具体实施方式
需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的技术特征可以相互组合，具体实施方式中的详细描述应理解为本申请宗旨的解释说明，不应视为对本申请的不当限制。
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或滑板车正常使用的状态，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包括安装座10、支架20、限位轴40以及操控件50。安装座10形成有凹槽10a。支架20与安装座10枢转连接。支架20上形成有腰形孔20a。限位轴40位于支架20中，能够沿腰形孔20a滑 动。操控件50的一端与限位轴40连接，操控件50能够使限位轴40沿腰形孔20a滑动，以使限位轴40容纳于凹槽10a内或脱离凹槽10a，从而使支架20能够相对于安装座10固定或转动。
对操控件50施力，由于操控件50的一端与限位轴40连接，力传导至限位轴40上，限位轴40沿腰形孔20滑动，从而改变限位轴40在支架20上的位置。限位轴40容纳于凹槽10a内，同时，限位轴40也位于腰形孔20a内，此时，限位轴40在凹槽10a的作用下，限制支架20相对于安装座10转动，也就是说，支架20相对于安装座10处于第一状态。当需要改变支架20与安装座10的状态时，对操控件50施力，限位轴40沿腰形孔20滑动，直至限位轴40脱离凹槽10a，此时，凹槽10a失去对限位轴40的限位作用，支架20能够相对于安装座10转动，如此，支架20相对于安装座10处于第二状态。
本申请实施例提供的折叠机构100，通过控制操控件60使限位轴40沿腰形孔20a滑动，以使限位轴40容纳于凹槽10a内或脱离凹槽10a，从而使支架20能够相对于安装座10固定或转动，折叠机构100结构简单，操作便捷。
需要说明的是，本申请实施例中的第一状态是指支架20相对于安装座10处于展开状态。第二状态是指支架20相对于安装座10处于折叠状态。
具体的，腰形孔20a位于第二安装孔20b远离安装座10的一侧。
在一实施例中，请参见图2和图7，折叠机构100包括设置在安装座10上的预紧件60。限位轴40容纳于凹槽10a内时，预紧件60的至少部分位于安装座10和支架20之间。安装座10与支架20之间需要留存安装间隙，以便支架20相对安装座10转动。通过在安装座10上设置预紧件60，限位轴40容纳于凹槽10a内时，支架20相对于安装座10处于第一状态，此时，预紧件60的至少部分位于安装座10和支架20之间，预紧件60可以填充安装座10与支架20之间的安装间隙，避免安装座10和支架20处于第一状态时，安装座10和支架20相对晃动。
可以理解的是，预紧件60的至少部分位于安装座10和支架20之间，可以是预紧件60的部分位于安装座10和支架20之间，也可以是预紧件60的全部位于安装座10和支架20之间。
具体的，预紧件60包括但不限于橡胶、硅胶或软塑料。
在一实施例中，请参见图1、图2和图5，安装座10包括安装件11以及支撑件12。安装件11形成第一安装孔10b。支撑件12包括支撑板121和与支撑板121连接的限位板122。支撑板121与安装件11连接，预紧件60安装在支撑板121上，限位板122配置为对预紧件60限位。凹槽10a包括对应形成在安装件11上的第一凹槽11a和形成在支撑件12上的第二凹槽12a，第一凹槽11a和第二凹槽12a的形状相适配。如此，便于装卸预紧件60、 安装件11以及支撑件12。
在一具体实施例中，预紧件60形成有第三安装孔，支撑板121形成有与第三安装孔相适配的凸出部，凸出部套设在第三安装孔内。如此，不仅便于安装预紧件60，还可以避免预紧件60移动。
在一些实施例中，限位板122的形状与预紧件60相适配。示例性的，预紧件为圆柱体，限位板122的形状与预紧件60相适配，限位板122可以为圆弧板。如此，更好的限定预紧件60的位置。
在一实施例中，请参见图2和图5，折叠机构100包括弹性件70。弹性件70位于支架20内。弹性件70的一端与限位轴40连接，弹性件70的另一端与支架20连接。对操控件50施力，由于操控件50的一端与限位轴40连接，力传导至限位轴40上，限位轴40沿腰形孔20滑动，由于弹性件70的一端与限位轴40连接，弹性件70在拉力的作用下发生弹性形变，直至限位轴40脱离凹槽10a，可以释放操控件50，此时，弹性件70恢复形变，限位轴40在弹性件70的作用下靠近安装座10，也就是说，通过弹性件70使得限位轴40平缓复位。限位轴40容纳于凹槽10a时，由于弹性件70存在弹性形变，弹性件70的一端与限位轴40连接，弹性件70的另一端与支架20连接，则需要对限位轴40施加较大且朝远离安装座10方向的力才能使得限位轴40沿腰形孔20滑动，只有对限位轴40持续施加上述方向的力才能使得限位轴40脱离凹槽10a，因此，弹性件70还可以避免限位轴40被误触之后，限位轴40脱离凹槽10a。
在一实施例中，如图2所示，安装座10的位于凹槽10a的位置处的外表面为导向曲面，这样设置是为了使限位轴40在脱离凹槽10a后，使得导向曲面起到对限位轴40的支撑导向作用，不仅防止限位轴40被尖端磨损，而且便于支架20由第一状态向第二状态运动。此外，当使用者需要展开可折叠车辆，使用者能够转动支架20，支架20由第二状态向第一状态运动的过程中，导向曲面同样起到了对限位轴40的支撑导向作用，便于限位轴40顺利进入凹槽10a而被限位，从而便于使用者对可折叠车辆的操作，提升了可折叠车辆的使用便捷性。
在一实施例中，请参见图2～图5，支架20包括一端开口的架体21和盖合在架体21的开口上的端盖22。架体21和端盖22围设形成容纳腔20c。弹性件70位于容纳腔20a内。如此，可将弹性件70隐藏起来，不仅外观美观，还能保护弹性件70。
在一实施例中，请参见图2和图5，支架20包括位于容纳腔20c内的连接轴23。连接轴23与架体21连接。弹性件70的另一端与连接轴23连接。如此，便于弹性件70分别连接限位轴40和连接轴23。
具体的，弹性件70可以为弹簧。在一些实施例中，限位轴40形成有第一定位槽，连 接轴23形成有第二定位槽，弹性件70的一端位于第一定位槽内，弹性件70的另一端位于第二定位槽内。在一具体实施例中，第一定位槽沿限位轴40周向延伸，第一定位槽可以为环形槽，第二定位槽沿连接轴23的周向延伸，第二定位槽也可以为环形槽，弹性件70为弹簧，弹性件70的两端分别弯曲形成为弯曲端，弹性件70的两端分别位于第一定位槽和第二定位槽内，如此，实现弹性件70的一端与限位轴40连接，弹性件70的另一端与连接轴23连接。
在一实施例中，连接部51的一端形成有安装槽，限位轴40位于安装槽内，连接部51可以带动限位轴40运动。具体的，连接部51可以为拨叉。
在一实施例中，折叠机构100包括位于限位轴40上的至少两个止板，止板中的至少两个位于支架20的内侧或止板中的至少两个位于支架20的外侧。止板用于限制限位轴40沿轴向运动，避免限位轴40脱离支架20。
在另一未示出的实施例中，架体21上形成有通孔，弹性件70的一端穿过通孔，如此，实现弹性件70的一端与支架20连接。
在一实施例中，请参见图2和图5，安装座10上形成有第一安装孔10b。支架20上形成有第二安装孔20b。折叠机构100还包括连接第一安装孔10b和第二安装孔20b的转轴30，其中，转轴30与端盖22连接。如此，便于定位、组装架体21和端盖22。
具体的，转轴30可以为对锁螺栓。
在另一实施例中，架体21与端盖22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1～图3，操控件50包括连接部51以及施力部52。连接部51与支架20枢接。连接部51的一端与限位轴40连接。施力部52与连接部51的另一端枢接，施力部52位于支架20外。
可以对施力部52施加朝向支架20方向的力，由于连接部51与支架20枢接，力传递至连接部51上，连接部51再传递至限位轴40上，限位轴40受到远离支架20方向的力，如此，通过对施力部52施力，使得限位轴40沿腰形孔20a滑动。此种施力方式，便于使用者的施力。由于施力部52与连接部51的另一端枢接，也就是说，施力部52相对于连接部51可以转动，如此设计，便于将施力部52收纳起来，避免误触施力部52，还便于美化外观。
在另一未示出的实施例中，操控件50与支架20滑动连接。操控件50受力相对支架20滑动，带动限位轴40沿腰形孔20a滑动。如此，限位轴40的受力方向与操控件50的受力方向一致。
在一实施例中，请参见图1～图5，连接部51包括用于阻挡施力部52朝靠近安装座10运动的凸出端511。由于施力部52与连接部51的一端枢接，通过凸出端511阻挡施力部 52朝靠近安装座10运动，具体的，可以是施力部52朝靠近安装座10方向转动，当施力部52与凸出端511抵接，凸出端511向施力部52产生反作用力，如此，凸出端511阻挡施力部52继续朝靠近安装座10方向运动。此种设计，结构简单，便于施加在施力部52上的力传递至连接部51，连接部51再传递至限位轴40上，如此，通过对施力部52施力，使得限位轴40沿腰形孔20a滑动。
在一实施例中，请参见图1，操控件50包括设置于施力部52外表面的防滑层53。防滑层53增加摩擦力，从而便于对施力部52施力。具体的，防滑层622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52的外表面设置为防滑表面。防滑表面可以是对施力部52进行磨砂处理形成。也可以是在施力部52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52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53可以位于施力部52受力的端面，也可以位于施力部52的整个外表面。
在一实施例中，请参见图2和图5，安装座10为两个。两个安装座10分别位于支架20的两侧。此种设计，便于安装座10与支架20之间的装卸。
请参见图3～图7，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包括车头200、踏板300以及上述任意一项实施例中的折叠机构100。支架20远离安装座10的一端与车头200连接。安装座10与踏板300连接。
由于支架20能够相对于安装座10固定或转动，支架20相对于安装座10可以处于第一状态即展开状态，支架20相对于安装座10可以处于第二状态即折叠状态，也就是说，车头200相对于踏板300可以处于第一状态即展开状态，车头200相对于踏板300可以处于第二状态即折叠状态。
本申请实施例提供的可折叠车辆1000，支架20远离安装座10的一端与车头200连接。安装座10与踏板300连接。操控件50位置较为靠近使用者腿部位置，便于使用者脚踏操控件50施力，也就是说，在对操控件50施力时，可以通过脚踏操控件50的方式施力，此时，可以手扶车头200以将车头200相对于踏板300折叠，避免车头200在重力作用下倒下造成危险。当然，也可以通过手部对操控件60施力。使用者对操控件60的施力方式不限。

另一实施例中，与上述实施例不同的地方在于，脚踩板150形成有通孔100a以及至少一个第一螺纹孔200a，连接件140形成有与通孔100a连通的第二螺纹孔300a。
一具体实施例中，请参见图11，脚踩板150具有缺口，连接件140具有位于缺口内的凸出部，通孔100a以及一个第一螺纹孔200a形成于凸出部上，脚踩板150形成有与通孔100a连通的第二螺纹孔300a，转轴160穿设于第二螺纹孔300a和通孔100a内，阻尼杆170包括与第一螺纹孔200a相适配的第一螺杆171、以及与第二螺纹孔300相适配的第二螺杆172，第一螺杆171的数量与第一螺纹孔200a的数量相同，第二螺纹孔300a沿转轴160的轴向上具有两个开口，第二螺杆172的数量为两个；两个第二螺杆172分别从两个开口伸入第二螺纹孔300a内，且两个第二螺杆172分别与转轴160沿其轴向的两个端面抵接；第一螺杆171伸入第一螺纹孔200a内与转轴160的圆周面抵接。

一实施例中，脚踩板150位于施力位置时，脚踩板150的受力面150a与滑板车的支撑面之间的最大距离在10cm～20cm之间。示例性的，脚踩板150的受力面150a与滑板车的 支撑面之间的最大距离可以为10cm、11cm、12cm、13cm、14cm、15cm、16cm、17cm、18cm、19cm或20cm等等，如此，用户只需要稍微抬起脚部即可将脚部放置于脚踩板150上，省时省力。
需要说明的是，滑板车的支撑面是指用于支撑滑板车的基面。示例性的，支撑面包括但不限于地面、货架的承载面等等。脚踩板150的受力面150a与滑板车的支撑面之间的最大距离通常是指支撑面为大致平滑的平面时，脚踩板150的受力面150a与滑板车的支撑面之间的最大距离。
一实施例中，请参见图8和图9，踏板组件110包括踏板111、以及与踏板111的前端连接的安装座112，车头组件120包括前叉221以及支杆222，滑板车包括与前叉221转动连接的前轮180、以及与踏板111的后端转动连接的后轮，支杆222的一端与前叉221的下部连接，支杆222的另一端与所述安装座112转动连接，如此，车头组件120能够相对于踏板组件110转动；连接件140与支杆222转动连接，锁定件130、以及脚踩板150形成以连接件140的转动中心为杠杆支点的杠杆结构，脚踩板150位于施力位置时，对脚踩板150施加向下的作用力，脚踩板150能够驱动锁定件130向上运动以释放车头组件120。支杆222的一端与前叉221的下部连接，如此，脚踩板150所在的高度相对较低，用户只需要稍微抬起脚部即可将脚部放置于脚踩板150上，省时省力。锁定件130、以及脚踩板150形成以连接件140的转动中心为杠杆支点的杠杆结构，便于用户脚踩脚踩板150向下施力，锁定件130向上运动以释放车头组件120，进一步方便用户使用，提高体验感。
具体的，支杆222与前叉221连接包括但不限于焊接或铆接，支杆222与前叉221还可以一体成型。安装座112与踏板111连接包括不限于焊接或铆接，安装座112与踏板111也可以一体成型。
一实施例中，前轮180上可以设置挡泥板。挡泥板可以与前叉221连接。后轮上也可以设置挡泥板，挡泥板可以与踏板111连接。踏板111用于踏脚。使用者可以一只脚站立在踏板111上，另一只脚踩在地面上且向后轮方向施力，如此，滑板车可向前运动。
一实施例中，滑板车可以包括把手，把手与前叉221远离前轮180的一端连接。
一实施例中，滑板车可以包括用于照明的前灯。前灯可以设置在前叉221或把手上。
在一实施例中，滑板车可以包括用于驱动前轮180和/后轮的电源。如此，用户可以双脚站立在踏板111上。通过电源驱动滑板车运动，手握把手控制前进方向，电源驱动前轮180和/后轮转动。
一实施例中，请参见图8～图10，锁定件130包括位于支杆222内的限位轴131，连接件140远离脚踩板150的一端与限位轴131连接，限位轴131、以及脚踩板150形成以连接件140的转动中心为杠杆支点的杠杆结构，安装座112靠近前叉221的端部形成有凹槽 112a，支杆222对应凹槽112a所在处形成有腰形孔222a；限位轴131穿过腰形孔222a伸入凹槽112a内，以将车头组件120锁定在展开状态；在脚踩板150位于施力位置时，对脚踩板150施加向下作用力，脚踩板150能够使限位轴131沿腰形孔222a滑动，以使限位轴131脱离凹槽112a，从而释放车头组件120。
限位轴131穿过腰形孔222a伸入凹槽112a内，以将车头组件120锁定在展开状态，也就是说，限位轴131容纳于凹槽112a内，同时，限位轴131也位于腰形孔222a内，此时，限位轴131在凹槽112a的作用下，限制支杆222相对于安装座112转动，如此，将车头组件120锁定在展开状态；当需要释放车头组件120，也就是说，需要支杆222能够相对于安装座112转动，则施力使脚踩板150由稳定的收纳位置转动至施力位置，继续对脚踩板150施加向下作用力，由于限位轴131、以及脚踩板150形成以连接件140的转动中心为杠杆支点的杠杆结构，力传导至限位轴131上，限位轴131沿腰形孔222a向上滑动，使得限位轴131脱离凹槽112a，从而释放车头组件120，车头组件120能够在展开状态和折叠状态之间切换。
如此，通过控制脚踩板150使限位轴131沿腰形孔222a滑动，以使限位轴131容纳于凹槽112a内或脱离凹槽112a，从而使支杆222能够相对于安装座112固定或转动，从而将车头组件120锁定在展开状态或释放车头组件120，结构简单，操作便捷。
一实施例中，请参见图8，脚踩板150位于收纳位置时，脚踩板150朝向支杆222的端面贴合支杆222。脚踩板150位于收纳位置时，脚踩板150朝向支杆222的端面就是脚踩板150的受力面150a，如此设计，使得脚踩板150能够尽可能贴近支杆222，进一步避免用户误触。
一实施例中，请参见图11，连接件140具有拨叉部，限位轴131设置于拨叉部的叉口内。
一具体实施中，请参见图11，连接件140为一体成型结构，脚踩板150为一体成型结构。
一实施例中，请参见图8～图10，滑板车包括位于支杆222内弹性件，弹性件的一端与限位轴131连接，弹性件的另一端与支杆222连接。弹性件提供限位轴131回复至凹槽112a内的作用力。限位轴131容纳于凹槽112a时，对脚踩板150向下施力，限位轴131沿腰形孔222a滑动，弹性件发生弹性形变，直至限位轴131脱离凹槽112a，可以释放脚踩板150，此时，弹性件恢复形变，使得限位轴131平缓复位至凹槽112a内。由于弹性件存在弹性形变则需要对限位轴131施加较大且朝远离安装座112方向的力才能使得限位轴131沿腰形孔222a滑动，因此，弹性件还可以避免限位轴131被误触之后，限位轴131脱离凹槽112a，提高安全性。具体的，弹性件可以为拉簧。
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。
