A stroller frame includes a handle assembly, a front leg assembly and a rear leg assembly having rotating end hubs which are pivotably connected to each other about a hub axis to be rotated so as to allow the stroller frame to transform between folded and unfolded states. A tray mounting assembly is coupled with a tray, is rotatably mounted on one of two rotating end hubs, and is rotated along with the relative rotation of the end hubs to convert the tray to folded and unfolded positions. A tray latching assembly is disposed to retain and support the traymounting assembly to keep the tray stable in the unfolded position when the stroller frame is in the unfolded state.

A child stroller apparatus includes a standing frame having a first and a second leg frame, a handle frame pivotally connected with the first leg frame via a joint structure that defines a pivot axis about which the handle frame is rotatable relative to the first leg frame, the handle frame further being pivotally connected with the second leg frame via a pivot connection away from the pivot axis, a first coupling part pivotally connected with the joint structure in a coaxial manner, and a locking mechanism including a front guard latch disposed adjacent to the joint structure. The front guard latch is movable between a locking position where the front guard latch locks the first coupling part to the joint structure, and an unlocking position for rotation of the first coupling part relative to the joint structure.

A child seat includes a seat frame, a tray, a tray latch and a linking member. The seat frame includes a first frame portion having a side coupling part, and a second frame portion pivotally connected with the side coupling part. The tray is pivotally connected with the side coupling part for rotation. The tray latch is pivotally connected with the side coupling part, and can engage with the tray for locking the tray to the side coupling part and disengage from the tray for rotation of the tray. The linking member is operatively connected with the tray latch and the second frame portion, wherein a rotation of the second frame portion for collapsing the child seat causes a movement of the linking member that urges the tray latch to rotate relative to the side coupling part and disengage from the tray.

A seat baffle and a baby stroller are introduced. The baby baffle is disposed in a baby carrier. The baby carrier includes a seat and a support rod erected relatively to the seat and straddling a front end of the seat, the seat baffle includes a baffle cloth, one end of the baffle cloth is fixed to the front end of the seat, the other end of the baffle cloth is detachably fixed to the support rod for shielding the front end of the main body. When the baffle cloth is fixed on the support rod, the front end of the main body is shielded, which is suitable for small babies; after the baffle cloth is detached from the support rod, the front end of the main body becomes open, which is suitable for large babies. The seat baffle can switch between two usage statuses in the baby carrier.

A bumper bar assembly for a stroller includes a first end bar member, a second end bar member, and an intermediate member connected with and disposed between the first end bar member and the second end bar member. The first end bar member is configured to connect with a stroller frame at or adjacent to a first side of the stroller frame. The second end bar member is configured to connect with the stroller frame at or adjacent to a second side, which is opposite to the first side, of the stroller frame. The intermediate member is pivotable with respect to at least of the first bar member and the second bar member about at least two axes.

An infant stroller apparatus includes a front and a rear leg frame respectively having a first and a second side portion, a handle frame having a side segment, a seat frame and a bar linkage. The first and second side portions and the side segment are pivotally connected with one another about a first pivot axis. The seat frame is pivotally connected with the side segment about a second pivot axis. The bar linkage has a first and a second end respectively connected pivotally with the second side portion and the seat frame about a third and a fourth pivot axis. When the infant stroller apparatus is deployed, the second pivot axis is above the first pivot axis, the third pivot axis is above the first pivot axis, and the fourth pivot axis is above and behind the first pivot axis.
