[0040] 此外, 所述活动斜滑块 402及第二弹簧 405均设置于所述第三凹槽 418内, 其中 , 所述第二弹簧 405缠绕于所述活动斜滑块 402的表面, 所述活动斜滑块 402在所 述第二弹簧 405的作用下可以在垂直方向上下移动。 所述第一针阀 407的表面设 置多个滑槽 404, 所述滑槽 404与所述活动斜滑块 402配合。 当所述活动斜滑块 40 2的底部位于所述滑槽 404内, 所述活动斜滑块 402卡住所述第一针阀 407, 使得 所述第一针阀 407停止移动。 需要说明的是, 参见图 2, 当所述第一针阀 407水平 向左移动吋, 所述活动斜滑块 402向上凸起。 在其它实吋例中, 所述活动斜滑块 402、 滑槽 404、 第二弹簧 405及第三凹槽 418的作用在于: 当用户通过拉带 5拉动 所述第一针阀 407后, 防止第一针阀 407在第一弹簧的作用下向右回弹。 在其它 实施例中, 所述活动斜滑块 402、 滑槽 404、 第二弹簧 405及第三凹槽 418可以省 略。
[0041] 所述控制阀体 401的左侧设置有第一导气管 408及第二导气管 415, 其中, 第一 导气管 408与所述气体容器 7连接, 所述第二导气管 415与所述连接管 3连接。 所 述第一导气管 408及所述第二导气管 415均连接至所述第一凹槽 416。 所述第一导 气管 408及第二导气管 415还与所述第二凹槽 417。
[0042] 进一步地, 如图 5所示, 所述固定轴 409与所述第二针阀 414连接, 所述固定轴 4 09还与所述槽片 410连接, 所述电机传动键 412设置于所述电机 411上, 所述电机 传动键 412与所述槽片 410连接。 当所述电机 411转动吋, 所述电机传动键 412通 过所述电机传动键 412带动所述槽片 410向下或向上移动, 由于所述固定轴 409与 所述第二针阀 414连接, 所述槽片 410向下或向上移动会带动所述第二针阀 414上 下移动。 具体地说, 当所述电机 411逆吋针旋转吋, 所述槽片 410向下运动, 所 述槽片 410向下运动并带动所述第二针阀 414向下运动, 第二针阀 141与所述第二 凹槽 417的尖部脱离。 当所述电机 411顺吋针旋转吋, 所述槽片 410上下运动, 所 述槽片 410向上运动并带动所述第二针阀 414向上运动, 所述第二针阀 141与所述 第二凹槽 417的尖部贴合。 在本实施例中, 所述槽片 410为 U型槽片。
[0043] 所述第二针阀 414设置于所述第二凹槽 417内, 所述第二针阀 414在所述第二凹 槽 417内上下移动。 所述第二密封圈 413设置于所述第二凹槽 417内, 用于防止所 述第二凹槽 417漏气。
[0044] 所述气体容器 7中的压缩气体通过第一导气管 408输入至所述阀门 4, 并通过第 二导气管 415输入至连接管 3中, 之后由连接管 3将压缩气体输入至充气腰带 2中
[0045] 所述第一针阀 407与所述第一凹槽 416的顶部均为尖部结构, 所述第二针阀 414 与所述第二凹槽 417的顶部也均为尖部结构。
[0046] 如图 2所示, 当所述第一针阀 407的尖部与所述第一凹槽 416的尖部紧密贴合, 且所述第二针阀 414的尖部与所述第二凹槽 417的尖部也紧密贴合吋, 所述第一 导气管 408内的气体被所述第一针阀 407及所述第二针阀 414阻挡, 而不会流入至 第二导气管 415。
[0047] 如图 3所示, 当用户通过拉带 5拉拽所述第一针阀 407吋, 所述第一针阀 407向左 移动。 当所述第一针阀 407的尖部与所述第一凹槽 416的尖部脱离, 所述第一导 气管 408内的气体通过第一凹槽 416流入至第二导气管 415。
[0048] 如图 4所示, 当用户通过所述电机 411拉动所述槽片 410并带动所述第二针阀 414 向下移动, 所述第二针阀 414的尖部与所述第二凹槽 417脱离, 所述第一导气管 4 08内的气体通过第二凹槽 417流入至第二导气管 415。
[0049] 进一步地, 所述电机 411还与所述控制器 70电连接, 所述控制器 70控制所述电 机 411的转动。 所述控制器 70还与所述重力传感器 8电连接。 所述重力传感器 8用 于检测所述老人摔倒自动防护装置的加速度, 当所述老人摔倒自动防护装置的 加速度为重力加速度吋, 表明用户处于跌倒下落状态, 所述控制器 70控制所述 电机 411转动, 所述电机 411拉动所述槽片 410并带动所述第二针阀 414向下移动 , 所述第二针阀 414的尖部与所述第二凹槽 417脱离, 所述第一导气管 408内的气 体通过第二凹槽 417流入至第二导气管 415, 所述气体进入充气腰带 2, 使得所述 充气腰带 2鼓起, 缓冲摔倒的冲击力, 减少摔倒导致的伤害。
[0050] 所述老人摔倒自动防护装置的工作原理如下: 所述老人摔倒自动防护装置佩戴 于用户防护部位 (例如, 膝盖部、 腰部、 手关节部等) , 并将拉带 5绑定于用户 的手部, 当用户身体瞬间发生重度倾斜 (例如, 摔倒) 吋, 所述重力传感器 8检 测出所述老人摔倒自动防护装置的加速度为重力加速度, 控制器 70控制所述阀 门 4中的电机 411逆吋针旋转并带动所述槽片 410向下运动, 所述槽片 410向下运 动并带动所述第二针阀 414向下运动, 第二针阀 141与所述第二凹槽 417的尖部脱 离, 气体容器 7中的气体从第一导气管 408进入第二导气管 415。 同吋, 由于拉带 5绑定于用户的手部, 当用户摔倒吋, 手臂张幵拉带 5拉动第一针阀 407向左移动 , 第一针阀 407与第一凹槽 416的尖部脱离, 气体容器 7中的气体从第一导气管 40 8进入第二导气管 415。 第二导气管 415中的气体通过连接管 3快速向充气腰带 2充 气, 使充气腰带 2迅速膨胀, 使用户倒地吋缓冲用户摔倒的冲击力, 减少用户的 伤害。 使用完成后, 用户通过放气阀 1给充气腰带 2放气。
[0051] 以上仅为本发明的优选实施例, 并非因此限制本发明的专利范围, 凡是利用本 发明说明书及附图内容所作的等效结构或等效流程变换, 或直接或间接运用在 其他相关的技术领域, 均同理包括在本发明的专利保护范围内。
