[0023] The embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings.

[0025] The accompanying drawings are marked as follows: outer magnet N, inner magnet S, magnet frame 1, guide slide groove 1a, coil slide 2, coil 21, A terminal 211, B terminal 212, positioning balance wheel assembly 3, positioning swing wheel 31, swing wheel shaft 32, air-conditioning compressor 4, piston rod 41, crankshaft 5, connecting rod 6, flywheel 7, helical tooth shape 71, shutdown magneto-electric power retaining safety switch 8, helical tooth 81, carbon brush assembly 9, crankshaft positive part 91, crankshaft negative part 92, insulating block 93, A carbon brush 94, B carbon brush 95, positive pole swivel 96, negative pole swivel 97, positive pole brush 98, negative pole brush 99.

[0026] In the prior art, the patent application with publication number CN201710102772 discloses a DC reciprocating thruster. When the device is used on an air-conditioning compressor, the power required by the air-conditioning compressor varies at different times, and the power converted by the device is basically a stable power, so the generated force is wasted. The present invention discloses a magnetoelectric power machine, which can reduce the waste of force by storing and releasing power. Figure 1 and Figure 2As shown, the magneto-electric power machine of the present invention comprises an outer magnet N and an inner magnet S with opposite magnetic poles arranged opposite to each other, and a coil slide 2 wound with a coil 21. The outer magnet N is fixedly mounted on the outer side of the magnet frame 1, and the inner magnet S is fixedly mounted on the inner side of the magnet frame 1. The coil slide 2 is slidably mounted on the magnet frame 1, and the coil 21 wound on the coil slide 2 is located between the outer magnet N and the inner magnet S. In this way, the coil 21 is in the magnetic field. When the coil 21 is energized, it can cut the magnetic lines of force to generate an Ampere force acting on the coil slide 2, so that the coil slide 2 can slide upward or downward along the magnet frame 1 as the energization direction changes. An air-conditioning compressor 4 is installed above the magnet frame 1, and the piston rod 41 of the air-conditioning compressor 4 is hinged with the upper end of the coil slide 2, so that when the coil slide 2 moves, it can drive the piston rod 41 of the air-conditioning compressor 4 to move synchronously, so that the air-conditioning compressor 4 can inhale and exhaust air to do work. The greatest contribution of the present invention is that a crankshaft 5 is rotatably installed under the magnet frame 1 through a bearing, a connecting rod 6 for power transmission is connected between the crankshaft 5 and the coil slide 2, and a flywheel 7 is installed at one end of the crankshaft 5. In this way, when the air-conditioning compressor 4 is at a low force, the excess power converted by the coil slide 2 can be transmitted to the flywheel 7 through the connecting rod and the crankshaft, and the power is stored by the rotation of the flywheel 7. When the air-conditioning compressor 4 is at the maximum force, causing the coil slide 2 to slow down due to large resistance, the flywheel can reverse the coil slide 2 through the inertia of rotation to accelerate the movement and do work on the air-conditioning compressor 4. Since the present invention is equipped with a crankshaft, a connecting rod and a flywheel, a change in force is also generated during the force storage process, which affects the travel trajectory of the coil slide 2, thereby reducing the waste of force.

[0027] The present invention installs a carbon brush assembly 9 electrically connected to the coil 21 at the other end of the crankshaft 5. The carbon brush assembly 9 is used to provide a current input circuit for the coil 21. The carbon brush assembly 9 is installed on the crankshaft 5, and the automatic switching of the input current to the coil 21 is realized by the rotation of the crankshaft 5. The outer side of the flywheel 7 is installed with a shutdown magneto-electric power position-holding safety switch 8 that is matched with the flywheel and is used to limit the position of the coil slide 2 after shutdown. The shutdown magneto-electric power position-holding safety switch 8 can ensure that the position of the coil slide 2 of the magneto-electric power machine after shutdown can ensure normal startup next time.

[0028] In the embodiment, in order to ensure the stability of the coil slide 2 moving up and down, the present invention also processes a guide groove 1a on the magnet frame 1, and the coil slide 2 is slidably arranged in the guide groove 1a of the magnet frame 1, and the guide groove 1a can provide a guiding effect for the coil slide 2 to slide up and down.

[0029] Since the force exerted by the connecting rod 6 on the coil slide 2 is not a vertical force, in order to ensure that the coil slide 2 does not deviate in the guide slot 1a of the magnet frame 1 and can move up and down flexibly, the present invention also symmetrically installs a positioning balance wheel assembly 3 on the left and right sides of the magnet frame 1 to prevent the coil slide 2 from deviating. Figure 1 It can be seen that two pairs of four positioning balance wheel assemblies 3 are installed on the magnet frame 1 of the present invention. The positioning balance wheel assembly 3 is composed of a positioning swing wheel 31 and a swing wheel shaft 32. The swing wheel shaft 32 is fixed on the magnet frame 1. The positioning swing wheel 31 is rotatably installed on the swing wheel shaft 32, and the positioning swing wheel 31 is in rolling contact with the outer side surface of the coil slide 2.

[0030] The upper end of the connecting rod 6 of the present invention is hinged below the coil slide 2 via a connecting rod pin, and the lower end of the connecting rod 6 is hinged to the crank rotation of the crankshaft 5.

[0031] In the embodiment Figure 3 As shown, the carbon brush assembly 9 of the present invention is composed of a crankshaft electrode part that rotates synchronously with the crankshaft 5 and a carbon brush part that is frictionally contacted and electrically connected to the crankshaft electrode part; the electrode part includes a crankshaft positive electrode part 91 and a crankshaft negative electrode part 92 that are symmetrically arranged, and an insulating block 93 that is arranged between the crankshaft positive electrode part 91 and the crankshaft negative electrode part 92. The carbon brush part includes an A carbon brush 94 and a B carbon brush 95 that are arranged 180 degrees apart in the circumferential direction. The coil 21 has two terminals. For the convenience of description, we name one of the two terminals as the A terminal 211 and the other terminal as the B terminal 212. The A carbon brush 94 is electrically connected to the A terminal 211 of the coil 21, and the B carbon brush 95 is electrically connected to the B terminal 212 of the coil 21.

[0032] In the embodiment, Figure 5 As shown, four helical teeth 71 are processed with equal arcs on the outer ring of the flywheel 7, and four helical teeth 81 for engaging with the helical teeth 71 on the flywheel 7 are processed on the shutdown magneto-electric power position-holding safety switch 8. When the machine is shut down, the shutdown magneto-electric power position-holding safety switch 8 is turned on, and the shutdown magneto-electric power position-holding safety switch 8 can push the helical teeth 81 to move forward to engage with the helical teeth 71 on the flywheel 7, thereby limiting the position of the coil slide 2 through the crankshaft 5 and the connecting rod 6. The position of the coil slide 2 after the machine is shut down is one-fourth of the total stroke of the coil slide 2, or three-fourths of the total stroke of the coil slide 2, thereby ensuring that the magneto-electric power machine can work normally after power is turned on.

[0033] If the magneto-electric power machine is a single machine or a dual machine symmetrical linkage, it has a defect, that is, after shutdown, if the coil slide 2 stops at the upper vertex or the lower vertex position, the A carbon brush 94 and the B carbon brush 95 happen to engage with the insulating block 93. At this time, after power is turned on, the coil 21 cannot connect to the current, which is a dead state. Therefore, in order to overcome this defect, the present invention provides a shutdown magneto-electric power retention safety switch 8 to ensure that when the machine is shut down, the A carbon brush 94 and the B carbon brush 95 will not engage with the insulating block 93.

[0034] In the embodiment, Figure 4 and Figure 5 As shown, the crankshaft 5 of the present invention is fixedly provided with a positive rotating ring 96 connected to the positive part 91 of the crankshaft and a negative rotating ring 97 connected to the negative part 92 of the crankshaft; the positive rotating ring 96 is frictionally connected with a positive brush 98, and the positive brush 98 is connected to the positive pole of the power supply; the negative rotating ring 97 is frictionally connected with a negative brush 99, and the negative brush 99 is connected to the negative pole of the power supply.

[0035] The A terminal 211 of the coil 21 is led out through the swing wheel shaft 32 installed on the left side of the magnet frame 1 and connected to the A carbon brush 94, and the B terminal 212 of the coil 21 is led out through the swing wheel shaft 32 installed on the right side of the magnet frame 1 and connected to the B carbon brush 95.

[0036] The present invention specifically works as follows:

[0037] First, unlock the shutdown magneto-electric power position-locking safety switch 8, so that the helical teeth 81 of the shutdown magneto-electric power position-locking safety switch 8 move backward and completely separate from the helical teeth 71 on the flywheel 7, so that the flywheel 7 and the crankshaft 5 can rotate flexibly. At this time, turn on the power supply again to energize the coil 21 to generate Ampere force. Assume that the current direction of the power supply is the positive pole of the power supply - positive pole brush 98 - positive pole swivel 96 - positive pole part 91 of the crankshaft - A carbon brush 94 - coil 21 - B carbon brush 95 - negative pole part 92 of the crankshaft - negative pole swivel 97 - negative pole brush 99 - negative pole of the power supply. At this time, the coil slide 2 moves downward to drive the air-conditioning compressor 4 to do work for suction, and at the same time, the coil slide 2 also drives the crankshaft 5 through the connecting rod 6 to drive the flywheel 7 to rotate. When the coil carriage 2 reaches the lower vertex, the A carbon brush 94 is separated from the positive part 91 of the crankshaft, the B carbon brush 95 is separated from the negative part 92 of the crankshaft, and the A carbon brush 94 and the B carbon brush 95 are combined with the insulating block 93. At this time, the original current of the coil 21 is cut off and it is in a non-powered state, so the Ampere force disappears. However, due to the inertia of the flywheel 7, it will continue to rotate and drive the crankshaft 5 to rotate, so that the A carbon brush 94 and the B carbon brush 95 are separated from the insulating block 93, and the A carbon brush 94 and the B carbon brush 95 are reconnected with the positive part 91 of the crankshaft and the negative part 92 of the crankshaft, and the positions are exchanged. At this time, the current is connected again, and its direction is: positive pole of the power supply - positive brush 98 - positive swivel 96 - positive part 91 of the crankshaft - B

[0038] Carbon brush 95—coil 21—A carbon brush 94—negative part of crankshaft 92—negative rotating ring 97—negative brush 99—negative pole of power supply. At this time, the direction of the current flowing through coil 21 is opposite to the original current direction, and the direction of the Ampere force generated is also opposite. Therefore, the coil carriage 2 moves upward, pushing the air-conditioning compressor 4 to compress and do work, and at the same time drives the flywheel 7 to rotate through the connecting rod 6 and the crankshaft 5. When the air-conditioning compressor 4 is close to the maximum compression work efficiency, the flywheel 7 pushes the coil carriage 2 back through the crankshaft 5 and the connecting rod 6 due to inertia to do work on the air-conditioning compressor 4. When the coil carriage 2 reaches the top of the stroke, the compression work is also completed. At this time, the A carbon brush 94 is separated from the negative part of the crankshaft 92, and the B carbon brush 95 is disconnected from the positive part of the crankshaft 91. The A carbon brush 94 and the B carbon brush 95 are combined with the insulating block 93 to complete the process of de-energizing the coil 21 again. Similarly, the flywheel 7 and the crankshaft 5 will still rotate, and the opposite current is connected again to make the coil 21 energized and move downward to do work. So the automatic switching current works continuously in a cycle. After the shutdown, the magneto-electric power position-holding safety switch 8 will be opened to allow the coil carriage 2 of the magneto-electric power machine to stop at a quarter or three quarters of its stroke, so that the next startup can work normally.

[0039] The best embodiment of the present invention has been described, and various changes or modifications made by those skilled in the art will not depart from the scope of the present invention.
