Wearable electronic device for adjusting distance between lenses
A wearable electronic device includes an adjustment structure configured to adjust a distance between a first lens and a second lens. A user may wear the wearable electronic device and adjust an inter-lense distance so that there is a good match with the positions of their own eyes. The adjustment structure may include a lever, a first adjustment gear configured to be engaged with a first gear in a first position of the lever, a second adjustment gear configured to be engaged with the first gear and a second gear in a second position of the lever, and a third adjustment gear configured to be engaged with the second gear in a third position of the lever. The user may move the lever in or out to engage a different gear and then rotate the lever to adjust the inter-lense distance.
1 . A wearable electronic device comprising:
a first base configured to move in a first direction or a second direction opposite to the first direction;
a first lens disposed on the first base;
a first gear connected to the first base;
a second base configured to move in the first direction or the second direction;
a second lens disposed on the second base;
a second gear connected to the second base;
a support body configured to support the first base and the second base; and
an adjustment structure configured to adjust a distance between the first lens and the second lens,
wherein the adjustment structure comprises:
a lever having a rotation axis in a third direction different from the first direction and the second direction, the lever being configured to move along the rotation axis and configured to rotate about the rotation axis,
a first adjustment gear configured to be engaged with the first gear in a first position of the lever along the rotation axis;
a second adjustment gear configured to be engaged with the first gear and the second gear in a second position of the lever along the rotation axis, and
a third adjustment gear configured to be engaged with the second gear in a third position of the lever along the rotation axis.
2 . The wearable electronic device of claim 1 , wherein the first adjustment gear does not overlap the third adjustment gear when viewed along the rotation axis.
3 . The wearable electronic device of claim 2 , wherein the second adjustment gear overlaps the first adjustment gear and the third adjustment gear when viewed along the rotation axis.
4 . The wearable electronic device of claim 1 , wherein the second adjustment gear is disposed between the first adjustment gear and the third adjustment gear.
5 . The wearable electronic device of claim 4 , wherein the first adjustment gear abuts the second adjustment gear, and the second adjustment gear abuts the third adjustment gear.
6 . The wearable electronic device of claim 5 , wherein the first adjustment gear, the second adjustment gear, the third adjustment gear and the lever are integrally formed.
7 . The wearable electronic device of claim 1 ,
wherein the support body comprises:
a first side edge having a first distance from the first base; and
a second side edge having a second distance from the second base, and
wherein the lever is configured to move along the rotation axis when the first distance is substantially equal to the second distance.
8 . The wearable electronic device of claim 1 ,
wherein the support body comprises:
a first side edge having a first distance from the first base; and
a second side edge having a second distance from the second base, and
wherein the adjustment structure is configured to reduce or prevent a movement of the lever along the rotation axis when the first distance is different from the second distance.
9 . The wearable electronic device of claim 1 ,
wherein the support body comprises:
a first side edge having a first distance from the first base; and
a second side edge having a second distance from the second base, and
wherein the first adjustment gear, the second adjustment gear, or the third adjustment gear is configured to be locked to the first gear or the second gear when the first distance is different from the second distance.
10 . The wearable electronic device of claim 1 , wherein the lever comprises:
a shaft having the rotation axis, the shaft being connected to the first adjustment gear, the second adjustment gear, and the third adjustment gear; and
a handle connected to the shaft.
11 . The wearable electronic device of claim 1 , wherein the lever is disposed between the first base and the second base.
12 . The wearable electronic device of claim 1 , wherein the first base and the second base are disposed on substantially a same plane.
13 . The wearable electronic device of claim 1 , further comprising a first arm that extends or expands toward an inside of the first base,
wherein the first gear is formed at a first edge of the first arm in the first direction or the second direction.
14 . The wearable electronic device of claim 13 , wherein the first arm is disposed on a first side of each of the first adjustment gear, the second adjustment gear, and the third adjustment gear.
15 . The wearable electronic device of claim 14 , further comprising a second arm that extends or expands toward an inside of the second base,
wherein the second gear is formed at a second edge of the second arm in the first direction or the second direction.
16 . The wearable electronic device of claim 15 , wherein the second arm is disposed on a second side opposite to a first side of each of the first adjustment gear, the second adjustment gear, and the third adjustment gear.
17 . The wearable electronic device of claim 1 , wherein in the first position of the lever along the rotation axis, the first gear only engages with the first adjustment gear among the first adjustment gear, the second adjustment gear, and the third adjustment gear, and
wherein in the third position of the lever along the rotation axis, the second gear only engages with the third adjustment gear among the first adjustment gear, the second adjustment gear, and the third adjustment gear.
18 . The wearable electronic device of claim 1 , wherein the second adjustment gear overlaps with the first adjustment gear and the third adjustment gear when viewed along the rotation axis.
19 . The wearable electronic device of claim 1 , wherein the first adjustment gear, the second adjustment gear, and the third adjustment gear are arranged with respect to each other along the rotation axis.
20 . The wearable electronic device of claim 1 , wherein the the first adjustment gear, the second adjustment gear, and the third adjustment gear are configured to rotate about the rotation axis.
