具体实施方式
为了使本领域的技术人员更好地理解本发明的技术方案，下面结合附图和具体实施例对本发明作进一步的详细说明。
请参考附图1-3，其中，图1为本发明所提供学步车的结构示意图；图2为图1中调节卡座与调节支架配合的剖视图；图3为图1中调节支架的结构示意图。
在一种具体实施例中，本发明提供一种学步车，包括上盘座椅1和底盘2，还包括用于调节上盘座椅1与底盘2之间垂向距离的高度调节装置3，其一端与上盘座椅1连接，另一端与底盘2连接。
本实施例中，通过调节高度调节装置3来改变上盘座椅1与底盘2之间的垂向距离，使得该学步车具有不同的高度，适用于不同高度的婴儿，与现有技术中仅有一种高度的学步车相比，具有更高的适用性。
具体地，该高度调节装置3可包括垂向设置的调节卡座31和调节支架32，且该调节支架32一端与底盘2连接，另一端与调节卡座31连接；且 调节支架32与调节卡座31中一者设有第一挂钩，另一者设有垂向分布的至少两个挂钩槽311，以使第一挂钩卡接于各挂钩槽311，当第一挂钩卡接于不同挂钩槽311时，调节支架32位于调节卡座31之外的部分的长度不同，即该高度调节装置3处于不同的档位，学步车具有不同的高度。
当然，该高度调节装置3并不仅限于包括调节卡座31和调节支架32，也可采用本领域常用的其它高度调节装置，例如，上盘座椅1与底盘2之间可设有具有齿部的升降调整杆及套筒，通过二者齿部的相互啮合实现二者的相对运动，从而调节学步车的高度。但是，本实施例中的调节卡座31与调节支架32相互配合的调节方式结构简单，易于实现。
更具体地，如图3所示，调节支架32上端的两侧均设有朝向调节支架32外侧延伸的第一凸台321，该第一凸台321为上述的第一挂钩；同时，如图2所示，各挂钩槽311分别设于调节卡座31的两侧，即包括两列挂钩槽311，且每一列的挂钩槽311个数为至少两个，同时，两列挂钩槽311中对应的两个挂钩槽311位于同一高度，这两个挂钩槽311定义为一个挂钩槽组，当学步车调整高度时，第一凸台321卡接于该挂钩槽组。
当然，调节支架32也可仅设有一个第一凸台321，相应地，调节卡座32也可仅设有一列挂钩槽311，但是，本实施例中，设有两个第一凸台321和两列挂钩槽311时，调节较稳定，可保证学步车的安全性。
进一步地，如图3所示，调节支架32上端的两侧分别设有沿与第一凸台321相对的方向延伸的第二挂钩322，位于调节卡座31最下端的两个挂钩槽311定义为末端挂钩槽组，调节卡座31中部的下端还设有与该末端挂钩槽组对应的第二凸台312，以使第一凸台321卡接于该末端挂钩槽组时，第二挂钩322卡接于第二凸台312。
当该学步车需要的高度较高时，高度调节装置3位于最低的档位，此时，第一凸台321卡接于末端挂钩槽组，该调节支架32与调节卡座31配合的长度较小，调节支架32容易从调节卡座31中脱出。本实施例中，当第一凸台321卡接于末端挂钩槽组时，第二挂钩322同时卡接于第二凸台312，从而防止第一凸台321从末端挂钩槽组中脱出，保证学步车高度调节装置3位于最低档位时的安全性。
更进一步地，如图3所示，调节支架32可为开口上大下小的“U”型结 构，且其在外力的作用下能够向内收缩；相应地，调节卡座31可为与调节支架32相适配的倒梯形结构，且其内部中空，各挂钩槽311与第二凸台312均设于调节卡座31的内壁。
另外，在高度调节过程中，当第一凸台321卡接于垂向的不同挂钩槽311时，第二挂钩322沿调节支架32的内部空腔垂向运动。
当然，调节卡座31和调节支架32的结构并不仅限于此，也可为其它垂向设置的结构，例如，调节支架32也可为设有第一凸台321的矩形结构，但是，本实施例中，调节支架32的“U”型结构使得当学步车调整高度时，用手紧握调节支架32，即可改变“U”型结构两端的距离，使得第一凸台311从一个挂钩槽组移动至另一个挂钩槽组，因此，学步车调节高度的过程不需要设置其它的驱动装置，从而使得学步车结构简单，且可保证安全。
具体地，如图2所示，挂钩槽311的个数可为六个，即调节卡座31设有三个挂钩槽311组。如此设置，图2所示的实施例中，该高度调节装置3具有三个档位，该学步车具有三种不同的高度，可适用于三种高度范围的婴儿使用。
可以理解，通过改变挂钩槽311的个数，可改变高度调节装置3所具有的档位个数，随着挂钩槽311个数的增加，高度调节装置3所具有的档位个数也增加，从而使得该学步车的适用性提高。
当然，该挂钩槽311的个数可根据需要任意设置，此处不作限定。
请继续参考附图4和5，其中，图4为图1中调节卡座与连接支架配合的结构示意图；图5为图1中学步车收合后的结构示意图。
同时，该高度调节装置3还可包括连接支架33，该连接支架33的一端焊接于调节卡座31的上端，另一端铰接于上盘座椅1，同时，调节支架32铰接于底盘2。
如此设置，当不使用学步车时，将调节支架32从调节卡座31中脱出，然后将调节支架32和连接支架33向学步车内部旋转90°，此时，学步车处于收合状态，如图4所示。收合后的学步车上盘座椅1与底盘2贴合，垂向占用空间较小，同时，周向仅占用与底盘2同样大小的空间，因此，通过该结构收合后学步车占用空间较小。
进一步地，该学步车可包括四组均匀设置于上盘座椅1与底盘2之间 的高度调节装置3。
当然，该高度调节装置3的设置个数也可为任意，考虑到学步车的安全性，可设置为偶数个均匀分布于上盘座椅1与底盘2之间的高度调节装置3。
以上各实施例中，调节支架32和连接支架33为铁支架，调节卡座31为塑胶卡座。当然，也可为本领域其它常用的材料，此处不作限定。
本发明还提供一种学步车的高度调节装置，该学步车还包括与该高度调节装置3连接的上盘座椅1与底盘2；其中，高度调节装置3包括垂向设置的调节卡座31和调节支架32，且调节支架32一端与底盘2连接，另一端与调节卡座31连接；且调节支架32与调节卡座31中一者设有第一挂钩，另一者设有垂向分布的至少两个挂钩槽311，以使第一挂钩卡接于各挂钩槽311。
以上对本发明所提供的一种学步车及其高度调节装置均进行了详细介绍。本文中应用了具体个例对本发明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发明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，在不脱离本发明原理的前提下，还可以对本发明进行若干改进和修饰，这些改进和修饰也落入本发明权利要求的保护范围内。
