Summary of the Invention

Problems to be Solved by the Invention

[0004] In view of such a conventional situation, an object of the present invention is to provide a mobile power vehicle having a simple structure, high versatility, and not interfering with running, and a frame used therefor.

Means for Solving the Problems

[0005] To achieve the above objective, the mobile power supply vehicle according to the present invention is characterized in that a power generation system comprising at least a generator and a power supply unit for supplying power to the outside is mounted on the cargo bed of a vehicle, wherein a frame made of a plurality of support columns arranged at appropriate intervals and horizontal members connecting the plurality of support columns is erected around the power generation system on the cargo bed, and at least three surfaces of the circumferential surface of the frame, the surface parallel to the direction of travel of the vehicle and the rear side in the direction of travel, are provided between adjacent support columns, and the cover members are closed when the vehicle is stopped and the power generation system is in operation, and are opened when the vehicle is in motion.

[0006] According to the above configuration, a frame consisting of multiple support columns arranged at appropriate intervals and horizontal members connecting the multiple support columns is erected around the power generation equipment on the cargo bed. This results in a simple structure that can be easily installed according to the size of the power generation equipment (various necessary devices) to be loaded, and offers high versatility. Furthermore, at least three surfaces of the frame's circumferential surface—the surface parallel to the vehicle's direction of travel and the surface on the rear side in the direction of travel—are provided with openable and closable covering members between adjacent support columns. These are closed when the vehicle is stopped and the power generation equipment is in operation, and opened when the vehicle is in motion. This conceals the power generation equipment when it is in operation, visually reducing its presence. For example, at events, this can alleviate a sense of psychological pressure and allow the equipment to blend in with the surrounding scenery and the atmosphere of the venue. Moreover, since it is open when the vehicle is in motion, it can travel smoothly without being affected by the wind and does not obstruct the driver's rearward visibility, thus not hindering driving.

[0007] In the above-described configuration, the multiple support columns and the horizontal members are preferably truss members. This allows for weight reduction of the frame itself while also ensuring sufficient strength (rigidity) to support the covering members. Moreover, because truss members have a hollow structure, air resistance during travel can be reduced.

[0008] In the above-described configuration, the covering member preferably includes a curtain member that can move up and down, and the surface of the curtain member is configured as an information display area. Because it includes a curtain member that can move up and down, opening and closing can be done with little force, resulting in good workability. Also, because it is lightweight, it does not affect the vehicle's movement. Furthermore, because the surface of the curtain member is configured as an information display area, it is possible to provide, for example, advertising information or enhance decorative visual effects when the vehicle is stopped and the power generation equipment is in operation.

[0009] In the above-described configuration, it is preferable that the support column on the rear side of the frame in the direction of travel is provided with a projection that protrudes from the lower part of the support column and whose end is close to the rear surface of the cargo bed. This allows space to be formed at the rear of the cargo bed and outside the frame. In this case, it is preferable that the supply unit be provided outside the frame and on the rear side of the cargo bed. This allows the space formed at the rear of the cargo bed and outside the frame to be used as a workspace, and there is no need to open and close the cover member during work, resulting in improved work efficiency.

[0010] Furthermore, in any of the above characteristic configurations, the power generation equipment further comprises a storage battery equipped with at least an operating unit, wherein the storage battery is positioned behind the loading platform than the generator and the side on which the operating unit is located faces the rear of the loading platform. This allows the side with the operating unit to be located near the supply unit, further improving work efficiency.

[0011] In any of the above configurations, a solar cell panel may be installed on the upper surface of the frame. Alternatively, a peropskite solar cell may be provided on the covering member. This increases the amount of stored energy (power generated) and improves convenience.

[0012] Furthermore, in order to achieve the above objective, the frame used in the mobile power supply vehicle according to the present invention is configured in a mobile power supply vehicle in which a power generation facility comprising at least a generator and a supply unit for supplying power to the outside is mounted on the cargo bed of a vehicle, and consists of a plurality of support columns arranged at appropriate intervals on the cargo bed and horizontal members connecting the plurality of support columns, the plurality of support columns and the horizontal members assembled around the power generation facility, and at least three of the surfaces formed by the plurality of support columns and the horizontal members, the surface parallel to the direction of travel of the vehicle and the surface on the rear side in the direction of travel, have openable and closable covering members provided between adjacent support columns, the covering members being closed when the vehicle is stopped and the power generation facility is in operation, and being opened when the vehicle is in motion. [Effects of the Invention]

[0013] According to the features of the mobile power supply vehicle and the frame used therein according to the present invention, it is possible to have a simple structure that is highly versatile and does not hinder movement.

Embodiment for Carrying out the Invention

[0016] Next, the first embodiment of the present invention will be described in more detail with appropriate reference to FIGS. 1 to 6. The mobile power supply vehicle 1 according to the present invention generally includes a power generation facility 5 mounted on a loading platform 3 of a vehicle 2, which at least includes a generator 51 and an output panel 52 as a supply unit for supplying power to the outside. In this embodiment, as the vehicle 2, for example, a 4t flat truck (medium flat car) is used. The loading platform 3 includes a rectangular loading platform floor 31, left and right side girders 32, 32 erected at the ends of the loading platform floor 31, and a rear girder 33 at the rear in the traveling direction X of the vehicle 2 (the longitudinal direction of the loading platform 3).

[0017] A frame body 6 is erected around the power generation facility 5 on the loading platform floor 31. This frame body 6 is composed of a plurality of columns 61 arranged at appropriate intervals and a horizontal member 62 connecting the plurality of columns 61, and presents a rectangle conforming to the shape of the loading platform 3. In this embodiment, the horizontal member 62 is composed of an upper horizontal member 63 and a lower horizontal member 64 connecting the upper and lower ends of adjacent columns 61. Further, the columns 61 and the upper and lower horizontal members 63, 64 are all lightweight trusses (truss materials) made of aluminum, lightweight steel, etc., achieving both weight reduction and high strength.

[0018] Among the plurality of support columns 61, on the rear support columns 61c, 61c of the frame body 6 on the rear side in the traveling direction X, there are provided protruding portions 65, 65 that protrude from the lower part and whose ends are close to the rear spoiler 33 which is the rear surface of the loading platform 3. The longitudinal length L1 of the frame body 6 along the traveling direction X is equal to the longitudinal length L2 of the loading platform floor 31. By arranging the frame body 6 on the side of the cabin 4, the protruding portions 65 can form a space SP on the rear side B of the loading platform 3 and outside the frame body 6. Moreover, since this protruding portion 65 is close to the rear spoiler 33, the displacement (movement) of the frame body 6 in the traveling direction X is also suppressed. In addition, the lateral length L3 of the frame body 6 is equal to the lateral length L4 of the loading platform floor 31, and the displacement (movement) of the frame body 6 in the direction Y orthogonal to the traveling direction X is also suppressed.

[0019] Furthermore, on one of the rear support columns 61c, there is provided a second protruding portion 66 that protrudes toward the rear spoiler 33, and the output board 52 is attached thereto. Moreover, the second protruding portion 66 is formed shorter than the protruding portion 65. Thereby, the output board 52 can be positioned in the space SP behind the loading platform 3 formed by the protruding portion 65, so that the operation (work) of the output board 52 becomes easy. Moreover, since the output board 52 is located outside the frame body 6, it is not necessary to open and close the covering member 7 every time an operation (work) is performed, and the workability is also good.

[0020] Here, among the peripheral surfaces of the frame body 6, on three surfaces, namely, the surface (side surface) S1 parallel to the traveling direction X and the surface (rear surface) S2 on the rear side B in the traveling direction X of the frame body 6, there are provided covering members 7 that can be opened and closed between adjacent support columns 61. In this embodiment, the covering member 7 is not provided on the upper and lower surfaces of the frame body 6 and the surface (front surface) S4 facing the cabin 4 of the loading platform 3.

[0021] In this embodiment, a roll screen 70 is used as the openable and closable cover member 7. The roll screen 70 generally consists of a curtain member 71, a winding machine 72 for winding up the curtain member 71, and a string 73 (pull cord) provided at the bottom of the curtain member 71 as an operating part. The winding machine 72 is attached to the rear horizontal upper member 63b of the horizontal upper member 63b, which is located in the direction Y perpendicular to the direction of travel X of the vehicle 2 (the longitudinal direction of the cargo bed 3) and the direction of travel X. The curtain member 71 is moved up and down (opened and closed) by pulling the string 73. Since the three surfaces mentioned above (both sides S1, S1 and the rear surface S2) face the outside, the string 73 is easy to operate and the workability is good.

[0022] Since the curtain member 71 is used outdoors, it is preferably a sheet-like material with excellent durability and weather resistance, and in this embodiment, for example, tarpaulin is used. An information display area C is formed on the surface (the side exposed to the outside) of the tarpaulin 71. For example, advertisements, illustrations, text information, etc., are printed in the information display area C. This allows the curtain member to conceal the power generation equipment 5 at events, for example, while also providing information and adding a decorative visual effect.

[0023] In this embodiment, the power generation equipment 5 generally comprises a generator 51, an output panel 52 as a supply unit, a storage battery 53, and a downtrust 54. As shown in Figure 6, the electricity generated by the generator 51 is stored in the storage battery 53, the stored electricity is voltage-regulated by the downtrust 54, and the power is supplied to the outside via the output panel 52. In this way, since power is supplied from the storage battery 53, if the stored charge is sufficient, power can be supplied without operating the generator 51, thus ensuring quiet operation. In this embodiment, the output panel 52 distributes power to the outside, for example, four single-phase 100V output ports 52a, two single-phase 200V output ports 52b, and one three-phase 200V output port 52c.

[0024] In this embodiment, as shown in Figure 4, the battery 53 includes an operation unit 53a, a breaker unit 53b, and an input / output unit 53c, which are arranged on one side of the battery 53's casing. The battery 53 is positioned behind the cargo bed 3 B, relative to the generator 51, with the side containing the operation unit 53a and other components oriented towards the rear B side. This allows the operation unit 53a and other components of the battery 53 to be positioned near the aforementioned workspace SP, further improving work efficiency.

[0025] In this invention, the power generation equipment 5 is operated while the vehicle 2 is stopped. The frame 6 and cover member 7 are loaded onto the cargo bed 3 in advance and arranged as described above. When the vehicle 2 is in motion, the tarpaulin 72 is raised as shown in Figure 1 to open the sides S1 and rear S2 of the frame 6. As a result, the tarpaulin 72 is not affected by the wind, and the vehicle can travel smoothly and stably without generating noise.

[0026] On the other hand, when the vehicle 2 is stopped at the site and the power generation equipment 5 is activated, the tarpaulin 72 is lowered to close the sides S1 and rear S2 of the frame 6. This conceals the power generation equipment 5 and visually reduces its presence. Furthermore, since the surface of the tarpaulin 72 is configured as an information display area C, it is possible to make the power generation equipment 5 less conspicuous while also improving information provision and visual effects. The openable and closable cover member 7 makes it possible to achieve a high degree of balance between driving safety and efficiency and consideration for the scenery when the vehicle is stopped.

[0027] In this way, by opening the curtain member 71 while the vehicle is in motion, physical obstructions such as wind resistance, flapping, and obstruction of the driver's view can be minimized. On the other hand, by closing the curtain member 71 when the vehicle is stopped, the power generation equipment 5 can be shielded, and the visual impact on the surrounding environment can be mitigated.

[0028] Next, other embodiments of the present invention will be described with reference to Figures 7 to 9. In the following embodiments, the same reference numerals are used for components and other parts as in the above embodiments.

[0029] In the first embodiment described above, the power generation equipment 5 included a generator 51, an output panel 52, a storage battery 53, and a downtrust 54. However, the configuration of the power generation equipment 5 is not limited to this. For example, as shown in Figure 7(a), a storage generator 55 in which the generator 51 and the storage battery 53 are integrated may be included. Also, as shown in Figure 7(b), a storage battery 53' in which the storage battery 53 and the downtrust 54 are integrated may be included. Furthermore, as shown in Figure 7(c), a storage generator 55' in which the generator 51, the storage battery 53, and the downtrust 54 are integrated may be included. On the other hand, the number of various devices such as the generator 51 and the storage battery 52 is not limited to one unit, and as shown in Figure 7(d), multiple units may be included. Note that the above-mentioned devices are merely examples, and the equipment of the power generation equipment 5 is not limited to the above-mentioned devices.

[0030] Furthermore, in the first embodiment described above, a solar cell panel 58 may be laid on the upper surface of the frame 6, as shown in Figure 8(a). Also, as shown in Figure 8(b), a peropskite solar cell 59 can be provided on the covering member 7 (screen member 71). Of course, these can be used in combination to further increase the amount of power generated. Moreover, they may be provided on all of the screen members 71, or they may be provided on only some of the screen members 71 that receive sunlight.

[0031] Finally, we will discuss the possibility of other embodiments of the present invention. In each of the embodiments described above, a 4-ton flatbed truck (medium-sized flatbed truck) was used as an example of vehicle 2. However, vehicle 2 is not limited to this, and may be appropriately selected depending on the type, number, size, etc., of the power generation equipment 5 to be loaded, such as a 2-ton flatbed truck (small flatbed truck), a 10-ton flatbed truck (large flatbed truck), or a light truck.

[0032] In each of the above embodiments, the covering member 7 is composed of a curtain member 71, a winding machine 72, and a cord 73 (pull cord) as an operating part (pull cord type). However, the covering member 7 is not limited to this. Although not shown in the illustration, in addition to the pull cord type described above, for example, a winding machine with a built-in spring member is used to automatically wind up the curtain member by pulling the cord 73 (pull cord) with the spring member (one-touch type), or a chain operating part provided on the side of the winding machine is used to move the curtain member up and down (chain type), and it may also be electrically operated. Furthermore, the method of moving it up and down is not limited to winding, but for example, it may be a method of raising the curtain member while folding it (shade, pleats).

[0033] Furthermore, in each of the above embodiments, the winding machine 72 is attached to each vertical lower horizontal member 63a and horizontal upper horizontal member 63b, and the curtain member 71 is lowered to close the surface between the support columns 61 (closed state). However, it is also possible to attach the winding machine 72 to each vertical lower horizontal member 64a and horizontal lower horizontal member 64b, and raise the curtain member 71 to close the surface between the support columns 61 (closed state).

[0034] Furthermore, in each of the above embodiments, the openable and closable cover member 7 is configured to move vertically using a tarpaulin 71 as a curtain member. However, the direction of movement of the curtain member 71 is not limited to vertical; it may also be in the left-right direction.

[0035] Furthermore, while a curtain member 71 (tarpaulin) was used as the covering member 7 in each of the above embodiments, it is not limited to this. For example, shutters or movable partitions can also be used. However, since it will be used on the loading platform 3 and outdoors, it is desirable that it be durable, waterproof and lightweight, and in this respect, a curtain member 71 such as tarpaulin is superior.

[0036] Furthermore, in each of the above embodiments, the surface of the tarpaulin used as the curtain member 71 was used as the information display area C, and information such as advertisements was printed on the surface of the tarpaulin. However, in addition to printing directly onto the curtain member 71, the printed material may also be detachably attached to the surface of the curtain member 71 as the information display area C.

[0037] In each of the above embodiments, the support columns 61 and horizontal members 62 constituting the frame 6 are made of lightweight trusses, but this is not limited to this. For example, they may be square columns or cylindrical columns, and the material and structure are not particularly limited. However, truss members are superior in that they are lightweight and have high strength. Furthermore, the configuration of the frame 6 is not limited to the above examples, and the number and size of the support columns 61 and horizontal members 62 may be appropriately selected according to the size of the power generation equipment 5 to be installed. [Industrial applicability]
