SUMMARY
[0005] Embodiments of the present application provide a rotating mechanism and a folding display terminal, which solve the problem of arching of the flexible screen.

In this way, the first rotating connection part is arranged in the first guide, and the second rotating connection part is arranged in the second guide, which can protect the first rotating connection part and the second rotating connection part.

Thus, by providing the first connecting rod shaft and the second connecting rod shaft, the rotating speed of the first support component and the second support component can be controlled to avoid the flexible screen being pulled due to the first support component and the second support component rotating too fast or too slow, and further avoid the flexible screen from arching.

Thus, the first connecting rod shaft and the second connecting rod shaft are inserted into the tracks of the first rotating member and the second rotating member respectively, the rotational axis of the first rotating member and the second rotating member is different from the rotational axis of the first connecting rod shaft and the second connecting rod shaft, the first rotating member and the first connecting rod shaft form a crank slider mechanism, the second rotating member and the second connecting rod shaft form a crank slider mechanism, and through the rotation of the first rotating member and the second rotating member, the first connecting rod shaft and the second connecting rod shaft can be rotated, so that the speed of the support component and the rotating member is adapted, avoiding the flexible screen being pulled due to the first support component and the second support component rotating too fast or too slow, and further avoiding the flexible screen from arching.
[0013] In an alternative implementation, the first connecting rod shaft and the second connecting rod shaft are Y-shaped structures. Thus, it is convenient to connect the rotating shaft, the rotating member and the support component to form a crank slider mechanism.

Thus, the synchronization of the first connecting rod shaft and the second connecting rod shaft is realized.
[0015] In an alternative implementation, the transmission mechanism comprises a first gear sleeved on the first rotating shaft, a third gear sleeved on the third rotating shaft, a fourth gear sleeved on the fourth rotating shaft, and a second gear sleeved on the second rotating shaft; the first gear and the third gear are engaged, the third gear and the fourth gear are engaged, and the fourth gear and the second gear are engaged. Thus, the synchronization of the first connecting rod shaft and the second connecting rod shaft is realized.
[0016] In an alternative implementation, the rotating shaft further comprises a guide outer shaft, which covers the third rotating shaft and the fourth rotating shaft; wherein the lengths of the third rotating shaft and the fourth rotating shaft are less than the length of the guide outer shaft, the second end of the length direction of the guide outer shaft extends along the length direction relative to the first end of the length direction of the guide outer shaft, and the third rotating shaft and the fourth rotating shaft are arranged between the first end of the length direction of the guide outer shaft and the second end of the length direction of the guide outer shaft. Thus, the third rotating shaft and the fourth rotating shaft are arranged in the guide outer shaft, and the third rotating shaft and the fourth rotating shaft are protected.
[0017] In an alternative implementation, the outer side surfaces of the third rotating shaft and the fourth rotating shaft and the inner side surfaces of the guide outer shaft form a slide; the first rotating member is arranged on the first rotating element, and the second rotating member is arranged on the second rotating element; the first rotating member and the second rotating member are located in the slide; when the first rotating element and the second rotating element rotate around the rotating shaft, the first rotating member rotates around the third rotating shaft in the slide, and the second rotating member rotates around the fourth rotating shaft in the slide.

[0032] In order to make the purposes, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings.
[0033] Hereinafter, the terms "first", "second", and the like are only used for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined with "first", "second", and the like can explicitly or implicitly include one or more of the features. In the description of the present application, unless otherwise stated, the meaning of "a plurality of" is two or more.
[0034] In addition, in the present application, the orientation terms such as "upper", "lower", and the like are defined with respect to the orientation in which the components in the drawings are placed, and it should be understood that these directional terms are relative concepts, which are used for relative description and clarification, and can be changed accordingly according to the change of the orientation in which the components are placed in the drawings.
[0035] As Figure 1a shown, the folding display terminal 01 includes a flexible screen 10. The flexible screen 10 can be an active matrix organic light emitting diode (AMOLED) display screen.
[0036] The AMOLED display screen, as a self-luminous display screen, does not need to be provided with a back light module (BLM). Therefore, when the substrate substrate in the AMOLED display screen is made of a flexible resin material, such as polyethylene terephthalate (PET), the AMOLED display screen can have a bendable characteristic.
[0037] In addition, as Figure 1a shown, the folding display terminal 01 further includes a rotating mechanism 20 for carrying the flexible screen 10.
[0038] The rotating mechanism 20 includes a first support component 201, a second support component 202, a third support component 203 located between the first support component 201 and the second support component 202, and a first rotating member 204 provided on one side of the first support component 201, and a second rotating member 205 provided on one side of the second support component 202.
[0039] The first rotating member 204 and the second rotating member 205 can be a shell, or a middle frame structure of an electronic device.
[0040] The first support component 201 and the second support component 202 can be door panels, the first support component 201 is arranged on the first rotating member 204 and is in sliding connection with the first rotating member 204, and the second support component 202 is arranged on the second rotating member 205 and is in sliding connection with the second rotating member 205, and the third support component 203 can be an intermediate panel.
[0041] The first rotating member 204 and the second rotating member 205 can be used to bear the flexible screen 10, so that the flexible screen 10 is kept as flat as possible during use and the non-display surface of the flexible screen 10 is protected.
[0042] A part of the flexible screen 10 is fixed to the first rotating member 204 through a glue layer 30, and a part of the flexible screen 10 is fixed to the second rotating member 205 through the glue layer 30. The glue layer 30 can be a thin film layer formed after glue is applied, and the specific form of the glue layer 30 is not limited in the embodiments of the present application. In addition, other electronic elements such as a camera, an earphone, a receiver, a key, a battery, etc. can also be arranged on the first rotating member 204 and the second rotating member 205, and the other electronic elements arranged on the first rotating member 204 and the second rotating member 205 are not limited in the embodiments of the present application.
[0043] The first rotating member 204 and the second rotating member 205 can rotate along the axis of the folding display terminal 01 respectively, so as to drive the flexible screen 10 to fold or unfold.
[0044] As shown in FIG. 1, Figure 1a the flexible screen can be folded and unfolded, wherein, Figure 1a from 180° to 0°, Figure 1b from 0° to 180°.
[0045] However, in the case that the first rotating member 204 and the second rotating member 205 do not have the folding characteristic, the area of the flexible screen 10 connected with the first rotating member 204 and the second rotating member 205 through the glue layer will be pulled when folding and unfolding, the first support component 201, the second support component 202 and the third support component 203 cannot be completely attached to the flexible screen 10, so that the part of the flexible screen 10 opposite to the first support component 201, the second support component 202 and the third support component 203 is arched, which affects the flatness of the flexible screen.
[0046] As shown in FIG. 2, Figure 1a when the included angle α between the first rotating member 204 and the second rotating member 205 is 0°, the flexible screen 10 is in a folded state. During the process of rotating from unfolding to folding, the flexible screen 10 will be curved upward, causing reverse arching.
[0047] or, as shown in FIG. 3, Figure 1bAs shown, when the included angle a between the first rotating member 204 and the second rotating member 205 increases from 0° to 180°, the flexible screen 10 is in an unfolded state. When the flexible screen 10 is in a folded state for a long time, the flexible screen 10 will be deformed, and when it is unfolded again, the flexible screen 10 will become an "M" shape.
[0048] Therefore, during the folding or unfolding of the flexible screen 10, the first supporting member 201, the second supporting member 202, and the flexible screen 10 need to be attached to avoid the arching of the flexible screen 10.
[0049] In some embodiments, as shown in Figure 2a Figure 2b A part of the flexible screen 10 can be fixed on the first supporting member 201 through the adhesive layer 30, and a part of the flexible screen 10 can be fixed on the second supporting member 202 through the adhesive layer 30.
[0050] However, in the case where the first supporting member 201 and the second supporting member 202 do not have the bending characteristic, the area of the flexible screen 10 connected to the first supporting member 201 and the second supporting member 202 through the adhesive layer will be subjected to a pulling force during folding and unfolding, affecting the flatness of the flexible screen 10.
[0051] As shown in Figure 3 Figure 3a The rotating shaft of the first supporting member 201 and the second supporting member 202 is designed as a solid shaft, for example, and the rotating axis O of the first supporting member 201 and the second supporting member 202 is far away from the flexible screen 10. If the first supporting member 201 and the flexible screen 10 are attached, during the rotation process, the first supporting member 201 will pull the flexible screen 10 to move to the right, causing the flexible screen 10 to be unable to be attached to the first rotating member 204.
[0052] Therefore, an improved rotating mechanism is provided in the embodiments of the present application.
[0053] As shown in Figure 4 Figure 4a The rotating mechanism comprises a first supporting member 201 and a second supporting member 202.
[0054] Further comprising a first rotating member 204, a rotating shaft 200, and a second rotating member 205. The first rotating member 204 is rotatably connected to the second rotating member 205 through the rotating shaft 200.
[0055] The first supporting member 201 is arranged on a first surface of the first rotating member 204, and the second supporting member 202 is arranged on a first surface of the second rotating member 205. The first supporting member 201 and the first rotating member 204 are slidingly connected, and the second supporting member 202 and the second rotating member 205 are slidingly connected.
[0056] When the first rotating member 204 and the second rotating member 205 rotate around the rotating shaft 200, the first supporting member 201 and the second supporting member 202 rotate accordingly, and the first supporting member 202 slides along the surface of the first rotating member 204, and the second supporting member 202 slides along the surface of the second rotating member 205.
[0057] The rotation axes of the first support component 201 and the second support component 202 are higher than the rotation axis of the rotating shaft 200.
[0058] In some embodiments of this application, the rotation axis O' of the first support member 201 and the second support member 202 is located in the plane of the flexible screen 10.
[0059] The rotating mechanism provided in this application embodiment adopts a virtual axis design for the rotation axes of the first support component 201 and the second support component 202. The rotation axis O' of the first support component 201 and the second support component 202 is located in the plane where the flexible screen 10 is located, so that the first support component 201 and the second support component 202 can simultaneously fit with the flexible screen 10 during rotation, reducing the pulling force generated on the flexible screen 10 when the first support component 201 and the second support component 202 rotate, and avoiding the arching of the flexible screen 10 caused by pulling.
[0060] This application does not limit the specific structure of the virtual axis. In some embodiments of this application, the first support member 201 and the second support member 202 have an arc-shaped rotating connection portion at the end away from the rotating shaft 200. The central angle occupied by the arc-shaped rotating connection portion is less than 180°, so that the rotation axis of the arc-shaped rotating connection portion is higher than the rotation axis of the rotating shaft.
[0061] Accordingly, the first rotating member 204 and the second rotating member 205 include arc-shaped guide members. The arc-shaped guide members are disposed on the outer side of the rotating connection portion. When the first rotating member 204 and the second rotating member 205 rotate around the rotating shaft 200, the rotating connection portion rotates within the guide members.
[0062] like Figure 4 As shown, the first support member 201 and the second support member 202 respectively include a first end and a second end opposite to each other. The first end of the first support member 201 is close to the first end of the first rotating member 204, and the second end of the first support member 201 is provided with the first rotating connection portion 2011. The first end of the second support member 202 is close to the first end of the second rotating member 205, and the second end of the second support member 202 is provided with the second rotating connection portion 2021.
[0063] The first rotation connecting part 2011 and the second rotation connecting part 2021 are in the shape of a circular arc, wherein the central angle of the first rotation connecting part 2011 and the second rotation connecting part 2021 is less than 180°.
[0064] Thus, the rotation of the first support part 201 and the second support part 202 around the virtual axis is realized. The central angle of the first rotation connecting part 2011 and the second rotation connecting part 2021 is less than 180°, and the rotation axis of the first rotation connecting part 2011 and the second rotation connecting part 2021 is higher than the plane where the first support part 201 and the second support part 202 are located.
[0065] Next, referring to Figure 4 The first rotating part 204 comprises a first guide part 2041, and the second rotating part 205 comprises a second guide part 2051.
[0066] The first rotating part 204 and the second rotating part 205 respectively comprise opposite first ends and second ends. The first end of the first rotating part 204 is rotationally connected with the rotating shaft 200, and the second end of the first rotating part 204 is provided with the first guide part 2041. The first end of the second rotating part 205 is rotationally connected with the rotating shaft 200, and the second end of the second rotating part 205 is provided with the second guide part 2051.
[0067] The inner side wall of the first guide part 2041 and the second guide part 2051 is in the shape of a circular arc. The first guide part 2041 is arranged outside the first rotation connecting part 2011, and the second guide part 2051 is arranged outside the second rotation connecting part 2021. When the first rotating part 204 and the second rotating part 205 rotate around the rotating shaft 200, the first rotation connecting part 2011 rotates inside the first guide part 2041, and the second rotation connecting part rotates inside the second guide part 2051.
[0068] Thus, arranging the first guide part 2041 at the end of the first rotating part 204 away from the rotating shaft 200 can avoid interference with the rotation of the first rotating part 204, and arranging the second guide part 2051 at the end of the second rotating part 205 away from the rotating shaft 200 can avoid interference with the rotation of the second rotating part 205.
[0069] In addition, next referring to Figure 4 The first rotating part 204 further comprises a third guide part 2042, and the second rotating part 205 further comprises a fourth guide part 2052.
[0070] The first rotating member 204 and the second rotating member 205 respectively comprise opposite first ends and second ends, the first end of the first rotating member 204 is rotationally connected with the rotating shaft 200, and the second end of the first rotating member 204 is further provided with the third guide member 2042; the first end of the second rotating member 205 is rotationally connected with the rotating shaft 200, and the second end of the second rotating member 205 is further provided with the fourth guide member 2052.
[0071] The outer side wall of the third guide member 2042 and the fourth guide member 2052 is in the shape of a circular arc, the third guide member 2042 is arranged on the inner side of the first rotating connection part 2011, and the outer shape thereof matches the inner circular arc of the first rotating connection part 2011.
[0072] The fourth guide member 2052 is arranged on the inner side of the second rotating connection part 2021, and the outer shape thereof matches the inner circular arc of the second rotating connection part 2021.
[0073] When the first rotating member 204 and the second rotating member 205 rotate around the rotating shaft 200, the first rotating connection part 2011 rotates around the third guide member 2042, and the second rotating connection part 2021 rotates around the fourth guide member 2052.
[0074] The first guide member 2041 and the third guide member 2042 form a first arc-shaped groove 2040, the second guide member 2042 and the fourth guide member 2052 form a second arc-shaped groove 2050, the first rotating connection part 2011 is located in the first arc-shaped groove 2040, and the second rotating connection part 2021 is located in the second arc-shaped groove 2050.
[0075] The outer shape of the first arc-shaped groove 2040 matches that of the first rotating connection part 2011, and the outer shape of the second arc-shaped groove 2050 matches that of the second rotating connection part 2050.
[0076] When the first rotating member 204 and the second rotating member 205 rotate around the rotating shaft 200, the first rotating connection part 2011 slides in the first arc-shaped groove 2040 along the first arc-shaped groove 2040, and the second rotating connection part 2021 slides in the second arc-shaped groove 2050 along the second arc-shaped groove 2050.
[0077] In this way, the first rotating connection part 2011 is located in the first arc-shaped groove 2040, and the second rotating connection part 2021 is located in the second arc-shaped groove 2050, so as to protect the first rotating connection part 2011 and the second rotating connection part 2021.
[0078] In the above embodiment, even if the first support component 201 and the second support component 202 can be attached to the flexible screen 10, in the process of rotating the flexible screen 10 from flat to folded, sufficient avoiding space is still provided for the first support component 201 and the second support component 202, so that the flexible screen 10 has space to bend downward, avoiding bending upward and causing reverse arching. This is a necessary condition for the flexible screen 10 not to arch reversely.
[0079] Secondly, the first support component 201 and the second support component 202 cannot avoid too slowly or too quickly, otherwise the flexible screen 10 between the first support component 201 and the second support component 202 will arch or be pulled.
[0080] As shown in Figure 5 , too slow avoidance of the first support component 201 and the second support component 202 will cause the flexible screen 10 to arch.
[0081] As shown in Figure 6 , too fast avoidance of the first support component 201 and the second support component 202 will cause the flexible screen 10 to be pulled.
[0082] Therefore, the above rotating mechanism is further improved in the embodiments of the present application, so that the avoidance speed of the first support component 201 and the second support component 202 is adjustable.
[0083] As shown in Figure 7 , Figure 8 , Figure 9 , the rotating mechanism further comprises: a first connecting rod shaft 206 and a second connecting rod shaft 207, the first connecting rod shaft 206 and the second connecting rod shaft 207 respectively comprising: opposite first and second ends, the first end of the first connecting rod shaft 206 being rotationally connected with the first rotating shaft 2001 of the rotating shaft 200, the second end of the first connecting rod shaft 206 being provided with a first sliding pin 2061, the first end of the second connecting rod shaft 207 being rotationally connected with the second rotating shaft 2002 of the rotating shaft 200, the second end of the second connecting rod shaft 207 being provided with a second sliding pin 2071, the first support component 201 being provided with a 2012, the second support component 202 being provided with a second sliding groove 2022, when the first rotating part 204 and the second rotating part 205 rotate around the rotating shaft 200, the first sliding pin 2061 slides in the 2012, and the second sliding pin 2071 slides in the second sliding groove 2022. Thus, by providing the first connecting rod shaft 206 and the second connecting rod shaft 207, the rotating speed of the first support component 201 and the second support component 202 can be controlled, avoiding the first support component 201 and the second support component 202 rotating too fast or too slow to pull the flexible screen, and further avoiding the flexible screen arching.
[0084] Next, with reference to Figure 7 , Figure 8 ,Figure 9 The first connecting rod shaft 206 and the second connecting rod shaft 207 further comprise a third end; wherein the first rotating member 204 is provided with a first track 2043 adapted to the third end of the first connecting rod shaft 206, and the second rotating member 205 is provided with a second track 2053 adapted to the third end of the second connecting rod shaft 207; when the first rotating member 204 and the second rotating member 205 rotate around the rotating shaft 200, the third end of the first connecting rod shaft 206 slides in the first track 2043, and the third end of the second connecting rod shaft 207 slides in the second track 2053.
[0085] Thus, the first connecting rod shaft 206 and the second connecting rod shaft 207 are respectively inserted into the tracks of the first rotating member 204 and the second rotating member 205, and the rotational axis of the first rotating member 204 and the second rotating member 205 is different from the rotational axis of the first connecting rod shaft 206 and the second connecting rod shaft 207.
[0086] As shown in Figure 9 , the first rotating member 204 and the first connecting rod shaft 206 form a crank slider mechanism, and the second rotating member 205 and the second connecting rod shaft 207 form a crank slider mechanism.
[0087] Through the rotation of the first rotating member 204 and the second rotating member 205, the first connecting rod shaft 206 and the second connecting rod shaft 207 can be rotated, so that the speed of the support member and the rotating member is adapted, avoiding the first support member 201 and the second support member 202 rotating too fast or too slow to pull the flexible screen, further avoiding the flexible screen from arching.
[0088] The first connecting rod shaft 206 and the second connecting rod shaft 207 are Y-shaped structures. Thus, it is convenient to connect with the rotating shaft 200, the rotating member and the support member to form a crank slider mechanism.
[0089] The specific structure of the rotating shaft 200 is not limited in the embodiments of the present application.
[0090] Please refer to Figure 4 , Figure 7 , Figure 8 The rotating shaft 200 comprises a first rotating shaft 2001 and a second rotating shaft 2002, a third rotating shaft 2003 and a fourth rotating shaft 2004, a third support member 203 and a guide outer shaft 2005.
[0091] The third support member 203 and the guide outer shaft 2005 jointly enclose a cavity.
[0092] The first rotating shaft 2001 and the second rotating shaft 2002, the third rotating shaft 2003 and the fourth rotating shaft 2004 are located in a cavity surrounded by the third supporting part 203 and the guide outer shaft 2005, and the first rotating shaft 2001 and the second rotating shaft 2002, the third rotating shaft 2003 and the fourth rotating shaft 2004 are arranged side by side, for example.
[0093] The guide outer shaft 2005 covers the third rotating shaft and the fourth rotating shaft; wherein the length of the third rotating shaft 2003 and the fourth rotating shaft 2004 is less than the length of the guide outer shaft 2005, the second end of the length direction of the guide outer shaft 2005 extends along the length direction relative to the first end of the length direction of the guide outer shaft, and the third rotating shaft 2003 and the fourth rotating shaft 2004 are arranged between the first end of the length direction of the guide outer shaft 2005 and the second end of the length direction of the guide outer shaft 2005.
[0094] Thus, the third rotating shaft and the fourth rotating shaft are arranged in the guide outer shaft 2005, which can protect the third rotating shaft and the fourth rotating shaft.
[0095] The outer side of the third rotating shaft 2003 and the fourth rotating shaft 2004 and the inner side of the guide outer shaft 2005 form a slide.
[0096] The first rotating part 2044 is arranged on the first rotating member 204, and the second rotating part 2054 is arranged on the second rotating member 205, and the first rotating part 2044 and the second rotating part 2054 are located in the slide.
[0097] When the first rotating member 204 and the second rotating member 205 rotate around the rotating shaft, the first rotating part 2044 rotates around the third rotating shaft 2003 in the slide, and the second rotating part 2054 rotates around the fourth rotating shaft 2004 in the slide. Thus, the first rotating member can rotate around the third rotating shaft, and the second rotating member can rotate around the fourth rotating shaft.
[0098] The first connecting rod shaft 206 is connected with the first rotating shaft 2001, and the second connecting rod shaft 207 is connected with the second rotating shaft 2002.
[0099] It can be understood that when the first connecting rod shaft 206 and the second connecting rod shaft 207 rotate out of sync, for example, when the first rotating member 204 rotates and the second rotating member 205 does not move, the pulling force of the first rotating member 204 and the second rotating member 205 on the flexible screen is different, which is easy to make the flexible screen deviate to one side, affecting the stability of the connection between the flexible screen and the rotating mechanism.
[0100] In some embodiments of the present application, the first rotating shaft 2001 and the third rotating shaft 2003, the third rotating shaft 2003 and the fourth rotating shaft 2004, and the fourth rotating shaft 2004 and the second rotating shaft 2002 are connected through the transmission structure.
[0101] When the first connecting rod shaft drives the first rotating shaft 2001 to rotate, the transmission structure drives the second rotating shaft 2002 to rotate, and the second connecting rod shaft rotates synchronously.
[0102] Or, when the second connecting rod shaft drives the second rotating shaft 2002 to rotate, the transmission structure drives the first rotating shaft 2001 to rotate, and the first connecting rod shaft rotates synchronously.
[0103] In some embodiments of the present application, the transmission mechanism comprises:
[0104] a first gear sleeved on the first rotating shaft 2001, a third gear sleeved on the third rotating shaft 2003, a fourth gear sleeved on the fourth rotating shaft 2004, and a second gear sleeved on the second rotating shaft 2002.
[0105] The first gear and the third gear are engaged, the third gear and the fourth gear are engaged, and the fourth gear and the second gear are engaged.
[0106] Thus, the synchronous rotation of the first rotating shaft 2001, the third rotating shaft 2003, the fourth rotating shaft 2004, and the second rotating shaft 2002 is realized.
[0107] The working process of the rotating mechanism will be described below taking the first connecting rod shaft as an example. When the first connecting rod shaft 206 rotates, the first gear rotates around the first rotating shaft 2001, and at the same time, through the meshing effect of the gears, the movement and power of the first gear can be transmitted to the third gear, the fourth gear, and the second gear in turn, so that the second gear obtains the rotation speed and torque, and then drives the first connecting rod shaft 206 to rotate with the rotation of the second gear. Thus, the synchronous movement of the first connecting rod shaft 206 and the second connecting rod shaft 207 is realized, and the stability of the connection between the flexible screen and the rotating mechanism is improved.
[0108] The rotating mechanism provided by the embodiments of the present application can transmit torque for the unfolding and folding of the rotating mechanism through the meshing effect of the gears, realize the synchronous movement of the first connecting rod shaft 206 and the second connecting rod shaft 207, and then realize the synchronization of the flexible screens on both sides of the rotating shaft 200.
[0109] The above merely provides the specific implementation of the present application, but the protection scope of the present application is not limited to this. Any change or replacement within the technical scope disclosed by the present application should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
