请参考图1,本申请一实施例提供一种外转子轮毂电机10。外转子轮毂电机10包括轮毂外壳100、外转子(未示出)、内定子(未示出)。外转子和内定子均设置在轮毂外壳100内部。轮毂外壳100与外转子固定连接并随外转子同步旋转。轮毂外壳100可以是下面的实施例中任一项实施例中的轮毂外壳100。Please refer to FIG. 1 , an embodiment of the present application provides an outer
请结合图1至图3,本申请一实施例提供一种轮毂外壳100。轮毂外壳100包括位于外转子的径向外侧的轮毂圈110。轮毂圈110上设有至少一个沿其径向贯通的排水通孔111。排水通孔111内设置有至少一个弹性结构120。每个弹性结构120包括至少一个弹性件121,弹性件121的一端为固定端1211并与排水通孔111的孔壁连接,另一端为自由端1212。弹性件121具有闭合状态和打开状态。弹性件121在闭合状态时,弹性结构120的形态能使得排水通孔111阻塞;弹性件121在打开状态时,弹性结构120的形态能使得排水通孔111流通。弹性件121在受到沿轮毂圈110的径向向外的作用力时能从闭合状态切换至打开状态;在撤去沿轮毂圈110的径向向外的作用力时,弹性件121能通过自身的弹性恢复力而从打开状态切换至闭合状态。Please refer to FIG. 1 to FIG. 3 , an embodiment of the present application provides a
上述的轮毂外壳100,由于弹性件121的一端为固定端1211并与排水通孔111的孔壁连接,另一端为自由端1212,因此,弹性件121在受到外力作用从而产生弹性形变时,其自由端1212产生移位,从而能使得弹性结构120在打开状态和闭合状态之间切换。若外转子轮毂电机10内进水,外转子轮毂电机10运行时,轮毂外壳100随外转子同步旋转,水在离心力作用下撞击弹性件121,使得弹性件121受到沿轮毂圈110的径向向外的撞击力,同时在弹性件121自身的离心力作用下,弹性件121从闭合状态切换至打开状态,从而水从排水通孔111排出外转子轮毂电机10。外转子轮毂电机10停止运行时,弹性件121未受到沿轮毂圈110的径向向外的作用力,处于闭合状态,从而弹性结构120使得外转子轮毂电机10内部与外界环境中的水隔离,进而能防止外转子轮毂电机10进水。In the
请参考图2至图5,在一些实施例中,每个弹性结构120包括沿排水通孔111的周向依次排列的至少两个弹性件121。每个弹性结构120中弹性件121的数量例如是两个、三个、四个、五个、六个等。Please refer to FIG. 2 to FIG. 5 , in some embodiments, each
弹性结构120中所述至少两个弹性件121均处于闭合状态时,所述至少两个弹性件121的自由端1212向排水通孔111的中心合拢,且相邻的弹性件121之间密封配合,从而使得排水通孔111阻塞。弹性结构120中所述至少两个弹性件121从闭合状态切换至打开状态时,所述至少两个弹性件121的自由端1212从排水通孔111的中心向孔壁方向移位,从而使得排水通孔111流通。When the at least two
在其他实施例中,弹性结构可以包括一个弹性件。弹性件在闭合状态时,弹性件的自由端与排水通孔的孔壁密封配合,从而能阻塞排水通孔。弹性件从闭合状态切换至打开状态时,其自由端移位,从而弹性件的自由端与排水通孔的孔壁之间产生间隙,使得排水通孔流通。In other embodiments, the elastic structure may include an elastic member. When the elastic member is in the closed state, the free end of the elastic member is in sealing fit with the hole wall of the drainage through hole, so that the drainage through hole can be blocked. When the elastic member is switched from the closed state to the open state, its free end is displaced, so that a gap is created between the free end of the elastic member and the wall of the drainage through hole, allowing the drainage through hole to circulate.
请参考图2至图3,在一些实施例中,弹性件121在闭合状态时,沿排水通孔111的出水方向,弹性件121的自由端1212相比固定端1211更靠下游,即沿轮毂圈110的径向来看,弹性件121的自由端1212相对固定端1211向轮毂圈110的外侧倾斜。如此,外转子轮毂电机10在运行时,水在离心力作用下撞击弹性件121,同时在弹性件121自身的离心力作用下,弹性件121更加容易从闭合状态切换至打开状态,从而水更容易从排水通孔111排出。而且,若外界环境中的水进入排水通孔111内并处于弹性件121的外侧时,外界环境中的水对弹性件121的作用力较小时,会使得所述至少两个弹性件121的自由端1212之间更为聚集(或者使得一个弹性件121与排水通孔111的孔壁之间挤压的更紧),从而使得弹性结构120闭合的更紧,防水效果更好。Please refer to FIG. 2 to FIG. 3 , in some embodiments, when the
在其他实施例中,弹性件在闭合状态时,弹性件整体也可以是垂直于排水通孔的孔壁的,同时是垂直于轮毂圈的径向的。如此,外转子轮毂电机在运行时,轮毂外壳内部的水在离心力作用下撞击弹性件,也能使得弹性件从闭合状态切换至打开状态,从而将水排出。In other embodiments, when the elastic member is in the closed state, the entire elastic member may also be perpendicular to the hole wall of the drainage through hole, and at the same time be perpendicular to the radial direction of the hub ring. In this way, when the outer rotor hub motor is running, the water inside the hub shell hits the elastic member under the action of centrifugal force, which can also switch the elastic member from the closed state to the open state, thereby discharging the water.
请参考图1,在一实施例中,轮毂圈110上设有沿其周向间隔排列的多个排水通孔111,每个排水通孔111内设置有对应的弹性结构120。排水通孔111的数量例如是两个、三个等。Please refer to FIG. 1 , in one embodiment, a plurality of drain through
在其他实施例中,排水通孔的数量也可以是一个。In other embodiments, the number of drainage through holes may also be one.
请参考图2和图3,在一实施例中,轮毂外壳100还包括排水管130。排水管130设置在对应的排水通孔111内,排水管130的外壁与排水通孔111的孔壁密封配合。弹性结构120设置在对应的排水管130内,弹性件121的固定端1211与排水管130的内壁连接,从而弹性件121的固定端1211间接地与排水通孔111的孔壁连接。通过先将弹性结构120设置在对应的排水管130内,再将排水管130设置在对应的排水通孔111内,从而使得弹性结构120间接地设置在对应的排水通孔111,如此可方便弹性结构120的装配。Please refer to FIG. 2 and FIG. 3 , in an embodiment, the
在一实施例中,弹性结构120与排水管130的材质相同且一体成型,例如是硅胶材质等。通过先将弹性结构120与排水管130采用相同的材质一体成型,再将排水管130置入排水通孔111内,方便弹性结构120的装配。In one embodiment, the material of the
在一实施例中,排水通孔111可以是圆孔,也可以是方孔等形状。In an embodiment, the drainage through
请参考图4和图5,在一些实施例中,排水管130的形状与排水通孔111对应,可以是圆管,也可以是方管。Please refer to FIG. 4 and FIG. 5 , in some embodiments, the shape of the
请参考图6,在一些实施例中,排水通孔111为阶梯孔,包括相连通的第一孔1111和第二孔1112。第一孔1111的内径大于第二孔1112的内径,以使第一孔1111的孔壁与第二孔1112的孔壁的连接处形成台阶面1113。排水管130设置在第一孔1111内。如此设计,在安装排水管130时,只需将排水管130从第一孔1111背离第二孔1112的一侧塞入第一孔1111内,台阶面1113即可对排水管130进行限位,防止排水管130从第二孔1112移出,此时,只需要再通胶接等方式对排水管130背离台阶面1113的一侧进行限位即可,方便排水管130的装配,即方便弹性结构120的装配。沿轮毂圈110的径向,第一孔1111可以位于第二孔1112的外侧,也可以位于第二孔1112的内侧。Please refer to FIG. 6 , in some embodiments, the drainage through
请参考图2和图3,在一些实施例中,每个排水通孔111内设置有沿排水通孔111的轴向依次排列的多个弹性结构120,例如两个、三个、四个等。如此,可以通过多个弹性结构120进行层层防水,防水效果更好。Please refer to FIG. 2 and FIG. 3 , in some embodiments, each drainage through
在一实施例中,外转子轮毂电机10内部的易锈蚀器件(例如,定子、铁圈、磁钢等)的表面设置有防水胶,使得这些器件具备防水能力。In one embodiment, waterproof glue is provided on the surface of the rust-prone components (eg, stator, iron ring, magnet, etc.) inside the outer
