[0024] The following describes the embodiments of the present invention in detail with reference to the accompanying drawings.

[0025] like Figures 1 to 8 As shown, a card-connecting and unlocking mechanism of a seat in this embodiment, the seat 3 is detachably connected to the first support rod 101, and the card-connecting and unlocking mechanism 31 includes: a connecting seat 311, a locking block 312 and a locking elastic member 313. The connecting seat 311 is arranged at the bottom of the seat 3, and the connecting seat 311 is provided with a first positioning groove 3110 for positioning the first support rod 101, the locking block 312 is slidably connected to the connecting seat 311, and the locking elastic member 313 is arranged on the connecting seat 311 for driving the locking block 312 to extend to lock the first support rod 101 in the first positioning groove 3110, and the locking block 312 is provided with an unlocking part 3121 for driving the locking block 312 to retract into the connecting seat 311 to unlock the first support rod 101. When the card-connecting unlocking mechanism of the present invention is in use, the locking block can be retracted into the connecting seat by toggling the unlocking part, so that the first support rod can be installed in the first positioning groove. After the external force is removed, the locking block is reset under the action of the locking elastic member, and then the first support rod is locked in the first positioning groove. The unlocking can be done by the ideal operation, which has the advantages of simple structure and easy operation.

[0026] In this embodiment, in order to improve the stability of the direct connection between the seat and the first support rod, second positioning grooves 31100 for positioning the first support rod 101 are provided at the bottom of the seat 3 and on both sides of the latching and unlocking mechanism 31.

[0027] In this embodiment, when the frame is folded, in order to enable the seat to follow, it needs to rotate relative to the first support rod, and the bottoms of the first positioning groove 3110 and the second positioning groove 31100 are arc-shaped.

[0028] In this embodiment, the rear portion of the seat 3 is provided with a first backrest rod 32 and a second backrest rod 33. The lower end of the first backrest rod 32 is rotatably connected to the seat 3. The first backrest rod 32 and the second backrest rod 33 are connected by a folding joint 34. The first backrest rod 32 and the second backrest rod 33 are provided with backrests made of textile material (not shown in the drawings).

[0029] In this embodiment, in order to improve comfort, footrests 35 are pivotally connected on both sides of the front of the seat 3, and an adjustment mechanism 36 for adjusting the angle of the footrest 35 relative to the seat 3 is provided between the seat 3 and the footrest 35, which can improve comfort.

[0030] The adjustment mechanism 36 includes: a first locking groove 3601 provided on the seat 3, a locking slider 361 that can slide axially in the first locking groove 3601 is slidably connected in the first locking groove 3601, a first positioning protrusion 362 is provided in the first locking groove 3601, the locking slider 361 is provided with a sliding groove 3610 that cooperates with the first positioning protrusion 362, the locking slider 361 is provided with a locking protrusion 3611, the footrest 35 is provided with a locking recess 301 for the locking protrusion 3611 to be embedded in it, a reset elastic member 364 is provided between the first locking groove 3601 and the locking slider 361, and the footrest 35 is provided with an unlocking button 363 for driving the locking slider 361 to slide along the sliding groove 3610 to achieve unlocking. When the adjustment mechanism is in use, by pressing the unlock button 363, the locking slider 361 can slide along the slide groove 3610 and then the locking slider 361 can completely enter the first locking groove 3601 (at this time, the locking protrusion 3611 is no longer embedded in the locking recess 301), so that unlocking can be achieved and the angle of the footrest relative to the seat 3 can be adjusted, which has the advantage of easy operation.
