图1是本发明中所涉及的多电机驱动结构100的结构示意图；图2是本发明中所涉及的多电机驱动结构100的剖视图；图3是本发明中所涉及的第一驱动组件和第二驱动组件的结构示意图；图4是本发明中所涉及的第一蜗轮和第二蜗轮的结构示意图。
如图1至图4所示，本发明较佳实施例提供了一种多电机驱动结构100。多电机驱动结构100包括:壳体组件60、第一齿轮17、第二齿轮41、第一转轴18、第二转轴42、第一驱动组件、第二驱动组件、传动结构80和转盘70。
壳体组件60包括箱体61和盖体62，箱体61和盖体62围设形成容纳腔601。箱体61和盖体62可以通过螺丝固定。
第一转轴18可以相对固定地安装于壳体组件60，第二转轴42可转动地安装于壳体组件60，第一转轴18和第二转轴42的轴线相互平行，第二转轴42的两端分别可转动地承接于箱体61和盖体62。第一齿轮17与第一传动轮15固定连接且可转动地安装于第一转轴18，第二齿轮41固定地安装于第二转轴42，第一齿轮17和第二齿轮41相互 啮合。第一转轴18上的第一传动轮15通过齿轮传动机构将动力传递给第二转轴42。第一齿轮17的齿数可以少于第二齿轮41的齿数，从而能够加大第二转轴42的输出力矩。
第一驱动组件包括依次传动连接的第一电机11、第一传动机构13和第一传动轮15，第一传动轮15可转动地安装于第一转轴18，第一电机11安装于壳体组件60并用于通过第一传动机构13驱动第一传动轮15转动。
第二驱动组件包括依次传动连接的第二电机12、第二传动机构14和第二传动轮16，第二传动轮16可转动地安装于第一转轴18，第二电机12安装于壳体组件60并用于通过第二传动机构14驱动第二传动轮16转动。
第一传动轮15和第二传动轮16可以选自蜗轮、齿轮和带轮中的任一种，第一传动机构13、第二传动机构14分别为与第一传动轮15、第二传动轮16适配的蜗杆、齿轮或带轮与皮带。即第一电机11和第二电机12可以通过蜗轮蜗杆传动机构、齿轮传动机构或带传动机构分别驱动第一传动轮15和第二传动轮16旋转。优选地，第一传动轮15和第二传动轮16分别是第一蜗轮15A和第二蜗轮16A，第一传动机构13和第二传动机构14分别为第一蜗杆13A和第二蜗杆14A，第一电机11和第二电机12的转轴分别与第一蜗杆13A和第二蜗杆14A连接。第一蜗杆13A和第二蜗杆14A分别与第一蜗轮15A和第二蜗轮16A啮合。第一电机11通过第一蜗杆13A驱动第一蜗轮15A转动，第二电机12通过第二蜗杆14A驱动第二蜗轮16A转动。
第一传动轮15、第二传动轮16、第一齿轮17和第二齿轮41均位于容纳腔601内，第一电机11和第二电机12均安装于箱体61的外侧。由此，能够保护上述传动部件。
传动结构80用于连接第一传动轮15和第二传动轮16以传递动力。传动结构80包括分别设于第一传动轮15和第二传动轮16上的第一卡接部81和第二卡接部82，第一卡接部81和第二卡接部82相互卡接，沿着第一传动轮15或第二传动轮16的旋转方向，第一卡接部81和第二卡接部82之间存在间隙。
如图4所示，在一示例中，第一卡接部81和第二卡接部82中的一个为卡块162，另一个为卡槽152，卡槽152包括相对设置的第一侧壁1521和第二侧壁1522，卡块162位于第一侧壁1521和第二侧壁1522之间，卡块162与第一侧壁1521抵接并与第二侧壁1522存在间隙。
图5是本发明中所涉及的另一种卡接方式的结构示意图；图6是本发明中所涉及的另一种卡接方式的另一视角的结构示意图。
如图5和图6所示，在另一示例中，第一卡接部81为卡柱153，第二卡接部82为卡孔163，卡柱153插入卡孔163内，卡柱153与卡孔163的侧壁之间存在间隙。
可见，第一卡接部81与第二卡接部82的卡接，可以是卡块162与卡槽152的卡接，也可以是卡柱153与卡孔163的卡接。无论是卡块162与卡槽152的卡接，还是卡柱153与卡孔163的卡接，第一卡接部81与第二卡接部82均在第一传动轮15或第二传动轮16的旋转方向存在间隙，以在第一传动轮15和第二传动轮16之间形成缓冲，避免第一卡接部81与第二卡接部82的侧壁过渡挤压造成第一电机11和第二电机12的电流增大而损坏，提高了第一电机11和第二电机12的寿命。第一卡接部81与第二卡接部82的形状不定，第一卡接部81可以是块状或柱状，第二卡接部82可以是与之对应的方槽或长槽或者孔。第一卡接部81与第二卡接部82的数量可以是多个。
第一传动轮15设有转动部151，第二传动轮16设有用于容纳转动部151的凹槽161，第一卡接部81和第二卡接部82中的一个设置于转动部151，另一个设置于凹槽161。
具体地，如图3和图4所示，第一传动轮15为第一蜗轮15A，第一卡接部81设于转动部151，第一卡接部81为卡槽152；第二传动轮16为第二蜗轮16A，第二卡接部82设于凹槽161，第二卡接部82为自凹槽161的内底壁和内侧壁上凸起的卡块162，转动部151安装于凹槽161内，卡块162卡入卡槽152，使得第一蜗轮15A和第二蜗轮16A通过块162和卡槽152的相互作用传递力矩。当第一电机11、第二电机12转动时，第一蜗杆13A带动第一蜗轮15A转动，第二蜗杆14A带动第二蜗轮16A转动，同时第二蜗轮16A通过卡块162作用于卡槽152的侧壁，施加推力于第一蜗轮15A，以增加第一蜗轮15A的输出力矩。其中，卡块162与卡槽152存在间隙，以在第一蜗轮15A和第二蜗轮16A之间形成缓冲，避免第一电机11、第二电机12由于转速误差过大而造成电流过大，使得第一电机11、第二电机12可以自动调整转速，从而达到第一电机11、第二电机12转速的同步而平稳转动，进而使其电流稳定。卡块162与卡槽152的数量可以是两个或者多个，且在圆周上均匀分布。
如图5和图6所示，第一卡接部81为圆柱形的卡柱153，卡柱153设于第一蜗轮15A；第二卡接部82为卡孔163，卡孔163设于第二蜗轮16A，在第二蜗轮16A的旋转方向上，卡孔163的长度大于卡柱153的直径。卡柱153和卡孔163的数量均是两个，且在圆周上均匀分布。
第二转轴42和转盘70可以组成用于输出动力的输出组件。转盘70位于壳体组件60的外侧且与第二转轴42固定连接，转盘70设有柱状凸起71，柱状凸起71偏离第二转轴42的旋转轴线。转盘70可以是曲柄结构，柱状凸起71用于与其他的连杆铰接，从而将旋转运动转换为线性 运动。具体地，输出组件包括第二齿轮41、设于第二齿轮41一端上的套接部43、设于第二齿轮41另一端上的第二转轴42、套在套接部43上的轴套50以及与套接部43固定连接的转盘70，套接部43通过轴套50转动地安装在盖体62上，第一齿轮17与第二齿轮41啮合，以带动第二齿轮41转动，第二齿轮41带动转盘70转动。
优选地，多电机驱动结构100还包括转动地安装于第一转轴18上的至少一个连接件20，连接件20为单个时，连接件20通过传动结构80连接第一传动轮15和第二传动轮16；当连接件20为多个时，多个连接件20设于第一传动轮15和第二传动轮16之间，相邻连接件20之间通过传动结构80连接，相邻的连接件20与第一传动轮15之间、相邻的连接件20与第二传动轮16之间均通过传动结构80连接。
图7是本发明中所涉及的连接件20的装配结构示意图。
如图7所示，第一蜗轮15A和第二蜗轮16A之间设有连接件20，以增加缓冲效果，连接件20的两端分别设有第一卡接部81和第二卡接部82，第一卡接部81和第二卡接部82可以分别是卡孔21和卡柱22，连接件20分别通过卡孔21和卡柱22与第一蜗轮15A上的卡柱和第二蜗轮16A上的卡孔传动连接。连接件20可以起到缓冲的作用。在传动过程中，卡接零件容易损坏，而蜗轮的制造成本通常比较贵，连接件20的设置还可以起到便于更换，降低维护成本的作用。
图8是本发明中所涉及的连接件20的另一种卡接方式的装配结构示意图。
如图8所示，连接件20的两端分别设有第一卡接部81和第二卡接部82，第一卡接部81和第二卡接部82可以分别是卡槽23和卡柱22，连接件20分别通过卡槽23和卡柱22与第一蜗轮15A上的卡块和第二蜗轮16A上的卡孔传动连接。
优选地，多电机驱动结构还包括至少一个第三驱动组件，第三驱动组件包括依次传动连接的第三电机、第三传动机构和第三传动轮30，第三传动轮30可转动地安装于第一转轴18，第三电机安装于壳体组件60，当第三驱动组件为单个时，第三传动轮30通过传动结构80与第一传动轮15和第二传动轮16。当第三驱动组件为多个时，多个第三传动轮30设于第一传动轮15和第二传动轮16之间，相邻第三传动轮30之间通过传动结构80连接，相邻第三传动轮30与第一传动轮15之间、相邻第三传动轮30与第二传动轮16之间均通过传动结构80连接。
图9是本发明中所涉及的第三传动轮30的装配结构示意图；图10是本发明中所涉及的第三传动轮30的另一视角的装配结构示意图。
如图9和图10所示，第一蜗轮15A和第二蜗轮16A之间设有第三蜗轮30A，第三蜗轮30A的两端分别设有第一卡接部81和第二卡接部82，第一卡接部81和第二卡接部82可以分别是卡孔31和卡柱32，第三蜗轮30A分别通过卡孔31和卡柱32与第二蜗轮16A和第一蜗轮15A传动连接。第三蜗轮30A由第三电机通过第三蜗杆驱动，从而进一步增加驱动力。
多电机驱动结构100还可以包括更多的驱动组件，例如更多的第三驱动组件，共同驱动第一转轴18转动，以提高多电机驱动结构100的输出动力。
在本实施例中，第一电机11通过第一传动机构13驱动第一传动轮15转动，第二电机12通过第二传动机构14驱动第二传动轮16转动，第二传动轮16通过传动结构80将动力施加于第一传动轮15，由此，能够增加第一传动轮15的输出动力。第一传动轮15通过第一齿轮17与第二齿轮41啮合驱动第二转轴42转动。由此，能够增加第二转轴42的输出动力。第二转轴42可以通过转盘70输出用于按摩的运动驱动力。第一 卡接部81与第二卡接部82之间存在间隙，以在第一传动轮15和第二传动轮16之间形成缓冲，避免第一卡接部81与第二卡接部82的过渡挤压造成第一电机11和第二电机12的电流增大而损坏，提高了第一电机11和第二电机12的寿命。
本申请还提供了一种按摩器，其包括驱动结构和动作组件，驱动结构与动作组件连接并用于向动作组件提供旋转驱动力，动作组件用于输出用于按摩的震动运动或伸缩运动。动作组件可以为偏心组件或伸缩活动组件，通过多电机驱动结构100带动偏心组件转动而使按摩器产生震动，或多电机驱动结构100带动伸缩活动组件往复运动而使按摩器产生伸缩冲击按摩。在一些示例中，多电机驱动结构100可以去掉转盘70，在第二转轴42上设置偏心块，第二转轴42驱动偏心块旋转从而产生震动。在另一些示例中，动作组件可以包括连杆、壳体和滑块，壳体设有供滑块线性移动的导向槽，连杆的一端与转盘70上的柱状凸起71铰接，另一端与滑块铰接，转盘70和连杆组成曲柄连杆传动机构，能够驱动滑块做往复直线运动，实现伸缩运动的功能，可以用于按摩。
显然，以上所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例，附图中给出了本申请的较佳实施例，但并不限制本申请的专利范围。本申请可以以许多不同的形式来实现，相反地，提供这些实施例的目的是使对本申请的公开内容的理解更加透彻全面。尽管参照前述实施例对本申请进行了详细的说明，对于本领域的技术人员来而言，其依然可以对前述各具体实施方式所记载的技术方案进行修改，或者对其中部分技术特征进行等效替换。凡是利用本申请说明书及附图内容所做的等效结构，直接或间接运用在其他相关的技术领域，均同理在本申请专利保护范围之内。
