The invention provides a seat concentric angle adjuster or rotary joint which comprises a core angle adjuster, an outer gear ring and an output gear sleeve; the core angle adjuster comprises a fixed gear ring and a planetary gear, the outer gear ring is concentrically welded and matched with an eccentric gear of the core angle adjuster, and the planetary gear of the core angle adjuster is in eccentric transmission with the inner fixed gear ring. Similarly, the outer gear ring and the inner teeth of the output gear sleeve eccentrically rotate relatively; the concentric shaft sleeve is concentrically matched with the output gear sleeve, the outer gear ring is welded and assembled at the eccentric planetary gear shaft sleeve structure of the core angle adjuster, the fixed gear ring is arranged in the core angle adjuster, and an eccentric planetary gear in the core angle adjuster and the output gear sleeve of the outer gear ring form coaxial eccentric planetary gear transmission; the output gear sleeve and the outer gear ring form the output stage of the planetary gear, the output gear sleeve is matched with the concentric shaft sleeve so that the output gear sleeve can generate concentric movement relative to the fixed gear ring in the core angle adjuster, eccentricity of the concentric movement is eliminated, transmission is more stable, and the user experience and the comfort are greatly improved.

    本发明提供一种座椅同心调角器或旋转关节,包括:核心调角器、外齿圈、输出齿套,所述核心调角器包括:固定齿圈、行星齿轮,外齿圈与核心调角器偏心齿轮同心焊接匹配,核心调角器的行星齿轮与内部固定齿圈偏心传动,同样外齿圈与输出齿套内齿相对偏心转动;同心轴套与输出齿套同心匹配,外齿圈焊接装配于核心调角器偏心行星齿轮轴套结构处,核心调角器内部有固定齿圈,核心调角器内部偏心行星齿轮与外齿圈输出齿套形成同轴偏心行星齿轮传动,输出齿套与外齿圈形成行星齿轮的输出级,输出齿套在同心轴套的匹配中使输出齿套产生相对于核心调角器内部固定齿圈的同心运动,这种同心运动偏心得到消除,传动更加稳定,用户体验舒适性有极大提升。
