Description

Technical Field

[0001] This invention relates to the field of anti-fall vest technology, specifically an anti-fall vest for the elderly with a hip airbag. Background Technology

[0002] Currently, fall prevention products for the elderly have evolved from basic physical protection to active protection systems integrating sensors and intelligent algorithms. Existing technologies mainly monitor human movement through inertial measurement units, combine this with artificial intelligence algorithms to predict fall risk, and instantly trigger airbag deployment upon detecting a fall.

[0003] However, existing protective vests lack precise standards for pressure control. Insufficient inflation results in weak protection, while excessive inflation may cause secondary injuries to elderly people with osteoporosis. Furthermore, traditional airbag reset mechanisms are complex, making it impossible to achieve quick storage and reuse, and there is a lack of zoned cushioning optimization for the head and hips. Summary of the Invention

[0004] The purpose of this invention is to provide a fall-prevention vest for the elderly with a hip airbag, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a fall-prevention vest for the elderly with a hip airbag, comprising a front vest, a back vest provided on one side of the front vest, the back vest comprising a plurality of compression bladders arranged in a longitudinal array, four symmetrically positioned air holes fixed between each pair of adjacent compression bladders, and a plurality of exhaust ropes fixed to both sides of the back vest and the front vest, and each exhaust rope being connected to a compression bladder at a corresponding position; The front vest has an inflatable structure inside its cavity, which can inflate the compression bladder through an exhaust rope. The back vest has two symmetrically positioned air tubes fixed to both the top and bottom ends. One end of each of the two air tubes at the same end is fixed to a shell. Each shell has a protective bladder inside its cavity, and each protective bladder is connected to the corresponding air tube. The back vest has an air bladder reset structure inside. A tray module is provided on one side of the compression bladder.

[0006] Preferably, the airbag reset structure includes a pull cord, which is fixed to the top of the inner cavity of each protective bladder, and each pull cord is inserted into the cavity of the corresponding air hole, and the other end of each pull cord passes through the outer wall of the back vest.

[0007] Preferably, an L-shaped connecting plate is fixedly connected to both the upper and lower ends of the back vest, and each L-shaped connecting plate is slidably connected to a pull rope at a corresponding position. Two rope boxes at symmetrical positions are fixedly connected to the side of each L-shaped connecting plate away from the front vest.

[0008] Preferably, each of the rope boxes has a fixed shaft rotatably connected inside its cavity, a coiled rope is wound around the outside of the fixed shaft, and the other end of the coiled rope is connected to a pull rope. A turntable is rotatably connected to the outer wall of the rope box on the side away from the compression bladder, and the turntable is fixedly connected to the fixed shaft.

[0009] Preferably, two symmetrically positioned electric actuators are fixedly connected to the bottom of the inner cavity of each protective bladder near the slot of the inflation tube. Each electric actuator has a clamping plate fixedly connected to its output end, and the two adjacent clamping plates can clamp the pull rope at the corresponding position.

[0010] Preferably, the inflation structure includes two compressed air cylinders, which are symmetrically installed on the outer side wall of the front vest. The front vest has two symmetrically positioned air supply channels inside, and the air supply channels are connected to the exhaust rope.

[0011] Preferably, an electric valve is installed at the slot of the compressed gas cylinder, and the electric valve is connected to the gas supply channel. Two air pumping pipes are installed on the outer side wall of the front vest, and each air pumping pipe is connected to the compressed gas cylinder at the corresponding position.

[0012] Preferably, the pallet module includes a sliding base, on the side of the sliding base near the back vest, two electric sliding plates of different sizes are slidably connected, and each electric sliding plate is provided with two drive disks at the end away from the sliding base, and each drive disk can be plugged into a turntable at a corresponding position.

[0013] Compared with the prior art, the beneficial effects of the present invention are: Controlled by an electric valve, a compressed gas cylinder rapidly inflates the compression bladder through an air supply channel and an exhaust rope, creating initial cushioning. Simultaneously, an electric actuator drives a clamp to release a pull rope, allowing high-pressure gas to instantly fill the protective bladder through the inflation tube, providing effective protection for critical areas such as the head and hips. The rope coil and fixing shaft inside the rope box ensure smooth release of the pull rope during bladder inflation, avoiding interference. Afterward, the pull rope can be retracted via a turntable, returning the protective bladder to its original position within the outer shell. Inflation can then be completed using the air inflator, enabling the protective bladder to be reused. Furthermore, a tray module coordinates with a drive plate to drive a turntable, and after deflation, the deflated bladder's properties guide the automatic folding of the back and front vests, significantly reducing storage volume and improving portability and storage convenience. Through the combination of pneumatic control and mechanical linkage, multi-level protection is triggered upon a fall, effectively reducing the risk of fractures while maintaining ease of use and cost-effectiveness.

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Please see Figures 1-11The present invention provides a technical solution: a fall protection vest for the elderly with a hip airbag, including a front vest 13, a back vest 23 on one side of the front vest 13, the back vest 23 including a number of compression bladders 1 arranged in a longitudinal array, four symmetrical air holes 2 fixed between each two adjacent compression bladders 1, and a number of exhaust ropes 14 fixed together on both sides of the back vest 23 and the front vest 13, and each exhaust rope 14 is connected to the compression bladder 1 at the corresponding position; The front vest 13 has an inflatable structure inside its cavity, which can inflate the compression bladder 1 through the exhaust rope 14. Two symmetrically positioned inflation tubes 31 are fixed to both the upper and lower ends of the back vest 23. One end of each of the two inflation tubes 31 at the same end is fixed to a shell 9. Each shell 9 has a protective bladder 10 inside its cavity, and each protective bladder 10 is connected to the corresponding inflation tube 31. An air bladder reset structure is provided inside the back vest 23. A tray module 22 is provided on one side of the compression bladder 1.

[0018] Specifically, the front vest 13 is made of thick leather, and the compression bladder 1 is made of soft rubber, which can provide some cushioning and protection when the elderly fall. (See reference) Figure 2 The upper protective bladder 10 is used to protect the head of the elderly. When the elderly fall, the inflatable structure can inflate to protect the head. The lower protective bladder 10 is used to protect the hips of the elderly. When they fall, it will also inflate to protect the hips and prevent fractures.

[0019] In this embodiment, the airbag reset structure includes a pull cord 3, which is fixed to the top of the inner cavity of each protective bladder 10. Each pull cord 3 is inserted into the cavity of the corresponding air hole 2, and the other end of each pull cord 3 passes through the outer wall of the back vest 23.

[0020] In this embodiment, an L-shaped connecting plate 6 is fixedly connected to both the upper and lower ends of the back vest 23, and each L-shaped connecting plate 6 is slidably connected to the pull rope 3 at the corresponding position. Two rope boxes 4 are fixedly connected to the side of each L-shaped connecting plate 6 away from the front vest 13.

[0021] In this embodiment, a fixed shaft 7 is rotatably connected inside the cavity of each rope box 4. A coiled rope 5 is wound around the outside of the fixed shaft 7, and the other end of the coiled rope 5 is connected to the pull rope 3. A turntable 8 is rotatably connected to the outer wall of the rope box 4 on the side away from the compression bladder 1, and the turntable 8 is fixedly connected to the fixed shaft 7.

[0022] In this embodiment, two symmetrically positioned electric push rods 11 are fixedly connected to the bottom of the inner cavity of each protective bladder 10 near the slot of the inflation tube 31. Each electric push rod 11 has a clamping plate 12 fixedly connected to its output end, and the two adjacent clamping plates 12 can clamp the pull rope 3 at the corresponding position.

[0023] For details, please refer to Figure 1 and Figure 5 At this time, the protective bladder 10 is not opened, and the electric actuator 11 pushes the clamp 12 to clamp the corresponding pull rope 3. At this time, some of the gas inside the inflatable structure fills the back vest 23, causing the compression bladder 1 to inflate. However, the protective bladder 10 is restricted from inflating by the pull rope 3. When the elderly person falls, the electric actuator 11 will cause the clamp 12 to reset and no longer clamp the pull rope 3. At this time, the gas inside the inflatable structure will immediately cause the protective bladder 10 to inflate. During the inflating process, the protective bladder 10 will protect the elderly person's head and hips. Simultaneously, the inflating process of the protective bladder 10 will pull the pull rope 3. During the pulling of the pull rope 3, refer to... Figure 6 The coiled rope 5 inside the rope box 4 will be pulled out, causing the fixed shaft 7 and the turntable 8 to rotate rapidly, so that the pull rope 3 will not affect the expansion of the protective bladder 10.

[0024] In this embodiment, the inflation structure includes two compressed air cylinders 15, which are symmetrically installed on the outer side wall of the front vest 13. The front vest 13 has two symmetrically positioned air supply channels 17 inside, and the air supply channels 17 are connected to the exhaust rope 14.

[0025] In this embodiment, an electric valve 18 is installed at the slot of the compressed gas cylinder 15, and the electric valve 18 is connected to the gas supply channel 17. Two symmetrically positioned air pumping pipes 16 are installed on the outer side wall of the front vest 13, and each air pumping pipe 16 is connected to the compressed gas cylinder 15 at the corresponding position.

[0026] Specifically, when the protective bladder 10 needs to be reused after use, the turntable 8 can be rotated in the opposite direction to allow the rope 5 to be retracted into the rope box 4. At the same time, the protective bladder 10 will be pulled to fill the inside of the outer shell 9 again. Then, a high-pressure air pump is used from the outside to inflate the compressed air cylinder 15 through the air pumping pipe 16. During the inflation process, the electric valve 18 will be opened, so that air is pumped into the back vest 23 through the air supply channel 17 and the exhaust rope 14. The compressed air cylinder 15 stores high-pressure gas.

[0027] In this embodiment, the pallet module 22 includes a sliding seat 20. Two electric sliding plates 19 of different sizes are slidably connected to the side of the sliding seat 20 near the back cover 23. Each electric sliding plate 19 is provided with two drive disks 21 at the end away from the sliding seat 20, and each drive disk 21 can be plugged into the turntable 8 at the corresponding position.

[0028] Specifically, the pallet module 22 can be positioned when inflating the compressed gas cylinder 15. After the protective bladder 10 is used, the back cover 23 is placed on top of the two electric sliding plates 19, and each turntable 8 is inserted into the corresponding drive plate 21. Then, after the turntable 8 and drive plate 21 are inserted, if it is necessary to store the back cover 23 and the front cover 13, the compressed gas cylinder 15 and the back cover 23 must first be evacuated through the air pumping pipe 16. During the evacuation process, each compression bladder 1 on the back cover 23 and The protective bladder 10 will begin to deflate, and then the drive disc 21 will drive the turntable 8 to rotate. During the rotation, the protective bladder 10 will be pulled into the interior of the outer shell 9 by the pull rope 3. Then, as the compression bladder 1 deflates, the length of the back vest 23 will shorten. As the length of the back vest 23 shortens, it will cause the front vest 13 to bend and fold, thereby reducing the overall volume of the front vest 13 and the back vest 23, making it easier to store for later use. When needed, air can be pumped into the compressed air cylinder 15 through the air pumping pipe 16.

[0029] Working principle: When an elderly person accidentally falls, the control system immediately triggers the opening of the electric valve 18 on the compressed gas cylinder 15. High-pressure gas then quickly fills the compression bladder 1 in the back vest 23 through the gas supply channel 17 and the exhaust rope 14, causing it to expand and form initial cushioning. At the same time, the electric push rod 11 drives the clamp 12 to loosen the clamp on the pull rope 3, allowing the high-pressure gas to quickly flow into the protective bladder 10 inside the outer shell 9 through the inflation tube 31, causing it to quickly expand at key positions such as the head and hip to absorb impact energy. During the expansion of the protective bladder, the pull rope 3 is pulled, causing the coiled rope 5 in the rope box 4 to be released. The fixed shaft 7 and the turntable 8 rotate accordingly, ensuring that the protective bladder expands without obstruction. After use, the gas cylinder can be replenished through the air inflator 16, and the turntable 8 can be driven to rotate in the opposite direction by the drive disc 21 of the support module 22 to tighten the pull rope and reset the protective bladder for future use. Through the combination of mechanical linkage and pneumatic control, multi-level protection is achieved at the moment of fall, effectively reducing the risk of fractures in key areas such as the hip.

[0030] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
