For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0060] Furthermore, in the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0061] Figure 3 The image shown is a side view of the vehicle seat of this utility model. In the following description, it will be referred to as... Figure 3 The attached diagram serves as a reference for direction. Figure 3 In the diagram, the direction perpendicular to the view plane and facing outwards is defined as left; the direction perpendicular to the view plane and facing inwards is defined as right; the direction upwards along the view plane is defined as up; the direction downwards along the view plane is defined as down; the direction to the right along the view plane is defined as back; and the direction to the left along the view plane is defined as front. The width direction of the cushion 11 is defined as the front-to-back direction, and the length direction of the cushion 11 is defined as the left-to-right direction.

[0062] like Figures 1-3 As shown, this utility model provides a vehicle seat, which includes a seat cushion mechanism 1, a backrest 2, a backrest connecting mechanism 3, and a backrest sliding mechanism 4. The seat cushion mechanism 1 includes a seat cushion 11 with a seat cushion groove 111 extending along the width direction (i.e., the front-to-back direction) of the seat cushion 11. The backrest 2 is a separate component positioned above the seat cushion mechanism 1. The backrest connecting mechanism 3 includes a slider 31 passing through the seat cushion groove 111, with its top connected to the backrest 2. The backrest sliding mechanism 4 is positioned below the seat cushion mechanism 1 and drives the slider 31 to move along the seat cushion groove 111. Driven by the backrest sliding mechanism 4, the position of the backrest 2 in the width direction of the seat cushion 11 is adjustable; it can be positioned at the front or rear of the seat cushion 11, allowing the vehicle seat to face rearward or forward, enabling passengers to sit facing either direction.

[0063] Compared with the prior art, this utility model, by opening a seat cushion groove 111 on the seat cushion 11, allows the backrest sliding mechanism 4 to be placed under the seat cushion 11. The car seat can make fuller use of the space in the vertical direction and save the space occupied in the horizontal direction, making the overall structure more compact. At the same time, the sliding part 31 used to connect with the backrest 2 is accommodated in the seat cushion groove 111, reducing the exposed area of ​​the sliding part 31, making it less likely to accumulate dust, and the overall visual effect is more beautiful.

[0064] like Figures 4-5As shown, the backrest sliding mechanism 4 preferably includes a lead screw motor. The output shaft of the motor is connected to a lead screw 42, the extension direction of which is parallel to the width direction of the seat cushion 11. A slider 41 movably mounted on the lead screw 42 is connected to a sliding member 31. When the motor drives the lead screw 42 to rotate, the slider 41 drives the sliding member 31 to move along the lead screw 42, thereby realizing the fore-and-aft position adjustment function of the backrest 2. Those skilled in the art can also, as needed, use a gear and rack structure or a synchronous belt structure instead of the connection structure between the lead screw 42 and the slider 41, which can also convert the rotational motion output by the motor into the linear motion of the sliding member 31.

[0065] like Figures 1-3 As shown, the seat cushion mechanism 1 also includes a seat cushion support 12, and the seat cushion 11 is fixed to the seat cushion support 12. The seat cushion mechanism 1 can be configured as a fixed position or an adjustable front-to-back position. In one embodiment, the vehicle seat also includes a seat cushion sliding mechanism disposed below the seat cushion 11, which is used to drive the seat cushion mechanism 1 to move along the width direction of the seat cushion 11. The seat cushion sliding mechanism can adopt the same structure as the backrest sliding mechanism 4 described above, and will not be described again here.

[0066] like Figure 3 As shown, the backrest 2 includes two opposing backrest surfaces arranged along the width direction of the seat cushion 11. The two backrest surfaces can be arranged symmetrically or asymmetrically. Regardless of whether the backrest 2 is moved to the front or rear of the seat cushion 11, the passenger can lean against one of the backrest surfaces to obtain a good and comfortable riding experience.

[0067] Furthermore, to facilitate the adjustment of the angle between the backrest 2 and the seat cushion 11, the vehicle seat provided by this utility model also includes a backrest rotation mechanism 5 disposed between the sliding member 31 and the backrest sliding mechanism 4. The backrest rotation mechanism 5 is used to drive the sliding member 31 to rotate.

[0068] like Figures 3-5 As shown, the backrest rotation mechanism 5 includes a rotation limiting member 52 and a rotation driving member 51 respectively connected to the backrest sliding mechanism 4. The rotation limiting member 52 is provided with a first limiting protrusion 521 and a second limiting protrusion 522 distributed along the width direction of the seat cushion 11, wherein the first limiting protrusion 521 is located in front of the second limiting protrusion 522. The backrest connecting mechanism 3 also includes a rotating member 33 connected to the sliding member 31. The rotating member 33 rotates under the drive of the rotation driving member 51. The rotating member 33 is also provided with a limiting post 331, which is disposed between the first limiting protrusion 521 and the second limiting protrusion 522.

[0069] When the rotary drive 51 drives the slider 31 to rotate counterclockwise to the first preset angle, the limiting post 331 abuts against the first limiting protrusion 521, at which point the backrest 2 reaches its maximum forward tilt angle 'a', suitable for passengers to sit facing backward. When the rotary drive 51 drives the slider 31 to rotate clockwise to the second preset angle, the limiting post 331 abuts against the second limiting protrusion 522, at which point the backrest 2 reaches its maximum backward tilt angle 'b', suitable for passengers to sit facing forward. The angle of the backrest 2 can be adjusted between 'a' and 'b' to help passengers obtain a more comfortable riding experience. Preferably, the rotary drive 51 can be a stepper motor or a servo motor.

[0070] like Figures 1-4 As shown, the seat cushion 11 has one or more seating positions 112. Along the length direction (i.e., left-right direction) of the seat cushion 11, each seating position 112 has a seat cushion slot 111 on each side, and each seating position 112 is correspondingly provided with a backrest 2, a backrest connecting mechanism 3, a backrest sliding mechanism 4, and a backrest rotating mechanism 5. Each backrest connecting mechanism 3 includes two sliding members 31 and two rotating members 33. The two sliding members 31 are respectively disposed in the seat cushion slots 111 on both sides of each seating position 112. The top of both is connected to the same backrest 2, and the bottom of both are connected as a whole by a connector 32. Compared with a single sliding member 31, two sliding members 31 can more stably support the backrest 2 and drive the backrest 2 to move or rotate. The connector 32 is disposed below the seat cushion mechanism 1, and the two rotating members 33 are respectively disposed on the left and right sides of the bottom of the connector 32. The backrest sliding mechanism 4 includes a slider connecting plate 43 connected to the slider 41; each backrest rotation mechanism 5 includes two rotation limiting members 52, one rotation driving member 51, and one rotating shaft 511. The two rotation limiting members 52 are respectively arranged on the left and right sides of the slider connecting plate 43, and are arranged one-to-one with the two rotating members 33; the rotation driving member 51 is connected to one of the rotation limiting members 52, and is used to drive the rotating shaft 511 to rotate. The two ends of the rotating shaft 511 are respectively connected to the two rotating members 33. This arrangement makes the car seat a sofa that can accommodate multiple people sitting side by side, and the position and angle of the backrest 2 of each seat 112 can be adjusted independently, making it more flexible to use.

[0071] In another embodiment of this utility model, a backrest 2, a backrest connecting mechanism 3, a backrest sliding mechanism 4, and a backrest rotating mechanism 5 are correspondingly provided at a seat cushion mechanism 1. The seat cushion 11 has multiple seating positions 112, with a seat cushion slot 111 between each pair of adjacent seating positions 112. The backrest connecting mechanism 3 includes multiple sliding members 31, which are correspondingly arranged in the multiple seat cushion slots 111. Each backrest surface in the backrest 2 includes multiple backrest surfaces equal in number to the number of seating positions 112, and these backrest surfaces and seating positions 112 are correspondingly arranged. In this embodiment, the vehicle seat can form a sofa that allows multiple people to sit side-by-side. All seating positions 112 share a backrest 2, and the position and angle of the backrest 2 can be adjusted relative to the seat cushion 11. The overall structure is relatively simple and easy to install.

[0072] like Figures 6-8 As shown, to prevent dust from falling into the seat cushion slot 111, a zipper is installed inside the seat cushion slot 111. The zipper includes a first zipper strap 81 and a second zipper strap 82, and the zipper teeth of both are distributed along the width direction of the seat cushion 11. Meanwhile, the vehicle seat provided by this utility model also includes a zipper pull mounting component 6, which specifically has the following two embodiments.

[0073] In one embodiment of the zipper pull mounting component 6, the zipper pull mounting component 6 includes a mounting portion 61 with an opening 611, a first zipper pull 71 fixedly disposed at one end of the mounting portion 61, and a second zipper pull 72 fixedly disposed at the other end of the mounting portion 61. A sliding member 31 passes through the opening 611. The first zipper pull 71 and the second zipper pull 72 are distributed along the width direction of the cushion 11, and are located on the front and rear sides of the sliding member 31, respectively. The first zipper pull 71 and the second zipper pull 72 are slidably disposed between the first zipper tape 81 and the second zipper tape 82. The first zipper tape 81 and the second zipper tape 82 are separated from each other in the area between the first zipper pull 71 and the second zipper pull 72, and are joined together in the area other than the area between the first zipper pull 71 and the second zipper pull 72. This design does not affect the movement of the slider 31 in the seat cushion slot 111, and can also cover the seat cushion slot 111. It prevents dust or impurities from falling into the area of ​​the seat cushion slot 111 other than the area where the slider 31 is located, thus achieving a good dustproof and dirtproof effect, while also preventing passengers' hands from being accidentally caught in it.

[0074] like Figure 6 , Figure 9 and Figure 10As shown, the difference between Embodiment 2 and Embodiment 1 of the zipper pull mounting component 6 is that each end of the mounting part 61 is hinged to a connecting part 62, and the axis of rotation of the connecting part 62 is parallel to the length direction of the seat cushion 11; the first zipper pull is disposed in one of the connecting parts 62, and the second zipper pull is disposed in the other connecting part 62. That is, the first zipper pull and the second zipper pull are rotatably connected to the end of the mounting part 61 through a connecting part 62, and can swing up and down relative to the mounting part 61. Compared with Embodiment 1, the zipper pull mounting component 6 provided in Embodiment 2 provides a certain degree of freedom for the first zipper pull and the second zipper pull. This arrangement makes the two zipper pulls fit the zipper better when moving with the sliding member 31, and will not pull the surface of the seat cushion near the zipper, thus avoiding the sliding member 31 from getting stuck during its movement along the seat cushion groove 111, making the movement of the sliding member 31 smoother; it can also buffer when the backrest 2 rotates, preventing the zipper pull from detaching from the zipper due to external force.

[0075] The present invention also provides a vehicle, which includes a vehicle body, and the aforementioned vehicle seat is provided in the vehicle body. The backrest sliding mechanism 4 is embedded in the bottom of the vehicle body, and a shield is provided at the embedded opening to prevent dust from falling into the backrest sliding mechanism 4.

[0076] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
