这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本发明相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本发明的一些方面相一致的装置和方法的例子。
在本发明使用的术语是仅仅出于描述特定实施例的目的，而非旨在限制本发明。在本发明和所附权利要求书中所使用的单数形式的“一种”、“所述”和“该”也旨在包括多数形式，除非上下文清楚地表示其他含义。还应当理解，本文中使用的术语“和/或”是指并包含一个或多个相关联的列出 项目的任何或所有可能组合。
下面结合附图，对本发明的电机端盖、电机、动力装置及飞行器进行详细说明。在不冲突的情况下，下述的实施例及实施方式中的特征可以相互组合。
参见图1和图2所示，本发明实施例提供一种电机端盖1，适用于体积小、结构紧凑的电机结构。所述电机端盖1具有圆形外形结构，所述电机端盖1包括：盖底10、围设于所述盖底10外周的外筒20、以及设置于所述盖底10上用于连接电机的转子的轴套体30，轴套体310的中部开设有轴孔310，电机的转子的转轴可以穿设在所述轴孔310中，进而当电机的转子转动时能够带动电机端盖1一同转动。所述外筒20和所述轴套体30之间设有多组间隔设置的散热组件40，每一组所述散热组件40包括多个间隔设置的肋片410，所述肋片410相对于所述轴套体30的径向朝向相同方向(即朝同一方向)呈倾斜设置。在本实施例中，所述盖底10、所述外筒20以及所述轴套体30为一体成型。
由上述实施例可知，本发明的电机端盖1，通过将散热组件40的肋片410相对于轴套体30的径向朝向相同方向呈倾斜设置在外筒20和轴套体30之间，当电机端盖1随电机的转子一同转动时，肋片410的转动能够加速电机内的空气流动，对转子带动的气流起到导流的作用，能够让热量有序的从中心发散到外围，从而提高电机的散热效率。
参见图2所示，在本发明一实施方式中，所述多个散热组件40形成于所述盖底10上，并沿所述外筒20的圆周呈辐射状均匀布设于所述外筒20和所述轴套体30之间，当电机端盖1随电机的转子一同转动时，肋片410的转动能够使电机内的空气流动更加均匀，并且散热组件40可以对外筒20起到支撑作用，进而增强电机端盖1的结构强度。可选择的，设置于外筒20和轴套体30之间散热组件40可在其两端分别间隔且均不与外筒20和轴套体30相接触，而由于散热组件40的倾斜设置仍然能够对流动的 空气起到导流的作用。
进一步地，所述盖底10上设有多个散热槽110，每一个所述散热槽110与相邻的两组所述散热组件40之间的间隔相连通。当电机端盖1随电机的转子一同转动使得肋片410加速空气流动时，所述散热槽110能使空气快速排出电机，从而进一步提高电机的散热效率。
参见图2所示，在本发明一实施方式中，每一组所述散热组件40的每一个所述肋片410相对于所述轴套体30的径向的倾斜方向(图2中所示为沿圆周的逆时针方向倾斜)均相同。进一步的，每一组所述散热组件40的每一个所述肋片410相对于所述轴套体30的径向的倾斜角度(图2中所示为角α)均相同。在本实施例中，散热组件40的数量为三组，每一组所述散热组件40包括3个肋片410，易于对电机端盖1加工成型并能增强电机端盖1的结构强度。
可选地，所述每一组散热组件40中的肋片410的一端汇聚并连接于所述轴套体30，所述肋片410的另一端自所述轴套体30向外发散延伸。在本实施例中，每一组所述散热组件40均包括安装部420，每一组散热组件40的每一个肋片410的一端均汇聚设置于所述安装部420上，所述肋片410的另一端自所述轴套体30向外发散延伸并与所述外筒20连接，所述安装部420与所述轴套体30连接，进而将所述散热组件40装设在所述外筒20和所述轴套体30之间。所述安装部420能够增强散热组件40的结构强度。而直接连接于所述外筒20和所述轴套体30之间的散热组件40能够增强所述电机端盖1整体的结构强度。可选地，所述散热组件40的安装部420和各肋片410为一体成型。
所述肋片410沿所述轴套体30的高度方向的高度a为3.2mm±2mm，保证了肋片410转动时与空气有足够大的接触面积，从而有效加速空气流动速度。
参见图3所示，所述肋片410相对于所述轴套体30的径向的夹角α为13°±10°，即所述肋片410与所述肋片410相对于所述外筒20的圆周方向的夹角θ为77°±10°，当电机端盖1随电机的转子一同转动时，肋片410的转动能够使空气达到较快的流动速度，使电机达到较高的散热效率。其中，所述圆周方向指的是外筒20在肋片410的延伸线与外筒20相交位置的切线方向。
所述散热组件40的多个所述肋片410相互倾斜设置，相邻的两个所述肋片410之间的夹角β为16°±10°，当电机端盖1随电机的转子一同转动时，肋片410的转动能够使空气达到更快的流动速度，以进一步提高电机的散热效率。
参见图1、图4以及图5所示，在本发明一实施方式中，所述外筒20上形成有散热狭缝，当电机端盖1随电机的转子一同转动使得肋片410加速空气流动时，当气流被肋片410引流到外筒20上时，空气能够从所述散热狭缝中排放至电机外部以带走电机产生的热量，从而进一步提高电机的散热效率。
在图4所示的例子中，所述散热狭缝为环形孔210，即相当于所述环形孔210将所述外筒20分隔为上部体201和下部体202，上部体201和下部体202之间通过延伸至所述外筒20上的散热组件40相互连接，也可以通过一定数量的连接件203相互连接。所述散热狭缝采用环形孔210，能够形成最大面积的散热通道，当电机端盖1随电机的转子一同转动时，可以使电机内的空气以最快的速地排出电机，使电机达到最大的散热效率。
在图5所示的例子中，所述散热狭缝包括多个散热通孔211，所述多个散热通孔211沿圆周均匀布设于所述外筒20上。所述散热狭缝采用多个散热通孔211的方式，不仅能够形成较大面积的散热通道，当电机端盖1随电机的转子一同转动时，使电机内的空气以较快的速地排出电机，使电机达到较大的散热效率，而且相邻的两个散热通孔211之间的连接部分 同样是沿圆周均匀布设于所述外筒20，也能够保证外筒20的结构强度。可选地，所述散热通孔211可以包括但不仅限于平行四边形孔、圆形孔或椭圆形孔。
在本发明一实施方式中，所述外筒20上还设有用于与电机的转子连接的环状连接部230及沿圆周均匀布设于所述环状连接部230的多个导向部220，所述导向部220沿所述轴套体30的高度方向凸出于所述外筒20的端部。通常，电机的转子内会沿圆周设置有一圈插接部，所述导向部220用于在电机端盖1通过所述外筒20的环状连接部230装设到电机的转子的插接部时，导正环状连接部230插入所述插接部的方向，更便于将电机端盖1拆装到电机的转子上。
参见图6所示，本发明实施例还提供一种电机2，包括：定子、转动连接于所述定子的转子3、以及电机端盖1，所述电机端盖1装设于所述转子3上。在本实施例中，所述肋片410的倾斜朝向与电机2的转子3转动方向同向。需要说明的是，上述实施例和实施方式关于所述电机端盖1的描述同样适用于本发明的电机。
在本发明一实施方式中，所述转子3包括转轴4，所述电机端盖1的轴套体30包括轴孔310，所述转轴4穿设于所述轴孔310并部分凸出于所述电机端盖1。
参见下表1所示，其中，电机A是普通的传统开放式电机及其电子调速器在不同输入功率下的工作温度相对于环境温度的差值(简称相对环境温升)得到的测试数据，电机B和电机C分别是采用本发明的电机及其电子调速器在不同输入功率下的工作温度相对于环境温度的差值(简称相对环境温升)得到的两组测试数据。
通过对比两组相对环境温升数据，可以直观地得出：在输入功率相等的情况下，对电机或其电子调速器的相同部位进行测温，本发明的电机 2及其电子调速器相对环境温升值明显低于普通的传统开放式电机其电子调速器相对环境温升值。因此可以看出，本发明的电机2的散热效果相对于传统的开放式电机散热效果更好。
同时，在输入功率相对较大时，本发明的电机2及其电子调速器相对环境温升值与传统开放式电机其电子调速器相对环境温升值之间的差值亦相对较大，由此可见，本发明的电机2的散热效率相对于传统的开放式电机散热效率更高。
因此，本发明的电机2的散热性能可以比其他形式的风扇温升提高至少15％，同时结构刚度上也有一定的加强。
