Description

一种可在封闭轨道中竖向拐弯的双面玩具车 技术领域
本实用新型涉及一种双面玩具车，具体说是一种可在封闭轨道中竖向拐弯的双面玩具车。
背景技术
现有的玩具车种类繁多，大多数是单朝向行走的常规玩具车，即在车体的底部设有轮子来实现行走，这种玩具车的传动结构设计也比较简单，且其功能也比较单一，趣味性不强；目前还有一种玩具车为双面玩具车，这种玩具车是在车体的底部和顶部均设有轮子，故可实现正面行走和反面行走，于是就设计出了可以供该双面车行走的封闭轨道，即含有供双面车上轮接触的上轨道和供双面车下轮接触的下轨道的轨道体，双面车可以在该封闭轨道中自由行走，但由于现有的双面车的传动结构笨重以及双面车的上下轮均与封闭轨道的上下轨道接触的缘故，所以该双面车在竖向拐弯时，由于前轮先进入竖向拐弯段而使整个车体前部抬起，此时后轮的上下轮会发生相对位移，但由于轨道高度不变，故经常会被卡住无法动弹，现有的处理方法有三种：一是省略封闭轨道的竖向拐弯段的设计，这就使得该双面车在封闭轨道行走独特性能无法体现出来；二是缩小双面车的高度或者增大封闭轨道的上下高度，即让双面车的上轮不与上轨道接触，从而给双面车在竖向拐弯段留有足够的拐弯空间而实现能竖向拐弯，但由于双面车与轨道之间有间隙，故有无法满足在竖直轨道上行驶，而且有间隙也会导致双面车在轨道中行走不平稳；三是将双面车的上下轮设计成可相对伸缩的方式，主要是采用弹簧悬挂在轮轴和车体上的方式来实现上下轮可相对弹性收缩，从而保证上下轮在竖向拐弯段受到挤压时能收缩以实现双面车不被卡死，但如此设计又进一步加重了双面车的体重，传动结构也更为复杂，在收缩过程中会影响到双面车的行驶驱动力，还增加了制造成本，而且弹簧在使用过程中有可能出现无法收缩的情况，故也同样会出现双面车在竖向拐弯处卡死的情况。
发明内容
针对上述现有技术所存在的问题，本实用新型的目的是提供一种设计巧妙，能使应用的玩具车在大弧度竖向拐弯轨道上以及在垂直轨道中平稳顺畅行走的双面玩具车。
为达到上述目的，本实用新型所采用的技术方案是：一种可在封闭轨道中竖向拐弯的双面玩具车，包括有车体、设置于车体前部的向车体上下方凸出的作为从动轮的前轮以及设置于车体后部的包括一对向车体上方凸出的上驱动轮和一对向车体下方凸出的下驱动轮的后轮，其特点是所述后轮设计成具有弹性可变形收缩的车轮，所述前轮的上下最大距离小于等于后轮最大弹性收缩后的上下驱动轮的最大距离，所述后轮在最大弹性收缩后的上下驱动轮的最大距离小于等于与该玩具车搭配的封闭轨道的高度距离，而所述后轮在未弹性收缩时的上下驱动轮的最大距离大于封闭轨道的高度距离。
其中，为了实现后轮的轮体本身能弹性变形，上述后轮的上驱动轮和/或下驱动轮的轮面上设有弹性锯齿而实现后轮可弹性收缩，故相比现有技术该方案更加简单实用，也不影响双面车的驱动力，而且弹性锯齿在双面车行走过程中与轨道面的接触为点接触，故还能有效降低车轮与轨道面的摩擦损坏。
弹性锯齿可以为各种形状的凸柱或凸粒形成，本发明的弹性锯齿为多个圆形弹性凸柱间隔环绕于软圈上而形成呈锯齿状的轮圈，所述轮圈套设在上述上驱动轮和/或下驱动轮的轮面上，故更换拆装方便。
本发明的前轮可以有多个设计方案。方案一：上述前轮为一个直径大于车体高度且向车体上下方凸出的从动轮，所述从动轮通过一转轴可转动地连接于车体前部中间位置，所述从动轮的直径小于等于后轮最大弹性收缩后的上下驱动轮的最大距离；方案二：上述前轮为一对直径大于车体高度且向车体上下方凸出的从动轮，这对从动轮通过一转轴可转动地连接于车体前部两侧位置，所述从动轮的直径小于等于后轮最大弹性收缩后的上下驱动轮的最大距离；方案三：上述前轮包括向车体上方凸出的一个上从动轮和向车体下方凸出的一对下从动轮，所述上从动轮通过一转轴可转动地连接于车体前部靠上端的中间位置，这对下从动轮通过一转轴可转动地 连接于车体前部靠下端的两侧位置，所述上下从动轮的最大垂直距离小于等于后轮最大弹性收缩后的上下驱动轮的最大距离；方案四：上述前轮包括向车体上方凸出的一对上从动轮和向车体下方凸出的一个下从动轮，这对上从动轮通过一转轴可转动地连接于车体前部靠上端的两侧位置，这对下从动轮通过一转轴可转动地连接于车体前部靠下端的中间位置，所述上下从动轮的最大垂直距离小于等于后轮最大弹性收缩后的上下驱动轮的最大距离；方案五：上述前轮包括向车体上方凸出的一对上从动轮和向车体下方凸出的一对下从动轮，上从动轮通过一转轴可转动地连接于车体前部靠上端的两侧位置，下从动轮通过一转轴可转动地连接于车体前部靠下端的两侧位置，所述上下从动轮的最大垂直距离小于等于后轮最大弹性收缩后的上下驱动轮的最大距离。
进一步为了达到更佳的行走性能，上述上驱动轮的转轴轴芯与下驱动轮的转轴轴芯共同位于同一垂直于车体的垂直截面上。
为了尽可能的减少双面车的体重以提高其行走效果，上述上驱动轮和下驱动轮通过一个传动结构驱动而实现上驱动轮与下驱动轮异向同速转动。
本实用新型由于将后轮设计成具有弹性可变形收缩的车轮，且使前轮的上下最大距离小于等于后轮最大弹性收缩后的上下驱动轮的最大距离，使车体放置于平面时有一定的向前倾斜的角度，也使后轮的上驱动轮相对下驱动轮倾斜向前，后轮在未弹性收缩时的上下驱动轮的最大距离大于封闭轨道的高度距离，从而使该双面车在轨道中其上下驱动轮均能分别上下轨道面接触，保证行走过程平稳，也能实现在竖直轨道上爬行，而后轮在最大弹性收缩后的上下驱动轮的最大距离小于与该玩具车搭配的封闭轨道的高度距离，故可保证该双面车在竖向拐弯段能顺畅通过；又由于采用多个圆形弹性凸柱间隔环绕于软圈上而形成呈锯齿状的轮圈，通过将轮圈套在后轮上即可使后轮具有弹性收缩性能，结构简单，安装便捷，也有利于更换，而且弹性凸柱在双面车行走过程中与轨道面的接触为点接触，故不影响双面车的驱动力，在提高与轨道的附着力的基础上还能减少摩擦损耗；又由于前轮作为从动轮，其作用在于导向，故前轮可以根据需要设计成各种各样的形式，采用不同车轮所对应的封闭轨道的形状也不同，适用性强， 结构造型多样化，消费者可根据自己的喜爱进行选择。本发明的双面玩具车结构简单，设计巧妙，适应于各种造型的封闭式轨道，能在封闭式轨道中平稳顺畅行走，适用性强，为双面玩具车增添了更多的玩法和乐趣。
下面结合附图和实施例对本实用新型作进一步说明。
附图说明
图1为本实用新型的立体结构示意图。
图2为本实用新型在封闭式轨道中的立体结构示意图。
图3为图2简略轨道且双面玩具车处于水平段处的侧面结构示意图。
图4为图2简略轨道且双面玩具车处于拐弯段处的侧面结构示意图。
具体实施方式
如图1至图4所示，本实用新型可在封闭轨道中竖向拐弯的双面玩具车，包括有车体1、设置于车体1前部的向车体1上下方凸出的作为从动轮的前轮2以及设置于车体1后部的包括一对向车体1上方凸出的上驱动轮32和一对向车体1下方凸出的下驱动轮31的后轮3，其中后轮3设计成具有弹性可变形收缩的车轮，前轮2的上下最大距离小于等于后轮3最大弹性收缩后的上下驱动轮的最大距离，后轮3在最大弹性收缩后的上下驱动轮的最大距离小于等于与该玩具车搭配的封闭轨道4的高度距离，而后轮3在未弹性收缩时的上下驱动轮的最大距离大于封闭轨道4的高度距离，从而使该双面车在轨道4中其上下驱动轮均能分别上下轨道面接触，保证行走过程平稳，也能实现在竖直轨道上爬行，也可保证该双面车在竖向拐弯段能顺畅通过。
如图1所示，该实施例的上驱动轮32和下驱动轮31的轮面上都设有弹性锯齿30而实现后轮可弹性收缩，弹性锯齿30为多个圆形弹性凸柱间隔环绕于软圈上而形成呈锯齿状的轮圈，使用时将轮圈套设在上驱动轮32和下驱动轮31的轮面上，更换拆装方便，相比现有技术该方案更加简单实用，也不影响双面车的驱动力，而且弹性锯齿30在双面车行走过程中与轨道面的接触为点接触，故还能有效降低车轮与轨道面的摩擦损坏。该实施例的前轮2采用的方案是该前轮2包括向车体1上方凸出的一对上从动轮22和向车体1下方凸出的一对下从动轮21，上从动轮22通过一转轴可转动地连接于车 体1前部靠上端的两侧位置，下从动轮21通过一转轴可转动地连接于车体1前部靠下端的两侧位置。该实施例上驱动轮32的转轴轴芯与下驱动轮31的转轴轴芯共同位于同一垂直于车体1的垂直截面上，而且上驱动轮32和下驱动轮31通过一个传动结构驱动而实现上驱动轮32与下驱动轮31异向同速转动。
如图3和图4所示，图中的标识D即为前轮2的上下从动轮的最大垂直距离，我们假设图3状态下的后轮3的弹性锯齿恰好不发生弹性变形，此时后轮3在未弹性收缩时的上下驱动轮的最大距离即为上下驱动轮分别与上下轨道面接触点的连线距离，图中用L标识，而上下轨道的高度用H标识，将弹性锯齿30的最大弹性收缩量用R表示，那么，从图3中可知，D很明显小于L-R，所以将车体1放置在水平面上时，该车体1呈向前倾斜的状态，故后轮3的上驱动轮32会相对下驱动轮31处于靠前的位置，此时L大于H；如图4所示，图4状态下的车体1为前轮2进入竖向拐弯段而后轮3仍处于水平轨道段的状态，此时由于前轮2被抬升，故后轮3的上驱动轮32会相对下驱动轮31向后位移，故弹性锯齿30开始发生弹性收缩，当上驱动轮32位移到下驱动轮31的正上方时，如图4的状态，此时上下驱动轮分别与上下轨道面接触点的连线距离等于H，而且此时的弹性收缩最为严重，故为了避免双面车在此处被卡住，那么弹性收缩的量必须小于等于R，也即是L-R必须小于等于H，才能保证不被卡住。
尽管本实用新型是参照具体实施例来描述，但这种描述并不意味着对本实用新型构成限制。参照本实用新型的描述，所公开的实施例的其他变化，对于本领域技术人员都是可以预料的，这种的变化应属于所属权利要求所限定的范围内。
