参见图 2 ~图 21， 下面通过附图和各个实施例， 对本发明的 技术方案做进一步的详细描述。
首先参见图 2所示，儿童推车包括:具有展开和折叠两种状态的 车架、 设置于的车架前下部的前轮組 4、 设置于的车架后下部的后 轮组 5和将的车架锁定于展开位置下的车架锁定机构。 前轮组 4、 后轮組 5和车架锁定机构都为成对存在、 并且是对称设置。
如图 3、 4、 5所示， 车架包括： 手把管 1、 前脚管 2、 后脚管 3 和关节组件 6。 关节组件 6包括： 上关节 61、 后关节 62、 下关节 63 和关节连杆 64。
上关节 61与手把管 1固定连接， 可以采用螺纹连接、卡扣连接 等方式，并且在上关节 61上设置第一枢接点 A和第二枢接点 B。后 关节 62与后脚管 3固定连接， 并且在后关节 62上设置第三枢接点 C和第四枢接点 D。 下关节 63与前脚管 2固定连接， 并且在下关节 63上设置第五枢接点 E和第六枢接点 F。
笫一枢轴穿过第五枢接点 E与第一枢接点 A，将下关节 63与上 关节 61枢接。第二枢轴穿过第六枢接点 F和第四枢接点 D,将下关 节 63与后关节 62枢接。关节连杆 64的两端分别枢接在第二枢接点 B和枢接第三枢接点 C。 枢接是指分别设置枢接孔， 通过枢轴使部 件可枢转地连接。
在收合、 张开车架的过程中， 手把管 1带动上关节 61绕第一枢 轴转动，关节连杆 64带动后关节 62以及后脚管 3绕第二枢轴转动， ^脚管 3靠近或远离前脚管 2。
其中， 当向前脚管 2方向转动手把管 1收合车架时， 与手把管 1固定连接的上关节 61绕上关节的 A枢接点转动，同时通过关节连 杆 64带动后关节 62和后脚管 3绕后关节 62的 D枢接点转动， 并 使后脚管 3靠近前脚管 2。 张开车架过程时， 收合关节组件之间的 传动关系正好与收合车架时相反， 车架收张过程均能实现无危险夹 手间隙地连动收合。
根据本发明的一个实施例， 下关节 62的 C枢接点与 D枢接点 之间的距离较大，在上关节 61的 A枢接点与下关节 63的 E枢接点 活动枢接后，在上关节 61的 B枢接点与后关节 62的 C枢接点活动 枢接后， 在下关节 63的 F枢接点与后关节 62的 D枢接点活动枢接 后， 使上关节 61与后关节 62之间的距离大于儿童推车安全标准规 定的安全间隙阈值。
本发明的儿童推车安全标准规定的安全间隙阈值， 是指根据国 标或国际标准制定的儿童推车安全标准规定的危险夹手间隙。
连接上关节 61的 B枢接点与后关节 62的 C枢接点的关节连杆 64是紧贴下关节 63与上关节 61的侧面， 且下关节 63与上关节 61 和后关节 62三者之间相对应的面均为圆弧形。
下关节 63、 上关节 61和后关节 62都具有圆弧形的边缘， 在车 架动态连动收张过程中， 在收合关节组件之间完全不存在危险夹手 间隙。
根据本发明的一个实施例， 收合关节组件为左右对称性设计， 单侧收合关节组件的下关节 63和关节连杆 64均为对称使用， 收合 关节组件的材庸为高强度塑股件、 或钢制或铝合金的饭金件。
根据本发明的一个实施例， 在前脚管 2与后脚管 3之间没有连 杆连接， 避免了收张过程存在剪手和夹手的可能。
根据本发明的一个实施例， 上关节 61的下部为圆弧形， 并且， 在上关节 61的下部设置弧形阻挡部件，弧形阻挡部件的宽度大于下 关节 63圆弧形边缘的宽度。 其中， 在上关节 61绕第一枢轴朝向后 脚管 3转动的过程中，下关节 63的圆弧形边缘表面与弧形阻挡部件 表面接触， 使手把管 1被限制在设定的位置。
本发明的儿童推车的工作原理是： 向前脚管方向转动手把管收 合车架时， 与手把管固定连接的上关节绕上关节的 A枢接点转动， 同时通过关节连杆带动后关节和后脚管绕后关节的 D枢接点转动， 并使后脚管靠近前脚管， 张开车架的过程， 收合关节组件之间的传 动关系正好与收合车架时相反， 车架收张过程均能实现无危险夹手 间隙连动收合。
连接上关节 2枢接点与后关节 1枢接点的关节连杆是紧贴下关 节与上关节侧面的， 且下关节与上关节和后关节三者之间相对应的 面均为圆弧形， 因此上关节与下关节和后关节在车架动态连动收张 过程中完全不存在危险夹手间隙。 在前脚管与后脚管之间不再需要 连杆连接， 避免了收张过程存在剪手和夹手的可能。
如图 6、 7、 8、 21所示， 所述车架锁定机构包括： 锁销 65、 第 一弹性元件 66、 第二弹性元件 67、 前脚管塞 68、 牵引件 69、 解锁 踏板 70和锁销阻挡件 60。
前脚管塞 68设置在前脚管 2内， 且与上关节 61的下端相对设 置； 前脚管塞 68的上部设置导槽， 锁销 65设置在导槽内， 在导槽 底部和锁销 65之间设置第一弹性元件 66。 锁销 65的下端与牵引件 69的一端固定连接，牵引件 69的另一 端穿过设置在导槽底部的通孔和后脚管 3， 并与解锁踏板 70固定连 接， 解锁踏板 70枢接在后脚管 3上。
在前脚管塞 68的上端设置槽口， 在槽口内装设锁销阻挡件 60。 锁销阻挡件 60的上端与上关节 61的下端相对设置，在上关节 61的 下端设置突出的第一阻挡部位。
锁销阻挡件 60的中段与第二弹性元件 67通过第三枢轴与前脚 管塞 68活动枢接， 并且， 第二弹性元件 67的一端与锁销阻挡件 60 固定连接。
在所述锁销 65的中段上部设置凸台阻挡部，在所述凸台阻挡部 的两侧分别设置第一避让槽和第二避让槽； 其中，所述第二避让槽相 对于所述第一避让槽靠近所述第一弹性件 66;
锁销 65的上端为弧形斜面，并设置与第一 P且挡部位相配合的第 二阻挡部位。
在车架展开过程中， 第一阻挡部位接触锁销 65 上端的孤形斜 面， 压缩第一弹性件 66。 在第一阻挡部位经过锁销 65上端的弧形 斜面后， 第一阻挡部位顶起锁销阻挡件 60的上端， 锁销阻挡件 60 克服第二弹性元件 67的弹力绕第三枢轴转动， 锁销阻挡件 60的下 端向锁销 65靠近。
在车架完全展开时， 在第一弹性件 66的弹力作用下， 锁销 65 向外伸出，正好落在上关节 61下端的卡合面下，将第一阻挡部位卡 在锁销阻挡件 60的上端和第二阻挡部位之间， 锁销阻挡件 60的下 端落入所述锁销 65的第二避让槽中，所述锁销 65阻挡上关节 61使 其不能绕与下关节 63的枢接点向上转动， 即上关节 61向上转动被 锁销 65的卡合面限制， 同时上关节 61向下转动又被宽出的弧形阻 挡部阻挡， 车架被锁定。
在收合车架时， 拉动牵引件 69， 压缩第一弹性件 66, 锁销 65 向导槽内收缩，在拉动并克服所述锁销 65的凸台阻挡部与所述锁销 阻挡件 60的下端的摩擦阻力后， 所述锁销阻挡件 60的下端落入所 述锁销 65凸台阻挡部一侧的第一避让槽中， 限制锁销 65伸出， 同 时所述第二阻挡部与所述第一阻挡部脱离，使所述上关节 61成为不 受阻挡的可转动状态。 但由于没有转动所述上关节 61， 所述上关节 61的下端仍然顶住所述锁销阻挡件 60的上端， 使所述锁销阻挡件 60的下端继续阻挡所述锁销 65的凸台阻挡部； 其中， 转动所述上 关节 61，使所述上关节 61幹放对所述锁销阻挡件 60的上端的阻挡， 所述锁销阻挡件 60在所述第二弹性元件 67弹力的作用下绕所述第 三枢轴转动，使所述锁销阻挡件 60的下端离开所述凸台阻挡部， 所 述锁销 65被释放， 在所述第一弹性元件 66作用下弹出， 回到设定 位置。 第二弹性元件 67可以为扭簧或弹性片。
根据本发明的一个实施例，在锁销 65的中段中间开设槽孔， 第 四枢轴穿过槽孔和前脚管塞 68固定连接，其中， 锁销 65的伸缩行程 为槽孔的长度。
如图 9 - 20所示， 座位支撑组件包括： 换向座位卡口 72、 卡口 支撑座 71和卡口支撑连杆 73。 换向座位卡口 72与卡口支撑座 71 通过第三枢轴枢接在下关节 63上， 并且， 卡口支撑座 71设置在换 向座位卡口 72和下关节 63之间。 换向座位卡口 72与卡口支撑座 71都能够绕第三枢轴转动。
卡口支撑连杆 73的两端分别与卡口支撑座 71和后脚管 3枢接。 在换向座位卡口 72的侧面设置支撑部位 721 , 支撑部位 721与在前 脚管 2上设置的支撑点 631相配合。
在车架完全展开的状态下， 支撑点 631支撑支撑部位 721， 使 换向座位卡口 72不能转动。在卡口支撑座 71上设置第一定位孔 711 和第二定位孔 712， 换向座位的卡脚上设有与第一定位孔 711和第 二定位孔 712相配合的定位柱 74。
其中， 第二定位孔 712为封闭定位孔， 第一定位孔 711为侧壁 开放的开放孔，开放孔与换向座位卡口 72结合形成一个封闭的定位 孔。
在换向座位向后脚管方向插入换向座位卡口 72、 定位柱 74卡 入第二定位孔 712的状态下， 在收合车架时， 后脚管 3通过卡口支 撑连杆 73带动卡口支撑座 71绕与下关节 63的枢接点转动，第二定 位孔 712锁定定位柱 74， 使换向座位的卡脚随卡口支撑座 71转向 后脚管 3方向。
在换向座位向前脚管方向插入换向座位卡口 72、 定位柱 74卡 入第一定位孔 711的状态下。 收合车架时， 后脚管 3向前脚管 2靠 近， 后脚管 3通过卡口支撑连杆 73带动卡口支撑座 71绕与下关节 63的枢接点转动， 使卡口支撑座 71带动换向座位卡口 72向后脚管 3方向转动， 使前脚管 2的支撑点 631远离换向座位卡口 72的支撑 部 721， 由于第一定位孔 711为侧壁开放的开放孔， 并且，换向座位 卡口 72进行了转动，使换向座位卡口 72与换向座位成活动状态， 换 向座位靠自身重量自动靠近前脚管。
如图 17所示，换向座位向前脚管方向插入换向座位卡口、后收 合车架、 卡口支撑连杆驱动卡口支撑座转动， 使换向座位卡口远离 前脚管支撑点呈现活动状态， 把换向座位的靠背前翻后， 换向座位 的重心前移， 使活动的换向座位卡口向前转动。
如图所示， 换向座位向前脚管方向插入换向座位卡口、 后收合 车架、 卡口支撑连杆驱动卡口支撑座转动， 由于卡口支撑座的定位 孔带动换向座位卡脚的定位柱， 使换向座位卡口随换向座位支撑座 转向后脚管， 在换向座位的靠背后翻折合后靠近后脚管。
根据本发明的一个实施例， 手把管、 前脚管、 后脚管的材质都 为钢或铝合金。 其中， 手把管、 前脚管、 后脚管都由一条一体成型 管折弯成型。
本发明中的"第一"、 "第二，，等仅仅用于描述上的区别， 并没有 特殊的含义。
本发明中的"上端"、 "下端"、 "前"、 "后"等是对应于说明书附 图的方位进行描述。
本发明的儿童推车克服了夹手的缺陷， 让消费者在收张车架过 程中均不会受到夹手和剪手伤害。
最后应当说明的是:以上实施例仅用以说明本发明的技术方 案而非对其限制； 尽管参照较佳实施例对本发明进行了详细的说 明， 所属领域的普通技术人员应当理解： 依然可以对本发明的具 体实施方式进行修改或者对部分技术特征进行等同替换； 而不脱 离本发明技术方案的精神， 其均应涵盖在本发明请求保护的技术 方案范围当中。
