The hinge comprises a rotating piece, an elastic piece and a shell, and the rotating piece is connected to the elastic piece; the shell is provided with a first limiting surface and a second limiting surface which are distributed at an interval; the first rotating process of the rotating part in the preset direction at least comprises a first stage without damping force and a second stage with damping force; when the rotating piece is in the first stage, the elastic piece rotates between the first limiting surface and the second limiting surface along with the rotating piece; when the rotating piece is in the second stage, the elastic piece abuts against the first limiting face, the rotating piece rotates relative to the elastic piece so as to form a friction pair together with the elastic piece, and the friction pair generates damping force. The first stage is used for improving the smoothness when the handrail is turned downwards initially, the second stage is used for reducing the falling speed of the handrail, speed control over the falling process of the handrail is achieved, and the operation comfort is improved.

    本公开涉及一种铰链和扶手,铰链包括:转动件、弹性件和壳体,转动件连接于转动件;壳体具有间隔分布的第一限位面和第二限位面;转动件朝向预设方向的第一转动过程至少包括:未受到阻尼力的第一阶段和受到阻尼力的第二阶段;转动件处于第一阶段时,弹性件随转动件在第一限位面和第二限位面之间转动;转动件处于第二阶段时,弹性件与第一限位面抵接,转动件相对弹性件转动以与弹性件共同形成摩擦副,摩擦副产生阻尼力。以利用第一阶段提高扶手初始向下翻转时的顺畅性,并利用第二阶段降低扶手的下落速度,实现了对扶手下落过程的速度控制,提高了操作舒适性。
