- a vehicle-mounted motor (not shown) is driven by the electric power stored in the vehicle-mounted battery. Note that, during the non-contact power transmission process, necessary information exchange is performed between the power transmission device 2 and the power reception device 4 by, for example, a wireless communication device (not shown).
- the power transmission device 2 is expected to be loaded from above. For example, at the stage before power transmission, the electric propulsion vehicle 3 moves so that the power transmission device 2 and the power reception device 4 face each other. However, there is a risk that the electric propulsion vehicle 3 rides on the power transmission device 2 in the process and a large load is applied to the casing of the power transmission device 2. In particular, since the cover 5 is provided at a position facing the power transmission device 2 (arranged on the surface of the housing), a direct load is easily applied. For example, even if the power transmission device 2 is mounted on the wall surface and not stepped on by the electric propulsion vehicle 3, it is conceivable that the electric propulsion vehicle 3 comes into contact with the side and a large load is applied.
- the power transmission device 2 is required to have a strength that can withstand the load and is not easily deformed or damaged.

In addition, if the magnetic material is damaged, the support by the magnetic material may be lost, and the cover may be damaged, or the cover may be deformed and force may be applied to the coil wire, but a load support part should be provided inside the coil bobbin. This prevents the force transmitted from the cover from being applied to the magnetic body and prevents damage.

In order to perform power transmission, it is necessary that the power receiving device and the power transmission device 15 be in a positional relationship that faces each other. Therefore, the electric propulsion vehicle 16 is operated to adjust the position of the power transmission device 15 by moving the entire vehicle body. . However, a situation may occur in which the electric propulsion vehicle 16 rides on the power transmission device 15 due to an erroneous operation.

Abstract
Description
(実施の形態)
図1は、実施の形態に係る非接触電力伝送装置の送電装置の垂直断面図である。なお、本開示の非接触電力伝送装置は、磁界を発生させる送電装置15を有し、受電装置(図示せず)が、発生した磁界から電力を受電することによって、送電装置15から受電装置への非接触による電力の伝送が行われる。ここで、受電装置は、図4の電気推進車両16に搭載されるものであり、具体的には、図9に示す電気推進車両3に搭載されるような受電装置4であってもよい。
図5は、変形例1に係る非接触電力伝送装置の送電装置の垂直断面図である。本変形例では、図1の荷重支持部23を第1の荷重支持部24のみで構成している。この構成の場合、まず第1の荷重支持部24でカバー18に加わる荷重を受けることで、第1の荷重支持部24から下にかかる荷重は分散する。その後荷重は磁性体20にかかるが、磁性体20はコイル線22に比べ一般に強度が強いため、分散した荷重であれば磁性体20に荷重がかかっても破損を防ぐことが可能になる。さらに第2の荷重支持部25の存在していた領域を磁性体20で埋めることで、実施の形態1と比べて送電装置15の電力伝送効率を上げることができる。
図6は、変形例2に係る非接触電力伝送装置の送電装置の垂直断面図である。本変形例では、図1の荷重支持部23に対して、さらに第1の荷重支持部24を追加している。この構成の場合、カバー18のたわみをさらに軽減することが可能になる。
図7は、変形例3に係る非接触電力伝送装置の送電装置の垂直断面図である。本変形例では、図1の荷重支持部23の代わりに、コイルボビン21に荷重支持取り付け部26を設け、コイルボビン21とは別に設けられた荷重支持取り付け部品27を組み合わせて荷重支持部23として構成している。
図8は、変形例4に係る非接触電力伝送装置の送電装置の垂直断面図である。本変形例では、コイルボビン21をモールド材で構成し、磁性体20とコイル線22とを一体に形成している。この場合も、他の変形例と同様の効果を得ることが出来る。
