The invention discloses a roller type armrest stepless adjusting mechanism and an automobile seat armrest. An assembly cavity is formed in the shell assembly. A locking collision part and an unlockingcollision part are arranged on the inner wall of the assembly cavity; a rotating shaft is rotationally mounted on the shell assembly; the rotating shaft is fixedly sleeved with a driving plate; a roller adapting groove is formed in the outer side of the driving plate; a roller is arranged between the roller adapting groove and the inner wall of the assembly cavity; when the roller collides with the locking collision part, the two sides of the roller make contact with the groove bottom of the roller adapting groove and the inner wall of the assembly cavity respectively, the driving plate is constructed to be of a one-way movement structure relative to the shell assembly, after the roller collides with the unlocking collision part, the roller is separated from the groove bottom of the roller adapting groove, and the driving plate can freely rotate within the stroke limited by the unlocking collision part and the locking collision part. The roller type armrest stepless adjusting mechanism and the automobile seat armrest have the advantages that the structural design is ingenious, the product is easy to realize, an armrest is convenient to adjust, the armrest can be kept at any heightposition, and the comfort is achieved.
本发明公开了一种滚柱式扶手无级调节机构及汽车座椅扶手,壳体总成内设有装配腔,装配腔的内壁上设有锁定碰撞部与解锁碰撞部,壳体总成上转动安装有转轴,转轴上固套有驱动板,驱动板的外侧设有滚柱适配槽,滚柱适配槽与装配腔的内壁之间设有滚柱,当滚柱与锁定碰撞部发生碰撞后,滚柱的两侧分别与滚柱适配槽的槽底和装配腔的内壁接触,驱动板相对于壳体总成被构造成单向运动结构,当滚柱与解锁碰撞部发生碰撞后,滚柱与滚柱适配槽的槽底分离,驱动板能够在解锁碰撞部与锁定碰撞部限定的行程内自由转动。本发明的有益效果是:结构设计巧妙,产品易于实现,扶手调节便利,能够使扶手保持在任意高度位置,舒适性好。
