如图1和图2所示，本申请提供了一种车轮轮毂的实施例，其中，该车轮轮毂的轴线处具有与车体10固定连接的固定轴21a，固定轴21a为中空结构。该车轮轮毂还包括轮毂灯30，轮毂灯30的电源线从固定轴21a中穿过并与设置于车体10内的电源相连接，轮毂灯30固定在固定轴21a的靠近车轮轮毂外侧面的一端。其中，车轮轮毂及固定在车轮轮毂外围的轮胎组成车辆的车轮20。
这里的轮毂灯30是指现有技术或者未来发展技术中供电可以亮的光源。例如，轮毂灯30可以是常规的灯，也可以是发光二极管(Light Emitting Diode，LED)灯。
可以理解的是，这里的车轮轮毂还具有轮毂本体，车轮20在行驶时，固定轴21a不动，轮毂本体绕固定轴21a转动。其中，轮胎固定在轮毂本体上。
通过本实施例提供的车轮轮毂，将车轮轮毂的固定轴21a设置为中空结构并与车体10连接，轮毂灯30的电源线从固定轴21a中穿过并与车体 10的电源相连接，当车体的电源通电时，轮毂灯30亮；当车体的电源断电时，轮毂灯30灭，这样可以方便的起到指示车体工作状态的作用。通过车体10的电源直接对轮毂灯30进行供电，进而省去了轮毂灯电池对轮毂灯进行供电，以及在电池耗尽时更换电池的麻烦。并且，车体10的电源一般为充电电源，使得装置节能、环保；轮毂灯30的电源线通过固定轴21a内的中空结构与车体10的电源连接，能够避免车辆在行驶时电源线与其它结构发生干涉，很好地解决了电源线缠绕的问题，并且能够起到保护电源线的作用。
在本实施例中，为轮毂本体绕固定轴21a转动提供动力的动力源可以为马达，也可以为发动机。
在本实施例的一些可选的实现方式中，在车轮轮毂上可以设置有电机21，电机21包括转子，转子设置于固定轴21a上。这里的固定轴21a为电机21的定子；轮毂本体可以为这里的转子，也可以设置在这里的转子上。通过电机21的转子绕固定轴21a转动，使轮毂本体绕固定轴21a转动。可选的，电机21的电源线从固定轴21a中穿过并与车体10内的电源相连接。以使车体10的电源能够向电机21进行供电，并且，同样的，能够通过固定轴21a对电机21的电源线进行保护以及避免电机21的电源线在车轮20转动时发生缠绕。
具体地，电机21可以为轮毂电机，那么该电机21也充当了车轮轮毂的作用，该轮毂电机由定子(固定轴21a)和转子(轮毂本体)组成。电机在运行时，转子绕定子转动，从而带动转子上装配的轮胎转动，进而实现车辆行走功能。可以理解的是，电机21也可以为其他形式的电机，只要固定轴21a设置在电机21的定子上，轮毂本体设置在电机21的转子上即可。
如图1和图2所示，电机21上还可以设置有端盖21b，端盖21b位于车轮20的外侧并与电机21的转子固定连接，通过端盖21b从外侧保护电 机21。可选的，端盖21b在与轮毂灯30对应的位置上设有与轮毂灯30匹配的开口。这里的轮毂灯30可以位于端盖21b内侧，也可以位于端盖21b的开口中，还可以位于端盖21b外侧。图2示例性地示出了轮毂灯30位于端盖21b的开口中，这样既可以保证固定轴21a设置的短，也便于轮毂灯30后期的维修。当然，端盖21b也可以不设置开口，这里轮毂灯30位于端盖21b内侧，端盖21b为透明材料，以便轮毂灯30的光可以从透明材料的端盖21b射出。
这里的端盖21b与电机21的转子固定连接，车轮20在行驶时，这里的端盖21b会随着转子一起转动。
可以理解的是，端盖21b的开口与轮毂灯30匹配，轮毂灯30可以通过端盖21b的开口设置在固定轴21a上，以便后期维修轮毂灯30。
在本实施例中，当端盖21b上设置开口时，车轮轮毂还可以包括设置在端盖21b外侧的轮毂盖板，轮毂盖板覆盖轮毂灯30的开口，且轮毂灯30位于轮毂盖板内侧。这里的轮毂盖板可以与端盖21b的外表面固定连接，也可以与轮毂本体的其他结构固定连接。其中，将轮毂盖板设置在端盖21b的外侧，通过轮毂盖板进一步对装置进行保护。
具体地，轮毂盖板的面积可以大于端盖21b的面积，也可以小于端盖21b的面积。这里轮毂盖板的面积只需满足大于端盖21b的开口的面积即可，以通过轮毂盖板对端盖21b的开口处的轮毂灯30进行保护，避免外部物品触碰轮毂灯30。
轮毂灯30的光经端盖21b的开口以及轮毂盖板射出的实现方式有多种。以下示例性性地列出了几种具体地实现方式。
例如，在本实施例的一些可选的实现方式中，轮毂盖板的边缘与端盖21b之间形成透光部；并且，在端盖21b的外表面设置第一反光面，在轮毂盖板的内表面设置第二反光面，且第一反光面与第二反光面之间具有反射 空间。轮毂灯30从开口发出的光线经第一反光面和第二反光面反复折射后可从透光部射出。通过该方式可灵活设置轮毂灯30、开口以及透光部三者之间的位置，只要使光线满足反射要求即可。并且，通过设置第一反光面和第二反光面，能够使轮毂灯30发出的光更多地从透光部处射出。可以理解的是，在轮毂灯30的光线很强的情况下，在端盖21b与轮毂盖板的面上也可以不设置反光面。
又例如，再结合图3和图4所示，在本实施例的一些可选的实现方式中，该轮毂盖板包括第一盖板41和第二盖板42。其中，第一盖板41设置在端盖21b的外侧，且第一盖板41上设有通孔，第二盖板42覆盖在第一盖板41的通孔上。第二盖板42与第一盖板41之间形成透光部。如此可使轮毂灯30的灯光在通过第一盖板41上的通孔射出后，从第二盖板42与第一盖板41之间的透光部射出。可以理解的是，这里的第一盖板41可以与端盖21b固定连接，也可以与轮毂本体固定连接；这里的第二盖板42与第一盖板41可以为可拆卸连接，也可以为不可拆卸连接(例如，粘接)。第二盖板42的面积可以小于第一盖板41的面积，也可以大于第一盖板41的面积，还可以等于第一盖板41的面积。图1和图2示例性地示出了第二盖板42的面积小于第一盖板41的面积。
可以理解的是，在轮毂灯30的光线很强的情况下，在第一盖板41和第二盖板42的面上也可以不设置反光面。
这里的第一盖板41上设有通孔。可选的，通孔的位置与端盖21b的开口的位置相对应，以便轮毂灯30的灯光从通孔射出。可选的，通孔的位置与端盖21b的开口的位置相对应，且通孔的面积大于等于端盖21b的开口的面积，以便轮毂灯30后期的维修。
透光部的形状可以为多边形、圆形、间断的多边形或间断的圆形等中的一种或多种，如此使轮毂灯30发出的光线从透光部透出时形成不同的形 状。需要注意的是，当第二盖板42的面积小于第一盖板41的面积时，第二盖板42的边缘与第一盖板41之间形成透光部；当第二盖板42的面积大于第一盖板41的面积时，第一盖板41的边缘与第二盖板42之间形成透光部。当第二盖板42的面积等于第一盖板41的面积时，第一盖板41的边缘与第二盖板42的边缘之间形成透光部。
具体地，在本实施例中，在第一盖板41的外表面设置有第一反光面，在第二盖板42的内表面设置有第二反光面，第一反光面与第二反光面之间具有反射空间。通过第一反光面和第二反光面配合，以使轮毂灯30发出的光从第一盖板41和第二盖板42之间的透光部中透射出来。通过设置反光面，可以使光在第一盖板41和第二盖板42之间反复折射，并从第一盖板41和第二盖板42之间的透光部散射出来，增加了光的透射强度。
其中，第一盖板41和第二盖板42可通过紧固件进行连接，也可通过卡扣结构进行连接。图3至图6示例地示出了第一盖板41和第二盖板42通过卡扣结构连接。以方便拆装，并且该结构简单便于设计和制造。
具体地，再结合图5和图6所示，该卡扣结构包括卡槽51和卡钩52。其中，卡槽51设置在第一盖板41上，卡槽51上设置有避让部51a和限位部51b，避让部51a和限位部51b间隔设置，卡钩52设置在第二盖板42上，卡钩52从避让部51a进入卡槽51内，卡钩52与限位部51b配合限位，以使卡钩52固定在卡槽51内。
在本实施例中，在卡槽51的一端设置一缺口以形成避让部51a，在卡槽51的另一端设置限位槽以形成限位部51b，卡钩52具有弹性结构，卡钩52从缺口处进入卡槽51内并挤压变形，当卡钩52移动至限位槽处时，卡钩52翘起并卡入限位槽内以固定卡钩52，如此可将第二盖板42固定在第一盖板41上。
其中，为了将第二盖板42稳固在第一盖板41上，在第一盖板41和第 二盖板42上可以设置多组卡扣结构，多组卡扣结构沿第一盖板41和第二盖板42的中心环形间隔设置，卡槽51为弧形，在将第二盖板42安装在第一盖板41上时，只需将第二盖板42上的卡钩52位于避让部51a处时旋转第二盖板42，使卡钩52对应进入限位部51b处即可完成安装。
在本实施例中，车轮轮毂还可以包括设置在端盖21b的开口处的防水结构，通过该防水结构防止外部雨水或生活用水进入车轮20内，以对电机21和轮毂灯30造成短路和损坏。
防水结构的实现方式有多种。以下示例性性地列出了几种具体地实现方式。
例如，在本实施例的一些可选的实现方式中，该防水结构包括位于端盖21b上的凸起部，并在该凸起部上设有凹槽，凹槽内设有防水垫圈62。
为了进一步提高防水效果，该防水结构还包括防水盖61，防水盖61覆盖于透光孔上并与防水垫圈62配合，防水盖61与端盖21b固定连接，且防水盖61为透光材质。以在实现防水功能的同时不影响轮毂灯30的照射。
又例如，在本实施例的一些可选的实现方式中，该防水结构包括覆盖在端盖21b的开口上的防水盖，且防水盖61为透光材质。这里防水盖可以通过螺栓设置在端盖21b上，也可以通过粘接设置在端盖21b上。为了进一步提高防水效果，防水盖与端盖21b之间可以设置密封结构。具体地，防水盖与端盖21b之间可以涂密封胶，也可以设置密封弹垫，还可以设置防水垫圈62。
可选的，当防水盖与端盖21b之间设置防水垫圈62时，端盖21b的开口周围可以设置有环形的凹槽，凹槽与防水垫圈62相匹配，防水垫圈62的部分设置在凹槽内，防水垫圈62的剩余部分位于凹槽外，防水盖压在凹槽外的防水垫圈62的剩余部分上，并与端盖21b连接。这样，通过将防水盖与端盖21b之间的防水垫圈62挤压起到密封作用。
需要说明的是，车轮轮毂可以只设置有防水结构，也可以只设置有轮毂盖板，还可以同时设置有防水结构和轮毂盖板。图2示例性地示出了车轮轮毂既设置有轮毂盖板，也设置有防水结构。这里的防水结构在轮毂盖板的内侧。当轮毂灯30发生故障时，可以依次将轮毂盖板和防水结构取掉，方便轮毂灯30的维修。
通过本发明提供的车轮轮毂，将电机21的电源线以及轮毂灯30的电源线均通过固定轴21a的中空结构与车体10的电源相连接，使得电机21和轮毂灯30均通过电源进行供电，解决了现有技术中轮毂灯30需要频繁更换电池的问题。并且，通过该固定轴21a能够避免车轮20在转动过程中对电源线进行缠绕，解决了走线问题，对电源线进行保护。
本申请又一实施例提供了一种车辆，该车辆包括上述实施例提供的车轮轮毂。具体地，该车辆还包括电源、车体10和用于控制电机21和轮毂灯30的控制部。其中，车体10与车轮20相连接，电源位于车体10内，电源分别与电机21、轮毂灯30以及控制部电连接。控制部可根据电源和/或电机21的运行情况控制轮毂灯30。例如，可通过控制部控制轮毂灯30的颜色、发光模式等，使轮毂灯30常亮、闪烁或间隙性发亮等，通过上述发光模式结合车辆运行情况(电源电量低、行驶快或行驶慢等)，可以使使用者直观看到车辆运行情况，便于使用者使用。
应当理解的是，本领域技术人员可以根据实际需要通过控制部来控制轮毂灯30的发光模式。例如，通过控制部控制轮毂灯30的电压变大或变小，实现轮毂灯30变亮或变暗。又例如，通过控制部控制轮毂灯30间隔2秒或者3秒通电，实现轮毂灯30闪烁或间隙性发亮。再例如，通过控制部控制轮毂灯30中的部分颜色灯亮，剩余部分灯灭，实现轮毂灯30的颜色变化。再例如，通过控制轮毂灯30中部分灯亮，剩余部分灯灭，实现轮毂灯30的不同形状图案的变化。
具体地，在一些应用场景中，例如，当检测到电源的电量为60％～100％时，控制部可以控制轮毂灯30发出白光；当检测到电源的电量为30％～60％时，控制部可以控制轮毂灯30发出黄光；当检测到电源的电量为10％～30％时，控制部可以控制轮毂灯30发红光；当检测到电源的电量小于10％时，控制部可以控制轮毂灯发红光30，且一直闪烁。这样可以提醒用户及进存电。又例如，当检测到电机21出现故障时，控制部可以控制轮毂灯30发出橙光，且一直闪烁。
以上所述仅为本申请的可选实施例而已，并不用于限制本申请，对于本领域的技术人员来说，本申请可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本申请的保护范围之内。
