[0002] As a common childcare tool, the portability of a stroller is crucial, making folding functionality a standard feature of modern strollers. Most foldable strollers on the market currently require multiple steps or latches to fold, a cumbersome process, especially inconvenient for caregivers holding infants. Furthermore, these strollers often fail to stand upright after folding, instead tipping over to the ground. This not only easily soils the stroller's cover but also forces the user to bend over to pick it up, increasing the burden of use.

[0003] Therefore, it is necessary to provide a new baby stroller frame that can fold and stand upright under its own weight to solve the above-mentioned technical problems. Utility Model Content

[0004] The technical problem solved by this utility model is to provide a baby stroller frame that can be folded and stand upright by its own weight, which can realize one-click self-weight folding, standing storage and one-hand reversing functions, significantly improving the convenience of operation and hygiene of use.

[0005] To solve the above-mentioned technical problems, the present invention provides a baby stroller frame that can be folded and stand upright under its own weight, comprising: two large joints, a front leg tube, and a rear leg tube. The front leg tube is hinged to the two large joints, and the rear leg tube is fixedly connected to the large joints. Folding joints are hinged to the sides of the two large joints that are close to each other. A common rear canopy tube is fixedly installed on the two folding joints. A common seat frame tube is hinged to the bottom of the two folding joints. The seat frame tube is hinged to the front leg tube and the rear leg tube. Reversing joints are connected to the sides of the two large joints that are far from each other. A common push handle tube is fixedly installed on the two reversing joints. A common front armrest is fixedly installed on the two reversing joints.

[0006] Preferably, the push handle tube is provided with a reversing button, which is used to control the locking of the reversing joint and the large joint after rotation.

[0007] Preferably, the rear canopy tube is provided with a folding wrench, which is used to control the locking of the folding joint and the large joint after rotation.

[0008] Preferably, both sides of the seat frame tube are connected by folding joint connecting flat irons. The top end of the folding joint connecting flat irons is hinged to the folding joint. The bottom end of the folding joint connecting flat irons is hinged to a rear leg connecting flat iron and a front leg connecting flat iron. The rear leg connecting flat iron and the front leg connecting flat iron are hinged to each other. The rear leg connecting flat iron and the front leg connecting flat iron are respectively hinged to the rear leg tube and the front leg tube. Both sides of the seat frame tube are connected by seat frame tube connecting flat irons. The seat frame tube connecting flat irons are hinged to the front leg connecting flat irons.

[0009] Compared with related technologies, the baby stroller frame that can fold under its own weight and stand upright provided by this utility model has the following beneficial effects:

[0010] This invention provides a baby stroller frame that can fold and stand upright under its own weight. By constructing a cleverly designed four-bar linkage and integrated joint layout, the baby stroller can automatically fold under its own weight after being unlocked, requiring only a single action to trigger, significantly simplifying the operation process and improving folding efficiency. The folded frame can stand stably on the ground due to its structural characteristics, not only preventing fabric parts such as the cover from coming into contact with the ground and getting dirty, but also allowing the user to easily carry it without bending over, greatly improving the convenience of storage and retrieval, as the front handle forms a natural handle in the folded state. In addition, the reversing mechanism integrated into the push rod supports quick one-handed operation, realizing a smooth and reliable switching of the pushing direction. Attached Figure Description

The self-weight foldable and upright baby stroller frame includes: two large joints 6, a front leg tube 15, and a rear leg tube 10. The front leg tube 15 is hinged to the two large joints 6, and the rear leg tube 10 is fixedly connected to the large joints 6. Folding joints 12 are hinged to the sides of the two large joints 6 that are close to each other. The same rear canopy tube 4 is fixedly installed on the two folding joints 12. The same seat frame tube 7 is hinged to the bottom of the two folding joints 12. The seat frame tube 7 is hinged to the front leg tube 15 and the rear leg tube 10. Reversing joints 5 are connected to the sides of the two large joints 6 that are far from each other. The same push handle tube 2 is fixedly installed on the two reversing joints 5. The same front armrest 11 is fixedly installed on the two reversing joints 5.

[0017] The push handle tube 2 is provided with a reversing button 1, which is used to control the locking of the reversing joint 5 and the large joint 6 after rotation.

[0018] The reversing button 1 releases the circumferential lock between the reversing joint 5 and the large joint 6 via an internal linkage or wire transmission mechanism. At this time, the user can push the push handle tube 2 forward or backward, causing the entire push handle assembly and the connected reversing joint 5 to rotate around the large joint 6, thereby realizing the reversing.
