The invention relates to the technical field of automobile seat accessories, provides an angle adjusting device suitable for an automobile backrest, and solves the technical problem that in the prior art, an automobile seat backrest angle adjusting mechanism cannot meet the use requirement under the working condition of large torque. An angle adjusting device suitable for a vehicle backrest comprises a fixed disc and a movable disc rotating relative to the fixed disc, a driving block for receiving power input by a central spindle is arranged outside the central spindle, a containing gap is formed between the driving block and the central spindle, a locking wedge block and a lining are arranged in the containing gap, and the locking wedge block and the lining are arranged on the fixed disc. The lining is arranged outside the locking wedge block in a sleeved mode, a transition fluted disc is arranged outside the lining in a sleeved mode, and the movable disc is provided with a gear ring matched with the transition fluted disc. The eccentric amount between a traditional movable disc and a traditional fixed disc is counteracted in a transition gear structure mode, meanwhile, the double locking wedge blocks are adopted for locking the gear, and therefore the movable disc and the fixed disc can be locked in time while concentric movement is met, and the application requirement for high torque strength is met.
本发明涉及汽车座椅配件技术领域,提供的一种适用于车辆靠背的角度调节装置,解决了现有技术中汽车座椅靠背角度调节机构无法满足扭矩较大工况下使用需求的技术问题。一种适用于车辆靠背的角度调节装置,包括定盘和相对于所述定盘旋转的动盘,所述芯轴外设置有接收所述芯轴输入的动力的驱动块,所述驱动块与所述芯轴之间具有容纳间隙,所述容纳间隙内设置有锁止楔块以及衬套,所述衬套套设于所述锁止楔块外,所述衬套外套设有过渡齿盘,所述动盘具有与所述过渡齿盘配合的齿圈。采用过渡齿轮结构方式抵消传统动、定盘之间的偏心量,同时采用双锁止楔块对齿轮进行锁止,从而使动、定盘在满足同心运动的同时也能锁止及时,满足高扭矩强度应用要求。
