The present invention relates to a battery storage device.

Hereinafter, a case where an embodiment of the battery storage device of the present invention is implemented in a battery-powered shaver will be described with reference to the drawings.

The battery storage device of the present invention has a U-shaped cross section and has an opening 3 on one side that allows AA batteries 1 and AA batteries 2 to be taken in and out as needed to form a battery storage body 4. A motor 11 has a contact 6 in contact with the anode 5 of the AA battery 1 and a contact 8 in contact with the anode 7 of the AA battery 2 at one end, and drives the inner blade of the cutting part 10 of the shaver body 9. One input contact 12
an anode terminal 14 having a contact portion 13 in contact with the
, and has a contact piece 16 in contact with the cathode 15 of the AA battery 1 and a contact piece 18 in contact with the cathode 17 of the AA battery 2 at the other end of the battery housing 4, and a shaver main body. A cathode terminal 21 having one end thereof has a contact part 20 which is connected in contact with the other input contact 19 of the motor 11 that drives the inner blade of the cutting part 10 of the battery storage body 4, and the other end of the battery storage body 4 has an elastic material. A suitable number of locking pieces 23 each having a locking convex portion 22 are provided, and a storage section 24 into which the battery storage body 4 is inserted and stored is provided in the shaver main body 9. AA type pressing rib 25 for pressing the side surface of the AA type battery 2 against the battery housing 4; and AA type pressing rib 26 for pressing the side surface of the AA type battery 2 against the battery housing 4.
The locking protrusions 22 of an appropriate number of locking pieces 23 of the battery storage body 14 are provided at the end 27 of the shaver body 9.
It is constructed by providing an appropriate number of locking recesses 28 for locking.

In the above structure, the shaver main body 9 is formed so that it can be divided into both sides at the center, and the contact piece 1
Reference numerals 6 and 18 are made of a monolithic spring material or the like.

Next, to explain the usage status of the battery storage device configured as described above, first, when using AA batteries, insert the AA batteries 1 into the battery storage 4 through the opening 3 of the battery storage 4. The anode 5 of the AA battery 1 is connected to the contact 6 of the anode terminal 14 of the battery housing 4.
At the same time, the cathode 15 is brought into contact with the contact piece 16 of the cathode terminal 21 of the battery housing 4, and the battery housing 4 is placed in the housing 24 of the shaver body 9. 1 is inserted into the battery housing 4 so as to be pressed by the AA pressing rib 25 of the housing 24, and the contact part 6 of the anode terminal 14 and the contact part 20 of the cathode terminal 21 of the battery housing 4 are inserted. are connected to one input contact 12 and the other input contact 19 of the shaver main body 9, and the locking protrusions 2 of an appropriate number of locking pieces 23 of the battery storage body 4
2 to an appropriate number of locking recesses 28 of the shaver main body 9.
The motor 11 of the shaver body 9 is energized from the AA battery 1 of the battery housing 4, and the battery housing 4 is attached to the housing 24 of the shaver body 9. In this case, the AA battery 1 is inserted into the AA battery pressing rib 25 of the storage section 24 of the shaver main body 9.
Since the AA battery 1 is pressed against the battery accommodating body 4, the AA battery 1 is reliably held in a predetermined state without wobbling.

Next, when using the AA battery 2, place the AA battery 2 into the battery housing 4 through the opening 3 of the battery housing 4, and insert the anode 7 of the AA battery 2 into the battery housing 4. At the same time, the cathode 17 is brought into contact with the contact piece 18 of the cathode terminal 21 of the battery housing 4, and the battery housing 4 is placed in the housing 24 of the shaver body 9. The AA batteries 2 stored in the battery storage body 4 are placed in the storage part 2.
4, and connect the contact portion 13 of the anode terminal 14 and the contact portion 20 of the cathode terminal 21 of the battery housing 4 to one input contact 12 and one of the input contacts 12 of the shaver body 9. While making contact connection with the other input contact 19, the locking protrusions 22 of the appropriate number of locking pieces 23 of the battery storage body 4 are locked into the appropriate number of locking recesses 28 of the shaver body 9, and the battery The motor 11 of the shaver main body 9 is energized from the AA battery 2 of the storage body 4, and the battery storage body 4 is attached to the storage portion 24 of the shaver main body 9. In this case, the AA battery 2 is pushed into the battery housing 4 by the AA battery pressing rib 26 of the housing 24 of the shaver body 9.
Since the AA battery 2 is pressed by the AA battery 2, the AA battery 2 is reliably held in a predetermined state without wobbling.

In addition, in the above explanation, the anode 5 of the AA battery 1
A contact 6 that contacts the AA battery 2 and a contact 8 that contacts the anode 7 of the AA battery 2 are individually provided on the anode terminal 14, and a contact piece 16 that contacts the cathode 15 of the AA battery 1 and a contact piece 8 that contacts the anode 7 of the AA battery 2 are provided. The case has been described in which the contact pieces 18 that contact the cathode 17 are individually provided on the cathode terminal 21, but the contacts that contact the anode 5 of the AA battery 1 and the anode 7 of the AA battery 2 are provided on one anode terminal. 14 and the cathode 15 of the AA battery 1
Also, a contact piece that contacts the cathode 17 of the AA battery 2 may be formed as a single cathode terminal 21.

Since the battery storage device of the present invention has the above-described configuration, it can store AA batteries, which have almost the same length,
The anode and cathode terminals can be easily and reliably contacted with the anode and cathode of AA batteries without using auxiliary electrodes and without changing the insertion position, and can also be used with AA batteries and AA batteries. AA batteries and AA batteries can be stored securely in a narrow space, and the AA and AA batteries can be stored selectively in the battery compartment using the AA battery pressing rib on the inner surface of the storage compartment, and the AA battery pressing rib on the inside of the storage compartment. The battery compartment can be held securely without wobbling with the protective ribs, and the battery compartment can be easily attached to the compartment with the locking mechanism, making it easy to replace AA and AA batteries. Furthermore, the battery storage device can be formed compactly.
It is possible to obtain an optimal small battery storage device that appropriately uses AA batteries and AA batteries for small electrical equipment.
