具体实施方式
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申请技术领域的技术人员通常理解的含义相同；本文中在申请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 本申请；本申请的说明书和权利要求书及上述附图说明中的术语“包括”和“具有”以及它们的任何变形，意图在于覆盖不排他的包含。本申请的说明书和权利要求书或上述附图中的术语“第一”、“第二”等是用于区别不同对象，而不是用于描述特定顺序。
在本文中提及“实施例”意味着，结合实施例描述的特定特征、结构或特性可以包含在本申请的至少一个实施例中。在说明书中的各个位置出现该短语并不一定均是指相同的实施例，也不是与其它实施例互斥的独立的或备选的实施例。本领域技术人员显式地和隐式地理解的是，本文所描述的实施例可以与其它实施例相结合。
图1是本发明中所涉及的伸缩机构100的结构示意图；图2是本发明中所涉及的伸缩机构100的第一视角的爆炸图；图3是本发明中所涉及的伸缩机构100的第二视角的爆炸图。
如图1至图3所示，本发明较佳实施例提供的一种伸缩机构100，其包括:壳体10、移动件20和驱动组件30。壳体10围设形成一端开口的容置空间14，驱动组件30位于容置空间14内并用于驱动移动件20往复移动。
在本实施例中，壳体10包括上壳11和下壳12，上壳11和下壳12通过卡接或螺丝紧固以形成用于容纳零部件的容置空间14，且容置空间14的一端具有开口。上壳11的内壁设有导向部，优选地，该导向部可以是导向孔111，且导向孔111朝容置空间14的开口延伸。导向孔111内可以设有套筒13，套筒13可以由金属制成，优选地，套筒13可以由铜合金制成。导向孔111的数量可以是两个，且两个导向孔111的轴线平行。
在本实施例中，移动件20设有连接部22和收容部21，收容部21具有收容槽211，连接部22与收容部21的背向收容槽211的一端连接。收 容部21可以大致呈碗状，收容槽211可以具有大致呈球面的槽底，从而能够更方便容纳和定位与之配合的零部件。导向轴23的一端与移动件20固定连接，导向轴23穿过装在导向孔111内的套筒13。套筒13能够减少导向轴23受到的摩擦力。在另一些示例中，也可以在导向孔111内设置直线轴承或滑动轴承以减少摩擦力。导向轴23可以由金属制成，优选地，导向轴23可以由钢制成。导向轴23的数量可以是两个，且两个导向轴23的轴线平行。由此，移动件20能够沿着导向孔111的延伸方向移动。可以理解的是，导向孔111和导向轴23的数量也可以大于二，而且沿着导向轴23的轴线方向可以设置更多的导向孔111以提高导向精度。
图4是本发明中所涉及的传动部件32的安装的爆炸图。
在本实施例中，驱动组件30包括驱动器31、与驱动器31连接的传动部件32和用于安装传动部件32的安装件33。驱动器31可以是电机31A。传动部件32包括第一齿轮321、第二齿轮322、第三齿轮323、第四齿轮324、蜗杆325、蜗轮326、转动件327和连杆328。安装件33包括箱体331和箱盖332，箱体331和箱盖332通过卡接或螺丝紧固以形成用于容纳传动零部件的收容空间。箱体331与上壳11固定连接。如图4所示，电机31A固定在箱体331上，电机31A的转轴与蜗杆325固定连接。蜗轮326与第一齿轮321共同固定于第一转轴341上，第二齿轮322与第四齿轮324共同固定于第二转轴342上，第三齿轮323与转动件327共同固定于第三转轴343上。第一转轴341、第二转轴342和第三转轴343的两端均分别通过轴承安装于箱体331和箱盖332上。蜗杆325与蜗轮326啮合，第一齿轮321与第二齿轮322啮合，第四齿轮324与第三齿轮323啮合。由此，电机31A能够依次通过蜗杆325、蜗轮326、第一齿轮321、第二齿轮322、第四齿轮324和第三齿轮323驱动转动件327旋转。 此外，第一齿轮321的齿数少于第二齿轮322的齿数，第四齿轮324的齿数少于第三齿轮323的齿数。由此，蜗杆325、蜗轮326、第一齿轮321、第二齿轮322、第三齿轮323和第四齿轮324能够组成减速传动机构，有助于提高对转动件327的驱动力和旋转精度，从而能够提高移动件20的移动可靠性和移动精度。第一齿轮321、第二齿轮322、第三齿轮323、第四齿轮324、蜗杆325和蜗轮326设置在由箱体331和箱盖332构成的收容空间内，有助于保护这些传动零部件，避免与其它零部件相互干扰。在另一些示例中，也可以不需要安装件33，而将电机31A、蜗轮326和齿轮直接安装于壳体10。在本实施例中，电机31A的转轴的轴线与导向孔111的延伸方向平行，有助于减小伸缩机构100的横向尺寸，有利于对伸缩机构100的握持。
在本实施例中，第三齿轮323与转动件327共同固定于第三转轴343上。第三转轴343的轴线与导向孔111的轴线相互垂直。转动件327设有铰接部361，铰接部361可以呈轴状并且与第三转轴343间隔一定距离。连杆328具有近端和远端，近端与铰接部361可转动地连接，且近端的旋转轴线与第三转轴343的旋转轴线平行，远端与移动件20的连接部22可转动地连接，且远端的旋转轴线与近端的旋转轴线平行。转动件327和连杆328可以构成曲柄连杆传动机构。由此，电机31A能够通过传动部件32驱动移动件20沿着导向孔111的延伸方向移动。连杆328与转动件327的铰接部361通过第一轴承351连接，连杆328与移动件20的连接部22通过第二轴承352连接。第一轴承351和第二轴承352可以是关节轴承或者深沟球轴承。优选地，第一轴承351和第二轴承352中的至少一个是关节轴承。进一步地，第一轴承351和第二轴承352均是关节轴承。第一轴承351和第二轴承352选用关节轴承，可以允许连杆328的两 端在旋转的同时，沿旋转轴线的方向有一定范围的偏转，以避免在运动过程中卡滞或卡死。由此，能够令移动件20的运动更加顺畅。
在本实施例中，伸缩机构100还可以包括电池(未图示)和开关(未图示)。电池可以设在壳体10的容置空间14内，开关可以设在壳体10的外表面。可以理解的是，电池和开关的设置是本领域的常规技术，在此不做进一步的描述。
图5是本发明中所涉及的按摩器1的结构示意图；图6是本发明中所涉及的按摩器1的爆炸图；图7是本发明中所涉及的按摩器1的剖视图。
在本实施例中，如图2、图5至图7所示，伸缩机构100可以应用到按摩器1中。按摩器1可以主要包括伸缩机构100和按摩件40，按摩件40与伸缩机构100的移动件20连接，在移动件20的推动下，按摩件40能够往复移动或者称之为伸缩运动。移动件20设有连接部22和第一卡接部201，按摩件40设有第二卡接部401，移动件20和按摩件40通过第一卡接部201和第二卡接部401的配合可拆卸地连接，传动部件32与连接部22连接。如前文所述，移动件20设有收容部21，收容部21具有收容槽211，收容部21可以大致呈碗状，收容槽211可以具有大致呈球面的槽底。第一卡接部201设于收容槽211内。按摩件40位于收容槽211内并且与收容部21可拆卸地连接，按摩件40用于按摩皮肤、肌肉或其他人体组织。按摩件40可以由橡胶制成，优选地，按摩件40可以由硅胶制成。按摩件40可以依据按摩需求设定为任何形状，本申请不对按摩件40或伸缩机构100的适用范围做进一步的限定。在一些示例中，按摩件40可以呈手指状，按摩器1可以包括一个或多个伸缩机构100及按摩件40，按摩器1可以用于按摩肩部或背部。按摩器1还可以包括套在壳体10的外表面上的保护套(未图示)，保护套可以由硅胶制成，保护套可以用于改善按摩器1的握持的舒适度和保护按摩器1的零部件。
在本实施例中，按摩件40包括按摩部43和支架41，按摩部43设有沿其轴线延伸的内腔431，支架41从按摩部43的一端嵌入按摩部43的腔壁中，支架41的一端于收容槽211内与收容部21卡接。支架41对按摩部43起支撑和加强作用。第二卡接部401设于支架41的一端并自按摩件40的一端露出，支架41通过第一卡接部201和第二卡接部401的卡接固定于收容槽211内。第一卡接部201包括自收容槽211的底部凸伸出的第一凸台212和设于第一凸台212外壁上的卡接柱213，支架41包括基部418，第二卡接部401设于基部418，其包括第二凸台417、设于第二凸台417上的套接槽414以及设于套接槽414内壁上的卡槽，卡槽可以是“L”形槽415，套接槽414套设于第一凸台212、卡槽与卡接柱213卡接，以将支架41卡固于收容槽211内。支架41还包括设于基部418的远离第二卡接部401的一端的多个弹性部412，多个弹性部412等间隔设置，弹性部412上设有多个通孔，即网孔413。弹性部412的作用一是支撑按摩部43，另一个是增加径向弹性，即扩张与收缩。通孔用于增加按摩部43与支架41连接的稳固性。具体地，支架41呈圆形壳体状，支架41设有沿着远离收容部21的方向延伸的三个弹性部412，三个弹性部412在支架41的壳壁所在的圆周上均匀分布。优选地，三个弹性部412上设有多个网孔413。支架41可以由具有一定弹性的金属或塑料制成。在支架41的支撑下，按摩件40具有一定弹性和强度，从而能够提高按摩件40的按摩效果和使用寿命。优选地，按摩部43和支架41的材料分别为硅胶和金属。在一些示例中，按摩部43和支架41为注塑一体成型。
图8是本发明中所涉及的收容部21的结构示意图；图9是本发明中所涉及的支架41的结构示意图。
在本实施例中，按摩件40通过支架41与收容部21连接，支架41的一端于收容槽211内与收容部21卡接。按摩部43具有内腔431，内腔431的一端开口，另一端设有过孔416，基部418设有与套接槽414连通的贯通孔，过孔416和贯通孔连通。具体地，收容槽211的底部设有第一凸台212，第一凸台212的外圆周面上设有两个对称分布的卡 接柱213，支架41的靠近收容部21的一端沿轴向方向设有套接槽414，第一凸台212与套接槽414间隙配合，套接槽414的内壁上设有两个关于套接槽414的轴线中心对称的“L”形槽415，“L”形槽415用于容纳卡接柱213以实现支架41与收容部21的卡接。“L”形槽415的槽宽可以比卡接柱213的外径略大，槽深可以比卡接柱213的高度略大。在安装时，将“L”形槽415的竖向槽部的槽口对准卡接柱213并插入以使卡接柱213到达“L”形槽415的横向槽部，然后旋转按摩件40使卡接柱213离开竖向槽部以实现卡接。
在本实施例中，按摩器1还可以包括密封件，密封件可以是胶塞42，支架41的靠近收容部21的一端设有与按摩部43的内腔431连通的过孔416，胶塞42与支架41卡接并堵塞过孔416。胶塞42可以避免外物通过按摩部43的内腔431接触伸缩机构100而影响伸缩机构100的运动部件的工作。
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。
