发明实施例
本发明的实施方式
[0040] 为了便于理解本实用新型, 下面将参照相关附图对单脚式车体进行更全面的描 述。 附图中给出了单脚式车体的首选实施例。 但是, 单脚式车体可以以许多不 同的形式来实现, 并不限于本文所描述的实施例。 相反地, 提供这些实施例的 目的是使对单脚式车体的公开内容更加透彻全面。
[0041] 除非另有定义, 本文所使用的所有的技术和科学术语与属于本实用新型的技术 领域的技术人员通常理解的含义相同。 本文中在单脚式车体的说明书中所使用 的术语只是为了描述具体的实施例的目的, 不是旨在于限制本实用新型。 本文 所使用的术语“及 /或”包括一个或多个相关的所列项目的任意的和所有的组合。
[0042] 如图 1所示, 一实施方式的单脚式车体 10对应于用户的单脚, 两个单脚式车体 1 0则构成一套代步工具, 分别对应于用户的左脚和右脚。 两个单脚式车体 10之间 相互独立, 两个单脚式车体 10之间不仅能够相对扭转, 两者间的左右间距和前 后间距也能改变, 从而用户能够分别调整左脚和右脚的状态, 以适应不同的路 况。
[0043] 例如, 在骑乘过程中, 用户能够增大两个单脚式车体 10之间的距离, 以避开路 面上的坑穴; 用户还能够采用一脚在前一脚在后的骑乘姿势, 以经过宽度较窄 的路段; 在不平整的路面行驶时, 用户还可以分别调整两个单脚式车体 10的相 对位置, 以避免路面不平而引起的重心高度急剧变化。 因此, 本实施方式的单 脚式车体 10的灵活性和安全性都更高。
[0044] 与传统的双轮平衡车、 扭扭车相比, 本实施方式的代步工具能够省略掉时刻保 证两个车体同轴设置的连接结构, 从而能够大大减小代步工具的体积, 提高代 步工具的便携性。
[0045] 值得一提的是, 为了进一步提高代步工具的安全性, 可以使得两个单脚式车体 10通信连接, 控制两个单脚式车体 10的前后间距和左右间距均在预设安全值内 , 以减少安全隐患。 在骑乘过程中, 当两个单脚式车体 10之间的前后间距超过 预设前后安全值时, 控制两个单脚式车体 10同时安全停车, 以避免出现其中一 个单脚式车体 10停止运行而另一个单脚式车体 10继续运行的危险情况。 同样地 , 当两个单脚式车体 10之间的左右间距超过预设左右安全值时, 控制两个单脚 式车体 10同时安全停车。 而在预设安全值范围内, 两个单脚式车体 10能够照常 独立运行, 因此, 两个单脚式车体 10通信连接并不妨碍两个单脚式车体 10独立 运行。
[0046] 另外, 若其中一个单脚式车体 10损坏, 可以仅更换一个单脚式车体 10, 达到节 约维修成本的目的。
[0047] 在本实施方式中, 两个单脚式车体 10的结构基本相同, 下面就以其中一个单脚 式车体 10为例, 具体介绍单脚式车体 10的结构。
[0048] 请参考图 1及图 2, 单脚式车体 10包括车架 100、 轮毂电机 200、 固定组件 300及 控制组件 400, 轮毂电机 200及控制组件 400均与车架 100连接, 固定组件 300与车 架 100连接, 以固定轮毂电机 200, 控制组件 400与轮毂电机 200电气连接, 以维 持车架 100的平衡状态, 实现平稳地骑乘。
[0049] 其中, 车架 100上设有承载面 110, 承载面 110用于供用户的单脚踩踏, 且承载 面 110能与用户的脚部接触的面积用于匹配用户的单脚大小, 也就是说, 不管承 载面 110是一个连续的平面还是由几个分隔开的平面共面形成的, 承载面 110上 能够供用户站立的面积与用户的单脚大小相匹配。 正常来说, 普通人的脚长大 概在 20-30cm范围内, 脚宽大概在 6.5-10.5cm范围内, 承载面 110的大小可以设计 为均码, 长度大约为 15-30cm, 宽度大约为 8-20cm, 以适用于不同的用户。 对于 不同的单脚式车体 10, 承载面 110的大小也可以参照鞋码来分别设计, 以使用户 能够选择适合自己的单脚式车体 10, 带给用户更为舒适的骑乘体验。
[0050] 承载面 110平行于地面时, 轮毂电机 200位于承载面 110与地面之间, 这里所说 的平行包括了略微倾斜以及略微弯曲的情况。 更为具体地, 单脚式车体 10前后 对称, 轮毂电机 200的轴线以及轮毂电机 200与地面的交线确定的平面即为单脚 式车体 10的对称面。 在骑乘的过程中, 轮毂电机 200大致位于用户脚掌的中心区 域的正下方, 从而能够降低用户掌握平衡的难度。
[0051] 从图 1和图 2中可以看出, 用户在单脚式车体 10上的踩踏区域为开放式的, 与对 脚部的包裹式设计相比, 本实施方式的单脚式车体 10大大简化了骑行前的穿戴 手续和骑行后的脱卸手续, 极其方便。 在用户失去平衡而无法控制单脚式车体 1 0的紧急情况下, 用户可以直接脱离承载面 110, 跳下单脚式车体 10, 避免摔伤
[0052] 一实施例中, 如图 7所示, 在开放式的基础上, 为了提高单脚式车体 10的可控 性, 车架 100包括壳体 120及防滑垫 130, 壳体 120起主要承重作用, 防滑垫 130通 过胶粘、 卡扣或螺纹连接的方式设置在壳体 120远离轮毂电机 200的一面, 承载 面 110即为防滑垫 130远离轮毂电机 200的一面。 防滑垫 130由砂纸、 橡胶或硅胶 等材质制成, 能够增大承载面 110与用户脚部之间的摩擦力, 从而用户能带动单 脚式车体 10做出以腿部为轴的转向动作, 或是前倾、 后仰等倾斜动作。
[0053] 此外, 如图 12所示, 单脚式车体 10还包括限位件 140, 限位件 140设于车架 100 上, 并凸出于承载面 110, 限位件 140设有两个, 分别位于车架 100的两侧, 且其 中一个限位件 140至另一个限位件 140的方向与轮毂电机 200的轴向平行。 两个限 位件 140起到辅助固定用户脚部的作用, 当用户骑乘单脚式车体时, 两个限位件 140能略微卡住用户的脚部, 以便用户在完成跳跃或抬脚等动作时, 能带动单脚 式车体 10—起运动, 而防止脚部与单脚式车体 10分离。 限位件 140对脚部的挤压 力并不大, 从而不会妨碍用户在紧急情况下跳下单脚式车体 10, 用户只需稍作 用力甩掉单脚式车体 10即可。 因此, 这与上面所说的开放式踩踏区域并不矛盾
[0054] 参照图 1及图 2, 在本实施方式中, 轮毂电机 200包括轮胎 210、 轮毂 220及中心 轴 230, 其中, 轮胎 210用于接触地面, 轮毂 220与轮胎 210配合设置, 中心轴 230 穿设于轮毂 220。
[0055] 对于轮毂电机 200来说, 轮胎 210可以设置一个, 也可以设置两个或多个, 这里 所说的多个大于等于三个。 当轮胎 210的数目大于一个时, 这些轮胎 210共用一 个轮毂 220, 换句话说, 就是这些轮胎 210间隔排列在一个轮毂 220上, 也就意味 着, 单脚式车体 10在完成前倾、 后仰、 侧倾等倾斜动作时, 均是通过这一个轮 毂 220实现的, 用户对单脚式车体 10施加的压力也落在这一个轮毂 220上, 更加 方便用户转向。
[0056] 而当轮胎 210的数目为一个时, 轮毂电机 200与地面之间为线接触。 而且, 承载 面 110平行于地面时, 承载面 110与地面之间的距离较小, 也即, 对于本实施方 式的单脚式车体 10来说, 轮毂电机 200与地面接触的轴向长度较大, 而单脚式车 体 10的整体高度较低, 从而能够加强骑乘过程中的稳定性, 有助于用户保持平 衡。 因此, 这种结构的单脚式车体 10更为适合初学者。
[0057] 具体地, 在轮毂电机 200触地且承载面 110平行于地面时, 轮毂电机 200与地面 之间的多个共线的交点中, 相距最远的两个交点之间的连线的长度为 50-200mm , 且该连线的长度与承载面 110距离地面的高度的比值为 0.6-3。
[0058] 进一步, 相距最远的两个交点之间的连线的长度为 60-100mm, 且该连线的长 度与承载面 110距离地面的高度的比值为 0.8-1.5。
[0059] 轮毂电机 200与地面接触的轴向长度较大, 能够有效防止转弯时单脚式车体 10 侧翻, 避免用户崴脚和摔倒。 再加上承载面 110与地面之间的距离较小, 从而能 降低用户在骑行过程中的重心, 便于用户掌握平衡, 提高单脚式车体的稳定性 和安全性。
[0060] 在其他实施方式中, 轮胎 210还可以为其他形状, 比如, 如图 11所示, 轮胎 210 包括主体部 212及触地部 214, 主体部 212与触地部 214同轴设置, 且主体部 212的 直径小于触地部 214的直径。 触地部 214设有两个, 分别设于主体部 212的两端。 轮胎 210触地时, 只有触地部 214会接触地面, 而主体部 212与地面间隔。 这样, 在不改变轮胎 210与地面之间相距最远的两个交点之间的距离与承载面 110距离 地面的高度的比值的前提下, 能够减小轮胎 210与地面的接触面积, 从而能有效 减缓因路面不平整造成的颠簸, 还能避免轮胎 210与车架 100干涉, 并预留出一 定的走线空间。
[0061] 另外, 如图 4所示, 车架 100远离承载面 110的一侧设有容置槽 102, 轮毂电机 20 0的部分结构位于容置槽 102内, 以使单脚式车体 10整体的高度得以减小, 降低 单脚式车体 10自身的重心, 提高稳定性。 而且, 承载面 110与轮毂电机 200之间 的最小距离 H小于 2cm, 且该最小距离与轮毂电机 200的直径 D的比值小于 1:4。 进 一步, 承载面 110与轮毂电机 200之间的最小距离 H小于 lcm, 且该最小距离与轮 毂电机 200的直径 D的比值小于 1 :4。
[0062] 值得一提的是, 平衡状态下, 轮毂电机 200在地面上的投影完全落入承载面 110 在地面上的投影所形成的区域内, 以进一步增强单脚式车体 10结构的稳定性。
[0063] 此外, 设定一个垂直于轮毂电机 200的轴线的参照面, 该参照面为一个虚拟投 影面。 工作状态下, 单脚式车体 10与地面之间的多个交点在参照面上的正投影 重合为一点, 也即, 单脚式车体 10与地面之间的多个交点共线, 而且, 单脚式 车体 10与地面接触的滚动体有且仅有一个轮毂电机 200。
[0064] 图 5所示为单脚式车体 10的停车状态, 在该状态下, 中心轴 230的轴线平行于地 面, 且车架 100的一侧与地面接触, 中心轴 230的轴线在地面上的投影为 B, 车架 100的最高点在地面上的投影为 A, 车架 100与地面的接触点为 C, B位于 A与(:之 间。 因此, 车架 100与中心轴 230形成了类似跷跷板的结构, 用户的脚部踩在承 载面 110上时, 能够顺利地将车架 100踩至水平状态。 [0065] 如图 2、 图 3及图 5所示, 车架 100上还开设有收线槽 104, 收线槽 104沿轮毂电机 200的径向延伸。 轮毂电机 200还包括电机线 240, 轮毂电机 200的中心轴 230沿其 轴向开设有接线通道 232, 接线通道 232具有出口 234, 电机线 240穿设于接线通 道 232内, 且电机线 240的一端穿过出口 234从中心轴 230的侧周面伸出, 并收容 于收线槽 104内, 也即, 电机线 240呈弯折状。 车架 100能起到保护电机线 240的 作用, 这样, 就无需额外设置遮挡和保护电机线 240的挡板, 也就不会有挡板等 零部件占用轮毂电机 200轴向上的空间, 不仅大大减小了轮毂电机 200在轴向上 的尺寸, 进而减小了单脚式车体 10的体积, 也简化了轮毂电机 200的结构, 降低 了单脚式车体 10的生产成本。 可以理解, 在其他实施方式中, 收线槽 104也可以 省略。
[0066] 中心轴 230的端面呈 D字型。 具体地, 中心轴 230上还开设有安装槽 236, 安装槽 236的底壁 2362沿中心轴 230的轴向延伸, 且在固定组件 300的作用下, 安装槽 23 6的底壁 2362与车架 100抵接, 安装槽 236的底壁 2362用于承载负载和传递扭矩。 安装槽 236的侧壁 2364位于中心轴 230的两端之间, 安装槽 236的底壁 2362连接安 装槽 236的侧壁 2364与中心轴 230的其中一个端面, 出口 234位于安装槽 236的侧 壁 2364上。
[0067] 在本实施方式中, 安装槽 236的底壁 2362沿中心轴 230的径向方向上宽度等于中 心轴 230的直径, 也即中心轴 230的轴线位于安装槽 236的底壁 2362上。 此时, 底 壁 2362的宽度最大, 可以增大中心轴 230的承受尺寸, 减小中心轴 230受到的应 力。 在其他实施方式中, 底壁 2362也可以平行于中心轴 230的轴线, 此时, 底壁 2362沿中心轴 230的径向方向上宽度小于中心轴 230的直径。
[0068] 固定组件 300主要通过固定中心轴 230的方式固定轮毂电机 200。 具体地, 固定 组件 300包括固定件 310及连接件 320, 固定件 310通过连接件 320与车架 100连接 , 中心轴 230夹持于固定件 310与车架 100之间。 在本实施方式中, 固定组件 300 设有两组, 两组固定组件 300分别将中心轴 230的两端固定在车架 100上。 在其他 实施方式中, 轮毂电机 200也可以仅通过固定中心轴 230的一端而固定在车架 100 上, 也即固定组件 300仅设置一组即可。
[0069] 如图 2及图 6所示, 控制组件 400能够通过控制轮毂电机 200的转动来维持车架 10 0的平衡状态。 具体地, 控制组件 400包括姿态传感器 410、 控制器 420及电源 430 , 姿态传感器 410能够检测车架 100的倾斜角度, 并将车架 100的倾斜角度发送至 控制器 420, 控制器 420与轮毂电机 200连接, 控制器 420能够根据车架 100的倾斜 角度, 控制轮毂电机 200的转速。 电源 430能够向姿态传感器 410及控制器 420供 电。
[0070] 例如, 用户带动车架 100前倾时, 姿态传感器 410能将车架 100前倾的角度发送 给控制器 420, 控制器 420便能根据前倾的角度, 控制轮毂电机 200正向旋转, 而 使得单脚式车体完成前进的动作。 用户还能通过调整前倾的角度来改变单脚式 车体 10前进的速度, 通常来说, 前倾的角度越大, 轮毂电机 200的转速越大, 单 脚式车体 10前进的速度就越快。
[0071] 用户带动车架 100后仰时, 姿态传感器 410能将车架 100后仰的角度发送给控制 器 420, 控制器 420便能根据后仰的角度, 控制轮毂电机 200反向旋转, 而使得单 脚式车体 10完成后退的动作。 用户还能通过调整后仰的角度来改变单脚式车体 1 0后退的速度, 通常来说, 后仰的角度越大, 轮毂电机 200的转速越大, 单脚式 车体 10后退的速度就越快。
[0072] 用户可以通过控制两个单脚式车体 10的差速运行, 来完成转弯的动作。 比如, 用户重心向左倾斜, 同时, 左脚对应的单脚式车体 10的前进速度小于右脚对应 的单脚式车体 10的前进速度, 便能实现左转弯。 用户重心向右倾斜, 同时, 左 脚对应的单脚式车体 10的前进速度大于右脚对应的单脚式车体 10的前进速度, 便能实现右转弯。 当然, 对于本实施方式的代步工具来说, 还能实现后退式转 弯, 提高了娱乐性。
[0073] 在本实施方式中, 姿态传感器 410为陀螺仪, 与控制器 420集成在同一电路板 44 0上, 以起到简化结构, 压缩体积的效果。
[0074] 在图 2所示的实施例中, 车架 100内设有空腔 106 , 控制组件 400容置于空腔 106 内, 从而能避免灰尘、 水等外界因素影响控制组件 400的正常工作。
[0075] 具体地, 车架 100内设有第一腔室 1062与第二腔室 1064, 第一腔室 1062与第二 腔室 1064相互连通形成空腔 106。
[0076] 电源 430包括多个相互之间电连接的电芯, 多个电芯被分成第一组电芯 430a及 第二组电芯 430b。 第一组电芯 430a中的电芯的数目小于第二组电芯 430b中电芯的 数目, 且第一组电芯 430a容置于第一腔室 1062内, 第二组电芯 430b容置于第二腔 室 1064内, 集成有姿态传感器 410与控制器 420的电路板 440容置于第一腔室 1062 内。
[0077] 对于图 2所示的实施例, 这样布局电源 430, 能够进一步减小承载面 110与地面 之间的距离, 从而能进一步降低用户的重心, 进而能进一步提高单脚式车体 10 的稳定性和安全性。
[0078] 在其他实施方式中, 电源 430也可以设置在车架 100的外侧, 比如图 12所示的实 施例中, 两组电芯 432分别设置在轮毂电机 200的前后两侧或左右两侧, 其中, 每组中电芯 432的数目可以相同, 也可以不同, 数目不同时, 可以在数目较少的 一组中添加配重块来平衡轮毂电机 200的轴线的两侧的重量。 或者, 如图 8所示 , 电源 430还可以设置在承载面 110与轮毂电机 200之间。 再或者, 电源 430还可 以为一整体结构, 布置在轮毂电机 200的侧面, 比如图 9和图 10所示的那样。 当 然, 电源 430的数目还可以是多个, 多个电源 430均布置在轮毂电机 200的一侧, 或分散在轮毂电机 200的不同侧。
[0079] 在本实施方式中, 如图 2及图 4所示, 控制组件 400还包括脚踏感应器 450, 脚踏 感应器 450为机械行程开关、 薄膜感应开关或霍尔元件等。
[0080] 脚踏感应器 450安装在车架 100上, 并位于承载面 110所在的区域内。 脚踏感应 器 450用于检测用户是否踩踏在承载面 110上, 且当用户脱离承载面 110时, 脚踏 感应器 450能制动轮毂电机 200, 以避免单脚式车体 10失控, 撞上他人或其它物 件而损坏。
[0081] 具体地, 脚踏感应器 450包括第一感应器 452及第二感应器 454, 第一感应器 452 对应设置在脚尖的踩踏位置上, 第二感应器 454对应设置在脚跟的踩踏位置上。 可以理解, 在其他实施方式中, 第一感应器 452还可以与第二感应器 454—体成 型, 也即图 7中所示的呈一整体的脚踏感应器 450。
[0082] 请参考图 2, 单脚式车体 10还包括装饰灯 500, 装饰灯 500设有两个, 分别位于 轮毂电机 200的两端, 以遮挡和保护电机线 240及固定组件 300。 装饰灯 500呈圆 盘状, 除了起到装饰作用外, 还可以起警示作用, 用于显示电量等。 [0083] 此外, 同时结合图 2及图 4, 车架 100还包括第一防撞片 610及第二防撞片 620, 第一防撞片 610设置在车架 100的前侧, 车架 100的前侧与地面接触时, 第一防撞 片 610与地面抵接。 第二防撞片 620设置在车架 100的后侧, 车架 100的后侧与地 面接触时, 第二防撞片 620与地面抵接。 第一防撞片 610与第二防撞片 620用于停 车或与外物撞击时承受磨损, 一般由橡胶、 尼龙等耐磨材质制成。
[0084] 进一步, 车架 100还包括防撞条 630, 防撞条 630设有多个, 分别设置在车架 100 的四周。 防撞条 630由橡胶等具有一定弹性的材料制成, 能够缓冲与外物撞击时 的冲击力, 并保护车架 100。 在本实施方式中, 多个防撞条 630—体成型, 相互 之间首尾连接。 在其他实施方式中, 多个防撞条 630之间也可以间隔设置。
[0085] 以上所述实施例的各技术特征可以进行任意的组合, 为使描述简洁, 未对上述 实施例中的各个技术特征所有可能的组合都进行描述, 然而, 只要这些技术特 征的组合不存在矛盾, 都应当认为是本说明书记载的范围。
[0086] 以上所述实施例仅表达了本实用新型的几种实施方式, 其描述较为具体和详细 , 但并不能因此而理解为对实用新型专利范围的限制。 应当指出的是, 对于本 领域的普通技术人员来说, 在不脱离本实用新型构思的前提下, 还可以做出若 干变形和改进, 这些都属于本实用新型的保护范围。 因此, 本实用新型专利的 保护范围应以所附权利要求为准。
