Description

Technical Field

[0001] This application relates to the field of vehicle body technology, and in particular to a sealing structure and a vehicle. Background Technology

[0002] In vehicle assembly, the use of fasteners such as bolts for connection and fixation is a common method. While this method ensures reliable connections between different components, water can easily seep through the gaps between the fasteners and body parts, causing leaks. This results in poor sealing at the connection points, which is detrimental to the overall quality of the vehicle. Utility Model Content

[0003] In view of this, this application aims to propose a sealing structure that can improve the sealing performance of the connection position of the connector, which is beneficial to the improvement of the overall quality of the vehicle.

[0004] To achieve the above objectives, the technical solution of this application is implemented as follows: A sealing structure is adapted to be fitted onto a connector and to seal the connection position of the connector, and includes an annular rigid skeleton and an elastic sealing body connected to the rigid skeleton. The elastic seal includes a first seal located on one side of the rigid skeleton, a second seal located on the other side of the rigid skeleton, and a third seal located at the inner hole of the rigid skeleton. The first sealing body, the second sealing body, and the third sealing body are all annular structures arranged circumferentially along the rigid skeleton. After the connector is connected, the first sealing body and the second sealing body can form a seal on both sides of the rigid skeleton, and the third sealing body can form a seal with the part of the connector that passes through the inner hole.

[0005] Furthermore, both the first sealing body and the second sealing body are convex outward relative to the rigid skeleton in the axial direction. The third sealing element protrudes radially into the inner hole of the rigid skeleton.

[0006] Furthermore, the elastic seal includes a connecting portion that connects the first seal and the second seal together, the connecting portion being embedded within the rigid skeleton.

[0007] Furthermore, the connecting portions are multiple portions spaced apart circumferentially along the rigid skeleton.

[0008] Furthermore, the third sealing body is provided with a first protrusion embedded in the rigid skeleton; The first protrusion extends axially along the rigid skeleton and is a plurality of protrusions spaced circumferentially along the rigid skeleton.

[0009] Furthermore, the third sealing body is provided with a second protrusion embedded within the rigid skeleton; The second protrusion extends circumferentially along the rigid skeleton and is adapted to restrict the third seal from dislodging from the inner hole.

[0010] Furthermore, the inner hole includes a first hole segment and a second hole segment connected together, wherein the inner diameter of the first hole segment is smaller than the inner diameter of the second hole segment; The third sealing body is disposed within the second hole section, and the inner diameter of the third sealing body is smaller than the inner diameter of the first hole section.

[0011] Furthermore, the rigid skeleton is made of plastic, and the elastic seal is made of rubber.

[0012] Furthermore, the sealing structure is formed using a two-color injection molding process.

[0013] Compared with related technologies, this application has the following advantages: (1) The sealing structure described in this application includes a first sealing body, a second sealing body and a third sealing body, which are connected to a rigid frame. After the connector is connected, the first sealing body and the second sealing body can form a seal on both sides of the rigid frame, and the third sealing body can also form a seal with the part of the connector that passes through the inner hole. Thus, by using the sealing of each sealing body at its own position, the various water seepage paths at the connection position of the connector can be effectively blocked, which can improve the sealing performance of the connection position of the connector and thus improve the overall quality of the vehicle.

[0014] (2) The first and second sealing bodies are both convex outward relative to the rigid skeleton in the axial direction, and the third sealing body is also convex into the inner hole in the radial direction of the rigid skeleton. The convex setting of the first and second sealing bodies and the convex setting of the third sealing body can facilitate the contact between each sealing body and the connecting parts or body parts after the connecting parts are connected, so as to form a compression seal by the sealing bodies. At the same time, the convex setting of the first and second sealing bodies and the convex setting of the third sealing body can also make the parts of the connecting parts or body parts that contact the sealing bodies only use simple planes, which helps to reduce the design and manufacturing cost of the body and facilitates the assembly operation of the body.

[0015] (3) By setting a connecting part that connects the first sealing body and the second sealing body together, the first sealing body and the second sealing body located on both sides of the rigid frame can be connected into one body through the connecting part. The mutual restraint between the first sealing body and the second sealing body on both sides can increase the stability of the first sealing body and the second sealing body on the rigid frame, which helps to improve the structural reliability of the sealing structure and improve the quality of use of the sealing structure.

[0016] (4) The connection between the first sealing body and the second sealing body is set to be multiple and spaced apart along the circumference of the rigid skeleton. On the one hand, the connection effect of multiple connection parts at different positions can be used to better ensure the stability of the first sealing body and the second sealing body on the rigid skeleton. On the other hand, the spacing between each connection part can be used to avoid adverse effects on the rigidity of the rigid skeleton and ensure the reliability of the rigid skeleton structure, which is conducive to improving the quality of the sealing structure.

[0017] (5) A first protrusion embedded in the rigid skeleton is provided on the third sealing body, such that the first protrusion extends along the axial direction of the rigid skeleton, and the first protrusion is a plurality of them spaced apart along the circumference of the rigid skeleton. This not only increases the contact area between the third sealing body and the rigid skeleton by using the multiple first protrusions, thus improving the stability of the first sealing body on the rigid skeleton, but also prevents the third sealing body from rotating by using the first protrusions that extend along the axial direction of the rigid skeleton. This can reduce the possibility of the third sealing body loosening due to the friction of the connecting parts after the connecting parts come into contact with the third sealing body, and further improve the stability of the first sealing body on the rigid skeleton.

[0018] (6) A second protrusion is provided on the third sealing body and embedded in the rigid skeleton, so that the second protrusion extends along the circumference of the rigid skeleton, and the second protrusion is set to restrict the third sealing body from coming out of the inner hole. The limiting effect of the second protrusion can be used to better improve the stability of the first sealing body on the rigid skeleton, which helps to improve the quality of the sealing structure.

[0019] (7) The inner hole on the rigid skeleton includes a first hole segment and a second hole segment with different inner diameters. The third sealing body is set in the second hole segment with a larger inner diameter, and the inner diameter of the third sealing body is smaller than the inner diameter of the first hole segment. On the one hand, compared with the design method of the third sealing body penetrating the entire inner hole along the rigid skeleton, the material used for the third sealing body can be reduced. At the same time, the shoulder position formed between the first hole segment and the second hole segment can be used to limit the third sealing body, which helps to further improve the stability of the first sealing body on the rigid skeleton. On the other hand, the first hole segment without the third sealing body can also play a certain centering role for the connectors that pass through the inner hole, which is conducive to ensuring the positional accuracy of the connectors after connection and ensuring the connection quality of the connectors.

[0020] (8) The rigid skeleton is made of plastic, which can take advantage of the easy molding and light weight of the plastic skeleton structure to reduce the manufacturing cost of the rigid skeleton and achieve the lightweight design of the rigid skeleton. At the same time, the elastic seal is made of rubber, which can take advantage of the excellent elasticity, good weather resistance and easy molding of the rubber seal to reduce the manufacturing cost of the elastic seal and make the elastic seal have excellent sealing performance, which helps to improve the overall quality of the sealing structure.

[0021] (9) The sealing structure is formed by two-color injection molding process, which can be adapted to the use of plastic for rigid skeleton and rubber for elastic sealing body, which facilitates the preparation of sealing structure and ensures the molding quality of sealing structure. It also helps to improve the production efficiency of sealing structure and reduce the production cost of sealing structure.

[0022] Another object of this application is to provide a vehicle having a sealing structure as described above on its body.

[0023] The vehicle described in this application has the advantages of the sealing structure as described above, which will not be repeated here. Attached Figure Description

In addition, if terms such as "first" or "second" appear, they are also used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0028] Furthermore, in the description of this application, unless otherwise expressly defined, the terms "installation," "connection," "joining," and "connector" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application in light of the specific circumstances.

[0029] In this application, the terms "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to a specific feature, structure, material, or characteristic described in connection with that embodiment or example, which is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0030] The present application will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0031] An embodiment of the first aspect of this application provides a sealing structure that is applied to a vehicle and is adapted to be fitted onto a connector 5 to seal the connection position of the connector 5. The sealing structure of this embodiment can effectively block the water seepage path at the connection position of the connector 5, thereby improving the sealing performance of the connection position of the connector 5 and thus contributing to the improvement of the overall quality of the vehicle.

[0032] In related technologies, using connectors such as bolts for connection and fixation is one of the common assembly methods between body parts. For example, the steering column bracket in the body is generally connected to the front bulkhead sheet metal by bolts, and the bolts used to connect the steering column bracket to the front bulkhead sheet metal also penetrate the front bulkhead sheet metal.

[0033] Taking the bolted connection between the steering column bracket and the front bulkhead sheet metal as an example, although this connection method can achieve a reliable connection between the steering column bracket and the front bulkhead sheet metal, water can easily seep through the gaps between the bolts and the front bulkhead sheet metal, causing leakage. This results in low sealing at the bolted connection, allowing water to enter the engine compartment and affecting its sealing effect, which is detrimental to the overall quality of the vehicle.

[0034] In view of this, in order to overcome the shortcomings of related technologies, the sealing structure of this embodiment combines... Figures 1 to 9 As shown, the overall design includes a ring-shaped rigid skeleton 1 and an elastic sealing body 2 connected to the rigid skeleton 1.

[0035] The elastic sealing body 2 includes a first sealing body 21 located on one side of the rigid skeleton 1, a second sealing body 22 located on the other side of the rigid skeleton 1, and a third sealing body 23 located at the inner hole 11 of the rigid skeleton 1.

[0036] Meanwhile, the first sealing body 21, the second sealing body 22 and the third sealing body 23 are all annular structures arranged circumferentially along the rigid skeleton 1. After the connector 5 is connected, the first sealing body 21 and the second sealing body 22 can form a seal on both sides of the rigid skeleton 1, and the third sealing body 23 can form a seal with the part of the connector 5 that passes through the inner hole 11.

[0037] Therefore, by making the elastic sealing body 2 connected to the rigid frame 1 include a first sealing body 21, a second sealing body 22 and a third sealing body 23, and after the connector 5 is connected, the first sealing body 21 and the second sealing body 22 can form a seal on both sides of the rigid frame 1, and the third sealing body 23 can also form a seal with the part of the connector that passes through the inner hole 11. In this embodiment, the sealing of each sealing body at its own position can effectively block each water seepage path at the connection position of the connector 5, thereby improving the sealing performance of the connection position of the connector 5.

[0038] Based on the above overview, specifically, it is worth noting that, as before... Figures 1 to 7 As shown, the annular rigid skeleton 1 in this embodiment is similar to a gasket, but with a greater thickness than a common gasket. The inner hole 11 on the rigid skeleton 1 is for the connector 5 to pass through, that is, the sealing structure of this embodiment is fitted onto the connector 5 through the inner hole 11.

[0039] Furthermore, the rigid skeleton 1 in this embodiment is similar to a gasket structure, and therefore has flat end faces formed on both sides of the rigid skeleton 1. The first sealing body 21 and the second sealing body 22 in the above-mentioned elastic sealing body 2 are disposed on the end faces of their respective corresponding sides, so as to achieve the sealing effect on both sides of the rigid skeleton 1 after the connector 5 is connected.

[0040] In this embodiment, it continues to be... Figure 1 , Figure 2 and combined Figure 4 As shown, in some of the exemplary embodiments, the first sealing body 21 and the second sealing body 22 are both convex outward relative to the rigid skeleton 1 in the axial direction, and the third sealing body 23 also protrudes into the inner hole 11 in the radial direction of the rigid skeleton 1.

[0041] In this way, by making the first sealing body 21 and the second sealing body 22 both protrude outward relative to the rigid frame 1 in the axial direction, and at the same time making the third sealing body 23 protrude into the inner hole 11 in the radial direction of the rigid frame 1, it can be understood that not only can the outward protrusion of the first sealing body 21 and the second sealing body 22, and the protrusion of the third sealing body 23 be utilized, but also the connection of the connecting member 5 can facilitate the contact between each sealing body and the connecting member 5 or the vehicle body component, so as to form a compression seal by the sealing body.

[0042] At the same time, by utilizing the outward protrusion of the first sealing body 21 and the second sealing body 22, as well as the protrusion of the third sealing body 23, the parts that come into contact with the sealing body, such as the connecting piece 5 or the body parts, can be made of simple planes, which helps to reduce the design and manufacturing costs of the body and also facilitates the assembly of the body.

[0043] In specific implementation, it should be noted that the amount of the first sealing body 21 and the second sealing body 22 protruding outward relative to the rigid skeleton 1, and the amount of the third sealing body 23 protruding into the inner hole 11, can usually be determined based on the material of the elastic sealing body 2 constituting each sealing body, as well as the connection and fastening force of the connector 5, etc. There are no restrictions on this, as long as it can achieve the sealing of the connection position of the connector 5 and ensure the sealing effect of the connection position of the connector 5.

[0044] In this embodiment, reference continues to be made to some of the exemplary implementations. Figure 3 As shown, the elastic seal 2 may further include, for example, a connecting portion 24 that connects the first seal 21 and the second seal 22 together, and the connecting portion 24 is also embedded in the rigid frame 1.

[0045] At this time, by providing a connecting part 24 that connects the first sealing body 21 and the second sealing body 22 together, it can be understood that the first sealing body 21 and the second sealing body 22 located on both sides of the rigid frame 1 can be connected into one unit through the connecting part 24. The mutual restraint between the first sealing body 21 and the second sealing body 22 located on both sides of the rigid frame 1 can increase the stability of the first sealing body 21 and the second sealing body 22 on the rigid frame 1, thereby helping to improve the structural reliability of the sealing structure and improving the quality of use of the sealing structure.

[0046] In practical implementation, structurally, it continues as follows: Figure 5 and Figure 6 As shown, the rigid skeleton 1 has a first receiving groove 12 and a second receiving groove 13 on both sides. The first receiving groove 12 and the second receiving groove 13 are both annular grooves arranged circumferentially along the rigid skeleton 1. The rigid skeleton 1 also has a through hole 14 arranged axially along the rigid skeleton 1 to connect the first receiving groove 12 and the second receiving groove 13.

[0047] The first sealing body 21 in the elastic sealing body 2 is disposed in the first receiving groove 12, and the second sealing body 22 is disposed in the second receiving groove 13. Correspondingly, the connecting part 24 for connecting the first sealing body 21 and the second sealing body 22 is disposed in the through hole 14. In this way, the first sealing body 21 and the second sealing body 22 are disposed on both sides of the rigid frame 1, and the connecting part 24 is embedded in the rigid frame 1.

[0048] In this embodiment, based on the above-described connection portion 24, in some exemplary embodiments, it is still combined with Figures 3 to 6 as well as Figure 8 As shown, for example, the connecting portions 24 can be a plurality of portions spaced apart along the circumference of the rigid skeleton 1.

[0049] In this way, by setting the connecting parts 24 between the first sealing body 21 and the second sealing body 22 to be multiple and spaced apart along the circumference of the rigid frame 1, on the one hand, the connection effect of multiple connecting parts 24 at different positions can be used to better ensure the stability of the first sealing body 21 and the second sealing body 22 on the rigid frame 1. On the other hand, the spacing between each connecting part 24 can be used to avoid the adverse effect of using a large-sized connecting part 24 on the rigid frame 1, thereby ensuring the reliability of the rigid frame 1 structure and also improving the quality of use of the sealing structure.

[0050] In this embodiment, a central hole 231 is formed in the third sealing body 23. The central hole 231 is coaxially arranged with the inner hole 11 on the rigid frame 1. When the body parts are connected by the connector 5, the connector 5 passes through the central hole 231 and abuts against the central hole 231 in an interference fit manner, thereby achieving a seal between the third sealing body 23 and the connector 5.

[0051] In addition, continue as Figure 9 As shown, in some exemplary embodiments, this embodiment may, for example, provide a first protrusion 232 embedded in the rigid skeleton 1 on the third sealing body 23, the first protrusion 232 extending axially along the rigid skeleton 1, and also such that the first protrusion 232 is a plurality of protrusions spaced apart circumferentially along the rigid skeleton 1.

[0052] It is understood that by providing a first protrusion 232 embedded in the rigid skeleton 1 on the third sealing body 23, and while the first protrusion 232 extends along the axial direction of the rigid skeleton 1, the first protrusion 232 is provided in multiple circumferentially spaced positions along the rigid skeleton 1. This embodiment can not only increase the contact area between the third sealing body 23 and the rigid skeleton 1 by using multiple first protrusions 232, but also improve the stability of the first sealing body 21 on the rigid skeleton 1.

[0053] Meanwhile, by utilizing the spaced first protrusions 232, especially since each first protrusion 232 extends along the axial direction of the rigid skeleton 1, this embodiment can obviously also play an anti-rotation role for the third sealing body 23. After the connector 5 comes into contact with the third sealing body 23, the possibility of the third sealing body 23 becoming loose due to the friction force of the connector 5 can be reduced, thereby further improving the stability of the first sealing body 21 on the rigid skeleton 1.

[0054] In practice, it is still as follows Figure 5 As shown, structurally, the aforementioned first protrusion 232 is embedded in the first groove 15 on the rigid frame 1. Moreover, it is worth noting that the dimensions of each of the aforementioned first protrusions 232 in the axial direction of the rigid frame 1 can generally be the same as the dimensions of the third sealing body 23 in the axial direction of the rigid frame 1, so as to facilitate the forming of the first protrusions 232 on the third sealing body 23.

[0055] Furthermore, the amount of embedment of each first protrusion 232 in the rigid skeleton 1 can be determined based on the materials of the third sealing body 23 and the rigid skeleton 1, and there are no restrictions on this, as long as it can effectively increase the stability of the third sealing body 23 on the rigid skeleton 1 and does not adversely affect the rigidity of the rigid skeleton 1 itself.

[0056] In this embodiment, it remains the same. Figure 9 As shown, in some exemplary embodiments, a second protrusion 233, which is also embedded in the rigid skeleton 1, may be provided on the third seal 23. The second protrusion 233 extends circumferentially along the rigid skeleton 1 and is also adapted to restrict the third seal 23 from dislodging from the inner hole 11.

[0057] Therefore, it can be understood that by providing a second protrusion 233 embedded in the rigid skeleton 1 on the third sealing body 23, the second protrusion 233 extends circumferentially along the rigid skeleton 1, and the second protrusion 233 is also configured to restrict the third sealing body 23 from being dislodged from the inner hole 11, this embodiment can utilize the limiting effect of the second protrusion 233 to better improve the stability of the first sealing body 21 on the rigid skeleton 1, which helps to improve the quality of use of the sealing structure.

[0058] For specific implementation, please refer to [link / reference]. Figure 5 As shown, structurally, the aforementioned second protrusion 233 is embedded in the second groove 16 on the rigid frame 1. Furthermore, see also... Figure 9 As shown, it is worth noting that, based on the first protrusion 232 also being provided on the third sealing body 23, since the dimensions of each first protrusion 232 in the axial direction of the rigid frame 1 can be the same as the dimensions of the third sealing body 23 in the axial direction of the rigid frame 1, the second protrusion 233 can be multiple segments disposed between each adjacent first protrusion 232. Correspondingly, the second groove 26 on the rigid frame 1 is also divided into multiple segments by each first groove 15, and each segment of the second protrusion 233 is embedded in the corresponding segment of the second groove 26.

[0059] In this embodiment, as follows... Figure 7As shown, in some exemplary embodiments, the inner hole 11 on the rigid skeleton 1 may include, for example, a first hole segment 111 and a second hole segment 112 connected together, wherein the inner diameter of the first hole segment 111 is smaller than the inner diameter of the second hole segment 112, and a third sealing body 23 is specifically disposed in the second hole segment 112, while the inner diameter of the third sealing body 23 is also smaller than the inner diameter of the first hole segment 111.

[0060] At this point, the inner hole 11 on the rigid skeleton 1 includes a first hole segment 111 and a second hole segment 112 with different inner diameters. The third sealing body 23 is placed in the second hole segment 112 with a larger inner diameter, and the inner diameter of the third sealing body 23 is also smaller than the inner diameter of the first hole segment 111. It can be understood that, compared with the design method of the third sealing body 23 penetrating the entire inner hole 11 along the rigid skeleton 1, this embodiment can obviously reduce the material used for the third sealing body 23, while using the shoulder position formed between the first hole segment 111 and the second hole segment 112 to limit the third sealing body 23, which helps to further improve the stability of the first sealing body 21 on the rigid skeleton 1.

[0061] On the other hand, by utilizing the first hole section 111 without the third sealing body 23, this embodiment can obviously also play a certain centering role for the connector 5 that passes through the inner hole 11, which is conducive to ensuring the positional accuracy of the connector 5 after connection and ensuring the connection quality of the connector 5.

[0062] In this embodiment, in some exemplary implementations, the rigid skeleton 1 may be made of plastic, for example, and the elastic sealing body 2 containing each sealing element may be made of rubber, for example.

[0063] This allows the rigid skeleton 1 to be made of plastic, leveraging the ease of molding and lightweight nature of plastic skeletons to reduce manufacturing costs and achieve a lightweight design. Conversely, by using rubber for the elastic seal 2, the excellent elasticity, weather resistance, and ease of molding of rubber seals can be utilized to reduce manufacturing costs and ensure excellent sealing performance, thus improving the overall quality of the sealing structure.

[0064] Since the rigid skeleton 1 is made of plastic and the elastic seal 2 is made of rubber, in specific implementations, for example, the rigid skeleton 1 can be made of common automotive plastics such as PVC (Polyvinyl Chloride), PP (Polypropylene), or PC (Polycarbonate), while the elastic seal 2 can be made of common automotive rubbers such as EPDM (Ethylene-Propylene-Diene Monomer).

[0065] Furthermore, based on the fact that the rigid skeleton 1 is made of plastic and the elastic sealing body 2 is made of rubber, in some exemplary embodiments, the sealing structure of this embodiment may be formed by a two-color injection molding process.

[0066] Two-color injection molding is a molding process that involves injecting two different materials into the same mold, resulting in a part formed from two materials. By using two-color injection molding for the sealing structure in this embodiment, it can be adapted to use a rigid skeleton 1 made of plastic and an elastic sealing body 2 made of rubber. This facilitates the preparation of the sealing structure, ensures the molding quality of the sealing structure, and also helps to improve the production efficiency and reduce the production cost of the sealing structure.

[0067] In practical implementation, the sealing structure based on this embodiment is formed by a two-color injection molding process. A suitable existing two-color mold is used, and plastic and rubber are injected in sequence to form the sealing structure of this embodiment.

[0068] It is worth noting that, regarding the sealing structure of this embodiment, based on the above exemplary embodiments, in specific implementation, as a preferred embodiment, it is still composed of... Figures 1 to 9 As shown, it may include, for example, a ring-shaped rigid skeleton 1 and an elastic sealing body 2 connected to the rigid skeleton 1.

[0069] The elastic sealing body 2 includes a first sealing body 21 located on one side of the rigid skeleton 1, a second sealing body 22 located on the other side of the rigid skeleton 1, and a third sealing body 23 located at the inner hole 11 of the rigid skeleton 1. The first sealing body 21, the second sealing body 22 and the third sealing body 23 are all annular structures arranged circumferentially along the rigid skeleton 1.

[0070] The first sealing body 21 and the second sealing body 22 are both convex outward relative to the rigid frame 1 in the axial direction, and the third sealing body 23 also protrudes into the inner hole 11 in the radial direction of the rigid frame 1. At the same time, the elastic sealing body 2 also includes a connecting part 24 that connects the first sealing body 21 and the second sealing body 22 together, and there are multiple connecting parts 24 that are spaced apart along the circumference of the rigid frame 1.

[0071] In addition, the third sealing body 23 is provided with a first protrusion 232 and a second protrusion 233 embedded in the rigid skeleton 1. The first protrusion 232 extends axially along the rigid skeleton 1 and is a plurality of protrusions spaced apart circumferentially along the rigid skeleton 1. The second protrusion 233 extends circumferentially along the rigid skeleton 1 and is adapted to restrict the third sealing body 23 from being dislodged from the inner hole 11.

[0072] In addition, the rigid skeleton 1 is made of plastic, the elastic sealing body 2 is made of rubber, and the sealing structure in this preferred embodiment is also formed by a two-color injection molding process.

[0073] In the preferred embodiment of the sealing structure above, the specific configuration and arrangement of the rigid skeleton 1 and the elastic sealing body 2 can still be referred to the descriptions in the above exemplary embodiments. Furthermore, in this preferred embodiment, the beneficial effects brought about by the design of the rigid skeleton 1 and the elastic sealing body 2 can also be referred to the descriptions in the above exemplary embodiments.

[0074] And continue as Figure 10 As shown, taking the sealing structure in the preferred embodiment above as an example, in use, the connecting member 5 can generally be a bolt, and a nut 6, a flat washer 7, and a spring washer 8 are provided to match the connecting member 5. At the same time, the connecting member 5 is used to fix the fixed member 4 to the body sheet metal 3, and the body sheet metal 3 can be, for example, the front sheet metal in the body, and the fixed member 4 can be, for example, a steering column bracket.

[0075] During connection, the sealing structure is first fitted onto the connector 5, allowing the connector 5 to pass through the connection holes on the body sheet metal 3 and the fixed part 4 in sequence. Then, the nut 6 is screwed on and tightened. After the nut 6 is tightened, the first sealing body 21 of the elastic sealing body 2 on the sealing structure abuts against the flat washer 7, forming a seal at the second sealing position b. The second sealing body 22 abuts against the body sheet metal 3, forming a seal at the first sealing position a. At the same time, the third sealing body 23 also abuts against the portion of the connector 5 located in the inner hole 11, forming a seal at the third sealing position c. In this way, through the sealing action of each sealing body, the various water seepage paths at the connection position of the connector 5 can be effectively blocked, achieving a complete seal.

[0076] The sealing structure of this embodiment adopts the above design. It can effectively block the water seepage paths at the connection position of the connector 5 by utilizing the sealing of each seal body in the elastic sealing body 2 at its own position. This can improve the sealing performance of the connection position of the connector 5, ensure the sealing effect of the vehicle body, and thus help improve the overall quality of the vehicle.

[0077] An embodiment of the second aspect of this application provides a vehicle having a sealing structure as described in the first aspect embodiment above on its body.

[0078] In the vehicle of this embodiment, the connecting member 5 can generally be a bolt, and in addition to the sealing structure provided at the connection position between the steering column and the front bulkhead sheet metal as described in the first aspect embodiment, the sealing structure can also be provided at other positions where the connecting member 5 is used and sealing is required.

[0079] The vehicle in this embodiment, by adopting the sealing structure described above, can effectively block each water seepage path at the connection position of the connector 5, thereby improving the sealing performance of the connection position of the connector 5, ensuring the sealing effect of the vehicle body, and thus contributing to the improvement of the overall quality of the vehicle.

[0080] The above descriptions are merely some embodiments of this application and are not intended to limit this application. The technical features or structures in the foregoing different embodiments can be arbitrarily combined to form other specific technical solutions as needed. For those skilled in the art, this application can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of the claims of this application.
