[0031] The present invention will be further described below in conjunction with the accompanying drawings:

[0032] like Figures 1 to 6 ,as well as Fig. 9 and Fig.10 As shown, a seat reversing structure includes a bottom support frame 1 and a seat assembly 2 connected to the bottom support frame 1, wherein the seat assembly 2 includes a seat plate 21 that can slide forward relative to the bottom support frame 1 and rotate relative to the bottom support frame 1 after sliding to a set position, and a backrest 22 is also connected to one side of the seat plate 21. The seat plate 21 can slide and rotate relative to the bottom support frame 1, so when the seat structure is installed on the frame 100, it can be installed backward and close to the push rod assembly 101 to ensure the safety and stability of the baby stroller. When the seat structure needs to be reversed, just pull the seat plate 21 forward and then rotate the seat plate 21. After the seat plate 21 rotates to the set position, slide the seat plate 21 back to its original position. Therefore, by sliding the seat assembly 2 forward, the push rod assembly 101 of the child stroller avoids interference with the rotation of the seat assembly 2, so that the seat assembly 2 can rotate. After the seat assembly 2 rotates to the set position, the seat assembly 2 slides back to the position close to the push rod assembly 101, so that the center of gravity of the seat assembly 2 is back, ensuring the safety of the child. The child stroller adopts the above-mentioned seat structure, which can not only realize the rotation reversal, but also ensure the safety and stability of the child stroller, achieving the best of both worlds.

[0033] like Figures 2 to 6 As shown, the bottom support frame 1 includes a base 11 and a sliding block 12 disposed in the base 11 and capable of sliding relative to the base 11 together with the seat plate 21. The sliding block 12 is rotatably connected to the seat plate 21 so that when the seat plate 21 and the sliding block 12 slide to a set position, the seat plate 21 can rotate relative to the sliding block 12 and the base 11. The seat plate 21 is rotatably connected to the sliding block 12, and when the seat plate 21 slides relative to the bottom support frame 1, the seat plate 21 slides relative to the base 11 together with the sliding block 12. When the sliding is in place, the seat plate 21 rotates relative to the sliding block 12 again to realize the rotation reversal of the seat assembly 2. Through the setting of the sliding block 12, the sliding movement of the seat assembly 2 is very smooth and reliable.

[0034] like Figures 2 to 6As shown, the base 11 is provided with a sliding groove 13, the sliding block 12 is arranged in the sliding groove 13, the sliding block 12 is provided with a through hole 14, and the seat plate 21 is provided with a connecting column 23 that is inserted into the through hole 14 and can rotate in the through hole 14. The connecting column 23 is penetrated in the through hole 14, so when the seat plate 21 is pulled, the connecting column 23 pushes the hole wall of the through hole 14 and slides with the sliding block 12. When sliding to the set position, the connecting column 23 rotates in the through hole 14 to realize the rotation reversal of the seat plate 21 relative to the bottom support frame 1, so that the seat assembly 2 can be firmly connected to the bottom support frame 1 and can move flexibly, and the design is very clever.

[0035] like Figure 2 , Figure 4 and Figure 5 As shown, a first return spring 15 is provided between the base 11 and the sliding block 12, which can push the seat plate 21 and the sliding block 12 to slide and return to their original position after the seat plate 21 is rotated to the right position. During operation, the seat plate 21 is pulled to slide forward relative to the bottom support frame 1, and then the seat plate 21 is pushed to rotate relative to the bottom support frame 1. When the seat plate 21 rotates to the set position, the seat plate 21 is released, and the first return spring 15 pushes the seat plate 21 to return to its original position, and the reversal of the seat assembly 2 is completed. Therefore, when rotating and reversing the seat assembly 2, only one pull, one turn, and one release are required, and the whole action is completed in one go, and the operation is very convenient and quick.

[0036] like Figures 5 to 8 As shown, the base 11 is provided with a snap-in groove 16, and the seat plate 21 is provided with a snap-in strip 24 that can slide into the snap-in groove 16 when it rotates to a set position. The cooperation between the snap-in strip 24 and the snap-in groove 16 enables the seat assembly 2 to be better positioned when it stays at a desired position.

[0037] like Figures 5 to 8 As shown, the bottom support frame 1 is provided with a protruding positioning seat 18 having a positioning edge 17, the seat plate 21 is provided with a supporting edge 25 that can abut against the positioning edge 17 to prevent the seat plate 21 from rotating, and the seat plate 21 is provided with a rotating edge 26 that is connected to the supporting edge 25 and can rotate around the positioning seat 18 when the supporting edge 25 is disengaged from the positioning edge 17. When the seat assembly 2 stays at the set position, the positioning edge 17 abuts against the supporting edge 25 to ensure that the seat plate 21 cannot rotate and ensure stable positioning. When rotation reversal is required, the seat plate 21 is pulled forward, and when the seat plate 21 moves to the position where the supporting edge 25 is disengaged from the positioning edge 17, the seat plate 21 can rotate around the positioning seat 18. Through the cooperation of the positioning edge 17 and the supporting edge 25, and the combination of the clamping groove 16 and the clamping strip 24, it can be ensured that the seat assembly 2 is firmly positioned at the set position.

[0038] like Figures 5 to 8As shown, the positioning edge 17 and the abutting edge 25 are straight edges, the rotating edge 26 is an arc edge, and the positioning seat 18 is provided with an arc edge 19 that can abut against the rotating edge 26 when the seat plate 21 rotates. The abutting cooperation between the arc edge 19 and the rotating edge 26 makes the seat plate 21 very stable when rotating.

[0039] like Figure 3 , Figure 5 and Figure 6 As shown, the sliding block 12 is provided with a slot 41, the base 11 is provided with a latch 42 which can slide therein and can engage or disengage with the slot 41, the latch 42 is provided with an exposed operating handle 43, and a second reset spring 44 which can push the latch 42 to reset is also provided between the latch 42 and the base 11. When rotation reversal is required, the operating handle 43 is pulled first to disengage the latch 42 from the slot 41. Only after the latch 42 is disengaged from the slot 41 can the seat plate 21 be pulled to slide relative to the bottom support frame 1. Therefore, the latch 42 plays the role of a second lock to avoid sliding of the seat plate 21 due to misoperation, thereby ensuring safety.

[0040] like Figures 5 to 8 As shown, the base 11 is provided with a strip hole 5 that can cooperate with the outer wall of the connecting column 23 when the seat plate 21 slides, the lower side of the base 11 is provided with a strip groove 6, and the lower end of the connecting column 23 is connected with a connecting piece 7 that protrudes from the outer side wall of the connecting column 23 and can slide with the groove wall of the strip groove 6. The connecting column 23 slides along the hole wall of the strip hole 5, and the outer wall of the connecting piece 7 also slides along the groove wall of the strip groove 6, so that the sliding of the seat plate 21 is very smooth.

[0041] like Fig. 9 and Fig.10 As shown, a baby stroller comprises a frame 100 , to which the seat structure as described above is connected, and the frame 100 is connected to the bottom support frame 1 . Fig. 9 and Fig.10 The schematic diagram of the seat structure being installed on the frame 100 is shown. When the seat assembly 2 is reversed, the seat plate 21 is first pulled forward, and then the seat plate 21 is pushed to rotate 180 degrees to the set position, and then the seat plate 21 is slid back to its original position. At this time, the rotation reversal of the seat assembly 2 is completed, and the operation is very convenient and quick. When pushing the baby stroller, the user can face the same direction as the child in the seat structure, or face the child after the seat structure is reversed.
