Description

Technical Field

[0001] This application relates to the field of vehicle technology, specifically to a sealing assembly and a vehicle. Background Technology

[0002] As an important means of transportation in modern life, the comfort and safety of automobiles are of utmost importance. Sealing performance, as one of the important performance indicators of automobiles, ensures that the cabin and other important areas are not penetrated and corroded by rainwater, thus ensuring driving safety. These important areas are called dry areas. However, inevitably, there will be some openings in the body panels that are located at the boundary between the dry and wet areas. In order to ensure the sealing of the openings in the panels, sealant is usually used to seal the openings.

[0003] For example, the LiDAR wiring harness in a vehicle passes through the hole structure of the vehicle's sheet metal and connects the dry and wet areas. It needs to be sealed by a sealing component in the hole structure of the sheet metal to achieve a sealing and waterproofing effect. However, traditional sealant plugs cannot achieve a good sealing effect.

[0004] Therefore, ensuring the sealing effect at the holes in the plate is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] The purpose of this application is to provide a sealing assembly and a vehicle that can seal a plate with a perforated structure, ensure the force on the annular protrusion in the installation state through the skeleton, and effectively ensure the reliability and stability of the seal by having at least two annular sealing edges adhere to the surface of the plate.

[0006] To solve the above-mentioned technical problems, this application provides a sealing assembly, including a sealing part and a skeleton. The top of the skeleton is connected to the sealing part, and the skeleton is provided with a plate fixing part. The sealing part is also provided with at least two spaced annular protrusions on one end face facing the skeleton, and the annular protrusions are arranged circumferentially along the skeleton.

[0007] Optionally, the annular protrusion has a gradually expanding structure from its root toward one side of the skeleton;

[0008] And / or, the height of the annular protrusion located on the inner side is less than the height of the annular protrusion located on the outer side.

[0009] Optionally, the side face of the skeleton facing the sealing part is a planar structure.

[0010] Optionally, the plate fixing part is provided with a limiting step, and the step surface of the limiting step forms the plate abutment surface.

[0011] Optionally, the bottom of the sealing part is provided with a fixing groove, the inner wall of the fixing groove is provided with a slot along the circumference, and the edge of the skeleton forms a snap-fit ​​protrusion and snaps into the slot;

[0012] The width of the snap-fit ​​protrusion is not less than 3.5 mm, and / or the thickness of the snap-fit ​​protrusion is in the range of 1 mm to 1.5 mm.

[0013] Optionally, the thickness of the sealing part is not less than 4.5 mm.

[0014] Optionally, the sealing part has a positioning protrusion on one end face facing the skeleton, and the skeleton has a positioning notch or positioning groove that matches the positioning protrusion.

[0015] Alternatively, the sealing part may have a positioning notch or positioning groove on one end face facing the skeleton, and the skeleton may have a positioning protrusion that matches the positioning notch or positioning groove.

[0016] Optionally, a sleeve is also connected to the end face of the sealing part away from the annular protrusion, the end of the sleeve is connected to the sealing part, and the outer peripheral wall of the sleeve is separated from the peripheral side wall of the sealing part.

[0017] Optionally, the angle between the axis of the sleeve and the end face of the sealing part away from the annular protrusion is in the range of 10°-90°.

[0018] This application also provides a vehicle including a plate and a sealing assembly as described above. The plate has a hole structure, and the skeleton of the sealing assembly is fixed to the plate by a plate fixing part. The sealing part can cover the hole structure, and the annular protrusion can conform to the surface of the plate along the circumference of the hole structure.

[0019] The sealing assembly and vehicle provided in this application have the following technical advantages compared to the prior art:

[0020] The annular protrusion is arranged along the circumference of the skeleton. When the skeleton is fixed to the plate by the plate fixing part, the annular protrusion is in contact with the plate surface along the circumference of the hole structure and is in a state of compression deformation, which ensures the sealing reliability between the sealing assembly and the plate along the circumference of the hole structure.

[0021] By fixing the rigid frame to the plate, it can be ensured that the annular protrusion is in a compressed state during installation, and the compressive force on the annular protrusion is stable, thereby ensuring the sealing effect of the sealing component on the hole structure.

[0022] By using annular protrusions to adhere to the surface of the plate, compared to directly adhering the bottom end face of the sealing part to the plate surface, this method ensures that the annular protrusions adhere and seal the plate surface at all circumferential positions while reducing the adhesion force, thus facilitating adhesion stability and reliability. Furthermore, the bottom end face of the sealing part has at least two annular protrusions, each providing at least two layers of sealing from the outside in, further ensuring the reliability of the seal.

[0031] 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.

[0032] This application provides a sealing component and a vehicle. The sheet metal parts of the vehicle have hole structures such as wiring harness holes, pipe holes, and reserved mounting holes. If the sealing performance of these hole structures is not good, it is easy to cause water leakage or noise transmission to the cab, which may lead to vehicle malfunction or affect the NVH (Noise, Vibration, Harshness) performance of the whole vehicle. The sealing component provided in this embodiment can effectively seal the hole structures of the sheet metal parts, avoiding water leakage or noise generation at the hole structures of the sheet metal parts.

[0033] like Figure 1 and Figure 2 As shown, the sealing assembly includes a sealing part 1 and a frame 2. The frame 2 is provided with a plate fixing part 23 for fixing to the plate. The sealing part 1 is connected to the top of the frame 2. When the frame 2 is fixed to the plate through the plate fixing part 23, the sealing part 1 can seal the hole structure to ensure the sealing performance at the hole structure.

[0034] The end face of the sealing part 1 facing the frame 2 is the bottom end face of the sealing part 1. Correspondingly, the end face of the sealing part 1 opposite to the bottom end face is the top end face. The bottom end face of the sealing part 1 is provided with an annular protrusion 11. The annular protrusion 11 is arranged along the circumference of the frame 2. When the frame 2 is fixed to the plate by the plate fixing part 23, the annular protrusion 11 is in contact with the plate surface along the circumference of the hole structure and is in a state of compression deformation, so as to ensure the sealing reliability between the sealing assembly and the plate along the circumference of the hole structure.

[0035] By attaching the annular protrusion 11 to the surface of the plate, compared with the solution of attaching the bottom end face of the sealing part 1 to the surface of the plate directly, it is possible to ensure that the annular protrusion 11 can be attached to the surface of the plate at all positions along the circumference while reducing the bonding force, thereby making it easier to ensure bonding stability and reliability.

[0036] The skeleton 2 is a rigid skeleton used to fix it to the plate. It can be a PA66-GF15 skeleton, or a metal skeleton, plastic skeleton, etc. The hardness of the skeleton 2 should be greater than that of the sealing part 1. The material hardness of the skeleton 2 can be adjusted according to the interface conditions matched with the skeleton 2. The sealing part 1 (including the annular protrusion 11, etc.) is a flexible sealing part such as a rubber part. When the skeleton 2 is fixed to the plate, the sealing part 1 can fit against the plate along the circumference of the hole structure to ensure the sealing of the hole structure.

[0037] By fixing the rigid frame 2 to the plate, the annular protrusion 11 is kept in a compressed state during installation, and the compressive force on the annular protrusion 11 is stable, thereby ensuring the sealing effect of the sealing assembly on the hole structure. In this embodiment, the specific structure of the plate fixing part 23 is not limited, such as... Figure 3 and Figure 4As shown, the plate fixing part 23 is provided with a limiting step, and the step surface of the limiting step forms the plate abutment surface 231. The plate abutment surface 231 is provided facing the sealing part 1. During installation, the plate fixing part 23 deforms and can return to its original shape after passing through the hole structure. At this time, the plate abutment surface 231 can abut against the side surface of the plate away from the sealing part 1 (i.e., the lower surface) and restrict the sealing assembly from moving relative to the plate towards the sealing part 1. At the same time, the annular protrusion 11 of the sealing part 1 can fit against the upper surface of the plate and restrict the sealing assembly from moving relative to the plate away from the sealing part 1. That is, the sealing assembly and the plate are axially limited along the hole structure, thereby realizing the fixing of the sealing assembly and the plate.

[0038] Alternatively, the plate fixing part 23 can be provided with a snap-fit ​​groove. During installation, after the plate fixing part 23 undergoes elastic deformation and inserts into the hole structure, it can return to its original shape, so that the plate is located in the snap-fit ​​groove along the edge of the hole structure, thereby fixing the sealing component to the plate. Alternatively, the plate fixing part 23 can be provided with an external thread on the outer peripheral wall of the frame 2, and the inner peripheral wall of the hole structure is provided with an internal thread. The plate fixing part 23 is fixed to the plate through threaded engagement, which can ensure the fixing stability between the frame 2 and the plate, ensure the force on the annular protrusion 11, and thus ensure the sealing stability.

[0039] The plate fixing part 23 simplifies its structure and facilitates installation by providing a limiting step and forming a plate abutment surface 231 on the step surface of the limiting step for abutment with the plate. Furthermore, the plate abutment surface 231 formed by the step surface of the limiting step not only restricts axial movement along the hole structure by abutting with the plate, but also restricts swaying along the radial direction of the hole structure by the vertical limiting surface 232 of the limiting step, resulting in good stability.

[0040] The number of plate fixing parts 23 is not limited. It can be one or two or more arranged at intervals along the circumference of the skeleton 2. The specific arrangement can be determined according to the actual situation.

[0041] And, as Figure 2 As shown, the bottom end face of the sealing part 1 is provided with two annular protrusions 11. The two annular protrusions 11 provide a double sealing effect from the inner and outer sides to further ensure the sealing stability. Here, "inner" refers to the side facing the central axis of the annular protrusion 11, and "outer" refers to the side away from the central axis of the annular protrusion 11.

[0042] In this embodiment, the number of annular protrusions 11 is not limited; there can be two, three, four, or more, depending on the actual situation. With at least two layers of sealing, the sealing performance at the hole structure of the plate can be effectively guaranteed.

[0043] like Figure 2 As shown, the annular protrusion 11 has a gradually expanding structure from its root towards one side of the frame 2. The base of the annular protrusion 11 is connected to the bottom end face of the sealing part 1. That is to say, the annular protrusion 11 has a gradually expanding horn structure. The small end of the horn structure is set towards the bottom end face of the sealing part 1. This setting can guide the deformation of the annular protrusion 11 during the installation and compression process. When the frame 2 is fixed to the plate, the annular protrusion 11 is in a compressed state. The side of the annular protrusion 11 away from the sealing part 1 is attached to the surface of the plate and slides outward. This ensures that the annular protrusion 11 can achieve abutment and fit with the surface of the plate in the circumferential direction. It can also increase the contact area between the annular protrusion 11 and the surface of the plate and ensure the sealing performance.

[0044] like Figure 2 As shown, each annular protrusion 11 has a gradually expanding structure. Of course, only the outermost annular protrusion 11 can have a gradually expanding structure. When each annular protrusion 11 is set to a gradually expanding structure, the sealing effect of all annular protrusions 11 can be ensured.

[0045] In this embodiment, the angle between the side wall of the annular protrusion 11 and its central axis is not limited, such as within the range of 30°-60°, specifically 30°, 45°, 60°, etc., to ensure that the annular protrusion 11 provides a guiding function during the compression process, while also ensuring the sealing performance in the installed state.

[0046] like Figure 2 As shown, the height of the outer annular protrusion 11 is higher than that of the inner annular protrusion 11. This design ensures sealing stability while facilitating installation, reducing effort, and lowering the strength requirements for fixing the frame 2 to the plate. The specific height of the annular protrusion 11 is not critical and can be set according to actual conditions.

[0047] like Figure 3 and Figure 4As shown, the top end face 21 of the frame is a planar structure, and the planar structure is parallel to the bottom end face of the sealing part 1. The top end face 21 of the frame can be provided with a groove structure. Of course, there are no restrictions on the structure of the top end face 21 of the frame. For example, it can also be set as a sloping structure. When the top end face 21 of the frame is set as a planar structure, the thickness requirement of the sealing part 1 can be reduced while ensuring the installation stability with the sealing part 1. This is beneficial to reduce the overall size of the sealing assembly, reduce the overall weight, reduce the cost, and reduce the requirements for installation space.

[0048] like Figure 2 As shown, the bottom end face of the sealing part 1 is also provided with a fixing groove. One side end of the frame 2 is engaged in the fixing groove. Specifically, the inner wall of the fixing groove is provided with a groove 13 along the circumference. The top edge of the frame 2 extends outward to form a snap-fit ​​protrusion 22, which is engaged in the groove 13. The width W of the snap-fit ​​protrusion 22 is not less than 3.5mm, such as 3.5mm, 4mm, 5mm, 6mm, etc. Compared with the scheme of setting the width of the snap-fit ​​protrusion 22 to less than 3.5mm, such as 3mm or 2mm, it can more effectively ensure the snap-fit ​​stability between the frame 2 and the sealing part 1.

[0049] The thickness of the snap-fit ​​protrusion 22 is preferably set in the range of 1mm-1.5mm, such as 1mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm, 1.5mm, etc. Compared with the scheme of setting the thickness of the snap-fit ​​protrusion 22 to 0.8mm, 1mm, 1.6mm, 1.8mm, etc., it can ensure the stability of the fit between the snap-fit ​​protrusion 22 and the slot 13, and also avoid the situation that the thickness of the sealing part 1 is too large due to the large thickness of the snap-fit ​​protrusion 22. This is conducive to the overall miniaturization of the sealing assembly and reduces the requirements for installation space.

[0050] Of course, in this embodiment, the connection method between the frame 2 and the sealing part 1 is not limited. For example, the end of the frame 2 may be provided with a groove 13 and the sealing part 1 may be provided with a snap-fit ​​protrusion 22. Alternatively, the top end face 21 of the frame and the bottom end face of the sealing part 1 may be fixed by adhesive bonding. The sealing part 1 is provided with a groove 13, and the top edge of the frame 2 is snapped into the groove 13, which can ensure the snap-fit ​​stability and facilitate the installation operation between the two.

[0051] The thickness of the sealing part 1 is not less than 4.5mm. The thickness of the sealing part 1 refers to the thickness between the top end face and the bottom end face (excluding the annular protrusion 11). Specifically, it can be 4.5mm, 5mm, 6mm, 7mm, etc. Compared with setting the thickness of the sealing part 1 to less than 4.5mm, such as 4mm, 3mm, etc., it can ensure the structural strength of the sealing part 1, thereby ensuring the connection stability between the sealing part 1 and the skeleton 2.

[0052] In this embodiment, the frame 2 is a one-piece structure. Of course, the frame 2 can also be set as a split structure. Setting the frame 2 as a one-piece structure simplifies the overall structure and facilitates installation. In this embodiment, there are no restrictions on the structure and molding process of the frame 2, which can be determined according to the specific circumstances.

[0053] like Figure 5 As shown, the top of the frame 2 is also provided with a positioning notch 24. Correspondingly, the sealing part 1 is also provided with a positioning protrusion (not shown in the figure). During installation, the positioning protrusion is located inside the positioning notch 24, which snaps the sealing part 1 and the frame 2 together and fixes them in place. The positioning notch 24 and the positioning protrusion form a mutually compatible positioning structure, which can ensure the structural stability of the sealing assembly and prevent relative rotation between the frame 2 and the sealing part 1. The number of positioning notches 24 can be as follows: Figure 5 The two shown can also be one or more.

[0054] Of course, the skeleton 2 can also be provided with a positioning groove, which forms a mutually compatible positioning structure with the positioning protrusion provided on the sealing part 1. Alternatively, the sealing part 1 can be provided with a positioning groove or positioning notch, and the skeleton 2 can be provided with a positioning protrusion.

[0055] The sealing component provided in this embodiment can be used to seal the entire hole structure. In this case, after the skeleton 2 is fixed to the plate, the sealing part 1 can cover the entire hole structure. This structure is suitable for hole structures such as reserved holes, where no wires or pipes are installed in the hole structure. Alternatively, it can be used when a pipe passes through the hole structure and there is a gap between the pipe and the hole structure. In this case, the sealing part 1 can seal the gap between the pipe and the hole structure.

[0056] When the sealing part 1 is used to seal the gap between the pipeline and the hole structure, a sleeve 12 is provided on the side of the sealing part 1 away from the skeleton 2. The sleeve 12 is fitted over the pipeline and fits against the outer wall of the pipeline to achieve a seal. The cross-sectional shape and size of the sleeve 12 can be set according to the cross-sectional shape and size of the pipeline. The inner wall surface of the sleeve 12 forms the pipeline fitting surface. During installation, the pipeline passes through the sleeve 12, and the pipeline fitting surface of the sleeve 12 can fit against the outer wall of the pipeline to achieve a seal. To further ensure the fitting and sealing between the sleeve 12 and the pipeline, the sleeve 12 can also be provided with a tapered section. The cross-sectional area of ​​the tapered section is smaller than the cross-sectional area at other locations of the sleeve 12. The location of the tapered section is not limited; it can be the end of the sleeve 12 or any section along the length of the sleeve 12.

[0057] Of course, in this embodiment, the sleeve 12 may not have a constriction section. The gap between the sleeve 12 and the pipeline can be sealed and fixed by filling with sealant or cement. The constriction section is attached to the outer wall of the pipeline to achieve sealing and fixation, which simplifies the overall structure and installation operation.

[0058] like Figure 1 and Figure 2 As shown, the outer peripheral wall of the sleeve 12 is separated from the peripheral side wall of the sealing part 1. Specifically, the sleeve 12 is not connected to the peripheral side wall of the sealing part 1. This arrangement can prevent the sleeve 12 from moving one side of the sealing part 1 when it is under force, thus avoiding the situation where the annular protrusion 11 on that side moves and affects the overall sealing performance, thereby ensuring the stability of the sealing assembly during use.

[0059] To be detailed, such as Figure 1 and Figure 2 As shown, the sleeve 12 may only be connected to the top end face of the sealing part 1 at its end, and the outer peripheral wall of the sleeve 12 may be separated from the sealing part 1 at all other positions except the end. Alternatively, the end of the sleeve 12 and a small part of the outer peripheral wall near the end may be connected to the sealing part 1, but may not be connected to the peripheral wall of the sealing part.

[0060] like Figure 2 As shown, there is an angle α between the axis of the sleeve 12 and the top end face of the sealing part 1. The size of the angle α between the axis of the sleeve 12 and the top end face of the sealing part 1 is not limited, but it is preferably in the range of 10°-90°. For example, it can be 10°, 12°, 30°, 45°, 60°, 90°, etc. Compared with the scheme of setting the angle in the range of less than 10°, such as 5°, 8°, etc., it can reduce the driving effect of the sleeve 12 on the top of the sealing part 1 when it is under force, thereby avoiding the situation where the sleeve 12 under force causes one side edge of the sealing part 1 to move, which leads to the movement of one side of the annular protrusion 11 and affects the overall sealing performance.

[0061] In addition, in this embodiment, the plate fixing part 23 of the skeleton 2 can be set according to the shape and size of the hole structure of the plate to ensure that the plate fixing part 23 can be stably fixed to the plate. The size of the bottom end face of the sealing part 1 is also set according to the size of the hole structure to ensure that the bottom end face of the sealing part 1 can cover the hole structure when the skeleton 2 is fixed to the plate, and that the annular protrusion 11 can fit against the surface of the plate along the circumference of the hole structure.
