Head-Mounted Device With Adjustment Mechanism

An adjustment assembly configured to move an optical module of a head-mounted device, comprising:

• a first adjustment stage configured to be movably coupled to a primary housing of the head-mounted device and configured to move the optical module laterally relative to the primary housing;
• a second adjustment stage movably coupled to the first adjustment stage and configured to move the optical module vertically relative to the first adjustment stage;
• and
• a third adjustment stage movably coupled to the second adjustment stage and to the optical module, the third adjustment stage configured to move the optical module longitudinally relative to the second adjustment stage.

A head-mounted device, comprising:

• a primary housing;
• an optical module;
• and
• an adjustment assembly configured to move the optical module relative to the primary housing, including:
• a first rail connected to the primary housing,
• a first carriage slidably coupled to the first rail and configured to slide along the first rail to move the optical module laterally relative to the primary housing;
• a second rail connected to the first carriage,
• a second carriage slidably coupled to the second rail and configured to slide along the second rail to move the optical module vertically relative to the first carriage,
• a third rail connected to the second carriage, and
• a third carriage coupled to the optical module, slidably coupled to the third rail, and configured to move the optical module longitudinally relative to the second carriage.

A head-mounted device, comprising:

• a primary housing;
• an optical module movably coupled to the primary housing;
• and
• an adjustment assembly configured to move the optical module relative to the primary housing, including:
• a gross adjustment stage configured to move the optical module laterally relative to the primary housing, and
• a fine adjustment stage configured to move the optical module laterally relative to the gross adjustment stage,
• wherein the fine adjustment stage is configured to be controlled independent of the gross adjustment stage.
