Abstract: A collapsible stroller includes a stroller frame, at least one hinge mechanism, a wheel, and a swivel mechanism. The stroller frame is moveable between a deployed position and a collapsed position. The hinge mechanism allows for movement of the stroller frame between the collapsed position and the deployed position. The swivel mechanism connects the wheel to the stroller frame. The swivel mechanism includes a vertical axle, a cam follower, and a cam. The vertical axle connects with the wheel and is rotatable with respect to the stroller frame about a vertical axis. The cam follower is fixed to the vertical axle. The cam includes a sloped cam surface at least partially surrounding the vertical axle. The sloped cam surface contacts the cam follower to move the cam follower along the sloped cam surface, which results in rotation of the vertical axle about the vertical axis.

Abstract translation: 折叠婴儿车包括婴儿车框架，至少一个铰链机构，轮子和旋转机构。 婴儿车框架可在展开位置和折叠位置之间移动。 铰链机构允许婴儿车框架在折叠位置和展开位置之间移动。 旋转机构将车轮连接到婴儿车框架。 旋转机构包括垂直轴，凸轮从动件和凸轮。 垂直轴与轮连接，并且可相对于婴儿车框架围绕垂直轴线旋转。 凸轮从动件固定在垂直轴上。 凸轮包括至少部分地围绕垂直轴的倾斜凸轮表面。 倾斜的凸轮表面接触凸轮随动件以沿着倾斜的凸轮表面移动凸轮从动件，这导致垂直轴围绕垂直轴的旋转。
