[0032] In this embodiment: when the parent-child baby carriage body 1 is traveling on an uneven road surface, the bumpy vibration generated by the wheels 4 will be transmitted to the chassis carrier 21 and the shock-absorbing seat 22. At this time, the shock-absorbing spring 1 23 can effectively absorb the vibration, reduce the bumpy feeling, and make the child ride more comfortably. At the same time, during the bumpy and vibration process, the distance between the parent-child baby carriage body 1 and the shock-absorbing seat 22 will also change accordingly. Then, through the cooperation of the fixed seat 24, the angle between the two sets of hinged support rods 25 can be forced to change accordingly, thereby squeezing the shock-absorbing springs 2 26 on both sides to deform, and driving the positioning slider 27 to slide in the positioning slide groove opened inside the shock-absorbing seat 22, so as to achieve further vibration absorption. Even if encountering potholes or raised ground, the impact of the impact force on the child's body can be minimized.

The surface of the flip gear 32 is meshed and connected with a flip rack 33, and a moving groove adapted to the flip rack 33 is opened inside the parent-child stroller body 1. A connecting block 34 is fixed between the top ends of the two groups of flip racks 33, and an electric push rod 35 is screwed between the connecting block 34 and the parent-child stroller body 1. Magnetic blocks 36 are fixed to the opposite ends of the two groups of guardrails 31, and the magnetic poles of the adjacent sides of the two groups of magnetic blocks 36 are opposite.

[0036] In this embodiment: when a child user needs to drive the parent-child stroller body 1, first let the child sit on the seat cushion 5, and then through the piezoelectric switch installed inside the seat cushion 5, the electric push rod 35 can be automatically started, and then the electric push rod 35 pulls the connecting block 34 to drive the flip racks 33 on both sides to slide in the moving groove opened inside the parent-child stroller body 1, and the flip gear 32 can be driven to rotate inside the parent-child stroller body 1. Through the rotation of the flip gear 32, the guardrail 31 can be driven to relatively flip in the make way channel opened inside the parent-child stroller body 1, and the magnetic blocks 36 fixed at the ends of the guardrail 31 are driven to approach and attract each other. When the two groups of magnetic blocks 36 are adsorbed together, the child sitting on the seat cushion 5 can be protected.

[0037] The working principle and use process of the utility model are as follows: when a child user needs to drive the parent-child stroller body 1, first let the child sit on the seat cushion 5, and then through the piezoelectric switch (not shown in the figure) installed inside the seat cushion 5, the electric push rod 35 can be automatically started, and then the electric push rod 35 pulls the connecting block 34 to drive the flip racks 33 on both sides to slide in the moving grooves opened inside the parent-child stroller body 1, and the flip gear 32 can be driven to rotate inside the parent-child stroller body 1. Through the rotation of the flip gear 32, the guardrail 31 can be driven to relatively flip in the yield channel opened inside the parent-child stroller body 1, and the magnetic blocks 36 fixed at the ends of the guardrail 31 are driven to approach and attract each other. When the two groups of magnetic blocks 36 attract each other, After being attached together, the child sitting on the seat cushion 5 can be protected. At this time, by starting the parent-child stroller body 1 to drive the wheels 4 to rotate, the driving fun of parent-child interaction can be experienced. The guardrail 31 can form an effective barrier on both sides of the child, greatly reducing the possibility of the child falling out of the parent-child stroller body 1, providing a solid safety guarantee for the child's safety, and preventing the child from falling in the parent-child stroller body 1 due to restlessness or vehicle shaking. In addition, for children, seeing the guardrail 31 around them will make them feel safer psychologically, so that they can play or rest more relaxedly and safely in the parent-child stroller body 1, giving the child enough psychological security during driving, and reducing the psychological burden of parents.

[0038] During driving, when the parent-child baby carriage body 1 is traveling on an uneven road surface, the bumpy vibrations generated by the wheels 4 will be transmitted to the chassis carrier 21 and the shock-absorbing seat 22. At this time, the shock-absorbing spring 1 23 can effectively absorb the vibrations, reduce the bumpy feeling, and make the child ride more comfortably. At the same time, during the bumpy and vibrating process, the distance between the parent-child baby carriage body 1 and the shock-absorbing seat 22 will also change accordingly. Then, through the cooperation of the fixed seat 24, the angle between the two sets of hinged support rods 25 can be forced to change accordingly, thereby squeezing the shock-absorbing springs 2 26 on both sides to deform, and driving the positioning slider 27 to slide in the positioning slide groove provided inside the shock-absorbing seat 22, so as to achieve further absorption of vibrations. Even if encountering potholes or raised ground, the impact force on the child can be minimized to the greatest extent. The impact of the child's body, and greatly improve the durability of the parent-child baby carriage body 1, greatly increase the bearing capacity of the chassis load-bearing frame 21, so that the parent-child baby carriage body 1 can withstand greater weight and pressure, not only can it adapt to the growth and changes of the child, but also can improve the service life of the baby carriage to a certain extent, reduce the possibility of damage to the chassis load-bearing frame 21 and other components, and reduce the frequency of repair and replacement of parts. The good shock-absorbing effect can make the parent-child baby carriage body 1 more stable during driving, thereby helping the parent-child baby carriage body 1 to maintain balance and reduce the risk of rollover. It can adapt to a variety of road conditions, whether it is a flat sidewalk, a rugged path or a different terrain such as grass, the parent-child baby carriage body 1 can better adapt, providing more choices for parents to take their children out.
