本申请实施例的技术方案中，将所述传感单元安装在设有所述排水沟的所述电路板上，并且将所述电路板贴附于所述导热座上，而所述导热座用于贴附和安装于其他需要使用所述传感单元的设备上。这样的设计使得，当所述传感单元周围环境的温度产生波动，从而使得空气中的水分液化成液滴。液滴附着在所述传感单元的表面时，液滴会由于重力的作用，沿所述电路板上的所述排水沟排出，防止所述传感单元由于液滴连通所述第一导电触点和第二导电触点，从而使得所述传感单元发生短路。
在一些实施例中，所述排水沟沿第一方向延伸，其中，所述第一方向为垂直于自所述第一导电触点往所述第二导电触点的方向，并且所述第一方向与所述导热座、电路板和传感单元堆叠的方向正交。通过这样的设计，所述排水沟区别于所述第一导电触点和第二导电触点，从而使得液滴在排出所述排水沟时不会连通所述第一导电触点和第二导电触点。
在一些实施例中，沿所述第一方向，所述排水沟包括依次连通的第一沟体、第二沟体和第三沟体。沿第二方向观察，所述第二沟体与所述第一导电触点和所述第二导电触点的连线重叠，所述第一沟体和所述第三沟体与所述第一导电触点和所述第二导电触点的连线错开，所述第二方向垂直于所述第一方向，并且所述第二方向垂直于所述第一导电触点和所述第二导电触点的连线的方向。本申请实施例的传感器中，依次连通的所述第一沟体、所述第二沟体和所述第三沟体将液滴排出，以防止液滴连通所述第一导电触点和所述第二导电触点。
在一些实施例中，沿所述第二方向，所述第一沟体背离所述第二沟体的一端贯穿所述电路板。本申请实施例的传感器中，通过将所述电路板贯穿，以使液滴可以沿贯穿后的所述电路板排 出。
在一些实施例中，所述导热座面向所述电路板的一表面设置有排水槽。沿第二方向观察，所述排水槽和所述排水沟至少部分重叠，其中，所述第二方向为所述电路板和所述导热座叠置的方向。本申请实施例的传感器中，在所述导热座上设置排水槽，从而增加所述排水沟的空间，提高所述传感器的排水功能。
在一些实施例中，所述导热座包括基座、第一安装部和第二安装部，所述第一安装部和第二安装部均安装于所述基座上，并且所述第一安装部和所述第二安装部相对设置，所述第一安装部和所述第二安装部与所述基座共同围合成排水槽，所述电路板安装于所述第一安装部和所述第二安装部。本申请实施例的传感器中，在所述导热座上设置排水槽，从而进一步增加所述排水沟的空间，实现所述排水槽和所述排水沟的排水功能。
在一些实施例中，沿第一方向，所述排水槽包括依次连通的第一槽体、第二槽体和第三槽体。沿第二方向观察，所述第二槽体与所述第一导电触点和所述第二导电触点的连线重叠，所述第一槽体和所述第三槽体与所述第一导电触点和所述第二导电触点的连线错开。本申请实施例的传感器中，依次连通的所述第一槽体、所述第二槽体和所述第三槽体将液滴排出，以防止液滴连通所述第一导电触点和所述第二导电触点。
在一些实施例中，所述传感器还包括第一防水件和第二防水件，所述第一防水件覆盖所述第一导电触点，以及，所述传感单元与所述第一导电触点连接的位置，所述第二防水件覆盖所述第二导电触点，以及，所述传感单元与所述第二导电触点连接的位置。本申请实施例的传感器中，将所述第一防水件和所述第二防水件分别覆盖于所述第一导电触点和所述第二导电触点，从而进一步增强所述传感器的防水功能。

在本申请实施例的描述中，技术术语“第一”“第二”等仅用于区别不同对象，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量、特定顺序或主次关系。在本申请实施例的描述中，“多个”的含义是两个以上，除非另有明确具体的限定。
在本文中提及“实施例”意味着，结合实施例描述的特定特征、结构或特性可以包含在本申请的至少一个实施例中。在说明书中的各个位置出现该短语并不一定均是指相同的实施例，也不是与其它实施例互斥的独立的或备选的实施例。本领域技术人员显式地和隐式地理解的是，本文所描述的实施例可以与其它实施例相结合。

在本申请实施例的描述中，技术术语“中心”“纵向”“横向”“长度”“宽度”“厚度”“上”“下”“前”“后”“左”“右”“竖直”“水平”“顶”“底”“内”“外”“顺时针”“逆时针”“轴向”“径向”“周向”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本申请实施例和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本申请实施例的限制。

目前，从市场形势的发展来看，动力电池的应用越加广泛。动力电池不仅被应用于水力、火力、风力和太阳能电站等储能电源系统，而且还被广泛应用于电动自行车、电动摩托车、电动汽车等电动交通工具，以及军事装备和航空航天等多个领域。随着动力电池应用领域的不断扩大，其市场的需求量也在不断地扩增。
本发明人注意到，许多电子设备在使用的过程中，常会遇到各种区别于标定工况之外的环境状况，并且电子设备中的电池、传感器、处理器、驱动器等电子元器件在工作的过程中都会产生热量。而无论是通过电子设备的散热装置主动进行换热降温，还是直接与外界环境进行换热，都容易产生气体凝华转变为液体的情况。以常见大气中的水分与传感器之间的关系为例，当大气中的水分凝华成液滴时，液滴会滴落或附着于传感器表面，此时，液滴会将传感器与电路板连接的焊脚连通，形成水膜通路，从而导致电子元件短路。
为了缓解这种液滴导致电子元件短路的问题，申请人研究发现，可以在设计上为液滴提供排出的空间。具体为在装有传感器的电路板上开设一个可以供液滴排出的空间，当液滴附着于传感器表面时，通过这个空间将液滴排出，从而解决焊脚被液滴连通导致传感器短路的问题。提高了传感器的安全性能和使用寿命。
本申请实施例公开的电池单体可以但不限用于车辆、船舶或飞行器等用电装置中。可以使用具备本申请公开的电池单体、电池等组成该用电装置的电源系统，这样，有利于缓解并自动调节电芯膨胀力恶化，补充电解液消耗，提升电池性能的稳定性和电池寿命。
本申请实施例提供一种使用电池作为电源的用电装置，用电装置可以为但不限于手机、平板、笔记本电脑、电动玩具、电动工具、电瓶车、电动汽车、轮船、航天器等等。其中，电动玩具可以包括固定式或移动式的电动玩具，例如，游戏机、电动汽车玩具、电动轮船玩具和电动飞机玩具等等，航天器可以包括飞机、火箭、航天飞机和宇宙飞船等等。
以下实施例为了方便说明，以本申请一实施例的一种用电装置为车辆1为例进行说明。
请参阅图1，图1为本申请一些实施例提供的车辆1的结构示意图。车辆1可以为燃油汽车、燃气汽车或新能源汽车，新能源汽车可以是纯电动汽车、混合动力汽车或增程式汽车等。车辆1的内部设置有电池10，电池10可以设置在车辆1的底部或头部或尾部。电池10可以用于车辆1的供电，例如，电池10可以作为车辆1的操作电源。车辆1还可以包括控制器20和马达30，控制器20用来控制电池10为马达30供电，例如，用于车辆1的启动、导航和行驶时的工作用电需求。
在本申请一些实施例中，电池10不仅可以作为车辆1的操作电源，还可以作为车辆1的驱动电源，代替或部分地代替燃油或天然气为车辆1提供驱动动力。
请参阅图2，图2为本申请一些实施例提供的电池10的结构示意图。电池10包括传感器100、电池壳200以及控制电路板300，传感器100与控制电路板300电连接，并且传感器100安装于电池壳200的内壁和/或外壁。其中，传感器100包括温度传感器、湿度传感器、光敏传感器、化学传感器、气敏传感器、压敏传感器以及磁敏传感器等。在一些实施例中，可以不设有控制电路板300，将传感器100直接与上述控制器20电连接。
对于上述传感器100，请参阅图3和图4，其分别示出了本申请其中一实施例提供的传感器100的立体图和本申请其中一实施例提供的传感器100的分解图。传感器100包括导热座110、传感单元120以及电路板130。电路板130设置于导热座110，电路板130背离导热座110的一表面设置有第一导电触点131和第二导电触点132，传感单元120分别与第一导电触点131和第二导电触点132电连接，电路板130还设置有排水沟133，排水沟133位于第一导电触点131和第二导电触点132之间。
通过在电路板130上的第一导电触点131和第二导电触点132之间设置排水沟133，从而使得当传感单元120表面附着有水滴时，可以自其所安装的电路板130上的排水沟133，将水滴排 出。从而防止水滴在第一导电触点131和第二导电触点132之间形成电流通路，导致传感单元120短路。并且传感单元120分别与第一导电触点131和第二导电触点132锡焊。
在一些实施例中，排水沟133沿第一方向X延伸。需要说明的是，如图3和图7中所示，上述第一方向X为垂直于自第一导电触点131往第二导电触点132的方向，并且第一方向X与上述导热座110、电路板130和传感单元120叠置的方向正交。具体参见图7，图中第三方向Z为自第一导电触点131往第二导电触点132的方向。而图3中第二方向Y垂直于第一方向X，并且第二方向Y垂直于第一导电触点131和第二导电触点132的连线的方向，即为垂直于X-Z平面的方向。
通过将排水沟133沿第一方向X延伸，水滴会沿着排水沟133延伸的方向排出，从而进一步提升排水沟133的排水性能。
在一些实施例中，请参阅图4，并结合其他附图。排水沟133包括沿第一方向X连通的第一沟体1331、第二沟体1332和第三沟体1333。沿第二方向Y观察，第二沟体1332与第一导电触点131和第二导电触点132的连线重叠，第一沟体1331和第三沟体1333均与第一导电触点131和第二导电触点132的连线错开。
可选地，结合第一方向X和第二方向Y观察，第一沟体1331、第二沟体1332和第三沟体1333的宽度、形状和容积相等。通过将第一沟体1331、第二沟体1332和第三沟体1333共同连通，从而使得水滴可以快速从排水沟133中排出，进一步提升排水沟133的排水性能。
可选地，请参阅图4，并结合其他附图。沿第二方向Y观察，第二沟体1332的宽度分别小于第一沟体1331的宽度以及第三沟体1333的宽度。而在本实施例中，第一沟体1331、第二沟体1332和第三沟体1333的两侧的侧壁均为弧状，从而使得第一沟体1331、第二沟体1332和第三沟体1333的两侧的侧壁可以分别连接成相对设置的弧。通过这种设计，可以使得水滴沿弧状的侧壁向外排出，并且由于第二沟体1332的宽度分别小于第一沟体1331的宽度以及第三沟体1333的宽度，利用液体的吸附性，使得液滴可以附着于第一沟体1331、第二沟体1332和第三沟体1333的两侧的侧壁以及底壁向外排出。
在一些实施例中，请参阅图5和图6，其分别示出了本申请其中另一实施例提供的传感器100的立体图和本申请其中另一实施例提供的传感器100的分解图，并结合其他附图。第一沟体1331、第二沟体1332和第三沟体1333的两侧的侧壁为直壁，并且第二沟体1332的两侧的侧壁与，第一沟体1331和第三沟体1333的两侧的侧壁之间存在夹角，以使第一沟体1331、第二沟体1332和第三沟体1333的两侧的侧壁可以呈相对设置的梯形设置，从而使得排水沟133沿第一方向X远离传感单元120处扩大，进一步提升排水沟133的排水性能。
在本实施例中，第一沟体1331背离第二沟体1332的一端，沿第二方向Y贯穿电路板130。一方面，使得电路板130和与其连接的其他电路板之间留有空隙，以使水滴可以沿这一贯穿的空隙排出，从而减少在电路板130上的留存时间，避免影响其他电子元件；另一方面，排水沟133可以直接与下方导热座110连通，从而扩大排水沟133的容积。
在本实施例中，导热座110面向电路板130的一表面设置有排水槽111；沿第二方向Y观察，排水槽111和排水沟133至少部分重叠。可以理解的是，排水槽111和排水沟133至少要有部分重叠或者部分连通，是为了将排水沟133内的水滴通过排水槽111排出，从而使得排水沟133和排水槽111之间共同配合排出水滴。
对于上述导热座110，请参阅图4，其示出了本申请其中一实施例提供的传感器100的分解图，并结合其他附图。导热座110包括基座112、第一安装部113和第二安装部114。第一安装部113和第二安装部114均安装于基座112上，并且第一安装部113和第二安装部114相对设置，第一安装部113和第二安装部114与基座112共同围合成排水槽111，电路板130安装于第一安装部113和第二安装部114。
通过将第一安装部113和第二安装部114相对设置于基座112上，并且将装有传感单元120的电路板130安装于第一安装部113和第二安装部114。一方面，基座112作为传感器100的安装基座，用于承载上述元件；另一方面，基座112用于贴附或者固定于电池10上；又一方面，在一些实施例中，基座112用作导热片，用于将温度传递至传感单元120，以便传感单元120作为温度 传感器时工作，减少空气热阻，提高温度传感器的测量精度。第一安装部113和第二安装部114还用于将传感单元120抬高。
需要说明的是，上述基座112使用柔性材料制成，并且基座112不能使用吸水材料，虽然吸水材料便于吸收排水沟133和排水槽111内的水滴，但是水作为一种热阻较大的液体，在被导热垫吸收后，容易降低传感单元120作为温度传感器时的灵敏度。第一安装部113和第二安装部114使用刚性材料制成。在一些实施例中，第一安装部113和第二安装部114可以与上述电路板130一体成型，一方面便于传感器100的生产和装配，另一方面便于传感单元120的工作。
对于上述排水槽111，请参阅图4，其示出了本申请其中一实施例提供的传感器100的分解图，并结合其他附图。排水槽111包括依次连通的第一槽体1111、第二槽体1112和第三槽体1113。沿第二方向Y观察，第二槽体1112与第一导电触点131和第二导电触点132的连线重叠，第一槽体1111与第一导电触点131和第二导电触点132的连线错开，第三槽体1113与第一导电触点131和第二导电触点132的连线错开。
可选地，沿第二方向Y观察，第二槽体1112的宽度分别小于第一槽体1111的宽度以及第三槽体1113的宽度。通过将第一槽体1111、第二槽体1112和第三槽体1113共同连通，从而使得水滴可以快速从排水槽111中排出，进一步提升排水槽111的排水性能。
可选地，沿第三方向Z观察，第二槽体1112的宽度分别小于第一槽体1111的宽度以及第三槽体1113的宽度。而在本实施例中，第一槽体1111、第二槽体1112和第三槽体1113的两侧的侧壁均为弧状，从而使得第一槽体1111、第二槽体1112和第三槽体1113的两侧的侧壁可以分别连接成相对设置的弧。通过这种设计，可以使得水滴沿弧状的侧壁向外排出，并且由于第二槽体1112的宽度分别小于第一槽体1111的宽度以及第三槽体1113的宽度，利用液体的吸附性，使得液滴可以附着于第一槽体1111、第二槽体1112和第三槽体1113的两侧的侧壁以及底壁向外排出。
在一些实施例中，请参阅图5和图6，其示出了本申请其中另一实施例提供的传感器100的立体图和本申请其中另一实施例提供的传感器100的分解图，并结合其他附图。第一槽体1111、第二槽体1112和第三槽体1113的两侧的侧壁为直壁，并且第二槽体1112的两侧的侧壁与，第一槽体1111和第三槽体1113的两侧的侧壁之间存在夹角，以使第一槽体1111、第二槽体1112和第三槽体1113的两侧的侧壁可以呈相对设置的梯形设置，从而使得排水槽111沿第一方向X远离传感单元120处扩大，进一步提升排水槽111和排水沟133的的排水性能，其中排水槽111至少部分与排水沟133连通。
在一些实施例中，请参参阅图7，其示出了本申请其中另一实施例提供的图5的A面截面图，并结合其他附图。基座112作为排水槽111的槽底，基座112上设有至少一个排水部1121，排水部1121的第一端设置于第二槽体1112内，排水部1121的第二端设置于第一槽体1111和/或第三槽体1113远离第二槽体1112的一端。将传感单元120沿第二方向投影至基座112，排水部1121的第一端设置于传感单元120的投影内，排水部1121的第二端远离传感单元120的投影。并且排水部1121与X-Z平面具有夹角，排水部1121的第一端相对第二端靠近传感单元120。从而使得排水槽111的槽底具有斜度，以加快水滴排出。可选地，基座上设置有两个排水部1121，并且两排水部1121相对设置，一排水部1121的第一端与另一排水部1121的第一端连接，以加快水滴沿第一槽体1111和第三槽体1113排出。
在一些实施例中，如图3所示，传感器100还包括第一防水件140和第二防水件150。第一防水件140覆盖第一导电触点131，以及，传感单元120与第一导电触点131连接的位置，第二防水件150覆盖第二导电触点132，以及，传感单元120与第二导电触点132连接的位置。从而防止第一导电触点131和第二导电触点132的触点腐蚀。可选地，第一防水件140和第二防水件150为使用防水胶直接涂覆于第一导电触点131和第二导电触点132的表面，或者，第一防水件140和第二防水件150为使用三防漆直接涂覆于第一导电触点131和第二导电触点132的表面。
根据本申请的一些实施例，本申请还提供了一种电池10，包括以上任一方案的传感器100，以及电池壳200。传感器100安装于电池壳200的内壁和/或外壁。
根据本申请的一些实施例，本申请还提供了一种用电设备，图未示，包括以上任一方案所述的传感器100和/或上述电池10。
根据本申请的一些实施例，参阅3和图4。本申请提供了一种传感器100。传感器100包括导热座110、传感单元120以及电路板130。电路板130设置于导热座110，电路板130背离导热座110的一表面设置有第一导电触点131和第二导电触点132，传感单元120分别与第一导电触点131和第二导电触点132焊接，电路板130还设置有排水沟133，排水沟133位于第一导电触点131和第二导电触点132之间。并且排水沟133包括第一沟体1331、第二沟体1332以及第三沟体1333，其中沿第二方向Y观察，第二沟体1332的宽度小于第一沟体1331和第三沟体1333的宽度，第二沟体1332的两侧的侧壁与第一沟体1331的两侧的侧壁和第三沟体1333的两侧的侧壁分别连接呈弧状。沿第二方向Y，第一沟体1331、第二沟体1332和第三沟体1333均贯穿电路板130，从而使得排水沟133和排水槽111连通。而导热座110由基座112、第一安装部113和第二安装部114组成，同时基座112、第一安装部113和第二安装部114共同围合成一排水槽111。排水槽111又包括第一槽体1111、第二槽体1112以及第三槽体1113，第二槽体1112的宽度小于第一槽体1111和第三槽体1113的宽度，第二槽体1112的两侧的侧壁与第一槽体1111的两侧的侧壁和第三槽体1113的两侧的侧壁分别连接呈弧状。
可选地，沿第二方向Y，第一沟体1331和第三沟体1333贯穿电路板130，从而使得电路板130上仍保留第二沟体1332或者不设置第二沟体1332，从而提升电路板130的强度，以提高传感器100的使用寿命。
最后应说明的是：以上各实施例仅用以说明本申请的技术方案，而非对其限制；尽管参照前述各实施例对本申请进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分或者全部技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本申请各实施例技术方案的范围，其均应涵盖在本申请的权利要求和说明书的范围当中。尤其是，只要不存在结构冲突，各个实施例中所提到的各项技术特征均可以任意方式组合起来。本申请并不局限于文中公开的特定实施例，而是包括落入权利要求的范围内的所有技术方案。
