Japanese Patent Publication No. 2021-034312

If the power supply (battery) is not sufficiently charged, power is drawn from the power supply box built into the electronic device. However, if the power supply is firmly held in its holder, it may be difficult to remove it from the power supply box.

Therefore, a power supply box and/or electronic device that allows for easy power supply access is desirable.

A power supply box according to one embodiment includes a holder for holding a power supply and a pressing unit capable of pressing the power supply to remove it from the holder.

One embodiment of the electronic device includes the power supply box described above.

However, it should be noted that the drawings are schematic, and the proportions of dimensions, etc., may differ from those of reality.

[First Embodiment]
A power supply box according to the first embodiment will be described with reference to Figures 1 to 13. The power supply box may be sold independently or may be incorporated into an electronic device.

Figure 6 is a schematic cross-sectional view of the power supply box in the first state along the line 6A-6A in Figure 3. Figure 7 is a schematic cross-sectional view of the power supply box in the second state along the line 6A-6A in Figure 3. Figures 2 to 7 show the power supply box with the cover 20 (described later) closed. Figures 6 and 7 show the power supply box with a power supply installed.

The power supply box 100 may have a housing 10 and a cover 20. The housing 10 may have a shape capable of housing the power supply. The housing 10 may have sides 11 and a bottom 12.

The power source 200 may be, for example, a battery. The battery may be a primary battery or a secondary battery. The diagram illustrates the case where the power source 200 is a dry cell battery. In the diagram, the dry cell battery has shapes such as a D-cell, C-cell, AA-cell, AAA-cell, or AAA-cell. However, the dry cell battery is not limited to these shapes and may have various other shapes. For example, the dry cell battery may have a shape like a 9V rectangular dry cell battery or a coin-cell dry cell battery. Alternatively, the power source 200 may be a battery other than a dry cell battery.

The power box 100 may have an entrance/exit 14 for inserting the power supply 200 into the enclosure 10 and removing the power supply 200 from the enclosure 10. The cover 20 covers the entrance/exit 14. The cover 20 may be configured to transition between a state where the entrance/exit 14 is open and a state where it covers the entrance/exit 14.

In the illustrated embodiment, the cover 20 is connected to the housing 10 by a hinge 22. The cover 20 is configured to rotate around the pivot axis of the hinge 22. The rotation by the hinge 22 allows the cover 20 to transition between a state where the entrance 14 is open and a state where the entrance 14 is covered.

The opening mechanism for cover 20 is not limited to the illustrated configuration. For example, cover 20 may be configured to be detachable from housing 10.

The power box 100 may have a holder 30 for holding the power supply 200. The holder 30 may have electrical terminals 38 that are electrically connected to the power supply 200. While the power supply 200 is held in the holder 30, the power supply 200 is electrically connected to the electrical terminals 38.

The holder 30 may be configured to firmly and mechanically hold the power supply 200 so that the electrical connection of the power supply 200 does not unintentionally disconnect when using the power box 100 or electronic equipment. The mechanical configuration of the holder 30 is not particularly limited, and the holder 30 may have various mechanical configurations.

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 from the entrance/exit 14 of the housing 10. The bottom portion 34 may extend along one side of the power supply 200. The bottom portion 34 of the holder 30 may have a through-hole 36 through which the pressing unit 40, described later, passes.

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

The cover 20 preferably has a magnet 24. The magnet 24 is preferably a permanent magnet. Here, the term "permanent magnet" is used in the same sense as it is commonly used, and does not necessarily mean a component that permanently retains its magnetic properties. That is, unlike an electromagnet, a "permanent magnet" can be any component that retains its magnetic properties over a long period of time.

The magnet 24 may be positioned opposite the power supply 200 held in the holder 30. Preferably, the magnet 24 is positioned opposite the power supply 200 held in the holder 30 and spaced apart from the power supply 200. The magnet 24 may be provided, for example, inside the cover 20. Alternatively, the magnet 24 may be housed inside, for example, a component of the cover 20.

However, the magnet 24 is not essential. The power box 100 does not need to have a magnet 24.

The power box 100 may have a pressing unit 40. The pressing unit 40 is configured to press the power supply 200, which is held in the holder 30, in order to remove it from the holder 30. In a preferred example, the pressing unit 40 and the holder 30 are configured to be relatively movable between a first state (see Figure 6) where the pressing unit 40 is retracted from the area of the power supply 200 held in the holder 30, and a second state (see Figure 7) where the pressing unit 40 enters 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 the user operating the operation unit 60 described later.

In the second state, when the pressing unit 40 enters the area of the power supply 200 held by the holder 30 while the power supply 200 is still held by the holder 30, the power supply 200 is released from the holder 30, at least partially. This releases the strong mechanical hold of the power supply 200 by the holder 30. Therefore, a user attempting to remove the power supply 200 can easily retrieve it from the power supply box 100.

The configuration of the pressing unit 40 is not particularly limited. A preferred configuration of the pressing unit 40 is described below as an example. The pressing unit 40 may be located on the side opposite to the cover 20 with respect to the power supply 200 held in the holder 30. Specifically, the pressing unit 40 may be attached to a base 50 spaced apart from the bottom 12 of the housing 10. The pressing unit 40 may be composed of pins 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 configuration, the pressing unit 40 is attached to the base 50. Alternatively, the pressing unit 40 may be molded integrally with the base 50.

It is preferable that the pressing unit 40 and the holder 30 are configured to be able to move relative to each other in the direction toward the entrance/exit 14 from the opposite side. In the illustrated embodiment, the gap between the bottom 12 of the housing 10 and the bottom 34 of the holder 30 and the base 50 is operated to widen and narrow. This allows the pressing unit 40 and the holder 30 to move relative to each other in the direction toward the entrance/exit 14 from the opposite side. Accordingly, in the second state described above, the pressing unit 40 is configured to enter the area of the power supply 200 held by the holder 30 through the through-hole 36 in the bottom 34 of the holder 30.

When the pressing unit 40 moves relative to the entrance/exit 14 from the opposite side toward the entrance/exit 14, the power supply 200 is pushed upward toward the entrance/exit 14. Therefore, the user can more easily remove the power supply 200 that has been detached from the holder 30.

Furthermore, if the cover 20 is equipped with a magnet 24, when the pressing unit 40 pushes up the power supply 200 while the cover 20 is closed, the power supply 20, which has detached from the holder 30, is attracted to the magnet 24 and attaches to the cover 20. After this, when the cover 20 is opened, the power supply 200 is already attached to the cover 20, making it easier for the user to retrieve the power supply 200.

The power box 100 preferably has an elastic member 70 that biases the pressing unit 40 and the holder 30 toward the first state described above. This ensures that the pressing unit 40 is retracted from the power supply 200 under normal conditions. In this case, the pressing unit 40 transitions from the first state (see Figure 6) to the second state (see Figure 7) by the user operating the operation unit 60, which will be described later.

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. When no external force is applied, the elastic member 70 widens the gap between the bottom 12 and the base 50 of the housing 10, thereby retracting the pressing unit 40 from the area of the power supply 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, causing the pressing unit 40 to enter the area of the power supply 200 through the through-hole 36.

The power box 100 may have an operating section 60 for relative movement of the pressing unit 40 and the holder 30. In the first embodiment, with the base 50 fixed, the user presses the housing 10 and/or cover 20 toward the base 50 (towards arrow F1 in Figure 7), causing the pressing unit 40 to enter the area of the power supply 200. In this case, the housing 10 and/or cover 20 constitute the operating section 60. Therefore, it can be said that the operating section 60 is provided on the housing 10 and/or cover 20. In this case, the base 50 may be integrally configured with the components constituting the electronic equipment.

Alternatively, with the housing 10 and/or cover 20 fixed in place, the user presses the base 50 toward the housing 10 and/or cover 20 (towards arrow F2 in Figure 7), causing the pressing unit 40 to enter the area of the power supply 200. In this case, the base 50 constitutes the operating unit 60. In this case, the housing 10 may be integrally constructed with the components that make up the electronic device.

The pressing unit 40 is preferably configured to press a position on the power supply 200 that is offset in the longitudinal direction from the longitudinal center of the power supply 200 held in the holder 30. In the illustrated embodiment, the pressing unit 40 is configured to press a position offset towards the positive pole from the longitudinal center of the power supply 200. This allows the pressing unit 40 to release the power supply 200 from the holder 30 with relatively little force. The pressing position of the power supply 200 by the pressing unit 40 may be, for example, outside of 2/5 of the distance between the two longitudinal edges of the power supply 200.

The power supply box 100 preferably includes a switching unit 80. The switching unit 80 is configured to switch between a state that allows relative movement between the pressing unit 40 and the holder 30 (unlocked state) and a state that prohibits relative movement between the pressing unit 40 and the holder 30 (locked state).

The following describes an example of the configuration of the switching unit 80 with reference to Figures 8 to 13. Figure 8 is a schematic cross-sectional view of the power supply box in the unlocked state along the 5A-5A line in Figure 2. Figure 9 is a schematic cross-sectional view of the power supply box in the unlocked state and first state along the 9A-9A line in Figure 8. Figure 10 is a schematic cross-sectional view of the power supply box in the unlocked state and second state along the 9A-9A line in Figure 8. Figure 11 is a schematic cross-sectional view of the power supply box in the locked state along the 5A-5A line in Figure 2. Figure 12 is a schematic cross-sectional view of the power supply box in the locked state along the 12A-12A line in Figure 11.

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 interior of the housing 10, for example, to a position facing the side 11 of the housing 10.

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 slide along its longitudinal direction (the direction of arrow A in Figures 8 and 11).

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

The shaft 81 has a small-diameter portion 82 and a large-diameter portion 83. The small-diameter portion 82 is the part with a smaller diameter than 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 integrally formed as a single hole.

The large-diameter portion 87 is sized to accommodate the large-diameter portion 83 of the shaft 81. The elongated hole portion 88 extends along the direction of relative movement between the shaft 81 and the receiving member 85. The width W of the elongated hole portion 88 in the direction perpendicular to the direction of relative movement is smaller than the diameter of the large-diameter portion 83 of the shaft 81 and larger than the diameter of the small-diameter portion 82 of the shaft 81. In other words, the elongated hole portion 88 can accommodate the small-diameter portion 82 of the shaft 81, but cannot accommodate the large-diameter portion 83 of the shaft 81.

By sliding the shaft 81 in its longitudinal direction, the smaller 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 to 10, the shaft 81 is movable (relatively movable) in a direction that pushes it downwards toward the base 50 together with the housing 10 and holder 30. Therefore, the power supply 200 can be extracted by the pressing unit 40 (unlocked state).

Furthermore, the sliding of the shaft 81 in its longitudinal direction allows the large-diameter portion 83 of the shaft 81 to be aligned with the hole 86 formed in the receiving member 85. In this case, as shown in Figures 11 and 12, the large-diameter portion 83 of the shaft 81 cannot enter the elongated hole 88, thus preventing relative movement between the pressing unit 40 and the holder 30 (locked state). The user only needs to keep the power box 100 locked except when removing the power supply 200. This reduces the risk of the power supply 200 being unintentionally disconnected.

Although an example 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 on the outside of the housing 10. The configuration of the switching unit 80 only needs to be switchable between an unlocked state and a locked state. Also, if it is not necessary, the switching unit 80 may not be provided.

[Second Embodiment]
The power supply box 100 according to the second embodiment will be described with reference to Figures 13 and 14. Figure 13 is a schematic cross-sectional view of the power supply box according to the second embodiment in a first state. Figure 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 the same as in the first embodiment, where the pressing unit 40 is retracted from the area of the power supply 200 held by the holder 30. The second state is the same as in the first embodiment, where the pressing unit 40 has entered the area of the power supply 200 held by the holder 30.

Figure 13 shows the cover 20 in the closed position. Figure 14 shows the cover 20 in the removed position.

In the second embodiment, components similar to those in the first embodiment are denoted by the same reference numerals as in the first embodiment. Furthermore, descriptions of components similar to those in the first embodiment may be omitted.

In the second embodiment, the configuration of the power supply 200 and the holder 30 is the same as in the first embodiment. In the second embodiment, the base 50 is not provided. The pressing unit 40 is provided at 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 in the first embodiment.

In the second embodiment, the power box 100 also has an elastic member 70 that biases the pressing unit 40 and the holder 30 toward the first state described above. 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.

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

In the second embodiment, the operating unit 60 is located in a position accessible through the entrance/exit 14. Specifically, the operating unit 60 is located in a position accessible to the user through the entrance/exit 14 when the cover 20 is open.

The operating section 60 may be composed of a wall portion 37 integrally and inseparably attached to the holder 30. The wall portion 37 may have a surface facing the entrance/exit 14. The user can push down the holder 30 toward the bottom 12 of the housing 10 by pressing down on the wall portion 37. This causes the pressing unit 40 to enter the area of the power supply 200 through the through-hole 36 of the holder 30, thereby detaching the power supply 200 from the holder 30.

In the second embodiment, the user cannot access the operating 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.

In the second embodiment, if the power box 100 is mounted on an electronic device, the housing 10 may be integrally configured with the elements constituting the electronic device, such as the housing of the electronic device.

[Third Embodiment]
The power supply box 100 according to the third embodiment will be described with reference to Figures 15 and 16. Figure 15 is a schematic cross-sectional view of the power supply box according to the third embodiment in a first state. Figure 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 is retracted from the area of the power supply 200 held by the holder 30, similar to the first embodiment. The second state is a state in which the pressing unit 40 has entered the area of the power supply 200 held by the holder 30, similar to the first embodiment.

Figure 15 shows the cover 20 in the closed position. Figure 16 shows the cover 20 in the removed position.

In the third embodiment, components similar to those in the first embodiment are denoted by the same reference numerals as in the first embodiment. Furthermore, descriptions of components similar to those in the first embodiment may be omitted.

In the third embodiment, the configuration of the power supply 200 and the holder 30 is the same as 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 in the first embodiment.

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

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

In the third embodiment, the power box 100 also has an elastic member 70 that biases the pressing unit 40 and the holder 30 toward the first state described above. The elastic member 70 may be provided, for example, between the operating unit 60 and the bottom 12 of the housing 10. In the third embodiment, when the user presses the operating unit 60, the pressing unit 40 enters the area of the power supply 200 through the through hole 36 of the holder 30, and the power supply 200 is released from the holder 30.

In the third embodiment, the user cannot access the operating 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.

In the third embodiment, if the power box 100 is mounted on an electronic device, the housing 10 may be integrally configured with the elements constituting the electronic device, such as the housing of the electronic device.

In the third embodiment, when the user operates the operating unit 60, the operating unit 60 is pushed down from the entrance/exit 14 of the power box 100 toward the bottom 12 of the housing 10. Alternatively, the operating unit 60 may be provided, for example, on the side of the housing 10, i.e., on a wall rising from the bottom 12. In this case, the connecting movable part 44 that mechanically connects the operating unit 60 and the pressing unit 40 only needs to have a mechanism that converts horizontal movement into vertical movement (the direction from the entrance/exit 14 toward the bottom 12 of the housing 10). Here, the horizontal direction corresponds to the direction along the plane that intersects the direction from the entrance/exit 14 toward the bottom 12 of the housing 10.

In the first to third embodiments, the power box 100 is configured to house one power supply 200. Alternatively, the power box 100 may be configured to house multiple power supplies 200. In this case, multiple pressing units 40 may be provided, aligned with the positions of the multiple power supplies 200. Preferably, the multiple pressing units 40 are configured to move relative to each other in conjunction with a single operation by the operating unit 60. This allows multiple power supplies 200 to be removed simultaneously. Such multiple pressing units 40 can be realized by multiple pins provided to align with the positions of the multiple power supplies 200.
