请一并参阅图1-图3，本发明实施方式的电池壳体100用于电池102，电池壳体100包括外壳10和减震元件20。外壳10形成有多个边部11和多 个角部12。边部11连接角部12。减震元件20包裹边部11和角部12。
本发明的电池壳体100，减震元件20可以在外壳10的边部11和角部12受到碰撞时减弱外壳10所受的冲击力，从而提高了收容在外壳10内的电池102的抗震能力。
可以理解，电池102的收容在外壳10内，电池102放电时可以为无人飞行器提供电能。边部11例如为外壳10的边缘位置，角部12例如为外壳10的角部位置。
外壳10的边部11和角部12最容易受到碰撞，从而导致外壳10变形，则可能导致电池102被挤压而无法正常使用，因此，在外壳10的边部11和角部12设置减震元件20可以减弱电芯104收到的冲击力，也可以防止外壳10变形而挤压电芯104，以保证电池102能够正常使用。
需要说明的是，边部11可以为壳体10的两个面相交处呈尖锐的棱边，也可以为棱边进行钝化处理后连接两个面的第一连接部。角部12可以为壳体10的多个面相交处呈尖锐的棱角，也可以为棱角进行倒钝处理后连接多个面的第二连接部。
具体地，减震元件20的材料例如为橡胶和/或泡棉。橡胶和泡棉具有较好的减震能力，因此，减震元件20由橡胶和/或泡棉制成可以提高电池102的抗震能力。
另外，泡棉的重量较轻，可以降低电池102的重量，从而降低无人飞行器的重量。
泡棉例如可以是EVA(Ethylene Vinyl Acetate)泡棉、PU(Poly Urethane)泡棉或EPP(Expanded Poly Propylene)泡棉等泡棉。
在某些实施方式中，外壳10包括底壳13、上盖14和多个侧板15。上盖14与底壳13相对设置。多个侧板15连接底壳13及上盖14。多个侧板15、底壳13及上盖14共同限定边部11和角部12。
具体地，底壳13、上盖14和多个侧板15连接形成外壳10，并使外壳 10大致呈长方体，从而使得外壳10形成边部11和角部12。底壳13的材料例如为橡胶或泡棉，从而使得电池102在放置的时候可以得到缓冲，进而可以进一步提高电池102的抗震能力。
多个侧板15可以一体成型制成，也可以由多个侧板15独立成型后连接制成。本实施方式中，一个侧板15由一个板材折弯而成。
多个侧板15的材料例如为金属和/或碳纤维。由于金属和碳纤维具有较高的强度，这样可以防止外壳10变形，从而避免外壳10内的电芯104受到挤压。
另外，当多个侧板15的材料为金属时，多个侧板15可以将由电芯104产生的热量快递地传递到电池102外的空气中，从而减低电芯104温度，保证电池102能够正常使用。
在一个例子中，多个侧板15的材料为铝合金。一方面，因为铝合金的密度较小，由此可减轻电池102的重量。另一方面，铝合金还具有硬度较小、容易成型的特点，并且成本较低，有利于多个侧板15进行批量生产。
再有，由于铝合金的耐腐蚀性较好，由铝合金材料制成的侧板15可提高电池102的寿命。当然，侧板15的材料也可以为铝或镁合金等其他金属。
在某些实施方式中，底壳13包括底板131及侧壁132。侧壁132自底板131的周缘向上延伸。多个侧板15与侧壁132连接。
侧壁132可以增大底壳13与侧板15的连接面积，以保证侧板15与底壳13牢固地连接在一起。
在某些实施方式中，减震元件20包括包边部21和两个包角部22。两个包角部22分别连接在包边部21相背的两端。包边部21覆盖边部11，每一个包角部22覆盖一个对应的角部12。
具体地，包边部21包裹多个侧板15所形成的边部11，其中一个包角部22包裹多个侧板15与上盖14形成的角部12，另一个包角部22包裹多个侧板15与底壳13形成的角部12。
包边部21和两个包角部22可以为一体成型结构，例如，当减震元件20由橡胶制成时，减震元件20可以由熔融的橡胶倒入至模具中而成型。
减震元件20的数量为两个，两个减震元件20设置在外壳10相背的两侧，并分别包裹外壳10的相对的边部11和角部12。
为了方便用户拿取电池102，在某些实施方式中，包边部21的外表面形成有多个凹槽211。多个凹槽211还可以增加拿取电池102时的摩擦力，防止电池102在转运移动的过程中脱落。
本实施方式中，多个凹槽211沿边部11的长度方向排布，从而增大凹槽211的分布面积。
在某些实施方式中，包边部21开设有通孔212，外壳10通过通孔212暴露。
如此，通孔212不仅使得减震元件20的材料较少，以节约减震元件20的制造成本，还可以增大侧板15与空气的接触面积，从而可以提高电池102的散热速率，有利于电池102正常工作。
在某些实施方式中，电池壳体100还包括设置在外壳10及减震元件20之间，且包裹边部11的防护件112，减震元件20与防护件112配合连接。
具体地，本实施方式中，防护件112包裹侧板15所形成的边部11。在其他实施方式中，防护件112可包裹其他边部11，例如底壳13形成的边部11。
如此，防护件112可进一步提高电池102的抗震能力。防护元件例如呈直角型，从而可以较好地包裹外壳10的边部11。防护元件可以采用强度和刚度较好的材料制成，从而较好地防护外壳10的边部11。例如，防护元件的材料例如铝合金、镁合金或不锈钢等金属材料，或者碳纤维等非金属材料。
本发明实施方式的电池组件101包括电池102和以上任一实施方式的电池壳体100，电池102收容在外壳10中。
本发明的电池组件101，减震元件20可以在外壳10的边部11和角部 12受到碰撞时减弱外壳10所受的冲击力，从而提高了收容在外壳10内的电池102抗震能力。
在某些实施方式中，电池102包括串联连接的多个电芯104。电芯104例如为锂电芯，从而可以存储大量的电量，并且使得电池102的体积较小。
电池组件101可以应用在无人飞行器上，尤其是农业无人飞行器，从而为无人飞行器提供动力。另外，由于农业无人飞行器的使用环境较为恶劣，减震元件20可减弱外壳10所受的冲击力，保证电池102能够正常地运行。
无人飞行器例如为旋翼无人飞行器，无人飞行器在飞行的过程中可以完成相应的任务，例如侦查、喷药、勘测等。
具体地，无人机飞行器包括机体和动力组件。动力组件与机体连接。动力组件例如包括无人飞行器的电机。电池组件101装设于机体中，以对无人飞行器供电。
在某些实施方式中，电池组件101还包括设置在外壳10上的提手30。如此，提手30方便用户拿取电池102。可以理解，电池102正常放置时，上盖14朝上，提手30固定在上盖14上，提手30与上盖14之间形成有抓取空间31，以便于用户抓握提手30而将电池102提起。
较佳地，提手30的材料为塑料，从而可以提高提手30的抗冲击能力，进而可以提高电池102的抗震能力。
在某些实施方式中，提手30内装有电路板106，电路板106用于管理电池102的工作状态、电池102的电量均衡和电池102的电量中的一种或多种。
电路板106收容于提手30内，使得电池102的结构更加紧凑，有利于电池102小型化。电路板106可以监测管理电池102的电量、电压、电流和充放电过程等状态，使得电池102可以被合理地使用，以提高电池102的寿命和防止无人飞行器出现意外。
电路板106还可以实现电芯104的电量均衡，以保证电芯104在使用过 程中的稳定性，提高电池102的寿命。电路板106还可以管理电池102的电量，例如，当电池102的电量低于预定值时，电路板106可以控制电池102停止放电。
在某些实施方式中，提手30包括第一壳32和第二壳33，第一壳32设置在上盖14上，第二壳33与第一壳32能够拆卸地配合连接并共同限定容置空间30a，电路板106收容在容置空间30a内。
如此，在安装电池组件101的电路板106时，可先将第二壳33从第一壳32上拆卸下来，然后将电路板106装至第一壳32上，最后将第二壳33安装至第一壳32上，并覆盖电路板106，从而完成电路板106的安装。由此，第一壳32与第二壳33能够拆卸地连接使得电池102的电路板106安装方便。
具体地，第二壳33上设置有卡勾331，可以理解，第一壳32上可设置有与卡勾331相配的卡槽，第二壳33通过卡勾331与卡槽配合从而可以安装在第一壳32上，并且使得第二壳33与第一壳32拆装方便，方便电池102的电路板106的维护和有利于提高电池102装配效率。
在某些实施方式中，电池组件101包括设置在提手30上的开关108，开关108用于控制电池102放电。例如，当开关108闭合时，电池102可以向无人飞行器输出电量，当开关108断开时，电池102停止输出电量。
本实施方式中，电池组件101包括设置在提手30上的指示灯110，指示灯110用于显示电池102的电量和/或工作状态。指示灯110方便用户及时获取电池102的电量信息和工作状态，方便用户对电池102管理。例如，当指示灯110发亮时，电池102可向无人飞行器输出电能，当指示灯110熄灭时，电池102停止向无人飞行器输出电能。
本实施方式中，指示灯110的数量为4个。发光的指示灯110的数量与电池102的电量成正相关的比例关系。
例如，当电池102的电量为100％时，那么4个指示灯110全部发光。 当电池102的电量为50％时，则只有2个指示灯110发光。用户可以根据指示灯110的发光的数量判断电池102的剩余电量。
可以理解，在其他实施方式中，指示灯110可根据实际需求而具体设定，例如指示灯的数量为6个或其它数量。
开关108和指示灯110均可与电路板106电性连接。
在某些实施方式中，电池组件101包括用于包裹电池102的连接线40的柔性保护件50，柔性保护件50连接在外壳10上。
柔性保护件50可以防止连接线40摩擦而损坏，保证电池102可以为无人飞行器提供电能。可以理解，连接线40与电池102的电芯104连接。
具体地，柔性保护件50可由橡胶制成，以使得柔性保护件50可以具备相应的柔性能力。柔性保护件50呈条形，一端穿过提手30上的插口电连接至电量板106上，另一端可以形成插接口以方便与无人飞行器连接。柔性保护件50可以弯曲一定的角度。
在一个例子中，柔性保护件50的数量为三个，连接线40的线束安装在柔性保护件50内。其中两个柔性保护件50内可以安装电池102的动力线，动力线可以为无人飞行器提供相应的电能。另一个柔性保护件50内可以安装电池102的均衡线，均衡线可以对电池102的状态进行监测和使电池102的电量均衡。
需要说明的是，本实施方式的电池组件101其他未展开的部分，可参考以上实施方式的电池壳体100的相同或相似的部分，在此不再赘述。
在本说明书的描述中，参考术语“一个实施方式”、“某些实施方式”、“示意性实施方式”、“示例”、“具体示例”、或“一些示例”等的描述意指结合所述实施方式或示例描述的具体特征、结构、材料或者特点包含于本发明的至少一个实施方式或示例中。在本说明书中，对上述术语的示意性表述不一定指的是相同的实施方式或示例。而且，描述的具体特征、结构、材料或者特点可以在任何的一个或多个实施方式或示例中以合适的方式结合。
此外，术语“第一”、“第二”仅用于描述目的，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。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括至少一个该特征。在本发明的描述中，“多个”的含义是至少两个，例如两个，三个等，除非另有明确具体的限定。
尽管已经示出和描述了本发明的实施方式，本领域的普通技术人员可以理解：在不脱离本发明的原理和宗旨的情况下可以对这些实施方式进行多种变化、修改、替换和变型，本发明的范围由权利要求及其等同物限定。
