And the inclined plate is arranged, so that the foreign matter falling on the corrugated isolation cloth can be discharged downwards, the foreign matter is prevented from being accumulated on the mother rail, and normal sliding of the sliding rail is effectively prevented from being influenced.

Description

Technical Field

[0001] The utility model relates to the technical field of vehicle seat slide rail accessories, in particular to a slide rail with an anti-foreign matter group structure. Background Art

[0002] The slide rails that adjust the longitudinal movement of vehicle seats typically consist of a mother rail fixed to the vehicle floor and a male rail that slides on the mother rail. The vehicle seat is fixed to the male rail and is driven by the male rail for adjustment. Currently, the common structures that drive the male rail on the market often use a gearbox as the sliding component. However, most structures using a gearbox have the mother rail's groove facing upward, with the gearbox placed inside the groove. In such a structure, foreign matter can easily enter the mother rail, affecting the smooth operation of the slide rail, generating abnormal noise, and even causing safety issues. Utility Model Content

[0004] The two wheels are connected to each other through the T-shaped slide and the T-shaped slide is connected to the T-shaped slide. The two wheels are connected to each other through the T-shaped slide and the T-shaped slide is connected to the T-shaped slide. The two wheels are connected to each other through the T-shaped slide.

[0005] Furthermore, the two sliding blocks located at the endmost side are fixedly connected to the inner side wall of the sliding cavity.

[0006] Furthermore, the cross section of the corrugated isolation cloth is arranged in a herringbone shape when viewed from the front, and the corrugated isolation cloth is made of polyester fiber.

[0007] Furthermore, an inclined plate is fixedly connected to one side of the shaking plate away from the top center of the mother rail, and the downward angle between the inclined plate and the shaking plate is set to be an acute angle.

[0008] Furthermore, a first groove is provided on the inner wall of the T-shaped slide, and a cam is provided in the inner cavity of the first groove, a rotating rod is fixedly connected to the bottom of the cam, a second groove is provided on the inner wall of the mother rail, and a through hole is provided on the top of the second groove which is connected to the inner cavity of the first groove, the bottom end of the rotating rod passes through the through hole and is rotatably connected to the bottom of the inner cavity of the second groove, a gear is fixed on the outer wall of the rotating rod, and a rack is engaged with the outer side of the gear, a connecting rod is fixedly connected to the side of the rack away from the gear, and the other end of the connecting rod is fixedly connected to the male rail.

[0009] Compared with the prior art, the beneficial effects of the present invention are:

[0010] 1. Through the arrangement of the corrugated isolation cloth, the skeleton rod, the sliding block, the sliding cavity, the shaking plate and the inclined plate, when the male rail slides on the female rail, the corrugated isolation cloth on both sides of it can be driven to contract and extend, thereby realizing the function of blocking foreign objects on the female rail. Moreover, the arrangement of the inclined plate can discharge foreign objects that fall on the corrugated isolation cloth downward, preventing foreign objects from accumulating on the female rail, thereby effectively preventing the normal sliding of the slide rail;

[0011] 2. Through the arrangement of the connecting rod, rack, gear, rotating rod, cam, T-shaped slide, T-shaped slide groove and return spring, the public rail can drive the rack to move horizontally during the sliding process, thereby driving the gear to rotate. The gear rotation drives the rotating rod to rotate, and drives the cam to rotate. When the farthest point of the cam contacts the T-shaped slide, it can push the T-shaped slide to overcome the resistance of the return spring and slide horizontally. After the cam moves away from the T-shaped slide, the return spring resets the T-shaped slide, thereby driving the shaking plate to shake back and forth, and then quickly shake off foreign matter on the corrugated isolation cloth, further playing the role of blocking foreign matter from the parent rail.
