[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0029] The embodiments of this utility model will be described below based on its overall structure.
[0030] A testing device for the end-of-life (EOL) function of a new energy vehicle motor controller, such as Figures 1-4 As shown, the system includes a base 1, with support legs connected to the four corners of the bottom of the base 1. A control panel is connected to the center of one side of the base 1, with several operation buttons connected to the bottom of one side of the control panel and a display screen connected to the center of the top of one side of the control panel. A protective frame 2 is connected to the top of one side of the base 1, with an alarm light connected to the center of the top of one side of the protective frame 2. A safety door 3 is provided on the top of one side of the protective frame 2, and a support base 13 is provided on one side of the inner cavity of the protective frame 2. The bottom of the support base 13 is connected to the top of one side of the base 1. An adjustment component 4 is provided on one side of the support base 13. The adjustment component 4 includes two fixing ears 41 located on one side of the support base 13, and one side of each fixing ear 41 is connected to the top of one side of the protective frame 2.
[0031] When staff use this testing device to perform EOL (End-of-Life) function testing on a new energy vehicle motor controller, they first connect the device to an external power supply. Then, they place the new energy vehicle motor controller to be tested into the placement slot on the placement platform 6. Next, they insert the new energy vehicle motor controller connector into the electrical connector 9, and then connect the two water-cooling connectors 8 to the new energy vehicle motor controller. Then, they operate the control panel buttons to power the drive motor 12, which quickly moves the new energy vehicle motor controller on the placement platform 6 towards the bottom of several high-voltage contact terminals 15. Once the new energy vehicle motor controller on the placement platform 6 has moved to the bottom of the several high-voltage contact terminals 15, the staff then operates the control panel buttons to power the adjusting motor 42 and the electric telescopic rod 18, thereby enabling... The safety gate 3 moves downward to close the protective frame 2 for testing. Simultaneously, the electric telescopic rod 18, when energized, moves several high-voltage contact terminals 15 downward to connect with the new energy vehicle motor controller placed on the platform 6, allowing for testing. The test results are displayed on the control panel screen for recording. After testing, the operator uses the control panel buttons to power the adjusting motor 42, the electric telescopic rod 18, and the drive motor 12, causing the safety gate 3 to rise, the high-voltage contact terminals 15 to move upward to connect with the new energy vehicle motor controller, and the platform 6 to move the new energy vehicle motor controller forward. Then, the operator disconnects the electrical connector 9 and the two water-cooling connectors 8 from the new energy vehicle motor controller, allowing the new energy vehicle motor controller to be removed from the testing device.
[0032] like Figure 1 , Figure 2 and Figure 4As shown, the support base 13 has connecting ears 5 near the four corners of its top. The two connecting ears 5 on one side are connected to a threaded rod 11 at the center of one side. One end of the threaded rod 11 is equipped with a drive motor 12. The drive motor 12 is connected to the center of the top of the adjacent connecting ear 5. A rotating hole is opened in the center of the inner cavity of the connecting ear 5 on one side. One end of the drive motor 12's power output shaft passes through the rotating hole and is connected to the center of one end of the threaded rod 11. A placement platform 6 is fitted on one end of the threaded rod 11. A placement groove is opened in the center of the top of the placement platform 6. A drive hole is opened in the center of one side of the inner cavity of the placement platform 6. The inner wall of the drive hole is provided with an internal thread that matches the threaded rod 11. A support frame 7 is connected to the center of one side of the top of the placement platform 6. An electrical connector 9 is connected to one side of the top of the support frame 7. Two water-cooling connectors 8 are connected to the top of one side of the support frame 7.
[0033] When the operator inserts the connector of the new energy vehicle motor controller placed on the placement platform 6 into the electrical connector 9, and connects the two water-cooled connectors 8 to the new energy vehicle motor controller, the operator then operates the control panel to supply power to the drive motor 12. The drive motor 12, when energized, drives the threaded rod 11 to rotate forward. When the threaded rod 11 rotates forward, it moves the new energy vehicle motor controller placed on the placement platform 6 towards the bottom of several high-voltage contact terminals 15. Once the new energy vehicle motor controller on the placement platform 6 has moved to the bottom of the several high-voltage contact terminals 15, the operator then operates the control panel... The control panel buttons power the adjusting motor 42 and the electric telescopic rod 18, which in turn moves the safety gate 3 downward to close the protective frame 2 for testing. When powered on, the electric telescopic rod 18 extends downward, which in turn moves the fixing frame 17 downward. When the fixing frame 17 moves downward, it moves the guide plate 21 downward on the two pillars 14, which in turn allows the guide plate 21 to smoothly move several high-voltage contact terminals 15 downward to connect with the new energy vehicle motor controller placed on the placement platform 6 for testing. This improves the automatic performance of the testing device to a certain extent.
[0034] like Figure 4As shown, the threaded rod 11 has two support pillars 14 at one end. The bottom ends of the two support pillars 14 are connected to one side of the top of the base 1, and the top ends of the two support pillars 14 are connected to a top plate 19. A guide plate 21 is fitted on the two support pillars 14 near the top. A fixing frame 17 is connected to the center of the top of the guide plate 21. A copper busbar 20 is connected to the inner wall of the top of the fixing frame 17. Several connecting wires 16 are connected to the center of the bottom of the copper busbar 20, and the spacing between two adjacent connecting wires 16 is the same. The bottom ends of the several connecting wires 16 are connected to high-voltage contact terminals 15, and one side of the top of the several high-voltage contact terminals 15 is connected to the center of the top of the guide plate 21. An electric telescopic rod 18 is provided on the top of the fixing frame 17, and the bottom of the electric telescopic rod 18 is connected to the center of the top of the top of the top plate 19. A through hole is opened in the center of the inner cavity of the top plate 19, and the bottom end of the electric telescopic rod 18 is connected to the center of the top of the fixing frame 17.
[0035] When the staff operates the control buttons on the control panel to supply power to the electric telescopic pole 18, the electric telescopic pole 18 can move downward through the fixing frame 17 to connect with the new energy vehicle motor controller placed on the placement platform 6, and then the test can be carried out.
[0036] like Figure 1 , Figure 2 and Figure 4 As shown, a guide hole is provided at the center of the other side of the inner cavity of the placement platform 6, and a guide rod 10 is movably connected to the inner cavity of the guide hole. Both ends of the guide rod 10 penetrate the inner cavity of the guide hole, and both ends of the guide rod 10 are respectively connected to the center of one side of the adjacent connecting ear 5.
[0037] When the placement platform 6 moves backward or forward, it can slide on the guide rod 10, thereby limiting the position of the placement platform 6 and enabling the placement platform 6 to move smoothly backward or forward.
[0038] like Figure 1 and Figure 3 As shown, an adjusting screw 45 is movably connected to the center of one side of the two fixed ears 41, and an adjusting plate 43 is sleeved on the adjusting screw 45 near the top. A round hole is opened at the center of one side of the inner cavity of the adjusting plate 43, and the inner wall of the round hole is provided with an internal thread that matches the adjusting screw 45. A connecting bracket 44 is connected to the center of one side of the adjusting plate 43, and one side of the connecting bracket 44 is connected to the center of the top of one side of the safety door 3.
[0039] When the operator operates the control panel to supply power to the regulating motor 42, the regulating motor 42 can drive the regulating screw 45 to rotate in the forward or reverse direction. When the regulating screw 45 rotates in the forward or reverse direction, it can drive the regulating plate 43 to move downward or upward. When the regulating plate 43 moves downward or upward, it can drive the safety door 3 to move downward or upward through the connecting bracket 44. This achieves the purpose of conveniently closing or opening the safety door 3, so that the operator can conveniently close the safety door 3 to perform EOL function testing on the new energy vehicle motor controller, or open the safety door 3 to remove the tested new energy vehicle motor controller from the device, thus facilitating actual use.
[0040] like Figure 1 and Figure 3 As shown, an adjustment motor 42 is provided on the top of the fixed ear 41 located at the top, and the bottom of the adjustment motor 42 is connected to the center of one side of the top of the adjacent fixed ear 41. A movable hole is provided at the center of one side of the inner cavity of the fixed ear 41 located at the top. The bottom end of the power output shaft of the adjustment motor 42 passes through the inner cavity of the movable hole and is connected to the center of the top of the adjustment screw 45.
[0041] When the operator controls the operation buttons on the control panel to supply power to the regulating motor 42, the regulating motor 42 can quickly drive the regulating screw 45 to rotate in the forward or reverse direction when it is powered on.
[0042] like Figure 1 and Figure 3 As shown, a limiting hole is provided at the center of the other side of the inner cavity of the adjusting plate 43, and a limiting rod 46 is movably connected to the inner cavity of the limiting hole. Both the upper and lower ends of the limiting rod 46 pass through the inner cavity of the limiting hole, and the upper and lower ends of the limiting rod 46 are respectively connected to the center of the other side of the fixing ear 41.
[0043] When the adjusting plate 43 moves downward or upward, it can slide on the limiting rod 46, thereby limiting the position of the adjusting plate 43 and enabling the adjusting plate 43 to move smoothly.
