技术领域technical field

本公开涉及电子设备领域，具体地，涉及一种柔性屏用折叠装置及移动终端。The present disclosure relates to the field of electronic equipment, and in particular, to a folding device for a flexible screen and a mobile terminal.

背景技术Background technique

随着电子设备技术的日趋发展，用户对具有大尺寸且易于携带的电子设备的需求越来越高，因此，具有折叠式柔性屏的电子设备得到广泛的关注。折叠式柔性屏在与电子设备的壳体装配时，为保证能够在折叠与展开状态之间切换，柔性屏的弯折部通常未与壳体固定连接。当折叠式柔性屏在折叠过程中，弯折部会出现向外凸出折叠及向内凹设折叠两种可能的运动状态。With the development of electronic device technology, users have higher and higher demands for electronic devices with large size and easy portability. Therefore, electronic devices with foldable flexible screens have received extensive attention. When the foldable flexible screen is assembled with the casing of the electronic device, in order to ensure that it can be switched between the folded and unfolded states, the bent portion of the flexible screen is usually not fixedly connected to the casing. When the foldable flexible screen is folded, there are two possible motion states of the folded part, the outwardly protruding and folded, and the inwardly concave and folded.

对于向内凹设折叠的折叠式柔性屏(即柔性屏的两个显示面可贴合折叠于壳体内)，在被折叠的状态下，柔性屏的中央部将会形成具有预定的曲率的变形部。电子设备的壳体在柔性屏由折叠到展开状态时需要进行适当的变形，以适应柔性屏的变形部形状的改变，否则柔性屏的变形部有可能无法被展平。For a foldable flexible screen that is folded concavely inward (that is, the two display surfaces of the flexible screen can be attached and folded in the casing), in the folded state, the central part of the flexible screen will be deformed with a predetermined curvature Department. The housing of the electronic device needs to be properly deformed when the flexible screen is folded to the unfolded state to adapt to the change of the shape of the deformed portion of the flexible screen, otherwise the deformed portion of the flexible screen may not be able to be flattened.

The thickness refers to the dimension perpendicular to the height direction of the flexible screen 201 when the folding device 100 for a flexible screen is applied to the mobile terminal 200 . In addition, the terms "first", "second" and the like used in the embodiments of the present disclosure are used to distinguish one element from another element, and have no order and importance.

在本公开中为了更好地支撑柔性屏201，如图1-19所示，提供了一种柔性屏用折叠装置100。该柔性屏用折叠装置100包括两个承载件10以及连接在两个承载件10之间的转动连接机构20。两个承载件10用于共同承载柔性屏201，两个承载件10通过转动连接机构20相铰接并且两个承载件10分别与转动连接机构20滑动连接，转动连接机构20包括弹屏滑动结构60，弹屏滑动结构60用于在柔性屏用折叠装置100展开时持续施加力以使两个承载件10相互远离的。In order to better support the flexible screen 201 in the present disclosure, as shown in FIGS. 1-19 , a folding device 100 for a flexible screen is provided. The folding device 100 for a flexible screen includes two carriers 10 and a rotational connection mechanism 20 connected between the two carriers 10 . The two bearing members 10 are used to jointly carry the flexible screen 201 , the two bearing members 10 are hingedly connected by the rotating connection mechanism 20 and the two bearing members 10 are respectively slidably connected with the rotating connecting mechanism 20 , and the rotating connecting mechanism 20 includes a pop-up screen sliding structure 60 . , the pop-up screen sliding structure 60 is used for continuously exerting force to keep the two carriers 10 away from each other when the folding device 100 for a flexible screen is unfolded.

通过上述技术方案，由于设置有弹屏滑动结构60，当柔性屏用折叠装置100展开时，在弹屏滑动结构60的作用下，两个承载件10之间始终能够具有相互远离的作用力，从而使得位于两个承载件10上的柔性屏201能够被绷紧，即使在外力的作用下，柔性屏201也不容易产生折弯，而且使柔性屏201能够更加紧密地贴合在承载件10上，使得承载件10对柔性屏201的支撑更加稳固，柔性屏201的平面度更高。与此同时，柔性屏201由折叠到展开状态时，在弹屏滑动结构60的作用下能够使柔性屏201中部的变形部2011被展开并绷紧，从而使柔性屏201始终保持于平滑的状态，避免了对柔性屏201的挤压或拉扯，从而能够有效减少在展开和折叠过程中可能对柔性屏201的产生的损伤，提高了柔性屏201的使用寿命。Through the above technical solution, since the pop-up screen sliding structure 60 is provided, when the flexible screen folding device 100 is unfolded, under the action of the pop-screen sliding structure 60, the two carriers 10 can always have a force away from each other.

在本公开中，对于具体如何设置弹屏滑动结构60不作限制，只要能够向承载件10上施加作用力使得两个承载件10之间互相远离即可。在本申请的一种实施方式中，如图8-10和图16所示，转动连接机构20还包括两个转动件40，两个转动件40铰接，两个承载件10分别与两个转动件40一一对应地滑动连接，其中至少一个承载件10和相应的转动件40之间连接有弹屏滑动结构60。In the present disclosure, there is no limitation on how to set the pop-up screen sliding structure 60, as long as a force can be applied to the carrier 10 so that the two carriers 10 are separated from each other. In an embodiment of the present application, as shown in FIGS. 8-10 and 16 , the rotating connection mechanism 20 further includes two rotating members 40 , the two rotating members 40 are hinged, and the two bearing members 10 are respectively connected with the two rotating members 40 . The parts 40 are slidably connected in one-to-one correspondence, wherein at least one of the bearing parts 10 and the corresponding rotating part 40 is connected with a pop-up screen sliding structure 60 .

柔性屏用折叠装置100展开时，两个转动件40之间相对转动，承载件10相对于转动件40滑动，由于承载件10与转动件40之间设置有弹屏滑动结构60，在弹屏滑动结构60的作用下，至少一个承载件10具有远离另一个承载件10的趋势，在此作用力下，使得位于两个承载件10上的柔性屏201能够被绷紧，使柔性屏201能够更加紧密地贴合在承载件10上，使得承载件10对柔性屏201的支撑更加稳固。在本公开的一种实施方式中，转动连接机构20包括两个弹屏滑动结构60，两个承载件10及其对应的转动件40之间均设置有上述的弹屏滑动结构60。两个弹屏滑动结构60分别作用于对应的承载件10上，使得两个承载件10承受相互远离的作用力，具有相互远离的趋势。When the folding device 100 for a flexible screen is unfolded, the two rotating members 40 rotate relative to each other, and the bearing member 10 slides relative to the rotating member 40 . Under the action of the sliding structure 60, at least one carrier 10 tends to move away from the other carrier 10. Under this force, the flexible screens 201 located on the two carriers 10 can be stretched, so that the flexible screens 201 can be stretched.

The two pop-up screen sliding structures 60 act on the corresponding bearing members 10 respectively, so that the two bearing members 10 are subjected to a force that moves away from each other and have a tendency to move away from each other.

在本公开中，对于弹屏滑动结构60具体采用何种方式向承载件10施加力不作限制，可根据需要设置。在本申请的一种实施方式中，图7-10和图16所示，弹屏滑动结构60包括滑动件61和施力件62，滑动件61的一部分与承载件10固定连接，滑动件61的另一部分与转动件40滑动连接，施力件62设置于滑动件61和转动件40之间以向滑动件61施加力，施力件62向滑动件61施加的力使得两个所述滑动件61之间相互远离。In the present disclosure, there is no limitation on how the pop-up screen sliding structure 60 applies force to the carrier 10 , and can be set as required.

施力件62向滑动件61施加作用力，使得两个滑动件61之间具有相互远离的作用力，从而使得与滑动件61固定连接的承载件10之间具有相互远离的趋势，从而将固定在承载件10上的柔性屏201绷紧。The force-applying member 62 exerts a force on the sliding member 61, so that the two sliding members 61 have a force that moves away from each other, so that the bearing members 10 fixedly connected to the sliding member 61 tend to move away from each other, so that the fixed The flexible screen 201 on the carrier 10 is stretched.

在本公开的一种实施方式中，如图10和图16所示，施力件62构造为第一弹性件，施力件62的两端分别与滑动件61和转动件40抵接，以向其中一个滑动件61施加远离另一个滑动件61的弹性力。施力件62可以是压簧，也可以是普通弹簧、弹片或者其他弹性机构。施力件62被压缩地设置于滑动件61和转动件40之间。In an embodiment of the present disclosure, as shown in FIG. 10 and FIG. 16 , the force applying member 62 is configured as a first elastic member, and both ends of the force applying member 62 are in contact with the sliding member 61 and the rotating member 40 respectively, so as to An elastic force is applied to one of the sliders 61 away from the other slider 61 . The force-applying member 62 may be a compression spring, or a common spring, an elastic sheet or other elastic mechanisms.

为了能够限制承载件10相对于转动件40滑动的最大位移，在本公开中的一种实施方式中，如图10和图16所示，弹屏滑动结构60还包括限位件64，滑动件61上设置有定位孔613，转动件40上设置有与定位孔613相对应的限位槽42，限位槽42沿滑动件61滑动的方向延伸，限位件64与滑动件61传动连接以与滑动件61同步滑动，限位件64穿过定位孔613且***限位槽42内，以在限位槽42内滑动。根据本申请的一个实施方式，限位件64可采用铆接的方式***滑动件61的孔内，从而使得限位件62与滑动件61固定连接。In order to limit the maximum sliding displacement of the bearing member 10 relative to the rotating member 40 , in an embodiment of the present disclosure, as shown in FIGS. 10 and 16 , the pop-up screen sliding structure 60 further includes a limiting member 64 . 61 is provided with a positioning hole 613, the rotating member 40 is provided with a limit slot 42 corresponding to the positioning hole 613, the limit slot 42 extends along the sliding direction of the sliding member 61, and the limit member 64 is connected with the sliding member 61 to drive Synchronously sliding with the sliding member 61 , the limiting member 64 passes through the positioning hole 613 and is inserted into the limiting groove 42 to slide in the limiting groove 42 .

当柔性屏用折叠装置100折叠或展开时，承载件10带动滑动件61相对于转动件40滑动，由于限位件64与滑动件61传动连接，滑动件61带动限位件64在限位槽42内滑动，当限位件64抵靠在限位槽42的侧壁时，限位件64无法继续相对于转动件40滑动，使得滑动件61也无法继续相对于转动件40滑动，从而能够限制承载件10相对于转动件40滑动的最大位移量，因此能够防止因为承载件10滑动过大对柔性屏201造成过度拉扯而损伤柔性屏201。When the folding device 100 for a flexible screen is folded or unfolded, the carrier 10 drives the sliding member 61 to slide relative to the rotating member 40. Since the limiting member 64 is connected to the sliding member 61 in a driving manner, the sliding member 61 drives the limiting member 64 in the limiting groove. 42, when the limiting member 64 abuts against the side wall of the limiting groove 42, the limiting member 64 cannot continue to slide relative to the rotating member 40, so that the sliding member 61 cannot continue to slide relative to the rotating member 40, so that the The maximum displacement of the bearing member 10 relative to the rotating member 40 is limited, so that the flexible screen 201 can be prevented from being damaged due to excessive pulling on the flexible screen 201 due to excessive sliding of the bearing member 10 .

When in the second motion state, the second surface 813 and the fourth surface 822 are in driving engagement, the reset element 83 releases the elastic potential energy, and the driven cam 82 pushes the driving cam 81 to continue to rotate. When transitioning between the first motion state and the second motion state, the first transition surface 814 and the second transition surface 823 are in contact. The external force needs to rotate the carrier 10 and lasts at least until the first transition surface 814 and the first transition surface 814 cooperate, so that the second surface 813 can cooperate with the fourth surface 822 and the carrier 10 can continue to rotate.

在其他实施方式中，可以理解的是，可设置一组辅助转动组件80，通过该辅助转动组件80带动其中一个承载件10转动，使得该承载件10相对于另一个承载件10转动，依然能够实现半自动展开或折叠柔性屏201。In other embodiments, it can be understood that a set of auxiliary rotating components 80 may be provided, and one of the bearing members 10 is driven to rotate by the auxiliary rotating components 80, so that the bearing member 10 can rotate relative to the other bearing member 10, and still be able to rotate. The flexible screen 201 can be unfolded or folded semi-automatically.

为了能够对展开状态的柔性屏201进行更加全面的支撑，根据本申请的一个实施例，如图3所示，转动连接机构20还包括铰接座30和两个滑动支撑板50，滑动支撑板50沿承载件10的转动轴线的方向延伸。其中一个滑动支撑板50设置于其中一个承载件10与相应的铰接座30之间，另一个滑动支撑板50设置于另一个承载件10与相应的铰接座30之间，从而将承载件10与铰接座30之间的空隙填满。滑动支撑板50与铰接座30铰接且与相应的承载件10滑动连接，以使柔性屏用折叠装置100展开时，两个滑动支撑板50、两个承载件10的上表面以及铰接座30的上表面位于同一平面以共同支撑柔性屏201，参照图5-6和图18。“上表面”指的是靠近且面向柔性屏201一侧的表面。In order to more comprehensively support the flexible screen 201 in the unfolded state, according to an embodiment of the present application, as shown in FIG. It extends in the direction of the axis of rotation of the carrier 10 . One of the sliding support plates 50 is arranged between one of the bearing members 10 and the corresponding hinge seat 30 , and the other sliding support plate 50 is arranged between the other bearing member 10 and the corresponding hinge seat 30 , thereby connecting the bearing member 10 to the corresponding hinge seat 30 . The gaps between the hinge seats 30 are filled. The sliding support plate 50 is hinged with the hinge base 30 and is slidably connected with the corresponding carrier 10 , so that when the flexible screen folding device 100 is unfolded, the two sliding support plates 50 , the upper surfaces of the two carriers 10 and the hinge base 30 . The upper surfaces are on the same plane to jointly support the flexible screen 201 , refer to FIGS. 5-6 and 18 . The "upper surface" refers to the surface close to and facing the side of the flexible screen 201 .

当柔性屏用折叠装置100展开时承载件10带动滑动支撑板50运动，使得两个滑动支撑板50展开，此时两个滑动支撑板50、两个承载件10的上表面以及铰接座30的上表面均位于同一平面，从而共同支撑处于展开状态中的柔性屏201，使得对柔性屏201的支撑面积更大，柔性屏201不会容易出现凹陷损坏。When the folding device 100 for a flexible screen is unfolded, the carrier 10 drives the sliding support plate 50 to move, so that the two sliding support plates 50 are unfolded. The upper surfaces are all on the same plane, so as to jointly support the flexible screen 201 in the unfolded state, so that the support area for the flexible screen 201 is larger, and the flexible screen 201 is not prone to dent damage.

根据本申请的一个实施例，如图3所示，滑动支撑板50设置有铰接部51和导向部52，铰接部51设置于滑动支撑板50靠近铰接座30的一侧，铰接部51与铰接座30铰接，如图4和图17所示，承载件10靠近铰接座30的一侧设置有导向滑槽11，导向部52与导向滑槽11配合，导向滑槽11大致呈Z字型结构，导向滑槽11的形状类似于Z字型结构，不一定呈标准的Z字型结构，比如可为由弧形槽段拼接形成的类似于Z字型结构的结构。According to an embodiment of the present application, as shown in FIG. 3 , the sliding support plate 50 is provided with a hinge portion 51 and a guide portion 52 , and the hinge portion 51 is provided on the side of the sliding support plate 50 close to the hinge seat 30 . The seat 30 is hinged. As shown in FIG. 4 and FIG. 17 , a guide chute 11 is provided on the side of the bearing member 10 close to the hinge seat 30 , the guide portion 52 is matched with the guide chute 11 , and the guide chute 11 is roughly Z-shaped. , the shape of the guide chute 11 is similar to a zigzag structure, not necessarily a standard zigzag structure, for example, a structure similar to a zigzag structure formed by splicing arc-shaped groove segments.

柔性屏用折叠装置100折叠时，在承载件10的带动下，铰接部51相对于铰接座30转动，并且两个导向部52相对于承载件10沿导向滑槽11朝背离柔性屏201的方向滑动，通过滑动支撑板50的下降为容纳柔性屏201的变形部2011腾出了空间，从而使得两个滑动支撑板50与铰接座30的上表面共同围合成用于容纳柔性屏201的容纳空间53，参照图19，使得该容纳空间53正好可容纳柔性屏201的中间的变形部2011，因此通过设置滑动支撑板50既能够在展开时对柔性屏201进行支撑，又能够在折叠时容纳柔性屏201的变形部2011。When the folding device 100 for a flexible screen is folded, driven by the carrier 10, the hinge portion 51 rotates relative to the hinge base 30, and the two guide portions 52 are relative to the carrier 10 along the guide chute 11 toward the direction away from the flexible screen 201 Sliding, the lowering of the sliding support plate 50 makes room for the deformation portion 2011 of the flexible screen 201, so that the two sliding support plates 50 and the upper surface of the hinge base 30 together form an accommodation space for accommodating the flexible screen 201 53. Referring to FIG. 19, the accommodating space 53 can just accommodate the deformation part 2011 in the middle of the flexible screen 201. Therefore, the sliding support plate 50 can not only support the flexible screen 201 when unfolding, but also accommodate the flexible screen 201 when folded. Deformation part 2011 of screen 201.

滑动支撑板50本身仅有相对于铰接座30的转动，由于承载件10会相对于铰接座30转动并滑动，因此，滑动支撑板50相对于承载件10转动并滑动。The sliding support plate 50 itself only rotates relative to the hinge base 30 . Since the carrier 10 rotates and slides relative to the hinge base 30 , the sliding support plate 50 rotates and slides relative to the carrier 10 .

为了使两个承载件10之间能够同步运动，在本公开的一种实施方式中，如图10所示，每个转动件40均设置有转轴43，转动连接机构20还包括同步传动组件70，同步传动组件70传动连接于两个转轴43之间，以使两个转动件40同步转动，进而带动两个承载件10同步转动。In order to enable synchronous movement between the two carriers 10 , in an embodiment of the present disclosure, as shown in FIG. 10 , each rotating member 40 is provided with a rotating shaft 43 , and the rotating connecting mechanism 20 further includes a synchronous transmission assembly 70 , the synchronous transmission assembly 70 is driven and connected between the two rotating shafts 43 to make the two rotating members 40 rotate synchronously, thereby driving the two bearing members 10 to rotate synchronously.

在本公开中对于同步传动组件70具体采用何种传动机构不作限制，例如可采用带轮或链轮传动机构。根据本申请的一个实施例，如图8和图10所示，同步传动组件70构造成齿轮组。根据本申请的一个实施例，齿轮组包括第一齿轮71、第二齿轮72、第三齿轮73和第四齿轮74。第一齿轮71和第二齿轮72分别与两个转轴43一一对应地传动连接，第一齿轮71、第三齿轮73、第四齿轮74和第二齿轮72依次啮合传动，第三齿轮73和第四齿轮74设置在第一齿轮71和第二齿轮72背离柔性屏201的一侧，第一齿轮71包括第一圆周面部和与第三齿轮73啮合的第一齿牙部，第一圆周面部未设置齿牙且靠近柔性屏201设置，第二齿轮72包括第二圆周面部和与第四齿轮74啮合的第二齿牙部，第二圆周面部未设置齿牙且靠近柔性屏201设置。In the present disclosure, there is no limitation on the specific transmission mechanism used by the synchronous transmission assembly 70, for example, a pulley or sprocket transmission mechanism may be used. According to one embodiment of the present application, as shown in FIGS. 8 and 10 , the synchronous transmission assembly 70 is configured as a gear set. According to an embodiment of the present application, the gear set includes a first gear 71 , a second gear 72 , a third gear 73 and a fourth gear 74 . The first gear 71 and the second gear 72 are respectively connected with the two rotating shafts 43 in a one-to-one correspondence. The fourth gear 74 is disposed on the side of the first gear 71 and the second gear 72 facing away from the flexible screen 201 . The first gear 71 includes a first circumferential surface portion and a first tooth portion that meshes with the third gear 73 . The first circumferential surface portion The second gear 72 includes a second circumferential surface portion and a second teeth portion meshed with the fourth gear 74 , and the second circumferential surface portion is not provided with teeth and is provided close to the flexible screen 201 .

由于柔性屏用折叠装置100在打开和关闭时仅需使承载件10转动90°，因此，可使第一齿轮71和第二齿轮72的部分圆周上不设置齿牙，使得第一齿轮71和第二齿轮72的回转中心更加靠近柔性屏201，进而使得转动件40上的转轴43(即承载件10的转动轴线)能够更加靠近柔性屏201，从而使得柔性屏201在打开和折叠时的变形部2011的尺寸(垂直于转动轴向方向的尺寸)更小，以便折叠时柔性屏201的变形部2011能够容纳于容纳空间53中，与此同时，柔性屏201展开和折叠时，承载件10需要滑动的距离更小。当承载件10的转动轴线位于柔性屏201上时，柔性屏201在打开和折叠时承载件10不需要滑动。此外，由于第一齿轮71和第二齿轮72的部分圆周上不设置齿牙，这样能够减少第一齿轮71和第二齿轮72的在厚度方向上的尺寸，从而使得同步传动组件70在厚度方向占用的空间更小，具有该柔性屏用折叠装置100的移动终端200可以设计的更薄。Since the folding device 100 for a flexible screen only needs to rotate the carrier 10 by 90° when opening and closing, the first gear 71 and the second gear 72 may not be provided with teeth on part of the circumference, so that the first gear 71 and the second gear 72 are not provided with teeth. The rotation center of the second gear 72 is closer to the flexible screen 201, so that the rotating shaft 43 on the rotating member 40 (ie, the rotation axis of the carrier 10) can be closer to the flexible screen 201, so that the flexible screen 201 can be deformed when it is opened and folded. The size of the portion 2011 (the size perpendicular to the axial direction of rotation) is smaller, so that the deformed portion 2011 of the flexible screen 201 can be accommodated in the accommodating space 53 when folded. At the same time, when the flexible screen 201 is unfolded and folded, the carrier 10 The distance that needs to be swiped is smaller. When the rotation axis of the carrier 10 is located on the flexible screen 201, the carrier 10 does not need to slide when the flexible screen 201 is opened and folded. In addition, since teeth are not provided on part of the circumference of the first gear 71 and the second gear 72, the size of the first gear 71 and the second gear 72 in the thickness direction can be reduced, so that the synchronous transmission assembly 70 can be reduced in the thickness direction. The occupied space is smaller, and the mobile terminal 200 having the folding device 100 for a flexible screen can be designed to be thinner.
