Description

Anti-interference structure of car lamp

Technical Field

The utility model relates to the technical field of automobile parts, in particular to an anti-interference structure of an automobile lamp.

Background

In order to improve the aesthetic appearance of a vehicle, a vehicle lamp is generally required to be as small as possible in a fit clearance with surrounding zero-locking members.

In order to ensure that the lamp and peripheral parts do not interfere on the premise of reducing the fit clearance. At present, the traditional anti-interference structure generally adopts two modes:

mode one: the interference between the lamp and peripheral parts is prevented by directly injecting the limiting ribs on the lamp shell. In this way, the firmness of the interference preventing structure can be ensured, but the structure is formed by hard plastic and is in hard contact with the peripheral parts, so that paint on the surfaces of the peripheral parts is easily scratched. Besides the influence on the appearance quality, the metal parts have the risk of being rusted after losing the protection of the surface paint, and the aesthetic property of the vehicle and the service life of the metal plates are seriously influenced.

Mode two: the soft gasket is stuck on the lamp shell, namely, the soft gasket with a certain thickness is stuck on the lamp shell, so that when the distance between the lamp and the peripheral part is smaller, a certain interval and buffering effect are achieved, and the lamp and the peripheral part are prevented from being in direct contact. Although the damage of hard plastic to peripheral parts in the first mode can be avoided, the adhesive is limited, and the adhesive is attenuated along with long-time exposure in the external environment, so that the gasket is easy to fall off when the lamp is assembled or disassembled, and the original anti-interference effect is lost.

Therefore, it is necessary to design a lamp interference preventing structure which is not easy to fall off and prevents the surrounding parts from being scratched.
