Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of art display, in particular to a machine core and a dynamic art device using the same. BACKGROUND

[0002] Technology and art have always been closely linked. The development of technology has brought new media and new technology, which has liberated the physical world from the shackles of the artist's imagination, and on the other hand, the artist's free imagination has also outlined the blueprint of future technology. Sculpture is an ancient and advanced modeling art. And "dynamic sculpture (device)" is an organic combination of modern technology, industrial manufacturing and art.

[0003] Compared with works of other media, various dynamic sculpture works have always had higher traffic on the Internet due to their lively beauty. For example, the "Kafka" statue designed by Czech sculptor David Cerny and located in the square of Prague, Czech Republic, very accurately presents the jumping thoughts of the novelist Kafka. Many similar works have also been located in the cities where we live in the form of public sculptures, such as the wind-driven sculpture "Magic Tree" designed by Swiss artist Ralfonso for the sculpture park in Wuhu, etc. Some dynamic sculptures can use electric motors or servo motors to achieve activity, such as the "Sacred Fire Light" sculpture in Beijing Science and Technology Museum, etc.

[0004] However, the dynamic effects realized by the above-mentioned dynamic sculptures are mostly simple rotation or combination of rotation, which is relatively single in visual perception.

[0005] In order to give dynamic sculptures more motion changes and make them produce more different changes in visual perception, a new type of machine core structure and a dynamic art device with the machine core structure need to be developed. SUMMARY

DETAILED DESCRIPTION

[0042] In order to make the objects, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be described in detail below. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work belong to the scope of protection of the present application.

[0043] In the description of the present application, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first", "second", "third" and the like are only for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0044] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "connecting", "connecting" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0045] The technical solutions of the present application will be described in detail below in combination with the drawings.

[0046] The present application provides a movement, comprising a rotating unit and a driving unit, wherein the driving unit is used to drive the rotating unit to rotate.

[0047] Specifically, the rotating unit comprises a first rotating part 1 and a second rotating part 2 connected in rotation, wherein an angle exists between the rotating shaft of the first rotating part 1 and the rotating shaft of the second rotating part 2; the driving unit is located outside the rotating unit and comprises a first rotating driving part 3 and a second rotating driving part 4, the first rotating driving part 3 is connected with the first rotating part 1 and drives the rotation of the first rotating part 1, and at least part of the second rotating driving part 4 passes through the first rotating part 1 and drives the rotation of the second rotating part 2.

[0048] In order to ensure that the above-mentioned rotating effect can be achieved, it is necessary to set the first rotating part 1 to be a hollow structure through which at least part of the second rotating driving part 4 can pass.

[0049] Since an angle exists between the rotating shaft of the first rotating part 1 and the rotating shaft of the second rotating part 2, the core can produce different relative operating states between the first rotating part 1 and the second rotating part 2 by controlling the rotation direction and rotation speed of the first rotating part 1 and the second rotating part 2, and the second rotating part 2 produces irregular motion relative to the first rotating part 1 in visual effect, which is difficult for the viewer to quickly identify, and the diversity of the visual effect enhances the ornamental value and interest of the device.

[0050] Since an angle exists between the rotating shaft of the first rotating part 1 and the rotating shaft of the second rotating part 2, in order to ensure that the two can rotate independently and do not affect each other, as an optional embodiment, the second rotating part 2 comprises a universal joint 21, and the second rotating driving part 4 is connected with the universal joint 21 and drives the rotation of the universal joint 21.

[0051] The universal joint 21 can help to twist the rotation shaft direction at the second rotating driving part 4, so that the rotation shaft can be deflected towards the rotation shaft direction of the second rotating part 2, and the rotation of the second rotating part 2 is realized.

[0052] In the embodiment, the structure of the universal joint 21 is as shown in Figure 2 The universal joint 21 is in a flat sheet structure as a whole, and a cross-shaped through hole 211 is arranged in the middle part of the universal joint 21 and penetrates through the upper and lower sides in the thickness direction of the universal joint 21, and a connecting part 41 is arranged on the part of the second rotating driving part 4 connected with the cross-shaped through hole 211; the connecting part 41 comprises a spherical connecting core 411 and two connecting lugs 412 protruding outward from the diameter of the connecting core, the connecting core is located in the middle part of the cross-shaped through hole 211, and the connecting lugs 412 can extend into the strip-shaped grooves of the opposite two cross-shaped through holes 211; when the second rotating driving part 4 rotates and drives the rotation of the connecting part 41, the connecting lugs 412 located outside the connecting core can push the universal joint 21 to rotate relative to the first rotating part 1 through the strip-shaped grooves.

[0053] During the rotation, the universal joint 21 will swing up and down relative to the first rotating part 1 and the connecting protrusion 412 because of the angle between the rotation axis of the universal joint 21 and the rotation axis of the first rotating part 1. At this time, the strip-shaped recess will also swing down relative to the connecting protrusion 412.

[0054] Of course, the structure of the universal joint 21 is only an example and is not a limitation of the structure of the universal joint 21 in the present application. The structure of the universal joint 21 and the connecting member 41 matched therewith can also be other universal connecting structures such as "cup connection" disclosed in the prior art.

[0055] It can be understood that the effect that two rotatingly connected components rotate independently can be achieved by the above-mentioned movement core structure. When the movement core is applied to a corresponding dynamic sculpture, dynamic ornament or other dynamic art device, the corresponding dynamic art device will have a dynamic visual effect and dramatic interestingness.

[0056] Embodiment 1:

[0057] The present embodiment provides a movement core including a rotating unit and a driving unit, as shown in Figure 1 , wherein the rotating unit includes a first rotating part 1 and a second rotating part 2 which are rotatingly connected, and the driving unit includes the first rotating part 1, the second rotating part 2 and a fixed member 5.

[0058] In the present embodiment, the structure of the driving unit is described with the whole driving unit located substantially below the rotating unit, as shown in Figure 3 .

[0059] Specifically, the fixed member 5 is provided with a first slewing bearing 51 and a second slewing bearing 52 at two ends thereof along the axial direction, wherein the first slewing bearing 51 is used for connecting the first rotating part 1 and the first rotating driving member 3; the second slewing bearing 52 is used for connecting the second rotating driving member 4; a transmission shaft 42 connected with the second rotating part 2 is further provided on the axis of the fixed member 5, the lower end of the transmission shaft 42 is fixedly connected with the outer ring of the second slewing bearing 52, the upper end of the transmission shaft 42 is provided with the connecting member 41 described above and is connected with the second rotating part 2 through the connecting member 41, and the part penetrating through the first slewing bearing 51 is connected with the first slewing bearing 51 through a bearing, so as to avoid the transmission shaft 42 from shaking during rotation.

[0060] The mounting structure of the first slewing bearing 51 and the second slewing bearing 52 will be described in detail as follows:

[0061] The inner ring of the first slewing bearing 51 is connected to the fixing member 5, the lower edge of the outer ring is connected to the first rotary drive member 3, and the upper edge of the outer ring is fixedly connected to the first rotating part 1. When the first rotary drive member 3 is activated, the outer ring of the first slewing bearing 51 rotates, causing the first rotating part 1 to rotate synchronously. Similarly, the inner ring of the second slewing bearing 52 is connected to the fixing member 5, and the outer ring is connected to the second rotary drive member 4. When the second rotary drive member 4 is activated, the outer ring of the second slewing bearing 52 rotates, causing the transmission shaft 42 to rotate synchronously.

[0062] In this embodiment, the first rotary drive 3 and the second rotary drive 4 have the same structure, both being independently controllable servo motors with drive teeth. A first toothed ring 511 is formed on the outer ring of the first slewing bearing 51 near the side of the first rotary drive 3 (i.e., the lower edge of the outer ring), and the first rotary drive 3 meshes with the first toothed ring 511. A second toothed ring 521 is formed on the outer ring of the second slewing bearing 52 near the side of the second rotary drive 4, and the second rotary drive 4 meshes with the second toothed ring 521.

[0063] Furthermore, a spline 512 is formed on the outer ring of the first slewing bearing 51 on the side away from the first rotary drive member 3 (i.e., the upper edge of the outer ring), and a structure that can mate with the spline 512 is also formed at the corresponding position of the first rotating part 1. Therefore, the first rotating part 1 is engaged with the outer ring of the first slewing bearing 51 via the spline 512.

[0064] The cross-sectional structure of the drive unit, excluding connector 41, is as follows: Figure 4 As shown, at this time, the first rotation drive 3 and the second rotation drive 4 are both fixedly mounted on the fixing member 5 and can drive the first rotating part 1 and the second rotating part 2 to rotate respectively, so as to achieve complex and varied visual effects.

[0065] It should be noted that, in this embodiment, in order to ensure that the first rotating part 1 and the second rotating part 2 can rotate independently and without affecting each other, a contact plane 11 is formed on the side of the first rotating part 1 close to the second rotating part 2, and the rotation axis of the second rotating part 2 is perpendicular to the contact plane 11.

[0066] In use, the aforementioned drive shaft 42 passes through the contact plane 11 and connects with the universal joint 21. In addition, since the contact plane 11 is perpendicular to the rotation axis of the second rotating part 2, this means that there must be an angle between the contact plane 11 and the rotation axis of the first rotating part 1.

[0067] Generally speaking, the angle between the rotation axis of the first rotating part 1 and the rotation axis of the second rotating part 2 is 0 to 45°. In addition, the intersection of the extension lines of the two rotation axes must be located on the connector 41 at the top of the transmission shaft 42.

[0068] In the embodiment, the included angle is further set to be between 22.5-35°, for example, 22.5°, 30° and 35°.

[0069] Specifically, a bearing is further arranged between the first rotating part 1 and the second rotating part 2, the inner ring of the bearing is fixedly arranged on the contact plane 11, and the outer ring is fixedly connected with the universal joint 21.

[0070] In addition, in order to further enhance the connection strength between the first rotating part 1 and the second rotating part 2, in the embodiment, a fixed ring 12 is fixedly installed in the middle of the contact plane 11 by a bolt, and the bearing is sleeved outside the fixed ring 12, and the inner ring can be fixedly connected with the contact plane 11 and the fixed ring 12. The middle of the fixed ring 12 is formed with a through hole through which the transmission shaft 42 passes and does not affect the swing of the transmission shaft 42.

[0071] In order to further ensure that the movement can have a better visual effect, in addition to the contact plane 11, in the embodiment, at least part of the outer side edge of the first rotating part 1 close to the second rotating part 2 and at least part of the outer side edge of the second rotating part 2 are located on the same smooth curved surface.

[0072] As shown in Figure 1 At this time, when the second rotating part 2 rotates relative to the first rotating part 1, the rotation movement therebetween is difficult to be perceived, so when the second rotating part 2 has a non-central symmetric structure, the rotation of the second rotating part 2 relative to the first rotating part 1 can shape a more dynamic visual effect.

[0073] It can be understood that the movement structure provided in the embodiment can provide a dynamic and more dynamic visual effect by controlling the rotation direction and rotation speed of the two rotating driving members, and the visual effect of partial structure torsion, deformation or swing can be achieved by visual illusion.

[0074] Embodiment 2:

[0075] The difference between the embodiment 2 and the embodiment 1 is that:

[0076] The application provides a dynamic art device, which comprises the movement as described in any one of the above embodiments, and further comprises a decorative part 6 fixedly arranged outside the second rotating part 2, and the center of the decorative part 6 falls on the rotation shaft of the second rotating part 2.

[0077] The decorative part 6 can rotate synchronously with the rotation of the second rotating part 2, so as to cooperate with the first rotating part 1 to realize more exaggerated and obvious twisting, shaking or torsional deformation and the like in vision, so that the dynamic art device has strong dynamics, and the excellent interest and ornamental value are obtained through the diversity of observation.

[0078] Specifically, the device further comprises a fixed bottom shell 7, in which a space for installing the driving unit is reserved, and at least part of the driving unit is located in the fixed bottom shell 7.

[0079] In the embodiment, as shown in Figure 6 The lower end of the fixed bottom shell 7 is provided with a base that can be fixed on the installation plane (usually the ground), the middle part is provided with a support leg or the like for supporting the dynamic art device, and the upper part is provided with a hollow structure. The fixing member 5 in the driving unit can be fixedly connected with the hollow structure, and at this time, the first rotating unit and the second rotating unit are located in the hollow structure of the fixed bottom shell 7 and are shielded by the structure. When the driving unit is started, the first rotating unit and the second rotating unit located above it rotate, at this time, the exposed rotating unit and the decorative member 6 can form a special visual effect in a certain range on the fixed bottom shell 7 by rotating, which is similar to the irregular movement of the decorative member 6 in a certain area above the fixed bottom shell 7, further enhancing the dynamic visual effect of the dynamic art device.

[0080] In the embodiment, the dynamic art device is provided as a whole similar to an "umbrella" or a "mushroom", and the umbrella cover structure at the top is mainly composed of the second rotating part 2 and the decorative member 6.

[0081] Specifically, part of the structure of the decorative member 6 can cooperate with the second rotating part 2 to form a structure similar to a cut sphere, at this time, the decorative member 6 forms a spherical shell structure covering the second rotating part 2, and the spherical center coincides with the intersection of the rotation axes of the first rotating part 1 and the second rotating part 2.

[0082] In addition, in order to further enhance the visual effect of the decorative member 6 when rotating, the outer peripheral side can extend outward relative to the cut sphere and form a decorative flat piece 61 with a certain decorative effect.

[0083] When the second rotating part 2 rotates, the decorative flat piece 61 can rotate and produce obvious up and down swing or swing, forming a dynamic visual effect of "swaying in the wind", as shown in Figure 5 and Figure 7 As shown in Figure 8 In addition, Figure 8 The angle α in the figure represents the included angle between the rotation shaft of the first rotating part 1 and the rotation shaft of the second rotating part 2, at this time, the swing angle of the decorative flat piece is β, which is twice the angle between the two rotation shafts, that is, 2α.

[0084] Specifically, the decorative flat sheet 61 can be flat, wavy or other structures. It should be noted that the decorative flat sheet 61 and the contact plane 11 are in different planes and the two planes are non-parallel.

[0085] In order to achieve better visual effects, in the embodiment, the first rotating part 1 can be a rotationally symmetric cylindrical or frustum structure, and the second rotating part 2 and the decorative part 6 can be an axisymmetric structure. When the dynamic art device is started, the rotation direction and rotation speed of the first rotating drive 3 and the second rotating drive 4 can be controlled to provide the viewer with a visual experience of the dynamic art device in the process of twisting and deforming and swinging by using visual illusion and the special appearance of the dynamic art device.

[0086] The dynamic art device provided in the embodiment is arranged vertically on a horizontal installation plane. It should be noted that the dynamic art device can also be fixed in a horizontal direction on a vertical wall or any plane or curved surface structure that can be used for display.

[0087] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can easily think of changes or replacements within the technical range disclosed in the present application, which should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
