Problems solved by technology

However, after research, it was found that in the above-mentioned patents, an independent electromagnetic induction coil is formed by winding the coil and added to the product body. The electromagnetic induction coil cannot be organically combined with the product, and the product integrity is poor.
In addition, the electromagnetic induction coil and the product body are bonded through processes such as bonding, resulting in poor product flexibility, which cannot meet the flexible requirements of wireless charging products.
[0003] Within the scope of the applicant's search, there have been no literature reports on the use of textile technology to manufacture wireless charging materials and subsequent processing to form flexible materials with good integrity and wireless charging functions

Embodiment 1

[0029] A flexible wireless charging material, the structure of which includes an upper cladding layer, a wireless charging layer, a lower cladding layer, a power cord and a wireless charging control module, and a wireless charging layer is arranged between the upper cladding layer and the lower cladding layer. The wireless charging layer is connected to the wireless charging control module through the power line, such as figure 1 shown. Among them, the wireless charging layer is a warp-knitted structure, the wireless charging transmitting coil is formed as a whole during the knitting process of the warp-knitted structure, and the number of winding turns of the wireless charging coil is 4 turns. In the coil wale direction, a row of charging coils is arranged every two knitting courses, such as figure 2 shown. The wireless charging module adopts the 200W / 48V power supply output high-power wireless charging module XKT901-19 product currently available in the market.

Embodiment 2

[0037] According to the process, the wireless charging layer uses the textile yarn as the braided yarn and the enamelled copper wire as the tuck wire, and adopts the continuous pressure-free warp knitting technology to form a winding number of 4 turns, and forms every 2 turns in the direction of the course. A whole fabric with 1 row of charging coils arranged in wales, its structure is as follows image 3 shown. Other processes are as described in Example 1.

Embodiment 3

[0039] According to the process, the wireless charging layer uses the textile yarn as the weaving yarn and the enamelled copper wire as the tuck wire, and adopts the continuous pressure-free warp knitting technology to form a winding number of 7 turns, and is formed in the course and wale direction of the coil. The overall fabric with a row of charging coils arranged every two wales, its structure is as follows Figure 4 shown. Other processes are as described in Example 1.

Abstract

The invention discloses a flexible wireless charging material and a manufacturing method, belongs to the field of wireless charging technologies and textile processing, and particularly relates to a flexible wireless charging material based on electromagnetic induction. The flexible wireless charging material structurally comprises an upper coating layer, a wireless charging layer, a lower coatinglayer, a power line and a wireless charging control module. The wireless charging layer is arranged between the upper coating layer and the lower coating layer, and the wireless charging layer is connected with the wireless charging control module through the power line. The wireless charging control module adopts a 200W / 48V power supply output high-power wireless charging module XKT901-19 product sold in the market. According to the flexible wireless charging material and the manufacturing method provided by the invention, wireless charging functionalization of decorative materials for indoor home furnishing is realized, and intellectualization, flexibility and convenience of the wireless charging material are also realized. The defects of poor combinability of a wireless charging coil and a charging body and poor flexibility of an existing wireless charging material are overcome.

Description

technical field [0001] The invention relates to the field of wireless charging technology and textile processing, in particular to a flexible wireless charging material based on electromagnetic induction. Background technique [0002] With the rapid development of smart electronic products, flexible wireless charging materials have become a hot research topic today. At present, the manufacture of electromagnetic induction and magnetic coupling resonance wireless charging materials is relatively mature and widely used. They are not only used in charging small power appliances such as mobile phones and computers, but also in the field of car charging. In Chinese patent CN208094247U, the wireless charging coil is placed in the body of the wireless charging computer pad, and after being connected to an external power source, it can wirelessly charge a terminal with a wireless charging function placed on the computer pad body. Chinese patent CN208126350U provides a wireless char...
