一种转轴机构及可折叠移动终端A shaft mechanism and a foldable mobile terminal

技术领域technical field

本申请实施例涉及终端技术领域，尤其涉及一种转轴机构及可折叠移动终端。The embodiments of the present application relate to the technical field of terminals, and in particular to a hinge mechanism and a foldable mobile terminal.

背景技术Background technique

随着柔性屏技术的发展，柔性屏应用逐渐增多，可折叠移动终端即为柔性屏技术的一种应用。可折叠移动终端的柔性显示屏可以连续可折叠，图1为现有技术中的一种柔性屏的状态图，如图1中的(a)示出了柔性屏在展开状态时的状态图，图1中的(b)示出了柔性屏在折叠状态的状态图，其中，阴影部分为折弯部分。可折叠移动终端在由展开状态到折叠状态的过程中，柔性屏的折弯部分会受到来自可折叠移动终端的壳体的挤压力，并因此产生过度弯折变形，因此可能会造成柔性屏被挤压，例如，对比图1中的(a)和图1中的(b)可知，柔性屏折弯部分的外侧长度从L1到L3，两者等长；而内侧长度从L2需变化为L4，L4远小于L2，内侧长度变化量很大，这样将会对柔性屏产生挤压作用。反之，可折叠移动终端在由折叠状态到展开状态的过程中，壳体将会对柔性屏产生拉扯作用。With the development of flexible screen technology, flexible screen applications are gradually increasing, and foldable mobile terminals are an application of flexible screen technology. The flexible display screen of a foldable mobile terminal can be folded continuously. FIG. 1 is a state diagram of a flexible screen in the prior art, and (a) in FIG. 1 shows a state diagram of the flexible screen in an unfolded state. (b) in FIG. 1 shows a state diagram of the flexible screen in a folded state, wherein the shaded part is a bent part. When the foldable mobile terminal is from the unfolded state to the folded state, the bending part of the flexible screen will be squeezed from the shell of the foldable mobile terminal, and excessive bending deformation will occur, which may cause the flexible screen For example, comparing (a) in Figure 1 and (b) in Figure 1, it can be seen that the outer length of the flexible screen bending part is from L1 to L3, and both are equal in length; while the inner length needs to be changed from L2 to L4, L4 is much smaller than L2, and the inner length changes greatly, which will squeeze the flexible screen. Conversely, when the foldable mobile terminal changes from the folded state to the unfolded state, the housing will pull the flexible screen.

图2为现有技术中的一种可折叠移动终端的状态图，图2中的(a)为展开状态图，图2中的(b)为折叠状态图。如图2中的(a)所示，两个壳体之间通过一个转轴结构连接，柔性屏设置在两个壳体与转轴结构的同一表面，柔性屏与壳体之间有较大的间距。可折叠移动终端在由展开状态至折叠状态的过程中，柔性屏的中间区域会跟随转轴结构产生拱起的弯曲变形，柔性屏会相对壳体滑动，这样可避免柔性屏过度弯折变形而不会挤压柔性屏。然而，在使用过程中，柔性屏与壳体之间会相对滑动，这样会增加柔性屏的损坏风险，对柔性屏的要求较高。如图2中的(b)所示，在折叠状态的柔性屏从侧面看类似于球棒状，可折叠移动终端的厚度差异很大。折叠状态时两侧壳体之间有一个很大的间隙，容易掉入细长条的物体而造成柔性屏的损伤。Fig. 2 is a state diagram of a foldable mobile terminal in the prior art, (a) in Fig. 2 is an unfolded state diagram, and Fig. 2 (b) is a folded state diagram. As shown in (a) in Figure 2, the two housings are connected by a rotating shaft structure, the flexible screen is arranged on the same surface of the two housings and the rotating shaft structure, and there is a large distance between the flexible screen and the housing . When the foldable mobile terminal is from the unfolded state to the folded state, the middle area of the flexible screen will follow the shaft structure to produce an arched bending deformation, and the flexible screen will slide relative to the housing, which can avoid excessive bending and deformation of the flexible screen Will squeeze the flexible screen. However, during use, the flexible screen and the housing will slide relative to each other, which will increase the risk of damage to the flexible screen, and has higher requirements on the flexible screen. As shown in (b) of FIG. 2 , the flexible screen in the folded state looks like a bat from the side, and the thickness of the foldable mobile terminal varies greatly. In the folded state, there is a large gap between the shells on both sides, and it is easy to fall into slender objects and cause damage to the flexible screen.

如何实现可折叠移动终端展开及折叠过程中不拉扯和挤压柔性屏，并且实现可折叠移动转动在折叠状态时厚度差异较小且无较大的间隙，是亟需解决的技术问题。How to realize that the foldable mobile terminal does not pull and squeeze the flexible screen during the unfolding and folding process, and realize that the thickness difference is small and there is no large gap when the foldable mobile terminal is in the folded state, which is a technical problem that needs to be solved urgently.

本申请实施例涉及一种转轴机构及可折叠移动终端，以实现可折叠移动终端展开及折叠过程中不拉扯和挤压柔性屏，并且实现可折叠移动转动在折叠状态时厚度差异较小且无较大的间隙。The embodiment of the present application relates to a hinge mechanism and a foldable mobile terminal, so as to realize that the foldable mobile terminal does not pull and squeeze the flexible screen during the unfolding and folding process, and realize that the thickness difference of the foldable mobile terminal is small and no Larger gaps.

为了解决上述技术问题，本申请实施例提供如下技术方案：In order to solve the above technical problems, the embodiments of the present application provide the following technical solutions:

The rotating shaft mechanism includes: a main shaft, rotating assemblies arranged in pairs, and support plates arranged on both sides of the main shaft. Each pair of rotating assemblies is arranged on both sides of the main shaft in a direction perpendicular to the axis of the main shaft. Each rotating assembly includes one or more swing arms connected with the inner wall of the main shaft by pins. A pair of support plates are arranged on both sides of the main shaft, and the support plates on the same side of the main shaft are arranged correspondingly to the rotating assembly. Wherein, one end of each support plate is rotatably connected with the main shaft, and the opposite end is slidably connected with the rotating assembly and can rotate relatively. Alternatively, one end of each support plate is slidably connected to the main shaft and can rotate relatively, and the opposite end is rotatably connected to the rotating assembly. When the rotating assemblies located on both sides of the main shaft are relatively rotated to the first position, the rotating assembly drives the corresponding supporting plate to rotate to the second position, and an accommodation space is formed between the supporting plates located on both sides of the main shaft and the main shaft.

其中，第一位置是指在转轴机构完全折叠状态时转动组件所在位置，此时，主轴两侧的转动组件相互靠近，两侧的转动组件上与移动终端壳体固定的固定面大致平行。第二位置是指在转轴机构完全折叠状态时支撑板所在位置，此时，主轴两侧的支撑板相互靠近，两侧的支撑板在靠近主轴位置的间距比较宽，在远离主轴位置的间距比较窄。Wherein, the first position refers to the position of the rotating assembly when the rotating shaft mechanism is fully folded. At this time, the rotating assemblies on both sides of the main shaft are close to each other, and the rotating assemblies on both sides are roughly parallel to the fixed surface fixed to the mobile terminal housing. The second position refers to the position of the support plate when the rotating shaft mechanism is fully folded. At this time, the support plates on both sides of the main shaft are close to each other, and the distance between the support plates on both sides is relatively wide when it is close to the main shaft, and the distance between the support plates is relatively wide when it is far away from the main shaft. narrow.

本申请实施例提供的转轴机构，在主轴的两侧均布置有转动组件与支撑板，转动组件的摆臂与主轴的内壁之间销轴连接。支撑板连接于主轴和转动组件之间，这样在转动组件相对主轴转动时，转动组件将会带动支撑板相对主轴转动。其中，在主轴两侧的转动组件转动至第一位置时，转动组件将会带动两侧的支撑板转动至第二位置，两侧的支撑板在靠近主轴位置的间距比较宽，在远离主轴位置的间距比较窄，两侧支撑板之间上部间距小而下部间距大，形成一个内凹的容纳空间，以容纳柔性屏部分区域。在主轴两侧的转动组件转动展开时，转动组件带动对应的支撑板转动展开，支撑板可支撑在转动组件上，主轴与支撑板可共同支撑柔性屏部分区域，支撑效果好。In the rotating shaft mechanism provided in the embodiment of the present application, a rotating assembly and a support plate are arranged on both sides of the main shaft, and the swing arm of the rotating assembly is connected with the inner wall of the main shaft by a pin. The supporting plate is connected between the main shaft and the rotating assembly, so that when the rotating assembly rotates relative to the main shaft, the rotating assembly will drive the supporting plate to rotate relative to the main shaft. Wherein, when the rotating assembly on both sides of the main shaft rotates to the first position, the rotating assembly will drive the support plates on both sides to rotate to the second position. The distance between the support plates on both sides is relatively narrow, and the distance between the upper part and the lower part of the support plates on both sides is small, forming a concave accommodation space to accommodate part of the flexible screen. When the rotating components on both sides of the main shaft rotate and expand, the rotating components drive the corresponding support plates to rotate and expand. The support plates can be supported on the rotating components. The main shaft and the support plates can jointly support a part of the flexible screen, and the supporting effect is good.

将上述转轴机构应用到可折叠移动终端上，也就是将转轴机构连接在两个壳体之间，位于主轴同一侧的转动组件固定到对应的壳体上。移动终端由展开状态至折叠状态的过程中，柔性屏的中间区域逐渐弯曲且截面形成水滴状，由于主轴两侧的支撑板与主轴之间形成的容纳空间可容纳该柔性屏的水滴状区域，这样就不会挤压柔性屏且不起拱。反之，在折叠状态至展开状态的过程中，也不会拉扯到柔性屏。在折叠与展开的过程中，柔性屏也不会相对壳体滑动，降低了柔性屏失效的风险，提高了柔性屏的可靠性。采用本申请实施例转轴机构的移动终端，主轴两侧的转动组件的摆臂与主轴的内壁之间销轴连接，采用双轴的方式实现两个壳体的连接，移动终端在折叠状态时的厚度差异较小，两个壳体之间无较大的间隙，降低细长条物体掉入间隙而造成柔性屏损伤的可能性。The above-mentioned rotating shaft mechanism is applied to the foldable mobile terminal, that is, the rotating shaft mechanism is connected between two housings, and the rotating components located on the same side of the main shaft are fixed to the corresponding housings. When the mobile terminal is from the unfolded state to the folded state, the middle area of the flexible screen is gradually bent and the cross-section forms a drop shape. Since the accommodation space formed between the support plates on both sides of the main shaft and the main shaft can accommodate the water drop-shaped area of the flexible screen, In this way, the flexible screen will not be squeezed and there will be no arching. Conversely, the flexible screen will not be pulled during the process from the folded state to the unfolded state. In the process of folding and unfolding, the flexible screen will not slide relative to the casing, which reduces the risk of failure of the flexible screen and improves the reliability of the flexible screen. In the mobile terminal adopting the rotating shaft mechanism of the embodiment of the present application, the swing arms of the rotating components on both sides of the main shaft are pinned to the inner wall of the main shaft, and the connection of the two housings is realized in a biaxial manner. When the mobile terminal is in the folded state, the The difference in thickness is small, and there is no large gap between the two shells, which reduces the possibility of damage to the flexible screen caused by slender objects falling into the gap.

The limiting component is arranged between the rotating component and the displacement component on the same side, and when the displacement component rotates relative to the main shaft, the limiting component is used to provide damping effect for the displacement component. The function of the displacement component is to produce a different rotational phase difference from that of the rotating component, that is, when the rotating component rotates to drive the displacement component to rotate, the rotation angles of the rotating component and the displacement component are different, so that the displacement component can produce a sliding displacement relative to the rotating component .

The extending direction of the first accommodating groove may be perpendicular to the extending direction of the second accommodating groove, and the extending direction of the first accommodating groove may also be perpendicular to the axis of the main shaft.

When the rotating assembly rotates relative to the main shaft, the link part moves along the extending direction of the first accommodating groove. Under the action of the elastic structural member, the damping member can move along the side wall of the connecting rod portion close to the second accommodating groove. Since the side wall of the connecting rod portion near the second accommodating groove has a limiting groove, the damping member will fall into the limiting groove under the elastic force of the elastic structural member during the movement, so as to prevent the damping member from continuing to move on the connecting rod. The upper part moves, so that the rotating assembly stops rotating, so that the casing of the mobile terminal can be reliably maintained at the corresponding rotating position. Wherein, the number of limiting grooves on the connecting rod part can be one or more. When the connecting rod part has multiple limiting grooves, the damping part and the elastic structural part can be used to realize the rotation of the rotating assembly in multiple positions. Reliable limit. Wherein, the damping element can be a ball or a sliding body. When the damping member is a ball, the ball can roll along the side wall of the connecting rod part close to the second accommodation groove, so the movement is more flexible. When the damping element is a sliding body, the sliding body can slide along the side wall of the connecting rod portion close to the second accommodating groove to provide better damping force. The sliding body can be provided with a limiting convex surface that matches the limiting groove. When the sliding body moves to the limiting groove, the limiting convex surface will slide into the limiting groove. Compared with the damping part using balls, The damping element adopts a sliding body with a limiting convex surface to provide greater damping force.

结合第一方面的第十六种可能的实现方式或第十七种可能的实现方式，在第一方面的第十八种可能的实现方式中，每个转动组件对应支撑一个位移组件；每个转动组件设置有一个第一容置槽，转动组件还包括设置于第二容置槽远离位移组件一端的挡板，弹性结构件的一端固定于该挡板。其中，弹性结构件可以但不限于为弹簧，当弹性结构件为弹簧时，为了实现对弹簧的限位，以使其在运动过程中不发生弯折，可以在挡板上设置限位支柱，从而使弹簧套设于限位支柱。在该弹簧靠近位移组件的一端还设置有连接板，连接板卡接于第二容置槽的槽壁，以使弹簧能够限位于第二容置槽。连接板上也可以设置限位支柱，并使弹簧套设于该限位支柱。此时，阻尼件与连接板相抵接，并可沿连接板的表面运动，这样可减小弹性结构件与阻尼件之间的摩擦，使阻尼件的运动更加灵活。With reference to the sixteenth possible implementation manner or the seventeenth possible implementation manner of the first aspect, in the eighteenth possible implementation manner of the first aspect, each rotating assembly supports a displacement assembly; each The rotating assembly is provided with a first accommodating groove, and the rotating assembly further includes a baffle arranged at an end of the second accommodating groove away from the displacement assembly, and one end of the elastic structural member is fixed to the baffle. Wherein, the elastic structural member can be but not limited to a spring. When the elastic structural member is a spring, in order to realize the limit of the spring so that it does not bend during the movement, a limit pillar can be set on the baffle. Thus, the spring is sleeved on the position-limiting pillar. A connecting plate is also provided at the end of the spring close to the displacement assembly, and the connecting plate is clamped to the groove wall of the second accommodating groove, so that the spring can be limited in the second accommodating groove. A limit post can also be arranged on the connecting plate, and the spring is sheathed on the limit post. At this time, the damping element abuts against the connecting plate and can move along the surface of the connecting plate, which can reduce the friction between the elastic structural member and the damping element and make the movement of the damping element more flexible.

结合第一方面的第十六种可能的实现方式或第十七种可能的实现方式，在第一方面的第十九种可能的实现方式中，一个转动组件设置有两个位移组件，两个位移组件共用一个限位组件。每个转动组件设置有两个用于容置位移组件的第一容置槽，位移组件能够一一对应的容置于第一容置槽。使弹性结构件的两端各设置一个阻尼件，并使每个阻尼件能够沿对应的位移组件的连杆部侧壁移动。采用该种设置方式可以有效的增加限位组件与连杆部之间的阻尼力，从而实现包含有该转动组件的可折叠移动终端的折叠状态的有效维持。另外，位于主轴同一侧的转动组件之间可通过加强杆连接，这样可以提高结构强度。With reference to the sixteenth possible implementation manner or the seventeenth possible implementation manner of the first aspect, in the nineteenth possible implementation manner of the first aspect, one rotating assembly is provided with two displacement assemblies, and two The displacement components share a limit component. Each rotating assembly is provided with two first accommodating grooves for accommodating the displacement assemblies, and the displacement assemblies can be accommodated in the first accommodating grooves one by one. A damper is provided at both ends of the elastic structural member, and each damper can move along the side wall of the connecting rod part of the corresponding displacement assembly. This arrangement can effectively increase the damping force between the limiting component and the connecting rod, so as to effectively maintain the folded state of the foldable mobile terminal including the rotating component. In addition, the rotating components on the same side of the main shaft can be connected by reinforcing rods, which can improve the structural strength.

结合第一方面的第十六种可能的实现方式至第十九种可能的实现方式中任一项，在第一方面的第二十种可能的实现方式中，每个第一容置槽的槽壁开设有导向槽，导向槽的延伸方向与第一容置槽的延伸方向相同，导向槽设置在第一容置槽远离第二容置槽的槽壁上。每个位移组件还包括设置于连杆部上且滑动装配在导向槽的滑动部。在位移组件的连杆部随转动组件转动的过程中，滑动部限位于导向槽，且可沿导向槽滑动，这样在转动组件转动的过程中，可避免位移组件脱离转动组件，从而有效的提高位移组件运动的可靠性。In combination with any of the sixteenth possible implementation manner to the nineteenth possible implementation manner of the first aspect, in the twentieth possible implementation manner of the first aspect, each of the first accommodating grooves The groove wall is provided with a guide groove, the extension direction of the guide groove is the same as that of the first accommodation groove, and the guide groove is arranged on the groove wall of the first accommodation groove away from the second accommodation groove. Each displacement assembly also includes a sliding part arranged on the connecting rod part and slidingly fitted in the guide groove. When the connecting rod part of the displacement assembly rotates with the rotation assembly, the sliding part is limited to the guide groove and can slide along the guide groove, so that during the rotation of the rotation assembly, the displacement assembly can be prevented from detaching from the rotation assembly, thereby effectively improving Reliability of movement of displacement components.

结合第一方面的第十六种可能的实现方式至第二十种可能的实现方式中任一项，在第一方面的第二十一种可能的实现方式中，每个位移组件的连杆部的第一端处固定设置齿轮部，连杆部与主轴之间的转动轴线与齿轮部的轴线重合；主轴设有成对布置且相啮合的同步齿轮，成对的同步齿轮与成对的阻尼组对应设置，同一对阻尼组中的每个位移组件的齿轮部与成对的同步齿轮一一对应地啮合。在其中一个转动组件相对主轴转动时，该转动组件上的位移组件相对主轴转动并相对转动组件滑动，转动组件上的齿轮部与其中一个同步齿轮啮合，另一个同步齿轮啮合转动，同一对阻尼组中的位移组件与转动组件对称布置，从而使另一侧的位移组件与转动组件跟随运动，即另一侧的转动组件也跟随折叠或展开，进而实现移动终端的同步折叠。其中，同一对阻尼组的位移组件中的齿轮部与成对的同步齿轮位于同一平面位置。将齿轮部相对主轴的转动轴线靠近主轴在宽度方向的边缘设置，这样同步齿轮可设置在主轴的内部，充分利用主轴宽度方向的空间，使得主轴宽度尺寸较小。在一个转动组件设置有两个位移组件时，两个位移组件均可配置齿轮部，主轴也配置更多对同步齿轮，齿轮部与同步齿轮啮合传动，这样可使主轴两侧的位移组件相对主轴的转动更顺畅，进而使主轴两侧的转动组件相对主轴转动更稳定可靠。In combination with any one of the sixteenth possible implementation manner to the twentieth possible implementation manner of the first aspect, in the twenty-first possible implementation manner of the first aspect, the connecting rod of each displacement component The gear part is fixedly arranged at the first end of the part, and the rotation axis between the connecting rod part and the main shaft coincides with the axis of the gear part; The damping groups are arranged correspondingly, and the gear part of each displacement assembly in the same pair of damping groups meshes with the pair of synchronous gears in a one-to-one correspondence. When one of the rotating components rotates relative to the main shaft, the displacement component on the rotating component rotates relative to the main shaft and slides relative to the rotating component. The gear part on the rotating component meshes with one of the synchronous gears, and the other synchronous gear meshes and rotates. The same pair of damping groups The displacement assembly and the rotation assembly are symmetrically arranged, so that the displacement assembly and the rotation assembly on the other side follow the movement, that is, the rotation assembly on the other side also follows the folding or unfolding, thereby realizing the synchronous folding of the mobile terminal. Wherein, the gear part in the displacement assembly of the same pair of damping groups is located on the same plane as the pair of synchronous gears. The rotation axis of the gear part relative to the main shaft is arranged close to the edge of the main shaft in the width direction, so that the synchronous gear can be arranged inside the main shaft, making full use of the space in the main shaft width direction, so that the width of the main shaft is smaller. When a rotating component is provided with two displacement components, both displacement components can be equipped with gear parts, and the main shaft is also equipped with more pairs of synchronous gears, and the gear parts are meshed with the synchronous gears for transmission, so that the displacement components on both sides of the main shaft can be aligned with the main shaft. The rotation of the shaft is smoother, so that the rotating components on both sides of the main shaft are more stable and reliable relative to the rotation of the main shaft.

第二方面，本申请实施例提供一种可折叠移动终端，包括第一方面至第一方面的第二十一种可能的实现方式中任一项所描述的转轴机构、第一壳体、第二壳体以及柔性屏，第一壳体与第二壳体分设于转轴机构的两侧，位于主轴其中一侧的转动组件固定于第一壳体，位于主轴另外一侧的转动组件固定于第二壳体，柔性屏的两端部分别固定于第一壳体与第二壳体，柔性屏的中间区域对应主轴与支撑板设置。In a second aspect, an embodiment of the present application provides a foldable mobile terminal, including the hinge mechanism described in any one of the twenty-first possible implementation manners from the first aspect to the first aspect, a first housing, and a first housing. Two housings and a flexible screen, the first housing and the second housing are separately arranged on both sides of the rotating shaft mechanism, the rotating assembly on one side of the main shaft is fixed on the first housing, and the rotating assembly on the other side of the main shaft is fixed on the second housing Two housings, the two ends of the flexible screen are respectively fixed to the first housing and the second housing, and the middle area of the flexible screen is arranged corresponding to the main shaft and the support plate.

本申请实施例提供的可折叠移动终端，将上述转轴机构应用到该可折叠移动终端，主轴两侧的转动组件分别固定到第一壳体与第二壳体，实现第一壳体与第二壳体的连接，并且柔性屏的两端部分别固定于第一壳体与第二壳体。在主轴的两侧均布置有转动组件与支撑板，转动组件的摆臂与主轴内壁之间销轴连接。支撑板连接于主轴和转动组件之间，这样在转动组件相对主轴转动时，转动组件将会带动支撑板相对主轴转动。其中，在主轴两侧的转动组件转动至第一位置时，转动组件将会带动两侧的支撑板转动至第二位置，两侧的支撑板在靠近主轴位置的间距比较宽，在远离主轴位置的间距比较窄，两侧支撑板之间上部间距小而下部间距大，形成一个内凹的容纳空间，以容纳柔性屏部分区域。在主轴两侧的转动组件转动展开时，转动组件带动对应的支撑板转动展开，支撑板可支撑在转动组件上，主轴与支撑板可共同支撑柔性屏部分区域，支撑效果好。In the foldable mobile terminal provided by the embodiment of the present application, the above-mentioned rotating shaft mechanism is applied to the foldable mobile terminal, and the rotating components on both sides of the main shaft are respectively fixed to the first casing and the second casing to realize the first casing and the second casing. The casing is connected, and the two ends of the flexible screen are respectively fixed to the first casing and the second casing. Rotating components and support plates are arranged on both sides of the main shaft, and the swing arm of the rotating component is connected with the inner wall of the main shaft by a pin shaft. The supporting plate is connected between the main shaft and the rotating assembly, so that when the rotating assembly rotates relative to the main shaft, the rotating assembly will drive the supporting plate to rotate relative to the main shaft. Wherein, when the rotating assembly on both sides of the main shaft rotates to the first position, the rotating assembly will drive the support plates on both sides to rotate to the second position. The distance between the support plates on both sides is relatively narrow, and the distance between the upper part and the lower part of the support plates on both sides is small, forming a concave accommodation space to accommodate part of the flexible screen. When the rotating components on both sides of the main shaft rotate and expand, the rotating components drive the corresponding support plates to rotate and expand. The support plates can be supported on the rotating components. The main shaft and the support plates can jointly support a part of the flexible screen, and the supporting effect is good.

移动终端由展开状态至折叠状态的过程中，柔性屏的中间区域逐渐弯曲且截面形成水滴状，由于位于主轴两侧的支撑板与主轴之间形成的容纳空间可容纳该柔性屏的水滴状区域，这样就不会挤压柔性屏且不起拱。反之，在折叠状态至展开状态的过程中，也不拉扯到柔性屏，柔性屏的中间区域逐渐展平，主轴与支撑板共同支撑柔性屏展平后的中间区域。在折叠与展开的过程中，柔性屏也不会相对壳体滑动，降低了柔性屏失效的风险，提高了柔性屏的可靠性。位于主轴两侧的转动组件的摆臂与主轴内壁之间销轴连接，采用双轴的方式实现两个壳体的连接，移动终端在折叠状态时的厚度差异较小，两个壳体之间无较大的间隙，降低细长条物体掉入间隙而造成柔性屏损伤的可能性。During the process of the mobile terminal from the unfolded state to the folded state, the middle area of the flexible screen is gradually bent and the cross-section forms a drop shape. Since the accommodation space formed between the support plates on both sides of the main shaft and the main shaft can accommodate the water drop-shaped area of the flexible screen , so that the flexible screen will not be squeezed and will not arch. Conversely, in the process from the folded state to the unfolded state, the flexible screen is not pulled, and the middle area of the flexible screen is gradually flattened, and the main shaft and the support plate jointly support the flattened middle area of the flexible screen. In the process of folding and unfolding, the flexible screen will not slide relative to the casing, which reduces the risk of failure of the flexible screen and improves the reliability of the flexible screen. The swing arm of the rotating assembly located on both sides of the main shaft is connected with the inner wall of the main shaft by a pin shaft, and the connection of the two housings is realized in a biaxial manner. The thickness difference of the mobile terminal in the folded state is small, and the difference between the two housings There is no large gap, which reduces the possibility of damage to the flexible screen caused by slender objects falling into the gap.

可折叠移动终端处于完全折叠状态时，从外部看该移动终端，只看到第一壳体与第二壳体之间连接有主轴，而看不到两个壳体的连接位置存在缺口的情况。相比于现有移动终端两个壳体之间采用单轴的连接方式，本申请实施例提供的转轴机构采用双轴连接，单个转动组件相对主轴的转角可以更小，这样单个转动组件与主轴之间连接位置的结构体积可以更小，移动终端在完全展开状态时，转轴机构并不会过多突出壳体。When the foldable mobile terminal is in a fully folded state, when looking at the mobile terminal from the outside, only the main shaft is connected between the first shell and the second shell, but there is no gap at the connecting position of the two shells . Compared with the single-axis connection between the two shells of the existing mobile terminal, the shaft mechanism provided by the embodiment of the present application adopts a double-axis connection, and the rotation angle of a single rotating component relative to the main shaft can be smaller, so that the single rotating component and the main shaft The structural volume of the connecting position can be smaller, and when the mobile terminal is in a fully unfolded state, the rotating shaft mechanism does not protrude too much from the housing.

As shown in Figure 8 and Figure 9, the structure of arotating shaft mechanism 10 provided by the embodiment of the present application includes: amain shaft 11, a pair ofrotating assemblies 12, and a pair of supports arranged on both sides of themain shaft 11plate 16. Each pair ofrotating assemblies 12 is arranged on both sides of themain shaft 11 along the direction perpendicular to the axis of themain shaft 11. Each rotatingassembly 12 includes one ormore swing arms 121, and eachswing arm 121 is pinned to the inner wall of themain shaft 11. . A pair ofsupport plates 16 are arranged on both sides of themain shaft 11 , and thesupport plates 16 on the same side of themain shaft 11 are arranged correspondingly to the rotatingassembly 12 . Wherein, one end of eachsupport plate 16 is rotatably connected to themain shaft 11 , and the opposite end is slidably connected to the rotatingassembly 12 and can rotate relatively. Alternatively, one end of eachsupport plate 16 is slidably connected to themain shaft 11 and can rotate relatively, and the opposite end is rotatably connected to the rotatingassembly 12 . 10 and 11, when the rotatingassembly 12 on both sides of themain shaft 11 is relatively rotated to the first position, the rotatingassembly 12 drives thecorresponding support plate 16 to rotate to the second position, and the supportingplate 16 on both sides of themain shaft 11 and An accommodation space is formed between themain shafts 11 .

其中，第一位置是指在转轴机构完全折叠状态时转动组件12所在位置，此时，主轴11两侧的转动组件12相互靠近，两侧的转动组件12上与移动终端壳体固定的固定面大致平行，图11里为左侧转动组件12的左侧面与右侧转动组件12的右侧面大致平行。第二位置是指在转轴机构完全折叠状态时支撑板16所在位置，此时，主轴11两侧的支撑板16相互靠近，两侧的支撑板16在靠近主轴11位置的间距比较宽，在远离主轴11位置的间距比较窄。Wherein, the first position refers to the position of the rotatingassembly 12 when the rotating shaft mechanism is completely folded. At this time, the rotatingassemblies 12 on both sides of themain shaft 11 are close to each other, and therotating assemblies 12 on both sides are fixed to the fixed surface of the mobile terminal housing. Roughly parallel, in FIG. 11 the left side of the left rotatingassembly 12 is approximately parallel to the right side of the right rotatingassembly 12 . The second position refers to the position of thesupport plate 16 when the rotating shaft mechanism is fully folded. At this time, thesupport plates 16 on both sides of themain shaft 11 are close to each other. The distance between the positions of themain shaft 11 is relatively narrow.

本申请实施例提供的转轴机构，参阅图8，在主轴11的两侧均布置有转动组件12与支撑板16，转动组件12的摆臂121与主轴11的内壁之间销轴连接。支撑板16连接于主轴11和转动组件12之间，这样在转动组件12相对主轴11转动时，转动组件12将会带动支撑板16相对主轴11转动。其中，在主轴11两侧的转动组件12转动至第一位置时，转动组件12将会带动两侧的支撑板16转动至第二位置，结合图7、图11，两侧的支撑板16在靠近主轴11位置的间距比较宽，在远离主轴11位置的间距比较窄，两侧支撑板16之间上部间距小而下部间距大，形成一个内凹的容纳空间，以容纳柔性屏40部分区域。结合图8，在主轴11两侧的转动组件12转动展开时，转动组件12带动对应的支撑板16转动展开，支撑板16可支撑在转动组件12上，主轴11与支撑板16可共同支撑柔性屏部分区域，支撑效果好。The rotating shaft mechanism provided by the embodiment of the present application, referring to FIG. 8 , has a rotatingassembly 12 and asupport plate 16 arranged on both sides of themain shaft 11 , and theswing arm 121 of the rotatingassembly 12 is pinned to the inner wall of themain shaft 11 . The supportingplate 16 is connected between themain shaft 11 and the rotatingassembly 12 , so that when the rotatingassembly 12 rotates relative to themain shaft 11 , the rotatingassembly 12 will drive the supportingplate 16 to rotate relative to themain shaft 11 . Wherein, when the rotatingassembly 12 on both sides of themain shaft 11 rotates to the first position, the rotatingassembly 12 will drive thesupport plates 16 on both sides to rotate to the second position. Referring to Fig. 7 and Fig. 11, thesupport plates 16 on both sides The spacing near themain shaft 11 is relatively wide, and the spacing away from themain shaft 11 is relatively narrow. The upper spacing between thesupport plates 16 on both sides is small and the lower spacing is large, forming a concave accommodation space to accommodate part of theflexible screen 40 . Referring to FIG. 8 , when the rotatingassembly 12 on both sides of themain shaft 11 rotates and expands, the rotatingassembly 12 drives thecorresponding support plate 16 to rotate and expand. In some areas of the screen, the support effect is good.

将上述转轴机构10应用到可折叠移动终端上，也就是将转轴机构10连接两个壳体之间，位于主轴11同一侧的转动组件12固定到对应的壳体上。结合图7，移动终端由展开状态至折叠状态的过程中，柔性屏40的中间区域42逐渐弯曲且截面形成水滴状，由于主轴11两侧的支撑板16与主轴11之间形成的容纳空间可容纳该柔性屏40的水滴状区域，这样就不会挤压柔性屏40且不起拱。反之，在折叠状态至展开状态的过程中，也不会拉扯到柔性屏40。在折叠与展开的过程中，柔性屏40也不会相对壳体滑动，降低了柔性屏40失效的风险，提高了柔性屏40的可靠性。相比于图2所示现有移动终端，采用图8所示转轴机构10的移动终端，主轴11两侧的转动组件12的摆臂121与主轴11的内壁之间销轴连接，采用双轴的方式实现两个壳体的连接，结合图5，移动终端在折叠状态时的厚度差异较小，两个壳体之间无较大的间隙，降低细长条物体掉入间隙而造成柔性屏损伤的可能性。The above-mentionedhinge mechanism 10 is applied to a foldable mobile terminal, that is, thehinge mechanism 10 is connected between two housings, and the rotatingassembly 12 located on the same side of themain shaft 11 is fixed to the corresponding housing. Referring to FIG. 7 , during the process of the mobile terminal from the unfolded state to the folded state, themiddle area 42 of theflexible screen 40 gradually bends and the cross-section forms a drop shape. Since the accommodation space formed between thesupport plates 16 on both sides of themain shaft 11 and themain shaft 11 can The drop-shaped area of theflexible screen 40 is accommodated so that theflexible screen 40 will not be squeezed and will not be arched. Conversely, theflexible screen 40 will not be pulled during the process from the folded state to the unfolded state. In the process of folding and unfolding, theflexible screen 40 will not slide relative to the housing, which reduces the risk of failure of theflexible screen 40 and improves the reliability of theflexible screen 40 . Compared with the existing mobile terminal shown in FIG. 2, the mobile terminal using theshaft mechanism 10 shown in FIG. The connection between the two housings is achieved by means of the above-mentioned method. Referring to Figure 5, the thickness difference of the mobile terminal in the folded state is small, and there is no large gap between the two housings, which reduces the possibility of flexible screens caused by slender objects falling into the gap. possibility of injury.

将上述转轴机构10应用到可折叠移动终端上，如图8所示，成对的转动组件12的摆臂121与主轴11的内壁之间销轴连接，位于主轴11同一侧的转动组件12固定于对应的壳体上，采用双轴的方式实现两个壳体的连接，两个壳体可实现折叠与展开动作。参阅图5，移动终端处于完全折叠状态时，从外部看该移动终端，只看到两个壳体之间连接有主轴11，而看不到两个壳体的连接位置存在缺口。相比于现有移动终端两个壳体之间采用单轴的连接方式，本申请实施例提供的转轴机构10采用双轴连接，单个转动组件12相对主轴11的转角可以更小，这样单个转动组件12与主轴11之间连接位置的结构体积可以更小，移动终端在完全展开状态时，转轴机构10并不会过多突出壳体。Apply the above-mentionedshaft mechanism 10 to a foldable mobile terminal, as shown in FIG. 8 , theswing arms 121 of the paired rotatingassemblies 12 are pinned to the inner wall of themain shaft 11, and therotating assemblies 12 located on the same side of themain shaft 11 are fixed. On the corresponding housing, the two housings are connected in a biaxial manner, and the two housings can realize folding and unfolding actions. Referring to FIG. 5 , when the mobile terminal is in a fully folded state, when the mobile terminal is viewed from the outside, only themain shaft 11 is connected between the two housings, but there is no gap at the connecting position of the two housings. Compared with the single-axis connection between the two housings of the existing mobile terminal, therotating shaft mechanism 10 provided by the embodiment of the present application adopts a double-axis connection, and the rotation angle of a singlerotating assembly 12 relative to themain shaft 11 can be smaller, so that a single rotation The structural volume of the connecting position between thecomponent 12 and themain shaft 11 can be smaller, and when the mobile terminal is fully unfolded, therotating shaft mechanism 10 does not protrude too much from the housing.

在具体设置主轴时，该主轴可以采用不同的结构，比如是一体结构或分体结构。参阅图12，本申请实施例提供的主轴11包括主外轴111以及主内轴112，主内轴112与主外轴111之间固定连接。作为一种示例，主外轴111的形状可以是半圆形的柱面结构，主内轴112可以是平面结构，主内轴112安装在主外轴111的开口处，主外轴111与主内轴112围成可容置一些零件的容置腔。主内轴112与主外轴111之间可以通过紧固部件(例如，螺钉15)可拆卸的固定连接。当然除了图12所示的连接方式外，还可以采用卡扣或者铆钉将主内轴112与主外轴111固定连接。When specifically setting the main shaft, the main shaft can adopt different structures, such as an integral structure or a split structure. Referring to FIG. 12 , themain shaft 11 provided by the embodiment of the present application includes a mainouter shaft 111 and a maininner shaft 112 , and the maininner shaft 112 and the mainouter shaft 111 are fixedly connected. As an example, the shape of the mainouter shaft 111 can be a semicircular cylindrical structure, the maininner shaft 112 can be a planar structure, the maininner shaft 112 is installed at the opening of the mainouter shaft 111, and the mainouter shaft 111 and the main Theinner shaft 112 encloses an accommodating cavity for accommodating some parts. The maininner shaft 112 and the mainouter shaft 111 can be detachably fixedly connected by fastening components (eg, screws 15 ). Of course, besides the connection method shown in FIG. 12 , buckles or rivets can also be used to fixedly connect the maininner shaft 112 and the mainouter shaft 111 .

在具体布置主轴与转动组件时，参阅图8、图9，主轴11的两端部分别设有一对转动组件12，转动组件12作为转轴机构10的主动部件。将转轴机构10安装于移动终端的两个壳体之间时，位于主轴11沿垂直于其轴线方向同侧的转动组件12与同侧的壳体固定连接，这样在壳体相对主轴11转动时，与该壳体同侧的转动组件12将会相对主轴11同步转动，而且转动过程比较平稳。When specifically arranging the main shaft and the rotating assembly, referring to FIG. 8 and FIG. 9 , a pair ofrotating assemblies 12 are respectively provided at both ends of themain shaft 11 , and the rotatingassembly 12 serves as an active part of therotating shaft mechanism 10 . When therotating shaft mechanism 10 is installed between the two housings of the mobile terminal, the rotatingassembly 12 located on the same side of themain shaft 11 along the direction perpendicular to its axis is fixedly connected to the housing on the same side, so that when the housing rotates relative to themain shaft 11 , the rotatingassembly 12 on the same side as the housing will rotate synchronously relative to themain shaft 11, and the rotating process is relatively stable.

在具体布置主轴与支撑板时，参阅图8，主轴11沿垂直于其轴线方向的两侧分别设有一个支撑板16，两个支撑板16可跟随主轴11两侧的转动组件12相对主轴11转动。可以理解的是，主轴11的任一侧还可以设置两个以上的支撑板16，将支撑板16连接在主轴11和转动组件12之间，使得转动组件12相对主轴11转动时多个支撑板16跟随转动。When specifically arranging the main shaft and the support plate, refer to FIG. 8 , themain shaft 11 is provided with asupport plate 16 on both sides perpendicular to its axis direction, and the twosupport plates 16 can follow the rotatingassembly 12 on both sides of themain shaft 11 relative to themain shaft 11. turn. It can be understood that more than twosupport plates 16 can be arranged on either side of themain shaft 11, and thesupport plates 16 are connected between themain shaft 11 and the rotatingassembly 12, so that when the rotatingassembly 12 rotates relative to themain shaft 11, multiple supportingplates 16 follows the rotation.

在一些实施例中，为了在两侧支撑板相互靠近时与主轴围成的容纳空间更大，参阅图11，主轴11的两侧均布置有转动组件12与支撑板16，转动组件12的摆臂121转动所绕的轴线O1有两根，支撑板16相对主轴11的转动轴线O3有两根，将支撑板16相对主轴11的转动轴线O3设置在摆臂121转动所绕的轴线O1的两侧。也就是说，摆臂121转动所绕的轴线O1在中部位置，支撑板16相对主轴11的转动轴线O3在两边外侧位置。在主轴11两侧的转动组件12转动至第一位置时，转动组件12将会带动两侧的支撑板16转动至第二位置，两侧的支撑板16在靠近主轴11位置的间距比较宽，在远离主轴11位置的间距比较窄，两侧支撑板16之间上部间距小而下部间距大，形成一个体积更大的内凹的容纳空间，以便于容纳柔性屏的水滴状区域。In some embodiments, in order to have a larger accommodation space surrounded by the main shaft when the support plates on both sides are close to each other, referring to FIG. There are two axes O1 around which thearm 121 rotates, and there are twosupport plates 16 relative to the axis O3 of rotation of themain shaft 11. side. That is to say, the axis O1 around which theswing arm 121 rotates is at the middle position, and thesupport plate 16 is at two outer positions relative to the rotation axis O3 of themain shaft 11 . When the rotatingassembly 12 on both sides of themain shaft 11 rotates to the first position, the rotatingassembly 12 will drive the supportingplates 16 on both sides to rotate to the second position, and the supportingplates 16 on both sides are relatively wide in the position close to themain shaft 11. The distance away from themain shaft 11 is relatively narrow, and the distance between thesupport plates 16 on both sides is small at the upper part and large at the bottom, forming a larger concave accommodation space for accommodating the drop-shaped area of the flexible screen.

When themain shaft 11 includes a main outer shaft and a main inner shaft, the rotating circular shaft can be arranged on the main outer shaft or the main inner shaft. A reliable and stable rotational connection between theswing arm 121 and themain shaft 11 can be realized by pivotally connecting therotating shaft 111c to the connectinghole 121a.

示例性的，转动圆轴111c设置于主轴11的轴线方向的端部内壁，摆臂121靠近主轴11的端部设置。将销轴连接的结构设置在主轴11端部，占用主轴11的内部空间较小，使得主轴11内部空间较大，可容置更多的零件。无需如现有移动终端在连接两个壳体之间的转轴壳外表面设置避让孔，无需在转轴壳的外表面覆盖柔性遮蔽件以遮蔽转轴壳的避让孔，并且无需设置使柔性遮蔽件随动的其它机构。本实施例的转轴机构中的主轴11具有完整的外观，摆臂121与主轴11的端部内壁之间销轴连接，结构简单，成本较低。Exemplarily, the rotatingcircular shaft 111c is disposed on the inner wall at the end of themain shaft 11 in the axial direction, and theswing arm 121 is disposed near the end of themain shaft 11 . The pin shaft connection structure is arranged at the end of themain shaft 11, which occupies less internal space of themain shaft 11, so that the internal space of themain shaft 11 is larger and can accommodate more parts. There is no need to set avoidance holes on the outer surface of the shaft shell connecting the two housings as in the existing mobile terminal, there is no need to cover the outer surface of the shaft shell with a flexible shield to cover the avoidance hole of the shaft shell, and there is no need to set the flexible shield to follow Other agencies that move.

Referring to FIG.

The connectingrod portion 131 is slidably mounted on the firstaccommodating groove 122 a, so that the rotatingassembly 12 is maintained at a certain rotational position relative to themain shaft 11 .

在一些实施例中，为了使转动组件更稳定可靠地维持在预定位置上，参阅图22，连杆部131靠近阻尼件141的侧壁设置有限位凹槽131a。在转动组件12相对主轴11转动时，连杆部131沿第一容置槽122a的延伸方向移动。在弹性结构件142的作用下，阻尼件141可沿连杆部131靠近第二容置槽122b的侧壁移动。由于连杆部131靠近第二容置槽122b的侧壁具有限位凹槽131a，这样阻尼件141在移动的过程中会在弹性结构件142的弹力作用下落入限位凹槽131a，以阻止阻尼件141继续在连杆部131上运动，从而使转动组件12停止转动，进而可使移动终端的壳体可靠地维持在对应的转动位。其中，连杆部131上的限位凹槽131a的数量可以为一个或多个，在连杆部131具有多个限位凹槽131a时，配合阻尼件141与弹性结构件142，可实现转动组件12在多个位置的可靠限位。其中，阻尼件141可以为滚珠或滑动体。阻尼件141为滚珠时，滚珠可沿连杆部131靠近第二容置槽122b的侧壁滚动，移动更灵活。阻尼件141为滑动体时，滑动体可沿连杆部131靠近第二容置槽122b的侧壁滑动，提供更好的阻尼力。滑动体可以设置与限位凹槽131a相适配的限位凸面，在滑动体移动至限位凹槽131a处，限位凸面将会滑入限位凹槽131a，相比于阻尼件采用滚珠的方式，阻尼件采用具有限位凸面的滑动体的方式可提供更大的阻尼力。In some embodiments, in order to maintain the rotating assembly at a predetermined position more stably and reliably, referring to FIG. 22 , a limitinggroove 131 a is provided on the side wall of the connectingrod portion 131 near the dampingmember 141 . When the rotatingassembly 12 rotates relative to themain shaft 11 , the connectingrod portion 131 moves along the extending direction of the firstaccommodating groove 122 a. Under the action of the elasticstructural member 142 , the dampingmember 141 can move along the side wall of the connectingrod portion 131 close to the secondaccommodating groove 122 b. Since the side wall of the connectingrod portion 131 near the secondaccommodating groove 122b has a limitinggroove 131a, the dampingmember 141 will fall into the limitinggroove 131a under the elastic force of the elasticstructural member 142 during the movement, so as to prevent The dampingmember 141 continues to move on thelink portion 131 , so that the rotatingassembly 12 stops rotating, so that the casing of the mobile terminal can be reliably maintained at a corresponding rotating position. Wherein, the number of limitinggrooves 131a on the connectingrod portion 131 can be one or more. When the connectingrod portion 131 has multiple limitinggrooves 131a, the dampingmember 141 and the elasticstructural member 142 can be used to realize rotation.

When the dampingelement 141 is a sliding body, the sliding body can slide along the side wall of the connectingrod portion 131 close to the secondaccommodating groove 122b to provide better damping force. The sliding body can be provided with a limiting convex surface compatible with the limitinggroove 131a. When the sliding body moves to the limitinggroove 131a, the limiting convex surface will slide into the limitinggroove 131a. In this way, the damping element adopts a sliding body with a limiting convex surface, which can provide greater damping force.

为了对可折叠移动终端的折叠状态改变以及维持做更好的说明，参阅图8、图23和图24，移动终端的两个壳体之间的夹角为180°，参阅图23，此时，阻尼件141落在限位凹槽131a中。当需要将移动终端的两个壳体之间的夹角从180°变为0°时，转动组件12绕主轴11转动，连杆部131随之转动，阻尼件141沿连杆部131的侧壁移动。参阅图25和图26，当阻尼件141落入限位凹槽131a中时，限位凹槽131a的槽壁阻止阻尼件141继续在连杆部131上运动，从而使转动组件12停止转动，进而使移动终端的两个壳体维持于0°夹角的状态。由于连杆部131靠近第二容置槽122b的侧壁具有多个限位凹槽131a，这样可通过使阻尼件141落入对应的限位凹槽131a中来实现转动组件12对应转动位的维持，例如，可通过合理设置使移动终端的两个壳体之间的夹角维持在90°。并且，在本申请实施方式中，参阅图27和图29，当阻尼件141在相邻两个限位凹槽131a之间运动时，会使其与连杆部131之间产生恒定的摩擦力，从而可实现转动组件12与连杆部131之间具有恒定的阻尼，此时可使手感恒定。另外，值得一提的是，参阅图23和图25，当连杆部131只在与移动终端的两个壳体之间的夹角为0°和180°相对应的位置设置有限位凹槽131a时，结合图25和图27，用户在折叠该移动终端时，只需手动使两个壳体之间具有较小的夹角(例如30°)，就可以使阻尼件141在弹性结构件142的作用下进入0°对应的限位凹槽131a，以实现两个壳体的自合；同样的，用户在展开该移动终端时，只需手动使两个壳体之间具有较大的夹角(例如150°)，就可以使阻尼件141在弹性结构件142的作用下进入180°对应的限位凹槽131a，以实现两个壳体的自开。由此可见，采用本技术方案的转轴机构10，可以实现可折叠移动终端的自开合，从而有利于提升用户体验。In order to better explain the change and maintenance of the folding state of the foldable mobile terminal, refer to Figure 8, Figure 23 and Figure 24, the angle between the two shells of the mobile terminal is 180°, refer to Figure 23, at this time , the dampingelement 141 falls into the limitinggroove 131a. When it is necessary to change the angle between the two housings of the mobile terminal from 180° to 0°, the rotatingassembly 12 rotates around themain shaft 11, and the connectingrod portion 131 rotates accordingly, and the dampingmember 141 moves along the side of the connectingrod portion 131. The wall moves. 25 and 26, when the dampingmember 141 falls into the limitinggroove 131a, the groove wall of the limitinggroove 131a prevents the dampingmember 141 from continuing to move on the connectingrod portion 131, so that the rotatingassembly 12 stops rotating, Furthermore, the two casings of the mobile terminal are maintained at an angle of 0°. Since the side wall of the connectingrod portion 131 near the secondaccommodating groove 122b has a plurality of limitinggrooves 131a, the corresponding rotation position of the rotatingassembly 12 can be achieved by making the dampingmember 141 fall into the corresponding limitinggroove 131a. To maintain, for example, the angle between the two casings of the mobile terminal can be maintained at 90° through reasonable settings. Moreover, in the embodiment of the present application, referring to FIG. 27 and FIG. 29 , when the dampingmember 141 moves between two adjacent limitinggrooves 131a, a constant frictional force will be generated between it and the connectingrod portion 131 , so that constant damping between the rotatingassembly 12 and the connectingrod portion 131 can be achieved, and at this time, the hand feeling can be kept constant. In addition, it is worth mentioning that, referring to Fig. 23 and Fig. 25, when thelink part 131 is only provided with a limiting groove at the position corresponding to the angle between the two housings of the mobile terminal being 0° and 180° 131a, with reference to Figure 25 and Figure 27, when the user folds the mobile terminal, the user only needs to manually make the two housings have a small angle (for example, 30°), and the dampingmember 141 can be placed on the elasticstructural member 142 enters thelimit groove 131a corresponding to 0° to realize the self-closing of the two housings; similarly, when the user unfolds the mobile terminal, he only needs to manually make a larger gap between the two housings. The included angle (for example, 150°) enables the dampingmember 141 to enter the corresponding limitinggroove 131a of 180° under the action of the elasticstructural member 142, so as to realize the self-opening of the two shells. It can be seen that, by adopting thehinge mechanism 10 of the technical solution, the self-opening and closing of the foldable mobile terminal can be realized, which is beneficial to improving user experience.

The direction of extension is the same, wherein, the setting position of theguide groove 122c can be various. In the embodiment shown in Fig. 9 and Fig. 22, theguide groove 122c is set at the position where thefirst accommodation groove 122a is away from thesecond accommodation groove 122b on the tank wall. Referring to FIG. 22 , thedisplacement assembly 13 further includes a slidingportion 133 disposed on the connectingrod portion 131 and slidingly fitted in theguide groove 122c. Wherein, the slidingportion 133 may be, but not limited to, a cylindrical protrusion disposed on a side of the connectingrod portion 131 close to theguide groove 122c. During the rotation of the connectingrod portion 131 of thedisplacement assembly 13 with therotation assembly 12, the slidingportion 133 is limited to theguide groove 122c and can slide along theguide groove 122c, so that thedisplacement assembly 13 can be avoided during the rotation of therotation assembly 12. Breaking away from the rotatingassembly 12 effectively improves the reliability of the movement of thedisplacement assembly 13 . Of course, in order to achieve the above purpose, a way such as disposing a blocking piece in the firstaccommodating groove 122a may also be adopted.

为了实现连杆部131与主轴11的转动连接，参阅图14，可以采用在主外轴111上设置第三容置槽111a的方案。具体的，主外轴111上设置有第三容置槽111a，结合图12，主内轴112设置有用于露出第三容置槽111a的开口112a；结合图13，连杆部131的第一端容置于第三容置槽111a，且与主轴11转动连接。连杆部131的第一端设置有支撑轴132，第三容置槽111a包括可容置该支撑轴132的圆弧面111b。采用该结构时，需要先将连杆部131的支撑轴132放置于第三容置槽111a的圆弧面111b上，然后将主内轴112盖设于主外轴111上并加以紧固，从而可使支撑轴132卡设于第三容置槽111a，并可沿圆弧面111b转动。结合图8，在主轴11两侧的转动组件12完全展开时，支撑轴132将会被主内轴112的内壁挡住以限定连杆部131的位置，从而限定位移组件13相对主轴11的转动位置。位移组件13还可通过铰接或者枢装等方式来实现与主轴11的转动连接，结合图12，位移组件13在转动的过程中，主内轴112的开口112a不会对其造成干涉。In order to realize the rotational connection between the connectingrod portion 131 and themain shaft 11 , referring to FIG. 14 , a solution of providing a thirdaccommodating groove 111 a on the mainouter shaft 111 may be adopted. Specifically, the mainouter shaft 111 is provided with athird accommodation groove 111a. Referring to FIG. 12, the maininner shaft 112 is provided with anopening 112a for exposing thethird accommodation groove 111a; referring to FIG. 13, the first The end is accommodated in the thirdaccommodating groove 111 a and is rotatably connected with themain shaft 11 .

When adopting this structure, it is necessary to place the supportingshaft 132 of the connectingrod portion 131 on thearc surface 111b of the thirdaccommodating groove 111a, and then cover the maininner shaft 112 on the mainouter shaft 111 and fasten it. Therefore, thesupport shaft 132 can be clamped in thethird receiving groove 111a, and can rotate along thearc surface 111b. Referring to FIG. 8 , when the rotatingassembly 12 on both sides of themain shaft 11 is fully deployed, thesupport shaft 132 will be blocked by the inner wall of the maininner shaft 112 to define the position of the connectingrod portion 131 , thereby limiting the rotational position of thedisplacement assembly 13 relative to themain shaft 11 . Thedisplacement assembly 13 can also be rotatably connected to themain shaft 11 by means of hinged or pivotal mounting. Referring to FIG. 12 , theopening 112a of the maininner shaft 112 will not interfere with thedisplacement assembly 13 during rotation.

在一些实施例中，在具体设置弹性结构件时，在图22、图24所示的实施例中，转动组件12与阻尼组中的位移组件13、限位组件14为一一对应的设置关系。转动组件12还包括设置于第二容置槽122b远离位移组件13一端的挡板123，弹性结构件142的一端固定于该挡板123。其中，弹性结构件142可以但不限于为弹簧，当弹性结构件142为弹簧时，为了实现对弹簧的限位，以使其在运动过程中不发生弯折，可以在挡板123上设置限位支柱124，从而使弹簧套设于限位支柱124，其中，弹簧可以为一条，也可以为多条，这样可以通过改变弹簧的数量来改变位移组件13与转动组件12之间的阻尼力的大小，除此之外，还可以通过改变弹簧的刚性来改变阻尼力的大小。在该弹簧靠近位移组件13的一端还设置有连接板142a，连接板142a卡接于第二容置槽122b的槽壁，以使弹簧能够限位于第二容置槽122b。连接板142a上也可以设置限位支柱124，并使弹簧套设于该限位支柱124。此时，阻尼件141与连接板142a相抵接，并可沿连接板142a的表面运动，这样可减小弹性结构件142与阻尼件141之间的摩擦，使阻尼件141的运动更加灵活。In some embodiments, when specifically setting up the elastic structural members, in the embodiments shown in Fig. 22 and Fig. 24, the rotatingassembly 12 has a one-to-one correspondence with thedisplacement assembly 13 and thelimit assembly 14 in the damping group. . Therotation assembly 12 further includes abaffle 123 disposed at an end of thesecond receiving groove 122 b away from thedisplacement assembly 13 , and one end of the elasticstructural member 142 is fixed to thebaffle 123 . Wherein, the elasticstructural member 142 can be, but not limited to, a spring. When the elasticstructural member 142 is a spring, in order to realize the limit to the spring so that it does not bend during the movement, a limiter can be set on thebaffle 123.Position support 124, so that the spring is sleeved on thelimit support 124, wherein, the spring can be one or more, so that the damping force between thedisplacement assembly 13 and therotation assembly 12 can be changed by changing the number of springs. In addition to this, the damping force can also be changed by changing the stiffness of the spring. A connectingplate 142a is provided at the end of the spring close to thedisplacement assembly 13, and the connectingplate 142a is engaged with the groove wall of thesecond receiving groove 122b, so that the spring can be limited in thesecond receiving groove 122b. A limitingpillar 124 may also be disposed on the connectingplate 142 a, and a spring is sleeved on the limitingpillar 124 . At this time, the dampingelement 141 abuts against the connectingplate 142a and can move along the surface of the connectingplate 142a, which can reduce the friction between theelastic structure 142 and the dampingelement 141, and make the movement of the dampingelement 141 more flexible.

为了改变位移组件13与转动组件12之间的阻尼力的大小还可以通过改变阻尼件141的数量来实现，具体的，在图9所示的实施例中，一个转动组件12设置有两个位移组件13，两个位移组件13共用一个限位组件(图中未显示)，转动组件12、限位组件以及主轴11的设置方式稍有不同。其中，转动组件12设置有两个用于容置位移组件13的第一容置槽122a，主轴11上的第三容置槽111a与第一容置槽122a一一对应设置，以使位移组件13能够一一对应的容置于第一容置槽122a以及第三容置槽111a。此时，在具体设置弹性结构件142时，可参阅图24，不同的是使弹性结构件142的两端各设置一个阻尼件141，并使阻尼件141能够沿对应的位移组件13的连杆部131侧壁移动。可以理解的是，在该实施方式中，两个连杆部131相对设置的侧壁上均设置有多个一一对应的限位凹槽131a。弹性结构件142的具体设置方式可参阅上一实施例，由弹簧或弹簧组，以及设置于弹簧(或弹簧组)端部的连接板142a组成，阻尼件141与对应侧的连接板142a相抵接。其中，为避免弹簧(或弹簧组)在运动的过程中发生弯折，可在连接板142a上设置限位支柱，并使弹簧套设于对应的限位支柱即可。采用该种设置方式可以有效的增加限位组件14与连杆部131之间的阻尼力，从而实现包含有该转动组件12的可折叠移动终端的折叠状态的有效维持。另外，参阅图9、图10，位于主轴11同一侧的转动组件12之间可通过加强杆125连接，这样可以提高结构强度。In order to change the damping force between thedisplacement assembly 13 and therotation assembly 12, it can also be realized by changing the number of dampingmembers 141. Specifically, in the embodiment shown in FIG. 9, onerotation assembly 12 is provided with two displacement As for theassembly 13, the twodisplacement assemblies 13 share a limit assembly (not shown in the figure), and the arrangement of therotation assembly 12, the limit assembly and themain shaft 11 is slightly different. Wherein, the rotatingassembly 12 is provided with two firstaccommodating grooves 122a for accommodating thedisplacement assembly 13, and the thirdaccommodating groove 111a on themain shaft 11 is provided in one-to-one correspondence with the firstaccommodating groove 122a, so that thedisplacement assembly 13 can be accommodated in the firstaccommodating groove 122a and the thirdaccommodating groove 111a in one-to-one correspondence. At this time, when specifically setting the elasticstructural member 142, refer to FIG. 24 , the difference is that a dampingmember 141 is provided at both ends of the elasticstructural member 142, and the dampingmember 141 can move along the connecting rod of thecorresponding displacement assembly 13. The side walls of theportion 131 move. It can be understood that, in this embodiment, a plurality of one-to-one corresponding limitinggrooves 131 a are provided on the opposite side walls of the two connectingrod parts 131 . The specific arrangement of the elasticstructural member 142 can refer to the previous embodiment, which is composed of a spring or a spring group, and a connectingplate 142a arranged at the end of the spring (or spring group), and the dampingmember 141 is in contact with the connectingplate 142a on the corresponding side . Wherein, in order to prevent the spring (or spring group) from being bent during the movement, a limit post can be provided on the connectingplate 142a, and the spring can be sleeved on the corresponding limit support. Adopting such an arrangement can effectively increase the damping force between the limitingcomponent 14 and thelink portion 131 , so as to effectively maintain the folded state of the foldable mobile terminal including therotating component 12 . In addition, referring to FIG. 9 and FIG. 10 , the rotatingcomponents 12 located on the same side of themain shaft 11 can be connected by reinforcingrods 125 , which can improve the structural strength.
