US 12,601,963 B2 · External electric adjusting module and lens device

Abstract

An external electric adjusting module adapted for being externally connected to a lens includes a bracket including a first positioning portion, a gear set, a driving assembly driving the gear set to operate, and a variable resistance rotating member. The gear set is rotatably disposed on the bracket, is adapted for being externally connected to the lens, and includes a second positioning portion, a rotating shaft, and a first driving portion located on the rotating shaft. The variable resistance rotating member is sleeved on the rotating shaft, is electrically connected to the driving assembly, and includes a second driving portion corresponding to the first driving portion to be linked with the rotating shaft. When the gear set is located at an initial position together with the lens, the first and second positioning portions are aligned with each other, and the second driving portion abuts against the first driving portion.
