US 12,591,137 B2 · Electronic devices with biased guide rails

Abstract

A head-mounted device may be provided with displays. The displays and lenses through which images on the displays are viewed may be mounted in optical modules. Positioners may be used to move the optical modules towards and away from each other to adjust the head-mounted device to accommodate different user interpupillary distances. To support and guide the optical modules, the optical modules may be slidably mounted to guide rails. The guide rails may be biased against the optical modules using biasing systems. By using the biasing systems, misalignment between the optical modules can be reduced. If desired, guide rail sensors may be used to monitor the positions of the guide rails. In some configurations, the optical modules may be mounted to the guide rails using kinematic mounting.

Dependent claims

A head-mounted device, comprising:

a head-mounted support structure having left and right guide rails;
and
left and right optical modules mounted for sliding motion on the left and right guide rails, respectively, wherein:
the right optical module has a first biasing system that presses against the right guide rail in a first direction and has a second biasing system that presses against the right guide rail in a second direction;
and
the left optical module has a third biasing system that presses against the left guide rail in a third direction and has a fourth biasing system that presses against the left guide rail in a fourth direction.
