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 sealing structure of a skateboard chassis. Background Art

[0002] As environmental pollution becomes increasingly serious, fossil fuels, as non-renewable energy sources, are continuously decreasing. It has become an irreversible trend for electric vehicles with no pollution and zero emissions 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 efficiency, 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 invent a new sealing structure for a skateboard chassis for sealing between the skateboard chassis and the body. This seal has the characteristics of low cost, convenient installation, and the ability to repeatedly disassemble and assemble the skateboard chassis without losing the sealing performance.

[0005] To achieve the above purpose, the technical solution of the present invention is: A sealing structure for a body and a skateboard chassis, comprising:

[0006] A body, arranged at the upper part of the vehicle, capable of providing installation support for the interior trim and providing 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 on the skateboard chassis, with a sealing lip or bubble provided on the skateboard chassis sealing strip, elastically contacting the body; a protruding feature is provided on the skateboard chassis sealing strip, and a recessed feature is provided on the skateboard chassis. The skateboard chassis sealing strip is fixedly connected to the skateboard chassis by embedding the protruding feature into the groove feature of the skateboard chassis.

[0009] Further, the body has a sealing surface for providing a sealing surface for the skateboard chassis sealing strip and sealing the gap A between the body and the skateboard chassis.

[0010] Further, the body has an inclined surface that slopes downward and is connected to the matching surface of the body, playing a role in blocking water and preventing water from directly impacting the sealing surface.

[0011] Furthermore, the skateboard chassis has a mounting surface that is connected and matched with a matching surface of the vehicle body.

[0012] 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, so as to seal the gap A between the vehicle body and the skateboard chassis.

[0013] 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.

[0014] Furthermore, two tooth-shaped features are arranged on the convex features of the skateboard chassis sealing strip, and the tooth-shaped features are connected with the concave features in the skateboard chassis by interference fit.

[0015] 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, thereby ensuring dimensional stability.

[0016] Furthermore, the core material is metal or nylon

[0017] The beneficial effects of the present invention are:

[0018] The sealing structure of the present invention adopts a skateboard chassis sealing strip to be clamped on the skateboard chassis, the skateboard chassis is connected to the vehicle body, and the first sealing lip edge and the second sealing lip edge of the skateboard chassis sealing strip are in elastic contact with the vehicle body sealing surface to play a sealing role.

[0019] 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

[0023] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0024] like Figure 1 Shown 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 .

[0025] like Figure 3As shown, a metal wire 4 is provided in the sealing strip 2 of the skateboard chassis to prevent the sealing strip from shrinking in the length direction and increase the length stability of the sealing strip. A raised feature 2e is provided at the bottom of the skateboard chassis sealing strip 2, and the raised feature 2e is embedded in the recessed feature 3b of the skateboard chassis 3. The raised feature 2e is provided with tooth-shaped features 2ea and 2eb. The tooth-shaped features 2ea and 2eb and the recessed feature 3b are interference-fitted to realize the connection between the skateboard chassis sealing strip 2 and the skateboard chassis 3. The skateboard chassis sealing strip 2 is provided with raised features 2c and 2d, which are in elastic contact with the mounting surfaces 3c and 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. The vehicle body 1 and the skateboard chassis 3 are connected by fasteners so that the matching surface 1c and the mounting surface 3a are opposite. A sealing surface 1a is provided on the vehicle body 1, and a sealing gap A of 4 to 15 mm is provided between the vehicle body sealing surface 1a and the mounting surfaces 3c and 3d of the skateboard chassis sealing strip. The body sealing surface 1a and the first sealing lip 2a and the second sealing lip 2b of the skateboard chassis sealing strip are in elastic contact, sealing the sealing gap A between the body 1 and the skateboard chassis. A cavity B is provided between the first sealing lip 2a and the second sealing lip 2b, and the cavity B can guide the water that has passed over the first sealing lip 2a. The body 1 has an inclined surface 1b, which is inclined downward and connected to the body matching surface 1c, playing a water-blocking role, preventing the water that intrudes from between the matching surface 1c and the mounting surface 3a from directly impacting the sealing surface 1a, and relieving the water pressure on the sealing strip.
