Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a battery box of a device such as a camera and a video device which uses a plurality of batteries such as a main battery and a backup battery.

[Conventional technology]

Conventionally, generally in the battery box of this kind of equipment,
Each battery was stored in its own dedicated battery compartment.

Therefore, we will put multiple batteries in the same battery compartment,
Only one cover is required if the maximum size of the above-mentioned batteries can be taken in and out, and if the partition or locking member of each battery is not required, the batteries can be closely arranged side by side. Since it can be accommodated as a whole, the internal space becomes smaller. In addition, it is desirable that the electronic room is waterproof,
In recent years, a battery box having a waterproof structure, which is advantageous in terms of the number of parts, has been proposed.

[Problems to be solved by the device]

However, in the battery box as described above,
Since there is no partition or locking member between the batteries, there is a fear that if one battery is taken out, the remaining batteries will suddenly come out of the mounting position.

The present invention has been made in view of this problem, and an object of the present invention is to obtain a battery box having a battery chamber in which all the batteries can be housed in the same chamber without affecting other batteries even if one battery is taken out. To aim.

[Means for solving problems]

A battery box according to the present invention includes a battery storage chamber having first and second storage parts connected to each other and capable of storing a first battery and a second battery, respectively. A common outlet for discharging the second battery, and a second position that does not lock the second battery in the battery storage chamber when the first battery is discharged from the battery storage chamber And a locking member that is displaced to the first position to prevent the second battery from falling off from the battery storage chamber. is there.

[Action]

As in the above configuration, "a battery storage chamber having first and second storage portions connected to each other capable of storing a first battery and a second battery" and "from the battery storage chamber to the first,
Since a common discharge port for discharging the second battery is provided, the entire battery storage chamber can be provided as compared with the case where the first and second storage parts are not connected to each other or the discharge port has separate discharge ports. It can be significantly downsized.

However, it has the above-mentioned battery storage chamber and a common discharge port, and the first and second storage parts are connected, but "while detecting the discharge of the first battery from the battery storage chamber, In accordance with the detection, a locking member that displaces the second battery in the battery storage chamber from the second position where the second battery is not locked to the first position where the second battery is locked is provided, so that the first battery is discharged. In doing so, the second battery will not fall out.

〔Example〕

 An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, which shows a main part of this embodiment in a diffusion diagram, 1 is a main battery, 2 is a backup battery, and 21 and 22 are abutted on the back surface (left side in the drawing) and side surface of the battery 2, respectively. Contact piece 3
Is a drop-out prevention lever (hereinafter referred to as "D lever") for preventing the backup battery 2 from falling off. The "mold locking portion 3k" is locked to the top surface 1c of the main battery 1 at the upper center of the main body 3h of the horizontally long rectangular plate. And project a pair of protrusions 3t on the upper side of both sides of the main body 3h.
Is formed. 4 has the upper end locked to the protrusion 3t and is D
A lever coil 3 is a tension coil spring that projects the lever 3 into the open / close opening 62a of the battery chamber 62 of the backup battery 2 and urges it in the blocking direction. The lower end of the lever 3 is fixed to the housing portion outside the lower end of the open / close opening 62a. I am doing it. 5 is the access port
62a A pair of guides of the D-lever 3 which are erected parallel to the outside on both sides, engage the protrusions 3t with the guide grooves 5m formed on the opposite side surfaces to slide the D-lever 3 up and down. .

FIG. 2 is a vertical cross-sectional view of the battery chamber 6 showing a battery mounted state.

In order to mount the battery, first, the locking mechanism (not shown) is released to open the battery lid 7, and the D lever 3 which always shuts off the loading / unloading opening 62a is changed from the state shown by the chain double-dashed line to the operating member (not (As shown), or by pushing up with a finger against the pulling force of the tension coil spring 4 to open the loading / unloading port 62a and pushing the battery 2 into the battery chamber 62 of the backup battery 2, it is provided on the side wall of the battery chamber 62. Since the spring force of the contact piece 22 presses it against the other side wall to fix it, when the finger that is pushed up is released, the restoring force of the coil spring 4 causes the D lever 3 to move in and out again.
Cut off 62a.

Next, the top surface 1c of the main battery 1 is pushed into the battery chamber 61 of the main battery 1 against the tension of the tension coil spring 4 with the top surface 1c abutting against the die locking portion 3k. After the conical coil spring 8 attached to the inner wall is compressed and pushed forward, the battery cover 7 is closed and locked to complete the battery mounting as shown in Fig. 2. Opening / closing structure of the battery cover 7 In addition, since the locking mechanism is usually used in cameras, a description thereof will be omitted here.

Since both the batteries 1 and 2 are housed in the battery chamber 6 in the above-mentioned state, when the locking of the battery lid 7 is released, the main battery 1 is removed from the battery chamber 61 by the restoring force of the conical coil spring 8. Third
Since it is discharged as shown in the figure, "the die locking portion 3k becomes free, and the D-lever 3 is pulled back by the tension coil spring 4 to automatically shut off the loading / unloading opening 62a again.

Therefore, the backup battery 2 cannot be discharged unless the D-lever 3 is retracted from the inlet / outlet opening 62a by an artificial operation, and it is possible to prevent accidental dropping.

Needless to say, when it is necessary to take out the backup battery 2 for replacement or the like, the operation is reversed when the battery is mounted.

In addition, in the above-described embodiment, an example of the structure in which the D-lever blocks the inlet / outlet opening of the battery is shown. Good.

[Effect of device]

As described above, the present invention provides a "battery storage chamber having first and second storage parts connected to each other capable of storing a first battery and a second battery", and "from the battery storage chamber to the Common outlet for discharging the first and second batteries "
Since the battery storage device is provided, it is possible to significantly reduce the size of the entire battery storage chamber as compared with a storage device in which the first and second storage portions are not connected to each other and a storage device having separate discharge ports.

Then, although the first and second storage parts are connected, "from the second position where the second battery in the battery storage chamber is not locked with the discharge of the first battery from the battery storage chamber" A locking member that displaces to the first position for locking is provided, and the second battery does not drop out when the first battery is discharged. It is possible to store multiple batteries without providing a partition
A number of effects can be obtained, such as saving the battery storage space, making the battery compartment lid identical, and reducing the number of waterproof structure parts.
