Description

Power generation device, power generation method, reset method and application thereof

Technical Field

The invention relates to the field of self-power generation, in particular to a power generation device, a power generation method, a reset method and application thereof.

Background

The self-generating wireless switch powered by the built-in micro-generator is accepted by the masses in the concept of energy conservation and environmental protection, however, the self-generating wireless switch in the prior art has obvious defects, firstly, the pressing force required by driving the self-generating wireless switch to work is large, and the hand feeling is relatively hard; secondly, the large impact noise generated by the 'snap' of the internal generator when the self-generating wireless switch is operated by pressing brings bad experience to users, and especially the noise generated when the self-generating switch is used in quite places at night is harsher. Therefore, it is necessary to further reduce the driving force required for the self-generating wireless switch and reduce the mechanical noise of the micro-generator.

The reset type self-generating switch in the prior art needs a spring with a reset force larger than the driving force to reset, and the power generation devices disclosed in patent publication numbers CN106462127B and CN104656479B need a reset spring with larger elasticity, so that the reset type self-generating switch is very laborious to press and operate; the patent with publication number CN208564883 discloses a device for cyclic power generation, but the design is complex, the precision requirement on parts is very high, the cost is high, and the popularization and the application are not facilitated.

As shown in fig. 1, a driving manner of publication CN106462127B is disclosed, when the magnetic group of the generator of the self-generating wireless switch is pressed, the pressing force needs to be very large due to the reverse thrust of the return spring; assuming that the driving force required to drive the generator magnet assembly to move downward is 3N without a return spring, it is preferable that the force of the return spring is set to 1.5 times the driving force of the generator magnet assembly if the return is to be smooth. That is, if the driving force required to drive the generator magnet assembly is 3N, the power generation device is made to have a function capable of being reset by the spring, and the total driving force is: 3N (magnetic group driving force) +3×1.5 (return spring reverse thrust) =7.5n. It can be seen that the 7.5N driving force is still quite laborious, even though a lever may be employed in the driving means of the self-generating wireless switch to reduce part of the driving force, the strong driving force required by the generator causes the housing of the self-generating wireless switch to be vibrated to give off harsh mechanical noise.

When some self-generating wireless switch products are designed, in order to enable the thickness of the self-generating wireless switch to be thinner, the thickness of the self-generating wireless switch is matched with the thickness of a traditional socket, the self-generating wireless switch is enabled to be highly consistent in appearance, the self-generating wireless switch is good in attractive appearance, therefore, the self-generating wireless switch is required to be realized by a power generation device with extremely light strength, deformation is not easy to occur after the self-generating wireless switch is thinned only by the power generation device, otherwise, the problem that the position of the edge of a key can fail when the key is pressed due to rigidity reduction after the key and the shell of the self-generating wireless switch are thinned is caused by the design of the prior art.

Fig. 2 discloses a resetting device of publication CN104656479B, which also has a counter spring that is larger than the driving force of the generator, and likewise has a counter spring with a counter force that is larger than the driving force of the generator, resulting in a great effort when the finger presses the key.

Fig. 3 discloses an elastic resetting device in the patent publication number CN209472525U, and under the high-speed driving of the elastic sheet, the iron core impacts the upper and lower magnetic conductive plates to emit 2 times of strong mechanical noise. The prior art can generate strong mechanical noise, which very influences the effect of actual use. In the prior art, the iron core is alternately impacted with the upper and lower magnetic conductive plates at high speed under the acceleration action of the mechanical energy storage elastic sheet so as to change the direction of a magnetic induction line passing through the iron core, thereby generating induced energy in the coil, if the impact speed between the iron core and the upper and lower magnetic conductive plates is faster, the induced energy is bigger, the side effect is that the impact noise is bigger, and the mechanical noise is unacceptable. In this design, spring-like acceleration devices are used, which can cause the core to strike the upper and lower magnetic plates louder.

In the prior art, the reset type self-generating switch needs a reset spring with larger force to implement the reset function, and the force of the reset spring is larger than the driving force of the power generation device to normally reset, so that the two overlapped driving forces are very large due to the fact that the spring reset force and the driving force of the power generator are very large, the design cannot be applied to a remote controller device, and as is well known, the pressing hand feeling of remote controllers such as televisions and air conditioners is very light, and the noise is very low; if the power supply requirement of the remote controller is to be met, the power and noise of the power generation device are extremely high.

Therefore, there is a need to improve the problems of the prior art that the operation of a self-generating wireless switch is very laborious and that the mechanical impact noise is large.

Referring to fig. 4 to 7C of drawings of the present specification, a driving apparatus 100 and a power generating apparatus with the driving apparatus according to a first preferred embodiment of the present invention are explained in the following description. The power generation device further comprises a power generator 200, wherein the power generator 200 and the driving device 100 are mutually linked, the power generator 200 is driven by the driving device 100 under the stress, and the power generator 200 is driven by the driving device 100 to generate induced electric energy. It should be noted that in the preferred embodiment of the present invention, the generator 200 is a micro-generator. It will be appreciated by those skilled in the art that only the main structure of the power generation device is shown in the drawings of the present invention, wherein the power generation device further comprises a housing, wherein the power generator 200 and the driving device 100 are provided in the housing. It will be appreciated that in the preferred embodiment of the present invention, the number of driving devices 100 may be one, two or more. That is, there is no limitation on the number of the driving devices 100 of the power generation device.

The driving device 100 includes a driving rack 10, an energy accumulator 20, at least one brake 30, and at least one magnetic attraction unit 40, wherein the brake 30 is attracted to the magnetic attraction unit 40, and the brake 30 conducts the magnetic force of the magnetic attraction unit 40. In a stationary state or an initial state, the driving bracket 10 of the driving device 100 is attracted to the stopper 30, that is, the magnetic attraction unit 40 attracts the driving bracket 10 through the stopper 30. When the driving bracket 10 receives a sufficient force, the magnetic attraction unit 40 is separated from the brake 30, that is, when the driving bracket 10 receives a sufficient driving force, the driving force overcomes the magnetic attraction force of the brake 30 and the driving bracket 10. It should be noted that the generator 200 is drivingly connected to one end of the driving bracket 10, and the driving bracket 10 drives the generator 200, so that the generator 200 generates induced electric energy.

The brake 30 is attracted to the magnetic attraction unit 40 and keeps relatively stationary in the magnetic attraction unit 40, wherein the brake 30 may be, but is not limited to, iron, cobalt, nickel, other metals and alloys with magnetic force transmission, or magnets, etc.

In an initial state, the stopper 30 and the magnetic unit 40 are fixed, wherein the magnetic unit 40 adsorbs the driving bracket 10 through the stopper 30 so that the driving bracket 10 is held at the stopper 30 by the adsorption of the magnetic unit 40. The energy store 20 is arranged to the drive carriage 10, wherein the energy store 20 is adapted to store energy for driving the movement of the drive carriage 10. When the accumulator 20 stores enough energy, the accumulator 20 drives the driving bracket 10 to move, whereby the driving bracket 10 drives the generator 200 to generate induced electric energy.

Preferably, in the preferred embodiment of the present invention, the accumulator 20 is fixed to the driving bracket 10, wherein the accumulator 20 is used to store a driving force required to drive the driving bracket 10, and when the accumulator 20 stores a sufficient driving force, the driving bracket 10 is driven by the accumulator 20 and overcomes a magnetic attraction force between the driving bracket 10 and the brake 30. In other words, when the driving device 100 is stressed, the energy accumulator 20 stores driving force for the driving rack 10, and when the driving rack 10 exceeds a critical state, the driving rack 10 is driven by the energy accumulator 20 to move, so that the driving rack 10 drives the generator 200 to generate induced electric energy. Alternatively, the accumulator 20 is integrally formed to the driving bracket 10, i.e., the accumulator 20 integrally extends from one end of the driving bracket 10.

The driving bracket 10 is initially attracted to the stopper 30, and when the accumulator 20 stores a sufficient driving force, the accumulator 20 drives the driving bracket 10 to move in a specific direction. Illustratively, in the preferred embodiment of the present invention, the driving bracket 10 is moved in parallel by the accumulator 20 in a direction opposite to the stopper 30, or the driving bracket 10 is rotated in a direction opposite to the stopper 30 based on a rotation axis.

Preferably, the driving bracket 10 has a pivot axis L, wherein when the accumulator 20 stores a sufficient driving force, the accumulator 20 drives the driving bracket 10 to perform a pivoting motion based on the pivot axis L to drive the generator 200 to generate induced electric energy. Alternatively, the driving bracket 10 has a moving track, wherein when the accumulator 20 stores a sufficient driving force, the accumulator 20 drives the driving bracket 10 to move horizontally or vertically in a direction opposite to the stopper 30 based on the moving track to drive the generator 200 to generate the induced electric energy.

The driving bracket 10 includes a driving part 11, at least one transmission part 12 extending from the driving part 11, and at least one rotation shaft 13, wherein in an initial state, the driving part 11 is adsorbed to the brake 30, and the accumulator 20 is disposed at the driving part 11. When the accumulator 20 stores a sufficient driving force, the accumulator 20 drives the driving part 11 of the driving bracket 10 such that the driving part 11 is disengaged from the brake 30. The driving part 11 and the transmission part 12 are positioned at both sides of the rotating shaft 13, wherein when the driving part 11 receives a sufficient driving force, the driving part 11 and the transmission part 12 do a pivoting motion with the rotating shaft 13 as an axle center (fulcrum). The transmission part 12 is drivingly connected with the generator 200, and when the transmission part 12 moves, the transmission part 12 drives the generator 200 to generate induced electric energy.

Preferably, the driving part 11, the transmission part 12 and the rotating shaft 13 of the driving bracket 10 are integrally formed. The transmission part 12 integrally extends outwards from two sides of the driving part 11, wherein the rotating shaft 13 is located between the driving part 11 and the transmission part 12, and the rotating shaft 13 is located in the same axis direction of the pivot shaft L.

It should be noted that, in the preferred embodiment of the present invention, the driving portion 11 has magnetic attraction performance, that is, the driving portion 11 can be attracted by the brake 30, and a portion of the driving portion 11 corresponding to the brake 30 is made of a magnetically conductive material, or an attraction unit of the magnetically conductive material is disposed at a portion corresponding to the brake 30. Alternatively, in the preferred embodiment of the present invention, the specific materials, structures and shapes of the transmission part 12 and the rotation shaft 13 of the driving bracket 10 are not limited herein.

As an example, the driving bracket 10 has a shape of "C" type and "N" type, including but not limited to "U" type and "Y" type, and the transmission parts 12 located at both sides of the driving part 11 are drivingly connected to the generator 200, and when the driving part 11 moves, the transmission parts 12 located at both sides of the driving part 11 drive the generator to generate electricity.

As shown in fig. 4 and 5, in a stationary state, the magnetic attraction unit 40 attracts the driving rack 10 through the stopper 30, wherein the stopper 30 provides magnetic resistance so that the driving rack 10 can maintain a stable stationary state; wherein the brake 30 provides detent force, and the energy accumulator 20 together form ejection accelerating device, when the energy accumulator 20 stores enough driving force, the driving bracket 10 can be quickly separated from the brake 30 when enough driving force is overcome to provide detent force by the brake 30; wherein the brake 30 is further capable of providing an automatic restoring force, and when the force stored in the accumulator 30 is removed, the brake 30 attracts the driving part 11 of the driving bracket 10 by magnetic attraction, so that the driving bracket 10 returns to the initial position.

The accumulator 20 is disposed on the driving part 11 of the driving bracket 10, wherein the accumulator 20 stores a force when being stressed, so that the accumulator 30 drives the driving part 11 of the driving bracket 10 to be separated from the brake 30 when the force stored by the accumulator 20 reaches the magnetic resistance of the brake 30. The accumulator 20 includes a fixed end 21 and an accumulator end 22 integrally extending outwardly from the fixed end 21, wherein the fixed end 21 of the accumulator 20 is fixed to the driving part 11 of the driving bracket 10, and the accumulator 20 is located outside the driving part 11 of the driving bracket 10. Preferably, the energy storage 20 is an elastic energy storage mechanism, such as an elastic sheet, and as an example, in this preferred embodiment of the present invention, the energy storage 20 is implemented as a metal elastic sheet or a plastic elastic sheet. The accumulator 20 is fixedly provided to the driving portion 11 of the driving bracket 10.

It should be noted that the force application point of the energy accumulator 20 is located at the energy storage end 22 of the energy accumulator 20, and when the energy storage end 22 of the energy accumulator 20 is stressed, the energy storage end 22 of the energy accumulator 20 is stressed to bend so as to store the kinetic energy of the applied force. When the accumulator 20 stores enough kinetic energy, the accumulator 20 is enough to overcome the magnetic attraction resistance between the driving bracket 10 and the brake 30, so that the driving bracket 10 is rapidly separated from the brake 30 under the elastic driving action of the accumulator 20.

In the preferred embodiment of the present invention, the driving bracket 10 is pivotally mounted to the housing of the power generation device, the magnetic attraction unit 40 and the brake 30 are fixedly mounted to the housing, and in an initial state, the brake 30 is attracted to the driving part 11 of the driving bracket 10 by magnetic force. Therefore, in a normal state, the driving bracket 10 is not allowed to move arbitrarily under the constraint of the magnetic force of the magnet, and the driving bracket 10 is attracted by the stopper 30 to maintain the attracted initial state.

If pressure is gradually input to the energy storage end 22 of the energy storage device 30, the energy storage device 20 starts to bend and store elastic potential energy, and when the energy storage device 20 is storing energy, the brake 30 adsorbs the driving portion 11 of the driving bracket 10 through the magnetic force, and the driving portion 11 still maintains the adsorption state of being tightly attracted to the brake 30. As the input force continues, the accumulator 20 continues to deform and bend, and the stored elastic potential energy becomes larger and larger; when the elastic potential energy is greater than the magnetic attraction force, the energy accumulator 20 suddenly releases the elastic potential energy, and the driving part 11 instantaneously disengages from the attraction of the brake 30.

The driving part 11 is instantaneously separated from the brake 30, and the movement direction of the driving part 11 is a direction separating from (or away from) the brake 30, and not a direction hitting the brake 30, so that the driving part 11 does not generate noise or generates only a very slight sound during the separation of the brake 30, thereby achieving the purpose of reducing noise.

The separation of the driving part 11 from the brake 30 causes the driving bracket 10 to swing rapidly, wherein the transmission part 12 moves rapidly instantaneously, and the tail end of the transmission part 12 and the micro-generator are interlocked, so that the micro-generator can be driven at a very high speed, thereby generating strong induced electric energy.

It should be noted that the brake 30 may be fixedly mounted to the housing, and the brake 30 performs both braking and magnetic conduction. To further increase the magnetic permeability and the efficiency of power generation, the coils may be wrapped or semi-wrapped around the brake 30 with a magnetically permeable material to concentrate the magnetic induction lines.

The generator 200 is the micro-generator, and the generator 200 includes a generator fixing device 210 and at least one air coil 220, wherein the air coil 220 is movably disposed on the generator fixing device 210. The generator fixture 210 has a magnetic gap 201, and the air coil 220 is movable within the magnet and generates induced electrical energy during movement. The air-core coil has a small mass and a relatively light weight, and is beneficial to being driven by the driving bracket 10 at a high speed to generate relatively strong induced electric energy. Since the air coil 220 is free to move in the magnetic gap, there is little friction, and thus no significant mechanical noise is generated, which is advantageous for further reducing noise when the generator is operated.

Preferably, in the preferred embodiment of the present invention, the number of turns of the air coil of the generator 200 is less than 800 turns, and in order to improve the efficiency of power generation, the height of the air coil 220 is less than 6 mm. In particular, since the air core coil 20 moves in the magnetic gap, the inner wall thereof is inevitably rubbed against the magnetic conductive material of the magnetic gap, thereby damaging the coil, and in order to overcome this problem, a rigid film with a thickness of less than 0.5 mm is laid on the inner wall of the air core coil 220 to protect the moving coil.

The generator 200 further comprises a coil driving plate 230, wherein the air coil 220 is disposed on the coil driving plate 230, and the air coil 220 is driven by the coil driving plate 230 to perform a motion of cutting the induction lines in the magnetic gap 201 of the generator fixing device 210. The coil driving plate 230 serves to fix the air coil 220 and to movably connect the transmission part of the driving bracket 10, and when the driving bracket 10 swings, the transmission part 12 of the driving bracket 10 transmits movement energy to the coil driving plate 230, thereby driving the air coil 220 fixed to the coil driving plate 230 to move in the 201 magnetic gap.

Accordingly, the coil driving plate 230 is drivingly connected to the driving part 12 of the driving bracket 10, and the coil driving plate 230 is driven to move by the driving part 12, whereby the coil driving plate 230 drives the air coil 220 to move. It should be noted that the coil driving plate 230 is located at the top end of the air core coil 220.

Coil drive fulcrums 202 are provided on both sides of the coil drive plate 230, wherein the transmission portion 12 of the drive bracket 10 is drivingly connected to the coil drive fulcrums 202 of the coil drive plate 230. It should be noted that the specific connection manner of the coil driving support 202 and the driving support 10 is not limited, as long as the driving support 10 can transmit the driving force to the coil driving support 202 when swinging, so that the air-core coil 220 can move in the magnetic gap 201.

Preferably, the coil driving plate 230 is connected to the driving frame 10 by a shaft or a slot. More preferably, the driving bracket 10 may be provided in a U-shaped, Y-shaped, I-shaped, T-shaped, mouth-shaped, pi-shaped, etc. structure.

When the external force is removed, the driving bracket 10 is magnetically reset by the magnetic field of the brake 30, and the brake 30 is re-attracted to the driving part 11 to return to the initial state. In particular, since the driving part 11 has been disengaged from the suction action of the brake 30, the driving part 11 is still in the attractive force action range of the magnetic field conducted by the brake 30 since the disengaged stroke is small, for example, less than 0.5 mm. Therefore, once the force driving the accumulator 20 is removed, the driving part 11 will still return to the original position under the action of the force of the magnetic field, that is, the driving part 11 will automatically re-engage with the brake 30, and no noise will be generated or only a very light sound will be generated when the driving part 11 is reset, because there is no acceleration of the accumulator 20 when the driving part is reset. Thus, the reset process also achieves noise reduction.

According to the description of the above embodiments, it can be seen that the present invention does not use the reset spring of the prior art, but still has the effect of resetting, and even achieves the beneficial effects of automatic resetting; the driving force of the present invention is lighter because of the lack of reverse thrust of the return spring, that is, the efficiency of the present invention is significantly improved with the same energy generation.

From the above disclosure, it is further noted that if two magnetically conductive metals are magnetically attracted together by magnetic force, the coil is further sleeved around the outer periphery of either magnetically conductive metal. In the initial state, the magnetic induction wires in the two magnetic conduction metals are in a stable state, and when the two magnetic conduction metals are separated by adopting mechanical force, the magnetic induction wires passing through the magnetic conduction metals are subjected to strength change due to separation action, so that induced electric energy can be generated in the coil. If the distance separating the two magnetically permeable metals is still in the reset range of the strong magnetic field, although the two magnetically permeable metals have been separated, electrical energy is also generated in the coil. However, under the action of the attraction force of the magnetic force, when the mechanical force is released, the two magnetic conductive metals can return to the initial state again under the action of the attraction force of the magnetic force, and the two magnetic conductive metals can be automatically adsorbed together, so that the double functions of power generation and automatic reset are realized through the magnetic force. In short, the invention utilizes the magnet at the same position and realizes the function of generating electricity and also has the function of resetting; the magnet can be formed by combining a plurality of pieces according to the required magnetic force requirement, and the invention is not limited.

In particular, it is assumed that the distance separating the two magnetically conductive metals due to mechanical forces is far beyond the effective distance that can be automatically reset by magnetic traction. Then, only a reset device with smaller force is needed to lightly push the two magnetic conductive metals to return to the initial state. As shown in fig. 7C, the power generation device further includes a reset device 300, wherein the reset device 300 is disposed on the housing of the power generation device, and when the magnetic attraction unit of the power generation device is driven to be separated from the brake 30, the driving bracket 10 is driven by the reset device 300 to return to the initial position. In particular, when the driving bracket 10 is separated from the stopper 30 far, the reset device 300 can assist the driving bracket 10 to move, providing a force that is advantageous for the driving bracket 10 to return to the original state. It should be noted that in the preferred embodiment of the present invention, the force provided by the reset device 300 is much less than the force required to drive the two magnetically permeable metals apart, unlike the prior art. Therefore, the resetting of the invention is still very labor-saving, and the other labor-saving purpose of the invention is achieved, so that the resetting still belongs to the protection scope of the invention.

In other alternative embodiments of the invention, the resetting device 300 may also be arranged to act on the energy storage end 22 of the energy storage 20, wherein the resetting device 300 provides the auxiliary force required for resetting via the energy storage end 22 of the energy storage 20.

The "smaller force" described above means that the force required for resetting the above-described power generation device is smaller than the force required for driving the two magnetic conductive metals to separate. Preferably, the force required for resetting is less than 1/2 of the force driving the separation of the two magnetically permeable metals. The reset device 300 may be implemented using a repulsive or attractive force of a leaf spring, a torsion spring, or a magnet.

Referring to fig. 8 of the drawings, a driving apparatus 100 and a power generating apparatus with the driving apparatus according to a second preferred embodiment of the present invention are explained in the following description. Unlike the first preferred embodiment described above, the driving device 100 includes a driving rack 10, an energy accumulator 20, at least one brake 30, and at least one magnetic attraction unit 40, wherein the brake 30 is attracted to the magnetic attraction unit 40, and the brake 30 conducts the magnetic force of the magnetic attraction unit 40.

In the preferred embodiment of the present invention, the driving apparatus 100 further includes at least one power generating coil 50 provided to the driving bracket 10 such that the power generating coil can be disturbed by the magnetic field of the magnetic attraction unit 40 to generate electric power when the driving bracket moves. The power generation coil 50 is wound around the driving bracket 10, and preferably, in the preferred embodiment of the present invention, the power generation coil 50 is wound around the driving end 11 of the driving bracket 10, and the power generation coil 50 can generate induced electric energy when the driving bracket 10 is forced to be driven to be separated from the brake 30 and/or when the driving bracket 10 is reset by the magnetic attraction force of the brake 30.

It will be appreciated that the location where the drive bracket 10 interacts with the brake 30 and the location where the power generating coil 50 is sleeved are magnetically permeable, while other locations may be magnetically non-permeable;

the driving support 10 may be made of a magnetically conductive material, or a combination of a magnetically conductive material and a non-magnetically conductive material, such as a combination of an iron-nickel alloy and a plastic;

under the drive of external force, after the drive support 10 is separated from the brake 30, the drive support 10 and the brake 30 can be reset by using a force smaller than the separation force of the drive support 10 and the brake 30, so that the purpose of saving labor is achieved.

The power generating coil 50 is sleeved on the driving bracket 10, preferably, one or more power generating coils 50 can be arranged to enhance the output capability of the induction electric energy;

in particular, in some embodiments, it is also possible to provide that the magnet 40 moves with the brake part, while the drive bracket part is stationary; that is, in some variant embodiments, the brake iron 30 and the drive bracket 10 are in a state of relative motion, and do not limit which component is moved or fixed.

As shown in fig. 14, in particular, in order to further enhance the induced energy of the power generation coil 50, the present embodiment may further provide a magnetism collecting unit 60B on the other side of the magnetic attraction unit 40, that is, opposite to the brake 30, to enhance the density of the magnetic induction lines passing through the power generation coil 50.

In this embodiment, after the brake 30 is separated from the driving bracket 10, the brake 30 is close to the magnetism collecting unit 60B to strengthen the magnetic field strength in the brake.

In particular, in the present embodiment, the driving bracket 10 is pivotally moved, and in some embodiments, the driving bracket 10 may be further configured to vertically move up and down, regardless of the movement mode of the driving bracket 10, so long as the effect of separating from the brake 30 or saving labor is achieved, which is within the scope of the present invention.

It should be noted that the energy accumulator 20 and the driving bracket 10 may be riveted, or connected by plastic and metal parts, or the driving bracket 10 and the energy accumulator may be integrally formed by plastic packaging.

Referring to fig. 9 to 13C of drawings of the present specification, a driving apparatus 100A and a power generating apparatus with the driving apparatus 100A according to a third preferred embodiment of the present invention are explained in the following description. The power generation device further includes at least one coil 200A, wherein the coil 200A is disposed at the driving device 100A, and the coil 200A is driven by the driving device 100A to generate induced electric energy.

In detail, the driving device 100A includes a driving rack 10A, an energy accumulator 20A, a brake 30A, and at least one magnetic attraction device 40A, wherein the brake 30A is attracted to the magnetic attraction device 40A, and the brake 30A conducts the magnetic force of the magnetic attraction device 40A. It should be noted that the power generation device further includes a housing, wherein the driving device 100A is disposed in the housing. The brake 30A is fixedly disposed on the housing, wherein the energy accumulator 20A is disposed on the driving support 10A, and the driving support 10A has a movable pivot, and the driving support 10A rotates around the movable pivot when the driving support 10A receives a sufficiently large driving force. The coil 200A is disposed on the actuator 30A, and when the driving bracket 10A rotates around the movable pivot, the coil 200A generates induced electric energy in the magnetic field generated by the magnetic attraction means 40A.

It should be noted that the energy accumulator 20A includes a fixed end 21A and an energy storage end 22A extending outwardly from the fixed end 21A, wherein the fixed end 21A is fixed to the driving bracket 10A, and the energy storage end 22A extends outwardly from the fixed end 21A. When the energy storage end 22A of the energy storage 20A is stressed, the energy storage end 22A is bent and deformed, and stores elastic potential energy. It is understood that the energy accumulator 20A may be, but is not limited to, a metal spring, a plastic spring, or may be formed integrally with the driving frame 10A by plastic packaging.

In the preferred embodiment of the present invention, the magnetic attraction means 40A is fixed to the driving bracket 10A, and the magnetic attraction means 40A can be rotated in synchronization with the driving bracket 10A. The driving bracket 10A includes at least one pivot end 11A and a driving end 12A extending from the pivot end 11A, wherein the movable pivot is located at the pivot end 11A of the driving bracket 10A, and the magnetic attraction device 40A is fixedly disposed at the driving end 12A of the driving bracket 10A. It should be noted that, in the initial state, the magnetic attraction device 40A and the brake 30A are attracted to each other, when the driving support 10A receives a sufficiently large driving force, wherein the driving force is opposite to the magnetic attraction force provided by the magnetic attraction device 40A, the driving support 10A drives the magnetic attraction device 40A to be separated from the brake 30A, that is, the driving support 10A drives the magnetic attraction device 40A to rotate, and changes the magnetic field direction of the magnetic attraction device 40A, so that the coil 200A located in the brake 30A generates induced electric energy.

It should be noted that, in the preferred embodiment of the present invention, the specific shape and implementation of the driving bracket 10A are not limited herein. By way of example, the drive bracket 10A may be, but is not limited to, U-shaped, Y-shaped, I-shaped, T-shaped, mouth-shaped, pi-shaped, etc. structures.

The magnetic attraction device 40A is fixedly arranged at the driving end 12A of the driving bracket 10A, wherein the driving end 12A of the driving bracket 10A can rotate around a movable supporting point of the driving bracket 10A when being stressed. It is worth mentioning that in this preferred embodiment of the invention, the brake 30A may be, but is not limited to, a metal or alloy or the like having magnetic conduction. By way of example, in this preferred embodiment of the invention, the brake 30A is a metallic or alloy material made of iron. The coil 200A is wound around the brake 30A.

The magnetic attraction device 40A further comprises at least one magnetic attraction unit 41A and at least one driving unit 42A, wherein the driving unit 42A is made of a material with magnetic permeability, and the driving unit 42A is disposed on the magnetic attraction unit 41A. In the initial state, the driving unit 42A is attracted to the brake 30A by the magnetic attraction unit 41A. The driving unit 42A may be, but not limited to, iron, cobalt, nickel, other metals and alloys having magnetic force transmission effect, or magnets, magnetite, etc.

The driving unit 42A includes a driving fixed end 421A and a driving extension end 422A integrally extended outward from the driving fixed end 421A, wherein the driving fixed end 421A of the driving unit 42A is fixed to the magnetic attraction unit 41A, the driving extension end 422A protrudes toward the stopper 30A, wherein the driving extension end 422A partially overlaps the stopper 30A so that the driving unit 42A and the stopper 30A are attracted to each other in an initial state. It will be appreciated that the brake 30A also prevents movement of the drive unit 42A to prevent misalignment of the drive unit 42A.

The magnetic attraction unit 41A may be, but not limited to, a magnet, or other element having a magnetic action.

Preferably, in the preferred embodiment of the present invention, the rotation angle of the driving bracket 10A based on the movable fulcrum is 45 degrees or less. In other words, the rotation of the driving end 12A of the driving bracket 10A about the pivoting end 11A swings at an angle of less than 45 degrees.

In particular, in the present embodiment, the driving bracket 10A is pivotally moved, and in some embodiments, the driving bracket 10A may be further configured to vertically move up and down, regardless of the movement of the driving bracket 10A, so long as the effect of separating from the brake 30A or restoring the brake with little effort is achieved, which falls within the scope of the present invention.

Unlike the first preferred embodiment described above, when the driving bracket 10A swings around the fulcrum, the driving unit 42A and the magnetic attraction unit 41A move synchronously, and the driving unit 42A is disengaged from the attraction of the brake 30A.

It should be noted that, the energy accumulator 20A is disposed at the driving end 12A of the driving bracket 10A, the elastic potential energy is stored by the energy accumulator 20A, and when the elastic potential energy stored by the energy accumulator is enough to overcome the acting force between the magnetic attraction device 40A and the brake 30A, the energy accumulator 20A releases the elastic potential energy to drive the driving bracket to swing at a high speed.

In a normal state, the magnetic attraction device 40A located at the driving end 12A is attracted to one end of the brake 30A under the action of magnetic force, and the driving end 12A is attracted to the brake to be locked. The drive bracket 10A is in a magnetically locked state and cannot swing freely. In this state, the magnetic field of the magnetic attraction means 40A is stably conducted to the brake 30A through the driving unit 42A, and the magnetic field is stable, so that no electric energy is induced in the coil at this time.

When the external force drives the energy input end of the energy accumulator 20A, the energy accumulator 20A cannot immediately drive the driving bracket 10A to swing because the driving end 12A is absorbed by the brake in advance, and the energy accumulator 20A begins to deform under the pushing of the external force and gradually stores elastic potential energy. The energy accumulator 20A continuously bends, the elastic potential energy is larger and larger, when the elastic potential energy stored by the energy accumulator 20A exceeds the magnetic attraction force of the magnetic attraction device 40A absorbed by the brake 30A, the driving support 10A rotates around the movable supporting point, so that the driving end 12A and the brake 30A are separated from each other, and the direction of mutual movement of the driving unit 42A and the brake 30A is opposite due to the separation. The driver end 12A and the brake 30A are spaced apart from each other rather than being co-current to each other, so that the separation process does not produce a "snap" impact sound, thereby contributing to a significant reduction in noise.

It is particularly pointed out that when the drive end 12A is separated from the brake 30A, momentary induced electrical energy is also generated in the coil 200A. Because, in a normal state, the driving end 12A and the brake 30A are attracted under the magnetic force of the magnetic attraction device 40A, the magnetic field stably passes through the brake 30; when the driving end 12A is separated from the brake 30A at a moment, the magnetic field density in the brake 30 is changed greatly, a changed magnetic field is generated, the magnetic energy density is reduced from a saturated state by eighty percent or more instantaneously, and induced electric energy is generated in a coil sleeved on the periphery of the brake 30 due to disturbance of the magnetic field caused by density change of a magnetic induction line.

In particular, the drive end 12A is separated from the brake for a relative time of less than 100 milliseconds to generate higher induced energy in the coil. Preferably, the distance between the magnetic attraction device 40A and the brake 30A is less than (including) 3 mm, so that after the magnetic attraction device 40A separates the brake 30A by a distance, when the external force is removed under the action of the magnetic field, the magnetic attraction device 40A can still automatically return under the action of the magnetic field, and the driving unit 42A and the brake 30A return to the attracted state from the separated state, that is, return to the normal state.

After the magnetic attraction device 40A is separated from the brake 30A by a distance, the magnetic attraction device and the brake are still in the range of magnetic field action. When the external force or the driving force is eliminated, the driving unit 42A and the brake 30A are automatically absorbed together under the condition of the magnetic field, and the elastic acceleration impact of the energy accumulator is avoided in the process of automatically absorbing together again, so that the process of absorbing the driving part and the brake 30A is quite, and the design purpose that the noise generated by the power generation device is quite small in the resetting operation is achieved.

Particularly, the invention discloses an automatic resetting labor-saving power generation device, wherein the magnetic field provided by the magnet not only plays a role in generating power, but also plays a role in automatically resetting the power generation device, so that the number of parts and the difficulty of mechanical design in the prior art are reduced, and the automatic resetting labor-saving power generation device has extremely high market value.

Of particular importance, as previously mentioned, the travel distance of the drive bracket 10A from the brake 30A is less than (including) 3 mm. Preferably, the separation distance is smaller than 0.5 mm, and the automatic resetting force and resetting effect by utilizing magnetic force are good. In a separation stroke of 0.5 mm, the power generation coil is capable of generating about 150uJ of energy sufficient to drive a radio frequency circuit to transmit 15 bytes of control data at a radio frequency power of 6 dB. Because if the distance of the drive end 12A from the brake 30A is relatively large, the magnetic force of the magnetic force reset is reduced due to the significant decrease of the magnetic force, the speed of the reset is reduced, and at this time, a spring with smaller force can be used to assist the semi-automatic reset of the power generation device.

In other words, in the preferred embodiment of the present invention, the driving device further comprises an auxiliary spring, wherein the auxiliary spring is disposed at the driving end 12A of the driving bracket 10A, and when the driving bracket 10A is driven such that the magnetic attraction device 40A is separated from the brake 30A, a restoring force is applied by the auxiliary spring to accelerate the driving bracket 10A to restore in time.

It is worth mentioning that this return-assist spring differs essentially from the prior art return springs, in that the thrust of the prior art spring is greater than the driving force of the generator, belonging to laborious devices; the thrust of the spring in the invention is far smaller than the force required by the driving of the generator, and belongs to a labor-saving component; as described above, in the prior art, if the driving force required by the generator during resetting is 3N, only 60% or less of the driving force is required for driving, so that the pressing force is significantly reduced, and the labor-saving effect is achieved.

Therefore, a significant feature of the present invention is that the force required for the reset operation of the power generation device is much smaller than the force required for the pressing operation, or that the force of the reset operation is smaller than 1/2 of the pressing operation force in the power generation device in the power-saving driving state.

When the brake 30A is disengaged from the driving end 12A, the magnetic attraction force between the brake 30 and the driving unit 42A is still in the range. When the input mechanical force is released, the brake 30A and the driving unit 42A automatically or passively return to the normal state by the magnetic attraction force, thereby reducing the driving force at the time of the reset operation. It should be noted that, in the above description, passive means that when the driving unit 42A is separated from the brake 30A too far, the reset operation is completed with insufficient force by the magnetic force, and therefore, an auxiliary device (or auxiliary spring) with smaller force is required to achieve the boost completion reset, which is called "passive" reset. The force of the spring return is very small, although the spring is present, and is much smaller than the force of the drive generator compared to the prior art. That is, the force of the spring in the present invention is assisted by the magnetic force to return, and the force of the spring is smaller than the force required to drive the generator to generate electricity. Therefore, the restoring force is obviously reduced, and the beneficial effect of labor saving is achieved.

According to another aspect of the present invention, there is further provided a power generation method of a power generation apparatus, wherein the power generation method includes the steps of:

(1) A magnetic attraction device 40 is attracted to a brake 30 through magnetic attraction; and

(2) A driving bracket 10 is driven to be separated from the brake 30, wherein a magnetic attraction device 40 moves synchronously with the driving bracket 10, and the magnetic field of the brake 30 is changed by the magnetic attraction device 40 in the moving process, so that a coil 200 positioned on the brake 30 generates induced electric energy.

The power generation method of the power generation device further comprises the steps of:

(3) When the external force is released, the magnetic attraction means 40 is attracted to the stopper 30 by the magnetic attraction action, so that the driving bracket is reset to the initial position.

In the step (2) of the power generation method of the power generation device, further comprising the steps of: driving an accumulator 20 such that the accumulator 20 is deformed and elastic potential energy is stored by the accumulator 20; when the elastic potential energy is greater than the magnetic attraction force, the energy accumulator 20 suddenly releases the elastic potential energy, and the energy accumulator 20 drives the driving bracket 10 to move and drives the magnetic attraction device 40 to break away from the attraction of the brake 30.

In the above power generation method of the power generation device, the driving bracket 10 includes a pivot end and a driving end integrally extending from the pivot end, wherein the magnetic attraction device 40 is disposed at the driving end, the pivot end of the driving bracket has a movable pivot, and when the energy accumulator drives the driving bracket to move, the driving bracket rotates based on the movable pivot. The rotation angle of the driving bracket 10 is less than or equal to 45 degrees.

Referring to fig. 14 to 16 of the drawings, another alternative embodiment of a driving apparatus 100B according to the above-described third preferred embodiment of the present invention is illustrated in the following description. The driving device 100B further includes a magnetic focusing unit 60B, where the magnetic focusing unit 60B is disposed on the magnetic attraction device 40B, and the magnetic focusing unit 60B is used to focus the magnetic induction line on the other side of the magnetic attraction device 40B, so that the electric energy induced by the coil 200B is stronger.

In detail, the magnetic focusing unit 60B is disposed at the magnetic attraction unit 41B, and the magnetic focusing unit 60B is spaced apart from the driving unit 42B by the magnetic attraction unit 41B, whereby the magnetic focusing unit 60B focuses the magnetic induction lines of the magnetic attraction unit 41B. Preferably, in the preferred embodiment of the present invention, the magnetic focusing unit 60B may be, but is not limited to, a metal or alloy having a magnetic focusing effect such as iron, cobalt, nickel, etc. It should be noted that in the preferred embodiment of the present invention, the length of the magnetism collecting unit 60B is shorter than the length of the driving unit 42B of the magnetic attraction means 40B, and the magnetism collecting unit 60B is not in contact with the stopper 30B when the magnetic attraction means 40B rotates.

Therefore, in the present embodiment, the driving unit 42B is in contact with the brake 30B, and the magnetism collecting unit 60B is not in contact with the brake 30B, so that the non-contact design makes it possible to prevent noise during operation and resetting and significantly reduce the force required for driving the power generation device. Because the invention only needs a spring with lighter force to reset during the reset operation, the force of the reset spring does not need to be larger than the driving force of the generator as in the prior art.

When the stroke of the driving unit 42B to separate the brake is less than 0.5 mm, the driving unit 42B and the brake 30B are still in a range of strong magnetic force. When the external force is released, the driving unit 42B and the brake 30B automatically return to normal state under the action of magnetic force, so that the invention has the function of automatic reset and can save a reset spring.

Referring to fig. 17 to 19 of drawings of the present specification, a power generation device according to a fourth preferred embodiment of the present invention is explained in the following description. Compared with the power generation device in the prior art, the power generation device is labor-saving when driven to generate power, and can automatically reset after driving to generate power. The principle of this preferred embodiment of the invention is the same as the preferred embodiment described above, except that the aforesaid embodiment is such that one end of the brake interacts with the magnetic attraction means, whereas in this embodiment both ends of the brake are acted upon by the magnetic attraction means.

The power generation device comprises at least one magnetic attraction unit 10C, at least one magnetic conduction device 20C, a brake 30C and at least one coil 40C, wherein the magnetic conduction device 20C is arranged on the magnetic attraction unit 10C, and the magnetic force of the magnetic attraction unit 10C is conducted by the magnetic conduction device 20C. The magnetic conduction device 20C is conductively connected to the magnetic attraction unit 10C, for example, the magnetic conduction device 20C is disposed on the N pole side and/or the S pole side of the magnetic attraction unit 10C, whereby the magnetic conduction device 20C conducts magnetism of the magnetic attraction unit 10C, that is, the magnetic attraction unit 10C can magnetically attract the brake 30C through the magnetic conduction device 20C. It should be noted that, in the preferred embodiment of the present invention, the brake 30C is the same as the preferred embodiment described above, and will not be described herein.

The coil 40C is implemented as an induced power generation site of the power generation device of the present invention, wherein the coil 40C is provided to the brake 30C. By changing the magnetic field change at the position of the brake 30C, the magnetic field in the brake 30C is changed in strength to cause the generation of induced electric energy in the coil 40C. It will be appreciated that the coil 40C moves synchronously with the brake 30C; or in the case of the coil 40C being stationary, the brake 30C moves, such as rotates, oscillates, within the coil 40C, so that in this preferred embodiment of the invention, the magnetic field strength at the location of the coil 40C can be varied by driving the brake 30C in a moving manner, thereby generating induced electrical energy from the coil 40C; and/or driving the magnetic conduction device 20C and the magnetic attraction device 10C to move, so that the magnetic field at the position of the coil 40C is changed, and the coil 40C generates induced electric energy. Briefly, in the preferred embodiment of the present invention, the coil 40C is caused to generate induced electrical energy by driving the relative positional relationship between the brake 30C and the magnetic conductive device 20C. The brake 30C and the magnetic unit 10C are relatively moved, that is, if the magnetic unit 10C is fixed, the brake 30C can swing; and if the stopper 30C is fixed, the magnetic unit 10C may swing to apply a magnetic force to the stopper 30C.

Preferably, in the preferred embodiment of the present invention, the number of the magnetic conductive devices 20C is two, wherein the magnetic conductive devices 20C are disposed at both ends of the magnetic attraction unit 10C, that is, one of the magnetic conductive devices 20C is located at the N-end of the magnetic attraction unit 10C, and the other magnetic conductive device 20C is located at the S-end of the magnetic attraction unit 10C. In other words, one of the magnetic conduction devices 20C is disposed at each end of the magnetic attraction unit 10C, and a magnetic conduction space 201C is defined by the magnetic conduction devices 20C, wherein the brake 30C is located in the magnetic conduction space 201C between the two magnetic conduction devices 20C.

Preferably, in the preferred embodiment of the present invention, the power generation means causes the coil 40C to generate the induced electric energy in such a manner as to rotate the brake 30C. A braking gap 202C is further disposed between the magnetic conductive devices 20C, wherein the two ends of the brake 30C extend outwards from the braking gap 202C of the magnetic conductive devices 20C. The brake 30C is driven to move in the magnetic space 201C between the magnetic devices 20C and is restricted to the magnetic gap 202C of the magnetic devices 20C. In short, when the brake 30C moves, both ends of the brake 30C are restricted by the magnetic conductive device 20C to prevent the brake 30C from transitionally moving, preventing an excessive distance between the brake 30C and the magnetic conductive device 20C from affecting the resetting of the brake 30C.

The brake 30C has a rotation axis L, wherein the brake 30C rotates around the rotation axis L when being driven by force. The brake 30C is pivotably provided to the housing of the power generation device, wherein when the end of the brake 30C is applied, the brake 30C rotates about the rotation axis L, and the coil 40C generates induced electric energy. Preferably, the rotation shaft L is located at a middle position of the brake 30C.

Each magnetic conduction device 20C includes a magnetic conduction main body 21C, a magnetism collecting unit 22C, and a driving unit 23C, wherein the magnetism collecting unit 22C and the driving unit 23C are disposed on the magnetic conduction main body 21C, the magnetic conduction main body 21C is disposed on the magnetic attraction unit 10C, and the magnetism collecting unit 22C and the driving unit 23C are disposed at opposite ends of the magnetic conduction main body 21C. It should be noted that, the two magnetic conduction devices 20C are disposed to cross each other, that is, the magnetic focusing unit 22C of one magnetic conduction device 20C corresponds to the driving unit 23C of the other magnetic conduction device 20C through the magnetic conduction gap 202C; the driving unit 23C of one magnetic conduction device 20C corresponds to the magnetism collecting unit 22C of the other magnetic conduction device 20C through the magnetic conduction gap 202C.

Preferably, the driving unit 23C integrally extends from the magnetically conductive body 21C, and the magnetic force of the magnetically conductive body 21C is conducted by the driving unit 23C, that is, the driving unit 23C adsorbs the brake 30C. The magnetic focusing unit 22C is located on the other side opposite to the driving unit 23C, wherein the magnetic focusing unit 22C functions the same as the magnetic focusing unit in the above preferred embodiment, except that in the preferred embodiment of the present invention, the magnetic focusing unit is also used to reduce the magnetic force conducted to the brake 30C. Preferably, in the preferred embodiment of the present invention, the magnetic focusing unit 22C is provided with a non-magnetically conductive medium, such as plastic, non-magnetically conductive metal, air, rubber.

The brake 30C has a braking position and at least one driving position, and in a normal state, i.e. when the power generation device is not driven to generate power, the brake 30C is located at the braking position and is absorbed by the magnetic conduction device 20C, wherein the brake 30C is absorbed by the driving unit 23C of the magnetic conduction device 20C, it can be understood that two ends of the brake 30C are respectively absorbed by the driving units 23C of the two magnetic conduction devices 20C. When the brake 30C is forced to be driven to the driving position at the braking position, the brake 30C rotates based on the rotating shaft L, wherein the brake 30C overcomes the magnetic adsorption force of the magnetic conduction device 20C under the action of external force, wherein the end part of the brake 30C moves towards the magnetism collecting unit 22C, and in the process, the coil 40C moves synchronously with the brake 30C; or the coil 40C swings the brake 30C while being kept stationary, and induced power is generated by the coil 40C.

When the external force is removed, the driving unit 23C of the magnetic conduction device 20C attracts the brake 30C by magnetic attraction, and the force conducted from the magnetic conduction body 21C to the brake 30C is reduced due to the magnetism collecting unit 22C. Therefore, the brake 30C returns from the driving position to the braking position, i.e., the initial state, under the magnetic attraction force of the driving unit 23C of the magnetic conductive device 20C. It should be noted that, when the external force is lost, the coil 40C can generate the induced electric energy again due to the change of the position of the brake 30C during the return of the brake 30C to the initial position.

It should be noted that, initially, the two ends of the brake 30C are respectively attracted to the driving units 23C of the upper and lower magnetic conductive devices 20C, and the brake 30C is a saturated magnetic field, so that no current is induced in the coil. When the external force drives the brake 30C to swing in a pivoting manner, the brake 30C pivots, wherein the two ends of the brake 30C are separated from the magnetic attraction of the driving unit 23C and are close to the magnetism collecting units 22C, respectively. In this process, the magnetic field in the brake 30C is changed in strength to cause induced electric energy to be generated in the coil 40C.

Although the brake 30C is separated from the driving unit 23C, there is still a strong attraction force to the brake 30C due to the strong magnetic force of the driving unit 23C in a certain stroke range, for example, in a distance of 0.1-0.5 mm. At this time, if the applied external force is released, the brake 30C automatically returns to the original position by the magnetic force of the driving unit 23C, thereby automatically resetting to the initial state.

In particular, when the magnetic force provided by the magnetic attraction unit 10C is weak and the distance of the brake 30C from the driving unit 23C is long, the driving unit 23C may not provide enough magnetic force to automatically reset the brake 30C, and a spring with a smaller elastic force than the force for driving the brake 30C to separate from the driving unit 23C may be used for assisting the reset. The power generation device further includes at least one reset device 50C, wherein the reset device 50C is used to assist in resetting the brake 30C. The resetting device 50C is drivingly connected to the brake 30C, and when the brake 30C is driven to move, an assist force for urging the brake 30C to be reset is provided by the resetting device 50C. It should be noted that, in the preferred embodiment of the present invention, the auxiliary restoring force provided by the restoring means 50C to the brake 30C is smaller than the force of the power generation means when the power generation means is driven by pressing, that is, smaller than the magnetic attraction force between the brake 30C and the driving unit 23C, thereby achieving a restoring effect of saving labor.

Referring to fig. 20 to 22 of drawings of the present specification, a power generation device according to a fifth preferred embodiment of the present invention is explained in the following description. The power generation device comprises at least one magnetic attraction unit 10D, a driving bracket 20D, a brake 30D and at least one coil 40D, wherein the at least one magnetic attraction unit 10D is arranged on the driving bracket 20D, and the driving bracket 20D can be driven by external force and drives the magnetic attraction unit 10D to synchronously move. The coil 40D is provided to the actuator 30D, and when the magnetic field strength of the magnetic attraction device 10D is changed, induced electric energy is generated by the coil 40D.

The driving bracket 20D of the power generation device has a braking position and a driving position, and the driving bracket 20D is located at the braking position in a normal state, that is, when the power generation device is not driven to generate power, wherein the brake 30D is attracted by the magnetic attraction unit 10D through the driving bracket 20D. When the driving bracket 20D is forced to be driven at the braking position, the driving bracket 20D rotates based on a rotation axis L, wherein a magnetic attraction force between the brake 30D and the driving bracket 20D is overcome by an external force, so that the brake 30D is separated from the driving bracket 20D, and the magnetic density passing through the brake 30D is changed due to a change in the position of the magnetic attraction unit 10D and the brake 30D is separated from the driving bracket 20D, so that a magnetic field at the positions of the brake 30D and the coil 40D is changed, and the coil 40D generates induced electric energy.

The driving bracket 20D includes a driving arm 21D and a driving portion 22D, wherein the driving portion 22D is linked with the driving arm 21D, and the driving portion 22D is driven by the driving arm 21D to move. The driving arm 21D has a driving end 211D and a pivoting end 212D integrally extending from the driving end 211D, wherein the driving portion 22D is provided at the pivoting end 212D of the driving arm 21D. It should be noted that, in the preferred embodiment of the present invention, the driving portion 22D of the driving bracket 20D is made of a magnetically conductive material, wherein the magnetic attraction unit 10D is attracted to the driving portion 22D, and the magnetic attraction force of the magnetic attraction unit 10D is conducted by the driving portion 22D. The drive bracket 20D further comprises at least one pivot axis 23D, wherein the drive bracket 20D is rotatable along the pivot axis 23D. Preferably, the pivot shaft 23D is provided at an end of the driving arm 21D or at a connection position of the driving arm 21D and the driving portion 22D. It will be appreciated that the location of the pivot axis 23D is not limited herein.

It should be noted that in this preferred embodiment of the present invention, the brake 30D is identical in structure and function to the brake of the preferred embodiment described above. It will be appreciated that the brake 30D may be fixed, or movably fixed, to the housing of the power generation device. The driving bracket 20D is driven by an external force, the driving bracket 20D drives the magnetic attraction unit 10D, and changes the density of the magnetic field at the position of the coil 40D, so that the coil 40D generates induced electric energy.

In an initial state, the driving bracket 20D of the power generation device is located at the braking position, wherein the brake 30D is attracted to the driving portion 22D of the driving bracket 20D, or the driving bracket 20D is attracted to the brake 30D by the magnetic attraction force.

The power generation device further comprises an energy storage device 50D, wherein the energy storage device 50D is drivingly connected with the brake 30D, and when the driving bracket 20D is rotated by an external force, the brake 30D pulls the energy storage device 50D by the brake 30D and stores potential energy by the energy storage device 50D before the brake 30D is separated from the driving bracket 20D. During the separation of the brake 30D from the driving bracket 20D against the magnetic attraction force, the energy storage device 50D releases the stored potential energy, and the brake 30D is pulled by the energy storage device 50D to move in the opposite direction, so that the brake 30D is rapidly separated from the driving bracket 20D.

It will be appreciated that the energy storage device 50D is disposed on the opposite side of the drive portion 22D, or at an end of the brake 30D remote from the drive portion 22D; wherein the energy storage device 50D is connected to the brake 30D. Preferably, in this preferred embodiment of the invention, the energy storage means 50D is embodied as a spring. It should be noted that, in other alternative embodiments of the present invention, the energy storage device 50D may also be implemented as an elastic cord, a leather cord, a torsion spring, a spring plate, or the like, which has a function of storing elastic potential energy. It is worth mentioning that in this preferred embodiment of the invention the specific position of the energy storage means in connection with said brake 30D is not limited.

It should be noted that, when an external force is applied to the driving arm 21D, the driving arm 21D moves in a manner of interlocking with the driving portion 22D, the driving portion 22D moves in a direction of separating from the brake 30D, and the brake 30D moves along with the driving portion 22D under the action of the magnetic force and stretches the energy storage device 50D to store elastic potential energy. When the driving part 22D continues to move in a direction away from the brake 30D, after the magnetic force sucked between the brake 30D and the driving part 22D is smaller than the elastic force stored by the accumulator 50D, the accumulator 50D rapidly pulls the brake 30D back, and the driving part 22D is separated from the brake 30D at a high speed, so that the driving part 22D and the brake 30D can be separated instantaneously, and a strong elastic potential energy is generated in the coil.

After the driving part 22D is separated from the stopper 30D, the driving part 22D is separated from the stopper 30D by a small distance, and the two are still in the range of the attractive force of the magnet. Therefore, when the external force for driving the driving arm 21D is released, the driving portion 22D and the brake 30D can be automatically attracted together again under the action of the magnetic force, thereby completing the automatic resetting function.

In particular, when the magnetic force provided by the magnetic attraction unit 10D is weak and the distance of the brake 30D from the driving unit 22D is long, the driving unit 22D may provide insufficient magnetic force to enable the brake 30D to automatically reset, and a spring with a smaller elastic force than the force for driving the driving bracket 20D to separate from the brake 30D may be used for assisting the resetting. The power generation device further includes at least one reset device 60D, wherein the reset device 50D is used to assist in resetting the drive bracket 20D. The reset device 60D is drivingly connected to the drive bracket 20D, and when the drive bracket 20D is driven to move, an auxiliary force for causing the drive bracket 20D to reset is provided by the reset device 60D. It should be noted that, in the preferred embodiment of the present invention, the auxiliary restoring force provided by the restoring means 50D to the driving bracket 20D is smaller than the force generated when the power generating means is driven by pressing, that is, smaller than the magnetic attraction force between the brake 30D and the driving bracket 20D.

It should be noted that, when the driving portion 22D is separated from the brake 30D by a large distance, the traction by the magnetic force is insufficient to automatically reset the driving portion and the brake, and the driving force provided by the reset device 60D is smaller than the driving force for driving the generator. Preferably, the force required for resetting is less than 1/2 of the force driving the drive bracket 20D. The reset spring can be arranged at any position capable of driving the power generation device to reset, and the invention does not limit the position.

(1) In the initial state, the magnetic attraction acts on a magnetic attraction device 40 and a brake 10 to be attracted together;

(2) Driving a driving bracket 10 to separate the brake 30 from the magnetic attraction device 40 and generate induced electric energy in the separation process; and

(3) When the distance separating the brake 30 from the driving bracket 10 is within a certain range, the driving bracket 10 is attracted to the brake 30 by the magnetic force to be restored to the original state after the external force is released.

In the above-described step (2) of the resetting method of the present invention, the brake 30 or the driving bracket 10 is sleeved with a coil, and induced electric energy is generated from the coil in a process of separating the brake 30 from the magnetic attraction means 40. In the above-described step (2) of the resetting method of the present invention, when the brake 30 is separated from the magnetic attraction means 40, the driving bracket 10 drives a generator 200, and the generator 200 generates induced power.

(a) Driving an energy accumulator 20 to deform, and storing elastic potential energy by the energy accumulator 20, wherein the energy accumulator 20 is connected with a driving bracket 10, and the driving bracket 10 and a brake 30 are mutually adsorbed through magnetic attraction in an initial state;

(b) Releasing elastic potential energy from the accumulator 30 to the driving bracket 10 when the elastic potential energy of the accumulator 20 is enough to overcome the magnetic force between the brake 30 and the driving bracket 10, the brake 30 and the driving bracket 10 being separated, and generating induced electric energy from a coil provided to the brake 30 during the separation; and

(c) When the external force is released, the driving bracket 10 and the brake 30 are attracted to each other under the action of magnetic force, and return to the initial position.

In the power generation method of the present invention, in the step (c), the driving bracket and the brake 30 can be automatically reset under the action of magnetic force in a certain range of travel, so that the power generation and automatic reset functions are realized by using the magnetic force of the magnetic attraction device in one cycle operation of the power generation device. For example, in the stroke of 0.2-0.5 mm, the magnetic force of the same magnetic device can be used for realizing automatic resetting, and when the magnetic force exceeds the range, other mechanical devices can be used for saving labor for resetting.

In the power generation method of the present invention, wherein in the step c, after the mechanical force is released, a force required for the return between the driving bracket and the brake 30 is smaller than a force required for the separation of the driving bracket from the brake 30.

According to another aspect of the present invention, there is further provided a power generation method of a power generation apparatus, wherein the power generation method comprises the steps of:

In the power generation method of the power generation device, an external force drives a driving bracket, wherein the magnetic attraction device is arranged on the driving bracket and rotates along with the driving bracket so as to change the magnetic field intensity of the coil position. In step c, when the distance between the magnetic attraction device and the brake exceeds the distance required by the automatic reset of the magnetic force, the driving support is assisted to reset by the thrust of a resetting device, and the resetting force of the resetting device is smaller than the force required by the separation of the brake and the magnetic attraction device.

In the step b of the power generation method of the power generation device, a magnetic focusing part is provided at the other side of the brake, and after the brake is separated from the magnetic attraction device, the brake is close to the magnetic focusing part so as to strengthen the magnetic field intensity in the brake. The brake and the magnetism gathering part can have two contact relations, namely a close or micro contact relation; the proximity indicates that a certain gap exists between the brake and the magnetism gathering part, or a non-magnetic medium exists between the brake and the magnetism gathering part, including but not limited to air, plastics, rubber, ceramics, stainless steel and the like. And "micro-contact" between the stopper and the magnetism collecting part means that the magnetic force obtained by the stopper from the magnetism collecting part is smaller than the magnetic force obtained by the stopper from the driving unit, in other words, the area of contact of the stopper with the magnetism collecting part is smaller, and thus the obtained magnetic force is also smaller.

In the power generation method II of the above power generation device of the invention, the time required for the brake and the magnetic attraction device to separate from each other from the start to the maximum stroke position is less than 1/4 second; the reset force is less than or equal to 1/2 of the magnetic attraction force.

A wireless controller according to a preferred embodiment of the present invention is illustrated in the following description with reference to fig. 23 and 24 of the drawings accompanying the present invention. The wireless controller comprises a power generation device 1000 and at least one radio frequency communication circuit 2000 electrically connected to the power generation device 1000, wherein the radio frequency communication circuit 2000 is arranged on the power generation device 1000, when the power generation device 1000 is driven to generate power, the power generated by the power generation device 1000 is provided for the radio frequency communication circuit 2000, and the radio frequency communication circuit 2000 sends out wireless communication signals.

It should be noted that the power generation device 1000 may be implemented as any of the above-described power generation devices according to the preferred embodiments, wherein the radio frequency communication circuit 2000 is built into the power generation device 1000, and wherein the radio frequency communication circuit 2000 is electrically connected to a coil in the power generation device 1000.

According to the disclosure of the power generation device, the invention can be widely applied to various power generation products to form a power generation wireless controller, such as a power generation wireless switch, a power generation wireless doorbell, wireless security equipment, calling equipment, a sensor, a wireless control device and the like, and is used for replacing batteries to provide high-efficiency driving power for the wireless equipment, so that the products have lighter operation handfeel and quieter experience sense.

In particular, when the power generation device disclosed by the invention is applied to wireless products, such as self-generating wireless switch application, in order to achieve a very good use effect and have a long control distance, the invention needs to be designed in a certain optimization way.

The power generation device 1000 can generate 50-300uJ of electric energy under the condition of very saving power, and how to send wireless signals farther and more reliably by utilizing the tiny electric energy is the problem to be solved by the invention.

Generally, the problem that the signals interfere with each other when the radio signals are transmitted at the same frequency is solved, so that the communication distance of the radio equipment is seriously reduced, and even the radio control is failed; therefore, in order not to affect the reliability of wireless communication, the wireless switch in the prior art generally adopts a frequency hopping mode to transmit signals in multiple channels, but in a self-generating device, tiny electric energy generated by the generating device is insufficient to support a radio frequency circuit to perform frequency hopping communication;

therefore, if there are many radio switches of the same frequency provided in one space, a situation of mutual interference occurs, so that control fails. In the preferred embodiment of the present invention, when the power generation device 1000 generates power, in order to make full use of the power, the length of data to be wirelessly transmitted is controlled to be within 15 bytes to reduce the time for transmitting signals, and the shorter the time for transmitting data is, the better. Preferably, the communication circuit controls the time of one wireless radio frequency communication to less than 1.5 ms when the power generation device 1000 starts to supply power.

As shown in fig. 24, the time for transmitting the primary signal by the communication circuit is controlled to be less than 1.5 ms, so that the probability of signal collision between the switches when a plurality of wireless switches are operated at the same time can be greatly reduced, and the reliability of the self-generating wireless signal is ensured.

In particular, it is shown by test results that when the wireless switch is pressed by hand (i.e., the power generation device 1000), the time required to complete the pressing and resetting operation at the fastest time is about 100 milliseconds during the mechanical operation of the hand. If the time for the wireless switch to communicate once is set to 100 ms, when two wireless switches are simultaneously pressed, the two wireless switches simultaneously transmit the same frequency signals to interfere with each other, and if the time for the wireless switch to communicate once is set to 50 ms, the probability that the signals generated by the two switches collide with each other is reduced, but the signals may still collide. If the communication time of the wireless switch is controlled to be within 1.5 ms, it is theoretically possible to allow 30 or so wireless switches transmitting signals at the same frequency to be simultaneously pressed without interfering with each other when the plurality of indoor switches are simultaneously operated, and 30 switches are sufficiently used in living places such as home and hotel. If a plurality of switches are also arranged in other households, the radio frequency power of the present invention is limited to less than 12dB, and is generally preferably between 3 and 10dB, and the distance of indoor wireless control is about 10 to 20 meters, so that the communication of the wireless switches of other households is not affected.

Preferably, when the power generation device 1000 generates the induced electric energy, the induced electric energy is transmitted to the radio frequency circuit, so that the radio frequency circuit 2000 can complete the radio frequency communication task at least once in a time less than or equal to 1.5 ms, so that at least two wireless controllers transmitting signals with the same frequency can not generate a signal collision condition when being pressed and reset simultaneously, and although the two wireless switches with the same frequency are operated simultaneously, according to the technical scheme of the invention, the control signals of the two wireless switches can be accurately received by respective terminal devices, thereby expanding the channel of the same frequency communication.

Therefore, the invention solves the problem of the same-frequency interference of the wireless switch by utilizing the remarkable characteristic disclosed by the invention, and realizes conflict-free communication among multiple self-generating wireless switches under the condition of not increasing hardware cost and spectrum resources, thereby having remarkable economic benefit.

According to another aspect of the present invention, there is further provided a method for operating a wireless controller, wherein the method for operating a wireless controller includes the steps of:

and III, setting the radio frequency communication circuit to complete radio frequency communication at least once in a time less than or equal to 1.5 milliseconds when the coil generates induced electric energy, so that signal collision does not occur when at least two radio controllers with the same frequency are pressed and reset simultaneously. When the brake is separated from the magnetic attraction device, the force smaller than the magnetic attraction effect is used for driving the brake to reset with the magnetic attraction device, so that the force required by the reset operation is reduced. It is worth mentioning that the restoring force for driving the brake to restore to the original position of the magnetic attraction device is less than or equal to 1/2 of the magnetic attraction force. The magnetic attraction device comprises a magnetic attraction unit, a driving unit and a magnetic gathering unit, wherein the magnetic gathering unit is arranged on the magnetic attraction unit, and the magnetic gathering unit is oppositely arranged with the driving unit at intervals through the magnetic attraction unit so as to gather magnetic induction lines of the magnetic attraction unit.

It will be appreciated by persons skilled in the art that the embodiments of the invention described above and shown in the drawings are by way of example only and are not limiting. The objects of the present invention have been fully and effectively achieved. The functional and structural principles of the present invention have been shown and described in the examples and embodiments of the invention may be modified or practiced without departing from the principles described.
