Description

Technical Field

[0001] The utility model relates to the technical field of automobile lamp covers, and particularly relates to a durable sealed lamp cover for an automobile headlamp. Background Art

[0002] The lamp cover of an automobile headlamp is an indispensable part of the automobile lighting system, and it undertakes multiple functions and roles. The lamp cover is a protective shell covering the outside of the headlamp, and its main function is to protect the internal components such as bulbs and reflectors from the influence of the external environment, such as dust, moisture and physical damage.

[0003] Currently, when connecting the existing lamp cover and the lamp cover end cap, the sealing between the lamp cover and the lamp cover end cap is often carried out through a sealing ring. However, when the existing sealing ring is used to seal the lamp cover and the lamp cover end cap, the sealing effect is poor, which easily causes rainwater and the like to enter the interior of the lamp cover, resulting in damage to the headlamp inside the lamp cover.

[0004] Therefore, a durable sealed lamp cover for an automobile headlamp is proposed. Content of the Utility Model
