Abstract
Description
Technical Field
[0001] This utility model relates to the field of display device technology, and in particular to a grandstand screen. Background Technology
[0002] LED grandstand screens are LED screens installed in stadium grandstands, mainly used for information display, advertising, and special effects video playback within the stadium. They feature high brightness and high definition, wide viewing angle, vibrant and rich colors, fast response, and high reliability, playing a significant role in on-site information display and atmosphere creation. In recent years, the application of LED grandstand screens in various sports venues has become increasingly widespread.
[0003] Because LED grandstand screens are installed on stadium stands, traditional front and rear maintenance methods are inconvenient in daily use. Therefore, many displays that can be maintained from the top have emerged in the industry, allowing damaged parts to be removed and repaired directly from the top of the screen on the stands.
[0004] Currently, LED displays that can be maintained from the top have hanging nails at the four corners of the LED cabinet and positioning holes at the bottom; the mounting bracket has a sliding groove on the vertical beam and a positioning post at the bottom. During installation, the bracket is first fixed to the mounting base, then the LED cabinet is lifted and flipped over the grandstand. The hanging nails at the four corners are then lowered from top to bottom along the sliding groove of the bracket's vertical beam until the bottom of the cabinet contacts the bracket's support plate, completing the cabinet installation.
[0005] To ensure the flatness of the cabinet after installation, the positional precision of the hooks at the four corners of the cabinet, the dimensional accuracy of the sliding grooves of the bracket, and the spacing precision of the two vertical beams on the bracket all require high precision, resulting in a high overall cost for the grandstand screen. Furthermore, even slight deviations in dimensions can lead to uneven sliding or jamming during installation, resulting in a poor user experience. In addition, existing grandstand screens require the cabinet to be raised during installation, and to avoid collisions with adjacent cabinets, the cabinet must be carefully lowered vertically, a time-consuming and labor-intensive process that makes assembly quite difficult.

[0038] See Figure 1 , Figure 2 as well as Figure 4 One embodiment of this application provides a grandstand screen 100, which is typically used for displaying images in outdoor environments. The grandstand screen 100 includes a mounting bracket 10 and a housing 20.
[0039] The mounting bracket 10 includes a bracket body 11, a locking member 12 disposed on the top of the bracket body 11, and at least two positioning parts 13 disposed near the bottom of the bracket body 11. The bracket body 11 is used to fix to the external mounting surface 200, and the positioning parts 13 are disposed on the side of the bracket body 11 opposite to the external mounting surface 200.
[0040] The housing 20 includes a frame 21 and a display module 22 mounted on the frame 21. The display module 22 is used for image display. The housing 20 also includes fasteners 23 mounted on the top of the frame 21 and at least two mating portions 24 located near the bottom of the frame 21. The mating portions 24 are located on the side of the frame 21 opposite to the display module 22. The multiple mating portions 24 can be positioned and mated with multiple positioning portions 13 in a one-to-one correspondence. The fasteners 23 can be engaged and fixed with locking members 12, so that the housing 20 is positioned and fixed on the mounting bracket 10.
[0041] For the grandstand screen 100 of this application, the locking member 12 on the bracket body 11 can be engaged and fixed with the fastener 23 on the frame 21. Furthermore, at least two positioning parts 13 on the bracket body 11 can be positioned and docked one-to-one with at least two docking parts 24 on the frame 21, enabling the housing 20 to be positioned and locked on the mounting bracket 10 at least by three points. Through the engagement of the locking member 12 with the fastener 23 and the positioning docking of the positioning parts 13 with the docking parts 24, not only can the housing 20 be positioned and fixed on the mounting bracket 10, but the overall structure of the housing 20 and the mounting bracket 10 can also be simplified, reducing the machining precision requirements for both, enabling rapid installation and locking of the housing 20 and the mounting bracket 10, and improving the installation efficiency of the grandstand screen 100.
[0042] In some embodiments of this application, such as Figure 2 and Figure 3 As shown, the mounting bracket 10 includes a bracket body 11, a locking member 12 disposed on the top of the bracket body 11, and at least two positioning parts 13 disposed near the bottom of the bracket body 11.
[0043] The main body 11 of the mounting bracket is a rectangular frame structure, comprising a pair of opposing horizontal beams 111 and two vertical beams 112 connecting the two horizontal beams 111. The two horizontal beams 111 and the two vertical beams 112 are joined to form a rectangular mounting bracket 10. Corner blocks 115 can be installed at the connection between the horizontal beams 111 and the vertical beams 112 to enhance the overall structural strength of the mounting bracket 10.
[0044] The crossbeam 111 has mounting holes 113, through which an accessory can pass to fix the mounting bracket 10 to the external mounting surface 200. The accessory can be an expansion bolt. Mounting holes 113 are provided at both ends of the crossbeam 111 along its length, and the mounting holes 113 are located near the connection between the crossbeam 111 and the vertical beam 112.
[0045] In this embodiment, the locking member 12 is disposed on the top crossbeam 111, and the locking member 12 is arranged near the center of the crossbeam 111. The locking member 12 is a hook structure, which can be fixed to the top surface of the crossbeam 111 by screws, or it can be integrally formed with the crossbeam 111.
[0046] In some examples, the mounting bracket 10 may include two positioning parts 13. Both positioning parts 13 are disposed on the bottom crossbeam 111, and are located near both ends of the crossbeam 111. In this example, the two positioning parts 13 are respectively arranged on both sides of the locking member 12, and the line connecting the positions of the two positioning parts 13 on the bracket body 11 and the position of the locking member 12 on the bracket body 11 approximates an isosceles triangle, forming a three-point mating position.
[0047] In some embodiments of this application, the mounting bracket 10 may further include a support plate 114, which protrudes from the surface of the bracket body 11, and a positioning part 13 is disposed on the support plate 114. The support plates 114 and the positioning parts 13 may have a one-to-one correspondence, meaning the number of support plates 114 is the same as the number of positioning parts 13. It should be noted that multiple positioning parts 13 may also be provided on a single support plate 114.
[0048] In this embodiment, the support plate 114 protrudes from the surface of the crossbeam 111. Support plates 114 are provided at both ends of the bottom crossbeam 111, and positioning portions 13 are provided on the support plates 114. In some examples, the positioning portion 13 can be a columnar structure protruding from the surface of the support plate 114, and the mating portion 24 on the frame 21 is a hole-like structure adapted to the columnar structure. In some examples, the positioning portion 13 can be a hole-like structure formed in the support plate 114, and the mating portion 24 on the frame 21 is a columnar structure adapted to the hole-like structure.
[0049] In addition, such as Figure 2 As shown, the mounting bracket 10 may also include a connecting piece 116. The connecting piece 116 is disposed on the side wall of the end of the bottom crossbeam 111, and the connecting piece 116 is provided with a positioning post 117 or a positioning hole. The positioning post 117 protrudes from the surface of the connecting piece 116. When two adjacent mounting brackets 10 are mated, the connecting piece 116 on the side wall of the vertical beam 112 can achieve positioning and fixation of multiple mounting brackets 10 on the flat external mounting surface 200 through the mating of the positioning post 117 and the positioning hole.
[0050] In some examples, the connecting piece 116 is detachably connected to the bracket body 11 by screws. When the mounting bracket 10 is fixed on the arc-shaped outer mounting surface 200, the connecting piece 116 needs to be removed from the bracket body 11 first, and then the multiple mounting brackets 10 are positioned and fixed on the arc-shaped outer mounting surface.
[0051] like Figure 4 and Figure 5 As shown, the housing 20 includes a frame 21 and a display module 22 disposed on the frame 21. The display module 22 is used for image display. The housing 20 also includes a fastener 23 disposed on the top of the frame 21 and at least two mating portions 24 disposed near the bottom of the frame 21. The mating portions 24 are disposed on the side of the frame 21 opposite to the display module 22.
[0052] In some embodiments of this application, the frame 21 is a rectangular structure, and a display module 22 and a power module 25 are respectively mounted on opposite side surfaces of the frame 21. The power module 25 is arranged near the center of the frame 21 and is used to supply power to the display module 22.
[0053] The top of the frame 21 is provided with a handle hole 26, which is used for hand gripping to facilitate lifting of the housing 20. The frame 21 is provided with handles 27 at intervals on the side opposite to the display module 22. The handles 27 can be arranged on both sides of the power module 25, and are used for hand gripping to realize the carrying of the housing 20.
[0054] In this embodiment, the fastener 23 is positioned near the centerline of the frame 21, and the housing 20 may include two mating portions 24, which are respectively arranged on both sides of the fastener 23. In this example, the two mating portions 24 are respectively arranged on both sides of the fastener 23, and the line connecting the positions of the two mating portions 24 on the frame 21 and the positions of the fastener 23 on the frame 21 is approximately an isosceles triangle, thus forming a three-point mating position.
[0055] In some embodiments of this application, the housing 20 may further include an extension plate 28, which protrudes from the surface of the frame 21 opposite to the display module 22, and a mating portion 24 is disposed on the extension plate 28. The extension plates 28 may correspond one-to-one with the mating portions 24, meaning the number of extension plates 28 is the same as the number of mating portions 24. It should be noted that multiple mating portions 24 may also be provided on a single extension plate 28.
[0056] In this embodiment, the extension plate 28 protrudes from the surface of the frame 21, and extension plates 28 are provided on both sides near the bottom of the frame 21. The extension plates 28 have mating portions 24. In some examples, the mating portion 24 is a hole-like structure formed in the extension plate 28, and the positioning portion 13 of the mounting bracket 10 is a columnar structure protruding from the surface of the tray 114, capable of positioning and mating with the hole-like mating portion 24. In some examples, the mating portion 24 is a columnar structure protruding from the extension plate 28, and the positioning portion 13 of the mounting bracket 10 is a hole-like structure formed in the tray 114, capable of positioning and mating with the columnar structure's mating portion 24.
[0057] Combination Figure 6 As shown, in some embodiments of this application, the locking member 12 on the mounting frame 21 is a hook structure. The fastener 23 disposed on the frame 21 may include a fastening body 231 and a snap-fit ring 232 disposed on the fastening body 231. The snap-fit ring 232 is rotatably disposed on the fastening body 231 and can be hooked onto the locking member 12 to snap and fix it to the locking member 12.
[0058] The fastening body 231 includes a base portion 2311 and a latch portion 2312. The base portion 2311 is mounted on the frame 21. The latch portion 2312 is rotatably mounted on the base portion 2311, and a snap-fit ring 232 is rotatably mounted on the latch portion 2312. The snap-fit ring 232 is engaged with the locking member 12. The latch portion 2312 rotates relative to the base portion 2311 in a direction away from the locking member 12. The latch portion 2312 can pull the snap-fit ring 232 in a direction away from the locking member 12, so that the snap-fit ring 232 is hooked onto the locking member 12, thereby effectively locking the snap-fit ring 232 onto the locking member 12.
[0059] In some embodiments of this application, such as Figure 2 , Figure 4 as well as Figure 6 , Figure 7 As shown, the grandstand screen 100 also includes a pre-locking component 30, which includes a lock body 31 disposed on the main body 11 of the bracket and a ball catch 32 disposed on the frame 21.
[0060] The lock body 31 is provided with a pre-locking groove 311, and the end of the ball catcher 32 can be detachably snapped into the pre-locking groove 311. By snapping the ball catcher 32 into the pre-locking groove 311, the box 20 and the mounting bracket 10 can be pre-locked, and the top area of the box 20 can be positioned on the mounting bracket 10.
[0061] In some examples, the lock body 31 is arranged on the top of the bracket body 11 and corresponds to the locking member 12. The lock body 31 includes a lock seat portion 312 fixed to the bracket body 11 and a pair of ball portions 313 disposed opposite to each other on the lock seat portion 312. Both ball portions 313 can elastically move relative to the lock seat portion 312 to move closer or further away from each other, and a pre-locking groove 311 is formed between the two ball portions 313.
[0062] In this example, the ball catcher 32 is positioned at the top of the frame 21 and below the fastener 23. The two ends of the ball catcher 32 are a large end 321 and a small end 322, with the small end 322 fixed to the frame 21. The large end 321 and the small end 322 form an arc transition, creating arc-shaped abutment surfaces 323 on both sides of the ball catcher 32.
[0063] When the catch ball 32 is engaged with the lock body 31, when the large end 321 of the catch ball 32 is engaged in the pre-locking groove 311, the large end 321 can push the two ball parts 313 away from each other, so that the catch ball 32 is engaged in the pre-locking groove 311 and the two ball parts 313 respectively abut against the abutment surfaces 323 on both sides of the catch ball 32, thereby achieving the locking of the catch ball 32 and the lock body 31.
[0064] In addition, such as Figure 8As shown, the housing 20 may also include a top cover 29, which is detachably connected to the top of the frame 21 and the display module 22. The top cover 29 can be screwed onto the frame 21, snapped onto the frame 21, or connected to the frame 21 by an interference fit.
[0065] The top cover 29 serves to aesthetically pleasingly and conceal the internal wiring of the housing 20. The top of the top cover 29 is designed with a slope to prevent visitors from placing items on it. The top of the top cover 29 may have a cover hole 291, which allows a person to hold the top cover 29 for carrying, disassembling and moving the top cover 29.
[0066] like Figures 9 to 12 As shown, when the grandstand screen 100 of this application is installed on the external mounting surface 200 of the external grandstand, the mounting bracket 10 is first fixed to the outside of the external grandstand, while the cabinet 20 and the workers are on the inside of the external grandstand.
[0067] After the mounting bracket 10 is fixed in place, the worker can hold the handle 27 on the container 20 to lift the container 20 and lower it over the outer platform. During the lowering process, the container 20 is some distance away from the adjacent container 20, so there is no need to worry about collisions, and it can be lowered quickly.
[0068] When the docking part 24 of the housing 20 approaches the support plate 114 of the mounting bracket 10, the housing 20 is tilted so that the docking part 24 on the extension plate 28 is inserted into the positioning part 13 on the support plate 114 of the mounting bracket 10. The support plate 114 and the positioning part 13 of the mounting bracket 10 are used to support and position the housing 20.
[0069] Then move the housing 20 toward the mounting bracket 10 so that the ball catcher 32 can be locked in the pre-locking groove 311 of the lock body 31, thereby achieving pre-locking of the housing 20 and the mounting bracket 10, and simultaneously positioning the top of the housing 20 in the left and right directions.
[0070] Next, the snap ring 232 is snapped onto the locking member 12, and the latch portion 2312 is rotated relative to the base portion 2311 in a direction away from the locking member 12, so that the snap ring 232 is locked onto the locking member 12, thereby locking the housing 20 and the mounting bracket 10. Finally, the connecting wires of the housing 20 are connected, and the top cover 29 is installed on the top of the housing 20 to complete the assembly of the grandstand screen 100 on the external grandstand.
[0071] For the grandstand screen of this application, the locking components on the main body of the mounting bracket can be engaged and fixed with the fasteners on the frame. Furthermore, at least two positioning parts on the main body of the mounting bracket can be positioned and engaged one-to-one with at least two mating parts on the frame, allowing the enclosure to be positioned and locked on the mounting bracket at least by three points. Through the engagement of the locking components with the fasteners and the positioning and engagement of the positioning parts with the mating parts, not only can the enclosure be positioned and fixed on the mounting bracket, but the overall structure of the enclosure and the mounting bracket can also be simplified, reducing the precision requirements for both, enabling rapid installation and locking of the enclosure and the mounting bracket, and improving the installation efficiency of the grandstand screen.
