Abstract: The present disclosure discloses a child seat and stroller three-in-one apparatus, and relates to the field of child seats. The apparatus includes a frame set and a basket set. The frame set is inserted and matched with the basket set; the frame set includes a base, front feet, rear feet, and lock pins; and rotating shafts are arranged on two sides of the base respectively, shaft holes in running fit with the rotating shafts are provided in upper ends of the front feet and the rear feet respectively, and the upper ends of the front feet and the rear feet are connected in series to and matched with the rotating shafts. The apparatus can achieve a three-in-one function of a child seat, a stroller, and a basket, may arbitrarily switch from the baby stroller to the child safety seat, and is stable in overall structure and very convenient to use.

Abstract: The present invention discloses a retractable side protecting airbag for a child safety seat which includes a side protecting base provided on an outer side surface of the seat body. Specifically, the side protecting base is provided with the retractable side protecting airbag. The retractable side protecting airbag is correspondingly provided with an air deflating hole. The side protecting airbag is internally provided with a resetting structure. An outer end of the retractable side protecting airbag is provided with a side protecting cover. The protecting cover and the side protecting base are locked to each other and work collaboratively for folding the retractable side protecting airbag. The present invention has a reasonable structure and a long distance for crumpling, and is capable of providing buffering and effective energy absorption, thereby greatly reducing the damage to children from side crashes.

Abstract: A pump-valve integrated mechanism includes an air pump driven by a power source. A main air channel provided inside the valve base is connected to the air pump and has a decompression structure. The main air channel is connected to an air inflation structure which includes a branch air channel and an air nozzle. A check valve is provided inside the branch air channel. The branch air channel between the check valve and the air nozzle is provided with an air deflation hole. An electromagnetic valve is provided between the air nozzle, the air deflation hole, and the check valve. During air inflation, the electromagnetic valve controls the check valve to become connected to the air nozzle, and the air deflation hole is closed. During air deflation, the electromagnetic valve controls the air nozzle to become connected to the air deflation hole and the check valve is closed.
