[0033] More specifically, the hollowed-out light panel 5 includes multiple rows of third hollowed-out portions 14 located in the middle. The third hollowed-out portions 14 correspond to the second hollowed-out portions 12. The third hollowed-out portions 14 are used to reduce the weight of the hollowed-out light panel 5. More specifically, the third hollowed-out portions 14 are horizontally extending round-headed strip-shaped through holes corresponding to the second hollowed-out portions 12. The hollowed-out light panel 5 is a square plate as a whole. The upper, lower, left, right, front, and rear surfaces of the square plate, as well as the hole walls of each third hollowed-out portion 14, are all coated with a vacuum nano waterproof membrane.

[0034] More specifically, the hollowed-out bottom shell 6 includes a fourth hollowed-out portion 15, a fifth hollowed-out portion 33, a slot 16, a magnet slot, and a screw slot. The fourth hollowed-out portion 15 and the fifth hollowed-out portion 33 are arranged longitudinally in an alternating pattern. The fourth hollowed-out portion 15 corresponds to the first hollowed-out portion 11, and the fifth hollowed-out portion 33 corresponds to the second hollowed-out portion 12. Under the action of the slot 16 and the hook 13, the hollowed-out light panel 5 is fixed between the hollowed-out mask 4 and the hollowed-out bottom shell 6. The hollowed-out bottom shell 6 uses a magnet to engage with the magnet slot and a screw to engage with the screw slot to further lock the hollowed-out lamp plate 5 between the hollowed-out bottom shell 6 and the hollowed-out mask 4. The fourth hollowed-out part 15 and the fifth hollowed-out part 33 are both used to reduce the weight of the hollowed-out bottom shell 6. More specifically, the fourth hollowed-out part 15 is a horizontally extending round-headed strip-shaped through hole corresponding to the first hollowed-out part 11, and the fifth hollowed-out part 33 is a horizontally extending square-headed strip-shaped through hole corresponding to the second hollowed-out part 12.

[0035] Specifically, the box frame assembly also includes a middle fixing lock 17, a quick-locking mechanism for the upper and lower handles 18, a telescopic positioning pin 19, and left and right locking mechanisms. The middle fixing lock 17, the quick-locking mechanism for the upper and lower handles 18, and the telescopic positioning pin 19 are located at the upper and lower parts of the frame body 3 to connect two adjacent frame bodies 3. The left and right locking mechanisms are located at the left and right sides of the frame body 3 to connect two adjacent frame bodies 3.

[0036] More specifically, the left and right sides of the frame body 3 are respectively a 45-degree beveled left side wall 20 and a 45-degree beveled right side wall 21. The left and right locking components include a 45-degree left locking component 22 and a 45-degree right locking seat 23. The 45-degree left locking component 22 is provided on the 45-degree beveled left side wall 20, and the 45-degree right locking seat 23 is provided on the 45-degree beveled right side wall 21. The 45-degree left locking component 22 corresponds one-to-one with the 45-degree right locking seat 23 on the adjacent frame body and locks to support the right-angle splicing of two adjacent LED outdoor displays.

[0037] In some specific embodiments, as in the locking and splicing method of a 45-degree left seat lock base and a 45-degree right seat lock piece in a hollowed-out arc-shaped LED outdoor display screen as described in patent CN221960681U, the 45-degree oblique cut left side wall 20 and the 45-degree oblique cut right side wall 21 refer to the 45-degree angle between the left and right sides of the frame body 3 and the main surface of the frame body 3. The locking surface of the 45-degree left lock piece 22 and the side wall surface of the 45-degree oblique cut left side wall 20 are basically located on the same horizontal plane. The locking face of the right lock seat 23 and the side wall of the 45-degree oblique right side wall 21 are basically on the same horizontal plane. When the 45-degree left lock piece 22 corresponds one-to-one with the 45-degree right lock seat 23 on the adjacent frame body and locks, the locking rod of the 45-degree left lock piece 22 locks with the lock hole of the 45-degree right lock seat 23 on the other frame body. At the same time, the locking face of the 45-degree left lock piece 22 and the locking face of the 45-degree right lock seat 23 fit together to form a right angle so as to realize the right angle splicing of the two adjacent LED outdoor displays.

[0038] More specifically, the left and right sides of the frame body 3 are respectively a 45-degree beveled left side wall 20 and a 45-degree beveled right side wall 21. The left and right locking components include a 90-degree left locking component 24 and a 90-degree right locking seat 25. The 90-degree left locking component 24 is provided on the 45-degree beveled left side wall 20, and the 90-degree right locking seat 25 is provided on the 45-degree beveled right side wall 21. The 90-degree left locking component 24 corresponds one-to-one with the 90-degree right locking seat 25 on the adjacent frame body 3 and locks to support the planar splicing of two adjacent LED outdoor display screens.

[0039] In some specific embodiments, replacing the 45-degree lock with a 90-degree lock allows for planar splicing of two adjacent LED outdoor displays. Specifically, the locking surface of the 90-degree left lock 24 is perpendicular to the main surface of the frame body 3, and the locking surface of the 90-degree left lock 24 forms a 45-degree angle with the side wall surface of the 45-degree obliquely cut left side wall 20. The locking surface of the 90-degree right lock seat 25 is perpendicular to the main surface of the frame body 3, and the locking surface of the 90-degree right lock seat 25 forms a 45-degree angle with the side wall surface of the 45-degree obliquely cut right side wall 21. More specifically, the 90-degree lock can be designed such that the mounting surface of the lock piece and the mounting surface of the lock seat are both fitted and fixed to the corresponding 45-degree beveled side wall surface. The lock surface of the lock piece and the lock seat of the 90-degree lock has a 45-degree angle with its respective mounting surface, so that the two lock surfaces have a 45-degree angle with the corresponding side wall surface. That is, the two lock surfaces are set perpendicular to the main surface of the frame body 3. The lock surface of the 90-degree left lock piece 24 and the lock surface of the 90-degree right lock seat 25 face each other and fit together so that the two adjacent LED outdoor display screens can be spliced ​​together.

[0040] Specifically, a HUB board 7 is provided on the side of the frame body 3 facing the drive control box 2. The drive control box 2 includes a control box housing 26, which is detachably fixed to the frame body 3 and covers the HUB board 7. The control box housing 26 includes a power supply 27 and a copper pin socket 28 electrically connected to the power supply 27. The power supply 27 supplies power to the HUB board 7 through the copper pin socket 28. The control box housing 26 also includes a signal test button 29, a signal navigation socket 30, and a signal connector 31. The signal test button 29 and the signal navigation socket 30 are electrically connected to the signal connector 31, which is electrically connected to the HUB board 7 to realize communication signal transmission.

[0041] More specifically, the drive control box 2 also includes a bottom cover, which is a middle frame strip 34 of the frame body 3. The control box housing 26 is fixed to the middle frame strip 34 by a first screw 35. The HUB board 7 is fixed to the middle frame strip 34 by a second screw 36 and a limiting post 37. The HUB board 7 is located between the middle frame strip 34 and the control box housing 26. In fact, it is equivalent to eliminating the bottom shell of the traditional control box and directly replacing the bottom shell of the traditional control box with a middle frame strip 34 on the frame body 3. Therefore, the drive control box 2 of this patent is not a closed box, but a cover-shaped structure that covers the HUB board 7 inside. Replacing the bottom shell of the traditional control box with a middle frame strip 34 of the frame body 3 helps to save costs and improve the compactness of the overall device.

[0042] More specifically, a waterproof sticker 32 is affixed to the bottom inner side of the control box housing 26 to prevent external moisture from entering the control box housing 26, and a waterproof rubber ring 9 is provided on the first electrical interface 8, wherein the waterproof component is waterproof adhesive.

[0043] In summary, this lightweight and waterproof LED outdoor display screen features a hollow frame (3) and a hollow LED display module (1). The weight is significantly reduced through this four-tiered hollow structure: hollow frame, hollow mask (4), hollow light panel (5), and hollow bottom shell (6), saving on transportation and installation costs. Furthermore, this lightweight and waterproof LED outdoor display screen utilizes a vacuum nano-waterproof membrane covering the light panel surface, waterproof gaskets (9), and waterproof adhesive sealing of electrical interfaces. Waterproof stickers (32) are affixed to the control box housing (26) to prevent moisture intrusion, providing multi-faceted waterproof protection. This makes the LED outdoor display screen particularly suitable for rainy or humid outdoor environments. Additionally, this lightweight and waterproof LED outdoor display screen can achieve right-angle or planar connections between adjacent LED displays via a 45-degree beveled wall with 45-degree or 90-degree locking mechanisms.

[0044] It should be noted that this utility model is not limited to the above-described embodiments. Based on the inventive spirit of this utility model, those skilled in the art can make other changes, and these changes made based on the inventive spirit of this utility model should be included within the scope of protection claimed by this utility model.
