Abstract

A holder for holding a charged device. The charged device includes a secondary coil that induces power based on a change in magnetic flux from a primary coil. The holder includes a case that accommodates the primary coil. Movable portions are movably held by the case. The movable portions are movable relative to the case. Each of the movable portions includes a first end located in the case and a second end located outside the case. A holding portion is formed on the second end of each movable portion. The holding portions contact side surfaces of the charged device to surround and hold the charged device.

Claims

1. A holder for holding a charged device, wherein the charged device includes a secondary coil that induces power based on a change in magnetic flux from a primary coil, the holder comprising:

a case that accommodates the primary coil;

a plurality of movable portions movably held by the case, wherein the movable portions are movable relative to the case, and each of the movable portions includes a first end located in the case and a second end located outside the case; and

a plurality of holding portions, each formed on the second end of each of the movable portions, wherein the holding portions contact side surfaces of the charged device to surround and hold the charged device.

2. The holder according to claim 1, further comprising at least one stopper that stops movement of at least one of the movable portions in the case, and allows for the holding portion corresponding to the at least one movable portions to move relative to the case when force of a predetermined value or greater is applied to the holding portion or the case.

3. The holder according to claim 1, wherein

the charged device includes two parallel first side surfaces, which extend in a first direction, and two parallel second side surfaces, which extend in a second direction that is orthogonal to the first direction;

and

the holding portions include

two first holding portions that move along the first direction and respectively contact the two second side surfaces, and

two second holding portions that move along the second direction and respectively contact the two first side surfaces.

4. A wireless charging device for charging a charged device including a secondary coil, the wireless charging device comprising:

an excitation circuit;

a primary coil that forms magnetic flux when excited by current from the excitation circuit to induce power at the secondary coil; and

a holder that holds the charged device, wherein the holder includes

a case that accommodates the primary coil,

a plurality of movable portions movably held by the case, wherein the movable portions are movable relative to the case, and each of the movable portions includes a first end located in the case and a second end located outside the case, and

a plurality of holding portions, each formed on the second end of each of the movable portions, wherein the holding portions contact side surfaces of the charged device to surround and hold the charged device.

5. The wireless charging device according to claim 4, wherein the holder further includes at least one stopper that stops movement of at least one of the movable portions in the case, and allows for the holding portion corresponding to the at least one movable portions to move relative to the case when force of a predetermined value or greater is applied to the holding portion or the case.

6. The wireless charging device according to claim 4, wherein

the charged device includes two parallel first side surfaces, which extend in a first direction, and two parallel second side surfaces, which extend in a second direction that is orthogonal to the first direction;

and

the holding portions include

two first holding portions that move along the first direction and respectively contact the two second side surfaces, and

two second holding portions that move along the second direction and respectively contact the two first side surfaces.
