The drive component 1 drives the rotation portion 32 to rotate about the star model 21, thereby causing the planet holder 33 on the rotation portion 32 to rotate. Driven by the magnetic force between the planet holder 33 and the planet model 31, the planet model 31 also rotates with the planet holder 33, thus, the planet model 31 is rotated about the star model 21 in a suspended state, and the suspended galaxy device is closer to the situation of the celestial bodies in the universe, and has a strong sense of reality and high interest.
Some embodiments of the present disclosure provide a suspended galaxy device, as illustrated in
The star component 2 includes a star model 21. The planet component 3 includes a rotation portion 32 that is transmissively connected to the drive component 1 and rotatable about the star component 21, a planet holder 33 and a planet model 31. The orbit component 4 includes at least one annular orbit 41 corresponding to the at least one planet component 3.
The planet holder 33 is disposed on the rotation portion 32, the annular orbit 41 is located above the planet holder 33, and the annular orbit 41 corresponds to a motion track of the planet holder 33; the planet holder 33, the annular orbit 41 and the planet model 31 are all magnetic. For example, the annular orbit 41 and the planet model 31 are attracted to each other, and the planet holder 33 and the planet model 31 are attracted to each other too, the attraction between the annular orbit 41 and the planet model 31 suspends the planet model 31, and the attraction between the planet holder 33 and the planet model 31 allows the planet model 31 to rotate with the planet holder 33.
For example, in a direction perpendicular to a plane in which the motion track of the planet holder 33 is located, the planet holder 33, the planet model 31 and the annular orbit 41 are sequentially arranged. For example, the motion track of the planet holder 33 is a circle, and the plane in which the motion track of the planet holder 31 is located is the plane in which the circle is located.
The drive component 1 drives the rotation portion 32 to rotate about the star model 21, thereby causing the planet holder 33 on the rotation portion 32 to rotate. Driven by the magnetic force between the planet holder 33 and the planet model 31, the planet model 31 also rotates with the planet holder 33, thus, the planet model 31 is rotated about the star model 21 in a suspended state, and the suspended galaxy device is closer to the situation of the celestial bodies in the universe, and has a strong sense of reality and high interest.
In the suspended galaxy device according to the above embodiment, there are a plurality of planet components 3. The orbit component 4 includes a plurality of annular orbits 41, and the plurality of annular orbits 41 are sequentially nested from the inside to the outside, so that a celestial system having a plurality of planets can be simulated.
For example, the planet model 31 is provided with a first magnet 5 interacting with the planet holder 33 and a second magnet 6 interacting with the annular orbit 41.
For example, in some embodiments of the present disclosure, as illustrated in
In some embodiments of the present disclosure, the gravity of the planet model 31 is always biased toward the side of the magnet that is arranged at the lower position, and under the action of gravity, the first magnet 5 and the second magnet 6 in the planet model 31 can quickly return to the position state respectively opposite to the planet holder 33 and the annular orbit 41, so that the planet model 31 is quickly adjusted to an equilibrium state.
As illustrated in
There are a plurality of manners in which the gravity center of the planet model 31 is always biased toward the side of the magnet at the lower position. In some embodiments of the present disclosure, the weights of the first magnet 5 and the second magnet 6 are different, as illustrated in
For example, the drive component 1 provided by some embodiments of the present disclosure includes: a gear set 11, the gear set 11 includes a power shaft gear 111 and at least one transmission shaft gear 112. The power shaft gear 111 can engage with the transmission shaft gear 112 through a plurality of gears, or can directly engage with the transmission shaft gear 112. Each rotation portion 32 is provided with an internal gear 321, and the internal gear 321 of each rotation portion 32 is engaged with each of the at least one transmission shaft gear 112 in the gear set 11.
In the suspended galaxy device provided by embodiment one of the present disclosure, there are a plurality of planet components 3, so that there are a plurality of planet models 31, and the revolution period of each planet model 31 around the star model 21 may be different. In one embodiment of the present disclosure, by changing the gear ratio of a set of a transmission shaft gear 112 and an internal gear 321 that are engaged with each other, the angular velocity of the corresponding planet model 31 can be changed, thereby the revolution period of the planet model 31 is changed, and finally each planet model 31 has a corresponding revolution period.
For example, the gear set 11 provided by some embodiments of the present disclosure includes a power shaft 113 and a transmission shaft 114 that are both vertically disposed, the power shaft gear 111 is fixedly connected to the power shaft 113, and the transmission shaft gear 112 is fixedly connected to the transmission shaft 114. For example, in some embodiments of the present disclosure, a plurality of transmission shaft gears 112 can be fixed along an axial direction of a transmission shaft 114, the power shaft gear 111 only needs to engage with one of the transmission shaft gears 112, so that the plurality of transmission shaft gears 112 can be rotated at the same time. Correspondingly, a plurality of rotation portions 32 are arranged along an axial direction of a power shaft 113, and the internal gear 321 of each rotation portion 32 is engaged with the corresponding transmission shaft gear 112.
For example, the rotation portion 32 provided by some embodiments of the present disclosure includes: a connection rod 322 and the internal gear 321. One end of the connection rod 322 is connected to the internal gear 321, and the other end of the connection rod 322 is connected to the planet holder 33.
For example, the drive component 1 provided by some embodiments of the present disclosure includes: a motor 12 that is transmissively connected to the power shaft gear 111. For example, in some embodiments of the present disclosure, as illustrated in
For example, the star component 2 provided by some embodiments of the present disclosure further includes a star holder 22. The orbit component 4 further includes a center orbit 42 corresponding to the star holder 22. The star holder 22, the center orbit 42 and the star model 21 are all magnetic, so that the star model 21 is suspended between the star holder 22 and the center orbit 42.
For example, in some embodiments of the present disclosure, the center orbit 42 and the star model 21 are attracted to each other, and the star holder 22 and the star model 21 are attracted to each other too. Or, the center orbit 42 and the star model 21 are attracted to each other, and the star holder 22 and the star model 21 are repelled from each other.
For example, the star model 21 is provided with the first magnet 5 interacting with the star holder 22, and the second magnet 6 interacting with the center orbit 42. For example, in some embodiments of the present disclosure, the center orbit 42 is located above the star holder 22, the first magnet 5 and the second magnet 6 are respectively arranged at a lower position and a higher position along a vertical axis in which a gravity center of the star model 21 is located, and the gravity center of the star model 21 is biased toward a side of the first magnet 5 that is arranged at the lower position.
For example, the suspended galaxy device provided by some embodiments of the present disclosure further includes a housing 7, as illustrated in
The housing 7 includes a lower housing 71, an annular glass shield 72 and an upper housing 73, and the three enclose a closed space. The housing 7 is further provided with a first partition 8 and a second partition 9 that is disposed above the first partition 8, and both the star model 21 and the planet model 31 are located between the first partition 8 and the second partition 9. For example, the first partition 8 and the second partition 9 are respectively located at the upper and lower sides of the annular glass shield 72. For the observer, only the star model 21 and the planet model 31 suspended in the space between the first partition 8 and the second partition 9 can be seen through the annular glass cover 72, the sense of reality of the simulation is further enhanced.
For example, for the entire housing 7, the first partition 8 and the second partition 9 divide the interior of the housing 7 into three portions, and the portion of the side wall of the housing 7 between the first partition 8 and the second partition 9 is transparent. Therefore, the suspended state of the planet model between the first partition and the second partition is seen by the observer.
For example, the drive component 1, the star component 2, and the at least one planet component 3 are on a side of the first partition 8 away from the second partition 9, and the orbit component 4 is on a side of the second partition away from the first partition 8. For example, a portion of the housing 7 on the outside of the first partition 8 and the second partition 9 can be opaque, so that the drive component 1, the star component 2, the at least one planet component 3 and the orbit component 4 can be hided or be partially hided, and the sense of reality of observation is enhanced.
For example, in some embodiments of the present disclosure, as illustrated in
For example, as illustrated in
For example, in some embodiments of the present disclosure, each annular groove 82 can be provided with at least one concave pit that is at intervals. When the suspended galaxy device is stopped, the planet model 31 falls into the corresponding annular groove 82, and then moves into a certain concave pit, so that the position of the planet model 31 is finally fixed to prevent the planet model 31 from freely moving within the annular groove 82. Of course, if when the suspended galaxy device is stopped, the planet model 31 is just above a certain concave pit of the corresponding annular groove 82, the planet model 31 can also directly fall into the concave pit.
For example, the suspended galaxy device provided by some embodiments of the present disclosure further includes a control component, as illustrated in

The power supply device 30 is configured to output a compensation current to a coil within the planet holder 33 according to the current compensation command, to adjust the magnetic field between the planet holder 33 and an upper orbit such that the planet model 31 is brought back to a suspended state.
When the planet model deviates from the equilibrium position, the distance between the planet holder 33 and the planet model 31 changes, causing a change in the magnetic field between the planet holder 33 and the planet model 31, the sensor 10 can detect the change in the magnetic field and feed back corresponding information to the processor 20, the processor 20 generates and transmits a current compensation command to the power supply device 30 according to the change information, the power supply device 30 outputs a compensation current to a coil within the planet holder 33 according to the current compensation command, to adjust the magnetic field between the planet holder 33 and an upper orbit such that the planet model 31 is brought back to a suspended state.
For example, in some embodiments of the present disclosure, the sensor 10 is a Hall sensor.
Some other embodiments of the present disclosure further provide a suspended galaxy device, and only the differences from the above embodiments will be mainly described below, and the description of the same points will be omitted.

The drive component provided by the embodiments of the present disclosure drives the rotation portion to rotate about the star model, thereby causing the planet holder on the rotation portion to rotate. Driven by the magnetic force between the planet holder and the planet model, the planet model also rotates with the planet holder, thus, the planet model is rotated about the star model in a suspended state, and the suspended galaxy device is closer to the situation of the celestial bodies in the universe, and has a strong sense of reality and high interest.

In the suspended galaxy device provided by the embodiments of the present disclosure, it is possible that there are a plurality of planet components, so that there are a plurality of planet models, and the revolution period of each planet model around the star model may be different. By changing the gear ratio of a set of a transmission shaft gear and an internal gear that are engaged with each other, the angular velocity of the corresponding planet model can be changed, thereby the revolution period of the planet model is changed, and finally each planet model has a corresponding revolution period.
