Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a battery pack and a battery storage mechanism for a portable electronic device.

[0002]

2. Description of the Related Art A portable electronic device such as a notebook personal computer has a built-in battery, and can be used for a fixed time by a battery pack without connecting the device to an AC power supply. The usable time of a device using a battery has been prolonged due to a reduction in power consumption of a portable electronic device and an improvement in the life of a battery pack.

[0003]

A battery pack is stored in a battery storage section of a device. However, a portable device may be accidentally dropped by a user and may give a shock to the device. When a shock is applied to the device, a force acts in a direction in which the battery pack stored in the battery storage portion pops out, so that the battery pack pops out of the device and data stored in a memory or the like built in the device. May be lost. Therefore, there is a need for a battery storage mechanism that has a simple structure and that can reliably hold the battery pack inside the device even when an impact is applied.

Further, when inserting the battery pack into the battery housing, the user may inadvertently insert the battery pack with the polarity reversed, and if the user does not notice the erroneous insertion, the power is turned off. Data in memory may be lost. Further, there is also a problem that the battery pack is short-circuited when a terminal of the battery pack touches a metal or the like.

[0005] It is an object of the present invention to realize a battery storage mechanism capable of securely holding a battery pack inside a device even when an impact is applied. Another object is to prevent the battery pack from being inserted with the wrong polarity.

[0006]

According to the first aspect of the present invention,
A battery storage mechanism for storing a battery pack,
A concave portion into which the convex portion of the battery pack is inserted is provided on a surface facing the terminal of the battery pack, and a battery cover for covering the battery pack with the battery pack housed inside the device is provided.

According to the present invention, even when a drop impact or the like is applied, the convex portion provided on the end face of the battery pack engages with the concave portion on the device side, and the battery pack is held inside the device. Therefore, it is possible to prevent the battery pack from jumping out of the device.

According to a second aspect of the present invention, there is provided a battery housing mechanism for housing a battery pack, wherein a convex portion of the battery pack is inserted into a surface facing a surface opposite to a surface on which terminals of the battery pack are provided. A concave portion is provided, and an elastic member that presses the convex portion of the battery pack in the concave direction is provided on a surface facing the terminal of the battery pack.

According to the present invention, the convex portion provided on the end face of the battery pack engages with the concave portion on the device side, and the convex portion of the battery pack is pressed toward the concave portion on the device side by the elastic member. Therefore, even when a drop impact or the like is applied, it is possible to prevent the battery pack from jumping out of the device.

According to a third aspect of the present invention, there is provided a battery storing mechanism for storing a battery pack, wherein a first concave portion into which a first convex portion of the battery pack is inserted is provided on a surface of the battery pack facing a terminal. A second concave portion into which the second convex portion of the battery pack is inserted is provided on a surface opposite to the surface on which the first convex portion is provided, and a second concave portion of the battery pack is provided on the surface provided with the first concave portion. An elastic member for pressing the second convex portion in the direction of the second concave portion is provided, and the first and second convex portions on both end surfaces of the battery pack are inserted into the first and second concave portions facing each other, thereby mounting the battery pack. It is configured to be stored inside the device.

According to the present invention, the first and second convex portions provided on both end surfaces of the battery pack engage with the corresponding first and second concave portions on the device side, and furthermore, the battery member is provided with an elastic member. The second convex part of the pack is pushed into the second concave part on the device side. Therefore, even if a drop impact or the like is applied, the convex portion of the battery pack is engaged with the concave portion on the device side, so that the battery pack can be prevented from jumping out of the device.

According to a fourth aspect of the present invention, there is provided a battery storing mechanism for storing a battery pack, wherein a first concave portion into which a first convex portion of the battery pack is inserted is provided on a surface of the battery pack facing a terminal. A second concave portion into which the second convex portion of the battery pack is inserted is provided on a surface facing the surface on which the first concave portion is provided, and a second concave portion of the battery pack is provided on a surface provided with the first concave portion. An elastic member that presses the convex portion of the battery pack in the direction of the second concave portion is provided, and one end of a battery cover that covers the battery pack is openably and closably supported while the battery pack is housed inside the device. It is configured to provide a convex portion in the vicinity.

According to the present invention, the first and second projections provided on both end faces of the battery pack are provided on the device side with the corresponding first and second projections.
And when the battery cover is closed, the second protrusion of the battery pack is brought into contact with the second side of the device by the projection provided near one end of the battery cover.
And the backlash of the battery pack in the horizontal direction is reduced, for example, so that the battery pack does not easily jump out of the battery storage mechanism even if a drop impact or the like is applied.

The engagement of the concave portions on the side can prevent the battery pack from jumping out of the device. In addition, since the protruding portion of the battery pack protrudes from the upper end surface of the terminal, it is possible to prevent the surface on which the terminal is provided from coming into contact with metal or the like to short-circuit the battery pack. Further, since the shape of the convex portion of the battery pack is asymmetric with respect to the cross section passing through the central portion of the battery pack, the battery pack cannot be inserted into the battery storage mechanism with the polarity reversed. Thereby, erroneous insertion of the battery pack can be prevented.

According to a ninth aspect of the present invention, in the battery pack, a plurality of terminals for supplying power to the device and a surface opposite to the surface on which the plurality of terminals are provided protrude from an upper end surface of the plurality of terminals.
