如图1至图15所示的一种双开塞拉门系统，包括固定架40、设置在固定架40上的塞拉轨道41、横梁11以及安装在横梁11上用于驱动一侧门往复移动的驱动机构，与驱动机构配合的用于牵引另一侧门往复移动的联动机构；驱动机构连接主动套筒组件6，主动套筒组件6通过联动机构牵引从动套筒组件61，联动机构驱动带动主动套筒组件6的门48与从动套筒组件61的门48相向或者相背运动，主动套筒组件6与从动套筒组件61分别通过携门架连接两侧门48；从动套筒组件61上还设置有与塞拉轨道41相配合的滚轮；在横梁两端分别安装挂架49，挂架49之间平行装有两根长导柱50，主动套筒组件6与从动套筒组件61分别套装在不同的长导柱50上，并可在各对应的长导柱50上往复运动，各个长导柱50两端穿过挂架49，并在端部安装滚动部件，滚动部件为轴承等具有滚动功能的装置或零部件，在固定架40上设置一组安装支架43，滚动部件与设置在安装支架43内侧的滑道相配合。安装支架43之间还可以设置一根能够轴向转动的同步杆47，同步杆47两端固定连接联动臂64，各个联动臂64通过连杆与挂架49活动连接。如图15所示，联动机构包括分别安装在各个挂架49上的滚轮及绕在滚轮上的牵引部件63，牵引部件63在两个滚轮之间形成闭环，该闭环牵引部件63的一边与主动套筒组件6连接，另一边与从动套筒组件61连接，而牵引部件63可以为同步带、钢丝绳、传动链等，使用传动链时滚轮可更换为齿轮。
如图7至图14所示，驱动机构包括固定于横梁11上的电机1、导向锁块51以及限 位机构4，电机1与控制器连接；电机1的轴连接丝杆2，在丝杆2上成套配置有螺母组件3；螺母组件3包括螺母31以及与螺母31刚性连接的随动部件7，螺母31与丝杆2构成螺旋运动副，在螺母31外侧安装有传动架9，传动架9与螺母31之间可相对运动；传动架9与螺母31之间设置有扭簧10，扭簧10以传动架9为支撑向随动部件7施加压力，传动架9连接主动套筒组件6，丝杆2正向转动过程中，带动螺母31与随动部件7同时运动，当运动到随动部件7与导向锁块51接触后，随动部件7在导向锁块51上表面的导向下运动至限位机构4并被该限位机构4阻挡，随动部件7随丝杆2转动进入导向锁块51的侧面与限位机构4之间的空间而被锁定；丝杆2反向转动时，随动部件7随丝杆2反向转动至脱离导向锁块51的限制而解除锁定，然后沿丝杆2轴向运动。导向锁块51具有一面向限位机构4的侧面，该侧面与限位机构4之间形成能够落入随动部件7的空间。侧面为能够限制随动部件7弹出的斜面，侧面与竖直面之间的夹角为0-10°，在此角度范围内，导向锁块51既能对随动部件7施加作用力，又不会因角度过大而导致随动部件7被锁死的问题，该角度优选为3°。而在传动架9中还有限定螺母31随丝杆2转动角度范围的机构，该机构为一个空间，螺母31上的随动部件7在该空间中随螺母31上下运动，该空间的上端与下端限定了随动部件7的转动范围，进而限定了螺母31随丝杆2运动时的转动范围。
如图7所示，作为第一种实施方式，导向锁块51具有一引导随动部件7向限位机构4移动的光滑的上表面，在随动部件7运动过程中，当其不与导向锁块51上表面接触时，处于自由状态，即位于上述限定随动部件7转动的空间的下端，设置在螺母31与传动架9之间的扭簧10可设置为处于放松状态或者较小的压缩状态，不向螺母31施加扭转力，或者向螺母31施加较小的扭转力，可使螺母31在带动随动部件7运行中，更加平稳。当随动部件7通过导向锁块51上表面时，扭簧10被压缩，向螺母31施加扭力，由此，保证了随动部件7能够在接触到限位板13后，通过丝杆2转动带动螺母31以及扭簧10施加的扭转力，可顺利地进入限位板13与导向锁块51之间的空间。
如图8所示，作为第二种实施方式，横梁11上还固定安装有用于随动部件7移动的滑轨5，该滑轨5与导向锁块51相接并与导向锁块51的上表面平滑过渡，具体为，导向锁块51设置在滑轨5靠近限位部件的一端，并具有水平的上表面，与滑轨5的上表面相接成为一个整体水平表面。设置滑轨5后，随动部件7即与滑轨5上表面接触并可在该上表面上往复运动，在这种设置方式下，随动部件7位于上述限定随动部件7转动的空间的上端与下端之间，不与上端或下端接触，此时螺母31与传动架9之间的扭簧10处于压缩状态，当随动部件7运动到与限位板13接触后，丝杆2转动带动螺母31转动的力以及扭簧10对螺母31施加的扭转力，保证了随动部件7能够顺利进入限位板 13与导向锁块51之间的空间。设置滑轨5，使随动部件7在滑轨5的限制下运动，能够进一步增加螺母组件3运动的平稳性。
如图9至图12所示，传动架9具有与主动套筒组件6连接的安装部91，安装部91向上延伸形成由四根立柱92构成的螺母安装部，螺母31安装在四根立柱92构成的空间内，在其中面向横梁11一侧的两根立柱92顶端安装有限定螺母31随丝杆2转动角度范围的限位销12，因此，限位销12与横梁11侧的两根立柱92的底部与限位销12之间形成了螺母31随丝杆2转动时的转动空间，限位销12即为上述的上端，而两根立柱92之间空间的底部则为下端。螺母31的外径大于两侧立柱92之间的距离，因此螺母31被限制在两侧立柱92之间的空间内，在螺母31沿丝杆2轴向运动时，通过对不同侧的立柱92施加推力，带动传动架9随螺母31一起运动，螺母31由内圈和外圈构成，内圈与丝杆2螺纹配合，外圈套在内圈上并通过防滑齿相互配合，外圈面向横梁11一侧向外延伸有随动部件7的安装座，安装座有一螺孔，随动部件7有一螺杆，螺杆旋接在螺孔内，使随动部件7和螺母31固定连接。随动部件7可以采用滚轮，也可是其他类型表面光滑运行阻力小的部件，如表面光滑的滑动块等。采用滚轮与导向锁块51搭配，在通过导向锁块51表面时能最大限度减小螺母组件3的运行阻力，提升系统的使用平稳性。螺母31的外圈两侧分别位于对应的相邻立柱92之间，丝杆2通过螺母31外圈驱动传动架9沿丝杆2轴向移动。螺母组件3中还包含向螺母31施加扭转力扭簧10，扭簧一端搭靠在传动架9上，另一端搭靠在螺母31上，扭簧采用内径大于丝杆2直径的型号，套在丝杆2外部，螺母31外圈有向外延伸有挡块32，扭簧一端搭靠在该挡块32上。
如图13所示，限位机构4包括一个安装在横梁11上的限位板13，该限位板13具有面向导向锁块51的侧面，该侧面与导向锁块51的侧面构成能够落入随动部件7的空间，限位板13通过销轴14可旋转地安装在横梁11上，该限位板13面向导向锁块51一侧具有弯折的立板26，该立板26的角度根据实际应用时配做，具体为，在随动部件7不与立板26接触时，该弯折立板26的上半段为竖直，下半段向导向锁块51的方向弯折，而随动部件7与立板26接触后，驱动限位板13转动，当转动停止后，下半段变为竖直方向，上半段向导向锁块51的方向弯折，立板26的弯折度，根据限位板13的转动角度而设定，如限位板13的转动角度为α，那么立板26的上半段与下半段之间所夹钝角的角度为180°-α；限位板13和销轴14之间还设置有复位弹簧，复位弹簧可以为扭簧，扭簧套在销轴14上，其一端固定在限位板13上，另一端固定在横梁11上，限位板13在旋转动作中能够通过其边缘触发信号开关15，限位板13上开有腰孔27，横梁11上安装有限位销19，限位销19伸入腰孔27内限制限位板13旋转角度。
如图5、图6所示，固定架40上还设置有导向限位杆42，其一端与固定架40固定连接，另一端为自由端；限位板13可旋转地安装在横梁11上，当两侧门48在驱动机构和联动机构的带动下关闭时，限位板13旋转直至阻挡导向限位杆42的自由端，限制被牵引的一侧门回移；当两侧门48在驱动机构和联动机构的带动下打开时，限位板13反转而解除对导向限位杆42自由端的阻挡，使被牵引的一侧门往回移动，限位板13反转而解除对导向限位杆42自由端的阻挡后，导向限位杆42抵近限位板13边缘，限制限位板13转动。
如图13、图14所示，限位机构4还包括一个手动机构，该手动机构包括一个安装在横梁11上的固定支架20和一个安装在销轴14上的活动支架17，两个支架之间安装有复位弹簧，复位弹簧可以为扭簧，扭簧套在销轴14，其一端固定在固定支架20上，另一端与活动支架17固定连接，活动支架17在旋转过程中能够将随动部件7从导向锁块51与限位机构4之间的空间中拨出，具体为，可在活动支架17下部设置一个弯折的拨动块21，拨动块21从随动部件7下方将其从导向锁块51与限位机构4之间的空间中拨出，活动支架17可通过手动拉绳8驱动绕销轴14转动，手动拉绳8与解锁开关连接，解锁开关可以为一个手动旋钮，旋转时能够拉动手动拉绳8。在实际应用中，其实际安装在诸如地铁内壁等能够使人容易接触到的位置上。当旋动解锁开关带动活动支架17以销轴14为转动中心转动时，拨动块21推动随动部件7向上运动。活动支架17与限位板13安装在同一个销轴14上，二者相互之间不会干涉，并且集成度高，能够节省安装空间。
本发明的一种双开塞拉门系统，可分为以下运动过程及状态：
1、电动锁门：控制器向电机1发出信号，使电机1驱动丝杆2转动，丝杆2通过螺母组件3驱动随动部件7沿丝杆2轴向向限位机构4运动，当随动部件7接触到导向锁块51时，在导向锁块51上表面的导向下运动至限位板13并被该限位板13阻挡，随动部件7随丝杆2转动进入导向锁块51的侧面与限位板13之间的空间而被锁定，在此过程中，限位板13转动，触发设置在其下方的信号开关15，信号开关15向控制器发出到位信号后，控制器控制电机1停转，完成锁门。此时，限位板13阻挡在导向限位杆42自由端前部，当联动机构失效时，由于主动套筒组件6的门已被导向锁块锁定，因此不会轻易被打开。而如果没有导向限位杆42，从动套筒组件61一侧的门则能够被手动打开，并带动整个横梁进行塞拉动作。设置了导向限位杆42，塞拉动作即被阻挡，因此即使手动拉动从动套筒组件61一侧的门，也不能够打开。
2、电动开门：控制器向电机1发送信号，使电机1带动丝杆2反向转动，随动部件7随丝杆2反向转动至脱离导向锁块51的限制而解除锁定，并于限位板13脱离，限 位板13在扭簧的作用下回位，解除对导向限位杆42的阻挡，触发信号开关15向控制器发出解锁信号，然后限位部件沿丝杆2轴向运动。当随动部件7运动到丝杆2另一端时，电机1停转，完成开门，此时导向限位杆42处于限位板13的上方并能够限制限位板13反向回转，避免误触信号开关。
3、手动锁门：手动驱动主动套筒组件6，使螺母组件3在丝杆2轴向向限位机构4运动，此时丝杆2为被动转动。当随动部件7接触到导向锁块51时，在导向锁块51上表面的导向下运动至限位板13并被该限位板13阻挡，随动部件7随丝杆2转动进入导向锁块51的侧面与限位板13之间的空间而被锁定，在此过程中，限位板13转动，触发设置在其下方的信号开关15，信号开关15向控制器发出到位信号后，控制器控制电机1停转，完成锁门。
4、手动开门：两侧门锁定状态时，通过转动解锁开关，使得手动拉绳8拉动活动支架17绕销轴14做顺时针方向转动，活动支架17的拨动块21从下部将随动部件7拨动，使随动部件7离开锁定位置，同时扭簧驱动限位板13绕销轴14顺时针转动，并触发信号开关15，松开解锁开关后，活动支架17在复位弹簧的驱动下旋转到起始位置，然后手动驱动主动套筒组件6，使螺母组件3在丝杆2轴向向远离限位机构4的方向运动，实现手动开门。
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。
