在介绍本申请的技术方案之前，再详细介绍下相关技术中的技术问题。
在机械组件领域中，扭矩组件通常被用于多种结构中以实现悬停，例如门锁、电子设备等。但是目前扭矩组件的摩擦性能较差，悬停效果较差，且结构尺寸较大。例如，当扭矩组件用于U型折叠屏手机时，折叠屏手机通常需要扭矩组件提供大于预设力的摩擦力实现悬停。但是，由于需要确保提供的外力大于预设力以实现悬停，扭矩组件中部件的尺寸较大，例如相关技术中扭矩组件的凸轮、转轴、转动件等，导致扭矩组件的整体结构尺寸较大。更具体地，目前相关技术中，多数使用包含凸轮配合的专业扭力组件。但是，通过仿真与计算表明，单独使用凸轮实现悬停功能，需要凸轮尺寸满足扭力要求，导致扭力组件的整体尺寸较大，从而导致扭矩组件需占用更多手机的内部空间，且需限制手机中其他组件的尺寸，降低手机性能。例如，当手机电池的尺寸被限制时，易导致手机电能存储量降低，手机的续航能力降低。
鉴于此，为了解决上述问题，本申请提供了一种扭矩组件，请一并参考图1-图2，图1为本申请一实施方式中扭矩组件的立体结构示意图。图2为本申请一实施方式图1中的爆炸图。
本实施方式提供了一种扭矩组件1，包括转轴11、第一阻挡件12、转动件13、滑动件14、第二阻挡件15、第一弹性件16。其中，第一阻挡件12固定于转轴11；转动件13套设于转轴11，转动件13套设转轴11的部分在背离第一阻挡件12的一端设有第一配合部131；滑动件14套设于转轴11，滑动件14位于转动件13背离第一阻挡件12的一侧，且滑动件14套设转轴11的部分在靠近第一阻挡件12的一端设有第二配合部141；第二阻挡件15固定于转轴11，第二阻挡件15位于滑动件14背离第一阻挡件12的一侧；第一弹性件16套设于转轴11，第一弹性件16位于滑动件14与第二阻挡件15之间。其中，当转动件13转动时，第一配合部131与第二配合部141相互配合使滑动件14朝向靠近或远离转动件13的方向滑动；当滑动件14朝向远离转动件13的方向滑动时，第一弹性件16处于压缩状态且使滑动件14抵接转动件13；当转动件13停止转动时，转动件13处于稳定状态。
此外，术语“包括”和“具有”以及它们任何变形，意图在于覆盖不排他的包含。本申请的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别不同对象，而不是用于描述特定顺序。
本实施方式提供的扭矩组件1是通过转动件13、滑动件14及第一弹性件16相互配合，从而实现悬停、自紧的结构。也可以理解为，转动件13可相对滑动件14固定不动。并且，本实施方式提供的扭矩组件1还可以与各种各样的部件配合，带动其他部件实现悬停、自紧。本实施方式仅以扭矩组件1应用于电子设备来进行示意说明。电子设备包括但不限于手机、平板、智能手表等。但这并不代表本实施方式的扭矩组件1一定要应用于电子设备中。在其他实施方式中，扭矩组件1也可以应用于其他领域，例如门锁领域、车辆领域等。
本实施方式提供的扭矩组件1包括转轴11，转轴11通常用于使其他部件套设在转轴11上以实现多个部件的装配，使多个部件相配合，为后续的转动与滑动提供基础。第一阻挡件12、转动件13、滑动件14、第二阻挡件15、及第一弹性件16均套设于转轴11，即转轴11贯穿第一阻挡件12、转动件13、滑动件14、第二阻挡件15、及第一弹性件16。转轴11的材料包括但不限于塑料、金属等，且本实施方 式对提供的转轴11的形状不进行限定，可以为任何形状的部件，仅需使转轴11贯穿第一阻挡件12、转动件13、滑动件14、第二阻挡件15、及第一弹性件16即可。关于转轴11的具体结构，本申请将在下文进行详细介绍。

进一步可选地，第一阻挡件12套设于转轴11上，也可以理解为第一阻挡件12具有通孔，转轴11贯穿该通孔，从而使第一阻挡件12连接转轴11，可选地，第一阻挡件12连接转轴11的方式包括但不限于固定连接、滑动连接等等。可选地，当第一阻挡件12滑动连接转轴11时，可在转轴11上设置其他结构件或者在转轴11自身上设置限位部等阻挡第一阻挡件12相对转轴11的滑动，从而限制转动件13的滑动。第一阻挡件12的材料包括但不限于塑料、金属等，且本实施方式对提供的第一阻挡件12不进行限定，可以为任何形状的部件，仅需第一阻挡件12可限定转动件13相对于转轴11的轴向滑动即可。本实施方式对第一阻挡件12与转轴11的结构形式并不进行限定。本实施方式仅以第一阻挡件12套设于转轴11上进行示意性说明。
转动件13通常用于进行转动。转动件13套设于转轴11，转动件13可相对于转轴11进行转动。并且，转动件13还可与其他部件例如滑动件14相配合，故转动件13也可带动其他相连的部件相对于滑动件14转动。转动件13设有第一配合部131，需要说明的是，在实际生产中，转动件13与第一配合部131是一体成型的结构件，但为方便理解，人为地将转动件13与第一配合部131进行了不同的命名。转动件13的材料包括但不限于塑料、金属等，且本实施方式对提供的转动件13不进行限定，可以为任何形状的部件，仅需设有第一配合部131即可。并且，本申请对第一配合部131的形状并不进行限定，只要第一配合部131与第二配合部141可相互配合即可。第一配合部131设于转动件13套设转轴11的部分，即第一配合部131对应着转轴11的外周缘进行设置，以使转动件13在转动至任意角度时均可以与其他部件进行配合。也可以理解为，第一配合部131具有通孔，转轴11贯穿该通孔。关于第一配合部131的结构，本申请将在下文进行详细介绍。
滑动件14套设于转轴11，且滑动件14可相对于转轴11轴向滑动。滑动件14设有第二配合部141，需要说明的是，在实际生产中，滑动件14与第二配合部141是一体成型的结构件，但为方便理解，人为地将滑动件14与第二配合部141进行了不同的命名。滑动件14的材料包括但不限于塑料、金属等，且本实施方式对提供的滑动件14不进行限定，可以为任何形状的部件，仅需设有第二配合部141即可。并且，本申请对第二配合部141的形状并不进行限定，只要第一配合部131与第二配合部141可相互配合即可。第二配合部141设于滑动件14套设转轴11的部分，以使第二配合部141也可相对于转轴11滑动。也可以理解为，第二配合部141具有通孔，转轴11贯穿该通孔。关于第二配合部141的结构，以及第一配合部131与第二配合部141具体的配合方式，本申请将在下文进行详细介绍。
另外，当转动件13相对滑动件14转动时，使滑动件14相对于转轴11滑动。可选地，当转动件13转动时，转动件13带着转轴11同步转动，即转动件13在转轴11的周向方向上相对静止；此时滑动件14在转轴11的周向方向上相对静止，仅在转轴11的轴向方向上相对滑动，即滑动件14不可相对转轴11转动，仅可相对转轴11滑动。在另一实施方式中，当转动件13转动时，转动件13在转轴11的周向方向上相对转动，即当转动件13转动时，转轴11静止不动；此时，滑动件14在转轴11的周向方向上相对静止，仅在转轴11的轴向方向上相对滑动，即滑动件14不可相对转轴11转动，仅可相对转轴11滑动。这两种运动状态均可使扭矩组件1实现悬停、自紧，关于这些部件之间具体的配合过程，本申请将在下文进行详细介绍。
第二阻挡件15通常也用于限制其他部件运动。第二阻挡件15固定转轴11，以实现第二阻挡件15相对与转轴11的位置保持固定不动。可选地，为了实现第二阻挡件15固定于转轴11，本实施方式提供了多种具体的实现方式。在一种实现方式中，第二阻挡件15与转轴11为一体式结构，即第二阻挡件15与转轴11是通过一道工序制备形成的，不过为了方便理解，人为地将第二阻挡件15与转轴11进行了不同地命名。在另一种实现方式中，第二阻挡件15与转轴11为分体式结构，即第二阻挡件15与转轴11是分别制备形成的，然后再通过各种方法装配到一起。
进一步可选地，第二阻挡件15套设于转轴11上，也可以理解为第二阻挡件15具有通孔，转轴11贯穿该通孔，从而使第二阻挡件15连接转轴11，可选地，第二阻挡件15连接转轴11的方式也包括但不限于固定连接、滑动连接等等。可选地，当第二阻挡件15滑动连接转轴11时，可在转轴11上设置其他结构件或者在转轴11自身上设置限位部等阻挡第二阻挡件15相对转轴11的滑动，从而限制第一弹性件16的滑动。第二阻挡件15的材料包括但不限于塑料、金属等，且本实施方式对提供的第二阻挡件15不进行限定，可以为任何形状的部件，仅需第二阻挡件15可限定第一弹性件16相对于转轴11的轴向滑动即可。本实施方式对第二阻挡件15与转轴11的结构形式并不进行限定。本实施方式仅以第二阻挡件15套设于转轴11上进行示意性说明。
需要说明的是，第一阻挡件12、转动件13、滑动件14、第二阻挡件15、及第一弹性件16均可套设于转轴11，实现装配，并为后续的转动与滑动提供基础。也可以理解为，第一阻挡件12、转动件13、滑动件14、及第二阻挡件15均设有相对应的通孔，转轴11依次贯穿相对应的通孔。
并且，第一阻挡件12与第二阻挡件15相对于转轴11的位置不同，故第一阻挡件12与第二阻挡件15限制的部件不同。在本实施方式中，通过在转动件13的一侧设置第一阻挡件12，来限制转动件13朝向第一阻挡件12方向的滑动，同样通过在第一弹性件16的一侧设置第二阻挡件15，来限制第一弹性件16朝向第二阻挡件15方向的滑动。第一阻挡件12与第二阻挡件15分别设于转动件13、滑动件14、及第一弹性件16的两端，故第一阻挡件12与第二阻挡件15可限制转动件13、滑动件14、及第一弹性件16的滑动范围，使其只能在第一阻挡件12与第二阻挡件15之间滑动。并且滑动范围的限制，更有利于后续第一弹性件16的形变，使其具有弹性力的产生。
第一弹性件16设于滑动件14与第二阻挡件15之间。可选地，第一弹性件16可与滑动件14、及第二阻挡件15相接触，也可以不与滑动件14、及第二阻挡件15相接触，仅需当滑动件14相对转轴11滑动时，第一弹性件16可与滑动件14、及第二阻挡件15相连接，且处于压缩状态即可。更进一步可选地，第一弹性件16与滑动件14、及第二阻挡件15的连接方式包括但不限于抵接、固定连接、可拆卸连接、粘接等等。第一弹性件16可以为螺旋弹簧、涡卷弹簧、板弹簧、碟形弹簧等。当然在其他实施方式中第一弹性件16也可以为其他具有弹性的物体，例如弹性泡棉、海绵、由各种高分子材料制成的制品等等。
从上述内容可知，当第一配合部131与第二配合部141相互配合时，可将转动件13相对于滑动件14的转动转换为滑动件14相对于转轴11的滑动。当滑动件14相对转轴11朝向远离转动件13的方向滑动时，由于第一弹性件16的另一端设有第二阻挡件15，限制第一弹性件16的滑动范围，从而使第一弹性件16可与滑动件14、及第二阻挡件15相连接，且滑动件14压缩第一弹性件16，使第一弹性件16处于压缩状态。
需要进一步说明的是，当滑动件14朝向远离转动件13的方向滑动时，可使第一弹性件16处于压缩状态。但是，当转动件13还未相对滑动件14转动，即第一弹性件16处于初始状态时，本实施方式并不限定第一弹性件16的初始状态，第一弹性件16的初始状态包括但不限于拉伸状态、平衡状态、或者已经处于压缩状态。
在另一种实施方式中，第一弹性件16具有预压缩状态。也可以理解为所述第一弹性件16以预压缩状态介于所述滑动件14与所述第二阻挡件15之间。这里提及的“预压缩状态”指的就是当转动件13未转动时，即第一弹性件16的初始状态便已经处于压缩状态。也可以理解为，当第一配合部131与第 二配合部141未配合，即滑动件14未朝向靠近或远离转动件13的方向滑动时，第一弹性件16已处于压缩状态。具有预压缩状态的第一弹性件16可补偿第一弹性件16相对于转轴11的轴向运动，也可以理解为，当扭矩组件1使用一段时间后，即使第一弹性件16的尺寸发生变化或者结构松动，具有预压缩状态的第一弹性件16也可补偿第一弹性件16相对于转轴11的轴向运动，从而提高驱动组件的稳定性，确保驱动组件中扭力手感长期的一致性。
如图1所示，通过在转动件13上设置第一配合部131、滑动件14上设置第二配合部141、及第一弹性件16，通过三者的配合，当转动件13相对滑动件14(如图1中D2方向所示)转动时，第一配合部131与第二配合部141相互配合可使滑动件14朝向靠近或远离转动件13的方向(如图1中D1方向所示)滑动。也可以理解为，当转动件13相对于滑动件14转动时，第一配合部131也相对第二配合部141转动，由于第一配合部131与第二配合部141可相互配合，从而使滑动件14朝向靠近或远离转动件13的方向滑动。
并且，当滑动件14朝向靠近或远离转动件13的方向(如图1中D1方向所示)滑动时，滑动件14会接触并压缩第一弹性件16，此时处于压缩状态的第一弹性件16给予滑动件14反弹力，从而使滑动件14紧密抵接转动件13。同时，第一弹性件16给予的反弹力(如图1中F1所示)可转化成滑动件14给予转动件13一定的压力(如图1中F1所示)。由于转动件13与滑动件14之间的摩擦力与压力呈正相关，即正压力越大，摩擦力越大。当摩擦力大于预设值，且转动件13停止转动时，转动件13不会相对转轴11转动，滑动件14与转动件13固定不动，即转动件13处于稳定状态。稳定状态是指当转动件13停止转动时，转动件13不会由于自身重力、外力等原因，相对滑动件14回转，从而掉落的状态。也可以理解为，在第一弹性件16反弹力的作用下，滑动件14给予转动件13额外的压力，使转动件13与滑动件14之间的摩擦力大于预设值时，滑动件14不会相对于转动件13转动，从而固定转动件13，使转动件13实现悬停、自紧等功能。其中，预设值可以为转动件13的重力、或者转动件13受到的推力、拉力等额外的力。例如，当转动件13的延伸方向与重力的方向相平行时，预设值可以为转动件13自身的重力；当转动件13的延伸方向与重力的方向相交错时，预设值可以为转动件13受到的推力、拉力、转动件13自身重力等。
另外，若想使转动件13继续转动，需要提供大于预设力的力以使转动件13从相对滑动件14静止的状态转变为相对滑动件14转动的状态。此时该力的一部分用于抵消上述过程产生的摩擦力，而剩余的部分则用于使转动件13继续转动。当提供大于预设力的外力后，可使转动件13继续转动，且滑动件14由朝向远离转动件13的方向转为靠近转动件13的方向滑动。当滑动件14朝向靠近转动件13的方向滑动、且第一弹性件16处于压缩状态时，由于此时第一弹性件16正在回复形变，第一弹性件16的反弹力减小，因此由第一弹性件16提供的压力减小，滑动件14对转动件13的摩擦力减小，此时只需要更小的力即可使转动件13转动，故使转动件13更容易转动，且在第一弹性件16反弹力的作用下，滑动件14加速朝向靠近转动件13的方向滑动，为下一次扭矩组件1的悬停做准备。
需要说明的是，扭矩组件1提供的扭矩与摩擦力有关，而在转动件13转动的过程中，摩擦力随着滑动件14相对于转轴11的滑动而改变。也可以理解为，随着滑动件14改变第一弹性件16的状态，扭矩组件1提供的扭矩可变大或者变小。
综上，相较于相关技术中只使用凸轮实现悬停功能的结构，本实施方式通过设置第一配合部131、第二配合部141及第一弹性件16的相互配合，可提供更大的摩擦力，提高了摩擦性能，在使转动件13实现悬停、自紧等功能的同时，提高了悬停、自紧效果。换句话说，当需要提供同等的摩擦力大小时，本实施方式的扭矩组件1的尺寸更小，提高了扭矩组件1结构的紧凑性。
接下来介绍关于第一配合部131与第二配合部141的具体结构。请参考图3-图4，图3为本申请一实施方式中第一配合部与第二配合部的配合示意图。图4为本申请另一实施方式中第一配合部与第二配合部的配合示意图。本实施方式中，第一配合部131包括间隔设置的多个第一凸起131a，第二配合部141包括间隔设置的多个第二凸起141a，第一凸起131a与第二凸起141a均具有波峰，其中波峰是指凸 起的最高点。当然除了波峰外，第一凸起131a与第二凸起141a还具有波谷、及斜面，其中波谷是指凸起的最低点，斜面是指波峰与波谷之间的侧面。
当滑动件14朝向远离转动件13的方向滑动，且第一凸起131a的波峰与第二凸起141a的波峰相接触时，第一弹性件16处于压缩状态且使滑动件14抵接转动件13；当转动件13停止转动时，使得转动件13固定不动。本实施方式对提供的第一凸起131a与第二凸起141a不进行限定，可以为任何形状的部件，仅需第一凸起131a与第二凸起141a可相互配合即可。在本实施方式中，第一配合部131也可以理解为第一凸起131a部，第二配合部141也可以理解为第二凸起141a部。
可选地，首先，当转动件13未相对于滑动件14转动时，第一凸起131a与第二凸起141a的配合状态为波峰与波谷相对。然后，当转动件13相对于滑动件14转动时，第一凸起131a与第二凸起141a的配合状态为波峰沿着斜面滑动，直至波峰与波峰相对，此时滑动件14相对于转动件13之间的间距最大，相应地，此时第一弹性件16的压缩程度更明显，可提供更大的反弹力，从而进一步提高扭矩组件1的摩擦性能，提高悬停、自紧效果。接着，当转动件13在外力的作用下继续相对于滑动件14转动时，第一凸起131a与第二凸起141a的配合状态为波峰继续沿着斜面滑动，直至波峰与波谷相对，在这个过程中滑动件14相对于转动件13之间的间距逐渐减小，相应地，此时第一弹性件16的压缩程度减弱，可提供的反弹力减小，由于摩擦力减小，使转动件13更容易转动。最终，第一凸起131a与第二凸起141a将重复上述运动，为下一次扭矩组件1的悬停做准备。
由于当波峰与波峰相对时，扭矩组件1可实现悬停、自紧，因此凸起的数量、位置、及大小可决定悬停的角度。例如，当第一配合部131的第一凸起131a为6个，且第一凸起131a均匀间隔分布时，转动件13相对于滑动件14每转动60°，扭矩组件1可实现悬停。可选地，第一凸起131a的凸起数等于预设凸起数，第二凸起141a与第一凸起131a对应设置，以使扭矩结构可在预设转动范围内任意调节。
如图3与图4所示，本实施方式中，首先，当转动件13相对滑动件14转动时，第一凸起131a相对第二凸起141a转动，由于此时第二凸起141a既可相对于第一凸起131a转动，又可相对转轴11滑动，故滑动件14朝向靠近或远离转动件13的方向滑动。第一配合部131与第二配合部141具有两种配合状态，如图3所示，第一种状态为当第二凸起141a的波峰朝向靠近第一凸起131a的波峰的方向(如图3中D3方向所示)转动时，滑动件14朝向远离转动件13的方向(如图3中D4方向所示)滑动；第二种状态为当第二凸起141a的波峰朝向靠近第一凸起131a的波谷的方向(如图4中D5方向所示)转动时，滑动件14朝向靠近转动件13的方向(如图4中D6方向所示)滑动。
其次，当滑动件14朝向远离转动件13的方向滑动，且第一凸起131a的波峰与第二凸起141a的波峰相接触时，滑动件14抵接第一弹性件16，此时第一弹性件16处于压缩状态，第一弹性件16提供的反弹力转化为压力，使滑动件14抵接转动件13；当转动件13停止转动，且第一弹性件16反弹力转化的压力使转动件13与滑动件14之间的摩擦力大于预设值时，滑动件14不会相对于转动件13转动，从而固定转动件13，使转动件13实现悬停、自紧等功能。因此，本实施方式可通过设置第一凸起131a、第二凸起141a及第一弹性件16配合，实现悬停功能，从而使扭矩组件1的尺寸更小，提高了扭矩组件1结构的紧凑性。
接下来介绍关于转轴11的具体结构。请一并参考图5-图7，图5为本申请一实施方式中转轴的立体结构示意图。图6为本申请又一实施方式中扭矩组件的立体结构示意图。图7为本申请又一实施方式图6中的爆炸图。本实施方式中，转轴11的至少部分外周侧设有扁位结构111，扭矩组件1还包括摩擦件17，摩擦件17与转动件13均套设于转轴11的扁位结构111处，且摩擦件17位于第二阻挡件15背离第一阻挡件12的一侧。当转动件13转动时可带动转轴11与摩擦件17转动。
摩擦件17通常用于提供摩擦力。并且，摩擦件17的材料包括但不限于塑料、金属等具有高摩擦系数的材料，且本实施方式对提供的摩擦件17不进行限定，可以为任何形状的部件，仅需可提供弹性件的摩擦力即可。摩擦件17套设于转轴11，即摩擦件17具有通孔，转轴11贯穿该通孔。
上述提及的“扁位结构”指的是转轴11的周向的形状若为圆形，则套设于转轴11的结构件难与转 轴11进行固定，因此可通过各种工艺(例如铣削加工)将圆形加工成其他形状从而在转动件的转动过程中实现固定或者夹紧。因此扁位结构可以为理解为形状为非圆形的结构。可选地，扁位结构在周向的形状为正方形、长方形、椭圆形等等。可选地，扁位结构111由圆柱形的转轴11开设限位槽111a形成，从而使至少部分圆柱形的转轴11变为椭圆形或者类长方形。扁位结构111用于限定其他部件的周向运动，使其他部件与转轴11相对静止，即转轴11转动时也会带动其他部件一同转动。本实施方式对提供的扁位结构111不进行限定，可以为任何形状的部件，仅需可限定其他部件的径向运动即可。需要说明的是，在实际生产中，转轴11与扁位结构111是一体成型的结构件，但为方便理解，人为地将转轴11与扁位结构111进行了不同的命名。
在本实施方式中，摩擦件17与转动件13均套设于转轴11的扁位结构111处。可以理解为，摩擦件17与转动件13的通孔形状与扁位结构111相对应，以使摩擦件17与转动件13固定于转轴11上，即当转轴11转动时，摩擦件17与转轴11相对静止，且转动件13与转轴11相对静止。可选地，限位槽111a的底壁均具有加工槽，加工槽用于加工定位，便于加工扁位结构111。
如图7所示，由于转动件13与摩擦件17均具有与扁位结构111形状相似的通孔，可使摩擦件17与转轴11相对静止；转动件13与转轴11相对静止。因此，当转动件13转动时，由于扁位结构111与转动件13、及摩擦件17相互配合，转动件13带动转轴11、及摩擦件17同步转动。需要说明的是，由于滑动件14通孔的形状为圆形，与扁位结构111的形状不匹配，即滑动件14与扁位结构111之间具有间隙，故滑动件14可相对转轴11、转动件13及摩擦件17转动，以实现进一步的滑动。由于摩擦件17设于第二阻挡件15的一侧，当摩擦件17随着转轴11同步转动时，摩擦件17将与第二阻挡件15相向摩擦，从而产生周向的摩擦力。当第一弹性件16的一端给予滑动件14反弹力时，第一弹性件16的另一端也给予第二阻挡件15反弹力，从而使第二阻挡件15给予摩擦件17压力。随着第一弹性件16压缩程度增加，压力不断增加，因此周向摩擦力也不断增加，可进一步提高扭矩组件1的悬停、自紧效果，使本实施方式的扭矩组件1的尺寸可进一步减少，从而进一步提高扭矩组件1结构的紧凑性。
请参考图8，图8为本申请又一实施方式中扭矩组件的立体结构示意图。本实施方式中，扭矩组件1还包括安装件18，安装件18套设于转轴11，安装件18位于第二阻挡件15背离第一阻挡件12的一侧；扭矩组件1包括两个摩擦件17，一个摩擦件17位于第二阻挡件15与安装件18之间，另一个摩擦件17位于安装件18背离第一阻挡件12的一侧。
安装件18通常用于使扭矩组件1与其他部件连接，用于装配等。安装件18的材料包括但不限于塑料、金属等，且本实施方式对提供的安装件18不进行限定，可以为任何形状的部件，仅需可使扭矩组件1与其他部件连接即可。可选地，本实施方式的安装件18具有安装孔。其他部件可利用安装孔与扭矩组件1进行连接。进一步可选地，扭矩组件1与其他部件连接的连接方式包括但不限于使用螺钉、转轴11、粘结剂连接等等。
如图8所示，通过设置安装件18及两个摩擦件17，不仅可以使扭矩组件1便于与其他部件连接，提高扭矩组件1的连接性能，而且可进一步增加提供的摩擦力，使本实施方式的扭矩组件1的尺寸可进一步减少，从而进一步提高扭矩组件1结构的紧凑性。并且，由于安装件18设于两个摩擦件17之间，两个摩擦件17可与扁位结构111相配合，使摩擦件17固定于转轴11上，且当转轴11转动时，两个摩擦件17与转轴11相对静止。在本实施方式中，转轴11贯穿安装件18的通孔为圆形。当转轴11转动时，转轴11可带动两个摩擦件17相对安装件18、第二阻挡件15转动，从而随着第一弹性件16压缩程度的增加，产生更多周向的摩擦力，进一步提高扭矩组件1的悬停效果。
请再次参考图5与图9，图9为本申请又一实施方式中扭矩组件的立体结构示意图。本实施方式中，转轴11在摩擦件17背离第一阻挡件12的一端的周侧设有卡扣槽112，扭矩组件1还包括卡扣件19，且部分卡扣件19设于卡扣槽112内。
卡扣件19通常用于限制其他部件的运动。卡扣件19套设于转轴11，卡扣件19位于摩擦件17背离第一阻挡件12的一侧。卡扣件19套设转轴11，即卡扣件19具有通孔，转轴11贯穿该通孔。卡扣件 19的材料包括但不限于塑料、金属等，且本实施方式对提供的卡扣件19不进行限定，可以为任何形状的部件，仅需可限制其他部件的运动即可。可选地，卡扣件19可为轴卡。
如图9所示，本实施方式的卡扣件19设于卡扣槽112内，且位于摩擦件17背离第一阻挡件12的一侧，故卡扣件19可进一步限制第二阻挡件15与摩擦件17相对于转轴11的轴向滑动。因此，通过利用第一阻挡件12、第二阻挡件15、及卡扣件19同时限定转动件13、滑动件14、第一弹性件16、及摩擦件17在转轴11上的轴向滑动，从而进一步提高扭矩组件1的稳定性能。
请参考图10，图10为本申请一实施方式中转轴套件的立体结构示意图。转轴套件2包括两个如本申请提供的扭矩组件1，两个扭矩组件1呈轴对称设置，且其中一个扭矩组件1中的转动件13朝向远离另一个扭矩组件中1的转动件13的方向延伸设置。
本实施方式的转轴套件3包括两个扭矩组件1，扭矩组件1在上文已经进行了详细的描述，在此不再赘述。两个扭矩组件1呈轴对称设置，也可以理解为两个扭矩组件1沿着转轴11的轴向对称设置。由于轴对称设置，使两个转轴11相邻设置，可减小转轴套件3的尺寸。转轴套件3可使两个转动件13相对转动，也可以理解为使两个转动件13朝向互相靠近或者互相远离的方向运动。
并且，转轴套件3中的一个转动件13朝向远离另一个转动件13的方向延伸设置，使两个转动件13在同步转动时，同时朝向互相远离转轴11的方向或者互相靠近转轴11的方向运动，即使两个转动件13相背转动或者相向转动，从而避免两个转动件13同向转动。
如图10所示，本实施方式提供的转轴套件3，通过使用本实施方式提供的扭矩组件1，可通过第一弹性件16来提供压力进而提供摩擦力，故相较于相关技术，不仅可提高悬停、自紧效果，而且当需提供同样的摩擦力实现悬停时，本实施方式中的转轴套件3可采用更小的尺寸，提高了转轴套件3结构的紧凑性。并且，由于采用更小尺寸的扭矩组件1，使转轴套件3中两个扭矩组件1间的间隙更小。也可以理解为，通过采用更小尺寸的扭矩组件1，可减小转轴套件3的弯折半径，从而使弯折后两个转动件13之间的缝隙更小。
请参考图11，图11为本申请另一实施方式中转轴套件的立体结构示意图。本实施方式中，两个扭矩组件1中的两个滑动件14相互连接。
本实施方式的转轴套件3中两个滑动件14相互连接，滑动件14在上文已经进行了详细的描述，本申请在此不再赘述。可选地，本申请对两个滑动件14的连接方式不进行限定，其连接方式包括但不限于固定连接、卡扣连接等等。更进一步可选地，本实施方式中两个滑动件14的连接方式为固定连接；两个滑动件14还可以一体地形成。
如图11所示，由于两个滑动件14相互连接，当一个滑动件14朝向靠近或远离转动件13的方向(如图11中D1方向所示)滑动时，另一个滑动件14也同时朝向靠近或远离转动件13的方向(如图11中D1方向所示)滑动，降低了转动件13的转动难度，并使两个第一弹性件16提供的反弹力转化为摩擦力，使两个转动件13悬停、自紧。因此，本实施方式的转轴套件3可采用更小的尺寸，提高了转轴套件3结构的紧凑性，以及通过两个滑动件14连接配合，可提高扭力平衡。
请参考图12，图12为本申请又一实施方式中转轴套件的立体结构示意图。本实施方式中，两个扭矩组件1中的两个第二阻挡件15相互连接，转轴套件3还包括定位件21与第二弹性件22，定位件21位于滑动件14与第二阻挡件15之间，且定位件21连接于两个滑动件14的连接处、或两个第二阻挡件15的连接处；第二弹性件22套设定位件21，且第二弹性件22的相对两端分别与两个滑动件14的连接处、及两个第二阻挡件15的连接处相接触。
本实施方式中两个第二阻挡件15相互连接，另外关于第二阻挡件15在上文已经进行了详细的描述，本申请在此不再赘述。可选地，本申请对两个第二阻挡件15的连接方式不进行限定，其连接方式包括但不限于固定连接、卡扣连接等等。更进一步可选地，本实施方式中两个第二阻挡件15的连接方式为固定连接；两个第二阻挡件15还可以一体地形成。
定位件21设于两个滑动件14连接处、及两个第二阻挡件15连接处之间，用于限定第二弹性件22 的位置，使当滑动件14朝向靠近或远离转动件13的方向滑动时，第二弹性件22与第一弹性件16同时发生形变。需要说明的是，一个扭矩组件1中的一个滑动件14使一个第一弹性件16发生形变，另一个扭矩组件1中的另一个滑动件14使另一个第一弹性件16变形。并且，两个滑动件14的连接处使第二弹性件22发生形变。定位件21的材料包括但不限于塑料、金属等，且本实施方式对提供的定位件21不进行限定，可以为任何形状的部件，仅需可使定位件21限定第二弹性件22的位置即可。可选地，本实施方式中的定位件21为与第二弹性件22对应的圆柱体。需要说明的是，定位件21、滑动件14、及第二阻挡件15可以为一体成型的结构件，也可以为分别独立成型，再进行装配的结构件。
可选地，第二弹性件22具有预压缩状态。预压缩状态在上文已经进行了详细的描述，本申请在此不再赘述。
如图12所示，当滑动件14朝向靠近或远离转动件13的方向(如图12中D1方向所示)滑动时，第二弹性件22与第一弹性件16同时发生形变。也可以理解为，当第一配合部131与第二配合部141相互配合时，可使第一弹性件16与第二弹性件22同时处于压缩状态，从而提高弹性件给予滑动件14的压力，从而提高转动件13与滑动件14之间的摩擦力，使本实施方式的转轴套件3的尺寸可进一步减少，从而进一步提高转轴套件3结构的紧凑性。
可选地，请参考图13，图13为本申请又一实施方式中转轴套件的立体结构示意图。本实施方式中，两个扭矩组件1中的两个第一阻挡件12相互连接。更近一步可选地，两个扭矩组件1中的两个安装件18相互连接，从而进一步提高转轴套件3各部件之间的连接性能，进一步提高扭力平衡。当在其他实施方式中，两个扭矩组件1也可以仅设置一个安装件18，分别连接于两个扭矩组件1。故既可以进一步提高转轴套件3各部件之间的连接性能，进一步提高扭力平衡；又可以便于安装件18与扭矩组件1之间的拆卸与安装。
请一并参考图14-图15，图14为本申请一实施方式中转轴套件的立体结构示意图。图15为本申请一实施方式图14中的爆炸图。转轴套件3包括基座31，两个传动件32，以及如本申请提供的转轴套件3。其中，基座31上设有两个转动空间31a。一个传动件32的部分设于一个转动空间31a内，另一个传动件32的部分设于另一个转动空间31a内，两个传动件32均能够相对于基座31转动。两个扭矩组件1中的两个转轴11连接于基座31，一个扭矩组件1中的转动件13连接于一个传动件32，另一个扭矩组件1中的转动件13连接于另一个传动件32。当传动件32相对基座31转动时能够带动转动件13转动。
基座31通常用于承载、连接其他部件等。基座31的材料包括但不限于塑料、金属等，且本实施方式对提供的基座31不进行限定，可以为任何形状的部件，仅需基座31设有转动空间31a，可与传动件32配合转动即可。需要说明的是，在实际生产中，基座31与转动空间31a是一体成型的结构件，例如基座31的材质为塑料，在制备基座31的过程中可利用注塑成型等方法直接制备出具有转动空间31a的基座31。关于转动空间31a与传动件32配合的具体结构，本申请将在下文进行详细介绍。
传动件32通常与其他部件相连接，可带动其他部件运动。传动件32的材料包括但不限于塑料、金属等，且本实施方式对提供的传动件32不进行限定，可以为任何形状的部件，仅需传动件32可相对基座31转动，且与转动件13连接即可。可选地，传动件32设有多个通孔。通孔用于使传动件32与其他部件相连接，例如用螺钉可拆卸连接于其他部件上。当传动件32相对基座31转动时，与传动件32连接的其他部件(例如电子设备的壳体41)也相对基座31转动。关于传动件32与转动件13连接的具体结构，本申请将在下文进行详细介绍。
如图14所示，当传动件32相对于基座31转动(如图14中D2方向所示)时，由于传动件32与转动件13相连接，传动件32可带动转动件13同时转动。若此时传动件32停止转动，即转动件13也停止转动，且由第一弹性件16提供的压力转换的摩擦力大于预设值时，转动件13相对滑动件14固定，从而使传动件32也相对滑动件14固定，实现转轴套件3悬停、自紧。并且，由于采用更小尺寸的扭矩组件1，使转轴套件3中两个扭矩组件1间的间隙更小。也可以理解为，通过采用更小尺寸的扭矩组件1，可减小转轴套件3的弯折半径，从而使弯折后两个传动件32之间的缝隙更小。另外，若传动件32 与其他部件相连接，可通过传动件32带动其他部件转动；或者使其他部件悬停、自紧。
因此，本实施方式的转轴套件3，不仅通过设置传动件32，可使传动件32与其他部件相连接，提高转轴套件3的连接性能，而且通过使用本申请提供的转轴套件3，可通过第一弹性件16来提供压力进而提供摩擦力。故相较于相关技术，不仅可提高悬停、自紧效果，而且当需提供同样的摩擦力实现悬停时，本申请转轴套件3可采用更小的尺寸，提高了转轴套件3结构的紧凑性。同时，由于可采用更小的转轴套件3，既可进一步减小基座31、传动件32的尺寸，从而进一步减小了转轴套件3的尺寸，又可减小转轴套件3的弯折半径，从而使弯折后两个传动件32之间的缝隙更小。当本实施方式提供的转轴套件3应用于柔性屏手机中时，当柔性屏手机折叠时，可减小柔性屏的弯折半径，降低两半柔性屏之间的距离，从而提高柔性屏手机的外观性能。
可选地，当两个传动件32水平展开、且呈180°时，沿传动件32的延伸方向，相关技术中的转轴套件的尺寸至少为30mm，而本申请的转轴套件3的尺寸可减少至25mm以下。因此，从上述测试结果中可以看出，本申请提供的转轴套件3的尺寸相较于相关技术中的转轴套件3的尺寸来说，尺寸可降低16.7％以上。
请再次参考图15，本实施方式中，一个传动件32靠近另一个传动件32的一侧设有避让槽323，另一个传动件32的部分设于避让槽323内。如图15所示，一个避让槽323的形状与另一个传动件32相对设置，以使另一个传动件32的至少部分设于避让槽323内。因此，可通过设置避让槽323，使传动件32的至少部分设于避让槽323，进一步减小传动件32的尺寸，从而进一步减小了转轴套件3的尺寸。
请参考图16-图17，图16为本申请另一实施方式中转轴套件的第一转动中心与第二转动中心示意图。图17为本申请另一实施方式中图16中的局部放大图。本实施方式中，传动件能够绕第一轴线L1转动，转动件能够绕第二轴线L2转动，第一轴线与第二轴线平行且彼此间隔开；当转动件转动时，转动件还相对传动件滑动。
本实施方式中，传动件能够绕第一轴线L1转动，转动件能够绕第二轴线L2转动。且传动件32具有第一转动中心O1，转动件13具有第二转动中心O2。其中，轴线是指转动中心沿轴向的延伸线，且轴线垂直于转动方向。并且，第一轴线L1与第二轴线L2之间具有间距H1。也可以理解为，在平行于传动件32的转动方向上，第一转动中心O1与第二转动中心O2之间具有间距H1。由于传动件32的第一转动中心与转动空间31a有关，转动件13的第二转动中心与转轴11有关，转动空间31a与转轴11的中心轴之间具有间隙。
如图16所示，本实施方式通过设置第一轴线L1与第二轴线L2之间具有间距H1，图16中转动中心外周的圆形虚线表示分别传动件32、转动件13上相应部分的转动轨迹，且传动件32、转动件13对应的转动中心以实心小黑点表示。虽然在本实施方式中仅以第一转动中心O1与第二转动中心O2示意说明，但由于第一轴线L1为第一转动中心O1沿轴向的延伸线，第二轴线L2为第二转动中心O2沿轴向的延伸线，故第一轴线L1与第二轴线L2之间的间距H1与第一转动中心O1与第二转动中心O2之间在平行于传动件32的转动方向上的间距H1相等。若在平行于传动件32的转动方向上，第一转动中心与第二转动中心的转动中心可重叠，而导致传动件32的尺寸较大。本实施方式使第一轴线L1与第二轴线L2之间具有间距H1，可避免将第一转动中心与第二转动中心对应设置，从而进一步减小了转轴套件3的尺寸，进一步提高转轴套件3结构的紧凑性。
另外，传动件32可带动转动件13转动，由于第一转动中心与第二转动中心之间具有间距，故当传动件32带动转动件13转动时，转动件13需通过相对传动件32滑动，以补偿第一转动中心与第二转动中心之间的间隙(如图16中H1所示)产生的位移偏差，从而使当转动件13与传动件32同时转动时，防止转动件13与传动件32相互卡死，以确保转轴套件3工作的稳定性。
接下来对关于转动件13相对传动件32滑动的具体结构，进行详细介绍。请参考图15与图18，图18为本申请又一实施方式中转轴套件的立体结构示意图。本实施方式中，转动件32靠近传动件的一端设有第一滑动部351，传动件32靠近转动件13的一端设有第二滑动部321，第一滑动部351与第二滑 动部321相互配合以使转动件13相对传动件32滑动。本实施方式对第一滑动部351与第二滑动部321的形状不进行限定，仅需第一滑动部351可与第二滑动部321配合，使转动件13相对传动件32滑动即可。
接下来，将对第一滑动部351与第二滑动部321的三种具体的结构进行一一介绍。
在一种实施方式中，转动件13设有开孔132，转轴套件3还包括辅助件35，辅助件35贯穿开孔132；辅助件35靠近传动件32的一端设有第一滑动部351，传动件32靠近转动件13的一端设有第二滑动部321，第一滑动部351与第二滑动部321相互配合以使转动件13相对传动件32滑动。
辅助件35用于连接传动件32与转动件13，使转动件13可相对传动件32滑动。辅助件35贯穿开孔132，即至少部分辅助件35设于开孔132内。辅助件35的材料包括但不限于塑料、金属等，且本实施方式对提供的辅助件35不进行限定，可以为任何形状的部件，仅需可辅助件35连接转动件13，且设有与第二滑动部321对应的第一滑动部351即可。并且，本实施方式对提供的开孔132不进行限定，可以为任何形状的部件，仅需可与辅助件35相配合即可。可选地，辅助件35与第一滑动部351是一体成型的结构件，即辅助件35与第一滑动部351是通过一道工序制备而成，但为方便理解，人为地将辅助件35与第一滑动部351进行了不同的命名。当然在其他实施方式中，辅助件35与第一滑动部351也可以为分体式结构。即辅助件35与第一滑动部351分别制备而成，然后再通过各种各样的方法装配到一起。本实施方式在此并不限定辅助件35与第一滑动部351的关系。关于第一滑动部351与第二滑动部321的具体结构，本申请将在下文进行详细介绍。
如图18所示，当传动件32带动转动件13转动时，第一滑动部351与第二滑动部321相配合，使转动件13同时相对传动件32滑动，以补偿第一转动中心与第二转动中心之间的间隙产生的位移偏差。当传动件32、及转动件13停止转动时，第一滑动部351与第二滑动部321仍保持配合，且辅助件35相对传动件32固定不动，以使转轴套件3实现悬停。因此，本实施方式可通过设置贯穿转动件13的辅助件35，且使辅助件35的第一滑动部351与传动件32的第二滑动部321配合，保证第一滑动部351与第二滑动部321的正常滑动，防止转动件13与传动件32出现卡死等问题，以确保转轴套件3工作的稳定性。
在另一种实施方式中，请参考图19，图19为本申请又一实施方式中第一滑动部与第二滑动部相配合的示意图。本实施方式中，第一滑动部351为滑块351a，第二滑动部321为滑槽321a，且转动件13相对传动件32滑动时，辅助件35相对转动件13静止。如图19所示，当第一滑动部351与第二滑动部321相配合时，至少部分滑块351a设于滑槽321a内。需要说明的是，当转动件13相对传动件32滑动时，滑块351a沿滑槽321a相对传动件32滑动；当转动件13、及传动件32停止转动时，滑块351a相对滑槽321a固定不动。这两种状态时，至少部分滑块351a均始终设于滑槽321a内。需要进一步说明的是，滑槽321a的延伸方向与传动件32的延伸方向呈现第一夹角A，本申请对第一夹角的角度并不进行限定，只需第一滑动部351可与第二滑动部321配合即可。通过设置第一夹角，可补偿第一转动中心与第二转动中心之间的间隙产生的位移偏差，使传动件32与滑动件14转动时的延伸方向互相平行。可选地，本实施方式的第一倾斜角不大于90°。因此，本实施方式可通过设置滑槽321a与滑块351a，使辅助件35的第一滑动部351与传动件32的第二滑动部321配合，保证第一滑动部351与第二滑动部321的正常滑动，防止转动件13与传动件32出现卡死等问题，以确保转轴套件3工作的稳定性。
第一种辅助件35与开孔132的连接方式请参考图20，图20为本申请又一实施方式中转轴套件的第一干涉部与第二干涉部的立体结构示意图。
在相关技术中，通常通过设置额外的限位结构使辅助件35固定连接于转动件13上，额外的限位结构会导转轴套件3的尺寸较大。例如采用卡簧限位时，需要在辅助件35上开设直径较小的卡簧槽，且同时为了确保辅助件35的硬件强度，通常需要增加辅助件35的尺寸，从而导致转轴套件3的尺寸较大，且额外的限位结构使组装成本及生产成本进一步增加。
本实施方式中，转动件13设有开孔132以用于安装辅助件35，辅助件35的外周侧设有第一干涉部 352，开孔的内壁设有第二干涉部1321，第一干涉部352与第二干涉部1321相互配合。
转动件13靠近传动件32的一侧设有开孔132。其中这里提及的“开孔132”可以理解为贯穿转动件13相对两侧的通孔，此时辅助件35可贯穿该开孔132。或者开孔132为贯穿转动件13靠近传动件32一侧的凹槽，也可称之为盲孔，部分辅助件35设于开孔132内，其余的辅助件35露出以用来和传动件32上的第二滑动部321滑动配合。
可选地，位于开孔132内的辅助件35的外周侧设有第一干涉部352，开孔132的侧壁设有第二干涉部1321，第一干涉部352与第二干涉部1321相互配合，以使辅助件35相对转动件13静止。本实施方式对提供的第一干涉部352与第二干涉部1321不进行限定，可以为任何形状的部件，仅需第一干涉部352与第二干涉部1321对应设置即可。需要说明的是，在实际生产中，辅助件35与第一干涉部352是一体成型的结构件，但为方便理解，人为地将辅助件35与第一干涉部352进行了不同的命名。同样地，在实际生产中，开孔132与第二干涉部1321是一体成型的结构件，但为方便理解，人为地将开孔132与第二干涉部1321进行了不同的命名。
可选地，第一干涉部352具有多个间隔分布的第三凸起352a，第二干涉部1321具有多个与第三凸起352a对应设置的干涉槽1321a，或者当第二干涉部1321具有多个间隔分布的第三凸起352a时，第一干涉部352具有多个与第三凸起352a对应设置的干涉槽1321a。
如图20所示，当第一滑动部351与第二滑动部321相配合时，第一干涉部352始终与第二干涉部1321配合，即第一干涉部352相对第二干涉部1321固定不动，使辅助件35相对转动件13静止。需要说明的是，当滑块351a沿滑槽321a相对传动件32滑动时，第一干涉部352相对第二干涉部1321固定不动；当滑块351a相对滑槽321a固定不动时，第一干涉部352相对第二干涉部1321固定不动。因此，这两种状态时，第一干涉部352均相对第二干涉部1321固定不动。本实施方式通过设置第一干涉部352与第二干涉部1321，使辅助件35直接固定连接于转动件13上，从而既可提高转轴套件3的连接性能，又可避免设置额外的限位结构，减小转轴套件3的尺寸，降低生产成本与组装成本。
第二种辅助件35与开孔132的连接方式请再次参考图15，本实施方式中，辅助件35与开孔132过盈配合。辅助件35与开孔132在上文已经进行了详细的描述，本申请在此不再赘述。其中，过盈配合是指辅助件35的径向尺寸(如图15中H2所示)不小于开孔132的径向尺寸(如图15中H3所示)，以使辅助件35不可相对于转动件13转动，故本实施方式可通过使辅助件35与开孔132过盈配合，使辅助件35固定连接与转动件13上，从而既可提高转轴套件3的连接性能，又可避免设置额外的限位结构，减小转轴套件3的尺寸，降低生产成本。
另外，在又一种实施方式中第一滑动部351与第二滑动部321的结构请参考图21，图21为本申请又一实施方式中第一滑动部与第二滑动部相配合的示意图。本实施方式中，第一滑动部351为滑槽321a的辅助件35，第二滑动部321为滑块351a，且转动件13相对传动件32滑动时，辅助件35相对转动件13转动。如图21所示，当转动件13相对传动件32滑动时，滑块351a沿滑槽321a相对传动件32滑动；当转动件13、及传动件32停止转动时，滑块351a相对滑槽321a固定不动。这两种状态时，至少部分滑块351a均始终设于滑槽321a内。当转动件13相对传动件32滑动时，至少部分辅助件35相对转动件13转动，以补偿第一转动中心与第二转动中心之间的间隙产生的位移偏差。需要说明的是，当转动件13相对传动件32静止时，辅助件35与转动件13可以相对静止，可以相对固定。另外，本实施方式中的滑槽321a的延伸方向与传动件32的延伸方向相互平行，可进一步减小传动件32的尺寸。因此，本实施方式可通过设置滑槽321a、滑块351a及辅助件35，使三者相配合，从而防止转动件13与传动件32相互卡死，既可以确保转轴套件3工作的稳定性，又可以降低转轴套件3的尺寸厚度。
可选地，包括滑槽321a的辅助件35设有第一干涉部，为滑块351a的第二滑动部321设有第二干涉部。当第一干涉部与第二干涉部相互配合时，滑槽321a与滑块351a相对静止。
接下来，介绍关于转动空间31a与传动件32配合的具体结构。请参考图22，图22为本申请又一实施方式中基座与传动件的立体结构示意图。本实施方式中，转动空间31a的侧壁上设有第一转动部311， 传动件32的外周侧壁上设有第二转动部322，第一转动部311与第二转动部322相互配合以使传动件32相对基座31转动。第一转动部311的转动轴线与第二转动部322的转动轴线重叠，以确保传动件32可相对于基座31稳定地转动。本实施方式对提供的第一转动部311与第二转动部322不进行限定，可以为任何形状的部件，仅需第一转动部311与第二转动部322对应设置即可。需要说明的是，在实际生产中，转动件13与第一转动部311是一体成型的结构件，即转动件13与第一转动部311通过一道工序制备而成，但为方便理解，人为地将转动件13与第一转动部311进行了不同的命名。同样地，在实际生产中，传动件32与第二转动部322是一体成型的结构件，但为方便理解，人为地将传动件32与第二转动部322进行了不同的命名。
可选地，当第一转动部311具有卡块时，第二转动部322对应具有卡槽；或者当第一转动部311具有卡槽时，第二转动部322对应具有卡块。当第一转动部311与第二转动部322相互配合时，至少部分卡块设于卡槽内。更进一步可选地，卡块可为半圆弧卡块，卡槽可为半圆弧卡槽。
如图22所示，当传动件32相对基座31转动时，第一转动部311相对第二转动部322转动；当传动件32相对基座31固定不动时，第一转动部311相对第二转动部322固定不动。这两种状态时，第一转动部311始终与第二转动部322相配合。因此，本实施方式通过设置第一转动部311与第二转动部322，使传动件32可相对基座31转动，从而带动传动件32相对转轴11转动。
可选地，请参考图23，图23为本申请又一实施方式中基座与转轴的立体结构示意图。转轴11靠近基座31的一侧设有第一连接部113，基座31靠近转轴11的一侧设有第二连接部312，第一连接部113与第二连接部312相互配合以使转轴11连接基座31。需要说明的是，转轴11可相对基座31转动。本实施方式可通过使第一连接部113与第二连接部312相配合，使转轴11连接至基座31上，从而可提高转轴套件3的连接性能。
进一步可选地，当第一连接部113具有卡块时，第二连接部312具有卡槽；或者当第一连接部113具有卡槽时，第二连接部312具有卡块；当第一连接部113与第二连接部312相互配合时，至少部分卡块设于卡槽内。
请参考图24与图25，图24为本申请又一实施方式中转轴套件的立体结构示意图。图25为本申请又一实施方式中同步组件的立体结构示意图。本实施方式中，扭矩组件1还包括齿轮33，齿轮33套设且连接于转轴11，齿轮33位于基座31与第一阻挡件12之间；两个齿轮33转动连接，使两个转动件13相向或背向同步转动。由于齿轮33套设且连接于转轴11上，当转轴11相对滑动件14转动时，齿轮33也相对滑动件14转动。并且，齿轮33位于基座31与第一阻挡件12之间，基座31与第一阻挡件12可限制齿轮33在转轴11上的轴向滑动。需要说明的是，齿轮33与转轴11可以为一体成型的结构件，也可以为分别独立成型，再进行装配的结构件。
如图24所示，当转轴11与转动件13相对滑动件14转动时，转轴11带动齿轮33也相对滑动件14转动。当转轴11与转动件13相对滑动件14固定不动时，转轴11带动齿轮33也相对滑动件14固定不动。齿轮33具有两种运动状态，一种运动状态为，当一个转动件13朝向远离转轴11的方向转动时，使一个齿轮33朝向靠近转动件13的方向转动，由于两个齿轮33转动连接，从而带动另一个齿轮33朝向靠近另一个转动件13的方向转动，进而使另一个转动件13也朝向远离转轴11的方向转动，以实现两个转动件13相背转动。另一种运动状态为，当一个转动件13朝向靠近转轴11的方向转动时，使一个齿轮33朝向靠近另一个齿轮33的方向转动，由于两个齿轮33转动连接，从而带动另一个齿轮33也朝向靠近齿轮33的方向转动，进而使另一个转动件13也朝向靠近转轴11的方向转动，以实现两个转动件13相向转动。因此，本实施方式可通过设置两个转动连接的齿轮33，使两个转动件13相向或背向同步转动，以提高两个转轴套件3之间的同步性能，提高转轴套件3转动的稳定性能。
请再次参考图24，本实施方式中，转轴套件3还包括同步组件34，同步组件34的一端转动连接一个齿轮33，另一端转动连接另一个齿轮33。
可选地，同步组件34转动连接于基座31与第一阻挡件12之间。可选地，两个齿轮33通过同步组 件34间接转动连接，同步组件34包括但不限于皮带、齿轮33组件等等。需要注意的是，为了确保可使两个转动件13相向或背向同步转动，如果同步组件34为齿轮组件，齿轮组件的齿轮数需为双数。进一步可选地，本实施方式中的同步组件34包括第一子齿轮与第二子齿轮，第一子齿轮与第二子齿轮转动连接，且第一子齿轮转动连接一个齿轮，第二子齿轮转动连接另一个齿轮。通过设置同步组件34间接转动连接两个齿轮33，使两个转动件13相向或背向同步转动，以提高两个转轴套件3之间的同步性能，提高转轴套件3转动的稳定性能。
目前，人们对电子设备的期待与要求越来越高。为了提高电子设备的便携性，通常通过转轴套件3，使电子设备具有合并状态。其中，合并状态是指使电子设备呈U型折叠的状态。由于U型折叠的特点，弯折后的转轴套件3存在缝隙，即电子设备合并后中间存在缝隙。但是，转轴套件3占用电子设备的内部空间较多，从而导致合并状态时的合并间隙较大。
请一并参考图26-图28，图26为本申请一实施方式中电子设备处于展开状态时的立体结构示意图。图27为本申请一实施方式中电子设备去除柔性屏的立体结构示意图。图28为本申请一实施方式中电子设备处于合并状态时的立体结构示意图。
电子设备4包括两个壳体41、柔性屏42、及如本申请提供的转轴套件3，两个壳体41的至少部分设于转轴套件3的相对两侧，且壳体41可拆卸连接于转轴套件3中的传动件32；柔性屏42装设于壳体41与转轴套件3中的传动件32上。
壳体41通常用于固定、支撑或者保护电子设备4的其他部件，甚至壳体41的设置还可以提高外观性能。壳体41的材料包括但不限于塑料、金属等。本实施方式提供的壳体41可以为任何形状的部件，本申请对此不进行限定，仅需壳体41至少部分设于转轴套件3的相对两侧，且壳体41与传动件32可拆卸连接即可。可选地，壳体41与传动件32的可拆卸连接包括但不限于螺纹连接、卡扣连接等等。进一步可选地，本实施方式中壳体41与传动件32通过螺钉以实现可拆卸连接。另外，由于壳体41与传动件32连接，且两个壳体41的至少部分设于转轴套件3的相对两侧，当两个传动件32相对基座31转动时，两个转动件13可带动两个壳体41同步转动。
柔性屏42通常用于显示画面、文字等信息，且由于柔性屏42自身具有柔性，在外力的作用下，柔性屏42可发生弯折形变，也可回复形变，即回复至受到外力前的状态。本实施方式提供的柔性屏42可以为任何形状的部件，本申请对此不进行限定，仅需柔性屏42装设于壳体41与转轴套件3中的传动件32上即可。由于柔性屏42装设于壳体41与传动件32上，当两个转动件13与两个壳体41转动时，转动件13与壳体41可带动柔性屏42发生形变；当两个转动件13与两个壳体41固定不动时，由于转轴套件3具有悬停与自紧的功能，柔性屏42也固定不动，故使电子设备4具有展开状态与合并状态。其中，如图26所示，展开状态是指柔性屏42水平展开180°，即柔性屏42未弯折；如图28所示，合并状态是指柔性屏42弯折，且柔性屏42的至少部分具有间隙。并且，转轴套件3在上文已经进行了详细的描述，本申请在此不再赘述。需要说明的是，当在电子设备4中使用一个或者多个转轴套件3时，均可以实现通过转轴套件3带动其他部件相对基座31转动，及悬停。图27仅以两个转轴套件3应用于电子设备4来进行示意说明，但这并不代表一定要使用两个转轴套件3应用于电子设备4中。
如图26所示，本实施方式中提供的电子设备4，通过使用本申请提供的转轴套件3，可通过第一弹性件16来提供压力进而提供摩擦力。故相较于相关技术，不仅可提高悬停、自紧效果，而且当需提供同样的摩擦力实现悬停时，本申请的转轴套件3可采用更小的尺寸，提高了转轴套件3结构的紧凑性，减少转轴套件3占用电子设备4的内部空间，从而为其他部件留下更多的内部空间，提高电子设备4的工作性能，还可减小电子设备4的重量，降低生产成本，提高电子设备4整机的竞争力。并且，由于本实施方式中的转轴套件3可采用更小的尺寸，转轴套件3中两个扭矩组件1间的间隙更小。也可以理解为，通过采用更小尺寸的扭矩组件1，可减小转轴套件3的弯折半径，即减小电子设备4的弯折半径，从而使弯折后柔性屏42之间的缝隙更小，即当电子设备4处于合并状态时，柔性屏42相对两侧之间的间隙更小，提高电子设备4的外观性能。
请参考图29，图29为本申请另一实施方式中电子设备去除柔性屏的立体结构示意图。本实施方式中，电子设备4还包括两个支撑件43，两个支撑件43的至少部分设于两个转轴套件3之间，支撑件43的相对两端拆卸连接于两个转轴套件3中的传动件32，且两个支撑件43形成避让空间43a。
本实施方式中的电子设备4是由多个部件相互配合，以提供用户信息、实现交互等的综合设备。其中，本实施方式中使两个转轴套件3间隔设置，可提高电子设备4整体的扭力平衡。本实施方式中的电子设备4还包括支撑件43，支撑件43通常用于支撑、连接其他部件等。支撑件43设于壳体41与柔性屏42之间。可选地，支撑件43的至少部分与壳体41可拆卸连接，以进一步提高电子设备4的连接性能。支撑件43的材料包括但不限于塑料、金属等。本实施方式提供的支撑件43可以为任何形状的部件，本申请对此不进行限定，仅需支撑件43的至少部分连接两个转轴套件3即可。可选地，电子设备4包括间隔设置的两个转轴套件3。
可选地，如图29所示，所示支撑件43具有避让孔43b。避让孔43b可用于使设于支撑件43相对两侧的其他部件相连接，从而提高电子设备4结构的紧凑性。
可选地，支撑件43与传动件32的可拆卸连接包括但不限于螺纹连接、卡扣连接等等。进一步可选地，本实施方式中支撑件43与传动件32通过螺钉以实现可拆卸连接。当然在其他实施方式中支撑件43与传动件32的可拆卸连接也可通过其他方式实现。例如：支撑件43与传动件32两者中的一者具有卡槽，或者支撑件43与传动件32两者中的一者具有卡块，至少部分卡块设于卡槽中。
如图29所示，首先，由于支撑件43的至少部分连接传动件32，故可使当一个转轴套件3的传动件32相对基座31转动时，另一个转轴套件3的传动件32也相对基座31同步转动，以带动两个壳体41相向或者相背转动，从而使柔性屏42发生弯折。两个转轴套件3及支撑件43相互配合，使得两个壳体41与转轴套件3对称设置，可提高电子设备4支撑柔性屏42的平整性，其中平整性使指柔性屏42表面的水平程度，以及可提高电子设备4的扭力平衡，降低电子设备4的晃动倾向。其次，两个支撑件43形成避让空间43a，并且由于支撑件43的相对两端拆卸连接于两个转轴套件3中的传动件32，故避让空间43a与转轴套件3相对于两个传动件32的中心轴相对应，当两个传动件32转动时，避让空间43a可避让转轴套件3，以确保两个支撑件43不影响转轴套件3的转动与悬停，从而提高电子设备4运行的稳定性。另外，本申请的转轴套件3可采用更小的尺寸，可进一步减小避让空间43a的尺寸，从而既可提高电子设备4结构的紧凑性，又可减小电子设备4的弯折半径，从而使弯折后柔性屏42之间的缝隙更小。
请再次参考图28、图30及图31，图30为本申请又一实施方式电子设备的爆炸图。图31为本申请又一实施方式中电子设备去除壳体及柔性屏的立体结构示意图。本实施方式中，电子设备4还包括装饰件44，装饰件44具有收容空间44a，至少部分基座31、及至少部分转轴套件3设于收容空间44a内。装饰件44通常用于保护部件、或者提高部件的外观性能等。装饰件44较基座31远离柔性屏42。装饰件44的材料包括但不限于塑料、金属等。本实施方式提供的装饰件44可以为任何形状的部件，本申请对此不进行限定，仅需装饰件44的具有收容空间44a，且收容空间44a可收容至少部分基座31、及至少部分转轴套件3即可。
如图28、图30与图31所示，当电子设备4处于合并状态时，装饰件44可使转轴套件3始终设于电子设备4内部，避免因露出转轴套件3而导致电子设备4的外观性能降低。并且，由于电子设备4的功能需通过由多个部件相互配合实现，本实施方式通过增设装饰件44，以收容至少部分基座31、及至少部分转轴套件3，从而使至少部分基座31、及至少部分转轴套件3与电子设备4中的其他部件相分离，避免部件之间相互影响，从而进一步提高电子设备4各个部件运行的稳定性。
可选地，相关技术中的装饰件44垂直于基座31的尺寸通常为3.5mm以上。由于本实施方式采用尺寸更小的转轴套件3，因此可进一步减小装饰件44的尺寸，从而提高电子设备4结构的紧凑性。可选地，转轴套件3与装饰件44可拆卸连接。可选地，转轴套件3与装饰件44的可拆卸连接包括但不限于螺纹连接、卡扣连接等等。
进一步可选地，请再次参考图29，电子设备4还包括多个保护件45，保护件45较装饰件44靠近转轴套件3，保护件45与转轴套件3的可拆卸连接处对应设置，用于保护可拆卸连接处，既可提高电子设备4各个部件运行的稳定性，又可提高转轴套件3的外观性能。
请再次参考图26与图30，电子设备4具有柔性屏42展平时的展开状态；当电子设备4为展开状态时，两个壳体41围设形成容置空间41a，装饰件44设于容置空间41a内。当电子设备4处于展开状态时，两个壳体41可形成容置空间41a，以收容装饰件44，故至少部分基座31、及至少部分转轴套件3也设于容置空间41a内。由于本申请采用的转轴套件3可采用更小的尺寸，可进一步减小壳体41中容置空间41a的尺寸，从而提高电子设备4结构的紧凑性。并且，在展开状态时，两个壳体41可形成容置空间41a可用于保护装饰件44，提高电子设备4的外观性能。
可选地，转轴套件3与转轴套件3的部件均可采用兼容性设计，也可以理解为，由于转轴套件3与转轴套件3均包括两个扭矩组件1对称设置，因此转轴套件3与转轴套件3的功能相同的部件之间兼容性高，可提高部件的共用程度，降低物料成本，提高生产效率，有利于实现生产模块化。
可选地，扭矩组件1、转轴套件3、转轴套件3中的各个部件均可采用模块化生产，即分别独立生产各个部件后进行装配，以提高生产效率高，且可提高零件管控的可靠性。
以上对本申请实施方式所提供的内容进行了详细介绍，本文对本申请的原理及实施方式进行了阐述与说明，以上说明只是用于帮助理解本申请的方法及其核心思想；同时，对于本领域的一般技术人员，依据本申请的思想，在具体实施方式及应用范围上均会有改变之处，综上所述，本说明书内容不应理解为对本申请的限制。
