The present disclosure provides a suspended galaxy device, as illustrated inFIGS. 1-3, 8 and 9, including: a drive component1, a star component2, at least one planet component3and an orbit component4.

The star component2includes a star model21. The planet component3includes a rotation portion32that is transmissively connected to the drive component1and rotatable about the star component2, a planet holder33and a planet model31. The orbit component4includes at least one annular orbit41corresponding to the at least one planet component3.

The planet holder33is disposed on the rotation portion32, and the annular orbit41corresponds to a motion track of the planet holder33; the planet holder33, the annular orbit41and the planet model31are all magnetic such that the planet model31is suspended between the planet holder33and the annular orbit41.

The drive component1drives the rotation portion32to rotate about the star model21, thereby causing the planet holder33on the rotation portion32to rotate. Driven by the magnetic force between the planet holder33and the planet model31, the planet model31also rotates with the planet holder33, thus, the planet model31is rotated about the star model21in 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 inFIGS. 1-3, including: a drive component1, a star component2, at least one planet component3and an orbit component4.

The star component2includes a star model21. The planet component3includes a rotation portion32that is transmissively connected to the drive component1and rotatable about the star component21, a planet holder33and a planet model31. The orbit component4includes at least one annular orbit41corresponding to the at least one planet component3.

The planet holder33is disposed on the rotation portion32, the annular orbit41is located above the planet holder33, and the annular orbit41corresponds to a motion track of the planet holder33; the planet holder33, the annular orbit41and the planet model31are all magnetic. For example, the annular orbit41and the planet model31are attracted to each other, and the planet holder33and the planet model31are attracted to each other too, the attraction between the annular orbit41and the planet model31suspends the planet model31, and the attraction between the planet holder33and the planet model31allows the planet model31to rotate with the planet holder33.

For example, in a direction perpendicular to a plane in which the motion track of the planet holder33is located, the planet holder33, the planet model31and the annular orbit41are sequentially arranged. For example, the motion track of the planet holder33is a circle, and the plane in which the motion track of the planet holder31is located is the plane in which the circle is located.

The drive component1drives the rotation portion32to rotate about the star model21, thereby causing the planet holder33on the rotation portion32to rotate. Driven by the magnetic force between the planet holder33and the planet model31, the planet model31also rotates with the planet holder33, thus, the planet model31is rotated about the star model21in 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 components3. The orbit component4includes a plurality of annular orbits41, and the plurality of annular orbits41are 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 model31is provided with a first magnet5interacting with the planet holder33and a second magnet6interacting with the annular orbit41.

For example, in some embodiments of the present disclosure, as illustrated inFIG. 2, the annular orbit41is above the planet holder33, the first magnet5and the second magnet6are respectively arranged at a lower position and a higher position along a vertical axis in which a gravity center of the planet model31is located, and the gravity center of the planet model31is biased toward a side of the first magnet5that is arranged at the lower position.

In some embodiments of the present disclosure, the gravity of the planet model31is always biased toward the side of the magnet that is arranged at the lower position, and under the action of gravity, the first magnet5and the second magnet6in the planet model31can quickly return to the position state respectively opposite to the planet holder33and the annular orbit41, so that the planet model31is quickly adjusted to an equilibrium state.

As illustrated inFIG. 2, when the planet model31is in equilibrium, the first magnet5is located below the planet model31and is opposite to the planet holder33, and the second magnet6is located above the planet model31and is opposite to the annular orbit41. The planet model31is disturbed during the suspension to revolve on its own axis, so that the orientation form the first magnet5to the planet holder33changes, and the orientation from the second magnet6to the annular orbit41changes, and the equilibrium state of the planet model31is destroyed. Because the gravity center of the planet model31is biased toward the side of the first magnet5located at the lower position, at this time, under the action of the gravity of the planet model31itself, the planet model31quickly returns to the original orientation relationship, so that the first magnet5is located below the planet model31, the second magnet6is located above the planet model31, and the planet model31returns to the equilibrium state.

There are a plurality of manners in which the gravity center of the planet model31is always biased toward the side of the magnet at the lower position. In some embodiments of the present disclosure, the weights of the first magnet5and the second magnet6are different, as illustrated inFIG. 2, the first magnet5and the second magnet6are respectively arranged at a lower position and a higher position along a vertical axis in which the gravity center of the planet model31is located, and the weight of the first magnet5is larger than that of the second magnet6, so that the gravity center of the planet model31is biased toward the side of the magnet at the lower position. Of course, it is also possible to add other weights on the side of the magnet at the lower position of the planet model31, so that the gravity center of the planet model31is biased toward this side; or, the upper and lower sides of the planet model31are made of materials of different densities, so that the gravity center of the planet model31is biased toward the side of the magnet at the lower position.

For example, the drive component1provided by some embodiments of the present disclosure includes: a gear set11, the gear set11includes a power shaft gear111and at least one transmission shaft gear112. The power shaft gear111can engage with the transmission shaft gear112through a plurality of gears, or can directly engage with the transmission shaft gear112. Each rotation portion32is provided with an internal gear321, and the internal gear321of each rotation portion32is engaged with each of the at least one transmission shaft gear112in the gear set11.

In the suspended galaxy device provided by embodiment one of the present disclosure, there are a plurality of planet components3, so that there are a plurality of planet models31, and the revolution period of each planet model31around the star model21may be different. In one embodiment of the present disclosure, by changing the gear ratio of a set of a transmission shaft gear112and an internal gear321that are engaged with each other, the angular velocity of the corresponding planet model31can be changed, thereby the revolution period of the planet model31is changed, and finally each planet model31has a corresponding revolution period.

For example, the gear set11provided by some embodiments of the present disclosure includes a power shaft113and a transmission shaft114that are both vertically disposed, the power shaft gear111is fixedly connected to the power shaft113, and the transmission shaft gear112is fixedly connected to the transmission shaft114. For example, in some embodiments of the present disclosure, a plurality of transmission shaft gears112can be fixed along an axial direction of a transmission shaft114, the power shaft gear111only needs to engage with one of the transmission shaft gears112, so that the plurality of transmission shaft gears112can be rotated at the same time. Correspondingly, a plurality of rotation portions32are arranged along an axial direction of a power shaft113, and the internal gear321of each rotation portion32is engaged with the corresponding transmission shaft gear112.

For example, the rotation portion32provided by some embodiments of the present disclosure includes: a connection rod322and the internal gear321. One end of the connection rod322is connected to the internal gear321, and the other end of the connection rod322is connected to the planet holder33.

For example, the drive component1provided by some embodiments of the present disclosure includes: a motor12that is transmissively connected to the power shaft gear111. For example, in some embodiments of the present disclosure, as illustrated inFIG. 4, the output shaft of the motor12is fixed with a first bevel gear13, the power shaft113is fixed with a second bevel gear14, and the first bevel gear13and the second bevel gear14are engaged with each other to realize a transmission connection of the motor12to the power shaft gear111.

For example, the star component2provided by some embodiments of the present disclosure further includes a star holder22. The orbit component4further includes a center orbit42corresponding to the star holder22. The star holder22, the center orbit42and the star model21are all magnetic, so that the star model21is suspended between the star holder22and the center orbit42.

For example, in some embodiments of the present disclosure, the center orbit42and the star model21are attracted to each other, and the star holder22and the star model21are attracted to each other too. Or, the center orbit42and the star model21are attracted to each other, and the star holder22and the star model21are repelled from each other.

For example, the star model21is provided with the first magnet5interacting with the star holder22, and the second magnet6interacting with the center orbit42. For example, in some embodiments of the present disclosure, the center orbit42is located above the star holder22, the first magnet5and the second magnet6are respectively arranged at a lower position and a higher position along a vertical axis in which a gravity center of the star model21is located, and the gravity center of the star model21is biased toward a side of the first magnet5that is arranged at the lower position.

For example, the suspended galaxy device provided by some embodiments of the present disclosure further includes a housing7, as illustrated inFIG. 3, the drive component1, the star component2and the planet component3are all located in the housing7.

The housing7includes a lower housing71, an annular glass shield72and an upper housing73, and the three enclose a closed space. The housing7is further provided with a first partition8and a second partition9that is disposed above the first partition8, and both the star model21and the planet model31are located between the first partition8and the second partition9. For example, the first partition8and the second partition9are respectively located at the upper and lower sides of the annular glass shield72. For the observer, only the star model21and the planet model31suspended in the space between the first partition8and the second partition9can be seen through the annular glass cover72, the sense of reality of the simulation is further enhanced.

For example, for the entire housing7, the first partition8and the second partition9divide the interior of the housing7into three portions, and the portion of the side wall of the housing7between the first partition8and the second partition9is 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 component1, the star component2, and the at least one planet component3are on a side of the first partition8away from the second partition9, and the orbit component4is on a side of the second partition away from the first partition8. For example, a portion of the housing7on the outside of the first partition8and the second partition9can be opaque, so that the drive component1, the star component2, the at least one planet component3and the orbit component4can 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 inFIG. 3, the star holder22and the planet holder33are located below the first partition8, and disposed inside the space between the lower housing71and the first partition8; the annular orbit41and a gravity portion are located above the second partition9, and disposed inside the space between the upper housing73and the second partition9.

For example, as illustrated inFIG. 5andFIG. 6, the first partition8is provided with a center groove81and at least one annular groove82, the center groove81corresponds to the star model21, the at least one annular groove82corresponds to the motion track of the planet model31. When the suspended galaxy device is stopped, the suspended state of the star model21and the planet model31is terminated, and the star model21can fall into the center groove81, and the planet model31can fall into the corresponding annular groove82. For example, in some embodiments of the present disclosure, there are a plurality of annular grooves82, and the plurality of annular grooves82are sequentially nested from the inside to the outside, and each annular groove82corresponds to a planet model31.

For example, in some embodiments of the present disclosure, each annular groove82can be provided with at least one concave pit that is at intervals. When the suspended galaxy device is stopped, the planet model31falls into the corresponding annular groove82, and then moves into a certain concave pit, so that the position of the planet model31is finally fixed to prevent the planet model31from freely moving within the annular groove82. Of course, if when the suspended galaxy device is stopped, the planet model31is just above a certain concave pit of the corresponding annular groove82, the planet model31can 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 inFIG. 7, the control component includes: an electrically connected sensor10, a processor20and a power supply device30.

The sensor10is configured to detect a change in a magnetic field caused by a change in distance between the planet holder33and the planet model31, and feed back corresponding change information.

The processor20is configured to generate and transmit a current compensation command according to the change information.

The power supply device30is configured to output a compensation current to a coil within the planet holder33according to the current compensation command, to adjust the magnetic field between the planet holder33and an upper orbit such that the planet model31is brought back to a suspended state.

When the planet model deviates from the equilibrium position, the distance between the planet holder33and the planet model31changes, causing a change in the magnetic field between the planet holder33and the planet model31, the sensor10can detect the change in the magnetic field and feed back corresponding information to the processor20, the processor20generates and transmits a current compensation command to the power supply device30according to the change information, the power supply device30outputs a compensation current to a coil within the planet holder33according to the current compensation command, to adjust the magnetic field between the planet holder33and an upper orbit such that the planet model31is brought back to a suspended state.

For example, in some embodiments of the present disclosure, the sensor10is 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.

As illustrated inFIG. 8andFIG. 9, the annular orbit41is located below the planet holder33, the annular orbit41and the planet model31are repelled from each other, and the planet holder33and the planet model31are attracted to each other. The repelling force between the annular orbit41and the planet model31suspends the planet model31, and the attraction between the planet holder33and the planet model31allows the planet model31to rotate with the planet holder33. In the suspended galaxy device illustrated inFIG. 8andFIG. 9, compared with the above embodiments, the annular orbit41, the planet model31, and the planet holder33is arranged in the reverse order.

For example, in the embodiments of the present disclosure, “upper” or “above” refers to the direction away from the ground when the suspended galaxy device is placed on a level ground, and “lower” or “below” refers to the direction near the ground when the suspended galaxy device is placed on the level ground.

For example, in some embodiments of the present disclosure, as illustrated inFIG. 8, in the planet model31, the first magnet5and the second magnet6are respectively arranged at a higher position and a lower position along a vertical axis in which the gravity center of the planet model31is located, the first magnet5and the planet holder33are attracted to each other, and the second magnet6and the annular orbit41are repelled from each other, and the gravity center of the planet model31is biased toward the side of the second magnet6that is arranged at the lower position. For example, the weight of the second magnet6is larger than that of the first magnet5, so that the gravity center of the planet model31is biased toward the side of the magnet that is arranged at the lower position.

For example, as illustrated inFIG. 9, the star holder22and the planet holder33are located above the second partition9, and disposed inside the space between the upper housing73and the second partition9; the annular orbit41and the gravity portion are located below the first partition8, and disposed inside the space between the lower housing71and the first partition8.

For example, the drive component1, the star component2, and the at least one planet component3are disposed on a side of the second partition9away from the first partition8, and the orbit component4is disposed on a side of the first partition8away from the second partition9.

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.

The gravity center of the planet model provided by the embodiments of the present disclosure 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 and the second magnet in the planet model can quickly return to the position state respectively opposite to the planet holder and the annular orbit, so that the planet model is quickly adjusted to an equilibrium state.

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.

The suspended galaxy device provided by the embodiments of the present disclosure further includes the housing, the housing is further provided with a first partition and a second partition that is disposed above the first partition, the first partition and the second partition are respectively located at the upper and lower sides of the annular glass shield, and the star model and the planet model are located between the first partition and the second partition. For the observer, only the star model and the planet model suspended in the space between the first partition and the second partition can be seen through the annular glass cover, so that the sense of reality of the simulation is further enhanced.

What have been described above are only exemplary implementations of the present disclosure, and is not intended to limit the protection scope of the present disclosure, and the protection scope of the present disclosure is determined by the appended claims.
