Description

Technical Field

[0001] The present application relates to the field of electronic technologies, and in particular, to a fabric and a terminal. Background Art

[0002] With the development of textile technology and the improvement of people's living standards, fabrics are gradually developing towards functionality and intelligence. Due to the characteristics of fabrics such as softness and stable structure, compared with traditional printing coating processes, fabrics have more stable sensing capabilities, and thus can be widely used in various terminals to sense different modalities of information. For example, the surface of the steering wheel of a vehicle can be a fabric capable of sensing the physiological information of the user. Another example is that the surface of a seat (for example, the surface of the backrest of the seat, the surface of the armrest) can be a fabric capable of sensing touch information and pressure information.

[0003] However, the above-mentioned fabrics can only achieve the sensing of one type of information on the same piece of fabric. In some other application scenarios, it is necessary to simultaneously sense different modalities of information on the same piece of fabric. For example, the surface of the seat armrest needs to have three sensing parts to respectively achieve the sensing of physiological information, touch information, and pressure information.

[0004] To achieve this multi-in-one sensing function, in some technical solutions, different fabrics for realizing different sensing functions can be spliced together by sewing or other means. However, there are certain differences in the forming processes and materials of different fabrics, and there is a sewing structure for splicing and fixing between different fabrics. Therefore, the tactile feel of the spliced fabric and the aesthetics of the appearance are limited.

[0005] For this reason, in some other technical solutions, conductive fibers can also be woven into different regions of the same piece of fabric or a conductive coating can be printed to achieve different sensing functions. However, the sensing parts of different sensing functions have different requirements for the mechanical properties of the fabric (for example, elasticity or compressibility). Currently, it is difficult for the same piece of fabric to be compatible with the different requirements of different sensing functions for the mechanical properties of the fabric, and the sensing effect needs to be improved. Summary of the Invention

[0006] Some embodiments of the present application provide a fabric and a terminal. The present application is introduced from multiple aspects below, and the embodiments and beneficial effects of the following multiple aspects can be referred to each other.

[0007] In a first aspect, an embodiment of the present application provides a fabric. The fabric includes a first braid and a second braid located in different regions, wherein the first braid and the second braid are respectively used to achieve different sensing functions, the first braid and the second braid are connected through a braiding structure, and the braiding material of the second braid is different from that of the first braid, so that at least one mechanical property of the second braid is different from that of the first braid.

[0008] According to an embodiment of the present application, the weaving material of the second woven body is different from that of the first woven body, so that at least one mechanical property of the second woven body can be different from that of the first woven body. In this way, different mechanical properties required for different sensing functions can be better balanced, thereby improving the sensing effect of the fabric. In addition, the fabric provided by the present application can be integrally produced based on existing industrial equipment (for example, knitting machines), without going through multiple forming processes, with low forming difficulty and production cost, and high production efficiency.

[0009] In some embodiments, the weaving material of the second woven body includes functional fibers different from those of the first woven body, so that the elasticity of the second woven body is less than that of the first woven body. Thereby, the stability of the second woven body for sensing information can be effectively improved.

[0010] In some embodiments, the second woven body is used to sense touch information. The second woven body includes a conductive layer and an insulating layer arranged in a stacked manner. The conductive layer is woven by conductive fibers and functional fibers together, and / or the insulating layer is woven by insulating fibers and functional fibers together. Thereby, the stability of the second woven body for sensing touch information can be effectively improved.

[0011] In some embodiments, the conductive layer is woven by conductive fibers and functional fibers together. The conductive fibers and the functional fibers can be woven in one of the following ways: the functional fibers and the conductive fibers are wound or arranged side by side to jointly form a fiber group for weaving, and the functional fibers and the conductive fibers are alternately arranged for weaving.

[0012] In some embodiments, the conductive layer includes a plurality of conductive regions, and the plurality of conductive regions are arranged in a one-dimensional array or a two-dimensional array. Thereby, different touch information can be sensed.

[0013] In some embodiments, the plurality of conductive regions are arranged in a two-dimensional array. Among them, the conductive layer includes two sub-conductive layers arranged in a stacked manner. The stacking direction of the two sub-conductive layers is parallel to the stacking direction of the conductive layer and the insulating layer. The two sub-conductive layers respectively include a plurality of sub-conductive regions. The plurality of sub-conductive regions of the two sub-conductive layers are all arranged in a one-dimensional array, and the arrangement directions of the plurality of sub-conductive regions of the two sub-conductive layers are perpendicular to each other. In this way, the second woven body can sense the sliding touch in the two-dimensional direction and the specific position of the touch, thereby expanding the scope of application.

[0014] In some embodiments, the second woven body is used to sense touch information. The second woven body includes a conductive layer, and the conductive layer is woven by conductive fibers and functional fibers together, and the functional fibers are wrapped around the outer periphery of the conductive fibers. Thereby, the stability of the second woven body for sensing touch information can be effectively improved.

[0015] In some embodiments, the second braided body is used to sense pressure information. The second braided body includes two conductive layers arranged in a stacked manner, and the two conductive layers are insulated from each other. Moreover, at least one of the two conductive layers is formed by co-weaving conductive fibers and functional fibers. Thereby, the stability of the second braided body in sensing pressure information can be effectively improved.

[0016] In some embodiments, the functional fibers include thermoplastic fibers.

[0017] According to the embodiments of the present application, the thermoplastic fibers can be melted under the action of heat and partially adhere to or coat other braided materials of the second braided body. After the thermoplastic fibers are cooled, the elasticity of the second braided body can be restricted, thereby improving the stability of the sensed information.

[0018] In some embodiments, the thermoplastic fibers are any one of polyamide fibers, polyester fibers, or polypropylene fibers.

[0019] In some embodiments, the braided materials of the second braided body include functional fibers different from those of the second braided body, so that the compressibility of the second braided body is less than that of the first braided body. Thereby, the range of pressure that the second braided body can sense can be increased.

[0020] In some embodiments, the second braided body is used to sense pressure information. The second braided body includes two conductive layers arranged in a stacked manner and an insulating layer disposed between the two conductive layers. The insulating layer is formed by co-weaving insulating fibers and functional fibers. Thereby, the range of pressure that the second braided body can sense can be increased.

[0021] In some embodiments, the functional fibers include elastic fibers.

[0022] According to the embodiments of the present application, the elastic fibers can provide elastic support for the second braided body, making the second braided body less compressible, that is, reducing the compressibility of the second braided body, so that the second braided body can sense a larger range of pressures.

[0023] In some embodiments, the material of the elastic fibers is any one of polyurethane, polyacrylate, or polyester.

[0024] In some embodiments, the two conductive layers respectively include a plurality of conductive regions, and the plurality of conductive regions of the two conductive layers are all arranged in a one-dimensional array. Moreover, along the stacking direction of the two conductive layers, the projections of the plurality of conductive regions of the two conductive layers on the insulating layer coincide with each other. Thereby, the second braided body can sense pressures at multiple different positions in a one-dimensional direction.

[0025] In some embodiments, the two conductive layers each include a plurality of conductive regions, the plurality of conductive regions of the two conductive layers are arranged in a one-dimensional array, and the arrangement directions of the plurality of conductive regions of the two conductive layers are perpendicular to each other, or the plurality of conductive regions of the two conductive layers are arranged in a two-dimensional array, and along the stacking direction of the two conductive layers, the projections of the plurality of conductive regions of the two conductive layers on the insulating layer coincide with each other. Thus, the second braided body can sense pressures at multiple different positions in two-dimensional directions.

[0026] In some embodiments, the first braided body is used to sense physiological information, and the first braided body includes a conductive layer woven from conductive fibers.

[0027] In some embodiments, the first braided body is used to sense touch information or physiological information.

[0028] In some embodiments, the braided structure is woven from insulating fibers.

[0029] In some embodiments, the conductive fibers are carbonaceous fibers, copper wires, silver wires, stainless steel wires, or natural fibers or synthetic chemical fibers coated with a conductive material.

[0030] In some embodiments, the conductive material is gold, silver, silver nanowires, or copper.

[0031] In some embodiments, the insulating fibers are cotton fibers, wool fibers, linen fibers, silk fibers, polyester fibers, spandex fibers, acrylic fibers, aramid fibers, nylon fibers, acrylic fibers, polypropylene fibers, polyester fibers, or nylon fibers.

[0032] In a second aspect, embodiments of the present application provide a terminal, which includes a main body and any one of the fabrics in the first aspect and possible implementations of the first aspect described above. BRIEF DESCRIPTION OF THE DRAWINGS

[0062] To make the objectives, technical solutions, and advantages of the present application clearer, the following will further describe the implementation manners of the present application in detail with reference to the accompanying drawings.

[0063] First, some concepts or terms involved in the present application are explained to facilitate understanding by those skilled in the art.

[0064] (1) Sensing physiological information

[0065] Figure 1A Shows a schematic diagram of sensing physiological information in the embodiments of the present application. Refer to Figure 1A , when the user's skin is in direct contact with the conductive layer 101, the conductive layer 101 can act as a sensor to obtain physiological information on the skin surface, for example, electrocardiogram signals, electromyogram signals, or galvanic skin response signals, etc.

[0066] (2) Sensing touch information

[0067] Figure 1B The figure shows a schematic diagram of sensing touch information in an embodiment of the present application. Referring to Figure 1B , the touch information can be sensed according to the amplitude change of the capacitance signal. Specifically, the conductive layer 201 and the insulating layer 202 are stacked. Among them, the conductive layer 201 can form an electric field and generate a capacitance signal. The insulating layer 202 is used to contact the user's finger to prevent the user's finger from directly contacting the conductive layer 201, thereby avoiding the influence of the user's finger on the generation of the capacitance signal. When the user's finger approaches the conductive layer 201, the amplitude of the capacitance signal increases; conversely, when the user's finger moves away from the conductive layer 201, the amplitude of the capacitance signal decreases. Therefore, the touch information can be sensed according to the amplitude change of the capacitance signal. Among them, the touch information can be single click, double click, long press, swipe up, swipe down, swipe left, swipe right, pinch, multi-finger flick, and full hand interaction (for example, using the user's full hand to touch the fabric, using the user's full hand to cover the fabric, using the user's full hand to press the fabric, palm touch, and flipping, twisting or rotating the user's hand while touching the fabric), etc.

[0068] (3) Sensing pressure information

[0069] Figure 1C The figure shows a schematic diagram of sensing pressure information in an embodiment of the present application. Referring to Figure 1C , the pressure information can be sensed according to the amplitude change of the capacitance signal. Specifically, the first conductive layer 301a and the second conductive layer 301b are stacked, and an insulating layer 302 is also provided between the first conductive layer 301a and the second conductive layer 301b. Among them, the first conductive layer 301a, the second conductive layer 301b and the insulating layer 302 together form a parallel plate capacitor. The capacitance value of the parallel plate capacitor depends on the areas of the first conductive layer 301a and the second conductive layer 301b, and the distance D1 between the first conductive layer 301a and the second conductive layer 301b. When the user presses on the first conductive layer 301a, the distance D1 between the first conductive layer 301a and the second conductive layer 301b decreases, thereby increasing the amplitude of the capacitance. The degree of increase in the capacitance amplitude is related to the magnitude of the pressure applied by the user to the first conductive layer 301a. Therefore, the pressure information can be sensed according to the amplitude change of the capacitance, for example, identifying the pressing at different positions or the magnitude of the pressure.

[0070] The embodiment of the present application is used to provide a fabric and a terminal including the fabric. The fabric provided by the embodiment of the present application is integrally formed, and the fabric can realize a variety of different sensing functions (for example, the touch information, pressure information or physiological information described above), and for different sensing functions, the fabric has different mechanical properties in different parts, so as to effectively improve the sensing effect.

[0071] It can be understood that the terminal provided in this application includes, but is not limited to, any one of terminals with a fabric surface such as vehicles, wearable devices (for example, augmented reality (AR) glasses, virtual reality (VR) glasses, mixed reality (MR) glasses, smart helmets, smart watches, smart bracelets), and smart home terminals (for example, smart sofas, smart massage chairs), etc. This application does not make specific limitations thereto. For ease of description, the technical solution of this application will be introduced below by taking the terminal as a vehicle as an example.

[0072] Figure 2 Fig. shows an exemplary structural diagram of vehicle 1 in an embodiment of this application. Refer to Figure 2 , vehicle 1 includes fabric 10, body 11, seat 12, and steering wheel 13. Among them, a carriage 14 is formed inside body 11. Seat 12 and steering wheel 13 are arranged inside carriage 14.

[0073] Among them, seat 12 includes armrest 15, seat cushion 16, backrest 17, and headrest 18. Exemplarily, fabric 10 can cover armrest 15 (as an example of the main body) of seat 12 and serve as the outer surface of armrest 15. It should be noted that in the embodiments of this application, the outer surface of each component refers to the surface of each component facing the user during actual use, that is, the surface of each component for direct contact with the user; the surface opposite to the outer surface is the inner surface, that is, the surface of each component facing away from the user during actual use, which will not be elaborated below.

[0074] Fabric 10 can be used to sense information of one or more modalities to facilitate intelligent interaction inside the vehicle.

[0075] In some embodiments of this application, fabric 10 can be used to sense physiological information. Exemplarily, when the user's hands respectively contact fabric 10 on armrests 15 on both sides of seat 12, information such as the user's heart rate and electrocardiogram can be obtained, and then the user's health status, fatigue level, and stress state can be judged based on information such as heart rate and electrocardiogram to facilitate the user's health monitoring.

[0076] In some embodiments of the present application, the fabric 10 can also be used to sense touch information. When the user makes specific touch gestures on the fabric 10 (for example, single click, double click, long press, swipe up, swipe down, swipe left, swipe right, pinch, multi-finger flick, and full hand interaction (such as using the user's full hand to touch the fabric, using the user's full hand to cover the fabric, using the user's full hand to press the fabric, palm touch, and flipping, twisting or rotating the user's hand while in contact with the fabric), etc.), the vehicle 1 can perform the operations corresponding to the gesture. For example, music playback, music switching, pausing, playing or switching the content played on the in-vehicle screen, etc.

[0077] In some embodiments of the present application, the fabric 10 can also be used to sense pressure information. Exemplarily, when the user presses different positions of the fabric 10 with different pressures, the vehicle 1 can perform corresponding operations according to the pressing position and the magnitude of the pressure. For example, adjusting the front-back position of the seat 12, the angle of the backrest 17 of the seat 12, and the height of the headrest 18 of the seat 12 to improve the comfort of the seat 12.

[0078] It can be understood that the above embodiments only take the fabric 10 being the outer surface of the armrest 15 of the seat 12 as an illustrative example. In other embodiments, the fabric 10 can also be used in other components of the vehicle 1. For example, the fabric 10 can also be used as the outer surface of the steering wheel 13, the seat cushion 16, the backrest 17, the headrest 18, the door handle of the vehicle 1 (not shown) or the roof. The present application makes no limitation thereto.

[0079] In addition, it can be understood that the above Figure 2 only schematically shows some structural components included inside the vehicle 1, and the actual structure and position of these structural components are not limited by Figure 2 And, relative to Figure 2 the structural components shown, the vehicle 1 can also include more or fewer structural components. For example, the vehicle 1 can also include a circuit module and a processor that are communicatively connected to the fabric 10. Among them, the circuit module is used to obtain the signals emitted by the fabric 10 (such as capacitance signals or physiological signals of the user's skin), and the processor is used to analyze and identify the corresponding information (such as touch information, pressure information or physiological information) according to the signals obtained by the circuit module, so as to achieve convenient interaction inside the vehicle.

[0080] As mentioned above, different sensing functions need to be realized through different structures. In order to simultaneously realize the above-mentioned multiple different sensing functions on the same fabric, in some technical solutions, the fabrics used to realize different sensing functions can be spliced together to form a fabric.

[0081] Figure 3 shows a schematic structural diagram of the fabric 10' in some technical solutions. Refer to Figure 3, the fabric 10' is formed by stitching together a first sensing part 100', a second sensing part 200', and a third sensing part 300'. Among them, the first sensing part 100' is used to sense physiological information. The second sensing part 200' is used to sense touch information. The third sensing part 300' is used to sense pressure information.

[0082] Since the first sensing part 100', the second sensing part 200', and the third sensing part 300' are stitched together, there will be a stitching structure 400' between the first sensing part 100', the second sensing part 200', and the third sensing part 300'. The stitching structure 400' will affect the touch feeling and the aesthetics and delicacy of the appearance. Moreover, to achieve different sensing functions, there are also differences in fabric materials and forming processes between the first sensing part 100', the second sensing part 200', and the third sensing part 300', which will also affect the touch feeling and the aesthetics and delicacy of the appearance.

[0083] Therefore, in some other technical solutions, conductive fibers can also be woven or conductive coatings can be printed in different areas of the same piece of fabric to achieve different sensing functions.

[0084] Exemplarily, Figure 4 shows a schematic structural diagram of the fabric 10” in some other technical solutions. Refer to Figure 4 , the fabric 10” includes a fabric body 101” and a conductive layer 102”. The conductive layer 102” is attached to different areas of the fabric body 101” by printing to form sensing parts with different sensing functions.

[0085] Specifically, the conductive layer 102” is attached to the outer surface 1012” of the fabric body 101” so as to jointly form a first sensing part 100” with the fabric body 101”. The first sensing part 100” is used to sense physiological information. The conductive layer 102” is attached to the inner surface 1011” of the fabric body 101” so as to jointly form a second sensing part 200” with the fabric body 101”. The second sensing part 200” is used to sense touch information. The conductive layer 102” is attached to the inner surface 1011” and the outer surface 1012” of the fabric body 101” that are arranged opposite to each other so as to jointly form a third sensing part 300” with the fabric body 101”. The third sensing part 300” is used to sense touch information..

[0086] However, the sensing parts with different sensing functions have different requirements for the mechanical properties of the fabric. The above-mentioned fabric 10 only forms the first sensing part 100, the second sensing part 200, and the third sensing part 300 by adding conductive coatings 102 in different areas of the fabric body 101. Therefore, limited by the performance of the fabric body 101, it is difficult for the fabric 10 to simultaneously meet the different requirements of the sensing parts with different sensing functions for mechanical properties, and the sensing effect needs to be improved.

[0087] For example, for the second sensing part 200 used to sense touch information, it needs to have a small elasticity. If the weaving structure of the second sensing part 200 undergoes obvious deformation and displacement when the user touches the second sensing part 200, it will cause a change in the amplitude of the capacitance signal, thereby affecting the stability of the touch information sensed by the second sensing part 200.

[0088] For the third sensing part 300 used to sense pressure information, it needs to have appropriate compressibility. For example, sensing a large range of pressure requires small compressibility, and sensing a small range of pressure requires large compressibility. In addition, the third sensing part 300 also needs to have small elasticity. If the weaving structure of the conductive layer 102 constituting the third sensing part 300 undergoes obvious deformation and displacement when the user touches the third sensing part 300, it will cause a change in the amplitude of the capacitance signal, thereby affecting the stability of the pressure information sensed by the third sensing part 300.

[0089] To solve the above problems, the present application provides a fabric, which includes at least two sensing parts for realizing different sensing functions. By weaving different weaving materials in one of the sensing parts, the mechanical properties (such as elasticity or compressibility) of this sensing part can be changed, so that the different requirements of different sensing functions for the mechanical properties of the fabric can be met in an integrally formed fabric, effectively improving the sensing effect. The technical solution of the present application will be introduced in detail below with reference to the accompanying drawings.

[0090] Figures 5A to 5C shows a schematic structural diagram of the fabric 10 in an embodiment of the present application, where Figure 5A is a top view of the fabric 10, Figure 5B is a side view of the fabric 10, Figure 5C is for the fabric 10 in Figure 5A a partial enlarged view of the S0 area in. Where, for the convenience of observation and distinction, Figure 5B and Figure 5C each type of filled area in represents a type of fiber. And, Figure 5BThere is a blank gap between two adjacent fabric structures of the fabric 10. However, it can be understood that in actual applications, the fabric 10 has a soft property, so two adjacent fabric structures thereof will come into contact with each other. Additionally Figure 5B only the fiber types included in each layer of the fabric 10 are schematically shown, without limiting the relative position relationship and connection manner between various fibers in each layer. For example, various fibers in the uppermost layer can be Figure 5C interwoven with each other as shown.

[0091] Referring to Figures 5A to 5C , the fabric 10 includes a first braided body (for example, the first sensing part 100 described below) and a second braided body (for example, the second sensing part 200 or the third sensing part 300 described below). The first braided body and the second braided body are located at different positions respectively and are connected by a braided structure 20. That is to say, the first braided body, the second braided body and the braided structure 20 can be integrally formed. Therefore, the fabric 10 can be integrally braided and formed based on existing industrial equipment (for example, a knitting machine).

[0092] The first braided body and the second braided body are respectively used to achieve different sensing functions. Among them, the braiding material of the second braided body is different from that of the first braided body, so that at least one mechanical property of the second braided body is different from that of the first braided body. In this way, different mechanical properties required for different sensing functions can be better taken into account, and then the sensing effect of the fabric 10 can be improved. In addition, compared with the scheme of splicing multiple different fabric materials by sewing and weaving conductive fibers or printing conductive coatings on a piece of fabric, the fabric 10 provided in this application can be integrally produced based on existing industrial equipment (for example, a knitting machine), without going through multiple process forming, with low forming difficulty and production cost and high production efficiency.

[0093] The following introduces several forms of the first braided body and the second braided body in combination with the drawings.

[0094] Continuing to refer to Figures 5A to 5C , in some embodiments of this application, the fabric 10 includes a first sensing part 100 and a second sensing part 200 for achieving different sensing functions. Among them, the first sensing part 100 can be an example of the first braided body. The second sensing part 200 can be an example of the second braided body.

[0095] Among them, the first sensing part 100 is used to sense physiological information. The second sensing part 200 is used to sense touch information. The braiding material of the second sensing part 200 includes functional fibers (for example, thermoplastic fibers 410) different from those of the first sensing part 100, so that the elasticity of the second sensing part 200 is less than that of the first sensing part 100 to ensure the stability of sensing touch information.

[0096] Specifically, the functional fiber includes a thermoplastic fiber 410. The thermoplastic fiber 410 has the characteristics of softening and melting when heated and solidifying when cooled. Therefore, the thermoplastic fiber 410 can melt under the action of heat and partially adhere to or cover other woven materials of the second sensing part 200. After the thermoplastic fiber 410 cools, it can limit the relative movement between the woven structures of the second sensing part 200, making the woven structure of the second sensing part 200 more compact, and thus effectively reducing the elasticity of the second sensing part 200. Ensure that when the user's finger touches the second sensing part 200, the second sensing part 200 is not prone to large-scale deformation or displacement, and the influence of different pressing forces on the deformation of the second sensing part 200 is small, effectively improving the stability of the second sensing part 200 to sense touch information.

[0097] In some embodiments of the present application, the fabric 10 further includes a third sensing part 300 for realizing different sensing functions. Among them, the third sensing part 300 can be another example of the second woven body.

[0098] Among them, the third sensing part 300 is used to sense pressure information. The woven material of the third sensing part 300 includes functional fibers different from those of the second sensing part 200 (for example, the thermoplastic fiber 410), so that the elasticity of the third sensing part 300 is less than that of the first sensing part 100 to ensure the stability of sensing pressure information.

[0099] Specifically, the functional fiber includes a thermoplastic fiber 410. The thermoplastic fiber 410 can melt under the action of heat and partially adhere to or cover other woven materials of the third sensing part 300. After the thermoplastic fiber 410 cools, it can limit the relative movement between the woven structures of the third sensing part 300, making the woven structure of the third sensing part 300 more compact, and thus effectively reducing the elasticity of the third sensing part 300. Ensure that when the user's finger presses the third sensing part 300, the third sensing part 300 is not prone to large-scale deformation or displacement, effectively improving the stability of the third sensing part 300 to sense pressure information.

[0100] For example, Figure 6A shows a schematic diagram of the sensing effect when the third sensing part 300 in the embodiment of the present application does not include the thermoplastic fiber 410. Figure 6B shows a schematic diagram of the sensing effect when the third sensing part 300 in the embodiment of the present application includes the thermoplastic fiber 410. As Figure 6AAs shown, when the third sensing part 300 does not include the thermoplastic fiber 410, there are significant differences in the capacitance change amounts generated by pressing multiple times with different forces. For example, the capacitance change amount when pressing 100 times with a pressure of 20 kPa is about 0.3, while the capacitance change amount when pressing 500 times with a pressure of 20 kPa is about 0.2. This will result in inaccurate perceived pressure information. As Figure 6B shown, after the thermoplastic fiber 410 is provided in the third sensing part 300, the capacitance change amounts generated by pressing multiple times with different forces are substantially the same. Therefore, the third sensing part 300 has better stability in sensing pressure information, and the third sensing part 300 is less affected by pre-stretching and cyclic stretching.

[0101] In some embodiments of the present application, the functional fiber (e.g., the elastic fiber 420) of the third sensing part 300 can also make the compressibility of the third sensing part 300 less than that of the second sensing part 200, so as to be able to sense a larger pressure range.

[0102] Specifically, the functional fiber includes the elastic fiber 420. The elastic fiber 420 has a certain elasticity and can be compressed when subjected to pressure and rebound to the initial state after the pressure is released. Thus, it can provide elastic support for the third sensing part 300, making the third sensing part 300 less likely to be compressed, that is, reducing the compressibility of the third sensing part 300, so that the third sensing part 300 can sense a larger range of pressures.

[0103] It can be understood that the ability of the third sensing part 300 to sense the magnitude of pressure depends on the compressibility of the third sensing part 300. The greater the compressibility of the third sensing part 300, the more sensitive it can be to sense weak pressure changes, while the smaller the compressibility of the third sensing part 300, the larger range of pressure values it can sense.

[0104] In some embodiments of the present application, elastic fibers 420 of different thicknesses can be selected according to the actual application scenario, so that the third sensing part 300 has appropriate compressibility. Among them, the thickness of the elastic fiber 420 can be characterized by the diameter of a single elastic fiber 420. The larger the diameter of a single elastic fiber 420, the thicker the elastic fiber 420, and the smaller the diameter of a single elastic fiber 420, the thinner the elastic fiber 420.

[0105] Figure 7 shows a schematic diagram of the relationship between the pressure range sensed by the third sensing part 300 and the thickness of the elastic fiber 420 in the embodiments of the present application. Refer to Figure 7, when the third sensing part 300 does not include the elastic fiber 420, the capacitance change amount of the third sensing part 300 under different pressures is the most obvious, and the sensitivity is relatively high. Therefore, when the user slightly touches the third sensing part 300, the third sensing part 300 will have a large capacitance change, thus sensing the pressure information, and it is easy to cause problems such as false touch, and it is not suitable for application scenarios that frequently contact the outside world. When the third sensing part 300 includes the elastic fiber 420, as the elastic fiber 420 changes from thin to thick, the capacitance change amount of the third sensing part 300 under different pressures gradually decreases, and the sensitivity is moderate, so that a larger range of pressures can be sensed, and the applicable range is wider.

[0106] It can be understood that the forms of the above-mentioned first braided body and the second braided body are only exemplary descriptions of the technical solutions of the present application, and those skilled in the art can make other deformations. For example, in this embodiment, the first sensing part 100 is an example of the first braided body, and the second sensing part 200 and the third sensing part 300 are examples of the second braided body. In other embodiments, the fabric 10 may include the second sensing part 200 and the third sensing part 300. The second sensing part 200 may be an example of the first braided body. The third sensing part 300 is an example of the second braided body. The braided material of the third sensing part 300 includes functional fibers different from those of the second sensing part 200 (for example, the elastic fiber 420), so that the compressibility of the third sensing part 300 is less than that of the second sensing part 200, to ensure the stability of sensing pressure information.

[0107] The exemplary structures of the sensing parts in the fabric 10 and the setting methods of the functional fibers therein will be introduced one by one below with reference to the drawings.

[0108] Continue to refer to Figure 5B and Figure 5C , in some embodiments of the present application, the first sensing part 100 includes a conductive layer 101. The conductive layer 101 is woven from conductive fibers 500.

[0109] Figure 8 shows an exemplary structure of another first sensing part 100 of the present application. As Figure 8 described, the first sensing part 100 may further include a conductive layer 101 and an insulating layer 102 stacked in the Z direction. Among them, the surface of the conductive layer 101 forms a part of the outer surface of the fabric 10, and the surface of the insulating layer 102 forms a part of the inner surface of the fabric 10. That is to say, the conductive layer 101 is used to directly contact the user's skin, so as to realize the function of sensing physiological information. In some implementation manners, the insulating layer 102 may be woven from insulating fibers 600.

[0110] It can be understood that the present application does not limit the specific structure of the first sensing part 100, as long as it is ensured that the conductive layer 101 is in direct contact with the user's skin to enable the function of sensing physiological information.

[0111] Continue to refer to Figure 5B , the second sensing part 200 includes a conductive layer 201 and an insulating layer 202 stacked along the Z direction. Among them, along the Z direction, the surface of the conductive layer 201 forms a part of the inner surface of the fabric 10. The surface of the insulating layer 202 forms a part of the outer surface of the fabric 10. That is to say, the insulating layer 202 is used to be in direct contact with the user's skin, so as to avoid the user's fingers from affecting the generation of capacitance signals and ensure that the second sensing part 200 can normally sense touch information.

[0112] As mentioned above, in some embodiments of the present application, the second sensing part 200 may include thermoplastic fibers 410. The thermoplastic fibers 410 can reduce the elasticity of the second sensing part 200, thereby improving the stability of the second sensing part 200 in sensing touch information. Several exemplary setting methods of the thermoplastic fibers 410 in the second sensing part 200 will be introduced below with reference to the accompanying drawings.

[0113] In some embodiments of the present application, the conductive layer 201 is woven by the thermoplastic fibers 410 and the conductive fibers 500 together. The thermoplastic fibers 410 can limit the relative movement between adjacent conductive fibers 500 after heating and cooling, thereby effectively reducing the elasticity of the conductive layer 201.

[0114] It can be understood that there are various weaving methods between the thermoplastic fibers 410 and the conductive fibers 500 in the present application.

[0115] Figure 9 Shows a weaving schematic diagram of a kind of thermoplastic fiber 410 and conductive fiber 500 in an embodiment of the present application. Refer to Figure 9 , the thermoplastic fibers 410 can form a fiber group 700 together with the conductive fibers 500, and the fiber group 700 is woven to form the conductive layer 201.

[0116] In some of these implementation manners, the thermoplastic fibers 410 can be arranged in parallel with the conductive fibers 500 to jointly form a fiber group 700. That is to say, the thermoplastic fibers 410 and the conductive fibers 500 are in contact with each other, and the extension trajectory of the thermoplastic fibers 410 is substantially the same as that of the conductive fibers 500.

[0117] In some other implementation manners, the thermoplastic fibers 410 can also be wound around the conductive fibers 500 to be integrated, so as to jointly form a fiber group 700. For example, Figure 10A and Figure 10BThe figure shows a schematic diagram of the winding of several thermoplastic fibers 410 and conductive fibers 500 in the embodiments of the present application. As Figure 10A shown, the conductive fiber 500 can be used as the core yarn, and then the thermoplastic fiber 410 is helically wound around the outer periphery of the conductive fiber 500, thereby forming a fiber group 700. As Figure 10B shown, the thermoplastic fiber 410 and the conductive fiber 500 can also be helically wound with each other to form a fiber group 700 in a structure similar to a twist.

[0118] It can be understood that the above Figure 10A and Figure 10B only show some schemes of the winding of the thermoplastic fiber 410 and the conductive fiber 500, and do not constitute a specific limitation on the implementation manner of the present application.

[0119] Figure 11 The figure shows a schematic diagram of the weaving of another thermoplastic fiber 410 and conductive fiber 500 in the embodiments of the present application. Referring to Figure 11 , in some other embodiments of the present application, the thermoplastic fiber 410 and the conductive fiber 500 can be alternately arranged and woven to form a conductive layer 201. For example Figure 11 shown, the conductive layer 201 includes four rows of mutually woven fibers. Among them, the first row and the third row are thermoplastic fibers 410, and the second row and the fourth row are conductive fibers 500.

[0120] It can be understood that the area where the conductive fibers 500 of the above conductive layer 201 are located will form a conductive area, so that the second sensing part 200 can sense touch information. Different distribution forms of the conductive fibers 500 will form different numbers of conductive areas, and different numbers of conductive areas can realize different touch sensing functions.

[0121] In some embodiments of the present application, the conductive layer 201 may include a conductive area. Figure 12 The figure shows a schematic diagram of the conductive layer 201 including a conductive area 2011 in the embodiments of the present application. Referring to Figure 12 and combining Figure 9 , the adjacent conductive fibers 500 are electrically connected to each other and are not connected by insulating fibers (for example, thermoplastic fibers 410 or insulating fibers 600). That is, the conductive fibers 500 of the conductive layer 201 form a conductive area 2011. When the user's finger is placed at a position corresponding to the conductive area 2011 in the insulating layer (not shown), the amplitude of the capacitance signal of the conductive area 2011 will increase, so that touch information such as clicks (for example, single clicks, double clicks) and long presses can be recognized.

[0122] In some other embodiments of the present application, the conductive layer 201 may include a plurality of conductive areas to be able to sense more touch information, thereby further expanding the scope of application.

[0123] Specifically, Figure 13A FIG. 1 shows an exemplary arrangement mode one of a plurality of conductive regions 2011 in the conductive layer 201 in an embodiment of the present application. Refer to Figure 13A , the plurality of conductive regions 2011 of the conductive layer 201 can be arranged in a one-dimensional array. That is, the plurality of conductive regions 2011 are arranged at intervals along the same direction (for example, Figure 13A the X direction shown in FIG. 1). Wherein, the X direction is perpendicular to the Z direction (that is, Figure 13A the direction perpendicular to the paper surface in FIG. 1)

[0124] In this way, the second sensing part 200 can also sense a sliding touch in a one-dimensional direction. Figure 13B FIG. 2 shows an exemplary process in which the second sensing part 200 senses a sliding touch in a one-dimensional direction. Refer to Figure 13A and in combination with Figure 13B , when the user's finger is at point P1, the amplitude of the capacitance signal of the conductive region 2011a is larger than that of the capacitance signals of other conductive regions. During the process of the user's finger sliding from point P1 to point P2, the amplitude of the capacitance signal of the conductive region 2011a gradually decreases, and the amplitude of the capacitance signal of the conductive region 2011b gradually increases. The second sensing part 200 can sense the sliding of the user's finger in the X direction based on the change in the capacitance amplitudes of the conductive region 2011a and the conductive region 2011b.

[0125] Figure 14 FIG. 3 shows an exemplary arrangement mode two of a plurality of conductive regions 2011 in the conductive layer 201 in an embodiment of the present application. Refer to Figure 14 , the plurality of conductive regions 2011 of the conductive layer 201 can be arranged in a two-dimensional array. That is, the plurality of conductive regions 2011 are arranged at intervals along the row direction (for example, Figure 14 the Y direction shown in FIG. 3) and the column direction (for example, Figure 14 the X direction shown in FIG. 3) respectively. Exemplarily, the X direction, the Y direction and the Z direction (that is, Figure 14 the direction perpendicular to the paper surface in FIG. 3) are perpendicular to each other pairwise.

[0126] In this way, the second sensing part 200 can also sense a sliding touch in a two-dimensional direction. And, based on the sensing of the sliding touch in the two-dimensional direction, the coordinates of the contact point between the user and the second sensing part 200 in the X direction and the Y direction can be obtained, so that the second sensing part 200 can sense the specific position of the user's finger touch. Among them, the specific principle of the second sensing part 200 sensing the sliding in the two-dimensional direction is substantially the same as the specific principle of the second sensing part 200 sensing the sliding in the one-dimensional direction above. Specifically, reference can be made to Figure 13A and Figure 13B and their related descriptions, which will not be elaborated here.

[0127] The following introduces several implementation methods of two-dimensional array arrangements of multiple conductive regions 2011 in conjunction with the accompanying drawings.

[0128] Figure 15 A schematic structural diagram of a two-dimensional array distribution of the conductive region 2011 in an embodiment of the present application is shown. Refer to Figure 15 and in conjunction with Figure 14 , in some of the implementation methods, the conductive layer 201 of the second sensing part 200 is a single-layer woven structure formed by thermoplastic fibers 410 and conductive fibers 500. Therefore, the conductive region 2011 is a single-layer structure, and each conductive region 2011 is similar to a dot shape and is arranged in the direction of a two-dimensional array, thereby forming a dot matrix type self-capacitance region.

[0129] Figure 16A and Figure 16B A schematic structural diagram of another two-dimensional distribution of the conductive region 2011 in an embodiment of the present application is shown. Among them, Figure 16A is a top view of the conductive region 2011, Figure 16B is an exploded view of the conductive region 2011.

[0130] Refer to Figure 16A and Figure 16B and in conjunction with Figure 5B , in some alternative implementation methods, the conductive layer 201 of the second sensing part 200 can be a double-layer woven structure formed by thermoplastic fibers 410 and conductive fibers 500. Therefore, the conductive region 2011 is a double-layer structure, and each layer can be arranged in a one-dimensional array manner, and the arrangement directions of the two layers are perpendicular to each other, thereby finally forming multiple conductive regions 2011 arranged in a two-dimensional array manner.

[0131] Specifically, the conductive layer 201 of the second sensing part 200 includes two sub-conductive layers, namely a first sub-conductive layer 201a and a second sub-conductive layer 201b. The first sub-conductive layer 201a and the second sub-conductive layer 201b are stacked along the Z direction. Among them, the first sub-conductive layer 201a includes multiple first sub-conductive regions 2011a. The multiple first sub-conductive regions 2011a are respectively in a long strip shape and are arranged in a one-dimensional array manner along the Y direction. The second sub-conductive layer 201b includes multiple second sub-conductive regions 2011b. The multiple second sub-conductive regions 2011b are respectively in a long strip shape and are arranged in a one-dimensional array manner along the X direction.

[0132] The first sub-conductive region 2011a and the second sub-conductive region 2011b have a plurality of overlapping portions in the Z direction. For example, a plurality of first portions S1 of the first sub-conductive region 2011a and a plurality of second portions S2 of the second sub-conductive region 2011b. Each first portion S1 and the second portion S2 overlapping with it in the Z direction can jointly form a conductive region 2011. Since the plurality of first portions S1 and the plurality of second portions S2 are both distributed in a two-dimensional array manner, therefore, the plurality of conductive regions 2011 are also arranged in a two-dimensional array manner.

[0133] It can be understood that the conductive region 2011 of the above double-layer structure is a mutual inductance capacitance region. Among them, any one of the first sub-conductive region 2011a and the second sub-conductive region 2011b can be used as a transmitting electrode for emitting an electric field signal, and the other can be used as a receiving electrode for receiving the electric field signal emitted by the transmitting electrode, thereby realizing the perception of touch information.

[0134] In some embodiments of the present application, both the first sub-conductive layer 201a and the second sub-conductive layer 201b of the conductive layer 201 are jointly woven by thermoplastic fibers 410 and conductive fibers 500, so as to further reduce the elasticity of the conductive layer 201. In other embodiments, any one of the sub-conductive layers in the conductive layer 201 is jointly woven by thermoplastic fibers 410 and conductive fibers 500. For example, the first sub-conductive layer 201a is jointly woven by thermoplastic fibers 410 and conductive fibers 500, and the second sub-conductive layer 201b is woven by conductive fibers 500.

[0135] Figure 17 An exemplary structure of the insulating layer 202 in the second sensing portion 200 in the embodiments of the present application is shown. Refer to Figure 17 , in some embodiments of the present application, the insulating layer 202 is jointly woven by thermoplastic fibers 410 and insulating fibers 600. The thermoplastic fibers 410 can limit the relative movement between adjacent insulating fibers 600 after heating and cooling, thereby effectively reducing the elasticity of the insulating layer 202.

[0136] Among them, the weaving method between the thermoplastic fibers 410 and the insulating fibers 600 is substantially the same as the weaving method between the above-mentioned thermoplastic fibers 410 and the conductive fibers 500. Therefore, reference can be made to the relevant description of the weaving method of the thermoplastic fibers 410 and the conductive fibers 500 above, and details will not be described here.

[0137] It can be understood that the above embodiments are only exemplified by the second sensing part 200 including the stacked conductive layer 201 and insulating layer 202. In other embodiments, the second sensing part 200 may also include the conductive layer 201 and not include the insulating layer 202. The conductive layer 201 is woven by the thermoplastic fiber 410 and the conductive fiber 500 together. Among them, the thermoplastic fiber 410 wraps around the outer periphery of the conductive fiber 500 and forms a fiber group 700 together with the conductive fiber 500, and the fiber group 700 is woven to form the conductive layer 201. Exemplarily, Figure 18 shows a cross-sectional schematic diagram of the fiber group 700 in some other embodiments of the present application. Refer to Figure 18 , since the thermoplastic fiber 410 wraps around the outer periphery of the conductive fiber 500, after the fiber group 700 is woven to form a conductive layer (not shown), the user's finger contacts the thermoplastic fiber 410 and does not contact the conductive fiber 500, so it will not affect the generation of the capacitance signal, thus ensuring that the second sensing part 200 can normally sense touch information.

[0138] Continue to refer to Figure 5B , in some embodiments of the present application, the third sensing part 300 includes two conductive layers stacked along the Z direction, namely the first conductive layer 301a and the second conductive layer 301b. An insulating layer 302 is provided between the first conductive layer 301a and the second conductive layer 301b. Among them, along the Z direction, the surface of any one of the first conductive layer 301a and the second conductive layer 301b forms a part of the inner surface of the fabric 10, and the surface of the other layer forms a part of the outer surface of the fabric 10. That is to say, the user can contact any one of the first conductive layer 301a and the second conductive layer 301b. The first conductive layer 301a and the second conductive layer 301b can form a planar capacitor to realize the perception of pressure.

[0139] As mentioned above, in some embodiments of the present application, the third sensing part 300 may include the thermoplastic fiber 410. The thermoplastic fiber 410 can make the third sensing part 300 have less elasticity to ensure the stability of sensing pressure information.

[0140] In some embodiments of the present application, the first conductive layer 301a is woven by the thermoplastic fiber 410 and the conductive fiber 500 together. The thermoplastic fiber 410 can limit the relative movement between adjacent conductive fibers 500 after heating and cooling, thereby effectively reducing the elasticity of the first conductive layer 301a.

[0141] In some embodiments of the present application, the second conductive layer 301b can also be formed by co-weaving thermoplastic fibers 410 and conductive fibers 500. The thermoplastic fibers 410 can limit the relative movement between adjacent conductive fibers 500 after heating and cooling, thereby effectively reducing the elasticity of the second conductive layer 301b.

[0142] Among them, the weaving method between the thermoplastic fibers 410 and the conductive fibers 500 in the first conductive layer 301a and the second conductive layer 301b is substantially the same as the weaving method between the thermoplastic fibers 410 and the conductive fibers 500 in the above-mentioned conductive layer 201. For specific details, reference can be made to the relevant description of the conductive layer 201 above, and details will not be elaborated here.

[0143] It can be understood that conductive regions will also be formed in the regions where the conductive fibers 500 in the first conductive layer 301a and the second conductive layer 301b are located, so that the third sensing part 300 can sense different pressure information. Different distribution forms of the conductive fibers 500 will form different numbers of conductive regions, and different numbers of conductive regions can form different forms of planar capacitors, thereby realizing different pressure sensing functions.

[0144] Figure 19 An exemplary setting method of the conductive regions in the first conductive layer 301a and the second conductive layer 301b in the embodiments of the present application is shown. As Figure 19 shown, in some embodiments of the present application, the first conductive layer 301a includes a first conductive region 3011a. The second conductive layer 301b includes a second conductive region 3011b. The first conductive region 3011a and the second conductive region 3011b are arranged opposite to each other in the Z direction, thereby jointly forming a planar capacitor that can be used to sense the pressure magnitude at a single position.

[0145] In other embodiments of the present application, the number of the first conductive regions 3011a and the second conductive regions 3011b can be multiple respectively, so as to jointly form multiple planar capacitors, thereby being able to sense the pressure magnitudes at multiple positions.

[0146] In some implementation manners, the arrangement manners of the multiple first conductive regions 3011a and the multiple second conductive regions 3011b can be the same. For example, Figure 20 An exemplary setting method of another conductive region in the first conductive layer 301a and the second conductive layer 301b in the embodiments of the present application is shown. As Figure 20As shown, multiple first conductive regions 3011a and multiple second conductive regions 3011b are both arranged in a two-dimensional array, and the arrangement directions are the same. The multiple first conductive regions 3011a and the multiple second conductive regions 3011b correspond to each other one by one. Along the Z direction, the projections of each first conductive region 3011a and the corresponding second conductive region 3011b on the insulating layer 302 coincide with each other, thereby jointly forming a capacitor. In this way, the third sensing part 300 can have multiple capacitors arranged in a two-dimensional array, so that the pressure magnitudes at multiple positions in the two-dimensional direction can be sensed.

[0147] For another example, multiple first conductive regions 3011a and multiple second conductive regions 3011b can also be arranged in a one-dimensional array, and the arrangement directions are the same. The multiple first conductive regions 3011a and the multiple second conductive regions 3011b correspond to each other one by one. Along the Z direction, the projections of each first conductive region 3011a and the corresponding second conductive region 3011b on the insulating layer 302 coincide with each other, thereby jointly forming a capacitor. In this way, the third sensing part 300 can have multiple capacitors arranged in a one-dimensional array, so that the pressure magnitudes at multiple positions in the one-dimensional direction can be sensed.

[0148] In some other implementation manners, the arrangement manners of the multiple first conductive regions 3011a and the multiple second conductive regions 3011b can be different. For example, the multiple first conductive regions 3011a and the multiple second conductive regions 3011b can both be arranged in a one-dimensional array, and the arrangement directions are perpendicular to each other, so that the multiple capacitors finally formed are arranged in a two-dimensional array, and the specific implementation manner is substantially the same as the implementation manner of forming the multiple conductive regions 2011 arranged in a two-dimensional array above. Specifically, reference can be made to Figure 16A and Figure 16B and its related descriptions, which will not be elaborated here.

[0149] As described above, in some embodiments of the present application, the third sensing part 300 can include an elastic fiber 420. The elastic fiber 420 can reduce the compressibility of the third sensing part 300, so that the third sensing part 300 can sense a larger range of pressures. In addition, by selecting different elastic fibers 420, the third sensing part 300 can have different compressibilities, so as to meet the pressure sensing requirements in different application scenarios.

[0150] Specifically, Figure 21 shows an exemplary structure of the insulating layer 302 in the third sensing part 300 in the embodiment of the present application. Refer to Figure 21, in some embodiments of the present application, the insulating layer 302 is woven by the elastic fiber 420 and the insulating fiber 600 together. The elastic fiber 420 can effectively enhance the elasticity of the insulating layer 302, thereby playing a role in elastically supporting the first conductive layer 301a and the second conductive layer 301b, and further making the third sensing part 300 less compressible, and the third sensing part 300 can withstand a larger range of pressures.

[0151] Among them, the weaving method between the elastic fiber 420 and the insulating fiber 600 is substantially the same as the weaving method between the above-mentioned thermoplastic fiber 410 and the conductive fiber 500. Therefore, the relevant description about the weaving method of the thermoplastic fiber 410 and the conductive fiber 500 above can be referred to, and it will not be elaborated here.

[0152] In some embodiments of the present application, the weaving structure 20 can be woven by the insulating fiber 600, so as to prevent the first sensing part 100, the second sensing part 200 and the third sensing part 300 from being electrically connected to each other, and ensure that the first sensing part 100, the second sensing part 200 and the third sensing part 300 can work normally.

[0153] In some embodiments of the present application, the thermoplastic fiber 410 can be any one of polyamide fiber, polyester fiber or polypropylene fiber.

[0154] In some embodiments of the present application, the material of the elastic fiber 420 can be any one of polyurethane, polyacrylate or polyester.

[0155] In some embodiments of the present application, the conductive fiber 500 can be any one of carbonaceous fiber, copper wire, silver wire, stainless steel wire or natural fiber or synthetic chemical fiber coated with a conductive material. Among them, the conductive material can be gold, silver, silver nanowire or copper.

[0156] In some embodiments of the present application, the insulating fiber 600 can be any one of cotton fiber, wool fiber, linen fiber, silk fiber, polyester fiber, spandex fiber, acrylic fiber, aramid fiber, polyamide fiber, acrylic fiber, polypropylene fiber, polyester fiber or nylon fiber.

[0157] The above describes the embodiments of the present application through specific examples, and those skilled in the art can easily understand other advantages and effects of the present application from the content disclosed in this specification. Although the description of the present application will be introduced in combination with some embodiments, this does not mean that the features of this application are limited to this embodiment. On the contrary, the purpose of introducing the application in combination with the embodiment is to cover other alternatives or modifications that may extend based on the claims of the present application. The present application can also be implemented without using these details. In addition, in order to avoid confusion or obscuring the key points of the present application, some specific details are omitted in the description.
