Description

Technical Field

[0001] The utility model belongs to the technical field of coupled inductor devices, and in particular relates to a novel coupled inductor device. Background Art

[0002] Coupled inductors are mainly visualized through magnetic circuit coupling and circuit coupling. In the process of realizing magnetic circuit coupling, it is mainly based on the magnetic field interaction between inductor elements. When two or more inductor elements are close to each other, they form a coupling relationship through the magnetic field. In practical applications, it is necessary to adjust the coupling degree of coupled inductors according to specific application scenarios and needs. The existing adjustment method mainly changes the magnetic field distribution and coupling strength between them by changing the distance, angle or alignment between the inductors. The change of the distance, angle or alignment between the inductors is used to adjust the coupling strength. The inductor has a large mobile adjustment, which requires sufficient adjustment space between two or more inductor elements.

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model.

[0022] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which the present invention belongs. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items. Example 1

[0024] See also Figure 1-Figure 4 , a novel coupled inductor device shown in the figure includes a first inductor 101 and a second inductor 102, two oppositely arranged middle columns 103 are arranged between the first inductor 101 and the second inductor 102, and also includes an adjustment component arranged on the two middle columns 103 for adjusting the coupling degree between the first inductor 101 and the second inductor 102;

[0025] The adjustment component includes two L-shaped plates 201 fixedly connected to the two middle columns 103 near the first inductor 101 and the second inductor 102. An adjustment box 202 is provided between the two L-shaped plates 201 on the same side. A rotating shaft 203 is rotatably connected in the two adjustment boxes 202. The side walls of the two rotating shafts 203 are rolled with iron sheets 204. One end of the two iron sheets 204 is connected to the rotating shaft 203. One of the two middle columns 103 is provided with a driving component for driving the two iron sheets 204.

[0026] It should be noted here that: through the setting of the adjustment component, under the action of the driving component and the rewinding component, the iron sheet 204 is used to change the relative area of ​​the middle column 103, thereby realizing the adjustment of the coupling degree between the first inductor 101 and the second inductor 102, and the iron sheet 204 realizes the change of the relative area of ​​the middle column 103 by winding and pulling, so that less adjustment space is occupied, so that the relative area of ​​the middle column 103 can be freely adjusted, thereby ensuring the effect of coupling adjustment of the inductor device.

[0027] What needs to be emphasized is that: because iron can conduct magnetism, it can play the role of magnetic isolation. The magnetic permeability of iron is very large, that is to say, the magnetic field is more willing to flow inside the iron than the air magnetic field. Therefore, when iron is placed on one side of the magnetic field, the magnetic lines of force are more closed inside the iron, and the magnetic field on the other side of the iron is very small, thus playing the role of magnetic isolation and further changing the magnetic resistance.

[0028] See also Figure 4 , the two adjustment boxes 202 shown in the figure have adjustment holes 205 on opposite sides, and the two iron sheets 204 are slidably connected to the adjustment holes 205;

[0029] It should be noted here that: the setting of the adjustment hole 205 can, on the one hand, facilitate the removal or rewinding of the iron sheet 204 from the adjustment box 202 , and on the other hand, provide guidance and limit for the movement of the iron sheet 204 .

[0030] See also Figure 3 The driving assembly shown in the figure includes two first fixing plates 301 fixedly connected to one side of the middle column 103 and arranged symmetrically with each other, a double-headed threaded rod 302 is rotatably connected between the two first fixing plates 301, and the side walls of the two double-headed threaded rods 302 are respectively threadedly connected to two driving plates 303, and the other ends of the two iron sheets 204 are fixedly connected to a connecting plate 304, one end of the two driving plates 303 is connected to the connecting plate 304, one of the two first fixing plates 301 is provided with a motor 305, and the output end of the motor 305 is connected to the double-headed threaded rod 302, and the middle column 103 is provided with a guide assembly for guiding the movement of the connecting plate 304;

[0031] It should be noted here that: by setting the driving assembly, it is convenient to drive the opposite ends of the two iron sheets 204 to move towards or away from each other.

[0032] See also Figure 4 The guide assembly shown in the figure includes two second fixing plates 401 which are fixedly connected to the side of the middle column 103 away from the double-headed threaded rod 302 and are symmetrically arranged with each other. A guide rod 402 is fixedly connected between the two second fixing plates 401. The guide rod 402 is slidably connected to two guide plates 403. One end of the two guide plates 403 is connected to the connecting plate 304.

[0033] It should be noted here that: by setting the guide component, a guiding and limiting function is provided for the movement of the connecting plate 304.

[0034] See also Figure 4 , the guide rod 402 and the double-threaded rod 302 are symmetrically arranged;

[0035] It should be noted here that the guide rod 402 and the double-threaded rod 302 are symmetrically arranged to improve the movement stability of the connecting plate 304.

[0036] Working principle: When the coupled inductor device is in use, the middle column 103 is used to couple the first inductor 101 and the second inductor 102. If the magnetic resistance of the middle column 103 is zero, the first inductor 101 and the second inductor 102 are essentially not coupled. If the magnetic resistance of the middle column 103 continues to increase, the coupling degree between the first inductor 101 and the second inductor 102 will continue to increase.

[0037] In actual use, it is necessary to adjust the coupling degree of the coupling inductor according to the specific application scenarios and needs. In the process of adjustment, by starting the motor 305, the double-headed threaded rod 302 is driven to rotate, and the threaded engagement transmission of the double-headed threaded rod 302 and the driving plate 303 and the guiding action of the guide component will drive the two connecting plates 304 to move closer to or away from each other, thereby further pulling and rewinding the iron sheet 204 under the action of the pulling force and the rewinding component, thereby changing the relative area of ​​the two middle columns 103 by pulling and rewinding the iron sheet 204. Since a larger relative area can provide more channels for the magnetic flux, the magnetic flux density is reduced, thereby reducing the magnetic resistance. On the contrary, a smaller relative area will limit the flow of magnetic flux and increase The magnetic flux density leads to an increase in magnetic resistance. Therefore, when the magnetic resistance of the middle column 103 increases, it is more difficult for the magnetic field to pass through the middle column 103, resulting in more magnetic field lines concentrated between the inductor coils, thereby enhancing the degree of coupling between them. On the contrary, when the magnetic resistance decreases, the magnetic field is more likely to pass through the middle column 103, making the distribution of the magnetic field lines between the inductor coils more dispersed, thereby weakening the degree of coupling. The coupling degree of the first inductor 101 and the second inductor 102 is adjusted by changing the relative area of ​​the middle column 103, and the iron sheet 204 changes the relative area of ​​the middle column 103 by winding and pulling, so that less adjustment space is occupied, so that the relative area of ​​the middle column 103 can be freely adjusted, thereby ensuring the effect of coupling adjustment of the inductor device. Example 2

[0038] See also Figure 3 and Figure 4 , this embodiment further explains Example 1, the two regulating boxes 202 shown in the figure are provided with a rewinding assembly for rewinding the iron sheet 204, the rewinding assembly includes a T-shaped rewinding plate 501 arranged on one side of the regulating box 202, one end of the rotating shaft 203 penetrates the regulating box 202 and is connected to the T-shaped rewinding plate 501, a torsion spring 502 is provided on the side wall of the T-shaped rewinding plate 501, and the two ends of the torsion spring 502 are respectively connected to the T-shaped rewinding plate 501 and the regulating box 202;

[0039] It should be noted here that: when the two connecting plates 304 move away from each other to increase the relative area of ​​the two middle columns 103, under the elastic action of the torsion spring 502, the iron sheet 204 will be driven to be wound onto the side wall of the rotating shaft 203, thereby storing the iron sheet 204, ensuring the neatness of the storage of the iron sheet 204, thereby increasing the multiple use rate of the iron sheet 204.

Therefore, any minor modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
