A folding mechanism for a stroller including a cover, a front leg connector pivoted to the cover, a rear leg connector pivoted to the front leg connector, and a front guard member pivoted to the front leg connector is disclosed. A pair of connection arms extends from the front guard member. The folding mechanism includes a rotatable member pivoted to the cover and detachably connected to the connection arm. An abutting portion protrudes from the rotatable member. When the rear leg connector is unfolding, the rear leg connector abuts against the abutting portion and drives the front guard member rotating relative to the cover to an unfolded position. When the rear leg connector is folding, the rear leg connector is detached from the abutting portion to release the front guard member to a folded position.

A child stroller apparatus includes a first side segment connected fixedly with a first shell portion and a grip portion that are disposed adjacent to each other, a second side segment fixedly connected with a second shell portion that is pivotally connected with the first shell portion, a latch assembled in a cavity delimited at least partially by the first and second shell portions, the latch being movable between a locking position that prevents relative rotation between the first and second side segments and thereby locks the child stroller apparatus in an unfolded state for use, and an unlocking position for folding and unfolding of the child stroller apparatus, and a release actuator assembled adjacent to the grip portion and operatively coupled to the latch, the release actuator being operable to cause the latch to move from the locking position to the unlocking position.

A child stroller apparatus includes a stroller frame, and an adapter assembled with the stroller frame and having a first coupling portion and a second coupling portion, each of the first and second coupling portions being configurable as a mount for installation of a detachable part. The adapter is movable relative to the stroller frame to displace the first and second coupling portions, a first position of the adapter configuring the first coupling portion as the mount while maintaining an angle between the first coupling portion and the second coupling portion, and a second position of the adapter configuring the second coupling portion as the mount while maintaining the angle between the first coupling portion and the second coupling portion.

A collapsible stroller is disclosed, including a front axle frame member, a rear axle frame member, a handlebar frame member, a handlebar, and a hub. The hub includes a rotating attachment point for the front axle frame member, a rotating attachment point for the handlebar frame member, a fixed attachment point for the rear axle frame member. A cable connects the hub, and a rotatable handle on the handlebar frame member. When the rotatable handle is rotated, the cable causes the hub to collapse in two stages.

A carrier adjusting mechanism is applied to a stroller including a stroller frame and a carrier and includes a base, a locking structure, a locking device, and a release actuator. The base is connected to the stroller frame. The locking structure is connected to the carrier and pivoted to the base. The locking device is disposed between the base and the locking structure. The locking device includes a first engaging structure, a second engaging structure, and a locking member. The locking member is engaged with the first engaging structure at a first position or the second engaging structure at the second position. The release actuator is connected to the locking device via a link member for disengaging the locking member from the first engaging structure or the second engaging structure, to allow the locking structure to move between the first position and the second position together with the carrier.

A foldable car seat carriage includes a frame unit and an engagement unit. The frame unit includes two leg frames. Each of the leg frames includes two legs pivotable relative to each other, and a driving mechanism. The driving mechanism has opposite ends connected pivotally to the legs at first and second intersections. The engagement unit includes two bayonets. Each of the bayonets has a linking portion connected pivotally to the driving mechanism of a respective one of the leg frames. For each of the leg frames, change of a distance between the first and second intersections of the driving mechanism and the legs during pivot action of the legs converts a position of the engagement unit relative to the legs.

In some countries, it is a legal requirement for babies, infants and children under a certain age and/or height to be provided with a supplemental car seat when travelling in a vehicle. Furthermore, parents and guardians of children typically make use of a pram to transport a child. However, babies and infants grow quickly and may outgrow conventional car seats and prams within a year or two years. Therefore, a parent or guardian must typically provide several car seats and prams for their child. The present disclosure provides a child car seat system 100 including an infant carrier module 200 that may be releasably docked within a docking module 300 or a wheeled frame 400 to form a car seat and a pram respectively. The infant carrier module 200 may be arranged in an upright position or a lie flat position.

The disclosure provides a baby carriage brake mechanism and a baby carriage. The baby carriage brake mechanism includes a frame, a brake drive assembly, two linkage assemblies, and two brake locks. The brake drive assembly is disposed on the frame. The two linkage assemblies are respectively disposed on the frame on both of left and right sides. Both ends of the brake drive assembly are respectively in abutting connection with the two linkage assemblies. The two brake locks are fixedly connected to the two linkage assemblies, respectively. By driving the brake drive assembly to rotate, the brake drive assembly is configured to push the two linkage assemblies to slide up and down, so as to drive the two brake locks to move.

A rotating joint is provided, including a base, a first connecting base and a second connecting base. The first connecting base and the second connecting base are rotatably connected by a first rotating shaft. A second rotating shaft is further provided between the first connecting base, the second connecting base and the base. A first linkage unit is provided between the first connecting base and the base. A second linkage unit is provided between the second connecting base and the base. The first linkage unit coordinates with the first connecting base to rotate relative to the second connecting base when the base rotates relative to the second connecting base, and the second linkage unit coordinates with the second connecting base to rotate relative to the first connecting base when the base rotates relative to the first connecting base.

A frame folding and fixing device and a baby carrier are provided. The frame folding and fixing device includes a first locking device on a front leg of a frame and a second locking device on a handle of the frame. When the front leg of the frame is folded relative to the handle of the frame, the first locking device and the second locking device are rotated towards each other and locked; when the front leg of the frame is unfolded relative to the handle of the frame, the first locking device and the second locking device are rotated away from each other and unlocked. The frame folding and fixing device according to the disclosure may improve the overall aesthetics and use safety of the baby carrier, and may have a simple structure, low production cost and more convenient operation.
