摘要： The present invention discloses a folding device and a child carrier therewith. The folding device is installed between a frame and a seat of the child carrier and includes a sliding structure, a mounting base and a linking component. The sliding structure is fixedly disposed on or inside a handle of the frame. The mounting base is slidably disposed on the sliding structure for detachably engaging with the seat. A first end of the linking component is pivotally connected to the mounting base. A second end of the linking component is pivotally connected to a rear leg of the frame. The linking component is driven to drive the mounting base to slide relative to the sliding structure when the handle pivots relative to the rear leg. The folding device and the child carrier have advantages of easy operation, simple structure and compact folding of the frame.

摘要： A stroller includes a frame, a first locking mechanism, a folding mechanism and a second locking mechanism. The frame is configured to be folded and unfolded between a folded state and an unfolded state. The first locking mechanism is disposed on the frame and for locking the unfolded frame and restraining the frame from being folded when the frame is in the unfolded state. The folding mechanism is movably disposed on the frame and connected to the first locking mechanism for driving the first locking mechanism to allow the frame to be folded. The second locking mechanism is disposed on the folding mechanism and separably abuts against the frame for restraining the folding mechanism from driving the first locking mechanism so as to lock the unfolded frame.
