[0027] Two countersunk holes 12 are symmetrically inserted through both sides of the U-shaped block 4. A bolt 11 is rotatably fitted into each of the two countersunk holes 12. Two second receiving grooves 21 connected to the countersunk holes 12 are symmetrically provided on the inner side of the U-shaped block 4. An internally threaded cylinder 20 is slidably connected in the second receiving groove 21. The internally threaded cylinder 20 is threadedly fitted onto the outside of the bolt 11.

[0028] Two first limiting blocks 3 are symmetrically slidably connected on the first cushion 1. A first arc-shaped surface 8 and a slot 7 are provided on the two first limiting blocks 3. Two L-shaped blocks 6 that are adapted to the slot 7 are symmetrically fixed on the second cushion 5. A second limiting block 17 and a second arc-shaped surface 26 are provided in the U-shaped block 4. The second limiting block 17 is slidably connected in the arc-shaped groove 18, which facilitates the fixing of the first cushion 1 and the second cushion 5 after flipping, preventing the cushions from opening on their own after being folded, thus ensuring the firmness of the two cushions when folded and stored. The first cushion 1 and the second cushion 5 are connected by bolts 11 and internal threaded cylinders 20, which facilitates the disassembly of the first cushion 1 and the second cushion 5, making it convenient to use the first cushion 1 and the second cushion 5 separately, and also making it convenient to clean the first cushion 1 and the second cushion 5.

[0029] Working principle: When the seat cushion needs to be folded and stored, the lever 13 is moved upwards. The lever 13 causes the second limiting block 17 to rise, so that the second limiting block 17 retracts into the first storage groove 16. At the same time, the first spring 23 is compressed, thereby releasing the second limiting block 17 from its positioning position. Then, the second seat cushion 5 is flipped downwards, so that the second seat cushion 5 is stacked on the top surface of the first seat cushion 1. When flipping the second seat cushion 5, the L-shaped block 6 will contact the first arc-shaped surface 8 on the first limiting block 3. Under the guidance of the first arc-shaped surface 8, the second... As the seat cushion 5 flips downwards, it drives the first limiting block 3 to move, while the second spring 28 is compressed, causing the L-shaped block 6 to engage with the slot 7. When the L-shaped block 6 is engaged with the slot 7, the compressed second spring 28 returns to its original position. With the first limiting block 3, the slot 7, and the L-shaped block 6 all in place, the second seat cushion 5 is fixed to the top surface of the first seat cushion 1, thus completing the folding and storage of the seat cushion. When needed, the first limiting block 3 is moved, causing the L-shaped block 6 to disengage from the slot 7, releasing the first limiting block 3 from the second seat cushion. The second seat cushion 5 is positioned, and then it is flipped upwards, causing the positioning shaft 22 to slide within the arc-shaped groove 18. This allows the positioning shaft 22 to contact the second limiting block 17. Under the action of the second arc-shaped surface 26 of the second limiting block 17, the second limiting block 17 is driven to move upwards, causing it to retract into the first storage groove 16. Simultaneously, the first spring 23 is compressed. When the positioning shaft 22 passes under the second limiting block 17, the compressed first spring 23 returns to its original position, causing the second limiting block 17 to move out of the first storage groove 16. The inner part descends, limiting and fixing the positioning shaft 22, thereby fixing the angle of the opened second seat cushion 5. When it is necessary to disassemble the first seat cushion 1 and the second seat cushion 5, after folding and storing the second seat cushion 5, rotate the two bolts 11 respectively. When the bolts 11 rotate, the internal threaded cylinder 20 is pulled out from the positioning groove 19 and put into the second storage groove 21. At this time, the positioning shaft 22 is located on one side of the guide groove 15. Then push the first limiting block 3 so that the first limiting block 3 separates from the L-shaped block 6. Then the second seat cushion 5 can be taken out upward.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
