The invention provides a seat turntable mechanism which comprises a fixed chassis and a movable turntable which are rotatably connected, a power mechanism and a locking mechanism are arranged between the fixed chassis and the movable turntable, the power mechanism comprises a power fluted disc and an operation motor fixed on the fixed chassis, and the power fluted disc is an annular fluted disc with teeth inside and outside; the power fluted disc is coaxially fixed on the movable rotating disc, a driving gear is arranged on an output shaft of the operation motor, and the driving gear is meshed with inner teeth of the power fluted disc; the locking mechanism comprises a locking mechanism assembly and a locking motor fixed to the fixed chassis, teeth matched with the locking mechanism assembly are arranged on the side, close to the power fluted disc, of the locking mechanism assembly, and the locking mechanism assembly is driven by the locking motor to complete tooth alignment with the power fluted disc firstly and then is meshed with outer teeth of the power fluted disc to achieve locking of the movable rotary disc. Full-stroke stepless locking can be achieved, and the problem that a locking tooth block and a power fluted disc are inaccurate in alignment and cannot be meshed is solved.
本发明提出了一种座椅转盘机构,包括转动连接的固定底盘和活动转盘,固定底盘和活动转盘之间设有动力机构和锁止机构,动力机构包括动力齿盘和固定于固定底盘上的运行电机,动力齿盘为内外均设有齿牙的环形齿盘,动力齿盘同轴固定于活动转盘上,运行电机的输出轴上设有驱动齿轮,驱动齿轮与动力齿盘的内齿啮合;锁止机构包括锁止机构组件和固定于固定底盘上的锁止电机,锁止机构组件靠近动力齿盘的一侧设置有与其匹配的齿牙,锁止机构组件受锁止电机驱动能先与动力齿盘完成对齿,再与动力齿盘的外齿啮合实现活动转盘的锁止。本发明能实现全行程无级锁止,且解决了锁止齿块与动力齿盘对位不准无法啮合的问题。
