A feeding coil 11 is provided inside the housing 10. The feeding coil 11 is provided in the casing 10 so that the surface of the casing 10 and the center 19 of the feeding coil 11 are orthogonal to each other. That is, the feeding coil 11 is linearly wound so as to be parallel to the surface of the housing 10. The power feeding coil 11 plays a role of a non-contact power feeding unit in the present embodiment.

  FIG. 2 shows a specific configuration of the vehicle non-contact power feeding device 1 in the present embodiment.

  The vehicle non-contact power feeding device 1 according to this embodiment includes a housing 10, a power feeding coil 11, a camera 12, a left arm 131, a right arm 132, a central arm 133, an ECU 14, a strain gauge 15a, and a strain gauge 15b.

  The case 10 and one end of the left arm 131 are connected so that the left arm 131 can rotate with the one end as a fulcrum. Specifically, the left arm 131 is rotated by a motor and a gear (not shown). Therefore, the left arm 131 can rotate in the rotation direction 131k with one end connected to the housing 10 as a fulcrum.

  Further, the left arm 131 can be expanded and contracted in an expansion / contraction direction 131 s that is a direction along the surface of the housing 10. Specifically, the left arm 131 is expanded and contracted by a motor and a gear (not shown). Therefore, the length of the left arm 131 can be adjusted as appropriate, and the left arm 131 can be reduced without entering the housing 10. In addition, a hole 131a is present at the tip 131z which is the other end opposite to the one end of the left arm 131. The hole 131a is formed by a hole forming part 131b. When the occupant inserts a part of the portable terminal 20 into the hole 131a, the left arm 131 can support the portable terminal 20.

  The housing 10 and one end of the right arm 132 are connected so that the right arm 132 can rotate with the one end as a fulcrum. Specifically, the right arm 132 is rotated by a motor and a gear (not shown). Therefore, the right arm 132 can rotate in the rotation direction 132k with one end connected to the housing 10 as a fulcrum.

  Further, the right arm 132 can be expanded and contracted in an expansion / contraction direction 132 s that is a direction along the surface of the housing 10. Specifically, the right arm 132 is expanded and contracted by a motor and a gear (not shown). Therefore, the right arm 132 can be adjusted in length as appropriate, and can be reduced without entering the housing 10. In addition, a hole 132a is present at the tip 132z which is the other end opposite to the one end of the right arm 132. The hole 132a is formed by a hole forming part 132b. When the occupant inserts a part of the portable terminal 20 into the hole 132a, the right arm 132 can support the portable terminal 20.

  In the present embodiment, the left arm 131 and the right arm 132 correspond to a terminal support portion.

  The housing 10 and one end of the central arm 133 are connected. Further, the central arm 133 can be expanded and contracted in an expansion / contraction direction 133 s that is a direction along the surface of the housing 10. Specifically, the central arm 133 is expanded and contracted by a motor and a gear (not shown). Therefore, the length of the central arm 133 can be adjusted as appropriate, and the central arm 133 can be reduced without entering the housing 10.

  A camera 12 is provided on the central arm 133. For this reason, the camera 12 captures the mobile terminal 20 to generate an image, and the ECU 14 can detect the shape of the mobile terminal 20 using the image.

  The housing 10 contains a power supply coil 11, an ECU 14, a strain gauge 15a, and a strain gauge 15b.

  When electric power is supplied from a battery (not shown) and a current flows through the feeding coil 11, a magnetic field parallel to the center 19 of the feeding coil 11 is generated. For this reason, when the mobile terminal 20 is brought close to the housing 10 so that the center direction of the power receiving coil 21 provided in the mobile terminal 20 is parallel to the magnetic field, a current flows in the power receiving coil 21 provided in the mobile terminal 20. Will occur. Based on this current, power is supplied to the mobile terminal 20.

  The strain gauge 15a is provided in the vicinity of a location where one end of the left arm 131 and the housing 10 are connected. Therefore, when the mobile terminal 20 is installed on the left arm 131, the strain gauge 15a is distorted. And ECU14 can detect that the portable terminal 20 was installed in the left arm 131 by detecting the distortion amount of the strain gauge 15a.

  The strain gauge 15b is provided in the vicinity of a location where one end of the right arm 132 and the housing 10 are connected. Therefore, when the mobile terminal 20 is installed on the right arm 132, the strain gauge 15b is distorted. And ECU14 detects that the portable terminal 20 was installed in the right arm 132 by detecting the distortion amount of the strain gauge 15b.

  ECU14 acquires various information from the other apparatus mounted in the non-contact electric power feeder 1 for vehicles. Further, the ECU 14 controls other devices. Specifically, the ECU 14 in the present embodiment acquires an image from the camera 12 and detects the shape of the mobile terminal 20 from the acquired image. Further, the ECU 14 acquires the strain amount of the gauge from the strain gauge 15a and the strain gauge 15b.

  The ECU 14 also controls the movement of the left arm 131 in the rotational direction and the movement in the expansion / contraction direction. The ECU 14 controls the movement of the right arm 132 in the rotational direction and the movement in the expansion / contraction direction. Further, the ECU 14 controls the movement of the central arm 133 in the expansion / contraction direction.

  ECU14 in this embodiment plays the role of a shape detection part, an installation detection part, and a control part.

  FIG. 3 is a diagram of the vehicle non-contact power feeding device 1 viewed from the left arm 131 side. As shown in FIG. 3, the hole 131a is narrower on the back side, which is the side opposite to the front side, compared to the front side, which is the side where the mobile terminal 20 is inserted. Therefore, when the mobile terminal 20 is inserted into the hole 131a, any thickness of the mobile terminal 20 is supported by being sandwiched by the hole forming part 131b at any position of the hole 131a. Note that the near side is a side close to the housing 10 in the direction along the surface of the housing 10. On the other hand, the back side is a side relatively far from the housing 10 compared to the front side.

  Although illustration is omitted for simplification of explanation, the left arm has the same configuration. That is, the hole 132a is narrower on the back side, which is the opposite side to the near side, than on the near side where the mobile terminal 20 is inserted. Therefore, any thickness of the portable terminal 20 is supported by being sandwiched by the hole forming part 132b at any position of the hole 132a.

  Next, control of the vehicle non-contact power feeding device 1 when the mobile terminal 20 is installed will be described with reference to FIGS. 4 and 5.

  The ECU 14 detects the approach of the mobile terminal 20 based on the image acquired from the camera 12. Specifically, the ECU 14 performs edge detection or the like on the acquired image, and determines whether or not the ratio of the image of the mobile terminal 20 in the image is equal to or greater than a predetermined ratio.

  When the ECU 14 detects that the mobile terminal 20 is approaching, the ECU 14 detects the shape of the mobile terminal 20. Further, the ECU 14 detects the distance between the center of the mobile terminal 20 and a part of the mobile terminal 20. Specifically, the ECU 14 detects the distance between the center of the mobile terminal 20 and the lower left vertex on the left arm 131 side of the mobile terminal 20. Similarly, the distance between the center of the mobile terminal 20 and the lower right vertex on the right arm 132 side of the mobile terminal 20 is detected. It should be noted that the lower right apex is the apex in the direction closer to the driver and the lower direction in the vehicle when the mobile terminal 20 is installed in the vehicle non-contact power feeding device 1. The lower left apex is the apex in the direction far from the driver and the apex in the lower direction of the vehicle when the mobile terminal 20 is installed in the vehicle non-contact power feeding device 1.

  Then, the ECU 14 controls the left arm 131 so that the distance between the feeding coil 11 and the tip 131z of the left arm 131 matches the distance between the center of the mobile terminal 20 and the lower left vertex of the mobile terminal 20. Specifically, the ECU 14 sets the left arm 131 so that the distance between the center 19 of the power feeding coil 11 and the bottom surface of the hole forming portion 131b matches the distance between the center of the mobile terminal 20 and the lower left vertex of the mobile terminal 20. To control. Then, the ECU 14 controls the rotation direction 131k and the expansion / contraction direction 131s of the left arm 131 as shown in FIG.

  Similarly, the ECU 14 controls the right arm 132 so that the distance between the feeding coil 11 and the tip 132z of the right arm 132 matches the distance between the center of the mobile terminal 20 and the lower right vertex of the mobile terminal 20. To do. Specifically, the ECU 14 controls the rotation direction 132k and the expansion / contraction direction 132s of the right arm 132 as shown in FIG.

  For this reason, when an occupant tries to install the mobile terminal 20 in the vehicle non-contact power feeding device 1, the left arm 131 and the right arm 132 are automatically controlled according to the shape of the mobile terminal 20. For this reason, when the occupant installs the mobile terminal 20 in the vehicle non-contact power supply device 1, the positions of the center 19 of the power supply coil 11 and the center of the mobile terminal 20 automatically coincide. That is, the center 19 of the feeding coil 11 passes through the center of the mobile terminal 20. The power receiving coil 21 of the mobile terminal 20 is often provided at the center of the mobile terminal 20. Therefore, the positions of the center 19 of the power feeding coil 11 and the center of the power receiving coil 21 are automatically matched. That is, the ECU 14 automatically controls the left arm 131 and the right arm 132 so that the power supply efficiency for the mobile terminal 20 is increased.

  Further, since the left arm 131 and the right arm 132 can be extended and contracted, their respective tips can move outward from the housing 10 in a direction along the surface of the housing 10. For this reason, the left arm 131 and the right arm 132 can also be moved so that the position of the power feeding coil 11 and the power receiving coil 21 coincides with the portable terminal 20 larger than the housing 10.

  Next, when the mobile terminal 20 is installed, the strain gauge 15a and the strain gauge 15b are distorted. And ECU14 will control so that the center arm 133 may be shrunk, if the distortion of the strain gauge 15a and the strain gauge 15b is detected. When the central arm 133 is contracted, the mobile terminal 20 is held in such a manner that the mobile terminal 20 is sandwiched between the left arm 131, the right arm 132, and the central arm 133. That is, the portable terminal 20 is held with respect to the vehicle non-contact power feeding device 1 in a state where the center 19 of the power feeding coil 11 and the center of the power receiving coil 21 coincide with each other. The central arm 133 in this embodiment corresponds to a terminal fixing part.

  For this reason, even if a vehicle vibrates etc., the position of the feeding coil 11 and the receiving coil 21 does not shift | deviate. That is, the portable terminal 20 is held with respect to the vehicle non-contact power feeding device 1 in a state where the power feeding efficiency is high even when the vehicle moves.

  Further, the tip 131z of the left arm 131 is rotatable with the hinge 131h as a fulcrum as shown in FIG. Similarly, the tip of the right arm 132 is rotatable with the hinge portion 132h as a fulcrum as shown in FIG.

  As shown in FIG. 5, the portable terminal 20 is supported with respect to the vehicle non-contact power feeding device 1 at a midpoint of the hole 131a so as to be sandwiched by the hole forming part 131b. In addition, as described above, the hole 131a is narrower on the far side in the direction opposite to the near side compared to the near side on which the portable terminal 20 is inserted. Therefore, the thin portable terminal 20 is supported on the relatively back side so as to be sandwiched between the hole forming portions 131b. The thick mobile terminal 20 is supported on the relatively front side so as to be sandwiched between the hole forming portions 131b. Thus, the mobile non-contact power feeding device 1 can be supported by the mobile terminal 20 of any thickness, and the shift of the power feeding coil 11 and the power receiving coil 21 can be reduced.

  Next, a series of flows from when the portable terminal 20 is installed in the vehicle non-contact power feeding device 1 according to this embodiment to when it is removed will be described with reference to FIGS. 6 and 7.

  The process in FIG. 6 is performed for the first time when the ECU 14 is powered on. And it is performed regularly until the power supply of ECU14 is turned off. Further, this process is not performed when the mobile terminal 20 is installed on the left arm 131 and the right arm 132 which are terminal support portions.

  In step S <b> 111 of FIG. 6, the ECU 14 acquires an image from the camera 12. And ECU14 detects the approach of the portable terminal 20 using the acquired image. Thereafter, the process proceeds to step S112.

  In step S112, the ECU 14 detects the shape of the mobile terminal 20 from the acquired image. Specifically, the distance between the center of the mobile terminal 20 and a part of the mobile terminal 20 is detected. Thereafter, the process proceeds to step S113.

  In step S <b> 113, the ECU 14 controls the left arm 131 and the right arm 132 based on the detected shape of the mobile terminal 20. The specific process is as described above. Thereafter, the process proceeds to step S114.

  In step S114, the ECU 14 detects the strain amount of the strain gauge 15a and the strain gauge 15b and detects that the mobile terminal 20 is installed. Thereafter, the process proceeds to step S115.

  In step S115, the ECU 14 controls the central arm 133. Specifically, the ECU 14 performs control so that the central arm 133 is contracted toward the mobile terminal 20. Thereafter, the process ends.

  Next, the operation of the vehicle non-contact power feeding device 1 when the portable terminal 20 is removed will be described with reference to FIG.

  The process of FIG. 7 is performed for the first time when the power of the ECU 14 is turned on. And it is performed regularly until the power supply of ECU14 is turned off. Further, this process is performed when the mobile terminal 20 is installed on the left arm 131 and the right arm 132 which are terminal support portions.

  In step S <b> 121, the ECU 14 acquires an image from the camera 12. Then, the ECU 14 detects that the acquired image has a hand. Thereafter, the process proceeds to step S122.

  Next, in step S <b> 122, the ECU 14 detects whether the occupant is about to remove the mobile terminal 20 from the vehicle non-contact power feeding device 1. Specifically, ECU14 detects whether it is going to remove based on the detected hand shape. When the portable terminal 20 is removed, at least two fingers are often used. Therefore, if ECU14 detects that two fingers are extending from the acquired image, it will detect that the passenger | crew is going to remove the portable terminal 20. FIG. If the occupant intends to remove the portable terminal 20, the process proceeds to step S123, and if not, the process ends.

  In step S123, the ECU 14 controls the central arm 133. Specifically, the ECU 14 extends the central arm 133. Then, the process ends. If it does in this way, the state where portable terminal 20 is held to non-contact electric power feeder 1 for vehicles will be canceled, and a crew member can remove portable terminal 20.

  Hereinafter, the effect of the vehicle non-contact power feeding device 1 in the present embodiment will be described.

  The vehicle non-contact power feeding device 1 according to the present embodiment is a vehicle non-contact power feeding device 1 that is installed in a vehicle interior of a vehicle and can support the mobile terminal 20. The vehicle non-contact power feeding device 1 includes a housing 10 including a power feeding coil 11, an ECU 14, a left arm 131 and a right arm 132, and an ECU 14. A power supply coil 11 provided in the housing 10 supplies power to the mobile terminal 20. The ECU 14 detects the shape of the mobile terminal 20. The left arm 131 and the right arm 132 support the mobile terminal 20. Further, the ECU 14 detects the distance between the power receiving coil 21 and the left arm 131 and the right arm 132 and the distance between the power receiving coil 21 of the mobile terminal 20 and a part of the mobile terminal 20 detected based on the shape of the mobile terminal 20. Detect the difference between Then, control is performed so that the left arm 131 and the right arm 132 are moved so that the difference in distance is within a predetermined range.

  Thus, the vehicle non-contact power feeding device 1 detects the shape of the mobile terminal 20 and moves the left arm 131 and the right arm 132 that support a part of the mobile terminal 20 based on the shape. Therefore, when the occupant installs the mobile terminal 20 in the vehicle non-contact power supply device 1, the left arm 131 and the right arm 132 are arranged so that the power supply coil 11 of the housing 10 and the power reception coil 21 of the mobile terminal 20 are close to each other. Is automatically adjusted. Therefore, the vehicle non-contact power supply device 1 can efficiently supply power to the mobile terminal 20 without the passenger having to make adjustments manually.

  The left arm 131 and the right arm 132 are connected to the housing 10 at one end. Then, the other end of the left arm 131 and the right arm 132 opposite to the one end moves to the outside along the surface of the housing 10 facing the mobile terminal 20 so that the left arm 131 and the right arm 132 move outward from the housing 10. The arm 131 and the right arm 132 can extend and contract.

  In this way, the left arm 131 and the right arm 132 have a movable range outside the housing 10. Therefore, even when the mobile terminal 20 larger than the housing 10 is installed, the vehicle non-contact power feeding device 1 is arranged so that the power feeding coil 11 of the housing 10 and the power receiving coil 21 of the mobile terminal 20 are close to each other. The positions of the arm 131 and the right arm 132 can be moved.

  Further, the vehicle non-contact power feeding device 1 includes a central arm 133 that fixes the mobile terminal 20 to the housing 10. Then, the ECU 14 detects that the mobile terminal 20 is installed on the left arm 131 and the right arm 132. When the installation of the mobile terminal 20 is detected, the ECU 14 controls the central arm 133 to fix the mobile terminal 20 to the housing 10.

  If it does in this way, portable terminal 20 will be fixed to case 10 in the state where electric power feeding coil 11 of case 10 and receiving coil of portable terminal 20 adjoined. Therefore, it can prevent that the feeding coil 11 of the housing | casing 10 and the receiving coil 21 of the portable terminal 20 leave | separate by the vibration of a vehicle, etc. That is, it is possible to prevent a decrease in power supply efficiency.

  The left arm 131 includes a hole forming part 131b that forms a hole 131a into which a part of the mobile terminal 20 is inserted. The right arm 132 includes a hole forming portion 132b that forms a hole 132a into which a part of the mobile terminal 20 is inserted. The hole 131a and the hole 132a are characterized in that the back side, which is the side opposite to the front side, is narrower than the front side, which is the side where a part of the mobile terminal 20 is inserted.

  The thickness of the mobile terminal 20 varies depending on the type. If it does in this way, portable terminal 20 will be supported by being pinched in either position of hole 131a and hole 132a. That is, the left arm 131 and the right arm 132 can be supported by the mobile terminal 20 having any thickness.

(Other embodiments)

In this way, the ECU 14 can acquire the position of the center of the power receiving coil 21 in the mobile terminal 20 even if the mobile terminal 20 does not have the center of the power receiving coil 21 at the center of the mobile terminal 20. Therefore, the ECU 14 can automatically adjust the positions of the center of the power feeding coil 11 and the center of the power receiving coil 21.

  Alternatively, the ECU 14 may monitor the power supply amount of the power supply coil 11 to the portable terminal 20 and move the terminal support portion as appropriate to detect whether the power supply amount is improved. Further, the installation detection unit is the ECU 14, and whether the mobile terminal 20 is installed is detected based on the strain amounts of the strain gauge 15a and the strain gauge 15b, but is not limited thereto. For example, a proximity sensor or a pressure sensor may be used instead of the strain gauge.

  In the above embodiment, after the ECU 14 detects the approach of the mobile terminal 20, the ECU 14 controls the left arm 131 and the right arm 132 that are terminal support portions. However, the present invention is not limited to this, and the ECU 14 may control the terminal support unit after detecting that the mobile terminal 20 is installed with respect to the vehicle non-contact power feeding device 1.

  In addition, although the non-contact electric power feeding part is made into the power feeding coil 11, the power receiving part is made into the power receiving coil 21, and the non-contact electric power feeding method of an electromagnetic induction system is used, it is not restricted to this. For example, a radio wave reception method, a magnetic field resonance method, or an electric field coupling method may be used.

  In the above embodiment, the ECU 14 determines that the distance between the feeding coil 11 and the tip 131z of the left arm 131 and the distance between the center of the mobile terminal 20 and the lower left vertex of the mobile terminal 20 are the same. 131 was controlled. That is, the ECU 14 determines that the difference between the distance between the feeding coil 11 and the tip 131z of the left arm 131 and the distance between the center of the mobile terminal 20 and the lower left vertex of the mobile terminal 20 is substantially zero. Made the control. However, this difference in distance may be allowed as long as it is within a predetermined range. Furthermore, the ECU 14 may control the left arm 131 so that the difference in distance decreases.

  Further, in the above embodiment, the ECU 14 causes the distance between the center 19 of the power supply coil 11 and the bottom surface of the hole forming portion 131b to match the distance between the center of the mobile terminal 20 and the lower left vertex of the mobile terminal 20. The left arm 131 was controlled. However, the present invention is not limited to this, and the ECU 14 determines the distance between a part of the feeding coil 11 and a part of the left arm 131 and the distance between a part of the power receiving coil 21 and a part of the mobile terminal 20. And may be controlled to match. That is, the ECU 14 may control the terminal support portion so that the distance between the center 19 of the power feeding coil 11 and the center of the power receiving coil 21 matches.
