Description

智能电池保护板、智能电池及可移动平台 技术领域
本发明涉及一种智能电池保护板、使用该智能电池保护板的智能电池及可移动平台。
背景技术
目前无人飞行器主要采用智能电池作为其电源，因为智能电池的体积比容量较低，因此造成了无人飞行器的续航时间较短。
目前智能电池通常有保护板、极耳板和电芯构成，其中极耳板和保护板通过连接器和电源线进行连接；电芯的正极耳和负极耳会穿过极耳板专门设置的通孔后再进行弯针并与极耳板焊接固定，需要单独提供极耳板。此外，保护板和极耳板之间留有空隙，会占据智能电池的容量空间，从而降低了智能电池的体积比容量。此外，连接线和电源线不仅增加了物料成本及组装成本，还降低了智能电池的工作稳定性。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
需要说明的是，当组件被称为“固定于”另一个组件，它可以直接在另一个组件上或者也可以存在居中的组件。当一个组件被认为是“连接”另一个组件，它可以是直接连接到另一个组件或者可能同时存在居中组件。当一个组件被认为是“设置于”另一个组件，它可以是直接设置在另一个组件上或者可能同时存在居中组件。
除非另有定义，本文所使用的所有的技术和科学术语与属于本发明的技术领域的技术人员通常理解的含义相同。本文中在本发明的说明书中所使用的术语只是为了描述具体的实施例的目的，不是旨在于限制本发明。本文所使用的术语“及/或”包括一个或多个相关的所列项目的任意的和所有的组合。
在实现本发明的过程中，发明人发现了如下问题：
目前可移动平台的工作时间通常较短，一个重要原因是因为电池的容量较低，即电池的续航能力较差。通常智能电池包括保护板、转接板(或称极耳板)和多个电芯组成。因为多个电芯需要根据产品的需要堆叠在一起，并且多个所述电芯延伸出的正极耳和负极耳焊接在同一块极耳板上。所述极耳板再通过连接器、电源线与保护板连接，从而形成完整的智能电池。
传统的智能电池需要正极耳和负极耳穿过极耳板，然后弯折与焊盘压接后再进行焊接，导致极耳板没有多余的面积布置电路，因此必须通过连接线与保护板连接。此外，极耳板与保护板之间存在空隙，这样浪费空间，不得不减小电芯的体积，从而会占据智能电池的容量空间，导致智能电池容量降低。再者，连接线和电源线增加物料成本、组装成本，并且导致了智能电池的可靠性降低。
本发明实施例提供的智能电池采用正极耳和负极耳与保护板的底面焊 接，从而使所述保护板的顶面具有有效面积用于布置电路。这样就不再需要极耳板以及与之配套的连接线等，同时提高了电连接的可靠性。同时，具有该智能电池的可移动平台具有更长的持续工作时间及更稳定的使用状态。下面，通过具体实施例，对智能电池及具有该智能电池的可移动平台进行详细说明。其中所述可移动平台可以为无人飞行器或者无人车等。所述可移动平台包括机身、动力系统以及所述智能电池，其中，所述机身设有电池仓，所述电池仓用于收容所述智能电池。所述智能电池收容于所述电池仓内，并且所述智能电池与所述动力系统电连接并为所述动力系统供电。
