[0027] The present application provides a foldable baby stroller, comprising movable front legs, rear legs and a push handle, wherein the lower ends of the front legs and the rear legs are provided with walking wheels, the upper ends of the front legs, the upper ends of the rear legs and the lower end of the push handle are respectively provided with hinged ends that cooperate with each other to rotate, a seat plate for placing the baby is provided between the front legs and the rear legs, and the left and right sides of the seat plate are respectively rotatably connected with sliding sleeves, and the sliding sleeves are slidably mounted on the rear legs, the rotatable connection between the seat plate and the front legs, or the sliding sleeves are slidably mounted on the front legs, the rotatable connection between the seat plate and the rear legs.

[0028] Implementation example Figures 1 to 4 As shown, a foldable baby stroller includes mutually hinged front legs 1, rear legs 2, and a push handle 3. The lower ends of the front legs 1 and rear legs 2 are respectively provided with running wheels. The upper ends of the front legs 1, the upper ends of the rear legs 2, and the lower end of the push handle 3 are respectively provided with hinged ends that cooperate and rotate with each other to form a hinge structure 4. A seat plate 5 for placing a baby is provided between the front legs 1 and the rear legs 2. The seat plate 5 has sliding sleeves 6 rotatably connected to the left and right sides. The sliding sleeves 6 are slidably mounted on the rear legs 2, and the seat plate 5 is rotatably connected to the front legs 1; alternatively, the sliding sleeves 6 are slidably mounted on the front legs 1, and the seat plate 5 is rotatably connected to the rear legs 2. In this embodiment, the sliding sleeves 6 are provided on the left and right sides of the rear portion of the seat plate 5 and are mounted on the rear legs 2. The left and right sides of the front portion of the seat plate 5 are rotatably connected to the front legs 1 via connecting members 7.

[0029] Furthermore, the rear leg 2 is provided with a first limiting portion 2.1 near the hinge end for limiting the movement of the sliding sleeve 6 toward the hinge end, so as to limit the flipping range of the seat plate 5.

[0030] Furthermore, a rotating shaft 5.1 is provided at the bottom of the seat plate 5 and is rotatably connected to the sliding sleeve 6. A fixing portion 5.2 for mounting the rotating shaft 5.1 is formed at the bottom of the seat plate 5. The rotating shaft 5.1 is rotatably mounted in the fixing portion 5.2.

[0031] Specifically, the connecting member 7 is provided between the seat plate 5 and the front leg 1 , with one end of the connecting member 7 fixedly connected to the front leg 1 and the other end rotatably connected to the seat plate 5 .

[0032] Furthermore, an auxiliary plate 8 for placing the baby's legs is provided at the front end of the seat plate 5. The auxiliary plate 8 is hinged to the lower end of the seat plate 5 and can be flipped and stored at the bottom of the seat plate 5.

[0033] Specifically, the auxiliary plate 8 is provided with a second limiting portion 8.1 at the hinge. When the auxiliary plate 8 is flipped and unfolded to be parallel to the seat plate 5, the second limiting portion 8.1 abuts against the front end of the seat plate 5 to limit the position, thereby preventing the auxiliary plate 8 from flipping upward excessively.

[0034] Furthermore, a limit frame 9 is provided on the upper portion of the seat plate 5, which is rotatably connected to the push handle 3 or the front leg 1. The limit frame 9 is used to limit the baby's movement space and prevent the baby from falling from the stroller. The limit frame 9 extends forward to form a storage plate 9.1 for placing items.

[0035] Working principle: When folding and storing, the push handle 3 is rotated toward the rear leg 2, and the rear leg 2 and the front leg 1 are rotated closer to each other, while the sliding sleeve 6 slides toward the lower end of the rear leg 2 and drives the seat plate 5 to flip and store.

[0036] Those skilled in the art should understand that the various technical features of the above-described embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the various technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0037] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, all of which fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
