By doing so, it is possible to connect various seat portions 13 having different sizes and shapes correspondingly.

[Vehicle seat: connecting block and adjustment mechanism]
FIG. 6 is a perspective view of the adjustment mechanism 20. FIG. The adjustment mechanism 20 has a front-rear movement block 21 that can move in the front-rear direction on the upper surface of the bogie frame 14 and a left-right movement block 22 that can move in the left-right direction on the upper surface of the front-rear movement block 21 . The upper surface supports the connection block 15 so as to be vertically movable.

The longitudinal movement block 21 holds a ball nut 24 screwed onto a ball screw shaft (illustrated by a dashed line) 23 rotatably supported in the longitudinal direction on the upper surface of the bogie frame 14 . One end of the ball screw shaft 23 is formed with a butterfly bolt structure, a bolt structure, a hexagonal hole, or the like, and can be rotated manually or with a predetermined tool. As a result, the longitudinally movable block 21 holding the ball nut 24 can be moved longitudinally on the upper surface of the bogie frame 14 and positioned arbitrarily.

The left-right movement block 22 holds a ball nut 26 screwed onto a ball screw shaft (illustrated by a dashed line) 25 rotatably supported in the left-right direction on the upper surface of the front-rear movement 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 holding the ball nut 26 can be moved in the left/right direction on the upper surface of the front/rear moving block 21 and arbitrarily positioned. can be done.

The left-right movement block 22 also has a pair of projecting guide portions 221 that individually abut against the front and rear side end surfaces of the substantially rectangular parallelepiped connecting block 15 . These guide portions 221 regulate the rotation of the connecting block 15 about a ball screw shaft 27 described later on the upper surface of the laterally moving block 22 . Further, each guide portion 221 allows vertical movement of the connecting block 15 .
In addition, it is preferable that a guide portion for restricting the movement of the connecting block 15 in the left-right direction is also provided on the upper surface of the left-right movement block 22 .

The connecting block 15 holds a ball nut 28 screwed onto a ball screw shaft (illustrated by a dashed line) 27 rotatably supported in the vertical direction on the upper surface of the left/right moving block 22 .

Since the four connecting blocks 15 can be moved and adjusted to arbitrary positions in the front, rear, left, right, up and down directions by their respective adjustment mechanisms 20, various screws on the side of the seat portion 13 can be inserted through the screw holes or screw insertion holes of the respective connection blocks 15. It can be positioned in holes or screw holes to effectively connect the carriage 12 and the seat 13 .

Each connecting block 15 is provided with a seat connecting sensor 151 for detecting whether or not the connecting block 15 is connected to the seat portion 13 (see FIG. 3).
The seat connection sensor 151 may be of any type as long as it can detect the connection state with the seat portion 13 . As the seat connection sensor 151, for example, a limit switch or a proximity sensor can be used. For example, when a limit switch is used as the seat connection sensor 151 , the detector of the limit switch is provided so as to cause displacement in the vertical direction from the upper surface of the connection block 15 . Also, when an optical proximity sensor is used, it is provided so as to project detection light vertically from the upper surface of the connecting block 15 .

[Vehicle seat: power receiving side coil and power receiving connector]
FIG. 7 is a bottom view of the central portion of the bottom surface of the bogie frame 14, and FIG. 8 is a vertical cross-sectional view of the vehicle interior floor of the vehicle 100 in which the vehicle seat 10 is installed at the installation position.
As shown in the figure, an opening 141 is formed in the central portion of the bottom side of the bogie frame 14, and a power receiving side coil 161 as a power receiving portion of the wireless power receiving device 16 and a wired power receiving device are provided inside the opening 141. 17 power receiving connectors 171 are provided.
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 arranged in such a direction that an induced electromotive force is effectively generated with respect to the opposing power transmitting side coil 91 .

Note that the power receiving side coil 161 as a power receiving unit directly supplies power to the power supply 184, but it also indirectly supplies power to various components to which power is supplied from the power supply 184. I can say.

Power receiving connector 171 is a connector that can be connected to power transmitting connector 121 of wired power transmitting device 120 provided inside vehicle 100 . The power receiving connector 171 is attached in such a direction that it can be connected 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 for supplying power from the emergency connector 172 when, for example, the power supply 184 of the vehicle seat 10 runs out while neither the wired power transmission device 120 nor the wireless power transmission device 90 is nearby. belongs to. The emergency connector 172 is preferably a connector conforming to widely distributed standards. This allows power to be supplied to the vehicle seat 10 through the emergency connector 172 from a widely available portable spare battery.
The power receiving connector 171 and the emergency connector 172 are arranged inside the annular power receiving side coil 161 .

The power receiving connector 171 and the emergency connector 172 directly supply power to the power supply 184, but also indirectly supply power to various components to which power is supplied from the power supply 184. I can say.

[Vehicle seat: Shutter mechanism]
The bogie frame 14 is provided with a shutter mechanism 30 for opening and closing the opening 141 . The shutter mechanism 30 includes a pair of flat plate shutters 31 , and the opening 141 can be opened and closed by moving the pair of shutters 31 toward and away from each other.
The pair of shutters 31 are slidably supported, 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 are slidable until their ends meet each other. By doing so, the entire opening 141 is closed. Also, the pair of shutters 31 can open the opening 141 while being slid to the maximum distance from each other, thereby exposing the power receiving connector 171, the emergency connector 172 and the power receiving side coil 161 as a whole.

By closing the opening 141 with the pair of shutters 31, the opening 141 is dustproof, dripproof, and waterproof, and the power receiving connector 171, the emergency connector 172, and the power receiving side coil 161 are protected from contact objects from the outside. can do.
A sealing material may be provided between the pair of shutters 31 and the bogie frame 14 to fill the gap. This makes it possible to achieve more effective dustproof, dripproof, and waterproof properties.

Further, the pair of shutters 31 is a ferromagnetic material that does not allow magnetic flux to pass through a portion that covers the power receiving connector 171 and the emergency connector 172 from below and does not cover the power receiving side coil 161 when the pair of shutters 31 is closed. A shield portion 312 made of is formed. In addition, all portions of the pair of shutters 31 other than the shield portion 312 are made of a non-magnetic material that transmits magnetic flux.
As a result, the power transmission connector 121 is connected from below to the power reception connector 171 exposed downward when the pair of shutters 31 are open, and power is supplied by wired power supply.
Further, power is supplied from below to the inner power receiving coil 161 from the lower power transmitting coil 91 through the pair of shutters 31 while the pair of shutters 31 are closed. In this case, the power receiving connector 171 and the emergency connector 172 are shielded from below by the shield portions 312 of the pair of shutters 31, and the influence of the magnetic flux generated from the power transmission side coil 91 on the power receiving connector 171 and the emergency connector 172 can be suppressed. .

FIG. 9 is a side view showing the construction of the shutter mechanism 30 that imparts opening and closing movement to the shutter 31 within the bogie frame 14. As shown in FIG. Note that FIG. 9 shows a configuration in which only the shutter 31 on one side is opened and closed, and the configuration in which the opening and closing movement is imparted to the other shutter 31 is bilaterally symmetrical to the configuration in FIG. , so illustration and description are omitted.

As shown in the drawing, the shutter mechanism 30 includes a link member 32 rotatably connected at one end in the moving direction of the shutter 31 , and a direct-acting open/close actuator 33 that imparts a rotative motion to the link member 32 . have
One end (lower end) of the link member 32 extends along a direction perpendicular to the movement direction (for example, the left-right direction) with respect to the downstream end of the movement direction (for example, the front-rear direction) when the shutter 31 is opened. are connected so as to be rotatable about an axis.
Further, at the other end of the link member 32, an elongated hole 321 along the longitudinal direction of the link member 32 is formed over half or more of the entire length of the link member 32. As shown in FIG. A fulcrum shaft 34 fixed inside the bogie frame 14 is inserted through the elongated hole 321 . The fulcrum shaft 34 is parallel to the direction orthogonal to the moving direction of the shutter 31 .
The opening/closing actuator 33 has a plunger 331 that advances and retreats along the moving direction of the shutter 31 . The plunger 331 of the opening/closing actuator 33 is relatively movable along the elongated hole 321 by a pin 332 inserted through the elongated hole 321 of the link member 32 on the other end side of the link member 32 relative to the fulcrum shaft 34 . Concatenated.

The shutter mechanism 30 configured as described above is arranged so that the plunger 331 of the opening/closing actuator 33 is aligned substantially vertically with the fulcrum shaft 34 when the shutter 31 is closed. (solid line in FIG. 9).
When the plunger 331 of the open/close actuator 33 is operated in the direction opposite to the direction in which the shutter 31 opens, the link member 32 rotates about the fulcrum shaft 34 and moves to the end opposite to the plunger 331 . The coupled shutter 31 moves in the direction opposite to the operating direction of the plunger 331, that is, in the direction in which the shutter 31 is opened (two-dot chain line in FIG. 9).
The opening/closing actuator 33 and the fulcrum shaft 34 are arranged so as to maintain a constant height. Since they move relatively, they do not interfere with the rotation of the link member 32 .

A solenoid or a direct-acting motor can be used as the opening/closing actuator 33 . Further, a well-known conversion mechanism that converts rotary motion into linear motion may be combined with the rotary motor. Alternatively, the shutter 31 may be opened and closed by a combination of a rotary motor and a rack-and-pinion mechanism.
Further, although the configuration in which the opening/closing actuator 33 is provided for each shutter 31 is illustrated, the configuration is not limited to this, and a configuration in which the two link members 32 are rotated in opposite directions by one actuator using a gear or the like is also possible. good. Further, another mechanism that imparts an opening/closing operation to each shutter 31 may be used, or a configuration in which one shutter 31 moves greatly to open and close the opening 141 may be used.

In addition, as shown in FIG. 3, the shutter mechanism 30 is provided with an opening/closing switch 35 for inputting an opening/closing operation. The opening/closing switch 35 is for inputting an opening/closing operation command for the shutter 31 when power is supplied from the emergency connector 172 . Instead of the opening/closing switch 35, an opening/closing means such as an operating lever for manually imparting an opening/closing operation to the shutter 31 may be provided. In this case, the shutter 31 can be opened and closed even when the power supply 184 runs out completely and the open/close actuator 33 cannot be operated.
It is desirable that the opening/closing switch 35 and the operating lever are provided near the shutter 31 .

The shutter mechanism 30 is also provided with an operation changeover switch 36, as shown in FIG. In principle, the opening and closing operation of the shutter 31 is automatically performed under the control of a connector connection detector 186a of the control unit 186, which will be described later. The operation changeover switch 36 is a switch for switching the opening/closing operation of the shutter 31 between automatic control and manual operation by the opening/closing switch 35 . In other words, in order to open/close the shutter 31 with the open/close switch 35, it is necessary to manually input the operation changeover switch 36 in advance to cancel the automatic control state and switch to the manual operable state.
