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 Halbach magnet array permanent magnet linear generator. A magnetic shielding shell serves as a rigid shell of the generator. A Halbach magnet array provides a sine wave magnetic field for the generator. A resonant spring converts mechanical energy into kinetic energy when producing vibration, so that a rotor assembly produces resonance and a coil winding cuts the magneticfield to produce an induced electromotive force. A sliding chute pedestal is provided with a guide slot which is paired with that of the rotor assembly, and balls are arranged in the matched guide slots to function in guiding the motion of the rotor assembly. A partition board is used for arranging a cushioning seat and fixing the sliding chute pedestal. A magnet array container made from a non-magnetic conducting material is used for enclosing and fixing magnets. The cushioning seat consists of a spring and a cushion pad to prevent the overtravel of the rotor assembly. The generator providedby the invention is simply structured, easy to construct and integrate, low in cost, high in generating capacity and convenient to carry.

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 ...
