Description

一种折叠车及车把折叠总成
本申请要求于2017年03月09日提交中国专利局、申请号为201710138315.6、发明名称为“一种折叠车及车把折叠总成”，以及于2017年03月09日提交中国专利局、申请号为201720226309.1、发明名称为“一种折叠车及车把折叠总成”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及折叠车生产技术领域，更具体地说，涉及一种折叠车及车把折叠总成。
背景技术
随着人们生活水平的提高，生活需求也更加丰富和多样化，适合城市短距离出行且方便携带的折叠车被越来越多的消费者所选择。为了能够实现尺寸的缩小，折叠车的车把也被设计成为了可折叠式，如申请号为：201620450349.X的中国发明专利中，公开了一种把手折叠组件。
该把手折叠组件包括车把手组件，车把手组件包括与龙头支撑臂上端固连的把手连接套及对称安装在把手连接套两端的把手，把手连接套的中部侧壁开设有轴向延伸的开口槽，开口槽的槽口边缘凸出带有夹紧凸缘，夹紧凸缘上安装有将把手锁紧在把手连接套中的锁扣，把手的端部带有轴向延伸的滑槽，把手连接套的两端径向安装有贯穿滑槽的把手旋转轴，把手通过滑槽与把手旋转轴配合可于把手连接套中周向滑动。
该把手折叠组件中，把手锁紧时操作锁扣锁紧，锁扣的锁紧将引发把手连接套的形变，开口槽缝隙变小，从而达到锁紧把手的目的。开口槽缝隙变小时非常容易夹手，容易对用户造成身体伤害，存在安全隐患。
因此，如何能够提供一种结构简单、操作方便且使用安全的把手折叠总成是目前本领域技术人员亟需解决的技术问题。
发明内容
有鉴于此，本发明的目的之一在于提供一种车把折叠总成，以便提高车把 折叠操作便利性，同时能够提升车把折叠操作时的安全性。
本发明的另一目的在于提供一种采用上述车把折叠总成的折叠车。
为实现上述目的，本发明提供如下技术方案：

具体实施方式
本发明的核心之一在于提供一种车把折叠总成，以便提高车把折叠操作便利性，同时能够提升车把折叠操作时的安全性。
本发明的另一核心在于提供一种采用上述车把折叠总成的折叠车。
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做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。
如图1中所示，本发明中所公开的车把折叠总成，包括前盖2、把手5、锁止按钮6、滑动套筒8、复位弹簧7以及后盖9，其中，前盖2用于与车架的龙头支撑臂1相连，并且前盖2的两端对称开设有翻边孔，翻边孔的翻边形成供把手5安装的把手转轴，把手5包括两个，两个把手5对称地安装在上述把手转轴上，如图1至图3中所示，把手5用于与把手转轴配合的一端设置有安装环，安装环可转动地套接在把手转轴上，并且安装环内设置有展开定位槽501和折叠定位槽，展开定位槽501用于在把手5展开式对其进行定位，折叠定位槽用于在把手5折叠时对把手5进行定位。
锁止按钮6穿设在安装环内，如图2和图3中所示，并且锁止按钮6的一 端会伸出翻边孔，锁止按钮6位于安装环内的一端设置有与展开定位槽501和折叠定位槽适配的定位凸起601，滑动套筒8固定设置在后盖9内，滑动套筒8的作用在于供锁止按钮6前后移动，并防止锁止按钮6发生转动，以实现锁止和解锁的动作，后盖9扣合在前盖2上，并与前盖2固定相连，复位弹簧7嵌设在滑动套筒8内，该复位弹簧7的一端与滑动套筒8底部相抵，另一端与锁止按钮6相抵，通过该种设置，可使复位弹簧7将低位凸起压紧在展开定位槽501或折叠定位槽中。
需要进行说明的是，在本发明实施例中，当用户在骑行时，用户直接面对的车把折叠总成一面称为车把折叠总成的前面，与前面相对的另一面为后面，前盖2和后盖9的命名方式也遵循该定义。
请参考图1至图4，本发明所公开的车把折叠总成的操作方法如下：
按住锁止按钮6，锁止按钮6将沿着滑动套筒8向后滑动，锁止按钮6上的定位凸起601将与安装环脱离，此时把手5可以自由转动，当把手5转动至展开位置时，松开锁止按钮6，锁止按钮6上的定位凸起601在复位弹簧7的作用下被压紧于展开定位槽501内实现展开锁止；当把手5转动至折叠位置时，松开锁止按钮6，锁止按钮6上的定位凸起601在复位弹簧7的作用下被压紧于折叠定位槽内实现折叠锁止。
可以看出，上述实施例中所公开的车把折叠总成结构设计和装配过程简单，把手5上的安装环、锁止按钮6以及滑动套筒8均是同轴设计，完成装配后仅仅是锁止按钮6露出前盖2，符合极简设计的要求；另外，展开和锁止过程仅仅通过按压锁止按钮6并转动把手5即可，没有变形的孔隙外露，彻底解决了现有技术中折叠把手5锁紧过程中容易夹手的问题，消除了安全隐患，提升了用户使用体验；同时定位槽与定位凸起601的配合可以保证车把的稳定性，提升用户驾驶信心。
请参考图3，本实施例中安装环的中部被设计为阶梯孔，该阶梯孔靠近滑动套筒8的一侧为大孔，相应的，阶梯孔的另一侧为小孔，展开定位槽501和折叠定位槽开设在与滑动套筒8相对的台阶端面上。当然，本领域技术人员还可将安装环的中部设计为等径的通孔，展开定位槽501和折叠定位槽开设在通孔的侧壁上即可。
不难理解的是，无论是定位凸起601与展开定位槽501配合，还是定位凸起601与折叠定位槽配合，其目的均是防止把手5发生转动，可以实现该目的的定位凸起601只要是非圆形即可，例如三角形、正多边形等，考虑到设计和制造的便利性，本实施例中定位凸起601呈长条状，也就是“一”字型，如图1至图3中所示，相应的，展开定位槽501和折叠定位槽也是与定位凸起601适配的长条状定位槽。
如图1和图2中所示，滑动套筒8的侧壁上设置有导向槽，定位凸起601嵌设在该导向槽内，并可沿导向槽前后滑动，导向槽一方面可以为锁止按钮6进行导向，另一方面还可有效防止锁止按钮6产生转动。
为了进一步优化上述实施例中的技术方案，本实施例中所公开的车把折叠总成中，安装环的外壁上还设置有防止把手5展开时过度旋转的展开限位端面502，和用于防止把手5折叠时过度旋转的折叠限位端面，前盖2上还设置有弧形止推件201，如图1和图2中所示，该弧形止推件201与展开限位端面502和折叠限位端面配合，以防止把手5的过度旋转。
除此之外，申请人还对上述技术方案作出了更进一步的优化，在展开定位槽501和折叠定位槽之间，还设置有调节定位槽，调节定位槽可以设置为多个，相邻两个调节定位槽之间的夹角应当较小，例如5°或10°，调节定位槽可以满足用户将把手5调为不同角度的需求，以提升整车的灵活多变性。通常情况下，把手5展开状态应当是两个把手5的轴线均处于水平状态，把手5折叠状态是两个把手5的轴线均处于竖直状态。
如图1中所示，滑动套筒8与后盖9之间、后盖9与前盖2之间均通过螺钉3紧固连接，螺钉3紧固连接可以方便整个车把折叠总成的拆装和维修，为了进一步提高安装稳固性，把手5的安装环与前盖2之间，以及滑动套筒8与后盖9之间均设置有垫片4。
本发明还公开了一种折叠车，该折叠车包括车把折叠总成，并且车把折叠总成为上述任意一实施例中所公开的车把折叠总成。
需要说明的是，该折叠车包括但不限于自行车、电动车和滑板车，由于该折叠车采用了上述车把折叠总成，因此该折叠车兼具上述车把折叠总成相应的技术优点，本文中对此不再进行赘述。
本说明书中各个实施例采用递进的方式描述，每个实施例重点说明的都是与其他实施例的不同之处，各个实施例之间相同相似部分互相参见即可。
对所公开的实施例的上述说明，使本领域专业技术人员能够实现或使用本发明。对这些实施例的多种修改对本领域的专业技术人员来说将是显而易见的，本文中所定义的一般原理可以在不脱离本发明的精神或范围的情况下，在其它实施例中实现。因此，本发明将不会被限制于本文所示的这些实施例，而是要符合与本文所公开的原理和新颖特点相一致的最宽的范围。
