Description

Technical Field

[0001] This utility model relates to the field of vehicle sealing technology, and in particular to a matching structure for wheel flange sealing strips for car doors and automobiles. Background Technology

[0002] Wheel flange seals are an important component of the automotive sealing system. As people's requirements for automotive comfort, NVH, and perception are getting higher and higher, in order to meet these increasingly better demands, the design of wheel flange seals should be simple in structure and reduce the number of matching parts. This is an important goal in the current design of wheel flange seals.

[0003] In existing door rim sealing strip matching structures, the rim sealing strip is installed onto the door sheet metal via clips. The outer side of the rim sealing strip fits snugly against the door skirt panel, while the inner side interferes with the side skirt panel to achieve a fastening and sealing function. The side skirt panel is then installed on the side sheet metal. This design requires the rim sealing strip to match the dimensions of multiple surrounding parts, resulting in a complex overall structure that is difficult to manufacture.

[0004] In addition, in order to cover the door sheet metal, the existing wheel flange sealing strips usually achieve the matching with the door sheet metal through an inverted structure. However, the inverted structure increases the difficulty of manufacturing wheel flange sealing strips and the difficulty of installation and matching, resulting in increased production and installation costs, which is not conducive to its widespread use. Utility Model Content

[0005] The purpose of this utility model is to provide a matching structure for wheel rim sealing strips for car doors, which solves the problem of complex structure and increased production and installation costs caused by the existing wheel rim sealing strip matching structure, which requires the wheel rim sealing strip to be matched with the size of the surrounding parts, especially by using an inverted structure to match with the car door sheet metal.

[0006] To achieve the above objectives, this utility model provides a matching structure for a wheel rim sealing strip for a car door, comprising a car door skirt panel, a car door sheet metal, a side panel sheet metal, a buckle, and a wheel rim sealing strip;

[0007] The side panel sheet metal, door sheet metal, and door skirt panel are arranged sequentially along a first direction. A first gap extending in a second direction is formed between one end of the door sheet metal and the door skirt panel. A second gap extending in the first direction is formed between the side panel sheet metal and the door sheet metal.

[0008] The wheel rim sealing strip is disposed in the second gap, and the wheel rim sealing strip includes a supporting body, a shielding body, and an abutting body; the supporting body extends along the second direction, the abutting body is connected to the side of the supporting body facing away from the door sheet metal, and the end of the abutting body away from the supporting body can cover and elastically connect to one end of the side sheet metal; the supporting body is fixedly connected to the door sheet metal by a buckle;

[0009] The shield is fixed to the support body at one end away from the buckle. The shield is attached to the end of the door sheet metal near the first gap and at least partially extends into the first gap to shield the door sheet metal.

[0010] Wherein, the first direction is perpendicular to the second direction.

[0011] Furthermore, the shielding body includes a connected fitting section and a first extension section;

[0012] The fitting section is fixedly connected to one end of the support body away from the buckle, and fits against one end of the door sheet metal near the first gap;

[0013] The first extension segment is fixedly connected to the side of the fitting segment away from the support body and extends outward to be embedded in the first gap, thereby covering the door sheet metal.

[0014] Furthermore, in the first direction, the end of the first extension is flush with the end face of the door sheet metal facing away from the side sheet metal.

[0015] Furthermore, the abutment includes a first end, a second end, and a third end connected to the first end and the second end. The first end and the second end are spaced apart and connected to the support body. The third end can cover and elastically connect to one end of the side panel sheet metal to cover the side panel sheet metal.

[0016] Furthermore, the supporting body and the abutting body together enclose a cavity, and a filling material is provided in the cavity.

[0017] Furthermore, the third end is fixed with a second extension section disposed near the end of the side panel sheet metal;

[0018] The second extension can elastically contact the end of the side panel sheet metal and squeeze the filler so that the second extension covers the end of the side panel sheet metal, thereby covering the side panel sheet metal.

[0019] Furthermore, the side of the abutment away from the buckle is recessed into an arc shape.

[0020] Furthermore, in the first direction, the end of the second extension is flush with the end face of the side panel sheet metal facing away from the door sheet metal.

[0021] Furthermore, the support body and the shielding body are made of EPDM solid adhesive;

[0022] The abutment is made of EPDM foam adhesive.

[0023] This utility model also provides an automobile that includes the above-described wheel rim sealing strip matching structure.

[0024] The wheel flange sealing strip matching structure provided by this utility model for car doors, compared with the prior art, has the following advantages:

[0025] This utility model provides a matching structure for a wheel rim sealing strip for a car door, comprising a door skirt panel, a door sheet metal, a side panel sheet metal, a buckle, and a wheel rim sealing strip. The wheel rim sealing strip is disposed in a second gap between the door sheet metal and the side panel sheet metal to seal the second gap during operation. The support body is fixedly connected to the door sheet metal by the buckle to achieve a fixed connection between the wheel rim sealing strip and the door sheet metal. By setting a shielding body and having the shielding body abut against the end of the door sheet metal near the first gap and at least partially extending and embedding into the first gap, the door sheet metal is shielded. Compared with the inverted snap structure in the prior art, the shielding body does not need to consider the size matching with the door sheet metal; it only needs to be embedded in the first gap by at least part of the shielding body, simplifying the structure of the wheel rim sealing strip. Furthermore, using side panel sheet metal instead of the side skirt panel in the prior art to cooperate with the wheel rim seal strip reduces the number of peripheral parts in the wheel rim seal strip matching structure; and by having the end of the abutment body away from the support body able to cover and elastically connect to one end of the side panel sheet metal, the side panel sheet metal is shielded to protect it. Thus, by using the shielding body to shield the door sheet metal to simplify the structure of the wheel rim seal strip, and by using side panel sheet metal instead of side skirt panel to cooperate with the wheel rim seal strip to reduce the number of peripheral parts in the wheel rim seal strip matching structure, the design and production difficulty of the wheel rim seal strip is simplified, and the assembly difficulty of the wheel rim seal strip matching structure is reduced, thereby reducing production and installation costs and facilitating widespread use.

[0026] This utility model also provides an automobile that includes the above-mentioned wheel rim sealing strip matching structure. Through the above-mentioned wheel rim sealing strip matching structure, the automobile including the wheel rim sealing strip matching structure can achieve the purpose of fastening and sealing the door while making the wheel rim sealing strip matching structure simple and easy to install.

Detailed Implementation

[0031] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0032] like Figures 1-3 As shown, an embodiment of the present invention provides a wheel rim sealing strip matching structure 100 for a car door, which includes a car door skirt panel 1, a car door sheet metal 2, a side panel sheet metal 3, a buckle 4, and a wheel rim sealing strip 5.

[0033] The side panel 3, the door panel 2, and the door skirt panel 1 are arranged sequentially along the first direction X. A first gap 10 extending in the second direction Y is formed between one end of the door panel 2 and the door skirt panel 1. A second gap 20 extending in the first direction X is formed between the side panel 3 and the door panel 2.

[0034] The wheel rim sealing strip 5 is disposed in the second gap 20. The wheel rim sealing strip 5 includes a supporting body 51, a shielding body 52, and an abutting body 53. The supporting body 51 extends along the second direction X. The abutting body 53 is connected to the side of the supporting body 51 facing away from the door sheet metal 2, and the end of the abutting body 53 away from the supporting body 51 can cover and elastically connect to one end of the side panel sheet metal 3. The supporting body 51 is fixedly connected to the door sheet metal 2 by a buckle 4.

[0035] The shield 52 is fixed on the support body 51 at one end away from the buckle 4. The shield 52 is attached to the end of the door sheet metal 2 near the first gap 10 and at least partially extends into the first gap 10 to shield the door sheet metal 2.

[0036] Wherein, the first direction X is perpendicular to the second direction Y.

[0037] Based on the above technical solution, the wheel flange sealing strip 5 is disposed in the second gap 20 between the door sheet metal 2 and the side sheet metal 3 to seal the second gap 20 during operation. The support body 51 is fixedly connected to the door sheet metal 2 by a buckle 4 to achieve a fixed connection between the wheel flange sealing strip 5 and the door sheet metal 2. By setting a shielding body 52 and making the shielding body 52 fit against the end of the door sheet metal 2 near the first gap 10, and at least partially extending and embedding into the first gap 10, the shielding of the door sheet metal 2 is achieved. Compared with the inverted structure in the prior art, the shielding body 52 does not need to consider the size matching with the door sheet metal 2, and only needs to be embedded in the first gap 10, which simplifies the structure of the wheel flange sealing strip 5. Furthermore, using a side panel 3 instead of the side skirt panel in the prior art to cooperate with the wheel rim sealing strip 5 reduces the number of peripheral parts in the wheel rim sealing strip matching structure; and by having the end of the abutment 53 away from the support body 51 cover and elastically connect to one end of the side panel 3, the side panel 3 is shielded to protect it. Thus, the shielding body 52 simplifies the structure of the wheel rim sealing strip 5 by shielding the door panel 2, and the use of a side panel 3 instead of the side skirt panel reduces the number of peripheral parts in the wheel rim sealing strip matching structure, thereby simplifying the design and production difficulty of the wheel rim sealing strip 5 and reducing the assembly difficulty of the wheel rim sealing strip matching structure 100, thereby reducing production and installation costs and facilitating widespread use.

[0038] Furthermore, such as Figures 1-3 As shown, to facilitate the specific implementation of at least a portion of the shielding body 52 fitting against the end of the door sheet metal 2 near the first gap 10, at least a portion of the shielding body 52 is embedded in the first gap to shield the door sheet metal 2; the shielding body 52 includes a fitting section 521 and a first extension section 522 connected together; the fitting section 521 is fixedly connected to the end of the support body 51 away from the buckle 4, and fits against the end of the door sheet metal 2 near the first gap 10; the first extension section 522 is fixedly connected to the side of the fitting section 521 away from the support body 51, and extends outward to fit into the first gap 10, thereby shielding the door sheet metal 2.

[0039] Preferably, such as Figure 1 and Figure 2 As shown, the first extension section 522 is separated from the door skirt panel 1 to reduce assembly difficulty.

[0040] Furthermore, such as Figure 1 and Figure 2 As shown, in the first direction X, the end of the first extension segment 522 is flush with the end face of the door sheet metal 2 facing away from the side panel sheet metal 3 to determine the size of the first extension segment 522. The flush arrangement ensures that the first extension segment 522 can completely cover the door sheet metal 2, while preventing the first extension segment 522 from colliding with the outer edge of the door sheet metal 2 or the door skirt panel 1 due to the first extension segment 522 being longer than the door sheet metal 2, thereby causing abnormal noise or other problems affecting the use.

[0041] Furthermore, such as Figures 1-3 As shown, since the abutment 53 is used to abut and support between the support body 51 and the side sheet metal 3, in order for the abutment 53 to simultaneously have an abutment support structure and for the end of the abutment 53 away from the support body 51 to cover and elastically connect to the end of the side sheet metal 3, the abutment 53 includes a first end 531, a second end 532, and a third end 533 connected to the first end 531 and the second end 532. The first end 531 and the second end 532 are spaced apart and connected to the support body 51 to form a support abutment structure; the third end 533 can cover and elastically connect to the end of the side sheet metal 3 to cover the side sheet metal 3.

[0042] Furthermore, to facilitate the production and processing of the abutment body 53, a gap is provided between the first end 531 and the second end 532, so that the support body 51 and the abutment body 53 together enclose a cavity, and a filler 54 is provided in the cavity; thereby facilitating the production and processing of the wheel rim sealing strip 5.

[0043] Furthermore, to facilitate the shielding of the side sheet metal 3 by the abutment body 53, the third end 533 is fixedly provided with a second extension section 534 located near the end of the side sheet metal 3; wherein, the second extension section 534 can elastically contact the end of the side sheet metal 3 and compress the filler 54, so that the second extension section 534 covers the end of the side sheet metal 3, thereby shielding the side sheet metal 3, thus eliminating the need for detailed calculation of matching dimensions during the design process to achieve the effect of the second extension section 534 covering the end of the side sheet metal 3, and simplifying the structure and design of the wheel rim sealing strip 5.

[0044] Furthermore, such as Figures 1-3As shown, in order to ensure that the second extension 534 can properly elastically contact the side panel sheet 3 during operation and thus cover the end of the side panel sheet 3, the side of the abutment 53 away from the buckle 4 is recessed and has an arc surface.

[0045] Furthermore, such as Figures 1-3 As shown, in order to avoid the second extension section 534 having an excess portion that could further cause abnormal noise, scratches and other problems, in the first direction X, the end of the second extension section 534 is flush with the end face of the side panel sheet metal 3 facing away from the door sheet metal 2.

[0046] Furthermore, since the supporting body 51 and the shielding body 52 mainly serve to connect and shield, and the abutting body, in addition to shielding, needs to have a certain strength to achieve a seal between the door sheet metal 2 and the side sheet metal 3, the supporting body 51 and the shielding body 52 are made of EPDM solid adhesive; the abutting body 53 is made of EPDM sponge adhesive.

[0047] Preferably, the filler 54 is made of EPDM foam to provide sufficient strength to support compression deformation during operation.

[0048] Preferably, the buckle 4 is made of PP plastic, which is an readily available production material and can reduce the production cost of the buckle 4.

[0049] This utility model also provides an automobile that includes the above-described wheel rim sealing strip matching structure 100.

[0050] Based on the above technical solution, the automobile including the wheel flange sealing strip matching structure 100 can achieve the goal of fastening and sealing the door while making the wheel flange sealing strip matching structure simple and easy to install.

[0051] The working process of this utility model is as follows: the support body 51 is fixedly connected to the car door sheet metal 2 by the buckle 4; the first extension section 522 covers the car door sheet metal 2 to prevent the car door sheet metal 2 from being exposed;

[0052] The second extension section 534 makes elastic contact with the side panel 3, squeezing the filler 54. Through the support of the filler 54 and the abutment 53, the second extension section 534 covers the side panel 3, preventing the door panel 2 from being exposed.

[0053] In summary, this utility model embodiment provides a wheel rim sealing strip matching structure 100 for a car door, which includes a door skirt panel 1, a door sheet metal 2, a side panel sheet metal 3, a buckle 4, and a wheel rim sealing strip 5. The wheel rim sealing strip 5 is disposed in a second gap 20 between the door sheet metal 2 and the side panel sheet metal 3 to seal the second gap 20 during operation. The support body 51 is fixedly connected to the door sheet metal 2 by the buckle 4 to achieve a fixed connection between the wheel rim sealing strip 5 and the door sheet metal 2. By setting a shielding body 52 and making the shielding body 52 fit against the end of the door sheet metal 2 near the first gap 10, and at least partially extending and embedding into the first gap 10, the shielding of the door sheet metal 2 is achieved. Compared with the inverted snap structure in the prior art, the shielding body 52 does not need to consider the size matching with the door sheet metal 2, and only needs to be embedded in the first gap 10, which simplifies the structure of the wheel rim sealing strip 5. Furthermore, using a side panel 3 instead of the side skirt panel in the prior art to cooperate with the wheel rim sealing strip 5 reduces the number of peripheral parts in the wheel rim sealing strip matching structure; and by having the end of the abutment 53 away from the support body 51 cover and elastically connect to one end of the side panel 3, the side panel 3 is shielded to protect it. Thus, the shielding body 52 simplifies the structure of the wheel rim sealing strip 5 by shielding the door panel 2, and the use of a side panel 3 instead of the side skirt panel reduces the number of peripheral parts in the wheel rim sealing strip matching structure, thereby simplifying the design and production difficulty of the wheel rim sealing strip 5 and reducing the assembly difficulty of the wheel rim sealing strip matching structure 100, thereby reducing production and installation costs and facilitating widespread use.

[0054] This utility model also provides an automobile that includes the above-mentioned wheel rim sealing strip matching structure 100. Through the wheel rim sealing strip matching structure 100, the automobile including the wheel rim sealing strip matching structure 100 can achieve the purpose of achieving door fastening and sealing while the wheel rim sealing strip matching structure is simple and easy to install.

[0055] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
