Description

Technical Field

[0001] The present application relates to the field of drones, and in particular to a teaching platform for simulating actual flight of drones. Background Art

[0002] A drone is an unmanned aircraft controlled by a radio remote control device and a self-contained program control device, or operated completely or intermittently autonomously by an onboard computer. Drones can be divided into military and civilian applications according to their application areas. In the military, drones are divided into reconnaissance aircraft and target aircraft. In the civilian application area, drones and industry applications are the real rigid demand for drones; currently, drones are used in aerial photography, agriculture, plant protection, micro selfies, express delivery, disaster relief, wildlife observation, infectious disease monitoring, surveying and mapping, news reporting, power inspections, disaster relief, film and television shooting, creating romance, etc., which greatly expands the use of drones themselves. Developed countries are also actively expanding industry applications and developing drone technology.

[0003] Most existing drones have built-in radar infrared automatic obstacle avoidance functions, but the ability to manually operate the drone to avoid obstacles is also necessary for a qualified drone operator. Due to the high cost of drones, it is best to use a teaching platform that can simulate the actual flight of drones for drone obstacle avoidance training. However, the drone simulation teaching devices currently available on the market usually only simulate the different states of the drone during flight and cannot provide targeted obstacle avoidance training for drone operators.

[0004] In the process of implementing this application, the inventors found that there are at least the following problems in this technology: the drone simulation teaching devices currently available on the market usually only simulate the different states of the drone during flight and are unable to provide targeted obstacle avoidance training for drone operators. Therefore, a teaching platform that simulates the actual flight of the drone is now proposed. Utility Model Content

[0005] In order to improve the problem that the existing drone simulation teaching devices on the market usually only simulate the different states of the drone during flight and cannot provide targeted obstacle avoidance training for drone operators, the present application provides a teaching platform that simulates the actual flight of the drone.

[0006] This application provides a teaching platform for simulating the actual flight of drones, using the following technical solutions:

[0007] A teaching platform for simulating the actual flight of a drone comprises a work box, a top plate is arranged above the work box, a multi-degree-of-freedom mobile structure is arranged on the lower surface of the top plate, and a drone simulation structure is fixedly connected to the bottom end of the multi-degree-of-freedom mobile structure;

[0008] The inner bottom wall of the working box is evenly provided with active flight obstacle cylinders, the interior of the active flight obstacle cylinder is slidably connected with an active obstacle, the inner bottom wall of the active flight obstacle cylinder is fixedly connected with a lifting component that drives the active obstacle to rise and fall, the active obstacle is provided with a ranging component, and a plurality of auxiliary flight obstacle cylinders are arranged in a ring around the active flight obstacle cylinder on the lower surface of the working box, the interior of the auxiliary flight obstacle cylinder is slidably connected with an auxiliary obstacle, and when the UAV simulation structure approaches the active obstacle, the lifting component drives the active obstacle to descend, and the auxiliary obstacle to rise at the same time.

[0009] In summary, this application has the following beneficial effects:

[0010] 1. This application cooperates with a work box, a top plate, a multi-degree-of-freedom mobile structure, a second threaded rod, a UAV simulation structure, an active flight obstacle cylinder, an active obstacle, a lifting component and a control console. When in use, the multi-degree-of-freedom mobile structure drives the UAV flight simulation structure to follow the simulation handle to rise and fall, and simulates the rise and fall, movement and posture of the UAV in reality following the handle, and at the same time enables the operator to more intuitively learn the relationship between the UAV wings and the flight of the UAV itself in reality. Before starting teaching, the staff can adjust the height of each lifting component separately through the control console to make the environment simulated by the device more varied. Then the operator controls the UAV simulation structure to conduct obstacle avoidance training for actual UAV flight, so that the device can achieve good targeted obstacle avoidance training and teaching effects.

[0011] 2. In the present application, through the cooperation of the active flight obstacle cylinder, the active obstacle, the lifting assembly, the ranging assembly, the auxiliary flight obstacle cylinder, the auxiliary obstacle, the first piston, the second piston, the solenoid valve and the control console, when the operator accidentally operates the UAV simulation structure to move to collide with the active obstacle, the lifting assembly drives the first piston to descend (squeezes the air below the first piston inside the active flight obstacle cylinder to the auxiliary flight obstacle cylinder), thereby moving the auxiliary obstacle and the second piston upward, thereby increasing the obstacle density around the UAV simulation structure (penalty mechanism), thereby increasing the operating difficulty of the operator and improving the training effect as much as possible. The staff can also first open the solenoid valve through the control console, and then control the lifting assembly to directly drive the active obstacle to rise and close the solenoid valve after the active obstacle rises, and then drive the active obstacle to descend through the lifting assembly (squeezes the air below the first piston inside the active flight obstacle cylinder to the auxiliary flight obstacle cylinder), thereby directly raising the auxiliary obstacle and the second piston, thereby increasing the overall obstacle density inside the device, thereby increasing the training difficulty as much as possible, and improving the training and teaching effect of the device.

[0018] The following is combined with Figure 1-6 Please refer to the following for further details of this application. Figure 1 , Figure 2 and Figure 3 A teaching platform for simulating the actual flight of a drone includes a work box 1 (the work box 1 has a certain height from the ground), a top plate 2 is arranged above the work box 1, and a multi-degree-of-freedom mobile structure 3 is arranged on the lower surface of the top plate 2. The multi-degree-of-freedom mobile structure 3 includes a first motor 301 fixedly connected to both sides of the lower surface of the top plate 2, the output ends of the first motor 301 are fixedly connected to a first threaded rod 302, and the outer side walls of the first threaded rod 302 are sleeved with a first threaded sleeve 303 matched with the first threaded rod 302.

[0019] Reference Figure 2 , Figure 3 and Figure 4When in use, the first motor 301 can drive the first threaded rod 302 to rotate, and then drive the first threaded sleeve 303 to move along the direction of the first threaded rod 302, wherein the bottom end of one of the first threaded sleeves 303 is fixedly connected to the second motor 304 (the second motor 304 and the first motor 301 are arranged vertically in the horizontal direction), the output end of the second motor 304 is fixedly connected to the second threaded rod 305, and the end of the second threaded rod 305 away from the second motor 304 is rotatably connected to the outer side wall of another first threaded sleeve 303, the outer side wall of the second threaded rod 305 is sleeved with a second threaded sleeve 306 that is compatible with the second threaded rod 305, the bottom end of the second threaded sleeve 306 is fixedly connected to the height control electric cylinder 307, and the drone simulation structure 4 is fixed Connected to the output end of the height control electric cylinder 307, the second motor 304 can drive the second threaded rod 305 to rotate, thereby driving the second threaded sleeve 306, the height control electric cylinder 307 and the drone simulation structure 4 to move along the direction of the second threaded rod 305 (the height control electric cylinder 307 can lift the drone simulation structure 4, thereby simulating the lifting of the drone in reality), the bottom end of the multi-degree-of-freedom mobile structure 3 is fixedly connected to the drone simulation structure 4, and the drone simulation structure 4 includes a third motor 401 fixedly connected to the output end of the height control electric cylinder 307, the output end of the third motor 401 is fixedly connected to the connecting plate 402, and the micro electric cylinders 403 (the number of micro electric cylinders 403) are evenly arranged around the lower surface of the connecting plate 402 The output end of the micro-electric cylinder 403 is rotatably connected to the drone model 404 (the output end of the micro-electric cylinder 403 is rotatably connected to the drone model 404 via a ball joint connection). The rotation of the third motor 401 can drive the drone model 404 to turn, thereby simulating the turning of the drone in reality. When the drone moves to one side, the micro-electric cylinder 403 drives the drone model 404 to tilt in the direction of movement, simulating the tilt generated during the movement of the drone in reality. The outer wall of the drone model 404 is fixedly connected to an inlay ring 405, and the outer wall of the inlay ring 405 is evenly embedded with external magnets 406 (the external magnets 406 are embedded with the same poles facing inward). The drone model 404 is inlaid in the inlay circle 405, and an indicator light 407 is arranged above the wing. A control panel (not shown) is electrically connected between the indicator light 407 and the simulation handle. The control panel can change the color and brightness of the indicator light 407 according to the operation sent by the simulation handle. (The two diagonal indicator lights 407 are of the same color, and the rotation speed of the drone wing in reality is simulated by different brightness. For example, when the drone model 404 is stationary to simulate the hovering of the drone in reality, the two diagonal groups of indicator lights 407 are blue and red respectively to indicate different rotation directions, and the same brightness is used to indicate the same wing rotation speed. When the drone model 404 moves, the brightness of the two indicator lights 407 in the opposite direction of movement increases.The two indicator lights 407 with the same moving direction have lower brightness, indicating that the speed is reduced. When the drone model 404 turns, the brightness of one set of diagonal indicator lights 407 increases, and the brightness of the other set of diagonal indicator lights 407 decreases. The different colors and brightness of the indicator lights 407 can make the operator more intuitively learn the relationship between the wings of the drone and the flight of the drone itself in reality.

[0020] Reference Figure 2 , Figure 5 and Figure 6The inner bottom wall of the working box 1 is evenly provided with active flight obstacle cylinders 5, and the active obstacle 6 is slidably connected inside the active flight obstacle cylinder 5. The inner bottom wall of the active flight obstacle cylinder 5 is fixedly connected with a lifting component 7 for driving the active obstacle 6 to be lifted and lowered. A control console 14 for individually controlling the lifting and lowering of each lifting component 7 is provided on one side of the outer wall of the working box 1 (a control panel is electrically connected between the control console 14 and the lifting component 7). The staff can individually adjust the height of each lifting component 7 through the control console 14, so that the environment simulated by the device is more varied. A distance measuring component 8 is provided inside the active obstacle 6, and the distance measuring component 8 includes a slot 801 opened inside the active obstacle 6, and a distance sensor 80 is fixedly connected to the inner top wall of the slot 801. 2. The inner wall of the slot 801 is provided with inclined slots 803 all around, and the inner part of the inclined slot 803 is slidably connected with the inner magnet 804 (the magnetic pole of the inner magnet 804 facing away from the slot 801 is the same as the magnetic pole of the outer magnet 406 facing away from the inlay ring 405, and the magnetic force of the inner magnet 804 is smaller than that of the outer magnet 406, thereby avoiding as much as possible the repulsive force between a group of inner magnets 804 being greater than the repulsive force between the outer magnet 406 and the inner magnet 804 close to the outer magnet 406, resulting in the outer magnet 406 being unable to push the inner magnet 804, and the length of the inner magnet 804 being greater than the width of the slot 801, thereby avoiding as much as possible the inner magnet 804 from sliding completely into the slot 801 and completely leaving the inclined slot 803), the lower surface of the working box 1 A plurality of auxiliary flight obstacle cylinders 9 are arranged in a ring around the active flight obstacle cylinder 5. Auxiliary obstacles 10 are slidably connected inside the auxiliary flight obstacle cylinder 9. When the UAV simulation structure 4 approaches the active obstacle 6, the lifting assembly 7 drives the active obstacle 6 to descend, and the auxiliary obstacle 10 rises at the same time. The outer wall of the active obstacle 6 is fixedly connected to a first piston 11, and the first piston 11 is slidably connected to the active flight obstacle cylinder 5. The auxiliary flight obstacle cylinder 9 is connected to the active flight obstacle cylinder 5. The outer wall of the auxiliary obstacle 10 is fixedly connected to a second piston 12, and the second piston 12 is slidably connected to the auxiliary flight obstacle cylinder 9 (the space above the first piston 11 inside the active flight obstacle cylinder 5 and the space above the second piston 12 inside the auxiliary flight obstacle cylinder 9 are both The working box 1 is located below the active flight obstacle cylinder 5 and is provided with a solenoid valve 13 connected to the active flight obstacle cylinder 5 (a control panel is electrically connected between the solenoid valve 13 and the distance sensor 802, between the lifting assembly 7 and the distance sensor 802, and between the solenoid valve 13 and the control console 14). When the device is in use, the UAV model 404 should maintain a safe distance from the active obstacle 6 during the normal obstacle avoidance teaching simulation. When the operator accidentally operates the UAV model 404 to move to the point where it is about to collide with the active obstacle 6 (breaking the safe distance between the two), the inner magnet 804 is subjected to the magnetic repulsion force from the outer magnet 406 (like poles repel each other), and then moves along the inclined slide groove 803 toward the direction of the slot 801.After the distance sensor 802 senses the spatial change inside the slot 801, the solenoid valve 13 is closed (the space inside the active flight obstacle cylinder 5 below the first piston 11 is closed). When the inner magnet 804 is no longer affected by the magnetic repulsion of the outer magnet 406, the inner magnet 804 is reset along the inclined slide groove 803, and the lifting assembly 7 drives the first piston 11 downward (squeezing the air inside the active flight obstacle cylinder 5 below the first piston 11 into the auxiliary flight obstacle cylinder 9), thereby moving the auxiliary obstacle 10 and the second piston 12 upward. The distance between the auxiliary obstacle 10 and the active obstacle 6 and the distance between two adjacent auxiliary obstacles 10 are both greater than the sum of the width and the safety distance range of the drone simulation mechanism 4 (to avoid collision between the auxiliary obstacle 10 and the drone model 404 when the distance between the drone model 404 and the active obstacle 6 is less than the safety distance due to the small distance between the active obstacle 6 and the auxiliary obstacle 10).

[0021] The implementation principle of the present application is as follows: before starting teaching, the staff can use the console 14 to individually adjust the height of each lifting component 7, so that the environment simulated by the device is more varied. When in use, the first motor 301 can drive the first threaded rod 302 to rotate, thereby driving the first threaded sleeve 303 to move along the direction of the first threaded rod 302. The second motor 304 can drive the second threaded rod 305 to rotate, thereby driving the second threaded sleeve 306, the height control electric cylinder 307 and the drone simulation structure 4 to move along the direction of the second threaded rod 305 (the height control electric cylinder 307 can lift the drone simulation structure 4, thereby simulating the lifting of the drone in reality). The rotation of the third motor 401 can drive The drone model 404 turns (simulating the turning of the drone in reality). When the drone moves to one side, the micro electric cylinder 403 drives the drone model 404 to tilt in the direction of movement (simulating the tilt generated during the movement of the drone in reality). Then, the operator holds a simulated handle (not numbered in the figure) that is the same as the drone operating handle in reality, and drives the drone model 404 to move up and down following the simulated handle through the cooperation between the first motor 301, the first threaded rod 302, the first threaded sleeve 303, the second motor 304, the second threaded rod 305, the second threaded sleeve 306, and the height control electric cylinder 307, simulating the lifting and movement of the drone following the handle in reality (the first motor 301, the second motor 304, the height control electric cylinder 307, the micro electric cylinder 403 and the third motor 401 are all electrically connected to the simulation handle). At the same time, a control panel (not shown in the figure) is electrically connected between the indicator light 407 and the simulation handle. The control panel can change the color and brightness of the indicator light 407 according to the operation sent by the simulation handle. The indicator light 407 set above the wing of the drone demonstrates the rotation direction and rotation speed of the wing of the drone in reality. (The two diagonal indicator lights 407 are of the same color and simulate the rotation speed of the wing of the drone in reality through different brightness. For example, when the drone model 404 is stationary to simulate the hovering of the drone in reality, the two diagonal groups of indicator lights 407 are blue and red respectively to indicate that the rotation direction is not The same, and the same brightness is used to indicate that the wing rotation speed is the same. When the drone model 404 moves, the brightness of the two indicator lights 407 in the opposite direction of movement increases, indicating that the rotation speed increases, and the brightness of the two indicator lights 407 in the same direction of movement decreases, indicating that the rotation speed decreases. When the drone model 404 turns, the brightness of one group of diagonal indicator lights 407 increases, and the brightness of the other group of diagonal indicator lights 407 decreases). Through the different colors and brightness of the indicator lights 407, the operator can more intuitively learn the relationship between the drone wing and the flight of the drone itself in reality. When the operator accidentally operates the drone model 404 to move to the point where it is about to collide with the active obstacle 6, the inner magnet 804 is subjected to the magnetic repulsion force from the outer magnet 406 (like poles repel each other).Then, the slidable air flow path 803 moves toward the slot 801. After the distance sensor 802 senses the space change inside the slot 801, the solenoid valve 13 is closed (the space below the first piston 11 inside the active flight obstacle cylinder 5 is closed), and the lifting assembly 7 drives the first piston 11 to descend (squeezing the air below the first piston 11 inside the active flight obstacle cylinder 5 into the auxiliary flight obstacle cylinder 9), thereby moving the auxiliary obstacle 10 and the second piston 12 upward, thereby preventing the UAV model 404 from directly colliding with the active obstacle 6 as much as possible, and improving the air flow around the UAV model 404. The obstacle density (penalty mechanism) increases the difficulty of operation for the operator. The staff can also first open the solenoid valve 13 through the console 14, and then operate the lifting assembly 7 to directly drive the active obstacle 6 to rise and close the solenoid valve 13 after the active obstacle 6 rises, and then drive the active obstacle 6 down through the lifting assembly 7 (squeezing the air below the first piston 11 inside the active flight obstacle cylinder 5 into the auxiliary flight obstacle cylinder 9), thereby directly raising the auxiliary obstacle 10 and the second piston 12, thereby increasing the overall obstacle density inside the device, thereby increasing the training difficulty as much as possible, and improving the training and teaching effect of the device.

[0022] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
