The turning plate 21 is connected to the cushion frame 11 in a shaft manner through the connecting shaft 212, so that the front end of the turning plate 21 can turn downwards around the connecting shaft 212, and the front end of the turning plate 21 can be supported on the automobile seat, so that the front end of the child seat is supported to a certain height, and the forward turning of the child seat is well resisted.
Preferably, limit posts 211 are disposed on both sides of the turning plate 21, and driving members 221, connecting rods 222, connecting sleeves 223 and rotating pins 224 are correspondingly disposed on both sides of the cushion frame 11, so as to improve stability of the turning plate 21.
The present invention has been described in detail with reference to the embodiments of the drawings, and those skilled in the art can make various modifications to the invention based on the above description. Accordingly, certain details of the illustrated embodiments are not to be taken as limiting the invention, which is defined by the appended claims.
