实施例十二： 如图 20所示， 车底架 4前端固定安装一横向车轮架， 该车轮架的两端各安装一前轮 1。 本实施例的其它内容可参见其它实施例。
实施例十三： 如图 21-26所示， 摇摆式童车包括转向前轮 1、 承载体 2、 推把 3、 驱动轮 13、 差速轮 37。 推把 3与车底架 4固定连接， 车底架 4后部还通过加强杆 19连接推把 3。
承载体 2的前下部设上凸耳 18， 上凸耳 18与摇杆 20的上端转动相连； 车底架 4的前部开有摇摆孔 22， 摇杆 20的下端通过销轴 19转动配合于摇摆孔 22。
差速轮 37与驱动轴 8转动配合， 驱动轮 13与驱动轴 8紧固配合， 驱动轮 13带动驱动轴 8作同步转 动。
承载体 2的后底部开有摇晃孔 11。 驱动轴 8的中部设主动齿轮 5， 两者间通过长键配合。 车底架 4的 后半部设一曲拐轴 14， 曲拐轴 14的两端转动式地配合曲拐轴座 17上， 曲拐轴座 17与车底架 4固定相连。 曲拐轴 14与曲拐 10紧固配合， 曲拐 10与摇晃孔 11通过销轴 21转动配合。 本实施例的偏心轴选用曲拐 轴。 曲拐轴 14的中部设被动齿轮 7， 被动齿轮 7的外径大于主动齿轮 5的外径， 被动齿轮 7与主动齿轮 5 通过惰齿轮 6啮合。 主动齿轮 5和惰齿轮 6外套齿轮架 15， 惰齿轮 6与齿轮架 15间通过销轴转动配合。 同时， 驱动轴 8横穿齿轮架 15， 且齿轮架 15可沿驱动轴 8转动， 并可以沿驱动轴 8的轴向移动。 需转换 承载体 2的运动状态时， 扳动齿轮架 15或移动齿轮架 15， 都可使惰齿轮 6与被动齿轮 7相啮合或脱离。 如图 23-24所示为惰齿轮 6与被动齿轮 7脱离吋的状态。如图 25-26所示为惰齿轮 6与被动齿轮 7啮合时 的状态。 沿驱动轴 8轴向移动齿轮架 15或扳动齿轮架 15， 都可使主动齿轮 5和惰齿轮 6与被动齿轮 7相 脱离， 此吋， 推行童车， 承载体 2不作运动。
承载体 2下部还安装有上弹簧座 32， 与此相对应， 车底架 4安装下弹簧座 34， 上弹簧座 32形成一个 插槽， 下弹簧座 34竖向形成 3-5个 (本例为 4个)不同高度、 倾斜的插槽。 V形弹簧 33的上端转动式地插 于上弹簧座 32的插槽、 下端转动式地插入下弹簧座 34的插槽， 并且 V形弹簧 33的两端部都呈弯钩状， 分别钩住上下弹簧座的另一侧， 以防止其横向脱出。 V形弹簧 33对承载体 2起缓冲及回复作用 , 使承载体 2的运动更加平稳。 并且， 由于下弹簧座 34设有多个插槽， 因此， 可以根据实际使用需求， 将 V形弹簧 33的下端插于某个合适的插槽， 以调整其弹力。
车底架 4与驱动轴 8通过主轴套 16相连， 驱动轴 8与主轴套 16间可相对转动。
锁定钩 46与扳手 47—体成型， 两者的交叉部转动式地套于驱动轴 8。锁定钩 46的端部呈钩状， 而扳 手 47伸向童车后方。 于承载体 2的后下部开有一个锁定孔 48， 该锁定孔 48与锁定钩 47的钩状端部相适 配。 通过转动扳手 47， 可以将锁定钩 46的钩状端部插入或脱离承载体 2的锁定孔 48。 在承载体 2不作运 动的状态下， 摇动扳手 47， 将锁定钩 46的钩状端部插入承载体 2的锁定孔 48， 从而锁定了承载体 2， 承 载体 2便无法摇晃。
通过摇动扳手 47， 使锁定钩 46的钩状端部脱离承载体 2的锁定孔 48， 在此状态下， 推行童车， 驱动 轮 13带动驱动轴 8同步转动， 驱动轴 8又使主动齿轮 5转动， 主动齿轮 5通过惰齿轮 6使被动齿轮 7转 动， 使曲拐轴 14和曲拐 10同步转动， 曲拐 10通过摇晃孔 11使承载体 2作起伏运动。 再结合童车前部摇 摆机构的作用， 最后承载体 2作上下起伏、 前后摇摆有规律的运动。
实施例十四： 本实施例与实施例十三的不同之处在于可调节弹力的弹簧装置。 如图 27、 28所示， 承 载体 2下部安装导杆座 29， 相对应地， 车底架 4上安装导杆套 30， 导杆套 30的中部形成插孔。 导杆 31 的上端前后摆动式地安装于导杆座 29上， 导杆 31外套螺旋弹簧 12， 导杆 31的下端活动式地插入导杆套 30内。 导杆 31的上部设有螺紋并旋入调节螺母 49， 螺旋弹簧 12的上端部顶于调节螺母 49, 螺旋弹簧 12 的下端部顶于导杆套 30上平面。螺旋弹簧 12对承载体 2起缓冲及回复作用，使承载体 2的运动更加平稳。
本实施例的其它内容与实施例十三相同。
实施例十五： 如图 29-31所示， 动感童车包括承载体 2 转向前轮 1、 驱动轮 13、 差速轮 37、 推把 3， 推把 3与车底架 4固定连接， 车底架 4后部还通过加强杆 19连接推把 3， 以加强童车强度。
承载体 2的前下部设上凸耳 18， 上凸耳 18与摇杆 20的上端转动相连； 车底架 4的前部开有摇摆孔 22， 摇杆 20的下端通过销轴 19转动配合于摇摆孔 22。
承载体 2的后底部开有摇晃孔 11。 车底架 4的后半部设一曲拐轴 14 , 曲拐轴 14的两端转动式地配合 曲拐轴座 17上， 曲拐轴座 17与车底架 4固定相连。 曲拐轴 14与曲拐 10紧固配合， 曲拐 10与摇晃孔 11 通过销轴 21转动配合。本实施例的偏心轴采用曲拐轴。驱动轴 8的中部紧固主动链轮 26， 曲拐轴 14紧固 被动链轮 28， 链轮 28的外径大于链轮 26的外径， 两链轮 26、 28间通过链条 25传动。
车底架 4与驱动轴 8通过主轴套 16相连， 驱动轴 8与主轴套 16间可相对转动。
差速轮 37与驱动轴 8转动配合， 驱动轮 13与驱动轴 8转动式配合， 两者间通过设置的离合器连动或 者脱离即不连动。连动时， 驱动轮 13带动驱动轴 8作同步转动。 离合器结构可参见图 30， 駆动轮 13的外 侧面固定设置基座 50， 驱动轴 8的该端外固设离合内圈 51， 驱动轮 13外套于离合内圈 51， 两者间可以相 对转动。 基座 50外侧由弹簧卡圈 55定位， 以防止其外跑。 基座 50上插入一带握柄 54的插销 52， 插销 52外套弹簧 53， 于离合内圈 51上也形成四个插销孔， 其与插销 52相适配， 插销孔外端部各有一条凹槽 56, 插销手柄 54的内端也形成长条形， 其与 槽 56相对应。 当需要驱动轮带动驱动轴转动时， 将插销手 柄 54的内端长条形罢至与凹槽 56相对应位置， 插销 52的内端在内置弹簧 53的弹力作用下伸入离合内圈 51的某个插销孔内， 此时两者连动。 当不需要驱动轮带动驱动轴转动吋， 拔出插销 52并自转 90度后， 由 于插销手柄 54的内端长条形与凹槽 56交错， 插销握柄 54便被插销孔外端部阻挡而使插销 52的内端便不 能插入离合内圈 51的插销孔内。
承载体 2下部还安装有上弹簧座 32， 与此相对应， 车底架 4安装下弹簧座 34， 上弹簧座 32形成一个 插槽， 下弹簧座 34竖向形成 3-5个 (本实施例为 4个)不同高度、 倾斜的插槽。 V形弹簧 33的上端转动式 地插于上弹簧座 32的插槽、 下端转动式地插入下弹簧座 34的插槽， 并且 V形弹簧 33的两端部都呈弯钩 状， 分别钩住上下弹簧座的另一侧， 以防止其横向脱出。 V形弹簧 33对承载体 2起缓冲及回复作用， 使承 载体 2的运动更加平稳。 并且， 由于下弹簧座 34设有多个插槽， 因此， 可以根据实际使用需求， 将 V形 弹簧 33的下端安插于某个合适的插槽， 以调整其弹力。
锁定钩 46与扳手 47—体成型， 两者的交叉部转动式地套于驱动轴 8。锁定钩 46的端部呈钩状， 而扳 手 47伸向童车后方。 于承载体 2的后下部开有一个锁定孔 48， 该锁定孔 48与锁定钩 47的钩状端部相适 配。 通过转动扳手 47， 可以将锁定钩 46的钩状端部插入或脱离承载体 2的锁定孔 48。
通过摇动扳手 47， 使锁定钩 46的钩状端部脱离承载体 2的锁定孔 48， 在此状态下， 合上离合器， 使 驱动轮 13与驱动轴 8连动， 此时推行童车， 驱动轮 13带动驱动轴 8同步转动时， 驱动轴 8又使主动链轮 26转动， 主动链轮 26通过链条 25使被动链轮 28转动， 进而使曲拐轴 14和曲拐 10同步转动， 曲拐 10通 过摇晃孔 11使承载体 2作起伏运动。 再结合童车前部摇摆机构的作用， 最后承载体 2作上下起伏、 前后 摇摆有规则的运动。
当脱开离合器时， 驱动轮 13与驱动轴 8无连动关系， 此时推行童车， 承载体 2不作运动。 在此状态 下， 通过摇动扳手 47， 将锁定钩 46的钩状端部插入承载体 2的锁定孔 48， 从而锁定了承载体 2， 承载体 2便无法摇晃。

本实施例的其它内容与实施例十五相同。

实施例十九： 本实施例的离合器与实施例十五或实施例十六或实施例十七不同， 如图 36所示， 螺母 41旋入驱动轴 8的外端部， 其与驱动轮 13间置入带齿牙的联接齿圈 44， 联接齿圈 44与驱动轴 8间设一 长键 40; 驱动轮 13的外侧面也形成与上述联接齿圈 44相应的齿牙， 两者脱离时， 联接齿圈 44只作沿驱 动轴 8的轴向运动。 通过旋紧或放松螺母 41来推动联接齿圈 44与驱动轮 13间的啮合或脱离， 使驱动轮 13与驱动轴 8的同步转动或脱离， 进而调整承载体 2的状态。
本实施例的其它内容与实施例十五或实施例十六或实施例十七相同。
