[0025] Please refer to Figures 1 to 3 , Figure 1 This is a structural diagram of an embodiment of a sealing strip of the present application. Figure 2 This is a schematic structural diagram of a vehicle embodiment of the present application. Figure 3 yes Figure 2 A partially enlarged schematic diagram. One aspect of the present application provides a sealing strip 1 for contacting and sealing a vehicle door, the sealing strip 1 comprising a connecting portion 11 and a sealing bubble tube 12; specifically, the connecting portion 11 is provided with a plate-shaped connecting surface 111, the connecting surface 111 is used to connect to the vehicle body, which can improve stability, and the vehicle body is connected only through the connecting surface 111, which can simplify the structure, so that the sealing strip 1 can be automatically produced. The sealing bubble tube 12 is used to contact the vehicle door, and a two-way valve 121 connected to the outside is provided on the sealing bubble tube 12. An inflatable liner 122 connected to the two-way valve 121 is also provided inside the sealing bubble tube 12. The size of the inflatable liner 122 can be changed by inflating or deflating the inflatable liner 122, thereby changing the air pressure in the sealing bubble tube 12 and adjusting the sealing force of the sealing bubble tube 12 on the vehicle door, thereby improving the sealing effect and increasing the reliability of the seal.

[0026] When in use, the sealing strip 1 of the present application has an active sealing function, specifically, the inflatable inner liner 122 can be automatically inflated or deflated according to outdoor conditions, so that the sealing bubble tube 12 can automatically switch to various sealing forms according to the inflation amount, and adjust the sealing force of the sealing bubble tube 12 on the car door, thereby improving the sealing effect and increasing the reliability of the sealing.

[0027] Furthermore, the connecting surface 111 is in a plate shape, which increases the contact area with the vehicle body and improves the stability and reliability of the connection.

[0028] In one embodiment of the present application, an adhesive layer 1111 is provided on the connection surface 111, and the adhesive layer 1111 can play a role of adhesive connection, that is, the connection surface 111 can be adhesively connected to the vehicle body through the adhesive layer 1111 to improve stability.

[0029] In a specific embodiment, 3M tape may also be provided on the connecting surface 111, and the connecting surface 111 is connected and fixed to the vehicle body by the 3M tape. Since 3M tape has strong sealing ability, the sealing effect between the connecting part 11 and the vehicle body can be improved, thereby improving or avoiding water leakage and air leakage problems on the connecting surface 111.

[0030] Furthermore, since the sealing strip 1 can be connected and fixed to the vehicle body only by bonding the connecting surface 111 to the vehicle body, the plate-shaped connecting surface 111 simplifies the structure of the sealing strip 1, reduces the manufacturing difficulty and weight of the sealing strip 1, and thus improves economic benefits.

[0031] In one embodiment of the present application, the connecting portion 11 includes a connecting plate 112 and a connecting block 113 protruding from one end of the connecting plate 112. Specifically, a connecting surface 111 is provided on the side of the connecting plate 112 facing the connecting block 113, for connection to the vehicle body. The sealing bubble tube 12 is connected to a first side 1131 of the connecting block 113 facing away from the connecting plate 112, for contact with the tailgate 2 of the vehicle 10.

[0032] Since the sealing strip 1 can be connected and fixed to the vehicle body through the connecting surface 111 of the connecting plate 112, the structure of the connecting block 113 can be simplified in design, thereby reducing manufacturing difficulty and weight, and improving economic benefits. In a specific embodiment, the combination of the connecting block 113 and the connecting plate 112 can be an L-shaped structure.

[0033] In one embodiment of the present application, the sealing strip 1 also includes a skeleton 13, which is buried in the connecting plate 112 and the connecting block 113, and is used to support and determine the basic shape of the sealing strip 1, which can effectively prevent the sealing strip 1 from being easily deformed after long-term use.

[0034] In a specific embodiment, the skeleton 13 may also be in an L-shaped structure to facilitate supporting the connection block 113 and the connection plate 112 , and make the connection block 113 and the connection plate 112 in an L-shaped structure, thereby simplifying the structure and reducing costs.

[0035] In one embodiment of the present application, the two-way valve 121 passes through the connecting block 113 and faces the second side surface 1132 of the connecting plate 112 , so that the inflatable liner 122 can communicate with the connecting block 113 .

[0036] Specifically, if Figure 2 As shown, the two-way valve 121 can be connected to the air pipe 7 for ventilation. The two-way valve 121 and the air pipe 7 cooperate to penetrate the connecting block 113 so that the inflatable liner 122 is connected to the outside world, thereby enabling the inflatable liner 122 to be inflated and deflated.

[0037] In one embodiment of the present application, opposite sides of the connection block 113 are respectively provided with a first sealing tongue 1133 extending along the connection plate 112 toward the connection block 113 and a second sealing tongue 1134 extending along the connection plate 112 away from the connection block 113.

[0038] Specifically, if Figure 2 As shown, the first sealing tongue 1133 and the second sealing tongue 1134 are both used to connect with the vehicle body and play a role in improving the sealing performance.

[0039] Furthermore, a connecting bubble tube 14 is provided at the position where the first sealing tongue 1133 and the second sealing tongue 1134 are connected to the vehicle body for sealing connection with the vehicle body. A connecting bubble tube 14 is also provided at one end of the connecting plate 112 facing away from the connecting block 113 for sealing connection with the vehicle body to improve the sealing effect.

[0040] In a specific embodiment, the sealing bubble tube 12 and the connecting bubble tube 14 can both use EPDM foam material (Ethylene Propylene Diene Monomer, EPDM). EPDM is a polymer compound copolymerized by ethylene, propylene and a small amount of non-conjugated dienes, and has excellent aging resistance. The bubble tube made of EPDM foam material has the beneficial effects of light bulk density, high elastic strength, no water absorption, and wear resistance, thereby improving the sealing effect, waterproofness and durability of the sealing strip 1.

[0041] The sealing strip 1 of the embodiment of the present application is connected and fixed to the vehicle body via the connecting surface 111, which simplifies the structure, improves stability, and improves or avoids problems such as poor durability over a long period of time. A 3M tape is provided on the connecting surface 111, and the 3M tape is bonded to the vehicle body to further improve the sealing effect, and improve or avoid problems such as water leakage and air leakage on the connecting surface 111. The air pressure of the sealing strip 1 can be adjusted by the inflatable liner 122, thereby adjusting the sealing performance between the sealing strip 1 and the vehicle door, so that there is sufficient pressure between the vehicle door and the sealing bubble tube 12, and problems such as air leakage and water leakage can be improved or avoided. Furthermore, by sealing the vehicle door with the sealing strip 1 of the embodiment of the present application, the vehicle door can also be made to have the ability to wade through water.

[0042] Please continue to combine Figure 2 and Figure 3On the other hand, the present application also provides a vehicle 10, which includes a tailgate 2, a rear panel assembly 3, and the aforementioned sealing strip 1. Specifically, the sealing strip 1 is connected and fixed to the first end 31 of the rear panel assembly 3 via a connecting surface 111. The sealing strip 1 contacts the tailgate 2 via a sealing bubble tube 12, thereby achieving a sealing effect on the tailgate 2. By providing the sealing strip 1 at the rear panel assembly 3 of the vehicle 10, the tailgate 2 can contact the sealing strip 1 when closed, thereby preventing water leakage from the tailgate 2 and ensuring the sealing effect of the tailgate 2. This effectively ensures the safety and reliability of items placed in the trunk of the vehicle 10, improves the safety and reliability of the vehicle 10, and is conducive to market promotion and application.

[0043] Furthermore, when the sealing strip 1 contacts the tailgate 2 , the sealing protrusion 123 abuts against the tailgate 2 , and the gap 124 , the sealing bubble tube 12 , and the tailgate 2 form a sealed space 4 .

[0044] like Figure 2 and Figure 3 As shown, in a specific embodiment, two sealing protrusions 123 are provided on the sealing bubble tube 12. The hardness of the sealing protrusion 123 is greater than the hardness of the surrounding bubble tubes, so that point contact can be formed when it contacts the tailgate 2, so that the gap 124 between the corresponding two sealing protrusions 123 can be enclosed with the tailgate 2 to form a closed space 4. This closed space 4 can serve as a second line of defense to prevent external dust, water, wind and other substances from entering the vehicle, thereby enhancing the waterproofness of the sealing strip 1. It should be noted that in the embodiment of the present application, the tailgate 2 may include a tailgate inner panel 21 and a tailgate outer panel 22, with both sealing protrusions 123 in contact with the tailgate inner panel 21. Specifically, the sealing protrusion 123 near the tailgate outer panel 22 contacts the tailgate inner panel 21, forming a first line of defense against water inflow. During use, water flows from the tailgate outer panel 22 into the tailgate inner panel 21. After the first line of defense blocks most of the water, a small amount of water may still pass through the contact point between the sealing protrusion 123 and the tailgate inner panel 21. The enclosed space 4, acting as a second line of defense, can retain this water, thereby achieving a waterproofing effect. In another specific embodiment, more than two sealing protrusions 123 may be provided, such as three, four, five, or six, to increase the number of enclosed spaces 4 and thereby improve waterproofing performance.

[0045] Furthermore, the rear enclosure assembly 3 includes a rear enclosure inner panel 33 and a rear enclosure outer panel 34, which are welded together at the first end 31 and the second end 32 respectively, and the connecting surface 111 is connected and fixed to the portion of the rear enclosure outer panel 34 at the first end 31; the first end 31 is provided with a welding gap, and the rear enclosure inner panel 33 and the rear enclosure outer panel 34 are enclosed between the first end 31 and the second end 32 to form an accommodating space 35; the vehicle 10 also includes an air pump 5 and a controller 6, and the air pump 5 and the controller 6 are located in the accommodating space 35, and the air pump 5 is connected to the two-way valve 121 through the air pipe 7 through the welding gap, and the controller 6 controls the air pump 5 to inflate or deflate the inflatable liner 122.

[0046] At the first end 31, the sealing strip 1 is bonded to the rear outer panel 34 via the connecting surface 111. This not only improves the stability of the sealing strip 1 during installation, but also prevents water from flowing along the rear outer panel 34 into the connection between the sealing strip 1 and the rear outer panel 34, thereby improving waterproof performance. The connecting bubble tube 14 on the connecting plate 112 also contacts the rear outer panel 34, further improving sealing.

[0047] Along the width direction of the vehicle body 10, a welding gap is left at the welding position of the rear outer panel 34 and the rear inner panel 33 at the first end 31. It can be used for the air supply pipe 7 to pass through, so that the inflatable liner 122 can be connected to the air pump 5 to achieve inflation and deflation of the inflatable liner 122. The controller 6 can be an intelligent controller 6. The intelligent controller 6 can determine whether inflation or deflation is needed based on external conditions. By electrically connecting the intelligent controller 6 to the air pump 5, the air pump 5 can automatically inflate or deflate the inflatable liner 122 according to the required air pressure, thereby improving convenience and ensuring sufficient air pressure between the tailgate 2 and the sealing strip 1, thereby improving waterproof performance. Through the above structure, the sealing performance between the tailgate 2 and the vehicle body is effectively improved, and the tailgate 2 can even be made water-resistant.

[0048] Furthermore, the vehicle 10 also includes a bumper 8 and a tailgate trim 9. The bumper 8 is located on the side of the rear outer panel 34 facing the tailgate 2, and the bumper 8 is sealed to the first sealing tongue 1133 of the sealing strip 1; the tailgate trim 9 is located on the side of the rear inner panel 33 facing the tailgate 2, and the tailgate trim 9 is connected to the second sealing tongue 1134 of the sealing strip 1.

[0049] The bumper 8 is connected to the first sealing tongue 1133, which not only improves sealing performance but also prevents the bumper 8 from being abruptly positioned between the tailgate inner panel 21 and the rear panel 34, thereby maintaining a neat and aesthetically pleasing rear end structure. The tailgate trim 9 is connected to the second sealing tongue 1134, eliminating the need for additional structures or components for connecting the tailgate trim 9. This simplifies the vehicle structure and improves its appearance. In the vehicle 10 of the present embodiment, the sealing strip 1 integrates the tailgate trim 9, bumper 8, and rear panel assembly 3, simplifying the structure, reducing costs, and enhancing the appearance of the vehicle.
