Description

健身器材的阻力感测机构
技术领域
本发明与健身器材有关,特别是指一种健身器材的阻力感测机构。
背景技术
一般的健身器材为了让用户可以根据自身的训练需求来调整操作难易度,在结构上通常会配置一阻力调整器,让使用者能够透过阻力调整器对飞轮或其他类似的元件施加不同程度的阻力,在调整阻力的同时,为了让使用者能够确实掌握阻力调整器所施加的阻力大小,有一部分的健身器材会再配置一感测装置,主要是用来对阻力调整器所施加的阻力大小进行感测,以便让使用者能够随时视情况作调整。
就与感测装置相关的先前技术来说,台湾公告第M435942号专利案所公开的扭力感测装置主要是将主感测元件与被感测元件分别设置于固定件与位置调整件上,通过旋转调整杆即能改变位置调整件与固定件之间的相对距离,使主感测元件因与被感测元件之间的距离改变而产生相对应的感测信号。然而在前述专利案中,被感测元件是保持固定不动,所以在只有主感测元件可以移动的情况下,整个过程需要耗费比较长的时间才能够完成感测,如此在实际操作时容易造成使用者的不便。
发明内容
本发明的主要目的在于提供一种健身器材的阻力感测机构,其能减少作动行程及缩短感测时间,进而增加操作上的便利性。
为了达成上述目的,本发明所提供的阻力感测机构包括一阻力调整单元及一感测单元。该阻力调整单元具有一调整座、一固定套管、一调整杆与一第一螺帽,该调整座设于一飞轮的周缘且该调整座的一端枢设于一车架,该固定套管设于该车架且位于该调整座的上方,该调整杆可原地转动地穿设于该固定套管且具有一第一螺纹段与一第二螺纹段,该第一、第二螺纹段具有相反的旋向,该第一螺帽枢设于该调整座且螺接于该调整杆之第一螺纹段,使得该第一螺帽能通过该调整杆的驱动而带动该调整座相对该飞轮上下偏转;该感测单元具有一连动座、一第二螺帽、一感测元件,以及一被感测元件,该连动座的一端枢设于该调整座,该第二螺帽螺设于该阻力调整单元的调整杆的第二螺纹段且枢设于该连动座,使得该第二螺帽能通过该调整杆的驱动而带动该该连动座相对于该调整座上下偏转,该感测元件设于该调整座与该连动座的其中之一,该被感测元件设于该调整座与该连动座的另外之一,而且,该感测元件与该被感测元件之间相互对应。
由上述可知,本发明的阻力感测机构利用不同旋向的第一、第二螺纹段,使该调整座与该连动座可以利用该第一、第二螺帽的相对运动而改变该感测元件与该被感测元件之间的距离,进而让该感测元件输出相对应的感测信号,如此即能达到减少作动行程及缩短感测时间的效果。

具体实施方式
为使本发明的目的、技术方案和优点更加清楚明白,以下结合具体实施例,并参照附图,对本发明进一步详细说明。
请先参阅图1,图中所示的健身器材包括一车架12与一可转动地设于车架12的飞轮14。本发明的阻力感测机构10包括一阻力调整单元30及一感测单元40。
阻力调整单元30具有一调整座31、二相对的磁性件32、一固定套管33、一调整杆34,以及一第一螺帽35。调整座31的后端枢设于车架12,调整座31的两相对侧面分别贯穿有一长条孔312;磁性件32设于调整座31的内侧面,并且与飞轮14保持一预定距离;固定套管33固定于车架12且位于调整座31的上方;调整杆34具有一旋钮342与一连接旋钮342的螺杆344,螺杆部344可原地转动地穿设于固定套管33内且具有一第一螺纹段S1与一第二螺纹部S2,第一、第二螺纹段S1、S2具有相反的旋向;第一螺帽35螺设于调整杆34的螺杆部344的第一螺纹段S1,而且,第一螺帽35的两相对侧面分别通过一第一枢轴P1枢设于调整座31的中间位置,第一枢轴P1可位移地穿设于调整座31的长条孔312内。
感测单元40具有一连动座41与一第二螺帽42,连动座41的后端与调整座31的后端是以同轴方式枢设于车架12,第二螺帽42螺设于调整杆34的螺杆部344的第二螺纹段S2,而且,第二螺帽42的两相对侧面分别通过一第二枢轴P2枢设于连动座41的中间位置。此外,感测单元40还具有一感测元件43与一被感测元件44,感测元件43设置于调整座31的顶面与连动座41的底面的其中一个位置,被感测元件44设置于调整座31的顶面与连动座41的底面的另外一个位置,也就是说,假如感测元件43是设置在调整座31的顶面,被感测元件44就设置在连动座41的底面,如果感测元件43设置在连动座41的底面,被感测元件44设置在调整座31的顶面,然而不论以前述哪种方式设置,感测元件43与被感测元件44之间必须要相互对应。
由上述可知,如图2及图3所示,当利用旋钮342转动调整杆34时,调整杆34会经由螺杆部344的第一、第二螺纹段S1、S2分别驱动第一螺帽35及第二螺帽42沿着调整杆34的轴向上下位移,在第一螺帽35的位移过程中,第一螺帽35会带动调整座31相对飞轮14偏转,使调整座31在相对飞轮14偏转时能利用两个磁性件32之间的磁通量变化对飞轮14提供阻力效果,另外,在第二螺帽42的位移过程中,第二螺帽42会带动连动座41相对调整座31偏转。由于第一、第二螺纹段S1、S2具有相反的旋向,所以第一、第二螺帽35、42在受到调整杆34的驱动之下会朝彼此靠近或远离,因此调整座31与连动座42会分别跟着第一、第二螺帽35、42朝彼此靠近或远离,如此一来,感测元件43与被感测元件44之间即可利用调整座31与连动座42的相对作动来改变彼此之间的距离,一旦两者之间的距离有所改变,感测元件43便能产生相对应的感测信号至一控制面板(图中所示),使用者便能根据控制面板所显示的信息得知阻力的变化。
综上所陈,本发明的阻力感测机构20利用不同旋向的第一、第二螺纹段S1、S2,使调整座31与连动座42可以利用第一、第二螺帽35、42的相对运动来改变感测元件43与被感测元件44之间的距离,并非只有单方作动,因此与习用技术相比之下,本发明可以有效达到减少作动行程及缩短感测时间的效果。
以上所述的具体实施例,对本发明的目的、技术方案和有益效果进行了进一步详细说明,所应理解的是,以上所述仅为本发明的具体实施例而已,并不用于限制本发明,凡在本发明的精神和原则之内,所做的任何修改、等同替换、改进等,均应包含在本发明的保护范围之内。
