[0022] The beneficial effects of the technical solution provided in this application include:

[0023] This application provides a pressure-resistant support mechanism for large-size screens with flexible pressure around the edges. The pressure-resistant support mechanism includes a screen base, which comprises a screen tray for placing the screen, a lower flexible pad for flexibly supporting the screen's perimeter on the top surface of the screen tray, a screen pressure plate located on top of the screen tray, an upper flexible pad for flexibly pressing the screen's perimeter on the bottom surface of the screen pressure plate, and a clamping mechanism fixed to the screen base. The clamping mechanism presses the screen firmly onto the screen tray by pressing down on the screen pressure plate.

[0024] Therefore, the anti-pressure damage support mechanism of this application has a lower flexible pad on the top surface of the screen tray to flexibly support the screen around its perimeter, and an upper flexible pad on the bottom surface of the screen pressure plate to flexibly press the screen around its perimeter. The screen is clamped between the screen tray and the screen pressure plate. When the clamping mechanism presses the screen pressure plate down to press the screen firmly onto the screen tray, both the lower and upper flexible pads undergo a certain amount of compression deformation under external force. While compressing and deforming, the lower and upper flexible pads exert pressure on the screen, effectively preventing the screen from being damaged while clamping and fixing it.

[0025] The anti-pressure damage support mechanism of this application has spring seats fixed at both ends of the screen pressure plate, and a spring block on the top of the spring seats. An elastic element supporting the spring block is provided on the spring seat. The clamping mechanism presses down on the spring block to cause the elastic element to deform elastically, thereby pressing down on the screen pressure plate. When the clamping mechanism presses down on the spring block, the elastic element undergoes compression deformation, pressing down on the spring seat. The screen pressure plate, through the spring seat, presses the screen firmly against the screen support plate. Under external force, the elastic element undergoes a certain amount of compression deformation. While compressing and deforming, the elastic element exerts pressure on the screen, further preventing the screen from being damaged while clamping and fixing it.

[0026] The anti-pressure damage support mechanism of this application has multiple limiting blocks around the top perimeter of the screen tray. These limiting blocks protrude from the top surface of the screen tray, and each limiting block has a shim at its bottom to adjust the height difference between the limiting block and the screen tray. The limiting blocks protrude from the top surface of the screen tray to prevent the screen pressure plate from excessively pressing down on the screen, which could damage it. When the screen pressure plate is pressed down to its lowest set position, the limiting blocks on the screen tray abut against the pressure plate to prevent further pressure and ensure screen safety. The shims at the bottom of the limiting blocks facilitate height adjustment to meet the needs of screens of different thicknesses.

[0027] The anti-pressure support mechanism of this application has multiple screen positioning pins around the top perimeter of the screen tray, surrounding the screen. Both the lower and upper flexible pads have through holes for the screen positioning pins to pass through, and the bottom surface of the screen pressure plate has positioning holes that mate with the screen positioning pins. The screen positioning pins around the top perimeter of the screen tray provide positioning for the screen, which is positioned within the space enclosed by the multiple screen positioning pins. These pins also provide precise positioning for the lower flexible pad, preventing movement of the screen and the lower flexible pad on the screen tray and improving reliability during pressure testing.

[0036] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0037] This application provides a flexible pressure-resistant support mechanism for the perimeter of a large screen, which solves the problem in related technologies where the pressure applied to the perimeter of the screen is difficult to control, posing a risk of damaging the screen and causing economic losses.

[0038] See Figure 1 and Figure 2 As shown, this application embodiment provides a pressure-resistant support mechanism for flexible pressing around a large screen, including:

[0039] The screen base 1 includes a screen support plate 11 for horizontally placing the screen 4, and a lower flexible pad 7 for flexibly supporting the screen 4 around its perimeter on the top surface of the screen support plate 11. The screen support plate 11 is a rectangular plate of a set thickness to support the rectangular structure of the screen 4, and the lower flexible pad 7 is a rectangular structure adapted to the screen 4, with the bottom perimeter of the screen 4 located on top of the lower flexible pad 7.

[0040] The screen pressure plate 2 is located on top of the screen support plate 11 and is parallel to the screen support plate 11. The bottom surface of the screen pressure plate 2 is provided with upper flexible pads 6 that flexibly press against the perimeter of the screen 4. The screen pressure plate 2 is a rectangular plate of a set thickness to press against the rectangular structure of the screen 4. The upper flexible pads 6 are rectangular structures adapted to the screen 4. The top perimeter of the screen 4 is located at the bottom of the lower flexible pads 7.

[0041] Two clamping mechanisms 3 are provided, fixed at both ends of the screen base 1. These two clamping mechanisms 3 simultaneously press down on the screen pressure plate 2 to press the screen 4 firmly onto the screen support plate 11, preventing the screen 4 from shifting during the process of creating ripples. When the screen pressure plate 2 presses the screen 4 firmly onto the screen support plate 11, the upper flexible pad 6 and lower flexible pad 7 located on the top and bottom surfaces of the screen 4 have compression deformation capabilities and are in flexible contact with the screen 4, preventing excessive pressure from the clamping mechanisms 3 from damaging the screen 4.

[0042] The anti-pressure damage support mechanism of this embodiment has a lower flexible pad 7 on the top surface of the screen support plate 11 to flexibly support the screen 4 around its perimeter, and an upper flexible pad 6 on the bottom surface of the screen pressure plate 2 to flexibly press the screen 4 around its perimeter. The screen 4 is clamped between the screen support plate 11 and the screen pressure plate 2. When the clamping mechanism 3 presses down on the screen pressure plate 2 to press the screen 4 firmly onto the screen support plate 11, both the lower flexible pad 7 and the upper flexible pad 6 undergo a certain amount of compression deformation under external force. While compressing and deforming, the lower flexible pad 7 and the upper flexible pad 6 exert pressure on the screen 4, effectively preventing the screen 4 from being damaged while clamping and fixing it.

[0043] In some alternative embodiments: see Figures 3 to 5 As shown in the embodiment of this application, a pressure-resistant support mechanism for a large-size screen with flexible pressing around its perimeter is provided. The screen pressure plate 2 of this pressure-resistant support mechanism has a light-transmitting hole that exposes the screen 4. This light-transmitting hole facilitates the use of a probe to apply pressure to the display area of ​​the screen 4 when creating ripples on the front of the screen 4. Spring seats 21 are fixedly installed at the bottom of both ends of the screen pressure plate 2, and spring blocks 22 are installed at the top of the spring seats 21. Elastic members 23 that elastically support the spring blocks 22 are provided on the spring seats 21. The clamping mechanism 3 presses down on the screen pressure plate 2 by pressing down on the spring blocks 22 to cause the elastic members 23 to elastically deform.

[0044] The spring seat 21 includes two vertically arranged columns fixed to the screen pressure plate 2 and spaced apart from each other. A horizontally arranged connecting block connects the two columns, forming a "U" shape with the columns. An elastic element 23 is fixed to the connecting block. The elastic element 23 is preferably, but not limited to, a helical compression spring. Multiple elastic elements 23 are provided and spaced apart along the length of the connecting block. A guide post 24 is vertically provided at the top of the connecting block to slide the spring pressure block 22. A stop is provided at the top of the guide post 24 to prevent the spring pressure block 22 from disengaging from the connecting block. The spring pressure block 22 moves up and down on the connecting block along the axis of the guide post 24. A clearance is provided between the spring pressure block 22 and the connecting block for the expansion and contraction of the elastic element 23.

[0045] The screen base 1 also includes a base 13 located at the bottom of the screen support plate 11, and a base plate 12 fixed to the bottom of the screen support plate 11. The base 13 is provided with a bracket 14 to support the base plate 12 to a set height. The spring seat 21 is fixed to the bottom of the screen pressure plate 2. The base plate 12 has elongated holes at both ends for the spring seat 21 to extend into. The spring seat 21 can move freely up and down within the elongated holes at both ends of the base plate 12.

[0046] The anti-pressure support mechanism of this embodiment has spring seats 21 fixed at both ends of the screen pressure plate 2, and a spring block 22 on the top of the spring seat 21. An elastic element 23 is provided on the spring seat 21 to elastically support the spring block 22. The clamping mechanism 3 presses down on the spring block 22 to cause the elastic element 23 to elastically deform, thereby pressing down on the screen pressure plate 2. When the clamping mechanism 3 presses down on the spring block 22, the elastic element 23 undergoes compression deformation to press down on the spring seat 21, and the screen pressure plate 2 presses the screen 4 tightly onto the screen support plate 11 through the spring seat 21. The elastic element 23 undergoes a certain amount of compression deformation under external force. While compressing and deforming, the elastic element 23 exerts pressure on the screen 4, further preventing the screen 4 from being damaged while clamping and fixing it.

[0047] In some alternative embodiments: see Figure 2 As shown in the figure, this application embodiment provides a pressure-resistant support mechanism for large-size screens with flexible pressing around the perimeter. The screen support plate 11 of this pressure-resistant support mechanism has multiple limiting blocks 16 around its top perimeter, with each limiting block 16 protruding from the top surface of the screen support plate 11. The bottom of each limiting block 16 has a pad (not shown in the figure) for adjusting the height difference between the limiting block 16 and the screen support plate 11. The top surface of the limiting block 16 is higher than the top surface of the screen support plate 11, and the height difference between the top surface of the limiting block 16 and the top surface of the screen support plate 11 is greater than or equal to the thickness of the screen 4 being tested. When the top surface of the limiting block 16 contacts the bottom surface of the screen pressure plate 2, the limiting block 16 prevents the screen pressure plate 2 from continuing to press down on the screen 4.

[0048] The anti-pressure support mechanism of this embodiment has multiple limiting blocks 16 around the top perimeter of the screen support 11. Each limiting block 16 protrudes from the top surface of the screen support 11, and a shim is provided at the bottom of each limiting block 16 to adjust the height difference between the limiting block 16 and the screen support 11. The limiting blocks 16 protrude from the top surface of the screen support 11 to prevent the screen pressure plate 2 from excessively pressing down on the screen 4, which could damage the screen 4. When the screen pressure plate 2 is pressed down to the lowest set position, the limiting blocks 16 on the screen support 11 abut against the screen pressure plate 2 to prevent the screen pressure plate 2 from continuing to press down on the screen 4, ensuring the safety of the screen 4. The shims at the bottom of the limiting blocks 16 facilitate adjustment of the height of the limiting blocks 16 to meet the needs of screens of different thicknesses.

[0049] In some alternative embodiments: see Figure 2 As shown, this application embodiment provides a pressure-resistant support mechanism for the flexible pressing around the perimeter of a large-size screen, the screen of which is designed to prevent pressure damage.

[0050] Multiple screen positioning pins 15 are provided around the top perimeter of the screen 4. The lower flexible pad 7 and the upper flexible pad 6 each have through holes for the screen positioning pins 15 to pass through. The bottom surface of the screen pressure plate 2 has positioning holes that match the screen positioning pins 15. The screen positioning pins 15 surrounding the screen 4 facilitate quick positioning of the screen 4 on the top of the screen support 11. The screen positioning pins 15 also provide positioning for the lower flexible pad 7, ensuring the positional accuracy of the screen 4 and the lower flexible pad 7 on the screen support 11.

[0051] The anti-pressure support mechanism of this application has multiple screen positioning pins 15 around the top perimeter of the screen tray, which surround the screen 4; both the lower flexible pad 7 and the upper flexible pad 6 have through holes for inserting the screen positioning pins 15, and the bottom surface of the screen pressure plate 2 has positioning holes that match the screen positioning pins 15.

[0052] Positioning pin 15 provides positioning for screen 4, which is positioned within the space 5 enclosed by multiple screen positioning pins 15. The screen positioning pins 15 also provide precise positioning for the lower flexible pad 7, preventing screen 4 and the lower flexible pad 7 from moving on the screen support plate 11 and improving reliability during the press test.

[0053] In some alternative embodiments: see Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown in the figure, this application embodiment provides a pressure-resistant support mechanism for flexible pressing around a large screen to prevent pressure damage.

[0054] The clamping mechanism 3 of the pressure support mechanism is a quick clamp, which is fixed to the bracket 14 of the screen base 10. The clamping head presses down on the spring block 22 at the bottom of the screen pressure plate 2. The spring block 22 presses down on the elastic element 23. While the elastic element 23 is compressed and deformed, it presses down on the spring seat 21. The spring seat 21 drives the screen pressure plate 2 to press down on the screen 4. The lower flexible pad 7 and the upper flexible pad 6 are any one of plastic pads, rubber pads, or sponge pads.

[0055] The pads are all made of flexible materials with elastic deformation capabilities to prevent the screen pressure plate 2 from pressing down on the screen 5 and screen 4 excessively, causing damage to the screen 4.

[0056] Handles 25 for picking up and placing the screen pressure plate 2 are provided on both sides of the screen pressure plate 2. The handles 25 are used to facilitate picking up and placing the screen pressure plate 2. A circuit board 5 for lighting up the screen 4 is provided on one side of the screen support plate 11. A ribbon cable (not shown in the figure) extending into the screen support plate 11 and connecting to the screen 4 is connected to the circuit board 5. When creating ripples on the front of the screen 4, the circuit board 5 is used to light up the screen 4 through the ribbon cable. Guide pins 17 are vertically provided at opposite corners of the screen support plate 11. Guide holes that match the guide pins 17 are opened at opposite corners of the screen pressure plate 2. The top of the guide pin 17 is conical or spherical. The guide pins 17 are used to accurately position the screen pressure plate 2 and the screen support plate 11.
