[0043] The features and exemplary embodiments of various aspects of this application will be described in detail below. To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain this application and not to limit it. For those skilled in the art, this application can be implemented without some of these specific details. It should be noted that, unless otherwise stated, the technical or scientific terms used in the embodiments of this application should have the ordinary meaning understood by those skilled in the art to which the embodiments of this application pertain. The following description of the embodiments is merely to provide a better understanding of this application by illustrating examples of this application.

[0044] like Figures 1 to 4 As shown in the embodiment of this application, the motor product testing platform includes a transmission shaft component 1, a loading system 2, and a testing system 3.

[0045] The transmission shaft component 1 has a first end and a second end arranged opposite to each other along its axial direction. The first end is used to connect to the output end of the motor product. The output end can be directly the output shaft of the motor, or connected to the end of the transmission structure of the output shaft.

[0046] The output end drives the transmission shaft component 1 to rotate synchronously. During the test, loading the transmission shaft component 1 is equivalent to loading the output end of the motor product, and testing the transmission shaft component 1 is equivalent to testing the motor product.

[0047] The loading system 2 is connected to the second end of the drive shaft component 1. The loading system 2 is configured to apply a rated load and / or a sudden load to the drive shaft component 1 to simulate the load stress of the motor product under different usage environments.

[0048] The detection system 3 is connected between the first end and the second end of the transmission shaft component 1. The detection system 3 is configured to detect the torque on the transmission shaft component 1 in real time, so as to evaluate the performance of the motor product based on the detection data, which helps to verify the design performance of the motor product and ensure the reliability and stability of the motor product in actual application.

[0049] like Figures 1 to 4 As shown in the embodiment of this application, the motor product testing platform includes a loading system 2 comprising a rated loading device 21 and a sudden loading device 22.

[0050] The rated loading device 21 is connected to the second end of the drive shaft component 1, and applies a continuous and stable rated load to the drive shaft component 1. The rated load mainly simulates the load stress of the motor product when it is working in a continuous and stable environment.

[0051] The sudden load device 22 is connected to the drive shaft component 1 via an opening and closing device 23. The opening and closing device 23 has an open state and a closed state. In the open state, the sudden load device 22 applies a sudden load to the drive shaft component 1; in the closed state, the sudden load device 22 stops applying the sudden load to the drive shaft component 1. It can be understood that the load intermittently applied to the drive shaft component 1 by switching between the open and closed states of the opening and closing device 23 serves as the sudden load. The sudden load mainly simulates the load stress on the motor product when the operating environment of the motor product undergoes a sudden change.

[0052] like Figures 1 to 4 As shown in the embodiment of this application, the motor product testing platform includes an opening and closing device 23 comprising a first component 231 and a second component 232 that can be connected or separated from each other.

[0053] The first component 231 is fixedly sleeved on the transmission shaft component 1, and the first component 231 rotates synchronously with the transmission shaft component 1.

[0054] The second component 232 is movably sleeved on the transmission shaft component 1. The second component 232 is connected to the sudden loading device 22. The second component 232 does not rotate synchronously with the transmission shaft component 1 when it is separated from the first component 231.

[0055] In the open state, the first component 231 is connected to the second component 232, and both the second component 232 and the first component 231 rotate synchronously with the transmission component. At this time, the sudden loading device 22 applies a load as a sudden load to the transmission shaft component 1 through the second component 232 and the first component 231. In the closed state, the first component 231 is separated from the second component 232, and the transmission shaft component 1 can rotate relative to the second component 232. That is, the second component 232 no longer rotates synchronously with the transmission shaft component 1. At this time, the load applied by the sudden loading device 22 cannot be transmitted to the transmission shaft component 1 through the second component 232, and the transmission shaft component 1 is no longer subjected to a sudden load.

[0056] By controlling the connection and separation of the first component 231 and the second component 232, different modes of sudden loads can be applied to the transmission shaft component 1 as needed.

[0057] like Figures 1 to 4 As shown in the embodiment of this application, the motor product testing platform includes an opening and closing device 23 that is an electromagnetic clutch. The first component 231 and the second component 232 are connected or separated by electromagnetic force, which can effectively realize the electrical control of the opening and closing device 23 and improve the control flexibility and convenience.

[0058] like Figures 1 to 4 As shown in the embodiment of this application, the motor product testing platform includes a loading system 2 that further includes a transmission device 24. The transmission device 24 is connected between the sudden load device 22 and the second component 232 to realize the transmission connection between the sudden load device and the second component 232, so that the sudden load is smoothly applied to the transmission shaft structure to simulate the working condition of the motor product when subjected to a sudden load.

[0059] like Figures 1 to 4 As shown in the embodiment of this application, the motor product testing platform includes a transmission device 24 comprising a first transmission wheel 241, a second transmission wheel 242, and a transmission chain 243. The transmission chain 243 is tensioned and wound around the first transmission wheel 241 and the second transmission wheel 242. Both the first transmission wheel 241 and the second transmission wheel 242 are transmission gears that mesh with the transmission chain 243, effectively ensuring transmission efficiency and preventing slippage of the transmission chain 243.

[0060] The first transmission wheel 241 is sleeved on the transmission shaft component 1 and fixedly connected to the second component 232. The second transmission wheel 242 is fixedly connected to the sudden load device 22 to ensure that the sudden load applied by the sudden load device 22 can be reliably transmitted to the second transmission wheel 242 and then reliably transmitted to the second transmission wheel 242 through the transmission chain 243. Then, it is reliably transmitted to the second component 232 through the second transmission wheel 242. When the second component 232 is connected to the first component 231, a sudden load can be applied to the transmission shaft structure.

[0061] like Figures 1 to 4 As shown in the embodiment of this application, the motor product testing platform includes a detection system 3 comprising a torque-speed sensor 31, through which the transmission shaft component 1 is rotatably mounted. By setting the torque-speed sensor 31, not only can the torque of the transmission shaft component 1 and the motor product be tested, but the rotational speed of the output end of the transmission shaft component 1 and the motor product can also be detected in real time, allowing for a more comprehensive test of the motor product, obtaining more test results, and improving the comprehensiveness of the performance evaluation of the motor product.

[0062] like Figures 1 to 4 As shown in the embodiment of this application, the motor product testing platform includes a detection system 3 that further comprises an angle disk 32 and a pointer 33. The angle disk 32 and the pointer 33 work together to detect the rotation angle of the rotating shaft component and the output end of the motor product.

[0063] Angle disc 32 is fitted onto transmission shaft component 1 and is fixedly connected to torque and speed sensor 31. Angle disc 32 does not rotate with transmission shaft component 1. Angle disc 32 is provided with angle scale lines.

[0064] The pointer 33 is connected to the transmission shaft component 1 and rotates synchronously with it. The pointer 33 is positioned opposite the angle disk 32 along the axial direction of the transmission shaft component 1. By projecting the pointer 33 along the axial direction of the transmission shaft component 1 onto the angle disk 32, the rotation angle of the transmission shaft component 1 and the output end of the motor product can be read. This allows for testing of the motor product, obtaining more test results, and further improving the comprehensiveness of the performance evaluation of the motor product.

[0065] like Figures 1 to 4 As shown in the embodiment of this application, the motor product testing platform further includes a control system 4, which is electrically connected to the loading system 2 and controls the loading mode of the loading system 2.

[0066] The control system 4 includes a first control device 41 and a second control device 42; the first control device 41 is electrically connected to the rated loading device 21 and the sudden loading device 22 respectively, and the first control device 41 is used to adjust the loading torque of the rated loading device 21 and the sudden loading device 22; the second control device 42 is electrically connected to the opening and closing device 23, and the second control device 42 is used to control the application and cessation of the sudden load.

[0067] like Figures 1 to 4 As shown in the embodiment of this application, the motor product testing platform includes a transmission shaft component 1 comprising multiple shaft segments 11 along its axial direction. By setting multiple shaft segments 11, the stress on the transmission shaft component 1 can be optimized and the deformation of the transmission shaft component 1 can be reduced compared to a complete long shaft.

[0068] Each pair of adjacent shafts 11 is connected by a coupling 12, which connects the shafts 11 to form a complete transmission shaft structure. The detection system 3 and the loading system 2 are respectively connected to at least one shaft 11, and the shafts 11 connect the detection system 3 to the transmission shaft component 1 and the loading system 2 to the transmission shaft component 1.

[0069] like Figures 1 to 4 As shown in the embodiment of this application, the motor product testing platform includes a base plate 5, which is laid horizontally. The upper surface of the base plate 5 forms a mounting surface for mounting the loading system 2, the detection system 3, the transmission shaft component 1, and the motor product.

[0070] The base plate 5 is provided with multiple supports 51, and the transmission shaft component 1 passes through each support 51 in sequence. By setting the supports 51, the transmission shaft component 1 can be effectively supported, reducing the downward bending of the transmission shaft component 1 in the middle position due to gravity.

[0071] The drive shaft component 1 is rotatably connected to the bracket 51 via the bearing 52, which reduces the friction between the drive shaft component 1 and the bracket 51 when the drive shaft component 1 rotates relative to the bracket 51, thereby slowing down the wear of the drive shaft component 1 and the bracket 51.

[0072] Optionally, the bracket 51 closest to the first end of the drive shaft component 1 can be used as the mounting base for the motor product. Specifically, if the projection of the output end of the motor product along the axial direction of the drive shaft component 1 is exactly concentric with the projection of the drive shaft component 1 along its axial direction, the output end of the motor product can be directly connected to the drive shaft component 1. If the projection of the output end of the motor product along the axial direction of the drive shaft component 1 is misaligned with the projection of the drive shaft component 1 along its axial direction, the motor product can be fixed on the bracket 51 by the limiting member 53 so that the projection of the output end of the motor product along the axial direction of the drive shaft component 1 is exactly concentric with the projection of the drive shaft component 1 along its axial direction. In this case, connecting the drive shaft component 1 and the output end of the motor product can effectively realize the transfer of load between the two and reduce stress concentration.

[0073] Both the detection system 3 and the loading system 2 can be detachably mounted on the base plate 5. Specifically, the base plate 5 is provided with a base 34 corresponding to the detection system 3 and the loading system 2, and the torque speed sensor 31, the rated loading device 21 and the sudden loading device 22 are respectively mounted on the corresponding base 34.

[0074] Optionally, the substrate 5 is provided with multiple feet 54 at its bottom to provide support for the substrate 5. When applied to uneven ground, the height of the substrate 5 can be adjusted by adjusting the feet 54 to keep the substrate 5 level and ensure that the components installed on the substrate 5 are subjected to uniform force.

[0075] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
