When the stroller of the present invention is to be folded, i.e. the stroller frame is to be converted from the unfolded state to the folded state, the frame locking mechanism is released, then the push handle 11 is rotated forward and downward, the first link 15 is driven to move downward and the upper end of the first link 15 is rotated backward and downward, and the rider 12 is linked to rotate backward and downward to be close to the rear leg 14, and when the first link 15 moves forward, the front end of the second link 16 is driven to rotate forward, so that the lower end of the second link 16 rotates backward by taking the sixth pivot 161 as a rotation axis, thereby pulling the upper end of the third link 17 and the rear side of the fourth link 18 to rotate backward and downward, and when the third link 17 rotates backward and downward, the third link 17 also approaches to the rear leg 14 (as shown in fig. 2); in the folding process, when the fourth connecting rod 18 moves backwards, the front end of the fourth connecting rod pulls the front foot 13 to rotate backwards to be close to the rear foot 14, namely the front foot 13 and the rear foot 14 are relatively rotated to be close to each other; that is, as long as the rider is moved by rotation, other components are linked to rotate relatively until the push handle 11, the rider 12, the front foot 13, the first link 15, the second link 16, the third link 17 and the fourth link 18 are all close to the rear foot 14, and the frame 1 is fully folded (as shown in fig. 3), at this time, the whole volume of the folded frame 1 is small, so that the space is not occupied, and the storage and transportation are convenient.
The frame locking mechanism may be disposed between any two of the push handle 11, the rider 12, the front leg 13, the rear leg 14, the first link 15, the second link 16, the third link 17, and the pulling structure, to prevent the two from rotating relatively, and may be any known and feasible mechanism, and the unlocking mechanism may also be any known and feasible structure, and is not described herein because it is not an important point of the present invention.
In this embodiment, as shown in fig. 4, the frame 1 includes left and right side brackets 10, each of which includes the push handle 11, the rider 12, the front foot 13, the rear foot 14, the first link 15, the second link 16, the third link 17, and a pull-up structure, and the stroller further includes a seat 4 disposed between the side brackets 10. Preferably, the seat 4 is arranged to be foldable together with the folding of the frame close to the rear foot 14, thereby facilitating folding of the pushchair of the present invention.
The frame 1 further comprises a handle bar 110 with left and right ends respectively connected to the upper ends of the handle bars 11 of the left and right side brackets, and a link bar 180 with left and right ends respectively connected to the rear ends of the fourth links 18 of the left and right side brackets, wherein the handle bar 110 and the link bar 180 can make the frame 1 more stable. Preferably, the left and right side bracket fourth links 18 are integrally formed with the link rail 180.
In the above description, the front wheel assembly 2 is located at the front, the rear wheel assembly 3 is located at the rear, the push handle 11 is located at the upper side, the front foot 13 and the rear foot 14 are located at the lower side, and the side brackets 10 are located at the left and right sides.
