Description

Magnetic assembly TECHNICAL FIELD

[0001] The present disclosure relates to a magnetic assembly, in particular to a magnetic assembly, by the tight fit of the elastic gasket, effectively reducing noise, while improving operating performance. BACKGROUND

[0002] With the continuous breakthrough of science and technology, electronic products are closer to our life. The trend of thin, light and efficient leads to the demand and sensory experience that has never been touched before. The magnetic assembly is one of the key components of electronic products, and reducing the size of the magnetic assembly is more conducive to configuration and integration in limited space. Under the continuous demand for high power in the consumer market, several small volume magnetic assemblies are closer to each other, resulting in more magnetic flux interference between each other, and the phenomenon of heat dissipation and noise is more likely to be accumulated and amplified. In order to maintain each magnetic assembly in a stable working environment and maintain its service life, the technology is becoming more and more stringent.

[0003] At present, in order to solve the problem of abnormal sound caused by vibration of the magnetic assembly, the common technology is to fill soft glue in the magnetic assembly, which can only absorb a small part of the slight vibration, and most of the noise generated by the vibration will be transmitted to the outside through the soft glue. The soft glue is diffused to the filled area by the assembly pressure, and in the case of mass production, the diffusion direction is not easy to control, so that the local area is easy to lack glue, the thickness control is uneven, and the consistency of the finished product is directly affected. It is worth mentioning that the soft glue is easy to deteriorate in the environment and then affect the expected effect.

[0004] Therefore, how to provide a magnetic assembly by the anti-noise mechanism design and assembly method to solve the lack of known technology is an urgent problem to be solved at present.

[0036] Figure 1 discloses a schematic diagram of a magnetic assembly structure according to a first embodiment of the present disclosure. Figure 2 discloses an exploded view of the magnetic assembly structure. Figure 3 discloses a cross-sectional view of a first magnetic core portion and a second magnetic core portion. In the present embodiment, the magnetic assembly 1 comprises a first magnetic core portion 10, a second magnetic core portion 20, a winding set 30, and at least one elastic pad 40. The first magnetic core portion 10 comprises a first recessed surface 101, and the second magnetic core portion 20 comprises a second recessed surface 201. The first recessed surface 101 and the second recessed surface 201 correspond to each other to form a receiving space 50. The winding set 30 and the at least one elastic pad 40 are arranged in the receiving space 50. Through the assembly process of the magnetic assembly 1, the elastic pad 40 in the receiving space 50 is compressed to tightly fit, so as to reduce the noise problem caused by the vibration of the magnetic assembly 1 when in operation, and to improve the stability of the working environment of the magnetic assembly 1 when in operation.

[0037] Figure 4 discloses a cross-sectional view of the magnetic assembly structure according to the first embodiment of the present disclosure. Figure 5 discloses a side cross-sectional view of the magnetic assembly structure according to the first embodiment of the present disclosure. Figure 6 discloses a side cross-sectional view of the elastic pad according to the first embodiment of the present disclosure. In the present embodiment, the winding set 30 is composed of a winding frame 303 and a winding L. When the original thickness T of the elastic pad is compressed to a compressed thickness H of the elastic pad 40 in the first direction z through the assembly process of the magnetic assembly 1, the elastic pad 40 is tightly fitted. When the compressed thickness H of the elastic pad is less than or equal to 50% of the original thickness T of the elastic pad, the anti-noise effect is improved, and the soft glue filling in the second recessed surface 201 in the prior art is replaced. In the process, the soft glue is partially glued on the second recessed surface 201, and then through the assembly process of the magnetic assembly 1, the soft glue is expanded outwardly under the compression force from the first direction z. Since the directionality is not easy to control, the soft glue is unevenly distributed on the second recessed surface 201, which affects the noise barrier. It should be noted that the soft glue contains liquid components, which is easily affected by the environment and time, and deteriorates, so that the quality of the magnetic assembly 1 is unstable. In the present embodiment, the elastic pad 40 is a solid structure, which is designed to completely cover the second recessed surface 201, and after being compressed through the assembly process, the elastic pad 40 can be more attached to the second recessed surface 201, and the product process yield can be improved in mass production.

[0038] Referring to Figures 5 and 6, in the present embodiment, the elastic pad 40 comprises a shielding structure 401, which is one of aluminum oxide, silicon monoxide, and magnesium monoxide, or a composite thereof. The outer surface 4011 of the shielding structure contacts the bottom surface 3032 of the winding frame, so as to shield the leakage inductance generated when the magnetic assembly 1 is in operation, to avoid affecting the overall operation of the magnetic assembly 1, thereby reducing the magnetic flux interference and improving the efficiency of the magnetic assembly. Since the elastic pad 40 comprises a compression structure 402, when the elastic pad 40 is compressed, the outer surface 4011 of the shielding structure and the bottom surface 3032 of the winding frame are more closely attached, and the shielding effect of the leakage inductance is further improved.

[0039] Referring to FIG. 5 and FIG. 6. In this embodiment, the elastic gasket 40 comprises a magnetic conductive structure 403, which is a nanoscale magnetic core. The outer surface 4031 of the magnetic conductive structure contacts the second groove surface 201. Since the effective cross-sectional area of the magnetic core is increased, the magnetic flux is also increased. In addition, the material can guide the magnetic flux to the desired direction due to its properties. Since the elastic gasket 40 comprises a compression structure 402, when the elastic gasket 40 is compressed, the outer surface 4031 of the magnetic conductive structure can be more closely attached to the second groove surface 201, further improving the magnetic conductive efficiency.

[0040] It is worth mentioning that the elastic gasket 40 used in this disclosure is a composite, which is a stack of shielding structure 401, compression structure 402 and magnetic conductive structure 403. This simplifies the assembly process of the magnetic assembly 1 and improves the process yield.

[0041] Referring to FIG. 4. In this embodiment, the first edge column 103 of the first magnetic core part 10 is connected with the first groove surface 101, and the second edge column 203 of the second magnetic core part 20 is connected with the second groove surface 201. The first edge column 103 of the first magnetic core part 10 and the second edge column 203 of the second magnetic core part 20 are connected with each other by corresponding hard glue to form a first edge column body P1. The first edge column body P1 not only serves as a magnetic conductive structure for the magnetic flux, but also further blocks the noise generated during the operation of the magnetic assembly 1.

[0042] Referring to FIG. 2. In this embodiment, the edge column body groove N of the edge column body P and the protruding part 405 of the elastic gasket 40 are engaged to limit the rotation of the elastic gasket 40, thereby improving the production quality consistency of the magnetic assembly 1 and improving the yield.

[0043] Referring to FIG. 1 and FIG. 4. The first edge column body P1 on the left side of the magnetic assembly 1 is formed by the first edge column 103 and the second edge column 203. In addition, the first edge column and the second edge column on the right side of the magnetic assembly 1 also form a second edge column body P2. In other embodiments, the first magnetic core part 10 and the second magnetic core part 20 are each an L-shaped magnetic core. Therefore, the first edge column body is formed by the edge column of one of the L-shaped magnetic cores, and the second edge column body is formed by the edge column of the other L-shaped magnetic core. The present disclosure is not limited to this. In this embodiment, the edge column body P of the magnetic assembly 1 comprises the first edge column body P1 and the second edge column body P2, and the first edge column body P1 and the second edge column body P2 respectively comprise a first opening S1 and a second opening S2. The first opening S1 and the second opening S2 are arranged on the opposite sides, which effectively forms a convection of heat transfer, so that the hot air can be effectively discharged.

[0044] Referring to FIG. 2 and FIG. 3. In this embodiment, the elastic pad 40 comprises a through hole 400 corresponding to the first center column 102 and / or the second center column 202 of the magnetic assembly 1. During the assembly process of the magnetic assembly 1, the first center column 102 and / or the second center column 202 of the magnetic assembly 1 can be accurately aligned or connected through the through hole 400 of the elastic pad 40, so as to improve the yield of the production line.

FIG. 8 discloses a structure exploded view of the magnetic assembly of the second embodiment of the present disclosure. In this embodiment, the magnetic assembly 1a is similar to the magnetic assembly 1 shown in FIG. 1 to FIG. 6, and the same component reference numerals represent the same components, structures and functions. In this embodiment, the winding set 30a is composed of a printed circuit board 304 and a winding L. The thickness of the winding set 30a is thinner than that of the winding set 30, so that the magnetic assembly 1a can be more easily configured, achieving the effect of small volume and high power. The elastic pad 40 is arranged in the magnetic assembly 1a, which can also achieve the same effect.

[0046] FIG. 9 discloses a structure exploded view of the magnetic assembly of the third embodiment of the present disclosure. In this embodiment, the magnetic assembly 1b is similar to the magnetic assembly 1 shown in FIG. 1 to FIG. 6, and the same component reference numerals represent the same components, structures and functions. In this embodiment, the elastic pad 40 of the magnetic assembly 1b is double-layered, respectively arranged between the first recessed surface 101 and the first winding set surface 3001, and between the second recessed surface 201 and the second winding set surface 3002, and the two elastic pads 40 are compressed and fixed tightly during the assembly process of the magnetic assembly 1b, further achieving the anti-noise effect, which can meet the different needs of application.

[0047] FIG. 10 discloses a structure exploded view of the magnetic assembly of the fourth embodiment of the present disclosure.

In this embodiment, the elastic pad 40c of the magnetic assembly 1c further comprises an elastic pad extension 404 extending outward from the first opening S1, and the elastic pad extension 404 is arranged in a staggered manner with the first magnetic core portion 10 and the second magnetic core portion 20 in the first direction z, so that the heat generated during the operation of the magnetic assembly 1c can be dissipated through the first opening S1 and the second opening S2, and the setting of the elastic pad extension 404 can further improve the heat dissipation surface area, further improve the stability of the working environment of the magnetic assembly 1c, and solve the problem of insufficient support of the soft adhesive in the prior art, which cannot achieve the extension structure outside the magnetic assembly 1c.

[0048] Referring to FIG. 11, a structural exploded view of a magnetic assembly of a fifth embodiment of the present disclosure is disclosed. In this embodiment, the magnetic assembly 1d is similar to the magnetic assembly 1 shown in FIGS. 1-6, and the same component reference numerals represent the same components, structures, and functions. In this embodiment, the upper surface and the lower surface of the elastic gasket 40d in the magnetic assembly 1d are flat, which enables the second winding group surface 3002 and the second recess surface 201 to be more closely fitted. Moreover, since the elastic gasket 40d is a compressible solid material, it has the function of flexibly adjusting the shape. In order to achieve the effects of heat dissipation, noise reduction, magnetic conduction, and insulation, the shape of the elastic gasket 40d is designed to be a high-low surface (as shown in FIG. 8) or a regular wave surface (as shown in FIG. 6) according to the shape of the adjacent assembly or the working environment.

[0049] Referring to FIG. 12, a structural exploded view of a magnetic assembly of a sixth embodiment of the present disclosure is disclosed. In this embodiment, the magnetic assembly 1e is similar to the magnetic assembly 1 shown in FIGS. 1-6, and the same component reference numerals represent the same components, structures, and functions. In this embodiment, the elastic gasket 40 of the magnetic assembly 1e is sandwiched between two winding groups 30. The two winding groups 30 may, for example but not limited to, have the same structure. Each winding group 30 has a first winding group surface 3001 and a second winding group surface 3002 on opposite sides, the first winding group surface 3001 faces the first recess surface 101 in space, and the second winding group surface 3002 faces the second recess surface 201 in space. The top surface of the elastic gasket 40 is opposite to the second winding group surface 3002 of the upper winding group 30, and the bottom surface of the elastic gasket 40 is opposite to the first winding group surface 3001 of the lower winding group 30, so that the elastic gasket 40 is located between the two winding groups 30. During the assembly process of the magnetic assembly 1e, the elastic gasket 40 is compressed and fixedly fitted between the two winding groups 30, thereby further providing the effects of noise reduction, shockproof, shielding of stray magnetic fields, improving magnetic conduction or heat dissipation, and simplifying the assembly process. Of course, the present disclosure is not limited thereto.

[0050] In summary, the magnetic assembly of the present disclosure comprises a first magnetic core portion, a second magnetic core portion, a winding set, and at least one elastic gasket. The first magnetic core portion comprises a first recessed surface and the second magnetic core portion comprises a second recessed surface, which correspond to each other to form a receiving space. The winding set and the at least one elastic gasket are arranged in the receiving space. Through the assembly process of the magnetic assembly, the elastic gasket in the receiving space is compressed to form a closed space, so as to reduce the noise problem caused by vibration of the magnetic assembly when it is actuated, and improve the stability of the magnetic assembly when it is actuated. The elastic gasket is compressed from the original thickness of the elastic gasket before installation to the compressed thickness of the elastic gasket during the assembly process of the magnetic assembly, and at this time, the elastic gasket is tightly arranged. When the compression rate of the thickness of the elastic gasket is greater than or equal to 50%, the anti-noise effect is better. The elastic gasket used in the present disclosure is a composite, which stacks a magnetic conductive structure, a shielding structure, and a compression structure into one body, simplifies the assembly process of the magnetic assembly, and improves the process yield. It is worth mentioning that the elastic gasket of the present disclosure is a solid structure, which is easier to adjust in design compared with the known gel material, and can cope with changes in assembly structure or assembly method. The composite elastic gasket can adjust to changes in environmental factors, which is an effect that cannot be achieved by known technology.
