Description

Technical Field

[0001] The utility model belongs to the technical field of vehicles, and in particular relates to a sealing structure, a sliding door and a vehicle. Background Art

[0002] At present, MPV (Multi-Purpose Vehicle) and other vehicle models all use self-priming sliding doors to increase the convenience of getting on and off the vehicle. How to improve the performance of sliding doors has gradually become a key research topic for major automobile companies.

[0003] The middle rail on the sliding door currently on the market is overlapped with the edge of the side panel decoration by an attached rubber strip (Thermoplastic Vulcanizate Rubber Strip, TPV). The rubber strip is roughly I-shaped, and the edge of the side panel decoration close to the middle rail is bent to form a smooth hook-shaped edge. A mounting groove is formed on the side of the rubber strip facing the middle rail, and the middle rail is installed in the mounting groove. A clamping groove is formed on the extended end of the rubber strip close to the side panel decoration. When the middle rail and the side panel decoration are assembled, the hook-shaped edge of the side panel decoration can be clamped into the clamping groove. However, due to the problem of installation tolerance, there may be a gap between the side panel decoration and the rubber strip, and it cannot be tightly clamped into the clamping groove, which affects the connection between the side panel decoration and the middle rail. The sealing between the side panel decoration and the rubber strip may be damaged, causing water leakage in the vehicle body; the extrusion pressure between the side panel decoration and the rubber strip may be too large, which not only causes the rubber strip to be squeezed and deformed abnormally, but also causes abnormal noise due to the relative movement between the side panel decoration and the rubber strip during the use of the vehicle; the side panel decoration may also be misaligned with the slot, causing the extended end of the rubber strip close to the side panel decoration to be squeezed into the slot, and the abnormally deformed rubber strip needs to be smoothed. The smoothing process may also cause the rubber strip to deform into other shapes and reduce the service life of the rubber strip. Utility Model Content

The hook 931 is close to the lower extension end of the middle slide rail body 92. A sealing structure 100 is provided between the side wall decoration 93 and the middle slide rail body 92.

[0030] See also Figure 2 The embodiment of the utility model further provides a sealing structure 100, which is connected between the first structural member and the second structural member, and is used to achieve sealing between the first structural member and the second structural member. In the illustrated embodiment, the sliding door 90 may include the sealing structure 100, the first structural member and the second structural member may both be structural members on the sliding door 90, the first structural member may include a middle sliding rail body 92, the second structural member may include a side wall decorative member 93, and the sealing structure 100 is disposed between the middle sliding rail body 92 and the side wall decorative member 93.

[0033] See also Figure 2In this embodiment, the sealing structure 100 includes a first sealing member 10 and a second sealing member 20. The first sealing member 10 is connected to the middle slide rail body 92, and the second sealing member 20 is connected to the side panel decorative member 93, and the first sealing member 10 and the second sealing member 20 are in contact with each other. The first sealing member 10 and the second sealing member 20 both extend along the front-to-back direction of the vehicle body, that is, the front-to-back direction is the length direction of the first sealing member 10 and the second sealing member 20.

[0034] See also Figure 3 The first sealing member 10 includes a first connecting portion 11, an extending portion 13 and a first abutting portion 12 which are connected end to end. The first connecting portion 11, the extending portion 13 and the first abutting portion 12 are jointly arranged to form a cavity 101. The cavity 101 is strip-shaped. The extending direction of the cavity 101 is also the front-to-back direction, and at least one of the two ends in the front-to-back direction is through-set.

[0035] At least the first abutting portion 12 is elastic and can be elastically deformed toward the cavity 101. The first connecting portion 11 is used to abut the middle slide rail body 92. Specifically, the first connecting portion 11 has a connecting surface 111 facing away from the cavity 101, and the connecting surface 111 abuts against the end surface of the lower end of the middle slide rail body 92. The extension portion 13 extends from the first connecting portion 11 in a direction away from the first structural member. The extension portion 13 is located on the inner side of the first abutting portion 12 and can abut against the side enclosure support 94 of the vehicle. It should be noted that the abutment between the extension portion 13 and the side enclosure support 94 can be direct or indirect, and there is no limitation here.

[0036] The cross-sections of the first connecting portion 11 , the extending portion 13 and the first abutting portion 12 are substantially triangular. The first abutting portion 12 has an abutting surface 121 facing away from the cavity 101 , and the abutting surface 121 is inclined toward the side panel decoration 93 .

[0037] See also Figure 3 The second sealing member 20 includes a second connecting portion 21 and a second abutting portion 22. The second connecting portion 21 is connected to the side panel decoration member 93, specifically connected to the hook 931 of the side panel decoration member 93. The second abutting portion 22 is connected to the second connecting portion 21 and extends from the second connecting portion 21 toward the middle slide rail body 92. The second abutting portion 22 has a first side surface 201 and a second side surface 202 opposite to each other in the thickness direction. The first side surface 201 elastically abuts against the first abutting portion 12. The thickness direction of the second abutting portion 22 is the inside-outside direction of the vehicle. The first side surface 201 faces the inside of the vehicle, and the second side surface 202 faces the outside of the vehicle. Specifically, the abutting direction of the second abutting portion 22 and the first abutting portion 12 is the left-right direction of the vehicle.

[0038] When installing, the sealing structure 100 can elastically abut the first side surface 201 of the second abutting portion 22 of the second sealing member 20 against the first abutting portion 12 located on the outside of the first sealing member 10. Since the cross section formed by the end-to-end connection of the first connecting portion 11, the first abutting portion 12 and the extending portion 13 is roughly triangular, and the deformation position of the first abutting portion 12 is the connection between the first abutting portion 12 and the first connecting portion 11 and the connection with the extending portion 13, the abutting direction of the second abutting portion 22 and the first abutting portion 12 is inclined to the connection direction of the middle slide rail body 92 and the side surround decorative member 93, and the contact area between the second abutting portion 22 and the first abutting portion 12 is large, the sealing effect is good, and the first abutting portion 12 can be moved toward the cavity 1 01 direction deformation to adapt to the pressure applied by the second abutment part 22. When the first seal 10 and the second seal 20 abut against each other, the distance between the middle slide rail body 92 and the side decorative part 93 can be adapted by adjusting the abutment position, abutment area 121 of the second abutment part 22 and the first abutment part 12 and the deformation amount of the first abutment part 12, avoiding the gap and excessive extrusion between the first seal 10 and the second seal 20, thereby avoiding water leakage or abnormal noise when the sliding door 90 is pushed or pulled. At the same time, since the second abutment part 22 is located at the oblique side of the first abutment part 12, the second abutment part 22 will not bend toward one side of the extension part 13 due to extrusion, so there is no need to manually smooth it, which prolongs the service life and saves maintenance costs. In addition, the exposed area of ​​the first seal 10 and the second seal 20 is small, which reduces the risk of aging.

[0039] Optionally, the abutting surface 121 of the first abutting portion 12 is a curved surface to adapt to different abutting directions of the second abutting portion 22 .

[0040] In some embodiments, see Figure 3 The first sealing member 10 further includes a third connecting portion 14 connected to the extension portion 13 and extending in a direction away from the side garnish 93, and the third connecting portion 14 is connected to the inner side of the middle slide rail body 92. In this way, the first sealing member 10 is connected to the middle slide rail body 92 through the third connecting portion 14.

[0041] Optionally, the third connection portion 14 is bonded to the inner side surface of the middle slide rail body 92 to achieve sealing between the third connection portion 14 and the middle slide rail body 92. The first connection portion 11 may only abut against the lower end surface of the middle slide rail body 92 without being connected to the middle slide rail body 92, so as to reduce the requirement for the installation tolerance between the first seal 10 and the middle slide rail body 92.

[0042] In some embodiments, see Figure 3The first sealing member 10 further includes a fourth connecting portion 15 connected to the first connecting portion 11 and spaced apart from the third connecting portion 14. The fourth connecting portion 15 abuts against the outer side surface of the first structural member, and the first connecting portion 11 abuts against the end surface of the first structural member. It can be understood that the third connecting portion 14, the first connecting portion 11 and the fourth connecting portion 15 are jointly arranged to form a groove-like structure, and the lower end of the middle slide rail body 92 is inserted into the groove-like structure. The third connecting portion 14 abuts against the outer side surface of the middle slide rail body 92, the fourth connecting portion 15 abuts against the inner side surface of the middle slide rail body 92, and the first connecting portion 11 abuts against the end surface of the lower end of the middle slide rail body 92. In this way, the third connecting portion 14, the fourth connecting portion 15 and the first connecting portion 11 limit the middle slide rail body 92 from three directions, thereby improving the connection stability between the first sealing member 10 and the middle slide rail body 92.

[0043] In some embodiments, see Figure 3 A groove 102 is provided on the side of the first connection part 11 facing away from the cavity 101. The groove 102 is located between the third connection part 14 and the fourth connection part 15 and is spaced apart from the third connection part 14. The surface of the fourth connection part 15 facing the third connection part 14 is flush with the groove side wall surface of the groove 102. It can be understood that the groove 102 has a first groove side wall close to the third connection part 14 and a second groove side wall away from the third connection part 14. The first groove side wall is directly opposite to the second groove side wall. The groove side wall surface of the first groove side wall is located between the third connection part 14 and the fourth connection part 15. The groove side wall surface of the second groove side wall is flush with the surface of the fourth connection part 15 facing the third connection part 14. The second groove side wall edge of the groove 102 can be used as an extension of the fourth connection part 15. The arrangement of the groove 102 changes the deformation position of the third connection part 14 from the junction of the third connection part 14 and the first connection part 11 to the junction of the second groove side wall of the groove 102 and the groove bottom wall. At the joint, the connecting surface 111 of the first connecting portion 11 abuts against the end surface of the lower end of the middle slide rail body 92. If, due to processing tolerance or installation tolerance, the distance between the third connecting portion 14 and the fourth connecting portion 15 is smaller than the thickness of the lower end of the middle slide rail body 92 or the adhesive between the third connecting portion 14 and the inner side surface of the middle slide rail body 92 is too thick, the outer surface of the middle slide rail body 92 squeezes the fourth connecting portion 15, and the notch of the groove 102 is widened. The fourth connecting portion 15 can always fit with the outer side surface of the middle slide rail body 92, thereby preventing the extended end of the fourth connecting portion 15 from warping outward due to the lower end of the middle slide rail body 92 squeezing the root of the fourth connecting portion 15.

[0044] In some embodiments, see Figure 3The first sealing member 10 further includes a first supporting portion 16 and a second supporting portion 17. The first supporting portion 16 is connected to the junction of the extension portion 13 and the first abutting portion 12 and extends in a direction away from the first abutting portion 12. The second supporting portion 17 is protruding from a side of the third connecting portion 14 away from the first connecting portion 11. As can be understood, the first support portion 16 protrudes from the extension portion 13 toward the door body 91, and the second support portion 17 protrudes from the third connection portion 14 toward the door body 91, and the first support portion 16 and the second support portion 17 are spaced apart, wherein the provision of the second support portion 17 can increase the thickness of the portion of the first seal 10 located before the door body 91 and the middle slide rail body 92, thereby increasing the squeezing force of the second support portion 17 on the third connection portion 14, thereby improving the adhesion force between the third connection portion 14 and the inner side surface of the middle slide rail body 92, and accordingly, the third connection portion 14 also increases the pressure between the second support portion 17 and the door body 91, and strengthens the sealing between the second support portion 17 and the door body 91, and the first support portion 16 can be jointly supported on the door body 91 of the vehicle with the second support portion 17 to form a two-layer sealing ring, thereby strengthening the sealing between the first seal 10 and the door body 91 and preventing water leakage between the first seal 10 and the door body 91.

[0045] Optionally, the first support portion 16 and the second support portion 17 may be elastic. For example, the first support portion 16 and the second support portion 17 are both rubber parts to adapt to different distances between the middle slide rail body 92 and the door body 91, reducing the requirements for installation errors. At the same time, the first support portion 16 and the second support portion 17 can increase the friction between the door body 91 in the extrusion state, thereby improving the sealing stability between the first seal 10 and the door body 91.

[0046] Of course, in other embodiments, the first support portion 16 and the second support portion 17 may also be made of hard materials. In this case, the first support portion 16 and the second support portion 17 may be interference fit with the door body 91 .

[0047] In some embodiments, the first abutting portion 12 may be a first abutting portion 12 made of a rubber material, so as to be deformed toward the cavity 101, and the rubber material is relatively dense, which improves the structural strength of the first sealing member 10. The first sealing member 10 also includes a sponge rubber connected to the side of the first abutting portion 12 away from the first connecting portion 11, and the first side surface 201 elastically abuts against the sponge rubber. At this time, the second abutting portion 22 abuts against the first abutting portion 12 through the sponge rubber. The sponge rubber can be compressed and deformed in the thickness direction to absorb the pressure of the second abutting portion 22, thereby reducing the deformation of the first abutting portion 12 toward the cavity 101 and improving the service life of the first sealing member 10.

[0048] Optionally, the middle portion of the first abutting portion 12 may be arched in a direction away from the cavity 101 to provide greater support for the second sealing member 20. Accordingly, the abutting surface 121 thereof may be a combination of one or more of an arc surface, a folded surface or a plane.

[0049] In some embodiments, the first abutting portion 12, the first connecting portion 11, the extending portion 13, the third connecting portion 14, the fourth connecting portion 15, the first supporting portion 16 and the second supporting portion 17 are all made of rubber and are integrally formed for easy processing. In this case, the first abutting portion 12, the first connecting portion 11 and the extending portion 13 can form a bubble tube together.

[0050] In some embodiments, see Figure 3 The first sealing member 10 further includes a fiber filament 18 embedded in the joint of the first connecting portion 11 and the extending portion 13 , and the fiber filament 18 extends along the length direction of the first sealing member 10 to improve the structural strength of the first sealing member 10 in the length direction thereof.

[0051] In some embodiments, see Figure 3 The connection between the second connecting portion 21 and the second abutting portion 22 has an angle, so that the deformation position of the second abutting portion 22 is the angle, which facilitates the second abutting portion 22 to rotate and deform outward with the connection between the second connecting portion 21 and the second abutting portion 22 as the center point.

[0052] Optionally, the first side surface 201 of the second abutment portion 22 is an arc surface, and the middle part thereof is arched in a direction away from the first seal 10 to increase the contact area between the first side surface 201 and the abutment surface 121 of the first abutment portion 12, thereby preventing the extending end of the second abutment portion 22 from warping in a direction away from the first seal 10.

[0053] Optionally, the second connecting portion 21 and the second abutting portion 22 may be an integrally formed rubber member, which is convenient for processing and improves the reliability of the second sealing member 20. The second abutting portion 22 may be formed on the hook 931 of the side panel decorative member 93 by injection molding.

[0054] The above are only some specific embodiments of the utility model, which only specifically describe the technical principles of the utility model. These descriptions are only for explaining the principles of the utility model and cannot be interpreted as limiting the protection scope of the utility model in any way. Based on the explanation here, any modifications, equivalent substitutions and improvements made within the spirit and principles of the utility model, and other specific implementation methods of the utility model that can be associated with the technicians in this field without creative work, should be included in the protection scope of the utility model.
