Description

电动平衡车 技术领域
本申请涉及机电领域，尤其涉及一种电动平衡车。
背景技术
电动平衡车，又称体感车、思维车、摄位车等，目前市场上主要有独轮和双轮两类，其运作原理主要是建立在一种被称为“动态稳定(Dynamic Stabilization，DS)”的基本原理上，利用车体内部的陀螺仪和加速度传感器，来检测车体姿态的变化，并利用伺服控制系统，精确地驱动电机进行相应的调整，以保持系统的平衡。
通常，双轮的电动平衡车主要包括两个带有轮轴的轮毂电机、位于两个轮毂电机之间的踏板系统等一系列部件，踏板系统包括两个踏板组件，踏板组件包括承重基体及脚踏件，承重基体直接套设于轮毂电机的轮轴上并与之相固定。由于承重基体直接与轮毂电机的轮轴相固定，使得用户在踏上踏板组件后起所产生的承重力直接刚性传递到轮毂电机的轮轴，造成用户的不舒适感，也容易对轮毂电机的轮轴产生刚性的冲击力，容易损坏轮轴；另外，由于轮毂电机的轮轴处于其轴向的中心位置，使得电动平衡车在地面移动时，承重基体离地面的距离较小，承重基体及附着于承重基体的位于靠地面一侧面上的部件(如锂电池组件)等容易碰触到地面上较陡的地方，易对承重基体及上述部件产生损伤，甚至会产生安全问题。

下面通过具体实施方式结合附图对本申请作进一步详细说明。
实施例一：
本实施例提供了一种电动平衡车，其主要是一种双轮电动自平衡扭扭车。
如图1-3所示，该电动平衡车主要包括：带有轮轴11的车轮组件1以及踏板系统2。车轮组件1为轮毂电机。踏板系统2包括：两个踏板组件21，每个踏板组件21对应与一个车轮组件1相装配。踏板组件21包括：承重基体211以及悬挂架212。其中，如图4-5所示，悬挂架212包括：与轮轴11相抵接并固定的支撑部2121、与承重基体211相装配且分设于轮轴11的轴向在承重基体211上的投影线两侧的受力部2122，以及，位于支撑部2121与受力部2122之间的连接部2123。受力部2122上接受由承重基体211所传递的承重力的受力平面100与轮轴11之间间隔预定距离d。预定距离d可通常设置为3-15厘米，通常可选的为3、5、8、10或15厘米。如图6所示，承重基体211设置有对接腔体2112，两个承重基体211通过各自的对接腔体2112相对接，且由一长轴筒213贯穿两个对接腔体2112内部，长轴筒213两端通过限位件210限位于对接腔体 2112中。
具体的，仍如图5所示，从承重基体211向悬挂架212的方向，悬挂架212沿轮轴11径向的剖面呈W型，悬挂架212包括：与承重基体211相装配并设置于投影线一侧的第一受力部21221和第二受力部21222，以及，以投影线为对称轴设置于投影线另一侧的、分别与第一受力部21221和第二受力部21222形成轴对称关系的第三受力部21223和第四受力部21224。
在运动时，车轮组件1转动时，轮轴11不会跟随车轮组件1整体转动而转动，在踏板组件21发生摆动时，轮轴11会跟随踏板组件21摆动而摆动。
这样，用户踏上踏板组件21后所产生的承重力会依次通过承重基体211、悬挂架212传递到轮轴11上，由于上述受力平面100与轮轴11之间间隔预定距离d，悬挂架212会产生减震作用，从而提高用户的舒适感，同时也能保护轮轴11；另外，抬高了承重基体211以及附着于其上的部件，使其不易碰触到地面上较陡的地方，保护部件及人身安全。
为了保证部件坚固耐用，踏板组件21一般采用硬质金属材料，如钢材或硬质铝合金等。
如图8-10所示，长轴筒213与每个对接腔体2112的内壁之间设置有滚动轴承214，滚动轴承214在本实施例中为滚针轴承。滚针轴承包含：轴承外环2141、轴承内环2142，以及设置于轴承外环2141与轴承内环2142之间的滚针2143。轴承外环2141与对接腔体2112内壁相接触，轴承内环2142与长轴筒213的外壁相接触。这样，滚动轴承214可保证长轴筒213与对接腔体2112内壁之间间隙的均匀性，较长轴筒213与对接腔体2112直接套接的应用方式，转动转向动作更为灵活，也就是说，长轴筒213与对接腔体2112直接套接而省去滚动轴承214也是一种实施方式；且避免了长轴筒213与对接腔体2112内壁长期摩擦氧化，进一步使转动转向动作更为灵活。限位件210为卡簧，长轴筒213设置有供卡簧卡设的卡槽2131。
上述踏板组件21还包括：脚踏件215、设置于承重基体211与脚踏件215之间的微动开关216及回复件217。脚踏件215可包括：匹配设置的脚踏板2151及垫片2152，垫片2152直接与后续的动作簧片2162接触动作。如图11所示，微动开关216包括：开关座2161，以及设置于开关座2161上、在脚踏件215的抵接压力作用下产生形变的动作簧片2162。回复件217位于承重基体211与脚踏件215之间以在脚踏件215撤去所施加的抵接压力作用时使动作簧片2162回 复形变前的状态。在本实施例中，开关座2161固定于承重基体211上，动作簧片2162的固定部与开关座2161相固定、游离部可与脚踏件215相抵接。开关座2161通过承重基体211上的开关座孔2113与承重基体211相固定，回复件217通过承重基体211上的容置孔2111与承重基体211相固定。而开关座2161上设置有与动作簧片2162相抵接或分离的开关按钮2163。回复件217为金属弹簧。开关座2161通过一子板2164与外部一平衡板4相电连通，从而将微动开关216所产生的电信号发送到平衡板4进行控制处理。采用微动开关216及回复件217的组合可达到如下效果：微动开关216及回复件217的组合对温度适应能力较强，不会产生因温度过低而导致的形变缓慢或无法形变的问题，从而保证整个电动平衡车在低温下也能使用，具有普遍适应性。
平衡板4作为体感系统中获取平衡位置等数据的功能板件，主要附着在悬挂架212上。
另外，在本实施例中，电动平衡车还设置有如下可选配部件：
1、如图7所示位于悬挂架212的容置腔2124内的电池组件5，电池组件5包括有：电池及包覆于电池外部的塑胶电池保护套，从而避免电池直接与外部部件磨损，保证部件及人身安全。
2、与控制电路板3相连以对工作状态进行指示的指示灯6。
3、设置于产品外部的保护装饰壳，其包括：位于脚踏件215一侧的上壳7以及位于悬挂架212一侧的下壳8。
4、承重基体211上设置有蓝牙电路板10，蓝牙电路板10与电池组件5及喇叭9，从而实现通过蓝牙技术播放音乐等声音文件。当然，蓝牙电路板10也可设置在下壳8中。
实施例二：
本实施例与上述实施例区别主要在于：悬挂架212结构的不同。也即在本实施例中：从承重基体211向悬挂架212的方向，受力部2122及连接部2123的组合部分2100沿轮轴11径向的剖面呈圆弧型，支撑部2121沿轮轴11径向的剖面呈环形，且支撑部2121的外表面与组合部分2100的内表面相接，如图12所示。或者，如图13所示，支撑部2121的外表面与组合部分2100的外表面相接，悬挂架212包括：与承重基体211相装配并设置于投影线一侧的第五受力部和第六受力部，以及设置于投影线另一侧的第七受力部。
实施例三：
本实施例与上述实施例区别主要在于：微动开关216设置位置的不同。也即在本实施例中：开关座2161固定于脚踏件215上，动作簧片2162的固定部与脚踏件215相固定、游离部可与承重基体211相抵接。
实施例四：
本实施例与上述实施例区别主要在于：回复件217为弹性金属板，弹性金属板。
实施例五：
本实施例与上述实施例区别主要在于：脚踏件215的结构不同，其可仅包括脚踏板2151而不包括起到缓冲作用的垫片2152。
其它实施例：
踏板组件21可采用硬质塑胶材料来代替硬质金属材料。滚动轴承214可采用滚珠轴承来代替滚针轴承。通过设计承重基体211的形状结构，平衡板4可附着在承重基体211的底部。
当然，上述结构不仅可用在双轮的电动平衡车上，如有可能也可以应用在单轮、三轮等形式的电动平衡车上。
在本说明书的描述中，参考术语“一个实施方式”、“一些实施方式”、“一个实施例”、“一些实施例”、“示例”、“具体示例”、或“一些示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本申请的至少一个实施例或示例中。在本说明书中，对上述术语的示意性表述不一定指的是相同的实施例或示例。而且，描述的具体特征、结构、材料或者特点可以在任何的一个或多个实施例或示例中以合适的方式结合。
以上内容是结合具体的实施方式对本申请所作的进一步详细说明，不能认定本申请的具体实施只局限于这些说明。对于本申请所属技术领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干简单推演或替换。
