working principle:

When the child seat needs to be converted from the use state to the folded state, the first locking mechanism 7 is unlocked, and the backrest board 1 is pushed forward so that the backrest board 1 rotates around the rotating shaft 19 of the rotating joint until it is between the backrest board 1 and the seat board 2 When the angle of the seat pocket is smaller than the angle when the seat is in the sitting position, the boss 16 is driven to move forward to contact with the matching part 17 of the slider 12 and cooperate with the movement, and the movement of the boss 16 drives the slider 12 to slide so as to compress the elastic member 15 And the locking part 14 and the locking part 13 are separated to complete the unlocking of the second locking machine 8. At this time, the seat board 2 moves backwards to the stacked setting of the back board 1 and the footrest 6, and completes the child seat from the use state to the folded position. State conversion, when the child seat is in the folded state, the seat board 2 and the back board 1 can rotate relative to the seat plug 5, therefore, when the child seat is fixed on the children’s article, under the action of its own gravity, the child seat It will rotate downward around the seat plug 5, so that the extension direction of the child seat is consistent with the extension direction of the folded children's product.

When it is necessary to convert the child seat from the folded state to the use state, pull the backboard 1 upwards to make the backboard 1 rotate around the rotating shaft 19 around the rotating joint, and drive the boss 16 to move backward to the same position as the slider 12. Separated, the slider 12 slides under the elastic force of the elastic member 15, thereby driving the locking member 14 and the locking part 13 to cooperate and lock, completing the locking of the second locking mechanism 8, locking the first locking mechanism 7, and completing the child seat. The transition from the folded state to the used state.

When it is necessary to switch the child seat between multiple use states such as a sitting position, a semi-lying position and a full lying position, the boss 16 is always separated from the slider 12, that is, the second locking mechanism 8 is in a locked state, By adjusting the first locking mechanism 7 so that the first locking mechanism 7 is switched between multiple locking positions, the child seat seat can be switched between multiple use states such as a sitting position, a semi-reclining position, and a full reclining position. Specifically, when the backboard 1 is pulled backward so that the backboard 1 rotates to the next locked position around the rotating shaft 19 of the rotary joint, under the action of the swing rod 3, the seat board 2 moves forward, so that the backboard 1 and the The angle between the seat boards 2 becomes larger; when the back board 1 is pushed forward so that the back board 1 rotates around the rotating shaft 19 of the swivel joint to the previous locking position, under the action of the swing rod 3, the seat board 2 moves backward Move so that the angle between the backrest board 1 and the seat board 2 becomes smaller.
