具体实施方式
下面结合具体实施例对本发明作更进一步的说明。
一种门系统多点锁闭机构，包括驱动机构，所述驱动机构在门扇关闭末期和门扇打开前期受导轨约束旋转一定角度，实现驱动机构对门系统局部的锁闭和解锁；同时，旋转的驱动机构带动传动机构产生位移，传动机构通过位移驱动侧面锁闭组件进行锁闭和解锁，使门系统侧面具有多点约束。
第一种实施例：
如图1-图2所示，第一种实施例的一种门系统多点锁闭机构，驱动机构1包括驱动电机101，驱动电机101通过传动带与丝杆102一端相连接，丝杆102上套接有丝杆螺母103，丝杆螺母103一端与传动架104一端通过第一轴销105转动连接，传动架104另一端与传动板106一端相铰接，传动板106另一端连接有携门架107，携门架107与门扇6相连。所述传动板106上设有滚轮108，滚轮108与导轨109移动连接，导轨109包括直线段1091、曲线段1092、凹槽段1093，直线段1091、曲线段1092、凹槽段1093依次连接，当滚轮108运动到凹槽段1093末端时，门扇6关闭到位，传动架104转动收回；当滚轮108从凹槽段1093末端开始运动时，经曲线段1092、直线段1091，门扇逐渐打开，传动架104转动张开。
如图3-图4所示，所述传动机构2包括传动轴201，传动轴201上固定有传动叉202、传动叉202与第一轴销105一端相配合，当第一轴销105随丝杆螺母103转动收回时，传动叉202随第一轴销105向下转动；当第一轴销105随丝杆螺母103转动张开时，传动叉202随第一轴销105向上转动，直到传动叉202与第一轴销105相脱离。所述传动轴201与第一转臂203一端相连接，第一转臂203另一端与第一连杆204一端相连接，第一连杆204另一端与第二转臂205一端相连接。所述传动轴201上还设置有安装块206，安装块206上设置有限位柱207，传动叉202向上转动时与限位柱207相接触。
如图5-图6所示，所述侧面锁闭组件3包括锁体301，锁体301内设置有可旋转的锁叉302，锁叉302内设置有扭簧303，在扭簧303作用下，锁叉302初始处于复位状态，锁叉302后端设置有第二滚轮304；锁体302内还设置有转动轴305，转动轴305上安装有内摆臂306， 转动轴305带动内摆臂306旋转，当内摆臂306转动到位后，内摆臂306前端与第二滚轮304接触，所述转动轴305一端通过万向接头与驱动轴307一端相连接，驱动轴307另一端与第二转臂205另一端相连接。
如图7所示，所述解锁机构4包括解锁手柄401，解锁手柄401与传动机构转动连接，用于带动传动机构反向运动，所述传动机构上设置有解锁弹性部件，用于复位反向运动的传动机构。解锁手柄401可以安装在如传动轴，第一传臂，第一连杆等传动机构上任一部件上，只要能带动其中一个部件反向运动，从而实现驱动轴转动带动侧面锁闭组件进行解锁即可。解锁弹性部件402如扭簧套接在传动轴201上，在扭簧作用下，确保释放解锁手柄后处于复位状态。
如图8所示，所述传动叉位置保持机构5包括：安装板501，所述安装板501上移动连接有限位连杆502，限位连杆502上套接有弹性部件503如：压簧；所述传动轴201上设置有转动块504，转动块504自由端与限位连杆502一端转动连接，传动叉202向上转动时，带动转动块504转动，转动块504带动限位连杆502转动，传动叉202由于限位柱207无法继续向上转动，同时伸弹性部件503通过限位连杆502保持转动块504继续向上转动的作用力，确保传动叉202静止不动。传动叉202向下转动时，带动转动块504转动，转动块504带动限位连杆502转动，传动叉202转动点已过传动板106与传动架104铰接最大转动位置，无法继续向下转动，同时弹性部件503通过限位连杆502保持转动块504继续向下转动的作用力，确保传动叉202锁死不动。
实施例1：
当门扇关闭时，电动机驱动丝杆上丝杆螺母向中间移动，滚轮从直线段移动入曲线段，受曲线段约束，丝杆螺母带动传动架一边向中间运动，一边沿着丝杆向下转动，如图9所示，直到第一轴销与传动叉相接触，带动传动叉一起向下转动，传动叉带动传动轴旋转，并带动转动块转动，转动块带动限位连杆转动。如图10所示，当滚轮进入凹槽段，丝杆螺母完成转动，第一轴销与传动叉停止转动，由于传动板与传动架是铰接，传动架与丝杆螺母通过第一轴销铰接，第一轴销与传动叉的位置低于传动板与传动架的铰接点与丝杆中心点的连线，即过了死点，而且，传动叉由第一销轴带动到最终位置，在传动叉位置保持机构作用下让第一轴销及传动叉锁闭在死点之下，这样可以有效阻碍门扇通过传动架传来的向外拉力及向上运动的力，起到对门扇进行锁闭的作用。另外，滚轮停止在凹槽段的末端，滚轮左右两侧受凹槽段的约束，起到了对门扇沿丝杆方向上的锁闭的作用。
如图11所示，门扇关闭时，门扇6侧面的锁柱601与锁叉相接触，带动锁叉旋转，同时 第二滚轮也旋转，直到门扇关闭完成，如图12所示，锁柱与锁叉完成锁闭，第二滚轮旋转到位。传动轴随传动叉旋转依次带动第一转臂、第一连杆、第二转臂旋转，第二转臂带动驱动轴旋转，驱动轴通过万向接头带动转动轴旋转，转动轴带动内摆臂转动并与第二滚轮相接触，至此，完成了锁叉与锁柱的锁闭。另外，多个侧面锁闭组件可以通过万向接头实现串联，对门扇实现多个锁叉点的锁闭。
实施例2：
当门扇打开时，电动机驱动丝杆上丝杆螺母运动，由于受凹槽段约束，丝杆螺母驱动传动架向上转动，并带动第一轴销与传动叉向上转动，实现了对门扇的第一次解锁，由于传动板与传动架是铰接，传动板可以保持不动，如图9所示，直到传动叉停止在限位柱处，第一轴销与传动叉准备脱离，实现了对门扇的第二次解锁。传动叉向上转动过程中，带动传动轴转动，并通过第一转臂等部件解除内摆臂对锁叉后部第二滚轮的约束，完成侧面锁闭组件解锁。同时，传动叉在传动叉位置保持机构作用下保持静止。
如图13所示，第一销轴与传动叉相脱离后，丝杆螺母继续向上转动，在曲线段，传动架一边转动，一边通过传动板和携门架带动门扇向两侧打开，直到滚轮完成曲线段行程，丝杆螺母完成转动，滚轮在直线段时，丝杆螺母进行水平移动，直到门扇完全打开。
如图11所示，当门扇打开时，内摆臂与锁叉后部第二滚轮脱离，门扇6侧面的锁柱601从锁叉302准备退出，锁叉在扭簧的作用下复位。
实施例3：
需要人工对侧门进行解除锁闭时，手动转动解锁手柄，解锁手柄带动传动轴旋转，并依次带动第一转臂、第一连杆、第二转臂旋转，第二转臂带动驱动轴旋转，驱动轴带动转动轴旋转，转动轴带动内摆臂转动，并与第二滚轮相脱离，解除对锁叉的限位。同时传动轴带动传动叉，使传动架向上转动，解除死点锁闭状态，由于，传动轴上同步旋动的传动叉只造成丝杆螺母和传动架的旋转，并未给传动板带来移动，所以并不会影响门扇的移动。当手动解锁结束后，门扇既可以手动向外打开，解锁手柄在扭簧的作用下复位。
第二种实施例：
如图14-图15所示，第二种实施例的一种门系统多点锁闭机构，驱动机构1包括驱动电机101，驱动电机101与丝杆102一端相连接，丝杆102上套接有丝杆螺母103，丝杆螺母103一端连接有第一轴销105，传动架104前端转动卡接在丝杆螺母103上，传动架104后端与传动板106一端相铰接，传动板106另一端连接有携门架107，携门架107与门扇6相连。所述丝杆螺母103另一端上设有滚轮108，滚轮108与导轨109移动连接，导轨109包括直 线段1091、凹槽段1093，直线段1091、凹槽段1093依次连接，当滚轮108运动到凹槽段1093时，丝杆螺母103的滚轮108一端向下旋转，直到滚轮108卡接在凹槽段1093末端；当滚轮108从凹槽段1093末端开始运动时，丝杆螺母103的滚轮108一端向上旋转，直到凹槽段1093顶端后丝杆螺母103停止转动，经直线段1091，丝杆螺母103水平移动。
如图16-图17所示，所述传动机构2包括传动轴201，传动轴201上固定有传动叉202、，在丝杆螺母103进入凹槽段1093前，第一销轴105与传动叉202接触，当第一轴销105随丝杆螺母103从凹槽段1093顶端运动到末端时，传动叉202随第一轴销105向上转动；当第一轴销105随丝杆螺母103从凹槽段1093末端运动到顶端时，传动叉202随第一轴销105向下转动，丝杆螺母103退出凹槽段1093，进入直线段1091后，第一销轴105与传动叉202脱离接触。。所述传动轴201与第一转臂203中部相连接，第一转臂203一端通过万向接头与第一连杆204相连接；传动轴201一端的安装板上设置有限位柱207，第一转臂203向一侧转动时与限位柱207相接触。
如图18所示，所述侧面锁闭组件3包括驱动轴307，驱动轴307一端通过万向接头与第一连杆204相连接，所述驱动轴307上设置有插销308，第一转臂203通过第一连杆204带动驱动轴307上插销308竖直方向上下移动。
所述解锁机构4包括解锁手柄401，所述驱动轴307上设置有解锁手柄401，解锁手柄401带动驱动轴307上插销308竖直方向上下移动。
所述传动叉位置保持机构5包括：安装板501，所述安装板501上移动连接有限位连杆502，限位连杆502上套接有弹性部件503如：压簧；所述限位连杆502与第一转臂203另一端转动连接。传动叉202向上转动时，传动轴201带动第一转臂203转动，第一转臂203带动限位连杆502转动，第一转臂203由于限位柱207的限位，以及丝杆螺母103上滚轮在凹槽段1093的约束对传动叉202限位，使第一转臂203无法继续同向转动，同时弹性部件503通过限位连杆502保持第一转臂203继续同向转动的作用力，确保传动叉202静止不动，同时也确保驱动轴307上插销308向下不动。传动叉202向下转动时，传动轴201带动第一转臂203转动，第一转臂203带动限位连杆502转动，第一转臂203由于限位柱207无法继续同向转动，同时弹性部件503通过限位连杆502保持第一转臂203继续同向转动的作用力，确保传动叉202静止不动，同时也确保驱动轴307上插销308向上不动。
实施例4：
当门扇关闭时，电动机驱动丝杆上丝杆螺母向导轨末端移动，滚轮从直线段移动入凹槽段，丝杆螺母带动传动架、传动板、携门架、门扇移动，门扇在移门导轨的约束下进行关闭。 如图16所示，当滚轮来到凹槽段顶部，第一轴销与传动叉相接触；滚轮在凹槽段约束下开始向下转动，带动传动叉向上转动，传动叉带动传动轴转动，传动轴带动第一转臂转动，直到滚轮转动到凹槽段下末端，滚轮左右两侧受凹槽段的约束，起到了对门扇沿丝杆方向上的锁闭的作用。
另外，转动的第一转臂带动第一连杆竖直方向向下运动，第一连杆带动驱动轴上插销向下运动，由于此时，门扇已关闭，门扇6侧面设置的锁扣603与车体上安装的插销导向板602配合到位，插销经插销导向板插入锁扣内的锁孔，实现了对门扇侧面的锁闭作用。为了更好的实现对门扇侧面的锁闭强度和精准度，第一连杆上串联有多个插销，车体上还安装有连杆导向板，使得第一连杆上下移动更稳定，实现了对门扇侧面的多点锁闭作用。同时，第一转臂另一端带动限位连杆转动，以及丝杆螺母上滚轮在凹槽段的约束对传动叉限位，使第一转臂无法继续同向转动，同时弹性部件通过限位连杆保持第一转臂继续同向转动的作用力，确保传动叉静止不动，同时也确保驱动轴上插销向下不动。
实施例5：
当门扇打开时，电动机驱动丝杆上丝杆螺母运动，由于受凹槽段约束，如图17所示，丝杆螺母上的滚轮向上转动，带动第一轴销与传动叉向下转动，由于滚轮从凹槽段底部来到顶部，实现了对门扇的第一次解锁。同时，传动叉向下转动时，传动叉带动传动轴转动，传动轴带动第一转臂转动，第一转臂带动第一连杆竖直方向向上运动，第一连杆带动插销向上运动，与门扇侧面锁扣、插销导向板脱离，实现了门扇侧面的解锁。丝杆螺母在电动机作用下沿直线段约束水平移动，与传动叉脱离，并带动门扇在移门导轨的约束下打开。
另外，第一转臂另一端带动限位连杆转动，第一转臂由于限位柱无法继续同向转动，同时弹性部件通过限位连杆保持第一转臂继续同向转动的作用力，确保传动叉静止不动，同时也确保驱动轴上插销向上不动。
实施例6：
需要人工对侧门进行解除锁闭时，手动提起解锁手柄，解锁手柄带动传动轴向上移动，第一连杆带动插销向上运动，与门扇侧面锁扣、插销导向板脱离，实现了门扇侧面的解锁，由于第一转臂的旋转，只会带来丝杆螺母旋转，不会带来丝杆螺母水平移动，所以并不会影响门扇的移动。当手动解锁结束后，门扇既可以手动向外打开。
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，在不脱离本发明原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本发明的保护范围。
