All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-7, the invention provides a coil for a radio frequency energy harvesting system, comprising: the antenna comprises a base part and an antenna part, wherein the base part is woven by base yarns, and the antenna part is woven by conductive yarns.
Furthermore, the base part and the antenna part are connected by adopting a non-dotted line jacquard technology, and specifically, the two connection modes are provided, wherein one mode is that the conductive yarns of the antenna part independently form a part of tissue and are inlaid with the base part to form an antenna shape; the other is that the conductive yarn of the antenna part and the base yarn of the base part are jointly woven and stacked to form an antenna shape.
A manufacturing method of a coil of a radio frequency energy collecting system comprises the following specific steps:
firstly, preparing raw materials: the first raw material is base yarn, and the second raw material is conductive yarn;
the base yarn is composed of various known natural, synthetic and regenerated fibers, including but not limited to pure or blended yarns of cotton, hemp, silk, wool, terylene, chinlon, acrylon, aramid fiber, viscose, acetate and the like;
the conductive yarn is composed of various yarns containing conductive materials, including but not limited to metal, metal-plated polymer, conductive polymer, polymer containing or covering metal or conductive polymer or nano carbon material, and liquid metal polymer complex;
secondly, preparing the fabric by a weaving method, wherein the fabric consists of a base part woven by raw material I base yarn and an antenna part woven by raw material II conductive yarn, the antenna part is stacked or embedded on the base part, and the antenna part forms various required antenna models;
thirdly, the base part can be made into double-sided fabric, namely, one side of the fabric is separately woven by one base yarn, and the other side is woven by the same or different base yarns, and the antenna structure is formed by adopting a weaving method at the position where the antenna pattern is required to be formed;
fourthly, after the specific pattern is formed, connecting the energy collecting system with the conductive yarns on the fabric, wherein the purpose of the connection is to ensure that the antenna is electrically connected with the system, and the connection mode comprises but is not limited to welding, conductive adhesive bonding and conductive magic tape;
and fifthly, encapsulating the system and the connection area of the system and the fabric antenna by using a coating, wherein the coating can be a mixture of epoxy-based, acrylic-based, polyurethane-based or silicone-based resins.
Furthermore, the weaving method of the antenna part inlaid on the base part is that, on a cross, the yarn guide stops moving after the yarn is laid on the base yarn for the last selected needle, then another yarn guide drives another conductive yarn to continue weaving, and finally the base yarn is driven by the yarn guide to continue weaving, and the process can be repeated for a plurality of times according to the designed conductive yarn pattern; and the splicing mode comprises a winding mode and a tucking mode.
Further, the antenna portion is stacked on the base portion by knitting in such a manner that, in a course, the yarn guide continues to move after the last selected stitch such as the ground yarn is laid on the yarn, and then another yarn guide carries another conductive yarn, and both yarns continue to be knitted at the same time, and the process can be repeated a plurality of times according to the designed conductive yarn pattern.
The first implementation mode comprises the following steps:
as shown in fig. 5, which is an overall schematic view of the antenna, the pattern region may be a single row or a single column of conductive yarn, or may be a region formed by multiple rows or multiple columns of conductive yarn formed by multiple reciprocations of conductive yarn. Fig. 6 shows one of the yarn arrangements. The resulting bond to the antenna and energy harvesting system creates an electrical connection through the conductive adhesive. Meanwhile, the parts of the front surface and the back surface of the connecting area are covered by polyurethane coatings.
The manufacturing process of the fabric antenna comprises the following steps:
raw materials: base yarn: pure cotton yarn 32s/1, conductive yarn: silver-plated nylon yarn.
Equipment: full-automatic computerized flat knitting machine
During weaving, in the base yarn area, the machine head drives the base yarn to weave, and the knitting needle of the conductive yarn does not weave at the moment and stays at the edge of the area. Similarly, in the conductive yarn region, the head drives the conductive yarn to weave, while the knitting needle of the base yarn does not weave and stays at the edge of the region. Thus each course is composed of several loops with different yarns concentrated on the reverse side of the fabric. Because the base yarn and the conductive yarn correspond to different yarn guides during knitting, in order to connect the edge wales of two different areas, the two yarns need to form a connecting structure on the same needle between the areas. The joining of the stitches knitted by the yarns guided by the various yarn guides of a course can be carried out by means of stitches, tucks, plating or double stitches.
The second embodiment:
as shown in fig. 7, which is an overall schematic view of the antenna, the pattern region may be a single row or a single column of conductive yarn, or may be a region formed by multiple rows or multiple columns of conductive yarn formed by multiple reciprocations of conductive yarn. Fig. 7 shows one of the yarn arrangements. The antenna and the energy harvesting system are electrically connected by welding. Meanwhile, the parts of the front surface and the back surface of the connecting area are covered by polyurethane coatings.
The manufacturing process of the fabric antenna comprises the following steps:
raw materials: base yarn: pure cotton yarn 32s/1, conductive yarn: stainless steel yarn KTFB 100/1.
Equipment: double needle bed full-automatic computerized flat knitting machine
During weaving, the base yarn is woven in a needle bed to form one side of the fabric, and the other side is woven by the base yarn of the same or different types and the conductive yarn. The two fabrics are connected by using the base yarns, and finally a fabric is formed. In the base yarn area of one side containing the conductive yarn, the machine head drives the base yarn to weave, and the knitting needle of the conductive yarn does not weave at the moment and stays at the edge of the area. Similarly, in the conductive yarn region, the head drives the conductive yarn to weave, while the knitting needle of the base yarn does not weave and stays at the edge of the region. Thus each course is composed of several loops with different yarns concentrated on the reverse side of the fabric. Because the base yarn and the conductive yarn correspond to different yarn guides during knitting, in order to connect the edge wales of two different areas, the two yarns need to form a connecting structure on the same needle between the areas. The joining of the stitches knitted by the yarns guided by the various yarn guides of a course can be carried out by means of stitches, tucks, plating or double stitches.
