[0037] The preferred embodiments of the present utility model are given below in conjunction with the accompanying drawings and described in detail.

[0038] like Figure 1As shown, an embodiment of the utility model provides a car seat frame, including a base 100, a backrest frame 200, a cushion frame 300, a first driving mechanism 400 and a second driving mechanism 500, the cushion frame 300 includes a first connecting rod assembly 310, a second connecting rod assembly 320 and a seat basin 330, the backrest frame 200 is rotatably connected to the base 100, and can rotate between a first position and a second position relative to the base 100, one end of the first connecting rod assembly 310 is hinged to the base 100, the other end of the first connecting rod assembly 310 is hinged to one end (front end) of the second connecting rod assembly 320, the other end (rear end) of the second connecting rod assembly 320 is slidably connected to the base 100, and one end of the seat basin 330 is hinged to the second connecting rod assembly 320. Hinged, one end of the first driving mechanism 400 is connected to the first connecting rod assembly 310, and the other end of the first driving mechanism 400 is connected to the base 100; one end of the second driving mechanism 500 is connected to the second connecting rod assembly 320, and the other end of the second driving mechanism 500 is connected to the seat basin 330. The first driving mechanism 400 can drive the first connecting rod assembly 310 to rotate relative to the base 100, and the rotation of the first connecting rod assembly 310 causes the second connecting rod assembly 320 to slide relative to the base 100, thereby changing the first connecting rod assembly 310 and the second connecting rod assembly 320 between the first form and the second form. The second driving mechanism 500 is used to drive the seat basin 330 to rotate relative to the second connecting rod assembly 320 between a stowed position and a raised position.

[0039] By the movement of the backrest frame 200, the first connecting rod assembly 310, the second connecting rod assembly 320 and the seat pan 330, the automobile seat frame can be in different states. When the automobile seat frame is in the first state, such as Figure 2A As shown, the backrest frame 200 is located in the design position, wherein the design position is between the first position and the second position, the first connecting rod assembly 310 and the second connecting rod assembly 320 are in the first state, and the seat pan 330 is in the stowed position. At this time, the angle between the backrest frame 200 and the plane where the base 100 is located (i.e., the XY plane) is a first preset angle (e.g., 110 degrees), and the car seat frame can be used for passengers to sit normally. When the car seat frame is in the second state, as shown in FIG. Figure 2B As shown, the backrest frame 200 rotates from the design position to the direction close to the cushion frame 300 by a second preset angle (e.g., 115 degrees), the first connecting rod assembly 310 rotates from the position of the first form to the direction away from the backrest frame 200, and brings the second connecting rod assembly 320 to slide relative to the base 100 in the direction away from the backrest frame 200, so that the first connecting rod assembly 310 and the second connecting rod assembly 320 are transformed from the first form to the second form. At this time, the automobile seat frame is folded to reduce its occupied space. When the automobile seat frame is in the third state, as shown in FIG. Figure 2CAs shown, the backrest frame 200 rotates from the design position to a third preset angle (e.g., 60-70 degrees) away from the seat cushion frame 300, the first connecting rod assembly 310 and the second connecting rod assembly 320 are in the first state, and the seat pan 330 is in the stowed position. At this time, the occupant can lie on the car seat. When the car seat frame is in the fourth state, Figure 2D As shown, the backrest frame 200 is located in the design position, the first link assembly 310 and the second link assembly 320 are in the first form, and the seat pan 330 is rotated relative to the second link assembly 320 by a fourth preset angle (e.g., 4-10 degrees) to move from the stowed position to the raised position. At this time, the seat pan 330 is raised relative to the second link assembly 320 by a preset distance (e.g., 25-50 mm) along the Z direction.

[0040] In the present invention, the X direction is a direction parallel to the ground and pointing to the front of the car, the Y direction is a direction parallel to the ground and pointing to the left side of the driver, and the Z direction is a direction perpendicular to the ground and pointing upward.

The base 100 can be fixed on the sliders 620a and 620b, so that the base 100 can follow the sliders 620a and 620b to slide along the slide rails 610a and 610b.

[0043] The base 100 may include two first fixing seats 110a, 110b and two second fixing seats 120a, 120b, wherein the first fixing seats 110a and the second fixing seats 120a are fixed on the slider 620a and arranged at intervals, and the first fixing seats 110b and the second fixing seats 120b are fixed on the slider 620b and arranged at intervals. The two first fixing seats 110a, 110b form the front end of the base 100, and the two second fixing seats 120a, 120b form the rear end of the base 100. The two second fixing seats 120a, 120b may be connected together by a first connecting pipe 130 to increase the strength of the base 100.

[0044] like Figure 3BAs shown, in some embodiments, the first connecting rod assembly 310 includes two first connecting rods 311a, 311b and a second connecting tube 312, and both ends of the second connecting tube 312 are respectively fixedly connected to the two first connecting rods 311a, 311b (for example, welded), the first connecting rod 311a is hinged to the first fixed seat 110a, and the first connecting rod 311b is hinged to the first fixed seat 110b; the two first connecting rods 311a, 311b are also hinged to one end of the second connecting rod assembly 320, and the other end of the second connecting rod assembly is respectively slidably connected to the second fixed seats 120a, 120b. Specifically, the bottom end of the first link 311a can be hinged to the first fixed seat 110a, the top end of the first link 311a can be hinged to the second link assembly 320, the bottom end of the first link 311b can be hinged to the first fixed seat 110b, the top end of the first link 311b can be hinged to the second link assembly 320, one end of the second connecting tube 312 is fixed between the bottom end and the top end of the first link 311a, and the other end is set between the bottom end and the top end of the first link 311b.

[0045] In some embodiments, the first driving mechanism 400 includes two motor push rod assemblies 400a and 400b, the motor push rod assembly 400a is located on a side close to the first fixed seat 110a and the second fixed seat 120a, and the motor push rod assembly 400b is located on a side close to the first fixed seat 110b and the second fixed seat 120b; the motor push rod assembly 400a includes a first motor 410a and a push rod 420a, and the motor push rod assembly 400b includes a first motor 410b and a push rod 420b, the first motors 410a and 410b are both fixed on the second connecting pipe 312, one end of the push rod 420a is connected to the first motor 410a, and the other end of the push rod 420a is connected to the second fixed The seat 120a is hinged, one end of the push rod 420b is connected to the first motor 410b, and the other end of the push rod 420b is hinged to the second fixed seat 120b. The first motor can drive the push rod connected to it to extend and retract, and the extension and retraction of the push rod can cause the first connecting rod to rotate relative to the first fixed seat; since the first connecting rod is hinged to one end of the second connecting rod assembly 320, and the other end of the second connecting rod assembly 320 is slidingly connected to the second fixed seats 120a and 120b, the second connecting rod assembly 320 will also rotate relative to the first connecting rod under the drive of the first connecting rod, and slide relative to the second fixed seat, thereby causing the first connecting rod assembly 310 and the second connecting rod assembly 320 to change between the first form and the second form.

[0046] In some embodiments, two first motor brackets 430a and 430b are fixed to the second connecting pipe 312, the first motor 410a is fixed to the first motor bracket 430a, and the motor 410b is fixed to the first motor bracket 430b.

[0048] In some embodiments, the second driving mechanism 500 may include a lifting tube 510, a second motor 520 and a screw rod 530. The second motor 520 is fixed on the fourth connecting tube 323. The second motor 520 is connected to the screw rod 530 through a nut to form a ball screw structure, so that the second motor 520 drives the screw rod 530 to slide relative to the second motor 520. One end of the screw rod 530 is connected to the lifting tube 510. Both ends of the lifting tube 510 are respectively hinged to the fourth connecting tube 323. The seat basin 330 is fixedly connected to the lifting tube 510. In this way, when the second motor 520 rotates, the screw rod 530 will move back and forth and push the lifting tube 510 to rotate relative to the fourth connecting tube 323, so that the seat basin 330 follows the lifting tube 510 to rotate relative to the second connecting rods 321a and 321b between the stowed position and the lifted position.

The shape of the bushing 720a can be configured so that the length extending in the direction of the slide groove 121a is greater than the length extending in the direction perpendicular to the slide groove 121a, such as an elliptical shape, to prevent the bushing 720a from deflecting during the sliding process; the bushing 720a is sleeved on the step shaft 711a of the step bolt 710a and is slidably configured in the slide groove 121a, the gasket 730a is also sleeved on the step shaft 711a of the step bolt 710a and cooperates with the bolt head 712a of the step bolt 710a to axially limit the bushing 720a, the nut is screwed on the step bolt 710a and cooperates with the second fixed seat 120a to axially limit the gasket 730a, and the end face of the gasket 730a slides and rubs with the second fixed seat 120a.

[0059] Similarly, a slide groove 121b is provided on the second fixed seat 120b, and the third connecting piece 326b is fixed to another sliding member, which is slidably set in the slide groove 121b, so that the second fixed seat 120b is slidingly connected to the second fixed seat 120b; the connection relationship between the third connecting piece 326b, the sliding member and the slide groove 121b is the same as that between the second fixed seat 120a, the sliding member 700a and the slide groove 121a, and will not be repeated here.

[0060] like Figure 5A , Figure 5B and Figure 5CAs shown, the hinge point A between the first connecting rod 311a and the second connecting rod 321a is located in front of the fixed point B between the fourth connecting tube 323 and the second connecting rod 321a, the lifting tube 510 is located between the two first connecting rods 311a and 311b, and there is a gap between the two ends of the lifting tube 510 and the two first connecting rods 311a and 311b, and there is also a gap between the hinge point between the first connecting piece 325a and the second connecting piece 511a and the two first connecting rods 311a and 311b, so the lifting tube 510 and the first connecting rod can rotate independently without interfering with each other; the fourth connecting tube 323 can be a bent tube, which is bent toward the lifting tube 510, so that the second motor 520 is located in front of the fixed point B.
