[0038] like Figure 1 and Figure 4 As shown, in one embodiment, the housing 300 is a shark fin type. It can be understood that the shark fin type housing structure has at least the following functions: 1. The appearance is streamlined, which improves the appearance and grade of the vehicle; 2. Reduce air resistance. The special shape of the shark fin can cut and divert airflow, thereby reducing wind resistance and helping to save fuel; 3. Easy installation. The installation of the shark fin antenna is usually simple and convenient, and does not require special tools or modifications.

[0039] like Figure 3 As shown, in one embodiment, the automobile antenna structure 10 further includes a mounting post 600, which is disposed on the bottom surface of the base 200, and the mounting post 600 is disposed adjacent to the threading boss 220, and the second sealing ring 500 is disposed on the mounting post 600 and the threading boss 220. In this embodiment, the mounting post 600 is cylindrical, and is used to support and fix the antenna structure 10 when it is installed on the automobile roof.

It can be understood that by adding screws, the connection between the base 200 and the housing 300 is more secure.

[0042] like Figure 4 As shown, in one embodiment, a housing 300 is provided with a receiving cavity 301, and the base 200 is located in the receiving cavity 301 and connected to the housing 300. It can be understood that the space of the receiving cavity 301 inside the housing 300 is large enough to accommodate the base 200 and other antenna structures, so that when the antenna structure 10 is installed on the roof of a car, all components are accommodated in the housing 300 and protected by the housing 300.

[0043] like Figure 3 As shown, in one embodiment, the second sealing ring 500 is bonded to the bottom of the base 200. It can be understood that, by bonding, the second sealing ring 500, the base 200 and the car roof form a closed outer sealed space to prevent the wire 20 passing through the threading hole 220a from being invaded by external moisture.

[0044] like Figure 2 As shown, in one embodiment, the first sealing ring 400 is a rubber ring. It can be understood that the rubber ring is a deformable soft structure, which can be deformed when it abuts against the hard shell 300 to cover the connection, thereby forming a sealed space, isolating moisture from entering the sealed space in the shell, and achieving a waterproof effect. Of course, in other embodiments, the first sealing ring 400 can also be made of silicone or other polymer materials.

[0045] like Figure 3As shown, in one embodiment, the second sealing ring 500 is waterproof foam. It can be understood that the waterproof foam is a deformable soft structure. When the car antenna structure 10 is installed on the car roof, the waterproof foam is squeezed. After the waterproof foam reaches a certain amount of compression, it will form a structure similar to silicone rubber to isolate moisture from entering the sealed space outside the shell, achieving a waterproof effect.

[0046] The present application also provides a new energy vehicle, comprising the vehicle antenna structure 10 of any of the above embodiments.

[0047] Compared with the prior art, the present invention has at least the following advantages:

When the automobile antenna structure 10 is installed on the automobile roof, the base 200, the second sealing ring 500 and the automobile roof form a sealed space outside the shell, which improves the sealing performance of the connection between the base 200 and the automobile roof. By providing the first sealing ring 400 and the second sealing ring 500, the waterproof performance of the automobile antenna structure 10 is improved. Furthermore, a sealing portion 310 adapted to the shape of the first sealing ring 400 is provided inside the outer shell 300. The sealing portion 310 is located in the accommodating groove 210 and is in interference fit with the first sealing ring 400. That is, the outer shell 300, the base 200, the first sealing ring 400 and the sealing portion 310 are connected to form a more sealed sealed space inside the shell, thereby improving the sealing effect of the first sealing ring 400 and further improving the waterproof performance of the automobile antenna structure 10.
