[0029] Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, although the embodiments described below are subject to various technically preferable limitations for carrying out the present invention, the technical scope of the present invention is not limited to the following embodiments and illustrated examples.
[0030] The following embodiments of the invention will be described by way of example with reference to a power supply system 1 for a vehicle seat 10 and a vehicle 100 on which the vehicle seat 10 is mounted. This power supply system 1 includes a vehicle seat 10 equipped with a wireless power receiving device 16 and a wired power receiving device 17, a wired power transmitting device 120 provided in a vehicle 100 capable of mounting the vehicle seat 10, and a wireless power transmitting device 90 installed outside (outdoors) of the vehicle 100.
[0031] FIG. 1 is a perspective view showing an image of use of a power supply system 1 including a vehicle seat 10 and a vehicle 100, FIG. 2 is a schematic configuration diagram of a vehicle 100 equipped with the vehicle seat 10 and the power supply system 1, FIG. 3 is a block diagram showing the configuration of the vehicle seat 10, and FIG. 4 is a block diagram showing the configuration of the vehicle 100 excluding the vehicle seat 10.
[0032] 1 and 2, a vehicle seat 10 mounted on a vehicle 100 as an interior seat has wheels 11 for allowing a person to move while seated. The vehicle 100 has a hatch 100a and a slope 100b, and the vehicle seat 10 can be moved outside the vehicle by opening the hatch 100a and pulling out the slope 100b. The vehicle seat 10 can receive power via wired power supply from a power transmission connector 121 (see Figure 8) of a wired power transmission device 120 installed inside the vehicle 100, and can also receive power via wireless power supply from a wireless power transmission device 90 installed outdoors.
[0033] Examples of a method (wireless power supply method) for supplying power wirelessly (i.e., contactlessly) from the wireless power transmitting device 90 to the vehicle seat 10 include an electromagnetic induction method, a magnetic field resonance method, an electric field coupling method, and a radio wave reception method. The electromagnetic induction method is a method in which an induced magnetic flux is generated between the power transmitting coil and the power receiving coil by passing a current through the power transmitting coil while the two coils are close to each other, and an induced electromotive force is generated in the power receiving coil using this induced magnetic flux as a medium. The magnetic resonance method is a method of supplying power by embedding a coil and a capacitor on the power transmitting side and the power receiving side and causing magnetic resonance between the respective resonators. The electric field coupling method is a method in which electrodes are installed on both the power transmitting and receiving sides, and power is supplied using the electric field that is generated when the electrodes are close to each other. The radio wave reception method is a method of supplying power by converting electric current into electromagnetic waves on the power transmitting side and sending them to the power receiving side. In this radio wave reception method, the power receiving side receives electromagnetic waves from an antenna, converts them into direct current through a rectifier circuit, and uses them as power. In this embodiment, an electromagnetic induction method is adopted as the wireless power feeding method.
[0034] Vehicle 100 is a so-called self-driving vehicle that can travel autonomously to a destination without being operated by a passenger. When a passenger of vehicle 100 gets into the vehicle while remaining seated in vehicle seat 10, vehicle seat 10 is fixed and held at a predetermined location inside the vehicle to become a seat for vehicle 100, and the passenger can travel to the destination by self-driving.
[0035] [Vehicle seat: whole] 5 is an exploded perspective view showing the schematic configuration of a vehicle seat 10. As shown in the figure, the vehicle seat 10 includes a carriage 12 having wheels 11 and a seat portion 13 mounted on the upper side of the carriage 12. As shown in FIG. 3 , the vehicle seat 10 also includes a traction motor 181 as an electrical component that drives the wheels 11, a wireless power receiving device 16 that can receive power from the outside via wireless power supply, a wired power receiving device 17 that can receive power from the outside via wired power supply, a shutter mechanism 30 of the power receiving coil 161 and the power receiving connector 171 described below, an operating device 182 for the vehicle seat 10, a communication device 183 that performs wireless communication with the outside, a lock sensor 187 as a lock detection unit that detects a state in which the vehicle seat 10 is locked within the vehicle 100, a power source 184 as an electrical component that serves as a power source for each part of the vehicle seat 10, a power supply circuit 185 that adjusts the power from the power source 184 and supplies it to each part, and a control unit 186 that controls and processes each part of the vehicle seat 10.
[0036] [Vehicle seat: seat section] The seat portion 13 includes a seat cushion 131 that supports the buttocks and thighs of a person, a seat back 132 whose lower end is supported by the seat cushion 131 and serves as a backrest, and a reclining mechanism 133 that tilts the seat back 132 relative to the seat cushion 131.
[0037] The seat cushion 131 is mainly composed of a seat cushion frame that serves as a skeleton, a cushion pad provided on the seat cushion frame, and a surface covering that covers the seat cushion frame and the cushion pad. The seat back 132 is mainly composed of a seat back frame that serves as a framework, a cushion pad provided on the seat back frame, and a cover that covers the seat back frame and the cushion pad. The reclining mechanism 133 can tilt the seat back 132 relative to the seat cushion 131 to adjust it to any angle.
[0038] [Vehicle seats: dolly] The bogie 12 has a pair of left and right wheels 11 on the front and rear sides of the bottom, and a bogie frame 14 on top of which a seat 13 is detachably mounted. As shown in Fig. 5, the bogie frame 14 houses various components such as a wireless power receiving device 16 and a wired power receiving device 17. The bogie frame 14 is generally rectangular in plan view, and has connecting blocks 15 attached to each of the four upper corners thereof for connecting and holding the seat section 13.
[0039] The seat 13 of the bogie 12 can be replaced with various seat parts 13 of different sizes and shapes. For this reason, the connecting block 15 is formed with screw holes and screw insertion holes of different dimensions, and is configured so that it can be connected to various seat parts 13 using fastening members such as various screws and bolts. Therefore, the bogie 12 and the seat part 13 can be connected to and separated from each other. Furthermore, each connecting block 15 is attached to the upper surface of the bogie frame 14 via an adjustment mechanism 20 that allows the position of the connecting block 15 to be adjusted in three mutually perpendicular axial directions: front-rear, left-right, top-bottom. In other words, various seat sections 13 of different sizes and shapes may have different positions for the formation of screw holes and screw insertion holes, but by making the position of each connecting block 15 adjustable in any of the front-rear, left-right, top-bottom directions, it can be connected to various seat sections 13 of different sizes and shapes accordingly.
[0040] [Vehicle seats: connecting blocks and adjustment mechanisms] 6 is a perspective view of the adjustment mechanism 20. The adjustment mechanism 20 has a front-rear moving block 21 that is movable in the front-rear direction on the upper surface of the bogie frame 14, and a left-right moving block 22 that is movable in the left-right direction on the upper surface of the front-rear moving block 21, and supports the connecting block 15 on the upper surface of the left-right moving block 22 so that it can move up and down.
[0041] The longitudinally movable block 21 holds a ball nut 24 that is threaded onto a ball screw shaft (shown by a dashed line) 23 that is rotatably supported along the longitudinal direction on the upper surface of the bogie frame 14. The ball screw shaft 23 has a butterfly bolt structure, a bolt structure, a hexagonal hole, or the like formed at one end, and can be rotated manually or with a predetermined tool. As a result, the longitudinally movable block 21 that holds the ball nut 24 can move in the longitudinal direction on the upper surface of the bogie frame 14 and be positioned as desired.
[0042] The left-right moving block 22 holds a ball nut 26 that is threaded onto a ball screw shaft (shown by a dashed line) 25 that is rotatably supported along the left-right direction on the upper surface of the front-rear moving block 21. The ball screw shaft 25 has the same structure as the ball screw shaft 23 described above, and by rotating it, the left-right moving block 22 that holds the ball nut 26 can be moved left-right on the upper surface of the front-rear moving block 21 and positioned as desired.
[0043] The left-right moving block 22 also has a pair of protruding guide portions 221 that individually abut on the front and rear side end surfaces of the substantially rectangular parallelepiped connecting block 15. These guide portions 221, on the upper surface of the left-right moving block 22, restrict the rotation of the connecting block 15 about a ball screw shaft 27 (described later). Each guide portion 221 also allows the connecting block 15 to move up and down. It is preferable that the upper surface of the left-right moving block 22 is provided with a guide portion for restricting the left-right movement of the connecting block 15.
[0044] The connecting block 15 holds a ball nut 28 that is threaded onto a ball screw shaft (shown by a dashed line) 27 that is rotatably supported along the vertical direction on the upper surface of the left-right moving block 22. The ball screw shaft 27 has the same structure as the ball screw shaft 23 described above, and by rotating it, the connecting block 15 that holds the ball nut 28 can be moved in the vertical direction on the upper surface of the left-right moving block 22 and positioned as desired.
[0045] The four connecting blocks 15 can be moved and adjusted to any position in the front, back, left, right, up and down directions using their respective adjustment mechanisms 20, so that the screw holes or screw insertion holes of each connecting block 15 can be positioned with the screw insertion holes or screw holes on various seat sections 13, thereby effectively connecting the bogie 12 and seat section 13.
[0046] Each connecting block 15 is provided with a seat connection sensor 151 that detects whether or not the connecting block 15 is connected to the seat portion 13 (see FIG. 3). Any type of seat connection sensor 151 can be used as long as it can detect the connection state with the seat portion 13. For example, a limit switch or a proximity sensor can be used as the seat connection sensor 151. For example, if a limit switch is used as the seat connection sensor 151, the detection unit of the limit switch is disposed so as to cause a positional displacement in the vertical direction from the top surface of the connection block 15. Furthermore, if an optical proximity sensor is used, it is disposed so as to project detection light vertically from the top surface of the connection block 15. This makes it possible to detect whether there is a gap between the top surface of the connection block 15 and the seat portion 13, and to determine whether the connection state is appropriate.
[0047] [Vehicle seats: driving motor] The front, rear, left, and right wheels 11 mounted on the bottom of the bogie frame 14 are rotationally driven by a traveling motor 181 via a well-known power transmission mechanism. Power may be applied to only the two wheels 11 on the front or rear side. Separate traveling motors 181 are provided to drive the left and right wheels 11, and the vehicle seat 10 can be steered by the difference in rotational speed between the left and right wheels 11. The steering direction, running speed, start and stop of running, etc. of the vehicle seat 10 can be controlled by the user of the vehicle seat 10 by manually operating the operating device 182. The vehicle seat 10 may be driven by a single drive motor 181 and equipped with a known steering device to enable course change.
[0048] [Vehicle seat: power receiving coil and power receiving connector] 7 is a bottom view of the center of the bottom surface of the bogie frame 14, and FIG. 8 is a vertical cross-sectional view of the floor surface of the vehicle interior of the vehicle 100 with the vehicle seat 10 installed in the installation position. As shown in the figure, an opening 141 is formed in the center of the bottom side of the bogie frame 14, and inside this opening 141 are provided a receiving coil 161 as the receiving part of the wireless power receiving device 16 and a receiving connector 171 of the wired power receiving device 17. The power receiving side coil 161 is a coil that generates an induced electromotive force due to an induced magnetic flux generated when a current flows through the power transmitting side coil 91 (see FIG. 11) of the wireless power transmitting device 90 that faces the power receiving side coil 161 below. The power receiving side coil 161 is oriented in such a way that an induced electromotive force is effectively generated in the facing power transmitting side coil 91.
[0049] It should be noted that the power receiving coil 161 as a power receiving section directly supplies power to the power supply 184, but can also be said to indirectly supply power to various components that receive power from the power supply 184.
[0050] The power receiving connector 171 is a connector configured to be connectable to the power transmitting connector 121 of the wired power transmitting device 120 provided inside the vehicle 100. The power receiving connector 171 is attached in an orientation that allows connection by raising the power transmitting connector 121 from below. An emergency connector 172 is provided next to the power receiving connector 171. The emergency connector 172 is used to supply power from the emergency connector 172, for example, when the power source 184 of the vehicle seat 10 runs out of power while neither the wired power transmitting device 120 nor the wireless power transmitting device 90 is nearby. It is preferable that the emergency connector 172 be a connector that complies with widely available standards. This allows power to be supplied to the vehicle seat 10 through the emergency connector 172 from a commonly available, portable spare battery. The power receiving connector 171 and the emergency connector 172 are disposed inside the ring-shaped power receiving side coil 161 .
[0051] It should be noted that the power receiving connector 171 and the emergency connector 172 directly supply power to the power source 184, but can also be said to indirectly supply power to various components that receive power from the power source 184.
[0052] [Vehicle seats: shutter mechanism] The bogie frame 14 is provided with a shutter mechanism 30 that opens and closes the opening 141. The shutter mechanism 30 includes shutters 31 made of a pair of flat plates, and the pair of shutters 31 move toward and away from each other to open and close the opening 141. The pair of shutters 31 are supported slidably, for example, in the front-rear direction along a pair of slide rails 311 provided on the bottom surface of the bogie frame 14, and slide until their ends are abutted together, thereby closing the entire opening 141. Furthermore, the pair of shutters 31 can open the opening 141 when slid to the farthest position from each other, exposing the entire power receiving connector 171, the emergency connector 172, and the power receiving coil 161 downward.
[0053] By closing the opening 141 with the pair of shutters 31, the opening 141 can be made dustproof, drip-proof, and waterproof, and the receiving connector 171, emergency connector 172, and receiving coil 161 can be protected from external contact. It should be noted that a sealant may be provided to fill the gap between the pair of shutters 31 and the bogie frame 14. This makes it possible to more effectively prevent dust, drips, and water.
[0054] Furthermore, the pair of shutters 31 are formed with shield sections 312 made of a ferromagnetic material that does not allow magnetic flux to pass through, in a portion of the pair of shutters 31 that covers the power receiving connector 171 and the emergency connector 172 from below when the pair of shutters 31 are closed but does not cover the power receiving side coil 161. Furthermore, all portions of the pair of shutters 31 other than the shield sections 312 are made of a non-magnetic material that allows magnetic flux to pass through. As a result, when the pair of shutters 31 are open, the power transmitting connector 121 is connected from below to the power receiving connector 171 exposed downward, and power is supplied via wired power supply. Furthermore, when the pair of shutters 31 is closed, power is supplied wirelessly from below from the lower power transmitting coil 91 to the inner power receiving coil 161 through the pair of shutters 31. In this case, the power receiving connector 171 and the emergency connector 172 are shielded from below by the shielding portion 312 of the pair of shutters 31, and the influence of the magnetic flux generated from the power transmitting coil 91 on the power receiving connector 171 and the emergency connector 172 can be suppressed.
[0055] Fig. 9 is a side view showing the configuration of the shutter mechanism 30 that imparts opening and closing movement motion to the shutter 31 within the bogie frame 14. Note that Fig. 9 shows a configuration that imparts opening and closing movement motion to only the shutter 31 on one side, and the configuration that imparts opening and closing movement motion to the other shutter 31 is realized by arranging the configuration in Fig. 9 symmetrically, so illustration and description of the configuration will be omitted.
[0056] As shown in the figure, the shutter mechanism 30 has a link member 32 rotatably connected to one end of the shutter 31 in the movement direction, and a linear opening / closing actuator 33 that imparts a rotational movement to the link member 32. One end (lower end) of the link member 32 is rotatably connected to the downstream end in the movement direction (e.g., the front-to-rear direction) when the shutter 31 opens, around an axis along a direction perpendicular to the movement direction (e.g., the left-to-right direction). Furthermore, an elongated hole 321 is formed in the other end of the link member 32 along the longitudinal direction of the link member 32, over a length of at least half the entire length of the link member 32. A fulcrum shaft 34 fixed inside the bogie frame 14 is inserted into this elongated hole 321. This fulcrum shaft 34 is parallel to a direction perpendicular to the moving direction of the shutter 31. The opening / closing actuator 33 has a plunger 331 that moves back and forth along the movement direction of the shutter 31. The plunger 331 of the opening / closing actuator 33 is connected to the other end side of the link member 32 from the fulcrum shaft 34 by a pin 332 inserted into the elongated hole 321 of the link member 32 so as to be relatively movable along the elongated hole 321.
[0057] In the shutter mechanism 30 configured as described above, when the shutter 31 is closed, the plunger 331 of the opening / closing actuator 33 is arranged approximately vertically aligned with the fulcrum shaft 34, which causes the link member 32 to be in a substantially upright position (solid line in Figure 9). When the plunger 331 of the opening / closing actuator 33 is operated in the direction opposite to the direction in which the shutter 31 opens, the link member 32 rotates around the fulcrum shaft 34, and the shutter 31 connected to the end opposite to the plunger 331 moves in the opposite direction to the operating direction of the plunger 331, i.e., in the direction in which the shutter 31 opens (dotted line in Figure 9). The opening / closing actuator 33 and the fulcrum shaft 34 are positioned so as to maintain a constant height, but since they are connected to the elongated hole 321 of the link member 32, they move relatively along the elongated hole 321 and do not interfere with the rotational movement of the link member 32.
[0058] The opening / closing actuator 33 can be a solenoid or a linear motor. Alternatively, a rotary motor may be combined with a well-known conversion mechanism that converts rotary motion into linear motion. Alternatively, the shutter 31 may be opened or closed by combining a rotary motor with a rack-and-pinion mechanism. Furthermore, although the configuration in which an opening / closing actuator 33 is provided for each shutter 31 has been exemplified, the present invention is not limited to this, and a configuration in which one actuator rotates two link members 32 in opposite directions using gears or the like may also be used. Also, other mechanisms that impart opening and closing actions to each shutter 31 may be used, or a configuration in which one shutter 31 moves significantly to open and close the opening 141 may also be used.
[0059] 3, the shutter mechanism 30 is also provided with an open / close switch 35 for inputting an open / close operation. This open / close switch 35 is used to input an open / close operation command for the shutter 31 when power is supplied from the emergency connector 172. Note that instead of the open / close switch 35, an open / close means such as an operating lever for manually applying an open / close operation to the shutter 31 may be provided. In this case, the shutter 31 can be opened and closed even when the power of the power source 184 has completely run out and the open / close actuator 33 cannot be operated. The open / close switch 35 and the operating lever are preferably provided near the shutter 31.
[0060] 3, the shutter mechanism 30 is also provided with an operation selector switch 36. In principle, the opening and closing operation of the shutter 31 is performed automatically under the control of a connector connection detection unit 186a of the control unit 186, which will be described later. The operation selector switch 36 is a switch for switching between the above-mentioned automatic control of the opening and closing operation of the shutter 31 and manual operation using the above-mentioned opening and closing switch 35. In other words, in order to open and close the shutter 31 using the opening and closing switch 35, it is necessary to manually input the operation selector switch 36 in advance to cancel the automatic control state and switch to a state where manual operation is possible.
[0061] [Vehicle seat: communication device] The communication device 183 is a wireless communication device having a communication antenna. The communication device 183 may be compliant with wireless communication standards such as Wi-Fi (registered trademark) or Bluetooth (registered trademark). Note that the communication frequency of the communication device 183 should be selected to be a band different from the frequency used for wireless power feeding of the wireless power receiving device 16.
[0062] [Vehicle seats: power supplies and power supply circuits] The power source 184 for the vehicle seat 10 is a rechargeable battery, a capacitor, or the like. Examples of secondary batteries include nickel-cadmium batteries, nickel-metal hydride batteries, lithium-ion secondary batteries, lithium-ion polymer secondary batteries, and sodium-ion batteries.
[0063] The power supply circuit 185 has a rectifier circuit, a smoothing circuit, a switching circuit, etc., and converts the AC current generated from the power receiving side coil 161 due to wireless power feeding into a DC current, which is then converted into an appropriate voltage and supplied to each part. The power supply circuit 185 also has a DC-DC converter that converts the voltage of the DC current from the power supply 184, the power receiving connector 171, and the emergency connector 172, and a charging circuit that charges the power supply 184.
[0064] [Vehicle seat: lock sensor] As shown in FIG. 8, a locking mechanism 112 for holding the vehicle seat 10 in an appropriate position is provided inside the vehicle 100, and two or more insertion holes 142 are formed in the bottom surface of the bogie frame 14, as shown in FIG. 8, into which the lock pins 114 of the locking mechanism 112 are inserted from below. A lock sensor 187 is provided at the deepest part of the insertion hole 142 as a lock detection unit that detects whether the lock pin 114 is properly inserted and the vehicle seat 10 is locked. The lock sensor 187 can be any sensor that can detect the insertion state of the lock pin 114, such as a limit switch or pressure sensor that detects contact or pressure being applied to the lock pin 114 inserted into the insertion hole 142, or a proximity sensor that optically detects the location of the lock pin 114 inside the insertion hole 142. Furthermore, it is preferable that the lock sensor 187 be provided in each of the multiple insertion holes 142 .
[0065] [Vehicle seat: control unit] The control unit 186 is equipped with a CPU (Central Processing Unit), RAM (Random Access Memory), and ROM (Read Only Memory), and can control and process the power supply circuit 185 of the vehicle seat 10, the driving motor 181, the shutter mechanism 30, etc. The control unit 186 performs basic functions such as controlling the traveling motor 181 based on steering commands from the steering device 182, and also controls charging of the power source 184.
[0066] When the vehicle seat 10 moves into the wireless power supply area of the wireless power transmitting device 90 and an induced electromotive force is generated in the power receiving coil 161 due to the induced magnetic flux generated from the power transmitting coil 91, the charging control recognizes that power is being wirelessly supplied from the supply voltage and current of the power receiving coil 161, and charges the power source 184 using a charging circuit included in the power supply circuit 185. In addition, when the power transmitting connector 121 is connected to the power receiving connector 171 or when an external battery is connected to the emergency connector 172, the power receiving connector 171 or the emergency connector 172 recognizes that external charging is occurring from the supply voltage or current, and the power supply 184 is charged by the charging circuit included in the power supply circuit 185. As shown in FIG. 3, the control unit 186 also functions as a connector connection detection unit 186a, but the processing executed by the connector connection detection unit 186a will be explained after the configuration of the vehicle 100 has been explained.
[0067] [Vehicle: Overall configuration] As shown in FIG. 4, the vehicle 100 includes a driving motor 101 for driving the vehicle, a steering mechanism 102 for steering the vehicle 100, a wired power transmission device 120 for supplying power to the vehicle seat 10 via a wire at a predetermined position within the vehicle cabin, a locking mechanism 112 for keeping the vehicle seat 10 in a locked state at a predetermined position within the vehicle cabin, a camera 107 for photographing the surroundings of the vehicle 100 including the direction of travel, a positioning unit 108 for detecting the position of the vehicle 100, a direction sensor 109 for detecting the direction in which the vehicle 100 is facing, a communication device 103 for wireless communication with the outside, a display device 110 for displaying various information to the user (passenger), a power supply 104 as a power source for each part of the vehicle 100, a power supply circuit 105 for adjusting the power from the power supply 104 and supplying it to each part, and a control unit 106 for controlling and processing each part of the vehicle 100.
[0068] [Vehicle: Driving related] As described above, the vehicle 100 is an autonomous vehicle that can travel autonomously to a destination using the traction motor 101 as a drive source. The steering mechanism 102 is the same as a well-known steering mechanism mounted on a general automobile. However, the start and stop of travel, travel speed, travel direction, etc., caused by the traction motor 101 and the steering mechanism 102 are all fully controlled by the control unit 106.
[0069] The camera 107, the positioning unit 108, and the direction sensor 109 mounted on the vehicle 100 are all used for the autonomous running of the vehicle 100. The camera 107 is mounted facing the front of the vehicle 100 and captures images of the scene ahead in accordance with the direction of the vehicle 100. The camera 107 continuously captures images at a constant frame rate, and the captured images are input to an image processing device (not shown), which recognizes the road ahead, obstacles, and the like. The positioning unit 108 is a Global Navigation Satellite System (GNSS) receiver such as a Global Positioning System (GPS), and measures the current position of the vehicle 100 . The direction sensor 109 is a gyro azimuth sensor that detects the traveling direction of the vehicle 100 .
[0070] The control unit 106 controls the driving motor 101 and the steering mechanism 102 based on the current position indicated by the positioning unit 108 and the traveling direction of the vehicle 100 indicated by the direction sensor 109, thereby realizing automatic driving while following a course toward the destination. In addition, based on the road conditions obtained from the images captured by the camera 107, the driving motor 101 and the steering mechanism 102 make corrections to their operation during driving. It should be noted that a dedicated control device for performing automatic driving may be provided separately from the control unit 106.
[0071] [Vehicle: Wired power transmission device] FIG. 10 is a side view showing the configuration of a wired power transmitting device 120 that can provide a power transmitting connector 121 with a lifting and lowering action on the floor of the vehicle compartment. The power transmitting connector 121 is a connector that has a structure that allows it to be connected to a power receiving connector 171 of the wired power receiving device 17 that is provided on the bottom of the vehicle seat 10. The power transmitting connector 121 is attached in an orientation that allows it to be connected by lifting the power transmitting connector 121 from below toward the power receiving connector 171 when the vehicle seat 10 is parked in an appropriate position. The power transmitting connector 121 is connected to the power source 104 via the power supply circuit 105, and transmits an appropriate direct current at an appropriate voltage to the power receiving connector 171 through the power transmitting connector 121.
[0072] As shown in Fig. 8, the power transmitting connector 121 is supported on the floor of the vehicle compartment so as to be able to move up and down. As shown in Fig. 10, the wired power transmitting device 120 has an elbow-shaped link member 123 and a linear-acting lifting actuator 122 as a connector movable part that applies a rotational movement to the link member 123.
[0073] The elbow-shaped link member 123 is rotatably supported at a bent portion by a support shaft 127, and one end side of the link member 123 abuts against the bottom of the power transmitting connector 121 across the support shaft 127. In addition, an elongated hole 126 is formed in the other end of the link member 123. On the other hand, the lifting actuator 122 has a plunger 124 that moves linearly in the horizontal direction. The plunger 124 is connected to a pin 125 parallel to a support shaft 127 so as to be relatively movable along an elongated hole 126 of the link member 123.
[0074] In the above configuration, when the plunger 124 of the lifting actuator 122 protrudes, one end of the link member 123 is in a nearly horizontal, prone position. When the plunger 124 of the lifting actuator 122 retracts in the contracting direction, a rotational motion is imparted to the link member 123 via the pin 125 in the elongated hole 126. The one end of the link member 123 in the prone position then rotates up and down, pushing up the bottom of the power transmitting connector 121 and lifting the power transmitting connector 121 toward the power receiving connector 171 (indicated by the two-dot chain line in FIG. 10 ).
[0075] The plunger 124 of the lifting actuator 122 is positioned so as to maintain a constant height, but since the plunger 124 is connected to the elongated hole 126 of the link member 123, it moves relatively along the elongated hole 126 and does not interfere with the rotational movement of the link member 123. The lifting actuator 122 can be a solenoid or a linear motor. Alternatively, a rotary motor may be combined with a well-known conversion mechanism that converts rotary motion into linear motion. Alternatively, the lifting actuator 122 may be raised and lowered by combining a rotary motor with a rack-and-pinion mechanism.
[0076] [Vehicle: Locking mechanism] As shown in FIG. 8, on the floor of the vehicle compartment, at least on both sides of the wired power transmission device 120, locking mechanisms 112 for holding the vehicle seat 10 in an appropriate position are provided. Each lock mechanism 112 is composed of a linear actuator (e.g., a solenoid) and includes a main body 113 embedded in the floor of the vehicle compartment and a lock pin 114 that moves back and forth up and down from the main body 113.
[0077] When the vehicle seat 10 is stopped in the appropriate position, each insertion hole 142 of the bogie frame 14 and the lock pin 114 of each locking mechanism 112 are aligned in a plan view, and by protruding each lock pin 114 upward, it can be inserted into each insertion hole 142 of the bogie frame 14, and in this state the vehicle seat 10 can be held in the appropriate power supply position in the wired power transmission device 120 inside the vehicle cabin.
[0078] As mentioned above, the number of insertion holes 142 and locking mechanisms 112 may be increased. In addition, in order to prevent the lock pin 114 from accidentally coming out of the insertion hole 142, a through hole may be provided that passes through from the side surface of the bogie frame 14 to the lock pin 114, and a lock pin may be inserted into the through hole when the vehicle seat 10 is fixed. The movement of the lock pin 114 may be imparted by a combination of a rotational actuator and a transmission mechanism that converts rotation into linear movement.
[0079] [Vehicle: Display device] The display device 110 is for presenting various types of information to passengers in the vehicle, and includes a display for displaying images, characters, etc., an audio output means (speaker) for outputting audio, etc. The display device 110 may also be configured to use a touch panel display so that various input operations can be performed from the display device 110.
[0080] [Vehicle:Communication device] The communication device 103 is a wireless communication device having a communication antenna. The communication device 103 may be compliant with wireless communication standards such as Wi-Fi (registered trademark) or Bluetooth (registered trademark). Note that the communication frequency of the communication device 103 should be selected to be a band different from the frequency band used for wireless power feeding of the wireless power receiving device 16.
[0081] [Vehicle: Power supply and power circuit] The power source 104 of the vehicle 100 is an on-board battery, and may be a rechargeable secondary battery, capacitor, etc. Examples of secondary batteries include nickel-cadmium batteries, nickel-metal hydride batteries, lithium-ion secondary batteries, lithium-ion polymer secondary batteries, and sodium-ion batteries. The power supply circuit 105 has a DC-DC converter that converts the voltage of the direct current from the power supply 104 .
[0082] [Vehicle: Control unit] The control unit 106 includes a CPU, RAM, and ROM, and is capable of controlling and processing each of the above components of the vehicle 100. The control unit 106 performs basic functions for implementing automatic driving, as well as controls related to the vehicle seat 10. That is, as shown in FIG. 4, the control unit 106 functions as a wired power supply control unit 106a and a driving restriction control unit 106b. These are closely related to the connector connection detection unit 186a of the control unit 186 of the vehicle seat 10 described above, so we will first explain the processing performed by the connector connection detection unit 186a, and then explain the various processing performed by the wired power supply control unit 106a and the driving regulation control unit 106b.
[0083] [Processing of connector connection detection unit in vehicle seat] The connector connection detection unit 186a of the vehicle seat 10 performs processing when the vehicle seat 10 receives wired power supply from the wired power transmitting device 120 of the vehicle 100. The processing performed by the connector connection detection unit 186a is shown in the flowchart of FIG.
[0084] As shown in the figure, when a command to execute wired power supply is input from the control device 182 (step S1), the connector connection detection unit 186a first determines whether the seat unit 13 is properly connected to the carriage 12 using the seat connection sensor 151 (step S3). If there are multiple seat connection sensors 151, the determination is made based on all of the seat connection sensors 151.
[0085] As a result, if even one of the seat connection sensors 151 indicates an improper state, the connector connection detection unit 186a executes a notification process (step S5). The notification process, for example, involves notifying the control unit 106 of the vehicle 100 via the communication device 183 that the seat portion 13 is not properly connected to the bogie 12. The vehicle 100 controls the display device 110 to display that the seat portion 13 of the vehicle seat 10 is not properly connected to the bogie 12. This allows the passenger (user) to check the connection between the seat portion 13 and the bogie 12 and ensure that the connection is proper.
[0086] On the other hand, if it is determined in step S3 that the seat portion 13 is properly connected to the bogie 12, the connector connection detection unit 186a requests the control unit 106 of the vehicle 100 via the communication device 183 to perform a locking operation of the vehicle seat 10 using the locking mechanism 112 (step S7).
[0087] Then, the process waits for notification that the locking operation of the vehicle seat 10 by the locking mechanism 112 of the vehicle 100 has been completed (step S9), and when notification of locking completion is received from the control unit 106 of the vehicle 100, the connector connection detection unit 186a controls the opening / closing actuator 33 of the shutter mechanism 30 to open the shutter 31 (step S11).
[0088] Next, the connector connection detection unit 186a requests the control unit 106 of the vehicle 100 to connect the power transmitting connector 121 to the power receiving connector 171 (step S13). Then, the control unit 186 waits for a notification that the wired power transmission device 120 of the vehicle 100 has completed the lifting operation for connecting the power transmitting connector 121 (step S15), and upon receiving the notification, the control unit 186 checks whether the connectors are properly connected based on the supply voltage and current of the power receiving connector 171. In other words, the control unit 186 functions as a connector connection detection unit that detects the connection state of the power transmitting connector 121 and the power receiving connector 171. When it is recognized that the power transmitting connector 121 and the power receiving connector 171 are properly connected, the charging circuit included in the power supply circuit 185 controls charging of the power supply 184 (step S17).
[0089] If it is not recognized that the power transmitting connector 121 and the power receiving connector 171 are properly connected for a certain period of time or longer, an error may be reported through the communication device 183. In this case, when the control unit 106 of the vehicle 100 receives the error report, it is preferable that the control unit 106 displays a message reporting the error on the display device 110.
[0090] Then, the connector connection detection unit 186a notifies the control unit 106 of the vehicle 100 via the communication device 183 that the connectors have been properly connected and charging has started (step S19), and the process ends.
[0091] [Processing of the wired power supply control unit and driving regulation control unit in the vehicle] The processes performed by the wired power supply control unit 106a and the driving restriction control unit 106b in the vehicle 100 are executed in parallel with the process performed by the connector connection detection unit 186a of the vehicle seat 10. The process performed by the wired power supply control unit 106a is shown in the flowchart of FIG. 14, and the process performed by the driving restriction control unit 106b is shown in the flowchart of FIG.
[0092] 14, the wired power supply control unit 106a constantly monitors whether or not there is a request from the connector connection detection unit 186a to lock the vehicle seat 10 using the lock mechanisms 112 [the above-mentioned step S7] (step T1), and when a request for a locking operation is received, controls each lock mechanism 112 to project the lock pin 114 upward (step T3). This allows the vehicle seat 10 to be held in an appropriate wired power supply position within the vehicle compartment. Then, the wired power supply control unit 106a notifies the vehicle seat 10 of the completion of locking via the communication device 103 (step T5).
[0093] Next, the wired power feeding control unit 106a goes into a state of monitoring whether or not there is a request from the connector connection detection unit 186a to connect the power transmitting connector 121 to the power receiving connector 171 [the above-described step S13] (step T7). Then, upon receiving a request from the connector connection detection unit 186a to connect the power transmitting connector 121 to the power receiving connector 171, the wired power supply control unit 106a controls the lifting actuator 122 to lift the power transmitting connector 121 (step T9), and further notifies the communication device 103 that the lifting operation of the power transmitting connector 121 has been completed (step T11), thereby terminating the processing.
[0094] Furthermore, when the process by the wired power supply control unit 106a is completed, the process by the driving restriction control unit 106b is subsequently executed. That is, the driving regulation control unit 106b determines whether or not the vehicle 100 may start driving.
[0095] As shown in FIG. 15, the driving restriction control unit 106b monitors whether or not the connector connection detection unit 186a has notified the vehicle 100 of the start of charging [step S19 described above] (step T21). When the driving restriction control unit 106b receives the notification of the start of charging, it terminates the driving restriction state and sets the vehicle 100 to a driving-permitted state (step T23), and drives the driving motor 101 to start the vehicle 100 moving (step T25). Then, the process ends.
[0096] [Wireless power transmission device] 11 is a block diagram showing the configuration of a wireless power transmitting device 90. As shown in the figure, the wireless power transmitting device 90 has a power transmitting coil 91 placed on an outdoor road surface, and a power transmitting circuit 93 that supplies AC current of a predetermined frequency from an AC power source 92 to the power transmitting coil 91. The power transmitting circuit 93 has an inverter circuit that converts the AC current of the power source 92 into AC current of the predetermined frequency. With this configuration, when the vehicle seat 10 approaches the power transmission coil 91 placed on the road surface, an electromotive force is generated in the power receiving coil 161 of the vehicle seat 10 through the induced magnetic flux generated in the power transmission coil 91, and power is supplied.
[0097] During wireless power feeding, the shutter mechanism 30 of the vehicle seat 10 keeps the shutter 31 closed, but the shutter 31 is made of a non-magnetic material that transmits magnetic flux, allowing for good wireless power feeding. Furthermore, the power receiving connector 171 and the emergency connector 172 of the vehicle seat 10 are shielded on the power transmitting coil 91 side by the shield portion 312 of the shutter 31, so the effects of the magnetic flux generated from the power transmitting coil 91 can be suppressed.
[0098] [Technical Effects of the Invention Embodiments] As described above, the vehicle seat 10 is equipped with the wireless power receiving device 16 and the wired power receiving device 17 that supply power to the traction motor 181 and the rechargeable power source 184, which increases the degree of freedom in the method of receiving power supply, and is not limited to power supply from limited power supply equipment, making it possible to improve the versatility of the use of the vehicle seat 10.
[0099] Furthermore, since the vehicle seat 10 is equipped with wheels 11 and a driving motor 181 that drives the wheels 11, it is possible to move outside the vehicle 100. Combined with the effect of improving the flexibility of the power supply method, and with the simplification of power supply outdoors, it is possible to further improve the versatility of the vehicle seat 10 for outdoor activities.
[0100] The vehicle seat 10 also includes a connecting block 15 that connects the bogie 12 and the seat portion 13, and the connecting block 15 is supported by an adjustment mechanism 20 so that its position can be adjusted in three axial directions relative to the seat portion 13, and can be connected to and separated from the seat portion 13. Therefore, even if the seat portion 13 has various sizes or structures, it can be connected to the bogie 12, a variety of people can sit in the seat portion 13, and the seat portion 13 can be used to suit a variety of uses.
[0101] The vehicle seat 10 also includes a shutter mechanism 30 having an openable / closable shutter 31 at the opening 141 where the power receiving coil 161 of the wireless power receiving device 16 and the power receiving connector 171 of the wired power receiving device 17 are provided. As a result, when the power receiving connector 171 is not in use, the shutter 31 can be kept closed to improve the dustproof, drip-proof, and waterproof properties of the opening 141, as well as protection from external contact, and the power receiving coil 161 and the power receiving connector 171 can be effectively protected. In particular, in the case of a power feeding system 1 in which the wireless power transmitting device 90 is located outdoors, the presence of the shutter 31 makes it possible to more effectively protect the power receiving coil 161 and the power receiving connector 171.
[0102] Furthermore, the vehicle seat 10 has an opening 141 provided in the bottom of the vehicle seat 10, the power receiving coil 161 of the wireless power receiving device 16 can receive power wirelessly from below, and the power receiving connector 171 of the wired power receiving device 17 can be connected to the power transmitting connector 121 from below. In such a configuration, by placing the wireless power transmitting device 90 and the wired power transmitting device 120 on the road surface or floor, it becomes possible to easily receive power simply by moving the vehicle seat 10 to an appropriate power feeding position, thereby improving the convenience of the vehicle seat 10.
[0103] Furthermore, the vehicle seat 10 can receive power wirelessly even when the power receiving coil 161 of the wireless power receiving device 16 is in a closed state of the shutter 31, thereby further enhancing the effects of dustproofing, drip-proofing, waterproofing, and protection from external contact. In particular, in the case of a power feeding system 1 in which the wireless power transmitting device 90 is located outdoors, the power receiving coil 161 and the power receiving connector 171 can be protected more effectively.
[0104] Furthermore, the vehicle seat 10 is provided with a power source consisting of a rechargeable battery, allowing for free movement with fewer restrictions, and the recharging function also makes it possible to expand the range of movement. In particular, in the case of a power supply system 1 that includes a wired power transmission device 120 installed in the vehicle 100 and a wireless power transmission device 90 installed outside (outdoors) of the vehicle 100, it is possible to ensure a wider range of free movement.
[0105] In addition, the vehicle 100 is equipped with a wired power transmission device 120 that supplies power from the power receiving connector 171 of the wired power receiving device 17 of the vehicle seat 10 through the power transmitting connector 121, so that power can be supplied to the vehicle seat 10 while traveling in the vehicle 100, and the vehicle seat 10 can be used to travel to the destination, making it easy to operate the vehicle seat 10 over a wide range. Furthermore, when power is supplied via a wire, a large capacity of power can be supplied, and charging can be performed at high speed, which further improves the convenience of the vehicle seat 10.
[0106] In addition, the vehicle 100 is equipped with a locking mechanism 112 that fixes the vehicle seat 10 inside the vehicle cabin, so that the vehicle seat 10 can be fixed inside the vehicle cabin, and the vehicle seat 10 can be appropriately used as a passenger seat for the vehicle 100. In particular, if the vehicle 100 is an automatically driven vehicle, seats suitable for driving are not required, so all the seats in the vehicle cabin can be vehicle seats 10, allowing more vehicle seats 10 to be installed and increasing the number of people who can use the vehicle seats 10.
[0107] Furthermore, the vehicle 100 includes a wired power feeding control unit 106a that controls the lifting / lowering actuator 122 to connect the power transmitting connector 121 to the power receiving connector 171 when the lock sensor 187 detects that the vehicle seat 10 has been fixed by the locking mechanism 112. This allows the locking mechanism 112 to optimize the position of the vehicle seat 10, and the power transmitting connector 121 and the power receiving connector 171 to be automatically connected by the lifting / lowering actuator 122. This eliminates the need for manual connector connection, dramatically improving convenience. In particular, the insertion hole 142 for the lock pin 114 in the bogie frame 14 of the vehicle seat 10 is formed in a conical shape with an enlarged diameter opening on the lock pin 114 side, so that even if the vehicle seat 10 is parked at an approximate stopping position, the lock pin 114 can be inserted into the insertion hole 142, and the vehicle seat 10 can be easily secured by the lock mechanism 112.
[0108] Furthermore, the vehicle 100 is equipped with a driving restriction control unit 106b that detects the connection state between the seat portion 13 of the vehicle seat 10 and the bogie 12 and the connection state between the power transmitting connector 121 and the power receiving connector 171 through the control of the connector connection detection unit 186a and the wired power supply control unit 106a, and allows the vehicle to travel when the lock sensor 187 detects that the locking mechanism 112 has been secured. This allows the vehicle seat 10 to be properly secured in the vehicle interior while the vehicle is traveling. Also, power can be properly supplied while the vehicle is traveling. In addition, the driving restriction control unit 106b also recognizes the proper connection state determined by the seat connection sensor 151 through the control of the wired power supply control unit 106a, so that the vehicle seat 10 can be driven in a state where it is more properly fixed within the vehicle cabin.
[0109] [others] 12, the vehicle seat 10 may be configured so that the seat back 132 can be tilted to a nearly horizontal position with respect to the seat cushion 131 by a reclining mechanism 133, and the upper surface (rear surface) of the horizontal seat back 132 can be used as a table. This further improves the versatility of the vehicle seat 10. Furthermore, in this case, electrical components that provide new functions may be mounted on the vehicle seat 10. Examples of electrical components include a display, a speaker, a heater, a blower, and an output connector that supplies power to the outside, but other electrical components may also be mounted. This makes it possible to enhance the functionality and versatility of the vehicle seat 10.
[0110] In addition, in the above embodiment, an example was shown in which the adjustment mechanism 20 supports the connecting block 15 so that its position can be adjusted in three axial directions (up and down, left and right, and front and back), but the abutment mechanism 20 may also be configured to support the connecting block 15 so that its position can be adjusted in two axial directions (front and back, left and right).
[0111] 2 shows a configuration in which a plurality of vehicle seats 10 are installed in the vehicle 100, all of which are secured by locking mechanisms 112. While FIG. 2 illustrates a configuration in which a wired power transmission device 120 is installed to supply power to only one vehicle seat 10 in the vehicle 100, a plurality of wired power transmission devices 120 may be installed. For example, it is preferable to install the same number of wired power transmission devices 120 as the number of vehicle seats 10 that can be installed.
[0112] Furthermore, in the above embodiment, the vehicle 100 is an autonomous vehicle, but the vehicle 100 may be a vehicle driven by a human being.
