具体实施方式
本实施例提供了一种坐蔸100，如图1-图2所示，该坐蔸100包括扶手组件1、蓬杆组件2、两个传动机构、可拆卸连接于主车架200的两个坐蔸接头、及锁紧机构6，其中传动机构包括设置于扶手组件1的第一侧的第一传动机构301和设置于扶手组件1的第二侧的第二传动机构302，第一传动机构301和第二传动机构302均包括坐杆31、第一连杆32及转动连接于蓬杆组件2的第二连杆33，第一传 动机构301的坐杆31的第一端转动连接于第一传动机构301的第一连杆32，第一传动机构301的坐杆31的第二端转动连接于蓬杆组件2的第一端，所述第二传动机构302的所述坐杆31的第一端转动连接于所述第二传动机构302的所述第一连杆32，第二传动机构302的坐杆32的第二端转动连接于蓬杆组件2的第二端，且扶手组件1的第一侧的端部同轴转动连接于第一传动机构301的第一连杆32和第二连杆33之间，扶手组件1的第二侧的端部同轴转动连接于第二传动机构302的第一连杆32和第二连杆33之间。两个坐蔸接头包括第一坐蔸接头41和第二坐蔸接头42，第一坐蔸接头41设置于第一传动机构301的坐杆31和蓬杆组件2之间，第二坐蔸接头42设置于第二传动机构302的坐杆31和蓬杆组件2之间，且第一传动机构301的坐杆31的转动轴、蓬杆组件2的第一端的转动轴及第一坐蔸接头41的转动轴同轴设置，第二传动机构302的坐杆31的转动轴、蓬杆组件2的第二端的转动轴及第二坐蔸接头42的转动轴同轴设置。锁紧机构6位于所述第一传动机构301和所述第二传动机构302中至少一个的所述坐杆31和蓬杆组件2之间，并设置为将所述第一传动机构301和所述第二传动机构302中至少一个的坐杆31和蓬杆组件2两者之间锁定和解锁。
通过蓬杆组件2与所述第一传动机构301和所述第二传动机构302中至少一个的坐杆31之间的锁紧机构解除坐杆31和蓬杆组件2之间的锁定，然后将蓬杆组件2和所述第一传动机构301和所述第二传动机构302的坐杆31向彼此靠近的方向转动靠拢，并带动所述第一传动机构301和所述第二传动机构302中的第一连杆32、第二连杆33及扶手组件1转动并向远离所述第一传动机构301和所述第二传动机构302中的坐杆31的方向延伸，实现了坐蔸100的折叠。由于第一坐蔸接头41和第二坐蔸接头42可拆卸连接于主车架200，采用这种方式，主车架200可以带着坐蔸100一起进行折叠，使得折叠后整体体积较小，便于用户存放和携带。尤其是需要运输时，占用空间小，有效的降低了运输成本。
如图1-图2所示，上述蓬杆组件2包括前蓬杆21和后蓬杆22，所述前蓬杆21的第一端转动销接于所述第一传动机构301的所述第二连杆33，所述前蓬杆21的第二端转动销接于所述第二传动机构302的所述第二连杆33；所述后蓬杆22的第一端同轴转动销接于所述第一传动机构301的所述坐杆31，所述后蓬杆22的第二端同轴转动销接于所述第二传动机构302的所述坐杆31。其中前蓬杆21的第一端的转动轴和第一传动机构301的第二连杆33的转动轴同轴设置，所述前蓬杆21的第二端的转动轴和所述第二传动机构302的第二连杆33的转动轴同轴设置，且该 前蓬杆21的转动轴设置于后蓬杆22上。同时后蓬杆22的第一端的转动轴、第一传动机构301的坐杆31的转动轴及第一坐蔸接头41的转动轴同轴设置；后蓬杆22的第二端的转动轴、第二传动机构302的坐杆31的转动轴及第二坐蔸接头42的转动轴同轴设置。由于扶手组件1分别同轴转动销接于上述的第一连杆32和第二连杆33，使得坐杆31、第一连杆32、第二连杆33及后蓬杆22，形成四杆连杆机构，实现坐蔸100的折叠。
如图7和图8所示，上述锁紧机构6包括：锁定齿61和锁定齿压簧62，所述后蓬杆22的端部与所述坐杆31的端部均设置有与锁定齿61相适配的齿槽，且后蓬杆22的齿槽和与所述坐杆31的齿槽相对设置，锁定齿61能够在后蓬杆22的齿槽和与所述坐杆31的齿槽内滑动；锁定齿压簧62设置在坐杆31的齿槽内，锁定齿61抵压锁定齿压簧62；上述锁紧机构6还包括：锁定齿顶块63、回位压簧64及按钮65，锁定齿顶块63及回位压簧64均位于后蓬杆22的端部内，且位于后蓬杆22的齿槽远离锁定齿61的一侧，按钮65滑动设置于后蓬杆22的端部上，按钮65设置有第一斜面，锁定齿顶块63设置有与第一斜面适配的第二斜面，复位弹簧设置于按钮65的底部。其中，后蓬杆22的端部指的是后蓬杆22的第一端和后蓬杆22的第二端中的至少一个；坐杆31的端部指的是第一传动机构和第二传动机构中至少一个的坐杆31的第二端。锁定齿61和锁定齿压簧62均套设在上述的后蓬杆22的端部和上述的坐杆31的端部转动轴上。
当后蓬杆22与坐杆31处于锁定状态时，锁定齿61的第一端置于后蓬杆22的齿槽内，锁定齿61的第二端置于坐杆31的齿槽内，此时，后蓬杆22与坐杆31不能发生相对转动。当按压按钮65时，按钮65滑动，回位压簧64被压缩，按钮65的第一斜面挤压锁定齿顶块63的第二斜面，从而使锁定齿顶块63推动锁定齿61在后蓬杆22的齿槽和所述坐杆31的齿槽内滑动，并压缩锁定齿压簧62，直至锁定齿61完全置于坐杆31端部的齿槽内，此时，后蓬杆22与坐杆31解锁，后蓬杆22与坐杆31可相对转动；当放开按钮65，在回位压簧64的作用下，按钮65复位，此时，锁定齿61在锁定齿压簧62的作用下，使锁定齿61在后蓬杆22的齿槽和所述坐杆31的齿槽内滑动，直至锁定齿压簧62复位，此时，锁定齿61的第一端置于后蓬杆22的齿槽内，锁定齿61的第二端置于坐杆31的齿槽内，后蓬杆22与坐杆31处于锁定状态。
为了提供放置空间，以提高舒适效果，该坐蔸100还包括U形结构的脚踏杆5，其中脚踏杆5的第一端转动连接于第一传动机构301的坐杆31和第一连杆32，且 脚踏杆5的第一端、第一传动机构301的坐杆31和第一连杆32三者的转动轴同轴设置；所述脚踏杆5的第二端转动连接于所述第二传动机构302的所述坐杆31和所述第一连杆32，且所述脚踏杆5的第二端及所述第二传动机构302的所述坐杆31和所述第一连杆32三者的转动轴同轴设置。
在一实施例中，在所述第一传动机构301和所述第二传动机构302中至少一个的所述坐杆31和脚踏杆5之间还设置有锁定件8，设置为将所述第一传动机构301和所述第二传动机构302中至少一个的坐杆31和脚踏杆5两者之间的锁紧和解锁。当坐蔸100需要折叠时，先解除上述的坐杆31和脚踏杆5之间的锁定，然后将脚踏杆5向靠近后蓬杆22的方向转动，以将脚踏杆5进行翻转折叠。当坐蔸100完成展开之后，将脚踏杆5转动至预设角度之后，将脚踏杆5和上述的坐杆31进行锁定，防止脚踏杆5转动，提高了安全性。
如图1-图2所示，为了增强整个坐蔸100结构的稳定性，该坐蔸100还包括两个设置于两个传动机构3之间的支撑杆组件7。其中支撑杆组件7包括第一支撑杆71和与第一支撑杆71平行设置的第二支撑杆72，第一支撑杆71、第二支撑杆72及两个坐杆31形成一个矩形框架结构。为了保证最佳的折叠效果，可以将脚踏杆5尽量翻转至该矩形框架结构所在的平面上，以节省整个坐蔸100结构的占用空间。在一实施例中，第一支撑杆71的第一端与脚踏杆5的转动轴的第一端同轴设置，所述第一支撑杆71的第二端与所述脚踏杆5的第二端同轴转动设置。第二支撑杆72的第一端分别与后蓬杆22的第二端的同轴设置。
如图7和图8所示，上述锁定件8包括卡簧81、卡齿82及按键83，脚踏杆5端部和坐杆31端部均设有与卡齿82相适配的卡槽，卡簧81设置于脚踏杆5端部的卡槽内，卡齿82抵压卡簧81，卡齿82能在脚踏杆5端部的卡槽和坐杆31端部的卡槽内滑动；按键83位于坐杆31端部的卡槽的原远离卡齿82的一侧，并可在坐杆31的端部内滑动，按键83上设置有斜面。其中，脚踏杆5端部为脚踏杆5的第一端和脚踏杆5中的第二端中的至少一个；坐杆31包括第一传动机构和第二传动机构中的至少一个的坐杆31。卡簧81和卡齿82均套设在上述的脚踏杆5端部和上述的坐杆31端部的转动轴上。
当脚踏杆5与坐杆31处于锁定状态时，卡齿82的第一端置于脚踏杆5的卡槽内，卡齿82的第二端置于坐杆31的卡槽内，此时，脚踏杆5与坐杆31不能发生相对转动。当按压按键83时，按键83在坐杆31的端部内滑动，并通过斜面挤压卡齿82，使卡齿82在脚踏杆5的卡槽和坐杆31的卡槽内滑动，并压缩卡簧81，直至 卡齿82完全置于脚踏杆5的卡槽内，此时，脚踏杆5与坐杆31解锁；当松开按键83，卡簧81复位，卡齿82在卡簧81的作用下，在脚踏杆5的卡槽和坐杆31的卡槽内滑动，直至卡齿82的第一端置于脚踏杆5的卡槽内，卡齿82的第二端置于坐杆31的卡槽内，脚踏杆5与坐杆31重新锁定。
本实施例提供坐蔸100的工作过程如下：
当坐蔸100需要折叠时，先将如图3所示处于展开状态的坐蔸100，通过锁定件8解除脚踏杆5和坐杆31之间的锁定，并将脚踏杆5向上翻转至接近支撑杆组件7和坐杆31所在的平面；然后通过锁紧机构6解除坐杆31和后蓬杆22之间的锁定，将上述坐杆31和后蓬杆22向彼此靠近的方向转动，形成如图4所示的坐蔸100半折叠状态；之后继续将后蓬杆22向坐杆31靠拢，即可将整个坐蔸100折叠至如图5所示的完全折叠状态。
当坐蔸100需要展开时，将脚踏杆5向下翻通过锁定件8将脚踏杆5和坐杆31进行解锁，同时将坐杆31和后蓬杆22向彼此远离的方向转动，并通过锁紧机构6将坐杆31和后蓬杆22进行锁定，即可将坐蔸100展开。
本实施例还提供了一种推车，如图6所示，该推车包括上述坐蔸100及主车架200，所述第一坐蔸接头41和第二坐蔸接头42可拆卸连接于所述主车架200上。
