Description

Technical Field

[0001] This utility model relates to the field of lift measurement technology, and in particular to a lift measurement device for a multifunctional unmanned aerial vehicle. Background Technology

[0002] Unmanned aerial vehicle (UAV) lift testing involves measuring and evaluating the lift performance of an UAV under different conditions to ensure its flight stability and safety. It mainly tests parameters such as the maximum lift, minimum lift, and lift efficiency of the UAV, while also verifying its lift adaptability in extreme environments such as high altitude and low temperature.

[0003] In traditional unmanned aerial vehicle (UAV) lift performance testing, operators typically manually install measuring devices beneath the aircraft. During testing, operator error or system malfunction can cause the aircraft to crash, potentially damaging the equipment and endangering nearby personnel due to flying structural components. Current testing methods lack effective real-time protection, making it difficult to provide reliable protection for the aircraft and personnel in emergencies. Furthermore, critical protective components such as buffer pads and load-bearing connectors are prone to wear and aging during long-term, repeated use, and existing equipment often does not support rapid replacement, leading to gradual failure of protective functions and increasing the risk of safety accidents. Therefore, this application provides a multifunctional lift measurement device for UAVs to meet these needs. Utility Model Content

[0026] like Figures 1 to 9As shown, an embodiment of this utility model provides a multifunctional lift measurement device for unmanned aerial vehicles, including a test base plate 1. A support rod 2 is inserted into the upper surface of the test base plate 1, and a sliding assembly 3 is inserted into one side of the support rod 2. The sliding assembly 3 includes a movable slide rail 301, a movable motor 302, a movable lead screw 303, and a movable bearing 304. The movable motor 302 is inserted into the inner bottom of the movable slide rail 301, and the movable lead screw 303 is inserted into one end of the movable motor 302. The movable bearing 304 is sleeved on one end of the movable lead screw 303. A bearing groove is formed in the inner top of the movable slide rail 301, and the movable bearing 304 is inserted into the inside of the bearing groove. The internal sliding connection includes a movable slider 7, through which a movable lead screw 303 passes. A support push rod 4 is inserted into the support rod 2. The support push rod 4 is an electric push rod, also known as a linear actuator, mainly composed of a motor push rod and control devices, and can be considered a structural extension of a rotary motor. A tension sensor 5 is inserted into the upper surface of the test base plate 1. A tension wire 501 is provided on one side of the tension sensor 5, and a connector 502 is provided on one side of the tension wire 501. A tension threaded hole is opened on the upper surface of the tension sensor 5. A test assembly 6 is provided on the upper surface of the tension sensor 5. 6 includes a test rope 601, a test hook 602, a test nut 603, and a test threaded post 604. One end of the test rope 601 is inserted into the test hook 602, and the other end is inserted into the test nut 603. The lower surface of the test nut 603 is fitted with the test threaded post 604. A sliding block 7 is slidably connected inside the sliding assembly 3. A protective plate 8 is sleeved on one end of the support push rod 4. Protective threaded holes are formed at the four corners of the upper surface of the protective plate 8. A push rod threaded hole is formed on the upper surface of the support push rod 4. The support push rod 4 is mounted on the lower surface of the protective plate 8 via a protective bolt 401. A protective tube 9 is inserted inside the protective plate 8. The upper surface of the protective plate 8... A protective hole is provided in the center, and a protective tube 9 is inserted into the protective hole. The upper surface of the protective plate 8 is provided with a protective velvet surface 10, the upper surface of the protective velvet surface 10 is provided with a protective hook surface 11, the upper surface of the protective hook surface 11 is provided with a protective pad 12, the upper surface of the support rod 2 is provided with a support groove, and a support push rod 4 is inserted into the support groove. The center of the upper surface of the protective pad 12 is provided with a docking hole, and the upper surface of the protective pad 12 is provided with a test aircraft 13. A protective cover 14 is fitted onto one side of the movable slider 7, and a test controller 15 is inserted into one side of the protective cover 14. The upper surface of the movable slider 7 is provided with a slider thread hole, and four movable sliders 7 are provided on both sides of the inner wall of the protective cover 14.

[0027] The protective pad 12 is fixed to the protective plate 8 by attaching the protective felt 10 on the protective plate 8 to the protective hook surface 11 under the protective pad 12. The test hook 602 on the test rope 601 is passed through the docking hole on the protective pad 12 and connected to the test aircraft 13. After the test aircraft 13 is connected, the moving motor 302 drives the moving screw 303 to rotate, causing the protective cover 14 to move upward on the moving slide rail 301 on the test base plate 1 for protection. The test controller 15 is connected to the connector 502 on one side of the tension sensor 5. The test aircraft 13 rises and drives the test... The test rope 601 is raised, causing the tension sensor 5 to sense the lift of the test aircraft 13. The tension sensor 5 feeds back the value to the test controller 15 for processing through the tension wire 501. This allows personnel to know the lift of the test aircraft 13 through the test controller 15. Personnel can quickly know the lift of the test aircraft 13. The protective cover 14 and protective pad 12 can quickly protect the test aircraft 13 and personnel, reducing the risk of the test rope 601 breaking due to prolonged use during testing, which could cause the test aircraft 13 to fall onto the protective plate 8 and be damaged, or cause personnel injury due to flying parts when the test aircraft 13 falls.

[0028] During testing, after the test aircraft 13 fell and damaged the protective pad 12, the moving motor 302 drove the moving screw 303 to rotate, causing the protective cover 14 to move downwards on the moving slide rail 301 on the test base plate 1. The protective felt 10 on the protective plate 8 then adhered to the protective hook surface 11 under the protective pad 12, allowing for quick installation and removal of the protective pad 12 on the protective plate 8. During testing, if the test rope 601 broke due to prolonged use, the moving motor 302 would drive the moving screw 303 to rotate, causing the protective cover 14 to move downwards on the moving slide rail 301 on the test base plate 1. Move upwards on 01, and remove the test threaded post 604 from the tension sensor 5 by rotating the test nut 603. After removal, replace the test rope 601, and then install the test threaded post 604 back into the tension sensor 5 by rotating the test nut 603. This allows for quick replacement of the protective pad 12 and the test rope 601 inside the equipment, effectively reducing protection failures or safety accidents caused by wear during use, thus ensuring the safety and continuity of subsequent tests.

[0029] The working principle of the technical solution provided by this utility model is as follows: During testing, the protective felt 10 on the protective plate 8 is pasted to the protective hook surface 11 under the protective pad 12, thus fixing the protective pad 12 to the protective plate 8. The test hook 602 on the test rope 601 is passed through the docking hole on the protective pad 12 and connected to the test aircraft 13. After the test aircraft 13 is connected, the moving motor 302 drives the moving screw 303 to rotate, causing the protective cover 14 to move upward on the moving slide rail 301 on the test base plate 1 for protection. The connection is achieved through the connector on one side of the tension sensor 5. 502 is connected to the test controller 15. The test aircraft 13 ascends, causing the test rope 601 to move upwards. This allows the tension sensor 5 to sense the lift of the test aircraft 13. The tension sensor 5 then feeds the value back to the test controller 15 via the tension wire 501 for processing. Personnel can then quickly ascertain the lift of the test aircraft 13 through the test controller 15. The protective cover 14 and protective pad 12 provide rapid protection for both the test aircraft 13 and personnel, reducing the risk of the test rope 601 breaking due to prolonged use during testing. This resulted in the test aircraft 13 falling onto the protective plate 8 and being damaged, and the flying parts of the test aircraft 13 causing injuries. During the test, after the test aircraft 13 fell and damaged the protective pad 12, the moving motor 302 drove the moving screw 303 to rotate, causing the protective cover 14 to move downwards on the moving slide rail 301 on the test base plate 1. The protective felt 10 on the protective plate 8 adhered to the protective hook surface 11 under the protective pad 12, allowing for quick installation and removal of the protective pad 12 on the protective plate 8. During the test, the test rope 601 broke due to prolonged use, and the moving motor... The machine 302 drives the movable lead screw 303 to rotate, causing the protective cover 14 to move upward on the movable slide rail 301 on the test base plate 1. By rotating the test nut 603, the test threaded post 604 is removed from the tension threaded hole on the tension sensor 5. After removal, the test rope 601 is replaced, and then the test nut 603 is rotated again to install the test threaded post 604 into the tension threaded hole on the tension sensor 5. This effectively reduces the protection failure or safety accidents caused by wear of both during use, thereby ensuring the safety and continuity of subsequent tests.
