Description

Boost type mobile phone dc charger

The utility model relates to telephone communication, furthermore relates to the current supply arrangement of mobile portable phone.

Mobile phone is the communication tool of people's most convenient, and it can transmit information at a distance.But the battery capacity of mobile phone is limited, in case the mobile phone short of electricity just can't be used.This moment need be to battery charge.Usually the common charger for mobile phone of people is that employing is commercial power charged, can't charge in the place that does not have civil power, and mobile phone also just can not use.In recent years, people have designed some chargers without civil power, as utilize charger of solar energy etc.Yet this charger must use by day, and the sun will be arranged, and therefore, its use is subjected to condition restriction.

The purpose of this utility model is to provide a kind of use not to be subjected to weather restriction, portable direct current charger for mobile phone.

For reaching this purpose, the designer adopts the voltage oscillation pressure build-up technique to design the circuit that DC power supply is boosted, and goes out the voltage oscillation increasing apparatus according to this circuit design through research.Utilize this device, can implement charging to mobile phone with dry cell as primary power.The operation principle of this voltage oscillation increasing apparatus is as follows: export oscillating voltage by the direct current that dry cell provides at the oscillating part of circuit, and the high-frequency pulse voltage that vibrates; In the part of boosting of circuit, this high-frequency pulse voltage and electric current all are promoted to required voltage and current; The feedback fraction of circuit feeds back to oscillating circuit with the booster tension of output, and the voltage after the lifting is after exporting the electronic regulation integrated circuit to after rectification, the filtering, and the steady voltage of output 3.6～8.2V can be to cell-phone charging.

Therefore, the mobile phone dc charger that provides of the utility model comprises the lead (4) and the plug special (5) of device body (1), built-in battery case (2) and voltage oscillation increasing apparatus (3), output.

Device body (1) is suppressed on mould with plastics or plastic cement and is formed.Battery case (2) is made up of opposite, the mutual series connected battery seat of a pair of direction in an inboard of device body, and is wherein anodal with tinsel, negative pole metal spring.Voltage oscillation increasing apparatus (3) is made up of some resistance, electric capacity, transformer, diode and triode in another inboard of device body, and this circuit can adopt integrated circuit, also can be the circuit that manually is welded into.The lead (4) of output is the common metal lead; Plug (5) is the mobile phone plug special, because mobile phone model is many, therefore used socket difference will design multiple plug, selects for use for the user.

Accompanying drawing 1 is voltage oscillation booster circuit figure, and C is an electric capacity among the figure, and R is a resistance, and T is a transformer, and Q is a triode, and D is a diode, and K is a switch; Accompanying drawing 2～4 is the schematic diagram of mobile phone dc charger, and wherein Fig. 2 is a front view, and Fig. 3 is an end view, and Fig. 4 is a bottom view, 1 is the device body among each figure, and 2 is battery case, and 3 is the voltage oscillation increasing apparatus, and 4 is output lead, 5 is the mobile phone plug special, and 6 is battery case lid, and 7 is battery.

The mobile phone dc charger that uses the utility model to provide can use two joint dry cells to make power supply and give cell-phone charging easily, if No. 7 dry cells are used in design, two joint dry cells can charge twice, and mobile phone of every charging can use 20 hours.The mobile phone dc charger that uses the utility model to provide, people just can at random replenish the electric power of mobile phone in the countryside.

Boost type mobile phone dc charger of embodiment as accompanying drawing 2, its device body (1) is of a size of that 30mm is thick, 50mm is wide, 85mm is long, battery case (2) is in an inboard of device body, form by opposite, the mutual series connected battery seat of a pair of direction, wherein positive pole is made with metal spring with copper sheet, negative pole, battery (7) is contained between copper sheet positive pole and the metal spring negative pole, and battery case (2) has lid (6).Voltage oscillation increasing apparatus (3) is made up of some resistance, electric capacity, transformer, diode and triode in another inboard of device body, and this circuit is the circuit that manually is welded into.The lead (4) of output is a copper conductor; Plug (5) is the mobile phone plug special.
