Description

Technical Field

[0001] The present disclosure belongs to the technical field of multi-functional emergency rescue multi-rotor drones, and particularly relates to a multi-functional emergency rescue multi-rotor drone. Background Art

[0002] Drones have been widely used in many fields such as aerial photography, rescue, forest fire prevention, and security. They mainly consist of a fuselage and multiple rotors. The flight postures of traditional drones are mostly fixed. Therefore, when flying indoors and outdoors, especially in relatively complex environments such as cities and jungles, since some gaps are difficult for the drone to pass through, it is easy to operate improperly and cause the drone to collide with objects in the environment, resulting in damage to the drone equipment.

[0003] Moreover, in the prior art, when protecting the rotors of the drone, most of them protect the drone through a fixed drone frame. When a collision occurs, it is easy to cause the drone frame to break and deform, or the reaction force to cause greater damage to the rotors of the drone, which may lead to the situation of the fuselage losing control or falling. That is, when a collision occurs, the existing protection mechanism does not have a force-releasing function and the protection effect is poor. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is to provide a multi-functional emergency rescue multi-rotor drone that can change between the states of normal flight, vertical flight, and rotor deflection flight, enabling the drone to move in open environments and narrow environments, and be able to rotate and flip within a small range of environments.

[0017] A second toothed ring is sleeved on the telescopic end of the telescopic shaft and fixedly connected to the telescopic end of the telescopic shaft. And the second toothed ring has the same specification as the first toothed ring.

[0018] Further, the second toothed ring can be meshed with the control gear through the extension of the telescopic shaft.

[0019] Further, the rotor protection cage includes:

[0020] Two mounting rings are respectively rotatably arranged on the outer peripheral walls of the two sleeve pipes. Mounting shafts are arranged on the outer peripheral wall of the mounting ring in an annular array. A restoring component is arranged on the end wall of the mounting ring;

[0021] An arc-shaped anti-collision strip is rotatably connected to two corresponding mounting shafts at both ends. A spring clip is arranged between two adjacent arc-shaped anti-collision strips.

[0022] Furthermore, the spring clip is arranged in a V shape, the bottom end of the spring clip is fixedly connected to the mounting ring, and the two sides of the spring clip are in contact with the side walls of the arc-shaped anti-collision strip.

[0030] 2. When there is a risk of the UAV's fan blades colliding with the outside world, the external impact will first collide with the sphere formed by multiple arc-shaped anti-collision strips and the mounting ring. When the collision occurs, the arc-shaped anti-collision strip is offset by pressure, causing the spring clip to deform, thereby achieving the purpose of unloading force. In addition, the arc-shaped anti-collision strip deflects when subjected to force, causing the arc-shaped anti-collision strip to drive the mounting ring to rotate, and at this time drives the return assembly to rotate, thereby achieving the purpose of further unloading force, thereby realizing the purpose of protecting the flying rotor.

[0045] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustrating and explaining the present invention and are not used to limit the present invention.

[0046] Referring to Figures 1-9 As shown, according to Embodiment 1 of the present invention, a multi-functional emergency rescue multi-rotor unmanned aerial vehicle is provided, including:

[0047] The UAV frame 1 has an accommodation compartment inside. The accommodation compartment is used to store rescue supplies, and an electric control delivery device is arranged inside the accommodation compartment. It can receive control signals from the ground through the control unit built in the UAV to throw out the supplies inside the accommodation compartment, so as to realize the supply delivery to the people in need of rescue. On both sides of the UAV frame 1, there are installation compartments 2. Inside the installation compartments 2, there are a control unit and a power supply unit. The control unit is equivalent to the controller arranged inside the UAV in the prior art, which is used to receive ground operation signals and control each driving component inside the UAV through signals to realize operations such as starting, stopping, accelerating and decelerating of the UAV. The power supply unit is the battery of the UAV in the prior art, which is used to supply power to the UAV. At one end of the installation compartment 2 far away from the UAV frame 1, there are driving frames 3 respectively;

[0048] Connecting shafts 4. There are two connecting shafts 4, which are respectively inserted into the left and right sides of the driving frame 3 and are rotatably connected to the driving frame 3;

[0049] A control motor 5 is fixedly arranged inside the driving frame 3. The control motor 5 controls the rotation of the two connecting shafts 4 through a gear assembly 6 and a linkage assembly 7 arranged inside the driving frame 3. By the cooperation of the control motor 5 and the gear assembly 6, the connecting shafts 4 rotate, and with the arrangement of the linkage assembly 7, when the connecting shafts 4 on both sides rotate, they can rotate in the same direction or rotate relatively, so that the arc-shaped frames 8 connected by the two connecting shafts 4 can flip synchronously in the same direction or synchronously in the opposite direction, so as to realize the change of the flight attitude of the UAV, such as Figure 1 and Figure 3 shown;

[0050] Among them Figure 1 is the structural schematic diagram of the UAV during normal flight. At this time, the UAV can fly freely in an open area;

[0051] Figure 3 is the structural schematic diagram of the rotor flipping. At this time, by the different orientations of the single-side rotors, the thrust angles of each rotor are changed, so that the UAV rotates or flips;

[0052] An arc-shaped frame 8 is fixedly arranged at one end of the connecting shaft 4 far away from the driving frame 3. Inside the arc-shaped frame 8, there is a rotating ring 9. On the outer peripheral wall of the rotating ring 9, there are two coaxial rotating shafts 10. The rotating ring 9 is rotatably connected to both ends of the arc-shaped frame 8 through the rotating shafts 10. And at one end of the arc-shaped frame 8, there is a control component 11 for controlling the rotation of the rotating ring 9. Inside the rotating ring 9, there is an installation rod 12. At a position corresponding to the axis of the rotating ring 9 on the installation rod 12, there is a rotor motor 13. At the top of the rotor motor 13, there is a flight rotor 14. Among them, the installation rod 12 is fixedly connected to the rotating ring 9. Through the control component 11, the rotation of the rotating ring 9 can be controlled to realize the change of the attitude of the UAV, such as Figure 2As shown Figure 2 Figure 1 is a schematic diagram of the vertical flight state of the drone. At this time, the drone can fly in narrow positions, such as the gaps between houses and the gaps between trees. Both ends of the mounting rod 12 are provided with sleeves 15, and a rotor protection cage 16 is jointly arranged on the outer peripheral walls of the two sleeves 15. The rotor protection cage 16 is used to protect the flight rotor 14.

[0053] In a further preferred embodiment of the present invention, as Figure 7 and Figure 8 shown, the linkage assembly 7 includes:[[]]END]]

[0054] A bushing 71 is arranged inside the driving frame 3 and is fixedly connected to the left connecting shaft 4. A sliding cavity 72 is arranged inside the bushing 71, and a retaining ring 73 is arranged inside the sliding cavity 72.

[0055] A telescopic shaft 74 is arranged inside the driving frame 3 and is fixedly connected to the right connecting shaft 4. The telescopic shaft 74 includes an outer sleeve part and a telescopic end. An electric push rod is arranged inside the outer sleeve part. The electric push rod is electrically connected to the control unit and can receive information from the ground through the control unit to control the electric push rod to expand and contract, so as to achieve the effect of controlling the telescopic shaft 74 to expand and contract. The outer sleeve part is fixedly connected to the connecting shaft 4 on the right side of the driving frame 3, and a sliding rod 75 is fixedly connected to the end of the telescopic shaft 74.

[0056] A sliding rod 75, one end of the sliding rod 75 is inserted into the sliding cavity 72, and the other end of the sliding rod 75 is fixedly connected to the telescopic end of the telescopic shaft 74. A convex ring 76 is arranged at the end of the sliding rod 75 inserted into the sliding cavity 72. When the telescopic shaft 74 is in the extended state, the convex ring 76 arranged at the end of the sliding rod 75 does not contact the retaining ring 73. At this time, the bushing 71 and the telescopic shaft 74 are rotatably connected. When the control motor 5 drives the telescopic shaft 74 and the bushing 71 to rotate through the gear assembly 6, the bushing 71 and the telescopic shaft 74 can rotate relative to each other, so as to achieve the purpose of simultaneously and reversely flipping the arc-shaped frames 8 on the same side, as Figure 3 shown

[0057] When the telescopic shaft 74 is in the contracted state, the convex ring 76 is in close contact with the retaining ring 73, so that the telescopic shaft 74 and the bushing 71 form a fixed connection. When the control motor 5 and the gear assembly 6 drive the telescopic shaft 74 and the bushing 71 to rotate, the bushing 71 and the telescopic shaft 74 can rotate synchronously and in the same direction.

[0058] In a further preferred embodiment of the present invention, as Figure 7 and Figure 8As shown, a limiting tooth 77 is provided on the side wall of the retaining ring 73, and a fixing tooth 78 is provided on the side of the convex ring 76 facing the retaining ring 73. The fixing tooth 78 and the limiting tooth 77 can be engaged with each other. Both the limiting tooth 77 and the fixing tooth 78 are triangular teeth. When the convex ring 76 contacts the retaining ring 73, the limiting tooth 77 and the fixing tooth 78 can interact through the tooth surfaces provided on the inclined surfaces to form an engagement. Thus, when the telescopic shaft 74 expands and contracts to make the convex ring 76 contact the retaining ring 73, the purpose of fixing the convex ring 76 and the retaining ring 73 is achieved, so that the convex ring 76 and the retaining ring 73 can move synchronously.

[0059] In a further preferred embodiment of the present invention, as Figure 7 and Figure 8 shown, the gear assembly 6 includes:

[0060] A control gear 61, which is fixedly connected to the motor shaft of the control motor 5. The control gear 61 is fixedly connected to the motor shaft of the control motor 5 by means of a key connection, so that the control gear 61 can rotate following the rotation of the motor shaft;

[0061] A first tooth ring 62, which is sleeved on the outer peripheral wall of the shaft sleeve 71 and is fixedly connected to the shaft sleeve 71. The first tooth ring 62 is meshed with the control gear 61. The first tooth ring 62 is fixedly connected to the shaft sleeve 71, and the first tooth ring 62 is always meshed with the control gear 61. When the control gear 61 rotates, the shaft sleeve 71 can be driven to rotate through the first tooth ring 62, and then the connecting shaft 4 on the left side of the driving frame 3 is driven to rotate;

[0062] A second tooth ring 63, which is sleeved on the telescopic end of the telescopic shaft 74 and is fixedly connected to the telescopic end of the telescopic shaft 74. The second tooth ring 63 has the same specification as the first tooth ring 62. Since the second tooth ring 63 has the same specification as the first tooth ring 62, the second tooth ring 63 can be meshed with the control gear 61;

[0063] The second tooth ring 63 can be meshed with the control gear 61 through the extension of the telescopic shaft 74.

[0064] As Figure 7 and Figure 8 shown, when the telescopic shaft 74 is in the extended state, the telescopic end pushes the sliding rod 75 to move towards the sliding cavity 72 inside the shaft sleeve 71. At this time, the convex ring 76 and the retaining ring 73 do not contact, and the second tooth ring 63 follows the telescopic end to move and gradually meshes with the control gear 61. Since the shaft sleeve 71 and the telescopic shaft 74 are in a state where they can rotate relative to each other at this time, when the control gear 61 rotates, the first tooth ring 62 and the second tooth ring 63 on both sides of it can be driven to move synchronously in the opposite direction, and thus the effect of adjusting the angles of the arc-shaped frames 8 on both sides is achieved.

[0065] In a further preferred embodiment of the present invention, asFigure 6 and Figure 9 As shown:

[0066] like Figure 6 As shown, the rotor protection cage 16 includes:

[0067] Mounting rings 161, two mounting rings 161 are provided and are rotatably arranged on the outer peripheral walls of the two sleeves 15 respectively. The outer peripheral walls of the mounting rings 161 are provided with mounting shafts in an annular array, and the end walls of the mounting rings 161 are provided with a return assembly 162;

[0068] The arc-shaped anti-collision strip 163 has two corresponding mounting shafts at both ends thereof rotatably connected, and a spring clip 164 is provided between two adjacent arc-shaped anti-collision strips 163;

[0069] When the fan blades of the drone are at risk of colliding with the outside world, the outside impact will first collide with the sphere formed by the multiple arc-shaped anti-collision strips 163 and the mounting ring 161. When the collision occurs, the arc-shaped anti-collision strip 163 is deflected by the pressure, causing the spring clip 164 to deform, thereby achieving the purpose of unloading the force. In addition, the arc-shaped anti-collision strip 163 is deflected when subjected to force, causing the arc-shaped anti-collision strip 163 to drive the mounting ring 161 to rotate, and at this time, the return assembly 162 is driven to rotate, thereby achieving the purpose of further unloading the force.

[0070] On the other hand, after the impact force of the collision between the drone and the object is released, the recovery component 162 and the spring clip 164 will rebound to restore the shape of the rotor protection cage 16 to protect the flying rotor 14.

[0071] In a further preferred embodiment of the present invention, Figure 6 As shown, the gear assembly 6 includes: the spring clip 164, the spring clip 164 is arranged in a V shape, the bottom end of the spring clip 164 is fixedly connected to the mounting ring 161, and the two sides of the spring clip 164 are in contact with the side walls of the arc-shaped anti-collision strip 163, as shown in FIG. Figure 6 As shown, the spring clip 164 is arranged in a V shape, and the two sides are in contact with the side walls of the two adjacent arc-shaped anti-collision strips 163. Therefore, in normal state, the arc-shaped anti-collision strip 163 can be formed into a spherical shape by the supporting force of the spring clip 164, as shown in FIG. Figure 6 As shown, when the arc-shaped anti-collision strip 163 is deflected due to impact, it can be reset by the spring clips 164 on both sides to achieve force unloading and protect the flight rotor 14 again.

[0072] In a further preferred embodiment of the present invention, Figure 9 As shown, the reply component 162 includes:

[0073] Fixing cylinder 1621 is fixedly connected to one end of the mounting ring 161. Inside the fixing cylinder 1621, there is a rotating torsion spring 1622. At both ends of the rotating torsion spring 1622, there are insertion plates 1623. On the cylinder wall of the fixing cylinder 1621 and the outer wall of the sleeve 15, there are slots respectively that cooperate with the insertion plates 1623. When the arc-shaped anti-collision strip 163 is hit and drives the mounting ring 161 to rotate, it will drive the fixing cylinder 1621 fixedly connected to the mounting ring 161 to rotate. Since both ends of the rotating torsion spring 1622 are connected to the fixing cylinder 1621 and the sleeve 15 respectively, when the fixing cylinder 1621 rotates, it will twist the rotating torsion spring 1622, causing the rotating torsion spring 1622 to store energy and reducing the impact force generated by the collision. After the collision, the rotating torsion spring 1622 resets to facilitate the rotor protection cage 16 to cope with the next collision.

[0074] In a further preferred embodiment of the present invention, as Figure 5 shown, the control assembly 11 includes:

[0075] A servo motor 111 is fixedly arranged at one end of the arc-shaped frame 8, and a driving spur gear 112 is arranged at one end of the servo motor 111;

[0076] A linkage gear ring 113 is fixedly connected to the outer peripheral wall of one end of the rotating shaft 10, and the linkage gear ring 113 meshes with the driving spur gear 112;

[0077] As Figure 5 shown, the servo motor 111 cooperates with the driving spur gear 112 to drive the linkage gear ring 113 to rotate, thereby controlling the rotation of the rotating shaft 10, so as to change the angle of the rotating ring 9 and make the drone form Figure 2 a neutral flight state.

[0078] The implementation principle of the above embodiment is: by controlling the motor 5 and the gear assembly 6 to drive the connecting shaft 4 to rotate, and cooperating with the setting of the linkage assembly 7, when the two connecting shafts 4 rotate, they can rotate in the same direction or relatively rotate, so that the arc-shaped frames 8 connected by the two connecting shafts 4 can flip synchronously in the same direction or synchronously in the opposite direction, so as to change the flight attitude of the drone, make the drone change between the normal state and the state of rotor deflection, and enable the drone to fly freely or rotate and flip in a small range in an open environment;

[0079] Through the control assembly 11, the rotation of the rotating ring 9 can be controlled to change the attitude of the drone, changing the drone from the normal flight state to the vertical flight state of the drone. At this time, the drone can fly in narrow positions, such as the gaps between houses and the gaps between trees.

[0080] Those skilled in the art can easily understand that, on the premise of no conflict, the above advantageous ways can be freely combined and superimposed.

[0081] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention. The above is only the preferred implementation manner of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and variations can still be made, and these improvements and variations should also be regarded as within the protection scope of the present invention.
