[0002] Car seats are an essential component of automobiles, and car seat rails are an important functional part of car seats, allowing drivers to adjust the seat according to their driving habits, primarily adjusting the fore-and-aft position. The main components of the car seat rail linkage locking mechanism include the left and right rails, each composed of an inner rail and an outer rail. The inner rail is installed inside the outer rail and is unlocked or locked via a locking mechanism.

[0003] Chinese utility model patent CN217553746U discloses a locking structure for an automotive seat slide rail, relating to the technical field of automotive seat structures. The structure includes a base rail and a slide rail, with the slide rail horizontally slidably connected to the base rail. A locking ring is hung on the slide rail, with one end of the locking ring tightly inserted into the slide rail. The base rail has several locking blocks evenly distributed along its own direction of movement. A front top plate is located on one side of each locking block, with its top surface flush with the top surface of the locking block. The front top plate extends from one end of the locking ring towards the other end of the locking ring, and its front end is higher than the center of the locking ring.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-6 Existing automotive seat sliding rail linkage locking structures are inconvenient for preventing jamming, detachment, and quick connection during movement. To solve this technical problem, this embodiment discloses the following technical content.

[0030] The upper surface of the base 1 has a first storage groove 2 in the middle, and several racks 3 are fixedly connected at equal intervals from left to right on the front and rear ends of the upper surface of the base 1. The bottom of the base 1 has a second storage groove 4 in the middle, and several slots 5 are fixedly connected at equal intervals from left to right on the upper rear side of the base 1. The bottom of the rear side of the base 1 has a set of sliding grooves 6 in the middle, and a moving mechanism is slidably connected to the upper outer side of the base 1. The moving mechanism is composed of a moving plate 7, mounting holes 8, side plates 9, sliders 10 and a third storage groove 11. The lower surface of the moving plate 7 is in contact with the upper surface of the racks 3, and mounting holes 8 are provided at all four corners of the moving plate 7. The lower surface of the moving plate 7 is fixedly connected to the front and rear ends of the lower surface of the moving plate 7. The inner side of the side plate 9 is in contact with the outer side of the base 1. The slider 10 is fixedly connected to the middle of the lower surface of the moving plate 7, and the third storage groove 11 is provided in the middle of the moving mechanism.

[0031] The seat is fixed to the moving plate 7 by passing the bolt through the mounting hole 8 on the moving plate 7. When the seat is moved, the slider 10 on the lower surface of the moving plate 7 is slidably connected in the first storage groove 2. The side plate 9 restricts the moving plate 7 to prevent the moving plate 7 from falling off the base 1. Since the bottom front side of the slider 10 has a semi-circular structure, the moving plate 7 moves more smoothly and will not get stuck.

[0032] A connecting mechanism is provided at the rear center of the base 1 and the moving mechanism. The connecting mechanism is composed of a connecting rod 12, a handle 13, a first locking block 14, a crossbar 15, a second locking block 16, a moving block 17, a moving wheel 18, a spring 19, and a fixing plate 20. The handle 13 is fixedly connected to the rear center of the connecting rod 12, and a set of first locking blocks 14 are fixedly connected to the upper and lower ends of the front side of the connecting rod 12. A crossbar 15 is fixedly connected to the upper inner end of each of the first locking blocks 14. A second locking block 16 is fixedly connected to the front center of the connecting rod 12. The front end of 6 is engaged with the slot 5. A moving block 17 is provided on the outer side of the first locking block 14 at the lower end of the connecting rod 12. The four corners of the front side of the moving block 17 are fixedly connected with moving wheels 18, and the moving wheels 18 are slidably connected in the slide groove 6. A spring 19 is fixedly connected to the middle of the rear side of the moving block 17. A fixing plate 20 is fixedly connected to the bottom front side of the connecting rod 12. The first locking block 14 at the upper front side of the connecting rod 12 is slidably connected in the third storage slot 11, and the first locking block 14 at the lower front side of the connecting rod 12 is slidably connected in the first storage slot 2.

[0033] To adjust the position of the car seat, hold the handle 13 and pull the connecting mechanism towards the rear of the base 1, moving the first locking block 14 at the front end to the rearmost position. Since the front ends of the second and third storage compartments 4 and 11 represent the maximum movable range of the first locking block 14, after the first locking block 14 at the front end moves to the rearmost position, the spring 19 is stretched. At this time, the first locking block 14 is positioned between the front and rear racks 3. When the user sits on the car seat and moves the car seat back and forth, the moving plate 7 moves on the base 1. When adjusting the position of the moving plate 7, the lower first locking block 14 and the crossbar 15... It will move laterally within the second storage slot 4. The moving wheel 18 on the front side of the moving block 17 will slide within the slide groove 6. After the position is adjusted, the moving plate 7 needs to be fixed on the base 1. At this time, release the handle 13, and the spring 19 will return to its original state, which will move forward with the connecting rod 12 and the fixing plate 20, so that the first locking block 14 at the front end engages between the front rack 3. At the same time, the second locking block 16 engages with the corresponding slot 5. At this time, the moving plate 7 is fixed in a certain position on the base 1. The above are the steps to fix the moving plate 7 on the base 1 after adjusting the position of the moving plate 7.
