The seat assembly 4 includes a seat 41 and a backrest 42 , and the seat 41 and the backrest 42 are rotatably connected through a second shaft 43 .

The stroller has a forward use state and a reverse use state. When the stroller is in the forward use state, the child sits on the seat 41 with the face facing the direction of the front wheel 32, as shown in Figures 1 to 3. When the stroller is in a reversed use state, the child sits on the seat 41 with the face facing the direction of the rear wheel 33 , as shown in FIG. 5 . The seat assembly 4 can be rotated relative to the front support plate 21 or the rear support plate 22 around the first axis 51 as a whole, so that the stroller can be converted between a forward use state and a reverse use state.

The stroller further includes a first locking mechanism. The first locking mechanism is arranged between the front support plate 21 and the seat 41 or between the rear support plate 22 and the seat 41 for locking the relative positions of the two. When the vehicle is in the forward use state and the reverse use state, the first locking mechanism is in the locked state. When the first locking mechanism is unlocked, the seat assembly 4 can be relative to the front support plate 21 or the rear support plate 22 around the first axis 51 as a whole. turn.

The stroller also includes a push rod assembly 6 that is rotatably connected to the seat 41 through a third shaft 52. When the push rod assembly 6 rotates relative to the seat 41 when the stroller is in a forward use state and a reverse use state, the push rod assembly 6 can drive the first push rod assembly 6 to rotate relative to the seat 41. A locking mechanism unlocks.

The push rod assembly 6 includes an upper push rod 61 and a lower push rod 62 , the lower part of the upper push rod 61 is rotatably connected with the upper part of the lower push rod 62 , and the lower part of the lower push rod 62 is rotatably connected with the seat 41 through the third shaft 52 .

The stroller further includes a second locking mechanism for locking the relative position of the lower bracket assembly 2 in the unfolded state. In this embodiment, the second locking mechanism is provided between the front support plate 21 and the rear support plate 22 for Lock the relative position of the two. The stroller also includes an unlocking mechanism for driving the second locking mechanism to unlock and fold the stroller. The unlocking mechanism includes an unlocking member 7 movably arranged on the front support plate 21 or the rear support plate 22. The unlocking member 7 is connected to the second locking member 7. Institutions cooperate.

When the stroller is in a forward use state, both the first locking mechanism and the second locking mechanism are in a locked state, the front support plate 21 and the rear support plate 22 are close to each other, and when the child sits on the seat assembly 4, the child faces away from each other. The push rod assembly 6 is shown in Figures 1 to 3.

When the stroller is in the reverse use state, the first locking mechanism and the second locking mechanism are also in the locked state, the front support plate 21 and the rear support plate 22 are close to each other, and when the child sits on the seat assembly 4, they can turn their backs to each other. The push rod assembly 6 , as shown in FIG. 5 , may also face the push rod assembly 6 .

When the stroller is switched from the forward use state to the reverse use state, after first unlocking the lock between the push rod assembly 6 and the seat 41, the push rod assembly 6 is turned forward relative to the seat 41 around the third axis 52, The first locking mechanism is driven to unlock gradually, and when the push rod assembly 6 is rotated forward by a certain angle, the first locking mechanism is unlocked, as shown in FIG. 4 .

After the entire body formed by the seat assembly 4 and the push rod assembly 6 is rotated about the first axis 51 by about 180 degrees relative to the front support plate 21 or the rear support plate 22, the first locking mechanism is locked again, so that the push rod assembly 6 is directed towards the front wheel 32 Flip, the commutation operation is completed, as shown in Figure 5. Or when the whole body formed by the seat assembly 4 and the push rod assembly 6 rotates about 180 degrees relative to the front support plate 21 or the rear support plate 22 around the first axis 51 and the first locking mechanism is locked again, the push rod assembly 6 is moved toward the rear wheel 33 . The direction can also be reversed.

When the stroller is converted from the reverse use state to the forward use state, after the lock between the push rod assembly 6 and the seat 41 is unlocked, when the child faces the push rod assembly 6, the push rod assembly 6 is made to revolve around the third axis 52 Turn over the seat 41 in the direction of the front wheel 32; when the child is facing away from the push rod assembly 6, make the push rod assembly 6 turn around the third axis 52 relative to the seat 41 in the direction of the rear wheel 33, and the rest and the stroller are used from the positive state The same process is used to use state transitions in the reverse direction.

When the stroller is in a forward use state, the stroller can also be folded. When folded, after unlocking both the first locking mechanism and the second locking mechanism, the backrest 42 is turned forward to be close to the seat 41; After the upper push rod 61 is flipped backward and is close to the lower push rod 62, the push rod assembly 6 is turned down as a whole to be close to the lower bracket assembly 2, so that the front support plate 21 and the rear support plate 22 are relatively slid away. This embodiment The middle is that the rear support plate 22 slides backward away from the front support plate 21. When the rear support plate 22 slides backward, it drives the front bracket 23 and the rear bracket 24 to rotate relative to each other, so that the height of the stroller gradually decreases, the seat assembly 4, the push rod Assembly 6, the front bracket 23 and the rear bracket 24 are gradually moved closer to the bottom bracket assembly 1. The folding process is shown in Figure 6 until the components that make up the stroller are close together, and the final folding is shown in Figure 7. On each side of the left and right sides of the stroller, the front support rod 231 and the rear support rod 241 are accommodated in the accommodation cavity formed by the front and rear U-shaped rods 112. The folded baby stroller is flat and has a structure. Compact, small size, easy to carry and store.

The above-mentioned embodiments are only to illustrate the technical concept and characteristics of the present invention, and the purpose thereof is to enable those who are familiar with the technology to understand the content of the present invention and implement accordingly, and cannot limit the protection scope of the present invention with this. All equivalent changes or modifications made according to the spirit of the present invention shall be included within the protection scope of the present invention.
