Interpupillary distance adjustment module and head mounted electronic device

Abstract

An interpupillary distance adjustment module includes: a first optical module base including a first slider and a first linkage point; a second optical module base including a second slider and a second linkage point; a linkage mechanism including a linkage rod, a third point and a fourth linkage point; and a base including a first groove, a second groove and a shaft, wherein the first and second grooves are parallel to each other and define a groove direction; wherein when a toggle switch rotates the linkage rod, moves the first optical module base, or moves the second optical module base, the third and fourth linkage points and the first and second linkage points are simultaneously linked and moved, and then the first and second optical module bases are controlled to be equidistantly close to or far away from each other in the groove direction.
