Description

Technical Field

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

[0002] Unmanned aerial vehicles (UAVs) are aircraft that do not require an onboard pilot and can fly autonomously or semi-autonomously through radio remote control equipment or onboard computer program control systems. UAV maintenance equipment is a general term for specialized equipment or systems used to carry out operations such as testing, disassembly, repair, calibration, and maintenance on components such as the UAV airframe, power system, flight control system, and mission payload.

[0003] A search revealed a Chinese patent (patent application number 202320613411.2) disclosing a repair device for unmanned aerial vehicles (UAVs). It includes a main body, a workbench, and a fixing mechanism. The fixing mechanism includes a movable groove formed on one side of the main body. An elastic component is disposed inside the movable groove. One end of the elastic component is located on the outside of the main body and is fixedly connected to a movable plate. A fixed support rod is disposed inside the movable plate. A movable fixing plate is fixedly connected to the other end face of the fixed support rod. A small clamp is movably connected to the other side surface of the movable fixing plate. Through this fixing mechanism, when repairing a UAV using the repair device, the UAV can be better secured to the small clamp, eliminating the need for additional personnel to manually fix the UAV, making the repair work simpler and saving manpower.

[0004] However, during the aforementioned drone repairs, the drone is often placed directly on the control panel, making precise clamping impossible. The external forces generated during repair operations can easily cause the drone to shift or tip over, affecting repair accuracy and potentially causing secondary damage. Excessive clamping force can cause crushing damage to the drone's shell, thus ensuring the safety of the repair operation.

[0005] Therefore, a drone repair device is needed to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide a drone repair device that enables initial clamping of the drone, quickly confining it within a preset operating area to prevent horizontal slippage during repair. Simultaneously, rotating the third screw pushes the fixing pad to conform to the shape of the drone, completing adaptive fixation. This not only enhances the clamping firmness but also prevents excessive clamping force from causing squeezing damage to the drone shell through the flexible contact of the fixing pad, thus ensuring the safety of the repair operation.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a drone repair device, including a repair station; A fixing unit is placed on the top surface of a maintenance table. The fixing unit includes a placement tray, a first screw is rotatably connected to the bottom of the placement tray, a sleeve block is sleeved on the outer wall of the first screw, a connecting plate is hinged to the inner side of the sleeve block, a limit block is hinged to the end of the connecting plate away from the sleeve block, a limit frame is connected to the top surface of the limit block, a second screw is rotatably connected inside the limit frame, and a retaining frame is sleeved on the outer wall of the second screw. A rotating unit is located outside the fixed unit.

[0008] Preferably, a third screw is sleeved at the end of the card frame, and a fixing pad is connected to the end of the third screw.

[0009] Preferably, the placement tray has a groove inside, and the outer wall of the limiting block is slidably disposed with the groove inside the placement tray. Under its restriction, the rotating first screw can drive the sleeve block to move up and down, causing the sleeve block to pull the limiting block through the connecting plate, so that the limiting block slides inside the placement tray.

[0010] Preferably, there are two card frames symmetrically distributed around the center of the placement disk. Under the constraint of the two opposing moving card frames, the drone can be clamped in an external card sleeve manner.

[0011] Preferably, the fixing pad is made of rubber and is placed inside the frame. The rubber fixing pad increases the friction coefficient between the fixing pad and the drone while preventing scratches on the drone surface.

[0012] Preferably, the rotating unit includes a groove formed on the top surface of the maintenance table, and a limiting ring is slidably provided inside the groove; The bottom of the maintenance platform is connected to a fixed rod, the end of the fixed rod is connected to a first magnetic ring, a sliding sleeve is slidably provided on the outer wall of the fixed rod, a second magnetic ring is connected to the bottom of the sliding sleeve, a ring is connected to the outer wall of the sliding sleeve, and a retaining ring is fitted inside the ring.

[0013] Preferably, the top surface of the retaining ring is connected to the bottom of the placement tray, and the inner surface of the limiting ring is fitted with the outer wall of the placement tray. Under the restriction of the limiting ring, the placement tray can rotate stably in the groove opened inside the maintenance table. Under the restriction of the retaining ring and the ring-fitting sleeve, the placement tray after rotation adjustment can be positioned.

[0014] Preferably, the first magnetic ring and the second magnetic ring are magnetically repulsive, and the interior of the second magnetic ring is slidably disposed with respect to the outer wall of the fixing rod. Under the restriction of magnetic repulsion, the ring and the retaining ring can be stably engaged, preventing the placement plate from rotating inside the ring groove.

[0015] Compared with the prior art, the beneficial effects of the present invention are: This invention allows for the initial clamping of a drone during maintenance. The drone is placed on the top surface of a mounting tray, and the first screw is rotated. Under the limiting action of the mounting tray's groove, the screw moves a sleeve block, which, via a connecting plate, pulls two opposing limiting blocks. These limiting blocks then move the top limiting frame and the inner locking frame synchronously, achieving initial clamping of the drone. This quickly confines the drone to a preset operating area, preventing horizontal slippage during maintenance. For drones of different heights, the second screw is rotated, utilizing the sliding engagement between the locking frame and the limiting frame to adjust the frame height for a suitable fixation. This accommodates drones of various sizes, enhancing the device's applicability and versatility. For precise clamping, the third screw is rotated to push the fixing pad against the drone's shape, achieving adaptive fixation. This enhances the clamping's strength and, through the flexible contact of the fixing pad, prevents excessive clamping force from causing damage to the drone's shell, ensuring the safety of the maintenance operation. In this invention, after the drone is securely fixed by the fixing unit, if other parts need to be repaired, simply pull the loop to move the sliding sleeve down along the fixing rod, which releases the engagement between the loop and the retaining ring at the bottom of the placement plate. Then, rotate the placement plate so that it rotates smoothly along the groove of the outer wall limit ring, thereby driving the drone to adjust its orientation synchronously. After the drone is adjusted to the target repair orientation, release the loop. Under the repulsive magnetic force of the first and second magnetic rings, the second magnetic ring drives the sliding sleeve and loop to automatically move upward and reset, re-engaging with the retaining ring to lock the drone's orientation. This structure allows for flexible rotation and adjustment of the drone in a fixed state, enabling multi-part repairs without repeated clamping of the drone. This simplifies the repair operation steps, shortens the overall repair time, and effectively avoids secondary damage to the drone's shell and components caused by improper disassembly and assembly during repeated assembly, ensuring the safety and stability of the repair process.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0029] Example 1: A preferred embodiment of the UAV repair device provided by the present invention Figures 1 to 8 As shown: A drone repair device, including a repair station 3; Fixing unit 1 is placed on the top surface of maintenance table 3. Fixing unit 1 includes a placement tray 11. A first screw 12 is rotatably connected to the bottom of the placement tray 11. A sleeve block 13 is sleeved on the outer wall of the first screw 12. A connecting plate 14 is hinged to the inner side of the sleeve block 13. A limiting block 15 is hinged to the end of the connecting plate 14 away from the sleeve block 13. A limiting frame 16 is connected to the top surface of the limiting block 15. A second screw 17 is rotatably connected inside the limiting frame 16. A retaining frame 18 is sleeved on the outer wall of the second screw 17. A third screw 19 is fitted at the end of the card frame 18, and a fixing pad 110 is connected to the end of the third screw 19; Rotating unit 2 is located outside of fixed unit 1.

[0030] The placement tray 11 has a groove inside, and the outer wall of the limiting block 15 is slidably set with the groove inside the placement tray 11. Under its restriction, the rotating first screw 12 can drive the sleeve block 13 to move up and down, causing the sleeve block 13 to pull the limiting block 15 through the connecting plate 14, so that the limiting block 15 slides inside the placement tray 11.

[0031] There are two card frames 18, which are symmetrically distributed around the center of the placement disk 11. Under the constraint of the two opposing moving card frames 18, the drone can be clamped in an external card sleeve manner.

[0032] Among them, the fixing pad 110 is made of rubber, and the fixing pad 11 is placed inside the frame 18. Under the restriction of the rubber fixing pad 110, the friction coefficient between it and the drone can be increased, while avoiding scratching the surface of the drone.

[0033] In this embodiment, when repairing the drone, it is placed on the top surface of the placement tray 11. The first screw 12 is rotated. Due to the sliding fit between the outer wall of the limiting block 15 and the groove opened inside the placement tray 11, the rotating first screw 12 drives the sleeve block 13 fitted on its outer wall to move under the limiting action of the groove. This causes the sleeve block 13 to pull the limiting block 15 through the connecting plate 14, so that the two limiting blocks 15 respectively drive the limiting frame 16 fixedly installed on its top surface to move in opposite directions. The limiting frame 16 drives the locking frame 18 slidably set inside it to move synchronously. The two locking frames 18 can form a stable clamping on the outer wall of the drone, effectively preventing the drone from undergoing horizontal displacement during the repair process. When the height of the drone to be repaired varies, rotating the second screw 17 causes the frame 18 to slide along the inside of the limiting frame 16 due to the sliding fit between the outer wall of the frame 18 and the inside of the limiting frame 16. This allows for flexible adjustment of the clamping height of the frame 18 according to the actual height of the drone, adapting to the fixing needs of drones of different sizes and improving the versatility of the device. When further precise fixing of the drone is required, rotating the third screw 19 pushes the fixing pad 110 towards the drone. The fixing pad 110 conforms to the outer contour of the drone, achieving adaptive clamping, which enhances the fixation's firmness and avoids damage to the drone's shell due to excessive clamping force. This structure can stably fix the drone on the top surface of the repair table 3, adapting not only to drones of different heights but also achieving flexible and precise clamping according to the drone's shape, ensuring smooth repair operations.

[0034] Example 2: As Figures 1 to 8 As shown: A drone repair device, including a repair station 3; Fixing unit 1 is placed on the top surface of maintenance table 3. Fixing unit 1 includes a placement tray 11. A first screw 12 is rotatably connected to the bottom of the placement tray 11. A sleeve block 13 is sleeved on the outer wall of the first screw 12. A connecting plate 14 is hinged to the inner side of the sleeve block 13. A limiting block 15 is hinged to the end of the connecting plate 14 away from the sleeve block 13. A limiting frame 16 is connected to the top surface of the limiting block 15. A second screw 17 is rotatably connected inside the limiting frame 16. A retaining frame 18 is sleeved on the outer wall of the second screw 17. A third screw 19 is fitted at the end of the card frame 18, and a fixing pad 110 is connected to the end of the third screw 19; Rotating unit 2 is located outside of fixed unit 1.

[0035] The placement tray 11 has a groove inside, and the outer wall of the limiting block 15 is slidably set with the groove inside the placement tray 11. Under its restriction, the rotating first screw 12 can drive the sleeve block 13 to move up and down, causing the sleeve block 13 to pull the limiting block 15 through the connecting plate 14, so that the limiting block 15 slides inside the placement tray 11.

[0036] There are two card frames 18, which are symmetrically distributed around the center of the placement disk 11. Under the constraint of the two opposing moving card frames 18, the drone can be clamped in an external card sleeve manner.

[0037] The fixing pad 110 is made of rubber and is placed inside the frame 18. Under the constraint of the rubber fixing pad 110, the friction coefficient between the fixing pad 110 and the drone can be increased, while avoiding scratching the surface of the drone.

[0038] The rotating unit 2 includes a groove 21 formed on the top surface of the maintenance table 3, and a limiting ring 22 is slidably provided inside the groove 21; The bottom of the maintenance table 3 is connected to a fixed rod 23, the end of the fixed rod 23 is connected to a first magnetic ring 24, a sliding sleeve 25 is slidably provided on the outer wall of the fixed rod 23, the bottom of the sliding sleeve 25 is connected to a second magnetic ring 26, the outer wall of the sliding sleeve 25 is connected to a ring 27, and a retaining ring 28 is fitted inside the ring 27.

[0039] The top surface of the retaining ring 28 is connected to the bottom of the placement plate 11, and the inside of the limiting ring 22 is fitted with the outer wall of the placement plate 11. Under the restriction of the limiting ring 22, the placement plate 11 can rotate stably in the ring groove 21 opened inside the maintenance table 3. Under the restriction of the retaining ring 28 and the ring sleeve 27, the placement plate 11 after rotation adjustment can be positioned.

[0040] The first magnetic ring 24 and the second magnetic ring 26 are magnetically repulsive. The interior of the second magnetic ring 26 is slidably disposed with respect to the outer wall of the fixing rod 23. Under the restriction of magnetic repulsion, the loop 27 and the retaining ring 28 can be stably engaged, preventing the placement plate 11 from rotating inside the ring groove 21.

[0041] In this embodiment, when the UAV is being repaired, it is stably fixed to the top surface of the repair platform 3 by the fixing unit 1, providing a solid support foundation for subsequent repair operations. When other parts of the UAV need to be repaired, to avoid repeated clamping operations, the loop 27 is pulled down, and the sliding sleeve 25 fixedly installed on the outer wall of the loop 27 slides down synchronously along the outer wall of the fixing rod 23, so that the loop 27 and the retaining ring 28 fixedly installed at the bottom of the placement plate 11 are released from the retaining ring engagement; then the placement plate 11 is rotated, and the limiting ring 22 fixedly sleeved on the outer wall of the placement plate 11 rotates smoothly along the inside of the ring groove 21, thereby driving the fixed UAV to adjust its orientation synchronously. This rotation method can ensure that the position of the UAV does not shift during the adjustment process, improving the accuracy of orientation adjustment. Once the drone is positioned for inspection, the loop 27 is released. Under the magnetic repulsion of the first magnetic ring 24 and the second magnetic ring 26, the first magnetic ring 24 exerts a resetting force on the second magnetic ring 26. The second magnetic ring 26 then drives the sliding sleeve 25 and the loop 27 upwards, causing the loop 27 to re-engage with the retaining ring 28, thus locking the placement tray 11 and fixing the drone's position. This structure allows the fixed drone to have flexible rotation and adjustment capabilities, enabling multi-part inspections without repeated clamping. This simplifies the maintenance process, improves efficiency, and effectively avoids secondary damage to the drone during reassembly.

[0042] The above are merely illustrative embodiments of the present invention and are not intended to limit the scope of the invention. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of the present invention should fall within the scope of protection of the present invention. Furthermore, it should be noted that the components of the present invention are not limited to the overall application described above. Each technical feature described in the specification can be used individually or in combination as needed. Therefore, the present invention naturally covers other combinations and specific applications related to the inventive points of this case.
