实施例1
参考图1-图8，本发明一种电子提拉美容仪，包括：本体1、按摩组件2和变速驱动装置3。变速驱动装置3用于输出不同的转速以 驱动按摩组件2的运动频率或运动速度。
本发明变速驱动装置3，包括：驱动件31、第一运动副32和第二运动副33；所述驱动件31正转时，驱动所述第一运动副32以第一速度运动；所述驱动件反转时，驱动所述第二运动副33以第二速度运动。所述第一速度和第二速度不同。在本实施例中，所述驱动件31分别与所述第一运动副32和第二运动副33单向传动连接，使得所述驱动件31正转或反转时，所述第一运动副32和第二运动副33中有且只有一个随着驱动件31转动。
为了实现单向传动连接，所述第一运动副32和第二运动副33分别设置有单向轴承。本实施例中，所述驱动件31包含电机310，第一齿轮311和轴杆312。所述第一运动副32为齿轮运动副、第二运动副33为皮带运动副。所述电极310的输出转轴与第一齿轮311啮合，第一齿轮311的轴心处设置有一轴杆312。
具体来说第一运动副32包括第二齿轮321和第三齿轮341，所述第二齿轮321的轴心处设置有第一单向轴承322，第一单向轴承322的内周通过轴杆312与第一齿轮311连接，第二齿轮321与第三齿轮341啮合。这样就可以通过电机310正转驱动第一齿轮311转动，第一齿轮311再通过轴杆312和第一单向轴承322带动第二齿轮321转动,从而带动第三齿轮341以第一速度转动。而驱动件31反转时，第一单向轴承322打滑，第二齿轮321也就停止转动。
另外第二运动副33包括第一皮带轮331和第二皮带轮342，皮带轮331的轴心处通过第二单向轴承332连接至所述轴杆312，所述 第一皮带轮331通过皮带与皮带轮342连接。所述电机310反转时，第二单向轴承332转动，从而驱动皮带轮331转动，带动皮带轮342以第二速度转动。而当所述电机310正转时，第二单向轴承332打滑，皮带轮331也就停止转动。
通过主动轴带动两组不同的运动副，而两组运动副有不同的传动比，从而使第三齿轮341第二皮带轮342的转动速度不同，也就实现了两组运动副输出的转速不同。
为了实现第一运动副32和第二运动副33带动按摩组件2运动，所述第一运动副32和第二运动副33与同一个转轴34连接，具体来说第一运动副32通过套设在转轴34上的第三齿轮341与转轴连接，第二运动副通过皮带与套色在转轴34上的皮带轮342连接；所述转轴34通过运动组件35与按摩组件2连动连接。这样无论两个运动副中的哪一个转动，转轴34和运动组件35都可以将转动传递至按摩组件2从而带动按摩组件2运动。
本实施例中按摩组件2的运动方式为沿着自身的轴向往复运动，从而对皮肤实现拍打按摩的效果，因此所述运动组件35为换向运动组件35，用于将转轴34的转动换向为按摩组件2沿着自身轴向上的往复运动。如果按摩组件2为转动按摩，那么运动组件35就只需要将转动传递给按摩组件2即可，无需进行换向。
具体来说：所述换向运动组件35包括与转轴34连动设置的凸轮351，以及活动连杆352；所述活动连杆352具有一空腔；凸轮351上的连动块置于所述空腔内；所述凸轮351转动时，连动块在所述空 腔内转动，带动活动连杆352沿着自身的轴向往复运动。活动连杆352的另一端与按摩组件2连接，因此活动连杆352往复运动时就可以带动按摩组件2往复运动，对皮肤进行拍打。
本实施例中为了让电子提拉美容仪具备微电流功能，所述按摩组件2为2组，每一组按摩组件2分别与不同的运动组件35连接。由于第一运动副32或者第二运动副33转动时，转轴34都会转动，因此两个运动组件35也都会驱动两组按摩组件2运动。
要实现微电流功能，两组所述按摩组件2分别通过导电件21与主控电路板4上的正极和负极连接；所述导电件21与按摩头导电连接。当按摩组件2与人体皮肤接触时，正极、导电件21、第一按摩组件、皮肤、第二按摩组件、导电件21、负极就形成闭合回路，从而对皮肤形成微电流刺激。
所述本体1上设置有模式按键11、开关按键12及霍尔电路板5；为了实现微电流强弱的调节，所述模式按键11用于切换微电流的强弱。为了实现按摩组件2拍打速度的调节，所述开关按键12用于开关机、以及切换第一运动副32或第二运动副33随着驱动件31转动。所述开关按键12具有自动复位功能，通过灌包在第二皮带轮342中的磁铁与霍尔电路板5配合实现。
本发明电子提拉美容仪使用时，长按开关按键2的开关健启动，进入模式一：微电流启动，短按模式按键11可切换微电流的强弱；
短按开关按键2可以切换进入模式二：电机310正转开启，驱动 第一齿轮311转动，第一齿轮311再通过轴杆312和第一单向轴承322带动第二齿轮321转动,从而带动第三齿轮341以第一速度转动；套设在转轴34上的第三齿轮341与转轴连接，通过换向运动组件35，将转轴34的转动换向为按摩组件2沿着自身轴向上的往复运动，按摩头做直线往复的拍打运动，此时为拍打速度为快档，微电流保留；快速拍打皮肤刺激皮肤细胞使皮肤更有弹性；
短按开关按键2切换进入模式三：电机310反转，驱动第一齿轮311转动，第一齿轮311再通过轴杆312和第二单向轴承332转动，从而驱动第一皮带轮331转动，带动第二皮带轮342以第二速度转动；套设在转轴34上的第二皮带轮342连接与转轴连接，通过换向运动组件35，将转轴34的转动换向为按摩组件2沿着自身轴向上的往复运动；按摩头做直线往复的拍打运动，此时为拍打速度为慢档，按摩头慢慢挤压皮肤，可以使皮肤血液循环更好，营养更容易吸收；
再次长按开关按键2关机，并自动复位。
上述的变速驱动装置3除了应用在电子提拉美容仪上，还可以应用在其它领域上，不应以本实施例限定变速驱动装置3的应用领域。
实施例2
参考图9，本实施例与实施例1的区别在于：本实施例中两个运动副都是齿轮运动副。
实施例3
参考图10，本实施例与实施例1的区别在于：本实施例中两个运动副都是皮带运动副。
以上所述，仅为本发明较佳的具体实施方式；但本发明的保护范围并不局限于此。任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，根据本发明的技术方案及其改进构思加以等同替换或改变，都应涵盖在本发明的保护范围内。
工业实用性
本发明变速驱动装置，通过电机正转和反转时带动不同的运动副转动，从而实现不改变电机运行功率的情况下改变输出转速。本发明应用范围广，可用于电子提拉美容仪，其快档快速拍打皮肤刺激皮肤细胞使皮肤更有弹性，慢档按摩头慢慢挤压皮肤，可以使皮肤血液循环更好，营养更容易吸收。
