The present disclosure provides an easy assembling and disassembling wheel component, including a wheel, a rotation shaft and an engaging member, wherein a mounting hole is disposed on a center of the wheel, an accommodating groove is disposed at one end of the rotation shaft, the engaging member is movably engaged in the accommodating groove and is swingable between a first position and a second position. When the engaging member is in the first position, the engaging member and the rotation shaft can pass through the mounting hole of the wheel; when the engaging member is in the second position, the rotation shaft is connected with and locked to the wheel. The easy assembling and disassembling wheel component according to the present disclosure has advantages of simple structure, quick and convenient assembling and disassembling. And, the present disclosure also provides five kinds of easy assembling and disassembling wheel components.

A seat height adjustment mechanism includes a locking bar and a locking element. The locking bar is disposed in a stroller frame and has locking holes spaced apart. Each of the locking holes has a stop portion protruding therein. The locking element is mounted on a seat and has an engaging end. The engaging end is separably engaged in any one of the locking holes and has an engaging hook protruding in a direction, and the direction is crossed with another direction in which the engaging end moves when the engaging end is separating from the locking hole. The engaging hook separably presses against the stop portion. Therefore, the engaging end cannot separate from the locking hole. Even when wrongly operated, the locking element cannot be rotated and unlocked and thereby prevents the seat from unnecessarily sliding downward, so as to ensure safety of a baby at the seat.

A transportation apparatus (1) comprises a frame (12) having an engagement portion or receiving portion (14) adapted to receive one or more occupant support devices (16); and drive means (20) configured to enable an occupant of the transportation apparatus (1) to power, drive and/or steer the transportation apparatus (1). The drive means (20) has a first configuration or position and a second configuration or position, wherein the drive means (20) is closer to the engagement portion or receiving portion (14) of the frame (12) in the second configuration or position than in the first configuration or position.

A baby stroller for transporting an infant at speeds faster than normal walking is disclosed. This baby stroller can be folded to make it easier to stow and transport. The folding mechanism, a unique feature of the design is directed toward compactness, ease of use, reliability, and reduction in manufacturing costs.

A child stroller frame includes a first and a second frame portion, a pivoting part and a linkage. The second frame portion has a front end and a rear end, the front end of the second frame portion being pivotally connected with the first frame portion. The pivoting part has one end fixedly connected with a rear wheel support member and another end pivotally connected with the rear end of the second frame portion. The linkage movably couples the first frame portion to the pivoting part, and has an intermediate portion pivotally connected with the second frame portion, whereby the first frame portion and the rear wheel support member are movably linked for folding in a concurrent manner toward the second frame portion.

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.

Various embodiments of a collapsible stroller configured to form at least a compact collapsed configuration are described. In some embodiments, the collapsible stroller includes a foldable frame assembly including a top frame pivotably coupled to a bottom frame such that the top frame is allowed to pivot along a longitudinal plane of the foldable frame assembly. The foldable frame assembly can include first strut assemblies pivotably coupled to the bottom frame at respective angled joints. The angled joints can each include a first axis of rotation that is angled relative to the longitudinal plane such that the strut assemblies pivot towards the longitudinal plane as the top frame pivots towards the bottom frame for forming the collapsed configuration. In some embodiments, the foldable frame assembly further includes a suspension system that also can pivot towards the longitudinal plane when the foldable frame assembly forms the collapsed configuration.

A cart handle and a baby cart in which cart handle includes a fixed member; a handle body rotatable relative to the fixed member; an engagement part having a first portion that non-rotatably engages the handle body and slidably engages the handle body, and having a second portion that non-rotatably engages the fixed member; and an operation part that is actuated to alternately displace the engagement part to an unlocked position, wherein the second portion is not in engagement with the fixed member, thereby permitting rotation of the handle body relative to the fixed member, and displace the engagement part to a locked position, wherein the second portion engages the fixed member, thereby preventing rotation of the handle body relative to the fixed member.
