FIG. 18 is a perspective view in which the container device 1 is seen from the left side. In FIG. 18, the side surface panel 19 forming a left side surface is omitted. In FIG. 18, for convenience of the description, hatching is attached to each of the upper surface panel 12, the lower surface panel 14, the front surface panel 16, and the rear surface panel 18. As shown in FIG. 18, the upper surface panel 12, the lower surface panel 14, the front surface panel 16, and the rear surface panel 18 attached in such a way are coupled to one another so as to become a rectangular frame shape, in a view from a left-right direction of the housing 10, the rectangular frame shape surrounding the members contained in the housing 10, such as the container mechanism 30 and the inverter unit 80. Accordingly, each panel reinforces one another, and it is possible to perform an increase in the strength of the container device 1.

In this way, in the container device 1, a frame portion is formed by the four members of the upper surface panel 12, the lower surface panel 14, the front surface panel 16, and the rear surface panel 18. According to this, in the container device 1, the frame portion can be formed more easily than the case where the frame portion is formed by a single member. Accordingly, the container device 1 becomes easy to manufacture.

In addition, since the front surface panel 16 and the rear surface panel 18 are fixed to the upper surface panel 12 and the lower surface panel 14, the handles 28 being provided on the front surface panel 16 and the rear surface panel 18, the strength of the container device 1 is secured in the case where a user transports the container device 1 by the user holding the handles 28. In addition, as stated above, in the container device 1, the upper surface panel 12 and the lower surface panel 14 are coupled by the battery case 32. Accordingly, an improvement of the strength of the housing 10 can be performed.

Note that, the present invention is not limited to the above description, and in the case where assembling the container device 1, the upper surface panel 12 and the lower surface panel 14 may be attached to the container mechanism 30, and thereafter the front surface panel 16 and the rear surface panel 18 may be fixed to the upper surface panel 12 and the lower surface panel 14.

FIG. 19 is a side surface view in which the container device 1 is seen from the right side. In FIG. 19, the side surface panel 19 forming a right side surface is omitted. In FIG. 19, for convenience of the description, hatching is attached to each of the upper surface panel 12, the lower surface panel 14, the front surface panel 16, and the rear surface panel 18. Here, the communication unit 120 will be described in detail. As stated above, the communication unit 120 is attached to the terminal unit 24. The communication unit 120 includes communication hardware compliant with short-range wireless communication standards, such as an antenna 122 or a communication circuit. It is possible for the communication unit 120 to communicate, for example, with a terminal device such as a remote control, a smartphone, or a tablet. Note that, Wi-Fi (Registered Trademark) and Bluetooth (Registered Trademark) are provided, in this example, as short-range wireless communication standards. The communication unit 120 is attached to the side of the terminal unit 24, and the communication unit 120 is provided at a position of the housing 10 not exposed to the outside.

In the present embodiment, the communication unit 120 is attached to the terminal unit 24, by the fastening member 150. This fastening member 150 is attached so that a screw head included in the fastening member 150 faces the side surface panel 19 forming a right side surface of the housing 10. Moreover, the communication unit 120 and the fastening member 150 are each disposed at a position exposed to the outside, in the case where the side surface panel 19 is removed.

The communication unit 120 disposed in such a way has a front that is covered by the front surface panel 16, which is a resin material. In the communication unit 120 disposed in such a way, an antenna 122 is disposed on a front surface side and an upper portion side of the container device 1.

In the case where a user uses the container device 1 via the terminal device, it is assumed that the user interface unit 22 and the terminal unit 24 are operated together. In the present embodiment, the communication unit 120 and the antenna 122 are each disposed at a position in the vicinity of the front surface panel 16, and in addition, members are not disposed on a front surface side of the antenna 122, so that the members become a shield. According to this, in the container device 1, an operation using the terminal device can be easily performed. In addition, in the container device 1, communication with the terminal device being hindered is suppressed.

A communication unit terminal 120a is provided in the communication unit 120, the communication unit terminal 120a being capable of connecting a terminal of predetermined wiring or the like. The communication unit terminal 120a is a female-shaped terminal provided so as to be opened toward the rear of the housing 10, along a front-rear direction of the housing 10. Note that, the present invention is not limited to this, and the communication unit terminal 120a may be a male-shaped terminal provided so as to protrude toward the rear of the housing 10, along a front-rear direction of the housing 10.

An activation battery 98 is provided, on one of the side walls 48 disposed along a left-right direction of the housing 10, on the battery case 32. The activation battery 98 is an electrical storage device for supplying electrical power to a processor or various types of electrical components for performing control of the container device 1. When an operator for activating the container device 1 is operated, this activation battery 98 supplies electrical power to the processor, and the container device 1 is driven by having this processor start control of the container device 1. The activation battery 98 supplies electrical power with a voltage lower than a voltage of the battery 100.

The activation battery 98 is attached to the battery case 32 via a fixing bracket 96. The fixing bracket 96 is fixed to each of the side walls 48 of the battery case 32, by having the fixing bracket 96 fastened together to the metal fitting holding portion 49, by the fastening member 150 for fixing the mounting metal fitting 60 to the metal fitting holding portion 49. The activation battery 98 is fixed to the fixing bracket 96 by the fastening member 150 such as a screw member. A bracket buffering material 96a is provided, at a predetermined portion of a surface opposite the battery case 32, on the activation battery 98. The bracket buffering material 96a is formed by a material that includes flexibility such as a rubber material or a sponge material. The fixing bracket 96 comes into contact with the battery case 32 via this bracket buffering material 96a. Accordingly, in the case where transporting the container device 1, or in the case where performing insertion or removal of the battery 100 with respect to the container device 1, the activation battery 98 being vibrated is suppressed, by the bracket buffering material 96a, even in the case where the housing 10 vibrates. In the container device 1, the activation battery 98 is disposed between one of the side walls 48 and one of the side surface panels 19, and in the case where the side surface panel 19 is removed, the activation battery 98 is disposed at a position exposed to the outside.

An activation battery terminal 98a is provided on the activation battery 98, the activation battery terminal 98a being capable of connecting a terminal of a predetermined wiring or the like. The activation battery terminal 98a is a female-shaped terminal provided so as to be opened toward the downside of the housing 10, along an up-down direction of the housing 10. Note that, the present invention is not limited to this, and the activation battery terminal 98a may be a male-shaped terminal provided so as to protrude toward the downside of the housing 10, along an up-down direction of the housing 10.

A connection cable 145 is connected to both the communication unit terminal 120a and the activation battery terminal 98a. The connection cable 145 extends toward the rear of the housing 10, along the lower surface panel 14 of the housing 10, and another end of the connection cable 145 is connected to the inverter unit 80.

As stated above, the communication unit 120 and the activation battery 98 are each disposed at a position exposed to the outside, in the case where the side surface panel 19 is removed. A screw head included in the fastening member 150 is attached so as to face the side surface panel 19 forming a right side surface of the housing 10, the fastening member 150 for fixing each of the communication unit 120 and the activation battery 98. Similarly, the communication unit terminal 120a and the activation battery terminal 98a are each disposed at a position exposed to the outside, in the case where the side surface panel 19 is removed. Accordingly, in the container device 1, by having a user remove one of the side surface panels 19, it is possible for the user to easily perform an operation related to inspection or replacement of the communication unit 120, or it is possible for the user to easily perform an operation related to maintenance such as a wiring connection process of the connection cable 145 or the like. The communication unit 120 corresponds to an “accessory component”, and the activation battery 98 corresponds to an “accessory component, electrical accessory unit”.

(1.2. Operation)

An operation of the container device 1 configured such as above will be described. In the case where the battery 100 is contained in the container device 1, a user opens the cover body 20, and the user rotates the holding handle 62, so that the lock plate 63 is positioned at a predetermined position on a rear side with respect to the insertion/removal slot 31. According to this, each of the lock mechanisms 76 rotates along a left-right direction of the housing 10, and each of the lock mechanisms 76 moves to the outside of the insertion/removal slot 31 in a planar view.

Next, the user holds the battery handle 102, and the user performs insertion into the upper surface opening 13, the frame body opening 51, and the insertion/removal slot 31 from the other end surface 103 side, along the virtual line V. At this time, the user inserts the battery 100 in a posture in which the curved surface 109 is opposite a rear side of the housing 10. As shown in FIG. 10 and FIG. 11, in the case where the battery 100 is attached/detached to/from the container mechanism 30, the attachment/detachment direction becomes a direction along the virtual line V extending along a longitudinal direction of the battery 100, through the center of the battery 100 in a planar view, the attachment/detachment direction being a direction of movement. In other words, the attachment/detachment direction is a direction along a longitudinal direction of the battery 100, and the attachment/detachment direction is a direction along a longitudinal direction of the battery case 32.

As stated above, only the side of the frame body opening 51 positioned on a rear side of the housing 10 is formed so as to be bent in an arc shape. Accordingly, only in the case where the user inserts the battery 100, in a posture in which the curved surface 109 is opposite a rear side of the housing 10, it is possible for the battery 100 to be inserted into the frame body opening 51. In contrast to this, in the case where the user inserts the battery 100 in a different posture to the above-stated posture, the battery 100 cannot pass through the frame body opening 51.

According to this, in the container device 1, the battery terminal 108 and the case side connection terminal 54 being unable to be connected is suppressed, namely, the battery 100 being contained in a posture in which the battery 100 is unable to be electrically connected to the container device 1 is suppressed. Accordingly, in the container device 1, a connection defect of the container device 1 and the battery 100 occurring can be suppressed.

As stated above, each of the buffering materials 42 protrudes from each of the back portion 40 and the side walls 48, on the inside of the battery case 32. Accordingly, when the battery 100 is inserted into the battery case 32 until the end surface 103 come into contact with the back portion 40, each of the buffering materials 42 makes contact with the end surface 103 and each of the battery side surfaces 107. Each of the buffering materials 42 is elastically deformed by the weight of the battery 100. According to this, the battery 100 is stored in the battery case 32. In this way, in the container device 1, by having the buffering material 42 provided, it is possible to suppress the end surface 103 from strongly making contact with the back portion 40, and it is possible to suppress wear of the battery 100 and battery case 32, at the time of insertion of the battery 100.

The battery 100 stored in the battery case 32 has only the end surface 101 positioned more upward than the insertion/removal slot 31. In other words, the battery 100 stored in the battery case 32 has the end surface 101 and the battery handle 102 exposed from the battery case 32.

When the battery 100 is stored in the battery case 32, the user rotates the holding handle 62, until the lock plate 63 is positioned at a predetermined position above the insertion/removal slot 31, such as shown in FIG. 13. In accordance with this rotation of the holding handle 62, each of the lock mechanisms 76 rotates along a left-right direction of the housing 10, each of the lock mechanisms 76 moves to the inside of the insertion/removal slot 31 in a planar view, and each of the pressing portions 77 comes into contact with the end surface 101 of the battery 100. In addition, by rotation of the holding handle 62, the case side connection terminal 54 moves to the inside of the battery case 32, through the terminal hole 41, and the case side connection terminal 54 is connected to the battery terminal 108. According to this, the container device 1 and the battery 100 are electrically connected.

Afterwards, the user rotates the cover body 20 to block the upper surface opening 13. At this time, as shown in FIG. 11, the expanded portion 21 comes into contact with the holding handle 62 from a rear side of the housing 10, and the expanded portion 21 restricts rotation of the holding handle 62. According to this, in the container device 1, the container device 1 and the battery 100 are electrically connected, and thereafter the holding handle 62 being rotated is restricted, even in the case where the container device 1 is disposed in any posture.

On the other hand, in the case where the lock plate 63 is not positioned at a predetermined position above the insertion/removal slot 31, namely, in the case where containment of the battery 100 is not completed by the container mechanism 30, when the cover body 20 is rotated so as to block the upper surface opening 13, a lower surface of the expanded portion 21 comes into contact with the lock plate 63. According to this, the upper surface opening 13 being blocked by the cover body 20 is inhibited. Accordingly, in the container device 1, in the case where containment of the battery 100 is not completed, use starting is suppressed.

As stated above, the holding handle 62 is provided so as to rotate along a front-rear direction of the housing 10, the holding handle 62 extending along a left-right direction of the housing 10.

When the holding handle 62 is rotated until the lock plate 63 moves to an upper side with respect to the insertion/removal slot 31, each of the lock mechanisms 76 has rotation that is restricted by the holding handle 62, and each of the lock mechanisms 76 presses the end surface 101 of the battery 100. According to this, each of the pressing portions 77 elastically deforms to be in close contact with the end surface 101. In contrast to this, the end surface 103 of the battery 100 is held by each of the buffering materials 42, while the end surface 103 is pressed by a repellant force of each of the buffering materials 42. In this way, the battery 100 is contained so as to be sandwiched by each of the lock mechanisms 76 and each of the buffering materials 42, along a longitudinal direction of the battery 100. Accordingly, it is possible for the battery case 32 to more firmly contain the battery 100.

In addition, when the battery 100 is contained in the container mechanism 30, each of the battery side surfaces 107 positioned in a left-right direction of the housing 10, on an upper end side of the battery 100, are disposed at a position in the vicinity of the protruding portion 52 provided on the case frame body 50. According to this, the battery 100 has movement that is restricted along a left-right direction of the housing 10 on the upper end side. Accordingly, in the container device 1, vibrations and positional displacement of the battery 100 can be suppressed, on the end surface 101 side of the battery 100.

As stated above, each of the case frame body 50 and the buffering material 42 is a member with a highest frequency of coming into contact with the battery 100. Since each of the case frame body 50 and the buffering material 42 is formed separate from the battery case 32, in the container device 1, only the case frame body 50 or the buffering material 42 can be easily exchanged, even in the case where deformation or damage occurs in each of the case frame body 50 and the buffering material 42. In addition, in the container device 1, it is possible to manufacture the shape of the case frame body 50 and the shape of buffering material 42 by more finely adjusting these shapes. In addition, since the case frame body 50 is formed by a material including a higher strength or rigidity than a material of the battery case 32, deformation of the case frame body 50 can be suppressed.

The above-stated embodiment exemplifies one aspect of the present invention, and the above-stated embodiment can be arbitrarily modified and applied in a range that does not deviate from the content of the present invention.

For example, while the container device 1 of the present embodiment is an electrical power supply device for supplying electrical power to outside of the device, by making the battery 100 stored inside of the housing 10 a power source, the present invention is not limited to this, and the container device 1 may be an electrical power consuming device including an electrical power consuming portion integrally formed with this device, such as a light source or voice output device.

Moreover, for example, in the above-stated embodiment, while the case frame body 50 is formed separate from the battery case 32, the present invention is not limited to this, and the case frame body 50 may be integrally formed with the battery case 32.

In addition, the battery terminal 108 may be formed so as to have a position and shape in which the battery 100 becomes a rotationally symmetrical shape.

In the above-stated embodiment, while the buffering material 42 is provided, the buffering material 42 may be omitted, and a thickness dimension of the pressing portion 77 may be increased. Moreover, for example, the pressing portion 77 and the buffering material 42 may be formed by the same material.

While the protruding portion 52 is provided on the case frame body 50, the present invention is not limited to this, and the protruding portion 52 may be provided on the battery case 32. The protruding portion 52 may be provided at any position in a longitudinal direction of the battery case 32. Moreover, in this case, the container device 1 may have the case frame body 50 omitted.

In the above-stated embodiment, while the container device 1 and the container mechanism 30 contain the battery 100 including a battery cell inside as an electrical storage device, the present invention is not limited to this, and the container device 1 and the container mechanism 30 may contain another electrical storage device such as a capacitor.

Moreover, for example, the container device 1 may include a storage unit of fuel used for power generation, such as a hydrogen container for storing hydrogen used in a fuel cell, or a so-called portable hydrogen tank.

Moreover, for example, the container device 1 may include a combustion engine such as an engine, and the container device 1 may attachably/detachably contain a container for storing liquid fuel such as gasoline combusted in the combustion engine, or the container device 1 may attachably/detachably contain a container for storing gaseous fuel such as hydrogen. In this way, the container device 1 is not limited to a portable energy storage device, and the container device 1 may attachably/detachably contain a container for storing an energy source such as fuel. In this case, the container device 1 includes a mechanism for storing electrical power from an energy source such as hydrogen.

In the above-stated embodiment, while the container device 1 includes a power supply function and a power charging function, the present invention is not limited to this, and the container device 1 may include only a power supply function, or the container device 1 may include only a power charging function.

The directions such as a horizontal direction and a vertical direction, and the various types of shapes, in the above-stated embodiment, include a so-called equivalent range, which accomplishes the same working effect as these directions and shapes, unless otherwise noted.
