Description

Technical Field

[0001] The present application relates to the technical field of smart textiles, and in particular to a fabric touch-control device. Background Art

[0002] Fabric touch devices are widely used in the field of smart textiles, and their specific application areas include but are not limited to smart clothing, smart home, smart home textiles, smart car accessories, smart textile toys, etc. The main body of the fabric touch device is usually yarn, fiber, fabric, etc., and the fabric touch device can provide the smart device with single-point pressing position information and / or pressure size information during user operation.

[0003] Some existing fabric touch devices can only recognize the position information of a single-point press, but cannot recognize the pressure size at the same time. Although some can recognize the position information of a single-point press and the pressure size information, they need to set up four or more wires to achieve this goal. The number of wires is an important parameter that affects the performance of touch devices. Reducing the number of wires in fabric touch devices will significantly improve the stability and durability of the product. Especially in special fields such as medical, military, police, and firefighting, fabric touch devices need to have fewer wires to meet the needs of streamlining. Summary of the invention

[0044] This embodiment provides a fabric touch-controlled device.

[0045] Please refer to Figure 1-13 The fabric touch device includes a first conductive layer 100 , a second conductive layer 200 and a third conductive layer 300 .

[0046] Please refer to Figure 1-5The first conductive layer 100 includes a first base layer 110, a first semiconductor 120 and a first good conductor 130. The first semiconductor 120 and the first good conductor 130 are both disposed on the first base layer 110. One end of the first good conductor 130 is connected to the first semiconductor 120, and the other end extends on the first base layer 110. The second conductive layer 200 includes a second base layer 210, a second semiconductor 220 and a second good conductor 230. The second semiconductor 220 and the second good conductor 230 are both disposed on the second base layer 210. One end of the second good conductor 230 is connected to the second semiconductor 220, and the other end extends on the second base layer 210. The first conductive layer 100, the second conductive layer 200 and the third conductive layer 300 are stacked in sequence. The third conductive layer 300 includes a third base layer 310, a third semiconductor 320 and a third good conductor 330. The third semiconductor 320 and the third good conductor 330 are both disposed on the third base layer 310, and the third semiconductor 320 is connected to the third good conductor 330. The fabric touch device can switch between a stressed state under the action of an external force and a non-stressed state without the action of an external force. When the fabric touch device is in a non-stressed state, the first conductive layer 100 is isolated from the second conductive layer 200, and the second conductive layer 200 is isolated from the third conductive layer 300. When the fabric touch device is in a stressed state and the applied force is greater than a first preset value, the first good conductor 130 contacts the second good conductor 230, so that the first semiconductor 120, the first good conductor 130, the second good conductor 230 and the second semiconductor 220 jointly form a first conductive path, and the resistance value of the first conductive path uniquely corresponds to a coordinate group in a plane, and each coordinate group includes a first coordinate value representing a position in a first direction in the plane and a second coordinate value representing a position in a second direction in the plane. When the fabric touch device is in a stressed state and the applied force is greater than a second preset value, the second good conductor 230 contacts the third semiconductor 320, so that the second semiconductor 220, the second good conductor 230, the third semiconductor 320 and the third good conductor 330 together form a second conductive path, and the resistance value of the second conductive path decreases as the applied force increases, so that the continuous change in the magnitude of the applied force is represented by the change in the resistance value.

[0047] On the one hand, when the user presses the fabric touch device, if the pressure applied by the user is greater than the first preset value, the first good conductor 130 can be brought into contact with the second good conductor 230, thereby making the first conductive path conductive, and then the coordinate group information of the user's pressing position can be obtained by measuring the resistance value of the first conductive path, that is, the first coordinate value of the user's pressing position in the first direction and the second coordinate value in the second direction in the plane are obtained. If the pressure applied by the user is greater than the second preset value, the second good conductor 230 can be brought into contact with the third semiconductor 320, thereby making the second conductive path conductive, and then the continuous change of the pressing force can be characterized by measuring the change in the resistance value of the second conductive path. This enables the fabric control device to detect both the user's single-point pressing position information and the user's pressure information. On the other hand, at least three wires need to be connected to the first semiconductor 120, the second semiconductor 220 and the third good conductor 330 in a one-to-one correspondence. The single-point pressing position information can be obtained by measuring the resistance value between the wire connected to the first semiconductor 120 and the wire connected to the second semiconductor 220, and the pressure magnitude information can be obtained by measuring the resistance value between the wire connected to the second semiconductor 220 and the wire connected to the third good conductor 330. That is, it is helpful to reduce the number of wires of the fabric touch device, thereby improving the stability and durability of the fabric touch device.

[0048] Please refer to Figure 1-5 It can be understood that, due to the piezoresistive effect, the greater the pressure, the smaller the resistance of the third semiconductor 320, so that the resistance of the second conductive path is smaller, thereby achieving the purpose of characterizing the continuous change of the pressing force by measuring the change in the resistance value of the second conductive path. Of course, in some embodiments, the realization of this purpose may not rely entirely on the piezoresistive effect, but is achieved by the shape matching of the second expansion part 232 and the third expansion part 333, which will be described in detail later in conjunction with specific embodiments. And considering that as the pressure increases, the contact area between the second conductive layer 200 and the third conductive layer 300 increases, the resistance of the second conductive path will also decrease. In short, under the combined effect of multiple factors, the greater the pressure applied by the user, the smaller the resistance of the second conductive path. Thereby, the change in the pressure applied by the user can be identified in turn through the change in the resistance of the second conductive path.

[0049] Please refer to Figure 1-7In one embodiment, the first good conductor 130 includes a plurality of first extensions 131 and a plurality of first extensions (not shown), one end of the first extension 131 is connected to the first semiconductor 120, and the other end extends on the first base layer 110, and the plurality of first extensions 131 do not contact each other. A plurality of first extensions are arranged at intervals on each first extension 131, and the first extensions extend from the first extension 131 to its periphery. And / or, the second good conductor 230 includes a plurality of second extensions 231 and a plurality of second extensions 232, one end of the second extension 231 is connected to the second semiconductor 220, and the other end extends on the second base layer 210, and the plurality of second extensions 231 do not contact each other. A plurality of second extensions 232 are arranged at intervals on each second extension 231, and the second extensions 232 extend from the second extension 231 to its periphery.

[0050] The pressing sensitivity of the fabric touch device can be improved by providing the first extension part and / or the second extension part 232. In some embodiments, the first extension part 131 and the second extension part 231 are generally strip-shaped structures. When the user's finger presses the intersection of the first extension part 131 and the second extension part 231, the first extension part 131 and the second extension part 231 can be brought into contact and conduction. That is, the sensitivity of the touch device in these embodiments generally depends on the distribution density of the first extension part 131 and the second extension part 231. In this embodiment, by adding the first extension part and / or the second extension part 232, the area covered by the first good conductor 130 is increased by the first extension part, and the area covered by the second good conductor 230 is increased by the second extension part 232, so that when the user presses the fabric touch device, it is easier to achieve contact and conduction between the first good conductor 130 and the second good conductor 230, which is conducive to improving the pressing sensitivity of the fabric touch device.

[0051] Please refer to Figure 1-7It should be noted that the first good conductor 130 can be arranged below the first base layer 110, that is, the side of the first base layer 110 facing the second conductive layer 200, and the second good conductor 230 can conduct electricity on both the front and back sides of the second base layer 210. The resistivity of the first semiconductor 120, the second semiconductor 220 and the third semiconductor 320 can be different or the same. When the resistivity of the first semiconductor 120 and the second semiconductor 220 is different, and the multiple first extensions 131 are led out from different positions of the first semiconductor 120, and the multiple second extensions 231 are led out from different positions of the second semiconductor 220, when the user presses different positions to make the first extension 131 and the second extension 231 contact and conduct, the resistance value of the first conductive path is unique, so that it is convenient to correspond the plane position coordinates with the resistance value. When the resistivity of the first semiconductor 120 and the second semiconductor 220 is the same, the position where the first extension portion 131 is led out from the first semiconductor 120 and the position where the second extension portion 231 is led out from the second semiconductor 220 can be intentionally set so that the on-resistance value at any point in the plane is a unique value, thereby corresponding the resistance value to the plane position coordinates one by one.

[0052] For example, the conductor resistivity of the first semiconductor 120 and the second semiconductor 220 may differ by more than one hundred times, the resistance value of the first semiconductor 120 connected to the first conductive path may be an integer multiple of 1000 kΩ, and the resistance value of the second semiconductor 220 connected to the first conductive path may be an integer multiple of 1 kΩ. In this way, when the resistance value of the total series resistance of the first conductive path is four effective digits, such as 9001 kΩ, the first two digits of the total series resistance represent that the lead-out position of the first semiconductor 120 is the position where the 9th first extension portion 131 is located, that is, the horizontal coordinate is 9, and the last two digits of the total series resistance represent that the lead-out position of the second semiconductor 220 is the position where the 1st second extension portion 231 is located, that is, the vertical coordinate is 1, thereby forming a one-to-one correspondence between resistance and position.

[0053] In summary, through the above design, when the user presses on different positions of the fabric touch device, part of the first semiconductor 120 and part of the second semiconductor 220 are connected in series, and the resistance value of the series connection is a unique value, which corresponds to a unique set of coordinates in a plane, so that the user's pressing position can be determined by the resistance value of the first conductive path.

[0054] It should be noted that the position coordinate system formed by the first conductive layer 100 and the second conductive layer 200 is not limited to the Cartesian plane coordinate system, and may also adopt a plane polar coordinate system, a cylindrical coordinate system, a spherical coordinate system, etc. For example, please refer to Figure 3The first semiconductor 120 of the first conductive layer 100 is arranged around a circle, and the first good conductor 130 electrically connected thereto is arranged radially. The second semiconductor 220 of the second conductive layer 200 is arranged along the radius of the circle, and the second good conductor 230 electrically connected thereto is arranged in a plurality of incomplete circular rings, so that it can be used to detect coordinates in a polar coordinate system.

[0055] Please refer to Figure 1-7 , the first preset value of the pressure in this embodiment can be regarded as being smaller than the second preset value. When it is detected that the first conductive path is on and the second conductive path is off, it can be determined that the force applied by the user is greater than the first preset value and less than the second preset value. When both the first conductive path and the second conductive path are on, it can be determined that the force applied by the user is greater than the second preset value. That is, the approximate range of the force applied by the user can be roughly determined simply from the on and off states of the first conductive path and the second conductive path.

[0056] When the pressure applied by the user is greater than the second preset value, so that both the first conductive path and the second conductive path are turned on, the resistance value of the second conductive path is composed of three parts, specifically including the resistance R1 of the corresponding part of the second semiconductor 220 connected to the second conductive path, the contact resistance R2 between the second good conductor 230 and the third semiconductor 320, and the resistance R3 between the contact position of the third semiconductor 320 and the third good conductor 330. That is, the resistance R of the second conductive path = R1 + R2 + R3. When the pressure is greater than or equal to the second preset value, the continued increase in pressure can cause changes in R2 and R3, wherein the change in R2 is due to the change in contact resistance caused by the change in contact area on the one hand, and the change in contact tightness of the same area caused by the change in pressure on the other hand, which also causes the change in contact resistance. Among them, the change in R3 is due to the fact that the pressure changes the length of the third semiconductor 320 connected to the circuit, thereby changing the resistance, and on the other hand, it is due to the fact that the third semiconductor 320 can have a piezoresistive effect and can also change the resistance. Therefore, when the pressure is greater than both the first pressure setting value and the second pressure setting value, the change in pressure can be characterized by detecting the change in the resistance R of the second conductive path. In short, under the combined effect of multiple factors, the greater the pressure applied by the user, the smaller the resistance of the second conductive path. Therefore, the change in the pressure applied by the user can be identified by the change in the resistance of the second conductive path.

[0057] Please refer to Figure 1-3In one embodiment, the first good conductor 130, the second good conductor 230 and the third good conductor 330 can all use metal-plated conductive fabrics such as copper-plated conductive fabrics, silver-plated conductive fabrics, and other conductive fabrics containing metal components. The first base layer 110, the second base layer 210 and the third base layer 310 can all use polyester plain woven fabrics. The first semiconductor 120 and the second semiconductor 220 can both preferably be polyurethane composite materials doped with graphene or carbon nanotubes. The first semiconductor 120 recommends a length resistance range of 0 to 1,000 ohms per centimeter, and the second semiconductor 220 recommends a length resistance range of 100,000 to 200,000 ohms per centimeter. The third semiconductor 320 is preferably a polyurethane composite material doped with graphene, and the recommended length resistance range is 1,000 to 10,000 ohms per centimeter. The elastic isolation layer 500 can all be selected from warp-knitted elastic knitted fabrics woven from polyurethane filaments. The elastic isolation layer 500 can also be selected from an elastic structure printed with a styrene block copolymer type thermoplastic elastomer. The adhesive should be a hot-melt polyurethane film, but the adhesive cannot cover the semiconductors and good conductors of each conductive layer, otherwise a short circuit will occur. Therefore, you can also use sewing to sew the five layers of material together in the non-touch area to avoid the occurrence of short circuits.

[0058] Please refer to Figure 1 and 2 In one embodiment, the number of the first extension part 131 and the second extension part 231 are both five, and the first extension part 131 divides the first semiconductor 120 equally, and the second extension part 231 divides the second semiconductor 220 equally. According to the difference of the first extension part 131 connected to the first conductive path, the resistance value of the part of the first semiconductor 120 connected to the first conductive path is also different. For example, according to Figure 1 Counting from right to left, the resistance value of the first semiconductor 120 connected when the first extension 131 is turned on can be 200 ohms, 400 ohms, 600 ohms, 800 ohms, and 1,000 ohms. Similarly, the second extension 231 divides the second semiconductor 220 into 20,000 ohms, 40,000 ohms, 60,000 ohms, 80,000 ohms, and 100,000 ohms that can be connected to the first conductive path. In this way, when the user presses the intersection of the first good conductor 130 and the second good conductor 230, the multimeter can measure the resistance, for example, 40,600 ohms, which can be inferred to be the intersection of the third first good conductor 130 and the second second good conductor 230.

[0059] Please refer to Figure 2In one embodiment, the first semiconductor 120 and the second semiconductor 220 are both configured as a plurality of disconnected parts, the disconnected gaps in the first semiconductor 120 are connected by the first good conductor 130, and the disconnected gaps in the second semiconductor 220 are connected by the second good conductor 230. This embodiment does not require a huge difference in resistance between the first semiconductor 120 and the second semiconductor 220, but only requires that the resistance value of each intersection of the first good conductor 130 and the second good conductor 230 is different. For example, Figure 2 The resistance values ​​of the 25 intersections where the first good conductor 130 and the second good conductor 230 can be connected can be set to 211 kOhm, 228 kOhm, 239 kOhm, 248 kOhm, 261 kOhm, 278 kOhm, 289 kOhm, 301 kOhm, 316 kOhm, 333 kOhm, 359 kOhm, 378 kOhm, 399 kOhm, 414 kOhm, 438 kOhm, 450 kOhm, 479 kOhm, 490 kOhm, 512 kOhm, 535 kOhm, 565 kOhm, 587 kOhm, 609 kOhm, 635 kOhm, 666 kOhm. Of course, in other embodiments, it can also be flexibly adjusted according to actual conditions, as long as the resistance value of each intersection of the first good conductor 130 and the second good conductor 230 is different.

[0060] Please refer to Figure 1-7 In one embodiment, the third good conductor 330 includes a main body 331, a plurality of third extensions 332 and a plurality of third expansions 333. One end of the third extension 332 is connected to the main body 331, and the other end extends on the third base layer 310, and the plurality of third extensions 332 do not contact each other. A plurality of third expansions 333 are arranged at intervals on each third extension 332, and the third expansions 333 extend from the third extension 332 to its periphery. The third semiconductor 320 covers the third extension 332 and the third expansion 333.

[0061] On the one hand, when the user presses the fabric touch device and the applied force is greater than the second preset value, the second good conductor 230 is brought into contact with the third semiconductor 320, thereby connecting the second conductive path. At this time, the current may flow in the direction of the second semiconductor 220, the second good conductor 230, the third semiconductor 320, and the third good conductor 330 in sequence. On the other hand, since the third good conductor 330 includes a plurality of third extensions 332 and a plurality of third extensions 333, the current can flow to the nearest third extension 332 or third extension 333 after passing through the covered third semiconductor 320, thereby reducing the flow distance of the current on the third semiconductor 320 and reducing the influence of the flow distance of the current on the third semiconductor 320 on the resistance of the second conductive path, thereby highlighting the influence of the piezoresistance effect on the resistance of the second conductive path, so that the continuous change of the pressure applied by the user can be more accurately characterized by the change of the resistance of the second conductive path.

[0062] Please refer to Figure 1-7 In one embodiment, the second good conductor 230 includes a plurality of second extension portions 231 and a plurality of second expansion portions 232 , and the second expansion portions 232 and the third expansion portions 333 are arranged one-to-one correspondingly in a direction perpendicular to the second conductive layer 200 .

[0063] When the user presses the fabric touch device, if the user's pressing position coincides with the second extension part 232 and the third extension part 333 in a direction perpendicular to the second conductive layer 200, as the user's pressing force changes, the current flow path of the second conductive path and / or the contact area between the second extension part 232 and the third extension part 333 will change significantly, so that when the user's pressing force changes, the resistance of the second conductive path changes more significantly, which is conducive to better characterizing the change in the user's pressing force through the change in the resistance of the second conductive path. Of course, the specific effect is also related to the shape of the second extension part 232 and the third extension part 333, which will be described in detail later in conjunction with specific embodiments.

[0064] Please refer to Figure 1-7 In one embodiment, the shape of the second extension portion 232 is the same as the shape of the third extension portion 333, or the third extension portion 333 has a closed outer contour, and the orthographic projection of the second extension portion 232 on the plane where the third conductive layer 300 is located is located in the third extension portion 333, and at least part of the orthographic projection coincides with the outer contour of the third extension portion 333.

[0065] Please refer to Figure 1-6, when the second extension part 232 and the third extension part 333 have the same shape, as the user's pressing force increases, the contact area between the second extension part 232 and the third extension part 333 gradually increases, thereby reducing the resistance of the second conductive path. Specifically, when the user's pressing force is small, the deformation of the second conductive layer 200 and the elastic isolation layer 500 is small, so that the second extension part 232 and the third extension part 333 are only in contact at the center of the force. When the user's pressing force gradually increases, the deformation of the second conductive layer 200 and the elastic isolation layer 500 increases, and the second extension part 232 passes through the through hole more, thereby increasing the contact area between the second extension part 232 and the third extension part 333.

[0066] Combination Figure 7 , and when the second extension part 232 is a geometric figure and the third extension part 333 is a frame with a closed outer contour, if the pressure applied by the user is small, the force squeezes along the center of the second extension part 232 to the blank part in the frame of the third extension part 333. At this time, after the current flows from the second extension part 232 to the center of the frame, it will continue to flow along the shortest path to the outer contour of the frame, and the resistance of this part of the path is large, and then continue to flow along the third good conductor 330. If the pressure applied by the user is large, the force squeezes the outer part of the second extension part 232 directly to the outer contour of the frame. At this time, after the current passes through the third semiconductor 320, it will directly flow to the outer contour of the frame, so that the flow path of the current changes, thereby greatly reducing the resistance of the second conductive path.

[0067] It is understandable that the shape matching of the second extension part 232 and the third extension part 333 in the above-mentioned solutions also realizes the characterization of the change of the user's pressing force by the change of the resistance of the second conductive path. That is, it is possible to achieve the purpose of "characterizing the change of the user's pressing force by the change of the resistance of the second conductive path" by matching the shapes of the second extension part 232 and the third extension part 333 instead of relying on the piezoresistance effect. This allows the third conductive layer 300 to also be made of a hard material (with an insignificant piezoresistance effect), for example, a third base layer 310 made of PI plastic material is selected, and a third good conductor 330 is formed on the third base layer 310 by metal powder.

[0068] Please refer to Figure 4 , 6, 7 and 12, specifically, the shapes of the first extension portion, the second extension portion 232, the third extension portion 333 and / or the fourth extension portion 423 can be any shape, for example, a circle, a polygon, a wave shape, a fractal structure, a ray shape, a straight line shape of an array, a combination of multiple shapes or other irregular shapes, etc. The shapes of the first extension portion 131, the second extension portion 231, the third extension portion 332 and the fourth extension portion 422 can also be any shape, for example, a straight line, a wave shape, a curve, a triangle, a rectangle, a square or other irregular shapes, etc. The shapes of the first semiconductor 120 and the second semiconductor 220 can be a continuous straight line segment, a plurality of discontinuous straight line segments, an arc shape or any other suitable shape.

[0069] Please refer to Figure 1 and 2 In one embodiment, the third base layer 310 has a first region and a second region adjacent to each other, the third semiconductor 320 covers the first region, the third good conductor 330 covers the second region, and the third semiconductor 320 is adjacent to the third good conductor 330 .

[0070] When the user presses the fabric touch device and the force is greater than the second preset value, the second good conductor 230 contacts the third semiconductor 320, so that the second conductive path is turned on. When the current flows through the third semiconductor 320, it flows from the first area to the second area in the shortest path, thereby flowing from the third semiconductor 320 to the third good conductor 330, and the resistance of this part of the path is relatively large. That is, at this time, the resistance of the second conductive path is not only affected by the piezoresistance effect, but also by the pressing position.

[0071] Please refer to Figure 1-4 8-10, in one embodiment, the fabric touch device further includes at least one fourth conductive layer 400, which is stacked on the side of the third conductive layer 300 facing the second conductive layer 200 or the side away from the second conductive layer 200. The fourth conductive layer 400 includes a fourth base layer 410 and a fourth good conductor 420, and the fourth good conductor 420 covers the fourth base layer 410, and each fourth conductive layer 400 has a corresponding third preset value. The fabric touch device is in a non-stressed state, and the fourth conductive layer 400 is isolated from the adjacent second conductive layer 200 or third conductive layer 300. When the fabric touch device is in a stressed state and the applied force is greater than the third preset value, the fourth conductive layer 400 forms a third conductive path with the second conductive layer 200 or the third conductive layer 300, so that the gradient change of the applied force is characterized by the number of layers of the third conductive layer 300 connected in the third conductive path.

[0072] On the one hand, since the fourth conductive layer 400 has only two states, namely, on and off, its structure is simple, and its stability and robustness are good. On the other hand, the gradient change of the magnitude of the force can be characterized by the number of layers of the fourth conductive layer 400 connected to the third conductive path. For example, when the fourth conductive layer 400 is provided with multiple layers, if one layer of the fourth conductive layer 400 is connected to the third conductive path, it can be detected that the fourth conductive layer 400 is switched to the on state, thereby judging that the pressure applied by the user has reached the first gradient value. If the pressure is greater, so that two layers of the fourth conductive layer 400 are connected to the third conductive path, it can be judged that the pressure applied by the user has reached the second gradient value. Similarly, the situation where three or four fourth conductive layers 400 are connected to the third conductive path can be deduced in the same way.

[0073] Please refer to Figure 8-13 In one embodiment, the fourth good conductor 420 includes a base portion 421 and a plurality of fourth extension portions 422, one end of the fourth extension portion 422 is connected to the base portion 421, and the other end extends on the fourth base layer 410, and the plurality of fourth extension portions 422 do not contact each other. The fourth good conductor 420 also includes a fourth extension portion 423, a plurality of fourth extension portions 423 are arranged on the fourth extension portion 422 at intervals, and the fourth extension portion 423 extends from the fourth extension portion 422 to the periphery thereof.

[0074] On the one hand, by setting the fourth good conductor 420 to include a base portion 421 and a plurality of fourth extension portions 422, compared with the solution of covering the fourth good conductor 420 as a whole on the fourth base layer 410, the material of the fourth good conductor 420 can be saved, thereby helping to reduce costs. On the other hand, by setting the fourth extension portion 423, the coverage area of ​​the fourth good conductor 420 is expanded, which helps to further ensure the pressing sensitivity of the fabric touch device. Specifically, the fourth extension portion 422 can be set in a one-to-one correspondence with the second extension portion 231 or the third extension portion 332 in a direction perpendicular to the third base layer 310, so that when the user presses the fabric touch device, the second extension portion 231 or the third extension portion 332 is in contact with the fourth extension portion 422.

[0075] Please refer to Figure 8-13In one embodiment, the fourth good conductor 420 includes two base parts 421, the two base parts 421 are respectively arranged on opposite sides of the fourth base layer 410, a part of the plurality of fourth extension parts 422 is connected to one of the two base parts 421, and another part of the plurality of fourth extension parts 422 is connected to the other of the two base parts 421. The third preset value includes at least two different gradient values, and each third conductive layer 300 corresponds to two gradient values. When the fabric touch device is in a force-bearing state, and the force is greater than the first gradient value of the third preset value, one of the two base parts 421 is connected to the third conductive path. When the force is greater than the second gradient value of the third preset value, the other of the two base parts 421 is also connected to the third conductive path.

[0076] When the user presses the touch device, if the pressure reaches the first gradient value of the third preset value, one of the two base parts 421 is connected to the third conductive path, and if the pressure reaches the second gradient value of the third preset value, the other of the two base parts 421 is also connected to the third conductive path. By detecting the number of base parts 421 connected to the third conductive path, it can be used to determine whether the user's pressing force reaches the corresponding gradient value. That is, the detection of two gradient values ​​can be achieved through a single-layer fourth conductive layer 400.

[0077] Specifically, the two base parts 421 are respectively the first base part 4211 and the second base part 4212. When the fourth conductive layer 400 is arranged adjacent to the second conductive layer 200, in the direction perpendicular to the fourth conductive layer 400, the fourth extension part 422 connected to the first base part 4211 can be arranged one-to-one with the second extension part 231, and the fourth extension part 422 connected to the second base part 4212 is misaligned with the second extension part 231. When the user presses with a smaller pressure of the first gradient value, the force-bearing part of the second conductive layer 200 is less deformed, and the through hole of the elastic isolation layer 500 is opened smaller due to the deformation, so that only a small area of ​​the second expansion part 232 on the second extension part 231 passes through the through hole, thereby contacting with the fourth extension part 422 connected to the first base part 4211, and then the first base part 4211 is turned on. When the user presses with a larger pressure of the second gradient value, the force-bearing part of the second conductive layer 200 is greatly deformed, and the through hole of the elastic isolation layer 500 is opened wider due to the deformation, so that a larger part of the area of ​​the second extension part 232 on the second extension part 231 passes through the through hole, thereby contacting the fourth extension part 422 connected to the first base part 4211 and the fourth extension part 422 connected to the second base part 4212, thereby making the first base part 4211 and the second base part 4212 conductive. Of course, the above working process can also be achieved without relying on the second extension part 232, but by increasing the width of the second extension part 231.

[0078] It can be understood that, based on the same principle, when another fourth conductive layer 400 is provided above the fourth conductive layer 400, the upper fourth conductive layer 400 can be set to have only one base portion 421, and the lower fourth conductive layer 400 can be set to have a first base portion 4211 and a second base portion 4212, and the fourth extension portion 422 connected to the first base portion 4211 is arranged one-to-one with the fourth extension portion 422 of the upper fourth conductive layer 400, while the fourth extension portion 422 connected to the second base portion 4212 is staggered at a certain position.

[0079] Please refer to Figure 1-7 In one embodiment, the fabric touch device further includes an elastic isolation layer 500, which is stacked between the first conductive layer 100 and the second conductive layer 200, and / or between the second conductive layer 200 and the third conductive layer 300. The elastic isolation layer 500 has through holes, so that when subjected to external force, the first conductive layer 100 and the second conductive layer 200 can contact each other through the through holes to form a first conductive path, and / or the second conductive layer 200 and the third conductive layer 300 can contact each other through the through holes to form a second conductive path.

[0080] When the fabric touch device is in a non-stressed state, the elastic isolation layer 500 disposed between the first conductive layer 100 and the second conductive layer 200 is used to isolate the first conductive layer 100 and the second conductive layer 200, and the elastic isolation layer 500 disposed between the second conductive layer 200 and the third conductive layer 300 is used to isolate the second conductive layer 200 and the third conductive layer 300. When the fabric touch device is in a stressed state, and the applied force is greater than the first preset value, the first conductive layer 100 squeezes the elastic isolation layer 500, causing the elastic isolation layer 500 to deform, thereby causing the first conductive layer 100 to contact the second conductive layer 200 through the through hole, thereby causing the first conductive path to be conductive. When the fabric touch device is in a stressed state, and the applied force is greater than the second preset value, similarly, the second conductive layer 200 and the third conductive layer 300 are in contact with each other through the through hole, thereby causing the second conductive path to be conductive.

[0081] Please refer to Figure 1-7 In one embodiment, the fabric touch device further includes a non-conductive protrusion structure (not shown), which is disposed between the first conductive layer 100 and the second conductive layer 200, and / or between the second conductive layer 200 and the third conductive layer 300. The protrusion structure is used to play a supporting role, so that the first conductive layer 100 and the second conductive layer 200 are isolated by the gap, and / or the second conductive layer 200 and the third conductive layer 300 are isolated by the gap.

[0082] When the fabric touch device is in a non-stressed state, the protrusion structure arranged between the first conductive layer 100 and the second conductive layer 200 keeps the first conductive layer 100 and the second conductive layer 200 isolated by the gap, and the protrusion structure arranged between the second conductive layer 200 and the third conductive layer 300 keeps the second conductive layer 200 and the third conductive layer 300 isolated by the gap. When the fabric touch device is in a stressed state, and the applied force is greater than the first preset value, the stressed part of the first conductive layer 100 is deformed to protrude toward the side where the gap is located, so that the first conductive layer 100 and the second conductive layer 200 are in contact with each other, thereby making the first conductive path conductive. When the fabric touch device is in a stressed state, and the applied force is greater than the second preset value, similarly, the second conductive layer 200 and the third conductive layer 300 are in contact with each other, thereby making the second conductive path conductive.

[0083] Please refer to Figure 1-7 It should be noted that the elastic isolation layer 500 and the protrusion structure can also be used in combination freely. For example, the elastic isolation layer 500 can be set between the first conductive layer 100 and the second conductive layer 200, and the protrusion structure can be set between the second conductive layer 200 and the third conductive layer 300. The spatial resolution of the fabric touch device can be achieved by changing the distribution density of the first good conductor 130 pattern in the first conductive layer 100 and the distribution density of the second good conductor 230 pattern in the second conductive layer 200, which may be accompanied by a change in the size of the through holes on the elastic isolation layer 500, or a change in the density of the non-conductive protrusions in the first conductive layer 100 and the second conductive layer 200. The pressing sensitivity of the fabric touch device is also related to the thickness of the elastic isolation layer 500 material, the elastic modulus, and the size and shape of the through holes.

[0084] The elastic isolation layer 500 can be a film or fabric (woven fabric, knitted fabric, braided fabric or non-woven fabric), and the material can be silicone, polyurethane, or other elastic polymer materials, so it has elasticity and can be bent and stretched at will. For example, elastic mesh fabric made of elastic fibers, elastic mesh fabric or elastic fabric with loose structure, etc. In addition, the additional elastic isolation layer 500 is made into a hole or mesh shape to limit the touch position to avoid touching the non-functional area. The protrusion structure includes protrusions formed by fiber weaving, and protrusions formed by dispensing polymer materials such as silicone, etc.

[0085] Please refer to Figure 1-48-10, the first base layer 110, the second base layer 210, the third base layer 310, the fourth base layer 410 and the elastic isolation layer 500 can all be made of textile materials, which makes them have the advantages of textiles such as softness, bendability, washability and dryability. The first conductive layer 100, the second conductive layer 200, the third conductive layer 300, and the possible fourth conductive layer 400 and the elastic isolation layer 500 can be bonded with adhesives, hot melt films, etc., or integrated by sewing, and the above-mentioned multiple layers can be directly woven into a whole using three-dimensional weaving technology, or the above-mentioned methods can be combined. The first conductive layer 100, the second conductive layer 200, the third conductive layer 300, and the possible fourth conductive layer 400 and the elastic isolation layer 500 are not limited to plane structures, but can also be curved structures, so that they can better fit curved objects such as the human body, etc. It can even be processed into a three-dimensional structure to cover a three-dimensional object, thereby forming a three-dimensional single-point perception.

[0086] The first semiconductor 120, the second semiconductor 220, the third semiconductor 320, the first good conductor 130, the second good conductor 230, the third good conductor 330 and the fourth good conductor 420 can be conductive film materials, conductive composite materials, conductive fiber materials, or conductive fiber aggregate materials, preferably flexible conductive polymer materials or conductive composite materials, such as polyimide films doped with graphene, polyethylene terephthalate films doped with carbon nanotubes, carbon fibers, etc. It is also possible to form a conductive part with a certain specification pattern on the surface or a certain part in the middle of the substrate by screen printing, plate printing, spraying or thermal bonding, weaving, sewing or embroidery. It is also possible to use a double-layer or multi-layer flexible conductive film obtained by deposition, chemical plating, electrochemical plating, etc. Of course, the conductive layer can also be a fabric with a metal coating or a conductive composite coating or an intrinsic conductive polymer coating, a fabric woven from conductive fibers, or a fabric woven from conductive fibers and non-conductive fibers.

[0087] The above specific examples are used to illustrate the present invention, which is only used to help understand the present invention and is not intended to limit the present invention. For those skilled in the art, according to the concept of the present invention, some simple deductions, modifications or substitutions can be made.
