The boundary line 40a passes through the center of each of the spherical parts 38a from each of a pair of corners located on one diagonal line in the plane of the inner part 40 in plan view. That is, the boundary line 40a extends along the diameter of each of the spherical portions 38a in plan view.
Thereby, the boundary line 40a passes through a position spaced apart from the terminal hole 41 by a predetermined distance. Therefore, in the battery case 32, it is possible to improve the strength of the second member 32b in which the terminal hole 41 is provided.

The boundary line 40a passes between each of the inner bosses 45 at the center of the inner part 40 after passing through the center of each of the spherical parts 38a. Therefore, the boundary line 40a becomes a dividing line that draws an S-shape when the inner part 40 is viewed from above.

As a result, the contact point between the edge portion 48a and the edge portion 47a and the contact point between the edge portion 48b and the edge portion 48d become a boundary line in the cylindrical portion of the battery case 32.

The first member 32a and the second member 32b are each connected by a so-called snap fit.

As shown in FIG. 3, both ends of the terminal holding plate 72 in the longitudinal direction are rotatably connected to the other end of each of the link plates 70 via a plate shaft 74.
The terminal holding plate 72 is a plate-like member having a predetermined length. One end of the terminal holding plate 72 in the longitudinal direction is arranged along the lower side of one side wall 48 located in the left-right direction. The terminal holding plate 72 passes from the lower side of the one side wall 48 to the inner part 40 and the lower side of the terminal hole 41, and is disposed along the lower side of the one side wall 48 with the other end located in the left-right direction. Therefore, the terminal holding plate 72 is bent into a substantially U-shape when viewed from the front of the housing 10 .

As shown in FIG. 5, a case-side connection terminal 54 is provided in the terminal holding plate 72 at a position facing the terminal hole 41.

When the lock plate 63 of the holding handle 62 is moved above the loading/unloading port 31, the rotation of each of the locking mechanisms 76 is restricted by each of both ends of the holding handle 62 so that it is located inside the loading/unloading port 31. be done.

As shown in FIG. 9, a lower frame 110 is provided below the inner part 40 in the vertical direction of the battery case 32.
The lower frame 110 is a plate-like member having a predetermined length. The lower frame 110 has one end in the longitudinal direction arranged along the lower part of one side wall 48 located in the left-right direction. The lower frame 110 passes from the lower part of the one side wall 48 to the deep part 40 and below the terminal hole 41, and is disposed along the lower part of the one side wall 48 with the other end located in the left-right direction. Therefore, the lower frame 110 is bent into a substantially U-shape when viewed from the front of the housing 10 . Below the inner part 40 , the lower frame 110 passes closer to the front side of the housing 10 than the terminal holding plate 72 .

A plurality of screw holes 111 that open toward the inner part 40 are provided at straight portions of the lower frame 110. Each of the screw holes 111 is jointly fastened to the inner boss 45 by a fastening member 150. Thereby, lower frame 110 is fixed to battery case 32.

The holding handle 62, each of the mounting fittings 60, each of the fitting holders 49, and the lower frame 110 are connected to each other and fixed to the battery case 32.

As a result, the battery case 32 is reinforced by the holding handle 62, each of the mounting fittings 60, each of the fitting holders 49, and the lower frame 110. In addition, the housing mechanism 30 can more reliably hold the battery 100 housed in the battery case 32.

Furthermore, the holding handle 62 and the lower frame 110 are arranged astride the first member 32a and the second member 32b, and are connected to each other via each of the mounting fittings 60 and each of the fitting holders 49. Ru. As a result, the battery case 32 is constructed by the holding handle 62, the lower frame 110, each of the mounting brackets 60, and each of the bracket holders 49, which are connected in a frame shape when viewed from the front side of the housing 10. , the entire circumference is surrounded.

Thereby, the first member 32a and the second member 32b are more firmly connected, and the rigidity and strength of the battery case 32 can be improved.
In this embodiment, the holding handle 62 and the lower frame 110 are formed of a metal material having higher strength than the battery case 32.
The holding handle 62 and the lower frame 110 each correspond to a "connecting member" in the present disclosure, the holding handle 62 corresponds to a "first connecting member" in the present disclosure, and the lower frame 110 corresponds to a "first coupling member" in the present disclosure. This corresponds to a "second connecting member."

As shown in FIG. 3, in the battery case 32, a starting battery 94 is provided on the side wall 48 disposed on the front side of the housing 10 in the front-rear direction. The starting battery 94 is a power storage device that supplies power to the processor 130 that controls the battery 100, the control device that controls the housing device 1, various electrical components, and the like. When the operator for starting the accommodation device 1 is operated, the activation battery 94 supplies power to the processor 130, and the processor 130 starts controlling the accommodation device 1, thereby driving the accommodation device 1. Startup battery 94 provides power at a lower voltage than battery 100.
The starting battery 94 is attached to the battery case 32 by being fastened together with the battery boss 42 by a fastening member 150.

In the battery case 32, a blower 140 is provided on the side wall 48 disposed on the front side of the housing 10 in the front-rear direction. The blower 140 is a device that sends air into or from the inside of the battery case 32 by rotating an impeller housed in the housing 142. The blower 140 includes two blower openings 141 and 143 through which air sent by the impeller can enter and exit. In this embodiment, the blower 140 includes a sirocco fan, but is not limited to this, and may be other impellers such as an axial fan.

The blower 140 is attached to the battery case 32 by being fastened together with the blower boss 44 by a fastening member 150. In this case, the blower 140 is attached so that the blowing opening 141 overlaps the communication hole 43.
As described above, the blower 140 is arranged on the lower side of the battery case 32 in the vertical direction. Thereby, in the housing device 1, even when the user attaches and detaches the battery 100, the blower 140 becomes difficult to be visually recognized by the user. In addition, the ventilation opening 141 is covered by the mesh shape of the communication hole 43 when viewed from inside the battery case 32 . Therefore, the user is prevented from coming into contact with the blower 140.

In the housing device 1, the starting battery 94 and the blower 140 are arranged between the battery case 32, the display unit 22, and the terminal unit 24.

Here, the fixing structure between the housing 10 and the battery case 32 will be explained.
The top panel 12 and the battery case 32 are arranged so that each of the screw holes 15 and each of the screw holes 33 overlap when the housing 10 is viewed from above. In this state, the fastening members 150 are screwed into each of the screw holes 15 and 33, thereby fixing the top panel 12 and the battery case 32.

The upper edge support member 87 is attached to the battery case 32 by fastening both ends of the upper edge support member 87 into each of the screw holes 33 located on the rear side of the housing 10 using a fastening member 150. Thereby, in the storage device 1, the top panel 12, the battery case 32, and the upper edge support member 87 are connected while suppressing an increase in the number of parts.

[1.2. motion]
The operation of the accommodation device 1 configured as described above will be explained.
When the user stores the battery 100 in the storage device 1, the user opens the lid 20 and positions the lock plate 63 at a predetermined position on the rear side of the housing 10 with respect to the loading/unloading port 31. Rotate the holding handle 62. As a result, each of the locking mechanisms 76 is rotated along the left-right direction of the housing 10 and moved outward from the access port 31 in a plan view.

Next, the user grasps the battery handle 102 and inserts it into the upper surface opening 13 and the loading/unloading port 31 from the other end surface 103 side along the imaginary line I. At this time, the user inserts the battery 100 with the curved surface 109 facing the rear side of the housing 10.
As shown in FIGS. 10 and 11, when the battery 100 is attached to and removed from the accommodation mechanism 30, the attachment and detachment direction, which is the direction in which it moves, passes through the center of the battery 100 in a plan view and runs along the longitudinal direction of the battery 100. The direction is along the extending virtual line I. In other words, the attachment/detachment direction is a direction along the longitudinal direction of the battery 100 and the longitudinal direction of the battery case 32.

As described above, only the side wall 47 is formed to curve in an arc shape. Therefore, the battery 100 can be inserted into the battery case 32 only when the user inserts the battery 100 with the curved surface 109 facing the rear side of the housing 10 .
On the other hand, if the user inserts the battery 100 in a posture different from the above-described posture, the battery 100 cannot be accommodated in the battery case 32.

This prevents the battery 100 from being housed in the housing device 1 in a position where the battery terminal 108 and the case-side connection terminal 54 cannot be connected, that is, the battery 100 cannot be electrically connected to the housing device 1. be done. Therefore, in the accommodation device 1, occurrence of a connection failure between the accommodation device 1 and the battery 100 is suppressed.

The end face 101 of the battery 100 housed in the battery case 32 is located above the loading/unloading port 31. In other words, the end face 101 and the battery handle 102 of the battery 100 housed in the battery case 32 are exposed from the battery case 32 .

When the battery 100 is housed in the battery case 32, the user rotates the holding handle 62 until the lock plate 63 is located at a predetermined position above the loading/unloading port 31, as shown in FIG. As the holding handle 62 rotates, each of the locking mechanisms 76 rotates along the left-right direction of the casing 10, moves inside the loading/unloading port 31 in plan view, and comes into contact with the end surface 101 of the battery 100. come into contact with
Further, by rotating the holding handle 62, the case side connection terminal 54 moves into the interior of the battery case 32 through the terminal hole 41 and is connected to the battery terminal 108. Thereby, the housing device 1 and the battery 100 are electrically connected.

Thereafter, the user rotates the lid 20 to close the top opening 13. At this time, as shown in FIG. 9, the bulging portion 21 comes into contact with the holding handle 62 from the rear side of the housing 10, and restricts rotation of the holding handle 62.
As a result, in the accommodation device 1, the holding handle 62 can be rotated regardless of the orientation in which the accommodation device 1 is installed after the accommodation device 1 and the battery 100 are electrically connected. is regulated.

On the other hand, if the lock plate 63 is not located at the predetermined position above the loading/unloading port 31, that is, if the housing mechanism 30 has not completed housing the battery 100, the lid body 20 is rotated to close the top opening 13. When moved, the lower surface of the bulge 21 comes into contact with the lock plate 63. This prevents the top opening 13 from being closed by the lid 20. For this reason, in the housing device 1, when housing of the battery 100 is not completed, it is suppressed from starting to use the battery 100.

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

When the holding handle 62 is rotated until the lock plate 63 moves above the loading/unloading port 31, the rotation of each of the locking mechanisms 76 is restricted by the holding handle 62, and the end face 101 of the battery 100 is Press.

As a result, movement of the battery 100 along the vertical and horizontal directions of the housing 10 on the upper end side is restricted. Therefore, in the housing device 1, vibration and displacement of the battery 100 are suppressed on the end surface 101 side of the battery 100.

When the battery 100 is housed in the battery case 32, the contact portions 106 fit into each of the first receiving portions 36 and the second receiving portions 38 and are held. As a result, movement of the battery 100 along the front-rear direction and the left-right direction of the housing 10 at the lower end side is restricted.

As described above, the inner part 40 is formed so that its entire circumferential length is substantially the same as the entire circumferential length of the access port 31 . Therefore, in each of the side walls 48, the plane located inside the battery case 32 stands up substantially perpendicularly from the inner part 40.
As a result, in the battery case 32, the clearance between the inner peripheral surface of the battery case 32 and the battery 100 is formed smaller over the entire vertical direction of the battery case 32. Therefore, in the battery case 32, the battery 100 housed in the battery case 32 is suppressed from vibrating in a direction intersecting the vertical direction of the battery case 32.

FIG. 12 is a perspective view of the first member 32a showing the direction in which the mold is extracted. FIG. 13 is a perspective view of the second member 32b showing the direction in which the mold is extracted. In FIGS. 12 and 13, arrows indicate the direction in which the mold is extracted.
Here, manufacturing of the first member 32a and the second member 32b will be explained. As described above, the first member 32a and the second member 32b are formed by injection molding or plastic working, and in this embodiment, both are formed from a resin material.
As shown in FIGS. 12 and 13, when the first member 32a and the second member 32b are formed, the mold is extracted in the direction shown by the arrow. Specifically, in the first member 32a, along the slope of the upper surface of the wedge-shaped part 38b, from each corner of the deep part 40 adjacent to the wedge-shaped part 38b toward the edge 48b and the loading/unloading opening 31, The mold is extracted. In the second member 32b, the mold is pulled out from each corner of the inner part 40 adjacent to the wedge-shaped part 38b toward the edge 48d and the loading/unloading opening 31.

Thereby, in the battery case 32, each of the side walls 47, 48 and the inner part 40 can be formed into a more complicated shape. Furthermore, since the mold is extracted so as to pass through the dividing point between the first member 32a and the second member 32b, in other words, on the boundary line, the battery case 32 provides a clearance sufficient to allow the mold to be extracted. The inlet/outlet opening 31 can be formed without any problems. Therefore, in the battery case 32, the clearance between the inner peripheral surface of the battery case 32 and the battery 100 can be formed smaller.

Moreover, since the boundary line 40a is located so as to pass through the diameter of each of the spherical parts 38a in plan view, when the mold is extracted from each of the first member 32a and the second member 32b, the spherical parts 38a The parts of the mold that form each of the parts can be easily extracted.

The embodiment described above is an example of one aspect of the present invention, and can be arbitrarily modified and applied without departing from the spirit of the present invention.

In the embodiment described above, the battery case 32 has a rectangular cylindrical shape, but is not limited to this, and may have a cylindrical shape, for example, like the battery case 132 shown in FIG. 14. This battery case 132 includes a boundary line 40a passing through the center of the inner part 40.

In the embodiment described above, the case-side connection terminal 54 is moved up and down by the link mechanism operated by the holding handle 62, but the present invention is not limited to this, and the case-side connection terminal 54 may be moved up and down by an actuator such as a motor. Further, the case-side connection terminal 54 may be provided in a state where it is not driven and always protrudes from the inner part 40.

In the embodiment described above, the battery terminal 108 is a female terminal, but is not limited thereto, and may be a male terminal. In this case, the battery terminal 108 passes through the terminal hole 41.

In the embodiment described above, the blower 140 blows air from the inside of the battery case 32 to the outside, but the blower 140 is not limited to this, and may blow air from the outside of the battery case 32 to the inside. good.

In the above-described embodiment, the power device is the battery 100 that stores electric power, but is not limited to this. For example, the fuel used for power generation, such as a hydrogen container that stores hydrogen used in a fuel cell, a so-called portable hydrogen tank, etc. It may be. That is, the housing device 1 is not limited to power equipment, and may be one that removably houses an energy source accumulator. In this case, the accommodation device 1 is equipped with a mechanism for generating electricity from hydrogen.

In the embodiment described above, the accommodation device 1 may include a sealing structure that seals the gap between the accommodation mechanism 30 and the battery 100 accommodated in the accommodation mechanism 30 to make it liquid-tight. In this case, the lid 20 may be omitted from the storage device 1.

Although the above-described contact portion 106 protrudes from the end surface 103, the present invention is not limited thereto, and the contact portion 106 may be formed by recessing the end surface 103 in a hemispherical or spherical shape. In this case, each of the receiving parts 35 may have a shape that projects toward the inside of the battery case 32 on a plane located inside the battery case 32 in the inner part 40 . In this case, the contact portion 106 is held by each receiving portion 35 fitting into the contact portion 106.
