  • Publication number: 20240017760
    Abstract: A baby stroller is provided and includes a stroller frame and a child carrier. The stroller frame includes two supports, a first fixing component, a second fixing component and a locking component. The first fixing component and the second fixing component are fixed on one and the other one of the two supports, respectively, and pivotally connected to each other. The locking component is movably disposed on the first fixing component and configured to engage with the second fixing component for restraining a folding action of the stroller frame. The child carrier is disposed on the stroller frame and pivotable relative to the stroller frame. The child carrier is for providing a releasing force to the locking component for disengaging the locking component from the second fixing component to allow the folding action of the stroller frame during a pivotal movement of the child carrier relative to the stroller frame.
