Abstract

The utility model relates to the technical field of vehicle horns, in particular to a vehicle air horn structure which comprises a base and a rotating shaft, the inner wall of the base is rotationally connected with the rotating shaft through a bearing, the upper end of the rotating shaft is fixedly connected with a shell, a dust cover moving mechanism is arranged in the shell, and the inner wall of the shell is fixedly connected with an air box. Through cooperation of the shell and the dust cover moving mechanism, the motor drives the cam to rotate, the cam drives the connecting plate to move on the shell, meanwhile, the connecting plate slides on the sliding rod, the spring enables the connecting plate to be always attached to the cam, the connecting plate drives the dust cover to move, and after the dust cover moves away from the surface of the horn opening, vibration sound of the reed is transmitted out of the horn opening. By means of the mode, the dust cover can be moved away when the horn is used, sound transmission is prevented from being blocked, and the using effect of the air horn structure is improved.
