[0009] Hereinafter, embodiments will be described with reference to the drawings. In the following drawings, the same or similar parts are denoted by the same or similar reference numerals. However, it should be noted that the drawings are schematic and the ratios of the dimensions may differ from those of the actual parts.

[0010] [First embodiment] A power supply box according to a first embodiment will be described with reference to Figures 1 to 13. The power supply box may be distributed independently, or may be provided in an electronic device.

[0011] FIG. 1 is a schematic perspective view of a power supply box according to a first embodiment. FIG. 1 shows the power supply box in a state where a cover 20, which will be described later, is open. FIG. 2 is a schematic side view of the power supply box according to the first embodiment. FIG. 3 is a schematic top view of the power supply box as seen from the direction of arrow 3A in FIG. 2. FIG. 4 is a schematic side view of the power supply box as seen from the direction of arrow 4A in FIG. 2. FIG. 5 is a schematic cross-sectional view of the power supply box taken along line 5A-5A in FIG. 2. FIG. 5 shows a state where a power supply is not housed. FIG. 6 is a schematic cross-sectional view of the power supply box in a first state taken along line 6A-6A in FIG. 3. FIG. 7 is a schematic cross-sectional view of the power supply box in a second state taken along line 6A-6A in FIG. 3. FIGS. 2 to 7 show the power supply box in a state where a cover 20, which will be described later, is closed. FIGS. 6 and 7 show a state where a power supply is housed.

[0012] The power supply box 100 may include a housing 10 and a cover 20. The housing 10 may have a shape capable of accommodating the power supply. The housing 10 may have a side 11 and a bottom 12.

[0013] The power supply 200 may be, for example, a battery. The battery may be a primary battery or a secondary battery. In the figures, the power supply 200 is illustrated as a dry battery. In the figures, the dry battery has a shape similar to a D battery, a C battery, a AA battery, an AAA battery, or a D battery. However, the dry battery is not limited to these shapes and may have various shapes. For example, the dry battery may have a shape similar to a 9V square battery or a coin battery. Alternatively, the power supply 200 may be a battery other than a dry battery.

[0014] The power supply box 100 may have an entrance 14 for inserting the power supply 200 into the housing 10 or removing the power supply 200 from the housing 10. The cover 20 covers the entrance 14. The cover 20 may be configured to be able to transition between a state in which the entrance 14 is open and a state in which the entrance 14 is covered.

[0015] In the illustrated embodiment, the cover 20 is connected to the housing 10 by a hinge 22. The cover 20 is configured to be rotatable around the rotation axis of the hinge 22. By rotating by the hinge 22, the cover 20 is configured to be able to transition between a state in which the entrance 14 is open and a state in which the entrance 14 is covered.

[0016] The opening mechanism of the cover 20 is not limited to the illustrated embodiment. For example, the cover 20 may be configured to be detachable from the housing 10.

[0017] The power supply box 100 may have a holder 30 that holds the power supply 200. The holder 30 may have electrical terminals 38 that are electrically connected to the power supply 200. When the power supply 200 is held in the holder 30, the power supply 200 is electrically connected to the electrical terminals 38.

[0018] Holder 30 may be configured to firmly mechanically hold power supply 200 so as to prevent unintentional disconnection of power supply 200 when power supply box 100 or an electronic device is in use. The mechanical configuration of holder 30 is not particularly limited, and holder 30 may have various mechanical configurations.

[0019] In the illustrated example, the holder 30 may have a pair of side portions 32 and a bottom portion 34. The bottom portion 34 may be located on the opposite side of the housing 10 from the entrance 14. The bottom portion 34 may extend along one side of the power source 200. The bottom portion 34 of the holder 30 may have a through-hole 36 through which a pressing unit 40, which will be described later, passes.

[0020] The pair of side portions 32 of the holder 30 are configured to face the end faces of the power source 200. When the power source 200 is a dry battery, the pair of side portions 32 of the holder 30 face the positive and negative terminals of the dry battery. In this case, the pair of side portions 32 of the holder 30 each have an electrical terminal 38. The power source 200 is mechanically and firmly held by being sandwiched between the pair of side portions 32 of the holder 30.

[0021] The cover 20 preferably has a magnet 24. The magnet 24 is preferably a permanent magnet. Here, the term "permanent magnet" has the same meaning as it is normally used, and does not necessarily mean a material that permanently retains its magnetic properties. In other words, a "permanent magnet" differs from an electromagnet in that it is sufficient for the material to retain its magnetic properties for a long period of time.

[0022] The magnet 24 may be provided at a position facing the power source 200 held in the holder 30. Preferably, the magnet 24 faces the power source 200 held in the holder 30 and is spaced apart from the power source 200. The magnet 24 may be provided, for example, on the inside of the cover 20. Alternatively, the magnet 24 may be provided, for example, housed inside a member that constitutes the cover 20.

[0023] However, the magnet 24 is not essential. The power supply box 100 does not necessarily have to include the magnet 24.

[0024] The power supply box 100 may include a pressing unit 40. The pressing unit 40 is configured to be able to press the power supply 200 held in the holder 30 so as to remove the power supply 200 from the holder 30. In a preferred example, the pressing unit 40 and the holder 30 are configured to be able to move relative to each other between a first state (see FIG. 6 ) in which the pressing unit 40 is retracted from the area of ​​the power supply 200 held in the holder 30, and a second state (see FIG. 7 ) in which the pressing unit 40 has entered the area of ​​the power supply 200 held in the holder 30. Such relative movement of the pressing unit 40 and the holder 30 can be achieved, for example, by a user operating an operation unit 60, which will be described later.

[0025] When the power supply 200 is held in the holder 30, the pressing unit 40 enters the second state into the area of ​​the power supply 200 held in the holder 30, causing the power supply 200 to at least partially detach from the holder 30. This releases the strong mechanical hold of the power supply 200 by the holder 30. Therefore, a user who wishes to remove the power supply 200 can easily retrieve the power supply 200 from the power supply box 100.

[0026] The configuration of the pressing unit 40 is not particularly limited. A preferred embodiment of the configuration of the pressing unit 40 will be described below as an example. The pressing unit 40 may be provided on the opposite side of the cover 20 with respect to the power source 200 held in the holder 30. Specifically, the pressing unit 40 may be attached to a base 50 that is spaced apart from the bottom 12 of the housing 10. The pressing unit 40 may be configured by a pin extending from the base 50 toward the bottom 12 of the housing 10 or the bottom 34 of the holder 30. An elastic member (not shown) may be provided at the tip of the pin. In the illustrated embodiment, the pressing unit 40 is attached to the base 50. Alternatively, the pressing unit 40 may be molded integrally with the base 50.

[0027] It is preferable that the pressing unit 40 and the holder 30 are configured to be relatively movable in a direction from the opposite side of the entrance 14 toward the entrance 14. In the illustrated embodiment, the gap between the bottom 12 of the housing 10 or the bottom 34 of the holder 30 and the base 50 is operated to widen or narrow. As a result, the pressing unit 40 and the holder 30 are configured to be relatively movable in a direction from the opposite side of the entrance 14 toward the entrance 14. Accordingly, the pressing unit 40 is configured to enter the area of ​​the power source 200 held by the holder 30 through the through-hole 36 in the bottom 34 of the holder 30 in the second state.

[0028] When the pressing unit 40 moves relatively from the opposite side of the entrance 14 toward the entrance 14, the power supply 200 is pushed up toward the entrance 14. This makes it easier for the user to remove the power supply 200 that has come out of the holder 30.

[0029] Furthermore, if the cover 20 is equipped with the magnet 24, when the pressing unit 40 pushes up the power supply 200 while the cover 20 is closed, the power supply 20 that has come off the holder 30 is attracted to the magnet 24 and attached to the cover 20. When the cover 20 is then opened, the power supply 200 is already attached to the cover 20, allowing the user to retrieve the power supply 200 more easily.

[0030] The power supply box 100 preferably has an elastic member 70 that biases the pressing unit 40 and the holder 30 toward the first state. This allows the pressing unit 40 to retract from the power supply 200 in the normal state. In this case, when the user operates the operation section 60 (described later), the pressing unit 40 transitions from the first state (see FIG. 6) to the second state (see FIG. 7).

[0031] In the illustrated embodiment, the elastic member 70 is provided between the bottom 12 and the base 50 of the housing 10. The elastic member 70 may be made of, for example, rubber or a spring. The elastic member 70 widens the gap between the bottom 12 and the base 50 of the housing 10 when no external force is applied, thereby allowing the pressing unit 40 to retreat from the area of ​​the power source 200. When the elastic member 70 is subjected to an external force that compresses it, the gap between the bottom 12 and the base 50 of the housing 10 narrows, allowing the pressing unit 40 to enter the area of ​​the power source 200 through the through-hole 36.

[0032] The power supply box 100 may have an operating part 60 for moving the pressing unit 40 and the holder 30 relative to each other. In the first embodiment, with the base 50 fixed, the user presses the housing 10 and / or the cover 20 toward the base 50 (toward the arrow F1 in FIG. 7), causing the pressing unit 40 to enter the area of ​​the power supply 200. In this case, the housing 10 and / or the cover 20 constitute the operating part 60. Therefore, it can be said that the operating part 60 is provided on the housing 10 and / or the cover 20. In this case, the base 50 may be configured integrally with a member that constitutes the electronic device.

[0033] Instead, with the housing 10 and / or cover 20 fixed, the user presses the base 50 toward the housing 10 and / or cover 20 (toward the arrow F2 in FIG. 7), causing the pressing unit 40 to enter the area of ​​the power source 200. In this case, the base 50 constitutes the operation unit 60. In this case, the housing 10 may be formed integrally with the components that constitute the electronic device.

[0034] The pressing unit 40 is preferably configured to be able to press a position on the power source 200 that is shifted in the longitudinal direction from the center of the power source 200 held in the holder 30. In the illustrated embodiment, the pressing unit 40 is configured to press a position on the power source 200 that is shifted toward the positive pole from the center of the power source 200 in the longitudinal direction. This allows the pressing unit 40 to remove the power source 200 from the holder 30 with a relatively small force. The position on the power source 200 pressed by the pressing unit 40 may be, for example, a position that is more than 2 / 5 of the distance between both edges of the power source 200 in the longitudinal direction.

[0035] The power supply box 100 preferably includes a switching unit 80. The switching unit 80 is configured to switch between a state in which the pressing unit 40 and the holder 30 are allowed to move relative to each other (unlocked state) and a state in which the pressing unit 40 and the holder 30 are prohibited from moving relative to each other (locked state).

[0036] An example of the configuration of the switching unit 80 will be described below with reference to FIGS. 8 to 13. FIG. 8 is a schematic cross-sectional view of the power supply box in the unlocked state taken along line 5A-5A in FIG. 2. FIG. 9 is a schematic cross-sectional view of the power supply box in the unlocked state and in a first state taken along line 9A-9A in FIG. 8. FIG. 10 is a schematic cross-sectional view of the power supply box in the unlocked state and in a second state taken along line 9A-9A in FIG. 8. FIG. 11 is a schematic cross-sectional view of the power supply box in the locked state taken along line 5A-5A in FIG. 2. FIG. 12 is a schematic cross-sectional view of the power supply box in the locked state taken along line 12A-12A in FIG. 11.

[0037] The switching unit 80 has a shaft 81 extending in one direction and a receiving member 85 having a hole 86 through which the shaft 81 passes. The receiving member 85 is fixed to the base 50. The receiving member 85 may extend from the base 50 to the inside of the housing 10, for example, to a position facing the side portion 11 of the housing 10.

[0038] Both ends of the shaft 81 may be passed through holes 11a provided in the side portion 11 of the housing 10. In this way, the shaft 81 is attached to the housing 10. However, the shaft 81 may be configured to be slidable along the longitudinal direction of the shaft 81 (the direction of arrow A in FIGS. 8 and 11).

[0039] The shaft 81 is attached to the housing 10, and the receiving member 85 is fixed to the base 50. As a result, as the pressing unit 40 and the holder 30 move relative to each other, the shaft 81 and the receiving member 85 also move relative to each other.

[0040] The shaft 81 has a small diameter portion 82 and a large diameter portion 83. The small diameter portion 82 has a diameter smaller than that of the large diameter portion 83. The shaft 81 passes through a hole 86 formed in the receiving member 85. The hole 86 formed in the receiving member 85 includes a large diameter portion 87 and an elongated hole portion 88 extending from the large diameter portion 87. The large diameter portion 87 and the elongated hole portion 88 are a single hole formed integrally.

[0041] Large diameter portion 87 has a size that allows it to receive large diameter portion 83 of shaft 81. Slot portion 88 extends in the direction of relative movement between shaft 81 and receiving member 85. The width W of slot portion 88 in a direction perpendicular to the direction of relative movement is smaller than the diameter of large diameter portion 83 of shaft 81 and larger than the diameter of small diameter portion 82 of shaft 81. In other words, slot portion 88 can receive small diameter portion 82 of shaft 81 but cannot receive large diameter portion 83 of shaft 81.

[0042] By sliding the shaft 81 in the longitudinal direction of the shaft 81, the small diameter portion 82 of the shaft 81 can be aligned with the hole 86 formed in the receiving member 85. In this case, as shown in Figures 9 and 10, the shaft 81 can move (relatively move) together with the housing 10 and the holder 30 in a direction in which it is pressed down toward the base 50. This allows the power source 200 to be removed by the pressing unit 40 (unlocked state).

[0043] Furthermore, by sliding the shaft 81 in the longitudinal direction of the shaft 81, the large diameter portion 83 of the shaft 81 can be aligned with the hole 86 formed in the receiving member 85. In this case, as shown in FIGS. 11 and 12, the large diameter portion 83 of the shaft 81 cannot enter the elongated hole 88, and therefore the pressing unit 40 and the holder 30 cannot move relative to each other (locked state). The user only needs to keep the power supply box 100 in the locked state except when removing the power supply 200. This reduces the risk of the power supply 200 being unintentionally removed.

[0044] Although an example of the configuration of the switching unit 80 has been described in detail, the configuration of the switching unit 80 is not limited to the above. For example, the switching unit 80 may be provided outside the housing 10. The configuration of the switching unit 80 only needs to be capable of switching between an unlocked state and a locked state. Furthermore, if not necessary, the switching unit 80 may not be provided.

[0045] [Second embodiment] The power supply box 100 according to the second embodiment will be described with reference to FIGS. 13 and 14. FIG. 13 is a schematic cross-sectional view of the power supply box according to the second embodiment in a first state. FIG. 14 is a schematic cross-sectional view of the power supply box according to the second embodiment in a second state. Here, the first state is a state in which the pressing unit 40 has retreated from the area of ​​the power supply 200 held in the holder 30, as in the first embodiment. Furthermore, the second state is a state in which the pressing unit 40 has entered the area of ​​the power supply 200 held in the holder 30, as in the first embodiment.

[0046] 13 shows a state in which the cover 20 is closed, and FIG. 14 shows a state in which the cover 20 is removed.

[0047] In the second embodiment, the same components as those in the first embodiment are denoted by the same reference numerals as those in the first embodiment, and the description of the same components as those in the first embodiment may be omitted.

[0048] In the second embodiment, the configurations of the power supply 200 and the holder 30 are the same as those in the first embodiment. In the second embodiment, the base 50 is not provided. The pressing unit 40 is provided on the bottom 12 of the housing 10 of the power supply box 100. The shape and position of the pressing unit 40 may be the same as those in the first embodiment.

[0049] In the second embodiment, the power supply box 100 also has an elastic member 70 that biases the pressing unit 40 and the holder 30 toward the first state. The elastic member 70 is provided between the bottom 12 of the housing 10 and the bottom 34 of the holder 30. In the second embodiment, the distance between the bottom 12 of the housing 10 and the bottom 34 of the holder 30 is configured to be variable. The configuration of the elastic member 70 is the same as in the first embodiment.

[0050] In the second embodiment, as in the first embodiment, the power source 200 can be easily removed from the holder 30 by the pressing unit 40.

[0051] In the second embodiment, the operation unit 60 is provided at a position accessible through the entrance 14. Specifically, the operation unit 60 is provided at a position accessible by a user through the entrance 14 when the cover 20 is open.

[0052] The operating section 60 may be configured by a wall section 37 that is configured as an integral part of the holder 30. The wall section 37 may have a surface facing the entrance 14. A user can press the wall section 37 to push the holder 30 down toward the bottom section 12 of the housing 10. This causes the pressing unit 40 to enter the area of ​​the power source 200 through the through-hole 36 of the holder 30 and remove the power source 200 from the holder 30.

[0053] In the second embodiment, the user cannot access the operation unit 60 when the cover 20 is closed. Therefore, even if the switching unit 80 is not provided, the user will not accidentally remove the power supply 200 when the cover 20 is closed.

[0054] In the second embodiment, when the power supply box 100 is mounted on an electronic device, the housing 10 may be configured integrally with an element that constitutes the electronic device, for example, the housing of the electronic device.

[0055] [Third embodiment] The power supply box 100 according to the third embodiment will be described with reference to FIGS. 15 and 16. FIG. 15 is a schematic cross-sectional view of the power supply box according to the third embodiment in a first state. FIG. 16 is a schematic cross-sectional view of the power supply box according to the third embodiment in a second state. Here, the first state is a state in which the pressing unit 40 has retreated from the area of ​​the power supply 200 held in the holder 30, as in the first embodiment. Furthermore, the second state is a state in which the pressing unit 40 has entered the area of ​​the power supply 200 held in the holder 30, as in the first embodiment.

[0056] 15 shows a state in which the cover 20 is closed, and FIG. 16 shows a state in which the cover 20 is removed.

[0057] In the third embodiment, the same components as those in the first embodiment are denoted by the same reference numerals as those in the first embodiment, and the description of the same components as those in the first embodiment may be omitted.

[0058] In the third embodiment, the configurations of the power supply 200 and the holder 30 are the same as those in the first embodiment. In the third embodiment, the base 50 is not provided. The pressing unit 40 is provided in the space below the power supply box 100. The shape and position of the pressing unit 40 may be the same as those in the first embodiment.

[0059] The pressing unit 40 may be connected to the operating unit 60 via a mechanically movable connecting part 44. In the third embodiment, the operating unit 60 is located to the side of the holder 30, and is provided at a position accessible through the entrance 14. Specifically, the operating unit 60 is provided at a position accessible by a user through the entrance 14 when the cover 20 is open.

[0060] The operating unit 60 may be configured to be pressable by a user. The movable connecting unit 44 has a structure that converts downward movement of the operating unit 60 into upward movement of the pressing unit 40. For example, the movable connecting unit 44 may have a rod-like or plate-like shape that is rotatable around a rotation axis 44a. The pressing unit 40 is connected to one end of the movable connecting unit 44. The operating unit 60 is connected to the other end of the movable connecting unit 44. As a result, when the operating unit 60 moves in one direction, the pressing unit 40 moves in the direction opposite to the movement direction of the operating unit 60.

[0061] In the third embodiment, the power supply box 100 also has an elastic member 70 that biases the pressing unit 40 and the holder 30 toward the first state. The elastic member 70 may be provided, for example, between the operation unit 60 and the bottom 12 of the housing 10. In the third embodiment, when a user presses the operation unit 60, the pressing unit 40 enters the area of ​​the power supply 200 through the through-hole 36 of the holder 30 and removes the power supply 200 from the holder 30.

[0062] In the third embodiment, the user cannot access the operation unit 60 when the cover 20 is closed. Therefore, even if the switching unit 80 is not provided, the user will not accidentally remove the power supply 200 when the cover 20 is closed.

[0063] In the third embodiment, when the power supply box 100 is mounted on an electronic device, the housing 10 may be configured integrally with an element that constitutes the electronic device, for example, the housing of the electronic device.

[0064] In the third embodiment, when a user operates the operation unit 60, the operation unit 60 is pressed from the entrance 14 of the power supply box 100 toward the bottom 12 of the housing 10. Alternatively, the operation unit 60 may be provided, for example, on a side surface of the housing 10, i.e., on a wall portion erected from the bottom 12. In this case, the connecting movable part 44 that mechanically connects the operation unit 60 and the pressing unit 40 to each other may have a mechanism that converts horizontal movement into vertical movement (the direction from the entrance 14 toward the bottom 12 of the housing 10). Here, the horizontal direction corresponds to the direction along a plane that intersects with the direction from the entrance 14 toward the bottom 12 of the housing 10.

[0065] In the first to third embodiments, the power supply box 100 is configured to house one power supply 200. Alternatively, the power supply box 100 may be configured to house multiple power supplies 200. In this case, multiple pressing units 40 may be provided to match the positions of the multiple power supplies 200. It is preferable that the multiple pressing units 40 are configured to be able to move relative to one another in conjunction with one another in response to a single operation by the operating section 60. This makes it possible to remove multiple power supplies 200 all at once. Such multiple pressing units 40 can be realized by multiple pins provided to match the positions of the multiple power supplies 200.

[0066] It should be noted that the above description defines at least the inventions described in the appended notes below.
