[0043] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings.

[0044] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, this embodiment provides a backrest flipping and seat cushion lifting structure to form a bed, including a seat back 100, a seat base frame 200, a seat cushion 300, a backrest rotation drive 400, and a seat cushion rotation drive 500; the seat back 100 is pivotally connected to the seat base frame 200, and the backrest rotation drive 400 is installed at the pivot point between the seat back 100 and the seat base frame 200 to control the rotation of the seat back 100; one end of the seat cushion 300 is pivotally connected to the rear end of the seat base frame 200 through a connecting rod assembly 600, and the other end is pivotally connected to the front end of the seat base frame 200 through a connecting rod 310; the seat cushion rotation drive 500 is fixedly mounted on the seat base frame 200, and the seat cushion rotation drive 500 is kinetically connected to the connecting rod 310.

[0045] Specifically, when the user adjusts the seat, both the backrest rotation drive 400 and the seat cushion rotation drive 500 are activated. The backrest rotation drive 400 drives the seat back 100 to rotate relative to the seat base frame 200, thereby flattening the seat back 100. The seat cushion rotation drive 500 drives the connecting rod 310 to rotate, thereby swinging the front end of the seat cushion 300 forward and upward, thus lifting the front end of the seat cushion 300 forward and upward. At the same time, the rear end of the seat cushion 300 is lifted upward under the action of the connecting rod assembly 600, so that the seat cushion 300 is level with the seat back 100, thus making the car seat level as a bed.

[0046] The backrest rotation drive 400 uses an electric angle adjuster. The seat back 100 reclines flat via the backrest rotation drive 400, and the seat cushion is raised via the linkage 620 structure, enabling the car seat to achieve a bed mode.

[0047] See Figures 1-6 As shown, in an optional embodiment, the linkage assembly 600 includes a rocker arm 610 and a connecting rod 620. One end of the rocker arm 610 is pivotally connected to the seat base frame 200, and the other end is pivotally connected to the connecting rod 620. The end of the connecting rod 620 away from the rocker arm 610 is fixedly connected to the seat cushion 300.

[0048] The connecting rod 620 is fixedly connected to the rear end of the seat cushion 300, and the connecting rod 620 can be welded to the seat cushion 300.

[0049] The connecting rod 310 is obtuse-angled; a transition rod 320 is fixedly installed in the middle of the connecting rod 310, and the transition rod 320 is pivotally connected to the seat cushion rotation drive 500.

[0050] Specifically, the rear end of the seat cushion 300 is connected to the rear end of the seat base frame 200 via a rocker arm 610 and a connecting rod 620, and the front end of the seat cushion 300 is connected to the front end of the seat base frame 200 via a connecting rod 310. This forms a four-bar linkage structure with the seat cushion 300, rocker arm 610, connecting rod 310, and seat base frame 200. The seat cushion rotation drive 500 can adjust the swing angle of the connecting rod 310 via the adapter rod 320, thereby enabling the seat cushion rotation drive 500 to adjust the position of the seat cushion 300 through the four-bar linkage structure.

[0051] See Figures 1-6 As shown, in the optional solution of this embodiment, a shock-absorbing support block 330 is provided in the middle of the connecting rod 310, and a limiting support groove 210 adapted to the shock-absorbing support block 330 is provided on the seat bottom frame 200.

[0052] The limiting support groove 210 is equipped with a shock-absorbing pad.

[0053] Specifically, a shock-absorbing support block 330 is provided in the middle of the connecting rod 310, and a limiting support groove 210 is provided on the seat bottom frame 200. A shock-absorbing pad is provided in the limiting support groove 210. The shock-absorbing support block 330 in the middle of the connecting rod 310 can fall into the limiting support groove 210, so that the shock-absorbing support block 330 at the bottom of the connecting rod 310 can fall into the limiting support groove 210, and no abnormal noise will occur when the shock-absorbing support block 330 falls into the limiting support groove 210.

[0054] See Figures 1-6As shown, in an optional embodiment, the seat cushion rotation drive 500 includes a motor mounting base 510, a drive motor 520, and a drive screw 530; the motor mounting base 510 is fixedly mounted on the seat base frame 200, the drive motor 520 is rotatably mounted on the seat base frame 200, and the drive screw 530 is mounted on the drive motor 520; the drive screw 530 is pivotally connected to the connecting rod 310 via an adapter rod 320.

[0055] The motor mounting base 510 has a motor mounting hole 511, and the drive motor 520 is provided with a lead screw drive seat 521. The lead screw drive seat 521 is inserted into the motor mounting hole 511, and the drive lead screw 530 is inserted into the lead screw drive seat 521. The motor mounting base 510 has an arc-shaped groove 512, and the drive lead screw 530 is located in the arc-shaped groove 512, so that when the drive motor 520 drives the drive lead screw 530, the drive lead screw 530 can swing with the movement of the adapter rod 320.

[0056] Specifically, the motor mounting base 510 is fixedly installed on the seat base frame 200. When the drive motor 520 is working, it can drive the drive screw 530 to extend and retract relative to the screw drive seat 521, thereby causing the drive screw 530 to drive the adapter rod 320 to move. When the adapter rod 320 moves, the drive screw 530 can swing relative to the motor mounting base 510.

[0057] This embodiment provides a car seat, including a backrest that flips backward and a seat cushion that lifts up to form a bed structure.

[0058] Specifically, the car seat provided in this embodiment has the advantages of the above-mentioned backrest flipping backward and seat cushion lifting into a bed structure compared with the prior art, which will not be elaborated here.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
