[0030] The application will be described in further detail below with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the related application, and are not a limitation on the application. In addition, it should be noted that only parts related to the application are shown in the drawings for ease of description.

[0031] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the drawings and embodiments.

[0032] Embodiment 1

[0033] Please refer to Figure 1 and Figure 2 The overall structure schematic diagram and top view of the emergency fire-fighting material transport and throwing unmanned aerial vehicle provided by the present embodiment are shown, which comprises:

[0034] The unmanned aerial vehicle body 1 has multiple arms 2 on the outer wall of the unmanned aerial vehicle body 1 along the circumference, and each arm 2 is provided with a power assembly at the end away from the unmanned aerial vehicle body 1, which is used to provide flight power for the unmanned aerial vehicle;

[0035] The carrying assembly is arranged between the two landing gears 4 of the unmanned aerial vehicle, and comprises a connecting base plate 5 and a carrying movable part 6 connected with the connecting base plate 5. The connecting base plate 5 is connected with the two landing gears 4. The carrying movable part comprises a detachably connected sliding plate 61 and a fixed plate 62.

[0036] The sliding plate 61 is used to connect with the object to be carried on the unmanned aerial vehicle, and the fixed plate 62 is used to connect with the pre-set connecting hole position on the connecting base plate 5.

[0037] In the embodiment of the present application, the unmanned aerial vehicle main body 1 is the main body structure of the unmanned aerial vehicle, and a central control system integrated with data and communication links is arranged in the unmanned aerial vehicle main body 1. The central control system cooperates with various sensors and controllers to realize functions such as monitoring the flight state of the unmanned aerial vehicle, adjusting the attitude of the unmanned aerial vehicle, planning the flight path of the unmanned aerial vehicle, and communicating with different devices by using some series of logical operations integrated by itself. Therefore, the unmanned aerial vehicle main body 1 can also be called the core of the entire unmanned aerial vehicle. Specifically, the unmanned aerial vehicle main body 1 also needs to be provided with at least a power module 7, a GPS system 13, and an image acquisition system 14. The power module 7 is used to provide power for the central control system, the GPS system 13, and the image acquisition system 14. The central control system, the GPS system 13, and the image acquisition system 14 cooperate with each other to control the flight of the unmanned aerial vehicle. The GPS system 13 can provide path planning, and the image acquisition system 14 can guide the flight of the unmanned aerial vehicle in real time by acquiring images and videos, including but not limited to avoiding dangerous objects, collecting site information, and other functions. Here, no longer be described in detail.

[0038] In addition, the outer wall of the unmanned aerial vehicle main body 1 is uniformly provided with a plurality of arms 2 mounted with power assemblies along the circumference thereof. The arms 2 and the power assemblies are used to provide the flight power of the unmanned aerial vehicle, so that the unmanned aerial vehicle can take off. For example, the unmanned aerial vehicle main body 1 in the embodiment of the present application has six arms 2, and the six arms 2 are consistent in specification and are uniformly distributed along the outer wall of the unmanned aerial vehicle main body 1. The specific number and arrangement are not specially limited in the present application. Correspondingly, a carrying assembly is arranged between the landing gear 4 of the unmanned aerial vehicle to complete the fixation and transportation of materials or some objects that need to be carried on the unmanned aerial vehicle. The carrying assembly includes a connecting base plate 5, which can be directly fixed with the unmanned aerial vehicle as an installation medium for external objects (devices and materials). Since the disassembly efficiency of external objects and the wear caused to the unmanned aerial vehicle during the complex heavy carrying process are problems worthy of attention, the carrying assembly in the embodiment of the present application further includes a carrying movable part 6 detachably connected to the connecting base plate 5.

[0039] Further, referring to Figures 4-6The carrying movable part 6 is composed of a detachable sliding plate 61 and a fixed plate 62. The sliding plate 61 is used to connect with the external object to be carried on the unmanned aerial vehicle. The sliding plate 61 has a simple structure and a relatively low manufacturing cost. When connecting with the external object, a part of the cost can be saved even if the external object needs to be frequently replaced. In an emergency, the unmanned aerial vehicle can be controlled to fly back to the starting point after the sliding plate 61 is separated from the fixed plate 62, without waiting for the external object to be completely unloaded from the unmanned aerial vehicle. The fixed plate 62 is used to connect with the connecting base plate 5. The fixed plate 62 has a relatively complex structure and a relatively high manufacturing cost. In the embodiment, some sensors for monitoring the weight and state of the external object are usually installed in the fixed plate 62. Therefore, the fixed plate 62 needs to have some installation cavities. It can be seen that the carrying movable part 6 can realize the rapid unloading of the external object by quickly detaching the sliding plate 61 from the fixed plate 62, and the unmanned aerial vehicle itself will not be damaged due to frequent detachment.

[0040] It should be noted that the fixed plate 62, the sliding plate 63 and the connecting base plate 5 are all provided with a plurality of connection holes. The connection holes are designed to achieve the necessary connection and provide convenience for connection. For example, when connecting with some external objects of different types, the connection position of the carrying movable part 6 needs to be adjusted. At this time, the connection position of the fixed plate 62 and the connecting base plate 5 can be changed to achieve the adjustment. For details, see Figure 1 It can also be seen that the connecting base plate 5 is provided with a plurality of connection holes.

[0041] In a preferred embodiment, referring to Figure 1 , Figure 7 and Figure 8 , the arm 2 comprises a folding structure 8 connected with the unmanned aerial vehicle body 1 and a connecting arm 9 arranged at one end of the folding structure 8 away from the unmanned aerial vehicle body 1; the power assembly is arranged on the connecting arm 9; in the extension direction of the arm 2, the folding point of the folding structure 8 is located at the end of the arm 2 close to the unmanned aerial vehicle body 1.

[0042] Specifically, since the unmanned aerial vehicle needs to be stored for some time except for the time when it needs to perform a task, the storage convenience of the unmanned aerial vehicle also needs to be concerned. Therefore, in the embodiment, the arm 2 comprises the folding structure 8 and the connecting arm 9. The folding structure 8 is used to bend the connecting arm 9 downward to reduce the space occupied by the arm 2. The connecting arm 9 has a relatively long specification and is connected with the power assembly. When the unmanned aerial vehicle performs a task, the connecting arm 9 is stretched and assumes a flight posture.

[0043] In a preferred embodiment, referring to Figure 7 and Figure 8, the folding structure 8 comprises: two movably connected first sleeves 81 and second sleeves 82; the first sleeve 81 is connected with the unmanned aerial vehicle body 1, the bottom of the end of the first sleeve 81 away from the unmanned aerial vehicle body 1 is movably connected with the first connecting block 821 of the second sleeve 82 through the first pin shaft 85, and the top of the end of the first sleeve 81 away from the unmanned aerial vehicle body 1 is rotatably connected with a pull block 83, the pull block 83 is hollow inside and contains a movable shaft 84; one end of the movable shaft 84 is movably connected with the end of the pull block 83 away from the first sleeve 81, and the other end thereof is movably connected with the second connecting block 822 of the top of the second sleeve 82, so that the second sleeve 82 can swing around the first pin shaft 85 and be recovered.

[0044] Specifically, the connection of the folding structure 8 can be as described above, when the arms 2 are folded and stored, the pull block 83 can be pulled first, at this time, the movable shaft 84 moves outward and drives the second sleeve 82 to move outward a certain distance through the feature that the movable shaft 84 is movably connected with the second connecting block 822 of the top of the second sleeve 82, and at the same time, the second sleeve 82 has a space for folding downward around the first pin shaft, when the second sleeve 82 folds downward, the movable shaft 84 also follows it downward, which also plays a role in limiting the folding range.

[0045] In a preferred embodiment, referring to Figure 1 and Figure 3 , the power assembly comprises: a containing shell 10, the containing shell 10 is internally provided with a driving member, the driving end of the driving member extends to the outside of the containing shell 10 and is connected in transmission with the propeller 11; the driving member is used to drive the propeller 11 to rotate, so as to provide flight power for the unmanned aerial vehicle.

[0046] Specifically, in the embodiment of the application, the power assembly adopts the form of the propeller 11, generally, the power assemblies on each arm 2 adopt the same specification; the power assembly first has a containing shell 10 for protecting the driving member, so as to avoid the influence of the function of the unmanned aerial vehicle when encountering bad weather, and the power source of the power assembly is provided by the driving member installed in the containing shell 10, the driving member can be selected as a motor with large lift, and the motor with large lift is used to drive the propeller 11 to rotate, so as to ensure that the unmanned aerial vehicle has large carrying capacity.

[0047] It should be noted that the structures of the propellers 11 in the power assemblies are consistent, and are reasonable and appropriate structural forms obtained by technicians according to experience and tests, so no special limitation is made here.

[0048] In a preferred embodiment, referring to Figure 3The propeller 11 comprises a connecting frame 12, the connecting frame 12 is in transmission connection with the driving end of the driving member, two rotating shafts are arranged on the connecting frame 12 in intervals, and one helical blade is sleeved on each rotating shaft and can rotate along the rotating shaft.

[0049] Specifically, the entire unmanned aerial vehicle occupies space except the longer arm 2, and the longer propeller 11 with helical blades also affects the storage of the unmanned aerial vehicle, so in the embodiment, the propeller 11 comprises a connecting frame 12 for completing the connection function, and two rotating shafts are arranged on the connecting frame 12 in intervals, and the rotating shafts are designed to realize the rotating storage of the two helical blades, for example, rotating the two helical blades by a certain angle to make the two helical blades close to each other, so that the area occupied by the two helical blades as a whole is greatly reduced.

[0050] In a preferred embodiment, referring to Figure 5 and Figure 6 The fixed plate 62 and the sliding plate 61 are respectively provided with a sliding groove 63 and a sliding protrusion 64 matched with each other, and the fixed plate 62 is further in clamping connection with the sliding plate 61 in a direction perpendicular to the extending direction of the sliding groove 63 through a locking member 65.

[0051] An opening 66 is formed in the side edge of the sliding plate 61, and the locking member 65 is provided with a clamping protrusion 67 matched with the opening 66, and when the locking member 65 is in threaded connection with the fixed plate 62, the clamping protrusion 67 can be clamped to the opening 66.

[0052] Specifically, the above-mentioned “quick disassembly connection” is realized, the fixed plate 62 and the sliding plate 61 are provided with the sliding groove 63 and the sliding protrusion 64 matched with each other, and in order to ensure the stability of the sliding connection, the sliding protrusion 64 has at least one inclined edge extending away from the axis of the sliding plate 61, and the sliding groove 63 is matched with the form and also has an inclined angle profile; in this way, when the sliding groove 63 and the sliding protrusion 64 are in sliding connection, the fixed plate 62 and the sliding plate 61 can be locked in the vertical direction (under the clamping of the inclined edge and the inclined angle groove); further, the fixed plate 62 is in clamping connection with the sliding plate 61 in the direction perpendicular to the extending direction of the sliding groove 63, that is, in the horizontal direction, through the clamping of the clamping protrusion 67 provided on the top of the locking member 65 to the opening 66 in the edge of the sliding plate 61 when the locking member 65 is in threaded connection with the fixed plate 62, so that the fixed plate 62 and the sliding plate 61 are simply clamped in the horizontal and vertical directions, which not only ensures the convenience of disassembly but also guarantees the stability of the connection.

[0053] Based on the above description, the application provides an emergency fire-fighting material transportation and throwing unmanned aerial vehicle, and the specific working principle is as follows: after the equipment or material to be carried is determined, it is first fixed on the sliding plate 61, at this time, the sliding plate 61 can be connected with the fixed plate 62 after being fixed, or after the equipment or material is fixed, the sliding groove 63 and the sliding protrusion 64 are connected, then the locking piece 65 is screwed into the inside of the fixed plate 62 until the clamping protrusion 67 is clamped with the opening 66 to be completed; after the equipment or material is carried, the starting instruction can be sent to the controller of the driving piece by the central control system, and the driving piece drives the rotation of each propeller 11, at this time, the unmanned aerial vehicle takes off, and the equipment or material is transported to the designated destination by the central control system according to the pre-designed path; when the unmanned aerial vehicle is idle, the occupation space of the whole unmanned aerial vehicle can be reduced by the ingenious setting of the folding structure 8 and the propeller 11, and the user can store it conveniently.
