[0002] As a vital means of transportation in modern life, the comfort and safety of automobiles are of paramount importance. Sealing performance, a crucial performance indicator for vehicles, ensures that the passenger compartment and other critical areas are protected from rainwater infiltration and corrosion, thus guaranteeing driving safety. These critical areas are known as the dry zone. However, inevitably, some panels on the vehicle body have openings located at the boundary between the dry and wet zones. To ensure the sealing of these openings, sealant is typically used to plug them. Furthermore, for wiring harnesses passing through holes in the panels, gaps between the harness and the hole structure can easily transmit vibrations into the passenger compartment, generating noise and compromising comfort.

[0003] To ensure sealing, sealing components can be used to seal the hole structure. However, existing sealing components are inconvenient to install and cannot be disassembled after installation, making maintenance difficult.

[0004] Therefore, it is necessary to provide a sealing component that can ensure stable sealing while also facilitating disassembly and maintenance. Utility Model Content

[0030] To enable those skilled in the art to better understand the technical solutions of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] This application provides a sealing component 10 and a vehicle. The sheet metal parts 20 of the vehicle are provided with hole structures 201 such as wiring harness holes, pipe holes, and reserved mounting holes. If the sealing performance of these hole structures 201 is not good, it is easy to cause water leakage or transmit noise to the cab, which may lead to vehicle malfunction or affect the NVH (Noise, Vibration, Harshness) performance of the whole vehicle. The sealing component 10 provided in this embodiment can effectively seal the hole structures 201 of the sheet metal parts 20, and prevent water leakage or noise generation at the hole structures 201 of the sheet metal parts 20.

[0032] like Figure 1 and Figure 2As shown, the sealing assembly 10 includes a skeleton 1 and a rubber plug 2. The skeleton 1 is a rigid skeleton 1 used to fix it to the plate 20. It can be a metal skeleton, a plastic skeleton, etc. The skeleton 1 is preferably made of a material with a Shore hardness value in the range of 45-55 to facilitate disassembly and assembly. The skeleton 1 includes a support part 11 and a first snap-fit ​​part 12. The first snap-fit ​​part 12 is used to snap-fit ​​and fix it to the plate 20. The rubber plug 2 is a flexible rubber plug 2. It can preferably be a rubber part such as ethylene propylene diene monomer (EPDM). The rubber plug 2 is connected to the support part 11. The skeleton 1 can be snap-fitted and fixed to the plate 20 through the first snap-fit ​​part 12. The rubber plug 2 can fit against the plate 20 along the circumference of the hole structure 201 to ensure the sealing of the hole structure 201.

[0033] The plate 20 has a hole structure 201. One side surface of the plate 20 forms a limiting surface 202, and the other side surface forms a sealing surface 203. During installation, the first snap-fit ​​part 12 can be inserted into the hole structure 201 and engage with the limiting surface 202 at the edge of the hole structure 201, restricting the skeleton 1 from moving relative to the plate 20 towards the rubber plug 2 and disengaging. The rubber plug 2 can abut against the sealing surface 203 of the plate 20. Through the rubber plug 2 and the first snap-fit ​​part 12, the movement between the sealing assembly 10 and the plate 20 along the axial direction of the hole structure 201 can be restricted, thereby realizing the snap-fit ​​fixation between the skeleton 1 and the plate 20. In the fixed state, the rubber plug 2 can adhere to the sealing surface 203 along the circumference of the hole structure 201 to achieve the sealing effect of the hole structure 201.

[0034] The frame 1 also includes an operating part 14, which is connected to the first snap-fit ​​part 12. The operating part 14 can act on the first snap-fit ​​part 12 to move the first snap-fit ​​part 12 to the unlocked state. In the unlocked state, the snap-fit ​​between the first snap-fit ​​part 12 and the plate 20 is released, and the sealing assembly 10 can be separated from the plate 20, thereby realizing the disassembly of the sealing assembly 10.

[0035] In other words, when it is necessary to disassemble the sealing assembly 10, the operator can use the operating part 14 to act on the first locking part 12, causing the first locking part 12 to move to the unlocked state, thereby removing the sealing assembly 10. Furthermore, during installation, the operating part 14 can also be used to act on the first locking part 12 to move it to the unlocked state. After installation, the operation on the operating part 14 can be removed, causing the first locking part 12 to return to the locking state, i.e., the first locking part 12 is engaged with the plate 20. In this way, even if the frame has high rigidity, installation can be convenient.

[0036] The sealing assembly 10 provided in this embodiment uses a frame 1 to fix the plate 20 to ensure installation stability and a rubber plug 2 to ensure sealing. This configuration ensures that the sealing assembly 10 can achieve a stable sealing effect at the hole structure 201 of the plate 20. An operator can use the operating part 14 to act on the first snap-fit ​​part 12 to release the snap-fit ​​between the frame 1 and the plate 20, facilitating the disassembly of the sealing assembly 10 and enabling convenient maintenance and replacement operations with good flexibility.

[0037] like Figure 2 , Figure 4 and Figure 5 As shown, the first snap-fit ​​portion 12 is provided with a first groove 121. The groove opening of the first groove 121 is provided on one side facing the rubber plug 2. The two opposite wall portions of the first groove 121 are respectively formed as a first wall portion 1211 and a second wall portion 1212. The first wall portion 1211 is connected to the bracket portion 11, and the outer wall surface of the second wall portion 1212 is provided with a first snap-fit ​​protrusion 122. During installation, when the first snap-fit ​​part 12 passes through the hole structure 201, it is squeezed, causing the first groove 121 to deform. After the first snap-fit ​​protrusion 122 passes through the hole structure 201, the first groove 121 can return to its original shape, allowing the first snap-fit ​​protrusion 122 to snap onto the limiting surface 202 of the plate 20, restricting the movement of the sealing assembly 10 relative to the plate 20 towards the rubber plug 2. At the same time, the rubber plug 2 can fit against the sealing surface 203 of the plate 20, restricting the movement of the sealing assembly 10 relative to the plate 20 towards the skeleton 1, thereby achieving snap-fit ​​fixation between the sealing assembly 10 and the plate 20, facilitating installation and ensuring snap-fit ​​stability. The first groove 121 facilitates the elastic deformation of the first wall part 1211 and the second wall part 1212, reducing the force during installation.

[0038] Of course, in this embodiment, there are no restrictions on the snap-fit ​​between the frame 1 and the plate 20. The frame 1 can be provided with snap-fit ​​protrusions and the snap-fit ​​is achieved by the snap-fit ​​protrusions and the rubber plugs 2 respectively pressing against the plate 20 from both sides. Alternatively, the frame 1 can be provided with snap-fit ​​grooves and the snap-fit ​​is achieved by the snap-fit ​​grooves engaging with the plate 20 along the edge of the hole structure 201. The snap-fit ​​is achieved by the engagement of the snap-fit ​​protrusions and the rubber plugs 2, which simplifies the structure of the frame 1.

[0039] The opening end of the second wall portion 1212 extends toward the side of the rubber plug 2, forming the aforementioned operating part 14. That is, when it is necessary to disassemble the sealing assembly 10, the operator moves the extension structure of the second wall portion 1212 of the first groove 121, causing the first groove 121 to deform. The second wall portion 1212 drives the first snap-fit ​​protrusion 122 to move toward the side of the first wall portion 1211 until the first snap-fit ​​protrusion 122 disengages from the plate 20. Due to the setting of the first groove 121, it is relatively easy for the first wall portion 1211 and the second wall portion 1212 to deform, thereby reducing the force required to disassemble the sealing assembly 10 by operating the operating part 14.

[0040] The first wall portion 1211 is connected to the bracket portion 11 to form a fixed wall portion, and the second wall portion 1212 extends to form an operating portion 14. The second wall portion 1212 is equivalent to a movable wall portion. The operating portion 14 can act on the movable wall portion to move it relative to the fixed wall portion, change the position of the first snap-fit ​​protrusion 122, and switch between the snap-fit ​​state and the unlocked state.

[0041] Of course, in this embodiment, the specific structure of the operating part 14 is not limited. For example, the operating part 14 can move the entire first snap-fit ​​part 12 to release the snap-fit ​​between it and the plate 20, or the operating part 14 can rotate the first snap-fit ​​part 12 and drive the first snap-fit ​​protrusion 122 to rotate until it is disengaged from the plate 20. In this embodiment, the operating part 14 is formed by the extension structure of the second wall part 1212 of the first groove 121. The deformation of the second wall part 1212 drives the first snap-fit ​​protrusion 122 to disengage from the plate 20, which simplifies the structural setting of the first snap-fit ​​part 12 and the operating part 14, simplifies the molding process, and reduces costs.

[0042] The frame 1 is provided with two sets of first latching parts 12. These two sets of first latching parts 12 are respectively located on opposite sides of the support part 11. Each set of first latching parts 12 corresponds to an operating part 14. When disassembling, the operating part 14 can be used to move the first latching part 12 to the side of the other first latching part 12. The two operating parts 14 can be moved closer to each other to unlock the frame. The operation is relatively convenient.

[0043] Of course, in this embodiment, there is no limit to the number of the first snap-fit ​​parts 12. There can be one, three or more. The arrangement of two oppositely arranged first snap-fit ​​parts 12 can ensure the installation stability between the parts and the plate 20, while also simplifying the overall structure and facilitating disassembly and assembly.

[0044] Or, such as Figure 2 , Figure 4 and Figure 5As shown, in this embodiment, the frame 1 further includes a second latching portion 13, which, along with the first latching portion 12, is respectively located on opposite sides of the support portion 11. Both the first latching portion 12 and the second latching portion 13 are used to latch with the plate 20. The first latching portion 12 is an unlockable latching portion, and can be moved towards the second latching portion 13 by the operation portion 14 to achieve an unlocked state. The second latching portion 12 is not connected to the operation portion 14. In this case, the frame 1 only has one operation portion 14, making the overall structure simpler.

[0045] like Figure 4 As shown, the second snap-fit ​​portion 13 is further provided with a second groove 131 on the side facing the rubber plug 2. The side wall of the second groove 131 facing the first snap-fit ​​portion 12 is connected to the bracket portion 11. The outer wall surface of the side wall of the second groove 131 away from the first snap-fit ​​portion 12 is provided with a second snap-fit ​​protrusion 133. The provision of the second groove 131 allows the second snap-fit ​​portion 13 to be squeezed and deformed during installation when it passes through the hole structure 201. After the second snap-fit ​​protrusion 133 passes through the hole structure 201, the second groove 131 can return to its original shape, allowing the second snap-fit ​​protrusion 133 to snap onto the limiting surface 202 of the plate 20, which facilitates installation and ensures snap-fit ​​stability.

[0046] In this embodiment, there are no restrictions on the cross-section of the first groove 121 and the second groove 131; they can be either U-shaped or V-shaped.

[0047] Furthermore, taking the first latching portion 12 as an example, the first latching portion 12 can be a block structure with a first groove 121, or the first latching portion 12 can be a structure including two connectors, the bottoms of which are connected to form a U-shaped structure or a V-shaped structure with the first groove 121, and no specific limitation is made here. The setting of the second latching portion 13 can refer to the first latching portion 12, and will not be described again here.

[0048] In this embodiment, the structure of the second latching portion 13 can also be as follows: Figure 5 As shown, it includes a connecting portion 132 connected to the support portion 11. One end of the connecting portion 132 is connected to the support portion 11. A second snap-fit ​​protrusion 133 is provided on the side of the connecting portion 132 away from the first snap-fit ​​portion 12. The connecting portion 132 and the second snap-fit ​​protrusion 133 of the second snap-fit ​​portion 13 can be formed as follows: Figure 5 The L-shaped structure shown can also be formed into a T-shaped structure. This arrangement simplifies the overall structure of the second snap-fit ​​part 13.

[0049] The rubber stopper 2 also arches outwards to the side away from the frame 1 to form an arched portion 21. This arched portion 21 covers the operating part 14 to prevent the operating part 14 from leaking out and to ensure sealing. Of course, in this embodiment, the rubber stopper 2 may not have an arched portion 21. The rubber stopper 2 can directly cover the frame 1 (including the operating part 14). Since the rubber stopper 2 has a certain elasticity, the operator can directly apply the rubber stopper 2 to the position corresponding to the operating part 14 to release the locking effect between the first locking part 12 and the plate 20. Alternatively, the rubber stopper 2 can cover the frame 1, and the operating part 14 can pass through the rubber stopper 2. The arched portion 21 makes it easy for the operator to quickly identify the position of the operating part 14 and can also ensure the sealing between the rubber stopper 2 and the frame 1.

[0050] The sealing component 10 provided in this embodiment can be as follows: Figure 1 and Figure 2 As shown, it is used to seal the entire hole structure 201. At this time, after the skeleton 1 is fixed to the plate 20, the rubber plug 2 can cover the entire hole structure 201, or it can be as follows: Figures 3-5 As shown, after the pipeline 30 passes through the hole structure 201, there is a gap between the pipeline 30 and the hole structure 201. At this time, the rubber plug 2 can seal the gap between the pipeline 30 and the hole structure 201.

[0051] When the rubber plug 2 is used to seal the gap between the pipeline 30 and the hole structure 201, such as Figures 3-5 As shown, the rubber stopper 2 has a sleeve 22 on the side away from the skeleton 1. The sleeve 22 also has a constriction section 221. The cross-sectional area of ​​the constriction section 221 is smaller than the cross-sectional area of ​​the sleeve 22 on the side facing the skeleton 1. The cross-sectional shape and size of the constriction section 221 can be set according to the cross-sectional shape and size of the pipeline 30. The inner wall surface of the constriction section 221 forms a pipeline contact surface. During installation, the pipeline 30 passes through the sleeve 22, and the pipeline contact surface of the constriction section 221 can fit against the outer wall of the pipeline 30 to achieve a seal. The location of the constriction section 221 is not limited; it can be the end of the sleeve 22 or any section along the length of the sleeve 22.

[0052] Of course, in this embodiment, the sleeve 22 may not have a constriction section 221. The gap between the sleeve 22 and the pipeline 30 can be sealed and fixed by filling with sealant or cement. The inner wall of the constriction section 221 is attached to the outer wall of the pipeline 30 to achieve sealing and fixation, which can simplify the overall structure and simplify the installation operation.

[0053] like Figure 2 , Figure 4 and Figure 5As shown, the rubber plug 2 has an annular sealing protrusion 23 along the outer periphery of the bracket portion 11. When the skeleton 1 and the plate 20 are in a snap-fit ​​fixed state, the annular sealing protrusion 23 fits against the plate 20 in the circumferential direction and is under slight pressure. The annular sealing protrusion 23 can abut against and fit stably against the sealing surface 203 of the plate 20 in the circumferential direction, so as to achieve the fit between the hole structure 201 and the sealing surface 203 of the plate 20 in the circumferential direction, and ensure the sealing performance.

[0054] Of course, in this embodiment, the end face of the rubber plug 2 can also be abutted against the sealing surface 203 of the plate 20 to ensure sealing. The annular sealing protrusion 23 is more likely to undergo micro-deformation under the abutment action, which can further ensure the stability of the fit and the sealing performance.

[0055] like Figure 2 , Figure 4 and Figure 5 As shown, the annular sealing protrusion 23 has a gradually expanding structure from the end of the rubber stopper 2 to the side away from the rubber stopper 2. That is to say, the annular sealing protrusion 23 is inclined outward towards the side facing the skeleton 1. Here, "outward" refers to the side outside the area formed by the annular sealing protrusion 23 along the circumference. This setting can provide guidance for the deformation of the annular sealing protrusion 23 during the extrusion process. When the skeleton 1 is fixed in place with the plate 20, the annular sealing protrusion 23 is in a slightly compressed state. Since the side of the annular sealing protrusion 23 facing the skeleton 1 is attached to the sealing surface 203 and slides outward, it ensures that the annular sealing protrusion 23 can achieve abutment and contact with the sealing surface 203 along the circumference. It can also increase the contact area between the annular sealing protrusion 23 and the sealing surface 203, thus ensuring the sealing performance.

[0056] In this embodiment, there are no restrictions on the connection method between the rubber stopper 2 and the bracket portion 11. The rubber stopper 2 and the bracket portion 11 can be connected by snap-fit ​​or by adhesive bonding. Alternatively, the rubber stopper 2 and the bracket portion 11 can be integrally vulcanized. Snap-fit ​​connection between the rubber stopper 2 and the bracket portion 11 facilitates disassembly and assembly, while adhesive bonding simplifies the molding process.

[0057] The support portion 11 has an annular structure. The inner circumferential wall of the end of the rubber plug 2 facing the frame 1 has a groove 24 along the circumferential direction. The circumferential edge of the support portion 11 is engaged in the groove 24, making installation relatively convenient. Alternatively, the outer circumferential wall of the support portion 11 can have a groove along the circumferential direction, and the inner circumferential wall of the end of the rubber plug 2 facing the frame 1 can have a protrusion along the circumferential direction, which can be engaged in the groove. When the rubber plug 2 has a groove 24 and the circumferential edge of the support portion 11 is engaged in the groove 24, the structure of the sealing assembly 10 can be simplified while ensuring that the rubber plug 2 covers the frame 1 and seals the hole structure 201.

[0058] The bracket portion 11 can be entirely snapped into the slot 24, or only its circumferential edge can be snapped into the slot 24. The bracket portion 11 can also be a plate-like structure with through holes that are connected to the hole structure 201. The first snap-fit ​​portion 12 and the second snap-fit ​​portion 13 can be entirely located within the annular structure or the through holes, or the annular structure can also have mounting holes in its circumferential direction for mounting the first snap-fit ​​portion 12 or the second snap-fit ​​portion 13.

[0059] For example Figure 1 and Figure 3 As shown, the surface of the rubber stopper 2 is also provided with an indicator part 25. Specifically, it can be provided with a structure such as an indicator arrow or text by setting a protrusion, scribing, or printing coating. The indicator part 25 is used to indicate the installation direction, so as to facilitate the operator to install quickly.
