Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0045] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings.

[0046] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, this embodiment provides a car seat that can be folded down into a bed, including a seat base frame 100, a seat basin 200, and a seat back 300; the front end of the seat basin 200 is pivotally connected to the front end of the seat base frame 100, and the rear end of the seat basin 200 is connected to the seat base frame 100 through a seat cushion drive assembly 400, which can drive the rear end of the seat basin 200 to lift; a backrest connecting seat 110 is fixedly provided at the rear end of the seat base frame 100, and the seat back 300 is pivotally connected to the backrest connecting seat 110 through an adjuster 310. The height of the pivot point between the seat back 300 and the backrest connecting seat 110 is the same as the height of the pivot point at the front end of the seat basin 200, so that the rear end of the seat basin 200 is raised and level with the rearward-tilted seat back 300.

[0047] Specifically, when the car seat is in use, it can be folded down into a bed. During the folding process, the seat back 300 is folded back, and the rear end of the seat basin 200 is raised through the seat cushion drive assembly 400. The height of the pivot point between the seat back 300 and the backrest connecting seat 110 is the same as the height of the pivot point at the front end of the seat basin 200, so that the seat basin 200 and the seat back 300 are in a completely flat state, realizing the function of folding down the seat into a bed.

[0048] The seat back connecting seat 110 is provided on the seat bottom frame 100. By setting the seat back connecting seat 110, the height of the seat back 300 is increased, so that when the seat back 300 is tilted backward, the seat back 300 will not interfere with the floor of the vehicle trunk, and the seat back 300 can be laid flat on the floor of the vehicle trunk.

[0049] See Figures 1-6 As shown, in an optional embodiment, the front end of the seat base frame 100 has a seat basin connecting seat 120 for pivotally connecting with the seat basin 200, a support pad seat 121 is provided on the seat basin connecting seat 120, and a support rod 210 that can abut against the support pad seat 121 is provided on the seat basin 200.

[0050] Among them, a buffer pad is provided on the support pad 121.

[0051] The rear end of the seat base frame 100 is provided with a support seat 130 for the rear end of the seat basin of the support seat 130, and a cushioning pad is provided on the support seat 130.

[0052] Specifically, a seat basin connecting seat 120 is provided on the seat base frame 100. When the seat basin 200 is not driven and lifted by the seat cushion driving assembly 400, the front end of the seat basin 200 can rest on the support cushion seat 121, and the rear end of the seat basin 200 can rest on the support seat 130, ensuring the stability of the seat basin 200.

[0053] In addition, cushioning pads are provided on both the support pad 121 and the bearing seat 130. The cushioning pads prevent abnormal noises between the seat basin 200 and the seat bottom frame 100.

[0054] See Figures 1-6 As shown, in an optional embodiment, the seat cushion drive assembly 400 includes a drive member 410 and a linkage assembly 420; the drive member 410 is disposed on the seat base frame 100, and the drive end of the drive member 410 can be pivotally connected to the bottom of the seat pan 200; one end of the linkage assembly 420 is pivotally connected to the bottom of the seat pan 200, and the other end is pivotally connected to the seat base frame 100.

[0055] The drive component 410 includes a drive motor 411, a pivot base 412, and a telescopic rod 413. The drive motor 411 is mounted on the pivot base 412, which is pivotally connected to the seat base frame 100. One end of the telescopic rod 413 is connected to the drive motor 411, and the other end is pivotally connected to the bottom of the seat basin 200.

[0056] The linkage assembly 420 includes a rocker arm 421 and a rocker arm 422; one end of the rocker arm 421 is pivotally connected to the seat base frame 100, and the other end is pivotally connected to the rocker arm 422; the end of the rocker arm 422 away from the rocker arm 421 is pivotally connected to the bottom of the seat basin 200.

[0057] Specifically, the operation of the drive motor 411 can drive the telescopic rod 413 to work. The extension or retraction of the telescopic rod 413 can drive the rear end of the seat basin 200 to swing up and down relative to its front end. When the rear end of the seat basin 200 swings up and down, the swing arm 421 and rocker arm 422 of the linkage assembly 420 will swing. Thus, when the drive motor 411 stops working and self-locks, the swing arm 421 and rocker arm 422 of the linkage assembly 420 can provide auxiliary support for the seat basin 200.

[0058] It should be noted that the drive motor 411 is mounted on the pivot base 412, which is pivotally connected to the seat base frame 100. Therefore, when the drive motor 411 drives the telescopic rod 413 to work, the telescopic rod 413 will swing as the seat pan 200 is raised. Thus, the telescopic rod 413 can drive the drive motor 411 and the pivot base 412 to rotate, thereby ensuring the normal raising of the seat pan 200.

[0059] In addition, the pivot base 412 is located at the front end of the seat bottom frame 100. With this arrangement, the bottom space requirements of the seat cushion drive assembly 400 on the middle and rear part of the seat pan 200 can be reduced. In the initial state when the seat pan 200 is not raised, the front end height of the seat pan 200 is higher than the middle and rear part height of the seat pan 200. By setting the seat cushion drive assembly 400 at the front end of the seat bottom frame 100, the bottom space at the front end of the seat pan 200 can be utilized, so that the basic height of the seat pan 200 itself does not need to be increased.

[0060] See Figures 1-6 As shown, in an optional embodiment, the car seat that can be folded down into a bed also includes an electric leg rest 500. The electric leg rest 500 includes a leg rest base 510, a telescopic lifting frame 520, a leg rest motor 530, and a leg rest support 540. The leg rest base 510 is fixedly mounted on the seat base frame 100, the telescopic lifting frame 520 is pivotally connected to the leg rest base 510, the leg rest motor 530 is pivotally connected to the leg rest base 510, and the output end of the leg rest motor 530 is pivotally connected to the telescopic lifting frame 520. The leg rest support 540 is fixedly mounted at the end of the telescopic lifting frame 520 away from the leg rest base 510.

[0061] Specifically, when the car seat is folded down into a bed, the electric leg rest 500 is activated, the leg rest motor 530 drives the telescopic lifting frame 520 to unfold and swing, and the telescopic lifting frame 520 drives the leg rest support 540 to swing upward and level with the seat cushion.

[0062] This embodiment provides a car, including a car seat that can be folded down into a bed.

[0063] Specifically, the automobile provided in this embodiment has the advantages of the aforementioned car seats that can be folded down into a bed compared with the prior art, which will not be repeated here.

[0064] 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.
