Embodiment Construction

[0040] A generator and a charging device provided by the present invention will be described in detail below with reference to the drawings and specific embodiments.

[0041] Most of the existing portable generator charging devices are hand-operated generators. When charging portable electrical appliances and electronic products, it is necessary to turn the generator charging device by hand for at least 30 minutes before the electronic and electrical products can be used for a certain period of time. power consumption. The purpose of the present invention is to provide an external power generation and charging device applied to milliamp level electronic appliances or directly embedded in the electronic appliances.

[0042] figure 1 shows a charging device with a resonant permanent magnet linear generator, such as figure 1 As shown, the charging device includes a permanent magnet linear generator, an electronic control system, a supercapacitor circuit and a battery. Among th...

Abstract

The invention provides a resonant type permanent magnet linear generator comprising stator structures and rotor structures. The rotor structures are arranged in magnetic shield casings of the stator structures and are positioned on the other sides of the magnetic shield casings, which are opposite to the stator structures. Each rotor structure also comprises a rotor substrate and a chute structure, wherein the rotor substrate is positioned between the chute structures; each chute structure comprises a reversing spring, a resonant spring, a U-shaped chute and a roll ball; the roll ball is arranged in the U-shaped chute; the rotor substrate is clamped in the U-shaped chute; the end part of the rotor substrate is in contact with the roll ball and slides in the U-shaped chute up and down; twoends of the two U-shaped chutes are correspondingly connected by a connecting plate; the reversing springs are respectively arranged at two ends of each of the two U-shaped chutes; and the resonant springs are respectively arranged between the substrates and two connecting plates. The resonant type permanent magnet linear generator disclosed by the invention has the advantages of simple structure, low cost, high generated electrical energy and easiness of constructing, carrying and integrating.

Description

technical field [0001] The invention relates to magnet power generation technology, more specifically, the invention relates to a linear generator, a charging device and a battery. Background technique [0002] Generally, portable electronic devices such as mobile phones, portable audio and video players, digital cameras, headlamps, etc. all require their own batteries to be used when they are away from an external power source. The batteries are generally made of precious metals such as nickel-cadmium and lithium batteries, which are expensive, difficult to recycle, and cause irreversible damage to the environment. Generally speaking, a charging connector is provided on the portable electronic device, and the portable electronic device is charged by connecting an external power source or an external charger through the connector without taking out the battery. [0003] For portable electronic devices, commercial power is usually used as an external power supply, but it is ...
