The seat pocket assembly 5 has a forward use state facing away from the push rod assembly 13 and a reverse use state facing the push rod assembly 13 on the stroller frame, when the seat pocket assembly 5 is in the forward use state, the backrest part 53 is positioned at the rear part of the seat part 51, and the face of a child faces forward when the child sits on the seat part 51, as shown in fig. 1-3; when the seat bag assembly 5 is in the reverse use state, the backrest portion 53 is positioned at the front of the seat portion 51, and the child faces rearward when seated on the seat portion 51, as shown in fig. 6 and 7.

When the seat pocket assembly 5 is switched between the forward use state and the reverse use state, the seat pocket assembly 5 is only required to be integrally rotated around the first axis a relative to the stroller frame, as shown in fig. 3, 4 and 7, the seat pocket assembly 5 is not required to be disassembled and then installed, any part of the seat pocket assembly 5 is not required to be operated, the seat pocket assembly 5 is enabled to be rotated in the forward use state or the reverse use state, and the reversing operation of the seat pocket assembly 5 is facilitated.

The foot rest lever 52 has an operating state when the seat bag assembly 5 is in the forward and reverse use states. When the foot rest lever 52 is in the working state in the forward use state of the seat pocket assembly 5, the foot rest lever 52 is located at the front lower part of the seat part 51, the plane of the seat part 51 contacting with the buttocks of the child extends approximately along the horizontal direction, the plane of the foot rest lever 52 inclines forwards and extends from the top to the bottom, and the foot rest lever 52 is used for the foot of the child to step on. When the foot rest lever 52 is in the working state when the seat pocket assembly 5 is in the reverse use state, the foot rest lever 52 is located at the rear lower part of the seat part 51, the plane of the seat part 51 contacting with the hip of the child extends approximately along the horizontal direction, the plane of the foot rest lever 52 is inclined backwards and extends from the top to the bottom, and the foot rest lever 52 is used for the foot rest of the child to step on.

When the seat pocket assembly 5 is switched between the forward using state and the reverse using state, and the seat pocket assembly 5 rotates relative to the cart frame, the pedal rod 52 can keep the working state to rotate relative to the cart frame, a rotating track is formed after the pedal rod rotates, the rotating track is a virtual rotating body, all parts forming the cart frame are far away from the rotating body, and therefore the seat pocket assembly 5 cannot interfere with rod pieces of the cart frame when reversing operation is carried out, and reversing operation of the seat pocket assembly 5 is influenced.

Specifically, the front bracket 11 and the rear bracket 12 are both located on the inner side of the revolving body and spaced from the inner side surface of the revolving body by a distance. The rear bracket 12 on each side is fixedly provided with a connecting part 12a, the connecting part 12a extends from the connecting part with the rear bracket 12 to the left and right or the right and to the outer side of the cart frame, the sliding part 16 is rotatably connected with the connecting part 12a, so that the sliding part 16 and the push rod support rod 131a are both positioned on the outer side of the revolving body and are spaced from the outer side surface of the revolving body by a certain distance. In the present embodiment, the slider 16 is provided with the escape portion 16a recessed from the outer surface of the slider 16 toward the inside of the slider 16, the escape portion 16a is provided toward the inside of the stroller, and when the seat pocket assembly 5 is rotated relative to the stroller frame between the forward use state and the reverse use state, the foot lever 52 keeps the operating state to rotate about the first axis a past the escape portion 16a, that is, the rotation body passes the escape portion 16a, as shown in fig. 4 and 5. Front link 14, rear link 15, connecting portion 12a, push rod link 131b, and push rod transition lever 131c are all located below the lowermost end of the rotor.

The seat bag assembly 5 can be folded, when the seat bag assembly 5 is folded, the backrest part 53 rotates towards the direction of closing the seat part 51, the foot bar 52 rotates towards the direction of closing the seat part 51 to be in a folded state, and when the foot bar 52 is in the folded state, the plane of the foot bar 52 and the plane of the seat part 51 contacting with the hip of the child are close to each other and are approximately in a parallel state.

When the stroller is in the unfolded state, the rod members forming the stroller frame are unfolded relatively, and the position of the rod members is locked in the unfolded state through the locking mechanism, the seat pocket assembly 5 is in the unfolded state, and the forward using state and the reverse using state are provided on the stroller frame, and the seat pocket assembly 5 can rotate around the first axis a relative to the stroller frame to enable the seat pocket assembly 5 to be freely switched between the forward using state and the reverse using state, as shown in fig. 1 to 7.

When seat pocket subassembly 5 was in forward user state and reverse user state, the shallow frame homoenergetic carried seat pocket subassembly 5 and folds.

Specifically, when the stroller is folded in the forward use state of the seat pocket assembly 5, the footrest 52 is first rotated to the folded state with respect to the seat portion 51, and the backrest portion 53 is rotated in a direction to be close to the seat portion 51, thereby completing the folding of the seat pocket assembly 5. When the stroller frame is folded, the upper push rod 132 slides downwards relative to the lower push rod 131 to be close to the lower push rod 131, the push rod assembly 13 rotates forwards to be close to the rear support 12, when the push rod assembly 13 rotates, the sliding piece 16 slides upwards along the push rod assembly 13, the front support 11 is pulled to rotate backwards through the rear connecting rod 15 and the front connecting rod 14 to be close to the rear support 12, and all the rod pieces forming the stroller frame are close together. Finally, the upper cross rod 21 rotates around a second axis B relative to the front support 11 and the rear support 12, so that the folded seat pocket assembly 5 is close to the stroller frame; of course, a linkage structure may be provided between the front support 11, the rear support 12 and the upper cross bar 21, and when the front support 11 and the rear support 12 rotate relatively, the upper cross bar 21 may be driven to rotate relatively to the front support 11 and the rear support 12, so that the folded seat pocket assembly 5 is close to the stroller frame. The final fold is shown in figure 8.

When the seat pocket assembly 5 is folded under a reverse use state, the folding process of the seat pocket assembly 5 and the seat pocket assembly 5 under a forward use state firstly fold the seat pocket assembly 5, then fold the stroller frame, and finally enable the upper cross rod 21 to drive the seat pocket assembly 5 to rotate around the second shaft B relative to the front support 11 and the rear support 12, so that the folded seat pocket assembly 5 is close to the stroller frame and is finally folded as shown in fig. 9.

When the stroller is in a folded state, the rod pieces forming the stroller frame are closely drawn together, the components forming the seat pocket assembly 5 are closely drawn together, and the folded seat pocket assembly 5 and the folded stroller frame are closely drawn together, so that the foldable stroller is compact in structure, small in size, convenient to carry and store after being folded.

The above embodiments are merely illustrative of the technical ideas and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and implement the present invention, and not to limit the protection scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
