Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a battery housing structure for an electronic device that uses a battery as a power source, and more particularly to a technique for cleaning a contact portion between a battery electrode and a terminal provided on the electronic device.

[0002]

2. Description of the Related Art In an electronic device that uses a battery (particularly, a secondary battery) as a power source, a non-conductive material is applied to a contact portion between a battery electrode and a terminal provided in the electronic device by repeating charging and discharging of the battery. An oxide film is formed. As a result, the electric resistance value of the contact portion between the electrode and the terminal increases, which causes a problem that the charging time of the battery is increased, the battery cannot be sufficiently charged, and the usage time of the battery is shortened.

Therefore, in order to solve the above problems, an electronic device generally has a structure in which a terminal slides about several mm when a battery is taken in and out of the electronic device, whereby an electrode slides with respect to the terminal. Then, the contact portion between the electrode and the terminal is cleaned.

However, in the conventional electronic equipment, since the battery capacity is small and the electric power consumption of the electronic equipment is large, it is necessary to replace the battery within several hours, and the frequency of battery replacement is high, which is not a problem. In electronic devices, battery capacity is increasing and power saving is progressing.Because mainstream devices are those that can be charged with the battery still installed, the frequency of battery replacement is decreasing. Therefore, the battery is mounted on an electronic device for a long time and is repeatedly charged and discharged, and the problem of an oxide film is more likely to occur.

Therefore, for example, in Japanese Unexamined Patent Publication No. 7-45263, a battery chamber having a battery terminal that contacts an electrode of a stored battery, a power switch for opening and closing an electric circuit connected through the battery, and this power switch. In a battery case equipped with a switch plate for operating the switch plate, a friction pad for rotating the battery or the battery terminal is provided in conjunction with the operation of the switch plate, and the battery terminal is provided with a relative rotation operation with the battery. Discloses that an edge portion for wiping the surface of the electrode is formed. According to this, even if the battery is left in the battery chamber for a long period of time and the non-conductive material of the oxide film is generated at the contact portion between the electrode and the battery terminal, it is oxidized by the power on / off operation. The non-conductive substance of the coating film can be wiped off, and the electrode and the edge portion of the battery terminal can be directly contacted with each other to eliminate electrical contact failure.

[0006]

However, in the above-mentioned prior art, when the battery is prismatic or the like, the battery cannot be rotated depending on the turning on / off of the power source by the switch plate. There is a point.

Further, the rotation of the battery is carried out by the frictional force between the friction pad and the surface of the battery, but there is a problem that the battery cannot be rotated due to the increase in friction between the battery and the inner surface of the battery. .

The present invention has been made in view of such a situation, and by swinging the battery in the battery housing portion in conjunction with the opening / closing operation of the opening / closing lid, the battery can be operated independently of the shape of the battery. An object of the present invention is to provide a battery housing structure of an electronic device that cleans a contact portion between an electrode and a terminal that has a small frictional force to move.

[0009]

In order to solve the above-mentioned problems, the battery storage structure for electronic equipment according to the present invention employs the following means.

A first gist of the present invention is to provide a main body, a battery storage portion provided in the main body for storing a battery, positive and negative terminals fixed to the main body and respectively contacting positive and negative electrodes of the battery, and the main body. In an electronic device including an opening / closing lid that is lockably provided, a battery storage unit includes a storage case that stores a battery and is pivotally supported by a main body, and the storage case is centered around a pivot shaft. And a biasing member that biases the storage case to be rotated in a direction.The opening / closing lid closes the opening / closing lid to press the storage case or the battery against the biasing force of the biasing member to open the storage case. The present invention relates to a battery storage structure for an electronic device, which is provided with a pressing portion that rotates in the other direction.

According to the first aspect of the present invention, by closing the opening / closing lid, the pressing portion of the opening / closing lid presses the storage case or the battery against the biasing force of the biasing member to move the storage case in the other direction. By rotating and opening the opening / closing lid, the storage case rotates in one direction according to the urging force of the urging member, thereby sliding the electrode with respect to the terminal and cleaning the contact portion between the electrode and the terminal. It

A second aspect of the present invention is to provide a main body, a battery storage portion provided in the main body for storing a battery, positive and negative terminals fixed to the main body and respectively contacting positive and negative electrodes of the battery, and the main body. In an electronic device including an opening / closing lid that can be locked and a locking member that is slidably provided on the main body and that locks the opening / closing lid on the main body so that the opening / closing lid can be opened / closed, the battery storage unit stores the battery And a biasing member for biasing the storage case to rotate in one direction around a pivot shaft. The locking member includes a locking member. An electronic device characterized by being provided with a slide pressing portion for pressing the storage case or the battery against the biasing force of the biasing member to slide the storage case in the other direction by sliding the storage case in one sliding direction. machine It relates to a battery storage structure.

According to the second aspect of the present invention, by sliding the locking member in one sliding direction, the slide pressing portion of the locking member presses the storage case or the battery against the biasing force of the biasing member. Then, the storage case is rotated in the other direction, and the locking member is slid in the other slide direction, whereby the storage case is rotated in one direction according to the urging force of the urging member, whereby the electrode is connected to the terminal. By sliding, the contact portion between the electrode and the terminal is cleaned.
