Technical Field
[0001] This utility model relates to the technical field of automotive seat slide rails, specifically to an anti-jamming rolling gap-eliminating component for automotive seat slide rails. Background Technology
[0002] Car seat rails are mechanical devices that allow drivers and passengers to adjust the fore-aft position and tilt angle of car seats, providing a more comfortable seating posture. In order to reduce the vibration of the rails, they are usually used in conjunction with bearings. As disclosed in CN221213598U, a gap-eliminating mechanism for automotive seat slide rails is provided. The upper slide rail includes a front fixed seat and a rear fixed seat, and a slide rail bracket welded between the front and rear fixed seats. Both sides of the front and rear fixed seats extend outwards with ear structures. Gap-eliminating blocks, made of plastic, are fitted onto the ear structures. The top surface of the gap-eliminating block is flush with the bottom surface of the lower slide rail anti-detachment hook, and its outer surface is flush with the inner walls of both sides of the lower slide rail. The top of the left and right side walls of the lower slide rail has an arc-shaped surface at its inward bend. The slide rail bracket has fixing structures on both sides, with at least two on each side. The two fixing structures are spaced apart. Each fixing structure has an outwardly extending, upwardly angled gap-eliminating wheel assembly. The gap-eliminating wheel assembly always abuts against the corresponding arc-shaped surface and can roll back and forth along the arc-shaped surface. This invention solves the problems of complex installation and poor performance of existing gap-eliminating mechanisms. However, existing technologies have problems such as the seats shaking when the car is moving, which can easily cause abnormal noises, and it is not convenient to eliminate gaps in both the lateral and vertical directions. For example, the comparative patents listed above have this problem. To address this issue, we propose an anti-jamming rolling gap-eliminating component for automotive seat slide rails. Summary of the Invention
[0003] The purpose of this utility model is to provide an anti-jamming rolling gap elimination component for automotive seat slide rails, so as to solve the problems mentioned in the background art, which are that when a car is bumpy during driving, the seat shakes and makes abnormal noises, and it is inconvenient to eliminate gaps in both the lateral and vertical directions in both directions.

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.
[0015] Please see Figures 1-6 .
[0016] To address the problems in existing technologies where seats shake and produce abnormal noises when a car is in motion, and where it is inconvenient to eliminate gaps in both the lateral and vertical directions, this solution provides an anti-jamming rolling gap-eliminating component for a car seat slide rail. The component comprises a lower rail 1 and a movable plate 2 positioned above the lower rail 1. Auxiliary plates 3 are fixedly connected to both ends of the movable plate 2, and a rubber support pad 4 is provided at the upper end of the auxiliary plate 3. The rubber support pad 4 is attached to the lower rail. Movable wheels 8 are provided at both the front and rear ends of the inner side of the lower rail 1, and a ring groove 9 for correction is provided in the middle of each movable wheel 8. The movable wheel 8 engages in a limiting groove 6 located inside the lower rail 1. A limiting strip 7 is fixedly connected to the middle of the limiting groove 6, and the limiting strip 7 engages in the ring groove 9. like Figure 1 , Figure 2 and Figure 3As shown, a movable plate 2 is provided above the lower rail 1. A mounting plate 14 is fixedly connected to the upper end of the movable plate 2. The mounting plate 14 is attached to the lower end of the upper rail and is positioned with bolts. Auxiliary plates 3 are fixedly connected to both the left and right ends of the movable plate 2. Rubber support pads 4 are provided at the upper ends of the auxiliary plates 3 and are tightly attached to the lower end of the upper rail. The rubber support pads 4 eliminate vertical gaps. Figure 4 , Figure 5 and Figure 6 As shown, a support block 13 is fixedly connected to the lower end of the movable plate 2. The support block 13 is fixed to the upper end of the connecting shaft 12. At the same time, both the front and rear ends of the connecting shaft 12 are inserted into the bearings 10, and there is an interference fit between the connecting shaft 12 and the bearings 10. The bearings 10 are locked and fixed in the movable wheel 8 by the fixing block 11. When the upper rail drives the connecting shaft 12 to move in the lower rail 1 through the mounting plate 14 and the movable plate 2, the movable wheel 8 rolls in the limiting groove 6, thereby limiting the movable wheel 8. The limiting strip 7 is locked in the annular groove 9, which further improves the stability of the movable wheel 8 during the movement and prevents deviation. Moreover, the ball bearing 5 at the lower end of the movable plate 2 rolls on the lower rail 1, which can support the movable plate 2 and further improve the stability of the movable plate 2 during the movement. This can eliminate the lateral gap, and the entire movement process is very smooth, preventing jamming.
