Vehicle headlamp lens assembly capable of achieving regional illumination

Abstract

The invention discloses a vehicle headlamp lens assembly capable of achieving regional illumination and belongs to the field of optical lenses. The vehicle headlamp lens assembly comprises a lens, a bracket, a bottom plate, a reflection bowl and a mounting seat. The lens is fixedly arranged on the bracket, the reflection bowl is connected with the mounting seat, the bracket and the reflection bowl are correspondingly and fixedly arranged on the upper surface and the lower surface of the bottom plate, and the mounting seat is connected with a lens fixing component corresponding to the vehicle headlamp lens assembly. The bottom plate is at least provided with two regional light-changing mechanisms which are independent of each other during work. The regional light-changing mechanisms are mounted together side by side. Each regional light-changing mechanism comprises an electromagnet, a magnet core, a connecting plate, a support shaft and a light barrier. The electromagnets are fixed to the bottom plate. The light barriers are connected with the bottom plate through the corresponding support shafts. The light barriers are fixed to the corresponding magnet cores through the corresponding connecting plates. The magnet cores are connected with the corresponding electromagnets. By the adoption of the vehicle headlamp lens assembly capable of achieving regional illumination, high beam and low beam integration and regional illumination are achieved, so that the problem of the glare of a headlamp is avoided while the vision of a driver is guaranteed to the maximum extent.

Description

technical field [0001] The invention belongs to the field of optical lenses, in particular to a vehicle headlight lens assembly capable of realizing sub-area lighting. Background technique [0002] The problem of traffic safety has been paid more and more attention, because traffic accidents caused by the glare of car lights have become one of the main reasons for night driving safety accidents. But at present, the single-light lens and double-light lens used in the lights of most cars can only realize the switching of high and low beams, so it is easy for the driver not to turn off the high beam in the process of meeting cars in order to ensure his night driving vision. Dazzling lights problem. Therefore, the demand for sub-area lighting system was born. [0003] At present, there are single-vision lenses and double-vision lenses in the field of automotive headlight lens components. Single-vision lenses can only achieve one type of lighting (single high beam or low beam),...
