技术领域Technical field
本发明涉及一种磁芯结构及磁性元件。The invention relates to a magnetic core structure and a magnetic element.
背景技术Background technique
随着大数据、云计算等技术的发展，使得电能的消耗也越来越大，这促使着开关电源技术的快速发展，使得开关电源产品需要具有高效率、高功率密度等特点。但就现有技术而言，磁性元件在整个电源系统中仍占据着较大比例的体积空间以及重量。为了减小磁性器件的体积，通常采取的手段是提升开关电源的工作频率。但是，工作频率的提升会使得与工作频率相关的损耗增加，如开关器件的开关损耗和驱动损耗增加、磁性元件的交流损耗增加等，还会降低开关电源的效率。另外，单纯地提高工作频率，磁性元件的体积存在极限值，此极限体积会限制磁性元件的进一步小型化。With the development of big data, cloud computing and other technologies, the consumption of electric energy is also increasing, which promotes the rapid development of switching power supply technology, making switching power supply products need to have high efficiency, high power density and other characteristics. However, as far as the existing technology is concerned, magnetic components still occupy a large proportion of the volume space and weight of the entire power system. In order to reduce the size of magnetic devices, the usual method is to increase the operating frequency of the switching power supply. However, the increase in operating frequency will increase losses related to operating frequency, such as increased switching losses and driving losses of switching devices, increased AC losses of magnetic components, etc., and will also reduce the efficiency of switching power supplies. In addition, simply increasing the operating frequency will lead to a limit in the volume of magnetic components, and this limit volume will limit further miniaturization of magnetic components.
现有技术中存在一种磁芯结构，包括第一磁盖、第二磁盖、两个绕线柱和一公用边柱。绕线柱和公用边柱设置于第一磁盖与第二磁盖之间，且至少两个绕线柱与公用边柱相对设置，公用边柱朝向绕线柱的侧面具有一凸出部，该凸出部朝向相邻两个绕线柱之间的空隙方向延伸。该技术方案中的磁性元件集成了电感和变压器的功能，容易实现功率扩展，而且有利于避免由于印制电路板层数的增加而导致的散热问题和成本问题等。但是，该技术方案存在以下缺陷：There is a magnetic core structure in the prior art, which includes a first magnetic cover, a second magnetic cover, two winding posts and a common side post. The winding post and the common side post are arranged between the first magnetic cover and the second magnetic cover, and at least two winding posts are arranged opposite to the common side post. The common side post has a protrusion on the side facing the winding post. The protruding portion extends toward the gap between two adjacent winding posts. The magnetic components in this technical solution integrate the functions of inductors and transformers, which can easily achieve power expansion and help avoid heat dissipation problems and cost problems caused by an increase in the number of printed circuit board layers. However, this technical solution has the following shortcomings:
（1）该技术方案给出的绕线方式，使得两个绕线柱的磁通方向是一致的，第一磁盖与第二磁盖中的磁通无抵消。在需要保证磁通密度小的设计场景下，第一磁盖、第二磁盖以及边柱需要具有一定的厚度，才能保证磁通密度小，这实际上不可避免地增加了磁芯结构的体积和重量。(1) The winding method provided by this technical solution makes the magnetic flux directions of the two winding columns consistent, and there is no cancellation of the magnetic fluxes in the first magnetic cover and the second magnetic cover. In a design scenario where the magnetic flux density needs to be low, the first magnetic cover, the second magnetic cover and the side posts need to have a certain thickness to ensure that the magnetic flux density is low, which actually inevitably increases the volume of the magnetic core structure. and weight.
（2）鉴于绕线柱上开设有气隙，因此，绕线柱本身对位于上部的磁盖没有支撑作用，第一磁盖与第二磁盖组合装配时，只能依靠边柱及突出部支撑位于上部的磁盖，但边柱及突出部只位于磁盖的一侧，且沿磁盖长度方向形成细且长的形状，并不能对位于上部的磁盖形成稳固的支撑，没有边柱及突出部的另一侧没有形成对上部磁盖的有效支撑，第一磁盖与第二磁盖组合后的结构不稳定。同时，在某些应用场景下，相邻绕线柱上的绕组需要串联或并联，该专利中的凸起会影响线路布线。(2) Since there is an air gap on the winding column, the winding column itself has no supporting effect on the upper magnetic cover. When the first magnetic cover and the second magnetic cover are combined and assembled, they can only rely on the side posts and protrusions. It supports the upper magnetic cover, but the side pillars and protrusions are only located on one side of the magnetic cover, and form a thin and long shape along the length of the magnetic cover. They cannot form a stable support for the upper magnetic cover. There are no side pillars. The other side of the protruding portion does not form an effective support for the upper magnetic cover, and the structure of the combination of the first magnetic cover and the second magnetic cover is unstable. At the same time, in some application scenarios, the windings on adjacent winding columns need to be connected in series or parallel, and the protrusions in this patent will affect the circuit routing.

具体实施方式Detailed ways
容易理解，依据本发明的技术方案，在不变更本发明的实质精神的情况下，本领域的一般技术人员可以想象出本发明的多种实施方式。因此，以下具体实施方式和附图仅是对本发明的技术方案的示例性说明，而不应当视为本发明的全部或者视为对本发明技术方案的限制或限定。相反，提供这些实施例的目的是为了使本领域的技术人员更透彻地理解本发明。下面结合附图来具体描述本发明的优选实施例，其中，附图构成本申请一部分，并与本发明的实施例一起用于阐释本发明的创新构思。It is easy to understand that according to the technical solutions of the present invention, those of ordinary skill in the art can imagine various implementations of the present invention without changing the essential spirit of the present invention. Therefore, the following specific embodiments and drawings are only illustrative descriptions of the technical solutions of the present invention, and should not be regarded as the entirety of the present invention or as limitations or limitations to the technical solutions of the present invention. Rather, these embodiments are provided so that those skilled in the art will understand the present invention more thoroughly. The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, wherein the drawings constitute a part of this application and are used together with the embodiments of the present invention to illustrate the innovative concepts of the present invention.
图1为本发明所述磁芯结构一个具体实施例的示意图。如图1所示，本实施例所述磁芯结构包括位于上部的第一磁芯盖板A，位于下部的第二磁芯盖板B，两个绕线柱D、E和一个“匚”型边柱C。Figure 1 is a schematic diagram of a specific embodiment of the magnetic core structure of the present invention. As shown in Figure 1, the magnetic core structure in this embodiment includes a first magnetic core cover plate A located at the upper part, a second magnetic core cover plate B located at the lower part, two winding posts D, E and a "博" Type side pillar C.
两个绕线柱D、E和“匚”型边柱C设置在第一磁芯盖板A与第二磁芯盖板B之间。两个绕线柱D、E设置有气隙。其中，“匚”型边柱C包含位于两侧的第一侧边部C1和第二侧边部C2，以及连接于第一侧边部C1与第二侧边部C2之间的第三侧边部C3，第一侧边部C1、第三侧边部C3以及第二侧边部C2依次相连接，形成一个三面包围，一面开口的结构。两个绕线柱D、E设置在“匚”型边柱C内侧，即两个绕线柱D、E位于第一侧边部C1、第三侧边部C3以及第二侧边部C2依次连接形成的三面包围的区域内。The two winding posts D and E and the "博"-shaped side post C are arranged between the first magnetic core cover plate A and the second magnetic core cover plate B. The two winding posts D and E are provided with air gaps. Among them, the "博"-shaped side pillar C includes a first side part C1 and a second side part C2 located on both sides, and a third side connected between the first side part C1 and the second side part C2. The side C3, the first side C1, the third side C3 and the second side C2 are connected in sequence, forming a structure surrounded on three sides and open on one side. Two winding posts D and E are arranged inside the "博"-shaped side post C, that is, the two winding posts D and E are located in the first side part C1, the third side part C3 and the second side part C2 in sequence. Within an area surrounded by three sides.
当第一磁芯盖板A与第二磁芯盖板B装配后，第一侧边部C1、第三侧边部C3以及第二侧边部C2均对第一磁芯盖板A或第二磁芯盖板B起到支撑作用，两个绕线柱D、E设置有气隙，对第一磁芯盖板A或第二磁芯盖板B不起支撑作用。其中，由于第一侧边部C1、第三侧边部C3以及第二侧边部C2依次相连接，形成一个三面包围、一面开口的结构，因此，第一侧边部C1和第二侧边部C2的端部分别从相对的左右两侧延伸至边柱C开口处，第一侧边部C1和第二侧边部C2分别从相对的左右两侧支撑第一磁芯盖板A或第二磁芯盖板，使得组合后的磁芯结构更加稳固。When the first core cover A and the second core cover B are assembled, the first side portion C1, the third side portion C3, and the second side portion C2 are all aligned with the first core cover A or the second side portion C2. The second core cover B plays a supporting role, and the two winding posts D and E are provided with an air gap and do not support the first core cover A or the second core cover B. Among them, since the first side part C1, the third side part C3 and the second side part C2 are connected in sequence to form a structure surrounded by three sides and open on one side, therefore, the first side part C1 and the second side part are The ends of the portion C2 extend from the opposite left and right sides to the opening of the side column C respectively. The first side portion C1 and the second side portion C2 respectively support the first magnetic core cover A or the third core cover A from the opposite left and right sides. The two magnetic core covers make the combined magnetic core structure more stable.
作为本实施例的一个优选方式，绕线柱横截面长度尺寸较大的方向朝向边柱的开口设置。具体地，两个绕线柱D、E横截面在横向和纵向上均有相互垂直的长度，其中，长度尺寸较大的方向，朝向边柱的开口。如图1所示，两个绕线柱D、E横截面为跑道形，两个绕线柱D、E平行于第一侧边部C1和第二侧边部C2的长度尺寸大于垂直于第三侧边部C3的宽度尺寸。如此设置，可以增加第一侧边部C1（或第二侧边部C2）与第三侧边部C3的尺寸比例，不会使得磁芯结构沿第三侧边部C3较长、沿第一侧边部C1和第二侧边部C2较短，防止磁芯结构整体呈现为狭长结构。相对于狭长架构，如果第一侧边部C1和第二侧边部C2的长度越长，即增加了两侧支撑部的长度，可以进一步增加支撑稳固度。如果第一侧边部C1和第二侧边部C2长度非常短，而第三侧边部C3较长，则主要支撑力仍然在第三侧边部C3上，没有形成有效的两侧支撑的技术效果。通常情况下，第一侧边部C1和第二侧边部C2的长度会根据绕线柱D、E横截面的长度进行适应性设置。As a preferred way of this embodiment, the direction in which the cross-sectional length of the winding column is larger is toward the opening of the side column. Specifically, the cross-sections of the two winding columns D and E have mutually perpendicular lengths in both the transverse and longitudinal directions, wherein the larger length direction is toward the opening of the side column. As shown in Figure 1, the cross-sections of the two winding columns D and E are racetrack-shaped. The lengths of the two winding columns D and E parallel to the first side part C1 and the second side part C2 are larger than those perpendicular to the first side part C1 and the second side part C2. The width dimensions of the three side edges C3. With this arrangement, the size ratio of the first side portion C1 (or the second side portion C2) to the third side portion C3 can be increased without making the core structure longer along the third side portion C3 and longer along the first side portion C3. The side portion C1 and the second side portion C2 are shorter to prevent the entire magnetic core structure from becoming a long and narrow structure. Compared with the long and narrow structure, if the length of the first side part C1 and the second side part C2 is longer, that is, the length of the support parts on both sides is increased, and the support stability can be further increased. If the lengths of the first side part C1 and the second side part C2 are very short, and the third side part C3 is longer, the main supporting force is still on the third side part C3, and no effective two-side support is formed. technical effects. Normally, the lengths of the first side portion C1 and the second side portion C2 are adaptively set according to the lengths of the cross-sections of the winding posts D and E.
作为本实施例的另一个优选方式，所述至少两个绕线柱D、E朝向边柱C开口的端部不超出第一侧边部C1位于边柱开口处端部与第二侧边部C2位于边柱开口处端部之间的连线。即第一侧边部C1和第二侧边部C2朝向边柱开口方向的端部一直向边柱开口方向延伸，并超出两个绕线柱D、E朝向边柱C开口的端部。如此，两个绕线柱D、E完全位于第一侧边部C1、第三侧边部C3以及第二侧边部C2依次连接形成的三面包围的区域内，磁芯结构的整体重心完全位于第一侧边部C1和第二侧边部C2之间。第一侧边部C1和第二侧边部C2分别从相对的左右两侧支撑第一磁芯盖板A或第二磁芯盖板，使得组合后的磁芯结构更加稳固。As another preferred way of this embodiment, the ends of the at least two winding posts D and E that open toward the side post C do not exceed the first side portion C1 between the end of the side post opening and the second side portion. C2 is located on the line between the ends of the side post openings. That is, the end portions of the first side portion C1 and the second side portion C2 that face the direction of the opening of the side pillar extend all the way toward the direction of the opening of the side pillar, and exceed the ends of the two winding posts D and E that face the opening of the side pillar C. In this way, the two winding columns D and E are completely located in the area surrounded by three sides formed by the first side part C1, the third side part C3 and the second side part C2 being connected in sequence, and the overall center of gravity of the magnetic core structure is completely located in between the first side part C1 and the second side part C2. The first side portion C1 and the second side portion C2 respectively support the first core cover A or the second core cover from opposite left and right sides, making the combined core structure more stable.
作为本实施例的另一个优选方式，边柱内侧为连续的面，未设置凸出部。即第一侧边部C1、第三侧边部C3以及第二侧边部C2依次连接后，其内侧为连续的面，这样不会影响绕组走线。如果边柱内侧有凸起，则在绕组走线时需要避让该凸起，走线不便。As another preferred way of this embodiment, the inner side of the side pillar is a continuous surface without protruding parts. That is, after the first side part C1, the third side part C3 and the second side part C2 are connected in sequence, the inner side thereof is a continuous surface, which will not affect the winding wiring. If there is a bulge on the inside of the side pillar, you need to avoid the bulge when routing the windings, which will make routing inconvenient.
作为本实施例的另一个优选方式，所述第一侧边部C1、第三侧边部C3以及第二侧边部C2在长度方向沿直线延伸或弯曲延伸。所述第一侧边部C1、第三侧边部C3以及第二侧边部C2在长度方向可以为直条形结构，也可以为弯曲延伸的结构，还可以为弧形结构。As another preferred embodiment of this embodiment, the first side portion C1, the third side portion C3, and the second side portion C2 extend in a straight line or in a curve in the length direction. The first side portion C1, the third side portion C3, and the second side portion C2 may have a straight strip structure, a curved and extended structure, or an arc-shaped structure in the length direction.
作为本实施例一种可选的实施方式，绕线柱D、E的横截面形状可为方形、圆形、椭圆形或跑道形中的一种或几种，图1所示绕线柱D、E的横截面形状均为跑道形，也可根据实际需求任意组合，如绕线柱D的截面形状为跑道形，绕线柱E的截面形状为圆形。绕线柱D、E的横截面积大小可根据实际需求设置，绕线柱D的截面积与绕线柱E的截面积可以相等，也可以不相等。如果绕线柱D横截面为方形或圆形，而绕线柱E的横截面为椭圆形或跑道形，则绕线柱E横截面尺寸较大的长度方向朝向边柱的开口设置。As an optional implementation of this embodiment, the cross-sectional shape of the winding posts D and E can be one or more of square, circular, oval or racetrack shape. The winding post D is shown in Figure 1 The cross-sectional shapes of E and E are all racetrack-shaped, and can be combined in any combination according to actual needs.

在图5所示实施例中，W1与W2分别为围绕绕线柱D和E的绕组，绕组W1和W2可以为PCB、漆包线、三层绝缘线、铜条或其他形式的绕组。In the embodiment shown in Figure 5, W1 and W2 are windings surrounding the winding columns D and E respectively. The windings W1 and W2 can be PCB, enameled wire, three-layer insulated wire, copper strip or other forms of winding.
在图5所示实施例中，绕线柱D与绕组W1构成一个电感器，绕线柱E与绕组W2则构成了另一个电感器。根据实际需求，绕组W1与W2可以单独使用，也可将W1与W2进行串联或并联使用。绕组W1中的电流在绕线柱D上产生的磁通为Φ1，磁通Φ1具有第一方向，绕组W2中的电流在绕线柱E上产生的磁通为Φ2，磁通Φ2具有第二方向，上述的第一方向与第二方向为相反方向，从而可以减小第一磁芯盖板A和第二磁芯盖板B中的磁通，降低第一磁芯盖板A和第二磁芯盖板B的厚度。如图5所示，流过绕组W1的电流I1的方向为顺时钟，在绕线柱D中产生的磁通Φ1的方向为向下，流过绕组W2的电流I2的方向为逆时钟，在绕线柱E中产生的磁通Φ2的方向为向上，磁通Φ1的方向与磁通Φ2的方向相反。简言之，可以通过设置流经相邻绕线柱上绕组的电流方向以使得相邻绕线柱上的磁通方向相反。或者设置相邻绕线柱上绕组的绕线方向以使得相邻绕线柱上的磁通方向相反。In the embodiment shown in FIG. 5 , the winding post D and the winding W1 form one inductor, and the winding post E and the winding W2 form another inductor. According to actual needs, windings W1 and W2 can be used alone, or W1 and W2 can be used in series or parallel.

The magnetic flux generated by the current in the winding W2 on the winding column E is Φ2, and the magnetic flux Φ2 has the second direction. direction, the above-mentioned first direction and the second direction are opposite directions, thereby reducing the magnetic flux in the first core cover plate A and the second core cover plate B, and reducing the magnetic flux in the first core cover plate A and the second core cover plate B. Thickness of core cover plate B. As shown in Figure 5, the direction of the current I1 flowing through the winding W1 is clockwise, the direction of the magnetic flux Φ1 generated in the winding column D is downward, and the direction of the current I2 flowing through the winding W2 is counterclockwise. The direction of the magnetic flux Φ2 generated in the winding column E is upward, and the direction of the magnetic flux Φ1 is opposite to the direction of the magnetic flux Φ2.

In this embodiment, the winding W1 and the winding W2 are connected in series, and the current outflow end of the winding W1 is connected to the current inflow end of the winding W2. In the same way as the embodiment shown in Figure 5, the direction of the magnetic flux Φ1 generated by the current I1 in the winding W1 on the winding column D is downward, and the direction of the magnetic flux Φ2 generated by the current I1 in the winding W2 on the winding column E is downward. The direction is upward, and the direction of magnetic flux Φ1 is opposite to the direction of magnetic flux Φ2. Connecting windings W1 and W2 in series can form an inductor with a larger inductance.

There are two windings on the winding column D, including the winding W1 and the winding W3. The winding column D, the winding W1 and the winding W3 can form a transformer, in which the winding W1 is the primary winding and the W3 winding is the secondary winding.

Same as the above embodiment, the magnetic fluxes Φ1 and Φ2 generated by the currents I1 and I2 on the winding column are in opposite directions.
