The two limit assemblies 32 each include two L-shaped connecting vertical rods 321, and the inner sides of the two groups of L-shaped connecting vertical rods 321 close to each other are fixedly connected with a clamping plate 322. The inner sides of the two clamping plates 322 extend to the inner sides of the two Z-shaped guide plates 313 through the bottom of the Z-shaped guide plate 313 and fit with the inner walls of the two limiting grooves 3114 opened on the sliding vertical plate 3113. The tops of the two groups of L-shaped connecting vertical rods 321 away from the clamping plate 322 are fixedly connected to the limiting plate 323. The outer walls are slidably connected to the inner walls of the two limit plate slide plates 315 respectively. The inner walls of the two limit plates 323 are fixedly connected to a plurality of fitting rod guide blocks 326 on one side near the card plate 322. One side of the two groups of fitting rod guide blocks 326 is fixedly connected to a spring connecting block 327. The inner walls of the two groups of fitting rod guide blocks 326 are slidably connected to fitting rods 328. The tops of the two groups of fitting rods 328 are provided with fitting rod sliding grooves 329. The inner walls of the fitting rod sliding grooves 329 provided by the two groups of fitting rods 328 are fixedly connected to springs 3211. One end of the two groups of springs 3211 close to the spring connecting block 327 is fixedly connected to the spring connecting block 327. The two groups of fitting rods 328 are fixedly connected to the fitting block 3210 on one side near the card plate 322.When the locking cam 322 is unlocked, the locking cam 324 is unlocked, and the winch cam 328 is unlocked, and the winch cam 328 is unlocked. The winch cam 328 is unlocked, and the winch cam 328 is unlocked. The dust mechanism 4 includes a dust collection box 41. The outer sides of the two groups of dust collection boxes 41 are fixedly connected to two pipes 42. The ends of the multiple groups of pipes 42 away from the dust collection box 41 are fixedly connected to a dust collection plate 43. The front and rear sides of the bottoms of the two dust collection plates 43 are fixedly connected to arc-shaped rotating rods 44. The middle parts of the two groups of arc-shaped rotating rods 44 are rotatably connected to hinge blocks 45. The inner sides of the two groups of hinge blocks 45 are respectively fixedly connected to the front and rear sides of the outer sides of the two limiting plates 323. The inner bottoms of the two groups of arc-shaped rotating rods 44 are rotatably connected to two-way hinge blocks 46. The inner sides of the two groups of two-way hinge blocks 46 are respectively fixedly connected to the front and rear sides of the outer sides of the two expansion plates 324.

[0038] When the user needs to adjust the position of the seat 1, the user presses the main pressure rod 2 downward. When the main pressure rod 2 is pressed downward, the two pressure rods 318 are driven to move downward. When the two pressure rods 318 move downward, they push the two rotating rod hinge blocks 319 to move downward. Since the inclinations of the two rotating rods 3110 are opposite, the two rotating rods 3110 will rotate in opposite directions under the push of the rotating rod hinge blocks 319, thereby driving the two sliders 3112 to slide left and right on the inner wall of the horizontal sliding groove rod 3111. As the slider 3112 slides, the two expansion plate connecting blocks 325 also move accordingly. Since the expansion plate connecting block 325 is fixedly connected to the front side of the expansion plate 324, the expansion plate 32 4 realizes the contraction and expansion action. When the contraction and expansion plate 324 moves to fit with the L-shaped connecting rod 321, the L-shaped connecting rod 321 will move with the movement of the contraction and expansion plate 324. Since the inner wall of the limiting plate 323 is connected to the spring connecting block 327 through the fitting rod 328 and the spring 3211, when the limiting plate 323 moves, the fitting rod 328 will slide on the inner wall of the fitting rod guide block 326. At the same time, the spring 3211 is deformed to provide a reset force, so that the two limiting plates 323 and the multiple fitting rods 328 on the inner wall and the fitting block 3210 on one side are separated from the outer wall of the inverted T-shaped connecting block 3115. The two clamping plates 322 move with the two groups of L-shaped connecting rods 321 to separate from the two openings opened by the sliding plate 3113 The inner wall of the limiting groove 3114, at this time, the sliding vertical plate 3113 and the inverted T-shaped connecting block 3115 are released from the limit, and the user can pull the seat 1 forward or backward. Under the action of the pulling force, the seat 1 drives the inverted T-shaped connecting block 3115 to slide on the inner side of the two Z-shaped guide plates 313. At the same time, the inverted T-shaped connecting block 3115 drives the sliding vertical plate 3113 to slide on the inner side of the two Z-shaped guide plates 313. During the sliding process of the sliding vertical plate 3113, the multiple rollers 312 at the bottom of the sliding vertical plate 311 roll on the top of the bottom plate 311, reducing the friction between the sliding vertical plate 3113 and the bottom plate 311, which facilitates the sliding of the seat 1. When the seat 1 is released from the limit, the two retracting and expanding plates 324 move outward, thereby bringing The two sets of bidirectional hinge blocks 46 are moved outward to push the two sets of arc-shaped rotating rods 44 to rotate with the two sets of hinge blocks 45 as the axis, thereby driving the two dust collection plates 43 to rotate to form a V-shaped structure. At this time, the two dust collection boxes 41 start to work. During the rotation process, the two dust collection plates 43 can suck the dust and impurities that fall from the bottom of the seat 1 when it moves into the dust collection box 41, so as to prevent the dust and impurities from affecting the movement of the seat 1. At the same time, the cleanliness of the track is ensured to prevent dust and impurities from accumulating for a long time, which makes it difficult for the bottom of the seat 1 to slide. When the seat 1 is not sliding, the two dust collection plates 43 are in a parallel state and are located on both sides of the bottom of the seat 1. They vacuum the dust and impurities that usually fall around the seat 1 to ensure the cleanliness of the floor of the commercial vehicle.

[0039] When the seat 1 slides to a suitable position, the user pulls the main pressure rod 2 upward, and the main pressure rod 2 drives the two pressure rods 318 to move upward. In the process of the pressure rod 318 moving upward, the rotating rod hinge block 319 moves upward. In the process of the rotating rod hinge block 319 moving upward, the two rotating rods 3110 are respectively pulled to rotate in opposite directions to reset. In the process of the two rotating rods 3110 rotating, the two sliders 3112 slide left and right on the inner wall of the horizontal sliding groove rod 3111 to reset. In the process of sliding and resetting, the two sliders 3112 drive the two expansion plate connecting blocks 325 to move back and forth. When the two expansion plate connecting blocks 325 move and reset, they drive the two L-shaped connecting vertical rods 321 and the expansion plate 324 to slide and reset on the inner wall of the expansion plate slide plate 314. When the two expansion plates 324 slide and reset, they drive the two two-way hinge blocks 46 to move inward. When the two two-way hinge blocks 46 move, they respectively push the two arc-shaped rotating rods 44 to rotate and reset with the two hinge blocks 45 as the axis. When the two arc-shaped rotating rods 44 rotate and reset, they drive the two dust collecting plates 43 to rotate and reset to a parallel state. At this time, the fitting rod 328 moves toward the direction of the card plate 322. When the fitting block 3210 moves, the fitting blocks 3210 on both sides of the inverted T-shaped connecting block 3115 will automatically adapt to fit the outer wall of the inverted T-shaped connecting block 3115 under the action of the spring 3211 and the second spring 3212. The fitting blocks 3210 on the other side of the fitting rod 328 fit together to seal the middle of the two Z-shaped guide plates 313, ensuring that debris will not fall on the inner side of the two Z-shaped guide plates 313. The two clamping plates 322 are clamped into the inner walls of the two limiting grooves 3114 opened on the sliding plate 3113 under the action of the two L-shaped connecting rods 321. At this time, the sliding plate 3113 The vertical plate 3113 and the inverted T-shaped connecting block 3115 are re-limited to complete the adjustment of the position of the seat 1. After the position adjustment of the seat 1 is completed, the screw rod is inserted into the guide block 317 and the inner wall of the pressure rod 318 to fix the position of the pressure rod 318. The entire adjustment process is smooth and smooth, and the design of the dust collection plate 43 effectively ensures the cleanliness of the interior of the commercial vehicle, thereby improving the user's riding experience. In addition, the seat track linkage mechanism and the stopping method are compact in structure, easy to operate, and have high practicality and reliability. They are suitable for various commercial vehicle models and provide a new solution for seat adjustment of commercial vehicles.

[0040] In addition, the present invention also relates to a method for stopping a seat track linkage mechanism of a commercial vehicle, comprising the following steps:

[0041] Step 1: When the position of seat 1 needs to be adjusted, first ensure that the commercial vehicle is stationary to ensure the safety of the operation, and then perform the following steps;

[0042] Step 1: To unlock the seat 1, the user pulls up the main pressure rod 2, which, through a series of mechanical linkages, disengages the latch plate 322 that was originally engaged in the limiting groove of the sliding upright plate at the bottom of the seat 1, thereby unlocking the seat 1. During this process, the pressure rod 318, the rotating rod 3110, the slider 3112, and the retractable plate 324 work together to convert the seat 1 from a fixed to a slidable state.

[0043] Step 2: Adjust the position of the seat 1. After the seat 1 is unlocked, the user can easily move the seat 1 to the desired position as needed. The slide rail is designed with rollers 312, which effectively reduces the friction during movement, making the adjustment process of the seat 1 smoother.

[0044] Step 3: Relock the seat 1. When the seat 1 is moved to the appropriate position, the user operates the main pressure rod 2 again to return it to its initial position. At this time, the clamping plate 322 and the limit plate 323 and the multiple fitting rods 328 and fitting blocks 3210 inside them re-lock the inverted T-shaped connecting block 3115 and the sliding vertical plate 3113. In this process, the fitting blocks 3210 on both sides of the inverted T-shaped connecting block 3115 will automatically adapt to fit on the outer wall of the inverted T-shaped connecting block 3115 under the action of the spring 3211 and the second spring 3212. The fitting blocks 3210 on one side of the remaining fitting rods 328 fit together to close the middle of the two Z-shaped guide plates 313 to ensure that debris will not fall on the inner side of the two Z-shaped guide plates 313.

[0045] The working principle of the present invention is as follows: when the position of the seat 1 needs to be adjusted, the user presses the main pressure rod 2 downward. When the main pressure rod 2 is pressed downward, the two pressure rods 318 are driven to move downward. When the two pressure rods 318 move downward, they push the two rotating rod hinge blocks 319 to move downward respectively. Since the inclinations of the two rotating rods 3110 are opposite, the two rotating rods 3110 will rotate in opposite directions respectively under the push of the rotating rod hinge blocks 319, thereby driving the two sliders 3112 to slide left and right on the inner wall of the horizontal sliding groove rod 3111. As the slider 3112 slides, the two expansion plate connecting blocks 325 also move accordingly. Since the expansion plate connecting block 325 is fixedly connected to the front side of the expansion plate 324, the expansion plate 324 realizes the expansion and contraction action. When the locking plate 324 is unlocked, the locking plate 320 is unlocked, and the locking plate 320 is unlocked, so that the locking plate 320 can be unlocked. With the limit released by the inverted T-shaped connecting block 3115, the user can pull the seat 1 forward or backward. Under the action of the pulling force, the seat 1 drives the inverted T-shaped connecting block 3115 to slide on the inner side of the two Z-shaped guide plates 313. At the same time, the inverted T-shaped connecting block 3115 drives the sliding vertical plate 3113 to slide on the inner side of the two Z-shaped guide plates 313. During the sliding process of the sliding vertical plate 3113, the multiple rollers 312 at the bottom of the sliding vertical plate 311 roll on the top of the bottom plate 311, reducing the friction between the sliding vertical plate 3113 and the bottom plate 311, thereby facilitating the sliding of the seat 1. When the limit of the seat 1 is released, the two retracting and expanding plates 324 move outward, thereby driving the two sets of two-way hinge blocks 46 to move outward, thereby pushing the two sets of arc-shaped rotating rods 44 to move with the two sets of hinge blocks 45 The two dust collecting plates 43 rotate along the axis, thereby driving the two dust collecting plates 43 to rotate to form a V-shaped structure. At this time, the two sets of dust collecting boxes 41 start to work. During the rotation process, the two dust collecting plates 43 can suck the dust and impurities that fall from the bottom of the seat 1 when it moves into the dust collecting box 41, so as to prevent the dust and impurities from affecting the movement of the seat 1. When the seat 1 is not sliding, the two dust collecting plates 43 are in a parallel state and are located on both sides of the bottom of the seat 1. When the seat 1 slides to a suitable position, the user pulls the main pressure rod 2 upward, and the main pressure rod 2 drives the two pressure rods 318 to move upward. During the upward movement of the pressure rod 318, the rotating rod hinge block 319 is pulled upward. During the upward movement of the rotating rod hinge block 319, the two rotating rods 3110 are respectively pulled to rotate in opposite directions to reset.When the two rotating rods 3110 rotate, the two sliders 3112 slide left and right on the inner wall of the horizontal sliding groove rod 3111 and reset. When the two sliders 3112 slide and reset, the two expansion plate connecting blocks 325 move and reset. When the two expansion plate connecting blocks 325 move and reset, the two L-shaped connecting vertical rods 321 and the expansion plate 324 slide and reset on the inner wall of the expansion plate sliding groove plate 314. When the two expansion plates 324 slide and reset, the two two-way hinge blocks 46 move inward. When the two two-way hinge blocks 46 move, they push the two arc-shaped rotating rods 44 to rotate and reset around the two hinge blocks 45 as the axis. When the two arc-shaped rotating rods 44 rotate and reset, they drive the two dust collection plates 43 to rotate and reset to a parallel state. At this time, the fitting rod 328 moves toward the direction of the card plate 322. During the movement of the fitting blocks 3210, the fitting blocks 3210 on both sides of the inverted T-shaped connecting block 3115 will automatically adapt to fit on the outer wall of the inverted T-shaped connecting block 3115 under the action of the spring 3211 and the second spring 3212. The fitting blocks 3210 on the other side of the fitting rod 328 fit together to seal the middle of the two Z-shaped guide plates 313, ensuring that debris will not fall on the inner side of the two Z-shaped guide plates 313. The two clamping plates 322, under the action of the two L-shaped connecting rods 321, are clamped into the inner walls of the two limiting grooves 3114 opened on the sliding vertical plate 3113. At this time, the sliding vertical plate 3113 and the inverted T-shaped connecting block 3115 are re-limited, completing the adjustment of the position of the seat 1. After the position adjustment of the seat 1 is completed, the screw rod is inserted into the guide block (317) and the inner wall of the pressure rod 318 to fix the position of the pressure rod 318.
