It has a rectangular parallelepiped shape with chamfered corners and functions as a casing for housing the rechargeable battery 20 . Hereinafter, the back surface of the design surface 14 that is mainly viewed by the user is referred to as the back surface 16, the left side surface when the user visually recognizes the design surface 14 is referred to as the left side surface 34, and the right side surface is referred to as the right side surface 36. do. Also, the depth is the direction from the design surface 14 to the back 16 (or vice versa), the width is the direction from the left side 34 to the right side 36 (or vice versa), and the bottom 30 to the top cover 32 (or vice versa). The direction toward is expressed as height.

Two grounding projections 40a and 40b are formed on the bottom surface 30 of the charging and feeding unit 12 so as to protrude toward the ground. Further, as shown in FIG. 2, mounting recesses 42a and 42b are formed by partially cutting out the bottom surface 30, the rear surface 16, the left side surface 34 and the right side surface 36. are provided with wheels 44a, 44b whose thickness is smaller than the width of the mounting recesses 42a, 42b. The charging and power supply unit 12 is a so-called self-supporting casing that can maintain an upright posture by contacting parts of the wheels 44a and 44b and the grounding projections 40a and 40b with the ground.

The rear surface 16 is further provided with two potches 46a and 46b projecting rearward. When the charging and power supply unit 12 is in an upright posture, for example, a cord or cable can be wound around these potch portions 46a and 46b. Also, when the charging and power supply unit 12 is in a lying posture with the back surface 16 facing the ground, the potted portions 46a and 46b serve as legs that come into contact with the ground.

A grip concave portion 48 extending in the width direction and recessed toward the design surface 14 is formed between the potch portions 46a and 46b. The inner upper surface of the grip recess 48 is recessed toward the top cover 32 from the upper opening of the grip recess 48 . In other words, a slight clearance toward the top cover 32 is formed above the grip recess 48 . By inserting a finger into this clearance, the user can lift charging and power supply unit 12 in the standing posture.

As shown in FIG. 1, the design surface 14 is provided with a USB terminal 50 (power supply terminal) to which a USB cable can be connected and an outlet 52 (power supply terminal) to which a commercial power plug can be connected.

A substantially U-shaped handle 58 is accommodated in the stepped portion 56 . The tip of the handle 58 is connected to the vicinity of the back surface 16 via a first pivot shaft (not shown), so that the handle 58 can rotate. Hereinafter, the state in which the handle 58 is stored in the stepped portion 56 as shown in FIG. 1 is called the folded state, and the state in which the handle 58 is raised as shown in FIG. 3 is called the grippable state.

As shown in FIG. 4, a plurality of entering protrusions 60 and entering recesses 62 are formed on the left side surface 34 . A permanent magnet is embedded in the entry convex portion 60 , while a magnetized disc made of a ferromagnetic material (for example, iron) is held in the bottom portion of the entry recess portion 62 . A plurality of stepped screw holes 64 are formed in the left side surface 34 , and mounting screws 66 are screwed into the screw portions of the stepped screw holes 64 . Further, a power supply insertion port 68 as an input terminal is formed in the vicinity of the back surface 16 and the wheels 44a and 44b.

Similarly, on the right side surface 36, as shown in FIG. 5, an entry convex portion 60 in which a permanent magnet is embedded and an entry concave portion 62 holding a magnetized disk made of a ferromagnetic material such as iron at the bottom are respectively provided. A plurality of them are formed. A plurality of stepped screw holes 64 are also formed in the right side surface 36, and mounting screws 66 are screwed into the threaded portions thereof. Further, an entry plug 70 as a supply terminal is provided near the back surface 16 and the wheels 44a, 44b. The entrance plug 70 is rotatably held, and is entirely housed in the housing hole by rotation.

Left side 34 and right side 36 are typically fitted with left cover panel 72a and right cover panel 74a, respectively. The inner surface facing the left side surface 34 of the left cover panel 72a and the inner surface facing the right side surface 36 of the right cover panel 74a are provided with receiving recesses 76a into which the entering projections 60 enter, and magnetically attracted recesses 62 entering into the entering recesses 62. Protrusions 78a are provided respectively. A magnetized disc made of a ferromagnetic material (for example, iron) is held at the bottom of the receiving recess 76a, while a permanent magnet is embedded in the magnetized protrusion 78a. Therefore, in the left cover panel 72a and the right cover panel 74a, the permanent magnet of the entering convex portion 60 is magnetically attached to the magnetically attached disk of the receiving concave portion 76a, and the permanent magnet of the magnetically attached convex portion 78a is magnetically attached to the concave portion 62 to be entered. By being magnetically attached to the board, it is detachably held on each of the left side surface 34 and the right side surface 36 . Neither the permanent magnets nor the magnetized disks are shown.

As shown in FIG. 6, the right side surface 36 is provided with a female connector 80 into which the male connector of the AC adapter cord is inserted. This AC adapter cord electrically connects the charging plug in the storage chamber 18 and the outlet 52, thereby enabling the rechargeable battery 20 to be charged. The AC adapter cord may be wound around the potch portions 46a and 46b.

As shown in FIGS. 1 and 6, the top cover 32 is rotatable via a second rotating shaft (not shown) provided in the vicinity of the rear surface 16. As shown in FIG. As the top cover 32 rotates, the storage chamber 18 is opened or closed. When the top cover 32 is rotated to open the storage chamber 18 , the rechargeable battery 20 can be taken out of the storage chamber 18 .

In the above configuration, a charging plug (none of which is shown) that enters into the plug insertion port is provided in the housing chamber 18 . The rechargeable battery 20 is charged by inputting external power from the AC adapter cord and charging plug to the terminals in the plug receptacle.

As understood from FIG. 6, the storage chamber 18 extends so as to be inclined with respect to the height direction. That is, when the charging and power supply unit 12 is in the upright posture, the rechargeable battery 20 is in the tilted posture. Since the accommodation chamber 18 is inclined in this manner, the bottom surface of the accommodation chamber is inclined with respect to the vertical direction. Further, a discharge path 82 is formed from the deepest corner of the bottom surface of the housing chamber to the bottom surface 30 of the charging and power supply unit 12 . Therefore, even if rainwater or the like enters the storage chamber 18, the rainwater is quickly discharged from the discharge passage 82. As shown in FIG.

The portable charging/feeding device 10 according to the present embodiment is basically configured as described above, and the effects thereof will be described next.

When the user wants to move the portable charging and power supply device 10, the user raises the handle 58 around the first rotation shaft to bring it into a grippable state. Thereafter, the user grips the handle 58 and tilts the charging and power supply unit 12 slightly with respect to the ground to move the grounding projections 40a and 40b away from the ground, leaving only the wheels 44a and 44b on the ground. do. Thereafter, when the user walks while holding the handle 58, the wheels 44a and 44b rotate, thereby easily moving the charging/power-supplying unit 12. As shown in FIG.

After the movement of the portable charging and feeding device 10 is completed, the user can turn the handle 58 around the first turning shaft to bring it into the folded state. This makes the portable charging and feeding device 10 compact. That is, the handle 58 is prevented from interfering with any object.

By thus providing the wheels 44a and 44b and the handle 58 to the charging and power feeding unit 12, the portable charging and power feeding device 10 can be easily moved. Moreover, since the handle 58 can be folded, the handle 58 does not become an obstacle after the movement. In addition, the handle 58 in the folded state also serves as a protective member that protects the design surface 14 .

When changing the orientation of the charging and power feeding unit 12, the user may hold the handle 58 and rotate the charging and power feeding unit 12. However, this requires the user to raise his/her arm and then twist it. , the load is relatively large. Also, in a place where there are some objects around, it may be difficult to put the handle 58 in a grippable state. Therefore, the user can insert his finger into the clearance in the grip recess 48 and twist his wrist. In this case, since the center of rotation of the charging and feeding unit 12 is close to the user's body, the load on the user is reduced, and since the handle 58 does not interfere with surrounding objects, the charging and feeding unit 12 can be easily rotated. It has the advantage of being

The portable charging/feeding device 10 can be used in a standing posture by grounding the grounding projections 40a and 40b provided on the bottom surface 30, or can be used in a lying posture by grounding the potches 46a and 46b provided on the back surface 16. It can also be used as a posture. In this way, the portable charging and power supply device 10 can be used at a place of use desired by the user, in a posture corresponding to the installation space of the place of use.

In order to start supplying power, an external device may be electrically connected to the USB terminal 50 or the outlet 52 . In this case, a USB cable may be used to connect the external device to the USB terminal 50 and a commercial power plug may be used to connect to the outlet 52 .

The portable charging and power supply device 10 can be used with the left side surface 34 and the right side surface 36 exposed. It is preferable to install panel 74a. Specifically, the permanent magnet of the entering projection 60 is magnetically attached to the magnetized disk of the receiving recess 76a of the left cover panel 72a and the right cover panel 74a, and the permanent magnet of the magnetically attached projection 78a is attached to the recess 62 to be entered. It should be magnetically attached to the magnetized disk. Thereby, the designability of the portable charging and power supply device 10 is improved.

The head of the mounting screw 66 fits in the vicinity of the opening of the stepped screw hole 64 having a large inner diameter. That is, the head of the mounting screw 66 does not protrude and interfere with the inner surfaces of the left cover panel 72a and the right cover panel 74a.

Here, the attachment of the left cover panel 72a and the right cover panel 74a to the left side surface 34 and the right side surface 36 of the charging and power supply unit 12 is performed via magnetic force as described above. Therefore, it is easy to attach and detach the left cover panel 72a and the right cover panel 74a. Therefore, as shown in FIGS. 7 and 8, the left cover panels 72b and 72c and the right cover panels 74b and 74c can be freely changed in patterns and colors according to the user's preference. Therefore, the design property is further improved.

Alternatively, the left side container 90 and the right side container 92 shown in FIG. In this case, on both the left side surface ( outer surface) and the right side surface ( inside surface) of the left container 90, there are receiving recesses 76b into which the entering protrusions 60 enter, and magnetically attracted protrusions entering into the entering recesses 62. A portion 78b is provided respectively. Furthermore, a screw insertion hole 94 is formed on the inner surface. On both the left side ( inner surface) and the right side ( outer surface) of the one right container 92, there are receiving recesses 76b into which the entering protrusions 60 enter, and magnetic attachments that enter the entering recesses 62. A convex portion 78b is provided and a screw insertion hole 94 is formed on the inner surface.

In this case, first, the mounting screws 66 are removed from the stepped screw holes 64 of the left side surface 34 and the right side surface 36 . After that, the permanent magnet of the entrance convex portion 60 is magnetically attached to the magnetic attachment disc of the receiving recess portion 76b of the left container 90, and the permanent magnet of the magnetic attachment protrusion portion 78b is magnetically attached to the magnetic attachment disc of the entrance recess portion 62. . Further, after passing the screw portion of the mounting screw 66 through the screw insertion hole 94 on the inner surface of the left container 90 , the screw portion is screwed into the stepped screw hole 64 on the left side surface 34 . As a result, the left container 90 is firmly connected to the left side surface 34 via the magnetic force and the mounting screw 66 . Therefore, even when a heavy object such as the spare rechargeable battery 20 is stored in the left container 90 , the left container 90 is prevented from falling off from the left side surface 34 .

Similarly, the permanent magnet of the entrance protrusion 60 is magnetically attached to the magnetic attachment disc of the receiving recess 76b of the right container 92, and the permanent magnet of the magnetic attachment protrusion 78b is magnetically attached to the magnetization disc of the entrance recess 62. do. Further, after passing the screw portion of the mounting screw 66 through the screw insertion hole 94 on the inner surface of the right container 92 , the screw portion is screwed into the stepped screw hole 64 on the right side surface 36 . As a result, the right container 92 is firmly connected to the right side surface 36 via the magnetic force and the mounting screw 66 . Therefore, in the same manner as described above, even when a heavy object such as the spare rechargeable battery 20 is stored in the right container 92, the right container 92 is prevented from falling off from the right side surface 36. .

Although it is possible to use the left side surface 34 and the right side surface 36 with the outer surfaces thereof exposed, the left side surface 34 and the right side surface 36 are each provided with a left cover panel 72a and a right cover panel 74a. You may do so. In this case, the permanent magnets of the magnetically attracted protrusions 78b on the outer surfaces of the left side surface 34 and the right side surface 36 are magnetically attached to the magnetized discs of the receiving recesses 76a of the left cover panel 72a and the right cover panel 74a. The permanent magnet of the portion 78a may be magnetically attached to the magnetized disk of the receiving recess 76b. This improves the design of the portable charging and power supply device 10 including the left container 90 and the right container 92 .

Left bin 90 and right bin 92 are preferably used to store spare rechargeable batteries 20 . This is because the rechargeable battery 20 in the charging and feeding unit 12 can be quickly replaced with a new rechargeable battery 20 after the discharge of the rechargeable battery 20 is completed. When replacing the rechargeable battery 20 in the storage chamber 18 with the spare rechargeable battery 20, the top cover 32 is rotated about the second rotation shaft to open the storage chamber 18. FIG. After that, when the user grips and lifts the grip portion 22 , the rechargeable battery 20 is taken out from the storage chamber 18 .

Of course, the containers 90 and 92 may store any article other than the spare rechargeable battery 20. FIG.

Furthermore, a plurality of portable charging and feeding devices 10 can be placed adjacent to each other and electrically connected to each other. Three cases will be exemplified below, and in order to facilitate distinction of the portable charging/feeding device 10, each of the charging/feeding units 12 shown on the left, center, and right sides of FIGS. They are referred to as a charging and feeding unit 12a, a second charging and feeding unit 12b, and a third charging and feeding unit 12c.

In this case, the right side surface 36 of the first charging/feeding unit 12a, both side surfaces 34 and 36 of the second charging/feeding unit 12b, and the left side surface 34 of the third charging/feeding unit 12c are exposed. Then, the entrance plugs 70 of the first charging and power supplying unit 12a and the second charging and power supplying unit 12b are rotated to protrude from the right side surface 36. As shown in FIG.

Further, the entrance plug 70 of the first charging/feeding unit 12a is inserted into the feeding socket 68 of the second charging/feeding unit 12b, and the entrance plug 70 of the second charging/feeding unit 12b is inserted into the third charging /feeding unit 12c. Insert into the receptacle 68 . At this time, the entering convex portion 60 and the entering concave portion 62 of the right side surface 36 of the first charging and feeding unit 12a are engaged with the entering concave portion 62 and the entering convex portion 60 of the left side surface 34 of the second charging and feeding unit 12b. Also, the entering protrusion 60 and the entering recess 62 on the right side surface 36 of the second charging and feeding unit 12b are engaged with the entering recess 62 and the entering protrusion 60 on the left side surface 34 of the third charging and feeding unit 12c. As a result, as shown in FIG. 11, the first charging/supplying unit 12a to the third charging/supplying unit 12c are connected in parallel. In addition, power can be extracted from the rechargeable battery 20 housed in each storage chamber 18 for the first charging and power feeding unit 12a to the third charging and power feeding unit 12c.

That is, electric power is taken sequentially from, for example, the rechargeable batteries 20 in the first charging and feeding unit 12a to the third charging and feeding unit 12c. Therefore, when a commercial power plug of an external device is inserted into the outlet 52 of the third charging and feeding unit 12c, power is supplied from the rechargeable battery 20 in the third charging and feeding unit 12c to the external device. When the discharge of the rechargeable battery 20 ends, the power supply source is immediately switched to the rechargeable battery 20 in the second charging and feeding unit 12b. immediately switches to the rechargeable battery 20 in the first charging and feeding unit 12a. This switching is an example, and the rechargeable batteries 20 in the first charging and feeding unit 12a, the second charging and feeding unit 12b, and the third charging and feeding unit 12c may be switched in this order.

Alternatively, the rechargeable batteries 20 in the first charging/supplying unit 12a, the second charging/supplying unit 12b, and the third charging/supplying unit 12c may be connected in parallel. In this case, the voltage obtained from three rechargeable batteries 20 is equivalent to the voltage when only one rechargeable battery 20 is used. Therefore, it is possible to avoid excessively increasing the load voltage to the external device.

In either case, it is possible to draw power from three rechargeable batteries 20 . Therefore, it is possible to meet power demand over a long period of time. That is, for example, it can be used safely in areas where long-term power outages occur frequently.

After the discharge of the rechargeable battery 20 is completed, external power can be input to the female connector 80 provided on the right side surface 36 via an AC adapter cord. Thereby, the rechargeable battery 20 is charged through the charging plug. It is also possible to supply power to an external device connected to the USB terminal 50 or the outlet 52 while charging the rechargeable battery 20 .

The present invention is not particularly limited to the above-described embodiments, and various modifications are possible without departing from the gist of the present invention.

For example, in FIG. 11, the left side container 90 containing the auxiliary rechargeable battery 20 is attached to the left side surface 34 of the first charging and feeding unit 12a, and the auxiliary charging type battery is attached to the right side surface 36 of the third charging and feeding unit 12c. A right container 92 containing the battery 20 may be attached.

Further, instead of the foldable handle 58, a retractable handle may be provided.
