The driving mechanism 15 is reversed to drive the lifting drive wheel assembly 6 to rotate in the opposite direction. During the reverse rotation, the one-way bearing 6b reels in the traction rope 7, and the traction rope 7 forces the bracket assembly 3 to overcome the resistance of the elastic element 4 and slide downward, thereby retracting the massage head 2 into the backrest.
在本实施例中,两组按摩器A的第一主动轮8a和第二主动轮8b均位于同一直线上,且都固套在同一根转轴14上。In this embodiment, the first driving wheels 8a and the second driving wheels 8b of the two massagers A are located on the same straight line and are fixedly sleeved on the same rotating shaft 14.
再如图6所示,为了保证按摩头2既能够沿旋转驱动轮5的轴向升降运动,又能够随旋转驱动轮5同步转动,本实施例提供了一种按摩头2与旋转驱动轮5之间的装配结构,具体为:As shown in FIG. 6 , in order to ensure that the massage head 2 can move up and down along the axial direction of the rotating driving wheel 5 and can rotate synchronously with the rotating driving wheel 5, this embodiment provides an assembly structure between the massage head 2 and the rotating driving wheel 5, specifically:
旋转驱动轮5具有第一中心通孔5a,第一中心通孔5a内可上下滑动地装配有过渡套9,过渡套9具有第二中心通孔9a,按摩头2下端的连接柱2a可上下滑动地滑动装配在第二中心通孔9a内。此结构布局能够保证按摩头2沿旋转驱动轮5的轴向升降运动。The rotating drive wheel 5 has a first central through hole 5a, in which a transition sleeve 9 is slidably mounted, and the transition sleeve 9 has a second central through hole 9a, in which a connecting column 2a at the lower end of the massage head 2 is slidably mounted. This structural layout can ensure that the massage head 2 can move up and down along the axial direction of the rotating drive wheel 5.
第一中心通孔5a的孔壁上设有第一导向槽5b,过渡套9下端设有向外延伸的第一定位块9b,第一定位块9b可上下滑动地连接在第一导向槽5b内,第二中心通孔9a的孔壁上设有第二导向槽9c,连接柱2a的下端设有向外延伸的第二定位块2b,第二定位块2b可上下滑动地连接在所述第二导向槽9c内。此结构布局能够保证按摩头2随旋转驱动轮5同步转动。A first guide groove 5b is provided on the hole wall of the first central through hole 5a, a first positioning block 9b extending outward is provided at the lower end of the transition sleeve 9, and the first positioning block 9b is connected to the first guide groove 5b slidably up and down, a second guide groove 9c is provided on the hole wall of the second central through hole 9a, and a second positioning block 2b extending outward is provided at the lower end of the connecting column 2a, and the second positioning block 2b is connected to the second guide groove 9c slidably up and down. This structural layout can ensure that the massage head 2 rotates synchronously with the rotating driving wheel 5.
如图5所示,单向轴承6b和升降驱动轮6a同轴安装的具体安装结构为:安装基体1内转动设置有装配轴11,升降驱动轮6a固定套装在装配轴11的上部,单向轴承6b的内圈a固定套装在装配轴11的下部。As shown in Figure 5, the specific installation structure of the coaxial installation of the one-way bearing 6b and the lifting drive wheel 6a is: an assembly shaft 11 is rotatably arranged in the installation base 1, the lifting drive wheel 6a is fixedly sleeved on the upper part of the assembly shaft 11, and the inner ring a of the one-way bearing 6b is fixedly sleeved on the lower part of the assembly shaft 11.
再如图4至7所示,为了方便安装牵引绳7,单向轴承6b的外圈b固定套装有装配环12,装配环12的侧壁上设有向外凸出的安装部12a,安装部12a上设有挂槽12b,牵引绳7的一端连接在该挂槽12b上;进一步的,一级导向柱3d内部具有安装孔3e,牵引绳7的另一端穿过一级升降通道1b后,再伸入并固定在安装孔3e内。在卷收牵引绳7时,为了使牵引绳7能够更稳固的缠绕在装配环12上,在装配环12的侧壁上设有自挂槽12b向外延伸的定位槽12c。As shown in Figures 4 to 7, in order to facilitate the installation of the traction rope 7, the outer ring b of the one-way bearing 6b is fixedly sleeved with an assembly ring 12, and a mounting portion 12a protruding outward is provided on the side wall of the assembly ring 12, and a hanging groove 12b is provided on the mounting portion 12a, and one end of the traction rope 7 is connected to the hanging groove 12b; further, a mounting hole 3e is provided inside the primary guide column 3d, and the other end of the traction rope 7 passes through the primary lifting channel 1b and then extends into and is fixed in the mounting hole 3e. When the traction rope 7 is reeled in, in order to make the traction rope 7 more firmly wound around the assembly ring 12, a positioning groove 12c extending outward from the hanging groove 12b is provided on the side wall of the assembly ring 12.
如图4、8所示,为了保证牵引绳7能够更便捷的装配至一级升降通道1b和安装孔3e内,在对应一级升降通道1b下端的位置设有导向轮1c,牵引绳7滑动支撑在导向轮1c上。更进一步的,为便于固定牵引绳7的中部,安装基体1的底部分布有与牵引绳7相适应的导向卡槽1e。As shown in Figs. 4 and 8, in order to ensure that the traction rope 7 can be more conveniently assembled into the primary lifting channel 1b and the mounting hole 3e, a guide wheel 1c is provided at the position corresponding to the lower end of the primary lifting channel 1b, and the traction rope 7 is slidably supported on the guide wheel 1c. Furthermore, in order to facilitate fixing the middle part of the traction rope 7, a guide slot 1e adapted to the traction rope 7 is distributed at the bottom of the mounting base 1.
为了使升降运动更平稳,托盘3b的周向设置有三根一级导向柱3d,并且其中两根一级导向柱3d与装配环12之间均连接有牵引绳7。In order to make the lifting movement smoother, three primary guide columns 3d are arranged around the tray 3b, and traction ropes 7 are connected between two of the primary guide columns 3d and the assembly ring 12.
如图8所示,安装基体1内设有弧形槽1d,安装部12a的活动范围位于弧形槽1d内,弧形槽1d的第一端部c和第二端部d能够限制装配环12的转动范围。托盘3b上升至最高位置时,装配环12的安装部12a抵靠在第二端部d上,能够防止装配环12进一步反转,避免牵引绳7被反向卷收。As shown in Fig. 8, an arc groove 1d is provided in the mounting base 1, and the movable range of the mounting portion 12a is located in the arc groove 1d. The first end c and the second end d of the arc groove 1d can limit the rotation range of the mounting ring 12. When the tray 3b rises to the highest position, the mounting portion 12a of the mounting ring 12 abuts against the second end d, which can prevent the mounting ring 12 from further reversing and prevent the traction rope 7 from being reversely retracted.
在本实施例中,第一主动轮8a与升降驱动轮6a之间为涡轮蜗杆啮合关系,第二主动轮8b与旋转驱动轮5之间为斜齿啮合关系。In this embodiment, the first driving wheel 8a and the lifting driving wheel 6a are in a worm gear meshing relationship, and the second driving wheel 8b and the rotating driving wheel 5 are in a helical gear meshing relationship.
超薄型机械式按摩装置的工作原理如下:The working principle of the ultra-thin mechanical massage device is as follows:
1、按摩装置关闭状态下,按摩头2处于最低位置,此时在单向轴承6b自锁的作用下,牵引绳7部分被卷收在装配环12上。1. When the massage device is closed, the massage head 2 is at the lowest position. At this time, due to the self-locking effect of the one-way bearing 6b, part of the traction rope 7 is rolled up on the assembly ring 12.
2、用户需要使用腰部功能时,驱动机构15正向工作带动转轴14转动,转轴14带动升降驱动轮6a逆时针转动,使得单向轴承6b自锁力被释放,即牵引绳7的保持力被释放,此时,弹性元件4的推力即可驱动托盘3b上升,从而使按摩头2上升至用户腰部位置。与此同时,转轴14经第二主动轮8b和旋转驱动轮5驱动按摩头2转动,从而实现腰部按摩。2. When the user needs to use the waist massage function, the driving mechanism 15 works forward to drive the rotating shaft 14 to rotate, and the rotating shaft 14 drives the lifting driving wheel 6a to rotate counterclockwise, so that the self-locking force of the one-way bearing 6b is released, that is, the holding force of the traction rope 7 is released. At this time, the thrust of the elastic element 4 can drive the tray 3b to rise, so that the massage head 2 rises to the user's waist position. At the same time, the rotating shaft 14 drives the massage head 2 to rotate through the second active wheel 8b and the rotating driving wheel 5, thereby achieving waist massage.
3、用户需要关闭腰部功能时,驱动机构15反向工作带动转轴14反转,转轴14反转则会带动升降驱动轮6a、单向轴承6b的外圈b以及装配环12同步顺时针转动,使得牵引绳7被卷收在装配环12上,牵引绳7被卷收的过程即可拖拽托架组件3向下运动,从而将按摩头2收回至最低位置。3. When the user needs to turn off the waist function, the driving mechanism 15 works in the reverse direction to drive the rotating shaft 14 to reverse. The reverse rotation of the rotating shaft 14 will drive the lifting driving wheel 6a, the outer ring b of the one-way bearing 6b and the assembly ring 12 to rotate clockwise synchronously, so that the traction rope 7 is wound on the assembly ring 12. The process of the traction rope 7 being wound can drag the bracket assembly 3 downward, thereby retracting the massage head 2 to the lowest position.
