Description

Technical Field

[0001] The present invention belongs to the field of motor testing, and in particular relates to a new energy vehicle motor testing device. Background Art

[0002] New energy vehicles refer to vehicles that use unconventional automotive fuels as their power source and integrate advanced technologies in vehicle power control and drive to form vehicles with advanced technical principles, new technologies, and new structures. Traditional new energy vehicles generally use batteries to power the motor for driving.

[0003] The motor in a new energy vehicle is the core of the entire vehicle. In order to ensure the safety of the vehicle, the motor needs to be tested for various indicators before leaving the factory, including motor life test, motor high-load operation test, noise test, etc.

[0004] Traditional testing equipment can generally only test a single function of the motor. After each test, the motor needs to be transferred to other test structures for testing. This makes the testing process more step-by-step, wastes time, and reduces test efficiency.

[0005] To this end, the present invention provides a new energy vehicle motor testing device. Summary of the Invention

The motor to be tested is mounted on the placement plate, and the placement plate and motor are driven to move on the guide rail by the driving module, so that the motor can be installed and removed at a location far away from the test point. When the placement plate and motor are moved to the side of the decibel detection module, the motor is first connected to the connecting assembly, and the pressing assembly is used to press the outer surface of the motor to ensure that the motor does not vibrate violently during high load. Then, the driving end of the motor is connected using the connecting assembly. The connecting assembly can detect the speed of the motor. At the same time, during the operation of the motor, the decibel detection module can detect the decibel value of the surrounding area, thereby detecting the noise value of the motor during operation.

[0008] Preferably, the placement plate consists of an upper plate and a lower plate, the top of the lower plate is fixedly connected to a top column, a disc-shaped movable groove is provided on the bottom surface of the lower plate, a plurality of return springs are fixedly connected between the inner wall of the movable groove and the outer side of the top column, a movable groove is provided on the top inner wall of the movable groove, a disc is fixedly connected to the top of the top column, and the disc is clamped in the movable groove, a vibration measuring instrument 1 is fixedly connected to the surface of the upper plate, a locking assembly is connected between the upper and lower plates, and the locking assembly is used to fix the upper and lower plates. Before the motor runs, the locking assembly can be released first to release the lock between the upper and lower plates, so that the upper plate can move freely in the horizontal direction. At this time, by collecting the values ​​of the vibration measuring instrument 1, the horizontal vibration amplitude values ​​generated by the motor at different powers can be obtained.

[0009] Preferably, the guide rail is arranged in sections, and a reinforcement frame is fixedly connected to the bottom of the guide rail near one end of the decibel detection module, and a plurality of spring telescopic rods are fixedly connected to the bottom of the reinforcement frame. A second vibration measuring instrument is fixedly connected to the outer side of the lower plate. A groove is provided between the outer sides of the two sections of the guide rail, and a splicing block adapted to the groove is provided on the outer side of the groove. An electric telescopic rod 1 is connected to the outer side of the splicing block. When the placement plate is in a locked state, the splicing block is first moved away from the guide rail through the electric telescopic rod 1. At this time, the two sections of the guide rail are separated from each other, allowing the motor to start running. At this time, the guide rail, the placement plate and the motor are a whole. As a whole, the vibration generated by the motor makes the whole structure shake up and down, and the setting of the spring telescopic rod allows the structure to move up and down normally. At this time, the vibration measuring instrument 2 can be used to measure the amplitude of the up and down vibration generated by the motor during operation. Through this setting, the control variable is realized.

When the motor moves to the outside of the decibel detection module, the three hydraulic rods are started to extend, and the surface of the motor is pressed by three bent pressing arms, which firmly press the motor from different directions to ensure the firmness of the motor.

When docking the motor, the docking ring is used to socket the driving end of the motor, and the power of the docking ring is transmitted to the transmission disk through the tensile belt. The flexible tensile belt achieves a flexible transmission effect, so that the motor can transmit power outward normally during vibration.

[0014] Preferably, the counterweight assembly includes a plurality of counterweight columns, a plurality of assembly slots are provided at one end of the drive disc away from the transmission disc, the plurality of assembly slots are arranged in a circular shape with equal angles, and the number of the plurality of assembly slots is an even number, and a filling assembly is provided on the side of the drive disc away from the transmission disc, the filling assembly is used to fill the counterweight columns, and the weight of the drive disc can be continuously changed by filling the assembly slots with symmetrical counterweight columns in pairs through the filling assembly, thereby testing the power consumption, vibration and noise of the motor when driving objects of different masses.

[0015] Preferably, the driving disk is arranged in a truncated cone shape, the assembly groove is arranged in a centrifugal inclined shape, the end of the counterweight column is made of magnetic material, and the bottom of the assembly groove is made of magnetizable metal material.

A connecting component is provided on one side of the placement plate 2, and the connecting component is used to connect to the output end of the motor and measure the output speed. A pressing component is provided above the placement plate 2, and the pressing component is used to firmly fix the motor above the placement plate 2. Two decibel detection modules 4 are provided on the outside of the placement plate 2;

[0030] During operation, the motor to be tested is installed on the mounting plate 2, and the mounting plate 2 and the motor are driven to move on the guide rail 6 by the driving module, so that the motor can be installed and disassembled at a place far away from the test point. When the mounting plate 2 and the motor are moved to the side of the decibel detection module 4, the motor is first connected to the connecting component, and the compression component is used to compress the outer surface of the motor to ensure that the motor does not vibrate violently during high load. Then, the driving end of the motor is connected using the connecting component. The connecting component can detect the speed of the motor. At the same time, during the operation of the motor, the decibel detection module 4 can detect the surrounding decibel value, thereby detecting the noise value of the motor during operation.

[0031] like Figures 3 and 4 As shown, the placement plate 2 consists of an upper plate 15 and a lower plate 16, the top of the lower plate 16 is fixedly connected to a top column 17, a disc-shaped movable groove 18 is provided on the bottom surface of the lower plate 16, a plurality of return springs 19 are fixedly connected between the inner wall of the movable groove 18 and the outer side of the top column 17, a movable groove is provided on the top inner wall of the movable groove 18, a disc is fixedly connected to the top of the top column 17, and the disc is clamped in the movable groove, a vibration measuring instrument 1 is fixedly connected to the surface of the upper plate 15, and a locking assembly is connected between the upper plate 15 and the lower plate 16, and the locking assembly is used to fix the upper plate 15 and the lower plate 16;

[0032] During operation, before the motor runs, the locking assembly can be released first to release the lock between the upper plate 15 and the lower plate 16, so that the upper plate 15 can move freely in the horizontal direction. At this time, by collecting the values ​​of the vibration measuring instrument, the horizontal vibration amplitude values ​​generated by the motor at different powers can be obtained.

[0033] like Figures 1 to 4 As shown, the guide rail 6 is arranged in sections, and a reinforcement frame 14 is fixed to the bottom of the guide rail 6 near one end of the decibel detection module 4. A plurality of spring telescopic rods 11 are fixed to the bottom of the reinforcement frame 14. A second vibration measuring instrument is fixed to the outer side of the lower plate 16. A groove is provided between the outer sides of the two sections of the guide rail 6. A splicing block 12 adapted to the groove is provided on the outer side of the groove, and an electric telescopic rod 1 is connected to the outer side of the splicing block 12.

[0034] During operation, when the placement plate 2 is in a locked state, the electric telescopic rod 1 is first used to move the splicing block 12 away from the guide rail 6. At this time, the two sections of the guide rail 6 are separated from each other, allowing the motor to start running. At this time, the guide rail 6, the placement plate 2 and the motor are a whole. The vibration generated by the motor makes the whole shake up and down. The setting of the spring telescopic rod 11 allows the structure to move up and down normally. At this time, the vibration measuring instrument 2 can be used to measure the amplitude of the up and down vibration generated by the motor during operation. Through this setting, the control variable is realized. During the motor vibration detection process, the vibration amount generated in the horizontal and vertical directions can be measured respectively. At the same time, the lock of the placement plate 2 and the lock of the guide rail 6 can be released at the same time, allowing the motor to shake freely in the vertical and horizontal directions, thereby more comprehensively detecting the various forms of vibration generated by the motor during operation.

[0035] like Figures 2 to 4 As shown, the locking assembly includes four locking arms 10, and the four corners of the placement plate 2 are provided with engaging grooves. Four electric telescopic rods are fixed to the interior of the lower plate 16, and the ends of the electric telescopic rods are fixed to the locking arms 10, and the locking arms 10 are adapted to the engaging grooves;

[0036] During operation, when it is necessary to release the locked state of the placement plate 2, the four electric telescopic rods are started to extend outward, allowing the locking arms 10 to protrude outward. At this time, the upper plate 15 and the lower plate 16 are unlocked, and the upper plate 15 can be moved at will. When it is necessary to lock, the electric telescopic rods are shortened, allowing the locking arms 10 to be inserted into the engaging grooves, which can lock the upper plate 15 and the lower plate 16, making the upper plate 15 unable to move. This arrangement makes the locking and unlocking processes extremely convenient.

[0037] like Figures 1 to 2 As shown, the compression assembly includes a hanger 5, which is located above the placement plate 2. Three hydraulic rods 9 are fixed to the bottom of the hanger 5, two of which are symmetrically arranged, and the other is inclined. The bottoms of the hydraulic rods 9 are all fixed with bent pressing arms 8. The top surface of the placement plate 2 is provided with multiple connecting slots 7.

[0038] During operation, after the motor is correctly placed on the mounting plate 2, the bottom of the motor is first fixed to the connecting slot 7 by bolts. When the motor moves to the outside of the decibel detection module 4, the three hydraulic rods 9 are started to extend, and the surface of the motor is pressed by three bent pressing arms 8, firmly pressing the motor from different directions to ensure the firmness of the motor. When detecting motor vibration, the pressing arm 8 does not need to be pressed.

[0039] like Figures 5 and 6As shown, the connection assembly includes a docking seat 1, a support seat 24 is fixedly connected to the top of the docking seat 1, the top of the support seat 24 is arranged in a circular ring shape, and the top inner ring of the support seat 24 is slidably connected to the driving disk 20, and a counterweight assembly is provided on the inner side of the driving disk 20, and the counterweight assembly can change the weight of the driving disk 20;

[0040] During operation, when the motor is in place, the output end of the motor is connected to the driving disk 20, so that the output of the motor acts on the driving disk 20. The driving disk 20 has a built-in speed measurement module that can detect the speed. At the same time, the counterweight assembly can continuously increase the mass of the driving disk 20, and the driving limit of the motor can be measured.

[0041] like Figures 5 and 6 As shown, a transmission disc 21 is fixedly connected to the side of the driving disc 20 close to the placement plate 2, and a docking ring 22 is provided on the side of the transmission disc 21 away from the driving disc 20. Two flexible tensile belts 23 are fixedly connected between the docking ring 22 and the transmission disc 21;

[0042] During operation, when docking the motor, the driving end of the motor is sleeved using the docking ring 22, and the power of the docking ring 22 is transmitted to the transmission disk 21 through the tensile belt 23. The flexible tensile belt 23 achieves a flexible transmission effect, allowing the motor to transmit power normally during vibration.

[0043] like Figures 5 and 6 As shown, the counterweight assembly includes a plurality of counterweight columns 28, and a plurality of assembly slots 29 are provided on one end of the drive disc 20 away from the transmission disc 21. The plurality of assembly slots 29 are arranged in a circular shape with equal angles, and the number of the plurality of assembly slots 29 is an even number. A filling assembly is provided on one side of the drive disc 20 away from the transmission disc 21, and the filling assembly is used to fill the counterweight columns 28;

[0044] During operation, by filling the assembly with two symmetrical counterweight columns 28 into the assembly slot 29, the weight of the drive disc 20 can be continuously changed, thereby testing the power consumption, vibration and noise of the motor when driving objects of different masses.

[0045] like Figures 5 and 6 As shown, the driving disk 20 is arranged in a truncated cone shape, the assembly groove 29 is arranged in a centrifugal inclined shape, the end of the counterweight column 28 is a magnetic material, and the bottom of the assembly groove 29 is a magnetizable metal material. During operation, the inclined setting of the assembly groove 29 is combined with the filled counterweight column 28 to generate an outward inclined centrifugal force during the rotation process, so that the counterweight column 28 will not be thrown out during the rotation process, and under the adsorption effect of the magnet, the counterweight column 28 will not fall off even when it is not rotating.

[0046] like Figures 5 and 6As shown, the filling assembly includes an inclined addition pipe 27, an addition box 25 is fixedly connected to the upper outer side of the addition pipe 27, and a hydraulic rod 26 is fixedly connected to the end of the addition pipe 27 away from the drive disk 20. The output end of the hydraulic rod 26 is slidably connected to the inside of the addition pipe 27, and the hydraulic rod 26 is fixedly connected to the docking seat 1. During operation, the counterweight column 28 in the addition box 25 will continuously move into the addition pipe 27 under the action of gravity, and then be squeezed into the assembly groove 29 under the ejection of the hydraulic rod 26. Through this arrangement, continuous filling of the counterweight column 28 is achieved.

[0047] During operation, the motor to be tested is installed on the mounting plate 2, and the mounting plate 2 and the motor are driven to move on the guide rail 6 by the driving module, so that the motor can be installed and disassembled at a place far away from the test point. After the mounting plate 2 and the motor are moved to one side of the decibel detection module 4, the motor is first connected to the connecting component, and the compression component is used to compress the outer surface of the motor to ensure that the motor does not vibrate violently during high load. Then, the driving end of the motor is connected using the connecting component. The connecting component can detect the speed of the motor. At the same time, during the operation of the motor, the decibel detection module 4 can detect the decibel value of the surrounding area, thereby detecting the noise value of the motor during operation;

[0048] Before the motor is running, the locking assembly can be released to release the lock between the upper plate 15 and the lower plate 16, so that the upper plate 15 can move freely in the horizontal direction. At this time, by collecting the values ​​of the vibration measuring instrument, the horizontal vibration amplitude values ​​generated by the motor at different powers can be obtained;

[0049] When the placement plate 2 is in the locked state, the electric telescopic rod 1 is first used to move the splicing block 12 away from the guide rail 6. At this time, the two sections of the guide rail 6 are separated from each other, allowing the motor to start running. At this time, the guide rail 6, the placement plate 2 and the motor are a whole. The vibration generated by the motor makes the whole shake up and down. The setting of the spring telescopic rod 11 allows the structure to move up and down normally. At this time, the vibration measuring instrument 2 can be used to measure the amplitude of the up and down vibration generated by the motor during operation. Through this setting, the control variable is realized. During the motor vibration detection process, the vibration amount generated in the horizontal and vertical directions can be measured respectively. At the same time, the lock of the placement plate 2 and the lock of the guide rail 6 can be released at the same time, allowing the motor to shake freely in the vertical and horizontal directions, thereby more comprehensively detecting the various forms of vibration amount generated by the motor during operation;

[0050] When the locking state of the placement plate 2 needs to be released, the four electric telescopic rods are started to extend outward, so that the locking arms 10 protrude outward. At this time, the upper plate 15 and the lower plate 16 are unlocked, and the upper plate 15 can be moved freely. When it is necessary to lock, the electric telescopic rods are shortened, so that the locking arms 10 are inserted into the engaging grooves, and the upper plate 15 and the lower plate 16 can be locked, so that the upper plate 15 cannot move. This arrangement makes the locking and unlocking processes extremely convenient.

[0051] After the motor is correctly placed on the mounting plate 2, first fix the bottom of the motor to the connecting slot 7 with bolts. When the motor moves to the outside of the decibel detection module 4, start the three hydraulic rods 9 to extend, and press the surface of the motor through the three bent pressing arms 8, firmly pressing the motor from different directions to ensure the firmness of the motor. When detecting the vibration of the motor, the pressing arms 8 do not need to be pressed;

[0052] When the motor is in place, connect the output end of the motor to the drive disc 20, so that the output of the motor acts on the drive disc 20. The drive disc 20 has a built-in speed measurement module that can detect the speed. At the same time, the counterweight component can continuously add mass to the drive disc 20 to measure the driving limit of the motor.

[0053] When docking the motor, the driving end of the motor is sleeved with the docking ring 22, and the power of the docking ring 22 is transmitted to the transmission disc 21 through the tensile belt 23. The flexible tensile belt 23 achieves a flexible transmission effect, allowing the motor to transmit power normally during vibration.

[0054] By filling the assembly with two symmetrical counterweight columns 28 in the assembly slot 29, the weight of the drive disc 20 can be continuously changed, thereby testing the power consumption, vibration and noise of the motor when driving objects of different masses;

[0055] The inclined arrangement of the assembly slot 29 allows the loaded counterweight column 28 to generate an outward inclined centrifugal force during the rotation process, so that the counterweight column 28 will not be thrown out during the rotation process. Under the adsorption effect of the magnet, the counterweight column 28 will not fall off even when it is not rotating.

[0056] The counterweight column 28 in the adding box 25 will continuously move into the adding pipe 27 under the action of gravity, and then be squeezed into the assembly groove 29 under the ejection of the hydraulic rod 26. Through this arrangement, the counterweight column 28 can be continuously loaded.
