

[0036] Specifically, when the environment where the module is located faces rainfall or is in a humid condition, the control system will send a start command to the electric push rod 8. The electric push rod 8 is installed at the bottom end of the inner wall of the frame 2, and its outer wall fits with the inner wall of the frame 2 to ensure firmness and stability. After receiving the command, the motor of the electric push rod 8 operates to push the telescopic rod inside to extend. The front end of the telescopic rod is connected to the first hinge block 14, so that the first hinge block 14 moves outward as the telescopic rod moves. The middle part of the first hinge block 14 is rotatably connected to the second hinge block 22 through the second rotating shaft 21. This structural design enables the second hinge block 22 to rotate around the second rotating shaft 21 when the first hinge block 14 moves. One end of the second hinge block 22 is fixed with the rain shield 7, and the top side wall of the rain shield 7 is also rotatably connected to the inner top wall of the frame 2 by means of the first rotating shaft 10. Therefore, during the rotation of the second hinge block 22, the rain shield 7 starts to rotate downward and unfold with the first rotating shaft 10 as the axis. With the continuous push of the electric push rod 8, the rain shield 7 gradually covers one side of the back plate 11, blocking the heat dissipation holes 9 to prevent rainwater from entering through the heat dissipation holes 9, forming an effective rain-blocking protection barrier. When the rain stops or rain protection is not required, the control system drives the electric push rod 8 again to contract its telescopic rod, driving the movement of each hinge component, and the rain shield 7 rotates upward and retracts to return to the initial state, without affecting the normal display and ventilation and heat dissipation of the module.

[0037] Through the cooperation of the electric push rod 8 with the first hinge block 14 and the second hinge block 22 to drive the unfolding and retracting actions of the rain shield 7, the module has a reliable self-protection ability when facing rainy weather. It can effectively prevent rainwater from entering the interior, avoiding electrical faults such as short circuits and corrosion caused by rainwater infiltration, and ensuring that the display screen can still operate safely and stably in a humid environment. It solves the problem that traditional LED display modules cannot prevent rain outdoors, reduces the failure risk caused by rainwater, and improves the reliability and durability of the product.

[0038] Please refer to the attached Figure 3 - attached Figure 4 、attached Figure 6 、attached Figure 8 , the heat dissipation mechanism includes a motor 12. One side of the motor 12 is arranged on one side of the energy absorption pad 13. The output end of the motor 12 is provided with a fan blade 24. The outer wall of the motor 12 is provided with a fan frame 25. The fan blade 24 is arranged inside the fan frame 25.

[0039] Specifically, when the LED display module starts and enters the working state, the system powers on, causing the motor 12 to start running synchronously. The motor 12 is placed on one side of the energy-absorbing pad 13. This contact not only ensures the structural compactness but also utilizes the buffering characteristics of the energy-absorbing pad 13 to reduce the impact of vibrations that may be generated during the operation of the motor 12 on other components. As the motor 12 rotates at high speed when powered on, its output end drives the fan blade 24 to rotate rapidly. The fan blade 24 is exquisitely encapsulated inside the fan frame 25. On the one hand, the fan frame 25 provides a solid support structure for the fan blade 24, ensuring that the fan blade 24 remains stable during high-speed rotation and will not deviate from the axis due to centrifugal force or collide with surrounding components; on the other hand, the fan frame 25 defines the direction of the air flow and guides the air to flow along the preset path. Under the high-speed rotation of the fan blade 24, an obvious air pressure difference is formed inside the module. Driven by the pressure difference, the cold air from the outside continuously floods into the module through the heat dissipation holes 9 designed on the backplane 11. These cold air rapidly flows through the heat-generating components such as the LED light strip 18 and the PCB board 16, absorbing and carrying away the heat. The hot air is pushed by the air flow formed by the continuous rotation of the fan blade 24, and follows the ventilation channels reserved inside the module, and finally is discharged to the external environment. In this way, the heat inside the module is continuously taken out, maintaining a suitable temperature environment.

[0040] In terms of optimizing the heat dissipation performance, by virtue of the stable and efficient operation of the motor 12 driving the fan blade 24, an active heat dissipation system inside the module is constructed. It ensures that a large amount of heat generated during the continuous lighting of the LED light strip 18 can be timely dissipated, avoiding the local accumulation of heat and causing the LED light strip 18 to overheat. For the PCB board 16, a stable and suitable temperature environment guarantees the stable performance of various electronic components on it, effectively controls the problems of accelerated aging and solder joint loosening caused by high temperature, reduces the maintenance frequency of failures caused by overheating, and greatly improves the reliability and durability of the module. It solves the problem of insufficient heat dissipation capacity of traditional LED display modules. By cooling with air, the module is in a normal temperature environment, ensuring the stability of the module during long-term operation and reducing the use cost and maintenance difficulty.

[0041] Working principle: In terms of shock resistance, the scratch-resistant coating outside the panel prevents scratches, the energy-absorbing pads inside the frame compress and deform to absorb energy when impacted, and the silica gel pads and springs in the buffer device further weaken the impact force to protect the internal components. When dissipating heat, the motor starts to drive the fan blades to rotate within the fan frame, forming an air pressure difference, so that the outside cold air enters through the heat dissipation holes, flows through the heating elements to take away the heat and then discharges. In terms of protection, the reinforcement plate, fixed columns and bottom plate at the bottom end of the frame enhance the bottom stability and resist external forces. When it rains, the electric push rod pushes the hinge block, causing the rain shield to rotate and unfold around the rotating shaft, and it retracts after the rain stops. Through these principles, the module achieves stable operation in complex environments, effectively solves problems such as poor shock resistance, poor heat dissipation, and insufficient installation protection of the display screen, extends the service life, and improves the reliability.
