DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a push-up mechanism and a push-up method for a battery pack containing a battery, and more particularly to a push-up mechanism and a push-up method for a battery pack of a small wireless terminal device such as a portable telephone.

[0002]

2. Description of the Related Art Conventionally, as a battery pack lifting mechanism of this type, for example, a claw portion is provided on a lock member incorporated in a housing of a portable telephone, and an engagement groove portion which engages with this claw portion on the battery pack side. By pressing the push button of the lock member and releasing the engagement of the claw portion of the lock member with the battery pack engagement groove portion, the spring repulsive force of the power supply terminal which is the contact portion between the housing and the battery pack is provided. The battery pack is pushed up,
There is known a mechanism capable of easily attaching and detaching a battery pack.

[0003]

A first problem with this conventional battery pack lifting mechanism is that the spring repulsion of a power supply terminal, which is a contact point between the housing and the battery pack, is used to push up the battery pack. Therefore, there are restrictions when designing the structure of the mobile phone, such as the shape and position of the power supply terminal, which hinders the degree of freedom in design.

A second problem is that the spring repulsion of the power supply terminal is used to push up the battery pack. That is, the battery pack is not mechanical.
There is a possibility that the battery pack may not be able to be pushed up due to a variation in fitting between the housing and the battery pack, and the reliability and reliability are lacking.

An object of the present invention is to improve the degree of freedom, reliability and reliability of the design of a portable telephone or the like by mechanically pushing up a battery pack instead of utilizing the spring repulsive force of a power supply terminal. An object of the present invention is to provide a battery pack pushing-up mechanism and a pushing-up method thereof.

[0006]

According to the present invention, there is provided a battery pack lifting mechanism, comprising: a housing having a hole for making contact with a bottom surface of a battery pack for housing a battery; A hook engaged with the hook
And press the hook vertically against the housing.
A push button that slides horizontally to release the lock of the battery pack, and has a protrusion at one end and slides in conjunction with the push button, and the protrusion slides through the hole of the housing. A push-up member for pushing up the bottom surface of the battery pack.

Further, the method for pushing up a battery pack according to the present invention comprises:
Press the button that is engaged with the slot of the battery pack by the spring elastic force in the direction perpendicular to this hook,
The battery pack is slid in the horizontal direction with respect to the housing, and the battery pack is unlocked from the housing, and the push-up member that is linked to the pressing of this button is slid. Of the battery pack push up the bottom surface of the battery pack through the hole of the housing.

In the battery pack lifting mechanism of the present invention, by adding a U-shaped lifting member, the button is pressed to unlock the battery pack from the housing, and at the same time, the button is interlocked with the button via a pin or a spring pin. Since the push-up member slides on a wall or a convex surface of the housing to mechanically push up the battery pack, the shape and position of the power supply terminal can be freely designed, and reliability and reliability are also improved. improves.

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

FIG. 1 is a partial external view of an embodiment of the present invention, showing a state in which a battery pack 12 is hooked and fitted to a battery pack hooking portion 19 of a casing 15 of a portable telephone or the like. I have. Referring to FIGS. 2 to 4, the battery pack pushing-up mechanism includes a battery pack 12 for storing batteries.
15 having hole 17 for contacting the bottom surface of
A hook 7 engaged with the slot 16 of the battery pack 12 by a spring elastic force; a push button 1 for sliding the hook 7 by pressing to release the lock of the battery pack 12; And a U-shaped push-up member 5 that has a portion 14 and slides in conjunction with the push button 1 so that the protrusion 14 pushes the bottom surface of the battery pack 12 through the hole 17 of the housing 15.

The details of the lifting mechanism will be described below with reference to FIGS. Push button 1 incorporated in housing 15
The mounting wall 2 has a through hole 3 which is joined to a lifting member 5 having a through hole 4 via a pin 6 or a spring pin (not shown). Further, the through hole 8 of the hook 7 comes into contact with the inclined surface 10 of the projection 9 of the push button 1 and slides in conjunction with the push button 1. At this time, as shown in FIG. 3, the hook 7 is incorporated in the housing 15 so that the spring 11 can slide on the surface of the cap 18 by the cap 18.

Further, the lower end of the battery pack 12 is
The battery pack 12 is dropped from above, the battery pack 12 is mounted, the hook 7 is engaged with the slot 16 of the battery pack 12 and locked by the housing 15, and the push button 1 is in the pushed-up state. Has become. As a result, the push-up member 5 joined to the push button 1 operates in the direction of the arrow or in the opposite direction in conjunction with the push button 1, and when the lock of the battery pack 12 is released as shown in FIG. When the push button 1 is pressed, the hook 7 interlocks with the push button 1, slides on the cap surface in the Z direction, disengages from the battery pack 12, and is unlocked.

The push-up member 5 interlocked with the push button 1 is pressed against the housing surface 13 by pressing the push button 1 and slides on the housing surface in the direction of the arrow Y. Projecting from the hole 17 of the battery pack 12 to push up the bottom surface of the battery pack 12 attached to the housing, so that the battery pack 12 can be easily removed.

Next, the details of the lifting operation will be described with reference to FIGS. The push button 1 is pushed in to remove the battery pack 12 from the housing 15. By this pressing, the spring 1
Hook 7 constantly pressed in Y direction by 1
The hook 7 slides in the Z direction when the inclined surface 10 of the convex portion 9 of the push button 1 comes into contact with the through hole 8 of the hook 7, and the engagement with the battery pack 12 is released. At the same time, the push-up member 5 joined to the push button 1 via the pin 6 (or the spring pin) has a plane parallel to the housing surface with respect to the pressing direction of the push button 1 and contacts the housing surface 13. When the push button 1 is pressed, the push button 1 is pressed against the housing surface 13 and slides in the Y direction with the pin 6 as an axis. As a result, the protrusions 14 of the push-up member 5 protrude from the holes 17 on the housing surface, and push up the bottom surface of the battery pack 12 attached to the housing 15.

[0015]

As described above, according to the present invention, the first advantage is that the push-up mechanism of the battery pack is interlocked with the hook release mechanism, so that the shape and position of the power supply terminal are not restricted and the structural design can be reduced. The degree of freedom can be expanded. The reason is that the battery pack is pushed up mechanically without using the springy elastic force of the power supply terminal.

The second effect is that, by pushing up the battery pack without using the power supply terminal, the battery pack is affected by the power supply terminal, the weight of the battery pack, and the variation in fitting between the housing and the battery pack. The battery pack can be pushed up without using it, and reliability and reliability can be improved. The reason is that the battery pack is pushed up mechanically without using the springy elastic force of the power supply terminal.
