Description

仿充气车轮及含该仿充气车轮的婴儿车 技术领域
本实用新型涉及车轮领域，尤其涉及一种仿充气车轮及含该仿充气车轮的婴儿车。
背景技术
随着时代的进步及生活品质的提升，婴儿车或儿童玩具的轮子有着许多不同的设计。传统的车轮具有一外胎及一内胎，外胎是由橡胶材质做成，而内胎为空心，使用时需先将内胎充气，此种充气车轮会有容易爆胎的缺点，即使不会爆胎亦有需要经常充气的麻烦。
鉴于充气车轮的缺点，仿充气车轮诞生了并得到很好的发展。仿充气车轮主要包括外胎、填充胎及轮毂，其中，填充胎是采用发泡材料制备而成，同时将填充胎套装于外胎内，并一同安装于轮毂上，无需进行打气并可使用。然而，现有的填充胎与外胎及轮毂之间没有空隙，导致填充胎受压变形时材料无空间缓冲，使得填充胎的弹性较低。
因此，亟需一种新型的仿充气车轮来解决上述问题。
发明内容
本实用新型的目的在于提供一种质量轻、弹性大的仿充气车轮。
为实现上述目的，本实用新型提供了一种仿充气车轮，包括轮毂、套装于轮毂的填充胎以及覆套于填充胎的外胎，外胎具有与外界滚动接触的滚动部和沿滚动部两侧延伸的抵接部，抵接部位于轮毂与填充胎之间，抵接部的一侧与轮毂抵接，另一侧与填充胎抵接，填充胎外表面至少一处内凹形成凹槽。
较佳地，填充胎外表面与外胎接触的位置设置有至少一处凹槽或/和填充胎 外表面与轮毂接触的的位置设置有至少一处凹槽。
较佳地，本实用新型的凹槽包括第一凹槽，填充胎外表面与外胎接触的其中一处内凹形成第一凹槽。
较佳地，本实用新型的凹槽还包括第二凹槽，填充胎外表面与外胎接触的另一处内凹形成第二凹槽。
较佳地，填充胎外表面与滚动部接触的位置内凹形成第一凹槽和第二凹槽。
较佳地，第一凹槽和第二凹槽分别靠近两抵接部设置。
较佳地，第一凹槽和第二凹槽沿滚动部的中心线呈对称设置。
较佳地，本实用新型的凹槽还包括第三凹槽，填充胎外表面与轮毂接触的其中一处内凹形成第三凹槽。
较佳地，本实用新型的填充胎朝轮毂方向延伸有凸部，凸部表面内凹形成第三凹槽。
较佳地，第一凹槽和第二凹槽位于第三凹槽的两侧。
本实用新型还提供了一种婴儿车，该婴儿车包含上述仿充气车轮。
与现有技术相比，本实用新型的仿充气车轮中，利用填充胎外表面至少一处内凹形成凹槽，使得填充胎与轮毂或/和外胎之间具有空间，以提供填充胎的材料变形时缓冲的空间，以增加填充胎的弹性。因此，该仿充气车轮中填充胎的弹性较好。

元件标号说明
100仿充气车轮，10轮毂，30填充胎，31凹槽，311第一凹槽，313第二凹槽，315第三凹槽，33凸部，50外胎，51滚动部，511凹部，512中心线，53抵接部。
具体实施方式
现在参考附图描述本实用新型的实施例，附图中类似的元件标号代表类似的元件。
请参考图1-图2，本实用新型的仿充气车轮100包括轮毂10、套装于轮毂10上的填充胎30以及覆套于填充胎30上的外胎50，使得填充胎30填充于轮毂10和外胎50之间。具体地，外胎50可由橡胶、TPE、TPR、PVC等材料制成，在本实施例中，外胎50是以橡胶硫化成型。填充胎30由发泡材料发泡而成，不需要进行打气，减少了爆胎的机会。其中，发泡材料可以为TPU、PU、EVA或PP等。外胎50具有与外界滚动接触的滚动部51和沿滚动部51两侧延伸的抵接部53，抵接部53位于轮毂10与填充胎30之间，抵接部53的一侧与轮毂10抵接，另一侧与填充胎30抵接。于本实施例中，抵接部53的外侧与轮毂10抵接，内侧与填充胎30抵接，以使得外胎50不会发生滑动。滚动部51上具有多个凹部511，既减轻了外胎50的质量又使得外胎50具有防滑功能。
请参考图3-图4，填充胎30外表面至少一处内凹形成凹槽31，比如，填充胎30外表面有一处形成凹槽31(如图3或图5所示)、填充胎30外表面有两处均形成凹槽31(如图4所示)、填充胎30外表面有三处均形成凹槽31(如图6所示)、甚至填充胎30外表面有六处均形成凹槽31等。进一步，填充胎30外表面与外胎50接触的位置设置有至少一处凹槽31或/和填充胎30外表面与轮毂10接触的的位置设置有至少一处凹槽31。也就是说，填充胎30外表面与外胎50接触的位置可单独设置一处凹槽31，也可设置一处以上的凹槽31。还可是填充胎30外表面与轮毂10接触的的位置单独设置一处凹槽31，也可设置一处以上的凹槽31。还包括在填充胎30外表面与外胎50接触的位置和填充胎30外表面与轮毂10接触的的位置均设置一处凹槽31，也可均设置一处以上的凹槽31。其中一个实施例中，凹槽31包括第一凹槽311(如图3所示)，填充胎30外表 面与外胎50接触的其中一处内凹形成第一凹槽311，第一凹槽311使得填充胎30与外胎50之间具有空间，以提供填充胎30的材料变形时缓冲的空间，以增加填充胎30的弹性。进一步，填充胎30外表面与外胎50接触的另一处内凹形成第二凹槽313(如图4所示)，同样第二凹槽313可提供填充胎30的材料变形时缓冲的空间，以增加填充胎30的弹性。其中，填充胎30外表面与滚动部51接触的位置内凹形成第一凹槽311和第二凹槽313。当然，还可以是整个滚动部51设置若干凹槽31。进一步，第一凹槽311和第二凹槽313分别靠近两抵接部53设置，不仅不影响填充胎30正常工作的强度，同时还能达到填充胎30的材料变形时往两侧缓冲的效果。更进一步，第一凹槽311和第二凹槽313沿滚动部51的中心线512呈对称设置(如图4所示)，使得填充胎30具有稳定的工作状态且填充胎30的材料变形可均匀缓冲至第一凹槽311和第二凹槽313，从而保证填充胎30弹性的稳定性。
请参考图5-图6，凹槽31包括第三凹槽315，填充胎30外表面与轮毂10接触的其中一处内凹形成第三凹槽315。当然，本实施例中，仅描述了在填充胎30外表面与轮毂10接触的位置设了一处第三凹槽315，还可以是在填充胎30外表面与轮毂10接触的位置设置多个凹槽3。第三凹槽315使得填充胎30与轮毂10之间具有空间，以提供填充胎30的材料变形时缓冲的空间，同样能增加填充胎30的弹性。也就是说可将填充胎30与轮毂10和外胎50之间单独设置有缓冲空间，比如填充胎30与外胎50之间可设有第一凹槽311或/和第二凹槽313，或是填充胎30与轮毂10之间可单独设有第三凹槽315；还可是填充胎30与轮毂10和外胎50之间均设置有缓冲空间，比如填充胎30与外胎50之间可设有第一凹槽311或/和第二凹槽313，且填充胎30与轮毂10之间可设有第三凹槽315(如图6所示)。进一步，填充胎30朝轮毂10方向延伸有凸部33，凸部33表面内凹形成第三凹槽315。更进一步，第一凹槽311和第二凹槽313位于第三凹槽315的两侧，第一凹槽311、第二凹槽313和第三凹槽315的位置连接线可近似三角形，尤其是呈等腰三角形结构较优。既保证了填充胎30的工作强度，又使得填充胎30的材料变形可均匀得缓冲到第一凹槽311、第二凹槽313和第三凹槽315中，从而提高其弹性的稳定性。
与现有技术相比，本实用新型的仿充气车轮100中，利用填充胎30外表面至少一处内凹形成凹槽31，使得填充胎30与轮毂10或/和外胎50之间具有空间，以提供填充胎30的材料变形时缓冲的空间，以增加填充胎30的弹性。因此，该仿充气车轮100中填充胎30的弹性较好。
本实用新型还提供了一种包含上述仿充气车轮100的婴儿车，具体可以为婴儿推车或婴儿拉车等。采用该仿充气车轮100的婴儿车，填充胎30的弹性较好，可提高抗震效果及安全性，实用性强。
