DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic device such as a portable telephone, and more particularly to a battery attaching / detaching mechanism used in the electronic device.

[0002]

2. Description of the Related Art Heretofore, this kind of battery attaching / detaching mechanism has been used for the purpose of attaching / detaching a battery used as a power supply in a small electronic device such as a portable telephone from the electronic device.

FIGS. 2A and 2B are cross-sectional views showing an example of a conventional battery attaching / detaching mechanism. FIG. 2A is a diagram showing a state in which a battery is locked, and FIG. 2B is a diagram showing a state in which the battery is unlocked. It is. Referring to FIG. 2, the battery attaching / detaching mechanism includes a front-side housing 1 that detachably holds a battery 30.
0 and a back surface side housing 20, a hook 50 urged by a spring 53 to engage with the battery 30 to lock the battery 30, and a hook 50 for releasing the battery 30 from the locked state. Button 40.

The lower side of the front side housing 10 has a convex portion 11 that engages with a concave portion 31 formed in the battery 30, and a hook 52 that engages with a lock hole 32 of the battery 30 has a claw 52 Having. The hook 50 is installed on the inner surface of the back side housing 20 in such an arrangement that a spring 53 is passed through the support shaft 51 and the button 40 and the tapered portion provided on each of the hooks 50 are in contact with each other. It has a structure in which the hook 50 interlocks.

The operation will be described below. When the battery 30 is mounted on the rear side housing 20 and is in a locked state, FIG.
As shown in (a), since the convex portion 11 is engaged with the concave portion 31 and the lock hole 32 is engaged with the claw 52 of the hook 50, the battery 30 is not detached from the rear side housing 20.

On the other hand, when the battery 30 is detached from the housing, the hook 50 is slid by pressing the button 40 as shown in FIG.
After being disengaged from the battery, the battery 30 is grasped by hand, and the battery 30 is taken out while rotating the battery 30 around the convex portion 11.

[0007]

The above-mentioned conventional battery attaching / detaching mechanism has a design in which a battery is difficult to grasp when the battery has a curved surface or a smooth surface, and therefore, a non-slip or the like is provided at a place where the battery is grasped. There is a problem that there is a possibility that the battery design is restricted, such as being indispensable.

An object of the present invention is to provide a battery attaching / detaching mechanism capable of easily attaching / detaching a battery having a curved surface or a smooth surface from a housing in which the battery is housed.

[0009]

According to the present invention, there is provided a battery attaching / detaching mechanism, comprising: a housing for detachably holding a battery; an elastic member protruding from a battery insertion surface of the housing; battery engaging comprises a hook that the battery in a locked state, and a button for releasing the battery from the locked state, the elastic member, before

To protrude. Further, the housing may be provided with an auxiliary member for changing a projecting position of the elastic member on a battery insertion surface.

According to the present invention, the cushion is provided between the housing and the battery, and when the battery and the housing are in the locked state, the cushion is sandwiched between the two and crushed. When the locked state is released by pressing the button in this state, the battery slightly projects from the housing by the elastic force of the cushion. Furthermore, when the hand is released from the button, a hook that slides by the elastic force of the spring is used, and this hook scoops up the bottom surface of the battery and projects the battery from the housing to a position where the battery can be easily removed.

[0011]

Next, embodiments of the present invention will be described with reference to the drawings. FIGS. 1A and 1B are cross-sectional views showing a battery attaching / detaching mechanism of the present invention. FIG. 1A is a diagram showing a state in which a battery is locked, FIG. 1B is a diagram showing a state in which the battery is unlocked, and FIG. () Is a diagram showing a state in which the battery has begun to float, and (d) is a diagram showing a state in which the battery has completely protruded.

Referring to FIG. 1, the battery attaching / detaching mechanism includes:
A housing composed of a front-side housing 10 and a back-side housing 20 for detachably holding the battery 30; a cushion 60 protruding from the battery insertion surface of the back-side housing 20;
A hook 50 urged by the battery 30 to engage with the battery 30 to lock the battery 30;
And a button 40 for releasing 0 from the locked state.

A cushion 60 made of an elastic member such as rubber or an elastomer is installed on the battery insertion surface of the back side housing 20 so as to be sandwiched between the battery 30 and the battery 30 in this case. The groove 33 is formed so as to engage with the groove 60. This groove 33 does not necessarily need to be provided.

Other than the above, the structure is the same as that of the prior art, so that the description is omitted.

The operation will be described below. When the battery is pushed into the back side housing 20 and is in the locked state, FIG.
As shown in (a), the convex portion 11 and the concave portion 31, the lock hole 3
Since the hook 2 and the claw 52 at the tip of the hook 50 are engaged with each other, the battery 30 is in a state where it cannot be detached from the back side housing 20. At this time, the cushion 60 is sandwiched between the battery 30 and the back side housing 20 and is in a crushed state.

Next, when the battery lock is released by pressing the button 40, as shown in FIG.
The battery 30 starts to protrude due to the elastic force of the cushion 60, and the battery 30 starts to float as shown in FIG. 1C.

When the hand is released from the button 40, FIG.
As shown in (d), the hook 50 slides toward the battery 30 due to the elastic force of the spring 53, so that the claw 52 scoops up the bottom surface of the battery 30, and further protrudes the battery 30 to a position where the battery can be easily taken out. It is made to protrude from the back side case 20. The extent to which the battery 30 protrudes can be adjusted by the elastic force of the cushion 60, the installation position, the shape of the groove 33, and the like.

In this embodiment, the mounting position of the cushion 60 has been described as being provided at a predetermined fixed position. However, the mounting position can be changed to a protruding degree according to the user's preference.
This cushion 6 is attached to the battery insertion surface of the backside housing 20.
It may be configured to include a member such as an auxiliary metal fitting for changing the zero protruding position.

[0019]

As described above, according to the present invention, a housing for detachably holding a battery, an elastic member projecting from the battery insertion surface of the housing, and a battery urged by a spring. A hook for engaging and locking the battery; and a button for releasing the battery from the locked state.
Sometimes it is pinched between the battery and the housing
When the button is pressed and the locked state is released.
Battery protrudes from the housing by the elastic force of the elastic member
The hook will release the spring when the hand is released from the button.
Slide by the force of the battery and scoop up the bottom of the battery.
Make the battery protrude from the housing to a position where it can be easily removed.

As a result, the battery protrudes and is easily taken out. Even if the battery has a curved surface or a smooth surface, it is not necessary to provide a non-slip rib or the like for taking out the battery by hand. The design is not subject to design restrictions. In addition, since it is only necessary to install an elastic member on the battery insertion surface of the housing, a complicated structure is not required, and it can be realized simply and inexpensively.
