Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a lock structure of a battery pack used for a portable telephone or the like.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 5, a lock structure of a battery pack used in this type of portable telephone is easily held in a battery storage section 31 provided on a back surface of a main body 3 so as to be easily attached and detached. When the pack 4 is mounted, the battery storage 31
The engaging claw 32 provided at the rear end of the battery pack 4 is engaged with the locking groove 41 on the rear end side of the battery pack 4, and the battery pack 4 is rotated by using this as a fulcrum to lock the battery pack 4 in the locking groove 42. The battery pack 4 is locked by engaging the hook portion 34 of the knob 33.

The lock knob 33 is inserted through a spring into a lock knob storage recess provided in the main body 3 and is constantly pushed toward the battery pack 4 so that the lock knob 33 does not protrude from the storage recess in the main body. And is slidably accommodated in the battery accommodating portion 31 in the direction of the battery accommodating portion 31.

[0004]

In the conventional battery pack holding structure described above, the lock knob can always slide in the battery pack direction even when the battery pack is mounted.
If the lock knob is depressed due to an impact when dropped or carried, or due to erroneous operation during use,
The battery pack could come off.

It is an object of the present invention to provide a battery pack lock structure of a portable telephone which easily prevents the battery pack from coming off, thereby preventing erroneous operation when the battery pack is mounted and improving reliability.

[0006]

According to the present invention, there is provided a battery pack lock structure for a mobile phone, wherein a locking groove at a rear end of the battery pack is provided on an engagement claw at a rear end of a battery storage portion provided on a back surface of the mobile phone. After the engagement, the battery pack is rotated around the fulcrum, and the hook portion of the lock knob is engaged with the locking groove of the battery pack to lock the battery pack. A lock knob slidable in the battery pack direction by an urging force, and a stopper knob movable to first and second positions in a direction perpendicular to the battery pack direction within a stroke in which the lock knob slides. The lock knob is slidable when the stopper knob is at the first position, and the lock knob is slidable when the stopper knob is at the second position. Are as hereinbefore order to impossible, also the stopper knob has a flexible pawl, said first
When moving between the second position and the second position, the pawl receives a click-stop resistance.

More specifically, a lock knob that slides in the direction of arrow A via a spring (19 in FIG. 2) at the front end of the battery housing (11 in FIG. 1) to lock the battery pack (2 in FIG. 1). (13 in FIG. 1) and a stopper knob (15 in FIG. 1) that slides in the direction of arrow B within the stroke in which the lock knob (13) slides. When the battery pack (2) is attached to the battery storage section (11), the stopper knob (15) is moved on the sliding stroke of the lock knob (13) and fixed, so that the lock knob (15) slides. Is suppressed, and the battery pack (2) is held.

[0008]

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

FIG. 1 is an external perspective view showing an embodiment of the present invention, FIG. 2 is an exploded perspective view showing a battery pack locking mechanism in FIG. 1, and FIG. 3 is a sectional view showing an engaged state of a lock knob in FIG. FIG. 4 is a plan view showing the use state of the stopper knob in FIG.

In this embodiment, as shown in FIGS. 1 and 2, a battery housing 11 is engaged with a main body 1 of a portable telephone, and a locking groove 21 at a rear end of a battery pack 2 is engaged with a rear end thereof. It has an engaging claw 12 and a lock groove 22 of the battery pack 2 at the front end.
Storage recess 14a for storing lock knob 13 that engages with
, A recess 14b for accommodating the stopper knob 15, and a fitting hole 17a. A lock knob 13 for mounting and locking the battery pack 2 is inserted into the storage recess 14a via a spring 19, is mounted on the main body 1 over the projection 18 for preventing the battery pack 2 from slipping off, and slides in the direction of arrow A which is the battery pack direction. Stored as possible. Within the sliding stroke of the lock knob 13, the stopper knob 15
Is movably fitted in a fitting hole 17a of the concave portion 14b in a direction of an arrow B perpendicular to the arrow A by a flexible snap-fitting claw 16 provided on the bottom surface. Mating hole 1
7a has a convex portion 17b at the center thereof, and the stopper knob 15 has a click 16 that moves over the convex portion 17b so that a click stop resistance is provided at either the right or left position in the fitting hole 17a. It is designed to be received and held.

In the configuration of the present embodiment,
When the battery pack 2 is mounted on the main body 1, the locking claw 12 at the rear end of the main body 1 is engaged with the locking groove 21 at the rear end of the battery pack 2, and the battery pack 2 is rotated around the fulcrum to rotate the battery pack 2. Hook 1 of lock knob 13 in lock groove 22 of pack 2
3a is engaged, and the battery pack 2 is mounted.

When the battery pack 2 is removed, the lock knob 13 is pressed down against the spring 19 to the rear of the arrow A to release the engagement between the locking groove 22 of the battery pack 2 and the hook portion 13a of the lock knob 13. The stopper knob 15 slides left and right when the claw 16 passes over the convex portion 17b provided at the center of the fitting hole 17a of the main body 1, and is held at the left and right positions. The snap-fit claw 16 of the stopper knob 15 receives a click-stop resistance when going over the convex portion 17b, and cannot be easily moved from left to right or right to left by natural force alone.

When the battery pack is mounted, the stopper knob 15
Is located on the right side (FIG. 4-a), the lock knob 1
Reference numeral 3 normally slides in the direction of arrow A, and the battery pack 2 can be attached and detached as described above. When the position of the stopper knob 15 is moved in the direction of arrow B and held on the left side (FIG. 4-b),
Since the lock knob 13 is disposed on the sliding stroke of the lock knob 13, the lock knob 13 corresponds to the stopper knob 15,
Since the battery pack 2 is fixed at that position, the battery pack 2 is held without coming off.

[0014]

By using the battery pack lock structure of the present invention, the stopper knob suppresses the sliding of the lock knob, so that the battery pack can be easily held and the detachment of the battery pack due to erroneous operation is prevented. be able to.
