Seat frame front lifting mechanism for car seat

Abstract

The invention discloses a seat frame front lifting mechanism for a car seat. The seat frame front lifting mechanism comprises two groups of connecting rod assemblies which are arranged face-to-face, wherein a synchronous drive rod is connected between the two groups of connecting rod assemblies; the synchronous drive rod is provided with a drive handle; the drive handle is connected with a power device; the connecting rod assemblies comprise upper connecting rods and lower connecting rods; the lower ends of the upper connecting rods fixedly sleeve the synchronous drive rod; the upper ends of the lower connecting rods movably sleeve the synchronous drive rod; the power device comprises a screw rod motor; a housing of the screw rod motor is hinged to a supporting seat by a supporting lug; a screw rod of the screw rod motor is hinged to the drive handle; and the supporting seat is fixed onto the seat frame of the car seat. After the seat frame front lifting mechanism for the car seat is adopted, when the screw rod of the screw rod motor shrinks, the screw rod pushes and pulls the drive handle, so that the synchronous drive rod swings; the upper connecting rods fixedly connected to two ends of the synchronous drive rod rotate, the lower connecting rods hinged to the upper connecting rod rotate, the angles between the upper connecting rods and the lower connecting rods are changed, and the whole heights of the upper connecting rods and the lower connecting rods are changed, so that the aim of lifting is achieved.

Description
