The child seat pocket comprises a seat cushion assembly 1, a backrest assembly 2, a front armrest assembly 3, a mounting assembly 4 and a connecting rod 5, wherein the mounting assembly 4 and the connecting rod 5 are respectively arranged on two sides of the seat cushion assembly 1, the backrest assembly 2 and the front armrest assembly 3 in a bilateral symmetry mode, the mounting assembly 4 is sequentially and coaxially connected with the rear part of the corresponding front armrest assembly 3 and the lower part of the backrest assembly 2 from outside to inside in a rotating mode, the lower end of the mounting assembly 4 is rotatably connected with the rear part of the corresponding seat cushion assembly 1, the connecting rod 5 is positioned in front of the mounting assembly 4, the upper end of the connecting rod 5 is rotatably connected with the corresponding front armrest assembly 3, and the lower end of the connecting rod 5 is rotatably connected with the corresponding seat cushion assembly 1. Wherein the connecting rod 5, the cushion assembly 1, the mounting assembly 4 and the front armrest assembly 3 form a four-link mechanism.
When the child seat pocket is in the unfolding state, the rotation points of the connecting rod 5 and the front armrest assembly 3 are located on the front side of the rotation points of the front armrest assembly 3 and the installation assembly 4, the rotation points of the connecting rod 5 and the seat cushion assembly 1 are located on the front side of the rotation points of the seat cushion assembly 1 and the installation assembly 4, and the rotation points of the front armrest assembly 3 and the installation assembly 4 are located above the rotation points of the seat cushion assembly 1 and the installation assembly 4.
In this embodiment, a backrest adjusting mechanism is disposed between the backrest module 2 and the front armrest module 3, so as to realize locking and positioning of the backrest module 2 at different angles of use. Because the backrest adjusting mechanism is a common mechanism in the art, the present embodiment is only different from the prior art in the arrangement position, and therefore, the detailed description and the specific structural limitation are not repeated here.
In this embodiment, a folding locking mechanism 6 is provided between the front armrest assembly 3 and the mounting assembly 4, and the folding locking mechanism can be unlocked by reducing the angle between the backrest assembly 2 and the seat cushion assembly 1 by turning forward. Because the connecting rod 5, the cushion assembly 1, the mounting assembly 4 and the front armrest assembly 3 form a four-bar linkage mechanism, the four-bar linkage mechanism can be positioned only by locking any one rotation point of the four-bar linkage mechanism, and the unfolding locking of the four-bar linkage mechanism is realized by locking the front armrest assembly 3 and the mounting assembly 4 through the folding locking mechanism 6.
As shown in fig. 3 to 6, in this embodiment, the folding locking mechanism 6 has a specific structure that the folding locking mechanism 6 includes a gear 6-1 capable of sliding left and right and a return spring 6-2, the mounting assembly 4 has a first tooth groove 6-4 corresponding to the gear 6-1, the front armrest assembly 3 has a second tooth groove 6-3 corresponding to the gear 6-1, the return spring 6-2 is disposed between the gear 6-1 and the first tooth groove 6-4, and the folding locking mechanism 6 is locked by whether the gear 6-1 is simultaneously clamped in the first tooth groove 6-4 and the second tooth groove 6-3.
As shown in fig. 3 to 7, the specific embodiment of unlocking the folding locking mechanism 6 by turning the backrest module 2 forward to reduce the angle with the cushion module 1 is that the gear 6-1 has a boss 6-1-1, the front armrest module 3 has a slot 3-1 through which the boss 6-1-1 is inserted and slides left and right, the backrest module 2 has a guide groove 2-1 through which the boss 6-1-1 is inserted and slides circumferentially, and the side end of the guide groove 2-1 has a guide slope 2-1-1 through which the boss 6-1-1 is guided to slide out of the guide groove 2-1.
Wherein, the number of the protruding columns 6-1-1 is preferably two, and the protruding columns are arranged on two sides of the end face of the gear 6-1, which is close to the backrest component 2, and the number of the slotted holes 3-1 and the guide grooves 2-1 is two corresponding to the two protruding 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 enable the convex column 6-1-1 to smoothly slide out of or slide into the corresponding guide groove 2-1 when the backrest component 2 rotates.
In this embodiment, the mounting component 4 is preferably a socket that is in plug-in fit with the mounting seats on two sides of the stroller frame, and a plug-in locking mechanism for locking the mounting seats is arranged on the socket. Because the plug locking mechanism is a common mechanism in the art, the details and specific structural limitations are not repeated herein. The design can facilitate the installation and the disassembly between the child seat pocket and the baby carriage frame.
The working principle of the invention is as follows:
As shown in fig. 1, 2 and 8, when the folding locking mechanism 6 is in a locked state, the gear 6-1 is simultaneously clamped in the first tooth slot 6-4 and the second tooth slot 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 a locked state;
as shown in the A, B, C position in fig. 8, when the backrest module 2 is adjusted at different angles, the protruding column 6-1-1 of the gear 6-1 slides in the guiding slot 2-1 of the backrest module 2, and the folding locking mechanism 6 and the four-bar linkage mechanism are still in a locking state;
As shown in the D position in fig. 8 and in fig. 9, the backrest module 2 is turned forward, and when the boss 6-1-1 slides out of the guide groove 2-1, the backrest module 2 pushes the gear 6-1 outwards through the boss 6-1, and when the gear 6-1 completely enters the first tooth groove 6-4 and leaves the second tooth groove 6-2, the folding locking mechanism 6 enters the unlocking state, and at this time, the front armrest module 3 and the mounting module 4 can rotate relatively, and the four-link mechanism is in a free state.
At this time, the backrest assembly 2 is turned forward (if the seated child is not sitting, the backrest assembly 2 cannot be turned forward), and the front armrest assembly 3, the link 5 and the cushion assembly 1 are driven to rotate forward and downward and fold by the backrest assembly 2, so as to complete folding and folding of the four-bar mechanism, as shown in fig. 10.
The connecting rod 5, the cushion assembly 1, the mounting assembly 4 and the front armrest assembly 3 form a four-link mechanism, and the front armrest assembly 3 and the mounting assembly 4 are locked through the folding locking mechanism 6, so that the unfolding locking of the four-link mechanism is realized. The backrest component 2 is independent relative to the four-link mechanism, so that when the backrest component 2 is turned forwards and unlocked, the cushion component 1 cannot be turned forwards and downwards immediately, the phenomenon that a child is not completely separated from the cushion component 1 is avoided, and the safety performance in use is improved.
The foregoing is merely 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 embodiments described above, other embodiments of the invention are possible. All technical schemes formed by equivalent substitution or equivalent transformation fall within the scope of the invention.
