Description

Technical Field

[0001] This invention relates to the field of unmanned aerial vehicle (UAV) technology, specifically to a UAV equipped with a throwing device. Background Technology

[0002] Drones operate using wireless remote control and their own programs and devices. When needed, they can carry items and drop them to predetermined locations. In emergency rescue operations, drones can be used to carry relevant emergency rescue items to provide trapped personnel with the necessary tools to reach them.

[0003] According to a search, Chinese patent with publication number CN211076341U discloses a drone throwing device and a drone. One of the technical effects of this utility model is that the throwing component is not affected by any obstacles and can be more accurately thrown to the target point.

[0004] When throwing rope emergency supplies, the above-mentioned technical solution can only throw the items inside the throwing device by opening and closing the door. This throwing method can only be used for regular items. However, when throwing a bundled rope, the rope, which has not been straightened, will become tangled before being thrown. This makes it impossible to throw the rope to the trapped person in a near-circular shape, which makes it difficult for the trapped person to accurately catch the rope and the emergency supplies carried on it. Summary of the Invention

[0005] The purpose of this invention is to provide a drone with a throwing device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a drone with a throwing device, comprising a drone body, landing gears obliquely mounted on both sides of the bottom of the drone body, multi-rotor arms mounted on the periphery of the drone body, and a support located between the two landing gears at the bottom of the drone body.

[0013] Preferably, the bottom end of the arched frame is fixed with an arc-shaped rail, one end of the arc-shaped rail is fixed with a positioning sleeve, the middle of the positioning sleeve is rotatably connected with a retaining sleeve, and the middle of the retaining sleeve is provided with a C-shaped opening.

[0014] The end of the ferrule away from the irregularly shaped wheel is fixed with a spiral column, and the surface of the spiral column is provided with a spiral groove;

[0015] One end of the drive shaft is provided with a cuboid block that matches the width of the C-shaped opening, and the inner width of the arc-shaped rail matches the width of the cuboid block.

[0016] A driving component is sleeved on the outer side of the spiral column, and a protrusion that mates with the spiral groove is fixed on the inner side wall of the driving component.

[0018] A servo motor is mounted on the top surface of the fixed base, and a swing arm is mounted on the output end of the servo motor. An adjustment port for docking with the swing arm is opened on the surface of the toothed plate.

[0019] Preferably, an anti-slip sleeve is fitted between the flat wheel and the irregularly shaped wheel;

[0020] A motor is installed inside the flat wheel, and friction wheels that can drive the anti-slip wheel sleeve to rotate are embedded at equal angles around the central column of the flat wheel.

[0021] The bottom of the flat disc is provided with a gear set that respectively connects to the motor output end and the friction wheel.

[0022] Preferably, the tensioning mechanism includes a traction column inserted into the hollow rotating sleeve, and a guide frame that is sleeved through the traction column is installed on the top of the support platform. A spring for pushing the traction column is sleeved on the guide frame.

[0023] Preferably, a rack is fixedly offset on the upper surface of the support platform, and a steering gear is fixed at the top of the hollow rotating sleeve to mesh with the rack for transmission. The angle of the release mechanism is horizontally rotated by the steering gear that meshes with and rolls with the rack.

[0029] Compared with the prior art, the beneficial effects of the present invention are as follows: The drone with a throwing device adjusts the attached rope and throwing object to below the landing gear through the folding device. The straightening mechanism expands the taut rope, causing the two release mechanisms to move closer together. Then, the tensioning mechanism adjusts the direction of the flat and irregularly shaped discs that move closer together. In this way, the release mechanism and the straightening mechanism work together to pull and straighten the rope, which is expanded into a near-circular shape. Finally, the irregularly shaped disc of the release mechanism presses down, thereby throwing the rope, which is expanded into a near-circular shape, downward. This makes it convenient for trapped personnel to accurately catch the emergency rope and the emergency items carried on the rope. Attached Figure Description

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] Please see Figure 1 and Figure 2 This invention provides a technical solution: a drone with a throwing device, comprising a drone body 1, landing gear 101 obliquely mounted on both sides of the bottom of the drone body 1, multi-rotor arms 2 mounted on the periphery of the drone body 1, and a support 3 located between the two landing gears 101 at the bottom of the drone body 1. The multi-rotor arms 2 provide the drone body 1 with the power for takeoff and landing. The ends of the arms 2 are equipped with anti-collision sleeves to protect the rotors at the ends of the arms 2 from collisions. When the drone body 1 takes off or lands, the landing gear 101 buffers the drone body 1 for takeoff and landing and stabilizes it. The support 3 provides a mounting position for the load on the bottom of the drone body 1.

[0044] Please see Figures 1-5 Below the support 3 is a folding device 4 for height lifting. Below the folding device 4 is a support platform 5. The folding device 4 consists of an upper frame installed below the support 3, a lower frame above the support platform 5, and an X-shaped scissor arm that movably connects the upper and lower frames. Below the support 3 is an electric push rod for adjusting the opening degree of the scissor arm. The folding device 4 folds and lifts the support platform 5 to adjust the distribution position of the object to be thrown and the landing gear 101.

[0045] In this embodiment, the X-shaped scissor arm is opened by activating the electric push rod of the folding device 4. The opened X-shaped scissor arm pushes the lower frame and the carrier platform 5 to descend, causing the carrier platform 5 to move downward between the two landing gears 101. The descending carrier platform 5 then drives the bottom-mounted projectile to move down and out between the two landing gears 101. This allows the projectile, initially located between the two landing gears 101, to be lowered below the two landing gears 101, ensuring that the projectile is restricted by the two landing gears 101 during loading and transportation. Furthermore, it descends below the landing gears 101 during the throwing process to prevent collision or entanglement with the landing gears 101, ensuring that the throwing operation can be carried out smoothly.

[0046] Please see Figures 1-8A straight rail 501 is symmetrically fixed below the support platform 5. A release mechanism 6 is provided below the support platform 5 near the straight rail 501. The rope-thrown object is restricted by two sets of release mechanisms 6. The release mechanism 6 includes an arched frame 601 that slides with the straight rail 501. A hollow rotating sleeve runs longitudinally through the upper end of the arched frame 601.

[0047] Below the hollow rotating sleeve are an integrally formed flat disc 604 and an irregularly shaped disc 6041. The irregularly shaped disc 6041 consists of a horizontal semi-circular disc and an inclined semi-circular disc. A sector-shaped seat is fixed between the horizontal and inclined semi-circular discs. The lower end of the hollow rotating sleeve is connected to the sector-shaped seat via a drive shaft 605. A limiting tube is provided at the corner between the horizontal and inclined semi-circular discs, which is inserted into the drive shaft 605. A strip pin is fixed to the inner wall of the limiting tube. A groove is provided on the cylindrical surface of the drive shaft 605 to engage with the strip pin. An arc-shaped transition surface is provided between the inclined semi-circular disc and the flat disc 604. The arc-shaped transition surface connects the inclined semi-circular disc and the flat disc 604. When the flat disc 604 and the irregularly shaped disc 6041 rotate around the drive shaft 605, it can prevent the rope from getting stuck under the inclined semi-circular disc and causing throwing jamming.

[0048] In this embodiment, the upper side of the arch frame 601 is slidably connected to the straight rail 501 below the support platform 5. Then, the sector seat between the horizontal semi-circular disk and the inclined semi-circular disk is inserted into the lower end of the hollow rotating sleeve. Subsequently, the groove on the cylindrical surface of the drive shaft 605 is connected to the strip pin on the inner wall of the limiting tube, and the cylindrical end of the drive shaft 605 is inserted into the middle of the hollow rotating sleeve. When the drive shaft 605 is rotated, the drive shaft 605 will drive the flat wheel 604 and the irregular wheel 6041 to rotate around the hollow rotating sleeve, thereby releasing the restriction on the rope throwing object.

[0049] In addition, when the hollow rotating sleeve rotates inside the arch frame 601, the hollow rotating sleeve can drive the flat wheel 604 and the irregular wheel 6041 to rotate horizontally by the drive shaft 605 that passes through the fan-shaped seat and the limiting tube at the bottom end, so as to ensure that the flat wheel 604 and the irregular wheel 6041 of the release mechanism 6 can pull and straighten the rope that is tied in the ring when rotating horizontally.

[0050] It should be noted that the tilted semicircular disk of the irregular wheel 6041 is initially tilted, and there is no rotational gap between the tilted semicircular disk and the hollow rotating sleeve. The horizontal semicircular disk is initially horizontal, and it is perpendicular to the hollow rotating sleeve. Therefore, when the flat wheel 604 and the irregular wheel 6041 rotate, the flat wheel 604 can move closer to the hollow rotating sleeve. When the horizontal semicircular disk and the hollow rotating sleeve move closer to each other, the tilted semicircular disk can press down on the rope-thrown object. At the same time, the flat wheel 604, which rotates synchronously with the irregular wheel 6041, will rotate to the tilt angle, thus avoiding the rope-thrown object thrown downwards.

[0051] Please see Figures 3-9 An arc-shaped rail 602 is fixed to the bottom of the arched frame 601. A positioning sleeve 6021 is fixed to one end of the arc-shaped rail 602. A retaining sleeve 603 is rotatably connected to the middle of the positioning sleeve 6021, and a C-shaped opening is provided in the middle of the retaining sleeve 603. A spiral column 6031 is fixed to the end of the retaining sleeve 603 away from the irregular wheel 6041, and a spiral groove is provided on the surface of the spiral column 6031. A cuboid block matching the width of the C-shaped opening is provided at one end of the drive shaft 605, and the inner width of the arc-shaped rail 602 matches the width of the cuboid block.

[0052] A driving component 6032 is sleeved on the outer side of the spiral column 6031, and a protrusion 6033 that mates with the spiral groove is fixed on the inner side wall of the driving component 6032.

[0053] In this embodiment, when the cuboid block at one end of the drive shaft 605 is located inside the arc-shaped rail 602, the arc-shaped rail 602 will restrict the rotation of the drive shaft 605, so the flat wheel 604 will remain in a horizontal position. Therefore, the cooperation between the flat wheel 604 and the irregular wheel 6041 can lock and restrict the rope-thrown object to prevent the rope-thrown object from becoming loose.

[0054] When the hollow rotating sleeve drives the flat wheel 604, the irregular wheel 6041 and the drive shaft 605 to adjust the horizontal angle, the cuboid block at one end of the drive shaft 605 will slide along the arc track 602. At this time, the inclined semi-circular disk of the irregular wheel 6041 will flip outward horizontally, thereby gradually releasing the restriction on the upper position of the rope-thrown object.

[0055] To enable the flat wheel 604 and the irregular wheel 6041 to flip and release the rope-thrown object, the cuboid block at one end of the drive shaft 605 is first slidably engaged into the C-shaped opening in the middle of the sleeve 603. At this time, by pushing the drive member 6032 in the forward direction, the protrusion 6033 on the inner sidewall of the drive member 6032 moves forward along the spiral groove on the surface of the spiral column 6031, thereby enabling the spiral column 6031 to drive the sleeve 603 to rotate in the forward direction within the positioning sleeve 6021. The rotating sleeve 603 will rotate along one end of the arc track 602, thereby causing the sleeve 603 to drive the cuboid block and the drive shaft 605 to rotate at an angle. Then, the forward-rotating drive shaft 605 will drive the limiting tube, the irregular wheel 6041, and the flat wheel 604 to rotate at an angle, ensuring that the inclined semi-circular disc of the irregular wheel 6041 presses down on the rope, thereby enabling the release and throwing of the rope-thrown object.

[0056] Conversely, in order to retract the flat disc 604 and the irregular disc 6041, the reverse traction drive component 6032 is used to cause the ferrule 603 to drive the drive shaft 605, the irregular disc 6041 and the flat disc 604 to rotate in the opposite direction, thereby rotating the irregular disc 6041 and the flat disc 604 back to their original positions. At this time, after the C-shaped opening of the ferrule 603 is aligned with the opening at one end of the arc-shaped rail 602, the cuboid block at one end of the drive shaft 605 can smoothly slide into the arc-shaped rail 602.

[0057] Please see Figures 1-8 The flat wheel 604 has a semi-circular notch on the circumferential edge away from the inclined semi-circular disc, and the horizontal semi-circular edge of the irregular wheel 6041 has a semi-circular notch. When the flat wheel 604 and the horizontal semi-circular disc are used to lock and restrict the rope throwing object, the vertical position of the rope can be restricted. At the same time, when the flat wheel 604 rotates, its notch can avoid the arc-shaped rail 602, thereby reducing the size design of the arc-shaped rail 602. When the horizontal semi-circular disc flips, its notch can avoid the inner wall of the arched frame 601, which can also reduce the size design of the arc-shaped rail 602.

[0058] Please see Figures 5-9 The upper side of the drive component 6032 is designed with a toothed surface. A slide frame is fixed on the side of the drive component 6032 near the toothed surface. A fixed seat that is laterally slidably connected to the slide frame is welded to one side of the arched frame 601. A toothed plate 606 for driving the drive component 6032 to move laterally is rotatably connected to one side of the fixed seat. The drive component 6032 is laterally anti-fall slidable through the slide frame and the fixed seat to ensure that the drive component 6032 can stably mesh with the toothed plate 606 when moving laterally.

[0059] A servo motor 607 is mounted on the top surface of the fixed base, and a swing arm 6071 is mounted on the output end of the servo motor 607. An adjustment port for docking with the swing arm 6071 is opened on the surface of the gear plate 606.

[0060] In this embodiment, when the cuboid block at one end of the drive shaft 605 is engaged in the C-shaped opening of the sleeve 603, the servo motor 607 is activated to drive the swing arm 6071 to rotate. As a result, the swing arm 6071 will rotate along the adjustment port by pressing the toothed plate 606. The rotating toothed plate 606 engages with the toothed surface on the upper side of the drive member 6032 to make the drive member 6032 move in the forward direction. This ensures that the servo motor 607, which is running in the forward direction, can drive the flat wheel 604 and the irregular wheel 6041 to rotate in the forward direction, thereby achieving the effect of releasing the rope-thrown object. Conversely, the servo motor 607, which is running in the reverse direction, can drive the flat wheel 604 and the irregular wheel 6041 to rotate in the reverse direction, thereby achieving the effect of resetting and returning to the center position.

[0061] In order to adjust the position of the bundled rope between the two release mechanisms 6, and thus prevent the knotted position of the rope from affecting the rotation of the flat wheel 604 and the irregular wheel 6041, the release mechanism 6 is also provided with the following features:

[0062] Please see Figures 1-7 An anti-slip sleeve 608 is fitted between the flat wheel 604 and the irregular wheel 6041. A motor 6081 is installed inside the flat wheel 604. Friction wheels 6082, which can drive the anti-slip sleeve 608 to rotate, are embedded at equal angles around the central column of the flat wheel 604. A gear set 6083 is provided at the bottom of the flat wheel 604, which respectively connects to the output end of the motor 6081 and the friction wheel 6082.

[0063] In this embodiment, by activating the motor 6081 located inside the flat wheel 604, the gear set 6083 drives the friction wheel 6082 to rotate in the same direction. The rotating friction wheel 6082 then drives the anti-slip sleeve 608 to rotate around the central column of the flat wheel 604 through rolling friction. At this time, the ropes restricted on the two release mechanisms 6 will rotate with the anti-slip sleeve 608, thereby adjusting the placement of the ropes and facilitating the adjustment of the knot position of the ropes and the position distribution of the release mechanisms 6, preventing the knot position of the ropes from affecting the horizontal rotation of the flat wheel 604 and the irregular wheel 6041.

[0064] In addition, to ensure that the thrown rope can meet the emergency supplies needs of the trapped personnel, other emergency supplies can be tied to the rope. To do this, the anti-slip wheel sleeve 608 is used to adjust the position of the rope, so that the position of other emergency supplies can be changed during subsequent rope throwing to facilitate the throwing operation.

[0065] To ensure that the two release mechanisms 6 can tighten and limit the tension of the bundled ropes, the following features are also provided:

[0066] Please see Figure 2 , Figure 3 and Figure 5 A tensioning mechanism 8 is provided on the upper surface of the support platform 5 away from the straight rail 501. The tensioning mechanism 8 can elastically tighten the rope restricted by the release mechanism 6. The tensioning mechanism 8 includes a traction column 803 inserted into the hollow rotating sleeve. A guide frame 804 is installed on the top of the support platform 5 and is sleeved through the traction column 803. A spring 805 for pushing the traction column 803 is sleeved on the guide frame 804. Strip-shaped reserved grooves are opened on the surfaces at both ends of the support platform 5 for adjusting the lateral movement of the hollow rotating sleeve.

[0067] In this embodiment, the spring 805 on the guide frame 804 pushes the traction column 803, which in turn pushes the hollow rotating sleeve, and the hollow rotating sleeve moves horizontally along the strip-shaped reserved groove on the surface of the support platform 5.

[0068] In the initial state, the spring 805 will push the hollow rotating sleeve to the end of the support platform 5, so that the release mechanism 6 under the two hollow rotating sleeves is in a state of being far apart from each other. At this time, the release mechanism 6, which is far apart from each other, can use the flat wheel 604 and the irregular wheel 6041 to tighten and limit the rope-thrown object.

[0069] When the two release mechanisms 6 are squeezed together, the release mechanism 6 will drive the traction column 803 in the middle of the hollow rotating sleeve to squeeze the spring 805 located on the guide frame 804.

[0070] To ensure that the two release mechanisms 6 can release the restriction on the upper position of the rope when they come close together, the tensioning mechanism 8 is also equipped with the following features:

[0071] Please see Figure 2 , Figure 3 and Figure 5 A rack 801 is fixed to the upper surface of the support platform 5 in a staggered manner. A steering gear 802 that meshes with the rack 801 is fixed to the top of the hollow rotating sleeve. The angle of the release mechanism 6 is horizontally rotated by the steering gear 802 that meshes with the rack 801 and rolls.

[0072] In this embodiment, when the two release mechanisms 6 drive the hollow rotating sleeve to move to the end position of the support platform 5 and are in a state of being far apart from each other, the meshing restriction of the rack 801 on the steering gear 802 will cause the horizontal semi-circular disks of the flat wheel 604 and the irregular wheel 6041 to simultaneously restrict the rope.

[0073] When the two release mechanisms 6 are squeezed and brought closer together, the inclined semi-circular disc of the irregular wheel 6041 will rotate to the upper position of the rope. This means that the object thrown by the rope is only supported by the flat wheel 604, and the restriction of the upper position of the rope by the irregular wheel 6041 is removed. This allows the irregular wheel 6041 to have sufficient clearance for flipping and pressing down, ensuring that the flat wheel 604 can tilt and avoid the downward-thrown rope when the irregular wheel 6041 flips and presses down.

[0074] To ensure the thrown rope opens into a near-circular shape upon descent, allowing trapped individuals to accurately catch the object and preventing difficulties caused by tangled ropes, the following features are specifically included:

[0075] Please see Figures 1-5 , Figure 10 andFigure 11 A rotatable straightening mechanism 7 is provided below the middle of the support platform 5. The distance between the two release mechanisms 6 is adjusted by rotating and tightening the rope throwing object through the straightening mechanism 7. The straightening mechanism 7 and the release mechanism 6 are used to adjust the opening of the rope throwing object to straighten the rope that is tied in a ring. The straightening mechanism 7 includes a support platform 701 suspended and installed on the lower side of the support platform 5. When the two release mechanisms 6 are far apart and the rope throwing object is tightened, the two sides of the support platform 701 support the straightened rope to prevent the rope from drooping in the middle and getting caught on tree branches during air transport.

[0076] The surface of the support platform 701 is provided with staggered arc-shaped grooves 7011. The arc-shaped grooves 7011 and the support platform 701 are eccentrically set. A telescopic rod 702 is rotatably connected to the support platform 701. A lever 7021 is fixed on the upper side of the outer tube of the telescopic rod 702. A guide pin 7022 is fixed on the inner rod of the telescopic rod 702 and slides through the outer tube. The guide pin 7022 is slidably connected to the arc-shaped grooves 7011. An arc-shaped support plate 703 is movably connected to the end of the inner rod of the telescopic rod 702.

[0077] A servo motor 704 is installed on the bottom wall of the support platform 701. The output end of the servo motor 704 is connected to a dial 705. The two sides of the dial 705 have U-shaped openings that connect with the lever 7021.

[0078] In this embodiment, when the UAV body 1 is transporting the rope-thrown object, the arc-shaped support plate 703 abuts against the inner side of the rope. In order to stretch and straighten the rope before throwing it, the servo motor 704 is started to drive the dial 705 to rotate. The dial 705 will then rotate the outer tube of the telescopic rod 702 through the U-shaped openings on both sides, causing the outer tube to drive the inner rod and the arc-shaped support plate 703 to rotate outward. At this time, the inner rod of the telescopic rod 702 will move along the arc-shaped groove 7011 on the surface of the support platform 701 through the guide pin 7022, so that the inner rod of the telescopic rod 702 can drive the arc-shaped support plate 703 to squeeze the rope when rotating.

[0079] When the telescopic rod 702 drives the arc-shaped support plate 703 to rotate and squeeze the rope open, the opened rope will squeeze the two release mechanisms 6 inward, causing the two release mechanisms 6 to move closer to each other. When the two release mechanisms 6 move closer to each other, the tensioning mechanism 8 adjusts the horizontal direction of the flat wheel 604 and the irregular wheel 6041. Thus, the opening and rotation of the arc-shaped support plate 703 on both sides of the rope can cause friction and pulling between the tied rope and the anti-slip wheel sleeve 608.

[0080] Since the flat wheel 604 and the irregular wheel 6041 rotate horizontally, they will drive the anti-slip wheel sleeve 608 and the arc-shaped support plate 703 to rotate in opposite directions. Therefore, when the anti-slip wheel sleeve 608 and the arc-shaped support plate 703 rotate in opposite directions, they will pull and open the nearly circular rope, ensuring that the rope can be tightened and shaped when it is ready to be thrown. When the release mechanism 6 presses down and flips the rope opened by the shaping mechanism 7, the nearly circular rope can be thrown to the designated position, ensuring that the trapped personnel can accurately catch the thrown rope.

[0081] It should be noted that when the two arc-shaped support plates 703 of the orthotic mechanism 7 spread the rope, the motor 6081 will not run, ensuring that the anti-slip wheel sleeve 608 is in a stationary state. As a result, the spreading and rotating of the rope by the arc-shaped support plates 703 and the anti-slip wheel sleeve 608 can achieve stable tension and tightening. When the dial 705 reverses, it will drive the arc-shaped support plates 703 to retract and reset to the initial position.
