[0001] The invention relates to the technical field of automobile accessories, in particular to a guide rail structure of an automobile seat provided with an adjustment mechanism. Background Art

[0002] The origin of car seat rail technology can be traced back to the early days of the automobile industry. With the development of the automobile industry, consumers' requirements for car riding comfort and convenience have continued to increase, and car seat rail technology has also been continuously upgraded. From the initial manual adjustment to the current electric adjustment, and even the integration of intelligent functions, the development of car seat rail technology has witnessed the progress of the automobile industry and the changes in consumer demand; The Chinese announcement number is: CN116442875B, which discloses an adjustable car seat, including a car seat and a connecting pillow, wherein the connecting pillow is installed on the top of the car seat; a headrest adjustment mechanism, wherein the car seat is provided with a headrest adjustment mechanism; and a lower inflation mechanism, wherein a lower inflation mechanism is provided between the car seat and the headrest adjustment mechanism. This patent can adjust the height of the headrest by rotating the adjustment rod, thereby protecting the heads of drivers of different heights, and when the driver sits on the pressing plate, the inflatable airbag can be expanded, thereby supporting the driver's waist and preventing the driver's waist from being suspended in the air, thereby improving the driver's comfort; Although the above patent uses an inflatable mechanism, an adjustment rod and other components to support the driver's waist and prevent the driver's waist from being suspended in the air, thereby improving the driver's comfort, it is considered that when the car seat is hit hard, the generator is damaged and the car machine cannot operate normally. At this time, the electric seat cannot be adjusted. Then, after an accident, it will be difficult for the driver or other passengers to adjust the seat for rescue when they are squeezed, which may easily lead to untimely rescue. In view of this, we propose a guide rail structure of a car seat with an adjustment mechanism. Summary of the invention

[0021] The sliding rod 232 is a hydraulic rod that slides in the arched hole 231 in the first sliding frame 23 , and the lower end of the sliding rod 232 abuts against the seat track bracket 12 .

[0022] like Figure 5-Figure 6As shown, the No. 1 turntable 24 is slidably connected to the No. 2 turntable 25 on the side close to the No. 1 fixed rod 242, and the No. 2 turntable 25 is provided with a strip groove 251 on the side close to the No. 1 fixed rod 242, and the width of the strip groove 251 matches the width of the No. 1 fixed rod 242.

[0023] like Figure 7-Figure 8 As shown, an adjuster handle 31 is provided in the opening assembly 3, and the adjuster handle 31 is rotatably connected to a No. 2 connecting rod 32 through a rotating column, and the No. 2 connecting rod 32 is rotatably connected to a No. 2 fixing rod 321 at the end away from the adjuster handle 31, and the No. 2 fixing rod 321 is fixedly connected between the seat track brackets 12 on both sides, and the No. 2 connecting rod 32 is rotatably connected to a No. 3 connecting rod 33 at the end away from the seat track bracket 12, and the No. 3 connecting rod 33 is rotatably connected to a No. 4 connecting rod 34 at the end away from the No. 2 connecting rod 32, and the No. 4 connecting rod 34 is fixedly connected to a toggle rod 35 at one end away from the No. 3 connecting rod 33, and the toggle rod 35 is located above the triangle 114, and the No. 3 connecting rod 33 is slidably connected to the surface of the seat track partition 11, and the No. 3 connecting rod 33 passes through the seat track partition 11.

[0024] It can be seen from this that after a major accident, when the vehicle is damaged and the seat cannot be moved and needs to be adjusted for rescue, Figure 2-Figure 3 As shown, after the passenger or driver sits on the seat, the seat is pressed down by the pressure on the top plate 13. At this time, the sliding rod 232 slides downward in the No. 1 sliding frame 23 until the top plate 13 and the top of the No. 1 sliding frame 23 are in contact with each other and then stop. At this time, the upper and lower ends of the No. 1 sliding frame 23 are both blocked by the top plate 13 and the fixing block 112 in the slide rail 111 and cannot move. At this time, after a car accident or damage to the vehicle, it is necessary to rescue the passenger or driver and adjust the seat position. The rescuer pulls the adjuster handle 31, as shown in FIG. Figure 7As shown, at this time, the adjuster handle 31 moves to the right side, and drives the No. 3 connecting rod 33 to rotate counterclockwise by a certain angle. At the same time, the No. 3 connecting rod 33 drives the No. 4 connecting rod 34 to press down, and drives the toggle rod 35 to move down. During the downward movement of the toggle rod 35, it will resist and push the inclined surface of the triangular member 114, so that the triangular member 114 and the sliding plate 113 slide a short distance to the left. At this time, the inclined surface of the triangular member 114 will drive the No. 1 sliding frame 23 to move up. At this time, the No. 1 sliding frame 23 will be restricted by the oblique No. 1 fixing rod 242 during the upward movement, and the No. 2 sliding frame 252 will slide in the direction of the inclination direction of the No. 1 fixing rod 242.

At this time, when the vehicle machine cannot operate, the seat can slide to one side by a certain distance to facilitate rescue by rescue personnel; It should be noted that, under the drive of the motor 21, the threaded rod 22 rotates, and the threaded rod 22 rotates to drive the sliding block 222 to slide to one side. In the process of sliding the sliding block 222 to one side, the No. 1 connecting rod 223 is driven to rotate, and the No. 1 turntable 24 is driven to rotate in the process of the No. 1 connecting rod 223 rotating. At this time, the rotation angle of the No. 1 fixed rod 242 is the same as the rotation angle of the No. 1 connecting rod 223. Then, the No. 2 sliding frame 252 sliding under the restriction of the strip groove 251 on the No. 2 turntable 25 will change due to the change of the inclination angle of the No. 1 fixed rod 242. When the angle formed between the No. 1 fixed rod 242 and the No. 1 sliding frame 23 is larger, the sliding distance of the No. 2 sliding frame 252 is larger, and vice versa. When the whole device is completely relaxed, the triangle member 114 and the sliding plate 113 return to the initial position under the action of the spring 1121, and the No. 1 sliding frame 23 and the No. 2 sliding frame 252 return to the initial position together.
