The first problem is that, in the above-mentioned prior art, even if it is desired to keep the battery in a locked state, there is a possibility that the lock is released by an accidental external force.

The reason for this is that the holding force for locking the battery depends on the elastic force of the coil spring. Increasing the elastic force of the coil spring increases the holding power of the battery, but there is a possibility that a conflicting problem that the button becomes difficult to press when removing the battery may occur.

[0006] The second problem is that in the above-mentioned conventional technique, the battery is difficult to remove and the design is restricted.

[0007] The reason for this is that a design having a body and a battery connected in a smooth three-dimensional shape does not have a gripping portion for the battery, so that a concave portion, a non-slip, or the like must be provided on the side surface.

An object of the present invention is to improve the above-mentioned problems of the prior art, to withstand accidental external force, to have a strong battery lock holding force, and to easily attach / detach a battery even with a three-dimensional curved surface or a smooth surface. It is to provide a structure.

[0009]

SUMMARY OF THE INVENTION Accordingly, the present invention solves the above-mentioned problems of the prior art, in which the holding force of the battery is not affected by the elasticity of the spring, and when the battery is taken out, the button is depressed. The lock is released and the battery is exposed from the main body.

[0010] For this purpose, the battery detachable structure of the present invention comprises a main body for detachably holding the battery, a hook member provided on the main body for engaging and locking the battery, and a movement of the hook member when the battery is locked. And a button member which is moved by a press against the elastic force of the spring member to release the engagement lock of the hook member, wherein the holding force of the battery lock acts on the button member. Is not affected by the elastic force of

In this battery attaching / detaching structure, the hook member has an operation plate that is rotatable about a lower portion of the hook and extends in two directions from the fulcrum, and one of the operation plates is the button member. When pressed by the push-down movement, the battery lock by the hook is released, and the other operation plate pushes up the battery to be exposed from the main body. The hook has a hole into which a rib protruding from the back surface enters, and the hole is provided with a tapered portion that matches the tangent of the rotational movement of the hook member.

More specifically, the movement of the hook engaging with the battery is not a conventional slide movable type, but has a structure in which the hook is rotatable about a fulcrum. The hook is integrally movable and moves in two directions from the center of the fulcrum. An extended working plate is provided, with one working plate located below the button and the other working plate located below the battery. When the button is in the battery lock state, the button is disposed on the movable portion of the hook, and when the button is pressed, the button is released from the movable portion of the hook, and the hook is made movable and the action plate is pressed down at the same time.

According to such a structure, when the button is pressed down, the button becomes a point of emphasis and pushes down the action plate.
Since the hook can be moved about the fulcrum, the battery lock is released, and the other operation plate disposed below the battery serves as an operation point, and the battery can be exposed to the outside from the main body by the leverage principle. .

Further, when the battery is mounted on the main body, the hook and the battery are engaged, and the position of the button is disposed on the movable portion of the hook. Is in an appropriate engagement lock state.
