[0002] With the increasing progress of society, cars have become a common means of transportation in people's lives. In the process of car use, car modification is becoming more and more popular. Some high-end commercial vehicles require various modifications to meet the needs of passengers.

[0003] According to Chinese Patent Publication No. CN221113613U, a vehicle seat lateral sliding guide mechanism includes a guide assembly having at least two sets of sliding guide channels; a slide rod assembly including slide rods, the number of which matches the number of the sliding guide channels, the slide rods being slidably installed in the sliding guide channels, and one surface of each slide rod having at least two pin holes; and a pin assembly including pins disposed at the slide rods with pin holes, the pins being selectively inserted into the pin holes. This lateral sliding guide mechanism enables lateral movement and locking of the seat, greatly enhancing the flexibility of seat use. This utility model also proposes a passenger car seat using the above-described vehicle seat lateral sliding guide mechanism.

[0004] Traditional manual or semi-automatic lateral sliding systems often rely on simple mechanical sliding mechanisms, making it difficult to achieve precise position control. This not only affects the accuracy of seat adjustment but may also cause inconvenience to passengers during use. Secondly, during vehicle operation, especially when encountering bumpy roads, the lateral sliding structure may become loose or shaky, reducing the stability of the seat and the safety of the ride. In addition, external impacts (such as sudden braking) may also cause the seat to shift unexpectedly. Utility Model Content

[0005] The purpose of this utility model is to provide a transverse sliding structure for an automotive seat bracket and its rail connection structure, which can prevent the transverse sliding structure from becoming loose or wobbling during vehicle operation, especially when encountering bumpy roads, thus reducing the stability of the seat and the safety of riding. In addition, external impacts (such as sudden braking) may also cause the seat to shift unexpectedly. Therefore, a transverse sliding structure for an automotive seat bracket and its rail connection structure are proposed.

[0006] To achieve the above objectives, this application provides a transverse sliding structure for an automotive seat bracket guide rail, including a base. The upper end of the base is provided with symmetrical sliding grooves, and sliding sleeves slide in the symmetrical sliding grooves respectively. Adjacent sliding sleeves are connected by a connecting rod. The upper end of the sliding sleeve is symmetrically provided with a slide rail, and a moving block is slidably provided in the slide rail. The moving block achieves transverse movement by sliding in the slide rail. An anti-slip component is installed at one end of the sliding sleeve, and the anti-slip component fixes the sliding sleeve.

[0007] Preferably, a lead screw is actively installed in the chute, the lead screw is driven by a motor, and the lead screw is threadedly connected to the moving block.

[0008] Preferably, a rack is connected between the two moving blocks, a rotating rod is rotatably mounted on the connecting rod, and gears are connected to both ends of the rotating rod. The gears mesh with the rack, and the rotating rod is driven by a motor.

[0009] Preferably, a limit rod is rotatably provided inside the slide rail, and the limit rod is slidably connected to the moving block.

[0010] Preferably, a spring is connected between the moving block and the side wall of the slide rail.

[0016] This utility model provides a transverse sliding structure for an automotive seat bracket guide rail and its guide rail connection structure, which, compared with the prior art:

[0017] 1. This utility model uses a movable block that moves laterally within a slide rail. Simultaneously, the meshing of gears and racks causes the rack to move the movable block automatically. This method provides precise position control and a large driving force. Furthermore, as the movable block slides, the tension and compression of springs on both sides help maintain the balance of the movable block and reduce the negative impact of external shocks on the system.

[0018] 2. This utility model uses a limiting plate that fits against one side of the positioning rod. When the moving block moves, the positioning rod contacts the positioning rod. Through the compression of the positioning rod, the positioning rod slides inside the positioning sleeve and compresses the second spring, further stabilizing the moving block. At the same time, the cylinder uses a fixing sleeve to fix the positioning rod and the positioning sleeve, thereby locking the slide rail and improving the stability of the seat after it moves.

[0030] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0031] Please refer to Figures 1 to 8 This utility model provides a transverse sliding structure for a car seat bracket guide rail and its guide rail connection structure, including a base 1. The upper end of the base 1 is provided with symmetrical sliding grooves 2. Sliding sleeves 4 slide in the symmetrical sliding grooves 2 respectively. Adjacent sliding sleeves 4 are connected by a connecting rod 8. The sliding of the sliding sleeves 4 in the sliding grooves 2 can satisfy the front and rear adjustment of the seat.

[0032] The slide 2 is equipped with a lead screw 3, which is driven by a motor. The lead screw 3 is threadedly connected to the moving block 11. After the motor drives the lead screw 3, the moving block 11 moves automatically, improving the accuracy of adjustment.

[0033] To enable the seat to move laterally, slide rails 15 are symmetrically arranged on the upper end of the slide sleeve 4. Moving blocks 11 are slidably arranged inside the slide rails 15. The moving blocks 11 move laterally by sliding inside the slide rails 15. A rack 12 is connected between the two moving blocks 11. A rotating rod 9 is rotatably arranged on the connecting rod 8. Gears 10 are connected to both ends of the rotating rod 9. The gears 10 mesh with the rack 12. The rotating rod 9 is driven by a motor. Therefore, when the rotating rod 9 rotates with the gears 10, the moving blocks 11 slide laterally inside the slide rails 15.

[0034] Furthermore, a limit rod 16 is rotatably installed inside the slide rail 15, and the limit rod 16 is slidably connected to the moving block 11 to improve the stability of the moving block 11.

[0035] An anti-slip component is installed at one end of the sliding sleeve 4, which fixes the sliding sleeve 4 in place.

[0036] Specifically, the anti-slip component includes a cylinder 5 installed at one end of the sliding sleeve 4, the piston end of the cylinder 5 being connected to the fixed sleeve 6, a positioning sleeve 19 fixedly installed on one side of the moving block 11, a positioning rod 20 slidably installed inside the positioning sleeve 19, a spring 21 connecting the positioning rod 20 and the positioning sleeve 19, and a limit plate 7 fixedly installed on one side of the slide rail 15, with one side of the limit plate 7 fitting against one side of the positioning rod 20. When the moving block 11 slides, the positioning rod 20 is restricted by the limit plate 7, causing the positioning sleeve 19 to compress the spring 21 and slide in cooperation with the positioning rod 20. After the moving block 11 slides to the appropriate position, the cylinder 5 pushes the fixed sleeve 6 to move, and the fixed sleeve 6 fixes the positioning sleeve 19 and the positioning rod 20 to one side of the slide rail 15, further improving the stability of the seat after lateral movement.

[0037] In addition, a limiting groove 18 is provided on one side of the slide rail 15, and one side of the moving block 11 is slidably connected to the limiting groove 18, which further improves the stability of the moving block 11.

[0038] On the other hand, the present invention also provides a guide rail connection structure, including a car seat bracket guide rail transverse sliding structure of any one of the above, including a mounting plate 13, a connecting plate 14 is provided at the upper end of the mounting plate 13, and the lower side of the mounting plate 13 is connected to the moving block 11. Therefore, after being connected to the car seat through the connecting plate 14, the movement of the moving block 11 can cause the seat to move.

[0039] In summary, the working principle of the car seat bracket guide rail transverse movement structure and its guide rail connection structure of this utility model embodiment is as follows: the connecting plate 14 is connected to the seat. When adjusting the seat, the screw 3 is rotated, causing the sliding sleeve 4 to slide in the sliding groove 2, thereby allowing the seat to move back and forth. The drive gear 10 is driven, and the gear 10 meshes with the rack 12, causing the rack 12 to move laterally with the slide rail 15. At the same time, the spring 17 is stretched and compressed to improve the stability of the moving block 11. When the moving block 11 moves, the positioning sleeve 19 and the positioning rod 20 slide together. Then, the cylinder 5 drives the fixing sleeve 6 to fix the positioning rod 20 and the positioning sleeve 19 to one side of the slide rail 15, thereby improving the overall stability.

[0040] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
