具体的,在本实施例中,刹车件96为刹车脚踏。在申请的其他较佳实施中,该刹车件96还可以为刹车车把。通过刹车装置90的设置,从而实现了刹车操作,同时该刹车装置90还可以实现换向操作。例如,当两车轮11同时正向旋转时,在脚踏装置20处于最高点与最低点之前,可踏动其中一侧的刹车件96,使得该侧的驱动摩擦块92与该侧的车轮摩擦块91分离,并利用身体扭动车身10使得该侧车轮11由于惯性朝着与原旋转方向相反的方向旋转(即该车轮11开始反向旋转),从而带动第一摩擦件55反向摆动,进而使得第一触动组53反向摆动,第二触动组54正向摆动,第一正向棘爪422与第二正向棘爪432被打开,当松开刹车件96时,该侧的车轮11变为反向旋转,从而改变了该车轮11的旋转方向。当同时踏动两侧的刹车件96,可使得两侧的车轮11的旋转方向均改变,从而实现了换向操作。而如果仅踏动其中一侧的刹车件96,则另一侧的车轮11依然保持原来的正向旋转,因此使得两个车轮11的旋转方向相反,从而实现了原地旋转。
进一步地,请一并参阅图1至图3,作为本申请第一实施例提供的平衡车的一种具体实施方式,该脚踏装置20包括滑块23以及安装于滑块23上的脚踏24,该车身10上设置有滑轨座12,该滑块23滑动安装于滑轨座12上,从而使得运行更加平稳。

单个车轮11的持续前进工作原理如下所示:
当车轮11正向旋转时,此时第一触动组53处于正向摆动,第二触动组54处于反向摆动,此时第一反向棘爪触动臂531与第一反向棘爪423正对,第二正向棘爪触动臂532与第二正向棘爪432彼此错开,且第二反向棘爪触动臂542与第二反向棘爪433正对,第一正向棘爪触动臂541与第一正向棘爪422彼此错开。由于在最高点第一反向棘爪触动臂531会打开第一反向棘爪423,使得第一反向棘爪423与第一双向棘齿4211分离,而第二正向棘爪432与第二反向棘爪433保持闭合状态,当脚踏装置20由最高点向下运动时,第一棘轮421反向空旋,第一双向棘齿4211越过第一反向棘爪423并随着第一棘轮421同步反向旋转,而第二正向棘爪432与第二反向棘爪433同时与第二双向棘齿4311配合锁紧第二棘轮431,从而使得第二棘轮431驱动传动链条413正向旋转,实现车轮11的正向旋转。
当脚踏装置20运动到最低点时,此时第二反向棘爪触动臂542打开第二反向棘爪433,使得第二反向棘爪433与第二双向棘齿4311分离,而此时第一双向棘齿4211刚好旋转并越过第一正向棘爪触动臂541回到初始位置,此时第一正向棘爪422与第一反向棘爪423保持闭合状态,当脚踏装置20由最低点向上运动时,第二棘轮431反向空旋,第二双向棘齿4311越过第二反向棘爪433并随第二棘轮431同步反向旋转,而第一正向棘爪422与第一反向棘爪423同时与第一双向棘齿4211配合从而锁紧第一棘轮421,使得第一棘轮421驱动传动链条413正向旋转,实现车轮11的正向旋转,从而完成单个车轮11的正向交替过程,使得车轮11持续前进。同理,单个车轮11的反向交替过程同理亦可实现,在此不再赘述。
单个车轮11的换向原理如下所示:
当第二棘轮431处于工作状态(即第二棘轮431驱动传动链条413旋转)时,此时第一棘轮421处于空旋状态(即第一棘轮421不会驱动链条旋转),若同侧的脚踏装置20向下运动,此时第二棘轮431同步向下运动,该第二棘轮431驱动传动链条413正向旋转,实现车轮11的正向旋转,若同侧的脚踏装置20向上运动,此时第二棘轮431同步向上运动,该第二棘轮431驱动传动链条413反向旋转,进而实现车轮11的反向旋转。

例如,当车轮11需要由前进改为后退时,可通过将拨线器71拨动到反向档位,摆杆571带动第三触动组58反向摆动,此时,第一触动件582与第一导杆4251正对,第一触动件582与第二导杆4252彼此错开,实现了第三反向棘爪425在最高点时的强制打开操作;第二触动件583与第五导杆4241正对,第二触动件583与第六导杆4242彼此错开,实现了第三正向棘爪424在最高点时的强制打开操作;第四触动件585与第九导杆4341正对,第四触动件585与第十导杆4342错开,实现了第四正向棘爪434在最高点时的强制闭合操作;第三触动件584与第十三导杆4351正对,第三触动件584与第十四导杆4352错开,实现了第四反向棘爪435在最高点时的强制闭合操作,从而使得当脚踏装置20向下运动时,第四正向棘爪434与第四反向棘爪435同时与传动链条413抵接以锁紧传动链条413,并带动传动链条413反向旋转。且此时第五触动件592与第三导杆4253正对,第五触动件592与第四导杆4254彼此错开,实现了第三反向棘爪425在最低点时的强制闭合操作;第六触动件593与第七导杆4243正对,第六触动件593与第八导杆4244错开,实现了第三正向棘爪424在最低点时的强制闭合操作;第八触动件595与第十一导杆4343正对,第八触动件595与第十二导杆4344彼此错开,实现了第四正向棘爪434在最低点时的强制打开操作;第七触动件594与第十五导杆4353正对,第七触动件594与第十六导杆4354彼此错开,实现了第四反向棘爪435在最低点时的强制打开操作,从而使得当脚踏装置20向上运动时,第三正向棘爪424与第三反向棘爪425同时与传动链条413抵接以锁紧传动链条413,并带动传动链条413反向旋转,避免受到车轮11的旋转方向干涉。同理,当车轮11需要由后退改为前进时,其操作与前进改为后退的操作相反,在此不再赘述。通过手动换挡机构70的设置,实现手动切换该车轮11的正向旋转或者反向旋转。
进一步地,作为本申请第二实施例提供的平衡车的一种具体实施方式,第三正向棘爪424、第三反向棘爪425、第四正向棘爪434以及第四反向棘爪435均为摩擦棘爪,该传动链条413与第三正向棘爪424、第三反向棘爪425、第四正向棘爪434以及第四反向棘爪435接触的面为摩擦面,通过相互之间的摩擦力带动传动链条413旋转。应当说明的是,第三正向棘爪424、第三反向棘爪425、第四正向棘爪434以及第四反向棘爪435的设置方式并不局限于此,例如,在本申请的其他较佳实施例中,第三正向棘爪424、第三反向棘爪425、第四正向棘爪434以及第四反向棘爪435还可以为多齿棘爪,传动链条413为多齿式传动链条413,通过多齿棘爪与多齿式传动链条413的配合作用,使得传动更加精密准确。

当第三反向棘爪425与第三正向棘爪424处于工作状态(即第三反向棘爪425与第三正向棘爪424驱动传动链条413旋转)时,此时第四正向棘爪434与第四反向棘爪435处于打开状态(即第四正向棘爪434与第四反向棘爪435不会驱动链条旋转);若同侧的脚踏装置20向下运动,此时第三反向棘爪425与第三正向棘爪424同步向下运动,第三反向棘爪425与第三正向棘爪424同时与传动链条413抵接以锁紧传动链条413,并带动传动链条413正向旋转,实现车轮11的正向旋转;若同侧的脚踏装置20向上运动,此时第三反向棘爪425与第三正向棘爪424同步向上运动,该第三反向棘爪425与第三正向棘爪424驱动传动链条413反向旋转,进而实现车轮11的反向旋转。
当第四正向棘爪434与第四反向棘爪435处于工作状态(即第四正向棘爪434与第四反向棘爪435驱动传动链条413旋转)时,此时第三反向棘爪425与第三正向棘爪424处于打开状态(即第三反向棘爪425与第三正向棘爪424不会驱动链条旋转),若同侧的脚踏装置20向下运动,此时第四正向棘爪434与第四反向棘爪435同步向下运动,该第四正向棘爪434与第四反向棘爪435驱动传动链条413反向旋转,实现车轮11的反向旋转,若同侧的脚踏装置20向上运动,此时第四正向棘爪434与第四反向棘爪435同步向上运动,该第四正向棘爪434与第四反向棘爪435驱动传动链条413正向旋转,进而实现车轮11的正向旋转。
