The disclosure provides a noise reduction structure comprising a stroller frame, a supporting frame connected to the stroller frame, and a wheel mounted on the supporting frame, the supporting frame receive a force so that the wheel contacts a supporting surface to slide; and an elastic resetting member is arranged between the supporting frame and the stroller frame, the resetting member always has a tendency to bring the supporting frame to reset. The noise reduction structure of the disclosure has a simple structure and is suitable for baby strollers or hand carts. By additionally arranging a resetting member between the supporting frame and the stroller frame, the supporting frame always has a resetting tendency, that is, when the supporting frame is unloaded, the resetting member may suspend the wheel, so as to avoid noise caused by friction between the wheel and the supporting surface.

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 wheeled carrying apparatus includes a frame structure including a standing frame, a wheel mount carrying a wheel and pivotally connected with the standing frame, the wheel being rotatable relative to the first wheel mount about a wheel axis, a locking assembly including a wheel mount latch movably connected with the standing frame, the wheel mount latch being engaged with the wheel mount to rotationally lock the first wheel mount with respect to the standing frame, and disengaged from the wheel mount to unlock the wheel mount for rotation of the wheel mount to change an orientation of the wheel axis, an actuating assembly coupled to the wheel mount latch and including one or more linking part, and a release mechanism including an operating part provided on the frame structure that is operable to cause the actuating assembly to pull the wheel mount latch to disengage from the wheel mount.

A seating/lying support (7) includes at least two seating/lying support elements (7a, 7b, 7c, 7d) which are movably interconnected, and at least one bearing element (8.1, 8.2, 8.3, 8.4). The at least one bearing element (8.1, 8.2, 8.3, 8.4) is connected to the seating/lying support elements (7a, 7b, 7c, 7d) such that a movement of the seating/lying support elements (7a, 7b, 7c, 7d) relative to one another can be produced.

A stroller includes a foldable frame comprising carbon fiber. The frame is configured to removably connect to at least one of a stroller seat and an infant car seat. The stroller includes a plurality of wheels that support the frame, and a handle coupled to the frame. The stroller may include a suspension system including a leaf having a flexible cantilevered portion fixed at a first end thereof to the stroller frame. The cantilevered portion has a second, free end spaced from the frame. The cantilevered portion is configured to flex about the fixed end. The suspension system includes a damper disposed between the first and second ends of the cantilevered portion and the stroller frame. The damper is configured to compress and expand in response to flexing of the cantilevered portion. A wheel is connected to an underside of said cantilevered portion of the leaf.
