Problems solved by technology

[0002]Projector lamps are generally used for interior decoration and lighting to improve the atmosphere inside the car. The principle is to project the light source to the lens assembly through the lamp body set on the circuit board. Then the corresponding light beam is projected by the lens assembly to achieve the effect of projecting the corresponding image. Generally, it needs to be fixed to ensure that the projected image is stable and will not shake. The fixing is relatively firm and convenient, but it also causes certain problems. First, the shock resistance of the housing The effect is not good, the amount of vibration is very easy to affect the lens assembly inside the housing, and the waterproof effect of the housing is not good

Abstract

The invention relates to a projection lamp. The projection lamp comprises a casing, wherein a circuit board and a lens assembly are arranged in the casing; the casing comprises a casing front cover and a casing rear cover, the casing front cover comprises a first end cover and an inner side wall integrally arranged with the first end cover, and the casing rear cover comprises a second end cover and an outer side wall integrally arranged with the second end cover; the end part, opposite to the first end cover, of the inner side wall is in a first shape, and a seal washer is arranged between the casing front cover and the casing rear cover and has the first shape; an elastomer is arranged on the inner side wall and deforms inwards to enable the inner side wall to enter the casing rear cover more easily when the casing front cover and the casing rear cover are matched; meanwhile, the seal washer abuts against the inner surface of the second end cover to form a first chamber for mounting the lens assembly and the circuit board.

Description

technical field [0001] The invention relates to the field of automobile atmosphere lamps, in particular to a projection lamp. Background technique [0002] Projector lamps are generally used for interior decoration and lighting to improve the interior atmosphere of the car. The principle is to project the light source to the lens assembly through the lamp body set on the circuit board, and then the corresponding light beam is projected by the lens assembly to achieve the effect of projecting the corresponding image. Generally, it needs to be fixed to ensure that the projected image is stable and will not shake. The fixing is more firm and convenient, but it also causes certain problems. First, the shock resistance of the housing is not good, and the vibration is very easy to affect the lens assembly inside the housing. Second, the waterproof effect of the shell is not good. Contents of the invention [0003] The object of the present invention is to provide a projection l...
