[0002] The transformer contains primary windings and secondary windings. When the application scenario or application environment of the transformer changes, the number of turns of the primary windings and secondary windings will change. In the prior art, the area used for primary windings and secondary windings is usually fixed. This means that when the number of turns of the primary windings or secondary windings needs to be changed, especially when the number of turns of the windings needs to be increased, the original winding area cannot meet the number of turns required. At this time, the coils need to be wound in overlapping manner. The overlapping winding method may cause the inductance value to decrease, thereby reducing the efficiency of the transformer. In addition, overlapping coils will also cause mutual interference, thereby affecting the performance and stability of the transformer.

[0009] Furthermore, the slider is a rectangular parallelepiped structure.

[0010] Furthermore, when the driving shaft drives the sliding block to extend into the positioning hole, the position of the adjusting plate relative to the winding post is fixed.

[0011] Furthermore, the side of the slide groove is a convex structure, and the distance between the coil and the winding column in the winding area is greater than 0.

Example 1

[0028] like Figure 1-Figure 4 As shown, a transformer winding structure proposed in the present application includes a winding post 21, and two adjustment plates 11 nested on both sides of the winding post 21, and a winding area 22 is formed between the relatively distant ends of the two adjustment plates 11 and the end of the winding post 21; a slider 12 is provided on the side of the adjustment plate 11 close to the winding post 21, and a slide groove 23 adapted to the slider 12 is provided in the winding post 21, and the slider 12 can slide along the slide groove 23; the extension direction of the slide groove 23 is parallel to the axial center line of the winding post 21.

[0029] In the present application, the slider 12 can move along the slide groove 23, and at the same time, the slider 12 drives the position of the adjustment plate 11 in the winding post 21 to change; the two adjustment plates 11 are respectively nested on the winding post 21, and the area between the adjustment plate 11 and the end of the winding post 21 forms the winding area 22; when the application scenario of the transformer changes, the position of the adjustment plate 11 in the winding post 21 can be changed through the mutual cooperation of the slider 12 in the adjustment plate 11 and the slide groove 23 in the winding post 21, thereby redefining the space size of the winding area 22, ensuring that the space of the winding area 22 is large enough in different application scenarios of the transformer, thereby ensuring single-layer winding in the winding area 22, and improving the performance stability of the transformer. Example 2

[0030] like Figure 1 As shown, a transformer winding structure proposed in the present application includes a winding post 21, and two adjustment plates 11 nested on both sides of the winding post 21, and a winding area 22 is formed between the relatively distant ends of the two adjustment plates 11 and the end of the winding post 21; a slider 12 is provided on the side of the adjustment plate 11 close to the winding post 21, and a slide groove 23 adapted to the slider 12 is provided in the winding post 21, and the slider 12 can slide along the slide groove 23; the extension direction of the slide groove 23 is parallel to the axial center line of the winding post 21.

[0031] A plurality of positioning holes 24 are provided at the bottom of the slide groove 23 of the present application. The positioning holes 24 are distributed along the extension direction of the slide groove 23 , and the positioning holes 24 are adapted to the slider 12 ; the slider 12 is connected to the driving shaft 13 , and the driving shaft 13 can drive the slider 12 to extend into or out of the positioning holes 24 .

[0032] The extending direction of the slide slot 23 is parallel to the axis of the winding rod 21. At the same time, there are multiple positioning holes 24, which are evenly distributed along the extending direction of the slide slot 23. The driving shaft 13 drives the slider 12 to move toward or away from the positioning hole 24. When the slider 12 moves along the slide slot 23 to the preset position, that is, above the preset position positioning hole 24, the driving shaft 13 drives the slider 12 to move toward the positioning hole 24, so that the slider 12 is inserted into the positioning hole 24 to achieve the positioning of the adjustment plate 11. When the position of the adjustment plate 11 needs to be changed, the driving shaft 13 drives the slider 12 to be pulled out of the positioning hole 24. At this time, the slider 12 is located in the slide slot 23 and can slide along the slide slot 23.

[0033] Further, such as Figure 2-Figure 4As shown, in the present application, the winding column 21 is a cylindrical structure, the adjustment plate 11 is an annular structure, the driving shaft 13 is located in the radial direction of the adjustment plate 11, one end of the driving shaft 13 is located outside the adjustment plate 11, and the other end is provided with a slider 12. The extension direction of the driving shaft 13 coincides with the radial direction of the adjustment plate 11, and the function of the driving shaft 13 is that when the slider 12 needs to slide in the slide groove 23, the driving shaft 13 drives the slider 12 to move out of the positioning hole 24; when the slider 12 needs to be fixed in the slide groove 23, the driving shaft 13 drives the slider 12 to extend into the positioning hole 24, so as to position the adjustment plate 11.

[0034] In the present application, the slider 12 is a rectangular parallelepiped structure; correspondingly, the positioning hole 24 is also a rectangular parallelepiped structure, and the slide groove 23 is also a rectangular parallelepiped structure. The width of the slide groove 23 is the same as the width of the positioning hole 24, that is, the width of the slider 12 needs to be compatible with the width of the slide groove 23 and the width of the positioning hole 24. The width of the slide groove 23 refers to the dimension perpendicular to the extension direction of the slide groove 23.

[0035] When the driving shaft 13 drives the slider 12 to extend into the positioning hole 24, the position of the adjustment plate 11 relative to the winding post 21 is fixed. When the driving shaft 13 drives the slider 12 to move out of the positioning hole 24 and is located in the slide groove 23, the slider 12 can drive the adjustment plate 11 to slide along the slide groove 23 to adjust the position of the adjustment plate 11 and change the space of the winding area 22.

[0036] In the present application, the density of the positioning holes 24 in the slide groove 23 determines the precision of the position adjustment of the adjustment plate 11. The more positioning holes 24 there are, the finer the position adjustment of the adjustment plate 11 will be. However, as the density of the positioning holes 24 increases, the cost of the transformer will also increase. In actual operation, the appropriate position of the positioning holes 24 can be selected according to demand. At the same time, the present application can also set the position of the positioning holes 24 according to the application scenario of the transformer to ensure that the adjustment plate 11 can be fixed at a specific position of the winding column 21 in different application scenarios.

[0037] As a specific embodiment, the side of the slide groove 23 in the present application is a raised structure, and the distance between the coil in the winding area 22 and the winding post 21 is greater than 0. That is to say, the slide groove 23 is arranged on the outside of the winding post 21 and extends along the axis of the winding post 21. The slide groove 23 can be a rectangular parallelepiped structure, whose length direction is parallel to the axis of the winding post 21, and whose width direction is perpendicular to the length direction, and on both sides of the width direction, there are raised side edges relative to the outer peripheral side of the winding post 21, and the slider 12 is located inside the slide groove 23, and the width of the slider 12 is equal to the width of the slide groove 23. Since the side of the slide groove 23 is a structure that is raised relative to the winding post 21, when the adjustment plate 11 is nested on the winding post 21, the adjustment plate 11 and the winding post 21 are isolated by the raised side of the slide groove 23, so that a certain gap is retained between the inner diameter of the adjustment plate 11 and the outer diameter of the winding post 21; the coil in the winding area 22 is wound around the outside of the winding post 21; this gap allows the coil and the winding post 21 to dissipate heat during operation, further improving the operating stability of the transformer.

[0038] As another embodiment, the slide groove 23 in the present application is a recessed structure, and the coil in the winding area 22 is wound on the outside of the winding post 21. That is to say, the slide groove 23 is a recessed groove set on the outside of the winding post 21. The slide groove 23 can be a rectangular parallelepiped structure, whose length direction is parallel to the axis of the winding post 21, and whose width direction is perpendicular to the length direction. The slider 12 is located inside the slide groove 23, and the width of the slider 12 is equal to the width of the slide groove 23. The bottom of the slide groove 23 is located inside the winding post 21, and the top of the slide groove 23 is flush with the outer surface of the winding post 21. When the adjustment plate 11 is nested on the winding post 21, the inner diameter of the adjustment plate 11 abuts against the outer diameter of the winding post 21, and the coil in the winding area 22 is wound on the outside of the winding post 21; during the operation of the transformer, the heat generated by the coil can only be dissipated through the outside of the coil, and the heat in the winding post 21 can be dissipated through the unwound area between the two adjustment plates 11.

[0039] In order to ensure that the adjustment plate 11 can slide smoothly along the slide groove 23, the present application has an even number of slide grooves 23, and the even number of slide grooves 23 are evenly distributed along the outer side of the winding column 21; the slider 12 is set in a one-to-one correspondence with the slide groove 23. Figure 3 As shown, when there are four slide slots 23, the four slide slots 23 are distributed on the outer peripheral side of the winding rod 21 at an angle of 90 degrees to each other. Correspondingly, there are also four sliders 12 in the adjustment plate 11, and they are arranged one by one corresponding to the positions of the slide slots 23.

[0040] In order to simplify the structure, the present application can also set two slide grooves 23, and the two slide grooves 23 are symmetrically distributed along the winding pole 21; the sliders 12 are set one by one corresponding to the slide grooves 23. The two sliders 12 slide from the symmetrical ends respectively, and can drive the adjustment plate 11 to move smoothly.

[0041] The present application also provides a transformer, comprising the transformer winding structure as described above.

[0042] In the present application, the slider 12 can move along the slide groove 23, and at the same time, the slider 12 drives the position of the adjustment plate 11 in the winding post 21 to change; the two adjustment plates 11 are respectively nested on the winding post 21, and the area between the adjustment plate 11 and the end of the winding post 21 forms the winding area 22; when the application scenario of the transformer changes, the position of the adjustment plate 11 in the winding post 21 can be changed through the mutual cooperation of the slider 12 in the adjustment plate 11 and the slide groove 23 in the winding post 21, thereby redefining the space size of the winding area 22, ensuring that the space of the winding area 22 is large enough in different application scenarios of the transformer, thereby ensuring single-layer winding in the winding area 22, and improving the performance stability of the transformer.

[0043] It can be understood that the above embodiments only express the preferred implementation methods of the present application, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present application; it should be pointed out that for ordinary technicians in this field, without departing from the concept of the present application, the above-mentioned technical features can be freely combined, and several deformations and improvements can be made, which all belong to the protection scope of the present application; therefore, all equivalent changes and modifications made to the scope of the claims of the present application should belong to the scope covered by the claims of the present application.
