Description

Technical Field

[0001] The utility model relates to the technical field of vehicles, and in particular to a body hole sealing structure. The utility model also relates to a vehicle provided with the body hole sealing structure. Background Art

[0002] In a car body, some holes are often provided due to design or later preparation and assembly needs. Taking the car door in the car body as an example, a car body hole structure composed of sheet metal vias is often provided on the door sheet metal.

[0003] Currently, after assembly is completed, sheet metal vias and other hole structures on vehicle doors are generally sealed with waterproof films. However, traditional waterproof films are mostly opaque. When bonding the waterproof film to the door sheet metal, due to the opaque nature of the waterproof film, it is difficult for workers to determine whether the waterproof film is well bonded, which is not conducive to ensuring the sealing of the hole positions of the vehicle body.

[0038] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0039] Embodiment 1

[0040] The present embodiment relates to a vehicle body hole sealing structure (referred to as "sealing structure"), which is used to block and seal a hole structure located on a vehicle body and helps to ensure the sealing of the vehicle body hole position.

[0041] Among them, in this embodiment, the hole structure on the vehicle body can be, for example, a structure such as a sheet metal via in a vehicle door or on a door sheet metal. In addition to the sheet metal via on the vehicle door, of course, the vehicle body holes in this embodiment can also be sheet metal vias on other sheet metals in the vehicle body, or a via structure formed by the sheet metal and adjacent surrounding components.

[0042] After the door or body is assembled, the various hole structures in the above-mentioned body can be sealed by the sealing structure of this embodiment to avoid problems such as water leakage and airtightness leakage at the hole position of the body.

[0043] It is worth pointing out that in the prior art, waterproof membranes are generally used to seal holes on vehicle bodies, and the waterproof membranes used are mainly polyethylene foam membranes, or a composite structure composed of PE (Polyethylene) membrane and EPDM (Ethylene Propylene Diene Monomer) foam, wherein the EPDM foam is located in the middle, and the PE membrane is arranged around the edge of the EPDM foam, and is also bonded through the surrounding PE membrane.

[0044] However, on the one hand, the existing waterproof membranes are all opaque. When bonding, due to the opacity of the bonding area, it will be difficult for workers to judge whether the waterproof membrane is bonded intact, which is not conducive to ensuring the sealing of the holes in the body, and it is easy to cause water leakage and airtightness problems in the holes in the body. On the other hand, still taking the sealing of hole structures such as sheet metal vias on car doors as an example, for waterproof membranes composed of a composite structure of PE membrane and EPDM foam, when the audio installed on the car door is working, it will also cause the waterproof membrane to resonate, produce abnormal noise, and damage the audio quality. At the same time, the cost of EPDM foam is relatively high, which is of course not conducive to the cost control of the entire vehicle.

[0045] Therefore, this embodiment is to solve the problems existing in the waterproof membrane in the prior art, and to make an innovative design for the currently used waterproof membrane, and in terms of the overall structure, combined with Figures 1 to 4 As shown in , the sealing structure of this embodiment includes a structural body 100 , and the structural body 100 also specifically includes a main body portion 1 located in the middle, and a lip portion 2 arranged around at least a portion of the edge of the main body portion 1 .

[0046] Among them, the lip portion 2 further includes a first lip 21 and a second lip 22 stacked together, the first lip 21 and the second lip 22 are connected to the main body 1 on the same side, and a glue coating surface s is provided on the side of the first lip 21 facing away from the second lip 22, and a glue overflow channel is also provided on the first lip 21.

[0047] The above-mentioned glue overflow channel is arranged corresponding to the glue coating surface s, and the glue overflow channel also penetrates the first lip edge 21 along the thickness direction of the structural body 100 .

[0048] At this time, as set above, by providing the lip portion 2 in the structural body 100 with two layers of lips, namely the first lip 21 and the second lip 22, and providing a through-shaped overflow glue channel on the first lip 21 having the glue coating surface s, this embodiment can judge the bonding condition by the overflow of glue in the overflow glue channel during bonding, and can also connect the two layers of lips through the overflow of glue at the overflow glue channel, which helps to avoid poor bonding problems that are easily caused by difficult observation, so as to ensure the sealing of the hole position of the vehicle body.

[0049] Based on the above overall introduction, specifically, Figure 1 and Figure 2 As shown in , preferably, the structural body 100 of this embodiment can be in sheet shape. The main body 1 can be generally designed in accordance with the shape of the hole in the vehicle body, and as a preferred implementation form, generally speaking, the lip portion 2 as the edge of the structural body 100 can be set as a circle set around the edge of the main body 1, so that the sealing structure of this embodiment can be realized by using the entire circle of the lip portion 2, and the reliable bonding with the edge position of the circumference of the hole in the vehicle body can ensure the stability of the sealing structure set at the hole in the vehicle body.

[0050] However, in addition to making the lip portion 2 a circle around the edge of the main body 1, it is understandable that in some other embodiments, the lip portion 2 can also be set only around a part of the edge of the main body 1. At this time, when the body hole is blocked and sealed, as a feasible example, the position with the lip portion 2 can still be connected to the edge of the body hole by gluing, and for the position without the lip portion 2, it can be clamped by overlapping body sheet metal, or the body sheet metal and other adjacent peripheral parts can be clamped together, so that the main body 1 is directly sealed with the body structure, and the connection between the lip portion 2 and the body is coordinated to achieve the sealing of the body hole position.

[0051] In the present embodiment, it is worth noting that the above-mentioned glue overflow channel is set corresponding to the glue coating surface s, that is, from the perspective of the thickness direction of the structural body 100, the projection of the glue overflow channel and the glue coating surface s in the thickness direction of the structural body 100 coincides, and it is based on the corresponding setting between the glue overflow channel and the glue coating surface s that when the glue overflow channel passes through the first lip edge 21, its mouth located on the side of the glue coating surface s is also located on the glue coating surface s.

[0052] In addition, during the specific implementation, as a preferred implementation form, continue as follows Figure 1 and Figure 2 As shown in , the above-mentioned glue overflow channel may include, for example, a through hole 3 provided on the first lip 21, and the through hole 3 is also specifically a plurality of through holes 3 arranged at intervals along the length direction of the first lip 21. The length direction of the above-mentioned first lip 21 is of course the direction in which the first lip 21 surrounds the edge of the main body 1.

[0053] At this time, by making the overflow glue channel adopt a plurality of through holes 3 arranged at intervals on the first lip edge 21, it can be understood that it obviously has the characteristics of simple structure and convenient design and molding.

[0054] However, in addition to setting the overflow glue channel as a plurality of through holes 3 arranged on the first lip 21, of course, in some feasible implementation forms, for example, the overflow glue channel can also be set as a slot or other structure that also passes through the first lip 21. Moreover, taking the overflow glue channel as a slot as an example, the slot can also be a plurality of slots arranged at intervals along the length of the first lip 21, each slot extending along the width direction of the first lip 21, and at the same time, one end of each slot can be close to the main body 1, and the other end thereof can pass through the edge of the first lip 21.

[0055] In this embodiment, the through hole 3 is used as an example for the overflow glue channel. It should be pointed out that in the specific implementation, the through hole 3 can generally be set as follows: Figure 1 and Figure 2What is shown is only one row arranged along the length direction of the first lip 21. However, when the width of the lip portion 2, that is, the first lip 21 and the second lip 22, is larger, it is of course possible to arrange the through holes 3 spaced apart along the length direction of the first lip 21 in two parallel rows or other numbers.

[0056] In addition, for the through holes 3 in the same row, the distance between two adjacent through holes 3 in the length direction of the first lip 21 can be determined according to the aperture size of each through hole 3 and the connection strength between the lip portion 2 and the vehicle body.

[0057] Generally speaking, the aperture of the through hole 3 may be, for example, between 1 mm and 5 mm, and specifically, it may be, for example, 1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm or 3.5 mm, etc. The spacing between two adjacent through holes 3 may be, for example, between 5 mm and 15 mm, and specifically, it may be 5 mm, 7.5 mm, 8 mm, 10 mm, 12 mm, 15 mm, etc., according to the aperture size of the through hole 3, etc.

[0058] In addition, in the specific implementation, as a preferred implementation form, in this embodiment, for the through holes 3 in the same row, multiple through holes 3 can also be evenly arranged in the length direction of the first lip 21. In this way, by evenly arranging multiple through holes 3, it is helpful to ensure the reliability of the connection between the two lips when the first lip 21 and the second lip 22 are connected through the overflow glue at the through holes 3, thereby improving the sealing effect of the hole position of the vehicle body.

[0059] In this embodiment, as a preferred implementation form, when the overflow glue channel is composed of a plurality of through holes 3, in the specific implementation, for example, the cross section of each through hole 3 can be circular. In this way, the cross section of the through hole 3 is circular. Obviously, compared with shapes such as square, triangle or star, it can make full use of the feature that the edges of the circular hole are all smoothly transitioned. While the through hole 3 is provided, it can avoid the formation of easy-tear points at the through hole 3, thereby ensuring the reliability of the structure of the first lip 21.

[0060] However, in addition to the preferred configuration of the through hole 3 being a circular hole, in other feasible implementation forms, the through hole 3 may also be a through hole structure of other shapes. Specifically, for example, the through hole 3 may be in an elongated strip or elliptical shape, and when the through hole 3 is in an elongated strip shape, both ends of the through hole 3 in the length direction should also be designed as a smoothly transitioned arc structure to avoid the generation of easy-tear points at the through hole 3 as much as possible, which would adversely affect the structural reliability of the first lip 21.

[0061] In this embodiment, based on the sheet-like shape of the structural body 100 , in the thickness direction of the structural body 100 , the thickness of the first lip 21 and the second lip 22 in the lip portion 2 can be set to be half the thickness of the main body 1 , for example.

[0062] At this time, the thickness of the two lips is half of the thickness of the main body 1. It can be understood that it can make the structural body 100 have the same overall thickness at all positions, thereby saving the material cost of the sealing structure. However, in addition to making the thickness of the first lip 21 and the second lip 22 half of the thickness of the main body 1, of course, in some other embodiments, only one of the first lip 21 and the second lip 22 has a thickness of half of the thickness of the main body 1, and the thickness of the other lip is less than or greater than the thickness of the main body 1 according to design requirements. This is also possible.

[0063] In addition, it is worth noting that, in the specific implementation, the thickness of the structural body 100 of this embodiment, that is, the thickness of the main body 1 and the two lips in the lip portion 2, can be selected based on the material used in the sealing structure and the sealing requirements of the hole position of the vehicle body. Generally speaking, the thickness of the main body 1 can be, for example, 2mm-10mm, so that the thickness of the first lip 21 and the second lip 22 can be, for example, between 1mm-5mm, and specifically, for example, the thickness of the main body 1 can be 2mm, 4mm, 5mm, 6mm, 7mm, 8mm or 10mm, etc., the thickness of the first lip 21 and the second lip 22 can be 1mm, 2mm, 3mm, 4mm or 5mm, etc., and the thickness of the two lips can be adjusted according to the thickness of the main body 1.

[0064] In this embodiment, during specific implementation, as a preferred implementation form, the structural body 100 can be made of XPE (Chemical crosslinked polyethylene foam) material, for example.

[0065] XPE material is made of low-density polyethylene resin, cross-linking agent and foaming agent through high-temperature continuous foaming. It has the characteristics of low density, softness, good elasticity, as well as wear resistance, heat insulation, sound insulation and waterproofness.

[0066] At the same time, compared with EPE (Expandable Polyethylene, physical foamed polyethylene, commonly known as pearl cotton), XPE material has higher tensile strength and finer pores. Compared with other PE or non-PE materials, XPE material also has excellent performance in durability, light resistance, physical impact resistance, etc. In addition, the chemical properties of XPE material itself are stable, and it has the advantages of not easy to decompose, no odor, good elasticity, etc.

[0067] In addition, XPE material not only has certain cost advantages compared to EPDM foam, but also will not resonate with the audio system on the door (i.e., the speaker installed on the door) when it is installed on the door.

[0068] Thus, it can be understood that by making the structural body 100 of this embodiment, that is, the sealing structure of this embodiment, made of XPE material, it is obviously helpful to reduce the material cost compared with the existing waterproof membrane made of EPDM material. Moreover, when the sealing structure of this embodiment is used on the car door, it can also avoid the resonance between the sealing structure and the sound, avoid the generation of abnormal sound, and help to ensure the sound quality.

[0069] In this embodiment, the overflow glue channel is still made of through hole 3, and the sealing structure is made of XPE material as an example. In the specific preparation, the first lip 21 and the second lip 22 in the lip portion 21 can be prepared at the same time when the structural body 100 is foamed, and then the through holes 3 are formed on the first lip 21. Alternatively, after the structural body 100 is foamed, the two lips in the lip portion 2 can be machined first, and then the through holes 3 can be formed on the first lip 21.

[0070] Furthermore, it is worth noting that Figures 1 to 4 In the figure, the opening k between the first lip 21 and the second lip 22 is mainly used to better illustrate that the lip portion 2 at the edge is composed of two lips. In specific implementation, depending on the different materials used by the structural body 100, of course, in some cases, the first lip 21 and the second lip 22 may not be forked to form the opening k therebetween.

[0071] The specific operation process of the sealing structure of this embodiment when in use can refer to the description in the following embodiment 2.

[0072] At the same time, the sealing structure of this embodiment adopts the above design, which makes the lip portion 2 located at the edge of the structural body 100 adopt two layers of lips, and sets a glue overflow channel on the lip with the glue coating surface s, so that not only can the bonding condition be judged by the glue overflow in the glue overflow channel during bonding, but also the two layers of lips can be connected by the glue overflow. The sealing structure of this embodiment helps to avoid the problem of poor bonding that is easily caused by difficult observation, helps to ensure the sealing of the body hole position, and can ensure the sound insulation performance and air tightness of the body hole.

[0073] Embodiment 2

[0074] The present embodiment relates to a vehicle, wherein a body hole is arranged on the body of the vehicle, and the body hole sealing structure of the first embodiment is arranged at at least one of the body holes.

[0075] Among them, in this embodiment, combined with the description in the first embodiment, the above-mentioned body hole can be, for example, a sheet metal through hole on a door sheet metal in a door, or the above-mentioned body hole can also be a through hole structure at other positions in the body.

[0076] In addition, in this embodiment, when the above-mentioned sealing structure is set at the position of the hole in the vehicle body, adhesive is first applied on the adhesive coating surface s of the first lip 21, and then the first lip 21 is bonded to the edge of the hole in the vehicle body through the adhesive on the adhesive coating surface s. In this process, part of the adhesive will overflow through the overflow channel on the first lip 21, that is, each through hole 3, and the bonding condition between the first lip 21 and the vehicle body can be judged by the overflow condition of each through hole 3.

[0077] Specifically, if a certain amount of glue overflow occurs at the through hole 3, it means that the first lip 21 at the location of the through hole 3 and the vehicle body can be well bonded together. If the glue overflow at the through hole 3 is less, or even no glue overflow occurs, it means that the amount of glue applied at the location of the through hole 3 is insufficient, which may result in a poor bonding effect between the first lip 21 at this location and the vehicle body.

[0078] When the overflow of glue at each through hole 3 meets the relevant requirements, it means that the first lip 21 has been bonded, and then the second lip 22 is pressed so that the second lip 22 is bonded to the first lip 21 through the overflowed adhesive. Moreover, in order to ensure the bonding effect between the second lip 22 and the first lip 21, in addition to the adhesive overflowing from each through hole 3, of course, when bonding the second lip 22, glue can also be further applied on the side of the first lip 21 facing the second lip 22 to ensure the amount of glue between the second lip 22 and the first lip 21.

[0079] The vehicle of this embodiment adopts the sealing structure of the first embodiment, which helps to avoid the problem of poor adhesion of the body hole sealing structure due to difficulty in observation, is beneficial to ensure the sealing of the body hole position, and when used for sealing the hole structure on the door, it can also avoid the generation of abnormal noise due to resonance with the sound, and has a good application effect.

[0080] 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.
