Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a solar battery charger that charges a rechargeable battery by generating power from a solar battery using sunlight as energy.

Structure of the conventional example and its problems As shown in FIG. 9, this type of conventional solar battery charger has solar battery parts 31 and 1 containing solar cells, and a battery pack 32 containing a rechargeable battery. When charging the rechargeable battery, the battery pack 32 is attached to the solar cell section 31 to perform charging. However, since the conventional solar battery charger uses a battery pack 32, for example, one or more rechargeable batteries are included in the battery pack 32.
There was a problem in that the output voltage was fixed depending on the number of rechargeable batteries installed.

On the other hand, depending on the device used, some are equipped with a DC jack and others are not, and therefore, conventional solar battery chargers are not suitable as chargers for a wide range of applications.

OBJECTS OF THE INVENTION In view of the above-mentioned conventional problems, it is an object of the present invention to provide a solar battery charger that can be used in a wide range of applications.

In order to achieve the object described in Structure of the Invention, the present invention provides a charging input terminal part in a battery case part which is detachably attached to a solar cell part and houses a rechargeable battery, and also provides an output terminal part. When charging the rechargeable battery, the battery case section is attached to the solar cell section, the charging input terminal section of the battery case section is brought into contact with the pair of terminal sections of the solar cell section, and the rechargeable battery is further attached to the battery case section. A removable battery cover is attached to the battery case. According to this configuration, by connecting an external device to the output terminal section of the battery case section, power can be supplied to the external device while charging the rechargeable battery. And after charging the rechargeable battery, if you remove the battery case part from the solar cell part, you can use it as a battery pick-up.Furthermore, the battery case part has a detachable battery cover that allows you to take out the rechargeable battery. The rechargeable battery can be removed from the battery case and attached to an external device for use, and since this rechargeable battery can be used with any commercially available rechargeable battery, it is easy to replace the rechargeable battery. It is possible,
Furthermore, if the battery case is constructed so that multiple rechargeable batteries can be stored, the number of rechargeable batteries can be changed according to the voltage of the equipment being used, allowing the user to freely use them. It has various revitalizing effects.

In this case, the charging input terminal portions 17 and 18 are made to protrude outward from the main body case 10.
The other end of one of the charging input terminals 1γ is directly projected outward from the main body case 10, and the other end 18/ of the other charging input terminal 18 is as shown in FIGS. 5 to 7. As shown, it protrudes outward from the main body case 10 via a rectifier 19. As shown in FIGS. 5 to 7, the board 16 is provided with an output terminal section 2o that connects directly to the outside from the charging input terminal section 17.18, and the output terminal section 2 in parentheses is
As shown in FIG. 4, the opening 21 provided in the side surface of the main body case 10 is located at the opening 21 of the main body case 10.

Also, the back surface 2 of the main body case 2 constituting the solar cell section 1
2 has two grooved guide walls 23.2 as shown in FIG.
