DETAILED DESCRIPTION

[0029] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0030] The folding durability testing device of the flexible foldable touch screen according to the embodiment of the present application is described below with reference to the accompanying drawings.

[0031] like Figure 1 and Figure 2 As shown, the folding durability testing device of the flexible foldable touch screen of the embodiment of the present application may include an operating table 100, a longitudinal micro-motion structure 200, a clamping device 300, a transverse micro-motion structure 400, a flipping device 500 and an adsorption device 600.

[0032] The longitudinal micro-motion structure 200 is embedded on the operating table 100 and can achieve slight movement along the longitudinal direction.

[0033] The clamping device 300 is movably disposed on the operating table 100 and is located above the longitudinal micro-motion structure 200 , wherein the clamping device 300 is used to clamp the fixed end of the flexible screen 700 .

[0034] It should be noted that when the clamping device 300 moves to the top of the longitudinal micro-motion structure 200 , it can press down the longitudinal micro-motion structure 200 to cause it to deform slightly.

[0035] The transverse micro-motion structure 400 is disposed on the operating platform 100 and connected to the clamping device 300 .

[0036] It should be noted that the transverse micro-motion structure 400 can pull the clamping device 300 to reset when the clamping device 300 moves slightly, so that the clamping device 300 is reset to just above the longitudinal micro-motion structure 200 .

[0037] The adsorption device 600 can be movably arranged at the flipping end of the flipping device 500, and the center of the rotating axis 510 of the flipping device 500 is coaxially arranged with the flipping axis of the flexible screen 700; wherein, the adsorption device 600 is used to adsorb the back side of the flipping end of the flexible screen 700.

[0038] It should be noted that the turning device 500 can be disposed on the operating table 100 , and the turning device 500 can realize reciprocating turning.

[0039] In addition, the flipping device 500 is externally connected to a controller, and the controller has a built-in counting module for recording the flipping times of the flipping device 500 .

[0040] Specifically, when the relevant staff conducts a durability test on the flexible screen 700 , first, the relevant staff clamps the fixed end of the flexible screen 700 on the clamping device 300 , and then adsorbs the adsorption device 600 on the back side of the flip end of the flexible screen 700 .

[0041] Next, the relevant staff starts the flipping device 500, so that the flipping end of the flipping device 500 drives the flipping ends of the adsorption device 600 and the flexible screen 700 to perform a flipping operation.

[0042] When the flipping device 500 drives the flipping end cover of the flexible screen 700 to close on the fixed end of the flexible screen 700, the flipping device 500 can continue to rotate at a small angle (for example, 1 degree or 2 degrees, not specifically limited here), so that the flexible screen 700 presses down the longitudinal micro-motion structure 200. The longitudinal micro-motion structure 200 is squeezed and slightly deformed, and vibrates, causing the clamping device 300 and the flexible screen 700 to vibrate slightly, thereby simulating the vibration that occurs when people actually open and close the flexible screen 700.

[0043] Next, the flipping device 500 drives the adsorption device 600 and the flipping end of the flexible screen 700 to reverse. At this time, due to the flipping damping of the flexible screen 700 itself, when the flipping end and the fixed end of the flexible screen 700 are opened, the flipping end of the flexible screen 700 can drive the fixed end to move slightly. At this time, the lateral micro-motion structure 400 is deformed, causing the lateral micro-motion structure 400 to vibrate slightly, and the clamping device 300 and the flexible screen 700 follow with slight vibrations, thereby simulating the vibration that occurs when people actually open and close the flexible screen 700.

[0044] When the flip end of the flexible screen 700 is covered on the fixed end again, vibration still occurs during the resetting process of the lateral micro-motion structure 400. The continuous slight vibration can more realistically simulate the vibration people experience during actual use.

[0045] In addition, since people actually use the flexible screen 700 (such as a folding mobile phone, etc.), they often need to open and close the flexible screen 700 with one hand. Under normal circumstances, the one-handed operation method is to hold the flexible screen 700 with the palm of the hand, and lift the flip end of the flexible screen 700 with the thumb to open and close it. In this case, since the position where the thumb lifts the flexible screen 700 is biased to one side, the flip end of the flexible screen 700 is unevenly stressed (that is, the side close to the thumb is subjected to greater stress).

[0046] When conducting a simulation test on the above-mentioned behavior, relevant staff may move the position of the adsorption device 600 on the flip device 500 so that the adsorption device 600 is close to one side of the flexible screen 700 and adsorbed on the back of the corresponding side.

[0047] In one embodiment of the present application, Figure 3 As shown, the longitudinal micro-motion structure 200 includes a movable plate 210 , a bracket 220 and a first spring 230 .

[0048] The operating table 100 is provided with a slot 101 , the movable plate 210 is embedded in the slot 101 , the bracket 220 is arranged below the operating table 100 , and two ends of the first spring 230 are respectively connected to the bracket 220 and the movable plate 210 .

[0049] The movable plate 210 is provided with a vertically upward limiting column 211 , and the clamping device 300 is connected to the limiting column 211 in a lateral sliding manner.

[0050] It should be noted that the size of the slot 101 is larger than the size of the clamping device 300. Therefore, when the flipping device 500 drives the adsorption device 600 and the flexible screen 700 to continue to press down, the clamping device 300 can press down the longitudinal micro-motion structure 200, thereby avoiding the situation where the clamping device 300 is limited by the operating table 100 and cannot press down the longitudinal micro-motion structure 200.

[0051] Specifically, when the flipping device 500 drives the flipping end cover of the flexible screen 700 to close on the fixed end, the entire clamping device 300 presses down the longitudinal micro-motion structure 200, that is, the clamping device 300 presses down the movable plate 210, so that the first spring 230 is compressed and deformed. At this time, the longitudinal micro-motion structure 200 is slightly deformed, which can cause slight vibration to the clamping device 300 and the flexible screen 700.

[0052] In one embodiment of the present application, Figure 4 and Figure 5 As shown, the clamping device 300 includes a placement plate 310 and a stop plate 320 .

[0053] Among them, the two abutment plates 320 are detachably arranged on the placement plate 310 to respectively abut against the two sides of the fixed end of the flexible screen 700.

[0054] As a possible situation, slide grooves 311 are respectively opened on both sides of the placement plate 310, and a slider 321 is provided at the bottom of the abutment plate 320. The slider 321 is slidably connected to the slide groove 311 and is locked by bolts.

[0055] It should be noted that by sliding to adjust the positions of the two abutment plates 320 , the two abutment plates 320 can be adapted to the flexible screens 700 of different widths, thereby improving their adaptability.

[0056] As a possible situation, a limiting groove 312 is opened in the horizontal direction on the placement plate 310 , and the limiting column 211 passes through the limiting groove 312 and extends upward in the longitudinal direction.

[0057] It should be noted that a limiting head may be provided on the top of the limiting column 211 .

[0058] In one embodiment of the present application, Figure 4 As shown, the transverse micro-motion structure 400 includes a connecting plate 410 and a second spring 420 .

[0059] The connecting plate 410 is fixed on the operating table 100 , and two ends of the second spring 420 are respectively connected to the connecting plate 410 and the clamping device 300 .

[0060] It should be noted that when the flipping device 500 drives the flexible screen 700 to cover, the clamping device 300 can achieve a slight downward pressure on the longitudinal micro-motion structure 200. At this time, the second spring 420 is completely twisted due to the downward movement of the clamping device 300, and when the flipping device 500 drives the flexible screen 700 to open, the clamping device 300 is reset, so that the bending of the second spring 420 can be reset, and with the slight movement of the clamping device 300, the second spring 420 can be pulled to deform, so that the second spring 420 is in continuous vibration.

[0061] In one embodiment of the present application, Figure 6 As shown, the turning device 500 includes a rotating shaft 510 , a rotating plate 520 , a driving motor 530 and a support 540 .

[0062] Among them, the rotating shaft 510 is arranged on a side away from the fixed end of the flexible screen 700, the two rotating plates 520 are respectively connected to the two ends of the rotating shaft 510, the driving motor 530 and the support 540 are respectively arranged opposite to each other on the operating table 100, the output end of the driving motor 530 is connected to one of the rotating plates 520, and the support 540 is axially connected to the other rotating plate 520.

[0063] It should be noted that the output end of the driving motor 530, the shaft connection end of the support 540 and the flip axis of the flexible screen 700 are located on the same axis.

[0064] Specifically, when the relevant staff turns on the driving motor 530, the rotation of the driving motor 530 drives the rotation of the rotating plate 520, thereby causing the rotating shaft 510 to rotate, and the adsorption device 600 on the rotating shaft 510 can adsorb the flipping end of the flexible screen 700 and realize flipping.

[0065] It should be noted that the reciprocating reversal of the reversing device 500 can be achieved by controlling the forward and reverse rotation of the driving motor 530 .

[0066] In one embodiment of the present application, Figure 6 and Figure 7 As shown, the adsorption device 600 includes a suction cup 610 , a connecting member 620 and an extension rod 630 .

[0067] The extension rod 630 is slidably disposed on the rotating shaft 510 and is locked by bolts, the connecting member 620 is disposed on the extension rod 630 , and the suction cup 610 is movably disposed on the connecting member 620 and is locked by a damping knob 621 .

[0068] As a possible situation, a compensation groove 622 is formed on the connecting member 620 , and the damping knob 621 slides along the compensation groove 622 .

[0069] It should be noted that when the flipping device 500 drives the flexible screen 700 to open, due to the flipping damping of the flexible screen 700, it can drive the clamping device 300 to slightly shift in the lateral direction. At this time, the center of the rotating axis 510 of the flipping device 500 and the flipping axis of the flexible screen 700 are not coaxial, and compensation is performed through the compensation groove 622 on the connecting piece 620, so that the damping knob 621 slides slightly along the compensation groove 622.

[0070] To clearly illustrate the previous embodiment, in one embodiment of the present application, the rotating shaft 510 is provided with a groove 511 along the length direction, the end of the extension rod 630 is slidably sleeved on the rotating shaft 510, and the locking bolt passes through the end of the extension rod 630 and abuts against the groove 511.

[0071] It should be noted that when relevant staff conduct durability tests on different sides of the flexible screen 700, they can loosen the locking bolt and then push the extension rod 630. The extension rod 630 will slide on the rotating shaft 510 until the suction cup 610 reaches a suitable position, and then re-tighten the locking bolt.

[0072] In summary, the folding durability testing device of the flexible foldable touch screen in the embodiment of the present application can simulate the one-handed operation of people during daily use by adjusting the position of the adsorption device, so as to test the influence of uneven force on the durability of the flexible screen when opened and closed with one hand. In addition, by setting the longitudinal micro-motion structure and the transverse micro-motion structure, the vibration generated by people when opening and closing the flexible screen is simulated, so that the test data is more accurate.
