技术领域
本 申请 涉及平衡车 技术领域 。
背景技术
平衡车，又叫体感车、思维车、摄位车、扭扭车等。其运作原理主要是建立在一种被称为'动态稳定'的基本原理上，利用车体内部的陀螺仪和加速度传感器来判断车身所处的姿势状态，透过精密且高速的中央微处理器计算出适当的指令后，驱动马达来做到平衡的效果。
平衡车通常包括有两个相连的主机架、驱动电池、控制电路板、轮毂电机等，驱动电池安装在其中一个主机架的下端，控制电路板则是安装在另一个主机架的下端，两个轮毂电机分别位于上述相连的主机架的外端位置的车轮内部。由于驱动电池与控制电路板之间需要导线连接，控制电路板与两个轮毂电机之间也需要导线连接，因此导线需要从上述两个主机架之间通过。
上述两个主机架之间一般是由连接轴连接，为方便走线，连接轴一般是设置成空心的圆管状，以使得导线可以由连接轴中心的通孔穿过。由于连接轴的主体形状一般呈圆柱形，平衡车在运行过程中，随着主机架的微幅摆动，连接轴通常会产生连续的转动，进而有可能带动其内部的导线同时转动，最终有可能导致几股导线扭转在一起最终断裂。

由图 2 主机架的正面示意图，和图 3 主机架背面示意图可以看出，连接部 1 主要有两部分构成，一部分是大致呈圆柱形的柱状体 11 ，在柱状体 11 内部垂直于横截面的方向设置有连接孔 12 ，连接孔 12 大致位于柱状体 11 的中心位置，连接部 1 上沿连接孔 12 的长度方向设置有孔壁 15 ，孔壁 15 的上端设置有加强筋 16 ，加强筋 16 连接柱状体 11 和孔壁 15 ，以增加连接部 1 的强度，同时减轻连接部 1 重量。
结合图 2 、图 4 和图 5 所示，在其中一主机架 100 的连接部 1 上设置有导线管 14 ，具体而言，所述导线管 14 是设置在柱状体 11 的端面 17 上，且导线管 14 内部的管孔（未标号）穿透柱状体 11 ；同时在另一主机架 100 的连接部 1 上的相应位置设置有导线孔 13 ，两个所述主机架 100 连接时，导线管 14 位于导线孔 13 内，导线管 14 的管孔（未标号）穿透于上述柱状体 11 ，且导线管 14 的管孔的截面积大于导线端头的连接器的截面积，进而使导线以及连接器可以顺利地从导线管 14 的管孔中穿过，进而实现方便走线的功能。
在本实施例中，在上述两个主机架 100 上分别设置有导线孔 13 和导线管 14 ，导线孔 13 和导线管 14 在连接孔 12 的两端大致呈对称设置。当两个主机架 100 连接时，导线管 14 位于所述导线孔 13 内，且其中一导线管 14 和导线孔 13 所在的位置与另一导线管 14 和导线孔 13 的位置可相对于后续介绍的连接轴 2 的轴线呈对称分布。当然，导线孔 13 和导线管 14 的数量以及结构形式并不以此为限，在其他的一些实施方式中，可以在一个主机架 100 上只设置一个导线孔 13 ，在另一个主机架上的相应位置设置一个导线管 14 ；或者是在一个主机架 100 上同时设置两个导线孔 13 ，在另一个主机架 100 上的相应位置同时设置两个导线管 14 。导线孔 13 和导线管 14 也可以是其他形状、数量及位置，例如形状为圆形，数量为三个，围绕连接孔 12 呈三角形分布，只要导线孔 13 比导线管 14 大，不会阻挡两个主机架 100 在限定的转动角度内转动即可。
如图 4 和图 5 所示，导线孔 13 在连接部 1 的横截面的大致呈部分环形，其可以由多个圆弧形连接而成的结构，同时导线管 14 在连接部 1 的横截面的大致呈部分环形，其可以由多个圆弧形连接而成的结构。具体而言，按照图 4 所示的方向，导线管 14 的横截面的左右两侧是由两个同圆心的圆弧组成，上下两侧则是由两个半圆组成，其中上述两个同圆心的圆弧的弧度可为 5~45 °，优选为 15~25 °，且圆心位于连接孔 12 的轴心线上。
同理，按照图 4 所示的方向，导线孔 13 的横截面的左右两侧是由两个同圆心的圆弧组成，上下两侧则是由两个半圆组成，其中上述两个同圆心的圆弧的弧度可为 6~90 °，优选为 28~60 °，且圆心位于连接孔 12 的轴心线上，同时需要保证导线管 14 横截面上沿圆弧方向的弧度小于导线孔 13 横截面上沿圆弧方向的弧度。
通过上述可知，构成导线孔 13 横截面的圆弧的圆心位于连接孔 12 的轴线上，且构成导线管 14 的横截面的圆弧的圆心位于连接孔 12 的轴线上，当然，连接孔 12 的轴线和后续介绍的连接轴 2 的轴线重合。所述导线管 14 横截面上沿圆弧方向的长度，小于导线孔 13 横截面上沿圆弧方向的长度。通过此设计，两个主机架 100 连接时，可以限定两个主机架 100 的扭转角度。本实施例中，可以限定两个主机架 100 的极限扭转角度为 20 °，即两个主机架 100 之间的扭转角度范围为 0~20 °。
上述主要说明了主机架 100 端头位置连接部 1 的具体结构，以下将对两个主机架 100 的连接方式进行介绍。
如图 6 和图 7 所示，在本发明的一个实施例中，两个主机架 100 之间可以通过连接轴 2 连接，其中连接轴主要包括螺杆 21 ，垫片 22 ，轴套 23 和螺母 24 ，其中，垫片 22 的数量为 3 个，轴套 23 的数量为 2 个，螺杆 21 和螺母 24 均为 1 个。
具体实现主机架 100 的连接时，上述轴套 23 以及垫片 22 套在螺杆 21 上，共同穿过两个主机架 100 上的连接孔 12 ，最后将螺母 24 拧紧在螺杆 21 的端头实现两个主机架 100 的连接。
所述实施例中，螺杆 21 的直径与轴套 23 的直径配合，同时轴套 23 的直径与连接孔 12 的直径配合，螺杆 21 可以设置成实心体，当然也可以设置成空心体，其中，连接孔 12 的直径取值范围可以为 8~30mm 。
另外，回见图 2 ，上述主机架 100 的连接部上分别设置有端面 17 ，当两个所述主机架 100 连接时，所述两个连接部 1 的端面 17 间的距离为 0.5~8 毫米，另外，导线管 14 可以设置成垂直于端面 17 。
本申请实施例提供的平衡车走线装置， 通过在主机架的端头位置设置导线孔和导线管，方便导线从导线管的内部穿过；导线管和导线孔在平衡车工作过程中只是发生微幅的摆动，不会发生旋转，进而避免内部的导线扭转发生断裂，防止导线损坏。 另外，通过设置导线管和导线孔，当两个主机架连接时，可以更方便地实现两个主机架之间的定位，进而再利用连接轴将两个主机架连接。最后，导线管横截面上沿圆弧方向的长度小于述导线孔横截面上沿圆弧方向的长度，在平衡车工作过程中起到限定主机架扭转角度的作用。
此外，可以理解，在当 导线孔和导线管之间的配合结构具有足够强度时，还可以省略 连接轴的使用。
以上仅为本申请的实施例而已，并不用于限制本申请。对于本领域技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原理之内所作的任何修改、等同替换、改进等，均应包含在本申请的权利要求范围之内。
