As shown in Figures 1 to 8, the children's stroller includes a stroller frame 1 in unfolded and folded states, a front wheel assembly 2 arranged at the bottom front of the stroller frame 1, and a front wheel assembly 2 arranged on the stroller frame 1. The rear wheel assembly 3 at the bottom rear part, the first seat mechanism 5 and the second seat mechanism 6 that are detachably arranged on the stroller frame 1, the locking mechanism for locking the stroller frame 1 in the unfolded state .

The stroller frame 1 includes side brackets respectively located on the left and right sides of the stroller frame 1 and transverse connecting rods connected between the left and right side brackets.

The side support on each side all comprises front support 11, rear support 12, push rod 13 and connecting rod 14, and front support 11 is inclined upwards from front to rear, and rear support 12 is inclined upwards from back to front, and the top of front support 11 and The top of the rear support 12 is rotatably connected by the first shaft 41, the bottom of the push rod 13 is rotatably connected with the top of the rear support 12 by the second shaft 42, and one end of the connecting rod 14 is connected with the push rod 13 by the third shaft 43. Rotationally connected, the other end of the connecting rod 14 is rotatably connected with the top of the front bracket 11 through the fourth shaft 44, like this, a four-link is formed between the front bracket 11, the rear bracket 12, the push rod 13 and the connecting rod 14 mechanism. When the stroller is in the unfolded state, on the front support 11, the first shaft 41 is located below the fourth shaft 44, on the rear support 12, the first shaft 41 is located below the second shaft 42, and on the push rod 13 , the second shaft 42 is located below the third shaft 43 .

The transverse link comprises a first transverse link 15 whose two ends are respectively fixedly connected to the front supports 11 on the left and right sides, a second transverse link 16 whose two ends are respectively fixedly connected to the rear supports 12 on the left and right sides, The third horizontal connecting rod 17 whose two ends are fixedly connected with the push rods 13 on the left and right sides respectively.

The first seat mechanism 5 and the second seat mechanism 6 can be arranged on the cart frame 1 to use simultaneously, and when the first seat mechanism 5 and the second seat mechanism 6 were arranged on the cart frame 1 simultaneously, the second seat mechanism 6 is positioned at the bottom and the rear of the first seat mechanism 5, and at this moment, the stroller becomes a double stroller, as shown in Fig. 1 and Fig. 2 . Simultaneously, the first seat mechanism 5 and the second seat mechanism 6 can also be separately arranged on the stroller frame 1 for use, and like this, the baby stroller becomes a single child stroller, as shown in Fig. 3 and Fig. 4 . Both the first seat mechanism 5 and the second seat mechanism 6 can be installed on the cart frame 1 forwardly or reversely for use, when the first seat mechanism 5 and the second seat mechanism 6 are installed on the cart frame 1 at the same time , the first seat mechanism 5 and the second seat mechanism 6 need to be both forward or reverse, that is, children face the same direction when sitting in the first seat mechanism 5 and the second seat mechanism 6 .

A specific embodiment, the first seat mechanism 5 includes a first frame, and the second seat mechanism 6 includes a second frame 61, when the stroller frame 1 is in an unfolded state, and the first seat mechanism 5 and the second seat When the mechanism 6 is installed on the cart frame 1 at the same time, the first surrounding frame and the second surrounding frame 61 are arranged in parallel.

When the second seat mechanism 6 is installed on the stroller frame 1 and the child stroller is folded, the second seat mechanism 6 needs to be disassembled from the stroller frame 1, and then the stroller frame 1 is folded.

Only the first seat mechanism 5 is installed on the stroller frame 1, and when the child stroller is folded, the first seat mechanism 5 can be folded, and the stroller frame 1 can also be folded. Specifically, the first seat mechanism 5 includes a first upper frame 51 and a first lower frame 52 , and the lower part of the first upper frame 51 is rotatably connected with the upper part of the first lower frame 52 .

In this embodiment, the first seat mechanism 5 is detachably arranged on the lower part of the push rod 13 , and the second seat mechanism 6 is detachably arranged on the lower part of the rear bracket 12 .

The locking mechanism can be arranged between any two parts that are rotationally connected in the above-mentioned four-bar linkage mechanism. The stroller also includes an unlocking mechanism for driving the locking mechanism to unlock. The specific structures of the locking mechanism and the unlocking mechanism are not included in this document. The technical points to be protected by the patent can all adopt the structures in the prior art. In this embodiment, the unlocking mechanism adopts the unlocking drawstring 7, and the unlocking drawstring 7 extends along the left and right directions, and its left and right ends are respectively arranged on the front brackets 11 on the left and right sides, and by pulling the unlocking drawstring 7, the locking When the mechanism is unlocked, the baby stroller can be folded at the same time, so that it can be folded in one carry.

When the stroller is used as a double stroller and is in the unfolded state, the first seat mechanism 5 and the second seat mechanism 6 are all arranged on the stroller frame 1, and the first frame is parallel to the second frame, as Figure 1 and Figure 2 show.

When the stroller is folded in the state shown in Figures 1 and 2, first the second seat mechanism 6 is disassembled from the stroller frame 1 to separate the stroller frame 1 from the second seat mechanism 6; then fold When the first seat mechanism 5 is folded, the first lower surrounding frame 52 is turned upwards around the rotation connection point of the first lower surrounding frame 52 and the first upper surrounding frame 51 to close together with the first upper surrounding frame 51, as shown in Figure 5 and shown in Figure 6; then, pull up the unlocking drawstring 7, and the locking mechanism is unlocked. After the locking mechanism is unlocked, the push rod 13 cooperates with the first seat mechanism 5 to turn downwards and rearwardly around the second axis 42 under the action of its own gravity. The brackets 12 move closer together. During this process, the connecting rod 14 drives the front bracket 11 to flip backward around the first axis 41 and move closer to the rear bracket 12 until the rods that make up the stroller are close together, and finally folded as shown in Figure 7 and shown in Figure 8. When the stroller is folded, it can be folded in one hand, and during the entire folding process of the stroller, the front wheel assembly 2 and the rear wheel assembly 3 are always supported on the ground, so that the folding operation of the stroller is very convenient. At the same time, the folded child stroller has a compact structure and a small volume, and is easy to carry and store.
