Description

行李箱的避震结构 技术领域
本发明涉及一种避震结构，更具体的涉及一种行李箱的避震结构。
背景技术
现有技术中的行李箱避震轮组一般是在轮子上设置减震橡胶，但轮子的橡胶变形幅度有限，在剧烈震荡时，难以消除产生的冲击力。对于一些要求减震性能较高的行李箱，现有的减震轮子难以满足需求。
现有技术中，公开号为CN205780569U的专利文献公开了一种用于行李箱上的避震轮组，其技术方案为所述轮组组件与所述固定座之间通过一避震轴组件相连接，所述避震轴组件包括一转轴、套装在所述转轴上的避震弹簧和套装在所述转轴上的滑套，所述滑套与所述固定座固定连接，所述转轴的一端与所述轮组组件固定连接，另外一端穿过所述滑套，并安装有限位螺母，所述避震弹簧一端与所述固定座相抵靠，另外一端与所述滑套相顶靠。该发明设置避震轴组件，并且轮组组件与固定座之间通过该避震轴组件进行避震，避震轴组件具有较大的减震行程，在剧烈震动时能够消除轮组组件产生的冲击力，保护行李箱中的物品。
上述技术方案中，虽然能够达到减震效果，但是还是存在着缺陷：1、转轴的下端与轮组组件固定，上端与固定座滑动配合，因此避震轴组件在减震的过程中，转轴的上端会露出于固定座并滑至固定座的上端，导致固定座在与行李箱连接装配时，需在行李箱上预留避让空间，以供转轴的上端滑动。而该避让空间的设置，会与行李箱的内部空间相互干涉，影响行李箱的结构设计，甚至影响到行李箱内部物品的摆放。2、该技术方案中的弹簧在被压缩后，还是存在着较长的轴向距离，因此在固定座和轮组组件之间需预留出该距离，导致固定座与轮组组件的距离更大，降低了固定座与轮组组件之间的结构强度。

针对现有技术的不足，本发明提供了一种行李箱的避震结构，能够达到有效且稳定的避震效果。

发明的有益效果
有益效果
本发明的优点为：转轴的上端与固定座固定，下端相对轮组组件可移动，在转轴上下移动减震的过程中，转轴的上端不会干涉到行李箱，因此固定座与行李箱在安装时，在固定座与行李箱之间无需考虑对转轴的移动预留空间，便于固定座的安装以及便于行李箱的结构设计；同时转轴的下端相对于轮组组件下移后，也不会对轮组组件的各部件产生干涉。
对附图的简要说明
附图说明
图1为本实施例所提供的行李箱的避震结构的剖视图。
实施该发明的最佳实施例
本发明的最佳实施方式
结合图1对本发明行李箱的避震结构作进一步的说明。
一种行李箱的避震结构，包括固定座1、轮组组件6和减震轴组件，其特征是：所述减震轴组件包括转轴2和弹性件3。
轮组组件6包括基座61和安装于基座61两侧的滚轮62，基座61上具有向上凸起的导向块611，固定座1的下侧具有与导向块611导向配合的导向套11，导向块611上具有贯穿基座61上下面的装配孔5。
所述转轴2的上端轴向限位固定于固定座1内与导向套11同轴的安装孔，下端可移动装配于轮组组件6的装配孔5内，以及装配孔5内具有限定转轴2上移脱离装配孔5的限位部位53。
所述弹性件3套装于转轴2上，并且弹性件3的上端抵靠于固定座1或是转轴2，下端抵靠于轮组组件6，以对固定座1以及转轴2形成弹性支撑。
上述结构下，基座61处于悬空状态，以及基座61的下侧没有安装任何部件，因此转轴2的下端相对于基座61移动时，并不会对轮组组件6中的部件产生干涉；同时转轴2的上端与固定座1固定，因此节省了固定座1与行李箱之间预留空间的设置。综上所述，本发明的结构设计更为合理、优化，便于生产、组装以及使用。
本实施例进一步设置为：所述装配孔5包括供转轴2轴向滑动装配的导向段51和供转轴2下端下移后容纳的避让段52。该避让段52的设置，即为对转轴2的下端进行空间预留，减震过程中，转轴2的下端进入到避让段内，并隐藏于避让段内。该避让段的设置，并不会对任何部件产生干涉影响，因此相对于现有技术结构更为合理。
本实施例进一步设置为：导向段51的直径小于避让段52的直径，因此限位部位53即为导向段51和避让段52之间形成的限位台阶，以及转轴2的下端具有能够抵 靠至限位台阶的下外翻铆边22。为了加强结构强度，在下外翻铆边22上还配合有垫片7。该结构下，当垫片7上移抵靠至限位台阶时，转轴2无法继续上升，对转轴2起到上升限位的效果。
作为转轴2上升限位的另一实施方式为：装配孔5内插装限位杆，转轴2的下端具有限位外台阶或是限位翻边。当转轴2上升时，限位外台阶抵靠到限位杆时，转轴2无法继续上升。
本实施例进一步设置为：所述弹性件3为塔形弹簧。在减震时，该塔形弹簧能够被压缩成一个面，相对于现有技术中的弹簧，显著降低了被压缩后所占用的轴向距离，从而进一步节省了轮组组件6与固定座1之间空间的预留，同时缩小了固定座1与轮组组件6之间的间距，提升了两者之间的稳定性；另一方面，塔形弹簧每一段的受力均不相同，即逐级递加，使其在变形减震时更为稳定。
本实施例进一步设置为：所述转轴2具有外台阶23，所述塔形弹簧的上端抵靠于外台阶23。转轴2的上端具有上外翻铆边21，该外台阶23与上外翻铆边21之间形成与固定座1的安装孔轴向限位配合的环槽。
本实施例进一步设置为：所述轮组组件6具有垫设于装配孔5的上端口处的金属旋转垫片4，所述塔形弹簧的下端抵靠于所述旋转垫片4上。塔形弹簧的上端和下端分别抵靠在外台阶23和旋转垫片4上，能够提升轮组组件6相对于固定座1转动的稳定性。
本实施例进一步设置为：所述旋转垫片4具有限位围壁41。该围壁41能够将塔形弹簧的下端限定在旋转垫片7内，保证轮组组件6转动的稳定性。
