The synchronizing rod is located near the center of the seat cushion bottom frame and is rotatable relative to the bottom frame. A rear lifting motor is also mounted on the bottom frame to drive the synchronizing rod. Lifting angle adjusters are located near both ends of the synchronizing rod, and both ends of the lifting angle adjusters are welded to the seat cushion rear lifting support arm and the seat cushion bottom frame, respectively. The seat cushion rear lifting support arm is welded to the seat cushion rear cross tube. Both ends of the seat cushion rear cross tube are rotatably connected to the left and right seat cushion side panel frames. The front ends of the left and right seat cushion side panel frames are rotatably connected to the upper end of the seat cushion front connecting rod, and the lower end of the seat cushion front connecting rod is rotatably connected to the front end of the seat cushion bottom frame.

[0006] As a preferred embodiment of this invention, the backrest frame is installed between the two seat cushion side plate frames.

[0007] This utility model also provides a seat, which is a three-row zero-gravity seat, including three rows of zero-gravity seats with sliding rails and three rows of fixed zero-gravity seats, and the three rows of zero-gravity seats are equipped with the above-mentioned seat cushion lifting mechanism.

[0008] As a preferred embodiment of this utility model, the three rows of zero-gravity seats with sliding rails are provided with long sliding rails for adjusting the seat forward and backward.

[0009] Advantages and beneficial effects of this utility model: The seat cushion lifting mechanism of this utility model can achieve the overall lifting of the backrest and seat cushion by improving the overall structure, and can increase the lifting angle of the seat cushion, increasing H30 (the vertical distance from point H to the vehicle floor), which can better adapt to personalized needs and improve visibility, seating comfort and ease of getting on and off the vehicle.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; or they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0016] like Figures 1 to 3As shown, this embodiment provides a seat cushion rear lifting mechanism for a three-row zero-gravity seat with sliding rails, including a seat cushion side panel frame 2, a seat cushion rear cross tube 3, a seat cushion rear lifting support arm 4, a rear lifting motor 5, a synchronizing rod 6, a lifting angle adjuster 7, a seat cushion front connecting rod 8, a backrest frame 9, and a seat cushion bottom frame 10; wherein, the synchronizing rod 6 is provided on the seat cushion bottom frame 10 near the middle position, and the synchronizing rod 6 is rotatable relative to the seat cushion bottom frame 10; the rear lifting motor 5 is also installed on the seat cushion bottom frame 10, and the rear lifting motor 5 is used to drive the synchronizing rod 6 to rotate. The synchronizing rod 6 is equipped with lifting angle adjusters 7 near both ends. The two ends of the lifting angle adjusters 7 are welded to the rear lifting support arm 4 and the bottom frame 10 of the seat cushion, respectively. The rear lifting support arm 4 is welded to the rear horizontal tube 3 of the seat cushion. The two ends of the rear horizontal tube 3 of the seat cushion are rotatably connected to the left and right side plate frames 2 of the seat cushion. The front ends of the left and right side plate frames 2 are rotatably connected to the upper ends of the front connecting rod 8 of the seat cushion. The lower ends of the front connecting rod 8 of the seat cushion are rotatably connected to the front ends of the bottom frame 10 of the seat cushion. The backrest frame 9 is installed between the two side plate frames 2 of the seat cushion.

[0017] This utility model also provides a seat, which is a three-row zero-gravity seat, including three rows of zero-gravity seats with sliding rails and three rows of fixed zero-gravity seats, and the three rows of zero-gravity seats are equipped with the above-mentioned seat cushion lifting mechanism.

[0018] In this utility model, the three rows of zero-gravity seats with sliding rails are equipped with a long sliding rail 1 for adjusting the seat front and rear. The three rows of seats can be adjusted to a comfortable position according to the needs of the passengers. The adjustment process is first achieved through the long sliding rail 1 for adjusting the seat front and rear, and then the rear lift adjustment is performed. The rear lift adjustment method of the seat cushion is as follows:

[0019] The seat cushion is powered by the rear lifting motor 5, which is fixed to the seat cushion bottom frame 10. After being powered on, the rear lifting motor 5 transmits power to the lifting angle adjuster 7 through the synchronizing rod 6. The two ends of the lifting angle adjuster 7 are welded to the rear lifting arm 4 and the seat cushion bottom frame 10, respectively. The seat cushion bottom frame 10 is a fixed part, so the rear lifting arm 4 will rotate. The rear lifting arm 4 is welded to the rear horizontal tube 3 of the seat cushion. At this time, the rear horizontal tube 3 of the seat cushion will drive the seat cushion side plate frame 2 to lift.

[0020] In this embodiment, the seat cushion side plate frame 2 and the seat cushion rear horizontal tube 3, the seat cushion rear lifting support arm 4 and the seat cushion front connecting rod 8 can all rotate relative to each other, and the seat cushion side plate frame 2 and the backrest frame 9 are fastened with bolts, so that the backrest and the seat cushion can be lifted as a whole.
