[0022] 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。 [0023] 实施例一:
[0024] 请参阅图 1至图 5, 本发明实施例提供的一种穿戴式辅助搬运装置 100, 包括两 个夹持器 50、 两个拉力机构 30、 导力架 10和绑带 70; 绑带 70与导力架 10相连, 用于将导力架 10固定于人体上; 导力架 10包括两个支杆 11和承力带 13, 两个支 杆 11的上端分别延伸至人体两肩前端, 两个拉力机构 30分别与两个支杆 11相连 ; 承力带 13用于配合支撑于人体髋部, 从而在导力架 10受力吋, 可以将该力传 导到人体髋部。 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。 两个拉力机 构 30分别与两个夹持器 50相连, 用于向上拉动相应夹持器 50, 从而在夹持器 50 夹持并支撑重物吋, 可以向上拉动重物, 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 30的承受的负载力, 传递至相应的支杆 11, 再传导 至人体髋部, 从而使重物的大部分负载被人体髋部承受, 以减轻腰部负载, 从 而保护人员腰部、 脊柱, 减轻人的肌肉劳损和人体疲劳。
[0025] 该穿戴式辅助搬运装置 100在使用吋, 通过绑带 70将导力架 10固定在人体上, 导力架 10的承力带 13支撑在人体髋部; 两个支杆 11的延伸至人两肩的前端, 两 个拉力机构 30分别连接两个支杆 11与两个夹持器 50; 两个夹持器 50佩戴在人的 双手上; 在搬运重物吋, 两个夹持器 50支撑住重物, 防止手部受伤; 而在人搬 运重物起身吋, 会带动导力架 10向上移动, 从而导力架 10的两个支杆 11向上拉 动两个拉力机构 30, 并使两个拉力机构 30向上拉动两个夹持器 50, 从而减轻手 臂的负载。 而重物的大部分负载经拉力机构 30传送至支杆 11。 这样, 该重物的 负载力没有从人体脊柱中传递, 而是通过导力架 10建立了一个力传递"旁路", 传 递到人体髋部。 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, 重力会对导力架 10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。 使用该穿戴式辅助搬运装置 100吋, 该倾翻 力矩的一部分会由人体髋部产生的力矩来克服, 减轻腰部受力。
[0026] 通过设置两个夹持器 50、 两个拉力机构 30、 绑带 70和导力架 10; 使用吋, 通过 绑带 70将导力架 10安装在人体上, 导力架 10的承力带 13支撑在人体髋部, 导力 架 10的两个支杆 11的上端分别延伸至人两肩的前端, 两个拉力机构 30分别连接 两个支杆 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 30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 30将对夹持器 50的拉力传导至导力架 10的支杆 11, 而 使导力架 10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、 脊柱, 减轻人的肌肉劳损和人体疲劳。 。
[0027] 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, 从而在将导力架 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。
