External antenna structure of vehicle machine

The utility model discloses an external antenna structure of a vehicle machine. The external antenna structure comprises a shell, a base, an antenna assembly and a bottom cover, the bottom face of the shell is open, the base is embedded into the bottom face of the shell and detachably connected with the shell, the antenna assembly is arranged on the top face of the base, a wire of the antenna assembly penetrates out of the base, one side of the top of the shell is in slope transition, the bottom cover is arranged at the bottom of the shell and detachably connected with the base, the bottom cover and the base are arranged in a spaced mode, and a damping piece is further arranged between the bottom cover and the base. By adopting the above design, through the streamline-shaped arrangement of the shell, the wind resistance generated when the shell makes contact with air when an external vehicle moves at a high speed is reduced, meanwhile, the damping part is installed at the bottom of the base, and through the a
