DETAILED DESCRIPTION Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram showing a structure of a general vehicle instrument panel and the location of the cigar jack 11, in addition to the cigar jack is also installed in a portion of the rear seat.

Figure 2 is a perspective view of a cigar light according to the present invention, the left part of the cigarette lighter connected to the cigarette lighter attached to the form of a basic skeleton.

The method of configuring the cigar light is to control the noise voltage generated while the vehicle is running through the fuse 15 for protecting the overcurrent when the DC power is supplied through the power connection terminals 16 and 17 applied from the cigar jack. It is possible to charge the rechargeable battery 21 through the stabilization charging device 23, which is preferably secondary to the overcharge protection circuit 24 is built-in.

Referring to FIG. 3, the general principle of the overcharge protection circuit is that the current applied from the battery of the vehicle as shown in 30 of FIG. 3 is a fixed rated voltage of 12V, and the current is turned off by the OFF state of the zener diode 33. Flows through the power outlet 32. At this time, when the charging voltage of the charger connected to the power outlet 32 becomes full, when the rated voltage of the B part becomes 12V or more, the zener diode 33 is turned on and the current is changed from A to ground due to the potential difference. It will flow to prevent overcharge.

36 of FIG. 3 shows a conceptual diagram of a DC-DC charging method, in which a typical DC In power source applied from a battery of a vehicle cancels a voltage regulator and a noise wave. Through the band, it is adjusted to the voltage required by the converter. The voltage is finally filtered by a genuine DC wave in a DC control and an error amplifier, and the generated noise wave is sent back to the converter through a feedback circuit and filtered by a pure current. In the following, the LED lamp can be used as a stable DC power source. However, it is preferable to apply the stabilizing charger circuit to the cigarette light.

In addition, by adopting a winker-type blinker circuit (22) for constructing a flashing light flickering in an emergency, it is selectively used in the three-stage switch (18), the first stage has a power off (Off) function, The second stage has a flashlight function in the general first lighting method, and when the third stage of the switch is selected, the second stage can be used as a flashing light function of the second lighting method in which a blinking signal passing through the built-in blinker circuit 22 blinks.

4 shows various connection examples of the cigar light, and the LED lamp 14 is red when charging and the green when fully charged to indicate a state in which the rechargeable battery 21 is always fully charged. It is preferable to have a first display device employing a dual LED lamp to be displayed, and having a second display device with at least one LED lamp to indicate the use state of at least one multijack 13 and at least one USB port. Preferably, the multi-jack and the USB port can be used as an auxiliary power source using a mobile phone, an MP3 player, a PDA, a GPS, or the like, and may also charge the electronic product.

Referring to FIG. 11, USB differential signals D + and D- input from a USB port such as a computer are converted into USB packets in the form of digital data by a USB receiver. This USB packet is input to a Digital Phase Locked Loop (DPLL), and the DPLL removes the USB control code part from the USB packet, extracts only the data part, and inputs it to the Rx buffer. Data input to the Rx buffer is transferred to the UART interface by the Rx write signal of the Rx register. The UART interface then adds a start bit and a stop bit to the data, converts it into a UART Tx signal, which is an asynchronous signal, and moves it through a data communication port such as a mobile phone. Send by phone.

The UART Rx signal input from a data communication port such as a mobile phone is removed from the start bit and the stop bit in the UART interface. The UART interface sends a Tx read signal to the Tx register, and then the data from which the start bit and the end bit are removed is input to the Tx buffer. The data stored in the Tx buffer is transferred to the DPLL, which adds the USB control code portion to the data, packetizes it, converts the data into USB packet form, and delivers the data to the USB transceiver. The USB transceiver converts USB packets into USB differential signals D + and D- and outputs them to a USB port on a notebook computer.

FIG. 11 shows the inside of a USB cable for charging a mobile phone or the like using the USB power supply line VIN. The USB cable consists of four wires, which supply power to the device through the power line (VBUS) and ground (GND). VBUS is + 5V at the source. Data is conveyed by serial transmission of the differential signals of D + and D-.

The USB power supply line of the notebook computer or the like is connected to the power input VIN of the circuit, and the charging power line of the data communication port of the mobile phone or the like charges the built-in charger connected to the power output VOUT.

By using the characteristics of the USB port (USB) port, the USB cable for mobile phone chargers are commercially available. Since a general computer having a USB port is used only in a place where commercial power is available, the power supply to the USB port using the apparatus of the present invention is provided. It can charge the required electronics.

In other words, even if there is no cigar jack of a car or a general commercial AC power source, DC power can be input from a portable electronic device having a USB port to charge the rechargeable battery of the present invention.

The cigar light that can be used for this purpose can be deformed as shown in FIGS. 5 to 8 and 13 with its basic structure as an axis, but is not limited to a cigar jack for automobiles. The design of the cigarette lighter input terminal connected to the cigar jack is modified to take the form of the front portion (from 16 to 18), and in a manner different from the cigar plug opening method, as shown in FIG. 13, the input terminal portion of the cigar light. After pulling the slide tab 56 to the right to fix it, it may also be manufactured by a slide method that is inserted into the cigar jack 11, and also receives a general AC power (AC adapter as shown in 29 of Figure 9) connection method It is also possible to use the AC charging circuit of, while following this scheme in the rechargeable battery 21 portion in the shape as shown in Figures 5 to 8, the general It is also possible to modify the body portion that can be taken out and used after charging the rechargeable battery, in this case it may be configured as a rechargeable battery storage unit 54 that conforms to the specifications of one or more rechargeable batteries that meet the standard of the general rechargeable battery, FIG. Shows two rechargeable batteries 21 of AA standard and two rechargeable batteries 211 of AAA standard, which are charged with four rechargeable batteries.
