Self-generating device and wireless switch using same

Abstract

The invention discloses a self-generating device and a wireless switch using the same, which belong to the field of self-generating devices. The self-generating device comprises a coil assembly and apermanent magnet assembly. In the initial state, the left end and the right end of a soft magnetic plate make contact with a first permanent magnet and a second upper soft magnetic plate respectivelyto form a first closed magnetic circuit; after the soft magnetic plate rotates relative to the permanent magnet assembly, the left end and the right end of the soft magnetic plate are respectively contacted with the first upper soft magnetic plate and the second permanent magnet to form a second closed magnetic circuit; the direction of magnetic force lines passing through the soft magnetic platein the first closed magnetic circuit is opposite to that of magnetic force lines passing through the soft magnetic plate in the second closed magnetic circuit, and the coil generates power according to the electromagnetic induction principle. The wireless switch comprises a radio frequency control panel, a switch used for controlling electric equipment and the self-generating device, a coil of theself-generating device is electrically connected with the radio frequency control panel, and passive wireless switch control can be achieved.

Description

technical field [0001] The present invention relates to a power generating device and a wireless switch with the same, more specifically, to a self-generating device and a wireless switch using the same. Background technique [0002] With the advancement of science and technology, wireless controllers have been widely used in various household appliances. Correspondingly, there have been wireless switches that use wireless switches to control household appliances. The existing wireless switches can be divided into battery-type wireless switches. And self-generating (passive) wireless switches, the use of these wireless switches greatly facilitates people's daily life, but there are many problems in the use of existing wireless switches: 1. Battery-type wireless switches need to be installed For rechargeable batteries, because the switch is in a wireless connection state, the battery needs to be taken out and charged frequently. Because users often forget to charge, it is mis...

[0002] With the advancement of science and technology, wireless controllers have been widely used in various household appliances. Correspondingly, there have been wireless switches that use wireless switches to control household appliances. The existing wireless switches can be divided into battery-type wireless switches. And self-generating (passive) wireless switches, the use of these wireless switches greatly facilitates people's daily life, but there are many problems in the existing wireless switches: 1. Battery-type wireless switches need to be installed For rechargeable batteries, because the switch is in a wireless connection state, the battery needs to be taken out and charged frequently. Because users often forget to charge, it is misjudged as a power failure when using electrical appliances, which is inconvenient to use; 2. The existing self-generating wireless switch automatically The magnetic circuit of the generating device is complex, which is inconvenient to manufacture and increases the manufacturing cost; 3. The self-generating device in the existing self-generating wireless switch has low power generation efficiency, weak current, and insufficient power supply, resulting in unstable control of household appliances; 4. In some self-generating wireless switches, the components used for assembly between the permanent magnet assembly (permanent magnet and soft magnetic frame) and the coil assembly (soft magnetic plate and coil) are complex in structure and inconvenient to manufacture
