Description

Technical Field

[0001] This invention relates to the field of new energy vehicle drive motor testing technology, specifically a new energy vehicle drive motor phase loss detection device. Background Technology

[0002] The power source of new energy vehicles is the conversion of electrical energy into mechanical energy through a drive motor. New energy vehicles typically have one or two motors. The drive motor is one of the three core components of a new energy vehicle. The motor drive control system is the main execution structure in the operation of a new energy vehicle. Its drive characteristics determine the main performance indicators of the vehicle. It is an important component of electric vehicles. The motor drive system mainly consists of an electric motor, a power converter, a controller, various detection sensors, and a power supply.

[0003] When a motor is missing a phase, if the drive motor is powered on and started, it will generally make a "humming" sound and the motor speed will increase slowly. At the same time, the vibration of the drive motor will also increase. When the load driven by the motor is heavy, it will not reach the specified speed when starting, or it may not even start. If this state continues for a long time, the motor will overheat due to the long-term high current, and in severe cases, it will smoke, catch fire and burn.

[0004] The prior art provides a "rapid detection device for three-phase power phase loss," with publication number CN213658856U. This application includes a housing with a lampshade connected to the top. Four terminal block positioning holes are provided at the bottom of the housing. From top to bottom, the housing is sequentially equipped with an indicator circuit board, a main circuit board, a terminal block circuit board, and four terminals. Three indicators are installed on the indicator circuit board. The indicator circuit board and the terminal block circuit board are electrically connected to the main circuit board. The three indicators correspond to the three live wires, and the four terminals correspond to the three live wires and one neutral wire, respectively. All four terminals are electrically connected to the terminal block circuit board. The four independent terminals are respectively installed in the terminal block positioning holes. The main circuit board integrates a control circuit for controlling the indicators to issue prompts. This device achieves intuitive, rapid, and efficient three-phase power phase loss detection without the need for calculation, significantly improving detection efficiency.

[0005] Although existing technologies meet users' needs to a certain extent, there are still some defects in their use. Specific problems are as follows: when the drive motor loses a phase, the vibration increases, there are abnormal noises, the temperature rises, and the current increases. Conventional testing involves detecting the voltage of the drive motor, and voltage detection determines whether a phase is lost based on whether the circuit forms a loop. This cannot detect the physical factors of the drive motor and cannot further confirm whether the drive motor is missing a phase. Therefore, the phase loss detection of new energy drive motors has certain defects.

[0006] To address the aforementioned issues, we have made improvements and proposed a phase loss detection device for drive motors in new energy vehicles. Summary of the Invention

[0021] Compared with the prior art, the present invention provides a phase loss detection device for a new energy vehicle drive motor, which has the following beneficial effects:

[0022] 1. This new energy vehicle drive motor phase loss detection device uses a multimeter to drive a limit bar downwards. The limit bar is inserted into the test bracket from top to bottom until the multimeter is installed inside the test bracket. Then, a fixing clip is clamped onto the surface of the terminal block to detect the voltage of the drive motor body. The voltage is transmitted to the data display screen, which displays the voltage data of the drive motor body. This device can measure the voltage value of the drive motor in the new energy vehicle and determine whether there is a phase loss phenomenon in the drive motor.

[0023] 2. This new energy vehicle drive motor phase loss detection device utilizes the vibration of the drive motor body to move the clamping detection seat.

Detailed Implementation

[0035] 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.

[0036] Example 1

[0037] Please see Figure 1 , 6 7 is the first embodiment of the present invention. This embodiment provides a phase loss detection device for a new energy vehicle drive motor, including a detection device body 1. The detection device body 1 includes a detection fixing platform 101. Supporting legs 102 are fixedly connected to the front and back sides of the bottom of the detection fixing platform 101. Supporting baffles 103 are fixedly connected to the inner side of the supporting baffles 103 laterally. Vibration display mechanisms 2 are fixedly connected to the front and back sides of the top of the detection fixing platform 101.

[0038] The vibration display mechanism 2 includes a fixed stop 201. The bottom of the fixed stop 201 is fixedly connected to the top of the detection fixed platform 101. The fixed stop 201 is located on the front and back sides of the fixed base platform 501. A supporting movable shaft 202 is fixedly connected to the top of the inner cavity of the fixed stop 201. A clamping detection seat 203 is movably connected to the surface of the supporting movable shaft 202. A transmission cross plate 209 is fixedly connected to the side of the clamping detection seat 203 away from the fixed stop 201. A connecting column 20 is movably connected to the inner cavity of the transmission cross plate 209. 10. A transmission vertical plate 207 is fixedly connected to the left side of the connecting column 2010. A support rotating column 204 is movably connected to the top of the inner cavity of the transmission vertical plate 207. A support back frame 208 is fixedly connected to the left side of the support rotating column 204. The bottom of the support back frame 208 is fixedly connected to the top of the detection fixed platform 101. A vibration value pointer 205 for indicating vibration value is fixedly connected to the top of the transmission vertical plate 207. A vibration value dial 206 for displaying the magnitude of vibration value is fixedly connected to the top of the support back frame 208.

[0039] Specifically, a guide groove 2012 is provided on one side of the inner cavity of the transmission horizontal plate 209. The edge of the guide groove 2012 is set in a semi-circular structure. The diameter of the guide groove 2012 is larger than the diameter of the connecting column 2010, and the inner wall of the guide groove 2012 is movably connected to the surface of the connecting column 2010. Through the setting of the guide groove 2012, the transmission horizontal plate 209 can slide smoothly on the surface of the connecting column 2010, thereby pushing the connecting column 2010 to rotate, thereby linking the transmission vertical plate 207 to rotate, and thus amplifying the vibration amplitude of the drive motor body 401.

[0040] Specifically, a limiting plate 2011 is fixedly connected to the right side of the connecting column 2010. The cross-sectional area of ​​the left side of the limiting plate 2011 is larger than the cross-sectional area of ​​the right side of the connecting column 2010. The vibration value dial 206 is located to the left of the vibration value pointer 205. The limiting plate 2011 is used to limit the position of the transmission horizontal plate 209, preventing the transmission horizontal plate 209 from detaching from the surface of the connecting column 2010 during the sliding process, thereby ensuring the stability of the transmission horizontal plate 209 during operation.

[0041] Specifically, one end of the clamping detection seat 203 is set with an inclined structure, and one side of the clamping detection seat 203 is set with a concave structure. One side of the clamping detection seat 203 is clamped to the surface of the vibration transmission seat 405. By setting the clamping detection seat 203 with an inclined structure, the vibration transmission seat 405 can be clamped, thereby stably transmitting the vibration amplitude of the drive motor body 401.

[0042] The specific implementation of this embodiment is as follows: The clamping detection seat 203 is clamped on the surface of the vibration transmission seat 405. The vibration of the drive motor body 401 causes the clamping detection seat 203 to move. The clamping detection seat 203 rotates around the support movable shaft 202. The rotation of the support movable shaft 202 drives the transmission horizontal plate 209 to rotate. The transmission horizontal plate 209 slides on the surface of the connecting column 2010 through the guide horizontal groove 2012. The movement of the transmission horizontal plate 209 pushes the connecting column 2010 to move. The connecting column 2010 drives the transmission vertical plate 207 to rotate around the support rotating column 204. The rotation of the transmission vertical plate 207 drives the vibration value pointer 205 to rotate. At this time, the vibration value pointer 205 rotates on the surface of the vibration value dial 206. The vibration value dial 206 has a scale with a value, which can display the vibration value of the drive motor body 401. Then, it can be determined whether the vibration amplitude of the drive motor body 401 is too large, so as to understand whether the drive motor body 401 is missing a phase.

[0043] Example 2

[0044] Please see Figure 1 , 2 3 and 4 represent the second embodiment of the present invention, which is based on the previous embodiment.

[0045] A testing mechanism 3 is fixedly connected to the left side of the top of the testing platform 101. The testing mechanism 3 includes a testing bracket 301. The bottom of the testing bracket 301 is fixedly connected to the top of the testing platform 101. A multimeter 302 is installed on the top of the inner cavity of the testing bracket 301. A data display screen 307 is fixedly connected to the top right side of the multimeter 302. A control button 303 is fixedly connected to the bottom right side of the multimeter 302. Connectors 306 are fixedly connected to the front and back sides of the bottom right side of the multimeter 302. A transmission line 305 for transmitting voltage values ​​is fixedly connected to the right side of the connector 306. A clamp 304 for detecting the voltage of the drive motor body 401 is fixedly connected to one end of the transmission line 305.

[0046] Limiting slots 308 are provided on the front and back sides of the inner cavity of the test bracket 301. The two ends of the limiting slots 308 are set with a beveled structure. Limiting strips 309 that are inserted into the limiting slots 308 are fixedly connected to the front and back sides of the multimeter 302. Through the setting of the limiting slots 308, the limiting strips 309 can be smoothly inserted into the interior of the test bracket 301, thereby fixing the position of the multimeter 302 and further facilitating the installation and removal of the multimeter 302.

[0047] The specific implementation method of this embodiment is as follows: the multimeter 302 drives the limiting insert 309 to move downward, and the limiting insert 309 is inserted into the interior of the test bracket 301 from top to bottom until the multimeter 302 is installed inside the test bracket 301. Then, the fixing clip 304 is clamped on the surface of the terminal 406 to detect the voltage of the drive motor body 401. The voltage is transmitted to the interior of the data display screen 307, and the voltage data of the drive motor body 401 is displayed on the data display screen 307.

[0048] Example 3

[0049] Please see Figure 1 , 4 5, 8 and 9, are the third embodiments of the present invention, which are based on the previous embodiment.

[0050] A new energy drive motor body 4 is installed on the top left side of the fixed mechanism 5. The new energy drive motor body 4 includes a drive motor body 401 and a vibration transmission seat 405. An output shaft 402 is fixedly connected to the output end of the drive motor body 401. A junction box 407 is fixedly connected to the left side of the drive motor body 401. Terminal posts 406 are fixedly connected to both sides of the top of the junction box 407. A base 403 for supporting the drive motor body 401 is fixedly connected to the bottom of the drive motor body 401. Connecting bolts 404 for fixing the base 403 are threaded to the four corners of the inner cavity of the base 403. The bottom of the base 403 is connected to the top of the transmission push rod 503 through the connecting bolts 404.

[0051] The specific implementation method of this embodiment is as follows: the base 403 is attached to the top of the transmission rod 503 by the drive motor body 401, and then the base 403 and the transmission rod 503 are connected and fixed by the connecting bolt 404. In this way, the drive motor body 401 can be fixed to the top of the transmission rod 503, which facilitates the detection of the phase loss of the drive motor body 401.

[0052] Example 4

[0053] Please see Figure 1 , 45. The fourth embodiment of the present invention is based on the previous embodiment.

[0054] A fixing mechanism 5 is fixedly connected to the right side of the top of the testing platform 101. The fixing mechanism 5 includes a fixed base 501 and a transmission push rod 503. A groove 502 is provided in the inner cavity of the fixed base 501. A support base plate 504 is movably connected to the bottom of the inner cavity of the groove 502. The top of the support base plate 504 is fixedly connected to the bottom of the transmission push rod 503.

[0055] The support base plate 504 has a first magnet 505 fixedly connected to both sides of the top and both sides of the bottom. The inner wall of the groove 502 has a second magnet 506 with the same magnetism as the second magnet 506 fixedly connected to both sides of the bottom and both sides of the top. By setting the first magnet 505 and the second magnet 506, the support base plate 504 can be made to shake inside the groove 502 by using the principle that like poles of magnets repel and unlike poles attract, thereby improving the stability of the drive motor body 401 when it vibrates.

[0056] Guide grooves 507 are provided on both sides of the inner wall of the fixed base 501. Support springs 508 are fixedly connected to the top and bottom of the inner wall of the guide grooves 507. Guide slides 509 are fixedly connected to the inner side of the support springs 508. The surface of the guide slides 509 is movably connected to the inside of the guide grooves 507. The inner side of the guide slides 509 is fixedly connected to the outer side of the transmission push rod 503. Through the setting of the guide grooves 507, the guide slides 509 can slide smoothly inside the fixed base 501. The sliding of the guide slides 509 can cause the support springs 508 to compress and deform, thereby absorbing the vibration force of the transmission push rod 503.

[0057] The specific implementation of this embodiment is as follows: the force is transmitted to the base 403 by the shaking of the drive motor body 401, and the transmission rod 503 shakes through the base 403. The transmission rod 503 shakes inside the groove 502. The shaking of the transmission rod 503 drives the first magnet 505 to shake between the second magnet 506. At the same time, the shaking of the transmission rod 503 can drive the guide slide 509 to move. The movement of the guide slide 509 causes the support spring 508 to compress and deform.

[0058] Example 5

[0059] Please see Figure 1-9The specific implementation method of this embodiment is as follows: First, the drive motor body 401 drives the base 403 to attach to the top of the transmission push rod 503. Then, the base 403 and the transmission push rod 503 are connected and fixed by the connecting bolt 404. This fixes the drive motor body 401 to the top of the transmission push rod 503, which facilitates the detection of phase loss in the drive motor body 401. Then, the multimeter 302 drives the limit insert 309 to move downward, and the limit insert 309 is inserted into the interior of the test bracket 301 from top to bottom until the multimeter 302 is installed inside the test bracket 301. The fixing clip 304 is then clamped onto the surface of the terminal block 406 to detect the voltage of the drive motor body 401. The voltage is transmitted to the data display screen 307, which displays the voltage data of the drive motor body 401. Simultaneously, the clamping detection seat 203 is clamped onto the surface of the vibration transmission seat 405. The vibration of the drive motor body 401 causes the clamping detection seat 203 to move, rotating around the supporting movable shaft 202. This rotation of the supporting movable shaft 202 drives the transmission cross plate 209 to rotate, and the transmission cross plate 209 rotates via the guide cross plate. The groove 2012 slides on the surface of the connecting column 2010. The movement of the transmission horizontal plate 209 pushes the connecting column 2010 to move, and the connecting column 2010 drives the transmission vertical plate 207 to rotate around the supporting rotating column 204. The rotation of the transmission vertical plate 207 drives the vibration value pointer 205 to rotate. At this time, the vibration value pointer 205 rotates on the surface of the vibration value dial 206, and the surface of the vibration value dial 206 has a scale to display the vibration value of the drive motor body 401. This allows for the determination of whether the vibration amplitude of the drive motor body 401 is too large, thereby understanding the vibration value of the drive motor body 401. 1. Whether there is a phase loss, the force is finally transmitted to the base 403 by the shaking of the drive motor body 401. The base 403 causes the transmission push rod 503 to shake, and the transmission push rod 503 shakes inside the groove 502. The shaking of the transmission push rod 503 drives the first magnet 505 to shake between the second magnet 506. At the same time, the shaking of the transmission push rod 503 can drive the guide slide 509 to move. The movement of the guide slide 509 causes the support spring 508 to be compressed and deformed (the above is the working process of the whole device.
