The transmission assembly 5 further includes a second elastic restoring member 52 acting on the transmission rod 51 for restoring, wherein the second elastic restoring member 52 is a spring, one end of which acts on the transmission rod 51, and the other end of which acts on other components of the seat assembly 21, so that the transmission rod 51 can be restored, and the locking pin 31 can be restored under the action of the first elastic restoring member 33. In the preferred embodiment, a transmission rod 51 corresponds to two sliding slots 410, and the two sliding slots 410 are symmetrically arranged and are matched with two ends of a sliding pin 510. In another embodiment, please refer to fig. 6 and 7, the operating member 41 is composed of a driving block 411 engaged with the transmission rod 51, and a rotating buckle 412 sleeved outside the driving block 411, and the sliding slot 410 is opened on the driving block 411. During assembly, after the driving block 411 is sleeved at the near end of the transmission rod, the sliding pin 510 penetrates through the sliding groove 410, and the rotating buckle 412 is sleeved outside the driving block 411, so that the sliding pin is prevented from being separated, and the assembly is convenient.

In one embodiment, the seat assembly 21 has, in addition to the support tube 210 arranged in the width direction thereof, a symmetrically arranged seat plate 211 connected by the support tube 210. The seat plate 211 is provided with a convex column for the supporting tube 210 to penetrate and sleeve, thereby improving the connection strength. The locking pin 31 and the first elastic restoring piece 33 are arranged in the seat plate 211, and the two transmission rods 51 are arranged in the support pipe 210 and partially extend into the seat plate 211 to be connected with the locking pin 31 to realize the force transmission. And the transmission component 5 is covered, so that the appearance is simpler. The driving rod 51 is provided with a first kidney-shaped hole 511 for accommodating the second elastic reset piece 52, the supporting tube 210 is provided with a first pin 53 passing through the first kidney-shaped hole 511, and the first pin 53 is fixed, so that the driving rod 51 can compress the second elastic reset piece 52 when sliding to prepare for subsequent reset.

In one embodiment, the seat assembly 21 has lugs 212 connected to the backrest assembly 22 at both sides in the width direction thereof, the backrest assembly 22 has rotating seats 220 connected to the lugs 212, and the rotating seats 220 are disposed at opposite inner sides of the lugs 212, and opposite outer sides of the lugs 212. The adapters 23 are disposed on opposite outer sides of the lugs 212 to facilitate coupling with the frame 1 and to expand the width dimension of the seat assembly 21. In one embodiment, an angle adjusting mechanism for adjusting the included angle between the seat assembly 21 and the backrest assembly 22 is disposed between the rotary seat 220 and the lug 212 to achieve the unfolded positioning of the backrest, which is convenient for children to sleep on or lie down, and specifically, the angle adjusting mechanism may be a plurality of lock grooves disposed on the lug 212 and a lock pin slidably disposed in the backrest assembly 22, and the lock grooves are mutually matched with the lock pin, and in a combined state, the rotation of the backrest assembly relative to the lug 212 is limited to achieve the multi-angle positioning.

Referring to fig. 5, 10-13, in one embodiment, the distal end of the driving rod 51 is provided with a protrusion 515 protruding radially from the seat plate 211, and the protrusion 515 may be formed by extending the driving rod 51 itself radially. In another embodiment, an L-shaped stop 514 is fixedly mounted on the distal end of the transmission rod 51, the protrusion 515 is a portion of the L-shaped stop 514, and the guiding hole 512 is formed on the L-shaped stop 514, so that the transmission rod 51 has a cylindrical shape and is convenient to assemble. The rotating seat 220 has a limiting portion 221 which cooperates with the protrusion 515 to limit the movement of the transmission rod 51, the limiting portion 221 radially extends from a portion of an outer edge of the rotating seat 220, a gap 516 for the protrusion 515 to extend into is formed between the lugs 212, and at this time, the protrusion 515 is clamped by the lugs 212 and the rotating seat 220, so that the transmission rod 51 cannot slide, and further, the unlocking operation cannot be performed. When the rotatable seat 220 is rotated to fully collapse the backrest module 22 against the seat module 21, the gap 516 disappears, allowing the protrusion 515 to slide, and the corresponding transmission rod 51 to slide, so that the operation of unlocking the first locking mechanism 3 can be performed after the backrest module 22 is fully collapsed, thereby defining a reasonable folding sequence and facilitating the operation.

In one embodiment, a U-shaped armrest 213 is rotatably connected between the two lugs 212, a second locking mechanism for limiting the rotation of the U-shaped armrest 213 is disposed between the U-shaped armrest 213 and the lugs 212, and the second locking mechanism may be ratchet grooves disposed on the lugs 212 and the U-shaped armrest 213, and a ratchet engaged with the ratchet grooves, and when the ratchet exits one of the ratchet grooves, the unlocking is completed.
