[0033] It should be noted that, in one embodiment of the present invention, the inner protective shell assembly 0231 includes an inner protective shell U-shaped bending part 02311 and an inner protective shell connecting shaft 022. There are two inner protective shell connecting shafts 022. The upper and lower ends of the inner protective shell U-shaped bending part 02311 are respectively opened to accommodate holes for the inner protective shell connecting shaft 022 to pass through.

[0034] It should be noted that, in another embodiment of the present invention, the outer protective shell assembly 0230 includes an outer protective shell U-shaped bending part 02301, and the lower end of the outer protective shell assembly 0230 is connected to the base assembly 01 through the lower movable shaft assembly 028.

[0035] It should be noted that, in another embodiment of the present invention, the connecting rod folding mechanism 02 also includes a seat cushion flipping assembly 021, which is rotatably connected to the upper end of the inner protective shell U-shaped bending part 02311. When connected, the inner protective shell connecting shaft 022 passes through the hole set on the seat cushion flipping assembly 021.

[0036] It should be noted that in another embodiment of the present invention, the seat cushion flip assembly 021 is further provided with a flip sliding groove 0215, and the connecting rod folding mechanism 02 further includes a flip connecting plate 0224, a flip connecting plate sliding shaft 0223, and a flip inner protective shell connecting shaft 0212.

The flip connecting plate sliding shaft 0223 is located in the flip sliding groove 0215. During flipping, the flip connecting plate sliding shaft 0223 can move within the flip sliding groove 0215.

[0037] It should be noted that, in another embodiment of the present invention, the seat cushion flipping assembly 021 is also provided with a seat cushion connecting block 0211. The seat cushion flipping assembly 021 can be connected to the seat cushion assembly 03 through the seat cushion connecting block 0211, or it can be connected to other components through the seat cushion connecting block 0211 and then connected to the seat cushion assembly 03. The present invention does not impose any special restrictions.

[0038] It should be noted that, in another embodiment of the present invention, the connecting rod folding mechanism 02 further includes a seat cushion flip limit pin 0232, which is connected to the upper end of the outer shell assembly 0230 and is used to limit the flip angle of the seat cushion.

[0039] It should be noted that, in another embodiment of the present invention, the connecting rod folding mechanism 02 also includes a gas spring 0226, and a gas spring fixing shaft 0225 is respectively provided on the outer protective shell assembly 0230 and the inner protective shell assembly 0231.

Front hole 02292 is connected to a corresponding hole in inner housing assembly 0231 via connecting rod pivot 0227, while rear hole 02293 is connected to a corresponding hole in outer housing assembly 0230 via connecting rod pivot 0227. The parallelogram shape provides a certain amount of auxiliary force during operation, providing greater stability and strength than other shapes. This parallelogram connection ensures the stability of connecting rod folding mechanism 02 during use.

[0043] It should be noted that, in another embodiment of the present invention, a weight-reducing hole 02294 is further provided on the connecting rod assembly 0229. The weight-reducing hole 02294 is used to reduce the weight of the entire seat while ensuring the stability of the seat.

[0044] The movement principle of the connecting rod folding mechanism 02 of the present invention is as follows: stepping on the lifting pedal 0222 → the pawl part 0228 and the lock tooth seat 01210 slip (the lifting pedal 0222 drives the pawl part 0228 to rotate together, causing the pawl part 0228 to separate and slip from the lock tooth seat 01210) → gas spring adjustment → the lower end of the connecting rod folding mechanism 02 is unlocked. After unlocking, the lower end of the connecting rod folding mechanism 02 is perpendicular to the base assembly 01 and is in a folded state.
