Description

Technical Field

[0001] The utility model relates to the technical field of automobile seats, in particular to a dustproof shielding structure for a long slide rail of an automobile seat. Background Art

[0002] The forward and backward movement adjustment of the car seat is usually achieved through the slide rail assembly under the seat. The driver and passengers can adjust the forward and backward position of the seat according to their own needs to obtain a more comfortable sitting posture. During the use of the slide rail assembly, dust often gathers on the guide rail surface, which sharply reduces the service life of the slide rail assembly. Therefore, dust strips are indispensable in the slide rail assembly. In the prior art, the dust strip on the slide rail is installed on the lower slide rail. The deformable area is generally made of elastic material and is arranged on both sides of the upper slide rail to cover the gap on the movement path of the upper slide rail. The dust strip overlapping with the upper slide rail will be stretched open by the upper slide rail, and the soft rubber of the non-overlapping part is in a horizontal natural state. Ideally, when the upper slide rail moves, the soft rubber in the overlapping area that is stretched open by the upper slide rail will gradually return to its original horizontal state due to its own elasticity, thereby covering the gap on the movement path of the upper slide rail. However, due to the characteristics of elastic materials, when the soft rubber is in a state of being stretched open by the upper slide rail for a long time, the soft rubber will undergo plastic deformation, and it cannot be restored to its original horizontal state even if the upper slide rail is removed. The soft rubber is always in an open state and cannot cover the gap on the movement path of the upper slide rail. Utility Model Content

DETAILED DESCRIPTION

[0022] In order to better understand the improvements made by the present invention relative to the prior art, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] like Figure 1-4 As shown, a long slide rail dust shielding structure for a car seat is mainly composed of a lower slide rail 1, an upper slide rail 5 and a fixed dust strip 2 arranged along the front-to-back direction. The upper slide rail 5 is shorter than the lower slide rail 1, and the upper slide rail 5 can be slid forward and backward on the lower slide rail 1.

[0024] like Figure 6 As shown, the lower slide rail 1 is a hollow slide rail with an opening in the middle extending in the front-rear direction, and the upper slide rail 5 is inserted into the opening through the connecting plate 502 at the bottom and is slidably connected to the lower slide rail 1. Figure 5 , 8 As shown, the connecting plate 502 is welded from two left and right pieces, and the lower end of at least one of the connecting plates 502 is bent outward for installing the pulley 8, thereby ensuring the smooth movement of the upper slide rail 5 and the limiting position between the upper and lower slide rails.

[0025] Two or more upper slide rails 5 can be provided on the same lower slide rail 1. The upper slide rails 5 are respectively connected to the corresponding rows of seats and can move independently, so that seats in different rows can be moved forward and backward independently on the same lower slide rail 1.

[0026] There are two fixed dustproof strips 2, which are fixedly arranged on the left and right sides of the upper sliding rail 5 respectively. Grooves 3 with narrow upper part and wide lower part are provided on both sides of the top surface of the lower sliding rail 1 along the front-back extension direction. Limiting ribs 4 are provided on the fixed dustproof strips 2 on both sides corresponding to the grooves 3 to realize the detachable connection between the lower sliding rail 1 and the fixed dustproof strip 2.

[0027] The two fixed dustproof strips 2 are connected by a zipper 204, and zipper heads 7 are fixedly provided at both ends of the upper slide rail 5, so that when the upper slide rail 5 moves forward and backward, the opening and closing of the zipper 204 is controlled to achieve the fixed dustproof strip 2 to keep the lower slide rail 1 and the upper slide rail 5 airtight.

[0028] When the upper slide rail 5 is adjusted to the left, the left zipper head 7 is responsible for separating the zipper 204, and the right zipper head 7 is responsible for merging the zipper 204. When the upper slide rail 5 is adjusted to the right, the left zipper head 7 is responsible for merging the zipper 204, and the right zipper head 7 is responsible for separating the zipper 204. At the same time, fixing frames 501 are provided at the front and rear ends of the upper slide rail 5. The fixing frames 501 are installed with the zipper heads 7 through the connecting brackets 6. The connecting brackets 6 adopt a pointed structure to ensure that the zipper 204 is separated smoothly, prevent the zipper 204 from being stuck, and ensure that the zipper 204 on the path that has been traveled can be separated and closed in real time.

[0029] like Figure 7 As shown, the fixed dust strip 2 is composed of a hard rubber body 201, an elastic soft rubber 202 and a zipper 204. The zipper 204 is arranged on the hard rubber body 201 through the elastic soft rubber 202. The elastic soft rubber 202 is provided with a convex point 205, such as Figure 8 As shown, when the zipper is in the separated state and is within the range of the upper slide rail, the protrusion 205 contacts the side of the upper slide rail 5, so that the zipper 204 is away from the upper slide rail, and the zipper 204 is away from the upper slide rail 5, so as to prevent the zipper 204 from being damaged due to contact friction. At the same time, a wear-resistant lubricating coating 203 is brushed on the bottom of the elastic soft rubber 202, which can further reduce the friction between the side of the upper slide rail and the soft rubber, and reduce wear. At the same time, the wear-resistant lubricating coating has very good sliding performance, which can effectively reduce the friction noise between the soft rubber and the metal.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
