Light pattern conversion limiting mechanism of light pattern conversion drive device and light pattern conversion noise reduction method of light pattern conversion drive device

Abstract

The invention discloses a light pattern conversion limiting mechanism of a light pattern conversion drive device and a light pattern conversion noise reduction method of the light pattern conversion drive device. The light pattern conversion limiting mechanism is arranged on a light pattern conversion drive device shell of a car lamp light pattern conversion device; a movable visor is arranged on a fixed visor of the car lamp light pattern conversion device and is rotationally connected with the fixed visor through a rotary shaft and a swing rod of the light pattern conversion drive device; the limiting mechanism comprises a passing light elastic rotary shaft limiting pad and a distance light elastic rotary shaft limiting pad; the passing light elastic rotary shaft limiting pad is arranged on the upper portion of the movable visor and used for preventing impact between the movable visor and the fixed visor when the movable visor rotates to the passing light position; and the distance light elastic rotary shaft limiting pad is arranged on a side cover sub assembly at one end of the front portion of the light pattern conversion drive device shell and used for preventing impact between the movable visor and the light pattern conversion drive device shell when the movable visor rotates to the distance light position. The light pattern conversion limiting mechanism is used for limiting the movable visor during light pattern conversion, reduces collision noise of the movable visor during electromagnet attraction and releasing, avoids light pattern shaking and ensures reliability of light pattern conversion.

Description

technical field [0001] The present invention relates to a rotary electromagnetic actuator for vehicle lights. Specifically, the present invention relates to a light pattern change limiting mechanism and a noise reduction method for a light pattern conversion driving device of a car light pattern transformation device. The light type conversion limiting mechanism and noise reduction method of the type conversion driving device are used for the light type conversion driving device of the vehicle light type conversion device to limit the movable sunshade when the light type is changed, and at the same time eliminate the movable sunshade. The collision noise generated when the electromagnet is engaged and released avoids light-shape shaking and ensures the reliability of light-shape transformation. Background technique [0002] When the driver is driving, it is inevitable that there will be car meeting and uphill and downhill situations. Especially when the car is driving at ni...

Problems solved by technology

In addition, the electromagnet will generate strong vibration when it is attracted and released, and it is easy to cause the light shape to shake, and this vibration will also cause failures such as loose connections, which will affect the reliability of the light shape conversion mechanism.
