[0003] [Patent Document 1] JP 2011-243921 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, the lower area of ​​the light receiving area (solar panel) is not effectively utilized.

[0005] Therefore, an object of the present invention is to provide a vehicle that can effectively utilize the lower area of ​​the light receiving area. etc. The purpose of this project is to provide [Means for solving the problem]

[0006] The vehicle of the present invention comprises a first power generating device having a first left light receiving area, a central light receiving area, a first right light receiving area, a first front light receiving area, and a first rear light receiving area for generating solar power, a first holding device for holding the first power generating device, and a vehicle body for holding the first holding device on its upper surface. The first holding device holds the first left light receiving area in a state where it can be moved leftward from the first reference position, holds the central light receiving area in a state where it is fixed at the first reference position, holds the first right light receiving area in a state where it can be moved rightward from the first reference position, holds the first front light receiving area in a state where it can be moved forward from the first reference position, and holds the first rear light receiving area in a state where it can be moved rearward from the first reference position. The first holding device is capable of holding the first left light receiving area, the central light receiving area, the first right light receiving area, the first front light receiving area and the first rear light receiving area in a first closed state in which they are stacked at a first reference position. The first holding device is capable of holding the first left light receiving area, the central light receiving area, the first right light receiving area, the first front light receiving area, and the first rear light receiving area in a first open state in which they do not overlap when viewed from above.

[0007] The upper area of ​​the vehicle is covered by a plurality of light receiving areas (such as a central light receiving area). This prevents the lower areas of the plurality of light receiving areas (such as an area inside the vehicle) from becoming too hot due to direct sunlight, and prevents deterioration of electrical equipment related to the light receiving areas, such as a power storage device. In addition, a shaded area can be formed around the vehicle. This makes it possible to effectively utilize the lower areas of the plurality of light receiving areas.

[0008] The first holding device holds the five light receiving areas (such as the first left light receiving area) of the first power generating device in a stacked manner in a first reference position (first closed state). In addition, the first holding device holds the five light receiving areas of the first power generating device in a position where four of the five light receiving areas of the first power generating device are shifted laterally from the first reference position and do not overlap when viewed from above (first open state). This provides a light receiving area equivalent to five solar panels, making it possible to obtain a large amount of power from sunlight.

[0009] Preferably, the first power generating device further includes a second front light-receiving region and a second rear light-receiving region. The first holding device holds the second front light receiving region in a state where it can be moved forward from the first reference position relative to the first front light receiving region, and holds the second rear light receiving region in a state where it can be moved rearward from the first reference position relative to the first rear light receiving region.

In addition, the first holding device holds the seven light receiving areas of the first power generating device in a position where six of the seven light receiving areas of the first power generating device are shifted laterally from the first reference position and do not overlap when viewed from above (first open state). This provides a light receiving area equivalent to seven photovoltaic panels, making it possible to obtain a large amount of power from sunlight.

[0011] More preferably, the vehicle further includes a first base portion provided on an upper surface of the vehicle body. The first base portion holds the first holding device on an upper surface of the first base portion. The first base portion has a first angle adjustment portion that adjusts the degree of inclination of the upper surface of the first base portion.

The vehicle body holds the second base portion on a side thereof and holds the third base portion on a side opposite the side thereof. The second base portion is rotatably movable at least so that the upper surface of the second base portion faces upward and to the left. The third base portion is capable of rotational movement at least so that the top surface of the third base portion faces upward and to the right. When the upper surface of the second base portion faces upward, the second holding device holds the second left light receiving area in a state in which it can be moved leftward from the second reference position, holds the third front light receiving area in a state in which it can be moved forward from the second reference position, and holds the third rear light receiving area in a state in which it can be moved rearward from the second reference position. When the upper surface of the third base portion faces upward, the third holding device holds the second right light receiving area in a state where it can be moved to the right from the third reference position, holds the fourth front light receiving area in a state where it can be moved forward from the third reference position, and holds the fourth rear light receiving area in a state where it can be moved rearward from the third reference position. The second holding device is capable of holding the second left light receiving area, the third front light receiving area and the third rear light receiving area in a second closed state in which they are stacked vertically at a second reference position when the upper surface of the second base portion faces upward. The second holding device is capable of holding the second left light receiving area, the third front light receiving area and the third rear light receiving area in a third closed state in which they are stacked horizontally at the second reference position when the upper surface of the second base portion faces left.

The third holding device is capable of holding the second right light receiving area, the fourth front light receiving area and the fourth rear light receiving area in a fourth closed state in which they are stacked vertically at the third reference position when the upper surface of the third base portion faces upward. The third holding device is capable of holding the second right light receiving area, the fourth front light receiving area and the fourth rear light receiving area in a fifth closed state in which they are stacked horizontally at the third reference position when the upper surface of the third base portion faces to the right. The third holding device is capable of holding the second right light receiving area, the fourth front light receiving area, and the fourth rear light receiving area in a third open state in which they do not overlap when viewed from above when the upper surface of the third base portion faces upward.

[0013] The second holding device holds the three light receiving areas (such as the second left light receiving area) of the second power generating device in a stacked manner in a second reference position (second closed state, third closed state). In addition, the second holding device holds the three light receiving areas of the second power generating device in a position where the three light receiving areas are shifted laterally and do not overlap when viewed from above (second open state). This provides a light receiving area equivalent to three solar panels, making it possible to obtain a large amount of power from sunlight.

[0014] The third holding device holds the three light receiving areas (such as the second right light receiving area) of the third power generating device in a stacked manner in a third reference position (fourth closed state, fifth closed state). In addition, the third holding device holds the three light receiving areas of the third power generating device in a position where the three light receiving areas are shifted laterally and do not overlap when viewed from above (third open state). This provides a light receiving area equivalent to three solar panels, making it possible to obtain a large amount of power from sunlight.

[0015] More preferably, when the first holding device holds the first power generation device in the first open state and the second holding device holds the second power generation device in the second closed state, the first left light receiving area is positioned so as to overlap the second left light receiving area, the third front light receiving area, and the third rear light receiving area when viewed from above. When the first holding device holds the first power generation device in the first open state and the second holding device holds the second power generation device in the second open state, the first left light receiving area is in a positional relationship that does not overlap with the second left light receiving area, the third front light receiving area, and the third rear light receiving area, when viewed from above. When the first holding device maintains the first power generation device in the first open state and the third holding device holds the third power generation device in the fourth closed state, when viewed from above, the first right light receiving area is positioned so as to overlap the second right light receiving area, the fourth front light receiving area, and the fourth rear light receiving area. When the first holding device maintains the first power generation device in the first open state and the third holding device holds the third power generation device in the third open state, the first right light receiving area is in a position that does not overlap with the second right light receiving area, the fourth front light receiving area, and the fourth rear light receiving area when viewed from above.

[0016] (Effect of preventing physical interference between the first power generation device 11a, the second power generation device 11b, and the third power generation device 11c) The first holding device holds the light receiving area of ​​the first power generating device in a positional relationship such that the light receiving area of ​​the first power generating device in the first open state does not overlap with the light receiving area of ​​the second power generating device in the second open state, and the light receiving area of ​​the third power generating device in the third open state, when viewed from above. This makes it possible to efficiently arrange the light receiving areas of the first power generation device, the second power generation device, and the third power generation device in a space including the area above the vehicle, thereby making it possible to obtain a large amount of electricity from sunlight.

[0017] More preferably, when the second holding device holds the second power generating unit in the third closed state, the second base portion is housed in a recessed portion provided in the left side surface of the vehicle body. When the third holding device holds the third power generation unit in the fifth closed state, the third base portion is housed in a recessed portion provided in the right side surface of the vehicle body.

[0018] At least a portion of the second power generating unit is housed in a recessed portion on the left side surface of the vehicle body (third closed state). At least a portion of the third power generating unit is housed in a recessed portion on the right side surface of the vehicle body (fifth closed state). Therefore, it is possible to reduce the height dimension of the vehicle compared to a configuration in which the second power generation device and the third power generation device are stacked on the first power generation device. Also, compared to a configuration in which a second power generating unit and the like are disposed on the side surface without providing a recess, it is possible to reduce the dimension in the width direction of the vehicle.

[0019] Also, preferably, the first holding device holds the underside of the first left light receiving area in a state where it is movable leftward from the first reference position and the inclination of the first left light receiving area is adjustable, holds the underside of the first right light receiving area in a state where it is movable rightward from the first reference position and the inclination of the first right light receiving area is adjustable, holds the underside of the first front light receiving area in a state where it is movable forward from the first reference position and the inclination of the first front light receiving area is adjustable, and holds the underside of the first rear light receiving area in a state where it is movable rearward from the first reference position and the inclination of the first rear light receiving area is adjustable. When the upper surface of the second base portion faces upward, the second holding device holds the lower surface of the second left light receiving area in a state in which it is movable leftward from the second reference position and the inclination of the second left light receiving area is adjustable, holds the lower surface of the third front light receiving area in a state in which it is movable forward from the second reference position and the inclination of the third front light receiving area is adjustable, and holds the lower surface of the third rear light receiving area in a state in which it is movable rearward from the second reference position and the inclination of the third rear light receiving area is adjustable.

[0020] By having the holding region hold the lower surface of the light receiving region, the number of connection points between the holding region and the light receiving region is reduced compared to a configuration in which the side surfaces of the light receiving region are held, and the structure can be simplified.

[0021] Also, preferably, the first holding device holds the first front light-receiving region and the second front light-receiving region at a position higher than the first rear light-receiving region and the second rear light-receiving region. The second holding device holds the third rear light-receiving region at a higher position than the third front light-receiving region. The third holding device holds the fourth rear light-receiving region at a higher position than the fourth front light-receiving region.

The electric power stored in the first power storage device can be supplied to an external device.

[0025] The first power generating device, the second power generating device, and the third power generating device have a larger light receiving surface area than the solar panels mounted on the roof of a normal vehicle, which makes it possible to store the electricity required for a longer period of driving in a storage device, etc., compared to the normal vehicle.

[0026] In addition, preferably, the first holding device holds the lower surface of the first left light receiving area in a state in which it can be moved leftward from the first reference position, holds the lower surface of the first right light receiving area in a state in which it can be moved rightward from the first reference position, holds the lower surface of the first front light receiving area in a state in which it can be moved forward from the first reference position, and holds the lower surface of the first rear light receiving area in a state in which it can be moved rearward from the first reference position.

On the upper surface 2a of the luggage compartment formed in a substantially rectangular parallelepiped shape of the vehicle body 2, a first power generation device 11a, a first base portion 12a, and a first holding device 13a of the first power generation unit 11 described later are provided. On the left side surface of the luggage compartment of the vehicle body 2, a region recessed in the x direction (a first side surface recess 2b) is formed, and a second power generation device 11b, a second base portion 12b, and a second holding device 13b of the first power generation unit 11 described later are provided in the first side surface recess 2b. On the right side surface of the luggage compartment of the vehicle body 2, a region recessed in the x direction (a second side surface recess 2c (not shown)) is formed, and a third power generation device 11c, a third base portion 12c, and a third holding device 13c of the first power generation unit 11 described later are provided in the second side surface recess 2c.

[0037] (Control unit 5) The control unit 5 controls the electrical equipment of the vehicle 1. Specifically, the control unit 5 controls the operations of the first base portion 12a, the second base portion 12b, the third base portion 12c, the first holding device 13a, the second holding device 13b, and the third holding device 13c.

[0038] For example, when the state of charge R1 of the first power storage device 21 is lower than the first charge rate threshold Thr1 (R1 < Thr1, for example, Thr1 = 60%) and power supply from the first power storage device 21 to the second power storage device 22 is not being performed, the control unit 5 accumulates power in the first power storage device 21 based on the power obtained by the first power generation unit 11.

[0039] Further, when the charging rate R1 of the first power storage device 21 is lower than the second charging rate threshold value Thr2 (Thr2 < Thr1, for example, Thr2 = 40%), the charging rate R2 of the second power storage device 22 is lower than the second charging rate threshold value Thr2, and there is no power supply from the external power supply A100 via the second conversion device 42, the control unit 5 drives the second power generation device 12 (R1 < Thr2, R2 < Thr2).

[0040] (Input / output control of the second conversion device 42) Further, the control unit 5 performs input / output control of the second conversion device 42. Specifically, when performing power supply from the first power storage device 21 to the second power storage device 22, the control unit 5 cuts off the input (power supply) from the second power generation device 12 to the second conversion device 42 and the input (power supply) from the external power supply A100 to the second conversion device 42. When performing power supply from the second power generation device 12 to the second power storage device 22, the control unit 5 cuts off the input (power supply) from the first power storage device 21 to the second conversion device 42 and the input (power supply) from the external power supply A100 to the second conversion device 42. When performing power supply from the first power storage device 21 to the second power storage device 22 and power supply from the second power generation device 12 to the second power storage device 22, the control unit 5 cuts off the input (power supply) from the external power supply A100 to the second conversion device 42. When performing power supply from the external power supply A100 to the second power storage device 22, the control unit 5 cuts off the input (power supply) from the first power storage device 21 to the second conversion device 42 and the input (power supply) from the second power generation device 12 to the second conversion device 42.

[0041] (Power supply cutoff control to the second power storage device 22) However, while the second power storage device 22 is discharging, such as during traveling, that is, at least when the second power storage device 22 drives the motor 50, the control unit 5 cuts off the output (power supply) from the second conversion device 42 to the second power storage device 22.

[0042] The cutoff control of the output (power supply) from the second conversion device 42 to the second power storage device 22 may be performed not only while the vehicle 1 is traveling, but also while an accessory switch of the vehicle 1 is in the on state.

[0043] (Location information acquisition unit 7) The location information acquisition unit 7 acquires information about the location of the vehicle 1 from base stations of communication devices such as mobile phones, satellites, and the like. The position information acquisition unit 7 has a gyro sensor, an acceleration sensor, etc., and acquires information related to the orientation of the vehicle 1. Based on the position information and orientation information obtained by the position information acquisition unit 7, the control unit 5 adjusts the angle (inclination degree) of the solar panel such as the eleventh light receiving region 11a1.

[0044] (First power generation section 11) The first power generation section 11 is a solar power generation device. The first power generating section 11 is always in a state in which it is capable of generating power. The electric power obtained in the first power generating unit 11 is supplied to the first power storage device 21 under the control of the control unit 5.

[0045] The first power generation section 11 has a first power generation device 11a, a second power generation device 11b, a third power generation device 11c, a first base portion 12a, a second base portion 12b, a third base portion 12c, a first holding device 13a, a second holding device 13b, and a third holding device 13c.

[0046] (First power generating unit 11a) The first power generating device 11a has an eleventh light receiving region 11a1, a twelfth light receiving region 11a2, a thirteenth light receiving region 11a3, a fourteenth light receiving region 11a4, a fifteenth light receiving region 11a5, a sixteenth light receiving region 11a6, and a seventeenth light receiving region 11a7. The eleventh light-receiving region 11a1, the twelfth light-receiving region 11a2, the thirteenth light-receiving region 11a3, the fourteenth light-receiving region 11a4, the fifteenth light-receiving region 11a5, the sixteenth light-receiving region 11a6, and the seventeenth light-receiving region 11a7 each have a solar panel for generating solar power.

[0047] (First base portion 12a) The first base portion 12a is provided on an upper surface 2a of the luggage compartment of the vehicle body 2. The first base portion 12a holds the first power generating device 11a and the first holding device 13a on the upper surface of the first base portion 12a. The first base portion 12a includes a first angle adjustment portion 12a1 that adjusts the angle between an upper surface of the first base portion 12a (the surface in contact with the first retaining device 13a) and an upper surface 2a of the luggage compartment of the vehicle body 2. When not in use and during opening and closing operations, the first angle adjustment portion 12a1 makes the upper surface of the first base portion 12a parallel to the upper surface 2a of the luggage compartment of the vehicle main body 2 (see Figs. 2 to 5). During use, first angle adjustment portion 12a1 raises the right side or the left side in the x direction of the top surface of first base portion 12a (see FIG. 6). It is desirable to adjust the degree of elevation of the top surface of the first base portion 12a on the right side in the x-direction or the left side in the x-direction (the degree of inclination of the top surface of the first base portion 12a) so that when the light receiving surface such as the eleventh light receiving area 11a1 faces south and the sun is at its highest point, the angle of incidence of sunlight (the angle between the angle of incidence and the normal to the light receiving surface of the eleventh light receiving area 11a1) becomes small, in other words, the angle between the angle of incidence of sunlight and the light receiving surface of the eleventh light receiving area 11a1 becomes close to vertical. For this reason, it is desirable to adjust the degree of inclination of the upper surface of first base portion 12a based on the position information and orientation information obtained by position information acquisition unit . First angle adjustment portion 12a1 moves the upper surface of first base portion 12a electrically based on a control signal from control portion 5, or manually by the user.

[0050] That is, when not in use, the first holding device 13a holds the first power generation device 11a so that the 11th light receiving area 11a1, the 12th light receiving area 11a2, the 13th light receiving area 11a3, the 14th light receiving area 11a4, the 15th light receiving area 11a5, the 16th light receiving area 11a6, and the 17th light receiving area 11a7 overlap in the z direction (see Figures 2 and 3, first closed state).

[0051] During use, the first holding device 13a holds the first power generating device 11a in a state in which the eleventh light receiving area 11a1, the twelfth light receiving area 11a2, the thirteenth light receiving area 11a3, the fourteenth light receiving area 11a4, the fifteenth light receiving area 11a5, the sixteenth light receiving area 11a6, and the seventeenth light receiving area 11a7 do not overlap in the normal direction of the upper surface of the first base portion 12a, and the first power generating device 11a and the first holding device 13a are arranged to form approximately a cross when viewed in the normal direction of the upper surface of the first base portion 12a (see Figures 4 to 6, first open state).

[0052] (11th holding area 13a1) The eleventh holding region 13a1 is an area on the left side of the first reference position P1 and holds the eleventh light receiving region 11a1 in a state in which it can move in the x direction.

At this time, the eleventh light receiving region 11a1 is located above the second base portion 12b. Therefore, when the second holding device 13b holds the twenty-first light receiving region 11b1 and the like in the second closed state, the eleventh light receiving region 11a1 overlaps with the twenty-first light receiving region 11b1, the twenty-second light receiving region 11b2, and the twenty-third light receiving region 11b3 when viewed from the normal direction of the upper surface of the first base portion 12a. However, when the second holding device 13b holds the twenty-first light receiving region 11b1 and the like in the second open state, the eleventh light receiving region 11a1 does not overlap with the twenty-first light receiving region 11b1, the twenty-second light receiving region 11b2, and the twenty-third light receiving region 11b3 that are arranged in the use position when viewed from the normal direction of the upper surface of the first base portion 12a.

[0056] The eleventh holding region 13a1 moves the eleventh light receiving region 11a1 electrically based on a control signal from the control unit 5, or manually by the user.

[0086] During use, second angle adjustment portion 12b1 raises or lowers the left side in the x direction of the upper surface of second base portion 12b (see FIG. 6). It is desirable to adjust the degree of ascent or descent of the left side in the x-direction of the upper surface of the second base portion 12b (the degree of inclination of the upper surface of the second base portion 12b) so that when the light receiving surface such as the 21st light receiving area 11b1 faces south and the sun is at its highest point, the angle of incidence of sunlight (the angle between the angle of incidence and the normal to the light receiving surface of the 21st light receiving area 11b1) becomes small, in other words, so that the angle between the angle of incidence of sunlight and the light receiving surface of the 21st light receiving area 11b1 becomes close to perpendicular. For this reason, it is desirable to adjust the degree of inclination of the upper surface of second base portion 12b based on the position information and orientation information obtained by position information acquisition unit . Second angle adjustment portion 12b1 moves the upper surface of second base portion 12b electrically based on a control signal from control portion 5, or manually by the user.

[0102] (23rd holding area 13b3) When the upper surface of the second base portion 12b faces upward in the z direction, the 23rd holding area 13b3 is located below the 22nd holding area 13b2, and holds the 23rd light receiving area 11b3 in a state where it can move in the y direction in the area forward of the second reference position P2.

[0103] The 23rd holding region 13b3 includes an elastic member, such as a slide rail, that holds the side surface of the 23rd light receiving region 11b3 perpendicular to the x direction while being movable in the y direction when the upper surface of the second base portion 12b faces upward in the z direction.

[0108] (Third base portion 12c) The third base portion 12c is provided in a second side recess 2c (not shown) on the right side of the luggage compartment of the vehicle body 2. The third base portion 12c holds the third power generating device 11c and the third holding device 13c on the upper surface of the third base portion 12c. The third base portion 12c includes a third angle adjustment portion 12c1 that adjusts the angle between an upper surface of the third base portion 12c (the surface in contact with the third holding device 13c) and an upper surface 2a of the luggage compartment of the vehicle body 2. When not in use, the third angle adjustment portion 12c1 aligns the upper surface of the third base portion 12c perpendicular to the upper surface 2a of the luggage compartment of the vehicle main body 2, i.e., parallel to the side of the luggage compartment of the vehicle main body 2, so that the third base portion 12c is stored in the second side recess portion 2c (fifth closed state). During opening and closing operations, third angle adjustment portion 12c1 makes the upper surface of third base portion 12c parallel to upper surface 2a of the luggage compartment of vehicle body 2 (see FIGS. 3 to 5, fourth closed state or third open state). In other words, third angle adjustment portion 12c1 enables third base portion 12c to rotate about an axis parallel to the y direction so that the top surface of third base portion 12c is at least in a state in which it faces upward (perpendicular to the z direction), a state in which it faces to the right in the x direction (perpendicular to the x direction), or a state inclined.

[0109] During use, third angle adjustment portion 12c1 raises or lowers the right side in the x-direction of the upper surface of third base portion 12c (see FIG. 6). It is desirable to adjust the degree of ascent or descent of the top surface of the third base portion 12c on the right side in the x-direction (the degree of inclination of the top surface of the third base portion 12c) so that when the light receiving surface such as the 31st light receiving area 11c1 faces south and the sun is at its highest point, the angle of incidence of sunlight (the angle between the angle of incidence and the normal to the light receiving surface of the 31st light receiving area 11c1) becomes small, in other words, so that the angle between the angle of incidence of sunlight and the light receiving surface of the 31st light receiving area 11c1 becomes close to vertical. For this reason, it is desirable to adjust the degree of inclination of the upper surface of the third base portion 12c based on the position information and orientation information obtained by the position information acquisition unit . Third angle adjustment portion 12c1 moves the upper surface of third base portion 12c electrically based on a control signal from control portion 5, or manually by the user.

[0110] It is preferable that a third leg portion 12c2 is provided on the lower surface of the third base portion 12c. The third leg 12c2 is configured as a telescopic leg that is extendable and contractible in the z direction. During opening / closing operations and during use, the third leg portion 12c2 extends and comes into contact with the ground to support the third base portion 12c. When not in use, the third leg portion 12c2 is retracted and stored in the second side recess portion 2c. When not in use, the third leg 12c2 may be stored in a state where it is bent from a state where it extends in the z direction to a state where it extends in the x direction or y direction. The third leg 12c2 extends and retracts electrically based on a control signal from the control unit 5, or manually by the user.

[0111] (Third holding device 13c) The third holding device 13c has a 31st holding area 13c1, a 32nd holding area 13c2, and a 33rd holding area 13c3.

In addition, when the upper surface of the third base portion 12c faces to the right in the y direction, the third holding device 13c can hold the 31st light receiving area 11c1, the 32nd light receiving area 11c2, and the 33rd light receiving area 11c3 in a fifth closed state stacked in the y direction at the third reference position P3 (see Figure 2). In addition, when the upper surface of the third base portion 12c faces upward in the z direction, the third holding device 13c can hold the 31st light receiving area 11c1, the 32nd light receiving area 11c2, and the 33rd light receiving area 11c3 in a third open state in which they do not overlap when viewed from above (when viewed from the normal direction to the upper surface of the third base portion 12c) (see Figures 5 and 6).

[0113] When not in use, the third holding device 13c holds the third power generation device 11c so that the 31st light receiving area 11c1, the 32nd light receiving area 11c2, and the 33rd light receiving area 11c3 overlap in the normal direction to the upper surface of the third base portion 12c (see Figures 2 and 3, fifth closed state or fourth closed state).

[0114] When in use, the third holding device 13c holds the third power generation device 11c in a state in which the 31st light receiving area 11c1, the 32nd light receiving area 11c2, and the 33rd light receiving area 11c3 do not overlap in the normal direction of the upper surface of the third base portion 12c, and the third power generation device 11c and the third holding device 13c are arranged to form approximately a T shape when viewed in the normal direction of the upper surface of the third base portion 12c (see Figures 4 to 6, third open state).

[0115] (31st holding area 13c1) The 31st holding region 13c1 holds the 31st light receiving region 11c1 in a state in which it can move in the x direction in a region to the right of the third reference position P3 when the top surface of the third base portion 12c faces upward in the z direction.

[0116] The 31st holding region 13c1 includes an elastic member, such as a slide rail, that holds the side surface perpendicular to the y direction of the 31st light receiving region 11c1 while being movable in the x direction when the upper surface of the third base portion 12c faces upward in the z direction.

[0117] When not in use, the third holding region 13c1 holds the third light receiving region 11c1 with the elastic member of the third holding region 13c1 contracted (see Figs. 2 and 3, fifth closed state or fourth closed state).

[0118] During use, the third holding region 13c1 holds the third light receiving region 11c1 with the extensible member of the third holding region 13c1 stretched to the right in the x direction (see FIGS. 4 to 6, third open state).

[0119] The 31st holding region 13c1 moves the 31st light receiving region 11c1 electrically based on a control signal from the control unit 5, or manually by the user.

[0120] (32nd holding area 13c2) When the upper surface of the third base portion 12c faces upward in the z direction, the 32nd holding area 13c2 is located below the 31st holding area 13c1 and holds the 32nd light receiving area 11c2 in a state that is movable in the y direction in an area rear of the third reference position P3.

[0121] The 32nd holding region 13c2 includes an elastic member, such as a slide rail, that holds the side surface of the 32nd light receiving region 11c2 perpendicular to the x direction while being movable in the y direction when the upper surface of the third base portion 12c faces upward in the z direction.

[0122] When not in use, the third holding region 13c2 holds the third light receiving region 11c2 with the elastic member of the third holding region 13c2 contracted (see FIGS. 2 and 3, the fifth closed state or the fourth closed state).

[0123] During use, the third holding region 13c2 holds the third light receiving region 11c2 with the elastic member of the third holding region 13c2 stretched rearward in the y direction (see FIGS. 4 to 6, third open state).

[0124] The 32nd holding region 13c2 moves the 32nd light receiving region 11c2 electrically based on a control signal from the control unit 5, or manually by the user.

[0125] (33rd holding area 13c3) When the upper surface of the third base portion 12c faces upward in the z direction, the 33rd holding area 13c3 is located below the 32nd holding area 13c2, and holds the 33rd light receiving area 11c3 in a state that is movable in the y direction in the area forward of the third reference position P3.

[0126] The 33rd holding region 13c3 includes an elastic member, such as a slide rail, that holds the side surface of the 33rd light receiving region 11c3 perpendicular to the x direction while being movable in the y direction when the top surface of the third base portion 12c faces upward in the z direction.

[0127] When not in use, the third holding region 13c3 holds the third light receiving region 11c3 with the elastic member of the third holding region 13c3 contracted (see FIGS. 2 and 3, the fifth closed state or the fourth closed state).

[0128] During use, the third holding region 13c3 holds the third light receiving region 11c3 with the elastic member of the third holding region 13c3 stretched forward in the y direction (see FIGS. 4 to 6, third open state).

[0129] The 33rd holding region 13c3 moves the 33rd light receiving region 11c3 electrically based on a control signal from the control unit 5, or manually by the user.

[0130] (Size of light receiving area) The total area (light receiving area) of the light receiving surfaces of the seven light receiving areas (11th light receiving area 11a1 to 17th light receiving area 11a7) of the first power generating device 11a, the three light receiving areas (21st light receiving area 11b1 to 23rd light receiving area 11b3) of the second power generating device 11b, and the three light receiving areas (31st light receiving area 11c1 to 33rd light receiving area 11c3) of the third power generating device 11c are configured to be larger than the upper area of ​​the vehicle 1, such as the top surface 2a of the luggage compartment of the vehicle body 2.

[0131] (Second power generation section 14) The second power generation section 14 is a power generation device other than a solar power generation device, such as a fuel cell. The second power generation unit 14 is set to a state in which power generation is possible when the state of charge of the second power storage device 22 is not sufficient (when the charging rate R2 of the second power storage device 22 is lower than the second charging rate threshold Thr2), etc. The second power generating section 14 is disposed inside the vehicle body 2 or the like. The electric power obtained in the second power generating unit 14 is supplied to the second power storage device 22 via the second conversion device 42 under the control of the control unit 5.

[0132] (Electricity storage unit 20) The power storage unit 20 includes a first power storage device 21 and a second power storage device 22 .

[0133] (First power storage device 21) The first power storage device 21 is configured by a battery or the like, and stores the power generated by the first power generation section 11. The first power storage device 21 is used to temporarily store electric power before charging the second power storage device 22, for example, while the vehicle is traveling. The first power storage device 21 may be used to drive electrical devices constituting the vehicle 1, such as the control unit 5. The first power storage device 21 may also be used to supply power to the external device A200. In addition, when vehicle 1 includes an internal combustion engine such as an engine in addition to motor 50 to rotate wheels 60, power storage unit 20 may have a starting battery in addition to first power storage device 21 and second power storage device 22. The first power storage device 21 may be composed of one power storage device or may be composed of multiple power storage devices. When the first power storage device 21 is composed of multiple power storage devices, the capacity of each power storage device can be made smaller than when the first power storage device 21 is composed of one power storage device.

[0134] The first power storage device 21 may be used to store the power obtained by the second power generation unit 14 and the power supplied from the external power supply A100. For example, when the charging rate R1 of the first storage device 21 is lower than the second charging rate threshold Thr2 and the charging rate of the second storage device 22 is higher than or equal to the first charging rate threshold Thr1, the electric power obtained by the second power generation unit 14 is supplied to the first storage device 21 via the second conversion device 42 (R1 <Thr2、R2≧Thr1)。

[0135] (Second power storage device 22) The second power storage device 22 is formed of a battery or the like, and is used to drive the motor 50, that is, to supply electric power to the motor 50. The second power storage device 22 stores the power stored in the first power storage device 21, the power obtained by the second power generation unit 14, and the power supplied from the external power source A100.

[0136] (Conversion unit 40) The conversion unit 40 includes a first conversion device 41 and a second conversion device 42 .

[0137] (First conversion device 41) The first conversion device 41 is a charging device including a power conditioner, a DC / DC converter, and the like. The first conversion device 41 converts the electric power obtained in the first power generation section 11 into a current and voltage suitable for charging the first power storage device 21, and supplies the converted electric power to the first power storage device 21. Moreover, the first conversion device 41 supplies the electric power from the first power storage device 21 to the electric devices constituting the vehicle 1, such as the control unit 5.

[0138] (Second conversion device 42) The second conversion device 42 converts the power from an external power supply device (external power source A100) external to the vehicle 1, such as a commercial power source, from AC to DC, and also converts it into a current and voltage suitable for charging the second storage device 22, and supplies it to the second storage device 22. Further, the second conversion device 42 converts the electric power from the first power storage device 21 into a current and voltage suitable for charging the second power storage device 22, and supplies the converted electric power to the second power storage device 22. Further, the second conversion device 42 converts the electric power from the second power generation device 12 into a current and voltage suitable for charging the second power storage device 22, and supplies the converted electric power to the second power storage device 22. In addition, the second conversion device 42 converts the power from the first storage device 21 from direct current to alternating current, and also converts it into a desired current and voltage, and supplies it to an electrical device (external device A200) outside the vehicle 1, such as an electrical device installed in a building.

[0139] (Quick charging device) The second conversion device 42 may include a quick charger that supplies power from the external power source A100 to the first power storage device 21 or the second power storage device 22 with at least one of the voltage and the current increased. The second conversion device 42 may also include a quick charger that supplies power from the first power storage device 21 to the external device A200 with at least one of the voltage and the current increased.

[0140] (Motor 50, Wheels 60) The motor 50 is driven based on the electric power from the second power storage device 22 to rotate the wheels 60 of the vehicle 1 . The wheels 60 of the vehicle 1 are not limited to those driven by the motor 50, and may be those driven by an internal combustion engine such as an engine. In the case where the vehicle 1 does not use the motor 50 and is driven only by an internal combustion engine, the second electric storage device 22 and the motor 50 may be omitted.

[0141] (Effect of providing multiple light receiving areas above the vehicle 1) The upper area of ​​the vehicle 1 is covered by a plurality of light receiving areas (such as the eleventh light receiving area 11a1). This prevents the lower areas of the plurality of light receiving areas (such as the area inside the vehicle 1) from becoming too hot due to direct sunlight, and can prevent deterioration of electrical equipment related to the light receiving areas, such as the first power storage device 21. In addition, a shaded area can be formed around the vehicle 1. This makes it possible to effectively utilize the lower areas of the plurality of light receiving areas.

[0142] (Effect of utilizing the top and sides of vehicle 1) Further, the members constituting the first power generating unit 11, such as the first base portion 12a, are provided on the top surface 2a, left side surface, and right side surface of the vehicle body 2, but not on the back surface (the area where the rear door in the y direction is located). This makes it possible to generate electricity without interfering with tasks such as loading and unloading luggage on the vehicle 1.

[0143] (Effect of using multiple light receiving areas) When not in use, the first holding device 13a holds the seven light receiving areas (the eleventh light receiving area 11a1 to the seventeenth light receiving area 11a7) of the first power generating device 11a in a stacked manner in the z direction at the first reference position P1 (first closed state). During use, the first holding device 13a holds the seven light receiving areas of the first power generating device 11a in a positional relationship in which six of the seven light receiving areas of the first power generating device 11a are shifted in the x or y direction from the first reference position P1 and do not overlap when viewed from the normal direction of the top surface of the first base portion 12a (first open state). This ensures seven times the light-receiving area compared to when the solar panel is not in use, making it possible to obtain more electricity from sunlight.

[0144] When not in use, the second holding device 13b holds the three light receiving areas (the 21st light receiving area 11b1 to the 23rd light receiving area 11b3) of the second power generating device 11b in a stacked manner in the normal direction to the upper surface of the second base portion 12b at the second reference position P2. Specifically, when the second base portion 12b is stored in the first side recess portion 2b, that is, when the upper surface of the second base portion 12b is perpendicular to the y direction, the second holding device 13b holds the three light receiving areas of the second power generation device 11b stacked in the y direction (third closed state). When the top surface of the second base portion 12b is perpendicular to the z direction, the second holding device 13b holds the three light receiving regions of the second power generating device 11b stacked in the z direction (second closed state). When in use, the second holding device 13b holds the three light receiving areas of the second power generation device 11b in a positional relationship in which the three light receiving areas are shifted in the x or y direction and do not overlap when viewed from the normal direction of the top surface of the second base portion 12b (second open state). This ensures three times the light receiving area compared to when not in use, making it possible to obtain more power from sunlight.

[0145] When not in use, the third holding device 13c holds the three light receiving areas (the 31st light receiving area 11c1 to the 33rd light receiving area 11c3) of the third power generating device 11c in a stacked manner in the normal direction to the top surface of the third base portion 12c at the third reference position P3. Specifically, when the third base portion 12c is stored in the second side recess portion 2c, i.e., when the upper surface of the third base portion 12c is perpendicular to the y direction, the third holding device 13c holds the three light receiving areas of the third power generation device 11c stacked in the y direction (fifth closed state). When the top surface of the third base portion 12c is perpendicular to the z direction, the third holding device 13c holds the three light receiving regions of the third power generating device 11c stacked in the z direction (fourth closed state). When in use, the third holding device 13c holds the three light receiving areas of the third power generation device 11c in a positional relationship in which the three light receiving areas are shifted in the x or y direction and do not overlap when viewed from the normal direction of the top surface of the third base portion 12c (third open state). This ensures three times the light receiving area compared to when not in use, making it possible to obtain more power from sunlight.

[0146] (Effect of preventing physical interference between the first power generation device 11a, the second power generation device 11b, and the third power generation device 11c) When in use, the first holding device 13a holds the seven light receiving areas of the first power generating device 11a in the first open state in a positional relationship where they do not overlap with the three light receiving areas of the second power generating device 11b in the second open state, and the three light receiving areas of the third power generating device 11c in the third open state, when viewed from the normal direction of the top surface of the first base portion 12a. Therefore, by efficiently arranging the seven light-receiving areas of the first power generating device 11a, the three light-receiving areas of the second power generating device 11b, and the three light-receiving areas of the third power generating device 11c in the space including the area above the vehicle 1, it becomes possible to obtain a large amount of electricity from sunlight.

[0147] (Effect of storing the second power generating unit 11b and the third power generating unit 11c in the recessed portion on the side of the vehicle 1) When not in use, at least a portion of the second power generating unit 11b is stored in the first side recess 2b on the left side of the luggage compartment of the vehicle body 2 (third closed state). When not in use, at least a portion of the third power generating unit 11c is stored in the second side recess 2c on the right side of the luggage compartment of the vehicle body 2 (fifth closed state). Therefore, it is possible to reduce the dimension (height) of the vehicle 1 in the z direction, compared to a configuration in which the second power generation plant 11b and the third power generation plant 11c are stacked on the first power generation plant 11a. Also, compared to a configuration in which the second power generating unit 11b and the like are disposed on the side surface without providing a recess, it is possible to reduce the dimension (width) of the vehicle 1 in the y direction.

[0148] (Effect of Adjusting the Tilt of the First Base Part 12a, the Second Base Part 12b, and the Third Base Part 12c) By adjusting the inclination of the upper surfaces of the first base portion 12a, the second base portion 12b, and the third base portion 12c, it is possible to adjust the orientation of the light receiving surfaces of the seven light receiving areas of the first power generating device 11a, the three light receiving areas of the second power generating device 11b, and the three light receiving areas of the third power generating device 11c. In particular, the tilt adjustment is performed using a mechanism that moves the upper surfaces of the second base portion 12b and the third base portion 12c from a stored state in the recessed portion to a use state, so that the structure can be simplified compared to a configuration that uses separate mechanisms.

[0149] (Front-back and left-right balance effect) In the first embodiment, in the first power generation device 11a, the light receiving areas (14th light receiving area 11a4, 15th light receiving area 11a5) that protrude forward in the y direction are provided at a higher position than the light receiving areas (16th light receiving area 11a6, 17th light receiving area 11a7) that protrude backward in the y direction. In the second power generating device 11b, the light receiving region (the twenty-second light receiving region 11b2) that protrudes backward in the y direction is provided at a higher position than the light receiving region (the twenty-third light receiving region 11b3) that protrudes forward in the y direction. In the third power generating device 11c, the light receiving region (the 32nd light receiving region 11c2) protruding backward in the y direction is provided at a higher position than the light receiving region (the 33rd light receiving region 11c3) protruding forward in the y direction. Therefore, the light receiving areas at higher positions and the light receiving areas at lower positions are arranged in a well-balanced manner in the front and rear of the y direction, making the device less likely to tip over.

[0150] (Example of front and rear balance adjustment) From the standpoint of balance, the light receiving areas protruding forward in the y direction (14th light receiving area 11a4, 15th light receiving area 11a5) may be located at a lower position than the light receiving areas protruding backward in the y direction (16th light receiving area 11a6, 17th light receiving area 11a7), the light receiving area protruding backward in the y direction (22nd light receiving area 11b2) may be located at a lower position than the light receiving area protruding forward in the y direction (23rd light receiving area 11b3), and the light receiving area protruding backward in the y direction (32nd light receiving area 11c2) may be located at a lower position than the light receiving area protruding forward in the y direction (33rd light receiving area 11c3).

[0151] (Effect of using the electric power obtained by the first power generating unit 11 to drive the motor 50 of the vehicle 1) The first power generating unit 11 (first power generating device 11a, second power generating device 11b, third power generating device 11c) has a larger light receiving area than a solar panel mounted on the roof of a normal vehicle. Therefore, it becomes possible to store in the first power storage device 21, etc., the electric power required for a longer running time than that of the normal vehicle.

[0152] (Application examples of the first power generating unit 11a, the second power generating unit 11b, and the third power generating unit 11c) In the first embodiment, an example has been described in which the first power generating section 11 has three power generating devices (the first power generating device 11a, the second power generating device 11b, and the third power generating device 11c). However, the first power generating section 11 may be in a form having only the first power generating device 11a, in a form having only the first power generating device 11a and the second power generating device 11b, or in a form having only the first power generating device 11a and the third power generating device 11c.

[0153] (Example of application of a method for holding a stationary light receiving area) In the first embodiment, an example has been described in which the twelfth light receiving region 11a2 is fixedly held by the first holding device 13a (the twelfth holding region 13a2). However, the light receiving area that does not move in the x and y directions (corresponding to the "central light receiving area" in the claims) is not limited to being held by the first holding device 13a. For example, the light receiving area that does not move in the x and y directions may be provided at the lowest stage of the first power generating device 11a and fixed to the first base portion 12a, or, if the first base portion 12a is omitted, may be fixed to the upper surface 2a of the luggage compartment of the vehicle body 2.

[0154] (Application example of the light receiving area retention method) In the first embodiment, an example has been described in which the holding region is configured with a slide rail or the like that holds the side surface of the light receiving region. However, the holding area may be configured with a slide rail or the like that holds the lower surface of the light receiving area (second embodiment, see FIGS. 7 to 12).

[0155] In the second embodiment, among the holding areas of the first holding device 13a, the one at the top end in the z direction (the eleventh holding area 13a1) holds the eleventh light receiving area 11a1 in a state where it is fixed at the first reference position P1. Furthermore, of the holding areas of the first holding device 13a, six holding areas (the twelfth holding area 13a2 to the seventeenth holding area 13a7) excluding the eleventh holding area 13a1 hold the undersides of the six light receiving areas (the twelfth light receiving area 11a2 to the seventeenth light receiving area 11a7) of the first power generating device 11a, excluding the eleventh light receiving area 11a1, in a state in which they can move laterally (in the x direction or the y direction).

[0156] Specifically, the twelfth holding region 13a2 includes an expandable member, such as a slide rail, that holds the lower surface of the twelfth light receiving region 11a2 in a state in which it can move leftward in the x direction. The thirteenth holding region 13a3 includes an expandable member, such as a slide rail, that holds the lower surface of the thirteenth light receiving region 11a3 in a state in which it can move rightward in the x direction. The fourteenth holding region 13a4 includes an expandable member, such as a slide rail, that holds the lower surface of the fourteenth light receiving region 11a4 in a state in which it can move forward in the y direction. The fifteenth holding region 13a5 includes an expandable member, such as a slide rail, that holds the lower surface of the fifteenth light receiving region 11a5 in a state in which the fifteenth light receiving region 11a5 can move further forward in the y direction. The sixteenth holding region 13a6 includes an expandable member, such as a slide rail, that holds the lower surface of the sixteenth light receiving region 11a6 in a state in which the sixteenth light receiving region 11a6 is movable backward in the y direction.
