[0035] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0036] In related technologies, vehicle seats have a zero-gravity adjustment function, which allows users to recline completely to improve their comfort. However, the zero-gravity adjustment function is achieved by motor drive, rotation shaft, and other components such as an adjuster, resulting in a complex seat structure and high cost. Therefore, how to optimize the seat structure, improve user comfort, and reduce overall cost has become an urgent problem to be solved in this field.

[0037] The following is for reference. Figures 1-6 This invention describes a seat assembly for a vehicle according to an embodiment of the present invention.

[0038] The vehicle seat assembly 1 according to the present invention includes: a support assembly 11 and a seat assembly 12, the seat assembly 12 being disposed on the support assembly 11; and a first adjustment mechanism 131, the first adjustment mechanism 131 being disposed on the floor of the vehicle and connected to the support assembly 11, the first adjustment mechanism 131 being adapted to drive the support assembly 11 to rotate relative to the floor to adjust the tilt angle of the seat assembly 12.

[0039] Specifically, the seat assembly 1 includes a support assembly 11 and a seat assembly 12. The seat assembly 12 is disposed on the support assembly 11, which supports the bottom and rear of the seat assembly 12, thereby supporting the entire seat assembly 12. A first adjustment mechanism 131 is provided on the vehicle floor. The first adjustment mechanism 131 cooperates with the support assembly 11 and drives the support assembly 11 to rotate relative to the floor, thereby adjusting the tilt angle between the support assembly 11 and the seat assembly 12 relative to the floor. This allows for multi-directional adjustments according to the specific needs of the passenger. By adjusting the tilt angle of the seat assembly 12, the user's body weight is distributed more evenly on the seat, reducing pressure on specific areas and improving passenger comfort. The first adjustment mechanism 131 drives the support assembly 11, improving comfort. Furthermore, it eliminates the need for an angle adjuster and a separate rotating shaft between the seat cushion 121 and the backrest 122, reducing the overall cost of the seat assembly 1.

[0040] The seat assembly 1 according to this utility model includes a support assembly 11 and a seat assembly 12. The seat assembly 12 is disposed on the support assembly 11, and the support assembly 11 can provide overall support for the seat assembly 12. A first adjustment mechanism 131 is provided between the floor and the seat assembly 12. The first adjustment mechanism 131 cooperates with the support assembly 11 to drive the support assembly 11 to rotate relative to the floor, thereby adjusting the overall tilt angle of the seat assembly 12. By adjusting the tilt angle of the seat assembly 12, the user's body weight is more evenly distributed on the seat, reducing pressure on specific areas and improving passenger comfort. By driving the support assembly 11 through the first adjustment mechanism 131, there is no need to set an angle adjuster and a separate rotating shaft between the seat cushion 121 and the backrest 122, thus reducing the overall cost of the seat assembly 1.

[0041] According to some embodiments of the present invention, the first adjustment mechanism 131 includes: a base 10, which is disposed on the floor, and a first base support 101 and a second base support 102 are formed on the base 10; a first rod 141 and a second rod 142, one end of the first rod 141 is hinged to the first base support 101, one end of the second rod 142 is hinged to the second base support 102, and the other ends of the first rod 141 and the second rod 142 are respectively hinged to the support assembly 11. The pivot axis of one end of the first rod 141 and the pivot axis of one end of the second rod 142 are arranged parallel to each other. The first rod 141 and the second rod 142 can swing synchronously in the front-rear direction of the vehicle and drive the support assembly 11 to move. The length of the first rod 141 is greater than or less than the length of the second rod 142.

[0042] like Figures 1-5As shown, the first adjustment mechanism 131 includes a base 10, a first rod 141, and a second rod 142. A first base support 101 and a second base support 102 are formed on the base 10. One end of the first rod 141 is hinged to the first base support 101, and one end of the second rod 142 is hinged to the second base support 102. The other end of the first rod 141 is hinged to the support assembly 11, and the other end of the second rod 142 is also hinged to the support assembly 11. The first rod 141 and the second rod 142 are spaced apart between the base 10 and the support assembly 11, and one end of the first rod 141 is hinged to the first base support 101. The hinge rotation axis is set parallel to one end of the second rod 142 and the hinge rotation axis of the second base bracket 102, defining a four-bar linkage between the first rod 141, the base 10, the second rod 142 and the support assembly 11. By driving the first rod 141 and the second rod 142 to move, the support assembly 11 can be driven to move synchronously. By setting the pivot axis of the first rod 141 and the second rod 142 at the hinged end of the base 10 parallel, it can be ensured that the first rod 141 and the second rod 142 remain synchronous when swinging, so that the support assembly 11 can move smoothly without twisting or jamming. The length of the first rod 141 is configured to be greater than or less than the length of the second rod 142. For example, the first rod 141 is located at the front end of the support assembly 11, and the second rod 142 is located at the rear end of the support assembly 11. If the length of the first rod 141 is the same as the length of the second rod 142, it is impossible to adjust the tilt angle of the seat assembly 12 relative to the floor during the swinging of the first rod 141 and the second rod 142. By configuring the length of the first rod 141 to be greater than or less than the length of the second rod 142, the support assembly 11 can be driven to raise the front of the seat assembly 12 and lower the rear of the seat assembly 12 by driving the first rod 141 and the second rod 142 to swing, thereby raising the tilt angle between the seat assembly 12 and the floor. This design can optimize the adjustment performance of the seat according to specific usage needs, so that the first adjustment mechanism 131 can provide more flexible and precise seat tilt angle adjustment, bringing a better riding experience to passengers.

[0043] According to some embodiments of the present invention, the support assembly 11 has a first mating bracket 143 and a second mating bracket 144 extending toward the floor. The first mating bracket 143 is adapted to be hinged to the other end of the first rod 141, and the second mating bracket 144 is adapted to be hinged to the other end of the second rod 142. The first adjustment mechanism 131 further includes a first drive motor 151, which is disposed on the first base bracket 101 and / or the second base bracket 102 and is adapted to drive the first rod 141 and / or the second rod 142 to swing relative to the floor to move the support assembly 11.

[0044] like Figures 1 to 5As shown, a first mating bracket 143 and a second mating bracket 144 are formed on the support assembly 11. The first mating bracket 143 and the second mating bracket 144 extend toward the base 10, so that the first mating bracket 143 and the first rod 141 are hinged, and the second mating bracket 144 and the second rod 142 are hinged. This ensures that the movement of the first rod 141 and the second rod 142 can be directly transmitted to the support assembly 11, thereby driving the seat to make corresponding tilt adjustments. The first drive motor 151 is responsible for driving the first rod 141 and the second rod 142 to swing relative to the base 10. The first drive motor 151 can also drive the first rod 141 and the second rod 142 to move simultaneously, ensuring that the movement of the first rod 141 and the second rod 142 is synchronized, making the movement of the support assembly 11 and the seat assembly 12 more stable. A control panel for controlling the opening and closing of the first drive motor 151 can be provided on the seat assembly 12. Through the control panel inside the vehicle, the first drive motor 151 can be turned on and the tilt angle of the seat can be selected and adjusted until the seat is adjusted to an angle that meets the user's comfort. Since the other ends of the first rod 141 and the second rod 142 are hinged to the first mating bracket 143 and the second mating bracket 144 on the support assembly 11, respectively, the swinging of the first rod 141 and the second rod 142 will directly drive the support assembly 11 and the seat assembly 12 on it to make corresponding tilt adjustments. By controlling the rotation direction and angle of the first drive motor 151, different tilt angles of the seat can be achieved, thereby meeting the personalized needs of users. By driving the first rod 141 and the second rod 142 through the first drive motor 151, very precise angle adjustment can be achieved, and the tilt angle adjustment of the seat does not require manual adjustment. It can be completed by simply pressing a button or touching the touch screen, which improves the convenience of use.

[0045] According to some embodiments of the present invention, the seat assembly 12 has a first extreme position tilted toward the front of the vehicle and a second extreme position tilted toward the rear of the vehicle. In the first extreme position, the angle between the first rod 141 and the base 10 is α1, and in the second extreme position, the angle between the second rod 142 and the base 10 is α2, and satisfies: 0°<α1≤90°, 0°<α2≤90°.

[0046] Specifically, the seat assembly 12 has a first extreme position tilting towards the front of the vehicle. In this first extreme position, the first rod 141 tilts towards the front of the vehicle, and the angle between the first rod 141 and the base 10 is α1, satisfying: 0° < α1 ≤ 90°. The seat assembly 12 also has a second extreme position tilting towards the rear of the vehicle. In this second extreme position, the second rod 142 tilts towards the rear of the vehicle, and the angle between the second rod 142 and the base 10 is α2, satisfying: 0° < α2 ≤ 90°. Figure 6As shown in the figure, the dashed lines represent the structural schematic diagrams of the first rod 141 and the second rod 142 at the first extreme position, and the solid lines represent the structural schematic diagrams of the first rod 141 and the second rod 142 at the second position. By limiting the angle α1 between the first rod 141 and the base 10 and the angle α2 between the second rod 142 and the base 10 to be acute angles, the tilt angle between the seat assembly 12 and the floor is limited, preventing the seat assembly 12 from tilting too much and reducing the impact force generated by seat adjustment, thus improving user comfort. Specifically, the distance between one end of the first rod 141 and one end of the second rod 142 should be greater than the distance between the other ends of the first rod 141 and the second rod 142 to ensure that α1 and α2 remain acute angles during the swinging process.

[0047] According to some embodiments of the present invention, the seat assembly 12 includes: a seat cushion 121, which is connected to the support assembly 11; a backrest 122, which is linked to the seat cushion 121, and the backrest 122 moves relative to the seat cushion 121 to adjust the shape of the seat assembly 12, and the backrest 122 is connected to the support assembly 11; the seat assembly 1 also includes: a second adjustment mechanism 132, which is disposed between the seat cushion 121 and the support assembly 11 and / or between the backrest 122 and the support assembly 11, and the second adjustment mechanism 132 is adapted to drive the seat cushion 121 and / or the backrest 122 to move.

[0048] Specifically, the seat assembly 12 includes a seat cushion 121 and a backrest 122, which are linked together. Adjusting the fore-and-aft position of the seat cushion 121 via the second adjustment mechanism 132 causes the backrest 122 to tilt accordingly, improving the convenience of seat adjustment. The second adjustment mechanism 132 can be located between the seat cushion 121 and the support assembly 11, or it can be located between the backrest 122 and the support assembly 11. For example, when the second adjustment mechanism 132 is located between the seat cushion 121 and the support assembly 11, the second adjustment mechanism 132, the seat cushion 121, and the support assembly 11 can move relative to each other via a slide rail or gear mechanism, thereby adjusting the fore-and-aft position of the seat cushion 121. During the movement of the seat cushion 121, the backrest 122 moves in tandem with the seat cushion 121 and tilts relative to the support assembly 11. When the seat cushion 121 moves forward, it can cause the backrest 122 to tilt backward, making it easier for the user to lie down on the seat. When the seat cushion 121 moves backward, the backrest 122 tilts forward relative to the support assembly 11, making it easier for the user to sit upright. Of course, the second adjustment mechanism 132 can also be located between the backrest 122 and the support assembly 11, with the adjustment principle of the seat cushion 121 and the backrest 122 being the same. By setting the second adjustment mechanism 132 between the seat cushion 121 and the support assembly 11 and / or between the backrest 122 and the support assembly 11, multi-directional adjustment of the seat assembly 12 can be achieved, improving passenger comfort and safety.

[0049] According to some embodiments of the present invention, the support assembly 11 includes: a first fixing plate 111 and a second fixing plate 112. One side of the first fixing plate 111 is connected to the first adjustment mechanism 131, and the second fixing plate 112 is connected to the first fixing plate 111 and to the backrest 122. The second adjustment mechanism 132 includes: a first guide rail 161, which is disposed on the other side of the first fixing plate 111 and extends along the length direction of the vehicle. A first sliding portion 164 is formed at the bottom of the seat cushion 121 to cooperate with the first guide rail 161; a second guide rail 162, which is disposed on the second fixing plate 112 and extends along the length direction of the second fixing plate 112. A second sliding portion 165 is disposed on the backrest 122 to cooperate with the second guide rail 162; and a second drive motor 152, which is disposed on the first guide rail 161 and is adapted to drive the first sliding portion 164 and / or the second sliding portion 165.

[0050] like Figures 1 to 5As shown, the support assembly 11 includes a first fixing plate 111 and a second fixing plate 112 connected to each other. The first fixing plate 111 supports the bottom of the seat cushion 121, and the second fixing plate 112 supports the rear side of the backrest 122. The tilt angle of the seat cushion 121 and the backrest 122 relative to the floor can be adjusted by adjusting the tilt angle of the first fixing plate 111 relative to the floor. The adjustment method is simple and convenient. The adjustment of the backrest 122 does not require a separate angle adjuster or drive motor, saving the overall cost of the seat assembly 1. The side of the first fixing plate 111 facing away from the seat cushion 121 is connected to the first adjustment mechanism 131. The first rod 141 and the second rod 142 of the first adjustment mechanism 131, the first fixing plate 111, and the floor form a four-bar linkage structure. The first rod 141 and the second rod 142 are driven to swing by the first adjustment mechanism 131 to adjust the tilt angle of the seat assembly 12. The second fixing plate 112 is connected to the first fixing plate 111, providing additional support and stability. A first guide rail 161 is provided on the side of the first fixed plate 111 facing the seat cushion 121, and the first guide rail 161 extends along the length direction of the vehicle. The first guide rail 161 cooperates with a first sliding part 164 at the bottom of the seat cushion 121, allowing the seat cushion 121 to slide along the length direction of the vehicle through the cooperation between the first sliding part 164 and the first guide rail 161, thereby realizing the adjustment of the position of the seat cushion 121. A second guide rail 162 is provided on the second fixed plate 112, and the second guide rail 162 extends along the length direction of the second fixed plate 112. The second guide rail 162 cooperates with a second sliding part 165 on the backrest 122, and the backrest 122 moves along the second guide rail 162 through the second sliding part 165, thereby realizing the adjustment of the position of the backrest 122. The second drive motor 152 is mounted on the first guide rail 161. The second drive motor 152 drives the first sliding part 164 to move along the extension direction of the first guide rail 161 to adjust the fore-and-aft position of the seat cushion 121. During the movement of the seat cushion 121, the backrest 122 is linked to the seat cushion 121 and drives the second sliding part 165 to move along the second guide rail 162, thereby adjusting the tilt angle of the backrest 122. For example, when the seat cushion 121 moves forward, it will cause the backrest 122 to tilt backward; when the seat cushion 121 moves backward, it will cause the backrest 122 to tilt forward. Through the cooperation between the first guide rail 161 and the first sliding part 164, and the second guide rail 162 and the second sliding part 165, the seat cushion 121 and the backrest 122 can be linked, ensuring that the positions of both the seat cushion 121 and the backrest 122 are adjustable, thus improving the comfort of the seat assembly 1. The second drive motor 152 is mounted on the first guide rail 161, making the arrangement of the second drive motor 152, the first sliding part 164, and the first guide rail 161 more compact and saving the arrangement space of the second drive motor 152. The second drive motor 152 drives the seat cushion 121 to move back and forth and drives the backrest 122 to move, making the adjustment process of the seat cushion 121 and the backrest 122 more automated and convenient, and improving the user's riding experience.

[0051] According to some embodiments of the present invention, the seat assembly 12 further includes a connecting part 123, one end of which is fixedly connected to the seat cushion 121, and the other end is hingedly connected to the backrest 122. The hinge connection point between the connecting part 123 and the backrest 122 is spaced apart from the end of the backrest 122 facing the seat cushion 121.

[0052] like Figures 1 to 5 As shown, a connecting part 123 is provided between the seat cushion 121 and the backrest 122. One end of the connecting part 123 is fixedly connected to the seat cushion 121, and the other end of the connecting part 123 is hinged to the backrest 122. When the seat cushion 121 moves back and forth, the backrest 122 moves in conjunction with the seat cushion 121. The hinge connection point between the connecting part 123 and the backrest 122 allows the backrest 122 to adjust its tilt angle, thereby realizing the angle adjustment of the backrest 122. The hinge connection point between the connecting part 123 and the backrest 122 is spaced apart from the end of the backrest 122 facing the seat cushion 121, so that the end of the backrest 122 protrudes from the hinge connection point between the backrest 122 and the connecting part 123. When the user adjusts the seat cushion 121 to move forward, the backrest 122 tilts backward. At this time, the bottom end of the backrest 122 will protrude from below the side panel and rotate upward around the hinge connection point, thereby supporting the user's waist and improving comfort.

[0053] In some embodiments, the connecting portion 123 may be configured as an arc, extending from the seat cushion 121 toward the backrest 122 and protruding toward the rear of the seat cushion 121. This allows for better adaptation to the curves of the human body, particularly the natural curvature of the spine, thereby providing better support, reducing pressure points during prolonged sitting, and improving seating comfort. Visually, the lines of the arc-shaped connecting portion 123 are smoother and softer than straight lines, enhancing the overall aesthetics of the seat assembly 1.

[0054] According to some embodiments of the present invention, the seat assembly 1 further includes a third guide rail 163, which is disposed on the floor and slidably connected to the first adjustment mechanism 131, and extends along the length of the vehicle.

[0055] like Figures 1 to 5As shown, a third guide rail 163 is provided on the vehicle floor. The third guide rail 163 extends along the length of the vehicle and is slidably connected to the first adjustment mechanism 131. By providing the third guide rail 163 to the first adjustment mechanism 131, the entire seat assembly 1 (including the seat cushion 121, backrest 122, and support assembly 11) can slide back and forth inside the vehicle to accommodate the height and seating posture needs of different passengers. A third drive motor 153 can be provided on the floor or on the third guide rail 163. When the seat position needs to be adjusted, the third drive motor 153 drives the first adjustment mechanism 131 to slide along the third guide rail 163, thereby moving the entire seat assembly 1 along the length of the vehicle. By adding the third guide rail 163, the seat assembly 1 can move as a whole along the length of the vehicle, allowing both the front and rear seats to move flexibly. Especially for MPV models, the addition of the third guide rail 163 allows for flexible movement of the front, middle, and rear seats to accommodate the height and seating posture needs of different passengers, improving comfort.
