[0068] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments.

[0069] In the description of the present application, it should be understood that, unless otherwise defined, all technical and scientific terms used in the present application have the same meaning as those commonly understood by those skilled in the art of the present application. In addition, any terminology used is only for the purpose of describing specific embodiments and is not intended to limit the present application.

It should be understood by those skilled in the art that the present application can also be implemented without certain specific details. In some examples, methods, means, components and circuits well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present application.

[0071] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0072] Embodiment 1

[0073] In view of the defects of the above-mentioned prior art, the applicant, based on many years of rich practical experience and professional knowledge in the design and manufacture of such products, and in conjunction with the application of theory, actively conducts research and innovation in the hope of creating a technology that can solve the defects of the prior art and make the magnetic integrated inductor more practical. After continuous research and design, and after repeated trial production and improvement, the present utility model with real practical value was finally created.

[0074] The present invention provides a magnetic integrated inductor. Figure 1 , the magnetic integrated inductor comprises:

[0075] An upper top plate 1, a lower bottom plate 2, a left column 3, a right column 4, N winding columns 5, N coils 6 and N-1 middle columns 7, where N is a natural number ≥ 2;

[0076] The left column 3, N-1 middle columns 7 and the right column 4 are arranged in sequence between the upper top plate 1 and the lower bottom plate 2;

[0077] A winding post 5 is provided between the left post 3 and an adjacent middle post 7, a winding post 5 is provided between the right post 4 and an adjacent middle post 7, and a winding post 5 is provided between every two adjacent middle posts 7;

[0078] One coil 6 is correspondingly wound on one winding post 5;

[0079] It should be noted that, in this embodiment, the middle columns 7 corresponding to the left column 3 and the right column 4 are merged so that the left column 3 and the right column 4 can share one middle column 7, thereby further reducing the loss of the two side columns, and the total weight and volume of the inductor are also reduced.

[0080] Or, please refer to Figure 2 and Figure 11-12 , the magnetic integrated inductor comprises:

[0081] An upper top plate 1, a lower bottom plate 2, M winding poles 5, M coils 6 and M middle poles 7, where M is a natural number ≥ 3;

[0082] M middle pillars 7 are arranged around and between the upper top plate 1 and the lower bottom plate 2;

[0083] One winding post 5 is provided between each two adjacent middle posts 7;

[0084] One coil 6 is correspondingly wound on one winding pole 5 .

[0085] It should be noted that Figure 2 It can be regarded as Figure 1 The left column 3 and the right column 4 are merged so that the left column 3 and the right column 4 become a middle column 7. The premise of this improvement is that several middle columns 7 are arranged around, so that there is no need to divide them into the rightmost end and the leftmost end, which can further reduce the total weight, total volume and total loss of the inductor.

[0086] Please refer again Figure 1-2 In this embodiment, X air gaps 8 are provided on all the winding posts 5;

[0087] Alternatively, X air gaps 8 are provided on some of the winding poles 5, where X is a natural number ≥0.

[0088] It should be noted that the winding column 5 may have no air gap 8 or may have one or more air gaps. The number and height of the air gaps 8 can adjust the inductance and the amount of leakage flux.

[0089] Optionally, the air gap 8 may be filled with air or a material with low magnetic permeability.

[0090] Regarding the structural design of the upper top plate 1 and the lower bottom plate 2, on the one hand, they can be an integral structure, and on the other hand, they can be a combined structure.

[0091] Please refer again Figure 1 In this embodiment, the upper top plate 1 may be an integral structure, and the top surfaces of the left column 3, the middle column 7 and the right column 4 are in contact with the bottom surface of the upper top plate 1;

[0092] Please refer to Figure 3 In this embodiment, the upper top plate 1 may include a plurality of upper top sub-plates 11 in combination, the top surfaces of the left column 3 and the right column 4 are in contact with the bottom surface of the upper top plate 1 (or the top surface of the left column 3 is in contact with the bottom surface of the upper top plate 1, and the top of the right column 4 is in contact with the side surface of the upper top plate 1), and the top of each of the middle columns 7 is in contact with the side surfaces of the corresponding two upper top sub-plates 11.

[0093] It should be noted that the top plate 1 plays an important role in the magnetic integrated inductor. It can be an integral structure or a structure formed by a combination of multiple parts. Regardless of its specific structure, the main function of the top plate 1 is to provide the structural support and magnetic circuit required for the magnetic integrated inductor. Therefore, whether the top plate 1 is an integral structure or a combined structure, as long as it can effectively provide the magnetic circuit and support, the magnetic integrated inductor it constitutes can produce the same effect.

[0094] Please refer again Figure 1 In this embodiment, the lower base plate 2 may be an integral structure, and the bottom surfaces of the left column 3, the middle column 7 and the right column 4 are in contact with the top surface of the lower base plate 2;

[0095] Please refer to Figure 4 In this embodiment, the lower base plate 2 may include a plurality of lower base plates 21 in combination, the bottom surfaces of the left column 3 and the right column 4 are in contact with the top surface of the lower base plate 2 (or the bottom surface of the left column 3 is in contact with the top surface of the lower base plate 2, and the bottom of the right column 4 is in contact with the side surface of the lower base plate 2), and the bottom of each of the middle columns 7 is in contact with the side surfaces of the corresponding two lower base plates 21.

[0096] It should be noted that the lower base plate 2 plays an important role in the magnetic integrated inductor. It can be an integral structure or a structure formed by a combination of multiple parts. Regardless of its specific structure, the main function of the lower base plate 2 is to provide the structural support and magnetic circuit required for the magnetic integrated inductor. Therefore, whether the lower base plate 2 is an integral structure or a combined structure, as long as it can effectively provide the magnetic circuit and support, the magnetic integrated inductor it constitutes can produce the same effect.

[0097] Please refer to Figure 5In this embodiment, the upper top plate 1 may include a plurality of upper top sub-plates 11 in combination, the top surfaces of the left column 3 and the right column 4 are in contact with the bottom surface of the upper top plate 1, and the top of each of the middle columns 7 is in contact with the side surfaces of the corresponding two upper top sub-plates 11. At the same time, the lower bottom plate 2 may include a plurality of lower bottom sub-plates 21 in combination, the bottom surfaces of the left column 3 and the right column 4 are in contact with the top surface of the lower bottom plate 2 (or the bottom surface of the left column 3 is in contact with the top surface of the lower bottom plate 2, and the bottom of the right column 4 is in contact with the side surface of the lower bottom plate 2), and the bottom of each of the middle columns 7 is in contact with the side surfaces of the corresponding two lower bottom plates 21.

[0098] In this embodiment, the winding directions of the coils 6 on each of the winding poles 5 are the same or opposite.

[0099] It should be noted that in Figure 1 On the basis of Figure 6-8 As shown, when the winding direction of coil 6 is the same, Figure 6 is the magnetic flux path of the rightmost coil 6 in the magnetic core, Figure 7 is the magnetic flux path of the middle coil 6 in the magnetic core, Figure 8 It is the magnetic flux path of the leftmost coil 9 in the magnetic core. From these three figures, it can be seen that the magnetic flux in the middle column 7 cancels each other out. As a result, the magnetic flux density of the middle column 7 is lower than that of a single inductor. Therefore, the cross-sectional area of ​​the middle column 7 can be reduced, the inductance loss can be reduced, and the inductance weight can be reduced.

[0100] exist Figure 2 On the basis of Fig. 9 As shown, if the winding directions of the coils 6 are the same, the dashed line with an arrow is the magnetic flux path of the coil 6 in the magnetic core, and the solid line with an arrow is the magnetic flux path of the adjacent coils 6 in the magnetic core. Fig. 9 It can be seen that the magnetic fluxes in all the middle columns 7 cancel each other out. As a result, the magnetic flux density of all the middle columns 7 is lower than that of a single inductor. Therefore, the cross-sectional area of ​​the middle column 7 can be reduced, the inductance loss can be reduced, and the inductance weight can be reduced.

[0101] In this embodiment, both ends of each winding pole 5 may be in contact with the two middle poles 7 , or may be in contact with the upper top plate 1 and the lower bottom plate 2 , or may be in contact with the left pole 3 (or the right pole 4 ) and the middle pole 7 .

[0102] The lower base plate 2 may be an integral structure, and the bottom surfaces of the left column 3, the middle column 7 and the right column 4 are in contact with the top surface of the lower base plate 2;

[0103] Please refer again Figure 1In this embodiment, on one hand, one end of the winding pole 5 located at the leftmost end contacts the left pole 3, and the other end contacts the middle pole 7; one end of the winding pole 5 located at the rightmost end contacts the right pole 4, and the other end contacts the middle pole 7; both ends of the remaining winding poles 5 contact the middle pole 7 respectively;

[0108] On the other hand, one end of some of the winding poles 5 is in contact with the upper top plate 1, and the other end is in contact with the lower bottom plate 2; both ends of some of the winding poles 5 are respectively in contact with the middle pole 7; one end of the winding pole 5 located at the far left is in contact with the left pole 3, and the other end is in contact with the middle pole 7; one end of the winding pole 5 located at the far right is in contact with the right pole 4, and the other end is in contact with the middle pole 7.

These terms are used only to more conveniently describe and explain the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.

[0110] The utility model provides a magnetic integrated inductor, which, through a special structural design, can further reduce the overall volume, weight and loss of the inductor, so as to further obtain a better electromagnetic compatibility effect, achieve a higher power density, improve the inductor performance, and facilitate the promotion and application of the inductor.
