下面参考图1-图3描述根据本申请实施例的车辆1000的接地装置100及车辆1000的导电系统500。
如图1和图2所示，根据本申请实施例的车辆1000的接地装置100，接地装置100包括：接地刀10和接地槽20。
具体而言，如图1和图2所示，接地刀10包括固定部110和受流部120，固定部110和受流部120均为导电件。固定部110与车辆1000的底部电连接，受流部120与固定部110的自由端连接，也就是说，固定部110的上端与车辆1000的底部相连，固定部110的下端与受流部120连接。由此，当车辆1000存在静电或漏电时，车身上的电流可以直接传递至接地刀10，以便于将车身的电流接地。需要进行说明的是，本申请中的“电连接”指的是两个连接部件之间可以有电流通过，而不是指两个连接部件之间始终有电流通过，例如上述的固定部110和车辆1000的底部电连接指的是电流可以流经固定部110和车辆1000。
接地槽20接地，接地槽20具有槽体210，当接地刀10伸入槽体210时，接地刀10与接地槽20电连接以将车辆1000接地。由此，可以将车辆1000的静电或漏电通过接地刀10和接地槽20的配合进行接地，结构简单，运行稳定、可靠。
根据本申请实施例的车辆1000的接地装置100，通过设置接地刀10和接地槽20，并将接地刀10设置为导电件，车辆1000的静电或漏电电流可以直接经过接地刀10和接地槽20进行接地，结构简单，运行稳定、可靠，提高了车辆1000的安全性能。
根据本申请的一些实施例，接地刀10可以为金属件。由此，便于接地刀10的加工制造。而且，金属件具有良好的结构强度和良好的导电性能。接地刀10采用金属件，可以提高接地刀10的导电性能，延长接地刀10的使用寿命。例如，接地刀10可以是钢制件或其他金属制件。
在本申请的一些实施例中，如图1和图2所示，受流部120可以沿平行于车辆1000 的长度方向延伸。可以理解的是，当车辆1000运行时，接地刀10随着车辆1000一起运动。通过将受流部120设置为沿平行于车辆1000的长度方向延伸，当车辆1000行驶至站台或接地位置时，接地刀10可以随着车辆1000的运动方便地伸入到接地槽20内。由此，提高了车辆1000接地装置100运行的便利性和可靠性。可以理解的是，当车辆1000的行驶方向与车辆1000的长度方向平行时，受流部120即沿车辆1000的行驶方向延伸。
根据本申请的一些实施例，如图1所示，沿车辆1000的行驶方向，受流部120的两端的厚度可以小于受流部120的中间部分的厚度。也就是说，沿车辆1000的长度方向，受流部120可以设置为两端薄、中间厚的形状。由此，当接地刀10与接地槽20接触时，受流部120的两端可以起到导向的作用。由此，便于接地刀10伸入至接地槽20内。
根据本申请的一些实施例，如图3所示，接地槽20包括：罩体220和两片导电片230。罩体220为绝缘件。由此，通过设置罩体220，罩体220可以对导电片230起到遮挡保护的作用，有效避免了人员误触导电片230而存在触电等安全隐患。
两片导电片230通过连接件240与罩体220连接，两片导电片230间隔设置以构造出槽体210。如图3所示，两片导电片230被构造为板状，两片导电片230沿车辆1000的行驶方向延伸，且两片导电片230间隔设置构造出槽体210。由此，便于接地刀10与接地槽20之间的配合。
具体地，如图3所示，罩体220包括两个间隔设置的子部分2201，两个子部分2201沿车辆1000的宽度方向间隔设置，两片导电片230分别通过连接件240与两个子部分2201的朝向彼此的表面相连。即两片导电片230位于两个子部分2201限定的空间内，例如如图3所示，右侧的导电片230位于右侧的子部分2201的左侧壁上，左侧的导电片230位于左侧的子部分2201的右侧壁上，从而使得罩体220可以对导电片230起到遮挡保护的作用。
如图3所示，在本申请的一些实施例中，连接件240包括：外筒241、内筒242和弹性件243。其中，外筒241与罩体220连接。由此，通过设置外筒241，便于连接件240与罩体220之间的装配连接。例如，外筒241与罩体220之间可以螺纹装配。内筒242的第一端可移动地内套于外筒241，内筒242的第二端通过铰接组件244与导电片230可转动地连接。由此，通过内筒242与外筒241之间的相对滑动，可以带动对应的导电片230的移动，而且内筒242通过铰接组件244与导电片230可转动地连接，可以使导电片230相对于罩体220转动，以缓冲吸收接地刀10对接地槽20的冲击。弹 性件243外套于内筒242，弹性件243的一端定位在铰接组件244上，弹性件243的另一端定位在外筒241。由此，在弹性件243的弹性恢复力的作用下，可以驱使内筒242恢复至原始位置。而且，当接地刀10伸入接地槽20内时，弹性件243可以缓冲吸收接地刀10对导电片230的冲击。
在本申请的一些实施例中，如图3所示，铰接组件244可以通过销245与内筒242的第二端可转动地连接。由此，便于内筒242与铰接组件244的连接，而且可以使对应的导电片230以销为转轴发生小范围的转动，从而可以缓冲吸收接地刀10对接地槽20产生的冲击，进而可以减轻噪声并延长接地槽20的使用寿命。
在本申请的一些实施例中，如图3所示，连接件240可以为弹性连接件240。可以理解的是，当接地刀10随着车辆1000的运动伸入对应的接地槽20内时，接地刀10与接地槽20撞击。接地刀10挤压驱使两片导电片230朝向远离彼此的方向移动。通过设置弹性连接件240，当接地刀10挤压驱使两片导电片230朝向远离彼此的方向移动时，弹性连接件240可以起到缓冲的作用，从而可以降低充电装置的噪声。而且，在弹性恢复力的作用下，弹性连接件240驱使至两片导电片230朝向靠近彼此的方向移动。由此，可以提高接地刀10与接地槽20配合的稳定性和可靠性。当接地刀10与接地槽20脱离时，在弹性连接件240的弹性恢复力的作用下，两片导电片230可以恢复至初始位置，结构简单，运行稳定、可靠。
如图1-图3所示，根据本申请实施例的车辆1000的导电系统500，导电系统500包括：接地装置100和充电装置300。
其中，接地装置100为上述所述的车辆1000的接地装置100，充电装置300包括充电刀310和充电槽320，充电刀310与车辆1000的蓄能装置600连接，充电槽320与供电设备2000连接。充电槽320结构与接地槽20的结构类似，在此不再赘述。由此，供电设备2000和蓄能装置600可以通过充电刀310与充电槽320的配合实现连接，以便于对蓄能装置600进行充电。
根据本申请实施例的车辆1000的导电系统500，通过设置充电刀310和充电槽320，可以通过充电刀310和充电槽320实现供电装置与蓄能装置600之间的电连接，以便于对蓄能装置600进行充电。通过设置接地刀10和接地槽20，可以通过接地刀10和接地槽20的配合，实现车辆1000的接地，从而提高了车辆1000的安全性能。而且，车辆1000的接地装置100结构简单，运行稳定、可靠。
需要说明的是，接地槽20和充电槽320可以沿垂直于车辆1000行驶的方向并列设 置，如图1和图2所示，接地槽20可以设置于两个充电槽320之间，且接地槽20可以设于两个充电槽320的中间位置，或接地槽20可以沿垂直于车辆1000的行驶方向设于两个充电槽320的其中一侧，以提高接地槽20和充电槽320布局设计的多样性。接地刀10和充电刀310可以同步伸入至接地槽20和充电槽320内，即充电刀310伸入充电槽320内时，接地刀10也伸入接地槽20内。
接地槽20和充电槽320也可以沿车辆1000的行驶方向间隔设置，接地刀10和充电刀310可以不同步伸入接地槽20和充电槽320内。例如，沿车辆1000的行驶方向，接地槽20与充电槽320间隔设置，接地槽20的中心线可以与两个充电槽320中的其中一个的中心线重合，接地槽20的中心线也可以与两个充电槽320的中心线均不重合。此时，可以使接地刀10伸入接地槽20但充电刀310未伸入至充电槽320内，或充电刀310伸入充电槽320但接地刀10未伸入接地槽20内。接地槽也可以沿车辆1000行驶的轨迹全程设置，由此，可以在车辆1000行驶的过程中，使车辆1000始终保持接地，以提高车辆1000运行的安全性。
需要说明的是，接地槽20还可以是多个，例如，接地槽20可以是两个。沿车辆1000的行驶方向，两个接地槽20分别设置于充电槽320的两端。由此，当车辆1000沿不同方向行驶进站时，相应方向一侧的接地刀10可以与对应的接地槽20接触，以实现车身的接地，从而可以在车辆1000进站充电前将车身的静电去除，提高了车辆1000的安全性。
根据本申请的一些实施例，充电刀310可以包括：正极充电刀和负极充电刀，充电槽320可以包括：正极充电槽和负极充电槽。接地槽20与负极接地槽位于车辆1000的长度方向中心轴线的同一侧。也就是说，接地槽20可以靠近负极充电槽的一侧设置。而且，接地槽20可以与负极充电槽位于同一行驶轨迹上。
需要说明的是，接地刀10与车身之间可以通过绝缘臂固定连接，接地刀10通过连接线与车身电连接，且接地线上可以设有二极管，以实现电流从车身到接地刀10的单向导通。当充电刀310伸入对应的充电槽320内时，接地刀10可以一同伸入对应的充电槽320内。由于接地线上设有二极管，充电槽320内的电流不能经接地刀10传递至车身。而当车辆1000发生漏电时，由于车身上的电压高于负极充电槽处的电压，车身上的电流可以通过接地刀10传递至负极充电槽和负极充电刀上，从而提高了车辆1000的安全性。
根据本申请的一些实施例，如图1和图2所示，接地刀10和充电刀310可以沿车辆1000的宽度方向间隔设置，也就是说，接地刀10与充电刀310可以沿垂直于车辆 1000的行驶方向的方向间隔设置。例如图2所示，接地刀10与充电刀310可以在左右方向间隔设置。例如，接地刀10和充电刀310可以沿车辆1000的宽度方向间隔设于车辆1000底部的转向架上。由此，可以使车辆1000的导电系统500的结构紧凑、合理，有效避免了车辆1000的导电系统500与其他部件之间发生结构干涉。
根据本申请的一些实施例，如图2所示，充电刀310可以包括：正极充电刀和负极充电刀，充电槽320可以包括正极充电槽和负极充电槽。接地刀10位于正极充电刀和负极充电刀之间，接地槽20位于正极充电槽和负极充电槽之间。如图1和图2所示，接地刀10可以设于两个充电刀310之间，相应地，接地槽20设于两个充电槽320之间。由此，可以使导电系统500的结构紧凑、合理。
需要说明的是，正极充电刀可以与蓄能装置600的正极连接，负极充电刀可以与蓄能装置600的负极连接。正极充电槽可以与供电设备2000的正极连接，负极充电槽可以与供电设备2000的负极连接。当需要对蓄能装置600进行充电时，正极充电刀伸入正极充电槽内，负极充电刀伸入负极充电槽内，实现供电设备2000与蓄能装置600之间的连接，以对蓄能装置600进行充电。需要进行说明的是，附图2中描述的正和负只是为了示意性说明，并不是对本申请的正极充电刀230、负极充电刀230、正极充电槽320和负极充电槽320的具体位置的具体限定。
根据本申请的一些实施例，如图2所示，接地槽20的高度可以高于充电槽320的高度。由此，可以缩短接地槽20与接地刀10之间的距离，从而可以提高接地刀10与接地槽20之间配合的稳定性和可靠性。而且可以缩短接地刀10的长度，由此，可以提高接地刀10的刚度。
在本申请的一些实施例中，如图2所示，接地槽20可以设于车辆1000的轨道梁400上，在轨道梁的宽度方向上(例如图2所示的左右方向上)且接地槽20可以位于轨道梁400的中部。接地槽20和充电槽320可以通过固定板固定至车辆1000的轨道梁400上。接地槽20可以设于轨道梁400的中心线上，两个充电槽320可以对称设置于接地槽20的两侧。由此，便于导电系统500的布局设置。需要进行说明的是，车辆1000行驶轨道梁上，轨道梁导引车辆1000的行驶轨迹。
根据本申请的一些实施例，导电系统500还可以包括车辆定位装置700和接收装置800，车辆定位装置700设于接地槽20的下方，接收装置800设于车辆1000的下方，当接地刀10伸入接地槽20、充电刀310伸入充电槽320内时，接收装置800与定位装置感应以控制车辆1000停车。由此，通过设置车辆定位装置700和接收装置800，当车辆1000进站或行驶至充电位置时，通过接收装置800与车辆定位装置700之间的感 应，可以方便、精确地控制车辆1000的停车。车辆1000停车时，充电刀310位于对应的充电槽320内，接地刀10位于对应的接地槽20内，以对车辆1000进行接地和充电。
下面参照图1和图2以一个具体的实施例详细描述根据本申请实施例的导电系统500。值得理解的是，下述描述仅是示例性描述，而不是对本申请的具体限制。
车辆1000的导电系统500可以应用于空中巴士或其他轨道车辆上。如图1和图2所示，车辆1000的导电系统500包括：接地装置100和充电装置300。
其中，如图1和图2所示，充电装置300包括充电刀310和充电槽320，充电刀310为两个且分别为正极充电刀和负极充电刀，充电槽320为两个且分别为正极充电槽和负极充电槽。正极充电刀与车辆1000的蓄能装置600的正极连接，负极充电刀与蓄能装置600的负极连接。正极充电槽与供电设备2000的正极连接，负极充电槽与供电装置的负极连接。
两个充电刀310设于车辆1000底部的转向架导向框上，两个充电槽320通过固定板固定于车辆1000轨道梁400上。
接地装置100包括：接地刀10和接地槽20，接地刀10设于两个充电刀310之间，接地刀10包括固定部110和受流部120，固定部110和受流部120均为金属导电件，固定部110与车辆1000底部的转向架连接，受流部120与固定部110的自由端连接。受流部120沿车辆1000的行驶方向延伸，受流部120的前后两端的厚度小于受流部120中间部分的厚度。
接地槽20设于两个充电槽320之间，且接地槽20位于轨道梁400的中心线上。接地槽20通过固定板固定于轨道梁400上，且接地槽20的高度高于充电槽320。接地槽20接地，接地槽20具有槽体210，当接地刀10伸入槽体210时，接地刀10与接地槽20电连接以将车辆1000接地。
接地槽20的下方设有车辆定位装置700，相应地，车辆1000的下方设有接收装置800。当车辆1000行驶至车站或充电位置时，接地刀10伸入接地槽20内、充电刀310伸入相应的充电槽320内，接收装置800与车辆定位装置700感应并控制车辆1000停车。此时，车辆1000的静电或漏电电流可以经过接地刀10和接地槽20进行接地。供电设备2000可以通过充电刀310和充电槽320与蓄能装置600进行连接，以对蓄能装置600进行充电。
由此，通过设置充电刀310和充电槽320，可以通过充电刀310和充电槽320实现 供电装置与蓄能装置600之间的电连接，以便于对蓄能装置600进行充电。通过设置接地刀10和接地槽20，可以通过接地刀10和接地槽20的配合，实现车辆1000的接地，从而提高了车辆1000的安全性能。而且，车辆1000的接地装置100结构简单，运行稳定、可靠。
在本说明书的描述中，参考术语“一个实施例”、“一些实施例”、“示意性实施例”、“示例”、“具体示例”、或“一些示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本申请的至少一个实施例或示例中。在本说明书中，对上述术语的示意性表述不一定指的是相同的实施例或示例。而且，描述的具体特征、结构、材料或者特点可以在任何的一个或多个实施例或示例中以合适的方式结合。
尽管已经示出和描述了本申请的实施例，本领域的普通技术人员可以理解：在不脱离本申请的原理和宗旨的情况下可以对这些实施例进行多种变化、修改、替换和变型，本申请的范围由权利要求及其等同物限定。
