Problems solved by technology

In addition, when the bolt 7 loosens over time, the grooved ball bearing body 21A will be displaced relative to the reflector 3, and this displacement will cause a relative positional dislocation between the grooved ball bearing body 21A and the transmission push rod 32 , resulting in a decrease in the accuracy of the tilting action of the mirror 3

Embodiment Construction

[0017] Hereinafter, embodiments of the present invention will be described with reference to the drawings. figure 1 It is a front view of the first embodiment in which the reflector tilting device of the present invention is applied to the headlight of an automobile, figure 2 Is along figure 1 Cross-sectional view of the A-A line, and image 3 Is along figure 2 The enlarged top view seen in the direction of the B-B line. At the front opening of the lamp body 1 of the headlamp HL, the lamp glass 2 is sealed along its periphery, so that the lamp body 1 and the lamp glass 2 constitute a lamp room. A reflector 3 made of resin is installed in the lamp chamber. The inner surface of the reflector 3 is a rotating parabolic reflecting surface, and a light bulb installation hole is opened in the center to support the light bulb as a light source. The light socket 6 of 5 is detachably installed. A mirror tilting device 8 for adjusting the optical axis by tilting the above-mentioned mirro...

Abstract

Lamp for vehicle. A reflector slanting device which can slant the reflector in a light body is provided with a groove shape ball bearing body for converting the straight line motion of an actuator rod moved to the optical axis direction of the reflector in the lighting tool body to the slanting motion of the reflector. The groove shape ball bearing body is provided with a first fix part fixed the reflector and a second fix part inserted against the reflector. The fix work is simplified and position shift can be prevented by inserting the tip of a cross boss part provided on the reflector in the cross shape clearance formed by insertion walls and inserting the insertion pin of the cross boss part in the pin hole of the ball bearing body.

Description

Technical field [0001] The present invention relates to a vehicle lamp with a reflector tilting device, in particular to a structure of a reflector tilting device. The reflector tilting device is provided with a reflector for holding a light source in the lamp body. By tilting the reflector, It is possible to adjust the angle of the optical axis of the lamp. Background technique [0002] In the prior art, some of the headlamps used in automobiles and other vehicles are equipped with the reflector installed in the lamp body by tilting up and down, left and right to adjust the optical axis of the headlamp. The so-called headlight adjustment mechanism for optical axis adjustment; some are equipped with an automatic correction leveling optical axis adjustment mechanism that keeps the optical axis of the headlight at a certain angle corresponding to the tilting of the car body. No matter which design is adopted, in order to adjust the angle of the optical axis, a reflector tilting dev...
