[0033] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention
[0034] Reference will be made below to Figures 1 - 7 describe the middle guide rail 10 of the sliding door, the sliding door frame 100 and the vehicle according to the embodiments of the present invention
[0035] The middle guide rail 10 of the sliding door according to the embodiments of the present invention includes a guide rail body 1 and a sealing member 2
[0036] The guide rail body 1 has a preset direction (for example, Figure 1 and Figure 5A first channel 11 extending in the left - right direction (as shown in the figure) is provided in the guide rail body 1. The guide rail body 1 can form a second channel 3 with the outer side panel 20 and the corner window 30. The blocking member 2 is arranged at one end of the guide rail body 1 (for example, Figure 5 the right end shown in the figure), and the blocking member 2 blocks the first channel 11 and / or the second channel 3. It can be understood that the blocking member 2 blocks the first channel 11; or the blocking member 2 blocks the second channel 3, or the blocking member 2 blocks both the first channel 11 and the second channel 3.
[0037] In the guide rail 10 of the sliding door according to the embodiment of the present utility model, by providing the blocking member 2 to block the first channel 11 of the guide rail body 1 and / or the second channel 3 formed by the guide rail body 1, the outer side panel 20 and the corner window 30, it is possible to avoid the problem of wind noise caused by high - speed air flow entering the first channel 11 and / or the second channel 3 when the vehicle is running at high speed. At the same time, by blocking the first channel 11 and / or the second channel 3 with the blocking member 2, the air tightness of the vehicle is improved, and further, the problem of indoor humidity and mildew caused by high - humidity gas or rainwater entering the carriage is avoided.
[0038] Therefore, the guide rail 10 of the sliding door according to the embodiment of the present utility model has the advantages of low wind noise and good sealing performance.
[0039] Generally, both the first channel 11 and the second channel 3 extend along a preset direction. The outer side panel 20 is usually a sheet metal part.
[0040] As Figure 3 shown, Figure 6 and Figure 7 shown, the blocking member 2 includes a plug cover 21 and a flexible layer 22 provided on the plug cover 21. The plug cover 21 is arranged at one end of the first channel 11 of the guide rail body 1, and the flexible layer 22 blocks the second channel 3. Specifically, the flexible layer 22 can be in contact with at least one of the outer side panel 20 and the corner window 30.
[0041] In the guide rail 10 of the sliding door according to the embodiment of the present utility model, by dividing the blocking member 2 into a plug cover 21 and a flexible layer 22 provided on the plug cover 21, the plug cover 21 can prevent air flow from entering the first channel 11, reducing the wind noise inside the guide rail body 1. In addition, by blocking the second channel 3 with the flexible layer 22, it helps to improve the applicability of the blocking member 2. At the same time, because the flexible layer 22 can adapt to an irregular mating surface and can deform adaptively according to the outer contour of the second channel 3 formed between the outer side panel 20, the corner window 30 and the guide rail body 1. Moreover, during the vehicle assembly process, the flexible layer 22 can be filled in the second channel 3 to block the second channel 3, which not only has low assembly difficulty and good matching, but also helps to further reduce the problem of wind noise inside the carriage.
[0042] Furthermore, both the outer side panel 20 and the corner window 30 can be in contact with the flexible layer 22.
[0043] Optionally, the flexible layer 22 can be one of foam, rubber, and silica gel. Using foam as the flexible layer 22 has the advantages of low cost, low density, and good weather resistance.
[0044] As Figure 3 and Figure 4 shown, the plug cover 21 is snap-connected to one end of the guide rail body 1 (for example, Figure 1 the right end shown in ). In the sliding door guide rail 10 of the embodiment of the present invention, the plug cover 21 and the guide rail body 1 are connected by snap connection. This connection method of the structure has the advantages of good connection stability and high installation convenience.
[0045] As Figure 3 and Figure 7 shown, the wall surface of one end of the guide rail body 1 that cooperates with the plugging member 2 has a snap hole (not shown). The plug cover 21 includes a plate body portion 211, a plugging portion 212, and a snap portion 213. The plate body portion 211 abuts against one end of the guide rail body 1. The plugging portion 212 is inserted into the first channel 11. The snap portion 213 is disposed on the outer peripheral surface of the plugging portion 212, and the snap portion 213 is snapped into the snap hole.
[0046] In the sliding door guide rail 10 of the embodiment of the present invention, by dividing the plug cover 21 into a plate body portion 211, a plugging portion 212, and a snap portion 213, and the plate body portion 211 abuts against one end of the guide rail body 1, the plate body portion 211 can bear the acting force along the preset direction, and the acting force of the air flow on the plate body portion 211 can be enhanced. And the plugging portion 212 is inserted into the first channel 11. The snap portion 213 is disposed on the outer peripheral surface of the plugging portion 212, and the snap portion 213 is snapped into the snap hole. Thus, the installation convenience of the plug cover 21 is improved.
[0047] Optionally, the outer peripheral contour of the plate body portion 211 is substantially the same as the outer peripheral contour of the guide rail body 1, and the shape of the plugging portion 212 is substantially the same as the first channel 11.
[0048] The plug cover 21 further includes a reinforcing portion (not shown), and the reinforcing portion is disposed on the plate body portion 211. Optionally, the reinforcing portion can be a reinforcing rib plate formed on the plate body portion 211.
[0049] In the sliding door guide rail 10 of the embodiment of the present invention, by providing a reinforcing portion on the plate body portion 211, the structural strength of the plate body portion 211 can be improved, and the force-bearing capacity of the plug cover 21 can be enhanced. Furthermore, it can withstand a large air flow impact and is not easily deformed or broken. Thus, the sliding door guide rail 10 of the embodiment of the present invention has the advantage of high structural strength.
[0050] The middle guide rail 10 of the sliding door in the embodiment of the present utility model further includes an adhesive layer (not shown), and the adhesive layer is disposed between the flexible layer 22 and the plug cover 21. In other words, the flexible layer 22 and the plug cover 21 are connected through the adhesive layer.
[0051] For the middle guide rail 10 of the sliding door in the embodiment of the present utility model, connecting the flexible layer 22 and the plug cover 21 through the adhesive layer can avoid the problem that the flexible layer 22 falls off from the plug cover 21. Therefore, the middle guide rail 10 of the sliding door in the embodiment of the present utility model has the advantages of high installation convenience and good stability.
[0052] As Figure 3 and Figure 7 shown, the flexible layer 22 includes a main body portion 221 and an edge portion 222 extending outward along the outer periphery of the main body portion 221. The main body portion 221 is attached to the plug cover 21, and the edge portion 222 is used to abut against the side outer panel 20 and / or the corner window 30. In other words, along the preset direction, the projection of the plug cover 21 is located within the projection of the edge portion 222.
[0053] For the middle guide rail 10 of the sliding door in the embodiment of the present utility model, by dividing the flexible layer 22 into the main body portion 221 and the edge portion 222 extending outward along the outer periphery of the main body portion 221, and the edge portion 222 is used to abut against the side outer panel 20 and / or the corner window 30, the edge portion 222 can completely block the channel opening of the second channel 3. After assembly, there is no gap with the side outer panel 20 and the corner window 30, and the sealing performance of this structure is good. Thus, the middle guide rail 10 of the sliding door in the embodiment of the present utility model has the advantage of reducing wind noise.
[0054] Specifically, the shape and size of the main body portion 221 are substantially the same as those of the plate body portion 211. The cross-sectional shape of the edge portion 222 is the same as the cross-sectional shape of the second channel. The edge portion 222 surrounds the outer periphery of the plate body portion 211 so that when the edge portion 222 is squeezed, the shape of the edge portion 222 can be roughly supported.
[0055] The sliding door frame 100 in the embodiment of the present utility model includes a side outer panel 20, a corner window 30, and the middle guide rail 10 according to any one of the above. The blocking member 2 is disposed at one end of the guide rail body 1, and the blocking member 2 blocks the first channel 11 and / or the second channel 3.
[0056] Therefore, the sliding door frame 100 in the embodiment of the present utility model has the advantages of low wind noise and good sealing performance.
[0057] As Figure 3 and Figure 7As shown, the plugging member 2 includes a plug cover 21 and a flexible layer 22 provided on the plug cover 21. The flexible layer 22 includes a main body portion 221 and an edge portion 222 extending outward along the outer periphery of the main body portion 221. The main body portion 221 is attached to the plug cover 21. The maximum vertical distance between the outer wall of the guide rail body 1 and the inner wall of the side outer panel 20 is a, the maximum vertical distance between the guide rail body 1 and the corner window 30 is b, and the width of the edge portion 222 is c, where c ≥ 2a, and / or c ≥ 2b.
[0058] It can be understood that after being installed in place, the actual compression amount of the edge portion 222 is greater than 50%.
[0059] In the sliding door frame 100 of the embodiment of the present utility model, by setting the maximum vertical distance between the guide rail body 1 and the corner window 30 as b, the width of the edge portion 222 as c, and making the width c of the edge portion 222 satisfy c ≥ 2a, that is, the actual compression amount of the flexible layer 22 (for example, foam) is greater than 50%, because only by ensuring a certain compression amount can the gap between the guide rail body 1 and the corner window 30 be filled by the flexible layer 22. Thus, the sliding door frame 100 improves the sealing effect between the guide rail body 1 and the corner window 30.
[0060] Similarly, when c ≥ 2b for the width of the edge portion 222, the sealing between the guide rail body 1 and the corner window 30 is ensured. Thus, the sliding door frame 100 has the advantage of good sealing effect.
[0061] The vehicle of the embodiment of the present utility model includes the sliding door frame 100 according to any one of the above.
[0062] Therefore, the vehicle of the embodiment of the present utility model has the advantages of low wind noise and good sealing performance.
