本发明的实施方式 [0017] 为了使本发明的目的、 技术方案及优点更加清楚明白， 以下结合附图及实施例 ， 对本发明进行进一步详细说明。 应当理解， 此处所描述的具体实施例仅仅用 以解释本发明， 并不用于限定本发明。
[0018] 需要说明的是， 当元件被称为 "固定于"或"设置于"另一个元件， 它可以直接在 另一个元件上或者可能同吋存在居中元件。 当一个元件被称为"连接于 "另一个元 件， 它可以是直接连接到另一个元件或者可能同吋存在居中元件。
[0019] 还需要说明的是， 本实施例中的左、 右、 上、 下等方位用语， 仅是互为相对概 念或是以产品的正常使用状态为参考的， 而不应该认为是具有限制性的。
[0020] 实施例一：
[0021] 请参阅图 1至图 6， 本发明实施例提供的一种双幵穿戴式辅助搬运装置 100， 包 括两个夹持器 50、 两个拉力机构、 背架 10和绑带 （图中未示出） ； 绑带与背架 1 0相连， 用于将背架 10固定于人体上； 夹持器 50用于夹持并支撑待搬运物体， 在 使用吋， 一般佩戴于人的手部， 以方便搬运， 避免重物直接压在手上， 防止手 部受伤。
[0022] 请参阅图 1和图 2， 背架包括承力带 13、 两个肩杆 11和支架 20， 承力带 13用于配 合支撑于人体髋部， 从而在背架 10受力吋， 可以将该力传导到人体髋部。 支架 2 0的下端与承力带 13铰接， 在使用吋， 支架 20设在人体后背位置， 两个肩杆 11分 别置于人体两肩上方。 支架 20的上端枢接有两个可左右摆动的转动杆 205， 两个 转动杆 205的上端延伸至人体肩部后侧； 两个肩杆 11分别由人体后背经两肩上方 延伸至两肩前端， 两个肩杆 11的后端分别与两个转动杆 205相连。 设置位于人体 后背位置的支架 20， 在传导负载力吋， 可以使重物对人体向前的倾翻力矩的一 部分由人体背部的接触力克服， 进一步减轻腰部受力， 同吋通过支架 20的矫正 作用， 在搬运过程中， 可以阻止脊柱弯曲， 使劳动者在人力搬运过程中保持脊 柱姿势正确， 以此保证劳动者的腰背的健康安全， 减少职业伤病的发生。 支架 2 0的下端与承力带 13铰接， 便支架 20可以相对于承力带 13上下摆动。 从而在穿戴 后， 人在下蹲拾取重物过程中腰部可以适当的弯曲， 以提高使用的舒适性。 而 在搬运重物吋， 绳带拉动肩杆 11， 带动支架 20向前移动， 而抵住人的后背， 以 起力传递使用。 各肩杆 11可以在支架 20左右摆动。 则在人在下蹲吋， 或穿戴吋 ， 可以将两个肩杆 11分别向人的两侧转动， 以方便穿戴及下蹲。
[0023] 通过设置两个夹持器 50、 两个拉力机构、 绑带和背架 10; 使用吋， 通过绑带将 背架 10安装在人体上， 背架 10的承力带 13支撑在人体髋部， 背架 10的两个肩杆 1 1分别延伸至人两肩的前端， 两个拉力机构分别连接两个肩杆 11与两个夹持器 50 ， 从而在搬运重物吋， 可以使用夹持器 50来夹持重物， 并向经拉力机构上拉动 重物， 以减轻手臂的负载， 减轻因反复搬运造成的手臂疲劳； 而拉力机构将对 夹持器 50的拉力传导至背架 10的肩杆 11， 再经支架 20、 承力带 13将该负载拉力 传导至人体的髋体， 减轻人体腰背部分受力， 从而保护人员腰部。 而两个转动 杆 205在支架 20上可左右摆动， 进而可以带动两个肩杆 11左右摆动， 以方便穿戴 ； 支架 20的下端与承力带 13铰接， 从而在穿戴后， 人在下蹲拾取重物过程中腰 部可以适当的弯曲， 以提高使用的舒适性。
[0024] 该背架 10在使用吋， 可以通过绳带等将肩杆 11的前端与负载重物相连， 从而人 搬运重物起身吋， 会带动背架 10向上移动， 从而背架 10的两个肩杆 11向上拉动 重物， 从而减轻手臂的负载。 而重物的大部分负载传送至肩杆 11。 这样， 该重 物的负载力没有从人体脊柱中传递， 而是通过背架 10建立了一个力传递"旁路"， 经两肩杆 11、 支架 20、 承力带 13传递至人体的髋部， 减轻人体腰背部分受力， 从而保护人员腰部、 脊柱， 减轻人的肌肉劳损和人体疲劳。 另外， 由于重物悬 挂于人体前方， 其重力作用线与人体支撑点之间存在水平距离， 重力会对背架 1 0产生一个倾翻力矩， 而且这个力矩在抬放重物吋由于身体前倾会显著增大。 使 用该背架 10吋， 该倾翻力矩的一部分由人体背部的接触力克服、 一部分会由人 体髋部产生的力矩来克服， 减轻腰部受力。
[0025] 进一步地， 本实施例中， 承力带 13为用于配合绑定于人体髋部的腰带。 将承力 带 13设为腰带结构， 既可以方便安装固定在人的髋部， 同吋可以起到承力支撑 作用。 在其它实施例中， 承力带 13也可以为与配合叉于人体两侧髋部的两个叉 架结构， 从而在将背架 10安装在人体上吋， 两个叉架叉在人的髋部。 在还有一 些实施例中， 承力带 13也可以为 U型架结构， 在使用中吋， 直接架在人体的髋部
[0026] 进一步地， 本实施例中， 承力带 13为钢带结构， 承力带 13的两端安装的挂扣结 构， 以便在安装吋， 可以将承力带 13的两端相互扣合连接。 在还有一些实施例 中， 腰带材质可以是布质、 橡胶、 钢带等柔性结构。
[0027] 进一步地， 承力带 13呈倒锥型结构， 以便承受竖直方向的载荷， 提高穿戴的舒 适性。
[0028] 进一步地， 支架 20还包括上连接块 201、 下连接块 202和并排设置的两根连杆 20 3， 上连接块 201将两根连杆 203的上端相连， 下连接块 202将两根连杆 203的下端 相连， 两个转动杆 205分别与上连接块 201相连。 该结构的支架 20结构简单加工 方便。
[0029] 进一步地， 各连接杆 203可以为伸缩杆， 以便调节支架 20的长度。
[0030] 进一步地， 支架 20还包括用于配合贴合人体脊柱的弹性抵持板 204， 弹性抵持 板 204的的两端分别与上连接块 201和下连接块 202相连。 弹性抵持板 204中部拱 起， 以便与人体脊柱贴合吋能适应脊柱的形状变形， 使脊柱均匀受力。
[0031] 进一步地， 两根连杆 203分别与两根转动杆 205相连， 且各连杆 203与相应的转 动杆 205是一体成型。 该结构可以增加支架 20的强度， 同吋方便加工制作。
[0032] 进一步地， 支架 20的下端的两侧分别连接有支杆 26， 两个支杆 26分别与承力带 13的两侧铰接。 从而通过两个支杆 26将支架 20的下端与承力带 13铰接。 该结构 可以使支架 20承受的负载力， 直接作用在承力带 13的两侧， 使搬运更轻松。
[0033] 更进一步地， 该背架 10还包括若干分别将各支杆 26靠近支架 20的一端与承力带 13相连的拉簧 27。 由于拉簧 27的作用， 在人体身体前倾或弯腰拾取重物吋， 背 架 10对人体腰部提供一个补偿力矩， 补偿人体自身重力对腰部的负载， 使人体 感觉轻松。
[0034] 进一步地， 各肩杆 11呈管状结构， 该背架 10还包括分别穿过两个肩杆 11与承力 带 13相连的两根拉绳 28， 各拉绳 28与承力带 13上于支架 20下端对应的位置相连 。 当拉绳 28与重物负载关联， 当人抬起重物吋拉绳 28在背架 10与承力带 13之间 形成一个扭矩， 帮助人体脊柱恢复竖直状态， 起身后拉绳 28的力作用使支架 20 被约束， 支架 20与承力带 13之间的旋转副不会有运动， 这样使得重物产生的倾 翻力矩会传递到承力带 13上， 而不会作用到人体脊柱上。
[0035] 进一步地， 本实施例中， 两根支杆 26分别与两根连杆 203的下端相连， 以便将 支架 20的下端通过支杆 26枢接在承力带 13上。
[0036] 进一步地， 本实施例中， 各转动杆 205呈 L型， 以方便加工， 及在上连接块 201 上转动。 在其它实施例中， 各转动杆 205也可以呈其它形状。
[0037] 请参阅图 2、 图 3和图 5， 进一步地， 各拉力机构包括两端分别连接拉绳 28与相 应夹持器 50的绳带 31。 使用绳带 31作为拉力机构， 可以方便弯曲移动， 从而方 便手臂带动夹持器 50移动。 在其它实施例中， 拉力机构也可以使用拉杆结构， 如将拉杆的上端与肩杆 11通过铰链相连， 而拉杆的下端与夹持器 50相连， 从而 也可以起到力传送的作用。
[0038] 进一步地， 各拉力机构还包括收卷锁定器 32， 收卷锁定器 32安装于相应的肩杆 11上。 收卷锁定器 32用于收卷绳带 31并于绳带 31受力吋锁定该绳带 31。 设置收 卷锁定器 32， 在绳带 31不受力吋， 可以使绳带 31自由伸长与收缩， 以方便手臂 活动； 而在夹持器 50固定住重物， 向上拉动重物吋， 收卷锁定器 32可以锁定住 绳带 31， 以使绳带 31可以受力负载的重力。 本实施例中， 拉绳 28与收卷锁定器 3 2相连。 更进一步地， 绳带 31与拉绳 28可以使用同一根绳索。
[0039] 具体地， 收卷锁定器 32包括支撑盒 321、 枢接于支撑盒 321中的卷筒 321、 带动 卷筒 321卷绕绳带 31的卷簧 323、 与卷筒 321相连的棘轮 324、 用于锁定棘轮 324的 棘爪 325和带动棘爪 325解锁棘轮 324的扭簧 326， 棘爪 325枢接于支撑盒 321中， 绳带 31的一端与卷筒 321相连， 绳带 31的另一端绕过夹持器 50与棘爪 325相连。 当绳带 31不受力吋， 扭簧 326推动棘爪 325离幵棘轮 324， 从而使棘轮 324与卷筒 3 21可以转动， 则手臂拉动吋， 可以将绳带 31从卷筒 321上拉出， 使绳带 31伸长； 而手臂向肩杆 11方向移动吋， 卷簧 323带动卷筒 321转动， 以收卷绳带 31。 当绳 带 31拉动重物吋， 将绳带 31的另一端拉紧， 则带动棘爪 325锁定棘轮 324， 从而 防止卷筒 321转动， 以使绳带 31可以承受负载。
[0040] 进一步地， 支撑盒 321上安装有减磨块 327， 绳带 31的另一端穿过减磨块 327与 棘爪 325相连。 设置减磨块 327， 可以减少对绳带 31的磨损。
[0041] 请一并参阅图 5和图 6， 进一步地， 各拉力机构还包括用于将绳带 31锁定以防止 该绳带 31收于卷筒 321上的锁线器 33， 锁线器 33安装于相应夹持器 50上。 设置锁 线器 33， 在使用吋， 可以通过锁线器 33锁定住绳带 31， 以更好的防止绳带 31伸 缩。 当然在其它实施例中， 当搬运重物吋， 可以压住或钩住绳带 31的另一端， 以拉动绳带 31的另一端， 进而拉动棘爪 325。
[0042] 进一步地， 锁线器 33包括支撑块 331、 转轴 332和挡块 333， 转轴 332安装在支撑 块 331上， 挡块 333固定在支撑块 331上， 且挡块 333设置在支撑块 331的侧边， 绳 带 31绕过转轴 332， 并且绳带 31的一端位于挡块 333与转轴 332之间。 这样当调节 支撑块 331位置吋， 可以使挡块 333顶压住绳带 31的另一端， 以将绳带 31锁定住 。 而当绳带 31与挡块 333分幵吋， 可以在转轴 332上自由移动， 进而使卷筒 321上 的绳带 31可以自由伸缩。 支撑块 331与夹持器 50相连。 在其它实施例中， 锁线器 33也可以为夹子结构， 在承重吋， 可以夹住绳带 31， 以将绳带 31锁定住。
[0043] 进一步地， 支撑块 331上还安装有连接块 334， 连接块 334用于与夹持器 50相连
[0044] 请参阅图 1和图 4， 进一步地， 各夹持器 50包括用于套于手上的手套 50， 手套 50 上对应于各手指的位置连接有韧带 52， 韧带 52与拉力机构相连， 手套 50上对应 于各指腹及掌心位置设有硬化块 53。 使用手套 50， 在手套 50的各手指上设置韧 带 52， 在受力吋， 韧带 52可以拉动手套 50， 使手套各手指弯曲， 而指腹及掌心 上设有硬化块 53， 可以方便手指扣住重物。 在其它实施例中， 夹持器 50也可以 为平板结构， 以便支撑重物。
[0045] 进一步地， 手套 50的各手指背面对应的位置配合设有定位套 55， 韧带 52穿过定 位套 55， 以便韧带 52可以拉动手套 50， 使手套各手指弯曲。
[0046] 进一步地， 手套 50上对应于掌心位置设有安装带 54。 在手套 50上设置安装带 54 ， 以便安装锁线器 33、 夹子等结构。 进一步地， 安装带 54可以为束紧带， 以便 安装锁线器 33。
[0047] 具体地， 本实施例中， 韧带 52与锁线器 33的连接块 334相连， 使绳带 31绕过锁 线器 33的转轴 332， 并使绳带 31的远离挡块 333的一端 311与收卷锁定器 32中的卷 筒 322相连； 使绳带 31的靠近挡块 333的一端 312与收卷锁定器 32中的棘爪 325相 连。 这样， 夹持器 50承载负载吋， 调节锁线器 33的位置， 使挡块 333抵住绳带 31 的另一端 312， 并且绳带 31的一端 311朝向挡块 333移动， 并将绳带 31的另一端 31 2抵压在挡块 333上， 以将绳带 31的另一端 312锁定； 则在绳带 31的另一端 312拉 动收卷锁定器 32中的棘爪 325， 使棘爪 325锁定棘轮 324， 从而防止卷筒 322转动 ； 使绳带 31张紧， 以承受负载。 当夹持器 50负载卸掉后， 绳带 31放松， 扭簧 326 推动棘爪 325离幵棘轮 324， 从而使棘轮 324与卷筒 322可以转动； 调节锁线器 33 的位置， 使绳带 31的两端远离挡块 333移动， 从而将绳带 31的另一端 312解锁， 则手臂拉动吋， 可以将绳带 31从卷筒 322上拉出， 使绳带 31伸长； 而手臂向肩杆 11方向移动吋， 卷簧 323带动卷筒 322转动， 以收卷绳带 31。
[0048] 进一步地， 绑带为背带结构， 以方便将背架 10背在人身上。
[0049] 实施例二：
[0050] 请参阅图 7和图 8， 本实施例的双幵穿戴式辅助搬运装置 100与实施例一的双幵 穿戴式辅助搬运装置区别为：
[0051] 本实施例中， 各肩杆 11可向上摆动铰接在转动杆 205上。 该背架 10还包括两个 支撑杆 15， 两个支撑杆 15的上端分别与两个肩杆 11的中部铰接， 两个支撑杆 15 的下端分别与承力带 13的两侧铰接。 在受力吋， 可以通过两个支撑杆 15来承受 与传递各肩杆 11承受的负载力， 从而可以减轻人背部的受力， 并且还可以减轻 负载力对支架 20的力矩， 使得搬运更为轻松。 该结构中， 支架 20与承力带 13之 间有旋转自由度， 在未加负载吋可实现小幅度弯腰。 当有负载吋， 由于杠杆作 用， 支架 20会有一个恢复竖直状态的力矩， 帮助起身。 当负重行走搬运吋， 负 载力和力矩会通过支架 20和支撑杆 15传递到承力带 13上， 减轻人体背部受到的 压力。
[0052] 进一步地， 各支撑杆 15的下端通过球铰 155与承力带 13相连， 以便支撑杆 15相 对于承力带 13可以更为灵活地转动。
[0053] 进一步地， 各支撑杆 15的上部设有供人手肩穿过的连接环 156。 设置连接环 156
， 可以更好的方便使用者穿戴， 提高使用的舒适性。
[0054] 进一步地， 本实施例中， 支架 20的下端直接与承力带 13铰接。
[0055] 本实施例的双幵穿戴式辅助搬运装置 100的其它结构与实施例一的双幵穿戴式 辅助搬运装置的其它结构相同， 在此不再赘述。
[0056] 实施例三：
[0057] 请参阅图 9和图 10， 本实施例的双幵穿戴式辅助搬运装置 100与实施例一的双幵 穿戴式辅助搬运装置区别为：
