[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0021] See Figure 1 and Figure 2 The car seat 1 includes a seat cushion bracket 10, a backrest bracket 20, a first drive assembly 30, and a second drive assembly 40.

[0022] The seat cushion bracket 10 is used to install the seat cushion 100. The seat cushion bracket 10 is a foldable and sinkable bracket. The backrest bracket 20 is used to install the backrest 200. The backrest bracket 20 is rotatably connected to the seat cushion bracket 10. The first drive assembly 30 is used to control the seat cushion bracket 10 to fold or unfold in the thickness direction, so as to drive the seat cushion 100 to sink or rise. The second drive assembly 40 is used to drive the backrest bracket to rotate toward the seat cushion bracket 10 when the first drive assembly 30 controls the seat cushion bracket 10 to fold in the thickness direction, and to drive the backrest bracket to rotate away from the seat cushion bracket 10 when the first drive assembly 30 controls the seat cushion bracket 10 to unfold in the thickness direction.

[0023] Specifically, the seat cushion bracket 10 is mounted on the car floor, the first drive assembly 30 is mounted on the seat cushion bracket 10, and the second drive assembly 40 is mounted on the backrest bracket 20. When the car seat 1 is in a normal sitting position, the backrest bracket 20 has a certain tilt angle relative to the seat cushion bracket 10. When the car seat 1 changes from a normal sitting position to a compressed bed position, the seat controller of the car seat 1 simultaneously activates the first drive assembly 30 and the second drive assembly 40. The first drive assembly 30 drives the seat cushion bracket 10 to fold along its thickness, and the second drive assembly 40 drives the backrest bracket 20 to rotate toward the seat cushion bracket 10. After the seat cushion bracket 10 and the backrest bracket 20 are folded, the volume of the car seat 1 is compressed. By simultaneously driving the backrest bracket 20 and the seat cushion bracket 10 with the first drive assembly 30 and the second drive assembly 40, the folding efficiency is improved.

[0024] The seat cushion bracket 10 of this application sinks or rises along the thickness direction. The first drive assembly 30 drives the seat cushion bracket 10 to fold, reducing the space occupied by the seat cushion bracket 10 and improving the utilization rate of the vehicle interior space. The second drive assembly 40 drives the backrest bracket 20 to rotate toward the seat cushion bracket 10. The first drive assembly 30 and the second drive assembly 40 drive the seat cushion bracket 10 and the backrest bracket 20 to move simultaneously, coordinating the movement process of the seat cushion bracket 10 and the backrest bracket 20, and improving the folding efficiency of the car seat 1.

[0025] See Figure 3 In one embodiment, the seat support 10 includes a first support frame 110, a second support frame 120, and a rotating member 130.

[0026] The first support frame 110 is used to mount the seat cushion 100. The second support frame 120 is opposite to and spaced apart from the first support frame 110. The two ends of the rotating member 130 are rotatably connected to the first support frame 110 and the second support frame 120, respectively. The first drive assembly 30 is used to drive the rotating member 130 to rotate relative to the second support frame 120, so as to adjust the distance between the first support frame 110 and the second support frame 120, thereby realizing the folding and unfolding of the seat cushion support 10.

[0027] Specifically, one end of the rotating component 130 is rotatably connected to the first support frame 110, and the other end of the rotating component 130 is rotatably connected to the second support frame 120. The first drive assembly 30 drives the rotating component 130 to rotate relative to the second support frame 120. At the same time, the rotating component 130 drives the first support frame 110 to rotate, thereby moving the first support frame 110 forward and downward to reduce the distance between the first support frame 110 and the second support frame 120, so that the seat cushion support 10 can be converted from a normal sitting posture to a compressed bed posture.

[0028] See Figure 1 and Figure 3In one embodiment, there are two rotating members 130, which are arranged opposite to each other and spaced apart. Both rotating members 130 are rotatably connected to the first support frame 110 and the second support frame 120. The first driving assembly 30 drives the two rotating members 130 to rotate simultaneously.

[0029] Specifically, two rotating parts 130 are spaced apart within the seat support 10. Each rotating part 130 is rotatably connected to the first support frame 110 and the second support frame 120. That is, the rotating part 130 can rotate relative to the first support frame 110 and the second support frame 120. The first drive assembly 30 drives the two rotating parts 130 to rotate simultaneously, thereby causing the first support frame 110 to sink or move up. By controlling the two rotating parts 130 simultaneously, the two rotating parts 130 can rotate at the same time, thereby improving the folding efficiency of the first support frame 110 and reducing the folding time.

[0030] In another embodiment, the number of rotating members 130 is four, six, or eight. For example, when the number of rotating members 130 is four, two rotating members 130 are arranged opposite to the other two rotating members 130 and spaced apart. When the number of rotating members 130 is six, three rotating members 130 are arranged opposite to the other three rotating members 130 and spaced apart. It should be noted that the number of rotating members 130 can be an even number.

[0031] See Figure 3 In one embodiment, the first drive assembly 30 includes a first motor 310 and two transmission parts 320. The first motor 310 includes a first output shaft 311 and a second output shaft 312 coaxially arranged. The two transmission parts 320 are respectively connected to the first output shaft 311 and the second output shaft 312. One transmission part 320 is movably connected to the second support frame 120 and a rotating member 130, and the other transmission part 320 is movably connected to the second support frame 120 and another rotating member 130. Under the drive of the first motor 310, the two transmission parts 320 drive the two rotating members 130 to rotate simultaneously relative to the second support frame 120.

[0032] Specifically, the first output shaft 311 and the second output shaft 312 of the first motor 310 are coaxial. The two transmission parts 320 are connected to the first output shaft 311 and the second output shaft 312 respectively. The first motor 310 drives the two transmission parts 320 simultaneously, enabling the two transmission parts 320 to move synchronously. The transmission parts 320 are connected to the second support frame 120. The first motor 310 drives the transmission parts 320 to rotate and move forward relative to the second support frame 120, thereby driving the rotating component 130 to rotate. By setting transmission parts 320 and rotating components 130 on both sides of the second support frame 120, not only is the support force on the first support frame 110 increased, but the folding efficiency is also improved. Compared with setting two motors each connected to the transmission parts 320, the number of motors and the error in motor start-up time are reduced, and the synchronization of controlling the transmission parts 320 is improved.

[0033] See Figure 3 In one embodiment, the second output shaft 312 is connected to a flexible shaft 330, which in turn is connected to a transmission unit 320. The flexible shaft 330 extends the length of the second output shaft 312. The flexible shaft 330 has good flexibility and can easily transmit power or motion along curved or winding paths. Connecting the second output shaft 312 and the transmission unit 320 through the flexible shaft 330 greatly simplifies the connection from the second output shaft 312 to the transmission unit 320.

[0034] See Figure 3 In one embodiment, both transmission parts 320 are connected to the support rod 80.

[0035] Specifically, the two transmission parts 320 are connected by a support rod 80, which is rotatably connected to the two rotating parts 130. The transmission parts 320 push the support rod 80, which in turn pushes the rotating parts 130 to rotate. The support rod 80 connects the two transmission parts 320 and the two rotating parts 130, further improving the synchronicity between the two rotating parts 130. This ensures that the rotation angles of the two rotating parts 130 remain uniform, and the forces on both ends of the first support frame 110 are even, reducing the probability of damage to the first support frame 110.

[0036] See Figure 3 and Figure 4 In one embodiment, the transmission unit 320 includes a turbine 321 and a worm 322. The worm 322 meshes with the turbine 321, the turbine 321 is connected to the first output shaft 311, and the worm 322 is movably connected to the second support frame 120.

[0037] Specifically, the first output shaft 311 rotates. Since the first output shaft 311 is connected to the turbine 321, the first output shaft 311 drives the turbine 321 to rotate. The turbine 321 meshes with the worm 322, and the turbine 321 drives the worm 322 to rotate. The axis of the turbine 321 is perpendicular to the axis of the worm 322, and the rotation direction of the turbine 321 is also perpendicular to the rotation direction of the worm 322. The worm 322 is movably connected to the first support frame 110. The first output shaft 311 of the first motor 310 indirectly drives the worm 322 to move relative to the first support frame 110 along the extension direction of the worm 322. The worm 322 pushes the rotating component 130 to rotate, thereby adjusting the gap between the first support frame 110 and the second support frame 120.

[0038] In one embodiment, the turbine 321 is connected to the second output shaft 312, and the worm gear 322 is movably connected to the second support frame 120. The second output shaft 312 drives the turbine 321 to rotate, and the turbine 321 meshes with the worm gear 322. The turbine 321 drives the worm gear 322 to rotate, and the worm gear 322 is movably connected to the first support frame 110. The second output shaft 312 of the first motor 310 indirectly drives the worm gear 322 to move relative to the first support frame 110 along the extension direction of the worm gear 322. The worm gear 322 pushes the rotating member 130 to rotate, thereby adjusting the gap between the first support frame 110 and the second support frame 120.

[0039] See Figure 3 In one embodiment, the car seat 1 further includes two support seats 50. The two support seats 50 are fixedly connected to the seat cushion bracket 10. The support seats 50 are sleeved on the outside of the worm gear 322. The support seats 50 are provided with internal threads and match the external threads of the worm gear 322.

[0040] Specifically, two support seats 50 are respectively sleeved on the worm gears 322 of the two transmission parts 320. The internal threads of the support seats 50 and the external threads of the worm gears 322 are matched with each other, so that the worm gears 322 can move forward or backward simultaneously during the rotation of the worm gears 322 relative to the support seats 50. The support seats 50 provide support for the worm gears 322, so that the worm gears 322 push the first support frame 110 to fold relative to the second support frame 120.

[0041] In one embodiment, the car seat 1 further includes a slide rail 70 and a third drive assembly 60. The seat cushion support 10 is slidably mounted on the slide rail 70, and the third drive assembly 60 is used to drive the seat cushion support 10 to slide on the slide rail 70.

[0042] Specifically, the seat cushion bracket 10 is mounted on the slide rail 70 and can slide along the length of the slide rail 70. The third drive assembly 60 is mounted on the seat cushion bracket 10 and can drive the seat cushion bracket 10 to slide on the slide rail 70. During the process of the car seat 1 changing from a normal state to a compressed bed state, the first drive assembly 30 drives the seat cushion bracket 10 to compress and fold, the third drive assembly 60 drives the seat cushion bracket 10 to slide forward, and the second drive assembly 40 drives the backrest bracket 20 to fold toward the seat cushion bracket 10, so as to compress the car seat 1 as a whole. Then the car seat 1 and the support plate are installed to form a bed.

[0043] Furthermore, the third drive assembly 60 includes a second motor that drives the seat cushion bracket 10 to slide on the slide rail 70. During the process of transforming into a compressed bed state, the second motor drives the second support frame 120 to slide forward, leaving space for the backrest seat and making it easier to reduce the overall height of the car seat 1.

[0044] See Figure 1 In one embodiment, the surface of the backrest support 20 away from the seat cushion support 10 is a plane.

[0045] Specifically, when the car seat 1 is compressed into a bed state, the support plate and the backrest bracket 20 together form a bed. The surface of the backrest bracket 20 away from the seat cushion bracket 10 is flat, that is, the first surface 21 of the backrest bracket 20 is flat, which makes it easy for the backrest bracket 20 and the support plate to be installed into a bed, and when the car seat 1 is in a normal state, it is easy to store the support plate on the surface of the backrest bracket 20.

[0046] In other embodiments, the surface of the backrest support 20 on the side away from the seat cushion support 10 may also be curved.

[0047] This application also protects a vehicle including the car seat 1 as described in any of the above claims. The vehicle includes gasoline-powered vehicles, electric vehicles, hybrid vehicles, and hydrogen fuel cell vehicles, and also includes sedans, SUVs, and commercial vehicles, etc. It should be noted that this application does not limit the type of vehicle. The specific structure of the car seat 1 has been described above and will not be repeated here.

[0048] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
