[0002] LED display screens usually include a box, a display module and a power box installed on the box, wherein the power box is used to supply power to the display module. Generally, in order to meet the waterproof requirements of LED display screens, such as outdoor LED display screens, the power box is not only required to have an independent waterproof function, but also required to meet the waterproof requirements when the power box is installed in the box.

[0003] In the related art, a position is reserved on the box for installing the power box. In order to achieve the purpose of waterproofing, a sealing ring is usually set between the power box and the box to seal and waterproof. However, the current sealing ring often adopts a rubber ring, that is, waterproofing is achieved by extrusion and deformation of the rubber ring. When in use, if the extrusion force on the rubber ring is uneven, the rubber ring cannot fit well on the contact surface between the box and the power box after being compressed and deformed, water leakage will occur, and water will enter the power box, thereby reducing the overall waterproof reliability of the LED display.

[0064] At present, with the rapid development of the LED industry, the rental of LED display screens is also extremely popular. There are more and more outdoor use scenarios for LED display screens. In order to fight against rain and wet and cold weather, LED display screens must have high waterproof capabilities to ensure the smooth progress of various activities.

[0065] In the related art, an LED display screen usually includes a box body, and a display module and a power box installed on the box body, wherein the power box is used to supply power to the display module. Generally, a position needs to be reserved on the box body for installing the power box. For the purpose of waterproofing, a sealing ring is usually provided between the power box and the box body for sealing and waterproofing. However, current sealing rings often use rubber rings, that is, waterproofing is achieved by extrusion and deformation of the rubber ring. During use, if the extrusion force on the rubber ring is uneven, the rubber ring cannot fit well on the contact surface between the box body and the power box after being compressed and deformed, and water leakage will occur, and water will enter the power box, thereby reducing the overall waterproof reliability of the LED display screen.

[0066] Based on this, an embodiment of the present application provides an LED display screen, which is used to block water by setting a first groove and a first surrounding edge around the outer side of a first sealing ring. External water must pass through the first groove and the first surrounding edge to contact the first sealing ring, thereby reducing the probability of water leakage of the first sealing ring 41 and improving the overall waterproof performance of the LED display screen.

[0067] Below, combined with the attached Figures 1 to 14 The LED display screen of the present application is described in detail with specific embodiments.

[0068] like Figures 1 to 4 As shown, an embodiment of the present invention provides an LED display screen, which includes a box 10, a display module 20 and a power box 30, wherein the display module 20 and the power box 30 are both installed on the box 10, as shown in FIG. Figure 1 shown.

[0069] In one embodiment, if Figure 2 , Figure 3 and Figure 4 As shown, a waterproof structure 40 is provided between the power box 30 and the case body 10, and the waterproof structure 40 includes a first sealing ring 41, a first groove 42 and a first surrounding edge 43. The first sealing ring 41 is clamped between the power box 30 and the case body 10, and the first surrounding edge 43 and the first groove 42 are arranged to surround and enclose the first sealing ring 41, and the first surrounding edge 43 is adapted to extend into the first groove 42.

[0070] The LED display screen provided by the embodiment of the utility model is provided with a first groove 42 and a first peripheral edge 43 around the outer side of the first sealing ring 41, and the first peripheral edge 43 extends into the first groove 42. In this way, the first peripheral edge 43 and the first groove 42 surround and enclose the first sealing ring 41, which is equivalent to providing a circle of water retaining structure around the outer side of the first sealing ring 41. External water can only contact the first sealing ring 41 through the first groove 42 and the first peripheral edge 43, thereby greatly reducing the probability of water leakage of the first sealing ring 41, which helps to improve the overall waterproof performance of the LED display screen.

[0071] It can be understood that in a specific embodiment, Figure 3 and Figure 4 As shown, the first sealing ring 41 is clamped between the power box 30 and the case 10, which means that when the power box 30 is stably installed in the case 10, the first sealing ring 41 is clamped by the power box 30 and the case 10, and the first sealing ring 41 can be squeezed and deformed by the clamping force, so that it fits tightly to the power box 30 and the case 10, thereby achieving sealing and waterproofing.

[0072] It can be understood that in a specific embodiment, Figure 2 , Figure 4 and Figure 5 As shown, the first surrounding edge 43 and the first groove 42 surround and enclose the first sealing ring 41, which means that the first surrounding edge 43 and the first groove 42 are both located outside the ring body of the first sealing ring 41, and the first surrounding edge 43 and the first groove 42 are both annular structures, the first surrounding edge 43 surrounds the first sealing ring 41, and the first groove 42 also surrounds the first sealing ring 41. In this way, the water retaining structure composed of the first groove 42 and the first surrounding edge 43 surrounds the first sealing ring 41, and the water retaining reliability of the water retaining structure is higher.

[0073] In another embodiment, if Figure 3 , Figure 4 and Figure 5 As shown, at least one of the box body 10 and the power box 30 is provided with a first groove 42, and the other of the box body 10 and the power box 30 is provided with a first surrounding edge 43. That is to say, one of the box body 10 and the power box 30 is provided with a first groove 42, and the other of the box body 10 and the power box 30 is provided with a first surrounding edge 43. For example, the first groove 42 is provided on the box body 10, and the first surrounding edge 43 is correspondingly provided on the power box 30, or the first groove 42 is provided on the power box 30, and the first surrounding edge 43 is correspondingly provided on the box body 10.

[0074] In this way, no matter on which component the first groove 42 and the first edge 43 are specifically set, they can achieve the purpose of water blocking. The setting positions of the first edge 43 and the first groove 42 are flexible and can be designed according to the actual conditions of the power box 30 and the box body 10, which is highly practical.

[0075] It should be noted that, in some embodiments, the number of the first groove 42 can be one, and correspondingly, the number of the first surround 43 can also be one. In this case, the first groove 42 can be set on the box body 10, and the corresponding first surround 43 is set on the power box 30, or the first groove 42 is set on the power box 30, and the first surround 43 is set on the box body 10.

[0076] In a specific embodiment, Figure 4 , Figure 5 box Figure 6 As shown, the first groove 42 is provided on the power box 30 , and the first surrounding edge 43 is provided on the box body 10 .

[0077] In other embodiments, the number of the first grooves 42 may be multiple, and correspondingly, the number of the first surrounding edges 43 may also be multiple and equal to the number of the first grooves 42. The multiple first grooves 42 are arranged at intervals on the outside of the first sealing ring 41, and the multiple first surrounding edges 43 extend into the multiple first grooves 42 one by one. In this way, multiple water retaining structures are arranged on the outside of the first sealing ring 41, and water is retained layer by layer, with a better water retaining effect.

[0078] In another embodiment, if Figure 3 , Figure 4 and Figure 6 As shown, the first groove 42 has a groove outer wall away from the first sealing ring 41, and the groove outer wall is provided with a first water guide port 421 connected to the first groove 42. The first water guide port 421 connected to the first groove 42 means that the first water guide port 421 is connected to the groove space of the first groove 42.

[0079] In this way, a first water guide port 421 is provided on the outer wall of the first groove 42, and the first water guide port 421 is communicated with the first groove 42, and the accumulated water in the first groove 42 can be discharged through the first water guide port 421. When encountering a heavy rain environment, even if some water enters the first groove 42, it can be discharged through the first water guide port 421, and there will be basically no accumulated water in the first groove 42, thereby further reducing the risk of water leakage of the first sealing ring 41 and improving the sealing effect of the first sealing ring 41.

[0080] In a specific embodiment, Figure 6 As shown, the first groove 42 is disposed on the power box 30 , and the first water guide port 421 is a notch disposed on the outer wall of the first groove 42 .

[0081] In another embodiment, if Figure 3 and Figure 4 As shown, the end of the first surrounding edge 43 facing the bottom of the first groove 42 abuts against the bottom of the first groove 42. In this way, the bottom of the first surrounding edge 43 is set to abut against the bottom of the first groove 42, that is, there is almost no gap between the first surrounding edge 43 and the bottom of the first groove 42, so that even if some water enters the first groove 42, it will be blocked by the first surrounding edge 43 and cannot flow through the first groove 42 to contact the first sealing ring 41, and the water blocking effect is better.

[0082] In another embodiment, if Figure 3 and Figure 4 As shown, the first groove 42 has an outer wall away from the first sealing ring 41 , and the outer wall of the groove abuts between the power box 30 and the box body 10 .

[0083] In this way, by setting the outer wall of the first groove 42 to abut between the power box 30 and the box body 10, that is, when the first groove 42 is set in the power box 30, the bottom end of the outer wall of the first groove 42 abuts against the box body 10, such as Figure 4 As shown, when the first groove 42 is provided in the box body 10, the bottom end of the outer wall of the first groove 42 abuts against the power box 30. In this way, the gap between the power box 30 and the box body 10 is blocked by the outer wall of the first groove 42, thereby further reducing the amount of water entering the first groove 42 and achieving a better water blocking effect.

[0084] In another embodiment, if Figure 2 , Figure 3 and Figure 4 As shown, the waterproof structure 40 further includes a second groove 44 , and the first sealing ring 41 is embedded in the second groove 44 .

[0085] By adopting the technical solution of this embodiment, a second groove 44 is provided to embed the first sealing ring 41, and the installation and positioning of the first sealing ring 41 is more precise, which can reduce the risk of sealing failure caused by sliding displacement of the first sealing ring 41. In addition, the first sealing ring 41 is compressed and deformed in the second groove 44, and the second groove 44 can provide the second sealing ring 50 with sufficient deformation space, which helps to improve the uniformity of the compression deformation of the second sealing ring 50, thereby improving the sealing and waterproof effect of the second sealing ring 50.

[0086] It should be noted that, in a specific embodiment, when the first sealing ring 41 is embedded in the second groove 44 , the first sealing ring 41 can be deformed to fit the groove wall of the second groove 44 after being squeezed, thereby achieving sealing.

[0087] In a specific embodiment, Figure 4 and Figure 5 As shown, the second groove 44 is provided in the box body 10, and the first sealing ring 41 is embedded in the box body 10. It can be understood that in other embodiments, the second groove 44 can also be provided in the power box 30, and the first sealing ring 41 is embedded in the power box 30. Regardless of whether the second groove 44 is specifically provided in the box body 10 or the power box 30, it is only necessary to satisfy that when the first sealing ring 41 is installed in the second groove 44 and the power box 30 is stably installed in the box body 10, the power box 30 and the box body 10 can cooperate to clamp the first sealing ring 41, so that the first sealing ring 41 can be close to the box body 10 and the power box 30, thereby achieving sealing and waterproofing.

[0088] In one embodiment, Figure 3 and Figure 4 As shown, the waterproof structure 40 also includes a second surrounding edge 45, which is arranged opposite to the second groove 44, and the end of the second surrounding edge 45 facing the second groove 44 abuts against the first sealing ring 41. When in use, the second surrounding edge 45 presses the second sealing ring 50, and the second sealing ring 50 is pressed tightly into the second groove 44, so that the second sealing ring 50 can achieve sealing and waterproofing.

[0089] In some embodiments, Figure 4 , Figure 7 and Figure 8As shown, the first sealing ring 41 is provided with an upper groove 412, the opening of the upper groove 412 is arranged to face away from the bottom of the second groove 44, and the second surrounding edge 45 can be adapted to extend into the upper groove to press the first sealing ring 41. In this way, the first sealing ring 41 is clamped between the bottom of the second groove 44 and the second surrounding edge 45, and the second surrounding edge 45 is pressed against the bottom of the upper groove 412 of the first sealing ring 41, and there is almost no gap between the second surrounding edge 45 and the first sealing ring 41 for water to pass through.

[0090] In some embodiments, Figure 4 , Figure 7 and Figure 8 As shown, the first sealing ring 41 is also provided with a lower groove 411, the opening of the lower groove 411 is arranged toward the bottom of the second groove 44, the opposite side walls of the lower groove 411 are respectively fitted with the opposite side walls of the second groove 44, and there is almost no water gap between the first sealing ring 41 and the groove wall of the second groove 44, and the second sealing ring 50 has a better sealing and waterproof effect.

[0091] In the related art, in order to meet the normal practical use of the display module 20, in addition to reserving positions on the box body 10 for installing the power box 30 and the display module 20 respectively, it is also necessary to reserve a data interface 11 on the box body 10 for routing the connecting lines between the power box 30 and the display module 20, so as to realize power supply and signal transmission between the power box 30 and the display module 20. In this way, the data interface 11 also needs to be sealed to realize the waterproofing of the data interface 11.

[0092] In one embodiment of the utility model, the LED display screen further includes a second sealing ring 50 sandwiched between the power box 30 and the box body 10, the box body 10 is provided with a data interface 11, the display module 20 is further provided with a third groove 21 around the data interface 11, and the second sealing ring 50 is embedded in the third groove 21. That is, by providing the second sealing ring 50 on the outside of the data interface 11 of the box body 10, the data interface 11 is waterproofly sealed.

[0093] In another embodiment, if Figure 3 , Fig. 9 and Fig.10 As shown, the box body 10 is further provided with a third peripheral edge 12 surrounding and enclosing the third groove 21 , and the end of the third peripheral edge 12 facing away from the box body 11 abuts against the display module 20 .

[0094] That is, the second sealing ring 50 is located inside the third surrounding edge 12. In this way, by setting the third surrounding edge 12 on the box body 10, the third surrounding edge 12 surrounds and encloses the third groove 21. In this way, it is equivalent to setting a circle of water retaining structure on the outer periphery of the second sealing ring 50. External water can only contact the second sealing ring 50 through the third surrounding edge 12, thereby greatly reducing the probability of water leakage of the second sealing ring 50, which is helpful to improve the overall waterproof performance of the LED display.

[0095] In some embodiments, Fig. 9 , 10 and Fig.11 As shown, the third surrounding edge 12 is further provided with a second water guide port 121 , which is connected to the inner space of the third groove 21 , wherein the second water guide port 121 is connected to the third groove 21 , which means that the second water guide port 121 is connected to the inner space of the third groove 21 .

[0096] In this way, by setting the second water guide port 121 in the third surrounding edge 12, the accumulated water in the third groove 21 can be discharged through the second water guide port 121. When encountering a heavy rain environment, even if some water enters the third groove 21, it can be discharged through the second water guide port 121. There will be basically no accumulated water in the third groove 21, thereby further improving the sealing effect of the second sealing ring 50.

[0097] In a specific embodiment, Fig. 9 As shown, the second water guide port 121 is a notch disposed on the outer wall of the third groove 21 .

[0098] In other embodiments, Fig.10 and Fig.11 As shown, a sleeve arm 211 is convexly provided at the bottom of the third groove 21, and the second sealing ring 50 is sleeved on the sleeve arm 211. The sleeve arm 211 is arranged in the third groove 21 for the second sealing ring 50 to be sleeved and installed, and the installation stability of the second sealing ring 50 is higher. In addition, the sleeve arm 211 can also play a role of water blocking, further improving the sealing and waterproofing ability of the second sealing ring 50.

[0099] In a specific embodiment, Fig.10 , Fig.11 and Fig.12 As shown, the second sealing ring 50 may be provided with a sleeve groove 51, and the sleeve arm 211 is inserted and sleeved in the sleeve groove 51, so that the sleeve of the second sealing ring 50 is installed on the sleeve wall.

[0100] In other embodiments, Fig. 9 , Fig.13 and Fig.14As shown, the second sealing ring 50 includes a main body 52 and an annular edge 53 protruding from the main body 52 . The main body 52 is embedded in the second groove 44 , and the annular edge 53 is located outside the third groove 21 and fits against the surface of the box body 10 .

[0101] In this way, the second sealing ring 50 is embedded in the second groove 44 through the main body 52. ​​On the one hand, the main body 52 is compressed and deformed to achieve sealing and waterproofing. On the other hand, the annular edge 53 is provided to fit with the surface of the box body 10, thereby further improving the sealing between the second sealing ring 50 and the box body 10 and improving the waterproof effect of the second sealing ring 50.

[0102] In a specific embodiment, Fig. 9 and Fig.14 As shown, the sleeve groove 51 is provided on the main body 52 .

[0103] In other embodiments, Fig. 9 , Fig.13 and Fig.14 As shown, along the outward direction of the third groove 21, that is, along Fig. 9 In the direction indicated by the middle arrow F, the annular edge 53 is in a gradually expanding trumpet shape.

[0104] In this way, the annular edge 53 is set to a trumpet shape. When the display module 20 is stably installed on the box body 10 and the box body 10 squeezes the second sealing ring 50, the trumpet-shaped annular edge 53 can better fit the surface of the box body 10, and the sealing and water-blocking performance is better.

[0105] In other embodiments, Figure 1 As shown, the LED display screen also includes a connection lock 60, and the power box 30 is locked and installed on the box body 10 through the connection lock 60. In this way, the power box 30 is locked to the box body 10 through the connection lock 60, and the connection lock 60 can provide sufficient locking force to lock the power box 30 to the box body 10, and can also make the power box 30 and the box body 10 have a sufficiently large clamping force to clamp the first sealing ring 41 and the second sealing ring 50, so that the extrusion deformation of the first sealing ring 41 and the second sealing ring 50 meets the sealing requirement, thereby improving the reliability of waterproofing.

[0106] Of course, in other embodiments, on the premise of meeting the installation requirements of the power box 30 and the requirements of the first sealing ring 41 and the second sealing ring 50 being compressed and deformed to achieve sealing, the power box 30 can also be connected to the box body 10 by other means such as screwing, riveting, and socket connection.
