Description

Technical Field

[0001] This utility model relates to the field of motor technology, and in particular to a magnetic levitation motor. Background Technology

[0002] A reciprocating magnetic levitation motor is a type of motor that uses the principle of magnetic fields to achieve rotor levitation and reciprocating oscillation. It is widely used in electric personal care devices such as shavers and electric clippers.

[0003] In the prior art, such as the utility model patent with announcement number CN222107757U, a high-performance magnetic levitation swing motor is disclosed. By setting three swing rods, and making the middle swing rod and the two side swing rods move in opposite directions, while the two side swing rods move in the same direction, the resonance and noise generated can be effectively reduced when the motor is running.

[0004] However, as the motor feed tolerance continues to accumulate, the connection of only two linkage components in the above scheme is insufficient to maintain stable coordinated swing of the swing rods on both sides for a long time. This makes the motor prone to problems such as unstable operation and noise after a period of use, so improvements are needed. Utility Model Content

Detailed Implementation

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and accompanying drawings of this invention are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or accompanying drawings of this invention are used to distinguish different objects, not to describe a particular order.

[0021] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0022] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0023] like Figure 1-5 The image shows an embodiment provided by this utility model.

[0024] This utility model embodiment provides a magnetic levitation motor, including: a stator module 10; a first oscillating member 20, a second oscillating member 30, and a third oscillating member 40 arranged side-by-side above the stator module 10; and two sets of first spring plates 50, second spring plates 60, and third spring plates 70 arranged side-by-side on both sides of the stator module 10. Specifically, the lower ends of the two sets of first spring plates 50, second spring plates 60, and third spring plates 70 are respectively connected to the stator module 10, and the upper ends of the two sets of first spring plates 50 are respectively connected to both ends of the first oscillating member 20, supporting the first oscillating member 20 above the stator module 10, and enabling it to oscillate when the first oscillating member 20 oscillates. The first swing member 20 undergoes elastic deformation to buffer and assist in resetting, reducing vibration. The upper ends of the two sets of second spring plates 60 are respectively connected to the two ends of the second swing member 30, supporting the second swing member 30 above the stator module 10. They can also undergo elastic deformation when the second swing member 30 swings, buffering and assisting in resetting, reducing vibration. The upper ends of the two sets of third spring plates 70 are respectively connected to the two ends of the third swing member 40, supporting the third swing member 40 above the stator module 10. They can also undergo elastic deformation when the third swing member 40 swings, buffering and assisting in resetting, reducing vibration.

[0025] The upper ends of the first spring 50 and the third spring 70 are connected by an inverted "U"-shaped connecting part, so that the first swing member 20 and the third swing member 40, which are respectively connected to the first spring 50 and the third spring 70, are connected to form a whole. This can improve the coordination and integration of the first swing member 20 and the third swing member 40, and ensure that the two can move stably and synchronously for a longer period of time. Moreover, the connecting part is higher than the upper end of the second spring 60 and the two ends of the second swing member 30, so that the end of the second swing member 30 can pass normally between the first spring 50 and the second spring 60 without affecting the relative swing of the second swing member 30 with the first swing member 20 and the third swing member 40.

[0026] Furthermore, a linkage 80 connects the second swing member 30 to the first swing member 20 or the third swing member 40. The stator module 10 can drive the first swing member 20 and the third swing member 40 to move back and forth relative to the second swing member 30, and cause the linkage 80 to swing accordingly. The function of the linkage 80 is to limit the swing of the second swing member 30, the first swing member 20, and the third swing member 40, restricting the swing amplitude of the three to a certain range. At the same time, it can ensure that the distance moved by the first swing member 20 and the third swing member 40 is always consistent with the distance moved in the opposite direction by the second swing member 30, thus better maintaining dynamic stability. Balanced, since the first swing member 20 and the third swing member 40 form a whole under the connection of the first spring 50 and the third spring 70, the linkage member 80 only needs to be connected to the second swing member 30 at one end. The other end can be connected to the first swing member 20 or the third swing member 40 to achieve the same effect. Compared with the original requirement to set linkage members 80 between the first swing member 20 and the second swing member 30 and between the second swing member 30 and the third swing member 40, the assembly of the connection points is simpler, and one linkage member 80 can be reduced, thus reducing the cost of parts and assembly.

[0027] After adopting the above-mentioned magnetic levitation motor, the first swing member 20 and the third swing member 40 are connected into a whole by the first spring plate 50 and the third spring plate 70 with the upper end connected in an inverted "U" shape. The second swing member 30 is linked with the first swing member 20 or the third swing member 40 by a linkage component 80. Compared with the existing three separate swing rods and two linkage components 80, the first swing member 20 and the third swing member 40 have a higher degree of integrity, which helps to maintain a more stable coordinated motion and enables the motor to run stably for a longer period of time.

[0028] In one embodiment, please refer to the appendix. Figure 4 As shown, the upper ends of the first spring 50 and the third spring 70 are integrally connected, which can improve the connection strength of the first spring 50 and the second spring 60, and make the first swing member 20 and the third swing member 40 more integrated.

[0029] In another embodiment, referring to the attached Figure 5 , an inverted U-shaped fixing piece 51 is detachably connected to the upper ends of the first elastic sheet 50 and the third elastic sheet 70, which facilitates disassembly and assembly.

[0030] Specifically, the first swinging member 20, the second swinging member 30, and the third swinging member 40 are all made of zinc alloy. Compared with the commonly used plastic material in the prior art, zinc alloy has higher mass and strength, which can improve the motion inertia of the three swinging members and prolong the service life of the three swinging members.

[0031] Specifically, the bottoms of the first swinging member 20, the second swinging member 30, and the third swinging member 40 are respectively provided with a first mover 21, a second mover 31, and a third mover 41. The first mover 21, the second mover 31, and the third mover 41 are arranged parallel and side by side above the stator module 10 and are inductively connected with the stator module 10. The stator module 10 can drive the first mover 21 and the third mover 41 to reciprocate together in the opposite direction of the second mover 31, thereby driving the first swinging member 20 and the third swinging member 40 to reciprocate together in the opposite direction of the second swinging member 30. When the second mover 31 moves forward, the first mover 21 and the third mover 41 move backward together; on the contrary, when the second mover 31 moves backward, the first mover 21 and the third mover 41 move forward together.

[0032] Further, the first swinging member 20, the second swinging member 30, and the third swinging member 40 have the same structure, all of which are substantially mountain-shaped. One end of the linkage member 80 is connected to the top or one side shoulder of the second swinging member 30, and the other end of the linkage member 80 is correspondingly connected to the same position on the first swinging member 20 or the third swinging member 40, so that the linkage member 80 maintains a horizontal swinging state.

[0033] Further, two ends of the linkage member 80 are respectively provided with strip-shaped connecting holes 81. A first limiting shaft 22 is provided on the first swinging member 20 or the third swinging member 40, and a second limiting shaft 32 is vertically provided on the second swinging member 30. The two connecting holes 81 are respectively rotatably connected with the first limiting shaft 22 and the second limiting shaft 32, and the swing center of the linkage member 80 is located on the symmetry center of the second swinging member 30 and the first swinging member 20 or the third swinging member 40.

[0034] Specifically, a fixing frame 11 is provided outside the stator module 10. A clearance opening 12 is provided on the top of the fixing frame 11. The upper ends of the first swing member 20, the second swing member 30, and the third swing member 40 extend out of the clearance opening 12 side by side and can move back and forth within the clearance opening 12. Spring fixing seats 13 are provided on both sides of the clearance opening 12. At least two sets of return springs 14 are connected to the inner side of each spring fixing seat 13. The front and rear ends of the first swing member 20, the second swing member 30, and the third swing member 40 can be connected to the outer ends of the return springs 14. When the first swing member 20, the second swing member 30, and the third swing member 40 swing back and forth alternately, the return springs 14 on both sides can buffer and assist in the reset of the movement of the first swing member 20, the second swing member 30, and the third swing member 40, which can reduce vibration and further improve the stability of the motor operation.

[0035] Obviously, the embodiments described above are only some embodiments of this utility model, not all embodiments. The accompanying drawings show preferred embodiments of this utility model, but do not limit the patent scope of this utility model. This utility model can be implemented in many different forms; rather, the purpose of providing these embodiments is to provide a more thorough and comprehensive understanding of the disclosure of this utility model. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing specific embodiments, or make equivalent substitutions for some of the technical features. Any equivalent structures made using the content of this utility model specification and drawings, directly or indirectly applied to other related technical fields, are similarly within the patent protection scope of this utility model.
