Vehicle lamp color-changing device with swingable arm

摘要

A vehicle lamp color-changing device includes a bracket, a swinging unit mounted to the bracket and swingable about an imaginary axis, and a rotary driving unit. The swinging unit includes a colored lens and an eccentric member disposed offset from the imaginary axis. The rotary driving unit has a rotary drive mounted to the bracket, a swingable arm connected with the rotary drive, and a pulling rod connected with the swingable arm and the eccentric member pivotally. In this way, the swingable arm is drivenable by the rotary drive to drive the pulling rod to move the eccentric member and thereby cause the swinging unit to swing in a way that the colored lens is swingable between an active position and an inactive position. As a result, the vehicle lamp color-changing device responds fast and is small-sized so as to be easily arranged in the vehicle lamp.
