Description

电连接装置及其进水检测方法
本申请要求申请日为2020/9/30的中国专利申请2020110568666的优先权。本申请引用上述中国专利申请的全文。
技术领域
本发明属于换电设备的智能检测领域，特别涉及一种电连接装置及其进水检测方法。
背景技术
为了行车安全，电动汽车对电连接装置的密封性有严格的要求，换电版的电动汽车由于电池经常拆装，每次拆装都会拉扯到用于密封车端和电池端的电连接装置的密封圈，密封圈经多次拉扯后，容易导致密封效果下降，而车辆在行驶过程中，车端连接器和电池端连接器如果密封失效，一旦车辆路经涉水路段时，水进入到两个连接器对接形成的密封腔体里面，则易引起行车的不安全性。此外，在对电动汽车进行换电操作时，也可能因其他原因导致安装电池包时，使得两个连接器之间的密封腔体内进水，然而目前的快换连接器结构对这种进水风险无法识别。
2020年7月7日公开的中国发明专利CN201811642277.9公开了一种电连接器，该电连接器为快换连接器的电池端连接部件，用于与电池包连接，该电连接器上设有一密封检测装置，检测的是该电连接器和车端电连接器对接电连接后形成的腔体内的气压。但是当并非因密封不好导致进水的情况，例如换电操作时因其他原因导致安装电池包时，两个连接器之间的密封腔体内进水，此时检测腔体内的气压是无法获知进水风险的。
发明内容

较佳地，所述进水检测方法包括：
检测所述封闭腔体内的进水是否达到预设高度，若是，则生成触发信号。
电池端电连接装置和车端电连接装置配合后的封闭腔体的进水量达到一定高度后，才确认存在一定的风险，基于对进水高度的限定及检测，可以更精准的对进水风险进行识别。
较佳地，在生成触发信号后，所述进水检测方法还包括：
根据所述触发信号发出警示信息。
当检测到封闭腔体进水后，根据触发信号发出警示信息，以及时提醒用户存在进水风险，进而能够便于用户对电连接装置件进行及时维修，确保后续行车的安全性。
一种电连接装置，所述电连接装置包括相互配合实现电连接的车端电连接装置和电池端电连接装置，所述车端电连接装置和电池端电连接装置配合 实现电连接时，通过密封件分别连接所述车端电连接装置和所述电池端电连接装置的配合端以形成封闭腔体，所述电连接装置还包括至少一个检测元件；
所述检测元件包括检测部，所述检测部伸入所述封闭腔体内；
所述检测元件用于实现上述的电连接装置的进水检测方法。
检测部件伸入所述封闭腔体内，对封闭腔体进行进水检测，使得电连接装置根据进水生成的触发信号实现水密性的主动判断，能够及时发现电连接装置换电后的水密性能，也可以检测出因换电操作引起的进水情况，进一步提高行车的安全性。
较佳地，所述检测元件安装在所述车端电连接装置上，所述检测部伸入所述封闭腔体的车端电连接装置和电池端电连接装置之间的电连接区域。
车端电连接装置和电池端电连接装置之间的电连接区域属于高风险区域，一旦进水，对整个电连接装置的性能影响较大，因此，检测部特别设置伸入所述封闭腔体的车端电连接装置和电池端电连接装置之间的电连接区域，以提高检测的精准度。
较佳地，所述检测元件还包括信号发生部；
所述信号发生部与所述检测部相连，用于在检测部检测到所述封闭腔体内进水后生成触发信号。
较佳地，所述检测部件还包括信号传输部；
所述信号传输部分别与所述信号发生部和外部控制器相连，用于将所述信号发生部生成的触发信号发送至外部控制器。
检测元件的信号发生部和信号传输部配合使用，发生部用于在检测到进水时及时生成触发信号，并通过信号传输部及时的发送至外部控制器，以供外部控制器及时发现电连接装置换电后的水密性能。
较佳地，所述检测部包括两个探针，所述两个探针自所述车端电连接装置与所述电池端连接装置对接的一侧伸出至所述封闭腔体内；
所述两个探针用于在接触水的状态下导通；

所述电源输入部与所述车端电连接装置的低压供电线连接，以给所述检测元件供电。
为保证检测部件能够持续工作，通过车端电连接装置的低压供电线为检测部件供电。
较佳地，所述两个探针伸出所述车端电连接装置的长度小于所述车端电连接装置的导电极柱的长度。
通过将探针伸出车端电连接装置的长度小于导电极柱的长度，使得探针的设置不会影响到车端电连接装置和电池端电连接装置中导电极柱对接，也可以保护探针不易被电池端电连接装置的导电极柱碰触而损坏。
较佳地，所述两个探针的高度低于所述车端电连接装置的导电极柱的高度。
车端电连接装置和电池端电连接装置之间的电连接区域属于高风险区域，一旦进水，对整个电连接装置的性能影响较大，而车端电连接装置在使用状态时，导电极柱所在侧面为垂直或接近垂直于底面，因而电连接区域的垂直方向上要确保进水检测的有效性，因此，在对探针的高度设置时，需要两个探针的高度低于所述车端电连接装置的导电极柱的高度，以便在水还未浸湿导电极柱时便可检测到危险。
较佳地，所述车端电连接装置包括壳体，所述检测元件连接于所述壳体 内部；
和/或，
所述检测元件为水浸传感器；
和/或，
所述触发信号为干接点信号。
本申请采用水浸传感器作为检测元件，简单方便，成本较低。
本发明的积极进步效果在于：通过对封闭腔体内是否进行水进行实时检测，能够有效、主动、快速判断连接器的水密性，当检测到封闭腔体进水后，可以根据触发信号发出警示信息，以及时提醒用户存在进水风险，进而能够便于用户对电连接装置件进行及时维修，进一步提高行车的安全性。

步骤20、生成触发信号；
步骤30、根据触发信号发出警示信息。
本实施例中，步骤20还可以包括以下实现方式：
检测封闭腔体内的进水是否达到预设高度。
本实施例中，通过对封闭腔体内是否进行水进行实时检测，能够有效、主动、快速判断连接器的水密性，也可以检测出因换电操作引起的进水情况，当检测到封闭腔体进水后，可以根据触发信号发出警示信息，以及时提醒用户存在进水风险，进而能够便于用户对电连接装置件进行及时维修，进一步提高行车的安全性。
实施例2
一种电连接装置，如图2所示，所述电连接装置包括相互配合实现电连接的车端电连接装置1和电池端电连接装置2，车端电连接装置1和电池端电连接装置2配合实现电连接时，通过密封件分别连接车端电连接装置1和电池端电连接装置2的配合端以形成封闭腔体，如图3-4所示，电连接装置还包括至少一个检测元件3；检测元件3为水浸传感器；触发信号为干接点信号。
检测元件3包括检测部31，检测部31伸入封闭腔体内；检测元件3用于实现实施例1的电连接装置的进水检测方法。其中，检测部31件伸入封闭腔体内，对封闭腔体进行进水检测，使得电连接装置根据进水生成的触发 信号实现水密性的主动判断，能够及时发现电连接装置换电后的水密性能，进一步提高行车的安全性。
车端电连接装置1包括壳体11，检测元件3连接于壳体11内部。
检测元件3安装在车端电连接装置1上，检测部31伸入封闭腔体的车端电连接装置1和电池端电连接装置2之间的电连接区域4。需要说明的是，车端电连接装置1和电池端电连接装置2之间的电连接区域4属于高风险区域，一旦进水，对整个电连接装置的性能影响较大，因此，检测部31特别设置伸入封闭腔体的车端电连接装置1和电池端电连接装置2之间的电连接区域4，以提高检测的精准度。
如图5所示，检测元件3还包括信号发生部32；信号发生部32与检测部31相连，用于在检测部31检测到封闭腔体内进水后生成触发信号。
检测部31件还包括信号传输部33；信号传输部33分别与信号发生部32和外部控制器相连，用于将信号发生部32生成的触发信号发送至外部控制器。信号传输部33与车端电连接装置1的低压信号线连接，以通过低压信号线将触发信号传输给外部控制器。
需要说明的是，检测元件3的信号发生部32和信号传输部33配合使用，发生部用于在检测到进水时及时生成触发信号，并通过信号传输部33及时的发送至外部控制器，以供外部控制器及时发现电连接装置换电后的水密性能。
检测部31件还包括电源输入部34；电源输入部34与车端电连接装置1的低压供电线连接，以给检测元件3供电。
需要说明的是，前述车端电连接装置1的低压信号线和低压供电线，在实际中均为车端电连接装置1的PIN脚(或者称为引脚、管脚)，该车端电连接装置1的结构可以参考公开文献CN109119792A中所述的车端电连接器的结构，该车端电连接器具有20个低压PIN脚，其中PIN脚3和PIN脚4便可作为低压供电线与电源输入部34连接，PIN脚11和PIN脚12则可作 为低压信号线与信号传输部33连接。
检测部31包括两个探针，两个探针自车端电连接装置1与电池端连接装置对接的一侧伸出至封闭腔体内；两个探针用于在接触水的状态下导通。
如图6-7所示，为了使得探针的设置不会影响到车端电连接装置和电池端电连接装置中导电极柱对接，也可以保护探针不易被电池端电连接装置的导电极柱碰触而损坏，两个探针伸出车端电连接装置1的长度小于车端电连接装置1的导电极柱12的长度，由于导电极柱12有若干个，因此优选两个探针伸出车端电连接装置1的长度小于最短的导电极柱的长度。
车端电连接装置在使用状态时，导电极柱所在侧面通常为垂直或接近垂直于底面，为在电连接区域4中垂直方向上确保进水检测的有效性，两个探针的高度低于车端电连接装置1的导电极柱12的高度。使得当电连接装置安装在车上时，探针相对离地近一点，车端电连接装置1的导电极柱一般存在有多个，其中高压极柱两个、低压极柱若干，两个探针的高度优选地低于最低的那个导电极柱的高度。
信号发生部32用于在两个探针导通时生成触发信号。
本实施例中，通过检测元件3对封闭腔体内是否进行水进行实时检测，能够有效、主动、快速判断连接器的水密性，当检测到封闭腔体进水后，可以根据触发信号发出警示信息，以及时提醒用户存在进水风险，进而能够便于用户对电连接装置件进行及时维修，进一步提高行车的安全性。
实施例3
一种电连接装置，所述电连接装置包括车端电连接装置和电池端电连接装置，如图8所示，以车端电连接装置1为例，电连接装置还包括至少一个检测元件3。
检测元件3包括检测部31，检测部31伸入车端电连接装置1内部；检测元件3用于实现车端电连接装置的进水检测。
检测部31包括两个探针，两个探针伸入至车端电连接装置1内部；两 个探针用于在接触水的状态下导通，生成触发信号。
检测元件还包括信号发生部；信号发生部与检测部相连，用于在检测部检测到封闭腔体内进水后生成触发信号。
检测部件还包括信号传输部；信号传输部分别与信号发生部和外部控制器相连，用于将信号发生部生成的触发信号发送至外部控制器。信号传输部与车端电连接装置的低压信号线连接，以通过低压信号线将触发信号传输给外部控制器。
检测部件还包括电源输入部；电源输入部与车端电连接装置的低压供电线连接，以给检测元件供电。
本实施例中，通过检测元件对电连接装置内是否进行水进行实时检测，能够有效、主动、快速判断连接器的水密性，当检测到电连接装置进水后，可以根据触发信号发出警示信息，以及时提醒用户存在进水风险，进而能够便于用户对电连接装置件进行及时维修，进一步提高行车的安全性。
本实施例3与实施例2的区别在于，检测部31伸入了车端电连接装置1的内部而非车端电连接装置1和电池端电连接装置2配合电连接后形成的封闭腔体内。
虽然以上描述了本发明的具体实施方式，但是本领域的技术人员应当理解，这仅是举例说明，本发明的保护范围是由所附权利要求书限定的。本领域的技术人员在不背离本发明的原理和实质的前提下，可以对这些实施方式做出多种变更或修改，但这些变更和修改均落入本发明的保护范围。
