[0009] Wherein, the two arc-shaped electromagnets drive the positioning shaft to rotate clockwise under the action of a first current direction, and the two arc-shaped electromagnets drive the positioning shaft to rotate counterclockwise under the action of a second current direction.

[0010] In some examples of the present utility model, the arc-shaped electromagnets are respectively a first arc-shaped electromagnet and a second arc-shaped electromagnet. The two ends of the first arc-shaped electromagnet are respectively a first end and a second end, and the two ends of the second arc-shaped electromagnet are respectively a third end and a fourth end. The second end and the fourth end are respectively located on both sides of the first permanent magnet, and the magnetic pole directions of the second end and the fourth end are opposite.

[0011] In some examples of the present utility model, the magnetic pole direction of the first permanent magnet near the second end is the S pole. Under the action of the first current direction, the magnetic pole directions of the second end and the fourth end are the N pole, and the magnetic pole directions of the first end and the third end are the S pole. The magnetic pole direction of the first permanent magnet, the magnetic pole direction of the first arc-shaped electromagnet, and the magnetic pole direction of the second arc-shaped electromagnet are adapted so that the positioning shaft rotates clockwise under the first current direction.

[0012] In some examples of the present utility model, the magnetic pole direction of the first permanent magnet near the second end is the N pole.

When the direction of the first current is switched to the second current direction, the arc-shaped electromagnet generates magnetic force with the first permanent magnet and the second permanent magnet on the positioning shaft.

And when the positioning shaft is in any one of the first position or the second position, one end of the two arc-shaped electromagnets generates suction force on the positioning shaft, and the other end of the two arc-shaped electromagnets generates repulsive force on the positioning shaft, causing it to deflect. When the current direction changes, the suction force and the repulsive force are interchanged, thereby driving the positioning shaft to rotate. Under the combined action of the two arc-shaped electromagnets and the fixed position, the rotation of the positioning shaft can be made more stable. Description of the Drawings

The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation of the present utility model.

[0035] Reference is made below to Figures 1-3 Describe a switching mechanism of a waveguide switch 100 provided according to an embodiment of the present utility model, including the waveguide switch 100, further including:

[0036] A positioning disk 200, the positioning disk 200 is fixedly connected to the stator 110 of the waveguide switch 100, and the rotor 120 of the waveguide switch 100 extends out of the center of the positioning disk 200. The positioning disk 200 is generally made of a hard material. The positioning plate and the stator 110 of the waveguide switch 100 are generally fixedly connected by means such as welding and clamping. A through hole is provided in the center of the positioning plate so that the rotor 120 of the waveguide switch 100 can extend out of the positioning disk 200;

[0037] A positioning shaft 300, the positioning shaft 300 is fixedly connected to the rotor 120. Generally, the positioning shaft 300 and the rotor 120 are fixedly connected by means such as welding and threaded connection. First permanent magnets 310 and second permanent magnets 320 are respectively provided at both ends of the positioning shaft 300. The first permanent magnets 310 and the second permanent magnets 320 are any one of neodymium iron boron permanent magnets, cobalt cobalt iron permanent magnets, ferrite permanent magnets, and cobalt aluminum oxides. Among them, neodymium iron boron permanent magnets are one of the fastest developing and best performing permanent magnet materials at present, having characteristics such as high energy density, excellent magnetic properties, and mechanical properties. And cobalt cobalt iron permanent magnets: are cobalt-based permanent magnet materials, having high saturation magnetization intensity and magnetic crystal anisotropy, and are suitable for making micro-devices, high-frequency switches, magnetic sensors and other fields; Ferrite permanent magnets are a kind of hard magnetic material, having characteristics such as good heat resistance, corrosion resistance, stability, reliability, and easy manipulation, and are used in inductance elements, magnetic beads, energy storage devices, RFID, medical devices, and radar and other fields; Cobalt aluminum oxide is a new type of permanent magnet material, having unique properties such as double-paramagnetic hard magnetic properties, high magnetic anisotropy, scale effect, and spin-charge transfer, and has been widely studied and applied in magnetic energy storage, spintronic devices and other fields. And the magnetic pole directions of the first permanent magnets 310 and the second permanent magnets 320 are both perpendicular to the axis direction of the positioning shaft 300. If the axis direction of the positioning shaft 300 is the longitudinal direction, then the magnetic pole directions of the first permanent magnets 310 and the second permanent magnets are the transverse direction, and the magnetic pole directions of the first permanent magnets 310 and the second permanent magnets 320 are the same;

[0038] Two arc-shaped electromagnets are symmetrically installed on the positioning disk 200. The curvatures of the two arc-shaped electromagnets are equal, so that the two symmetrically installed arc-shaped electromagnets can be on the same circumferential surface, where this circumferential surface is the circumferential surface on which the first permanent magnet 310 and the second permanent magnet 320 rotate. Thus, during the rotation of the positioning shaft 300, the arc-shaped electromagnets can abut against the first permanent magnet 310 and the second permanent magnet 320. A support is provided at the bottom of the arc-shaped electromagnet, and the arc-shaped electromagnet is snap-fitted onto the positioning disk 200 through the support. The arc-shaped electromagnet installed by the above method is more firmly installed, can withstand the heavy impact during the rotation of the positioning shaft 300, and is more durable in use;

[0039] Among them, the two arc-shaped electromagnets drive the positioning shaft 300 to rotate clockwise under the action of the first current direction, and the two arc-shaped electromagnets drive the positioning shaft 300 to rotate counterclockwise under the action of the second current direction. When the current direction is changed from the first current direction to the second current direction, specifically, the magnetic poles of the two arc-shaped electromagnets located on both sides of the same permanent magnet are opposite, so that the two arc-shaped electromagnets can respectively generate attractive and repulsive forces on the permanent magnet, causing it to rotate in the same direction.

[0040] Through the above structure, under the action of the first current direction, the arc-shaped electromagnet generates magnetic force with the first permanent magnet 310 and the second permanent magnet 320 on the positioning shaft 300, thereby driving the positioning shaft 300 to rotate clockwise until it rotates to the second position. When the direction of the first current is switched to the second current direction, the arc-shaped electromagnet generates a reverse magnetic force. Since the current direction is opposite, the generated magnetic force direction is opposite, so that the positioning shaft 300 rotates counterclockwise and rotates from the second position to the first position, thus realizing the switching function of the waveguide switch 100. And when the positioning shaft 300 is at any one of the first position or the second position, one end of the two arc-shaped electromagnets generates an attractive force on the positioning shaft 300, and the other end of the two arc-shaped electromagnets generates a repulsive force on the positioning shaft 300, causing it to deflect. When the current direction changes, the attractive force and the repulsive force are interchanged, thereby driving the positioning shaft 300 to rotate. Under the combined action of the two arc-shaped electromagnets and the fixed position, the rotation of the positioning shaft 300 can be made more stable.

[0041] Please continue to participate Figures 1-3As shown, the arc-shaped electromagnets are respectively a first arc-shaped electromagnet 400 and a second arc-shaped electromagnet 410. The two ends of the first arc-shaped electromagnet 400 are respectively a first end 420 and a second end 430. The two ends of the second arc-shaped electromagnet 410 are respectively a third end 440 and a fourth end 450. The second end 430 and the fourth end 450 are respectively located on both sides of the first permanent magnet 310, and the magnetic pole directions of the second end 430 and the fourth end 450 are opposite.

[0042] Specifically, the magnetic pole directions of the second end 430 and the fourth end 450 are opposite. At the same time, the first end 420 and the second end 430 are respectively the two ends of the first arc-shaped electromagnet 400, and the third end 440 and the fourth end 450 are respectively the two ends of the second arc-shaped electromagnet 410. Therefore, the magnetic pole of the first end 420 is the same as that of the fourth end 450, and the magnetic pole of the second end 430 is the same as that of the third end 440. When the first arc-shaped electromagnet 400 and the second arc-shaped electromagnet 410 are connected in the first current direction, the magnetic poles of the two arc-shaped electromagnets located on both sides of the same permanent magnet are opposite, so that the two arc-shaped electromagnets can respectively generate attractive and repulsive forces on the permanent magnet, causing the permanent magnet to rotate in the same direction.

[0043] Please refer to Figure 2 、 Figure 4 As shown, according to a switching mechanism of a waveguide switch 100 provided by an embodiment of the present invention, the magnetic pole direction of the first permanent magnet 310 close to the second end 430 is the S pole. Under the action of the first current direction, the magnetic pole directions of the second end 430 and the fourth end 450 are the N pole, and the magnetic pole directions of the first end 420 and the third end 440 are the S pole. The magnetic pole directions of the first permanent magnet 310, the first arc-shaped electromagnet 400, and the second arc-shaped electromagnet 410 are adapted so that the positioning shaft 300 rotates clockwise in the first current direction.

[0044] Specifically, the N pole of the first permanent magnet 310 is close to the second end 430, thus generating the principle of attracting each other with opposite sex. The second end 430 attracts the first permanent magnet 310 to rotate clockwise. At the same time, the S pole of the first permanent magnet 310 repels the fourth end 450 to generate a repulsive force, causing the first permanent magnet 310 to rotate clockwise. Similarly, the first end 420 and the third end 440 generate a force that causes the second permanent magnet 320 to rotate clockwise on the second permanent magnet 320, thereby driving the positioning shaft 300 to rotate.

[0045] Please continue to refer to Figure 2 、 Figure 5As shown, according to an embodiment of the present utility model, the magnetic pole direction of the first permanent magnet 310 close to the second end 430 is the N pole. Under the action of the first current direction, the magnetic pole directions of the second end 430 and the fourth end 450 are the S pole, the magnetic pole directions of the first end 420 and the third end 440 are the N pole, the magnetic pole direction of the first permanent magnet 310 close to the second end 430 is the N pole, and the side of the second permanent magnet 320 close to the first end 420 is the S pole.

[0046] Specifically, the N pole of the first permanent magnet 310 is close to the second end 430. According to the principle of attraction between opposite poles, the second end 430 attracts the first permanent magnet 310 to rotate clockwise. At the same time, the S pole of the first permanent magnet 310 repels the fourth end 450 to generate a repulsive force, causing the first permanent magnet 310 to rotate clockwise. Similarly, the first end 420 and the third end 440 generate a force that causes the second permanent magnet 320 to rotate clockwise, thereby driving the positioning shaft 300 to rotate.

[0047] Please continue to refer to Figure 3 As shown, according to another embodiment of the present utility model, a jack 500 is provided at the center of the positioning shaft 300. The jack 500 is adapted to the rotor 120 so that the jack 500 can be inserted onto the rotor 120. The shape of the rotor 120 is adapted to the shape of the jack 500. For example, when the cross-sectional shape of the rotor 120 is circular, the cross-sectional shape of the jack 500 is circular; when the cross-sectional shape of the rotor 120 is rectangular, the cross-sectional shape of the jack 500 is rectangular.

[0048] Specifically, processes such as drilling method, milling method, laser cutting method, water jet cutting method, etc. can be selected to make the jack 500 on the positioning shaft 300. Among them, the drilling method is mainly applicable to the opening of materials such as metals, woods, and walls. By rotating and moving up and down the drill bit, a circular hole of the required size is drilled. The boring method is mainly applicable to workpieces with high machining accuracy requirements and large hole diameters. By driving the boring tool to rotate and move axially along the workpiece by the tool rest or manipulator, cutting processing is carried out; the milling method is mainly applicable to the processing of materials such as metals, plastics, and woods with complex types and high surface process requirements. By rotating and cutting the milling cutter, holes of the required shape are processed on the workpiece; laser cutting method: mainly applicable to the processing of materials such as metals, plastics, and non-crystals. By focusing the high-energy laser beam on the workpiece surface, the workpiece is cut and melted; water jet cutting method: mainly applicable to high-quality materials of various hardnesses and thicknesses. By high-pressure water flow and abrasives of different qualities, cutting and processing are carried out on the workpiece.

[0049] Please continue to refer to Figure 3As shown, according to another embodiment of the present utility model, a clamping block 510 is provided at the end of the rotor 120. The clamping block 510 is used to prevent the positioning shaft 300 from sliding relative to the rotor 120. By providing the clamping block 510 on the rotor 120, it is possible to avoid slippage between the positioning shaft 300 and the rotor 120 during use, thereby increasing the service life of the device.

[0050] Specifically, the shape of the clamping block 510 is generally a rectangular block. The clamping block 510 is welded to the end of the rotor 120 by processes such as welding. Usually, two clamping blocks 510 are provided in the circumferential direction at the end of the rotor 120, so that the contact area between the clamping block 510 and the rotor 120 is larger and the installation is more stable.

[0051] Please continue to refer to Figure 3 As shown, according to an alternative embodiment of the present utility model, the positioning shaft 300 is a hollow member. The central position of the positioning shaft 300 is a solid structure, while the middle position of the positioning shaft 300 extends in both end directions as a hollow structure. The use of a hollow structure can reduce the self-weight of the positioning shaft 300 and reduce the energy required to drive the positioning shaft 300. Installation holes are provided at the ends of the positioning shaft 300, and the first permanent magnet 310 and the second permanent magnet 320 are snapped into and installed at both ends of the positioning shaft 300.

[0052] Specifically, the above structure can be achieved by welding two hollow pipe fittings to both ends of the solid pipe fitting, and it can also be achieved by casting, which can be realized according to different conditions.

[0053] According to a further embodiment of the present utility model, the positioning disk 200 is fixedly connected to the stator 110 of the waveguide switch 100 through positioning pins and screws. A plurality of first mounting holes are provided in the positioning disk 200. Usually, four second mounting holes can be provided on the outer edge of the stator 110. The positioning pins and the screws pass through the first mounting holes and the second mounting holes to achieve the...
