基于以上结构，该轮椅的折叠过程主要通过连接于座椅本体2和后轮机构3之间的伸缩装置1来实现，当伸缩装置1做伸长运动时，其能够带动座椅本体2和后轮机构3在两前轮组件4的支撑件41之间做相对的运动，二者均向两个支撑件41之间靠拢，则此时座椅本体2向下翻转直至座位完全立起，后轮组件32则向前转动直至与前轮组件4相互重叠，由此将轮椅完全折叠；当伸缩装置1做缩短运动时，其能够带动座椅本体2和后轮机构3在两前轮组件4之间做相背的转动，二者分别从两个前轮组件4的支撑件41之间展开，则此时座椅本体2向上翻转直至座位恢复水平，后轮组件32向后转动至完全打开，由此将轮椅展开至正常使用状态。伸缩装置1的伸长和缩短始终保持在一个方向上，座椅本体2和后轮组件32在收起或者展开时，既在两前轮组件4之间进行转动，也分别相对于伸缩装置1的两端部进行转动，转动运动能够使得整个折叠操作更加顺畅，使用者在整个操作过程中更加省力。整个过程非常简单，折叠方便，便于年龄较大的患者或残疾人自主使用，折叠后，座椅本体2和后轮组件32全部位于两前轮组件4之间，整体体积非常小，占用空间较少，方便进行收纳放置。该轮椅结构的设计非常简单，外形简洁美观。
其中，座椅本体2包括坐部21和倚靠部22，坐部21可转动地连接于两前轮组件4之间，伸缩装置1的第一端部与坐部21的底部可转动地连接，座椅本体2的折叠通过伸缩装置1对坐部21的推拉来实现；倚靠部22可转动的连接于坐部21上，在平时使用状态下，倚靠部22垂直连接于坐部21的后侧，折叠时，伸缩装置1推动坐部21向下翻转至完全立起，再将倚靠部22向下翻转至与坐部21相互重叠，由此实现对座椅本体2的完全折叠，使其位于两前轮组件 4之间，占用空间更小。坐部21的底部设有第一限位槽211，后轮机构3包括后轮组件32和第一连接件31，第一连接件31的底端与后轮组件32固定连接，第一连接件31的顶端与两个前轮组件4的支撑件41可转动地连接，且轮椅在展开状态下，第一连接件31的顶端定位于第一限位槽211内，由此后轮机构3的第一连接件31既能够实现将后轮组件32可转动地连接于两个前轮组件4的支撑件41之间，又能够在轮椅展开时，对坐部21进行可靠有效的支撑，使得整个轮椅在使用过程中更加稳定。坐部21通过第一连接轴5可转动地连接于两个前轮组件4的支撑件41之间，支撑件41能够在两侧对坐部21进行支撑，第一连接轴5依次穿过左侧的支撑件41、坐部21和右侧的支撑件41，使得坐部21的转动非常可靠，坐部21折叠后位于两侧的支撑件41之间，且其两侧均与支撑件41保持平行；伸缩装置1的第一端部可转动地连接于坐部21的底部，且伸缩装置1的第一端部位于坐部21与两个前轮组件4连接处的后侧，从而能够保证伸缩装置1在伸长或者缩短时，推动坐部21相对于两个支撑件41进行转动的运动更加可靠。坐部21的底部的第一限位槽211内设有两个连接座6，两个连接座6上分别设有相对布置的定位孔61，两个定位孔61之间可转动地穿设有第二连接轴7，伸缩装置1的第一端部与第二连接轴7垂直相连接，更加方便伸缩装置1对坐部21的驱动，连接座6的设置能够保证第二连接轴7的转动更加可靠。需要说明的是，在本实施例中，支撑件41采用的是支撑板，支撑件41的底端设有卡槽，第一轮体42可转动地嵌设于卡槽内，支撑件41的上部设有供手指穿过的通孔412，使得支撑件41的顶部形成供使用者放置手臂的扶手411，当轮椅整体完成折叠后，使用者能够通过扶手411推动第一轮体42进行转动，由此对轮椅进行运输和转移，既方便又省力。前轮组件4的结构设计非常简洁，使得该轮椅的整体外形更加美观。
另外，伸缩装置1的第二端部与第一连接件31的底端可转动地连接，伸缩装置1的伸长或者缩短带动第一连接件31的顶端在两支撑件41之间进行转动，进一步的，由第一连接件31带动后轮组件32向前轮组件4靠近或者远离，由此实现对后轮组件32的折叠或展开。第一连接件31上设有开口朝向前侧的连接槽311，连接槽311的下端与后轮组件32固定连接，且连接槽311的两侧壁之间设置有第三连接轴8，伸缩装置1的第二端部与第三连接轴8垂直相连接，轮椅在展开状态下时，伸缩装置1整体位于连接槽311内，通过第三连接轴8 带动后轮组件32相对于伸缩装置1转动，保证后轮组件32折叠的可靠性。连接槽311的上端可转动地连接于两个前轮组件4的支撑件41之间，连接槽311的上端的两侧边上分别连接有与支撑件41相对布置的连接板312，连接板312和与其相对的支撑件41之间可转动地穿设有第四连接轴9，连接板312的设置能够保证连接槽311通过第四连接轴9在两支撑件41之间的转动更加顺畅，也更加方便带动连接槽311转动，轮椅在展开状态时，连接板312与坐部21相互垂直，能够对坐部21进行可靠的支撑。连接槽311的槽口朝向前侧，槽底朝向后侧，由此，在轮椅完全展开，伸缩装置1处于收缩状态时，其能够完全位于连接槽311内，连接板312完全没入第一限位槽211内，连接槽311和第一限位槽211相互配合，能够将伸缩装置1及与其之间的连接关系进行遮挡，使得整个轮椅的外露机构明显减少，保证整体外形的简洁和美观。参见图1至图4，后轮组件32包括第二连接件321和分别安装于第二连接件321的两端的第二轮体322，第一连接件31与第二连接件321固定连接，第二轮体322在第一连接件31对第二连接件321的推拉控制下进行转动，后轮组件32在折叠过程中在第二轮体322的转动带动下向前轮组件4靠拢，非常省力。其中，两个第二轮体322之前的距离小于两侧的第一轮体42之间的距离，将后轮机构3折叠至第二轮体322与第一轮体42相互重叠时，第二轮体322位于两侧的第一轮体42之间，由此，能够使整个轮椅折叠后，所有结构均叠至左右两侧的支撑件41之间，折叠后的体积非常小，方便收纳，且在对折叠后的轮椅进行移动时，通过推动扶手411，能够驱动第一轮体42和第二轮体322同时转动，方便折叠轮椅的运输和转移。
进一步的，坐部21的底部的第一限位槽211的两侧分别设有与第四连接轴9相对应的第二限位槽212，轮椅在打开状态下时，第四连接轴9位于第二限位槽212内，从而在打开状态下时，第二限位槽212能够为第四连接轴9提供相应空间进行限定，保证第四连接轴9的顺畅运行，并能够将其进行完全的遮挡，使得整个装置的外露机构非常少，整体结构简洁美观。
在本实施例中，第一连接轴5、第二连接轴7、第三连接轴8和第四连接轴9为相互平行的，能够有效的保证坐部21在两支撑件41之间和相对于伸缩装置1的转动以及后轮机构3在两支撑件41之间和相对于伸缩装置1的转动均更加顺畅和可靠。
需要说明的是，在本实施例中，伸缩装置1采用的是电动推杆，支撑件41的上部的通孔412内设置有控制手柄10，该控制手柄10与电动推杆电连接，使用者能够通过调节该控制手柄10的通断实现控制电动推杆的伸缩运动，从而完成对轮椅的自动折叠，非常方便。扶手411上设置有供手部穿过的通孔412，通孔412的前侧内壁上设有安装位，控制手柄10的第一端部插设于所述安装位内，控制手柄10可关于其第一端部向上转动，当使用者需要对轮椅进行折叠时，只需要将手部穿入通孔412内，握住位于通孔412内部的控制手柄10，使其向上抬起，就能够启动电动推杆，使其伸长或者缩短。但是伸缩装置1的类型选择并不受本实施例的限制，也可以是气动推杆等其他装置，当可按照实际的需要进行选择。
参见图1至图4，本实施例的轮椅还包括脚踏机构11，脚踏机构11可转动地连接于两支撑件41之间，且位于支撑件41的底端，脚踏机构11包括连接于两支撑件41之间的第一支板111以及用于供患者放置脚部的第二支板112，第二支板112的侧边通过第五连接轴114可转动地连接于第一支板111的侧边，第一支板111的两端分别通过第三连接件113与支撑件41固定连接，当对轮椅进行折叠时，将第二支板112向上旋转至立起，由此将脚踏机构11进行折叠，结构简单，操作方便。
综上，本实施例的轮椅的结构设计非常简单，外露机构较少，外观简洁美观，折叠操作非常容易，且较为省力，能够方便老人家或者残疾人进行自主使用。该轮椅在折叠后的体积非常小，收纳和放置方便，且使用者能够通过扶手推动第一轮体和第二轮体转动，对折叠的轮体进行转移和搬运，快捷省力。
