The invention provides a frame folding mechanism, a frame locking mechanism, a backrest unlocking mechanism and a stroller. A handle, a front foot, a seat portion and a linking member of the frame folding mechanism form a planar linkage mechanism. The handle and the front foot can be driven to rotate and fold toward a rear foot, so as to drive the seat portion to rotate and fold. The frame locking mechanism can drive a sliding member and a frame expansion locking member to slide by an unlock driving mechanism, such that the frame expansion locking member disengages from a handle locking hole and a front foot locking hole to unlock a frame. The backrest unlocking mechanism has a backrest locking member. The unlock driving mechanism can drive the backrest locking member to slide, such that the backrest locking member disengages from a backrest portion to unlock the backrest portion.

A mobility assistance apparatus includes first and second frames positioned on left and right sides of a user; a hinge arm mechanism coupled to the first and second frames; and a pivotable securing unit or a walking seat coupled to the frames to transfer at least a portion of the user's body weight from the legs and to transfer weight through the user's hip or pelvis to the first and second frame enabling the user to stand or work for an extended period without requiring the user's arms to hold the frame; a wheel coupled to the first and second frames; a brake coupled to the wheel to provide friction to the wheel when actuated; and a tensioner coupled to the brake to adjust cable tension during wheel braking.

A folding device of a stroller includes a folding assembly which is configured to fold the stroller and a safety assembly. The folding assembly includes an operable pull handle. The pull handle is slidably sleeved over a handle frame of the stroller and is movable between a holding position and a release position. The safety assembly is configured to cooperate with the folding assembly, in which the safety assembly includes a locking member for preventing misoperation of the pull handle, and the locking member is switchable between a locked position and an unlocked position. The locking member is configured to prevent the pull handle from moving to the release position responsive to the locking member being in the locked position; and the locking member is entirely located inside the handle frame responsive to the locking member being in the unlocked position.

A motor brake device, comprising a supporting assembly (1), a movable rotating disc (2), a pressing assembly (4), a lower cover (5), a sliding block (6), an elastic member, a brake assembly (7), and an upper cover (8). The supporting assembly (1) is fixed to a bottom housing (103) of a motor (10); a motor shaft head portion (102) extends out of a housing (104) of the motor (10), and a motor shaft tail portion (101) extends out of the bottom housing (103) of the motor (10) and penetrates through the supporting assembly (1); the movable rotating disc (2) is mounted on the motor shaft tail portion (101); the motor shaft tail portion (101) drives the movable rotating disc (2) to rotate synchronously; the pressing assembly (4) is movably connected to the lower cover (5); the lower cover (5) and the supporting assembly (1) are connected and fixed by means of a first connecting member; the sliding block (6) is connected to the elastic member, the sliding block (6) is connected to the brake assembly (7), and the sliding block (6) and the elastic member are mounted in the upper cover (8); the upper cover (8) and the lower cover (5) are connected and fixed by means of a second connecting member. During braking, the brake assembly (7) can enable the sliding block (6) to move synchronously, the sliding block (6) drives the pressing assembly (4) to move towards the movable rotating disc (2), and the pressing assembly (4) can be in contact with and press the movable rotating disc (2), so that the movable rotating disc (2) stops rotating, the elastic member enables the sliding block (6) to reset after the brake is released, and the pressing assembly (4) does not press the movable rotating disc (2) any more.

A handbrake structure includes a fixing base, a linking member and a brake handle. The fixing base is located on a handle of a moving apparatus. The linking member is located on the fixing base, wherein a first portion of the linking member is connected to a first brake wire, and a second portion of the linking member has a first limit part. The brake handle is located on the linking member, wherein a first portion of the brake handle is connected to a second brake wire. When the brake handle is rotated in a first direction, the brake handle pushes the first limit part to rotate the linking member, and the linking member pulls the first brake wire. When the brake handle is rotated in a second direction different from the first direction, the brake handle pulls the second brake wire.

An unlock device includes at least one operating member, a first unlock module and a second unlock module. The at least one operating member is movably disposed on a frame, wherein the frame is equipped with a first lock mechanism and a second lock mechanism. The first unlock module is movably disposed on the frame and connected to the first lock mechanism. The second unlock module is movably disposed on the frame and connected to the second lock mechanism. The at least one operating member moves to drive the first unlock module to move to unlock the first lock mechanism or drive the second unlock module to move to unlock the second lock mechanism.

A child transport carrier includes a handle bar and a rotatable brake actuator disposed along a lengthwise axis of the handle bar. A first cable having a first end and a second end is coupled to the rotatable brake actuator. A first wheel brake of a first wheel is coupled to the first end of the first cable. Rotating the rotatable brake actuator around the lengthwise axis of the handle bar activates the first wheel brake.

A carrying apparatus provides a self-powered, rechargeable, technologically adaptable transport vehicle, such as a stroller. The apparatus includes efficient seating and storage capacities for efficiency items, such as pertinent baby supplies. Because the apparatus is self-powered, the physical stress of carrying at least one item is reduced. Furthermore, the apparatus uses technology to maintain perpetual power for operation, and to regulate and monitor the propulsion of the apparatus during transport. The apparatus may be pushed or pulled in multiple directions at varying velocities. The apparatus includes braking and accelerating capacities. A frame portion supports a seat portion, such as a buckled baby seat; a storage portion, such as a cargo mesh. A rechargeable power source powers a motor that turns a drive shaft for propulsion. Brakes position at the wheels. A control portion provides a display and levers for accelerating and decelerating.

A convertible car seat, carrier and stroller device includes a car seat that has a frame, which is rigid. The car seat is shaped and sized to a child. A handle, which is extendable, is coupled to a back of the frame. A wheel assembly is coupled to and positioned in a housing that is coupled to a bottom of the frame. The wheel assembly is extensible from the housing and operationally coupled to the handle. Extending the handle lowers the wheel assembly and retracting the handle raises the wheel assembly. The car seat is couplable to a base that is configured to couple to an interior of a vehicle. The base is couplable to the interior of a vehicle and positioned to secure the car seat in the vehicle.

A child push chair frame, such as a child push chair sports frame, buggy frame or similar vehicle frame for children, includes two rear wheels, at least one front wheel, and a pusher for pushing the child push chair frame. The child push chair frame may also include stabilizing struts that are foldable from a spread-apart travelling position into a fully folded-together transportation position and vice versa, and are latchable between these two positions and at least one further position, such as a parking position.
