Abstract
The utility model relates to a novel large power hand-operated three-phase generator which includes a handle, a handle fixed plate, a driven gear, a press mounting gear, and a generator box. The inside of the box is provided with a permanent magnet, a coil, a base plate, a PCB, a housing, a shaft, a bearing, a pad, and a plurality of screws. The handle is arranged on the press mounting gear via the handle fixed plate. The press mounting gear is arranged on the housing via the handle fixed plate. The diameter of the driven gear is substantially smaller than the diameter of the press mounting gear, and the driven gear is fixed on a middle position of the housing via the shaft. The housing is fixed with the bottom plate via the screws to form the box of the generator. The PCB is arranged on the bottom plate. The shaft is arranged on the bearing. The bearing is fixed on the bottom plate via the screws. The bottom of the bearing is provided with the pad to prevent the bottom plate from directly generating friction with the shaft, so the service lifetime can be prolonged. The permanent magnet is arranged on the periphery of an inner wall of the housing while surrounding the coil. The coil is arranged in the box of the generator via the screws while surrounds the bearing.
Description
Technical field
The utility model relates to a kind of generator, refers more particularly to the hand threephase generator of novel high-power that a kind of product such as broadcast receiver, flashlight that can be used for storage battery is done charge power supply.
Background technology
The existing products such as broadcast receiver, flashlight that are used on the market with storage battery are made the hand generator of charge power supply, and this series products power output is little, and the about P=2～10W of its power (rotating speed 3000rpm) has characteristics such as volume is big, thickness is big.And its scope of application is more single than religion, generally is cannot make DC power supply to use.
The utility model content
The purpose of the utility model is to provide a kind of novel high-power hand threephase generator.It has the big characteristics of power to the hand threephase generator of this novel high-power with respect to existing hand generator, its power output P＞20W (rotating speed 3000rpm).The utility model not only has high-power characteristics but also its volume is little, thin thickness, its three-phase power output are directly proportional with rotor speed, alternating voltage, the electric current of this generator output
After over commutation and filtering, also can make DC power supply and use.
The hand threephase generator of a kind of novel high-power, it comprises that a handgrip, a handgrip fixed head, a driven gear, press-fit gear, a generator casing.Draw together in this casing and comprise a permanent magnet, a coil, a base plate, a PCB circuit board, a shell, one, a bearing, a pad, some screws.This handgrip is installed in through the handgrip fixed head and press-fits on the gear, and this press-fits gear and also is installed on the shell through the handgrip fixed head.The diameter of this driven gear will be much smaller than the diameter that press-fits gear, and this driven gear is through a middle part that is fixed on shell, this driven gear with press-fit gear and remain on same plane and intermesh.This shell is through some screws and the fixing casing that forms generator of base plate.This PCB circuit board is installed on the base plate.This axle is installed on the bearing, and this bearing is fixed on the base plate through some screws, and in the bottom of this bearing one pad is installed, and avoids base plate and axle directly to produce friction, to increase the service life.This permanent magnet around coil be installed in outer casing inner wall around, this coil is installed in the casing of generator through some screws around bearing.
Its operation principle is following: when hand handgrip; The gear driven driven gear that press-fits that is installed together with handgrip rotates; Because this press-fits the diameter of the diameter of gear much larger than driven gear; Press-fit gear rotate a circle quite and driven gear rotate some circles; Under the slow-speed of revolution, can drive driven gear and rotate faster so it press-fits gear, this driven gear rotates and can drive axle and bearing and rotate and also can drive coil simultaneously and rotate generating, and this electric energy do charging can for through the output of PCB circuit board the products such as broadcast receiver, flashlight of band storage battery.

Embodiment
The hand threephase generator of a kind of novel high-power, it comprises that a handgrip (1), a handgrip fixed head (2), a driven gear (3), press-fit gear (4), a generator casing (5).
Comprise a permanent magnet (6), a coil (7), a base plate (8), a PCB circuit board (9), a shell (10), one (11), a bearing (12), a pad (13), some screws (14) in this casing (5).
This handgrip (1) is installed in through handgrip fixed head (2) and press-fits on the gear (4), and this press-fits gear (4) and also is installed on the shell (10) through handgrip fixed head (2).The diameter of this driven gear (3) will be much smaller than the diameter that press-fits gear (4), and this driven gear (3) crosses the middle part that (11) are fixed on shell (10), this driven gear (3) with press-fit gear (4) and remain on same plane and meshing mutually.This shell (10) is through the fixing casing (5) that forms generator of some screws (14) and base plate (8).This PCB circuit board (9) is installed on the base plate (8).This axle (11) is installed on the bearing (12), and this bearing (12) is fixed on the base plate (8) through some screws (14), and in the bottom of this bearing (12) pad (13) is installed, and avoids base plate (8) and axle (11) directly to produce friction, to increase the service life.This permanent magnet (6) around coil (7) be installed in shell (10) inwall around, this coil (7) is installed in the casing (5) of generator through some screws (14) around bearing (12).
Its operation principle is following: when hand handgrip and the gear driven driven gear that press-fits that is installed together of handgrip rotate; Because this press-fits the diameter of the diameter of gear much larger than driven gear; Press-fit gear rotate a circle quite and driven gear rotate some circles; Under the slow-speed of revolution, can drive driven gear and rotate faster so it press-fits gear; This driven gear rotation can drive axle also can drive coil rotation generating with the bearing rotation while, and this electric energy can be done charging to products such as the broadcast receiver of being with storage battery, flashlights through the output of PCB circuit board.
