Description

一种可折叠行李箱 技术领域
本实用新型涉及一种行李箱，尤其是一种可折叠行李箱。
背景技术
行李箱是日常放置物品和出行用品，在用户的长短途出行中起到了很大的作用，但常规的行李箱也存在一定的问题，一般而言符合登机尺寸的行李箱(航空公司登记尺寸要求为高度不超过55厘米、宽度不超过40厘米、厚度不超过20厘米或者长宽高三者之和不超过115厘米，不论是硬箱还是软箱，存在一个最大的载物容积，而且相对是刚性的容量，如果恰好有部分超出刚性容量的物品，就无法妥善收纳在行李箱中；而如果强行收纳额外的物品导致行李箱鼓起而变形，会对箱内物品和行李箱本身造成潜在的损坏，而且在登机安检时就无法通过尺寸检查，需要花费额外的时间办理手续和下飞机后等待接收托运的行李。常规行李箱功能较为单一，除了存放衣物，起到运输行李箱的作用，通常存放于家里、交通工具或酒店里，使用功能和使用场景有局限性。因此，需要设计一种软硬结合的折叠结构，降低行李箱运输的成本和收纳的空间。
发明内容
本实用新型是要提出一种可折叠行李箱，用于降低行李箱运输的成本和收纳的空间。
为实现上述目的，本实用新型的技术方案是：一种可折叠行李箱，由前箱壳、后箱壳、顶箱壳、底箱壳、侧箱壳、角连接片组成，所述前箱壳、后箱壳、顶箱壳、底箱壳、侧箱壳组成行李箱的箱体，所述角连接片分别设置在箱体的左上，右上，左下，右下角，并与顶箱壳，底箱壳，侧箱壳通过缝线连接，构成一个折叠模组，所述折叠模组与前箱壳的前盖通过前拉链连接，与后箱壳的后盖通过后连接条和缝线连接，所述后连接条上通过缝线连接后拉链齿。
进一步，所述顶箱壳的顶面，侧箱壳均呈梯形，所述角连接片展开亦为梯形，能 满足强度和折叠的功能需求。
进一步，所述箱体的箱壳部分为可缝纫的硬质材料，所述硬质材料为ABS、PC或PP。
进一步，所述角连接片与后连接条为容易弯折的软质面料，所述软质面料为尼龙面料、聚酯纤维、超纤、皮革中的任一种。
进一步，所述前箱壳与折叠模组之间的前拉链为可拆卸拉链。
进一步，所述前箱壳通过前拉链的拉链齿与后箱壳上的后拉链齿结合为收纳状态。
一种可折叠行李箱，包括前箱壳和后箱壳，以及展开时呈框形的折叠模组，其中：
所述折叠模组的一侧边缘与后箱壳借助可弯折的后连接条连接；
所述折叠模组的另一侧边缘上设有环绕一周的链齿，后箱壳的外侧连接有环绕一周的后拉链齿；
所述前箱壳上设有环绕一周的链齿以及位于该链齿外侧的副链齿；其中，
前箱壳上的所述链齿及副链齿中的任一者用于与折叠模组上的所述链齿连接，或者，收纳时，前箱壳上的所述链齿及副链齿中的任一者用于与所述后拉链齿连接。
进一步地，所述副链齿相对于前箱壳上的所述链齿向前箱壳的一侧伸出。
本实用新型的有益效果是：
本实用新型采用软硬结合的折叠结构，能降低行李箱运输的成本和收纳的空间。
当需要放置物品或运输物品时，将前盖拆卸，把左右侧箱壳和顶箱壳和底箱壳向外展开，从而使得行李箱的整体容积变大，能够装入更多的物品。
当需要收纳时，将前箱壳拆卸，把左右侧箱壳和顶箱壳和底箱壳向内折叠至后箱壳内部，将前箱壳与后拉链齿通过可拆卸拉链结合为收纳状态。

具体实施方式
下面结合附图与实施例对本实用新型作进一步说明。
如图1至图5所示，一种可折叠行李箱，由前箱壳1、后箱壳2、顶箱壳3、底箱壳9、侧箱壳4、角连接片5组成，其间由缝线连接。前箱壳1、后箱壳2、顶箱壳3、底箱壳9、侧箱壳4组成行李箱的箱体。角连接片分别设置在箱体的左上，右上，左下，右下角，并与顶箱壳3，底箱壳9，侧箱壳4通过缝线连接，构成一个折叠模组。该折叠模组与前箱壳1通过前拉链7连接，与后箱壳2通过后连接条6和缝线连接。后连接条6上通过缝线连接后拉链齿8。
优选的，箱体的箱壳部分为硬质，如ABS，PC，PP等硬质塑胶材质，可缝纫。
优选的，角连接片5与后连接条6为软质面料，如尼龙面料，聚酯纤维，超纤，皮革，等柔性材质，容易弯折。
优选的，前箱壳1与折叠模组之间的前拉链7可拆卸，后连接条6上缝有后拉链齿8，前箱壳1上的前拉链7的拉链齿可与后拉链齿8结合为收纳状态。
优选的，顶箱壳3的顶面，侧箱壳4呈均梯形，角连接片5展开亦为梯形，可保证强度的同时，满足折叠的功能需求。
如图4所示，底箱壳9的左、右两侧各连接一角连接片5，顶箱壳3的左、右两侧也各连接一角连接片5。底箱壳9和顶箱壳3左侧的两角连接片5之间连接一所述侧箱壳4，底箱壳9和顶箱壳3右侧的两角连接片5之间连接另一所述侧箱壳4，构成的所述折叠模组大致呈矩形的框架结构。
角连接片5为梯形，各个角连接片5的较长的底边均位于同一侧，即连接前箱壳1的一侧，以更方便于将底箱壳9、顶箱壳3、侧箱壳4的这一侧边缘向内收叠。
结合图6所示，前拉链7包括两条可咬合在一起的链齿70。前拉链7的一条所述链齿70连接在前箱壳1上，并且环绕前箱壳1的边缘一周。所述折叠模组的一侧边缘与后连接条6连接，所述折叠模组的另一侧边缘上则连接有前拉链7的另一条所述链齿70，并且链齿环绕折叠模组的边缘一周。借助前拉链7，可打开或者关闭前箱 壳1，也可以取下前箱壳1。
如图4至图5所示，折叠过程：拆卸掉前盖，左右侧箱壳4向内折叠至后箱壳2内部，再将顶箱壳3和底箱壳9向内折叠至后箱壳2内部。或先将顶箱壳3和底箱壳9向内折叠至后箱壳2内部，再将左右侧箱壳4向内折叠至后箱壳2内部。最后，将前盖与后拉链齿8通过可拆卸拉链结合为收纳状态。展开过程为反向操作。
如图7所示，前拉链7的连接于前箱壳1上的所述链齿70与后拉链齿8连接，将前箱壳1与后箱壳2固定在一起，折叠模组则容纳于前箱壳1与后箱壳2内。
如图8所示，本实施例中，前箱壳1上还设置有一条副链齿71，其相对地位于前拉链7设置在前箱壳1上的所述链齿70的外侧。如此设置，前箱壳1上设有两条链齿，即设置在前箱壳1上的所述链齿70以及所述副链齿71。
收纳时，所述副链齿71与所述后拉链齿8相互咬合连接，将前箱壳1与后箱壳2固定在一起。
前箱壳1上的所述链齿70上设有一拉片72，所述副链齿71上则设有另一拉片72，两个拉片72独立使用，更加方便。
