为了解决上述技术问题，本申请是这样实现的：

下面结合图1-图3描述根据本申请实施例的折叠装置和电子设备。
如图1和图2所示，根据本申请一些实施例的折叠装置，包括：轴部1，轴部1包括至少两个转轴；第一摆臂3和第二摆臂4，第一摆臂3包括第一连接部30，第二摆臂4包括第二连接部40，第一连接部30和第二连接部40分别套设于转轴上，第一摆臂3和第二摆臂4能够相对于转轴转动，沿转轴的轴向，第一连接部30的端部和第二连接部40的端部均具有限位凸起5；阻尼机构2，包括第一阻尼件22，第一阻尼件22套设于转轴，沿转轴的轴向，第一阻尼件22的一端与转轴固定连接，第一阻尼件22的另一端具有限位凹陷229，限位凹陷229与限位凸起5配合运动，在第一摆臂3和第二摆臂4转动的情况下，限位凸起5与限位凹陷229退出限位配合状态，限位凸起5推动第一阻尼件22，使第一阻尼件22的至少一部分形变；同步机构6，同步机构6的至少一部分设于第一连接部30和第二连接部40，第一连接部30上的部分同步机构6和第二连接部40上的部分同步机构6相对设置且相连接，第一摆臂3和第二摆臂4通过同步机构6同步转动。
在本申请的实施例中，折叠装置包括轴部1、第一摆臂3、第二摆臂4、阻尼机构2和同步机构6，第一摆臂3和第二摆臂4能够绕转轴转动，进而实现折叠装置的折叠或展开。阻尼机构2包括第一阻尼件22，沿轴部1的轴向方向，第一阻尼件22一端与转轴固定连接，另一端设置有限位凹陷229，这样，在第一摆臂3和第二摆臂4转动时，能够通过第一连接部30和第二连接部40上的限位凸起5驱动第一阻尼件22运动，使得限位凸起5与限位凹陷229退出配合状态，进而驱动第一阻尼件22的至少一部分形变，实现折叠装置的悬停，提升折叠装置的开合手感。其中，同步机构6的至少一部分设置在第一连接部30和第二连接部40上，也即将同步机构6与阻尼机构2整合在一起，减小了同步机构6在轴向方向的占用长度，进而缩短同步机构6与阻尼机构2整体长度，从而提升了折叠装置的空间利用率，这样，在折叠装置上能够设置更多的阻尼机构2，进而提升阻尼机构2的阻尼力。
可以理解的是，由于将同步机构6的至少一部分设置在第一连接部30和第二连接部40上，且第一连接部30上的部分同步机构6和第二连接部40上的部分同步机构6相对设置，进而同步机构6的至少一部分不单独占用轴向长度，缩短了同步机构6在轴向上的占用空间，提升了折叠装置的空间利用率，进而能够放置更多的阻尼机构2，以提升折叠装置的阻尼力。
需要说明的是，第一连接部30的两端中的至少一端设有至少一个限位凸起5，沿转轴的轴向，第一连接部30的端部还设有凹位，凹位与限位凸起5相邻，相应地，第二连接部40的两端中的至少一端设有至少一个限位凸起5，沿转轴的轴向，第二连接部40的端部还设有凹位，凹位与限位凸起5相邻。
同时，第一阻尼件22的一端设置有限位凹陷229，第一阻尼件22的一端还设有凸位，沿转轴的周向，限位凹陷229和凸位相邻设置。
具体地，在限位凹陷229与限位凸起5处于限位配合状态时，限位凸起5位于限位凹陷229内，凸位位于凹位内；在第一摆臂3和第二摆臂4转动的过程中，限位凸起5由限位凹陷229向凸位运动，进而驱动阻尼机构2运动，使得阻尼机构2的至少一部分形变，进而增加运动的阻尼力，使得折叠装置具有悬停的效果。
在具体应用中，沿转轴的轴向，第一连接部30的两端均设有限位凸起5，且第一连接部30的任一端设有多个限位凸起5，沿转轴的周向，相邻的限位凸起5之间形成凹位。沿转轴的轴向，第二连接部40的两端均设有限位凸起5，且第二连接部40的任一端设有多个限位凸起5，沿转轴的周向，相邻的限位凸起5之间形成凹位。相应地，第一阻尼件22设置有多个限位凹陷229，沿转轴的周向，相邻的限位凹陷229之间形成凸位。
具体地，第一阻尼件22的一端与转轴固定连接，第一阻尼件22的另一端具有限位凹陷229，这样，在第一摆臂3和第二摆臂4转动时，通过限位凸起5与限位凹陷229的作用，使得第一阻尼件22设置有限位凹陷229的一端向与转轴固定的一端运动，进而压缩第一阻尼件22，使得第一阻尼件22形变，实现折叠装置的悬停。
另外，可以理解的是，阻尼机构2还包括除第一阻尼件22以外的其他结构。
根据本申请的一些实施例，同步机构6包括：第一传动部，设于第一连接部30；第二传动部，设于第二连接部40，第一传动部和第二传动部相对设置且相连接。
在该实施例中，同步机构6包括第一传动部和第二传动部，第一传动部设置在第一连接部30上，第二传动部设置在第二连接部40上，这样使得第一摆臂3和第二摆臂4能够同步运动。
可以理解的是，第一传动部和第二传动部可以直接连接，也可以通过其他结构连接。
根据本申请的一些实施例，第一传动部包括第一齿部34，第二传动部包括第二齿部44，第一齿部34和第二齿部44相啮合。
在该实施例中，第一传动部包括第一齿部34，第二传动部包括第二齿部44，第一齿部34和第二齿部44直接啮合，一方面实现了第一摆臂3和第二摆臂4的同步运动，提升运动的平稳性和可靠性，另一方面还能够减少同步机构6的零部件数量，进而减少同步机构6的整体体积，增加折叠装置的空间利用率。
如图3所示，根据本申请的一些实施例，第一传动部包括第一齿部34，第二传动部包括第二齿部44，同步机构6还包括：第一齿轮60和第二齿轮62，设于第一齿部34和第二齿部44之间，第一齿轮60和第二齿轮62相啮合，第一齿部34和第一齿轮60啮合， 第二齿轮62与第二齿部44啮合。
在该实施例中，第一连接部30上设置有第一齿部34，第二连接部40上设置有第二齿部44，第一齿轮60和第二齿轮62啮合传动，第一齿部34与第一齿轮60啮合传动，第二齿部44与第二齿轮62啮合传动，从而实现第一摆臂3和第二摆臂4的同步转动，并且通过在第一摆臂3和第二摆臂4上设置齿部，减少了齿轮结构的数量，降低了制造成本。
可以理解的是，第一齿轮60和第二齿轮62的转动轴线与轴部1的轴线方向相同。
如图2和图3所示，根据本申请的一些实施例，第一传动部与第一连接部30为一体式结构，第二传动部与第二连接部40为一体式结构。
在该实施例中，第一传动部与第一连接部30为一体式结构，第二传动部与第二连接部40为一体式结构，提升了第一连接部30与第一传动部、第二传动部与第二连接部40的连接强度和可靠性，同时，还能够减少第一传动部和第二传动部的占用空间，进一步缩小了同步机构6在转轴的轴向上长度的占用。
在具体应用中，第一连接部30的一部分构造为第一传动部，第二连接部40的一部分构造为第二传动部，进一步缩小了第一传动部和第二传动部空间的占用。
进一步地，第一连接部30与第一传动部一体制造而成，第二连接部40与第二传动部一体制造而成。
如图2和图3所示，根据本申请的一些实施例，阻尼机构2还包括：第二阻尼件24，第二阻尼件24固定于转轴，第二阻尼件24和第一阻尼件22间隔设置，同步机构6与第二阻尼件24连接，沿转轴的轴向，第一摆臂3和第二摆臂4设于第二阻尼件24和第一阻尼件22之间，其中，第二阻尼件24朝向第一阻尼件22的一端设有限位凹陷229，第一连接部30和第二连接部40朝向第二阻尼件24的一端均设有限位凸起5，限位凹陷229与限位凸起5配合运动，第一摆臂3和第二摆臂4驱动第二阻尼件24和第一阻尼件22相远离或相靠近。
在该实施例中，第二阻尼件24和第一阻尼件22沿轴部1的轴向间隔设置，第二阻尼件24固定于转轴，沿轴部1的轴向，第一摆臂3和第二摆臂4设置在第二阻尼件24和第一阻尼件22之间，这样，在第一摆臂3和第二摆臂4相对于轴部1转动的情况下，能够驱动第二阻尼件24和第一阻尼件22相远离，进而使得第一阻尼件22被压缩，进而实现阻尼机构2的阻尼效果。同时，在第一摆臂3和第二摆臂4的作用下，还能够使得第二阻尼件24和第一阻尼件22相靠近，从而使得阻尼机构2复位。
进一步地，沿轴部1的轴向，第一摆臂3的第一端、第二摆臂4的第一端均与第二阻尼件24接触，第一摆臂3的第二端、第二摆臂4的第二端均与第一阻尼件22接触。
在具体应用中，沿转轴的轴向，第一连接部30的两端均设置有限位凸起5，第二连接部40的两端均设置有限位凸起5，第二阻尼件24上对应第一连接部30和第二连接部40的部分均设置有限位凹陷229，第一阻尼件22对应第一连接部30和第二连接部40的部分均设置有限位凹陷229。
如图2所示，根据本申请的一些实施例，第一阻尼件22包括：从动件228，与转轴活动连接，从动件228朝向第二阻尼件24的一侧设有限位凹陷229；挡板220，固设于转轴；第一弹性件222，套设于至少两个转轴中的一个转轴，第一弹性件222的一端与从动件228接触，另一端与挡板220接触；第二弹性件224，套设于至少两个转轴中的另一个转轴，第二弹性件224的一端与从动件228接触，另一端与挡板220接触。
在该实施例中，第一阻尼件22包括从动件228、挡板220、第一弹性件222和第二弹性件224。从动件228与转轴活动连接，且从动件228上设置有限位凹陷229。第一弹性件222套设在一个转轴上，第二弹性件224套设在另一个转轴上，挡板220固设在转轴，且挡板220位于第一弹性件222和第二弹性件224远离从动件228的一端，从而实现第一弹性件222和第二弹性件224的限位。通过挡板220的设置，能够便于第一弹性件222和第二弹性件224的组装，同时，还能够在第二阻尼件24带动轴部1移动时，通过固设在转轴上的挡板220实现对第一弹性件222和第二弹性件224的进一步挤压，进而增加第一弹性件222和第二弹性件224的形变量。
另外，本申请提出的折叠装置中，第一弹性件222和第二弹性件224设置在第一摆臂3和第二摆臂4的外侧，不需要在第一摆臂3和第二摆臂4中间增设阻尼件，因此减小了第一阻尼件22的轴向长度，提升了折叠装置的空间利用率。同时，通过在第一弹性件222和第二弹性件224的轴向两端均施加挤压力，使得第一弹性件222和第二弹性件224的形变量得到增加，进而提升了阻尼力。
具体地，挡板220卡设于第一轴部1和第二轴部1。
可以理解的是，在第一摆臂3和第二摆臂4的驱动下，第二阻尼件24向远离第一阻尼件22的方向移动，由于第二阻尼件24固设于轴部1，因此带动轴部1向远离第一阻尼件22的方向移动。同时，在第一摆臂3和第二摆臂4的驱动下，从动件228向远离第二阻尼件24的方向移动，由于从动件228活动设于转轴，因此能够沿转轴移动。这样，第二阻尼件24带动转轴相对于第一阻尼件22运动，挡板220在转轴的带动下向从动件228方向移动，能够对第一弹性件222和第二弹性件224产生挤压力，使得第一弹性件222和第二弹性件224形变。从动件228在第一摆臂3和第二摆臂4的作用下向第一弹性件222和第二弹性件224运动，能够对第一弹性件222和第二弹性件224产生挤压力，进而在第二阻尼件24和从动件228的共同作用下，使得第一弹性件222和第二弹性件224产生的阻尼力增加，进而提升了阻尼机构2的阻尼效果。
如图2所示，根据本申请的一些实施例，第一阻尼件22还包括：连接轴227，连接轴227与从动件228活动连接；第三弹性件226，位于第一弹性件222和第二弹性件224之间，第三弹性件226套设于连接轴227，第三弹性件226的一端与从动件228接触，另一端与挡板220接触。
在该实施例中，第一阻尼件22还包括第三弹性件226，第三弹性件226设置在第一弹性件222和第二弹性件224之间，其中，从动件228和挡板220之间连接有连接轴227， 第三弹性件226套设在连接轴227上，并能够沿连接轴227活动，进而与第一弹性件222和第二弹性件224一同实现形变，增加阻尼力。
其中，连接轴227与从动件228活动连接，连接轴227与挡板220固定连接。从而在第二阻尼件24带动轴部1运动时，能够使得第三弹性件226沿连接轴227的轴向运动。
在具体应用中，第一弹性件222、第二弹性件224和第三弹性件226为弹簧。
可以理解的是，相关技术中，将弹簧放置在第一摆臂3和第二摆臂4的轴向内部和外部，一方面增加了弹簧总体占用的轴向长度，另一方面，还需要将弹簧预压缩后进行装配，增加了装配难度。同时，相关技术中单方向对弹簧进行挤压，而本申请在弹簧的轴向双方向进行挤压，对于一个弹簧而言，本申请提出的阻尼机构2中弹簧的形变量为相关技术中弹簧形变量的两倍，从而相比于相关技术，阻尼力得到了很大的提升。
如图2所示，根据本申请的一些实施例，第一连接部30上设有第一缺口32，第二连接部40上设有第二缺口42；折叠装置还包括隔板7，隔板7与转轴连接，位于第一缺口32和第二缺口42处，第一连接部30、第二连接部40、第二阻尼件24和隔板7合围出容纳腔9，同步机构6的第一齿轮60和第二齿轮62设于容纳腔9内。
在该实施例中，第一连接部30上设置有第一缺口32，第二连接部40上设置有第二缺口42，隔板7设置在第一缺口32和第二缺口42处，隔板7连接于轴部1上，使得隔板7与第一连接部30、第二连接部40和第二阻尼件24合围出容纳腔9，第一齿轮60和第二齿轮62设置在容纳腔9内，减少了同步机构6在转轴的轴向上的占用长度，进而提升了折叠装置的空间利用率，以便于增加更多的阻尼机构2。同步机构6通过转动轴与隔板7连接，提升了同步机构6的连接可靠性。
在具体应用中，第一齿轮60和第二齿轮62通过转动轴设于第二阻尼件24的轴孔上，并与第二阻尼件24活动连接，使得第一齿轮60和第二齿轮62的转动轴能够相对于第二阻尼件24轴向运动。
根据本申请的一些实施例，折叠装置还包括：导向机构8，导向机构8与轴部1连接，位于阻尼机构2的一端。
在该实施例中，折叠装置还包括导向机构8，导向机构8实现了阻尼机构2的运动的导向，使得阻尼机构2能够按照预定的轨迹运动。
根据本申请的一些实施例，阻尼机构2、同步机构6和导向机构8构成折叠部，折叠部的数量为多个，多个折叠部沿轴部1的轴向间隔设置。
在该实施例中，阻尼机构2、同步机构6和导向机构8共同构成折叠部，其中，折叠部的数量为多个，多个折叠部的设置增加了折叠装置的阻尼力。
在具体应用中，折叠部的数量为三个，也即，折叠装置具有三个阻尼机构2、三个同步机构6和三个导向机构8。相比于相关技术，增加了一组阻尼机构2、同步机构6和导向机构8，进而增加了至少50％的阻尼力。
如图2和图3所示，具体地，至少两个转轴包括：第一转轴10，第一摆臂3与第一 转轴10连接；第二转轴12，与第二转轴12相对设置，第二摆臂4与第二转轴12连接，第二阻尼件24与第一转轴10和第二转轴12固定连接，从动件228与第一转轴10和第二转轴12活动连接，第一弹性件222套设在第一转轴10上，第二弹性件224套设在第二转轴12上。
在该实施例中，轴部1包括第一转轴10和第二转轴12。第一摆臂3与第一转轴10连接，第二摆臂4与第二转轴12连接，使得第一摆臂3和第二摆臂4能够相对运动，实现折叠装置的开合。
根据本申请的一些实施例，提出了一种电子设备，包括：如上述任一实施例提出的折叠装置。
在该实施例中，电子设备因包括上述任一实施例提出的折叠装置，因此具有折叠装置的全部有益效果。
在具体应用中，本申请提出的折叠装置，将第一摆臂3、第二摆臂4的悬臂减短，第一摆臂3和第二摆臂4上设置有限位凸起5，限位凸起5的配合面为朝两外侧，弹簧放置在第一摆臂3、第二摆臂4一端的外侧，通过轴部1的轴向移动来传递限位凸起5的位移量。
如图3所示，当折叠装置做开合动作时，第一摆臂3、第二摆臂4绕轴部1转动，第一摆臂3、第二摆臂4两侧有限位凸起5，弹簧的一端直接受从动件228的挤压，如图挤压弹簧力F1，弹簧另一端的压缩是通过第二阻尼件24带动轴部1的轴向移动，传递给挡板220轴向移动，挡板220挤压弹簧提供阻尼力，如图挤压弹簧力F2。
折叠装置两侧开合动作的同步是通过一对第一摆臂3、第二摆臂4结合第一齿轮60和第二齿轮62实现的，第一摆臂3、第二摆臂4加工出齿部，第一摆臂3、第二摆臂4之间啮合第一齿轮60和第二齿轮62进行同步运动。
阻尼机构2各部分作用及相互关系如下：
1、第一摆臂3、第二摆臂4与第二阻尼件24和从动件228安装在轴部1上，通过限位凸起5和限位凹陷229配合，其中第一摆臂3、第二摆臂4可绕着轴部1的中心实现回转运动，带动第二阻尼件24和从动件228做轴向往复运动，第二阻尼件24与轴部1固定，挡板220与轴部1固定，因此第二阻尼件24的往复运动通过轴部1传递给挡板220做轴向往复运动。
2、第一齿轮60和第二齿轮62安装在第二阻尼件24的轴孔上，第一齿轮60和第二齿轮62啮合在一起，并与第一摆臂3的第一齿部34、第二摆臂4的第二齿部44啮合，实现折叠装置两侧机身的同步。
3、弹簧安装在轴部1上，位于从动件228的外侧，一端在从动件228上，另一端通过挡板220固定，挡板220与轴部1固定，随着轴部1的轴向移动而移动，进而挤压弹簧。
本申请提出的折叠装置，至少具有如下优点：
1、折叠装置内部空间利用率高，相比于常规的折叠装置，本申请提出的折叠装置能 够多放置一个阻尼机构2、一个导向机构8、一个同步机构6。
具体地：将阻尼机构2与同步机构6结合在一起，同步机构6不再单独占用折叠装置的长度空间。阻尼机构2本身的空间利用率提升，减少了阻尼机构2占据折叠装置的空间，申请节省了阻尼机构2中一个弹簧长度的空间。
2、本申请提出的折叠装置的阻尼力相比于常规折叠装置提升50％；同等空间内，本申请提出的折叠装置相比于常规折叠装置多放置一个阻尼机构2，阻尼力得到提升；针对阻尼机构2本身，同样的位移量由常规方案的分别施加给四个弹簧单向挤压，改进为全部施加给三个弹簧双向挤压，那么针对一个弹簧来说，形变量为常规方案的二倍，阻尼力得到提升。
3、便于组装：相关技术中的弹簧需压缩后塞入装配，本申请的弹簧无需塞入装配，通过后装配卡扣挡板220固定。
4、本申请提出的折叠装置可靠性高，减短了第一摆臂3和第二摆臂4的的悬臂长度，可靠性得到了提升。
需要说明的是，电子设备可以为手机、平板电脑、笔记本电脑、电子书。学习机等。
