Description

Technical Field

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

[0002] A magnetic levitation oscillating motor is a type of motor structure that uses the principle of magnetic induction to achieve power output. It is also commonly referred to as a magnetic levitation motor, magnetic induction oscillating motor, or magnetic levitation vibration motor.

[0003] In the prior art, for example, Chinese invention patent application CN114123702A discloses a brushless electromagnetic levitation vibration motor, the structure of which includes:

[0004] The bottom corner support has a coil fixing base that is snapped into place on top. The stator coil and stator are fixedly installed inside the coil fixing base. The stator coil is wound around the outside of the stator. The top of the stator protrudes outward from the top of the coil fixing base. There are spring pieces on both sides of the bottom corner support. The coil fixing base and the spring pieces are connected to a magnetic induction interleaved opposing moving module.

[0005] The magnetic induction interleaved opposing movement module includes a swing rod fixed between two springs. The bottom end of each swing rod is fixedly connected to a mover. The top ends of the two springs are connected to a spring connecting seat. The top ends of the spring connecting seat are rotatably connected to two sets of connecting rods. The inside of the spring connecting seat is provided with a through groove. The swing rod is set inside the through groove. The bottom end of the swing rod is located below the spring connecting seat.

[0006] The bottom corner support and the coil fixing base are fixedly engaged together by slots and edge protrusions, respectively. The slots are symmetrically opened on both sides of the bottom of the coil fixing base, and the edge protrusions are fixedly connected to both sides of the top of the bottom corner support. The slots and edge protrusions are compatible with each other.

[0007] The front and back sides of the coil fixing base are respectively fixedly connected to the front support frame and the rear support frame. The front support frame, the rear support frame and the bottom corner support are all connected by frame connectors.

[0008] The positions of the moving parts correspond to those of the stators, but they do not contact each other; the swing rod has a "T" shaped structure.

[0009] A limiting seat is fixedly connected between the tops of the front support frame and the rear support frame, and a swing limiting groove is provided inside the limiting seat;

[0010] The top of the swing arm extends above the limit seat and is fixedly connected to a drive rod, which is located above the limit seat.

[0011] Spring limiting protrusions B are fixedly installed on the inner side of the top of the front support frame and the rear support frame. Spring limiting protrusions A are fixedly installed on both sides of the top of the swing rod. A return spring is provided between the spring limiting protrusions A and the spring limiting protrusions B.

[0012] The aforementioned brushless electromagnetic levitation vibration motor, through the principle of magnetic induction, introduces alternating currents into the magnetic coil. Under the action of the stator, it causes two moving parts to move back and forth in an alternating manner. When the moving parts move, the parts above the moving parts move along with them, thereby causing the spring to deform and oscillate back and forth. During the movement of the structure above the moving parts, it simultaneously applies a force to the spring and the return spring on the same side. On the one hand, it plays a buffering role. On the other hand, when the applied force reaches a critical value, the spring and the return spring will simultaneously apply a reaction force, i.e., a rebound force. This enables the motor to perform high-speed reciprocating motion. Furthermore, the connecting rod itself oscillates along with the moving parts when the spring connecting seats move towards each other, increasing the torque.

[0013] However, the aforementioned brushless electromagnetic levitation vibration motor has the drawback of requiring a large number of parts, which makes the overall structure more complex. This not only leads to higher manufacturing costs but also makes assembly more cumbersome and inconvenient, affecting assembly efficiency.

[0014] Therefore, it is necessary to optimize and improve existing technologies. Utility Model Content

[0015] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a magnetic levitation swing motor with a simple and reasonable structure, which helps to reduce manufacturing costs and assembly difficulty.

[0016] To achieve the above objectives, the present invention adopts the following technical solution.

[0017] The present invention provides a magnetic levitation swing motor, including a stator coil assembly, a mover, a spring, a swing frame and a return spring. The mover is correspondingly engaged with the stator coil assembly, and the spring is provided on both sides of the stator coil assembly.

[0018] It also includes an integral support frame, which forms an accommodating space for accommodating the stator coil assembly and the swing frame.

[0024] Further, the stator is in a "mountain" shape. The middle part of the stator has a central column. The stator coil is wound around the outside of the central column, and the top end of the central column protrudes from the upper end surface of the stator coil.

[0025] Further, two swing frames are provided above the stator coil assembly. The two swing frames are arranged side by side in the horizontal direction. The tops of the bosses of the two swing frames are jointly connected with a limiting connecting rod. Swing limiting grooves are respectively provided at both ends of the limiting connecting rod.

The support frame further includes a mounting seat provided on the top of the frame body. The mounting seat is provided with a mounting shaft, and the middle part of the limiting connecting rod is rotatably connected to the mounting shaft.

[0026] Further, an output shaft is provided on the boss of one of the swing frames, and the output shaft also serves as the limiting pin shaft provided on the corresponding boss.

[0028] Further, a spring seat that abuts and cooperates with the reset spring is provided on the inner side of the connection seat.

[0030] The beneficial effects of this utility model are as follows: Compared with the prior art, the magnetic levitation swing motor provided by this utility model optimizes and improves the structure of the motor. For example, it uses an integrated support frame to replace the separate bottom corner support, front support frame, rear support rod frame and limit seat in the prior art. It also eliminates the spring contact seat in the prior art, which effectively reduces the number of parts required for the whole machine, making the whole machine structure simple and reasonable. This not only effectively reduces the production and manufacturing cost, but also helps to reduce the assembly difficulty, thereby improving the assembly efficiency. Attached Figure Description

[0037] The present invention will be further described below with reference to the accompanying drawings.

[0038] like Figures 1 to 4 The magnetic levitation swing motor shown includes a support frame 1, a stator coil assembly 2, a mover 3, a spring 4, a swing frame 5, and a return spring 6. The mover 3 is correspondingly engaged with the stator coil assembly 2. The stator coil assembly 2 has springs 4 on both sides. The stator coil assembly 2 includes a stator 21 and a stator coil 22. The stator coil 22 is wound around the outside of the stator 21. The stator 21 is shaped like a "mountain". The middle part of the stator 21 has a central column 211. The stator coil 22 is wound around the outside of the central column 211. The top of the central column 211 protrudes from the upper end face of the stator coil 22. The mover 3 is a permanent magnet.

[0039] like Figure 4 As shown in the figure, the support frame 1 is integrally arranged. For the convenience of installation, the support frame 1 is generally arranged in a semi-enclosed shape like a "C", and the support frame 1 forms an accommodation space 14 for accommodating the stator coil assembly 2 and the swing frame 5. The support frame 1 includes a frame body 11, a base 12 arranged at the bottom of the frame body 11, and connecting seats 13 arranged on both sides of the top of the frame body 11; the stator coil assembly 2 is fixedly connected to the base 12. In this embodiment, the stator 21 is fixedly connected to the base 12, the bottom end of the elastic piece 4 is fixedly connected to the base 12, and the top end of the elastic piece 4 is fixedly connected to the swing frame 5, so that the swing frame 5 is suspended above the stator coil assembly 2 movably, and the mover 3 is fixedly arranged at the bottom of the swing frame 5; a boss 51 is arranged at the upper end of the swing frame 5. In this embodiment, the boss 51 is located at the center of the swing frame 5, and a return spring 6 is arranged on both sides of the boss 51, and the return spring 6 abuts between the boss 51 and the connecting seat 13.

[0040] For the magnetic levitation swing motor provided by the present utility model, when the stator coil 22 is connected to alternating current, under the action of magnetic induction, it will drive the mover 3 and the swing frame 5 to swing reciprocally, so as to achieve power output. During the reciprocating swing of the swing frame 5, it will be affected by the elastic forces of the return spring 6 and the elastic piece 4, so as to achieve high-speed reciprocating motion. The specific working principle of the magnetic levitation swing motor provided by the present utility model is basically the same as that of the prior art (such as a brushless electromagnetic levitation vibration motor disclosed in the Chinese invention patent application with the publication number of CN114123702A), so it will not be elaborated here.

[0041] Compared with the prior art, for the magnetic levitation swing motor provided by the present utility model, by optimizing and improving the structure of the motor, for example, using an integral support frame 1 to replace the separately arranged bottom corner supports, front support frames, rear support rod frames and limit seats in the prior art, and for another example, canceling the elastic piece connecting seat in the prior art, etc., the number of parts required for the whole machine is effectively reduced, making the whole machine structure simple and reasonable, not only effectively reducing the production and manufacturing cost, but also being beneficial to reducing the assembly difficulty, thereby improving the assembly efficiency.

[0042] Preferably, in this embodiment, for the convenience of the fixed connection between the stator coil assembly 2 and the base 12, clamping protrusions 212 are arranged on both sides of the bottom of the stator 21, and the base 12 is provided with clamping grooves 121 corresponding to the clamping protrusions 212, and the stator 21 is clamped to the base 12 through the clamping protrusions 212 and the clamping grooves 121. Grooves 213 are arranged on both sides of the bottom of the stator 21, and the base 12 is provided with clamping edges 122 corresponding to the grooves 213, and the stator 21 is clamped to the base 12 through the grooves 213 and the clamping edges 122.

[0043] Preferably, in order to reduce the vibration generated during the operation of the motor, such as Figure 3As shown, two swing frames 5 are arranged above the stator coil assembly 2, side by side in the horizontal direction. Each swing frame 5 has a mover 3 at its bottom. The tops of the bosses 51 of the two swing frames 5 are connected to a limiting link 7. In this embodiment, there is one limiting link 7 located at the top center of the swing frame 5. Both ends of the limiting link 7 are provided with swing limiting grooves 71, which are oblong grooves. Each boss 51 is provided with a limiting pin 511 that corresponds to and engages with the corresponding swing limiting groove 71. The support frame 1 also includes a mounting base 15 located on the top of the frame body 11. The mounting base 15 has a mounting shaft 151, and the middle part of the limiting link 7 is rotatably connected to the mounting shaft 151. When the stator coil 22 is energized, the two swing frames 5 always swing in opposite directions, thereby reducing motor vibration. During the reverse swinging process of the two swing frames 5, the limiting link 7 effectively limits the swing stroke of the swing frames 5.

[0044] Furthermore, in this embodiment, an output shaft 52 is provided on the boss 51 of one of the swing frames 5. When the motor is working, the swing frame 5 can realize power output through the output shaft 52. In order to further simplify the number of required accessories, the output shaft 52 also serves as the limiting pin 511 provided on the corresponding boss 51.

[0045] Preferably, in order to improve the magnetic induction effect and thus increase the output torque of the motor, such as... Figure 2 As shown in this embodiment, two movers 3 are arranged side by side in the horizontal direction at the bottom of each swing frame 5. For each swing frame 5, the two movers 3 on the same swing frame 5 are linearly arranged along the length of the swing frame 5, and the two movers 3 are symmetrically arranged with respect to the bottom center of the swing frame 5. Of course, in other embodiments, the number of movers 3 at the bottom of each swing frame 5 may be only one, in which case the mover 3 is located at the bottom center of the swing frame 5. In addition, it should be noted that regardless of whether one or two movers 3 are provided at the bottom of the swing frame 5, the magnetic pole distribution direction of the movers 3 (i.e., the orientation of the magnetic poles of the movers 3) during installation is common knowledge to those skilled in the art, and therefore will not be elaborated here.

[0046] Preferably, in this embodiment, the inner side of the connecting seat 13 is provided with a spring seat 8 that abuts against the return spring 6. By providing the spring seat 8, it is not only convenient to install and position the return spring 6, but also to make the return spring 6 more stable when the motor is working.

[0047] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
