Description

Technical Field

[0001] This invention relates to the field of magnetic power, and in particular to a mechanism for outputting energy generated by magnetic interactions. Background Technology

[0002] Magnetism produces energy changes through interaction. During magnetic interaction, if there is no collision between magnets, the energy change primarily involves mutual attraction increasing energy, while mutual repulsion also increases energy. The process of magnetic interaction is complex, mainly manifested in the presence of strong magnetic reluctance points about 5-8 mm inside the magnetic poles (this varies depending on the strength of the magnet). Figure 23 Points A and B are shown. Points A and B are the equilibrium points of magnetic pole interaction when the moving magnet enters the inner side of the stationary magnet. If the direction of the magnetic poles of the moving magnet is not changed and adjusted in time, then regions C and D will be regions where the magnetic force does negative work. During the entire process of magnetic interaction, energy is lost and there is no output in the end.

[0003] Therefore, the purpose of this invention is to address how to adjust the magnetic pole direction of the moving magnet in a timely manner so that the magnetic interaction can fully exert its energy. Summary of the Invention

[0047] Refer to Figure 2 and Figure 9 As shown, the moving component 2 includes a moving frame 21; the magnetic pole alignment component 3 is mounted inside the moving frame 21 via a shaft 34; the magnetic pole alignment component 3 has a rotational degree of freedom relative to the moving frame 21; at least one of the two sides of the moving frame 21 is fixed with a moving rod 22; the moving rod 22 passes through the housing 1. The housing 1 is provided with a bearing 17 where the moving rod 22 passes; the moving rod 22 can control the direction of movement of the moving magnet and also transmit the kinetic energy of the moving magnet outward.

[0050] Refer to Figure 5 and Figure 6 As shown, the first track plate 151 is fixed in the first housing 11, and the second track plate 152 is fixed in the second housing 12; the first intermediate track plate 153 and the second intermediate track plate 154 are fixed in the first housing 11 or the second housing 12.

[0051] To facilitate the explanation of the principle of the mechanism for outputting energy generated by magnetic interaction in this embodiment, the direction is defined as follows: Figure 10 In the main view direction, the moving frame moves left and right; the first housing 11 is the lower side of the housing, and the second housing 12 is the upper side of the housing. The fixed magnet is fixed in the middle area of ​​the top side inside the housing (or it can be fixed in the middle area of ​​the bottom side inside the housing); the left end of the fixed magnet is the N pole, and the right end is the S pole (of course, the left end can also be the S pole, and the right end is the N pole). The directional rack is located at the top of the front side inside the housing, and the track assembly is located on the rear side inside the housing; the first intermediate track plate is located in the left area, and the second intermediate track plate is located in the right area. The following description follows this directional setting. Of course, this setting is only one case in this embodiment and does not constitute a limitation on the protection scope of this application.

[0052] The working process of a mechanism for outputting energy generated by magnetic interaction in this embodiment includes the following six strokes:

[0053] The first stroke, at the beginning of the first stroke (e.g.) Figure 12 As shown), the moving magnet is located on the left side of the track assembly, and the lever assembly is not in the first or fourth track; the S pole of the moving magnet faces the N pole of the stationary magnet (opposite poles attract); during the first stroke, the moving magnet moves to the right and approaches the stationary magnet using the force of like poles attracting; at this time, due to the presence of the first intermediate track plate, the lever assembly enters the first track between the first intermediate track plate and the first track plate. The first track cooperates with the lever assembly, preventing the moving magnet from rotating. This design also ensures that the subsequent directional gear meshes with the directional rack in the designated position; until the end of the first stroke (e.g. Figure 13As shown (also known as the second stage), the lever assembly is located at the end of the first track and is in a state of disengagement, while the directional gear and directional rack are in a state of engagement; the S pole of the moving magnet is directly below the N pole of the stationary magnet.

[0054] The second leg of the journey, such as Figure 13 , Figure 14 and Figure 15 As shown, during the continued rightward movement of the moving magnet, the directional gear rotates counterclockwise in conjunction with the meshing of the directional rack. At this time, the middle area between the first and second track plates provides space for the lever assembly, allowing the magnetic pole directional assembly to rotate with the directional gear, thus driving the moving magnet to rotate and adjust the magnetic pole direction until the end of the second stroke (e.g., ...). Figure 15 As shown), the lever assembly is located at the entrance of the second track and is in the ready-to-enter state, while the directional gear and directional rack are in the ready-to-disengage state; the S pole of the moving magnet is directly below the S pole of the stationary magnet.

[0055] The third itinerary, such as Figure 15 As shown, the lever assembly enters the second track between the second intermediate track plate and the second track plate. Under the influence of the S pole of the fixed magnet (like poles repel each other), the S pole of the moving magnet continues to move to the right. At this time, although the moving magnet has a tendency to rotate (the N pole of the moving magnet tends to turn towards the S pole of the fixed magnet), the lever assembly is stopped by the second track, preventing the magnetic pole reversal assembly from rotating until the end of the third stroke (e.g., Figure 16 As shown), the lever assembly disengages from the second track and has the freedom to rotate counterclockwise;

[0056] In the fourth stroke, the S pole of the moving magnet continues to move to the right under the influence of the S pole of the stationary magnet (like poles repel each other). Simultaneously, because the lever assembly is not restricted by the second intermediate track plate, the moving magnet rotates under the repulsive force of like poles until the end of the fourth stroke (e.g., Figure 17 As shown), the lever assembly is located at the entrance of the third track and is in the ready-to-enter state, with the N pole of the moving magnet facing the S pole of the stationary magnet;

[0057] In the fifth stroke, the S pole of the moving magnet moves to the left under the influence of the N pole of the stationary magnet (opposite poles attract), and simultaneously, the lever assembly enters the third track, as shown. Figure 18 As shown; until the end of the fifth stroke, the lever assembly is located at the end of the third track and is in a state of disengagement, while the directional gear and directional rack are in a state of engagement; the N pole of the moving magnet is directly below the S pole of the stationary magnet;

[0058] In the sixth stroke, as the moving magnet continues to move to the left, the directional gear, engaged with the directional rack, rotates clockwise, as... Figure 19As shown; the middle area between the first and second track plates provides space for the lever assembly, allowing the magnetic pole adjustment assembly to rotate with the adjustment gear, thereby driving the rotating magnet to adjust the magnetic pole direction until the end of the sixth stroke (e.g. Figure 20 As shown), the lever assembly is located at the entrance of the fourth track and is in a ready-to-enter state. The first intermediate track plate restricts the lever assembly, thereby restricting the clockwise rotation of the magnetic pole adjusting assembly, while the adjusting gear and adjusting rack are in a ready-to-disengage state; the N pole of the moving magnet is directly below the N pole of the fixed magnet.

[0059] The seventh leg of the journey, such as Figure 21 As shown, the lever assembly enters the fourth track between the first intermediate track plate and the second track plate. Under the action of the fixed magnet (like poles repel each other), the moving magnet continues to move to the left until the end of the seventh stroke. At this point, the lever assembly disengages from the fourth track and has the freedom to rotate counterclockwise.

[0060] Eighth journey, such as Figure 22 As shown, the N pole of the moving magnet, under the influence of the N pole of the stationary magnet (like poles repel each other), rotates clockwise because the lever assembly is not restricted by the first intermediate track plate, until the end of the eighth stroke (as shown). Figure 12 As shown), the S pole of the moving magnet faces the N pole of the stationary magnet;

[0061] Then, repeat the first to eighth steps as described above.

[0062] The above embodiments should not limit the present invention in any way. All technical solutions obtained by equivalent substitution or equivalent conversion fall within the protection scope of the present invention.
