Description

[Technical Field]

[0001] The present invention relates to a storage device. [Background technology]

[0002] BACKGROUND ART Conventionally, storage devices that charge storage batteries when they are stored are known (see, for example, Patent Documents 1 and 2). Patent Document 1 describes a configuration in which a mobile battery serving as a storage battery is detachably mounted on a movable container-shaped battery tray. The battery tray described in Patent Document 1 has a flat bottom, is inclined when mounted, and is horizontal when charging. The battery tray in Patent Document 1 is provided with drainage holes on the side of the battery tray, and discloses a configuration in which water can be drained when the battery tray is tilted. Patent Document 2 discloses a storage device in which a throttle module into which a battery is inserted and removed is inclined relative to the horizontal. In Patent Document 2, drainage holes are provided in the lower side of the approximately cylindrical slot and in the bottom cover that covers one end of the slot. The inner surface of the bottom cover in Patent Document 2 is formed flat. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] International Publication No. 2021 / 049622 [Patent Document 2] International Publication No. 2022 / 075430 Summary of the Invention [Problem to be solved by the invention]

[0004] In the storage devices described in Patent Documents 1 and 2, the rear end of the battery in the insertion direction is configured to abut against the flat bottom surface of the slot, making it difficult for a gap to form between the rear end of the battery in the insertion direction and the bottom surface of the slot. Therefore, if water flows onto the bottom surface, there is a risk that the water will remain on the bottom surface. The present invention has been made in consideration of the above-mentioned circumstances, and aims to provide a storage device that can easily prevent water from accumulating on the bottom surface of the storage section. [Means for solving the problem]

[0005] The storage device is characterized in that it has a storage section in which a storage battery is detachably stored, and the bottom surface of the storage section has a support section that contacts the storage battery when the storage battery is stored therein, and a non-support section that has a height difference along a predetermined direction and does not contact the storage battery. [Effects of the Invention]

[0006] A storage device can be provided that can easily prevent water from accumulating on the bottom surface of the storage section. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0008] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will now be described with reference to the accompanying drawings, in which the symbol FR indicates the front, the symbol UP indicates the upper side, and the symbol LH indicates the left side.

[0009] [Embodiment Mode] FIG. 1 is an exploded perspective view of a storage device 1 according to an embodiment. The storage device 1 is a device for storing a battery (storage battery) 2 formed in a generally rectangular parallelepiped shape. The storage device 1 is configured to allow the battery 2 to be charged during storage. The storage device 1 has a plurality of storage slots (storage sections) 3 for detachably storing the batteries 2, a mounting frame 4 to which the plurality of storage slots 3 are fixed, and a housing 5 for accommodating the plurality of storage slots 3 and the mounting frame 4. The battery 2 has a grip section 2b on one side of the generally rectangular parallelepiped shape and a battery terminal 2a (see FIG. 7) on the other side of the generally rectangular parallelepiped shape. The battery 2 can be carried by the user and is configured to be detachably attached to, for example, an electric vehicle (four-wheeled vehicle, three-wheeled vehicle, two-wheeled vehicle), a lawnmower, agricultural machine, or other work machine. The battery 2 is a mobile power pack (MPP).

[0010] The storage device 1 of this embodiment can be placed horizontally, with the storage slots 3 lined up in the left-right direction, or vertically, with the storage slots 3 lined up in the up-down direction. Unless otherwise specified, the storage device 1 in horizontal orientation will be described below.

[0011] The mounting frame 4 has a frame structure 10 that is framed in a rectangular parallelepiped shape and extends in the left-right direction (the direction in which the receiving slots 3 are arranged). More specifically, the frame structure 10 has four square pipe-shaped connection frames 11 that extend in the up-down direction (the insertion / removal direction). Rectangular frames 12, 13 are fixed to both the top and bottom ends of the connection frame 11. The rectangular frames 12, 13 are composed of two square pipe-shaped longitudinal frames 12a, 13a that extend in the left-right direction and two square pipe-shaped short frames 12b, 13b that extend in the front-rear direction.

[0012] The upper rectangular frame 12 is fixed to the upper end of the connecting frame 11 . The lower rectangular frame 13 is fixed to the connection frame 11 at a position shifted upward from the lower end of the connection frame 11. The frame structure 10 of this embodiment is made up of four connection frames 11, an upper rectangular frame 12, and a lower rectangular frame 13. Other frames may be added to the frame structure 10.

[0013] FIG. 2 is a front view showing the lower end portion of the storage device 1 according to the embodiment. A mounting panel (mounting member) 20, which is a rectangular plate having a thickness in the vertical direction, is fixed to the upper rectangular frame 12. The mounting panel 20 is made of a metal plate. Slot placement openings 20a are formed in the mounting panel 20, penetrating the panel in the thickness direction according to the placement positions of the storage slots 3. Storage slots 3 are fixed to the mounting panel 20 in correspondence with the slot placement openings 20a.

[0014] A rectangular electrical panel 21 having a thickness in the vertical direction is fixed to the lower rectangular frame 13. The electrical panel 21 is made of a metal plate. A central partition plate (partition member) 22 having a thickness in the horizontal direction is arranged between the mounting panel 20 and the electrical panel 21. The central partition plate 22 divides the space surrounded by the mounting panel 20 and the electrical panel 21 into left and right sections. Rectangular partition panels 23 having a thickness in the vertical direction are arranged on both the left and right sides of the central partition plate 22. The partition panels 23 are fixed to the mounting frame 4. The space between the partition panel 23 and the central partition plate 22 is sealed.

[0015] A pair of electrical equipment spaces (spaces) S1 and S2 are formed by the space surrounded by the bulkhead panel 23, the electrical equipment panel 21, and the central partition plate 22. Various electrical equipment such as a power supply unit (internal equipment) 30, a control board, and a communication unit are arranged in the electrical equipment spaces S1 and S2. The power supply unit 30 in this embodiment has an inverter.

[0016] As shown in FIG. 1, the mounting frame 4 and the receiving slot 3 are surrounded by four exterior panels 41, 42, 43, and 44. The front and rear exterior panels 41, 42 are formed in the same substantially rectangular plate shape, that is, the front and rear exterior panels 41, 42 have sides corresponding to the lengths of the longitudinal frames 12a, 13a and sides corresponding to the length from the electrical panel 21 to the upper end of the accommodating slot 3.

[0017] The left and right exterior panels 43, 44 are formed in the same substantially rectangular plate shape, that is, the left and right exterior panels 43, 44 have sides corresponding to the lengths of the short frames 12b, 13b and sides corresponding to the length from the electrical panel 21 to the upper end of the accommodating slot 3.

[0018] Each exterior panel 41 to 44 is fixed to the mounting frame 4. At this time, the gap between each exterior panel 41 to 44 and the partition wall panel 24 is sealed. Therefore, even if water may enter the upper surface of the partition wall panel 24, the partition wall panel 24 prevents the water from entering the electrical component spaces S1 and S2.

[0019] A block-shaped battery guide (insertion guide member) 45 is disposed above the exterior panels 41 to 44. The battery guide 45 is, for example, a single resin molded part. The battery guide 45 has a lower surface 45a and an upper surface 45b. The lower surface 45a is formed in a flat shape perpendicular to the insertion / removal direction. That is, in a horizontally placed storage device 1, the lower surface 45a forms a horizontal plane. The upper surface 45b slopes upward from the front to the rear. The battery guide 45 is formed with insertion openings 45c that communicate with the storage slots 3 corresponding to each storage slot 3. The lower surface 45a of the battery guide 45 is fixed to the upper end of the storage slot 3. The four exterior panels 41 to 44 and the battery guide 45 constitute the housing 5 of this embodiment.

[0020] An indicator 46 that indicates the charging state of the battery 2 is provided on the upper surface 45b of the battery guide 45. Also, a short-range wireless communication unit 47 that authenticates the user is provided on the upper surface 45b of the battery guide 45. The display unit 46 is, for example, an indicator. The display unit 46 is connected to the control device via wiring (not shown). The display unit 46 has, for example, an indicator for each storage slot 3. The display unit 46 notifies the user whether the battery 2 stored in the storage slot 3 has been charged or not by lighting or blinking the indicator. The short-range wireless communication unit 47 is connected to the control device via wiring (not shown). For example, an electronic terminal or an ID card is held over the short-range wireless communication unit 47, which performs short-range wireless communication with the electronic terminal or ID card to authenticate the user. If the user is authenticated, the control device may, for example, permit removal of the battery 2 housed in the housing slot 3.

[0021] 2, the electrical panel 21 in the storage device 1 is formed with vents 21a, 21b, 21c, and 21d that penetrate through the electrical panel 21 in the thickness direction. The vents 21a, 21b, 21c, and 21d are formed at both left and right ends of each of the electrical component spaces S1 and S2. That is, the vents 21a, 21b, 21c, and 21d are formed in a total of four locations: two locations at both longitudinal ends of the electrical panel 21 and two locations in the middle of the electrical panel 21 in the longitudinal direction.

[0022] In the electrical equipment space S1, the power supply unit 30 is disposed between the air vent 21a and the air vent 21b. An end fan arrangement space S1a is provided between the air vent 21a and the power supply unit 30. A central fan arrangement space S1b is provided between the air vent 21b and the power supply unit 30. Thus, two fan arrangement spaces S1a and S1b are provided in the electrical equipment space S1. In this embodiment, a cooling fan 35 is disposed in one of the two fan arrangement spaces S1a and S1b. The cooling fan 35 is a cooling fan 35 that can be driven to generate an airflow A11 from the central air vent 21b to the end air vent 21a. In other words, the air vent 21b is an intake port, and the air vent 21a is an exhaust port. The cooling fan 35 is controlled by a control device.

[0023] In the electrical equipment space S2, the power supply unit 30 is disposed between the air vent 21c and the air vent 21d. A central fan arrangement space S2a is provided between the air vent 21c and the power supply unit 30. An end fan arrangement space S2b is provided between the air vent 21d and the power supply unit 30. Thus, two fan arrangement spaces S2a and S2b are provided in the electrical equipment space S2. In this embodiment, a cooling fan 35 is disposed in one of the two fan arrangement spaces S2a and S2b. The cooling fan 35 is a cooling fan 35 that can be driven to generate an airflow A12 from the central air vent 21c to the end air vent 21d. In other words, the air vent 21c is an intake port. The air vent 21d is an exhaust port. The cooling fan 35 is controlled by a control device.

[0024] 3 is a perspective view of the receiving slot 3. FIG. 4 is a cross-sectional view of the receiving slot 3. The storage slot 3 has a slot portion 50 in which the battery 2 is accommodated so as to be insertable and removable, a connector unit 60 supported on the lower side of the slot portion 50 (one side in the insertion / removal direction), and a locking mechanism 70 supported on the upper side of the slot portion 50 (the other side in the insertion / removal direction).

[0025] The slot portion 50 has a slot case 51 in the shape of a substantially rectangular cylinder. The slot case 51 is an extrusion molded product made of metal. In this embodiment, the slot case 51 is an extrusion molded product made of aluminum.

[0026] A rectangular insertion-side panel 52 having a thickness in the vertical direction (insertion / removal direction) is fixed to the upper end of the slot case 51. The insertion-side panel 52 is a rectangular plate that is larger on the outer circumferential side than the cylindrical opening of the slot case 51. An opening 52a having a size corresponding to the shape of the opening at the upper end of the slot case 51 is formed in the insertion-side panel 52.

[0027] A rectangular fixed panel (peripheral protrusion) 53 having a thickness in the vertical direction is fixed to the lower end of the slot case 51. The fixed panel 53 is a rectangular plate that is larger on the outer periphery than the cylindrical opening of the slot case 51. Flange portions 53a that are folded upward are formed on both the left and right ends of the fixed panel 53. The flange portions 53a increase the rigidity of the fixed panel 53.

[0028] Here, the accommodating slots 3 are placed side by side in the left-right direction on the mounting surface 20b of the mounting panel 20 with the openings 52a facing upward. Then, for each accommodating slot 3, a fixing panel 53 is fixed to the mounting surface 20b of the mounting panel 20. The fixing panel 53 and the mounting panel 20 are fastened together by fastening members 100 that penetrate in the vertical direction (thickness direction). The fastening members 100 are, for example, bolts. Thus, the accommodating slots 3 are fixed so that the insertion and removal direction is vertical.

[0029] In this embodiment, the insertion-side panel 52 is fixed to the battery guide 45. In this embodiment, the insertion-side panel 52 is fastened with fastening members 100 that penetrate the insertion-side panel 52 in the thickness direction. Therefore, the storage slot 3 is fixed on both sides in the insertion / removal direction. Since the storage slot 3 is fixed on both sides in the longitudinal direction, it is firmly fixed. Furthermore, the various parts of the storage device 1 are connected via the slot case 51, which is a metal extrusion molded product, and this makes it easier to ensure the rigidity of the storage device 1.

[0030] In a region corresponding to the inside of the slot case 51 of the receiving slot 3, the fixed panel 53 is formed with a terminal opening 53b penetrating in the thickness direction. The terminal opening 53b extends in the left-right direction. A through-hole-shaped switch insertion opening 53c is formed in front of the terminal opening 53b. A drain opening 53d penetrating in the thickness direction is formed in front of the switch insertion opening 53c. The drain opening 53d extends in the left-right direction. The drain opening 53d is adjacent to the front inner surface 51a of the slot case 51 (see FIG. 4). The drain opening 53d extends along the front inner surface 51a of the slot case 51.

[0031] A connector unit 60 is supported on the underside of the fixed panel 53. The connector unit 60 has a housing 61. A slider 62 is supported on the housing 61. The slider 62 is supported so as to be slidable in the insertion / removal direction. A connector terminal (connecting member) 63 is fixed to the slider 62. The connector terminal 63 is movable integrally with the slider 62. Specifically, the connector terminal 63 is configured to be movable between a connection position where it penetrates the terminal port 53b and enters the slot case 51, and a connection release position where it is recessed in the terminal port 53b and retracted from the slot case 51. Power is supplied to the connector terminal 63 from the corresponding power supply device 30.

[0032] The slider 62 supports rack teeth 64 extending in the vertical direction. A gear 65 meshes with the rack teeth 64. The gear 65 is fixed to a drive shaft 66a of an electric motor 66. The electric motor 66 is disposed so that the drive shaft 66a is perpendicular to the insertion / removal direction. In this embodiment, the drive shaft 66a of the electric motor 66 extends in the front-rear direction. The electric motor 66 is fixed to the housing 61. The electric motor 66 is configured to be capable of driving forward and backward. The electric motor 66 is electrically connected to an electronic circuit board 67 supported by the fixed panel 53. The electric motor 66 is controlled by the electronic circuit board 67.

[0033] An electronic circuit is formed on the electronic circuit board 67. A control unit, a memory unit, and many other electronic and electrical devices are mounted on the electronic circuit of the electronic circuit board 67. The control unit of the electronic circuit board 67 controls charging of the battery 2 housed in the slot unit 50. The control unit of the electronic circuit board 67 is realized by, for example, a processing circuit. This processing circuit is configured by, for example, an integrated circuit such as an ASIC (Application Specific Integrated Circuit) or an FPGA (Field-Programmable Gate Array). The processing circuit may also be configured by an electronic circuit including discrete devices.

[0034] The processing circuit may be configured by a processor such as a CPU (Central Processing Unit) or a GPU (Graphics Processing Unit). In this case, the processing circuit is realized by executing a program stored in a storage unit in the processor.

[0035] A detection switch 68 is electrically connected to the electronic circuit board 67. The detection switch 68 detects whether or not a battery 2 has been accommodated in the accommodating slot 3. The detection switch 68 of this embodiment is a momentary switch configured so that a detector 68a can move back and forth in the insertion / removal direction. The detection switch 68 is inserted into the switch insertion opening 53c and is positioned with the detector 68a inserted into the slot case 51. The detector 68a is pressed by the battery 2 inserted in the accommodating slot 3, and the detection switch 68 detects that the battery 2 has been accommodated.

[0036] When the detection switch 68 detects the battery 2, the electronic circuit board 67 drives the electric motor 66. This causes the slider 62 to rise via the gear 65 and the rack teeth 64, and the connector terminal 63 moves to the connection position. At this time, the connector terminal 63 is inserted into the battery terminal 2a (see FIG. 7) of the battery 2, and the connector terminal 63 and the battery terminal 2a are electrically connected. Therefore, the battery 2 in the storage slot 3 can be charged.

[0037] Furthermore, when the electronic circuit board 67 reversely drives the electric motor 66, the slider 62 descends via the gear 65 and the rack teeth 64, and the connector terminal 63 moves to the disconnection position. At this time, the connector terminal 63 is pulled out of the battery terminal 2a and moves downward below the terminal opening 53b. In other words, the electrical connection between the connector terminal 63 and the battery terminal 2a is released.

[0038] A locking mechanism 70 is supported on the insertion-side panel 52 of the slot portion 50. The locking mechanism 70 has a housing 71. The housing 71 is fixed to the rear of the insertion-side panel 52. A locking member 72 is supported on the housing 71 so as to be slidable in the front-rear direction. That is, when viewed in the insertion / removal direction, the locking member 72 is supported so as to be movable between a locked position where it overlaps with the opening 52a and an unlocked position where it is retracted from the opening 52a. A cam pin 73 extending in the left-right direction is fixed to the locking member 72. The cam pin 73 engages with a cam groove 74a of a cam groove forming member 74. The cam groove 74a is inclined forward as it extends downward. The cam groove forming member 74 is, for example, a pair of left and right plate members.

[0039] The cam groove forming member 74 is fixed to the upper end of a rod 75 that extends in the vertical direction. The rod 75 has a lower end fixed to the slider 62. Therefore, the rod 75 moves up and down as the slider 62 moves up and down. That is, when the slider 62 moves up, the rod 75 and the cam groove forming member 74 move up. At this time, the cam pin 73 moves forward while being guided by the cam groove 74a, so the locking member 72 moves to the locked position. Furthermore, when the slider 62 moves down, the rod 75 and the cam groove forming member 74 move down. At this time, the cam pin 73 moves rearward while being guided by the cam groove 74a, so the locking member 72 moves to the unlocked position. Therefore, when the connector terminal 63 is connected to the battery terminal 2 a, the locking member 72 is moved to the locking position, and the battery 2 is prevented from being removed from the housing slot 3 .

[0040] 5 is a perspective view showing the periphery of the bottom member 54 of the receiving slot 3. FIG. 6 is a view corresponding to the perspective view of FIG. A bottom member (bottom surface) 54 is disposed on the upper surface of the fixed panel 53. The bottom member 54 is formed from a material capable of absorbing impact. In this embodiment, the bottom member 54 is made of rubber as an elastic member. The bottom member 54 is formed in the shape of a substantially rectangular plate. The bottom member 54 is formed with a bottom upper surface (non-support portion) 54a that slopes downward from the rear to the front.

[0041] The front end of the bottom member 54 has a drain opening (drain port) 54d cut out in a generally U-shape at the rear. Support portions 54e, 54f, and 54g that protrude above the bottom upper surface 54a are formed at the rear, left, and right ends of the bottom member 54. The support portions 54e to 54g slope upward from the center of the surface of the bottom member 54 toward the outer periphery. The support portions 54e to 54g can support the battery 2 by abutting the lower end (rear end in the insertion direction) of the battery 2 at the center of the surface. Furthermore, the support portions 54e to 54g can support the battery 2 by abutting the outer peripheral side surface of the battery 2 at the outer periphery of the surface.

[0042] A terminal opening (second opening) 54b extending in the left-right direction is formed in front of the support portion 54e at the rear end. The terminal opening 54b is close to the support portion 54e at the rear end. The terminal opening 54b is formed at a position and with a size corresponding to the terminal opening 53b of the fixed panel 53. The terminal opening 54b communicates with the terminal opening 53b of the fixed panel 53. A bank portion (wall portion) 54h is formed around the terminal opening 53b, protruding above the bottom upper surface 54a. The bank portion 54h is formed around the entire periphery of the terminal opening 53b so as to frame the terminal opening 53b. The bank portion 54h is formed lower than the center of the surfaces of the support portions 54e to 54g.

[0043] A through-hole-shaped switch insertion opening 54c is formed in front of the terminal opening 54b. The switch insertion opening 54c is formed at a position and with a size corresponding to the switch insertion opening 54c of the fixed panel 53. The switch insertion opening 54c communicates with the switch insertion opening 54c of the fixed panel 53.

[0044] In the inner region surrounded by the support portions 54e to 54g, a plurality of protrusions (support portions) 54i extending along the inclination direction of the bottom surface 54a are formed. The protrusions 54i protrude upward from the bottom surface 54a. The protrusions 54i are formed at the same height as the center of the surfaces of the support portions 54e to 54g. The protrusions 54i and the support portions 54e to 54g can support the lower end of the battery 2. The protrusions 54i are formed at intervals in the left-right direction. In this embodiment, the protrusions 54i are formed within the range where the drain opening 54d is formed. That is, the protrusions 54i extend linearly from the terminal port 53b to the drain opening 54d.

[0045] Fig. 7 is a vertical cross-sectional view of the lower part of the storage slot 3. Fig. 8 is a horizontal cross-sectional view of the storage device 1 according to the embodiment. A drain rail 81 is supported below the fixed panel 53. The drain rail 81 is a plate material bent into a U-shaped cross section. The drain rail 81 is installed so as to cover the drain outlet 53d from below. The drain rail 81 is fixed to the underside of the mounting panel 20. The drain rail 81 extends in the left-right direction. The drain rail 81 slopes downward as it moves to the right (to one side in the left-right direction). A drain hose 82 extending in the up-down direction is connected to the right end of the drain rail 81. The lower end of the drain hose 82 (see Figure 2) is led out to the outside of the housing 5. The drain rail 81 and the drain hose 82 constitute a drainage mechanism 80 of this embodiment.

[0046] When the storage device 1 is installed outdoors, it is exposed to rain. The storage slots 3 of the storage device 1 are provided with cover members (not shown), and empty storage slots 3 are closed with the cover members. This prevents rain from entering the empty storage slots 3. On the other hand, when a battery 2 is to be installed in the storage slot 3, the cover members are removed. Then, the battery 2 is inserted into the storage slot 3. At this time, the battery 2 hits the bottom member 54 and is received by the storage slot 3. Because the bottom member 54 is made of rubber, it is easy to absorb the impact of the battery 2 during insertion. The battery 2 is supported by the support portions 54e, 54f, 54g and the protrusion portion 54i of the bottom member 54. Since the battery 2 is also supported by the inner protrusion portion 54i surrounded by the support portions 54e to 54g, the battery 2 is easily supported over the entire wide surface of the bottom member 54.

[0047] A gap S0 (see FIG. 7) is formed between the inner surface of the slot case 51 and the battery 2. Therefore, if it rains during charging, rainwater will enter the slot case 51 through the insertion opening 45c of the battery guide 45, the opening 52a, and the gap S0. In this embodiment, the upper bottom surface 54a of the bottom member 54 of the storage slot 3 is inclined to have a height difference. Therefore, rainwater that has entered between the slot case 51 and the battery 2 flows along the upper bottom surface 54a of the bottom member 54 as indicated by arrows W in FIGS. 6 and 7 after reaching the upper bottom surface 54a. At this time, a bank portion 54h is formed around the terminal opening 54b, preventing the rainwater from flowing into the terminal opening 54b.

[0048] In addition, the upper bottom surface 54a is provided with a protrusion 54i extending toward the drain opening 54d. Therefore, water that reaches the upper bottom surface 54a is guided by the protrusion 53i and easily flows to the drain opening 54d. The water that flows into the drain opening 54d flows through the drain port 53d of the fixed panel 53, onto the drain rail 81, and is then drained to the outside of the housing 5 via the drain hose 82.

[0049] As described above, in this embodiment of the present invention, the storage device 1 is provided with a storage slot 3 in which a battery 2 is removably accommodated, and the bottom member 54 of the storage slot 3 has support portions 54e, 54f, 54g and a protrusion portion 54i that come into contact with the battery 2 when the battery 2 is accommodated, and a bottom surface 54a that has a height difference along a predetermined direction and does not come into contact with the battery 2. According to this configuration, the support portions 54e, 54f, 54g and the protrusion portion 54i support the stored battery 2 on the bottom member 54, while the bottom upper surface 54a, which has a height difference along a predetermined direction, ensures a gap between the bottom member 54 and the battery 2 through which water can move, making it easy to move water on the bottom member 54 in the predetermined direction. Therefore, it is possible to provide a storage device 1 that can easily prevent water from accumulating on the bottom member 54.

[0050] In this embodiment, the support portion includes a plurality of protrusions 54i extending in a predetermined direction.
