Description

Technical Field

[0001] The present invention belongs to the technical field of new energy vehicle converter detection. Specifically, it relates to a detection device for new energy vehicle converters. Background Art

[0002] There are very big differences in the assemblies involved in the maintenance processes of new energy vehicles and traditional vehicles. During major overhaul-level maintenance and repair of new energy vehicles after a relatively long service time (5 - 8 years), important assembly components such as power batteries and converters need to be disassembled from the vehicle for component testing, repair, etc. Existing repair workshops generally use lift tables or small cranes to disassemble and install the converters, and after disassembly, they are generally placed on a general workbench for corresponding testing and repair work.

[0003] According to the requirements of relevant industry standards, after the converter is disassembled, if no obvious deformation or damage is found on its appearance, after checking its basic performance (such as internal resistance, voltage transformation performance, etc.), waterproof testing, air pressure sealing testing, vibration environment testing and other testing contents are also required. The general workbench cannot meet the above testing needs, so that different equipment needs to be replaced when the converter is tested by different methods, which is time-consuming and laborious. Moreover, the testing functions of some testing equipment are not perfect enough, and the testing effects are not ideal enough.

[0004] For example, the publication number CN116430158B discloses a detection device for new energy vehicle converters, belonging to the technical field of converter detection. It includes a support base, on which a detection base is connected through an adjustable support rod. A support column is fixedly connected to the inner bottom of the detection base. A plurality of protective fan-shaped parts are rotatably arranged on the support column. The plurality of protective fan-shaped parts are arranged in a spherical shape. A detection spherical part is arranged inside the plurality of protective fan-shaped parts. A sealing end cover is threadedly connected to the detection spherical part. A leakage induction component is arranged on the sealing end cover. A rectangular opening is formed on the detection spherical part. A wiring terminal seat is movably arranged in the rectangular opening. The wiring terminal seat is connected to an aviation plug connected to the vehicle converter through a control connection component. The present invention can independently realize the differential testing of the installation direction and angle of the vehicle converter, simulated vehicle vibration testing, and waterproof and soaking testing, and multiple detection methods can also be detected simultaneously, so as to ensure the accuracy and comprehensiveness of the detection results.

[0005] Existing detection equipment can only detect the jitter and waterproofness of the converter, making it difficult to confirm the working performance of the converter under different air pressures, affecting the working conditions of new energy vehicle converters at different altitudes, and it is also not convenient to conduct tests in sandy and gravel fields.

[0006] To solve the above problems, a detection device for new energy vehicle converters is proposed in this application. Summary of the Invention

[0014] The pressure regulating mechanism comprises an air pumping plate and an air compression plate, wherein the air pumping plate and the air compression plate are slidably mounted on the inner wall of the inflation box and cooperate with the fixed pipe.

[0015] Preferably, the sealing mechanism further comprises two isolation boxes, the two isolation boxes are fixedly mounted on the top of the cover plate, and the two isolation boxes are rotatably connected with a same driving rod, which is fixedly connected to the output shaft of the first motor.

[0016] The two isolation boxes are connected to the driving rod through rotation, so that the driving rod can be positioned, and the driving rod can be driven to rotate through the output shaft of the first motor.

[0017] Preferably, two worms are fixedly mounted on the driving rod, a worm wheel is fixedly mounted on the top end of the lifting rod, and the worm and the corresponding two worm wheels are meshed with each other.

A slider is fixedly installed on the inner wall of the activity hole, and a cam groove is formed in the roller, and the cam groove is slidably connected with the slider.

[0032] The rotating fixed shaft drives the roller to rotate. The roller drives the connecting plate to move back and forth through the sliding connection between the cam groove and the slider. The connecting plate drives the knocking rod to knock and vibrate the placement seat back and forth, so as to perform vibration operation detection on the new energy vehicle converter.

[0033] To sum up, the technical effects and advantages of the present invention:

[0034] Through the rotational connection of the hinge rod with the moving block and the fixed block, and the mutual cooperation of the ejector rod and the cover plate, when the cover plate seals and covers the placement groove, it can automatically drive the clamping plate to clamp and fix the new energy vehicle converter, which is convenient for detection.

[0035] Since the two through holes on the two adjusting plates are arranged in a staggered manner, when the rotating adjusting plate drives the through hole to communicate with the corresponding guide hole, the through hole and the guide hole on the other adjusting plate form a closed state, thereby maintaining the one-way sealing operation of the air extraction plate and the air compression plate, and then facilitating the air extraction and inflation of the placement groove and adjusting the air pressure for detection.

[0060] Refer to Figure 7, a second motor 14 is fixedly installed on the right support plate 2 of the two support plates 2. Transmission gears 15 are fixedly installed on the output shaft of the second motor 14 and on the fixed shaft 13 respectively. The two transmission gears 15 are meshed with each other.

[0061] Refer to Figure 7 , a knocking rod 18 is slidably connected to the right support plate 2 of the two support plates 2. One end of the knocking rod 18 is fixedly installed with a connecting plate 17. One end of the fixed shaft 13 is fixedly installed with a roller 16. An activity hole 19 is formed in the connecting plate 17. The activity hole 19 is movably connected to the roller 16. A slider 21 is fixedly installed on the inner wall of the activity hole 19. A cam groove 20 is formed in the roller 16. The cam groove 20 is slidably connected to the slider 21. The rotating fixed shaft 13 drives the roller 16 to rotate.

The connecting plate 17 drives the knocking rod 18 to knock and vibrate the placement seat 1 back and forth, so as to perform vibration operation detection on the new energy vehicle converter.

[0062] Working principle: During operation, place the vehicle converter in the placement groove 4, start the switch of the first motor 52, the output shaft of the first motor 52 drives the driving rod 54 to rotate. The rotating driving rod 54 drives the lifting rod 51 to rotate through the meshing of the worm 55 and the worm gear 56. The lifting rod 51 is threadedly connected to the placement seat 1, so it can move up and down, and then drives the cover plate 8 to cover and seal the placement groove 4. The ejector rod 67 moves downward under the pressing action of the cover plate 8. The ejector rod 67 drives the moving block 62 to move. The moving block 62 drives the clamping plate 61 to change its lateral position through the hinge rod 63. Thus, the vehicle converter can be clamped and fixed by the two clamping plates 61. The sliding rod 65 is slidably connected to the positioning block 64, so it can limit the movement of the moving block 62, making the moving block 62 move stably, and under the action of the return spring 66, it can drive the moving block 62 to reset, thus driving the clamping plate 61 to release the fixing effect on the vehicle converter. When it is necessary to reduce the air pressure in the placement groove 4, misalign the guide hole 74 on the air extraction plate 71 with the through hole 76 on the adjusting plate 75, while the guide hole 74 on the air pressure plate 72 is in communication with the through hole 76 on the adjusting plate 75. This makes the air extraction plate 71 move downward under the action of the counterweight 77 and the pull rod 73, creating a negative pressure state between the inflation tank 11 and the placement groove 4. Then, the converter can be detected under the negative pressure state. When it is necessary to detect under a high air pressure state, align the guide hole 74 on the air extraction plate 71 with the through hole 76 on the adjusting plate 75, while misalign the guide hole 74 on the air pressure plate 72 with the through hole 76 on the adjusting plate 75. This makes the air pressure plate 72 move downward under the action of the counterweight 77 and the pull rod 73. Thus, the air pressure plate 72 can squeeze the inflation tank 11 and the placement groove 4, so as to detect the converter under a high air pressure state. At the same time, during the detection, start the switch of the second motor 14. The output shaft of the second motor 14 drives the fixed shaft 13 to rotate through the meshing of the two transmission gears 15. The fixed shaft 13 drives the placement seat 1 to rotate, so as to rotate and detect the new energy vehicle converter in the placement groove 4. The rotating fixed shaft 13 drives the roller 16 to rotate. The roller 16 drives the connecting plate 17 to move back and forth through the sliding connection of the cam groove 20 and the slider 21. The connecting plate 17 drives the knocking rod 18 to knock and vibrate the placement seat 1 back and forth, so as to perform vibration operation detection on the new energy vehicle converter. Through the setting of the stuffing box 9, the sand in the stuffing box 9 shakes, and then the performance of the converter under the condition of sand is detected. The setting of the switch 10 can control the introduction of the sand in the stuffing box 9.

[0063] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
