Description

一种具有可折叠转换使用形态的车辆 技术领域
本发明涉及车辆技术领域，特别涉及一种具有可折叠转换使用形态的车辆。
背景技术
目前市场上流行的折叠式自行车的种类比较多，折叠方式也有很多种，它们折叠的共同目的是缩小自行车的体积、方便于携带和收藏保管。由于这类折叠式自行车虽然在折叠状态下有效地缩小了体积，但大多丧失了在地面上正常骑乘或推动的功能，特别是在某些不适合骑行、但需要步行较长距离的场合，虽然可以折叠后在缩小了体积的情况下携带，但还是需要使用者用手提或肩扛的方式携带，既费力又不太方便，有时甚至成为出行的累赘。现在的折叠自行车的作用局限于改变外形尺寸，缩小占位空间存放和便于携带。
如公告号CN207631413U，公开了一种结构简单、折叠效率高、通过性好的自行车折叠机构，其包括：一个可伸缩的前支架组件，一个可伸缩的主支架组件，一个头管组件，一个鞍座组件及一个后轮组件；所述头管组件的一端与所述前支架组件以轴旋式连接，而另一端与所述主支架组件以轴旋式连接；所述鞍座组件带有一个与所述主支架组件以旋轴式连接的座管；所述后轮组件带有一个与所述主支架以旋轴式连接的后轮叉及设置于所述后轮叉与所述座管之间分别以旋轴式连接的后轮叉连杆。
如公告号为CN213620094U，一种折叠式自行车，包括车架，连接于车架的座管与首管，车架包括立管，头管，以及连接于立管与头管之间的横梁，横梁的前端与后端均可折叠，且横梁的前端的折叠方向与横梁后端的折叠方向相反；首管下侧可竖向折叠。本申请实施例提供的折叠式自行车，能够在横梁前端位置折叠，使得车头处被朝向车身一侧折叠，还能够在横梁后端位置折叠，使得自行车被从中部折叠，并且首管可以朝向下侧折叠，使得车把被折叠后位于自行车前轮的一侧。
然而，现有的大部分折叠自行车通常均是采用小轮径规格，其车轮尺寸规格通常为20、16英寸甚至更小尺寸，导致其骑行时通过性较弱，舒适感相对较差，且车速相对较慢。现有采用大轮径的自行车，其轮径尺寸通常为26英寸或更大，而该类自行车通常是无法实现良好的折叠效果，通常是需要将前轮或后轮进行快速拆卸后实现体积缩小，拆卸折叠后失去利用车轮移动的功能，需要使用者自行抬运，费力费事，个别具有折叠结构的自行车其折叠后体积依旧较大，紧凑性不足，影响使用效果；同时，对于现有小轮径规格尺寸的折叠自行车，其通常采用的是单一主梁双杠折叠结构，导致其整体车梁稳定性相对较差。

本实施例中，纵梁326长度尺寸缩短，同时保留加强车梁220和折叠车梁210的长度规格尺寸，利用结构优化，可以适用于小轮径规格的折叠自行车使用，该结构拆卸折叠操作方便。
在整体结构中，第一横梁324和第一车梁211分别与后车部300和前车部100优选采用固定结构，通常为焊接固定为一体，第一横梁324和第一车梁211之间设置第二车梁212，第二车梁212两端分别与第一横梁324和第一车梁211铰接配合，可以实现水平方向折叠设置；第二横梁325和加强固定梁223分别与后车部300和前车部100优选采用固定结构，通常为焊接固定为一体，第二横梁325和加强固定梁223之间设有加强移动梁224，其中，加强移动梁224与加强固定梁223之间优选采用铰接结构，另一端与叠合的第一横梁324采用可拆卸固定结构，在其余实施例中，也可以采用与第二横梁325端部采用可拆卸固定结构代替。
当车辆展开时，第一横梁324、第二车梁212、第一车梁211整体形成一个上车梁结构，第二横梁325、加强移动梁224和加强固定梁223形成一个下车梁结构，上下车梁还通过固定件可以实现对接固定，从而形成一个整体车梁结构，具有良好的稳定性。
当车辆折叠时，加强移动梁224完成与第一横梁324或第二横梁325的拆卸分离，将加强移动梁224通过与加强固定梁223的铰接配合，转动至其他位置；上车梁中的第一横梁324、第二车梁212和第一车梁211依据实施例1中对应折叠结构，实现“凵”形结构折叠，使得前车部100和后车部300实现车轮并行。
在其中一个优选实施例中，结合附图15和图16所示，第二车梁212可以采用伸缩杆结构设计，优选为双杆伸缩结构，因第二车梁212在整体骑乘过程中受力干扰相对较小，为此，为了折叠形成推车结构后具有更好的推车空间，优选将第二车梁212设置为可伸缩结构，通过伸展后形成具有较大空间的推车，提高产品使用效果。
实施例4
基于上述实施例，结合附图19至图28所示，折叠车梁210中的第二车梁212包括两个第二车梁单元2121，两个第二车梁单元2121相邻处呈铰接配合；当自行车完全折叠时，第一车梁211、两个第二车梁单元2121和后车部300中的横梁部328折叠形成并排设置；其中，结合图22和图23所示，折叠车梁完成折叠时，第一车梁211、两个第二车梁单元2121和后车部300中的横梁部328相互呈平行状态，形成最小收缩结构，在其余结构中，结合图24所示，也可以形成类似“M”形折叠结构；结合图21所示，该结构中，第二车梁212中的两个第二车梁单元2121处于不折叠状态，呈相互对接，第一车梁211相对其中一个第二车梁单元2121相互折叠，后车部300中的横梁部328与另一个第二车梁单元2121相互折叠，形成推车状态结构。
实施例5
结合上述任一实施例，结合图19和图20，其中，加强车梁220和折叠车梁210呈上下排布。
实施例6
结合上述任一实施例，结合图25至图28所示，其中，加强车梁220和折叠车梁210呈左右排布；采用大小不同管径结构设计，可以进行适用于不同规格款式的车型。
实施例7
结合上述任一实施例，结合图26所示，其中，加强车梁220上设有折叠车梁槽201，折叠车梁槽201用以容纳折叠车梁210；采用大小不同管径结构设计，利用嵌装结构排布，可以实现更小规格尺寸，适用于不同规格款式的车型。
在其它结构中，车把部110、车管部120、后车主梁323等结构可以优选采用伸缩结构， 其中车把部110可以采用折叠结构等设计。
本实施例中采用的铰接结构均采用与实施例1中对应的铰接结构，优选采用可限位锁固的铰链结构。
本实施例相对实施例1增加了固定连接环节，增加了车辆整体刚度和稳定性，减少了多个活动机构，降低了折叠展开的操作繁琐程度，简化了机构配件，简化了制造组装工序，也降低了成本，特别适用于小轮径规格的折叠自行车使用。
上述任一结构，其可以适用于自行车、助力车、电动自行车、电动车等车辆中应用，且并不局限于上述车辆。
以上所述，仅是本发明的较佳实施方式，并非对发明作任何形式上的限制，凡是依据本发明的技术原理对以上实施例所做的任何简单修改、等同变化或修饰，仍属于本发明技术方案的范围内。
