The waterproof spoiler assembly disclosed in this invention is arranged above the rear of the vehicle roof. Through the cooperation of the upper sealing strip 1 and the lower sealing strip 2, rainwater from the vehicle roof can be guided to both sides of the roof during subsequent use and flow to the ground through the water channels on both sides of the roof. This reduces or prevents most of the water from entering the cavity formed by the spoiler and the rear of the roof, and prevents rainwater from accumulating at the bottom of the spoiler assembly 1-1 and invading the tailgate sealing strip, which would cause the sealing strip to fail.

[0074] The spoiler assembly 1-1 disclosed in this invention is mainly applicable to rugged SUV models.

[0075] In actual installation, the aforementioned spoiler assembly 1-1 is located at the top of the rear of the vehicle body. Specifically, the vehicle body has a recessed groove at the location where the spoiler assembly is installed.

[0112] Meanwhile, in this invention, a drainage hole 13 is designed at the lowest point of the bottom of the outer plate 4 of the spoiler to prevent water accumulation between the inner and outer plates of the spoiler.

[0113] Secondly, the top and bottom of the outer panel 4 and the inner panel 3 of the spoiler are also designed with adhesive surfaces. The middle part is designed with a spoiler decorative panel installation structure, and the top camera wiring harness through hole is designed in the center. A water-guiding structure combining water-blocking ribs 18 and sponge strips is used to prevent rainwater from directly entering this hole.

[0114] Meanwhile, in this invention, the top of the outer plate 4 of the spoiler is required to be provided with an outer plate slot 21, which is used to cooperate with the snap-fit ​​plate 29 on the body of the decorative outer plate; at the same time, a support rib 22 is provided in the outer plate slot 21 to fix the top of the outer plate of the spoiler decorative component.

[0115] The snap-fit ​​plate 29 is provided with snap-fit ​​edge support ribs 30.

[0116] Meanwhile, an outer plate support rib 17 is provided on the outer plate of the spoiler; the outer plate support rib is used to ensure the strength of the outer plate of the spoiler.

[0117] Meanwhile, in this invention, the decorative component is connected to the outer plate 4 and the inner plate 3 of the spoiler. To avoid interference, a fastening hole is provided on the inner plate 3 of the spoiler, and the aforementioned clearance hole 4-1 is provided on the outer plate 4 of the spoiler. To prevent rainwater that has entered the top of the outer plate 7 of the spoiler decorative component and the cavity of the outer plate 4 of the spoiler from flowing directly into the gap between the two, a sponge strip is designed at the joint between the middle of the inner plate 6 of the spoiler decorative component and the outer plate 4 of the spoiler for sealing. This sponge strip is the third sealing strip 5.

[0118] Meanwhile, a U-shaped slot protrusion 19 is designed at the bottom of the mounting groove 16 to cooperate with the inner panel 6 of the decorative panel to fix the bottom edge of the inner panel 6 of the spoiler decorative panel; and the outer panel 4 of the spoiler and its inner panel 3 are bonded together with structural adhesive to form the spoiler mounting plate assembly.

[0119] In addition, the inner panel 6 of the spoiler decorative panel is designed with positioning pins (referring to the above-mentioned inner panel positioning pins 24), pre-embedded bolts (referring to the above-mentioned fixing bolts) and connecting slots 27 to fix it to the outer panel 4 of the spoiler.

[0120] Meanwhile, a camera through hole, mounting hole, and positioning pin are designed at the top center of the inner panel 6 of the decorative panel to fix the top camera, and an adhesive surface is designed on its top to fix the outer panel 7 of the spoiler decorative panel; finally, a snap-fit ​​plate 29 is designed at the front end of the top of the outer panel 7 of the spoiler decorative panel, and the snap-fit ​​surface is designed with support columns that are evenly distributed; and an adhesive surface is designed on the top of the outer panel 7 of the spoiler decorative panel, which is bonded to the inner panel 6 of the spoiler decorative panel with structural adhesive 34 to form the spoiler decorative panel assembly.

[0121] Meanwhile, in this invention, the inner spoiler plate 3, the outer spoiler plate 4, and related structures constitute the spoiler mounting plate assembly.

[0122] During actual installation and connection, the spoiler trim piece engages with the outer plate slot 21 on the top of the spoiler outer plate 4 via its top snap-fit ​​plate 29, and then combines with the spoiler mounting plate assembly via screw connection to form the spoiler assembly 1-1.

[0123] Subsequently, the upper sealing strip 1 and the lower sealing strip 2 are glued to the top and bottom of the inner panel 3 of the spoiler to form a complete spoiler assembly 1-1, and finally installed on the rear sheet metal of the roof through W-shaped fixing points.

[0124] This type of spoiler structure ensures both an aesthetically pleasing appearance and meets sealing requirements.

[0125] This invention has the following innovative features and advantages:

[0126] Multiple parts are combined to form a whole, meeting waterproof and sealing requirements; multiple seals are used to effectively block water flow; the product has an internal water-guiding structure to ensure smooth drainage of internal water; the W-shaped fixing structure with alternating screws and snaps facilitates installation; the support ribs have a guiding function, which is conducive to assembly.

[0127] Specific examples:

[0128] like Figure 1 As shown, a waterproof spoiler assembly 1-1 is formed by combining four main components into a whole, and achieves waterproof sealing of the spoiler through two sealing structures. This structure mainly includes an inner spoiler plate 3, an outer spoiler plate 4, an inner spoiler decorative plate 6, and an outer spoiler decorative plate 7.

[0129] The first sealing structure features a sponge strip (8mm wide and 3mm thick) between the top of the spoiler and the roof, constructed with an interference fit. This prevents most of the water at the rear of the roof from passing over the spoiler and entering the cavity formed by the spoiler and the rear of the roof, and directs the rainwater to the sides of the roof, where it flows to the ground through the side drainage channels.

[0130] The secondary seal also uses a sponge strip (8mm wide, 3mm thick), which uses an interference fit to seal the gap between the bottom of the spoiler and the rear of the top cover. As a supplement to the primary seal, it prevents rainwater from flowing to the bottom of the spoiler and accumulating in the rear door seal strip if the primary seal fails, thus preventing the seal strip from failing.

[0131] like Figure 2 As shown, the top and bottom of the inner plate 3 of the spoiler are designed with a sponge strip bonding surface at the joint with the rear of the top cover to facilitate sponge strip bonding.

[0132] The top sponge bonding surface is mainly large with a width of 10-15mm. The bonding surface near the fixing clip 11 is designed with dense reinforcing ribs instead of large bonding surfaces to enhance the strength of the fixing clip 11.

[0133] The upper and lower ends of the area where the spoiler outer panel 4 is attached are designed with a sealant bonding surface with a width greater than 10mm and a minimum width of 8mm in some local areas. The gap between the two is controlled at about 0.5mm. The bonding is done with room temperature structural adhesive with a width of 10mm and a thickness of 0.5mm. The middle area of ​​the spoiler inner panel 3 is designed with mounting points, which are arranged in a cross pattern of bolts and fixing clips 11 in a W-shape to facilitate assembly and installation.

[0134] Meanwhile, a drainage hole 13 is designed at the lowest point of the bottom of the outer plate 4 of the spoiler to prevent water from accumulating between the inner and outer plates of the spoiler.

[0135] like Figure 3 , 6As shown, the top and bottom of the outer panel 4 of the spoiler and its inner panel are also designed with adhesive surfaces. The middle part is designed with a spoiler decorative panel installation structure, and a top camera wiring harness through hole is designed in the center. Due to the shape, the water-blocking ribs 18 around the through hole are lower in the front and higher in the back (0-5mm), which cannot effectively prevent water from seeping into the through hole through the gap between the outer panel 4 of the spoiler and the top of the spoiler decorative panel. Therefore, a sponge strip is designed around the water-blocking ribs 18. The sponge strip is equivalent to the first sealing strip. Its width is 3mm and its height is 5mm. The combination of the two is used to guide the water flow and prevent the water from directly entering the hole.

[0136] A sponge strip is designed for sealing at the upper part of the clearance hole 4-1 and at the joint between the inner panel of the decorative part and the outer panel 4 of the spoiler. This sponge strip is the third sealing strip 5; its size is 3*3mm and its compression is greater than or equal to 70%. A slot boss 19 is designed at the bottom of the mounting groove 16 where it mates with the inner panel 6 of the spoiler decorative part to fix the bottom edge of the inner panel 6 of the spoiler decorative part. From this point on, the outer panel 4 of the spoiler and its inner panel are bonded together with room temperature structural adhesive to form the secondary assembly of the spoiler.

[0137] like Figure 4 As shown, the inner panel 6 of the spoiler decorative panel is equipped with 3 positioning pins and 4 pre-embedded bolts. The bottom is designed with 8 U-shaped slots to fix it to the outer panel 4 of the spoiler. The top of the inner panel 6 is designed with 1 camera through hole, 2 camera mounting holes and positioning pins to fix the top camera. Finally, the top of the inner panel 6 of the spoiler decorative panel is designed with an adhesive surface with a width greater than 10mm and a local width of not less than 8mm. The gap between the inner panel 6 and the outer panel 7 of the spoiler decorative panel is controlled at about 0.5mm. It is bonded with room temperature structural adhesive with a width of 10mm and a thickness of 0.5mm.

[0138] like Figure 5 , 6 As shown, the outer panel 7 of the spoiler decorative panel is designed with a snap-fit ​​plate 29 at the top front end, and a support column is designed above the snap-fit ​​plate 29, which is evenly distributed. This support column also has a guiding function, which makes it easy for the outer panel 7 of the spoiler decorative panel to be installed in the outer panel slot 21 on the outer panel of the spoiler outer panel 4. The outer panel 7 of the spoiler decorative panel is designed with an adhesive surface at the top rear end, which is bonded to the inner panel 6 of the spoiler decorative panel with room temperature structural adhesive to form the spoiler decorative panel assembly.

[0139] Finally, the spoiler trim assembly is inserted into the connecting slot 27 on the top of the spoiler secondary assembly via the snap-fit ​​plate 29 on its top, and is fixed to the spoiler secondary assembly by the bolt in the middle, forming the spoiler assembly 1-1.

[0140] like Figure 7 As shown, the upper sealing strip 1 and the lower sealing strip 2 are then glued to the top and bottom of the inner panel 3 of the spoiler to form a complete spoiler assembly 1-1, and finally installed on the rear sheet metal of the roof through W-shaped fixing points.

[0141] Body sheet metal 1-2 includes first sheet metal 35, second sheet metal 36 and third sheet metal 37.

[0142] This type of spoiler structure ensures both an aesthetically pleasing appearance and meets sealing requirements.

[0143] Obviously, the specific implementation of this invention is not limited to the above-described methods. Any non-substantial improvements made using the inventive concept and technical solution of this invention are within the protection scope of this invention.
