Description

Technical Field

[0001] This utility model belongs to the field of vehicle door technology, specifically relating to an improved structure of door opening sealing strip. Background Technology

[0002] The vehicle door is a crucial functional system within the cab and also a vital sealing system. Door sealing encompasses both the door's own seal and the seal between the door and the vehicle body. The door's own seal refers to the external seal of the window glass and the internal seals of components such as the door's inner panel and waterproof membrane. The seal between the door and the vehicle body refers to the door's seal strips and secondary seals on the side panels. The purpose of this sealing is to prevent water from entering the door and the cab. The sealing structure on the vehicle body plays a crucial role in waterproofing, dustproofing, and reducing wind noise. However, the side panel door seal strips, due to their complex assembly, are prone to separating from the trim strips under door pressure, creating gaps. This allows water and dust to easily penetrate the vehicle's interior, affecting wind and noise reduction. Especially in extreme conditions, such as underground parking garages with water depths exceeding 1 meter or vehicles entering lakes, a good door seal is essential to prevent water leakage for at least half an hour, protecting vehicle safety, avoiding property damage, and providing passengers with sufficient escape time. Existing sealing systems cannot withstand water pressure; when a vehicle plunges into a lake, water can instantly enter the vehicle, causing panic and even death. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an improved structure for door opening sealing strips that is simple in structure, can effectively resist extreme working conditions, and has good sealing performance, in light of the current state of the technology.

[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: an improved structure for door opening sealing strip, including a body, a metal skeleton and a bubble tube, wherein the metal skeleton is embedded in the body and formed together with the body, the body and the metal skeleton form an inverted U-shaped mounting groove, the bubble tube is connected to the outside of the body, the bubble tube and the left side of the body form a first cavity, and the bubble tube and the upper part of the body form a second cavity.

[0005] In the aforementioned improved door opening sealing strip structure, the foam tube body is divided into an upper cross-section foam tube and a lower cross-section foam tube along the door waistline. The thickness of the lower cross-section foam tube is greater than that of the upper cross-section foam tube. This patent primarily utilizes a variable cross-section mold technology to maintain the original thickness of the upper cross-section foam tube, thus ensuring a certain degree of elasticity. Furthermore, by increasing the thickness of the lower cross-section foam tube and enlarging the foam shape, the compressive load of the product is improved. For example, increasing the sponge tube wall thickness by 0.7mm and the foam interference by 1mm increases the compressive load to 15N / 100mm, which can solve the water seepage problem under wading conditions for vehicles.

[0006] In the above-mentioned improved structure of door opening sealing strip, three anti-detachment protrusions are arranged from top to bottom on the left side wall of the mounting groove, and two anti-detachment lips are provided on the right side wall of the mounting groove.

[0007] In the above-mentioned improved structure of door opening sealing strip, the lower part of the mounting groove is provided with an abutment lip.

[0008] In the aforementioned improved door opening sealing strip structure, the lower inner part of the first cavity has a lower deformation fold, and the upper outer part of the first cavity has an upper deformation fold. Here, the upper and lower deformation folds achieve compression deformation of the first cavity, ensuring good sealing performance.

[0009] In the aforementioned improved structure of a door opening sealing strip, a pull rope is provided inside the second cavity.

[0010] The pull cord can be made of either dense EPDM rubber or low-density EPDM rubber. Using low-density EPDM rubber reduces weight, thereby further increasing the vehicle's driving range.

[0011] In the aforementioned improved door opening sealing strip structure, a waterproof lip is provided at the port of the second cavity. This waterproof lip enhances the waterproof performance.

[0012] In the above-mentioned improved structure of door opening sealing strip, the main body, metal skeleton, bubble tube and pull rope are integrally formed.

[0013] Compared with the prior art, the advantages of this utility model are that by extruding a variable cross-section bubble tube body through an extrusion nozzle, not only is easy installation achieved, but the bubble tube part below the waistline is thickened, which increases the compressive load of the product and solves the water seepage problem under the vehicle wading conditions. The entire door opening sealing strip improves the pull-out force through anti-detachment protrusions, anti-detachment lips and abutment lips, thereby preventing the sealing strip from falling off the door opening stop. Attached Figure Description

[0014] Figure 1 This is a schematic diagram of the improved structure of the door opening sealing strip. Detailed Implementation

[0015] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0016] In the figure, the main body is 100; the metal skeleton is 200; the bubble tube is 300; the cross-section of the bubble tube above the waistline is 301; the cross-section of the bubble tube below the waistline is 302; the mounting groove is 400; the waterproof lip is 500; the first cavity is 600; the second cavity is 700; the pull rope is 800; the anti-detachment protrusion is 900; the anti-detachment lip is 1000; the abutment lip is 1001; the lower deformation fold is 1002; and the upper deformation fold is 1003.

[0017] like Figure 1 As shown, the improved structure of this door opening sealing strip includes a body 100, a metal skeleton 200, and a bubble tube 300. The metal skeleton 200 is embedded within the body 100 and formed together with the body 100. The metal skeleton 200 enhances the strength of the entire door opening sealing strip. To facilitate installation, the body 100 and the metal skeleton 200 form an inverted U-shaped mounting groove 400. The bubble tube 300 is connected to the outer side of the body 100. The bubble tube 300 and the left side of the body 100 form a first cavity 600. The upper part has a second cavity 700, where compression deformation can be achieved through the first cavity 600 and the second cavity 700, thereby ensuring the sealing of the installation; a pull rope 800 is provided in the second cavity 700, which can be made of EPDM solid rubber or low specific gravity EPDM rubber. The use of low specific gravity EPDM rubber achieves weight reduction. Glass fiber is provided in the pull rope 800, which can enhance the strength of the pull rope, thereby further improving the driving range of the vehicle. The main body 100, the metal skeleton 200, the bubble tube 300 and the pull rope 800 are integrally formed.

[0018] The foam tube body 300 of this patent is divided into a foam tube 301 with an upper cross section 301 and a foam tube 302 with a lower cross section 302 along the waistline of the car door. The thickness of the foam tube 302 with a lower cross section 302 is greater than that of the foam tube 301 with an upper cross section 301. This patent mainly uses a mold variable cross section extrusion technology. That is to say, the foam tube 301 with an upper cross section 301 uses the original thickness, while the thickness of the foam tube 302 with a lower cross section 302 is increased and the foam shape is enlarged. This can not only achieve smooth installation of the product, but also increase the product's compressive load. For example, if the wall thickness of the sponge tube is increased by 0.7mm and the foam interference is increased by 1mm, the compressive load is increased to 15N / 100mm.

[0019] Three anti-detachment protrusions 900 are arranged from top to bottom on the left side wall of the mounting groove 400. Two anti-detachment lips 1000 are provided on the right side wall of the mounting groove 400. An abutment lip 1001 is provided at the lower part of the mounting groove 400. The anti-detachment protrusions 900 and anti-detachment lips 1000 increase the pull-out force, and the abutment lip 1001 prevents the sealing strip from falling off the door opening stop. The lower inner side of the first cavity 600 has a lower deformation fold 1002, and the upper outer side of the first cavity 600 has an upper deformation fold 1003. The upper deformation fold 1003 and the lower deformation fold 1002 achieve the first The compression deformation of cavity 600 ensures good sealing performance. A waterproof lip 500 is provided at the port of the second cavity 700, which enhances the waterproof performance. The entire door opening sealing strip is made of extruded variable cross-section foam tube body 300 through extrusion orifice, which not only facilitates installation, but also thickens the foam tube 302 section below the waistline, thereby increasing the product's compressive load and solving the problem of water leakage under vehicle wading conditions. The entire door opening sealing strip improves the pull-out force through anti-detachment protrusions 900, anti-detachment lip 1000 and abutment lip 1001, thereby preventing the sealing strip from falling off the door opening stop.

[0020] The specific embodiments described herein are merely illustrative examples of the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications to the described specific embodiments or adopt similar methods to replace them, but without departing from the scope defined by the spirit of this utility model.
