Description

Technical Field

[0001] This invention relates to the field of low-altitude flight safety emergency rescue equipment technology, and in particular to a wearable inflatable emergency paraglider. Background Technology

[0002] With the increasing prevalence of low-altitude manned aircraft, the flight conditions are complex. In the event of a sudden malfunction at mid- or high-altitude altitudes, occupants need to be equipped with life-saving equipment for emergency landing and evasive landing.

[0003] Existing traditional paragliders rely on high altitudes and oncoming airflow to inflate and deploy, and are prone to instability and wing breakage in low-altitude turbulent environments; traditional parachute packs are bulky and complicated to wear, making it impossible to put them on and wait in the aircraft in advance; conventional emergency rescue parachutes can only decelerate and land vertically, without gliding obstacle avoidance capabilities; traditional tow ropes are mostly fixed-length loose structures, which are easy to tangle when stored and have a large impact when the parachute opens, resulting in significant deficiencies in safety and applicability.

[0004] To overcome the many shortcomings of existing technologies, this case proposes a wearable inflatable emergency paraglider, which adopts an integrated load-bearing vest, a shoulder-mounted accordion-style folding storage bag, an arc-shaped flat bottle air source on the outside of the thigh, a self-inflating wing-shaped paraglider body, and a spring tape measure-style elastic winding traction rope structure, to achieve a brand-new technical solution that can be worn daily, self-inflated, used at low altitudes, and allows for controllable gliding and hazard avoidance. Summary of the Invention

[0005] The purpose of this invention is to provide a wearable inflatable emergency paraglider that solves the problems of existing paragliders, such as dependence on airflow, inconvenience of wearing, inability to be positioned in advance, easy entanglement, large impact, and lack of controllable gliding and obstacle avoidance capabilities. It achieves the effects of being able to be worn close to the body for a long time, self-inflating and forming, suitable for low-altitude use, dual redundant safety triggering, and controllable gliding and fixed-point landing.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A wearable inflatable emergency paraglider includes a one-piece support vest, a shoulder-mounted accordion-style folding storage bag, an inflatable wing-shaped paraglider body, an arc-shaped flat bottle high-pressure air source assembly, an intelligent triggering system, a spring tape measure-style elastic winding traction rope assembly, and a gliding manual control mechanism.

[0007] The main body of the one-piece support vest is a front-opening one-piece wearable structure. The whole body is made of high-strength and wear-resistant fabric. Reinforced webbing and reinforced stitching are set at key load-bearing positions. It is equipped with multiple adjustable straps to adapt to people of different body types. The load-bearing distribution is even, and it is comfortable to wear without restricting limb movement.

[0008] The shoulder-mounted accordion-style folding storage bag is integrated into the back of the one-piece support vest. Its shape conforms to the contour of the human back, and its appearance is similar to an ordinary backpack. It is highly concealed and can be worn for a long time in the cockpit of an aircraft. The storage compartment is equipped with an elastic restraint and limiting structure. The inflatable wing-shaped paraglider can be neatly stored after folding. In case of emergency deployment, it can easily break free of restraint and quickly unfold.

[0009] The high-pressure air source components of the arc-shaped flat bottle are arranged symmetrically in pairs and fitted to the outside of the human thigh. The bottle body adopts an arc-shaped flat shape that imitates the curve of the human leg. The inner side fits the leg shape and the outer side is smoothly transitioned. It is fixed with a special bracket and limiting strap. The overall design is not obtrusive and does not affect walking, squatting or riding posture. The high-pressure air source components are connected to the inflatable wing-shaped paraglider body through a hidden pipeline, which can quickly provide inflation pressure to the paraglider body.

[0010] The inflatable wing-shaped paraglider body is made of multi-layer composite airtight tear-resistant flexible fabric, with an internal interconnected inflatable frame pipeline structure; after being filled with gas by a high-pressure gas source, it can automatically and quickly solidify to form a stable aerodynamic wing structure, which can be formed and deployed without relying on external oncoming airflow, and has strong resistance to turbulence and collapse.

[0011] The intelligent triggering system integrates attitude sensing and height detection modules, which can identify fall and height conditions in real time; it is also equipped with an independent mechanical manual triggering structure, forming dual redundancy protection of automatic sensing triggering and manual emergency triggering; the system is equipped with a ground safety locking structure, which locks all triggering actions when worn on the ground, effectively avoiding accidental triggering.

[0012] The spring-loaded elastic retractable traction rope assembly is symmetrically arranged on the left and right sides of the vest's chest. It includes a sealed, dustproof retractable box, a spiral spring mandrel, a high-strength traction belt, damping components, and a travel limit structure. The spiral spring mandrel is rotatably mounted inside the retractable box. One end of the traction belt is wound and fixed to the mandrel, while the other end extends from the retractable box outlet and connects to the paraglider's load-bearing point. In the non-working state, the traction belt is completely retracted and stored inside the retractable box under the action of the spiral spring, with no exposed loose rope, preventing entanglement with parachute lines, tubing, or straps. During parachute deployment, the spring and damping work together to form a flexible buffer, reducing the instantaneous impact of parachute opening and protecting the torso. During gliding, the traction belt automatically retracts and expands to compensate for changes in parachute attitude, maintaining appropriate tension at all times without affecting gliding control precision. After landing, excess rope is automatically retrieved to prevent dragging and tripping injuries.

[0013] The manual gliding control mechanism is located on the chest and includes a control handle and corresponding control ropes. The control ropes are connected to the left and right rear edges of the inflatable wing-shaped paraglider. By manually pulling the ropes, gliding turns, pitch adjustments, and deceleration altitude control can be achieved. The operation logic is simple and easy to master. Beneficial effects

[0014] Compared with the prior art, the present invention has the following advantages: It adopts an integrated one-piece vest and a shoulder-mounted accordion-style folding storage bag structure, which can be worn close to the body as a normal routine. Its appearance is neat and unobtrusive. It can be worn and ready for use in the aircraft for a long time. It can be used immediately in case of emergency without the need for temporary preparation.

[0015] It adopts a flat, arc-shaped air source layout on the outer thigh, which conforms to the curve of the human body and has a reasonable center of gravity distribution. It does not compress or interfere with limb movements, overcoming the shortcomings of traditional air cylinders that are bulky to carry and cause pressure when sitting for long periods of time.

[0016] The umbrella body adopts a high-pressure self-inflating and forming structure, which does not rely on the oncoming airflow. It can be smoothly formed and deployed under low-altitude, low-speed, and stationary conditions, with a wider applicable height range and better resistance to turbulence.

[0017] Equipped with automatic sensing and dual mechanical / manual triggering, plus ground safety locking, multiple layers of protection against accidental activation and high reliability, meeting emergency rescue safety requirements.

[0018] Equipped with a spring-loaded elastic retractable traction rope, it achieves multiple functions such as automatic storage, anti-tangling, parachute opening cushioning, adaptive tensioning during gliding, and automatic retrieval upon landing, solving the problems of traditional ropes being loose and easy to tangle, causing large impacts, and making it easy to trip over again.

[0019] Equipped with a simple manual gliding control mechanism, it can turn, avoid obstacles, and choose a landing spot, lowering the barrier to entry and allowing non-professionals to complete basic emergency gliding and hazard avoidance operations.

[0020] With its modular structure, it is easy to disassemble and maintain, reusable, and adaptable to various emergency rescue applications such as low-altitude aircraft and high-altitude operations, making it highly practical for widespread adoption. Detailed Implementation

[0021] The present invention will be further described in detail below with reference to the embodiments.

[0022] A wearable inflatable emergency paraglider includes a one-piece support vest, a shoulder-mounted accordion-style folding storage bag, an inflatable wing-shaped paraglider body, an arc-shaped flat bottle high-pressure air source assembly, an intelligent triggering system, a spring tape measure-style elastic winding traction rope assembly, and a gliding manual control mechanism.

[0023] The main body of the one-piece support vest is made of high-strength and wear-resistant fabric. It has a front-opening design and adjustable load-bearing straps at the chest, waist, and hips. Key stress areas are reinforced with stitching to fit the average adult height and body type.

[0024] The shoulder bag features a lightweight, rigid shell that conforms to the streamlined shape of the back and is secured to the back of the vest. It has an internal elastic strap to restrain the folded wing-shaped umbrella and releases naturally when the umbrella is opened and subjected to force.

[0025] The high-pressure air source component in the arc-shaped flat bottle is symmetrically installed on the outside of the thigh. The bottle body has an arc-shaped flat biomimetic shape, with a smooth outer side and an inner side that conforms to the curve of the leg. It is fixed by a special bracket and strap, and is equipped with an external cushioning and protective structure. The high-pressure pipeline is hidden inside the vest layer, connecting the air source to the umbrella inflation interface.

[0026] The inflatable wing-shaped paraglider body is made of composite airtight and tear-resistant fabric, with an internally connected inflatable frame tube. After inflation, it autonomously forms a stable wing-shaped structure, possessing excellent hang time and gliding capabilities.

[0027] The intelligent triggering system integrates attitude sensing and altitude detection modules, and has built-in fall detection logic to automatically start inflation when the working conditions are met; it also has an independent mechanical manual trigger pull ring to form dual redundancy protection; the system is equipped with a ground safety locking pin to prevent the parachute from being triggered to open when on the ground.

[0028] The spring tape measure type elastic winding traction rope assembly is fixed to both sides of the front of the vest. The winding box is a sealed dustproof structure with a spiral spring core and a damping limit structure inside. The high-strength traction belt is wound on the core and the outer end is connected to the stress point of the paraglider. It is completely rolled up and hidden in normal state, with flexible buffering when the parachute is open, adaptive tension when gliding, and automatic recovery upon landing.

[0029] The manual gliding control mechanism is located on the chest and is equipped with a control handle and two sets of control ropes on the left and right. The control ropes are connected to the trailing edge of the wing-shaped parachute and can be manually pulled to achieve turning, deceleration and gliding attitude adjustment.

[0030] Work process: The user dons the one-piece support vest, adjusts the tightness of the straps, secures the curved flat-bottomed air supply assembly to the outside of the thigh, and inserts the ground safety locking mechanism to sit normally inside the aircraft. In the event of a sudden malfunction and loss of control during flight, the intelligent triggering system identifies the fall and altitude conditions, automatically controlling the air supply to rapidly inflate the wing-shaped parachute, causing it to detach and deploy from the back storage compartment. Simultaneously, the waist-side traction rope is smoothly released and provides cushioning, initiating a stable gliding state. The user can adjust the gliding direction and attitude using the manual control mechanism on their chest, avoiding obstacles and choosing a safe landing area. If the automatic system fails, the user can manually pull the trigger ring to open the emergency parachute. After landing, the traction rope automatically retracts into the box, with no excess rope dragging on the ground. Attached Figure Description
