Technical Field

Background
Wireless controllers have been very commonly used in different electronic control devices. For example, for a common household or office appliance to be equipped with a wireless controller, the conventional wireless controller must be driven using a battery as a power source. Therefore, after the life cycle of the battery is over, the user must frequently replace the old battery with a new one.
Most of the electric appliances for home or office use are wired switches, which are inconvenient for wiring. When the wireless switch is adopted, the battery is still adopted for driving. The user must frequently replace the battery after the life cycle of the battery is over. In particular, the user must detach the wireless switch from the wall and disassemble the housing of the wireless switch to clean and replace the battery. Otherwise, the acid solution in the battery will leak out, which pollutes the environment and shortens the service life of the battery. Therefore, a cleaner and more reliable power source is needed for wireless switches or other small electronic devices.

As shown in fig. 1 to 6, in the first embodiment of the kinetic energy generator according to the present invention, the kinetic energy generator includes a magnetic circuit system 10, a driving device 20, and a coil 30, the magnetic gap 14 is formed in the magnetic circuit system 10, the coil 30 is fixedly disposed on the driving device 20, and can reciprocate in the magnetic gap 14 under the driving of the driving device 20 to generate an induced current, so that the kinetic energy generator according to the present invention achieves the effect of generating electricity.
As shown in the figure, the magnetic circuit system 10 forms an annular magnetic gap 14, and the coil 30 and the magnetic gap 14 can generate relative displacement, so that the coil generates induced current, and power generation operation is performed. Specifically, the position of the magnetic gap 14 may be fixed and the coil 30 may move, or the position of the coil 30 may be fixed and the position of the magnetic gap 14 may change, so that the relative displacement between the coil 30 and the magnetic gap 14 is generated. More specifically, the magnetic circuit system 10 may be fixed and the driving device 20 is used for driving the coil 30 to move, or the coil 30 may be fixed and the driving device 20 is used for driving the magnetic circuit system 10 to move, so that the coil 30 and the magnetic circuit system 10 generate relative displacement, and the coil 30 rapidly reciprocates in the magnetic gap 14, so that the coil 30 is rapidly cut by the magnetic induction lines of the magnetic circuit system 10, and an induced current is generated in the coil 30 based on the electromagnetic induction principle. In the preferred embodiment of the present invention, the driving device 20 is used for driving the coil 30 to generate an induced current.
Specifically, as shown in fig. 2 and 3, in the first embodiment of the present invention, the magnetic circuit system 10 includes a top magnetic conductive plate 13, a permanent magnet 12 and a bottom magnetic conductive plate 11, the bottom magnetic conductive plate 11 has a groove 111, the permanent magnet 12 is disposed in the groove 111 of the bottom magnetic conductive plate 11 and has a gap with a peripheral sidewall of the bottom magnetic conductive plate 11, and the top magnetic conductive plate 13 is attached to a top surface of the permanent magnet 12, so that the top magnetic conductive plate 13 and the permanent magnet 12 form the annular magnetic gap 14 with densely distributed magnetic induction lines in the bottom magnetic conductive plate 11.
Furthermore, in the first embodiment of the present invention, the bottom magnetic conductive plate 11 is a cylindrical magnetic conductive plate with a U-shaped longitudinal section, so that the groove 111 is also cylindrical, the permanent magnet 12 is cylindrical, and is located in the groove 111 of the cylindrical bottom magnetic conductive plate 11, and the outer diameter of the permanent magnet 12 is smaller than the diameter of the groove 111, and the top magnetic conductive plate 13 is also cylindrical and has the same outer diameter as the outer diameter of the permanent magnet 12, so that the magnetic gaps 14 with densely distributed magnetic induction lines can be formed between the top magnetic conductive plate 13 and the bottom magnetic conductive plate 11.
As a variation of the first embodiment of the present invention, the top magnetic conductive plate 13 and the bottom magnetic conductive plate 11 may also have other shapes or structural forms, for example, the bottom magnetic conductive plate 11 is a hollow cuboid with a U-shaped longitudinal section, so long as the top magnetic conductive plate 13 and the permanent magnet 12 can form the magnetic gaps 14 with densely distributed magnetic induction lines in the bottom magnetic conductive plate 11. The specific embodiments of the present invention are not limited thereto, and all that is required is that the same or similar technical means as the present invention is adopted and the same or similar technical features as the present invention are achieved, and all that is included in the scope of the present invention.
In addition, a person skilled in the art may also determine the formation mode of the magnetic gap 14 according to actual conditions, and the invention is not limited to the specific embodiment as long as the magnetic gap 14 can be generated, and the kinetic energy power generation device of the invention is within the protection scope.
As shown in fig. 1 and 4, in the first embodiment of the kinetic energy generating apparatus of the present invention, the driving device 20 includes a driver, which is implemented as a magnetic conductor 21 made of magnetically attractive magnetic conductive material in this embodiment. It is understood that the driver may also be formed by coating a non-magnetic material with a magnetic conductive material, and the invention is not limited in this respect. In this preferred embodiment, the driver is embodied as an iron plate. The cross section of the coil 30 is O-shaped and is fixed to the bottom surface of the magnetizer 21, and when the magnetizer 21 is placed on the top surface of the top magnetizer 13, the coil 30 can be inserted into the magnetic gap 14. Due to the magnetic permeability of the magnetizer 21, when the magnetizer 21 is placed on the surface of the top magnetic plate 13, the magnetizer 21 is tightly adhered to the top surface of the top magnetic plate 13 by the attraction force of the permanent magnet 12 below the top magnetic plate 13, and the coil 30 is correspondingly positioned in the magnetic gap 14, and when the coil 30 leaves the magnetic gap 14 and is still positioned in the range of the magnetic adsorption field of the magnetic circuit system 10, the coil 30 can rapidly move back to be adhered to the top magnetic plate 13 again under the magnetic attraction force of the magnetic circuit system 10.
Fig. 4 to 6 are schematic views illustrating an operation process of the first embodiment of the kinetic energy generating device according to the present invention.
As shown in fig. 4, when the magnetizer 21 is attracted to the top surface of the top magnetic conductive plate 13 by the attraction force of the permanent magnet 12, the coil 30 is located in the magnetic gap 14, and the kinetic energy generating device is in a stationary state.
As shown in fig. 5, when the magnetic conductor 21 is driven by an external force F to move upward, the coil 30 follows the magnetic conductor 21 to move upward and is spaced apart from the magnetic gap 14. Meanwhile, since the magnetic conductor 21 is pulled downward by the permanent magnet 12, when the external force F attempts to separate the magnetic conductor from the top magnetic conductive plate 13, the potential energy is maintained due to the strong magnetic attraction of the permanent magnet 12, so that the coil 30 has potential energy.
As shown in fig. 6, when the external force F suddenly disappears, the magnetic conductor 21 will move downward rapidly under the magnetic attraction of the permanent magnet 12 to reset until it is attached to the surface of the top magnetic conductive plate 13 again. Meanwhile, the coil 30 fixedly arranged with the magnetizer 21 is driven by the magnetizer 21 to rapidly move downwards, so as to be inserted into the magnetic gap 14. And the rapid movement of the coil 30 in the magnetic gap 14 causes the coil 30 to be rapidly cut by the closely spaced magnetic induction lines in the magnetic gap, thereby generating the induced current in the coil 30. The induced current can be used to drive the corresponding device into operation.
Specifically, in the first embodiment of the present invention, the magnetic conductor 21 is an iron plate, and a person skilled in the art may alternatively change the type of the magnetic conductor 21 according to actual situations, for example, cobalt, nickel, and alloys thereof are selected. In addition, a person skilled in the art may modify the specific technical solutions according to the disclosure of the present invention, for example, if the coil 30 is fixed and the magnetic circuit system 10 is moved, the coil may be cut by the magnetic induction line in the magnetic circuit system 10 to generate a current, in other words, the current may be generated by cutting the coil 30 by the magnetic induction line in the magnetic circuit system 10, so that the present invention is within the scope of the present invention as long as the same or similar technical solution as the present invention is adopted and the same or similar technical effect as the present invention is achieved, and the specific embodiment of the present invention is not limited thereto.
In the first embodiment of the kinetic energy power generation device, the width of the magnetic gap 14 is between 0.5mm and 10mm, the number of turns of the coil 30 is between 50 and 800, and the wire diameter of the coil 30 is between 0.06mm and 0.5mm, and a person skilled in the art can determine the width of the magnetic gap 14, the number of turns of the coil 30, and the wire diameter of the coil 30 according to the requirement for the magnitude of electric energy, as long as the technical scheme same as or similar to the present invention is adopted and the technical effect same as or similar to the present invention is achieved, which all fall within the protection scope of the present invention, and the specific implementation manner of the present invention is not limited thereto.
It is noted that any means may be used by one skilled in the art to drive the coil 30 in a reciprocating motion in the magnetic gap 14 to generate the induced current. For example, the kinetic energy power generation device described in the present invention adopts the same or similar technical scheme, so as to solve the same or similar technical problems, and achieve the same or similar technical effects as the present invention, and all of them fall within the protection scope of the kinetic energy power generation device described in the present invention.
In addition, in the process that the driving device 20 drives the coil 30 to reciprocate in the magnetic gap 14, the coil 30 may return in the magnetic gap 14 by attraction force, the coil 30 may reciprocate in the magnetic gap 14 by elastic force, or the coil 30 may reciprocate in the magnetic gap 14 by inertia force, external force, or the like, which may be determined by those skilled in the art according to specific situations, and the specific embodiment of the kinetic energy power generation device according to the present invention is not limited thereto.
It should be emphasized that the kinetic energy generating device with the circuit board 22 becomes a wireless transmitter when the circuit board 22 is electrically connected to the kinetic energy generating device of the present invention and the induced current generated by the kinetic energy generating device can drive the circuit board 22 to start corresponding operation.
Specifically, the coil 30 is electrically connected to the circuit board 22, the circuit board 22 may integrate a series of circuit components 221, and the circuit board 22 may be fixed on the top side of the magnetizer 21 implemented as an iron plate, i.e. on the top side of the magnetic circuit system 10, so as to form a compact structure, as shown in fig. 4, but it may be the peripheral side of the magnetic circuit system 10, as long as it is electrically connected to the coil 30, as will be understood by those skilled in the art.
The induced current generated by the coil 30 will be converted to utility power by a voltage converter in the circuit board 22 to provide a power supply to the main control module of the circuit board. Meanwhile, when the circuit board 22 is integrally integrated with a high-frequency wireless rf circuit, the main control module can also generate a control command, and the control command is transmitted to various electronic devices through the high-frequency wireless rf circuit, so as to control the electronic devices. For example, when the control command is sent to an electronic control system, and the electronic control system can be used as an intelligent home control system, which is operatively connected to various electronic devices, such as a luminaire, a curtain control unit, an air conditioning control unit, an intelligent indicating unit, and the like, through a central control unit.
For example, in a typical application, the kinetic energy power generation device of the invention can be applied to a self-generating wireless switch, wherein the self-generating wireless switch is suitable for connecting any electronic equipment. The self-generating wireless switch provided with the kinetic energy power generation device of the present invention is a self-generating device that controls the electronic equipment in a switching manner. For example, the self-generating wireless switch according to the preferred embodiment is used to control a luminaire in a switching manner. It should be appreciated that the self-generating wireless switch is capable of activating and deactivating other electronic devices, such as televisions, refrigerators, and fans, for example, for home or office appliances.
In this embodiment of the present invention, a kinetic energy generating method is provided for supplying power to small electronic devices, such as a wireless switch, to form a wireless self-generating switch, the method comprising the steps of: the magnetizer 21 moves under the action of external force to drive the coil 30 connected with the magnetizer to leave the annular magnetic gap 14 of the magnetic circuit system 10 by a preset distance; and
when the external force disappears, the magnetizer 21 is attracted with the magnetic circuit system 10 again under the action of the magnetic absorption force of the magnetic circuit system 10, and meanwhile, the coil 30 returns to the magnetic gap 14, so that the coil 30 is cut by the magnetic induction line of the magnetic circuit system 10 and generates induction current for power generation.
In the above method, when the magnetic conductor 21 implemented as an iron plate is lifted upward as shown in the drawing by an external force to make the coil 30 separated from the magnetic gap 14 by a predetermined interval, the iron plate is pulled downward by the magnet to make the coil 30 have potential energy, and since the iron plate is normally attracted by the magnet, when the external force attempts to separate it from the magnet upward, the potential energy must be maintained by the strong attraction of the magnet. When the external force disappears suddenly, the iron plate can move downwards quickly under the action of the attraction force of the magnet until the iron plate is attracted with the magnet again. At the same time, the coil associated with the iron plate is also inserted rapidly downward into the magnetic gap 14, and the rapid movement of the coil causes the coil 30 to be cut rapidly by the magnetic induction wire, and an induced current is generated in the coil 30 according to the principle of electromagnetic induction.
For example, when the magnetic circuit breaker is applied to a wireless switch or other small electronic devices, it may be that the magnetizer 21 serving as the driver is moved away from the magnetic gap 14 by an external force of pressing, toggling, pushing, pulling, etc. by a user, and when the external force applied by the user suddenly disappears, the magnetizer 21 automatically returns to the initial attraction position by the magnetic attraction of the magnetic circuit system 10, so that the coil 30 reenters the magnetic gap 14, and thus the fast reciprocating motion of leaving and entering the magnetic gap 14 causes the magnetizer to be cut fast by the magnetic induction wires of the magnetic circuit system 10, so as to generate an induced current.
It can be understood that in this method, the magnetic conductor 21 is automatically reset by the magnetic action of the magnetic circuit system 10, so that the structure is simpler. In other embodiments, the magnetic conductor 21 may further be automatically reset by other means, such as driving the magnetic conductor 21 to reset by elastic deformation restoring performance, i.e. for example, the magnetic conductor 21 is connected to a spring, when the coil 30 leaves the magnetic gap 14, the spring is stretched or compressed, and when the external force disappears, the spring restores the original state to drive the magnetic conductor 21 to reset, so that the coil 30 returns to the magnetic gap 14, thereby completing the rapid reciprocating movement.
Based on the above inventive concept, the coil 30 is located in the magnetic gap 14 in the initial state, and the coil 30 is located in the magnetic gap 14, separated from the magnetic gap 14, and then returned to the magnetic gap 14 in one power generation operation. In other embodiments, it is also possible that the coil 30 is located outside the magnetic gap 14 in the initial state, and in one power generation operation, the coil 30 enters the magnetic gap 14 from being located outside the magnetic gap 14, and then exits the magnetic gap 14. In any case, the coil 30 is rapidly moved into and out of the magnetic gap 14, thereby causing an induced current in the coil 30.
As shown in fig. 7 to 10, which are specific application examples of the second embodiment of the wireless transmitter of the present invention, in this embodiment, similarly, the wireless transmitter includes a magnetic circuit system 10A, a driving device 20A and a coil 30A, the magnetic circuit system 10A includes a top magnetic conductive plate 13A, a permanent magnet 12A and a bottom magnetic conductive plate 11A, the permanent magnet 12A is disposed in a groove of the bottom magnetic conductive plate 11A and has a gap with a peripheral sidewall of the bottom magnetic conductive plate 11A, the top magnetic conductive plate 13A is attached to a top surface of the permanent magnet 12A, so that the top magnetic conductive plate 13A and the permanent magnet 12A form the ring-shaped magnetic gap 14A with closely-arranged magnetic induction lines in the bottom magnetic conductive plate 11A. In this embodiment, the wireless transmitter uses a spring plate 21A to drive the coil 30A to reciprocate in the magnetic gap 14A, so as to generate the induced current, and drives a circuit board 22A to transmit through the induced current.
Fig. 7 is a schematic diagram of an explosive structure of the first embodiment of the present invention. As shown in fig. 7, in the embodiment, the circuit board 22A is electrically connected to the coil 30 of the kinetic energy power generation device, wherein the driving device 20A of the kinetic energy power generation device includes a driver embodied as an elastic sheet 21A, the coil 30A is fixedly disposed on a bottom surface of the elastic sheet 21A, the circuit board 22A is fixedly disposed on a top surface of the elastic sheet 21A, the circuit board 22A is electrically connected to the coil 30A, and the coil 30A reciprocates in the magnetic gap 14A under the driving of the elastic sheet 21A, thereby achieving the power generation effect of the kinetic energy power generation device. It is understood that the circuit board 22A need not be fixed to the top surface of the elastic sheet 21A, but may be fixed to other positions of the whole power generation system.
In this embodiment, the elastic piece 21A has a first end 211A and a second end 212A, and the first end 211A has a first fixing hole 2111A and a second fixing hole 2112A. The kinetic energy power generation device in this embodiment of the present invention further includes a base 40, the base 40 is fixedly provided with a first fixing seat 41 and a second fixing seat 42, the first fixing seat 41 and the second fixing seat 42 have the same height, and the elastic sheet 21A is respectively fixed to the first fixing seat 41 and the second fixing seat 42 through the first fixing hole 2111A and the second fixing hole 2112A, so as to be fixed to the base 40. In other words, under the support of the first fixing seat 41 and the second fixing seat 42, the elastic sheet 21A not only can achieve relative fixation with the base 40, but also can maintain a horizontal position without external force, and when external force is applied, the second end 212A of the elastic sheet 21A can move relative to the first end 211A of the elastic sheet 21A.
That is, the proximal end of the spring plate 21A is fixed in place by one or more fixing bases 41 and 42, while the bottom surface of the distal end fixes the coil 30A. The distal end of the spring plate, i.e., the second end 212A, can rotate with the proximal end thereof, i.e., the first end 211A, as a fulcrum, so that the spring plate can be automatically reset. That is, unlike the above-described embodiment in which the coil 30 is restored by the magnetic attraction, in this embodiment of the present invention, the coil 30A is automatically restored by the elastic restoration performance of the elastic piece 21A.
The magnetic circuit system 10A is located below the second end 212A of the spring plate 21A, and the heights of the first fixing seat 41 and the second fixing seat 42 can ensure that the coil 30A is just driven to be located in the magnetic gap 14A formed by the magnetic circuit system 10A when the spring plate 21A is at rest. In other words, when the spring plate 21A is at rest without external force, the height thereof is about the same as the height of the magnetic circuit system 10A, so as to ensure that the coil 30A can be located in the magnetic gap 14A formed by the magnetic circuit system 10A when the external force on the spring plate 21A disappears, thereby providing the kinetic energy power generation device with the power generation function.
In addition, the second end 212A of the spring plate 21A is shaped to secure the O-ring 30A to the bottom surface thereof. Preferably, the second end 212A of the spring plate 21A is circular, and the circular second end 212A is an enlarged portion having an outer diameter larger than that of the coil 30A, so that the coil 30A can be stably fixed to the bottom surface of the second end 212A of the spring plate 21A. The second end 212A of the resilient plate 21A further has a protrusion 2121A, and the protrusion 2121A is located at a side of the second end 212A of the resilient plate 21A for facilitating the operation of the user. It will be appreciated by persons skilled in the art that the shapes described above are by way of example only and are not limiting to the invention.
Fig. 8 to 10 are schematic diagrams illustrating a power generation process of the wireless transmitter according to this embodiment of the present invention.
As shown in fig. 8, when no external force acts on the spring plate 21A, the second end 212A of the spring plate 21A and the coil 30A are located above the magnetic circuit system 10A, and the coil 30A is located in the magnetic gap 14A formed by the magnetic circuit system 10A. At this time, the entire kinetic energy power generation device is in a stationary state.
As shown in fig. 9, when an external force F1 is applied to the protrusion 2121A of the second end 212A of the spring plate 21A, the coil 30A is applied to the top of the magnetic gap 14A along with the second end 212A of the spring plate 21A. At this time, since the first end 211A of the resilient plate 21A is fixed to the first fixing seat 41 and/or the second fixing seat 42 on the base 10, when the second end 212A of the resilient plate 21A is acted upward by the external force F1, the second end 212A of the resilient plate 21A has reverse potential energy due to upward deformation.
As shown in fig. 10, at this time, if the external force F1 disappears, the stress on the protrusion 2121A of the second end 212A of the elastic piece 21A is released, so that the second end 212A of the elastic piece 21A moves downward rapidly under the action of the elastic force. The coil 30A is also quickly reset into the magnetic gap 14A along with the quick downward movement of the second end 212A of the elastic piece 21A, and when the coil 30A is quickly reset into the magnetic gap 14A, the coil is quickly cut by the magnetic induction lines densely distributed in the magnetic gap 14A, and finally the induced current is generated and transmitted to the circuit board 22A, so that the circuit board 22A is driven to perform corresponding wireless transmission work.
As a variation of this embodiment, a person skilled in the art may modify the structure and shape of the elastic sheet 21A and the material of the elastic sheet 21A according to actual situations or specific requirements, and as long as the wireless transmitter described in the present invention adopts the same or similar technical means, the same or similar technical problems as the present invention are solved, and the same or similar technical effects as the present invention are achieved, which all fall within the protection scope of the present invention, and the specific implementation manner of the present invention is not limited thereto.
In the wireless transmitter of the present invention, the circuit board 22A is a high frequency wireless transmitting circuit board, and a series of circuit board elements 221A and a radio frequency module (RF module) (not shown, the same shall apply hereinafter) are integrated in the high frequency wireless transmitting circuit board, that is, the coil 30A in the kinetic energy generating device is electrically connected to the high frequency wireless transmitting circuit board. When the coil 30A in the kinetic energy power generation device is cut by the magnetic induction lines densely distributed in the magnetic gap 14A to generate an induced current, the induced current drives the high-frequency wireless transmission circuit board with the circuit board element 221A and the RF radio frequency module to emit a high-frequency radio wave, thereby controlling the electronic device to operate.
The spring plate 21A as the driver in this embodiment of the present invention pries the coil 30A in a lever-like manner to generate a rapid reciprocating displacement, so that the coil 30 generates an induced current. It is understood that, in the above structure, in the initial state, when the coil 30A is located in the magnetic gap 14A, when the protrusion 2121A is lifted upwards to rotate the second end 212A of the elastic piece 21A upwards with the first end 211A as a fulcrum, the coil 30A leaves the magnetic gap 14A and the elastic piece 21A accumulates potential energy, and when the external force disappears, the elastic piece 21A automatically resets to drive the coil 30A to enter the magnetic gap 14A again, so that the coil 30A is rapidly cut by the magnetic induction lines of the magnetic circuit system 10A to generate an induced current. It is understood that, in another embodiment, the height of the fixing bases 41 and 42 may be greater than that of the magnetic circuit system 10A, so that in the initial state, the coil 30A is located outside the magnetic gap 14A, when the protrusion 2121A is pressed downward, the second end 212A of the spring plate 21A rotates downward with the first end 211A as a fulcrum, the coil 30A enters the magnetic gap 14A and the spring plate 21A accumulates potential energy, and when the external force disappears, the spring plate 21A automatically rotates upward to return to the original position, so as to drive the coil 30A to leave the magnetic gap 14A, and thus the coil 30A is rapidly cut by the magnetic induction lines of the magnetic circuit system 10A to generate an induced current because the coil 30A rapidly enters and leaves the magnetic gap 14A.
Accordingly, in this embodiment of the present invention, there is provided a kinetic energy power generation method for supplying power to small electronic devices, such as typically a wireless switch, to form a wireless self-generating switch, the method comprising the steps of:
the second end 212A of the spring plate 21A performs lever motion with the first end 211A as a fulcrum under the action of an external force and generates elastic deformation to drive the coil 30 connected with the spring plate to leave the annular magnetic gap 14A of the magnetic circuit system 10A by a predetermined distance; and
when the external force action disappears, the elastic sheet 21A automatically resets and drives the coil 30A to automatically reset, wherein the coil 30A is cut by the magnetic induction line of the magnetic circuit system 10A to generate induction current for generating electricity.
Or the method comprises the following steps:
the second end 212A of the elastic sheet 21A performs lever motion with the first end 211A as a fulcrum under the action of external force and generates elastic deformation, so as to drive the coil 30A connected with the elastic sheet to enter the annular magnetic gap 14A of the magnetic circuit system 10A; and
when the external force action disappears, the elastic sheet 21A automatically resets and drives the coil 30A to leave the magnetic gap 14A, wherein the coil 30A is cut by the magnetic induction line of the magnetic circuit system 10A to generate induction current for generating electricity.
It should be noted that the external force applied to the elastic sheet 21A may be a direct action from the user, or may be other indirect actions, as long as the external force is capable of displacing the distal end of the elastic sheet 21A, so as to accumulate the elastic potential energy.
It is understood that when the coil 30A is fixed and the driver of the driving device is used to drive the magnetic circuit system 10A, the distal end of the elastic piece 21A may be fixed to the magnetic circuit system 10A, so that when the elastic piece 21A is rotated lever-like with its distal end opposite to its proximal end under the action of external force, the coil 30A is not changed in position and the magnetic circuit system 10A may be driven to move, and when the external force suddenly disappears, the elastic piece 21A automatically resets due to the elastic restoring performance, thereby driving the magnetic circuit system 10A to automatically reset, so that the magnetic gap 14A of the magnetic circuit system 10A and the coil 30A generate relative rapid reciprocating displacement, thereby generating an induced current in the coil 30A. Similarly, when the spring plate 21A is used to drive the magnetic circuit system 10A, in an initial state, the coil 30A may be located in the magnetic gap 14A, or may be located outside the magnetic gap 14A, and in a repeated cycle, the magnetic gap 14A may be moved away from the coil 30A first and then returned quickly, or the magnetic gap 14A may be sleeved around the coil 30A and then moved away from the coil 30A quickly by the movement of the magnetic circuit system 10A.

The third embodiment of the wireless transmitter is different from the first embodiment in that in the third embodiment, a cam is used to drive the coil 30B to reciprocate up and down in the magnetic gap 14B by the relative circular rotation motion of the cam, so as to generate the induced current, and the circuit board 22B is driven by the induced current to perform the corresponding transmitting operation.
In detail, in the third embodiment of the wireless transmitter according to the present invention, the driving device 20B comprises a driver including a cam, the cam is cylindrical and includes an upper cam 201B and a lower cam 202B, the upper cam 201B has a first space 2011B, and the lower cam 202B has a second space 2021B. A plurality of continuous first convex teeth 2012B are arranged on the periphery of the upper cam 201B, and each first convex tooth 2012B includes a first upper end 20121B and a first lower end 20122B. Similarly, the lower cam 202B is provided with a plurality of second teeth 2022B engaging with the first teeth 2012B, respectively, on the periphery thereof, and each of the second teeth 2022B includes a second upper end 20221B and a second lower end 20222B, respectively. When each of the first teeth 2012B is engaged with the second tooth 2022B, the first upper end 20121B of the first tooth 2012B is located at the second upper end 20221B of the second tooth 2022B, and the first lower end 20122B of the first tooth 2012B is located at the second lower end 20222B of the second tooth 2022B; when the upper cam 201B performs a circular rotation motion with respect to the lower cam 202B, the first upper end 20121B and the first lower end 20122B of the first tooth 2012B of the upper cam 201B slide along the second upper end 20221B and the second lower end 20222B of the second tooth 2022B of the lower cam 202B, respectively, so that the upper cam 201B performs a reciprocating up-and-down motion with respect to the lower cam 202B.
As shown in fig. 12 and 13, the wireless transmitter further includes a circuit board 22B, and the circuit board 22B is fixedly disposed on the upper cam 201B. Specifically, at least one buckle 2013B is disposed on the periphery of the upper cam 201B, and the circuit board 22B is provided with the same number of buckle holes 222B on the periphery thereof, so that the circuit board 22B is fixed to the upper cam 201B by the combination of the buckle 2013B and the buckle holes 222B. In this embodiment of the wireless transmitter of the present invention, three of the buckles 2013B are disposed on the periphery of the upper cam 201B, and three of the buckle holes 222B are also disposed at corresponding positions of the circuit board 22B for respectively cooperating with the buckles 2013B, so that the circuit board 22B and the upper cam 201B are fixed together. It is understood that the latch 2013B may be disposed on the circuit board 22B, and the latch hole 222B may be disposed on the upper cam 201B. Of course, the circuit board 22B and the upper cam 201B may be fixed by other connection methods, and the invention is not limited in this respect.
The coil 30B is fixed to the bottom surface of the circuit board 22B and located in the first space 2011B of the upper cam 201B, the top surface of the circuit board 22B further includes a magnetizer 21B, and the magnetizer 21B is fixed to the top surface of the circuit board 22B and may be made of a magnetic conductive material, such as an iron plate, or formed by wrapping a magnetic conductive material with a magnetic non-conductive material. Meanwhile, in this modified embodiment of the wireless transmitter according to the present invention, the magnetic circuit system 10B has the same structure as that of the magnetic circuit system 10 in the first embodiment of the kinetic energy power generator, the magnetic circuit system 10B is located in the second space 2021B of the lower cam, and when the upper cam 201B and the lower cam 202B are engaged, the coil 30B is located in the magnetic gap 14B formed by the magnetic circuit system 10B.
It is understood that the magnetizer 21B may be located on the bottom surface of the circuit board 22B, or may be integrally formed with the circuit board 22B, as long as it can generate a magnetic attraction force with the magnetic circuit system 10 and automatically reset the cam to the engaged state. In addition, it is also possible that the magnetizer 21B is fixed to the upper cam 201, and the circuit board 22B is fixedly connected to the magnetizer 21B.
Fig. 14 to 16 are schematic diagrams illustrating the operation of a third embodiment of the wireless transmitter according to the present invention.
As shown in fig. 14, in the initial position, since the magnetizer 21B receives the downward attraction force of the permanent magnet 12B in the magnetic circuit system 10B, and at the same time, since the circuit board 22B is fixed to the upper cam 201B and the circuit board 22B is fixedly disposed to the magnetizer 21B, the upper cam 201B is completely engaged with the lower cam 202B by the magnetic attraction force of the magnetizer 21B and the permanent magnet 12B. At this time, the coil 30B is in the magnetic gap 14B of the magnetic circuit system 10B, and is in a stationary state.
As shown in fig. 15, when the lower cam 202B is kept stationary and an external force F2 is applied circumferentially to the upper cam 201B, the first tooth 2012B of the upper cam 201B starts to separate along the second tooth 2022B of the lower cam 202B; when the first upper end 20121B of the first tooth 2012B of the upper cam 201B corresponds to the second lower end 20222B of the second tooth 2022B of the lower cam 202B, the coil 30B is disengaged from the magnetic gap 14B and the distance between the upper cam 201B and the lower cam 202B reaches a maximum value.
As shown in fig. 16, after the peak of the teeth, the magnetizer 21B is influenced by the magnetic force of the magnetic circuit system 10B, and when the upper cam 201B continues to rotate rapidly, the first convex tooth 2012B on the upper cam 201B and the second convex tooth 2022B on the lower cam 202B are re-engaged, and at this time, the coil 30B falls into the magnetic gap 14B again with the rapid downward movement of the upper cam 201B, and is rapidly cut by the magnetic induction lines densely distributed in the magnetic gap 14B. According to the principle of electromagnetic induction, when the upper cam 201B moves down rapidly so that the coil 30B is cut rapidly by the magnetic induction lines densely distributed in the magnetic gap 14B, an induced current is generated in the coil 30B. The induced current can drive the circuit board 22B to work accordingly.
It should be noted that, in the third embodiment of the wireless transmitter according to the present invention, the rotation directions of the upper cam 201B and the lower cam 202B can be adjusted according to actual conditions, as long as the upper cam 201B and the lower cam 202B can perform a circular motion along the first protruding tooth 2012B and the second protruding tooth 2022B, and further drive the coil 30B to perform a reciprocating motion in the magnetic gap 14B, so as to generate an induced current.
In addition, in the third embodiment of the wireless transmitter according to the present invention, the magnetic conductor 21B is embodied as an iron plate, and those skilled in the art may also determine the specific material of the magnetic conductor 21B according to practical situations, for example, the magnetic material with a magnetic pole opposite to that of the magnetic circuit system 10B may also be adopted, as long as the magnetic property is within the protection scope of the present invention, and the embodiments of the present invention are not limited thereto.
The person skilled in the art can also adjust the motion relationship between the upper cam 201B and the lower cam 202B according to the customer's needs or actual conditions. In other words, the person skilled in the art can arrange that the upper cam 201B is stationary and the lower cam 202B carries the second tooth 2022B along the first tooth 2012B in a circular motion relative to the upper cam 201B. That is, one skilled in the art can fix the coil 30B, and the magnetic circuit system 10B reciprocates relative to the coil 30B to generate the induced current. The specific implementation of the wireless transmitter of the present invention is not limited thereto, and all that is needed is to adopt the same or similar technical solution as the present invention and achieve the same or similar technical effects as the present invention, and all that is included in the protection scope of the wireless transmitter of the present invention.
In a third embodiment of the wireless transmitter according to the present invention, the circuit board 22B is a high frequency wireless transmitting circuit board, in which a circuit board element 221B and a radio frequency module (RF module) (not shown, the same applies below) are electrically connected, i.e., the coil 30B of the kinetic energy generating device is electrically connected to the high frequency wireless transmitting circuit board. When the coil 30B in the kinetic energy power generation device is cut by the magnetic induction lines densely distributed in the magnetic gap 14B to generate an induced current, the induced current drives the high-frequency wireless transmission circuit board with the circuit board element 221B and the RF radio frequency module to emit a high-frequency radio wave, thereby controlling the electronic device to operate.
It should be emphasized that, in the third embodiment of the wireless transmitter of the present invention, the shape and structure of the cam, such as an oval or a ring, may be modified by those skilled in the art according to the actual situation, as long as the coil 30B is driven to reciprocate in the magnetic gap 14B to generate the induced current, which all fall within the protection scope of the present invention, and the specific embodiment of the present invention is not limited thereto.
Accordingly, in this embodiment of the present invention, there is provided a kinetic energy power generation method for supplying power to small electronic devices, such as typically a wireless switch, to form a wireless self-generating switch, the method comprising the steps of:
the upper cam 201B starts to separate from the lower cam 202B under the action of an external force, and drives the circuit board 22B connected with the upper cam to move, so that the coil 30 assembled on the circuit board 22B is away from the annular magnetic gap 14B of the magnetic circuit system 10B by a predetermined distance; and
when the external force action disappears, the magnetic attraction between the magnetizer 21B and the magnetic circuit system 10B automatically resets the upper cam 201B and the circuit board 22B and drives the coil 30B to automatically reset, wherein the coil 30B is cut by the magnetic induction wire of the magnetic circuit system 10B to generate an induced current for generating electricity.
Or the method comprises the following steps:
the lower cam 202B starts to separate from the upper cam 201B under the action of an external force, and drives the magnetic circuit system 10B connected with the lower cam to move, so that the coil 30B assembled on the circuit board 22B is away from the annular magnetic gap 14B of the magnetic circuit system 10B by a preset distance; and
when the external force action is eliminated, the lower cam 202B automatically resets to engage with the upper cam 201B and drives the magnetic circuit system 10B to automatically reset, so that the coil 30 enters the magnetic gap 14B of the magnetic circuit system 10B, wherein the coil 30A is cut by the magnetic induction wire of the magnetic circuit system 10B to generate induction current for generating electricity.

Specifically, in the method of driving the coil to reciprocate in the magnetic gap through the elastic sheet, the coil and the elastic sheet are fixed, and then the coil reciprocates in the magnetic gap by using the elastic force of the elastic sheet, so as to achieve the purpose of generating power.
In the method for driving the coil to reciprocate in the magnetic gap through the seesaw, the middle of the seesaw is provided with the fulcrum, the seesaw can move on two sides under the action of the fulcrum, and then the coil and the seesaw are fixed together, so that when the seesaw moves up and down under the action of external force, the coil can also reciprocate in the magnetic gap under the driving of the seesaw, and the purpose of power generation is realized.
It is worth noting that due to the particularity of the seesaw, as long as an external force acts on any side of the seesaw, both sides of the seesaw can move correspondingly, and only the movement directions are opposite, so that when the seesaw is used for driving the coils to move in the magnetic gaps, the coils and the magnetic gaps can be arranged on both sides of the seesaw, and the reciprocating movement of the seesaw can drive the coils on both sides of the seesaw to generate current. In other words, in the power generation method in which the coil is driven to reciprocate in the magnetic gap by the seesaw, thereby generating the induced current, the seesaw can generate the double induced current, thereby improving the power generation efficiency of the kinetic energy power generation method.
In the method of driving the coil to reciprocate in the magnetic gap by the cam, the cam is provided as a pair of upper and lower cams engaging with each other, the upper and lower cams are provided with continuous teeth thereon, respectively, the upper and lower cams are engaged by the teeth, and the upper and lower cams are relatively rotatable along the teeth.

Alternatively, in the manufacturing method of the kinetic energy power generator of the present invention, a seesaw is provided in the driving device, and the coil is driven to reciprocate in the magnetic gap by the seesaw. Specifically, the middle part of the seesaw is provided with a fulcrum part, two ends of the seesaw can move up and down under the action of external force through the fulcrum part, and the coil and the seesaw are fixed together, so that the coil can reciprocate in the magnetic gap along with the up-and-down movement of the two ends of the seesaw, and induced current is generated.
It is worth noting that, because the two ends of the seesaw move in two directions simultaneously under the action of the fulcrum parts, the two ends of the seesaw only move in opposite directions. In other words, the two ends of the seesaw can move simultaneously in opposite directions under the action of the external force once, and a person skilled in the art can arrange the coils and the magnetic gaps at the two ends of the seesaw respectively and fix the two coils with the two ends of the seesaw respectively, so that the coils at the two ends of the seesaw can be driven to move in the magnetic gaps simultaneously under the action of the external force once on the seesaw.
