本发明的实施方式
为了使本发明的目的、技术方案及优点更加清楚明白,以下结合附图及实施例,对本发明进行进一步详细说明。应当理解,此处所描述的具体实施例仅仅用以解释本发明,并不用于限定本发明。
参见图 1- 图 8 ,为本发明所提供的双踏板控制万向脚轮。该万向脚轮适用安装于各种设备上,使得该设备能够自由转动、移动和刹车。具体地,该万向脚轮在医疗保健器械、零售业移动设备以及家用家具等设备上使用。接着,请详见图 1- 图 3 ,本发明实施例提供了一种双踏板控制万向脚轮结构,包括脚轮主架 1 、设于脚轮主架 1 两侧的一对脚轮组件 2 、设于脚轮主架 1 上的万向组件 5 以及设于脚轮主架 1 内的可踩踏刹车踏板 32 进行刹车的刹车模块 3 和可踩踏解刹踏板 41 恢复脚轮运动的解刹模块 4 。在主架 1 的两侧分别设有一组脚轮组件 2 ,使得该万向脚轮能够实现自由移动的基本功能。在脚轮主架 1 上设有的万向组件 5 ,使得脚轮安装于各种设备上时,能够实现全自由度的转向功能。同时,通过设于主架 1 内的刹车模块 3 能够通过踩踏刹车踏板 32 对脚轮进行刹车。该刹车模块 3 不仅能够控制两侧的脚轮组件 2 ,使得脚轮组件 2 停止转动,从而控制脚轮自由移动;同时还可以控制万向组件 5 ,使得脚轮无法发生转动,保证在刹车之后,脚轮完全处于'双锁'的状态,即停止自由移动,同时也停止转动。而对刹车模块 1 进行解刹时,不需要 将刹车踏板抬起进行解刹。可以直接通过本发明所提供的与刹车模块 3 同向的解刹模块 4 进行解刹。通过踩踏解刹模块 4 的解刹踏板 41 将刹车模块 3 中进行'双锁'的部件复位,从而进行解除刹车的状态,使得万向脚轮重新回到可全自由的移动和转动状态。而本发明中的刹车模块 3 与解刹模块 4 的刹车踏板 32 和解刹踏板 41 均采用同向受力的制动模式,使得刹车和解刹过程都容易操作,实现了双踏板的同向控制。
具体地,请参见图 4-1 至图 5 ,在脚轮主架 1 的两侧分别设有可供脚轮组件 2 放置的轮片槽 12 ,于轮片槽 12 内设有一中心轴 11 。脚轮组件 2 包括套设于中心轴 11 上的脚轮轮片 21 以及设于脚轮轮片 21 外侧的脚轮盖 22 。具体地,在脚轮轮片 21 中心设有一轴孔 211 。将轴承 23 装设与脚轮轮片 21 的轴孔 211 上,再将装有轴承 23 的脚轮轮片 21 固定于脚轮主架 1 的中心轴 11 上。于脚轮轮片 21 与脚轮盖 22 之间还设有一轴承盖 24 ,轴承盖 24 用于抵压轴承 23 的内圈,使得脚轮轮片 21 即固定于脚轮主架 1 的中心轴 11 上,又可沿中心轴 11 转动。而轴承盖 24 通过脚轮盖 24 紧压于脚轮轮片 21 上。脚轮盖 22 卡扣于脚轮轮片 21 的外侧。脚轮盖 22 一侧沿其圆周方向均设有四个垂直于脚轮盖 22 的卡钩 221 ,与其对应的在脚轮轮片 22 上沿其圆周方向也均设有四个与卡钩 221 配合的卡槽 213 。脚轮盖 22 通过卡钩 221 卡扣于脚轮轮片 21 的卡槽 213 内,且将轴承盖 24 紧压与轴承 23 的内圈上。
然后,请参见图 4-1 ,在脚轮主架 1 上设有一主轴孔 15 ,万向组件 5 包括一主轴盖 51 、轴承 53 以及万向制动齿轮组 52 ,万向制动齿轮组 52 包括相互啮合的上齿轮 521 和下齿轮 522 ,万向制动齿轮组 52 套设于一轴承 53 内,万向制动齿轮组 52 以及轴承 53 通过主轴盖 51 固定于主轴孔 15 内。具体地,适用该万向脚轮的设备通过一轴体与万向组件 5 固定连接。并且该万向脚轮也是通过该万向组件 5 控制脚轮整体的自由转动,因其包括万向制动齿轮组 52 。其上齿轮 521 设有可供轴体通过的通孔,上齿轮 521 包括一上筒体以及与上筒体上端连接的上挡圈,该通孔贯穿于上筒体以及上挡圈,且于上筒体的下端设有与下齿轮 522 配合的第一啮合齿。该上齿轮 521 的上筒体套设于轴承 53 内,且上挡圈抵压于轴承 53 的内圈上。其下齿轮 522 也设有可供轴体通过的通孔,下齿轮 522 包括一下筒体以及与下筒体下端连接的下挡圈,该通孔贯穿于下筒体以及下挡圈,且于下筒体的上端设有与上齿轮 521 的第一啮合齿配合的第二啮合齿。该下齿轮 522 的下筒体套设于轴承 53 内,且下挡圈抵压于轴承 53 的外圈上。该下齿轮 522 的下挡圈设于脚轮主架 1 的主轴孔 15 底部,上齿轮 521 通过主轴盖 51 锁紧于主轴孔 15 上,且将上齿轮 521 抵压于轴承 53 上。在万向脚轮处于自由转动的状态时,上齿轮 521 的上筒体和下齿轮 522 的下筒体虽然都套设于轴承 53 内,但是上筒体与下筒体两者之间存在一端距离,因此两者之间的第一啮合齿与第二啮合齿无法接触。
然后,请参见图 3 及图 6 ,在脚轮主架 1 内部设有刹车槽 13 ,刹车模块 3 置于刹车槽 13 内,刹车模块 3 包括设于刹车槽 13 内的刹车块 31 以及套设于刹车块 31 内且一端延伸至脚轮主架 1 外侧可将刹车块 31 向上顶起的刹车踏板 32 。具体地,在脚轮主架 1 的内部设有一个中空槽 131 ,该中空槽 131 与主轴孔 15 之间设有一通孔(图中未示出)连接。万向组件 5 的下齿轮 522 的底部设有第一万向啮合齿 5221 ,刹车块 31 顶部设有一顶片 315 ,于所述顶片 315 上设有与第一万向啮合齿 5221 的第二万向啮合齿 3151 。该刹车块 31 的顶片 315 通过中空槽 131 与主轴孔 15 之间的通孔(图中未示出)可与主轴孔 15 内的万向组件 5 触碰。当踩踏刹车踏板 32 时,刹车踏板 32 将刹车块 31 向上顶起,刹车块 31 的顶片 315 向上运动,与万向组件 5 的下齿轮 522 接触,此时第一万向啮合齿 5221 与第二万向啮合齿 3151 啮合,导致下齿轮 522 无法转动,同时,由于刹车块 31 向上运动,推动下齿轮 522 向上运动,导致万向制动齿轮组 52 的上齿轮 521 与下齿轮 522 接触,因此万向制动齿轮组 52 的第一啮合齿与第二啮合齿相互啮合,使得上齿轮 521 也无转动,同时万向制动齿轮组 52 从上下紧压轴承 53 ,使得轴承 53 的内外圈均无法转动,从而控制万向脚轮相对于连接设备的轴体无法转动。即,当刹车块 31 向上顶起时,通过顶片 315 锁紧万向制动齿轮组,从而控制整个万向脚轮相对于连接的设备无法转动,从而将万向脚轮的转动方向锁死。
具体地,参见图 5 ,在脚轮轮片 21 的一侧设有一环形槽 212 ,于环形槽 212 的内环壁表面设有第一刹车啮合齿 2121 。而刹车块 31 包括一主体 31 、设于主体 31 中心可沿与脚轮主架 1 的中心轴 11 上下移动的定位孔 311 以及由主体 31 底部两侧向外延伸的刹车片 312 ,刹车片 312 穿过车轮主架 1 插设于脚轮轮片 21 的环形槽 212 内,于刹车片 312 上表面设有与第一刹车啮合齿 2121 配合的第二刹车啮合齿 3121 。在脚轮主架 1 的底部还设有一个侧槽 132 ,该侧槽 132 将中空槽 131 与轮片槽 12 连接。而该刹车片 312 正好设置于脚轮主架 1 的侧槽 132 内。在万向脚轮的脚轮轮片 21 正常转动时,该刹车片 312 仅是穿过该侧槽 132 插设于脚轮轮片 21 的环形槽 212 内,此时的第一刹车啮合齿 2121 与第二刹车啮合齿 3121 相互不接触,因此刹车块 31 对脚轮轮片 21 的转动不产生影响。当踩踏刹车踏板 32 时,刹车踏板 32 将刹车块 31 向上顶起,刹车块 31 上的刹车片 312 随着向上运动,此时的第一刹车啮合齿 2121 与第二刹车啮合齿 3121 之间相互啮合,通过刹车片 312 控制脚轮轮片 21 ,使其无法转动,从而对万向脚轮进行刹车,使得万向脚轮无法移动,将万向脚轮的脚轮轮片 21 锁死。
因此,当踩踏刹车踏板 32 时,刹车踏板 32 将刹车块 31 向上顶起,使得刹车块 31 顶部的顶片 315 与万向组件 5 连接,从而控制万向脚轮的转动方向;同时使得刹车块 31 两侧的刹车片 312 向上运动与位于脚轮主架 1 两侧的脚轮轮片 21 连接,从而控制万向脚轮的脚轮轮片转动,完成万向脚轮的转动方向锁死以及刹车的作用。
具体地,在刹车块主体 31 内侧设有一中空槽 314 ,刹车踏板 32 包括一主体 321 以及与主体 321 连接且向外延伸的一踏板 322 ,主体 321 上设有一所述脚轮主架 1 的中心轴 11 同心的中心孔 3211 ,且于所述主体 321 外侧设有一可与刹车块 31 接触的圆弧面 3212 ,主体 321 套设于刹车块主体 31 的中空槽 314 内。在本发明中,当踩踏刹车踏板 32 时,刹车踏板的主体 321 沿中心孔 3211 转动,而圆弧面 3212 与刹车块 31 内部抵接。当踩踏刹车踏板 322 的踏板 322 向下运动时,圆弧面 3212 抵接刹车块 31 向上运动,从而完成万向脚轮的刹车与停止脚轮转动的过程。在刹车块主体 31 上设有一定位柱 313 ,脚轮主架 1 内部设有与定位柱 313 配合的定位孔(图中未示出),于定位柱 313 上还设有一限位弹簧 33 。由于踩踏刹车踏板 32 时,刹车踏板 32 是沿该圆弧面 3212 转动从而将刹车块 31 顶起,因此当刹车块 31 的顶片 315 抵接到万向组件 5 的下齿轮 522 时,达到刹车块 31 的最高点,此时定位柱 313 上的限位弹簧 33 达到极限状态,使得刹车块 31 无法再向上运动,而刹车踏板 32 也将无法再向下踩踏。该限位弹簧 33 起到限制刹车块 31 向上运动的作用。
而在刹车块 31 的主体上设有一斜面 316 ,解刹踏板 41 的顶杆 412 抵接于斜面 316 上。当向下踩踏解刹踏板 41 时,解刹踏板 41 的顶杆 412 沿限位轨道 141 向下运动,从而顶杆 412 抵触刹车块 31 的斜面 316 ,使得刹车块 31 受到向下运动的力,刹车块 31 向下运动,使得刹车块 31 上的顶片 315 与万向组件 5 的下齿轮 522 分离,从而使得万向脚轮重新获得万向转动,并且刹车块 31 的刹车片 312 的第二刹车啮合齿 3121 与脚轮轮片 21 的第一刹车啮合齿 2121 分离,使得脚轮轮片 21 重新获得转动。使得该万向脚轮从'双锁'状态中解除。并且刹车块 31 向下运动时,带动刹车踏板 32 沿着中心孔 3211 转动,刹车踏板 32 的踏板 322 向上复位到初始状态。
具体地,该斜面 316 与垂直的水平面呈锐角,角度在 20~40 °之间。若该斜面 316 设置不合理,则踩踏该解刹踏板 41 也无法将刹车块 31 推下,就无法完成解除刹车的动作。
具体地,请参见图 3 至图 4-2 以及图 8 ,在脚轮主架 1 上设有一解刹槽 14 以及沿解刹槽 14 轴向设置的限位轨道 141 ,解刹模块 4 设于解刹槽 14 内,解刹模块 4 包括解刹踏板 41 以及限位轴 43 ,解刹踏板 41 包括一踏板 411 以及垂直于踏板 411 上的顶杆 412 ,于顶杆 412 上设有一可供限位轴 43 穿过的限位孔 413 ,限位轴 43 穿设于顶杆 412 的限位孔 413 内可沿脚轮主架 1 上的限位轨道 141 来回移动,顶杆 412 抵接于刹车模块 3 上,解刹模块 41 还包括一复位弹簧 42 ,复位弹簧 42 设于顶杆 412 上。该解刹槽 14 设于脚轮主架 1 的上方。踏板 411 设于解刹槽 14 外侧可供踩踏控制,而与踏板 411 连接的顶杆 412 插入所述解刹槽 14 内。在解刹槽 14 的轴向上还设有一个限位轨道 141 ,该限位轨道 141 为分别设置在脚轮主架 1 的左右轮片槽 12 上的一个可贯通左右轮片槽 12 的长形腰孔,且该长形腰孔沿解刹槽 14 的轴向设置。限位轴 43 架设于该长形腰孔上,且可沿该长形腰孔的设置方向来回移动。而在顶杆 412 上设置的限位孔 413 两端可分别与设于脚轮主架 1 上的长形腰孔连接,使得限位轴 43 可同时穿过限位轨道 141 以及限位孔 413 来回移动,即限位轴 43 可沿着解刹槽 14 的轴向方向来回移动。因此顶杆 412 受到限位轴 413 以及限位轨道 141 的相互作用控制下仅能沿着解刹槽 14 的轴向方向来回移动。当踩踏刹车踏板 41 时,刹车踏板 41 可沿解刹槽 14 的轴向方向运动。而在顶杆 412 上还加设了复位弹簧 42 ,该复位弹簧 42 的一端抵接于踏板 411 与顶杆 412 的连接处,另一端抵接于解刹槽 14 的底部。在踩踏解刹踏板 41 时,踏板 411 受到向下的作用力,使得顶杆 412 抵接于刹车模块 3 上,且推动刹车模块 3 向下移动,从而解除刹车模块 3 的刹车动作。放开踏板 411 后,由于受到复位弹簧 42 的作用,踏板 411 自动向上回位,顶杆 412 离开刹车模块 3 。而解刹踏板 41 的运动完全是沿解刹槽 14 的轴向来回移动,仅对刹车模块 3 进行控制,不会对脚轮的其他部件造成影响。
综上所述,本发明所提供的双踏板控制万向脚轮设有万向组件,使得脚轮可以万向自由转动;还设有刹车模块 3 ,该刹车模块 3 通过刹车踏板 3 不仅可以控制将脚轮上的脚轮轮片 21 锁死使其无法转动,还可以将万向控制方向锁死,使得整个脚轮不能随意转动;同时还设有解刹模块 4 ,该解刹模块 4 通过与刹车模块 3 同向的解刹踏板 41 将双锁状态解除,具体地,踩踏解刹踏板 41 ,将刹车模块 3 的刹车块 31 推下从而使脚轮重新获得自由度,该解刹模块 4 使得解刹不需要再将刹车踏板抬起那么麻烦,刹车和解刹两个动作都方便易行,容易操作。
以上仅为本发明的较佳实施例而已,并不用以限制本发明,凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等,均应包含在本发明的保护范围之内。
