SUPPORTING LEG POSITIONING STRUCTURE AND CHILD SAFETY SEAT

The present disclosure provides a support leg positioning structure and a child safety seat including the same. The support leg positioning structure includes a folding/unfolding positioning assembly (1), a connecting assembly (2), and a support leg (3) hingedly connected to the connecting assembly. The folding/unfolding positioning assembly (1) includes a first positioning member (11) and a second positioning member (12) configured to engage with each other. The first positioning member (11) is movably connected to the connecting assembly (2). A first end of the second positioning member (12) is connected to the support leg (3). A second end of the second positioning member (12) is hingedly connected to the connecting assembly (2). When the support leg (3) is in an unfolded position, the first positioning member (11) and the second positioning member (12) are locked to each other. In the support leg positioning structure of the present disclosure, with the arrangement of the folding/unfolding positioning assembly (1) between the connecting assembly (2) and the support leg (3), the support leg (3) can be locked with the connecting assembly (2) when the support leg (3) is in the unfolded position, thereby effectively supporting the child safety seat to ensure the safety of a child in the child safety seat on a vehicle. The folding/unfolding positioning assembly (1) features a simple structure and convenient and reliable operation.
