[0002] With economic development and the continued research and development of electronic technology, propeller drones, such as DJI drones, have become widely used. The drone industry has evolved beyond its purely military focus and is rapidly expanding into civilian, police, and household applications. The drone's motor and propeller form its power system. The motor drives the propeller, providing the power for the drone's ascent. Its performance directly determines the drone's flight safety and efficiency. Therefore, it's essential to perform performance tests on motors and propellers, including lift, speed, power, efficiency, and torque. This data is then analyzed to continuously improve the motor's performance.

[0003] Currently, when testing the lifting force of drone motors, force measuring instruments are often used to test the force of running drone motors with blades. The test data of the lifting force of drone motors is related to the size of the blades. In order to obtain test data for drone motors with multiple blade sizes, it is necessary to manually disassemble and assemble the blades frequently at the output end of the motor, which increases the detection burden on the performance test of drone motors.

DETAILED DESCRIPTION

[0020] The following describes the implementation of the present invention through specific embodiments. Those skilled in the art can readily understand the other advantages and benefits of the present invention from the contents disclosed in this specification. Obviously, the embodiments described are only a portion of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0021] See also Figures 1-4 The utility model provides a detection device for testing a drone motor, including a base 1, a bracket assembly 2 is fixedly connected to the base 1, and the bracket assembly 2 is made of a metal structure to form a frame to provide structural support. A pair of sliding connectors 3 are provided on the bracket assembly 2, one of the sliding connectors 3 is provided with a pull plate 4, one end of the pull plate 4 is detachably connected to a drone motor 5, and the output end of the drone motor 5 is provided with a gear 51, which can be connected to the output end of the drone motor 5 by a bolt, and a tension sensor is movably connected to the pull plate 4. Device 6, the model of the tension sensor 6 in this application is TD-CLF-L3. Since it is an existing disclosed technical structure, it will not be described in detail here. The tension sensor 6 is connected to the bracket assembly 2, and a pair of sliding connectors 3 are provided with a fixed frame 7, and a rotating frame body 8 is provided on the fixed frame 7. A plurality of blades 9 are provided on the rotating frame body 8, and the blades 9 are connected to the rotating frame body 8 through a rotating shaft. A gear 2 10 meshing with a gear 1 51 is provided at one end of the rotating shaft on the blade 9. The plurality of gears 2 10 are distributed in a ring structure, and the gear 1 51 is arranged on the path of the ring structure.

[0022] It is worth noting that the area on the base 1 in this application can be set with components such as a power supply for the drone motor 5, a driving controller, and a display panel for identifying and displaying data from the tension sensor 6.

[0023] The sliding connection 3 includes a slide rail 31, which is fixedly connected to the bracket assembly 2. A slide plate 32 is slidably connected to the slide rail 31, and the pull plate 4 is fixedly connected to the slide plate 32. The sliding cooperation between the slide rail 31 and the slide plate 32 can provide a linear guide for the position of the UAV motor 5 and the blade 9. When the UAV motor 5 drives the blade 9 and provides a pulling force, the pulling force can cooperate with the detection equipment to perform force detection.

[0024] A tension groove 11 is provided on the pull plate 4, and the tension sensor 6 is arranged in the tension groove 11. The length of the above-mentioned tension groove 11 is greater than the tension sensor 6. A support plate 12 is fixedly connected to the bracket assembly 2, and the tension sensor 6 is fixedly connected to the support plate 12. The detection part of the tension sensor 6 is set in the tension groove 11. When the drone motor 5 drives the blades 9 and provides a tension, the tension can be contacted by the pull plate 4 and pulled in the detection part of the tension sensor 6. In this way, the effect of the drone motor 5 moving due to the tension can be intuitively found.

[0025] The fixed frame 7 is fixedly connected to a pair of slides 32, and the rotating frame body 8 includes a rotating device 81. The rotating device 81 can adopt a rotating motor, and the rotating motor is a self-locking motor. When the rotating device 81 is in use, a dedicated drive controller is also required to be provided on the base 1, so that the position of the snowflake assembly frame 82 can be stabilized when gear 1 51 and gear 2 10 cooperate independently. The rotating device 81 is fixedly connected to the inner side of the fixed frame 7, and the output end of the rotating device 81 passes through the fixed frame 7 and is connected to the snowflake assembly frame 82. The snowflake assembly frame 82 is composed of a plurality of support plates distributed in a ring and connected together, and the blades 9 are rotatably connected to the support plates through a rotating shaft. In this application, the snowflake assembly frame 82 is composed of a plurality of support plates distributed in a ring and connected together to form the shape of a snowflake, which can meet the requirements of installing multiple blades 9 with a fulcrum.

[0026] The sizes of the multiple blades 9 are different from each other, and the two adjacent blades 9 are not in the same straight line. The setting of the blades 9 in different sizes can meet the testing requirements of various pulling data of the drone motor 5, because the size of the blade 9 can determine the magnitude of the tensile force. The advantage of setting the two adjacent blades 9 not in the same straight line is that when one of the blades 9 is running, the problem of hitting the blade can be effectively avoided.

[0027] An air slot 13 is provided on the support plate of the snowflake assembly frame 82. Since the blades 9 are arranged on one side of the support plate, the position of the air slot 13 can reduce the wind resistance of the blades 9 rotation, so as to maximize the stretching effect of the drone motor 5 in conjunction with the blades 9.

[0028] When the present invention is in use, the angle of the snowflake assembly frame 82 is adjusted by the rotating device 81, so that the support plate end with the blade 9 is moved to the corresponding output end position of the drone motor 5. At this time, the blade 9 and gear 2 10 on the corresponding support plate can be shifted to one side of the drone motor 5. Because gear 1 51 is set on the annular path of multiple gears 2 10, gear 1 51 can be quickly engaged with gear 2 10. By controlling the output of the drone motor 5, gear 1 51 can drive the blade 9 to rotate through gear 2 10, and the blade 9 can drive the slide plate 32 to move on the slide rail 31 by acting on the air. The movement of the slide plate 32 can make the pull plate 4 act on the tension sensor 6, so that the tension sensor 6 can obtain the pulling force brought by the blade 9.
