Description

技术领域
本发明涉及一种童车， 尤其是一种可折叠童车。
背景技术
现有技术中的可折叠童车通常包括可折叠的车架、设置在车架底 部并对整车提供支撑的车轮、用于在展开车架时将车架锁固的锁机构, 其中，该锁机构可以采用多种机械结构来实现车架的锁定，例如采用 杆件的刚性抵触、挂钩挂接在杆件上等方式。 然而， 上述连接方式在 使用者不小心触碰到或者在遇到颠簸等意外情况时会产生误操作，给 使用者来说造成不便， 对乘坐童车的婴儿来说同样存在风险。
发明内容
本发明的目的在于提供一种折叠安全的可折叠童车。
为达到上述发明目的，本发明所采用的技术方案是：一种可折叠 童车， 它包括前叉及连接于所述的前叉前端的前轮、后叉及连接于所 述的后叉后端的后轮、设置在所述的前叉与所述的后叉之间的伸缩杆、 闭合端与所述的前叉相转动连接的 U形摆杆、一端与所述的 U形摆杆 的闭合端固定连接另一端与所述的后叉转动连接的第二转动连接件， 所述的前叉、后叉、第二转动连接件以及伸缩杆的侧投影构成一个四 边形支撑结构，所述的 U形摆杆的开口端转动连接有推杆，所述的可 折叠童车还包括一个用于锁定或解锁所述的伸缩杆的第一锁件以及 一个用于锁定或解锁所述的第一锁件的第二锁件，只有当所述的第二 锁件处于解锁状态，所述的第一锁件才可以被解锁或者锁定，从而启 动或者关闭所述的四边形支撑结构的折叠动作。
作为本发明进一步的改进,所述推杆包括用于与 u形摆杆连接的 下推杆，所述下推杆至少具有一段空心内腔，所述的下推杆的内腔中 还插接有上推杆。
作为本发明进一步的改进,所述的上推杆与下推杆的连接处设置 有多个用于限定所述的上推杆和下推杆相对位置的档位。
作为本发明进一步的改进,所述的第二锁件设置在所述的 u形摆 杆上，当所述的下推杆向所述的前叉方向转动时所述的第二锁件运动 被触发从而解锁所述的第一锁件。
作为本发明进一步的改进， 所述的伸缩杆为气弹簧。
由于上述技术方案的采用，本发明与现有技术相比具有以下优点： 首先， 由于增加了用于锁定和解锁折叠踏板运动的第二锁件，从 而在使用的过程中， 不会发生如因误碰等操作而致使折叠踏板运动， 进而使童车折叠的问题， 增加了童车安全性；
其次,在折叠操作过程中，首先通过下推杆向前运动到预定位置， 推动二次锁接锁件使折叠踏板解锁，向前推动下推杆至预定位置的动 作足以证明操作者有折叠童车的意图，保证了童车折叠过程的安全性。 附图说明
附图 1为本发明实施例的立体图；
附图 2为本发明实施例的侧视图；
附图 3为本发明实施例的侧视图，图中同时示出了童车的折叠动 作过程。
其中： 1、 上推杆； 2、 下推杆； 3、 第一转动连接件； 4、 U形摆 杆； 5、 前叉； 6、 第一锁件； 7、 伸缩杆； 8、 后叉； 9、 后轮； 10、 前轮； 11、 第二锁件； 12、 第二转动连接件。
具体实施方式
参见附图 1和附图 2 , —种可折叠童车， 它包括前叉 5及连接 于前叉 5前端的前轮 10、后叉 8及连接于后叉 8后端的后轮 9、设置 在前叉 5与后叉 8之间的伸缩杆 7、 闭合端与前叉 5相转动连接的 U 形摆杆 4、一端与 U形摆杆 4的闭合端固定连接另一端与后叉 8转动 连接的第二转动连接件 12 , 前叉 5、 后叉 8、 第二转动连接件 12以 及伸缩杆 7的侧投影构成一个四边形支撑结构，其中第二转动连接件 12采用焊接的方式焊接在 U形摆杆 4的闭合端，前轮 10可以各向转 动以实现童车的转向。
U形摆杆 4的开口端分别转动连接有一个下推杆 2 , 下推杆 2的 另一端的内腔插接有呈 n形的上推杆 1 ,该上推杆 1用于操作者持握 以推动童车，上推杆 1与下推杆 2的连接处设置有多个用于限定上推 杆 1和下推杆 2相对位置的档位，这里，可以设置一个锁定机构以控 制上推杆 1在移动过程中在各档位处的定位。
可折叠童车还包括一个用于用于锁定或解锁伸缩杆 7 的折叠动 作的第一锁件 6 以及一个用于锁定或解锁第一锁件 6的的第二锁件 11 , 第二锁件 11设置在 U形摆杆 4上， 第一锁件 6设置在伸缩杆 7 上并设置为踏板的形状以方便使用者直接通过用脚踩踏来控制；第一 转动连接件 3分为两个部分，其一部分通过紧固螺丝可以固定设置在 U形摆杆 4上， 并且可以调整处于 U形摆杆 4的位置， 其另一部分固 定设置于下推杆 2的下端，这两部分之间设置有一转轴从而实现下推 杆 2和 U形摆杆 4转动连接，当下推杆 2向前叉 5方向转动至一预定 角度， 例如， 下推杆 2与 U形摆杆 4之间的夹角为 0度， 即可触发第 二锁件 11从而解锁第一锁件 6 , 本领域的普通技术人员可以得知， 在这里可以通过多种不同的技术手段来实现预定角度的设定。
在本实施例中，伸缩杆 7为气弹簧，并且一个端部与后叉 8可转 动的连接， 另一个端部与前叉 5的端部接触。
以下结合附图 3详细说明本实施例是如何实现折叠的过程。 首先，向插入下推杆 2的方向推动上推杆 1至底后，向前轮方向 绕第一转动连接件 3转动下推杆 2 ,在下推杆 2绕过 U形摆杆 4转动 过程中， 启动第二锁件 11运动， 进而解锁第一锁件 6;
其次， 踩踏第一锁件 6 , 使 U形摆杆 4绕与前叉 5的转轴向后轮 9方向转动，并且与 U形摆杆 4固定连接的第二转动连接件 12 ,也将 同步地绕第二转动连接件 12与后叉 8的转轴向后轮 9方向转动， 致 使前叉 5、 伸缩杆 7、 后叉 8、 第二转动连接件 12组成的四边形支撑 结构发生折叠动作。
本实施例中的童车的展开过程与此相类似， 在这里不在赘述。 综上所述， 在本实施例中共有 5个折叠转动轴： 下推杆 2与 U 形摆杆 4之间的转动轴、 U形摆杆 4与前叉 5之间的转动轴、 第二转 动连接件 12与后叉 8之间的转动轴、 第二转动连接件 12与前叉 5 之间的转动轴、 伸缩杆 7与后叉 8之间的转动轴， 童车通过上述 5 个转动轴完成对童车的折叠与展开。
以上实施方式只为说明本发明的技术构思及特点， 其目的在于让 熟悉此项技术的人了解本发明的内容并加以实施，并不能以此限制本 发明的保护范围，凡根据本发明精神实质所做的等效变化或修饰，都 应涵盖在本发明的保护范围内。
