It should be noted that：Similar label and letter represents similar terms in following attached drawing, therefore, once a certain Xiang Yi
It is defined, then it need not be further discussed in subsequent attached drawing in a attached drawing.
It should be noted that the float in each attached levitation device shown in figure is in suspended state.
Float provided by the invention includes housing and is arranged at (such as the aftermentioned implementation of the in vivo rotation torque generation device of shell
Fan in example), the rotation torque generation device includes stator (not shown in the structure chart in aftermentioned embodiment) and turns
Sub (part being fixedly connected in aftermentioned embodiment with blade), the rotor are equipped with along its circumferential equally distributed blade；Institute
It states stator and rotor coaxial sets and vertically overlapped with the central axis of float, the length edge on the blade blade face is horizontal
Direction extends, and width vertically extends, and when being rotated for blade air-flow is flowed in the horizontal direction.It can so ensure and turn
Air-flow caused by son is horizontally oriented flowing, and is equally distributed in the circumferential direction of float rotation.
Levitation device shown in Figure 1, including pedestal 1 and float 2.The levitation device is, for example, magnetic levitation system, base
Seat 1 suspends by field drives float 2.The internal structure schematic diagram of float 2 is referring to Fig. 2.
Float 2 has housing 21.Fluting 23 is provided on the side wall 22 of housing 21.Fan 24 is provided in housing 21.Wind
The rotor shaft direction of fan 24 is parallel to the central axis of float.Fan 24 includes flabellum 25.The blade face of flabellum 25 is parallel to float
Central axis.
The central axis for the illusion that the central axis of float 2 rotates for float 2 is flat in order to which float 2 is kept to rotate
Weighing apparatus, the central axis of float 2 are typically also by or close to by its center of gravity.
In the embodiment shown in fig. 1, the blade face of flabellum 25 is a flat shape, from the central axis edge fan of float 2
The outwardly extending direction of blade of leaf 25 is horizontally oriented.Alternatively the blade face of flabellum 25 and the central axis of float 2 are put down
Row.
The blade face of flabellum 25 can be a plane or a curved surface, but need that the blade face of flabellum 25 is kept to put down
Row is in the central axis or other shapes of float 2.When the variously-shaped setting on the blade face of flabellum rotates flabellum, fan
What air-flow caused by leaf rotation was horizontally oriented.
The blade face of flabellum 25 is in another example be the curved surface perpendicular to horizontal direction that cross section is S types, the blade face of flabellum 25 is prolonged
It is also (i.e. perpendicular to the central axis of float 2) in the horizontal direction to stretch direction.
The shape on any of the above flabellum blade face is met when 2 posture holding level of float, the length edge on blade blade face
Horizontal direction extends, and width vertically extends, and when being rotated for blade air-flow is flowed in the horizontal direction.
Float 2 is in suspended state, and flabellum 25 rotates generated air-flow through 23 outflow floats 2 of fluting.The air-flow is to floating
The reaction force driving float 2 that son 2 generates rotates.Those skilled in the art have been able to realize float 2 in suspended state
When keep horizontal.When flabellum 25 rotates, the air-flow that rotates generation is also and then air-flow outflow float in the horizontal direction
Be also to the reaction force of float 2 caused by 2 in the horizontal direction, so as to ensure float 2 in rotation status, float 2
It will not be subject to the air-flow reaction force of vertical direction, float 2 keeps horizontal attitude.
The active rotation of float 2 is realized by the fan 24 of float 2 itself, further enhances user experience.
Further, it is the stability that ensures float 2 when rotated in horizontal direction, that is to say and ensure the rotation of float 2 not
It is eccentric rotary, the shaft 26 of fan 24 should be overlapped with the central axis of float 2.
The float of such setting, in rotary course, the air-flow at each fluting is held in the active force of float
Same plane, and be evenly distributed.
It in this case, also can be according to existing appearance even if float 2 is not because other reasons keep rotating in the horizontal direction
State regulating measures easily realize the adjustment of posture.
Existing pose adjustment measure is, for example, that multiple coils are set on pedestal 1, by adjusting the electricity on each coil
Stream size adjusts distribution of these magnetic fields to the magnetic force of float 2 to adjust the magnetic field of these coils generation, so as to adjust floating
The posture of son 2.
When 2 run-off the straight of float, due to the air-out wind direction at all flutings on the whole all at grade, and institute
There is the outlet air at fluting to be uniformly distributed along the direction of rotation of float, chaotic irregular inclination will not occur for float 2, and then right
Its pose adjustment is more prone to.
In example shown in Fig. 2, the opening parallel of the fluting 23 on side wall 22 is in the rotational trajectory of opening side wall 23
Tangent line.Such fluting can be referred to as directly to fluting.All flutings 23 surround the central axis of float 2 with distribution.
In this way, ensure that the reaction force for the air-flow that float 2 is subject to is also equally distributed, be conducive to float 2 and keep water when rotating
Square upward stabilization.It should be noted that the quantity of such fluting should at least set two.The upper cover of float 2 does not have in fig. 2
It shows.
Further, in order to ensure that the reaction force of air-flow suffered by float 2 is uniformly distributed, the shape of all flutings 23 is identical.
In example shown in Fig. 3, two kinds of flutings are shown：One kind fluting 23A and two classes fluting 23B.One kind fluting 23A
The tangent line of the rotational trajectory of opening side wall 22 is each perpendicular to the opening of two classes fluting 23B.This two class fluting can be referred to as to cut
To fluting.
The circumferential first direction that one kind fluting 23A air stream outlets direction is rotated along float 2.First direction is, for example, the inverse time
Pin direction of rotation.By taking Fig. 3 as an example, when fan 24 rotates clockwise, the air-flow driven is through one kind fluting 23A outflows.It is all
Air-flow at one kind fluting 23A rotates the reaction force driving float 2 of float 2 counterclockwise.
The circumferential second direction that the air stream outlet direction of two classes fluting 23B is rotated along float 2.Second direction is e.g. suitable
Hour hands direction of rotation.By taking Fig. 3 as an example, when fan 24 rotates counterclockwise, the air-flow driven is through the fluting 23B outflows of two classes.Institute
There is the air-flow at two classes fluting 23B to rotate clockwise the reaction force driving float 2 of float 2.
Multiple a kind of fluting 23A are uniformly distributed around the central axis of float.In this way, the air-flow of a kind of fluting 23A of outflow
The circumferential direction rotated along float 2 is also equally distributed.In this way, float 2 is not easy to drift about in the horizontal direction.
Multiple two classes fluting 23B are uniformly distributed around the central axis of float.In this way, the air-flow of outflow two classes fluting 23B
The circumferential direction rotated along float 2 is also equally distributed.In this way, float 2 is not easy to drift about in the horizontal direction.
Further, in order to ensure that the reaction force of air-flow suffered by float 2 is uniformly distributed, the shape of all a kind of fluting 23A
Identical, the shape of all two classes fluting 23B is identical.
A kind of fluting 23A and two classes fluting 23B quantity are identical in example shown in Fig. 3.
In other example, the quantity of a kind of fluting 23A and 23B in float 2 can be different.
In other example, float 2 includes a kind of fluting 23A.
In other example, float 2 includes two classes fluting 23B.
It is enclosed construction to be also shown in figure 3 for the upper cover (being not shown in Fig. 3) of float 2 and the assembling of float 2
Flange 2F.
In some instances, float 2 further includes control circuit and driving circuit.Do not have in Fig. 2 and structure chart shown in Fig. 3
Above-mentioned control circuit and driving circuit are shown.
Shown in Figure 4, float 2 further includes control circuit 27 and driving circuit 28.Control circuit 27 is to driving circuit 28
Export control signal.The driving output of control signal control driving circuit 28.The driving of driving circuit 28 exports to control
The rotating speed of fan 24.
Such as driving circuit 28 is H-bridge drive circuit, and brush motor (being not shown in Fig. 4) is set in fan 24.Control
Circuit 27 controls the duty cycle of the drive signal exported to driving circuit 28, so as to control the rotating speed of fan 24.
The rotating speed of fan 24 rotates the torque applied to air with fan 24 and is positively correlated relation.Fan 24 is rotated to air
The torque of application and the air-flow of outflow float 2 are positively correlated relation to the anti-torque of float 2.Air-flow is to the anti-work of float 2
Relation is positively correlated with the rotary acceleration of torque and float 2.
The rotating speed of fan 24 and the rotating angular acceleration of float 2 are positively correlated relation in other words.Control circuit 27 is realized
Control to the rotating speed of fan 24, that is, realize the control to 2 rotating angular acceleration of float, and then realize and float 2 is rotated
Angular speed control.
In other example, optionally, float 2 further includes the sensor 29 being connected with control circuit 27.Sensor
29 are used to detect the angular speed or angular acceleration of the rotation of float 2.Sensor 29 is, for example, gyroscope, acceleration transducer etc..It passes
Sensor 29 exports sensing data to control circuit 27, and control circuit 27 obtains the state of the rotation of float 2 according to the sensing data.
Such as control circuit 27 obtains angular speed of rotation of float 2 etc..
Since the control circuit 27 of float 2 can obtain the rotation status of current float 2, fan 24 can be further adjusted
Rotating speed, so as to fulfill the accurate control rotated to float 2.
An example of sensor 29 provided in an embodiment of the present invention is shown in Fig. 5.
In this example, sensor 29 is specially infrared sensor 29A.In one example, infrared sensor 29A is
Infrared tube.The transmitting tube of known infrared tube sends infrared ray, the reception pipe of infrared tube receive barrier be reflected back it is red
Outside line.When the surface color difference of barrier, the infra-red intensity that infrared tube receives would also vary from.At another
In example, infrared sensor 29A corresponds to it base region and carries out infrared photography.The region of pedestal upper surface different colours is red
Different colors is shown in the image of outer sensor 29A.It can so be judged by the detection data of infrared sensor 29A
The color region of the current corresponding pedestal 1 of float 2.
Illustrated exemplified by the upper surface of pedestal 1, white area W and black region B is set.White area W and black region
B is alternately arranged around the central axis of float 2.The species of color is not limited to 2 kinds, but need to set the regions of different colours according to
Permanent order is alternately distributed.
Accordingly, infrared sensor 29A detection zone (in this example, detection zone be pedestal 1 upper surface
On a border circular areas around 2 central axis of float).Detection zone in each white area W corresponds to identical float 2
Rotation angle.Detection zone in each black region B corresponds to identical 2 rotation angle of float.
The example of corresponding foregoing infrared tube, the infrared ray that the white area W that reception pipe receives is reflected back is better than black
The infrared ray that color region B is reflected back.So control circuit 27 only needs timing high-intensity signal (or low intensity signal) to be held
The continuous time, with corresponding 2 rotation angles of float of white area W (or black region B) divided by the time, you can obtain float
The angular speed of 2 rotations.
The example of corresponding foregoing infrared photography, infrared sensor carry out white area W on pedestal 1 infrared photography and right
Imaging when black region B carries out infrared photography is also different colours.So 27 need of control circuit are more adjacent claps twice
Difference and the combination adjacent time difference taken pictures twice according to imaging, can both calculate the angular speed of the rotation of float 2.
On the premise of infrared sensor precision allows, the number that white area W and black region B are set is more, control
It is more accurate that circuit 27 calculates the angular speed that the float 2 obtained rotates.
Another example of sensor 29 provided in an embodiment of the present invention is shown in Fig. 6.
In this example, sensor 29 is specially range sensor 29B.Range sensor 29B be, for example, ultrasonic wave away from
From sensor or laser distance sensor etc..
Illustrated exemplified by the upper surface of pedestal 1, high surface region H and low surface area L is set.High surface region H and low
Surface region L surrounds the relatively low arrangement of central axis of float 2.The upper surface of high surface region H is higher than the upper table of low surface area L
Face.Height during the region of different height is not limited to 2, but the region for setting different height is needed to be alternately distributed in a fixed order.
Accordingly, (in this example, detection zone is on the upper surface of pedestal 1 to the detection zone of distance measuring sensor 29B
A border circular areas around 2 central axis of float).Detection zone in each high surface region H corresponds to identical float 2
Rotation angle.Detection zone in each low surface area L corresponds to identical 2 rotation angle of float.
Control circuit 27 only needs the distance between range sensor 29B and pedestal 1 of timing float 2 that different conditions institute is presented
Duration, with the corresponding angle of detection zone divided by short-range signal in high surface region H (or low surface area L)
(or long range signals) duration, you can obtain the angular speed that float 2 rotates.
The number that high surface region H and low surface area L is set is more, and control circuit 27 calculates the float 2 obtained and rotates
Angular speed is more accurate.
In the example shown in Fig. 6, the upper surface of pedestal 1 is provided with the high surface region H of two rings.The purpose one so designed
It is to be beauty, second is that being to allow that those skilled in the art adjust the distance sensor 29B can be on the radial direction of float 2
Row position adjusts.
Referring to described in Fig. 4, optionally, float 2 includes wireless power receiving module 2A, and pedestal 1 includes wireless power
Transmitting module 1A.Wireless power transmitting module 1A exports electric energy, wireless power receiving module 2A for wireless power receiving module 2A
For each power elements in entire float 2.
In this way, the system structure of levitation device is simpler.
