When a component is referred to as being "connected" to another component, it can be directly connected to the other component or intervening components may also be present. When a component is referred to as being "disposed on" another component, it can be directly on the other component or intervening components may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
Referring to fig. 1 to 5, an automatic folding stroller includes a rear foot assembly 10, a front foot assembly 20, a front foot coupling assembly 30, a rear foot coupling assembly 40, a seat assembly 50, a lower handle assembly 60, an upper handle assembly 70, a slider 80, and a connecting rod 90.
The upper handle assembly 70 is pivotally connected to the lower handle assembly 60. When the automatic folding stroller is in use, the upper handle assembly 70 is aligned with the lower handle assembly 60. The lower handle assembly 60 is pivotally connected to an end of the seat assembly 50 at a proximal end thereof remote from the upper handle assembly 70. The end of the lower handle assembly 60 remote from the upper handle assembly 70 is pivotally connected to the rear foot assembly 10 and the front foot assembly 20. The pivotal connection of the lower handle assembly 60 to the rear foot assembly 10 and the pivotal connection of the lower handle assembly 60 to the front foot assembly 20 coincide. The heel assembly 10 is the same length as the forefoot assembly 20. The other end of the seat assembly 50 is pivotally connected to one end of the rear foot connecting assembly 40. The rear foot attachment assembly 40 is pivotally connected to the slide block 80 at an end remote from the seat assembly 50. The middle of the rear foot connecting assembly 40 is rotatably connected with the rear foot assembly 10. The middle of the connecting rod 90 is sleeved on the sliding block 80 and can move along the sliding block 80, and the two ends are respectively connected with the end parts of the rear foot assembly 10 and the front foot connecting assembly 30 in a rotating manner. The connection point of the heel coupling assembly 40 to the heel assembly 10 is located between the connection point of the heel assembly 10 to the connecting rod 90 and the rotational connection point of the heel assembly 10 to the forefoot assembly 20. The other end of the forefoot coupling assembly 30 is rotatably coupled to the forefoot assembly 20. The seat assembly 50, the rear foot connecting assembly 40, the rear foot assembly 10 and the lower handle assembly 60 now constitute a four-bar linkage. While the heel coupling assembly 40, the forefoot coupling assembly 30, the forefoot assembly 20, and the heel assembly 10 constitute a dual-crank mechanism.
When the automatic folding baby carriage needs to be folded, the upper handle assembly 70 is unlocked firstly, and the carriage is unlocked by rotating the upper handle assembly 70 anticlockwise after being unlocked. The upper handle assembly 70 and the lower handle assembly 60 swing downwards clockwise along with gravity to start automatic folding, and as the seat assembly 50, the rear foot connecting assembly 40, the rear foot assembly 10 and the lower handle assembly 60 form a four-bar linkage mechanism, the rear foot connecting assembly 40, the front foot connecting assembly 30, the front foot assembly 20 and the rear foot assembly 10 form a double-crank mechanism, and the rear foot assembly 10 and the front foot assembly 20 have the same length, in the folding process, the rear foot assembly 10 is taken as a fulcrum, the center of gravity is at the upper handle assembly 70 and the lower handle assembly 60, and the front foot assembly 20 slides on the ground to be folded until being completely folded. When fully retracted, the upper handle assembly 70 is parallel to the lower handle assembly 60 and is flush with the rear foot assembly 10. During the folding process, the rear leg connecting assembly 40 rotates downward to drive the connecting rod 90 to slide on the sliding block 80, and the connecting rod 90 drives the front leg assembly 20.
Through the design, the whole folding process is automatically completed, and the folding is convenient.
Various other modifications and changes may be made by those skilled in the art based on the above-described technical solutions and concepts, and all such modifications and changes are intended to fall within the scope of the claims.
