Description

一种具有缓震效果的悬浮模组及背包 技术领域
本实用新型涉及减震器技术领域，更具体地说，涉及一种具有缓震效果的悬浮模组及背包。
背景技术
背包是人们日常生活中的常见用品，背包在行走时会跟随身体上下晃动,产生的下沉冲击力可以达到背包本身重量的3倍之多,在长时间的行走运动中,会持续反复地对肩颈造成更大压力。为了缓解背包在行走过程中产生的冲击力，减少背包对肩颈的压力，目前市场上有三种背包，第一种依托肩带弹性体产生缓冲，第二种采用外置式机械滑轨结构，第三种采用内置单程式弹簧结构。然而，第一种弹性体肩带，无法承担高负重缓冲，且弹性体伸缩率较低，缓冲效果有限，使用周期也有限；第二种外置式机械滑轨结构本身结构复杂，成本高昂，占用空间较大；第三种内置单程式弹簧结构相对而言属于最优方案，但此类结构所采用弹簧不论一根还是两根，不论拉簧还是压簧，都是整个背负过程全程起效，而全程起效致使弹簧仅能在其本身有效伸缩伸缩范围内起作用，故而，此类方案最大问题是缓冲负重阈值较小，仅能在4-6千克起到较好悬浮缓冲效果，而负重太低如儿童童包或负重太高如户外背包、摄影器材背包等都不起作用。

具体实施方式
下面将结合本实用新型实施例中的附图，对本实用新型实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本实用新型一部分实施例，而不是全部的实施例。基于本实用新型中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本实用新型保护的范围。
为了解决现有缓震背包负重阈值小的问题，本实用新型提供了一种具有缓震效果的悬浮模组，该悬浮模组使用阈值范围大，而且占用空间小，适用范围广。
如图1-图7所示，该悬浮模组包括：壳体100、拉杆200、第一弹性组件310和第二弹性组件320，其中，壳体100上方开口且设有两个导槽130，拉杆200穿过开口与导槽130滑动连接，拉杆200可以延着导槽130上下移动。拉杆200设有一个空腔，空腔上设有活动槽240，空腔内设有活动杆250，活动杆250一端穿过空腔并可以上下活动，活动杆250上设有销轴252，销轴252可以限制活动杆250在活动槽240范围内移动。第一弹性组件310的上端与拉杆200连接，下端与壳体100连接；第二弹性组件320的上端与活动杆250连接，下端与壳体100连接。
具体的，如图4所示，销轴252设于活动杆250的上端，活动杆250向上移动到活动槽240的上端，销轴252限制活动杆250继续移动；活动杆250向下移动到活动槽240的下端，销轴252限制活动杆250继续向下移动，即活动杆250的活动距离等于活动槽240的长度。活动杆250的下端设有连接孔251，活动杆250通过连接孔251与第二弹性组件320连接。第一弹性组件310和第二弹性组件320共同组成该悬浮模组的弹性组件300，弹性组件300随着拉杆200的向上移动被拉伸。
具体的，如图8所示，当拉杆200没有拉动时，弹性组件300处于初始状态，即第一弹性组件310和第二弹性组件320均未被拉伸。第一阶段，拉杆200向上拉动，第一弹性组件310被拉伸，同时活动槽240跟着拉杆200向上移动，销轴252渐渐远离活动槽240的上端，不断向活动槽240的下端靠近，此时活动杆250相对包体保持不动，第二弹性组件320未被拉伸，此时悬浮模组达到初始负重阈值。当拉杆200拉动到一定距离，活动杆250的销轴252到达活动槽240下端，如图9所示，此时第一弹性组件310被拉伸，第二弹性组件320处于初始状态，此时悬浮模组达到第一负重阈值。第二阶段，如图10所示，拉杆200继续向上拉动，第一弹性组件310继续被拉伸，活动杆 250受到销轴252的限制，跟随拉杆200向上移动，此时，第二弹性组件320被拉伸。当拉杆200不能继续拉动时，达到悬浮模组第二负重阈值，即最大负重阈值。
以背包为例，该悬浮模组的壳体与背包的包体固定连接，悬浮模组的拉杆与背包的背带连接，悬浮模组通过弹性模组的缓震作用减少背包在行走过程中产生的冲击力，减轻背包的压力，悬浮模组与背包的连接采用现有技术。
以第一负重阈值是6千克，第二负重阈值是12千克为例。
在现有技术中，悬浮模组使用单组或者多组弹性元件，该一组或多组弹性元件均采用相同的连接方式。当背包重量在10千克或以上时，若悬浮模组采用阈值范围为2-6千克的弹性元件，则需要至少2组该弹性元件，此时，该悬浮模组的初始负重阈值至少为4千克，此方式使悬浮模组不适用于2-4千克负重的背包；若悬浮模组只采用阈值范围为6-12千克的弹性元件，虽然只需要一组该弹性元件即可，但当背包重量少于6千克时，悬浮模组不能起到缓震的作用；或者，使用一个阈值范围在2-12千克的弹性元件，则该弹性组件的初始长度和拉伸长度都会变大，占用空间会更大，同时弹性元件的振幅变大影响缓震效果。
而本实用新型的悬浮模组，只需要一组阈值范围为2-6千克的第一弹性组件310和一组阈值范围不少于6千克的第二弹性组件320，即可实现2-12千克阈值范围内的缓震效果。在一个具体实施例中，当背包负重达到初始负重阈值时，第一弹性组件310工作；当背包负重范围达到第二负重阈值时，第一弹性组件310和第二弹性组件320同时工作。在实现同样范围阈值负重的情况下，本实用新型的悬浮模组所需弹性组件的数量少，控制了悬浮模组自身的重量，同时所需拉伸长度小，占用空间小，适用范围广。
可以理解地，在其他实施例中，第一弹性组件310和第二弹性组 件320可以根据实际需要使用不同阈值范围的弹性元件，以适用更大负重阈值需求的背包。
进一步地，弹性组件300包括但不限于为拉簧，也可以是压簧，或者是拉簧和压簧的组合。
可以理解地，在不同的实施例中，第一弹性组件310和第二弹性组件320可以采用不同弹簧常数的弹簧进行组合，使初始负重阈值更小，或者使最大负重阈值更大。同时，在本实施例中，第一弹性组件310包括两根弹簧常数相同的拉簧，第二弹性组件320包括一根拉簧，第一弹性组件310和第二弹性组件320的弹簧常数不一定相同。
进一步地，壳体100包括：前壳110和后壳120，其中，后壳120上设有若干定位孔121，前壳110的内侧设有若干定位销111，前壳110通过定位销111插接于定位孔121与后壳120固定连接。前壳110与后壳120组合形成一个上端开口的壳体100，且前壳110与后壳120之间形成一个安装腔，拉杆200穿过该开口设于安装腔内。
进一步地，部分定位销111上设有凹形挂槽1111，该挂槽1111用于固定第一弹性组件310和第二弹性组件320的下端。可以理解地，连接于挂钩220和挂槽1111的第一弹性组件310、连接于活动杆250和挂槽1111的第二弹性组件320处于同一平面且互相平行，同时，第一弹性组件310和第二弹性组件320与导柱230也互相平行。
进一步地，如图所示，拉杆200为轴对称结构，上端设有连接部210。连接部210下端中间位置设有一个空腔，空腔内设有活动杆250，空腔前后位置上设有相对的活动槽240。活动杆250上下两端各有一个连接孔251，上端的连接孔251设有一个销轴252，销轴252横穿过活动槽240，限制活动杆250在活动槽240内活动，下端的连接孔251用于与第二弹性组件320连接。连接部210下端位于空腔左右两侧各设有一个挂钩220，挂钩220用于与第一弹性组件310的上端连接。连接部210两侧还各设有一个导柱230，拉杆200通过导柱230 与壳体100的导槽130滑动连接。
优选地，本实施例中连接部210、挂钩220、空腔和导柱230一体成型。可以理解地，在部分实施例中，挂钩220、空腔和导柱230也可以通过连接件与连接部210固定连接。
进一步地，壳体100还包括限位槽，限位凹槽包括设于前壳110上的第一限位槽114和设于后壳120上的第二限位槽124，第一限位槽114和第二限位槽124的位置和活动槽240的上端相对应，当销轴252处于活动槽240的最上端时，此时悬浮模组处于初始状态，第一弹性组件310和第二弹性组件320处于未拉伸也未压缩的原始状态，销轴252的两端悬挂于第一限位槽114和第二限位槽124处，使活动杆250不在重力的影响下自然下落，造成第二弹性组件320的压缩。
进一步地，导柱230位于连接部210的下端，即远离连接部210的一端，设有限位块231，导槽130的上方设有限位面131，限位块231移动至导槽130上方时受到限位面131的阻挡，避免拉杆200被拉离壳体100。
如图10所示，拉杆拉伸的一定距离时，限位块231受到限位面131的阻挡，拉杆200无法继续向上移动，此时，第二弹性组件320达到最长状态，该悬浮模组达到最大负重阈值，即第二负重阈值。
进一步地，导槽130包括：设于后壳120内侧的滑槽122和设于前壳110内侧的弧形槽112，滑槽122与导柱230滑动连接，弧形槽112设于导柱230外侧，使导柱230沿着固定方向移动。滑槽122的上端设有限位面131，导柱230延着滑槽122移动到限位面131时无法继续移动，此时第二弹性组件320被拉伸到最长状态，达到该悬浮模组的第一负重阈值。导槽130不仅可以限定导柱230的移动方向，还使拉杆200在拉动的过程中左右平衡，避免弹性组件300横向晃动，减少弹性组件300和壳体100的摩擦，防止产生噪音。
进一步地，弧形槽112的下端底面可以限制导柱230向下移动。
进一步地，在一些实施例中，该悬浮模组可以包括一个或多个导槽，相应地，包括一个或多个导柱。多个导槽和导柱的应用，可以使该悬浮模组的结构更加稳定，弹性组件300在横向上不会放生偏离，使弹性组件避免发生摩擦，产生噪音。
进一步地，壳体100上设有避让槽140，该避让槽140有前壳110上的第一凹槽113和后壳120上的第二凹槽123形成，避让槽140形成的空间用于放置第一弹性组件310和第二弹性组件320。避让槽140进一步减少弹性组件300拉伸时与壳体100产生摩擦，进而避免了噪音的产生，使用户有更好的使用体验。
进一步地，在一些实施例中，前壳110的左右两侧设有负重标示，该标示用于实时显示负重的数值。该标示标明导柱230在不同位置时，悬浮模组的负重数值，用户可以根据导柱230下端限位块231对应标示的位置，实时获取负重信息。
具体地，如图11所示，导柱230底部设置有浮动浮标，前壳110正对浮标的部分为标示115的重量数值，重量数值的左右两侧为重量刻度指示，浮标和导柱230同步移动，导柱230向上移动时，浮标也向上移动，对应显示不同的重量数值，即背包的负重情况。优选地，浮标可以采用荧光材料，使用户在黑暗环境下也能观察背包的负重情况。
进一步地，标示115设置的数量包括但不限于1组，具体地，标示115的数量可以和导柱230的数量相同，也可以少于导柱230的数量。
进一步地，在一些实施例中，前壳110为部分透明或者全透明，便于显示浮标的实时位置。
进一步地，在一些实施例中，后壳120还包括：缝制孔125，缝制孔125设于后壳120的裙边，该裙边距离后壳120的上边缘有一定距离的高度差，可以使该悬浮模组嵌入式的连接于背包包体。
进一步地，在一些实施例中，前壳110采用硬胶件，后壳120采用软胶件。在该实施例中，前壳110的弧形槽112的槽口仅能容纳限位块231的宽度，拉杆200设于弧形槽112内，拉杆200在弧形槽112内可以上下拉动，且不需要由后壳120的滑槽122受力。因此，后壳120采用软胶件并不影响拉杆200的整体拉伸。同时，硬胶件和软胶件的组合使悬浮模组在保证整体强度情况下，方便后壳裙边与包体的缝制，且不必设置缝制孔即可，同时壳体外表面和包体表面平整无凸起，使用户体验更佳。
本实用新型的具有缓震效果的悬浮模组，通过第一弹性组件310和第二弹性组合实现了不同负载情况下，该悬浮模组都能起到缓震作用，负载阈值范围大，占用空间小，适用范围广。
