[0042] In some embodiments, the first test structure 30 comprises a sleeve 31 connected to the rack 10, a rotating shaft 32 rotatably connected to the sleeve 31, and a torque sensor 33 sleeved on the rotating shaft 32, one end of the rotating shaft 32 is connected to the output shaft 210, so that the rotating shaft 32 is driven to rotate by the output shaft 210, and the torque sensor 33 is used to detect the output torque of the output shaft 210. By energizing the measured object 200, the output torque is formed, and then the output torque of the motor is measured by the torque sensor 33.

[0043] It can be understood that the output shaft 210 drives the rotating shaft 32 to rotate, and the torque sensor 33 is sleeved on the rotating shaft 32, and the output torque of the output shaft 210 can be measured by measuring the torque of the rotating shaft 32. The torque sensor 33 converts the physical change of torque into an accurate electrical signal, so that the measurement can be more accurate.

[0045] It can be understood that by setting the sleeve 31, the rotating shaft 32 is rotatably connected in the sleeve 31, and the sleeve 31 is fixedly connected with the rack 10. The sleeve 31 can support the rotating shaft 32, so that the position of the rotating shaft 32 will not deviate when rotating, and the state of the rotating shaft 32 is more stable, thereby further improving the accuracy of measurement.

[0046] In some embodiments, the first test structure 30 further comprises a mounting bracket 37, the mounting bracket 37 is fixedly connected with the bracket, and the torque sensor 33 can be arranged on the mounting bracket 37.

[0048] In some embodiments, the first test structure 30 further comprises a load structure 34 and a coupling 35, the rotating shaft 32 is connected to the load structure 34 through the coupling 35 away from the one end of the output shaft 210. By setting the load structure 34, the load structure 34 can provide stable load conditions to ensure the accuracy and reliability of the test results.

[0049] Specifically, the load structure 34 can be a load motor, which can simulate the load conditions and working conditions of the test piece 200 in actual application, and help test the performance of the motor under different load conditions and working conditions. By controlling the speed and load characteristics of the load motor, the efficiency and stability of the motor can be more accurately evaluated. By controlling the parameters of the load motor, precise control of the test piece 200 can be achieved, avoiding test errors caused by unstable load.

[0050] In some embodiments, the first test structure 30 further comprises a connecting piece 60 connecting the rotating shaft 32 and the output shaft 210, the connecting piece 60 comprising a first connecting part 61 and a second connecting part 62 in transmission cooperation with the first connecting part 61, the first connecting part 61 being provided with a plug-in hole 611 at the end facing the output shaft 210, the plug-in hole 611 being used for plug-in fixing with the output shaft 210, and the second connecting part 62 being fixedly connected with the rotating shaft 32.

[0051] It can be understood that the plug-in hole 611 is arranged along the first direction a towards the transfer structure 20, and the output shaft 210 of the test piece 200 on the transfer structure 20 is opposite to the plug-in hole 611, when the transfer structure 20 drives the test piece 200 to move along the first direction a, the test piece 200 gradually approaches the first test structure 30, and finally the output shaft 210 of the test piece 200 is inserted into the plug-in hole 611, so as to realize the docking of the test piece 200 and the first test structure 30.

[0052] In some embodiments, the plug-in hole 611 comprises a first through hole and a second through hole 6112 in communication with each other, the first through hole and the second through hole 6112 are arranged in sequence along the direction close to the output shaft 210, and the output shaft 210 is provided with a clamping part 211, and the second through hole 6112 is used for clamping and fixing with the clamping part 211.

[0053] It can be understood that the clamping part 211 is arranged at the end of the output shaft 210 away from the first test structure 30, when the output shaft 210 is inserted into the plug-in hole 611, the front end of the output shaft 210 passes through the second through hole 6112 and enters the first through hole 6111, at this time, when the output shaft 210 continues to move, the clamping part 211 will be clamped with the inner wall of the second through hole 6112, so as to fix the output shaft 210.

[0054] Specifically, the second through hole 6112 is a polygonal hole structure, and the clamping portion 211 is also a polygonal column structure matching the shape of the second through hole 6112, so that the second through hole 6112 can be clamped and fixed with the clamping portion 211.

[0055] It should be noted that when the test piece 200 is docked with the first test structure 30, the test piece 200 has not been powered on at this time, and since the load motor is connected to the rotating shaft 32, the load motor can drive the rotating shaft 32 to rotate, thereby driving the first connecting portion 61 to rotate, so that the position of the insertion hole 611 can be finely adjusted in the circumferential direction, thereby enabling the insertion hole 611 to be more smoothly docked with the output shaft 210.

[0056] In some embodiments, the second connecting portion 62 is provided with a connecting hole 621 at an end away from the rotating shaft 32, the hole wall of the connecting hole 621 is provided with a spline groove 6211, the first connecting portion 61 is provided with a connecting shaft 612 inserted into the connecting hole 621 at an end away from the output shaft 210, and the outer circumferential surface of the connecting shaft 612 is provided with a spline 6121 matched with the spline groove 6211. The first connecting portion 61 and the second connecting portion 62 are connected through the spline 6121 structure, thereby connecting the output shaft 210 and the rotating shaft 32, making the connection between the output shaft 210 and the rotating shaft 32 stable, and ensuring the transmission efficiency.

[0057] In some embodiments, the test device further comprises a moving structure 50 slidingly arranged on the rack 10, and the second test structure 40 is arranged on the moving structure 50. The moving structure 50 is used to drive the second test structure 40 to move towards or away from the test piece 200. After the connecting piece 60 clamps the output shaft 210 of the test piece 200, the moving structure 50 starts to drive the second test structure 40 to move towards or away from the test piece 200, so that the second test structure 40 starts to detect the test piece 200.

[0058] Specifically, the second test structure 40 comprises an acceleration sensor 41 and a microphone 42.

Specifically, the third direction c is parallel to the vertical direction, that is, the first moving assembly 51 and the second moving assembly 52 are respectively located at the top and the side of the test piece 200, so that the test piece 200 can be detected from multiple directions, thereby improving the comprehensiveness and accuracy of the test. Specifically, the first moving assembly 51 and the second moving assembly 52 can be a linear motor, an electric sliding table or an electric guide rail.

[0062] In some embodiments, the transfer structure 20 includes a sliding rail 21 extending along the first direction a and a sliding platform 22 slidingly connected to the sliding rail 21, and the sliding platform 22 is used to place the test piece 200.
