Description

Technical Field

[0001] This utility model relates to the field of magnetic levitation motor technology for shavers, specifically to a magnetic levitation motor with an ultra-long lifespan. Background Technology

[0002] In the traditional hair clipper and shaver industry, the magnetic levitation motors currently used have two-moving-column and three-moving-column configurations. For example, in CN222107757U, the first and second linkage components are used to connect and follow the deflection of the swing arm. Another example is CN221240237U, where a linkage limit component is set between the first and second swing arms. The main purpose of the linkage components in the linkage methods of the above two patents is to connect the moving parts to each other so that all the moving part torques are transferred to the main output shaft to provide the load with the maximum efficiency torque output and to reset the output shaft or all moving parts.

[0003] However, this method has two major drawbacks: 1) All the guide holes of the linkage are subject to high-speed friction with the mating shaft. Over time, this friction causes the guide holes to wear and generate noise; 2) Existing methods to improve noise primarily involve controlling the tolerance of the guide holes for interference fit and using more wear-resistant materials to eliminate noise between the guide holes and the shaft. However, interference fit sacrifices a larger load current. The greater the interference, the greater the operating current, the more severe the heat generation, and the shorter the runtime. Using more wear-resistant materials cannot completely solve the wear problem caused by over time; 3) It cannot achieve truly high speeds because higher speeds result in greater wear on the linkage and a shorter motor lifespan. High-speed friction eventually creates a gap between the guide holes and the shaft, leading to earlier and greater noise. Therefore, an ultra-long-life magnetic levitation motor is proposed to solve these problems. Utility Model Content

[0008] The second set of springs is elastically connected between the output swing rod and a fixed reference component; the fixed reference component is fixedly mounted on the motor's support structure.

[0009] As a preferred embodiment of this utility model, the driven swing rod includes a first driven swing rod and a second driven swing rod. The first driven swing rod and the second driven swing rod are both snapped and fixed on the first linkage cover plate, and the output swing rod is snapped and fixed on the second linkage cover plate.

[0029] The core of the magnetic levitation motor described in this utility model lies in the innovative layout of its return spring system. (See also...) Figures 1 to 4 The core concept of this system is to provide a dual-reference reset spring assembly for the moving part module. The moving part module includes at least one output swing rod 16 as a power output and at least one driven swing rod 17 that works in conjunction with the output swing rod 16. The reset spring assembly includes a first set of springs 14 and a second set of springs 15. The first set of springs 14 is elastically connected between the output swing rod 16 and the driven swing rod 17, used to achieve force coupling and basic reset within the moving part assembly. The second set of springs 15 is elastically connected between the output swing rod 16 and a fixed reference component 5, which is fixedly mounted on the motor's support structure (such as the gantry frame 4), thereby establishing an independent, stable, and wear-free direct reset reference for the output swing rod 16.

[0030] The present invention will now be described in detail using a preferred embodiment comprising one output swing rod and two driven swing rods as an example. Those skilled in the art will understand that this is not a limitation of the present invention. For example, the mover module may have only one driven swing rod, or more than two driven swing rods, as long as it employs the aforementioned double-spring reset principle, it falls within the protection scope of the present invention.

[0031] The technical solution of this utility model will now be clearly and completely described in conjunction with the accompanying drawings. In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0032] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] The present invention will be further described below with reference to the accompanying drawings.

[0034] Please refer to the following: Figures 1-9 This utility model discloses an ultra-long lifespan magnetic levitation motor, comprising:

[0035] Stator module;

[0036] The moving module includes a swingable output swing rod 16 and at least one driven swing rod 17;

[0037] The reset spring assembly includes a first set of springs 14 and a second set of springs 15. The first set of springs 14 is elastically connected between the output swing rod 16 and the driven swing rod 17.

[0038] The second set of springs 15 is elastically connected between the output swing rod 16 and a fixed reference member 5; the fixed reference member 5 is fixedly installed on the motor support structure.

[0039] The moving module includes an output swing rod 16, a first driven swing rod 171 and a second driven swing rod 172. The first driven swing rod 171 and the second driven swing rod 172 are both snapped together and fixed to the first linkage cover plate 12 with screws. The output swing rod 16 is snapped together and fixed to the second linkage cover plate 13 with screws.

[0040] The reset spring assembly includes a first set of springs 14 and a second set of springs 15. The first set of springs 14 is symmetrically abutted and locked on both sides of the lower end of the output swing rod 16, and the end away from the output swing rod 16 abuts against the first linkage cover plate 12. The second set of springs 15 is symmetrically abutted and locked on both sides of the upper end of the output swing rod 16, and the end away from the output swing rod 16 abuts against the fixed reference member 5.

[0041] The fixed reference component 5 is fixedly connected to the top of the gantry frame 4 with screws. The first linkage cover plate 12 is symmetrically riveted to both ends of the first driven swing rod 171. The first linkage cover plate 12 is symmetrically riveted to both ends of the second driven swing rod 172. The second linkage cover plate 13 is symmetrically riveted to both ends of the output swing rod 16. The bottoms of the third spring 11, the first spring 9, and the second spring 10 are all fixedly connected between the clamping plates 8. The first spring 9 and the second spring 10 are of the same size. The first driven swing rod 171 and the second driven swing rod 172 are of the same size. The first set of springs 14 and the second set of springs 15 each have two springs. The two springs in the first set of springs 14 are of the same size, and the two springs in the second set of springs 15 are of the same size. This ensures that the spring elasticity on both sides is the same.

[0042] The stator module includes a stator body 1, a coil frame 2, and a base 3. The coil frame 2 is fitted into the middle of the upper part of the stator body 1, and the base 3 is snapped into the bottom of the stator body 1. The stator body 1 and the base 3 are fixedly connected to the gantry frame 4 by bolts. The base 3 is fixedly connected to the clamping pieces 8 by screws on both sides. The fixed reference piece 5 and the first linkage cover plate 12 are both pre-cut with hollowed-out openings. The upper end of the output swing rod 16 passes through the hollowed-out opening on the fixed reference piece 5. The bottom of the output swing rod 16, the first driven swing rod 171, and the second driven swing rod 172 are all provided with moving parts 18. The moving parts 18 are directly opposite the top of the stator body 1. The top of the output swing rod 16 is connected to a drive rod 19. The drive rod 19 is located on the top of the fixed reference piece 5. The drive rod 19 can be connected to and drive the cutter head.

[0043] Specifically, when this invention is used, the addition of the first set of springs 14 and the second set of springs 15 deforms the "resonance" state, aligning the motor's operating frequency with the system's inherent mechanical frequency, thereby obtaining the maximum amplitude (displacement) and force with minimal energy input. The first set of springs 14 is installed between the intermediate output swing rod 16 and the first linkage cover plate 12. The second set of springs 15 is symmetrically abutted and snapped onto both sides of the upper end of the output swing rod 16, with the end away from the output swing rod 16 abutting against the fixed reference member 5. Under magnetic force, the moving body 18 will generate a "resonance" state, efficiently converting energy between kinetic and potential energy. After the system starts working: when the moving body 18 moves to the right, it compresses the right-side spring, converting kinetic energy into the elastic potential energy of the spring and storing it. When the moving body reaches the right end and begins to return, the compressed spring releases its elastic potential energy, helping the motor push the moving body back to the center. Similarly, when moving to the left, the left-side spring also stores and releases energy.

[0044] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0045] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
