Description

Technical Field

[0001] The present invention relates to the technical field of UAV production and processing, and specifically relates to a UAV rotation balance detection device. Background Art

[0002] A UAV is an aircraft that does not require direct human piloting and control. By using advanced remote control technology, autonomous flight control systems, and sensor technology, it can perform various tasks in the air, such as taking pictures and videos, transporting goods, etc. During the production and manufacturing process of UAVs, they usually need to be tested to check whether their various performances are qualified. Among them, the rotation balance of UAVs is one of the important links in the testing process; Currently, during the transportation of UAVs with loaded goods, when the goods are placed, due to the inconsistency between the center of gravity of the goods and the center of gravity of the UAV, and when the UAV ascends into the air with loaded goods, the goods may be affected by wind force, which may cause the UAV to tilt, resulting in an imbalance of the entire UAV. The existing UAV rotation balance detection devices cannot detect the magnitude of the rotation balance of UAVs under different degrees of gravity deviation (i.e., when different unbalanced loads act), leading to the UAV being prone to instability or out-of-control during actual flight, thereby affecting the stability and flight performance of the UAV. Summary of the Invention

[0003] In view of this, in response to the deficiencies of the prior art, the present invention provides a UAV rotation balance detection device to solve the problem in the prior art that the magnitude of the rotation balance of UAVs under different degrees of gravity deviation cannot be detected, which affects the stability and flight performance of UAVs.

[0004] To achieve the above object, the present invention provides the following technical solution: A UAV rotation balance detection device includes a detection box. One side of the detection box is hinged with a box door, and two operation doors are symmetrically hinged to the detection box. Four limit sliding rails are provided on the detection box, and support seats are slidably connected in the four limit sliding rails. Four connecting seats are symmetrically and fixedly connected to the bottom of the inner cavity of the detection box. A winding wheel is rotatably connected to each of the four connecting seats through a rotating shaft. A traction rope is wound around the outer surface of the winding wheel. One end of the traction rope is fixedly connected to the winding wheel, and the end of the traction rope far from the winding wheel is fixedly connected with a buckle. A conical groove is formed on one side of the winding wheel close to the operation door. A friction column is threadedly connected to one side of the connecting seat close to the conical groove. A limit hole is formed on the friction column, and the limit hole is adapted to the rotating shaft on the connecting seat. A rotating handle is fixedly connected to the side of the friction column far from the connecting seat; A reminder mechanism is provided on the support base. The reminder mechanism includes an installation groove. An installation groove is formed at the bottom of the support base. A trigger post is slidably connected inside the installation groove. A pressing block is fixedly connected to the bottom of the trigger post. A touch switch is fixedly connected to the bottom of the inner cavity of the installation groove. The touch switch is located on the movement track of the pressing block. The trigger post is integrally in an I shape. Magnets I are fixedly connected to both the upper surface of the bottom of the trigger post and the top of the installation groove. The magnet I on the installation groove and the magnet I on the trigger post are magnetically attracted to each other. Magnets II are fixedly connected to both the top of the touch switch and the lower surface of the bottom of the trigger post. The magnet II on the touch switch and the magnet II on the trigger post are magnetically repelled from each other. A warning light is fixedly connected to the top of the support base.

[0005] Preferably, an adjustment mechanism is further included. The adjustment mechanism includes sliding grooves. The sliding grooves are symmetrically formed at the top of the inner cavity of the detection box, and there are four sliding grooves. A bidirectional lead screw is rotatably connected jointly in two sliding grooves in the same straight line direction. There are two bidirectional lead screws. The thread directions at both ends of the bidirectional lead screw are opposite. The middle parts of both bidirectional lead screws are rotatably connected to the top of the detection box. A limiting rod is fixedly arranged in each sliding groove. Connecting plates are slidably connected in the four sliding grooves. The connecting plates are threadedly connected to the bidirectional lead screws. The connecting plates are slidably connected to the adjacent limiting rods. Four limiting slide rails are respectively fixedly connected to the bottoms of the four connecting plates.

[0006] Preferably, a rotating handle is fixedly connected to one end of the bidirectional lead screw. The rotating handle is rotatably connected to the detection box.

[0007] Preferably, a buffer mechanism is further included. The buffer mechanism includes a connecting rod. A connecting rod is rotatably connected to the support base, and the connecting rod is located inside the adjacent limiting slide rails. Two pulleys are symmetrically and fixedly connected to the connecting rod. The pulleys are in contact with one inner wall of the limiting slide rails. Two ratchets are symmetrically and fixedly connected to the connecting rod. Two annular cylinders are symmetrically rotatably connected to the support base. The annular cylinders are sleeved on the outer surface of the connecting rod, and the two ratchets are respectively located inside the two annular cylinders. A pawl is rotatably connected to the annular cylinder. The ratchet is adapted to the pawl. A plurality of sliding rods are circumferentially and equidistantly slidably connected to the annular cylinder. A rubber plate is fixedly connected to the end of the sliding rod located outside the annular cylinder.

[0008] Preferably, a return spring is connected between the sliding rod and the inner wall of the annular cylinder. The return spring is sleeved on the outer surface of the sliding rod and is located inside the annular cylinder.

[0009] Compared with the prior art, the present invention has the following beneficial effects: Place the drone on four support bases, and then manually rotate the turning handle by the tester, so that the conical end of the friction column gradually extends into the conical groove and fits with the conical groove, making the contact between the two closer. Thus, the friction between the friction column and the winding wheel is increased, and then the resistance when the winding wheel rotates is increased, thereby increasing the pulling force of the traction rope connected to the winding wheel on the drone. In this way, an unbalanced load on the drone is simulated. Therefore, the traction rope makes the arms at the four corners of the drone in a state of unbalanced load. Then, the tester can observe the tilting state of the drone body when the drone ascends vertically to simulate the situation when the center of gravity of the cargo deviates from the center of gravity of the drone to different degrees during its cargo-carrying flight process, so as to detect the rotational balance of the drone. At the same time, the friction between the four friction columns and the conical groove can be changed to simulate different cargos, and then the size of the rotational balance of the drone under different gravity deviations can be detected.

[0010] Adjust the distance between the support bases by manually rotating the crank handle, so that the fuselage of the drone can be placed on the four support bases. Thus, the distance between the limit sliding rails can be adjusted according to the width of the drone itself, and then drones of different specifications and sizes can be detected, which can improve the applicability and versatility of this detection device. It can also provide limit protection for the drone to avoid falling during detection.

[0011] When the drone tilts, it contacts the trigger post at the bottom of the drone, thus squeezing the trigger post to slide downward and squeezing the touch switch through the abutting block, turning on the warning light. Then, it can quickly attract the attention of the tester, enabling the tester to immediately notice the tilting problem of the drone and helping the tester more accurately judge the balance of the drone, thereby improving the detection efficiency and accuracy.

[0012] When placing the drone in the support base, the reminder mechanism can provide visual feedback to the staff in a timely manner, indicating to the tester that the drone has been placed in place. Then, the situation of safety accidents of the drone caused by misoperation or negligence can be reduced. At the same time, it can also avoid the problem that the tester needs to manually check whether the drone is placed in place, thus improving the overall work efficiency. Description of the Drawings

Specific embodiments

[0015] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0016] Next, the present invention will be further described in detail according to the drawings and embodiments.

[0017] Embodiment 1 of the present invention:

[0018] As Figures 1 to 7 shown, a drone rotation balance detection device includes a detection box 1. It should be noted that, Figure 1Among them, a is the left, b is the right, c is the front, and d is the back. A box door 101 is hinged to the front side of the detection box 1. Two operation doors 102 are symmetrically hinged to the left and right sides of the detection box 1. Both the box door 101 and the operation door 102 are made of transparent materials, so that the inspectors can observe the condition of the drone inside the detection box 1. Four limit sliding rails 2 are arranged on the detection box 1. A support seat 201 is slidably connected to each of the four limit sliding rails 2. A rubber pad is arranged at the contact between the support seat 201 and the limit sliding rail 2 to increase the friction between the support seat 201 and the limit sliding rail 2. When the support seat 201 is not affected by external force factors, the support seat 201 is stable and immovable inside the limit sliding rail 2. Four connecting seats 202 are symmetrically and fixedly connected to the bottom of the inner cavity of the detection box 1. A winding wheel 203 is rotatably connected to each of the four connecting seats 202 through a rotating shaft. A traction rope 204 is wound around the outer surface of the winding wheel 203. One end of the traction rope 204 is fixedly connected to the winding wheel 203. The end of the traction rope 204 far from the winding wheel 203 is fixedly connected with a buckle 205. A conical groove 206 is formed on one side of the winding wheel 203 close to the operation door 102. A friction column 207 is threadedly connected to one side of the connecting seat 202 close to the conical groove 206. The end of the friction column 207 facing the winding wheel 203 is in the shape of a tapered cylinder and corresponds to the shape of the conical groove 206. A limit hole 208 is formed on the friction column 207, and the limit hole 208 is adapted to the rotating shaft on the connecting seat 202. The friction column 207 is sleeved outside the rotating shaft of the connecting seat 202 through the limit hole 208. A rotating handle 209 is fixedly connected to the side of the friction column 207 far from the connecting seat 202, and the rotating handle 209 faces the adjacent operation door 102, so that the inspector can easily control the rotating handle 209.

[0019] Working process: When in use, the tester first opens the box door 101, and then places the fuselage of the drone to be tested on the four support seats 201. After placing it flat, the tester clips the buckle 205 on the towing rope 204 to a position on the drone arm away from the propeller. The four buckles 205 are respectively clipped to the four arms at the four corners. Then, the tester operates the drone to rise uniformly upwards. After the drone rises to abut against the support seat 201, the drone fuselage drives the four support seats 201 to slide upwards along the limit slide rail 2. At the same time, the drone drives the buckle 205 to rise synchronously, causing the towing rope 204 wound on the winding wheel 203 to continuously extend and extend with the drone. During this process, the tester can manually rotate the handle 209 to cause the friction column 207 to continuously move towards the side close to the winding wheel 203, so that the conical end of the friction column 207 gradually extends into the internal part of the conical groove 206 and fits with the conical groove 206, making the contact between the two closer. Thereby, the friction force between the friction column 207 and the winding wheel 203 is increased, and further the resistance when the winding wheel 203 rotates is increased, so as to increase the pulling force of the towing rope 204 connected to the winding wheel 203 on the drone, thereby simulating the unbalanced load received by the drone. Therefore, the towing rope 204 makes the arms at the four corners of the drone in a state of unbalanced load. Furthermore, the tester can observe the tilting state of the drone body when the drone rises vertically, so as to simulate the situation when the center of gravity of the cargo and the center of gravity of the drone deviate to different degrees during its cargo-carrying flight process, thereby detecting the rotational balance of the drone. At the same time, the friction force between the four friction columns 207 and the conical groove 206 can be changed to simulate different cargos, and further the rotational balance of the drone under different gravity deviations (i.e., when different unbalanced loads act) can be detected.

[0020] Embodiment 2 of the present invention:

[0021] Such as Figure 2 、 Figure 3 、 Figure 5 And Figure 6As shown in the figure, an adjusting mechanism is provided inside the detection box 1. The adjusting mechanism includes sliding grooves 3, which are symmetrically opened at the top of the inner cavity of the detection box 1, and there are four sliding grooves 3. A bidirectional lead screw 301 is rotatably connected in common in two sliding grooves 3 in the same straight line direction. There are two bidirectional lead screws 301, and the thread directions at both ends of the bidirectional lead screw 301 are opposite. The middle parts of the two bidirectional lead screws 301 are rotatably connected to the top of the detection box 1. There is a vertical height difference between the two bidirectional lead screws 301. A limiting rod 302 is fixedly arranged in each sliding groove 3. A connecting plate 303 is slidably connected in all four sliding grooves 3. The connecting plate 303 is threadedly connected to the bidirectional lead screw 301, and the connecting plate 303 is slidably connected to the adjacent limiting rod 302. Four limiting slide rails 2 are respectively fixedly connected to the bottoms of the four connecting plates 303, so as to adjust the positions of the limiting slide rails 2. One end of the bidirectional lead screw 301 is fixedly connected with a rotating handle 304, and the rotating handle 304 is rotatably connected to the detection box 1.

[0022] Working process: The tester first manually rotates a rotating handle 304 to make a bidirectional lead screw 301 fixedly connected thereto rotate. During this process, the bidirectional lead screw 301 drives the two connecting plates 303 thereon to move away from each other, and then drives the two limiting slide rails 2 and the support seats 201 to move away from each other, facilitating the adjustment of the distance between the two support seats 201. Then, the other rotating handle 304 is rotated in the same way to adjust the distance between the other two support seats 201, so that the fuselage of the drone can be placed on the four support seats 201. Thus, the distance between the limiting slide rails 2 can be adjusted according to the width of the drone itself, and then drones of different specifications and sizes can be detected, which can improve the applicability and versatility of this detection device, and can also limit and protect the drone to avoid falling during detection.

[0023] Embodiment III of the present invention:

[0024] As Figures 7 to 9As shown, a reminder mechanism is provided on the support base 201. The reminder mechanism includes an installation groove 4. An installation groove 4 is opened at the bottom of the support base 201. A trigger post 401 is slidably connected inside the installation groove 4. A contact block 402 is fixedly connected to the bottom of the trigger post 401. A touch switch 403 is fixedly connected to the bottom of the inner cavity of the installation groove 4. The touch switch 403 is located on the movement track of the contact block 402. The trigger post 401 is integrally in an I shape, so that the trigger post 401 can be restricted in the installation groove 4 to prevent it from detaching. Magnet 1 404 is symmetrically fixedly connected to the upper surface of the bottom of the trigger post 401 and the top of the installation groove 4, and the magnet 1 404 on the installation groove 4 is located on the movement track of the magnet 1 404 on the trigger post 401. The magnet 1 404 on the installation groove 4 and the magnet 1 404 on the trigger post 401 are magnetically attracted to each other. Magnet 2 405 is symmetrically fixedly connected to the top of the touch switch 403 and the lower surface of the bottom of the trigger post 401. The magnet 2 405 on the touch switch 403 and the magnet 2 405 on the trigger post 401 are magnetically repulsive to each other. And the frictional force between the limit slide rail 2 and the support base 201 is greater than the repulsive force between the magnet 2 405 and greater than the magnetic attraction force between the magnet 1 404, so that when the drone squeezes the trigger post 401 and makes it slide into the installation groove 4, the support base 201 and the limit slide rail 2 remain relatively stationary. A warning light 406 is fixedly connected to the outer wall of the top of the support base 201. Both the touch switch 403 and the warning light 406 are electrically connected to an external known controller. The touch switch 403 is used to control the opening and closing of the warning light 406 through the controller.

[0025] Working process: When the tester places the drone in the support base 201, the drone first contacts the trigger post 401. Under the extrusion of its own weight, the trigger post 401 slides into the installation groove 4. During this process, the abutting block 402 at the bottom of the trigger post 401 gradually approaches the touch switch 403, and the magnet one 404 on the trigger post 401 moves away from the magnet one 404 in the installation groove 4. The magnet two 405 at the bottom of the trigger post 401 gradually approaches the magnet two 405 at the top of the touch switch 403. When the abutting block 402 contacts the touch switch 403 and squeezes the touch switch 403 downward, the touch switch 403 turns on the warning light 406 through the controller, making it start to work. Thus, it can provide visual feedback to the staff in a timely manner, indicating to the tester that the drone has been placed in place. Furthermore, it can reduce the occurrence of safety accidents of the drone caused by misoperation or negligence. At the same time, it can also avoid the problem that the tester needs to manually check whether the drone is placed in place, thereby improving the overall work efficiency. When the drone ascends, the drone gradually separates from the trigger post 401. Using the repulsive force between the magnet two 405 and the magnetic attraction force between the magnet one 404, the trigger post 401 slides vertically upward, and the abutting block 402 at the bottom of the trigger post 401 also moves upward and separates from the touch switch 403. At this time, the touch switch 403 returns to its original position, and the warning light 406 is turned off. The trigger post 401 continues to slide upward until the magnet one 404 on the installation groove 4 magnetically adheres to the magnet one 404 on the trigger post 401, and the trigger post 401 returns to its original position. When the drone tilts due to excessive resistance of the traction rope 204 on one side, the bottom of the drone will contact the trigger post 401 again. At this time, the support base 201 and the limit slide rail 2 are in a relatively static state. Similarly, the drone will squeeze the trigger post 401 to slide downward and squeeze the touch switch 403 through the abutting block 402, turning on the warning light 406, and then being able to quickly attract the attention of the tester, enabling the tester to immediately notice the problem of the drone tilting, helping the tester more accurately judge the balance of the drone, and thus improving the efficiency and accuracy of the detection.

[0026] Embodiment 4 of the present invention:

[0027] Such as Figure 9 And Figure 10As shown in the figure, it further includes a buffer mechanism. The buffer mechanism includes a connecting rod 5. The connecting rod 5 is rotatably connected to the support base 201, and the connecting rod 5 is located inside the adjacent limiting slide rail 2. Two pulleys 501 are symmetrically and fixedly connected to the connecting rod 5. The two pulleys 501 are respectively located at both ends of the connecting rod 5, and the pulley 501 is in contact with one inner wall of the limiting slide rail 2. Two ratchets 502 are symmetrically and fixedly connected to the connecting rod 5. Two annular cylinders 503 are symmetrically and rotatably connected to the support base 201. The annular cylinders 503 are sleeved on the outer surface of the connecting rod 5, and the two ratchets 502 are respectively located inside the two annular cylinders 503. A pawl 504 is rotatably connected to the annular cylinder 503. The ratchet 502 is adapted to the pawl 504. A plurality of slide rods 505 are circumferentially and slidably connected to the annular cylinder 503. One end of the slide rod 505 located outside the annular cylinder 503 is fixedly connected with a rubber plate 506. A return spring 507 is connected between the slide rod 505 and the inner wall of the annular cylinder 503. The return spring 507 is sleeved on the outer surface of the slide rod 505, and the return spring 507 is located inside the annular cylinder 503.

[0028] Working process: When the drone drives the support base 201 to slide upward along the limiting slide rail 2, the pulley 501 located inside the limiting slide rail 2 rotates while being in contact with the inner wall of the limiting slide rail 2, and drives the connecting rod 5 and the ratchet 502 to rotate together. At this time, the pawl 504 slides along the ratchet teeth on the outer surface of the ratchet 502, and the two do not engage with each other. The annular cylinder 503 rotatably connected to the support base 201 cannot rotate synchronously therewith, resulting in the plurality of slide rods 505 inside the annular cylinder 503 being in a stationary state. When the drone fails to continue flying due to insufficient battery power or excessive load causing hardware failures, the drone falls downward under its own gravity. The drone pushes the support base 201 to slide rapidly downward along the inside of the limiting slide rail 2, causing the pulley 501 located inside the limiting slide rail 2 to rotate in the reverse direction while being in contact with the inner wall of the limiting slide rail 2. The pulley 501 drives the connecting rod 5 and the ratchet 502 to rotate in the same direction. At this time, the pawl 504 abuts against the ratchet teeth of the ratchet 502, and the two engage with each other. Therefore, the annular cylinder 503 can rotate synchronously with the connecting rod 5, resulting in the plurality of slide rods 505 inside the annular cylinder 503 also rotating therewith. As the annular cylinder 503 rotates, the plurality of slide rods 505 inside the annular cylinder 503 are gradually thrown out to the outside of the annular cylinder 503 by the rotating force. The rubber plates 506 on the plurality of slide rods 505 gradually approach and contact the inner wall of the limiting slide rail 2, and the rubber plates 506 are used to increase the friction with the inner wall of the limiting slide rail 2. Thus, the speed of the support base 201 sliding downward along the limiting slide rail 2 can be slowed down, and the impact force of the drone hitting an object can be reduced, thereby reducing the damage degree of the drone and reducing the damage rate of the drone during the detection process.

[0029] The above has introduced the present application in detail. Specific examples are used in this text to elaborate on the principle and implementation manner of the present application. The description of the above embodiments is only used to help understand the method and its core idea of the present application; at the same time, for those of ordinary skill in the art, according to the idea of the present application, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present application.
