Description

Technical Field

[0001] This utility model is a jacket with an adjustable inflatable protective structure, belonging to the field of functional clothing technology. Background Technology

[0002] As everyday clothing, regular jackets are primarily designed for wind protection, warmth, lightweight comfort, and ease of movement. However, with the increasing popularity of outdoor sports and travel, users' functional needs for jackets are gradually rising, including the desire for protection, support, or adjustability.

[0003] However, existing jackets fall short in meeting the demands for sports protection, posture support, and a balance between portability and comfort. Ordinary jackets lack dynamic support and cushioning for critical areas such as the neck and waist, and their functionality is limited. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a jacket with an adjustable inflatable protective structure to solve the problems of the existing technology.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: A jacket with an adjustable inflatable protective structure includes: a garment body, a neck air bladder sewn onto the neck of the garment body, and a waist air bladder sewn onto the waist of the garment body. The neck inflatable bladder is embedded with a gradient pressure diaphragm to form at least one independent pressure chamber. Each independent pressure chamber is interconnected, and a pressure equalization valve is provided at the connection point. An inflation assembly, wherein the inflation port of the inflation assembly is respectively provided with a valve body for controlling the airflow into the neck airbag and the waist airbag; The air input of the neck airbag and the waist airbag can be adjusted simultaneously or separately by means of the air inflator assembly and the valve body. By opening the valve, the gas discharge of the neck inflator and the waist inflator can be adjusted simultaneously or separately.

[0006] As a further improvement, the inflation assembly is a manually squeezed airbag. The air outlet of the manually squeezed airbag is provided with a first main tube, and two first branch tubes are connected to the main tube. One of the branch tubes is connected to the neck airbag, and the other branch tube is connected to the waist airbag.

[0007] As a further improvement, the valve body includes a manual valve, which is mounted on a branch conduit. The manual valve includes a collar mounted on the first branch conduit and a guide rod rotatably mounted on the collar. The guide rod has a first through hole in the transverse direction and a second through hole in the longitudinal direction. The first through hole is located above the second through hole and the two are interconnected. A knob is fixedly mounted above the guide rod. By pressing down the guide rod, the first through hole is made to open the channel connecting the first branch conduit and the first main conduit. By pulling up the guide rod, the first through hole and the first branch guide tube are misaligned, thus closing the communication channel between the first branch guide tube and the first main guide tube; By rotating the knob, the guide rod is driven to rotate 90°, so that the second through hole connects the first branch guide tube and the first main guide tube, and connects the second through hole with the first through hole and the external space, so as to discharge the gas in the first branch guide tube.

[0008] As a further improvement, the inflation component is an electric air pump, the valve body is a dual-control solenoid valve, the output end of the dual-control solenoid valve is connected to the electric air pump through a second main pipe, and the output end of the dual-control solenoid valve is connected to the neck inflation bladder and the waist inflation bladder through two second branch pipes respectively. It also includes a control module, which is electrically connected to the electric air pump and the dual-control solenoid valve. The control module works with the electric air pump to start and stop, and controls the inflation volume of the second main pipe. The control module controls the dual-control solenoid valves to connect / block the second branch conduits connecting the neck inflator and the waist inflator, respectively or simultaneously, thereby controlling the inflation and deflation of the neck inflator and the waist inflator.

[0009] As a further improvement, it also includes air pressure detection modules installed inside the neck inflator and the waist inflator, respectively, and the air pressure detection modules are electrically connected to the control module.

[0010] As a further improvement, a pressure sensor array is provided on the inner back side of the garment body. The sensor wires are woven into the conductive fiber layer and connected to the control module. The control module works with the air pressure detection module and the pressure sensor array to dynamically adjust the air pressure of the inflatable bladder.

[0011] As a further improvement, a detachable portable power source placed inside the garment body is also included, which is electrically connected to the control module and the electric air pump.

[0012] As a further improvement, the pressure equalization valve automatically opens to divert flow when the pressure difference in the cavity is ≥0.5kPa.

[0013] Beneficial effects: This invention utilizes an inflatable component to provide dynamic support for the neck and lower back during use. It overcomes the limitations of traditional rigid protective gear, enabling the protective structure to provide cushioning protection, such as dispersing impact during falls or collisions, while also allowing for adjustable inflation pressure to adapt to different activity intensities, such as providing lumbar support during cycling and neck relaxation during hiking, thus achieving on-demand switching between protective and comfortable states.

[0014] Existing inflatable protective gear generally suffers from uneven pressure distribution, leading to localized compression or insufficient support.

[0015] By integrating a gradient pressure diaphragm into the neck inflatable bladder, the bladder is divided into multiple independent pressure chambers, and dynamic airflow distribution is achieved through a pressure equalization valve.

[0016] Specifically, the neck airbag can be ergonomically designed with different initial pressure gradients in its cavities, such as high pressure at the back of the neck to support the cervical spine, and low pressure on the sides of the neck to maintain flexibility. When user movement causes local pressure changes, the equalization valve automatically adjusts the airflow between the cavities to avoid single-point overpressure or support failure. This significantly improves the fit and adaptability of the protective structure, resolving the contradiction of insufficient support rigidity or excessive pressure in traditional inflatable protective gear.

[0017] Traditional protective gear is inconvenient to store due to its fixed structure, while ordinary inflatable protective gear mostly uses a one-piece inflation design, which cannot achieve local adjustment. The neck and waist airbags are controlled by independent valves and operated by manual / electric inflation components.

[0018] Compared to traditional protective gear or single inflatable structures, by introducing the concept of gradient pressure distribution into clothing protective gear, and through multi-cavity design, it achieves zoned support combined with dynamic balance, rather than simply adding pressure; The linkage control logic between the valve body and the inflation component allows users to match different scenario needs through intuitive operations such as knob adjustment or APP control. With adjustable air pressure ranges, such as low pressure (10-20 kPa) for daily support and high pressure (30-50 kPa) for protection during strenuous exercise, this jacket covers a wider range of usage scenarios, avoiding the functional gaps that traditional protective gear may or may not have. It provides dynamic support and cushioning protection for critical areas such as the neck and lower back. Attached Figure Description

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model 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 utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0031] In the description of this utility model, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "multiple" means two or more, unless otherwise explicitly specified. Example

[0032] Reference Figure 1-4 As shown, a jacket with an adjustable inflatable protective structure includes: 1. A neck airbag sewn onto the neck of the garment body 1; 2. A waist airbag sewn onto the waist of the garment body 1; 3. The neck inflatable bladder 2 is embedded with a gradient pressure diaphragm 21 to form at least one independent pressure chamber 22. Each independent pressure chamber 22 is interconnected, and a pressure equalization valve 23 is provided at the connection point. An inflation assembly, wherein the inflation port of the inflation assembly is respectively provided with a valve body for controlling the airflow into the neck airbag 2 and the waist airbag 3. By using the inflation assembly in conjunction with the valve body, the gas input of the neck inflation bladder 2 and the waist inflation bladder 3 can be adjusted simultaneously or separately. By opening the valve, the gas discharge of the neck inflator 2 and the waist inflator 3 can be adjusted simultaneously or separately.

[0033] Traditional jackets rely on fixed padding or rigid protective gear, resulting in limited protection areas and stiff fit. The flexible embedding design of the neck air bladder 2 and waist air bladder 3 allows them to completely conform to the garment body 1 when deflated, maintaining the jacket's lightweight characteristics. When in use, the air component is pressurized to create dynamic support for the neck and waist. It breaks through the limitations of traditional rigid protective gear, allowing the protective structure to provide cushioning protection, such as dispersing impact force in the event of a fall or collision, and to adapt to different activity intensities through air pressure adjustment, such as providing lumbar support during cycling and decompression and relaxation of the neck during hiking, achieving on-demand switching between protective and comfortable states.

[0034] Existing inflatable protective gear generally suffers from uneven pressure distribution, leading to localized compression or insufficient support.

[0035] By integrating a gradient pressure diaphragm 21 into the neck inflatable bladder 2, the bladder is divided into multiple independent pressure chambers 22, and dynamic airflow distribution is achieved through a pressure equalization valve 23.

[0036] Specifically, the neck inflatable bladder 2 can be ergonomically designed with different initial pressure gradients in its cavities, such as high pressure at the back of the neck to support the cervical spine, and low pressure on the sides of the neck to maintain flexibility. When user activity causes local pressure changes, the equalization valve automatically adjusts the airflow between the cavities to avoid single-point overpressure or support failure. This significantly improves the fit and adaptability of the protective structure, resolving the contradiction of insufficient support rigidity or excessive pressure in traditional inflatable protective gear.

[0037] Traditional protective gear is inconvenient to store due to its fixed structure, while ordinary inflatable protective gear mostly uses a one-piece inflation design, which cannot achieve local adjustment. The neck and waist airbags 3 are controlled by independent valves and operated by manual / electric inflation components.

[0038] Compared to traditional protective gear or single inflatable structures, by introducing the concept of gradient pressure distribution into clothing protective gear, and through multi-cavity design, it achieves zoned support combined with dynamic balance, rather than simply adding pressure; The linkage control logic between the valve body and the inflation component allows users to match different scenario needs through intuitive operations such as adjustment by knob 435 or control via APP. By adjusting the air pressure range, such as low pressure 10-20kPa for daily support and high pressure 30-50kPa for protection during strenuous exercise, it covers more usage scenarios and avoids the functional gaps that traditional protective gear may or may not have.

[0039] In this embodiment, the inflation component is a manually squeezed airbag 4. The air outlet of the manually squeezed airbag 4 is provided with a first main tube 41, and two first branch tubes 42 are connected to the main tube. One of the branch tubes is connected to the neck airbag 2, and the other branch tube is connected to the waist airbag 3.

[0040] The valve body includes a manual valve 43, which is mounted on a branch conduit.

[0041] The manual valve 43 includes a collar 431 mounted on the first branch conduit 42 and a guide rod 432 rotatably mounted on the collar 431. The guide rod 432 has a first through hole 433 in the transverse direction and a second through hole 434 in the longitudinal direction. The first through hole 433 is located above the second through hole 434 and the two are connected to each other. A knob 435 is fixedly mounted on the top of the guide rod 432. By pressing down the guide rod 432, the first through hole 433 is made to open the channel connecting the first branch conduit 42 and the first main conduit 41. By pulling up the guide rod 432, the first through hole 433 is misaligned with the first branch guide tube 42, thus closing the communication channel between the first branch guide tube 42 and the first main guide tube 41. By rotating the knob 435, the guide rod 432 is driven to rotate 90°, so that the second through hole 434 connects the first branch guide tube 42 and the first main guide tube 41, and connects the second through hole 434 with the first through hole 433 and the external space, so as to discharge the gas in the first branch guide tube 42.

[0042] By employing a manually squeezed airbag 4 as the inflation component, the dependence of the electric air pump on batteries or external power sources is completely avoided, making it particularly suitable for outdoor and travel scenarios where electricity is inconvenient. Its physical squeezing action is directly converted into air pressure output, resulting in high energy conversion efficiency, and its simple structure and low failure rate.

[0043] The first main tube 41 and the first branch tube 42, in conjunction with the manual valve 43, provide the physical pathway for simultaneous inflation of the neck and waist, as well as independent adjustment of inflation to a single airbag. This satisfies both the need for rapid overall pressurization, such as pre-inflation before exercise, and supports localized fine-tuning, such as strengthening only the waist support, adapting to different usage scenarios.

[0044] Traditional inflation devices typically require multiple valves, such as inflation valves, deflation valves, and check valves, to achieve function switching. However, by using the downward / upward / rotational action of the guide rod 432, all three core operations can be completed with a single mechanical valve. Press down the guide rod 432: The first transverse through hole 433 aligns with the main guide tube and the branch guide tube to open the inflation channel; Pull up the guide rod 432: the through hole is misaligned, cutting off the gas flow and locking the current gas pressure; Rotating guide rod 432: The longitudinal second through hole 434 connects the branch guide tube to the external space, forming an exhaust channel.

[0045] This design significantly reduces the number of valves, simplifies the user's operating logic, and avoids inflation failure caused by misoperation of multiple valves.

[0046] The linkage between knob 435 and conductor rod 432 utilizes physical rotation and pressing actions. Users can directly perceive the valve status through touch and displacement changes; for example, changes in pressing resistance indicate on / off switching, and rotating the locking point indicates the activation of exhaust mode, without relying on an electronic display or audible prompts. Furthermore, the mechanical alignment structure of the through hole has strong anti-interference capabilities, maintaining a stable connection even in bumpy environments such as cycling or hiking.

[0047] Users can adjust the airbag pressure by quickly pressing down / rotating, such as when they suddenly need to strengthen lumbar support during exercise, or when they need to quickly release pressure after a fall. The response speed is much faster than electronic control systems that require waiting for the electric pump to start, making it especially suitable for high-risk sports scenarios. Example

[0048] Reference Figure 5-6 As shown in Figure 9, this embodiment is basically the same as embodiment 1, except that the inflation component is an electric air pump 5, the valve body is a dual-control solenoid valve 51, the output end of the dual-control solenoid valve 51 is connected to the electric air pump 5 through a second main pipe 52, and the output end of the dual-control solenoid valve 51 is connected to the neck inflation bag 2 and the waist inflation bag 3 through two second branch pipes 53 respectively. It also includes a control module 6, which is electrically connected to the electric air pump 5 and the dual-control solenoid valve 51. The control module 6 and the electric air pump 5 work together to start and stop, controlling the inflation volume of the second main pipe. The control module 6 controls the dual-control solenoid valve 51 to connect / block the second branch conduit 53 connecting the neck inflator 2 and the waist inflator 3, respectively or simultaneously, thereby controlling the inflation and deflation of the neck inflator 2 and the waist inflator 3.

[0049] As a further improvement, a detachable power supply 7 is also included, which is placed in the garment body 1 and is electrically connected to the control module 6 and the electric air pump 5.

[0050] This embodiment, while retaining the core functions of the original inflatable protective structure, solves the limitations of manual operation through electrification upgrades and intelligent control integration.

[0051] Manually squeezing the airbag 4 relies on physical operation by the user, resulting in slow inflation speed, high physical exertion, and reliance on experience for pressure control. Using an electric air pump 5 achieves the following: Inflates quickly, pressurizing the neck and waist airbags within seconds, avoiding the hassle of repeated manual squeezing; Constant pressure output: Through the linkage between the built-in pressure sensor and the control module 6, the set air pressure value such as 30kPa is precisely maintained to avoid overcharging or undercharging during manual operation. With one-button start, users can inflate the device simply by touching a button, making it especially suitable for one-handed operation during exercise or for the elderly and people recovering from injuries.

[0052] Compared to the mechanical on / off switching of the manual valve 43, the dual-control solenoid valve 51 controls the gas path switching via electrical signals, offering the following advantages: Micrometer-level response speed, millisecond-level switching of the on / off state of the sub-conduit, and support for complex inflation logic such as alternating inflation to simulate muscle contraction; Multi-mode control: The control module 6 is programmable and can be set with various inflation strategies such as progressive pressurization and periodic pulse inflation to improve the dynamic performance of protection. With bidirectional airflow capability, it not only controls inflation but also enables active deflation through reverse airflow, shortening the depressurization time, such as releasing airbag pressure within 0.5 seconds after a fall.

[0053] The control module 6 acts as the system brain. Through pressure closed-loop control, it monitors the pressure inside the airbag in real time and dynamically adjusts the power of the inflation pump to compensate for pressure fluctuations caused by temperature or activity. Multiple inflation parameters are pre-stored, such as cycling mode to enhance lumbar support and skiing mode to simultaneously pressurize the neck and waist. Users can switch between these modes with a single button or APP. In the future, it can be expanded to include heart rate and motion sensors, automatically increasing support and adjusting protection intensity based on the user's physiological state, such as fatigue.

[0054] The modular power supply and detachable power bank 7 design take into account both the energy consumption requirements of the electric system and the portability of clothing. It adopts a universal Type-C interface, supports fast charging and third-party power supply replacement, and avoids the built-in battery affecting the washing and maintenance of clothing. The control module 6 activates the solenoid valve and pump body only during inflation / deflation, with standby power consumption of less than 0.1W, extending battery life and supporting 5 hours of continuous adjustment in typical usage scenarios; Example

[0055] Reference Figure 7 , 9 As shown, this embodiment is a further improvement on embodiment 2, and also includes an air pressure detection module 54 installed inside the neck airbag 2 and the waist airbag 3 respectively. The air pressure detection module 54 is electrically connected to the control module 6.

[0056] As a further improvement, a pressure sensor array 58 is provided on the inner back side of the garment body 1. The sensor wires are woven into the conductive fiber layer 55 and connected to the control module 6. The control module 6 works with the air pressure detection module 54 and the pressure sensor array 58 to dynamically adjust the air pressure of the inflatable bag.

[0057] As a further improvement, the pressure equalization valve 23 automatically opens to divert flow when the pressure difference in the cavity is ≥0.5kPa.

[0058] By introducing a pressure detection module 54, a pressure sensor array 58, and a dynamic pressure equalization valve 23, a sensing-feedback-adjustment closed-loop system is constructed, achieving a leap from passive inflation control to active intelligent adjustment. This design addresses the core pain points of traditional inflatable protective gear from three dimensions: safety, accuracy, and adaptability.

[0059] By embedding miniature pressure sensors inside the neck and waist inflatable bladders 3, the absolute pressure values ​​of each bladder, such as the 0-50 kPa range and the rate of pressure change, can be monitored in real time. The control module 6, based on preset thresholds such as a safe range of 20-40 kPa, triggers a protection mechanism when pressure exceeds the limit. When the pressure of a certain airbag is ≥40kPa, the electric pump will be automatically shut off and the solenoid valve will be opened to release air, preventing excessive local compression. If the airbag pressure drops to ≤15kPa due to air leakage or user action, the system will automatically start the inflation pump to replenish the pressure and maintain the effectiveness of the protection.

[0060] Traditional electric inflation solutions rely on fixed intervals or manual user intervention, while the air pressure detection module 54 provides real-time pressure data input, enabling the control module 6 to dynamically adjust the inflation strategy according to actual needs. For example: When the user's heart rate rises, the pressure of the lumbar airbag is automatically increased, for example, from 25 kPa to 35 kPa, to enhance support. When changes in ambient temperature cause the gas to expand and contract due to heat, the inflation volume is finely adjusted through pressure feedback to maintain the set pressure value.

[0061] By integrating a flexible pressure sensor array 58, such as a piezoresistive sensor made of carbon nanotubes or graphene, into the inner back of the garment and weaving it into the garment structure through a conductive fiber layer 55, the pressure distribution pattern of the user's back can be captured in real time. This overcomes the limitation of traditional inflatable protective gear that relies solely on airbag pressure control, achieving: By analyzing changes in pressure distribution, it can be determined whether the user is in a state of bending over, sitting for a long time, or carrying heavy loads. When a local pressure ≥2kPa is detected, such as at the pressure point of the backpack strap, the pressure of adjacent airbags is automatically adjusted to distribute the load. It can provide posture correction feedback for patients with scoliosis and lumbar muscle strain, such as displaying a pressure heat map through the APP.

[0062] When it is detected that the user's prolonged sitting has caused uneven pressure distribution in the lower back, the pressure gradient of the neck and lower back airbags is adjusted simultaneously, such as increasing the pressure in the lower back by 5 kPa and reducing the pressure in the neck by 2 kPa to balance the force on the spine. It should be noted that the device structure and accompanying drawings of this utility model mainly describe the principle of this utility model. In terms of the technical aspects of this design principle, the setting of the power mechanism, power supply system and control system of the device is not fully described. However, under the premise that those skilled in the art understand the principle of the above utility model, the specific details of its power mechanism, power supply system and control system can be clearly understood. The control method in the application document is automatic control through a controller. The control circuit of the controller can be implemented by those skilled in the art through simple programming. All standard parts used can be purchased from the market, and can be customized according to the instructions and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the existing technology. The machinery, parts and equipment adopt conventional models in the existing technology, and the structure and principle of the components known to those skilled in the art can be known by those skilled in the art through technical manuals or conventional experimental methods.

Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
