Device cradle
Provided is a device cradle. The device cradle includes a fixer for fixing a device, a body portion including a main body and a penetrating groove which is formed to penetrate the main body from a top surface of the main body and accommodates at least a portion of the fixer, and a first driving portion for rotating the fixer by a specified angle around a horizontal axis with respect to the body portion, wherein the penetrating groove has a spherical shape, and wherein at least part of the fixer may be formed in a spherical shape.
1. A device cradle, comprising:
a fixer configured to fix a device;
a body portion comprising a main body and a penetrating groove formed to penetrate from a top surface of the main body and accommodating at least a portion of the fixer, wherein at least part of the fixer exposed to an outside the body portion is formed in a spherical shape; and
a first driving portion connected to a flat surface of inside the fixer accommodated in the penetrating groove and configured to tilt the flat surface by a specified angle around a horizontal axis with respect to the body portion,
wherein the penetrating groove is formed in a circular shape, and
an area of the fixer accommodated in the penetrating groove changes as the flat surface of inside the fixer is tilted by the first driving portion.
2. The device cradle of claim 1 , wherein the first driving portion comprises a motor configured to generate a torque and at least one gear configured to transmit the torque.
3. The device cradle of claim 2 , wherein the first driving portion comprises:
a first gear;
a first motor fixed to the main body and configured to rotate the first gear around the horizontal axis; and
a connecting member disposed between the first gear and fixer and configured to transmit, to the fixer, the torque transmitted from the first gear.
4. The device cradle of claim 3 , wherein the connecting member has a tooth formed on one side thereof to be connected to the first gear,
wherein another side thereof is formed flat to be connected to the fixer.
5. The device cradle of claim 1 , wherein the main body comprises:
a first body; and
a second body disposed on the first body,
the device cradle further comprising:
a second driving portion configured to rotate the second body by a specified angle around a vertical axis with respect to the first body.
6. The device cradle of claim 5 , wherein the second driving portion comprises:
a motor configured to generate torque and at least one gear configured to transmit the torque.
7. The device cradle of claim 6 , wherein the second driving portion comprises:
a first rotating portion fixed to the first body;
a second rotating portion fixed to the second body and having a tooth formed on an inner circumferential surface;
a worm;
a second motor fixed to the first rotating portion and configured to rotate the worm around the horizontal axis;
a worm wheel connected to the worm by a worm gear method and configured to rotate around the vertical axis; and
at least one second gear configured to rotate around the vertical axis, disposed between the worm wheel and the tooth formed on the inner circumferential surface of the second rotating portion, and configured to transmit, to the second rotating portion, the torque transmitted from the worm wheel.
8. Device cradle of claim 1 , wherein the fixer comprises:
a fixing frame;
a fixing groove formed to be recessed from one side of the fixing frame;
a gripping member disposed inside the fixing groove and configured to grip the device; and
a distance adjusting portion configured to adjust a fixed distance which is a distance between one side of the fixing groove and the gripping member.
9. The device cradle of claim 8 , wherein the distance adjusting portion is connected to the gripping member, penetrating the fixing frame, and connected to the fixing frame via thread-connection,
wherein the fixed distance is adjusted as the distance adjusting portion rotates around a rotation axis.
