Abstract
Official abstract text for this publication.
Some embodiments include a coil positioning device for a wireless charging system comprising: a movable coil unit with a first coil; and a drive mechanism coupled to the movable coil unit to move the movable coil unit into a charging position with respect to a second coil. The drive mechanism comprises a motor and a converter mechanism for transferring an output generated by the motor to the movable coil unit to generate a multidimensional movement of the movable coil unit.
First claim
Opening claim text (preview).
What is claimed is: 1. A coil positioning device for a wireless charging system, the device comprising: a movable coil unit with a first coil; and a drive mechanism coupled to the movable coil unit to move the movable coil unit into a charging position with respect to a second coil; wherein the drive mechanism comprises a motor and a converter mechanism for transferring an output generated by the motor to the movable coil unit to generate a multidimensional movement of the movable coil unit; the converter mechanism comprises a force transfer device transferring an output of the motor to the movable coil unit; the output of the motor is applied on the force transfer device at a first force application point; force is transferred from the force transfer device to the movable coil unit at a second force application point; and a distance between the first force application point and the second force application point is varied by operation of the converter mechanism; the force transfer device is fixed to an output element of the motor; and the movable coil unit is coupled to the force transfer device to move relative to the output element in a direction differing from a movement direction of the output element; the force transfer device comprises an elongate element having a straight groove; and the movable coil unit slides in the groove. 2. The coil positioning device according to claim 1 , wherein the converter mechanism comprises a guiding device having a multidimensional movement path for the movable coil unit. 3. The coil positioning device according to claim 2 , wherein: the guiding device comprises a guiding plate with a guiding groove extending along a multidimensional path; and the movable coil unit is at least partially accommodated in the guiding groove. 4. The coil positioning device according to claim 3 , wherein the multidimensional path is at least partially curved. 5. The coil positioning device according to claim 1 , wherein the motor comprises a rotating output element. 6. The coil positioning device according to claim 1 , further comprising a communication device for data exchange, the communication device configured to move synchronous with the movable coil unit. 7. The coil positioning device according to claim 1 , wherein the first coil is an emitting coil.
