[0002] With the rapid advancement of science and technology, the automotive industry is experiencing a rapid proliferation of new technologies, driving increasing demands for both comfort and safety. Zero-gravity seats, known for their exceptional comfort, are experiencing rapid growth and widespread adoption, but there are still gaps in the field regarding their safety performance.

[0003] In zero-gravity mode, passengers are in a lying position and the adjustment range of the seat belts is limited. When the vehicle collides at high speed, the size and direction of the seat belt's restraint on the body are very different from those in a normal sitting position, making it very easy for problems such as diving to occur. As a result, the accident mortality rate and the severity of injuries in zero-gravity mode are much higher than those in a normal sitting position. Therefore, it is very urgent to improve the driving safety of zero-gravity seats in high-speed mode. Summary of the invention

[0019] Advantageous effects:

[0020] An energy-absorbing safety structure for the seat cushion skeleton of a zero-gravity seat is provided in an embodiment of the present invention, which includes a seat base, a seat basin, a lifting driving member, a lifting plate, and an energy-absorbing and collapsing plate; one end of the seat base is pivotally connected to the seat basin, one end of the lifting plate is pivotally connected to the seat base, and the other end is pivotally connected to the energy-absorbing and collapsing plate through a stepped bolt.

Through such a setting, the impact force of the human body on the seat basin is consumed, the pressing force between the human body and the seat basin is reduced, and the injury suffered by the human body is alleviated.

[0042] 、

[0043] this embodiment provides an energy-absorbing safety structure for the seat cushion frame of a zero-gravity seat, including a seat base 100, a seat basin 200, a lifting driving member 300, a lifting plate 400, and an energy-absorbing and collapsing plate 500; one end of the seat base 100 is pivotally connected to the seat basin 200, one end of the lifting plate 400 is pivotally connected to the seat base 100, and the other end is pivotally connected to the energy-absorbing and collapsing plate 500. The end of the energy-absorbing and collapsing plate 500 away from the energy-absorbing and collapsing plate 500 is pivotally connected to the seat basin 200. The seat base 100, the seat basin 200, the lifting plate 400, and the energy-absorbing and collapsing plate 500 form a multi-link structure; the lifting driving member 300 is disposed at the other end of the seat base 100, and the lifting driving member 300 is in transmission connection with the lifting plate 400.In an alternative solution of this embodiment, the lifting driving member 300 is a driving motor, and a driving gear 310 is provided at the output end of the driving motor. An arc-shaped toothed plate 410 is provided on the lifting plate 400.

[0044] Specifically, the rotation of the driving motor can drive the lifting plate to rotate clockwise or counterclockwise, so that the lifting plate 400 can drive the front end of the seat basin 200 to lift or lower.

[0045] In an alternative solution of this embodiment, a lower cross tube 110 is provided on the seat base 100. One end of the lifting plate 400 is pivotally connected to the lower cross tube 110, and a first connection hole for connecting with the energy-absorbing and collapsible plate 500 is provided at the other end.

[0046] Among them, an upper cross tube 210 is provided on the seat basin 200. One end of the energy-absorbing and collapsible plate 500 is pivotally connected to the upper cross tube 210, and the other end is connected to the lifting plate 400 through a step bolt 501.

[0047] In an alternative solution of this embodiment, a cross tube pivot hole 510, a second connection hole 520, and an energy-absorbing connection hole 530 are provided on the energy-absorbing and collapsible plate 500; the cross tube pivot hole 510 is used for pivotal connection with the upper cross tube 210, and the second connection hole 520 is used for connection with the lifting plate 400; a weakening wall 540 is provided between the energy-absorbing connection hole 530 and the second connection hole 520.

[0048] Among them, a plurality of collapsible energy-absorbing toothed plates 550 are provided in the energy-absorbing connection hole 530.

[0049] Among them, the plurality of collapsible energy-absorbing toothed plates 550 are symmetrically arranged in the energy-absorbing connection hole 530.

[0050] Among them, the energy-absorbing connection hole 530 is in a fishbone shape.

[0051] Specifically, the energy-absorbing and collapsible plate 500 is provided with a transverse pipe pivot hole 510, a second connection hole 520, and an energy-absorbing connection hole 530. A weakening wall 540 is provided between the energy-absorbing connection hole 530 and the second connection hole 520. When the car seat is operating in the zero-gravity mode normally, the step bolt 501 in the first connection hole of the second connection hole 520 of the energy-absorbing and collapsible plate 500 and the lifting plate 400 cannot break through the weakening wall 540, enabling the normal use of the car seat. When a frontal collision occurs in the car, the seat basin 200 is violently impacted by the user. The seat basin 200 will impact the energy-absorbing and collapsible plate 500. At this time, the step bolt 501 will impact and break the weakening wall 540 between the energy-absorbing connection hole 530 and the second connection hole 520. Then, the step bolt 501 will enter the energy-absorbing connection hole 530, and the step bolt 501 will impact a plurality of collapsible and energy-absorbing tooth plates 550 in the energy-absorbing connection hole 530, thereby causing the front end height of the seat basin 200 to decrease. During the descent, the impact energy of the human body on the seat basin 200 is absorbed, the pressure between the human body and the seat basin 200 is reduced, and the injury suffered by the human body is reduced.

[0052] Moreover, when the step bolt 501 impacts a plurality of collapsible and energy-absorbing tooth plates 550, the energy-absorbing and collapsible plate 500 will press the lifting plate 400 to rotate. The rotation of the lifting plate 400 will drive the lifting drive motor to rotate, thereby further reducing the height of the seat basin 200, further reducing the pressure between the human body and the seat basin 200, and reducing the injury suffered by the human body.

[0053] This embodiment provides a car seat, including an energy-absorbing and safety structure for the zero-gravity seat cushion skeleton.

[0054] Specifically, the car seat provided in this embodiment has the advantages of the above-mentioned energy-absorbing and safety structure of the zero-gravity seat cushion skeleton compared with the prior art, which will not be elaborated here.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
