Description

Technical Field

[0001] The invention belongs to the technical field of automobile wading protection, and in particular relates to a ventilation and waterproof structure for automobile high-water-level wading and an assembly method. Background Art

[0002] With the continuous development of the automotive market, both traditional fuel vehicles and new energy vehicles are competing and promoting their innovative technologies and highlights. In particular, the waterproof and electric shock safety of new energy vehicles is of particular concern to automakers and users. Urban flooding during the annual rainy season directly tests a vehicle's water resistance. The rear ventilator, which regulates air pressure inside and outside the vehicle, also requires critical waterproofing. When the vehicle's air conditioning is on external circulation and the vehicle is jolting, the ventilator blades open, allowing water to flow into the cabin, causing electrical components to malfunction, leading to vehicle safety issues and customer complaints.

[0003] In the related art, the waterproofing of ventilation frames is mainly dealt with by water-blocking solutions, which are more used to solve the problem of water entering the vents when users are driving on wet roads or in low to medium water levels. Publication No.: CN112644587A discloses a water-blocking structure for ventilation frames, which is designed to add a water-blocking plate with a plastic shielding part at the lower part of the joint between the bumper and the ventilation frame. This water-blocking plate is assembled and fastened to the bumper to block the water flow. The ventilation frame is conventionally arranged at the rear of the car, close to the upper side of the wheel, at a height of about 500 mm from the ground. In the user scenario of 60 mm wet road surface or 300 mm flooded road surface, the technical solution of using a plastic water-blocking plate can effectively block the rainwater thrown out or splashed by the wheels; when the depth of the water on the road exceeds the arrangement height of the ventilation frame, the arrangement height of the ventilation frame cannot be adjusted any higher due to the influence of the vehicle shape. When the water depth exceeds the wheel height and reaches 600 mm or 700 mm, the water flows directly over the bottom of the ventilation frame and invades the cabin through the blades, causing water ingress problems. The layout height and waterproof technology of the ventilation frame directly determine the low wading depth of the vehicle, so it is urgently needed to be improved. Summary of the Invention

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0021] like Figure 1 As shown, the waterproof structure of the automobile high-water-level wading ventilation frame consists of a ventilation frame assembly 1, a waterproof cover assembly 2, a water guide pipe assembly 3, a side outer panel 4 and a rear floor connecting plate 5.

[0022] One side of the ventilation frame assembly 1 faces the external environment of the vehicle, building a direct connection channel with the outside of the vehicle to ensure effective circulation of air inside and outside the vehicle when the vehicle is driving normally.

[0023] Combine Figure 2 It can be seen that the waterproof cover assembly 2 adopts a detachable installation design and is installed on the surface of the ventilation frame assembly 1 facing the interior of the car. While playing the role of air diversion, the assembly can efficiently collect water that penetrates through the ventilation frame assembly 1. In addition, Figure 6 As shown, the waterproof cover assembly 2 is provided with a plurality of vents 213. These vents 213 guide airflow from the vehicle's interior to the ventilation frame assembly 1, maintaining air circulation within the vehicle and providing a preliminary barrier to water flow when the vehicle is wading. One end of the water conduit assembly 3 is detachably connected to the waterproof cover assembly 2. Its primary function is to establish a water discharge channel, directing water entering the waterproof cover assembly 2 to the exterior of the vehicle, protecting the interior from flooding and effectively improving vehicle safety during wading.

[0024] The side panels 4 serve as support components for mounting the ventilation frame assembly 1, ensuring the secure attachment of the entire waterproof structure to the vehicle. The rear floor connecting plate 5 is attached to the bottom of the side panels 4 and is located on the bottom of the vehicle, connecting to the end of the water conduit assembly 3 that is away from the waterproof cover assembly 2.

[0025] like Figure 3 As shown, the ventilation frame assembly 1 consists of a ventilation frame 11, a sealing rubber ring 12, and several blades 13. The ventilation frame 11 is a rectangular frame that is mounted on the surface of the side panel 4, with one side facing directly outside the vehicle, enabling communication with the external environment. In addition, the surface of the frame facing the outside of the vehicle is provided with several inclined surfaces arranged in an array, each of which is provided with ventilation holes, which provide a basic path for air circulation; specifically, Figure 3 Three stair-shaped inclined surfaces are provided in the middle, filling the inner surface of the ventilation frame 11. The sealing rubber ring 12 is arranged around the circumference of the ventilation frame 11 and is tightly connected to the side panel 4 through an interference fit. Specifically, the sealing rubber ring 12 is made of TPV material that is resistant to high temperatures, has low compression set, and is resistant to aging and corrosion. It is integrated into the ventilation frame 11 through an injection molding process.

[0026] Combine Figure 9 As can be seen, the three blades 13 are rotatably mounted on the inclined surface of the ventilation frame 11, completely covering the ventilation holes on each inclined surface. When the vehicle is in motion, airflow impacts the blades 13, prompting them to rotate flexibly. This not only regulates the ventilation volume but also provides a certain degree of airflow disturbance and reduces wind noise. Furthermore, a rotating shaft 113 is mounted on the inclined surface of the ventilation frame 11. This shaft 113 serves as a mounting support for the blades 13, providing stable support and a reliable rotation structure for their rotation.

[0027] It should be noted that the blades 13 can generally be made of EPDM (Ethylene-Propylene-Diene Monomer Rubber).

[0028] like Figure 5 As shown, the waterproof cover assembly 2 includes a waterproof cover body 21 and a sealing sponge 22. The waterproof cover body 21 is generally rectangular in shape, with claws 211 provided on both the upper and lower sections for detachable connection with the ventilation frame 11. In addition, multiple ribs 212 are evenly arranged inside the waterproof cover body 21 to increase the body rigidity. The sealing sponge 22 is sealed and installed at the lowest point after the waterproof cover body 21 is connected to the ventilation frame 11. Figure 11 In addition, combined with Figure 4 As can be seen, a holder 111 is provided on the surface where the ventilation frame 11 and the waterproof cover body 21 are detachably connected, and a slot 112 is provided on the surface of the holder 111. A claw 211 of the waterproof cover body 21 is provided on the surface corresponding to the holder 111. When the ventilation frame 11 and the waterproof cover 12 are detachably connected, the claw 211 is engaged with the slot 112.

[0029] Further, combined with Figure 10It can be seen that a cavity-like space is formed between one end of the socket 111 and the ventilation frame 11, which can be used to install the side outer panel 4. In addition, the interference fit between the sealing rubber ring 12 and the side outer panel 4 is 1.5-2.0 mm to ensure the waterproof seal between the ventilation frame assembly 1 and the side outer panel 4.

[0030] It should be noted that to prevent water from flowing into the vehicle through the lowest assembly gap between the waterproof cover body 21 and the ventilation frame 11, a 2mm thick sealing sponge 22 is placed at the bottom of the waterproof cover body 21. The sealing sponge 22 is adhered to the waterproof cover body 21 using 3M adhesive. The sealing sponge 22 is made of EPDM material and has an interference fit of 0.5-1.0mm with the bottom of the ventilation frame 11 to ensure a waterproof seal between the waterproof cover assembly 2 and the ventilation frame 11. Furthermore, vents 213 with an area of ​​10,000 mm² are designed on the top and sides of the waterproof cover body 21 to ensure ventilation of the ventilation frame.

[0031] like Figure 7 and Figure 13 As shown, the water pipe assembly 3 includes an adapter 31, a drain pipe 32 and a drain plug 33. Figure 5 A drain port with a diameter of 10 mm is provided at the bottom of the waterproof cover body 21, and a drain pipe column 214 is provided at the drain port. The drain pipe column 214 is inserted into the adapter 31 and has an interference fit with the adapter 31. Specifically, the connection between the water pipe assembly 3 and the waterproof cover assembly 2 is achieved through the interference fit and snap connection between the adapter 31 and the drain pipe column 214. The drain pipe column 214 has an inner diameter of 10 mm and an outer diameter of 13 mm. The bottom 12 mm area adopts a variable diameter design. The head has an outer diameter of 12 mm and a slope of 7° to facilitate the insertion of the adapter 31. A limit platform 215 is designed on the top surface of the drain pipe column 214. When the adapter 31 is inserted into this position and the limit platform 215 is assembled in place. The bottom of the adapter 31 is inserted into the drain pipe 32. To ensure a watertight seal between the adapter 31 and the drain pipe 32, the inner diameter of the drain pipe 32 is 11 mm, the outer diameter is 14 mm, and the insertion depth of the drain pipe 32 is 12 mm. The lower end of the drain pipe 32 (the end away from the adapter 31) is inserted into the drain plug 33 to a depth of 25 mm, using an interference fit of 0.2 mm. Finally, the drain plug 33 is inserted into the mounting hole of the rear floor connecting plate 5. The drain plug 33 and the sheet metal have a Z-axis interference fit of 0.4 mm.

[0032] It should be noted that the length of the drain pipe 32 is adjusted according to different wading depths and the arrangement height of the ventilation frame body 1. The deeper the wading depth, the longer the drain pipe 32 in the middle of the water pipe assembly 3.

[0033] Here are two assembly methods: The first method is overall assembly. First, water pipe assemblies 3 of different lengths are selected according to the vehicle's wading requirements (different water depths such as 600mm, 700mm, 800mm, etc.). Then, the ventilation frame assembly 1, waterproof cover assembly 2 and water pipe assembly 3 are integrated and assembled together to obtain a pre-integrated component. The pre-integrated component is then assembled to the side outer panel 4 and the rear floor connecting plate 5.

[0034] During overall assembly, first insert the water pipe assembly 3 into the mounting hole of the side panel metal, then insert the ventilation frame assembly 1 and the waterproof cover assembly 2 into the mounting hole of the side outer panel 4 in parallel, and connect them to the mounting surface of the side outer panel 4 through the sockets 111 of the upper and lower frames; finally, insert the drainage plug 33 at the lower end of the water pipe assembly 3 into the mounting hole of the rear floor connecting plate 5 from inside the vehicle to complete the assembly.

[0035] The second method is split assembly. First, the ventilation frame assembly 1 is connected to the mounting surface of the side outer panel 4 through the sockets 111 of the upper and lower frames; then, the water pipe assemblies 3 of different lengths are connected to the waterproof cover assembly 2 according to the car's wading requirements; then, the connected waterproof cover assembly 2 and water pipe assembly 3 are connected to the card slot 112 from inside the car through card connection; finally, the drainage plug 33 at the lower end of the water pipe assembly 3 is inserted into the mounting hole of the rear floor connecting plate 5 to complete the assembly.

[0036] like Figure 8 As shown, the main principle of the ventilation frame waterproof structure provided in this embodiment is water diversion and drainage. When the vehicle is driving on a high-water road, water waves a will surge toward the ventilation frame assembly 1 and penetrate into the waterproof cover body 21 through the blades 13, then flow into the drainage pipe column 214, and finally be discharged out of the vehicle through the water guide pipe assembly 3. At the same time, when the vehicle is in the external circulation state, the airflow b inside the vehicle can be blown toward the blades 13 through the vents 213 on the top and sides of the waterproof cover body 21, and the angle of the blades 13 is opened by the rotating shaft 113 on the ventilation frame 11, as shown in FIG. Figure 12 , which guides the indoor air out of the car, realizing the water and gas diversion function of the car ventilation frame.

[0037] like Figure 9 The figure shows the matching relationship between the ventilation frame 11, the blades 13, the waterproof cover body 21 and the rotating shaft 113. Specifically, the surface of the ventilation frame 11 facing the interior of the car is provided with a step structure, and the waterproof cover body 21 is also provided with a corresponding step structure, and the two are in contact with each other. In addition, on the inclined surface of the ventilation frame 11, the rotating shaft 113 can be designed to be an integral structure with the ventilation frame 11. The rotating shaft 113 extends from the inclined surface to the front of the ventilation frame 11, and a block is provided at the end. The middle is a shaft body that can be used to install the blades 13, so as to prevent the blades 13 from falling off the rotating shaft 113.

[0038] like Figure 10As shown, it shows a partial enlarged view of the upper end installation of the ventilation and waterproof structure for high-water wading of automobiles. Specifically, the cross-section of the ventilation frame 11 is two connected L-shaped, wherein the first L-shaped structure forms an annular groove surrounding the frame on the surface of the ventilation frame 11 facing the outside of the automobile. A sealing rubber ring 12 is provided at the vertical end of the second L-shaped structure, which is connected to the side outer panel 4. At the same time, a clamping seat 111 is installed on the annular surface on the back of the ventilation frame 11 (the horizontal section surface of the second L-shaped structure in the figure). The clamping seat 111 is clamped with the side outer panel 4. At the same time, the clamping groove 112 on the clamping seat 111 is clamped with the clamping claw 211 of the waterproof cover body 21. Extending inward from the clamping claw 211, the step structure of the waterproof cover body 21 is counteracted by the step structure of the ventilation frame 11.

[0039] like Figure 11 As shown, it shows a partial enlarged view of the lower end installation of the ventilation and waterproof structure for automobiles wading at high water levels. Specifically, the cross-section of the lower end of the ventilation frame 11 is composed of two special-shaped L-shaped structures, and the angle between the "horizontal section" and the vertical section is an obtuse angle, wherein the inner surface of the end of the second L-shaped structure is sealed to the waterproof cover body 21 through the sealing sponge 22. At the same time, the sealing rubber ring 12 at the vertical end of the second L-shaped structure cooperates with the side outer panel 4, and the side outer panel 4 is clamped in the clamping groove 112 of the clamping seat 111 (the same installation form as the upper end of the ventilation frame 11). In addition, when the blades 13 at the bottom layer are not blown up, their ends can be placed on the inner surface of the ventilation frame 11, and the inner surface of the ventilation frame 11 will be provided with a corresponding inclined surface to adapt to the ends of the blades 13.

[0040] like Figure 12 As shown, the upper portion of the inner surface of the adapter 31 is provided with a stepped surface, and the end of the drain pipe column 214 is provided with a barbed structure. When the drain pipe column 214 is inserted into the adapter 31, the barbed structure can be locked in the position of the stepped surface. In addition, the lower portion of the inner surface of the adapter 31 is also provided with a stepped surface, which is used to support the drain pipe 32 inserted into the adapter 31.

[0041] like Figure 13 As shown, the side outer panels 4 and the rear floor connecting plate 5 are both sheet metal structures, with the bottom of the side outer panels 4 welded to the side edges of the rear floor connecting plate 5. Furthermore, a mounting portion for the rear floor connecting plate 5 is provided in the middle of the drain plug 33. This mounting portion is a revolved body with an overall right-angled triangle cross-section (with smoothed edges and an arc-shaped hypotenuse). An annular mounting groove is provided on the surface of the mounting portion, into which the rear floor connecting plate 5 fits.
