[0020] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1-5 , the present utility model provides a technical solution: a patch inductor with a new structure used in energy storage devices, including a magnetic core 1, a coil 2 wound around the magnetic core 1, and a retaining spring 9. It further includes a lower skeleton 3 and an upper skeleton 4, which are formed by splicing the lower skeleton 3 and the upper skeleton 4. The magnetic core 1 is arranged inside the upper skeleton 4 and the lower skeleton 3. Support skeletons 10 that can be spliced are fixedly arranged on the side walls of the lower skeleton 3 and the upper skeleton 4. The retaining spring 9 is arranged on the support skeleton 10. On both sides of the end of the retaining spring 9 far from the magnetic core 1, small buckles 11 are symmetrically fixed. The small buckles 11 are engaged with the upper skeleton 4 and the lower skeleton 3. On the side wall of the retaining spring 9 far from the large buckles 11, a plurality of small buckles 12 are symmetrically fixed. The small buckles 12 are engaged with the upper skeleton 4 and the lower skeleton 3.

[0022] Specifically, one end of the lower skeleton 3 that fits with the upper skeleton 4 is fixedly provided with an insertion block 8, and a slot 7 for inserting the insertion block 8 is opened at one end of the upper skeleton 4 that fits with the lower skeleton 3. The insertion block 8 and the slot 7 are in interference fit to improve the stability of the splicing of the lower skeleton 3 and the upper skeleton 4.

[0023] Specifically, positioning blocks 6 are symmetrically and fixedly arranged at both ends of the magnetic core 1. Positioning grooves 5 for the positioning blocks 6 to be inserted into are opened on the inner walls of the upper skeleton 4 and the lower skeleton 3. The positioning blocks 6 are square blocks and are in close fit with the positioning grooves 5 to improve the stability of the installation of the magnetic core 1 inside the upper skeleton 4 and the lower skeleton 3 and prevent the magnetic core 1 from rotating.

[0024] Specifically, the large buckle 11 includes a large vertical plate 111 and a large horizontal plate 112. Large vertical plate grooves 13 for the large vertical plate 111 to slide into are opened on the inner walls of the upper skeleton 4 and the lower skeleton 3 at the end far from the magnetic core 1. The large vertical plate 111 is in close fit with the inner wall of the large vertical plate groove 13. A large horizontal plate groove 14 is opened on one side of the large vertical plate groove 13 far from the support skeleton 10. The large horizontal plate 112 is tightly engaged with the large horizontal plate groove 14. Through the close fit of the large vertical plate 111 and the large vertical plate groove 13 and the engagement of the large horizontal plate 112 and the large horizontal plate groove 14, the stability of the retaining spring 9 is improved. The large buckle 11 and the retaining spring 9 are made of the same material and have elasticity.

[0025] Specifically, the small buckle 12 includes a small vertical plate 121 and a small horizontal plate 122. On the inner walls of the upper skeleton 4 and the lower skeleton 3 away from the large vertical plate groove 14, there are small vertical plate grooves 15 for the small vertical plate 121 to slide into. The small vertical plate 121 fits against the inner wall of the small vertical plate groove 15. On the side of the small vertical plate groove 15 away from the support skeleton 10, there is a small horizontal plate groove 16, and the small horizontal plate 122 is tightly engaged with the small horizontal plate groove 16. Through the fitting of multiple small vertical plates 121 and the small vertical plate grooves 15, and the engagement of multiple small horizontal plates 122 and the small horizontal plate grooves 16, the stability of the retaining spring 9 is ensured. The small buckle 12 is made of the same material as the retaining spring 9 and has elasticity.

[0026] Specifically, the retaining spring 9 fits against the support skeleton 10. When installing the retaining spring 9, the large buckle 11 and the small buckle 12 are respectively slid into the large vertical plate groove 13 and the small vertical plate groove 15. The large horizontal plate 112 abuts against the inner wall of the large vertical plate groove 13 and slides down in the large vertical plate groove 13, and the small horizontal plate 122 abuts against the inner wall of the small vertical plate groove 15 and slides down in the small vertical plate groove 15. Both the large vertical plate 111 and the small vertical plate 121 undergo slight elastic deformation until the retaining spring 9 fits against the support skeleton 10. At this time, the large horizontal plate 112 just snaps into the large horizontal plate groove 14 and fits against the inner wall of the large horizontal plate groove 14. The large vertical plate 111 loses the acting force between the large horizontal plate 112 and the inner wall of the large vertical plate groove 13 and recovers its deformation to fit against the inner wall of the large vertical plate groove 13. Similarly, the small horizontal plate 122 snaps into the small horizontal plate groove 16 and fits against the inner wall of the small horizontal plate groove 16, and the small vertical plate 121 fits against the inner wall of the pin vertical plate groove 15, thus ensuring the stability of the installation of the retaining spring 9.

[0027] A specific application example of this embodiment is:

[0028] When the device is in use and installing the retaining spring 9, the large buckle 11 and the small buckle 12 are respectively slid into the large vertical plate groove 13 and the small vertical plate groove 15. The large horizontal plate 112 abuts against the inner wall of the large vertical plate groove 13 and slides down in the large vertical plate groove 13, and the small horizontal plate 122 abuts against the inner wall of the small vertical plate groove 15 and slides down in the small vertical plate groove 15. Both the large vertical plate 111 and the small vertical plate 121 undergo slight elastic deformation until the retaining spring 9 fits against the support skeleton 10. At this time, the large horizontal plate 112 just snaps into the large horizontal plate groove 14 and fits against the inner wall of the large horizontal plate groove 14. The large vertical plate 111 loses the acting force between the large horizontal plate 112 and the inner wall of the large vertical plate groove 13 and recovers its deformation to fit against the inner wall of the large vertical plate groove 13. Similarly, the small horizontal plate 122 snaps into the small horizontal plate groove 16 and fits against the inner wall of the small horizontal plate groove 16, and the small vertical plate 121 fits against the inner wall of the pin vertical plate groove 15, thus ensuring the stability of the installation of the retaining spring 9. Then it is fixed with tape (this is the prior art). When welding the retaining spring 9 to the circuit board of the client, the retaining spring 9 will not warp and cause poor flat adhesion, resulting in unstable operation of the inductor.
