Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicle components, and in particular to a unmanned aerial vehicle carrying mechanism for carrying and transporting an unmanned aerial vehicle. Background Art

[0002] Unmanned aerial vehicles (UAVs), also known as drones, are unmanned aircraft controlled by radio remote control and self-contained programmable controls. Drones are a general term for unmanned aerial vehicles (UAVs), which can be technically categorized into: unmanned helicopters, unmanned fixed-wing aircraft, unmanned multi-rotor aircraft, unmanned airships, and unmanned paragliders.

[0003] Although unmanned multi-rotor aircraft can currently lift some equipment for transfer or high-altitude operations, in actual use, when faced with dangerous operations such as troubleshooting, search and rescue, and explosive disposal on floors, drones find it difficult to operate stably on floors. Although unmanned vehicles are suitable for the above-mentioned dangerous operations, their mobility is limited. If operating on high floors, unmanned vehicles may need to continuously climb stairs or other obstacles to reach the scene, which causes lags when unmanned vehicles perform dangerous operations on high floors.

[0004] In view of this, it is particularly important to design and manufacture a drone carrying mechanism that can carry and transport an unmanned vehicle into a floor, when the drone performs dangerous operations on the floor. Summary of the Invention

[0005] The purpose of the present invention is to propose a drone carrying mechanism for carrying and transporting unmanned vehicles in order to combine the flexibility of a drone and the stability of an unmanned vehicle working on a floor, and to solve the problem that unmanned vehicles currently have difficulty in quickly entering a floor to perform dangerous operations.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A drone carrying mechanism for carrying and transporting an unmanned vehicle comprises a drone and an unmanned vehicle, wherein a fixing plate is detachably mounted on the belly of the drone, and the lower end of the fixing plate is symmetrically fixedly connected to two support frames with open front ends, the unmanned vehicle is limited between the two support frames by a first magnetic locking mechanism, and a rotating frame is rotatably mounted on the front end of the support frame via a torsion spring rotating shaft, a second magnetic locking mechanism is provided between the fixing plate and the rotating frame for keeping the rotating frame continuously closed at the front end opening of the support frame, and a window breaking mechanism is provided at the lower end of the fixing plate for assisting the unmanned vehicle in entering a building through a glass window.

[0008] As a further description of the above technical solution:

[0009] The first magnetic locking mechanism includes a first electromagnet laterally fixed between the rear ends of the two support frames and a magnetic suction block fixed in the middle of the rear end of the unmanned vehicle and in contact with the first electromagnet.

[0010] As a further description of the above technical solution:

[0011] The second magnetic locking mechanism includes a magnetic sleeve fixed on the free end of the rotating frame and a second electromagnet symmetrically fixed on the front side of the lower end of the fixing plate and corresponding to the magnetic sleeve.

[0012] As a further description of the above technical solution:

[0013] Ground wheels with a concave middle portion are installed on both sides of the body of the unmanned vehicle, and anti-skid guide rails facing and matching the ground wheels are installed on the two support frames and the rotating frame.

[0014] As a further description of the above technical solution:

[0015] The anti-slip guide rail is made of vulcanized rubber material.

[0016] As a further description of the above technical solution:

[0017] The window breaking mechanism includes a launching shell installed in the middle of the lower end of the fixing plate and facing the front area of the UAV, two air cavities symmetrically opened on the inner side of the launching shell, a compressed air bottle detachably installed on the rear end of the launching shell and connected to the two air cavities, a window breaking hammer head movably installed on the inner side of the air cavity, and a locking part arranged between the window breaking hammer heads at the lower end of the launching shell.

[0018] As a further description of the above technical solution:

[0019] The locking part includes an electromagnetic lock installed at the lower end of the launching shell, a one-way sliding lock block movably installed at the upper end of the electromagnetic lock and passing through the launching shell, and a one-way lock groove opened at the rear end of the window breaking hammer head and corresponding to the one-way sliding lock block.

[0020] As a further description of the above technical solution:

[0021] A spiral extrusion spring is installed on the inner side of the air cavity between the compressed air bottle and the window breaking hammer head.

[0022] As a further description of the above technical solution:

[0023] The front end of the window-breaking hammer head is in a pointed cone shape, a sealing ring is sleeved on the front side of the one-way lock groove of the window-breaking hammer head, and the window-breaking hammer head is made of tungsten steel material.

[0024] As a further description of the above technical solution:

[0025] Ground support blocks that first contact the ground are installed on the front and rear sides of the lower ends of the two support frames, and the front ends of the two ground support blocks arranged on the front side are integrally fixedly connected with limit blocks that keep the rotating frame and the lower ends of the support frames horizontally distributed.

[0026] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0027] 1. In the present invention, the original support frame structure of the drone is scientifically and rationally improved, and the support frame is set into a split structure. A rotating frame that can be rotated to a horizontal state and a second electromagnet that maintains the rotating frame in a closed state are set between the support frame and the fixed plate. An anti-slip guide rail for the stable movement of the unmanned vehicle is set on the support frame, and a first electromagnet and a magnetic block are set between the support frame and the unmanned vehicle. When the first electromagnet and the second electromagnet are both powered off, the rotating frame can rotate outward to a horizontal state under the action of the torsional force of the torsion spring shaft, and the unmanned vehicle can be separated from the binding of the support frame. At this time, when operating the unmanned vehicle, the unmanned vehicle can be stably sent into the window or the floor through the anti-slip guide rails on the support frame and the rotating frame. This structure can combine the flexibility of the drone outside the floor with the stability of the unmanned vehicle inside the floor, so that the drone can carry the unmanned vehicle quickly into the designated floor to perform dangerous on-site operations, effectively improving the efficiency of the unmanned vehicle transfer, thereby improving the efficiency of the unmanned vehicle in performing dangerous operations on the floor.

[0028] 2. In the present invention, a launching shell, a compressed air bottle, a window-breaking hammer, a spiral extrusion spring and an electromagnetic lock are arranged under the fixed plate. Under normal circumstances, the one-way sliding lock block on the electromagnetic lock will be locked with the one-way lock groove of the window-breaking hammer. At this time, the spiral extrusion spring will be in a compressed state. At the same time, the compressed air bottle will generate a certain intensity of air pressure in the air cavity. When the electromagnetic lock is energized, the one-way sliding lock block can be separated from the one-way lock groove. Under the combined action of elastic force and air pressure, the window-breaking hammer will hit the glass at high speed along the air cavity, breaking the glass on the window. This structure can break the glass on the window, preventing the glass from blocking the unmanned vehicle from entering the window, thereby ensuring the passability of the drone when carrying the unmanned vehicle.

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0036] See also Figure 1-4 The present invention provides a technical solution: a drone carrying mechanism for carrying and transporting an unmanned vehicle, comprising a drone 1 and an unmanned vehicle 2, a fixing plate 3 being detachably mounted on the belly of the drone 1, two support frames 301 with open front ends being symmetrically fixedly connected at the lower end of the fixing plate 3, the unmanned vehicle 2 being limited between the two support frames 301 by a first magnetic locking mechanism, a rotating frame 303 being rotatably mounted on the front end of the support frame 301 via a torsion spring rotating shaft 302, a second magnetic locking mechanism being arranged between the fixing plate 3 and the rotating frame 303 for keeping the rotating frame 303 continuously closing the opening at the front end of the support frame 301, a window breaking mechanism being arranged at the lower end of the fixing plate 3 for assisting the unmanned vehicle 2 in entering a building through a glass window.

[0037] Specifically, such as Figure 1-3 As shown, the first magnetic locking mechanism includes a first electromagnet 5 fixed horizontally between the rear ends of the two support frames 301 and a magnetic block 202 fixed in the middle of the rear end of the unmanned vehicle 2 and fitted with the first electromagnet 5. When the first electromagnet 5 is energized, an electromagnetic force will be generated. Under the action of the magnetic force, the magnetic block 202 at the rear end of the unmanned vehicle 2 can be adsorbed and magnetically fitted with the first electromagnet 5. At this time, a magnetic fixed connection will be established between the unmanned vehicle 2 and the support frame 301.

[0038] Specifically, such as Figure 1-4As shown, the second magnetic locking mechanism includes a magnetic sleeve 304 fixed on the free end of the rotating frame 303 and a second electromagnet 8 symmetrically fixed on the front side of the lower end of the fixed plate 3 and corresponding to the magnetic sleeve 304. When the second electromagnet 8 is energized, an electromagnetic force is generated. Under the action of the magnetic force, the magnetic sleeve 304 on the rotating frame 303 can be magnetically fixed. The electromagnetic force generated by the second electromagnet 8 is greater than the torsional force of the torsion spring shaft 302. This allows the rotating frame 303 to be unfolded to a horizontal state under the action of gravity and torsional force when the second electromagnet 8 is de-energized.

[0039] Specifically, such as Figure 1-3 As shown, ground wheels 201 with a concave middle part are installed on both sides of the body of the unmanned vehicle 2, and anti-skid guide rails 4 facing and matching the ground wheels 201 are installed on the two support frames 301 and the rotating frame 303. The anti-skid guide rails 4 are made of vulcanized rubber material. The selection of this material, combined with the concave ground wheels 201, can prevent the unmanned vehicle 2 from being subjected to force deviation and shaking during transportation, and at the same time reduce the occurrence of slipping and idling problems of the ground wheels 201 of the unmanned vehicle 2 during walking, thereby improving the stability of the unmanned vehicle 2 during transportation and walking.

[0040] Specifically, such as Figure 1-4 As shown, the window breaking mechanism includes a launch shell 6 installed in the middle of the lower end of the fixing plate 3 and facing the front area of the drone 1, two air cavities 601 symmetrically opened on the inner side of the launch shell 6, a compressed air bottle 602 detachably installed at the rear end of the launch shell 6 and connected to the two air cavities 601, a window breaking hammer 7 movably installed on the inner side of the air cavity 601 and a locking part provided between the window breaking hammer 7 at the lower end of the launch shell 6, the locking part includes an electromagnetic lock 9 installed at the lower end of the launch shell 6, a movable upper end of the electromagnetic lock 9 and passing through the launch shell 6 and a one-way locking groove 701 provided at the rear end of the window-breaking hammer head 7 and corresponding to the one-way sliding locking block 901. At the same time, a spiral extrusion spring 10 is installed on the inner side of the air cavity 601 between the compressed air bottle 602 and the window-breaking hammer head 7. On the one hand, the one-way sliding locking block 901 on the electromagnetic lock 9 and the one-way locking groove 701 on the window-breaking hammer head 7 can be locked more stably. On the other hand, the window-breaking hammer head 7 can generate an outward elastic extrusion force, thereby further enhancing the kinetic energy of the window-breaking hammer head 7 ejected through the air cavity 601.

[0041] The front end of the window-breaking hammer head 7 is in the shape of a pointed cone. A sealing ring 702 is provided on the front side of the one-way locking groove 701 of the window-breaking hammer head 7. The window-breaking hammer head 7 is made of tungsten steel. In actual use, other high-strength and high-hardness metal materials can also be used to make the window-breaking hammer head 7.

[0042] Specifically, such as Figure 1-3As shown, the front and rear sides of the lower ends of the two support frames 301 are both equipped with ground support blocks 305 that first contact the ground. The front ends of the two ground support blocks 305 arranged on the front side are integrally connected with a limit block 306 that keeps the rotating frame 303 and the lower end of the support frame 301 horizontally distributed. The limit block 306 can keep the rotating frame 303 and the support frame 301 in a horizontal state, preventing the rotating frame 303 from excessively deflecting under the action of torsional force, thereby improving the stability of the unmanned vehicle 2 walking through the support frame 301 and the anti-slip guide rail 4 on the rotating frame 303.

[0043] Working principle: When in use, the fixing plate 3 can be fixed on the belly of the drone 1 through fasteners, and then the control circuit of the drone carrying mechanism can be connected to the control terminal of the drone 1, so that the carrying mechanism can be assembled on the drone 1. During actual use, the ground wheel 201 of the unmanned vehicle 2 can be placed and buckled between the anti-slip guide rails 4 of the two support frames 301, and then the unmanned vehicle 2 can be slid backward. When the magnetic block 202 behind the unmanned vehicle 2 fits the first electromagnet 5, the first electromagnet 5 can be controlled to be energized. At this time, the unmanned vehicle 2 will be locked between the two support frames 301. Then the rotating frame 303 is folded inward so that the magnetic sleeve 304 on the support frame 301 fits the second electromagnet 8, and the second electromagnet 8 can be controlled to be energized. At this time, the rotating frame 303 will be locked between the fixing plate 3 and the support frame 301, and the drone 1 can be operated to transport the unmanned vehicle 2. After arriving at the designated floor, if there is glass on the window outside the floor, it is necessary to break the window to lift the unmanned vehicle 2 is sent into the floor, the operator can operate the electromagnetic lock 9 to energize. Under the action of electromagnetic force, the one-way sliding lock block 901 will move downward out of the one-way lock groove 701 on the window breaking hammer 7. At this time, under the elastic force of the spiral extrusion spring 10 and the air pressure of the compressed air bottle 602, the window breaking hammer 7 can move forward at high speed along the air cavity 601 to hit the glass, breaking the glass on the window. When the unmanned vehicle 2 needs to be transported to the floor or the window, the operator can control the first electromagnet 5 and the second electromagnet 8 to be de-energized. When the first electromagnet 5 is de-energized, the locking state of the unmanned vehicle 2 between the two support frames 301 is released. When the second electromagnet 8 is de-energized, the rotating frame 303 will rotate and adjust the horizontal state under the torsional force of the torsion spring shaft 302 and the limiting action of the limit block 306. At this time, when operating the unmanned vehicle 2, the unmanned vehicle 2 can be transported to the floor or the window through the anti-slip guide rails 4 on the support frame 301 and the rotating frame 303.
