AI Technical Summary

Technical Problem

In commercial vehicles, the dimming screw is prone to over-adjustment under extreme conditions, which can cause it to fall off, resulting in abnormal noises from the headlights and quality problems.

Method used

Design a limiting structure for a front combination lamp dimming assembly, including a dimming screw, a bracket, and a dimming ball head. The dimming ball head is fixed by the cooperation between the bracket and the dimming ball head, and the design of the spring sheet and connecting plate is used to prevent it from falling off, while allowing for adjustment and rotation.

Benefits of technology

It effectively prevents the dimming screw from falling off, improving the reliability and stability of the headlights and facilitating the adjustment of the beam angle.

Abstract

The utility model discloses a limiting structure of a front combination lamp dimming assembly, which comprises a dimming screw rod (1), a support and a dimming ball head (2), the dimming ball head (2) is arranged at the end part of the dimming screw rod (1), and the dimming ball head (2) is clamped in the support; the dimming screw rod (1) is firstly connected with the dimming ball head (2) through threads, then the dimming ball head (2) is fixed through the support, meanwhile, due to the fact that the dimming ball head (2) is spherical, after the dimming ball head (2) is clamped into the support, the dimming ball head (2) is connected with the support in a clamped mode, and therefore the dimming ball head (2) can have a certain rotation freedom degree, and the dimming ball head (2) can be conveniently adjusted. The dimming screw rod (1) connected with the dimming ball head (2) can rotate by a certain angle relative to the bracket, so that the effect of subsequently adjusting the angle can be achieved, and meanwhile, the effects of limiting the dimming screw rod (1) and preventing the dimming screw rod (1) from falling off are achieved by utilizing the matching of the bracket and the dimming ball head (2).
