Example Embodiment

[0012] In this embodiment, refer to figure 1 , the staggered snap-type magnetic power generation device of the present invention comprises permanent magnet 4, soft magnetic material 3, iron core 2, spring 5 and coil 1; both ends of permanent magnet 4 are connected with soft magnetic material 3, pay attention to permanent magnet 4 and soft magnetic material The contact mode of 3 is that the end surface of permanent magnet 4 contacts the side surface of soft magnetic material 3, which is better than the magnetization effect of soft magnetic material 3 contacting the side surface of permanent magnet 4 end. The permanent magnet 4 magnetizes the soft magnetic material 3 at both ends, which is equivalent to guiding the two poles of the permanent magnet 4 to the same surface, forming a "C"-shaped magnet. One end of the iron core 2 faces the "C"-shaped magnet, and the other end is drawn out with a magnetic conductive material, and is divided into two ends, which are wound back toward ...

Abstract

The invention discloses a power generation device. The device comprises a permanent magnet, a soft magnetic material, an iron core and a coil, wherein two ends of the permanent magnet are connected with the soft magnetic material, two magnetic poles face towards the same direction, and a C-shaped magnet is formed, the iron core is an E-shaped magnetic circuit, and the coil is wound at a middle end of the E-shaped iron core, the C-shaped magnet and the E-shaped magnetic circuit are meshed in a staggering mode, and the connection and disconnection of the E-shaped magnetic circuit are controlled through the moving of the C-shaped magnet. According to the device, the disadvantages that various magnetic power generation devices with electrical motors serving as representatives are complex in structure and large in size are overcome, the mechanical energy which are in short stroke and can achieve translation can be converted into electrical energy, no pollution is caused, the device is particularly suitable for application occasions in the micro energy collection field, such as switches, pressing keys and vibration environment, and is one of ideal energy solutions of micro-power wireless sensor networks. The device is wide in application range, low in cost, small in size, free from pollution and simple in structure.

Description

technical field [0001] The invention relates to a magnetic generator, in particular to an interlaced magnetic generator. Background technique [0002] Existing magnetic generators have many kinds at present, and wherein the most commonly used is exactly generator. However, the magnetic generator represented by the generator has a large volume, which is not suitable for the environmental conditions with strict volume restrictions, and when the magnetic generator represented by the generator converts mechanical energy into electrical energy, the mechanical energy must be in the form of rotation. This just makes under some conditions, the magnetic generation device represented by generator is not applicable. Under the country's vigorous advocacy of energy saving and environmental protection, there are many special needs for micro-generating devices in the field of energy harvesting, which are often difficult to meet for traditional magnetic generating devices represented by ge...
