具体实施方式
结合以下实施例对本发明作进一步描述。
实施例1
本发明的一种用于安装在玩具车上的车轮架的具体实施方式之一，如图1和图2所示，其结构包括安装件3和车轮4，横向转动轴32设于安装件3的两端且与安装件3一体成型，车轮4绕横向转动轴32转动，以带动车轮架1朝玩具车行驶方向运动。车轮架1设有纵向转动结构，该纵向转动结构包括纵向转动轴31，纵向转动轴31设于安装件3的中部且与安装件3一体成型。如图4所示，车轮架1还设于与玩具车的车本体7可拆卸连接的连接件2， 该纵向转动结构还包括与纵向转动轴31配合的轴孔21，轴孔21设于连接件2。
安装件3通过纵向转动结构与连接件2转动连接，且纵向转动结构使得安装件3绕以玩具车行驶方向为轴向的纵向转动轴31线转动，进而使得车轮4通过纵向转动结构在垂直于玩具车行驶方向的平面内转动。当玩具车在弯曲变形的轨道上行驶时，只需车轮4自身随轨道的弯曲变形在平面内做相应的转动，而无需要带动整个车本体7进行转动，这使得玩具车能够在螺旋型轨道上行驶地更为顺畅，并且使得车轮4与轨道面之间的摩擦力减小，提高了玩具车的行驶速度，同时还降低了车轮4与轨道面的磨损程度，延长了玩具车的使用寿命。
如图4所示，连接件2安装于车本体7的头部，且连接件2与车本体7可拆卸连接，不仅便于车轮架的更换和维修，而且增强玩具车的互换性和多样性。
如图1和图2所示，车轮架1还包括与安装件3可拆卸连接的导轮架5，导轮架5的两端分别设有与轨道的侧壁滚动接触的导向轮6，导向轮6起到导向作用，能够有效减少转弯时车轮4与轨道面之间的摩擦力，使玩具车的转弯更加顺畅。本实施例中，导轮架5与安装件3以卡接的方式连接，具体的，如图2和图3所示，导轮架5设有卡孔51，安装件3设有与卡孔51卡接的卡块33，导轮架5还设有弹性卡板52，弹性卡板52设有卡凸53，安装件3设有与卡凸53卡接的卡槽34。卡接时，将导轮架5的卡孔51与安装件3的卡块33对齐，按压导轮架5或者安装件3使卡块33卡在卡孔51内，同时弹性卡板52的卡凸53卡在安装件3的卡槽34内，即可将导轮架5与安装件3牢固的卡接在一起；需要拆卸时，向外拌动弹性卡板52，使卡凸53与卡槽34脱离，然后向上推动导轮架5或向下推动安装件3，使得卡块33与卡孔51脱离，即可方便、快捷地实现导轮架5与安装件3的拆卸。
本实施例中，位于导轮架5两端的两个导向轮6的外侧边之间的间距大于位于安装件3两端的两个车轮4的外侧边之间的间距，并且两个导向轮6的外侧边之间的间距约等于轨道的宽度。导向轮6的设置可有效避免车轮4与轨道的侧壁接触，进而减少车轮4与轨道面间的摩擦力，使得玩具车行驶的更为顺畅，并且导向轮6的设置还可对车轮4的横向方向进行限位，防止车轮4晃动，从而提高玩具车行驶的稳定性。
为了进一步地提高行驶性能，减少车轮4与轨道面的摩擦力，车轮4可更换为另一种车轮8，请见图8，其结构包括轮毂9和滚轮10，滚轮10安装在轮毂9的轮面上且能够相对轮毂9转动，滚轮10的数量有多个，多个滚轮10均匀环布于轮毂9的轮面，滚轮10的部分外凸出于轮毂9的轮面，以使得车轮8通过滚轮10与轨道承重壁滚动接触，(承重壁具体为轨道承载玩具车重量的内壁)，这样可有效减少车轮8与轨道承重壁之间的接触面积，从而可减小车轮8的摩擦阻力，提高车轮8的行驶速度。
实施例2
本发明的一种用于安装在玩具车上的车轮架具体实施方式之二，如图5和图6所示，本实施例的主要技术方案与实施例1相同，在本实施例中未解释的特征，采用实施例1中的解释，在此不再进行赘述。本实施例与实施例1的区别在于，导轮架5设置在横向转动轴32上，且导轮架5位于车轮4的外侧，导轮架5包括固定部和与固定部垂直连接的安装部，固定部与横向转动轴32固定连接，安装部的上下两端分别设有与轨道的侧壁滚动接触的导向轮6，两个导向轮6为同轴设置，在转弯时，两个导向轮6同时与轨道侧壁接触，有效防止玩具车侧翻，提高玩具车转弯时的稳定性。导向轮6的设置还可有效避免车轮4与轨道侧壁的接触，进而减少车轮4与轨道间的摩擦力，使得玩具车行驶的更为顺畅，并且导向轮6的设置还可对车轮4的横向方向进行限位，防止车轮4晃动，从而提高玩具车行驶的稳定性。
如图7所示，本实施例中的车轮架1通过连接件2与车本体7可拆卸连接，不仅便于车轮架1的维修和更换，同时也增强了玩具车的互换性和多样性。
最后应当说明的是，以上实施例仅用以说明本发明的技术方案，而非对本发明保护范围的限制，尽管参照较佳实施例对本发明作了详细地说明，本领域的普通技术人员应当理解，可以对本发明的技术方案进行修改或者等同替换，而不脱离本发明技术方案的实质和范围。
