Description

Lens module with dimming mechanism, head lamp and vehicle

Technical Field

The utility model relates to the technical field of car lamps, in particular to a lens module with a dimming mechanism, a head lamp and a vehicle.

Background

Motorcycle headlamps are an important guarantee for safe driving of motorcycles, wherein the design and the manufacture of the headlamps are of great importance. Headlamps generally include lamp housings, heat sinks, reflectors, lens holders, lenses, trim pieces, position lights, trim rings, lamp covers, and the like. The combination of the position lamp and the headlamp makes the motorcycle headlamp have low cost and small occupied space. The function of the lamp housing is to protect the internal components while allowing light to pass through. In the field of optical design, refraction and reflection of light rays are key technical points, and through reasonable design, the light rays can be transmitted in an expected direction, so that a good lighting effect is achieved. The headlamp is usually realized in two ways, namely (1) headlamp beads and position lamp beads are respectively arranged on an inner PCB (printed Circuit Board), the lamp beads are diffused out through a lampshade, the cost is saved, but the brightness of the lamp is insufficient and the irradiation distance is insufficient, and (2) two PCBs are adopted, one PCB is used for realizing the lighting of the headlamp beads, the other PCB is used for realizing the lighting of the position lamp beads, the two PCBs are refracted by an outer lens or a thick wall, and light is diffused out through the lampshade.

As the regulations of motorcycle lamps are perfected, the second approach is becoming more and more the mainstream of design. The requirements for beam irradiation are that, in an empty vehicle state, the low beam of a headlight of an automobile or a motorcycle irradiates on a screen with a distance of 10m, the position in the vertical direction of the angle or the midpoint of the cut-off line of the low beam is not higher than a straight line with a height of less than or equal to 1000mm below the horizontal plane of the center of the low beam light transmitting surface and not lower than 300mm below the horizontal plane of the center of the low beam light transmitting surface, and that for a motor vehicle with a height of more than 1000mm below the horizontal plane of the center of the low beam light transmitting surface and not higher than a straight line with a height of 100mm below the horizontal plane of the center of the low beam light transmitting surface and not lower than 350mm below the horizontal plane of the center of the low beam light transmitting surface. In addition to motor tricycles and motorcycles equipped with a single headlight, the horizontal position of the headlight at the corner or midpoint of the cutoff line of the low beam should be shifted to the left by 170mm or less and to the right by 350mm or less than the treatment plane at the center of the light-transmitting plane of the low beam. In order to avoid too high or too low a low beam of the lamp after loading, it is therefore generally considered to add an adjusting mechanism to the headlight so that it has an adjusting range of up and down 3 ° to be able to be aligned with the irradiation position. However, miniaturization of the motorcycle head lamp presents a new challenge, and interference with the thick wall of the position lamp occurs when the head lamp lens module is dimmed up and down by using the dimming structure.
