A locking device (not shown in the figure) is also provided between the sliding member 14 and the push rod support rod 131 , for locking the relative positions of the sliding member 14 and the push rod 131 when the stroller is in the unfolded state.

The seat pocket assembly 2 includes a lower surrounding frame 21 and an upper surrounding frame 22, the upper part of the lower surrounding frame 21 is rotatably connected with the lower part of the upper surrounding frame 22, and the upper surrounding frame 22 is arranged on the sliding member 14, so that when the sliding member 14 is opposite to When the push rod 13 slides, the seat pocket assembly 2 can be driven to slide relative to the push rod 13 with the sliding member 14 synchronously.

In this embodiment, a specific structure of the cart frame 1 is given. Of course, the cart frame 1 is not limited to the above structure, as long as the cart frame 1 includes the push rod 13 and the sliding member described above. 14. The seat pocket assembly 2 is arranged on the sliding member 14. When the sliding member 14 slides relative to the push rod 13, the seat pocket assembly 2 can be driven to slide relative to the push rod 13 with the sliding member 14 synchronously.

Taking the stroller frame 1 in this embodiment as an example, when the stroller is in the unfolded state, the front support rod 111 and the push rod support rod 131 extend in the same straight line direction, and both extend obliquely from front to back and upward, and the rear support rod 121 extends downward obliquely from front to back, the vertical rod 15 extends in the up-down direction, and the connecting rod 16 extends in the front-rear direction; on the front bracket 11, the second shaft 32 is located in the front and below the first shaft 31; on the rear bracket 12, The fourth axis 34 is located behind the first axis 31; the third axis 33 is located behind the first axis 31; on the vertical rod 15, the third axis 33, the fifth axis 35 and the fourth axis 34 are from top to bottom Sequentially arranged, that is, the fifth shaft 35 is located in the area between the push rod 13 and the rear bracket 12; The rod support 132 is matched, and the push rod support 131 has an upper end opposite to the lower end. The lower enclosing frame 21 and the upper enclosing frame 22 extend along the same straight line, and both extend upwardly from front to rear, and the straight line where the lower enclosing frame 21 and the upper enclosing frame 22 are located is approximately in the same line as the straight line where the front support rod 111 and the push rod support rod 131 are located. parallel state. As shown in Figure 1 and Figure 2.

When the stroller is folded, push the push rod 13 backwards and downwards, the push rod 13 rotates backwards and downwards around the first axis 31 to be close to the rear bracket 12 , and passes through the rear bracket 12 , the push rod 13 and the sliding member 14 . The crank-slider mechanism formed between the vertical rod 15 and the vertical rod 15 drives the sliding member 14 to slide along the push rod support rod 131 from the lower end to the upper end. 14 Sliding makes the vertical rod 15 rotate, and the front bracket 11 is pulled by the connecting rod 16 to rotate backward around the first axis 31 to be close to the rear bracket 12; the sliding member 14 can also drive the seat in the process of sliding relative to the push rod support rod 131. The pocket assembly 2 slides synchronously relative to the push rod support rod 131 and moves closer to the rear bracket 12, that is, the seat pocket assembly 2 can be folded synchronously with the cart frame 1, and the folding process is shown in FIG. 3; The rods are close together, and the cart frame 1 is folded; the lower enclosure frame 21 is turned forward to be approximately horizontal, and an included angle is formed between it and the upper enclosure frame 22 toward the cart frame 1. If the included angle is less than 180 degrees, the seat pocket assembly 2 is also folded, and the entire stroller is folded. The final folding is shown in Figures 4 and 5.

In the folded state of the stroller, the front bracket 11 , the rear bracket 12 , the push rod 13 and the upper frame 22 are arranged in order from front to back and close together closely, and the push rod support rod 131 and the upper frame 22 are still approximately parallel to each other. status. The lower frame 21 extends in the front-rear direction. The height of the entire seat pocket assembly 2 on the stroller frame 1 is not higher than the highest position of the stroller frame 1. In this embodiment, the rear bracket 12 is used when the stroller is in a folded state. The rear support 122 is at the highest position, and the lower frame 21 is located below the top of the rear support 122 . The whole baby stroller is compact in structure and small in size after being folded, and is easy to carry and store.

Preferably, the upper frame 22 is detachably disposed on the sliding member 14, so that when the stroller is not used for a long time, the seat pocket assembly 2 can be disassembled from the stroller frame 1, and packaged and stored separately. Moreover, after the seat pocket assembly 2 is damaged, the seat pocket assembly 2 can be replaced with a new one when the cart frame 1 is not replaced, which can reduce the cost.

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