Description

Technical Field

[0001] This invention relates to the field of ergonomic support device technology, and in particular to a human waist and abdomen binding device with an automatically inflatable and deflated airbag. Background Technology

[0002] In applications such as rehabilitation medicine, exoskeleton support, sports assistance, and industrial protection, the stability and support of the human waist and abdomen are key factors for achieving effective weight-bearing and movement assistance. Traditional waist and abdomen binding devices mostly use elastic materials or mechanical structures for fixation and support. Although they can provide restraint and restriction to a certain extent, they generally suffer from poor fit, insufficient comfort, limited adjustment methods, cumbersome wearing, and poor adaptability to different waist sizes.

[0003] In recent years, with the development of flexible materials and intelligent control technology, airbag support structures have been gradually introduced into human restraint devices. This structure forms a controllable support surface through airbag inflation, which not only improves wearing comfort but also allows for adaptive adjustment of support strength based on individual user differences and specific application scenarios. However, existing airbag systems still have many shortcomings:

[0004] 1. Most systems rely on manual inflation or a single air pressure regulation mechanism, making it difficult to achieve dynamic feedback control and precise adjustment;

[0005] 2. It lacks an efficient automatic inflation and deflation control system, making it unable to respond in real time to the human body's condition during use.

[0006] 3. The airbag restraint device of the airbag system still mainly uses traditional buckles, zippers or elastic bands for fixing. It lacks a highly modular, adjustable and structurally stable fixing mechanism, which makes the device prone to displacement and loosening in dynamic movement or long-term wear scenarios, affecting the use effect and user experience. Summary of the Invention

[0007] The purpose of this invention is to provide a human waist and abdomen binding device with an automatically inflatable and deflated airbag, to solve the problems of inconvenient inflation control, unstable fixing structure, and poor adaptive performance due to the lack of intelligent feedback adjustment capability in the prior art. To achieve the above objective, this invention adopts the following technical solution:

[0008] An adaptive human waist and abdomen binding device includes a support frame, a fixing structure, an airbag assembly, and an automatic inflation and deflation device.

[0009] The support frame includes a support structure; the support structure is a contoured frame structure made entirely of high-strength and tough material, designed to conform to and encircle the waist and abdomen of the human body, with its inner wall serving as a contact layer that conforms to the human body; the high-strength and tough material refers to a material with a tensile strength of not less than 500 MPa and an impact toughness of not less than 80 KJ / m. 2 The materials used include titanium alloy, stainless steel, carbon fiber reinforced composite materials, aramid fiber, or thermoplastic polyurethane. By selecting these materials, the support frame has sufficient strength to withstand the load on the waist and abdomen while maintaining the necessary flexibility, effectively improving wearing comfort.

[0010] The fixing structure is located on the outside of the support structure and is fixedly connected to the support structure. It is used to tighten and fix the support frame to the waist of the human body.

[0011] The airbag assembly is located on the side of the contact layer away from the fixed structure and fits in close contact with the human body, and is used to apply pressure to the waist and abdomen of the human body when inflated.

[0012] The automatic inflation / deflation device is connected to the airbag assembly via an air passage and is used to control the inflation and deflation of the airbag assembly.

[0013] Furthermore, the support frame also includes anchor points for connecting external auxiliary devices. The anchor points are evenly distributed along the axial direction on the upper and lower peripheries of the support structure, and the anchor points on the upper periphery are aligned with the anchor points on the lower periphery in the vertical direction.

[0014] Furthermore, the support structure is a modular structure, including at least two detachably connected frame modules; the frame modules include a lumbar module for supporting the waist and an abdominal module for supporting the abdomen.

[0015] Furthermore, the detachable connection method is one of snap-fit ​​connection, magnetic connection or screw connection.

[0016] Furthermore, the contact layer is provided with hook and loop slots for adapting hook and loop fasteners, and friction layers; the friction layers are spaced between the hook and loop slots to increase the frictional fit between the contact layer and the airbag assembly.

[0017] Furthermore, the fixing structure includes an adjustable fixing strap, a plug assembly, a lock seat assembly, a locking mechanism, and a locking button; the adjustable fixing strap is fixed to the support structure by anchor points; the plug assembly is fixed to one end of the adjustable fixing strap and has multiple levels of insertion teeth; the locking device is configured to be detachably fixed relative to the support structure and has multiple locking teeth; the locking mechanism is disposed within the locking assembly and is configured to engage with the multiple locking teeth when the plug assembly is inserted into the slot to prevent the plug assembly from exiting, thereby achieving one-way locking; the locking button is operably connected to the locking mechanism and is used to release the locking mechanism from the locking teeth to release the plug assembly.

[0018] Furthermore, the airbag assembly includes an airbag body and an airtight structure disposed on the airbag body; the side of the airbag body near the contact layer is provided with an adhesive layer that adheres to the Velcro; the airtight structure includes an airtight air tube and a one-way valve; one end of the airtight air tube is connected to the airbag, and the other end is connected to an automatic inflation / deflation device for introducing and expelling gas; the one-way valve is disposed in the air passage of the air tube to prevent gas backflow and ensure the stability of the air pressure inside the airbag and the safety of use.

[0019] Furthermore, the automatic inflation / deflation device includes a power management module, a first sensing module, a second sensing module, an intelligent control module, a first execution module, and a second execution module;

[0020] The power management module is used to provide power to each component;

[0021] The first sensing module is located on the airbag assembly and is used to detect the air pressure changes inside the airbag cavity in real time; the second sensing module is located between the contact layer and the airbag assembly and is used to detect the contact pressure between the binding device and the human waist and abdomen.

[0022] The intelligent control module receives air pressure changes provided by the first sensing module and contact pressure provided by the second sensing module. Based on the received air pressure changes and contact pressure, it determines the current state of the airbag assembly. Based on the determined current state and a set range, it generates an inflation command and sends it to the first execution module, and generates a deflation command and sends it to the second execution module; it also collects the current operating status of the device.

[0023] The first execution module inflates and pressurizes the airbag according to the inflation command, while the second execution module automatically deflates the airbag according to the deflation command, so as to adjust the pressure inside the airbag and ensure the dynamic balance and adaptive adjustment of the support force.

[0024] Furthermore, the automatic inflation / deflation device also includes a user interaction module, which includes physical buttons and indicator light components. The physical buttons can send manual inflation commands as needed, which are transmitted to the first execution module via the intelligent control module to perform inflation operations, and send manual deflation commands, which are transmitted to the second execution module via the intelligent control module to perform deflation operations. Based on the operating status collected by the intelligent control module, the device provides feedback on the current operating status.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. The support structure of the present invention adopts a contoured frame structure that surrounds the waist and abdomen of the human body, combined with an airbag structure design that is adapted to its shape, so that it can fit the curve of the waist and abdomen of the human body, effectively disperse pressure, and improve the comfort during long-term wear.

[0027] 2. This invention introduces an automatic inflation and deflation device. Through the coordinated work of sensors and intelligent control modules, the support strength of the airbag components can be automatically adjusted to meet the personalized needs of different user body types or dynamic usage scenarios.

[0028] 3. The fixing structure of the present invention consists of a multi-level buckle and locking mechanism, which can ensure the stability and reliability of the device when worn, and also has good ease of putting on and taking off.

[0029] 4. The support structure of this invention is a modular structure, which makes the components easy to assemble and disassemble, which is conducive to later maintenance and functional expansion, and can be flexibly adapted to various exoskeletons or auxiliary systems. In addition, this device is suitable for multiple application scenarios such as medical rehabilitation, industrial protection, and wearable robots, and has good practicality and broad market prospects.

[0030] In summary, this invention effectively solves the technical problems of uneven support, inconvenience of wearing, and lack of intelligent adjustment in traditional binding structures, achieving dynamic support and comfortable wearing for the waist and abdomen area, and has good practicality and promotional value.

Detailed Implementation

[0038] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0039] like Figure 1 The adaptive waist and abdomen binding device 110 provided in this embodiment includes a support frame 111, a fixing structure 112, an airbag assembly 113, and an automatic inflation / deflation device 114; the various structural parts work together to provide stable, comfortable, and adjustable support for the waist and abdomen.

[0040] The support frame 111 serves as the main load-bearing structure of the entire binding device 110, providing basic support for the human waist and abdomen.

[0041] The fixing structure 112 is used to securely fit the binding device 110 to the user's waist and abdomen, and features flexible adjustment, reliable locking, and convenient wearing. Its core, through a multi-level adjustment and one-way locking mechanism, adapts to the size needs of users with different waist sizes and ensures secure fixation during use.

[0042] The airtight structure 1132 of the airbag assembly 113 is responsible for controlling the unidirectional transmission and sealing of gas, ensuring that the airbag maintains a stable air pressure during inflation and deflation, thereby providing a continuous and safe support effect.

[0043] The automatic inflation / deflation device 114 integrates multiple modules that work together to automatically adjust the inflation and deflation of the airbag. This device can sense real-time changes in airbag pressure and pressure intensity in the area of ​​contact with the human body, and processes and makes decisions based on the intelligent control module to regulate the inflation and deflation of the airbag, ensuring the comfort and stability of the restraint device.

[0044] like Figure 2 As shown, the support frame 1111 in this embodiment includes a support structure 1111. The support structure 1111 is a contoured frame structure made entirely of high-strength and tough material, designed to conform to and surround the waist and abdomen of the human body. Its inner wall is a contact layer that conforms to the human body, providing basic support for the waist and abdomen, i.e., maintaining the shape stability of the binding device 110 during wear. To further enhance the synergy between the support structure 1111 and the airbag assembly 113, a Velcro slot 1114 and a friction layer 1115 are provided on the contact layer. The Velcro slot 1114 is used to cooperate with the Velcro adhesive layer of the airbag assembly 113, thereby achieving a stable connection between the two for quick assembly and disassembly and accurate positioning. The friction layer 1115 is spaced between the Velcro slots 1114 to increase the friction between the contact layer and the airbag assembly 113, effectively preventing the airbag assembly 113 from sliding or shifting during use, and improving wearing comfort and overall stability. The outer peripheral wall of the support structure 1111 is also provided with a fixing buckle 1113, which is used to engage with the fixing structure 112 to achieve preliminary positioning and assembly.

[0045] In other embodiments, the support structure 1111 adopts a modular design, allowing for the replacement of support components of different specifications according to different body shapes or usage requirements, thereby improving the device's adaptability and maintainability. Specifically, the support structure 1111 includes at least two detachably connected frame modules; the frame modules include a lumbar support module for supporting the waist and an abdominal support module for supporting the abdomen. The detachable connection between the frame modules can be achieved through a snap-fit ​​connection, sliding groove positioning, magnetic connection, or screw connection, enabling quick assembly and disassembly for easy cleaning and replacement.

[0046] In other embodiments, the support frame further includes anchor points 1112 for connecting external auxiliary devices. Anchor points 1112 are evenly spaced along the axial direction on the upper and lower peripheries of the support structure 1111, with the anchor points 1112 on the upper periphery and lower periphery aligned vertically. The anchor points 1112 feature a rotatable design, supporting flexible multi-angle adjustment, making them perfectly suited for applications requiring multi-dimensional fixation, such as sports rehabilitation and posture guidance. Some anchor points 1112 also integrate magnetic components, enabling rapid adsorption and replacement of magnetic attachments, significantly improving ease of use and functionality.

[0047] In other embodiments, the fastener 1113 adopts a quick-release design. By integrating buttons, sliders, and other structures on the fastener 1113, users can complete the locking or unlocking process with one hand, improving the ease of wearing. The fastener body is made of high-strength engineering plastics or carbon fiber reinforced materials, possessing good wear resistance and fatigue resistance.

[0048] like Figure 3 As shown, in this embodiment, the fixing structure 112 includes an adjustable fixing strap 1121 and a multi-level buckle 1122 structure disposed on the adjustable fixing strap. The adjustable fixing strap 1121 is fixed to the support structure 1111 by anchor points; it is made of a flexible polymer material with good tensile strength and resilience, such as TPU or nylon composite material, which can adapt to the waist and abdomen circumference of different users during wearing. The adjustable fixing strap 1121 is provided with multiple through holes or positioning grooves for users to adjust the length by adjusting the insertion depth; thereby ensuring the fit and comfort of the binding device on users of different body types. The multi-level buckle 1122 consists of a plug assembly 1124, a locking device 1123, a locking mechanism, and a locking button 1125. The plug assembly 1124 is fixed to one end of the adjustable fixing strap 1121 and has multiple teeth, forming the core component of the multi-level buckle 1122. The locking device is configured to be detachably fixed relative to the support structure 1111 and has multiple teeth for engaging with the teeth to achieve locking. The locking mechanism is located within the locking device 1123 and is configured to engage with the teeth when the plug assembly 1124 is inserted into the slot to prevent the plug assembly 1124 from exiting, achieving one-way locking. The locking button 1125 is operably connected to the locking mechanism and is used to release the engagement between the locking mechanism and the teeth to release the plug assembly, thereby loosening or removing the fixing strap. Through the above structural design, the fixing structure 112 not only has good adjustability and wearing stability but also can be reused multiple times without being easily damaged. While improving ease of use, it effectively enhances the safety and durability of the binding device, and is easy to operate and reliable.

[0049] In other embodiments, the outer surface of the adjustable fixing strap 1121 is provided with guide marking lines and scales, which makes it easy for users to accurately control the insertion length during wearing, and is suitable for rehabilitation training or medical fixation scenarios with high positioning requirements.

[0050] In other embodiments, to accommodate users with varying waist and abdominal circumferences, such as children or the elderly, the adjustable fixing strap 1121 adopts a bidirectional extendable structure. The plug assembly 1124 fixed at the end has symmetrically arranged guide tabs on both sides, forming a double-sided engagement with the locking devices 1123 arranged on both sides. Through the gap fit between the guide tabs and the locking devices 1123, and the locking fit between the guide tabs and the locking devices 1123, the binding tension of the fixing strap 1121 is symmetrically distributed on both sides, improving the device's tensile strength and binding stability, ensuring a good fit and reliable use for users of different body types.

[0051] In other embodiments, the multi-level buckle 1122 adopts a magnetic assisted structure. When the plug assembly 1124 approaches the locking device 1123, the built-in magnet can automatically assist in insertion and complete the initial positioning, improving wearing efficiency. It is especially suitable for users who operate with one hand or have limited mobility.

[0052] In other embodiments, the locking button 1125 is designed to prevent accidental contact, and is provided with an external sliding cover or a pressing threshold limiting mechanism to avoid accidental contact during wear and further enhance the overall wearing safety of the device.

[0053] In other embodiments, the locking device 1123 integrates a dual mechanism of mechanical lock and electronic release, allowing users to remotely unlock the device via Bluetooth / remote control commands in emergency situations or special scenarios. This is suitable for special applications requiring remote monitoring, such as rehabilitation training monitoring and elderly care.

[0054] like Figure 4 As shown, the airbag assembly 113 of this embodiment includes an airbag body 1131 and an airtight structure 1132 disposed on the airbag body 1131; the side of the airbag body 1131 near the contact layer is provided with an adhesive layer that adheres to the Velcro. The airbag body 1131 is integrally molded from a flexible polymer material, and its overall structure is adapted to the support structure 1111, which can conform to the curve of the human waist and abdomen and provide uniform support. The airtight structure 1132 is used to ensure the unidirectional and airtightness of gas transmission and maintain the stable air pressure inside the airbag 1131. The airtight structure 1132 includes an airtight air tube and a one-way valve; one end of the airtight air tube is connected to the airbag, and the other end is connected to an automatic inflation and deflation device for realizing the introduction and discharge of gas; the one-way valve is disposed in the air passage of the air tube to prevent gas backflow.

[0055] In other embodiments, the airtight structure 1132 includes a first airtight air tube 1133, a second airtight air tube 1134, a first one-way valve 1135, and a second one-way valve 1136. One end of the first airtight air tube 1133 is connected to the first execution module 1145 of the automatic inflation / deflation device 114, and the other end is connected to the first one-way valve 1135 (i.e., the airbag inlet), for realizing one-way inflation. One end of the second airtight air tube 1134 is connected to the second execution module 1146, and the other end is connected to the second one-way valve 1136 (i.e., the airbag exhaust port), for realizing one-way exhaust, preventing gas backflow or leakage, thereby maintaining stable air pressure inside the airbag 1131. A Velcro structure that mates with the support structure 1111 is provided on the side of the airbag assembly 113 near the contact layer. This embodiment also provides a friction layer 1115 on the inner surface of the airbag assembly, which provides additional friction during contact with the human body, preventing the airbag assembly 113 from sliding or shifting during use, and further improving the stability and comfort of wearing it. Through the coordinated operation of the above structures, the airbag assembly 113 can always maintain the predetermined position during actual wear, ensuring the consistency and reliability of the support effect and user experience.

[0056] In other embodiments, the integrated airbag 1131 has multiple partitioned air chambers inside, which are formed into independent zones by heat sealing or laser welding. This can effectively prevent uneven local expansion caused by gas concentration during inflation, and achieve a more balanced support distribution, which is suitable for fine support needs such as postoperative rehabilitation or posture correction.

[0057] In other embodiments, the outer layer of the airbag assembly 113 adopts a composite three-layer structure, consisting of, from the outside in: a skin-friendly surface layer, a reinforcing layer, and an airtight layer. The skin-friendly surface layer is in direct contact with the human body, ensuring wearing comfort. The reinforcing layer improves the overall tensile and tear resistance of the outer layer, ensuring structural stability after inflation. The airtight layer is used to achieve sealing and pressure retention after inflation, preventing gas leakage. The three layers work together to ensure both comfort and good pressure and tear resistance, meeting the reliability requirements of long-term repeated inflation and deflation scenarios.

[0058] In other embodiments, a miniature pressure sensor is integrated within the airtight structure 1132 as a second transmission module to monitor changes in air pressure inside the airbag in real time, and to feed the data back to the user interaction module 1147 via a communication module, thereby enabling visualization and automatic control of the air pressure status and further enhancing the intelligence level of the device.

[0059] In other embodiments, to further optimize the user's wearing experience, the airbag assembly 113 is provided with a built-in dehumidifying layer, which can release heat and moisture appropriately during wearing to prevent discomfort such as stuffiness and sweating caused by prolonged contact with the human body.

[0060] In other embodiments, the first airtight air tube 1133 and the second airtight air tube 1134 both adopt a quick-plug interface design, which can be flexibly adapted to the first interface 1137 and the second interface 1138 respectively to form a snap-fit ​​connection; the snap-fit ​​structure of the interface not only ensures the convenience of plugging and unplugging, but also ensures the sealing and stability after connection, which is suitable for high-frequency use environments such as public places and hospitals.

[0061] In other embodiments, to achieve modular configuration, the airbag assembly 113 is provided with multiple sets of parallel air intake and exhaust channels. Users can select single airbag mode or multi-airbag linkage mode according to actual needs, which is suitable for various functional scenarios such as lumbar support, abdominal compression, and core training.

[0062] like Figure 5 As shown, the automatic inflation / deflation device 114 of this embodiment includes a power management module 1141, a first sensing module 1142, a second sensing module 1143, an intelligent control module 1144, a first execution module 1145, a second execution module 1146, and a user interaction module 1147. The system includes a power management module 1141 that provides stable power support for the entire system and has functions such as battery management, power monitoring, and power consumption optimization; a first sensing module 1142 that monitors the air pressure changes inside the airbag 1131 in real time and assesses the airbag pressure level; a second sensing module 1143 that detects the pressure intensity of the area where the airbag assembly 113 contacts the human body and assesses the current support status; an intelligent control module 1144 that acts as a central processing unit, comprehensively judges the sensing signals based on a preset logic program, and makes adjustment decisions; a first execution module 1145 that is the inflation device for the airbag assembly 113 and executes inflation and pressurization actions in response to control signals; a second execution module 1146 that is the deflation device for the airbag assembly 113 and executes deflation and decompression actions in response to control signals; and a user interaction module 1147 that provides the user with device status display and operation buttons, supporting button control or remote management. Through the organic cooperation of the above modules, the automatic inflation / deflation device 114 can automatically adjust the inflation state of the airbag according to real-time detection data, so as to realize intelligent control and personalized adaptation of the restraint device 100 in different usage scenarios.

[0063] In this embodiment, the power management module 1141, as the core energy supply unit of the automatic charging and discharging device 114, integrates a high-energy-density rechargeable battery unit to provide continuous and stable DC power output to the other sub-modules. To ensure the safety of the power supply process and the stability of the system, this module is equipped with multiple protection and control circuits: it has a power switch control function, which can realize the power supply of the whole machine on and off during user operation or system self-test, preventing unnecessary power consumption in non-working state; it has an overvoltage protection function, which automatically cuts off the output when the voltage exceeds the set threshold to avoid high voltage damage to circuit components; it has a low battery reminder mechanism, which issues a visual or audible reminder through the user interaction module 1147 when the battery power is lower than the safe lower limit, prompting the user to charge in time; it also includes a power consumption intelligent management unit, which can dynamically adjust the power supply strategy of each sub-module according to the system working status, such as reducing the power supply in standby or non-interactive state, effectively extending the device's battery life. Through the above design, the power management module 1141 not only ensures the continuity and safety of the binding device 100 in complex application environments, but also improves the overall intelligent management level and user experience.

[0064] In some embodiments, the power management module 1141 integrates a high-energy-density lithium battery and, in conjunction with an intelligent power management unit, can dynamically adjust the battery power supply strategy according to different operating modes. For example, when the device is in standby mode, the system automatically enters a low-power state, shutting down unnecessary modules (such as the first execution module 1145 and the second execution module 1146), maintaining only the basic operation of the intelligent control module 1144 and the sensing module, thereby maximizing battery life. When the user starts the device for actual operation, the power management module automatically switches to a high-power mode, providing stable power output.

[0065] In other embodiments, the power management module 1141 has an automatic low-battery protection function. When the battery level is lower than a set threshold (e.g., 20%), the system automatically activates a power-saving mode, limiting the operation of some high-power modules (such as disabling inflation and deflation functions), and issues a low-battery reminder through the user interaction module 1147, prompting the user to charge the battery in time. Furthermore, the user interaction module 1147 displays real-time battery level data and provides visual feedback on the charging progress when a charger is connected, ensuring that the user can monitor the device's battery status at any time.

[0066] In some embodiments, the power management module 1141 integrates a temperature sensor and overvoltage protection circuit. When the system detects that the battery temperature exceeds a safe threshold, the power management module automatically reduces the battery charging speed to prevent overheating; if the battery voltage exceeds a set safe value, the module automatically cuts off the power output to prevent battery damage or circuit overload. In this way, the system can automatically protect itself under high temperature or abnormal voltage conditions, improving the safety and durability of the device.

[0067] In other embodiments, the power management module 1141 has an intelligent charging function. When the device is connected to a power source via the charging interface, the system can intelligently adjust the charging strategy based on the remaining battery power and the power supply status. For example, when the battery power is low, the power management module will use a fast charging mode, and automatically switch to a trickle charging mode when it reaches 80%, extending battery life and reducing heat generation during charging. Furthermore, when the device shuts down due to depleted power, the user can quickly restore system functionality by connecting a charger, and continue using it after charging.

[0068] In some embodiments, the power management module 1141 supports multiple power input interfaces (such as USB-C, DC interface, etc.) and can automatically adjust the current input strategy according to the type of charging device. For example, when connected to a standard USB interface, the system automatically switches to a low-current charging mode; while when connected to a high-current adapter, the system enters a fast charging mode. Furthermore, the power management module also supports wireless charging, providing users with a more flexible and convenient charging solution and enhancing the user experience.

[0069] In some embodiments, the power management module 1141 integrates battery health detection and optimization functions. The intelligent control module 1144 periodically performs self-tests on the battery to assess its capacity and health status. If battery aging or damage is detected, the system will issue an advance warning to the user, reminding them to replace the battery. This function helps users replace the battery in a timely manner, avoiding disruption to normal device use due to battery performance degradation.

[0070] The binding device 100 provided in this application embodiment connects and fixes the first sensing module 1142 and the second sensing module 1143 by setting a first interface 1137 and a second interface 1138 on the airbag assembly 113, thereby ensuring the stability of the data collected by the sensing modules. Figure 1 In the illustrated embodiment, the first interface 1137 is disposed on the inner surface of the integrated airbag 1131. Figure 1The illustrated embodiment uses a multi-channel pressure sensor composed of multiple single-channel pressure sensors to collect the contact pressure between the human body and the airbag 1131. This embodiment also provides the airbag assembly 113 with one-way inflation and deflation functions by setting a first one-way valve 1135 and a second one-way valve 1136 on the airbag assembly 113. The first one-way valve 1135 is connected to the first execution module 1145 of the automatic inflation / deflation device 114 via a first airtight air pipe 1133. Simultaneously, the second one-way valve 1136 is also connected to the second execution module 1146 via a second airtight air pipe 1134, ensuring the airtightness of the entire airbag assembly 113 and preventing air leakage during inflation and deflation that could lead to unstable airbag pressure. This embodiment also uses a first sensing module 1142 to monitor the internal air pressure of the airbag 1131 in real time and transmits the sensing data to the intelligent control module 1144 as a first signal. Meanwhile, this embodiment of the application also dynamically monitors the spatial contact pressure between the airbag assembly 113 and the human body by setting a second sensing module 1143, and transmits the sensing data to the intelligent control module 1144 as a second signal.

[0071] In other embodiments, the first sensing module 1142 employs a thin-film pressure sensor with an ultra-thin and flexible structure that can be directly laid on the inner surface of the airbag 1131. The thin-film pressure sensor enables highly sensitive monitoring of contact pressure and provides real-time data acquisition without increasing the airbag volume. This sensor is particularly suitable for dynamically monitoring pressure changes between the airbag and the human body, allowing the system to dynamically adjust the airbag's inflation state based on real-time feedback, thereby ensuring a comfortable pressure range is maintained throughout the wearing process.

[0072] In some embodiments, the first sensing module 1142 employs a multi-point distributed sensor network, uniformly distributing multiple pressure sensors across different areas of the inner surface of the airbag 1131 to accurately capture the pressure distribution between the human body and the airbag. In this embodiment, the sensor network transmits data to the intelligent control module 1144 via wireless communication technology. The sensors can report pressure data in real time and dynamically adjust the airbag's pressure value according to the system's algorithm to ensure comfort at each contact point.

[0073] In other embodiments, the second sensing module 1143 is used to monitor the contact pressure between the airbag assembly 113 and the human body. By integrating miniature pressure sensors on the skin in the contact area, the second sensing module can sense pressure changes in different activity states of the user. For example, the pressure distribution of the human body may change when standing or walking, and the second sensing module can dynamically collect and transmit this data to the intelligent control module 1144 in real time. Based on this data, the system will adjust the inflation or deflation of the airbag in a timely manner to maintain a comfortable wearing experience and prevent discomfort or device damage due to excessive pressure.

[0074] In some embodiments, the second sensing module 1143 integrates a temperature sensor in addition to a pressure sensor. This composite sensing module can monitor temperature changes in the area where the airbag assembly 113 contacts the human body, ensuring that the airbag does not experience pressure instability or discomfort due to temperature fluctuations in different environments. The sensing data is simultaneously transmitted to the intelligent control module 1144, which can comprehensively consider temperature and pressure factors and make appropriate adjustments to ensure that the airbag still provides comfortable support even in environments with large temperature variations.

[0075] The intelligent control module 1144 in this embodiment automatically adjusts the inflation state of the airbag according to a preset logic program based on the first and second signals, thereby ensuring that the user's waist and abdomen area receives ideal support and comfort. The intelligent control module 1144 includes a state layer and an execution layer. The state layer is used to determine whether the support state meets the standard, and the execution layer is used to execute corresponding adjustment actions. Specifically, the state layer includes a first detection module and a second detection module. The first detection module is responsible for receiving and processing the first signal from the first sensing module 1142, i.e., the air pressure data inside the airbag; the second detection module is responsible for receiving and processing the second signal from the second sensing module 1143, i.e., the pressure data of the area where the airbag contacts the human body. Both detection modules comprehensively evaluate the current support state through built-in data processing algorithms to determine whether it is within the set comfort range. After completing data analysis and support state evaluation at the state layer, an inflation or deflation control command signal is sent to the execution layer. To ensure the clarity of the system's execution logic and the stability of the inflation / deflation operation, the state layer employs a mutual exclusion mechanism when issuing control commands: at any given time, only one control command signal—either inflation or deflation—is allowed to be generated and sent, preventing simultaneous triggering of both operations and potential control conflicts or airbag malfunctions. The execution layer includes a first control module and a second control module, respectively used to control the inflation and deflation of the airbag assembly 113. After receiving the control command signal from the state layer, the execution layer, depending on its type, sends an inflation command from the first control module to the first execution module 1145 (electric air pump), or a deflation command from the second control module to the second execution module 1146 (electromagnetic deflation valve), thus automatically adjusting the airbag pressure to ensure the wearer remains in a comfortable and stable support state. Simultaneously, the execution layer of the intelligent control module 1144 also transmits a third signal (feedback signal) to the user interaction module 1147, providing a basis for user operations. Through the user interaction module 1147, the user can view the device status and adjust the support intensity in real time. In other embodiments, users can remotely control the device's on / off state and inflation level, ensuring that the device can meet personalized needs in different usage scenarios.

[0076] In some embodiments, the intelligent control module 1144 supports wireless communication with external devices to achieve remote control functionality. Through the user interaction module 1147, users can view the current status of the restraint device (such as airbag pressure, contact pressure, etc.) in real time and adjust the airbag inflation and support strength as needed. Users can also remotely control the device using a dedicated application on a smartphone or tablet. Through wireless connections such as Wi-Fi or Bluetooth, users can adjust the device's status to adapt to different wearing needs or scenarios, such as personalized adjustments to support strength during daily use, exercise, or rest.

[0077] In some embodiments, the intelligent control module 1144 supports multiple operating modes, allowing users to select different modes according to their needs. For example, a user can choose a "comfort mode" to provide lower support, suitable for extended wear; a "sports mode" to provide higher support, suitable for exercise and activities; and a "rest mode" to make the airbag inflation lighter, suitable for use during rest. In each mode, the intelligent control module automatically adjusts the airbag's state based on real-time detected air pressure and pressure data to provide the most suitable comfort experience.

[0078] In some embodiments, the intelligent control module 1144 is integrated with health monitoring functions to provide personalized health assessments. For example, the system not only monitors airbag pressure in real time but also analyzes the user's health status by combining with other sensing devices (such as heart rate monitors and body temperature sensors). When the system detects that the user is fatigued or under excessive pressure, the intelligent control module can automatically adjust the airbag inflation state based on health data to reduce pressure or increase support, helping the user regain comfort. This function is particularly suitable for users who wear the device for extended periods, enabling intelligent health management.

[0079] In some embodiments, the intelligent control module 1144 supports receiving user posture information and acquiring the user's motion state and positional changes in real time through integrated posture sensors (such as accelerometers, gyroscopes, etc.). These sensors can detect changes in the user's posture, such as transitions from a sitting to a standing posture, leaning forward, or leaning back. Based on this data, the intelligent control module 1144 can dynamically adjust the inflation state of the airbag to ensure that the user receives appropriate support in different postures.

[0080] In this embodiment, the first execution module 1145 is an electric air pump, and the second execution module 1146 is an electromagnetic exhaust valve. Both correspond to the inflation and deflation control tasks of the airbag assembly 113, respectively, and both achieve gas flow control through a one-way valve within the airbag assembly 113. When the intelligent control module 1144 determines that the airbag needs to be inflated based on its state layer command signal, it sends an inflation command to the first execution module 1145. Upon receiving the command, the electric air pump 1145 immediately starts, driving the compression unit via its internal drive motor to introduce air from the external environment and push it into the interior of the integrated airbag 1131 through a connected airtight air tube. This process relies on the one-way conduction characteristic of the first one-way valve 1134 connected to the electric air pump 1145, ensuring that air can only enter the airbag from the pump end and cannot leak backwards, thus achieving a safe and stable inflation process. When the intelligent control module 1144 determines that the internal pressure of the airbag needs to be reduced, the second control module sends an exhaust command signal to the second execution module 1146. Upon receiving the command, the electromagnetic exhaust valve 1146 is energized and opens, its internal electromagnetic structure responding rapidly to open the exhaust channel. At this time, the high-pressure gas inside the airbag is discharged along the second airtight air tube through the second one-way valve 1135, and quickly released to the external environment, completing the exhaust process. Because the exhaust path also has a one-way design, the discharged gas will not flow back, ensuring that the deflation process is controlled, rapid, and effective.

[0081] In some embodiments, the first execution module 1145 and the second execution module 1146 can work in conjunction to form a dual-path inflation and deflation system. For example, in some special scenarios (such as prolonged wear or during exercise), the intelligent control module 1144 will control the inflation and deflation modules in conjunction with each other based on the user's activity status or real-time air pressure changes. For example, the electric inflation pump and the electromagnetic deflation valve operate simultaneously, maintaining a constant pressure in a specific area of ​​the airbag. The intelligent control module 1144 adjusts the working state of each execution module based on real-time data to ensure that the airbag support and comfort are always at their best.

[0082] In some embodiments, the second execution module 1146 is not only used for venting air, but also for automatic venting and pressure recovery. When the airbag is under high pressure for an extended period, the electromagnetic vent valve 1146 automatically and periodically opens to vent air, maintaining the pressure inside the airbag within a suitable range. This mode is particularly suitable for long-term use scenarios, such as during sleep or prolonged sitting, where the airbag can automatically vent air to prevent excessive compression, thereby avoiding discomfort or adverse consequences. Simultaneously, during the venting process, the electromagnetic vent valve can dynamically adjust the venting volume based on feedback data from the pressure sensor, preventing airbag instability caused by rapid pressure changes.

[0083] In other embodiments, the first execution module 1145 and the second execution module 1146 support multi-level adjustment. The inflation and deflation of the airbag are not merely controlled by a switch, but rather through multiple operating levels for fine-tuning. For example, the electric air pump in the first execution module 1145 can provide multiple inflation levels, offering different inflation pressures for different usage scenarios (such as sitting, standing, lying down, etc.). Similarly, the electromagnetic deflation valve in the second execution module 1146 supports multi-level deflation adjustment, gradually releasing gas as needed to maintain balanced airbag pressure throughout use.

[0084] In other embodiments, the control logic for the electric air pump and the electromagnetic exhaust valve is dynamically combined based on the user's real-time needs and the system status. Through the control logic of the intelligent control module 1144, the two execution modules can automatically adjust according to the external environment or the user's activities. For example, when the user begins to exercise, the electric air pump automatically operates to increase the support force; when the exercise ends, the electromagnetic exhaust valve begins to release gas to restore the pressure balance of the airbag. The system dynamically determines the need for inflation or deflation based on data from the sensor module, achieving automatic adjustment to ensure the comfort and safety of the airbag in different usage scenarios.
