Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] This invention relates to a novel cylindrical battery that integrally combines a solar battery and a storage battery that is charged by the output of the solar battery.

[Conventional technology]

Recently, various small electric appliances such as electric shavers, liquid getter radios, and standing lights that use solar cells have come into use, but most of them have solar cells integrated into a part of the outer surface of the electric appliance, and The storage battery, which is charged using the output of the solar cells, is stored in a battery compartment located elsewhere within the electrical device.

[Problem to be solved by the invention]

However, in the above-mentioned conventional devices, it is necessary to separately provide a place for installing a solar cell and a place for storing a storage battery in one electric device, and it is also necessary to connect the solar cell and the storage battery storage part. This has caused the structure of electrical equipment to become more complex9 and the number of assembly steps to be increased.

Furthermore, in order to charge this type of electrical equipment, the electrical equipment must be placed in a place exposed to direct sunlight because the solar cell is integrated into the device. For this reason, there is a problem in that the electrical equipment, especially the plastic exterior body, is susceptible to deterioration due to ultraviolet ray irradiation and high temperature of the atmosphere during light reception.

Therefore, for example, as shown in Japanese Utility Model Application Publication No. 50-59528, a solar cell is exposed on the outer surface of a case housing a storage battery.

A device that handles a storage battery and a solar cell as a set has been proposed. However, in this case, the case for the set is set exclusively for the equipment used, so it lacks versatility to other equipment, and when using it, it is necessary to separate the equipment and the set case side each time. This was troublesome as the lead wire had to be reconnected.

An object of the present invention is to facilitate the use of solar cells in small electrical equipment by storing solar cells and storage batteries in an outer container, and to simplify the structure and assembly of the equipment.

Another object of the present invention is to enable compatibility with standard dry cell batteries such as unitary batteries.

Still another object of the present invention is to improve charging efficiency, that is, light receiving efficiency, even when charging on a desk or the like, and to prevent breakage and damage to solar cells and storage batteries.

[Means to solve the problem]

In order to achieve the above object, the present invention includes a solar cell 6 and a storage battery 5 that is charged by the output of the solar cell 6 in a cylindrical outer container 4 having negative and anode terminals 2 and 3 similar to the external shape of a standard dry battery. A flat surface 4a for preventing rolling is provided on the outer surface of the cylindrical outer container 4, and a light-receiving surface 1 of the solar cell 6 is provided at least on the side symmetrical to the flat surface 4a of the outer container 4.
A transparent surface facing 0 is formed.

[Effect]

According to the cylindrical battery having the above configuration, when this battery is used as a power source for small electric equipment, it is not necessary to separately incorporate a solar cell and a storage battery into the equipment as in the past.
It is sufficient to store this cylindrical battery in the only battery compartment in the device, and the wiring work between the solar battery and the battery compartment can be omitted, making this type of storage battery built-in type that uses solar cells as a charging source. The assembly and structure of small electrical equipment can also be simplified.

Moreover, according to this cylindrical battery, it can be directly loaded and used in small electrical equipment in place of dry batteries.

In particular, even when this cylindrical battery is charged by laying the flat surface 4a of the outer container 4 on a desk, floor, etc., it will not roll due to vibrations or the like.

The outer container 4 can be placed stably so that the light-transmitting surface facing the light-receiving surface 10 always faces upward, thereby increasing the light-receiving efficiency and preventing damage from falling due to rolling.

〔Example〕

An embodiment of the cylindrical battery according to the present invention is shown in FIGS. 1 and 2.
This will be explained based on the diagram.

In FIGS. 1 and 2, 1 is a cylindrical battery of the present invention, which has a cylindrical outer container 4 having negative and positive terminals 2 and 3.
It consists of a storage battery 5 and a solar cell 6 built into the outer container 4.

The cylindrical outer container 4 is molded from a transparent plastic material such as ABS, silicone, acrylic, acrylic styrene, or weather-resistant polycarbonate, and has a transparent surface on its entire surface. The outer surface is formed into a polyhedral cylindrical shape with many flat surfaces 4a so that it will not roll when placed.

One end opening of this cylindrical outer container 4 is sealed with an anode terminal plate 7 having an anode terminal 3 in the center, and the other end opening is sealed with a cathode terminal plate 8 having a cathode terminal 2 in the center. The anode terminal 3 and the cathode terminal 2 each have a conical projection 3a, 2a on the inside of the terminal plate 7, 8.

As the storage battery 5, a cylindrical one smaller than the outer container 4, for example, an alkaline storage battery is used.

The solar cell 6 includes a solar cell element 9 and a light-receiving surface 1 made of transparent resin.
It is formed to have an arcuate cross section covered with 0, and is attached to a part of the outer peripheral wall of the storage battery 5 along the axial direction.

Further, the anode terminals of the solar cell 6 and the storage battery 5 are connected to each other by a lead wire 12 via a backflow prevention diode 11, and the cathode terminals are connected to each other by a lead wire 13.

The solar cell 6 and the storage battery 5 integrated in this way are arranged so that each eccentric portion at the anode side end and the cathode side end of the storage battery 5 in the outer container 4 is formed by the anode protrusion 3a and the cathode protrusion 2 of the container 4.
It is stored so that it is secured and supported at point a. (Therefore, even when the outer container 4 is placed on its side with its flat surface 4a on a desk or the like as shown in FIG. 2, the light-receiving surface 10 and the flat surface 4a of the desk are point symmetrical with respect to the protrusion 3a (center of symmetry), and can be raised freely so that the light-receiving surface 10 faces upward.

The cylindrical battery 1 constructed in this way is placed in the battery compartment of various small electric devices and used as a power source for that device.In order to charge the battery, only the cylindrical battery 1 must be removed from the battery compartment. Take it out and lay it on its side on a desk exposed to sunlight.

The integrated solar cell 6 and storage battery 5 rise up using the eccentric support portions at both ends as fulcrums, with the light-receiving surface 10 facing upward, and facing the sun through the transparent surface of the outer container 4 facing the light-receiving surface 10. By the way.

The output current of the solar cell 6 passes through a backflow prevention diode 11 and charges the storage battery 5 . After charging, this battery 1 can be placed in the battery storage section and reused as a power source for the device.

Note that instead of the above embodiment, the integrated solar cell 6 and storage battery 5 are fixedly built into the outer container 4, and a weight is attached to the side symmetrical to the light-receiving surface 10 of the container 4 for charging. Even if the flat surface 4a is rolled sideways on a desk or the like, the outer container 4 itself may immediately right itself so that the light-receiving surface 10 faces upward.

In addition to making the entire outer container 4 transparent.

Only a part of the container 4 may be formed into a transparent light-transmitting surface, and the light-receiving surface 10 of the solar cell 6 may be opposed to this light-transmitting surface.

〔Effect of the invention〕

In this invention, an anode terminal 3 is provided at one end opening of the cylindrical outer container 4.
A cathode terminal 2 is provided at the opening at the other end, and a solar cell 6 and a storage battery 5 are assembled inside this container 4 to constitute one cylindrical battery 1. Therefore, this cylindrical battery 1 may also be used as a power source for various small electric devices.

It is easy to handle as it only needs to be inserted into and taken out from the only battery compartment provided in the device, and the conventional wiring work between the solar battery and the storage battery compartment can be omitted, making the solar battery the charging source. The assembly and structure of this kind of small electrical equipment, which is powered by a storage battery, can be simplified.

Further, the outer shape of the cylindrical battery 1 can be made almost the same as the standard shape of a dry cell battery established in the general JIS standard, for example, so that it can be used as a replacement for a dry cell battery in a small electric device.

Furthermore, since only the cylindrical battery 1 needs to be placed in a place exposed to direct sunlight during charging, it is possible to prevent small electric devices from deteriorating due to ultraviolet rays and extend their lifespan.

In particular, in order to make the solar cell 6 and the storage battery 5 versatile in the battery compartments of various small electric devices, and to make it easy to take them in and out, the outer container 4 has cathode and cathode terminals 2 and 2 at both ends. 3, the transparent surface of the outer container 4 facing the light-receiving surface 10 of the solar cell 6 and the flat surface 4a are arranged in a point-symmetrical relationship.

Therefore, even if it is placed on a desk or floor, it will not roll due to vibrations, etc., so the light-receiving surface 10 can always face upward, improving light-receiving efficiency, that is, charging efficiency, and preventing it from rolling. It is easy to use and prevents breakage and damage.
