[0026] See also Figures 1 to 6 The utility model provides a technical solution: a double-screw lifting motor zero-gravity seat cushion skeleton structure, including a four-link assembly 1, a motor support front tube welding assembly 2, a half basin 3, an anti-diving pipe 4, a slide rail assembly 5, a screw lifting motor assembly 6 and a rear high-adjustment pipe assembly 7; the four-link assembly 1 includes a seat cushion side panel 8, a left high-adjustment connecting rod with a bushing 9, a left mounting plate 10 of the seat cushion side panel assembly, a right mounting plate 11 of the seat cushion side panel assembly and a right high-adjustment connecting rod with a bushing 12, the seat cushion side panel 8 and the high-adjustment connecting rod with a bushing The left 9 is connected by rivets, and the left mounting plate 10 of the seat cushion side panel assembly, the right mounting plate 11 of the seat cushion side panel assembly and the right high-adjustment connecting rod with bushing 12 are connected by rivets; the motor support front tube welding assembly 2 is connected to the four-link assembly 1, and the half basin 3 is fixed to the anti-diving pipe 4 with self-tapping screws, and the anti-diving pipe 4 is welded to the four-link assembly 1, and the front end of the screw lifting motor assembly 6 is connected to the motor support front tube welding assembly 2, and its rear end is connected to the slide rail assembly 5, and the rear high-adjustment pipe assembly 7 is connected to the slide rail assembly 5.

[0028] When the seat is adjusted to a zero-gravity posture, the left screw motor and the right screw motor in the screw lifting motor assembly 6 are started at the same time to drive the motor support front tube welding assembly 2 to rotate as a whole, and the motor support front tube welding assembly 2 is lifted as a whole, thereby driving the four-link assembly 1 to lift the seat to the zero-gravity posture position. Since there are two motors, the left screw motor and the right screw motor, and the two are relatively distributed, when the occupant sits on the seat, the occupant does not feel that the seat is sinking during the lifting process. The two motors provide stronger support for the seat cushion when the seat collides, and the seat cushion has stronger anti-diving ability and can also strengthen the strength of the seat cushion frame.

[0029] For further information, see Figure 3 The motor support front pipe welding assembly 2 includes a motor support front pipe 13, a high-profile motor mounting bracket on the left 14, a high-profile motor mounting bracket on the right 15, a welding nut on the left 16, a welding nut on the right 17 and two relatively distributed front lifting brackets 18.

[0032] In this embodiment, the left rail body 19 and the right rail body 20 can drive the seat cushion to move horizontally, the front upper rail bracket left 22 and the front upper rail bracket right 23 are respectively connected to a front lifting bracket 18, the rear upper rail bracket left 25 and the rear upper rail bracket right 26 are respectively connected to the screw high-adjustment rear connecting rod left 33 and the screw high-adjustment rear connecting rod right 34 in the rear high-adjustment tube assembly 7, and the lifting bracket left 27 and the lifting bracket right 28 are respectively connected to the screw motor left and the screw motor right in the screw lifting motor assembly 6 through the convex welding nut 29.

[0033] Furthermore, the screw lifting motor assembly 6 includes a left screw motor and a right screw motor, and the left screw motor and the right screw motor are used to drive the motor to support the lifting and lowering of the front tube welding assembly 2.

[0034] In this embodiment, when the seat is adjusted to a zero-gravity posture, the left screw motor and the right screw motor in the screw lifting motor assembly 6 are started simultaneously to drive the motor support front tube welding assembly 2 to rotate as a whole, and the motor support front tube welding assembly 2 is lifted as a whole, thereby driving the four-link assembly 1 to lift the seat to the zero-gravity posture position. Since there are two motors, the left screw motor and the right screw motor, and the two are relatively distributed, when the occupant sits on the seat, the occupant does not feel that the seat is sinking during the lifting process. The two motors provide stronger support for the seat cushion when the seat collides, and the seat cushion has stronger anti-diving ability and can also strengthen the strength of the seat cushion frame.

[0035] For further information, see Figure 5 The rear high-adjustment tube assembly 7 includes a rear high-adjustment tube 32, a left screw high-adjustment rear connecting rod 33 and a right screw high-adjustment rear connecting rod 34.

[0036] In this embodiment, the left screw high-adjustable rear link 33 and the right screw high-adjustable rear link 34 are respectively rotated to connect the left rear upper rail bracket 25 and the right rear upper rail bracket 26, so that the seat cushion can be raised and lowered as the motor supports the front tube welding assembly 2.

[0037] The working principle and usage process of the present invention are as follows: When the seat is adjusted to a zero-gravity posture, the left and right screw motors in the screw lifting motor assembly 6 are simultaneously activated to drive the motor support front tube welding assembly 2 to rotate as a whole, and the motor support front tube welding assembly 2 is lifted as a whole, thereby driving the four-link assembly 1 to lift the seat to the zero-gravity posture position. Because two motors, the left and right screw motors, are provided and relatively distributed, when the occupant sits on the seat, the occupant does not feel the seat sink during the lifting process. The two motors provide stronger support for the seat cushion in the event of a seat collision, enhance the seat cushion's anti-diving ability, and strengthen the seat cushion frame. Otherwise, the seat can be reset.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
