Description

Technical Field

[0001] The present application belongs to the field of vehicle technology, and specifically relates to a sealing module, a vehicle body and a vehicle. Background Art

[0002] The body of a car that's been welded but not yet painted is called the body-in-white (BIW). The side panels of the BIW contain enclosed box-shaped reinforcement beams. These structures, such as the A-pillars, B-pillars, and C-pillars, as well as the door sills, front panels, and side panels, all contain numerous cavities. When a car travels at high speeds, high-speed airflow is generated within these cavities, generating wind noise that transmits external noise, causing intense noise and vibration for the driver and passengers, thereby reducing the vehicle's NVH (Noise, Vibration, and Harshness) performance.

[0003] To solve the above problems, a plywood is usually installed in the cavity to block the transmission of airflow in the cavity, so as to reduce harsh noise, make the car interior quieter, and thus improve ride comfort.

[0004] However, the unreasonable arrangement or design of the sealing module may result in the inability to completely and effectively seal the cavity or affect the electrophoretic performance of the cavity, as well as blocking the welding gun and increasing the welding length, which may cause the car cavity to be easily corroded or allow outside noise and water to enter the passenger compartment, reducing the car's service life and ride comfort.

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0040] The sealing module, vehicle body and vehicle provided in the embodiments of the present application are described in detail below with reference to specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0041] See also Figures 1 to 10 An embodiment of the present application provides a sealing module, which includes a blocking structure and a first filling piece 30. The blocking structure is connected to the vehicle body, and the first filling piece 30 is connected to the blocking structure to achieve filling between the blocking structure and the vehicle body.

[0042] In the embodiments of the present application, installing the sealing module on the vehicle body effectively blocks airflow entering through the vehicle body, thereby improving the overall vehicle comfort. In practical applications, the cavity within the vehicle body contains space, and the connection between the sealing module and the vehicle body often has some gaps. This gap allows airflow to pass through it, causing varying degrees of noise. The first filler 30 is provided to fill this gap, effectively blocking airflow entering through it. This improves the seal between the vehicle body and the sealing module, thereby enhancing the vehicle's NVH performance and improving the user experience.

[0043] It should be noted that the first filling member 30 can be one or more of spot welding glue, structural glue, expansion glue, and hemming glue, or other materials that can be used to fill the gap between the car body and the sealing module. This embodiment does not impose any limitation on this.

[0044] Optionally, in an embodiment of the present application, the blocking structure includes a skeleton component 10 and a second filler 20, and the second filler 20 is connected to the skeleton component 10; wherein, the end of the second filler 20 is provided with a sharp corner 21, and the sharp corner 21 is connected to the first filler 30, and the first filler 30 is matched with the vehicle body.

[0045] In the embodiment of the present application, the setting of the skeleton component 10 is used to provide an attachment object for the second filler 20 and the first filler 30. At the same time, the setting of the skeleton component 10 can also be used to improve the support performance of the sealing module. The second filler 20 is connected to the skeleton component 10, and the second filler 20 is filled between the vehicle body and the skeleton component 10, filling the gap between the skeleton component 10 and the vehicle body to effectively block the airflow entering from the gap. Furthermore, there is a slit between the skeleton component 10 and the second filler 20, which makes it impossible for the second filler 20 to completely fill the gap between 10 and the vehicle body, and the edge position of the second filler 20 has a sharp corner 21. The first filler 30 is connected to the sharp corner 21, and the first filler 30 also cooperates with the vehicle body to fill the smaller slit, which can further improve the sealing between the vehicle body and the skeleton component 10, thereby improving the NVH performance of the vehicle, and has the beneficial effect of improving user experience.

[0046] It should be noted that the second filling member can be foamed plastic, EVA (ethylene-vinyl acetate copolymer), or other materials that can be used to fill the gap between the vehicle body and the sealing module. This embodiment does not impose any restrictions on this.

[0047] Optionally, in an embodiment of the present application, the first filler 30 includes a first welding portion 31 and a second welding portion 32 connected to each other; the first welding portion 31 is parallel to the thickness direction of the sharp corner 21, and is connected to the sharp corner 21 and the vehicle body, and the second welding portion 32 extends along the extension direction of the sharp corner 21 and extends to the vehicle body to form a fit with the vehicle body.

[0048] In the embodiment of the present application, the sharp corner 21 of the narrow slit cannot be inserted. When the second filler 20 is foamed, it is supported by the gap sheet metal. The second filler 20 cannot completely block the gap and there are tiny holes. As a result, the cavity cannot be completely blocked. Airflow and water can slowly enter the passenger compartment through the small holes. In order to block the tiny holes and achieve complete isolation of the cavity, such as Figure 7 And such as Figure 8As shown, at the narrow gap that the sharp corner 21 cannot reach, a first welding portion 31 and a second welding portion 32 are provided to connect with the sharp corner 21. The first welding portion 31 is parallel to the thickness direction of the sharp corner 21 (close to the height direction of the vehicle, and may also have an angle with the direction, which may be determined according to actual conditions and is not specifically limited in this embodiment), and is connected to the sharp corner 21 and the B-pillar inner panel 45. The second welding portion 32 is provided along the extension direction of the sharp corner 21. Specifically, the second welding portion 32 may extend to the welding surface of the B-pillar inner panel 45. At the same time, the second extension portion may also be connected to the first filling piece 30 applied between the B-pillar inner panel 45 and the B-pillar reinforcement plate 42. In this way, the smaller narrow gap that the second filling piece 20 cannot block can be completely blocked by the first filling piece 30. In the embodiment of the present application, the sealing of the narrow gap is improved, thereby improving the NVH performance of the vehicle, which has the beneficial effect of improving the user experience.

[0049] Furthermore, the first welding portion 31 and the second welding portion 32 are connected to each other, which has the beneficial effect of improving the connection strength of the first filling piece 30 .

[0050] Furthermore, the second welding portion 32 can have multiple welding sub-portions, and the ends of the multiple welding sub-portions connected to the first welding portion 31 are connected to each other, and the ends of the multiple welding sub-portions connected to the B-pillar 40 are dispersed with each other, which has the beneficial effect of increasing the connection area with the B-pillar 40 and improving the connection strength between the B-pillar 40.

[0051] Optionally, in an embodiment of the present application, the skeleton structure 10 includes a plurality of first reinforcements 13 and an intersecting first surface 11 and a second surface 12, wherein the first surface 11 is connected to the vehicle body; the plurality of first reinforcements 13 are arranged on the side of the first surface 11 facing the vehicle body, and the plurality of first reinforcements 13 are staggered vertically and horizontally.

[0052] In the embodiment of the present application, the first reinforcement members 13 are provided to increase the rigidity of the skeleton structure 10, thereby increasing the rigidity of the sealing module, thereby improving its pressure-bearing capacity and thereby increasing the wading depth of the vehicle. Specifically, the multiple first reinforcement members 13 may be arranged perpendicularly and staggered, or may be arranged intersecting but not perpendicularly. This embodiment does not impose any limitation on this, and any arrangement that enhances the rigidity of the first surface 11 is sufficient.

[0053] It should be noted that the first reinforcement member 13 may be a reinforcement rib or a reinforcement plate, and this embodiment does not impose any limitation on this.

[0054] Optionally, in the embodiment of the present application, the first reinforcement member 13 is a reinforcement rib.

[0055] In the embodiment of the present application, the provision of the reinforcing ribs can, on the one hand, enhance the rigidity of the skeleton structure 10 itself and thereby improve the pressure-bearing capacity of the skeleton structure 10 , while also reducing the space occupied.

[0056] Optionally, in an embodiment of the present application, the first surface 11 and the second surface 12 enclose a receiving space, and the skeleton structure 10 further includes a plurality of second reinforcement members 14, and the plurality of second reinforcement members 14 are arranged in the receiving space, and the plurality of second reinforcement members 14 are arranged at intervals along the length direction of the first surface 11; the second reinforcement members 14 are respectively connected to the first surface 11 and the second surface 12 to provide support force to the first surface 11 and the second surface 12.

[0057] In the embodiment of the present application, the first surface 11 and the second surface 12 are provided with a plurality of second reinforcement members 14. The second reinforcement members 14 connect the first surface 11 and the second surface 12 together, thereby improving the rigidity and pressure-bearing capacity of the first surface 11 and the second surface 12. Furthermore, the plurality of second reinforcement members 14 are spaced apart along the length of the first surface 11. As will be understood, these arrangements enhance the rigidity and pressure-bearing capacity of the first surface 11 along the length of the first surface 11. In summary, the embodiment of the present application improves the rigidity and pressure-bearing capacity of the skeleton structure 10.

[0058] It should be noted that the second reinforcement member 14 can be a strip reinforcement rib or a triangular rib, and this embodiment does not impose any limitation on this.

[0059] Optionally, in an embodiment of the present application, the second reinforcement 14 is a triangular rib, which includes a first rib plate, a second rib plate and a connecting piece, the connecting piece is respectively connected to the first rib plate and the second rib plate, one of the first rib plate and the second rib plate is connected to the first surface 11, and the other is connected to the second surface 12.

[0060] In an embodiment of the present application, the first rib is connected to the first surface 11, and the second rib is connected to the second surface 12, or the second rib is connected to the first surface 11, and the first rib is connected to the second surface 12. Furthermore, the connecting plate is provided to connect the first rib and the second rib, that is, an indirect connection between the first surface 11 and the second surface 12 is achieved through the connecting plate, which has the beneficial effect of enhancing the stiffness and pressure-bearing capacity of the first surface 11 and the second surface 12.

[0061] Furthermore, the contact area between the triangular rib and the first surface 11 and the second surface 12 is large, and the sheet structure of the connecting plate also has a high rigidity. Therefore, compared with the strip reinforcement rib, the triangular rib also has the beneficial effect of improving the connection stability between the first surface 11 and the second surface 12.

[0062] Optionally, in an embodiment of the present application, the skeleton structure 10 further includes a plurality of blocking members 15, and the blocking members 15 include a connecting portion and a blocking portion; the connecting portion is respectively connected to the first surface 11 and the blocking portion, or the connecting portion is respectively connected to the second surface 12 and the blocking portion; wherein, the connecting portion and the first surface 11 have a preset angle, or the connecting portion and the second surface 12 have a preset angle.

[0063] Furthermore, the blocking member 15 is connected to an end portion of the first surface 11 , and / or the blocking member 15 is connected to a side of the second surface 12 away from the first surface 11 .

[0064] In the embodiment of the present application, the blocking portions on the left and right sides of the first surface 11 are connected to the first surface 11 via a connecting portion, and the blocking portion on the side of the second surface 12 away from the first surface 11 is connected to the second surface 12 via a connecting portion. The second filler 20 is sandwiched between the first surface 11 and the blocking portion, and the second filler 20 is sandwiched between the second surface 12 and the blocking portion, wrapping the connecting portion. It should be noted that when the second filler 20 encounters an obstacle during the foaming process, it will adhere to the obstacle and expand in the direction without the obstacle. Therefore, the blocking portion can appropriately control the foaming direction of the second filler 20 so that the second filler 20 foams toward the cavity sheet metal, increasing the bonding width with the sheet metal. At the same time, after foaming, the second filler 20 will wrap the connecting portion and the blocking portion, increasing the bonding strength between the second filler 20 and the nylon frame, thereby improving the pressure-bearing capacity of the part.

[0065] It should be noted that by setting the blocking member 15 at the end of the first surface 11, the second filling member 20 can be properly controlled to foam toward the middle of the first surface 11, and by setting the blocking member 15 on the side of the second surface 12 away from the first surface 11, the second filling member 20 can be properly controlled to foam toward the middle of the second surface 12.

[0066] Optionally, in an embodiment of the present application, the skeleton structure 10 further includes a plurality of first columns 16 , which are arranged on the edge of the first surface 11 facing the vehicle body. When the second filling piece 20 is in a foamed state, the first columns 16 are enclosed in the second filling piece 20 .

[0067] In the embodiment of the present application, the edge of the first surface 11 is typically where the second filler 20 is easily separated from the workpiece of the first surface 11. The first column 16 provided at this location serves to provide an adhesive surface for the second filler 20. In practice, wrapping the first column 16 within the second filler 20 during injection molding effectively secures the second filler 20, preventing the second filler 20 from softening and falling off before reaching the foaming temperature during baking, which could result in the cavity being uninsulated.

[0068] Optionally, in an embodiment of the present application, the skeleton structure 10 further includes a plurality of second columns 17, the plurality of second columns 17 are arranged on the side of the first surface 11 facing the vehicle body, the plurality of second columns 17 are dispersedly arranged, the second columns 17 extend in a direction perpendicular to the first surface 11 and away from the first surface 11, and the second columns 17 are connected to the vehicle body.

[0069] In the embodiment of the present application, the second column 17 is fitted with the vehicle body to support the entire sealing module, leaving a suitable electrophoretic gap between the sealing module and the vehicle body, ensuring good electrophoresis of the sheet metal of the installation mechanism and preventing premature rust on the vehicle body. Furthermore, the first column 16 can also be used to provide a bonding object for the second filler 20. In actual application, when the second filler 20 is injection-molded, the second column 17 is at least partially wrapped in the second filler 20 layer, which can effectively fix the second filler 20 and has the beneficial effect of preventing the second filler 20 from softening and falling off when baking and failing to reach the foaming temperature, resulting in the inability to isolate the cavity.

[0070] It should be noted that, due to the clever design of the first column 16, the criss-crossing first reinforcement 13, the second column 17, the blocking member 15 and the second reinforcement 14 in the skeleton structure 10, the second filling member 20 can be firmly bonded to the skeleton structure 10 before and after foaming, and at the same time, the pressure-bearing capacity of the entire part after the second filling member 20 is foamed is improved, which has the effect of improving the connection performance of the vehicle body, thereby better protecting the safety of the occupants of the vehicle.

[0071] Optionally, in the embodiment of the present application, the second surface 12 is provided with a plurality of via holes 121 , and the plurality of via holes 121 are arranged at intervals along the length direction of the second surface 12 .

[0072] In the embodiment of the present application, the setting of the through hole 121 is used to ensure that the welding gun 46 can be welded to the key welding point at the lower part of the B-pillar 40. The multiple through holes 121 are arranged at intervals along the length direction of the second surface 12 to expand the welding range of the welding gun 46, thereby improving the connection performance of the vehicle body, thereby better protecting the safety of the occupants of the vehicle.

[0073] It should also be noted that the lower portion of the B-pillar 40 is one of the key locations where the upper and lower bodywork are connected, and the connection performance at this location plays an important role in protecting the occupants of the vehicle. If the entire sealing module is placed horizontally above the welding edge between the door sill 41 and the B-pillar inner panel 45 on the vehicle body, it will block the welding gun 46, resulting in the inability to weld multiple key weld points between the upper and lower bodywork at the lower portion of the B-pillar 40. Therefore, in the embodiment of the present application, the sealing module can be a special-shaped structure, with the first surface 11 mounted on the door sill 41 and located below the welding edge between the door sill 41 and the B-pillar inner panel 45, and the blocking portion located near the upper and lower welding edges of the door sill reinforcement plate 43 and the B-pillar inner panel 45. A plurality of welding gun 46 through holes 121 are designed on the second surface 12 to ensure that the welding gun 46 can weld to the key welding points at the lower portion of the B-pillar 40, thereby improving the connection performance of the vehicle body and thus better protecting the safety of the occupants of the vehicle.

[0074] Optionally, in the embodiment of the present application, the skeleton structure 10 includes a connector 18 and a skeleton electrophoresis hole 111 . The connector 18 is provided on the side of the first surface 11 facing the vehicle body, and the skeleton electrophoresis hole 111 is opened on the first surface 11 .

[0075] In this embodiment of the present application, the provision of the skeleton electrophoresis holes 111 ensures smooth flow of electrophoretic fluid within the vehicle body cavity, ensuring that the thickness of the sheet metal electrophoresis film within the cavity meets the required requirements and preventing premature corrosion of parts. Specifically, the number of skeleton electrophoresis holes 111 can be four. The provision of the connector 18 is used to secure the sealing module to the door sill 41.

[0076] It should be noted that the skeleton electrophoresis hole 111 may include two oblong electrophoresis holes with a size of 8×20 mm, one circular electrophoresis hole with a diameter of φ13 mm and one superior arc electrophoresis hole with a diameter of 13 mm. The specific size can be determined according to actual conditions, and this embodiment does not impose any restrictions on this.

[0077] Optionally, in an embodiment of the present application, the second filling piece 20 includes four through holes 22, and the through holes 22 are arranged corresponding to the connecting piece 18 or the skeleton electrophoresis hole 111; when the second filling piece 20 is in a foaming state, the through holes 22 cover the connecting piece 18 or the electrophoresis hole.

[0078] In the embodiment of the present application, the through hole 22 is provided to realize electrophoresis. At the same time, the second filler 20 can seal its own electrophoresis hole tightly after baking and foaming, thereby preventing airflow and water from entering the passenger compartment through the skeleton electrophoresis hole 111.

[0079] Furthermore, since it is not possible to weld the left and right ends of the lower area of the B-pillar 40 when the upper and lower bodies are joined together, welding holes are usually opened on the welding edge of the rocker inner panel 44 for welding to connect the upper and lower bodies. Due to the high heat generated by welding, the first filler 30 applied to the welding area or the first filler 30 is usually burned off, thus failing to provide a seal. Furthermore, the above-mentioned area is usually only coated with weld sealant (such as Figure 8 As shown), the weld sealant can only seal the welding hole and the gap between the lap joint of the door sill inner plate 44 and the B-pillar inner plate 45; while the lap joint of the door sill reinforcement plate 43 and the B-pillar inner plate 45 ( Figure 8 The gap (marked by the dotted circle) is located within the cavity of the B-pillar 40, preventing the application of glue. Consequently, there are air and water leaks along the overlapping edges. To address this issue, the sealing module is designed with the second filler 20 positioned near the cut edge of the overlapping edge between the B-pillar inner panel 45 and the rocker reinforcement panel 43. This allows the second filler 20 to completely cover the cut edge during the baking and foaming process, achieving a seal.

[0080] Optionally, in the embodiment of the present application, the first filling member 30 is welding glue.

[0081] In the embodiments of the present application, the spot welding adhesive can be used for bonding and potting metal and non-metal materials, as well as for bonding and potting metal materials with each other. The spot welding adhesive offers advantages such as high connection strength, good sealing, uniform stress distribution, excellent fatigue resistance, and a lightweight structure. It effectively seals the sealing module and the vehicle body, preventing gaps between the two that could cause excessive noise and negatively impact the user experience.

[0082] Optionally, in the embodiment of the present application, the second filling piece 20 is foamed rubber.

[0083] In the embodiment of the present application, the foamed adhesive foam after foaming and curing has multiple effects such as filling, bonding, sealing, heat insulation, and sound absorption. It can be used for sealing and plugging leaks, fixing and bonding, and sound insulation. It is suitable for the embodiment of the present application to avoid the problem of noise caused by gaps between the skeleton component 10 and the vehicle body.

[0084] Optionally, in an embodiment of the present application, a vehicle body is further provided, including a B-pillar 40 ; a door sill 41 ; and the sealing module as described above, wherein the sealing module is respectively connected to the B-pillar 40 and the door sill 41 .
