Description

TECHNICAL FIELD The present invention relates to a battery unit for using a secondary battery (rechargeable battery) that can be used repeatedly by recharging in place of a primary battery used as a power source for electronic equipment and electronic devices.

Dry batteries, which are primary batteries, are widely used as power sources for various electronic devices and devices. In recent years, the use of secondary batteries instead of primary batteries has been recommended in consideration of environmental loads such as resource saving and recycling.

However, secondary batteries (for example, nickel-metal hydride batteries) have a nominal voltage of 1.2 V compared to 1.5 V, which is the nominal voltage of dry batteries. However, it may not work properly due to insufficient voltage.

Therefore, for example, Patent Document 1 describes a battery case having a switching mechanism for sharing a primary battery and a secondary battery of the same shape with different output voltages. In this patent document 1, a switch that automatically short-circuits the electrodes by detecting the space created when the secondary battery is used and is automatically opened when there is no need for short-circuiting is installed in the housing of the electronic equipment to be used. is set in

FIG. 2 is a schematic configuration diagram extracting a battery housing part and its surroundings of a laser marking device to which a battery unit according to an embodiment of the present invention is applied; FIG. 2 shows a configuration example of a dummy battery in the battery unit shown in FIG. 1, where (a) is a perspective view of the dummy battery and (b) is a cross-sectional view of the dummy battery. and a sectional view.

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

FIG. 1 shows a schematic configuration by extracting a battery compartment of a laser marking device and its surroundings as an example of an electronic device to which a battery unit according to an embodiment of the present invention is applied.

Electronic equipment such as a laser marking device often uses a plurality of dry batteries connected in series as a power supply, and the battery is consumed quickly because the power supply continues to be on (ON) all day long. Therefore, it is suitable for using the battery unit of the present invention.

That is, the battery unit 10 is "n-1" mounted in the battery housing portion 11a of the electronic device (laser marking device) 11 operated by n (in this example, n=4) primary batteries connected in series. (three) secondary batteries 12-1, 12-2, 12-3, a dummy battery 13 mounted in the battery housing portion 11a of the electronic device 11, and a voltage for adjustment (for voltage compensation) on the dummy battery 13 and two secondary batteries 12-4 and 12-5 mounted in the battery box 14. The battery box 14 applies to the dummy battery 13 a voltage generated by connecting the secondary batteries 12-4 and 12-5 in series. The battery box 14 is externally mounted in an empty space where the electronic device 11 can be operated and carried without any trouble.

The dummy battery 13 has the same shape and size as the primary battery, and has first and second electrodes at positions corresponding to the positive and negative electrodes, respectively. The battery box 14 applies voltage from the secondary batteries 12-4 and 12-5 to the first and second electrodes of the dummy battery 13 through lead wires (power wires) 15-1 and 15-2. The secondary batteries 12-1, 12-2, 12-3 and the secondary batteries 12-4, 12-5 have the same shape and size as the primary batteries, and the secondary batteries 12-4, 12-5 are voltage regulated. is for

The sum of the output voltages of the secondary batteries 12-1, 12-2, 12-3 and the output voltages of the secondary batteries 12-4, 12-5 for voltage adjustment is the output of n primary batteries connected in series. It is set to be approximately equal to the voltage.

If the primary battery is a manganese dry battery or alkaline dry battery, the secondary battery is a nickel-cadmium battery or a nickel-metal hydride battery, and the electronic device 11 operates at a power supply voltage of 6.0 V, for example, "1.5 V x 4 (primary battery)=1.2V×5 (secondary battery).

Therefore, when three secondary batteries are installed in the electronic device 11 and two secondary batteries are installed in the battery box 14, the voltage value of the primary battery and the voltage value of the secondary battery become equal.

Similarly, in the case of an electronic device that operates at a power supply voltage of 12.0 V, 1.5 V x 8 (primary batteries) = 1.2 V x 10 (secondary batteries), so the electronic device has 7 batteries. When three secondary batteries are installed in the battery box 14, the voltage value of the primary battery and the voltage value of the secondary battery become equal.

2A and 2B respectively show configuration examples of the dummy battery 13 in the battery unit shown in FIG. (a) is a perspective view of the dummy battery 13, and (b) is a sectional view of the dummy battery 13. As shown in FIG.

First and second electrodes 13b and 13c (thumb tacks, flat countersunk screws, etc. may be used as long as they are conductors) are attached to both ends of a dummy housing (made of wood, resin, etc.) 13a having substantially the same shape and size as the primary battery. One ends of lead wires (power supply wires) 15-1 and 15-2 are electrically connected to each of the first and second electrodes 13b and 13c.

The other ends of these lead wires 15-1 and 15-2 are connected to the battery box . When the secondary batteries 12-4 and 12-5 are mounted in the battery box 14, the adjustment voltages of these secondary batteries 12-4 and 12-5 are applied to the first and second electrodes 13b and 13c of the dummy battery 13. is applied to the electronic device 11 from .

As described above, according to the battery unit according to the present invention, the output voltage of the secondary batteries 12-1, 12-2, and 12-3 attached to the battery housing portion 11a of the electronic device 11 and the secondary battery for voltage adjustment Since the sum of the output voltages of 12-4 and 12-5 is set to the output voltage of n primary batteries connected in series, even if secondary batteries are used in place of the primary batteries, voltage shortage does not occur. Equipment and devices can be operated normally.

In addition, while using the battery housing portion 11a of the electronic device 11, the battery box 14 having the voltage adjusting secondary batteries 12-4 and 12-5 mounted thereon can be externally attached, so the number of external batteries is minimized. Since it is not necessary to attach a large battery case to the housing of the electronic device 11, deterioration of portability and operability can be suppressed.

It should be noted that the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the invention.

For example, although a laser marking device has been described as an example of an electronic device, it is of course possible to apply the same to any device that operates with a plurality of primary batteries connected in series.

In addition, the sum of the output voltage of the secondary battery mounted in the battery compartment of the electronic device and the output voltage of the secondary battery for voltage regulation was set to the output voltage of n primary batteries connected in series, but it is not necessarily perfect. , and may be adjusted to a voltage within the allowable operating range of the electronic device.

In place of the primary battery used as a power source for various electronic devices and devices, the present invention can use a secondary battery (rechargeable battery) that can be used repeatedly by recharging. It can reduce the environmental load and is industrially useful.
