For example, the magnetic properties of the adjacent first electromagnetic element 21a are different from the magnetic properties of the second magnetic element 21b. Specifically, the first and second electromagnets 21a, 21a', 21b, 21b' have an electromagnet 210 and a coil 211 around the electromagnet 210, which are generated by the controller 9 controlling the coil 211 The current directions I, I'make the adjacent first electromagnetic parts 21a, 21a' and second electromagnetic parts 21b, 21b' produce different magnetism, such as N pole and S pole.

In this embodiment, the driving member 23 is supported by the blade 22 without contacting the inner side wall 20a, the outer side wall 20b, and the bottom side 20c of the groove structure 200 of the frame body 20. It should be understood that there are many ways for the driving member 23 to connect to the blade 22, such as welding, and there is no particular limitation.

Furthermore, as shown in Figure 2C, the driving member 23 is a rectangular block with a first side 23a and a second side 23b opposite to each other, and the first side 23a is configured with a plurality of first magnets such as magnets. The second side 23b is provided with a plurality of second magnetic portions 232, 232' such as magnets, so that the magnetic properties of the first magnetic portion 231, 231' are different from the magnetic properties of the second magnetic portion 232, 232'.

In the same way, the second magnetic portion 232, 232' and the first electromagnetic element 21a, 21a' repel each other due to the same pole (for example, the repulsive force f2), and the second magnetic portion 232, 232' and the second electromagnetic element 21b, 21b' Because the opposite poles attract each other (such as the attraction f1).

Therefore, as shown in Figure 2C, when the fan 2 is used, the first and second electromagnetic elements 21a, 21a', 21b, 21b' are energized, so that the driving element 23 and the guide rail assembly 21 are in Electromagnetic power (such as repulsive force f2 and attractive force f1) is simultaneously generated on the inner side wall 20a and the outer side wall 20b, so that the driving member 23 faces the target direction R along the edge of the frame 20 (as shown in Figures 2A and 2C) Move to drive the blade 22 to rotate relative to the shaft 24.

3A to 3C are schematic diagrams of the second embodiment of the fan 3 of the present invention. The difference between this embodiment and the first embodiment lies in the orientation of the bottom side 30c of the frame body 30, and the other structures and operating modes are substantially the same. Therefore, only the differences are described below, and the similarities will not be repeated.

As shown in FIGS. 3A to 3C, the inner side wall 30a and the outer side wall 30b of the groove structure 300 of the frame body 30 are facing forward and rearward, and the bottom side 30c of the groove structure 300 is along the upper, lower, left, and Surround in the right direction so that the opening of the groove structure 300 faces the shaft 24 (or the center of the frame 30).

In this embodiment, the frame 30 can be erected on a support base 3a as required, so that the fan 3 is used as a household appliance electric fan, and each blade 22 is connected to the driving member 23 to facilitate stable rotation of the blades. twenty two.

Furthermore, the fan 3 further includes a magnetic assembly 34, which includes a corresponding first magnetic member 34a and a second magnetic member 34b. For example, the first magnetic member 34a is disposed on the driving member 23, and the second magnetic member 34b is disposed on the bottom side 30c of the frame 30, so that the magnetic property of the first magnetic member 34a is the same as that of the first magnetic member 34a. The magnetism of the two magnetic members 34b repels each other, so that the driving member 23 will not contact the bottom side 30c of the frame 30. Therefore, when the blade 22 rotates, the driving member 23 can be prevented from rubbing or hitting the frame 30.

Moreover, if the magnetic component 34 is a permanent magnet group, the driving member 23 will not contact the frame 30 when the blade 22 stops rotating; if the magnetic component 34 is an electromagnet group, when the blade 22 stops rotating, The magnetic assembly 34 can be electrified so that the driving member 23 will not contact the frame 30, and the magnetic assembly 34 may also be electrified to make the driving member 23 contact the frame 30.

It should be understood that if the shaft member 24 is erected on the support base 3a, as shown in FIG. 3A', no matter if the blade 22 rotates or stops rotating, the driving member 23 will not contact the frame 30.

4A to 4B are schematic diagrams of the third embodiment of the fan 4 of the present invention. The difference between this embodiment and the second embodiment is that another fan set 4a is added, and the other structure and operation mode are roughly the same. Therefore, only the differences are described below, and the similarities are not repeated here.

As shown in Figures 4A to 4B, the fan assembly 4a includes a functional frame 40 as a track, the guide rail assembly 21, and a plurality of functions for fixing (such as screwing, welding or other methods) on the frame 30 The blade 42, and the functional frame 40 surrounds the periphery of the functional blades 42 with the frame 30 as the center, that is, the functional frame 40 and the frame 30 are concentric ring structures centered on the shaft 24 .

In this embodiment, the functional frame body 40 and the frame body 30 have the same structure, that is, the inner side wall 40a and the outer side wall 40b of the groove structure 400 of the functional frame body 40 face the front and the rear, and the groove The bottom side 30c of the structure 400 surrounds in the up, down, left, and right directions, so that the opening of the groove structure 400 faces the frame 30 (or the shaft 24).

Furthermore, the guide rail assembly 21 is arranged along the annular edge of the functional frame 40, and each functional blade 42 is connected to the driving member 23 so that each functional blade 42 rotates relative to the shaft 24. For example, the frame 30 is pivotally connected to a shaft seat 4b, so that the frame 30 can drive the functional blades 42 to rotate.

In addition, the frame 30 is used as an inner rail, and the functional frame 40 is used as an outer rail, so that the fan 4 is in a multi-track form, and the functional frame 40 and the shaft base 4b are erected on the support base 3a .

In addition, the number of the functional frame 40 can be increased according to requirements to form multiple sets of fans of the fan group 4a.

When using the fan 4, the rotation direction of the functional blades 42 of the fan set 4a may be different from the rotation direction of the blades 22, for example, the functional blades 42 rotate in a clockwise direction, and The blade 22 rotates counterclockwise so that the fan 4 can provide wind power in different directions. It should be understood that the rotation direction of the functional blades 42 of the fan set 4a can be the same as the rotation direction of the blades 22.

5A to 5B are schematic diagrams of the fourth embodiment of the fan 5 of the present invention. The difference between this embodiment and the third embodiment is that another auxiliary frame 50 is added, and the other structure and operation mode are substantially the same. Therefore, only the differences will be described below, and the similarities will not be repeated.

As shown in Figures 5A to 5B, the fan assembly 5a includes a functional frame 40 as a track, the guide rail assembly 21, and a connection (such as integral molding, screw connection, welding, shaft connection or other methods) on the frame The auxiliary frame 50 on the body 30 and a plurality of functional blades 52 provided on the periphery of the auxiliary frame 50, and the auxiliary frame 50 surrounds the periphery of the frame 30 with the frame 30 as the center, that is, the auxiliary frame 50. The functional frame 40 and the frame 30 are concentric ring structures centered on the shaft 24.

In this embodiment, the auxiliary frame 50 and the frame 30 have the same structure, that is, the inner side wall 50a and the outer side wall 50b of the groove structure 500 of the auxiliary frame 50 face the front and the rear, and the groove The bottom side 50c of the structure 500 surrounds in the up, down, left, and right directions, so that the opening of the groove structure 500 faces the functional frame 40.

Furthermore, the guide rail assembly 21 is arranged along the annular edge of the auxiliary frame 50, and the opposite ends of each functional blade 52 are connected to the driving member 23, so that each functional blade 52 rotates relative to the shaft 24 . For example, the auxiliary frame 50 is used as an auxiliary outer rail, and the functional frame 40 is used as a main outer rail, so that the fan 5 is in a multi-track form.

When using the fan 5, the rotation direction of the functional blade 52 of the fan set 5a may be different from the rotation direction of the blade 22, for example, the functional blade 52 rotates in a clockwise direction, and the blade 22 rotates in a counterclockwise direction, In this way, the fan 5 can provide wind power in different directions, and the frame 30 does not need to rotate. It should be understood that the rotation direction of the functional blades 52 of the fan set 5a can be the same as the rotation direction of the blades 22.

Therefore, the fan 5 can be configured on the drone 6 as required. As shown in Figure 5C or 5D, the functional frame 40 and the auxiliary frame 50 are pivotally connected to the frame 30, so that the frame 30 (And the blade 22 in the figure omitted) can rotate relative to the fuselage (or wing 60), or the functional frame 40 and the auxiliary frame 50 (and the functional blade 52 in the figure omitted) relative to the fuselage (or wing 60) Rotate to provide power for the UAV 6 to take off, land and move forward.

On the other hand, there are many types of trench structures 200, 300, 400, and 500, which are not limited to the above. As shown in Fig. 3B', the claw-shaped cross-sectional configuration of the trench structure 300' is not particularly limited.

Therefore, the fans 2, 3, 4, and 5 of the present invention are designed to move the driving member 23 mainly by electromagnetic power. Therefore, compared with the conventional technology, the fans 2, 3, 4, and 5 of the present invention do not need to use conventional motors. In the module, no power mechanism is arranged behind the frames 20, 30, the auxiliary frame 50, and the functional frame 40, so that the volume of the fans 2, 3, 4, and 5 can be reduced.

Furthermore, the fans 2, 3, 4, and 5 of the present invention do not need to use conventional motor modules, and when the blade 22 (and the functional blade 42) rotates, the driving member 23 will not contact the frame 20, 30 ( The auxiliary frame 50 and the functional frame 40) and the guide rail assembly 21 make the fans 2, 3, 4, and 5 hardly generate mechanical noise. Therefore, the fans 2, 3, 4, and 5 of the present invention produce extremely sound low.

In addition, since the supporting seat 3a can be used to support the blade 22 (and the functional blade 42) to support the driving member 23, there is no need to generate magnetic buoyancy for overcoming gravity, so the bottom side 20c, 30c, 40c of the groove structure 200, 300, 400, 500 , There is no need to generate magnetic levitation between 50c and the driving member 23. However, in order to adopt the existing circuit configuration, the magnetic floating force system (ie, the magnetic assembly 34) used in the maglev train can still be used to support the driving member 23, and the manufacturing cost and design cost can be saved.

In addition, the present invention is not limited to the design of household appliances fans 2, 3, 4, 5, and can also be applied to related mechanisms with blades 22, such as computer cooling fans, flying equipment (drone 6) rotors, or underwater equipment (Ships, submarines) and other propellers.

The above-mentioned embodiments are used to exemplify the principles and effects of the present invention, but not to limit the present invention. Anyone familiar with this technique can modify the above-mentioned embodiments without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the rights of the present invention should be the scope of patent application described later.
