Description

Technical Field

[0001] This utility model belongs to the field of LRD display module technology, and more specifically, it relates to an edge-crack resistant LED display module. Background Technology

[0002] In the field of modern display technology, LED display modules are the core components for displaying images and information, and their performance directly affects the display effect and user experience. During installation, transportation, and daily use, the edges of LED display modules are highly susceptible to external impacts or vibrations, leading to cracking and damage. This not only affects display quality but also significantly shortens the module's lifespan and increases maintenance costs. Traditional LED display modules typically use only a simple frame structure to protect the display edges. These frames are mostly made of rigid materials, which, while providing some support, lack an effective cushioning mechanism. When subjected to external impacts, the rigid frame cannot absorb or disperse the impact force, causing the impact to act directly on the display edge, easily resulting in screen breakage. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides an edge-crack-resistant LED display module, which solves the technical problem in the prior art where the rigid frame of traditional LED display modules lacks a buffer mechanism, cannot effectively disperse impact force when subjected to external impact, and is prone to causing the display edge to crack.

[0004] The purpose and effect of this utility model of an edge-crack-resistant LED display module are achieved by the following specific technical means:

[0005] An edge-crack-resistant LED display module includes a display body. Two sets of first protective frames and two sets of second protective frames are respectively disposed around the periphery of the display body. The two sets of first protective frames are respectively secured to the top and bottom of the display body, and the two sets of second protective frames are respectively secured to both sides of the display body. Multiple sets of buffer corner pieces are disposed around the periphery of the display body, and these buffer corner pieces are respectively fitted onto the four corners of the display body. Each buffer corner piece is connected to one end of a first protective frame and a second protective frame. One side of each buffer corner piece is parallel to one side of a first protective frame, and the other side forms an outwardly protruding buffer surface.

[0006] According to an effective implementation, both the first protective frame and the second protective frame are provided with multiple sets of mounting rods, and the mounting rods are provided with multiple sets of positioning holes. A connecting rod is provided between the mounting rods and the opposing mounting rods. Positioning through holes are provided at both ends of the connecting rods, and positioning bolts are inserted into the positioning through holes and one of the positioning holes. A protective frame is formed between the two sets of the first protective frame and the two sets of the second protective frame, and the display screen body is fitted into the protective frame.

[0007] According to an effective implementation, multiple sets of mounting slots are provided on both the first protective frame and the second protective frame. Multiple sets of buffer bladders filled with cooling liquid are provided on one side of the display screen body. The buffer bladders are fitted into the mounting slots, and multiple sets of heat dissipation holes are provided in the mounting slots.

[0008] According to an effective embodiment, an elastic buffer pad is provided on the display screen body, and the elastic buffer pad is located between the display screen body and the first protective frame and the second protective frame; the elastic buffer pad is made of silicone material, and multiple sets of pressure-reducing grooves are formed on the elastic buffer pad.

[0009] According to one effective embodiment, the buffer corner piece has multiple sets of buffer grooves, the buffer grooves are hexagonal, and the buffer corner piece forms a honeycomb structure through the multiple sets of buffer grooves.

[0010] According to one effective embodiment, the buffer surface of the buffer corner piece is covered with a wear-resistant protective coating.

[0011] According to an effective embodiment, both the first protective frame and the second protective frame have an L-shaped cross-section, and an inwardly bent retaining edge is provided on the side near the display surface of the display body. The display body is secured between the retaining edge and the first or second protective frame.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. Two sets of first protective frames and two sets of second protective frames are secured around the perimeter of the display body, forming a surrounding protective frame. Combined with corner buffers at the four corners, this enhances the impact resistance of the module edges. When the module is impacted, the outward-protruding buffer surfaces of the corner buffers first come into contact with the force, dispersing and absorbing the impact through their internal honeycomb-shaped buffer groove structure, preventing the impact from being directly transmitted to the display edge. Simultaneously, the elastic buffer pads, made of silicone and featuring pressure-reducing grooves, are located between the display body and the protective frames, further buffering vibrations and reducing stress concentration, thereby significantly reducing the risk of display edge breakage.

[0014] 2. The internally filled cooling liquid buffer bladder, combined with the heat dissipation holes on the protective frame, forms a highly efficient heat exchange system. This system effectively removes heat generated during operation, preventing component aging and performance degradation due to overheating. The inward-bending edge design of the L-shaped protective frame enhances the mechanical connection between the display body and the protective frame, ensuring that the connections between components remain stable and reliable even under long-term use or frequent vibration. This design, integrating impact resistance, heat dissipation, and structural stability, comprehensively improves the reliability and lifespan of the LED display module while reducing maintenance costs.

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solution of this utility model, but should not be used to limit the scope of protection of this utility model.

[0023] Example:

[0024] like Figures 1 to 5As shown, this utility model provides an edge-crack-resistant LED display module, including a display body 11. Two sets of first protective frames 21 and two sets of second protective frames 22 are respectively arranged around the periphery of the display body 11. The display body 11 is fitted between the two sets of first protective frames 21 and two sets of second protective frames 22 and connected to the first and second protective frames 21 and 22 by adhesive. Simultaneously, multiple sets of buffer corner pieces 31 are arranged around the periphery of the display body 11, each set fitted onto one of the four corners of the display body 11. Each buffer corner piece 31 is connected to one end of a first protective frame 21 or a second protective frame 22. One side of the buffer corner piece 31 is parallel to one side of a first protective frame 21, while the other side forms an outwardly protruding buffer surface 32. When the module is subjected to external impact, especially at the corners, the buffer surface 32 of the buffer corner piece 31 contacts the external force first, dispersing the impact force and reducing the degree to which the impact force directly acts on the corners of the display body 11, thereby reducing the risk of corner breakage.

[0025] Both the first protective frame 21 and the second protective frame 22 are provided with multiple sets of mounting rods 23, and each mounting rod 23 has multiple sets of positioning holes 24. A connecting rod 25 is provided between the mounting rods 23 and their opposite counterparts. Positioning through holes 26 are provided at both ends of the connecting rod 25, and positioning bolts are inserted into the positioning through holes 26 and one of the positioning holes 24. A protective frame is formed between the two sets of first protective frames 21 and the two sets of second protective frames 22, and the display screen body 11 is secured within the protective frame. The mounting rods 23, positioning holes 24, connecting rods 25, positioning through holes 26, and positioning bolts cooperate with each other to ensure that the first protective frame 21 and the second protective frame 22 can be stably combined to form a robust protective frame. This protective frame provides external support for the display screen body 11. When the module is subjected to external pressure or impact, the protective frame can withstand part of the external force, preventing excessive pressure on the display screen body 11 and thus protecting it.

[0026] Both the first protective frame 21 and the second protective frame 22 have multiple sets of mounting slots 27. Multiple sets of buffer bladders 28 filled with cooling liquid are provided on one side of the display screen body 11. The buffer bladders 28 are secured within the mounting slots 27, and multiple sets of heat dissipation holes are formed within the mounting slots 27. During operation, the LED display screen generates heat. The cooling liquid in the buffer bladders 28 absorbs the heat emitted by the display screen body 11, thus cooling the display screen body 11 and preventing performance degradation or shortened lifespan due to overheating. The heat dissipation holes in the mounting slots 27 allow outside air to contact the buffer bladders 28, accelerating heat dissipation and ensuring the timely release of heat absorbed by the cooling liquid, maintaining a good cooling effect. Simultaneously, the buffer bladders 28 themselves have a certain degree of elasticity, providing cushioning against external forces and reducing direct impact on the display screen body 11.

[0027] An elastic buffer pad 33 is fitted onto the display screen body 11, located between the display screen body 11 and the first protective frame 21 and the second protective frame 22. The elastic buffer pad 33 is made of silicone and has multiple pressure-reducing grooves. The silicone elastic buffer pad 33 has good elasticity and flexibility. When the module is subjected to vibration or external impact, the elastic buffer pad 33 can deform to absorb and disperse the impact force, reducing the impact of vibration and impact on the display screen body 11. The presence of the pressure-reducing grooves allows the elastic buffer pad 33 more space to deform under stress, further enhancing its buffering effect, reducing the stress between the display screen body 11 and the protective frame, and preventing the edges of the display screen body 11 from cracking due to stress concentration.

[0028] like Figure 2 , Figure 4 As shown, the buffer corner piece 31 has multiple sets of buffer grooves 34, which are hexagonal in shape. The buffer corner piece 31 forms a honeycomb structure within these grooves. This honeycomb structure provides excellent mechanical properties; when the buffer corner piece 31 is subjected to external force, the hexagonal buffer grooves 34 effectively disperse and absorb the impact. This structure can transmit and disperse external force in multiple directions, preventing the impact from concentrating at a single point, thus allowing the buffer corner piece 31 to better protect the corners of the display screen body 11. Even under significant external impact, the honeycomb structure of the buffer corner piece 31 can dissipate the impact energy through its own deformation, reducing damage to the corners of the display screen body 11.

[0029] The buffer surface 32 on the buffer corner piece 31 is covered with a wear-resistant protective coating. During daily use of the module, the buffer surface 32 may rub or collide with external objects. The wear-resistant protective coating can increase the wear resistance of the buffer surface 32 and reduce the wear caused by friction. This ensures that the buffer corner piece 31 can maintain good buffering performance even after long-term use, continuously and effectively protecting the corners of the display screen body 11 and extending the service life of the module.

[0030] like Figure 2 , Figure 5 As shown, both the first protective frame 21 and the second protective frame 22 have L-shaped cross-sections, and an inwardly bent retaining edge 29 is provided on the side near the display surface of the display body 11. The display body 11 is secured between the retaining edge 29 and the first protective frame 21 or the second protective frame 22. The L-shaped protective frame, together with the inwardly bent retaining edge 29, forms a slot-like structure that securely holds the display body 11 within it. This structure can limit the display body 11 from multiple directions, preventing it from moving within the module. When the module is subjected to external force, the L-shaped protective frame and retaining edge 29 can better transfer the external force to the entire protective frame, enhancing the stability of the display body 11 installation and further protecting the display body 11 from external damage.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments.
