图 1-6 所示为本发明的一种实施例的一种儿童摇摆转向车，图 7-14 所示的儿童摇摆转向车为本发明的一种实施例的几种可选的变换方式。
参照图 1-6 所示，儿童摇摆转向车，包括车架 11 、座位 12 、车轮 13 、转向轮 14 、转向机构及辅轮 15 。座位 12 设置于车架 11 上用于供儿童乘坐。车轮 13 和转向轮 14 前后间隔设置于车架 11 底部，其中车轮 13 可设于车架 11 前部作为前轮而转向轮 14 设于车架 11 后部作为后轮，或转向轮 14 设于车架 11 前部作为前轮而车轮 13 设于车架 11 后部作为后轮。转向轮 14 具体通过转向机构连接于车架 11 ，转向机构用于在儿童身体向左或向右倾斜时使转向轮 14 随之向左或向右转向。车架 11 的左右两侧部分别设有至少一个辅轮 15 ，在儿童摇摆转向车转向时着地。
本实施例中，车轮 13 和转向轮 14 的数量之和大于或等于三，且车轮 13 的底部与转向轮 14 的底部均位于同一个平面内（如地面），也就是说，车轮 13 和转向轮 14 着地对儿童摇摆转向车形成稳定支撑。辅轮 15 位于车轮 13 及转向轮 14 的外侧，即设于车架 11 左侧的辅轮 15 位于车轮 13 及转向轮 14 的左侧，设于车架 11 右侧的辅轮 15 位于车轮 13 及述转向轮 14 的右侧；至少在儿童摇摆转向车转向时，左侧或右侧的辅轮 15 的底部与车轮 13 的底部及转向轮 14 的底部处于同一个平面内，使得转向时，左侧或右侧的辅轮 15 也着地，和车轮 13 、转向轮 14 一起对儿童摇摆转向车形成稳定的支撑，避免侧翻。具体到本实施例中，车轮 13 的数量为一个且设于车架 11 后部，转向轮 14 的数量为两个且设于车架 11 前部，车架 11 的左右两侧分别设有一个辅轮 15 ；当儿童摇摆转向车在直行时，车轮 13 和两个转向轮 14 着地，就能对车身形成三点稳定支撑，此时，辅轮 15 的底部高于车轮 13 底部及转向轮 14 底部所在平面，如图 1 和 2 所示；当儿童通过身体向左倾斜来使儿童摇摆转向车转向时，车架 11 及座位 12 向左侧或右侧倾斜，左侧或右侧的辅轮 15 着地，和车轮 13 、转向轮 14 一起对车身进行支撑，如图 6 所示的向左转向的示意图。
还需要说明的是，该儿童摇摆转向车中，转向轮 14 和车轮 13 二者中心的间距 d 为 400-550mm ，如图 2 所示。本实施例中，转向轮 14 的中心具体是指两侧转向轮 14 的几何中心的连线的中点，车轮 13 的中心是指车轮 13 的几何中心。而在另一些实施中，若车轮数量为多个，则车轮的中心是指各车轮几何中心连线的中点。当转向轮 14 和车轮 13 二者中心的间距 d 设定为 400-550mm 时，使得转向轮 14 与车轮 13 的轮距较小，转弯半径随之减小，在车速较快的时候增强转弯刺激性，提高了驾驶乐趣。前后轮间距 d 为 400mm 时需采用自带电机的驱动轮作为车轮，本实施例中采用驱动机构，前后轮间距 d 在 500mm 左右。
转向机构具有多种形式。图 3-5 示出了本实施例采用的一种转向机构，转向轮 14 之间通过轮轴 140 连接，转向机构包括固定连接于轮轴 140 的转向座 16 、固定连接于车架 11 的固定座 17 ，转向座 16 与固定座 17 通过固定在固定座 17 上的转轴 171 相转动连接，转轴 171 沿前后方向或上下方向延伸且转轴 171 的轴心线与水平面之间构成锐角，如图 2 所示，转轴 171 具体为自前至后逐渐向下倾斜。当儿童身体向左或向右倾斜时，在转轴 171 的作用下，转向座 16 相对固定座 17 转动，轮轴 140 随之转动，从而使得转向轮 14 转向。
该转向机构还包括用于使儿童摇摆转向车从转向复位到直行的复位装置，复位装置具体包括压簧 18 。压片 172 固定设置在固定座 17 上，优选的，压片 172 固定连接在转轴 171 的下端部，转向座 16 位 12 于压片 172 和固定座 17 之间，压簧 18 的一端部和转向座 16 相接而另一端部和压片 172 相接，从而顶设于压片 172 和转向座 16 之间。当转向座 16 相对固定座 17 转动时，压簧 18 被压缩；当转向完成后，在压簧 18 弹性力的作用下使转向座 16 反向转动，逐渐复位到该儿童摇摆转向车直行时的状态。
转向座 16 上设有凸部 160 ，固定座 17 上设有凹部 170 ，凸部 160 与凹部 170 相配合，用于对转向座 16 的转动进行限位。凸部 160 可摆动地插设于凹部 170 中，凹部 170 具有一对限位面 170a 和 170b ，凸部 160 具有一对分别位于其相对两侧且与所述一对限位面 170a 和 170b 分别相配合的侧表面 160a 和 160b ，其中一个限位面 170a 和一个侧表面 160a 相对而另一个限位面 170b 和另一个侧表面 160b 相对，一对限位面 170a 和 170b 之间的夹角大于一对侧表面 160a 和 160b 之间的夹角，从而允许凸部 160 在一对限位面 170a 和 170b 摆动，直至凸部 160 的一侧表面 160a 或 160b 和对应的限位面 170a 或 170b 相贴合时，转向座 16 停止转动。优选地，所述一对限位面 170a 和 170b 对称设置，所述一对侧表面 160a 和 160b 对称设置。
该儿童摇摆转向车是一种儿童电动车，通过电机驱动行驶。如图 2 所示，该儿童摇摆转向车还包括用于驱动车轮 13 转动的驱动机构，驱动机构具体包括电机 131 ，连接于电机 131 和车轮 13 之间的传动组件 132 。传动组件 132 包括链条、皮带、齿轮等。车轮 13 可以为儿童摇摆转向车的前轮，也可以为后轮，对应地，该儿童电动车可以采用前轮驱动的方式，也可以采用图 1-6 所示的后轮驱动的方式。
车架 11 具体包括车架本体及两个自车架本体分别向左右两侧延伸的扶手架 111 ，辅轮 15 设于扶手架 111 的底部。图 1-6 所示的实施例中，辅轮 15 具体采用定向轮。
图 7 、 8 示出了本实施例的另一种儿童摇摆转向车，辅轮 15 为球形万向轮；车轮 13 设于车架 11 后部作为后轮，后轮由电机驱动，采用后轮驱动的方式。
图 9 、 10 示出了本实施例的第三种儿童摇摆转向车，辅轮 15 为球形万向轮；车轮 13 设于车架 11 前部作为前轮，前轮由电机 131 驱动，采用前轮驱动的方式。
图 11 、 12 示出了本实施例的第四种儿童摇摆转向车，辅轮 15 为偏心万向轮；车轮 13 设于车架 11 后部作为后轮，后轮由电机驱动，采用后轮驱动的方式。
图 13 、 14 示出了本实施例的第五种儿童摇摆转向车，辅轮 15 为偏心万向轮；车轮 13 设于车架 11 前部作为前轮，前轮由电机 131 驱动，采用前轮驱动的方式。
本实施例提供的儿童摇摆转向车，在行驶过程中需要转向时，坐在座位 12 上的儿童向左或向右倾斜身体，给转向机构施加外力，转向座 16 相对固定座 17 转动，转向轮 14 向左或向右转向，实现转向功能；在转向时，随着车身向左或向右倾斜，左侧或右侧的辅轮 15 着地，配合车轮 13 及转向轮 14 对车身形成稳定支撑，避免侧翻，提高转向时的稳定性，使用较安全。
图 15-21 所示为本发明的另一种实施例。参照图 15-21 所示，本实施例提供的一种儿童摇摆转向车，包括车架 21 、座位 22 、车轮 23 、转向轮 24 、转向机构及辅轮 25 。车架 21 主要由车架本体 210 和扶手架 211 两部分组成，车架本体 210 可左右转动地连接于扶手架 211 上。具体地，车架本体 210 通过第一枢轴 213 可转动地连接于扶手架 211 上，第一枢轴 213 沿前后方向延伸且平行于水平面，从而使得车架本体 210 可绕第一枢轴 213 沿图 15 中箭头所示方向向右摆动（如图 16 所示）或向左摆动（如图 17 所示）。座位 22 设置于车架本体 210 上用于供儿童乘坐。车轮 23 和转向轮 24 前后间隔设置。转向机构用于在儿童身体向左或向右倾斜时使转向轮 24 随之向左或向右转向。扶手架 211 的左右两侧部分别设有至少一个辅轮 25 ，图 15-21 所示的实施例中采用偏心万向轮作为辅轮 25 。
扶手架 211 位于前后设置的转向轮 24 和车轮 23 之间，扶手架 211 的左右两侧部相对车架本体 210 分别向外延伸，从而辅轮 25 位于车轮 23 及转向轮 24 的外侧，即设于扶手架 211 左侧部的辅轮 25 位于车轮 23 及转向轮 24 的左侧，设于扶手架 211 右侧部的辅轮 25 位于车轮 23 及述转向轮 24 的右侧，无论该儿童转向车直行还是转向，两侧的辅轮 25 始终着地。本实施例中，车轮 23 的数量为一个并设于车架本体 210 底部，转向轮 24 通过转向机构连接于车架本体 210 底部，转向轮 24 、辅轮 25 的数量分别为两个。当儿童摇摆转向车在直行时，车轮 23 的底部、两个转向轮 24 的底部及两个辅轮 25 的底部均位于同一个平面内（如地面），车轮 23 、转向轮 24 、辅轮 25 均着地对儿童摇摆转向车形成稳定支撑。而当儿童摇摆转向车在转向时，车轮 23 、至少一侧的转向轮 24 及两个辅轮 25 依然位于上述平面内，车轮 23 、至少一侧的转向轮 24 及两个辅轮 25 着地，仍然能够对儿童摇摆转向车形成稳定支撑。也就是说，无论直行还是转向，两侧的辅轮 25 和车轮 23 始终着地，形成一个稳定的三角形，对儿童摇摆转向车形成稳定的支撑，避免侧翻，使得整车运行平稳。
参见图 19-21 所示，本实施例的转向机构，包括转向座 26 、固定连接于车架 21 的固定座 27 ，两侧的转向轮 24 之间通过轮轴 240 连接，转向座 26 固定连接于轮轴。转向座 26 与固定座 27 通过固定在固定座 27 上的转轴 271 相转动连接，转轴 271 沿前后方向或上下方向延伸且转轴 271 的轴心线与水平面之间构成锐角，如图 19 所示，转轴 271 具体为自前至后逐渐向下倾斜。当儿童身体向左或向右倾斜时，在转轴 271 的作用下，转向座 26 相对固定座 27 转动，轮轴 240 随之转动，从而使得转向轮 24 转向。转向机构还包括固定连接于转轴 271 下端部的压盖 272 ，转向座 26 被限制在固定座 27 和压盖 272 之间。
该转向机构还包括用于使儿童摇摆转向车从转向复位到直行的复位装置，复位装置具体包括一对弹簧，本实施例中的弹簧具体选用压簧 28 。固定座 27 具有腔体 270 ，转向座 26 具有一个向外延伸的自由端 260 ，该自由端 260 可摆动地设于所述腔体 270 中。该自由端 260 位于上述一对压簧 28 之间，压簧 28 设于自由端 260 和腔体 270 的内壁之间。具体对应于图 7 中，左侧的压簧 28 设于腔体 270 的左侧内壁和自由端 260 的左侧表面之间，右侧的压簧 28 设于腔体 270 的右侧内壁和所述自由端 260 的右侧表面之间。当转向座 26 相对固定座 27 转动时，一侧的压簧 28 被压缩；当转向完成后，在该侧压簧 28 弹性力的作用下使转向座 26 反向转动，逐渐复位到该儿童摇摆转向车直行时的状态。该转向机构能够通过两侧的压簧 28 使儿童摇摆转向车复位到直行状态，同时还能对转向角度进行限位，相比现有技术中转向机构，具有结构简单的优点。
该儿童摇摆转向车具体为一种儿童电动车，通过电机驱动行驶。如图 18-20 所示，该儿童摇摆转向车还包括用于驱动车轮 23 转动的驱动机构，驱动机构具体包括电机 231 ，连接于电机 231 和车轮 23 之间的传动组件 232 。车轮 23 可以为儿童摇摆转向车的前轮，也可以为后轮，对应地，该儿童电动车可以采用图 15-20 所示的前轮驱动的方式，也可以采用后轮驱动的方式。
本实施例提供的儿童摇摆转向车，摇摆转向的实现是通过扶手架 211 和车架本体 210 的第一枢轴 213 连接，使得第一枢轴 213 作为转点，可实现车架本体 210 相对水平面左右摆动；再通过转向机构的转轴 1 的相互扭动，来实现驾驶中的转向。在行驶过程中需要转向时，坐在座位 22 上的儿童向左或向右倾斜身体，给转向机构施加外力，转向座 26 相对固定座 27 转动，转向轮 24 向左或向右转向，实现转向功能；在转向完成后，压簧 28 的复位力驱动转向座 26 复位，使儿童摇摆转向车复位到直行状态；在直行及转向时，两侧的辅轮 25 始终着地，配合车轮 23 及转向轮 24 对车身形成稳定支撑，避免转向时随着车身向左或向右倾斜所导致的侧翻，提高整车运行的稳定性，使用较安全。
