A stroller includes a frame, a sliding member and a seat fixing base. The sliding member is rotatably connected to the frame. The seat fixing base is rotatably connected to the frame and slidably connected to the sliding member. When the frame is folded, the frame drives the seat fixing base to slide with respect to the sliding member.

A folding joint and a child carrier are provided. The folding joint includes a first holder body having a first accommodating cavity and a first engaging portion; a second holder body pivotally connected to the first holder body, and having a second accommodating cavity and a second engaging portion; a locking member having an unlocking position, and first and second locking positions; and an elastic member for applying a force to the locking member. When the locking member is in the first locking position or the second locking position, it is simultaneously engaged with the first engaging portion and the second engaging portion. An axial engaging depth of the locking member engaging with the second engaging portion is a first depth (L1) in the first locking position, which is greater than that in the second locking position.

A foldable stroller, movable between an unfolded state and a folded state, comprising: a central frame element (101) extending in a lateral direction of said stroller; a front wheel frame element (102) which is at one outer end pivotably connected to said central frame element (101) around a first axis, which first axis extends in said lateral direction, and comprising at least one front wheel (121) at its other outer end; a push bar connector frame element (103) which at one outer end is pivotably connected to said central frame element (101) around a second axis, which second axis extends in said lateral direction, and which at its other outer end comprises a push bar frame element (105) with a push bar (151); a first and second rear wheel frame element (104) each connected to said central frame element (101) at one outer end, and each comprising a rear wheel (141) at their other outer end; wherein said first and second rear wheel frame element (104) is each pivotably connected to respective opposite outer lateral ends of said central frame element (101) around respective third and fourth axes, which third and fourth axes extend mutually substantially parallel and substantially perpendicular to said first and second axes; such that a pivoting movement of said front wheel frame (102) element and said push bar connector frame element (103) from the unfolded state towards each other in the folded state results in said first and second rear wheel frame elements (104) being pivoted from the unfolded state towards each other in the folded state, and vice versa.

The disclosure provides an auxiliary mechanism for assisting folding or unfolding a frame of a pushcart as well as a pushcart. The frame includes a first rod and a second rod being pivotable relative to each other. When the first rod and the second rod are relatively pivoted to a first position, the frame is in an unfolded state; and when the first rod and the second rod are relatively pivoted to a second position, the frame is in a folded state, wherein the auxiliary mechanism includes an elastic member, the elastic member drives the first rod and the second rod to be relatively pivoted towards the first position or towards the second position. The auxiliary mechanism according to the disclosure facilitates the user to unfold or fold the frame more easily, and enables the frame to be unfolded or folded in place, thus avoiding potential safety hazards.

A lightweight collapsible stroller is provided. The stroller includes: a frame including a first portion movable relative to a second portion; a drive mechanism coupled to the frame, which moves the first portion relative to the second portion, thereby transitioning the frame between an open position and a closed position; and a latch mounted to the frame. The latch is positioned to engage at least a portion of the first portion or the second portion when the frame is in its open position to restrict the first portion from moving relative to the second portion. Upon actuation, the drive mechanism causes the latch to release, such that the first portion of the frame moves relative to the second portion of the frame, thereby allowing the frame to transition to the closed position.

A stroller includes a frame, a sliding member and a seat fixing base. The sliding member is rotatably connected to the frame. The seat fixing base is rotatably connected to the frame and slidably connected to the sliding member. When the frame is folded, the frame drives the seat fixing base to slide with respect to the sliding member.

A collapsible stroller includes a stroller frame moveable between a deployed position and a collapsed position and a latch mechanism. The stroller frame includes a first leg, a second leg and a handle support member. The handle support member is pivotable with respect to the first leg or the second leg. The latch mechanism includes a latch body and a catch. The latch body is positioned internally of the second leg. When the stroller is in the deployed position, the latch body is blocked from view by the second leg when the stroller frame is viewed in a side elevation view. The catch is provided on or connected with the first leg or the handle support member. The latch body cooperates with the catch to selectively connect the latch body with the catch when the stroller is in the collapsed position.

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.

Provided is a foldable stroller, having a foldable chassis movable between an unfolded condition and a folded condition, a foldable bassinet or seat supported by the foldable chassis and movable between an unfolded condition and a folded condition, and which has a support surface on which a passenger may recline or sit when the foldable bassinet or seat is in its unfolded condition, a first locking mechanism which when engaged prevents the foldable bassinet or seat from moving from its unfolded condition to its folded condition and which when released permits the foldable bassinet or seat to move from its unfolded condition to its folded condition, wherein movement of the foldable chassis from its unfolded condition towards its folded condition releases the first locking mechanism, and a second locking mechanism which when engaged prevents the foldable chassis from moving from its unfolded condition to its folded condition and which when released permits the foldable chassis to move from its unfolded condition to its folded condition.

A folding hook structure comprising: a shell, fixed to the first object, and at least partially accommodates other parts of the folding hook structure; a rotating disk, fixed to the second object, and disposed in the shell to be rotatable around a rotation center in respect to the shell, with a folding hook groove disposed on a disk surface of the rotating disk, the folding hook groove including a circumferential section extending in a circumferential direction of the rotating disk with the rotation center as a center, and a radial section extending from the circumferential section along a radial direction of the rotating disk; a folding hook, disposed in the shell, and arranged movable between a locked position and a released position along the radial direction of the rotating disk, the folding hook being inserted in the folding hook groove.
