[0012] A preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings. The dimensions, materials, and other specific values ​​shown in the embodiment are merely examples for facilitating understanding of the invention, and do not limit the present invention unless otherwise specified. In this specification and drawings, elements having substantially the same functions and configurations are given the same reference numerals to avoid repeated explanations, and elements not directly related to the present invention are not shown.

[0013] [Power generation system 100] 1 is a schematic perspective view of a power generation system 100 according to this embodiment. As shown in FIG.

[0014] The vehicle 200 (automobile) has a solar power generation device 202. The solar power generation device 202 is provided, for example, on the roof (ceiling) of the vehicle 200. The solar power generation device 202 generates power by utilizing light energy (sunlight) from the sun 10.

[0015] The building 300 is, for example, an office building, and is used as a workplace (workplace). A user, such as an employee commuting to the workplace, drives the vehicle 200 to travel between his / her home and the building 300.

[0016] In the power generation system 100 of this embodiment, a side wall 310 on the south side of a building 300 is used as a parking space S for a vehicle 200. The side wall 310 of the building 300 has an inclined surface 312 that is inclined with respect to the ground. The inclination angle of the inclined surface 312 is the angle between the horizontal direction of the ground and a vertical direction perpendicular to the ground. The inclination angle of the inclined surface 312 is, for example, 45 degrees. However, the inclination angle is not limited to this, and may be 90 degrees perpendicular to the ground.

[0017] A transport mechanism 320 is provided on the side wall 310 of the building 300. The transport mechanism 320 is configured to be able to move the vehicle 200 on the inclined surface 312 of the side wall 310. The transport mechanism 320 is provided to extend from the lower end (ground) to the upper end (rooftop) of the side wall 310. As shown in FIG. 1, a plurality of transport mechanisms 320 are provided in the width direction of the side wall 310.

[0018] The transport mechanism 320 of this embodiment holds the vehicle 200 and raises or lowers the vehicle 200 along the side wall 310. One transport mechanism 320 can hold a plurality of vehicles 200 in the longitudinal direction. The position of the vehicle 200 held on the side wall 310 (on the inclined surface 312) by the transport mechanism 320 is effectively used as a parking space S.

[0019] The power generation system 100 of this embodiment supplies power generated by a solar power generation device 202 of a vehicle 200 parked in a parking space S to a building 300. The transport mechanism 320 and the power supply mechanism 250 will be described below.

[0020] [Transport mechanism 320] Fig. 2 is a schematic cross-sectional view of the transport mechanism 320 in the power generation system 100 of this embodiment. As shown in Fig. 2, the vehicle 200 includes a first engaged part 210, a second engaged part 220, a third engaged part 230, and a drive mechanism (not shown).

[0021] The first engaged portion 210 is configured to be capable of protruding and retracting from the front end FE of the front portion F. The second engaged portion 220 is configured to be capable of protruding and retracting from the lower end LE of the front portion F. The third engaged portion 230 is configured to be capable of protruding and retracting from the lower end LE of the rear portion R. The first engaged portion 210 and the second engaged portion 220 are located on the front side of the front wheels of the vehicle 200, and the third engaged portion 230 is located on the rear side of the rear wheels of the vehicle 200.

[0022] The first engaged part 210, the second engaged part 220, and the third engaged part 230 are configured, for example, from a metal member formed into a U-shape. The first engaged part 210, the second engaged part 220, and the third engaged part 230 are driven in the protruding direction and the retracting direction by a driving mechanism such as, for example, an electric motor, an electric cylinder, a hydraulic motor, or a hydraulic cylinder.

[0023] In addition, although details will be described later, in this embodiment, the second engaged portion 220 has a first connection terminal that supplies the electricity generated by the solar power generation device 202 to the building 300.

[0024] 2, when the vehicle 200 approaches within a predetermined distance of the side wall 310 (inclined surface 312) of the building 300, the first engaged portion 210 protrudes from the front end FE, and the second engaged portion 220 and the third engaged portion 230 protrude from the lower end LE. When the vehicle 200 moves away from the side wall 310 of the building 300 by a predetermined distance or more, the first engaged portion 210 retracts from the front end FE, and the second engaged portion 220 and the third engaged portion 230 retract from the lower end LE.

[0025] In the vehicle 200 of this embodiment, the first engaged portion 210, the second engaged portion 220, and the third engaged portion 230 are automatically protruded and retracted by a drive mechanism. However, the present invention is not limited to this, and the vehicle 200 may be configured such that the first engaged portion 210, the second engaged portion 220, and the third engaged portion 230 are manually protruded and retracted by, for example, a passenger.

[0026] 2, the transport mechanism 320 includes a first engaging portion 322, a second engaging portion 324, a third engaging portion 326, and a movable portion 328. The first engaging portion 322 is configured to be able to engage with a first engaged portion 210 of the vehicle 200. The second engaging portion 324 is configured to be able to engage with a second engaged portion 220 of the vehicle 200. The third engaging portion 326 is configured to be able to engage with a third engaged portion 230 of the vehicle 200.

[0027] In addition, although details will be described later, in this embodiment, the second engagement portion 324 has a second connection terminal. The second engagement portion 324 is configured so that, when engaged with the second engaged portion 220 of the vehicle 200, a first connection terminal of the second engaged portion 220 and a second connection terminal of the second engagement portion 324 are connected (contacted).

[0028] 2 shows a state in which the first engaging portion 322 and the first engaged portion 210 are engaged with each other. For example, the vehicle 200 can engage the first engaged portion 210 with the first engaging portion 322 by automatically moving close to the transport mechanism 320 with the first engaged portion 210 protruding.

[0029] The movable part 328 is configured by, for example, an endless wire. However, without being limited thereto, the movable part 328 may be configured by an endless belt or an endless chain. The movable part 328 moves the first engagement part 322, the second engagement part 324, and the third engagement part 326 in a forward direction R1 or a backward direction R2 along the inclined surface 312. The forward direction R1 is a direction from the lower end to the upper end of the side wall 310, and the backward direction R2 is a direction from the upper end to the lower end of the side wall 310.

[0030] Fig. 3 is a schematic enlarged view of the first engagement portion 322 of the transport mechanism 320. As shown in Fig. 3, the first engagement portion 322 includes a fixed portion 322a and an inclined portion 322b. The fixed portion 322a is fixed to the movable portion 328. The inclined portion 322b is connected to the fixed portion 322a, and at least a portion of the inclined portion 322b is exposed (protrudes) to the outside of the side wall 310 (inclined surface 312) (see Fig. 2).

[0031] The inclined portion 322b is inclined with respect to the traveling direction R1 of the movable portion 328. Specifically, the inclined portion 322b extends at an incline in a direction between the traveling direction R1 of the movable portion 328 and an orthogonal direction R3 perpendicular to the traveling direction R1. The tip side of the inclined portion 322b is located closer to the traveling direction R1 than the base end connected to the fixed portion 322a.

[0032] 4 is a schematic enlarged view of the second engagement portion 324 of the transport mechanism 320. In this embodiment, the second engagement portion 324 and the third engagement portion 326 have the same shape, so a detailed description of the third engagement portion 326 will be omitted.

[0033] 4, the second engagement portion 324 includes a fixed portion 324a, an inclined portion 324b, and a curved portion 324c. The fixed portion 324a is fixed to the movable portion 328. The inclined portion 324b is connected to the fixed portion 324a via the curved portion 324c, and at least a portion of the inclined portion 324b is exposed (protrudes) to the outside of the side wall 310 (inclined surface 312) (see FIG. 2).

[0034] The inclined portion 324b is inclined with respect to the traveling direction R1 of the movable portion 328. Specifically, the inclined portion 324b extends at an incline in a direction between the traveling direction R1 of the movable portion 328 and an orthogonal direction R3 perpendicular to the traveling direction R1. The tip side of the inclined portion 324b is located closer to the traveling direction R1 than the base end connected to the curved portion 324c.

[0035] The curved portion 324c has one end connected to the fixed portion 322a and the other end connected to the inclined portion 322b. That is, the curved portion 324c is located between the fixed portion 324a and the inclined portion 324b. The curved portion 324c extends from the fixed portion 322a in the perpendicular direction R3 and curves toward the traveling direction R1. When the curved portion 324c engages with the second engaged portion 220, the curved portion 324c restricts the movement of the second engaged portion 220 so as not to separate from the fixed portion 324a.

[0036] Fig. 5 is a diagram showing a state in which the movable part 328 has moved in the traveling direction R1 from the state of the vehicle 200 and the transport mechanism 320 shown in Fig. 2. As shown in Fig. 5, when the first engaging part 322 moves in the traveling direction R1 while engaged with the first engaged part 210, it lifts up the front part F of the vehicle 200. This makes it easier for the second engaging part 324 and the second engaged part 220 to engage with the third engaging part 326 and the third engaged part 230 than when the front part F of the vehicle 200 is not lifted.

[0037] 6 is a diagram showing a state in which the movable part 328 has moved in the traveling direction R1 from the state of the vehicle 200 and the transport mechanism 320 shown in FIG. 5. As shown in FIG. 6, when the first engaging part 322 moves further in the traveling direction R1 with the front part F of the vehicle 200 being lifted, the second engaged part 220 enters the gap between the inclined part 324b and the fixed part 324a (see FIG. 4) of the second engaging part 324. As a result, the second engaging part 324 engages with the second engaged part 220. At this time, the vehicle 200 may control the drive mechanism to adjust the protruding amount of the second engaged part 220.

[0038] 7 is a diagram showing a state in which the movable part 328 has moved in the traveling direction R1 from the state of the vehicle 200 and the transport mechanism 320 shown in FIG. 6. As shown in FIG. 7, when the first engaging part 322 moves further in the traveling direction R1 side in a state in which the second engaging part 324 and the second engaged part 220 are engaged with each other, the third engaged part 230 enters the gap between the inclined part 324b and the fixed part 324a (see FIG. 4) of the third engaging part 326. As a result, the third engaging part 326 engages with the third engaged part 230. At this time, the vehicle 200 may control the drive mechanism to adjust the protruding amount of the third engaged part 230.

[0039] 4 and 6, the second engaged portion 220 first enters the gap between the inclined portion 324b and the fixed portion 324a of the second engaging portion 324 and comes into contact with the inclined portion 324b. Then, the second engaged portion 220 moves from the inclined portion 324b toward the curved portion 324c due to the weight of the vehicle 200.

[0040] 4 and 7, the third engaged portion 230 first enters the gap between the inclined portion 324b and the fixed portion 324a of the third engaging portion 326 and comes into contact with the inclined portion 324b. Then, the third engaged portion 230 moves from the inclined portion 324b toward the curved portion 324c due to the weight of the vehicle 200.

[0041] Here, the closer the inclined portion 322b is to the curved portion 324c, the closer it is to the fixed portion 322a. Therefore, when the second engaged portion 220 and the third engaged portion 230 move from the inclined portion 322b toward the curved portion 324c, they move in a direction approaching the fixed portion 322a. In other words, when the second engaged portion 220 and the third engaged portion 230 move from the inclined portion 322b toward the curved portion 324c, they move in a direction approaching the inclined surface 312.

[0042] As a result, the vehicle 200 is pressed against the inclined surface 312 of the side wall 310, and is less likely to move in a direction away from the inclined surface 312. As a result, the transport mechanism 320 can transport the vehicle 200 stably, and can park the vehicle 200 in the parking space S stably.

[0043] As described above, the building 300 of this embodiment is, for example, an office building, and the vehicle 200 is, for example, a shared car. The transport mechanism 320 parks the vehicle 200 as a shared car on the side wall 310 of the building 300. When parking the shared car (vehicle 200) on the side wall 310 of the building 300, the transport mechanism 320 parks the shared car (vehicle 200) in the parking space S one by one in sequence from the ground side (bottom) to the rooftop side (top). At this time, the transport mechanism 320 moves the movable part 328 in the traveling direction R1 to raise the vehicle 200 from the ground side to the rooftop side in the order of FIG. 5, FIG. 6, and FIG. 7.

[0044] On the other hand, when a user attempts to get into the vehicle 200 parked in the parking space S of the side wall 310, the transport mechanism 320 lowers the vehicles 200 one by one from the bottom to the ground. At this time, the transport mechanism 320 moves the movable part 328 in the backward direction R2 to lower the vehicles 200 from the rooftop side to the ground side in the order of FIG. 7, FIG. 6, and FIG. 5.

[0045] When the transport mechanism 320 lifts and lowers the vehicle 200, the shift position of the vehicle 200 is switched to, for example, neutral. In this embodiment, when the vehicle 200 is located near the parking position (near the side wall 310), the vehicle 200 automatically controls the shift position to neutral. However, this is not limited to this, and when the vehicle 200 is located near the parking position, the shift position of the vehicle 200 may be manually switched to neutral by the user. This can reduce friction when the vehicle 200 moves on the side wall 310, and can reduce energy consumption when the transport mechanism 320 lifts and lowers the vehicle 200. Note that the vehicle 200 may be automatically controlled to activate a side brake when the transport mechanism 320 stops and parks in the parking space S, and automatically controlled to release the side brake when the transport mechanism 320 operates.

[0046] [Power supply mechanism 250] Fig. 8 is a diagram illustrating the electrical connection between the vehicle 200 and the building 300 according to this embodiment. In Fig. 8, solid arrows indicate the flow of power. Also, in Fig. 8, dashed arrows indicate the flow of signals.

[0047] As shown in Fig. 8, the solar power generation device 202 provided on the vehicle 200 includes a solar panel 204 and an inverter 206. The solar panel 204 is provided on the roof (ceiling), hood, side, etc. of the vehicle 200 body. The solar panel 204 is a solar cell that generates power by utilizing light energy from the sun 10. The solar panel 204 converts the light energy into DC power. The inverter 206 converts the DC power generated by the solar panel 204 into AC power.

[0048] The power supply mechanism 250 includes a first connection switching unit 260, a second connection switching unit 262, a first connection terminal 270, a power control unit 280, and a second connection terminal 330. In this embodiment, the first connection switching unit 260, the second connection switching unit 262, the first connection terminal 270, and the power control unit 280 are provided in the vehicle 200.

[0049] The first connection switching unit 260 switches the output destination of the inverter 206 to the battery 208 or the second connection switching unit 262. When the output destination of the inverter 206 is connected to the battery 208 by the first connection switching unit 260, the AC power converted by the inverter 206 is supplied to the battery 208.

[0050] The second connection switch 262 switches between a connection and a non-connection between the inverter 206 and the first connection terminal 270 via the first connection switch 260 .

[0051] The first connection terminal 270 is provided on the second engaged portion 220 of the vehicle 200. The first connection terminal 270 is provided so as to be connectable to the second connection terminal 330. The first connection terminal 270 supplies the AC power guided from the inverter 206 to the second connection terminal 330 via the first connection switching portion 260.

[0052] The power control unit 280 is composed of a semiconductor integrated circuit including a CPU (Central Processing Unit). The power control unit 280 reads out programs and parameters for operating the CPU itself from a ROM. The power control unit 280 manages and controls the entire power supply mechanism 250 in cooperation with a RAM as a work area and other electronic circuits.

[0053] In this embodiment, the power control unit 280 also functions as a charge amount determination unit 282 and a connection determination unit 284 .

[0054] The charge amount determination unit 282 determines whether the charge amount of the battery 208 is equal to or greater than a predetermined value (for example, fully charged). When the charge amount determination unit 282 determines that the charge amount of the battery 208 is less than the predetermined value, it controls the first connection switching unit 260 to connect the inverter 206 and the battery 208. On the other hand, when the charge amount determination unit 282 determines that the charge amount of the battery 208 is equal to or greater than the predetermined value, it controls the first connection switching unit 260 to connect the inverter 206 and the second connection switching unit 262.

[0055] The connection determination unit 284 determines whether the first connection terminal 270 and the second connection terminal 330 are connected. When the connection determination unit 284 determines that the first connection terminal 270 and the second connection terminal 330 are connected, the connection determination unit 284 controls the second connection switching unit 262 to connect the first connection switching unit 260 and the first connection terminal 270. When the connection determination unit 284 determines that the first connection terminal 270 and the second connection terminal 330 are not connected, the connection determination unit 284 controls the second connection switching unit 262 to disconnect the first connection switching unit 260 and the first connection terminal 270.

[0056] The second connection terminal 330 is provided on the second engagement portion 324 of the transport mechanism 320. The second connection terminal 330 is provided so as to be connectable to the first connection terminal 270. The second connection terminal 330 supplies AC power supplied from the first connection terminal 270 to a distribution board 350 of the building 300. In this embodiment, the second connection terminal 330 supplies power to the distribution board 350 through the movable portion 328.

[0057] The AC power supplied to the distribution board 350 is supplied to each load (air conditioner, computer, etc.) provided in the building 300. The distribution board 350 is connected to a commercial power source.

[0058] As described above, the power generation system 100 of this embodiment can supply power from the solar power generation device 202 mounted on the vehicle 200 to the building 300. Therefore, the solar power generation device 202 can avoid a situation in which power generation is stopped while the vehicle 200 is parked in the parking space S of the building 300. Therefore, the power generation system 100 can efficiently execute power generation by the solar power generation device 202.

[0059] As described above, the building 300 in this embodiment is an office building. Therefore, the power consumption in the building 300 increases with an increase in the number of people coming to work. Therefore, the power consumption during the daytime (e.g., 8:00 to 18:00) when many people come to work is higher than the power consumption during the nighttime (e.g., 18:00 to 8:00 the next day) when fewer people come to work.

[0060] Therefore, the power generation system 100 supplies power generated by solar power generation devices 202 installed in the vehicles 200 of the people going to work to the building 300. Therefore, when the number of people going to work increases, that is, when the number of parked vehicles 200 (solar power generation devices 202) increases, the power generation system 100 can increase the power supplied to the building 300. This allows the power generation system 100 to compensate for the increase in power consumption due to the increase in people going to work with the increase in the amount of power generated due to the increase in parked vehicles 200 (solar power generation devices 202).

[0061] As described above, the first connection terminal 270 is provided on the second engaged portion 220, and the second connection terminal 330 is provided on the second engaging portion 324. This allows the power generation system 100 to supply the electricity generated by the solar power generation device 202 to the building 300 by using the transport mechanism 320 without having a separate connection mechanism.

[0062] As described above, the parking space S is formed on the side wall 310 of the building 300, and the vehicle 200 is parked in the parking space S by the transport mechanism 320. This eliminates the need to provide a parking lot near the building 300.

[0063] As described above, in this embodiment, the parking space S is formed on the south sidewall 310 of the building 300. This allows the solar power generation device 202 to efficiently receive light energy from the sun 10 in the northern hemisphere. This allows the solar power generation device 202 to improve power generation efficiency. When the power generation system 100 is provided in the southern hemisphere, the parking space S is preferably formed on the north sidewall 310 of the building 300.

[0064] As described above, in this embodiment, the parking space S is formed on the inclined surface 312 of the side wall 310. This allows the solar power generation device 202 to efficiently receive light energy from the sun 10.

[0065] [Variations] 9 is a schematic cross-sectional view of a modified transport mechanism 320a. Components substantially the same as those of the transport mechanism 320 of the above embodiment are denoted by the same reference numerals and will not be described. As shown in FIG. 9, the modified transport mechanism 320a has a lifting device 400.

[0066] The lifting device 400 is provided, for example, on the ground closest to the transport mechanism 320. The lifting device 400 has a lifting section 400a that can protrude and retract from the ground, and is configured to be able to raise and lower the front section F of the vehicle 200. When the lifting section 400a protrudes from the ground, the front wheels of the vehicle 200 are lifted, and the front section F of the vehicle 200 is positioned higher than the rear section R. Specifically, when the vehicle 200 approaches within a predetermined distance of the side wall 310 (inclined surface 312) of the building 300, the lifting device 400 causes the lifting section 400a to protrude from the ground, and lifts the front section F of the vehicle 200.

[0067] According to this modification, the moment applied to the vehicle 200 when the first engagement portion 322 lifts the front portion F of the vehicle 200 can be reduced by the amount that the lifting / lowering portion 400a lifts the front portion F of the vehicle 200. Note that, in this modification, the same actions and effects as those of the above embodiment can be obtained.

[0068] Although the preferred embodiment of the present invention has been described above with reference to the accompanying drawings, it goes without saying that the present invention is not limited to such an embodiment. It is clear that a person skilled in the art can think of various modifications or alterations within the scope of the claims, and it is understood that these also naturally belong to the technical scope of the present invention.

[0069] In the above embodiment, the parking space S is formed on the south side wall 310 of the building 300. However, the parking space S may be provided on the east side wall, the south side wall 310, or the west side wall of the building 300. In this case, the multiple vehicles 200 are first parked in the parking space S formed on the east side wall. Then, when the parking space S formed on the east side wall becomes full, the vehicles are parked in the parking space S formed on the south side wall 310. When the parking space S formed on the south side wall 310 becomes full, the vehicles are parked in the parking space S formed on the west side wall. The parking space S may also be formed on the ceiling of the building 300.

[0070] In the above embodiment, the side wall 310 of the building 300 is a flat surface. However, the side wall 310 may be a curved surface.

[0071] Moreover, the parking space S may be provided near the building 300. In either case, in the power generation system 100, the parking space S functions as a power farm.

[0072] In the above embodiment, the first connection terminal 270 is provided on the second engaged portion 220 of the vehicle 200, and the second connection terminal 330 is provided on the second engaging portion 324 of the transport mechanism 320. However, the first connection terminal 270 may be provided on the first engaged portion 210 of the vehicle 200, and the second connection terminal 330 may be provided on the first engaging portion 322 of the transport mechanism 320. Similarly, the first connection terminal 270 may be provided on the third engaged portion 230 of the vehicle 200, and the second connection terminal 330 may be provided on the third engaging portion 326 of the transport mechanism 320. The vehicle 200 may also be provided with the first connection terminal 270 at a location other than the first engaged portion 210, the second engaged portion 220, and the third engaged portion 230. In this case, the building 300 has the second connection terminal 330 that is detachably provided with the first connection terminal 270 of the vehicle 200.

[0073] In the above embodiment, the connection determination unit 284 is provided in the vehicle 200. However, the connection determination unit 284 may be provided in the building 300 (the transport mechanism 320).

[0074] In the above embodiment, the solar power generation device 202 and the distribution board 350 are connected by wire. However, the solar power generation device 202 may supply power to the distribution board 350 in a non-contact manner.

[0075] In the above embodiment and modified example, the vehicle 200 includes the first engaged portion 210, and the transport mechanisms 320, 320a include the first engaging portion 322. However, this is not limiting, and the vehicle 200 does not have to include the first engaged portion 210. In addition, the transport mechanisms 320, 320a do not have to include the first engaging portion 322.

[0076] In the above embodiment and modified example, the first engagement portion 322, the second engagement portion 324, and the third engagement portion 326 have the inclined portions 322b, 324b. However, this is not limited thereto, and the first engagement portion 322, the second engagement portion 324, and the third engagement portion 326 do not necessarily have to have the inclined portions 322b, 324b.

[0077] In the above modified example, an example has been described in which the transport mechanism 320a includes the first engaging portion 322 in addition to the lifting device 400. However, the present invention is not limited to this, and the transport mechanism 320a of the modified example may not include the first engaging portion 322 as long as it includes the lifting device 400. In this case, the vehicle 200 does not need to include the first engaged portion 210, and the cost of the vehicle 200 can be reduced. In addition, the lifting device 400 may be provided in the vehicle 200, not in the transport mechanism 320a (ground). [Explanation of symbols]
