Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, specifically to a water-sealing structure and a vehicle. Background Technology

[0002] When a vehicle is wading through water, in order to ensure the vehicle's wading performance, the compressive load of the door frame sealing strip is increased, which leads to an increase in the static closing force of the door.

[0003] The demand for deep wading capabilities for automobiles is increasing, from the conventional 500 mm to 800 mm, and even reaching 1000 mm. To meet this demand, the sealing force of the door opening seals is generally increased to achieve waterproofing. However, this method results in greater closing force on the doors, significantly worsening the closing experience. Utility Model Content

[0004] In view of this, the present invention provides a water-resistant sealing structure to solve the problem that the existing method of increasing the sealing force of the sealing strip at the door opening results in a large closing force for the car door and a significantly worse closing experience.

Beneficial effect: This application adopts the above technical solution to prevent the first and second clamping members from dislodging from the edge of the door opening.

[0010] Optionally, sealant is applied to the inner sides of the first and second clamping members. Beneficial effect: This application employs the above technical solution to prevent water from flowing into the driver's cab from the sheet metal stop area.

Detailed Implementation

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

[0025] Existing water-sealing structures use a single cross-section for the entire door frame sealing strip. To achieve higher sealing performance, the sealing reaction force of the door frame sealing strip is made twice or more than that of conventional designs. This results in a very high static closing force for the entire door, requiring customers to exert considerable force to close the door to the locked position. Due to these limitations, this application proposes an improved water-sealing structure.

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

[0027] like Figure 2 and Figure 3As shown, the first sealing part is positioned on the door opening corresponding to the non-wading area; the first sealing part consists of a first clamping member 1 and a first sealing bubble tube 2 connected together; the first clamping member 1 is adapted to clamp and install 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 positioned on the door opening corresponding to the wading area; the second sealing part consists of a second clamping member 3 and a second sealing bubble tube 4 connected together; the second clamping member 3 is adapted to clamp and install on the edge of the door opening; and an elastic block 5 is provided on the outside of the second clamping member 3, the elastic block 5 being adapted to increase 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 the door frame that mates with the door. The aforementioned elastic block 5 can be a raised strip. Elastic block 5 is an additional piece extruded during the extrusion manufacturing of the second clamping part 3. The added elastic block 5 is equivalent to a variable cross-section structure in the wading sealing structure. The door frame above the wading surface uses a first sealing part without elastic block 5, while the door frame below the wading surface uses a second sealing strip containing elastic block 5, increasing the compressive load. The wading sealing structure as a whole minimizes the sealing reaction force at the vehicle door. The variable cross-section structure reduces the static closing force; specifically, the second sealing part in the wading area uses a variable cross-section structure with added elastic block 5 to improve the sealing reaction force, while the first sealing part in the non-wading area uses a conventional cross-section with lower sealing reaction force, minimizing the static closing force of the door and significantly improving the customer's user experience.

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

[0034] Furthermore, such as Figure 1 and Figure 3 As shown, the elastic block 5 is located outside the first clamping member 1 or the second clamping member 3, within the closed area enclosed by the elastic member 12 and the extension 11 of the first sealing bubble tube 2 or the second sealing bubble tube 4.

[0035] Specifically, both the first sealing bubble tube 2 and the second sealing bubble tube 4 are made of sponge rubber.

[0036] like Figure 1 and Figure 4 As shown, this utility model also provides a vehicle, including: the aforementioned wading sealing structure.

[0037] The vehicle described in this application may be an automobile. The vehicle described in this application has a sealing strip on the edge of its door. The sealing strip includes a U-shaped member 13 and a third sealing bubble tube 14 connected together.

[0038] One outer side of the U-shaped component 13 is continuously bonded to the edge of the car door using tape 15; a third sealing bubble tube 14 is connected to the other outer side of the U-shaped component 13; the outer side of the third sealing bubble tube 14 has an arc-shaped protrusion. Nylon thread 8 is also embedded along the length of the U-shaped component 13. The car door is a sheet metal door; the third sealing bubble tube 14 is a sponge-like component; the U-shaped component 13 is a solid rubber component. The tape 15 is 3M tape. Pull-up knots are provided on the first sealing bubble tube 2, the second sealing bubble tube 4, and the third sealing bubble tube 14.
