其中，图3视出本申请连杆结构中第一连杆2、第二连杆5，以及弹簧7的平衡状态和展开状态示意图。图4视出本申请连杆结构中第一连杆2、第二连杆5，以及弹簧7的平衡状态和回收状态示意图。图4视出本申请连杆结构中第一连杆2、第二连杆5，以及弹簧7的展开状态和回收状态示意图。
如图1-图5所示，本发明实施例优选实施例的一种连杆结构，其包括：安装板1、弹簧7、第一连杆2、设置于所述安装板1的第一座体3、枢接在所述第一座体3上并具有滑动通道的转动套4、以及滑设在所述滑动通道内的第二连杆5，以及设置在所述安装板1上的第二座体6。
所述第一连杆2的第一端通过第一枢轴13与所述第二座体6相枢接，所述第一连杆2的第二端与所述第二连杆5的第一端相铰接；所述弹簧7的第一端通过第二枢轴14枢接在所述第二座体6上，所述弹簧7的第二端通过第三枢轴15与所述第一连杆2或第二连杆5枢接，也即是本申请的弹簧7的第二端枢接在第一连杆2和第二连杆5上均能够实现本申请的方案；所述第一枢轴13、所述第二枢轴14，以及所述第三枢轴15分别平行设置；所述第一枢轴13的轴线与所述第三枢轴的轴线之间的距 离为第一距离；所述第一枢轴13的轴线与所述第二枢轴14的轴线之间的距离为第二距离；所述第一距离与所述弹簧7的自然伸长长度之和大于所述第二距离。
其中，以当弹簧7的第二端通过第三枢轴15与所述第一连杆2枢接为例，进行说明，参见图5，本申请具有展开状态或回收状态，分别能够实现第二连杆5的第二端伸出或回收，本申请的弹簧7的自然伸长长度为弹簧7处于自然状态下的长度，最小伸出长度为弹簧7压缩至最小的长度。本申请在回收状态时，第一连杆2的第二端位于第二座体6远离第一座体3的一侧，并且在所述弹簧7的伸出长度与所述第一距离之和等于所述第二距离时，所述弹簧7处于压缩状态，因此当第一连杆2的第二端需要越过所述第一连杆2的第一端和所述弹簧7的第一端的连接线时，需要提供一个外力作用，在不施加外力作用的情况下，由于压缩弹性结构对第一连杆2施加了一个支撑力，并且该支撑力背向第一座体3，使第一连杆2的第二端始终位于第二座体6远离第一座体3的一侧，也即是第二连杆5的第二端与第一座体3的距离最短，此时本申请处于回收状态。
参见图3和图4，当本申请需要从回收状态切换至展开状态时，通过外力作用拉动第二连杆5使第二连杆5朝远离第二安装座的方向运动(或通过外力作用竖直向下压第二连杆5的第二端)，并且该外力作用需要使第一连杆2的第二端越过所述第一连杆2的第一端和所述弹簧7的第一端的连接线，越过该连接线后由于压缩弹性结构对第一连杆2施加了一个支撑力(该支撑力来源于弹簧7的压缩蓄能)，并且该支撑力朝向第一座体3，该支撑力驱动第一连杆2的第二端朝向第一座体3的方向运动，从而驱动第二连杆5绕转动套4转动并朝远离第一座体3的方向伸出转动套4，也即是第二连杆5的第二端与第一座体3的距离伸长，此时本申请处于展开状态。
参见图3和图4，当本申请需要从展开状态切换至回收状态时，通过外力作用拉动第二连杆5使第二连杆5朝靠近第二安装座的方向运动 (或通过外力作用竖直向上顶置第二连杆5的第二端)，并且该外力作用需要使第一连杆2的第二端越过所述第一连杆2的第一端和所述弹簧7的第一端的连接线，越过该连接线后由于压缩弹性结构对第一连杆2施加了一个支撑力(该支撑力来源于弹簧7的压缩蓄能)，并且该支撑力背向第一座体3，使第一连杆2的第二端始终位于第二座体6远离第一座体3的一侧，也即是第二连杆5的第二端与第一座体3的距离缩短，此时本申请处于回收状态。
又一设计中，参见图5，本申请具有展开状态或回收状态，分别能够实现第二连杆5的第二端伸出或回收，本申请的弹簧7的自然伸长长度为弹簧7处于自然状态下的长度，最小伸出长度为弹簧7压缩至最小的长度。本申请在回收状态时，第一连杆2的第二端位于第二座体6远离第一座体3的一侧，并且在所述弹簧7的伸出长度与所述第一距离之和等于所述第二距离时，所述弹簧7处于压缩状态，因此当第一连杆2的第二端需要越过所述第一连杆2的第一端和所述弹簧7的第一端的连接线时，需要提供一个外力作用，在不施加外力作用的情况下，当弹簧7的第二端通过第三枢轴15与所述第二连杆5枢接时，由于压缩弹性结构对第二连杆5施加了一个支撑力，并且该支撑力背向第一座体3，使第二连杆5的第二端始终位于第二座体6远离第一座体3的一侧，也即是第二连杆5的第二端与第一座体3的距离最短，此时本申请处于回收状态。
当弹簧7的第二端通过第三枢轴15与所述第二连杆5枢接时，当本申请需要从回收状态切换至展开状态时，通过外力作用拉动第二连杆5使第二连杆5朝远离第二安装座的方向运动(或通过外力作用竖直向下压第二连杆5的第二端)，并且该外力作用需要使第一连杆2的第二端越过所述第一连杆2的第一端和所述弹簧7的第一端的连接线，越过该连接线后由于压缩弹性结构对第二连杆5施加了一个支撑力(该支撑力来源于弹簧7的压缩蓄能)，并且该支撑力朝向第一座体3，该支撑力驱动第二连杆5的第一端朝向第一座体3的方向运动，从而驱动第二连杆5绕 转动套4转动并朝远离第一座体3的方向伸出转动套4，也即是第二连杆5的第二端与第一座体3的距离伸长，此时本申请处于展开状态。
参见图3和图4，当本申请需要从展开状态切换至回收状态时，通过外力作用拉动第二连杆5使第二连杆5朝靠近第二安装座的方向运动(或通过外力作用竖直向上顶置第二连杆5的第二端)，并且该外力作用需要使第一连杆2的第二端越过所述第一连杆2的第一端和所述弹簧7的第一端的连接线，越过该连接线后由于压缩弹性结构对第二连杆5施加了一个支撑力(该支撑力来源于弹簧7的压缩蓄能)，并且该支撑力背向第一座体3，使第一连杆2的第二端始终位于第二座体6远离第一座体3的一侧，也即是第二连杆5的第二端与第一座体3的距离缩短，此时本申请处于回收状态。
本申请通过利用弹簧7的压缩蓄能实现对第一连杆2或第二连杆5的支撑，从而使第二连杆5伸出或收缩入限位套，以解决以往电动机构成本高、行程小，以及通用性不高的问题，使本申请的通用性更强、可调整行程更大，使用环境要求更低，同时也降低了产品成本，减少了零件数量，提高了生产效率。
一种实施例中，参见图1，所述弹簧7为压缩气弹簧7，使在压缩时能够储能，从而在第一连杆2的第二端越过所述第一连杆2的第一端和所述弹簧7的第一端的连接线时，能够通过压缩储能实现自动对第一连杆2的驱动。
可以理解的是，压缩气弹簧7的伸出端或缸体端均可以枢接第一连杆2或枢接在所述第二座体6上。
可以理解的是，滑动通道与滑动套的枢接方向相垂直设置。
一种实施例中，所述安装板1为平板，所述第一座体3和第二座体6均连接于所述安装板1的底壁，所述第一连杆2铰接于第二座体6上，并且第二座体6、第一座体3，以及第二连杆5的第二端依次设置。
具体地，参见图5，所述第二座体6包括：设置在所述安装板1上的第一板体61和设置在所述安装板1上的第二板体62；所述第一板体61和 所述第二板体62分别与所述第一枢轴13垂直设置；第一枢轴13的一端设置在所述第一板体61上，第一枢轴13的另一端设置在所述第二板体62上；第一杆体连接在所述第一板体61与所述第二板体62之间的所述第一枢轴13上。
并且。所述弹簧7的数量为两个，分别为第一压缩气弹簧71和第二压缩气弹簧72。第一压缩气弹簧71和第二压缩气弹簧72的设置，能够使本申请的压缩储能更大，并且更加稳定，对第一连杆2的支撑的反应更加迅速，并且第一压缩气弹簧71和第二压缩气弹簧72分别位于第一连杆2的相对两侧能够有效防止第一连杆2的受力不均匀导致变形。
可选地，第一座体3包括：第三板体和第四板体。第三板体和第四板体均与所述安装板1垂直设置的，并且第一板体61、第二板体62、第三板体，以及第四板体呈相平行设置。并且转动套4位于第三板体和第四板体之间，转动套4的相对两侧分别通过转轴枢接在第三板体和第四板体的内侧壁。
在本申请的描述中，弹簧7始终保持压缩状态，使本申请无论处于展开状态或回收状态时，均能够将第一连杆2抵在安装板1的底壁上，以确保本申请在没外力作用时整个结构不易晃动。
可选的，在第一连杆2、第一压缩气弹簧71，以及第二压缩气弹簧72处于同一直线时，本申请处于平衡状态(无外力的作用下，第一连杆2、第一压缩气弹簧71，以及第二压缩气弹簧72始终处于同一直线)，也即是处于所述第一连杆2的第一端和所述弹簧7的第一端的连接线时，缩短至最小距离，也即是第一压缩气弹簧71和第二压缩气弹簧72的压缩储能最大，从而使有更好的支撑力支撑起第一连杆2。
一种实施例中，参见图2，本申请还包括：第一止挡块11和第二止挡块12；所述第一枢轴13的轴线位于所述第一止挡块11和所述第二止挡块12之间；第一止挡块11和所述第二止挡块12均位于第一杆体的转动杆路径上；所述第一止挡块11具有第一止挡面111；所述第一止挡面111可与所述第一连杆2相抵接；所述第二止挡块12具有第二止挡面121； 所述第二止挡面121可与所述第二连杆5相抵接，也即是当本申请处于回收状态时，弹簧7将第一连杆2的侧壁抵接在第一止挡面111上，弹簧7将第一连杆2的侧壁抵接在第二止挡面121上，以确保本申请在没外力作用时整个结构不易晃动。
同时，当弹簧7将第一连杆2的侧壁抵接在第一止挡面111上时，第一连杆2的侧壁与第一止挡面111相适配，也即是第一止挡面111为一与第一连杆2侧壁相适配的凹槽，从而使第一连杆2与第一止挡面111之间的抵接更加稳固。
可选地，在所述第一止挡面111与所述第一连杆2相抵接时，所述弹簧7处于压缩状态，从而将第一连杆2压紧再第一止挡面111上。
同时，当弹簧7将第二连杆5的侧壁抵接在第二止挡面121上时，第一连杆2的侧壁与第二止挡面121相适配，也即是第二止挡面121为一与第一连杆2侧壁相适配的凹槽，从而使第一连杆2与第二止挡面121之间的抵接更加稳固。
可选地，在所述第二止挡面121与所述第一连杆2相抵接时，所述弹簧7处于压缩状态，从而将第一连杆2压紧再第二止挡面121上。
本申请实施例还提供一种踏板10装置，参见图1-图5，其包括：踏板10和上述的连杆结构。所述踏板10与所述第二连杆5的第二端固定连接，通过驱动第二连杆5的第二端的伸出或收缩从而控制踏板10的伸出或收缩。
本申请实施例还提供一种汽车，其包括：汽车本体和如上所述的踏板10装置。所述安装板1设置在所述汽车本体的底盘上。所述第一连杆2、所述第一座体3，以及第二座体6位于所述底盘的下方。那么用户能够通过用脚竖直下压或竖直向上顶置第二连杆5的第二端，从而实现连杆结构在展开状态或回收状态之间切换。连杆结构在回收状态时，踏板10位于底盘的正下方，连杆结构在展开状态时，踏板10伸出底盘的正下方，从而供用户使用。
综上，本发明实施例提供一种连杆结构、踏板10装置，以及汽车， 其解决电动四连杆机构成本高、行程小，以及通用性不高的问题。并且本申请相对四连杆结构更加简单、通用性更强，以及可调整行程更大，使用环境要求更低，同时也降低了产品成本，减少了零件数量，提高了生产效率。当将本申请的踏板10装置安装在汽车底盘时，能够通过用户竖直向上顶置第二连杆5的第二端或竖直向下下压第二连杆5的第二端以实现踏板10的轻松伸出或缩回。
以上所述仅是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明技术原理的前提下，还可以做出若干改进和替换，这些改进和替换也应视为本发明的保护范围。
