Headlight for vehicle with adjustable mirror

Abstract

A headlamp for automobiles with a movable reflector, comprising: a lamp body and a front lens for dividing a lamp chamber; a reflector housed in the lamp chamber and equipped with a light source; A dimming mechanism that can tiltably support the reflector. The dimming mechanism is composed of a dimming fulcrum, a dimming screw, and a nut member that is installed on the reflector and screwed with the dimming screw. The nut is guided by a sliding guide formed on the lamp body. The component is provided with a stress relief device with a spherical coupling structure at the mounting part of the nut component and the bracket. The ball part of the ball joint is formed on the body of the nut member on which the female thread part is formed, the slider supported by the slide guide is integrally formed on the side of the ball part, and the nut is supported by the ball housing part of the bearing attached to the bracket. The spherical part of the component. Therefore, it is possible to provide a movable reflector type automotive headlamp which reliably prevents reflector vibration, ensures smooth return of the dimming bolt, and has a simple reflector shape and mold structure for forming the reflector.

Description

technical field [0001] The present invention relates to a reflector movable type automotive headlight in which a reflector equipped with a light source is tiltably supported by a light adjusting mechanism relative to the lamp body, and in particular relates to a nut sliding guide formed on the lamp body that is connected with the light adjustment The mechanism member is a light adjusting fulcrum member screwed with a light adjusting screw, that is, a nut member, which is a movable reflector automotive headlamp. Background technique [0002] Conventional headlights for automobiles with movable reflectors such as Figure 30 As shown, on the front side of the synthetic resin lamp body 1, the synthetic resin reflector 2 integrated with the light source installation is composed of an inclined fulcrum, that is, a spherical coupling, and is screwed with two dimming screws respectively, and can move forward and backward in the axial direction. The moving fulcrum is supported by the ...
