Technical Field

[0001] The present invention relates to the technical field of vehicles, and in particular to a water-resistant sealing structure and a vehicle. Background Art

[0002] When the vehicle is wading, in order to ensure the vehicle's wading performance, the compression load of the door frame sealing strip is defined to be larger, resulting in a larger static closing force of the door.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present invention.

[0025] The existing solution for the wading sealing structure is that the entire circle of the door frame sealing strip has a single cross-section. To obtain higher sealing performance, the sealing reaction force of the door frame sealing strip is made twice or even more than the conventional design, resulting in a very large static door closing force for the entire vehicle door, and customers need to use a great deal of effort to close the door to the locked position. Due to the above situation, this application proposes an improved wading sealing structure.

[0026] As Figures 1 to 3 shown in a specific embodiment of the wading sealing structure, it includes: a first sealing part and a second sealing part. The wading sealing structure described in this application is applicable to vehicles for deep wading. The vehicle can be an automobile.

[0027] As Figure 2 and Figure 3As shown, the first sealing part is arranged at a position corresponding to the non-wading area on the door opening; the first sealing part is composed of a first clamping member 1 and a first sealing bubble tube 2 which are connected; the first clamping member 1 is suitable for clamping and installing on the edge of the door opening. The second sealing part is connected to the first sealing part or the first sealing part and the second sealing part are an integral structure. When the first sealing part and the second sealing part are an integral structure, the first sealing part and the second sealing part are integrally extruded variable cross-section structures. The second sealing part is arranged at a position corresponding to the wading area on the door opening; the second sealing part is composed of a second clamping member 3 and a second sealing bubble tube 4 which are connected; the second clamping member 3 is suitable for clamping and installing on the edge of the door opening; and an elastic block 5 is arranged outside the second clamping member 3, and the elastic block 5 is suitable for increasing the sealing force between the door and the door opening. The wading depth of the wading area can be 500 mm, 800 mm or 1000 mm, etc.; the door opening is a door frame that matches the door. The elastic block 5 can be a raised strip, and the elastic block 5 is an extra piece extruded when the second clamping member 3 is manufactured by extrusion. The added elastic block 5 is equivalent to a water-resistant sealing structure that adopts a variable cross-section structure. The door frame located above the water-resistant surface uses a first sealing portion that does not contain the elastic block 5, and the door frame below the water-resistant surface uses a second sealing strip containing the elastic block 5 to increase the compression load. The water-resistant sealing structure as a whole reduces the sealing reaction force at the door of the entire vehicle as much as possible, and uses a variable cross-section structure to reduce the static door closing force, that is, the second sealing portion located in the water-resistant area uses a variable cross-section structure with an added elastic block 5 to increase the sealing reaction force, and the first sealing portion in the non-water-resistant area uses a conventional cross-section with a smaller sealing reaction force, which reduces the static closing force of the door as much as possible, significantly improving the customer's experience.

[0028] Specifically, Figure 2 and Figure 3 As shown, the first clamping member 1 and the second clamping member 3 are both U-shaped, and a U-shaped frame 6 is provided inside the first clamping member 1 and the second clamping member 3.
