由于第一限位槽30c沿滑动槽30b的一端朝远离安装孔30a的方向延伸，限位轴50容纳于第一限位槽30c内维持支架10和转动件20处于第一状态。第二限位槽30d沿滑动槽30b的一端朝远离安装孔30a的方向延伸，限位轴50容纳于第二限位槽30d内维持支架10和转动件20处于第二状态。也就是说，当限位轴50容纳于第一限位槽30c或第二限位槽30d内时，能够限制支架10和转动件20绕第一转轴40转动，使得支架10和转动件20相对于支撑件30维持第一状态或第二状态不变。
需要说明的是，本申请实施例中的第一状态是指支架10和转动件20相对于支撑件30处于展开状态。第二状态是指支架10和转动件20相对于支撑件30处于折叠状态。
本申请实施例提供的折叠机构100，通过控制操控件60使转动件20和支架10绕第一 转轴40转动，从而使得转动件20和支架10可以相对于支撑件30转动，控制支架10和转动件20相对于支撑件30处于折叠状态或展开状态，结构简单，操作便捷。此外，第一转轴40和限位轴50之间的轴距较大，可有效解决支架10和转动件20相对支撑件30展开时，支架10和转动件20松散晃动的问题，可靠性高。
具体的，安装孔30a位于滑动槽30b靠近支架10的一侧。第一通孔10a位于第二通孔10b远离支撑件30的一侧。第三通孔20a位于第四通孔20b远离支撑件30的一侧。操控件60的一端位于支架10或转动件20的外部，也就是说，若转动件20套设在支架10中，则操控件60的一端位于支架10外，可以是支架10上形成有第一避让口，操控件60的一端通过第一避让口与转动件20连接，操控件60的另一端通过第一避让口位于支架10外。若支架10套设在转动件20中，则操控件60的一端位于转动件20外，可以是转动件20上形成有第二避让口，操控件60的一端通过第二避让口与支架10连接，操控件60的另一端通过第二避让口位于转动件20外。
在一些实施例中，第一转轴40可以为对锁螺栓。

可对操控件60位于支架10外的一端施力，操控件60相对于支架10转动，力传递至转动件20上，由于第三通孔20a为腰形孔，支架10和第一转轴40能够共同沿第三通孔20a滑动。即，带动转动件20相对支架10滑动。又由于第四通孔20b为圆孔，第二通孔10b为与第三通孔20a长度方向相同的腰形孔，转动件20带动限位轴50同步滑动，第二通孔10b用于避让限位轴50。第一转轴40沿第三通孔20a滑动的同时，限位轴50沿第一限位槽30c滑动，(当支架10和转动件20处于第一状态时，第一限位槽30c的长度方向与第二通孔10b的长度方向相同)，直至限位轴50脱离第一限位槽30c运动至滑动槽30b中。限位轴50脱离第一限位槽30c进入滑动槽30b，支架10和转动件20能够绕第一转轴40转动。以便支架10和转动件20由第一状态向第二状态切换。同理，限位轴50容纳于第二限位槽30d中时(即支架10和转动件20处于第二状态时，此时第二限位槽30d的长度方向与第二通孔10b的长度方向相同)，可以对操控件60位于支架10外的一端施力，操控件60相对于支架10转动，力传递至转动件20上，由于第三通孔20a为腰形孔，第一转轴40沿第三通孔20a滑动，带动转动件20相对于支架10滑动，又由于第四通孔20b为圆孔，转动件20带动限位轴50同步滑动，从而使得第一转轴40沿第三通孔20a滑动的同时，限位轴50沿第二限位槽30d滑动，直至限位轴50脱离第二限位槽30d运动至滑动槽30b中。限位轴50脱离第二限位槽30d进入滑动槽30b，支架10和转动件20能够绕第一转轴40转 动。使得支架10和转动件20由第二状态切换至第一状态。

可对操控件60位于转动件20外的一端施力，操控件60相对于转动件20转动，力传递至支架10上，由于第一通孔10a为腰形孔，转动件20和第一转轴40能够共同沿第一通孔10a滑动。即，带动支架10相对于转动件20滑动。又由于第二通孔10b为圆孔，第四通孔20b为与第一通孔10a长度方向相同的腰形孔，支架10带动限位轴50同步滑动，第四通孔20b用于避让限位轴50。第一转轴40沿第一通孔10a滑动的同时，限位轴50沿第一限位槽30c滑动，(当支架10和转动件20处于第一状态时，第一限位槽30c的长度方向与第四通孔20b的长度方向相同)，直至限位轴50脱离第一限位槽30c运动至滑动槽30b中。限位轴50脱离第一限位槽30c进入滑动槽30b，支架10和转动件20能够绕第一转轴40转动。以便支架10和转动件20由第一状态向第二状态切换。同理，限位轴50容纳于第二限位槽30d中时(即支架10和转动件20处于第二状态时，此时第二限位槽30d的长度方向与第四通孔20b的长度方向相同)，可以对操控件60位于转动件20外的一端施力，操控件60相对于转动件20转动，力传递至支架10上，第一转轴40沿第一通孔10a滑动，带动支架10相对于转动件20滑动，支架10带动限位轴50同步滑动，从而使得第一转轴40沿第一通孔10a滑动的同时，限位轴50沿第二限位槽30d滑动，直至限位轴50脱离第二限位槽30d运动至滑动槽30b中。限位轴50脱离第二限位槽30d进入滑动槽30b，支架10和转动件20能够绕第一转轴40转动。使得支架10和转动件20由第二状态切换至第一状态。

当然，操控件170也可以与第二限位轴160连接，操控件170能够驱动转动件120和支架110相对滑动后，使转动件120和支架110绕枢接件140同步转动。操控件170还可以与转动件120连接，操控件170也能够驱动转动件120和支架110相对滑动后，使转动件120和支架110绕枢接件140同步转动。上述结构的运动原理和操控件170与第一限位轴150连接从而通过操控件170驱动转动件120和支架110相对滑动的运动原理相同，在此不再赘述。
本申请实施例提供的折叠机构1100，通过控制操控件170使转动件120和支架110绕枢接件140相对于安装座130转动，控制支架110和转动件120相对于安装座130处于折叠状态或展开状态，结构简单，操作便捷。
在一些实施例中，枢接件140可以为转轴或对锁螺栓。
具体的，安装孔130a位于滑动槽130b远离支架110的一侧。第一通孔110a位于第二通孔110b远离安装座130的一侧。第三通孔120a位于第四通孔120b远离安装座130的一侧。操控件170的一端位于支架110或转动件120的外部，也就是说，若转动件120套设在支架110中，则操控件170的一端位于支架110外，可以是支架110上形成有第一避让口，操控件170的一端通过第一避让口与第一限位轴150连接，操控件170的另一端通过第一避让口位于支架110外。若支架110套设在转动件120中，则操控件170的一端位于转动件120外，可以是转动件120上形成有第二避让口，操控件170的一端通过第二避让口与第一限位轴150连接，操控件170的另一端通过第二避让口位于转动件120外。
在一实施例中，请参见图9和图14，转动件120套设在支架110中。第一通孔110a为腰形孔，第二通孔110b为腰形孔。操控件170与支架110枢接，操控件170的一端伸入支架110内与第一限位轴150连接。
由于第一通孔110a为腰形孔，第二通孔110b为腰形孔。对操控件170施力时，操控件170相对于支架110转动，力传递至第一限位轴150上，带动第一限位轴150沿第一通孔110a滑动，第一限位轴150带动转动件120相对于支架110滑动，转动件120带动第二限位轴160沿第二通孔110b和第一限位槽130c滑动，直至第二限位轴160脱离第一限位槽130c进入滑动槽130b内，支架110和转动件120能够绕枢接件140相对于安装座130转动，以便支架110和转动件120在第一状态和第二状态之间切换。同理，当第二限位轴160位于第二限位槽130d内，对操控件170施力，操控件170相对于支架110转动，力传递至第一限位轴150上，带动第一限位轴150沿第一通孔110a滑动，第一限位轴150带动转动件120相对于支架110滑动，转动件120带动第二限位轴160沿第二通孔110b和第二限位槽130d滑动，直至第二限位轴160脱离第二限位槽130d进入滑动槽130b内，支架110和转动件120能够绕枢接件140相对于安装座130转动，以便支架110和转动件120在第一状态和第二状态之间切换。
在另一未示出的实施例中，支架110套设在转动件120中。第三通孔120a为腰形孔，第四通孔120b为腰形孔。操控件170与转动件120枢接，操控件170的一端伸入转动件120内与第一限位轴150连接。
由于第三通孔120a为腰形孔，第四通孔120b为腰形孔。对操控件170施力时，操控件170相对于转动件120转动，力传递至第一限位轴150上，带动第一限位轴150沿第三通孔120a滑动，第一限位轴150带动支架110相对于转动件120滑动，支架110带动第二限位轴160沿第四通孔120b和第一限位槽130c滑动，直至第二限位轴160脱离第一限位槽130c进入滑动槽130b内，支架110和转动件120能够绕枢接件140相对于安装座130转动，以便支架110和转动件120在第一状态和第二状态之间切换。同理，当第二限位轴 160位于第二限位槽130d内，对操控件170施力，操控件170相对于转动件120转动，力传递至第一限位轴150上，带动第一限位轴150沿第三通孔120a滑动，第一限位轴150带动支架110相对于转动件120滑动，支架110带动第二限位轴160沿第四通孔120b和第二限位槽130d滑动，直至第二限位轴160脱离第二限位槽130d进入滑动槽130b内，支架110和转动件120能够绕枢接件140相对于安装座130转动，以便支架110和转动件120在第一状态和第二状态之间切换。
可以理解的是，操控件170与支架110或转动件120中位于外部的一个枢接，也就是说，操控件170与第一限位轴150的受力方向可能相反。
在一些实施例中，操控件170可以与支架110或转动件120中位于外部的一个滑动连接。在一具体实施例中，转动件120套设在支架110中，操控件170与支架110滑动连接。操控件170受力相对于支架110滑动，带动第一限位轴150相对于支架110滑动，从而带动转动件120相对于支架110滑动。也就是说，第一限位轴150与操控件170的受力方向一致。在另一具体实施例中，支架110套设在转动件120中，操控件170与转动件120滑动连接。操控件170受力相对于转动件120滑动，带动第一限位轴150相对于转动件120滑动，从而带动支架110相对于转动件120滑动。
在一未示出的实施例中，操控件170包括连接部(图未示出)以及施力部(图未示出)。连接部与支架110和转动件120中位于外部的一个枢接，连接部的一端与第一限位轴150连接。施力部与连接部的另一端连接，施力部位于支架110和转动件120外。
在一具体实施例中，转动件120套设在支架110中。连接部与支架110枢接，连接部的一端与第一限位轴150连接。施力部与连接部的另一端连接，施力部位于支架110和转动件120外。
在另一具体实施例中，支架110套设在转动件120中。连接部与转动件枢接，连接部的一端与第一限位轴连接。施力部与连接部的另一端连接，施力部位于支架110和转动件120外。
在一实施例中，连接部的一端形成有安装槽，第一限位轴150位于安装槽内，连接部可以带动第一限位轴150运动。具体的，连接部可以为拨叉。
在一未示出的实施例中，施力部与连接部的另一端枢接，连接部包括用于阻挡施力部朝靠近安装座130运动的凸出端。施力部与连接部的另一端枢接，也就是说，施力部相对于连接部可以转动，如此设计，便于将施力部收纳起来，避免误触施力部，还便于美化外观。通过凸出端阻挡施力部朝靠近安装座130运动，具体的，可以是施力部相对于连接部向靠近安装座方向转动，当施力部与凸出端抵接，凸出端向施力部产生反作用力，如此，凸出端阻挡施力部继续朝靠近安装座方向运动。此种设计，结构简单，便于施加在施力部 上的力传递至连接部，如此，通过对施力部施力，使得支架110相对转动件120滑动，从而实现支架110和转动件120绕枢接件140转动。
在一未示出的实施例中，操控件170包括设置于施力部70外表面的防滑层(图未示出)。防滑层增加摩擦力，从而便于对施力部施力。具体的，防滑层包括但不限于橡胶层、硅胶层或磨砂层。
在另一未示出的实施例中，施力部的外表面设置为防滑表面。防滑表面可以是对施力部进行磨砂处理形成。也可以是在施力部的外表面形成凹槽。凹槽可以为多个，多个凹槽可以平行分布，也可以交错分布。多个交错分布的凹槽可以呈网格或菱形格。也可以是在施力部的外表面形成凸起。凸起可以为多个，多个凸起可以平行分布，也可以交错分布。多个交错分布的凸起可以呈网格状或菱形格状。
可以理解的是，防滑层可以位于施力部受力的端面，可以位于施力部的整个外表面。
在一实施例中，安装座130上形成有第三限位槽130e，第二限位轴160容纳于第一限位槽内30c时，第一限位轴150容纳于第三限位槽130e内。
当第二限位轴160位于第一限位槽130c内，第一支架110和转动件120相对于安装座130处于第一状态，此时，第一限位轴150容纳于第三限位槽130e内，第三限位槽130e限制第一限位轴150的运动，也就是说，第一限位轴150和第二限位轴160共同限制第一支架110和转动件120相对于安装座130处于第一状态。当操控件170带动第一限位轴150运动时，不仅需要第二限位轴160能够脱离第一限位槽130c，还需要第一限位轴150同时脱离第三限位槽130e，才能使得第二限位轴160进入滑动槽130b内，如此，才能使得支架110和转动件120相对于安装座130转动。此种设计，进一步提高折叠机构1100的结构稳定性，提高结构的可靠性。
在一实施例中，请参见图9和图14，折叠机构1100包括弹性件180。弹性件180的一端与第一限位轴150连接，弹性件180的另一端与支架110和转动件120位于外部的一个连接。对操控件170施力，由于操控件170的一端与第一限位轴150连接，力传导至第一限位轴150上，第一限位轴150带动支架110和转动件120相对滑动，从而带动第二限位轴160沿滑动槽130b、第一限位槽130c和第二限位槽130d滑动。由于弹性件180的一端与第一限位轴150连接，弹性件180在拉力的作用下发生弹性形变，直至第一限位轴150带动第二限位轴160脱离第一限位槽130c或第二限位槽130d，此时可以释放操控件170，弹性件180恢复形变，第一限位轴150在弹性件180的作用下靠近安装座130，也就是说，通过弹性件180使得第一限位轴150平缓复位。此种设计，由于弹性件180存在弹性形变，则需要对第一限位轴150施加较大且朝远离安装座130方向的力才能使得第一限位轴150带动第二限位轴160运动，且只有对第一限位轴150持续施加上述方向的力才能使得第一 限位轴150带动第二限位轴160脱离第一限位槽130c或第二限位槽130d，因此，弹性件180还可以避免第一限位轴150被误触之后，第二限位轴160脱离第一限位槽130c或第二限位槽130d。
在一具体实施例中，转动件120套设在支架110中，则弹性件180的一端与第一限位轴150连接，弹性件180的另一端与支架110连接。
在另一具体实施例中，支架110套设在转动件120中。则弹性件180的一端与第一限位轴150连接，弹性件180的另一端与转动件120连接。
具体的，弹性件180可以为弹簧。在一些实施例中，第一限位轴150形成有定位槽，弹性件180的一端位于定位槽内。在一具体实施例中，定位槽沿第一限位轴150周向延伸，第一定位槽可以为环形槽，弹性件180为弹簧，弹性件180的端部弯曲形成为弯曲端，弹性件180的弯曲端位于定位槽内，如此，实现弹性件180的一端与第一限位轴150连接。
在一实施例中，请参见图8和图9，安装座130为两个，两个安装座130分别位于支架110或转动件120位于外部的一个的两侧。如此，便于将支架110、转动件120安装在安装座130上。
在一具体实施例中，转动件120套设于支架110中，两个安装座130分别位于支架110的两侧。
在另一具体实施例中，支架110套设于转动件120中，两个安装座130分别位于转动件的两侧。
在一实施例中，请参见图8和图9，转动件120套设于支架110中。支架110包括一端开口的架体111和盖合在架体111开口处的端盖112。如此，可将弹性件180或转动件120设置于架体111内，不仅外观美观，还能保护弹性件180或转动件120。
具体的，架体111与端盖112可以是可拆卸式连接。例如，卡接或通过螺栓连接。
在一实施例中，请参见图8～图14，支架110上形成有定位孔110c，弹性件180的一端穿过定位孔110c，如此，实现弹性件180的一端与支架110连接。
可以理解的是，当支架110包括架体111和端盖112时，定位孔110c、第一通孔110a和第二通孔110b形成于架体111上。
在一实施例中，折叠机构1100包括设置在安装座130上的预紧件(图未示出)。第二限位轴150容纳于第一限位槽130c内时，预紧件的至少部分位于安装座130与支架110或转动件120位于外部的一个之间。
在一具体实施例中，转动件120套设于支架110中，第二限位轴150容纳于第一限位槽130c内时，预紧件的至少部分位于安装座130与支架110之间。
安装座130与支架110之间需要留存安装间隙，以便支架110相对安装座130转动。 通过在安装座130上设置预紧件，第二限位轴150容纳于第一限位槽130c内时，支架110和转动件120相对于安装座130处于第一状态，此时，预紧件的至少部分位于安装座130和支架110之间，预紧件可以填充安装座130与支架110之间的安装间隙，避免安装座130和支架110处于第一状态时，安装座130和支架110相对晃动。
在另一具体实施例中，支架110套设于转动件120中，第二限位轴150容纳于第一限位槽130c内时，预紧件的至少部分位于安装座130与转动件120之间。原理与上述原理相同，在此不再赘述。
可以理解的是，预紧件的至少部分位于安装座130和支架110之间，可以是预紧件的部分位于安装座130和支架110之间，也可以是预紧件的全部位于安装座130和支架110之间。预紧件的至少部分位于安装座130和转动件120之间，可以是预紧件的部分位于安装座130和转动件120之间，也可以是预紧件的全部位于安装座130和转动件120之间。
具体的，预紧件包括但不限于橡胶、硅胶或软塑料。
