The invention belongs to the technical field of vehicle seats, and particularly relates to a multi-connecting-rod structure, a transmission mechanism and a turnover seat.The multi-connecting-rod structure comprises a two-connecting-rod and a four-connecting-rod, and the two-connecting-rod comprises a driving rod and a driven rod hinged to the driving rod; the four-bar linkage comprises a lower connecting rod hinged to the driven rod and an upper connecting rod arranged above the lower connecting rod, the two ends of the lower connecting rod and the two ends of the upper connecting rod are hinged to the fixed rod and the movable rod respectively, the hinge point of the driven rod and the lower connecting rod is located at the 1/3 position of the lower connecting rod, and the rotating included angle between the driven rod and the driving rod is smaller than 180 degrees. According to the invention, the operation is simple, the reliability is high, the opening/closing motion trail of the seat surface is changed by setting the parameters of the multi-connecting-rod structure, and the phenomenon that the seat surface is scratched with the side wall in the overturning process of the seat surface is avoided; meanwhile, when the seat surface is closed, a small angle is formed between the seat surface and the seat framework, and the whole closing process is smooth.

    本发明属于车辆座椅技术领域,具体涉及一种多连杆结构、传动机构及翻转座椅,其中多连杆结构包括二连杆和四连杆,所述二连杆包括主动杆和铰接在主动杆上的从动杆,所述四连杆包括与从动杆铰接的下连杆以及设置于下连杆上方的上连杆,所述下连杆和上连杆的两端均分别铰接于固定杆和活动杆,所述从动杆与下连杆的铰接点位于下连杆的1/3处,且从动杆与主动杆之间的转动夹角小于180°。本发明操作简单,可靠性较高,通过设置多连杆结构参数,改变座椅椅面打开/关闭运动轨迹,避免座椅椅面翻转过程中,与侧墙刮蹭的现象;同时当座椅椅面关闭时,座椅椅面与座椅骨架之间形成较小的角度,整个关闭过程较为顺畅。
