Description

用于轨道车辆的车辆门系统以及轨道车辆
本申请要求于2017年9月29日提交中国专利局、申请号为201721269504.9、申请名称为“用于轨道车辆的车辆门系统以及轨道车辆”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及轨道车辆设备，尤其涉及一种用于轨道车辆的车辆门系统以及包括该车辆门系统的轨道车辆。
背景技术
随着轨道交通的快速发展以及运营速度的大幅提升，对于车辆配套设施的安全使用以及结构强度提出了更高的设计标准。
城际列车的运行速度趋于高速化已成为当今必不可挡的趋势，城际高速列车的主要特点为乘客的流量比较大，并且列车停站的时间较短，这就需要通过增大车辆门系统的净开度来进一步提高乘客的通过效率。净开度大的车辆门系统多为双扇门系统，已知的双扇门系统不能很好地满足高速列车行驶时在车辆会车或通过隧道时的强度要求，也往往因气密性不够好而造成乘客生理上的不适感。
此外，轨道车辆的车辆门系统通常包括驱动门扇开关的丝杠。目前，轨道车辆的车辆门系统的锁闭通常采用锁丝杠的方式来实现。这种锁闭方式在轨道车辆的运行速度相对较低的情况下是可行的。然而，城际列车的高速运行(120km/h至160km/h)会导致列车承受的动态载荷增加，尤其是在列车会车或者通过隧道的情况下，列车承受的动态载荷会增加得尤为明显。在这种情况下，较大的动态载荷会通过列车车门传递给用于锁闭车门的丝杠螺母副，进而导致丝杠螺母副承受的载荷也较大，这可能导致丝杠螺母副失效，从而导致轨道车辆运行的可靠性较差。
综上，如何提高轨道车辆的车辆门系统的结构强度及对外部载荷的承受能力以及车辆门系统的密封效果，从而进一步提高轨道车辆运行的可靠性和舒适性，成为目前亟需解决的问题。
发明内容
本申请提供一种用于轨道车辆的车辆门系统以及包括该车辆门系统的轨道车辆，以解决上述问题。
为此，本申请实施方式的第一方面提供一种用于轨道车辆的车辆门系统，所述车辆门系统包括两个门扇，所述车辆门系统还包括多个增强结构以提高车辆门系统对载荷的承受能力，所述多个增强结构包括第一增强结构，其中：
所述第一增强结构包括分别设置于每个门扇上或者每个门扇的门携架结构上的抵接件以及设置于车体上的楔形构件，所述楔形构件具有楔形抵接面，所述抵接件可在门扇打开和闭合的过程中，沿所述楔形抵接面来回移动并在门扇关闭时与所述楔形构件抵接。
根据本申请的实施方式，门扇在从打开至闭合的过程中，每个门扇上或每个门扇的门携架结构上的抵接件会沿楔形构件的楔形抵接面朝向车厢内部移动，最终到达闭合位置并在此位置与楔形构件抵接。门扇处于最终的闭合位置时，门扇受到的载荷(包括外部载荷以及密封胶条对门扇施加的作用力)可以通过抵接件传递至楔形构件，也就是说，门扇受到的载荷可以通过第一增强结构传递至车体，车体分担了大部分的载荷，从而可以大大降低车辆门系统所承载的载荷，进而提高车辆门系统的结构强度。
此外，门扇处于最终的闭合位置时，由于抵接件抵接于楔形构件，抵接件将对楔形构件施加作用力，反过来，楔形构件也会对抵接件施加反作用力，该反作用力通过抵接件传递至位于门扇周边的密封胶条，从而可以将门扇上的密封胶条压紧至门框，有利于提高轨道车辆的密封性能。
上述实施方式在轨道车辆的运行速度较高、轨道车辆会车或者轨道车辆通过隧道的情况下，对车辆门系统的结构强度及对外部载荷的承受能力的提 高效果尤为明显。
其中，抵接件的具体结构形式不限，只要其可以实现与楔形构件的楔形抵接面相抵接的功能即可。具体地，在申请的实施方式中，抵接件可以是销轴的形式。
此外，可以理解的是，上述提到的楔形构件的楔形抵接面指的是具有一定倾斜角度的平面，在本申请的一个优选的实施方式中，楔形抵接面的倾斜角度可以为45°±5°，具体应用时可以根据门扇的结构以及运行情况确定楔形抵接面的合适的倾斜角度。通常情况下，当楔形倾斜面的倾斜角度为45°时，门扇受到的作用力较为均匀，十分有利于延长车辆门系统的使用寿命，因此，可以认为45°的倾斜角度为楔形抵接面的一个较佳的倾斜角度。
需要说明的是，在本文中提到的楔形构件指的是具有楔形抵接面的结构件，本文并不限定其外部轮廓为严格的楔形形状。
根据本申请的一个方面，所述门携架结构设置在所述门扇的顶部上方，所述楔形构件设置于车辆门系统驱动机构的中间吊座上，所述中间吊座与车体固定连接，所述抵接件为设置于每个门扇的门携架结构上的第一销轴，所述楔形构件具有两个楔形抵接面，每个所述第一销轴可沿着靠近其的楔形抵接面来回移动。
根据本申请的另一方面，所述车辆门系统还包括固定在车体上的门框，所述第一增强结构的抵接件为设置于两个门扇彼此相对的底部角部处的第二销轴，所述第一增强结构的楔形构件设置于所述门框的横向底边，所述楔形构件上设置有两个分别具有楔形抵接面的导向槽，每个所述第二销轴可沿着靠近其的导向槽来回移动。
需要说明的是，前述门框的横向底边是指车辆门系统处于在车体上的安装状态时，固定于车体的门框与地面大体平行并且靠近地面的侧边。相应地，在本申请中，纵向是指当门扇处于在车体上的安装状态时与地面大体垂直的方向。
为了使抵接件在沿楔形构件的楔形抵接面移动的过程中，门扇可实现其 打开和闭合的操作，优选地，所述楔形构件在朝向车厢内部的方向上呈收敛形状。
根据本申请的一个具体实施方式，所述楔形构件包括贯穿其厚度方向的安装孔，所述楔形构件通过安装于所述安装孔内的固定件与所述车辆门系统的驱动中间吊座固定连接。
其中，楔形构件与驱动中间吊座固定连接的具体方式不限，例如可以通过螺纹连接的方式，由于这些连接方式为本领域技术人员所公知，故此处不再赘述。
为了使抵接件在沿楔形构件的楔形抵接面移动的过程中，门扇可实现其打开和闭合的操作，优选地，设置于所述楔形构件上的两个所述两个导向槽在朝向车厢内部的方向上呈收敛形状。
根据本申请的另一方面，所述多个增强结构还包括锁闭装置，所述锁闭装置包括安装板、与所述安装板连接的锁钩构件和限位构件，第一复位构件和第二复位构件，以及设置于门携架或门扇上的与所述锁钩构件配合的锁销，其中：所述锁钩构件通过第一固定轴与所述安装板连接，且所述锁钩构件与所述第一固定轴铰接，所述锁钩构件具有可围绕所述第一固定轴旋转的钩状端部，以及沿所述第一固定轴的轴向伸出的凸出部；所述限位构件通过第二固定轴与所述安装板连接，且所述限位构件与所述第二固定轴铰接，所述限位构件包括限位部，所述限位部可与所述锁钩构件的凸出部相互作用以限制所述锁钩构件的旋转；所述第一复位构件用于在解除限位时使所述锁钩构件从解锁位置运动至锁闭位置；所述第二复位构件用于在解锁时使所述限位构件从锁闭位置运动至解锁位置。
根据本申请的另一方面，所述多个增强结构还包括分别设置于每个门扇远离另一个门扇的纵向侧边的支撑轮结构、压力装置、隔离锁结构以及固定锁钩结构。
本申请的第二方面提供了一种轨道车辆，包括根据上述任一实施方式的车辆门系统。
具有上述车辆门系统的轨道车辆的结构强度和对外部载荷的承受能力相对较高，因而其运行可靠性也较高。

具体实施方式
本申请实施例提供的用于轨道车辆的车辆门系统在从打开至闭合的过程中，每个门扇上或每个门扇的门携架结构上的抵接件会沿楔形构件的楔形抵接面朝向车厢内部移动，最终到达闭合位置并在此位置与楔形构件抵接。门扇处于最终的闭合位置时，门扇受到的载荷(包括外部载荷以及密封胶条对门扇施加的作用力)可以通过抵接件传递至楔形构件，也就是说，门扇受到的载荷可以通过第一增强结构传递至车体，从而可以提高车辆门系统对载荷的承受能力。
为更清楚地理解本申请实施方式，下面以矩形的门扇为例并参照附图以及不同的实施例进行详细说明。
如图1至图2以及图5所示，本申请实施方式提供的用于轨道车辆的车辆门系统，包括两个门扇，车辆门系统还包括多个增强结构以提高车辆门系统对载荷的承受能力，多个增强结构包括第一增强结构30a，其中：
第一增强结构30a包括分别设置于每个门扇上或者每个门扇的门携架结构上的抵接件以及设置于车体上的楔形构件31，楔形构件31具有楔形抵接面310，抵接件可在门扇打开和闭合的过程中，沿楔形抵接面310来回移动并在门扇关闭时与楔形构件31抵接。
在上述实施方式中，车辆门系统优选为双扇的塞拉门系统。因此，可以 理解的是，门扇在打开的最初阶段中，位于门扇上或门携架结构上的抵接件沿着楔形构件的楔形抵接面以发散的方式朝向车厢外部运动，直至抵接件脱离楔形构件的楔形抵接面后，两个门扇向相反的方向移动以完成门扇的打开操作；相应地，门扇在关闭的最后阶段中，位于门扇上或门携架结构上的抵接件沿着楔形构件的楔形抵接面以收敛的方式朝向车厢内部运动，直至抵接件到达最终闭合位置后，门扇处于最终的可靠的闭合状态。
根据本申请的实施方式，门扇处于最终的闭合位置时，门扇受到的载荷(包括外部载荷以及密封胶条对门扇施加的作用力)可以通过抵接件传递至楔形构件，也就是说，门扇受到的载荷可以通过第一增强结构传递至车体，车体分担了大部分的载荷，从而可以大大降低车辆门系统所承载的载荷，进而提高车辆门系统的结构强度及对外部载荷的承受能力。
此外，门扇处于最终的闭合位置时，由于抵接件抵接于楔形构件，抵接件将对楔形构件施加作用力，反过来，楔形构件也会对抵接件施加反作用力，该反作用力通过抵接件传递至位于门扇周边的密封胶条，从而可以将门扇上的密封胶条压紧至门框，有利于提高轨道车辆的密封性能。
在轨道车辆的运行速度较高、轨道车辆会车或者轨道车辆通过隧道的情况下，轨道车辆的车辆门系统受到的外部载荷相对较大，因而在上述情况下，本申请车辆门系统对外部载荷承受能力的提高尤其会为车辆运行的稳定性和舒适性带来明显的效果。
请参考图1至图4所示，在本申请的第一实施方式中，门携架结构设置在门扇的顶部上方，每个门扇均设置有一个门携架结构，楔形构件31设置于车辆门系统驱动机构的中间吊座上，中间吊座与车体固定连接，抵接件为设置于每个门扇的门携架结构上的第一销轴20，楔形构件31具有两个楔形抵接面310，每个第一销轴20可沿着靠近其的楔形抵接面310来回移动。
在该实施方式中，楔形构件31为对称结构，楔形构件31的靠近两个门扇的外端面分别为楔形抵接面310。门扇在打开的最初阶段中，位于每个门携架结构上的第一销轴20沿着楔形构件31的楔形抵接面310以发散的方式朝 向车厢外部运动，直至第一销轴20脱离楔形构件31的楔形抵接面310后，两个门扇向相反的方向移动以完成门扇的打开操作；相应地，门扇在关闭的最后阶段中，位于每个门携架结构上的第一销轴20沿着楔形构件31的楔形抵接面310以收敛的方式朝向车厢内部运动，直至第一销轴20到达最终闭合位置。
可以理解的是，为了使第一销轴20在沿楔形构件31的楔形抵接面310移动的过程中，门扇可实现其打开和闭合的操作，可以优选地，楔形构件31在朝向车厢内部的方向上呈收敛形状，即楔形构件31的两个楔形抵接面310在朝向车厢内部的方向上呈收敛形状。
请参考图5至图8所示，在本申请的第二实施方式中，与上述实施方式不同的是，车辆门系统还包括固定在车体上的门框40，第一增强结构的抵接件为设置于两个门扇彼此相对的底部角部处的第二销轴30，第一增强结构的楔形构件31设置于门框40的横向底边，楔形构件31上设置有两个分别具有楔形抵接面310的导向槽311，每个第二销轴30可沿着靠近其的导向槽311来回移动。
在该实施方式中，楔形构件31也为对称结构，与上述实施方式不同之处在于，该实施方式中的楔形构件的楔形抵接面310并不是楔形构件31的外端面，而是楔形构件31中设置的导向槽311的槽壁。在这种情况下，门扇在打开的最初阶段中，位于两个门扇彼此相对的底部角部处的第二销轴30沿着导向槽311以发散的方式朝向车厢外部运动，直至第二销轴30运动离开楔形构件31的导向槽311；相应地，门扇在关闭的最后阶段中，位于两个门扇彼此相对的底部角部处的第二销轴30沿着导向槽311以收敛的方式朝向车厢内部运动，直至第二销轴30到达最终闭合位置。
可以理解的是，为了使第二销轴30在沿楔形构件31的楔形抵接面310移动的过程中，门扇可实现其打开和闭合的操作，可以优选地，设置于楔形构件31上的两个导向槽311在朝向车厢内部的方向上呈收敛形状。
请参考图9所示，在本申请的第三实施方式中，与上述实施方式不同的 是，多个增强机构还包括锁闭装置30b，锁闭装置30b包括安装板100、与安装板100连接的锁钩构件21和限位构件22、第一复位构件和第二复位构件，以及设置在门携架或门扇上的与锁钩构件21配合的锁销，其中：
锁钩构件21通过第一固定轴11与安装板100连接，且锁钩构件21与第一固定轴11铰接，锁钩构件21具有可围绕第一固定轴11旋转的钩状端部210，以及沿第一固定轴11的轴向伸出的凸出部211；
限位构件22通过第二固定轴12与安装板100连接，且限位构件22与第二固定轴12铰接，限位构件22包括限位部221，限位部221可与锁钩构件21的凸出部211相互作用以限制锁钩构件21的旋转；
第一复位构件用于在解除限位时使锁钩构件从解锁位置运动至锁闭位置；
第二复位构件用于在解锁时使限位构件从锁闭位置运动至解锁位置。
其中，安装板100作为锁钩构件21和限位构件22的一个安装载体，其可以设置在车辆门系统驱动机构的中间吊座上。
本实施方式提供的锁闭装置可通过锁销与锁钩构件的配合实现对车辆门系统的锁闭，以及通过锁销与锁钩构件的解除配合实现对车辆门系统的解锁。当采用当前实施方式的车辆门系统处于关闭状态时，车辆门系统受到的载荷(包括外部载荷以及密封胶条对门扇的作用力)可以通过锁销传递至锁钩构件并进而传递至车体。因此，锁闭装置承担的载荷较小，因而可以通过该锁闭装置对车辆门系统实现较为可靠的锁闭和解锁；此外，由于车辆门系统受到的载荷可以通过该锁闭装置传递至车体，因而车辆门系统承担的载荷也可以大大减小，从而可以进一步提高轨道车辆的车辆门系统的结构强度。
请参考图10所示，在本申请的第四实施方式中，与前述实施方式不同的是，多个增强结构还包括分别设置于每个门扇远离另一个门扇的纵向侧边的支撑轮结构30c、压力装置30d、隔离锁结构30e以及固定锁钩结构30f。
在当前的实施方式中，轨道车辆的车辆门系统共具有11个增强结构，分别为：设置于两个门扇彼此相对的顶部角部的第一增强结构30a和锁闭装置30b、设置于两个门扇彼此相对的底部角部的第一增强结构30a、以及分别设 置于每个门扇上的支撑轮结构30c、压力装置30d、隔离锁结构30e以及固定锁钩结构30f。在上述11个增强结构的作用下，车辆门系统的结构强度及对外部载荷的承受能力得到相当大的提高。当轨道车辆包括该车辆门系统时，轨道车辆运行的可靠性和舒适性也可以得到较大地提高。
以上参照附图对本申请的具体实现方式进行了详细说明，显然，本领域的技术人员可以对本申请进行各种改动和变型而不脱离本申请的精神和范围。这样，倘若本申请的这些修改和变型属于本申请权利要求及其等同技术的范围之内，则本申请也意图包含这些改动和变型在内。
