[0026] like Figure 1 As shown, the winding mechanism provided by the embodiment of the present invention includes: a skeleton 100, a winding 200 and a plurality of magnetic sheets 300; the winding 200 is wound on the skeleton 100, the skeleton 100 is provided with a plurality of slots 101, and the plurality of slots 101 are arranged at intervals along the axial direction of the winding 200; a magnetic sheet 300 is inserted in each slot 101.

[0027] The skeleton 100 is configured as an integrated structure to avoid the skewness of the split structure assembly due to dimensional tolerance. In addition, the magnetic sheet 300 can be configured as a runway-type magnetic sheet or a segmented magnetic sheet. The magnetic sheet 300 can be directly inserted into the slot 101, which is not only convenient to install but also easy to position. It avoids the technical problem of inaccurate positioning of the magnetic sheet 300 due to the skewness of the skeleton 100 assembly, which is conducive to improving the production consistency of the winding mechanism.

[0028] like Figure 1 and Figure 2As shown, in the embodiment of the present invention, the frame 100 is provided with a limiting portion 102 which is opposite to the slot 101 .

[0029] The limiting portion 102 can be loosely fitted to the magnetic sheet 300 to reduce the looseness of the magnetic sheet 300 in the slot 101. In addition, glue can be applied between the magnetic sheet 300 and the limiting portion 102 to reinforce the magnetic sheet 300.

[0030] Furthermore, the skeleton 100 is provided with a slot 103 extending in a direction parallel to the axis of the winding 200. The wiring harness extending from the winding 200 can be arranged along the slot 103. The slot 103 constrains the wiring harness to improve the neatness of the structure.

[0031] In an optional embodiment, the magnetic sheet 300 is bonded and fixed in the slot 101. On the one hand, the magnetic sheet 300 is loosely fitted in the slot 101 to achieve preliminary positioning. On the other hand, the magnetic sheet 300 is reinforced by bonding to prevent the magnetic sheet 300 from loosening.

[0032] In addition, the transformer provided in the embodiment of the present invention adopts the winding mechanism described in the above embodiment.

[0033] like Figure 1 As shown, the frame 100 is mounted on the base 400 , and the winding 200 extends and is connected to the base 400 , wherein the axis of the frame 100 is parallel to the base 400 , so that the frame 100 can be connected to the base 400 in a horizontal position.

[0034] In this embodiment, the base 400 is connected to a magnetic component 500 , and the magnetic component 500 wraps the frame 100 and the winding 200 .

[0035] In an optional embodiment, the magnetic component 500 may adopt an integrated structure.

[0036] In another embodiment, the magnetic member 500 may include: a first magnet 510 and a second magnet 520 ; the first magnet 510 and the second magnet 520 are disposed opposite to each other and are respectively connected to the base 400 .

[0037] Furthermore, the first magnet 510 has a first core inserted into the skeleton 100, and the second magnet 520 has a second core inserted into the skeleton 100. The first core is in contact with the second core. When the skeleton 100 is configured as an integrated structure, the magnetic component 500 is configured as a split structure, which is more convenient for assembly.

[0038] The charger provided by the embodiment of the present invention is equipped with the transformer described in the above embodiment. The charger has the technical effects of the above winding mechanism and transformer, which will not be described in detail here.
