Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable battery charger for a digital camera, and a built-in battery for extending the driving time of the built-in battery, which is the biggest weakness of the digital camera. If the battery is worn or lost, you can charge it using this rechargeable charger alone, or supply power from the AC input terminal even with a dry battery type digital camera,
The present invention relates to a portable charger for a digital camera that can easily supply power anywhere via a DC adapter. 2. Description of the Related Art In recent years, the spread of digital cameras and the diversification of functions have been remarkable. In the present digital cameras, functions for listening to music, functions for shooting moving images, and functions for referencing images have been added. LCDs have been increased in size and quality, and with the recent decline in memory prices, large-capacity recording and storage media have become prices that consumers can easily purchase. It has become possible and has been used for a relatively long time. [0003] However, at this time, since a rechargeable battery or a dry battery built in a digital camera cannot secure a sufficient driving time, at present, the provided functions cannot be sufficiently used in daily life. Against this background, some devices have already emerged in the market to make up for it. However, an AC adapter as a device having a charging function and power supply is poor in handling and portability, and there is almost no DC adapter provided by a digital camera manufacturer. Is the current situation. Therefore, taking into consideration the actual user as the highest priority, a portable charger that is excellent in portability, easy to handle, does not generate waste batteries, and can be used for expiration charging or recharging in order to extend the use time has been developed. Aspired. SUMMARY OF THE INVENTION Accordingly, the present invention is to solve the conventional problems and to achieve the object of the invention, and the present invention provides a portable charger for a digital camera. , Charging from removable and replaceable rechargeable batteries,
Using a built-in AC adapter function to charge and store electricity from a household power supply using a foldable outlet plug, and using a built-in DC adapter function to charge and store electricity from a car cigarette lighter hole using a car cigarette lighter plug and transform The control circuit on the control board controls, removes and replaces the chargeable rechargeable battery, and supplies power to the built-in rechargeable battery of the digital camera connected to the digital camera connection plug or the AC input terminal to charge and It is a three-system integrated type that can extend the use time. Embodiments of the present invention are as follows. That is, in a portable charger for a digital camera, a rechargeable battery such as a lithium-ion rechargeable battery that can be recharged and has no memory effect is used, and the rechargeable battery connected to the present charger uses the built-in AC adapter function to provide AC power. The power is temporarily stored by the supply of external power such as a DC power supply using a power supply or a DC adapter function, and the power is supplied to a built-in rechargeable battery of the digital camera or the main body of the digital camera to replenish the power or perform an expiration charge. The control circuit, voltage monitoring circuit, charge management circuit, AC / DC transformer circuit, plug for outlet,
It is conceivable that the product with the integrated DC power input jack can be used by connecting it to the digital camera by itself.However, by attaching the digital camera fixing bolt to the tripod screw hole of the digital camera body, Because it can be integrated, it is excellent in portability and convenience, and it can be integrated with various existing camera peripherals such as a tripod and external flash in the tripod mounting screw hole at the bottom of the main unit, compatibility and environment Issues are fully considered. If the voltage and the power supply are compatible by using a large-capacity lithium-ion rechargeable battery or the like with a built-in charger, and the voltage and power supply are compatible, an externally mounted flash, PDA It can be widely used as an external power source for portable terminals such as electronic notebooks, video cameras, mobile phones, etc.In addition, since a replaceable rechargeable battery is used, it is possible to replace a rechargeable battery that has reached the end of its life or to use a larger capacity. It is also possible to replace the battery with one that you own. An embodiment of the present invention will be described with reference to the drawings. 1
Is a charger body, 2 is a rechargeable battery using lithium ion, etc.,
3 is a connection terminal between the rechargeable battery and the main body 1, 4 is a bolt for fixing a digital camera, 5 is a control board, 6 is a foldable outlet plug, 7 is a DC output jack, 8 is a DC 12 V input jack, 9 is an indicator, Reference numeral 10 denotes a screw fastening portion for fixing a digital camera, 11 denotes a screw hole for attaching a tripod, etc., 12
Is a DC 12V input plug provided at one end of a cigarette lighter cable, 13 is a cigarette lighter plug, 14 is a DC provided at one end of a connection cable of a digital camera or a mobile phone.
An input plug, 15 is a digital camera connection plug provided at the other end of the digital camera, and 16 is a mobile phone connection plug provided at the other end of the mobile phone connection cable. Specific use examples Specific use examples of the present invention are as follows. Using a built-in AC adapter, input from an electrical outlet using the foldable outlet plug 6, or use a DC adapter to connect the cigarette lighter plug 13 from the cigarette lighter hole through the DC12V input plug 12 to DC
Power is supplied through the 12V input jack 8. The power supply and charging are managed by the control board 5 to temporarily charge the detachable and replaceable rechargeable battery 2 connected to the connection terminal 3 between the rechargeable battery and the main body. Using the stored power supply, the DC output jack 7 and the DC output plug 14 are connected, and power is supplied to the built-in rechargeable battery of the digital camera device connected to the digital camera connection plug 15 and the digital camera body. The function of supplying, charging or supplying power is the main use. In addition, a built-in rechargeable battery of a digital camera or a digital camera connected to a plug 15 for connecting a digital camera while charging a rechargeable battery 2 such as a removable and replaceable lithium ion connected to the portable charger. There are two ways to use it to supply power to the main unit. The power stored in the detachable and replaceable rechargeable battery 2 such as lithium ion connected to the portable charger is not only a digital camera but also an output plug 14.
Is connected to the DC output jack 7 to extend the use time of a digital camera or an electronic organizer having the same connector shape, to serve as an external power source for emergency use, and to provide a method of supplying power. According to the present invention having the above configuration, the following effects can be obtained. That is, the rechargeable battery, the control circuit, and the connectors are all compactly housed in the same housing, and excellent portability is obtained. Since a rechargeable lithium-ion battery or the like with little deterioration due to additional charging or a memory effect is used as a built-in rechargeable battery, a dry battery or the like is not wasted and economical, and handling is automatically performed by a control board. This eliminates the need to charge the battery after it has been used up like a nickel-cadmium battery or a nickel-metal hydride battery, and does not burden the user. The present rechargeable battery is also used for supplying power to the digital camera body and charging the built-in battery of the digital camera.
It can be used safely without breaking the digital camera body by the monitoring circuit of AC power supply and DC power supply. In addition to the use of domestically produced digital cameras and the like, the built-in transformer circuit can handle power from an electrical outlet in most countries, and can change the DC output and the shape of the plug for connecting the digital camera. The change has the effect of being compatible with many digital cameras and peripheral devices.
