Description

[Technical Field]

[0001] The present invention relates to a magnetic assembly, and more particularly to a magnetic assembly in which a resilient device is arranged in a compressed state to effectively reduce noise and improve operational performance. [Background technology]

[0002] With the continuous advancement of science and technology, electronic products are increasingly integrated into our lives. The trend toward thinner, lighter, and more efficient products has created unprecedented demands and sensory experiences. Magnetic assemblies are one of the key components of electronic products, and reducing their volume makes them easier to place and integrate in limited spaces. The demand for higher power in the consumer market has led to multiple small magnetic assemblies being placed closer together, increasing the magnetic flux interference between them and accumulating and amplifying heat and noise. The technology required to maintain each magnetic assembly in a stable operating environment and extend its lifespan is becoming increasingly demanding.

[0003] Currently, a common approach to solving the problem of noise caused by vibration in magnetic assemblies is to fill the magnetic assembly with soft adhesive. However, this technique can only absorb a small portion of light vibrations, and most of the noise generated by vibration is still transmitted to the outside through the soft adhesive. The soft adhesive is dispersed throughout the filled area using pressure during assembly. In mass production, controlling the direction of diffusion is difficult, leading to localized insufficient adhesive filling and uneven thickness, which directly affects the uniformity of the finished product. Furthermore, soft adhesives are susceptible to degradation due to environmental factors, which can affect their expected performance.

[0004] In view of this, how to provide a magnetic assembly that can solve the drawbacks of the prior art through the design and assembly of a noise reduction mechanism has become an urgent problem to be solved. Summary of the Invention [Problem to be solved by the invention]

[0025] FIG. 1 is a schematic structural diagram of a magnetic assembly according to a first embodiment of the present invention. FIG. 2 is an exploded structural diagram of the magnetic assembly according to the first embodiment of the present invention. FIG. 3 is a cross-sectional view of a first core and a second core according to the first embodiment of the present invention. In this embodiment, the magnetic assembly 1 includes a first core 10, a second core 20, a coil device 30, and at least one resilient device 40. The first core 10 includes a first groove surface 101, and the second core 20 includes a second groove surface 201, which correspond to each other to form an accommodating space 50. The coil device 30 and the at least one resilient device 40 are disposed within the accommodating space 50. During the assembly process of the magnetic assembly 1, pressing the resilient device 40 within the accommodating space 50 can reduce noise caused by vibration of the magnetic assembly 1 during operation and improve the stability of the operating environment of the magnetic assembly 1.

[0026] FIG. 4 is a cross-sectional view of the magnetic assembly according to the first embodiment of the present invention. FIG. 5 is a side cross-sectional view of the magnetic assembly according to the first embodiment of the present invention. FIG. 6 is a side cross-sectional view of the elastic device according to the first embodiment of the present invention. In this embodiment, the coil device 30 is composed of a bobbin 303 and a winding L. The coil device 30 includes a first coil device surface 3001 and a second coil device surface 3002. In this embodiment, the first coil device surface 3001 is the upper surface 3031 of the bobbin, and the second coil device surface 3002 is the lower surface 3032 of the bobbin. During the assembly process of the magnetic assembly 1, the elastic device 40 is compressed in the first direction z, changing its original thickness T to a compressed thickness H, thereby achieving a tight structure. When the compressed thickness H is 50% or less of the original thickness T of the elastic device, the noise reduction effect can be improved and can replace the conventional technique of filling the second groove surface 201 with a soft adhesive. In the prior art, after the soft adhesive is locally dotted on the second groove surface 201, the soft adhesive spreads outward due to the pressing force from the first direction z during the assembly process of the magnetic assembly 1. Because the directionality is difficult to control, the soft adhesive is unevenly distributed on the second groove surface 201, affecting noise isolation. Furthermore, the liquid component contained in the soft adhesive is prone to degradation over time and in the environment, resulting in unstable quality of the magnetic assembly 1. In this embodiment, the elastic device 40 is a solid structure designed to completely cover the second groove surface 201. After being pressed during the assembly process, the elastic device 40 can adhere more closely to the second groove surface 201, improving the yield of the product process during mass production.

[0027] 5 and 6. In this embodiment, the elastic device 40 includes a shielding structure 401, which is made of aluminum oxide, silicon oxide, magnesium oxide, or a composite material thereof. The outer surface 4011 of the shielding structure is in contact with the bottom surface 3032 of the bobbin, thereby blocking leakage magnetic flux generated during operation of the magnetic assembly 1 and preventing it from affecting the operation of the entire magnetic assembly 1, thereby reducing magnetic flux interference and improving the performance of the magnetic assembly. The elastic device 40 includes an elastic member 402, which allows the outer surface 4011 of the shielding structure to be more closely attached to the bottom surface 3032 of the bobbin when the elastic device 40 is pressed, further improving the effect of blocking leakage magnetic flux.

[0028] 5 and 6. In this embodiment, the elastic device 40 includes a magnetic flux guide structure 403 made of an iron core with nano-sized crystals, and the outer surface 4031 of the magnetic flux guide structure is in contact with the second groove surface 201. The effective cross-sectional area of ​​the core is increased, increasing the amount of magnetic flux, and the material properties allow the magnetic flux to be guided in a desired direction. The elastic device 40 includes an elastic member 402, which allows the outer surface 4031 of the magnetic flux guide structure to be more closely attached to the second groove surface 201 when the elastic device 40 is pressed, further improving magnetic conduction efficiency.

[0029] In addition, the elastic device 40 used in the present invention is made of a composite material, and the shielding structure 401, the elastic member 402, and the magnetic flux guide structure 403 are laminated and integrated, which simplifies the assembly process of the magnetic assembly 1 and improves the process yield.

[0030] Referring to Figure 4, in this embodiment, the first side pillar 103 of the first core 10 is connected to the first groove surface 101, and the second side pillar 203 of the second core 20 is connected to the second groove surface 201. The first side pillar 103 of the first core 10 and the second side pillar 203 of the second core 20 are connected to each other with a hard adhesive to form a first side pillar P1. The first side pillar P1 not only guides magnetic flux, but also serves to further block noise generated during operation of the magnetic assembly 1.

[0031] 2, in this embodiment, the resilient device 40 includes a resilient device protrusion 405, and the side pillar P includes a side pillar groove N. The side pillar groove N of the side pillar P engages with the resilient device protrusion 405 to limit the rotation of the resilient device 40, thereby improving the consistency of the production quality of the magnetic assembly 1 and increasing the yield rate.

[0032] Referring to FIGS. 1 and 4, the first side column P1 on the left side of the magnetic assembly 1 is composed of a first side column 103 and a second side column 203. The first side column and the second side column on the right side of the magnetic assembly 1 constitute a second side column P2. In another embodiment, the first core 10 and the second core 20 are each L-shaped cores, and the first side column is composed of the side column of one L-shaped core, and the second side column is composed of the side column of the other L-shaped core, but the present invention is not limited thereto. In this embodiment, the side column P of the magnetic assembly 1 includes a first side column P1 and a second side column P2, and a first opening S1 and a second opening S2 are provided between the first side column P1 and the second side column P2, respectively. The first opening S1 and the second opening S2 are positioned opposite each other, which effectively forms convection through heat transfer and allows hot air to be efficiently discharged.

[0033] 2 and 3, in this embodiment, the elastic device 40 includes a through-hole 400, which is positioned corresponding to the first intermediate pillar 102 and / or the second intermediate pillar 202 of the magnetic assembly 1. During the assembly process of the magnetic assembly 1, the first intermediate pillar 102 and / or the second intermediate pillar 202 of the magnetic assembly 1 can be accurately positioned through the through-hole 400 of the elastic device 40, thereby improving the yield of the production line.

[0034] FIG. 7 is a structural three-dimensional diagram of a magnetic assembly according to a second embodiment of the present invention. FIG. 8 is a structural exploded view of a magnetic assembly according to a second embodiment of the present invention. In this embodiment, the magnetic assembly 1a is similar to the magnetic assembly 1 shown in FIGS. 1 to 6, and the same reference numerals denote the same elements, structures, and functions. In this embodiment, the coil device 30a is composed of a printed circuit board 304 and a winding L, and the winding L is embedded in the printed circuit board 304. In this embodiment, the first coil device surface 3001 is the upper surface 3041 of the printed circuit board, and the second coil device surface 3002 is the lower surface 3042 of the printed circuit board. Since the coil device 30a is thinner than the coil device 30, the arrangement of the magnetic assembly 1a is easier, and a compact, high-output effect can be achieved. The same effect can be achieved even if the elastic device 40 is provided within the magnetic assembly 1a.

[0035] FIG. 9 is an exploded view of the structure of a magnetic assembly according to a third embodiment of the present invention. In this embodiment, the magnetic assembly 1b is similar to the magnetic assembly 1 shown in FIGS. 1 to 6, and the same reference numerals denote the same elements, structures, and functions. In this embodiment, the elastic device 40 of the magnetic assembly 1b has a two-layer structure, assembled between the first groove surface 101 and the first coil device surface 3001, and between the second groove surface 201 and the second coil device surface 3002. In the assembly process of the magnetic assembly 1b, the two elastic devices 40 are pressed together to be fixedly attached to each other, thereby achieving a further noise reduction effect and enabling the magnetic assembly to meet different requirements.

[0036] FIG. 10 is an exploded view of the structure of a magnetic assembly according to a fourth embodiment of the present invention. In this embodiment, the magnetic assembly 1c is similar to the magnetic assembly 1 shown in FIGS. 1 to 6, and the same reference numerals denote the same elements, structures, and functions. In this embodiment, the elastic device 40c of the magnetic assembly 1c further includes an elastic device extension 404. The elastic device extension 404 extends outside the first opening S1 and is positioned so as not to shield the first core 10 and the second core 20 when viewed from the first direction z. This allows heat generated during operation of the magnetic assembly 1c to be dissipated through the first opening S1 and the second opening S2. The provision of the elastic device extension 404 further increases the heat dissipation area, further improving the stability of the operating environment of the magnetic assembly 1c. This solves the problem of the insufficient support strength of soft adhesives used in the prior art, which made it difficult to realize an extension structure around the magnetic assembly 1c.

[0037] FIG. 11 is an exploded view of the structure of a magnetic assembly according to a fifth embodiment of the present invention. In this embodiment, the magnetic assembly 1d is similar to the magnetic assembly 1 shown in FIGS. 1 to 6, and the same reference numerals denote the same elements, structures, and functions. In this embodiment, the upper and lower surfaces of the elastic device 40d within the magnetic assembly 1d are both flat, allowing for closer contact between the second coil device surface 3002 and the second groove surface 201. Furthermore, because the elastic device 40d is made of a compressible solid material, its appearance can be flexibly adjusted. To improve heat dissipation, noise reduction, magnetic flux conduction, and insulation, the elastic device 40d can be designed to have an undulating shape (as shown in FIG. 8) or a regular wavy shape (as shown in FIG. 6) depending on the appearance of adjacent assemblies and operating environment factors.

[0038] FIG. 12 is a structural exploded view of a magnetic assembly according to a sixth embodiment of the present invention. In this embodiment, the magnetic assembly 1e is similar to the magnetic assembly 1 shown in FIGS. 1 to 6, and the same reference numerals denote the same elements, structures, and functions. In this embodiment, the elastic device 40 of the magnetic assembly 1e is disposed between two coil devices 30. The two coil devices 30 may have the same structure, for example, but are not limited to this. Each coil device 30 has a first coil device surface 3001 and a second coil device surface 3002 on opposite sides thereof. The first coil device surface 3001 is spatially opposed to the first groove surface 101, and the second coil device surface 3002 is spatially opposed to the second groove surface 201. The upper surface of the elastic device 40 faces the second coil device surface 3002 of the upper coil device 30, and the lower surface of the elastic device 40 faces the first coil device surface 3001 of the lower coil device 30, thereby disposing the elastic device 40 between the two coil devices 30. During the assembly process of the magnetic assembly 1e, the elastic device 40 is pressed to fix and adhere between the two coil devices 30, thereby further improving noise reduction, vibration reduction, leakage flux shielding, magnetic flux conduction, and heat dissipation performance, while simplifying the assembly process. Of course, the present invention is not limited to this. While the embodiments of the magnetic assemblies 1, 1a, 1b, 1c, 1d, and 1e of the present invention are applied to transformers, the present invention is not limited thereto, and similar effects can be obtained by applying the technology of the present invention to inductors.

[0039] As described above, the magnetic assembly of the present invention includes a first core, a second core, a coil device, and at least one elastic device. The first core includes a first groove surface, and the second core includes a second groove surface, with the first core and the second core corresponding to each other to form an accommodating space. The coil device and at least one elastic device are disposed within the accommodating space. During the assembly process of the magnetic assembly, the elastic device disposed within the accommodating space is compressed to form a tightly sealed space, thereby reducing noise problems caused by vibration of the magnetic assembly during operation and improving the stability of the magnetic assembly during operation. During the assembly process of the magnetic assembly, the elastic device is compressed from its original thickness before installation to its compressed thickness, thereby achieving a tightly packed structure. A better noise reduction effect can be achieved when the thickness of the elastic device is compressed by 50% or more. The elastic device used in the present invention is made of a composite material, and the magnetic flux guide structure, shielding structure, and elastic member are laminated and integrated, thereby simplifying the assembly process of the magnetic assembly and improving process yield. Furthermore, because the elastic device of the present invention is a solid structure, it is easier to adjust the design than conventional colloidal materials and can accommodate changes in assembly structure and assembly method. The composite elastic device can be adjusted to adapt to changes in environmental factors, an advantage not possible with conventional technologies.
