Abstract

PURPOSE: To provide a lock structure between an electronic equipment main unit and a battery unit wherein the structure is simplified by decreasing the number of part items to facilitate assembling and replacing work. CONSTITUTION: A lock member 3 integrally molded by an elastic material is provided between a main unit 1 and a battery unit 2 mounted on this main unit. When the battery unit 2 is mounted on the main unit 1, a respective stop part 12 and stopped part 22 are hooked, with this part serving as the support point, when the battery unit 2 is turned in a direction C, a lock movable part 31 of the lock member 3, fixedly fitted to an engaging hole of the main unit 1, is distorted by elasticity, and a tapered protrusive part 31a and a lock inserting recessed part 21 are engaged to be locked, to fix the battery unit 2. At removal time, when a lock knob 33 connected to the lock movable part 31 is pressed in a direction A, the lock movable part 31 is moved in a direction B, to perform unlocking, so that the battery unit 2 can be removed.

Description

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,
Particularly, with regard to a lock structure for mounting a battery or the like on a portable electronic device, one member having elasticity is used for locking and releasing the lock.
The present invention relates to an electronic device lock structure having two functions.

[0002]

2. Description of the Related Art Conventionally, as shown in FIGS. 3 and 4, a lock structure for an electronic apparatus of this type is composed of a lock button 61, a hook 62, a spring 63, and a holding metal fitting 64. When mounting and attaching the battery unit 5 to the main body unit 4, the battery unit 5 is attached to the locking portion 42 of the main body unit 4.
After hooking the locked portion 52 of the hook, 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 resists the spring 63 and the arrow D.
When the hook 62 and the lock insertion recess 51 are aligned with each other, the hook 62 returns to its original position by the force of the spring 63, and the battery unit 5 is fixed. When removing
When the lock button 61 is pushed in the direction of arrow E with a finger, the hook 62 moves in the direction of arrow D in conjunction with this, 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. Also, the hook 62 is a holding metal fitting 64.
The movement in the arrow E direction is restricted by.

[0003]

In the conventional lock structure for electronic equipment, when the battery unit is mounted and fixed to the main body unit, four parts, that is, a lock button, a hook, a spring, and a metal fitting are required. Therefore, the assembly / replacement work is not easy, and the large number of parts affects cost reduction and product miniaturization.

The object of the present invention is to eliminate the above-mentioned drawbacks of the prior art and to replace the conventional four parts with a simple structure.
The purpose is to provide a lock structure for electronic equipment covered by one component.

[0005]

According to another aspect of the present invention, there is provided a lock structure for an electronic device, comprising a lock structure for removably locking a battery unit to a main body of the electronic device, at one end of each of the main body and the battery unit. A first locking portion which is locked to each other and serves as a rotation fulcrum of the battery unit, and a locking member made of a material having elasticity on each side facing the one end side of the main body and the battery unit. Secondly intervening to lock and lock the main body and the battery unit
The locking member is fitted to the second locking portion of the main body, and the elastic member is attached to the second locking portion of the rotating battery unit. And a knob portion which is connected to the movable portion to release the engagement lock.

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 sectional view of this embodiment when locked.

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 side and two engaging holes 11 at a substantially central portion facing the one end side. 1 and a locked portion 2 which is detachable from the main body unit 1 and which is locked to a locking portion 12 on one end side to serve as a rotation fulcrum.
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 body unit 1 and the other end side of the battery unit 2 at the end of rotation. It

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 which has a tapered convex portion 31a at its tip and moves in conjunction with the lock knob 33. And a lock holding portion 34 that connects the lock knob 33 and the lock movable portion 31 to each other and movably holds them, and has key-like engagement claws 32 that fit into the engagement holes 11 of the main body unit 1 at both ends. It consists of Therefore, by fitting the engagement claw 32 of the lock member 3 into the engagement hole 11 of the main body unit 1, the main body unit 1 and the lock member 3 are detachably fitted and fixed.

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

When the battery unit 2 is mounted and attached to the main body unit 1, the locking portion 12 of the main body unit 1 is hooked on the locked portion 22 of the battery unit 2, and the battery unit 2 is shown with this portion as a pivot. 2 is rotated in the direction of arrow C, and the lock insertion concave portion 21 is gradually pushed into the main body unit 1, so that the lock movable portion 31 of the lock member 3 fitted and fixed to the main body unit 1 is elastically bent and arrowed. The tapered convex portion 31 of the lock movable portion 31 is pushed in the B direction.
When the position of "a" and the position of the lock insertion recess 21 are aligned, the lock movable portion 31 returns to its original position by its elastic force and engages and locks in the lock insertion recess 21, and the battery unit 2 is inserted through the lock member 3 into the main body. It is fixed to the unit 1. When the lock knob 33 is pushed with a finger in the direction of the arrow A when the battery unit 2 is removed, the lock movable portion 31 moves in the direction of the arrow B in conjunction therewith, and the lock insertion recess 21 of the battery unit 2 is moved.
Then, the engagement lock is released and the battery unit 2 can be removed from the main body unit 1.

In the above-described embodiment, the engaging hole 11 and the engaging claw 3 are used for fitting and fixing the main unit 1 and the lock member 3.
Although 2 is used as an example, the present invention is not limited to this, and other structures that can similarly be fitted and fixed may be used.

[0013]

As described above, according to the lock structure of the electronic device of the present invention, the structure which has conventionally required four parts is detachably fitted and fixed to the main unit made of an elastic material and the battery unit is engaged. It is possible to cover with a single part called a lock member that movably engages and locks with the part due to its elasticity, and because the structure is simple, it is possible to easily assemble and replace, it is possible to reduce costs and downsize products. effective.
