Description

Technical Field

[0001] The utility model relates to the technical field of automobile sealing, and in particular to a sealing structure of a door slide rail. In addition, the utility model also relates to a vehicle. Background Art

[0002] In MPV (multi-purpose vehicles) models, sliding doors are usually used. The doors slide through middle slide rails (hereinafter referred to as door slide rails) installed on the side panel to achieve opening and closing of the doors.

[0003] A side panel is generally provided on the side panel metal at the bottom side of the door rail, and a sealing strip is provided between the side panel and the door rail to ensure the sealing between the door rail and the side panel. The existing sealing strip structure overlaps the end of the door rail and the edge of the side panel through two overlapping lips at the top. There is usually a gap between the overlapping lip and the door rail, and between the overlapping lip and the side panel. Over time, the overlapping lip is prone to curling, which further increases the gap and affects the sealing performance of the sealing strip. When the curling of the overlapping lip is squeezed into the gap, for example, rolled into the inside of the side panel decoration, it seriously affects the appearance and neatness of the joint between the side panel and the door rail. Utility Model Content

[0004] In view of this, the utility model aims to provide a sealing structure for a vehicle door slide rail, so as to improve the sealing performance between the vehicle door slide rail and the side panel decorative panel.

[0005] In order to achieve the above object, the technical solution of the utility model is implemented as follows:

[0006] A sealing structure for a vehicle door slide rail,

[0007] It includes a sealing strip arranged on the side panel; the sealing strip has a main body with a rectangular cross-section, and a first lip and a second lip are respectively provided on both sides of the top of the main body; the main body is clamped between the side panel decorative panel and the door slide rail, the first lip covers the side panel decorative panel, and the second lip covers the door slide rail.

[0008] Furthermore, the sealing strip also includes a fixing portion, which is extended from the bottom of one side of the main body facing the door slide rail in the direction of the door slide rail, and is clamped between the door slide rail and the side panel metal.

[0009] Furthermore, a gasket is provided between the door slide rail and the fixing portion.

[0010] Furthermore, a bubble tube cavity is formed in the main body.

[0011] Furthermore, the main body has a first side wall located between the bubble tube cavity and the side surrounding decorative plate; the wall thickness of the first side wall is gradually thinned in a direction away from the side surrounding sheet metal.

[0012] Furthermore, a bending portion is formed at one end of the side decorative plate abutting against the main body, and a first interference dimension is set between the bending portion and the main body.

[0018] In addition, a fixing portion is provided at the bottom of the sealing strip, which is pressed onto the side panel sheet metal by the door slide rail, so that the sealing strip can be reliably fixed between the door slide rail and the side panel sheet metal. Not only is the installation method simple, but the position of the sealing strip between the side panel sheet metal, the door slide rail and the side panel decorative panel is more stable.

[0019] In addition, a hollow bubble tube cavity is provided inside the main body, which can effectively improve the extrusion deformation performance of the main body, so that the sealing strip and the side panel, as well as the sealing strip and the door rail can be more closely fitted. In addition to the bubble tube cavity, an anti-pull line can also be provided inside the main body. The anti-pull line can be made of anti-stretching fiber to prevent the sealing strip from being stretched and changing in size during extrusion molding.

[0033] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0034] Embodiment 1

[0035] This embodiment relates to a sealing structure for a vehicle door slide rail, which can improve the sealing performance between the vehicle door slide rail 2 and the side panel decorative panel 10; an exemplary structure thereof is as follows: Figure 1 , Figure 2 and Figure 3 shown.

[0036] In general, the sealing structure of the door slide rail includes a sealing strip 3 provided on the side panel 1; the sealing strip 3 has a main body 30 with a rectangular cross section, and a first lip 301 and a second lip 306 are provided on both sides of the top of the main body 30. The main body 30 is clamped between the side panel trim 10 and the door slide rail 2, the first lip 301 covers the side panel trim 10, and the second lip 306 covers the door slide rail 2.

[0037] Specifically, the sealing strip 3 of the present embodiment further includes a fixing portion 31, which is extended from the bottom of the main body 30 facing the door slide rail 2 in the direction of the door slide rail 2, and is clamped between the door slide rail 2 and the side panel 1. The fixing portion 31 is arranged at the bottom of the sealing strip 3, and the fixing portion 31 is pressed against the side panel 1 by the door slide rail 2, so that the sealing strip 3 can be reliably fixed between the door slide rail 2 and the side panel 1. Not only is the installation method simple, but the position of the sealing strip 3 between the side panel 1, the door slide rail 2 and the side panel decorative panel 10 is more stable.

[0038] Based on the setting of the fixing part 31, it is preferred to set a gasket 21 between the door slide rail 2 and the fixing part 31. By setting the gasket 21, it can not only meet the different assembly gap requirements between the door slide rail 2 and the side panel 1, but also more effectively improve the pressing force of the door slide rail 2 on the fixing part 31. Of course, the gasket 21 can be a conventional soft pad, or a rubber pad with colloid coated on both sides, so as to achieve the bonding between the door slide rail 2 and the fixing part 31, and improve the installation convenience and reliability of the sealing strip 3.

[0039] like Figure 2 and Figure 3 As shown, a bubble tube cavity 300 is preferably formed in the main body 30. The size of the bubble tube cavity 300 can be reasonably set according to the overall size of the sealing strip 3; in this embodiment, the width W of the bubble tube cavity 300 is 2.11 mm, and the height H is 2.36 mm. The hollow bubble tube cavity 300 is arranged inside the main body 30, which can effectively improve the extrusion deformation performance of the main body 30, so that the sealing strip 3 and the side decorative panel 10, and the sealing strip 3 and the door slide rail 2 can be more closely fitted. In addition to the bubble tube cavity 300, an anti-pull line 302 can also be arranged in the main body 30. The anti-pull line 302 is preferably made of fiber filaments that are not easily deformed and stretched when stretched. The anti-pull line 302 is embedded in the main body 30 to prevent the sealing strip 3 from changing in size due to being stretched during extrusion molding.

[0040] Based on the arrangement of the bubble tube cavity 300, a first side wall 304 and a second side wall 305 of the main body 30 are formed on the left and right sides of the bubble tube cavity 300, wherein the side panel 10 abuts against the first side wall 304, and the end 20 of the door slide 2 abuts against the second side wall 305. The wall thickness D of the first side wall 304 is preferably set between 0.6 mm and 1.2 mm; in this embodiment, the wall thickness D is about 0.8 mm, so that the main body 30 can be deformed quickly when squeezed, forming a smaller reaction force, and the first lip edge 301 and the second lip edge 306 at the top thereof will change and close together accordingly, forming a zero-fit lap seal between the side panel 10 and the door slide 2.

[0041] In addition, in the present embodiment, the wall thickness D of the first side wall 304 located between the bubble tube cavity 300 and the side surrounding decorative panel 10 is gradually thinned in the direction away from the side surrounding sheet metal 1; this will form an obvious concave portion between the first side wall 304 and the first lip edge 301, and when the side surrounding decorative panel 10 abuts against and squeezes the first side wall 304, the first lip edge 301 is more likely to close to the surface of the side surrounding decorative panel 10, thereby improving the close fit between the first lip edge 301 and the side surrounding decorative panel 10.

[0042] For the wall thickness of the bubble tube cavity 300 at other locations on the main body 30, such as the portion where the second side wall 305 abuts against the end 20 of the door slide rail 2, and the portion where the bottom corner 303 abuts against the side panel sheet metal 1, it is preferred to set the wall thickness to be above 1.8 mm. This helps to improve the overall supporting performance of the main body 30 and prevent the main body 30 from being excessively deformed by being squeezed and clamped by the side panel decorative panel 10 and the door slide rail 2, resulting in problems such as the side panel decorative panel 10 not being installed to the bottom and the fit being loose.

[0043] In addition, a bending portion 100 is formed at one end of the side panel decorative plate 10 abutting against the main body 30, and a first interference dimension B1 is set between the bending portion 100 and the main body 30. By setting the bending portion 100 at the end of the side panel decorative plate 10, a round head-shaped abutting surface is formed on the side of the bending portion 100 facing the main body 30, and the abutting surface abuts against the main body 30. In the case of interference fit between the bending portion 100 and the main body 30, the stress state between the bending portion 100 and the main body 30 can be improved, and the first lip edge 301 side of the main body 30 has a better deformation effect, and the close fit between the first lip edge 301 and the side panel decorative plate 10 is improved. The above-mentioned first interference dimension B1 is preferably set between 0.3mm and 0.8mm.

[0044] At the same time, the bottom corner 303 of the main body 30 of this embodiment facing the side panel 10 is convexly arranged toward the side panel sheet metal 1, and a second interference dimension B2 is arranged between the bottom corner 303 and the surface of the side panel sheet metal 1, and the second interference dimension B2 is between 0.2mm and 0.6mm. In addition, due to the existence of the first interference dimension B1, it can adapt to the small range fluctuation of the size of the side panel sheet metal 1, and the side panel sheet metal 1 can play a stable supporting role in the deformation process of the sealing strip 3, which can prevent the lower part of the main body 30 from being severely deformed, and play a reliable supporting role for the sealing cooperation between the side panel 10 and the sealing strip 3, and between the door slide rail 2 and the sealing strip 3.

[0045] Based on the above-mentioned settings, a certain gap can be reserved between the first lip edge 301 of the sealing strip 3 in a natural state (when the main body 30 is not squeezed and clamped by the side panel decorative panel 10 and the door slide rail 2) and the surface of the side panel decorative panel 10, and the gap size T of the gap is preferably set between 0.2mm and 0.5mm.

[0046] By setting a gap size T of 0.2mm to 0.5mm between the first lip 301 and the side panel 10, a good balance is formed with the first interference size B1 and the second interference size B2, which will make the product in the best state of squeezed interference after installation (the overall interference amount is about 0.3mm). In the specific installation process, the main body 30 is squeezed and clamped by the side panel 10 and the door slide 2, and the bent portion 100 of the side panel 10 will be pressed against the first side wall 304, and the first side wall 304 will be deformed toward the inside of the bubble tube cavity 300, thereby driving the first lip 301 to approach the surface of the side panel 10, so that the gap between the first lip 301 and the surface of the side panel 10 disappears, and finally the first lip 301 is tightly attached to the side panel 10. It can be seen that the above setting can not only improve the aesthetics of the connection between the door slide 2 and the side panel 10, but also improve the curling problem of the first lip 301.

[0047] It should be pointed out that the above-mentioned interference dimensions, gap dimensions, etc. are all matching dimensions between the sealing strip 3 and the surrounding parts when it is in a natural state. Once the sealing strip 3 is installed in place, the parts are squeezed and matched with each other, the gaps will disappear, and the parts with interference dimensions will be squeezed and abutted together. Figure 1 , Figure 2 and Figure 3 The sealing strips 3 shown in the figures are all in a natural state, so as to reflect the gap size and interference fit size between the sealing strip 3 and the surrounding components.

[0048] To sum up, in the sealing structure of the door slide rail of the present embodiment, the sealing strip 3 adopts a main body 30 with a rectangular cross-section. When the door slide rail 2 and the side panel decorative panel 10 squeeze and clamp the main body 30 from both sides of the main body 30, due to the force deformation of the main body 30, the lips on both sides of the top will be close to the surface of the door slide rail 2 or the side panel decorative panel 10 to achieve a tight zero-fit state. When various parts of the sealing strip 3 are subjected to force deformation, various parts of the sealing strip 3 are tightly fitted with the surfaces of the door slide rail 2 and the side panel decorative panel 10, which can greatly enhance the sealing performance and effectively prevent the lip from curling or being rolled into the gap on one side of the side panel decorative panel 10, thereby improving the sealing performance between the door slide rail 2 and the side panel decorative panel 10.

[0049] Embodiment 2

[0050] The present embodiment relates to a vehicle, wherein a door slide rail 2 is provided on a side panel 1 of the vehicle, and the door slide rail 2 adopts the sealing structure of the door slide rail provided in the first embodiment.

[0051] The sealing strip 3 of the utility model is used between the door slide rail 2 and the side panel 10. When the side panel 10 is installed, the sealing strip 3 can be compressed and deformed to achieve a zero fit state. The reserved gap between the first lip 301 and the side panel 10 will change with the deformation of the main body 30 and fit tightly on the side panel 10, solving the problem of the lip being prone to curling. The interference and gap between the sealing strip 3 and the surrounding components cooperate with each other to obtain a good balance and sealing effect. The reasonable coordination of the gap amount and the interference amount effectively avoids the problem of the lip being prone to curling or being rolled into the side panel 10.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
