Description

  The present invention relates to a charger for a portable device that includes a solar cell panel and that can convert solar energy into electric energy, store it in a built-in battery, and charge a battery such as a mobile phone.

  For example, a mobile phone as a mobile device includes a battery inside the main body, and when charging is necessary, the battery is charged using a dedicated AC charger. However, since the dedicated AC charger is bulky, it is troublesome to carry the AC charger when traveling or traveling.

  Also, chargers with a built-in dry battery are commercially available, but the dry battery itself is heavy and difficult to carry. Recently, a charger for a mobile phone equipped with a solar cell panel is known (for example, , See Patent Document 1).

The mobile phone charger shown in Patent Document 1 includes a battery inside a rectangular parallelepiped body, a solar cell panel mounted on the surface of the body, and a charging connector provided at the end of the body. And if a solar cell panel receives sunlight energy, the energy will be converted into electric energy, and it will be stored in the battery inside a body. Therefore, the battery of the mobile phone can be charged by connecting the charging connector to the charging terminal of the mobile phone.

A plurality of electronic components 26 are mounted on the upper surface of the electronic component substrate unit 25, that is, on the side opposite to the surface in contact with the battery 23. An LED 27 serving as a display element for displaying the state of charge is fixed to the upper surface of one side of the electronic component board unit 25. The LED 27 can confirm the upper case 13 from the side.

  The upper case 13 has the upper surface portion 17 fitted with the solar cell panel 20 with the light receiving surface 20a facing upward. This solar cell panel 20 is electrically connected to the electronic component substrate unit 25 and the battery 23 via lead wires (not shown), and when the light receiving surface 20a receives solar energy, the energy is converted into electric energy, The battery 23 is charged with electricity.

  The bottom surface portion 14 on the front side of the lower case 12 is provided with a charging connector housing portion 28 formed of a recessed portion having openings 28a and 28b on the lower surface side and the front portion side. A pivot 29 that protrudes into the charging connector housing 28 is provided in a part of the lower case 12, and a charging connector 30 that can be connected to a charging terminal of a mobile phone (not shown) is supported on the pivot 29. As shown in FIG. The charging connector 30 has a connector case 31 having an arc surface 31 a centering on a pivot 29, and a connector body 32 electrically connected to the electronic component board unit 25 is provided inside the connector case 31. .

  Furthermore, the lower case 12 and the connector case 31 of the charging connector 30 are provided with sliding surfaces 33 a and 33 b that slide when the charging connector 30 rotates. One of the sliding surfaces 33a and 33b is provided with an engaging convex portion 34, and the other 33b is provided with an engaging concave portion 35. The engaging convex portion 34 and the engaging concave portion 35 are engaged during the rotation of the charging connector 30, for example, at a position of 80 to 110 °, so that the charging connector 30 can be locked. The engaging recesses 35 are not limited to one each, and a plurality of engaging recesses 35 may be provided so that the charging connector 30 can be locked by engaging with the engaging protrusions 34 at an arbitrary position.

  Therefore, when the charging connector 30 is housed in the charging connector housing portion 28, the opening 28b is closed by the connector case 31 and the connector main body 32 as shown in FIG. As shown in FIG. 2, the state where the connector 28 moves and protrudes from the charging connector housing 28 is such that the opening 28 a is blocked by the connector case 31, and a part of the connector case 31 and the connector body 32 protrude from the opening 28 b. It becomes a state. Further, at this time, since the connector case 31 protrudes (t) from the end surface of the case body 11 of the charger, the case body 11 and the mobile phone do not interfere when charging by connecting to the mobile phone.

The AC charging coupling portion 36 is protected by an AC cap 37 that can be opened and closed. The AC charging connector is connected to the AC charging coupling unit 36 via a cord. The AC charging connector is connected to the AC charging coupling unit 36, and the AC charging connector is connected to an AC outlet, whereby the battery 23 is connected to the battery 23 by an AC power source. It can also be charged.

  Further, an air layer 38 is provided between the upper surface of the electronic component substrate unit 25 provided in the lower case 12 and the lower surface of the solar cell panel 20 provided on the upper surface of the upper case 13. The solar cell panel 20 rises in temperature due to solar energy, but the generated heat is prevented from being transmitted to the battery 23 and the electronic component board unit 25 by the air layer 38, and the battery 23 and the electronic component board unit 25 are adversely affected by heat. Is preventing.

  Note that a strap hole 39 is provided at a corner at the end of the case body 11 so that a ball chain type strap or a strap with a cranikan ring can be inserted and suspended from a mobile phone.

  The mobile phone charger thus configured fits the fitting peripheral wall 15 of the lower case 12 and the fitting peripheral wall 18 of the upper case 13. In this state, when the fixing screw 22 is inserted from the through hole 14 a side of the lower case 12 and screwed into the screw hole of the upper case 13, the lower case 12 and the upper case 13 are fixed.

  Further, the lower case 12 is provided with a charging connector housing portion 28 formed of a recessed portion, and a charging connector 30 that is rotatable about a pivot 29 is provided inside the charging connector housing portion 28. Therefore, the charging connector 30 can be rotated within a range of 180 ° with the pivot 29 as a fulcrum. When not in use, the charging connector 30 can be stored in the charging connector storage portion 28. When in use, the charging connector 30 can be stored. 30 can be rotated to protrude from the charging connector housing 28.

  In addition, the lower case 12 and the connector case 31 of the charging connector 30 are provided with an engaging convex portion 34 and an engaging concave portion 35. The engaging convex portion 34 and the engaging concave portion 35 are engaged during the rotation of the charging connector 30, for example, at a position of 80 to 110 °, so that the charging connector 30 can be locked. Therefore, as shown in FIG. 5A, by locking the charging connector 30 in the middle of rotation, the charging connector 30 becomes a support member, and the charger can be supported in an inverted state. Moreover, as shown in FIG.5 (b), by locking the charging connector 30 in the middle of rotation, the charging connector 30 becomes a support member and can support a charger in an inclined state.

  Thus, solar charging can be efficiently performed by directing the light receiving surface 20a of the solar cell panel 20 in the incident direction of the sunlight depending on the installation state of the charger.

  In the above embodiment, the mobile phone has been described, but it can also be used to charge a mobile device such as a personal computer.
