example 1:

as shown in fig. 1 to 5, a baby carriage which can move from an unfolded position to a folded position after a locking device is unlocked comprises a front connecting seat 1, a front assembly 2 is connected on the front connecting seat 1, the front assembly 2 comprises a steering rod 21 which can rotate relative to the front connecting seat 1, a front wheel 22 is connected at the lower part of the steering rod 21, a steering handle 23 is connected at the upper end of the steering rod 21, the baby carriage also comprises a rear support 3 which is provided with a front connecting part 31 and a rear connecting part 32, a rear wheel 4 is connected on the rear connecting part 32, a transmission mechanism 5 which can enable the front connecting part 31 to be close to the upper end of the front assembly 2 and enable the rear wheel 4 to be close to the front wheel 22 when the baby carriage is folded is arranged between the front connecting part 31 and the front connecting seat 1, a seat support 6 is connected on the rear support 3, the front side of the seat support 6 is rotatably connected with the rear support 3 around a first axis a, a transmission piece 7 is arranged between the rear side of the seat supporting piece 6 and the rear support frame 3, one end of the transmission piece 7 is rotatably connected with the seat supporting piece 6 around a second axis B, the other end of the transmission piece 7 is movably connected with the rear support frame 3, and when the baby carriage is folded, the transmission piece 7 slides backwards along the rear support frame 3 to enable the seat supporting piece 6 to be close to the rear support frame 3. The rear support frame 3 is connected with the front connecting seat 1 through the transmission mechanism 5, when the baby carriage is folded, the transmission mechanism 5 drives the front connecting part 31 on the rear support frame 3 to move to the position close to the upper end of the front component 2, at the moment, the rear wheel 4 is close to the front wheel 22, and in the moving process, the seat supporting piece 6 is driven by the transmission piece 7 sliding along the rear support frame 3 to be close to the rear support frame 3, so that the folding of the whole baby carriage is realized. The whole baby carriage has simple and compact structure and small volume after being folded. The locking device can adopt a traditional spline clamping structure or a bayonet clamping hole structure and the like, and the details are not repeated.

As shown in fig. 1 to 5, the transmission mechanism 5 includes an upper transmission rod 51 and a lower transmission rod 52, one end of the upper transmission rod 51 is rotatably connected to the front connecting seat 1 around a third axis C, and the other end is rotatably connected to the rear bracket 3 around a fourth axis D; one end of the lower transmission rod 52 is rotatably connected with the front connecting seat 1 around a fifth axis E, and the other end of the lower transmission rod is rotatably connected with the rear support frame 3 around a sixth axis F. Therefore, the front connecting seat 1, the upper transmission rod 51, the lower transmission rod 52 and the rear support frame 3 form a four-bar mechanism, and the movement of the baby carriage is flexible and smooth in the unfolding or folding process of the baby carriage.

The first axis A and the fourth axis D are collinear, so that the rear support frame 3, the seat supporting piece 6 and the upper transmission rod 51 are coaxially connected, and the locking device is arranged between the rear support frame 3 and the upper transmission rod 51, so that the compact structure and flexible folding of the baby carriage are ensured.

As shown in fig. 2 to 5, the back frame 3 is provided with a sliding block 8 capable of sliding along the back frame, and the transmission member 7 and the sliding block 8 are rotatably connected around a seventh axis G and movably connected to the back frame 3 through the sliding block 8. When the baby carriage is unfolded or folded, the transmission piece 7 slides along the rear support frame 3 through the sliding block 8, so that the seat supporting piece 6 is unfolded or folded smoothly.

As shown in fig. 2 to 5, a lower linkage 9 is further disposed between the lower transmission rod 52 and the sliding block 8, one end of the lower linkage 9 is rotatably connected to the middle of the lower transmission rod 52 around an eighth axis H, and the other end is rotatably connected to the sliding block 8 around a ninth axis I. When the baby carrier is folded, the lower transmission rod 52 in the motion process pushes the lower linkage rod 9, so that the transmission part 7 slides downwards along the rear support frame 3, the seat support part 6 is drawn close to the rear support frame 3 to realize linkage folding of the whole baby carrier, when the baby carrier is unfolded, the transmission mechanism 5 with a four-bar structure is unfolded, and in the process, the lower transmission rod 52 pulls the lower linkage rod 9, so that the transmission part 7 slides upwards along the rear support frame 3, so that the seat support part 6 is unfolded, linkage unfolding of the whole baby carrier is realized, the structural design is ingenious, and the unfolding or folding is flexible and smooth.

As shown in fig. 1 and 5, the back bracket 3 includes an outer shell 33 and an inner rod 34 fixedly connected to the outer shell 33, and the sliding block 8 is slidably connected to the inner rod 34. The sliding block 8 slides along the inner rod 34, so that the baby carriage can be unfolded or folded smoothly. Of course, a sliding groove (not shown) may be provided on the back frame 3, and the sliding block 8 is slidably connected in the sliding groove.

Example 2:

as shown in fig. 6 to 9, embodiment 2 differs from embodiment 1 in that:

the rear wheels 4 are arranged on two sides of the rear support frame 3, the transmission piece 7 is provided with a connecting position 71 used for connecting the hand push rod 10, and when the baby carriage is in the folding position, the transmission piece 7 moves to a position close to the rear connecting part 32, and the included angle a between the hand push rod 10 and the rear support frame 3 is smaller than 20 degrees. The connection position 71 is a plug hole for the hand push rod 10 to plug in. Due to the fact that the transmission piece 7 is rotatably connected with the sliding block 8, after the transmission piece 7 slides along the back support frame 3, the transmission piece 7 can rotate relative to the back support frame 3, and therefore the rotation of the transmission piece 7 also enables the connection position 71 to change the direction, the extending direction of the hand push rod 10 in the unfolding state of the baby carriage and the extending direction of the hand push rod 10 in the folding state of the baby carriage can change, so that the included angle a between the hand push rod 10 and the back support frame 3 in the folding state of the baby carriage is smaller than 20 degrees, the hand push rod 10 is close to the seat support 6 in the folding state of the baby carriage, the fact that the hand push rod needs to be detached in the folding state of the traditional baby carriage is changed, and the baby carriage is more compact. In addition, when the folding baby carriage is folded, the folding baby carriage can be pulled to walk by the hand push rod 10, and the folding baby carriage can be dragged on the ground, so that the folding baby carriage is more convenient to carry.

As shown in fig. 6 to 9, a backrest 20 is rotatably connected to the seat support 6 to be unfolded or folded with respect to the seat support, and a surrounding frame 30 is connected to the backrest 20 to be unfolded or folded with respect to the backrest. The enclosure 30 ensures the safety of the child and the backrest 20 ensures the comfort of the child. When the stroller is folded, the surround 30 can be rotated onto the backrest 20, the backrest 20 can then be rotated together with the surround 30 onto the seat support 6, and finally the push bar 10 can be brought closer to the backrest 20.
