如图1至图6所示，本实施例提供一种用于按摩器具的按摩机芯，包括机架86、安装在机架86上的驱动轴58、安装在驱动轴58上的第一偏心轮27、安装在驱动轴58上的第二偏心轮28、套设有第一偏心轮27上的前按摩臂26、套设在第二偏心轮28上的后按摩臂30、与前按摩臂26活动连接的第一连杆50、及与后按摩臂30活动连接的第二连杆39，驱动轴58能带动第一偏心轮27和第二偏心轮28转动，前按摩臂26的一端设有第一传动孔，第一偏心轮27嵌在第一传动孔中，前按摩臂26的另一端设有前按摩头23，后按摩臂30的一端设有第二传动孔，第二偏心轮28嵌在第二传动孔中，后按摩臂30的另一端设有后按摩头45，前按摩头23和后按摩头45沿前后方向间隔分布，且第一连杆50的另一端与机架86活动连接，第二连杆39的另一端与机架86活动连接；当驱动轴58带动第一偏心轮27和第二偏心轮28一起转动时，第一偏心轮27将通过前按摩臂26带动前按摩头23沿前后方向移动，第二偏心轮28将通过后按摩臂30带动后按摩头45沿前后方向移动，且当前按摩头23向后移动时，后按摩头45将向前移动；当前按摩头23向前移动时，后按摩头45将向后移动。在使用时，前按摩头23和后按摩头45将与人体接触；本用于按摩器具的按摩机芯，利用第一偏心轮27与前按摩臂26的配合关系，第二偏心轮28与后按摩臂30的配合关系，并利用第一连杆50与前按摩臂26的活动连接作用，及第二连杆39与后按摩臂30的活动连接作用，在驱动轴58转动时，将通过第一偏心轮27及前按摩臂26带动前按摩头23沿前后方向移动，并通过第二偏心轮28及后按摩臂30带动后按摩头45沿前后方向移动，且当前按摩头23向后移动时，后按摩头45将向前移动；当前按摩头23向前移动时，后按摩头45将向后移动，从而实现了抓的动作、即拿捏按摩，且此种按摩方式的按摩效果更好。同时，本用于按摩器具的按摩机芯的结构简单，体积较小，制造成本较低。
如图4所示，本实施例中驱动轴58包括驱动主轴段581和驱动倾斜轴段582，驱动倾斜轴段582的中心轴线和驱动主轴段581的中心轴线之间具有夹角α，且α为锐角，即驱动倾斜轴段582相对于驱动主轴段581产生一定的倾斜，驱动主轴段581和驱动倾斜轴段582均 能绕驱动主轴段581的中心轴线旋转，第一偏心轮27和第二偏心轮28均安装在驱动倾斜轴段582上。这样，驱动轴58转动时，其驱动倾斜轴段582绕驱动主轴段581的中心轴线旋转，驱动倾斜轴段582在带动第一偏心轮27和第二偏心轮28自转的同时，还带动第一偏心轮27和第二偏心轮28绕驱动主轴段581的中心轴线并沿环形轨迹转动，从而会通过前按摩臂26带动前按摩头23沿环形轨迹移动，并通过后按摩臂30带动后按摩头45沿环形轨迹移动，进而利用前按摩头23和后按摩头45实现揉的动作；结合前按摩头23和后按摩头45能进行抓的动作，就实现了抓揉按摩。
如图1和图4所示，本实施例中机架86上安装有敲击轴52，敲击轴52包括敲击主轴段和敲击偏心轴段，敲击偏心轴段的中心轴线和敲击主轴段的中心轴线相平行，即敲击偏心轴段相对于敲击主轴段产生一定偏移，敲击偏心轴段和敲击主轴段均能绕敲击主轴段的中心轴线旋转，敲击偏心轴段上安装有第一轴承49和第二轴承38，第一轴承49上安装有第一轴承座47，第二轴承38上安装有第二轴承座41，第一连杆50的另一端与第一轴承座47活动连接，第二连杆39的另一端与第二轴承座41活动连接。这样，敲击轴52旋转时，敲击偏心轴段将绕敲击主轴段的中心轴线做偏心运动，从而带动第一轴承座47及第二轴承座41做偏心运动，第一轴承座47再通过第一连杆50给前按摩臂26及前按摩头23施加沿敲击主轴段径向的力，第二轴承座41再通过第二连杆39给后按摩臂30及后按摩头45施加沿敲击主轴段径向的力，进而使得前按摩头23和后按摩头45能对人体产生敲击的动作，达到敲击按摩效果。另外，如图1所示，本实施例中第一连杆50的一端设有第一球形部，前按摩臂26上设有第一球形槽，第一球形部嵌在第一球形槽中，实现第一连杆50的一端与前按摩臂26间的活动连接，第一连杆50的另一端通过第一铰接轴与第一轴承座47铰接，实现第一连杆50的另一端与第一轴承座47间的活动连接，第二连杆39的一端设有第二球形部，后按摩臂30上设有第二球形槽，第二球形部嵌在第二球形槽中，实现第二连杆39的一端与后按摩臂30间的活动连接，第二连杆39的另一端通过第二铰接轴与第二轴承座41铰接，实现第二连杆39的另一端与第二轴承座41间的活动连接。更具体地，如图1所示，本实施例中前按摩臂26包括前按摩臂主体和安装在前按摩臂主体上的第一压块56，前按摩臂主体和第一压块56之间形成所述第一球形槽，后按摩臂30包括后按摩臂主体和安装在后按摩臂主体上的第二压块34，后按摩臂主体和第二压块34之间形成所述第二球形槽。第一铰接轴由轴肩螺钉53构成；第二铰接轴由轴肩螺钉42构成。
如图1至图6所示，本实施例中第一偏心轮27、第二偏心轮28、前按摩臂26、后按摩臂30、第一连杆50、第二连杆39、第一轴承49、第二轴承38、第一轴承座47及第二轴承 座41构成揉敲组件65，揉敲组件65有两个，两个揉敲组件65分别为左揉敲组件和右揉敲组件，左揉敲组件安装在驱动轴58的左端和敲击轴52的左端上，右揉敲组件安装在驱动轴58的右端和敲击轴52的右端上。具体地，驱动主轴段581的左右两端分别与两个驱动倾斜轴段582固定连接，敲击主轴段的两端分别与两个敲击偏心轴段固定连接；左揉敲组件的第一偏心轮27和第二偏心轮28安装在位于驱动主轴段581左侧的驱动倾斜轴段582上，且左揉敲组件的第一轴承49和第二轴承38安装在位于敲击主轴段左侧的敲击偏心轴段上；右揉敲组件的第一偏心轮27和第二偏心轮28安装在位于驱动主轴段581右侧的驱动倾斜轴段582上，且右揉敲组件的第一轴承49和第二轴承38安装在位于敲击主轴段右侧的敲击偏心轴段上。本实施例利用两个揉敲组件65，增强对人体的按摩效果。
如图5和图6所示，本实施例中用于按摩器具的按摩机芯，还包括车架66，机架86的一端通过强弱旋转轴1与车架66铰接，驱动轴58安装在机架86的另一端上，且机架86的另一端上还安装有扇形齿条2，车架66上安装有强弱驱动组件72，强弱驱动组件72包括与扇形齿条2相啮合的强弱调节齿轮。在需要时，强弱调节齿轮转动，通过其与扇形齿条2的啮合作用，驱动扇形齿条2及机架86一起相对于车架66并绕强弱旋转轴1旋转，以带动前按摩头23和后按摩头45沿靠近和远离人体方向移动，实现对按摩力度的调整。同时，如图2和图4所示，本实施例中机架86的另一端上设有强弱限位件7，强弱限位件7的两端分别设有第一限位凸起和第二限位凸起，第一限位凸起和第二限位凸起均用于与车架66上的限位部相抵触，以限制机架86相对于车架66旋转的幅度，进而防止按摩力度过大或过小。
如图1所示，本实施例中前按摩臂26的另一端上安装有前滚轮，前滚轮构成所述前按摩头23，后按摩臂30的另一端上安装有后滚轮，后滚轮构成所述后按摩头45，以利用前滚轮和后滚轮能自由滚动的特性，避免前按摩头23和后按摩头45在对人体进行按摩时，与人体间产生较大摩擦力，影响按摩效果。前滚轮为双按摩轮，材质为硅胶；后滚轮为单按摩轮，材质为硅胶。
如图1至图3所示，本实施例中第一偏心轮27和第二偏心轮28沿驱动轴58的轴向依次分布，前按摩臂26的中部设有沿驱动轴58的轴向弯折的弯折部，前按摩臂26的另一端与后按摩臂30的另一端在驱动轴58的轴向上相对应，进而使得前按摩头23和后按摩头45沿驱动轴58的轴向上相对应，增强拿捏按摩效果。
如图3所示，本实施例中揉敲组件65还包括抓揉电机15，抓揉电机15通过皮带传动机构带动蜗轮蜗杆传动机构运行，并通过蜗轮蜗杆传动机构减速后将扭矩传导给驱动轴58。具体地，第一皮带轮11安装在抓揉电机15的输出轴上，第二皮带轮13安装在蜗杆10上，第 一皮带14套设在第一皮带轮11和第二皮带轮13上，蜗杆10与安装在驱动轴58上的蜗轮6相啮合，蜗轮6采用斜齿轮。
如图1和图3所示，本实施例中敲击轴52与减速箱体8相连接，敲击电机18通过减速箱体8带动敲击轴52转动。减速箱体8中设有第三皮带轮16、第二皮带17及第四皮带轮19。敲击电机18通过第三皮带轮16、第二皮带17及第四皮带轮19减速后传递扭矩给敲击轴52。
本实施例中前按摩臂26和后按摩臂30均为曲臂。第一连杆50和第二连杆39均为一种球头连杆。第一偏心轮27、前按摩臂26、第一连杆50、敲击轴52、减速箱体8共同构建了第一个五连杆机构；第二偏心轮28、后按摩臂30、第二连杆39、敲击轴52、减速箱体8共同构建了第二个五连杆机构。本实施例中前滚轮安装在前按摩臂26另一端的前按摩球轴上；后滚轮安装在后按摩臂30另一端的后按摩球轴上。
如图1所示，本实施例中驱动轴58通过两根圆柱销59传递扭矩给第一偏心轮27和第二偏心轮28。驱动轴58带动第一偏心轮27和第二偏心轮28一起转动时，第一偏心轮27带动前按摩臂26沿前后且沿径向摆动，第二偏心轮28带动后按摩臂30沿前后且沿径向摆动。且本实施例中第一偏心轮27距离驱动倾斜轴段582最远的侧边部和第二偏心轮28距离驱动倾斜轴段582最远的侧边部分别位于驱动倾斜轴段582的两侧，且呈对称分布。这样，第一偏心轮27带动前按摩臂26向前摆动时，第二偏心轮28带动后按摩臂30向后摆动；第一偏心轮27带动前按摩臂26向后摆动时，第二偏心轮28带动后按摩臂30向前摆动，这样就实现了抓的动作。同时，由于驱动轴58的倾斜结构设计，使得前按摩臂26和后按摩臂30实现了揉的动作，两者结合起来就实现了抓揉的动作。另外，敲击轴52基于其轴端的偏心结构设计，通过第一连杆50和第二连杆39分别带动前按摩臂26和后按摩臂30实现了敲击、抖动或叩击的动作。敲击和抓揉功能结合在一起，就可以实现边抓揉边抖动的效果。强弱驱动组件72的强弱调节齿轮驱动扇形齿条2，带动揉敲组件65绕强弱旋转轴1上下旋转，实现按摩力度的强弱变化。综上，抓揉、抖动和上下强弱三项功能一起综合运用实现了仿人手抓揉拿捏按摩的效果。
本实施例中后按摩臂30和前按摩臂26具体均为PA66+40％GF的金属嵌件。驱动轴58通过第三轴承5安装在机架86上。蜗杆10通过第四轴承9和第五轴承12安装在减速箱体8中。第一偏心轮27和第二偏心轮28的材质均为压铸铝合金。第一压块56和第二压块34的特性为PA66+40％GF。第一连杆50和第二连杆39的材质均为45#钢。第一轴承座47和第二轴承座41的特性为PA66+40％GF。敲击轴52的材质为40Cr调质。驱动轴58的材质为40Cr调质。车架66上安装有行走组件73，行走组件73包括行走驱动马达83和行走轮84。强弱 驱动组件72还包括强弱驱动马达85。位于敲击主轴段左侧的敲击偏心轴段为左偏心轴段81，位于敲击主轴段右侧的敲击偏心轴段为右偏心轴段82。另外，如图1至图6所示，本用于按摩器具的按摩机芯还包括如下部件：
