Description

Technical Field

[0001] This application relates to the field of automotive parts technology, and in particular to a sealing structure for use at the rear of a vehicle and an automobile. Background Technology

[0002] Sealing strips are a key component of automotive sealing systems. Primarily used between gaps in vehicle body parts, their main function is to prevent rainwater, dust, and air from entering the vehicle interior from the outside. They also effectively reduce external noise, providing a comfortable and quiet cabin environment for passengers. Furthermore, good sealing performance improves aerodynamics, reduces air resistance, and thus improves fuel efficiency. Since sheet metal is a crucial part of the vehicle body, the connection method between it and the sealing strip directly affects the durability and reliability of the seal. Currently, sealing strips are mainly connected to sheet metal through adhesive bonding. Adhesives are used to attach the sealing strip to the sheet metal surface, providing a good seal. However, this method requires high-quality adhesives and precise application techniques. Poor adhesive quality or defects during application, such as incomplete surface preparation or uneven adhesive layer thickness, can lead to insufficient bond strength, causing the sealing strip to peel or detach during use. Moreover, adhesive bonding is relatively difficult to repair and replace. Damaged sealing strips require surface cleaning and re-bonding, increasing repair costs and time. Therefore, there is still a need for a sealing structure that can achieve a fast, efficient, and reliable connection between the rear sheet metal and the sealing strip. Utility Model Content

[0003] The technical problem to be solved by this application is to provide a sealing structure and automobile for use at the rear of a vehicle. By designing a connecting buckle with a double cap structure, the connection between the sealing strip and the connecting buckle is made tighter and more secure, reducing the risk of sealing failure due to loose connection, thereby improving the reliability of sealing performance.

[0004] The technical solution adopted in this application is: a sealing structure applied to the rear of a vehicle, including a sealing strip and a connecting buckle. The connecting buckle is used to connect the sealing strip and the rear sheet metal. One end of the connecting buckle is provided with a first cap and a second cap that are adapted to the sealing strip. Both the first cap and the second cap are fixedly connected to the sealing strip. The other end of the connecting buckle is used to connect to the rear sheet metal.

[0005] Compared with the prior art, the advantages of this application are that the sealing strip, as the main sealing component, is used to prevent rainwater, dust, air, and noise from entering the vehicle interior, thus playing a sealing role. It is usually made of materials with good elasticity and weather resistance, such as rubber or silicone. This application adds a connecting clip, which is a key component connecting the sealing strip and the rear sheet metal, serving to fix the sealing strip and the sheet metal parts. Its material is generally plastic or metal, possessing a certain strength and toughness, capable of withstanding vibrations and impacts during vehicle operation. The first clip portion and the second clip portion... At one end of the connecting clip, it is adapted to and fixedly connected to the sealing strip. The double cap design increases the contact area and connection strength between the sealing strip and the connecting clip, making the connection between the sealing strip and the connecting clip tighter and more secure. This reduces the risk of seal failure due to loose connection, thereby improving the reliability of sealing performance. The other end of the connecting clip is used to connect to the rear sheet metal, realizing the effective connection between the sealing strip and the sheet metal. During vehicle operation, even if subjected to vibration and impact, the double cap design makes the sealing strip less likely to fall off, thus ensuring the long-term stability of the sealing performance at the rear of the vehicle.

[0006] In some embodiments of this application, the first cap portion, the second cap portion, and the sealing strip are integrally vulcanized structures. In this application, the sealing strip is typically made of elastic materials such as rubber or silicone. Integral vulcanization means that the sealing strip, the first cap portion, and the second cap portion are molded into one piece in the same vulcanization process, forming a seamless connection between the sealing strip and the cap portion. This not only ensures the strength of the connection but also guarantees the sealing performance of the connection, eliminating gaps and weak points that may occur in traditional connection methods. It also reduces the risk of loosening or detachment of the connection due to vibration, impact, or temperature changes, and simplifies the assembly process during production.

[0007] In some embodiments of this application, both the first and second cap portions are fixed to the molding area of ​​the sealing strip. The molding area has a recessed portion adapted to the second cap portion, and the second cap portion is fixedly connected to the recessed portion. In this application, the molding area refers to a specific area on the sealing strip that has been molded, typically used for installing and fixing other components. The recessed portion is a recessed structure on the molding area designed to fit the shape of the second cap portion. This design allows the second cap portion to be precisely embedded in the recessed portion, achieving a tight fixed connection, ensuring the connection strength between the connecting buckle and the sealing strip, and enabling it to withstand vibrations and impacts during vehicle operation, thus ensuring the stability of the sealing strip during use.

[0008] In some embodiments of this application, the first and second cap portions are arranged vertically. In this application, the first and second cap portions together constitute the main part connecting the connecting buckle and the sealing strip. This dual-fixing method, with its vertical arrangement, greatly improves the connection strength between the sealing strip and the connecting buckle, reducing the risk of loosening or detachment due to vibration, impact, or temperature changes. Furthermore, the vertically arranged cap portions can better distribute and withstand various forces generated during vehicle operation, making the sealing strip more stable and less prone to deformation or displacement during use.

[0009] In some embodiments of this application, the first cap portion is disc-shaped, and the second cap portion is umbrella-shaped. In this application, the disc-shaped first cap portion has a flat top and rounded edges, providing a large contact area for a tight connection with the sealing strip. The flat top design makes the connection more robust and able to withstand greater pressure and tension. The umbrella-shaped second cap portion has a shape that expands outward from a central point, allowing it to provide support and fixation in multiple directions. The umbrella-shaped second cap portion can fit against the recesses on the sealing strip through its surface, enhancing the stability and reliability of the connection.

[0010] In some embodiments of this application, the connecting buckle is provided with a locking post, which is used to connect to the rear sheet metal of the vehicle. The outer wall of the locking post is provided with multiple blades, which are arranged parallel to each other along the length of the locking post. In this application, the locking post is part of the connecting buckle and is used to fix the connecting buckle to the rear sheet metal of the vehicle, thereby ensuring the stability and sealing performance of the sealing strip. The multiple blades on the outer wall of the locking post mainly increase the friction and contact area between the locking post and the sheet metal, thereby improving the fixing strength and stability of the locking post.

[0011] In some embodiments of this application, the blade has an umbrella-like structure, and the blade bends towards the second cap portion, while the second cap portion bends towards the blade. In this application, the blade is designed as an umbrella structure with a shape that expands outward from a central point, allowing the blade to provide support and fixation in multiple directions, enhancing the stability and reliability of the connection. The bending of the blade towards the second cap portion allows it to act as a guide during installation, helping the locking pin to be inserted more smoothly into the connection hole or slot on the sheet metal. The bending of the second cap portion towards the blade allows it to better cooperate with the blade during installation, forming a tight connection structure and further improving the stability of the entire connection buckle.

[0012] In some embodiments of this application, the outermost blade on the retaining post is provided with a gap, which is used to divide the blade into two symmetrical parts. In this application, by providing a gap, the outermost blade forms two independent symmetrical parts, giving the blade greater flexibility and adaptability at the end. This allows it to better adapt to the shape of the connecting holes or slots on the rear sheet metal, providing better fit and sealing. Furthermore, it allows the blade to be inserted more flexibly into the connecting holes or slots on the sheet metal during installation, reducing resistance and friction during installation and improving the convenience and efficiency of installation.

[0013] In some embodiments of this application, the rear sheet metal is provided with a connecting hole adapted to the connecting buckle. The other end of the connecting buckle passes through the connecting hole to lock the sealing strip to the rear sheet metal. In this application, the main function of the connecting hole is to provide a fixing point for the connecting buckle, allowing the connecting buckle to pass through the connecting hole and form a stable connection with the rear sheet metal. The shape and size of the connecting hole are optimized according to the design of the connecting buckle to ensure that the connecting buckle can be smoothly inserted and firmly fixed, making the sealing strip more stable during use, less prone to deformation or displacement, and making the installation process simpler and faster.

[0014] This application also provides an automobile, including any of the aforementioned sealing structures applied to the rear of the vehicle. In this application, the sealing structure is designed to be tightly integrated with the rear sheet metal of the automobile, forming a whole. The sealing structure is applied to the rear of the vehicle, and its main function is to prevent rainwater, dust, air, etc. from entering the vehicle, while reducing the transmission of external noise, improving the comfort and sealing performance of the vehicle interior. The sealing structure is fixedly connected to the rear sheet metal through connecting clips, ensuring the stability and sealing performance of the sealing strip.

[0019] The present application will now be described in detail with reference to the accompanying drawings.

[0020] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0021] A sealing structure for use at the rear of a vehicle, as shown in Embodiment 1 Figures 1 to 4 As shown: sealing strip 1 and connecting clip 2. Connecting clip 2 is used to connect sealing strip 1 and rear sheet metal 3. As the main sealing component, sealing strip 1 is used to prevent rainwater, dust, air and noise from entering the vehicle, thus playing a sealing role. It is usually made of materials with good elasticity and weather resistance, such as rubber and silicone. Connecting clip 2 is the key component connecting sealing strip 1 and rear sheet metal 3, which plays a role in fixing sealing strip 1 and sheet metal parts. Its material is generally plastic or metal, with a certain strength and toughness, and can withstand the vibration and impact during vehicle operation.

[0022] More specifically, one end of the connecting buckle 2 is provided with a first cap 21 and a second cap 22 that are adapted to the sealing strip 1. Both the first cap 21 and the second cap 22 are fixedly connected to the sealing strip 1. The other end of the connecting buckle 2 is used to connect to the rear sheet metal 3. The first cap 21 and the second cap 22 are both located at one end of the connecting buckle 2, adapted to and fixedly connected to the sealing strip 1. The double cap design can increase the contact area and connection strength between the sealing strip 1 and the connecting buckle 2, making the connection between the sealing strip 1 and the connecting buckle 2 tighter and more secure, reducing the risk of sealing failure due to loose connection, thereby improving the reliability of sealing performance. The other end of the connecting buckle 2 is used to connect to the rear sheet metal 3, realizing the effective connection between the sealing strip 1 and the sheet metal. During vehicle operation, even if subjected to vibration and impact, the double cap design makes the sealing strip 1 less likely to fall off, thereby ensuring the long-term stability of the sealing performance of the rear part.

[0023] More specifically, the first cap part 21, the second cap part 22 and the sealing strip 1 are integrally vulcanized structures. The sealing strip 1 is usually made of elastic materials such as rubber or silicone. Integral vulcanization means that the sealing strip 1 and the first cap part 21 and the second cap part 22 are formed into one piece in the same vulcanization process, so that the sealing strip 1 and the cap part form a seamless connection. This not only ensures the strength of the connection, but also guarantees the sealing of the connection part. It eliminates the gaps and weak points that may occur in traditional connection methods, reduces the risk of loosening or falling off the connection due to vibration, impact or temperature changes, and simplifies the assembly process in the production process.

[0024] More specifically, the first cap portion 21 and the second cap portion 22 are both fixed to the molding area 11 of the sealing strip 1. The molding area 11 is provided with a recessed portion 12 that matches the second cap portion 22. The second cap portion 22 is fixedly connected to the recessed portion 12. The molding area 11 refers to a specific area on the sealing strip 1 that has been molded and is usually used for installing and fixing other components. The recessed portion 12 is a recessed structure on the molding area 11 that matches the shape of the second cap portion 22. This design allows the second cap portion 22 to be precisely embedded in the recessed portion 12, achieving a tight fixed connection. This ensures the connection strength between the connecting buckle 2 and the sealing strip 1, and can withstand the vibration and impact during vehicle operation, ensuring the stability and reliability of the sealing strip 1 during use.

[0025] More specifically, the first cap portion 21 and the second cap portion 22 are distributed vertically. The first cap portion 21 and the second cap portion 22 together constitute the main part of the connection between the connecting buckle 2 and the sealing strip 1. The dual fixing method of vertical distribution greatly improves the connection strength between the sealing strip 1 and the connecting buckle 2, reduces the risk of loosening or falling off due to vibration, impact or temperature changes, and the vertically distributed cap portions can better distribute and bear the various forces generated during vehicle operation, making the sealing strip 1 more stable during use and less prone to deformation or displacement.

[0026] More specifically, the first cap portion 21 is disc-shaped, and the second cap portion 22 is umbrella-shaped. The disc-shaped first cap portion 21 has a flat top and a rounded edge, providing a large contact area and enabling it to be tightly connected with the sealing strip 1. The flat top design makes the connection more robust and able to withstand greater pressure and tension. The umbrella-shaped second cap portion 22 has a shape that expands outward from a center point, allowing the second cap portion 22 to provide support and fixation in multiple directions. The umbrella-shaped second cap portion 22 can be connected to the recessed portion 12 on the sealing strip 1 by fitting its surface, enhancing the stability and reliability of the connection.

[0027] Example 2, as Figures 1 to 5As shown, the connecting buckle 2 is provided with a locking post 23, which is used to connect the rear sheet metal 3. The outer wall of the locking post 23 is provided with multiple blades 24, which are arranged parallel to each other along the length of the locking post 23. The locking post 23 is part of the connecting buckle 2 and is used to fix the connecting buckle 2 to the rear sheet metal 3, thereby ensuring the stability and sealing performance of the sealing strip 1. The main function of the multiple blades 24 on the outer wall of the locking post 23 is to increase the friction and contact area between the locking post 23 and the sheet metal, thereby improving the fixing strength and stability of the locking post 23 and reducing the risk of loosening or falling off due to vibration, impact or temperature change.

[0028] More specifically, the blade 24 has an umbrella-shaped structure, with the blade 24 bent towards the second cap 22 and the second cap 22 bent towards the blade 24. The blade 24 is designed as an umbrella with a shape that expands outward from a central point, so that the blade 24 can provide support and fixation in multiple directions, enhancing the stability and reliability of the connection. The blade 24 is bent towards the second cap 22, which allows the blade 24 to play a guiding role during installation, helping the pin 23 to be inserted more smoothly into the connection hole 31 or slot on the sheet metal. The second cap 22 is bent towards the blade 24, so that the second cap 22 can better cooperate with the blade 24 during installation to form a tight connection structure, further improving the stability of the entire connection buckle 2.

[0029] More specifically, the last blade 24 on the retaining post 23 is provided with a gap 25. The gap 25 is used to divide the blade 24 into two symmetrical parts. By setting the gap 25, the last blade 24 forms two independent symmetrical parts, which makes the blade 24 more flexible and adaptable at the end. It can better adapt to the shape of the connecting hole 31 or the slot on the rear sheet metal 3, providing better fit and sealing. It also allows the blade 24 to be inserted into the connecting hole 31 or the slot on the sheet metal more flexibly during installation, reducing resistance and friction during installation and improving the convenience and efficiency of installation.

[0030] More specifically, the rear sheet metal 3 is provided with a connecting hole 31 that is adapted to the connecting buckle 2. The other end of the connecting buckle 2 passes through the connecting hole 31 to lock the sealing strip 1 and the rear sheet metal 3 together. The main function of the connecting hole 31 is to provide a fixing point for the connecting buckle 2, so that the connecting buckle 2 can pass through the connecting hole 31 and form a stable connection with the rear sheet metal 3. The shape and size of the connecting hole 31 are optimized according to the design of the connecting buckle 2 to ensure that the connecting buckle 2 can be smoothly inserted and firmly fixed, making the sealing strip 1 more stable during use and less prone to deformation or displacement, making the installation process simpler and faster.

The sealing structure is applied to the rear of the vehicle and its main function is to prevent rainwater, dust, air and other substances from entering the vehicle, while reducing the transmission of external noise and improving the comfort and sealing performance of the vehicle. The sealing structure is fixedly connected to the rear sheet metal 3 through the connecting buckle 2 to ensure the stability and sealing performance of the sealing strip 1.
