[Example 1]

2A to FIG. 3, wherein, FIG. 2A is a three-dimensional schematic diagram of a preferred embodiment of the energy-saving generator of the present invention; FIG. 2B is an exploded schematic diagram of the energy-saving generator of the present invention; Sectional view of A'.

As shown in FIG. 2A and FIG. 2B , the energy-saving generator of the present invention is a generator for connecting to an external power input mechanism (such as a motor, etc.), and then converting kinetic energy into electrical energy, and its preferred specific embodiment Including: a set of air-core coils 10, the air-core coil 10 has an annular hollow frame 11, and a magnetic induction coil 12 wound around the hollow frame 11; wherein, the center of the hollow frame 11 has a hollow part 13; a permanent magnet The rotor 20 has a permanent magnet 21 and at least one rotating shaft 22 combined with the permanent magnet 21; wherein, the permanent magnet 21 is rotatably arranged in the hollow portion 13 of the hollow coil 10, and at least one rotating shaft 22 is used for connecting to the power The input mechanism, wherein at least one rotating shaft 22 is two rotating shafts combined with the two ends of the permanent magnet 21, or a single rotating shaft (not shown) passing through the permanent magnet 21; Disposed on the side, each magnetic drive member 50 is disposed adjacent to the permanent magnet rotor 20 . The magnetic driving element 50 can be fixed on the hollow frame 11 , but not limited thereto. For example, the magnetic driving element 50 can also be arranged at any position outside the hollow coil 10 , as long as the magnetic driving element 50 can generate a magnetic force with the permanent magnet rotor 20 . .

For the convenience of description, the following paragraphs only take the aspect in which the at least one rotating shaft 22 is two rotating shafts 22 as an example, and those skilled in the art can think of the embodiment of the aspect of the single rotating shaft 22 from the description herein. Thereby, the permanent magnet 21 is rotatably arranged in the hollow portion 13 of the hollow frame 11 of the above-mentioned hollow coil 10 through the positioning function of the two rotating shafts 22, and the two rotating shafts 22 respectively pass through the two ends of the hollow frame 11; Therefore, when the permanent magnet rotor 20 rotates, the magnetic induction coil 12 of the air-core coil 10 can generate electromagnetic induction, and then the kinetic energy can be converted into electrical energy, thereby realizing power generation. The above principle of electromagnetic induction can at least be known from Ampere's right-hand rule, so the details of the principle will not be described in detail.

As shown in FIG. 2B , the magnetic induction coil 12 is composed of copper wire wound around the hollow frame 11 , and the hollow coil 10 can be arranged on any kind of equipment or motor or in an independent casing. One end of the shaft 22 of the permanent magnet rotor 20 corresponding to the permanent magnet 21 is provided with a joint portion 221 . The end of the permanent magnet 21, and then the external power input mechanism drives the permanent magnet rotor 20 to rotate. Each magnetic driving member 50 is disposed adjacent to the permanent magnet rotor 20 , and more specifically, each magnetic driving member 50 is disposed adjacent to the permanent magnet 21 of the permanent magnet rotor 20 for generating a magnetic force with the permanent magnet 21 .

As shown in FIG. 3 , viewed from the direction of the side section of the energy-saving generator, the side section is the section of the line segment AA′ in FIG. 2A , wherein the side section is parallel to the transverse section of the permanent magnet 21 , and the line segment is AA' will be perpendicular to the extending direction of the permanent magnet 21 . This embodiment includes two magnetic driving members 50, which are disposed on the left and right sides of the permanent magnet 21 of the permanent magnet rotor 20, so that the main magnetic force of each magnetic driving member 50 can conform to the rotation direction of the permanent magnet rotor 20 (for example, Rotation direction Dr1), in order to add the rotation of the permanent magnet rotor 20, but the present invention is not limited to setting the magnetic drive member 50 corresponding to the left and right sides of the permanent magnet 21 of the permanent magnet rotor 20, in other embodiments of the present invention , the magnetic drive member 50 can also be arranged corresponding to the upper and lower sides of the permanent magnet 21 of the permanent magnet rotor 20 . In addition, in other embodiments of the present invention, a plurality of magnetic driving elements 50 may also be included, and an even number is preferred, but the present invention is not limited thereto. In the present invention, the rotation direction compliant with the permanent magnet rotor 20 , such as shown in FIG. 3 , is the rotation direction Dr1 , and the rotation direction Dr1 may be counterclockwise, but the invention is not limited thereto. In other embodiments of the present invention, the rotation direction Dr1 may be a clockwise direction.

As shown in FIG. 3 , each magnetic driving member 50 has a magnetic field line starting point 55 and a farthest edge 50a away from the permanent magnet 21, wherein an extension line passing through the farthest edge 50a is defined as a first extension line e1, the magnetic field line An extension line having the shortest distance between the starting point 55 and the first extension line e1 is defined as a second extension line e2 , and the second extension line e2 does not pass through the shaft center 20 a of the permanent magnet rotor 20 . More specifically, the first extension line e1 refers to an extension line formed along the farthest edge 50a of the permanent magnet 21. Therefore, the first extension line e1 may exceed the entire energy-saving generator. Similarly, the second extension line e2 refers to an extension line formed along the shortest distance between the starting point 55 of the magnetic field line and the first extension line e1, so the second extension line e2 can also exceed the entire energy-saving generator.

In this embodiment, the magnetic driving element 50 is an electromagnet, and the magnetic polarity of each magnetic driving element 50 facing the permanent magnet 21 is the same as the magnetic polarity of the permanent magnet 21 facing each magnetic driving element 50 (for example, both are N poles). ), which are mutually exclusive. The magnetic force of the magnetic drive member 50 on the permanent magnet 21 can be regarded as a thrust, which is used to increase the rotation of the permanent magnet rotor 20 (for example, the rotation direction Dr1 ), which does not pass through the shaft of the permanent magnet rotor 20 through the second extension line e2 center 20a, so that the main magnetic force of the magnetic drive member 50 does not directly point to the shaft center 20a of the permanent magnet rotor 20, so as to achieve the purpose of adding the permanent magnet rotor 20 to rotate. In one embodiment, the force acting on the permanent magnets 21 by the oppositely disposed magnetic driving members 50 can be regarded as causing the permanent magnets 21 to produce a levitating effect, but it is not limited.

Further, in one embodiment, the outer surfaces of the permanent magnets 21 all have a single magnetic polarity, for example, they are all N poles. At this time, the magnetic polarity of each magnetic driving element 50 facing the permanent magnets 21 is also N poles.

In another embodiment, the permanent magnet 21 is a bipolar magnet. For example, one end of the permanent magnet 21 (one end in the longer extension direction) is the N pole, and the other end (the other end in the longer extension direction) is the S pole. At this time, the magnetic driving member 50 can be disposed at one end portion adjacent to the permanent magnet 21, and must have the same polarity at the end portion. For example, the magnetic driving member 50 at the end of the N-pole adjacent to the permanent magnet 21 must be N-pole, The magnetic drive member 50 adjacent to the S pole end of the permanent magnet 21 must be the S pole. In one embodiment, "disposed adjacent to the end" may be, for example, disposed adjacent to the side surface of the main axis (longer extension direction) of the permanent magnet 21, but as long as it can be achieved, it can also be disposed adjacent to the positive side of both ends of the permanent magnet 21. The front side (that is, the extending direction of the permanent magnet 21 is perpendicular to the magnetic force acting surface of the magnetic driving member 50 ), but not limited to this.

The foregoing descriptions are applicable to subsequent embodiments.

More specifically, as shown in FIG. 3 , the main magnetic force of the magnetic driving member 50 is the force acting on the permanent magnet rotor 20 by the starting point 55 of the magnetic force line, and the extension line of the force will overlap with the second extension line e2 . Therefore, if the shortest distance ds1 between the second extension line e2 and the shaft center 20a of the permanent magnet rotor 20 is 0, the main magnetic force of the magnetic driving member 50 will be directed to the shaft center 20a of the permanent magnet rotor 20, driving the permanent magnet rotor 20. The rotation effect of the magnetic rotor 20 is poor; if the shortest distance ds1 between the second extension line e2 and the shaft center 20a of the permanent magnet rotor 20 is too large, the main magnetic force of the magnetic drive member 50 cannot effectively act on the permanent magnet rotor 20. On the magnetic rotor 20, it is also disadvantageous to drive the permanent magnet rotor 20 to rotate. In this embodiment, the shortest distance ds1 between the second extension line e2 and the shaft center 20 a of the permanent magnet rotor 20 is between 0.001 and 0.005 times the radius of the permanent magnet rotor 20 . Preferably, the shortest distance ds1 between the second extension line e2 and the shaft center 20a of the permanent magnet rotor 20 is between 0.002 and 0.003 times the radius of the permanent magnet rotor 20, but the present invention is not limited thereto.

Preferably, the included angle θ1 is between 1 and 35 degrees, but the present invention is not limited thereto.

If the included angle θ1 is 0 degrees, the main magnetic force of the magnetic driving member 50 will be directed to the shaft center 20a of the permanent magnet rotor 20, resulting in a poor effect of driving the permanent magnet rotor 20 to rotate; if the included angle θ1 is greater than 45 to When the angle is 60 degrees, the main magnetic force of the magnetic driving member 50 cannot effectively act on the permanent magnet rotor 20, and it is also disadvantageous to drive the permanent magnet rotor 20 to rotate.

An extension line of is defined as a fourth extension line e4 , and the fourth extension line e4 does not pass through the shaft center 20 a of the permanent magnet rotor 20 . Since the fourth extension line e4 does not pass through the shaft center 20a of the permanent magnet rotor 20, the main magnetic force of the magnetic driving member 50 does not directly point to the shaft center 20a of the permanent magnet rotor 20, and the rotation of the permanent magnet rotor 20 can be added to reduce the external The input of mechanical energy improves the power generation efficiency.

More specifically, the magnetic driving member 50 of the present embodiment has a magnetic force line starting point 55 and a magnetic force acting direction MD1, wherein an extension line along the magnetic force acting direction MD1 and passing through the magnetic force line starting point 55 is the fourth extension line e4, and the first The four extension lines e4 do not pass through the shaft center 20 a of the permanent magnet rotor 20 . Thereby, the main magnetic force of the magnetic driving member 50 is not directed to the shaft center 20a of the permanent magnet rotor 20 directly, so that the permanent magnet rotor 20 can be added to rotate, and the power generation efficiency can be improved.

After the arrangement is adjusted, the magnetic driving member 50' has a magnetic force line starting point 55' and a magnetic force acting direction MD1', and an extension line along the magnetic force acting direction MD1' and passing through the magnetic force line starting point 55' is a fourth extension line e4', and the first The four extension lines e4' pass through the shaft center 20a of the permanent magnet rotor 20, wherein the included angle between the fourth extension line e4 and the fourth extension line e4' corresponds to the adjustment angle θ2. It should be noted that the adjustment angle θ2 described in this embodiment is used to define the included angle between the fourth extension line e4 and the fourth extension line e4'. When actually operating the energy-saving generator of the present invention, the fourth extension The line e4 still does not pass through the shaft center 20a of the permanent magnet rotor 20, so that the permanent magnet rotor 20 rotates.

In an implementation aspect of this embodiment, as shown in FIG. 8A , the magnetic driving member 50 can be rotated by using the starting point 55 of the magnetic field line as a fulcrum, so that the fourth extension line e4 ′ of the rotated magnetic driving member 50 ′ passes through the permanent magnet rotor 20 of the axis 20a, and thereby define the adjustment angle θ2. Since the present embodiment uses the starting point 55 of the magnetic field line of the magnetic driving member 50 as the fulcrum for rotation, the starting point 55' of the magnetic field line of the magnetic driving member 50' after rotation is the same as the original starting point 55 of the magnetic field line.

In another implementation aspect of this embodiment, as shown in FIG. 8B , other positions of the magnetic driving member 50 can be used as fulcrums to rotate the magnetic driving member 50 , so that the fourth extension line e4 ′ of the rotated magnetic driving member 50 ′ can be rotated. Through the shaft center 20a of the permanent magnet rotor 20, the adjustment angle θ2 is defined thereby. Since the present embodiment uses other positions of the magnetic driving member 50 as the fulcrum for rotation, for example, the point P is used as the fulcrum for rotation, therefore, the magnetic field line starting point 55' of the magnetic driving member 50' after rotation is different from the original magnetic field line starting point 55.

In this embodiment, as shown in FIG. 8A and FIG. 8B , the magnetic driving member 50 has an irregular shape, but the present invention is not limited to this. To the magnetic driving member 50 shown in FIG. 4D , or the magnetic driving member 50 of other shapes.
