Description
Technical Field
[0001] The utility model relates to the field of safety seats, and more specifically to a headrest side wing and a base support leg shock absorption and buffering of a PFU D30 child safety seat. Background Art
[0002] At present, a safety seat is a seat designed for children of different weights or ages, installed in a car, and can effectively improve the safety of children in a car. Many car accidents are caused by side collisions, and most child safety seats on the market do not have side collision protection devices. When a side collision occurs, they often cannot protect the children sitting in the car well. Some manufacturers have also produced child safety seats with side protection. The protection structure of the safety seat includes a foam board, an anti-side collision frame and an anti-side collision foam board, but the anti-side collision frame is in a straight plate shape, and the anti-side collision foam board is fixed on the anti-side collision frame. In an actual collision, the material of the anti-side collision foam board itself cannot completely buffer the impact of the side collision, and it will still cause damage to the child in the safety seat. In addition, due to the straight plate shape of the anti-side collision frame, the collision impact force is directly transmitted, and the child may collide back and forth between the two side frames. In the event of an accident, the force after the break will impact the baby's body or head, which is likely to cause secondary damage.
[0003] The present application achieves the effect of eliminating the buffering force on the legs and head of children during bumps through the shock-absorbing cooperation between the support plates. Utility Model Content

[0023] Please see attached Figure 1 , which is a shock-absorbing and buffering device for the headrest side wings and base support legs of a PFU D30 child safety seat disclosed by the utility model.
[0024] The utility model comprises a shell and two headrest rods, wherein the two headrest rods are inserted into the shell side by side, a connecting part is arranged in the shell, and the connecting part extends out of the shell along the bottom of the shell, and the connecting part is movably connected with a buffer mechanism.
[0025] In order to further optimize the above technical solution, in the headrest side wing and base support leg shock absorption and buffering of the above-mentioned PFU D30 child safety seat, the shock absorption device includes:
[0026] A fixing rod, wherein three fixing rods are provided, one end of the three fixing rods are fixedly connected together, and a movable slide rail is respectively provided in the three fixing rods;
[0027] A first connecting rod, wherein holes are respectively arranged at both ends of the first connecting rod, and movable components are respectively slidably connected to the two holes, and the first connecting rod is placed in the movable slide rail.
[0028] In order to further optimize the above technical solution, in the headrest side wing and base support leg shock absorption and buffering of the above PFU D30 child safety seat, the movable component includes:
[0029] a second connecting rod, the second connecting rod being movably connected to one end of the first connecting rod;
[0030] a third connecting rod, the third connecting rod being movably connected to the other end of the first connecting rod, and the first connecting rod and the second connecting rod being connected together via a fourth connecting rod;
[0031] The second connecting rod and the third connecting rod are placed in parallel.
[0032] In order to further optimize the above technical solution, in the headrest side wings and base support leg shock absorption and buffering of the above-mentioned PFU D30 child safety seat, the third connecting rod is elastically connected to the common end of the three fixing rods through an elastic part.
[0033] In order to further optimize the above technical solution, in the shock-absorbing and buffering of the headrest side wings and base support legs of the above-mentioned PFU D30 child safety seat, limit columns are respectively provided at both ends of the first connecting rod and at the second connecting rod and the third connecting rod. The limit columns are arranged in the slide rail and are slidably connected with the slot in the middle of the first connecting rod.
[0034] In order to further optimize the above technical solution, in the headrest side wings and base support leg shock absorption and buffering of the above-mentioned PFU D30 child safety seat, the fourth connecting rod and the fixed rod are connected through a movable component.
[0035] In order to further optimize the above technical solution, in the headrest side wings and base support leg shock absorption and buffering of the above-mentioned PFU D30 child safety seat, the three fixed connecting ends of the fixing rods are at an angle of 60° to each other.

After the impact, the material returns to its original soft state;
[0038] PFU D30 has the same functions as most commonly used protective materials, and when the material thickness is the same, it has a stronger ability to absorb energy and play a better protective role.

[0039] The energy-absorbing support legs at the bottom of the base effectively absorb the impact energy generated during a collision, providing cushioning and safety protection for the baby, and timely providing vertical cushioning protection. When the car collides and leans forward, the pur shock-absorbing pads in the support legs act as damping and shock-absorbing.
[0040] The present application eliminates the impact force received by the legs by sliding the first connecting rod in conjunction with the second connecting rod and the third connecting rod up and down, and passing a spring assembly between the fixing part. The first connecting rod, the second connecting rod and the fixing rod are respectively provided with three groups, which are respectively installed at the three ends of the fixing part. Through the cooperation of the three groups, the impact forces received in different directions are eliminated, thereby effectively preventing the impact force.
