Embodiment 1

[0044] Embodiment 1 of the present invention provides a self-generating switching device, such as figure 2 , Figure 8 with Figure 15 As shown, it includes: a permanent magnet assembly 1 and a coil 4, the permanent magnet assembly 1 includes a first permanent magnet 11 and a second permanent magnet 12, and the first permanent magnet 11 and the second permanent magnet 12 are relatively fixedly arranged with the same poles The permanent magnet assembly 1 is coupled with the coil 4 and can move relative to the coil 4 , and when the position of the permanent magnet assembly 1 changes relative to the coil 4 , an induced voltage is generated by the coil 4 .

[0045] Wherein, when implementing the embodiment of the present invention in a specific application, the first permanent magnet 11 and the second permanent magnet 12 can adopt a ring structure, a strip structure, a column structure, etc., but, through actual tests, the permanent magnet of the ring structure The magnet can b...

Embodiment 2

[0058] The embodiment of the present invention is based on the first coupling method between the permanent magnet assembly 1 and the coil 4 proposed in Embodiment 1, and further aims at the occurrence of the permanent magnet assembly 1 involved in the embodiment 1 relative to the coil 4 The change of position, and the relative fixed arrangement of the first permanent magnet 11 and the second permanent magnet 12 with the same polarity give a description of a feasible implementation solution. Such as figure 2 with image 3 Said, the permanent magnet assembly 1, in addition to including the first permanent magnet 11 and the second permanent magnet 12, also includes a permanent magnet fixture 13, and the permanent magnet fixture 13 is used to complete the first permanent magnet 11 and the second permanent magnet 12. The second permanent magnet 12 is relatively fixed with the same pole, specifically:

[0059] The first permanent magnet 11 and the second permanent magnet 12 are o...

Embodiment 3

[0075] The embodiment of the present invention is based on the second coupling method between the permanent magnet assembly 1 and the coil 4 proposed in the first embodiment, and further aims at the occurrence of the permanent magnet assembly 1 involved in the first embodiment relative to the coil 4 The change of position, and the relative fixed arrangement of the first permanent magnet 11 and the second permanent magnet 12 with the same polarity give a description of a feasible implementation solution. Such as Figure 8 Shown, in the embodiment of the present invention:

[0076] The coil 4 is arranged on the outer ring of the mold 41 having two through holes, wherein the first through hole 411 of the mold 41 is used to pass through the first permanent magnet 11 and the second permanent magnet in the first assembly 12; the second through hole 412 of the mold 41 is used to pass through the bottom plate of the U-shaped limiting groove 5 . Wherein, the installation of the mold ...

Abstract

The invention relates to the technical field of self-generating switches, and provides a self-generating switch device. The self-generating switch device comprises a permanent magnet assembly and a coil. The permanent magnet assembly consists of a first permanent magnet and a second permanent magnet. The same poles of the first permanent magnet and the second permanent magnet are arranged in a relatively fixed manner. The permanent magnet assembly and the coil are coupled to each other. The permanent magnet assembly and the coil can move relative to each other. When the permanent magnet assembly and the coil move relative to each other, the coil generates an induced voltage. Through the pair of permanent magnets with the same poles arranged in a relatively fixed manner and the coil coupledto the permanent magnets and through the change of the relative positions of the coil and the permanent magnets, the flux change rate of the coil during induction is improved, the generation power ofthe self-generating switch is improved, and the reliability and stability of long-distance response are ensured.

Description

【Technical field】 [0001] The invention relates to the technical field of self-generating switches, in particular to a self-generating switch device. 【Background technique】 [0002] With the popularity of the concept of green environmental protection, more and more attention has been paid to using less batteries and adopting technical solutions without batteries. Among them, taking the remote control field as an example, a self-powered remote control trigger terminal is used, combined with a peripheral powered response terminal, to form a solution that does not require battery power. [0003] As a result, the research and development of self-generating switching devices has also been paid more and more attention by the industry. Among them, such as figure 1 The self-generating switch shown is currently the most popular, because it requires a smaller switch workmanship and smaller size, so it is favored by major developers of self-generating devices. [0004] However, if fi...
