[0022] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and the illustrations of the present invention (the engine described in the illustrations of the present invention is a V-type 6-cylinder engine), and are not used to limit the present invention.

[0023] See also Figure 1-3 The present invention provides a technical solution: a structure of a permanent magnet DC engine, including a permanent magnet component, a mechanical component, an electromagnetic component, an electronic control component, and a battery component. The permanent magnet component includes a rotor shaft 12, a rotor shaft 13, a rotor shaft permanent magnet 14, and a permanent magnet piston permanent magnet 21. The rotor shaft permanent magnet 14 is arranged around the outer surface of the rotor shafts 12 and 13, adapted to the permanent magnet piston permanent magnet 21, and located inside the permanent magnet piston permanent magnet 21. The mechanical component 2 includes a cylinder body 1, a permanent magnet piston 5, a slide rail seat 18, a slide rail 19, a connecting rod 6, a crankshaft 7, gears 8, 9, 10, 11, a motor 2, and a flywheel 16. The connecting rod 6 is rotatably connected to the permanent magnet piston 5, and the connecting rod 6 is located below the permanent magnet piston 5. The crankshaft 7 is rotatably connected to the connecting rod 6, and the connecting rod 6 is located outside the crankshaft 7. One end of the crankshaft 7 is set as an output end, and the other end is connected to the rotor shaft gears 10 and 11 through the crankshaft transmission gear 8 and the intermediate transfer gear 9 to rotate the rotor shaft 12 and 13. The electromagnetic assembly includes an electromagnetic coil and an electromagnetic coil cap. The electromagnetic coil is wound around the outer surface of the electromagnetic coil cap. The electromagnetic coil cap is installed above the cylinder body and corresponds to the permanent magnet piston 5. The electronic control assembly includes a crankshaft position sensor 3 and a corresponding electronic control assembly, which is used for circuit supply and stop of the electromagnetic coil and current size control. The battery assembly is composed of multiple groups of batteries connected in series and parallel to provide power storage and power supply for the engine.

[0024] In this embodiment, the permanent magnet piston permanent magnet 21 is composed of two sub-components, and the N poles of the two sub-components are both facing inward. The rotation of the rotor shafts 12 and 13 drives the rotor shaft permanent magnets 14 on the outer surface to rotate inside the permanent magnet piston permanent magnet 21. When the rotor shaft rotates until the N pole magnetic flux lines of the rotor shaft permanent magnet 14 and the N pole magnetic flux lines of the lower part of the permanent magnet piston 21 are 90°, the repulsive force reaches the maximum when they start to be parallel. Then, when it continues to rotate 90°, the distance between the rotor shaft permanent magnet and the permanent magnet of the permanent magnet piston reaches the maximum. In this process, the permanent magnet piston 5 is forced to move linearly in the direction of the repulsive force, that is, it moves downward. When the rotor shaft continues to rotate, it will begin to interact with the upper part of the permanent magnet of the permanent magnet piston. Similarly, the permanent magnet piston 5 is forced to move linearly in the direction of the repulsive force, that is, it moves upward. Therefore, during the process of the rotor shafts 12 and 13 rotating one circle, the permanent magnet piston 5 reciprocates. Each cylinder of the permanent magnet DC motor has the same structure. Under the interaction between the rotor shaft permanent magnets installed at different rotation angles of the rotor shaft and the permanent magnets of the permanent magnet pistons in each cylinder body, they cooperate to operate and rotate the crankshaft together.

[0025] In this embodiment, when in use, first the motor is started to rotate the flywheel, the flywheel rotates the crankshaft, the crankshaft position sensor transmits a signal to energize the corresponding electromagnetic coil to perform work synchronously with the movement of the rotor shaft permanent magnet, and the rotor shaft permanent magnet performs work as follows: the crankshaft drives the crankshaft transmission gear 8, which rotates the rotor shaft 12 and 13 through the transmission of the intermediate transfer gear 9 and the rotor shaft gears 10 and 11. The rotation of the rotor shaft 12 and 13 drives the rotor shaft permanent magnet 14 to rotate. When the N pole of the rotor shaft permanent magnet 14 is opened to the N pole of any one of the upper and lower sub-components of the permanent magnet piston 21, the permanent magnet 21 is rotated. When the two connecting rods meet, the permanent magnet piston 5 will be pushed to move up and down, so that the permanent magnet piston will reciprocate. When the permanent magnet piston 5 moves up and down, it will drive the connecting rod 6 to move up and down. The downward movement of a single connecting rod 6 drives the turntable of the crankshaft 7 to rotate a certain angle. The asynchronous reciprocating up and down movement of multiple connecting rods drives the crankshaft 7 to move axially, so that one end of the crankshaft 7 drives the rotor shafts 12 and 13 to rotate through the transmission of the crankshaft transmission gear 8, the intermediate transfer gear 9 and the rotor shaft gears 10 and 11, thereby achieving the purpose of mutual conversion between permanent magnet magnetic energy and mechanical kinetic energy. The other end of the crankshaft 7 is set as the output end to achieve the purpose of power output.

[0026] Furthermore, the rotor shaft permanent magnet 14 and the permanent magnet piston permanent magnet 21 form a magnetic group, and the entire V-shaped cylinder structure is composed of six magnetic groups.

[0027] In this embodiment, six groups of magnetic groups are arranged in the entire structure to provide axial rotational force to the crankshaft 7, thereby providing sufficient power for the operation of the entire structure and maximizing the function of the entire structure. On the other hand, this is to avoid the two groups from canceling each other out and causing the entire structure to fail.

[0028] Furthermore, the rotor shaft permanent magnets 14 are configured to be semicircular or fan-shaped, installed on the rotor shaft assembly, and evenly distributed along the outer surfaces of the rotor shafts 12 and 13. That is, if there are six rotor shaft permanent magnets 14, the rotation angles between the six magnets are 60° in a certain direction.

[0029] In this embodiment, a semicircular or fan-shaped rotor shaft permanent magnet 14 is provided to facilitate axial rotation inside the permanent magnet piston permanent magnet 21. The rotor shaft permanent magnet 14 is evenly distributed and installed on the outer surface of the rotor shafts 12 and 13 in all directions along a certain rotation direction. The asynchronous movement of multiple permanent magnet piston permanent magnets 21 can be achieved, thereby driving the crankshaft 7 to achieve rotation of the crankshaft 7. When six groups of magnetic groups are provided in the entire structure, the angular rotation interval of each rotor shaft permanent magnet on the outer surface of the rotor shaft is 60°, so when there are multiple groups of magnetic groups in the entire structure, the angle of each rotor shaft permanent magnet on the outer surface of the rotor shaft is an equal portion of 360°.

[0030] Furthermore, the permanent magnet 21 of the permanent magnet piston can be processed into a cylindrical or square shape, and is composed of two identical sub-components connected together, with the N poles of the two sub-components facing inwards.

[0031] In this embodiment, the permanent magnet piston permanent magnet 21 is processed from a cylindrical or square shape, which, on the one hand, facilitates the installation of the permanent magnet piston permanent magnet 21, and on the other hand, cooperates with the installation of the rotor shaft permanent magnet 14 inside it. The permanent magnet piston permanent magnet 21 is composed of two identical sub-components connected together, and the N poles of the two sub-components are both facing inward, providing conditions for the up and down reciprocating motion of the permanent magnet piston 5.

[0032] Furthermore, the rotor shafts 12 and 13 rotate axially, and the rotor shaft permanent magnets 14 also move axially; the permanent magnet pistons 5 move back and forth linearly, and the plurality of permanent magnet piston permanent magnets 21 move along the same linear direction.

[0033] In this embodiment, the rotor shaft permanent magnet 14 is driven to rotate by the rotation of the rotor shafts 12 and 13. When the N pole of the rotor shaft permanent magnet 14 meets any N pole of the upper and lower components of the permanent magnet piston permanent magnet 21, it will push the permanent magnet piston permanent magnet 21 to move up and down, so that the permanent magnet piston 5 reciprocates.

[0034] Furthermore, the fan-shaped side of the rotor shaft permanent magnet 14 is an N pole, and the interior of the two permanent magnet piston permanent magnets 21 is a concave curved shape when the sub-components are combined. Each cylinder of the permanent magnet DC motor has the same structure, and the rotor shaft permanent magnets installed at different rotation angles of the rotor shaft interact with the permanent magnet piston permanent magnets in each cylinder body, and operate in coordination to rotate the crankshaft together.

[0035] In this embodiment, the interior of the two permanent magnet piston permanent magnets 21 is concave when the sub-components are combined, leaving space for the rotor shaft permanent magnet 7 to push the permanent magnet piston permanent magnet 21 to move up and down and space for its own rotation. Because of the magnetic properties of the rotor shaft permanent magnet 7 and the permanent magnet piston permanent magnet, and according to the principle that opposites attract and likes repel, when the entire rotor shaft permanent magnet 7 rotates inside the groove, the repulsive force and attractive force in the same direction change to each other.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
