Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0042] It should be noted that similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0043] Embodiment

[0044] As Figures 1 - 3 shown, the present invention provides a single-person escape device suitable for high-rise building fires, including a fuselage 1. A battery 2 is arranged inside the fuselage 1, and protective plates 3 are symmetrically arranged on both sides of the fuselage 1. A front searchlight 4 is arranged at the top of the fuselage 1, a tail fin 5 is arranged at the bottom of the fuselage 1, and a rear searchlight 6 is arranged at the bottom end of the tail fin 5. A rescue sign 7 is arranged on one side of the fuselage 1, and a drive button is also arranged on the fuselage. A strain type gravity sensor is arranged inside the fuselage. A strain unit is arranged on the strain type gravity sensor. The strain unit is a material that will produce a small deformation under the action of force, thereby causing a change in the resistance value. When gravity acts on the strain type gravity sensor, the strain unit will deform, resulting in a change in the resistance value. This change in the resistance value can be measured and converted through a connected bridge circuit or other signal processing circuits, and finally an electrical signal related to the magnitude of the force is output.

[0045] Two groups of symmetric wing rods 8 are arranged on the fuselage 1. The wing rods 8 include a wing rod one 81 and a wing rod two 82. Connecting rods 9 are hinged to the other ends of the wing rods 8. Connection blocks 10 are fixedly installed at the other ends of the connecting rods 9. Motors 11 are fixedly arranged at the tops of the connection blocks 10. Output ends of the motors 11 are connected with propellers 12. Wheel protection shells 13 are sleeved outside the propellers 12. The wing rods 8 and the propellers 12 are in an X-shaped structure.

[0046] A backrest pad 14 is arranged on one side of the fuselage 1. A protective headgear 15 and a hand-held induction handle 16 are arranged at the top of the backrest pad 14. The hand-held induction handle 16 is arranged on both sides of the protective headgear 15. A five-point seat belt 17 is connected to the backrest pad 14.

[0047] The five-point seat belt 17 includes a shoulder strap 171, a waist belt 172, leg straps 173 and a buckle 174. The shoulder straps 171 are symmetrically arranged on the back pad 14, and the other ends of the shoulder straps 171 are both connected to the buckle 174. One end of the waist belt 172 is symmetrically arranged on the tail fin 5, and the other ends of the waist belt 172 are both connected to the buckle 174. The leg straps 173 are symmetrically arranged on the tail fin 5, and locks are provided at the other ends of the leg straps 173. A lock hole is provided on the buckle 174, and the lock and the lock hole are snap-connected. An induction chip is provided on the shoulder strap 171 to detect and confirm whether the seat belt is worn in accordance with the flight standard.

[0048] The buckle is an induction adjustable buckle, and the tightness of the belt can be automatically sensed and adjusted through the induction adjustable buckle.

[0049] The load and stress analysis of the single-person escape device is as follows:

[0050] 1. Total load-bearing mass of the device

[0051] During the actual escape process, the escapee leaves through the escape exit. The total mass M can be divided into two parts: the human body mass M1 and the device mass M2 (ignoring gas leakage). Therefore, the total mass during the escape process is:

[0052] M = M1 + M2;

[0053] Taking into account the applicable range of the device, the human body mass M1 is set at a level close to the upper limit P99 and the lower limit P1, that is, M1 = 35 - 100 kg is selected. At the same time, in order to ensure the portability and practicality of the device, the mass M2 of the device is limited within 20 kg, specifically set as M2 = 20 kg. In order to meet the safety requirements, a 20% additional load-bearing margin is reserved to improve the safety performance of the device. That is to say, it is necessary to ensure that the total mass that the device can safely carry is increased by 20%, that is, the safety factor η = 1.2 is taken.

[0054] Therefore, the total mass M that the single-person escape device needs to be able to carry 总 should be:

[0055] M total = ηM;

[0056] Substituting the data into the above formula, it can be obtained that the total mass that the device can carry is 120 kg.

[0057] Therefore, the applicable population range of this device is within a body weight of 35 - 100 kg, and at the same time, it needs to meet the vast majority of people with a height of 120 cm - 200 cm and an age of over 7 years old.

[0058] 2. Lift force analysis of the propeller

[0059] This device is equipped with four propellers and is a rigid body with uniform symmetry, capable of being unaffected by other factors such as resistance, air pressure, and materials. Refer to Figure 4 , the four propellers and the wing rods form an X shape. Label the four propellers as 01, 02, 03, and 04 respectively. When the device is rotating stably, the rotation directions of 01 and 02 are the same, and the rotation directions of 03 and 04 are the same. The power of this device comes from the high-speed rotation of the propellers. During the rotation of the propellers, due to the relationship between the angle of attack and the air action, the air flow will generate a thrust perpendicular to the plane of the propeller on the propeller. This thrust can be decomposed into a force Tt perpendicular to the plane of the fuselage and a force Tm parallel to the plane of the fuselage. Refer to Figure 5 , where Tt is the lifting force for the escape device to rise, and Tm is the force that causes the escape device to rotate and translate.

[0060] Based on the assumption that this escape device is only affected by gravity and the pulling force of the propellers, when the four propellers are parallel to the plane of the fuselage and rotate at the same speed, the air thrust received by the propellers is perpendicular to the plane of the fuselage, and there is no horizontal force parallel to the fuselage. Therefore, the entire escape device will not rotate or move horizontally. Although the rotation directions of the four propellers are different, the directions of the forces received are all vertically upward perpendicular to the plane of the fuselage. Refer to Figure 6 , the lifting force effect received by the escape device is the vertical resultant force T of the sum of four identical lifting forces acting on the center of the fuselage plane. At the same time, the overall gravity G of the escape device also acts on the center of the fuselage plane.

[0061] The magnitude of the lifting force generated by a single propeller is related to the rotational speed and can be expressed as:

[0062]

[0063] Among them, T i is the lifting force generated by a single propeller, C t is the pulling force coefficient, is the rotational speed of the propellers of the escape device. The overall lifting force is 4 times that of a single lifting force. At this time, the motion state of the escape device is determined by the magnitudes of the total lifting force and gravity. When the lifting force is greater than gravity, the escape device accelerates vertically upward; when the lifting force is equal to gravity, the escape device hovers or moves at a constant speed; when the lifting force is less than gravity, the escape device accelerates vertically downward.

[0064] The escape device can not only perform vertical translation but also has the capabilities of pitching, rolling, forward and lateral movement. When performing these movements, it is necessary to adjust the rotational speeds of the propellers with the same rotation direction so that the rotational speeds of the same propellers are different.

[0065] Refer to Figure 7, when keeping the directions and magnitudes of the No. 02 and No. 04 propellers unchanged and adjusting the rotational speeds of the No. 01 and No. 03 propellers (but keeping the rotational directions unchanged), the lift forces generated by the two propellers are made different. This will generate a moment in the x-axis plane, causing the escape device to pitch around the y-axis, and the specific pitching direction depends on which propeller generates a greater lift force. If the lift force of the No. 01 propeller (the upward arrow represents an increase in rotational speed) is greater than that of the No. 03 propeller, a downward pitching motion will occur. When the escape device starts to rotate, the thrust given by the air to the propeller is perpendicular to the rotational plane of the propeller. The component of this perpendicular thrust provides the lift force, while the horizontal component will generate a force on the escape device in the front-back direction. Therefore, the front-back motion of the escape device also depends on which propeller generates a greater lift force - if the lift force of the front propeller is greater, a backward motion will occur, and vice versa, referring to Figure 8 , the escape device shows a backward motion. The same mechanical principle applies when keeping the directions and magnitudes of the No. 01 and No. 03 propellers unchanged and adjusting the rotational speeds of the No. 02 and No. 04 propellers (without changing the rotational directions) to make the lift forces generated by the two propellers different, which will cause the escape device to roll and move laterally, as shown in Figures 9 - 10 .

[0066] During the above motion process, the rotation satisfies the following dynamic equations:

[0067]

[0068] where C mx , C my are torque coefficients, which are constants related to experiments and experience.

[0069] Finally, when the rotational speeds of the four propellers are inconsistent, to satisfy the conservation of angular momentum, the escape device will have a rotation around the z-axis, and its dynamic equation is:

[0070]

[0071] where C mz is also a torque coefficient.

[0072] Summarize the dynamic formula into matrix form:

[0073]

[0074] where T represents the total lift force, and T mx , T my , T mz represent the lift forces in the x, y, and z directions respectively.

[0075] By substituting the initial conditions and relevant parameters and solving the equations, all the state information of the escape device during flight can be obtained.

[0076] The single-person escape device is also equipped with a mobile phone APP. Users can directly initiate a one-key emergency call for help - emergency activation through "My" in the APP to improve the efficiency of escape and rescue. The specific content is as follows:

[0077] Users can obtain information related to fire self-rescue and equipment usage through the mobile phone APP; in case of an emergency, users can quickly and effectively wear the escape equipment with the help of the voice operation guidance in the mobile phone APP, thereby increasing the probability of escape; in addition, users can make an appointment for offline training on the use of escape equipment and conduct regular safety performance inspections of the equipment. Refer to Figure 11 , the main interface of the mobile phone APP mainly includes: authentication and login, fire knowledge, equipment usage, usage guidelines, personal center, and emergency contact, etc. In addition, for the convenience of users, the product also provides special features such as usage guidelines during a disaster and voice comfort, which can meet the needs of users, provide comprehensive functional support, ensure that users can act quickly and effectively in case of a fire emergency, and ensure the safety performance of the equipment through training and regular inspections.

[0078] The information architecture of the mobile phone APP is based on the extension of its functions and these functions are detailedly split. Through the comprehensive analysis of the mobile phone APP interface, the following interface information architecture covering the single-person escape device and the mobile phone APP is sorted out. Refer to Figure 12 .

[0079] Refer to Figure 13 , the present invention also provides a method for using a single-person escape device suitable for high-rise building fires, including the following steps:

[0080] Before a fire accident occurs:

[0081] Preset the preparation stage of the single-person escape device. For example, check the power supply and ensure that the sensor is operating normally.

[0082] Add emergency notification methods through the APP, including text messages, phone calls, and APP reminders, to ensure timely notification of relevant personnel in case of a fire.

[0083] Users can preview and set the escape route in advance, including setting escape channels and safe havens, to ensure that they can quickly escape according to the pre-planned route in case of a fire.

[0084] Users can set emergency contact information in advance so as to quickly contact relevant personnel for support during the escape process.

[0085] Users can also preset monitoring requirements for physiological parameters, such as heart rate and respiration, etc., so as to obtain relevant physiological information in a timely manner in case of emergency. These preset operation procedures help improve the flexibility and applicability of the product, ensuring that users can respond to various situations more efficiently and safely during the fire escape process.

[0086] When a fire accident occurs:

[0087] The user needs to take out the single-person escape device and place it flat on the ground.

[0088] According to the wearing method guide, the user needs to quickly wear the single-person escape device, and the device will automatically detect and confirm whether the wearing meets the flight standards. The wearing method is a foolproof wearing method, which includes the following steps: Wear the device like carrying a backpack; Pass the leg straps through both legs, wrap around the thighs and snap into the lock holes of the buckles; The device will automatically sense and adjust the tightness of the straps to ensure safe wearing and provide a comfortable experience.

[0089] When the user is ready to jump through the window to the escapable route, the single-person escape device will automatically start within 0.1 second through gravity sensing technology (i.e., strain gauge sensors) and quickly enter the flight state. This fast and intelligent response mechanism allows users to immediately escape from the dangerous area when escaping from a high altitude in a fire.

[0090] The GPS built into the single-person escape device will automatically search for and execute the preset escape route, find the nearest safe landing point, ensure the user lands safely and wait for rescue.

[0091] Therefore, the present invention adopts the above-mentioned method for using a single-person escape device suitable for high-rise building fires, solves the limitations of traditional escape means, and ensures that ordinary users can also use it quickly and escape safely.

[0092] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that they can still modify or equivalently replace the technical solutions of the present invention, and these modifications or equivalent replacements cannot make the modified technical solutions deviate from the spirit and scope of the technical solutions of the present invention.
