AI Technical Summary

Technical Problem

The existing seat turntable mechanism has side gaps and free gaps, and it is impossible to achieve gapless locking, resulting in shaking and noise when the seat rotates, reducing riding comfort, and limited locking strength, requiring an external locking mechanism, which is complex in structure and high cost.

Method used

The core part is used as the rotating joint, including the inner tooth plate, the outer tooth plate, the eccentric component and the gap removal component, forming a planetary gear transmission mechanism with a low tooth difference, eliminating the eccentric movement through the limiting member, achieving concentric rotation of the seat, and driving connection through the driving component to eliminate side gaps and free rotation gaps.

Benefits of technology

360° unlimited rotation is achieved, eliminating the side gap and free rotation gap of the seat turntable mechanism, improving riding comfort, enhancing locking strength, simplifying the structure and reducing costs.

Abstract

Disclosed is a seat turntable mechanism, comprising a movable disc (1) and a fixed plate (2) which are connected in an axially limited manner and can circumferentially rotate relative to each other, and further comprising a core member (3), a limiting member, and a driving component (4). The core member comprises an inner toothed plate (31) provided with an inner ring gear (a), an outer toothed plate (32) provided with an outer ring gear (b), an eccentric component, and a gap elimination component. The inner toothed plate and the outer toothed plate are meshed with each other, and an eccentric region is formed therebetween; the eccentric component is located in the eccentric region; the gap elimination component is used for eliminating gaps among components; the driving component and the eccentric component are transmittingly connected; the limiting member is used for limiting the rotation of the outer toothed plate, so that the outer toothed plate carries out a circular motion; the outer toothed plate drives the inner toothed plate to rotate; and the inner toothed plate and the movable disc are fixedly connected. The limiting member eliminates the eccentric motion of the core member, realizing gap-free locking. Also disclosed is a vehicle comprising the seat turntable mechanism.
