本申请提供的脚踏平衡车,与现有技术相比,利用第一脚踏3与第二脚踏4上下往复摆动提供的驱动力,通过反向传动机构5、第一棘轮传动机构6与第二棘轮传动机构7的配合作用驱动车轮2的正向旋转或者反向旋转,只需要交替踏动第一脚踏3与第二脚踏4,即可实现车轮2的持续前进或者后退,且通过换向机构8的设置,使得车轮2可以在行进过程中随时可改变旋转方向,更有利于保持平衡,有效解决现有技术由于采用电动平衡车导致结构复杂、成本较高的问题,且结构十分简单,传动无死点,蹬车省时省力,有效提高了平衡车的速度以及舒适感;另外,通过第一脚踏3以及第二脚踏4的交替踏动,可适当降低第一脚踏3以及第二脚踏4的摆动幅度,使双脚在遇到突发情况能更早着地支撑,并提供安全直立驱动条件。
进一步地,请一并参阅图1至图2,作为本申请第一实施例提供的脚踏平衡车的一种具体实施方式,反向传动机构5包括第一传动轮51、与第一传动轮51同轴安装的第二传动轮52、连接第一传动轮51与第二传动轮52的第一传动带53以及用于支撑第一传动带53的第一换向轮54,第一传动带53的一端与第一脚踏3连接固定,另一端与第二脚踏4连接固定,通过该反向传动机构5的设置,可以实现第一脚踏3与第二脚踏4的反向摆动。优选的,在本实施例中,该第一传动轮51、第二传动轮52为齿轮,该第一传动带53为链条。应当说明的是,该反向传动机构5的设置方式并不局限于此,例如,如图15所示,在本申请的第二实施中,该第一传动带53还可以为绳索,该第一传动轮51、第二传动轮52还可以为用于固定绳索的绳索轮,其同样可以实现第一脚踏3与第二脚踏4的反向摆动。
进一步地,请一并参阅图3至图4,作为本申请第一实施例提供的脚踏平衡车的一种具体实施方式,第一棘轮传动机构6包括第一棘轮61、第一正向棘爪62以及第一反向棘爪63。该第一棘轮61用于驱动车轮2旋转,第一正向棘爪62转动安装于第一传动轮51上并用于驱动第一棘轮61正向旋转,第一反向棘爪63转动安装于第一传动轮51上并用于驱动第一棘轮61反向旋转,通过第一棘轮61、第一正向棘爪62以及第一反向棘爪63的配合作用,从而可以驱动车轮2的正向旋转或者反向旋转。第二棘轮传动机构7包括第二棘轮71、第二正向棘爪72以及第二反向棘爪73。第二棘轮71与所述第一棘轮61同轴固定并用于驱动车轮2旋转,第二正向棘爪72转动安装于第二传动轮52上并用于驱动第二棘轮71正向旋转,第二反向棘爪73转动安装于第二传动轮52上并用于驱动第二棘轮71反向旋转,通过第二棘轮71、第二正向棘爪72以及第二反向棘爪73的配合作用,可以驱动车轮2的正向旋转或者反向旋转。
优选的,如图3及图5所示,在本申请第一实施例中,第一棘轮61上设置有第一正向棘齿611a、第一反向棘齿612a、第二正向棘齿611b以及第二反向棘齿612b,即第一棘轮61上的正向棘齿的数量设置为两个,反向棘齿的数量为两个。第一正向棘爪62与第一正向棘齿611a或者第二正向棘齿611b配合以驱动第一棘轮61正向旋转,第一反向棘爪63与第一反向棘齿612a或者第二反向棘齿612b配合以驱动第一棘轮61反向旋转。如图4及图6所示,第二棘轮71上设置有第三正向棘齿711a、第三反向棘齿712a、第四正向棘齿711b以及第四反向棘齿712b,即第二棘轮71上的正向棘齿的的数量设置为两个,反向棘齿的数量为两个。第二正向棘爪72与第三正向棘齿711a或者第四正向棘齿711b配合以驱动第二棘轮71正向旋转,第二反向棘爪73与第三反向棘齿712a或者第四反向棘齿712b配合以驱动第二棘轮71反向旋转。通过第一正向棘爪62驱动第一棘轮61正向旋转,第一反向棘爪63驱动第一棘轮61反向旋转,第二正向棘爪72驱动第二棘轮71正向旋转,第二反向棘爪73驱动第二棘轮71反向旋转,从而实现车轮2的正向旋转或者反向旋转。具体的,在本实施例中,该车轮2与第一棘轮61、第二棘轮71同轴固定。
应当说明的是,如图5至图7所示,第一棘轮61与第二棘轮71之间的夹角α为第一棘轮61或者第二棘轮71上的相邻同向棘齿之间的夹角β的一半。其中,第一棘轮61与第二棘轮71之间的夹角α指的是以第一棘轮61或者第二棘轮71的转动中心为中心,第一棘轮61与第二棘轮71上相邻两个同向棘齿之间的夹角,即第一棘轮61上的第一正向棘齿611a与第二棘轮71的第三正向棘齿711a之间形成的夹角,或者第一棘轮61上的第第一反向棘齿612a与第二棘轮71上的第三反向棘齿712a之间形成的夹角。第一棘轮61与第二棘轮71之间的夹角α同时为工作角度,即该第一正向棘爪62、第一反向棘爪63、第二正向棘爪72或者第二反向棘爪73由行程最高点运动到行程最低点驱动第一棘轮61或者第二棘轮71转动的角度。第一棘轮61上的相邻同向棘齿之间的夹角β指的是第一棘轮61上的相邻的第一正向棘齿611a与第二正向棘齿611b之间形成的夹角,或者,第一棘轮61上的相邻的第一反向棘齿612a与第二反向棘齿612b之间形成的夹角;或者,第二棘轮71上的相邻的第三正向棘齿711a与第四正向棘齿711b之间形成的夹角,或者,第二棘轮71上的相邻的第三反向棘齿712a与第四反向棘齿712b之间形成的夹角。在第一棘轮61与第二棘轮71中,同一棘轮同向棘齿沿同一棘轮圆周均匀分布,同一棘轮可以设置一组或多组正向棘齿与反向棘齿,每组能同时啮合正向棘爪和反向棘爪的正向棘齿与反向棘齿夹角相同。例如,在本实施中,如图7所示,由于第一棘轮61上的正反双向棘齿与第二棘轮71上的正反双向棘齿的数量均为两个,因此,第一棘轮61或者第二棘轮71上的相邻两个正向棘齿或者相邻两个反向棘齿之间的夹角β为180°,此时夹角α为90°。
当第一正向棘爪62运动到行程最高点时,此时第一反向棘爪63、第二正向棘爪72刚好运动到行程的最低点,且第二反向棘爪73刚好运动到行程最高点。当第一正向棘爪62运动到行程最低点时,此时,第一反向棘爪63、第二正向棘爪72刚好运动到行程最高点,第二反向棘爪73刚好运动到行程最低点,进而使得当反向传动机构5带动第一棘轮61工作时,该反向传动机构5与第二棘轮71无传动作用,即当该第一棘轮61驱动车轮2旋转时,此时第二棘轮71处于空旋状态,该第二棘轮71不会驱动车轮2旋转;当反向传动机构5带动第二棘轮71工作时,该反向传动机构5与第一棘轮61无传动作用,此时第一棘轮61处于空旋状态。

本申请第一实施例的脚踏平衡车的工作原理如下所示:
如图3至图4所示,当第一脚踏3处于行程最高点,由于第一传动带53的带动,第二脚踏4位于行程的最高低点。首先,向下踏动第一脚踏3,通过第一传动带53带动第一传动轮51正向旋转,第二传动轮52反向旋转,此时,第一正向棘爪62通过与第一正向棘齿611a的配合驱动第一棘轮61正向旋转,进而带动车轮2正向旋转。当车轮2正向旋转时,此时第一摩擦片与第二摩擦片由于受到车轮2摩擦力的作用,第一摩擦片带动第一触动组813正向摆动,第二摩擦片带动第二触动组823正向摆动,进而使得第一反向触动件8132处于触动位置,第一正向触动件8131离开触动位置,第二反向触动件8232处于触动位置时,第二正向触动件8231离开触动位置。当第一脚踏3由行程最高点运动到行程最低点时,带动第一传动轮51正向旋转,第二传动轮52反向旋转,如图5及图8所示,第一正向棘爪62随着第一传动轮51正向旋转至行程最低点,且此时第一正向棘爪62同时与第一正向棘齿611a配合驱动第一棘轮61正向旋转,第一反向棘爪63随着第一传动轮51正向旋转到行程最高点。如图6及图9所示,第二正向棘爪72随着第二传动轮52反向旋转到行程最高点,第二反向棘爪73由于在行程最高点时被第二反向触动件8232推动与第二棘轮71分离,该第二反向棘爪73可越过第三反向棘齿712a随着第二传动轮52反向旋转至行程最低点,此时第二棘轮71随着车轮2正向空旋。通过在最高点将第二反向棘爪73与第二棘轮71分离,避免第二反向棘爪73与第二反向棘齿712a配合带动第二棘轮71反向旋转,从而使得当第一棘轮61处于工作状态时,第二棘轮71处于空旋状态,不会与第一棘轮61发生运动干涉。
接着,继续向下踏动第二脚踏4,第二脚踏4由行程最高点运动到行程最低点,通过第一传动带53带动第二传动轮52正向旋转,第一传动轮51反向旋转,如图9及图11所示,此时第二正向棘爪72随着第二传动轮52正向旋转至行程最低点,且此时第二正向棘爪72通过与第四正向棘齿711b的配合驱动第二棘轮71正向旋转,进而带动车轮2正向旋转。第二反向棘爪73随着第二传动轮52正向旋转到行程最高点。如图8及图10所示,第一正向棘爪62随着第一传动轮51反向旋转到行程最高点,第一反向棘爪63由于在行程最高点时被第一反向触动件8132推动与第一棘轮61分离,该第一反向棘爪63可越过第一反向棘齿612a随着第一传动轮51反向旋转至行程最低点,此时,第一棘轮61随着车轮2正向空旋。通过在最高点将第一反向棘爪63与第一棘轮61分离,避免第一反向棘爪63与第一反向棘齿612a配合带动第一棘轮61反向旋转,从而使得当第二棘轮71处于工作状态时,第一棘轮61处于空旋状态,不会与第二棘轮71发生运动干涉。进而完成车轮2前进的一个交替过程,通过反复踏动第一脚踏3与第二脚踏4,实现车轮2的持续前进。反之,车轮2的持续后退同理可实现。
本申请第一实施例的脚踏平衡车的换向操作原理如下所示:
当第一棘轮61处于工作状态时,此时第二棘轮71处于空旋状态,若向下踏动第一脚踏3时,通过第一传动带53带动第一传动轮51正向旋转,此时,第一正向棘爪62通过与第一正向棘齿611a或者第二正向棘齿611b的配合驱动第一棘轮61正向旋转,进而带动车轮2正向旋转;若向下踏动第二脚踏4,通过第一传动带53带动第一传动轮51反向旋转,第一反向棘爪63通过与第一反向棘齿612a或者第二反向棘齿612b的配合驱动第一棘轮61反向旋转,进而带动车轮2的反向旋转。通过踏动不同的脚踏,实现车轮2旋转方向的改变,换向操作十分简单方便。
当第二棘轮71处于工作状态时,此时第一棘轮61处于空旋状态,若向下踏动第二脚踏4时,通过第一传动带53带动第二传动轮52正向旋转,此时,第二正向棘爪72通过与第三正向棘齿711a或者第四正向棘齿711b的配合驱动第二棘轮71正向旋转,进而带动车轮2正向旋转;若向下踏动第一脚踏3,通过第一传动带53带动第二传动轮52反向旋转,第二反向棘爪73通过与第三反向棘齿712a或者第四反向棘齿712b的配合驱动第二棘轮71反向旋转,进而带动车轮2的反向旋转。通过踏动不同的脚踏,实现车轮2旋转方向的改变,换向操作十分简单方便。

本申请第四实施例的脚踏平衡车的持续前进的工作原理如下所示:
当第一脚踏3处于行程最高点,由于第一传动带53的带动,第二脚踏4位于行程的最高低点。首先,向下踏动第一脚踏3,通过第一传动带53带动第一传动轮51正向旋转,第二传动轮52反向旋转,此时,第一正向棘爪62驱动第一棘轮61正向旋转,进而带动车轮2正向旋转。当车轮2正向旋转时,此时第一摩擦片与第二摩擦片由于受到车轮2摩擦力的作用,第一摩擦片带动第一触动组813正向摆动,第二摩擦片带动第二触动组823正向摆动,进而使得:第一正向棘爪正向闭合触动件81331处于触动位置,第一正向棘爪反向打开触动件81332离开触动位置,第一反向棘爪反向闭合触动件81333离开触动位置,第一反向棘爪正向打开触动件81334处于触动位置,第一正向棘爪反向闭合触动件81341离开触动位置,第一正向棘爪正向打开触动件81342处于触动位置,第一反向棘爪正向闭合触动件81343处于触动位置,第一反向棘爪反向打开触动件81344离开触动位置,第二正向棘爪正向闭合触动件82331处于触动位置,第二正向棘爪反向打开触动件82332离开触动位置,第二反向棘爪反向闭合触动件82333离开触动位置,第二反向棘爪正向打开触动件82334处于触动位置,第二正向棘爪反向闭合触动件82341离开触动位置,第二正向棘爪正向打开触动件82342处于触动位置,第二反向棘爪正向闭合触动件82343处于触动位置,第二反向棘爪反向打开触动件82344件离开触动位置。
当第一脚踏3处于行程最高点时,此时第一正向棘爪62位于行程最高点,第一正向棘爪正向闭合触动件81331推动第一正向棘爪62翻转,从而使得第一正向棘爪62与第一棘轮61接触,此时第一反向棘爪63运动至行程最低点,第一反向棘爪正向闭合触动件81343推动第一反向棘爪63翻转,从而使得第一反向棘爪63与第一棘轮61接触,且此时第二正向棘爪72位于行程最低点,第二正向棘爪正向打开触动件82342推动第二正向棘爪72翻转,从而使得第二正向棘爪72与第二棘轮71分离,第二反向棘爪73位于行程最高点,第二反向棘爪正向打开触动件82334推动第二反向棘爪73翻转,从而使得第二反向棘爪73与第二棘轮71分离。通过将第二正向棘爪72与第二反向棘爪73打开,从而使得当第一棘轮61处于工作状态时,第二棘轮71处于空旋状态,不会与第一棘轮61发生运动干涉。
当第一脚踏3向下运动时,该第二脚踏4向上运动,当第一脚踏3运动到行程最低点时,第二脚踏4位于行程的最高点,此时第一正向棘爪62随着第一传动轮51正向旋转至行程最低点,并同时驱动第一棘轮61正向旋转,使得车轮2正向旋转,第一反向棘爪63随着第一传动轮51正向旋转到行程最高点,第二正向棘爪72随着第二传动轮52反向旋转到行程最高点,第二反向棘爪73随着第二传动轮52反向旋转到行程最低点。当第二正向棘爪72运动至行程最高点时,第二正向棘爪正向闭合触动件82331推动第二正向棘爪72翻转,从而使得第二正向棘爪72与第二棘轮71接触,此时第二反向棘爪73运动至行程最低点,第二反向棘爪正向闭合触动件82343推动第二反向棘爪73翻转,从而使得第二反向棘爪73与第二棘轮71接触, 且此时第一正向棘爪62运动至行程最低点,第一正向棘爪正向打开触动件81342推动第一正向棘爪62翻转,从而使得第一正向棘爪62与第一棘轮61分离,第一反向棘爪63运动至行程最高点,第一反向棘爪正向打开触动件81334推动第一反向棘爪63翻转,从而使得第一反向棘爪63与第一棘轮61分离。通过将第一正向棘爪62与第一反向棘爪63打开,从而使得当第二棘轮71处于工作状态时,第一棘轮61处于空旋状态,不会与第二棘轮71发生运动干涉。
接着,继续向下踏动第二脚踏4,通过第一传动带53带动第二传动轮52正向旋转,第一传动轮51反向旋转,此时,第二正向棘爪72随着第二传动轮52正向旋转并同时驱动第二棘轮71正向旋转,使得车轮2正向旋转。当第二脚踏4运动到行程最低点时,第一脚踏3位于行程的最高点,进而完成车轮2前进的一个交替过程,通过反复踏动第一脚踏3与第二脚踏4,实现车轮2的持续前进。反之,车轮2的持续后退同理可实现。
本申请第四实施例的脚踏平衡车的换向操作原理如下所示:
当第一棘轮61处于工作状态时,此时第二棘轮71处于空旋状态,第一正向棘爪62与第一反向棘爪63处于闭合状态(即第一正向棘爪62与第一反向棘爪63分别与第一棘轮61接触),第二正向棘爪72与第二反向棘爪73处于打开状态(即第二正向棘爪72与第二反向棘爪73分别与第二棘轮71分离)。若向下踏动第一脚踏3时,通过第一传动带53带动第一传动轮51正向旋转,此时,第一正向棘爪62驱动第一棘轮61正向旋转,进而带动车轮2正向旋转;若向下踏动第二脚踏4,通过第一传动带53带动第一传动轮51反向旋转,第一反向棘爪63驱动第一棘轮61反向旋转,进而带动车轮2的反向旋转,进而可通过踏动不同的脚踏,实现车轮2旋转方向的改变,换向操作十分简单方便。
当第二棘轮71处于工作状态时,此时第一棘轮61处于空旋状态,第二正向棘爪72与第二反向棘爪73处于闭合状态(即第二正向棘爪72与第二反向棘爪73分别与第二棘轮71接触),第一正向棘爪62与第一反向棘爪63处于打开状态(即第一正向棘爪62与第一反向棘爪63分别与第一棘轮61分离),若向下踏动第二脚踏4时,通过第一传动带53带动第二传动轮52正向旋转,此时,第二正向棘爪72驱动第二棘轮71正向旋转,进而带动车轮2正向旋转;若向下踏动第一脚踏3,通过第一传动带53带动第二传动轮52反向旋转,第二反向棘爪73驱动第二棘轮71反向旋转,进而带动车轮2的反向旋转,进而可通过踏动不同的脚踏,实现车轮2旋转方向的改变,换向操作十分简单方便。
请一并参阅图32至图42,现对本申请第五实施例提供的脚踏平衡车进行说明。本申请第五实施例提供的脚踏平衡车的结构与本申请第一实施例的脚踏平衡车的结构基本相同,其所不同的是:
在本实施中,如图39至图40所示,第一棘轮61包括同轴固定的第一正向棘轮64以及第一反向棘轮65。第一正向棘轮64上设置有第五正向棘齿641,第一反向棘轮65上设置有第五反向棘齿651,第一正向棘爪62转动安装于第一传动轮51的一侧面,第一正向棘爪62与第五正向棘齿641配合从而驱动第一正向棘轮64正向旋转。第一反向棘爪63转动安装于第一传动轮51的另一侧面上,第一反向棘爪63与第五反向棘齿651配合从而驱动第一反向棘轮65反向旋转。通过第一正向棘爪62与第五正向棘齿641以及第一反向棘爪63与第五反向棘齿651的配合作用,从而可以驱动车轮2的正向旋转或者反向旋转。第二棘轮71包括同轴固定的第二正向棘轮713以及第二反向棘轮714。第二正向棘轮713上设置有第六正向棘齿7131,第二反向棘轮714上设置有第六反向棘齿7141。第二正向棘爪72转动安装于第二传动轮52的一侧面,第二正向棘爪72与第六正向棘齿7131配合从而驱动第二正向棘轮713正向旋转。第二反向棘爪73转动安装于第二传动轮52的另一侧面,第二反向棘爪73与第六反向棘齿7141配合从而驱动第二反向棘轮714反向旋转。通过第二正向棘爪72与第六正向棘齿7131以及第二反向棘爪73与第六反向棘齿7141的配合作用,从而可以驱动车轮2的正向旋转或者反向旋转。
应当说明的是,如图41至图42所示,第一棘轮61与第二棘轮71之间的夹角α为第一棘轮61或者第二棘轮71上的相邻同向棘齿之间的夹角β的一半。其中,第一棘轮61与第二棘轮71之间的夹角α指的是以第一棘轮61或者第二棘轮71的转动中心为中心,第一棘轮61与第二棘轮71上相邻两个同向棘齿之间的夹角,即第一正向棘轮64上的第五正向棘齿641与第二正向棘轮713上的第六正向棘齿7131之间形成的夹角,如图41所示,或者,第一反向棘轮65上的第五反向棘齿651与第二反向棘轮714的第六反向棘齿7141之间形成的夹角。第一棘轮61与第二棘轮71之间的夹角α同时为工作角度,即该第一正向棘爪62、第一反向棘爪63、第二正向棘爪72或者第二反向棘爪73由行程最高点运动到行程最低点驱动第一棘轮61或者第二棘轮71转动的角度。第一棘轮61上的相邻同向棘齿之间的夹角β指的是第一正向棘轮64上的相邻的第五正向棘齿641之间形成的夹角,如图42所示,或者,第二正向棘轮713上的相邻的第六正向棘齿7131之间形成的夹角;或者,第一反向棘轮65上的的相邻的第五反向棘齿651之间形成的夹角,或者,第二反向棘轮714上的相邻的第六反向棘齿7141之间形成的夹角。由于在本实施中,第一棘轮61上的正反双向棘齿与第二棘轮71上的正反双向棘齿的数量均为一个,因此,夹角β为360°,此时夹角α为180°。
进一步地,请参阅图36以及图37,作为本申请第五实施例提供的脚踏平衡车的一种具体实施方式,换向机构8包括第三安装座861、第三转轴862、第三正向触动件863、第三反向触动件864、第四正向触动件865、第四反向触动件866以及第三摩擦件867。第三安装座861安装于车身1上,第三转轴862转动安装于第三安装座861上。第三正向触动件863、第三反向触动件864、第四正向触动件865、第四反向触动件866以及第三摩擦件867分别固定于第三转轴862上,从而使得第三正向触动件863、第三反向触动件864、第四正向触动件865、第四反向触动件866以及第三摩擦件867可以实现同步摆动。第三正向触动件863用于推动第一正向棘爪62翻转以使第一正向棘爪62与第一正向棘轮64分离。第三反向触动件864用于推动第一反向棘爪63翻转以使第一反向棘爪63与第一反向棘轮65分离。第四正向触动件865用于推动第二正向棘爪72翻转以使第二正向棘爪72与第二正向棘轮713分离。第四反向触动件866用于推动第二反向棘爪73翻转以使第二反向棘爪73与第二反向棘轮714分离。
其中,第三正向触动件863与第三反向触动件864的的安装方向相反,第四正向触动件865与第四反向触动件866的安装方向相反。当第三正向触动件863设置于第一正向棘爪62行程始点所在的位置时,第三反向触动件864设置于第一反向棘爪63行程终点所在的位置,第四正向触动件865设置于第二正向棘爪72行程始点所在的位置,第四反向触动件866设置于第二反向棘爪73行程终点所在的位置。当第三转轴862正向旋转(即朝着与车轮2前进方向相同的方向摆动)时,第三正向触动件863、第三反向触动件864、第四正向触动件865、第四反向触动件866正向摆动,此时第三正向触动件863与第一正向棘爪62错开(即第三正向触动件863离开触动位置),第三反向触动件864与第一反向棘爪63正对(即第三反向触动件864处于触动位置),第四正向触动件865与第二正向棘爪72错开(即第四正向触动件865离开触动位置),第四反向触动件866与第二反向棘爪73正对(即第四反向触动件866处于触动位置)。当第一正向棘爪62运动到第三正向触动件863所在的位置时,此时第三正向触动件863不会与第一正向棘爪62接触,从而使得第一正向棘爪62保持与第一棘轮61接触。当第一反向棘爪63运动到第三反向触动件864所在的位置时,此时第三反向触动件864与第一反向棘爪63接触,从而推动第一反向棘爪63翻转,从而使得第一反向棘爪63与第一棘轮61分离。当第二正向棘爪72运动到第四正向触动件865所在的位置时,此时第四正向触动件865不会与第二正向棘爪72接触,从而使得第二正向棘爪72保持与第二棘轮71接触。当第二反向棘爪73运动到第四反向触动件866所在的位置时,此时第四反向触动件866与第二反向棘爪73接触,从而推动第二反向棘爪73翻转,从而使得第二反向棘爪73与第二棘轮71分离。当第三转轴862反向旋转(即朝着与车轮2前进方向相反的方向摆动)时,第三正向触动件863、第三反向触动件864、第四正向触动件865、第四反向触动件866反向摆动,此时第三正向触动件863与第一正向棘爪62正对(即第三正向触动件863处于触动位置),第三反向触动件864与第一反向棘爪63错开(即第三反向触动件864离开触动位置),第四正向触动件865与第二正向棘爪72正对(即第四正向触动件865处于触动位置),第四反向触动件866与第二反向棘爪73错开(即第四反向触动件866离开触动位置)。当第一正向棘爪62运动到第三正向触动件863所在的位置时,此时第三正向触动件863与第一正向棘爪62接触,从而推动第一正向棘爪62翻转,从而使得第一正向棘爪62与第一棘轮61分离触。当第一反向棘爪63运动到第三反向触动件864所在的位置时,此时第三反向触动件864不会与第一反向棘爪63接触,从而使得第一反向棘爪63保持与第一棘轮61接触。当第二正向棘爪72运动到第四正向触动件865所在的位置时,此时第四正向触动件865与第二正向棘爪72接触,从而推动第二正向棘爪72翻转,从而使得第二正向棘爪72与第二棘轮71分离。当第二反向棘爪73运动到第四反向触动件866所在的位置时,此时第四反向触动件866不会与第二反向棘爪73接触,从而使得第二反向棘爪73保持与第二棘轮71接触。
第三摩擦件867用于与车轮2摩擦接触。优选的,该第三摩擦件867可通过扭簧等弹性固定在第三转轴862上,从而使得该第三摩擦件867与车轮2实现弹性摩擦接触。当车轮2正向旋转时,此时,第三摩擦件867由于受到车轮2摩擦力的作用,会带动第三转轴862正向摆动,第三正向触动件863、第三反向触动件864、第四正向触动件865、第四反向触动件866正向摆动,从而实现第一反向棘爪63与第二反向棘爪73的自动打开,避免第一反向棘爪63与第二反向棘爪73干涉车轮2的正向旋转。当车轮2反向旋转时,此时,第一摩擦片由于受到车轮2摩擦力的作用,会带动第三转轴862反向摆动,第三正向触动件863、第三反向触动件864、第四正向触动件865、第四反向触动件866反向摆动,从而实现第一正向棘爪62与第二正向棘爪72的自动打开,避免第一正向棘爪62与第二正向棘爪72干涉车轮2的反向旋转。

进一步地,请参阅图35以及图36,作为本申请第五实施例提供的脚踏平衡车的一种具体实施方式,换向机构8上设置有第二限位槽89,第三限位件882插入第二限位槽89中,从而可以在手动切换时限制第三正向触动件863、第三反向触动件864、第四正向触动件865、第四反向触动件866的摆动范围。

进一步地,请参阅图32,作为本申请第五实施例提供的脚踏平衡车的一种具体实施方式,脚踏平衡车还包括刹车装置30,该刹车装置30包括两分别安装于对应车轮2上的刹车片301、两个分别与各刹车片301一一对应并用于控制各刹车片301与对应的车轮2接触或者分离的刹车把302。通过刹车装置30的控制,可实现刹车以及换向操作。具体的,该刹车把302安装于车身1上,当需要刹车时,只需要摆动腿部触碰刹车把302即可实现对应车轮2的刹车操作,操作十分简单方便。
本申请第五实施例的脚踏平衡车的工作原理如下所示:
当第一脚踏3处于行程最高点,由于第一传动带53的带动,第二脚踏4位于行程的最高低点。首先,向下踏动第一脚踏3,通过第一传动带53带动第一传动轮51正向旋转,第二传动轮52反向旋转,此时,第一正向棘爪62通过与第五正向棘齿641的配合驱动第一棘轮61正向旋转,进而带动车轮2正向旋转。当车轮2正向旋转时,此时第三摩擦片由于受到车轮2摩擦力的作用,第三摩擦片带动第三转轴862正向旋转,从而使得第三正向触动件863、第三反向触动件864、第四正向触动件865、第四反向触动件866以及第三摩擦件867可以实现同步正向摆动,进而使得第三正向触动件863离开触动位置,第三反向触动件864处于触动位置,第四正向触动件865离开触动位置,第四反向触动件866处于触动位置。且由于第一传动带53的带动,当第一脚踏3向下运动时,该第二脚踏4向上运动。当第一脚踏3运动到行程最低点时,第二脚踏4位于行程的最高点,此时第一正向棘爪62随着第一传动轮51正向旋转至行程终点,第一反向棘爪63随着第一传动轮51正向旋转至行程终点,此时第二正向棘爪72随着第二传动轮52反向旋转到行程始点,第二反向棘爪73由于在行程终点时被第四反向触动件866推动与第二棘轮71分离,该第二反向棘爪73可越过第六反向棘齿7141随着第二传动轮52反向旋转至行程始点,避免第二反向棘爪73在没有打开的情况下导致与第六反向棘齿7141配合带动第二棘轮71反向旋转造成与第一棘轮61发生运动干涉的情况发生,从而使得当第一棘轮61处于工作状态时,第二棘轮71处于空旋状态,不会与第一棘轮61发生运动干涉。
接着,继续向下踏动第二脚踏4,通过第一传动带53带动第二传动轮52正向旋转,第一传动轮51反向旋转。此时,第二正向棘爪72通过与第六正向棘齿7131的配合驱动第二棘轮71正向旋转,进而带动车轮2正向旋转。当第二脚踏4运动到行程最低点时,第一脚踏3位于行程的最高点,此时第二正向棘爪72随着第二传动轮52正向旋转至行程终点,第二反向棘爪73随着第二传动轮52正向旋转到行程终点,第一正向棘爪62随着第一传动轮51反向旋转到行程始点,第一反向棘爪63由于在行程终点时被第三反向触动件864推动与第一棘轮61分离,该第一反向棘爪63可越过第五反向棘齿651随着第一传动轮51反向旋转至行程始点,避免第一反向棘爪63在没有打开的情况下导致与第五反向棘齿651配合带动第一棘轮61反向旋转造成与第二棘轮71发生运动干涉的情况发生,从而使得当第二棘轮71处于工作状态时,第一棘轮61处于空旋状态,不会与第二棘轮71发生运动干涉。进而完成车轮2前进的一个交替过程,通过反复踏动第一脚踏3与第二脚踏4,实现车轮2的持续前进。反之,车轮2的持续后退同理可实现。
本申请第五实施例的脚踏平衡车的换向操作原理如下所示:
当第一棘轮61处于工作状态时,此时第二棘轮71处于空旋状态,若向下踏动第一脚踏3时,通过第一传动带53带动第一传动轮51正向旋转,此时,第一正向棘爪62通过与第五正向棘齿641的配合驱动第一棘轮61正向旋转,进而带动车轮2正向旋转;若向下踏动第二脚踏4,通过第一传动带53带动第一传动轮51反向旋转,第一反向棘爪63通过与第五反向棘齿651的配合驱动第一棘轮61反向旋转,进而带动车轮2的反向旋转。可通过踏动不同的脚踏,实现车轮2旋转方向的改变,换向操作十分简单方便。
当第二棘轮71处于工作状态时,此时第一棘轮61处于空旋状态,若向下踏动第二脚踏4时,通过第一传动带53带动第二传动轮52正向旋转,此时,第二正向棘爪72通过与第六正向棘齿7131的配合驱动第二棘轮71正向旋转,进而带动车轮2正向旋转;若向下踏动第一脚踏3,通过第一传动带53带动第二传动轮52反向旋转,第二反向棘爪73通过与第六反向棘齿7141的配合驱动第二棘轮71反向旋转,进而带动车轮2的反向旋转。可通过踏动不同的脚踏,实现车轮2旋转方向的改变,换向操作十分简单方便。
以上所述仅为本申请的较佳实施例而已,并不用以限制本申请,凡在本申请的精神和原则之内所作的任何修改、等同替换和改进等,均应包含在本申请的保护范围之内。
