摘要（英）：

The invention relates to an automobile headlamp structure, in particular to a sealing structure of an automobile headlamp shell. The sealing structure comprises a shell main body, a transparent cover plate tightly connected with the front end of the shell main body, and a back cover plate tightly connected with the back end of the shell main body, wherein an air hole for conducting an inner cavity of the shell main body with an external atmospheric space is formed in the shell main body; a switch is arranged on the air hole; when an automobile headlamp works, the switch is opened, so that the air hole is in a ventilation state; and the switch is a direct-current electric ball valve. The sealing structure of the automobile headlamp shell has the benefits of convenience for use, high reliability, good ventilation effect of the air hole and energy conservation.
