具体实施方式
为了便于理解本发明，下面将对本发明进行更全面的描述。但是，本发明可以以许多不同的形式来实现，并不限于本文所描述的实施例。相反地，提供这些实施例的目的是使对本发明的公开内容的理解更加透彻全面。
除非另有定义，本文所使用的所有的技术和科学术语与属于本发明的技术领域的技术人员通常理解的含义相同。本文中在本发明的说明书中所使用的术语只是为了描述具体的实施例的目的，不是旨在于限制本发明。
请参阅图1至图9，为本发明一实施方式的活塞驱动机构20，用于用于带动筋膜枪100的按摩头50运动。该活塞驱动机构20包括驱动支架21、连接驱动支架21的驱动电机22、安装在驱动支架21上的齿轮组件23、活动设置在驱动支架21附近的传动活塞24、连接传动活塞24的第一连杆25、及连接传动活塞24的第二连杆26；齿轮组件23包括转动设置在驱动支架21上的第一齿轮片231、转动设置在驱动支架21上的第二齿轮片232、及安装在驱动电机22转轴上的驱动齿轮片233；驱动齿轮片233直接或间接驱动第一齿轮片231及第二齿轮片232同时转动；在平行第一连杆25或第二连杆26的活动范围的平面上，第一连杆25与第二连杆26从相反的方向同时靠近或同时远离传动活塞24的轴线摆动。
通过第一连杆25的两端分别与第一齿轮片231的侧面及传动活塞24枢接，第二连杆26的两端分别与第二齿轮片232的侧面及传动活塞24枢接，驱动齿轮片233驱动第一齿轮片231及第二齿轮片232转动时，传动活塞24在直线运 动的垂直方向上分别受到了第一连杆25与第二连杆26的限制作用，从而有效抵消了侧向力，避免传动活塞24在直线运动的垂直方向上产生了晃动，提高筋膜枪100的使用体验。
具体地，第一连杆25的两端分别与第一齿轮片231的侧面及传动活塞24枢接；第二连杆26的两端分别与第二齿轮片232的侧面及传动活塞24枢接。
请参阅图4及图5，在其中一个实施方式中，驱动支架21包括第一底板部211、相对设置在第一底板部211一侧的侧板部212、及连接在侧板部212之间的电机安装部213；第一齿轮片231与第二齿轮片232平行且相对设置；驱动齿轮片233与第一齿轮片231的边缘或内侧啮合；驱动齿轮片233还与第二齿轮片232的边缘或内侧啮合；第一连杆25靠近第一齿轮片231的一端与第一齿轮片231的内侧枢接；第二连杆26靠近第二齿轮片232的一端与第二齿轮片232的内侧枢接。具体地，第一齿轮片231的内侧为背向侧板部212的一侧，第二齿轮片232的内侧为背向侧板部212的一侧。
由于驱动齿轮片233处于第一齿轮片231与第二齿轮片232之间，使第一齿轮片231与第二齿轮片232沿同一轴线按相反的方向转动，且第一连杆25与第二连杆26同时推动传动活塞24远离驱动电机22或同时带动传动活塞24靠近驱动电机22，令传动活塞24在直线运动的垂直方向上的外力获得平衡，消除侧向力；优选地，为避免轮齿与连杆之间发生抵触，第一齿轮片231或第二齿轮片232的轮齿设置在边缘位置，且相对齿轮主体轴心倾斜设置。
请参阅图4，在其中一个实施方式中，第一齿轮片231或第二齿轮片232的中心容置有第一轴承件234；齿轮组件23还包括穿设在第一轴承件234中的第一销轴件235；第一销轴件235的端部与侧板部212固定连接；从而减少第一齿轮片231或第二齿轮片232与侧板部212之间的摩擦作用，提高活塞驱动机构 20的使用寿命。
在其中一个实施方式中，齿轮组件23还包括连接第一齿轮片231侧面或第二齿轮片232侧面的第二销轴件237；第二销轴件237偏离第一齿轮片231的中心或第二齿轮片232的中心设置；连接第一齿轮片231的第二销轴件237穿设在第一连杆25中；连接第二齿轮片232的第二销轴件237穿设在第二连杆26中。具体地，第二销轴件237连接第一齿轮片231的内侧或第二齿轮片232的内侧，在其他实施方式中，第二销轴件237还可以是连接第一齿轮片231或第二齿轮片232朝向相同的一侧。
在其中一个实施方式中，第一齿轮片231的内侧或第二齿轮片232的内侧设有偏离齿轮片中心的偏心孔236；第一连杆25的两端或第二连杆26的两端分别容置有第二轴承件261；第二销轴件237的主体穿设在第二轴承件261中；第二销轴件237的端部固定穿设在偏心孔236中；从而通过第二轴承件261减少第一连杆25与第一齿轮片231之间的摩擦作用或第二连杆26与第二齿轮片232之间的摩擦作用，提高活塞驱动机构20的使用寿命，同时方便连杆与齿轮片之间的装配；在其他实施方式中，第一齿轮片231或第二齿轮片232与第二销轴件237还采用一体化成型或焊接连接；进一步地，为调节第一连杆25与第一齿轮片231之间的间隙或调节第二连杆26与第二齿轮片232之间的间隙，齿轮组件23还包括套设在第二销轴件237上的轴套238，轴套238设置在第一连杆25与第一齿轮片231之间的或第二连杆26与第二齿轮片232之间。

在本实施方式中，由于驱动齿轮片233与第一齿轮片231啮合；第一齿轮片231的一侧或第二齿轮片232的一侧设有偏离齿轮片中心的偏心凸销239；第一连杆25的一端套设在第一齿轮片231的偏心凸销239上；第二连杆26的一端套设在第二齿轮片232的偏心凸销上；第一连杆25的另一端及第二连杆26的另一端通过限位销262与传动活塞24枢接；可选地，可通过令第一齿轮片231及第二齿轮片232的直径及齿数一致，使第一连杆25及第二连杆26同时靠近传动活塞24的轴线摆动或同时远离传动活塞24的轴线摆动。
请参阅图1至图3，本发明还提供一种筋膜枪100，包括活塞驱动机构20、容纳活塞驱动机构20的主壳组件30、用于对传动活塞24导向的导向组件40、连接传动活塞24的按摩头50、连接驱动电机22的控制电路60、及连接驱动电机22的储能件70。
具体地，控制电路60用于向活塞驱动机构20提供控制信号；储能件70用于向活塞驱动机构20或控制电路60提供电源；在驱动电机22的运作下，传动活塞24带动按摩头50产生冲击运动，对人体产生按摩效果。
请参阅图3，在其中一个实施方式中，导向组件40包括套设在传动活塞24上的缸体套41、套设在缸体套41外侧的第一缓冲软套42、及用于将缸体套41或第一缓冲软套42限定在主壳组件30一侧的定位环43；按摩头50靠近传动活塞24的一端套设有第二缓冲套51；在按摩头50沿轴向的振动过程中，通过第一缓冲软套42与第二缓冲软套51的接触，对按摩头50产生了缓冲保护，避免受损；具体地，缸体套41上设有润滑孔411，可用于安装滚珠，保证传动活塞24的顺畅移动。
在其中一个实施方式中，主壳组件30包括基壳31、连接基壳31的手柄32、及扣合在基壳31一侧的侧盖33；驱动支架21连接基壳31内侧；可选地，基壳31内设有电机承托块311，第一底板部211连接电机承托块311；或基壳31内延伸有支柱部312，第二底板部214与支柱部312之间通过螺钉件及胶圈连接固定；具体地，以传动活塞24的中心为轴心，驱动机构可以任意角度设置在主壳组件30中；进一步地，主壳组件30还包括容纳定位环43的装饰盖34、用于支撑控制电路60的支撑座35、及盖合在支撑座35上的面盖36；具体地，定位环43与基壳31一侧通过螺钉件固定连接。
