Description

Technical Field

[0001] This utility model relates to the field of automotive seats, and in particular to a long-distance slide rail mechanism for automotive seat systems. Background Technology

[0002] During the sliding process of a car seat, a long sliding rail mechanism is required, such as... Figure 6 As shown, the existing long slide rail mechanism has a gap in the middle of the dustproof soft rubber strip that extends from one end to the other. This results in poor dustproof and waterproof performance, high noise, and the traditional slide rail is exposed on the vehicle floor. Dust, debris, or liquid can easily enter the slide rail, hindering sliding and even causing corrosion. Frequent cleaning and maintenance are required. The extended structure of the long slide rail may create hard-to-reach cleaning blind spots, increasing the difficulty of maintenance. During the back-and-forth movement of the upper guide rail, the dustproof soft rubber strip will be stretched open. The upper guide rail will repeatedly squeeze and stretch the rubber strip during displacement, which will accelerate its aging. Utility Model Content

[0003] In view of the problems existing in the prior art, the present invention aims to provide a long slide rail mechanism with full-travel shielding for automobile seats, so as to solve the problem of gaps in the sliding process of current long slide rail mechanisms.

[0004] To achieve the above objectives, this utility model proposes a long slide rail mechanism for full-travel coverage of a car seat, including a lower slide rail, a dustproof rubber strip, and an upper slide rail. The dustproof rubber strip is installed in the gap at the top of the lower slide rail. It also includes a pressure roller and a tension roller. The upper slide rail includes an upper support bracket and a lower support bracket fixed together. When the upper slide rail moves back and forth through the rolling roller, the dustproof rubber strip inside the upper support bracket partially detaches from the lower slide rail. The two ends of the detached section are pressed by the pressure roller installed in the upper support bracket, and the middle part of the detached section is tensioned by the tension roller installed in the upper support bracket.

[0005] As a preferred embodiment of the above solution, the upper rail support is formed by two sheet metal parts on the left and right sides fastening together to form a cover shape, and the upper rail support and the lower rail support are connected by bolts.

[0006] Further preferably, brushes are installed on both the front and rear outer sides of the upper rail bracket. When the upper rail bracket moves back and forth, the brushes are used to remove dust from the dustproof rubber strip. During the movement of the upper slide rail, the brushes clean dust and debris, preventing them from being carried into the lower slide rail and damaging the slide rail mechanism.

[0007] More preferably, the left and right sides of the top gap of the lower slide rail are respectively provided with ribs, which, together with the grooves provided at the bottom of the dustproof strip, form an anti-detachment structure. The front and rear ends of the dustproof strip are fixedly installed on the lower slide rail. When the upper slide rail moves back and forth through the rolling wheel, the dustproof strip that is covered in the upper rail bracket and is located near the front end can be pulled out from the lower slide rail. The dustproof strip that is covered in the upper rail bracket and is located near the rear end can be pressed into the gap of the lower slide rail by the pressing wheel at the rear.

[0008] More preferably, the dustproof strip has a reinforcing part in the middle that falls into the gap of the sliding rail, and a through weight-reducing groove is provided directly above the reinforcing part.

[0009] More preferably, there are two tensioning wheels, which are spaced apart from each other and the distance between them is less than the distance between the two pressing wheels. The two tensioning wheels and the two pressing wheels are arranged in an isosceles trapezoidal shape.

[0010] A further preferred embodiment is that the tensioning wheel is provided with discs at both its left and right ends, and the dustproof strip is located between the two discs to limit the left and right movement of the dustproof strip.

[0011] More preferably, the left and right sheet metal parts of the upper rail bracket are both equipped with a top flange, a front flange, and a rear flange, and the left and right sheet metal parts are welded together by flange welding.

[0012] The beneficial effects of this utility model are:

[0013] (1) The dustproof rubber strip is installed in the gap at the top of the lower slide rail. By designing the upper slide rail as an upper support and a lower support, and combining the pressure wheel and tension wheel to install the dustproof rubber strip, the upper slide rail will not have gaps during the sliding process, effectively preventing foreign objects from entering the lower slide rail and affecting the sliding of the lower slide rail. It also effectively blocks the noise of the slide rail during operation and improves the riding experience.

[0014] (2) When the dustproof rubber strip is partially dislodged from the lower rail, the pressure wheel and tension wheel exert force on the dustproof rubber strip respectively, which can tension the dustproof rubber strip while ensuring that the dustproof rubber strip is straightened, and avoid repeatedly opening and closing the dustproof rubber strip, thus shortening the life of the dustproof rubber strip.

[0015] In summary, this utility model has a novel concept and ingenious design, effectively blocks noise, achieves efficient dust prevention, increases the lifespan of the dustproof strip, and is easy to implement. Attached Figure Description

[0022] like Figure 1 As shown in Figure 5, a long slide rail mechanism for full-travel concealment of a car seat mainly consists of a lower slide rail 1, a dustproof rubber strip 2, an upper slide rail, a pressure roller 3, a tension roller 4, a rolling roller 5, a brush 6, a rib 9, a groove 10, and a reinforcing part 11.

[0023] The dustproof rubber strip 2 is installed in the gap at the top of the lower slide rail 1. The upper slide rail includes an upper rail bracket 7 and an upper rail lower bracket 8 fixed together. The pressure roller 3 and tension roller 4 are installed inside the upper rail bracket 7. There are two pressure rollers 3 and two tension rollers 4, or one tension roller 4 may be used. Part of the dustproof rubber strip 2 is located outside the upper rail bracket 7 and tightly fits into the gap at the top of the lower slide rail 1; another part is inserted inside the upper rail bracket 7, serving as a detachable section.

[0024] When the upper slide rail moves back and forth through the rolling wheel 5, the dustproof rubber strip 2 inside the upper support 7 of the upper rail partially detaches from the lower slide rail 1, and the two ends of the detached section are pressed by the pressure wheel 3, while the middle part of the detached section is tensioned by the tension wheel 4.

[0025] The front and rear ends of the dustproof strip 2 are fixedly installed on the lower slide rail 1. The left and right sides of the top gap of the lower slide rail 1 are respectively provided with ribs 9, which together with the grooves 10 provided at the bottom of the dustproof strip 2 form an anti-detachment structure. The middle part of the dustproof strip 2 is provided with a reinforcing part 11 that falls into the gap of the lower slide rail 1, and a through weight reduction groove is provided directly above the reinforcing part 11.

[0026] The upper rail support 7 is made of two sheet metal parts that are fastened together to form a cover shape. The upper rail support and the lower rail support are connected by bolts.

[0027] The left and right sheet metal parts of the upper rail bracket 7 are equipped with top flange, front flange, and rear flange. The left and right sheet metal parts are fastened together and welded by flange welding.

[0028] There are two tensioning wheels 4 inside the upper rail bracket 7, which are spaced apart and the distance between them is less than the distance between the two pressing wheels 3. The two tensioning wheels 4 and the two pressing wheels 3 are arranged in an isosceles trapezoidal shape.

[0029] Both ends of the tension wheel 4 are equipped with discs, and the dustproof rubber strip 2 is located between the two discs to limit the left and right movement of the dustproof rubber strip 2.

[0030] When the upper slide rail moves back and forth via the rolling wheel 5, it can pull the dustproof rubber strip 2, which is encased in the upper support 7 and located near the front end, out of the lower slide rail 1. The rear clamping wheel 3 then presses the dustproof rubber strip 2, which is encased in the upper support 7 and located near the rear end, into the gap of the lower slide rail 1. Preferably, the rib 9 is round-headed.

[0031] Brushes 6 are installed on the front and rear outer sides of the upper rail bracket 7. When the upper rail bracket 7 moves back and forth, the brushes 6 are used to remove dust from the dustproof rubber strip 2.
