具体实施方式
为了使本发明所要解决的技术问题、技术方案以及有益的技术效果更加清楚明白，以下将结合附图以及多个示例性实施例对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅用于解释本发明，而不是用于限制本发明的保护范围。
首先，根据本发明的第一方面，如图1所示，提供了一种用于车辆、尤其是轨道车辆的电控高度阀1，所述电控高度阀1包括：车身高度变化检测装置11，其用于检测车辆的车身的高度变化并产生表征车身的高度变化的高度变化电信号；控制装置12，其基于高度变化电信号产生相应的阀控制命令；以及阀装置13，其与车辆的二系悬挂系统气体耦合且基于阀控制命令调节二系悬挂系统的气体压力。二系悬挂系统包括气体弹簧。
为了更为清楚以及下面可能的描述的需要，图2示出了图1所示的电控高度阀在组装状态下的立体图。图3示出了图2所示的电控高度阀的正视图。图4示出了图2所示的电控高度阀的俯视图。图5示出了图2所示的电控高度阀的后视图。图6示出了图2所示的电控高度阀的右视图。图7示出了图2所示的电控高度阀的左视图。图8示出了图2所示的电控高度阀的纵向剖视图。
由此可以看出，本发明的电控高度阀1将检测车身的高度变化与对阀装置13的控制分为两个部分，这两个部分可以通过控制程序进行关联，从而可以灵活地调整控制参数而配置出具有不同特性的高度阀。而在现有的机械式高度阀中，车身的高度变化直接变换为阀装置的状态，对应关系唯一，无法进行调整。
在此，如何根据车身的高度变化控制阀装置3，即如何根据车身的高度变化产生相应的阀控制命令可通过实验、模拟等方法事先标定，也可引入其它信号、例如二系悬挂系统的气体压力进行反馈控制。
根据本发明的一个示例性实施例，电控高度阀1还可包括压力传感器 14，其用于检测二系悬挂系统的气体压力。这为反馈控制提供了可能，并且可以用于帮助诊断电控高度阀1的健康状况，具体可参看以下的描述。

根据本发明的一个示例性实施例，第一阀131和/或第二阀132为电磁阀，用于控制二系悬挂系统的充气和放气，也可以和其它阀配合来放大流量，以适应更多的工作应用范围，此时还可能需要其它阀的配合动作。优选地，所述阀装置13还可以包括第一流量放大充气放气控制活塞阀133和/或第二流量放大充气放气控制活塞阀134，以与第一阀131和/或第二阀132协调控制二系悬挂系统的充气和放气过程。根据本发明的一个示例性实施例，第一阀131和第二阀132并排放置，第一流量放大充气放气控制活塞阀133和第二流量放大充气放气控制活塞阀134并排放置。
根据本发明的一个示例性实施例，如图1所示，第一阀131和第二阀132并排布置。
根据本发明的一个示例性实施例，车身高度变化检测装置11可包括驱动杆111和编码器112，其中，驱动杆111与车身连接而能够跟随车身的高度变化进行旋转运动，编码器112能够被驱动杆111驱动以产生高度变化电信号。换言之，编码器112可通过驱动杆111带动旋转体(参考图1)转动来确定车身的高度变化。
根据本发明的一个示例性实施例，编码器112可为光电编码器。
根据本发明的一个示例性实施例，电控高度阀1还可包括壳体15，其中，车身高度变化检测装置11、控制装置12、阀装置13和压力传感器14中的至少一个的至少一部分设置在壳体15内。尤其地，车身高度变化检测装置11的一部分(例如驱动杆111)以及控制装置12、阀装置13和压力 传感器14均设置在壳体15内。
优选地，壳体15在此充当阀体，并可内置一部分气路。
根据本发明的一个示例性实施例，电控高度阀1还可包括顶盖16，所述顶盖16安装于壳体15。在这种情况下，顶盖16与壳体15形成一个相对封闭的容纳空间。
优选地，电控高度阀1的一部分气路也可内置于顶盖16中。
根据本发明的一个示例性实施例，壳体15可设有进气口151和出气口152，所述进气口151处设有进气接头153。进气口151可通过进气接头153连接到气源。
根据本发明的一个示例性实施例，电控高度阀1还可包括设置在顶盖16上的电气接口17。该电气接口17可连接到电源，并可以优选与车辆的控制系统进行通信。
根据本发明的一个示例性实施例，顶盖16可设有用于安置车身高度变化检测装置11的通孔结构161。从而可以将位于壳体15外部的驱动杆111的转动传递到位于壳体15内的编码器112。
根据本发明的一个示例性实施例，顶盖16可通过密封垫18密封地安装于壳体15，即密封垫18设置在顶盖16与壳体15之间。这样，可以将相应的电气部件密封地置于容纳空间中，从而可以对内部的电气部件进行很好的保护。
根据本发明的一个示例性实施例，顶盖16可以通过紧固件19、例如螺钉(图1中示例性地示出了三个螺钉)固定于壳体15。
优选地，壳体15可具有顶部敞口的方形轮廓，如图1所示，进气口151设置在壳体15的第一侧面154处，出气口152设置在壳体15的与第一侧面154相邻的第二侧面155处。优选地，进气口151设置在窄侧面处，而出气口152设置在宽侧面处。
根据本发明的一个示例性实施例，如图1所示，电气接口17可设置在顶盖16的一个侧边162处。
根据本发明的一个示例性实施例，如图1所示，顶盖16在与电气接口17对应的顶部处设有凸台163。这样，可以给设置电气接口17提供较大的区域。
根据本发明的一个示例性实施例，控制装置12可进一步被配置成能够在调整车身高度的过程中至少基于二系悬挂系统的气体压力和高度变化电信号判断阀装置13的工作状态。这是因为正常状态下，阀装置13只要工作，二系悬挂系统的气体压力必然变化，而阀装置13是否启动又与车身的高度变化电信号有关。
根据本发明的一个示例性实施例，控制装置12可进一步被配置成监测阀装置13的动作。这样，可以通过确定阀装置13的动作来判断阀装置13本身、甚至其它部件的状态，例如第一阀131和/或第二阀132是否达到了预期的动作次数。因此，根据本发明的一个示例性实施例，监测阀装置13的动作包括统计阀装置13的动作次数。
如上所述，可通过比较二系悬挂系统的气体压力与高度变化电信号来判断阀装置13的工作状态。
根据本发明的一个示例性实施例，控制装置12可进一步被配置成通过对车身高度变化检测装置11和/或阀装置13和/或压力传感器14的监测来诊断电控高度阀1的健康状况。
根据本发明的一个示例性实施例，健康状况可包括故障和/或剩余使用寿命。
根据本发明的一个示例性实施例，对电控高度阀1的健康状况的诊断还可引入电控高度阀1的历史数据和/或与电控高度阀1同类型的其它电控高度阀的相关数据。这样，可以充分发挥历史数据以及其它相关数据的作用，利用大数据判断分析，从而可大大提高诊断的准确性，赋予电控高度阀1更多的智能性。
可以看出，在此提供了一种高度集成的智能高度阀，其集成地使用了解码器、例如光电解码器来检测和表征轨道车辆的二系悬挂系统的高度变化(即车身的高度变化)，并根据表征高度变化的信号通过内置的控制装置来自动调节车身的二系悬挂系统的高度，同时也可内置压力传感器，通过优化算法可进行自身功能的监控和预期使用寿命的计算。
尤其地，可以将电控高度阀设计成与现有的轨道车辆的高度阀互相兼容，从而无需改变轨道车辆的相应部位的设计。
在保证现有的高度阀对车身高度自动调整功能的同时，还可实现车辆 运行系统在无人运行过程中对高度阀的状态感知，并可对高度阀的使用极限进行预警，避免故障发生，降低维修成本。
根据本发明的第二方面，提供了一种车辆，其中，所述车辆包括所述电控高度阀1和二系悬挂系统，所述电控高度阀1可以用于控制二系悬挂系统。
尽管这里详细描述了本发明的特定实施方式，但它们仅仅是为了解释的目的而给出的，而不应认为它们对本发明的范围构成限制。在不脱离本发明精神和范围的前提下，各种替换、变更和改造可被构想出来。
