C-shaped double-magnet micro power generation device and wireless switch with power generation device

Abstract

The invention discloses a C-shaped double-magnet micro power generation device and a wireless switch with the power generation device. The power generation device comprises a coil assembly and a permanent magnet assembly. The permanent magnet assembly comprises a first permanent magnet, a second permanent magnet and a C-shaped soft magnetic frame. The coil assembly comprises a soft magnetic plateand a coil, the soft magnetic plate can be rotatably arranged in a C-shaped cavity of the C-shaped soft magnetic frame relative to the permanent magnet assembly, and in an initial state, the left endand the right end of the soft magnetic plate are connected with the right end of the upper soft magnetic plate and the left end of the lower soft magnetic plate through second permanent magnets to form a first closed magnetic circuit; and 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 connected with theleft end of the upper soft magnetic plate and the right end of the lower soft magnetic plate through the first permanent magnets to form a second closed magnetic circuit. The wireless switch comprises a radio frequency control panel, a switch used for controlling electric equipment and a self-generating device, and a coil of the self-generating device is electrically connected with the radio frequency control panel.

Description

technical field [0001] The present invention relates to a power generating device, and more particularly, to a C-type double-magnet micro-generating device and a wireless switch having the power generating device. Background technique [0002] With the advancement of technology, wireless controllers have been widely used in various household appliances. Correspondingly, wireless switches that use wireless switches to control household appliances have appeared. 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. However, there are many problems in the use of existing wireless switches: 1. Electromagnetic 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...

[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. Electromagnetic 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
