一种可上下楼梯的爬梯式拉杆箱
本申请要求于2016年5月31日提交中国专利局、申请号为201610377834.3、发明名称为“一种可上下楼梯的爬梯式拉杆箱”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
本发明公开涉及拉杆箱领域，尤其涉及一种可上下楼梯的爬梯式拉杆箱。
背景技术
拉杆箱是人们外出旅行盛装物品的工具，人们在外出旅行时，为了应对旅途中的各种突发状况，通常会在拉杆箱内装上各种各样的物品。
目前，大多的拉杆箱在下方均设置有滚轮，在拉杆箱的一侧设置有拉杆架，在拉杆件内安装有伸缩拉杆。使用时，人们可以通过拖拽拉杆箱上的伸缩拉杆，通过滚轮的滚动，实现拉杆箱的移动，但是该种移动方式仅仅适用于平坦的路面，一旦遇到台阶或者楼梯时，必须人力将整个拉杆箱提起，然后再进行台阶/楼梯的攀爬。如果需要攀爬的台阶/楼梯个数较少，人们尚可承受，但如果需要攀爬的台阶/楼梯个数较多，例如：攀爬6层楼的楼梯，人们就不得不充当力工，手提/肩抗着沉重的拉杆箱，进行楼梯的攀爬，给人们带来众多不便，同理在下台阶时也存在同样的问题。
因此，如何解决携带拉杆箱时，上下台阶/楼梯困难的问题，成为人们亟待解决的问题。
发明内容
为克服现有技术中，携带拉杆箱上下台阶/楼梯困难的问题，本发明公开提供了一种可上下楼梯的爬梯式拉杆箱。

所述滑板3靠近所述箱体1的一侧侧面上还设置有纵向滑道32，且所述滑板3的侧壁上设置有与所述滑道32连通的通孔；
所述折叠锁定装置5包括：定位销51、折叠压板52以及拉簧53；
所述折叠压板52滑动安装于所述纵向滑道32中，当所述滑板3相对所述箱体1展开时，所述折叠压板52的端部与所述缓冲支杆4相抵；
所述拉簧53一端与所述滑板3固定连接，另一端与所述折叠压板52固定连接；
所述定位销51穿过所述滑板3侧壁上的通孔，与所述折叠压板52一体连接；
所述第一横向支架113上设置有与所述定位销51配合的凹槽1131，当所述滑板3相对于所述箱体1折叠时，所述定位销51恰好卡设于所述凹槽1131内，且在所述凹槽1131上还设置有用于控制所述定位销51下移的控制开关1132。
进一步优选，所述控制开关1132为电磁阀或一端位于所述凹槽1131内，且可相对所述凹槽1131相对移动的活动按钮1132。
进一步优选，所述滑板3的宽度小于等于所述第一拉杆架111与所述第二拉杆架112之间的距离。
进一步优选，所述滑板3远离所述箱体1的一侧侧面上设置有耐磨板33。
进一步优选，所述滑板3的纵向截面呈直线形。
进一步优选，所述滑板3的纵向截面呈类L形，所述滑板3包括：呈钝角连接的滑板主体34以及连接板35，且在所述滑板主体34与所述连接板35的连接处安装有固定脚轮6。
进一步优选，在所述箱体1的底部设置有凹陷区域13，当所述滑板3相对所述箱体1折叠时，所述固定脚轮6恰好容纳于所述凹陷区域13中。
进一步优选，所述滑板3与所述箱体1铰接处固定安装有用于驱动所述滑板3移动的步进电机，在所述扭转弹簧41上固定安装有用于驱动所述缓冲支杆2移动的步进电机。
本发明提供的可上下楼梯的爬梯式拉杆箱，通过在传统的拉杆箱上增设了砥柱、滑板以及缓冲支杆，实现了拉杆箱的爬梯功能，具体为：当需要进行爬梯时，只需将滑板相对箱体展开，并将拉杆箱整体斜向放置，使滑板远离箱体的一侧侧面与台阶的外沿凸角相接，此时，通过伸缩拉杆向上拖拽拉杆箱，滑板与箱体一起沿着台阶的外沿凸角向上移动，由于砥柱和缓冲支杆对滑板的支撑，滑板相对箱体的角度基本保持在一定范围内，当滑板在向上移动的过程中，每当滑板的下缘与一个台阶的外沿凸角脱离时，滑板的上缘便会与另一个台阶的外沿凸角相接，直至爬梯结束，因此，在拖拽拉杆箱爬梯时，犹如拖拽拉杆箱在斜置的平面上行走，将台阶的阶梯性上升过程通过滑板转化为连续线性上升的过程，再也无需人力将整个拉杆箱提起，有效解决了爬梯难的问题。此外，在爬梯的过程中，滑板以一定的倾斜角度接触台阶的外沿凸角，当滑板受到外沿凸角的支撑力后，由于缓冲支杆的作用，滑板会向支撑力的反方向移动，带动缓冲支杆的端部沿着纵向导槽向上运动，使缓冲支杆抵消部分滑板与台阶外沿凸角间的作用力，减小爬梯时对箱体的冲击，使拉杆箱平稳、轻松、顺利地爬梯。同样道理，下楼梯台阶时将拉杆箱前置，沿着台阶轻推拉杆箱，拉杆箱的滑板沿着台阶的外沿凸角向下滑动，顺利的完成下楼梯台阶的目的。
本发明提供的可上下楼梯的爬梯式拉杆箱结构，可适用于拉杆旅行包、拉杆音响、拉杆工具箱、学生拉杆书包、拉杆背包、新型智能拉杆旅行箱包、行李车、婴儿车以及购物车等。

具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述 涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本发明相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本发明的一些方面相一致的装置的例子。
为了解决现有的拉杆箱存在爬梯难等问题，本实施例提供了一种可上下楼梯的爬梯式拉杆箱，参见图1，该拉杆箱包括：箱体1，在箱体1的一侧固定安装有拉杆架11，在拉杆架11内分别安装有2个伸缩拉杆12，在2个伸缩拉杆12的端部之间连接有把手14，在箱体1的底部安装有滚轮15，且该滚轮15为固定滚轮，参见图2，拉杆架11包括纵向平行设置的第一拉杆架111和第二拉杆架112以及两端分别与第一拉杆架111和第二拉杆架112连接的第一横向支架113和第二横向支架114，为了提高拉杆架的牢固程度，在第一拉杆架111和第二拉杆架112之间还设置有支撑架115，在第一拉杆架111和第二拉杆架112之间设置有砥柱2，且该砥柱2的两端分别与第一横向支架113和第二横向支架114固定连接，参见图3，在箱体1的底部，即滚轮15的转轴处铰接有滑板3，该滑板3位于第一拉杆架111和第二拉杆架112之间，其纵向截面为直线形，且当该滑板3相对箱体1展开时，优选，滑板3与滚轮15的外缘相切或接近相切，从而避免在上下台阶时发生颠簸，而当滑板3相对箱体1折叠时，滑板3恰好容纳于由第一拉杆架111、第二拉杆架112以及第一横向支架113围成的区域内，即滑板3的宽度小于等于第一拉杆架111与第二拉杆架112之间的距离，同时在滑板3靠近箱体1的一侧侧面上设置有纵向导槽31，滑板3与砥柱2之间通过缓冲支杆4连接，其中，缓冲支杆4一端滑动安装于纵向导槽31内，另一端通过扭转弹簧41与砥柱2铰接。
使用上述拉杆箱进行爬梯时，首先需要将滑板相对箱体展开，然后将箱体整体斜向放置，使滑板与台阶的外沿凸角相接，当手握把手沿着台阶拖拽拉杆时，滑板在砥柱和缓冲支杆的支撑下会始终保持与台阶外沿凸角相接，由于滑板展开时与滚轮的外缘相切，因此，在爬梯拖拽拉杆箱时，要么滚轮位于两个台阶之间，处于悬空状态，要么滚轮的外缘与台阶的外沿凸角相接与滑板处于同一平面，进而将拉杆箱爬梯过程中的阶梯式上升转化为连续的线性上升，再也无需人力将整个拉杆箱提起，只需沿着滑板所在平面拖拽拉杆箱即可，简化了爬梯的过程，实现了拉杆箱的爬梯功能。此外，在爬梯的过程中，滑板以一定的倾斜角度接触台阶的外沿凸角，当滑板受到外沿凸角的支撑力后，由于缓冲支杆的作用，滑板会 向支撑力的反方向移动，带动缓冲支杆的端部沿着纵向导槽向上运动，使缓冲支杆抵消部分滑板与台阶外沿凸角间的作用力，减小爬梯时对箱体的冲击，使拉杆箱平稳、轻松、顺利地爬梯。同样道理，使用上述拉杆箱下楼梯台阶时将拉杆箱前置，沿楼梯推拉杆箱，箱包滚轮接触到台阶外沿凸角的同时，滑板也接触到台阶外沿凸角，滑板在拉杆箱自重力的作用下向下滑动，这样，拉杆箱随滑板的向下滑动，也平稳的向下移动，达到顺利下楼梯的目的。
为了方便滑板3相对箱体1折叠后的位置固定，方便拉杆箱的携带，作为技术方案的改进，该拉杆箱还包括折叠锁定装置5，参见图5，在滑板3靠近箱体1的一侧侧面上还设置有纵向滑道32，且滑板3的侧壁上设置有与滑道32连通的通孔，参见图3、图4、图6，该折叠锁定装置5包括：定位销51、折叠压板52以及拉簧53，其中，折叠压板52滑动安装于纵向滑道32中，当滑板3相对箱体1展开时，折叠压板52的端部与缓冲支杆4相抵，拉簧53一端与滑板3固定连接，另一端与折叠压板52固定连接，定位销51穿过滑板3侧壁上的通孔，与折叠压板52一体连接。参见图3、图4，在第一横向支架113上设置有与定位销51配合的凹槽1131，当滑板3相对于箱体1折叠时，定位销51恰好卡设于凹槽1131内，且在凹槽1131上还设置有用于控制定位销51下移的控制开关1132，其中，控制开关1132为电磁阀或一端位于凹槽1131内，且可相对凹槽1131相对移动的活动按钮1132。
该折叠锁定装置的具体工作过程为：当控制开关为活动按钮时，滑板处于折叠状态时，定位销卡设于凹槽内且与活动按钮相抵，如果需要使用滑板进行爬梯时，只需下按活动按钮，活动按钮会带动定位销向下移动，直至定位销的高度小于凹槽下缘，在缓冲支杆与砥柱之间的扭转弹簧作用下，该缓冲支柱与纵向导槽滑动连接的端部，会沿着纵向导槽向上移动，将滑板顶出，使滑板位于展开状态；而要进行滑板折叠时，需要向下按压折叠压板上的定位销，带动折叠压板向下运动，并使拉簧发生拉伸形变，折叠压板迫使缓冲支杆与纵向导槽滑动连接的端部沿着纵向导槽向下移动，此时再人为向内推动滑板，直至将定位销放置到凹槽处，由于折叠压板连接的拉簧要恢复原形，会拉动折叠压板向上运动，推动定位销上移，恰好卡在凹槽内与活动按钮相抵，实现滑板的位置固定；当控制开关为电磁阀时，需要控制滑板展开时，只需通过电磁阀控制定位销下移，即可，而折叠时的操作过程与控制开关为活动按钮一致，在此就不再一一描述。
上述的活动按钮操作适合外置拉杆形式的拉杆箱；在内置拉杆形式的拉杆箱 在展开滑板时，因第一横向支架和活动按钮都可能被包裹在箱包内不能用按钮展开滑板，这时就直接按压折叠压板就可以将滑板顶出。
由于上述的拉杆箱在爬梯的过程中，主要依靠滑板相对台阶的外沿凸角进行滑动，实现爬梯功能，因此为了提高该拉杆箱的使用寿命，增强滑板的耐磨性，作为技术方案的改进，参见图5，在滑板3远离箱体1的一侧侧面上设置有耐磨板33，图中示出的为在滑板3的两侧分别设置有一条耐磨板33。
上述实施例仅以箱体1下方安装的滚轮15为固定滚轮为例进行了说明，其同样可以适用于滚轮15为万向轮的情况，但由于万向轮可以实现多向运动，在爬梯时，当万向轮15与台阶的外沿凸角相接时，有可能会发生万向轮转向的问题，给爬梯带来阻碍，增大了拉杆箱爬梯时所需的拖拽力，为了解决滚轮15为万向轮时，存在的技术问题，本发明对部分部件结构进行改进，下面以一个具体案例进行详细说明。
参见图8、图9为一种爬梯式拉杆箱，该拉杆箱包括：箱体1，在箱体1的一侧固定安装有拉杆架，在拉杆架内分别安装有2个伸缩拉杆12，在2个伸缩拉杆12的端部之间连接有把手，在箱体1的底部安装有滚轮15，该滚轮15为万向滚轮，在箱体1的底面上设置有向下延伸的滑板铰轴支座16，且在箱体1的底部还设置有凹陷区域13，其中，拉杆架包括纵向平行设置的第一拉杆架和第二拉杆架以及两端分别与第一拉杆架和第二拉杆架连接的第一横向支架和第二横向支架，在第一拉杆架和第二拉杆架之间设置有砥柱2，且该砥柱2的两端分别与第一横向支架和第二横向支架固定连接，参见图9，在箱体1的底部，通过滑板铰轴支座16铰接有滑板3，参见图7，该滑板3的纵向截面呈类L形，滑板3包括：呈钝角连接的滑板主体34以及连接板35，且在滑板主体34与连接板35的连接处安装有固定脚轮6，其中，滑板主体34靠近箱体1的一侧侧面上设置有纵向导槽31，滑板3与砥柱2之间通过缓冲支杆4连接，其中，缓冲支杆4一端滑动安装于纵向导槽31内，另一端通过扭转弹簧41与砥柱2铰接，而连接板35的端部与滑板铰轴支座16铰接，且当滑板3相对箱体1折叠时，滑板3中的固定脚轮6恰好容纳于凹陷区域13中。
该拉杆箱的滑板相对箱体展开，进行爬梯时，主要依靠滑板中的固定脚轮与台阶的外沿凸角相接，万向轮主要起到辅助支撑的作用，其他的工作过程与上述滚轮为固定滚轮的工作过程一致，在此不再赘述。
同理，还可以在上述结构上增加折叠锁定装置5，具体的结构和配合结构可参照上述固定滚轮的案例，在此就不在重复叙述。
对于拉杆箱中的滚轮无论是固定滚轮，还是万向轮，都可在滑板3与箱体1铰接处固定安装有用于驱动所述滑板3移动的步进电机，在扭转弹簧41上固定安装有用于驱动缓冲支杆2移动的步进电机，用于电动实现滑板的展开和折叠。
