2. Description of the Related Art Regarding a conventional battery pack lock structure,
The case of being used for a mobile terminal such as a mobile phone will be described below. 3A and 3B are views showing an example of a conventional battery pack lock structure, FIG. 3A is a perspective view showing a state in which the battery pack is removed, and FIG. 3B is a vertical cross-sectional view near the center of the lock structure. In FIG. 3A, the lock knob 10 is arranged at the center of the upper side of the battery pack 20, and the main body 3 of the mobile terminal.
It is slidably locked and fixed to the back of No. 0. Here, a lock portion 17 is provided on the lower side of the lock knob 10, and a concave portion 2 engaged with the lock portion 17 is provided on the upper side of the battery pack 20.
Have one. Further, in FIG. 3B, a coil spring 4 for maintaining a locked state is provided between the lock knob 10 and the main body 30.

When removing the battery pack 20, first, the lock knob 10 is slid in the direction of arrow A with the finger of one hand to unlock. Then, while holding the lock knob 10 in that state, hold the vicinity of C on the side surface of the battery pack 20 with the finger of the other hand and pull up in the direction of the arrow B, and further hold the claw portion 22 on the lower side of the battery pack of the main body 30. The battery pack 20 is removed from the recess 32. A technique similar to the above-mentioned lock structure is disclosed in Japanese Patent Laid-Open No. 10-64493.

[0004]

The above-mentioned conventional battery pack lock structure has the following problems. The first problem is that the battery pack cannot be removed smoothly. The reason is that when removing the battery pack from the mobile terminal, slide the lock knob with one finger of the hand to unlock it, and while holding the lock knob in that state, use the finger of the other hand to lock the lock knob on the side of the battery pack. This is because the part C must be lifted and the fingers of both hands must be operated. The second problem is that the lock structure has a large number of parts. The reason is that a coil spring is required in addition to the lock knob.

An object of the present invention is to provide a battery pack lock structure and a battery pack removing method, which are capable of smoothly unlocking, lifting the battery pack, and removing the battery pack with a small number of parts and fingers of one hand. And to provide a mobile terminal.

BEST MODE FOR CARRYING OUT THE INVENTION Next, a first embodiment of the present invention will be described with reference to the drawings.

Referring to FIG. 1, there is shown an example of a mobile terminal using a battery pack lock structure for mounting and fixing the battery pack of the present invention on the mobile terminal, wherein (a) shows a state in which the battery pack is removed. It is a perspective view, (b) is an exploded perspective view of the lock structure vicinity, (c) is an assembly perspective view of the lock structure vicinity. As shown in FIG. 1A, the present invention includes a main body 3 of a mobile terminal and a battery pack 2 to be attached to and used in the main body 3.
And a lock knob (lock means) 1 for fixing the battery pack 2 to the main body 3.

Here, the push-down portion 15 of the lock knob 1 is arranged at the upper portion of both side surfaces of the battery pack 2 in the longitudinal direction to be lifted when removing the battery pack. FIG. 1A shows an example in which the pressing portion 15 has three convex portions on its surface, but the purpose is to prevent slippage during operation, and this surface portion may be a concave surface or a corrugated surface. You may The lock portion 11 is provided directly below the push-down portion 15, and the battery pack 2
Is to be locked in the recess 31 of the main body 3 of the portable terminal. Further, on both sides of the lower side of the battery pack, there are claw portions 22 that are locked and fixed in the concave portions 32 of the main body 3.

In FIG. 1B, the lock knob 1 is
The push-down portion 15, the lock portion 11, the arm portion 13 that is directly connected to the lock portion 11 and locks the battery pack 2, the hole 14 that positions the lock knob 1 for attaching to the battery pack 2, and the arm portion 13. And a hole 14 provided between the hole 14 and the hole 14 to maintain the lock portion 11 in a locked state, and these portions are integrally formed of a flexible material. As the flexible material, for example, polyacetal (abbreviation POM) or polycarbonate (abbreviation PC) is suitable. Here, the lock knob 1 is
A symmetrical shape is formed around the hole 14.

Further, a taper surface 16 is provided at the tip of the lock portion 11 so that the lock portion 11 can be easily inserted into the main body 3. Further, the battery pack 2 includes a hook portion 23 for locking the arm portion 13 of the lock knob 1 and the lock knob 1.
The hole 14 has a boss 24 for positioning the fitting lock knob 1. Here, the hook portion 23 has a shape capable of sliding in the pressing direction of the lock knob 1.

The lock knob 1 and the battery pack 2 having the above construction are assembled in the form shown in FIG. 1 (c) and ready for use. In the present embodiment, the case where the lock knob 1 including the spring portion 12 is integrally formed of the same material has been described, but a metal elastic member may be used for this spring portion and the lock knob 1 may be integrated by insert molding.

Next, the operation of removing the battery pack according to the first embodiment will be described with reference to the drawings. In FIG. 1A, first, the pressing portion 15 of the lock knob 1
When is pressed in the direction of arrow A, the lock portion 11 is disengaged from the recess 31 of the main body 3 and unlocked. Although not shown, the lock structure is symmetrical with respect to the center of the battery pack 2 in the longitudinal direction, and the opposite side is simultaneously released by the same operation. Then, while pushing down the pushing portion 15, the pushing portion 15 is pulled up in the direction of the arrow B, and the claw portion 22 on the lower side of the battery pack is further depressed in the recess 3
2 and remove the battery pack 2.

The operation of attaching the battery pack 2 is basically the reverse of the operation of removing the battery pack 2. However, even if the pressing portion 15 of the lock knob 1 is not pressed, the battery pack 2 itself is in the opposite direction of arrow B. It can be attached by pressing. This is because the tapered surface 16 is provided so as to easily enter the tip of the lock portion 11.

Next, a second embodiment of the present invention will be described with reference to the drawings.

FIG. 2 is a perspective view showing the form of the lock knob according to the second embodiment of the present invention. In FIG. 2, the difference from the first embodiment is the shape of the spring portion 12a of the lock knob 1a, and other configurations and effects are the same as those of the first embodiment, so description thereof will be omitted. . In this way, the shape of the spring portion can be arbitrarily selected to be S-shaped as in the first embodiment or U-shaped as in the second embodiment according to the convenience of mounting. Is.

[0022]

As described above, according to the present invention, the first effect is that the battery pack can be smoothly removed, and the commercial property can be improved. The reason is,
By arranging the operation part of the lock knob, which is a locking means, at the part to lift when removing the battery pack, both the operation of pushing the lock knob to unlock and the operation of grasping and lifting the battery pack can be done with only one finger This is because it has such a structure. The second effect is that the lock structure of the battery pack can be realized with a small number of parts and the cost of parts and assembly can be reduced. The reason is that the lock knob is integrally formed of a flexible material.
