Description

Technical Field

[0001] This invention relates to the field of magnetic control and energy conversion, specifically to a variable magnetic device. Background Technology

[0002] Magnets, due to their property of "like poles repel and unlike poles attract," are widely used in various power devices and sensors. However, traditional magnetic applications are mostly limited to fixed attraction or repulsion modes, making it difficult to achieve dynamic, continuous, and reversible adjustment of magnetic force. For example, in devices that attempt to use magnetic repulsion as a power source, the magnitude and direction of the magnetic force are usually fixed and cannot be adjusted according to operating conditions, resulting in low energy utilization and limited application range.

[0003] Publication No. CN113130166A, Publication Date 2021.07.16, discloses a device with variable magnetic force, including a fixed box, an upper magnet and a lower magnet are arranged inside the fixed box, two blocking doors are arranged between the upper magnet and the lower magnet, the two blocking doors are slidably arranged on a shaft, and the shaft is connected to a fixed frame.

[0004] In the prior art, including the aforementioned application, a sliding iron plate barrier is installed between two magnets with opposite poles to achieve switching between three basic states: repulsion, attraction, and force balance. However, the adjustment method is a simple "on" or "off," which cannot achieve continuous and precise adjustment of the magnetic force, let alone multiple preset magnetic force change modes. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a variable magnetic force device.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows:

[0007] A variable magnetic force device, comprising:

[0008] A sliding first magnet and a fixed second magnet, with their same magnetic poles facing each other;

[0009] A stopper is provided between the first magnet and the second magnet, and at least one such stopper is provided.

[0010] The drive mechanism, which is connected to the stopper, drives the stopper to move between the first magnet and the second magnet, so as to continuously and reversibly change the magnetic force between the first magnet and the second magnet, so that the first magnet makes a reciprocating linear motion.

[0011] A power conversion mechanism is connected to the first magnet to convert the reciprocating linear motion of the first magnet into the rotational motion of the output end of the power conversion mechanism.

[0012] Preferably, the blocker is an iron blocker made of pure iron.

[0013] Preferably, the thickness of the iron blocker is directly proportional to the repulsive force between the first magnet and the second magnet in the unobstructed state.

[0014] Preferably, when the thickness of the iron blocker is set to be less than the standard thickness, when the iron blocker is driven to the maximum magnetic shielding state, there is still a repulsive force between the first magnet and the second magnet.

[0015] Preferably, the blocker is a magnetic blocker composed of a C3 iron sheet and C1 and C2 auxiliary magnets attached to both sides of the C3 iron sheet, wherein the C1 and C2 auxiliary magnets have the same magnetic poles as the first magnet and the second magnet, respectively.

[0016] Preferably, the magnetic strength of both the C1 and C2 auxiliary magnets is lower than that of the first and second magnets.

[0017] Preferably, the overall magnetization intensity of the magnetic blocking device is adjusted to change the adjustable range of the repulsive force between the first magnet and the second magnet.

[0018] Preferably, the power conversion mechanism includes a crankshaft that is rotatably disposed and a connecting rod that is hinged between the crankshaft and the first magnet.

[0019] Preferably, the driving mechanism includes a driving rod and a spring-loaded shaft, one end of which is connected to the driving rod for transmission, and the other end of which is fixedly connected to a first magnet.

[0020] Preferably, both the first magnet and the second magnet are covered with a magnet shell made of a non-magnetic material.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] This invention uses two driving mechanisms to control the relative movement of two symmetrically arranged stoppers, allowing the opening degree of the two stoppers to continuously vary between 0% and 100%. This enables continuous and reversible alteration of the magnetic force, driving a first magnet to reciprocate linearly. A power conversion mechanism, connected to the first magnet, converts this reciprocating linear motion into rotational motion at its output, providing power to subsequent equipment. The magnetic force varies according to different modes, using the first and second magnets as power sources. The driving mechanism controls the sliding adjustment of the stoppers to regulate the magnetic force, with the reciprocating linear motion of the first magnet serving as an intermediate carrier. Finally, the power conversion mechanism outputs rotational power. By adjusting the opening degree of the stoppers, multiple magnetic force modes can be achieved, meeting power output requirements in different scenarios. This effectively improves the adaptability and practicality of the device. Furthermore, it directly utilizes magnetic energy, effectively avoiding energy conversion losses. Power can be output in both directions of the first magnet's reciprocating motion, effectively improving energy utilization. The mechanical structure is simple, and maintenance costs are low.

[0032] It is readily understood that, based on the technical solution of this invention, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of the invention. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this invention and should not be considered as the entirety of the invention or as limitations or restrictions on the technical solution of this invention.

[0033] like Figure 1-7 As shown, a variable magnetic force device includes:

[0034] A sliding first magnet 1 and a fixed second magnet 2 are arranged with their magnetic poles facing each other.

[0035] At least one blocker is provided between the first magnet 1 and the second magnet 2;

[0036] The drive mechanism connected to the stopper drives the stopper to move between the first magnet 1 and the second magnet 2, so as to continuously and reversibly change the magnetic force between the first magnet 1 and the second magnet 2, so that the first magnet 1 makes a reciprocating linear motion.

[0037] A power conversion mechanism is connected to the first magnet 1 to convert the reciprocating linear motion of the first magnet 1 into the rotational motion of the output end of the power conversion mechanism.

[0038] Specifically, such as Figure 1 As shown, the second magnet 2 is fixedly mounted at the end of the second fixed frame 12, and the other end of the second fixed frame 12 is fixed to the large fixed frame 13 near the top by a fixing screw 24. The first magnet 1 is slidably mounted in the piston cylinder 15, and the piston cylinder 15 is fixedly mounted at one end of the third fixed frame 16. The other end of the third fixed frame 16 is fixed to the large fixed frame 13, and the large fixed frame 13 is mounted on the fixed base 14. The first magnet 1 and the second magnet 2 are coaxially arranged, and their corresponding magnetic poles are arranged opposite each other, so that the two magnets generate a repulsive force in their natural state.

[0039] Furthermore, the blocker is moved and positioned between the first magnet 1 and the second magnet 2 along a direction perpendicular to the central axis of the first magnet 1. The drive mechanism is fixedly mounted on the second magnet 2, and the output end of the drive mechanism is connected to the blocker. The blocker is driven to move between the first magnet 1 and the second magnet 2 through the drive mechanism, thereby changing the degree of blocking of the repulsive magnetic force, thereby realizing the controllable adjustment of the magnetic force.

[0040] It should be noted that the drive mechanism can employ any technique known to those skilled in the art, such as a mechanical linkage, an electric push rod, or a stepper motor. One, two, or more stoppers can be provided, sufficient to block the repulsive magnetic force between the first magnet 1 and the second magnet 2 to meet usage requirements. Figure 1 As shown, a detailed explanation will be given using two symmetrically arranged blocks as an example:

[0041] Two symmetrically arranged stoppers are controlled by two drive mechanisms to move relative to each other, so that the opening degree of the two stoppers can be continuously changed between 0% and 100%, thereby realizing continuous and reversible change of magnetic force. The magnetic force drives the first magnet 1 to perform reciprocating linear motion, and the reciprocating linear motion of the first magnet 1 is converted into the rotational motion of the output end of the power conversion mechanism through the power conversion mechanism connected to the first magnet 1, and provides power output for subsequent equipment.

[0042] The following will briefly introduce the opening and closing modes of the two blockers:

[0043] Mode 1: The two blocks completely exit the working area between the first magnet 1 and the second magnet 2, without any obstruction, achieving 100% full opening.

[0044] Mode 2: The two blocking devices are completely closed and enter between the first magnet 1 and the second magnet 2, completely blocking the magnetic pole action surface and achieving 100% complete closure.

[0045] Mode 3: Two blocking parts are inserted between the first magnet 1 and the second magnet 2, blocking 50% of the magnetic pole action surface, and the blocked area and the unblocked area are evenly distributed.

[0046] Mode 4: The two blocks open from 50% to 60% to 70% to 80% to 90% to 100%, and the blocks gradually move out from between the first magnet 1 and the second magnet 2 from a half-blocking state, with the blocking area continuously decreasing from 50% to 0%.

[0047] Mode 5: The two blocks are closed from 50% to 60% to 70% to 80% to 90% to 100%. The blocks are gradually inserted between the first magnet 1 and the second magnet 2 from a half-blocking state, and the blocking area continues to increase from 50% to 100%.

[0048] Mode 6: The two blocks open from 1% to 10% to 20% to 30% to 40% to 50%, and the blocks gradually move out from between the first magnet 1 and the second magnet 2 from near complete closure, with the blocking area continuously decreasing from 99% to 50%.

[0049] Mode 7: The two blocks close from 1% to 10% to 20% to 30% to 40% to 50%, and the blocks gradually insert between the first magnet 1 and the second magnet 2 from almost fully open, with the blocking area continuously increasing from 1% to 50%.

[0050] The magnetic force changes according to different modes. The first magnet 1 and the second magnet 2 with the same name are used as the power source. The magnetic force is adjusted by controlling the sliding of the stopper through the drive mechanism. The reciprocating linear motion of the first magnet 1 is used as the intermediate carrier. Finally, the rotational power is output through the power conversion mechanism. By controlling the opening and closing degree of the stopper, multiple magnetic force modes can be realized, thereby meeting the power output requirements in different scenarios. This effectively improves the adaptability and practicality of the device. It directly uses magnetic energy to drive the device, effectively avoiding energy conversion loss. The bidirectional reciprocating motion of the first magnet 1 can output power, effectively improving energy utilization. Moreover, the mechanical structure is simple and the maintenance cost is low.

[0051] Mode 8: The two blocking devices are completely closed and enter between the first magnet 1 and the second magnet 2, which completely blocks the magnetic pole action surface to achieve 100% complete closure. The magnetic force of the magnetic blocking device 25 and the thickness of the iron blocking device 4 can be adjusted up and down.

[0052] It should be noted that the power conversion mechanism can be any technique known to those skilled in the art, such as a crankshaft connecting rod mechanism, a gear and rack mechanism, or a hydraulic transmission mechanism. The crankshaft connecting rod mechanism will be described in detail below:

[0053] The power conversion mechanism includes a crankshaft 17 that is rotatably disposed and a connecting rod 18 that is hinged between the crankshaft 17 and the first magnet 1.

[0054] Specifically, such as Figure 1 As shown, the crankshaft 17 is rotatably mounted between the fifth fixed frame 23 and the fourth fixed frame 19. Both the fifth fixed frame 23 and the fourth fixed frame 19 are fixedly mounted on the large fixed frame 13. The crankshaft 17 is provided with a second ball bearing 22 and a first ball bearing 21 at its two ends, respectively. A flywheel 20 is mounted on one end of the crankshaft 17. The connecting rod 18 is hinged between the crankshaft 17 and the first magnet 1. The reciprocating linear motion of the first magnet 1 is transmitted to the crankshaft 17 through the connecting rod 18. The connecting rod 18 converts the linear thrust or pull of the first magnet 1 into the rotational torque of the crankshaft 17. The second ball bearing 22 and the first ball bearing 21 reduce the rotational resistance of the crankshaft 17, and the flywheel 20 enhances the stability of the rotational output. Finally, the efficient conversion of reciprocating linear motion into rotational motion is achieved, providing power output for subsequent equipment.

[0055] Furthermore, the degree of opening and closing of the stopper determines the magnitude of the magnetic force, which in turn determines the magnitude of the force pushing the first magnet 1. A large thrust results in a large acceleration of the first magnet 1, a large thrust of the connecting rod 18 on the crankshaft 17, a large output torque of the crankshaft 17, and a fast acceleration. A small thrust results in a small acceleration of the first magnet 1, a small thrust of the connecting rod 18 on the crankshaft 17, a small output torque of the crankshaft 17, and a slow acceleration. The opening and closing frequency of the stopper determines the reciprocating frequency of the first magnet 1. A high opening and closing frequency results in more work operations per unit time and a high average rotational speed of the crankshaft 17. A low opening and closing frequency results in fewer work operations per unit time and a low average rotational speed of the crankshaft 17. During initial startup, by controlling which direction the first magnet 1 moves first, the initial rotational direction of the crankshaft 17 can be determined. Since when the crankshaft 17 rotates to the point where the connecting rod 18 and the crankshaft arm are aligned... When the line is in position, no matter how much force is applied by the connecting rod 18, the crankshaft 17 cannot rotate. This position is called the dead point. Through the flywheel 20, once started, due to the inertia of the first magnet 1 and the flywheel 20, the crankshaft 17 can be pushed past the dead point position by the inertia brought by the mass and speed of the first magnet 1 and the flywheel 20, so that the crankshaft 17 can maintain rotation in the original direction. By periodically opening and closing the stopper, the crankshaft 17 can be accelerated from rest and the direction of rotation can be determined. Opening the stopper to the maximum and switching it quickly provides the maximum repulsive force, thereby outputting the maximum torque and power. By reducing the opening degree of the stopper or reducing the switching frequency, a smaller magnetic force is provided, so that the crankshaft 17 can maintain a lower speed. Utilizing the force balance characteristic of the stopper at 50% opening, the output magnetic force can be adjusted very precisely, thereby achieving fine adjustment of the crankshaft speed.

[0056] The stopper is an iron stopper 4 made of pure iron.

[0057] Specifically, such as Figures 2-4 As shown, when the blocker is an iron blocker 4 made of pure iron, when the iron blocker 4 is pushed between the first magnet 1 and the second magnet 2, the high permeability of the iron blocker 4 will short-circuit the magnetic field lines, causing the magnetic field lines to preferentially pass through the loop formed by the iron blocker 4. This greatly weakens the repulsive force between the first magnet 1 and the second magnet 2, and instead turns into a strong attraction between the first magnet 1 and the second magnet 2 to the iron blocker 4. Since the iron blocker 4 can only move relative to the first magnet 1 and the second magnet 2 in a direction perpendicular to the central axis of the first magnet 1 and the second magnet 2, according to Newton's third law, this attractive force will act on the first magnet 1 and the second magnet 2 simultaneously. Since the second magnet 2 is fixed, only the first magnet 1 moves when subjected to the attractive or repulsive force.

[0058] The following details the eight functions of the variable magnetic force technology that can be generated by the iron stopper 4:

[0059] The first capability: the two iron blocking devices 4 completely exit the working area between the first magnet 1 and the second magnet 2, without any obstruction, achieving 100% complete opening. The two magnets are magnetic poles of the same name, naturally repelling each other. When there is no obstruction, the repulsive force reaches its maximum value, presenting a state of strong mutual repulsive magnetic force.

[0060] The second capability: the two iron blocking devices 4 completely close and enter between the first magnet 1 and the second magnet 2, completely blocking the magnetic pole action surface and achieving 100% complete closure. The iron blocking devices 4 transform the repulsive force of the two magnets into the attractive force of the two magnets on the iron. The original mutual repulsion is transformed into strong mutual attraction, and the attractive force reaches its maximum value.

[0061] The third capability: Two iron blocking devices are inserted between the first magnet 1 and the second magnet 2, blocking 50% of the magnetic pole action surface. The blocked area and the unblocked area are evenly distributed. The unblocked area maintains the repulsive force of the same magnetic pole of the magnet, while the blocked area generates the attractive force of the magnet on the iron. The two are equal in size and opposite in direction, and the repulsive force and attractive force are balanced, so the two magnets do not interact.

[0062] The fourth capability: The two iron blocking devices 4 are opened from 50% to 60% to 70% to 80% to 90% to 100%. The iron blocking devices 4 gradually withdraw from the first magnet 1 and the second magnet 2 from the half-blocking state. The blocking area continuously decreases from 50% to 0%. As the blocking area decreases, the attraction of the magnet to the iron gradually weakens, and the repulsive force of the same magnetic poles gradually becomes dominant, eventually reaching the maximum repulsive force. The overall result is a continuous change in which the mutual repulsive force gradually increases.

[0063] The fifth capability: The two iron blocking devices 4 are closed from 50% to 60% to 70% to 80% to 90% to 100%. The iron blocking devices 4 are gradually inserted between the first magnet 1 and the second magnet 2 from a half-blocked state. The blocking area continuously increases from 50% to 100%. As the blocking area increases, the attraction of the magnet to the iron gradually increases, and the repulsion of the like magnetic poles is gradually canceled out, eventually reaching the maximum attraction. The whole shows a continuous change in the mutual attraction gradually increasing.

[0064] The sixth ability: The two iron blocking devices 4 open from 1% to 10% to 20% to 30% to 40% to 50%. The blocking devices gradually move out from between the first magnet 1 and the second magnet 2 from near complete closure. The blocking area continuously decreases from 99% to 50%. In the initial state, the attraction is dominant. As the blocking area decreases, the attraction gradually weakens and the repulsion gradually increases. Finally, when it is 50% open, it reaches a force balance. The overall result is a continuous change in which the mutual attraction gradually decreases.

[0065] The seventh ability: The two iron blocking devices 4 are closed from 1% to 10% to 20% to 30% to 40% to 50%. The blocking devices are gradually inserted between the first magnet 1 and the second magnet 2 from almost fully open. The blocking area continuously increases from 1% to 50%. In the initial state, the repulsive force is dominant, approaching the maximum repulsive force. As the blocking area increases, the repulsive force gradually weakens and the attractive force gradually strengthens. Finally, when it is closed at 50%, the force balance is reached. The overall result is a continuous change in which the mutual repulsive force gradually decreases.

[0066] The eighth capability: The two iron blocking devices 4 completely close between the first magnet 1 and the second magnet 2, completely blocking the magnetic pole action surface and achieving 100% complete closure. When the iron blocking device 4 is thinner than the specified size, it cannot completely counteract the repulsive force between the two magnets. Some of the repulsive force will penetrate the blocking device and act on the two magnets, forming an uncounted residual repulsive force. Its magnitude is directly related to the extent of insufficient thickness. The amount of iron-based material used in the iron blocking device 4 is reduced, and the effective adsorption area or adsorption strength of the two magnets decreases, making it impossible to generate sufficient adsorption force to completely replace the repulsive force. The mutual repulsive force between the two magnets can be increased, reduced, or eliminated by gradually thinning and adjusting the thickness of the iron blocking device 4 to achieve 100% closure of the iron blocking device 4.

[0067] The thickness of the iron blocker 4 is directly proportional to the repulsive force between the first magnet 1 and the second magnet 2 in the unobstructed state.

[0068] Specifically, the thickness of the iron stopper 4 refers to the effective working thickness of the iron stopper 4 (unit: millimeters), which needs to cover the magnetic pole interaction surface of the first magnet 1 and the second magnet 2. The material is a high magnetic permeability iron-based material, which is a key structural dimension for realizing the control of magnetic force.

[0069] Repulsive force: refers to the natural magnetic repulsion force (unit: Newton) between two magnets (with the same magnetic poles facing each other) when there is no obstruction. It is determined by the magnetic strength of the magnet itself, the area of ​​the magnetic poles, etc., and is the initial power source.

[0070] When the blocker is an iron blocker 4 made of pure iron, its thickness is made of 0.013 mm, 0.13 mm, 1.3 mm, 13 mm and 39 mm respectively, depending on the repulsive force of the two magnets. When the blocker is made of low-purity iron, its thickness is thicker than the above standards.

[0071] When the repulsive force between the two magnets reaches 1 Newton, or 100 grams of pressure, the thickness of the iron stopper 4 is 0.013 millimeters.

[0072] When the repulsive force between the two magnets reaches 10 Newtons, or 1 kg of pressure, the thickness of the iron stopper 4 is 0.13 mm.

[0073] When the repulsive force between the two magnets reaches 100 Newtons, or 10 kilograms of pressure, the thickness of the iron stopper 4 is 1.3 millimeters.

[0074] When the repulsive force between the two magnets reaches 1000 Newtons, or 100 kilograms of pressure, the thickness of the iron block 4 will be 13 millimeters.

[0075] When the repulsive force between the two magnets reaches 3000 Newtons, or 300 kilograms of pressure, the thickness of the iron stopper 4 is 39 millimeters.

[0076] When the thickness of the iron stopper 4 is manufactured according to the standards specified above, the first seven functions of the variable magnetic force technology can be realized.

[0077] When the thickness of the iron blocker 4 is set to be less than the standard thickness, when the iron blocker 4 is driven to the maximum magnetic shielding state, there is still a repulsive force between the first magnet 1 and the second magnet 2. At this time, the eighth function of the variable magnetic force technology can be realized.

[0078] Specifically, the core function of the iron blocker 4 is to convert the repulsive force of the two magnets into the attractive force of the magnet on the iron. The key is to completely block the magnetic pole action surface through its own thickness, so that the ferromagnetic material can fully adsorb the two magnets and cancel out the repulsive force. The greater the repulsive force, the higher the interaction strength of the magnetic poles of the two magnets. A thicker ferromagnetic material is needed to completely cover the magnetic pole action area, form a sufficient adsorption area and adsorption force, and completely replace the repulsive force.

[0079] When the iron blocker 4 is made slightly thicker than the specified size, it has little impact on the variable magnetic force technology. However, when the iron blocker 4 is made slightly thinner than the specified size, even if the iron blocker 4 is 100% closed, the mutual repulsion between the two magnets cannot be completely eliminated. The mutual repulsion between the two magnets is clearly transmitted through the iron blocker 4. By gradually thinning the iron blocker 4 compared to the specified size, the repulsion between the two repulsive magnets can be increased, decreased, or eliminated when the iron blocker 4 is 100% closed.

[0080] For example, when the repulsive force between two magnets reaches a pressure of 100 kg, a 13 mm thick iron blocker 4, when 100% closed, can control the repulsive force, causing the two magnets to attract each other very strongly. However, if a 6.5 mm thick iron blocker 4 is made and 100% closed when the repulsive force reaches 100 kg, the repulsive force will significantly decrease to 50 kg. When the iron blocker 4 is made slightly thinner than the specified dimensions, the repulsive force of the two magnets can be clearly seen through it. Even when 100% closed, the iron blocker 4 cannot completely eliminate the repulsive force between the two magnets when its thickness is slightly thinner than the specified dimensions. In other words, by gradually adjusting the thickness of the iron blocker 4 to be slightly thinner than the specified size, the mutual repulsion force between the two magnets can be reduced to 1 kg or less, or even eliminated. This technology can be used to arbitrarily adjust the mutual repulsion force between the two magnets. This variable magnetic force technology is not limited by the use of double-door iron blocks or single-door iron blocks.

[0081] The blocker is a magnetic blocker 25 composed of a C3 iron sheet 26 and C1 auxiliary magnets 27 and C2 auxiliary magnets 28 attached to both sides of the C3 iron sheet 26. The C1 auxiliary magnets 27 and C2 auxiliary magnets 28 have the same magnetic poles as the first magnet 1 and the second magnet 2, respectively.

[0082] Specifically, the following details the eight functions of the variable magnetic force technology that can be generated by the magnetic stopper 25:

[0083] The first capability: the two magnetic stoppers 25 completely exit the working area between the first magnet 1 and the second magnet 2, without any obstruction, achieving 100% full opening. The two magnets are magnetic poles of the same name, naturally repelling each other. When there is no obstruction, the repulsive force reaches its maximum value, exhibiting a strong mutual repulsion state.

[0084] The second capability: the two magnetic blocking devices 25 completely close and enter between the first magnet 1 and the second magnet 2, completely blocking the magnetic pole action surface and achieving 100% complete closure. The C1 auxiliary magnet 27 and C2 auxiliary magnet 28 minimize the repulsive force between the first magnet 1 and the second magnet 2 through low magnetic repulsion. The mutual repulsive force between the first magnet 1 and the second magnet 2 is reduced to an extremely low level, with no attractive force generated and only a weak repulsive force remaining.

[0085] The third capability: Two magnetic blocking devices 25 are inserted between the first magnet 1 and the second magnet 2, blocking 50% of the magnetic pole action surface. The blocked area and the unblocked area are evenly distributed. The unblocked area is strongly repelled by the first magnet 1 and the second magnet 2, while the blocked area is repelled by low magnetic force. After the two are superimposed, the mutual repulsion force is significantly reduced, resulting in an unbalanced state, but there is still a weak repulsion force.

[0086] The fourth capability: The two magnetic blocking devices 25 are opened from 50% to 60% to 70% to 80% to 90% to 100%. The magnetic blocking devices 25 gradually withdraw from the first magnet 1 and the second magnet 2 from the semi-blocking state. The blocking area continuously decreases from 50% to 0%. The interaction between the C1 auxiliary magnet 27 and the C2 auxiliary magnet 28 and the first magnet 1 and the second magnet 2 gradually weakens and eventually completely separates. The influence of low magnetic repulsion gradually disappears. The natural repulsion force of the first magnet 1 and the second magnet 2 gradually increases and eventually reaches the maximum repulsion force, showing a continuous change in the mutual repulsion force gradually increasing.

[0087] The fifth capability: the two magnetic blocking devices 25 are closed from 50% to 60% to 70% to 80% to 90% to 100%. The magnetic blocking devices 25 are gradually inserted between the first magnet 1 and the second magnet 2 from a semi-blocking state. The blocking area continuously increases from 50% to 100%. The correspondence between the C1 auxiliary magnet 27 and the C2 auxiliary magnet 28 and the first magnet 1 and the second magnet 2 is gradually improved. The low magnetic repulsion effect is gradually enhanced. The influence of the low magnetic repulsion is gradually enhanced. The natural repulsion force of the first magnet 1 and the second magnet 2 is gradually canceled out.

[0088] The sixth capability: the two magnetic blocking devices 25 open from 1% to 10% to 20% to 30% to 40% to 50%, and the magnetic blocking devices 25 gradually withdraw from between the first magnet 1 and the second magnet 2 from being nearly completely closed. The blocking area continuously decreases from 99% to 50%, and the low magnetic repulsion gradually disappears from the strongest. Initially, it is an extremely low repulsion force. As the blocking area decreases, the repulsion force gradually increases, showing a continuous change throughout the process where the mutual repulsion force gradually increases.

[0089] The seventh capability: the two magnetic blocking devices 25 are closed from 1% to 10% to 20% to 30% to 40% to 50%. The magnetic blocking devices 25 are gradually inserted between the first magnet 1 and the second magnet 2 from almost fully open. The blocking area continuously increases from 1% to 50%. The low magnetic repulsion gradually increases from none to the strongest. Initially, it is the maximum repulsion force. As the blocking area increases, the repulsion force gradually decreases to an extremely low level, showing a continuous change throughout the process where the mutual repulsion force gradually decreases.

[0090] The eighth capability: When the two magnetic blocking devices 25 are fully closed and enter between the first magnet 1 and the second magnet 2, they completely block the magnetic pole action surface, achieving 100% complete closure. When the magnetic force of the C1 auxiliary magnet 27 and the C2 auxiliary magnet 28 is adjusted up and down, the mutual repulsion force of the two mutually repelling magnets will gradually decrease and gradually increase.

[0091] Furthermore, depending on the needs, either the iron stopper 4 or the magnetic stopper 25 can be selected to meet the power output requirements in different scenarios. It has strong compatibility, effectively expands the application range, has high energy efficiency, and achieves high-precision adjustment.

[0092] It should be noted that the first magnet 1 and the second magnet 2 used in the iron blocker 4 and the magnetic blocker 25 can be either conventional magnets or novel magnets, such as... Figure 2-4 It uses a traditional magnet, which has six poles: three north poles and three south poles. These traditional magnets come in various shapes, including rectangular, square, cylindrical, curved, and others. Figure 5-7 It uses a new type of magnet with 6 magnetic poles, namely 1 S pole and 5 N poles or 1 N pole and 5 S poles. The new magnet comes in rectangular, square, arc, cylindrical and many other shapes.

[0093] Furthermore, in addition to sliding the iron blocker 4 and the magnetic blocker 25 between two mutually repelling magnets to control the magnetic force, the iron blocker 4 and the magnetic blocker 25 can also be directly attached to the surfaces of the two mutually repelling magnets to control the magnetic force.

[0094] The magnetic strength of C1 auxiliary magnet 27 and C2 auxiliary magnet 28 is lower than that of the first magnet 1 and the second magnet 2.

[0095] Specifically, the secondary magnet 27 (C1) is fixed to the bottom of the iron plate 26 (C3). The secondary magnet 27 is connected to the first magnet 1 and works. The secondary magnet 27 repels the first magnet 1, thus minimizing the repulsive force of the first magnet 1 and achieving a control function. By attaching a secondary magnet 27 (C1) with very low repulsive force to the bottom of the iron plate 26 (C3), the repulsive force between the first magnet 1 and the secondary magnet 27 is minimized, achieving the purpose of control. The magnetic force of the C1 auxiliary magnet 27 attached to the bottom of the C3 iron sheet 26 is less than 1 Newton or 1 Newton, and its thickness is about 1 mm. The opposite magnetic poles of the C1 auxiliary magnet 27 and the first magnet 1 are the same N pole. When the C1 auxiliary magnet 27 and the C2 auxiliary magnet 28 with the same pole are glued together to make a pure magnetic blocker, the two magnets repel each other. The performance of this pure magnetic blocker is slightly lower than that of the magnetic iron blocker. Therefore, a C3 iron sheet 26 is added between the C1 auxiliary magnet 27 and the C2 auxiliary magnet 28 with the same pole to make a magnetic blocker 25. At this time, the C1 auxiliary magnet 27 and the C2 auxiliary magnet 28 will not repel each other, and a magnetic blocker 25 with better control of magnetic force can be manufactured.

[0096] The secondary magnet 28 (C2) is fixed to the top of the iron plate 26 (C3). The secondary magnet 28 is connected to the second magnet 2. By repelling the second magnet 2, the secondary magnet 28 minimizes the repulsive force, thus achieving a control effect. By attaching a low-repulsive secondary magnet 28 (C2) to the top of the iron plate 26, the mutual repulsion between the second magnet 2 and the secondary magnet 28 can be minimized, achieving the control purpose. The magnetic force of the secondary magnet 28 (C2) attached to the iron plate 26 is equal to or less than 1 Newton, and its thickness is approximately 1 millimeter. The opposite poles of the secondary magnet 28 and the second magnet 2 are both the same N pole.

[0097] Furthermore, the thickness of the C1 auxiliary magnet 27 and C2 auxiliary magnet 28 used in the magnetic stopper 25 is 1 mm, and the magnetic force can be made from 1 Newton to 0.1 Newton. The lower the magnetic force of the C1 auxiliary magnet 27 and C2 auxiliary magnet 28, the better the repulsive force between the first magnet 1 and the second magnet 2 can be controlled. The thickness of the C3 iron sheet 26 can be the same as the thickness of the iron stopper 4, or it can be made thinner. For example: when the mutual repulsive force between the two magnets reaches a pressure of 1 kg, the thickness of the C3 iron sheet 26 can be made 0.13 mm; when the mutual repulsive force between the two magnets reaches a pressure of 10 kg, the thickness of the C3 iron sheet 26 can be made 1.3 mm; when the mutual repulsive force between the two magnets reaches a pressure of 100 kg, the thickness of the C3 iron sheet 26 can be made 13 mm; and when the mutual repulsive force between the two magnets reaches a pressure of 300 kg, the thickness of the C3 iron sheet 26 can be made 39 mm. Slightly thinner than the above standards is also acceptable. Since both sides of the C3 iron sheet 26 have magnets attached, we can control the repulsive force between the two repelling magnets by making the C3 iron sheet 26 slightly thinner than the above standard.

[0098] By adjusting the overall magnetization intensity of the magnetic stopper 25, the adjustable range of the repulsive force between the first magnet 1 and the second magnet 2 can be changed.

[0099] Specifically, the first magnet 1 and the second magnet 2 have extremely strong magnetic forces. If the magnetic force of the auxiliary magnet is too high, it will generate strong repulsion with the main magnet, causing the magnetic stopper 25 to get stuck between the two magnets. The low magnetic force setting allows the magnetic stopper 25 to be subjected to only a weak repulsive force, so that it slides without jamming and is suitable for the need for continuous reciprocating movement. The repulsive force of the main magnet is the power source.

[0100] By changing the magnetization-related parameters of the components, the magnetization intensity of the two auxiliary magnets can be increased or decreased, thereby directly altering the basic magnetization contribution of the magnetic blocker 25.

[0101] The power conversion mechanism includes a crankshaft 17 that is rotatably disposed and a connecting rod 18 that is hinged between the crankshaft 17 and the first magnet 1.

[0102] The drive mechanism includes a drive rod 9 and a flexible shaft 5. One end of the shaft 5 is connected to the drive rod 9 for transmission, and the other end is fixedly connected to the first magnet 1.

[0103] Specifically, the drive rod 9 is mounted on the second magnet 2 via the first fixing bracket 11, and the drive rod 9 is mounted on the first fixing bracket 11 via the second fixing clip 10. The drive rod 9 is fixedly connected to the shaft 5 via the first fixing clip 8. The shaft 5 is fixed to the stopper. The hollow shaft 7 provides sliding guidance for the shaft 5. The spring 6 assists the stopper in resetting. By manipulating the drive rod 9, the shaft 5 is driven to slide within the hollow shaft 7, thereby driving the stopper to translate between the two main magnets.

[0104] Both the first magnet 1 and the second magnet 2 are encased in a magnet shell 3 made of non-magnetic material.

[0105] The technical scope of this invention is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this invention, and all such modifications and variations should fall within the protection scope of this invention.
