Description

Technical Field

[0001] This invention relates to automotive sunroofs, and more particularly to a waterproof structure for automotive sunroofs. Background Technology

[0002] Modern car sunroofs are typically sealed to the car body using rubber strips and body panels. In dual-glass sunroofs, the front window is movable while the rear window is fixed to the window frame. Therefore, the sealing structure between the front window and the car body differs from that between the rear window and the car body. Each rubber strip and its mating component forms an overlap. When the front window closes against the rear window, and the window frame is closed, each overlap is sealed by the elastic force of the rubber strip. However, the intersection of these overlaps at the junction of the front and rear windows cannot reliably withstand the elastic force of the rubber strip, making them prone to water ingress. Summary of the Invention

[0003] The purpose of this invention is to provide a waterproof structure for automotive sunroofs to prevent leakage at the joints where the front and rear windows meet.

[0004] The waterproof structure for a car sunroof of the present invention includes a front window assembly, a rear window assembly, and a pair of window side frame strips. The front window assembly has a front glass panel and a front frame, the front frame being disposed around the periphery of the front glass panel, and the front window assembly having a rear end portion. The rear window assembly has a rear glass panel and a rear weatherstripping, the rear window assembly having a pair of side edges and a front end portion connecting the pair of side edges, the rear weatherstripping being wrapped around the pair of side edges and the front end portion. Window side frame strips are respectively disposed adjacent to each side edge of the rear window assembly, and each window side frame strip has a protrusion extending towards the rear end portion. A pair of flanges extend from both ends of the rear end portion, the flanges being respectively disposed at the two ends of the front end portion of the rear window assembly. When the rear end portion approaches the front end portion, the front frame abuts against the rear weatherstripping, and each flange respectively covers the rear weatherstripping and each protrusion.

[0005] In one embodiment of the present invention, the rear window assembly includes a rear frame that is fitted around the periphery of the rear glass panel, and a rear weatherstripping is assembled onto the rear frame. The rear weatherstripping is held between the front frame and the rear frame.

[0006] In one embodiment of the present invention, each flange covers the rear end of the front window assembly and the intersection of each side edge of the rear window assembly.

[0007] In one embodiment of the present invention, the rear waterproof strip is in the shape of a hollow tube.

[0008] In one embodiment of the present invention, the front window assembly has a front weatherstripping that wraps around the front frame and exposes the rear end of the front window assembly.

[0009] In one embodiment of the present invention, the front waterproof strip is assembled onto the front frame. The front waterproof strip is in the shape of a hollow tube.

[0010] In one embodiment of the present invention, the pair of flanges are disposed at both ends of the rear end portion of the front window assembly.

[0011] The waterproof structure for a car sunroof of the present invention, when the front window assembly and the rear window assembly are closed together, each flange can cover the rear end of the front window assembly and the intersection of the seams of each side edge of the rear window assembly to prevent leakage.

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0022] See Figures 1 to 6 An embodiment of the present invention provides a waterproof structure for an automotive sunroof, comprising a front window assembly 100, a rear window assembly 200, and a pair of window side frame strips 300. The waterproof structure for the automotive sunroof of the present invention is disposed within a window 11 on the roof 10 of the vehicle. The window 11 is generally rectangular. The front window assembly 100 is movably disposed within the window 11, while the rear window assembly 200 is fixedly disposed within the window 11. The rear window assembly 200 covers half of the window 11, and the front window assembly 100 can be brought together with the rear window assembly 200 to cover the other half of the window 11 and close the window 11. Specifically, both the front window assembly 100 and the rear window assembly 200 are generally rectangular. Relative to the travel distance of the front window assembly 100, the front window assembly 100 has a rear end portion 101, and the rear window assembly 200 has a front end portion 201. The rear end portion 101 of the front window assembly 100 and the front end portion 201 of the rear window assembly 200 are matched to form a closed shape. Partial outlines of the front window assembly 100 and the rear window assembly 200 are matched with the outline of the inner edge of the window 11. Specifically, the roof 10 generally includes a roof panel 12 and a reinforcing frame 13. The window 11 is formed on the roof panel 12, and the reinforcing frame 13 is disposed inside the roof panel 12 corresponding to the window 11 for mounting the front window assembly 100 and the rear window assembly 200. The reinforcing frame 13 can be directly welded to the roof panel 12.

[0023] See Figure 1 and Figures 7 to 9 The front window component 100 can move upward and away from the rear window component 200 to open the window 11.

[0024] See Figures 1 to 3 and Figure 7 The front window assembly 100 has a front glass panel 110 and a front frame 120, and in this embodiment, the front window assembly 100 further includes a front weatherstripping 130. The front glass panel 110 is generally rectangular, the front frame 120 is a rectangular frame made of a rigid plastic material (e.g., polyurethane / PU, but the invention is not limited thereto), the front frame 120 is fitted around the periphery of the glass panel, and the front weatherstripping 130 is a hollow tube made of an elastic material (e.g., silicone or rubber, but the invention is not limited thereto) and is assembled to the outer edge of the front frame 120. See also... Figure 3 and Figure 4 Specifically, the front weatherstripping 130 wraps around the front frame 120, and the front weatherstripping 130 does not extend to the rear end 101 of the front window assembly 100, thus exposing the front frame 120 at the rear end 101 of the front window assembly 100. See also Figure 1 , Figure 5 and Figure 6When the front window assembly 100 approaches the rear window assembly 200, the rear end 101 of the front window assembly 100 can abut against the front end 201 of the rear window assembly 200.

[0025] See Figures 7 to 9 The rear window assembly 200 has a rear glass panel 210 and a rear weatherstripping 230. In this embodiment, the rear window assembly 200 also includes a rear frame 220, which is a rectangular frame made of a rigid plastic material (e.g., polyurethane / PU, but the invention is not limited thereto). The rear window assembly 200 has a pair of side edges 202, and the front end portion 201 of the rear window assembly 200 is connected between the pair of side edges 202. The rear frame 220 is fitted around the periphery of the rear glass panel 210. The rear weatherstripping 230 is a hollow tube made of an elastic material (e.g., silicone or rubber, but the invention is not limited thereto), and the rear weatherstripping 230 is assembled to the outer edge of the rear frame 220. The rear weatherstripping 230 at least surrounds the side edges 202 and the front end portion 201 of the rear window assembly 200. See also Figure 1 , Figure 5 and Figure 6 When the front end 201 of the rear window assembly 200 approaches the rear end 101 of the front window assembly 100, and the front frame 120 presses against the rear weatherstripping 230, the rear weatherstripping 230 is clamped and compressed by the front frame 120 and the rear frame 220 and sealed.

[0026] See Figures 1 to 2 and Figure 7 The window side frame strips 300 are made of a rigid plastic material (e.g., polyurethane / PU, but the invention is not limited thereto), and are disposed opposite to each side edge 202 of the rear window assembly 200 on the inner edge of the window 11. The pair of window side frame strips 300 are respectively attached to each side edge 202 of the rear window assembly 200. See also... Figure 5 and Figure 8 Each window side frame strip 300 has an end 301 disposed toward the front window assembly 100, and each window side frame strip 300 has a protrusion 310, and each protrusion 310 extends from the end 301 of its respective window side frame strip toward the rear end 101 of the front window assembly 100. Furthermore, as... Figures 1 to 2 and Figure 5 As shown, when the current window assembly 100 is close to the rear window assembly 200, the ends 301 of each window side frame strip 300 abut against the front frame 120 with protrusions 310.

[0027] See Figure 3 and Figure 4 The front frame 120 extends a pair of flanges 121, which are disposed at both ends of the rear end 101 of the front window assembly 100, corresponding to the two ends of the front end portion 201 of the rear window assembly 200. (See also...) Figures 1 to 2and Figures 5 to 6 When the front window assembly 100 and the rear window assembly 200 are closed together, the pair of flanges 121 respectively cover the front frame 120, the rear weatherstripping 230, and the protrusions 310 of the corresponding window side frame strips 300. When the front window assembly 100 and the rear window assembly 200 are closed together, a joint is formed between the rear weatherstripping 230 and its respective mating structures (front window assembly 100, window side frame strips 300), and each flange 121 can cover the intersection of the joints of the rear end 101 of the front window assembly 100 and the side edges 202 of the rear window assembly 200 to prevent leakage.
