Steering headlamp

Abstract

The invention provides a steering headlamp, which comprises a fixing unit, a car lamp unit, a driving mechanism and an inductor for sensing the rotational angle of the car lamp unit. The car lamp unit comprises a lamp main body rotationally mounted on the fixing unit, and a first fulcrum and a driving shaft, which are extended from the lamp main body. The driving shaft is capable of driving the lamp main body to rotate by using the first fulcrum as a pivotal central axis under the action of drive. The driving mechanism comprises a limiting gear and a steering driving member capable of moving between two limiting surfaces of the limiting gear. The steering driving member drives the driving shaft to rotate with respect to the first fulcrum. By the double-shaft design of the car lamp unit, the lamp main body has extremely excellent rotation stability, and the limiting gear and the inductor have the functions of limiting and sensing the rotation angle of the lamp main body.

Description

technical field [0001] The invention relates to a headlight, in particular to a turning headlight which is installed on a vehicle and can be rotated to change the irradiation angle. Background technique [0002] like figure 1 As shown, the steering headlight 1 disclosed in the U.S. Patent Publication No. US6,543,924 includes: a bracket 11 fixedly connected to the vehicle body, a vehicle lamp rotatably arranged on the bracket 11 Body 12, a power connector 13 electrically connected to the rear end of the lamp body 12, a drive unit 14 arranged under the lamp body 12 and driving the lamp body 12 to rotate, and a drive unit 14 and the mounting plate 15 between the lamp body 12 . The bracket 11 includes an upper support arm 111 and a lower support arm 112 spaced up and down and protruding forward. The upper support arm 111 has an upper installation hole 113 , and the lower support arm 112 has a lower installation hole 114 . The lamp body 12 is located between the upper and lowe...

AI Technical Summary

Problems solved by technology

Although the above-mentioned structural design improves the lack of uniaxial support and rotation in the US6,543,924 patent case, other problems arise, mainly because the sliding seat 232 drives the driving rod 221 to move left and right to change the rotation angle of the inner frame 22. Once When the rotation angle is large, that is, when the sliding seat 232 moves to the left or right, although the driving rod 221 moves left and right, the driving rod 221 becomes obliquely extended, and the driving rod 221 stretches into the coupling groove 233 The length of the headlight 2 becomes shorter, so when the rotation angle is too large or when it is rotated to the limit, the driving rod 221 may break away from the coupling groove 233, causing the danger of the components getting off the hook. , which limits its usability
