Description

Technical Field

[0001] The present invention relates to a housing device for holding an electric device.

Background Art

[0002] International Publication No. 2020 / 262630 discloses a holding device for holding an electric device. In this holding device, the opening of the slot (accommodation part) faces vertically upward rather than horizontally. For this reason, in the slot, the upper end of the opening is at a higher position than the upper end of the bottom. That is, the slot has an inclined posture that rises from the bottom toward the opening. International Publication No. 2020 / 262630 exemplifies a power storage device (mobile battery) as an electric device that is detachably accommodated in the slot.

Summary of the Invention

[0003] When the housing device is installed outdoors, the lid member shown in FIGS. 1 and 2 of International Publication No. 2020 / 262630 is provided on the housing device. The lid member closes the opening of the slot. As a result, it is possible to prevent rainwater or the like from entering the slot.

[0004] When the user exchanges the electric device, the lid member can be opened even during rainfall. Even at this time, it is necessary to minimize the possibility of rainwater or the like entering the slot as much as possible.

[0005] An object of the present invention is to solve the above-described problems.

[0006] According to an embodiment of the present invention, there is provided a housing device for housing an electrical device having a first electrical terminal, the housing device including a housing portion for removably housing the electrical device, the housing portion being formed in a bottomed cylindrical shape by an opening, a cylindrical portion in which the opening is formed, and a bottom portion continuous with the cylindrical portion, the housing portion being provided with a second electrical terminal to which the first electrical terminal is detachably connected, or a through hole through which the second electrical terminal passes in a retractable manner is formed in the housing portion, and an extending portion is provided between an outer surface of the electrical device housed in the housing portion and an inner surface of the housing portion and extends in a first direction intersecting the outer surface of the electrical device, the extending portion being disposed at a position where a distance between the extending portion and the opening is smaller than a distance between the second electrical terminal or the through hole and the opening.

[0007] In the present invention, "housing" is not limited to the case where the entire electrical device is housed. For example, a case where a part of the electrical device is housed in the housing portion and a part of the electrical device is exposed from the housing portion is also included in the state of being "housed in the housing portion".

[0008] Rainwater or the like that has entered through the opening of the housing portion flows inside the housing portion along the inner surface of the housing portion. Or, rainwater or the like flows inside the housing portion along the outer surface of the electrical device housed in the housing portion. Here, in the present invention, the extending portion is disposed at a position closer to the opening of the housing portion from the second electrical terminal provided in the housing portion. The extending portion may be disposed at a position closer to the opening of the housing portion from the through hole formed in the housing portion. The extending portion narrows the space between the inner surface of the housing portion where the extending portion is provided and the outer surface of the electrical device. Therefore, rainwater or the like is blocked by the extending portion.

[0009] As a result, it is possible to suppress rainwater or the like from reaching the second electrical terminal. Thereby, the second electrical terminal can be protected from rainwater or the like.

Mode for Carrying Out the Invention

[0011] In the following description, "high position" and "low position" represent the relative up and down when comparing the height positions of two components. Therefore, a component located relatively above may be referred to as a "component at a high position". A component located relatively below may be referred to as a "component at a low position". However, "high position" and "low position" do not necessarily mean that they are arranged vertically one above the other.

[0012] FIG. 1 is a schematic external view of a battery exchanger 10 (accommodating device) according to the first embodiment. Inside the battery exchanger 10, a mobile battery 12 (electrical device) is removably accommodated. The battery exchanger 10 is a device that charges the mobile battery 12 accommodated therein. A user inserts the mobile battery 12 with a low charge rate (SOC: State of Charge) into the battery exchanger 10. The user pulls out another mobile battery 12 that has been charged from the battery exchanger 10.

[0013] The battery exchanger 10 has eight slots 14 (accommodating portions) and one operation panel 16. The mobile battery 12 is accommodated in each of the eight slots 14. When the user accommodates the mobile battery 12 in one slot 14, the battery exchanger 10 starts charging the mobile battery 12 accommodated in that slot 14.

[0014] The slot 14 opens on the front surface 101 of the battery exchanger 10. The front surface 101 of the battery exchanger 10 is inclined with respect to the vertical direction (gravity direction). When the user stands upright facing the front surface 101, the upper part of the front surface 101 is located farther from the user than the lower part of the front surface 101. Thereby, when the user inserts the mobile battery 12 into the slot 14, the user assumes a forward-leaning posture. Therefore, it is easy for the user to insert the mobile battery 12 into the slot 14.

[0015] The operation panel 16 is a device operated by the user. The user operates the operation panel 16 to, for example, pay a fee.

[0016] Figure 2 is a schematic cross-sectional view of the battery exchanger 10. The battery exchanger 10 has a control device 18 above the slot 14. The control device 18 controls the battery exchanger 10. The battery exchanger 10 has a utility space 20 below the slot 14. In the utility space 20, a cooling device or the like is installed as an option. The cooling device cools the inside of the battery exchanger 10.

[0017] Hereinafter, the battery exchanger 10 will be described based on the X-axis, Y-axis, and Z-axis defined as follows. The direction in which the mobile battery 12 is inserted into and removed from the slot 14 is defined as the Z-axis direction. That is, the Z-axis direction corresponds to the insertion / removal direction of the present invention. In the Z-axis direction, the direction from the innermost part of the slot 14 toward the opening is defined as the +Z-axis direction. The +Z-axis direction is the withdrawal direction in which the mobile battery 12 detaches from the slot 14. The -Z-axis direction is the opposite direction of the +Z-axis direction. The -Z-axis direction is the insertion direction of the mobile battery 12 into the slot 14.

[0018] The direction parallel to the width direction of the battery exchanger 10 is defined as the X-axis direction. When the user stands facing the front surface 101 of the battery exchanger 10, the right side in the X-axis direction is defined as the +X-axis direction. The -X-axis direction is the opposite direction of the +X-axis direction and is the left side in the X-axis direction. The direction orthogonal to the Z-axis and the X-axis is defined as the Y-axis direction. In the Y-axis direction, the upper side is defined as the +Y-axis direction. In the Y-axis direction, the lower side is defined as the -Y-axis direction. The Y-axis direction corresponds to the first direction of the present invention. The X-axis direction corresponds to the second direction of the present invention.

[0019] [Configuration of Mobile Battery] In the first embodiment, an aspect of using the mobile battery 12 shown in FIGS. 3 and 4 as an electrical device will be exemplified. The configuration of this mobile battery 12 will be described. FIG. 3 is a perspective view of the mobile battery 12. FIG. 4 is a bottom view of the mobile battery 12.

[0020] As shown in FIGS. 3 and 4, the mobile battery 12 has a bottom case 121, a main case 122, and a top case 123. The bottom case 121 constitutes the bottom surface 12a of the mobile battery 12.

[0021] As shown in FIG. 3, the top case 123 constitutes the upper surface 12b of the mobile battery 12. A handle 24 is provided on the upper surface 12b. The handle 24 has a first grip portion 241 and a second grip portion 242. The user mainly grips the first grip portion 241 to insert and remove the mobile battery 12 with respect to the slot 14.

[0022] The mobile battery 12 has side surfaces 12c, 12d, 12e, and 12f. The bottom surface 12a, the upper surface 12b, the side surfaces 12c, 12d, 12e, and 12f constitute the outer surface of the mobile battery 12.

[0023] One of the outer surfaces, the side surface 12d, is a convex curved surface on the outside. That is, the outer surface of the mobile battery 12 has a convex side surface 12d that protrudes toward the upper inner surface 221 (described later) of the slot sleeve 26. This side surface 12d is the first curved surface portion. Also, the side surfaces 12c, 12e, and 12f are substantially planar. Therefore, the outer shape of the mobile battery 12 is a shape that is rotationally asymmetric with respect to the axis CE shown in FIGS. 3 and 4. The axis CE is a line that passes through the center of the mobile battery 12 and extends along the longitudinal direction of the mobile battery 12. The axis CE coincides with the insertion and extraction direction of the mobile battery 12. The Z-axis direction is the direction in which the mobile battery 12 is inserted into the slot sleeve 26 and the direction in which the mobile battery 12 is pulled out from the slot sleeve 26. In the illustrated example, the entire side surface 12d is curved, but a part of the side surface 12d may be locally curved.

[0024] When the mobile battery 12 is inserted into the slot sleeve 26, the side surface 12d faces vertically upward. Thus, in the first embodiment, the first curved surface portion is provided on the side surface 12d that faces vertically upward within the slot sleeve 26 on the outer surface of the mobile battery 12.

[0025] As shown in FIGS. 3 and 4, a connector 28 (female connector 28) as a first electrical terminal is exposed on the bottom surface 12a. The connector 28 has a female electrical terminal for power transmission and reception and a female communication terminal for communication signal transmission and reception. That is, the connector 28 serves as both an electrical terminal and a communication terminal. The connector 28 is provided in a recess 12g on the bottom surface 12a. That is, the connector 28 is provided at a position slightly closer to the top case 123 from the bottom surface 12a. The connector 28 is closer to the end where the second gripping portion 242 is provided from the center of the bottom surface 12a. The female connector 28 may also be called a receptacle.

[0026] Next, the configuration of the battery exchanger 10 as an accommodating device will be described.

[0027] [Overall Configuration of Slot] As shown in FIGS. 1 and 2, the slot 14 is provided in the battery exchanger 10 in an inclined posture where the opening for inserting and removing the mobile battery 12 is higher than the bottom. The configuration of this slot 14 will be described. FIG. 5 is a perspective view of the slot 14. FIG. 5 shows a state where the mobile battery 12 is not inserted into the slot 14. FIG. 6 is a cross-sectional view of the slot 14. FIG. 6 shows a state where the mobile battery 12 is inserted into the slot 14. The overall configuration of the slot 14 will be described with reference to FIGS. 5 and 6.

[0028] As shown in FIG. 5, the slot 14 has a slot sleeve 26 and a battery lock mechanism 30.

[0029] The slot sleeve 26 holds the mobile battery 12. The slot sleeve 26 has a slot body 29, a slot flange 31, a slot stay 32, and a slot guide 34. The slot body 29 includes a bottom cover 36.

[0030] The slot body 29 is a bottomed cylindrical shape having a bottom portion 29a and a cylindrical portion 29b. The cylindrical portion 29b extends along the Z-axis direction which is the insertion and extraction direction of the mobile battery 12. Therefore, the cylindrical portion 29b surrounds the outer periphery of the mobile battery 12 housed in the slot sleeve 26.

[0031] The cylindrical portion 29b has four side plates, namely a lower side plate 26a, an upper side plate 26b, a left side plate 26c, and a right side plate 26d. Each of the lower side plate 26a, the upper side plate 26b, the left side plate 26c, and the right side plate 26d is, for example, a plate material formed of aluminum. The lower side plate 26a, the upper side plate 26b, the left side plate 26c, and the right side plate 26d are fastened by bolts or the like to form the cylindrical portion 29b of the slot sleeve 26. The cylindrical portion 29b is a hollow body having a substantially quadrangular prism shape. Therefore, when the slot body 29 is viewed from the Z-axis direction, the outer shape of the cylindrical portion 29b is substantially rectangular. The cylindrical portion 29b may be a hollow body having a substantially cylindrical shape. In this case, when the slot body 29 is viewed from the Z-axis direction, the outer shape of the cylindrical portion 29b is substantially circular.

[0032] The cylindrical portion 29b has an inner surface. The inner surface of the cylindrical portion 29b is the four surfaces facing inward of the cylindrical portion 29b on the lower side plate 26a, the upper side plate 26b, the left side plate 26c, and the right side plate 26d. Hereinafter, on the lower side plate 26a, the surface facing inward of the cylindrical portion 29b is denoted as the lower inner surface 220. On the upper side plate 26b, the surface facing inward of the cylindrical portion 29b is denoted as the upper inner surface 221. On the left side plate 26c, the surface facing inward of the cylindrical portion 29b is denoted as the left inner surface 222. On the right side plate 26d, the surface facing inward of the cylindrical portion 29b is denoted as the right inner surface 223.

[0033] The cylindrical portion 29b has an outer surface. The outer surface is the four surfaces facing outward of the cylindrical portion 29b on the lower side plate 26a, the upper side plate 26b, the left side plate 26c, and the right side plate 26d.

[0034] The bottom 29a is connected to the cylindrical portion 29b. The bottom 29a has an inner surface and an outer surface. The inner surface is the surface facing the inside of the slot body 29. The outer surface is the surface facing the outside of the slot body 29. Hereinafter, the inner surface of the bottom 29a is denoted as the bottom inner surface 231. The outer surface of the bottom 29a is denoted as the bottom outer surface 232. The inner surface of the slot sleeve 26 has the lower inner surface 220, the upper inner surface 221, the left inner surface 222, and the right inner surface 223 of the cylindrical portion 29b, and the bottom inner surface 231 of the bottom 29a. The outer surface of the slot sleeve 26 has the outer surface of the cylindrical portion 29b and the bottom outer surface 232 of the bottom 29a.

[0035] The bottom inner surface 231 stops the mobile battery 12 inserted into the slot body 29. That is, the bottom inner surface 231 of the bottom 29a is the insertion end point of the mobile battery 12.

[0036] A through hole 80 penetrating from the bottom inner surface 231 to the bottom outer surface 232 is formed in the bottom 29a. A connector 56 (described later) as a second electrical terminal passes through the through hole 80. When the mobile battery 12 is inserted into the slot body 29, the connector 56 passes through the through hole 80 so as to go from the -Z axis direction to the +Z axis direction. In this case, the connector 56 enters from the outside of the slot body 29 into the inside of the slot body 29. On the contrary, when the mobile battery 12 is pulled out from the slot body 29, the connector 56 passes through the through hole 80 so as to go from the +Z axis direction to the -Z axis direction. In this case, the connector 56 advances from the inside of the slot body 29 to the outside of the slot body 29.

[0037] The separation distance between the through hole 80 and the upper side plate 26b is smaller than the separation distance between the lower side plate 26a and the through hole 80. For this reason, the through hole 80 is closer to the upper side plate 26b than the lower side plate 26a. In other words, the through hole 80 is provided at a position higher than the intermediate position in the vertical direction in the bottom 29a.

[0038] As shown in FIG. 7, five drain holes 69 that communicate the internal space and the external space of the slot body 29 are formed in the lower side plate 26a of the slot body 29. Three drain holes 69 are formed at a position closer to the -Z axis direction than the center of the lower side plate 26a in the Z axis direction. Further, two drain holes 69 are formed at a position closer to the +Z axis direction than the center of the lower side plate 26a in the Z axis direction. As shown in FIG. 2, the -Z axis direction side of the slot 14 is located at a lower position (vertically downward) than the +Z axis direction side of the slot 14. Therefore, most of the liquid that has entered the slot 14 is drained from the three drain holes 69 formed at a position closer to the -Z axis direction than the center of the lower side plate 26a.

[0039] As described above, the slot body 29 is a cylindrical member. As shown in FIG. 6, the slot body 29 has a holding space 281 inside. The holding space 281 is a hole that penetrates the slot body 29 in the Z axis direction. When the mobile battery 12 is held in the slot 14, most of the mobile battery 12 is held in this holding space 281.

[0040] When the slot body 29 is viewed from the Z axis direction, the outer shape of the slot body 29 is substantially rectangular. The slot body 29 has an opening 286 at the end in the +Z axis direction and an opening 287 at the end in the -Z axis direction.

[0041] As shown in FIGS. 5 and 6, a slot flange 31 is attached to the opening 286 in the +Z axis direction of the slot body 29. A slot stay 32 is attached to the slot flange 31 in the +Z axis direction.

[0042] The slot stay 32 has an insertion port 321. The insertion port 321 is a hole that penetrates the slot stay 32 in the Z axis direction. When the slot stay 32 is viewed from the Z axis direction, the insertion port 321 is substantially rectangular. The insertion port 321 is connected to the holding space 281 of the slot body 29.

[0043] As shown in FIGS. 5 and 6, a door 38 is attached to the slot stay 32. As shown in FIG. 6, the door 38 is rotatably provided about a shaft 381. The shaft 381 is attached to the +Y-axis direction side of the slot stay 32. When the mobile battery 12 is not inserted into the slot 14, the door 38 is closed. At this time, the door 38 closes the opening 286 on the +Z-axis direction side of the slot body 29. When the mobile battery 12 is inserted into the slot 14, the mobile battery 12 pushes the door 38 in the -Z-axis direction. As a result, the door 38 rotates and opens about the shaft 381. At this time, the door 38 opens the opening 286 on the +Z-axis direction side of the slot body 29.

[0044] That is, when the mobile battery 12 is not accommodated in the slot sleeve 26, the door 38 closes. Conversely, when the mobile battery 12 is being accommodated in the slot sleeve 26, the door 38 opens inside the slot body 29. In this state, the mobile battery 12 is further inserted into the slot body 29. The door 38 corresponds to the door portion of the present invention.

[0045] As shown in FIGS. 5 and 6, a battery lock mechanism 30 is attached to the +Y-axis direction side of the slot stay 32. When the battery lock mechanism 30 is in the locked state, the battery lock mechanism 30 restricts the movement of the mobile battery 12 in the +Z-axis direction. As a result, the user cannot pull out the mobile battery 12 from the slot 14. When the battery lock mechanism 30 is in the unlocked state, the battery lock mechanism 30 allows the movement of the mobile battery 12 in the +Z-axis direction. As a result, the user can pull out the mobile battery 12 from the slot 14.

[0046] As shown in FIGS. 5 and 6, a slot guide 34 is attached to the +Z-axis direction side of the slot stay 32. The slot guide 34 has an insertion port 341. The insertion port 341 is a hole that penetrates the slot guide 34 in the Z-axis direction. When the slot guide 34 is viewed in the Z-axis direction, the insertion port 341 is substantially rectangular. The insertion port 341 is connected to the insertion port 321 of the slot stay 32.

[0047] As shown in FIGS. 5 and 6, a bottom cover 36 is attached to the opening 287 on the -Z-axis direction side of the slot body 29. The bottom cover 36 constitutes the bottom 29a of the slot body 29. As shown in FIG. 6, a connector unit 40, a fan 42, an electronic circuit board 44, and a detection switch 46 are attached to the bottom cover 36. With the connector unit 40, the fan 42, the electronic circuit board 44, and the detection switch 46 attached to the bottom cover 36, a bottom cover assembly 50 is constituted. The bottom cover assembly 50 will be described in detail later.

[0048] [Configuration of the door] As shown in FIG. 6, the door 38 is provided so as to be rotatable about a shaft 381. The shaft 381 is attached to the slot body 29. The shaft 381 extends in the X-axis direction. That is, the shaft 381 extends along a second direction that intersects the direction (Z-axis direction) in which the mobile battery 12 is inserted into and removed from the slot sleeve 26. The shaft 381 is disposed in the +Y-axis direction with respect to the mobile battery 12 housed in the slot sleeve 26. That is, the shaft 381 is disposed at a higher position than the mobile battery 12 housed in the slot sleeve 26. Thereby, when the mobile battery 12 is pulled out from the slot sleeve 26, the door 38 closes by its own weight. The shaft 381 corresponds to the rotating shaft of the present invention.

[0049] A torsion spring (not shown) provided on the shaft 381 biases the door 38 in a counterclockwise rotation direction about the shaft 381 when viewed from the -X axis direction. As a result, when the mobile battery 12 is pulled out from the slot sleeve 26, the door 38 is pushed in a closing direction by the torsion spring. When the mobile battery 12 is not housed in the slot sleeve 26, the door 38 is located at the first position. At this time, the closing amount of the insertion port 31c of the slot flange 31 by the door 38 is the largest.

[0050] When the door 38 is located at the first position, at least a part of the door 38 is arranged on the trajectory along which the mobile battery 12 is inserted into and removed from the slot sleeve 26. When the door 38 is arranged in this way, when the mobile battery 12 is inserted into the slot 14, the mobile battery 12 pushes open the door 38. That is, the door 38 rotates in an opening direction against the biasing force of the torsion spring. As a result, the door 38 opens the insertion port 31c of the slot flange 31. When the mobile battery 12 is housed in the slot sleeve 26, the door 38 is located at the second position. At this time, the closing amount of the insertion port 31c of the slot flange 31 by the door 38 is the smallest.

[0051] The door 38 is not limited to a door that opens and closes by rotating about the shaft 381. The door 38 may be a door that opens and closes by translating in the X-axis direction or the Y-axis direction.

[0052] As shown in FIG. 8, a roller 54 is provided on the side of the door 38 on the -Y axis direction side. The roller 54 is rotatably provided about the shaft 55.

[0053] As shown in FIG. 8, when the door 38 is open, the portion of the roller 54 on the +Z axis direction side closest to the slot body 29 is closer to the -Z axis direction than the portion of the door 38 on the -Z axis direction side closest to the slot body 29. That is, the distance between the portion of the roller 54 closest to the slot body 29 and the slot body 29 is smaller than the distance between the portion of the door 38 closest to the slot body 29 and the slot body 29.

[0054] [Configuration of the Slot Body] FIG. 8 is a cross-sectional view of the slot body 29, the door 38, and the mobile battery 12. FIG. 8 shows the state where the door 38 is open.

[0055] Figure As shown in FIG. 8, a door storage portion 57 is formed on the upper inner surface 221 located on the +Y-axis direction side of the slot body 29. The door storage portion 57 is recessed in a concave shape toward the +Y-axis direction. With the mobile battery 12 accommodated in the slot sleeve 26, the door 38 retracts into the door storage portion 57. The position of the door 38 at this time is the second position. With the door 38 retracted into the door storage portion 57, the roller 54 abuts against the side surface 12d of the mobile battery 12. Thereby, the friction between the mobile battery 12 inserted into and removed from the slot 14 and the door 38 can be reduced. The door storage portion 57 corresponds to the accommodation recess of the present invention.

[0056] As shown in FIGS. 8 and 9, a rubber seal 90 is provided in the door storage portion 57. Another accommodation recess 88 is continuously provided in the door storage portion 57. Alternatively, the rubber seal 90 is provided in this accommodation recess 88.

[0057] As shown in FIG. 9, the rubber seal 90 is provided on the upper inner surface 221 of the cylindrical portion 29b. The upper inner surface 221 is the surface facing vertically downward among the inner surfaces of the cylindrical portion 29b. And the upper inner surface 221 is located at the highest position among the inner surfaces of the cylindrical portion 29b. Therefore, the upper inner surface 221 corresponds to the first surface and the highest position surface of the present invention. The rubber seal 90 extends along the -Y-axis direction from the upper inner surface 221. Note that the -Y-axis direction faces vertically downward. That is, the extending direction of the rubber seal 90 is the direction toward the side surface 12d (the first curved surface portion) of the mobile battery 12.

[0058] As can be understood from this, when the mobile battery 12 is accommodated in the slot sleeve 26, the side surface 12d of the mobile battery 12 faces the upper inner surface 221 of the slot sleeve 26. Therefore, the upper inner surface 221 corresponds to the first surface of the present invention, and the side surface 12d corresponds to the second surface of the present invention.

[0059] The rubber seal 90 extends along a first direction and a second direction that intersect with respect to the insertion and extraction direction (Z-axis direction) of the mobile battery 12. In the rubber seal 90, the extension length along the first direction is smaller than the extension length along the second direction. In the first embodiment, the first direction is the Y-axis direction and the second direction is the X-axis direction. Thus, in the rubber seal 90, the extension length along the first direction (Y-axis direction) is short, and the extension length along the second direction (X-axis direction) is long. The extension length of the rubber seal 90 along the X-axis direction is preferably longer than half of the extension length of the mobile battery 12 along the X-axis direction. However, the extension length of the rubber seal 90 along the X-axis direction is preferably shorter than the extension length of the mobile battery 12 along the X-axis direction. Further, the extension length of the rubber seal 90 along the X-axis direction is preferably longer than the length of the connector 56 or the through hole 80 along the X-axis direction.

[0060] The rubber seal 90 is made of, for example, rubber. Therefore, the rubber seal 90 exhibits flexibility throughout. Accordingly, the longitudinal end portions (end portions in the X-axis direction) and the extension direction end portions (end portions in the Y-axis direction) of the rubber seal 90 are flexible portions 96 that exhibit flexibility. Among the flexible portions 96, the longitudinal end portion abuts against the X-axis direction end portion on the side surface 12d of the mobile battery 12. Among the flexible portions 96, the extension direction end portion abuts against the +Y-axis direction end portion on the side surface 12d.

[0061] As described above, the rubber seal 90 extends from the upper inner surface 221 toward the -Y-axis direction. Accordingly, the extension direction of the rubber seal 90 along the first direction is the -Y-axis direction. The extension end 92 of the rubber seal 90 is the end portion of the rubber seal 90 in the -Y-axis direction (first direction). In the first embodiment, the lower end portion of the rubber seal 90 corresponds to the end portion of the rubber seal 90 in the -Y-axis direction.

[0062] The extending end 92 of the rubber seal 90 is curved following the curvature of the side surface 12d (the first curved surface portion) of the mobile battery 12. That is, a curved portion 94 having a concave curved surface shape in the +Y-axis direction is formed on the extending end 92 of the rubber seal 90. Thus, the extending end 92 of the rubber seal 90 is formed as a second curved surface portion that is recessed in a concave shape toward the upper inner surface 221 (the first surface). In other words, the extending end 92 of the rubber seal 90 corresponds to the curvature of the side surface 12d and is curved in a concave shape toward the first surface. The end portion on the opposite side of the extending end 92 of the rubber seal 90 is closest to the upper inner surface 221 which is the first surface.

[0063] The lower end portion (extending end 92) of the rubber seal 90 abuts on a portion of the side surface 12d of the mobile battery 12 that is composed of the side surface of the bottom case 121. Therefore, the longitudinal end portions of the flexible portion 96 of the rubber seal 90 abut on the X-axis direction end portions of the side surface (side surface 12d) of the bottom case 121.

[0064] When the mobile battery 12 is inserted into the slot sleeve 26, the flexible portion 96 of the rubber seal 90 is pressed by the mobile battery 12 and flexes in the -Z-axis direction. For this reason, a sufficient seal is achieved between the extending end 92 of the rubber seal 90 and the side surface 12d of the mobile battery 12.

[0065] In this case, the entire rubber seal 90 is at a higher position than the through hole 80. Also, the distance from the rubber seal 90 to the insertion port 31c is smaller than the distance from the through hole 80 to the insertion port 31c. For this reason, the entire rubber seal 90 is closer to the insertion port 31c than the through hole 80.

[0066] As shown in FIG. 10, an indicator 58 is provided on a side plate 31a located in the -Y axis direction of the slot flange 31. The indicator 58 indicates the charging state of the mobile battery 12 housed in the slot 14. For example, when the mobile battery 12 is being charged, the indicator 58 lights up or blinks. When the charging of the mobile battery 12 is completed, the indicator 58 goes out. Alternatively, the display color of the indicator 58 when the mobile battery 12 is being charged may be made different from the display color of the indicator 58 when the charging of the mobile battery 12 is completed.

[0067] [Configuration of Bottom Cover Assembly] FIGS. 11 and 12 are perspective views of the slot 14. As shown in FIG. 11, a connector unit 40, a fan 42, an electronic circuit board 44, and a detection switch 46 (see FIG. 8) are provided on the bottom cover 36. Thereby, the bottom cover assembly 50 is configured. The bottom cover assembly 50 is fixed to the slot body 29. The fan 42 promotes the flow of air inside the slot sleeve 26.

[0068] The connector unit 40 has a connector 56 (male connector 56) shown in FIG. 12 and a motor 60. The male connector 56 has male electrical terminals for power transmission and reception and male communication terminals for communication signal transmission and reception. That is, the connector 56 serves as both an electrical terminal and a communication terminal. The male connector 56 may also be called a plug.

[0069] The connector 56 fits into the connector 28 of the mobile battery 12. At this time, power is supplied from the connector 56 to the mobile battery 12, and the mobile battery 12 is charged. Alternatively, the power of the mobile battery 12 is taken out through the connector 56, and the mobile battery 12 discharges. Further, through the connector 28 and the connector 56, the mobile battery 12 and a control device 18 (see FIG. 2) provided inside the battery exchanger 10 are communicably connected. That is, communication signals are transmitted and received between the mobile battery 12 and the control device 18.

[0070] The connector 56 moves forward or backward along the Z-axis direction by the motor 60. Specifically, the motor 60 has a rotating shaft (not shown). The rotating shaft extends from the motor 60 in the +Y-axis direction. A pinion 601 shown in FIG. 12 is attached to the tip of the rotating shaft. The pinion 601 meshes with a rack 602. The motor 60 is mechanically connected to the connector 56 via the pinion 601, the rack 602, and the base 48. The connector 56 and the motor 60 are attached to the bottom cover 36 via the base 48. Thereby, the motor 60 is supported by the bottom cover 36.

[0071] When viewed from the -Z-axis direction of the bottom cover 36, the detection switch 46, the fan 42, the base 48, the connector 56, the motor 60, the pinion 601, the rack 602, and the electronic circuit board 44 are arranged so as to be within the inner side of the outer edge of the bottom cover 36. That is, the detection switch 46, the fan 42, the base 48, the connector 56, the motor 60, the pinion 601, the rack 602, and the electronic circuit board 44 are arranged so as to be within the range of a projection parallel to the outer edge of the bottom cover 36. The parallel projection of the outer edge of the bottom cover 36 is a virtual area obtained by projecting the outer edge of the bottom cover 36 in the extending direction of the slot sleeve 26 (the insertion / removal direction of the mobile battery 12 or the Z-axis direction).

[0072] Thereby, when the bottom cover 36 is attached to the slot body 29, it is possible to prevent the detection switch 46, the fan 42, the base 48, the connector 56, the motor 60, the pinion 601, the rack 602, and the electronic circuit board 44 from interfering with surrounding members.

[0073] The electronic circuit board 44 (see FIG. 11) performs charge control of the mobile battery 12 housed in the slot sleeve 26, for example. A detection switch 46 is mounted on the electronic circuit of the electronic circuit board 44. When the mobile battery 12 is held in the slot sleeve 26, the detection switch 46 is pushed down by the mobile battery 12 and switches from off to on.

[0074] [Control of the Slot] When the motor 60 is driven, the connector 56 moves in the Z-axis direction. When the detection switch 46 switches from off to on, the detection switch 46 detects that the mobile battery 12 is held by the slot sleeve 26. In this case, the motor 60 moves the connector 56 in the +Z-axis direction to bring the connector 56 closer to the connector 28 of the mobile battery 12.

[0075] When the detection switch 46 switches from on to off, the detection switch 46 detects that the mobile battery 12 has been removed from the slot sleeve 26. In this case, the motor 60 moves the connector 56 in the -Z-axis direction to move the connector 56 away from the connector 28 of the mobile battery 12.

[0076] When the detection switch 46 is off, the detection switch 46 does not detect that the mobile battery 12 is held by the slot sleeve 26. In this case, the motor 60 does not move the connector 56 in the +Z-axis direction and does not bring the connector 56 closer to the connector 28 of the mobile battery 12.

[0077] In the connector unit 40 according to the first embodiment, when the motor 60 is driven, the connector 56 is moved from the disconnection position to the connection position with the connector 28. Or, when the motor 60 is driven, the connector 56 is moved from the connection position to the disconnection position.

[0078] FIG. 13A shows the state when the connector 56 is located at the disconnection position. When the connector 56 is located at the disconnection position, as shown in FIG. 13A, the tip of the connector 56 is positioned closer to the -Z-axis direction from the bottom cover 36.

[0079] FIG. 13B shows a state where the connector 56 has moved in the +Z-axis direction from the disconnection position. As shown in FIG. 13B, when the connector 56 moves in the +Z-axis direction from the disconnection position, the tip of the connector 56 passes through the through hole 80 of the bottom cover 36. The tip of the connector 56 that has passed through the through hole 80 is inserted into the connector 28 of the mobile battery 12.

[0080] FIG. 13C shows a state when the connector 56 is in the connection position. As shown in FIG. 13C, when the connector 56 is in the connection position, the connection between the connector 56 and the connector 28 of the mobile battery 12 is completed.

[0081] The battery exchanger 10 according to the first embodiment is basically configured as described above. Next, the operation and effects of the battery exchanger 10 will be described.

[0082] When the user replaces the mobile battery 12, the user holds the handle 24 (mainly the first gripping portion 241) of the mobile battery 12 housed in the slot 14 of the battery exchanger 10 with one hand as described above. At this time, the user selects the fully charged mobile battery 12. The user can confirm whether the mobile battery 12 is being charged or fully charged by the indicator 58.

[0083] Note that when the mobile battery 12 is housed in the slot 14, the door 38 is in the second position (see FIG. 6). For this reason, the opening 286 of the slot body 29 is open. Therefore, the user can visually recognize the handle 24 from the insertion port 31c.

[0084] Also, when the mobile battery 12 is housed in the slot 14, the extending end 92 (lower end portion) of the rubber seal 90 is in contact with the bottom case 121 of the mobile battery 12. By this contact, the space between the side surface 12d of the mobile battery 12 and the upper inner surface 221 of the upper side plate 26b is sealed.

[0085] After that, the user applies a tensile force to the mobile battery 12. Along with this, the battery lock mechanism 30 becomes unlocked. Also, the motor 60 is driven in the connector unit 40. As a result, the connector 56 moves from the connection position with the connector 28 to the disconnection position. Therefore, the user can easily pull out the mobile battery 12 from the slot 14. Note that the connector 56 passes through the through hole 80 during the process of moving from the connection position to the disconnection position.

[0086] As the mobile battery 12 is pulled out from the slot 14, the bottom case 121 makes sliding contact with the extending end 92 of the rubber seal 90. As described above, in the rubber seal 90, the end portion in contact with the bottom case 121 is the flexible portion 96. For this reason, when the bottom case 121 makes sliding contact with the extending end 92 of the rubber seal 90, the rubber seal 90 easily bends. Therefore, damage to the rubber seal 90 is avoided. Also, damage to the bottom case 121 is avoided. Furthermore, since the pulling resistance by the rubber seal 90 is small, it is not necessary to increase the tensile force applied to the mobile battery 12.

[0087] When the bottom surface 12a of the mobile battery 12 passes through the door 38 as the mobile battery 12 is pulled out from the slot 14, the door 38 rotates about the shaft 381. As a result, the door 38 moves from the second position to the first position. Therefore, the opening 286 of the slot body 29 is closed.

[0088] Next, the user holds the handle 24 of the mobile battery 12 with a reduced SOC in one hand. After that, the user lifts the mobile battery 12. Further, the user places the other hand, for example, against the bottom case 121 to make the mobile battery 12 in an inclined posture. At this time, in the mobile battery 12, the bottom case 121 is in a low position and the top case 123 is in a high position. The user inserts the bottom case 121 of the inclined mobile battery 12 into the insertion port 31c of the slot flange 31.

[0089] In this state, the user pushes in the mobile battery 12. As a result, the mobile battery 12 moves toward the bottom inner surface 231. When the bottom case 121 pushes the door 38 during this movement, the door 38 rotates about the shaft 381. That is, the door 38 moves from the first position to the second position.

[0090] Also, the bottom case 121 starts to slide in contact with the extending end 92 of the rubber seal 90. Similar to the above, the rubber seal 90 bends at this time. Therefore, damage to the rubber seal 90 is avoided. Also, damage to the bottom case 121 is avoided. Furthermore, it is not necessary to increase the pushing force applied to the mobile battery 12.

[0091] When it is detected that the bottom case 121 has stopped by the bottom inner surface 231, the battery lock mechanism 30 enters the locked state. Also, the motor 60 is driven in the connector unit 40. As a result, the connector 56 moves from the disconnection position to the connection position with the connector 28. Consequently, the connector 56 fits into the connector 28. Thereafter, charging of the mobile battery 12 is started. Note that the connector 56 passes through the through hole 80 in the process of moving from the disconnection position to the connection position.

[0092] Incidentally, the battery exchanger 10 may be installed outdoors. In this case, there is a possibility that the mobile battery 12 is exchanged as described above during rainfall. The slot 14 has an inclined posture in which the insertion port 31c faces vertically upward rather than horizontally. For this reason, rainwater may enter the slot 14 from the insertion port 31c. When such a situation occurs, it is assumed that the rainwater moves along the side surface 12d of the mobile battery 12 toward the connector 28 and the connector 56.

[0093] Here, in the first embodiment, the side surface 12d of the mobile battery 12 is a first curved surface portion that is convexly curved. Therefore, as indicated by the arrow A in FIG. 9, when rainwater is flowing along the side surface 12d, it flows toward the side surface 12e or the side surface 12f due to gravity. For this reason, it is possible to suppress the rainwater from reaching the connector 28 and the connector 56.

[0094] Even if, by any chance, the rainwater further flows toward the connector 28 and the connector 56, the rainwater is blocked by the rubber seal 90. In this case, since the extending end 92 of the rubber seal 90 is in contact with the bottom case 121, the space between the upper inner surface 221 and the side surface 12d is sealed. Therefore, the path of the rainwater blocked by the rubber seal 90 is changed to be directed toward the side surface 12e or the side surface 12f. For this reason, it is further possible to suppress the rainwater from reaching the connector 28 and the connector 56.

[0095] Note that, for example, when the mobile battery 12 is not inserted into the slot 14, the connector 56 is located in the -Z axis direction with respect to the through hole 80. That is, the connector 56 is not exposed inside the slot 14. In this case, it is possible to suppress the rainwater from reaching the through hole 80.

[0096] As described above, in the first embodiment, the rubber seal 90 is provided inside the slot 14. Thereby, it is possible to prevent the rainwater from reaching the connector 28 and the connector 56. In other words, the rubber seal 90 provided inside the slot 14 can protect the connector 28 and the connector 56 from the rainwater. The rainwater that has flowed along the side surface 12e or the side surface 12f of the mobile battery 12 is discharged, for example, through the drain hole 69 to the external space of the slot body 29.

[0097] In the first embodiment, the installation position of the rubber seal 90 is not limited to the upper inner surface 221. That is, it is also possible to set the installation position of the rubber seal 90 to the left inner surface 222, the right inner surface 223, or the lower inner surface 220.

[0098] Next, the second embodiment will be described with reference to FIGS. 14 and 15. Note that the same components as those in the first embodiment are denoted by the same reference numerals, and detailed descriptions of these components may be omitted.

[0099] In the second embodiment shown in FIG. 14, the slot 400 has a slot body 402. The slot body 402 is a bottomed cylindrical shape having a bottom 404 and a cylindrical portion 406. A bottom cover 408 is attached to the opening on the -Z-axis direction side of the cylindrical portion 406. The bottom cover 408 constitutes the bottom 404.

[0100] The bottom cover 408 has a bottom inner surface 410. The bottom inner surface 410 is one of the inner surfaces of the slot body 402. When the mobile battery 12 is inserted into the slot body 402, the bottom inner surface 410 faces the bottom surface 12a of the mobile battery 12.

[0101] As shown in FIG. 15, a first protrusion 412a and a second protrusion 412b are provided on the bottom inner surface 410 of the bottom cover 408. The first protrusion 412a and the second protrusion 412b protrude in the +Z-axis direction from the bottom inner surface 410. The height positions of the first protrusion 412a and the second protrusion 412b in the Y-axis direction are substantially the same. The first protrusion 412a is closer to the -X-axis direction, and the second protrusion 412b is closer to the +X-axis direction. Thereby, a clearance 413 is formed between the first protrusion 412a and the second protrusion 412b.

[0102] In this case, the rubber seal 414 is joined to the first protrusion 412a and the second protrusion 412b, for example, via mechanical joining or an adhesive. The rubber seal 414 extends in the -Y axis direction from the +Y side ends of the first protrusion 412a and the second protrusion 412b in the Y axis direction which is the first direction. In the rubber seal 414, the lower end which is the end in the -Y axis direction is the extending end 415 as in the first embodiment. The extending end 415 protrudes slightly in the -Y axis direction from the -Y side ends of the first protrusion 412a and the second protrusion 412b. Also, the rubber seal 414 extends from the -X side end of the first protrusion 412a to the +X side end of the second protrusion 412b in the X axis direction which is the second direction. Although not particularly shown, the rubber seal 414 may be provided with a filling portion that is inserted into the clearance 413 and fills the clearance 413.

[0103] Thus, also in the second embodiment, the rubber seal 414 extends along the Y axis direction (first direction) and the X axis direction (second direction) that intersect with the insertion / removal direction (Z axis direction) of the mobile battery 12. In the rubber seal 414, the extending length along the first direction is smaller than the extending length along the second direction. The extending length of the rubber seal 414 along the X axis direction is preferably longer than half of the extending length of the mobile battery 12 along the X axis direction. However, the extending length of the rubber seal 414 along the X axis direction is preferably shorter than the extending length of the mobile battery 12 along the X axis direction. Further, the extending length of the rubber seal 414 along the X axis direction is preferably longer than the length along the X axis direction in the connector 56 or the through hole 80.

[0104] In FIG. 14, the upper end surface of the rubber seal 414 is separated from the upper inner surface 221 of the slot body 402. However, the upper end surface of the rubber seal 414 may contact the upper inner surface 221.

[0105] As shown in FIG. 14, a door 416 is attached to the slot base 32. The door 416 is provided to be rotatable about the shaft 381. When the mobile battery 12 is not inserted into the slot 14, the door 416 is closed. At this time, the door 416 closes the opening on the +Z-axis direction side of the slot body 402. When the mobile battery 12 is inserted into the slot 14, the door 416 is pushed in the -Z-axis direction by the mobile battery 12. As a result, the door 416 rotates about the shaft 381 and opens. At this time, the door 416 opens the opening on the +Z-axis direction side of the slot body 402.

[0106] When the door 416 is open, the -Z-axis side end of the door 416 faces substantially opposite the rubber seal 414. In this state, the -Z-axis side end of the door 416 and the rubber seal 414 are separated from each other.

[0107] The extending end 415 of the rubber seal 414 is curved following the curvature of the side surface 12d (first curved surface portion) of the mobile battery 12. That is, a curved portion 418 that is a curved surface concave in the +Y-axis direction is formed at the lower end portion (extending end 415) of the rubber seal 414. In this way, the extending end 415 of the rubber seal 414 is formed as a second curved surface portion that is recessed in a concave shape toward the upper inner surface 221 (first surface) of the slot body 402. In other words, the extending end 415 of the rubber seal 414 corresponds to the curvature of the side surface 12d and is curved in a concave shape toward the upper inner surface 221 which is the first surface.

[0108] The extending end 415 of the rubber seal 414 abuts on the portion of the side surface 12d of the mobile battery 12 that is composed of the side surface of the bottom case 121. Therefore, the longitudinal end portions of the flexible portion 420 of the rubber seal 414 abut on the X-axis direction end portions of the side surface (side surface 12d) of the bottom case 121. The extending direction end portions of the flexible portion 420 abut on the +Y-axis direction end portions of the side surface 12d.

[0109] When the mobile battery 12 is inserted into the slot 400, the flexible portion 420 of the rubber seal 414 is pressed against the mobile battery 12 and flexes in the -Z axis direction. Therefore, a sufficient seal is achieved between the extending end 415 of the rubber seal 414 and the side surface 12d of the mobile battery 12. Accordingly, also in the second embodiment, it is possible to prevent rainwater or the like from reaching the connectors 28 and 56. In other words, the rubber seal 414 provided inside the slot 400 can protect the connectors 28 and 56 from rainwater. When the connector 56 is located in the -Z axis direction with respect to the through hole 80, it is possible to suppress rainwater from reaching the through hole 80.

[0110] As the mobile battery 12 is pulled out from the slot 400, the bottom case 121 comes into sliding contact with the extending end 415 of the rubber seal 414. Similar to the first embodiment, in the rubber seal 414, the end portion in contact with the bottom case 121 is the flexible portion 420. Therefore, when the bottom case 121 comes into sliding contact with the extending end 415 of the rubber seal 414, the rubber seal 414 easily flexes. Accordingly, it is possible to avoid damage to the rubber seal 414. Also, it is possible to avoid damage to the bottom case 121. Further, since the pulling resistance by the rubber seal 414 is small, it is not necessary to increase the tensile force applied to the mobile battery 12.

[0111] As described above, also in the second embodiment, the same effects as those of the first embodiment can be obtained.

[0112] In the second embodiment, the positions of the first protruding portion 412a and the second protruding portion 412b (the installation position of the rubber seal 414) are not limited to the +Y axis direction of the bottom inner surface 410. That is, it is also possible to set the installation position of the rubber seal 414 in the -Y axis direction of the bottom inner surface 410, the +X axis direction of the bottom inner surface 410, or the -X axis direction of the bottom inner surface 410.

[0113] In the above-described first and second embodiments, the connector 56 is provided so as to be movable back and forth. Alternatively, as shown in FIG. 16, the connector 56 may be positioned and fixed to the bottom inner surface 231 (or the bottom inner surface 410).

[0114] The electric device is not limited to the mobile battery 12. For example, a power feeder that removably houses the mobile battery 12 may be configured to be accommodated in the slot 14.

[0115] The housing device is not limited to the battery exchanger 10. Another example of the housing device is a device that inputs power to the mobile battery 12. Specifically, it is a charging device or a charge-discharge device, etc. The charging device or the charge-discharge device, etc. may be a movable portable type or a stationary type.

[0116] The housing device may be a device that outputs power from the mobile battery 12. Examples of such a housing device include moving bodies such as electric vehicles, outboard motors, or aircraft. Electric vehicles include passenger vehicles such as motorcycles, three-wheeled vehicles, or four-wheeled vehicles. Electric vehicles also include work vehicles such as lawn mowers, transport carts, or snow removal machines. Aircraft include drones or airplanes. An outboard motor is a propulsion device used for ships.

[0117] Another example of a housing device that outputs power is a power feeder that uses the mobile battery 12 as a power source. The power feeder may be a movable portable type or a stationary type.

[0118] Note that the present invention is not limited to the above-described disclosure, and various configurations can be adopted without departing from the gist of the present invention.
