下面结合附图及具体实施例对本申请再作进一步详细的说明。在本申请的描述中方位或位置关系为基于可折叠车辆正常使用的状态，需要理解的是，这些方位术语仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。
请参见图1和图2，本申请实施例一方面提供一种折叠机构，折叠机构100包括第一折叠件10、操控件20、第一转轴30、第二转轴40、连接件50以及第二折叠件60。操控件20包括用于施力的自由部21和与自由部21连接的锁止部22。第一转轴30与锁止部22连接。锁止部22可绕第一转轴30转动。第二转轴40与第一折叠件10连接。连接件50的一端与第一转轴30连接。连接件50的另一端与第二转轴40连接。连接件50可绕第二转轴40的轴线转动。第二折叠件60形成有与锁止部22相适配的凹槽60a。第二折叠件60与第一折叠件10枢接。锁止部22绕第一转轴30的转动方向上，具有锁止位置和解锁位置。锁止部22处于锁止位置时，锁止部22的部分外壁面与凹槽60a的槽壁面抵压配合，以将第一折叠件10与第二折叠件60锁止。锁止部22处于解锁位置时，锁止部22能够由凹槽60a内退出，以使第一折叠件10相对于第二折叠件60自由转动。
折叠机构100处于展开状态时，锁止部22容纳于凹槽60a内，锁止部22处于锁止位置，锁止部22的部分外壁面与凹槽60a的槽壁面抵压配合，第一折叠件10与第二折叠件60锁止。当需要解锁折叠机构100时，先对自由部21施加远离第一折叠件10的力，锁止部22绕第一转轴30转动，自由部21远离第一折叠件10，便于再对自由部21施加远离第二折叠件60的力，自由部21带动锁止部22远离第二折叠件60，锁止部22带动第一转轴30远离第二折叠件60，第一转轴30带动连接件50的一端远离第二折叠件60，连接件50的另一端绕第二转轴40的轴线转动，直到锁止部22由凹槽60a内退出，锁止部22处于解锁位置，第一折叠件10相对于第二折叠件60自由转动。第二折叠件60与第一折叠件10枢接，即，第二折叠件60远离凹槽60a的一侧与第一折叠件10远离第二转轴40的一侧枢 接，也就是说，第一折叠件10可以相对第二折叠件60向靠近第二折叠件60的方向转动，如此，实现折叠机构100的折叠功能。
当需要再次展开折叠机构100时，将第一折叠件10向远离第二折叠件60的方向转动，直至展开折叠机构100。此时，向自由部21先施加靠近第二折叠件60的力，自由部21带动锁止部22靠近第二折叠件60，锁止部22带动第一转轴30靠近第二折叠件60，第一转轴30带动连接件50的一端靠近第二折叠件60，连接件50的另一端绕第二转轴40转动，直到锁止部22容纳于凹槽60a内，第一折叠件10与第二折叠件60锁止。再对自由部21施加靠近第一折叠件10的力，以使锁止部22绕第一转轴30转动，自由部21靠近第一折叠件10。如此，便于将自由部21收纳起来，避免误触。
本申请实施例提供的折叠机构100结构简单，操作便捷。锁止部22可绕第一转轴30转动以使自由部21靠近或远离第一折叠件10，不仅便于对自由部21施力，还便于将自由部21收纳起来，避免误触。此外，锁止部22的部分外壁面与凹槽60a的槽壁面抵压配合，以将第一折叠件10与第二折叠件60锁止，锁止部22与凹槽60a的接触面积大，使得锁止部22与凹槽60a锁止效果更好，避免第一折叠件10与第二折叠件60锁紧后晃动。
可以理解的是，连接件50的另一端绕第二转轴40的轴线转动，实际上连接件50与第二转轴40共同相对于第一折叠件10转动。
在一实施例中，请参见图4，第二折叠件60上凹槽60a所在的一侧形成有第一容纳槽。第一折叠件10上第二转轴40所在的一侧形成有第二容纳槽。连接件50的部分可以容纳于第一容纳槽和第二容纳槽内。具体的，当锁止部22容纳于凹槽60a时，连接件50的部分容纳于第一容纳槽和第二容纳槽内。如此，便于锁止部22容纳于凹槽60a内。
在一实施例中，请参见图4，第一转轴30上形成有沿第一转轴30径向的通孔30a。连接件50包括连接杆51和位于连接杆51一端的紧固部52。连接杆51贯穿通孔30a。紧固部52用于限制连接杆51脱离第一转轴30。连接杆51远离紧固部52的一端与第二转轴40连接。由于连接杆51贯穿通孔30a，第一转轴30可以沿连接杆51移动，又由于第一转轴30可以带动锁止部22运动，因此，锁止部22可以沿连接杆51移动。如此，便于锁止部22进入凹槽60a内，还便于锁止部22和/或凹槽60a存在制造误差时，能够通过调节锁止部22的相对位置消除制造误差。
在一实施例中，请参见图4和图6，紧固部52与连接杆51螺纹连接。紧固部52为螺母，连接杆51与紧固部52的连接端为螺杆。如此，便于通过调节紧固部52与连接杆51从而调节锁止部22在连接杆51上的位置，即，可以通过调节紧固部52与连接杆51之间的距离从而调节锁止部22与第二转轴40之间的距离，进一步便于锁止部22进入凹槽60a内，还便于进一步通过调节锁止部22的相对位置消除制造误差。示例性的，当需要减小锁 止部22与第二转轴40之间的距离时，可以转动紧固部52以使紧固部52靠近第二转轴40，从而使得锁止部22靠近第二转轴40。当需要增大锁止部22与第二转轴40之间的距离时，可以转动紧固部52以使紧固部52远离第二转轴40，从而使得锁止部22远离第二转轴40。紧固部52与连接杆51螺纹连接，便于准确调节距离。
在另一未示出的实施例中，紧固部52与连接杆51为一体结构。如此，简化结构，易于制造。
在一实施例中，请参见图2和图6，第二折叠件60包括用于容纳紧固部52的沉台60b。紧固部52至少部分位于锁止部22的外部。由于紧固部52至少部分位于锁止部22的外部，便于调节紧固部52。沉台60b用于容纳紧固部52，避免紧固部52干涉锁止部22进入凹槽60a内。
在另一未示出的实施例中，紧固件52位于锁止部22的内部。如此，避免紧固部52干涉锁止部22进入凹槽60a内。
在一实施例中，请参见图1～图6，锁止部22为与凹槽60a的槽壁面曲面配合的偏心轮。
当需要锁止第一折叠件10和第二折叠件60时，向自由部21先施加靠近第二折叠件60的力，自由部21带动锁止部22靠近第二折叠件60。由于锁止部22为偏心轮，锁止部22半径较小的部分先进入凹槽60a内。如此便于通过施加较小的力使得锁止部22半径较小的部分先进入凹槽60a内。再对自由部21施加靠近第一折叠件10的力，锁止部22绕第一转轴30转动，锁止部22半径较大的部分进入凹槽60a内，锁止部22与凹槽60a的槽壁面曲面配合，第一折叠件10与第二折叠件60锁止。此种结构，使得锁止部22与凹槽60a的接触面积进一步增加，使得锁止部22与凹槽60a之间锁的更紧，避免第一折叠件10与第二折叠件60锁紧后松晃动。还能避免第一折叠件10与第二折叠件60在锁紧状态下，第一折叠件10受到靠近第二折叠件60的力时，锁止部22脱离凹槽60a，提高了安全性。
当需要解锁第一折叠件10和第二折叠件60时，先对自由部21施加远离第一折叠件10的力，锁止部22绕第一转轴30转动，锁止部22半径较大的部分先脱离凹槽60a。再对自由部21先施加远离第二折叠件60的力，自由部21带动锁止部22远离第二折叠件60，锁止部22半径较小的部分脱离凹槽60a。如此便于通过施加较小的力使得锁止部22脱离凹槽60a。第一折叠件10与第二折叠件60解锁。
在一实施例中，请参见图4和图6，连接件50与第二转轴40螺纹连接。此种设计，便于快速装配或拆卸连接件50和第二转轴40。示例性的，可以先将第二转轴40贯穿第一折叠件10的一侧，再将连接件50穿过第一转轴30的通孔30a后与第二转轴40以旋拧方式实现紧固连接，不仅提高了三者之间的连接稳定性，而且十分有利于三者之间的装配和拆卸作业，提高了折叠机构的拆装便捷性。
在一具体实施例中，第一转轴30贯穿锁止部22，连接件50的一端与第一转轴30连接，连接件50的另一端再与第二转轴40连接。连接件50的一端与第一转轴30连接，可以是第一转轴30上形成有沿第一转轴30径向的通孔30a，连接件50包括连接杆51和位于连接杆51一端的紧固部52，连接杆51远离紧固部52的一端贯穿通孔30a再与第二转轴40连接。紧固部52能够限制连接杆51脱离第一转轴30即可。连接杆51与紧固部52可以是一体式结构，连接杆51也可以与紧固部52固定连接。连接杆51还可以与紧固部52螺纹连接。连接杆51远离紧固部52的一端可以与第二转轴40可拆卸式连接，例如螺纹连接。如此，可将锁止部22、连接件50和第二转轴40连接起来。
在一实施例中，请参见图1～图6，折叠机构100包括卡扣70以及卡接件80。卡扣70包括卡体71和与卡体71连接的卡接部72。卡体71与自由部21转动连接。卡接件80位于第一折叠件10上。卡接部72能够与卡接件80卡接，以使自由部21与第一折叠件10锁止。如此，进一步加强操控件20与第一折叠件10之间的连接，从而进一步锁紧第一折叠件10与第二折叠件60。使得折叠机构100更加牢固可靠。
在一实施例中，请参见图1，卡接件80包括与第一折叠件10连接的卡接体(图未示出)和从卡接体(图未示出)向远离第一折叠件10的方向延伸的自由端(图未示出)。卡接部72朝向自由部21的端面能够与自由端背离自由部21的端面抵接，以使卡接部72能够与卡接件80卡接。可以转动卡体71，使得卡接部72朝向自由部21的端面能够与自由端背离自由部21的端面抵接，此时卡接部72与卡接件80卡接。自由部21处于锁紧状态。当需要解锁时，向相反的方向转动卡体71，使得卡接部72朝向自由部21的端面与自由端背离自由部21的端面分离，以使卡接部72能够脱离卡接件80。自由部21处于解锁状态。
在一未示出的实施例中，卡接件80为沉槽。沉槽由第一折叠件10的外表面向内凹陷形成。卡接部72能够容纳于沉槽内，以使卡接部72能够与卡接件80卡接。可以转动卡体71，使得卡接部72能够容纳于沉槽内，此时卡接部72与卡接件80卡接。自由部21处于锁紧状态。当需要解锁时，向相反的方向转动卡体71，使得卡接部72脱离沉槽，以使卡接部72能够脱离卡接件80。自由部21处于解锁状态。
请参见图3～图6，本申请实施例另一方面提供一种可折叠车辆，可折叠车辆1000包括上述任意一项实施例中的折叠机构100。
在一实施例中，可折叠车辆1000包括立杆200和前叉300。立杆200和前叉300其中之一与第一折叠件10连接。立杆200和前叉300其中另一与第二折叠件60连接。在一具体实施例中，请参见图2，立杆200与第一折叠件10连接。前叉300与第二折叠件60连接。在另一具体实施例中，前叉300与第一折叠件10连接。立杆200与第二折叠件60连接。
可以理解的是，立杆200可以为空心管，也可以为实心管。立杆200的横截面可以为圆形、椭圆形，也可以为多边形。例如，三边形、四边形、五边形、六边形等。本申请实施例并不予以限制。
立杆200或前叉300与第二折叠件60和第一折叠件10之间的连接，可以是立杆200与第一折叠件10螺纹连接，或是立杆200与第二折叠件60螺纹连接。也可以是前叉300与第一折叠件10螺纹连接，或是前叉300与第二折叠件60螺纹连接。还可以是，立杆200与第一折叠件10通过卡箍连接，或立杆200与第二折叠件60通过卡箍连接。也可以是前叉300与第一折叠件10通过卡箍连接，或前叉300与第二折叠件60通过卡箍连接。
以本申请实施例提供的可折叠车辆为可折叠滑板车为例。本申请实施例提供的可折叠滑板车还可以包括前轮、踏板以及后轮。前轮设置于前叉上。前轮上可以设置挡泥板。挡泥板可以与前叉连接。踏板用于踏脚。后轮设置于踏板远离前轮的一端。后轮上也可以设置挡泥板，挡泥板可以与踏板连接。使用者可以一只脚站立在踏板上，另一只脚踩在地面上且向后轮方向施力，如此，可折叠滑板车可向前运动。
在一实施例中，可折叠滑板车可以包括与立杆连接的横把。横把便于使用者控制方向。
在一实施例中，可折叠滑板车可以包括用于照明的前灯。前灯可以设置在立杆、横把或前叉上。
在一实施例中，可折叠滑板车可以包括用于驱动前轮和/后轮的电源。如此，使用者可以双脚站立在踏板上。通过电源驱动可折叠滑板车运动。
本申请实施例提供的可折叠车辆还可以为可折叠自行车、可折叠平衡车等。本申请实施例提供的折叠机构100可以用于可折叠车辆的其他机构中，例如，用于可折叠自行车的车座中，便于车座的折叠收纳。
本申请实施例提供的折叠机构100也可以用于其他需要折叠的装置。
以上所述，仅为本申请的具体实施方式，但本申请的保护范围并不仅限于此，任何熟悉本技术领域的技术人员在本申请揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本申请的保护范围之内。因此，本申请的保护范围应以所述权利要求的保护范围为准。
