The folding operation of the utility model baby carriage is as follows:

rotating the rider 13 backward and downward, the first link 14 is pushed to rotate backward and downward and move downward (the first link lower side moves downward along the extending direction of the rear leg 11), so that the seat link 3 is pulled to rotate backward and downward and move backward relative to the rear supporter 22, and the rear supporter 22 is also driven to rotate backward and downward; meanwhile, because the lower side of the first linkage 14 moves downward along the extending direction of the rear leg 11, the rear side of the second linkage 15 is driven to rotate downward along the rear leg 11, so that the third linkage 4 is pulled by the second linkage 15 to rotate downward, and the front supporting piece 21 is pulled to rotate downward; meanwhile, the front side of the second linkage member 15 pulls the front leg 12 to rotate backwards to lean against the rear leg 11 (as shown in fig. 5, 6 and 7); until the rear foot 11, the front foot 12, the rider 13, the first linkage 14, the second linkage 15, the front support 21, the rear support 22, the seat linkage 3, and the third linkage 4 approach each other, the frame 1 is completely folded (as shown in fig. 8 and 9).

That is, the seat support 2 can be folded along with the frame 1 during the folding process, so that the overall folding operation of the stroller is simple; after the baby carriage is folded, all components of the carriage 1 and the seat supporting piece 2 are close to each other, so that the whole volume of the baby carriage is small; in addition, since the front support 21 and the rear support 22 of the seat support 2 are rotated downward and closed to be folded during the folding of the stroller frame 1, the overall size of the folded seat support 2 in the front-rear direction is small, and the overall size of the folded stroller in the front-rear direction is small; the whole volume after the baby carriage is folded is small, and the baby carriage is convenient to carry and store.

Preferably, the rear end of the front support 21 and the front end of the rear support 22 are rotatably connected to the rear leg 11 and/or the front leg 12, so that the upper end of the seat support 2 does not protrude out of the upper end of the folded frame 1 during folding, and the overall height of the folded stroller is not affected; thus, the overall height of the folded baby carriage is further reduced, namely the overall volume of the folded baby carriage is further reduced.

Preferably, the rear support 22 and the seat linkage 3 are provided with corresponding movement guide means. In this embodiment, the movement guide device includes a guide hole and a slide bar 31 respectively disposed at the lower ends of the plate-shaped rear support 22 and the seat link 3, one side of the slide bar 31 extends into the guide hole when the frame 1 is in the unfolded state, and the slide bar 31 moves outward along the guide hole during the folding process of the frame 1. In this embodiment, it is preferable that the lower end of the plate-shaped rear support 22 is provided with a guide portion 221, the guide portion 221 is provided with the guide hole therein, the rear end of the slide rod 31 is fixedly connected to the lower end of the seat link 3, and the front end of the slide rod 31 extends into the guide hole when the frame 1 is in the unfolded state. In order to prevent the slide rod 31 from being separated from the guide hole due to the excessive backward movement distance of the seat link 3 during the folding process, in this embodiment, the length of the guide portion 221 and the length of the slide rod 31 are set longer, and the front end of the guide portion 221 extends below the front support 21, in order to prevent the guide portion 221 from interfering with the front support 21 during the folding process, a hollow portion 211 (as shown in fig. 2 and 3) is disposed at the position where the guide portion 221 extends forward of the plate-shaped front support 21. Or, the guiding portion 221 is shorter and forms a sliding sleeve shape, when the frame is in the unfolded state, the front end of the sliding rod 31 penetrates through the sliding sleeve and then extends into the lower side of the front supporting piece 21, and the plate-shaped front supporting piece 21 is provided with a hollow portion at the corresponding position to avoid the hollow portion. That is, the moving guide device is disposed at the lower end of the seat supporting member 2 and the seat linking member 3, when the frame is in the unfolded state, the front side of the moving guide device extends into the lower portion of the front supporting member 21, and the front supporting member 21 is provided with a hollow portion at a corresponding position to avoid interference.

In other embodiments, the movement guide device includes a rail and a slider (not shown) disposed on the rear support 22 and the seat link 3, respectively. The movement guide means is provided to allow the seat linkage to move smoothly relative to the rear support 22.

When the rear supporter 22 of the seat supporter 2 is tubular, the front side of the seat link 3 may be tubular or rod-shaped and may extend into the tubular rear supporter 22 in a relatively back-and-forth movement manner, so that the movement guiding purpose may be achieved.

In this embodiment, the frame 1 further comprises a push handle 16, the lower side of the push handle 16 is pivoted to the upper side of the handle 13, so that in the unfolded state of the frame 1, the push handle 16 can extend the height of the handle 13 to facilitate the cart; and the push handle 16 can be rotated relative to the handle 13 so that the push handle 16 can be rotated closer to the handle 13 when necessary, thereby not affecting the overall height of the folded stroller. In other embodiments (not shown), the lower side of the push handle 16 can be connected to the upper side 11 of the stroller to move up and down, so that the overall height of the folded stroller can be reduced by moving the push handle 16 down.

The front lower part of the front foot 12 is connected with a front wheel 7, and the rear lower part of the rear foot 11 is connected with a rear wheel 8.
