Abstract
Description
Technical Field
[0001] This invention relates to the field of drone protection technology, specifically to an automatic drone detachment and repair device. Background Technology
[0002] Drone landing can be divided into gliding and parachute descent. When landing site conditions do not allow for gliding or in emergency situations, drones generally land using a parachute, which requires the use of a suitable parachute to cushion and protect the drone during landing.
[0003] Currently, when using parachutes, they are often connected to the drone's fuselage via hooks. After the parachute opens and cushions the drone's descent, separating the parachute and drone for recovery requires the operator to locate the connection point from inside the parachute canopy scattered on the ground, open the hook, and detach the parachute from the drone's fuselage. This method not only increases the labor required for parachute separation and recovery but also reduces the efficiency of both parachute and drone recovery. Therefore, a new technical solution is needed. Summary of the Invention
[0004] The purpose of this invention is to provide an automatic unmounting and repair device for unmanned aerial vehicles (UAVs), which solves the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: an automatic unmounting and repair device for unmanned aerial vehicles (UAVs), comprising a housing, wherein mounting plates are fixedly installed on both sides of the top of the housing, and the number of mounting plates is four sets, wherein a lifting plate is slidably installed between the inner sides of every two sets of mounting plates, and a fixing rod is fixedly installed on the top middle surface of each lifting plate;
[0006] Each of the lifting plates has a push block fixedly installed on both ends of its side surface. Each of the mounting plates has an installation groove inside its middle side surface. Each of the mounting plates has a hollow frame fixedly installed on its middle outer side surface. Each of the hollow frames has a transmission plate slidably installed on its inner side surface. Each of the transmission plates has a connecting rod fixedly installed on its middle outer side surface, and the connecting rod is slidably installed inside the installation groove. Each connecting rod has a limit block fixedly installed on its top side surface.
[0007] Each of the mounting slots has an electromagnet fixedly mounted on both ends of its inner side surface, and the outer side of the connecting rod is attached to the outer surface of the electromagnet.
[0008] By adopting the above technical solution, the operation of the electromagnet generates a corresponding electromagnetic attraction force on the contact surface with the connecting rod, which limits the movement of the connecting rod inside the mounting groove. Combined with the mutual abutment of the pushing block and the limiting block, this prevents the lifting plate and the parachute connected to its top from detaching arbitrarily, thus affecting the protection quality for the drone landing. At the same time, it allows the operator to simply pull the parachute connected to the connecting ring outward to remove the lifting plate, facilitating the operator's step-by-step recovery of the parachute and the drone shell while improving recovery efficiency.
[0009] In a preferred embodiment of the present invention, a height sensor is fixedly installed on the bottom surface of the housing, and a controller is fixedly installed on the side surface of the bottom of the housing. The signal output terminal of the height sensor is electrically connected to the signal output terminal of the controller, and the signal output terminal of the controller is electrically connected to the signal input terminal of the electromagnet.
[0010] By adopting the above technical solution and electrically connecting the altitude sensor and the controller, the start and stop of the electromagnet can be automatically controlled, improving the automation of the electromagnet's start and stop operation, and thus improving the operator's efficiency in separating and recovering the parachute.
[0011] In a preferred embodiment of the present invention, a guide groove is provided inside the middle of the side of each hollow frame away from the mounting plate, and a movable rod is fixedly installed on the middle surface of the side of each transmission plate away from the mounting plate, and the movable rod is slidably installed inside the guide groove.
[0012] By adopting the above technical solution, the transmission rationality of the entire device is ensured by the guiding sliding action of the guide groove on the movable rod.
[0013] In a preferred embodiment of the present invention, a push spring is movably sleeved on the outer surface of each of the movable rods, and the top edge of the push spring is movably attached to the outer surface of the transmission plate.
[0014] By adopting the above technical solution, the lifting plate can be moved vertically and the positions of the connecting rod and the limiting block can be restored for subsequent installation and use by means of the structure of the pushing spring.
[0015] In a preferred embodiment of the present invention, connecting frames are fixedly installed on the four corner surfaces of the outer side of the fuselage, and an wing is rotatably installed on the top of the side of each connecting frame away from the fuselage. A landing gear is fixedly installed on the bottom surface of the fuselage.
[0016] In a preferred embodiment of the present invention, sliding rods are fixedly installed on both ends of the outer side of the lifting plate, and sliding grooves are opened inside both ends of the side of each mounting plate, with the top of the side of the sliding rod slidably installed inside the sliding groove.
[0017] By adopting the above technical solution, the sliding groove guides the sliding rod, ensuring that after the lifting plate is pulled, the lifting plate and the pushing block can only move vertically between the outer sides of the mounting plate without tilting, thus ensuring the rationality of subsequent transmission.
[0018] In a preferred embodiment of the present invention, a connecting ring is fixedly installed on the top surface of each of the fixed rods.
[0019] By adopting the above technical solution, the connecting rope at the bottom of the parachute can be easily passed through the inside of the connecting ring for use.
[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0021] This invention uses a connecting rod to slide a limiting block inside the mounting plate. Electromagnets are installed on both the front and rear sides of the mounting groove. The electromagnets, due to their electrical structure, generate an electromagnetic attraction force on the contact surface with the connecting rod during operation. This attraction and limitation restricts the movement of the connecting rod within the mounting groove, preventing the connecting rod and its triangular limiting block from moving horizontally at the top of the casing. The limiting block can then abut and limit the pushing block, preventing the lifting plate and the parachute connected to its top from detaching and affecting the protection quality for the drone landing. Furthermore, the contact between the pushing block and the limiting block abuts the limiting block and the connecting rod, causing the electromagnets to stop and lose their electromagnetic attraction force. This allows the operator to simply pull the parachute connected to the connecting ring outwards to remove the lifting plate, facilitating the step-by-step recovery of the parachute and casing while improving recovery efficiency.
[0022] By installing a height sensor at the bottom of the fuselage, the height information between the bottom of the fuselage and the ground can be collected. Then, by combining the functions of the controller itself, the collected information can be judged, analyzed and processed to automatically control the start and stop of the electromagnet, thereby improving the automation of the electromagnet's start and stop operation and thus improving the operator's efficiency in separating and recovering the parachute.

The model numbers of the electrical appliances provided in this invention are for reference only, and different models of electrical appliances with the same function can be replaced according to actual usage.
[0032] Please see Figure 1-4The present invention provides a technical solution: a height sensor 33 is fixedly installed on the bottom surface of the housing 1, a controller 32 is fixedly installed on the bottom side surface of the housing 1, an electromagnet 31 is fixedly installed on both ends of the inner side of each mounting slot 24, and the outer side of the connecting rod 28 is attached to the outer surface of the electromagnet 31. The signal output end of the height sensor 33 is electrically connected to the signal output end of the controller 32, and the signal output end of the controller 32 is electrically connected to the signal input end of the electromagnet 31.
[0033] In an optional embodiment, mounting plates 2 are fixedly installed on both sides of the top of the housing 1, and there are four sets of mounting plates 2. A lifting plate 21 is slidably installed between the inner sides of every two sets of mounting plates 2. A fixing rod 4 is fixedly installed on the top middle surface of each lifting plate 21. A connecting ring 41 is fixedly installed on the top surface of each fixing rod 4. Pushing blocks 23 are fixedly installed on both sides of each lifting plate 21. A mounting groove 24 is opened inside the middle side of each mounting plate 2. A hollow frame 26 is fixedly installed on the middle outer surface of each mounting plate 2. A transmission plate 27 is slidably installed on the inner side surface of each hollow frame 26. A connecting rod 28 is fixedly installed on the middle outer surface of each transmission plate 27. The connecting rod 28 is slidably installed inside the mounting groove 24. A limit block 25 is fixedly installed on the top side surface of each connecting rod 28.
[0034] In an optional embodiment, a guide groove 3 is provided inside the middle of the side of each hollow frame 26 away from the mounting plate 2, and a movable rod 51 is fixedly installed on the middle surface of the side of each transmission plate 27 away from the mounting plate 2, and the movable rod 51 is slidably installed inside the guide groove 3.
[0035] In an optional embodiment, a push spring 29 is movably sleeved on the outer surface of each movable rod 51, and the top edge of the push spring 29 is movably attached to the outer surface of the transmission plate 27.
[0036] In an optional embodiment, sliding rods 22 are fixedly installed on both ends of the outer side of the lifting plate 21, and sliding grooves 5 are opened inside both ends of the side of each mounting plate 2, and the top of the side of the sliding rod 22 is slidably installed inside the sliding groove 5.
[0037] In an optional embodiment, connecting frames 11 are fixedly installed on the four outer corner surfaces of the housing 1, and a wing 12 is rotatably installed on the top of the side of each connecting frame 11 away from the housing 1. A landing gear 13 is fixedly installed on the bottom surface of the housing 1.
[0038] During operation, when the drone needs to be parachuted, the controller 32 is activated, simultaneously deploying the parachute on the top of the casing 1 to buffer and slow the descent. This allows the altitude sensor 33 to collect altitude information between the bottom of the casing 1 and the landing surface. Before the bottom surface of the landing gear 13 touches the ground, the controller 32 simultaneously activates the electromagnet 31, causing it to generate an electromagnetic attraction force on the outer contact surface of the connecting rod 28. This attraction and limit the movement of the connecting rod 28 within the mounting slot 24, preventing the connecting rod 28 and its side triangular limiting block 25 from arbitrarily moving horizontally on the top of the casing 1. The limiting block 25 then acts as a stop for the pushing block 23, preventing the lifting plate from moving arbitrarily. The parachute 21 and its top are arbitrarily detached until the bottom surface of the landing gear 13 is in contact with the landing site surface. After the altitude sensor 33 detects the corresponding altitude information, the electromagnet 31 is turned off under the control of the controller 32, so that the connecting rod 28 can move inside the mounting slot 24. The operator pulls the parachute outward, causing the connecting ring 41 and the lifting plate 21 to move vertically inside the mounting plate 2. After the inclined surfaces of the pushing blocks 23 at both ends of the side of the lifting plate 21 are in contact with the inclined surfaces of the limiting blocks 25, the limiting blocks 25 and the connecting rod 28 are pushed, causing them to move outward inside the mounting slot 24. This allows the lifting plate 21 to be moved out between the inner sides of the two sets of mounting plates 2, thus facilitating the separation of the parachute and the housing 1.
