Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a mobile phone device including a portable and convenient mobile phone and a charger for charging the mobile phone, and more particularly to improve the safety of the mobile phone by protecting charging electrodes in the mobile phone. The present invention relates to a mobile phone device that can be used.
[0002]
[Prior art]
Conventionally, many mobile phones (including PHS) are provided with a charging electrode terminal exposed on the bottom thereof, and when charging, the lower portion of the mobile phone is used as a dedicated battery charger with a bottomed container. The charging electrode terminal of the cellular phone protrudes from the bottom surface of the charger and abuts on the charging electrode terminal that can be moved up and down by a spring or the like, so that a charging current flows.
[0003]
[Problems to be solved by the invention]
However, the above-described conventional mobile phone has been miniaturized and is often stored in a pocket or a bag. When a conductive metal, such as a necklace or chain, is placed in the pocket or bag, and the mobile phone is put together there, the conductive metal is exposed to the charging electrode terminal exposed on the mobile phone. When touched, there is a possibility that the charging electrode terminal is conductive, that is, the secondary battery inside the mobile phone is short-circuited. Many secondary batteries used in mobile phones are large-capacity lithium-ion secondary batteries, etc., and if this is short-circuited, not only will there be significant heat generation or damage to the mobile phone, but it will also damage the human body. There is a risk of incurring the danger of.
[0004]
Therefore, the mobile phone device of the present invention aims to further improve the safety of the mobile phone by reliably protecting the charging electrode in the mobile phone.
[0005]
[Means for Solving the Problems]
In order to achieve the above-described object, a mobile phone device of the present invention includes a mobile phone having a built-in battery and a charging electrode terminal used for charging the battery, and the charging electrode terminal at the time of charging. A mobile phone device comprising a charger that contacts the mobile phone and charges a battery of the mobile phone, wherein the outer case of the mobile phone is rotatably supported by the outer case and attached to the rotary shaft. The urging member forms an openable / closable lid that is maintained in a closed state except during charging, an engagement recess is formed in the lid, and the lid has an inner periphery of the lid. An engaging convex portion that engages with the engaging concave portion is formed so as to project, and the engaging convex portion of the charger is engaged with the engaging concave portion of the lid portion of the mobile phone that is inserted during charging. open by pushing up rotating capped, only the lid is opened during charging Is characterized in that the charging electrode terminals of the cellular phone exposed contacts energizing the charging electrode terminals of the battery charger by.
[0006]
Further, the urging member is a spring member attached to the rotating shaft portion of the lid portion.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
1 to 5 show a mobile phone and a charger constituting the mobile phone device of the present invention, in which 1 is a mobile phone and 2 is a charging electrode terminal 3 disposed at the lower part of an exterior case of the mobile phone 1. 4 is a charger for charging the mobile phone 1, and 5 is a charging electrode terminal protruding from the bottom surface of the charger 4, which can be moved up and down by an internal spring or the like.
[0008]
FIG. 3 is a cross-sectional view showing a state before the cellular phone 1 is engaged with the charger 4. As shown in FIG. 6, the lid portion 2 is provided with a spring member 6 on at least one of the rotation shaft portions 2 a at the left and right ends. It is provided so that it can be opened and closed by rotating. Then, the charging electrode terminal 3 exposed in the conventional mobile phone is hidden by the lid 2 being covered.
[0009]
As shown in FIGS. 1 and 6, two engaging recesses 7 are formed in the lid portion 2 of the mobile phone 1, and the engaging recess 7 is formed on the inner periphery of the charger 4 as shown in FIG. 2. Two engaging convex portions 8 that are engaged with each other protrude.
[0010]
Then, as shown in FIG. 4, when the mobile phone 1 is inserted into the charger 4, the engaging convex portion 8 of the charger 4 is engaged with the engaging concave portion 7 of the lid portion 2, and the lid portion 2. Push up and rotate. When the cellular phone 1 is further lowered, as shown in FIG. 5, the lid 2 further rotates upward to expose the charging electrode terminal 3, and the charging electrode terminal 3 is located below the charger 4. In contact with the charging electrode terminal 5 to be in an electrically conductive state.
[0011]
When the charging is completed and the mobile phone 1 is taken out from the charger 4, the engagement recess 7 of the lid 2 is not urged by the engagement protrusion 8 of the charger 4, and the biasing force of the spring member 6 is removed. As a result, the lid 2 is rotated downward again to automatically cover the charging electrode terminal 3.
[0012]
In the above-described embodiment, the lid portion is described as being configured to rotate using a spring member. However, the present invention is not limited to this, and when the mobile phone is set in the charger, the charging electrode terminal is Any cover may be used as long as the charging electrode terminal is automatically closed when the mobile phone is taken out from the charger after being automatically exposed and charged.
[0013]
【The invention's effect】
Therefore, according to the mobile phone device of the present invention, a mobile phone having a built-in battery and provided with a charging electrode terminal used for charging the battery, and the charging electrode terminal at the time of charging are brought into contact with the mobile phone device. In a mobile phone device comprising a charger for charging a battery of a telephone, an openable / closable lid is formed on an exterior case of the mobile phone, and the charger is formed on the lid of the mobile phone during charging. An engaging portion that engages with the engaging portion and opens the lid portion is provided, and the charging electrode terminal of the mobile phone is exposed when the lid portion is opened only during charging to expose the charging electrode terminal of the charger. By energizing the battery, it is possible to automatically expose the charging electrode terminal of the mobile phone during charging without making the user aware of it, and to automatically cover the charging electrode terminal when carrying it, As a result, after charging However, the charging electrode terminal of the mobile phone will not be exposed, so it will not be possible to accidentally touch the conductive metal in the pocket, etc., and the battery inside the mobile phone will be short-circuited. Sometimes a smooth and suitable state of charge can be obtained, which greatly contributes to the improvement of safety especially when carrying a mobile phone.
[0014]
In addition, the openable / closable lid of the mobile phone is supported by the outer casing of the mobile phone so as to be rotatable, and is kept closed by the urging member except during charging. The lid of the mobile phone can be automatically opened and charged only when charging, and the risk of short-circuiting when the lid is covered with the charging electrode terminal of the mobile phone is ensured except when charging. It can be prevented.
[0015]
In addition, the engaging portion of the lid portion of the mobile phone is a recess formed in the lid portion, and the engaging portion of the charger protrudes from the inner periphery of the charger and is inserted when charging. By engaging with the recessed part and pushing up the cover part to rotate it into a convex part that opens, the mobile phone can be easily and reliably opened by simply inserting the mobile phone into the charger. can do.
