Abstract

The utility model discloses a small manual charger, which comprises a casing, a spring handle and a charging circuit, wherein the interior of the casing is provided with a micro-generator (7) and a sector rack (1). The drive force is transmitted via a small gear (2) and a large gear (3) to a small gear (4) on the input shaft of the generator, thereby driving the generator to rotate for power generation. The utility model has the advantages of simple structure, small size, light weight as well as excellent portability and can conveniently charge a small DC electrical appliance such as a cell phone, a CD player, a radio recorder or an MP3 player etc. in case of no power supply.

Description

The manual small charger

Technical field

The utility model belongs to charging device, is particularly useful for mobile phone, radio-cassette player, CD player, MP ₃Immediately charge etc. small-sized DC electric appliance manual.

Background technology

Existing charger, especially battery charger for mobile phone mostly are the chargers of making power supply with alternating current, when the user goes out or then can't be to battery charge in the place that does not have power supply, cause electrical equipment such as mobile phone to use, and cause inconvenience.

Summary of the invention

The purpose of this utility model provides a kind of under the situation of AC-less power, and the manual small charger that can charge at any time is to overcome the deficiencies in the prior art.

The utility model is achieved by the following technical solution: a kind of manual small charger, it comprises shell, handle and charging circuit that one end is hinged and can suppresses on shell, it is characterized in that having in the enclosure microgenerator, pinion and gear wheel are linked as holistic duplicate gear, the sector rack that is meshed with pinion, one end of sector rack is fixed on the hand end of handle, gear wheel is meshed with pinion on being fixed on generator power shaft front end, the ratchet and pawl that prevents the generator counter-rotating is housed on pinion, and the power shaft and the output shaft of generator all are contained on the housing.

Its good effect is: owing to adopted such scheme, can make the utlity model has simple in structure, volume is little, easy to carry, lightweight advantage.Both can be used for the manual powered of battery of mobile phone, also can be used for other as CD player, radio-cassette player, MP ₃Small-sized DC electrical equipment such as machine manual powered.

Description of drawings

Below in conjunction with drawings and Examples the utility model is described in further detail.

Fig. 1 is that master of the present utility model looks sectional structure chart;

Fig. 2 is the A-A cutaway view of Fig. 1;

Fig. 3 is the handle state diagram of upspringing;

Fig. 4 is charging circuit figure.

Among the figure: 1. sector rack, 2. pinion, 3. gear wheel, 4. pinion, 5. ratchet, 6. ratchet, 7. generator, 8. shell, 9. handle.

Embodiment

With reference to Fig. 1, Fig. 2 and Fig. 3, the utility model shell (8) is an egg type, one handle that can suppress (9) is arranged in the above, the one end strand of handle (9) is connected on the shell (8), the other end is connected and fixed sector rack (1), and a microgenerator (7) is arranged in shell (8), and pinion (2) is linked as holistic duplicate gear with gear wheel (3), sector rack (1) and pinion (2) engagement, gear wheel (3) is meshed with the pinion that is fixed on generator power shaft front end (4); For preventing the counter-rotating of generator, the ratchet and pawl arrangement that ratchet (5) and ratchet (6) are formed is housed on the pinion (4) of generator (7); The power shaft of generator and output shaft all are contained on the housing (8).

With reference to Fig. 4, in the present embodiment, charging circuit is three-phase bridge rectification, filter circuit and capacitor C 1 charging, the discharge circuit that 6 diodes are formed.Also can adopt other charging circuit.

The tool course of work is as follows: lift charger handle (9) and suppress handle (9) repeatedly, make it to move up and down, the sector rack (1) that is fixed on the handle drives pinion (2) rotation, the gear wheel (3) coaxial with pinion (2) rotates, pinion (4) on gear wheel (3) the pushing generator power shaft rotates, thereby pushing generator (7) rotary electrification produces voltage at the coil two ends.Voltage charges the battery after charging circuit rectification, filtering.

Claims
