具体实施方式
下面详细描述本申请的实施例，所述实施例的示例在附图中示出。下面通过参考附图描述的实施例是示例性的，旨在用于解释本申请，而不能理解为对本申请的限制。
相关技术中，现有的充电枪和充电口的冷却方案，基本是各自成独立系统，只是单独冷却一方面，没有统一整合起来。再者就是做两套冷却方案，分别给整车和充电枪侧冷却，这种方式的结构复杂，使用操作相对比较麻烦，还需要占用更多的空间，同时也难以做到统一控制和管理。两套系统成本相对也比较大，两者冷却回路也很难信息交流，产生问题也难处理。
下面参考图1-图15详细描述一下根据本申请实施例的充电连接件。
如图3-图6所示，根据本申请实施例的充电连接件包括：壳体1、冷却管路2和磁性密封件，冷却管路2设置在壳体1内，而且，冷却管路2的第一端敞开设置，冷却介质可以从冷却管路2的第一端流入至冷却管路2内，从而可以保证冷却管路2内流动有冷却介质。其中，壳体1内还可以设置有接线端子，流动有冷却介质的冷却管路2可以有效降低接线端子的工作温度，而且可以避免出现接线端子过热的问题。其中，接线端子可以包括传输电流的正极接线端子和负极接线端子。此接线端子适用于直流充电口。冷却介质可以为液体，例如，水；冷却介质也可以为气体，例如，低温气体。
同理交流充电口充电接线端子也是成对出现，可能为多个，原理同上，依旧可以实施应用。其中，磁性密封件设置在冷却管路2的第一端处。磁性密封件具有密封作用，可以把冷却管路2的第一端处密封，从而可以有效防止冷却管路2内的冷却介质泄露，进而可以保证充电连接件的工作可靠性。
根据本申请的一个实施例，如图8和图9所示，磁性密封件可以包括：磁性件4和密封件5，磁性件4和密封件5均位于冷却管路2的第一端处。磁性件4具有磁性，这样可以把充电连接件的冷却管路2的冷却对接口处接的更加可靠。并且，密封件5具有密封作用，把密封件5套设在冷却管路2的第一端处，能够对冷却管路2的第一端处进行密封，在充电过程中，可以使冷却管路2保持很好的密封性，从而可以防止漏液情况发生，进而可以避免不安全情况发生。
如图3和图6所示，磁性件4和密封件5在轴向上间隔开设置，密封件5位于磁性件4的轴向外侧。这样密封件5可以将磁性件4包裹在密封件5的内侧，从而可以对磁性件4起到保护作用，进而可以提升磁性件4的使用寿命。
磁性件4和密封件5径向间隔开设置，磁性件4位于密封件5的径向外侧。其中，径向 方向是指图11中上下方向。这样设置可以进一步保证充电连接件的工作可靠性。
根据本申请的一个实施例，磁性件4设置为电磁铁，电磁铁是一种通过电流来产生磁力的器件，属于非永久磁铁，可以通过控制电流的通断来控制磁性的有无，从而可以很容易将电磁铁的磁性启动或取消。而且，电磁铁的价格便宜，可以降低制造成本。
电磁铁对应连接有线束，线束可以向电磁铁提供电能，可以随时控制电磁铁工作，此操作简单方便，可以提升客户满意度。并且，壳体1上设置有线束安装孔，线束能够安装在线束安装孔内，线束安装孔能够对线束起到位置限定作用，从而可以防止线束在充电连接件内随意晃动。另外，线束安装孔内也可以安装有通讯线束，从而可以保证充电连接件正常工作。
根据本申请的一个实施例，如图3、图5、图8和图9所示，冷却管路2可以包括：管路段31和连接段3，连接段3与管路段31相连，而且，连接段3位于轴向外侧，管路段31的外周向轴向外侧延伸，管路段31可以与连接段3形成安装磁性密封件的安装凹槽6。
磁性件4和密封件5设置在安装凹槽6内，这样安装凹槽6可以对磁性件4和密封件5起到位置固定和保护作用，可以防止磁性密封件在工作时位置变动导致冷却对接口连接不稳固。
如图3和图8所示，连接段3的截面内径小于管路段31的内径，连接段3的截面内径在轴向内侧向外侧的方向上呈递减趋势。这样设置可以提升冷却管路2的结构强度，从而可以把冷却对接口更好地连接起来。
根据本申请的一个实施例，如图3、图5、图6、图8和图9所示，连接段3和管路段31之间形成有连接部，管路段31的外周从连接部处向轴向外侧延伸，管路段31的延伸部分长度小于连接段3的长度。在充电过程中，这样设置更加适合两个充电连接件的连接段3进行连接，从而可以进一步提升充电连接件的工作性能。
根据本申请的一个实施例，如图7和图8所示，充电连接件还可以包括：单向通水膜片207，单向通水膜片207设置在冷却管路2的第一端处。其中，单向通水膜片207允许冷却介质单向流入或者单向流出冷却管路2，此单向通水膜片207是一种类似奶嘴的结构，冷却介质只能在受到一定的压力的情况下，向一个方向流通，不能反方向流通，这样可以更进一步提升充电连接件的工作性能。
冷却管路2的第一端在轴向外侧向内侧的方向上构造为渐扩状可以用于回流。在充电完成后，能够使充电连接件内残留的冷却介质从冷却管路2上渐扩状处的流出，从而可以使第二充电连接件20内不留有冷却介质。
根据本申请实施例的充电枪100，可以包括充电连接件，充电连接件设置安装在充电枪100上，在充电过程中，能够对充电枪100起到降温的作用，从而可以防止充电枪100温度 过高，进而可以保证充电安全可靠。
如图10所示，根据本申请实施例的充电系统30，可以包括：第一充电连接件10、第二充电连接件20和泵302，第一充电连接件10和第二充电连接件20可以对接，其中，第一充电连接件10和第二充电连接件20中的一个为充电插座，第一充电连接件10和第二充电连接件20中的另一个为充电枪100，这样在充电插座和充电枪100对接后，充电枪100可以为车辆充电。
如图3、图8和图9所示，第一充电连接件10可以包括：第一冷却管路和第一磁性密封件。第二充电连接件20可以包括：第二冷却管路和第二磁性密封件，第一冷却管路可有流动的冷却介质，第二冷却管路可有流动的冷却介质，第一冷却管路和第二冷却管路对接时，第一磁性密封件和第二磁性密封件磁性吸合密封。
如图10所示，在第一冷却管路和第二冷却管路对接时，泵302工作以使冷却介质进入第一冷却管路和第二冷却管路中。可以理解的是，泵302可以为冷却介质在第一冷却管路和第二冷却管路中的流动提供动力，从而可以使得冷却介质能够在第一冷却管路和第二冷却管路中有效循环流动，进而可以更好地降低第一充电连接件10和第二充电连接件20的工作温度。
另外，如图10所示，充电系统30包括存储容器303，存储器303可以与泵302通过管路连接，且泵302设置在存储器303的下游，存储容器303用于存储冷却介质。由此，泵302可以将冷却介质从存储容器303泵入第一冷却管路和第二冷却管路中，也可以将第一冷却管路和第二冷却管路中的冷却介质泵入存储容器303，这样，存储容器303可以有效地为第一冷却管路和第二冷却管路提供参与循环的冷却介质。
第一冷却管路和第二冷却管路可以有效对接，其中，第一充电连接件10上的连接段3可以为第二冷却管路用于与第二充电连接件20上的连接段3对接的端口，这样能够使得冷却介质在第一冷却管路和第二冷却管路之间连通，从而可以仅布置一个冷却源即可，而且可以有效降低接线端子和接线端子的工作温度。并且，将整个充电系统30的冷却回路连接为一个整体，只需要一个冷却回路就可以冷却整个充电回路，从而可以实现整个充电回路的系统化。
在第一充电连接件10和第二充电连接件20对接时，第一磁性密封件和第二磁性密封件可以有效对接并相互吸附，从而可以使得第一磁性密封件和第二磁性密封件有效密封第一冷却管路和第二冷却管路，进而可以提升第一充电连接件10和第二充电连接件20对接的安全性。
根据本申请的一个实施例，第一充电连接件10可以为上述的充电连接件，第二充电连接件20可以为上述的充电连接件。这样可以满足对车辆充电的工作需求。
第一冷却管路的第一端可以插入第二冷却管路的第一端。这样可以实现将第一冷却管路与第二冷却管路连接起来，从而可以实现对充电系统30的降温作用。
根据本申请的一个实施例，管路段31和连接段3可以设置为一体成型件，一体成型件的结构简单，可以省去制造零件的加工工序，从而可以进一步降低制造成本，并且，也可以防止管路段31和连接段3的连接处出现裂痕，从而可以防止漏液情况发生，进而可以提高第一充电连接件10的工作可靠性。另外，密封件5可以设置为密封圈，密封圈的密封效果好。
下面根据图10详细描述一下根据本申请实施例的第一充电连接件10和第二充电连接件20的具体工作情况。
如图10所示，在充电过程中，充电枪100插入充电插座，完成插接后，通讯端子检测完成，发送信号告知完成对接。此时充电枪100侧和充电插座侧的冷却对接口的电磁铁通电，产生磁性，两个电磁铁互相吸引，两者闭合，挤压两个密封圈，使得两侧的冷却对接口完全闭合密封。电磁铁内部的传感器实时监测两侧压力值，并传送给外部的控制器301，确保内部密封性能良好。
一切监测无误后，控制器301控制开始充电，并且开始导通冷却介质，由于第二冷却管路的端部安装有一个单向通水膜片207，水流只能单向流通并通过充电枪100侧流入到整车侧。当完成充电后，充电和冷却停止，控制器301控制外部泵302反向工作，将回路中残留冷却介质抽出后，泵302停止工作。电磁铁电源切断，电磁铁消失磁性，外部自带的电锁也同时打开，拔出充电枪100。
如图12和图13所示，根据本申请的充电枪100包括上述实施例中的充电连接件，具体地，充电枪100可以包括第一充电连接件10或第二充电连接件20。
如图14和图15所示，根据本申请的车辆1000包括上述实施例中的充电连接件，具体地，车辆可以包括第一充电连接件10或第二充电连接件20。
在本说明书的描述中，参考术语“一个实施例”、“一些实施例”、“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必须针对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一个或多个实施例或示例中以合适的方式结合。此外，在不相互矛盾的情况下，本领域的技术人员可以将本说明书中描述的不同实施例或示例以及不同实施例或示例的特征进行结合和组合。尽管上面已经示出和描述了本申请的实施例，可以理解的是，上述实施例是示例性的，不能理解为对本申请的限制，本领域的普通技术人员在本申请的范围内可以对上述实施例进行变化、修改、替换和变型。
