[0047] Referring to Figures 1-9 According to a first aspect of the present disclosure, a flexible screen folding mechanism is provided, which comprises a support assembly 20 and a transmission mechanism 30. The support assembly 20 is used to support a flexible screen 10 and comprises a first support plate 21 and a second support plate 22. The first support plate 21 and the second support plate 22 can be folded or unfolded relative to each other to drive the flexible screen 10 to fold or unfold. The transmission mechanism 30 is located between the first support plate 21 and the second support plate 22 and comprises a first transmission assembly 31 and a second transmission assembly 32.

[0061] As mentioned above, as shown in Figure 7 In the process of folding the first support plate 21 and the second support plate 22 relative to each other, the abutting piece 340 of the first transmission assembly 31 abuts against the first support plate 21, and the abutting piece 340 of the second transmission assembly 32 abuts against the second support plate 22, so as to rotate the first support plate 21 and the second support plate 22 from the vertical state to the inclined state to form an "eight" shape. In the process of rotating the first support plate 21 and the second support plate 22 from the vertical state to the inclined state, the first support plate 21 rotates relative to the first connecting assembly 41 and the second connecting assembly 42, and the second support plate 22 rotates relative to the third connecting assembly 43 and the fourth connecting assembly 44, and the rotation of the first support plate 21 and the second support plate 22 can be decomposed into a movement component along the width direction and a movement component along the thickness direction.

[0062] The first long hole 451 and the second long hole 461 both extend along the width direction of the first support plate 21, and the first connecting shaft 210 and the second connecting shaft 211 at both ends of the first support plate 21 are connected to the first long hole 451 and the second long hole 461 respectively, so that the first support plate 21 can move along the first long hole 451 and the second long hole 461; the first sliding groove 452 and the second sliding groove 462 both extend along the thickness direction of the first support plate 21, and the first movable block 45 and the second movable block 46 can slide relative to the sliding block 410 of the first connecting assembly 41 and the sliding block 410 of the second connecting assembly 42 through the first sliding groove 452 and the second sliding groove 462 respectively.

That is, in the process that the first support plate 21 is abutted by the abutting piece 340 of the first transmission assembly 31 and rotates relative to the first connecting assembly 41 and the second connecting assembly 42, the first support plate 21 drives the first connecting shaft 210 and the second connecting shaft 211 to move in the first long hole 451 and the second long hole 461 respectively, and drives the first movable block 45 and the second movable block 46 to slide relative to the sliding block 410 of the first connecting assembly 41 and the sliding block 410 of the second connecting assembly 42.

[0063] Similarly, the third long hole 471 and the fourth long hole 481 both extend along the width direction of the second support plate 22, and the third connecting shaft 220 and the fourth connecting shaft 221 at both ends of the second support plate 22 are connected to the third long hole 471 and the fourth long hole 481 respectively, so that the second support plate 22 can move along the third long hole 471 and the fourth long hole 481; the third sliding groove 472 and the fourth sliding groove 482 both extend along the thickness direction of the second support plate 22, and the third movable block 47 and the fourth movable block 48 can slide relative to the sliding block 410 of the third connecting assembly 43 and the sliding block 410 of the fourth connecting assembly 44 through the third sliding groove 472 and the fourth sliding groove 482 respectively.

That is, in the process that the second support plate 22 is abutted by the abutting piece 340 of the second transmission assembly 32 and rotates relative to the third connecting assembly 43 and the fourth connecting assembly 44, the second support plate 22 drives the third connecting shaft 220 and the fourth connecting shaft 221 to move in the third long hole 471 and the fourth long hole 481 respectively, and drives the third movable block 47 and the fourth movable block 48 to slide relative to the sliding block 410 of the third connecting assembly 43 and the sliding block 410 of the fourth connecting assembly 44.

[0064] Thus, in the process of folding the first support plate 21 and the second support plate 22, the abutting piece 340 of the first transmission assembly 31 abuts the first support plate 21, and the abutting piece 340 of the second transmission assembly 32 abuts the second support plate 22, so that the first support plate 21 and the second support plate 22 can move relative to the first connecting assembly 41, the second connecting assembly 42, the third connecting assembly 43 and the fourth connecting assembly 44, and rotate from the vertical state to the inclined state and form the "eight" shape.

Figures 1-3

[0066] The connecting body 400 of the first connecting assembly 41 and the connecting body 400 of the fourth connecting assembly 44 are each formed with a second moving groove 401 extending along the thickness direction of the first support plate 21 and the second support plate 22, and the second moving block 510 of the first moving assembly 50 is movably installed in the second moving groove 401 on the connecting body 400 of the first connecting assembly 41, and the second moving block 510 of the second moving assembly 51 is movably installed in the second moving groove 401 on the connecting body 400 of the fourth connecting assembly 44.

[0070] ​Secondly, in the process of rotating the first support plate 21 and the second support plate 22 relative to the first connecting assembly 41 and the fourth connecting assembly 44, the fifth connecting shaft 212 and the sixth connecting shaft 222 can also move relative to the first connecting assembly 41 and the fourth connecting assembly 44.

[0071] Specifically, the first moving assembly 50 and the second moving assembly 51 each include a first moving block 500 and a second moving block 510, the second moving block 510 is formed with a first moving slot 511 extending along the width direction, the first moving block 500 is movably installed in the first moving slot 511, the connecting body 400 of the first connecting assembly 41 and the connecting body of the fourth connecting assembly 44 are each formed with a second moving slot 401 extending along the thickness direction, the second moving block 510 of the first moving assembly 50 is movably installed in the second moving slot 401 on the connecting body 400 of the first connecting assembly 41, and the second moving block 510 of the second moving assembly 51 is movably installed in the second moving slot 401 on the connecting body 400 of the fourth connecting assembly 44. That is, the first moving block 500 can move in the first moving slot 511 along the width direction, and the second moving block 510 can move in the second moving slot 401 along the thickness direction. In the process of rotating the first support plate 21 and the second support plate 22 relative to the first connecting assembly 41 and the fourth connecting assembly 44 by the abutting piece 340 of the first transmission assembly 31 and the abutting piece of the second transmission assembly 32, the fifth connecting shaft 212 drives the first moving block 500 of the first moving assembly 50 to move in the first moving slot 511 along the width direction, and pushes the second moving block 510 of the first moving assembly 50 to move in the second moving slot 401 on the connecting body 400 of the first connecting assembly 41 along the thickness direction through the first moving block 500, so as to meet the rotation requirement of the first support plate 21 relative to the first connecting assembly 41; the sixth connecting shaft 222 drives the first moving block 500 of the second moving assembly 51 to move in the first moving slot 511 along the width direction, and pushes the second moving block 510 of the second moving assembly 51 to move in the second moving slot 401 on the connecting body 400 of the fourth connecting assembly 44 along the thickness direction through the first moving block 500, so as to meet the rotation requirement of the first support plate 21 relative to the fourth connecting assembly 44.

[0072] Optionally, as Figures 1-3As shown, the first driving assembly 31 can be provided with a seventh connecting shaft 341 on the abutting piece 340, and the seventh connecting shaft 341 is connected to the first moving block 500 of the first moving assembly 50. The second driving assembly 32 can be provided with an eighth connecting shaft 342 on the abutting piece 340, and the eighth connecting shaft 342 is connected to the first moving block 500 of the second moving assembly 51. The seventh connecting shaft 341 on the abutting piece 340 of the first driving assembly 31 is connected to the first moving block 500 of the first moving assembly 50, the eighth connecting shaft 342 on the abutting piece 340 of the second driving assembly 32 is connected to the first moving block 500 of the second moving assembly 51, and the fifth connecting shaft 212 on the first end of the first support plate 21 is also connected to the first moving block 500 of the first moving assembly 50. The sixth connecting shaft 222 on the second support plate 22 is also connected to the first moving block 500 of the second moving assembly 51, that is, the seventh connecting shaft 341 and the fifth connecting shaft 212 are connected to the same first moving block 500, and the eighth connecting shaft 342 and the sixth connecting shaft 222 are connected to the same first moving block 500. Thus, during the folding of the flexible screen folding mechanism, the first support plate 21 and the abutting piece 340 of the first driving assembly 31 can always move synchronously, and the second support plate 22 and the abutting piece 340 of the second driving assembly 32 can always move synchronously, so that the abutting piece 340 of the first driving assembly 31 can always abut against the first support plate 21, and the abutting piece 340 of the second driving assembly 32 can always abut against the second support plate 22, so that the first support plate 21 and the second support plate 22 can form an "eight" shape.

[0073] Optionally, as shown in Figure 1 , Figure 4 and Figure 7 , the flexible screen folding mechanism further comprises a first housing 2, a second housing 3 and a third housing 4. The second housing 3 is located between the first housing 2 and the third housing 4, and the first housing 2 and the third housing 4 are rotatably connected to the second housing 3, so that the first housing 2 and the third housing 4 can be folded or unfolded relative to each other. The first support plate 21 is arranged in the first housing 2, the second support plate 22 is arranged in the third housing 4, and the transmission mechanism 30 is arranged in the second housing 3. The first support plate 21 is arranged in the first housing 2, the second support plate 22 is arranged in the third housing 4, and the transmission mechanism 30 is arranged in the second housing 3. The first housing 2 and the third housing 4 can rotate around the second housing 3. During the folding of the flexible screen folding mechanism, pushing the first housing 2 and the third housing 4 can drive the first support plate 21 and the second support plate 22 to rotate, thereby driving the flexible screen 10 between the first support plate 21 and the second support plate 22 to bend and deform, and achieving the folding of the flexible screen folding mechanism.

[0074] In addition, a first mounting plate 5 is arranged on the inner side of the first shell 2 (i.e., the side of the first shell 2 close to the flexible screen 10), and a second mounting plate 6 is arranged on the inner side of the second shell 3 (i.e., the side of the second shell 3 close to the flexible screen 10), the first mounting plate 5 has a first mounting surface facing away from the first shell 2, and the second mounting plate 6 has a second mounting surface facing away from the second shell 3, and the flexible screen 10 is fixedly mounted on the first mounting surface and the second mounting surface.

[0075] As shown in Figure 1 , Figure 4 and Figure 9 , optionally, the flexible screen folding mechanism can further include dampers 60, the dampers 60 are mounted in the second shell 3 and connected with the first shell 2 and the third shell 4, and the dampers 60 are used to provide resistance when the first shell 2 and the third shell 4 are folded relative to each other. By arranging the dampers 60 on the second shell 3, the dampers 60 can generate a certain resistance during folding of the flexible screen folding mechanism, which can avoid loosening between the first shell 2 and the third shell 4, thereby facilitating the maintenance of the folding angle between the first shell 2 and the second shell 3.

[0076] In an embodiment provided by the present disclosure, the number of dampers 60 is two, and the two dampers 60 are mounted in the second shell 3 along the length direction of the first support plate 21 or the second support plate 22 (for details, refer to Figure 1 of course, the present disclosure does not limit the number of dampers 60, and the dampers 60 can also be one, three, four, etc., and the present disclosure does not limit this.

[0077] Here, it should be noted that the dampers 60 mentioned in the present application can be of any structure, as long as they can generate corresponding resistance during folding of the flexible screen terminal, and the present disclosure does not limit this, for example, in an embodiment provided by the present disclosure, as shown in Figure 9As shown, the damper 60 can include a rotating member 61, an elastic assembly 62 and a mounting seat 63. The rotating member 61 can include a connecting portion 610 and a sliding portion 611. The mounting seat 63 is formed with a sliding groove 630 and a mounting hole 631 communicating with the sliding groove 630. The sliding portion 611 is slidably mounted in the sliding groove 630. The elastic assembly 62 is mounted in the mounting hole 631 and can partially extend into the sliding groove 630. The first shell 2 and the third shell 4 are both provided with the rotating member 61. The first shell 2 and the third shell 4 are connected with the connecting portion 610 of the corresponding rotating member 61, respectively. The sliding portion 611 can slide in the sliding groove 630 and press the elastic assembly 62 towards the mounting hole 631 when the first shell 2 and the third shell 4 are relatively folded. In the folding process of the flexible screen folding mechanism, the first shell 2 and the third shell 4 relatively rotate, thereby driving the rotating member 61 provided in the first shell 2 and the third shell 4 to rotate. The rotating member 61 drives the sliding portion 611 to slide in the sliding groove 630 and press the elastic assembly 62 towards the mounting hole 631. In the process of pressing the elastic assembly 62, the elastic assembly 62 exerts a reverse elastic force on the sliding portion 611, so that the first shell 2 and the third shell 4 have the effect of elastic damping and the user can have a better experience of the feeling of stopping.

[0078] In an embodiment provided by the present disclosure, optionally, as Figure 9 The elastic assembly 62 can include a spring 620 and a top pin 621. The spring 620 is connected with the top pin 621 and is used to exert an elastic force on the top pin 621 to move the top pin 621 towards the sliding groove 630. The top pin 621 is used to contact the sliding portion 611. When the sliding portion 611 slides to the top pin 621 and presses against the top pin 621, the spring 620 is contracted under the pressure of the top pin 621 and exerts a reverse force on the top pin 621 under the action of the elastic force, so that the first shell 2 and the third shell 4 have the effect of elastic damping.

[0079] Of course, in other embodiments provided by the present disclosure, the elastic assembly can also be a torsion spring, a leaf spring or any other component that can meet the requirement of exerting an elastic force on the top pin 621 to move the top pin 621 towards the sliding groove 630, and the present disclosure does not limit this.

[0080] Optionally, as Figure 9As shown, the sliding part 611 is formed as an arc-shaped sliding part 611, and the sliding groove 630 is formed as an arc-shaped sliding groove 630. During folding of the flexible screen folding mechanism, the rotating track of the sliding part 611 is arc-shaped, and the sliding part 611 and the sliding groove 630 are both formed as arc-shaped, the shape of the sliding part 611 is matched with the space formed by the sliding groove 630, which facilitates the reciprocating sliding of the sliding part 611 in the sliding groove 630, and makes the cooperation between the sliding part 611 and the sliding groove 630 more closely, and improves the stability of the cooperation between the sliding part 611 and the sliding groove 630.

[0081] According to a second aspect of the present disclosure, a flexible screen terminal is provided, comprising a flexible screen 10 and the flexible screen folding mechanism as above, and the flexible screen 10 covers the first support plate 21 and the second support plate 22 of the flexible screen folding mechanism. The flexible screen terminal has all the beneficial effects of the above flexible screen folding mechanism, and the present disclosure will not repeat it here.

[0082] The preferred embodiments of the present disclosure are described in detail above with reference to the accompanying drawings, but the present disclosure is not limited to the specific details in the above embodiments, and various simple modifications can be made to the technical solutions of the present disclosure within the technical concept of the present disclosure, and these simple modifications all belong to the protection scope of the present disclosure.

[0083] In addition, it should be noted that each specific technical feature described in the above specific embodiments can be combined in any appropriate manner without contradiction, and in order to avoid unnecessary repetition, the present disclosure will not further describe various possible combination manners.

[0084] In addition, various different embodiments of the present disclosure can also be combined in any manner, as long as it does not deviate from the idea of the present disclosure, it should also be considered as disclosed by the present disclosure.
