Description

Technical Field

[0001] This invention relates to the technical field of wireless charging structures, specifically to a Litz wire winding structure for a wireless charging box. Background Technology

[0002] The existing wireless charging box ground vehicle end structure requires complex wiring during actual assembly, and especially at the end of the cable, there is a winding conflict with the already wound Litz coil. Therefore, how to reliably and reasonably arrange the Litz coil has become an urgent technical problem to be solved for wireless charging boxes. Summary of the Invention

[0003] To address the aforementioned issues, this invention provides a Litz coil winding structure for a wireless charging box, which makes the winding of the Litz coil reliable and convenient, thereby improving the efficiency of product assembly.

[0004] A Litz wire winding structure for a wireless charging case, characterized in that it comprises:

[0005] The cover plate includes an upper cover plate and four side plates. The upper cover plate is provided with corresponding side plates on its four sides, and adjacent side plates are connected to form an overall outer contour edge with height.

[0006] And Litz coils;

[0007] The upper cover plate has a first wire inlet and a second wire outlet arranged at intervals on one corner side. The lower surface area of ​​the upper cover plate has several spiral downward protrusion rings arranged in a manner that forms a cavity for mounting the Litz coil between adjacent spiral downward protrusion rings. The spiral downward protrusion rings are arranged from the outside to the inside. The end of the innermost spiral downward protrusion ring is provided with a guide downward protrusion. The guide downward protrusion faces the second wire outlet located at the corner. The guide downward protrusion is lower than the overall lower surface of the spiral downward protrusion ring. The lower surface of the corresponding position of the spiral downward protrusion ring between the guide downward protrusion and the second wire outlet is provided with a first downward protrusion guide member. The first downward protrusion guide members are combined to guide the Litz coil. The first wire inlet is connected to the inlet of the outermost spiral downward protrusion ring through the guide downward protrusion.

[0008] The Litz coil is wound around a first wire inlet, a guide convex ring, a spiral convex ring arranged from the outside to the inside, a guide convex ring, a first convex guide member, and a second wire outlet. The Litz coil is reliably embedded between adjacent spiral convex rings.

[0009] Its further features are:

[0010] The relative inlet and outlet positions of the first line inlet and the second line outlet are interchanged, and the spiral lower convex ring is arranged from the inside to the outside.

[0011] The lower surface of several spiral convex rings is provided with several lower protrusions at intervals. The equivalent lower plane formed by the lower protrusions is flush with the equivalent lower plane of the first lower convex guide, ensuring that the cover plate is flat and stable after installation.

[0012] The upper cover plate is a square structure as a whole. Each spiral lower convex ring is a square structure with rounded corners. Each spiral lower convex ring includes four sides. Each side includes a center side and two side arcs. The two side arcs of adjacent sides combine to form an overall transition arc. Three overall transition arcs correspond to the spiral lower convex rings at their respective positions. One overall transition arc is a staggered overall transition arc. The output end of each arc of the staggered overall transition arc connects to the center side corresponding to the adjacent inner spiral lower convex ring to form a spiral structure, which makes the overall structure convenient and reliable to arrange.

[0013] The misaligned overall transition arc corresponds to the guide convexity and the second line exit arrangement;

[0014] A cross-shaped downward convex reinforcing rib is provided at the center of the lower surface of the upper cover plate. Auxiliary reinforcing ribs are also provided on the four sides of the cross-shaped downward convex reinforcing rib. Extending oblique reinforcing ribs are provided at the four corners of the upper cover plate corresponding to the cross-shaped downward convex reinforcing rib. Each extending oblique reinforcing rib extends outward from the outermost spiral downward convex ring. A circular arc reinforcing rib is also provided on each extending oblique reinforcing rib to ensure that the entire mechanism is stable and reliable.

[0015] By adopting the above technical solution, the Litz coil is directly embedded in the mounting cavity corresponding to the guide protrusion of the upper cover plate, the spiral protrusion ring arranged from the outside to the inside, the guide protrusion, and the first protrusion guide member. This makes the winding of the Litz coil reliable and convenient, and improves the efficiency of product assembly. Attached Figure Description

Detailed Implementation

[0021] The wireless charging case features a Litz wire winding structure, see [link / details]. Figures 1-3 It includes a cover plate 10 and a Litz coil 20;

[0022] The cover plate 10 includes an upper cover plate 11 and four side plates 12. The upper cover plate 11 is provided with corresponding side plates 12 on its four sides. Adjacent side plates 12 are connected to form an overall outer contour edge with height.

[0023] The upper cover plate 11 has a first wire inlet 13 and a second wire outlet 14 arranged at intervals on one corner side. The lower surface area of ​​the upper cover plate 11 has several spiral lower protrusion rings 15 arranged in a row. The adjacent spiral lower protrusion rings 15 form a cavity for mounting the Litz coil 20. The spiral lower protrusion rings 15 are arranged from the outside to the inside. The end of the innermost spiral lower protrusion ring is provided with a guide protrusion 16. The guide protrusion 16 faces the second wire outlet 14 located at the corner. The guide protrusion 16 is lower than the overall lower surface of the spiral lower protrusion ring 15. The lower surface of the corresponding position of the spiral lower protrusion ring between the guide protrusion 16 and the second wire outlet 14 is provided with a first lower protrusion guide 17. The first lower protrusion guide 17 is used to guide the Litz coil 20. The first wire inlet 13 is connected to the inlet of the outermost spiral lower protrusion ring 15 through the guide protrusion 18.

[0024] The Litz coil 20 is wound around the first wire inlet 13, the guide protrusion 18, the spiral protrusion ring 15 arranged from the outside to the inside, the guide protrusion 16, the first protrusion guide 17, and the second wire outlet 14. The Litz coil 20 is reliably embedded between adjacent spiral protrusion rings 15.

[0025] In practice, the relative entrance and exit positions of the first line entrance 13 and the second line exit 14 can be interchanged, and the spiral lower convex ring 15 is arranged from the inside out.

[0026] In specific implementation, the upper cover plate 11 is a square structure as a whole, and each spiral lower convex ring 15 is a square structure with rounded corners. Each spiral lower convex ring includes four sides, and each side includes a center side 151 and two side arcs. The two side arcs of adjacent sides combine to form an overall transition arc 152. Among them, three overall transition arcs correspond to the spiral lower convex rings at their respective positions. One overall transition arc is a staggered overall transition arc 153. The output end of each arc of the staggered overall transition arc 153 is connected to the center side 151 corresponding to the adjacent inner spiral lower convex ring 15 to form a spiral structure, which makes the overall structure convenient and reliable to arrange.

[0027] The misaligned overall transition arc 153 corresponds to the area position arrangement of the guide convex 16 and the second line outlet 14.

[0028] A cross-shaped reinforcing rib 111 is provided at the center of the lower surface of the upper cover plate 11. Auxiliary reinforcing ribs 112 are provided on the four sides of the cross-shaped reinforcing rib 111. Extending oblique reinforcing ribs 113 are provided at the four corners of the upper cover plate 11 corresponding to the cross-shaped reinforcing rib 111. Each extending oblique reinforcing rib 113 extends outward from the outermost spiral ring 15. A circular arc reinforcing rib 114 is also provided on each extending oblique reinforcing rib 113 to ensure that the entire mechanism is stable and reliable.

[0029] The lower surface of several spiral lower convex rings 15 is provided with several lower protrusions 154 at intervals. The equivalent lower plane formed by the lower protrusions 154 is flush with the equivalent lower plane of the first lower convex guide member 17, ensuring that the cover plate 10 is flat and stable after installation.

[0030] The principle is as follows: The Litz coil is directly embedded in the mounting cavity corresponding to the guide protrusion of the upper cover plate, the spiral protrusion ring arranged from the outside to the inside, the guide protrusion, and the first protrusion guide member. This makes the winding of the Litz coil reliable and convenient, and improves the efficiency of product assembly.
