DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments of the present application.

[0025] It should be understood that, in the description of the present application, the terms "upper", "lower", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must be provided with a particular orientation, constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application. The terms "first" and "second" are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. That is, the features with "first" and "second" can explicitly or implicitly include one or more of the features. In addition, unless otherwise stated, the meaning of "multiple" is two or more.

[0026] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as there is no conflict between them.

[0027] As Figures 1-5 shown, the waterproof structure of the shark fin of the automobile according to the embodiments of the present application comprises a base 1, a shark fin shell 2 and a sealing gasket 3. Among them, the sealing gasket 3 is used to seal the gap between the base 1 and the shark fin shell 2, and to seal the gap between the base 1 and the vehicle roof 6.

[0028] The base 1 is configured to be installed on the vehicle roof 6. The shark fin shell 2 is installed on the upper surface of the base 1. The sealing gasket 3 is located between the base 1 and the shark fin shell 2, the lower surface of the sealing gasket 3 is covered on the base 1 and adheres to the vehicle roof 6, the lower surface of the sealing gasket 3 is protruded to form a first sealing ring 31, a second sealing ring 32 and a third sealing ring 33, the first sealing ring 31, the second sealing ring 32 and the third sealing ring 33 are distributed from outside to inside in turn, the lower surface of the sealing gasket 3 is recessed to form a first groove 34, a second groove 35 and a third groove 36, the first groove 34 is arranged around the outer periphery of the first sealing ring 31, the second groove 35 is arranged around the outer periphery of the second sealing ring 32, and the third groove 36 is arranged around the outer periphery of the third sealing ring 33.

[0029] Based on the above structure, when the base 1 and the shark fin shell 2 are installed, the sealing gasket 3 can be squeezed to seal the space between the base 1 and the shark fin shell 2, thereby achieving waterproof effect. When the base 1 is installed with the vehicle roof 6, the lower surface of the sealing gasket 3 is attached to the vehicle roof 6, and the first sealing ring 31, the second sealing ring 32 and the third sealing ring 33 effectively prevent water from entering after the sealing gasket 3 is squeezed. The first groove 34, the second groove 35 and the third groove 36 are formed by recessing, which can increase the height difference of the surface of the sealing gasket 3, further block the inflow or infiltration of water flow, and seal the space between the base 1 and the vehicle roof 6, thereby improving the reliability of waterproof.

[0030] As shown in Figure 1 , in some embodiments, a plurality of first bolts 4 are included, and the base 1 is connected with the shark fin shell 2 through the first bolts 4. In this way, the base 1 and the shark fin shell 2 can be easily disassembled and installed.

[0031] As shown in Figure 3 , in some embodiments, the sealing gasket 3 has a plurality of through holes 37, the through holes 37 are located between the first sealing ring 31 and the second sealing ring 32, and the first bolts 4 pass through the through holes 37 one by one. In this way, the base 1 and the shark fin shell 2 can be sealed by locking the first bolts 4.

[0032] As shown in Figure 1 , in some embodiments, a second bolt 5 is included, and the base 1 is installed on the vehicle roof 6 through the second bolt 5. In this way, the base 1 can be easily disassembled and installed on the vehicle roof 6.

[0033] In some embodiments, the sealing gasket 3 has a plum blossom hole 38, the plum blossom hole 38 is located in the third sealing ring 33, and the plum blossom hole 38 is provided on the second bolt 5. Specifically, the second bolt 5 passes through the plum blossom hole 38 upward and is locked by a nut.

[0034] In some embodiments, the height of the first sealing ring 31 is greater than the height of the second sealing ring 32 and the height of the third sealing ring 33. The deformation of the outer ring of the sealing gasket 3 is greater, and the first sealing ring 31 achieves the first layer of waterproof effect.

[0035] In some embodiments, the height of the second sealing ring 32 is equal to the height of the third sealing ring 33. The second sealing ring 32 and the third sealing ring 33 are used in cooperation to achieve the second layer of waterproof effect.

[0036] As shown in Figure 4 and 5As shown, in some embodiments, the depth of the first groove 34, the depth of the second groove 35 and the depth of the third groove 36 are all equal. The height difference of the surface of the sealing gasket 3 can be increased, further blocking the inflow or infiltration of water flow.

[0037] In some embodiments, the outer edge of the sealing gasket 3 is bent downward to form a folded edge 39. In installation, the folded edge 39 can be attached to the surface of the vehicle roof 6, thereby further improving the reliability of waterproofing.

[0038] The above description is only the preferred embodiments of the present application, and it should be pointed out that for ordinary skilled in the art, without departing from the technical principles of the present application, a number of improvements and substitutions can be made, and these improvements and substitutions should be considered as the protection scope of the present application.
