Abstract

PROBLEM TO BE SOLVED: To double a battery capacity and enable various power controls by detecting a battery lock state interlocked with a lock means of a battery provided at the battery storage part by means of a sensor switch. SOLUTION: When the tip end parts of batteries 3 and 4 come into contact with the tip end of a lever 6, the lever 6 rotates clockwise against the energizing force of a coil spring 7, moves a lever 6, and a slider 10 of the lever 6 moves in the left direction. By means of the slider 10, a sensor switch 11 is constituted so that the switch can detect that either of batteries 3 and 4 is inserted into a battery insertion part 2 of a cabinet 1. When either of these batteries 3 and 4 is inserted into the battery insertion part 2, a tip end 12 of the lever 6 fits into a notch 13 of a battery 3 or 4, therefore, the lever 6 rotates with its center being a shaft 14 and is locked in the battery storage part 2.

2. Description of the Related Art A notebook type PC using a conventional liquid crystal panel
Alternatively, in the WP, the built-in battery uses only one pack in order to reduce the size and weight.

However, with this configuration, the power consumption of the electronic device main body has increased, and the capacity of one battery has become insufficient.

[0004]

DISCLOSURE OF THE INVENTION The present invention has a drawback in the above-mentioned conventional example, that is, a countermeasure when one battery is insufficient is insufficient, and in particular, a structure for efficiently detecting the presence or absence of the battery is provided. To aim.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings.
FIG. 2 is a plan view of the small electronic device main body showing the battery lock detecting device for a small electronic device according to the present invention, and FIGS.

In the drawings, 1 is a cabinet of a small electronic device, 2 is a battery housing, 3 is a first battery, 4 is a second battery, 5 is a connecting pin for each battery, and 6 is an unlocking device. Lever, 7 is a torsion spring that gives a clockwise rotating force to the lock lever, 8 is a cam,
Reference numeral 9 is a compression spring that applies a biasing force to the cam in the right direction in the drawing,
Reference numeral 10 is a slider provided on the cam, 11 is a sensor switch that operates according to the movement of the slider, 12 is a tip portion of the lever, 13 is a notch, and 14 is a pusher of the sensor switch.

The mechanism of the device of the present invention will be described below. First, when the first battery 3 or the second battery 4 is mounted from the cabinet 1 taken out of the apparatus main body 1, there is no battery, and the lever 6 is twisted. In FIG. 4 showing a state in which the spring 7 is urged counterclockwise, the battery 3 or 4 is mounted in the battery housing 2 in the device body cabinet 1.

The tip of the battery 3 or 4 is the lever 6
When the lever 6 comes into contact with the tip of the lever 6, the lever 6 rotates clockwise against the urging force of the torsion spring 7 and becomes the state shown in FIG.
Move the lever 7 to the left in the drawing to move the slider 10 of the lever 6.
Moves to the left.

Along with this, the sensor 10 is electrically connected to the sensor switch 11 by the slider 10 when either the first or second battery 3 or 4 is attached to the battery insertion portion 2 of the main body cabinet 1. The configuration can be detected.

After this, when the battery 3 or 4 is completely attached to the battery insertion portion 2 in the equipment main body cabinet 1, the tip portion 12 of the lever 6 is the first battery 3 or the second battery.
4 into the notch 13 of the battery 4, the lever 6 is pushed by the torsion spring 7 as shown in FIG.
Rotates counterclockwise around the center of the first or second battery 3 or 4 and is locked in the battery housing 2 of the listening main body cabinet 1.

On the other hand, the case of removing the battery 3 or 4 from the battery insertion portion 2 will be described. The lever 6 is operated outside the equipment main body cabinet 1 from the state of FIG. The part 12 is pushed upward in the drawing.

As a result, the tip portion 12 of the lever 6 is shown in FIG.
2 is disengaged from the notch 13 of the battery 3 or 4, and the lever 6 is disengaged from the battery 3 or 4 in the state of FIG. 2, the battery 3 or 4 can be taken out from the battery storage portion 2 of the equipment main body cabinet 1. You can

Along with this, a slider 10 provided on the cam 8
2 shifts from the state shown in FIG. 3 to the state shown in FIG. 2, the pusher 14 of the sensor switch 11 moves leftward, and it is electrically detected that the battery is taken out.

At this time, if a detection signal is applied to the power supply control circuit, various controls can be performed. For example, the first battery 3 is housed in the battery housing section 2 in the main body cabinet 1, and the second battery 4 is installed. As described above, when the battery is taken out from the battery storage unit 2, the connection state of the battery can be switched accordingly.

[0016]

According to the battery lock detecting device for a small electronic device of the present invention, a plurality of batteries can be housed in the device body cabinet as compared with the conventional case where the internal circuit is driven by a single battery pack. Since the battery capacity can be doubled and the sensor switch is activated according to the attachment / detachment of the battery, various kinds of power control can be performed, and the device of the present invention exerts an extremely great effect on small electronic devices. it can.
