As shown in fig. 1 to 10, a child seat pocket comprises a seat cushion component 1, a backrest component 2, a front armrest component 3, a mounting component 4 and a connecting rod 5, wherein the mounting component 4 is mounted and connected with a frame of a baby carriage; the two installation components 4 and the two connecting rods 5 are respectively arranged at two sides of the cushion component 1, the backrest component 2 and the front armrest component 3 in a bilateral symmetry manner; the mounting component 4 is coaxially and rotatably connected with the rear part of the corresponding front armrest component 3 and the lower part of the backrest component 2 from outside to inside in sequence, and the lower end of the mounting component 4 is rotatably connected with the rear part of the corresponding cushion component 1; the connecting rod 5 is located the place ahead of

installation component

4, 5 upper ends of connecting rod are connected with preceding handrail component 3 rotation that corresponds, 5 lower extremes of connecting rod rotate with the cushion subassembly 1 that corresponds and be connected. Wherein, the connecting rod 5, the cushion component 1, the mounting component 4 and the front armrest component 3 form a four-link mechanism.

When this children's seat pocket is in the expansion state, connecting rod 5 with preceding handrail component 3's rotation point is located preceding handrail component 3 with the front side of installation component 4's rotation point, connecting rod 5 with cushion component 1's rotation point is located cushion component 1 with the front side of installation component 4's rotation point, preceding handrail component 3 with installation component 4's rotation point is located cushion component 1 with the top of installation component 4's rotation point.

In this embodiment, a backrest adjusting mechanism is disposed between the backrest module 2 and the front armrest module 3 to achieve locking and positioning of the backrest module 2 at different angles of use. Since the backrest adjustment mechanism is a common mechanism in the art, the backrest adjustment mechanism of the present embodiment is only provided at a different position compared to the prior art, and therefore, the detailed description and the specific structural limitations are not repeated herein.

In this embodiment, a fold lock mechanism 6 is provided between the front armrest assembly 3 and the mounting assembly 4, and can be unlocked by tilting the backrest assembly 2 forward to reduce the angle with the seat cushion assembly 1. Because the connecting rod 5, the cushion component 1, the mounting component 4 and the front handrail component 3 form a four-link mechanism, the positioning of the four-link mechanism can be realized only by locking any one rotating point of the four-link mechanism, and the unfolding and locking of the four-link mechanism can be realized by locking the front handrail component 3 and the mounting component 4 through the folding and locking mechanism 6.

As shown in fig. 3 to 6, in the present embodiment, the specific structure of the folding locking mechanism 6 is: the folding locking mechanism 6 comprises a gear 6-1 capable of sliding left and right and a return spring 6-2, the mounting assembly 4 is provided with a first toothed slot 6-4 corresponding to the gear 6-1, the front handrail assembly 3 is provided with a second toothed slot 6-3 corresponding to the gear 6-1, and the return spring 6-2 is arranged between the gear 6-1 and the first toothed slot 6-4; the folding locking mechanism 6 is locked or not through whether the gear 6-1 is clamped in the first tooth groove 6-4 and the second tooth groove 6-3 at the same time or not.

As shown in fig. 3 to 7, the specific embodiment of releasing the lock of the fold lock mechanism 6 by the backrest module 2 being flipped forward to reduce the angle with the seat cushion module 1 is: the gear 6-1 is provided with a convex column 6-1-1, the front handrail component 3 is provided with a slotted hole 3-1 for the convex column 6-1-1 to penetrate through and slide left and right, and the backrest component 2 is provided with a guide groove 2-1 for the convex column 6-1-1 to insert and slide circumferentially; the side end of the guide groove 2-1 is provided with a guide inclined plane 2-1-1 for guiding the convex column 6-1-1 to slide out of the guide groove 2-1.

Preferably, two convex columns 6-1-1 are arranged on two sides of the gear 6-1 close to the end face of the backrest component 2; the slotted hole 3-1 and the guide groove 2-1 are two corresponding to the two convex columns 6-1-1. The design can improve the stability during unlocking operation and ensure that the gear 6-1 can move outwards smoothly.

Wherein, the convex column 6-1-1 is provided with a matching inclined plane 6-1-2 corresponding to the guiding inclined plane 2-1-1 of the guiding groove 2-1. The design can ensure that the convex column 6-1-1 smoothly slides out or into the corresponding guide groove 2-1 when the backrest component 2 rotates.

In this embodiment, the mounting assembly 4 is preferably a socket that is matched with the mounting seats on two sides of the frame of the stroller in an inserting manner, and the socket is provided with an inserting locking mechanism for locking the mounting seats. Since the inserting locking mechanism is a common mechanism in the art, the detailed description and the specific structural limitation are not required herein. The design can be convenient for the installation and the disassembly between the child seat pocket and the frame of the baby carrier.

The working principle of the utility model is as follows:

as shown in fig. 1, 2 and 8, when the folding locking mechanism 6 is in the locked state, the gear 6-1 is simultaneously engaged in the first tooth groove 6-4 and the second tooth groove 6-3, and at this time, the front armrest assembly 3 and the mounting assembly 4 are relatively fixed, and the four-bar linkage mechanism is in the locked state;

as shown in the A, B, C position in fig. 8, when the backrest assembly 2 is adjusted at different angles of use, the boss 6-1-1 of the gear 6-1 slides in the guide slot 2-1 of the backrest assembly 2; at this time, the folding locking mechanism 6 and the four-link mechanism are still in a locking state;

as shown in position D in fig. 8 and fig. 9, when the backrest module 2 is turned forward and the boss 6-1-1 slides out of the guide slot 2-1, the backrest module 2 pushes the gear 6-1 outward through the boss 6-1-1, and when the gear 6-1 completely enters the first tooth slot 6-4 and is disengaged from the second tooth slot 6-2, the folding locking mechanism 6 enters an unlocking state, at which time the front armrest module 3 and the mounting module 4 can rotate relatively, and the four-bar linkage mechanism is in a free state.

At this time, the backrest module 2 is continuously turned forward (if the seated child is not seated, the backrest module 2 cannot rotate forward), and the front arm module 3, the link 5 and the seat cushion module 1 are driven by the backrest module 2 to rotate forward and downward and fold, so as to complete the folding and folding of the four-link mechanism, as shown in fig. 10.

The connecting rod 5, the cushion component 1, the mounting component 4 and the front handrail component 3 form a four-link mechanism, and the four-link mechanism is unfolded and locked by locking the front handrail component 3 and the mounting component 4 through the folding locking mechanism 6. The backrest component 2 is independent relative to the four-link mechanism, so that when the backrest component 2 is forwards turned and unlocked, the cushion component 1 cannot be immediately turned forwards and downwards, the phenomenon that a seated child falls off from the cushion component 1 before completely leaving the seat is avoided, and the safety performance in use is improved.

The above is only a specific application example of the present invention, and the protection scope of the present invention is not limited in any way. In addition to the above embodiments, the present invention may have other embodiments. All technical solutions formed by using equivalent substitutions or equivalent transformations fall within the scope of the present invention.
