A snapping structure is provided, which is configured to detachably mount a body to a support frame. The snapping structure includes a locking member movably disposed on the body and a positioning member disposed on the support frame and mated with the locking member. The locking member is movable to be locked to the positioning member, so as to mount the body to the support frame, or the locking member is movable to be unlocked from the positioning member, so as to separate the body from the support frame.

A foldable multifunctional baby stroller is provided. A locking mechanism is provided at the joint between an upper front beam, an upper rear beam and an upright column of a side frame to maintain the main frame in an unfolded state. In the locked state, only pulling the switch plate upward and then lifting the locking mechanism upward can realize the switch of the main frame from the unfolded state to the folded state. Pulling the switch plate upward and then pressing the locking mechanism downward can realize the switch of the main frame from the folded state to the unfolded state, and after the unfolded state and folded state are transformed, the locking mechanism will automatically enter the locked state without additional operations.

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.

The invention provides a wheel for a pushchair, the wheel comprising a an inner hub for connection to an axle, an outer rim for engaging the ground in use a plurality of spokes connected between the inner hub and the outer rim, wherein the spokes are flexible.

Systems and methods for identifying failed computing nodes are disclosed. An example system includes a plurality of computing nodes, where each computing node of the plurality of computing nodes includes, or has access to, at least one hardware processor. An example method includes generating a unique identifier particularly corresponding to a particular node. The example method also includes periodically updating a node record in a persistent storage location with the unique identifier, where the node record is associated with the particular node. The example method further includes accessing the persistent storage location at a first time and identifying a most recent update to the node record. The example method also includes determining that the most recent update to the node record occurred more than a threshold amount of time prior to the first time.
