具体实施方式
下面结合附图及实施例对本发明作进一步描述：
实施例一
如图1所示的一种旅行床，具有展开状态和折叠状态，包括底支架、上围框、设置在底支架和上围框之间的4个立杆1、分别设置在4个立杆1下端部的固定座20。以下具体对各个部件做详细介绍：
底支架包括：4根底杆40、与多根底杆40一端部相转动连接的连接座，连接座包括上底盘41、沿上下方向能够滑动设置在上底盘41内的下底盘42以及连接杆43，底杆40的一端部与上底盘41通过轴c相转动连接，连接杆43的一端部与底杆40通过轴b相转动连接，另一端部与下底盘42通过轴a相转动连接。
固定座20上设置有轮子21。
上围框包括：端部分别通过轴d1和d2、轴d3和d4与第一连接件32相转动连接的第一围杆和第二围杆，第一围杆包括一端部通过轴e1和e2、e3和e4与第二连接件330相转动连接的第一连杆30和第二连杆31，第一连杆30包括上下平行设置的第一上杆300、第一下杆301，第二连杆31包括上下平行设置第二上杆310、第二下杆311；第二围杆包括一端部通过轴e5和e6、e7和e8与第三连接件340相转动连接的第三连杆35和第四连杆36，第三连杆35包括上下平行设置的第三上杆350、第三下杆351，第四连杆36包括上下平行设置第四上杆360、第四下杆361。
如附图2-3所示：旅行床沿立杆1 的延伸方向延伸的顶杆50、用于将顶杆50 分别与第一围杆和第二围杆相连接的顶杆撑杆6，其中：立杆1 的上端部固定连接在第一连接件32 上，立杆1 上设置有顶杆固定套51，顶杆50 设置在顶杆固定套51 内。顶杆50 上端部分别转动连接有两个顶杆撑杆6，两个顶杆撑杆6 分别通过轴g1 和g2、轴g3 和g4 与连接在同一个第一连接件32 上的第一围杆和第二围杆相转动连接，具体为第一下杆301 和第三下杆351、第二下杆311 和第四下杆361。
旅行床还包括设置在各固定座20上的凸轮组件，凸轮组件包括与顶杆50底部相固定连接的顶杆凸出部501、固定连接在底杆40另一端部并与固定座20通过轴f相转动连接的底杆凹陷部401，顶杆凸出部501收容在底杆凹陷部401内。
旅行床折叠时，第一下杆301、第二下杆311、第三下杆351、第四下杆361 的转动，使得顶杆50 被向下压，使顶杆凸出部501 向下压底杆凹陷部401，从而使得底杆40 与连接座连接的一端以底杆凹陷部401 为轴向上转动，以此实现立杆1 以大致竖直的状态且相互平行向中部靠拢收折。
如图4-5所示：上围框还包括分别将第一连杆30、第二连杆31中的第一上杆300、第二上杆310与第二连接件330相锁定的第一锁定单元和用于使第一锁定单元解锁的第一解锁单元，分别将第三连杆35、第四连杆36中的第三上杆350、第四上杆360与第三连接件340相锁定的第二锁定单元和用于使第二锁定单元解锁的第二解锁单元，第一解锁单元和第二解锁单元之间通过牵引索37联动，当第一解锁单元和第二解锁单元中的一个进行解锁操作时，第一锁定单元和第二锁定单元同时解锁。
参见图4所示，第一锁定单元包括一端部与第二连接件330相转动连接的第一摆块331、分别固定在第一连杆30和第二连杆31的一端部且与第二连接件330相转动连接的第一锁块332，本实施例中的第一锁块332与第二连接件330转轴分别为上述的轴e1和e3。当第一锁定单元处于锁定状态时，第一摆块331与第一锁块332相抵，使第一锁块332不能向下转动，亦即第一连杆30和第二连杆31不能相对第二连接件330转动；当第一锁定单元解锁时，第一摆块331与第一锁块332分离，第一连杆30和第二连杆31可分别绕各自与第二连接件330的转动连接轴转动，第一连杆30和第二连杆31可折叠。本实施例中，第一摆块331和第一锁块332有两组，两组第一摆块331和第一锁块332分别对称设于第二连接件330上。
第一解锁单元包括能够上下滑动地设于第二连接件330上的解锁捏手338、设置在解锁捏手338的相对两侧并沿上下方向延伸的第一滑槽335、设置在第二连接件330的相对两侧并沿水平方向延伸的第二滑槽333、设置在第一摆块331的另一端部的第一销钉800，第一滑槽335包括沿上下方向延伸的斜槽335a，第一销钉800能够沿第一滑槽335和第二滑槽333滑动地穿过第一滑槽335和第二滑槽333。当解锁捏手338滑动时，驱使第一销钉800在第一滑槽335和第二滑槽333中滑动，并驱使第一摆块331转动与第一锁块332相抵或分离。本实施例中，当第一锁定单元锁定时，第一销钉800位于第二滑槽333的外端、第一滑槽335的上端；当第一锁定单元解锁时，第一销钉800位于第二滑槽333的内端、第一滑槽335的下端，向上推动解锁捏手338，使得第一摆块331转动与第一锁块332分离，第一锁定单元便处于解锁状态。第一锁定单元还包括驱使第一摆块331从解锁状态向锁定状态复位的第一弹性件334，本实施例中，第一弹性件334采用弹簧，弹簧的两端分别与第二连接件330和第一销钉800连接。
参见图5所示，第二锁定单元包括分别固定在第四连杆36和第三连杆35的一端部且与第三连接件340相转动连接的第二锁块342、一端部与第二锁块342相转动连接的第二摆块341、与第二摆块341的另一端部相转动连接的连接块344，连接块344与第三连接件340相转动连接，第三连接件340、第二锁块342、第二摆块341、连接块344之间构成一个四连杆机构，当该四连杆机构处于死点位置时，第二锁定单元便处于锁定状态。本实施例中，四连杆机构有两组，两组四连杆机构在第三连接件340上对称设置。
具体的，本实施例中，第二摆块341与连接块344通过第三销钉802相转动连接，连接块344与第三连接件340通过第四销钉803相转动连接，第三连接件340与第二锁块342通过第五销钉804（本实施例中，第五销钉804即为轴e5、e7）相转动连接，第二锁块342与第二摆块341通过第六销钉805相转动连接，第四销钉803和第六销钉805的中心连线形成一直线，当第三销钉802的中心也位于该直线上，或者第三销钉802和第五销钉804的中心分别位于该直线的两侧时，该四连杆机构处于死点位置，当第三销钉802的中心向第五销钉804的中心所在一侧移动并越过上述的直线位置时，该四连杆机构过死点，第二锁定单元便处于解锁状态。
参见图4-5所示，解锁捏手338上设置有能够上下滑动的第二连接件330、能够转动地的第一驱动件336。第二解锁单元包括能够上下滑动地设置在第三连接件340上的第二驱动件346，第一驱动件336上固定连接有上述牵引索37的一端部，第二驱动件346上固定连接有上述牵引索37的另一端部，牵引索37设置在第四连杆36、第三连杆35、第一连杆30和第二连杆31中的管腔中，使得该围框外型整洁美观。本实施例中，上述的两组四连杆机构对称设于第二驱动件346的相对的两侧。
进一步地，解锁捏手338上设有第二销钉801，第二销钉801与第一驱动件336相配合，第二摆块341与第二驱动件346相配合，第三连接件340的相对两侧设有第三滑槽343，第三滑槽343为弧槽，沿上下方向延伸，第三销钉802穿过第三滑槽343且能够沿第三滑槽343滑动，本实施例中，当第二锁定单元处于锁定状态时，第三销钉802在第三滑槽343的上端，当第二锁定单元处于解锁状态时，第三销钉802在第三滑槽343的下端。当第二锁定单元解锁时，向上推动解锁捏手338，解锁捏手338向上滑动的过程中，通过第二销钉801与第一驱动件336的配合驱使第一驱动件336转动，第一驱动件336转动便将牵引索37拉紧，牵引索37拉动第二驱动件346向上滑动，通过第二驱动件346与第二摆块341的配合，驱使第二摆块341摆动，从而使得第三销钉802在第三滑槽343内从上向下且向第五销钉804一侧滑动，直至第三销钉802的中心滑动到越过第四销钉803和第六销钉805中心所在直线，即第三连接件340、第二锁块342、第二摆块341、连接块344之间构成的四连杆机构过死点，第二锁定单元便解锁，第四连杆36和第三连杆35便可转动折叠。
为降低解锁时对解锁捏手338的操作力，解锁时，使第二锁定单元和第一锁定单元顺次解锁，具体方式为：第一滑槽335还包括沿上下方向延伸的直槽335b，直槽335b与斜槽335a相连通，直槽335b在第一滑槽335内位于解锁捏手338解锁时第一销钉800滑动方向的起始端。本实施例中，直槽335b位于斜槽335a的上端。解锁时，向上推动解锁捏手338，解锁捏手338滑动时，第一销钉800在直槽335b中滑动，此时，第一摆块331保持不动，第一锁定单元处于锁定状态，随解锁捏手338向上滑动，第二销钉801与第一驱动件336相抵驱使第一驱动件336转动，第一驱动件336转动便将牵引索37拉紧，牵引索37拉动第二驱动件346向上滑动，第二驱动件346与第二摆块341配合驱使第二摆块341摆动，使第三销钉802在第三滑槽343内滑动，使第三连接件340、第二锁块342、第二摆块341、连接块344之间构成的四连杆机构过死点，第二锁定单元解锁，当解锁捏手338向上滑动使第一销钉800从直槽335b中滑动到斜槽335a中后，此时解锁捏手338继续上滑，驱使第一摆块331转动与第一锁块332分离，第一锁定单元便解锁。
该围框还包括分别驱使解锁捏手338和第二驱动件346从解锁状态向锁定状态复位的第二弹性件337和第三弹性件345，第二弹性件337和第三弹性件345均采用弹簧，第二弹性件337的两端分别与解锁捏手338和第二连接件330连接，第三弹性件345的两端分别与第二驱动件346和第三连接件340连接。
本旅行床的展开和折叠过程：
旅行床在展开状态时：第一连杆30、第二连杆31、第三连杆35、第四连杆36相互之间均处于相对展开状态，第一锁定单元、第二锁定单元均锁定。
旅行床需要进行折叠时：操作解锁捏手338相对第二连接件330向上滑动，并向下压第二连接件330，在牵引索37的作用下，第一解锁单元和第二解锁单元中各部件同时按照上文所述动作使第一锁定单元和第二锁定单元中各部件动作并同时解锁，第一连杆30（第一上杆300和第一下杆301）、第二连杆31（第二上杆310和第二下杆311）转动并相互靠拢，第三连杆35（第三上杆350和第三下杆351）、第四连杆36（第四上杆360和第四下杆361）转动并相互靠拢，根据上文所述，第一下杆301、第二下杆311、第三下杆351、第四下杆361的转动使得顶杆50下压，在凸轮组件的作用下，立杆1相中部靠拢收折，从而最终完成旅行床的折叠，并使旅行装保持折叠状态。
旅行床需要进行展开时：下压连接座，使底杆40 处于展开状态，同时带动围框展开，使第一锁定单元、第二锁定单元锁定即可。或者同时拎第二连接件330 或第三连接件340使床架展开，使第一锁定单元、第二锁定单元锁定即可，在此展开过程中无需操作解锁捏手338。
实施例二
如图8-13所示：本实施例中的旅行床与实施例一的区别仅在于：顶杆50能够沿立杆1长度方向滑动，并且旅行床还包括套设在顶杆50外部的弹簧7，其中：顶杆50的下部插设在顶杆固定套51内，顶杆50的上部固定有角形的上连接块52，顶杆撑杆6转动连接在上连接块52上，弹簧7的上端部抵住上连接块52，下端部抵在顶杆固定套51的上端部。
旅行床折叠时，第一连杆30（第一上杆300和第一下杆301）、第二连杆31（第二上杆310和第二下杆311）转动并相互靠拢，第三连杆35（第三上杆350和第三下杆351）、第四连杆36（第四上杆360和第四下杆361）转动并相互靠拢，第一下杆301、第二下杆311、第三下杆351、第四下杆361在转动过程中，使得顶杆50被向下压同时顶杆撑杆6向下压缩弹簧7，顶杆凸出部501向下压底杆凹陷部401，从而使得底杆40与连接座连接的一端以底杆凹陷部401为轴向上转动，以此实现立杆1以大致竖直的状态且相互平行向中部靠拢收折，弹簧7处于压缩状态，如图7、8所示，此时由于顶杆撑杆6与顶杆50相靠近并接近平行，相当于顶杆撑杆6竖直向下压弹簧7，克服了弹簧7弹性力而对顶杆撑杆6产生的转动趋势，使旅行床保持折叠状态。当旅行床在折叠状态时向外拉动第一连接件32，使顶杆撑杆6倾斜，处于压缩状态的弹簧7释放弹性力上部顶顶杆撑杆6，顶杆撑杆6转动并推动第一下杆301、第二下杆311、第三下杆351、第四下杆361的转动，使上围框在弹性力的作用下实现自动打开。
上述实施例只为说明本实用新型的技术构思及特点，其目的在于让熟悉此项技术的人士能够了解本实用新型的内容并据以实施，并不能以此限制本实用新型的保护范围。凡根据本实用新型精神实质所作的等效变化或修饰，都应涵盖在本实用新型的保护范围之内。
