Description

Technical Field

[0001] The present invention relates to the technical field of drones, and particularly to a drone wing that is convenient for getting rid of roadblocks and an operation method thereof. Background Art

[0002] An unmanned aerial vehicle, abbreviated as "drone", is an unpiloted aircraft controlled by radio remote control equipment and a self - contained program control device. In fact, drones are a general term for unpiloted aircraft vehicles. From a technical perspective, they can be classified into: unmanned helicopters, unmanned fixed - wing aircraft, unmanned multi - rotor aircraft, unmanned airships, and unmanned parafoil aircraft.

[0003] With the development of technology, the application of multi - rotor aircraft is becoming more and more common, and the number of drone enthusiasts is also increasing. During the process of controlling a drone, special attention should be paid to air resistance. Once the air flow velocity is relatively large, the drone is very likely to get out of control and finally get stuck in a tree. When the position is relatively low, the operator can make the drone get out of trouble by shaking the tree branches. However, once the drone is stuck in a higher tree, the operator can only be helpless. Moreover, when trying to get the drone out of trouble by force, it will cause damage to the drone. At present, the existing drone technology does not involve the technology of getting a drone out of trouble.

[0004] Therefore, it is necessary to improve the wings of drones to facilitate the drones to get rid of roadblocks. Summary of the Invention

[0005] In order to solve the above - mentioned technical problems existing in the existing drones, the present invention provides a drone wing that is convenient for getting rid of roadblocks and an operation method thereof, which has the characteristics of diverse ways of getting out of trouble and better getting - out - of - trouble effects.

[0006] The first technical solution of the present invention: a drone wing that is easy to get rid of roadblocks, including a drone wing; one end of the drone wing is connected to a motor brake through a wing telescopic rod; the motor brake includes a brake chamber and a motor chamber connected to the brake chamber, the interior of the motor chamber is connected to a drive motor through a drive motor telescopic rod, and a follower is provided on one side of the drive motor; the follower includes a first driven tooth and a second driven tooth; the first drive tooth on the drive motor is meshed and connected with the first driven tooth, and the first drive tooth is used to rotate the first driven tooth; when the drive motor telescopic rod is braked downward, the second drive tooth on the drive motor is meshed and connected with the second driven tooth through a speed reducer, and the speed reducer is used to rotate the second driven tooth; the lower part of the follower is connected to a blade connector through a fixed member telescopic rod, both sides of the blade connector are connected to wing blades, and the upper side of the blade connector is provided with a cylindrical extrusion ring, and the cylindrical extrusion ring is used to rotate the blade connector downward. The present invention can shake and retract the wings of the drone by arranging wing shaking parts and wing telescopic rods on the wings of the drone; when the drone is driven normally, the first driving tooth on the driving motor is meshed and connected with the first driven tooth on the driven part, and then the rotation of the first driving tooth can drive the rotation of the first driven tooth, and the first driven tooth can further drive the rapid rotation of the blade connecting part to realize the flight of the drone; when the drone encounters a roadblock and needs to get rid of it, the driving motor is pushed downward under the braking of the telescopic rod of the driving motor, so that the first driving tooth is staggered with the first driven tooth, and then the second driving tooth under the first driving tooth slides downward, and is meshed and connected with the speed reducer during the downward sliding of the second driving tooth, and the second driven tooth on the driven part is driven to rotate slowly under the deceleration of the speed reducer, so that the drone can get rid of it under slow operation, and the wing blades can be The slow operation of the blade can prevent the blades of the drone from being damaged, and can also help the drone get out of trouble. After getting out of trouble, the driving motor is lifted upward by the telescopic rod of the driving motor, so that the first driving tooth on the driving motor is re-engaged with the first driven tooth, providing a new round of power to the driven member; the lower part of the driven member of the present invention is connected with a blade connecting member through the telescopic rod of the fixing member, and wing blades are connected to both sides of the blade connecting member. The rotation of the blade connecting member can be driven by the transmission of the driven member, thereby promoting the movement of the drone, and a cylindrical extrusion ring is provided on the upper side of the blade connecting member, which is used to rotate the blade connecting member downward. Furthermore, unlike the traditional blade method, the wing blade is arranged at the bottom of the motor brake, and the wing of the drone can play a certain protective role on the wing blade, effectively protecting the wing blade and improving the service life of the wing blade.

[0007] Preferably, both the first driving gear and the second driving gear are fixedly arranged on the output end of the driving motor. The second driving gear is arranged below the first driving gear. The first driving gear and the first driven gear are on the same horizontal axis. When the telescopic rod of the driving motor brakes downward, the second driving gear and the speed reducer are on the same horizontal axis.

[0008] The speed reducer is rotatably arranged inside the transmission chamber through a speed reduction wheel transmission rod. The speed reducer includes a first speed reduction wheel and a second speed reduction wheel. The second speed reduction wheel is meshed and connected with the second driven gear, and the second speed reduction wheel is used to rotate the second driven gear. When the second driving gear brakes downward, the second driving gear is rotatably connected with the first speed reduction wheel. The speed reducer can greatly reduce the speed transmitted by the driving motor, so that the blades can rotate slowly, which is beneficial for the drone to get rid of roadblocks.

[0009] Preferably, the driven member is rotatably arranged inside the brake chamber through a driven shaft. The blade connecting member includes a fixing plate and a blade connecting plate. The bottom of the telescopic rod of the fixing member is fixedly connected with the fixing plate. The blade connecting plate is rotatably arranged at both ends of the fixing plate. A blade mounting hole is formed at one end of the blade connecting plate away from the fixing plate, and the blade mounting hole is fixedly connected with the wing blade. A first spring fixing member is fixedly arranged at the upper end of the blade connecting plate, and a second spring fixing member corresponding to the first spring fixing member is arranged on the fixing plate. A second return spring is fixedly arranged between the first spring fixing member and the second spring fixing member. A rubber rod is arranged inside the second return spring. One end of the rubber rod is fixedly connected with the second spring fixing member, and the other end of the rubber rod contacts the first spring fixing member. The rubber rod limits the second return spring. The driven member is fixedly connected with the fixing plate, and at the same time, the blade connecting plate is rotatably arranged at both ends of the fixing plate. Therefore, the blade connecting plate can rotate downward around the fixing plate to achieve the purpose of retracting the wing blade. The blade mounting head at one end of the wing blade is fixedly connected with the blade connecting plate by screws, which improves the structural strength of the wing blade and greatly extends the service life of the used wing blade. The first spring fixing member arranged on the blade connecting plate and the second spring fixing member arranged on the fixing plate are tightened by the second return spring. Therefore, it can prevent the wing blade from rotating without braking, avoiding damage to the flight path of the drone. At the same time, a rubber rod is also arranged inside the second return spring. One end of the rubber rod is fixedly connected with the second spring fixing member, and the other end of the rubber rod contacts the first spring fixing member. That is to say, the other end of the rubber rod only contacts the first spring fixing member and is not fixedly connected. In this case, the wing blade will not rotate upward, so the wing blade will not be stuck, improving the operating efficiency of the wing blade.

[0010] Preferably, a fixed bottom plate is connected to the bottom of the braking chamber. A bottom plate through hole and a plurality of pressing member sliding holes that are centrosymmetric about the bottom plate through hole are formed in the middle of the fixed bottom plate.

[0011] The bottom of the cylindrical pressing ring is connected with a pressing ring through a pressing ring guiding column. The fixing member telescopic rod passes through the pressing ring through hole. The upper end of the fixing plate passes through the bottom plate through hole and is fixedly connected to the output end of the fixing member telescopic rod. A first return spring is arranged between the cylindrical pressing ring and the fixed bottom plate. The upper end of the first return spring is fixedly connected to the bottom surface of the cylindrical pressing ring, and the lower end of the first return spring is fixedly connected to the upper end surface of the fixed bottom plate. The cylindrical pressing ring is arranged inside the motor braking member. The pressing ring guiding column on the cylindrical pressing ring is slidably arranged inside the pressing member sliding hole. Therefore, the cylindrical pressing ring can slide up and down on the fixed bottom plate. Further, the cylindrical pressing ring is fixedly connected to the fixed bottom plate through the first return spring. That is to say, when the cylindrical pressing ring does not brake downward, under the action of the second return spring, the pressing ring below the cylindrical pressing ring is separated from the wing blade, avoiding the pressing of the wing blade by the pressing ring and causing the wing blade to be stuck.

[0012] The pressing ring guiding column passes through the pressing member sliding hole, and the pressing ring guiding column is vertically slidably arranged inside the pressing member sliding hole. The cylindrical pressing ring is arranged inside the motor braking member. Among them, when the driving motor telescopic rod brakes downward, the output end of the driving motor abuts against the upper side surface of the cylindrical pressing ring. When the driving motor brakes downward, the bottom of the output end of the driving motor presses the cylindrical pressing ring. The pressing ring guiding column slides inside the pressing member sliding hole, and the pressing ring presses the blade connecting plate, causing the wing blade to rotate downward.

[0013] The extrusion ring is arranged outside the electric motor brake member, and the extrusion ring does not contact the blade connecting member. Wherein, when the driving motor telescopic rod brakes downward, the extrusion ring abuts against the blade connecting plate, and the angle of downward rotation of the blade connecting plate is 0-90°. When the driving motor brakes downward, the output end of the driving motor extrudes the upper side of the cylindrical extrusion ring, and the extrusion ring guide column on the cylindrical extrusion ring slides inside the extrusion member sliding hole. Therefore, the extrusion ring extrudes the blade connecting plate downward under the action of the extrusion member, and the blade connecting plate rotates downward under extrusion, and the rotation angle is 90°. In this way, the wing blades will rotate downward, and the two wing blades will fit together to avoid damage to the wing blades. At the same time, the second return spring between the first spring fixing member and the second spring fixing member deforms under the tension. Once the driving motor brakes upward, the second return spring will return to the initial state, and the wing blades can operate normally. Further, when the driving motor brakes downward, the second driving tooth on the driving motor is meshed with the second driven tooth, that is, slow rotation can still occur when the wing blades are closed, so as to effectively get rid of roadblocks.

[0014] Preferably, a counterweight connecting block is arranged between the first driven tooth and the second driven tooth. The counterweight connecting block is fixedly arranged on the driven shaft. A counterweight is arranged on the counterweight connecting block, and a counterweight assembly hole matching the counterweight connecting block is opened in the middle of the counterweight. Adding a counterweight can make the UAV land slowly under the action of inertia, and effectively ensure the safety of the UAV and improve the service life of the UAV even in the case of a large separation.

[0015] Preferably, a blade mounting head is fixedly arranged at one end of the wing blade. The blade mounting head is of a U-shaped structure. The blade mounting head is sleeved at one end of the blade connecting plate and is fixedly connected by screws to improve the stability of the wing blade mounting. The wing blade includes a main blade and a sub-blade. The upper side of the sub-blade is lower than the upper side of the main blade. A reinforcing strip is fixedly arranged inside the main blade. The reinforcing strip is made of high-speed steel. A counterweight magnetic sheet is arranged at one end of the main blade away from the blade mounting head, and the counterweight magnetic sheet is arranged inside the wing blade. The wing blade plays a crucial role in the UAV. The strength of the wing blade determines the service life of the UAV. Therefore, arranging a reinforcing strip in the wing blade can further improve the structural strength of the wing blade and the service life of the UAV. The counterweight magnetic sheet can fit the two wing blades together, and can effectively protect the wing blades when the UAV needs to get out of trouble.

[0016] Preferably, the drone wing comprises a wing shaking member, a wing telescopic rod and a connecting rod; a hinge connecting member is fixedly arranged between the connecting rod and the wing shaking member, one end of the hinge connecting member is fixedly connected to the wing shaking member, and the other end of the hinge connecting member is fixedly connected to the connecting rod, and the rotation angle range of the drone wing is 0 to 90°;

[0017] A rubber pad is provided between the connecting rod and the wing shaking member, one end of the rubber pad is fixedly connected to the connecting rod, and the other end of the rubber pad is against the connecting rod. The end of the connecting rod away from the wing shaking member is connected to an assembly plate, and the assembly plate is connected to the drone through bolts. The rotation angle of the hinge connection is 0 to 90 degrees, so the wing shaking member can be used to rotate the drone wing through the hinge connection. When the drone needs to be started, the drone wing can be rotated clockwise around the hinge connection to extend the drone wing, increase the area of ​​the drone wing extending in the air, and greatly improve the efficiency of the drone lifting; the assembly plate on the connecting rod is collectively fixedly connected to the drone and fixedly connected by screws, so that the strength of the structure is greatly improved, and a rubber pad is fixedly provided on the contact surface between the connecting rod and the wing telescopic rod. The rubber pad can play a certain buffering role to prevent the drone wing from being damaged and improve the service life of the hinge connection and the drone wing.

[0018] Preferably, a vibration motor is fixedly installed inside the wing shaking part, and an anisotropic cam is installed at the output end of the vibration motor, and the anisotropic cam is used to shake the wing of the UAV. A heat sink is fixedly installed on the wing shaking part, and the inner side surface of the heat sink extends to the inside of the wing shaking part, and the outer side surface of the heat sink extends to the outside of the wing shaking part, and the heat sink is used to dissipate the heat of the vibration motor. A vibration motor is fixedly installed inside the wing shaking member on the wing of the drone, and a heterosexual cam is installed at the output end of the vibration motor. Therefore, when the vibration motor rotates, the heterosexual cam will rotate unbalancedly, which will drive the shaking of the entire wing shaking member, and then drive the shaking of the entire drone wing. When the drone is hung on a tree branch, the center of gravity of the drone wing can be frequently changed through the vibration of the drone wing, and at the same time, inertia can be used to get the drone out of trouble. The structure is simple and easy to use. The two sides of the heat sink pass through the wing shaking member, so the heat generated inside the wing shaking member can be transferred to the outside, preventing the temperature inside the wing shaking member from being too high and affecting the normal use of the vibration motor, thereby improving the service life of the vibration motor.

[0019] Preferably, a wing telescopic rod is connected to one end of the wing shaking member away from the wing shaking member, and the output end of the telescopic rod of the wing telescopic rod is fixedly connected to the brake compartment, and the wing telescopic rod is used to horizontally push the motor brake. A wing telescopic rod is connected between the wing shaking member and the motor brake, and the output end of the wing telescopic rod is fixedly connected to the motor brake. Therefore, the motor brake can be telescoped back and forth through the wing telescopic rod. When the wing of the drone is stuck, the center of gravity of the drone or the center of gravity of the motor brake can be changed by extending the length of the output end of the telescopic rod, and the motor brake on the wing of the drone can be freed under the action of gravity. Therefore, the purpose of getting the drone out of the roadblock can be achieved by telescoping the motor brake.

[0020] The second technical solution of the present invention is a method for operating the wings of a drone that is convenient for getting rid of roadblocks, comprising the following steps:

[0021] (S01) Blade closing and getting rid of

[0022] Start the telescopic rod of the drive motor to push the drive motor downward, the output end of the drive motor abuts against the upper side of the cylindrical extrusion ring, the extrusion ring guide column on the cylindrical extrusion ring slides inside the sliding hole of the extrusion piece of the fixed bottom plate, so that the lower end surface of the extrusion ring abuts against the blade connecting plate, and the blade connecting plate rotates downward under the action of the extrusion ring, and the rotation angle is 0 to 90 degrees. When the wing blades of the drone are stuck, the wing blades on the blade connecting plate can be rotated to get rid of the roadblock;

[0023] (S02) Blade closing and rotation to get rid of

[0024] If the UAV fails to get rid of the roadblock after starting the telescopic rod of the driving motor, the driving motor is started, and under the action of the telescopic rod of the driving motor, the second driving tooth drives the rotation of the reduction member, and the blade connecting member is driven to rotate slowly through the reduction member, so that the wing blades can move slowly in the closed state, so that the UAV can get rid of the roadblock;

[0025] (S03) Support arm pushes away

[0026] When the drone encounters a roadblock, the wing telescopic rod on the drone's wing is activated to change the length of the drone's wing, thereby changing the center of gravity of the drone and achieving the purpose of getting rid of the roadblock;

[0027] (S04) Get rid of vibration

[0028] Start the vibration motor inside the wing shaking part, and the wings of the drone will shake violently under the action of the anisotropic cam. While changing the center of gravity, inertia is used to make the drone get rid of obstacles.

[0029] A variety of escape methods can be used individually or in combination, which can greatly improve the efficiency of UAV escape and extend the service life of UAV.

[0030] The present invention has the following beneficial effects:

[0031] (1) By setting the rotation angle of the hinge connection to 0-90°, the wing shaking part can rotate the drone wing through the hinge connection. When the drone needs to be started, the drone wing 1 can be rotated clockwise around the hinge connection to extend the drone wing, thereby increasing the area of ​​the drone wing extending in the air and greatly improving the efficiency of the drone lifting. A rubber pad is fixedly provided on the contact surface between the connecting rod and the wing telescopic rod. The rubber pad can play a certain buffering role, prevent the drone wing from being damaged, and increase the service life of the hinge connection and the drone wing;

[0032] (2) By setting a wing shaking piece on the wing of the drone, a cam with an opposite sex is set at the output end of the vibration motor. Therefore, when the vibration motor rotates, the cam with an opposite sex will rotate unbalancedly, which will drive the shaking of the entire wing shaking piece, and then drive the shaking of the entire drone wing. When the drone is hung on a tree branch, the center of gravity of the drone wing can be frequently changed through the vibration of the drone wing, and the drone can be freed by using inertia;

[0033] (3) By setting a wing telescopic rod between the wing shaking part and the motor brake part, the output end of the wing telescopic rod is fixedly connected to the motor brake part, so that the motor brake part can be telescoped back and forth through the wing telescopic rod. When the wing of the UAV is stuck, the center of gravity of the UAV or the center of gravity of the motor brake part can be changed by extending the length of the output end of the telescopic rod, and the motor brake part on the wing of the UAV can be freed under the action of gravity. Therefore, the purpose of freeing the UAV from the roadblock can be achieved by telescoping the motor brake part;

[0034] (4) When the UAV encounters an obstacle and needs to get rid of it, the drive motor is pushed downward under the brake of the drive motor telescopic rod, so that the first drive tooth is offset from the first driven tooth, and then the second drive tooth below the first drive tooth slides downward. During the downward sliding process of the second drive tooth, it meshes with the reduction member, and the second driven tooth on the driven member is driven to rotate slowly under the deceleration of the reduction member. Therefore, the UAV can get rid of it under slow operation. The slow operation of the wing blades can prevent the blades of the UAV from being damaged, and can also help the UAV get out of trouble. After getting out of trouble, the drive motor is lifted upward by the drive motor telescopic rod, so that the first drive tooth on the drive motor meshes with the first driven tooth again, providing a new round of power to the driven member;

[0035] (5) When the drive motor brakes downward, the output end of the drive motor presses against the upper side of the cylindrical extrusion ring, and the extrusion ring guide posts on the cylindrical extrusion ring slide inside the extrusion part sliding holes. Therefore, under this action, the extrusion ring presses downward on the blade connecting plate, and the blade connecting plate rotates downward under the extrusion, and the rotation angle is 90°. In this way, the wing blades will rotate downward, and the two wing blades will fit together to avoid damage to the wing blades. The second return spring between the first spring fixing part and the second spring fixing part deforms under the tensile force. Once the drive motor brakes upward, the second return spring will return to its initial state, and the wing blades can operate normally;

[0036] When the drive motor brakes downward, the second drive gear on the drive motor meshes with the second driven gear, that is, it can still rotate slowly when the wing blades are closed, so as to effectively get rid of roadblocks. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0050] The present invention will be further described below in conjunction with embodiments and the drawings, but it shall not be used as a basis for limiting the present invention.

[0051] As Figure 1A drone wing that is convenient for getting rid of roadblocks is shown, including the drone wing 1. One end of the drone wing 1 is connected to an electric motor braking member 2 through a wing telescopic rod 102. The electric motor braking member 2 includes a braking chamber 202 and a motor chamber 201 that is threadedly connected to the braking chamber 202. In the present invention, by providing a wing shaking member 101 and a wing telescopic rod 102 on the drone wing 1, the drone wing 1 can be shaken and telescoped. The drone wing 1 includes a wing shaking member 101, a wing telescopic rod 102, and a connecting rod 104. A hinge connecting member 18 is fixedly provided between the connecting rod 104 and the wing shaking member 101. One end of the hinge connecting member 18 is fixedly connected to the wing shaking member 101, and the other end of the hinge connecting member 18 is fixedly connected to the connecting rod 104. The rotation angle range of the drone wing 1 is 0 to 90°, and the rotation angle of the hinge connecting member 18 is 0 to 90°. Therefore, the wing shaking member 101 can rotate the drone wing 1 through the hinge connecting member 18. When starting the drone, the drone wing 1 can be rotated clockwise around the hinge connecting member 18 to extend the drone wing 1, increasing the area of the drone wing 1 extended in the air and greatly improving the lifting efficiency of the drone.

[0052] A rubber pad 20 is provided between the connecting rod 104 and the wing shaking member 101. One end of the rubber pad 20 is fixedly connected to the connecting rod 104, and the other end of the rubber pad 20 abuts against the connecting rod 104. The end of the connecting rod 104 away from the wing shaking member 101 is connected to an assembly plate 105. The assembly plate 105 is bolted to the drone. By fixedly connecting the assembly plate 105 on the connecting rod 104 to the body of the drone through screws, the strength of the structure is greatly improved. Moreover, a rubber pad 20 is fixedly provided on the contact surface between the connecting rod 104 and the wing telescopic rod 102. The rubber pad 20 can play a certain buffering role to prevent the drone wing 1 from being damaged and improve the service life of the hinge connecting member 18 and the drone wing 1.

[0053] As Figure 11The wing of a UAV that is easy to get rid of roadblocks is shown in the figure. A vibration motor 11 is fixedly arranged inside the wing shaking member 101. A heterosexual cam 12 is arranged at the output end of the vibration motor 11. The heterosexual cam 12 is used to shake the UAV wing 1. The vibration motor 11 is fixedly arranged inside the wing shaking member 101 on the UAV wing 1, and the heterosexual cam 12 is arranged at the output end of the vibration motor 11. Therefore, under the rotation of the vibration motor 11, the heterosexual cam 12 will rotate unbalancedly, which will drive the shaking of the entire wing shaking member 101, and then drive the shaking of the entire UAV wing 1. When the UAV is hung on a tree branch, the vibration of the UAV wing 1 can be used to The wing shaking member 101 is fixed with a heat sink 19, and the inner side of the heat sink 19 extends to the inside of the wing shaking member 101, and the outer side of the heat sink 19 extends to the outside of the wing shaking member 101. The heat sink 19 is used to dissipate heat for the vibration motor 11. The two side surfaces of the heat sink 19 penetrate the wing shaking member 101, so that the heat generated inside the wing shaking member 101 can be transferred to the outside, so as to prevent the temperature inside the wing shaking member 101 from being too high and affecting the normal use of the vibration motor 11, thereby improving the service life of the vibration motor 11.

[0054] At the same time, the end of the wing shaking member 101 away from the wing shaking member 101 is connected to the wing telescopic rod 102, and the telescopic rod output end 103 of the wing telescopic rod 102 is fixedly connected to the brake compartment 202. The wing telescopic rod 102 is used to horizontally push the motor brake 2. The wing telescopic rod 102 is connected between the wing shaking member 101 and the motor brake 2, and the output end of the wing telescopic rod 102 is fixedly connected to the motor brake 2. Therefore, the motor brake 2 can be telescoped back and forth through the wing telescopic rod 102. When the UAV wing 1 is stuck, the center of gravity of the UAV or the center of gravity of the motor brake 2 can be changed by extending the length of the telescopic rod output end 103, and the motor brake 2 on the UAV wing 1 can be freed under the action of gravity. Therefore, the purpose of making the UAV get rid of the roadblock can be achieved by telescoping the motor brake 2.

[0055] like Figure 2 , Figure 3 and Figure 4 The wing of a UAV that is convenient for getting rid of roadblocks is shown, and a driving motor 4 connected by a driving motor telescopic rod 10 is arranged inside the motor compartment 201, and a follower 5 is arranged on one side of the driving motor 4, and the follower 5 includes a first driven tooth 501 and a second driven tooth 502;

[0056] Among them, the first driving tooth 401 on the driving motor 4 is meshed and connected with the first driven tooth 501, and the first driving tooth 401 is used to rotate the first driven tooth 501. When the driving motor telescopic rod 10 is braked downward, the second driving tooth 402 on the driving motor 4 is meshed and connected with the second driven tooth 502 through the reduction member 7, and the reduction member 7 is used to rotate the second driven tooth 502. The first driving tooth 401 and the second driving tooth 402 are both fixedly arranged on the output end of the driving motor 4, and the second driving tooth 402 is arranged below the first driving tooth 401. Among them, the first driving tooth 401 and the first driven tooth 501 are on the same horizontal axis. When the driving motor telescopic rod 10 is braked downward, the second driving tooth 402 and the reduction member 7 are on the same horizontal axis.

[0057] When the drone is driving normally, Figure 4 As shown, the first driving tooth 401 on the driving motor 4 is meshedly connected with the first driven tooth 501 on the driven member 5, and the rotation of the first driving tooth 401 can drive the rotation of the first driven tooth 501, and the first driven tooth 501 can further drive the blade connector 8 to rotate quickly, thereby realizing the flight of the UAV.

[0058] When the drone encounters a roadblock and needs to get rid of it, Figure 3 As shown, the drive motor 4 is pushed downward under the braking of the drive motor telescopic rod 10, so that the first drive tooth 401 is staggered with the first driven tooth 501, and then the second drive tooth 402 below the first drive tooth 401 slides downward, and is meshed and connected with the reduction member 7 during the downward sliding of the second drive tooth 402, and the second driven tooth 502 on the follower 5 is driven to rotate slowly under the deceleration of the reduction member 7, so that the drone can be freed under slow operation, and the slow operation of the wing blades 3 can prevent the blades of the drone from being damaged, and can also help the drone get out of trouble. After getting out of trouble, the drive motor 4 is lifted upward through the drive motor telescopic rod 10, so that the first drive tooth 401 on the drive motor 4 is meshed with the first driven tooth 501 again, providing a new round of power to the follower 5.

[0059] Furthermore, the reduction member 7 is rotatably arranged inside the transmission compartment 203 through the reduction wheel transmission rod 702. The reduction member 7 includes a first reduction wheel 701 and a second reduction wheel 703. The second reduction wheel 703 is meshed and connected with the second driven tooth 502. The second reduction wheel 703 is used to rotate the second driven tooth 502. When the second drive tooth 402 brakes downward, the second drive tooth 402 is rotationally connected with the first reduction wheel 701. The second drive tooth 402 is rotationally connected with the first reduction wheel 701. The reduction member 7 can significantly reduce the transmission rate of the drive motor 4, thereby allowing the blades to rotate slowly, which is beneficial for the drone to get rid of roadblocks.

[0060] like Figure 6 andFigure 7 A drone wing that is convenient for getting rid of roadblocks is shown. A blade connecting member 8 is connected below a driven member 5 through a fixing member telescopic rod 503. Wing blades 3 are connected to both sides of the blade connecting member 8. The rotation of the blade connecting member 8 can be driven by the transfer of the driven member 5, thereby promoting the movement of the drone. Moreover, a cylindrical extrusion ring 9 is provided on the upper side of the blade connecting member 8, and the cylindrical extrusion ring 9 is used to rotate the blade connecting member 8 downward. Further, different from the traditional blade method, the wing blade 3 is arranged at the bottom of the electric motor brake member 2. The drone wing 1 can play a certain protective role for the wing blade 3, effectively protecting the wing blade 3 and improving the service life of the wing blade 3.

[0061] The driven member 5 is rotatably arranged inside the brake chamber 202 through a driven shaft 504. The blade connecting member 8 includes a fixing plate 801 and a blade connecting plate 802. The bottom of the fixing member telescopic rod 503 is fixedly connected to the fixing plate 801. The blade connecting plate 802 is rotatably connected to both ends of the fixing plate 801 by rivets. A blade mounting hole 803 is opened at one end of the blade connecting plate 802 away from the fixing plate 801, and the blade mounting hole 803 is fixedly connected to the wing blade 3. The driven member 5 is fixedly connected to the fixing plate 801. At the same time, the blade connecting plate 802 is rotatably arranged at both ends of the fixing plate 801. Therefore, the blade connecting plate 802 can rotate downward around the fixing plate 801 to achieve the purpose of retracting the wing blade 3. The blade mounting head 301 at one end of the wing blade 3 is fixedly connected to the blade connecting plate 802 by screws, improving the structural strength of the wing blade 3 and greatly extending the service life of the used wing blade 3.

[0062] At the upper end of the blade connecting plate 802, a first spring fixing member 804 is fixedly arranged. On the fixing plate 801, a second spring fixing member 805 corresponding to the first spring fixing member 804 is arranged. A second return spring 14 is fixedly arranged between the first spring fixing member 804 and the second spring fixing member 805. Inside the second return spring 14, a rubber rod 17 is arranged. One end of the rubber rod 17 is fixedly connected to the second spring fixing member 805, and the other end of the rubber rod 17 contacts the first spring fixing member 804. The rubber rod 17 limits the second return spring 14. The first spring fixing member 804 arranged on the blade connecting plate 802 and the second spring fixing member 805 on the fixing plate 801 are tensioned and fixed by the second return spring 14. Therefore, it is possible to prevent the wing blade 3 from rotating when not braking, avoiding damage to the flight path of the UAV. At the same time, a rubber rod 17 is also arranged inside the second return spring 14. One end of the rubber rod 17 is fixedly connected to the second spring fixing member 805, and the other end of the rubber rod 17 contacts the first spring fixing member 804. That is to say, the other end of the rubber rod 17 only contacts the first spring fixing member 804 and is not fixedly connected. In this case, the wing blade 3 will not rotate upward, so the wing blade 3 will not be stuck, improving the operation efficiency of the wing blade 3.

[0063] As Figure 8 and Figure 9 shown, for a UAV wing that is convenient to get rid of roadblocks, the bottom of the braking chamber 202 is connected with a fixed bottom plate 204. In the middle of the fixed bottom plate 204, a bottom plate through hole 207 and several extrusion part sliding holes 206 that are centrosymmetric about the bottom plate through hole 207 are opened;

[0064] The bottom of the cylindrical extrusion ring 9 is connected with an extrusion ring 903 through an extrusion ring guide post 901. The fixed part telescopic rod 503 passes through the extrusion ring through hole 902. The upper end of the fixing plate 801 passes through the bottom plate through hole 207 and is fixedly connected to the output end of the fixed part telescopic rod 503. A first return spring 13 is arranged between the cylindrical extrusion ring 9 and the fixed bottom plate 204. The upper end of the first return spring 13 is fixedly connected to the bottom surface of the cylindrical extrusion ring 9, and the lower end of the first return spring 13 is fixedly connected to the upper end surface of the fixed bottom plate 204;

[0065] The cylindrical extrusion ring 9 is arranged inside the electric motor braking part 2. The extrusion ring guide post 901 on the cylindrical extrusion ring 9 is slidably arranged inside the extrusion part sliding hole 206. Therefore, the cylindrical extrusion ring 9 can slide up and down on the fixed bottom plate 204. Further, the cylindrical extrusion ring 9 is fixedly connected to the fixed bottom plate 204 through the first return spring 13. That is to say, when the cylindrical extrusion ring 9 does not brake downward, under the action of the second return spring 14, the extrusion ring 903 below the cylindrical extrusion ring 9 is separated from the wing blade 3, avoiding the extrusion of the extrusion ring 903 on the wing blade 3 and causing the phenomenon of the wing blade 3 being stuck.

[0066] The extrusion ring guide post 901 penetrates through the slide hole 206 of the extrusion part, and the extrusion ring guide post 901 is vertically slidably arranged inside the slide hole 206 of the extrusion part. The cylindrical extrusion ring 9 is arranged inside the electric motor brake part 2. Among them, when the driving motor telescopic rod 10 brakes downward, the output end of the driving motor 4 abuts against the upper side surface of the cylindrical extrusion ring 9. When the driving motor 4 brakes downward, the bottom of the output end of the driving motor 4 extrudes the cylindrical extrusion ring 9. The extrusion ring guide post 901 slides inside the slide hole 206 of the extrusion part, and the extrusion ring 903 extrudes the blade connecting plate 802, causing the wing blade 3 to rotate downward.

[0067] The extrusion ring 903 is arranged outside the electric motor brake part 2, and the extrusion ring 903 does not contact the blade connecting part 8. Among them, when the driving motor telescopic rod 10 brakes downward, the extrusion ring 903 abuts against the blade connecting plate 802, and the downward rotation angle of the blade connecting plate 802 is 0-90°.

[0068] The specific principle is as follows: When the driving motor 4 brakes downward, the output end of the driving motor 4 extrudes the upper side surface of the cylindrical extrusion ring 9. The extrusion ring guide post 901 on the cylindrical extrusion ring 9 slides inside the slide hole 206 of the extrusion part. Therefore, under the action of this, the extrusion ring 903 extrudes the blade connecting plate 802 downward. The blade connecting plate 802 rotates downward under extrusion, and the rotation angle is 90°. In this way, the wing blade 3 will rotate downward, and the two wing blades 3 will fit together to avoid damage to the wing blade 3.

[0069] At the same time, the second return spring 14 between the first spring fixing part 804 and the second spring fixing part 805 deforms under tension. Once the driving motor 4 brakes upward, the second return spring 14 will return to its initial state, and the wing blade 3 can operate normally.

[0070] Furthermore, when the driving motor 4 brakes downward, the second driving gear 402 on the driving motor 4 is meshed and connected with the second driven gear 502, that is, it can still rotate slowly when the wing blade 3 is closed, so as to effectively get rid of roadblocks.

[0071] Such as Figure 1 and Figure 2A drone wing that facilitates getting rid of roadblocks is shown. A counterweight connecting block 505 is arranged between a first driven gear 501 and a second driven gear 502. The counterweight connecting block 505 is fixedly arranged on a driven shaft 504. A counterweight 6 is arranged on the counterweight connecting block 505. A counterweight assembly hole 601 matching the counterweight connecting block 505 is opened in the middle of the counterweight 6. Adding the counterweight 6 can make the drone land slowly under the action of inertia. Even in the case of a large separation, the safety of the drone can be effectively guaranteed, and the service life of the drone can be extended.

[0072] As Figure 10 A drone wing that facilitates getting rid of roadblocks is shown. One end of a wing blade 3 is fixedly provided with a blade mounting head 301. The blade mounting head 301 is of a U-shaped structure. The blade mounting head 301 is sleeved on one end of a blade connecting plate 802 and fixedly connected by screws, improving the installation stability of the wing blade 3.

[0073] The wing blade 3 includes a main blade 302 and a sub-blade 303. The upper side of the sub-blade 303 is lower than the upper side of the main blade 302. A reinforcing strip 15 is fixedly arranged inside the main blade 302. The reinforcing strip 15 is made of high-speed steel. A counterweight magnetic sheet 16 is arranged at one end of the main blade 302 away from the blade mounting head 301. The counterweight magnetic sheet 16 is arranged inside the wing blade 3. The wing blade 3 plays a crucial role in the drone. The strength of the wing blade 3 determines the service life of the drone. Therefore, arranging the reinforcing strip 15 in the wing blade 3 can further improve the structural strength of the wing blade 3 and extend the service life of the drone. The counterweight magnetic sheet 16 can bond the two wing blades 3 together. When the drone needs to get out of trouble, the wing blade 3 can be effectively protected.

[0074] As Figures 1 to 11 An operation method for a drone wing that facilitates getting rid of roadblocks is shown, including the following operation methods:

[0075] Blade closing and getting rid of obstacles: Start the driving motor telescopic rod 10 to push the driving motor 4 downward. The output end of the driving motor 4 abuts against the upper side of the cylindrical pressing ring 9. The pressing ring guide post 901 on the cylindrical pressing ring 9 slides inside the pressing part sliding hole 206 of the fixed bottom plate 204, so that the lower end surface of the pressing ring 903 abuts against the blade connecting plate 802. The blade connecting plate 802 rotates downward under the action of the pressing ring 903, and the rotation angle is 0-90°. When the wing blade 3 of the drone is stuck, the wing blade 3 on the blade connecting plate 802 can be rotated to achieve the purpose of getting rid of roadblocks.

[0076] The blades close and rotate to get rid of the obstacle: after starting the drive motor telescopic rod 10, if the drone does not get rid of the roadblock, the drive motor 4 is started, and when the drive motor telescopic rod 10 pushes, the second drive tooth 402 drives the rotation of the speed reducer 7, and the speed reducer 7 drives the blade connecting member 8 to rotate slowly, so that the wing blades 3 can move slowly when closed, so that the drone can get rid of the roadblock.

[0077] Pushing the support arm to get rid of the obstacle: When the UAV encounters an obstacle, for example, when it is hung on a tree, the wing blades 3 are stuck on the branches. The wing telescopic rod 102 on the UAV wing 1 can be activated to change the length of the UAV wing 1, thereby changing the center of gravity of the UAV to achieve the purpose of getting rid of the obstacle.

[0078] Shake to get rid of: start the vibration motor 11 inside the wing shaking member 101. When the vibration motor 11 is started, the wing 1 of the drone will shake violently under the action of the anisotropic cam 12, and while changing the center of gravity, the drone will get rid of the obstacle by using inertia.

[0079] A variety of escape methods can be used individually or in combination, which can greatly improve the efficiency of UAV escape and extend the service life of UAV.
