Abstract
Description
Technical Field
[0001] This utility model relates to the field of testing tooling, and more specifically, to a motor performance testing device. Background Technology
[0002] The electric motor that drives the wheels of a new energy vehicle is the core power component of the vehicle. Its performance directly affects the vehicle's power output, driving range, and safety. Therefore, it needs to undergo various performance tests (such as waterproofing tests and load capacity tests) before leaving the factory to meet the standards for safe use.
[0003] Currently, automotive motor performance testing often employs separate fixtures to test various indicators. For example, waterproof IP rating is tested using a waterproof test chamber, and driving force and torque are tested using a dynamometer system. This decentralized testing approach has several drawbacks: First, the dispersed testing equipment occupies a significant amount of space, and the motor needs to be frequently switched between different devices, resulting in low testing efficiency. Second, repeated disassembly and reassembly of the motor can easily cause wear and tear and increase testing costs. Third, the results of each independent test lack correlation, making it difficult to comprehensively evaluate the motor's true performance under various coupled operating conditions.

[0038] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.
[0039] Please refer to Figure 1 This utility model provides a motor performance testing device, including: a base 1, a gantry frame 2, a spray assembly 3, a load testing assembly 4, and an adjustment assembly 5. The gantry frame 2 is connected to the base 1, and the motor 8 to be tested is placed below the gantry frame 2. The spray assembly 3 is disposed on the gantry frame 2, and the spray assembly 3 is located above and / or to the side of the motor 8 to be tested. The spray assembly 3 is used to spray water on the motor 8 to test its waterproof rating. The load testing assembly 4 includes a fixed support ring 40 and multiple rotating disks 41. The multiple rotating disks 41 are rotatably mounted on the fixed support ring 40, and the output shaft of the motor 8 to be tested can be connected to at least one of the multiple rotating disks 41. The adjustment assembly 5 includes a movable block 50, a lead screw 51, and a drive component 52. The drive component 52 is connected to the lead screw 51, and the movable block 50 is connected to the fixed support ring 40. The movable block 50 is also sleeved on the lead screw 51 and can move along the lead screw 51. When it is necessary to test the load capacity of the motor under test 8, the drive component 52 is activated, the lead screw 51 rotates and drives the movable block 50 to move. The movement of the movable block 50 drives the fixed support ring 40 and multiple rotating disks 41 to move, so that different numbers of rotating disks 41 are connected to the output shaft of the motor under test 8 to test the load performance of the motor under test 8. Of course, waterproof testing can also be performed at the same time as testing the load performance of the motor under test 8, so that the test results are closer to the performance under real working conditions.
[0040] The testing device of this utility model combines motor waterproof performance testing and load performance testing, which can realize two performance tests on the same testing device. The integration of the testing system reduces the space occupation and eliminates the need for frequent changes of testing sites and equipment. It has high testing efficiency, reduced testing costs, and reduced wear during motor testing. Moreover, different performance tests can be coupled with each other, and the test results are closer to the performance under real working conditions.
[0041] Specifically, the gantry 2 is U-shaped, with both ends connected to the base 1 and fixed to the base 1 by welding, bonding, or other methods. Alternatively, the gantry 2 and base 1 can be detachably connected. A triangular plate is also provided at the junction of the gantry 2 and base 1, with its two right-angled sides connecting to the sidewall of the gantry 2 and the base 1 respectively, to strengthen the connection and ensure its firmness and stability. The motor under test 8 is positioned below the gantry 2, and the spray assembly 3 is positioned on the gantry 2 above or to the side of the motor under test 8 for spray testing. The load testing assembly 4 is positioned on the base 1 and is movable via the adjustment assembly 5 to connect or disconnect from the motor under test 8 for load testing.
[0042] refer to Figure 2 and combined Figure 1 The inner side of the gantry 2 is provided with a fixing structure 6, which is used to fix the motor under test 8. The fixing structure 6 provides stable support and positioning for the motor under test 8, so that the motor under test 8 will not shake or vibrate during the test, thereby improving the safety of the test and the accuracy of the test data, and preventing the motor under test 8 from having safety risks during the test.
[0043] The types and forms of the fixing structure 6 can include a variety of things, and there is no limitation on them. This embodiment only lists one as an example for illustration. It should be understood that this example should not be used to limit the form and type of the fixing structure 6.
[0044] In this embodiment, the fixing structure 6 includes a support block 60 and a fixing ring 61. The fixing ring 61 is detachably connected to the support block 60 and is used to fix the motor under test 8. Two support blocks 60 are located inside the gantry 2 and are fixedly connected to the base 1. The sides of the two support blocks 60 are close to their respective sides of the gantry 2 and are in contact with the inner wall of the gantry 2 to improve the stability of the motor under test 8 during testing. The fixing ring 61 has an annular part and a fixing connection part. The annular part is semi-circular, and the fixing connection part is fixed to the outer wall of the annular part. The annular part is used to fit around the outside of the motor under test 8 to fix the motor under test 8. The fixing connection part is detachably connected to the support block 60. The fixing connection part is provided with a screw hole, and the support block 60 is also provided with a screw hole. A stud 62 is inserted into the screw holes on the fixing connection part and the support block 60 to screw the support block 60 and the fixing connection part together, thereby fixing the motor under test 8.
[0045] The support block 60 has multiple screw holes arranged side by side. For example, if there are two rows of screw holes, when the screw holes on the fixed connection part mate with the screw holes in different rows on the support block 60, the mounting chambers formed by the two opposing annular parts are of different sizes, thus allowing different sizes of motors to be fixed and enabling performance testing of various motors.
[0046] Of course, there are at least two support blocks 60 and at least two fixing rings 61. In this embodiment, there are two support blocks 60 and four fixing rings 61, with the four fixing rings 61 docking in pairs.
[0047] refer to Figure 3 and Figure 4 and combined Figure 1 A load testing assembly 4 is provided on one side of the fixed structure 6. The load testing assembly 4 can test the low-load performance, normal-load performance, and high-load performance of the motor under test 8. The load testing assembly 4 includes a fixed support ring 40 and rotating disks 41. There are multiple rotating disks 41, which are housed in the inner space of the fixed support ring 40, and the outer circumferential surfaces of the multiple rotating disks 41 are in contact with the fixed support ring 40. The multiple rotating disks 41 can be arranged at intervals or with their end faces connected. Each rotating disk 41 has a insertion hole 411 at its center to facilitate connection with the output shaft of the motor under test 8. The friction between the rotating disks 41 and the fixed support ring 40 forms a load. The connection of the output shaft of the motor under test 8 to different numbers of rotating disks 41 represents the motor under test 8 driving different loads.
[0048] Since the output shaft of the motor under test 8 is mostly cylindrical, it is not convenient to directly form a reliable connection with the rotating disk 41. Therefore, a docking structure 7 is provided between the output shaft of the motor under test 8 and the rotating disk 41. The docking structure 7 connects the rotating disk 41 and the output shaft of the motor under test 8. The two ends of the docking structure 7 are detachably connected to the rotating disk 41 and the output shaft of the motor under test 8, respectively. The docking structure 7 can also take many forms, and the examples listed in this embodiment are not intended to limit the docking structure 7.
[0049] In this embodiment, the docking structure 7 includes a mounting sleeve 70 and a plug-in block 71. One end of the mounting sleeve 70 can be clamped onto the output shaft of the motor 8 under test, and the other end of the mounting sleeve 70 is fixedly connected to the plug-in block 71. The plug-in block 71 can be inserted into the plug-in hole 411. When the plug-in block 71 is inserted into the plug-in hole 411, the rotating disk 41 and the plug-in block 71 will not rotate relative to each other, so as to form a reliable connection. For example, the plug-in block 71 is prismatic, and the plug-in hole 411 is also a prismatic hole, the size of which is adapted to the prismatic plug-in block 71. For example, the plug-in block 71 is cylindrical, and its outer wall is provided with multiple spaced limiting grooves 711. These grooves are axially spaced. A protruding limiting block 412 is provided on the wall of the plug-in hole 411. The limiting block 412 is fitted into the limiting groove 711. When the limiting block 412 is engaged in the limiting groove 711, the plug-in block 71 and the rotating disk 41 will not rotate relative to each other, thus ensuring the accuracy of the load test results for the motor under test 8. Of course, the limiting block 412 can slide along the limiting groove 711, allowing rotating disks 41 at different positions to connect with the plug-in block 71, thereby adjusting the number of rotating disks 41 driven by the motor under test 8 and detecting the performance of the motor under test 8 under different loads.
[0050] Since the motor under test 8 is fixed on the fixed ring 61 and cannot move on its own, it is necessary to use the adjustment component 5 to adjust the movement of the load test component 4 in order to test the different load performance of the motor under test 8, so as to control the output shaft of the motor under test 8 to connect with different numbers of rotating disks 41.
[0051] Refer again Figure 1The adjustment component 5 includes a moving block 50, a lead screw 51, and a drive component 52. The drive component 52 can be a servo motor. The moving block 50 is provided with a through threaded hole, and the lead screw 51 passes through the through threaded hole and is threadedly connected. The base 1 is provided with a guide groove 10, and neither end of the guide groove 10 penetrates the base 1. The lead screw 51 and the moving block 50 are located in the guide groove 10. The end of the lead screw 51 near the servo motor passes through the base 1 and extends to the outside of the base 1. The end of the lead screw 51 away from the servo motor is connected to the base 1. Both ends of the lead screw 51 are fitted with bearings, which enable rotatable connection with the base 1. The output shaft of the servo motor is connected to the exposed end of the lead screw 51 through a shaft connector. When the servo motor starts, the lead screw 51 rotates. Since the lead screw 51 itself cannot move, the moving block 50 threaded onto the lead screw 51 slides along the guide groove 10. The sliding of the moving block 50 drives the fixed support ring 40 connected to it to move. The movement of the fixed support ring 40 drives the rotating disk 41 to move, thereby connecting different numbers of rotating disks 41 to the plug-in block 71.
[0052] Using a lead screw 51 and a servo motor to drive the rotating disk 41 not only allows for precise control of the position of the rotating disk 41, but also enables the connection or disconnection of the rotating disk 41 from the plug block 71 through the forward and reverse rotation of the servo motor. The connection is precise and reliable, and no manual operation is required.
[0053] Of course, in other embodiments, the movement of the rotating disk 41 can also be achieved using other structural forms, and there are no limitations on this.
[0054] refer to Figure 5 and combined Figure 1 The spray assembly 3 is used to spray the motor 8 under test to simulate rain and wading through water. The spray assembly 3 includes a water tank 30, a water supply pipe 31, a connecting pipe 32, a nozzle 33, and a support 34. The water tank 30 is located on top of the gantry 2 and stores water and a water pump. One end of the water supply pipe 31 is connected to the water pump in the water tank 30, and the other end of the water supply pipe 31 is connected to the connecting pipe 32. When the water pump is started, it can pump water from the water tank 30 to the water supply pipe 31, and then the water flows to the connecting pipe 32. The connecting pipe 32 has multiple connection holes on its wall. The nozzle 33 is connected to the connecting pipe 32 through the connection holes. Water in the connecting pipe 32 is sprayed out from the nozzle 33, and the sprayed water or water mist falls onto the motor 8 under test to achieve the waterproof performance test.
[0055] The water supply pipe 31 is directly fixed to the gantry frame 2, and the connecting pipe 32 is fixed to the gantry frame 2 through the bracket 34. The bracket 34 can be a columnar buckle, with one end of the columnar buckle being a column and the other end being a buckle. That is, the buckle is fixed to one end of the column, and one end of the buckle is snapped onto the connecting pipe 32. The end of the column away from the buckle is fixed to the gantry frame 2, thereby suspending the connecting pipe 32 and the nozzle 33. The buckle here is a common device on the market, and its structure will not be described in detail.
[0056] Since there can be multiple connection holes on the connecting pipe 32, there can also be multiple nozzles 33. Multiple nozzles 33 can spray water from different directions onto the motor 8 under test.
[0057] Optionally, if the orientation of the connecting hole is different, the orientation of the multiple nozzles 33 connected to the connecting hole will also be different, which will result in the different water spraying directions of the multiple nozzles 33.
[0058] In addition, multiple connecting pipes 32 can be arranged so that connecting pipes 32 and nozzles 33 are installed on the top, bottom and sides of the gantry 2 to simulate the situation of rain or ground water splashing onto the motor 8 under test. When multiple connecting pipes 32 are arranged, the multiple connecting pipes 32 and the water supply pipe 31 can be connected by tee joints or straight joints.
[0059] Continue to refer to Figure 5 A temperature detector 9 is installed on the gantry 2. The temperature detector 9 can detect the temperature change of the motor under test 8, determine the temperature of the motor under test 8 under different test environments, and thus infer the various performance characteristics of the motor under test 8.
[0060] In this embodiment, the temperature detector 9 is a thermal imaging detector. The thermal imaging detector can detect the temperature change and heating location of the motor under test 8 in real time, so as to clearly observe the performance change of the motor under test 8 and determine whether the motor under test 8 is in a normal state.
[0061] Of course, in other embodiments, other testing instruments may be used to test the performance parameters of the motor 8 under test, which is not limited here.
[0062] Working principle of the motor performance testing device according to this utility model embodiment:
[0063] When testing the motor 8 under test, first place the entire device on a flat surface, then form a suitable mounting chamber according to the size of the motor 8 under test, and fix the motor 8 under test inside the corresponding fixing ring 61; connect the power supply to the motor 8 under test and perform an idle test. The thermal imaging detector can detect the temperature change of the motor 8 under test and transmit the detection data back; when waterproof performance testing is required, start the water pump, and the water in the water tank 30 flows through the water supply pipe 31 and the connecting pipe 32 and is sprayed out from the nozzle 33 to simulate rain or water splashing on the ground. During the spraying process, the motor 8 under test can be stopped or started. Under load conditions, the thermal imaging detector can also detect temperature changes in the motor under test (MUT) 8. When load capacity testing is required, first connect the mounting housing 70 to the output shaft of the MUT 8, then start the servo motor to drive the lead screw 51 to rotate, causing the rotating disk 41 to move. The plug block 71 is inserted into the plug hole 411 of the rotating disk 41 to load the motor under test 8. After confirming that the load matches the predetermined load, start the MUT 8. The MUT 8 drives the rotating disk 41 connected to it to rotate, performing the load capacity test. Connecting the MUT 8 to different numbers of rotating disks 41 represents different levels of load. Of course, during the load capacity test, water can also be sprayed onto the MUT 8 to test both waterproofing and load performance. The thermal imaging detector can also detect temperature changes in the MUT 8 during this test.
[0064] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
