Abstract

The invention discloses a magnetic pole turnover type magnetic motor based on gear transmission, which comprises a central shaft and a plurality of power units arranged around the central shaft, and each unit is composed of a base, a stator magnet, a rotatable rotor magnet and a mounting frame. A gear is arranged at the tail end of the rotor magnet and can be selectively meshed with a rack fixed on the inner side of the stator magnet. And a track is arranged on the base and is matched with a sliding plate on the rotor magnet. When the gear is engaged with the rack, the rotor magnet enters the magnetic pole overturning area and is forced to rotate for half a circle, so that the magnetic pole direction is reversed; after the gear is separated from the rack, the sliding plate is jointed with the track, the rotor magnet enters a power area in a new magnetic pole direction, and power is continuously output by utilizing attraction or repulsive force with a stator magnetic field. Especially, five power units are preferably selected to work alternately at a specific phase difference, so that resultant force output by most rotors is sufficient to overcome magnetic resistance generated when few rotors turn over, and self-sustaining operation without external energy is achieved.

Description

Technical Field

[0001] This invention relates to a magnetic field power device, specifically a device that converts magnetic energy into continuous rotational power by periodically reversing the direction of magnetic poles through a mechanical transmission mechanism. Background Technology

[0002] Utilizing the magnetic field properties of magnetic materials such as ferrites and neodymium iron boron to generate power has long been a research direction in industry. Common magnetic field power devices, such as electric motors, require an external power source to continuously change the direction of the current to drive the rotor to rotate. However, achieving continuous operation of the device without relying on external electrical energy input is a significant challenge.

[0003] Existing technologies include numerous schemes that attempt to utilize the inherent attractive and repulsive forces between magnetic materials to create power devices. However, these schemes generally suffer from a core flaw: when the rotor magnetic assembly moves to a position balanced with the stator magnetic field—the "dead point"—the movement stops. To continue movement, the direction of the magnetic field must be changed; otherwise, the rotor will be pulled or pushed back, preventing unidirectional continuous movement. Some schemes attempt to alter the magnetic field through complex electromagnetic control or mechanical interruption, but this not only introduces external energy dependence but also increases structural complexity and reduces reliability. Summary of the Invention

[0004] The present invention aims to solve the above-mentioned technical problems by providing a magnetic pole reversing magnetic motor based on gear transmission. Its core is to use a built-in mechanical transmission structure to forcibly reverse the magnetic pole direction of the rotor assembly at a specific time, thereby cleverly using magnetic force to cross the dead point and form a stable unidirectional rotational power output.

[0005] To solve the above-mentioned technical problems, the technical solution provided by the present invention is: a magnetic pole reversing magnetic motor based on gear transmission, comprising a central shaft and at least one set of magnetic power units, characterized in that: the magnetic power unit comprises a base, a stator magnet, a rotor magnet and a mounting frame; the mounting frame is fixedly connected to the central shaft; The rotor magnet is rotatably mounted on the mounting frame; a gear is provided at the end of the rotor magnet, and a rack is fixedly provided on the inner side of the stator magnet; the gear can selectively mesh with or disengage from the rack. The base is provided with a track, and a sliding plate is fixedly provided on the rotor magnet. When the gear and rack are separated, the sliding plate engages with the track and can slide along it.

[0006] Furthermore, the magnetic power units are arranged in five groups along the central axis; the five stator magnets are tile-shaped magnets and arranged in an array along the axial direction; the five rotor magnets are evenly distributed around the central axis.

[0007] Furthermore, the gear-driven magnetic pole reversing magnetic motor includes a magnetic pole reversing region and a power region B; When the gear of any rotor magnet meshes with the rack of the corresponding stator magnet, the rotor magnet is in the magnetic pole reversal zone A. The rotor magnet is forced to rotate around its own axis through the transmission of the gear and rack, so as to realize the reversal of its magnetic pole direction. When the gear separates from the rack and the slide plate slides on the track, the rotor magnet is in the power zone B, its magnetic pole direction is maintained, and it continuously interacts with the magnetic field of the stator magnet to output power.

[0008] Furthermore, the five rotor magnets are configured to alternately enter the pole reversal zone A and the power zone B; During operation, at least three rotor magnets are in power zone B outputting power, and at most one rotor magnet is in magnetic pole reversal zone A performing magnetic pole reversal, while the remaining rotor magnets are in power zone B and transitioning to magnetic pole reversal zone A; the power output by the rotor magnets in power zone B is configured to overcome the magnetic pole reversal resistance experienced by the rotor magnets in magnetic pole reversal zone A.

[0009] Furthermore, the gear serves as a force-saving lever, and its leverage ratio is configured such that the force required to drive the gear to rotate is less than the magnetic resistance directly experienced when the rotor magnet's poles reverse.

[0010] Furthermore, the gear teeth include at least two raised teeth, the height of which is greater than that of the other teeth. The raised teeth are positioned to make contact first when the gear is about to engage or disengage from the rack, so as to ensure the smoothness of the engagement process.

[0011] Furthermore, the stator magnet is a radially magnetized tile-shaped permanent magnet; the rotor magnet is a bar-shaped permanent magnet with its magnetic poles perpendicular to its length direction; the central shaft, base, mounting frame, track, and slide plate are all made of non-magnetic materials.

[0012] Furthermore, the magnetic pole reversal process of the rotor magnet is as follows: when the gear is driven to rotate by the rack, it drives the rotor magnet to rotate about 0 degrees around its own axis, causing its magnetic pole direction to reverse from pointing to the N (S) pole of the stator magnet to pointing to the S (N) pole, thereby changing from a repulsive (attractive) state to an attractive (repulsive) state under the action of the magnetic field, thus realizing the continuity of power output.

[0013] The advantages of this invention compared to the prior art are: 1. Through ingenious mechanical layout and magnetic pole reversal design, the power output of the majority of rotors is used to overcome the reversal resistance of the minority rotors, thus achieving self-sustaining operation without the need for external energy input.

[0014] 2. The mature and reliable transmission method of gears is used to achieve magnetic pole reversal, and the slide-track system is combined to keep the rotor stable in the non-reversal zone, resulting in a robust structure and long service life.

[0015] 3. The gear mechanism acts as a force-saving lever, significantly reducing the operating force required for magnetic pole reversal, making it possible to drive the device using the difference between magnetic attraction and repulsion. The increased tooth height further enhances the smoothness and reliability of the transmission.

[0016] 4. The alternating operation design of the five rotors ensures the continuity and smoothness of power output, effectively avoiding the "dead point" problem that is difficult to overcome by a single rotor device. Attached Figure Description

[0022] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0023] This embodiment provides a magnetic pole reversing motor based on gear transmission. Through a set of purely mechanical transmission mechanisms, when the rotor magnetic assembly revolves to a specific position, it is forced to rotate 180 degrees around its own axis, thereby achieving precise and timed reversal of the magnetic pole direction. This reversal action allows the magnetic field force between the rotor magnetic assembly and the stator magnetic assembly to change from impeding rotation to driving rotation, thus utilizing magnetic field energy to generate continuous, unidirectional rotational power.

[0024] The magnetic motor includes a central shaft 1 that serves as the center of rotational output. The central shaft 1 is made of a non-magnetic material and is supported at both ends on an external frame by bearings (gears not shown in the figure), allowing it to rotate freely.

[0025] Five mounting brackets 5 are installed parallel to and fixed along the axial direction of the central shaft 1. The mounting brackets 5 and the central shaft 1 are connected by a key or interference fit to ensure no relative rotation. Each mounting bracket 5 has a rotor magnetic assembly 4 rotatably mounted via rolling or sliding bearings. The rotor magnetic assembly 4 is a strip-shaped structure made of high-performance magnetic material such as neodymium iron boron, with its N and S poles distributed on its two end faces along its length, i.e., the magnetic pole direction is perpendicular to the length direction of the rotor magnetic assembly 4. This design is a prerequisite for achieving the flipping of the magnetic poles by rotating around the shaft.

[0026] At the end of each rotor magnetic assembly 4, i.e., the end furthest from the central shaft 1, a gear 6 is fixedly installed. This gear 6 is the core component for realizing magnetic pole reversal and exerting a force-saving lever effect. Two raised teeth 6.1 are provided in the gear teeth. The tooth height of these two raised teeth 6.1 is slightly larger than that of other standard gear teeth, and their circumferential position has been precisely calculated. Their function is to ensure that the raised teeth 6.1 make the first guiding contact at the moment when the gear 6 is about to engage with the rack 7 and when it is about to completely disengage, thereby achieving smooth and shock-free engagement and disengagement, avoiding the "tooth-hitting" phenomenon, and ensuring the reliability of the transmission.

[0027] The power unit also includes five fixed bases 2, each corresponding to a power unit. The base 2 is a ring-shaped structure, fixed to the non-magnetic frame, and made of non-magnetic material. On the inner edge of each base 2, a stator magnetic assembly 3 is fixed. This stator magnetic assembly 3 is a tile-shaped, semi-circular ring structure, also made of high-performance magnetic material and radially magnetized; that is, its inner arc surface is one magnetic pole, such as the S pole, and its outer arc surface is another magnetic pole, such as the N pole. The five stator magnetic assemblies 3 are arranged in an axial array along the central axis 1, and the magnetic field direction remains consistent.

[0028] An arc-shaped rack 7 is fixedly installed on the inner arc surface of the stator magnetic assembly 3. The installation position and arc length of the rack 7 are precisely designed so that it can mesh with the gear 6 at the end of the rotor magnetic assembly 4 only within a specific circumferential angle range. This specific area is the magnetic pole reversal zone A.

[0029] On the base 2, an arc-shaped track 8 concentric with the rack 7 is also provided. The surface of the track 8 can be hardened or coated with a low-friction material. Correspondingly, a sliding plate 9 is fixedly connected to the middle of the rotor magnetic assembly 4. The sliding plate 9 can be made of a self-lubricating material. When the gear 6 is disengaged from the rack 7, the lower surface of the sliding plate 9 falls precisely on the track 8 and can slide along the track 8. This area is the power zone B. The cooperation between the sliding plate 9 and the track 8 plays a key role in stabilizing the attitude of the rotor magnetic assembly 4 and maintaining its magnetic pole direction during the non-flipping phase.

[0030] 2. Working principle and process The reason why this device can operate continuously is that it precisely combines the coordinated work of the five rotor magnetic components 4 with the regional division of magnetic pole reversal zone A and power zone B.

[0031] Initial state settings: as attached Figure 5 As shown, five rotor magnetic assemblies 4-1, 4-2, 4-3, 4-4, and 4-5 are evenly distributed around the central axis 1. Assume that at a certain moment, the gear 6 of rotor magnetic assembly 4-1 begins to mesh with the rack 7, entering the pole reversal zone. Simultaneously, the gear 6 of rotor magnetic assembly 4-4 just disengages from the rack 7, and its sliding plate 9 falls into track 8, entering the power zone B. The remaining rotor magnetic assemblies 4-2, 4-3, and 4-5 are also in the power zone B, with their gears 6 suspended and their sliding plates 9 sliding on track 8.

[0032] Step 1: Magnetic pole reversal As the first rotor magnetic assembly 4-1 revolves around the central shaft 1, its gear 6 is forced to rotate due to its meshing with the fixed rack 7. The gear 6 rolls approximately half a revolution on the rack 7, corresponding to a 180-degree rotation, which drives the rotor magnetic assembly 4-1 to precisely rotate 180 degrees around its own axis via the mounting shaft.

[0033] This rotational motion completes the forced reversal of the magnetic pole direction. For example, before the reversal, the N pole of the rotor magnetic assembly 4-1 points towards the N pole of the stator magnetic assembly 3, exhibiting a repulsive force; after the reversal, its S pole points towards the N pole of the stator magnetic assembly 3, changing to an attractive force. The meshing of the gear and rack is essentially a rotating lever system. The pitch circle radius of the gear is the resistance arm, while the magnetic resistance actually acts on the center of the magnet, forming a shorter lever arm. According to the lever principle (effort × effort arm = resistance × resistance arm), when the effort arm (gear radius) is much larger than the resistance arm (distance from the center of the magnet to the shaft), a smaller tangential force can be used to drive the gear to overcome the enormous magnetic resistance acting on the magnet. This makes it possible to achieve magnetic pole reversal with limited power input.

[0034] Step Two: Power Output After the first rotor magnetic assembly 4-1 completes the magnetic pole reversal, along with the other rotor magnetic assemblies already in the power zone B, their gears 6 and racks 7 separate, and the slide plate 9 slides on the track 8. At this time, the magnetic pole direction of rotor magnetic assembly 4 is constrained and kept fixed by the slide plate-track system.

[0035] In this state, the magnetic poles of the rotor magnetic assembly 4 continuously interact with the magnetic field of the stator magnetic assembly 3. The rotor in the attractive state is strongly attracted, while the rotor in the repulsive state is continuously repelled. This magnetic force is converted into a tangential force that propels the rotor magnetic assembly 4 to revolve around the central axis 1, thereby generating torque that drives the central axis 1 to rotate and outputs power externally.

[0036] Step 3: Collaborative Work and Overcoming Dead Ends The five rotor magnetic components 4 alternate phases in the circumferential direction. At any given time, they maintain a "four working, one flipping" configuration. That is, typically four rotor magnetic components are in the power zone B, outputting power, while only one rotor magnetic component is in the pole flipping zone A, consuming energy to flip the magnetic pole.

[0037] The total power output from the four rotors in power zone B, after being integrated through the central shaft 1, is far greater than the reversing resistance that a single rotor needs to overcome in pole reversing zone A. This creates a "many helping one" situation, using the power generated by the majority of rotors to easily "pull" or "push" the rotor that is currently in a dead position and reversing smoothly overcoming the difficulty, thus achieving self-sustaining continuous operation without external energy. The raised teeth 6.1 on the gears ensure the smoothness of meshing transitions during alternation, maintaining operational stability.

[0038] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
