[0030] Please see Figures 1-8 This utility model provides a technical solution:
[0031] A multi-dimensional airbag interlock control car child seat shock absorption device includes a car child seat assembly 1. An airbag protection assembly 2 is fixedly connected to one side of the car child seat assembly 1. An inertial passive assembly 3 and an air storage and delivery assembly 4 are fixedly connected to the inside of the car child seat assembly 1. The airbag protection assembly 2 includes an airbag body 21. A circulating air port 22 is opened on the inside of the airbag body 21. A filter block 23 is fixedly connected to the inside of the circulating air port 22. The inertial passive assembly 3 includes a guide rod 31. The outer side of the guide rod 31 slides on the inside of a guide hole 34. The guide hole 34 is opened on the inside of a counterweight block 33. The air storage and delivery assembly 4 includes an air cylinder 41. A second spring 42 is fixedly connected to the inside of the air cylinder 41. A push rod 43 is fixedly connected to one end of the second spring 42. A first silicone duckbill valve 44 and a second silicone duckbill valve 45 are fixedly connected to the inside of the air cylinder 41. A sealing ring 46 is fixedly connected to the outer side of the push rod 43. A pad 47 is fixedly connected to the end of the push rod 43 away from the second spring 42.
[0032] As a further implementation of this solution, the car child seat assembly 1 includes a seat body 11. The seat body 11 has a mounting groove 12, an air duct 13, and an air outlet 14 on its inner side. A constant pressure air hole 15 is provided at the lower end of the seat body 11 near the mounting groove 12. The constant pressure air hole 15 penetrates the inner side of the seat body 11 and is connected to the mounting groove 12. The air duct 13 is connected to the air outlet 14. The air outlet 14 is connected to the inner side of the airbag body 21. The mounting groove 12 is connected to the inner side of the air reservoir 41 near the first silicone duckbill valve 44. Through the above configuration, this structural design allows the gas inside the car child seat assembly 1 to be connected to the mounting groove 12 through the constant pressure air hole 15, ensuring smooth gas flow inside the device. This allows for rapid inflation during emergency braking, providing timely protection for the child's head and improving the device's response speed and safety.
[0033] As a further implementation of this solution, one side of the gas storage cylinder 41 is fixedly connected to the inner side of the mounting groove 12, and both the front and rear ends of the guide rod 31 are fixed to the inner side of the mounting groove 12. Through the above settings, the structural stability of the device during use is ensured, and the reliability and safety of the device are improved.
[0034] As a further implementation of this solution, the rear end of the airbag body 21 is a through structure, and the circulating air port 22 penetrates the inner side of the airbag body 21. The inner side of the airbag body 21 is connected to the circulating air port 22, and the rear end of the airbag body 21 is fixedly connected to the seat body 11. Through the above settings, gas can be quickly discharged and filled. At the same time, the aperture of the circulating air port 22 limits the gas loss speed and plays a role in gas damping. This design not only improves the buffering effect of the device, but also provides continuous shock absorption protection when the child's head is hit.
[0035] As a further implementation of this solution, a gap is provided between the outer side of the counterweight 33 and the inner side of the mounting groove 12. The first spring 32 is fixed at both the front and rear ends of the counterweight 33. The counterweight 33 is in contact with the pad 47. With the above settings, this design can respond quickly during emergency braking, prevent the child's head from colliding with the seat, and improve the protective performance of the device.
[0036] As a further implementation of this solution, the gas storage cylinder 41 has mounting holes on the inner side near the first silicone duckbill valve 44 and the second silicone duckbill valve 45. The push rod 43 is slidably connected to the inner side of the gas storage cylinder 41, and the outer side of the sealing ring 46 is in contact with the inner side of the gas storage cylinder 41. Through the above arrangement, the gas storage and delivery component 4 plays the role of passive gas delivery and continuous gas storage.
[0037] Workflow: During the use of the car child seat assembly 1, when the car brakes or accelerates to prevent the child's head from colliding with the seat body 11, the counterweight 33 moves forward due to inertia during braking. The counterweight 33 slides on the outside of the guide rod 31 through the guide hole 34. When the counterweight 33 moves forward, it presses against the pad 47. The pad 47 drives the push rod 43 to move into the air tank 41. At this time, the push rod 43 presses against the second spring 42. The second spring 42 buffers and resets the push rod 43 during its movement. The sealing ring 46 prevents gas from flowing between the push rod 43 and the air reservoir 41. Under the pushing action of the push rod 43, the gas inside the air reservoir 41 is filled through the first silicone duckbill valve 44 into the air guide channel 13 and the air outlet channel 14, and then enters the airbag body 21 through the air outlet channel 14. At this time, the airbag body 21 expands due to the rapid gas filling. The opening of the circulating air port 22 allows the gas inside the airbag body 21 to be discharged. The filter block 23 filters impurities in the gas. Because the aperture of the circulating air vent 22 is small, it can limit the rate at which gas escapes from the airbag body 21, thus acting as a gas damper. This provides shock absorption when the child's head impacts the airbag body 21. As the child's body bounces backward due to inertia, it ensures that there is still gas inside the airbag body 21 as a buffer. After braking, the elastic force of the second spring 42 pushes the counterweight 33 backward, and the counterweight 33 contacts the rear end pad 47. At this time, following the same principle, the airbag body 21 is inflated again, and the child's head bounces backward. When the child moves backward, their head will come into contact with the airbag body 21. The cushioning and softness of the airbag body 21 will protect the child's head. When the car is moving smoothly, the first spring 32 at the front and rear ends will reset the counterweight 33. External gas will enter the air tank 41 through the second silicone duckbill valve 45 to prepare for the next protection. Based on the above principles, the device can prevent the child's body from being thrown backward due to inertia and directly colliding with the seat when the car brakes, thus improving the child's safety. This protective measure is continuous.
[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
