According to the transmission damping structure and the armrest table board, the transmission damping structure slides upwards along with a sliding piece, a triggering piece triggers a starting piece and a tooth piece to slide upwards for the first time so as to drive a transmission gear set meshed with the triggering piece to rotate forwards, so that a rotating piece is driven to rotate forwards relative to the sliding piece, and then slides downwards along with the sliding piece; the triggering piece triggers the starting piece again, and the gear piece slides downwards to drive the transmission gear set to rotate reversely, so that the rotating piece is driven to rotate reversely; when the automatic unfolding device is applied to the armrest and the table plate assembly, the table plate assembly slides upwards along the sliding rails till the table plate body extends out of the upper portion of the armrest, then the table plate body is pushed to rotate to the horizontal state along with upward sliding of the sliding plate, automatic unfolding of the table plate body is achieved, and the overall structure is simple; and the damping assembly limits the sliding speed of the tooth bar through mutual restriction among the first elastic piece, the second elastic piece and the damping piece, the rotating speed of the table board body can be controlled, and instant opening or closing of the table board is avoided.
本申请公开了传动阻尼结构和扶手桌板,传动阻尼结构随着滑动件向上滑动,触发件首次触发启动件,齿条件向上滑动从而带动与之啮合的传动齿轮组正向转动,从而驱动转动件相对于滑动件正向转动,之后随着滑动件向下滑动,触发件再次触发启动件,齿条件向下滑动从而带动传动齿轮组反向转动,从而驱动转动件反向转动;将其应用于扶手和桌板组件中,桌板组件先沿滑轨向上滑动至桌板本体伸出扶手上方,之后随着滑动板继续向上滑动推动桌板本体转动至水平状态,实现了桌板本体的自动展开,整体结构简单;并且阻尼组件通过第一弹性件、第二弹性件和阻尼件之间的相互制约,限制了齿条件的滑动速度,能够控制桌板本体的转动速率,避免桌板瞬时打开或关闭。
