[0046] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0047] As attached Figure 1-5 As shown, an embodiment of the present invention provides a magnetic levitation swing motor, which includes: a stator assembly 1, a mover assembly 2 and a linkage plate 3; the mover assembly 2 is movably arranged above the stator assembly 1; the mover assembly 2 includes a first connecting rod 21, a second connecting rod 22 and a third connecting rod 23 that can undergo relative displacement, the moving direction of the first connecting rod 21 is always opposite to that of the second connecting rod 22 and the third connecting rod 23, and the moving directions of the second connecting rod 22 and the third connecting rod 23 are consistent; the linkage plate 3 is fixedly connected to the second connecting rod 22 and the third connecting rod 23, and a guide hole 30 is provided on the linkage plate 3 for repeated movement of the first connecting rod 21.

[0048] Specifically, the mover assembly 2 is capable of performing high-frequency reciprocating motion under the drive of the stator assembly 1, which is a well-known technology in the field and will not be repeated in this embodiment; in this embodiment, the first connecting rod 21 is between the second connecting rod 22 and the third connecting rod 23, and the moving directions of the second connecting rod 22 and the third connecting rod 23 are opposite to the moving directions of the first connecting rod 21, wherein the second connecting rod 22 and the third connecting rod 23 are connected by the linkage plate 3, so that the two can perform the same reciprocating motion more stably, and in order to avoid interfering with the reciprocating motion of the first connecting rod 21, a guide hole 30 is provided in the central position of the linkage plate 3, and the second connecting rod 22 and the third connecting rod 23 are set to move in the opposite direction of the first connecting rod 21, which can balance the amplitude and reduce the vibration generated during high-frequency reciprocating motion, thereby reducing noise, and the setting of the linkage plate 3 can make The same-direction deflection of the second link 22 and the third link 23 is more stable, and the movement of each link is more reliable; in addition, the stator assembly 1 is equipped with a plurality of movers 20 at the bottom of the first link 21, the second link 22, and the third link 23, and the top of the first link 21 is fixedly connected with a driving rod 210, and the tops of the second link 22 and the third link 23 are provided with auxiliary rods 230, wherein, connecting notches 31 are opened on both sides of the linkage plate 3, and the connecting notches 31 are connected to the movers 20 at the bottom of the second link 22 and the third link 23, so that the second link 22 and the third link 23 can maintain a stable same-direction deflection, and the driving rod 210 of the first link 21 is used to output power to the outside. For example, when the magnetic levitation swing motor is used on a hair clipper, the driving rod 210 can drive the cutter head of the hair clipper to move back and forth at high speed.

[0049] In order to provide thrust to the first link 21 to reset the first link 21 when the second link 22 and the third link 23 move in the same direction, the magnetic levitation swing motor also includes a reset assembly 7, which includes two reset springs 70; the linkage plate 3 is provided with two baffles 32 extending upward, and the inner side of the baffle 32 is provided with a protrusion for installing the reset spring 70, and the baffle 32 is connected to the first link 21 through the reset spring 70; specifically, the protrusion is fixed to the baffle 32 by screws, and the baffle 32 and the first link 21 are connected by the reset spring 70, that is, the movement of the first link 21 is related to the movement of the second link 22 and the third link 23, so that the second link 22 and the third link 23 can provide a force for the first link 21 when they move in the same direction.

When the first connecting rod 21, the second connecting rod 22 and the third connecting rod 23 move and yaw, the corresponding elastic sheets 42 will generate corresponding deformation and bending, and the elastic sheets 42 can provide auxiliary thrust for the reset of the corresponding connecting rods, and at the same time improve the structural stability of the first connecting rod 21, the second connecting rod 22 and the third connecting rod 23 corresponding to the mover 20.

[0053] Refer to the appendix Figure 5The magnetic levitation swing motor also includes a support assembly 5, which serves as a carrier for the stator assembly 1 and the mover assembly 2; the support assembly 5 includes a connecting frame 50, which has four legs 500 extending downward, and the legs 500 are used to connect the stator assembly 1; three reserved holes 501 are provided on the top of the connecting frame 50, and the three reserved holes 501 correspond to the first connecting rod 21, the second connecting rod 22 and the third connecting rod 23 respectively. Specifically, the legs 500 of the connecting frame 50 are fixedly connected to the carrier 10 of the stator assembly 1, and a plurality of external connection holes 502 are provided on the connecting frame 50, which facilitates the assembly of the magnetic levitation swing motor into the corresponding equipment, such as assembling it into the inside of a hair clipper to provide power for its cutting head; in addition, the reserved holes 501 are all bar-shaped holes extending along the swing direction of the connecting rod, so as to avoid interference of the connecting rod with the connecting frame 50 during reciprocating motion.

[0054] In order to further increase the output torque of the driving rod 210 of the first connecting rod 21, the magnetic levitation swing motor further includes a deflection member 60 and a pressure plate 61. The pressure plate 61 is generally convex in shape, with both ends of the pressure plate 61 fixedly connected to the top of the connecting frame 50. The deflection member 60 is rotatably connected to the pressure plate 61 and is positioned between the pressure plate 61 and the connecting frame 50. The two ends of the deflection member 60 are respectively movably connected to the driving rod 210 and any one of the auxiliary rods 230. Specifically, both ends of the deflection member 60 are provided with waist-shaped holes 600, through which the driving rod 210 and any one of the auxiliary rods 230 pass respectively. For example, by connecting the deflection member 60 to the driving rod 210 and the auxiliary rod 230 of the second connecting rod 22, the swing of the auxiliary rod 230 can drive the follow-up swing of the driving rod 210 in the opposite direction through the deflection member 60, further providing power to the driving rod 210 and increasing the output torque of the driving rod 210.
