Description

[0001] The invention relates to the field of self-power generation, in particular to a self-resetting suspension magnetic generator, a power generation and reset method and an application thereof. BACKGROUND OF THE INVENTION

[0002] With the development of science and technology and the progress of society, more and more electrical equipment have entered people's lives, and the number of controllers used to control various types of electrical equipment has also increased accordingly, such as traditional controllers for controlling light switches. Switch controllers, most of which are wired switches, are inconvenient for wiring and will increase the installation cost of the corresponding electrical equipment and affect the aesthetics of the corresponding environment. With the development of science and technology, wireless control methods have become more and more common in people's lives, such as remote controls and other wireless control devices. It has become a habit for people to use remote controls and other wireless control devices to control corresponding electrical equipment. However, now some remote controls and other wireless control devices mostly use battery power to provide power. As a result, with the current trend of wireless control devices becoming popular, battery usage has also increased significantly. In many homes, in order to control various electrical devices , a variety of remote controls are scattered here and there. Each remote control needs to be equipped with a corresponding battery, and the batteries need to be replaced in batches after a corresponding period of use, which adds a lot of additional battery equipment costs. At the same time, driven by today's environmental protection concepts and policies, a large increase in the use of batteries is contrary to environmental protection concepts and policies. Moreover, battery replacement will also cause a waste of resources and environmental pollution, and is not in line with the green, environmentally friendly, and low-carbon principles, idea.

[0003] At present, passive technology is a recognized solution to solve the consumption and waste of batteries of this type of control equipment. For example, the Chinese invention patent with patent announcement number CN104901505B discloses a conversion structure and wireless electronic products that convert kinetic energy into electrical energy. However, these micro generator structures have the problem of being large in size, which cannot meet the needs of some smaller volumes, and the manufacturing precision is extremely high; in this patent, two magnetic conductive plates alternately collide with the connecting plate, resulting in a strong Impact noise; and this power generation method that relies on magnets hitting the magnetic conductive plate up and down has little impact on the magnetic force generated by the coil, and the power generation efficiency is low; and in this structure, the magnet group needs to be fixedly connected to the elastic piece, relying on the external mechanical structure to maintain left and right Balance is not a structure that can fix itself and maintain balance by just using its own magnetism. If it is unbalanced, the output energy will be unstable, so the structure is relatively complicated. The existing magnetic pole-switching micro-generators in passive technology are bistable and adopt the N-S two-magnetic pole switching driving method, that is, they have N poles adsorbed to the magnetic conductive plate and S poles adsorbed to the magnetic conductive plate. There are two stable states, and external force is used to switch between these two stable states to generate electrical energy. There is always a magnetic pole adsorbed on the magnetic conductive plate, which produces huge impact noise during operation. This kind of micro-generator has one stable state when it is pressed, and another stable state when it is pushed by an external force. If you want to implement a monostable state, you need to set up a special spring return mechanism, and the spring return mechanism is in addition to In addition to taking up space and cost, it also increases the reverse resistance when driving the micro-generator, doubling the force required when pressing the micro-generator; if a new technology is used, the spring return mechanism can be removed to remove the reverse resistance of the spring improves the pressing feel of the micro generator, and the power generated by the micro generator can be significantly increased under the same driving force. In the Chinese invention patent with patent announcement number CN112290739B, the concept of a monostable micro-generator without a return spring is proposed. However, the automatic reset effect of this structure is poor and it is not a truly fully-automatic reset micro-generator, in practical applications, if the movement stroke is greater than 0.5 mm, a return spring is still needed to assist reset, and this structure cannot generate enough driving force to automatically reset the buttons on the housing, so these defects must be improved. Specifically referring to Figure 1, the power generation device includes a driving device 100P and a generator 200P. The driving device 100P includes a driving bracket 10P, an energy storage device 20P, at least one brake 30P and at least one magnetic unit 40. The brake 30P is attracted to the magnetic unit 40, and the brake 30 conducts the magnetic force of the magnetic unit40P. Magnetic force, the driving bracket 10P includes a driving part 11P, at least one transmission part 12P extending from the driving part 11P, and at least one rotating shaft 13P, wherein in the initial state, the driving part 11P is attracted to the brake 30P, and the energy storage device 20P is provided in the driving part 11P. When the energy storage device 20P stores sufficient driving force, the energy storage device 20P drives the driving part 11P of the driving bracket 10P, so that the driving part 11P is disengaged from the brake 30P. The driving part 11P and the transmission part 12P are located on both sides of the rotating shaft 13P. When the driving part 11P receives sufficient driving force, the driving part 11P and the transmission part 12P take the rotating shaft 13 as the axis (fulcrum). Turn movement. The transmission part 12P is connected to the generator 200P in a driving manner. When the transmission part 12 moves, the transmission part 12P drives the generator 200P to generate induced electrical energy, thereby converting mechanical energy into electrical energy, which overcomes the need for many control devices to rely on due to the limitations of battery power supply.

[0004] However, in many small and micro application scenarios, the size of the existing power generation device still cannot meet the application requirements, resulting in many small and micro devices still relying on battery power supply. In detail, the power generation of the power generation device. The transmission part 12P pivots on the side of the generator 200P to form a change in the magnetic flux of the magnetic flux lines generated by the hollow coil 200P of the generator 200P to generate electropotential energy. In order to enable the transmission part 12 to move in the side of the generator 200P pivots, and the power generation device is provided with the driving part 11P and the rotating shaft 13P that drive the pivoting of the transmission part 12P to drive the transmission part 12P based on the lever principle and increase the power of the transmission part 12P. kinetic energy to ensure the power generation efficiency. At the same time, in order to reset the transmission part 12P, the power generation device also needs to be equipped with the energy storage device 20P and the brake 30P. The driving device 10OP located on the side of the generator 200P occupies a large part of the area. As a result, the size of the power generation device is large, the structure of the power generation device is complex, the components are numerous, and the manufacturing cost is high. Micro-optimization of the power generation device is extremely difficult, and the requirements for process accuracy are strict, so that the current power generation device cannot be further used. Miniature design.

[0005] In the era of smart homes, if you want to further reduce the size of the generator to adapt to some electrical appliance remote control applications with extremely short pressing strokes, you need to design a new structure to solve the problem that the size of the generator in the existing passive technology is still the same. Comprehensive defects include large size, heavy pressing force, loud pressing noise, and a pressing stroke as long as a piano key. Therefore, there is a need to develop a generator, that is, a power generation component, which must be very small in size and can solve the above defects. It is suitable for being soldered to a circuit board (PCB) by patch method and used as a micro power supply component.

[0006] In addition, in the power generation device of the Chinese invention patent with announcement number CN112290739B, the driving device 100P and the brake 30P are set up in a horizontal distribution. The magnetic field is not on the same axis and the coverage range is narrow, resulting in a small magnetic reset force. When there is a button outside the housing, there is insufficient reset force to link the button for reset movement, and the reset distance is greater than reliable reset cannot be guaranteed after 0.5 mm, so new technical solutions are needed to solve these defects.

[0127] The following description is provided to disclose the invention to enable those skilled in the art to practice the invention. The preferred embodiments in the following description are only examples, and other obvious modifications may occur to those skilled in the art. The basic principles of the invention defined in the following description may be applied to other embodiments, variations, improvements, equivalents and other technical solutions without departing from the spirit and scope of the invention.

[0130] In the description of the present invention, it should be noted that, unless otherwise clearly stated and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a fixed connection or a fixed connection. It is a detachable connection or an integral connection; it can be a mechanical connection or an electrical connection or it can communicate with each other; it can be a direct connection or an indirect connection through an intermediate medium; it can be an internal connection between two elements or two elements, interaction relationship. Forthose of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0131] The present invention provides a self-resetting suspended magnetic generator, wherein the overall size of the self-resetting suspended magnetic generator is Due to the size of its hollow coil, intuitively the size of the self-resetting suspended magnetic generator is less than the size of a one-yuan coin, so that the self-resetting suspended magnetic generator can be applied to many small and micro devices to break through Existing small and micro equipment has no choice but to rely on battery power supply due to the size limit of the generator. Moreover, the self-resetting suspended magnetic generator has high power generation efficiency, and its power generation can meet the power demand of the corresponding equipment.

[0132] Specifically, with reference to Figure 2, the structural principle of the self-resetting suspended magnetic generator is schematically illustrated. The self-resetting suspended magnetic generator 100 includes a suspended magnetic assembly 10 and a hollow coil 20, wherein the hollow coil 20 defines a hollow channel 201 , wherein the suspended magnetic component 10 is disposed in the hollow channel 201 where the hollow coil 20 objectively exists, and is relative to the hollow coil 20 along the hollow channel 201 Make axial movement to disturb the magnetic field lines of the hollow coil 20, thereby generating induced electric energy, wherein the self-resetting suspended magnetic generator 100 utilizes the objectively existing hollow channel 201 of the hollow coil 20 to arrange the Therefore, the overall size of the self-resetting suspended magnetic generator 100 is reduced to only the size of the hollow coil 20, overcoming the development bottleneck of miniaturization and miniaturization of existing power generation devices, and achieving the desired goal. The self-resetting suspended magnetic generator 100 is miniaturized and miniaturized. At the same time, due to the axial movement of the suspended magnetic component 10 along the hollow channel 201 relative to the hollow coil 20, in the hollow coil The displacement within the magnetic field line range of 20 is larger, which improves the power generation efficiency of the self-resetting suspended magnetic generator 100. The power generation efficiency of the self-resetting suspended magnetic generator 100 is compared with the existing pivoting motion type generator. The power generation efficiency of the power generation device is increased by at least 20% to 35% to meet the corresponding power supply needs.

[0133] In particular, since the suspended magnetic component 10 moves axially relative to the hollow coil 20 along the hollow channel 201, the magnetic field around the suspended magnetic component 10 will cover the hollow 360° Coil 20, therefore, compared to the prior art structure that uses a magnetic permeable plate to guide the magnetic field from one side of the magnet or a certain direction to act on the coil, the present invention has a higher utilization rate of the magnetic field and reduces the volume. At the same time, it also improves power generation efficiency.

[0134] It is worth mentioning that the suspended magnetic component 10 of the self-resetting suspended magnetic generator 100 is small in size and can automatically reset without using redundant reset devices, and the self-resetting suspended magnetic generator The suspended magnetic component 10 and the hollow coil 20 of the generator 100 operate independently, and there is no need to provide an interconnection mechanism between them. The suspended magnetic component 10 is presented to the hollow coil 20 only by magnetic attraction. The structural form of magnetic levitation in the hollow channel 201. It can be understood that the terms "suspended magnet", "levitation" and "magnetic levitation" in the present invention refer to the fact that the suspended magnet assembly 10 can realize the hollow channel 201 of the hollow coil 20 relative to the hollow The coil 20 moves axially to cause the hollow coil 20 to generate electrical energy, and the suspended magnetic component 10 can maintain the initial state in the hollow channel 201 of the hollow coil 20 by using magnetic attraction and only utilize the magnetic attraction, reset.

[0135] Referring to FIGS. 3 to 5B in detail, the specific structure of the self-resetting suspended magnetic generator 100 according to an embodiment of the present invention is schematically illustrated. Specifically, the self-resetting suspended magnetic generator 100 further It includes a housing 30, wherein the housing 30 has a top cover 31 and a power generation cavity 301 defined below the top cover 31, wherein the suspension magnetic assembly 10 includes a driving member 11 and a return member 12, At least one of the driving member 11 and the return member 12 is a permanent magnet, the hollow coil 20 is accommodated in the power generation cavity 301 , and the top cover 31 has a structure connected to the power generation cavity 201 A driving hole 311, wherein when the hollow coil 20 is accommodated in the power generation cavity 301, the driving hole 311 communicates with the hollow channel 201 to form a suspended magnetic channel, wherein the return member 12 is provided in the suspended magnetic channel, corresponding to the state where at least one of the driving member 11 and the return member 12 is a permanent magnet, and the return member 12 and the top cover 31 have magnetic attraction. It is attracted by the top cover 31 under the action of magnetic attraction, and is thus held in an initial position, in which the driving member 11 extends from the driving hole 311 of the top cover 31 into the suspended magnetic channel, and is When pressed hard, the return member 12 is driven to move in a direction away from the top cover 31 , that is, the return member 12 Electric energy is generated by disturbing the magnetic field lines of the hollow coil 20 to form changes in magnetic flux. Correspondingly, the return member 12 is suspended in the suspended magnetic channel under the magnetic attraction with the top cover 31, and then in the When the force of the driving member 11 is removed, the return member 12 returns to the initial position, thus again disturbing the magnetic flux lines of the hollow coil 20 to form changes in magnetic flux, and generating electrical energy again, so that the suspended magnetic component 10 moves back and forth in a suspended manner along the suspended magnetic channel, causing changes in magnetic flux to generate induced electric energy.

[0136] In particular, the return member 12 is driven by applying a push force to the return member 12. When the push force is greater than the magnetic attraction force between the return member 12 and the top cover 31,, under the dual force of pushing force and magnetic attraction, the return member 12 is clamped to move in a direction away from the top cover 31 in a suspended manner; that is to say, the return member 12 and the magnetic attraction force between the top covers 31 is the reset force, and the pushing force and the reset force are in opposite directions. Therefore, with the combination of these two forces, the return member 12 can be clamped in a suspended manner to maintain the desired position. The return member 12 is in a suspended state, so that the return member 12 can move in suspension without falling off at any time by relying only on the interaction of the above two forces without any fixed connections. When the pushing force is equal to the magnetic attraction force, the return member 12 can remain suspended in a suspended manner; when the pushing force is less than the magnetic attraction force, the return member 12 moves toward the top cover 31 in a suspended manner and resets. That is to say, when force is applied to the return member 12 , the force pushing the return member 12 and the magnetic force pushing the return member 12 back to its reset jointly act on the return member 12 , so that the return member 12 is forced to return. When the return member 12 is not fixed by a fastening device, the return member 12 can move in the suspended magnetic channel in a suspended manner only by the support and clamping of two interacting and opposite forces. , thereby forming the suspended magnetic movement state, suspended magnetic working state or suspended state of the return member 12 . It should be emphasized that if the return member 12 is not subject to the interaction of the above two forces to achieve an automatically resettable suspension movement, but is a bistable movement method in the prior art, and other reset forces need to be provided. To reset the return member 12, this method does not belong to the suspension movement method. In the present invention, even in the process of movement, the return member 12 is in a suspended state and is clamped by two opposite forces. When an external force is used to drive the return member 12 away from the top cover, the return thrust of the return member 12 can be felt from beginning to end, that is, the magnetic attraction between the return member 12 and the top cover 31 . When the external force is released at any time, the return force will Part 12 can be automatically reset quickly.

[0137] It is worth mentioning that when the return member 12 realizes the magnetic reset of the suspended magnetic assembly 10, it simultaneously forms a change in magnetic flux to generate electricity, killing two birds with one stone and further generating electricity while being reset to enhance the overall power generation efficiency of the self-resetting suspended magnetic generator 100 is described.

[0138] Further, the housing 30 includes a bottom cover 32, and the power generation cavity 301 is defined by the top cover 31 and the bottom cover 32, that is, the top cover 31 and the bottom cover 32 The power generation cavity 301 is formed between the top cover 31 and the bottom cover 32, the hollow coil 20 is accommodated between the top cover 31 and the bottom cover 32 , and the return member 12 of the suspension magnetic assembly 10 is in the power generation cavity. 301 moves inside to disturb the magnetic field lines and cause changes in magnetic flux.

[0139] It is worth mentioning that the top cover 31 and the bottom cover 32 of the housing 30 form a package for the hollow coil 20 accommodated in the power generation cavity 301, thereby making the hollow The coil 20 is not easily damaged by external force, thereby improving the reliability and durability of the self-resetting suspended magnetic generator 100 .

[0140] It should be pointed out that in the magnetic switching generator of the prior art, the mutual movement between the magnetic conductive plate of the magnet and the iron core of the coil will cause mechanical collision, resulting in a "slapping" mechanical impact noise, and now in the prior art, in order to improve the magnetic permeability between the magnetic permeable plate and the iron core, these components are usually made of alloy materials, such as iron-nickel alloy, which results in higher manufacturing costs. In particular, in the present invention, the self-resetting suspended magnetic generator 100 adopts a suspended magnetic structure, so that there is no gap between the top cover 31 and the bottom cover 32 of the housing 30 and each component. Mechanical collision and friction will not cause accelerated oxidation of the magnetically permeable material. Therefore, the housing 30 can be made of ordinary galvanized iron It is reduced by 70%, which greatly reduces the manufacturing cost of the self-resetting suspended magnetic generator 100. At the same time, the mechanical noise of the self-resetting suspended magnetic generator 100 is reduced compared with the generators of the prior art. In other words, the present invention The self-resetting suspended magnetic generator 100 provided does not have the mechanical noise that is as loud as that of the prior art, and also significantly reduces the cost and produces very obvious economic benefits.

[0141] In particular, the suspended magnetic component 10 moves axially relative to the hollow coil 20 along the suspended magnetic channel to disturb the magnetic field formed by the hollow coil 20 at the center position of the hollow coil 20. The displacement of the magnetic flux lines within the range of the magnetic flux lines of the hollow coil 20 is greater, which improves the power generation efficiency of the self-resetting suspended magnetic generator 100 and reduces the power generation efficiency of the self-resetting suspended magnetic generator 100 Compared with the existing pivoting motion power generation device, the power generation efficiency is increased by at least 20% to 35%, thereby improving the power generation efficiency of the self-resetting suspended magnetic generator 100 .

[0142] That is to say, the relative movement direction of the suspended magnetic assembly 10 and the hollow coil 20 is the axial movement along the suspended magnetic channel, which is different from the pivoting movement mode of the existing power generation device, and further The disturbance of the magnetic field lines by the suspended magnetic component 10 is increased, the change of the magnetic flux is increased, and the power generation efficiency of the self-resetting suspended magnetic generator 100 is improved.

[0143] It should be pointed out that the self-resetting suspended magnetic generator 100 disclosed in this aspect provides an efficient generator technical solution, and optionally in some embodiments, it is ultra-low for certain loads. In the application scenario of power-consuming radio frequency chips, on the premise of ensuring that the generated electric energy meets the needs, the top cover 31 and the bottom cover 32 of the housing 30 can be partially cut off as needed to achieve The need for leads or to meet the overall assembly needs, for example, opening additional holes on the top cover 31 and the bottom cover 32 , or partially cutting the sides or both sides of the top cover 31 and the bottom cover 32 resection.

[0144] Further, the top cover 31 includes a first magnetic wall 3101 and a second magnetic wall 3102 extending downwardly from the first magnetic wall 3101 perpendicular to the first magnetic wall 3101. The first magnetic wall 3101 The center is hollowed out to form the driving hole 311, and corresponding to the first magnetic wall 3101, it has an inward side facing the driving hole 311 and an outer side opposite to the inward side, and the second magnetic wall 3102 is formed from The outer side of the first magnetic wall 3101 extends downward, so that the power generation cavity 301 can be defined below the top cover 31 based on the morphological design of the top cover 31 , wherein the bottom cover 32 includes a The bottom magnetic wall 3201 and a side magnetic wall 3202 extending upwardly from the edge of the bottom magnetic wall 3201 perpendicularly to the bottom magnetic wall 3201, wherein the second magnetic wall 3102 of the top cover 31 and the bottom cover 32 The side magnetic walls 3202 are directly abutting or approaching each other to enhance the intensity of the magnetic flux lines covering the hollow coil 20 , which is beneficial to improving the power generation efficiency of the self-resetting suspended magnetic generator 100 .

[0145] It is worth mentioning that the second magnetic wall 3102 of the top cover 31 has the function of collecting magnetism, which can reduce the magnetic resistance between the N-S poles of the return member 12, that is, reduce The width of the open magnetic field between the N-S poles is increased, so that the magnetic field density between the N-S poles of the return member 12 is significantly enhanced to enhance the utilization of the magnetic field and thereby improve the power generation efficiency. If not If the second magnetic wall 3102 is provided, the efficiency of the self-resetting suspended magnetic generator 100 will decrease by more than 50%, and it will be unable to provide effective driving power and is not practical. It can be understood that the self-resetting suspended magnetic generator 100 disclosed in the present invention belongs to a micro-generator, and each component requires precise coordination. Therefore, the shape, contact relationship of each component, and the width of the magnetic gap will all Affects the efficiency of the self-resetting suspended magnetic generator 100.

[0146] In addition, setting the second magnetic wall 3102 can also make the self-returning suspended magnetic generator 100 suitable for being installed and fixed on a specific product, for example, providing holes or slots on the second magnetic wall 3102, The effect of stabilizing the self-resetting suspended magnetic generator 100 can be achieved by using the hook on the housing to engage the slot on the second magnetic wall 3102. It is also worth mentioning that the arrangement of the second magnetic wall 3102 also This can protect the hollow coil 20 from being easily damaged during transportation and installation of the self-resetting suspended magnetic generator 100 .

[0147] It is worth mentioning that in this embodiment of the present invention, the top cover 31 and the bottom cover 32 of the housing 30 have an upper and lower distributed structure. Based on achieving the same purpose, in some implementations For example, the casing 30 can also be designed as a left and right distributed casing structure. For example, the casing 30 is configured as two semicircles and joined left and right to form the casing 30, corresponding to the shells on the left and right sides. In the state of body synthesis, the left and right sides of the housing jointly define the power generation cavity 301, and the upper part of the corresponding left and right sides of the housing is the top cover 31, and the lower part is the bottom cover 32, resulting in the effect It is the same as the upper and lower distributed structure of the housing 30 in the example of the present invention, and is a deformed implementation structure of the housing 30, which is not limited by the present invention.

[0148] It is worth mentioning that the suspended magnetic assembly 10 is configured using the hollow channel 201 defined by the hollow coil 20 to make full use of the objective size of the selfresetting suspended magnetic generator 100. size, so that the overall size of the self-resetting suspended magnetic generator 100 can be set close to the size of the hollow coil 201. Intuitively, the size of the self-resetting suspended magnetic generator 100 is less than the size of a one-yuan coin, size, realizing the miniaturization and miniaturization of the self-resetting suspended magnetic generator 100.

[0149] In particular, wherein the suspended magnetic assembly 10 moves along the suspended magnetic channel in a driven state, and can self-reset along the suspended magnetic channel in a direction opposite to the direction when being driven, Therefore, it is possible to move back and forth in the suspended magnetic channel without the need to install large and complex pivoting motion components and reset components, thereby achieving miniaturization and miniaturization of the self-resetting suspended magnetic generator 100 .

[0150] It is worth mentioning that the suspended magnetic component 10 and the hollow coil 20 are independent of each other, and there is no need to set up additional connecting components. That is to say, the suspended magnetic component 10 is relative to the hollow coil 20. It is suspended and moves relative to the hollow coil 20 along the suspended magnetic channel in a suspended state, thereby simplifying the structural design of the self-resetting suspended magnetic generator 100 .

[0151] In other words, in which the suspended magnetic component 10 is suspended in the suspended magnetic channel, there is no need to set up complex pivoting motion components, reset components and connecting components. The structure of the self-resetting suspended magnetic generator 100 It is simple, has a high degree of component modularity, and reduces production difficulty and process accuracy requirements, which is beneficial to reducing the volume of the self-resetting suspended magnetic generator 100 and reducing the production of the selfresetting suspended magnetic generator 100. The manufacturing cost is reduced and the production yield rate of the self-resetting suspended magnetic generator 100 is improved.

[0152] Further, the movement stroke of the magnetic suspension assembly 10 is such that the return member 12 can maintain magnetic attraction with the top cover 31 and automatically reset after the force of the driving member 11 is removed, so that in The self-reset of the self-resetting suspended magnetic generator 100 can be realized without setting up a special reset device, thereby simplifying the structural design of the self-resetting suspended magnetic generator 100 and ensuring the self-resetting suspended magnetic generator 100 performance.

[0153] Further, with reference to FIGS. 5Aand 5B in detail, the return member 12 has a contact portion 121. Initially, the contact portion 121 of the return member 12 is under the action of magnetic attraction. A contact portion 312 is adsorbed and abutted on the top cover 31. The contact portion 312 is located on the first magnetic wall 3101 and surrounds the inward side of the first magnetic wall 3101. When the return member 12 is When implemented as a permanent magnet, a stable N-pole magnetic field is provided to the top cover 31 of the housing 3, and the diffusion conduction of the first magnetic wall 3101 and the second magnetic wall 3102 of the upper cover 31 is under the action of magnetism, the magnetic flux lines are uniformly conducted to the bottom cover 32 , and the side magnetic walls 3202 and the bottom magnetic wall 3201 of the bottom cover 32 conduct the magnetic flux lines to S of the return member 12 pole, thereby forming a closed stable magnetic field that completely covers the hollow coil 20 . Based on the structure of the self-resetting suspended magnetic generator 100, the self-resetting suspended magnetic generator 100 has a high utilization rate of the magnetic field, so that the volume of the selfresetting suspended magnetic generator 100 can be as large as possible. The ground is made smaller, or the generator can generate higher electrical power under the same volume than the generator in the prior art, and when the return member The return member 12 moves forward at a relatively high speed, but because the return member 12 does not hit other components, it does not produce the huge "pop" noise in the prior art.

[0154] In particular, the return member 12 also has a driven portion 122, which is the portion of the return member 12 that is in contact with or close to the driving member 11, wherein the driven portion 122 is the portion of the return member 12 that is in contact with or close to the driving member 11. When the end 111 of the driving member 11 close to the return member 12 is in contact with the driven portion 122 of the return member 12, since the driving member 11 and the return member 12 have relatively small Therefore, when the driving member 11 moves, it can have the beneficial effect of stabilizing and balancing the return member 12. The return member 12 moves forward or forward due to the force exerted by the driving member 11. There will be no shaking during the reset process. At the same time, since the driving member 11 and the return member 12 have a large relative range, when the return member 12 suddenly breaks away from the contact portion 312 of the top cover 31 in the initial position, the entire abutting portion 121 of the return member 12 and the contact portion 312 are separated instantaneously and synchronously on a microscopic level, which plays a vital role in generating intensity of electrical energy because the abutting portion 121 To be distributed around the driven portion 122 , when the return member 12 is driven by the driving member 11 , if the contact portion 121 of the return member 12 contacts the top cover 31 If one side of the unbalanced portion 312 is detached first and the other side is detached later, the above-mentioned effect of instantaneous synchronous separation cannot be achieved, and the instantaneous change of the magnetic field will be relatively slow, resulting in a significant reduction in the intensity of the generated electric energy.

[0155] It is worth mentioning that initially, based on the magnetic attraction between the return member 12 and the top cover 31, the contact portion 121 of the return member 12 and the top cover 31 The contact portion 312 attracts and contacts. At this time, the top cover 31 is in a saturated magnetic field, and the hollow coil 20 is in a static saturated magnetic field. When the driving member 11 is driven by an external force, the driving member 11 pushes the return member 12 moves, and the return member 12 suddenly breaks away from the adsorption contact with the contact portion 312 on the top cover 31 from the initial state, and the top cover 31 instantly changes from a saturated magnetic field to an unsaturated magnetic field, Therefore, the strength of the magnetic field lines changes, and based on the change in the strength of the magnetic field, the hollow coil 20 is disturbed by the dynamically changing magnetic field, causing the density of the magnetic field lines in the hollow coil 20 to change, thereby causing the hollow coil 20 generates induced electric energy.

[0156] In particular, since the area of the side of the return member 12 facing the contact portion 312 is larger than the relative area of the side of the return member 12 and the top cover 31, and the return member The contact portion 121 of the position member 12 and the contact portion 312 of the top cover 31 are arranged facing each other. The magnetic attraction between the contact portion 121 of the return member 12 and the top cover 31 is always Greater than the magnetic attraction between other parts of the return member 12 and the top cover 31 , that is to say, the contact portion 121 of the return member 12 and the top cover 31 have a strong magnetic interaction force. , even if the distance between the two exceeds 2 mm, they can still be automatically adsorbed together again under the rotation of external contact, which solves the technical defect of the existing technology that cannot be reliably reset when the distance exceeds 0.5 mm, and in some cases In embodiments or application scenarios, even if the self-resetting suspended magnetic generator 100 is equipped with a housing button, the self-resetting suspended magnetic generator 100 can still push the housing button to reset.

[0157] It is worth mentioning that in this embodiment of the present invention, the bottom cover 32 has a bottom opening 321 connected to the power generation cavity 301, and the bottom opening 321 is preferably located the projection ofthe driving hole 311 toward the bottom cover 31 is located in the bottom opening 321. In other words, the bottom opening 321 is connected to the hollow channel 201 defined by the hollow coil 20 and is larger than the bottom opening 321. The driving hole 311 is provided to ensure that the return member 12 and the top cover 31 maintain magnetic attraction.

[0158] In particular, the aperture ofthe bottom opening 321 is largerthan the outer diameter of the return member 12; in this way, it can be ensured that the strong magnetic field line of the magnetized surface of the return member 12 is in contact with the bottom opening 321. The interaction is small, and the return member 12 will not be adsorbed by the bottom cover 32 during movement. When the return member 12 moves to the bottom opening 321, it can also pass through the bottom opening 321, thereby forming a first magnetic gap between the return member 12 and the bottom opening 321.302, and it is precisely because ofthe existence ofthe first magnetic gap 302 that the magnetic induction density in the hollow coil 20 is greatly enhanced; the return member 12 is further pushed until the return member 12 is the contact portion 121 is close to the bottom cover 32 . At this time, the magnetic field will the original N pole contacts the driving hole 311 and instantly changes to the N pole interacting with the bottom cover 32. The direction of the magnetic field passing through the hollow coil 20 is reversed. This is a complete change in the magnetic pole. , causing the magnetic density in the hollow coil 20 to instantly reverse, thereby inducing stronger energy.

[0159] Particularly, in the prior art, when the magnet moves in the air-core coil, the magnetic field lines will only vertically cut the coil with fixed magnetic poles and will not produce the special effect of instantaneous reversal of the magnetic poles. When there is no rotating magnet, the magnetic poles of the magnet will not reverse; and the existing technology requires the magnet to repeatedly move back and forth in the air-core coil for a period of time and accumulate energy for a period of time before it can be utilized, and the technical solution disclosed in the present invention is for a single The power generation energy generated by this operation can be used immediately; for example, when the self-resetting suspended magnetic generator 100 supplies power to a wireless switch, the transmitting circuit can immediately send out a signal at the moment of pressing, without the need for the current The technology requires repeated operations and waiting for sufficient energy to be accumulated before use; therefore, the power generated by the self-resetting suspended magnetic generator 100 will be at least doubled or even dozens of times higher than that of the existing technology.

[0160] When the return member 12 is driven to the set position by the driving member 11, a first magnetic gap 302 exists between the return member 12 and the bottom magnetic wall 3201 of the bottom cover 32, so that It is ensured that the return member 12 will not be adsorbed on the bottom cover 32 and unable to automatically reset, so that when the corresponding driving force is contacted, the return member 12 can self-return to the initial position. The first magnetic gap 302 is set to be less than 4 mm, which is beneficial to ensuring the power generation efficiency of the self-resetting suspended magnetic generator 100 .

[0161] It can be understood that when the movement stroke of the magnetic suspension assembly 10 is such that the return member 12 can maintain magnetic attraction with the top cover 31, the bottom opening 321 can also be set smaller than the required size. The driving hole 311 is described.

[0162] As shown in Figure 8B, since the magnetizing surface of the return member 12 has the contact portion 121, the contact portion 121 and the drive tube 312 are arranged facing each other, so there is a pole between the two. Strong magnetic suction force, with the prerequisite for longdistance magnetic suction reset. The side surface of the return member 12 is not a magnetized surface, and there is a gap 302 between the return member 12 and the bottom cover 32. The magnetic attraction force is weak, so the return member 12 can pass through the holes on the bottom cover 32. The bottom opening 321 will not be adsorbed by the bottom cover 32, so that while the stroke of the return member 12 can be further extended to enhance the power generation, the return member 12 can also have long stroke and powerful automatic reset capability.

[0163] It should be pointed out in particular that when the return member 12 is driven to the end position by the driving member 11, if the pressed driving state is maintained at this time, the return member 12 will be driven by the driving member 11. It can float and rest at the end position by being pressed.

[0164] It should be pointed out in particular that the bottom opening 321 is not used for force driving. It has the following beneficial effects: first, the return member 12 is avoided so that the return member 12 can pass through it. The bottom opening 321 has a larger stroke to generate greater power generation; secondly, the bottom opening 321 maintains the function of gathering magnetic fields, so that the N-S magnetic field of the return member 12 is the top cover 31 and the bottom cover 32 are closed and magnetically conductive and have extremely small magnetic resistance to improve power generation efficiency; thirdly, keep an appropriate distance between the return member 12 and the bottom opening 321 a small distance to form a state in which the magnetic attraction force between the driving hole 311 and the return member 12 is greater than the magnetic attraction force between the bottom opening 321 and the return member 12 to ensure that the automatic reset can be successful. Fourth, the return member 12 will not hit the bottom cover 32 when moving at high speed, so that no impact noise will be generated. As is known to all, magnets are fragile components, which will cause them to break when struck repeatedly with high force. Therefore, providing the bottom opening 321 on the bottom cover 32 has significant beneficial effects.

[0165] In some embodiments, the bottom opening 321 may not be provided, but the return member 12 must be kept at an appropriate distance from the bottom cover 32 to ensure that the return member 12 It can be automatically reset, and the present invention does not limit this.

[0166] It is worth mentioning that the phenomenon of electromagnetic induction has been discovered for more than 100 years. Those skilled in the art know cutting a closed coil will generate an induced electromotive force in the coil, but this is only the basis of theory. Howto breakthrough the limitations of existing technology and make the micro generator more labor-saving and smaller in size, but still able to generate high power? It is the purpose of continuous research and development by technicians in this field for many years that the electric energy drives the transmitting circuit to work, has practical performance and achieves good economic benefits.

[0167] It is worth mentioning that, based on the purpose of ensuring the structural stability of the self-resetting suspended magnetic generator 100, the self-resetting suspended magnetic generator 100 also includes a coil bracket 40, wherein the coil bracket 40 is used to fix the shape of the hollow coil 20 and prevent the hollow coil 20 from being directly impacted by the suspended magnetic assembly 10. Specifically, the shape of the coil bracket 40 matches the shape of the hollow coil 20. , including a bracket wall surrounding the hollow channel 201 of the hollow coil 20 and a bracket seat 42 matching at least one side of the hollow coil 20, so that the hollow coil 20 is installed on the coil bracket 40 state, the inner wall of the hollow coil 20 is surrounded by the bracket wall of the coil bracket 40 to form a pipe 41 , and at least one side of the hollow coil 20 is surrounded by the bracket seat 42 of the coil bracket 40 The support is in the form of fixing the hollow coil 20, and when the suspended magnetic assembly 10 moves along the hollow channel 201 of the hollow coil 20, that is, when moving along the pipe 41, it is located at the bracket wall between the suspended magnetic component 10 and the hollow coil 20 forms a protection for the hollow coil 20 to prevent the suspended magnetic component 10 from hitting the hollow coil 20 to extend the self-resetting suspended magnetic component. The service life of the type generator is 100. Moreover, the pipe 41 formed by the bracket wall makes the suspended magnetic assembly 10 smoother and more stable when the hollow channel 201 makes axial piston movement relative to the hollow coil 20, and also protects the hollow The inner side of the coil 20 is not easily damaged. In particular, due to the provision of the pipe 401, when the return member 12 is thin, the return member 12 will not roll over due to the limitations of the side walls of the pipe 41. Phenomenon. Furthermore, in addition to supporting the hollow coil 20, the bracket seat 42 of the coil bracket 40 also plays a role in engaging the bottom cover 32. In other words, the coil bracket 40 does not only have the function of supporting and fixing. The hollow coil 20 also plays a role in firmly connecting multiple components of the self-resetting suspended magnetic generator 100, thereby helping to reduce the assembly difficulty of the self-resetting suspended magnetic generator 100. This is beneficial to improving the production efficiency of the self-resetting suspended magnetic generator 100 .

[0168] Particularly, in some embodiments, the coil support 40 may be configured to close the opening of the hollow channel 201 near the bottom cover 32 to form a movement limit for the suspended magnetic assembly 10. , to ensure that the return member 12 and the top cover 31 maintain magnetic attraction, so that the magnetic suspension assembly 10 moves in a suspended manner in the magnetic suspension channel.

[0169] Further, in order to further improve the power generation efficiency and structural stability of the self-resetting suspended magnetic generator 100, the present invention further optimizes the structure of the self-resetting suspended magnetic generator 100. Specifically, refer to 6 and 8B of the accompanying drawings, the self-returning suspended magnetic generator 100 according to a preferred embodiment of the present invention is schematically illustrated. Specifically, in the preferred embodiment, the top cover 31 further includes a self-returning hole from the driving hole. A driving tube 312 extends from the peripheral edge of 311 toward the direction of the bottom cover 32. One end of the driving tube 312 where the driving hole 311 is located is the top of the driving tube 312, and the other end of the driving tube 312 is One end is the bottom end of the driving tube 312, wherein the driving member 11 extends into the driving tube 312 from the top end of the driving tube 312, and drives all parts of the driving tube 312 in a force-driven state. The return member 12 at the bottom end moves in a direction away from the top cover 31. When the force of the driving member 11 is removed, the return member 12 is magnetically attracted to the top cover 31. They are attracted to each other and move toward the top cover 31 , thereby being abutted against the bottom end of the drive tube 312 , so as to guide and limit the movement of the suspension magnetic assembly 10 based on the drive tube 312 . The structural stability of the selfresetting suspended magnetic generator 100 is ensured.

[0170] Referring to Figure 7 in further detail, the drive tube 312 is located in the suspended magnetic channel, thereby forming a physical medium guide for the magnetic circuit in the suspended magnetic channel, thereby enhancing the self-resetting suspended magnetic generator. That is to say, in a state where the drive tube 312 is not provided, the magnetic circuit of the self-resetting suspended magnetic generator 100 is formed under the action of two poles without corresponding media guidance. In other words, the drive tube 312 The setting kills two birds with one stone, while limiting and guiding the movement of the magnetic suspension assembly 10, it is also equivalent to arranging a medium in the magnetic suspension channel to guide the magnetic circuit, which not only ensures the self-returning magnetic suspension type The structural stability of the generator 100 further improves the power generation efficiency of the selfresetting suspended magnetic generator 100 .

[0171] It is worth mentioning that the drive tube 312 penetrates the hollow coil 20 and is located in the suspended magnetic channel, so the drive tube 312 increases the inductance of the hollow coil 20 to further enhance The value of the magnetic flux BL between the magnetic field and the hollow coil 20 causes the magnetic intensity of the magnetic field acting on the hollow coil 20 to significantly increase, thereby improving the power generation efficiency of the self-resetting suspended magnetic generator 100, so that the power generation efficiency of the self-resetting suspended magnetic generator 100 can be improved compared to the existing generator after being miniaturized, and has stronger power generation energy after being miniaturized. Therefore, the drive 312 It has the multiple benefits of increasing the magnetic field intensity to enhance power generation efficiency, guiding and positioning the magnetic circuit to form a physical medium, limiting and guiding the movement of the suspended magnetic assembly 10 to form a physical medium, and attracting and resetting the suspended magnetic assembly 10.

[0172] In particular, compared with the technical solution of Figure 4, this embodiment not only adds a drive tube 312, but in fact this embodiment is an overall structure. Compared with the solution of Figure 4, The efficiency can be improved by more than 80%; the drive tube 312 is inserted into the hollow coil 20, which not only plays a role in supporting and stabilizing the hollow coil 20, but also makes the magnetic field intensity passing through the hollow coil 20 high. The amplitude is improved. Compared with the existing technology where only the magnet passes through the hollow coil 20, the utilization rate of the magnetic field is higher; if only the magnet itself passes through the hollow coil 20 without the driving tube 312, Then, the N-S pole magnetic field lines will directly cause a magnetic short circuit at the upper and lower ends of the magnet along the sides of the magnet, so the magnetic field lines passing through the hollow coil 20 will be reduced. The drive tube 312 is set This is an important means to significantly improve the power generation efficiency of this embodiment. After actual measurement, this embodiment can generate 340 uJ of energy when the driving member 11 drives the return member to move 2.3 mm. That is, when the dummy load is 200 ohms, this embodiment is voltage stabilized. Finally, it can provide a 2V power supply voltage to the dummy load, and the duration can be as long as 17mS, meeting the requirements of the Bluetooth SMS protocol to send more than 20 frames. And if the energy generated during the automatic reset of this embodiment is reused, various low-power wireless communication devices can be driven during a press-release cycle. Therefore, this embodiment has significant practical value and can be widely used in various passive products.

[0173] It is worth mentioning that in order to ensure that the return member 12 remains stable during the axial movement, so that the return member 12 will not deviate during the movement, therefore, in In some embodiments, a pipe 41 with a smooth inner wall is allowed to be provided in the suspended magnetic channel 201, and a gap of greater than 0.02 mm is maintained between the pipe 41 and the return member to ensure that the return member 12 can slide freely in the axial direction and can be kept centered by the pipe 41; initially, the return member 12 and the drive pipe 312 are magnetically adsorbed freely without the help of other mechanical components. Together, when an external force is applied to the return member 12 and the external force is greater than the magnetic attraction force between the return member 12 and the drive tube 312 , the return member 12 and the drive tube 312 instantly Separation; wherein the return member 12 is ejected by an external force at a speed of about 0.05m / S to freely move rapidly in the pipe 41 in a direction away from the drive tube 312, thereby causing the surrounding Induced electric energy is generated in the hollow coil 20 around the tube 312; when the return member 12 moves rapidly, it is guided by the pipe 41. Since the return member 12 moves at a high speed, the pipe 41 the inner side of 41 is relatively smooth, so the return member 12 can move freely at high speed with a smaller own mass without being bound by mechanical parts to generate as strong an induced energy as possible, thus improving the overall the power generation efficiency of the self-resetting suspended magnetic generator 100 is described.

[0174] It can be understood that the hollow coil 20 can be arranged around the driving tube 312, or can be arranged Arranged around the return member 12 , this depends on the winding thickness of the hollow coil 20 and can be set according to the specific structure of the hollow coil 20 .

[0175] It can be understood that the suspended magnetic channel is a space for the movement of the return member 12, and the arrangement of the pipe 41 will make the movement of the return member 12 smoother and more stable. In some embodiments , when the side walls of the suspended magnetic channel are made smooth enough or wear-resistant enough, the pipe does not need to be provided separately. In this way, only the inner wall of the hollow coil 20 can also serve as the pipe 41 . The pipe 41 can also be formed by superimposing a plurality of parts with holes in the middle. According to the disclosure of the present invention, as long as the movement of the return member 12 can be made smoother and more stable, the specific form and material of the pipe 41 are not required by the present invention, limit.

[0176] In particular, one end of the pipe 41 is close to or abutting the drive tube 312, and the other end extends in a direction away from the drive tube 312 to meet the needs of the movement stroke of the return member 12; wherein , when a housing is present, one end of the pipe 41 away from the driving tube 312 is disposed close to or abutting the housing.

[0177] It is worth mentioning that the movement of the return member 12 is similar to that of a piston. In orderto reduce the damping effect of air on the movement of the return member 12, one end of the pipe 41 is away from the drive tube 312. Is configured to be open or have a small hole to prevent the air from being compressed and creating a damping characteristic.

[0178] In particular, the pipe 41 can be individually configured in an O-shape or a C-shape, for example, wound with a high-strength 0.15 mm thick Teflon film sheet, or integrally formed with the coil support 40 , the present invention does not limit this.

[0179] It is worth mentioning that, different from the design of magnets in the prior art, the return member 12 of the present invention belongs to a free suspended magnetic structure without a fixed connection, that is, the return member 12 is not When tightening with various fastening components such as screws, rivets, and fixing grooves, the return member 12 can be adsorbed and fixed by utilizing the magnetic force between the return member 12 and the top cover 31 , thereby moving in the suspended magnetic channel in a free manner, so that a faster movement speed can be obtained with a smaller mass, so that the self-resetting suspended magnetic generator 100 generates higher induced energy.

[0180] In particular, referring to Figures 8A and 8B, the bottom end of the drive tube 312 has a bottom end surface 3121. Initially, the bottom end surface 3121 is magnetically attracted by the return member 12, and the bottom end surface 3121 and the contact portion 121 of the return member 12 are attracted together under the action of magnetic force, so that even when the return member 12 is driven away from the drive tube 312, due to the return member 12 The contact portion 121 of 12 and the bottom end surface 3121 are arranged facing each other, so they have a large relative area and generate strong magnetic interaction. Even if the distance between the two exceeds 2 mm, they can still In the case of external contact, it is automatically adsorbed again to realize the automatic reset of the return member 12, which solves the technical defect of the existing technology that cannot be reliably reset when the distance exceeds 0.5 mm, making the self-returning suspended magnetic generator The electrical appliance 100 has strong product manufacturing advantages when used as a passive wireless switch. It can reduce the number of parts and costs, has a simpler structure, and significantly improves economic benefits.

[0181] It is worth mentioning that the driving tube 312 extends in the direction of the bottom cover 32, and divides the power generation chamber 301 into a driving chamber 303 and an accommodation chamber 304. The chamber 303 accommodates the suspended magnetic component 10 and allows the suspended magnetic component 10 to move in the driving chamber 303. The accommodating chamber 304 accommodates the hollow coil 20. The driving chamber 303 and the accommodation chamber 304 has different functions and partitions, which are relatively independent of each other.

[0182] Preferably, the length of the drive tube 312 is set to be greater than or equal to 0.1mm and less than or equal to 15mm, so as to ensure the self-resetting suspended magnetic generator while satisfying the driving stroke of the suspended magnetic assembly 10.100mm thick and light.

[0183] Further, when an external force drives the driving member 11, the driving member 11 will transmit the force to the return member 12, because the outer peripheral wall of the driving member 11 and the inner wall of the driving hole 311 The gap between them is set very small, and is preferably set to less than 0.2mm in the present invention. Therefore, when the driving member 11 makes It can be limited by the driving hole 311 and remain stable, and will not fall over during the movement. Furthermore, when the driving member 11 drives the return member 12, the return member 12 is moved by the driving member 11. The push will also remain stable, that is to say, the driving member 11 has the function of maintaining the stable movement of the return member 12 .

[0184] In particular, when the return member 12 is driven by the driving member 11, the return member 12 is forced to move in a direction away from the drive tube 312. At this time, the return member 12 is separated from the drive tube 312, wherein in the state where the return member 12 is separated from the drive tube 312, the return member 12 and the bottom end of the drive tube 312 maintain a second magnetic gap 305 , the magnetic field between the return member 12 and the driving tube 312 changes from a saturated magnetic field to a non-saturated magnetic field. Furthermore, due to the driving of the driving member 11, the return member 12 will move to be in contact with the bottom magnetic wall. 3201 is close to the position, the first magnetic gap 302 exists between the return member 12 and the bottom magnetic wall 3201. At this time, the magnetic field intensity between the return member 12 and the bottom magnetic wall 3201 is greater than that of the return member 12 and the bottom magnetic wall 3201. Part 12 is significantly raised when in the initial position. That is to say, the movement of the return member 12 causes a change in the magnetic density in the stable magnetic field in the initial state, thereby generating induced electric energy in the hollow coil 20 , where the movement speed of the return member 12 The faster, the higher the induced voltage generated in the hollow coil 20. In order to ensure that the self-resetting suspended magnetic generator 100 can generate a voltage greater than 10V each time it is operated to meet the needs of driving the corresponding load, so The movement speed of the return member 12 is preferably set to be greaterthan 0.1m / s.

[0185] It is worth mentioning that the abutment portion 121 of the return member 12 is arranged directly opposite the bottom end surface 3121 of the drive tube 312, so there is a large active area between the two., which can produce a strong magnetic interaction. The magnetic attraction force in the second magnetic gap 305 is greaterthan the magnetic attraction force in the first magnetic gap 302. Therefore, even if the width of the second magnetic gap 305 exceeds 2 mm, The return member 12 can also be automatically adsorbed on the drive tube 312 when the driving force of the drive member 11 is cancelled.

[0186] In particular, the top cover 31 includes the drive tube 312, and the drive tube 312 constitutes a third magnetic wall 3103 of the top cover 31, wherein the third magnetic wall 3103 is formed from the first magnetic wall. The inward side of 3101 extends downward perpendicularly to the first magnetic wall 3101. Corresponding to the cross-sectional structure of the self-resetting suspended magnetic generator 100 in Figures 8A and 8B, the third magnetic wall 3103, the first The magnetic wall 3101, the second magnetic wall 3102, the side magnetic wall 3202 and the bottom magnetic wall 3201 form two symmetrical C-shaped enclosures in the self-returning suspended magnetic generator 100, wherein the gap remaining between the first magnetic wall 3101 and the bottom magnetic wall 3201 is small, and the width of the gap is only the thickness of the return member 12 plus the sum of the second magnetic gap 305 and the first magnetic gap 302. Preferably, the minimum gap between the first magnetic wall 3101 and the bottom magnetic wall 3201 is set to no more than 5 mm, so that the magnetic induction intensity can be maintained high. Furthermore, based on the design of various parameters, the self-resetting suspended magnetic generator 100 has high power generation efficiency and good driving feel despite its small size. It is preferable that the second magnetic gap 305 is set to be larger than Equal to 0.4 mm, the first magnetic gap 302 is set to be greaterthan 0.1 mm.

[0187] Further, in some embodiments of the present invention, the bottom cover 32 of the housing 30 and the coil support 40 may not be provided. Specifically, refer to Figure 9 of the accompanying drawings of the present invention. Referring to Figure 11B, the self-resetting suspended magnetic generator 100 of another embodiment of the present invention is schematically shown. Compared with the self-returning suspended magnetic generator 100 of the preferred embodiment of the present invention, the self-returning suspended magnetic generator 100 of the present invention is the self-resetting suspended magnetic generator 100 of another embodiment has a simpler structure. The self-resetting suspended magnetic generator 100 includes the upper cover 31, the hollow coil 20, the driving member 11 and the return member 12, the upper cover 31, the hollow coil 20, the driving member 11 and the return member 12 are stacked concentrically and axially, wherein the upper cover 31 includes the drive hole 311 and The drive tube 312, the drive tube 312 and the upper cover 31 can be manufactured separately and then assembled, or can be integrally formed, and the present invention is not limited to this.

[0188] In particular, the drive tube 312 constitutes the 3103, corresponding to the cross-sectional structure of the self-resetting suspended magnetic generator 100 in Figures 11A and 11B, the third magnetic wall 3103, the first magnetic wall 3101, and the second magnetic wall 3102 are in the self-resetting The suspended magnetic generator 100 forms two symmetrical inverted C-shaped enclosures to accommodate the hollow coil 20 . The second magnetic wall 3102 can diffuse the magnetic field to the outside of the hollow coil 20, and can achieve the effect of protecting the hollow coil 20.

[0189] It is worth mentioning that this embodiment can provide an extremely strong static N-S penetrating magnetic field for the hollow coil 20 in the initial state, instead of only providing a single N-pole or S-pole unipolar magnetic field.; That is to say, in the initial state, the N pole and S pole of the return member 12 simultaneously provide a penetrating strong magnetic field for the hollow coil 20 through the housing 30 to increase the power generation efficiency and reduce the Magnetic resistance; as shown in Figure 7, Figure 8A, and Figure 8B, in the static state, the magnetized surface (N pole of the magnet) of the return member 12 is in contact with the drive tube 312, and the N pole of the return member 12 is in contact with the driving tube 312. The pole magnetic induction lines are conducted to The S pole of the return member 12 forms a closed-loop magnetic conduction, so that the static magnetic field obtained by the hollow coil 20 at the beginning is very strong; although there is the first magnetic field in this closed-loop magnetic conduction loop, However, since the first magnetic gap 302 is relatively narrow and the magnetic resistance is small, the entire closed-loop magnetic conduction loop still has an extremely strong initial magnetic field, forming a saturated magnetic field.

[0190] As shown in Figure 8B, when the driving member 11 drives the return member 12 to separate from the drive tube 312, the intensity of the saturated magnetic field weakens rapidly. The driving tube 312 is getting further and further away. When the abutting portion 121 of the return member 12 is substantially flush with the bottom magnetic wall 3201, the bottom magnetic wall 3201 is closer to the S pole of the return member 12 from its original position. , becomes close to the N pole, therefore, the magnetic field intensity in the hollow coil 20 changes drastically, so that this embodiment can efficiently generate an induction pulse output. It can be understood that when this embodiment automatically resets, an electrical pulse will be output again.

[0191] In particular, in this embodiment, the N-S penetrating magnetic field has a lower magnetic resistance than a unipolar magnetic field that only uses N pole or S pole, and the energy generated by the power generation device increases several times. It can better reflect the invention goals of high efficiency and small volume of the present invention.

[0192] It is worth mentioning that in this other embodiment of the present invention, the hollow coil 20 is surrounded by the outer periphery of the driving tube 312, so that the driving tube 312 forms a barrier to the hollow coil 20. Fixing and limiting, in some embodiments, the hollow coil 20 is allowed to be thinned to form a thickness equal to the length of the drive tube 312, so that the hollow coil 20 is only The ring is placed around the outer periphery of the driving tube 312 , and a gap is provided between the inner side of the hollow coil 12 and the outer side of the return member 12 , so that the return member 12 is driven by the driving member 11 when moving in the hollow channel 201.

[0193] Initially, the return member 12 and the bottom end surface 3121 of the drive tube 312 are magnetically attracted, and the bottom end surface 3121 of the drive tube 312 is in contact with the return member 12. The parts 121 are tightly attracted together under the action of magnetic force. At this time, the hollow coil 20 is in a static saturated magnetic field; when the driving part 11 drives the return part 12, the return part 12 moves toward Moving away from the driving tube 312, at this time, the hollow coil 20 is converted from a static saturated magnetic field environment to a disturbed magnetic field environment, that is, the hollow coil 20 is disturbed by the dynamically changing magnetic field, so the hollow coil 20 generates Induced electromotive force. Since the contact portion 121 of the magnetic surface of the return member 12 is arranged directly opposite to the bottom end surface 3121 of the drive tube 312 , the return member 12 is located on the side where the contact portion 121 is located. The magnetic force is always greater than the magnetic force on the peripheral side of the return member 12 , so there is a large area between the return member 12 and the drive tube 20 to produce a strong magnetic interaction, even if the return member 12 The distance between the drive tube 20 and the drive tube 20 is more than 2 mm and can still be automatically magnetically adsorbed together again when the external force is removed. The drive tube 312 corresponding to the second embodiment state, in which the bottom end surface 3121 of the driving tube 312 is annularly adsorbed on the abutting portion 121 of the return member 12 , and the middle part of the driving tube 312 is hollow and is suitable for accommodating the driving Part 11 improves the power generation efficiency of the self-returning suspended magnetic generator 100 and makes the pressing feel soft. Optionally, in some embodiments, the bottom end surface 3121 of the drive tube 312 can also be adsorbed on the abutment portion 121 of the return member 12 in a C-shape or U-shape.

[0194] It is worth mentioning that in the present invention, the center of the return member 12 is directly opposite the center of the drive hole 311, that is, the center position of the return member 12 is directly opposite to the drive hole 311. The center position of the driving member 11 is concentrically arranged, and the center of the driving member 11 is also directly opposite to the center of the return member 12. The driving member 11 extends into the driving pipe 312 from the top end of the driving pipe 312, And in a force driven state, the return member 12 located at the bottom end of the drive tube 312 is driven to drive the return member 12 to move in a direction away from the top cover 31 , wherein the drive member 11 When the driving force is removed, the return member 12 attracts each other to the top cover 31 under the action of magnetic attraction and returns to the direction of the top cover 31 , thereby abutting against the bottom end of the drive tube 312 again. Returning to the initial position, the bottom end surface 3121 of the drive tube 312 and the contact portion 121 of the return member 12 are attracted together again under the action of magnetic force.

[0195] Preferably, the movement stroke of the return member 12 in the magnetic suspension channel is greater than or equal to 0.5mm and less than or equal to 6mm, that is, in the state where the return member 12 is driven, the return member 12 The distance from the bottom end surface 3121 of the drive tube 312 is in the range of 0.5mm-6mm, thereby ensuring both the power generation capacity of the self-resetting suspended magnetic generator 100 and the self-resetting suspended magnetic generator. The miniature, thin and light design of the generator 100. Specifically, when the movement stroke of the return member 12 is less than 0.5 mm, the induction energy that the self-returning suspended magnetic generator 100 can generate is low, and when the movement stroke of the return member 12 is too long, this will result in the thickness and volume of the self-resetting suspended magnetic generator 100 being too large.

[0196] It is worth mentioning that preferably, when the return member 12 is driven, the side of the return member 12 facing away from the driving hole 311 will protrude from the side of the hollow coil 20. One side of the driving hole 311 ensures the power generation efficiency of the self-returning suspended magnetic generator 100 based on sufficient movement stroke.

[0197] Preferably, the magnet / magnetic conductive volume of the return member 12 is set to be greater than 32 cubic millimeters, thereby ensuring that the self-resetting suspended magnetic generator 100 has sufficient magnetic field density.

[0198] Particularly, in the present invention, the size of the return member 12 is as large as the bottom surface area of the drive tube 312, thereby ensuring the stability of the return member 12 during movement and reducing the return. There may be shaking when the position piece 12 is stressed.

[0199] It is worth mentioning that in the present invention, the number of turns of the hollow coil 20 is set to be greater than 450 turns and less than 1100 turns, so as to take into account the power generation output efficiency of the hollow coil 20 and at the same time take into account the automatic The size of the suspended magnetic generator 100 is reset. Specifically, the present invention is different from the coil winding method of the prior art. Since the self-returning suspended magnetic generator 100 has the superimposed thickness of multiple components, the movement of the return member 12 must also be reserved. Space, therefore the longitudinal thickness of the hollow coil 20 is limited. The only way to improve the output efficiency of the hollow coil 20 is to increase the number of turns in the diameter direction of the hollow coil 20. However, too many turns will lead to the failure of each layer of coils. The length of the wire will increase, causing the resistance to increase. Therefore, the number of turns of the hollow coil 20 is set to be greater than 450 turns and less than 1100 turns, taking into account both output efficiency and miniaturization design.

[0200] In particular, when the self-returning suspended magnetic generator 100 is installed in the corresponding housing, a safety distance of at least 0.1 mm is maintained between the return member 12 and the corresponding housing, thereby ensuring The return member 12 is safe during movement and will not be broken due to tens of thousands of movements.

[0201] It is worth mentioning that, on the premise of ensuring that the power generation of the selfresetting suspended magnetic generator 100 can meet the use needs of the corresponding load, the top cover 31 can also be partially the second magnetic wall 3102 of the cover 31 may not be provided, and the present invention does not limit this. Similarly, on the premise of ensuring that the power generation of the self-resetting suspended magnetic generator 100 can meet the usage needs of the corresponding load, the drive tube 312 can also be designed with part cut off, such as part of the side surface of the drive tube 312 The longitudinal section cut off corresponding to the drive tube 312 changes from a complete closed figure to a figure with an opening.

[0202] In particular, at least one of the driving member 11 and the return member 12 of the suspended magnetic assembly 10 is a permanent magnet to satisfy the disturbance and realization of the magnetic induction lines of the hollow coil 20 For the reset of the return member 12, with specific reference to FIGS. 12 to 14, the optional material arrangement methods of the magnetic suspension assembly 10 are respectively illustrated.

[0203] Corresponding to Figure 12, wherein the driving member 11 is a permanent magnet, and the return member 12 is a magnetic conductor to conduct the magnetism of the driving member 11, and ensure that the return member 12 and the top The magnetic attraction between the covers 31, in which the driving member 11 is a permanent magnet, and the movement of the driving member 11 in the suspended magnetic channel forms a change in the magnetic flux, which is conducive to improving the automatic movement based on the relative movement of a large area. The power generation efficiency of the suspended magnetic generator 100 is reset.

[0204] Corresponding to Figure 13, preferably, the return member 12 is a permanent magnet, and the driving member 11 abuts the return member 12 to drive the return member 12, wherein the driving member 11 is a non-magnetic conductive body, wherein for the purpose of reducing the friction between the driving member 11 and the housing 30, the driving member 11 is preferably made of self-lubricating nylon material, and the return member 12 is in contact with the top cover 31 is suspended in the magnetic suspension channel due to the magnetic attraction.

[0205] Corresponding to Figure 14, wherein the return member 12 and the driving member 11 are both permanent magnets, the movement of the suspended magnetic component 10 in the suspended magnetic channel forms a change in magnetic flux, which is conducive to large-area The relative movement improves the power generation efficiency of the self-resetting suspended magnetic generator 100.

[0206] Optionally, in some embodiments, the driving member 11 and the return member 12 can also be provided integrally to improve the modular integrity of the components of the self-resetting suspended magnetic generator 100. degree.

[0207] Preferably, in the self-resetting suspended magnetic generator 100 disclosed in the present invention, the hollow coil 20 is arranged in an annular shape. Referring to Figure 15, the annular hollow coil 20 in each direction the magnetic flux lines are uniform, so when the suspended magnetic component 10 moves relative to the hollow coil 20, the disturbance to the magnetic flux lines in all directions is more uniform, corresponding to the power generation of the self-resetting suspended magnetic generator 100. The degree of uniformity of the electricity generated during the process is improved, that is, the electricity generated by the same displacement in the same time period tends to be consistent, ensuring the power generation stability of the self-resetting suspended magnetic generator 100.

[0208] In particular, corresponding to the annular preferred design of the hollow coil 20, the corresponding driving member 11 is also preferably configured as a cylinder or a cylindrical body, and the return member 12 is configured as a disc or a cylindrical body. A type of cylinder, so that when the suspended magnetic component 10 moves relative to the hollow coil 20, the magnetic field lines in all directions are disturbed uniformly, and the resulting magnetic flux changes more uniformly, ensuring that the self-resetting suspended magnetic type The power generation process of the generator 100 produces a degree of uniformity of electric power.

[0209] It is worth mentioning that, specifically in these embodiments of the present invention, the driving member 11 is designed in a cylindrical shape and has a taper at one end away from the return member 12 to form a type of cylinder., based on the tapered design of the driving part 11, the pressing strength of the driving part 11 is improved. When an external force is applied to the tapered driving part 11, the driving force is relatively centered, thereby preventing the driving part 11 from moving. This further ensures the stability of the return member 12 during movement and prevents the return member 12 from turning over or preventing the entire abutting portion 121 of the return member 12 from being synchronized. Separated from the drive tube 312 , one end of the drive member 11 close to the return member 12 has a drive groove that is recessed toward the other end of the drive member 11 , so as to reduce the risk based on the recessed design of the drive member 11 The direct contact area between the driving part 11 and the return part 12 is conducive to reducing the direct impact area between the driving part 11 and the return part 12 and extending the service life of the self-resetting suspended magnetic generator 100 , and at the same time, it is beneficial to reduce the noise of the self-resetting suspended magnetic generator 100.

[0210] Particularly, in this embodiment, the diameter of the return member 12, which is provided in the form of a disc, is larger than the aperture of the driving hole 311, so that when the return member 12 is provided at the suspended magnetic channel ensures that the return member 12 is magnetically attracted to the top cover 31 when at least one of the driving member 11 and the return member 12 is a permanent magnet.

[0211] It is worth mentioning that in some embodiments, the top end of the driving member 11 can also be set in a flat-top shape or a dome shape to facilitate direct pressing and driving by hand, wherein the return body 12 is provided In order to perform piston movement along the hollow channel 201 of the hollow coil 20, when the return body 12 is pushed by the driving member 11, when the pushing force is large enough, it can overcome the pair of return bodies 12. When the magnetic attraction force of the drive tube 312 is combined, the return body 12 and the drive tube 312 are quickly separated instantly, but they still maintain mutual attraction and have the magnetic force to automatically reset. 12 flies in the direction of the bottom cover 32 at a high speed in the hollow channel 201 of the hollow coil 20 at a set speed, and a first induced electromotive force is generated in the hollow coil 20; when the force pushing the driving member 11 When released, the return body 12 rebounds under the action of magnetic attraction. The return body 12 attracts the drive tube 312 again and generates a second induced electromotive force in the hollow coil 20 .

[0212] It is worth mentioning that in some embodiments, in order to further reduce costs and simplify the structure, the driving member 11 can be disposed inside the key of the corresponding housing, that is, the driving member 11 is integrally formed with the key of the corresponding housing., when the button of the housing is pressed, the driving member 11 located in the housing extends into the driving tube 312 to drive the return body 12 . Moreover, the driving member 11 can also be configured as a rubber piece, which has elasticity and improves the pressing feel. The driving member 11 made of rubber can also be integrally formed with a waterproof membrane and covered in the present invention, which is both waterproof and functional. To reduce the beneficial effect of noise, the waterproof membrane can be wrapped around the self-resetting suspended magnetic generator 100 .

[0213] Particularly, when the driving member 11 is configured as a rubber member, the cross section of the side where the driving member 11 abuts against the return member 12 is a plane or a hollow cylindrical annular structure.

[0214] Particularly, in some embodiments, when the return body 12 is driven, the contact portion 121 of the return body 12 and the bottom opening 321 of the lower cover 32 are The inner edge is substantially flush; optionally, in some embodiments, when the return body 12 is driven, the other side opposite to the abutment portion 121 of the return body 12 protrudes from the The bottom opening 321 of the bottom cover 32; optionally, in some embodiments, in the initial state, the other surface of the abutment portion 121 of the return body 12 protrudes from the bottom cover 32 The bottom opening 321 is not limited by the present invention.

[0215] It is worth mentioning that the central arrangement and central driving method of the driving member 11 disclosed in the present invention greatly simplifies the complexity of the housing design. It is only necessary to set a vertical button above the driving member 11. Can be commercialized; the central arrangement and central driving method of the driving member 11 of the present invention can significantly reduce the volume of the product, as well as the stability during operation, compared with the side driving method of the prior art. The energy generated each time tends to be consistent, and the mechanical noise is significantly reduced compared with the existing technology.

[0216] In particular, compared to the hand- pressed generator of the prior art, the present invention can set the output electric power as needed. The miniature hand-pressed generator of the prior art has upper and lower magnetic conductive plate limits and needs to be specially connected with the magnets are fixed together. Therefore, if you want to increase the output power of the generator, you must increase the volume of the magnets. However, due to the limitations of the upper and lower magnetic conductive plates and fixings, the volume of the magnets is difficult to change, so it is inconvenient to adjust the output power of the generator; According to the present invention, the thickness of the return member 12 can be appropriately increased or reduced to adjust the power generation. Since there is no component fixedly connected to the return member 12, the volume of the return member 12 is the change does not affect other components, and it is relatively easy to increase or decrease the thickness of the return member 12 . For example, approximately 200uJ of energy is required to drive an FSK-standard communication circuit, and approximately 300uJ of energy is required when switching to an ASK-standard communication circuit. At this time, the power generation power can be adjusted by replacing the return member 12 of the corresponding thickness without re- Adjusting the structure of the generator does not require re-opening

[0217] In particular, based on the purpose of improving the operating feel of the self-returning suspended magnetic generator 100, the present invention also provides a spring in the self-returning suspended magnetic generator 100 to enhance the self-returning suspended magnetic generator. For the pressing feel of the magnetic generator 100, refer specifically to Figure 16, in which the magnetic suspension assembly 10 further includes a force storage member 13, wherein the force storage member 13 is driven by the driving member 11 to drive the return member 12 And before overcoming the magnetic attraction force between the return member 12 and the top cover 31, it is driven by the driving member 11 to accumulate potential energy and generate deformation to form a forced displacement of the driving member 11, thereby This avoids the sudden displacement of the driving member 11 when it overcomes the magnetic attraction force between the return member 12 and the top cover 31 , thereby improving the pressing feel of the self-resetting suspended magnetic generator 100 , and due to the storage The potential energy of the force member 13 is instantly released, thereby accelerating the movement of the return member 12 and further improving the power generation efficiency of the self-resetting suspended magnetic generator 100 .

[0218] Specifically in this embodiment, the force accumulating member 13 is disposed between the driving member 11 and the return member 12, wherein when the driving member 11 is stressed, the driving member 13 is the driving force of the member 11 first acts on the force storage member 13. The force storage member 13 is deformed under the driving of the driving member 11 to accumulate the driving force of the driving member 11. The driving member 11 continues Applying a driving force, the force accumulating member 13 conducts the driving force of the driving member 11 to the return member 12 until the magnetic attraction force between the return member 12 and the top cover 31 is overcome, so that the return member 12 moves along the suspended magnetic channel, thereby forming a change in magnetic flux to generate electrical energy, thus preventing the driving member 11 from overcoming the magnetic attraction between the return member 12 and the top cover 31 at the moment The sudden displacement improves the pressing feel of the self-returning suspended magnetic generator 100. When the driving force of the driving member 11 is canceled, the return member 12 is attracted by the magnetic attraction of the top cover 31. Return, the force storage member 13 forms a return buffer for the return member 12, avoiding direct impact between the return member 12 and the driving member 11, which is beneficial to extending the self-returning suspended magnetic generator. The service life of 100, and at the same time, based on the buffering force of the return member 12 by the force storage member 13, the sudden upward ejection impact of the drive member 11 can be avoided, ensuring the stability of the corresponding key and ensuring the self-reset. The suspended magnetic generator 100 is safe to use.

[0219] In particular, the force storage member 13 disposed between the driving member 11 and the return member 12 can be installed with the help of the objectively existing space of the driving member 11 to ensure that the automatic the reset suspension magnetic generator 100 is miniaturized and miniaturized. Specifically, the force accumulating member 13 is accommodated in the driving groove of the driving member 11 and presses the return member 12, so that with the help of the recessed driving groove of the driving member 11 is provided to make the structure of the self-returning suspended magnetic generator 100 more compact.

[0220] It is worth mentioning that in some embodiments of the present invention, the driving member 11 can be divided into two sections, that is, the driving member 11 can be composed of two superimposed sections, and the force storage member 13 is arranged between the two sections of the driving member 11, so as to avoid the uneven end surface of the force-accumulating member 13 or the unbalanced rocking motion of the elastic element causing the driving member 11 to drive the return member 12. tilt, thereby ensuring the working stability of the self-resetting suspended magnetic generator 100.

[0221] Refer specifically to Figure 17 of the accompanying drawings of the present invention, in which the driving member 11 is composed of two sections, so that the force storage member 13 can be hidden inside the driving member 11, which reduces the The extra space required by the force storage member 13 makes the overall structure of the self- returning suspended magnetic generator 100 more compact. The driving member 11 includes a first driving member 111 and a second driving member 112, so The force storage member 13 is disposed between the first driving member 111 and the second driving member 112 of the driving member 11. Preferably, the first driving member 1101 and the second driving member 1102 connect the The force- accumulating member 13 is wrapped so that the driving member 11 has elasticity when it is pressed and driven.

[0222] Optionally, in some embodiments, the second driving member 112 is provided below the force storage member 13. This is to prevent the force storage member 13 from being compressed and storing force. Inclined, this will cause the periphery of the return member 12 to be unable to separate from the drive tube 312 in a balanced and simultaneous manner. This unbalanced separation The second driving member 1102 has the function of maintaining the balanced axial movement of the force storage member 13. The second driving member 112 may be configured as a flat-bottomed barrel. The second driving member 112 with a flat-bottomed barrel design The barrel-shaped side will not swing left and right under the limiting effect of the driving hole 311, thereby making the piston movement of the driving member 11 more stable.

[0223] It is worth mentioning that in this modified embodiment, the self-returning suspended magnetic generator 100 further includes an upper cover 51 and a lower cover 52, wherein the upper cover 51 and the lower cover 52 The lower cover 52 covers the upper and lower boxes to completely wrap the self- returning suspended magnetic generator 100. The middle part of the upper cover 51 has an opening concentric with the top cover 31, so that the driving member 11 The top end can be protruded, and the upper cover 51 can movablely limit the driving member 11 to ensure that the driving member 11 will not fall off the self-returning suspended magnetic generator 100. The lower cover 51 can flexibly limit the driving member 11. There is a through hole at the center of the bottom of 52, and the through hole has a thickness of less than 6 mm to ensure the movement stroke of the return member 12 and to ensure that the return member 12 will not hit other objects and emit a strong sound when moving, noise.

[0224] In particular, in some embodiments, based on the purpose of preventing the return member 12 from hitting other objects during movement and emitting strong noise, the return member 12 is deviated from the drive tube 312 when the return member 12 is moved. A buffer member is also provided on one side of the return member 12. When the return member 12 hits the buffer member, the noise generated by the return member 12 colliding with other components during the piston movement can be reduced. The buffer member The parts are made of shock-absorbing materials such as rubber, sponge, and shock- absorbing shrapnel.
