Wire coil device and glue pouring process thereof

Abstract

The invention provides a wire coil device and a glue pouring process thereof. The wire coil device comprises a coil tray, an excitation wire, an insulating plate, a ferrite assembly and a heat dissipation plate, wherein the excitation wire is contained in a wire groove of the coil tray, a plurality of limiting protrusions are further arranged at the bottom of the coil tray, the insulating plate is stacked above the excitation wire, the limiting protrusions support the insulating plate, a first glue pouring space is formed between the insulating plate and the coil tray, the ferrite assembly is stacked above the insulating plate, the heat dissipation plate is installed at the opening of the coil tray, and a second glue pouring space is formed between the heat dissipation plate and the ferrite assembly. According to the invention, a glue filling runner is specially designed, so that the heat-conducting glue can flow conveniently during glue filling, and the whole internal cavity can be quickly filled with the heat-conducting glue. Through the integrated design of the ferrite assembly, the assembly is convenient, and the magnetic loss of the ferrite is reduced. The limiting protrusions are additionally arranged on the coil tray, so that the gap between the insulating plate and the coil tray is increased, and a glue pouring channel can be formed easily.

Description

technical field [0001] The invention relates to the technical field of high-power wireless charging, in particular to a wire reel device and a glue filling process thereof. Background technique [0002] With the development of science and technology and the status quo of dealing with environmental problems, new energy vehicles have developed rapidly in recent years. Electric vehicles in new energy vehicles use high-energy-density battery packs as power sources, and use clean energy to achieve electrical energy conversion. At present, the battery packs of electric vehicles mainly rely on charging piles and are charged through wired methods. However, the convenience and versatility of wired charging methods are limited to a certain extent. Therefore, existing electric vehicles can be charged using wireless charging. [0003] In the existing wireless charging system for electric vehicles, there are the following problems in the reel device: 1) The gaps between the parts are v...

AI Technical Summary

Problems solved by technology

[0003] In the existing wireless charging system for electric vehicles, there are the following problems in the wire reel device: 1) The gap between the parts is very small, so that the heat-conducting glue does not flow properly when the glue is poured, and the parts cannot be completely submerged

2) It is inconvenient to assemble with a large number of ferrites, and it is easy to misplace without a limit slot

3) The size of the insulating board is too large, and it is easy to warp and deform during processing
