Embodiment Construction

[0029] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0030] Such as figure 1 As shown, 1 is the fixed bracket, 2 is the adjusted component, and 3 is the adjustment mechanism.

[0031] The present invention relates to an adjusting device between optical units in a vehicle lamp and its fixing method, which includes an adjusted optical unit A1, a fulcrum screw 2, a support plate 3, a fixing bracket 4, a bushing 5, an elastic washer 6, and a stop washer 7 And fixing nut 8. The fulcrum screw 2 is provided with a hemispherical ball head 2a, and is fixedly connected with the internal thread provided on the optical unit 1 through a thread pair through the external thread 2b, so that the optical unit 1 can take the hemispherical ball head 2a of the fulcrum screw 2 as the center of rotation Perform universal rotation. The support plate 3 is provided with a ball socket with the same diameter and concentricity as the he...

Abstract

An adjusting device for optical units in a car lamp comprises a fixed bracket 4 and the optical units 1 arranged on the fixed bracket 4, and is characterized in that the optical units 1 are arranged on the fixed bracket 4 provided with a second ball socket 4a through a supporting point screw 2 and a supporting plate 3, wherein a hemispherical ball head 2a is formed in the middle of the supporting point screw 2, and a first ball socket 3a is formed in the middle of the supporting plate 3; the first ball socket 3a and the second ball socket 4a are concentric with the hemispherical ball head 2a; and the adjusting device for the optical units in the car lamp further comprises a bushing 5, an elastic washer 6, a retaining washer 7 and a fixing nut 8 which are arranged on the rear portion of the fixed bracket 4, penetrate through the supporting point screw 2 and are arranged in sequence.

Description

technical field [0001] The invention relates to an adjusting device between optical units in a vehicle lamp and a fixing method thereof. Background technique [0002] With the continuous maturity of LED light-emitting chip technology, its small size, long life, high luminous efficiency and other characteristics make LED light-emitting chips more and more used in the automotive lighting industry to replace traditional light bulbs. The above characteristics also make it possible for the composite multi-optical unit system to realize the lighting function of car lights. Due to the changeable shape and strong sense of technology, more and more car lights are designed to use multi-optical unit systems, but at the same time it also brings differences between optical units. Adjustment and fixation problems. [0003] The current common adjustment and fixing method is to design the adjustment mechanism to be connected and adjustable through a threaded pair, and use the self-locking ...
