The invention relates to a concentric angle adjusting mechanism which is characterized in that a cam shaft is arranged in a through hole of a gear, a first gear ring and a second gear ring are mutually buckled to define a containing cavity for the gear, and a hoop is buckled on the first gear ring and the second gear ring and fixedly connected with the first gear ring to define a mounting cavity; the wedge-shaped block and the disc-shaped spring are contained in the installation cavity to eliminate the lateral gap, a groove is formed in the inner wall of the first gear ring, an inclined face is arranged on the outer wall of the second gear ring, the inclined face and the groove are matched to form a limiting groove to assemble the wedge-shaped block, and the disc-shaped spring is supported on the hoop and the wedge-shaped block. According to the concentric angle adjusting mechanism, the wedge-shaped block and the disc spring, a damping system in modular design is formed, so that the concentric angle adjusting mechanism with damping is provided, the lateral gap is improved, and the damping force in the rotating direction is provided, and therefore the provided seat backrest small armrest has the comfortable hand feeling of stable movement in the rotating adjusting process; the zero-gravity seat armrest is particularly suitable for self-adaptive and stepless-adjustment zero-gravity seat armrest scenes.

    本发明涉及一种同心角度调节机构,凸轮轴设置于齿轮的通孔内,第一齿圈和第二齿圈相互扣合围合出用于齿轮的容置腔,抱箍扣合在第一齿圈和第二齿圈上并与第一齿圈固定连接以围合出安装腔,楔形块和碟形簧容置于安装腔内以消除侧向间隙,第一齿圈的内壁具有凹槽,第二齿圈的外壁具有斜面,斜面与凹槽配合形成限位槽以装配楔形块,碟形簧支撑在抱箍和楔形块上。根据本发明的同心角度调节机构,楔形块和碟形簧形成模块化设计的阻尼系统,以提供可带阻尼的同心角度调节机构,改善侧向间隙,提供旋转方向的阻尼力,由此提供的座椅靠背小扶手在旋转调节过程中,具有平稳运动的舒适手感,尤其适用自适应、无级调节的零重力座椅扶手场景。
