DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a secondary battery lock structure, and more particularly to a secondary battery lock structure that does not require an operation such as pressing a lock release button when a secondary battery is removed from a portable telephone.

[0002]

2. Description of the Related Art An example of a conventional secondary battery lock structure will be described with reference to the drawings. FIG. 3 is a plan view showing an example of a conventional secondary battery lock structure, and FIG. 4 is a cross-sectional view showing an operation state of an example of a conventional secondary battery lock structure. The conventional secondary battery lock structure includes a hook 16 for locking the secondary battery 15, a spring 18 attached to a rear portion of the hook 16 for always pushing the hook 16 to the outside of the rear cover 12, and sliding the hook 16. It comprises a button 17 having a tapered portion 17a for releasing the lock, a metal fitting 19 for holding the hook 16 and the button 17 on the rear cover 12, and a screw 20 for fixing the metal fitting 19. The secondary battery 15 is a front cover 13
A locking groove 15b for engaging with a locking claw 14 provided at a rear portion of the vehicle and a concave groove 15a for fitting with a hook 16 are provided.

When the secondary battery 15 is mounted on the rear cover 12, as shown in FIG.
5b is engaged, and the secondary battery 15 is rotated in the direction of arrow A about this point as a fulcrum.
c interferes with the hook 16, and the hook 16 retreats in the arrow B direction. As shown in FIG. 4B, when the secondary battery 15 is set in a predetermined position, the hook 16 is pushed back in the direction of arrow C by the elastic force of the spring 18, and is fitted into the groove 15a. Reference numeral 15 is attached to the rear cover 12.

When the secondary battery 15 is removed from the rear cover 12, when the button 17 is pressed, the tapered portion 17a of the button 17 and the hollow portion 16a of the hook 16 interfere with each other, as shown in FIG. Retreats in the direction of arrow B, the lock is released, and the secondary battery 15 can be removed.

[0005]

A first problem of the prior art is that when the secondary battery is removed from the portable telephone, it takes time to remove the secondary battery. The reason is that an operation such as pressing a lock release button is required.

A second problem is that the cost is high. The reason is that since the number of parts is large, manufacturing costs and assembly man-hours are required.

SUMMARY OF THE INVENTION It is an object of the present invention to remove a secondary battery from a mobile phone without requiring an operation such as pressing an unlock button, thereby making it possible to easily remove the secondary battery.
Another object is to provide a secondary battery lock structure in which the number of parts is reduced and the cost is kept low.

[0008]

According to the present invention, a front cover is provided.
And a secondary battery provided opposite to the front cover.
Secondary battery lock structure of a mobile phone and a rear cover for mounting the has a pair of support shafts for attaching an end of the rear cover, lower than the support shaft is the front
Hooks in the cover, the front cover and the
A leaf spring interposed between the cover and the cover to maintain a locked state, wherein the support shaft is fitted into a notch groove provided at an end of the rear cover , and the leaf spring is provided on the rear cover. contacting the lower portion of the hook and the inner wall surface of the front cover by attached elastic force was rib
Until the locking state is maintained, the secondary battery has a locking recess at the front for engaging with a locking claw provided on the rear cover, and a lock at the rear for fitting with the hook. It is the structure provided with the groove for each.

In this configuration, when the secondary battery is mounted on the rear cover, the locking recess is engaged with the locking claw, and the secondary battery is rotated with the locking recess as a fulcrum. The curved surface of the secondary battery interferes with the hook,
The hook retreats with the support shaft as a fulcrum, and when the rechargeable battery is set in a predetermined position, the hook is pushed back by the elastic force of the leaf spring, and the hook is fitted in the locking groove, A secondary battery is mounted on the rear cover. Further, when the secondary battery is removed by the rear cover, when the secondary battery is pivoted around the support shaft while sliding backward, the hook is retracted and the locked state is released, and the secondary battery is removed. Allows removal.

[0010]

Next, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a perspective view of a secondary battery lock structure according to an embodiment of the present invention. FIG. 2 shows an operation state of the embodiment of the present invention. The secondary battery lock structure includes a hook 3 having a pair of support shafts 3a for attaching to the rear cover 1, and a leaf spring 4 for maintaining the lock. The support shaft 3a is provided with a notch groove 6 provided in the rear cover 1.
The leaf spring 4 is attached to a rib 5 provided on the rear cover 1 and pushes the lower part of the support shaft 3a of the hook 3 by elastic force to rotate the hook 3 in the direction of arrow A to maintain the lock. . The elastic force of the leaf spring 4 prevents the hook 3 from protruding from the rear cover 1, and
Lock 3 is unlocked due to sudden pressure from outside
The lower portion of the support shaft 3 a of the hook 3 is supported by being in contact with the inner wall surface of the front cover 2 so that the hook 3 is attached to the rear cover 1. The rear cover 1 and the front cover 2 are assembled with screws 11. The secondary battery 8 is provided with a locking recess 9 for fitting with the locking claw 7 provided on the rear cover 1 and a locking groove 10 for fitting with the hook 3.

Next, the operation will be described in detail with reference to FIG. When attaching the secondary battery 8 to the rear cover 1,
As shown in FIG. 2 (a), the engaging recess 9 is engaged with the engaging claw 7, and the rechargeable battery 8 is rotated in the direction of arrow B using this as a fulcrum. 8a interferes with the hook 3, and the hook 3 retreats in the arrow B direction with the support shaft 3a as a fulcrum. As shown in FIG. 2B, when the secondary battery 8 is set in a predetermined position, the hook 3 rotates in the direction of arrow A about the support shaft 3a as a fulcrum by the elastic force of the leaf spring 4, and the hook 3 is locked. The secondary battery 8 is fitted to the rear cover 1.

When the secondary battery 8 is to be removed from the rear cover 1, as shown in FIG.
When the hook 3 rotates in the direction, the hook 3 retreats in the direction of arrow B with the support shaft 3a as a fulcrum, the lock is released, and the secondary battery 8 can be removed.

[0014]

The first effect of the present invention is that the secondary battery can be easily removed. The reason is that when removing the secondary battery from the mobile phone, an operation such as pressing an unlock button is not required.

A second effect is that cost can be reduced. The reason is that the number of parts has been reduced.
