[0024] As one embodiment of this utility model, such as Figures 1-3As shown, the present invention provides a leak-proof car roof vent assembly, comprising a split panel 1 and a car roof body 15. The split panel 1 is fixedly snapped onto the car roof body 15. Each of the four corners of the top of the split panel 1 has an embedding groove 8 for installing a limiting block 9. The tops of the four sets of limiting blocks 9 are fastened together with a first sealing plate 2. The first sealing plate 2 is a horizontally arranged rectangular frame structure. A water collection groove 3 is provided inside the first sealing plate 2. Water guide pipes 6 are fixedly inserted into both sides of one end of the first sealing plate 2. One end of the water guide pipe 6 is connected to the water collection groove 3. An arc groove 10 is provided at the bottom of the first sealing plate 2. A first sealing gasket 17 is fixedly glued to the bottom of the first sealing plate 2. The side of the first sealing gasket 17 away from the first sealing plate 2 is attached to the top of the split panel 1.

[0025] The outer edge of the upper end face of the first sealing plate 2 is provided with a groove 12 for installing the second sealing plate 4. The second sealing plate 4 is a horizontally arranged rectangular frame structure. The second sealing plate 4 is sleeved on the outside of the first sealing plate 2. The upper part of the inner wall of the second sealing plate 4 is provided with a fastener 5 that matches the groove 12. The bottom end of the second sealing plate 4 is fixedly glued with a second sealing gasket 18. The lower end face of the second sealing gasket 18 is in contact with the top end of the car roof body 15.

[0026] When in use, if the vehicle encounters rain or snow or passes through a flooded section of road, and rainwater drips onto the second sealing plate 4, most of the rainwater is blocked outside the component because the second sealing gasket 18 at the bottom of the second sealing plate 4 is in close contact with the top of the car roof body 15. If a small amount of rainwater still seeps in, it will flow into the water collection tank 3 along the slope of the top of the first sealing plate 2, and then be guided to the outside of the vehicle through the water guide pipe 6, thus preventing rainwater from seeping into the car.

[0027] This utility model also includes four sets of limiting blocks 9 arranged in parallel relative to each other, with the bottom end of the limiting blocks 9 fixedly inserted into the embedding groove 8.

[0028] The present invention also includes a limiting groove 11 adapted to the lower end face of the first sealing plate 2 located at the limiting block 9, and the first sealing plate 2 is fixedly connected to the top of the limiting block 9 by a first self-tapping screw.

[0029] The present invention also includes that the second sealing plate 4 is provided with through holes 7 on both sides near the end of the water guide pipe 6 for one end of the water guide pipe 6 to pass through.

[0031] The present invention also includes a waterproof pad 16 glued to the lower end face of the fastener 5 and the bottom end of the protrusion 14, the bottom end of the protrusion 14 being inserted into the groove 13, and the bottom end of the waterproof pad 16 being located in the groove 13.

[0032] In use, the split panel 1 is first fixedly snapped onto the car roof body 15; then the first sealing plate 2 is fastened to the top of the four sets of limiting blocks 9. Since the lower end face of the first sealing plate 2 is provided with a matching limiting groove 11 at the limiting block 9, the first self-tapping screw is used to pass through the limiting groove 11 and fix it to the top of the limiting block 9, so that the first sealing plate 2 is securely installed; then the second sealing plate 4 is placed on the outside of the first sealing plate 2. Using the fastener 5 that matches the fastening groove 12 on the upper part of the inner wall of the second sealing plate 4, the protrusion 14 on the lower end face of the fastener 5 is inserted into the groove 13 on the bottom inner wall of the fastening groove 12. At the same time, the bottom end of the protrusion 14 and the waterproof pad 16 on the lower end face of the fastener 5 also enter the groove 13, so as to achieve a tight installation of the second sealing plate 4; the second sealing plate 4 is provided with through holes 7 on both sides near the end of the water guide pipe 6. One end of the water guide pipe 6 passes through the through holes 7 to ensure that the water guiding function is not affected.

[0033] When the vehicle encounters rain or snow or passes through flooded sections of road, and rainwater drips onto the second sealing plate 4, most of the rainwater is blocked outside the component because the second sealing gasket 18 at the bottom of the second sealing plate 4 is in close contact with the top of the car roof body 15. If a small amount of rainwater still seeps in, it will flow into the water collection tank 3 along the slope of the top of the first sealing plate 2, and then be guided to the outside of the vehicle through the water guide pipe 6, thus preventing rainwater from seeping into the car.
