The invention discloses a table plate connecting rod mechanism and a table plate assembly using a forward leaning posture as an initial design position, the table plate connecting rod mechanism comprises a left connecting rod mechanism and a right connecting rod mechanism, the left connecting rod mechanism and the right connecting rod mechanism comprise connecting rod supports, upper connecting rods and lower connecting rods, the connecting rod supports are fixedly connected with a chair back framework, and one side, facing the lower connecting rods, of each upper connecting rod is provided with a concave avoiding structure; the table plate assembly comprises a table plate framework and a table plate angle adjusting mechanism; the table plate framework is rotationally connected with the upper connecting rod through a shaft pin; the table plate angle adjusting mechanism comprises a rotating shaft and an angle adjuster; the angle adjuster can be locked or unlocked with the rotating shaft at multi-angle positions, the rotating shaft is arranged below the upper connecting rod, and the two ends of the rotating shaft are rotationally connected with the lower connecting rod. According to the connecting rod mechanism, the forward leaning posture of the seat backrest serves as the initial design position, when the connecting rod mechanism is matched with a table plate angle adjusting mechanism, table plate angle leveling within the range of most angles of forward leaning and backward leaning of the seat backrest can be achieved, and the applicability of a table plate is guaranteed.

    本发明公开了一种用前倾姿态作为初始设计位置的桌板连杆机构、桌板总成,桌板连杆机构包括左、右连杆机构,左、右连杆机构包括连杆支架、上连杆与下连杆,连杆支架与椅背骨架固连,上连杆朝向下连杆的一侧设有内凹的避让结构;桌板总成包括桌板骨架、桌板调角机构;桌板骨架与上连杆通过轴销实现转动连接;桌板调角机构包括转动轴、调角器;调角器能够在多角度位置与转动轴锁止或解锁,转动轴设置在上连杆的下方,两端分别与下连杆转动连接。该连杆机构以座椅靠背的前倾姿态作为初始设计位置,当配合桌板调角机构时,能够实现椅背从前倾~后仰大部分角度范围内的桌板角度找平,保证桌板的适用性。
