目前，从市场形势的发展来看，电动车辆成为汽车产业可持续发展的重要组成部分。为了解决充电时间较长和续航里程较短问题，电动车辆的电池快换方案应运而生，在一定程度上缓解了现有充电速度慢的问题。
在电动车辆进行快换作业的过程中，连接器暴露于外，易受损，安全性降低。
发明人经过研究发现，导致上述问题的原因在于由于换电作业中电池并不是始终与车辆本体装配在一起，在电池存储、运输以及快换过程中，连接器暴露于外界，易被外界污染物或灰尘进入，影响连接器本身的性能，比如造成连接器中的高低压端子的电阻增大或液冷接头被堵塞，导致连接器受损，安全性降低。
基于上述考虑，为解决现有技术中连接器易受损安全性降低的问题，发明人经过深入研究，设计了一种第一连接器。第一连接器用于与第二连接器插接配合。第一连接器包括第一连接器本体和防护盖。第一连接器本体具有供第二连接器插入的开口。防护盖可活动地安装于第一连接器本体，用于覆盖开口。其中，防护盖被配置为在第一连接器和第二连接器插接时，被第二连接器推动以打开开口。
在第一连接器未与第二连接器插接时，例如在存储或运输时，防护盖会覆盖开口，避免开口暴露于外界。在第一连接器和第二连接器插接时，防护盖随第二连接器的插接动作而被推动，从而打开开口，暴露出开口供第二连接器插入，实现第一连接器和第二连接器的连接。由于第一连接器本体的开口是在与第二连接器插接时被打开的，故能够有效地防止外部污染物进入开口，杜绝外部污染物影响第一连接器本体本身性能的情况发生，进而避免第一连接器本体受损，保证第一连接器本体的安全性，使得电池和车辆本体之间正常工作。相比于通过测距传感器模块、电机控制系统、压力传感器模块在内的控制系统控制防护盖活动以对第一连接器本体进行防护的情况，防护盖可活动的设置于第一连接器本体且通过第二连接器的推动以实现对第一连接器本体进行防护，具有结构简单、制造及运行成本低的优点。
本申请提供了一种第一连接器，其可以应用于电池，也可以应用于各种使用电池的设备，例如车辆、船舶或飞行器等。当第一连接器应用于电池时，电池通过第一连接器与用电设备本体插接，从而使得电池为用电设备本体供电。例如，当用电设备本体为车辆，第一连接器具有高低压端子和液冷接头，车辆具有第二连接器，第二连接器具有对应的高低压端子和液冷接口，通过第一连接器和第二连接器的插接配合，使得高低压端子和液冷接头能够同时连接，使得车辆和电池之间形成完整的高低压系统和完整的液冷系统，使得电池为车辆供电。当第一连接器应用于用电设备本体时，用电设备本体通过第一连接器与电池插接，使得电池为用电设备供电。例如，当用电设备为车辆，第一连接器具有高低压端子和液冷接头，电池具有第二连接器，第二连接器具有对应的高低压端子和液冷接口，通过第一连接器和第二连接器的插接配合，使得高低压端子和液冷接头能够同时连接，使得车辆和电池之间形成完整的高低压系统和完整的液冷系统，使得电池为车辆供电。
下文以用电设备本体为车辆1000为例进行说明。请参照图1，图1为本申请一些实施例提供的车辆1000的结构示意图。
车辆1000的内部可以设置控制器200、马达300和电池100，控制器200用来控制电池100为马达300供电。例如，在车辆1000的底部或车头或车尾可以设置电池100。电池100可以用于车辆的供电，例如，电池100可以作为车辆1000的操作电源，用于车辆1000的电路系统，例如，用于车辆1000的启动、导航和运行时的工作用电需求。在本申请的另一实施例中，电池100不仅仅可以作为车辆1000的操作电源，还可以作为车辆1000的驱动电源，替代或部分地替代燃油或天然气为车辆1000提供驱动动力。
电池100可以从车辆上拆卸下来，以实现车辆1000的换电池操作。当电池能量耗尽时，能量耗尽的电池可被拆卸，换上另一个电池100，以继续为车辆1000供电。
连接器作为电池端的连接结构，在电池100安装于车辆的过程中，连接器会与车辆的连接结构插接配合，以实现电池为车辆供电。
根据本申请的一些实施例，参照图2-图4，图2为根据本申请一些实施例的第一连接器10在开口110被覆盖时的立体图，图3为根据本申请一些实施例的第一连接器10在开口110被打开时的立体图，图4为根据本申请一些实施例的第二连接器20与第一连接器10插接时的立体图。第一连接器10用于与第二连接器20插接配合。第一连接器10包括第一连接器本体11和防护盖12。第一连接器本体11具有供第二连接器20插入的开口110。防护盖12可活动地安装于第一连 接器本体11，用于覆盖开口110。其中，防护盖12被配置为在第一连接器10和第二连接器20插接时，被第二连接器20推动以打开开口110。
第一连接器10用于第二连接器20插接配合。第一连接器10可以设置于电池，第二连接器20可以设置于用电设备本体；或者第一连接器10可以设置于用电设备本体，第二连接器20可以设置于电池。第一连接器本体11为与第二连接器20插接配合的主体结构，第一连接器本体11中可设置有高低压端子和/或液冷接头(在图3中，示例性地指出高低压端子11a)，以在第一连接器10和第二连接器20插接到位时，与第二连接器20对应的高低压端子和/或液冷接头，以实现第一连接器10和第二连接器20之间形成完整的高低压系统和/或完整的液冷系统。第一连接器本体11上设置的开口110，用于暴露出高低压端子和/或液冷接头，供第二连接器20插入。
防护盖12为可活动地设置于第一连接器本体11上的部件，用于覆盖开口110以保护第一连接器本体11的内部，例如避免高低压端子和/或液冷接头与外界接触，或者在第二连接器20的推动下打开开口110，以暴露出第一连接器本体11的内部，例如暴露出高低压端子和/或液冷接头，以供第二连接器20插入。
在第一连接器10未与第二连接器20插接时，例如在存储或运输时，防护盖12会覆盖开口110，避免开口110暴露于外界。在第一连接器10和第二连接器20插接时，防护盖12随第二连接器20的插接动作而被推动，从而打开开口110，暴露出开口110供第二连接器20插入，实现第一连接器10和第二连接器20的连接。由于第一连接器本体11的开口110是在与第二连接器20插接时被打开的，故能够有效地防止外部污染物进入开口110，杜绝外部污染物影响第一连接器本体11本身性能的情况发生，进而避免第一连接器本体11受损，保证第一连接器本体11的安全性，使得电池和用电设备本体正常工作。同时，相比于通过测距传感器模块、电机控制系统、压力传感器模块在内的控制系统控制防护盖活动以对第一连接器本体11进行防护的情况，通过第二连接器20的推动以实现防护盖12的活动进而对第一连接器本体进行防护，具有结构简单、制造及运行成本低的优点。
根据本申请的一些实施例，可选地，防护盖12可转动地安装于第一连接器本体11，防护盖12被配置为在第二连接器20与第一连接器10插接时，被第二连接器20推动旋转以打开开口110，防护盖12的旋转轴线与第二连接器20的插入方向垂直。
防护盖12可转动地安装于第一连接器本体11，指防护盖12通过相对于第一连接器本体11转动实现对开口110的覆盖或者打开开口110。
可选地，防护盖12也可以通过其他方式与第一连接器本体11可活动地连接，例如防护盖12沿垂直于第二连接器20的插入方向可滑动地安装于第一连接器本体11，同样能够实现防护盖12对开口110的覆盖和打开效果。
防护盖12被第二连接器20推动时能够较第一连接器本体11旋转，以打开开口110，供第二连接器20插入于开口110中。通过将防护盖12的旋转轴线设置为与第二连接器20的插入方向垂直，能够使得防护盖12在旋转时不对第二连接器20的插入造成干扰，保证第二连接器20能够顺利地插入于开口110中。
根据本申请的一些实施例，可选地，第一连接器本体11包括端面111和外周面112，开口110设置于端面111，外周面112围设于端面111，在防护盖12覆盖开口110时，防护盖12的一端凸出于第一连接器本体11的外周面112，以供第二连接器20推动旋转。
第一连接器本体11的端面111可以为第一连接器本体11在与第二连接器20配合时，与第二连接器本体22对接的一端表面。第一连接器本体11的外周面112可以围设于端面111的外表面。
“在防护盖12覆盖开口110时，防护盖12的一端凸出于第一连接器本体11的外周面112”，指防护盖12的一端会凸出于第一连接器本体11的外周面112，以可以在第二连接器20推动防护盖12时，推力的作用位置为该凸出于第一连接器本体11外周面112的部位，以使得防护盖12可以发生旋转。
可选地，防护盖12可以设置在端面111，防护盖12的旋转轴线位于端面111之上。或者说，防护盖12可以设置在外周面112，防护盖12的旋转轴线可以穿过外周面112，例如防护盖12可以包括盖体120和支点部121，盖体120为板状，支点部121包括与盖体120垂直连接的支撑件122，在外周面112可设置有凹槽(图中未示出)，支撑件122可设置有凸块123(在图2-图4中未示出)，凸块123可转动地设置在凹槽中，第二连接器20具有顶推部21，如图4，顶推部21为与防护盖12对应的部件，可以为板状，用于推动防护盖12的盖体120绕凹槽旋转，以打开开口110。
通过将防护盖12的一端设置为凸出于第一连接器本体11的外周面112，能够使得该凸出于第一连接器本体11的外周面112的部分被第二连接器20推动，以使得防护盖12向第一连接器本体11的外侧发生旋转，从而打开位于端面111的开口110，并形成一个沿第二连接器20插入方向延伸的通道，以供第二连接器20移动并插入于开口110中。
根据本申请的一些实施例，请参见图5-图7，图5为根据本申请一些实施例的第一连接器10在开口110被覆盖时的立体图，图6为根据本申请一些实施例的第二连接器20与第一连接器10插接时的立体图，图7为根据本申请一些实施例的第一连接器10的开口110被第二连接器20打开时的立体图。防护盖12可滑动地安装于第一连接器本体11，防护盖12被配置为在被第二连接器20推动旋转后继续被第二连接器20推动，以沿第二连接器20的插入方向滑动。
“防护盖12可滑动地安装于第一连接器本体11”，指防护盖12在可旋转地与第一连接器本体11连接的条件下，还能够相对于第一连接器本体11滑动。
通过将防护盖12设置可滑动地安装于第一连接器本体11，能够使得防护盖12在被第二连接器20推动旋转后继续被第二连接器20推动而滑动，以避免对第二连接器20沿插入方向的移动造成干扰，使得第二连接器20插入于开口110中。请结合图3和图7，对比防护盖12不与第一连接器本体11相对滑动的方案和防护盖12与第一连接器本体11相对滑动的方案，在图3中可知，当防护盖12被旋转以打开开口110后，在第二连接器20的插入方向，防护盖12会在面向第二连接器20的方向具有一定的高度，会对第二连接器20的插入造成干涉，因此在图3所示的方案中，需要在第二连接器20上设置容纳防护盖12的腔室以解决干涉问题，因此由于需对第二连接器20进行额外设置腔室，故会提高第二连接器20的制造成本。而在图7中，由于防护盖12可随第二连接器20的插入而滑动，故不会对第二连接器20的插入造成干涉，较防护盖12不与第一连接器本体11相对滑动的方案，能够降低制造成本。
根据本申请的一些实施例，第一连接器本体11包括端面111和外周面112，开口110设置于端面111，外周面112围设于端面111，外周面112上设置有沿第二连接器20的插入方向延伸的第一滑槽113，防护盖12可滑动地配合于第一滑槽113。
将第一滑槽113的相对的两个端点分别限定为第一端点1130和第二端点1131，第一滑槽113为由第一端点1130沿第二连接器20的插入方向延伸至第二端点1131的槽状结构。第一滑槽113可以使得防护盖12沿第二连接器20的插入方向滑动。
通过在第一连接器本体11的外周面112上设置第一滑槽113，能够使得防护盖12在被第二连接器20推动下平稳地沿第二连接器20的插入方向滑动。
根据本申请的一些实施例，参见图8，图8为根据本申请一些实施例的防护盖12的立体图。防护盖12包括盖体120和支点部121，盖体120用于覆盖开口110，支点部121固定于盖体120，且支点部121可转动并可滑动地配合于第一滑槽113，防护盖12被配置为在第一连接器10和第二连接器20插接时，被第二连接器20推动，以绕支点部121旋转并沿第一滑槽113滑动。
盖体120可以为板状，从而能够贴合于第一连接器本体11的端面111以紧密的覆盖开口110，进而保护第一连接器10内部。
支点部121可以为与盖体120连接的部件，且支点部121为与第一滑槽113旋转并滑动配合的部件。可选地，支点部121可以包括支撑件122和凸块123，支撑件122可与盖体120相互垂直连接，凸块123设置在支撑件122上且凸块123的旋转轴线垂直于第二连接器20的插入方向，凸块123设置在第一滑槽113内且可在第一滑槽113内旋转并滑动。可选地，第二连接器20具有顶 推部21，如图6和图7，顶推部21为与防护盖12对应的部件，可以为板状，用于推动防护盖12的盖体120绕凹槽旋转，以打开开口110。
防护盖12结构简单，便于制造。盖体120跟随支点部121活动，能够做出覆盖开口110、打开开口110以及沿第一滑槽113滑动的动作，以实现对第一连接器本体11内部的保护、因第二连接器20的推动而自动打开开口110以供第二连接器20插入、以及因第二连接器20的推动而滑动以避免对第二连接器20的插入动作造成干扰的效果。
根据本申请的一些实施例，防护盖12包括两个支点部121，两个支点部121沿盖体120的宽度方向相对设置，第一滑槽113与支点部121对应设置，每个支点部121可转动并可滑动地配合于对应的第一滑槽113内。
“第一滑槽113与支点部121对应设置”，指在盖体120的宽度方向上，第一连接器本体11相对的两个面分别设置有第一滑槽113，以与对应的支点部121配合。
可选地，第一连接器本体11可设置有第二滑槽114，第二滑槽114连通第一连接器本体11的端面111和第一滑槽113，用于防护盖12的装配，即防护盖12的支点部121可先由第二滑槽114和端面111的第一端点1130的交汇的位置进入第二滑槽114，可沿第二滑槽114移动以装配于第一滑槽113中。
通过在盖体120宽度方向上相对设置两个支点部121，在第一连接器本体11上对应地设置两个第一滑槽113，以提高防护盖12与第一连接器本体11之间的稳定性，使得防护盖12在第二连接器20的推动下平稳地旋转并滑动，能够提高防护盖12的使用寿命，进而提高第一连接器10的使用寿命。
根据本申请的一些实施例，请结合图6-图8。防护盖12背离第一连接器本体11的一侧设置有第一卡接部124，第一卡接部124被配置为在防护盖12被第二连接器20推动旋转时，与第二连接器20上的第二卡接部210配合，以使防护盖12能够被第二连接器20推动，以沿第二连接器20的插入方向滑动。
第一卡接部124为设置于防护盖12背离于第一连接器本体11一侧的，并用于与第二连接器20上的顶推部21上的第二卡接部210卡接的部件。第一卡接部124可以为卡块，第二卡接部210可以设置于顶推部21上的卡槽。
通过设置第一卡接部124以与第二连接器20上的第二卡接部210配合，能够使得在第一连接器10和第二连接器20插接时，第一连接器10能够因第一卡接部124和第二卡接部210的卡接而在第二连接器20的推动下沿插入方向滑动。同时，在第二连接器20在拔出于第一连接器10时，顶推部21能够带动防护盖12活动以实现防护盖12对开口110的自动闭合，进而实现在换电作业中的自动防护，即在第二连接器20和第一连接器10相互脱离时，防护盖12被顶推部21拉动以向插入方向相反的方向滑动，直至防护盖12滑动至止位(第一端点1130)并向开口110的方向旋转且第一卡接部124和第二卡接部210相互脱离，最终防护盖12可覆盖于开口110，避免外部污染物进入第一连接器本体11内部。
可选地，第一卡接部124背离于第一连接器本体11外周面112的一端形成有斜面1240，设置斜面1240能够让第一卡接部124轻易地脱离于第二卡接部210，以利于实现防护盖12的自动闭合。
本申请对防护盖12的数量不进行限制，其可以为一个、两个、三个或四个等。根据本申请的一些实施例，结合图9，图9为根据本申请一些实施例的第一连接器10的示意图。第一连接器10包括两个防护盖12，两个防护盖12对开设置且共同覆盖开口110。
两个防护盖12对开设置，指两个防护盖12沿第一连接器本体11在防护盖12宽度方向上的中心线上对称设置，以共同覆盖或打开开口110。
较只设置一个防护盖12的方案，设置两个防护盖12，能够减小防护盖12由覆盖开口110的状态切换为打开开口110的状态的活动路径，以避免活动路径过大对第二连接器20的插入造成干涉的情况发生。同时较设置多于两个防护盖12的方案，设置两个防护盖12，能够有效地降低第 一连接器10的制造成本。
可选地，参见图10，图10为图9中Ⅹ处的放大图。对开设置的两个防护盖12相互面向的端部分别设置有阶梯凸起1200，即盖体120的端部设置有阶梯凸起1200，以在两个防护盖12覆盖开口110时，两个防护盖12可通过各自的阶梯凸起1200相互契合，以提高对开口110的防护效果。
根据本申请的一些实施例，两个防护盖12相互靠近的一端分别设置有第一磁吸件(图中未示出)和第二磁吸件(图中未示出)；当两个防护盖12覆盖开口110时，第一磁吸件和第二磁吸件相互吸附。
