Manual power generation device and emergency light provided with the same

Abstract

This invention discloses a hand electricity-generating device, in addition to its usage. Said device comprises housing, overdrive gear cluster, hand driving mechanism and generator, wherein the hand driving mechanism is connected with the inputting gear of the overdrive gear cluster, and the outputting gear of the overdrive gear cluster is connected with the generator; the generator comprises magnetic induction loops and cylinder magnet, wherein the cylinder magnet is arranged in the inner cylinder hole of the magnetic induction loops, and the cylinder magnet has a radial magnetic field contacted with the magnetic induction loops; the cylinder magnet is connected with the outputting gear of the overdrive gear cluster. Said invention can be widely used in emergency light, torch, mobile phone charging, or portable domestic appliances. íí

Description

technical field [0001] The invention relates to a manual power generating device and an emergency light with the power generating device, in particular to a manual power generating device with an improved generator. Background technique [0002] The manual power generating device in the prior art generally includes a housing, a speed-increasing gear set, a manual drive mechanism, and a generator. ,Such as Figure 11 , Figure 12 , Figure 13 , Figure 14 , Figure 15 As shown, the generator includes a magnetic induction coil and a planar magnetic ring, and the planar magnetic ring is provided with an axial magnetic field cut with the magnetic induction coil, because the magnetism of the planar magnetic ring is weak, and the planar magnetic ring is directly from the magnetic induction coil The cutting force of the magnetic field produced by it is not strong, so the current and voltage generated by the generator with this structure are not ideal, which greatly limits the p...

[0002] The manual power generating device in the prior art generally includes a housing, a speed-increasing gear set, a manual drive mechanism, and a generator. ,like Figure 11 , Figure 12 , Figure 13 , Figure 14 , Figure 15 As shown, the generator includes a magnetic induction coil and a planar magnetic ring, and the planar magnetic ring is provided with an axial magnetic field cut with the magnetic induction coil, because the magnetism of the planar magnetic ring is weak, and the planar magnetic ring is directly from the magnetic induction coil The cutting force of the magnetic field generated by it is not strong, so the current and voltage generated by the generator with this structure are not very ideal, which greatly limits the popularization and application of manual generators

[0003] At present, the emergency lights on the market are inseparable from the rule that they can be used after being charged by an external power supply (for example: they must be charged by a 220V external power supply for a long time before they can be used). The emergency lights themselves are emergency tools. During emergency use, it often occurs that you forget to charge or leave it for too long, resulting in a power outage, so that the emergency effect and function of the emergency light cannot be exerted, so the traditional emergency light will often bring inconvenience to the user.
