Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a battery lock device for wireless devices and the like, and more particularly to a battery lock device for preventing accidental removal of a battery or a battery pack.

2. Description of the Related Art In recent years, various electric appliances have been miniaturized, and the appearance has been reviewed as an important factor.In consideration of safety, it is necessary to miniaturize and consider the appearance of the battery lock device. Has become.

The conventional battery lock device will be described below. FIG. 4 is a side view of a conventional battery lock device. Reference numeral 1 denotes a battery lid, which contacts the battery 6 via a battery contact rib 24 attached to the battery lid. The battery 6 is inserted into the battery case 7, and the battery lock spring 25 is attached to the battery case 7. Further, the battery 6 is provided with a recess 26 into which the battery lock spring 25 is inserted.

The operation of the battery lock device configured as described above will be described below.

When the battery cover 1 is closed, the battery 6 has a battery contact rib 24.
It is pressed down and fixed by the battery lid 1 via.

On the other hand, when the battery cover 1 is removed, the battery 6 tries to come out of the battery case 7 by turning the set upside down or by the action of a spring or the like. When the battery lock spring 25 comes into contact with 27, the stop action acts elastically. This action prevents the battery 6 from being accidentally dropped and damaged. To take out the battery 6, the bottom 28 of the battery 6 is grasped and pulled out.

The problem to be solved by the invention is that, in the conventional configuration, a large load acts on the battery lid 1 when it is dropped or the like, and therefore it is necessary to have a considerably strong structure. Further, the battery 6 must also be provided with the recess 26.

The present invention solves the above-mentioned conventional problems, and provides a battery lock device in which a large load does not act on the battery lid 1 even when it is dropped and the battery 6 does not need to have a recess. With the goal.

Means for Solving the Problems The battery lock device of the present invention is characterized in that an L-shaped lock piece made of an elastic material is attached to a battery case, and a claw for fitting with the lock piece is provided on the battery lid. To do.

Action With this configuration, almost no large load due to falling etc.
It is supported by a lock piece of shape, and only a slight side relief force acts on the battery lid via the claw. Therefore, the battery lid is lightweight,
Alternatively, the battery can be made into one that emphasizes the appearance, and the outer shape of the battery can be made simple.

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

1 and 2 are a side view and a front view of a battery lock device according to an embodiment of the present invention, respectively. Also,
FIG. 3 is a three-dimensional view of the configuration of this embodiment.

In FIGS. 1 and 2, reference numeral 1 is a battery lid, and a battery contact plate 2 is attached to the back side thereof. In this embodiment, the battery cover 1 is made of aluminum and the battery cover plate 2 is made of stainless steel. The battery cover plate 2 has a claw 3 and a battery cover claw 17
Is provided. On the side surface of the battery case 7, a battery case fixing portion 11 which is inclined at an angle with respect to the battery 6 is provided, and a battery lock piece 5 which is an L-shaped piece of a resin molded product is attached thereto. The battery lock piece 5 is provided with a battery contact portion 9 and a battery support portion 10. When the bottom corner of the battery 6 is restricted by these two surfaces at the same time, the contact 15 of the battery 6 has a spring-like battery terminal. 16 is configured to be conductive. Further, an insertion R portion 14 is provided on the top of the battery lock piece 5.

When the battery lid 1 is closed, the claw 3 is fitted with the fitting portion 8 provided on the battery lock piece 5. At this time, the battery lid 1 is restricted by the outer cabinet 4 from moving forward, backward, leftward and rightward.

The battery case 7 is provided with a fitting portion 18 at a position where the battery lid claw 17 is fitted, and the battery lid 1 is provided with a battery lid lock claw 12 which is fitted to the right frame 19, a battery lid knob 20 and a locking screw. It is attached by 22. Battery lid lock claw 21
Is fixed to the battery lid knob 20 so as to be allowed to rotate with respect to the battery lid 1, and is configured so that the fitting with the right frame 19 can be released by rotating 90 degrees.

The operation of the battery lock device of the present embodiment configured as above will be described below.

The battery lock piece 5 is biased and abutted against the end portion 13 of the battery case 17 when the battery 6 is not inserted.
In the state where the battery 6 is inserted, the battery 6 is pressed by the elastic force of the spring portion 12 via the battery contact portion 9 while being separated from the end portion 13 of the battery case 17, and at the same time, the battery support portion 10 prevents the battery 6 from coming off. There is. Further, when the battery lid 1 is closed, the battery lock piece 5 is restricted in lateral displacement by the claw 3 provided on the battery contact plate 2 attached to the battery lid 1 at the fitting portion 8 thereof. At this time, the battery lid 1 is restricted by the outer cabinet 4 from moving forward, backward, leftward and rightward.

To fix the battery lid 1 to the set, first insert the battery claw 17 into the fitting portion 18, and with this point as a fulcrum, close the battery lid 1 and insert the battery lid lock claw 21 into the hole provided in the right frame 19. After that, by rotating the battery cover knob 20 by 90 degrees, the battery cover lock claw 21 is fixed to the inside of the frame right 19.

When removing the battery 6, after removing the battery lid 1, a finger is put on the insertion R portion 14 to open the battery lock piece 5. When inserting the battery 6, due to the effect of the insertion R portion 14, the battery lock piece 5
Is pushed open by the battery 6 and closed by its own spring force at the end of insertion.

As described above, according to the present embodiment, the claws provided on the battery contact plate regulate the battery lock piece, which is an L-shaped piece made of an elastic material, so that even if a large load such as a drop is applied, the load is reduced. Is mostly carried by the battery lock piece, and only a slight lateral force acts on the battery lid. For this reason, in this embodiment, since the battery lid is light and the design is important, the battery lid may be made of an aluminum plate and a thin stainless plate capable of withstanding a lateral force may be attached to the inside thereof.

Therefore, not only the degree of freedom in design is expanded, but also the structure of the battery lock piece can be formed in a simple and thin shape, which is a great contribution to downsizing of the set and cost reduction.

Further, in this embodiment, the insertion R portion is provided on the lock piece to greatly improve the insertability of the battery, and the battery contact portion is provided to directly press the battery from the side, so that the play between the battery and the battery case is prevented. The discomfort caused by the above can be eliminated, and moreover, the battery supporting portion whose length is limited to make it thin can be effectively used up to the root. In addition, since the battery lock piece is already urged to the end of the battery case from the state where the battery is not inserted, the battery can be pressed from the side with sufficient force when the battery is inserted. Further, with the battery inserted and the battery lock piece bent, the battery contact portion and the battery support portion need to hit the battery side surface and the battery bottom surface substantially in parallel, respectively. By obliquely attaching the battery lock piece to the case, the shape of the battery lock piece can be prevented from becoming complicated, and the cost can be reduced.

As described above, according to the present invention, the lock piece made of the elastic material is attached to the battery case, and the claw provided on the battery lid attached to the battery case is fitted to the lock claw. The battery can be reliably prevented from coming off when the battery lid is closed, and the battery can be prevented from coming off by the lock piece when the battery lid is opened.
