20140055089 | POWER RECEPTION DEVICE, POWER TRANSMISSION DEVICE AND POWER TRANSFER SYSTEM - A power reception device comprising: a shield including a main surface portion and a circumferential wall portion connected to a circumferential edge of the main surface portion, and having an opening in a position opposite to the main surface portion; a lid portion formed to cover the opening; a mounted resonant portion arranged within the shield, and resonating, through an electromagnetic field, with a facility-side resonant portion provided in an external facility; and a holding portion connecting the lid portion and the main surface portion, and supporting the mounted resonant portion. | 02-27-2014 |
20140111002 | POWER RECEPTION DEVICE, POWER TRANSMISSION DEVICE AND POWER TRANSFER SYSTEM - A power reception device includes: a vehicle-side resonant portion mounted on a vehicle and resonating, through an electromagnetic field, with a facility-side resonant portion provided in an external facility; and a vehicle-side support including a first support member supporting the vehicle-side resonant portion, and a second support member spaced apart from the vehicle-side resonant portion and supporting the first support member, wherein a dielectric tangent of the first support member is smaller than a dielectric tangent of the second support member. | 04-24-2014 |
20140232202 | POWER RECEPTION DEVICE, POWER TRANSMISSION DEVICE AND POWER TRANSFER SYSTEM - A power reception device includes a power reception unit configured to receive power in a non-contact manner from a power transmission unit, and a first holding unit configured to hold the power reception unit. The power reception unit includes a power reception coil, and the power reception coil is formed by winding a first coil wire which has a width greater than a thickness thereof. The first holding unit includes a plurality of first coil holding members each formed with a first groove which extends in an extending direction of the power reception coil and receives the power reception coil. At least a part of the first groove is formed in such a way that a depth of the first groove extending in a width direction of the first coil wire is greater than a width of the first groove extending in a thickness direction of the first coil wire. | 08-21-2014 |
20140285029 | NON-CONTACT ELECTRIC POWER RECEPTION DEVICE, NON-CONTACT ELECTRIC POWER TRANSMISSION DEVICE, AND NON-CONTACT ELECTRIC POWER TRANSMISSION AND RECEPTION SYSTEM - The non-contact electric power reception device includes an electric power reception portion and an electric load device. The electric power reception portion is configured such that best transmission efficiency at a power supply frequency of the power supply portion used for non-contact electric power transmission is achieved when the electric power reception portion is arranged with its position being displaced from a position of the electric power transmission portion. Preferably, the electric power reception portion is configured such that a peak frequency at which transmission efficiency at the time of change in power transmission frequency exhibits a peak and a power supply frequency match with each other when the electric power reception portion is arranged with positions in a horizontal direction of a central axis of the electric power reception portion and a central axis of the electric power transmission portion being displaced from each other. | 09-25-2014 |
20140305722 | VEHICLE - This vehicle includes a vehicle-mounted component mounted below a rear floor panel and an electric power reception device mounted below the rear floor panel and including an electric power reception portion receiving electric power in a non-contact manner from an electric power transmission device including an externally provided electric power transmission portion, and the vehicle-mounted component is arranged flush with and around the electric power reception device. | 10-16-2014 |
20140354068 | POWER RECEPTION DEVICE, POWER TRANSMISSION DEVICE, AND POWER TRANSFER SYSTEM - A power reception device includes a power reception unit having a first capacitor, receiving electric power in a non-contact manner from an externally provided power transmission unit, a first housing case housing the power reception unit inside, and a first anchor member anchoring the first capacitor. The first housing case includes a first shield defining a region where an electromagnetic field developed around the power reception unit is emitted. The first capacitor is anchored by the first anchor member at a position spaced apart from the first shield. | 12-04-2014 |
20140361635 | CONTACTLESS FEED SYSTEM AND SHIELD CASE FOR THE SAME - There is provided a shield case allowing efficient power delivery while ensuring environmental resistant such as strength and waterproof and provided a contactless feed system using the shield case. | 12-11-2014 |
