Description
Technical Field
The invention relates to the technical field of child safety seats, in particular to a supporting foot set with a buffering structure and a child safety seat with the same.
Background
The child safety seat is a device which is arranged on a car seat and binds an infant on the child safety seat through a binding device, under the condition that the car is braked emergently or collided accidentally, the child safety seat firmly binds the infant through a shell and the binding device, and the injury to the infant is reduced by limiting the body movement of the infant, so that the injury probability of the infant can be reduced.
The child safety seat generally comprises a base and a seat body arranged on the base, wherein the rear end of the base is provided with a connecting mechanism to be connected with a fastener on a car seat, so that the seat body is temporarily fixed on the car seat, if the base is not fixed well, the base can slide towards the advancing direction of the car or roll over due to the inertia effect when the car is braked emergently, and in view of the above, the front end of the base is provided with a supporting leg, the lower end of the supporting leg can be supported on the floor in the car when the child safety seat is used, so that the base can be prevented from sliding towards the front, rolling or falling off when the car is braked emergently. However, when the impact force is relatively large, if the leg is not buffered at all, the impact force is still transmitted to the infant through the base and the seat body, thereby causing injury to the infant.
Therefore, there is a need to provide a supporting leg assembly and a child safety seat with simple structure and buffering function to solve the above-mentioned problems in the prior art.
