Description

Technical Field

[0001] This invention belongs to the field of motor testing technology, specifically relating to a testing device for new energy vehicle motors. Background Technology

[0002] To improve the reliability of new energy vehicles and ensure their normal operation, it is generally necessary to test the motors of new energy vehicles in order to improve the user's driving experience.

[0003] Currently, most testing devices for new energy vehicle motors place them on a testing platform and connect them to a tow motor for testing. However, since vehicles encounter numerous uphill and downhill sections during actual use, existing tow motor testing platforms cannot simulate the complex conditions of electric vehicles on real roads, thus failing to improve the accuracy and applicability of the tests. Furthermore, to facilitate motor installation, most tow motor testing platforms have their mounting platforms directly exposed to the external environment. External environmental factors and interference make it difficult for the testing platform to effectively receive noise from electric vehicle motors when simulating complex road conditions, which is not ideal for actual testing. Summary of the Invention

[0004] The purpose of this invention is to provide a testing device for electric motors in new energy vehicles to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A new energy vehicle motor testing device includes a testing plate. Rotating rods are symmetrically mounted on both sides of the testing plate near its bottom. A side plate is provided on the side of the rotating rod away from the testing plate. Symmetrical through holes are formed on the side walls of the side plates near both ends. A rotating shaft passes through the through holes and is connected to the rotating rod via a movable component. A base plate connects the two side plates and is located below the testing plate. A double-headed hydraulic cylinder is fixedly mounted at the bottom center of the base plate. Each output end of the double-headed hydraulic cylinder is connected to a connecting plate. Inclined insert plates are fixedly mounted on the side walls of the connecting plates near both ends, and the inclined insert plates are located below the testing plate.

[0006] Preferably, the movable component includes a plug rod, a second fitting groove is provided at one end of the rotating rod near the rotating shaft, a first fitting groove is provided at one end of the rotating shaft near the rotating rod, a plug rod is fixedly installed on the side wall of the second fitting groove, an insertion hole is provided on the side wall of the first fitting groove, the rotating rod is fitted and connected to the rotating shaft, and the plug rod is inserted into the insertion hole.

[0007] Preferably, rollers are symmetrically installed on both sides of the detection plate near its bottom, and an inclined groove is formed on the top surface of the inclined insert plate. A slot is formed at the bottom of the inclined groove away from the inner wall of the connecting plate. The slot has an arc-shaped structure, and the rollers slide and fit inside the slot.

[0008] Preferably, the rotating shaft has a T-shaped structure, and a bearing is fixedly installed inside the perforation. The rotating shaft passes through the bearing and is connected to the rotating rod.

[0009] Preferably, a transmission frame is rotatably provided on the detection plate. The transmission frame has a U-shaped structure. An arc-shaped strip is slidably provided on the top of the inner wall of the transmission frame. A sliding hole is provided on the arc-shaped strip. Sliding grooves are symmetrically provided on both sides of the inner wall of the sliding hole. A sliding plate is slidably provided inside the sliding groove. A microphone is connected to the side of the sliding plate closest to the detection plate.

[0010] Preferably, guide grooves are symmetrically provided on both sides of the inner wall of the transmission frame, and guide rods are fixedly installed inside the guide grooves. An auxiliary plate is symmetrically installed on the side of the arc-shaped strip closest to the transmission frame. An auxiliary hole is provided on the auxiliary plate, and the auxiliary plate is slidably fitted inside the guide groove. The guide rod passes through the auxiliary hole on the auxiliary plate.

[0011] Preferably, an adjustment hole is provided at the center of the top of the slide plate, a rubber ring is fixedly installed on the inner wall of the adjustment hole, and a sliding rod is inserted through the adjustment hole. The sliding rod has a T-shaped structure, and grooves are provided at equal intervals on the outer wall of the sliding rod. The rubber ring is fitted inside the grooves, and the microphone is fixedly installed on the side end face of the sliding rod near the detection plate.

[0012] Preferably, an adjustment groove is fixedly provided on the top of the inner wall of the transmission frame. The adjustment groove has an arc-shaped structure, and the sliding rod is slidably disposed inside the adjustment groove.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] (1) The present invention is equipped with a double-headed hydraulic cylinder, an inclined insert plate and a detection plate. After the motor is installed, the double-headed hydraulic cylinder drives the inclined insert plate to squeeze the detection plate from one side through the connecting plate, causing the detection plate to slide on the base plate, so that the rotating rod on one side is engaged with the rotating shaft. As the inclined insert plate continues to squeeze, the detection plate rotates between the two side plates, thereby adjusting the tilt angle of the motor. This, in conjunction with the towing motor, simulates the tilting effect of a car going up and down a slope, improving the accuracy of the detection.

[0015] (2) The present invention is equipped with a transmission frame, an arc strip and a microphone. After the fixed installation is completed, since the transmission frame is not closed at this time, the position of the microphone can be flexibly adjusted by pulling the arc strip and the slide plate on the arc strip and sliding it on the transmission frame and the arc strip. Then, the transmission frame is rotated to close and cover the electric vehicle motor, ensuring that the microphone can still obtain a relatively high sound reception effect when dealing with electric vehicle motors of different models, sizes and shapes, which is convenient for actual testing.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Please see Figures 1-6 As shown, the present invention provides the following technical solution: A new energy vehicle motor testing device includes a test plate 3. Rotating rods 22 are symmetrically installed on both sides of the test plate 3 near its bottom. Side plates 8 are provided on the side of the rotating rods 22 away from the test plate 3. Symmetrical through holes 20 are provided on the side walls of the side plates 8 near both ends. Rotating shafts 4 pass through the through holes 20. The rotating shafts 4 are connected to the rotating rods 22 via movable components. A base plate 13 is connected between the two side plates 8. The base plate 13 is located below the test plate 3, and a double-headed hydraulic cylinder 6 is fixedly installed at the center of the bottom of the base plate 13. The output ends of the head hydraulic cylinder 6 are all connected to the connecting plate 7. The inclined insert plate 5 is fixedly installed on the side wall of the connecting plate 7 near both ends. The inclined insert plate 5 is located below the detection plate 3. The movable component includes the insert rod 24. The rotating rod 22 has a second fitting groove 31 at one end near the rotating shaft 4. The rotating shaft 4 has a first fitting groove 21 at one end near the rotating rod 22. The insert rod 24 is fixedly installed on the side wall of the second fitting groove 31. The first fitting groove 21 has an insertion hole 23 on the side wall. The rotating rod 22 is fitted and connected to the rotating shaft 4. The insert rod 24 is inserted into the insertion hole 23.

[0027] With the above technical solution, the electric vehicle motor is fixedly installed on the detection plate 3 during use. Then, by adjusting the double-headed hydraulic cylinder 6, the connecting plate 7 is moved horizontally, causing the inclined insert plate 5 on one side to gradually squeeze the side wall of the detection plate 3, pushing the detection plate 3 and making it slide horizontally on the base plate 13. As the detection plate 3 slides, the rotating shaft 4 and the rotating rod 22 on one side come into contact with each other, causing the insert rod 24 on the same side to be inserted into the interior of the insertion hole 23, while the insert rod 24 on the other side is disengaged from the interior of the insertion hole 23. As the inclined insert plate 5 continues to slide, the inclined surface of the inclined insert plate 5 gradually pushes the bottom of the detection plate 3, causing the detection plate 3 to tilt and rotate with the fitted rotating shaft 4 and the rotating rod 22 as the center, thereby adjusting the tilt angle of the electric vehicle battery. This, combined with the auxiliary motor, simulates the tilting effect of a car going up and down a slope, improving the accuracy of the detection.

[0028] As the detection plate 3 rotates, the insertion rod 24 is inserted into the insertion hole 23. The interlocking connection ensures that the connection between the rotating shaft 4 and the rotating rod 22 on the same side will not disengage during rotation, ensuring smooth tilting and stable rotation, and facilitating the use of the detection.

[0029] Furthermore, rollers 15 are symmetrically installed on both sides of the detection plate 3 near its bottom. An inclined groove 9 is provided on the top surface of the inclined insert plate 5. A slot 14 is provided at the bottom of the inclined groove 9 away from the inner wall of the connecting plate 7. The slot 14 has an arc-shaped structure. The rollers 15 slide and fit inside the slot 14. The rotating shaft 4 has a T-shaped structure. A bearing 19 is fixedly installed inside the through hole 20. The rotating shaft 4 passes through the bearing 19 and is connected to the rotating rod 22.

[0030] Please refer to Figure 4 Since the roller 15 is slidably set inside the slot 14, it can be connected by fitting and, together with the inclined insert plate 5, squeeze and push the detection plate 3. After the insert rod 24 is inserted into the insertion hole 23, the detection plate 3 cannot move further due to the obstruction of the rotating shaft 4. At this time, the inclined insert plate 5 continues to squeeze, causing the roller 15 to move into the inclined slide groove 9, and then gradually push one end of the detection plate 3 to move it upward, adjusting the tilt angle of the detection plate 3. The roller 15 is used to increase the smoothness of the detection plate 3 when tilting, which is convenient for actual use.

[0031] Furthermore, a transmission frame 1 is rotatably mounted on the detection plate 3. The transmission frame 1 has a U-shaped structure. An arc-shaped strip 12 is slidably mounted on the top of the inner wall of the transmission frame 1. A sliding hole 17 is opened on the arc-shaped strip 12. Sliding grooves 16 are symmetrically opened on both sides of the inner wall of the sliding hole 17. A sliding plate 29 is slidably mounted inside the sliding groove 16. A microphone 2 is connected to the side of the sliding plate 29 near the detection plate 3. Guide grooves 27 are symmetrically opened on both sides of the inner wall of the transmission frame 1. A guide rod 26 is fixedly installed inside the guide groove 27. An auxiliary plate 25 is symmetrically mounted on the side of the arc-shaped strip 12 near the transmission frame 1. An auxiliary hole 28 is opened on the auxiliary plate 25. The auxiliary plate 25 is slidably fitted inside the guide groove 27. The guide rod 26 passes through the auxiliary hole 28 and is mounted on the auxiliary plate 25.

[0032] Please refer to Figures 1-3 and Figure 7 -and Figure 8 After the electric vehicle motor is installed, the transmission frame 1 is not closed, and the auxiliary plate 25 slides through the guide rod 26 inside the guide groove 27. The arc strip 12 can be manually moved to slide inside the transmission frame 1. Then, the slide plate 29 is manually moved to make the microphone 2 slide inside the sliding groove 16 on the sliding hole 17. After the microphone 2 moves to the predetermined position, the transmission frame 1 is rotated to cover the electric vehicle motor, blocking the linkage between the electric vehicle motor and the outside world. With the arc strip 12 and the slide plate 29, the microphone 2's sound reception effect is increased when the electric vehicle motor is tilted. Since the microphone 2 has a large range of movement and is not directly fixed to the electric vehicle battery, it can be adapted to electric vehicle motors of different models, sizes and shapes, which is convenient for actual testing.

[0033] Furthermore, an adjustment hole 30 is provided at the center of the top of the slide plate 29. A rubber ring 18 is fixedly installed on the inner wall of the adjustment hole 30, and a sliding rod 11 passes through the inside of the adjustment hole 30. The sliding rod 11 has a T-shaped structure, and grooves are provided at equal intervals on the outer wall of the sliding rod 11. The rubber ring 18 is fitted into the groove. The microphone 2 is fixedly installed on the side end face of the sliding rod 11 near the detection plate 3. An adjustment groove 10 is fixedly provided at the top of the inner wall of the transmission frame 1. The adjustment groove 10 has an arc-shaped structure, and the sliding rod 11 is slidably disposed inside the adjustment groove 10.

[0034] Please refer to Figure 3 and Figure 8 Since the microphone 2 is fixedly mounted on the sliding rod 11, when dealing with electric vehicle batteries with smaller diameters, the sliding rod 11 can be pulled to slide inside the adjustment hole 30 on the slide plate 29. The rubber ring 18 is connected to different grooves to limit and fix the sliding rod 11, thereby adjusting the distance between the microphone 2 and the electric vehicle battery. In conjunction with the arc strip 12 and the slide plate 29, the sound reception effect of the microphone 2 is further improved, and the accuracy of the final detection data is improved.

[0035] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
