本实施例采用递进的方式撰写。
请如图1至图11所示，本发明实施例提供一种轮毂组件，包括：轮毂轴100；可旋转地套设于轮毂轴100上的轮毂200；设于轮毂轴100上，且置于轮毂200内，用于向轮毂200传递驱动力的行星齿轮组件300；可旋转地套设于轮毂轴100上，用于向行星齿轮组件300提供驱动力的动力输入件400；作用于行星齿轮组件300，用于切换驱动力的传递路径的控制组件500；作用于控制组件500以切换驱动力的传递路径的电动变速组件600；设置在轮毂200内的用于向轮毂200提供驱动力的驱动电机10。
本发明提供的轮毂组件，与现有技术相比较，由于设置有电动变速组件600与驱动电机10，其中，电动变速组件600能够及时作用于控制组件600切换驱动力的传递路径，简单操作即可实现档位的切换，而驱动电机10能够向轮毂200提供驱动力，助力于轮毂200转动，因此，不仅能够实现自行车的准确、简单变速，且使骑行者在骑行的过程中更加省力，提高了使用者的骑行体验。
作为一种优选的实施方式，可以设置力矩传感器和/或速度传感器和/或陀螺仪，电动变速组件600或驱动电机10可以根据力矩传感器和/或速度传感器和/或陀螺仪所监测的信号实现变速器的自动变速，或者驱动电机10的自动助力。采用该结构，可以使骑行者无需进行变速操件，进一步提高了骑行者的骑行体验。
本发明实施例中的轮毂轴100固定安装于自行车的车架上。
本发明实施例中的轮毂200能够相对于轮毂轴100转动，其可以安装辐条，轮毂200转动，自行车轮转动，且轮毂200的转速与自行车轮的转速一致。
本实施例中的行星齿轮组件300，包括，能够绕轮毂轴100转动的中心轮310，与中心轮310啮合的行星轮320，与行星轮320啮合的内齿圈330，用于保持行星轮320的行星架340。其中，内齿圈330与轮毂200固定。行星齿轮组件300设置有两组及以上，以实现驱动力通过不同的路径 传递。
本实施例中的动力输入件400，包括，飞轮座410与飞轮420。其中，飞轮420固定安装于飞轮座410上，飞轮座410通过第一轴承411安装于轮毂轴100上。飞轮420受力转动带动飞轮座410转动。飞轮座410与内齿圈330之间设置单向离合器或者棘爪机构430，以使得当飞轮座410的转速大于内齿圈330的转速时，驱动力通过飞轮座410经单向离合器或者棘爪机构430传递给内齿圈330，当飞轮座410的转速小于内齿圈330的转速时，驱动力不再通过飞轮座410直接传递给内齿圈330，而经由行星齿轮组件300变速后传递给内齿圈330。其中，飞轮座410与行星架340固定连接，当飞轮座410转动的同时，带动行星架340转动。
本发明实施例中，飞轮座410上设置有安装腔412，轮毂200靠飞轮420的一端置于安装腔412内，并通过第二轴承413安装于安装腔412内。如此设置，能够使得内齿圈330、单向离合器或者棘爪机构430、飞轮座410、第二轴承413配合部基本处于一纵切面上，极大减小了内变速器的宽度，使其结构更加紧凑，减小自行车架的开档。
本发明实施例中的控制组件500，包括：安装在轮毂轴100上的座体510；设置在座体510上的切换件520；作用于切换件520，以切换切换件520与行星齿轮组件300的中心轮310的卡合或分离状态的控制套530。
其中，座体510上设置有第一槽与第二槽，切换件520放置于一端放置于第一槽内，在扭簧的作用下切换件520另一端与中心轮310的内周面卡合，将中心轮310锁定，使得中心轮310不转动；当控制套530转动时，控制套530作用于切换件520，将切换件520的另一端压在第二槽内，此时切换件520与中心轮310处于分离状态，中心轮310能够转动。切换件520有多个，其数量与中心轮匹配，控制套530的转动，使得多个切换件520在卡合与分离状态切换。
其中，座体510可以通过键或者扁位的方式与轮毂轴100固定，使得座体510不会相对于轮毂轴100转动。
本发明实施例中的电动变速组件600，包括：安装在控制电机610；带有推动部621且与控制套530连接的控制环620；受控制电机610带动， 作用于推动部621使控制环620绕轮毂轴100转动的传动件630。
当力矩传感器和/或速度传感器和/或陀螺仪监测到的信号传递给控制电机610，控制电机610运行，作用于传动件630，通过传动件630作用于推动部621，使得控制环620转动，由于控制环620与控制套530连接，因此，控制套530转动，切换切换件520的状态，以改变驱动力的传递路径。
优选的，传动件630，包括：传动环631；设置在传动环631外周面上的齿部632；受控制电机610驱动，且与齿部632啮合的蜗轮蜗杆结构633；设置在传动环631上，作用于推动部621的推动件634。
控制电机610带动蜗轮蜗杆结构633从而作用于齿部632，由于齿部632与蜗轮蜗杆结构633啮合，因此，传动环631转动，使得推动件634推动推动部621，从而带动控制环620转动，实现控制套530转动。
优选的，在传动环631上设置有安装孔635，在安装孔635内设置有弹簧636，推动件634与弹簧636连接。推动634一端与弹簧636接触，一端与推动部621接触，使得弹簧636处于压缩状态。弹簧636的设置，能够使得传动环631与推动部621之间具有缓冲，对电机起保护作用。
本发明实施例提供的轮毂组件，还包括有安装于轮毂轴100的安装座640，电动变速组件600安装于安装座640上。
具体的，在安装座640上设置在环形腔641，传动环632套设在环形腔641内，控制电机610与蜗轮蜗杆结构633均置于环形腔641内。采用该结构，能够节省轮毂组件的轴向的空间，使得轮毂组件的宽度更加合理，能够减小自行车架的开档。
本发明实施例提供的轮毂组件，还包括：安装于安装座640上的霍尔板642；设置于传动环631上的定位磁铁643。当进行换档时，传动环631转动，处于传动环631上的定位磁铁643随之转动，当转动到位后，霍尔板642与定位磁铁643对应，如此，能够保证换档更加准确。
本发明实施例还提供一种自行车，包括上述任意一项所述的轮毂组件。
对所公开的实施例的上述说明，使本领域专业技术人员能够实现或使 用本发明。对这些实施例的多种修改对本领域的专业技术人员来说将是显而易见的，本文中所定义的一般原理可以在不脱离本发明的精神或范围的情况下，在其它实施例中实现。因此，本发明将不会被限制于本文所示的这些实施例，而是要符合与本文所公开的原理和新颖特点相一致的最宽的范围。
