A quick release structure for front wheels of baby strollers includes an upper mount disposed on one leg support thereof. A fixing pin is arranged on the upper mount for inserting into a locking hole on the leg support. Moreover, a lower mount assembled with a wheel is set on the bottom of the upper mount. A connection rod at the top of the lower mount is inserted into the upper mount. A fixing groove for locking with the fixing pin is formed around the side wall close to the top of the connection rod. A positioning slot is provided on the bottom of the upper mount for mounting a L-shaped positioning rod pivoted on the lower mount. Thus the stroller can keep moving forward without changes in directions by pressing the positioning rod to be locked into the positioning slot for the purposes of easy assembling, storage and transportation.

A stroller has a frame reconfigurable between an in-use configuration and a folded configuration. A fold joint on the frame, when in a latched orientation, retains the frame in the in-use configuration. A seat is supported by the frame and a tray extends across and is spaced forward from the seat assembly. The fold joint is coupled to a portion of the tray and is configured to: a) move the tray to a deployed position relative to the seat when the frame is moved to the in-use configuration; b) retain the tray in the deployed position when in the in-use orientation; and c) release and allow the tray to move to a folded position when the frame is moved to the folded configuration. The fold joint is configured to hide and covers the various fold latch and tray fold components.

A folding device for a baby carriage has an operating arm, a first cover, an engaging unit, an elastic unit, a first abutting unit, a second abutting unit, and a second cover. The operating arm has two opposite ends. The first cover is connected to one of the two opposite ends of the operating arm. The first cover and the second cover are pivotally mounted with each other. The engaging unit, the elastic unit, the first abutting unit, and the second abutting unit are received in the first cover and the second cover. The folding device for a baby carriage not only avoids dust or foreign objects accumulating on the inner structures received inside the first cover and the second cover, but also prevents fingers from accidentally pinching.

The invention relates to a baby stroller which comprises a stroller frame used for forming a connecting rod mechanism and provided with an unfolding part and a folding part, a front wheel assembly arranged on the front part of the bottom of the stroller frame, a back wheel assembly arranged on the back part of the bottom of the stroller frame, a seat mechanism and a locking mechanism for locking the stroller frame under an unfolding part. The stroller frame further comprises an electric drive mechanism capable of electrically unfolding or folding the stroller frame. The electric drive mechanism comprises a transmission mechanism arranged between two members of the stroller frame and a motor for controlling the operation of the transmission mechanism, wherein the two members of the stroller frame are rotatably or slidably connected. The stroller frame further comprises the electric drive mechanism capable of electrically unfolding or folding the stroller frame so that the operation is more convenient.

A removable wheel device includes a wheel unit, a housing, and a locking unit. The wheel unit includes a wheel body and a wheel axle formed with an annular groove. The wheel axle is extendible removably into the housing. The locking unit includes an actuator connected pivotally to the housing, an elastic member mounted between an operating end portion of the actuator and the housing, and a locking pin connected to a force transmitting end portion of the actuator. The operating end portion is depressible to move the force transmitting end portion from a locking position, where the locking pin extends into the annular groove to prevent removal of the wheel axle from the housing, to an unlocking position, where the locking pin is disengaged from the annular groove to permit removal of the wheel axle from the housing.

The invention relates to a withdrawable infant carrying device at least comprising a supporting frame, a connecting frame, a first locking mechanism and a second locking mechanism. The supporting frame comprises a front tripod, a rear tripod and a handspike. The connecting frame is respectively pivoted on the front tripod and the handspike; the first locking mechanism is arranged between the handspike and the connecting frame and used for locking the position of the handspike relative to the connecting frame; the second locking mechanism is arranged between the connecting frame and the front tripod and has a locking state and an unlocking state, wherein the second locking mechanism in the locking state is used for locking the connecting frame and the front tripod, and the second locking mechanism in the unlocking state permits the connecting frame to rotate relative to the front tripod.

A stroller having a central hub system that is reversible and foldable is provided. In one example, support members of the stroller chassis (e.g., members supporting the front wheels, back wheels, handle bar(s), and child seating surface) extend from the central hub system and are selectively rotatable there around. In some examples, the central hub system allows a user to collapse or fold the stroller from a first operational position (e.g., suitable for supporting a child) to a second collapsed position (e.g., where the support members rotate around the central hub system together to a more compact position relative to the operational position). In some examples, the collapsed position may be achieved in a single step (e.g., motion), and by one hand, of the user. The central hub system may also allow for reversing the handlebar to support the child in either a forward or rear facing configuration.
