Durable automobile skirt with high air tightness

Abstract

This utility model discloses a durable automotive side skirt with high airtightness, including a side skirt body with a reinforcing layer inside and a sealing component on the front outer side of the side skirt body. The sealing component includes a rigid patch with a flexible patch inside the rigid patch, the flexible patch being longer than the rigid patch in front. When the side skirt is installed, the flexible patch contacts the car body and is compressed to a certain extent. Through its own elastic deformation, it fills the tiny gaps between the side skirt and the car body, achieving a primary seal. Simultaneously, the rigid patch and the car body are transitioned through the flexible patch, forming a secondary seal. By adopting a double-layer flanged sealing structure and an interference fit design, a multi-level seal is formed, which can fully fill the gaps between the side skirt and the car body, significantly improving the overall airtightness of the side skirt, effectively preventing rainwater and dust from seeping into the bottom of the car body, and avoiding corrosion of internal components.

Description

Technical Field

[0001] This utility model relates to the field of automotive side skirt technology, specifically a durable automotive side skirt with high airtightness. Background Technology

[0002] Car side skirts are important aesthetic and functional components installed on both sides of the bottom of a car body. Extending along the length of the car body, they not only optimize the visual effect of the side of the car and make the body lines smoother and more harmonious, but also provide a certain degree of protection for the bottom structure of the car body during driving, reducing the direct impact of mud, sand and stones on the bottom of the car body on key components. At the same time, they can help guide the airflow around the car body and reduce wind resistance to a certain extent. They are a component of the car body system that combines decoration and practicality.

[0003] However, most existing car side skirts use a simple adhesive sealing method, which usually involves directly bonding them to the outside of the car body and then fixing them with screws on both sides. This structure makes it difficult to fully fill the tiny gaps between the side skirt and the car body, allowing rainwater and dust to easily seep in through the gaps when the vehicle is in motion. This not only affects the cleanliness of the bottom of the car body but may also corrode the metal parts inside the car body, shortening the service life of the parts. Utility Model Content

[0004] The purpose of this invention is to provide a durable automotive side skirt with high airtightness, in order to solve the problem mentioned in the background art that existing automotive side skirts mostly use simple adhesive sealing.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A durable automotive side skirt with high airtightness includes a side skirt body, wherein a reinforcing layer is provided inside the side skirt body, and a sealing component is provided on the front outer side of the side skirt body;

[0007] The sealing assembly includes a rigid patch, and a flexible patch is disposed inside the rigid patch, wherein the front length of the flexible patch is longer than that of the rigid patch.

[0008] In a preferred embodiment of this utility model, the skirt body is made of glass fiber reinforced modified PP material, and the reinforcing layer is made of glass fiber reinforced modified PA66 biomimetic honeycomb reinforcing rib material.

[0009] In a preferred embodiment of this utility model, a sound insulation layer is provided on the inner front side of the skirt body, and the sound insulation layer is made of a composite material of butyl rubber and EPDM foam.

[0010] In a preferred embodiment of this utility model, the rigid patch is hollow and is made of glass fiber reinforced modified PP material.

[0011] In a preferred embodiment of this utility model, the flexible patch is hollow and is made of silicone rubber modified EPDM material.

[0012] In a preferred embodiment of this utility model, bending plates are provided on both sides of the front of the skirt body, and fixing openings are provided on the bending plates.

[0013] In a preferred embodiment of this utility model, a first sealing ring is provided on the inner side of the fixing port, and a second sealing ring is provided on the outer side of the fixing port.

[0014] In a preferred embodiment of this utility model, the first sealing ring and the second sealing ring are annular, and the first sealing ring and the second sealing ring are made of nitrile rubber.

[0015] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.

[0016] Beneficial effects: During the installation of the side skirt, the flexible patch contacts the vehicle body and is compressed to a certain extent. Through its own elastic deformation, it fills the tiny gaps between the side skirt and the vehicle body, achieving a primary seal. Simultaneously, the rigid patch and the vehicle body form a secondary seal through the transition of the flexible patch. This dual-seal structure improves the airtightness of the side skirt by over 90%. Furthermore, after the side skirt is installed, the compression of the flexible patch provides excellent protection while simultaneously sealing it. This prevents the flexible patch from direct contact with external stones and mud, extending the service life of the sealing components. The use of a double-layer flanged sealing structure with an inner elastic material and an outer rigid structure, combined with an interference fit design, creates a multi-level seal that effectively fills the gaps between the side skirt and the vehicle body, significantly improving the overall airtightness of the side skirt and effectively preventing rainwater and dust from seeping into the bottom of the vehicle body, thus avoiding corrosion of internal components.

[0023] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0024] Please refer to Figures 1-3 This utility model discloses a durable car side skirt with high airtightness, including a side skirt body 1, which is the side skirt of the car. The shape of the side skirt body 1 is set according to the car body and can be set to any shape to match different car bodies. The side skirt body 1 is made of glass fiber reinforced modified PP material, which has both lightweight and weather resistance. It can maintain structural stability in the common automotive ambient temperature range of -30℃ to 80℃, while reducing the overall weight of the side skirt and reducing the load on the car body.

[0025] The skirt body 1 has a reinforcing layer 11 inside. The reinforcing layer 11 is made of glass fiber reinforced modified PA66 biomimetic honeycomb reinforcing material and is integrally injection molded with the skirt body 1. This can increase the bending strength of the skirt by more than 60%, preventing the skirt from deforming or breaking due to road bumps and stone impacts during vehicle operation, thus extending its service life. The inner front side of the skirt body 1 has a sound insulation layer 12. The sound insulation layer 12 is made of butyl rubber and EPDM foam composite material. The sound insulation layer 12 is fixedly connected to the skirt body 1 at the rear. The high damping characteristics of butyl rubber can absorb road vibration noise, and the porous structure of EPDM foam can block airborne sound transmission. The synergistic effect of the two can reduce road noise in the vehicle by 8-12dB, improving the quietness of the ride.

[0026] A sealing component is provided on the outer front side of the skirt body 1. The sealing component includes a rigid patch 2, and a flexible patch 21 is provided on the inner side of the rigid patch 2. Both the rigid patch 2 and the flexible patch 21 are designed according to the actual situation of the skirt. That is, the rigid patch 2 is located at the front edge of the skirt body 1, while the flexible patch 21 is fixedly connected to the skirt body 1 at the rear. The rigid patch 2 is made of rigid material and has a hollow shape. The rigid patch 2 is made of glass fiber reinforced modified PP material, that is, the rigid patch 2 is made of the same material as the skirt body 1, and the rigid patch 2 and the skirt body 1 are an integral structure. After the skirt is installed, due to a certain degree of compression of the flexible patch 21, the rigid patch 2 can seal the flexible patch while simultaneously preventing it from swaying. The flexible patch 21 provides a good wrapping effect, thus protecting the flexible patch 21 and preventing it from being directly exposed to external stones and mud, which can cause wear and tear and extend the service life of the sealing components. The front length of the flexible patch 21 is longer than that of the rigid patch 2. The flexible patch 21 is hollow and made of silicone rubber modified EPDM material. When the skirt is installed, the flexible patch 21 contacts the vehicle body and is compressed to a certain extent. Through its own elastic deformation, it fills the tiny gaps between the skirt and the vehicle body, achieving a primary seal. At the same time, the rigid patch 2 and the vehicle body are connected by the transition of the flexible patch 21, forming a secondary seal. The double sealing structure can improve the airtightness of the skirt by more than 90%.

[0027] The skirt body 1 has bending plates 3 on both sides at the front. The bending plates 3 correspond to the installation positions on the vehicle body. The bending plates 3 have fixing holes 31. The position of the fixing holes 31 is set according to the actual situation. After the flexible patch 21 is compressed, the fixing holes 31 are connected to the screw holes of the vehicle body. At this time, the screw passes through the fixing holes 31 and is tightened in the screw holes to fix the skirt. The inner side of the fixing holes 31 is provided with a first sealing ring 32 and the outer side of the fixing holes 31 is provided with a second sealing ring 33. The first sealing ring 32 and the second sealing ring 33 are annular. The first sealing ring 32 and the second sealing ring 33 are made of nitrile rubber. When the screw is installed, the first sealing ring 32 is compressed and contacts the vehicle body by squeezing, while the screw head contacts the second sealing ring 33 and compresses the second sealing ring 33, thereby achieving a seal at the fixing part.

[0028] The working principle of this utility model is as follows: The reinforcing layer 11 is made of glass fiber reinforced modified PA66 biomimetic honeycomb reinforcing material and is integrally injection molded with the skirt body 1, which can improve the bending strength of the skirt by more than 60%, avoid deformation or breakage of the skirt due to road bumps and stone impacts during vehicle operation, and extend its service life. When the skirt is installed, the flexible patch 21 contacts the vehicle body and is compressed to a certain extent. Through its own elastic deformation, it fills the tiny gap between the skirt and the vehicle body, achieving a primary seal. At the same time, the rigid patch 2 and the vehicle body form a secondary seal through the transition of the flexible patch 21. The double sealing structure can improve the airtightness of the skirt by more than 90%. After the skirt is installed, due to the compression of the flexible patch 21, the rigid patch 2 provides a good wrapping effect on the flexible patch 21 while sealing, thus protecting the flexible patch 21 and preventing it from being directly exposed to external stones and mud, thus extending the service life of the sealing components.
