本发明提供的双向性避震减压背负系统，其中的避震减压装置可以随着 背袋的上下振动而振动， 对背袋的振动进行緩冲， 以使背袋的振动不会直接 作用到背板上， 因此可以有效的减轻背包负重对使用者身体所造成的伤害， 大大提高了背包的舒适性。
在具体实现中， 所述左杆 20上套接的弹性部件 205、 206、 207、 208以 及所述右杆 21上套接的弹性部件 215、 216、 217、 218为弹簧。
在一些实施方式中， 本发明可以选择是否让弹性部件 205、 206、 207、 208以及 215、 216、 217、 218起作用， 也即本发明还可以控制弹性部件 205、 206、 207、 208以及 215、 216、 217、 218不起作用， 这样整个背负系统相对 稳定，适用于不需要防震的情况，本发明也可以控制弹性部件 205、 206、 207、 208以及 215、 216、 217、 218起緩冲作用， 适用于需要防震的情况。
详见图 6和图 7, 图 6为本发明提供的双向性避震减压背负系统中避震 减压装置的又一结构示意图， 图 7为图 6的分解图。

如图 8所示， 所述支撑杆 24在旋转开关 23的控制下呈竖直状态时支撑 所述横杆 220以使所述横杆 220和所述横杆 222之间的相对距离固定。具体 的， 当旋转开关 23关闭时， 所述支撑杆 24呈现竖直状态支撑所述横杆 220 以使所述横杆 220和所述横杆 222之间的相对距离固定， 此时， 避震减压装 置上的弹性部件不起作用， 背负系统相对稳定。
参见图 9, 图 9为本发明提供的双向性避震减压背负系统中避震减压装 置的又一结构示意图。
如图 9所示， 当旋转开关 23开启时， 所述支撑杆 24呈现水平状态， 此 时支撑杆 24无法支撑所述横杆 220,此时，避震减压装置上的弹性部件起作 用， 背负系统具备防震功能。
在其他的实施方式中 （图未示）， 所述支撑杆 24在旋转开关 23的控制 下呈竖直状态时支撑所述横杆 221以使所述横杆 221和所述横杆 221之间的 相对距离固定。
具体的， 当旋转开关 23关闭时， 所述支撑杆 24呈现竖直状态支撑所述 横杆 221以使所述横杆 221和所述横杆 222之间的相对距离固定， 此时， 避 震减压装置上的弹性部件不起作用， 背负系统相对稳定。 当旋转开关 23开 启时，所述支撑杆 24呈现水平状态，此时支撑杆 24无法支撑所述横杆 221， 此时， 避震减压装置上的弹性部件起作用， 背负系统具备防震功能。
参见图 10, 图 10为本发明提供的避震减压装置中的旋转开关以及支撑 所述支撑杆 24的一端与旋转开关 23连接， 另一端端头内凹， 这样在支 撑杆 24呈现竖直状态的时候， 其凹槽的地方用于卡住所述横杆 220或者横 杆 221 , 以使所述横杆 220或者横杆 221固定。
本实施例中， 为了使背袋 3与背板 10相套接， 采用了创新结构的磁扣 结构。 具体的， 所述背袋 3的紧固件 30、 31、 32、 33具体为结构相同的磁 扣套 34, 所述避震减压装置 2的紧固件 203、 213、 204、 214具体为结构相 同的磁扣块 14; 所述磁扣套 34和所述磁扣块 14分别对应套接。
如图 11、 12所示， 为设置在背袋 3上的磁扣套 34的结构示意图。 磁扣 套 34包括固定板 341、 底座 342以及套夹 343 , 底座 342设置在固定板 341 上， 套夹 343设置在固定板 341和底座 342的连接处。
固定板 341 是多边状板体， 形状对称设置， 其上具有用于将磁扣套 34 与附袋 3连接固定的安装孔位（如图所示圓孔， 未标号）。
底座 342是设置在固定板 341顶端的矩形块结构，在底座 342的内部开 设用于容置磁铁 340的腔室 3421 , 该腔室 3421的形状与磁铁 340的形状适 应匹配， 为矩块状， 其可固定磁铁 340在其中。 置于腔室 3421中的磁铁 340 将使底座 342连同与其接连的套夹 343产生磁极。
套夹 343为一槽腔结构， 包括围挡在底座 342—侧面的相对设置的两板 体 3432以及一端板 3431。套夹 343在如图 11所示的底部和一侧端分别设置 开口， 套夹 343具有定位和卡持的作用。 本实施例中， 构成该套夹 343的一 板体设置在固定板 341和底座 342的连接处， 另一板体自底座 342的一侧转 角延伸， 设置与固定板 341相平行， 端板 3431设置在上述两相对平行设置 的板体 3432间将该套夹 343的一端侧开口封闭。 套夹 343的侧开口端与上 述腔室 3421的开口方向设置在同一侧，即腔室 3421的开口方向与端板 3431 设置在底座 342相对的两侧面。
再请参照图 13、 14所示， 为设置在背板 10上的磁扣块 14的结构示意 图。 磁扣块 14包括固定板 141、 锁块 142和连接板 144, 连接板 144连接在 固定板 141上， 锁块 142和连接板 144固定连接为一体。 锁块 142和固定板 141的位置设置相对，在其间设置一定的距离使形成一条形缝隙（卡位 143 ), 该缝隙的作用是使上述磁扣套 34的套夹 343能够插置在其中进行卡持。
固定板 141的形状和结构与上述磁扣套 34的固定板 341的形状和结构 大致相同， 亦具有用于将磁扣块 14与背板 10连接固定的安装孔位。
锁块 142设置在固定板 141的底端， 在其内部设置与上述磁扣套 34的 底座 342功能相同的腔室 1421 ,置于该腔室 1421中的磁铁 140可使锁块 142 的整体产生磁极。 锁块 142的端部亦具有一限位板 1422 , 该限位板 1422在 当磁扣套 34的套夹 343与磁扣块 14的锁块 142相装配时可将套夹 342的侧 开口端封闭。 本实施例中， 限位板 1422与腔室 1421的开口方向设置在同一 侧。 锁块 142的尺寸与套夹 343的尺寸相适配以满足装配需要， 具体的， 锁 块 142的长宽尺寸与套夹 343的长宽尺寸相同，锁块 142的高度尺寸与套夹 343的腔槽深度尺寸相同。
本发明的优选实施方式中，锁块 142的端侧设置限位槽 1423 ,该限位槽 1423的开设方向与所设置的限位板 1422的方向平行， 并垂直于固定板 141 ; 套夹 343在其两相对设置的板体 3432上设置与上述限位槽 1423位置相对应 的凸起件 3433 ,该凸起件 3433可在锁块 22与套夹 343适配套接时卡持在限 位槽 1423中。 所设置的凸起件 3433与限位槽 1423的装配结构和上述设置 的限位板 1422的限位结构可以增强磁扣套 34和磁扣块 14连接时沿套夹 343 或锁块 142延伸方向 （如图所示左右方向） 的锁紧强度， 使两者不易滑脱。
磁扣套 34与磁扣块 14装配时 ,请参照图 15所示 ,将磁扣套 34套夹 343 的底开口端朝向磁扣块 14具有锁块 142的方向进行插置（如图所示的纵向 套接）， 由于固定板 141和锁块 142间具有的条形缝隙（卡位 143 )的尺寸刚 好设置成套夹 343外侧板体的尺寸相同，锁块 142可以从套夹 343的底开口 端全部滑入并插置在套夹 343 中， 由于在腔室 3421、 1421 中放置了磁极方 向相反的磁铁，底座 342连同与其接连的套夹 343和锁块 142间所产生的相 互吸引的作用力可以加速磁扣套 34和磁扣块 14间的装配。 当锁块 142完全 滑入套夹 343中后， 套夹 343的两相对板体 3432分别夹持在锁块 142的两 相对侧体上 (其中一板体卡持在卡位 143中）。
锁块 142与套夹 343适配套接后， 磁扣套 34的固定板 341分别抵顶在 磁扣块 14锁块 142的底部连接板 144和限位板 1422的侧端， 磁扣块 14的 固定板 141抵顶在套夹 343的端板 3431上。 同时， 锁块 142的限位板 1422 抵顶在套夹 343的侧开口端，套夹 343的端板 3431抵顶在锁块 142的端侧。 套夹 343的底面与锁块 142的顶面通过磁铁产生的相互吸引的作用力对接锁 紧为一体。 至此， 完成了磁扣套 34和磁扣块 14间的匹配固定。
当锁块 142完全滑入套夹 343中后， 磁扣套 34的底座 342和磁扣块 14 的锁块 142大致为中心对称布置， 置于底座 342中磁铁 340的重心位置与置 于锁块 142中磁铁 140的重心位置并不在同一直线上， 也就是说， 固定后的 磁扣套 34和磁扣块 14中的磁铁是相平行但位置交错布置的，这使得套夹 343 和锁块 142间产生相向方向的作用力， 使套夹 343朝向锁块 142的限位板 1422的方向吸附， 也就是上述锁块 142的限位板 14224氏顶在套夹 343的侧 开口端， 套夹 343的端板 3431抵顶在锁块 142的端侧的状态。
由于使用者在背负背包时， 背袋通常主要系在纵向（即沿使用者身高的 上下方向）上运动， 本实施例的磁扣结构在纵向的锁紧设置可以牢固地将背 袋固定在背板上。 但使用过程中， 背袋仍然会发生横向的运动（例如随使用 者走路或跑步动作背袋会左右摆动）， 因此需要针对背袋横向的运动在磁扣 结构上做相应设置， 否则背袋极易在横向上脱落， 将大大降低本实施例磁扣 结构的使用效果。
本实施例中， 对于防止背袋在横向上从背板上脱落， 采取了三种方式： 一是通过限位板 1422在左右方向一侧上堵死，二是通过凸起件 3433与限位 槽 1423 的卡持， 三是通过互相平行但错开一段距离布置的两磁铁间的相向 作用力。 相对于纵向上的运动， 横向的运动幅度较小， 上述的设置能有效地 防止背袋在使用中左右摆动时的脱落。
当需要将磁扣套 34和磁扣块 14拆卸时， 使用垂直于套接方向 (亦即磁 扣套 34朝向其端板 3431或磁扣块 14朝向限位板 1422的方向 ,如图所示的 左右方向）方的外力， 使套夹 343的凸起件 3433从锁块 142的限位槽 1423 中脱离， 该外力同时需大于磁扣套 34和磁扣块 14中的磁铁相向作用力， 当 磁扣块 14的锁块 142从磁扣套 34的套夹 343的侧开口端中全部脱离即完成 拆卸。
当然， 可理解的是， 除了磁扣的套接方式之外， 还可以在背袋 3顶部设 置挂钩， 在背板 10顶部对应设置挂环， 通过挂钩挂在挂环里实现将背袋 3 安装在背板 10上。 此外， 在背袋 3顶部和背板 10顶部对应设置魔术贴， 通 过贴合方式实现将背袋 3安装在背板 10上。
参见图 16和图 17 , 本发明提供的双向性避震减压背负系统的背板 10 包括： 内面 100和外面 101 ;
所述避震减压装置 2内置在所述背板 10的内面 100和所述外面 101之 间的空间中， 所述外面 101上设置有与所述避震减压装置 2的磁扣块 203、 213、 204、 214位置相对的四个开口 1010、 1011、 1012、 1013。 所述避震减 压装置 2的磁扣 203、 213、 204、 214分别贯穿所述外面 101上开设的四个 开口 1010、 1011、 1012、 1013 , 与背袋 3的磁扣套 30、 31、 32、 33套接， 实现背袋 3与背板 10的紧固连接。
参见图 18,为本发明提供的双向性避震减压背负系统的一个应用效果示 意图。
如图 18所示， 旋转开关 23处于开启状态， 支撑杆 24属于水平位置， 横杆 220和横杆 222之间的相对距离是可变的。 当本发明的背负系统的避震 减压装置 2的紧固件 203、 204、 213、 214没有受到外界的作用力， 其左杆 20上的弹簧 205和弹簧 207, 以及右杆 21上的弹簧 215和弹簧 217处于正 常状态， 左杆 20上的弹簧 206和弹簧 208, 以及而右杆 21上的弹簧 216和 弹簧 218也处于正常状态， 此时背负系统并没有受到外力作用， 或者其既受 到向上的作用力， 又受到向下的作用力， 但其综合受力为零或者很小时， 该 背负系统基本处于平稳状态。
参见图 19,为本发明提供的双向性避震减压背负系统的又一应用效果示 意图。
如图 19所示， 旋转开关 23处于开启状态， 支撑杆 24属于水平位置， 横杆 220和横杆 222之间的相对距离是可变的。 当背负系统处于振荡状态， 受到向上的压力时， 其避震减压装置 2的紧固件 203、 204、 213、 214受到 向上的作用力， 其左杆 20上的弹簧 205和弹簧 207 , 以及右杆 21上的弹簧 215和弹簧 217处于压缩状态， 而左杆 20上的弹簧 206和弹簧 208, 以及而 右杆 21上的弹簧 216和弹簧 218此时处于伸长状态， 由于弹簧的緩冲作用， 使得避震减压装置 2与背板 10的相对位置是固定的， 也即振荡不会直接作 用到背板 10上， 因此可以有效的减轻背包负重对使用者身体所造成的伤害， 大大提高了背包的舒适性。
参见图 20,为本发明提供的双向性避震减压背负系统的又一应用效果示 意图。
如图 20所示， 旋转开关 23处于开启状态， 支撑杆 24属于水平位置， 横杆 220和横杆 222之间的相对距离是可变的。 当背负系统处于振荡状态， 受到向下的压力时， 其避震减压装置 2的紧固件 203、 204、 213、 214受到 向下的作用力， 其左杆 20上的弹簧 205和弹簧 207 , 以及右杆 21上的弹簧 215和弹簧 217处于伸长状态， 而左杆 20上的弹簧 206和弹簧 208, 以及而 右杆 21上的弹簧 216和弹簧 218此时处于压缩状态， 由于弹簧的緩冲作用， 使得避震减压装置 2与背板 10的相对位置是固定的， 也即振荡不会直接作 用到背板 10上， 因此可以有效的减轻背包负重对使用者身体所造成的伤害， 大大提高了背包的舒适性。
图 21-24示出了本发明实施例双向性避震减压背负系统的避震减压装置 2的另一结构。 与图 6-10所示避震减压装置 2结构的相比， 图 21-24所示的 结构在左杆 20和右杆 21之间增加了中杆 40, 中杆 40上下分别通过弹性部 件 46、 47 (具体实现时为弹簧）与横杆 220、 221连接， 这样为在背袋 3重 载情况下， 本发明实施例双向性避震减压背负系统依然保持优异的避震减压 功能， 提供了保障。
具体先请参照图 21、 22所示， 支撑架 42两端分别固定在左杆 20和右 杆 21上， 并且与横杆 220、 221平行， 其上设置有旋转开关。 旋转开关包括 旋钮 41和旋转支撑杆 44, 旋转旋钮 41 , 旋转支撑杆 44可绕同一转轴旋转。
再请参照图 23所示， 旋转旋钮 41 , 使旋转支撑杆 44旋转至水平位置， 此时避震减压装置 2处于加压状态， 即左杆上的弹性部件 206、 207, 右杆上 的弹性部件 216、 217,以及中杆 40两端的弹性部件 46、 47均处于工作状态， 其中弹性部件 206、 46和 216执行同样的操作， 弹性部件 207、 47和 217执 行同样的操作。 以图 19所示的应用场景为例， 左杆 20上的弹簧 205和弹簧 207, 以及右杆 21上的弹簧 215和弹簧 217处于压缩状态， 而左杆 20上的 弹簧 206和弹簧 208,以及右杆 21上的弹簧 216和弹簧 218此时处于伸长状 态， 中杆 40上部的弹簧 46处于伸长状态， 而下部的弹簧 47处于压缩状态， 中杆 40将随弹簧压缩或伸长而上下移动。 由于弹簧的緩冲作用， 使得避震 减压装置 2与背板 10的相对位置是固定的， 也即振荡不会直接作用到背板 10上， 因此可以有效的减轻背包负重对使用者身体所造成的伤害， 大大提高 了背包的舒适性。 并且由于增加了弹簧 46、 47, 增加了緩冲效果， 使得即使 在重载情况下，本发明实施例双向性避震减压背负系统依然保持优异的避震 减压功能。
如图 24所示， 旋转旋钮 41 , 使旋转支撑杆 44旋转至与支撑架成 45。 夹角位置。 此种情形下， 弹簧 46、 47处于自由状态。 当出现图 19或图 20 所示应用场景时， 左杆 20上的弹簧 206、 207, 右杆 21上的弹簧 216、 217 会压缩或伸长， 但弹簧 46、 47则不会受力， 中杆 40也将保持不动。 因此， 也就相当于只有左杆 20和右杆 21会起到緩冲作用，适用于非重载的应用场 景。
再如图 22所示， 旋转旋钮 41 , 使旋转支撑杆 44旋转至竖直位置， 此时 旋转支撑杆 44扣在横杆 220上，横杆 220和支撑架 42之间的相对距离固定， 避震减压装置上的弹性部件均不起作用， 背负系统相对稳定。
以上所揭露的仅为本发明较佳实施例而已， 当然不能以此来限定本发明 之权利范围， 因此依本发明权利要求所作的等同变化， 仍属本发明所涵盖的 范围。
