Abstract

The present invention provides a child safety seat. The pitching angle adjustment of the child safety seat is achieved through the angle adjustment mechanism. The connecting rod is connected to the driving mechanism, and the shaft sleeve sleeving the connecting rod is driven by the motor. The gears are mounted at the two ends of the shaft sleeve, and the gears are driven by the shaft sleeve to move on the rack. The rack is mounted on the base plate, so that the seat body can adjust the angle on the base plate. The connecting rod and the seat frame form the fixed supporting structure, so that the stability of angle adjustment is better. By the arrangement of the protective device on the seat portion, the probability of accidentally injuring a child during the turning of the seat body is reduced, and the safety of use is improved.
