Description

Technical Field

[0001] This invention relates to the field of smart underwear, specifically to a smart human body monitoring underwear. Background Technology

[0002] As living standards improve, people are paying more and more attention to their health. Driven by this demand, more and more wearable health monitoring devices are entering people's lives, monitoring users' body parameters in real time and managing their health status. Because women's underwear generally uses elastic bands that fit close to the skin, it is the optimal carrier for sensors monitoring women's health. Health sensors placed on smart underwear can more easily acquire relevant body data with higher accuracy.

[0003] For example, Chinese patent document CN108576952B discloses an underwear capable of monitoring breast cancer lesions, comprising a connecting strap, a cup, and a monitoring system for securing the monitoring plate. This patent utilizes a smart chip embedded within the smart underwear, employing pressure and temperature sensors to monitor minute metabolic temperature changes caused by cancer cells, thereby enabling the detection of early-stage breast cancer. This approach provides a novel medium for health monitoring.

[0004] However, the core focus of this patent, as well as some existing smart underwear, is the integration of sensing functions. Some existing smart underwear mainly rely on traditional elastic bands or simple buckle structures for their connecting straps and bra straps. This structure can only provide a static and fixed tightness. Once the size or buckle position selected by the user when wearing the underwear is determined, the binding force it provides is constant.

[0005] This kind of binding force cannot adapt to the dynamic changes of the human body. When the human body produces natural chest rise and fall and trunk size changes due to daily activities such as breathing, walking, and sitting, traditional elastic bands are either too tight, causing a feeling of constriction and pressure during activities, or too loose, causing the underwear to shift or the sensor to have poor contact with the skin, affecting the monitoring accuracy.

[0006] It's impossible to personalize the fit according to individual body shape and comfort needs, and it's also impossible to achieve a continuous and stable fit during activity. Therefore, how to create an adjustable bra that can both personalize the tightness to ensure accurate sensor detection and adapt to the dynamic changes of the human body is a technical problem that current smart bra technology urgently needs to solve. Summary of the Invention

[0007] The purpose of this invention is to provide an intelligent human body monitoring underwear to solve the above-mentioned problems. By rotating the polygonal column to adjust the pretension of the coil spring, it can match different personal preferences for tightness. When the human body fluctuates due to normal activities such as breathing, the coil spring can absorb and compensate for these subtle dimensional changes in real time through its own deformation and rebound, so that the adjustment band always maintains pretension to ensure the accuracy of sensor detection. It not only ensures personalized initial comfort, but also achieves continuous tightness during activities, as detailed below.

[0008] To achieve the above objectives, the present invention provides the following technical solution: The present invention provides an intelligent human body monitoring underwear, comprising an underwear body, a mounting shell and an adjustment frame. An adjustment strap is fixed to the bottom of the underwear body, and an adjustment frame rotatably disposed inside the mounting shell is provided between the two ends of the adjustment strap. The mounting housing contains a mounting plate. The adjusting frame has cranks fixed at both ends to connect to the adjusting belt. A coil spring is fixed to the top of the mounting plate. The outer end of the coil spring is connected to an adjacent crank to wind up the adjusting belt. A polygonal post is slidably provided on the top of the mounting housing. A fixing groove is opened in the middle of the polygonal post for the inner end of the coil spring to slide up and down therein. The top of the polygonal post is adapted to the opening on the top of the mounting housing. The top of the polygonal post is detachably connected to the mounting housing to adjust the preload of the coil spring and lock the angle of the polygonal post and the coil spring, so that the coil spring can maintain the preload after the adjusting belt is stretched to conform to the human body.

[0009] Using the aforementioned intelligent human body monitoring underwear, when initially wearing it or when adjusting the fit, first pull the polygonal column upwards to separate it from the polygonal groove on the top of the mounting shell. At this time, the inner end of the coil spring can rotate freely with the polygonal column. Then, according to the required fit, rotate the polygonal column. By utilizing its cooperation with the inner end of the coil spring, the coil spring is wound up, thereby adjusting the preload of the coil spring. After adjustment, push the polygonal column back into the polygonal groove on the top of the mounting shell. By utilizing the fit between the polygonal block on its top and the polygonal groove, the rotation angle of the polygonal column is locked, thereby fixing the preload of the coil spring. In this state, the adjustment strap can always maintain a constant preload when static or with small-amplitude movement, so that the underwear body fits the human body. When a user exhibits poor posture such as slouching or hunching, the adjustment belt is subjected to tensile force. This tensile force is transmitted to the connecting cylinder through the crank, driving it to rotate. Since the connecting cylinder is threadedly connected to the threaded column, and the rotation angle of the threaded column is locked by the polygonal column inserted into its polygonal opening, the rotation of the connecting cylinder is transformed into driving the threaded column to move downward along the mounting plate. As the threaded column moves downward, the protrusion fixed at its bottom protrudes from the through groove at the bottom of the mounting shell and gradually presses against the human skin, producing a noticeable tactile sensation as an immediate reminder, prompting the human body to adjust its posture. When the posture returns to normal, the tension of the adjustment belt decreases, and the winding force of the coil spring drives the adjustment belt and the protrusion to reset, thus deactivating the reminder. When a user performs dynamic activities such as walking and turning, the bending and twisting of the torso causes the elastic band in the middle of the adjustment belt to repeatedly stretch and rebound, resulting in dynamic changes in the spacing between the adjustment belts on both sides. When the spacing between the adjustment belts on both sides of the elastic band widens, the two sets of mounting pads fixed on the outer side of the adjustment belt are pulled, causing the sealing rod and sealing tube to move in opposite directions. The airbag draws in air through the air supply tube and shrinks. When the spacing narrows, the sealing rod and sealing tube move closer to each other, pushing air into the airbag. During this process, the return spring provides elasticity to the sealing rod, prompting it to respond and reset quickly. By dynamically adjusting the gas in the airbag, the flexible sensor inside can be made to fit the skin, effectively offsetting the gap between the skin and clothing caused by human movement, thus ensuring the continuity and accuracy of the flexible sensor's signal monitoring.

[0010] Preferably, the top of the mounting shell has a polygonal groove, and the top of the polygonal column has a polygonal block that matches the polygonal groove to lock the rotation angle of the polygonal column. The top of the polygonal block has a snap-fit ​​groove.

[0011] Preferably, the bottom of the mounting shell is provided with a through groove, and a connecting cylinder is rotatably arranged between the mounting plate and the through groove, with the bottom of the crank rod fixed to the outer wall of the connecting cylinder.

[0012] Preferably, the connecting cylinder has an internal thread and a threaded post is threadedly connected to it. The threaded post is slidably connected to the mounting plate. The threaded post has a polygonal opening in the middle that is adapted to the polygonal post. After the polygonal post descends into the polygonal opening, the rotation angle of the threaded post is locked. When the adjusting belt is stretched, it drives the crank and the connecting cylinder to rotate. The threaded post with the angle locked moves up and down through the threaded engagement. A protrusion is fixed at the bottom of the threaded post so that when the adjusting belt is stretched by human movement, it protrudes downward into the through groove to press against the skin.

[0013] Preferably, a fixing bracket is fixed to the inner wall of the top of the mounting housing, and the bottom of the fixing bracket is attached to the coil spring to suppress the range of motion of the coil spring.

[0014] Preferably, an airbag is fixed to the inner side of the adjustment belt, and a flexible sensor that conforms to the skin is provided on the inner side of the airbag. Air delivery tubes are fixed to both sides of the airbag, and a sealing tube is fixedly connected to the end of the air delivery tube. A sealing rod is slidably arranged inside the sealing tube, and a sealing block that slides and seals with the sealing tube is fixed to the end of the sealing rod. A sealing rod is slidably sealed inside the sealing tube. Mounting pads are fixed to the end of the sealing tube and the end of the sealing rod. The mounting pads are fixed to the outside of the adjustment belt in pairs.

[0015] Preferably, a return spring is sleeved in the middle of the sealing rod, with its two ends respectively abutting against the sealing block and the end of the sealing tube.

[0016] Preferably, multiple elastic bands are fixed in the middle of the adjustment band, and the mounting pads are located on the outer sides of the adjustment bands on both sides of the elastic bands. The elastic bands can stretch with human movement to expand or shrink the distance between the two adjustment bands. Each set of mounting pads moves with the adjustment band and pulls the sealing rod and sealing tube to move towards each other to adjust the air pressure in the airbag, so that the airbag contracts and expands with human movement to keep the flexible sensor in contact with the human body.

[0017] Preferably, the elastic bands at both ends of the adjusting belt are fixed with connecting bands, and the ends of the connecting bands are fixed with a storage band with a width smaller than that of the connecting band and the adjusting belt. The end of the storage band is opened and sleeved on the middle of the crank to connect the crank and the adjusting belt.

[0018] Preferably, an outwardly curved intercepting rod is fixed to the outer side of the middle section of the crank rod. The intercepting rod can restrict the position of the storage strap stored in the mounting housing. A fixing rod is fixed to the end face of the crank rod adjacent to the outer end of the coil spring to connect the coil spring and transmit power.

[0019] The beneficial effects are as follows: 1. This invention adjusts the preload of the coil spring by rotating the polygonal column to match different personal preferences for tightness. During the wearing process, when the human body fluctuates due to normal activities such as breathing, the coil spring can absorb and compensate for these subtle size changes in real time through its own deformation and rebound, so that the adjustment band always maintains preload to ensure the accuracy of sensor detection. This not only ensures personalized initial comfort, but also achieves continuous tightness during activities. 2. The airbag is connected to the sealing tube through the air supply tube and dynamically inhales or inflates during daily activities. It is always filled between the sensor and the skin, pressing the flexible sensor to maintain continuous and stable contact with the skin, reducing problems such as signal loss due to poor contact, and ensuring the accurate monitoring of the flexible sensor. 3. By receiving the excessive stretching force generated during activities such as hunching and bending over, the protrusion is simultaneously driven to extend and directly press against the human skin to generate a tactile reminder. This reminder method, which is synchronized with the user's actions, can directly trigger the body's instinctive reaction, prompting the user to subconsciously adjust poor postures such as bending over and hunching over. Compared with vibration or sound reminders, its corrective reminder effect is more direct and effective. 4. The storage strap and the crank are connected by a detachable sleeve. When a part is accidentally damaged or reaches the end of its service life, only the corresponding part needs to be replaced. 5. The airbag is responsible for fine-tuning during daily activities, ensuring that the flexible sensor always fits snugly. The coil spring handles medium to large movements, providing overall stable adjustment of the adjustment band. The threaded post triggers an alert when poor posture occurs. This allows the underwear to intelligently adapt to various scenarios, from activities of different intensities to poor posture, improving the comfort of wearing it and the reliability of monitoring in different scenarios.

[0023] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0024] See Figures 1-16 As shown, the present invention provides an intelligent human body monitoring underwear, including an underwear body 1, a mounting shell 5 and an adjustment frame 4. An adjustment strap 2 is fixed to the bottom of the underwear body 1, and an adjustment frame 4 is provided between the two ends of the adjustment strap 2 and rotatably disposed inside the mounting shell 5. The mounting shell 5 contains a mounting plate 501. The two ends of the adjusting frame 4 are fixed with curved rods 401 to connect the adjusting belt 2. A coil spring 505 is fixed to the top of the mounting plate 501. The outer end of the coil spring 505 is connected to the adjacent curved rod 401 to wind up the adjusting belt 2. A polygonal post 504 is slidably provided on the top of the mounting shell 5. A fixing groove 504b is opened in the middle of the polygonal post 504 for the inner end of the coil spring 505 to slide up and down in it. The top of the polygonal post 504 is adapted to the top opening of the mounting shell 5. The top of the polygonal post 504 is detachably connected to the mounting shell 5 to adjust the preload of the coil spring 505 and lock the angle of the polygonal post 504 and the coil spring 505, so that the coil spring 505 can maintain the preload after the adjusting belt 2 is stretched to fit the human body.

[0025] When initially wearing the underwear or adjusting its fit, first pull the polygonal post 504 upwards to separate it from the top of the mounting shell 5. At this time, the inner end of the coil spring 505 can rotate freely with the polygonal post 504. Then, according to the required fit, rotate the polygonal post 504. Utilizing its interaction with the inner end of the coil spring 505, the coil spring 505 rotates, simultaneously rotating the adjustment band 2 into the mounting shell 5, thereby adjusting the overall length of the adjustment band 2. During this process, as the adjustment band 2 gradually conforms to the skin, continued rotation of the polygonal post 504 will cause the coil spring 505 to experience resistance from the adjustment band 2 and contract until the adjustment band 2 is completely close to the body. After adjustment, push the polygonal post 504 back into the top of the mounting shell 5, locking the rotation angle of the polygonal post 504. With the preload of the coil spring 505 fixed, the adjusting band 2 can maintain a constant preload when static or during small movements, ensuring that the underwear body 1 fits the body. When the body moves due to breathing, the adjusting band 2 is stretched. This stretching force is transmitted to the outer end of the coil spring 505 through the crank 401, driving the coil spring 505 to overcome its own preload and be pulled. Since the inner end of the coil spring 505 is locked by the polygonal post 504 and the mounting shell 5, its angle cannot be rotated. The stretching of the adjusting band 2 is converted into the deformation of the coil spring 505. When the stretching force disappears, the coil spring 505 releases the elastic force generated by its deformation, generating a coiling force opposite to the stretching force. This force is applied to the adjusting band 2 through the crank 401, causing it to quickly return to its original position and fit the body.

[0026] As an optional implementation, the top of the mounting housing 5 has a polygonal groove 508 (see details). Figure 8 The top of the polygonal column 504 is provided with a polygonal block 504a that matches the polygonal groove 508 to lock the rotation angle of the polygonal column 504. The top of the polygonal block 504a is provided with a locking groove 504c (see details). Figure 9 The buckle groove 504c allows users to easily fasten and adjust the polygonal block 504a after wearing the underwear. A through groove 507 is provided at the bottom of the mounting shell 5. A connecting cylinder 503 is rotatably connected between the mounting plate 501 and the through groove 507. The bottom of the crank rod 401 is fixed to the outer wall of the connecting cylinder 503. An internal thread 503a is provided inside the connecting cylinder 503, and a threaded post 502 is threadedly connected to it. The threaded post 502 is slidably connected to the mounting plate 501. A polygonal opening 502a, adapted to the polygonal post 504, is provided in the middle of the threaded post 502. After the polygonal column 504 descends into the polygonal opening 502a, the rotation angle of the threaded column 502 is locked. When the adjusting belt 2 is stretched, it drives the crank 401 and the connecting cylinder 503 to rotate. The threaded column 502, which is locked in angle, moves up and down through the threaded engagement. A protrusion 502b is fixed at the bottom of the threaded column 502 so that when the adjusting belt 2 is stretched by the human body, it protrudes downward into the through groove 507 to press against the skin. A fixing bracket 506 is fixed on the inner wall of the top of the mounting shell 5, and the bottom of the fixing bracket 506 is attached to the top of the coil spring 505 to suppress the range of movement of the coil spring 505. With this configuration, when poor posture such as hunching or stooping occurs, the adjusting belt 2 will be subjected to a tensile force exceeding the range of daily activities. This tensile force is transmitted to the connecting cylinder 503 through the crank 401, driving the connecting cylinder 503 to rotate around the mounting plate 501. Since the connecting cylinder 503 is threadedly connected to the threaded post 502, and the rotation angle of the threaded post 502 is locked by the polygonal post 504 inserted into its polygonal opening 502a, the rotational motion of the connecting cylinder 503 is transformed into driving the threaded post 502 along the mounting plate 501. As the threaded column 502 moves downward, the protrusion 502b fixed at its bottom protrudes from the through groove 507 at the bottom of the mounting housing 5 and gradually presses against the human skin, producing a noticeable tactile sensation as an immediate reminder, prompting the human body to adjust its posture. When the posture returns to normal, the tension of the adjusting belt 2 decreases, and the winding force of the coil spring 505 drives the adjusting belt 2, the crank 401, and the connecting cylinder 503 to rotate in the opposite direction, thereby driving the threaded column 502 to move upward, so that the protrusion 502b returns to the inside of the through groove 507, and the reminder is released.

[0027] See Figures 2-5 As shown, an airbag 3 is fixed inside the adjusting belt 2. A flexible sensor 6 that conforms to the skin is provided inside the airbag 3. Air supply tubes 301 are fixed on both sides of the airbag 3. A sealing tube 305 is fixedly connected to the end of the air supply tube 301. A sealing rod 302 is slidably arranged inside the sealing tube 305. A sealing block 302a that slides and seals with the sealing tank 305 is fixed to the end of the sealing rod 302. The sealing rod 302 is slidably sealed inside the sealing tube 305. Mounting pads 304 are fixed to the ends of the sealing tube 305 and the sealing rod 302. Two mounting pads 304 are fixed to the outside of the adjusting belt 2. A return spring 303 with its two ends respectively pressing against the sealing block 302a and the end of the sealing tube 305 is sleeved in the middle of the sealing rod 302 (see details). Figure 16The sealing rod 302 is fitted with a return spring 303 at its middle, with its two ends respectively abutting against the ends of the sealing rod 302 and the sealing tube 305. Multiple elastic bands 201 are fixed in the middle of the adjusting band 2. Mounting pads 304 are located on the outer sides of the adjusting bands 2 on both sides of the elastic bands 201. The elastic bands 201 can stretch with human movement, causing the distance between the two adjusting bands 2 to increase or decrease. Each set of mounting pads 304 moves with the adjusting band 2 and pulls the sealing rod 302 and sealing tube 305 to move towards each other to adjust the air pressure inside the airbag 3. This allows the airbag 3 to contract and expand with human movement, keeping the flexible sensor 6 in contact with the human body. With this setup, during activities such as walking and turning, the bending and twisting of the torso will cause the elastic bands 201 in the middle of the adjusting band 2 to repeatedly stretch and rebound, resulting in the distance between the two adjusting bands 2. Dynamic changes occur. When the distance between the adjusting bands 2 on both sides of the elastic band 201 increases, the two sets of mounting pads 304 fixed on the outside of the adjusting band 2 are pulled, causing the sealing rod 302 and the sealing tube 305 to move in opposite directions. The airbag 3 inhales air through the air supply tube 301 and contracts. When the distance decreases, the sealing rod 302 and the sealing tube 305 move closer to each other, pushing the air into the airbag 3 and causing the airbag 3 to expand. During this process, the reset spring 303 provides elasticity to the sealing rod 302, prompting it to respond and reset quickly. By dynamically adjusting the gas in the airbag 3, the flexible sensor 6 inside can continuously contact and adhere to the skin, effectively offsetting the gap between the skin and clothing caused by human activity, thereby ensuring the continuous and accurate signal monitoring of the flexible sensor 6. When the body is active, such as after strenuous exercise when the chest rises and falls significantly, the gap between the adjustment bands 2 widens, the elastic band 201 is stretched, and the adjustment bands 2 on both sides move away from each other. The mounting pads 304 fixed to the outside of the adjustment bands 2 are pulled in opposite directions. One mounting pad 304 drives the sealing tube 305 to move, and the other mounting pad 304 drives the sealing rod 302 to move, so that the sealing rod 302 and the sealing tube 305 slide in opposite directions within their respective sealing tubes 305. During this process, the gas inside the airbag 3 is drawn out through the air delivery tube 301, and the airbag 3 contracts to fit the skin. When the body rises and falls less in daily life, causing the gap between the adjustment bands 2 to narrow, the elastic band 201 rebounds, and at the same time, the return spring 303 pushes the sealing rod 302 back to its original position. The adjustment bands 2 on both sides move closer to each other, and the two sets of mounting pads 304 move towards each other, pushing the sealing rod 302 and the sealing tube 305 closer to each other, forcing air into the airbag 3 through the air delivery tube 301, and the airbag 3 expands. During the process of the sealing rod 302 and the sealing tube 305 moving towards each other, the return spring 303 is compressed; during the process of the two moving away from each other, the return spring 303 restores its deformation and pushes the sealing rod 302 to return to its original position. In actual wear, this intelligent human body monitoring underwear first makes fine adjustments by the airbag 3 to adapt to subtle changes in the torso during daily activities. As the range of motion increases, when the adjustment capacity of the airbag 3 reaches its limit, the tension will be transmitted more to the coil spring 505, which provides a stronger winding and releasing force. When the user's posture is poor, causing the tension to act on the adjustment band 2 and exceed the normal working range of the airbag 3, the tension will drive the protrusion 502b to extend to generate a reminder. In this way, intelligent monitoring can be formed from basic skin fit to body posture intervention based on the intensity of the tension.

[0028] The elastic bands 201 at both ends of the adjusting belt 2 are each fixed with a connecting band 202. A storage band 203, narrower than both the connecting band 202 and the adjusting belt 2, is fixed to the end of each connecting band 202. The end of the storage band 203 is open and fitted onto the middle of the crank 401 to connect the crank 401 and the adjusting belt 2. An outwardly bent intercepting rod 402 is fixed to the outer side of the middle section of the crank 401. The intercepting rod 402 restricts the position of the storage band 203 stored inside the mounting housing 5. The storage band 203 is located on the top U-shaped rod of the crank 401 and can be separated from the crank 401 through the inner side, allowing for replacement and individual maintenance of each component. A fixing rod 401a is fixed to the end face adjacent to the outer end of the crank 401 and the coil spring 505 to connect the coil spring 505 and transmit power. With this configuration, when the adjusting belt 2 is stretched, the storage band 203 rotates with the crank 401. When the tension decreases, the coil spring 505 drives the crank 401 to rotate in the opposite direction to release the adjusting belt 2, and the storage belt 203 is also released. The smaller width of the storage belt 203 allows it to smoothly enter and exit the mounting shell 5. During this process, the intercepting bar 402, which is fixed to the outer side of the middle section of the crank 401, will rotate together with the crank 401. When the storage belt 203 is wound into the mounting shell 5, it will first contact the crank 401. The crank 401 guides the storage belt 203 to the bent end of the intercepting bar 402, thereby preventing the storage belt 203 from continuing to be wound inward, avoiding the storage belt 203 from being over-wound and jammed or interfering with other internal components. The rotation of multiple cranks 401 is synchronized by the adjusting frame 4. The rotation of the cranks 401 is driven by the coil spring 505 to rotate the fixed bar 401a so that the cranks 401, the adjusting frame 4, and multiple cranks 401 rotate synchronously. When wearing this underwear, the adjustment strap 2 goes around the back of the body on both sides and is horizontal in the whole. When the coil spring 505 inside the mounting shell 5 is rolled up or the polygonal column 504 is rotated when wearing it, the outer mounting shell 5 will be limited by the horizontal storage straps 203 on both sides and the storage straps 203 and adjustment strap 2 to keep the position relatively stable, so as to prevent the mounting shell 5 from shifting or rotating significantly as the internal components work.

[0029] Using the above structure, during initial wear, the user first puts on the underwear body 1, so that the adjustment strap 2 located at the bottom wraps around the sides of the body to the back, forming a horizontal shape. Then, the user can adjust the fit of the underwear by pulling upwards on the polygonal post 504 at the top of the mounting shell 5, causing the polygonal block 504a at its top to disengage from the polygonal groove 508 of the mounting shell 5. Next, the user rotates the polygonal post 504 according to the desired fit, causing the coil spring 505 to begin winding up. The crank rod 401 then winds the storage straps 203 at both ends of the adjustment strap 2 into the mounting shell 5, thereby shortening the overall length of the adjustment strap 2. During this process, as the adjustment strap 2 gradually tightens against the skin, the user continues to rotate the polygonal post... 504 will cause the coil spring 505 to experience resistance from the adjusting band 2 and contract until the adjusting band 2 is completely close to the human body. After adjustment, the polygonal post 504 is pushed back into the top of the mounting shell 5, and the polygonal block 504a engages with the polygonal groove 508, locking the preload of the coil spring 505. Because the adjusting band 2 applies a horizontal limiting force to the mounting shell 5 from both sides, even if the internal coil spring 505 is working, the mounting shell 5 can maintain a relatively stable position and will not shift. In daily activities, when the human body breathes or performs small movements such as walking or turning, the dynamic changes of the torso are first sensed by the elastic band 201 in the middle of the adjusting band 2. The stretching and rebound of the elastic band 201 drives the mounting shell 505 on both sides. The padding 304 moves back to back or towards each other, thereby driving the sealing rod 302 and the sealing tube 305 to slide within the sealing tube 305, repeatedly drawing air from the airbag 3, causing the airbag 3 to contract or expand, thus ensuring that the flexible sensor 6 inside is always in close contact with the skin, enabling fine-tuning. When the range of motion increases, such as when bending over or stretching, the elastic band 201 reaches its limit, and the increased tensile force is transmitted to the coil spring 505, driving the coil spring 505 to deform. Subsequently, when the tensile force decreases, the deformation is released, and further adjustment is achieved by rewinding the adjustment band 2, maintaining the underwear's stable fit. Moreover, this tensile force, through the crank rod 401 and the connecting tube 503, drives the threaded column 50, whose angle has been locked. 2. Move downwards so that the bottom protrusion 502b protrudes from the through groove 507 of the mounting shell 5 and presses against the human body, generating a tactile reminder. When the user adjusts their posture, the pulling force decreases, the coil spring 505 resets, and the protrusion 502b resets, thus deactivating the reminder. During the entire process of winding and unwinding the adjustment belt 2, the storage belt 203 rotates synchronously with the crank 401. Its small width ensures smooth entry and exit from the mounting shell 5. The intercepting bar 402 in the middle of the crank 401 will intercept the storage belt 203 after it is wound into place, preventing over-winding and jamming. When maintenance or replacement is required, simply separate the storage belt 203 from the U-shaped bar at the top of the crank 401, enabling individual maintenance of each component.

[0030] When wearing, the preload of the coil spring 505 can be adjusted by rotating the polygonal post 504 to match different personal preferences for tightness. During the wearing process, when the human body fluctuates due to normal activities such as breathing, the coil spring 505 can absorb and compensate for these subtle size changes in real time through its own deformation and rebound, so that the adjustment band 2 always maintains a constant preload, which not only ensures personalized initial comfort, but also achieves continuous tightness during the activity. The airbag 3 is connected to the sealing tube 305 through the air supply tube 301 and dynamically inhales or inflates during daily activities. It is always filled between the sensor and the skin, pressing the flexible sensor 6 to maintain continuous and stable contact with the skin, reducing problems such as signal loss due to poor contact, and ensuring the accurate monitoring of the flexible sensor 6. By receiving the excessive stretching force generated during activities such as hunching and bending over, the protrusion 502b is simultaneously driven to extend and directly press against the human skin, generating a tactile reminder. This reminder method, which is synchronized with the user's actions, can directly trigger the body's instinctive reaction, prompting the user to subconsciously adjust poor postures such as bending over and hunching over. Compared with vibration or sound reminders, its corrective reminder effect is more direct and effective. The storage strap 203 and the crank 401 are connected by a detachable sleeve. When a component is accidentally damaged or reaches the end of its service life, only the corresponding component needs to be replaced. Airbag 3 is responsible for fine-tuning during daily activities, ensuring that flexible sensor 6 always fits snugly. Coil spring 505 handles medium to large movements, providing stable adjustment of the overall adjustment band 2. Threaded post 502 triggers a reminder when poor posture occurs. This allows the underwear to intelligently adapt to various scenarios, from activities of different intensities to poor posture, improving the comfort of wearing and the reliability of monitoring in different scenarios.
