Description

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

[Conventional technology]

Recently, various small electric appliances such as electric shavers, pocket 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 appliances, and storage batteries. The device is designed to be stored in a battery compartment located elsewhere within the same electrical device.

[Problem that the invention seeks to solve]

Therefore, in one electrical device, it is necessary to separately provide a place for installing a solar cell and a place for storing a storage battery, and it is also necessary to wire the solar cell and the storage battery storage part, which reduces the structure of the electric device. Complication 1 This was the cause of an increase in assembly man-hours.

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

[Means for solving problems]

In view of this fact, the present invention provides an anode terminal connected to the anode of the storage battery at one end of the cylindrical outer container containing the storage battery, and a cathode terminal connected to the cathode of the storage battery at the other end. In addition, a solar cell is arranged on the peripheral wall of the outer container along the axial direction connecting the anode terminal and the cathode terminal, and the storage battery is charged with the solar cell. The device only needs to be provided with a storage section to store it in and out, which facilitates the use of solar cells in the current small electric devices that are already in use, and simplifies the structure and assembly of the small electric devices. The present invention aims to provide a cylindrical battery that can prevent the deterioration of small electrical equipment due to ultraviolet rays, and is compatible with standard batteries established by JIS.

In particular, in this invention, the solar cell that charges the storage battery housed in the cylindrical outer container is arranged on the peripheral wall of the outer container along the axial direction of the container, so even if the outer container is cylindrical, Even if there is a solar cell, solar cells can be efficiently arranged in series, and the circumferential wall of the outer container, which has limitations, can be effectively utilized.

Moreover, by arranging the solar cells only on a specific surface of the surrounding wall, the center of gravity of the outer container can be offset from the axis of the outer container. Since the mounting surface faces upward, it can effectively receive light rays and increase charging efficiency.

〔Example〕

The details will be explained below based on the drawings. In FIGS. 1 and 2, 1 is a cylindrical battery, which includes a cylindrical outer container 4 having negative and positive terminals 2 and 3, and the outer container 4. It consists of a storage battery 5 and a solar cell 6 built in.

The outer container 4 is formed into a cylindrical shape from a transparent plastic material such as ABS, silicone, acrylic, styrene acrylic, or weather-resistant polycarbonate, and one end opening is sealed with an anode terminal plate 7 having an anode terminal 3 in the center. The opening at the other end is sealed with a cathode terminal plate 8 having a cathode terminal 2 in the center. The anode terminal 3 and cathode terminal 2 each have a conical projection 3a on the inside of the terminal plates 7, 8.
It has 2a.

As the storage battery 5, for example, a cylindrical alkaline storage battery smaller than the outer container 4 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 arc-shaped cross section and is attached to a part of the circumference of the storage battery 5 along the axial direction.

Further, the anodes 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 cathodes are connected to each other by a lead wire 13.

The solar cell 6 and the storage battery 5 are thus integrated into one block, and the eccentric parts at the anode side end and the cathode side end of the storage battery 5 are connected to the anode protrusion 3a and the cathode protrusion of the four cases in the outer container 4. By consolidating and supporting 2a,
As shown in the figure, when the outer container 4 is laid down on its side, the block can be raised freely so that the light-receiving surface 10 always faces upward.

In such cases, the above-mentioned cylindrical battery 1 is placed in the battery compartment of various small electric devices and used as a power source for that device, but in order to charge it at this time, only the cylindrical battery 1 must be removed from the battery compartment. If the block solar cell 6 and the storage battery 5 are placed on their side on a desk exposed to sunlight, the block solar cells 6 and the storage battery 5 are supported so as to be able to rise up into the outer container 4 using the eccentric support portions at both ends as fulcrums. , the light-receiving surface 10 of the solar cell 6 faces upward and faces the sun through the transparent part of the outer container 4, and the output current of the solar cell 6 passes through the backflow prevention diode 11 to charge the storage battery 5. After charging, this cylindrical battery 1 is placed in the battery storage section and can be reused as a power source for the device.

In addition, in place of the above embodiment, the solar cell 6 and the storage battery 5
is built into the outer container 4 in a fixed state, and a weight is attached to the part of the container 4 opposite to the light-receiving surface 10, so that even if the container 4 is rolled on its side during charging, the outer container 4 will immediately touch the light-receiving surface 10. You may also try to stand up in a position with the body facing upward.

In addition to making the entire outer container 4 transparent,
It is also possible to make only a part of the transparent part transparent so that the light-receiving surface 10 can be seen through this transparent part.

Furthermore, as shown in FIG. 3, the outer container 4 may be formed into a cylindrical shape with a polyhedral outer surface to prevent rolling.

〔effect〕

As explained above, in the present invention, one cylindrical battery 1 is constructed by incorporating the solar cell 6 and the storage battery 5 into the cylindrical outer container 4.

Therefore, when using this battery 1 as a power source for various small electric devices, there is no need to incorporate a solar battery into the device separately from the storage battery as in the past, and only this battery 1 can be placed in the only storage compartment. In addition, the conventional wiring work between the solar cell and the storage battery compartment can be omitted, which simplifies the assembly and structure of this type of small electrical equipment with a built-in storage battery that uses solar cells as a charging source. be able to. Moreover, since only the cylindrical battery 1 needs to be placed in a place exposed to direct sunlight during charging, it is possible to prevent the small electric device from deteriorating due to ultraviolet rays and extend its lifespan.

In particular, since the outer container 4 is formed into a cylindrical shape and receives light from its circumferential surface, the light receiving area can be made as wide as possible. Moreover, the external shape of the cylindrical battery 1 can be made almost the same as the standard shape of dry batteries established in the general JIs standard, for example, so that it can be used for small electric devices.
It can also be used in place of dry batteries.
