Description
본 발명은 솔라셀이 부착된 휴대용 전자기기에 관한 것으로 더 상세히는 MP3, 휴대용 텔레비젼, 휴대용 카세트플레이어등 각종 휴대용 전자기기에 솔라셀이 부착된 전자기기에 관한 것이다.The present invention relates to a portable electronic device with a solar cell, and more particularly, to an electronic device with a solar cell attached to various portable electronic devices such as MP3, portable TV, portable cassette player, and the like.
주지하는 바와 같이 되는 휴대용 전자기기는 주머니에 휴대하거나 목걸이로 목에 걸고 다니는 것이므로 그 무게가 특히 가벼워야 하고 크기가 작아야 하는 것이다. 반면에 휴대용 전자기기의 배터리의 소형화, 경량화 기술은 니켈카드늄(Ni-Cd)배터리에서 니켈수소(Ni-H)배터리 그리고 근래에는 리튬-이온(Li-ion)배터리까지 진보되어 왔으나, 여전히 배터리의 기술 수준은 휴대용 전자기기의 본체에 내장되는 반도체 기술 진보 속도에 비하여 월등히 낙후되어 있는 실정이어서 휴대용 전자기기 본체보다 배터리의 무게가 월등히 더 무겁고 부피가 큰 문제점이 있는 것이다. 그러므로 솔라셀을 사용하여 무겁고 부피가 큰 배터리를 사용할 필요가 없는 간편한 휴대용 전자기기도 보급되어 활용되고 있다. 반면에 이러한 솔라셀은 소형화된 휴대용 전자기기의 표면 일부분을 할당하여 설치되고 사용되고 있는 것이므로 그 발전량이 매우 작아 손목시계나 전자계산기등 전력소모가 작은 일부 제한된 용도에서만 활용되고 있는 것이다.As is well known, portable electronic devices are carried in a pocket or worn around a neck with a necklace, so they must be particularly light in weight and small in size. On the other hand, the miniaturization and lightening technology of batteries in portable electronic devices have been advanced from nickel-cadmium (Ni-Cd) batteries to nickel-hydrogen (Ni-H) batteries and recently lithium-ion (Li-ion) batteries. The technology level is far behind the progress of semiconductor technology advancement in the main body of the portable electronic device, so the weight of the battery is much heavier and bulkier than the main body of the portable electronic device. Therefore, portable electronic devices that use solar cells and do not have to use heavy and bulky batteries are also being used. On the other hand, since these solar cells are installed and used by allocating a portion of the surface of a miniaturized portable electronic device, the amount of power generation is very small and is used only in some limited applications such as watches and electronic calculators.
그러므로 비교적 전력소모가 많은 휴대용 텔레비젼이나 MP3, 카세트플레이어등에는 여전히 부피가 크고 무거운 배터리를 여전히 사용하여야 하는 문제점이 있다.Therefore, portable TV, MP3, cassette player, etc., which have relatively high power consumption, still have to use a bulky and heavy battery.
상술한 종래의 문제점을 감안하여 본 발명의 목적은 휴대용 전자기기에 부착되는 솔라셀의 표면적을 최대로 넓게 함으로써 전력소모가 많은 휴대용 전자기기에 널리 적용가능한 솔라셀이 부착된 휴대용 전자기기를 제공하는 것이다.SUMMARY OF THE INVENTION In view of the above-mentioned problems, an object of the present invention is to provide a portable electronic device with a solar cell, which is widely applicable to portable electronic devices with high power consumption by maximizing the surface area of the solar cell attached to the portable electronic device. will be.

이러한 본 발명을 첨부된 도면을 참조하여 상세히 설명하면 다음과 같다.This invention will be described in detail with reference to the accompanying drawings as follows.
본 발명은 기본적으로 조작버튼과 표시창 또는 화면등을 구비하여서 된 공지의 본체의 일면 전체에 하나 이상의 솔라셀을 설치하여서 된 것이다.The present invention is basically provided by installing one or more solar cells on the entire surface of a known body provided with an operation button and a display window or a screen.
이하 첨부된 도면을 참조하여 본 발명의 바람직한 실시예를 설명한다. 도1에서 볼수 있는 바와 같이 본 발명은 조작버튼(1)과 표시창(2)등을 구비하여서 된 공지의 휴대용 전자기기 본체(3)에 있어서, 그 일면과 동일한 크기의 솔라셀 패널(4)을 하나 이상 설치하여서 된 것이다.Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

이와 같은 본 발명은 휴대용 전자기기의 전면에 솔라셀 패널(4)을 힌지(5)로 고정하며 표면이 노출되도록 하여 사용하지 않은 시간 동안 휴대용 전자기기를 책상이나 차량의 운행중 대쉬보드위에 놓아두거나 휴대하면 노출된 표면의 솔라셀(9) 표면으로 빛에 의한 발전이 이루어지고 이는 내장된 배터를 충전시킴으로써 휴대용 전자기기의 사용시 전원으로 활용되는 것이다.In the present invention, the solar panel 4 is fixed to the front of the portable electronic device with a hinge 5, and the surface is exposed so that the portable electronic device is placed on the dashboard or the portable vehicle while the vehicle is not used for a period of time when it is not used. When the solar cell (9) surface of the exposed surface is generated by the light is generated, which is used as a power source when using a portable electronic device by charging the built-in batter.
이와 같이 본 발명에서는 휴대용 전자기기의 일면과 동일한 크기의 솔라셀 패널(4)에 의하여 휴대용 전자기기의 배터리 충전에 필요한 충분한 정도의 전력을 생산할수 있게 되는 것이다.As described above, in the present invention, the solar panel 4 having the same size as one surface of the portable electronic device is capable of producing a sufficient amount of electric power necessary for charging the battery of the portable electronic device.
또한, 본 발명에서 사용 가능한 솔라셀(9)은 실리콘(Si)·갈륨비소(GaAs)·In addition, the solar cell 9 usable in the present invention is made of silicon (Si) gallium arsenide (GaAs).
황화카드뮴(CdS)·인듐인(InP) 또는 이것들을 복합한 것등 다양한 종류의 것을 사용할수 있으며, 실용상 실리콘 태양전지를 사용하는 것이 경제적이다. 이러한실리콘 솔라셀 소자(素子) 1개 당의 개방단광전압(開放端光電壓)은 약 0.55 V이므로 이를 직렬 접속하거나 승압회로와 함께 사용하여 휴대용 전자기기의 전원전압인 1.5V 내지 6V수준으로 향상시켜야 함은 물론이다.Various types such as cadmium sulfide (CdS), indium phosphorus (InP), or a combination thereof can be used, and it is economical to use silicon solar cells for practical use. Since the open short-circuit voltage per silicon solar cell device is about 0.55 V, it must be connected in series or used with a booster circuit to increase the power supply voltage of portable electronic devices to the level of 1.5 V to 6 V. Of course.
이러한 실시예에서는 힌지(5)로 솔라셀 패널(4)이 연결되어 있으므로 이를 열어 노출된 전면의 버튼(1)등을 조작하여 사용하여야 함은 물론이다.In such an embodiment, since the solar panel 4 is connected to the hinge 5, the solar panel 4 is opened and used to operate the exposed button 1 on the front.

그리고 본 발명에서는 도1로 보인 바와 같이 솔라셀패널(4) 바깥에 솔라셀(9)이 설치된 형태의 것에 있어서, 도3으로 보인 바와 같이 본체(3)와 개폐되는 솔라셀패널(4)간에 발전 전력 전송을 위한 고정접점(6) 및 이동접점(7)을 설치할수도 있고, 도4로 보인 바와 같이 플렉시블와이어(8)를 이용할수도 있음은 물론이다.In the present invention, as shown in FIG. 1, the solar cell 9 is installed outside the solar cell panel 4, and as shown in FIG. 3, between the main body 3 and the solar cell panel 4 that is opened and closed. Of course, the fixed contact 6 and the mobile contact 7 for generating electric power transmission may be provided, and the flexible wire 8 may be used as shown in FIG.
아울러 본 발명에서는 도5로 보인 바와 같이 솔라셀(9)의 보호를 위하여 솔라셀(9)이 솔라셀패널(4) 외측이 아닌 내측에 설치되도록 할수도 있는 것이며, 이경우에는 외부의 날카로운 물건이나 충격에 대하여 솔라셀(9)이 보다 안전하게 보호될수 있는 잇점이 있음은 물론이다.In addition, in the present invention, as shown in FIG. 5, for the protection of the solar cell 9, the solar cell 9 may be installed on the inner side of the solar cell panel 4 instead of the outer side. Of course, there is an advantage that the solar cell 9 can be more safely protected against impact.
아울러 이러한 형태에서는 솔라셀(9)에 의한 발전이 이루어지도록 하기 위하여 필히 솔라셀 패널(4)을 열어 두어야 하는 것이며, 그러므로 휴대용 전자기기를 도5로 보인 바와 같이 세워 두는 것이 바람직하다.In addition, in this form, it is necessary to keep the solar cell panel 4 open so that power generation by the solar cell 9 can be achieved. Therefore, it is preferable to put the portable electronic device as shown in FIG.
