[0044] In one embodiment, Figure 1 As shown, a torque detection device is provided, including a base 120, a driving device 140, a measuring device 110, and a controller 130. The torque detection device is used to detect the torque of the device under test 100. The controller 130 is in communication with the measuring device 110, and the controller 130 is in communication with the driving device 140. The controller 130 outputs a driving instruction to the driving device 140 to control the operation of the driving device 140. The controller 130 outputs a detection instruction to the measuring device 110 to control the operation of the measuring device 110 to obtain the torque of the device under test 100.

[0045] The device under test 100 includes, but is not limited to, various types of motors under test, such as DC motors, electromagnetic motors, and stepper motors. A motor refers to an electromagnetic device that converts or transmits electrical energy according to the law of electromagnetic induction. Its main function is to generate driving torque, also known as torque. The motor includes a stator and a rotor. The main function of the stator is to generate a main magnetic field and serve as a mechanical support. When the stator is fixedly connected to the housing, it can also be called a housing stator. The main function of the rotor is to generate induced electromotive force and electromagnetic torque. The rotor includes rotating parts such as a rotor core and a rotating shaft. The rotating shaft can be used to support rotating parts, transmit torque, and determine the relative position between the rotating parts and the stator. The rotating shaft can also be called an output shaft.

[0046] Specifically, the device under test 100 includes a fixed member and a rotating member that rotates relative to the fixed member. The fixed member includes a stator that is fixedly connected to the housing, and the rotating member includes a rotor that is fixedly connected to the rotating shaft. When the fixed and rotating members rotate relative to each other through a preset angle, different torques are generated when the device under test 100 is started and transmitted through its output shaft. The preset angle of relative rotation between the rotating and fixed members can be achieved by either the rotating member being stationary while the fixed member rotates through the preset angle, or the fixed member being stationary while the rotating member rotates through the preset angle.

[0047] The measuring device 110 includes, but is not limited to, a torque sensor, a torque meter, and a torque meter, and can specifically be a torque meter. The measuring device 110 is mounted on a base 120 and connected to a rotating member in the device under test 100, specifically, the output shaft of the device under test 100. During the startup of the device under test 100, the measuring device 110 is used to obtain the torque generated by the relative rotation of the rotating member and the fixed member at a predetermined angle.

[0048] The driving device 140 is a device that controls and drives the device under test 100 to rotate so that the rotating member and the fixed member of the device under test 100 rotate relative to each other by a predetermined angle. The driving device 140 includes, but is not limited to, various types of driving motors, such as a DC motor, an electromagnetic motor, and a stepper motor.

[0049] The controller 130 may be an electronic device including various control chips, control circuits, and smart terminals. Specifically, the controller 130 is configured to determine the rotation angles of the device under test 100 for a full rotation based on a preset detection step size; sequentially select a rotation angle from each rotation angle as a target rotation angle; output a drive instruction to the drive device 140, the drive instruction being used to instruct the drive device 140 to drive a fixed member in the device under test 100 to rotate to the target rotation angle; output a start instruction and a detection instruction to the measuring device 110, the start instruction being used to control the start of the device under test 100, and the detection instruction being used to instruct the measuring device 110 to detect the torque of the device under test 100 at the target rotation angle during the start-up process of the device under test 100.

[0050] In one embodiment, Figure 2 As shown, a torque detection device is provided, including a driving device 140, a base 120, a measuring device 110 and a controller 130, which is not shown.

[0051] The drive device 140 and the measuring device 110 are in communication with the controller 130. The controller 130 outputs a drive instruction to the drive device 140 to control the operation of the drive device 140, thereby driving the device under test 100 to rotate by a preset angle, so that the rotating member and the fixed member of the device under test 100 rotate relative to each other by the preset angle. The controller 130 outputs a start instruction and a detection instruction to the measuring device 110 to control the startup of the device under test 100 and to control the measuring device 110 to detect the torque of the device under test 100 during the startup process of the device under test 100. The drive device 140 includes, but is not limited to, various types of drive motors, and specifically can be a stepper motor.

[0052] Specifically, the driving device 140 can be configured to drive the rotation of a fixed component in the device under test 100. Specifically, the driving device 140 is mounted on the base 120 and is in transmission connection with the fixed component in the device under test 100, thereby controlling the rotation of the fixed component. The output shaft 1401 of the driving device 140 is in transmission connection with the fixed component in the device under test 100. Thus, when the driving device 140 is controlled to rotate by a preset angle, the output shaft 1401 of the driving device 140 causes the fixed component in the device under test 100 to rotate by the preset angle, while the rotating component in the device under test 100 remains stationary, thereby causing the rotating component and the fixed component of the device under test 100 to rotate relative to each other by the preset angle.

[0053] The measuring device 110 is mounted on a base 120 and connected to a rotating member in the device under test 100. After the fixed member of the device under test 100 rotates by a preset angle, the rotating member transmits the torque of the device under test 100 during the controlled startup of the device under test 100, so that the measuring device 110 can obtain the torque generated by the relative rotation of the rotating member and the fixed member in the device under test 100 by the preset angle.

[0054] The base 120 includes a base 1201 and a bracket 1202. The base 1201 is provided with a receiving cavity. The driving device 140 is received in the receiving cavity, and its output shaft 1401 is kept at least partially exposed from the base 1201, so that the driving device 140 remains stable and motionless during the controlled operation, and the output shaft 1401 of the driving device 140 is connected to the fixed part of the device under test 100 in a transmission manner, so that the driving device 140 can drive the fixed part of the device under test 100 to rotate in a controlled manner.

[0055] Specifically, bracket 1202 includes a first arm 1203 and a second arm 1204 arranged to intersect each other. One end of first arm 1203 is connected to base 1201, and one end of second arm 1204 is connected to the other end of first arm 1203, thereby securing bracket 1202 to base 1201. Measuring device 110 is coupled to the other end of second arm 1204 and is connected to a rotating member in device under test 100, specifically, to output shaft 1001 of device under test 100, so that measuring device 110 detects the torque transmitted by output shaft 1001 of device under test 100.

[0056] The first arm 1203 extends vertically on the base 120, and the second arm 1204 extends horizontally at an end of the first arm 1203 away from the base 120. Specifically, the first arm 1203 and the first arm 1204 are perpendicularly arranged. When the measuring device 110 is coupled to the second arm 1204, the measuring device 110 is perpendicular to the output shaft 1001 of the device under test 100, and the measuring device 110 is arranged horizontally, thereby improving the accuracy of the measuring device 110 in detecting the torque during the startup of the device under test 100.

[0057] Among them, the output shaft 1001 of the device under test 100 and the output shaft 1401 of the driving device 140 are located on the same axis, so that when the driving device 140 is controlled to rotate by a preset angle, it drives the fixed part in the device under test 100 to rotate by a preset angle, thereby improving the rotational accuracy of the fixed part in the device under test 100, thereby improving the accuracy of the measuring device 110 in detecting the torque during the startup process of the motor under test 100.

[0058] In one embodiment, Figure 3 As shown, a torque detection device is provided, including a clamp 150, a driving device 140, a base 120, a measuring device 110 and a controller 130, which is not shown.

[0059] Among them, the driving device 140 and the measuring device 110 are communicatively connected to the controller 130, the controller 130 outputs a driving instruction to the driving device 140, controls the driving device 140 to work, drives the rotating fixture 150 to a preset angle, so that the fixture 150 drives the rotating part and the fixed part of the device under test 100 to rotate relative to each other by a preset angle, the controller 130 outputs a start instruction and outputs a detection instruction to the measuring device 110, controls the start of the device under test 100, and controls the measuring device 110 to detect the torque of the device under test 100 during the start-up process of the device under test 100.

[0060] The driving device 140 can be configured to rotate the fixture 150 so that the fixture 150 drives the fixed component of the device under test 100 to rotate. Specifically, the driving device 140 is housed in a housing cavity defined in the base 1201, with its output shaft 1401 at least partially exposed to the base 1201. The fixture 150 is supported on the base 120, specifically on the base 1201. The device under test 100 is housed within the fixture 150. The fixture 150 is in transmission connection with the output shaft 1401 of the driving device 140. When the driving device 140 is controlled to rotate by a preset angle, the output shaft 1401 of the driving device 140 drives the fixture 150 to rotate by the preset angle, thereby causing the fixture 150 to drive the fixed component of the device under test 100 to rotate. The fixture 150 can be a fixed turntable capable of rotating and locking the device under test 100. Furthermore, the shape and material of the fixture 150 are not limited; as long as the aforementioned functions can be achieved, they are within the scope of protection of this application.

[0061] The arrangement and position of the base 120 and the measuring device 110 are similar to Figure 2 The torque detection equipment shown is the same and will not be described again here.

[0062] In one embodiment, Figure 4 As shown, a torque detection device is provided, including a driving device 140, a base 120, a measuring device 110 and a controller 130, which is not shown.

[0063] Among them, the driving device 140 and the measuring device 110 are communicatively connected to the controller 130, the controller 130 outputs a driving instruction to the driving device 140, controls the driving device 140 to work, drives the rotating measuring device 110 to rotate by a preset angle, so that the measuring device 110 drives the rotating part and the fixed part of the device under test 100 to rotate relative to each other by a preset angle, the controller 130 outputs a start instruction and outputs a detection instruction to the measuring device 110, controls the start of the device under test 100, and controls the measuring device 110 to detect the torque of the device under test 100 during the start-up process of the device under test 100.

[0064] Specifically, the driving device 140 can be configured to drive a rotating member in the device under test 100 to rotate. The driving device 140 can drive the rotating member in the device under test 100 to rotate via the measuring device 110. The driving device 140 is housed within a housing cavity defined in the base 1201, with its output shaft 1401 at least partially exposed from the base 1201. The measuring device 110 is in transmission connection with the output shaft 1401 of the driving device 140. The measuring device 110 is in transmission connection with the rotating member in the device under test 100, and is controlled to drive the rotating member to rotate. Specifically, the measuring device 110 is in transmission connection with the output shaft 1401 of the driving device 140. The driving device 140 is controlled to drive the measuring device 110 to rotate by a preset angle. The measuring device 110 is connected to the rotating member in the device under test 100, and when the measuring device 110 rotates, the rotating member in the device under test 100 is driven to rotate by the preset angle, thereby causing the rotating member and the fixed member of the device under test 100 to rotate relative to each other by the preset angle. During the startup of the device under test 100 , the measuring device 110 can obtain the torque of the device under test 100 .

[0065] The base 120 includes a base 1201 and a bracket 1202. The bracket 1202 includes a first arm 1203 and a second arm 1204 that are intersecting. One end of the second arm 1204 is connected to the other end of the first arm 1203. Figure 2 Compared with the torque detection device shown in FIG, the connection point between the first arm 1203 and the second arm 1204 is closer to the base 1201. The way and position of the base 1201 are set, and Figure 2 The torque detection equipment shown is the same and will not be described again here.

[0066] The above-mentioned torque detection device includes a base 120, a driving device 140, a measuring device 110 and a controller 130. The measuring device 110 is installed on the base 120 and is connected to the rotating part in the device under test 100, and is used to obtain the torque generated by the relative rotation of the rotating part and the fixed part at a preset angle. The controller 130 is communicated with the driving device 140 and the measuring device 110, outputs a driving instruction to the driving device 140, and outputs a detection instruction to the measuring device 110. It can accurately control the relative rotation of the fixed part and the rotating part in the device under test 100 at a preset angle, and can realize automatic detection of the torque of the device under test 100 during the startup process, thereby improving the torque detection efficiency of the device under test 100 during the startup process.

[0067] In one embodiment, Figure 5 As shown, a torque detection method is provided, which is applied to Figure 1 The controller 130 in FIG. 1 is used as an example to illustrate the invention, including:

[0068] Step S502 : determining each rotation angle of the device under test during a full rotation based on a preset detection step size.

[0069] In one embodiment, the device under test is a motor under test, and a full rotation of the device under test refers to a relative rotation of one circle between a fixed part and a rotating part in the device under test, i.e., a relative rotation of 360°, rather than a 360° rotation of the device under test as a whole. The fixed part of the device under test includes a stator, and the rotating part includes a rotor. During the torque detection process of the device under test, the fixed part and the rotating part in the device under test are controlled to rotate relative to each other from an initial state, i.e., 0°, to 360°. Specifically, the fixed part in the device under test may be stationary while the rotating part rotates in a controlled manner, or the rotating part in the device under test may be stationary while the fixed part rotates in a controlled manner.

[0070] In one embodiment, the preset detection step size refers to the minimum rotation angle between a previous detection and a subsequent detection when detecting the torque of the device under test. The preset detection step size can be set based on the detection requirements and is greater than or equal to the control accuracy of the driving device. For example, if the control accuracy of the driving device is 1°, the preset detection step size must be set to be greater than or equal to 1°.

[0071] In one embodiment, the controller determines the various rotation angles of the device under test for a full rotation based on a preset detection step. Specifically, the number of rotations of the device under test for a full rotation is determined based on the preset detection step. For example, if the preset detection step is set to 36°, the number of rotations of the device under test for a full rotation of 360° is 10 times, which is equivalent to 10 detection times. Furthermore, based on the number of rotations and the preset detection step, the various rotation angles of the device under test for a full rotation are calculated. The number of rotations is subtracted from the preset value, and the difference is multiplied by the preset detection step to calculate the rotation angle corresponding to the number of rotations, thereby obtaining the various rotation angles of the device under test for a full rotation, and the preset value is set to 1. For example, the preset detection step is set to 36°, and the number of rotations is 10 times. During the first detection, the rotation angle of the device under test is 0°, that is, the detection is in the initial state. During the second detection, the rotation angle of the device under test is 36°. During the third detection, the rotation angle of the device under test is 72°. And so on. During the tenth detection, the rotation angle of the device under test is 324°.

[0072] Step S504: Select one rotation angle from each rotation angle in turn as the target rotation angle.

[0073] In one embodiment, the controller sequentially selects a rotation angle from each rotation angle as the target rotation angle. Specifically, based on the number of rotations, the controller selects a rotation angle corresponding to the number of rotations from each rotation angle as the target rotation angle. After each control to detect the torque of the device under test, the controller records the number of rotations and the corresponding target rotation angle so that the controller can select a rotation angle as the target rotation angle the next time.

[0074] Step S506 : outputting a driving instruction to the driving device, where the driving instruction is used to instruct the driving device to drive the fixed component in the device under test to rotate to a target rotation angle.

[0075] In one embodiment, after determining the target rotation angle, the controller outputs a drive instruction to a drive device, the drive instruction including the target rotation angle, and the drive instruction instructs the drive device to rotate a fixed member in the device under test by the target rotation angle. The drive device includes a stepper motor.

[0076] In one embodiment, the driving device may directly drive the fixed part in the device under test to rotate, or may drive the fixed part in the device under test to rotate through an intermediary. When the driving device directly drives the fixed part in the device under test to rotate, the output shaft of the driving device is directly connected to the fixed part in the device under test, so that when the driving device is controlled to rotate, the output shaft of the driving device directly drives the fixed part in the device under test to rotate. When the driving device drives the fixed part in the device under test to rotate through an intermediary, the intermediary may be a fixture. The output shaft of the driving device is connected to the fixture, and the device under test is placed in the fixture, which is equivalent to the fixture clamping the fixed part of the device under test, so that the driving device drives the fixture to rotate, and the fixture drives the fixed part in the device under test to rotate, so as to achieve the purpose of rotating the fixed part in the device under test.

[0077] In one embodiment, the fixture can be a fixed turntable capable of rotating and locking the device under test. After the driving device rotates the fixed component of the device under test to a target rotation angle according to the driving instruction, the device under test is locked by the fixture to prevent interference with the startup of the device under test. Furthermore, the shape and material of the fixed turntable are not limited.

[0078] Step S508 , outputting a start instruction and a detection instruction to the measuring device, wherein the start instruction is used to control the start of the device under test, and the detection instruction is used to instruct the measuring device to detect the torque of the device under test at the target rotation angle during the start-up process of the device under test.

[0079] In one embodiment, the measuring device is a device for measuring the torque of the device under test, and can specifically be a torque measuring instrument. A controller is communicatively connected to the measuring device, and the measuring device is connected to a rotating part in the device under test, that is, the measuring device is connected to the output shaft of the device under test, so that when the measuring device is started, the torque can be detected through the output shaft of the measuring device. Specifically, the controller outputs a start-up instruction and outputs a detection instruction to the measuring device, and the start-up instruction is used to control the start-up of the device under test, that is, to turn on the power switch of the device under test and energize the device under test. The detection instruction is used to instruct the measuring device to detect the torque of the device under test at a target rotation angle during the startup of the device under test.

[0080] In one embodiment, when a fixed member in the device under test is stationary and a rotating member is controlled to rotate, the driving device can also drive the rotating member in the device under test to rotate. Specifically, the driving device can drive the rotating member in the device under test to rotate via a measuring device. The output shaft of the driving device is in transmission connection with the measuring device, which is in transmission connection with the rotating member in the device under test. When the driving device drives the measuring device to rotate by a target rotation angle, the measuring device is controlled to drive the rotating member in the device under test to rotate by a target preset angle.

[0081] In one embodiment, since the measuring device measures the torque generated by the relative rotation of the rotating part and the fixed part in the device under test by a preset angle, the controller can also be directly connected to the device under test for communication. When the fixed part in the device under test is fixed, the controller directly outputs a drive instruction to the device under test, so that the rotating part in the device under test rotates the target rotation angle, and then outputs a start instruction and a detection instruction to the measuring device. The start instruction is used to control the start of the device under test, and the detection instruction is used to instruct the measuring device to detect the torque of the device under test at the target rotation angle during the startup of the device under test.

[0082] In the above torque detection method, the various rotation angles of the device under test for a full rotation are determined based on a preset detection step size; one rotation angle is selected from each rotation angle in turn as the target rotation angle; a drive instruction is output to a drive device, the drive instruction is used to instruct the drive device to drive a fixed part in the device under test to rotate to the target rotation angle; a start instruction is output and a detection instruction is output to a measuring device, the start instruction is used to control the start of the device under test, and the detection instruction is used to instruct the measuring device to detect the torque of the device under test at the target rotation angle during the start-up process of the device under test. By adopting the method of the above embodiment, the control instruction output by the controller instructs the drive device to drive the fixed part in the device under test to rotate to the preset angle, and controls the measuring device to measure the torque during the start-up process of the device under test, which can improve the control accuracy, save measurement time, and improve the detection efficiency of the torque during the start-up process of the device under test.
