Abstract
Description
[Technical field]
[0001] The present invention relates to a vehicle power receiving device that receives power from a power feeder installed on a road surface. [Background technology]
[0002] There is known a vehicle power receiving device that receives power from a power supply facility that includes a power supply body installed on a road surface. U.S. Patent Application Publication No. 2019 / 0111799 (Patent Document 1) discloses a vehicle power receiving device that includes power receivers (14a to 14c) that come into contact with power supply bodies (30a to 30b) installed on a road surface (11) to receive power. [Prior art documents] [Patent documents]
[0003] [Patent Document 1] US Patent Application Publication No. 2019 / 0111799 Summary of the Invention [Problem to be solved by the invention]
[0004] In Patent Document 1, a vehicle power receiving device mounted on a vehicle is disposed so as to protrude downward from the underside of the vehicle body. In contrast, in a non-power receiving state in which the vehicle power receiving device is not receiving power, it is conceivable to change the posture of the vehicle power receiving device so as to separate the power receiver from the power feeder so that the power receiver is less likely to come into contact with unevenness in the road surface or obstacles. In this case, if the conductive wire electrically connecting the power receiver and the device on the vehicle side has a small margin of length and therefore the flexibility of the conductive wire is not ensured, the conductive wire may have difficulty following the movement of the power receiver, which may hinder the posture change of the vehicle power receiving device. On the other hand, if the margin of length of the conductive wire is increased in order to ensure the flexibility of the conductive wire, there is a problem that the excess conductive wire hangs down to the road surface side and is likely to come into contact with the road surface.
[0005] It is therefore desirable to realize a vehicle power receiving device that can prevent the conductive wire from drooping down to the road surface and can easily make the conductive wire follow the movement of the power receiving body. [Means for solving the problem]
[0006] A vehicle power receiving device according to the present disclosure is a vehicle power receiving device that is mounted on a vehicle and receives power while the vehicle is traveling from a power supply facility including a power supply body installed on a road surface so as to extend along the road, the vehicle power receiving device including a base member attached to the vehicle, a power receiving body that receives power by contacting the power supply body, a connecting mechanism that connects the base member and the power receiving body, a drive mechanism that changes the position of the connecting mechanism between a contact position in which the power receiving body is in contact with the power supply body and a stored position in which the power receiving body is separated from the power supply body, and a conductive wire that electrically connects the power receiving body and a power receiving terminal provided on the vehicle, the connecting mechanism including a support arm that supports the power receiving body, and a power receiving terminal that connects the power receiving body and the power receiving terminal to a power receiving terminal provided on the vehicle. a connecting member connecting the support arm to the base member, the support arm being connected to the connecting member so as to be freely swingable around a swing axis and comprising a wire holding portion holding a portion of the conductive wire, the direction in which the support arm extends being defined as an extension direction, the direction along the swing axis being defined as a thickness direction, and a direction perpendicular to both the extension direction and the thickness direction being defined as a width direction, the wire holding portion being configured to restrict movement of the conductive wire in the thickness direction while allowing movement of the conductive wire at least in the extension direction, and the base member being provided with a wire placing portion on which at least a portion of the portion of the conductive wire extending toward the base member side beyond the wire holding portion is placed.
[0007] According to this configuration, since the support arm supporting the power receiver includes a wire holding portion, the conductive wire can be made to appropriately follow the movement of the support arm even when the support arm swings around the swing axis relative to the connecting member. Furthermore, according to this configuration, even if the length of the conductive wire is made sufficiently longer than the distance from the power receiver to the power receiving terminal along the support arm, etc., the surplus conductive wire can be placed on the wire placement portion. Therefore, it is possible to prevent the surplus conductive wire from hanging down and interfering with the road surface, the support arm, etc. Furthermore, according to this configuration, since it is easy to provide a slack in the length of the conductive wire, it is possible to prevent the conductive wire from interfering with the swing of the support arm. Thus, according to this configuration, it is possible to prevent the conductive wire from hanging down on the road surface side and to easily cause the conductive wire to follow the movement of the power receiver.

[0009] Hereinafter, an embodiment of a power receiving device for a vehicle will be described with reference to the drawings.
[0010] Fig. 1 is a top view of a vehicle power receiving device 10 (hereinafter referred to as power receiving device 10). Fig. 2 is a side view of the power receiving device 10. The power receiving device 10 is mounted on a vehicle 11, and receives a supply of power from a power supply facility 30 while the vehicle 11 is traveling. Here, the front-to-rear direction of the vehicle 11 is defined as a "vehicle front-to-rear direction VX", and the direction perpendicular to the vehicle front-to-rear direction VX when viewed in the up-down direction (vertical direction) is defined as a "vehicle width direction VY".
[0011] As shown in Fig. 1 and Fig. 2, the power supply equipment 30 includes a power supply body 32 installed on the road surface 20a of the road 20 so as to extend along the road 20. Here, with regard to the shape of a member, "extending along a certain direction" is not limited to a shape in which the extension direction of the member is parallel to the reference direction, with the reference direction being the reference direction, but may be a direction in which the extension direction of the whole or part of the member intersects the reference direction, and is used as a concept including a shape in which the extension direction of the whole of the member is within a predetermined range (for example, 45 degrees or less) with respect to the reference direction. In the illustrated example, the vehicle fore-and-aft direction VX and the direction in which the power supply body 32 extends along the road 20 are the same direction.
[0012] In this embodiment, the power supply facility 30 includes a power source 34 and an electric wire 36. The power supply body 32 is connected to, for example, a remote power source 34 via the electric wire 36 to receive power, and supplies power to the power receiving device 10 by contacting a power receiver 45 provided in the power receiving device 10. In the illustrated example, the plate-shaped power supply body 32 and an insulator 38 that insulates the power supply body 32 from the road 20 are installed in a groove 24 that is dug in the road surface 20a and extends along the vehicle front-rear direction VX. In addition, a contact surface 32a, which is the upper surface of the power supply body 32 that contacts the power receiver 45, and the road surface 20a are at the same height.
[0013] In this embodiment, the vehicle 11 is provided with a power supply detector 18 for detecting the power supply 32 in order to obtain the positional relationship between the vehicle 11 and the power supply 32 in the vehicle width direction VY. The power supply detector 18 may be an imaging device that captures an image capture range E1 including the road surface 20a, or may be a dedicated sensor for detecting the power supply 32. When the power supply detector 18 is an imaging device, the power supply 32 is detected from a captured image including the road surface 20a by, for example, image recognition. In the illustrated example, the power supply detector 18 is a front camera that captures an image capture range E1 including the road surface 20a in front of the vehicle in the vehicle longitudinal direction VX, but may be a rear camera that captures an image capture range including the road surface 20a behind the vehicle in the vehicle longitudinal direction VX. The vehicle 11 on which the power receiving device 10 is mounted is not particularly limited, but is, for example, an electric vehicle using a rotating electric machine as a driving source. The rotating electric machine receives power from the power receiving device 10 to rotate the wheels 16.
[0014] The vehicle 11 is provided with a power receiving terminal 69. The power supplied to the power receiving device 10 is supplied to electronic devices (for example, a driving source, a storage battery, a control device of the vehicle 11, etc.) equipped in the vehicle 11 via the power receiving terminal 69. In this embodiment, the mounting portion 41 is fixed to the body 14 of the vehicle 11. Examples of the body 14 include a monocoque body, a ladder frame body, etc.
[0015] In this embodiment, the lower surface of the power receiver 45 contacts the power feeder 32. The lower portion or the entirety of the power receiver 45 including the lower surface is made of, for example, a carbon-based material such as graphite, a metal-based material such as copper, a mixture thereof, or the like. The shape of the power receiver 45 is not particularly limited, and examples include shapes such as a block, a brush, and a wheel. The power supplied from the power feeder 32 to the power receiver 45 is sent to a power receiving terminal 69 by a conductive wire 65 described below.
[0016] As shown in FIG. 1, the power receiving device 10 includes a base member 42 that is attached to the vehicle 11. The base member 42 is attached to the underside of the vehicle 11. In this embodiment, the base member 42 is attached to the vehicle 11 via an attachment portion 41. The attachment portion 41 is a member that extends in the vehicle width direction VY. The base member 42 is a member that extends in the vehicle front-rear direction VX. Note that the base member 42 may be attached to the vehicle 11 without the attachment portion 41.
[0017] The power receiving device 10 includes a power receiving body 45 that receives power by contacting the power supply body 32. The power receiving device 10 also includes a connecting mechanism 43 that connects the base member 42 and the power receiving body 45. FIG. 3 is a side view showing a state in which the connecting mechanism 43 is in a contact position P1. FIG. 4 is a side view showing a state in which the connecting mechanism 43 is in a contracted position P3. FIG. 5 is a side view showing a state in which the connecting mechanism 43 is in a stored position P2. FIG. 6 is a top view of FIG. 5. FIG. 7 is a cross-sectional view taken along line VII-VII in FIG. 3. FIG. 8 is a cross-sectional view taken along line VIII-VIII in FIG. 4. FIG. 9 is a cross-sectional view showing a state in which the connecting mechanism 43 is overturned. FIG. 10 is a cross-sectional view taken along line XX in FIG. 5.
[0018] The connecting mechanism 43 is changed by a drive mechanism 70 described later between a contact position P1 in which the power receiver 45 is in contact with the power feeder 32 and a storage position P2 in which the power receiver 45 is separated from the power feeder 32. The connecting mechanism 43 includes a connecting member 51 that connects the base member 42 and the support arm 52. The connecting member 51 is connected to the base member 42 so as to be swingable about a roll axis A3 that extends along a direction intersecting the swing axis (a first swing axis A1a and a second swing axis A1b described later) of the contact position P1 when viewed in the up-down direction.
[0019] The connecting mechanism 43 includes a support arm 52 that supports the power receiver 45. The connecting mechanism 43 is configured so that the power receiver 45 is suspended by the support arm 52 in the contact position P1. In this embodiment, the support arm 52 is a band-shaped member with a rectangular cross section, but may be a member with another flat shape, such as an elliptical cross section. The support arm 52 may also be a hollow member. Here, the hollow member includes a member in which two or more band-shaped members are stacked with a gap therebetween. Here, the direction in which the support arm 52 extends is defined as the "extension direction D", the direction along the oscillation axis (A1a, A1b) described later is defined as the "thickness direction Y", and the direction perpendicular to both the extension direction D and the thickness direction Y is defined as the "width direction X".
[0020] In this embodiment, the support arm 52 is connected to the connecting member 51 so as to be freely swingable around the swing axis (A1a, A1b). As shown in FIG. 3, in the contact position P1, the extension direction D of the support arm 52 is inclined toward the lower side Z2 and toward the rear side in the vehicle longitudinal direction VX as it moves from the swing axis (A1a, A1b) toward the power receiver 45. In addition, in the contact position P1, the swing axis (A1a, A1b) is disposed along the vehicle width direction VY. In addition, in the contact position P1, the thickness direction Y is a direction along the vehicle width direction VY. In this embodiment, in the contact position P1, the thickness direction Y is parallel to the vehicle width direction VY. In addition, in the storage position P2, the thickness direction Y is a direction along the vertical direction Z. In the example shown in FIG. 5, in the storage position P2, the thickness direction Y is parallel to the vertical direction Z.
[0021] As shown in FIG. 3, the support arm 52 includes a plurality of arm members (53, 54). In this embodiment, the plurality of arm members form a link mechanism. In the illustrated example, the support arm 52 includes a first arm member 53 and a second arm member 54. Here, the swing axis of the first arm member 53 is defined as a first swing axis A1a, and the swing axis of the second arm member 54 is defined as a second swing axis A1b. The first swing axis A1a and the second swing axis A1b are arranged parallel to each other. In addition, the first arm member 53 and the second arm member 54 are arranged parallel to each other and spaced apart in the width direction X.
[0022] In this embodiment, the first arm member 53, the second arm member 54, and a support member 57 supporting the power receiving body 45 constitute a parallel link mechanism. A tip end 53a of the first arm member 53 remote from the first oscillation axis A1a is connected to the support member 57 supporting the power receiving body 45 so as to be swingable about a third oscillation axis A2a parallel to the first oscillation axis A1a and the second oscillation axis A1b. A tip end 54a of the second arm member 54 remote from the second oscillation axis A1b is connected to the support member 57 supporting the power receiving body 45 so as to be swingable about a fourth oscillation axis A2b parallel to the first oscillation axis A1a and the second oscillation axis A1b.
[0023] The parallel link mechanism is, for example, a four-joint link mechanism in which the opposing links are equal in length. In the illustrated example, the parallel link mechanism is made up of a connecting member 51, a support member 57, a first arm member 53, and a second arm member 54. In addition, the distance between the first oscillation axis A1a and the second oscillation axis A1b is equal to the distance between the third oscillation axis A2a and the fourth oscillation axis A2b.
[0024] The connecting mechanism 43 is configured to roll the support arm 52 about a roll axis A3 that is aligned in a direction intersecting the swing axis (A1a, A1b) of the contact position P1 when viewed in the up-down direction so that the thickness direction Y of the support arm 52 is aligned along the horizontal direction in the contact position P1 and aligned along the up-down direction Z in the storage position P2. The thickness direction Y in the contact position P1 is not limited to a direction parallel to the horizontal direction, and may be inclined relative to the parallel direction. The thickness direction Y in the storage position P2 is not limited to a direction parallel to the up-down direction Z, and may be inclined relative to the parallel direction.
[0025] In this embodiment, the axial direction of the rollover axis A3 is along the vehicle longitudinal direction VX, but may be along the vehicle width direction VY. In this embodiment, the axial direction of the rollover axis A3 is horizontal, but may be inclined relative to the horizontal direction. In this embodiment, the axial direction of the rollover axis A3 is perpendicular to the swing axes (A1a, A1b) when viewed in the up-down direction, but it does not have to be perpendicular as long as it intersects with the swing axes (A1a, A1b). The rollover of the support arm 52 may be the rollover of the connecting member 51 relative to the base member 42, or may be the bending and swinging of the support arm 52 around the rollover axis A3.
[0026] The support arm 52 is formed such that the dimension L1 in the width direction X is larger than the dimension L2 in the thickness direction Y. In this embodiment, the dimension L1 in the width direction X of the support arm 52 is the dimension in the width direction X of the entire support arm 52 connected to one support member 57 or one power receiver 45 that supports the power receiver 45. The dimension L2 in the thickness direction Y of the support arm 52 is the dimension in the thickness direction Y of the entire support arm 52 connected to one support member 57 or one power receiver 45 that supports the power receiver 45. In addition, for example, when a member that rolls around the roll axis A3 integrally with the first arm member 53 or the second arm member 54 is attached to the first arm member 53 or the second arm member 54, the dimension in the width direction X of the entire support arm 52 including the member is the dimension L1 in the width direction X, and the dimension in the thickness direction Y of the entire support arm 52 including the member is the dimension L2 in the thickness direction Y.
[0027] Here, the support arm 52 includes a plurality of arm members, and the dimension L1 in the width direction X of the support arm 52 or the dimension L2 in the thickness direction Y of the support arm 52 may differ between the contact position P1 and the storage position P2. In this embodiment, the support arm 52 is formed such that the dimension L1 in the width direction X is larger than the dimension L2 in the thickness direction Y at least in the storage position P2. Also, in this embodiment, the dimension L1 in the width direction X of the support arm 52 is formed larger than the dimension L3 in the thickness direction Y of the connecting member 51. Also, the dimension L1 in the width direction X of the support arm 52 is formed such that the dimension L1 in the width direction X of the support arm 52 is larger than the dimension L3 in the thickness direction Y of the connecting member 51 at least in the storage position P2.
[0028] The power receiving device 10 includes a drive mechanism 70 that changes the position of the connecting mechanism 43 between a contact position P1 in which the power receiving body 45 is in contact with the power supply body 32 and a storage position P2 in which the power receiving body 45 is separated from the power supply body 32. The drive mechanism 70 is configured to be capable of a rolling operation that swings the connecting member 51 and the support arm 52 about the rolling axis A3 so that in the contact position P1, the power receiving body 45 is suspended by the support arm 52 and the swing axis (A1a, A1b) of the support arm 52 is in a first position Pb1 along the horizontal direction, and in the storage position P2, the swing axis (A1a, A1b) of the support arm 52 is in a second position Pb2 along the vertical direction Z.
[0029] In this embodiment, when the drive mechanism 70 changes the position of the connecting mechanism 43 from the storage position P2 to the contact position P1, it swings the connecting member 51 around the roll axis A3 to bring the thickness direction Y of the support arm 52 into a position along the horizontal direction, and then swings the support arm 52 around the swing axis (A1a, A1b) to lower the power receiving body 45.
[0030] In this embodiment, when changing the position of the connecting mechanism 43 from the contact position P1 to the storage position P2, the drive mechanism 70 swings the support arm 52 about the swing axis A1 to raise the power receiver 45, and then swings the connecting mechanism 43 about the roll axis A3 to bring the thickness direction Y of the support arm 52 into the vertical direction Z. Figures 4 and 8 show the connecting mechanism 43 in the contracted position P3, that is, after the support arm 52 has been swung about the swing axis A1 to raise the power receiver 45, the thickness direction Y of the support arm 52 is in the horizontal direction.
[0031] In this embodiment, the drive mechanism 70 is configured to allow the support arm 52 to swing relative to the connecting member 51 around the swing axis (A1a, A1b) in the contact position P1, while being capable of swing regulation that regulates the swing of the connecting member 51 relative to the base member 42 around the roll axis A3 in both the contact position P1 and the storage position P2.
[0032] The drive mechanism 70 includes a drive device 71 (see FIG. 2) and a transmission mechanism 74 that transmits the drive force of the drive device 71 to the connecting member 51 and the support arm 52. The transmission mechanism 74 executes a lowering operation to swing the support arm 52 about the swing axis (A1a, A1b) by the drive force of the drive device 71, thereby lowering the power receiver 45. The transmission mechanism 74 also executes a lifting operation to swing the support arm 52 about the swing axis (A1a, A1b) by the drive force of the drive device 71, thereby lifting the power receiver 45. Examples of the drive device 71 include a rotating electric machine, a pneumatic pump, a hydraulic pump, and a solenoid actuator.
[0033] In this embodiment, the transmission mechanism 74 executes a rolling operation to swing the connecting member 51 and the support arm 52 about the roll axis A3 from the second position Pb2 to the first position Pb1 by the driving force of the drive device 71. Also, the transmission mechanism 74 executes a rolling operation to swing the connecting member 51 and the support arm 52 about the roll axis A3 from the first position Pb1 to the second position Pb2 by the driving force of the drive device 71.
[0034] In this embodiment, the transmission mechanism 74 is configured to sequentially execute, by operation of the drive device 71, an unlocking operation that releases the restriction on the swinging of the connecting member 51 about the roll axis A3 from the storage position P2, a rolling operation that swings the connecting member 51 and the support arm 52 about the roll axis A3 from the second position Pb2 to the first position Pb1 after completion of the unlocking operation, a locking operation that restricts the swinging of the connecting member 51 about the roll axis A3 after completion of the rolling operation, and a lowering operation that swings the support arm 52 about the swing axis (A1a, A1b) to lower the power receiving body 45 after completion of the locking operation.
[0035] In this embodiment, the transmission mechanism 74 is configured to sequentially execute the following operations by the operation of the drive device 71: an ascent operation in which the support arm 52 is swung around the swing axis (A1a, A1b) from the contact position P1 to raise the power receiving body 45; an unlocking operation in which, after the ascent operation is completed, the restriction on the swing of the connecting member 51 around the roll axis A3; a rollover operation in which, after the unlocking operation is completed, the connecting member 51 and the support arm 52 are swung around the roll axis A3 from the first position Pb1 to the second position Pb2; and a locking operation in which, after the rollover operation is completed, the swing of the connecting member 51 around the roll axis A3 is restricted.
[0036] In this embodiment, the transmission mechanism 74 includes a transmission member 75 that operates in a specific transmission direction B by the driving force of the drive device 71. In the example shown in Fig. 3, the transmission mechanism 74 includes a pulley 76. Examples of the transmission member 75 include a wire, a cable, a chain, and a gear.
[0037] In the illustrated example, the transmission mechanism 74 is disposed so as to pass through the inside of a cylindrical member 79 fixed to the base member 42 or the connecting member 51. One end of the transmission member 75 is fixed to the vehicle body 14, the mounting portion 41, or the base member 42, and the other end is pulled by the driving device 71, so that the support arm 52 swings around the swing axis (A1a, A1b) and the power receiver 45 rises. The connecting mechanism 43 also includes a first elastic member 55 (see FIG. 3) that biases the support arm 52 against the connecting member 51. The first elastic member 55 biases the support arm 52 against the connecting member 51 in a direction in which the power receiver 45 descends and contacts the power feeder 32. Examples of the first elastic member 55 include a coil spring, a torsion coil spring, and a leaf spring.
[0038] The power receiving device 10 includes a conductive wire 65 that electrically connects the power receiver 45 and a power receiving terminal 69 (see FIG. 2) provided on the vehicle 11. In this embodiment, the conductive wire 65 is passed through the inside of the support arm 52. In addition, the conductive wire 65 is passed through the inside of the connecting member 51.
[0039] As shown in FIG. 3 and FIG. 7, the support arm 52 includes a first wire holding portion 62 that holds a part of the conductive wire 65. The first wire holding portion 62 is configured to restrict movement of the conductive wire 65 in the thickness direction Y. The first wire holding portion 62 is configured to allow movement of the conductive wire 65 at least in the extension direction D. This allows sagging of the conductive wire 65 in the support arm 52. In this embodiment, the support arm 52 includes a hollow arm member (in the illustrated example, the first arm member 53), and a part of the conductive wire 65 is held inside the arm member. The first wire holding portion 62 is an inner wall surface of the arm member. The first wire holding portion 62 is configured so that the conductive wire 65 passes above the third oscillation axis A2a in the contact posture P1. The first wire holding portion 62 is configured so that the conductive wire 65 passes above the first oscillation axis A1a in the contact posture P1. The first wire holding portion 62 corresponds to the "wire holding portion."
[0040] In this embodiment, the first wire holding portion 62 is configured to allow movement of the conductive wire 65 in the width direction X. Note that the first wire holding portion 62 may be configured to restrict movement of the conductive wire 65 on a side closer to the road surface 20a in the width direction X. Also, the first wire holding portion 62 may be configured to restrict movement of the conductive wire 65 on both sides in the width direction X.
[0041] The first wire holding portion 62 is configured to allow movement of the conductive wire 65 in the extension direction D or in at least one direction other than the thickness direction Y, for example, within a range of 3 times or less, 5 times or less, or 10 times or less of the diameter of the conductive wire 65.
[0042] Preferably, the first wire holding portion 62 is configured to restrict movement of the conductive wire 65 in the thickness direction Y by more than three times the diameter of the conductive wire 65. More preferably, the first wire holding portion 62 is configured to restrict movement of the conductive wire 65 in the thickness direction Y by more than two times the diameter of the conductive wire 65. Even more preferably, the first wire holding portion 62 is configured to restrict movement of the conductive wire 65 in the thickness direction Y by more than 1.5 times the diameter of the conductive wire 65.
[0043] The connecting member 51 includes a second wire holding portion 63 that holds a part of the conductive wire 65. The second wire holding portion 63 is configured to restrict movement of the conductive wire 65 in the thickness direction Y. The second wire holding portion 63 is configured to allow movement of the conductive wire 65 in at least one direction other than the thickness direction Y. In this manner, slack of the conductive wire 65 in the connecting member 51 is allowed. In the illustrated example, the second wire holding portion 63 is configured to allow movement of the conductive wire 65 in all directions perpendicular to the thickness direction Y. In this embodiment, the connecting member 51 is a hollow member, and a part of the conductive wire 65 is held inside the connecting member 51. The second wire holding portion 63 is an inner wall surface of the connecting member 51. The second wire holding portion 63 is configured so that the conductive wire 65 passes above the first oscillation axis A1a in the contact posture P1.
[0044] In the example shown in FIG. 3, in the contact posture P1, the second wire holding portion 63 is configured to allow the conductive wire 65 to move in the vertical direction Z.

The wire placement portion 64 is configured to place at least a part of the portion of the conductive wire 65 extending toward the base member 42 side beyond the second wire holding portion 63.

Moreover, the wire placing portion 64 is configured to allow movement of the conductive wire 65 in at least one direction other than the vertical direction Z. Moreover, the wire placing portion 64 is configured to allow movement of the conductive wire 65 in the direction in which the conductive wire 65 extends. Preferably, the wire placing portion 64 is configured to allow movement of the conductive wire 65 in one direction or all directions along the horizontal direction.
[0053] Preferably, the wire placing portion 64 is configured to restrict movement of the conductive wire 65 in a direction along the vertical direction Z that is three times or more the diameter of the conductive wire 65. More preferably, the wire placing portion 64 is configured to restrict movement of the conductive wire 65 in a direction along the vertical direction Z that is two times or more the diameter of the conductive wire 65. Even more preferably, the wire placing portion 64 is configured to restrict movement of the conductive wire 65 in a direction along the vertical direction Z that is 1.5 times or more the diameter of the conductive wire 65.
[0054] Preferably, the wire support portion 64 is configured to allow movement of the conductive wire 65 in a direction perpendicular to the extension direction of the conductive wire 65 and the vertical direction Z (in the illustrated example, the vehicle width direction VY) within a range of 3 times or less, or 5 times or less, or 10 times or less of the diameter of the conductive wire 65.
[0055] In this embodiment, the wire placing portion 64 is configured to place a portion of the conductive wire 65 that has moved from the outside to the inside of the wire placing portion 64 when the connecting mechanism 43 is changed in position from the contact position P1 to the storage position P2.

[0056] Fig. 11 is a side view of the cam mechanism 80 when the connecting mechanism 43 is in the contact position P1. Fig. 12 is a cross-sectional view of the cam mechanism 80 when the connecting mechanism 43 is in the contact position P1. Fig. 13 is a cross-sectional view of the cam mechanism 80 when the connecting mechanism 43 is in the storage position P2. The transmission mechanism 74 is equipped with a cam mechanism 80 that converts the movement of the transmission member 75 into the movement of the connecting member 51 and the support arm 52. Examples of the cam mechanism 80 include a three-dimensional cam mechanism such as a cylindrical cam, and a planar cam mechanism such as a plate-shaped cam.
[0057] In this embodiment, the cam mechanism 80 includes a first cam member 85 and a second cam member 86. The first cam member 85 is connected to the connecting member 51 so as not to be able to swing around the rollover axis A3. The first cam member 85 is connected to the connecting member 51 so as to be able to move in the axial direction of the rollover axis A3. The first cam member 85 is connected to the second cam member 86 so as to be able to swing around the rollover axis A3. The second cam member 86 is fixed to the base member 42. In the example shown in FIG. 13, a groove 88a extending in the axial direction of the rollover axis A3 is formed on the inner peripheral surface of the first cam member 85, and a protrusion 88b that fits into the groove 88a is formed on the outer peripheral surface of the connecting member 51. As a result, the first cam member 85 is connected to the connecting member 51 so as not to be able to swing around the rollover axis A3 and to be able to move in the axial direction of the rollover axis A3.
[0058] In this embodiment, the cam mechanism 80 includes a second elastic member 87 that stores the driving force of the drive unit 71. The second elastic member 87 biases the first cam member 85 against the second cam member 86. Examples of the second elastic member 87 include a coil spring, a torsion coil spring, and a leaf spring. Note that development views of the first cam member 85 are shown in Figs. 12 and 13.
[0059] The transmission member 75 is configured to operate the cam mechanism 80 by moving in a predetermined first operating region toward a transmission direction first side B1, which is one side of the transmission direction B. The transmission member 75 is also configured to swing the support arm 52 about the swing axis (A1a, A1b) to lower the power receiver 45 by moving in a second operating region toward the transmission direction first side B1, which is closer to the transmission direction first side B1 than the first operating region.
[0060] The transmission member 75 is configured to operate the cam mechanism 80 by moving in a predetermined first operating region toward the second side B2 in the transmission direction, which is the other side of the transmission direction B. The transmission member 75 is also configured to swing the support arm 52 about the swing axis (A1a, A1b) to lift the power receiver 45 by moving in a second operating region toward the second side B2 in the transmission direction, which is closer to the first side B1 in the transmission direction than the first operating region.
[0061] In this embodiment, the cam mechanism 80 is operated by engaging the cam contact portion 75a fixed to the transmission member 75 with the first cam member 85. The first operating region is a region in which the cam contact portion 75a is engaged with the first cam member 85. The second operating region is a region in which the cam contact portion 75a is not engaged with the first cam member 85.
[0062] Here, one side of the cam operation direction in the cam mechanism 80 is referred to as the cam operation direction first side C1, and the other side of the cam operation direction is referred to as the cam operation direction second side C2. Examples of the cam operation direction include the rotational movement of a cylindrical cam, the rotational movement of a plate-shaped cam, and the linear movement of a plate-shaped cam, etc. In the illustrated example, the cam operation direction is a swinging movement of the first cam member 85 around the rollover axis A3 relative to the second cam member 86.
[0063] The cam mechanism 80 is configured to operate to the cam operating direction first side C1 in response to the operation of the transmission member 75 in the first operating region to the transmission direction first side B1. The cam mechanism 80 is also configured to operate to the cam operating direction second side C2 in response to the operation of the transmission member 75 in the first operating region to the transmission direction second side B2.
[0064] The cam mechanism 80 includes a first cam region 81, a second cam region 82, and a third cam region 83, each having a different cam profile. The second cam region 82 is a region on the first side C1 in the cam operation direction relative to the first cam region 81. The third cam region 83 is a region on the first side C1 in the cam operation direction relative to the second cam region 82.
[0065] The first cam region 81 is configured to restrict the swing of the connecting member 51 around the roll axis A3 to maintain the connecting member 51 in the second position Pb2. The second cam region 82 is configured to swing the connecting member 51 around the roll axis A3 from the second position Pb2 to the first position Pb1 in response to the movement of the cam mechanism 80 toward the first side C1 in the cam operation direction. The second cam region 82 is configured to swing the connecting member 51 around the roll axis A3 from the first position Pb1 to the second position Pb2 in response to the movement of the cam mechanism 80 toward the second side C2 in the cam operation direction. The third cam region 83 is configured to restrict the swing of the connecting member 51 around the roll axis A3 to maintain the connecting member 51 in the first position Pb1.
[0066] 1 and 2, the power receiving device 10 includes a plurality of power receivers 45 (three in the illustrated example). The power receiving device 10 also includes a plurality of connecting mechanisms 43 (three in the illustrated example). In this embodiment, the plurality of power receivers 45 are arranged separately in the vehicle longitudinal direction VX. Note that the plurality of power receivers 45 may also be arranged separately in the vehicle longitudinal direction VX and the vehicle width direction VY.
[0067] The drive mechanism 70 is configured to change the positions of the multiple connecting mechanisms 43 between a contact position P1 and a storage position P2 by one drive device 71. In this embodiment, the drive device 71 and the transmission member 75 are provided in common to the multiple connecting mechanisms 43, and the cam mechanism 80 is provided corresponding to each of the multiple connecting mechanisms 43. Preferably, one drive device 71 is one drive source.
[0068] The power receiving device 10 includes a moving mechanism 90 that moves the connecting mechanism 43 and the power receiver 45 in the vehicle width direction VY relative to the vehicle 11. In this embodiment, the moving mechanism 90 moves the base member 42 in the vehicle width direction VY relative to the mounting portion 41. Note that the moving mechanism 90 may move the connecting mechanism 43 and the power receiver 45 in the vehicle width direction VY and the vehicle front-rear direction VX, that is, may move obliquely with respect to the vehicle width direction VY. Examples of the moving mechanism 90 include a mechanism using a worm gear, a belt, or the like.
[0069] In this embodiment, when the coupling mechanism 43 is in the storage position P2, the coupling mechanism 43 and the power receiver 45 are entirely disposed within a range overlapping with the vehicle body 14 in the vehicle width direction VY as viewed in the vertical direction. When the coupling mechanism 43 is in the storage position P2, the coupling mechanism 43 and the power receiver 45 are entirely disposed within a range overlapping with the vehicle body 14 in the vehicle front-rear direction VX as viewed in the vertical direction. When the coupling mechanism 43 is in the storage position P2, the lower end of the coupling mechanism 43 may be configured to be located on the upper side Z1 than the lower end of the vehicle body 14. When the coupling mechanism 43 is in the storage position P2, the lower end of the power receiver 45 may be configured to be located on the upper side Z1 than the lower end of the vehicle body 14. When the coupling mechanism 43 is in the storage position P2, the coupling mechanism 43 and the power receiver 45 are configured to be located, for example, between the storage battery of the vehicle 11 and the road surface 20a.
[0070] In this embodiment, one end of the conductive wire 65 is fixed to the power receiver 45, and the other end is fixed to the power receiving terminal 69. The power receiving device 10 is configured to allow movement of the conductive wire 65 in the direction in which the conductive wire 65 extends between the power receiver 45 and the power receiving terminal 69. This makes it easier to allow both bending and twisting of the conductive wire 65 when the connecting mechanism 43 changes position between the contact position P1 and the storage position P2.
[0071] As described above, the power receiving device 10 of the present embodiment includes the base member 42 attached to the vehicle 11, the power receiving body 45 that receives power by contacting the power feeder 32, the connecting mechanism 43 that connects the base member 42 and the power receiving body 45, the drive mechanism 70 that changes the position of the connecting mechanism 43 between a contact position P1 in which the power receiving body 45 is in contact with the power feeder 32 and a storage position P2 in which the power receiving body 45 is separated from the power feeder 32, and the conductive wire 65 that electrically connects the power receiving body 45 and a power receiving terminal 69 provided on the vehicle 11. The connecting mechanism 43 includes a support arm 52 that supports the power receiving body 45, and a connecting member 51 that connects the base member 42 and the support arm 52. The support arm 52 is configured to swing freely around a swing axis (a first swing axis A1a and a second swing axis A1b). The support arm 52 is currently connected to the connecting member 51, and the support arm 52 has a wire holding portion (first wire holding portion 62) that holds a part of the conductive wire 65, and the direction in which the support arm 52 extends is defined as an extension direction D, the direction along the oscillation axis (A1a, A1b) is defined as a thickness direction Y, and the direction perpendicular to both the extension direction D and the thickness direction Y is defined as a width direction X. The wire holding portion (first wire holding portion 62) is configured to restrict movement of the conductive wire 65 in the thickness direction Y and to allow movement of the conductive wire 65 at least in the extension direction D, and the base member 42 has a wire placing portion 64 on which at least a part of a portion of the conductive wire 65 that extends toward the base member 42 side beyond the wire holding portion (first wire holding portion 62) is placed.
[0072] According to the above-described power receiving device 10, since the support arm 52 supporting the power receiver 45 includes a wire holding portion (first wire holding portion 62), the conductive wire 65 can be made to appropriately follow the movement of the support arm 52 even when the support arm 52 swings around the swing axis (A1a, A1b) relative to the connecting member 51. Furthermore, according to this configuration, even if the length of the conductive wire 65 is made sufficiently longer than the distance from the power receiver 45 to the power receiving terminal 69 along the support arm 52, etc., the surplus conductive wire 65 can be placed on the wire placement portion 64. Therefore, it is possible to prevent the surplus conductive wire 65 from sagging on the lower side Z2 and interfering with the road surface 20a, the support arm 52, etc. Furthermore, according to this configuration, since it is easy to provide a slack in the length of the conductive wire 65, it is possible to prevent the conductive wire 65 from interfering with the swing of the support arm 52. Therefore, it is easy to make the conductive wire 65 appropriately follow the movement of the power receiver 45.
[0073] In the power receiving device 10 of this embodiment, the wire placement portion 64 is configured to restrict movement of the conductive wire 65 in the vertical direction Z and to allow movement of the conductive wire 65 in at least one other direction.
[0074] According to the power receiving device 10 described above, the area in the vertical direction Z occupied by the conductive wire 65 placed on the wire placement portion 64 can be kept small. Therefore, the dimension of the power receiving device 10 in the vertical direction Z can be easily kept small.
[0075] In the power receiving device 10 of this embodiment, the connecting member 51 is connected to the base member 42 so as to be freely swingable around a roll axis A3 that extends along a direction intersecting the swing axis (A1a, A1b) of the contact posture P1 when viewed in the up-down direction, and is provided with a second wire holding portion 63 that holds a part of the conductive wire 65. The second wire holding portion 63 is configured to restrict movement of the conductive wire 65 in the thickness direction Y while allowing movement of the conductive wire 65 in at least one other direction, and the wire mounting portion 64 is configured so that at least a part of the portion of the conductive wire 65 that extends toward the base member 42 side beyond the second wire holding portion 63 is mounted on the wire mounting portion 64.
[0076] According to the above-mentioned power receiving device 10, since both the support arm 52 and the connecting member 51 are provided with the wire holding portions (91, 92), the conductive wire 65 can be prevented from interfering with the movement of the support arm 52 and the connecting member 51 even when the support arm 52 swings relative to the connecting member 51 around the swing axis (A1a, A1b) and the connecting member 51 swings relative to the base member 42 around the roll axis A3.
[0077] In the power receiving device 10 of this embodiment, the wire mounting portion 64 is configured to fit within the arrangement area of the connecting member 51 and the support arm 52 in the vertical direction Z when the connecting member 51 and the support arm 52 swing around the roll axis A3 and the thickness direction Y of the support arm 52 is in a position along the vertical direction Z.
[0078] According to the above-described power receiving device 10, when the connecting member 51 and the support arm 52 swing around the roll axis A3 and the thickness direction Y of the support arm 52 is aligned along the vertical direction Z, the wire placement portion 64 does not protrude in the vertical direction Z relative to the connecting member 51 and the support arm 52. Therefore, it is easy to keep the dimension of the power receiving device 10 in the vertical direction Z small in such a position.
[0079] Other embodiments Next, other embodiments of the power receiving device 10 will be described.
[0080] (1) In the above embodiment, a configuration has been described in which the connecting member 51 is connected to the base member 42 so as to be freely swingable about the rollover axis A3. However, the present invention is not limited to such an example, and for example, the connecting member 51 may be configured integrally with the base member 42, or may be a separate member that is fixed integrally with the base member 42. Also, the storage position P2 does not have to be a position in which the thickness direction Y of the support arm 52 is aligned with the up-down direction Z. For example, the contracted position P3 may be a storage position P2 in which the power receiver 45 is separated from the power supplier 32.
[0081] (2) In the above embodiment, a configuration has been described as an example in which the wire placing portion 64 restricts movement of the conductive wire 65 in the vertical direction Z while allowing movement of the conductive wire 65 in other directions. However, the present invention is not limited to such an example, and may be configured, for example, in such a manner that the wire placing portion 64 does not restrict movement of the conductive wire 65 to the upper side Z1. Also, for example, a portion of each of the multiple conductive wires 65 may be fixed to the wire placing portion 64.
[0082] (3) In the above embodiment, the second wire holding portion 63 is configured to restrict movement of the conductive wire 65 in the thickness direction Y while allowing movement of the conductive wire 65 in other directions. However, without being limited to such an example, for example, the second wire holding portion 63 may be configured to allow movement of the conductive wire 65 in the thickness direction Y while restricting movement of the conductive wire 65 in the width direction X. Furthermore, the connecting member 51 does not need to be equipped with the second wire holding portion 63.
[0083] (4) In the above embodiment, an example has been described in which the wire mounting portion 64 fits within the arrangement area of the connecting member 51 and the support arm 52 in the up-down direction Z when the connecting member 51 and the support arm 52 are in the stored posture P2. However, the present invention is not limited to such an example, and for example, the dimension L6 of the wire mounting portion 64 in the up-down direction Z may be greater than the dimension L3 or the dimension L2.
[0084] (5) In the above embodiment, a configuration has been described as an example in which the conductive wire 65 is passed through the connecting member 51 and the first arm member 53. However, without being limited to such an example, for example, the first wire holding portion 62 may be provided on the outer surface of the first arm member 53, and the conductive wire 65 may be located outside the first arm member 53. In addition, for example, the second wire holding portion 63 may be provided on the outer surface of the connecting member 51, and the conductive wire 65 may be located outside the connecting member 51.
[0085] (6) In the above embodiment, a configuration has been described in which one driving device 71 swings the multiple support arms 52 around the swing axis (A1a, A1b) and swings the multiple connecting members 51 and the multiple support arms 52 around the roll axis A3. However, the present invention is not limited to such an example, and may be configured in such a way that multiple driving devices 71 swing the multiple support arms 52 around the swing axis (A1a, A1b). Also, for example, the multiple driving devices 71 may swing the multiple connecting members 51 and the multiple support arms 52 around the roll axis A3. Also, the driving device 71 that swings the support arm 52 around the swing axis (A1a, A1b) and the driving device 71 that swings the multiple connecting members 51 and the multiple support arms 52 around the roll axis A3 may be different driving devices 71.
[0086] (7) In the above embodiment, a configuration has been described as an example in which, in the contact posture P1, the swing axis (A1a, A1b) is disposed along the vehicle width direction VY, and the extension direction D of the support arm 52 is inclined toward the lower side Z2 and the rear side in the vehicle longitudinal direction VX as it moves from the swing axis (A1a, A1b) toward the power receiver 45. However, without being limited to such an example, for example, in the contact posture P1, the swing axis (A1a, A1b) may be disposed along the vehicle longitudinal direction VX, and the extension direction D of the support arm 52 may be inclined toward the lower side Z2 and the rear side in the vehicle longitudinal direction VX as it moves from the swing axis (A1a, A1b) toward the power receiver 45. Furthermore, the extending direction D of the support arm 52 does not have to be inclined downward Z2 and rearward in the vehicle front-rear direction VX as it moves from the swing axis (A1a, A1b) toward the power receiver 45 side.
[0087] (8) In the above embodiment, the support arm 52 includes the first arm member 53 and the second arm member 54. However, the present invention is not limited to such an example, and the support arm 52 may be, for example, a single longitudinal member. Furthermore, the first oscillation axis A1a and the second oscillation axis A1b may be the same axis. Furthermore, the third oscillation axis A2a and the fourth oscillation axis A2b may be the same axis.
[0088] (9) In the above embodiment, a configuration has been described as an example in which the tip end 53a of the first arm member 53 and the tip end 54a of the second arm member 54 are each connected to the support member 57 so as to be able to swing freely. However, without being limited to such an example, for example, the tip end 53a of the first arm member 53 and the tip end 54a of the second arm member 54 may each be connected to the power receiver 45 so as to be able to swing freely around axes (third oscillation axis A2a and fourth oscillation axis A2b) parallel to the first oscillation axis A1a and the second oscillation axis A1b, and the first arm member 53, the second arm member 54, and the power receiver 45 may form a parallel link mechanism.
[0089] (10) In the above embodiment, a configuration has been described in which the thickness direction Y is a direction along the vehicle width direction VY in the contact posture P1 and a direction along the up-down direction Z in the storage posture P2. However, the present invention is not limited to such an example, and may be, for example, a configuration in which the thickness direction Y is a direction along the vehicle front-rear direction VX in the contact posture P1 and a direction along the up-down direction Z in the storage posture P2.
[0090] (11) The configurations disclosed in the above-described embodiments can be applied in combination with configurations disclosed in other embodiments, as long as no contradiction occurs. As for other configurations, the embodiments disclosed in this specification are merely examples in all respects. Therefore, various modifications can be made as appropriate within the scope of the present disclosure. [Explanation of symbols]
