The invention provides an electric length-adjustable front connecting rod assembly and an automobile seat framework comprising the front connecting rod assembly, and belongs to the technical field of automobile seat frameworks. The front connecting rod assembly comprises a sliding rail front connecting bracket, a sliding rail rear connecting bracket and a sliding rail rear connecting bracket, wherein the sliding rail front connecting bracket is arranged on a sliding rail below an automobile seat framework; the toothed plate guide bracket is fixedly connected to the sliding rail front connecting bracket, and one end, far away from the sliding rail front connecting bracket, of the toothed plate guide bracket is connected with a cushion framework frame of the automobile seat framework; the toothed plate is in sliding connection with the toothed plate guide bracket; a gear at the output end of the gear driving motor is meshed with the toothed plate and used for driving the toothed plate to slide along the toothed plate guide support. The gear plate meshed with the output end of the gear driving motor is driven by the gear driving motor to slide in the height direction, the cushion is lifted up and down to achieve the zero-gravity function, and meanwhile the zero-gravity state of the cushion at different heights can be met.

    本发明提供了一种电动可调节长度的前连杆组件以及包含该前连杆组件的汽车座椅骨架,属于汽车座椅骨架技术领域。本发明的前连杆组件包括:滑轨前连接支架,其设置于汽车座椅骨架下方的滑轨上;齿板导向支架,其固定连接于滑轨前连接支架上,其远离滑轨前连接支架的一端与汽车座椅骨架的坐垫骨架框相连接;齿板,其与齿板导向支架滑动连接;齿轮驱动电机,其输出端的齿轮与齿板相啮合,用于驱动齿板沿齿板导向支架滑动。本发明通过齿轮驱动电机驱动与其输出端相啮合的齿轮板沿高度方向的滑动,实现坐垫上下抬升以达成零重力功能的实现,同时可满足不同高度时坐垫的零重力状态。
