Description

Technical Field

[0001] This invention relates to the technical field of high-voltage electrical testing for new energy vehicles, specifically to a non-contact automated high-voltage electrical testing platform for new energy vehicles. Background Technology

[0002] In the final stage of the production and manufacturing of new energy vehicles, the entire vehicle needs to undergo quality inspection. Among the most important aspects is the high-voltage electrical testing of the new energy battery pack. This process can reflect the stability between various systems within the new energy vehicle, and therefore requires the use of a new energy vehicle high-voltage electrical testing device.

[0003] There are many types of existing high-voltage electrical testing devices. However, for example, they have limitations in testing the high-voltage electrical condition of new energy vehicles, and cannot effectively guarantee reliability and safety. To solve these problems, one can refer to the prior art (Chinese patent application number CN202510205732.2, application date 2025-02-25) which discloses a device and method for detecting the high-voltage electrical condition of new energy vehicles. This device tests the stability and installability of the high-voltage electrical condition of the vehicle motor. The vibration detection mechanism, which is mainly set up, can combine three sets of pressure change data to perform three-dimensional simulation amplification of the micro-vibration of the vehicle motor, so as to realize the detection of the safety and reliability of the vehicle motor. Moreover, the load adjustment component can assist in the test adjustment and expand the test range. Another reference is the prior art (Chinese patent application number CN202510037813.6, application date 2025-01-10) which discloses a portable tester for new energy vehicle motors. This tester has a highly integrated design and can be carried for use in multiple scenarios. It can conveniently test the electrical condition of new energy vehicles. The machine is run idle to check the operating status and performance data of the motor under test. It also has the functions of adjusting the angle of the rotary transformer of the motor under test and testing the protection level of the motor. Finally, referring to the prior art (Chinese patent application number CN202411903731.7, application date 2024-12-23), an automatic testing device for automotive capacitor electrical parameters is disclosed. It is convenient to transport the capacitors to be tested in batches to the testing area on the frame, improve the inspection efficiency, and avoid the problems of detection errors or missed detections caused by manual inspection of capacitors. The frame is equipped with a drive mechanism to drive two detection contact mechanisms to reciprocate, so that the two detection contact mechanisms contact the electrodes of the same capacitor respectively for a period of time, thereby measuring different parameters and improving the detection efficiency. The frame is equipped with a guide mechanism to guide the capacitor to move along the transmission direction of the transmission mechanism, so as to avoid the problem of the detection end of the detection contact mechanism failing to contact the capacitor electrode or the problem of incomplete contact when the capacitor moves along the transmission direction under the transmission mechanism, which would lead to the problem of the detection end of the detection contact mechanism failing to contact the capacitor electrode or the problem of inaccurate detection results of the capacitor under test.

[0004] While the aforementioned devices can improve the reliability of testing, they still have certain shortcomings when testing batteries in new energy vehicles. New energy vehicles are composed of multiple battery packs, and the position of the testing device needs to be adjusted during testing. This requires staff to move back and forth, resulting in low overall testing efficiency and hindering rapid subsequent testing and processing.

[0005] Therefore, we propose a non-contact automated high-voltage electrical testing platform for new energy vehicles to address the problems mentioned above. Summary of the Invention

The front wheel limiting mechanism and the rear wheel limiting mechanism act on the outer side of the new energy vehicle wheel to prevent shaking during the test. The rear wheel limiting mechanism includes a flipping mechanism and an inclined block. The inclined block is rotatably set at the right end of the support frame. The actuator of the flipping mechanism acts on the outer side of the inclined block, and the rear wheel of the car is limited by the flipping of the inclined block.

[0008] Preferably, a roller body is fixed at the bottom of the support frame, and a battery test port is opened through the center of the surface of the support frame. The size of the battery test port is larger than the maximum cross-sectional size of the battery box of the new energy vehicle to be tested, and the roller body and the outer side of the capacitor coupling test piece are staggered.

[0009] Preferably, the adjustment mechanism includes a threaded rod fixed at the output end of the drive motor, the outer side of the threaded rod being threadedly connected to the bottom end of the support frame, the other side of the support frame being fixed to a guide rod, and the other end of the guide rod being fixed to the side wall of the fixed base.

[0010] Preferably, the flipping mechanism includes a mating roller that contacts the front bumper of the vehicle. The shaft end of the mating roller is rotatably disposed on the inner side of the horizontal plate. A piston rod is fixed on the outer side of the horizontal plate. The outer end of the piston rod is slidably disposed inside a fixed cylinder. The fixed cylinder is fixed inside a support frame and is filled with hydraulic oil. The outer end of the fixed cylinder is connected to a receiving tube via a connecting hose. A drive rod is slidably disposed inside the receiving tube. A movable rack is fixed on the outer end of the drive rod. The outer end of the movable rack is meshed with the outer side of a transmission gear. The shaft end of the transmission gear is fixedly connected to the inclined block.

[0011] Preferably, the material of the mating roller is rubber, the horizontal plate is L-shaped, and the rotation range of the inclined block is 0° to 90°.

[0012] Preferably, a rubber ring is nested on the outer side of the piston rod, and the outer side of the rubber ring is attached to the inner wall of the fixed cylinder. The outer end of the piston rod is connected to the fixed cylinder through a return spring.

[0013] Preferably, the flipping mechanism is symmetrically distributed in two sets about the transverse centerline of the support frame, and the top of the receiving tube is fixed at the bottom edge of the support frame.

[0014] Preferably, the front wheel limiting mechanism includes transverse grooves opened on the front and rear sides of the support frame. A rotating gear is rotatably arranged inside the transverse groove. A threaded tube is fixed at the center of the rotating gear. The bottom of the threaded tube is rotatably arranged inside the support frame. A connecting sleeve is threadedly connected to the top of the threaded tube. The top of the connecting sleeve is fixed to the bottom of the lifting frame.

[0015] Preferably, the outer side of the rotating gear is on the same horizontal line as the fixed rack fixed to the inner wall of the fixed base, and the lifting frame is slidably disposed on the top surface of the support frame. An anti-slip pad is adhered to the top of the support frame, and connecting sleeves are fixed at both the front and rear ends of the lifting frame.

[0016] Preferably, the control panel is electrically connected to the capacitive coupling test piece and the drive motor.

[0017] Compared with existing technologies, the advantages of this invention are as follows: This non-contact automated high-voltage electrical testing platform for new energy vehicles features a drive motor and adjustment mechanism linked on the fixed base, which can automatically adjust the position of the support frame. It can adapt to the testing needs of multiple battery boxes without manual intervention, significantly reducing manual operation steps during the testing process and greatly improving testing efficiency. The capacitive coupling test piece adopts a non-contact testing method, coupled with the battery test port in the center of the support frame, ensuring the safety of high-voltage electrical testing while avoiding wear on the battery box caused by contact testing. The front wheel limiting mechanism and the rear wheel limiting mechanism form a bidirectional fixation, the tilting mechanism drives the inclined block to tilt via hydraulic transmission, and the lifting frame achieves height adjustment through gear meshing. This dual limiting structure effectively prevents vehicle shaking during testing, ensuring the accuracy of test data. Specific details are as follows: 1. By adjusting the threaded rod and guide rod in the mechanism, the support frame is driven to slide smoothly, ensuring accurate alignment of the battery box and the capacitor coupling test piece, avoiding positioning deviations caused by manual adjustment, and improving test accuracy; the rollers of the rear wheel limiting mechanism are made of rubber and make flexible contact with the car bumper, which not only ensures the limiting effect but also prevents scratch damage to the car body. The reset spring allows the rollers to automatically rebound and reset, adapting to the testing needs of different car models; Furthermore, the symmetrical distribution of the tilting mechanism and the front wheel limiting mechanism ensures that the vehicle is subjected to uniform force, further enhancing the stability during the test process. This effectively avoids test interruptions or data errors caused by vehicle body shaking, making it suitable for high-voltage electrical testing of various models of new energy vehicles and broadening the applicability of the device.

[0018] 2. The staggered distribution of rollers and capacitively coupled test pieces at the bottom of the support frame ensures smooth sliding of the support frame while avoiding interference between components, thus extending the service life of the device. The rubber ring on the outside of the piston rod enhances the sealing of the fixed cylinder, ensuring the stability of the hydraulic transmission and enabling the tilting mechanism to respond quickly and accurately. The anti-slip pad on the top of the support frame further improves the stability of the vehicle and reduces the risk of slippage. The centralized electrical connection design of the control panel allows operators to quickly start and stop the equipment, adjust the position, and control the test, lowering the operating threshold.

[0021] 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.

[0022] Please see Figures 1-9 The present invention provides the following technical solution: a non-contact automated high-voltage electrical testing platform for new energy vehicles.

[0023] Example 1: To address the issue that current new energy vehicles on the market consist of multiple battery packs, requiring adjustments to the testing equipment during testing, necessitating personnel to move back and forth, resulting in slow overall testing efficiency and hindering subsequent rapid testing and processing, please refer to the attached... Figure 1 -Appendix Figure 8A drive motor 4 is installed on one side of the fixed base 1. The output end of the drive motor 4 is connected to the adjustment mechanism, which is used to adjust the position of the support frame 6. A front wheel limiting mechanism and a rear wheel limiting mechanism are respectively set on the left and right sides of the support frame 6. The front wheel limiting mechanism and the rear wheel limiting mechanism act on the outside of the new energy vehicle wheels to prevent shaking during the test. The rear wheel limiting mechanism includes a flipping mechanism and an inclined block 9. The inclined block 9 is rotatably set at the right end of the support frame 6. The execution end of the flipping mechanism acts on the outside of the inclined block 9, and the rear wheel of the car is limited by the flipping of the inclined block 9. The adjustment mechanism includes a threaded rod 5 fixed at the output end of the drive motor 4. The outer side of the threaded rod 5 is threadedly connected to the bottom end of the support frame 6. The other side of the support frame 6 is fixed to the guide rod 8. The other end of the guide rod 8 is fixed to the side wall of the fixed base 1. The flipping mechanism includes a mating roller 10 that contacts the front bumper of the car. The shaft end of the mating roller 10 is rotatably set on the inner side of the horizontal plate 11. A piston rod 12 is fixed to the outer side of the 11. The outer end of the piston rod 12 is slidably disposed inside the fixed cylinder 13. The fixed cylinder 13 is fixed inside the support frame 6 and is filled with hydraulic oil. The outer end of the fixed cylinder 13 is connected to the receiving tube 15 through a connecting hose 14. A drive rod 16 is slidably disposed inside the receiving tube 15. A movable rack 17 is fixed to the outer end of the drive rod 16. The outer end of the movable rack 17 is meshed with the outer side of the transmission gear 18. The shaft end is fixedly connected to the inclined block 9; the roller 10 is made of rubber, and the horizontal plate 11 is L-shaped. The rotation range of the inclined block 9 is 0° to 90°; a rubber ring is nested on the outer side of the piston rod 12, and the outer side of the rubber ring is attached to the inner wall of the fixed cylinder 13. The outer end of the piston rod 12 is connected to the fixed cylinder 13 through the return spring 121; there are two sets of flipping mechanisms symmetrically distributed about the transverse center line of the support frame 6, and the top of the receiving tube 15 is fixed to the bottom edge of the support frame 6.

[0024] Before testing, the new energy vehicle is driven to the top surface of the support frame 6, and the front bumper of the vehicle contacts and applies pressure to the mating roller 10 of the tilting mechanism. Since the mating roller 10 is made of rubber and the horizontal plate 11 is L-shaped, the pressure will push the horizontal plate 11 to drive the piston rod 12 to slide into the fixed cylinder 13. The rubber ring on the outside of the piston rod 12 ensures the sealing during the sliding process, while compressing the return spring 121. The hydraulic oil filled inside the fixed cylinder 13 flows to the receiving tube 15 through the connecting hose 14 under the pressure of the piston rod 12, pushing the drive rod 16 inside the receiving tube 15 to slide outward. The drive rod 16 drives the movable rack 17 fixed at the outer end to move synchronously. The movable rack 17 meshes with the transmission gear 18, thereby driving the inclined block 9 fixed at the shaft end of the transmission gear 18 to tilt. When the inclined block 9 tilts along the rotation axis to a 90° angle with the top surface of the support frame 6, it just presses against the rear of the vehicle. Outside the wheel, the rear wheel is limited; two sets of symmetrically distributed flipping mechanisms ensure that the force on both sides of the car is balanced, avoiding unilateral deviation; after starting the test, the drive motor 4 is started through the control panel 2, and the output end of the drive motor 4 drives the threaded rod 5 to rotate. Since the threaded rod 5 is threadedly connected to the bottom end of the support frame 6, and the other side of the support frame 6 is fixed to the side wall of the fixed base 1 through the guide rod 8, the rotation of the threaded rod 5 is converted into the smooth sliding of the support frame 6 along the guide rod 8, realizing the automatic adjustment of the test position without manual intervention; after the test, the car drives away from the support frame 6, the pressure of the front bumper on the mating roller 10 disappears, the return spring 121 elastically resets, pulls the piston rod 12 to return to the initial position, the hydraulic oil flows back to the fixed cylinder 13, the drive rod 16 and the moving rack 17 reset synchronously, and the transmission gear 18 drives the inclined block 9 to flip to the 0° initial state, preparing for the next test.

[0025] Example 2: This example differs from Example 1 in that it discloses a structure for limiting the front wheels of a car, facilitating more stable adjustment and testing in later stages. Please refer to the appendix for details. Figure 1 -Appendix Figure 3 and attached Figure 9 The front wheel limiting mechanism includes transverse grooves 19 on both the front and rear sides of the support frame 6. A rotating gear 21 is rotatably installed inside the transverse grooves 19. A threaded tube 22 is fixed at the center of the rotating gear 21. The bottom of the threaded tube 22 is rotatably installed inside the support frame 6. A connecting sleeve 23 is threadedly connected to the top of the threaded tube 22. The top of the connecting sleeve 23 is fixed to the bottom of the lifting frame 24. The outer side of the rotating gear 21 is on the same horizontal line as the fixed rack 20 fixed to the inner wall of the fixed base 1. The lifting frame 24 is slidably installed on the top surface of the support frame 6. An anti-slip pad is adhered to the top of the support frame 6. Connecting sleeves 23 are fixed at both the front and rear ends of the lifting frame 24.

[0026] When the drive motor 4 drives the support frame 6 to slide along the fixed base 1, the rotating gear 21 in the transverse grooves 19 on both the front and rear sides of the support frame 6 moves accordingly. Since the rotating gear 21 and the fixed rack 20 on the inner wall of the fixed base 1 are on the same horizontal line and mesh with each other, the sliding of the support frame 6 drives the rotating gear 21 to rotate around its own center; the threaded tube 22, which is fixed at the center of the rotating gear 21, rotates synchronously. The threaded tube 22 is threadedly connected to the connecting sleeve 23, and the lifting frame 24 is slidably set on the top surface of the support frame 6. The rotation of the threaded tube 22 is converted into the vertical lifting and lowering of the connecting sleeve 23, which in turn drives the lifting frame 24 to move upward along the top surface of the support frame 6; the connecting sleeves 23 are fixed at both the front and rear ends of the lifting frame 24 to ensure that the force is even and stable during the lifting process, until the top surface of the lifting frame 24 presses against the bottom of the front wheel of the car. The anti-slip pad on the top of the support frame 6 increases the friction and realizes the stable limit of the front wheel, preventing the car from sliding back and forth during the test; after the test is completed, the drive motor 4 rotates in the opposite direction, driving the support frame 6 to slide in the opposite direction. The rotating gear 21 meshes with the fixed rack 20 in the opposite direction, the threaded tube 22 rotates in the opposite direction, and the connecting sleeve 23 drives the lifting frame 24 to descend and reset, releasing the limit of the front wheel.

[0027] Example 3: This example mainly discloses a non-contact testing process for automobiles. Please refer to the appendix for details. Figure 1 and attached Figure 2 A control panel 2 is installed on one side of the surface of the fixed base 1, and a capacitive coupling test piece 3 is installed on the inner side of the fixed base 1. A support frame 6 is slidably arranged on the upper inner side of the fixed base 1, and a roller body 61 is fixed at the bottom of the support frame 6. A battery test port 7 is opened through the center of the surface of the support frame 6. The size of the battery test port 7 is larger than the maximum cross-sectional size of the new energy vehicle battery box to be tested, and the roller body 61 and the outer side of the capacitive coupling test piece 3 are staggered. The control panel 2 is electrically connected to the capacitive coupling test piece 3 and the drive motor 4.

[0028] Before testing, it was confirmed that the capacitive coupling test piece 3 was installed inside the fixed base 1, and that the roller body 61 at the bottom of the support frame 6 and the outer side of the capacitive coupling test piece 3 were staggered to avoid interference during sliding and ensure smooth movement of the support frame 6. After the car was parked on the support frame 6, it was fixed by the front and rear wheel limiting mechanisms. The size of the battery test port 7 through the center of the support frame 6 was larger than the maximum cross-sectional size of the battery box to be tested, ensuring that the test range of the capacitive coupling test piece 3 could completely cover the battery box. The operator issued test commands through the control panel 2 on one side of the fixed base 1. Panel 2 is electrically connected to capacitive coupling test piece 3 and drive motor 4, respectively, and commands can be directly transmitted to each component. After drive motor 4 drives the support frame 6 to slide to the target test position, capacitive coupling test piece 3 is activated and performs non-contact high-voltage electrical testing on the automotive battery pack through battery test port 7. Test data can be obtained without direct contact with the battery box, which avoids wear and tear on the battery box caused by contact testing and improves the safety of high-voltage testing. During the test, control panel 2 receives and displays the test data of capacitive coupling test piece 3 in real time, which allows operators to monitor the test status in real time and ensures accurate and efficient testing.

[0029] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
