[0002] The existing seat adjustment structure usually has an upper slide rail slidably provided on the lower slide rail, and the seat frame is installed on the upper slide rail. The seat is adjusted by moving the upper slide rail along the lower slide rail and rotating the seat frame. Since the seat frame is fixed to an upper slide rail, the adjustment range of the seat is greatly limited, making it difficult to meet the passengers' needs for comfort.

[0003] The existing publication number CN113246817A discloses an adjustment structure and adjustment method of a car seat, including: a lower slide rail relatively arranged and fixedly installed on the bottom plate of the vehicle body; a first upper slide rail and a second upper slide rail slidably arranged on the lower slide rail, the second upper slide rail being located near the backrest of the seat; a first connecting rod having one end rotationally connected to the first upper slide rail and the other end rotationally connected to the end of the seat frame away from the backrest; and a second connecting rod having one end rotationally connected to the second upper slide rail and the other end connected to the end of the seat frame near the backrest, by moving the first upper slide rail back and forth along the lower slide rail to drive the first connecting rod to rotate, and tilt the seat frame, thereby changing the angle between the seat frame and the bottom plate of the vehicle body. By arranging two upper slide rails on one lower slide rail to expand the adjustment range of the seat, not only the functionality of the seat can be improved, but also the comfort requirements of passengers can be met.

[0004] However, the adjustment structure and adjustment method of the above-mentioned automobile seat, when it is necessary to adjust the seat height, move the first upper slide rail and the second upper slide rail along the lower slide rail in the direction of approaching or moving away from each other, and at the same time adjust the angle between the second connecting rod and the seat frame through the angle adjustment piece, so that the first upper slide rail and the second upper slide rail are moved closer to or away from each other, and the rise and fall of the seat frame are adjusted.

[0026] According to this specific embodiment, the reducer 103 is detachably connected to the seat frame 101 and is located at one end of the seat frame 101. The output end of the drive motor 102 is connected to the reducer 103, and the output end of the reducer 103 is connected to the lead screw 104. The sliding cylinder 105 is connected to the lead screw 104. There are two V-shaped connecting members, which are arranged opposite to each other, and one of the V-shaped connecting members is connected to the sliding cylinder 105. The seat frame 101 is used for support, and the driving motor 102 is driven to move by the control module 202, and the screw 104 is driven to rotate through the transmission of the reducer 103. The screw 104 is provided with a screw nut, and the sliding cylinder 105 is connected to the screw nut of the screw 104. According to the forward and reverse rotation of the screw 104, the sliding cylinder 105 moves along the screw 104. There are two V-shaped connecting members, which are used to connect the seat frame 112, and the seat frame 112 is covered with a leather (PU or imitation suede) to form a seat. One of the V-shaped connecting members is connected to the sliding cylinder 105, and is expanded or contracted according to the movement of the sliding cylinder 105.

[0027] Among them, one end of the first lower rod 106 is rotatably connected to the seat frame 101, and the other end of the first lower rod 106 is connected to the sliding cylinder 105. The first lower rod 106 is located at the end of the seat frame 101 away from the reducer 103; the second lower rod 108 is rotatably connected to the seat frame 101 and is located at the end of the seat frame 101 away from the first lower rod 106; the first upper rod 109 is rotatably connected to the first lower rod 106 and is located at the side of the first lower rod 106 away from the sliding cylinder 105. The two ends of the first cross bar 107 are rotatably connected to the first upper rod 109 and the second lower rod 108 respectively. When the sliding cylinder 105 moves outward, it pushes the first lower rod 106 to rotate from bottom to top along the seat frame 101, drives the first upper rod 109 to move upward, drives the first cross bar 107 to move upward, and the second lower rod 108 at the other end of the first cross bar 107 rotates accordingly.

At this time, the other side is relatively The V-shaped connecting rod components are configured to undergo the same deformation. The V-shaped connecting rod components are unfolded, and the seat is lifted. When the drive motor 102 drives the lead screw 104 to reverse, the sliding cylinder 105 moves inward, thereby driving the first lower rod 106 to reverse, the V-shaped connecting component contracts, and the seat is lowered. After the position adjustment is completed, the drive motor 102 stops rotating, and the sliding cylinder 105 is locked in position on the lead screw 104, thereby fixing the seat position. The two V-shaped connecting rod components jointly support the seat, which is more stable to use, and has a simple structure and is easy to use.
