Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of rescue equipment, and particularly to a foldable rotor-type rescue intelligent flying stretcher. Background Art
[0002] Natural disasters such as earthquakes, debris flows, flash floods, tsunamis, etc., as well as wars, can cause people to die and be injured, and a large number of wounded need to be rescued and treated in a timely manner.
[0003] In the face of emergencies, especially under conditions where land and water transportation is blocked such as snow disasters, earthquakes, and field rescues, relying solely on rescue personnel to carry out on-site rescues often poses certain risks and is prone to delays in rescue. Due to damage and obstruction of transportation roads caused by natural disasters, or communication delays, the time for medical staff to reach the scene for assistance is seriously affected, making the on-site treatment time prone to delay, thus missing the opportunity for treatment. Therefore, a rapid first-aid response can improve the success rate of rescue.
[0004] Currently, the traditional method of transporting the wounded requires medical staff to cross mountains and ridges, which is very difficult, time-consuming, and slow, resulting in untimely rescue.
[0005] In view of this, it is necessary to provide a foldable rotor-type rescue intelligent flying stretcher to overcome the above defects. Summary of the Invention
[0006] The purpose of the present invention is to provide a rescue intelligent flying stretcher that can retract its foldable wings to change its form, which is beneficial for transportation, and can also quickly drive into the disaster scene to transport the wounded to medical sites (such as temporary treatment points, temporary hospitals, etc.) so that the wounded can receive timely treatment and recuperation.
[0007] To achieve the above purpose, the technical solution proposed by the present invention is as follows: A foldable rotor-type rescue intelligent flying stretcher, comprising:
[0008] A stretcher bed, on which support feet are installed, and the stretcher bed is used for loading and transporting the wounded;
[0009] A foldable rotor-type unmanned aerial vehicle, which is connected to the stretcher bed.
[0010] Preferably, a support rod is installed on the stretcher bed, and an infusion bottle can be hung on the support rod.
[0011] Preferably, a hook is installed at the top of the support rod.
[0012] Preferably, a pipe-passing hole is provided on the side wall of the stretcher bed.
[0013] Preferably, the drone includes a fuselage assembly, foldable wings, and rotors. The fuselage assembly is flip-connected to the foldable wings. A motor is disposed inside the foldable wings. The rotors are mounted on the foldable wings and connected to the motor. The motor drives the rotors to rotate, providing power for the foldable rotor drone to fly and lift.
[0014] Preferably, the foldable rotor rescue intelligent flying stretcher further includes a hollow protective cover. The protective cover is mounted on the foldable wings and surrounds the outside of the rotors.
[0015] Preferably, a battery, a communication module, a drone positioning system, and a control module are disposed inside the fuselage assembly. The communication module, the drone positioning system, and the control module are all electrically connected to the battery, and the communication module, the drone positioning system, and the control module are electrically connected. The battery provides electrical energy for the motor, the communication module, the drone positioning system, and the control module.
[0016] Preferably, the head of the foldable wing is provided with an unfolding stop port and a folding stop port. The unfolding stop port and the folding stop port are vertically distributed. A locking connection member is disposed on the fuselage assembly near the head of the foldable wing. The flipping angle of the foldable wing is limited by the cooperation of the locking connection member with the unfolding stop port and the folding stop port.
[0017] Preferably, the locking connection member includes an electromagnetic coil, a latch, and an elastic member. A card slot is disposed on the fuselage assembly near the head of the foldable wing.
[0018] The electromagnetic coil is installed in the card slot and electrically connected to the battery. The latch is inserted into the electromagnetic coil and distributed near the head of the foldable wing. The elastic member is installed in the card slot on the fuselage assembly and connected to the latch.
[0019] Compared with the prior art, the beneficial effects are as follows: 1) The foldable wings can be retracted to change their shape, which is beneficial for transportation. It can also quickly drive into the disaster site and transport the wounded to medical sites (such as temporary treatment points, temporary hospitals, etc.), shortening the waiting time for the wounded to receive treatment, enabling the wounded to receive timely treatment and recuperation. It can be an excellent transportation tool for winning time to rescue lives in disaster relief and emergency rescue. Many problems in transporting the wounded in traditional rescues will be solved easily. It is also an innovation that subverts the traditional rescue method and has a wide market demand in practical applications.
[0020] 2) Installing a protective cover outside the rotors is beneficial for preventing the four rotors from interfering with each other and also avoiding the rotors from coming into contact with relevant personnel and causing accidental injuries.

[0039] Please refer to Figures 1 to 4 , the present invention provides a foldable rotor-type rescue intelligent flying stretcher, comprising:
[0040] A stretcher bed 1, on which support feet 11 are installed, and the stretcher bed 1 is used for loading and transporting the wounded 2;
[0041] A foldable rotor-type unmanned aerial vehicle 3, which is fixedly connected to the stretcher bed 1.
[0042] It should be noted that, in this embodiment, the stretcher bed 1 is made of carbon fiber material, which has excellent mechanical properties, light weight, high strength and hardness, and a plurality of ventilation holes are provided on the stretcher bed 1 so as not to affect the normal breathing of the wounded 2 when the wounded 2 lies flat in the stretcher bed 1 to rest; the stretcher bed 1 adopts a drawer-type design. When the stretcher bed is in the drawn state, the wounded can be placed in the stretcher bed; when the stretcher bed 1 is in the retracted state, the foldable rotor unmanned aerial vehicle 3 starts to fly.
[0043] In this way, when natural disasters damage and block traffic roads, making it impossible for rescue facilities and equipment to drive into the scene, the stretcher bed 1 can load the wounded 2, and the foldable rotor-type unmanned aerial vehicle 3 quickly transports the wounded 2 to the medical site. After the foldable rotor-type unmanned aerial vehicle 3 flies to the destination and lands on the ground, the support feet 11 support on the ground, facilitating the extraction of the stretcher bed 1.
[0044] Please refer to together Figures 5 to 11 , it should be noted that, in this embodiment, the support feet 11 can adopt a two-stage design, and elastic shock-absorbing components (such as springs) can be arranged inside the support feet 11 to enable the support feet 11 to contract appropriately when the stretcher bed 1 bears pressure, so as to increase the earthquake resistance of the stretcher bed 1.
[0045] In a preferred embodiment, a support rod 12 is installed at one end of the stretcher bed 1, and an infusion bottle can be hung on the support rod 12. During transportation, the infusion bottle can be hung on the support rod 12, and the medicinal liquid is transported to the wounded through an infusion tube to timely treat and relieve the pain of the wounded 2.
[0046] In a preferred embodiment, a hook is installed at the top end of the support rod 12, and the infusion bottle is hung by the hook to prevent the infusion bottle from falling.
[0047] In a preferred embodiment, a pipe passing hole 13 is formed in the side wall of the stretcher 1, so that an infusion tube can pass through the pipe passing hole 13 to infuse the wounded 2 lying in the stretcher 1.
[0048] In a preferred embodiment, universal wheels 14 are installed at the bottom of the stretcher 1. After the rescue intelligent flying stretcher transports the wounded 2 to the medical site, the stretcher 1 can be removed and directly pushed away, and the wounded 2 can be transferred to the hospital bed for treatment and rest, without the need to carry the wounded 2 on the back or by lifting, which is very convenient to use.
[0049] It should be noted that, in this embodiment, the number of the universal wheels 14 is four, and the four universal wheels 14 are respectively distributed at the four corners of the stretcher 1 to facilitate maintaining the stability of the stretcher 1.
[0050] In a preferred embodiment, the foldable rotor unmanned aerial vehicle 3 includes a fuselage assembly 31, foldable wings 32 and rotors 33. The fuselage assembly 31 is flip-connected to the foldable wings 32. A motor is arranged inside the foldable wings 32. The rotors 33 are installed on the foldable wings 32 and connected to the motor. The motor drives the rotors 33 to rotate to provide the power for the foldable rotor unmanned aerial vehicle 3 to fly and lift.
[0051] In a preferred embodiment, the foldable rotor rescue intelligent flying stretcher further includes a hollow protective cover 34. The protective cover 34 is installed on the foldable wings 32 and surrounds the outside of the rotors 33, which is beneficial to avoiding interference between the four rotors 33 and also avoiding contact between the rotors 33 and relevant personnel, causing accidental injury. Specifically, the number of the protective covers 34 is two, and the two protective covers 34 are respectively installed on two groups of foldable wings 33.
[0052] In a preferred embodiment, a cross mark is provided on the fuselage assembly 31 to facilitate others to identify that the foldable rotor rescue intelligent flying stretcher is for medical use.
[0053] In a preferred embodiment, a battery 35, a communication module 36, a UAV positioning system 37 and a control module 38 are arranged inside the fuselage assembly 31. The communication module 36, the UAV positioning system 37 and the control module 38 are all electrically connected to the battery 35, and the communication module 36, the UAV positioning system 37 and the control module 38 are electrically connected. The battery 35 provides electrical energy for the motor, the communication module 36, the UAV positioning system 37 and the control module 38.
[0054] In a preferred embodiment, a connecting shaft 311 is provided on the fuselage assembly 31, and the head 321 of the foldable wing 32 is sleeved on the connecting shaft 311 and rotates around the connecting shaft 311 as the center.
[0055] In a preferred embodiment, an unfolding stop opening 322 and a folding stop opening 323 are formed in the head 321 of the foldable wing 32. The unfolding stop opening 322 and the folding stop opening 323 are perpendicularly distributed. A locking connector 39 is provided on the fuselage assembly 31 near the head 321 of the foldable wing 32. By cooperating the locking connector 39 with the unfolding stop opening 322 and the folding stop opening 323, the flipping angle of the foldable wing 32 (the flipping angle is between 0-90°) is limited.
[0056] Specifically, the locking connector 39 includes an electromagnetic coil 391, a pin 392, and an elastic member 393. A slot 312 is provided on the fuselage assembly 31 near the head 321 of the foldable wing 32.
[0057] The electromagnetic coil 391 is installed in the slot 312 and electrically connected to the battery 35. The pin 392 is inserted and installed in the electromagnetic coil 391 and is distributed near the head 321 of the foldable wing 32. The elastic member 393 is installed in the slot 312 on the fuselage assembly 31 and connected to the pin 392.
[0058] It should be noted that in this embodiment, the pin 392 is made of metal (such as iron), and the elastic member 393 is a spring.
[0059] During use, after the electromagnetic coil 391 is controlled by the control module 38 to be energized to generate a magnetic field to adsorb the pin 392 to move into the slot 312 of the fuselage assembly 31, the foldable wing 32 is manually unfolded so that the unfolding stop opening 322 is aligned flush with the pin 392. After the electromagnetic coil 391 is controlled by the control module 38 to be de-energized and the magnetic field disappears, under the elastic force of the elastic member 393, the pin 392 extends out of the slot 312 of the fuselage assembly 31 into the unfolding stop opening 322 to limit the foldable wing 32 and keep the foldable wing 32 in a horizontally unfolded state.
[0060] When not in use, after the electromagnetic coil 391 is controlled by the control module 38 to be energized again to generate a magnetic field to adsorb the pin 392 to move into the slot 312 of the fuselage assembly 31, the foldable wing 32 is manually folded so that the folding stop opening 323 is aligned flush with the pin 392. After the electromagnetic coil 391 is controlled by the control module 38 to be de-energized and the magnetic field disappears, under the elastic force of the elastic member 393, the pin 392 extends out of the slot 312 of the fuselage assembly 31 into the folding stop opening 323 to limit the foldable wing 32 and keep the foldable wing 32 in a folded state (the foldable wing 32 is perpendicular to the fuselage assembly 31).
[0061] It should be noted that in this embodiment, the number of the foldable wings 32 is four. The four foldable wings 32 are divided into two groups, and the two groups of foldable wings 32 are respectively distributed on both sides of the fuselage assembly 31. The motor is a brushless motor, and the number of the rotors 33 is four. The four rotors 33 are respectively installed at one ends of the four foldable wings 32 away from the fuselage assembly 31.
[0062] It should also be noted that the rotor 33 can adopt a coaxial dual-rotor design, that is, the rotor 33 with a double-layer symmetrical layout generates lift through two coaxially rotating rotors 33 in opposite directions. In this way, the foldable rotor UAV 3 can carry a greater weight during flight.
[0063] It should be noted that in this embodiment, the communication module 36 communicates with the UAV gateway by using protocols such as RTMP, the national standard method of GB / T28181, and HDMI. After the foldable rotor UAV 3 communicates with the UAV gateway, it can transmit images and videos back to the UAV flight control handle and the command center in real time.
[0064] The UAV positioning system 37 has two positioning modes:
[0065] Mode 1: Satellite positioning mode (GPS, Beidou positioning). In the satellite positioning mode, when operating the UAV flight control handle, the foldable rotor UAV 3 can fly automatically and intelligently and return automatically.
[0066] Mode 2: Vision positioning system (positioning through the vision sensor carried on the aircraft). When the GPS signal is insufficient, but the light is sufficient and the ground texture is clear, the foldable rotor UAV 3 automatically enters the vision positioning mode (the foldable rotor UAV 3 can be equipped with an LED fill light, which can be automatically lit in case of insufficient light to illuminate the ground and assist the vision system for positioning).
[0067] In the technical solution of this patent, the maximum flight speed of the foldable rotor UAV 3 is 40 km / h, the endurance is 30 min, and the flight altitude is less than 3 km.
[0068] The present invention is not limited only to what is described in the specification and the embodiments. Therefore, for those skilled in the art, additional advantages and modifications can be easily achieved. Thus, without departing from the spirit and scope of the general concept defined by the claims and the equivalent scope, the present invention is not limited to the specific details, representative devices, and the illustrated examples shown and described here.
