[0039] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0040] See also Figures 1 to 3 An embodiment of the present application provides an arc adjustment mechanism 100 that can achieve arc adjustment of a flexible module 200 in a display screen. The arc adjustment mechanism 100 includes an adjustment body 10, a connecting arm 20, an adjustment arm 30, and a driving assembly 40.

[0041] Specifically, the connecting arm 20 is fixed to the adjusting body 10. The connecting arm 20 is used to connect to a partial area on the surface of the flexible module 200. The adjusting arm 30 is movably arranged on the adjusting body 10. The adjusting arm 30 is used to connect to another partial area on the surface of the flexible module 200. The adjusting arm 30 moves relative to the adjusting body 10, and the adjusting arm 30 can move relatively closer to or farther away from the connecting arm 20, so that the flexible module 200 assumes a convex or concave arc shape. The driving assembly 40 includes a handle member 41 arranged on the adjusting body 10 and a linkage member 42 connected to the handle member 41. The linkage member 42 is connected to the adjusting arm 30. The handle member 41 can move and rotate relative to the adjusting body 10.

[0042] Among them, when the handle member 41 moves relative to the adjusting body 10, it has a first position (as Figure 2 shown) and a second position (as Figure 1 shown). When the handle member 41 moves to the first position, the handle member 41 can rotate relative to the adjusting body 10 to drive the linkage member 42 to rotate, so that the adjusting arm 30 moves relative to the adjusting body 10, so that the adjusting arm 30 can move relatively closer to or farther away from the connecting arm 20. When the handle member 41 moves to the second position, the handle member 41 and the linkage member 42 are relatively fixed to the adjusting body 10.

[0043] In this application, the flexible module 200 in the display screen can be a display module made of flexible material that can achieve morphological changes such as bending, folding, and stretching. This arc adjusting mechanism 100 can achieve the arc adjustment of the flexible module 200, so that the flexible module 200 is bent to the required radian of the user, meeting the personalized needs of the user.

[0044] It should be noted that in addition to the flexible module 200 in the display screen, the arc adjusting mechanism 100 of this application can also achieve the arc adjustment of components such as flexible circuit boards and flexible optical films.

[0045] For the arc adjusting mechanism 100 of this application, its overall structure is simple. The transmission design of the linkage member 42 and the adjusting arm 30 only requires a simple driving path, without multiple motors or complex transmission mechanisms, which can significantly simplify the structural complexity and operation difficulty. Moreover, the handle member 41 of this arc adjusting mechanism 100 integrates the functions of moving and rotating. By switching the handle member 41 between the first position and the second position, the bidirectional movement control of the adjusting arm 30 can be achieved, so that the adjusting arm 30 can move relatively closer to or farther away from the connecting arm 20, so that the flexible module 200 assumes a convex or concave arc shape, meeting the diverse arc adjustment needs of users.

[0046] In some embodiments of the present application, the adjustment body 10 includes a box body portion 11 and a cylinder body portion 12 connected to the box body portion 11. In the view direction of the drawings of the present application, the cylinder body portion 12 is connected to the bottom of the box body portion 11, and the interior of the cylinder body portion 12 communicates with the interior of the box body portion 11. The cylinder body portion 12 can be used as a handle to facilitate the user to hold the arc adjustment mechanism 100.

[0047] In some examples, the box body portion 11 includes a box body 111 and a box cover 112 connected to the box body 111. Among them, the box body 111 has a trough-shaped structure with an open top surface. The box cover 112 is arranged at the notch of the box body 111, and the cylinder body portion 12 is connected to the bottom of the box body 111.

[0048] The linkage 42 is arranged inside the box body portion 11, and the connecting arm 20 and the adjusting arm 30 are respectively arranged at both ends of the box body portion 11. There is a notch at the end of the box body portion 11, and the adjusting arm 30 is movably inserted through the notch of the box body portion 11. The connecting arm 20 is fixedly connected to the box body portion 11, and the connecting arm 20 and the box body portion 11 can be of an integrally formed structure. The end of the connecting arm 20 extends outwards beyond the side surface of the box body portion 11, and the surface of the connecting arm 20 for being fixedly connected to the flexible module 200 is the connecting surface.

[0049] In some embodiments of the present application, the linkage 42 is a gear, and a linkage tooth 421 is arranged on the outer periphery of the gear. An adjusting tooth 301 is arranged on the adjusting arm 30, and the adjusting tooth 301 is meshed and connected with the linkage tooth 421 of the linkage 42.

[0050] The linkage 42 is a gear, and the adjusting tooth 301 meshing with it is arranged on the adjusting arm 30. This gear meshing transmission method has high transmission accuracy and ensures the effectiveness of arc adjustment. When the handle member 41 rotates to drive the linkage 42 to rotate, through the precise cooperation of the linkage tooth 421 and the adjusting tooth 301, the power can be accurately transmitted to the adjusting arm 30, so that the adjusting arm 30 moves in the expected direction and distance, realizing the precise adjustment of the arc of the flexible module 200.

[0051] In some examples, the adjusting arm 30 includes an arm main body 31 and a connecting portion 32 arranged at one end of the arm main body 31. The connecting portion 32 is used for connecting with the surface of the flexible module 200, and the surface of the connecting portion 32 for connecting with the flexible module 200 is the fixing surface.

[0052] The arm main body 31 is arc-shaped, and an adjusting tooth 301 is arranged on the surface of the arm main body 31. In this example, the side wall of the box body is arranged in an arc shape adapted to the arm main body 31, and the arm main body 31 is attached to the side wall of the box body and can move along the side wall of the box body.

[0053] Setting the arm body 31 into an arc shape can make the transmission path more in line with the mechanical principles of arc adjustment. When the linkage 42 drives the adjustment arm 30 to move, the force can be more effectively transmitted to the flexible module 200, thereby improving the adjustment efficiency and better realizing the arc adjustment of the flexible module 200.

[0054] Furthermore, combined with Figure 4 As shown, the handle member 41 is rotatably disposed on the barrel portion 12. In some embodiments of the present application, the handle member 41 includes a gripping portion 411 and a transition portion 412 connected to the gripping portion 411, the transition portion 412 is disposed inside the barrel portion 12 and rotatably connected to the barrel portion 12, and the gripping portion 411 is disposed outside the barrel portion 12.

[0055] In this example, the gripping portion 411 is bent and connected to the adapter portion 412. The gripping portion 411 can be gripped by a user to realize movement of the handle 41 between the first position and the second position and rotation of the handle 41 relative to the adjustment body 10, so as to facilitate the user to operate the arc adjustment mechanism 100.

[0056] In some embodiments of the present application, the driving assembly 40 further includes a connecting rod 43 and a driving member 44, one end of the connecting rod 43 is rotatably connected to the handle member 41, and the other end of the connecting rod 43 is rotatably connected to the driving member 44. The driving member 44 is connected to the linkage member 42, and the handle member 41 rotates relative to the adjustment body 10 to drive the connecting rod 43 and the driving member 44 to rotate, so that the linkage member 42 rotates relative to the adjustment body 10, so that the linkage member 42 drives the adjustment arm 30 to move.

[0057] The user can precisely control the rotation angle of the handle member 41, and through the transmission and conversion of the connecting rod member 43 and the driving member 44, achieve fine control over the rotation of the linkage member 42, and then precisely adjust the moving distance of the adjustment arm 30 to achieve precise adjustment of the arc of the flexible module 200, thereby meeting the user's high requirements for the arc accuracy of the flexible module 200 in different scenarios.

[0058] In some examples, the driving member 44 includes a turntable portion 441 and a rod portion 442 connected to the turntable portion 441, the linkage member 42 is sleeved on the outside of the rod portion 442, and the end of the connecting rod member 43 is rotatably connected to one end of the rod portion 442 away from the turntable portion 441. In this example, the turntable portion 441 is arranged outside the box body 11, and the rod portion 442 is arranged inside the box body 11.

[0059] The driving member 44 further includes a locking portion 443, which is disposed on the surface of the rotating disk portion 441 provided with the rod portion 442. The adjusting body 10 is provided with a plurality of locking holes 101 arranged at intervals, and the locking portion 443 is engaged in the locking holes 101, so that the rotating disk portion 441 is locked on the adjusting body 10.

[0060] The locking part 443 cooperates with a plurality of spaced locking holes 101, and can fix the turntable part 441 at different positions, thereby limiting the rotation angle of the linkage 42. When it is necessary to adjust the arc of the flexible module 200, the user only needs to disengage the locking part 443 from the current locking hole 101, and then rotate the turntable part 441 to the target locking hole 101 and snap it, so as to fix the flexible module 200 at different arcs.

[0061] When the handle part 41 moves to the second position, the handle part 41 can pull the turntable part 441 through the link part 43, so that the locking part 443 is snapped in the locking hole 101, so that the turntable part 441 is fixed on the adjusting body 10, so that the handle part 41 and the linkage 42 are relatively fixed on the adjusting body 10, so that the flexible module 200 is positioned and fixed in the current arc state.

[0062] When the handle part 41 moves to the first position, the handle part 41 jacks up the turntable part 441 through the link part 43, so that the locking part 443 is disengaged from the current locking hole 101, thereby releasing the locking of the turntable part 441 and the adjusting body 10. At this time, the handle part 41 can rotate relative to the adjusting body 10 to drive the linkage 42 to rotate, so as to realize the arc adjustment of the flexible module 200.

[0063] In this example, a scale value is provided on the surface of the turntable part 441 facing away from the rod body part 442, and the scale value is used to correspondingly display the arc size of the bending of the flexible module 200.

[0064] Among them, the scale values on the turntable part 441 can correspond one by one to the positions of the locking holes 101, and each scale value can directly mark the bending arc of the flexible module 200. When the user rotates the turntable part 441 to make the locking part 443 snap into different locking holes 101, the scale value synchronously indicates the current arc state of the flexible module 200.

[0065] This kind of setting enables the user to directly judge whether the arc of the flexible module 200 after adjustment meets the expectation through the scale value without relying on experience or additional measuring tools. Moreover, the scale value clearly shows the arc corresponding to the current gear of the flexible module 200, which can effectively prevent repeated adjustment caused by excessive or insufficient rotation, and improve the operation efficiency.

[0066] In some embodiments of the present application, in combination with Figure 3 and Figure 4As shown, a boss 121 is protruded from the inner wall of the barrel portion 12, and a first positioning hole 4121 and a second positioning hole 4122 are provided at intervals on the side wall of the adapter portion 412. When the handle 41 is in the first position, the end of the boss 121 is clamped in the first positioning hole 4121, and when the handle 41 is in the second position, the end of the boss 121 is clamped in the second positioning hole 4122. The end of the boss 121 can be set in an arc shape to ensure that the boss 121 switches smoothly between the first positioning hole 4121 and the second positioning hole 4122.

[0067] During transportation or use, the close fit between the boss 121 and the positioning hole can prevent the curvature parameters of the flexible module 200 from changing due to vibration or accidental touch, thereby ensuring the stability of the overall structure of the flexible module 200. In addition, when the end of the boss 121 switches between the first positioning hole 4121 and the second positioning hole 4122, the user can sense the adjustment in place through touch (e.g., click sound or resistance change) and vision (e.g., alignment of the boss 121 with the positioning hole), without the need for additional confirmation steps, thereby quickly confirming that the handle 41 is in place at the first position or the second position.

[0068] In some examples, the first positioning hole 4121 and the second positioning hole 4122 are provided on the two opposite side walls of the adapter 412, and correspondingly, the barrel 12 is provided with two bosses 121, which are arranged opposite to each other. The symmetrical design of the two bosses 121 and the positioning holes on both sides avoids the problem of easy twisting of the single boss 121 structure, and further ensures the stability of the overall structure.

[0069] See also Figure 5 and Figure 6 In one embodiment of the present application, a display adjustment system 1000 is provided, which includes a flexible module 200 and an arc adjustment mechanism 100. The specific structure of the arc adjustment mechanism 100 has been described above and will not be repeated here. The display adjustment system 1000 may include at least two arc adjustment mechanisms 100, and at least two arc adjustment mechanisms 100 are connected to the flexible module 200 at intervals.

[0070] In some examples, the display adjustment system 1000 further includes at least three connecting frames, which are arranged on the flexible module 200 at intervals along the length direction of the flexible module 200, and the length direction of the connecting frame is consistent with the width direction of the flexible module 200. The connecting frame and the flexible module 200 can be fixed by magnetic connection. An arc adjustment mechanism 100 is connected between two adjacent connecting frames, and the connecting arm 20 of the arc adjustment mechanism 100 is connected to one of the connecting frames, and the adjustment arm 30 of the arc adjustment mechanism 100 is connected to another of the connecting frames. The connecting frame and the arc adjustment mechanism 100 can be fixed by matching the studs with the screw holes.

[0071] In this application, the three connecting brackets can be the first connecting bracket 301, the second connecting bracket 302, and the third connecting bracket 303 respectively. The first connecting bracket 301 and the third connecting bracket 303 are respectively arranged on both sides of the second connecting bracket 302.

[0072] There are two arc adjustment mechanisms 100. The connecting arm 20 of one of the arc adjustment mechanisms 100 is fixed to the first connecting bracket 301, and the adjustment arm 30 of this arc adjustment mechanism 100 is fixed to the second connecting bracket 302. The connecting arm 20 of the other arc adjustment mechanism 100 is fixed to the third connecting bracket 303, and the adjustment arm 30 of this arc adjustment mechanism 100 is fixed to the second connecting bracket 302.

[0073] In the display adjustment system 1000 of this application, when the user needs to perform arc adjustment of the flexible module 200, the three connecting brackets can be fixed to the flexible module 200 according to the above connection method first, and then two arc adjustment mechanisms 100 are correspondingly connected to the three connecting brackets respectively.

[0074] By driving the linkage 42 to rotate through the handle 41, when the adjustment arms 30 and the connecting arms 20 in the two arc adjustment mechanisms 100 move relatively away from each other, as Figure 7 shown, the flexible module 200 is in a concave arc shape. By driving the linkage 42 to rotate through the handle 41, when the adjustment arms 30 and the connecting arms 20 in the two arc adjustment mechanisms 100 move relatively closer to each other, as Figure 8 shown, the flexible module 200 is in a convex arc shape. By driving the linkage 42 to rotate through the handle 41, when the adjustment arm 30 of one of the arc adjustment mechanisms 100 moves relatively away from the connecting arm 20, while the adjustment arm 30 of the other arc adjustment mechanism 100 moves relatively closer to the connecting arm 20, as Figure 9 shown, the flexible module 200 is in an S-shaped arc.

[0075] For the arc adjustment mechanism and the display adjustment system of this application, the overall structure of the arc adjustment mechanism is simple. The transmission design between the linkage and the adjustment arm only requires a simple driving path, without multiple motors or complex transmission mechanisms, which can significantly simplify the structural complexity and operation difficulty. Moreover, the handle of this arc adjustment mechanism integrates the functions of moving and rotating. By switching the handle between the first position and the second position, two-way movement control of the adjustment arm can be achieved, so that the adjustment arm can move relatively closer to or away from the connecting arm, thereby making the flexible module in a convex or concave arc shape to meet the diverse arc adjustment needs of users.
