The invention discloses an automobile chair framework lifting mechanism. The automobile chair framework lifting mechanism comprises a chair framework body arranged on a base, wherein the front part of the chair framework body is connected with the base through a front lifting device, and the rear part of the chair framework body is connected with the base through a rear connecting rod; the front lifting device comprises two groups of connecting rod assemblies, a synchronous driving rod is connected between the two groups of connecting rod assemblies, the connecting rod assemblies comprise upper connecting rods and lower connecting rods, the upper ends of the upper connecting rods are hinged to the chair framework body, the lower ends of the upper connecting rods are fixed on the synchronous driving rod in a sleeving manner, the upper ends of the lower connecting rods are movably arranged on the synchronous driving rod in a sleeving manner, and the lower ends of the lower connecting rods are hinged to the base. According to the technical scheme, a screw of a screw motor stretches out and draws back, the synchronous driving rod is driven to swing, the upper connecting rods fixedly connected at the two ends of the synchronous driving rod rotate, the lower connecting rods hinged to the upper connecting rods rotate, angles between the upper connecting rods and the lower connecting rods vary, the variation of the whole height of the upper and lower connecting rods is caused, and the purpose of regulating the angle of the chair framework is achieved. Meanwhile, the front lifting device is matched with the rear connecting rod, and the chair framework height is regulated.
