Description

Technical Field

[0001] This utility model relates to the field of automotive door rubber ring technology, specifically a dense rubber ring with multiple cross-sectional shapes. Background Technology

[0002] Door rubber rings, also known as door seals, are important sealing components between the car door frame and the door, typically made of highly elastic rubber. Their main function is to ensure a good seal when the door is closed, preventing dust, moisture, noise, and sand from entering the vehicle, thus improving driving comfort and safety. Door rubber rings also effectively cushion impacts to the door, reducing friction between the door panel and the vehicle body.

[0003] However, existing car door rubber rings are usually one-piece molded structures composed of a single layer of rubber material. During use, the single layer of rubber material will age over a long period of time, resulting in reduced sealing performance. Moreover, frequent opening and closing of car doors puts a lot of pressure on the door rubber ring, and the stability of a single layer of rubber material is not high. Therefore, we propose a dense rubber ring with multiple cross-sectional shapes. Utility Model Content

[0004] The purpose of this invention is to provide a dense rubber ring with multiple cross-sectional shapes to solve the problems mentioned in the background art. Currently, car door rubber rings on the market are usually composed of a single layer of rubber material. After long-term use, the single layer of rubber material will age, resulting in reduced sealing performance. In addition, frequent opening and closing of car doors puts a lot of pressure on the car door rubber ring.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-section shape dense rubber ring, including a tubular hollow part and an air release surface, wherein a hollow opening is provided in the middle of the tubular hollow part, the air release surface is provided on the outside of the tubular hollow part, one end of the tubular hollow part is provided with an integrally formed first sealing part, second sealing part and support mechanism, and the support mechanism is connected to the second sealing part, the tubular hollow part is annular, and the first sealing part and second sealing part are U-shaped.

[0006] Preferably, the support mechanism includes a first support part, a second support part, a third support part, and a support root part, and one end of the tubular hollow part is provided with a support root part connected to the second sealing part.

[0007] Preferably, the first support part, the second support part, and the third support part are connected at the angle between the support root and the second sealing part.

[0008] Preferably, the inner side of the first sealing part is connected to a first convex surface and a third convex surface, and the first convex surface is located near the end of the first sealing part, and the inner side of the second sealing part is provided with a second convex surface.

[0009] Preferably, a reinforcing layer is adhered to the inner side of the first sealing part, the first convex surface, the second convex surface, the third convex surface, and the second sealing part, and the reinforcing layer matches the surface shape of the first convex surface, the second convex surface, and the third convex surface.

[0010] Preferably, the surface at the connection between the tubular hollow part and the support root is provided with an adhesive surface and a snap-fit ​​part, and the surface of the air release surface is provided with a plurality of recesses.

[0011] Preferably, the surface of the air release surface near the concave point is provided with a plurality of protrusions, and the protrusions and concave points are distributed at equal intervals.

[0012] Preferably, an inner tube is attached to the inside of the hollow opening, and both the inner tube and the reinforcing layer are made of polyurethane.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. Equipped with a support mechanism, the No. 1 and No. 2 sealing parts achieve double-layer sealing, and the extension distance of the No. 1 sealing part is greater than that of the No. 2 sealing part, further improving the sealing performance. At the same time, the cross-sections of the No. 1, No. 2, and No. 3 convex surfaces are irregularly shaped, and the No. 1, No. 2, and No. 3 support parts are designed with arc-shaped structures. This allows the No. 1, No. 2, and No. 3 convex surfaces to be evenly stressed when the car door is closed. Simultaneously, the No. 1, No. 2, and No. 3 support parts distribute the pressure, making the overall stress more uniform. This allows the door rubber ring to maintain better elasticity and recovery force when compressed, avoiding excessive compression in certain parts that could lead to unstable sealing performance or localized wear, extending service life, and improving the stability of the door rubber ring.

[0015] 2. It features a reinforcing layer, an inner tube, recessed dots, and raised dots. The reinforcing layer increases the number of layers in the door rubber ring's buffer area. The inner tube is fitted inside the hollow section to improve the elasticity of the tubular hollow part. The reinforcing layer and inner tube are made of polyurethane, which has good sound insulation properties, reduces the intrusion of external noise, and improves aging resistance. Since the air release surface is in contact with the car frame, several recessed dots and raised dots provide an uneven texture to the air release surface. Through surface undulations of different heights, the sound insulation and waterproofing effects of the door rubber ring are further enhanced, improving the practicality of the door rubber ring.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 This utility model provides a technical solution: a dense rubber ring with a multi-section shape, including a tubular hollow part 1 and an air release surface 4. The tubular hollow part 1 has a hollow opening 3 in the middle. The air release surface 4 is located on the outside of the tubular hollow part 1. The surface at the connection between the tubular hollow part 1 and the support root 804 is provided with an adhesive surface 11 and a snap-fit ​​part 12.

[0023] Please see Figures 1-4 The tubular hollow portion 1 has an integrally formed first sealing portion 5, second sealing portion 10, and support mechanism 8 at one end, and the support mechanism 8 is connected to the second sealing portion 10. The tubular hollow portion 1 is annular, and the first sealing portion 5 and the second sealing portion 10 are U-shaped. The support mechanism 8 includes a first support portion 801, a second support portion 802, a third support portion 803, and a support root portion 804. One end of the tubular hollow portion 1 is provided with a support connected to the second sealing portion 10. The root portion 804 is connected to the first support portion 801, the second support portion 802, and the third support portion 803 at the angle adjacent to the second sealing portion 10. The inner side of the first sealing portion 5 is connected to the first convex surface 6 and the third convex surface 9, and the first convex surface 6 is close to the end of the first sealing portion 5. The inner side of the second sealing portion 10 is provided with the second convex surface 7. The first support portion 801, the second support portion 802, and the third support portion 803 are all designed with an arc-shaped structure.

[0024] In practical implementation, existing car door rubber rings are usually one-piece molded structures composed of a single layer of rubber material. During use, this single layer of rubber material ages over time, leading to reduced sealing performance. Furthermore, frequent opening and closing of the car door puts significant pressure on the rubber ring, and the stability of a single layer of rubber material is not high. By using sealing parts 5 and 10 to contact the car frame, and based on the sealing of the tubular hollow part 1, sealing parts 5 and 10 achieve a double-layer seal. Moreover, the extension distance of sealing part 5 is greater than that of sealing part 10, further improving the sealing performance. The cross-sections of convex surface 6, convex surface 7, and convex surface 9 are irregularly shaped. Support parts 801, 802, and 803 are designed with arc-shaped structures. When the car door is closed, convex surfaces 6, 7, and 9 can be evenly stressed. At the same time, support parts 801, 802, and 803 disperse the pressure, making the overall stress more uniform. This allows the door rubber ring to maintain better elasticity and resilience when compressed, avoiding excessive compression in certain areas that could lead to unstable sealing or localized wear, thus extending its service life and improving the stability of the door rubber ring.

[0025] Please see Figures 1-4 A reinforcing layer 13 is adhered to the inner side of the first sealing part 5, the first convex surface 6, the second convex surface 7, the third convex surface 9, and the second sealing part 10. The reinforcing layer 13 matches the surface shape of the first convex surface 6, the second convex surface 7, and the third convex surface 9. Several recesses 14 are formed on the surface of the air release surface 4. Several protrusions 15 are formed on the surface of the air release surface 4 near the recesses 14, and the protrusions 15 and the recesses 14 are evenly distributed. An inner tube 2 is adhered to the inner side of the hollow opening 3. The inner tube 2 and the reinforcing layer 13 are both made of polyurethane.

[0026] In practice, the door rubber ring usually has only one layer, resulting in poor sound insulation. The number of layers in the buffer area of ​​the door rubber ring can be increased by adding a reinforcing layer 13. Then, an inner tube 2 is fitted inside the hollow opening 3 to improve the elasticity of the tubular hollow part 1. The reinforcing layer 13 and the inner tube 2 are made of polyurethane, which has good sound insulation, reduces the transmission of external noise, and improves anti-aging properties. Since the air release surface 4 is in contact with the car frame, several concave points 14 and convex points 15 provide an uneven texture to the air release surface 4. Through the surface undulations at different heights, the sound insulation and waterproof effect of the door rubber ring can be further enhanced, improving the practicality of the door rubber ring.

[0027] Working principle: When using this multi-section dense rubber ring, it first contacts the car frame through the first sealing part 5 and the second sealing part 10. Under the sealing foundation of the tubular hollow part 1, the first sealing part 5 and the second sealing part 10 achieve double sealing. The first convex surface 6, the second convex surface 7 and the third convex surface 9 can be evenly stressed. At the same time, the first support part 801, the second support part 802 and the third support part 803 disperse the pressure, making the overall stress more uniform. It can maintain better elasticity and recovery force when the door rubber ring is compressed, avoiding the situation where some parts are over-compressed, resulting in unstable sealing effect or local wear. The reinforcing layer 13 and the inner tube 2 are made of polyurethane, which has good sound insulation effect. Several concave points 14 and convex points 15 provide uneven texture to the air release surface 4. Through the surface undulations of different heights, the sound insulation and waterproof effect of the door rubber ring can be further enhanced, improving the practicality of the door rubber ring. The contents not described in detail in this specification are prior art known to those skilled in the art.

[0028] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
