具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合本申请具体实施例及相应的附图对本申请技术方案进行清楚、完整地描述。显然，所描述的实施例仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
以下结合附图，详细说明本申请各个实施例公开的技术方案。
如图1-图21所示，本申请实施例公开一种折叠机构，其包括第一折叠页410a、第二折叠页410b、第一移动盖110a、第二移动盖110b、第一联动组件300a、第二联动组件300b和转轴200。折叠机构可以应用在电子设备中，使电子设备具备折叠功能，电子设备通常可以包括显示屏900。
其中，第一折叠页410a和第二折叠页410b为折叠机构中的主体结构，第一折叠页410a和第二折叠页410b均可以提供支撑作用，具体为支撑电子设备中的显示屏900。
通常来说，在折叠式的电子设备中，随着电子设备的折叠和展开动作的进行，电子设备的相背两侧会出现不等长的情况，因此，需要在设计电子设备的过程中，解决内外侧不等长的问题，并且，针对电子设备的折叠方式而言，在电子设备采用屏幕内折或屏幕外折的不同折叠方式的情况下，对于折叠机构的解决方案亦有所不同。如上所述，本申请实施例公开的折叠机构中，第一折叠页410a和第二折叠页410b可以支撑屏幕，为了尽量降低柔性屏的被折叠幅度，本申请提供的折叠机构可以采用屏幕外折的方式进行折叠，也即，折叠机构处于折叠状态时，柔性屏位于折叠机构之外。
第一移动盖110a和第二移动盖110b即为折叠机构中解决内外侧不等长的具体机构之一，在折叠机构的折叠状态和展开状态相互切换的过程中，通过使第一移动盖110a与第一折叠页410a的相对位置，以及第二移动盖110b和第二折叠页410b的相对位置发生改变，使折叠机构能够正常地在折叠状态和展开状态之间进行切换。
可选地，在折叠机构中，可以根据实际情况确定第一折叠页410a和第二折叠页410b的具体结构，二者的具体结构和尺寸等参数可以不同，为了使折叠机构和包括该折叠机构的电子设备更加对阵，且可以使电子设备处于折叠状态时的尺寸相对更小，可以使第一折叠页410a和第二折叠页410b的形状和尺寸对应相同，二者对称设置。基于此，第一移动盖110a和第二移动盖110b的形状和尺寸也对应相同，且第一移动盖110a和第二移动盖110b对称 设置，折叠机构中转轴200的轴线所在的平面为前述二者的对称平面。另外，第一移动盖110a通过第一联动组件300a与第一折叠页410a连接，第二移动盖110b通过第二联动组件300b与第二折叠页410b连接，在第一折叠页410a和第二折叠页410b的结构相同，且第一移动盖110a和第二移动盖110b的结构相同的情况下，也可以使第一联动组件300a和第二联动组件300b的结构相同。
第二折叠页410b位于第一折叠页410a的一侧，第二折叠页410b和第一折叠页410a通过转轴组件800相连，转轴组件800具体可以为铰链结构件或是轴类结构件，以通过转轴组件800使第一折叠页410a能够与第二折叠页410b相对转动，详细地，第一折叠页410a和第二折叠页410b能够分别绕转轴组件800转动，使第一折叠页410a和第二折叠页410b在展开状态和折叠状态之间可切换，在展开状态，第一折叠页410a和第二折叠页410b共面，具体体现为第一折叠页410a中用于支撑显示屏900的支撑面与第二折叠页410b中用于支撑显示屏900的支撑面共面，这使得显示屏900的显示面位于同一平面内。在折叠状态，第一折叠页410a和第二折叠页410b叠置，具体体现为第一折叠页410a和第二折叠页410b层叠设置，且第一折叠页410a的支撑面与第二折叠页410b的支撑面相背设置，且两个支撑面均外露设置。
第一联动组件300a和第二联动组件300b通过转轴200转动连接，转轴200可以为长直条状的圆柱杆，第一联动组件300a和第二联动组件300b均可以与转轴200铰接，从而使第一联动组件300a和第二联动组件300b均能够相对转轴200转动，且可以使第一联动组件300a和第二联动组件300b连接为一体，进而使第一移动盖110a和第二移动盖110b能够与第一折叠页410a和第二折叠页410b组装连接在一起。其中，转轴200的转动轴线和转轴组件800的转动轴线位于同一平面内，且该平面与处于展开状态下的第一折叠页410a的支撑面垂直。
第一联动组件300a和第二联动组件300b的作用相同，通过第一联动组件300a，可以在第一折叠页410a与第二折叠页410b相对转动的过程中，使 第一移动盖110a与第一折叠页410a之间亦产生相对运动，对应地，随着第一折叠页410a与第二折叠页410b相对转动，第二联动组件300b可以驱动第二移动盖110b与第二折叠页410b相对运动，进而在折叠机构处于展开状态的情况下，使第一移动盖110a和第二移动盖110b相互对接，以遮挡位于第一移动盖110a和第一折叠页410a之间，以及第二移动盖110b和第二折叠页410b之间的其他结构，且防止外界的灰尘等杂物进入折叠机构中；对应地，在折叠机构处于折叠状态的情况下，由于第一移动盖110a和第二移动盖110b位于内侧，为了保证折叠机构能够正常地自展开状态切换至折叠状态，需要使第一移动盖110a和第二移动盖110b相互分离，以需要减小内侧的整体长。
基于上述情况，在折叠机构自展开状态向折叠状态切换的过程中，第一联动组件300a带动第一移动盖110a朝向第一折叠页410a移动，且第二联动组件300b带动第二移动盖110b朝向第二折叠页410b移动。可选地，第一联动组件300a和第二联动组件300b为直线电机，在折叠机构切换状态的过程中，第一联动组件300a和第二联动组件300b可以分别驱动第一移动盖110a和第二移动盖110b移动。
详细地说，第一移动盖110a向第一折叠页410a中与转轴组件800相对的一侧移动。更直观地，以转轴组件800的转动轴向为折叠机构的宽度方向为例，则垂直于第一折叠页410a的方向为折叠机构的厚度方向，同时垂直于宽度方向和厚度方向的方向为折叠机构的长度方向，前述长度方向还与转轴200轴向垂直，在上述技术方案中，处于展开转台的折叠机构中，第一移动盖110a和第二移动盖110b沿前述长度方向分布，在折叠机构转换至折叠状态的过程中，第一移动盖110a沿长度方向向背离第二移动盖110b的方向移动，当然，在上述过程中，由于第一移动盖110a和第二移动盖110b的相对位置始终在发生变化，因此，仅以折叠机构最开始向折叠状态切换的一瞬间的情况举例，更直观地说明第一移动盖110a的具体移动情况，并不对技术方案产生严格的限定意义。
可选地，第一折叠页410a包括一侧壁，对应地，第二折叠页410b也可 以包括类似的一侧壁，在折叠机构处于展开状态下，前述两个侧壁沿折叠机构的长度方向相对，且沿长度方向，转轴200、第一移动盖110a、第二移动盖110b和转轴组件800均位于前述两个侧壁之间。更具体地，第一折叠页410a的上述侧壁可以为下文提及的第三侧壁415。
基于上述内容，在折叠机构自展开状态向折叠状态切换的过程中，第一联动组件300a带动第一移动盖110a朝向第一折叠页410a移动，这一技术方案也可以被理解为第一联动组件300a带动第一移动盖110a向靠近第一折叠页410a的前述侧壁的方向运动。对应地，第二联动组件300b带动第二移动盖110b朝向第二折叠页410b移动，则为第二联动组件300b带动第二移动盖110b向靠近第二折叠页410b的前述侧壁的方向运动。
本申请公开的折叠机构可以应用于电子设备中，使电子设备具有折叠和展开两种状态，电子设备处于展开状态的情况下，其显示面积相对较大，电子设备处于折叠状态的情况下，可以在一定程度上提升便携性，从而使电子设备能够兼顾较大的显示面积和较好的便携性。
折叠机构包括第一折叠页410a、第二折叠页410b、第一移动盖110a、第二移动盖110b、第一联动组件300a、第二联动组件300b和转轴200，第一折叠页410a和第二折叠页410b通过转轴组件800转动连接，第一移动盖110a通过第一联动组件300a与第一折叠页410a连接，第二移动盖110b通过第二联动组件300b与第二折叠页410b连接，第一联动组件300a和第二联动组件300b之间通过转轴200连接，形成折叠机构。折叠机构自展开状态向折叠状态切换的过程中，第一联动组件300a能够带动第一移动盖110a朝向第一折叠页410a移动，第二联动组件300b能够带动第二移动盖110b朝向第二折叠页410b移动，使第一移动盖110a和第二移动盖110b相互分离，保证折叠机构的折叠过程能够正常进行。
另外，在上述实施例提供的折叠机构自折叠状态向展开状态切换的过程中，第一联动组件300a带动第一移动盖110a远离第一折叠页410a移动，且第二联动组件300b带动第二移动盖110b远离第二折叠页410b移动，从而使 第一移动盖110a和第二移动盖110b逐渐靠近，且在折叠机构处于展开状态时，可以使第一移动盖110a和第二移动盖110b能够相互对接。
更直观地，在第一折叠页410a和第二折叠页410b均包括上述侧壁的情况下，可以认为第一联动组件300a带动第一移动盖110a向远离第一折叠页410a的前述侧壁的方向运动，第二联动组件300b带动第二移动盖110b向远离第二折叠页410b的前述侧壁的方向运动，以使第一移动盖110a和第二移动盖110b能够相互靠近，且最终对接至一起。
可选地，第一一联动组件包括连接块310、第一齿条320、第二齿条330、第一齿轮340和第二齿轮350。
连接块310活动设置在于第一折叠页410a和第一移动盖110a之间，也即，第一折叠页410a和第一移动盖110a相对设置，连接块310夹设在前述二者之间，并且，连接块310能够相对第一折叠页410a和第一移动盖110a运动。同时，连接块310与转轴200转动连接。详细地，连接块310可以套设在转轴200之外，这可以保证连接块310和转轴200之间的连接关系和转动配合关系均相对较好。
第一齿条320连接在连接块310上，第二齿条330连接在第一移动盖110a上，第一齿轮340与第一齿条320啮合，第二齿轮350与第二齿条330啮合，第二齿轮350与第一齿轮340均安装于第一折叠页410a，且同轴转动，第二齿条330和第一齿条320同向延伸，保证在第一齿轮340和第一齿条320啮合的过程中，第二齿轮350亦可以始终保持与第二齿条330啮合的状态。具体地，通过焊接或粘接等方式，可以将第一齿条320固定在连接块310上，且将第二齿条330固定在第一移动盖110a上；并且，可以在第一折叠页410a上固定一轮轴360，使第一齿轮340和第二齿轮350均套设安装在该轮轴360上，且借助限位结构，或者直接将第一齿轮340和第二尺寸固定在一起，即可使第一齿轮340和第二尺寸能够同轴转动。
第一齿条320、第二齿条330、第一齿轮340和第二齿轮350为第一联动组件300a中提供传动作用的部件，通过前述几者，可以随第一折叠页410a 和第二折叠页410b相对运动的过程，借助第一折叠页410a和第二折叠页410b相对转动产生的作用力，使第一移动盖110a相对第一折叠页410a移动。当然，为了保证上述动作能够正常进行，需要对第一齿条320和第二齿条330的延伸方向进行限制，例如，第一齿条320和第二齿条330不能沿转轴200的轴向延伸，第一齿条320和第二齿条330的延伸方向均必须具有垂直于转轴200的方向上的分量，在本申请的一个具体实施例中，第一齿条320和第二齿条330的延伸方向均垂直于转轴200。
更详细地，如图2、图13和图15所示，连接块310转动安装在转轴200上，且可以相对第一折叠页410a运动。在折叠机构自展开状态切换至折叠状态的过程中，连接块310随第一折叠页410a转动的同时，沿垂直于转轴200的方向，连接块310与转轴200连接的一端与第一齿轮340的轮轴360之间的间距逐渐变小，从而使设置在连接块310上的第一齿条320驱动第一齿轮340转动，第一齿轮340转动会使第二齿轮350一并转动，第二齿轮350与第二齿条330啮合，由于第一齿轮340和第二齿轮350同轴转动，二者的转动方向相同，使得第二齿条330和第一齿条320同向移动，如上所述，在第一折叠页410a的转动过程中，第一齿条320靠近转轴200的一端与第一齿轮340的轮轴360之间的间距逐渐减小，则第二齿条330可以向远离转轴200的方向运动，或者说，第二齿条330可以向靠近第一折叠页410a的上述侧壁的方向运动，第二齿条330与第一移动盖110a一体设置，从而可以使第一移动盖110a朝向第一折叠页410a移动，也即，第一移动盖110a向靠近第一折叠页410a的上述侧壁的方向移动。在第二移动盖110b也对应移动的情况下，可以使第一移动盖110a和第二移动盖110b相互远离。
相应地，在折叠机构自折叠状态切换至展开状态的过程中，连接块310靠近转轴200的一端与第一齿轮340的轮轴360之间的间距逐渐增大，由于第一齿轮340和第二齿轮350同轴且同向转动，在第一齿条320、第一齿轮340、第二齿条330和第二齿轮350的传动作用下，第二齿条330靠近转轴200的一端与第一齿轮340的轮轴360之间的间距也逐渐增大，从而使第一 移动盖110a向远离第一折叠页410a的上述侧壁的方向移动。在在第二移动盖110b也对应移动的情况下，可以使第一移动盖110a和第二移动盖110b相互靠近，且使第一移动盖110a和第二移动盖110b最终能够对接在一起。
进一步地，如图2和图13所示，折叠机构还可以包括第一限位块420，第一限位块420固定于第一折叠页410a朝向第一移动盖110a的表面。具体地，第一限位块420可以通过粘接或焊接等方式固定在第一折叠页410a上。连接块310设有限位孔313，沿第一齿条320的延伸方向，第一限位块420滑动设置于限位孔313。具体地，限位孔313的尺寸和形状可以根据第一限位块420的尺寸和形状对应设计，且在第一齿条320的延伸方向上，使限位孔313的尺寸大于第一限位块420的尺寸，保证第一限位块420能够在限位孔313的相背两端之间滑动，改变第一齿条320和第一齿轮340之间的相对位置，进而使折叠机构在折叠状态和展开状态之间相互切换。
在采用上述技术方案的情况下，可以借助与第一折叠页410a相对固定的第一限位块420对连接块310相对第一折叠页410a的最大位移量进行限制，进而无需使用户采用人工的方式控制折叠和展开的角度，降低折叠机构的用户操作难度，通过使第一限位块420与限位孔313相互限位，可以保证第一折叠页410a和第二折叠页410b仅能在预设角度范围内相对转动，防止因第一折叠页410a和第二折叠页410b过度转动而破坏第一移动盖110a和第二移动盖110b，以及显示屏900。可选地，前述预设角度范围可以为0°～180°，保证折叠机构能够正常地在折叠状态和展开状态相互切换。
进一步地，如图13和图15所示，折叠机构还可以包括第二限位块430，第二限位块430在第一齿条320的延伸方向的尺寸可以与第一连接块310的尺寸相等。限位孔313内设有卡持部314，卡持部314具体可以为卡持凸沿，卡持部314可以形成在限位孔313的内壁上。第二限位块430自限位孔313朝向第一移动盖110a的一端伸入至限位孔313内，由于限位孔313的内壁设有卡持部314，从而在第二限位块430沿上述方向向限位孔313内伸入至一段距离之后，即会受卡持部314的限位作用影响，导致第二限位块430无法 继续向限位孔313内伸入。
第二限位块430可以通过螺钉或磁性等方式与第一限位块420形成可拆卸地固定连接关系，由于第一限位块420固定在第一折叠页410a上，通过与第一限位块420固定连接，可以使第二限位块430能够向卡持部314(即连接块310)施加限位作用，进而，沿垂直于第一齿条320的延伸方向的方向，连接块310与固定连接的第一限位块420和第二限位块430相对固定，在这种情况下，可以防止连接部以转轴200为轴，向背离第一折叠页410a朝向第一移动盖110a的表面移动，进而使第一齿条320稳定地与第一齿轮340保持啮合关系，以及使第二齿条330稳定地与第二齿轮350保持啮合关系。
可选地，如图13和图15所示，连接块310包括连接本体311和限位凸台312，连接本体311和限位凸台312固定连接，具体地，二者可以通过一体成型的方式形成，一方面可以降低加工难度，另一方面还可以提升二者之间的连接可靠性。
连接本体311与转轴200转动连接，具体可以在连接本体311上设置穿孔，使连接本体311可以套设在转轴200上，且与转轴200转动连接。第一齿条320连接于连接本体311，限位凸台312和第二齿条330均夹设于第一移动盖110a与连接本体311之间，第二齿条330夹设于限位凸台312和第二齿轮350之间。也就是说，连接本体311的一侧表面与第一折叠页410a固定连接，限位凸台312固定连接在连接本体311的另一侧，且限位凸台312背离连接本体311的一侧为第一移动盖110a。限位凸台312和连接本体311均可以为第二齿条330提供限位作用，从而使第一齿条320和第一齿轮340之间的配合稳定性，以及第二齿条330和第二齿轮350之间的稳定性均相对较高。
具体地，可以使第二齿条330和限位凸台312沿转轴200的轴向的尺寸之和等于连接本体311在前述方向上的尺寸，这可以提升折叠机构中结构的紧凑性，提升空间利用率，并且，可以使连接本体311能够在垂直于第一折叠页410a的方向上为第二齿条330提供可靠的限位效果。
可选地，如图13和图15所示，连接块310的相背两侧均设有第一齿条320，对应地，第二齿条330、第一齿轮340和第二齿轮350的数量也可以为多个，且与第一齿条320一一对应配合，从而提升第一折叠页410a和第一移动盖110a之间的连接可靠性，且可以提升第一移动盖110a被驱动时的稳定性。具体地，多个第一齿条320可以沿转轴200的轴向间隔设置，从而使第一移动盖110a上的各位置处均能在第一联动组件300a的作用下相对第一折叠页410a移动，防止第一移动盖110a在移动过程中因受力不均偏斜而卡滞。
可选地，如图10-图12所示，折叠机构还包括滑动组件500，滑动组件500包括滑动部510、第一转动部521和第二转动部522，滑动部510与转轴200滑动且转动连接，第一转动部521的一端与滑动部510转动连接，另一端与第一折叠页410a转动连接，第二转动部522的一端与滑动部510转动连接，另一端与第二折叠页410b转动连接。具体地，滑动部510可以为轴套，其可以套设安装在转轴200上，第一转动部521和第二转动部522均可以为杆状结构件，且二者的结构可以相同，二者均可以通过铰接件连接在滑动部510上，对应地，第一转动部521与第一折叠页410a之间，以及第二转动部522与第二折叠页410b之间也均可以通过铰接件转动连接。
在采用上述技术方案的情况下，当第一折叠页410a相对转轴200转动时，第一转动部521中与第一折叠页410a连接的一端与转轴200之间的间距会发生变化，进而可以驱动滑动部510在转轴200上沿转轴200的轴向移动，随着滑动部510相对转轴200移动，与滑动部510连接的第二转动部522与滑动部510之间的相对位置会发生变化，进而改变第二转动部522与第二折叠页410b连接的一端与转轴200之间的间距，从而使第二折叠页410b与第一折叠页410a产生相同的动作，即相对被折叠或相对被展开。因此，通过设置滑动组件500，可以使第一折叠页410a和第二折叠页410b之间的动作同步性更高，保证第一折叠页410a和第二折叠页410b之间同步展开或同步折叠。
可选地，如图10和图11所示，滑动组件500还包括弹性复位件530，弹性复位件530套设于转轴200，弹性复位件530具体可以为压缩弹簧，弹 性复位件530的一端与滑动部510连接，弹性复位件530的另一端固定于转轴200。在本实施例中，当折叠机构自展开状态切换至折叠状态时，第一转动部521的相对两端之间可以自最大间距值逐渐减小，直至第一转动部521的相对两端之间的间距达到最小值，在上述过程中，第一转动部521可以驱动滑动部510始终沿同一方向移动，且滑动部510的移动过程中会压缩弹性复位件530，使弹性复位件530储存弹性复位力。之后，在需要展开折叠机构时，弹性复位件530可以向滑动部510释放弹性复位力，一方面可以降低折叠机构的展开难度，另一方面可以保证滑动部510能够可靠地恢复至初始位置，而不会因卡滞等情况导致折叠机构无法正常展开。
具体地，弹性复位件530通过粘接等方式能够定位在滑动部510和转轴200的某一位置处，在本申请的另一实施例中，可选地，折叠机构还包括第一限位座和第二限位座，第一限位座和第二限位座均与转轴200固定连接，滑动部510活动设置于第一限位座和第二限位座之间，弹性复位件530背离滑动部510的一端抵接于第一限位座。
具体地，第一限位座和第二限位座具体可以为块状结构件，二者均可以通过焊接或粘接等方式固定在转轴200的预设位置处，且通过使第一限位座和第二限位座在转轴200的轴向上的间距大于滑动部510在对应方向上的尺寸，即可保证滑动部510能够在第一限位座和第二限位座之间滑动。并且，借助第一限位和第二限位座对滑动件进行限位，可以防止滑动部510在惯性等作用下出现过量移动的情况，导致折叠机构无法正常工作。同时，相比于直接连接在转轴200上，弹性复位件530与第一限位座之间的抵接定位关系更为稳定。更具体地，第一限位座可以为下文提及的支撑部730，第二限位座可以为转轴200的末端或第一联动组件300a等。
如上所述，滑动部510可以为轴套，在本申请的另一实施例中，可选地，滑动部510包括滑动本体511、第一销轴512和第二销轴513，滑动本体511设有通孔、第一连接孔和第二连接孔，滑动部510通过通孔套设于转轴200，第一销轴512转动设置于第一连接孔内，第一转动部521和第一销轴512转 动连接，第二销轴513转动设置于第二连接孔内，第二转动部522和第二销轴513转动连接。
在本实施例中，第一转动部521和第二转动部522均通过轴孔配合结构实现与滑动本体511转动连接的目的，使转动关系的顺畅性相对较高，且轴类结构均为销轴，可以保证前述转动连接关系的可靠性较高。另外，第一转动部521和第二转动部522亦可以通过轴孔连接结构分别转动连接在第一折叠页410a和第二折叠页410b上，且在前述连接关系中，轴类结构可以选择可拆卸连接的螺栓等部件，从而便于第一折叠页410a和第二折叠页410b与滑动组件500之间拆装工作的进行。
可选地，如图8-图11所示，本申请实施例公开的折叠机构还可以包括转轴座600，转轴座600具有两个转轴孔610，转轴200的数量为两个，两个转轴200平行且间隔设置，且两个转轴200分别插接于转轴座600的两个转轴孔610内，两个转轴200中的一者与第一联动组件300a转动连接，另一者与第二联动组件300b转动连接。在采用上述技术方案的情况下，第一移动盖110a和第二移动盖110b与转轴200之间的配合难度相对较小，且在各转轴200的尺寸相对较小的情况下，可以使第一移动盖110a和第二移动盖110b之间的间隔能够被设计得更大，进一步防止二者对折叠机构的折叠和展开过程产生妨碍。
具体地，两个转轴200的结构可以相同，以降低备件难度，且提升折叠机构的折叠精度。两个转轴200通过插接于转轴座600的两个转轴孔610内，可以组成一个整体，该整体的转动轴线位于两个转轴200之间。可选地，转轴座600的数量为多个，多个转轴座600分别设置在两个转轴200的不同位置处，可以提升两个转轴200之间的连接可靠性。
可选地，本申请实施例提供的折叠机构还包括安装部，安装部包括主梁710、第一限位部720和第二限位部740，第一限位部720固定于主梁710，第二限位部740与主梁710可拆卸地固定连接，转轴200夹设于第一限位部720和第二限位部740之间。其中，主梁710通过第一限位部720和第二限 位部740与转轴200配合，可以提升折叠机构中提供转动作用的结构的整体强度，且可以为转轴200提供一定的支撑和辅助作用，提升转动连接的精度。
具体地，主梁710、第一限位部720和第二限位部740均可以采用金属材料制成，第一限位部720可以与主梁710采用一体成型的方式形成，第二限位部740可以通过卡接或连接件连接等方式可拆卸地固定在主梁710上，且可以使第二限位部740与第一限位部720相对设置，即可保证转轴200能够被夹持在第一限位部720和第二限位部740之间。
为了进一步提升转轴200与安装部之间的配合可靠性，可选地，安装部还包括支撑部730，支撑部730固定于主梁710，具体可以使支撑部730与主梁710采用一体成型的方式形成。第一限位部720朝向支撑部730的一侧设有盲孔721，支撑部730设有贯穿孔731，转轴200穿过贯穿孔731且插接于盲孔721中，也就是说，支撑部730设置在第一限位部720的一侧，在安装转轴200的过程中，转轴200能够穿过贯穿孔731，且转轴200的一端能够插接且支撑在盲孔721中，由于转轴200亦插接在支撑部730的贯穿孔731内，进而支撑部730亦可以为转轴200提供较强的支撑作用，进而提升转轴200与主梁710之间的配合稳定性。为了防止转轴200意外与主梁710分离，如上所述，转轴200夹设在第一限位件和第二限位件之间，具体地，第二限位部740设置于支撑部730背离第一限位部720的一侧，第二限位件可以通过螺钉等连接件固定在主梁710上，在第二限位件的限位作用下，可以防止转轴200自支撑部730的贯穿孔731内脱出。
可选地，本申请实施例提供的折叠机构还包括桥接部750，安装部的数量为多个，相邻的两个安装部通过桥接部750连接，这可以减小每一转轴200的长度，且通过多个桥接部750对相邻的两个转轴200进行桥接，从而降低转轴200的发生变形的概率，提升折叠机构的可靠性。
如上所述，两个转轴200中的一者可以与第一联动组件300a连接，另一者可以与第二联动组件300b连接，可选地，第一联动组件300a和第二联动组件300b沿转轴200的轴向分布。在本申请的另一实施例中，如图10所示， 第一联动组件300a和第二联动组件300b沿垂直于转轴200的轴向的方向间隔设置，也即，第一联动组件300a和第二联动组件300b相对设置，在这种情况下，第一联动组件300a和第二联动组件300b之间的驱动方向相反，且动作情况一致，第一联动组件300a和第一移动盖110a的作用点与第二联动组件300b和第二移动盖110b的作用点对称设置，使得第一移动盖110a和第二移动盖110b在相对运动的过程中所受的力更均衡，基本不存在比较偏斜的作用力，从而可以提升第一移动盖110a和第二移动盖110b相对运动的稳定性。
可选地，第一联动组件300a和第二联动组件300b的数量均可以为多个，多个第一联动组件300a和多个第二联动组件300b一一对应配合，且可以使多个第一联动组件300a沿转轴200的轴向间隔排布。
进一步地，第一联动组件300a和第二联动组件300b均设有让位槽，让位槽内设置有转轴座600，转轴座600、第一联动组件300a和第二联动组件300b在转轴200的轴向限位配合，这可以对第一联动组件300a和第二联动组件300b的位置产生较强的限制作用，使第一联动组件300a和第二联动组件300b形成一个整体，在这种情况下，第一联动组件300a和第二联动组件300b一并沿转轴200的轴向运动的概率极低，从而可以保证折叠机构的可靠性相对较高。
另外，在转轴200的数量为两个的情况下，滑动部510上亦可以设置有两个穿孔，以分别与两个转轴200对应插接。可选地，如图10所示，滑动部510可以包括对称的两部分，两部分分别与两个转轴200转动配合，且两部分中的一者与第一转动部521连接，另一者与第二转动部522连接。为了保证前述结构的滑动部510可以使第一转动部521和第二转动部522同步动作，可以在滑动部510的前述两部分上，对应形成类似于第一联动组件300a和第二联动组件300b的让位槽式样的结构，且通过在让位槽内设置转轴座600，亦可以保证滑动部510的前述两部分能够在转轴200的轴向上相互限位。
可选地，如图7所示，第一折叠页410a包括承载部412和连接于承载部 412一侧的侧部，从而使第一折叠页410a为立体式结构，承载部412能够为显示屏900提供承载作用，承载部412具体可以为矩形板状结构件，以提供较为可靠的承载作用；可选地，承载部412的边角处可以设置有倒角，以使包括前述折叠机构的电子设备的边角更圆滑，提升整机的外观性能和手感。侧部即为第一折叠页410a的侧壁，其可以环绕设置在承载部412的边缘，从而为第一折叠页410a和第一移动盖110a之间的结构提供遮挡和防护作用，且保证折叠机构结构的完整性。
侧部包括第一侧壁413、第二侧壁414和第三侧壁415，第一侧壁413和第二侧壁414沿转轴200的轴向相对设置，结合上文对宽度方向的描述，可以认为第一侧壁413和第二侧壁414为折叠机构在宽度方向上的两个相对的侧壁；第三侧壁415连接于第一侧壁413和第二侧壁414之间，结合上文对长度方向的描述，第三侧壁415为电子设备在长度方向上的侧壁，另外，在第二折叠页410b亦采用上述结构的情况下，第二折叠页410b上的第三侧壁415可以与第一折叠页410a上的第三侧壁415共同构成电子设备长度方向上相对的两个侧壁。需要说明的是，上文中，为了辅助说明第一移动盖110a与第一折叠页410a相对移动方向，引出第一折叠页410a上包括一侧壁，前述侧壁即为第三侧壁415。
如上所述，第一移动盖110a通过第一联动组件300a与第一折叠页410a连接，为了提升第一移动盖110a和第一折叠页410a之间的连接可靠性，在本申请的另一实施例中，可选地，如图7、图16和图17所示，折叠机构还包括滑块120，滑块120可拆卸地固定于第一移动盖110a朝向第一折叠页410a的表面，保证第一移动盖110a和第一折叠页410a之间能够正常组件，具体地，滑块120可以通过螺钉等连接件可拆卸地固定在第一移动盖110a上，更具体地，如图17所述，第一移动盖110a上可以设置有穿孔，连接件可以穿过前述穿孔且伸入至滑块120中，实现可拆卸连接滑块120和第一移动盖110a的目的。
第一侧壁413和第二侧壁414中的至少一者设有滑槽411，滑槽411沿 垂直于转轴200轴向的方向延伸，更直观地说，第一折叠页410a上设置有沿上述长度方向延伸的滑槽411，滑块120和滑槽411滑动配合，从而随第一折叠页410a和第二折叠页410b的相对转动，可以使第一移动盖110a和第一折叠页410a在前述长度方向上的相对移动过程更稳定，且通过滑槽411可以为第一移动盖110a提供导向和限位作用，提升第一移动盖110a的移动精度，且降低第一移动盖110a的移动难度。
更具体地，在组装第一移动盖110a和第一折叠页410a的过程中，可以先将滑块120安装至第一折叠页410a的滑槽411中，使滑块120和滑槽411在前述长度方向上滑动配合，进而通过可拆卸连接件可以将第一移动盖110a固定在滑块120上，提升第一移动盖110a与第一折叠页410a之间的连接关系的可靠性。其中，滑槽411在前述长度方向上的尺寸和设置位置等参数，均可以根据第一移动盖110a和第一折叠页410a之间相对运动的最大值，以及第一移动盖110a和第一折叠页410a之间的初始位置确定，此处不作限定。
可选地，第一侧壁413和第二侧壁414上均设有滑槽411，也即，第一侧壁413朝向第二侧壁414的一侧，以及第二侧壁414朝向第一侧壁413的一侧均设有滑槽411，对应地，两个滑槽411均配设有滑块120，使第一移动盖110a的相背两端均能够通过滑块120与第一折叠页410a形成连接关系，这可以进一步提升第一移动盖110a与第一折叠页410a之间的配合稳定性。另外，
进一步地，如图7和图16所示，第一折叠页410a还包括配合部416，配合部416固定于承载部412，且配合部416位于第一侧壁413和第二侧壁414之间，配合部416设有滑槽411，也就是说，通过在第一侧壁413和第二侧壁414之间设置配合部416，且在配合部416上设置滑槽411，使得第一移动盖110a上位于相背两端之间的中间部分亦可以通过滑块120与第一折叠页410a相互连接，从而使第一移动盖110a的中部亦能够与第一折叠页410a形成较为稳定可靠性的限位连接关系，进一步提升第一移动盖110a和第一折叠页410a之间的配合稳定性。
具体地，配合部416的形状和尺寸可以根据实际需求确定，此处不作限定，并且，配合部416的数量亦可以为多个，通过使多个配合部416沿转轴200的轴向间隔设置在第一侧壁413和第二侧壁414之间，可以进一步提升第一移动盖110a和第一折叠页410a之间的配合稳定性。对应地，与配合部416连接的滑块120亦通过连接件可拆卸地与第一移动盖110a固定连接。
如上所述，随第一折叠页410a绕转轴组件800转动，第一移动盖110a能够相对第一折叠页410a移动，在第一移动盖110a远离第一折叠页410a的第三侧壁415的方向移动的过程中，第一移动盖110a与第三侧壁415之间会可能产生一定的间隙，从而导致折叠机构的封装效果降低。
可选地，通过使第一移动盖110a靠近第三侧壁415的端部的一部分设置为柔性材料，且使第一移动盖110a在长度方向上背离转轴200的一端边沿弯曲地伸入至第三侧壁415的内侧，且使第一移动盖110a存在一定的长度余量。在这种情况下，随着第一移动盖110a远离第三侧壁415，第一移动盖110a中前述伸入至第三侧壁415内侧的余量部分的一部分可以自第三侧壁415的内侧伸出，从而补偿第一移动盖110a远离第三侧壁415移动产生的尺寸差；对应地，在第一移动盖110a靠近第三侧壁415移动的过程中，第一移动盖110a的前述余量部分可以重新伸入且缩回至第三侧壁415的内侧，从而使前述余量部分被“储存”起来，保证折叠机构能够正常地进行折叠和展开，且可以使整个折叠机构的封装完整性较好。
在本申请的另一实施例中，可选地，如图20和图21所示，折叠机构还包括壳体130，壳体130与侧部连接，且壳体130与承载部412相对设置，壳体130与第一移动盖110a搭接配合。具体地，壳体130可以为平板状结构件，其与第一折叠页410a中的承载部412相对设置，二者通过侧部连接，且形成容纳空间，第一联动组件300a、滑块120和配合部416等结构可以设置在壳体130与承载部412之间，且第一移动盖110a的至少一部分位于承载部412和壳体130之间。其中，壳体130与侧部之间可以通过螺钉等连接件相互连接。另外，第二折叠页410b上亦可以设置有壳体130，在第二折叠页410b 和第一折叠页410a的结构相同，且第二移动盖110b和第一移动盖110a的结构相同的情况下，设置在第二折叠页410b上的壳体130的结构与设置在第一折叠页410a上的壳体130的结构相同。
在采用上述技术方案的情况下，壳体130与侧部，尤其是壳体130与第三侧壁415之间的密封连接性能更好，可以提升折叠机构的整体封装可靠性。并且，通过使壳体130与第一移动盖110a搭接配合，在第一移动盖110a与第三侧壁415的相对运动过程中，可以通过增大或减小第一移动盖110a和壳体130之间相互搭接的部分的尺寸保证第一移动盖110a能够向靠近第三侧壁415的方向移动，亦可以保证第一移动盖110a能够向远离第三侧壁415的方向移动。
可选地，第一移动盖110a包括相互连接的搭接部和对接部，至少部分搭接部位于壳体130和承载部412之间，在展开状态，对接部与壳体130对接且平齐设置。在采用前述方案的情况下，搭接部位于第一折叠页410a的承载部412和壳体130之间，而对接部则与壳体130平齐设置，从而在第一移动盖110a能够借助搭接部实现与壳体130相对运动的同时，还可以使折叠机构中背离承载部412的一侧具有较为平整的表面，也即在折叠机构处于展开状态的情况下，对接部的表面与壳体130的表面共面设置，从而使折叠机构的平整度相对更强，亦可以使电子设备的内部空间更大，且还可以在一定程度上提升折叠机构以及电子设备的外观性能。
如上所述，壳体130与第一折叠页410a之间可以通过螺钉等连接件连接，可选地，侧部设有支撑台440，壳体130搭接于支撑台440，在这种情况下，侧部可以为壳体130提供支撑作用，提升壳体130的受力性能，并且，还可以使侧部包围壳体130，进一步提升壳体130与第一折叠页410a之间的连接可靠性。在上述实施例中，穿过壳体130的连接件可以固定在支撑台440上，或者，还可以通过粘接等方式固定连接壳体130和第一折叠页410a，在设置有支撑台440的情况下，可以大幅提升壳体130与第一折叠页410a之间的接触面积，亦可以保证二者之间的粘接可靠性较高。
进一步地，沿承载部412的厚度方向，搭接部与支撑台440平齐，这使得第一移动盖110a与壳体130之间的搭接紧密度更高，进一步防止外界的灰尘等杂质自第一移动盖110a和壳体130之间的缝隙进入折叠机构。
如上所述，转轴组件800可以包括转轴或铰接件等，可选地，如图3-图7所示，转轴组件800包括连接座820和多个支撑条810，多个支撑条810并排设置。具体地，支撑条810的数量可以为两个、三个或更多个，且可以使多个支撑条810的尺寸相同，从而在弯折的过程中，使转轴组件800各个位置处的弯曲程度基本相同，且在电子设备的显示屏为柔性屏的情况下，使显示屏中与转轴组件800配合的区域中各位置处的被支撑效果基本相同，保证显示屏的被支撑效果较好。
可选地，支撑条810的数量为奇数，且大于3，在这种情况下，在转轴组件800转动变形的过程中，多个支撑条810中位于最中间的支撑条可以作为整个转轴组件800的旋转轴，从而使转轴组件800的旋转形态更对称，且进一步提升转轴组件800的支撑效果。具体来说，多个支撑条810中位于最中间的支撑条可以为固定支撑条，固定支撑条相背两侧的支撑条可以为旋转支撑条，且固定支撑条相背两侧分别设置有数量相同的旋转支撑条。另外，在支撑条810的数量较多的情况下，可以使每一个支撑条810的转动角度相对较小，从而使转轴组件800的弯折均匀性更强。
如图3和图4所示，相邻的两个支撑条810通过连接座820转动连接，具体地，连接座820可以为铰链，其通过与两个支撑条810固定连接，可以使两个支撑条810能够相对转动，连接座820和支撑条810之间可以通过粘接、焊接或连接件连接等方式相互连接，连接座820和支撑条810之间的连接方式可以包括搭接或套接等。更具体地，相邻的两个支撑条810之间可以通过一个连接座820连接，该连接座820可以设置在支撑条810的长度方向的中部，或者，两个支撑条810之间也可以通过多个连接座820连接，多个连接座820可以沿支撑条810的长度方向间隔分布，这可以提升两个支撑条810之间的连接可靠性。
本申请实施例公开的转轴组件800包括连接座和多个支撑条，相邻的两个支撑条通过连接座转动连接，从而使转轴组件800具备弯折变形的能力，且整个转轴组件800的结构较为简单，便于制造、组装，可以在一定程度上降低成本。
在通过上述转轴组件800连接第一折叠页410a和第二折叠页410b的过程中，位于转轴组件800第一侧的支撑条810与第一折叠页410a连接，位于转轴组件800第二侧的支撑条810与第二折叠页410b连接，第一侧和第二侧为转轴组件800中相背的两侧。如上所述，第一折叠页410a和第二折叠页410b的结构可以相同，为了便于描述，下文仅对第一折叠页410a与转轴组件800之间的连接关系进行描述，以供第二折叠页410b与转轴组件800之间的连接方式作为参考。
具体地，可以采用粘接或连接件连接等方式将支撑条810与第一折叠页410a连接在一起。更具体地，支撑条810与第一折叠页410a之间可以直接连接，亦可以通过其他结构间接地连接在一起，以满足不同需求。
基于上述实施例，本申请实施例公开的转轴组件800可以应用在电子设备中，位于转轴组件800相背两侧的支撑条810均与第一折叠页410a连接，从而使包括该转轴组件800的电子设备可以被折叠和被展开，在电子设备处于折叠状态的情况下，电子设备的整体尺寸相对较小，便于携带，在电子设备处于展开状态的情况下，展开面积相对较大，从而可以为电子设备配设面积较大的显示屏，使得电子设备具有较大的显示面积，这使得采用该转轴组件800的电子设备能够兼顾便携性和显示面积。
进一步地，如图5所示，各连接座820均可以设有两个轴向相同的定位孔821，连接座820包括连接座820，各支撑条810均设有第一连接轴850，相邻的两个支撑条810各自的第一连接轴850通过连接座820转动连接。也即，连接座820与支撑条810之间通过轴孔配合的方式形成转动连接关系，这使得支撑条810之间的连接关系较为可靠，且可以提升支撑条810与连接座820之间的配合稳定性。
具体地，第一连接轴850和定位孔821均可以为圆柱状结构，降低定位孔821与第一连接轴850之间的间隙，提升转动配合稳定性。可选地，第一连接轴850设置在支撑条810的端部，支撑条810的相背两端均可以设置有第一连接轴850，这使得连接座820能够连接两个支撑条810。或者，第一连接轴850可以设置在支撑条810的一侧，例如，第一连接轴850为弯折状结构，其一端连接在支撑条810的一侧，另一端与定位孔821插接配合，这也可以保证连接座820可以为相邻的两个支撑条810提供连接作用。
在第一连接轴850设置在支撑条810的一侧的情况下，可选地，如图3和图4所示，各所述支撑条810均配设设置有多个所述第一连接轴850，多个第一连接轴850沿第一连接轴850的轴向间隔设置。也即，相邻的两个支撑条810之间通过多个第一连接轴850和多个连接座820连接，这可以保证支撑条810上各处的连接可靠性均相对较高，且可以保证支撑条810之间的连接稳定性更高。
进一步地，如图5所示，各支撑条810均可以设有第二连接轴860，第二连接轴860的轴线与第一连接轴850的轴线平行。在采用上述技术方案的情况下，支撑条810与第一折叠页410a之间亦可以通过轴孔配合结构形成转动连接关系，从而使支撑条810和第一折叠页410a之间的连接和转动配合关系也较为可靠。相应地，在支撑条810的数量为至少三个的情况下，通过在支撑条810上同时设置第一连接轴850和第二连接轴860，使得支撑条810与位于其两侧的两个支撑条810之间，以及支撑条810与第一折叠页410a之间的连接可靠性均相对较高。
同时，第二连接轴860配设有连接座820，如上所述，连接座820设有两个定位孔821，在本实施例中，连接座820的两个定位孔821中的至少一者与第二连接轴860插接且转动配合。更详细地说，可以使两个第二连接轴860一一对应地插接于连接座820的两个定位孔821中，从而借助连接座820将两个相邻的支撑条810连接为一体；或者，连接座820的两个定位孔821中，一个定位孔821与第二连接轴860插接且转动配合，另一个与第一折叠 页410a转动连接，从而使支撑条810与第一折叠页410a之间的转动配合关系更稳定。可选地，与第一连接轴850连接的连接座820的两个定位孔821中，也可以一者与第一连接轴850连接，另一者与第一折叠页410a转动连接，以通过第一连接轴850和连接座820之间的连接关系，实现连接支撑条810和第一折叠页410a的目的。
如上所述，支撑条810上可以设置有第一连接轴850和第二连接轴860，可选地，第一连接轴850和第二连接轴860的形状和尺寸均可以对应相同，在这种情况下，同一连接座820既可以与第一连接轴850配合，也可以与第二连接轴860配合，从而可以降低连接座820和支撑条810的连接难度，提升组装效率。并且，第一折叠页410a与支撑条810之间亦可以通过轴孔连接结构相互连接，可选地，第一折叠页410a上亦可以设置有连接轴，在前述连接轴与第一连接轴850和第二连接轴860的形状和尺寸对应相同的情况下，转轴组件800中多个连接座820的形状和尺寸均可以对应相同，在这种情况下，可以仅配设一种型号的连接座820，一方面可以降低备件难度和成本，另一方面可以进一步降低转轴组件800的组装难度。
在支撑条810上设置有第一连接轴850和第二连接轴860的情况下，可选地，第一连接轴850和第二连接轴860均可以间隔设置在支撑条810的端部，通过多个连接座820，可以将多个支撑条810转动连接在一起。

基于上述实施例，可选地，如图5所示，支撑条810的一侧设置有第一容纳槽811，第一连接轴850设置在第一容纳槽811之内，在这种情况下，第一连接轴850不会伸出至支撑条810之外，从而在相邻的两个支撑条810相互连接时，可以使支撑条810之间的间隙更小，进一步提升转轴组件800 的支撑性能。对应地，与第一转动轴连接的连接座820的至少一部分可以容纳在第一容纳槽811之内。更具体地，如上所述，两个第一连接轴850可以通过一个连接座820转动连接为一体。基于上述技术方案，可选地，上述连接座820的一部分可以容纳于一个第一容纳槽811内，连接座820的另一部分可以容纳在另一个第一容纳槽811内，从而进一步减小支撑条810之间的间隙。当然，支撑条810和支撑条810之间需要预留一定的缝隙，以保证二者能够正常地相对转动。
具体地，第一容纳槽811可以通过挖孔的方式形成在支撑条810的一侧，且可以在形成第一容纳槽811的过程中，通过余留部分结构形成第一连接轴850；或者，也可以先在支撑条810上形成第一容纳槽811，之后，通过焊接或粘接等方式，在第一容纳槽811内固定第一连接轴850；或者，还可以通过在支撑条810上形成沿支撑条810的长度方向延伸的贯穿孔，且第一连接轴850可以自支撑条810的一端伸入，且固定于第一容纳槽811处。当然，第一容纳槽811和第一连接轴850的形成方式还有多种，考虑文本简洁，此处不再一一列举。

基于上述实施例，可选地，第一连接轴850和第二连接轴860中的至少一者的数量为多个，在这种情况下，可以进一步提升支撑条810之间，以及支撑条810与第一折叠页410a之间的连接可靠性。多个第一连接轴850和/ 或多个第二连接轴860沿支撑条810的长度方向延伸。
在支撑条810设有第一容纳槽811和第二容纳槽812的情况下，可选地，如图5所示，第一容纳槽811具有相对的第一槽壁811a和第二槽壁，第一连接轴850连接在第一槽壁811a，从而保证第一连接轴850与支撑条810之间能够形成有可靠的固定连接关系。第一连接轴850背离第一槽壁811a的一端在第一连接轴850的轴向上与第二槽壁之间设有第一预设间隔，也即，第二连接轴860不与第二槽壁相互连接。在组装支撑条810和连接座820的过程中，连接座820能够自第一预设间隔安装至第一连接轴850上，从而使连接座820能够与第一连接轴850形成稳定配合关系。

在本申请的另一实施例中，可选地，如图5所示，本申请实施例公开的转轴组件800还包括第一封堵部841和第二封堵部842，第一预设间隔内设置有第一封堵部841，也即，通过第一封堵部841填充第一预设间隙，在这种情况下，当连接座820通过第一预设间隙安装至第一连接轴850上之后，可以将第一封堵部841安装至第一预设间隙内，且使第一封堵部841与支撑条810连接，以在第一连接轴850的轴向，使第一封堵部841、(安装在第一连接轴850上的)连接座820和支撑条810限位配合，也即，第一封堵部841和连接座820可以被限位在第一容纳槽811的第一槽壁811a和第二槽壁之间。 采用上述技术方案，可以保证安装在第一连接轴850上的连接座820基本不会意外地自第一连接轴850上脱落，且由于第一封堵部841可以自第一容纳槽811的多个方向安装至第一预设间隙内，因此，第一封堵部841的安装难度也相对较小。
第二预设间隙内设置有第二封堵部842，沿第二连接轴860的轴向，第二封堵部842、(安装在第二连接轴860上)的连接座820和支撑条810限位配合，从而保证安装在第二连接轴860上的连接座820也不会意外自第二连接轴860上脱落，且可以降低封堵工作的完成难度。具体地，第一封堵部841和第二封堵部842的具体形状和尺寸可以根据第一预设间隙和第二预设间隙的具体尺寸对应确定，此处不作限定。另外，可以通过粘接、卡接或连接件连接等方式，将第一封堵部841和第二封堵部842固定在支撑条810上。可选地，第一封堵部841和第二封堵部842均通过可拆卸连接的方式与支撑条810连接，从而便于转轴组件800的维护和修理工作的进行。具体地，第一封堵部841和第二封堵部842均可以通过螺钉等连接件与支撑条810形成可拆卸地固定连接关系。
可选地，第一容纳槽811和第二容纳槽812成对设置，在这种情况下，如图5所示，第一封堵部841和第二封堵部842通过固定部843固定连接，三者组成堵头840，固定部843与支撑条810可拆卸地固定连接，从而在组装转轴组件800的过程中，可以一并完成第一封堵部841和第二封堵部842的安装工作，进而可以降低转轴组件800的组装难度，提升组装效率。并且，在上述实施例中，第一封堵部841和第二封堵部842均通过固定部843与支撑条810固定连接，亦可以提升转轴组件800的组装效率。
具体地，固定部843与支撑条810之间可以通过螺钉等连接件形成可拆卸地固定连接关系，固定部843的具体形状可以根据支撑条810的形状等参数确定。可选地，第一封堵部841、第二封堵部842和固定部843可以采用一体成型的方式形成，从而进一步提升转轴组件800的组装难度，且可以使三者之间的连接可靠性相对较高。
进一步地，支撑条810上可以设置有安装沉槽，固定部843可以设置在安装沉槽内，且与支撑条810可拆卸地固定连接，在这种情况下，可以在一定程度上增大固定部843的厚度，从而可以提升固定部843的结构强度和固定效果。具体地，安装沉槽的形状与固定部843的形状相同或相近，且二者的尺寸也相同。
如上所述，第一容纳槽811具有第一槽壁811a和第二槽壁，第一连接轴850连接在第一槽壁811a上，第二容纳槽812具有第三槽壁和第四槽壁812a，第二连接轴860连接在第三槽壁上。可选地，在第一连接轴850的轴向上，可以使第一槽壁811a和第三槽壁临近设置，也即，第二槽壁、第一槽壁811a、第三槽壁和第四槽壁812a沿第一连接轴850的轴向分布。
在本申请的另一实施例中，可选地，沿第一连接轴850的轴向，第二槽壁和第四槽壁812a位于第一槽壁811a和第三槽壁之间，也即，第一槽壁811a、第二槽壁、第四槽壁812a和第三槽壁沿第一连接轴850的轴向分布，在这种情况下，与第一连接轴850连接的连接座820和与第二连接轴860连接的连接座820在第一连接轴850的轴向之间的间隔相对更大，连接座820更为分散，从而使支撑条810之间，以及支撑条810与第一折叠页410a之间的各处的连接可靠性均相对较高。
如上所述，支撑条810和第一折叠页410a之间亦可以通过连接座820连接，支撑条810上可以设置有第一连接轴850和/或第二连接轴860，对应地，第一折叠页410a上也可以设置有连接轴，以与连接座820转动连接。
在本申请的另一实施例中，可选地，如图6和图7所示，转轴组件800还可以包括轴连接块830，轴连接块830包括固定连接的块本体831和第三连接轴832，块本体831可以与第一折叠页410a可拆卸地固定连接，第三连接轴832可以与连接座820的定位孔821插接且转动配合。采用上述技术方案的情况下，第一折叠页410a的结构相对规整，从而保证第一折叠页410a具有较高的防护作用，且由于第一折叠页410a可以通过轴连接块830间接地与转轴组件800相互连接，从而可以在一定程度上消除第一折叠页410a的结 构设计限制。
具体地，块本体831和第三连接轴832也可以采用一体成型的方式形成，以提升二者之间的连接强度。块本体831与第一折叠页410a之间可以通过可拆卸连接的方式固定连接为一体，以保证第一折叠页410a和转轴组件800之间可拆卸，便于对第一折叠页410a和转轴组件800进行维护。
基于上述任一实施例提供的折叠机构，本申请实施例还提供一种电子设备，其包括显示屏900和上述任一折叠机构，如图20所示，显示屏900支撑于折叠机构，且显示屏900位于第一折叠页410a背离第一移动盖110a的一侧。显示屏900具体可以为柔性屏，以保证显示面积的最大化。
在上述电子设备处于展开状态的情况下，其显示面积相对较大，在该电子设备处于折叠状态的情况下，可以在一定程度上提升便携性，从而使电子设备能够兼顾较大的显示面积和较好的便携性。
本申请实施例公开的电子设备可以为智能手机、平板电脑、电子书阅读器或可穿戴设备。当然，该电子设备也可以是其他设备，本申请实施例对此不做限制。
本申请上文实施例中重点描述的是各个实施例之间的不同，各个实施例之间不同的优化特征只要不矛盾，均可以组合形成更优的实施例，考虑到行文简洁，在此则不再赘述。
以上所述仅为本申请的实施例而已，并不用于限制本申请。对于本领域技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原理之内所作的任何修改、等同替换、改进等，均应包含在本申请的权利要求范围之内。
