Description

Technical Field

[0001] This application relates to the field of escape devices, specifically to an emergency rescue device. Background Technology

[0002] With the increasing number of high-rise buildings, the issue of emergency escape in high-rise buildings has become increasingly prominent. When a fire occurs in a high-rise building, hot smoke and toxic gases spread rapidly along vertical passages such as stairwells and elevator shafts, making evacuation staircases difficult to navigate. Furthermore, in the event of an emergency, elevators may malfunction and trap people inside, rendering them unusable during a disaster; and ladder trucks are limited by height, making it difficult to effectively rescue people from extremely high floors. This poses a significant obstacle to the escape of high-rise residents during a disaster. Currently, most high-rise residents still rely on traditional evacuation staircases and simple escape tools, methods that are inefficient and unsafe, clearly failing to effectively guarantee the safety of high-rise residents. Utility Model Content

[0003] This application addresses the aforementioned shortcomings of the prior art by providing an emergency rescue device to solve at least one of the aforementioned technical problems, as detailed below:

[0004] An emergency rescue device includes a parachute and a cushioning base. The parachute is connected to the cushioning base; the cushioning base is provided with a connecting component for connecting a rescue target; the parachute has an opening for the rescue target to pass through the parachute and contact the cushioning base.

[0005] In some specific embodiments, a first connector is also included, with one end of the first connector connected to the umbrella body and the other end connected to the buffer base.

[0006] In some specific embodiments, a second connector is also included. Multiple first connectors are included, and the two ends of the second connector are respectively disposed on adjacent first connectors. In one specific embodiment, the two ends of the second connector are respectively disposed on adjacent first connectors at a predetermined distance from the umbrella body; this is used to strengthen the connection structure between adjacent first connectors. In one specific embodiment, the predetermined distance is not less than half the total length of the first connector.

[0007] In some specific embodiments, the first connector and / or the second connector includes an airbag structure. By setting the first connector and / or the second connector as an airbag structure, when the airbag structure is inflated, it can provide more stable support for the parachute, allowing the parachute to fully unfold and maintain its shape. It can also increase the buoyancy of the emergency device as a whole during descent and reduce the air resistance experienced by the parachute, thereby reducing the descent speed of the emergency device and ensuring that the rescue target lands smoothly and safely.

[0008] During the landing and contact with the ground, if the first and / or second connecting parts collide or rub against other external facilities, their airbag structure can better absorb and disperse the impact force, improving the overall cushioning and shock absorption performance. When the rescue target is a person or animal, setting the first and / or second connecting parts as an airbag structure can reduce the turbulence and discomfort caused during the descent and help the rescue device achieve a stable descent from high altitude.

[0009] When the rescue target is located on the buffer base, the first and / or second connectors connecting the buffer base can also block and buffer any impacts or debris that may come from other directions outside the buffer base, thus achieving all-round protection for the rescue target.

[0010] In some specific embodiments, the airbag structure includes multiple inflatable bladders, which can be interconnected or independent of each other. Each independent inflatable bladder is connected to at least one gas generator. In one specific embodiment, adjacent inflatable bladders can be connected through a one-way valve to form at least one one-way inflation channel. In practical applications, by connecting adjacent inflatable bladders through one-way valves, if one inflatable bladder of the airbag structure is scratched or damaged during rescue operations, it will not affect the adjacent inflatable bladders, thus further ensuring the safety of the rescue target.

[0011] In some specific embodiments, at least one gas generator is connected to the airbag structure. In practical applications, the user can trigger the gas generator directly by hand or remotely. Once triggered, the gas generator can quickly inflate the airbag structure.

[0012] In some specific embodiments, the umbrella body includes an umbrella connecting piece and umbrella units; one end of the umbrella connecting piece is disposed at the connection between two adjacent umbrella units, and the other end is connected to a first connector and / or a buffer base, thereby forming multiple buffer spaces within the umbrella body to provide cushioning. In practical applications, the buffer spaces formed within the umbrella body are semi-open air chambers. During descent, the buffer spaces can intercept more airflow, providing greater resistance to the descent of the umbrella body and further reducing the descent speed of the umbrella body and the buffer base.

[0013] In some specific embodiments, an inflatable support is also included, which is disposed along part or all of the edge of the buffer base to improve the structural strength of the buffer base.

[0014] In some specific embodiments, the buffer base includes a cylindrical structure, a frustum structure, or a pyramidal structure; at least one vent is provided on the bottom and / or side of the buffer base. In practical applications, by setting a cylindrical or frustum structure, the rescue target can be better supported and cushioned.

[0015] In one specific embodiment, the inflatable support includes an upper support provided along part or all of the edges of the top surface of the buffer base, and / or a lower support provided along part or all of the edges of the bottom surface of the buffer base, and / or a side support provided on the side of the buffer base; wherein, one end of the side support faces the top surface of the buffer base, and the other end faces the bottom surface of the buffer base.

[0016] The two ends of the side support can be connected to the upper support and the lower support, respectively. In one specific embodiment, an upper support is arranged around the top surface of the buffer base, a lower support is arranged around the bottom surface of the buffer base, and side supports are arranged on the sides of the buffer base, connecting the upper and lower support. When the buffer base descends and contacts the ground, the lower support of the buffer base contacts the ground first and receives an upward impact from the ground, while the side supports can bear and absorb this impact force, keeping the buffer base as a whole from deforming.

[0017] In practical applications, the first connector, the second connector, and the inflatable support are interconnected, and the entire emergency rescue device can be inflated and formed by at least one gas generator.

[0018] In a specific application, after the user triggers the gas generator, the gas generator can quickly inflate the first connector, the second connector, and the inflatable support. After being inflated, the first and second connectors can open the umbrella body and provide strong support for the umbrella body. The inflatable support serves as the support frame of the buffer base. After being inflated, it can support the buffer base and unfold the buffer base to form a cylindrical structure, a frustum structure, or a pyramidal structure from a contracted state.

[0019] In some applications, the three components can be interconnected or independent. Depending on the user's needs, one or more of the upper support, lower support, and side support components may also be connected to a gas generator. In one specific embodiment, the upper support component is thicker, specifically, it may be thicker than the lower support component, providing stronger support. Together with the buffer base on the side facing the umbrella, it forms an elastic support structure with higher elasticity, enabling better containment of the rescue target.

[0020] In some specific embodiments, guide nozzles are provided on some or all of the vents. In one specific embodiment, the diameter of the guide nozzles provided on the vents located at the bottom of the buffer base decreases from the side where the guide nozzles are located towards the inside of the buffer base.

[0021] In one specific embodiment, a guide nozzle is provided on the side of the buffer base away from the umbrella body, and an air outlet is provided on the side of the buffer base facing the umbrella body, corresponding to the vent on the side away from the umbrella body. This allows airflow to enter the buffer base from the vent through the guide nozzle during rapid descent from a height, and then exit through the air outlet. This rectifyes the airflow entering the buffer base, allowing it to flow smoothly within the buffer base along a pre-set path, stabilizing the airflow velocity, and reducing the possibility of the buffer base swaying or overturning due to uneven air pressure. This makes the buffer base more stable during descent, with less attitude change, and can better ensure the safety of the rescue target.

[0022] In one specific embodiment, the buffer base is provided with at least one internal buffer support for providing cushioning. The internal buffer support can be positioned from the side of the buffer base closest to the umbrella body towards the side of the buffer base furthest from the umbrella body. By providing the internal buffer support, when the buffer base contacts the ground, the inflatable support at the edge of the buffer base can absorb the impact force on the edge of the buffer base, while the internal buffer support inside the buffer base can absorb the impact force of the ground on the entire bottom of the buffer base, thus providing cushioning for the rescue target.

[0023] Beneficial Effects: This application provides an emergency rescue device, including a parachute and a buffer base. The parachute is connected to the buffer base; the buffer base is provided with a connecting component for connecting a rescue target; by providing an opening in the parachute for the rescue target to pass through the parachute and contact the buffer base, the rescue target can accurately land on the buffer base through the opening during a fall from a height. The buffer base can effectively wrap and cushion the rescue target, and the parachute can effectively reduce the descent speed of the buffer base, thereby achieving emergency rescue of the rescue target while ensuring high safety during the rescue process. It has a wide range of applications, a simple structure, fast opening speed, and high rescue efficiency. Attached Figure Description

[0041] Example

[0042] This application provides an emergency rescue device that can provide rapid and comprehensive protection and cushioning for rescue targets falling from heights. The specific solution is as follows:

[0043] An emergency rescue device includes an umbrella body 1 and a buffer base 2. The umbrella body 1 is connected to the buffer base 2; the buffer base 2 is provided with a connecting component 21 for connecting a rescue target; the umbrella body 1 is provided with an opening 11, which allows the rescue target to pass through the umbrella body 1 to contact the buffer base 2, such as... Figure 1 and Figure 3 As shown.

[0044] In some specific embodiments, a first connector 3 is also included, one end of which is connected to the umbrella body 1 and the other end is connected to the buffer base 2.

[0045] In some specific embodiments, a second connecting member 4 is also included. Multiple first connecting members 3 are included, and the two ends of the second connecting member 4 are respectively disposed on adjacent first connecting members 3. In one specific embodiment, the two ends of the second connecting member 4 are respectively disposed on adjacent first connecting members 3 at a predetermined distance from the umbrella body 1; this is used to strengthen the connection structure between adjacent first connecting members 3. In one specific embodiment, the predetermined distance is not less than half the total length of the first connecting member 3. In one specific embodiment, the second connecting member 4 forms a ring-shaped connecting structure on the first connecting member, which can strengthen the overall structural strength of the first connecting member 3 and prevent the first connecting member 3 from deforming during a fall from a height.

[0046] In some specific embodiments, the first connector 3 and / or the second connector 4 include an airbag structure.

[0047] By setting the first connector 3 and / or the second connector 4 as an airbag structure, when the airbag structure is inflated, it can provide more stable support for the umbrella body 1, allowing the umbrella body 1 to fully unfold and take shape, and can maintain the umbrella body 1 without deformation. At the same time, it can also increase the buoyancy of the emergency device as a whole during the descent process and the air resistance experienced by the umbrella body 1, reduce the descent speed of the emergency device, and enable the rescue target to land smoothly and safely.

[0048] During the landing and contact with the ground, if the first connecting member 3 and / or the second connecting member 4 collide or rub against other external facilities, their airbag structure can better absorb and disperse the impact force, improving the overall cushioning and shock absorption performance. When the rescue target is a person or animal, setting the first connecting member 3 and / or the second connecting member 4 as an airbag structure can reduce the turbulence and discomfort caused during the descent and help the rescue device achieve a stable descent from high altitude.

[0049] When the rescue target is located on the buffer base 2, the first connector 3 and / or the second connector 4 connecting the buffer base 2 can also block and buffer the impact or debris that may come from other directions outside the buffer base 2, thus achieving all-round protection for the rescue target.

[0050] In some specific embodiments, the airbag structure includes multiple airbags, which can be interconnected or independent of each other. Each independent airbag is connected to at least one gas generator 6. In one specific embodiment, adjacent airbags can be connected by a one-way valve, so that if one of the airbags is scratched or damaged during the rescue, it will not affect the other adjacent airbags, thus further ensuring the safety of the rescue target.

[0051] In some specific embodiments, at least one gas generator 6 is connected to the airbag structure. In practical applications, the user can trigger the gas generator 6 directly by manual triggering or remote control. Once triggered, the gas generator 6 can quickly inflate the airbag structure.

[0052] In some specific embodiments, the umbrella body 1 includes an umbrella connecting piece 12 and an umbrella unit 13;

[0053] One end of the umbrella connecting piece 12 is located at the connection point of two adjacent umbrella units 13, and the other end is connected to the first connecting piece 3 and / or the buffer base 2, so as to form multiple buffer spaces within the umbrella body 1 for providing cushioning. In practical applications, the buffer space formed within the umbrella body 1 is a semi-open air chamber. During descent, the buffer space can intercept more airflow, providing greater resistance to the descent of the umbrella body 1 and further reducing the descent speed of the umbrella body 1 and the buffer base 2.

[0054] In some specific embodiments, an inflatable support 5 is also included, which is disposed along part or all of the edge of the buffer base 2 to improve the structural strength of the buffer base 2.

[0055] In one specific embodiment, the first connector 3 includes a straight tube airbag, one end of which is connected to the umbrella body 1 and the other end is connected to the buffer base 2 or to the inflatable support 5 provided on the buffer base 2.

[0056] In one specific embodiment, the connecting component 21 includes a safety belt, through which the rescue target is connected to the buffer base 2. During the descent of the emergency rescue device from a height, the safety belt ensures the connection between the rescue target and the buffer base 2, allowing the target to land smoothly within the buffer base 2 and be protected by it.

[0057] In a specific rescue operation, the connecting component 21 is equipped with a quick-release structure. The rescue target and the buffer base 2 can be connected using the connecting component 21 first, and then the connecting component 21 can be detachably connected to the external fixing device. This ensures that the tension generated by the buffer base 2 during inflation will not pull the rescue target outward prematurely. After the umbrella body 1 and the buffer base 2 are fully opened, the connection between the connecting component 21 and the external fixing device can be disconnected through the quick-release structure. At this point, the rescue target can be dropped from a height, and the umbrella body 1 and the buffer base 2 can effectively protect and rescue the rescue target.

[0058] In some specific embodiments, the buffer base 2 includes a cylindrical structure, a frustum structure, or a pyramidal structure; at least one vent 24 is provided on the bottom and / or side of the buffer base 2, such as... Figure 4 As shown. In practical applications, by setting up a cylindrical or frustum structure, the rescue target can be better supported and cushioned.

[0059] In one specific embodiment, the inflatable support 5 includes an upper support 51 disposed along part or all of the edges of the top surface of the buffer base 2, and / or a lower support 52 disposed along part or all of the edges of the bottom surface of the buffer base 2, and / or a side support 53 disposed on the side surface of the buffer base 2; wherein, one end of the side support 53 faces the top surface of the buffer base 2, and the other end faces the bottom surface of the buffer base 2.

[0060] The two ends of the side support 53 can be connected to the upper support 51 and the lower support 52, respectively. In one specific embodiment, the upper support 51 is arranged around the top surface of the buffer base 2, the lower support 52 is arranged around the bottom surface of the buffer base 2, and the side support 53, which connects the upper support 51 and the lower support 52, is provided on the side of the buffer base 2. When the buffer base 2 descends and contacts the ground, the lower support 52 of the buffer base 2 contacts the ground first and is subjected to an upward impact from the ground, while the side support 53 can bear and absorb this impact force, keeping the buffer base 2 as a whole from deforming.

[0061] In practical applications, the first connector 3, the second connector 4, and the inflatable support 5 are interconnected, and the entire emergency rescue device can be inflated and formed by at least one gas generator 6.

[0062] In a specific application, after the user triggers the gas generator 6, the gas generator 6 can quickly inflate the first connector 3, the second connector 4, and the inflatable support 5. After the first connector 3 and the second connector 4 are inflated and formed, they can open the umbrella body 1 and provide strong support for the umbrella body 1. The inflatable support 5 serves as the supporting frame of the buffer base 2. After inflation, it can support the buffer base 2, unfold the buffer base 2, and form it from a contracted state into a cylindrical structure, a frustum structure, or a pyramidal structure.

[0063] In some applications, the three components can be interconnected or independent. Depending on the user's needs, one or more of the upper support 51, lower support 52, and side support 53 may also be connected to the gas generator 6. In one specific embodiment, such as... Figure 7 As shown, the upper support member 51 has a larger thickness, specifically, it can be thicker than the lower support member 52, thus having stronger support force. Together with the buffer base 2 on the side facing the umbrella body 1, it forms an elastic support structure with higher elasticity, which can better wrap the rescue target.

[0064] In one specific embodiment, the buffer base 2 includes a buffer pad 22 and a connecting ring 7 on the side facing the umbrella body 1. The edge of the buffer pad 22 is connected to the edge of the buffer base 2 facing the umbrella body 1 via the connecting ring 7. In practical applications, the buffer pad 22 is tightened relative to the edge of the buffer base 2, which makes the overall structure of the buffer base 2 more stable and reduces the shaking and displacement of the buffer base 2 during use. In the tightened state, the buffer pad 22 can more evenly bear the impact force generated when the rescue target falls onto the buffer pad 22, avoiding excessive local stress that could cause the buffer pad 22 to tear.

[0065] In some specific embodiments, such as Figure 2 and Figure 5 As shown, some or all of the vents 24 are equipped with guide nozzles 25. In one specific embodiment, the guide nozzles 25 located on the vents 24 at the bottom of the buffer base 2 have diameters that decrease from the side where the guide nozzles 25 are located towards the inside of the buffer base 2. Specifically, the guide nozzles 25 are soft structures. When airflow enters the vents 24, the guide nozzles 25 open in the direction of the airflow to guide the gas. This allows the airflow to enter the buffer base 2 from the vents 24 through the guide nozzles 25 during the rapid descent of the buffer base 2 from a height, and then exit from the buffer base 2 through the outlet 26. This rectifyes the airflow entering the buffer base 2, allowing it to flow smoothly within the buffer base 2 along a pre-set path, stabilizing the airflow velocity, and reducing the possibility of the buffer base 2 swaying and overturning due to uneven air pressure. This makes the buffer base 2 more stable during descent, with less change in posture, and can better ensure the safety of the rescue target.

[0066] In one specific embodiment, such as Figure 6 As shown, the buffer base 2 is provided with at least one internal buffer support 23 for providing cushioning. The internal buffer support 23 can be arranged from the side of the buffer base 2 closest to the umbrella body 1 toward the side of the buffer base 2 furthest from the umbrella body 1. By providing the internal buffer support 23, when the buffer base 2 contacts the ground, the inflatable support 5 provided at the edge of the buffer base 2 can absorb the impact force on the edge of the buffer base 2, while the internal buffer support 23 inside the buffer base 2 can absorb the impact force of the ground on the bottom of the buffer base 2 as a whole, providing cushioning for the rescue target.

[0067] This embodiment provides an emergency rescue device, including a canopy and a buffer base. The canopy is connected to the buffer base; the buffer base is provided with a connecting component for connecting a rescue target; by providing an opening in the canopy, the rescue target is allowed to pass through the canopy to contact the buffer base, so that the rescue target can accurately land on the buffer base through the opening during a fall from a height. The buffer base effectively wraps and cushions the rescue target to achieve emergency rescue. Its structure is simple, opens quickly, and has high rescue efficiency. By incorporating a flow guide nozzle and internal buffer supports within the buffer base, the buffering and protective capabilities of the emergency rescue device can be further improved.

[0068] The above is a detailed description of the preferred embodiments of this application. However, the invention of this application is not limited to the embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of this application. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
