[0002] A child seat is a special seat for children in a car. Unlike adult seats, a child seat usually has protective structures on both sides of the child's head, waist and hips to protect the child from lateral impact. Existing child seats are usually installed on top of conventional adult seats in cars. On the one hand, this solution takes up a lot of space. On the other hand, after the child seat is installed, the area can only be used by children and adults can no longer use the seat, which brings a lot of inconvenience to the regular use of the car. Patent document No. CN204845612U discloses an integrated safety seat for adults and children, which rotates the adult seat so that the backrest used by the child is forward. This solution has great safety risks in actual use because it cannot protect the child from the side.

The first slide rod and the second drive screw 317 are arranged in parallel. The first slide rod slides relative to the child body 101. The end of the first slide rod is fixed to the slider. The slider is hinged to the inner end of the first connecting rod 304.

[0110] Example 2

[0111] Compared with Example 1, this embodiment also includes the following distinguishing technical features:

[0112] 5 and 6 , the folding assembly includes a scissor frame 307 , a pusher 308 , a second side wing frame 312 , a second connecting rod 309 and a first driving screw 310 ;

[0113] The scissors frame 307 includes two clamping rods 3071 , and the middle portions of the two clamping rods 3071 are hinged to the child body 101 through a first rotating shaft 3072 ;

[0114] The pushers 308 are respectively provided on both sides of the scissors frame 307. The pushers 308 are longitudinally provided with strip holes 311. The ends of the two clamping rods 3071 are respectively slidably fitted in the strip holes 311 through sliding hooks.

[0116] In this solution, the two pushers 308 are respectively provided with strip holes 311 adapted to the two ends of the scissors frame 307. Therefore, when the scissors frame 307 is closed and unfolded, it will drive the pushers 308 to move toward the middle and both sides, that is, push the pushers 308 on both sides to move outward or inward. Since one of the pushers 308 is threadedly engaged with the first drive screw 310, when the first drive screw 310 rotates, it will drive the pushers 308 to move outward or inward, thereby realizing that one power member drives the two pushers 308 to move synchronously. The second side wing frame 312 has a first hinge point 3121 and a second hinge point 3122 distributed front and rear. The first hinge point 3121 is hinged to the child body 101, and the second hinge point 3122 is connected to the pusher 308 via a connecting rod. Therefore, when the pusher 308 moves, the connecting rod pushes the second hinge point 3122 to rotate about the first hinge point 3121, thus causing the second side wing frame 312 to swing about the first hinge point 3121.

The rotating gear 501 is connected to the child body 101. The first drive worm 502 is driven by a sixth motor 503. The first drive worm 502 drives the rotating gear 501 to rotate, which can achieve a one-way locking effect. Only the first drive worm 502 can drive the rotating gear 501 to rotate, and the rotating gear 501 cannot drive the first drive worm 502 to rotate in the opposite direction.

[0156] As shown in Figure 19, the upper base 601 and the lifting base 402 are coordinated through the rotation of the gear plate, and the first driving worm 502 rotates to drive the rotating gear plate 501 and the upper base 601 to rotate, thereby changing the horizontal direction of the child part 1. Specifically, in practice, the direction of the child part 1 can be swapped front to back to further improve the protection of the child and better resist forward impact.

[0166] The fourth linear drive member 604 can drive the pitch seat 602 to slide in the strip guide hole 603. Since the outer end of the strip guide hole 603 is tilted upward, when the pitch seat 602 is pulled forward, the front of the pitch seat 602 will tilt upward, and when the pitch seat 602 is pulled backward, the rear of the pitch seat 602 will tilt upward, thereby realizing the pitch action of the pitch seat 602.

[0167] It should be noted that the third linear driving member 414 and the fourth linear driving member 604 have the same structural principle.
