In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in fig. 1 to 9, the preferred embodiment of the present invention is provided.

The following describes the implementation of the present invention in detail with reference to specific embodiments.

The self-generating wireless switch 1 provided in this embodiment can be used in cooperation with various electrical products, and the self-generating wireless switch 1 is used to control the turning on or off of the electrical products, for example, in this embodiment, it is used to control the turning on or off of a lamp, and of course, it can also be used to control the turning on or off of a television, a refrigerator, a fan, and the like.

In this embodiment, the self-generating wireless switch 1 includes a micro-generator 14, a control board and a seesaw 12, wherein the control board is used for sending a wireless control signal to the outside, and when the control board is powered on, the control board can send the wireless control signal to the outside, and further the wireless control signal is used for controlling the operation state of an external electrical product, such as on or off; the micro-generator 14 comprises a movably arranged magnet group 144 and a fixedly arranged coil group, the magnet group 144 comprises a permanent magnet 1443 and two magnetic conductive plates 1442, the two magnetic conductive plates 1442 are respectively arranged on two opposite side surfaces of the permanent magnet 1443, so that under the action of the permanent magnet 1443, the two magnetic conductive plates 1442 respectively form different magnetic poles; the coil assembly includes iron core 142 and the wire of winding outside iron core 142, and this wire electric connection control panel, and the winding forms coil 147 on iron core 142, like this, when magnetic field changes in iron core 142, according to the electromagnetic induction principle, then can form the alternating current in the wire.

The magnet group 144 is disposed outside the iron core 142, directly contacts with the iron core 142, can slide up and down relative to the iron core 142, and is disposed opposite to the central line of the coil 147, and the iron core 142 is disposed opposite to the magnet group 144, forming a structural form disposed between the two magnetic conductive plates 1442. Of course, the iron core 142 may also be disposed at an angle with the magnet assembly 144, so that the direction of the magnetic induction line passing through the iron core 142 may also be changed, and the specific arrangement may be determined according to actual needs.

The middle of the seesaw 12 is hinged to form a hinge center, so that the two ends of the seesaw can swing up and down around the hinge center, respectively, wherein one end of the seesaw is connected with the magnet group 144, so that the whole magnet group 144 moves up and down along with the seesaw operation of the up-and-down movement of the end of the seesaw 12, of course, the permanent magnet 1443 and the two magnetic conductive plates 1442 also move up and down simultaneously, so that the iron core 142 is switched over between being respectively aligned with the two magnetic conductive plates 1442, and the magnetic levels of the two magnetic conductive plates 1442 are different, so that the magnetic field formed in the iron core 142 changes along with the change of the magnetic field, and further, the conducting wire in the coil 147 generates alternating current to realize the power generation effect, so that the control board is electrified, and sends a wireless control signal to.

The principle of the above operation process is specifically explained as follows:

the iron core 142 has two functions, namely a magnetic conduction function and a magnetic field reversing function; referring to fig. 6, it is assumed that the magnetic pole of one plate 1442 of the two plates 1442 is an S pole, and the magnetic pole of the other plate 1442 is an N pole. Initially, the end face of the iron core 142 is attracted and contacted with the end face of a magnetic conductive plate 1442, and because the iron core 142 has a magnetic conductive function, the iron core 142 is equivalent to the extension of the length of the magnetic conductive plate 1442, so that the magnetic induction line of the magnetic field can penetrate through the coil 147, and the direction of the magnetic induction line can be approximately regarded as N-S, that is, the direction of the magnetic induction line penetrating through the iron core 142 is from a to B; referring to fig. 7, when the seesaw 12 swings to change the position of the magnet assembly 144, that is, the position between the magnet assembly 144 and the iron core 142 changes relatively, and the iron core 142 jumps from one side of one magnetic conductive plate 1442 to one side of the other magnetic conductive plate 1442, and jumps from the S pole to the N pole, the iron core 142 becomes instantly attracted to the other magnetic conductive plate 1442 and contacts the end face together, and also because of the magnetic conduction function of the iron core 142, the length of the iron core 142 is equivalent to the extension of the other magnetic conductive plate 1442, the magnetic induction lines will generate mutual attraction with the N pole through the iron core 142, and the direction of the magnetic induction lines in the iron core 142 can be approximately regarded as S-N, that is, the direction of the magnetic induction lines passing through the iron core 142 is from B to a; thus, through the up-and-down movement process of the magnet group 144, the relative position between the magnet group 144 and the iron core 142 changes, so that the direction of the magnetic induction line passing through the iron core 142 is reversed, the direction of the magnetic field in the iron core 142 is changed from the previous N-S to S-N, and the change of the magnetic induction line in the iron core 142 can enable the coil 147 sleeved outside the iron core 142 to generate induced current, thereby realizing the effect of self-generation.

Of course, the alternating current in the coil 147 is supplied to the control board after passing through the rectifying circuit, so that the control board sends out the wireless control signal.

According to the self-generating wireless switch 1 provided by the embodiment, the magnet group 144 moves up and down relative to the coil group through the up-and-down movement of the manual operation seesaw 12, so that mechanical energy at a moment is converted into electric energy, and further self-generation is realized to provide a power supply for the control board, and the effect that the control board sends a wireless control signal outwards is achieved; the self-generating wireless switch 1 has the advantages of reliability of a wired switch, better reliability, safety compared with the traditional switch, convenience of a remote switch, and no need of using a chemical battery, so that repeated resource waste and environmental pollution are avoided; in addition, wiring is not needed, raw materials such as electric wires and PVC pipes are greatly saved, and the lighting construction period is shortened; the switches can be randomly distributed at the later stage of lighting construction, so that the distribution is more reasonable; the structure is simple, the conversion between mechanical energy and electric energy can be realized through the swing of the seesaw 12, and the popularization and the application are convenient.

Of course, the self-generating wireless switch 1 may not include the seesaw 12 depending on the application, and may be connected to another external member by the magnet group 144 as long as the magnet group 144 can be moved up and down, or may be moved up and down by directly and manually operating the magnet group 144.

Specifically, the boss 131 may be penetrated through by a connecting shaft, and the middle portion of the lower surface of the seesaw 12 may be rotatably coupled to the rotating shaft, so that the end portion of the seesaw 12 may swing with respect to the rotating shaft.
