For example, by driving the base assembly 210 to rotate relative to the base 100 through the first drive mechanism 400, the overall height of the car seat frame can be adjusted, so that it can switch between the lowest height posture and the highest height posture; the second drive mechanism 400 can drive the seat basin assembly 220 to rotate and slide relative to the base assembly 210, so that the seat basin assembly 220 moves forward as a whole along the X direction, and at the same time the third motor 360 can drive the backrest frame 300 to rotate relative to the base assembly 210 so that it is close to the base assembly 210, thereby switching the car seat frame to a folded state. After folding, the base 100 can also be moved forward along the X direction by the third drive mechanism, thereby releasing space behind the seat; the third motor 360 can drive the backrest frame 300 to rotate relative to the base assembly 210, and the angle of the backrest frame 300 can also be adjusted to adapt to different occupants. When the backrest frame 300 rotates away from the base assembly 210 to be basically horizontal, the car seat frame is in a state as follows: Figure 13 As shown, the vehicle seat frame can be folded back into the bed position, and the passenger can lie on it.

[0062] It is understandable that, in addition to Figure 11-14 In addition to the postures shown, the automobile seat frame can also achieve any other suitable postures through the movement of various components.

[0063] As mentioned above, the first driving mechanism 400 can adjust the height of the car seat frame by extending and retracting. When the first driving mechanism 400 is extended (i.e., the length between the two ends becomes longer), the height of the car seat frame will become higher. When the first driving mechanism 400 is retracted (i.e., the length between the two ends becomes shorter), the height of the car seat frame will become lower. Figure 15 As shown, when the car seat frame is at its lowest height, the length between the two ends of the first drive mechanism 400 is the shortest; Figure 16 As shown, when the car seat frame is at its highest position, the length between the two ends of the first driving mechanism 400 is the longest.

[0064] like Figure 17 and Figure 18As shown, in some embodiments, the car seat frame may further include a lifting mechanism 700, which is fixed to the vehicle body frame, and the sliding mechanism 600 is provided on the lifting mechanism 700. The lifting mechanism 700 is used to make the sliding mechanism 600, the base 100, the base assembly 210, the seat basin assembly 220 and the backrest frame 300 rise or fall along the Z direction, thereby adjusting the height of the car seat frame. In other words, in this embodiment, Figure 1 A lifting mechanism 700 is added to the bottom of the automobile seat frame, so that the overall height of the automobile seat frame can be further adjusted through the lifting mechanism 700.

[0065] The lifting mechanism 700 may be any suitable lifting device, such as a cylinder lifting device, a cross arm lifting device, a ball screw lifting device, etc. The lifting mechanism 700 may be driven electrically, hydraulically, or in any other suitable manner.

[0066] An embodiment of the present invention also provides a car seat, which includes the car seat frame as described in the above embodiment.

[0067] The car seat and car seat frame of the embodiment of the utility model can be folded by the movement of the seat basin assembly 220 relative to the base assembly 210, and the height can be adjusted by the rotation of the base assembly 210 relative to the base 100, thereby meeting the riding needs of different passengers; the height can be further adjusted by the lifting mechanism 700, so that its control range is wider and its adaptability is also wider.
