Description

[Technical field]

[0001] The present disclosure relates to an in-vehicle contactless power supply device. [Background technology]

[0002] Conventionally, there is known an in-vehicle power supply device that is mounted on a vehicle and can charge an object to be charged. The power supply device described in Patent Document 1 (a device mounting unit in Patent Document 1) is not for in-vehicle use, but is configured to be capable of contactless power supply to a plurality of devices mounted on the same plane of a mounting stand. This power supply device can simultaneously supply power to a plurality of devices, and can group the devices and specify the charging order for the devices in the group.

[0003] The power supply device described in Patent Document 2 (portable electronic device in Patent Document 2) is not for vehicle mounting, but has multiple slots that can charge multiple battery packs simultaneously, and supplies power by contacting battery pack connection terminals arranged on the battery packs with inner connection terminals arranged in the slots. The slots have covers that can be opened and closed to prevent the battery packs from falling off, and charging priorities can be assigned. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2014-023253 A [Patent Document 2] JP 2004-207137 A Summary of the Invention [Problem to be solved by the invention]

[0005] The power supply devices described in Patent Documents 1 and 2 are capable of simultaneously supplying power to multiple power-receiving objects, and are also capable of assigning a power supply order. However, when multiple power-receiving objects are supplied with power at the same time, the power supply capacity for each power-receiving object decreases, and the power supply time becomes longer. In order to prevent the power supply time from becoming longer, if the maximum output capacity of the power supply circuit is increased or multiple power supply circuits are provided according to the number of power-receiving objects to be supplied with power at the same time, the cost of the power supply device increases, and the space required for arranging the power supply circuits increases, resulting in a larger size of the power supply device itself.

[0006] The in-vehicle contactless power supply device used in the vehicle cabin is sufficient if it can charge at least one powered object, and the function of simultaneously supplying power to multiple powered objects may be omitted in consideration of costs and installation space. However, since the method of placing the powered object in a position where it can be supplied with power contactlessly differs depending on the specifications, an in-vehicle contactless power supply device that is compatible with only the specifications of one powered object may not be able to charge powered objects of other specifications.

[0007] Therefore, there is a demand for an in-vehicle contactless power supply device capable of charging power supply devices of a plurality of specifications. [Means for solving the problem]

[0008] One embodiment of an in-vehicle contactless power supply device according to the present disclosure is an in-vehicle contactless power supply device that is mounted on a vehicle and supplies power contactlessly to a rectangular plate-shaped power supply object having a secondary battery inside, the contactless power supply device comprising: a first mounting section having a first mounting surface to which power can be supplied when the power supply object is placed, a second mounting section having a second mounting surface to which power can be supplied when the power supply object is placed, and a contactless power supply section having a first coil section arranged on a first back surface opposite to the first mounting surface and a second coil section arranged on a second back surface opposite to the second mounting surface, the contactless power supply section selectively supplying power to either the first coil section or the second coil section to generate a magnetic flux, the first mounting surface and the second mounting surface being non-parallel to each other.

[0009] According to this embodiment, since the non-contact power supply unit is configured to supply power only to either the first or second placement unit, there is no need to increase the output capacity of the non-contact power supply unit or to provide two non-contact power supply units in order to simultaneously supply power to the power-receiving objects placed on the two placement units. In addition, since the first and second placement surfaces are non-parallel and arranged three-dimensionally, the in-vehicle non-contact power supply device can be made smaller in size and the occupied area can be narrower than when they are arranged on the same plane.

[0010] In another embodiment of an in-vehicle contactless power supply device according to the present disclosure, the contactless power supply unit has a magnet that is disposed on the second back surface and that positions and fixes the power-supplied object by magnetic attraction.

[0011] Since the non-contact power supply unit has a magnet on the second back surface, the second mounting section can be made compatible with magnet alignment, eliminating the need for a complex mechanism for placing the power-receiving object in a position where it can be placed. In addition, if it is compatible with magnet alignment, there is no need to provide a separate structure to prevent the power-receiving object from moving from the second mounting surface, so the second mounting section can be simplified, making it easier to match the design of the in-vehicle non-contact power supply device to the concept of the vehicle interior.

[0012] In another embodiment of the in-vehicle contactless power supply device of the present disclosure, the first coil section has multiple coils, and the multiple coils are arranged with their central axes all perpendicular to the first mounting surface and spaced apart from each other.

[0013] According to this embodiment, the first coil section has a plurality of coils arranged therein, and when the power-receiving object does not support magnet alignment, the first mounting section can supply power to the power-receiving object. The power-receiving object that does not support magnet alignment can also be supplied with power by the second mounting section, but in that case, there is a risk that the power-receiving object placed on the second mounting surface will slip off the second mounting surface and jump out into the vehicle due to inertial force when the vehicle turns around a curve or brakes suddenly while driving.

[0014] In addition, the first coil section is composed of multiple coils, and the central axes of each coil are all perpendicular to the first mounting surface and arranged at a distance from each other. Therefore, when the sizes of the powered objects are different, if a coil that has good power supply efficiency to the secondary coil built into the powered object can be selected from the multiple coils, power can be efficiently supplied to the powered object even if it does not support magnet alignment.

[0015] In another embodiment of the in-vehicle contactless power supply device according to the present disclosure, the second mounting portion has a recess adjacent to the second mounting surface and recessed toward the second coil portion from the second mounting surface.

[0016] According to this embodiment, when the second mounting portion has a recess that is recessed toward the second coil portion relative to the second mounting surface, even if the powered object has a part (e.g., part of the camera unit) that protrudes from the surface that contacts the second mounting surface, by facing this protruding part to the recess, it is possible to prevent a decrease in the efficiency of power supply to the powered object or a state in which power cannot be supplied.

[0017] In another embodiment of the in-vehicle contactless power supply device of the present disclosure, the first mounting portion has a pair of first walls erected from a pair of first edge portions of the first mounting surface on the side opposite to the side on which the first coil portion is arranged, and the distance between the narrowest points of the pair of first walls is longer than the length of the short side of the power supply object placed on the second mounting surface with the power receiving surface in contact with the first mounting surface and shorter than the length of the long side.

[0018] According to this embodiment, the powered object can only be placed on the narrowest part of the pair of first walls of the first mounting part with its longitudinal portion aligned along the first walls, so the powered object can be placed on the first mounting surface so that the secondary coil built into the powered object is optimally positioned relative to the first coil portion.

[0019] In another embodiment of an in-vehicle contactless power supply device according to the present disclosure, the first mounting portion has a bottom wall that connects a pair of the first walls and stands upright, and supports the power-supplied object when the power-supplied object is placed on the first mounting surface.

[0020] According to this embodiment, the bottom wall supporting the power-supplied object can position the power-supplied object on the first placement surface.

[0021] In another embodiment of the in-vehicle contactless power supply device of the present disclosure, the second mounting portion has a pair of second walls erected on the side of the second mounting surface opposite the side on which the second coil portion is arranged, and the distance between the points where the pair of second walls intersect with the same imaginary plane as the second mounting surface is longer than the length of the short side of the power supply object placed on the second mounting surface with the power receiving surface in contact with the second mounting surface and shorter than the length of the long side.

[0022] According to this embodiment, the powered object can only be placed on the second mounting portion in a direction in which the longitudinal portion of the powered object is aligned with the second wall, so the powered object can be placed on the second mounting surface so that the secondary coil built into the powered object is in an optimal position relative to the second coil portion.

[0023] In another embodiment of an in-vehicle contactless power supply device according to the present disclosure, when the powered object is placed on the first mounting surface, at least a portion of the powered object protrudes toward the second mounting surface, making it impossible to place another powered object on the second mounting surface.

[0024] According to this embodiment, when a powered object is placed on the first mounting surface, another powered object cannot be placed on the second mounting surface, thereby preventing the mistake of placing another powered object on the second mounting section and attempting to charge it while power is being supplied to the powered object on the first mounting section.

[0025] In another embodiment of an in-vehicle contactless power supply device according to the present disclosure, when the powered object is placed on the second mounting surface, at least a portion of the powered object protrudes toward the first mounting surface, making it impossible to place another powered object on the first mounting surface.

[0026] According to this embodiment, when a powered object is placed on the second mounting surface, another powered object cannot be placed on the first mounting surface, thereby preventing the mistake of placing another powered object on the first mounting section and attempting to charge it while power is being supplied to the powered object on the second mounting section.

[0027] In another embodiment of an in-vehicle contactless power supply device according to the present disclosure, the first mounting portion has a storage portion that forms a space capable of accommodating the powered object, the storage portion having the first mounting surface, a pair of first walls erected on the side of the first mounting surface opposite the side on which the first coil portion is arranged, a bottom wall erected to connect the pair of first walls and supporting the powered object when the powered object is placed on the first mounting surface, a top wall facing the first mounting surface and in contact with the pair of first walls and the bottom wall, and an opening through which the powered object is inserted, the storage portion being positioned such that when the powered object is placed on the second mounting portion, at least a portion of the opening is blocked, thereby making it impossible to place another powered object on the first mounting surface.

[0028] According to this embodiment, when the powered object is placed on the second mounting surface, at least a portion of the opening is blocked, making it impossible to place another powered object on the first mounting surface. This prevents the mistake of attempting to charge an object by placing another powered object on the first mounting section while power is being supplied to the object on the second mounting section.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0030] Hereinafter, an embodiment of an in-vehicle contactless power supply device according to the present disclosure will be described in detail with reference to the drawings. Note that the embodiments described below are examples for explaining the in-vehicle contactless power supply device, and the in-vehicle contactless power supply device is not limited to these embodiments. Therefore, the in-vehicle contactless power supply device according to the present disclosure can be embodied in various forms without departing from the gist of the device.

[0031] [First embodiment] [Configuration of in-vehicle contactless power supply device] 1, an in-vehicle contactless power supply device 1 according to the first embodiment is incorporated in a center console 3 located between a driver's seat and a passenger seat in a vehicle cabin of a vehicle 2. A known method can be used for fixing the in-vehicle contactless power supply device 1 to the center console 3. For example, the in-vehicle contactless power supply device 1 manufactured separately may be directly fixed to the center console 3, the center console 3 and a housing H (see FIG. 2) of the in-vehicle contactless power supply device 1 may be integrally formed, or other methods may be used for fixing.

[0032] As shown in Fig. 2 to Fig. 6, the in-vehicle contactless power supply device 1 is composed of a housing H and a contactless power supply section 30. The housing H includes a first mounting section 10 and a second mounting section 20, which will be described later. In the in-vehicle contactless power supply device 1 of this embodiment, a rectangular plate-shaped first mobile information terminal 7 (an example of a power-supplied object) such as a smartphone is mounted on the first mounting section 10 for charging. Also, a rectangular plate-shaped second mobile information terminal 8 (an example of a power-supplied object) which is a smartphone with specifications different from those of the first mobile information terminal 7 is mounted on the second mounting section 20 for charging.

[0033] 1, in this embodiment, in each of the in-vehicle contactless power supply device 1 and the vehicle 2 in a state in which the in-vehicle contactless power supply device 1 is fixed to the center console 3 of the vehicle 2, a direction parallel to and the same as the traveling direction of the vehicle 2 is referred to as the Y1 direction, and a direction parallel to and the same as the backward direction of the vehicle 2 is referred to as the Y2 direction, and the Y1 direction and the Y2 direction are collectively referred to as the Y direction. Also, in each of the in-vehicle contactless power supply device 1 and the vehicle 2 in a state in which the in-vehicle contactless power supply device 1 is fixed to the center console 3 of the vehicle 2, a relative front side is referred to as the Y1 side, and a relative rear side is referred to as the Y2 side.

[0034] Similarly, in each of the in-vehicle non-contact power supply device 1 and the vehicle 2 in a state in which the in-vehicle non-contact power supply device 1 is fixed to the center console 3 of the vehicle 2, a direction parallel to the left-right direction toward the traveling direction of the vehicle 2 and the same as the right direction of the vehicle 2 is referred to as the X1 direction, and a direction parallel to the left-right direction and the same as the left direction of the vehicle 2 is referred to as the X2 direction, and the X1 direction and the X2 direction are collectively referred to as the X direction. Also, in each of the in-vehicle non-contact power supply device 1 and the vehicle 2 in a state in which the in-vehicle non-contact power supply device 1 is fixed to the center console 3 of the vehicle 2, the relative right side is referred to as the X1 side, and the relative left side is referred to as the X2 side.

[0035] Furthermore, in each of the in-vehicle contactless power supply device 1 and the vehicle 2 in a state in which the in-vehicle contactless power supply device 1 is fixed to the center console 3 of the vehicle 2, a direction parallel to the vertical direction of the vehicle 2 (direction perpendicular to the X direction and the Y direction) and the same as the upper direction of the vehicle 2 is referred to as the Z1 direction, and a direction the same as the lower direction of the vehicle 2 is referred to as the Z2 direction, and the Z1 direction and the Z2 direction are collectively referred to as the Z direction. Furthermore, in each of the in-vehicle contactless power supply device 1 and the vehicle 2 in a state in which the in-vehicle contactless power supply device 1 is fixed to the center console 3 of the vehicle 2, a relative upper side is referred to as the Z1 side, and a relative lower side is referred to as the Z2 side.

[0036] 2 to 6, the housing H is made of resin or a composite of resin and metal, and has a generally rectangular parallelepiped shape having four sides including a top wall H1 parallel to the XY plane and located on the Z1 side, a pair of side walls H2 parallel to the YZ plane and located on the X1 and 2 sides, and a rear wall H3 parallel to the XZ plane and located on the Y2 side. There are no walls on the Z2 and Y1 sides. Depending on the method of fixing the in-vehicle non-contact power supply device 1 to the center console 3, the side wall H2 and the rear wall H13 may be omitted, or there may be walls on the Z2 and / or Y1 sides. The inside of the housing H is hollow, and a non-contact power supply unit 30 described later is attached thereto.

[0037] A first mounting portion 10 and a second mounting portion 20 are arranged on an upper wall H1 of the housing H. The first mounting portion 10 is arranged on the Y1 side of the upper wall H1, and the second mounting portion 20 is arranged adjacent to the first mounting portion 10 on the Y2 side.

[0038] The first placement portion 10 is disposed on the Z2 side with respect to a concave surface 25a recessed from the upper surface H11 of the upper wall H1 toward the Z2 side. The concave surface 25a is parallel to the XY plane. The first placement portion 10 includes a first placement surface 11, a pair of first walls 13, a bottom wall 14, and a top wall 15. The first placement surface 11 is disposed inclined toward the Z2 side by a first angle θ1 with respect to the Y1 direction (see FIG. 5). In this embodiment, the first angle θ1 is, for example, 20 degrees. When viewed along the Z direction, the first placement surface 11 has a pair of first long edge portions 11a (an example of a first edge portion) extending in the Y direction and a pair of first short edge portions 11b extending in the X direction. When the first placement surface 11 is viewed from a direction perpendicular to the first placement surface 11, the shortest length between the pair of first long edge portions 11a is longer than the shortest length between the pair of first short edge portions 11b.

[0039] The pair of first walls 13 are erected from each of the pair of first long edge portions 11a on the opposite side to the side where the first coil portion 31 described later is arranged. That is, the pair of first walls 13 face each other. Specifically, the pair of first walls 13 are erected perpendicular to the first mounting surface 11 and are parallel to each other. The first mounting surface 11 may be rectangular in shape, with the first long edge portion 11a being a straight line parallel to the Y direction and the first short edge portion 11b being a straight line parallel to the X direction. In that case, the first interval d1, which is the interval between the pair of first walls 13, is constant regardless of location and is equal to the length of the first short edge portion 11b of the first mounting surface 11. The bottom wall 14 is erected from the first short edge portion 11b on the Y1 side of the first mounting surface 11 to connect the pair of first walls 13 in a direction perpendicular to the first mounting surface 11. 5, the height of the bottom wall 14 from the first mounting surface 11 is slightly higher than the thickness (plate thickness) of the first mobile information terminal 7. Furthermore, the top wall 15 stands upright so as to face the first mounting surface 11 and to contact the pair of first walls 13 and the bottom wall 14. At least a part of the first mobile information terminal 7 is accommodated in a first housing section 16 (an example of a housing section) formed by the first mounting surface 11, the pair of first walls 13, the bottom wall 14, and the top wall 15. The opposite side (the second mounting section 20 side) of the bottom wall 14 of the first housing section 16 is a first opening 17 (an example of an opening), and the first mobile information terminal 7 is accommodated in the first housing section 16 from the first opening 17 and placed on the first mounting surface 11.

[0040] The first distance d1 is longer than the length of the short side 7b of the rectangular plate-like first portable information terminal 7 that can be placed on the first placement section 10 for charging, and shorter than the length of the long side 7a (see FIG. 3). Therefore, when the first portable information terminal 7 is accommodated in the first housing section 16 and placed on the first placement surface 11, the first portable information terminal 7 can only be placed in a position where the long side 7a of the first portable information terminal 7 is aligned with the first wall 13. When the first portable information terminal 7 is accommodated in the first housing section 16, the first portable information terminal 7 is in contact with the first placement surface 11 and the bottom wall 14. Furthermore, since the shortest length between the pair of first short edges 11b of the first mounting surface 11 is shorter than the length of the long portion 7a of the power receiving surface of the first mobile information terminal 7, when the first mobile information terminal 7 is accommodated in the first accommodation section 16, at least the end opposite the side in contact with the bottom wall 14 of the first mobile information terminal 7 protrudes toward the second mounting section 20 more than the first mounting surface 11.

[0041] As shown in FIG. 2, the second mounting portion 20 includes a second mounting surface 21 and a recess 25. The recess 25 includes a second wall 23, a recess 25a, and a third wall 26. The second wall 23 is a wall formed on the upper wall H1 so as to connect the upper surface H11 and the recess 25a over the entire circumference. That is, the first mounting portion 10 and the second mounting surface 21 are disposed on the inner circumferential side of the second wall 23. The second wall 23 can be shaped to be inclined in a direction such that the circumferential length on the recess 25a side is shorter than the circumferential length on the upper surface H11 side.

[0042] The second mounting surface 21 is formed to protrude from the concave surface 25a to the Z1 side. In other words, the recess 25 including the concave surface 25a is recessed toward the Z2 side from the second mounting surface 21. The second mounting surface 21 is parallel to the XY plane and is located on the Z2 side from the upper surface H11 of the upper wall H1 (see FIG. 6). That is, when the concave surface 25a is used as a reference, the protrusion amount of the second mounting surface 21 toward the Z1 side is smaller than the protrusion amount of the upper surface H11 toward the Z1 side. The second mounting surface 21 has a pair of second long edge portions 21a extending in the X direction and a pair of second short edge portions 21b (an example of a second edge portion) extending in the Y direction. The pair of second long edge portions 21a may have the same shape or different shapes. The second mounting surface 21 may be rectangular in shape, with the second long edge 21a being a straight line parallel to the X direction and the second short edge 21b being a straight line parallel to the Y direction, and the shortest length between the pair of second short edges 21b may be longer than the shortest length between the second long edges 21a. The second mounting surface 21 is adjacent to the first mounting surface 11, and the second mounting surface 21 and the first mounting surface 11 are non-parallel, and the first mounting surface 11 is inclined by θ1 with respect to the second mounting surface 21. The second long edge 21a on the first mounting surface 11 side of the second mounting surface 21 and the first short edge 11b on the first mounting surface 21 side of the first mounting surface 11 overlap and are the same part. That is, the lengths of the second long edge 21a and the first short edge 11b in the X direction are equal.

[0043] The third wall 26 is formed between the concave surface 25a and the pair of second short edge portions 21b and the second long edge portion 21a other than the second long edge portion 21a in contact with the first mounting surface 11, among the pair of second long edge portions 21a. That is, the third wall 26 is formed in three directions. The third wall 26 may be inclined from the second mounting surface 21 toward the concave surface 25a.

[0044] In the second wall 23, portions extending in the Y direction are referred to as a pair of opposing walls 23a. Hereinafter, the distance between the points of the pair of opposing walls 23a that intersect with the same imaginary plane S as the second placement surface 21 is referred to as a second distance d2 (see FIG. 3).

[0045] The second interval d2 is longer than the length of the short side 8b and shorter than the length of the long side 8a of the second portable information terminal 8, which is a rectangular plate-like terminal that can be placed on the second placement section 20 and charged. Therefore, when placing the second portable information terminal 8 on the second placement surface 21, the second portable information terminal 8 can be placed only in a position where the long side 8a of the second portable information terminal 8 is aligned with the second wall 23. In other words, even if an attempt is made to place the second portable information terminal 8 on the second placement surface 21 in a position where the short side 8b of the second portable information terminal 8 is parallel to the Y direction, the short side 8b of the second portable information terminal 8 and the opposing wall 23a of the second wall 23 interfere with each other, and the second portable information terminal 8 cannot be placed.

[0046] Next, the non-contact power supply unit 30 will be described with reference to Fig. 3 to Fig. 6. The non-contact power supply unit 30 is attached to the first back surface 11c, which is the back side of the first mounting surface 11 of the first mounting unit 10, and when operated, supplies power in a non-contact manner to either a secondary battery (not shown) built in the first mobile information terminal 7 placed on the first mounting surface 11 or a secondary battery (not shown) built in the second mobile information terminal 8 placed on the second mounting surface 21. Specifically, for the first mobile information terminal 7, a magnetic field is generated by passing current through the primary coil of the first coil section 31 of the non-contact power supply unit 30 arranged to face the first back surface 11c, and the generated magnetic field generates an induced electromotive force in a secondary coil (not shown) built in the first mobile information terminal 7 (electromagnetic induction). The secondary battery of the first mobile information terminal 7 is charged by the induced electromotive force of this secondary coil (see Fig. 5). Similarly, for the second portable information terminal 8, a magnetic field is generated by passing current through the primary coil of the second coil section 32 of the non-contact power supply section 30 arranged so as to face the second back surface 21c, which is the back side of the second placement surface 21, and the generated magnetic field generates an induced electromotive force in a secondary coil (not shown) built into the second portable information terminal 8 (electromagnetic induction). The secondary battery of the second portable information terminal 8 is charged by the induced electromotive force of this secondary coil (see FIG. 6). Hereinafter, generating an induced electromotive force in each of the secondary coils of the first portable information terminal 7 and the second portable information terminal 8 is also referred to as "supplying power".

[0047] As shown in Figs. 3 to 6, the non-contact power supply unit 30 includes a first coil unit 31, a first sheet 31a, a second coil unit 32, a second sheet 32a, a substrate 33, a first upper shield case 34a, a first lower shield case 34b, a connector 35, a first upper case 36a, a first lower case 36b, a magnet 37, and a second case 39. A charging circuit and a control circuit for controlling the non-contact power supply are mounted on the substrate 33. The first coil unit 31 faces the first back surface 11c, and the second coil unit 32 faces the second back surface 21c, which is the back side of the second mounting surface 21 of the second mounting unit 20. All three primary coils are hollow-core annular plate-shaped coils, and are arranged such that the central axis A of each coil is perpendicular to the first mounting surface 11 and is spaced apart from each other. Each coil may be arranged such that its central axis A is linear along the Y direction.

[0048] The first coil section 31 has a plurality of primary coils (three in this embodiment) arranged therein, stacked in close contact with each other with one primary coil located closer to the first rear surface 11c and two primary coils located farther from the first rear surface 11c. The three primary coils of the first coil section 31 are electrically connected to the substrate 33. Hereinafter, the three primary coils will be collectively referred to as the first coil section 31.

[0049] The first upper shield case 34a is formed by bending a plate made of a material with high electromagnetic wave shielding performance such as iron, and has a wall around the first coil section 31. The first coil section 31 is fixed to a first sheet 31a of a magnetic absorber made of a dielectric material by adhesion or other methods, and the first sheet 31a is fixed to the first upper shield case 34a by adhesion or other methods. That is, the first coil section 31, the first sheet 31a, and the first upper shield case 34a are laminated in this order and integrated. By providing the first sheet 31a, it is possible to control the magnetic field generated by the current flowing through the first coil section 31 and improve the efficiency of contactless power supply.

[0050] The substrate 33 is disposed on the opposite side of the first upper shield case 34a to the first coil portion 31. A connector 35 is mounted on the substrate 33. Power is supplied to the first coil portion 31 from outside the in-vehicle contactless power supply device 1 via the connector 35.

[0051] On the opposite side of the first upper shield case 34a with respect to the substrate 33, a first lower shield case 34b is arranged, which is made of a plate material with high electromagnetic wave shielding performance such as iron, similar to the first upper shield case 34a. That is, the substrate 33 is arranged between the first upper shield case 34a and the first lower shield case 34b. By sandwiching the substrate 33 between the first upper shield case 34a and the first lower shield case 34b in this manner, the charging circuit, control circuit, etc. mounted on the substrate 33 are prevented from being affected by external noise, and unwanted radiation is prevented from affecting peripheral devices (EMC countermeasures). In addition, it is also possible to dissipate heat to the first upper shield case 34a and the first lower shield case 34b via a heat dissipation member or the like attached to a heat source part of the charging circuit, control circuit, etc. mounted on the substrate 33 (heat dissipation countermeasures).

[0052] The first upper shield case 34a, the board 33, and the first lower shield case 34b, which are integrated with the first coil portion 31 and the first sheet 31a, are fastened together with screws 34c and nuts 34d. Hereinafter, the first upper shield case 34a, the board 33, the connector 35, and the first lower shield case 34b, which are integrated with the first coil portion 31 and the first sheet 31a, are referred to as the power supply circuit portion 30a.

[0053] The first upper case 36a and the first lower case 36b are made of resin or a composite of resin and metal, and are one size larger than the power supply circuit section 30a. The power supply circuit section 30a is disposed in an internal space formed by the abutment of the first upper case 36a and the first lower case 36b. The first upper case 36a is disposed so as to contact the first back surface 11c of the first placement section 10. Four first bosses 11d are disposed on the first back surface 11c, and each of the first bosses 11d is formed with a female screw. On the surface of the first upper case 36a opposite to the surface that contacts the first back surface 11c, a peripheral wall 36c into which the first lower case 36b is fitted and first cylindrical portions 36d that are fitted externally to each of the four first bosses 11d are formed. By fitting the first cylindrical portions 36d externally to the first bosses 11d, the first upper case 36a is positioned with respect to the first back surface 11c.

[0054] The first lower case 36b is positioned relative to the first upper case 36a by being fitted into a peripheral wall 36c formed in the first upper case 36a. A through hole 36e is formed in the first lower case 36b at a position corresponding to the first boss 11d. In addition, a through hole 34e is also formed in a portion corresponding to the first cylindrical portion 36d of the first lower shield case 34b when the power supply circuit section 30a is positioned relative to the first upper case 36a.

[0055] Then, the four first cylindrical parts 36d of the first upper case 36a are fitted onto the four first bosses 11d of the first back surface 11c, the through holes 34e of the first lower shield case 34b (the power supply circuit section 30a) are aligned with the first cylindrical parts 36d, and the first lower case 36b is fitted onto the peripheral wall 36c of the first upper case 36a. In this state, the screws 36f are inserted into the through holes 36e and 34e from the outside of the first lower case 36b and screwed into the female threads of the first bosses 11d. That is, the first upper case 36a, the power supply circuit section 30a, and the first lower case 36b are fastened together by the screws 36f. As a result, the first upper case 36a, the power supply circuit section 30a, and the first lower case 36b are positioned and fixed to the first back surface 11c of the first mounting section 10. At this time, one primary coil of the first coil section 31 is in contact with the first upper case 36a. The first upper case 36a may be integrally formed with the first back surface 11c, and the first lower case 36b may be fitted onto the peripheral wall 36c. The method for fixing the first upper case 36a, the power supply circuit section 30a, and the first lower case 36b to the first back surface 11c may be a method other than screw fixing, and the fixing method is not limited.

[0056] The second coil section 32 is composed of one primary coil. Hereinafter, one primary coil is also referred to as the second coil section 32. The second coil section 32 is electrically connected to the substrate 33. The second coil section 32 is an air-core annular plate-shaped coil, and a disk-shaped magnet 37 is disposed at the air-core portion. A second sheet 32a of a magnetic absorber made of a dielectric material is disposed on the surface of the second coil section 32 opposite to the second back surface 21c. The second coil section 32 and the magnet 37 are fixed to the second sheet 32a by a method such as adhesion. By providing the second sheet 32a, the magnetic field generated by the current flowing through the second coil section 32 can be controlled, thereby improving the efficiency of the non-contact power supply.

[0057] The second sheet 32a to which the second coil portion 32 and the magnet 37 are fixed is housed in a second case 39. The second sheet 32a is fixed to the inside of the second case 39 by a method such as adhesion. As a result, the second coil portion 32 and the magnet 37 are also fixed in the internal space of the second case 39.

[0058] The second case 39 is disposed on the second back surface 21c of the second placement portion 20. Four second bosses 21d are disposed on the second back surface 21c, and each of the second bosses 21d has a female thread. A second cylindrical portion 39a is formed on the surface of the second case 39 opposite to the surface that contacts the second back surface 21c, and is fitted onto each of the four second bosses 21d. By fitting the second cylindrical portion 39a onto the second boss 21d, the second case 39 is positioned relative to the second back surface 21c. The inner diameter of the second cylindrical portion 39a is not uniform, and a portion of the second cylindrical portion 39a is reduced in diameter. The head of the screw 39b that fixes the second case 39 to the second back surface 21c comes into contact with this reduced diameter portion, and the screwing does not proceed any further. As a result, the second case 39 can be fixed to the second back surface 21c of the second mounting portion 20 by screwing the four screws 39b into the female threads of the second boss 21d with the second cylindrical portion 39a of the second case 39 fitted onto the second boss 21d of the second back surface 21c so that the second case 39 is in contact with the second back surface 21c. At this time, the second coil portion 32 is in contact with or close to the second back surface 21c. Also, the central axis B of the second coil portion 32 is located at the center of the second mounting surface 21.

[0059] [How to use the in-vehicle non-contact power supply device] Next, a method of using the in-vehicle contactless power supply device 1 according to this embodiment will be described. With the in-vehicle contactless power supply device 1 installed in the center console 3 of the vehicle 2 (see FIG. 1), the user activates the in-vehicle contactless power supply device 1. Then, the first portable information terminal 7 is placed on the first placement surface 11 of the first placement section 10, and the second portable information terminal 8 is placed on the second placement surface 21 of the second placement section 20 (see FIGS. 5 and 6). As described above, the first portable information terminal 7 and the second portable information terminal 8 have different specifications. Specifically, the first portable information terminal 7 does not have a magnet disposed near the built-in secondary coil, and the second portable information terminal 8 has a magnet (not shown) disposed near the built-in secondary coil. Hereinafter, the magnet incorporated in the second portable information terminal 8 is also referred to as an incorporated magnet.

[0060] The secondary coil of second portable information terminal 8 is arranged relative to second coil section 32 so that the built-in magnet of second portable information terminal 8 is fixed at a position where power supply efficiency is high by the magnetic attraction force between magnet 37 when second portable information terminal 8 is placed on second mounting surface 21. This allows the secondary battery of second portable information terminal 8 to be charged efficiently. Hereinafter, placing second portable information terminal 8 on second mounting surface 21 and fixing it at a position where power supply efficiency is high is also referred to simply as placement or magnet alignment.

[0061] When the second portable information terminal 8 is placed on the second placement surface 21, the non-contact power supply unit 30 applies current only to the second coil unit 32. The non-contact power supply unit 30 can detect that the second portable information terminal 8 is placed on the second placement surface 21 by a known method. For example, a magnetic detection element may be disposed near the magnet 37 to detect a change in a magnetic field depending on the presence or absence of the second portable information terminal 8, thereby detecting the placement of the second portable information terminal 8. Alternatively, a small switch may be disposed so as to protrude from the second placement surface 21, and the placement of the second portable information terminal 8 may be detected by pressing the switch when the second portable information terminal 8 is placed on the second placement surface 21. Alternatively, the non-contact power supply unit 30 may be configured to detect the placement of the second portable information terminal 8 by non-contactly communicating information such as the received power from the second portable information terminal 8 to a control circuit mounted on the board 33 using load modulation.

[0062] 6, when the second portable information terminal 8 is placed on the second placement surface 21, the end of the second portable information terminal 8 on the Y1 side protrudes from the second placement surface 21. That is, when viewed along the Z direction, at least a part of the second portable information terminal 8 and a part of the first placement surface 11 overlap. Therefore, when the second portable information terminal 8 is placed on the second placement surface 21, the first portable information terminal 7 cannot be placed on the first placement surface 11.

[0063] When the first portable information terminal 7 is placed on the first mounting surface 11 of the first storage section 16, as described above, the first mounting surface 11 is inclined at the first angle θ1 toward the Z2 side with respect to the Y1 direction, so that the first portable information terminal 7 is fixed in a state of contact with the bottom wall 14.

[0064] When the first portable information terminal 7 is placed on the first placement surface 11, the non-contact power supply unit 30 supplies electricity only to the first coil portion 31. The non-contact power supply unit 30 can detect that the first portable information terminal 7 has been placed on the first placement surface 11 by a known method. For example, a small switch may be arranged to protrude from the bottom wall 14, and when the first portable information terminal 7 is placed and comes into contact with the bottom wall 14, the placement of the first portable information terminal 7 may be detected by pressing the switch.

[0065] Three primary coils of the first coil section 31 are arranged close to each other on the first back surface 11c of the first mounting section 10, and when charging the first mobile information terminal 7, the primary coil with the best power supply efficiency is selected. For example, regarding the power supply efficiency of the first mobile information terminal 7, information such as received power may be transmitted contactlessly from the first mobile information terminal 7 to a control circuit mounted on the substrate 33 using load modulation, so that the contactless power supply section 30 may select the primary coil with the best power supply efficiency and supply power. Also, placement of the first mobile information terminal 7 may be detected.

[0066] 5, when the first portable information terminal 7 is placed on the first placement surface 11, the end of the first portable information terminal 7 on the first opening 17 side protrudes from the first placement surface 11. That is, when viewed along the Z direction, at least a part of the first portable information terminal 7 and a part of the second placement surface 21 overlap. Therefore, when the first portable information terminal 7 is placed on the first placement surface 11, the second portable information terminal 8 cannot be placed on the second placement surface 21.

[0067] In this way, in the in-vehicle contactless power supply device 1 of this embodiment, only one of the first portable information terminal 7 and the second portable information terminal 8 can be placed on it, and only the placed portable information terminal can be charged. In other words, the first portable information terminal 7 and the second portable information terminal 8 cannot be placed on it at the same time to charge both terminals at the same time. Therefore, although the in-vehicle contactless power supply device 1 has two placement sections, the first placement section 10 and the second placement section 20, it is sufficient to have only one contactless power supply section 30. This allows the in-vehicle contactless power supply device 1 to be manufactured compactly and inexpensively.

[0068] Second Embodiment Next, an in-vehicle contactless power supply device 1 according to a second embodiment will be described with reference to Figs. 7 and 8. In this embodiment, the shape of the second placement portion 20 is different from that of the first embodiment. Other than that, the configuration is the same as that of the first embodiment. Therefore, in the description of this embodiment, the same reference numerals are used for the parts having the same configuration as the first embodiment, and detailed description of the same configuration is omitted.

[0069] In this embodiment, the second mounting surface 21 of the second mounting portion 20 is inclined toward the Z2 side by the second angle θ2 with respect to the Y1 direction, and the second mounting portion 20 does not have a recess 25. In this embodiment, for example, the first angle θ1 is 13 degrees, and the second angle θ2 is 6 degrees. Since the present embodiment does not have the recess 25, the in-vehicle contactless power supply device 1 can be made smaller. However, even in this embodiment, the second mounting portion 20 may have the recess 25.

[0070] Third Embodiment Next, an in-vehicle contactless power supply device 1 according to a third embodiment will be described with reference to Figs. 9 and 10. In this embodiment, the shape and arrangement of the first mounting section 10 and the second mounting section 20 are different from those of the first and second embodiments. Other than that, the configuration is the same as that of the first and second embodiments. Therefore, in the description of this embodiment, the same reference numerals are used for the parts having the same configuration as those of the first and second embodiments, and detailed description of the same configuration is omitted.

[0071] In this embodiment, the first placement portion 10 is disposed on the Y2 side of the housing H, and the second placement portion 20 is disposed on the Y1 side. The second placement surface 21 of the second placement portion 20 is adjacent to the top wall 15 of the first placement portion 10. In this embodiment, the first placement surface 11 is disposed inclined toward the Z2 side by a first angle θ1 with respect to the Y1 direction, and the second placement surface 21 is disposed inclined toward the Z2 side by a second angle θ2 with respect to the Y2 direction. In this embodiment, for example, the first angle θ1 is 20 degrees, and the second angle θ2 is 5 degrees. In addition, since the present embodiment does not have a recess 25, the in-vehicle non-contact power supply device 1 can be made smaller. However, even in this embodiment, the second placement portion 20 may have a recess 25.

[0072] In this embodiment, depending on the length of the long part 8a of the second portable information terminal 8, the first portable information terminal 7 and the second portable information terminal 8 can be placed simultaneously. However, even in this embodiment, the non-contact power supply unit 30 can only charge one of the portable information terminals. In this case, the non-contact power supply unit 30 may be configured to control the charging circuit so as to charge the portable information terminal placed first on the placement surface and not to charge the portable information terminal placed later on the placement surface. Alternatively, the non-contact power supply unit 30 may be configured to control the charging destination to be switched to the portable information terminal placed later when a portable information terminal placed on another placement surface is being charged while the portable information terminal placed earlier on the placement surface is being charged. By controlling in this way, when the first portable information terminal 7 and the second portable information terminal 8 are placed at the same time, both portable information terminals can be charged continuously. Alternatively, the charging destination of the non-contact power supply unit 30 may be switched between the first placement unit 10 and the second placement unit 20 by a switch or the like.

[0073] [Fourth embodiment] Next, an in-vehicle non-contact power supply device 1 according to a fourth embodiment will be described with reference to Figs. 11 to 14. In this embodiment, unlike the first to third embodiments, the in-vehicle non-contact power supply device 1 is disposed in the cabin of the vehicle 2, being incorporated in the dashboard 4 between the driver's seat and the passenger seat. Accordingly, the arrangement of the second placement portion 20 is different from that of the first to third embodiments. Other than that, the configuration is the same as that of the first to third embodiments. Therefore, in the description of this embodiment, the same reference numerals are used for the parts having the same configuration as those of the first to third embodiments, and detailed description of the same configuration is omitted.

[0074] In this embodiment, unlike the first to third embodiments, the second mobile information terminal 8 is placed on the second placement surface 21 with the long side 8a aligned along the X direction. That is, the placement direction of the second mobile information terminal 8 is different by 90 degrees from the first to third embodiments. Therefore, when viewed along the Z direction, the length of the second placement part 20 in the X direction is longer than the length in the Y direction. As in the first to third embodiments, the first mobile information terminal 7 is placed with the long side 7a inclined toward the Z2 side by the first angle θ1 with respect to the Y1 direction. In this embodiment, the first angle θ1 is, for example, 10 degrees. The second placement surface 21 of the second placement part 20 is parallel to the XY plane. Recesses 25 are formed on both sides of the second placement surface 21 in the X direction.

[0075] The first placement surface 11 of the first placement portion 10 and the second placement surface 21 of the second placement portion 20 in this embodiment are formed in a housing H. The housing H in this embodiment has a bottomed cylindrical shape with the Y2 side open and the bottom wall 14 formed on the Y1 side (see FIG. 13). The first storage portion 16 in which the first portable information terminal 7 is stored is formed on the Y1 side, and the second storage portion 27 is formed adjacent to the first storage portion 16 on the Y2 side. The first placement portion 10 is disposed in the first storage portion 16, and the second placement portion 20 is disposed in the second storage portion 27. The second storage portion 27 has a square cylindrical shape, the Y1 side is in contact with the first opening 17, and the Y2 side is the second opening 28. The first portable information terminal 7 is stored in the first storage portion 16 via the second opening 28 and the first opening 17, and the second portable information terminal 8 is stored in the second storage portion 27 via the second opening 28. The first placement surface 11 of the first placement portion 10 and the second placement surface 21 of the second placement portion 20 are adjacent to each other.

[0076] In this embodiment, when the first portable information terminal 7 is accommodated in the first accommodation section 16, at least the end of the first portable information terminal 7 opposite to the side in contact with the bottom wall 14 protrudes toward the second placement section 20 from the first placement surface 11. Therefore, when the first portable information terminal 7 is placed on the first placement surface 11, the second portable information terminal 8 cannot be placed on the second placement surface 21. Furthermore, when the second portable information terminal 8 is accommodated in the second accommodation section 27 and placed on the second placement surface 21, the first portable information terminal 7 can be accommodated in the first accommodation section 16, but cannot be placed on the first placement surface 11 because at least a part of the first opening 17 is blocked by the second portable information terminal 8.

[0077] Other embodiments (1) In the above first to third embodiments, the in-vehicle contactless power supply device 1 may be arranged in the opposite direction in the Y direction with respect to the center console 3. That is, the first mounting portion 10 may be arranged on the Y1 side of the housing H, the second mounting portion 20 may be arranged on the Y2 side, and the first mounting surface 11 may be arranged so as to be inclined by the first angle θ1 toward the Z2 side with respect to the Y2 direction.

[0078] (2) In the above first to third embodiments, the in-vehicle contactless power supply device 1 having the housing H is incorporated into the center console 3. However, at least a portion of the housing H may be configured to be integral with the center console 3.

[0079] (3) In each of the above embodiments, the first mounting portion 10 and the second mounting portion 20 were formed integrally with the housing H, but at least a portion of the first mounting portion 10 and the second mounting portion 20 may be configured to be assembled to the housing H that is formed separately from the housing H.

[0080] (4) In the above embodiment, the substrate 33 is a rigid substrate. However, it may be a substrate that is capable of elastic deformation, such as an FPC (Flexible Printed Circuit).

[0081] (5) In each of the above embodiments, magnet 37 is positioned in the air-core portion of second coil section 32. However, the position of magnet 37 is not important as long as a magnetic attraction force is generated between magnet 37 and the built-in magnet of second portable information terminal 8, and the secondary coil of second portable information terminal 8 is fixed in a position where power supply efficiency is high.

[0082] (6) Although not specified in the above third embodiment, the in-vehicle contactless power supply device 1 may be configured to be configured so that it is possible to visually check, by means of an LED or the like, which of the first portable information terminal 7 placed on the first placement surface 11 and the second portable information terminal 8 placed on the second placement surface 21 is being charged. Also, the LED or the like may be configured to display the charge level of the portable information terminal being charged. Also, these functions may be adopted in the first, second and fourth embodiments.

[0083] (7) In the above fourth embodiment, first opening 17 allows first portable information terminal 7 to be accommodated in first housing section 16 even when second portable information terminal 8 is placed on second mounting surface 21 of second housing section 27, but not to be placed on first mounting surface 11. However, the present invention is not limited to this. The distance between first mounting surface 11 and top wall 15 may be narrowed so that when second portable information terminal 8 is placed on second mounting surface 21, second portable information terminal 8 blocks most of first opening 17, making it impossible for first portable information terminal 7 to be accommodated in first housing section 16.

[0084] (8) In the first, second, and fourth embodiments, the second placement surface 21 may be spaced apart from the first placement surface 11 and disposed on the Y1 side or the Y2 side. [Industrial Applicability]
