Each of two ends of the connecting bracket assembly is connected to the first bracket assembly and the second bracket assembly respectively. A connecting end of the supporting assembly is rotatably connected to the connecting bracket assembly, a sliding end of the supporting assembly is slidably connected to either the first bracket assembly and the second bracket assembly or the connecting bracket assembly.

A collapsible stroller includes a stroller frame, at least one hinge mechanism, and a hinge lock mechanism. The stroller frame is movable between a deployed position and a collapsed position. The at least one hinge mechanism is on the stroller frame and allows for movement of the stroller frame between the collapsed position and the deployed position. The hinge lock mechanism is capable of a locked state and an unlocked state. In the locked state, the hinge lock mechanism locks the at least one hinge mechanism to maintain the stroller frame in the deployed position. In the unlocked state, the hinge lock mechanism allows the stroller frame to move from the deployed position toward the collapsed position. The hinge lock mechanism includes a manually actuated first linkage and a manually actuated second linkage.

A braking mechanism and a child stroller, where the braking mechanism includes a pedal part and a housing part connected to the pedal part. A sliding groove is arranged on an inner surface of the housing part. The braking mechanism is further provided with an elastic piece part, the elastic piece part is provided with a highest point, and the braking mechanism is prevented from a false locking through a cooperation of the sliding groove and the highest point. The braking mechanism has a function of preventing false locking, which can avoid a false locking phenomenon of the child stroller and improve the safety of the child stroller in use.

A foldable stroller includes a frame and wheels installed at a bottom of the frame. The frame has a folded state and an unfolded state. The frame includes a first bracket assembly, a second bracket assembly, a connecting bracket assembly and a supporting assembly. The second bracket assembly is arranged opposite to the first bracket assembly in a front-back direction. Each of two ends of the connecting bracket assembly is connected to the first bracket assembly and the second bracket assembly respectively. A connecting end of the supporting assembly is rotatably connected to the connecting bracket assembly, a sliding end of the supporting assembly is slidably connected to either the first bracket assembly and the second bracket assembly or the connecting bracket assembly.

A brake mechanism is disclosed. The brake mechanism includes a hub, a fixed base, a retainer, and a pedal assembly. The hub is provided with a first engagement portion. The fixed base is fastened to the hub, and provided with a second engagement portion capable of being engaged with and locked with the first engagement portion. The second engagement portion is kept disengaged from the first engagement portion when the retainer is at the first position, and the second engagement portion is kept engaged with and locked with the first engagement portion when the retainer is at the second position. When force along a first direction is applied to the pedal assembly, the retainer moves from the first position to the second position or from the second position to the first position.

An intermittent movement device according to the application includes: a housing; a driving member, disposed in the housing, and capable of rotating around a first axis; a plurality of engagement teeth, circumferentially distributed on the driving member based on the first axis; an operating member, capable of performing reciprocating movement between an initial position and an acting position with respect to the driving member around the first axis; wherein when the operating member moves from the acting position to the initial position, the operating member passes over one of the engagement teeth to return from the acting position to the initial position, and the driving member does not rotate with the operating member. The application further discloses a wheel locking structure and a stroller.

Provided is a smart stroller including a stroller, master control module and power control module. The stroller includes a chassis support, a front wheel support which two front wheels are disposed at, a rear wheel support which two rear wheels are disposed at, a seat, handle, guardrail and canopy. The master control module is disposed on a base of the handle of the stroller. The master control module includes a controller, brake controller, first wireless communication device, and global positioning system. The power control module is disposed at the bottom of the rear wheel support and includes a second wireless communication module, power source module, foot brake component, drive motor, deceleration mechanism, and drive controller. The smart stroller is applicable to a global positioning system and an anti-theft system and capable of performing video surveillance, automatic braking, music playing and storytelling to ensure user safety and captivating user experience.

The application discloses a parking structure including: a locking structure, capable of switching between a locked position that prevents a wheel from rotating and a released position that allows the wheel to rotate; and a drive structure, connected to the locking structure; wherein the drive structure is capable of being driven from an initial position to an active position, and automatically returning from the active position to the initial position, so as to perform a reciprocating motion, and one reciprocating motion of the drive structure causes the locking structure to switch from the released position to the locked position or from the locked position to the released position. A child stroller is also disclosed.

A foldable baby stroller includes a baby stroller main body, and the baby stroller main body includes a folding bottom plate; the baby stroller features convenient and efficient folding operation. By pressing the unlocking part of the latch, the locking of the telescopic rods can be quickly released by using the lever principle. When locking, it only needs to press the locking part to complete. During the folding process, the movement paths of the folding bottom plate and the folding side frame do not interfere with each other. The folding bottom plate realizes flipping and closing through the hinge connection piece, and the folding side frame adapts to the elevation of the middle connection piece by extracting the sleeve rod from the sleeve. The two work together smoothly. The supporting vertical frame remains fixed and moves closer with the stroller.
