[0010] All embroidery threads are arranged in a matrix on the surface layer and the bottom layer, including mutually intersecting thread columns and thread rows. A single thread column includes multiple embroidery threads arranged at intervals, and a single thread row includes multiple embroidery threads arranged at intervals. The outer ends of all inner bottom threads in each thread column are connected to the same conductive strip, and all conductive strips are arranged at intervals.

[0013] The inner surface wire, inner bottom wire and outer bottom wire are all commercial conductive silver wires, and the line conductive strips and ball conductive strips are all copper foil or aluminum foil.

[0014] The outer thread is a thermochromic yarn.

[0015] In the single embroidery thread, the endpoints at both ends of the inner surface thread and the endpoints at both ends of the inner bottom thread are connected in a one-to-one correspondence to form an endpoint knot.

[0016] In the single hydrangea, each surface radial line has its two ends arranged with the inner surface line as the symmetry line, and each base radial line has its two ends arranged with the inner base line as the symmetry line.

[0017] In the single hydrangea, the portion between the two ends of each surface radial line spans above the surface layer, and the portion between the two ends of each bottom radial line spans below the bottom layer.

[0018] In the single hydrangea, the bottom surface of the upper spherical shell and the top surface of the lower spherical shell are both circular or quasi-circular surfaces composed of multiple overlapping angles. The overlapping angles in the upper spherical shell are composed of the endpoints of at least two surface radial lines, and the overlapping angles in the lower spherical shell are composed of the endpoints of at least two bottom radial lines.

[0019] The bottom surface of the wire conductive strip is covered with a layer of wire insulating tape, and the portion of the wire insulating tape extending outside the wire conductive strip is bonded to the bottom layer.

[0020] A method for manufacturing the above-mentioned three-dimensional electrothermal and temperature-induced display matrix embroidery fabric, the manufacturing method comprising the following steps:

[0021] Step 1: First, sew the first embroidery thread on the top layer and the bottom layer, then sew the second embroidery thread vertically, etc., until the first thread column is obtained, then sew the second thread column on the top layer and the bottom layer, etc., until all the thread columns are obtained. At this time, the embroidery threads adjacent to each other in the horizontal and vertical directions are separated from each other;

[0022] Step 2: First, sew the first embroidery ball on the inner end of the first embroidery thread in the first thread column, then sew the second embroidery ball vertically, and so on, until the first ball column is obtained. Then, use the same method to sew the second ball column on the second thread column, and so on, until all the ball columns are obtained. At this point, the embroidery balls adjacent to each other in the horizontal and vertical directions are separated from each other;

[0023] Step 3: First, on the bottom layer, connect the outer ends of all inner bottom lines in the first line column to the first line conductive strip, then connect the outer ends of all inner bottom lines in the second line column to the second line conductive strip, and so on, until all line columns are connected to the line conductive strips one by one, and adjacent line conductive strips are separated from each other;

[0024] Step 4: First, on the bottom layer, connect the lower bumps of all lower spherical shells in the first spherical row with the first spherical conductive strip, then connect the lower bumps of all lower spherical shells in the second spherical row with the second spherical conductive strip, and so on, until all spherical rows are connected with spherical conductive strips one by one, and adjacent spherical conductive strips are separated from each other, and any line conductive strips and spherical conductive strips are separated from each other.

[0025] In the first step, when sewing a single thread column, after a certain thread is sewn, the inner top thread and the inner bottom thread start from the end point where the sewing of the thread is finished, first vertically cross the top layer and the bottom layer to sew one end point of the next thread, and then reciprocate along a horizontal straight line until the other end point is completed. Then, starting from the other end point, the inner top thread and the inner bottom thread again vertically cross the top layer and the bottom layer to sew one end point of the next thread, and so on, until the sewing of all the threads in the thread column is completed;

[0026] Then, starting from the end point of the last stitch in the thread column, first cross the surface layer and the bottom layer obliquely to sew one end point of the first embroidery thread in the next thread column, and then interweave back and forth along the horizontal straight line until the other end point is completed. Then, starting from the other end point, the inner surface thread and the inner bottom thread again vertically cross the surface layer and the bottom layer to sew one end point of the next new embroidery thread, ..., until the sewing of all embroidery threads in the next thread column is completed, ..., until the sewing of all embroidery threads in all thread columns is completed. At this time, all the embroidery threads in a single thread column and the vertically spanned inner surface threads and inner bottom threads together constitute a wall structure, and adjacent wall structures are connected in sequence through the obliquely spanned inner surface threads and inner bottom threads.

[0027] Finally, cut off all the vertical and diagonal inner top and bottom threads along the end points of the embroidery thread, and tie a knot at the end point of the embroidery thread to obtain an end point knot to end the first step.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] 1. The present invention provides a three-dimensional electrothermal and temperature-induced screen display matrix embroidery fabric and a manufacturing method thereof, comprising a top layer and a bottom layer stacked up and down, wherein embroidery threads and embroidery balls are arranged in a matrix on the top layer and the bottom layer simultaneously to form a plurality of thread columns, thread rows, sphere columns, and sphere rows, wherein the outer ends of all inner bottom threads in each thread column are connected to the same thread conductive strip, and the lower protrusions of all lower sphere shells in each sphere row are connected to the same sphere conductive strip, wherein the embroidery balls are hollow structures, comprising an upper sphere shell and a lower sphere shell connected up and down, one embroidery thread corresponds to one embroidery ball, and the lower sphere shell contacts the inner bottom thread in the corresponding embroidery thread, and the sphere conductive strip, the lower sphere shell, the thread conductive strip, and the inner bottom thread are arranged in sequence from bottom to top, and at the same time, the outer thread is a heat conductive wire, and the inner surface thread, the inner bottom thread, and the outer bottom thread are all conductive wires, and the sphere conductive strip has a higher conductivity priority than the outer bottom thread. This design has the following advantages:

[0030] First, when this design is used, the spherical conductive strip has a higher conductivity priority than the outer bottom line (current will only follow the shortest path with the least resistance). This gives the spherical conductive strip precedence over the hydrangea itself. Therefore, according to the application requirements, each hydrangea can be precisely energized and heated, and then the hydrangea can heat the area to be heated. Unlike existing technologies that can only heat the entire area, this design has high accuracy and helps improve heating quality. It has a wider range of applications, especially in the field of physical therapy, such as heating and massaging acupuncture points on the human body.

[0031] Secondly, this design can achieve both single-point heating and multi-point heating when applied. Not only can the position of a single point be adjusted, but also when heating multiple points, the positions of multiple points can be adjusted to achieve various heating trajectories and further improve the heating quality.

[0032] Third, when this design is used, after the lower sphere of a hydrangea is energized and heated, the hydrangea can transfer heat to the corresponding upper sphere, causing the upper sphere to heat up and be detected by the heat observation device. This allows the heating status to be observed from the outside of the fabric, and timely feedback can be provided according to application needs, further improving the heating quality.

[0033] Fourthly, in this design, the inner surface wire, inner bottom wire, and outer bottom wire are used to generate heat when powered on. These conductive wires are highly flexible and their resistance is not affected by bending. This feature can expand their application range, such as heating fabrics attached to the human body surface. Conventional flexible heating devices will basically change their resistance due to bending, affecting the final heating performance.

[0034] Therefore, the present invention not only has high heating accuracy, which is beneficial to heating quality, but also has high adjustability and a wide range of applications.

[0035] 2. In the present invention, a three-dimensional electrothermal and thermochromic display matrix embroidery fabric and its production method, the outer thread is a thermochromic yarn. This yarn changes color when heated, and can even produce a gradient color effect. The color change of the upper spherical shell can intuitively reflect the heating status of the corresponding lower spherical shell, providing timely heating feedback, thereby improving heating accuracy and heating quality. In addition, by adjusting the position and number of the heated lower spherical shells, the corresponding upper spherical shells can produce trajectories of different colors and shapes, forming a variety of patterns, texts, or letters with different visual effects, thereby producing a personalized display effect, with strong aesthetics, and very suitable for trendy accessories. Therefore, the present invention not only can accurately heat, but also can produce a variety of personalized displays with strong aesthetics, suitable for the needs of smart homes, smart wearables, and personalized products.

[0036] 3. In the three-dimensional electrothermal and temperature-induced display matrix embroidery fabric and its manufacturing method of the present invention, the inner thread, inner bobbin thread, and outer bobbin thread are all commercial conductive silver threads, and the line conductive strips and ball conductive strips are all copper foil or aluminum foil. The advantages of this design include:

[0037] First, the resistance of copper foil or aluminum foil is generally only a few ohms, while the resistance of commercial conductive silver wire is in the single digit ohms, which is much greater than that of copper foil or aluminum foil. Therefore, it can meet the requirement that the conductive strip of the ball has a higher conductivity priority than the outer bottom line, which is conducive to achieving precise heating of the hydrangea body.

[0038] Secondly, copper foil or aluminum foil are common conductive materials with low prices, and commercial conductive silver wire is also cheap. It is a silver-plated wire with a polyester base. Silver plating not only has low resistance, but silver itself has a sterilization effect, making it very suitable for making wearable products. At the same time, 100g of 210D conductive silver wire costs only about 200 yuan, and purchasing in bulk can further reduce the price, so the cost is very low.

[0039] Therefore, the raw materials of the present invention are not only easy to obtain, but also relatively low in price, thus having a cost advantage.

[0040] 4. In the present invention, a three-dimensional electrothermal and thermochromic display matrix embroidery fabric and its manufacturing method, when manufacturing the three-dimensional electrothermal and thermochromic display matrix embroidery fabric, first sew the first thread column, the second thread column, ..., on the surface layer and the bottom layer one by one until all the thread columns are obtained, then start from the first embroidery thread in the first thread column, sew the embroidery balls one by one at the inner end or near the inner end of the embroidery thread to obtain the first ball column, then use the same method to obtain all the ball columns, and then connect the outer ends of all the inner bottom threads in each thread column to the wire guide wires one by one. The conductive strips are connected one by one to the upper conductive strips, and then the lower bumps of all lower spherical shells in each spherical row are connected one by one to the spherical conductive strips, until all spherical rows are connected one by one to the spherical conductive strips. This production method not only has clear operational steps and strong continuity, allowing for the smooth production of the three-dimensional electrothermal and temperature-induced display matrix embroidery fabric, but also has low operational difficulty, low requirements for production equipment and craftsmanship, and can easily reduce labor and equipment costs, thereby helping to reduce the overall cost of the product. Therefore, the present invention is not only easy to implement but also low in cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0090] Example 2:

[0094] Example 3:

[0095] The basic content is the same as Example 1, except that:

[0096] A method for manufacturing the above-mentioned three-dimensional electrothermal and temperature-induced display matrix embroidery fabric, the manufacturing method comprising the following steps:

[0097] Step 1: If Figure 3 — Figure 6 As shown, the first embroidery thread 3 is sewn on the surface layer 1 and the bottom layer 2, and then the second embroidery thread 3 is sewn vertically, ..., until the first thread column 5 is obtained, and then the second thread column 5 is sewn on the surface layer 1 and the bottom layer 2, ..., until all the thread columns 5 are obtained. At this time, the embroidery threads 3 adjacent in the horizontal and vertical directions are separated from each other;

[0098] Step 2: If Figure 9 — Figure 11 As shown, first sew the first embroidery ball 4 to the inner end of the first embroidery thread 3 in the first thread column 5, then sew the second embroidery ball 4 vertically, ..., until the first ball column 7 is obtained, and then use the same method to sew the second ball column 7 on the second thread column 5, ..., until all the ball columns 7 are obtained. At this time, the embroidery balls 4 adjacent to each other in the horizontal and vertical directions are separated from each other;

[0099] Step 3: If Figure 1 、 Figure 2 As shown, first, on the bottom layer 2, the outer ends of all inner bottom lines 32 in the first line column 5 are connected to the first line conductive strip 6, then the outer ends of all inner bottom lines 32 in the second line column 5 are connected to the second line conductive strip 6, and so on, until all line columns 5 are connected to the line conductive strip 6 one by one, and adjacent line conductive strips 6 are arranged separately from each other;

[0100] Step 4: If Figure 12As shown, first on the bottom layer 2, the lower bumps of all the lower ball shells 47 in the first ball row 71 are connected to the first ball conductive strip 8, and then the lower bumps of all the lower ball shells 47 in the second ball row 71 are connected to the second ball conductive strip 8, ..., until all the ball rows 71 are connected to the ball conductive strips 8 one by one, and adjacent ball conductive strips 8 are separated from each other, and any line conductive strips 6 and ball conductive strips 8 are separated from each other.

[0101] Example 4:

[0102] The basic content is the same as Example 3, except that:

[0103] like Figure 13 、 Figure 14 As shown, in the first step, when sewing a single thread column 5, after a certain embroidery thread 3 is sewn, the inner surface thread 31 and the inner bottom thread 32 start from the end point where the sewing of the embroidery thread 3 is finished, first vertically cross the surface layer 1 and the bottom layer 2 to sew one end point of the next embroidery thread 3, and then reciprocate along the horizontal straight line in sequence until the other end point is completed, and then starting from the other end point, the inner surface thread 31 and the inner bottom thread 32 again vertically cross the surface layer 1 and the bottom layer 2 to sew one end point of the next new embroidery thread 3, ..., until the sewing of all the embroidery threads 3 in the thread column 5 is completed;

[0104] like Figure 15 、 Figure 16 As described, then, starting from the last endpoint of the thread column 5 where sewing is completed, first cross the surface layer 1 and the bottom layer 2 in the oblique direction to sew one endpoint of the first embroidery thread 3 in the next thread column 5, and then reciprocate along the horizontal straight line until the other endpoint is completed, and then starting from the other endpoint, the inner surface thread 31 and the inner bottom thread 32 again cross the surface layer 1 and the bottom layer 2 vertically to sew one endpoint of the next new embroidery thread 3, ..., until the sewing of all the embroidery threads 3 in the next thread column 5 is completed, ..., until the sewing of all the embroidery threads 3 in all thread columns 5 is completed. At this time, all the embroidery threads 3 in the single thread column 5 and the vertically spanning inner surface thread 31 and inner bottom thread 32 together constitute a wall structure 9, and adjacent wall structures 9 are connected in sequence through the obliquely spanning inner surface thread 31 and inner bottom thread 32;

[0105] Finally, all vertical and oblique inner surface threads 31 and inner bottom threads 32 are cut off along the endpoints of the embroidery thread 3, and knots are tied at the endpoints of the embroidery thread 3 to obtain endpoint knots 34 to end the first step.

[0106] Example 5:

[0107] The basic content is the same as Example 1, except that:

[0108] See Figure 17 , the thick black line with an arrow in the figure represents the direction of current flow. It can be seen from the figure that the external current is electrically connected to the inner bottom line 32 through the conductive strip 6, and then the inner bottom line 32 transmits the current to the lower ball shell 47 (i.e., the first hydrangea body 4) in contact with it, and then the lower ball shell 47 transmits the current to the ball conductive strip 8. At this time, since the conductive priority of the ball conductive strip 8 is greater than that of the outer bottom line 42, the current on the ball conductive strip 8 will only be transmitted outward along the ball conductive strip 8, and will not be transmitted to the lower ball shells 47 in the remaining hydrangea bodies 4 (all composed of the outer bottom line 42) until it is connected to the external power supply again, thereby forming a circuit loop. In this circuit loop, only the first hydrangea body 4 is turned on, and the remaining hydrangea bodies 4 are not turned on, thereby realizing point-to-point control that is accurate to the point. By analogy, it is possible to achieve precise control of the remaining points and to simultaneously control different points to form a trajectory.

[0109] In addition, whether it is a single point of power-on heating or a track composed of multiple points of power-on heating, it will be fed back through the corresponding upper ball shell 45. This feedback can be monitored by a heat detection device to timely feedback the circuit conduction status, or the upper ball shell 45 can be preferably made of thermochromic yarn. At this time, according to the color change of the upper ball shell 45, its power-on heating status can be intuitively reflected. It is not only convenient but also beautiful, and can be used for various wearable decorations.

[0110] Example 6:

[0111] The basic content is the same as Example 5, except that:

[0112] See Figure 18 The figure shows the simultaneous point-to-point control of seven hydrangea balls 4, so that these seven balls form a W-shaped trajectory, as shown in the figure:

[0113] The dark red hydrangea body 4 corresponds to circuit No. 1, the bright red hydrangea body 4 corresponds to circuit No. 2, the khaki hydrangea body 4 corresponds to circuit No. 3, the light yellow hydrangea body 4 corresponds to circuit No. 4, the light green hydrangea body 4 corresponds to circuit No. 5, the dark green hydrangea body 4 corresponds to circuit No. 6, and the light blue hydrangea body 4 corresponds to circuit No. 7. The circuits where these seven balls are located are separated from each other. Therefore, once they are turned on at the same time, they will be energized and heated at the same time, forming a trajectory. Similarly, by energizing and heating the remaining point-to-point hydrangea bodies 4, a variety of patterns, shapes, and colors can be obtained.

[0114] Example 7:

[0115] The basic content is the same as Example 1, except that:

[0116] like Figure 19As shown, the upper spherical shell 45 and the lower spherical shell 47 respectively include 16 overlapping angles 48, and the interval between adjacent overlapping angles 48 is 22.5 degrees, and each overlapping angle 48 is composed of the endpoints of three surface radial lines 44 or the endpoints of three bottom radial lines 46, wherein the directions of the surface radial lines 44 and the bottom radial lines 46 include both the diameter direction and the quasi-diameter direction.

[0117] The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiment. Any equivalent modifications or changes made by ordinary technicians in this field based on the contents disclosed in the present invention should be included in the protection scope recorded in the claims.
