[0037] The sliding rod 232 is a hydraulic rod sliding in the arcuate hole 231 of the first sliding frame 23, and the lower end of the sliding rod 232 abuts against the seat rail bracket 12.

[0038] As shown in the figure, Figures 5-6 The first rotary disc 24 is slidably connected with a second rotary disc 25 away from the first fixed rod 242, the second rotary disc 25 is provided with a strip-shaped groove 251 away from the first fixed rod 242, the width of the strip-shaped groove 251 is matched with the width of the first fixed rod 242, the second rotary disc 25 is slidably connected with the outer wall of the first fixed rod 242 through the strip-shaped groove 251, the first sliding frame 23 and the second sliding frame 252 are slidably connected with the seat rail bracket 12, the bottom of the first sliding frame 23 is in the same vertical plane with the slide rail 111, and the first sliding frame 23 is located on the top of the sliding plate 113.

[0039] As shown in the figure, Figures 7-8 The adjusting assembly 3 is provided with an adjuster handle 31, the adjuster handle 31 is rotatably connected with a second connecting rod 32 through a rotating column, the second connecting rod 32 is rotatably connected with a second fixed rod 321 away from the adjuster handle 31, the second fixed rod 321 is fixedly connected between the two seat rail brackets 12, the second connecting rod 32 is rotatably connected with a third connecting rod 33 away from the seat rail bracket 12, the third connecting rod 33 is rotatably connected with a fourth connecting rod 34 away from the second connecting rod 32, the fourth connecting rod 34 is fixedly connected with a pushing rod 35 away from the third connecting rod 33, and the pushing rod 35 is located above the triangular piece 114, the third connecting rod 33 is slidably connected with the surface of the seat rail partition plate 11, and the third connecting rod 33 penetrates through the seat rail partition plate 11.

[0040] Therefore, it can be seen that in the event of a major accident where the vehicle's infotainment system is damaged and the seat position cannot be moved, requiring adjustment for rescue, such as... Figures 2-3 As shown, after the passenger or driver sits in the seat, the pressure on the seat pushes down the top plate 13. At this time, the sliding rod 232 slides downwards within the first sliding frame 23 until the top plate 13 is in contact with the top of the first sliding frame 23 and stops. At this point, both the upper and lower ends of the first sliding frame 23 are blocked by the top plate 13 and the fixing block 112 inside the slide rail 111 and cannot move. At this time, in the event of a car accident or damage to the vehicle's machinery, if it is necessary to rescue the passenger or driver and adjust the seat position, the rescuer pulls the adjuster handle 31. Figure 7 As shown, at this time, the adjuster handle 31 moves to the right and drives the third link 33 to rotate counterclockwise by a certain angle. At the same time, the third link 33 will drive the fourth link 34 to press down and drive the lever 35 to move down. During the downward movement of the lever 35, it will abut against and push the inclined surface of the triangular piece 114, causing the triangular piece 114 and the sliding plate 113 to slide a small distance to the left. At this time, the inclined surface of the triangular piece 114 will drive the first sliding frame 23 to move up. During the upward movement of the first sliding frame 23, it will be restricted by the inclined first fixed rod 242, and the second sliding frame 252 will slide in the direction of the first fixed rod 242. It should be noted that the two ends of the second sliding frame 252 are connected to the bottom of the seat by welding. At this time, when the vehicle machine cannot operate, the seat can slide to one side a certain distance to facilitate rescue personnel.

[0041] It should be noted that, driven by the motor 21, the threaded rod 22 rotates. During the rotation of the threaded rod 22, the sliding block 222 will slide to one side. During the sliding of the sliding block 222 to one side, the first connecting rod 223 will rotate. During the rotation of the first connecting rod 223, the first turntable 24 will rotate. At this time, the rotation angle of the first fixed rod 242 is the same as the rotation angle of the first connecting rod 223. Therefore, the sliding frame 252, which slides under the restriction of the strip groove 251 on the second turntable 25, will change due to the change in the tilt angle of the first fixed rod 242. The larger the angle formed between the first fixed rod 242 and the first sliding frame 23, the greater the sliding distance of the second sliding frame 252, and vice versa.

[0042] When the entire device is fully relaxed, the triangular piece 114 and the sliding plate 113 return to their initial positions under the action of the spring 1121, while the first sliding frame 23 and the second sliding frame 252 return to their initial positions together.

[0043] The above shows and describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above-mentioned embodiments, and the above-mentioned embodiments and descriptions in the specification are only preferred examples of the present application and are not intended to limit the present application.
