Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicle detection, and in particular to a unmanned aerial vehicle power detection device and a use method thereof. Background Art

[0002] The performance of the power system directly affects the flight performance of the drone. Testing the power output of the motor can ensure that the drone can obtain sufficient lift and thrust. For example, in a load test, measuring the thrust generated by the propeller can ensure that the drone can still take off, hover and fly normally when carrying equipment of a certain weight (such as a camera used for mapping).

[0003] Accurate power output is also very important for the flight attitude control of the UAV. Power testing can find out whether the power system can respond to the instructions of the flight control system in a timely manner to ensure the stability and accuracy of the UAV during turns, pitches, rolls and other actions. For example, when the UAV needs to turn quickly, the power system needs to provide sufficient power to achieve this action. Power testing can ensure that the power system has such capabilities.

[0004] The power detection device in the prior art relies on sensors to obtain the power of the drone, but the cost of the sensors is relatively high, which is not conducive to large-scale production and popularization, or it needs to rely on fans for transmission and judge the power of the drone by calculating the fan speed. However, the fan itself has a certain inertia during the rotation process, which may interfere with the accuracy of the power data. At the same time, its calculation process is also relatively cumbersome and time-consuming, and there are certain limitations.

[0005] In view of this, this application is hereby filed. Summary of the invention

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] See also Figure 1-7 , the present invention provides a technical solution:

[0036] A drone power detection device and a method for using the same, comprising a base 1, a placement plate 2, and a connecting column 3. The bottom surface of the placement plate 2 is rotatably connected to an adjustment plate 4. A lever 401 is provided on one side of the adjustment plate 4. The other end of the lever 401 is connected to one end of an elastic band 402. The other end of the elastic band 402 passes through the top surface of the placement plate 2. A tension spring 5 is provided between the other side of the adjustment plate 4 and the placement plate 2.

[0037] By adopting the above design, when conducting a power test on a UAV, the elastic band 402 can be wrapped around the base 1 of the UAV, and then the UAV can be started to drive the adjustment plate 4 to rotate. Whether there is sufficient power can be determined by whether the elastic force of the tension spring 5 can be overcome. In addition, there is a resistance arm lever 401 between the adjustment plate 4 and the lever 401, which can convert the smaller elastic force of the tension spring 5 into a larger resistance, so that the device does not need to customize a special tension spring 5 during manufacturing, making the use and production of the device convenient.

[0038] Furthermore, a slide groove is opened in the adjustment plate 4, and an adjustment block 6 is slidably connected in the slide groove. A threaded adjustment column 601 is rotatably connected in the adjustment plate 4, and the threaded adjustment column 601 is threadedly connected to the adjustment block 6. The adjustment block 6 and the bottom surface of the placement plate 2 are both provided with pull rings 602, and the two ends of the tension spring 5 are placed on the pull rings 602.

[0039] By adopting the above design, when in use, according to different models of drones, the adjustment block 6 can be driven to rise and fall by rotating the threaded adjustment column 601, and the proportion of the lever 401 of the resistance arm can be adjusted to meet the power test requirements of drones of different models. In addition, if the power test requirement of the drone to be tested is too large or too small, the two ends of the tension spring 5 can be pulled out from the pull ring 602 to replace the tension spring 5, and the adjustable range of the tension spring 5 can be changed, thereby improving the versatility and practicality of the device.

[0040] Furthermore, there are a plurality of adjustment plates 4 distributed at intervals in a circular array.

[0041] By adopting the above design, when testing, the elastic band 402 can be tied to different arms of the drone, and the multiple arms of the drone can be tested separately, so as to more accurately determine whether the parameters of a certain arm among the multiple arms are qualified.

[0042] Furthermore, the top surface of the base 1 is rotatably connected with a gear ring 7 , which can be raised and lowered in two sections. A gear 701 is provided on the bottom surface of the threaded adjustment column 601 , and the gear ring 7 is meshed with multiple gears 701 at the same time.

[0043] By adopting the above design, when in use, the staff can press the gear ring 7, and adjust a certain threaded adjustment column 601 by rotating the gear 701 alone, or rotate the gear ring 7 to drive all the gears 701 to rotate together, rotate multiple threaded adjustment columns 601, and synchronously adjust the resistance arm lever 401 coefficients of multiple adjustment plates 4.

[0044] Furthermore, a threaded opening 301 is provided on the top surface of the connecting column 3 , a through hole is provided at the center of the placing plate 2 , a threaded column 302 is inserted into the through hole, and the threaded column 302 is threadedly connected in the threaded opening 301 .

[0045] By adopting the above design, when in use, if it is necessary to inspect and replace the adjusting plate 4, the tension spring 5 and other parts, the threaded column 302 can be unscrewed from the threaded mouth 301, the placement plate 2 can be simply and quickly removed from the connecting column 3, and then the placement plate 2 can be turned over to inspect and maintain the adjusting plate 4, the tension spring 5 and other parts. The above design makes the later work of the device more convenient.

[0046] Furthermore, an indicator light 303 is provided on the outer side of the connecting column 3, and a trigger switch 304 is provided on the bottom surface of the placement plate 2. When the trigger switch 304 and the lever 401 are raised to the highest point, the contact point on the bottom surface of the placement plate 2 coincides. The trigger switch 304 is electrically connected to the indicator light 303. There are multiple indicator lights 303 and trigger switches 304, and the number and position correspond.

[0047] By adopting the above design, when in use, if the power of the drone meets the standard, the lever 401 will rise to the top and touch the placement plate 2, thereby triggering the trigger switch 304. When the trigger switch 304 is triggered, the corresponding indicator light 303 will be turned on. At this time, by judging the flashing of the indicator light 303, it can be simply and clearly judged whether the power of the corresponding arm of the drone is qualified.

[0048] Furthermore, an L-shaped block is provided at the end of the elastic band 402, and a notch adapted to the block is provided at the top of the lever 401.

[0049] By adopting the above design, when testing, if the base 1 of the drone is too high, the L-shaped block can be slid out of the notch and replaced with elastic bands 402 of different lengths to adapt to the distance between the drone arm and the placement plate 2, thereby improving the practicality of the device.

[0050] Furthermore, the top of the elastic band 402 is connected to a mounting plate 403, one end of a Velcro 404 is fixedly connected to one side of the top surface of the mounting plate 403, a rod is provided on the other side of the top surface of the mounting plate 403, and the other end of the Velcro 404 is provided with Velcro.

[0051] By adopting the above design, when winding, the other end of the Velcro 404 can be passed through the top of the drone arm, and then passed under the winding rod, and then connected through Velcro, making the connection between the elastic band 402 and the drone arm more convenient, thereby improving the working efficiency of the device.

[0052] Working principle:

[0053] When in use, firstly, according to the model of the UAV, the two ends of the tension spring 5 are pulled out from the pull ring 602 to replace the tension spring 5, and then the height of the threaded adjustment column 601 is adjusted by rotating the gear ring 7 to meet the power requirements of different UAV power tests.

[0054] Then, the L-shaped block is slid out of the notch and replaced with an elastic band 402 of corresponding length to adapt to the distance between the drone support arm and the placement plate 2.

[0055] Then, the other end of the Velcro 404 can be passed through the top of the drone arm, and then passed under the winding rod, and then connected through Velcro to complete the connection between the elastic band 402 and the drone arm.

[0056] At this time, the drone can be started and launched. During the test, if the power of the drone meets the standard, the lever 401 will rise to the top and touch the placement plate 2, thereby triggering the trigger switch 304. When the trigger switch 304 is triggered, the corresponding indicator light 303 will be turned on. At this time, by judging the flashing of the indicator light 303, it can be simply and clearly judged whether the power of the corresponding arm of the drone is qualified.

[0057] During use, if it is necessary to inspect and replace the adjusting plate 4, the tension spring 5 and other parts, the threaded column 302 can be unscrewed from the threaded mouth 301, the placement plate 2 can be simply and quickly removed from the connecting column 3, and then the placement plate 2 can be turned over to inspect and maintain the adjusting plate 4, the tension spring 5 and other parts.
