Description
本发明涉及电池设备技术领域，具体而言，涉及一种电池外壳、电池组件、电子装置和电池的组装方法。
在大型电动设备，例如农业无人机上，都需要使用大容量的锂电芯电池，以方便为设备提供电力。
传统方式的电池电芯的外部大多采用包覆有PVC膜(聚氯乙烯膜)或者采用一体成型的保护壳对电芯进行防护，通常这些防护方式的包覆膜或保护壳都会与电芯形成紧密接触进而包裹电芯进行保护。而对于大容量的锂电芯而言，由于电芯的体积较大且使用环境较为恶劣，电芯极易发生窜动，此时，会使得PVC膜极易因外力被刺破或者电芯与保护壳一同受挤压产生变形，这就有可能导致锂电池电芯内部的正负极靠近，从而发生短路起火甚至引起爆炸。对于大容量的电池而言，一旦发生起火或者爆炸，其后果难以想象，因此亟待解决这种由于防护结构设计不合理造成的安全隐患。
发明内容
本发明旨在至少解决现有技术或相关技术中存在的由于大容量锂电池电芯防护结构设计不合理导致的电池容易发生爆炸的技术问题。

在下面的描述中阐述了很多具体细节以便于充分理解本发明，但是，本发明还可以采用其他不同于在此描述的其他方式来实施，因此，本发明的保护范围并不受下面公开的具体实施例的限制。
下面参照图1至图12描述根据本发明一些实施例所述的电池外壳、电池组件、植保无人机和电池的安装方法。
本发明的第一方面实施例提供了一种电池外壳，具体如下：
如图1至图11所示，本发明的一个实施例提供了一种电池外壳，该电 池外壳用于保护电池电芯，具体地，是大容量的锂电池电芯。本实施例的电池外壳包括：电芯上盖12，用于盖设于电芯10的上方；电池上盖14、电池下盖16和用于围设在电芯10四周的多个侧板18。电池下盖16和电芯上盖12上均开设有用于定位侧板18的侧板定位部24，多个侧板18的边缘与电池下盖16的侧板定位部相配合，电芯上盖12通过侧板定位部24定位设置在多个侧板18的上端，电池上盖14盖设于电芯上盖12的上方用于密封整个电池外壳。
本发明提供的电池外壳，通过采用电池上盖14、电池下盖16和多个侧板18包围电芯10，并用电池下盖18和电芯上盖12的侧板定位部24对侧板进行定位，与相关技术中采用PVC膜包覆电芯或者一体成型的保护壳相比，极大地提高了大容量锂电池电芯的防护效果，即便电池使用过程中由于使用环境恶劣，也不容易发生电芯10窜动，更不会因电芯外露而造成破损或者因为保护壳的设计不合理而对电芯造成挤压，可有效避免电芯与外界异常接触或受到挤压造成电芯内部正负极短路引起起火甚至爆炸。通过在电池上盖的下方，多个侧板的上端设置电芯上盖，一方面加强了对电芯10的防护，避免电芯10在壳体内大幅度窜动而发生磕碰，另一方面可避免外部的水汽经电池上盖、或电池上盖14与多个侧板之间的连接间隙进入壳体内部后直接对电芯10造成影响，电芯上盖12能够对水汽起到阻碍效果，有利于提高电芯的防水效果。通过对整个电池壳体的合理设计，提高电池的安全性能，有效避免外部的水汽进入壳体内部的同时可以更好地防止外部力量造成内部的电芯10受到不必要的挤压或损耗，使得电池能够适应不同的环境，提高电池的性价比。其中，多个侧板18可以单独加工成型，一方面方便生产加工，方便电池的组装，减小生产成本，另一方面在任意相邻的两个侧板的连接处设置第一密封件，可有效密封两者之间的连接间隙，确保电池壳体的防水性能，解决非一体成型防护壳结构的弊端。例如，侧板定位部24为定位槽，多个侧板18的部分边缘插设于电池下盖16的定位槽中，多个侧板18的部分边缘插设于电芯上盖12的定位槽中。再例如，侧板定位部24为定位凸出，多个侧板18的边缘上相对定位凸出的位置设有定位凹槽，定位凸出与定位凹槽相配合，定位凸出的个数为多 个。
在一些实施例中，如图1至图3、图5所示，基于任意相邻的两个侧板18的连接处设有第一密封件20的情况，任意相邻的两个侧板18中的一个侧板18的至少一个侧壁上具有向自身内部下沉的安装台186，第一密封件20设置在安装台186和与之相邻的侧板18之间。
在该实施例中，在任意相邻的两个侧板18的连接处设有第一密封件20的情况下，也即多个侧板18单独成型，设定相邻两个侧板18的其中一个侧板18的至少一个侧壁上具有向内沉的安装台186，一方面方便第一密封件20的设置，便于将第一密封件20准确、快速地涂覆或粘贴到指定位置，另一方面通过将第一密封件20设置在向内沉的安装台186上，而非直接涂覆或粘贴到侧板18的侧壁上，可对第一密封件20进行隐藏，避免第一密封件20直接经相邻两个侧板18之间的连接间隙外露而影响外观，甚至影响第一密封件20的密封效果及使用寿命。
另外，安装台186的设置也有利于侧板18的快速安装，只需对准安装台186进行连接即可，便于多个侧板18快速找准位置进行对接，提高组装效率。例如，在任意相邻的两个侧板18中，在其中一个侧板18上设有安装台186，而另一个侧板18挤压第一密封件20对接在安装台186上后，另一个侧板18的外观面与设有安装台186的侧板18的侧壁的外观面相平齐；或者另一个侧板18的至少一个侧壁上具有向自身外部凸出的凸出部，在该另一个侧板18对接在安装台186上后，该凸出部遮盖设有安装台186的侧板18的侧壁，可有效避免外部的水汽经连接间隙进入壳体内部。
当然，第一密封件20也可不设置在安装台186上，可以设置在任意相邻的两个侧板18中任一个侧板18的侧壁上，将另一个侧板18挤压第一密封件20而与该侧壁相连接；或者在其中一个侧板18的内壁面上开设凹槽，将第一密封件20设置在该凹槽内，而与其相邻的侧板18插设在该凹槽内，实现相邻两个侧板18之间的密封连接。第一密封件20可以设置在多个具体位置，只要满足设置在相邻两个侧板18之间的连接处即可，均符合本发明的技术构思。
在一些实施例中，如图1至图3所示，电池外壳还包括第一连接件22，第一连接件22穿过安装台186和与之相邻的侧板18，以夹紧第一密封件 20。
在该实施例中，通过采用第一连接件22穿过安装台186和与之相邻的侧板18，一方面提高了相邻两个侧板18之间的连接强度，另一方面可以夹紧第一密封件20，减小甚至消除相邻两个侧板18之间的连接间隙。能够起到有效抗击外界力量的冲击，对电芯10起到全方位的防护作用。
例如，第一连接件22为螺丝或螺栓，便于在将相邻两个侧板18组装在一起时，压紧两者之间的第一密封件20。当然，相邻两个侧板18之间也可以不采用第一连接件22连接，也可以采用例如卡扣、插槽与凸柱对接等方式进行连接，在此不一一列举。
在一些实施例中，如图1至图4所示，电池外壳还包括：第二密封件，设置在多个侧板18与电池下盖16的侧板定位部24处，以及多个侧板18与电芯上盖12的侧板定位部24处。
在该实施例中，通过在多个侧板18与电池下盖16的连接处，以及多个侧板18与电芯上盖12的连接处均设置第二密封件，在将整个壳体稳固的同时还可避免外部的水汽经多个侧板18整体与电池下盖16的连接处，以及多个侧板18整体与电芯上盖12的连接处进入壳体内部，造成电池损坏。其中，电芯上盖12设置在多个侧板18整体的上端，可盖设在多个侧板18的上端面，第二密封件夹设在多个侧板18的上端面与电芯上盖12的下端面之间；电芯上盖12也可位于多个侧板18整体的上端的内侧，第二密封件夹设在电芯上盖12的外侧面与多个侧板18上端的内侧面之间。同样地，在电池下盖16盖设在多个侧板18的下端面的情况下，第二密封件夹设在电池下盖16与多个侧板18的下端面之间；在电池下盖16位于多个侧板18整体下端的内侧的情况下，第二密封件夹设在电池下盖16的外侧面与多个侧板18的内侧面之间。
需要说明的是，本发明中的第一密封件20和第二密封件均为统称，设置在任意相邻的两个侧板18连接处的密封部件统称为第一密封件20，而设置在多个侧板18与电芯上盖12的连接处的密封部件，以及设置在多个侧板18与电池下盖16的连接处的密封部件统称为第二密封件。
在一些实施例中，第二密封件包括密封胶。
在该实施例中，具体介绍了第二密封件可为密封胶，当然也可以为硅胶圈 或橡胶圈等，可根据实际需要选择适当的密封部件，在此不一一列举。
在一些实施例中，如图10所示，在第二密封件包括密封胶的情况下，电池下盖16和电芯上盖12上均设有侧板定位部24，密封胶填充在侧板定位部24内，多个侧板18的上、下两端插设在侧板定位部24内。
在该实施例中，具体介绍了在第二密封件包括密封胶的情况下，可在电池下盖16和电芯上盖12上均开设有侧板定位部24，便于在注胶过程中，快速地将密封胶注入到准确位置。另外，通过侧板定位部24容纳密封胶，一方面可避免密封胶受压外溢而影响外观效果，另一方面在将多个侧板18的上、下两端分别插设在对应的电芯上盖12上的侧板定位部24内、电池下盖16上的侧板定位部24内的过程中，受到侧板定位部24的限制，密封胶可在小空间内充分形变填充，甚至填满插入多个侧板18后侧板定位部24内余下的空间，在完成对侧板18定位的同时还能有利于提高防水效果。
在一些实施例中，如图2至图4、图9至图11所示，电池下盖16和电芯上盖12上均设有安装孔26，多个侧板18相对于安装孔26的位置设有安装部190；电池外壳还包括第二连接件28，第二连接件28穿过安装孔26伸入安装部190内部。
在该实施例中，通过在电池下盖16和电芯上盖12上均设有安装孔26，通过第二连接件28穿过安装孔26伸入到多个侧板18上，例如具体伸入到多个侧板18的安装部190上，可将多个侧板18与电池下盖16之间，以及多个侧板18与电芯上盖12之间牢固连接。例如，第二连接件28为螺钉或螺栓。
在一些实施例中，如图4、图5、图10所示，电池下盖16和电芯上盖12上的侧板定位部24均延伸至安装孔26的孔周。多个侧板18上对应于安装孔26的部位向外凸出，以在其内侧形成安装腔188，安装部190位于安装腔188内。
在该实施例中，通过将电池下盖16上的侧板定位部24延伸至电池下盖16上的安装孔26的孔周，将电芯上盖12上的侧板定位部24延伸至电芯上盖12上的安装孔26的孔周，使得在向侧板定位部24内充填密封胶时，密封胶可以设置在安装孔26的孔周。通过将多个侧板18上对应于安装孔26的部位向外凸出以在其内侧形成安装腔188，并将安装部190设置在安装腔188 内，一方面由于侧板定位部24延伸至安装孔26的孔周，进而多个侧板18向外凸出的部位可与涂覆在安装孔26孔周的密封胶进行贴合，可确保多个侧板18在周向上均能够与密封胶进行贴合，提高密封效果；另一方面多个侧板18局部向外凸出，提高了多个侧板18的结构强度，有利于对内部电芯10进行安全防护；再一方面由于安装部190设置在安装腔188内，可提高电池的外观效果。例如，侧板定位部24分布在电池下盖16的边沿处；电池下盖16上的多个安装孔26与电芯上盖12上的多个安装孔26一一对应。
在一些实施例中，如图4和图5所示，电池下盖16的边沿处设有外凸的安装耳162，安装孔26设置在安装耳162上；电池外壳还包括安装脚30，安装脚30包覆在安装耳162的外侧，安装脚30上设有供第二连接件28伸入的避让孔。进一步地，安装脚30的一端具有弯折边302，弯折边302包覆安装耳162的外包边164，在多个侧板18与电池下盖16的侧板定位部24配合连接的情况下，弯折边302夹设在安装耳162的外包边164与多个侧板18之间。
在该实施例中，可在电池下盖16的边沿处设置外凸的安装耳162，安装耳162优选与电池下盖16一体成型，并采用安装脚30包覆安装耳162，可有效防止壳体的边角部位发生磕碰而损坏。具体地，安装脚30至少包覆安装耳162的下端和外侧，并将安装脚30一端的弯折边302插设在多个侧板18与安装耳162的外包边164之间，安装脚30可以起到提高多个侧板18与电池下盖16的连接强度的作用，在电池受到外部力量冲击或撞击时，能够起到有效的防护。
在一些实施例中，如图4、图8至图11所示，安装耳162包括主体部和外包边164，安装孔26设置在主体部上，侧板定位部24延伸至主体部，外包边164包覆在主体部的外侧，外包边164的一端从主体部向所述电芯上盖12的方向延伸，外包边164的另一端从主体部向远离电芯上盖12的方向延伸，在第二连接件28安装在电池下盖16上的情况下，外包边164的下端面低于第二连接件28的下端面。
在该实施例中，由于外包边164包覆在主体部的外侧，而侧板定位部24延伸至主体部上，进而在多个侧板18沿侧板定位部24的槽壁插设在延伸至主 体部上的侧板定位部24上的情况下，外包边164与多个侧板18之间会留有一定间隙，该间隙可为侧板定位部24的槽壁的厚度，进而方便安装脚30的弯折边302插设在该间隙内。另外，通过设置外包边164的另一端从主体部向远离电芯上盖12的方向延伸，且在第二连接件28安装在电池下盖16上的情况下，外包边164的下端面低于第二连接件28的下端面，可有效避免第二连接件28安装后外露于电池下盖16，而极易与周围部件发生磕碰。例如，安装脚30的另一端具有包底边，包底边包覆外包边164的下端面。
在一些实施例中，如图4所示，电池外壳还包括防水圈32，第二连接件28穿过防水圈32伸入安装孔26内，以将防水圈32压设在电池下盖16上。
在该实施例中，通过设置防水圈32，将第二连接件28穿过防水圈32伸入安装孔26内，并将防水圈32压设在电池下盖16上，由于防水圈32的两端分别与电池下盖16、第二连接件28紧密贴合，可有效避免外部的水汽经第二连接件28与电池下盖16之间的连接间隙进入壳体内部。防水圈32可呈圆环形，也可呈方环形，只要其在电池下盖16上的投影围设在安装孔26的孔周即可。
当然，防水圈32也可以设置在电芯上盖12的安装孔26处，使得第二连接件28穿过防水圈32伸入安装孔26内，以将防水圈32压设在电芯上盖12上。
在一些实施例中，如图4所示，电池外壳还包括压板34，压板34套设在第二连接件28上，第二连接件28依次穿过压板34、防水圈32伸入安装孔26内。
在该实施例中，在第二连接件28不足以挤压到防水圈32的情况下，还可以设置压板34，第二连接件28通过推动压板34来间接挤压防水圈32。
在一些实施例中，如图4所示，电池下盖16的下表面设有环形凸出166，环形凸出166在电池下盖16的下表面上的投影围设在安装孔26的外周，防水圈32设置在环形凸出166的内侧。
在该实施例中，通过在电池下盖16的下表面设置环形凸出166，并保证其在电池下盖16上的投影围设在安装孔26的孔周，将防水圈32设置在环形凸出166内，一方面方便防水圈32的快速安装，另一方面有利于防水圈32 受压时，在环形凸出166的挤压作用下，能紧密地与电池下盖16相贴合，提高防水效果。该环形凸出166可为圆环形凸出166，也可为方环形凸出166，优选与防水圈32的形状相适配。
在一些实施例中，如图2和图3所示，电池外壳还包括：第三密封件36，设置在电池上盖14与电芯上盖12的连接处。
在该实施例中，还可在电池上盖14与电芯上盖12的连接处设置第三密封件36，进而可有效避免外部的水汽经两者之间的连接缝隙进入壳体内部。电池上盖14可直接与电芯上盖12连接，从而间接与多个侧板18相连接；电池上盖14也可直接与多个侧板18相连接，并在内侧进一步防护，在电池上盖14与电芯上盖12之间设有第三密封件36，确保密封效果。
在一些实施例中，第三密封件36包括软质胶、硬质胶、硅胶圈中的一种或多种。
在该实施例中，第三密封件36可仅采用软质胶或硬质胶或硅胶圈，也可采用软质胶和硬质胶相结合，或硬质胶与硅胶圈相结合，或软质胶与硅胶圈相结合，多种组合方式均可以。
在一些实施例中，如图1至图3所示，电池上盖14罩设在电芯上盖12上，第三密封件36设置在电池上盖14的内侧面与电芯上盖12的外侧面之间。
在该实施例中，在电池上盖14罩设在电芯上盖12上的情况下，在电池上盖14的内侧面与电芯上盖12的外侧面之间设有第三密封件36，可有效避免外部的水汽经电池上盖14与电芯上盖12之间的间隙进入壳体内部。
在一些实施例中，电池上盖14的内侧面或电芯上盖12的外侧面设有容纳槽，第三密封件36设置在容纳槽内。
在一些实施例中，电池还包括：连接器，连接器设置在电池上盖14内，并与电芯10电连接；以及电池外壳还包括密封圈，用于套设在连接器的外围。
在该实施例中，电池还具有连接器，通过连接器与外界电连接。其中，连接器设置在电池上盖14内，并与电芯10电连接。优选连接器通过电芯上盖12上的通孔与电芯10电连接，在周向上多个侧板18的上端各处均与电芯 上盖12相连接，确保防护效果。当然，多个侧板18的上端的局部可与电芯上盖12留有间隙，连接器通过该间隙与电芯10电连接。通过在连接器的外围套设密封圈，可有效避免在外部力量撞击到壳体时直接对电芯造成冲击，另外也可以避免由于壳体本身对电芯造成挤压使得电芯受力不均匀而产生短路引起起火或爆炸。另外还可以避免外部的水汽经连接器的安装间隙进入壳体内部，起到一定的防水作用。
在一些实施例中，如图1至图7所示，基于任意相邻的两个侧板18的连接处设有第一密封件20的情况，多个侧板18包括两个相对设置的第一侧板182和两个相对设置的第二侧板184，两个第一侧板182和两个第二侧板184围成桶状结构，第一侧板182的板面积小于第二侧板184的板面积，第一侧板182拉伸成型，第二侧板184冲压成型。
在该实施例中，具体介绍了多个侧板18包括四个侧板18，分别为两个相对设置的第一侧板182和两个相对设置的第二侧板184，四个侧板18围成桶状结构。以板面积较大的两个侧板18设为正、反面侧板18，板面积较小的两个侧板18设为两侧的侧板18。通过设置两侧的侧板18拉伸成型，便于在电芯10放置在壳体内后，与电芯10之间留有极小的缝隙，有利于抗击外部的冲击，还能够使电芯10通过两侧的侧板18进行散热。通过设置正、反面的侧板18冲压成型，方便加工，有利于减轻侧板18的重量。当然，多个侧板18的个数也可以为六个，八个等，可依据电芯10的形状进行相应的设定，多个侧板18也可以均为拉伸成型或冲压成型，在此不一一列举。
在一些实施例中，第一密封件20包括密封胶。当然，在另一实施例中，第一密封件20包括双面胶纸。
在一些实施例中，侧板18为轻金属板或非金属板。
在该实施例中，侧板18优选为轻金属板，质量轻，防水效果好，且结构强度高。优选侧板18为铝板或镁板或镁铝合金板等。侧板18也可以为非金属板，只要具有类似的刚度和强度，能够承受一定的冲击，而且质量一般也较轻，如具有防水功能的塑料板、陶瓷板等。
本发明的第二方面的实施例提供的电池组件，因包括第一方面实施例中任 一项的电池外壳，因而具有上述任一实施例所具有的一切有益技术效果，在此不再赘述。
如图12所述，本发明第三方面的实施例提供的植保无人机1000，包括：机身以及如第二方面实施例的电池组件，电池组件设于机身上。

本发明的第四方面还提供电池的组装方法，在本实施例中，该方法第一步需要将电芯设置在电池下盖的中部位置。在将电池电芯固定好后，将电池外壳的侧板按顺序装配到电池下盖的侧板定位部上。并需要在任意相邻的两个侧板18的连接处设有第一密封件，装配后的多个侧板围设于电芯的四周形成一密封筒状结构。再将电芯上盖通过电芯上盖的侧板定位部定位设置在多个侧板18的上端。完成后，将电池上盖盖设于所述电芯上盖的上方，以将所述电芯密封于所述电池外壳内。
进一步地，在另一实施例中，侧板18的安装顺序为先先安装两个相对设置的第一侧板18，再安装两个相对设置的第二侧板18。其中第一侧板18的板面积小于所第二面板的板面积，两个第一侧板18和两个第二侧板18围成桶状结构。可以理解的是，在其他实施例中，也可以先安装两个第二侧板18，再安装两个第一侧板18，又或者第一侧板18和第二侧板18有多个，安装顺序为间隔安装，由于存在多种顺序，在此不做限定。
进一步地，在一些实施例中，可使用第一连接件，例如螺钉或螺栓穿过一个侧板上安装台和与之相邻的侧板，以夹紧第一密封件。例如，第一侧板的两侧设有安装台，螺栓依次穿过第二侧板伸入第一侧板的安装台内。
进一步地，在一些实施例中，可向电池下盖的侧板定位部内和电芯上盖的侧板定位部内填充密封胶，来进一步密封多个侧板与电池下盖和电芯上盖的连接处。
