Description

Technical Field

[0001] The present application relates to the field of flexible screen scale adjustment, and in particular to a flexible screen scale control mechanism. Background Art

[0002] Flexible screen refers to flexible OLED, which has the characteristics of bending and folding, making it widely used in outdoor display fields such as advertising displays.

[0003] Existing curved display screens generally achieve curved display of the flexible screen by fixing the flexible screen on the curved surface or cut edge of a box, thereby achieving the effect of curved display.

[0004] For the above-mentioned related technologies, it is necessary to customize a specific steel frame structure to achieve the curved display of the flexible screen. Different curved radius requires customization of different steel structures. The versatility is poor and it is not easy to quickly adjust the scale of the flexible screen according to different usage requirements. Utility Model Content

[0005] In order to improve the scale adjustment efficiency of the flexible screen, the present application provides a flexible screen scale control mechanism.

[0006] The flexible screen scale control mechanism provided in this application adopts the following technical solutions:

[0007] A flexible screen scale control mechanism includes a control body and a control assembly, wherein the control body includes a main body and two adjustment parts, and the two adjustment parts are respectively fixedly arranged at both ends of the main body;

[0008] The control assembly includes two adjustment blocks and two adjustment rods. The two adjustment blocks are respectively slidably matched with the two adjustment parts. The sliding trajectories of the two adjustment blocks are both arc-shaped. The two adjustment blocks are fixedly provided with adjustment racks. The two adjustment rods are provided on the control body and are respectively located on both sides of the control body. The two adjustment rods are respectively abutted and matched with the two adjustment blocks. The two adjustment rods are fixedly provided with adjustment teeth.

[0009] When the control assembly is in a locked state, the two adjusting teeth are respectively engaged with the two adjusting racks. When there is an external force to cause the two adjusting teeth to be disengaged from the two adjusting racks, the control assembly changes from a locked state to an unlocked state.

[0010] By adopting the above technical solution, when the scale of the flexible screen needs to be adjusted quickly, the two adjusting rods are disengaged from the abutment cooperation with the two adjusting blocks respectively, thereby driving the two adjusting teeth to be disengaged from the engagement with the two adjusting racks respectively, so that the control component is changed from a locked state to an unlocked state, so that the cooperation between the two adjusting blocks and the control body is changed from relatively fixed to relatively sliding, so that the two adjusting blocks slide toward or away from the two adjusting parts respectively, thereby completing the scale adjustment of the end of the adjusting block and the adjusting part that is away from each other, thereby realizing rapid adjustment of the scale of the flexible screen, improving the problem of needing to customize a specific steel frame structure to achieve curved display of the flexible screen, different curved radius requires customization of different steel structures, poor versatility and difficulty in rapid adjustment of the scale of the flexible screen according to different usage requirements.

[0011] Optionally, the two adjustment rods are rotatably arranged on the main body and are respectively located on both sides of the main body close to the two adjustment parts. When the two adjustment rods are rotated away from the two adjustment blocks, the two adjustment teeth are disengaged from the two adjustment racks.

[0012] By adopting the above technical solution, the two adjusting rods are rotatably arranged on the main body, so that when the two adjusting rods need to be disengaged from the abutment with the two adjusting blocks, the two adjusting rods are respectively rotated in the direction away from the two adjusting blocks until the two adjusting rods are respectively disengaged from the abutment with the two adjusting blocks, thereby respectively driving the two adjusting teeth to respectively disengage from the engagement with the two adjusting racks, thereby making it easier and more convenient for the control component to change from a locked state to an unlocked state, and making it more usable.

[0013] Optionally, the control component also includes two reset torsion springs, one end of each of the reset torsion springs is fixedly connected to the main body, and the other end of each of the reset torsion springs is fixedly connected to the two adjusting rods. When there is no external force to rotate the two adjusting rods, the two reset torsion springs respectively drive the two adjusting rods to rotate toward the direction close to the two adjusting blocks.

[0014] Optionally, the two adjustment rods each include a first rod portion and a second rod portion, the first rod portion is fixedly connected to the adjustment tooth body, the second rod portion is fixedly connected to the first rod portion, and both second rod portions are provided with an adjustment slot extending therethrough, and the two adjustment slots are connected to each other;

[0015] The control assembly also includes a driving rod, which passes through the two adjustment slots and slides into the main body. When the driving rod slides toward or away from the main body, the two second rod bodies rotate toward or away from the main body, and the two first rod bodies rotate toward or away from the two adjustment blocks respectively.

[0016] By adopting the above technical solution, the driving rod passes through the two adjusting slots at the same time, so that when the driving rod slides toward or away from the main body, the driving rod simultaneously drives the two second rod bodies to rotate toward or away from the main body, thereby realizing synchronous driving of the two adjusting rods. At the same time, when the two reset torsion springs respectively drive the two adjusting rods to reset, the two adjusting rods are connected by the driving rod to achieve simultaneous reset, thereby making the unlocking or locking of the control component more synchronized, making the locking or unlocking of the control component simpler and more convenient, and making it more usable.

[0017] Optionally, the main body is provided with a sliding groove, the driving rod is passed through and slidingly engaged with the sliding groove, and the length direction of the sliding groove is arranged along the Y-axis direction of the main body.

[0018] By adopting the above technical solution and setting the sliding groove, the sliding trajectory of the driving rod is made more stable, thereby making the rotation of the two adjusting rods more synchronous and improving the usability.

[0019] Optionally, the control component also includes a drive plate, which is rotatably arranged on the main body. The drive plate includes a plate body and at least one drive part. The drive part is fixedly arranged at one end of the plate body, and the drive part is in contact with the drive rod. When the plate body rotates, the drive part drives the drive rod to slide.

[0020] By adopting the above technical solution, the driving plate is set so that when the driving rod needs to slide, the plate body rotates, the rotation of the plate body drives the driving part to rotate, and the rotation of the driving part drives the driving rod to slide, thereby realizing the driving of the driving rod to slide, making the driving of the driving rod to slide simpler and more convenient, and making it more usable.

[0021] Optionally, the driving plate further includes a pressing portion, which is fixedly disposed at one end of the plate body away from the driving portion. When an external force presses the pressing portion, the plate body rotates and the control assembly is unlocked.

[0022] By adopting the above technical solution, the pressing part is set so that when the plate body needs to be rotated, the external force presses the pressing part, so that the pressing part rotates toward the main body, thereby driving the plate body to rotate, making the driving of the plate body simpler and more convenient, and making it more usable.

[0023] Optionally, when the control assembly is locked, the pressing portion is parallel to one side of the main body.

[0024] Optionally, both adjustment blocks are fixedly provided with sliding protrusions, and both adjustment parts are provided with penetrating adjustment grooves, and the two sliding protrusions are respectively passed through and slidably fitted in the two adjustment grooves.

[0025] By adopting the above technical solution, the setting of the sliding protrusion and the sliding groove makes the sliding cooperation between the two adjustment blocks and the two adjustment parts more stable, thereby making the control mechanism have a better adjustment effect on the flexible screen scale.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. When the scale of the flexible screen needs to be adjusted quickly, the two adjusting rods are disengaged from the abutment between the two adjusting blocks, thereby driving the two adjusting teeth to disengage from the engagement with the two adjusting racks, so that the control component is changed from a locked state to an unlocked state, so that the cooperation between the two adjusting blocks and the control body is changed from relatively fixed to relatively sliding, so that the two adjusting blocks slide toward or away from the two adjusting parts respectively, thereby completing the scale adjustment of the end of the adjusting block and the adjusting part that is away from each other, thereby realizing rapid adjustment of the scale of the flexible screen, improving the problem of needing to customize a specific steel frame structure to achieve curved display of the flexible screen, different curved radius requires customization of different steel structures, poor versatility and difficulty in quickly adjusting the scale of the flexible screen according to different usage requirements.

[0028] 2. The two adjusting rods are rotatably arranged on the main body, so that when the two adjusting rods need to be disengaged from the abutment with the two adjusting blocks, the two adjusting rods are respectively rotated in the direction away from the two adjusting blocks until the two adjusting rods are respectively disengaged from the abutment with the two adjusting blocks, thereby respectively driving the two adjusting teeth to be disengaged from the engagement with the two adjusting racks, thereby making it easier and more convenient to change the control component from the locked state to the unlocked state, making it more usable.

[0042] The following is combined with Figure 1-11 This application is described in further detail.

[0043] The embodiment of the present application discloses a flexible screen scale control mechanism. Figure 1 and Figure 2 A flexible screen scale control mechanism includes a control body 1 and a control component 2, and the control component 2 is arranged on the control body 1.

[0044] Reference Figure 1 and Figure 2 The control body 1 includes a main body 11 and two adjustment parts 12. The cross-section of the main body 11 is rectangular. In the embodiment of the present application, the length direction of the main body 11 is set as the X-axis direction, and the width direction of the main body 11 is set as the Y-axis direction. The two adjustment parts 12 are respectively fixed at the two ends of the main body 11 in the X-axis direction.

[0045] Reference Figure 1 and Figure 3The control component 2 includes two adjustment blocks 21, which are respectively slidably fitted on one side of the bottom of the two adjustment parts 12. The sliding trajectories of the two adjustment blocks 21 are both arc-shaped. The two adjustment blocks 21 are fixedly provided with sliding protrusions 211 on one side close to the two adjustment parts 12. The two adjustment parts 12 are provided with a penetrating adjustment groove 121. The groove body of the adjustment groove 121 extends along the arc of the adjustment part 12. The two sliding protrusions 211 are respectively penetrated and slidably fitted in the two adjustment grooves 121. An adjustment rack 212 is fixedly provided on one side of the bottom of the two adjustment blocks 21.

[0046] Reference Figure 4 The control assembly 2 also includes two adjusting rods 22, which are rotatably arranged on the main body 11 and are respectively located on both sides of the main body 11 close to the two adjusting parts 12. The two adjusting rods 22 are respectively abutted and matched with the two adjusting blocks 21. The two adjusting rods 22 include a first rod body portion 221 and a second rod body portion 222. The first rod body portion 221 and the second rod body portion 222 are fixedly connected, and the two second rod bodies 222 are located close to each other at one end and the two second rod bodies 222 abut and match each other. The two first rod bodies 221 are located at one end away from each other, and the two first rod bodies 221 are fixedly provided with an adjusting tooth body 2211 on one side close to the two adjusting blocks 21.

[0047] Reference Figure 5 and Figure 6 , the two adjusting teeth 2211 are respectively engaged with the two adjusting racks 212, the control assembly 2 is in a locked state, and the two adjusting blocks 21 are respectively fixed relative to the two adjusting parts 12;

[0048] Reference Figure 7 and Figure 8 When the two adjusting teeth 2211 are disengaged from the two adjusting racks 212 respectively, the control assembly 2 is in an unlocked state, and the two adjusting blocks 21 and the two adjusting parts 12 are respectively transformed from being relatively fixed to being relatively sliding.

[0049] The two adjusting rods 22 are rotatably arranged on the main body 11, so that when the two adjusting rods 22 need to be disengaged from the abutment with the two adjusting blocks 21, the two adjusting rods 22 are respectively rotated in the direction away from the two adjusting blocks 21 until the two adjusting rods 22 are respectively disengaged from the abutment with the two adjusting blocks 21, thereby respectively driving the two adjusting teeth 2211 to respectively disengage from the engagement with the two adjusting racks 212, thereby making it easier and more convenient for the control component 2 to change from the locked state to the unlocked state.

[0050] Reference Figure 9The control assembly 2 also includes two return torsion springs 23, one end of each of the return torsion springs 23 is fixedly connected to the main body 11, and the other ends of the two return torsion springs 23 are respectively fixedly connected to the two adjustment rods 22. When there is no external force to rotate the two adjustment rods 22, the two return torsion springs 23 respectively drive the two adjustment rods 22 to rotate toward the two adjustment blocks 21, thereby changing the control assembly 2 from the unlocked state to the locked state.

[0051] Reference Figure 9 and Figure 10 The two second rod bodies 222 are both provided with an adjustment groove 2221 that is set through, and the two adjustment grooves 2221 are connected to each other. The control component 2 also includes a driving rod 24, and the driving rod 24 passes through the two adjustment grooves 2221. The main body 11 has sliding grooves 111 set through on both sides in the thickness direction. The length of the sliding groove 111 is set along the Y-axis direction. The two ends of the driving rod 24 are respectively passed through and slidably matched with the two sliding grooves 111.

[0052] Reference Figure 9 and Figure 10 , so that when the driving rod 24 slides along the length direction of the sliding groove 111 toward or away from the main body 11, the driving rod 24 simultaneously drives the two second rod bodies 222 to rotate toward or away from the main body 11, thereby realizing synchronous driving of the two adjusting rods 22. At the same time, when the two reset torsion springs 23 respectively drive the two adjusting rods 22 to reset, the two adjusting rods 22 are connected through the driving rod 24 to achieve simultaneous reset, thereby making the unlocking or locking of the control component 2 more synchronized, thereby making the locking or unlocking of the control component 2 simpler and more convenient.

[0053] Reference Figure 11 The control component 2 also includes a driving plate 25, which includes a plate body 251, two driving parts 252 and a pressing part 253.

[0054] Reference Figure 11 When the driving rod 24 needs to slide along the length direction of the sliding groove 111 toward the main body 11, the pressing part 253 is pressed, so that the pressing part 253 rotates toward the main body 11, thereby driving the plate body 251 to rotate, thereby driving the two driving parts 252 to rotate toward the main body 11, thereby pushing the driving rod 24 to slide along the length direction of the sliding groove 111 toward the main body 11, thereby completing the driving of the driving rod 24 to slide. When the two reset torsion springs 23 drive the driving rod 24 to reset, the driving rod 24 pushes the driving plate 25 to reset.

[0055] The implementation principle of a flexible screen scale control mechanism in an embodiment of the present application is as follows: when the flexible screen scale needs to be adjusted quickly, the two adjusting rods 22 are respectively rotated in the direction away from the two adjusting blocks 21, thereby driving the two adjusting teeth 2211 to rotate in the direction away from the two adjusting racks 212, so that the two adjusting teeth 2211 are respectively disengaged from the two adjusting racks 212, thereby changing the control component 2 from a locked state to an unlocked state, thereby changing the cooperation between the two adjusting blocks 21 and the control body 1 from relatively fixed to relatively sliding, thereby completing the scale adjustment of the end of the adjusting block 21 and the adjusting part 12 that is away from each other through the two adjusting blocks 21 respectively sliding in the direction of approaching or away from the two adjusting parts 12, thereby realizing rapid adjustment of the flexible screen scale, improving the problem that a specific steel frame structure needs to be customized to achieve curved display of the flexible screen, different curved surface radii require customization of different steel structures, poor versatility, and difficulty in rapid scale adjustment of the flexible screen according to different usage requirements.
