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.

Stroller frame comprising at least one electric motor, for assistively driving the stroller frame, at least one wheel connecting device, in particular wheel axle, and at least one battery module connected or connectable to the wheel connecting device, which in the assembled state is arranged at least partly outside the wheel connecting device and is arranged at least predominantly below a level of an upper end of the wheel connecting device or is arranged at least partly below the wheel connecting device.

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 stroller frame (100) includes a front leg (10), a bottom tube (30), a rear leg (20), an upper support member (40) and a lower support member (50). The front leg (10), the bottom tube (30), the lower support member (50) and the upper support member (40) are pivotally connected to each other to form a four-bar linkage structure. The rear leg (20) is connected to an end of the bottom tube (30). A lock mechanism (60) is disposed at a pivot joint between the upper support member (40) and the lower support member (50). The lock mechanism (60) is able to lock the upper support member (40) and the lower support member (50) at an expanded angle, such that the front leg (10) is able to be expanded with respect to the bottom tube (30). The lock mechanism (60) is unlocked to release the upper support member (40) and the lower support member (50), such that the front leg (10) is able to be folded with respect to the bottom tube (30).

The delayed-action collapsible stroller device may be simple to operate, compact when folded, and robust and reliable during both use and storage. Such a device may further comprise a delayed-action folding mechanism to maximize its compactness when folded, and may further comprise advanced locking mechanisms to enhance its structural rigidity and ability to carry heavier users. The delayed-action collapsible stroller device may further comprise standardized mounting points and a plurality of accessories to enhance its functionality.

A parking brake assembly includes a disc defining an aperture and a ramp located adjacent to the aperture; a pedal configured to rotate the disc in a locking direction or an unlocking direction; and an actuator including a body and a spring biased to push the body towards the aperture, the actuator further including a pin positioned and arranged to ride along the ramp when the disc is rotated relative to the actuator, wherein spring is allowed to push the body through the aperture and into a mating hole, of or associated with a wheel, when the disc is rotated in the locking direction such that the pin rides down the ramp, and wherein the spring is prevented from pushing the body through the aperture and into the mating hole when the disc is rotated in the unlocking direction such that the pin rides up the ramp.

A wheeled childcare device is provided that can reliably maintain a braking state. The wheeled childcare device includes: a body frame; a pair of arm members each having an upper end pivotally held at a lower end of a corresponding one of a pair of legs via a corresponding one of a pair of pivot shafts; a pair of wheels each rotatably supported at a lower end of a corresponding one of the arm members via a corresponding one of a pair of axles; and a brake mechanism configured to stop rotation of the wheels and including a pair of lock members, an operating member, and a connecting member connecting the operating member with the lock members. The brake mechanism is configured to perform a braking operation and maintain a braking state without being interfered with by a pivoting motion of the arm members.

A wheeled childcare device is provided that can reliably reduce or eliminate the possibility of twisting of a wire. The wheeled childcare device includes legs, a caster mechanism, and a brake mechanism. The brake mechanism includes a pair of lock members, an operating member, and a connecting member connecting the operating member with the lock members. The connecting member includes a pair of moving members configured to move in response to an operation of the operating member, an elongated member connecting the operating member with the moving members, and a pair of driven members each configured to be rotatable relative to a corresponding one of the moving members, and each configured to follow movement of the corresponding moving member. Each of the lock members is configured to be displaceable between engaged and disengaged positions in conjunction with movement of the corresponding driven member.
