TECHNICAL FIELD
[0001] The present application relates to the field of clothing, in particular to a self-adaptive clothing, a manufacturing process and a control method. BACKGROUND
[0002] The core adjustment mechanism of traditional trousers relies on the inherent elasticity of the fabric or physical elastic bands, which is a static and passive solution that cannot meet the dynamic mechanical needs of the human body in complex daily activities. The fundamental defect lies in the lack of intelligent dynamic adjustment capability: when the human body changes from sitting to walking, running or deep squatting, the girth, tension and required support strength of the hip, knee joint, thigh muscle group and waist and abdomen will change significantly. For example, the waist needs to be moderately relaxed to avoid compression when sitting, while the thigh and waist need stronger wrapping and support to stabilize the muscles and reduce shaking when running at high speed. The fixed tightness cannot adapt to such differences, leading to a dilemma: designing too tight to ensure fit during exercise will cause compression discomfort when sitting; designing loose for static comfort will not provide effective support during exercise, and even cause the trousers to slide down, affecting exercise performance and experience.
[0003] Although intelligent clothing technology attempts to solve this problem, its development is currently extremely uneven. Most so-called "smart" products still highly focus on the integration of data collection functions, such as using flexible strain sensors to monitor joint bending angles, or using inertial measurement units (IMU) to identify motion states (such as walking, running, and standing still). However, this only realizes the "detection" link in the closed-loop system. The key "adjustment" link is severely lagging behind and fails to form an effective linkage with it. Existing exploratory adjustment schemes, such as air bag inflation based on pneumatic pumps, thermal contraction using shape memory alloys (SMA), or tightening cables through micro motors, all face insurmountable practical bottlenecks: pneumatic systems are bulky, noisy and slow to respond; SMA has high energy consumption, limited contraction rate and heat; micro motors have a fundamental contradiction between rigid structure and clothing flexibility, making it difficult to integrate comfortably into the fabric.
[0004] Therefore, the current technical intelligent trousers concept fails to go beyond the paradigm of traditional design, only providing information at the data level, but cannot adjust the fit and support of the trousers in real time and automatically at the physical level. In addition, poor system integration (conflict between hard elements and soft textiles), short energy endurance, high cost and durability issues such as washability, together hinder its transition from laboratory prototypes to large-scale commercial applications, making users unable to truly experience the revolutionary comfort improvement brought by self-adaptive clothing.

DETAILED DESCRIPTION
[0023] The technical solution of the application will be further described below by combining the drawings and through the specific embodiment.
[0024] The adaptive clothing 4 provided by the application comprises an outer layer fabric 6, an inner layer fabric 8, an electric control component 2 and a middle layer 7, wherein the middle layer 7 is arranged at part or all of the outer layer fabric 6 and the inner layer fabric 8, and the middle layer 7 comprises, from inside to outside, a sensing layer 5 for sensing the pressure condition of the wearer and an adjusting layer 13 for adjusting the tension or pressure, wherein the side close to the skin is inside and the side far from the skin is outside. The adjusting layer 13 and the sensing layer 5 are electrically connected with the electric control component 2 through the electrode yarn 10. Such a structure enables the clothing 4 to adaptively adjust according to the pressure condition of the wearer, thereby improving the comfort and functionality of the wearer.
[0025] The electric control assembly 2 is arranged at the back of the waist or the side of the waist, has a volume less than 20 g, and can be detached and replaced. The electric control assembly 2 comprises a controller and a battery, the controller can adopt HWD12B16GA4 of Chengdu Huaweimicro, and the electric control assembly 2 further comprises a wireless communication module electrically connected with the controller. The wireless communication module can adopt Insight SIP ISP4580, which is a multi-sensor integrating LoRa and Bluetooth 5.0 functions, and the system can be connected with other terminals (such as a mobile phone APP) through the wireless module (Bluetooth / LoRa) to realize remote monitoring.
[0026] The sensing layer 5 is formed by knitting the sensing yarn 9 into a grid; the sensing yarn 9 is a yarn with electric conductivity or sensing performance.
[0027] The sensing yarn 9 can be an electrically conductive yarn, or a piezoresistive or capacitive sensing yarn. The electrically conductive yarn is formed by combining an electrically conductive material with a traditional textile fiber, such as mixing extremely fine metal fibers of stainless steel, silver, copper, etc. with traditional fibers such as cotton, polyester, nylon, etc. to form a blend, or plating a layer of metal (such as silver, copper) on the surface of a polyester, nylon, etc. base yarn to make it conductive. Such as silver-plated conductive yarn and Thunderon conductive yarn on the market.
[0028] The yarn with sensing performance is a yarn that can perceive and respond to specific physical, chemical or biological stimuli (such as pressure, stretching, temperature, humidity, etc.) and convert them into measurable electrical signals, such as E-PT yarn.
[0029] The grid structure is formed by the knitting process, and this grid structure can more sensitively perceive changes in pressure. The grid density is higher at key positions such as the waist, hips, outer thighs, knees, etc., such as using a 5-10mm grid, which can more accurately perceive the pressure conditions of these important parts. The piezoresistive or capacitive sensing yarn 9 can also be replaced by other yarn materials with pressure sensing function to adapt to different application scenarios. The electrode yarn 10 and the sensing yarn 9 adopt a cross-over form to form a sensing node, the dew point at the node is aligned with the window 14 of the inner contact layer 12, and the effective conduction of the signal is ensured. The lead wire is arranged in the way of winding yarn → twisting → weaving, and the convergence point is made of a soft soldering pad (or an ultrasonic compression metal patch) with a thickness ≤0.2mm, which can ensure stable transmission of the signal and avoid affecting the overall thickness and comfort of the garment 4. The ultrathin flexible metalized cloth sheet can also be replaced by other flexible materials with conductive properties.
[0030] The sensing layer 5 can also form a mesh-shaped sensing network by the cross combination of the sensing yarn 9 and the electrode yarn 10 in other embodiments, which can comprehensively and accurately perceive the pressure condition of the wearer. When the pressure of each part of the wearer's body changes, the resistance or capacitance value of the sensing yarn 9 will change accordingly, and these changes are transmitted to the convergence point through the electrode yarn 10, and then transmitted to the electric control assembly 2 for processing and analysis.
[0031] The adjusting layer 13 includes wire type material and / or film type material. The wire type material includes SMA wire or EAP wire, which is arranged in the form of a wire bundle array along the circumference or longitudinal direction of the garment 4, and the distance between adjacent wires is between 20-30mm. The SMA wire has a shape memory function and will restore to a preset shape when heated to a certain temperature, thereby realizing the adjustment of tension; the EAP wire has an electrostrictive property and will deform after being electrified. Both of these materials can deform according to the control of the electric control assembly 2 to adjust the tension of the garment 4. The SMA wire or EAP wire can also be replaced by other materials with similar functions, such as certain shape memory polymers, etc. The film type material includes the film formed by the air bag 1. The sensing layer 5 is arranged at the edge of the air bag 1 or between adjacent air bags 1. The air bags 1 are provided with hoses 3 or flow guide grooves, and a micro air pump is arranged on the garment, which is connected with the valve on the air bag 1.
[0032] The combination logic of the adjusting layer 13 is to select wire type and / or film type material according to different adjustment requirements. When local tension adjustment is needed, the deformation of the SMA wire or EAP wire can be controlled by the electric control assembly 2; when local pressure adjustment is needed, the air bag 1 is inflated or deflated by the air pump. These two adjustment methods can be used alone or in combination to achieve more accurate and diversified adjustment effects.
[0033] An isolation layer 11 is also arranged inside the adjusting layer 13, which is a thin metalized fabric or conductive yarn net, used for electromagnetic / driving noise shielding, especially near the SMA / electric drive, and serves as a ground reference, with a thickness ≤0.2mm. The thin metalized fabric or conductive yarn net can also be replaced by other materials with electromagnetic shielding function. The function of the isolation layer 11 is to reduce the electromagnetic and driving noise generated during the adjustment process, which interferes with the sensing layer 5, and ensure the accuracy of the sensing data.
[0034] The inner side of the sensing layer 5 is also provided with a contact layer 12. The contact layer 12 is provided with a window 14 at the position of the adjusting layer (i.e. the wire type material and / or the film type material) or the local position of the electrode yarn 10 to maintain signal transmission. The thickness of the contact layer 12 is between 0.3-0.6mm. The contact layer 12 adopts a flexible sponge or a three-dimensional mesh which can reduce direct friction and has a buffering effect. The flexible sponge or the three-dimensional mesh can also be replaced with other materials with buffering and air permeability functions. The role of the contact layer 12 is to provide a buffering effect and protect the skin while ensuring the normal implementation of sensing and adjusting functions.
[0035] The pressure condition of the wearer is sensed in real time by the sensing layer 5, and the pressure signal is transmitted to the electric control assembly 2. The electric control assembly 2 analyzes and processes these signals according to a preset algorithm, judges the motion state and pressure demand of the wearer, and then issues corresponding control instructions to the adjusting layer 13. The adjusting layer 13 adjusts the tension or pressure according to the instructions to adapt to the needs of the wearer. At the same time, the isolation layer 11 can reduce the interference generated during the adjusting process, and the contact layer 12 can improve the comfort of the wearer. This structure and control mode effectively solve the problems of inaccurate sensing, inaccurate adjusting and poor comfort in the prior art, and improve the functionality and practicality of the garment 4.
[0036] Embodiment 1 Only the film type material is used in the adjusting layer 13, i.e. only the thin film formed by the air bags 1 is used to adjust the pressure of the garment 4. The film type includes the thin film formed by the air bags 1. Hoses 3 or flow guide grooves are arranged between the air bags 1, and a gas pump is also included, which is arranged on the garment 4 and is connected to the valve on the air bag 1 through a magnetic interface or a side seam of the garment 4. The air bags 1 are inflated or deflated by the gas pump to realize the adjustment of the local pressure of the garment 4. The sensing layer 5 is arranged at the edge of the air bag 1 or between adjacent air bags 1 to avoid the direct compression interference of the air bag 1 on the sensor and ensure the accuracy of sensing. The thin film formed by the air bag 1 can also be made of other materials with flexibility and sealing properties.
[0037] The air bags 1 are inflated or deflated by the gas pump to realize the adjustment of the local pressure or tension of the garment 4. The sensing layer 5 is arranged at the edge of the air bag 1 or between adjacent air bags 1 to accurately sense the pressure change and transmit the signal to the electric control assembly 2. The electric control assembly 2 controls the operation of the gas pump according to the sensing signal to realize the accurate adjustment of the pressure. This structure is relatively simple and has a low cost, which is suitable for scenes with small tension adjustment demand. It also solves the problems of inaccurate pressure adjustment and interference in the prior art, and improves the adaptability and practicality of the garment 4.
[0038] Embodiment 2 The difference between this embodiment and embodiment 1 is that the adjusting layer 13 only uses wire type, specifically SMA (shape memory alloy wire).
[0039] SMA wire: through the phase change shrinkage by electric heating, it can provide larger shrinkage force and structural support, but the response speed is slow, the adjusting frequency is limited, and it is suitable for large range tension adjustment (for example, waist circumference tightening, posture support).
[0040] The electric control component 2 in the garment 4 judges according to the pressure signal collected by the sensing layer 5 in real time, when it is detected that the wearer needs to adjust, the SMA wire array is driven to generate shape memory effect by electric heating, to realize larger range, slower speed structural tightening or loosening, to establish the reference tension; Embodiment 3 The difference between this embodiment and embodiment 2 is that the adjusting layer 13 only uses EAP wire (electrostrictive fiber) as the main fabric of the adjusting layer 13.
[0041] EAP wire: under the action of electric field, it can produce faster deformation, the response speed is fast, but the driving force is small, and it is suitable for fast fine adjustment or comfort adjustment (for example, fit, pressure balance).
[0042] The electric control component 2 in the garment 4 judges according to the pressure signal collected by the sensing layer 5 in real time, when it is detected that the wearer needs to adjust, then the EAP wire or film is driven to produce fast and subtle deformation by applying electric field, to fine tune and compensate the local pressure, so as to realize the self-adaptive adjustment mechanism combining coarse adjustment and fine adjustment, and giving consideration to stability and comfort.
[0043] Embodiment 4 The difference between this embodiment and the foregoing embodiments is that the adjusting layer 13 uses air bag 1 combined with wire (SMA wire or EAP wire), after the electric control component 2 in the garment 4 receives the pressure signal fed back by the sensing layer 5, first uses the wire (such as SMA or EAP) to perform structural contraction or expansion, to form the basic tension and contour support; on this basis, the air bag 1 is inflated and deflated through the control of the air pump and valve, to realize fast local pressure adjustment and buffering. The wire is responsible for providing long-term and stable tension framework, and the air bag is used for dynamic response and flexible compensation, which are complementary to each other under the coordination of the control system, so that the garment can maintain overall support and adjust the pressure at different positions at any time, so as to achieve the comprehensive effect of stability, comfort and self-adaptation.
[0044] Embodiment 5 The manufacturing process of the self-adaptive garment 4 provided in the embodiment of the application includes the following steps: S1, weaving The fabric is woven, during which conductive or sensing yarns are embedded into the fabric along a predetermined path to form the yarn network of sensing layer 5. In this step, a suitable fabric substrate material can be selected, such as common natural fiber fabrics like cotton and linen, or synthetic fiber fabrics like polyester and nylon. During the weaving process, a knitting or braiding technique is used to embed the conductive or sensing yarns (i.e., sensing yarns 9) into the fabric substrate along a designed path, forming a mesh-like sensing network. The tools used can be knitting machines or braiding machines; the yarn tension and braiding density need to be carefully controlled to ensure the uniformity and stability of the sensing network.
[0045] S2, Set adjustment layer 13 S21. Embedded wire type material SMA or EAP yarns, which are thread-type materials, are interwoven between fabrics and secured using high-tensile-strength adhesive tape or sewing to prevent breakage or displacement due to localized stress. In this step, the SMA or EAP yarns are carefully interwoven into the predetermined positions on the fabric and then secured using high-tensile-strength adhesive tape or sewing. It is crucial to ensure a firm fixation to prevent breakage or displacement of the yarns due to localized stress during use.
[0046] S23. Install airbag 1 The airbag 1 is laminated to the fabric, and its edges are fixed to the fabric using hot pressing or laser welding to form an independent airbag cavity. In this step, a suitable airbag 1 material, such as a TPU film, is selected and laminated to the fabric substrate where the sensor network has already been formed. Then, using hot pressing or laser welding equipment, the edges of the airbag 1 are heated or irradiated with a laser to firmly bond it to the fabric, forming an independent airbag cavity. Careful control of the temperature, pressure, and time of hot pressing, or the power and irradiation time of the laser, is necessary to ensure the airbag 1's sealing and stability.
[0047] S3. A signal busbar area is set on the fabric, using a metallized fabric sheet or a flexible flat cable pad as the lead-out port. The end of the sensing yarn 9 is fixed to the lead-out port by ultrasonic pressing or conductive adhesive. In this step, a suitable signal busbar area is determined on the fabric, and then the metallized fabric sheet or flexible flat cable pad is placed in that area as the lead-out port. The sensing yarn 9 and the adjustment layer are connected to the electrode yarn 10 using ultrasonic pressing equipment or by applying conductive adhesive. The electrode yarn 10 is connected to the lead-out port, and the lead-out port is electrically connected to the electronic control component 2. This ensures stable signal transmission.
[0048] The application combines the sensing network, the air bag 1 and the wire material type material organically through reasonable preparation steps to form the self-adaptive adjusting function clothing 4. Each step has its specific function and requirement, and the process parameters and operation process of each step are strictly controlled to ensure the quality and performance of the clothing 4. The manufacturing process can effectively realize the batch production of the clothing 4, improve the production efficiency and product quality, solve the problems of complex preparation process, unstable quality and the like of the intelligent clothing 4 in the prior art, and promote the industrialized development of the self-adaptive clothing 4.
[0049] Embodiment 6 The control method of the self-adaptive clothing 4 provided by the embodiment of the application includes the following steps. A1, set the sensing and adjusting to be alternately executed in the electric control assembly 2, and each cycle is a ms, wherein the sensing time is a / 4 ms and the adjusting time is 3a / 4 ms. In this step, according to the actual application scene and performance requirement of the clothing 4, the appropriate cycle time a is set in the program of the electric control assembly 2. For example, when applied to the daily wearing scene, a can be set to 200 ms, so that the sensing time is 50 ms and the adjusting time is 150 ms. This alternating execution mode can avoid the interference between the sensing and adjusting processes, and improve the stability and accuracy of the system.
[0050] A2, during the sensing period, the adjusting power supply is turned off or the adjusting power is reduced, and the sensing assembly arranged in the adjusting layer 13 is used to collect the adjusting layer 13 cavity pressure signal or fabric strain signal. During the sensing period, in order to avoid the interference of the action of the adjusting layer 13 on the sensing signal, the power supply of the adjusting layer 13 is turned off or the power thereof is reduced. Then the sensing assembly arranged in the adjusting layer 13, such as the piezoresistive or capacitive sensing yarn 9, is used to collect the pressure signal of the adjusting layer 13 cavity or the strain signal of the fabric. These signals can reflect the pressure and tension change conditions of each part of the wearer's body.
[0051] A3, during the adjusting period, the operation of driving the adjusting layer 13 is performed according to the sensing information. The electric control assembly 2 analyzes and processes the signals collected during the sensing period to judge the motion state and pressure demand of the wearer. Then according to the preset algorithm, the corresponding control instruction is sent to the adjusting layer 13 to drive the adjusting layer 13 to adjust the tension or pressure. For example, if the sensing signal shows that the wearer is in a running state, the electric control assembly 2 will control the adjusting layer 13 to increase the wrapping force of the thighs and the waist.
[0052] Embodiment 7 In the sensing period of step A2, the real-time pressure signal detected by the sensor is compared with the preset reference pressure value to obtain a deviation signal. The real-time pressure signal detected by the sensor is compared with the preset reference pressure value, and the difference between the two is calculated to obtain the deviation signal. The preset reference pressure value is a standard pressure value preset according to different motion states and human body needs.
[0053] The pressure or tension of the adjustment layer 13 is adjusted according to the deviation signal obtained by the above steps to maintain the target level. The control component 2 adjusts the control instruction sent to the adjustment layer 13 according to the size and direction of the deviation signal, and adjusts the pressure or tension of the adjustment layer 13 accordingly. If the deviation signal is positive, indicating that the actual pressure is greater than the reference pressure, the control component 2 will control the adjustment layer 13 to reduce the pressure; if the deviation signal is negative, indicating that the actual pressure is less than the reference pressure, the control component 2 will control the adjustment layer 13 to increase the pressure, so that the pressure is maintained at the target level.
[0054] The method for obtaining the deviation signal is to establish an action reference template of the adjustment layer 13, and the template is a standard pressure change curve caused after adjustment. In the running process, the real-time collected signal is compared with the reference template to obtain the true physiological pressure change signal by deducting the known motion interference. In the system initialization stage, the reference template of the adjustment layer 13 action, i.e. the standard pressure change curve caused after adjustment, is established through experiment and data analysis. In the running process of the garment 4, the real-time collected pressure signal is compared with the reference template to identify the pressure change part caused by the adjustment layer 13 action, and the pressure change part is deducted from the real-time signal, so as to obtain the true physiological pressure change signal, which can reduce the interference of the adjustment layer 13 action on the sensing signal and improve the sensing accuracy.
[0055] According to the true physiological pressure change signal obtained in the foregoing step, the adjustment intensity and duration are further adjusted to realize real-time adaptive regulation and control of the body fit, support force or pressure distribution. The control component 2 further optimizes the control instruction sent to the adjustment layer 13 according to the obtained true physiological pressure change signal, and adjusts the adjustment intensity and duration of the adjustment layer 13. If the true physiological pressure change signal shows that the pressure change of a certain part is large, the control component 2 will correspondingly increase the adjustment intensity or prolong the adjustment time of the part to realize real-time adaptive regulation and control of the body fit, support force and pressure distribution, and improve the comfort and functionality of wearing.
[0056] By setting the cycle of alternately executing sensing and adjusting, and a series of signal acquisition, comparison and adjustment steps, precise control of the adaptive garment 4 is achieved. During sensing, accurate pressure signals are collected, avoiding interference from the adjustment layer 13; during adjustment, precise adjustment is carried out according to the sensing signals, while by establishing a reference template to subtract known interference, the true physiological pressure change signal is obtained, further optimizing the adjustment effect. This control method can effectively improve the adaptive ability of the garment 4, meet the needs of the wearer in different scenarios, solve the problems of inaccurate control and untimely adjustment of the existing intelligent garment 4, and improve the performance and user experience of the adaptive garment 4.
