Stroller with smooth folding linkage and small folding volume

Abstract

The invention discloses a stroller with smooth folding linkage and small folding volume, comprising a frame comprising a push handle, a driver, a front foot, a rear foot, a first link, a second link and a third link. The lower end of the push handle is pivotally connected with the upper end of the driver, the lower end of the driver is pivotally connected with the rear end of the front foot, the front end of the rear foot, the upper end of the first connecting rod is pivotally connected with the push handle, the second connecting rod is pivotally connected with the driver, the upper end of thesecond connecting rod is pivotally connected with the lower end of the first connecting rod, the lower end is pivotally connected with the upper end of the third connecting rod, and the lower side ofthe third connecting rod is pivotally connected with the rear foot. The frame further includes a drawing-in structure for bringing the front foot closer to the rear foot relative to rotation during frame folding, one side of the drawing-in structure being connected to the front foot. When the push handle is rotate forward and downward, other components of the frame rotate together until the components rotate close to the rear foot, and the frame is fully folded, so that the folding linkage of the invention is smooth, the folding is easy and labor-free, and the volume after the folding is small.

Baby carriages generally include a frame with an unfolded state and a folded state, a frame locking mechanism that locks the frame in the unfolded state, and is respectively arranged on The wheels at the lower ends of the front and rear sides of the frame have different frame structures for different strollers. During the transition from the unfolded state to the folded state of the frame, that is, during the folding process of the frame, different frame structures will lead to different The folding experience and the different sizes of the folding volume, some strollers are not smoothly linked with the components of the frame during the folding process, so the folding process is particularly laborious; some strollers are very large after folding, which takes up a lot of space , some strollers will be smaller when folded
