Abstract
Description
Technical Field
[0001] This invention relates to the field of display technology, and more particularly to a hinge structure and display device. Background Technology
[0002] With the development of organic light-emitting diode (OLED) display technology, and the fact that foldable display devices combine the portability of ordinary display devices with the ultimate experience of large-screen display when unfolded, foldable display devices have gradually become an important trend in the development of mobile terminals.
[0003] Currently, in existing foldable display devices, hinge structures are typically used to achieve the folding of flexible screens. As an important component of foldable electronic devices, the hinge structure plays a crucial role in screen protection and folding synchronization.
[0004] However, in the bending area of a foldable display device, both the flexible screen and the hinge structure need to be bent. Since the torsion arm and other rotating structures in the hinge structure are close to the flexible screen, when the display device vibrates or falls, the torsion arm and other rotating structures will collide and squeeze with the flexible screen, causing damage to the flexible screen. Summary of the Invention
[0005] This invention provides a hinge structure and display device that can increase the distance between the display panel and the first rotating member and the second rotating member, thereby reducing the probability of damage to the display panel.

[0021] The second support member includes a second floating plate and a second rotating plate connected to the second floating plate, and the second rotating plate is located on the side of the second floating plate away from the display panel. The second arc-shaped groove is disposed on the second rotating plate, and the second rotating member includes a second torque arm connected to the second arc-shaped groove.

The first torque arm, the third torque arm, the first cam portion, and the second cam portion are all sleeved on the first connecting rod, wherein the first torque arm is meshed with the first cam portion, and the third torque arm is meshed with the second cam portion.
[0023] The rotating assembly further includes a second connecting rod, a third cam portion, and a fourth cam portion disposed in the bracket.

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.
[0041] The following disclosure provides many different embodiments or examples for implementing various structures of the invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the invention. Furthermore, reference numerals and / or letters may be repeated in different examples; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, examples of various specific processes and materials are provided in this invention, but those skilled in the art will recognize the application of other processes and / or the use of other materials.
[0042] Please combine Figure 1 and Figure 2 In the folding display device provided by the related technology, a hinge and a flexible display panel 5 are included, and the flexible display panel 5 can be bent by the hinge. Specifically, the hinge includes a body 1, a floating plate 2 connected to the body 1, a rotating plate 3 connected to the floating plate 2, and a torque arm 4 connected between the rotating plate 3 and the body 1. The folding display device can switch between a flattened state and a folded state. When the folding display device switches between the flattened state and the folded state, the torque arm 4 can rotate 90° relative to the body 1, so that the rotating plate 3 rotates from parallel to the body 1 to perpendicular to the body 1. At this time, the flexible display panel 5 is bent and accommodated between the two floating plates 2. However, the distance between the flexible display panel 5 and the torque arm 4 is small. Therefore, when the folding display device is shaken or dropped, the rotating structure such as the torque arm 4 will collide and squeeze with the flexible display panel 5, causing damage to the flexible display panel 5.
[0043] Please combine Figure 3 and Figure 4 The present invention also provides a hinge structure 10, which includes a bracket 11, a linkage component 20, a rotation component 30, and a support component 40; the linkage component 20 is disposed in the bracket 11; the rotation component 30 includes a first rotating member 31 rotatably connected to one side of the linkage component 20 and a second rotating member 32 rotatably connected to the other side of the linkage component 20; the support component 40 includes a first support member 41 connected to the first rotating member 31 and a second support member 42 connected to the second rotating member 32.
[0044] Furthermore, the hinge structure 10 includes a flattened first state and a folded second state. In the second state, the first support member 41 and the second support member 42 rotate with the first rotating member 31 and the second rotating member 32 to form a bending accommodating space 110 between the first support member 41 and the second support member 42 to accommodate the display panel 60.
[0045] During the switching process between the first state and the second state of the hinge structure 10, the first rotating member 31 is slidably connected to the first support member 41 and the second rotating member 32 is slidably connected to the second support member 42 to control the rotation angle of the first rotating member 31 and the rotation angle of the second rotating member 32.
[0046] In practical application, this embodiment of the invention allows the first rotating member 31 to be slidably connected to the first support member 41 and the second rotating member 32 to be slidably connected to the second support member 42. Therefore, when the hinge structure 10 switches between the first and second states, the rotation angles of the first rotating member 31 and the second rotating member 32 can be controlled, ensuring that the first rotating member 31 and the second rotating member 32 have suitable rotation angles. This increases the distance between the first rotating member 31 and the display panel 60 in the second state (i.e., the folded state), as well as the distance between the second rotating member 32 and the display panel 60, reducing the probability of interference between the display panel 60 and the first rotating member 31 and the second rotating member 32, and decreasing the probability of damage to the display panel 60. This improves the yield rate of the display panel 60 using the hinge structure 10 provided in this embodiment of the invention.
[0047] Specifically, please continue to combine Figure 3 and Figure 4 The hinge structure 10 provided in this embodiment of the invention can be used for bending the display panel 60, and the display panel 60 can be disposed on the hinge structure 10, such as... Figure 3 As shown; it should be noted that, Figure 3 The hinge structure 10 shown has a partial display panel 60 formed on it. This is for illustrative purposes only and does not mean that the hinge structure 10 provided in this embodiment of the invention has a display panel 60 itself.
[0048] The display panel 60 can be bent by bending the hinge structure 10. The hinge structure can switch between a first state and a second state. The first state can be a flat state, in which both the hinge structure 10 and the display panel 60 are in a straight state. The second state can be a folded state, in which the hinge structure 10 bends to drive the display panel 60 to bend.
[0049] Furthermore, the hinge structure 10 includes a bracket 11, a linkage component 20 disposed in the bracket 11, a rotating component 30 connected to the linkage component 20, and a support component 40 connected to the rotating component 30.
[0050] The bracket 11 includes a fixing member 101, and the linkage assembly 20 includes a third link 21, a fourth link 22, multiple transmission gears 23, a third elastic member 24, and a fourth elastic member 25. The rotating assembly 30 includes a cam portion 37. The fixing member 101 and the cam portion 37 through which the third link 21 and the fourth link 22 pass serve to fix the third link 21 and the fourth link 22. The third elastic member 24 is sleeved on the third link 21 and abuts against the cam portion 37 and the bracket 11, and the fourth elastic member 25 is sleeved on the fourth link 22 and abuts against the cam portion 37 and the bracket 11. At least one transmission gear 23 is sleeved on the third link 21, and at least one transmission gear 23 is sleeved on the fourth link 22, and the transmission gears 23 on the third link 21 and the fourth link 22 are meshed together.
[0051] It should be noted that the third link 21 and the fourth link 22 can be fixedly connected to the fixing member 101 and the cam part 37, or they can rotate relative to the fixing member 101 and the cam part 37. That is, the third link 21 and the fourth link 22 can rotate with the transmission gear 23. The bracket 11 can be provided with a baffle parallel to the cam part 37 and the fixing member 101, and the third elastic member 24 and the fourth elastic member 25 can both abut against the baffle.
[0052] In one embodiment, both the third elastic element 24 and the fourth elastic element 25 may include springs.
[0053] The rotating assembly 30 includes a first rotating member 31 rotatably connected to one side of the linkage assembly 20 and a second rotating member 32 rotatably connected to the other side of the linkage assembly 20. Specifically, the first rotating member 31 can be rotatably connected to the third link 21, and the second rotating member 32 can be rotatably connected to the fourth link 22. That is, the first rotating member 31 can be connected to the third link 21 through the transmission gear 23, and the second rotating member 32 can be connected to the fourth link 22 through the transmission gear 23.
[0054] It is understandable that when the first rotating member 31 rotates, the transmission gear 23 on the third connecting rod 21 rotates. At the same time, the transmission gear 23 on the fourth connecting rod 22, which is meshed with the transmission gear 23 on the third connecting rod 21, rotates synchronously, which in turn drives the second rotating member 32 to rotate. The linkage assembly 20 enables the first rotating member 31 and the second rotating member 32 to rotate synchronously.
[0055] The support assembly 40 includes a first support member 41 connected to the first rotating member 31 and a second support member 42 connected to the second rotating member 32, and the first support member 41 and the second support member 42 rotate with the first rotating member 31 and the second rotating member 32, respectively.
[0056] When the hinge structure 10 is in the first flattened state, the display panel 60 and the hinge structure 10 are in a flattened state, that is, the side of the first support member 41 and the second support member 42 near the display panel 60 can be in a flattened state; when the hinge structure 10 is in the second folded state, the display panel 60 and the hinge structure 10 are in a folded state, that is, the first support member 41 and the second support member 42 rotate with the first rotating member 31 and the second rotating member 32, and form a bending accommodating space 110 between the first support member 41 and the second support member 42, so that the bent part of the display panel 60 can be accommodated in the bending accommodating space 110, so that the bent part of the display panel 60 can maintain a good bending shape, such as a teardrop shape.
[0057] The first support member 41 is provided with a first arc-shaped groove 401, and the second support member 42 is provided with a second arc-shaped groove 402. The first rotating member 31 can be slidably connected to the first arc-shaped groove 401, and the second rotating member 32 can be slidably connected to the second arc-shaped groove 402. The rotation and sliding trajectory of the first rotating member 31 and the second rotating member 32 are controlled by the first arc-shaped groove 401 and the second arc-shaped groove 402, so that when the hinge structure 10 switches between the first state and the second state, the rotation angle of the first rotating member 31 and the rotation angle of the second rotating member 32 are both less than 90°. This can increase the distance between the first rotating member 31 and the display panel 60 in the second state (i.e., the folded state), as well as the distance between the second rotating member 32 and the display panel 60, reducing the probability of interference between the display panel 60 and the first rotating member 31 and the second rotating member 32, and reducing the probability of damage to the display panel 60.
[0058] In one embodiment, please combine Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 as well as Figure 9The first rotating component 31 includes a first torque arm 311 and a third torque arm 312. The rotating assembly 30 also includes a first connecting rod 33, a first elastic element 35, a first cam portion 371, and a second cam portion 372. The first connecting rod 33 passes through the fixing member 101 and can be fixedly or rotatably connected to the fixing member 101. The first torque arm 311, the third torque arm 312, the first elastic element 35, the first cam portion 371, and the second cam portion 372 are all sleeved on the first connecting rod 33. The fixing member 101 is located between the first torque arm 311 and the third torque arm 312. The first torque arm 311 abuts against the fixing member 101 and the first cam portion 371 and engages with the first cam portion 371. The third torque arm 312 abuts against the fixing member 101 and the second cam portion 372 and engages with the second cam portion 372. The first elastic element 35 abuts against the baffle of the third torque arm 312 and the bracket 11. When the first torque arm 311 and the third torque arm 312 rotate, the cam on the first torque arm 311 will rotate and align with the cam on the first cam part 371, increasing the friction between the first torque arm 311 and the first cam part 371. The cam on the third torque arm 312 will rotate and align with the cam on the second cam part 372, and squeeze the first elastic element 35, increasing the friction between the third torque arm 312 and the second cam part 372. This increases the torque on the first rotating member 31 during rotation, allowing the first rotating member 31 to hover during rotation. This allows the hinge structure 10 to switch to the third state, which is a semi-folded state, meaning the degree of folding in the third state is less than that in the second state.
[0059] Furthermore, the first support member 41 includes a first floating plate 411 and a first rotating plate 412. The first rotating plate 412 is located on the side of the first floating plate 411 away from the display panel 60, and a first arc-shaped groove 401 is disposed on the side of the first rotating plate 412 away from the first floating plate 411. Simultaneously, a first torque arm 311 and a third torque arm 312 are both slidably connected within the first arc-shaped groove 401, and the first torque arm 311 and the third torque arm 312 slide synchronously. In one embodiment, the first torque arm 311 and the third torque arm 312 can be connected within the first arc-shaped groove 401. Additionally, a third arc-shaped groove 403 is provided on the first floating plate 411, and the third torque arm 312 is also slidably connected to the third arc-shaped groove 403.
[0060] The second rotating member 32 includes a second torque arm 321 and a fourth torque arm 322. The rotating assembly 30 also includes a second connecting rod 34, a second elastic element 36, a third cam portion 373, and a fourth cam portion 374. The second connecting rod 34 passes through the fixing member 101 and can be fixedly or rotatably connected to the fixing member 101. The second torque arm 321, the fourth torque arm 322, the second elastic element 36, the third cam portion 373, and the fourth cam portion 374 are all sleeved on the second connecting rod 34. The fixing member 101 is located between the second torque arm 321 and the fourth torque arm 322. The second torque arm 321 abuts against the fixing member 101 and the third cam portion 373 and engages with the third cam portion 373. The fourth torque arm 322 abuts against the fixing member 101 and the fourth cam portion 374 and engages with the fourth cam portion 374. The second elastic element 36 abuts against the baffle of the fourth torque arm 322 and the bracket 11. When the second torque arm 321 and the fourth torque arm 322 rotate, the cam on the second torque arm 321 will rotate and align with the cam on the third cam part 373, increasing the friction between the second torque arm 321 and the third cam part 373. Meanwhile, the cam on the fourth torque arm 322 will rotate and align with the cam on the fourth cam part 374, and press the second elastic element 36, increasing the friction between the fourth torque arm 322 and the fourth cam part 374. This increases the torque on the second rotating member 32 during rotation, allowing the second rotating member 32 to hover during rotation. This allows the hinge structure 10 to switch to the third state, which is a semi-folded state, meaning the degree of folding in the third state is less than that in the second state.
[0061] Furthermore, the second support member 42 includes a second floating plate 421 and a second rotating plate 422. The second rotating plate 422 is located on the side of the second floating plate 421 away from the display panel 60, and a second arc-shaped groove 402 is disposed on the side of the second rotating plate 422 away from the second floating plate 421. Simultaneously, the second torque arm 321 and the fourth torque arm 322 are both slidably connected within the second arc-shaped groove 402, and the second torque arm 321 and the fourth torque arm 322 slide synchronously. In one embodiment, the second torque arm 321 and the fourth torque arm 322 can be connected within the second arc-shaped groove 402. Additionally, the second floating plate 421 is provided with a fourth arc-shaped groove 404, and the fourth torque arm 322 is also slidably connected to the fourth arc-shaped groove 404.
[0062] In one embodiment, both the first elastic element 35 and the second elastic element 36 may include a spring.
[0063] In one embodiment, please combine Figure 3 , Figure 4 as well as Figure 5The first arc-shaped groove 401 includes a first end 4011 and a second end 4012. When the hinge structure 10 is in the first state, the distance between the first end 4011 and the display panel 60 is smaller than the distance between the second end 4012 and the display panel 60. The second arc-shaped groove 402 includes a third end 4021 and a fourth end 4022 that are disposed opposite to each other. In the first state, the distance between the third end 4021 and the display panel 60 is smaller than the distance between the fourth end 4022 and the display panel 60.
[0064] During the switching process between the first state and the second state of the hinge structure 10, the first rotating member 31 slides between the first end 4011 and the second end 4012 of the first arc groove 401, and the second rotating member 32 slides between the third end 4021 and the fourth end 4022 of the second arc groove 402. At the same time, the first rotating member 31 and the second rotating member 32 rotate relative to the linkage assembly 20.
[0065] Furthermore, in the first state of the hinge structure 10, the first rotating member 31 is connected to the first end 4011 of the first arc-shaped groove 401, and the second rotating member 32 is connected to the third end 4021 of the second arc-shaped groove 402; in the second state of the hinge structure 10, the first rotating member 31 is connected to the second end 4012 of the first arc-shaped groove 401, and the second rotating member 32 is connected to the fourth end 4022 of the second arc-shaped groove 402. Furthermore, when the hinge structure 10 is in the second folded state, since the second end 4012 expands outward relative to the first end 4011 toward the side away from the display panel 60, and the fourth end 4022 expands outward relative to the third end 4021 toward the side away from the display panel 60, the rotation angles of the first rotating member 31 and the second rotating member 32 can be limited, so that the rotation angles of the first rotating member 31 and the second rotating member 32 are both less than 90°. This increases the distance between the first rotating member 31 and the second rotating member 32 and the display panel 60, and reduces the probability of squeezing and colliding between the first rotating member 31 and the second rotating member 32 and the display panel 60.
[0066] It should be noted that, please refer to... Figure 3 , Figure 4 as well as Figure 6Both the first floating plate 411 and the second floating plate 421 are provided with clearance grooves 410, and the clearance grooves 410 are aligned with the first rotating member 31 and the second rotating member 32 to avoid interference between the first rotating member 31 and the second rotating member 32 and the first floating plate 411 and the second floating plate 421 respectively during the state switching process of the hinge structure 10. At the same time, the embodiment of the present invention also uses the first arc groove 401 and the second arc groove 402 to reduce the rotation angle of the first rotating member 31 and the second rotating member 32 to avoid the first rotating member 31 and the second rotating member 32 being squeezed and collided with the display panel 60 due to the close distance at the clearance groove 410.
[0067] In one embodiment, a fifth arc-shaped groove 405 is provided on the first rotating plate 412, and a first floating plate 411 is slidably connected to the fifth arc-shaped groove 405. A sixth arc-shaped groove 406 is provided on the second rotating plate 422, and a second floating plate 421 is slidably connected to the sixth arc-shaped groove 406. Therefore, when the hinge structure 10 switches between a first state and a second state, the first floating plate 411 can slide within the fifth arc-shaped groove 405, and the second floating plate 421 can slide within the sixth arc-shaped groove 406. In the second state, the connection between the first floating plate 411 and the first rotating plate 412 can slide to the side of the fifth arc-shaped groove 405 closer to the support 11, so that the end of the first floating plate 411 away from the support 11 can be closer to the second floating plate 421. Similarly, the connection between the second floating plate 421 and the second rotating plate 422 slides to the side of the sixth arc-shaped groove 406 closer to the support 11, so that the end of the second floating plate 421 away from the support 11 can be closer to the first floating plate 411. This allows for a smoother transition between the two states. Figure 1 In the related technologies shown, the width of the first floating plate 411 and the second floating plate 421 on the side away from the support 11 can be reduced, and the width of the first floating plate 411 and the second floating plate 421 on the side close to the support 11 can be increased, which can improve the bending shape of the display panel 60 located in the bending accommodating space 110, making it more perfect teardrop shape.
[0068] In one embodiment, the bracket 11 is provided with four sliding grooves 102, and the hinge structure 10 further includes a first connector 51, a second connector 52, a third connector 53, and a fourth connector 54 respectively disposed in the four sliding grooves 102, and the first connector 51, the second connector 52, the third connector 53, and the fourth connector 54 are all slidably connected to their respective sliding grooves 102; in addition, the support assembly 40 also includes a third rotating plate 43 and a fourth rotating plate 44, wherein the third rotating plate 43 is provided with a seventh arc-shaped groove, the fourth rotating plate 44 is provided with an eighth arc-shaped groove, and the first floating plate 411 is also slidably connected to the seventh arc-shaped groove, and the second floating plate 421 is also slidably connected to the eighth arc-shaped groove.
[0069] It should be noted that the fifth arc-shaped groove 405 and the seventh arc-shaped groove are respectively connected to the opposite sides of the first floating plate 411, and the sixth arc-shaped groove 406 and the eighth arc-shaped groove are respectively connected to the opposite sides of the second floating plate 421; and the first connecting piece 51 is connected between the first rotating plate 412 and the support 11, the second connecting piece 52 is connected between the third rotating plate 43 and the support 11, the third connecting piece 53 is connected between the second rotating plate 422 and the support 11, and the fourth connecting piece 54 is connected between the fourth rotating plate 44 and the support 11. As the first rotating plate 412, the third rotating plate 43, the second rotating plate 422 and the fourth rotating plate 44 rotate, the first connecting piece 51, the second connecting piece 52, the third connecting piece 53 and the fourth connecting piece 54 all slide in their respective corresponding sliding grooves 102 to cooperate with the state change of the hinge structure 10 switching between the first state and the second state.
[0070] In one embodiment, please combine Figure 4 and Figure 10 The hinge structure 10 includes a device area 120 and a wiring area 130 between the device area 120 and the device area 120. For example, there can be two device areas 120, and the linkage component 20, the rotation component 30 and the support component 40 are all set in the device area 120, which can reserve space in the wiring area 130. Thus, after the display panel 60 is assembled with the hinge structure 10, it can provide sufficient space for the FPC wiring of the display panel 60, avoiding insufficient space or conflict.
[0071] In summary, this embodiment of the invention provides a first arc-shaped groove 401 on the first support member 41 and a second arc-shaped groove 402 on the second support member 42, so that the first rotating member 31 is slidably connected to the first arc-shaped groove 401 and the second rotating member 32 is slidably connected to the second arc-shaped groove 402. Therefore, the rotation of the first rotating member 31 and the second rotating member 32 is controlled by the shapes of the first arc-shaped groove 401 and the second arc-shaped groove 402. Furthermore, in this embodiment, during the switching process between the first and second states of the hinge structure 10, since the rotation angles of both the first rotating member 31 and the second rotating member 32 are less than 90°, the rotation relative to... Figure 1 In the related technologies shown, the torque arm 4 needs to rotate 90°. In the embodiment of the present invention, the rotation angles of the first rotating member 31 and the second rotating member 32 are both less than 90°. This can increase the distance between the first rotating member 31 and the display panel 60 in the second state (i.e., the folded state) and the distance between the second rotating member 32 and the display panel 60, thereby reducing the probability of interference between the display panel 60 and the first rotating member 31 and the second rotating member 32, and reducing the probability of damage to the display panel 60.
[0072] Additionally, please combine Figure 3 , Figure 4and Figure 5 The present invention also provides a display device, which includes a display panel 60 and a hinge structure 10, and the display panel 60 can be disposed on the hinge structure 10.
