Description

Technical Field

[0001] The present invention relates to a sealing structure between a skateboard chassis and a body of an electric vehicle, and in particular to a skateboard chassis sealing structure. Background Art

[0002] As environmental pollution becomes increasingly serious, fossil fuels, as non-renewable energy sources, are constantly decreasing. It has become an irreversible trend for pollution-free and zero-emission electric vehicles to replace traditional fuel vehicles. Currently, mainstream electric vehicles still adopt traditional chassis designs, resulting in increasingly obvious shortcomings such as high vehicle costs, heavy weights, low cruising ranges, low space efficiencies, and long development cycles.

[0003] With the development of electric vehicles, the competition among vehicle manufacturers has become increasingly fierce. A skateboard chassis with low cost, light weight, high cruising range, high space efficiency, and short development cycle will become the trend of electric vehicle chassis development. Along with the emergence of this new type of chassis, how to achieve the sealing between the skateboard chassis and the body has become a new industry problem. Summary of the Invention

[0004] The purpose of the present invention is to propose a new skateboard chassis sealing structure for sealing between the skateboard chassis and the body. This seal has the characteristics of low cost, convenient installation, and can achieve repeated disassembly and assembly of the skateboard chassis without loss of sealing performance.

[0005] To achieve the above purpose, the technical solution of the present invention is: a skateboard chassis sealing structure, including:

[0006] A body, placed at the upper part of the vehicle, used to provide installation support for the interior trim and provide a accommodation space for passengers or goods;

[0007] A skateboard chassis, arranged at the lower part of the vehicle, connected to the body, and playing a load-bearing role for the body;

[0008] A skateboard chassis sealing strip, arranged between the skateboard chassis and the body, used for sealing between the skateboard chassis and the body;

[0009] A double-sided tape, arranged between the skateboard chassis and the skateboard chassis sealing strip, used for connecting the skateboard chassis and the skateboard chassis sealing strip.

[0010] Further, the body has a body sealing surface and a body mating surface. Among them, the body sealing surface is used to provide a sealing surface for the skateboard chassis sealing strip and seal the gap A between the body and the skateboard chassis.

[0011] Further, the body has an inclined surface, which is inclined downward and connected to the body mating surface, playing a role in blocking water and preventing water from directly impacting the body sealing surface.

[0012] Furthermore, the skateboard chassis has a mounting surface, and the mounting surface is cooperatively connected with the matching surface of the vehicle body.

[0013] Furthermore, the skateboard chassis sealing strip is bonded to the skateboard chassis mounting surface by double-sided adhesive tape.

[0014] Furthermore, the skateboard chassis is provided with two raised features, and a skateboard chassis sealing strip installation surface is provided between the two raised features, wherein the two raised features of the skateboard chassis serve as installation references for the skateboard chassis sealing strip, limiting the outward position of the skateboard chassis sealing strip in the vehicle.

[0015] Furthermore, the skateboard chassis sealing strip is provided with two raised features, and the two raised features are in elastic contact with the mounting surface of the skateboard chassis sealing strip to play a sealing role.

[0016] Furthermore, the skateboard chassis sealing strip has a first sealing lip and a second sealing lip, and the first sealing lip and the second sealing lip are elastically in contact with the sealing surface of the vehicle body respectively, and are used to seal the gap A between the vehicle body and the skateboard chassis.

[0017] Furthermore, a cavity B is provided between the first sealing lip and the second sealing lip, and the cavity B can discharge water that flows over the first sealing lip.

[0018] Furthermore, a core material is arranged inside the skateboard chassis sealing strip to prevent the skateboard chassis sealing strip from shrinking in the length direction and ensure dimensional stability.

[0019] The beneficial effects of the present invention are:

[0020] The sealing structure of the present invention uses a skateboard chassis sealing strip bonded to the skateboard chassis by tape, the skateboard chassis is connected to the vehicle body, and the first sealing lip and the second sealing lip of the skateboard chassis sealing strip are in elastic contact with the vehicle body sealing surface to play a sealing role.

[0021] The sealing structure has the characteristics of low cost, convenient installation, and can realize repeated disassembly and assembly of the skateboard chassis without losing the sealing performance. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0026] like Figure 1Shown is a perspective view of the entire vehicle and the location of the schematic section AA. Figure 2 The figure shows an exploded view of the whole vehicle, showing a vehicle body 1 , a skateboard chassis 3 , and a skateboard sealing strip 2 arranged between the vehicle body 1 and the skateboard chassis 3 .

[0027] like Figure 3 As shown, a metal wire 4 is provided inside the skateboard chassis sealing strip 2 to prevent the sealing strip from shrinking in the length direction and increase the length stability of the sealing strip. A double-sided tape 5 is attached to the mounting surface 2e of the skateboard chassis sealing strip, and the double-sided tape 5 is attached to the mounting surface 3d of the skateboard chassis sealing strip. The mounting surface 3d of the skateboard chassis sealing strip is arranged between the raised features 3b and 3c of the skateboard chassis 3. The raised features 3b and 3c of the skateboard chassis 3 serve as the mounting reference of the skateboard chassis sealing strip 2 to limit the outward position of the skateboard chassis sealing strip 2 in the vehicle. The skateboard chassis sealing strip 2 is provided with raised features 2c and 2d, and the raised features 2c and 2d are in elastic contact with the mounting surface 3d of the skateboard chassis sealing strip to play a sealing role. The vehicle body 1 has a matching surface 1c, and the skateboard chassis 3 is provided with a mounting surface 3a.
