[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] As Figures 1 - 6 shown:

[0028] A decorative article includes a base 1 and a support frame 2 installed on the top of the base 1. The top of the support frame 2 is rotatably connected to a lower swing piece 6. The shape of the lower swing piece 6 can be diverse and is in the shape of a pirate ship in this device. The top end of the support frame 2 is rotatably connected to a rotating shaft 3. A part of the outer surface of the rotating shaft 3 is fixedly connected with a connecting piece 4, and the other part of the outer surface of the rotating shaft 3 is rotatably connected with a bush 8;

[0029] One end of the connecting piece 4 is fixedly connected with a lower swing piece 6 through a hanging bracket 5. A permanent magnetic block 12 is fixedly connected to the central position at the bottom of the lower swing piece 6. A driving device is arranged inside the base 1;

[0030] There are two types of driving devices. One is an electromagnetic generator 13 that can generate an electromagnetic field with the same magnetic pole as the permanent magnetic block 12 when energized. The electromagnetic coil 14 of the electromagnetic generator 13 is located below the permanent magnetic block 12. The electromagnetic generator is a well-known technology in the field of electronics. After being connected to a power source, a corresponding magnetic field is generated on its electromagnetic coil 14, forming a same-sex repulsion with the permanent magnet on the lower swing piece. With a certain external force to drive the lower swing piece to pre-swing, under the interaction of the magnetic force and the self-gravity of the lower swing piece, the lower swing piece continuously rotates.

[0031] Another way is to have a coil 16 inside the base 1, and the coil 16 is connected to an alternating current power supply. Under the interaction between the permanent magnet block 12 and the energized coil, the lower swing member 6 rotates continuously. A controller 15 is provided inside the base 1, and the coil 16 is electrically connected to the controller 15 for controlling the magnitude of the current in the coil. After being connected to the power supply, since an alternating current power supply is applied, the coil generates a changing magnetic field in its electromagnetic coil, generating a changing magnetic field, which generates a changing electromagnetic force with the permanent magnet block 12 of the magnet. With a certain external force to drive the lower swing member to pre-swing, under the interaction of the magnetic force and the self-gravity of the lower swing member, the lower swing member rotates continuously.

[0032] One end of the outer side of the bushing 8 is fixedly connected with an upper swing member 9, and a magnet bracket 7 is fixedly installed on the outer side of one end of the hanger 5. Permanent magnets 11 are fixedly connected to the outer surfaces at the corresponding positions of the magnet bracket 7 and the upper swing member 9 and the magnetic forces repel each other.

[0033] In this embodiment: By energizing the driving device, a magnetic field will be generated after the driving device is energized. The magnetic field of the driving device repels the magnetic force of the permanent magnet 12 at the bottom of the lower swing member 6. That is to say, the magnetic repulsion force will give the lower swing member 6 a thrust to the left or right. First, push the lower swing member 6 by hand. The lower swing member 6 will rotate around the rotating shaft 3 through the connection between the hanger 5 and the connecting member 4, so that the lower swing member 6 is lifted by a certain distance, thereby enabling the lower swing member 6 to obtain gravitational potential energy. This is the initial energy. Then, release the hand pushing the lower swing member 6. The lower swing member 6 starts to swing. When the lower swing member 6 approaches the electromagnet, the magnetic repulsion force will provide an upward repulsive force when the lower swing member 6 approaches the electromagnet, which is opposite to the direction of gravity. This will cause the swing amplitude of the lower swing member 6 to increase to a certain extent. For example, originally, without the action of the magnetic repulsion force, the distance from the highest point to the lowest point of the lower swing member 6 is A. Under the action of the magnetic repulsion force, this distance may increase to A + ΔA (ΔA is the increase in the swing amplitude brought by the magnetic repulsion force). However, whether the swing amplitude of the lower swing member 6 will increase also depends on the initial motion state of the lower swing member 6 and the magnitude and direction of the magnetic repulsion force. For example, as the lower swing member 6 gradually approaches the electromagnet, the magnetic repulsion force gradually increases. The direction of this magnetic repulsion force is opposite to the direction of gravity and will offset the action of gravity to a certain extent. If the increase amplitude of the magnetic repulsion force is large enough, it may cause the resultant acceleration of the lower swing member 6 to be upward, resulting in an increase rather than a decrease in speed. Moreover, even if the magnetic repulsion force does not make the resultant acceleration upward, as long as the component of the magnetic repulsion force in the motion direction of the lower swing member 6 is the same as the motion direction, it will also do positive work on the lower swing member 6, thereby increasing the speed of the lower swing member 6. For example, when the lower swing member 6 approaches the magnet on the base 1 at a certain angle, the magnetic repulsion force can be decomposed into two component forces perpendicular and parallel to the swing direction. If the component force parallel to the swing direction is the same as the swing direction, it will accelerate the lower swing member 6. On the contrary, if the initial motion direction of the lower swing member 6 has a large angle with the direction of the magnetic repulsion force, such that the component of the magnetic repulsion force in the motion direction is opposite to the motion direction, then in this case, the speed of the lower swing member 6 will decrease. Generally speaking, affected by the magnetic repulsion force, the swing speed of the lower swing member 6 is variable and has a certain degree of ornamental value;

[0034] When the lower swing member 6 swings, the lower swing member 6 will drive the magnet bracket 7 to swing. The magnet bracket 7 will drive the permanent magnet 11 fixed thereto to swing. A magnetic repulsion force will be generated between this permanent magnet 11 and the permanent magnet 11 fixed on the upper swing member 9. Affected by the magnetic repulsion force, when the lower swing member 6 swings, it will affect the swing of the upper swing member 9. Since the swing speed of the lower swing member 6 is variable, the swing of the upper swing member 9 will be affected by the swing of the lower swing member 6. However, the swing speed of the upper swing member 9 is not synchronized with that of the lower swing member 6 and has a certain degree of ornamental value.

[0035] Furthermore;

[0036] In an alternative embodiment, a counterweight 10 is fixedly connected to the outer side of the other end of the bushing 8. By the weight of the counterweight 10, the position of the center of gravity of the system composed of the counterweight 10 and the upper swing member 9 can be changed.

[0037] In an alternative embodiment, in the system composed of the counterweight 10 and the upper swing member 9, its center of gravity is located at the axis center of the rotating shaft 3.

[0038] In this embodiment: Since the center of gravity of the system composed of the counterweight 10 and the upper swing member 9 is located at the axis center of the rotating shaft 3, when the upper swing member 9 rotates around the rotating shaft 3, it is not affected by gravity. The swing of the lower swing member 6 will cause the upper swing member 9 to rotate rather than simply swing. The rotation direction of the upper swing member 9 is affected by the swing of the lower swing member 6. At the same time, when the upper swing member 9 changes its rotation direction, it will also affect the lower swing member 6, so that the swing of the lower swing member 6 and the rotation of the upper swing member 9 are in a state that is not easily predictable and is more ornamental.

[0039] In an alternative embodiment, in the system composed of the counterweight 10 and the upper swing member 9, its center of gravity is located between the axis center of the rotating shaft 3 and the free end of the upper swing member 9.

[0040] In this embodiment: When the center of gravity of the system composed of the counterweight 10 and the upper swing member 9 is located between the axis center of the rotating shaft 3 and the free end of the upper swing member 9, the following situations will occur:

[0041] 1. When the lower swing member 6 applies an external force to raise to a high height, the lower swing member 6 will directly cross over the electromagnet. During this process, the upper swing member 9 will rotate.

[0042] 2. As the lower swing member 6 continues to move, the initial gravitational potential energy is continuously consumed until it is affected by the magnetic repulsive force and cannot cross over the electromagnet.

[0043] 3. As the lower swing member 6 continues to move, the initial gravitational potential energy is continuously consumed until it is affected by the magnetic repulsive force and cannot cross over the electromagnet. Then, the upper swing member 9 in the rotating state continues to rotate (this is because the lower swing member 6 and the upper swing member 9 rotate out of sync with a certain time difference). Affected by the magnetic repulsive force between the permanent magnet 11 fixed to the upper swing member 9 and the permanent magnet 11 on the magnet bracket 7, the kinetic energy of the rotation of the upper swing member 9 will be applied to the lower swing member 6 through the magnetic repulsive force, so that the lower swing member 6 can cross over the electromagnet (it is required that the swing direction of the lower swing member 6 is the same as the rotation direction of the upper swing member 9).

[0044] 4. As the lower swing member 6 continues to move, the initial gravitational potential energy is continuously consumed until it cannot cross the electromagnet under the influence of magnetic repulsion. The upper swing member 9 in a rotating state continues to rotate. Under the influence of the magnetic repulsion between the permanent magnet 11 fixed to the upper swing member 9 and the permanent magnet 11 on the magnet support 7, the kinetic energy of the rotation of the upper swing member 9 will be applied to the lower swing member 6 through magnetic repulsion. When the kinetic energy of the rotation of the upper swing member 9 is insufficient, the lower swing member 6 still cannot cross the electromagnet. At this time, the upper swing member 9 will rotate in the reverse direction;

[0045] Thus, the movements of the lower swing member 6 and the upper swing member 9 are in an irregular state.

[0046] Furthermore, a battery chamber for placing a battery and a power socket for plugging in a power cord are provided on the base 1. The power input ends of the driving device are respectively connected to the battery chamber and the power socket, realizing the selection of two power supply methods and making the use more flexible.

[0047] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
