Description

Technical Field

[0001] This utility model relates to the field of drone rescue technology, and in particular to a box-type drone capable of high-altitude and high-rise building rescue. Background Technology

[0002] With the acceleration of urbanization, high-rise building fires, earthquakes, and other disasters are becoming more frequent, leading to an increasing number of people being trapped in high-rise buildings. Traditional rescue methods are limited by unfavorable factors such as complex terrain, strong winds, smoke, and signal interference, resulting in slow response times and low efficiency. Among the new rescue methods, drones can be used for airdrop or transport to deliver emergency relief supplies, such as first aid kits, oxygen cylinders, and protective clothing, to trapped individuals. This requires drones to have high-altitude flight capabilities as well as the ability to navigate between stairwells where fires occur. When in high-temperature environments, the outer rotors of drones often become damaged after a few flights and transports. Detailed repairs would waste rescue time, therefore, rapid replacement of drone rotors is necessary. Utility Model Content

[0003] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of this invention may be realized and obtained by means of the structures particularly pointed out in the description and other accompanying drawings.

[0004] The purpose of this utility model is to overcome the above-mentioned shortcomings and provide a box-type drone for high-altitude and high-rise building rescue. By setting up a drone with a cargo box, the drone has a cargo carrying function and can transport emergency rescue supplies, such as first aid kits, oxygen cylinders, and protective clothing, to higher floors. At the same time, the drone has a driving function and can travel between corridors to accurately deliver supplies to trapped personnel. During use, due to the high temperature environment of a fire, the outer drone rotor often becomes damaged after a few flights and transports. Therefore, a quick-removable and replaceable lifting rotor is set up. By quickly inserting a limiting plate into an elastic fixing device to fix the position and tightening the connection with fixing screws, the lifting rotor is tightly connected and easy to replace.

[0005] This utility model provides a box-type drone for high-altitude and high-rise building rescue, including a cargo box with an internal cavity, detachable lifting rotors located at the four corners of the cavity and extending outward from the cargo box, an electric four-wheel drive chassis located on the bottom side of the cargo box, and a control center located within the cavity. The control center is electrically connected to the lifting rotors and the electric four-wheel drive chassis. The cavity is divided into an upper and lower layer by a partition. The control center is located in the lower layer, and the lifting rotors are located in the upper layer. The lifting rotors include rotor arms, limiting plates, and fixing screws. Elastic fixing devices are provided at each of the four corners of the cavity, and the elastic fixing devices are located in the upper layer. The lifting rotors are fixed to the cavity by the elastic fixing devices.

[0006] The upper layer of the cargo container is used to store emergency rescue supplies, such as first aid kits, oxygen cylinders, and protective clothing. The lower layer is the central hub for controlling the entire drone operation. To prevent high temperatures from intruding into the control center, a partition is installed to separate the two functional areas, providing protection. The lifting rotor is used for high-altitude flight, and the electric four-wheel drive chassis allows the cargo container to move between stairwells in high-rise buildings, enabling precise delivery of supplies to trapped personnel. Furthermore, due to the high-temperature environment, the outer drone rotor often suffers damage after several flights and transports. Therefore, the lifting rotor allows for quick disassembly and replacement, saving rescue time. Preferably, the cargo container is made of lightweight material and coated with a high-temperature resistant layer to protect the rescue supplies. The top cover of the cargo container should be easy to open without any locking mechanisms, allowing trapped personnel to quickly access the contents. The specific structures of the rotor arms and the electric four-wheel drive chassis can refer to existing technologies.

[0007] In some embodiments, a limiting plate is provided at one end of the rotor arm, the limiting plate extends downward and is engaged in the elastic fixing device, and the other end of the rotor arm extends outside the cargo box. The fixing screw is rotatably connected to the limiting plate. The limiting plate extends downward into the receiving cavity and cooperates with the elastic fixing device to fix the current position of the lifting rotor. At the same time, in order to make the connection between the lifting rotor and the box more tight, a fixing screw is provided to connect with the partition, so that the lifting rotor can drive the cargo box to fly.

[0008] In some embodiments, the elastic fixing device includes a first elastic component, a second elastic component, and a positioning plate. The first and second elastic components are respectively disposed on the two side walls of the cargo box, and the positioning plate is disposed on the partition plate, forming a triangular structure between the two side walls. The first and second elastic components are both located within the triangular structure. The elastic components cooperate with the positioning plate to apply force to the limiting plate located in the middle, thereby limiting the position of the limiting plate and preventing it from tilting during installation. At the same time, the triangular structure formed by the positioning plate and the side walls has high stability and uniform force application, which can improve the stability of the UAV during flight.

[0009] In some embodiments, the partition plate has fixing screw holes at each of its four corners, which are located within the triangular structure formed between the positioning plate and the sidewall. A gap is provided between the two sides of the positioning plate and the two sidewalls, and a limiting groove is provided at the bottom of the positioning plate. The fixing screw holes are positioned to match the fixing screws, allowing them to connect and secure the lifting rotor. The limiting groove engages with the limiting protrusions on the limiting plate, ensuring a tighter connection between the limiting plate and the positioning plate and preventing detachment.

[0010] In some embodiments, both the first elastic component and the second elastic component include a base plate, a spring, and a movable plate. The side of the base plate is connected to the side wall, and several springs are connected to the surface of the base plate. The base plate is connected to the L-shaped movable plate via the springs, and the movement path of the movable plate is parallel to the extension direction of the corresponding side wall. When the lifting rotor needs to be installed, the limiting plate is inserted between the first elastic component, the second elastic component, and the positioning plate. Since the movable plate is fixed by the springs, it has a certain amount of movement space, which can accommodate limiting plates of different thicknesses and provide basic positioning for the limiting plates, preventing the screw holes from being misplaced when fixing the screws later. The L-shaped movable plate protects the springs located inside, preventing them from being exposed. The movement path of the movable plate is adapted to the side wall, facilitating the installation of the lifting rotor.

[0011] In some embodiments, the limiting plate includes two positioning posts and an upper connecting bridge and a lower connecting bridge connected between the two positioning posts. The outer sides of the two positioning posts are respectively abutted against the two side walls, and the rear side of the positioning posts is abutted against the movable plate. The positioning posts are provided to cooperate with the movable plate and guide the movement path of the limiting plate during installation. A space is reserved between the upper connecting bridge and the lower connecting bridge to facilitate the installation and removal of fixing screws.

[0012] In some embodiments, the upper connecting bridge is connected to the rotor arm, and the lower connecting bridge is vertically screwed with the fixing screw, which is screwed into the fixing screw hole. The bottom of the lower connecting bridge is also provided with a limiting protrusion, which is adapted to the limiting groove. When the limiting plate is inserted into the elastic fixing device, the elastic movable plate provides basic positioning for the limiting plate. The user tightens the fixing screw to make the limiting plate and the partition plate tightly connected. At the same time, the limiting protrusion at the bottom of the limiting plate is engaged in the limiting groove on the positioning plate, fixing their positions. When it is necessary to remove the lifting rotor, loosen the fixing screw and shake the limiting plate slightly to disengage it from the connection, thereby replacing the new lifting rotor.

[0013] In some embodiments, the system also includes an infrared thermal imager, a radio wave life detector, and a power supply battery. The infrared thermal imager and the radio wave life detector are both located on the outside of the cargo box and electrically connected to the control center. The power supply battery is located in the lower layer and is electrically connected to the lifting rotor, the electric four-wheel drive chassis, and the control center. The infrared thermal imager and radio wave life detector are used to monitor the location and vital signs of the trapped personnel in real time. The power supply battery provides continuous power for the operation of the drone. The specific structure of the infrared thermal imager, radio wave life detector and power supply battery can be referred to the prior art, and will not be elaborated here. However, it should be understood that the lower layer of the drone is also equipped with other drone components such as gyroscope, accelerometer, and GPS to realize the basic obstacle avoidance and positioning functions of the drone. These technical functions are common in the field and well known to those skilled in the art. They are not the focus of protection in this application, so they will not be elaborated here. However, this does not mean that the technical solution of this application lacks the necessary components to realize the flight of the drone. The algorithm for detecting the vital signs and thermal imaging contours of the trapped personnel is similar and will not be described in detail.

[0014] In some embodiments, the partition is provided with standardized interface slots, which include several mechanical interface slots and electrical interface slots. These standardized interface slots are electrically connected to the control center. The standardized interface slots, with multiple mechanical and electrical interface slots, enable quick replacement. Functional components and the lifting rotor uniformly use standard mechanical or electrical interfaces. After quick replacement and installation, the interfaces are directly connected to the control center, avoiding the cumbersome installation and potential disconnection issues caused by multiple transfers. When the lifting rotor needs to be disassembled, the interface can be directly unplugged to disconnect it from the control center.

[0015] In some embodiments, the infrared thermal imager, the radio wave life detector, the lifting rotor, and the power supply battery are all equipped with communication data lines, which are connected to the mechanical interface slot or the electrical interface slot on the standardized interface slot. The infrared thermal imager, radio wave life detector, lifting rotor, and power supply battery are all connected via communication data lines, facilitating quick replacement and saving rescue time.

[0016] By adopting the above technical solution, the beneficial effects of this utility model are:

[0017] This invention features a drone with a cargo box, enabling it to carry emergency relief supplies such as first aid kits, oxygen cylinders, and protective clothing to higher floors. The drone also has a driving function, allowing it to travel between buildings and accurately deliver supplies to trapped individuals. However, due to the high temperatures of a fire, the outer rotor of the drone often becomes damaged after several flights and transports. Therefore, a quick-detachable and replaceable lifting rotor is incorporated. This is achieved by inserting a limiting plate into an elastic fixing device and tightening it with screws, ensuring a secure connection and easy replacement of the lifting rotor.

[0046] According to some embodiments of the present invention, the present invention provides a box-type drone for high-altitude and high-rise building rescue, including a cargo box 1 with an internal cavity 2, lifting rotors 3 detachably disposed at the four corners of the cavity 2 and extending outward from the cargo box 1, an electric four-wheel drive chassis 4 disposed on the bottom side of the cargo box 1, and a control center located in the cavity 2. The control center is electrically connected to the lifting rotors 3 and the electric four-wheel drive chassis 4. The cavity 2 is divided into an upper layer and a lower layer by a partition 5. The control center is disposed in the lower layer, and the lifting rotors 3 are disposed in the upper layer. The lifting rotors 3 include rotor arms 31, limiting plates 32, and fixing screws 33. Each of the four corners of the cavity 2 is provided with an elastic fixing device 6, and the elastic fixing device 6 is located in the upper layer. The lifting rotors 3 are fixed in the cavity 2 by the elastic fixing device 6.

[0047] The upper layer of the cargo box 1 is used to store emergency rescue supplies, such as first aid kits, oxygen cylinders, and protective clothing. The lower layer is the central hub for controlling the entire drone operation. To prevent high external temperatures from intruding into the control center, a partition 5 is installed to separate the two functional areas for protection. The lifting rotor 3 is used to enable high-altitude flight, and the electric four-wheel drive chassis 4 allows the cargo box 1 to move between high-rise building corridors, enabling precise delivery of supplies to trapped personnel. At the same time, due to the high-temperature environment, the drone rotor located on the outside often suffers damage after several flights and transports. Therefore, the lifting rotor 3 can be quickly disassembled and replaced, saving rescue time. Preferably, the cargo box 1 is made of lightweight material and coated with a high-temperature resistant layer on the outside to protect the rescue supplies. The top cover of the cargo box 1 should be easy to open and should not have a locking structure, so that trapped personnel can quickly access the internal items. The specific structure of the rotor arm 31 and the electric four-wheel drive chassis 4 can refer to existing technologies.

[0048] The box-type drone also includes an infrared thermal imager 7, a radio wave life detector 8, and a power supply battery. The infrared thermal imager 7 and the radio wave life detector 8 are both located on the outside of the cargo box 1 and are electrically connected to the control center. The power supply battery is located in the lower layer and is electrically connected to the lifting rotor 3, the electric four-wheel drive chassis 4, and the control center. The infrared thermal imager 7 and the radio wave life detector 8 are used to monitor the location and vital signs of the trapped personnel in real time. The power supply battery provides continuous power for the operation of the drone. The specific structure of the infrared thermal imager 7, the radio wave life detector 8 and the power supply battery can be referred to the prior art, and will not be elaborated here. However, it should be understood that the lower layer of the drone is also equipped with other drone components such as gyroscopes, accelerometers, and GPS, which are used to realize the basic obstacle avoidance and positioning functions of the drone.

However, this does not mean that the technical solution of this application lacks the necessary components to realize the flight of the drone. The algorithm for detecting the vital signs and thermal imaging contours of the trapped personnel is similar and will not be described in detail.

[0049] The partition 5 is equipped with a standardized interface slot 9, which includes several mechanical and electrical interface slots. This standardized interface slot 9 is electrically connected to the control center. The standardized interface slot 9, with its multiple mechanical and electrical interface slots, enables quick replacement. Functional components and the lifting rotor 3 uniformly use standard mechanical or electrical interfaces. After quick replacement and installation, the interface is directly connected to the control center, avoiding the cumbersome installation and potential disconnection issues caused by multiple transfers.

[0051] Reference Figure 2 , Figure 2 This is a schematic diagram of the internal structure of the receiving cavity in some embodiments of this utility model.

[0052] Optionally, according to some embodiments of this utility model, one end of the rotor arm 31 is provided with the limiting plate 32, which extends downward and is engaged in the elastic fixing device 6. The other end of the rotor arm 31 extends to the outside of the cargo box 1, and the fixing screw 33 is rotatably connected to the limiting plate 32. The limiting plate 32 extends downward into the receiving cavity 2 and cooperates with the elastic fixing device 6 to fix the current position of the lifting rotor 3. At the same time, in order to make the connection between the lifting rotor 3 and the box more tight, the fixing screw 33 is connected to the partition 5, so that the lifting rotor 3 can drive the cargo box 1 to fly.

[0053] The elastic fixing device 6 includes a first elastic component, a second elastic component, and a positioning plate 61. The first and second elastic components are respectively disposed on the two side walls of the cargo box 1. The positioning plate 61 is disposed on the partition 5 and forms a triangular structure between the two side walls. The first and second elastic components are both located within the triangular structure. The elastic components cooperate with the positioning plate 61 to apply force to the limiting plate 32 located in the middle, thereby limiting the position of the limiting plate 32 and preventing it from tilting during installation. At the same time, the triangular structure formed by the positioning plate 61 and the side walls has high stability and uniform force application, which can improve the stability of the UAV during flight.

[0054] The partition 5 has fixing screw holes at each of its four corners, located within the triangular structure formed between the positioning plate 61 and the side wall. There are gaps between the two sides of the positioning plate 61 and the two side walls, and a limiting groove is provided at the bottom of the positioning plate 61. The fixing screw holes are positioned to match the fixing screws 33, allowing them to connect and secure the lifting rotor 3. The limiting groove engages with the limiting protrusions 324 on the limiting plate 32, ensuring a tighter connection between the limiting plate 32 and the positioning plate 61 and preventing detachment.

[0055] Both the first and second elastic components include a base plate 62, springs 63, and a movable plate 64. The base plate 62 is connected to the side wall, and several springs 63 are connected to the surface of the base plate 62. The L-shaped movable plate 64 is connected to the base plate 62 via the springs 63. The movement path of the movable plate 64 is parallel to the extension direction of the corresponding side wall. When the lifting rotor 3 needs to be installed, the limiting plate 32 is inserted between the first elastic component, the second elastic component, and the positioning plate 61. Since the movable plate 64 is fixed by the springs 63, it has a certain amount of room to move, thus accommodating limiting plates 32 of different thicknesses and providing basic positioning for the limiting plates 32. This prevents the screw holes from being misplaced when fixing the screws 33. The L-shaped movable plate 64 protects the internal springs 63, preventing them from being exposed. The movement path of the movable plate 64 is adapted to the side wall, facilitating the installation of the lifting rotor 3.

[0056] The limiting plate 32 includes two positioning posts 321 and an upper connecting bridge 322 and a lower connecting bridge 323 connecting the two positioning posts 321. The outer sides of the two positioning posts 321 are respectively abutted against the two side walls, and the rear side of the positioning posts 321 is abutted against the movable plate 64. The positioning posts 321 are provided to cooperate with the movable plate 64 and guide the movement path of the limiting plate 32 during installation. A space is reserved between the upper connecting bridge 322 and the lower connecting bridge 323 to facilitate the installation and removal of the fixing screws 33.

The bottom of the lower connecting bridge 323 is also provided with a limiting protrusion 324, which is adapted to the limiting groove. When the limiting plate 32 is inserted into the elastic fixing device 6, the elastic movable plate 64 provides basic positioning for the limiting plate 32. The user tightens the fixing screw 33 to make the limiting plate 32 and the partition 5 tightly connected. At the same time, the limiting protrusion 324 at the bottom of the limiting plate 32 is engaged in the limiting groove on the positioning plate 61, fixing their positions. When it is necessary to remove the lifting rotor 3, loosen the fixing screw 33 and shake the limiting plate 32 slightly to disengage it, thereby replacing the new lifting rotor 3.
