[0002] In recent years, many cities in my country have been hit by heavy rains. After a heavy rain, the city was flooded and many cars were forced to wade through the water.
[0003] Currently, vehicles often use multiple seals to improve sealing to prevent water ingress. However, as seals age and their sealing performance deteriorates, water easily enters the vehicle cavity. Once water enters, it cannot be effectively drained away, causing water accumulation. This fails to effectively meet waterproofing and drainage requirements, leading to customer complaints. Utility Model Content
[0004] The purpose of the present invention is to overcome the above-mentioned shortcomings and provide a water-blocking and water-draining sealing structure for a water-wading vehicle. By setting a one-way drainage channel between the sealing strips, it can effectively block and drain water and is not afraid of wading.

DETAILED DESCRIPTION Example 1
[0031] See also Figure 1-5 The utility model relates to a water-blocking and water-draining sealing structure for a water-crossing vehicle. Three sealing strips 1, a first sealing strip 2, and a second sealing strip 3 are sequentially arranged between the door sheet metal 7 and the side panel metal 8 from the outside to the inside. Drain holes 4 are arranged on the outside of the three sealing strips 1 and the first sealing strip 2 below the water-cut waistline, and exhaust holes 5 are arranged on the inside. The drainage holes 4 and exhaust holes 5 are arranged on the corresponding sealing strip bubble tubes. The exhaust holes 5 are used to discharge the gas in the sealing strip bubble tube when closing the door, which is beneficial to the deformation of the sealing strip bubble tube and the reduction of the closing force. At the same time, the exhaust holes 5 also serve as a water inlet for water to flow out of the vehicle when draining. The drainage holes 4 are connected to a one-way drainage valve 6. The drainage holes 4 and the exhaust holes 5 are connected between each sealing strip to form a one-way drainage channel, and water is discharged outward along the one-way drainage channel. The one-way drainage valve is in a closed state when there is no water or when there is water outside the vehicle. It opens only when the water pressure inside the vehicle is greater than the water pressure outside the vehicle, and serves as a water outlet.
[0032] The plurality of drainage holes 4 are evenly spaced along the length direction of the three sealing strips 1 or the first sealing strip 2 , and each drainage hole 4 is correspondingly connected to a one-way drainage valve 6 .
[0033] The second sealing strip 3 located on the innermost side is also provided with an exhaust hole 5 corresponding to the one-way drainage channel.
[0034] The one-way drain valve 6 blocks water from the outside to the inside and drains water from the inside to the outside.
[0035] Water easily accumulates at the corners of the three outermost sealing strips 1 , and drainage holes 4 are arranged at the corners of the three sealing strips 1 , and the drainage holes are used to install a one-way drainage valve 6 .
[0036] The one-way drain valve 6 includes an outer water stop plate 6.1 and an inner connecting ring 6.2. The inner side of the connecting ring 6.2 is connected to the water stop plate 6.1 through a rib 6.3. The water stop plate 6.1 passes outward from the inner hole of the connecting ring 6.2. Under the pull of the rib 6.3, the water stop plate 6.1 is pressed against the outside of the connecting ring 6.2, forming a closed state.
[0037] The outer diameter of the water stop plate 6.1 is larger than the inner diameter of the connecting ring 6.2, and smaller than the outer diameter of the connecting ring 6.2.
[0038] like Figure 2-5 The one-way drain valve 6 is pasted on the corresponding sealing strip.
[0039] When there is no water or when there is water outside the vehicle, the water stop piece 6.1 of the one-way drain valve 6 is pressed against the outside of the connecting ring 6.2, and the one-way drain valve 6 is in a closed state. As the water level rises, the closure becomes tighter, effectively preventing water from entering, thereby playing a sealing role; when water accumulates in the cavity between the door sheet metal and the side panel sheet metal, the water enters the sealing bubble tube of the corresponding sealing strip from the exhaust hole. When the water pressure outside the vehicle is lower than the water pressure inside the vehicle, the water stop piece 6.1 of the one-way drain valve 6 is lifted by the water, and the water is discharged outside the vehicle. Example 2
[0040] See also Figure 6-8 The utility model relates to a water-blocking and water-draining sealing structure for a water-wading vehicle. Three sealing strips 1, a first sealing strip 2, and a second sealing strip 3 are sequentially arranged between the door sheet metal 7 and the side panel metal 8 from the outside to the inside. Drain holes 4 are arranged on the outer sides of the three sealing strips 1 and the first sealing strip 2 below the water-cut waistline, and exhaust holes 5 are arranged on the inner sides. The drainage holes 4 and exhaust holes 5 are arranged on the corresponding sealing strip bubble tubes. The exhaust holes 5 are used to discharge the gas in the sealing strip bubble tube when closing the door, which is beneficial to the deformation of the sealing strip bubble tube and reduces the closing force. At the same time, the exhaust holes 5 also serve as a water inlet for water to flow out of the vehicle when draining.
[0041] The drain holes 4 are connected to a one-way drain valve 6. The sealing strips are connected through the drain holes 4 and the exhaust holes 5 to form a one-way drainage channel, through which water is discharged. The one-way drain valve is closed when there is no water or when there is water outside the vehicle. It opens to serve as a water outlet only when the water pressure inside the vehicle is greater than the water pressure outside.
[0042] The plurality of drainage holes 4 are evenly spaced along the length direction of the three sealing strips 1 or the first sealing strip 2 , and each drainage hole 4 is correspondingly connected to a one-way drainage valve 6 .
[0043] The second sealing strip 3 located on the innermost side is also provided with an exhaust hole 5 corresponding to the one-way drainage channel.
[0044] The one-way drain valve 6 blocks water from the outside to the inside and drains water from the inside to the outside.
[0045] Water easily accumulates at the corners of the three outermost sealing strips 1 , and drainage holes 4 are arranged at the corners of the three sealing strips 1 , and the drainage holes are used to install a one-way drainage valve 6 .
[0046] like Figure 7 The one-way drain valve 6 is in the shape of a flat trumpet, and the trumpet mouth gradually converges outward.
[0047] like Figure 7 , the one-way drain valve 6 is pasted on the three sealing strips 1; Figure 8 The one-way drain valve 6 is integrally injection-molded on the three sealing strips 1 .
[0048] When there is no water or when there is water outside the vehicle, the bell mouth of the one-way drain valve 6 is in a closed state. As the water level rises, the closure becomes tighter, effectively preventing water from entering, thereby playing a sealing role; when water accumulates in the cavity between the door sheet metal and the side panel sheet metal, the water enters the sealing bubble tube of the corresponding sealing strip from the exhaust hole. When the water pressure outside the vehicle is lower than the water pressure inside the vehicle, the bell mouth of the one-way drain valve 6 is opened under pressure to drain the water out of the vehicle. Example 3
[0049] See also Figure 9-12 The utility model relates to a water-blocking and water-draining sealing structure for a water-wading vehicle. Three sealing strips 1, a first sealing strip 2, and a second sealing strip 3 are sequentially arranged between the door sheet metal 7 and the side panel metal 8 from the outside to the inside. Drain holes 4 are arranged on the outer sides of the three sealing strips 1 and the first sealing strip 2 below the water-cut waistline, and exhaust holes 5 are arranged on the inner sides. The drainage holes 4 and exhaust holes 5 are arranged on the corresponding sealing strip bubble tubes. The exhaust holes 5 are used to discharge the gas in the sealing strip bubble tube when closing the door, which is beneficial to the deformation of the sealing strip bubble tube and reduces the closing force. At the same time, the exhaust holes 5 also serve as a water inlet for water to flow out of the vehicle when draining.
[0050] The drain holes 4 are connected to a one-way drain valve 6. The sealing strips are connected through the drain holes 4 and the exhaust holes 5 to form a one-way drainage channel, through which water is discharged. The one-way drain valve is closed when there is no water or when there is water outside the vehicle. It opens to serve as a water outlet only when the water pressure inside the vehicle is greater than the water pressure outside.
[0051] The plurality of drainage holes 4 are evenly spaced along the length direction of the three sealing strips 1 or the first sealing strip 2 , and each drainage hole 4 is correspondingly connected to a one-way drainage valve 6 .
[0052] The second sealing strip 3 located on the innermost side is also provided with an exhaust hole 5 corresponding to the one-way drainage channel.
[0053] The one-way drain valve 6 blocks water from the outside to the inside and drains water from the inside to the outside.
[0054] Water easily accumulates at the corners of the three outermost sealing strips 1 , and drainage holes 4 are arranged at the corners of the three sealing strips 1 , and the drainage holes are used to install a one-way drainage valve 6 .
[0055] like Figure 10 The one-way drain valve 6 is in the shape of a split cone cap, and has a plurality of cuts evenly distributed around the circumference of the one-way drain valve, which divides the one-way drain valve into a plurality of petals.
[0056] like Figure 10 The one-way drain valve 6 is integrally injection-molded on the first sealing strip 2; Figure 11 The one-way drain valve 6 is pasted on the first sealing strip 2.
[0057] When there is no water or when there is water outside the vehicle, the multiple petals of the one-way drain valve 6 are closed. As the water level rises, the closure becomes tighter, effectively preventing water from entering, thereby playing a sealing role; when water accumulates in the cavity between the door sheet metal and the side panel metal, the water enters the sealing bubble tube of the corresponding sealing strip from the exhaust hole. When the water pressure outside the vehicle is lower than the water pressure inside the vehicle, the petals of the one-way drain valve 6 are pressed open to drain the water outside the vehicle.
