DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lock structure for electronic equipment,
In particular, the present invention relates to a lock structure for mounting a battery or the like on a portable electronic device.
The present invention relates to a lock structure of an electronic device having two functions.

[0002]

2. Description of the Related Art Conventionally, a lock structure of an electronic device of this type includes a lock button 61, a hook 62, a spring 63, and a holding metal fitting 64, as shown in FIGS. When the battery unit 5 is mounted and attached to the main unit 4, the battery unit 5
After the locked portion 52 is hooked, the lock insertion concave portion 51 is gradually pushed into the main body unit 4 by rotating as shown by the arrow F, so that the hook 62 is opposed to the spring 63 by the arrow D.
The hook 62 returns to the original position by the force of the spring 63 when the position of the hook 62 and the lock insertion concave portion 51 match, and the battery unit 5 is fixed. When removing,
When the lock button 61 is pressed by a finger in the direction of arrow E, the hook 62 moves in the direction of arrow D in conjunction with the push, and the hook 62 is disengaged from the lock insertion recess 51 of the battery unit 5, and the battery unit 5 can be removed. The hook 62 is provided with a holding metal fitting 64.
The movement in the direction of arrow E is restricted by the arrow.

[0003]

In this conventional lock structure for electronic equipment, when a battery unit is to be mounted and fixed on a main unit, four parts, a lock button, a hook, a spring, and a holding metal, are required. As a result, the assembling / replacement work is not easy, and the large number of parts has had an effect on cost reduction and product miniaturization.

SUMMARY OF THE INVENTION An object of the present invention is to eliminate the above-mentioned conventional drawbacks, and to replace the conventional structure requiring four parts with a simple structure.
An object of the present invention is to provide a lock structure of an electronic device that can be covered by three components.

[0005]

A lock structure for an electronic device according to the present invention is a lock structure for detachably locking a battery unit to a main body of the electronic device, wherein one end of each of the main body and the battery unit is provided. interposing a first locking portion that becomes the rotation fulcrum of the battery unit engaged with each other, a locking member made of an elastic material at the one end side and love against that side of the battery unit and the main body It is not made and a second locking portion for locking the lock and the battery unit and the main body, wherein the locking member includes a portion fitted and fixed to the second engaging portion of said body, said locking member Intervening
For each side of the main body and the battery unit
A movable portion which is elastically deformed in a substantially vertical direction and is locked by being bent and locked by the elasticity with the second locking portion of the battery unit rotating;
Elastically deformed substantially parallel to the back surface, and the movable portion
And a knob that is connected via a fulcrum of the material to release the engagement lock.

[0006]

Next, the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view of an embodiment of the present invention before locking, and FIG. 2 is a cross-sectional view of the embodiment when locking.

As shown in FIGS. 1 and 2, the lock structure of this embodiment has a main body unit having a locking portion 12 at one end and two engagement holes 11 at a substantially central portion facing the one end. 1 and a locked part 2 which is detachable from the main body unit 1 and is locked at one end by a locking part 12 to be a pivot point.
2 and a battery unit 2 having a lock insertion recess 21 on the other end side, and a lock member 3 interposed between the central portion of the main unit 1 and the other end side of the battery unit 2 at the end of rotation. You.

The lock member 3 is formed by integrally molding an elastic material such as plastic, and has a lock knob 33 and a lock movable portion 31 having a tapered convex portion 31a at the tip and moving in conjunction with the lock knob 33. A lock holding portion 34 which has a lock-shaped engaging claw 32 on both side ends, which movably holds the lock knob 33 and the lock movable portion 31 by being connected thereto and which fits into the engagement hole 11 of the main body unit 1; Consists of Therefore, the main unit 1 and the lock member 3 are removably fitted and fixed by fitting the engagement claws 32 of the lock member 3 into the engagement holes 11 of the main unit 1.

The operation of this embodiment having such a configuration will be described.

When the battery unit 2 is mounted and attached to the main unit 1, the locked portion 22 of the battery unit 2 is hooked on the locking portion 12 of the main unit 1, and the battery unit 2 is illustrated with this portion as a pivot point. 2, the lock insertion recess 21 is gradually pushed into the main unit 1, whereby the lock movable portion 31 of the lock member 3 fitted and fixed to the main unit 1 is flexed by the elasticity so that the arrow is drawn. Pushed in the direction B, the tapered convex portion 31 of the lock movable portion 31
When the position of the lock insertion recess 21 matches the position of the lock insertion recess 21, the lock movable portion 31 returns to its original position by its elastic force, engages with the lock insertion recess 21, and locks the battery unit 2 through the lock member 3. It is fixed to the unit 1. When the battery unit 2 is removed, when the lock knob 33 is pressed with a finger in the direction of arrow A, the lock movable portion 31 moves in the direction of arrow B in conjunction with the push, and the lock insertion recess 21 of the battery unit 2 is moved.
The battery unit 2 is detached from the main unit 1 and the engagement lock is released.

In the above-described embodiment, the engagement hole 11 and the engagement claw 3 are used for fitting and fixing the main body unit 1 and the lock member 3.
2 is used, but the invention is not limited to this, and another structure that can be similarly fitted and fixed may be used.

[0013]

As described above, the lock structure of the electronic device according to the present invention, which has conventionally required four parts, is made of an elastic material so as to be removably fitted to and fixed to the main unit and to engage with the battery unit. The part can be covered by a single member, a lock member that movably engages and locks due to its elasticity, and the structure is simple, so that it can be easily assembled and replaced, cost reduction and product miniaturization are possible. effective.
