具体实施方式
下面将结合本申请实施例中的附图，对本申请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申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，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，都属于本申请保护的范围。
本申请的核心是提供一种折叠装置，结构设置较为简单。
请参考图1至图6，图1为本申请所提供折叠装置的具体实施例的爆炸图；图2为本申请所提供折叠装置的具体实施例在展开状态下的结构示意图；图3为本申请所提供折叠装置的具体实施例在折叠状态下的结构示意图；图4为本申请所提供折叠装置的具体实施例在展开状态下的剖视图；图5为本申请所提供折叠装置的具体实施例在解锁状态下的剖视图；图6为本申请所提供折叠装置的具体实施例在折叠状态下的剖视图。
本申请所提供折叠装置的一种具体实施例中，包括连接管1、挂钩4、支撑件、用于对连接管1的展开限位的限位件和复位件8，连接管1铰接于支撑件。其中，挂钩4包括：锁定部402、按压部401连接部403和固定部404。锁定部402用于在连接管1折叠至设定位置时与连接管1中的配合件相配合锁定，锁定部402设置在连接管1的内部；按压部401用于解锁，按压部401设置在连接管1外侧，限位件与按压部401分别设置在连接管1的两侧，复位件8向锁定部402施加朝向按压部401的力，使锁定部402具有靠向按压部401的方向运动的趋势；连接部403用于连接锁定部402与按压部401，同时，连接部403铰接于支撑件，从而使挂钩4连接于支撑件，通常，挂钩4的转动方向与连接管1的转动方向相同；固定部404可以在连接管1展开至限位件时固定连接管1，即固定部404与限位件配合固定连接管1的展开。
在展开连接管1时，按动按压部401，使锁定部402与配合件之间解锁，连接管1旋转至限位件处停止转动，同时，固定部404与连接管1配合固定；在折叠连接管1时，按动按压部401并反方向转动连接管1，使锁定部402与连接管1在旋转至设定位置时相配合锁定。其中，展开连接管1指的是连接管1两侧的把手与车体7相远离，折叠指的是把手与车体7相靠近。
此种折叠装置的挂钩4中，按压部401、固定部404与锁定部402呈一体设置，整体结构更加简单，使用时能够保证按压部401、固定部404与锁定部402转动的同步性，控制可靠，且在装配于支撑件时，只需完成连接部403与支撑件的铰接即可，装配工序较少，装配成本较低，同时，由于锁定部402与按压部401分别设置在连接管1的内外两侧，连接部403以及锁定部402上、按压部401上靠近连接部403处能够遮挡与连接管1的对卡位置，可以防止此处卡住手或者其他异物，具有一定的保护作用。
上述实施例中，挂钩4具体可以为V字形挂钩，其中，设于V字形挂钩的顶角处的即为连接部403，固定部404与锁定部设置在挂钩4的一端，且固定部404为与连接管1伸入挂钩4中的端部卡接配合的台阶，按压部401设置在挂钩4的另一端。此种挂钩4结构简单，有利于节约挂钩4的占用空间，同时，充分利用连接管1与挂钩4之间的位置关系进行连接管1展开时的固定，限位可靠。当然，挂钩4也可以为X形挂钩或者其他形状。
上述各个实施例中，连接管1可以通过车体折叠轴3铰接于支撑件，连接部403可以通过挂钩折叠轴9铰接于支撑件，挂钩折叠轴9与车体折叠轴3相平行。也就是说，连接管1与挂钩4通过分别不同的轴实现与支撑件的铰接，便于安装，且有利于防止连接管1与挂钩4之间运动的干涉。当然，连接管1与挂钩4也可以铰接于同一轴件。
上述各个实施例中，锁定部402的自由端设有朝向按压部401开口的锁定槽，锁定部402的自由端指的是锁定部402上远离连接部403的一端；配合件为用于与锁定槽配合的第一限位柱10，第一限位柱10设置在挂钩4折叠时的转动轨迹上，以便连接管1转动至设定位置时锁定槽钩住第一限位柱10，此种设置方式便于锁定槽在锁定部402上的定位与加工。当然，锁定槽也可以设置在锁定部402的中部或者其他位置。
具体地，第一限位柱10可以转动连接于连接管1上且位于连接管1的内部，从而减小锁定槽与第一限位柱10之间的摩擦，延长第一限位柱10的使用寿命。又或者，第一限位柱10可以固定连接于连接管1，具体可以为螺纹连接、焊接或者其他方式连接，锁定时稳定性较好。当然，配合件的设置方式不限于此，例如，配合件也可以为凸出于连接管1内壁的柱形凸起，且该柱形凸起设置在挂钩4折叠时的转动轨迹上。
上述各个实施例中，复位件8可以为设置于车体折叠轴3的人字簧，人字簧的开口方向与挂钩4的开口方向相同，以便减轻人字簧的变形程度，延长复位件8的使用寿命，将人字簧设置在车体折叠轴3上，且人字簧设于连接管1的内部，可以减少折叠装置中的零件设置。当然，复位件8也可以为压缩弹簧、电磁铁或者其他复位件8。
上述各个实施例中，支撑件具体可以包括设于连接管1的两侧的两个支撑 板5，一个支撑板5的一侧还设有用于夹紧支撑板5与连接管1的锁紧扳手组件6，设置方便，且能够保证夹紧连接管1和支撑板5，消除连接管1与支撑板5之间的间隙，使连接管1得到稳定支撑。当然，支撑件的设置方式不限于此。
具体地，锁紧扳手组件6中连接支撑板5处的表面可以设置弹性耐磨层，例如聚酯胺层，在消除间隙的同时保证锁紧扳手组件6的使用寿命较长。
上述各个实施例中，限位件可以为可拆卸连接于两个支撑板5之间的第二限位柱2，便于安装与维修。当然，限位件也可以为设于支撑件一侧的单独的限位装置，或者进行其他设置。
具体地，支撑板5上连接第二限位柱2的孔可以为槽型孔，第二限位柱2通过紧钉螺钉锁紧，则在第二限位柱2使用一段时间发生了磨损时，可以通过调节机构微调紧钉螺钉以消除间隙。
上述各个实施例中，按压部401的轴向长度与连接管1的轴向长度的比值范围可以为0.5至1，轴向指的是连接管1与支撑件之间铰接轴的指向，以保证按压部401对连接管1具有较大的覆盖面积，按压操作较为舒适。具体地，按压部401可以设置在连接管1的轴向的中部。当然，按压部401相对于连接管1的尺寸以及位置关系的设置不限于此。
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。
以上对本申请所提供的折叠装置进行了详细介绍。本文中应用了具体个例对本申请的原理及实施方式进行了阐述，以上实施例的说明只是用于帮助理解本申请的方法及其核心思想。应当指出，对于本技术领域的普通技术人员来说，在不脱离本申请原理的前提下，还可以对本申请进行若干改进和修饰，这些改进和修饰也落入本申请权利要求的保护范围内。
