The front end of the folding plate 32 is hingedly connected to the fourth frame 6. The first frame 3, the second frame 4, the third frame 5 and the fourth frame 6 together constitute the frame part of the baby carriage, which are connected together by hinges. Through simple operations, the baby carriage can be easily folded and unfolded, which is convenient for storage and carrying, and greatly reduces the burden of carrying. The folding plate 32 includes a first connecting plate 9 and a second connecting plate 10. The first connecting plate 9 is hinged to the lower end of the fourth frame 6, and the second connecting plate 10 is hinged to the lower end of the second frame 4. The first connecting plate 9 and the second connecting plate 10 are frame-shaped, and a plurality of spaced welding rods 26 are arranged inside the two. As shown in the attached figure Figure 4 As shown, first connecting rods 27 are provided at both ends of the first connecting plate 9, and second connecting rods 28 are provided at both ends of the second connecting plate 10. The first connecting rod 27 and the second connecting rod 28 are hinged, so that when the baby carriage is folded, the first connecting plate 9 and the second connecting plate 10 can be relatively folded, further reducing the volume after folding, and after unfolding, items can be placed above the first connecting plate 9 and the second connecting plate 10, which has a certain storage function. Fixed plates 11 are provided at both ends of the first connecting rod 27, and the fixed plates 11 are in contact with the second connecting rod 28. The setting of the fixed plate 11 can limit the first folding plate 32 and the second folding plate 32 after unfolding, so that the two can maintain stability and strength after unfolding. A rotating assembly 17 is provided between the upper end of the fourth frame 6 and the lower end of the third frame 5, and the upper end of the fourth frame 6 is rotatably connected to the lower end of the third frame 5 via the rotating assembly 17. As shown in the attached Figure 3As shown, the rotating assembly 17 includes a first connecting block 7 and a second connecting block 8 that are hinged to each other; a sub-buckle 18 is fixed on the first connecting block 7, and a mother buckle 20 is fixed on the second connecting block 8, and the mother buckle 20 is buckled and connected with the sub-buckle 18. When unfolded, the buckle on the sub-buckle 18 can be buckled with the mother buckle 20 to support the third frame 5 and the fourth frame 6. When folding is required, it is only necessary to remove the buckle on the sub-buckle 18 that is buckled with the mother buckle 20, which is convenient and simple to operate. A first connecting hole group 19 is provided on the second connecting block 8, and a first screw 21 is provided in the first connecting hole group 19. The second connecting block 8 is fixedly connected to the fourth frame 6 via the first screw 21. One end of the first connecting block 7 extends to one side and is provided with a first hinge hole 24; one end of the second connecting block 8 extends to one side and is provided with a second hinge hole 25; the first hinge hole 24 is hinged with the second hinge hole 25, so that the third frame 5 and the fourth frame 6 can rotate relative to each other, further increasing the folding flexibility of the baby carriage. An air cushion 2 is provided on the lying board 1, and the setting of the air cushion 2 can increase the comfort of the baby's riding. At the same time, the air cushion 2 has a certain buffering effect and can effectively protect the baby. The air cushion 2 can effectively absorb the vibration caused by uneven road surface and reduce the discomfort of the baby. Whether it is a short or long distance trip, it can ensure the comfort of the baby and reduce crying and discomfort. The air cushion 2 is connected with a strap 13, and the setting of the strap 13 can conveniently fix the baby on the air cushion 2 to increase safety. An air nozzle 14 is provided at the rear end of the air cushion 2, and the air can be inflated into the air cushion 2 through the air nozzle 14 to adjust the hardness of the air cushion 2. Universal wheels 16 are provided at the lower ends of the fourth frame 6 and the second frame 4. By providing the universal wheels 16, the baby carriage can be conveniently moved. Preferably, the air cushion 2 is in a semi-enclosed shape, which can better wrap the baby and increase the comfort of the baby. Preferably, a sunshade 15 is provided on the lying board 1, and the sunshade 15 is located on the inner side of the air cushion 2. The setting of the sunshade 15 can block the sunlight and protect the baby from direct sunlight.

[0023] How it works

[0024] First, make sure that the baby and other items have been removed from the stroller. Since the fourth frame 6 intersects and is hinged with the second frame 4, the fourth frame 6 can be folded backwards first to fit with the first frame 3. Due to the setting of the rotating assembly 17, when unfolding, the buckle on the sub-buckle 18 is buckled with the mother buckle 20, which plays a supporting role for the third frame 5 and the fourth frame 6, so that the third frame 5 and the fourth frame 6 can be firmly connected. When folding, remove the buckle on the sub-buckle 18 that is buckled with the mother buckle 20, and the fourth frame 6 is folded backward, which can drive the second frame 4 and the third frame 5 to fold toward the first frame 3, so that they are parallel to or close to the lying board 1. When folding the frame, the first connecting plate 9 and the second connecting plate 10 will also be relatively folded due to the hinge. When unfolding, the fixing plate 11 can provide a limit for the first connecting plate 9 and the second connecting plate 10, so that the two are firmly in the same plane. The universal wheels 16 can be folded up under the drive of the second frame 4 and the third frame 5 for easy storage and carrying. The air cushion 2 can be inflated and deflated through the air nozzle 14, thereby reducing the volume. At the same time, the sunshade 15 can also be folded and stored. The folded baby stroller is shown in the attached figure. Figure 2 shown.

[0025] In summary, the utility model can be folded and unfolded quickly, and has the advantages of small storage space, high portability, and safety and reliability.
