[0027] The technical solution of this patent will be further described in detail below in combination with the specific implementation mode.

[0028] The embodiments of this patent will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below by referring to the drawings are exemplary and are only used to explain this patent and should not be construed as a limitation of this patent.

[0029] Embodiment 1:

[0030] A battery testing device for new energy vehicle maintenance, as Figures 1 - 6 shown, includes a suspension plate 1 and a detection support 10 fixedly connected with a control component 2 above. The control component 2 has a microprocessor that can process the collected signals and can upload the processed data to the server side. This is currently the prior art. A flipping motor 11 is fixedly connected to the outside of the detection support 10. The power output end of the flipping motor 11 is fixedly connected with a flipping shaft 18. One side of the flipping shaft 18 is fixedly connected with a flipping plate 19. The other end of the flipping shaft 18 is rotatably connected to the inside of the detection support 10. One end of the flipping shaft 18 is movably connected with a probe assembly, and the other end of the flipping shaft 18 is rotatably connected with a cleaning brush roller 24. The cleaning brush roller 24 is made of insulating rubber. One end of the cleaning brush roller 24 is drivingly connected with a cleaning drive component. A scraper 25 and a water storage box 20 are fixedly connected inside the detection support 10;

[0031] The cleaning drive component includes a cleaning motor 21, a synchronous pulley 22 and a synchronous belt 23. The cleaning motor 21 is fixedly connected to one side of the flipping plate 19. Two synchronous pulleys 22 are respectively fixedly connected to one end of the cleaning brush roller 24 and the power output end of the cleaning motor 21. Multiple synchronous pulleys 22 are drivingly connected by the synchronous belt 23;

[0032] When conducting the detection, move the suspension plate 1 downward. Then, the lower end of the cleaning brush 24 can be made to closely adhere to the battery electrode. Subsequently, start the cleaning motor 21 to drive the cleaning brush 24 to perform cleaning through the synchronous pulley 22 and the synchronous belt 23;

[0033] The probe assembly includes a probe bracket 14, a lifting limit rod 15, and a detection probe 17. The lifting limit rod 15 is fixedly connected to both sides of the probe bracket 14. One end of the lifting limit rod 15 is slidably connected to the inner groove of the flip plate 19. The detection probe 17 is fixedly connected below the probe bracket 14. The probe bracket 14 is fixedly connected to the control component 2 through an electric wire

[0034] At the same time, the flip motor 11 drives the flip shaft 18 to rotate. At this time, the cleaning brush 24 at one end of the flip plate 19 can be rotated to fit the scraping plate 25; and through the groove above the flip plate 19, drive the lifting limit rod 15 to move downward, so that the detection probe 17 moves downward to contact the battery electrode, detect and read the battery data, and upload the data to the control component 2 for processing;

[0035] After the cleaning brush 24 contacts the scraping plate 25, the cleaning brush 24 continues to rotate counterclockwise to scrape off the dirt generated during cleaning.

[0036] As Figures 1 - 6 shown, scraping plates 25 are fixedly connected to both sides of the scraping plate 25. The other side of the scraping plate 25 is movably connected to the edge of the cleaning brush 24. A collection port 27 is opened above the dirt collection tank 26;

[0037] The dirt scraped off by the scraping plate 25 will flow along the inclination angle of the scraping plate 25 to both sides and flow into the dirt collection tank 26 through the collection port 27 for centralized recovery.

[0038] As Figures 1 - 6 shown, a water outlet pipe 28 is fixedly connected below the water storage box 20. One end of the water outlet of the water outlet pipe 28 is rotatably connected to a liquid outlet roller 29. The edge of the liquid outlet roller 29 is movably connected to the edge of the cleaning brush 24;

[0039] The water storage box 20 contains cleaning liquid, which can smear the cleaning liquid on the cleaning brush 24 from which the dirt has been scraped off when the cleaning brush 24 drives the liquid outlet roller 29 to roll. Because the amount of smearing is small, it will dry quickly after the cleaning brush 24 cleans the electrode and will not affect the detection of the detection probe 17.

[0040] As Figures 1 - 6 shown, lifting grooves 13 are opened on both sides of the detection bracket 10. The lifting limit rod 15 is slidably connected to the inner side of the lifting groove 13. An anti-deviation plate 16 is fixedly connected to the inner side of the detection bracket 10. The anti-deviation plate 16 is slidably connected to one side of the probe bracket 14;

[0041] The vertical lifting groove 13 and the anti-deviation plate 16 can prevent the detection probe 17 from deflecting when moving downward.

[0042] As Figures 1 - 6 shown, a buffer frame 3 is fixedly connected to the lower part of the suspension plate 1, a stabilizing rod 4 is slidably connected to the lower part of the buffer frame 3, a translation bracket 5 is fixedly connected to the lower part of the stabilizing rod 4, a spring 6 is fixedly connected between the translation bracket 5 and the buffer frame 3, a microswitch 30 is fixedly connected to the lower part of the buffer frame 3, one end of the microswitch 30 is electrically connected to the control component 2. When the suspension plate 1 moves downward, the cleaning brush 24 will contact the electrode, then the spring 6 contracts, triggering the microswitch 30 to start the cleaning motor 21 and the flipping motor 11 for cleaning and detection;

[0043] An air pump 7 is fixedly connected to the upper part of the translation bracket 5, the air outlet end of the air pump 7 is fixedly connected to an inverted Y-shaped cleaning blow pipe 12. When the air pump 7 moves upward, it will trigger the microswitch 30, and the inverted Y-shaped cleaning blow pipe 12 below can blow air on the motor to improve the cleaning effect.

[0044] When this embodiment is in use, during detection, the suspension plate 1 is moved downward. At this time, the lower end of the cleaning brush 24 can be closely attached to the battery electrode, and then the cleaning motor 21 is started to drive the cleaning brush 24 to clean through the synchronous pulley 22 and the synchronous belt 23;

[0045] At the same time, the flipping motor 11 drives the flipping shaft 18 to rotate. At this time, the cleaning brush 24 at one end of the flipping plate 19 can be rotated to fit the scraping plate 25; and through the slot above the flipping plate 19, the lifting limit rod 15 is driven to move downward, so that the detection probe 17 moves downward to contact the battery electrode, detect and read the battery data, and upload the data to the control component 2 for processing;

[0046] After the cleaning brush 24 contacts the scraping plate 25, the cleaning brush 24 continues to rotate counterclockwise to scrape off the dirt generated during cleaning;

[0047] The dirt scraped off by the scraping plate 25 will flow to both sides along the inclination angle of the scraping plate 25 and flow into the sewage collection tank 26 from the collection port 27 for centralized recovery. The water storage box 20 contains cleaning liquid, which can smear the cleaning liquid on the cleaning brush 24 from which the dirt has been scraped off when the cleaning brush 24 drives the liquid outlet roller 29 to roll. Because the smearing amount is small, it will dry quickly after the cleaning brush 24 cleans the electrode and will not affect the detection of the detection probe 17;

[0048] The vertical lifting groove 13 and the anti-deviation plate 16 can prevent the detection probe 17 from deflecting when moving downward. When the suspension plate 1 moves downward, the cleaning brush 24 will contact the electrode. Subsequently, the spring 6 contracts, triggering the microswitch 30 to start the cleaning motor 21 and the flipping motor 11 for cleaning and detection. When the air pump 7 moves upward, it will trigger the microswitch 30, and the inverted Y-shaped cleaning blowpipe 12 below can blow air on the motor to improve the cleaning effect.

[0049] Embodiment 2:

A screw nut 9 is fixedly connected above the detection bracket 10, and a plurality of screw nuts 9 are threadedly connected to both ends of the electric double-headed screw 8. The screw nuts 9 are slidably connected to both sides of the translation bracket 5. The electric double-headed screw 8 can drive the detection brackets 10 on both sides to move and adjust the spacing, so that it can be applied to batteries of different specifications.

[0051] As Figures 1 - 6 shown, a telescopic rod 31 is fixedly connected above the suspension plate 1, a transverse moving slider 32 is fixedly connected above the telescopic rod 31, a transverse moving gantry 33 is movably connected inside the transverse moving slider 32, longitudinal moving sliders 34 are fixedly connected to both ends of the transverse moving gantry 33, a longitudinal moving guide rail 35 is movably connected below the longitudinal moving sliders 34, and a plurality of longitudinal moving guide rails 35 are fixedly connected below to form a detection table 36;

[0052] The telescopic rod 31 is of the electric type and can drive the suspension plate 1 to move up and down. The transverse moving slider 32, the transverse moving gantry 33, the longitudinal moving sliders 34 and the longitudinal moving guide rail 35 can drive the detection bracket 10 to move in multiple directions, which is applicable to a battery pack with multiple batteries.
