Description

Technical Field

[0001] This utility model relates to the field of rescue air cushion technology, specifically a rescue air cushion that is easy to transport. Background Technology

[0002] Rescue air cushions, as key equipment for fall protection, are widely used in fire rescue, construction safety, and emergency escape scenarios. Their core function is to reduce the impact of falls from heights through the cushioning effect of inflated airbags, ensuring life safety. With the increasing complexity and urgency of rescue scenarios, the portability, deployment speed, and storage efficiency of rescue air cushions have become core directions for technological improvement.

[0003] Traditional rescue air cushions have bulky airbags that require manual folding for storage, which is time-consuming and labor-intensive. Even when folded, they remain large and difficult to move quickly. Especially in emergency rescues, low transport efficiency can lead to delays in rescue efforts. Some air cushions use rigid housings for storage, but the method of securing the airbags to the housing is complex, requiring multiple people to work together during deployment, making the operation cumbersome. Utility Model Content

[0004] The purpose of this invention is to provide a rescue air cushion that is easy to transport, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rescue air cushion that is easy to transport, comprising a box body, an airbag cushion, and a movable plate. The box body has an internal cavity, and one side of the box body has a slot communicating with the cavity. The upper and lower ends of the slot are respectively equipped with roller shaft one and roller shaft two via rotating shafts. A servo motor is installed at one end of the box body. The output end of the servo motor extends to the center inside the cavity and is equipped with a central shaft. The airbag cushion is wrapped around the outside of the central shaft via a connecting belt one. The other end of the airbag cushion extends through the slot to the outside of the box body and is equipped with a movable plate via a connecting belt two.

[0006] The airbag cushion is evenly divided into partitioned air chambers. One end of each partitioned air chamber is connected to the central axis through a connecting pipe, and the other end of each partitioned air chamber is connected to the exhaust pipe on the movable plate through a connecting pipe.

[0007] Preferably, the central shaft has an inflation channel inside, and one end of the box has an inflation hole connected to the inflation channel, with a sealing plug on the outside of the inflation hole.

[0008] Preferably, each of the connecting pipes is connected to the inflation channel, and the connecting pipes are arranged side by side inside the interlayer of the connecting strip.

[0009] Preferably, the two connecting pipes are arranged side by side inside the interlayer of the two connecting strips, and a sealing cap can be detachably installed on the outside of the exhaust pipe at the output end of each of the two connecting pipes.

[0010] Preferably, rollers are installed at both corners of one end of the box, legs are provided at the other two corners of one end of the box, and a handle is provided at the edge of the other end of the box.

[0011] Preferably, the bottom of the airbag cushion is provided with an anti-slip mat.

[0012] Preferably, the first roller and the second roller are located on the upper and lower sides of the airbag cushion, respectively.

[0013] This utility model provides a rescue air cushion that is easy to transport, and compared with the prior art, it has significant advantages, specifically reflected in the following aspects:

[0014] 1. By placing a central shaft inside the cavity of the housing and winding the airbag cushion around it, the airbag cushion can be quickly deployed and retracted using a servo motor driven by the central shaft. This design not only simplifies the operation process but also significantly shortens the deployment time of the rescue airbag, improving rescue efficiency. The other end of the airbag cushion passes through a slot and extends to the outside of the housing, connecting to a movable plate. During use, simply pulling the movable plate allows the airbag cushion to be easily pulled out and deployed, simplifying the operation and avoiding the cumbersome steps involved in deploying traditional rescue airbags.

[0015] 2. The airbag cushion is evenly divided into partitioned air chambers. Each partitioned air chamber is connected to the inflation channel inside the central shaft via a connecting pipe 1. Rapid inflation through the inflation holes ensures uniform expansion of all parts of the airbag cushion, improving its stability and safety. The other end of each partitioned air chamber is connected to an exhaust pipe on the movable plate via a connecting pipe 2. A detachable sealing cap is installed on the outside of the exhaust pipe. After use, opening the sealing cap allows the servo motor to drive the central shaft to rotate. Rollers 1 and 2 compress the airbag cushion, rapidly expelling internal air and significantly reducing storage time.

[0016] 3. The housing is equipped with wheels at one end and supports and a handle at the other. Combined with the compact size of the airbag after it is folded up, the entire rescue airbag is easy to handle and move, making it particularly suitable for emergency rescue situations and enabling rapid arrival at the rescue site. Through the squeezing action of roller one and roller two, the airbag volume is significantly reduced during the folding process, further improving the ease of handling.

[0017] 4. The bottom of the airbag is equipped with an anti-slip mat, which effectively prevents the airbag from sliding during use, enhancing the stability and safety of the rescue airbag and ensuring the safety of the rescued personnel. The partitioned air chamber design not only improves the efficiency of inflation and deflation but also enhances the overall structural strength of the airbag, enabling it to maintain good stability under different load conditions.

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0025] Please see Figure 1-5 One embodiment of this utility model is a rescue air cushion that is easy to transport, including a housing 1, an airbag 4 and a movable plate 7. A servo motor 16 is installed at one end of the housing 1. The output end of the servo motor 16 extends to the center inside the cavity 8 and is equipped with a central shaft 13. An inflation channel 20 is provided inside the central shaft 13, and an inflation hole 17 connected to the inflation channel 20 is provided at one end of the housing 1. A sealing plug 15 is provided on the outside of the inflation hole 17.

[0026] The housing 1 has a rectangular structure and is preferably made of high-strength plastic or metal to ensure its durability during handling and use. The housing 1 has an internal cavity 8 to accommodate the airbag cushion 4 and the movable plate 7. The inner wall of the cavity 8 is smooth to reduce friction on the airbag cushion 4 during deployment and retraction.

[0027] The servo motor 16 is mounted at one end of the housing 1, specifically at the top center of the housing 1. The output end of the servo motor 16 extends into the cavity 8 inside the housing 1 via a transmission device. The selection of the servo motor 16 should take into account its torque and speed to ensure that it can smoothly drive the central shaft 13 to rotate.

[0028] The central shaft 13 is located at the center of the cavity 8, and its material is preferably stainless steel to enhance its corrosion resistance and strength. An inflation channel 20 is provided inside the central shaft 13, which runs through the entire length of the central shaft 13. One end of the central shaft 13 is connected to the output end of the servo motor 16, and the other end extends to the outside of the housing 1 through the inflation hole 17.

[0029] An inflation port 17 is located at one end of the housing 1 and is connected to the inflation channel 20. A sealing plug 15 is installed on the outside of the inflation port 17, preferably made of rubber or silicone to ensure good sealing performance. The sealing plug 15 is designed to be easy to operate manually so that it can be quickly opened and closed when inflation or deflation is required.

[0030] The airbag 4 is placed inside the housing 1, and is preferably made of high-strength, wear-resistant rubber or synthetic material. The airbag 4 can be folded and stored inside the housing 1 when it is not inflated, and unfolds to form a stable support surface when inflated.

[0031] An airbag cushion 4 is wrapped around the outside of the central shaft 13 via a connecting belt 19.

[0032] The other end of the airbag cushion 4 extends through the slot 2 to the outside of the box body 1 and is equipped with a movable plate 7 via the connecting strap 18.

[0033] The bottom of the airbag cushion 4 is equipped with an anti-slip mat 3.

[0034] Connecting belt 19 is used to guide the airbag cushion 4 to be evenly wound on the central shaft 13.

[0035] The material of the connecting strip 19 is preferably high-strength nylon or other materials with good toughness and strength.

[0036] The slot 2 is located on the side wall of the housing 1 and is used to guide the extension of the airbag cushion 4.

[0037] The shape and size of the slot 2 should be designed to ensure that the airbag cushion 4 can pass through smoothly without being damaged by friction.

[0038] Connecting strap 2 18 is used to connect the other end of the airbag cushion 4 to the movable plate 7.

[0039] The material of connecting strip 2 18 is the same as that of connecting strip 1 19 to ensure the coordination and consistency of the overall structure.

[0040] The anti-slip mat 3 is placed at the bottom of the airbag mat 4 to increase the friction between the device and the ground and prevent slippage.

[0041] The material of the anti-slip mat 3 is preferably rubber or a similar material with good anti-slip properties.

[0042] The box 1 has an internal cavity 8, and a slot 2 connected to the cavity 8 is provided on one side of the box 1. Roller shaft 9 and roller shaft 10 are respectively installed at the upper and lower ends of the slot 2 through rotating shafts.

[0043] Roller 1 (9) and roller 2 (10) are located on the upper and lower sides of the airbag cushion 4, respectively.

[0044] The interior of the housing 1 is provided with a cavity 8, which is mainly used to accommodate and protect the folded airbag cushion 4.

[0045] A slot 2, which communicates with the cavity 8, is provided on one side of the housing 1. The slot 2 is designed to allow the airbag 4 to easily enter or exit the cavity 8. The size and shape of the slot 2 are designed according to actual usage requirements to ensure the smooth passage of items.

[0046] At the upper and lower ends of the inner side of the slot 2, roller shaft 9 and roller shaft 10 are respectively installed via rotating shafts. The main function of roller shaft 9 and roller shaft 10 is to support and guide the entry and exit of items, reduce the friction between the items and the slot 2, thereby improving the efficiency of use and extending the service life.

[0047] Specifically, roller 9 and roller 10 are located on the upper and lower sides of the airbag cushion 4, respectively. The roller 9 and roller 10 can be made of highly wear-resistant materials, such as stainless steel or high-hardness plastic, to ensure their stability and durability in long-term use.

[0048] The airbag cushion 4 is located between roller 9 and roller 10, and its main function is to provide cushioning and shock absorption after inflation.

[0049] The airbag cushion 4 is evenly provided with partitioned air chambers 22. One end of each partitioned air chamber 22 is connected to the central shaft 13 through a connecting pipe 1 23, and the other end of each partitioned air chamber 22 is connected to the exhaust pipe 5 provided on the movable plate 7 through a connecting pipe 21.

[0050] Each connecting pipe 23 is connected to the inflation channel 20, and the connecting pipes 23 are arranged side by side inside the interlayer of the connecting strip 19.

[0051] The connecting pipes 21 are arranged side by side inside the interlayer of the connecting strip 28, and the exhaust pipe 5 at the output end of each connecting pipe 21 is detachably fitted with a sealing cap 6.

[0052] The airbag cushion 4 has multiple evenly distributed partitioned air chambers 22 inside. This ensures that each partitioned air chamber 22 expands uniformly, improving the stability and safety of the airbag.

[0053] One end of each partitioned air chamber 22 is connected to the central shaft 13 via a connecting pipe 23. The function of the connecting pipe 23 is to connect the inflation channel 20 of the central shaft 13 to each partitioned air chamber 22, allowing gas to be transferred from the central shaft 13 to each partitioned air chamber 22. The connecting pipes 23 are arranged side by side inside the interlayer of the connecting strip 19, which is made of high-strength material to ensure that the connecting pipes 23 will not be damaged due to excessive pressure during inflation.

[0054] The other end of each partitioned air chamber 22 is connected to the exhaust pipe 5 provided on the movable plate 7 via a connecting pipe 21. The function of the connecting pipe 21 is to discharge the gas in the partitioned air chamber 22, thereby realizing the exhaust operation of the partitioned air chamber 22. The connecting pipes 21 are arranged side by side inside the interlayer of the connecting strip 18, which is also made of high-strength material to ensure that the connecting pipes 21 have good sealing and durability during the exhaust process.

[0055] Each connecting pipe 21 has a removable sealing cap 6 on the outside of its exhaust pipe 5. The sealing cap 6 is designed to tightly cover the outlet of the exhaust pipe 5 to prevent gas leakage. The sealing cap 6 is made of a soft and flexible material for easy installation and removal.

[0056] Rollers 11 are installed at both corners of one end of the box body 1, support legs 14 are provided at the other two corners of one end of the box body 1, and handles 12 are provided at the edge of the other end of the box body 1.

[0057] Rollers 11 are installed at the two corners of one end (e.g., the front end) of the housing 1. The rollers 11 are made of wear-resistant material and have good rolling performance and load-bearing capacity.

[0058] The roller 11 is connected to the housing 1 via a bearing to ensure smooth and stable rolling.

[0059] At the other two corners of the same end (i.e., the front end) of the housing 1, there are support legs 14. The support legs 14 are made of high-strength plastic or metal and have good support performance.

[0060] The design of the support leg 14 enables it to provide stable support when the box 1 is placed on the ground, preventing the box 1 from tilting due to the rolling of the roller 11.

[0061] A handle 12 is provided at the edge of the other end (e.g., the rear end) of the housing 1. The handle 12 is made of a soft and durable material, making it easy for the user to grip and drag the housing 1.

[0062] When this application embodiment is used,

[0063] Storage state structure

[0064] The airbag cushion 4 is wrapped around the outside of the central shaft 13 and stored in the cavity 8 of the box body 1.

[0065] The movable plate 7 is connected to the end of the airbag cushion 4 via connecting strap 2 18 and is located outside the slot 2; the sealing cap 6 of the exhaust pipe 5 is tightened. The rollers 11 and support feet 14 at the bottom of the box 1 support the equipment, and the handle 12 facilitates dragging and moving. The overall size is compact and suitable for rapid movement.

[0066] Transportation operations

[0067] Rescuers hold the handle 12 and push the container 1 to move using the rollers 11, adapting to terrains such as flat ground and slopes; the support legs 14 support the container when stationary to prevent it from rolling.

[0068] Airbag deployment and inflation

[0069] Rescuers pull the movable plate 7, causing the airbag cushion 4 to be pulled out from the slot 2. At this time, roller 9 and roller 10 rotate, reducing the resistance to deployment.

[0070] Simultaneously, the servo motor 16 is activated (which can be done via an external switch or remote control). The motor drives the central shaft 13 to rotate counterclockwise, releasing the wrapped airbag cushion 4 until it is fully deployed to the predetermined position (such as directly below the point of impact).

[0071] Open the sealing plug 15 of the inflation port 17, connect the inflation equipment (such as a high-pressure gas cylinder or electric pump), and the gas enters the connecting pipe 23 through the inflation channel 20.

[0072] The connecting pipe 23 evenly delivers gas to each zone air chamber 22. Since the zone air chambers are distributed in parallel, the airbag cushion 4 expands synchronously to form a stable support surface.

[0073] During inflation, the anti-slip mat 3 contacts the ground and uses the friction of the rubber material to fix the position of the air cushion and prevent it from sliding.

[0074] When a person falls onto the airbag cushion 4, the partitioned air chamber 22 absorbs the impact force through deformation, and the air pressure is dynamically balanced through the connecting pipe 23 and the inflation channel 20 to avoid excessive local pressure.

[0075] Quick exhaust operation

[0076] After the rescue is completed, open the sealing caps 6 of all exhaust pipes 5, start the servo motor 16 to rotate clockwise, and drive the central shaft 13 to retract the airbag cushion 4.

[0077] During the winding process, roller 9 and roller 10 squeeze the airbag pad 4, forcing the gas in the partitioned air chamber 22 to be discharged through the connecting pipe 21 and the exhaust pipe 5.

[0078] The central shaft 13 continues to rotate until the airbag cushion 4 is completely wrapped back into the cavity 8. The connecting belt 19 and the connecting belt 2 18 are wound up simultaneously to avoid the pipeline from getting tangled.

[0079] Close the sealing cap 6 and the sealing plug 15 of the inflation hole 17 to ensure the airbag cushion is sealed in the storage state for easy use next time.
