Description

一种平衡车 技术领域
本发明涉及平衡车技术领域，特别涉及一种平衡车。
背景技术
平衡车，又叫体感车、思维车或摄位车等。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)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。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明的一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
需要说明，若本发明实施例中有涉及方向性指示(诸如上、下、左、右、 前、后……)，则该方向性指示仅用于解释在某一特定姿态(如附图所示)下各部件之间的相对位置关系、运动情况等，如果该特定姿态发生改变时，则该方向性指示也相应地随之改变。
另外，若本发明实施例中有涉及“第一”、“第二”等的描述，则该“第一”、“第二”等的描述仅用于描述目的，而不能理解为指示或暗示其相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括至少一个该特征。另外，各个实施例之间的技术方案可以相互结合，但是必须是以本领域普通技术人员能够实现为基础，当技术方案的结合出现相互矛盾或无法实现时应当认为这种技术方案的结合不存在，也不在本发明要求的保护范围之内。
以下结合图1-图12及相关实施例对本发明方案做进一步阐述。
如图1-图5所示，一种平衡车，包括左支撑轴11、右支撑轴12和车轮2，所述左支撑轴11和所述右支撑轴12的外端均连接有车轮2，所述左支撑轴11和所述右支撑轴12的内端可相对转动地连接；
所述右支撑轴12的内端设有一段小外径部13，所述小外径部13适应性插装在所述左支撑轴11的内端；
所述左支撑轴11的内端侧壁设有一弧状通孔14，设有限位螺栓16的下端穿过所述弧状通孔14与所述小外径部13固定连接，其上端至少高于所述弧状通孔14的下边沿；所述弧状通孔14在其长度方向的两内侧壁分别限定了所述左支撑轴11和所述右支撑轴12相对转动的极限位置。
本技术方案提供一种平衡车中左支撑轴11和右支撑轴12可相对转动地连接的结构，即直接在左支撑轴11的侧壁设置弧状通孔13，该弧状通孔13沿着左支撑轴11和右支撑轴12相对转动的方向呈弧状延伸，右支撑轴12的小外径部13插装在左支撑轴11的内端，插装时向前伸入的距离超过弧状通孔13所处的位置，再将限位螺栓16从外部穿过弧状通孔14与小外径部13固定连接，限位螺栓16的上端可运动的范围被弧状通孔14限制，左支撑轴11和右支撑轴12相对转动时，则限位螺栓16沿弧状通孔13的长度方向在其内往复运动。
需要说明的是，限位螺栓16与弧状通孔14的装配方式，对于限位螺栓 16的上端帽，既可以高出弧状通孔14的外壁面，也可以低于弧状通孔14的外壁面，沉入弧状通孔14的孔壁内，只要限位螺栓16的上端帽的上端面高于弧状通孔14的孔壁下边沿，使得弧状通孔14的孔壁能限制限位螺栓16运动的极限位置即可。而对于限位螺栓16的上帽端宽度，与弧状通孔14的宽度，最佳的尺寸配合为上帽端宽度略小于弧状通孔14的宽度，装配时，限位螺栓16的上帽端侧壁与弧状通孔14的孔壁轻微接触，一方面限定了左支撑轴11和右支撑轴12在轴向上的相对移动，另一方面也增加了左支撑轴11和右支撑轴12相对转动时的摩擦力，更方便对平衡车方向调节的掌控。
优选地，所述左支撑轴11的内端设有供所述小外径部13插装的安装筒部15，所述安装筒部15设有与所述左支撑轴11的轴线相垂直的内壁面，以限定所述小外径部13插入所述左支撑轴11时的极限位置。
本实施例中，左支撑轴11可以为设有两端相通的中心通孔的轴体，而安装筒部15设置在左支撑轴11的前端，其内径大于上述中心通孔的内径，则安装筒部15与中心通孔在变直径过渡的位置形成阶梯端面，该阶梯端面即为与左支撑轴11的轴线相垂直的内壁面，用于限定小外径部13插入所述左支撑轴11时的极限位置；另外的，左支撑轴11可以实心轴体，安装筒部15设置在左支撑轴11的前端，则安装筒部15的底壁面即为与左支撑轴11的轴线相垂直的内壁面，用于限定小外径部13插入所述左支撑轴11时的极限位置，提高装配的稳定性。
优选地，还包括设有两端相通的套筒3，其套设在所述小外径部13的外周，并与所述小外径部13同轴安装在所述左支撑轴11的内端；
所述套筒3的长度小于所述小外径部13的长度，相适应地，所述左支撑轴11的内端设有从左到右依次分布的大直径内筒151和小直径内筒152。
本实施例中在小外径部13的外壁面与左支撑轴11的内壁面之间增加设置了一套筒3，提高左支撑轴11和右支撑轴12连接位置的强度和灵活性。
本实施例提供的一种平衡车，还包括左盖4和右盖5：如图4及图6所示，
所述左盖4包括左上盖41以及与所述左上盖41盖合设置的左下盖42， 所述左支撑轴11的轴杆沿着所述左盖4的长度方向延伸，并与所述左上盖41固定连接；
所述右盖5包括右上盖51以及与右上盖51盖合设置的右下盖52，所述右支撑轴12的轴杆沿着所述右盖5的长度方向延伸，并与所述右上盖51固定连接。
现有技术中为了增强平衡车的强度，会在左盖4和右盖5内分别设置铝板，两铝板相对转动地设置，以实现平衡车方向的调节。
本实施例中，直接舍弃笨重且成本高的铝板，将左支撑轴11和右支撑轴12直接可相对转动地连接，再将左支撑轴11和右支撑轴12分别与左上盖41、右上盖51固定设置，以实现平衡车方向的调节，保证强度的同时，也大大降低了成本和平衡车的整体重量。
优选地，如图4和图5所示，还包括支撑套6，其包括支撑内筒61，所述支撑内筒61套设在所述左支撑轴11和所述右支撑轴12的内端面相交汇的位置；
所述支撑套6的边沿卡装在所述左盖4的右端面与所述右盖5的左端面相交汇的位置。
为了进一步提高装配的强度和紧密型，本实施例中设置支撑套6，左支撑轴11的内端和右支撑轴12可转动连接时端面相抵，支撑内筒61套设在该端面相抵的外部，限制了两者沿径向发生松动，装配稳定；再者，支撑套6的边沿卡装在左盖4的右端面与右盖5的左端面相交汇的位置，优选地，支撑套6呈圆柱状，左盖4的右端侧设有半槽，右盖5的左侧设有半槽，平衡车装配时，左盖4的右端面和右盖5的左端面相抵，两个半槽合并为完整的开口向内的卡装槽，支撑套6的边沿卡装抵接在所述卡装槽内，卡装槽沿着支撑套6的边沿轨迹设置。本实施例中通过一个支撑套6，中部紧凑套设左支撑轴11和右支撑轴12的连接位置，边沿抵接紧凑卡装左盖4和右盖5，一举多得，提高了整个平衡车结构的紧凑和稳定性。
进一步地，所述支撑套6的端面设有水平向外延伸的U型卡角62，所述U型卡角62的开口朝外，所述左盖4和/或所述右盖5设有沿竖直方向延伸的 支撑柱7，所述支撑柱7卡装设置在所述U型卡角62的开口内。
本实施例中，沿竖直方向延伸设置的支撑柱7与支撑套6的U型卡角62卡装，限制了支撑套6沿U型卡角开口朝向的一侧发生水平偏移，提高平衡车内部结构的稳定性。优选地，U型卡角62的数量为两个，两个U型卡角62平行设置在支撑套6的端面。
优选地，为了提高支撑轴与盖体之间连接的稳定性，本实施例中，所述左支撑轴11的轴杆和所述左上盖42的内端面之间、所述右支撑轴12的轴杆和所述右上盖51的内端面之间分别支撑设置有安装座17，分别设有安装螺栓18依次穿过所述左支撑轴11的轴杆及其下方的所述安装座17、所述右支撑轴12的轴杆及其下方的所述安装座17实现固定连接；
优选地，所述安装座17的上端面设有向下凹陷，且能适应所述左支撑轴11和所述右支撑轴12的轴杆卡装的槽体。
对于平衡车左支撑轴11(右支撑轴12)与车轮的具体安装结构，有多种实现形式，其中一个优选的实施方式为，车轮的车轮轴与支撑轴为同一个轴的一体化设置，支撑轴转动则车轮直接跟着一起转动。具体的，如图4及图7所示，所述车轮2包括左车轮21和右车轮22，所述左车轮21的车轮轴沿水平方向向右延伸形成所述左支撑轴11，所述右车轮22的车轮轴沿水平方向向左延伸形成所述右支撑轴12，结构简单，简化了安装方式。
