Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fixing structure for a battery pack provided as a power source in a portable electronic device, and more particularly to a fixing structure for a battery pack which can be easily attached and detached.

[0002]

2. Description of the Related Art A battery pack in which a rechargeable battery is unitized is often used as a power source of a portable electronic device, and when the battery is exhausted, the battery pack is detached from the portable electronic device body to be charged and repeatedly used.

A conventional battery pack fixing structure will be described with reference to FIGS.

The battery pack 1 is removably provided on the back surface of the electronic equipment main body 2 via a rail (not shown), and is fixedly held by the lock mechanism 3 when attached. When removing the battery pack 1, the lock release button 4 projecting to the back side is pressed and the battery pack 1 is slid.

The lock mechanism 3 will be described with reference to FIG.

A lock member 5 having a crank-shaped cross section has a pin 6
The lock member 5 is rotatably provided, and one end of the lock member 5 protrudes from the back surface of the battery pack 1 and the lock release button 4
The other end projects from the mounting surface 7 of the battery pack 1 to form a locking piece 8. Further, a spring 9 for urging the lock member 5 in a direction in which both the lock release button 4 and the locking piece 8 project is provided.

A recess 10 is formed on the surface of the electronic device body 2 on which the battery pack 1 is attached, and the locking piece 8 is fitted when the battery pack 1 is mounted.

When the battery pack 1 is mounted, the locking piece 8 is fitted into the recess 10 and the spring 9 presses the locking piece 8 into the recess 10. Therefore, the battery pack 1 is mounted. State is retained. Further, when the lock release button 4 is pushed against the spring 9, the lock member 5 rotates, the locking piece 8 is pulled out from the recess 10, and the battery pack 1
Can be removed by sliding.

[0009]

In the above-mentioned conventional battery pack fixing structure for portable electronic equipment, a plurality of parts such as the lock member 5, the pin 6 and the spring 9 are combined,
Since the assembly is complicated and the assembly must be performed in a narrow space, it is complicated and requires careful attention.

In view of the above situation, the present invention is intended to reduce the number of parts and to facilitate the assembling.

[0011]

According to the present invention, a battery pack can be slidably attached to and detached from an electronic equipment body, a latch hole is provided in the electronic equipment body, and a lock member is formed integrally with a case of the battery pack. The elastic member is elastically displaceable, and the lock member is formed with a latch piece engageable with the latch hole and a lock release button protruding from the case of the battery pack.

[0012]

When the battery pack is mounted on the body of the electronic device, the locking member elastically engages the latch piece with the latch hole to fix the battery pack to the body of the electronic device, and a release force is applied to the lock release button to release the latch. The piece comes off the latch hole, and the battery pack can be pulled out from the electronic device body.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a rear view of the portable electronic device, and FIGS. 2 and 3 show the battery pack 11 removed from the electronic device main body 12. The battery pack 11 is an electronic device body 1
It is attachable to and detachable from 2, and is slidably attached via a rail (not shown). Further, a lock mechanism 13 for fixing the battery pack 11 to the electronic device body 12 in a state where the battery pack 11 is completely attached to the electronic device body 12 is provided.

The battery pack 11 is provided with a lock member 14, and the electronic device body 12 is provided with the lock member 1.
There is a latch hole 24 into which 4 is engaged.

The battery pack 11 will be described with reference to FIG.

The battery pack 11 is composed of a rechargeable battery 16, an outer case 17 for accommodating the rechargeable battery 16, and an inner case 18, and the lock member 1 is provided at the front end side of the inner case 18.
4 is integrally formed.

A recess 15 is formed at the tip of the inner case 18, a window 19 is further formed in the recess 15, and the lock member 14 is provided in the window 19. Further, the tip ends of flexible strips 22 extending from the inner case 18 are integrally connected to both ends of the lock member 14, and the lock member 14 is elastically attached to the inner case 18 by the flexible strips 22. It is supported.

The lock member 14 has a lock release button 20 projecting from the outer case 17, and a latch piece 21 extending from the lock release button 20 toward the base end side. It projects from the window 19 toward the electronic device body 12 side.

A convex portion 23 that fits into the concave portion 15 on the battery pack 11 side is formed at the tip of the electronic device body 12, and the convex portion 23 has a latch hole into which the latch piece 21 is engaged. 24 are provided.

The operation will be described below.

First, the battery pack 11 is attached to the electronic device main body 12
It is fitted to a rail (not shown) and slid to the left in the figure (see FIG. 5). When the battery pack 11 is pushed further, the latch piece 21 rides on the convex portion 23, and the flexible strip 22 bends (see FIG. 6).

When the battery pack 11 is completely pushed in, the elasticity of the flexible strip 22 releases the flexure, and the latch piece 21 engages with the latch hole 24. When the latch piece 21 is engaged with the latch hole 24, the movement of the battery pack 11 in the pulling-out direction is blocked, and the battery pack 11 is fixed to the electronic device body 12 (see FIG. 7).

Next, when removing the battery pack 11, the lock release button 20 is pushed. The lock release button 20 rotates clockwise around the edge of the latch hole 24 in FIG.
The latch piece 21 is disengaged from the latch hole 24. The battery pack 11 can be freely slid, and the battery pack 11 can be removed.

The lock release button 20 is provided in the inner case 18
The flexible strip 22 may be omitted, the left end of the lock release button 20 in FIG. 5 may be connected to the inner case 18 via a thin portion, and the thin portion may be hinged. As a matter of course, the lock release button 20 and the latch hole 24 may be appropriately changed in shape.

[0026]

As described above, according to the present invention, since the lock release button is formed integrally with the case, the number of parts is reduced and the assembling work is not required, so that the manufacturing cost and the assembling cost are reduced. Be effective.
