Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of battery detection, and in particular to a probe for a new energy vehicle power detection system. BACKGROUND

[0002] New energy vehicles have developed rapidly in recent years as a new direction for the automotive industry. Compared with traditional fuel vehicles, new energy vehicles have the advantages of zero or low emissions, high energy efficiency, and good power performance, and are gradually becoming a popular choice for consumers. However, the detection of new energy vehicles also faces many challenges. The core components of new energy vehicles, such as batteries, motors, and electronic control systems, are very different from traditional vehicles, which requires detection technology and methods to keep pace with the times.

[0003] The battery is the core component of the new energy vehicle, and its performance directly affects the vehicle's range, power performance, and safety. Battery system detection includes battery capacity detection, battery power detection, battery voltage detection, battery internal resistance detection, and battery charge and discharge performance detection. When detecting the power of the new energy vehicle battery, a detection probe is usually used to contact the two poles of the battery to detect and control the current and voltage changes of the battery, and the battery power related data is calculated according to the detection results. Therefore, the detection probe is important in the process of detecting the power of the new energy vehicle battery.

[0004] The detection probe in the prior art needs to be in contact with the two poles of the detection battery first, and then the needle head can be pressed on the detection battery for detection by pressing and sliding the sleeve. After long-term use of the detection probe, the inner wall of the sliding sleeve and the outer wall of the needle sleeve are easily worn due to the long-term back and forth movement of the sliding sleeve on the surface of the needle sleeve, which makes the guidance inaccurate and even causes the jamming. Therefore, we propose a probe for a new energy vehicle power detection system. SUMMARY

[0009] Optionally, an oil injection port for injecting lubricating oil into the containing groove is arranged on the outer wall of the sliding sleeve, and a rubber plug is arranged in the oil injection port.

[0010] Optionally, the outer wall of the sliding sleeve is further provided with two arc-shaped openings, and a filter screen is installed in each of the two arc-shaped openings; a sleeve plate is connected to the bottom end of the mounting plate through a plurality of elastic members, and the sleeve plate can block the two arc-shaped openings.

[0014] Optionally, a rotating plate is rotatably installed at the bottom end of each of the two arc-shaped blocks, a notch matching the moving rod is formed at the end, close to the rotating part, of each of the two rotating plates, two second sliding grooves are formed at the bottom end of each of the two rotating plates, a second sliding block is installed in each of the two second sliding grooves, and a moving block is jointly installed at the end, away from the second sliding groove, of each of the two second sliding blocks.

[0015] Optionally, a first brush and a second brush are respectively installed in the two moving blocks, and the first brush and the second brush are a nylon brush and a bristle brush, respectively.

[0016] The beneficial effects of the present application are as follows:

[0017] 1. In the application, through the cooperation of the automatic lubricating mechanism and the automatic cleaning mechanism, automatic lubrication between the sliding sleeve and the needle sleeve can be realized, ensuring that the sliding sleeve can maintain smooth sliding adjustment on the surface of the needle sleeve for a long time, so as to ensure that the probe can still have good performance after long-term use and reduce the wear between the sliding sleeve and the needle sleeve.

[0018] 2. In the application, due to the limited adsorption effect of the sponge pad on the lubricating oil during use, part of the lubricating oil will overflow from the bottom end of the sliding sleeve. At this time, the related components of the automatic cleaning mechanism can be used in cooperation to drive the two oil absorption pads to abut against the bottom end of the sliding sleeve and adsorb the excess lubricating oil. The two electric sliding blocks move in the same direction in the circular groove, which drives the two oil absorption pads to move synchronously at the position of the bottom end of the sliding sleeve, so that the two oil absorption pads can more comprehensively adsorb and clean the lubricating oil overflowing from the bottom end of the sliding sleeve, improving the cleaning effect of the excess lubricating oil.

[0019] 3. In the application, when the two oil absorption pads adsorb lubricating oil, the extension ends of the two first electric telescopic rods at the bottom end of the two rotating blocks are controlled to extend downward, driving the two oil absorption pads to move downward to a position close to the threaded part. At this time, as the extension ends of the two second electric telescopic rods extend, the two oil absorption pads abut against the threaded part. As the extension ends of the corresponding two first electric telescopic rods continue to extend downward, the lubricating oil adsorbed in the two oil absorption pads can be automatically applied to the surface of the threaded part. The two electric sliding blocks move in the circular groove, so that the two oil absorption pads can more evenly apply lubricating oil to the surface of the threaded part, facilitating smoother rotation of the nut.

[0020] 4. In the application, after the probe body is used, the first brush and the second brush can be driven to automatically clean the surface of the probe body in sequence through the cooperation between the related components of the automatic cleaning mechanism, ensuring better cleaning effect of the surface of the probe body and maintaining the stability of the probe body in battery detection.

DETAILED DESCRIPTION

[0034] The embodiments of the technical solutions of the present application will be described in detail below with reference to the drawings. The following embodiments are only used to more clearly illustrate the technical solutions of the present application, and therefore only serve as examples, and cannot limit the protection scope of the present application.

[0035] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application should have the ordinary meaning as understood by one of ordinary skill in the art to which this invention pertains.

[0036] like Figures 1-11 As shown, a probe for a new energy vehicle power detection system includes a mounting plate 1 and a needle sleeve 3. A sliding sleeve 2 is mounted on the bottom end of the mounting plate 1. The needle sleeve 3 is slidably mounted inside the mounting plate 1 and the sliding sleeve 2. The needle sleeve 3 and the mounting plate 1 are connected by a spring 4. A threaded portion 5 is provided on the outer wall of the bottom end of the needle sleeve 3. A nut 6 for limiting and fixing the sliding sleeve 2 is threaded on the outer wall of the threaded portion 5. A probe body 7 is mounted on the bottom end of the needle sleeve 3. An automatic lubrication mechanism for lubricating the surface of the needle sleeve 3 is provided inside the sliding sleeve 2. An automatic cleaning mechanism for cleaning the surface of the probe body 7 is provided at the bottom end of the mounting plate 1.

[0037] As an optimized technical solution of the present invention, the automatic lubrication mechanism includes a receiving groove 17 opened inside the sliding sleeve 2. Multiple guide grooves 18 are formed on the inner wall of the receiving groove 17. Guide blocks 22 are slidably installed inside each of the multiple guide grooves 18. A metal ring 20 is commonly installed at the end of each guide block 22 away from the guide groove 18. A piston 21 is installed at the top of the metal ring 20. During the up-and-down movement of the metal ring 20 inside the receiving groove 17, the multiple guide blocks 22 move and guide synchronously up and down within the corresponding guide grooves 18, preventing positional deviation of the metal ring 20 during its up-and-down movement. This facilitates better driving of the piston 21 to push the lubricating oil inside the receiving groove 17 upwards and discharge it.

[0038] As a technical optimization of the present invention, the inner wall of the top of the sliding sleeve 2 is provided with multiple oil drain ports 23, and a sponge pad 16 for adsorbing and temporarily storing lubricating oil is installed on the inner wall of the sliding sleeve 2. The metal ring 20 drives the piston 21 to move upward inside the receiving groove 17, and after pushing the lubricating oil, the lubricating oil can be discharged outward through the multiple oil drain ports 23 to the inside of the sponge pad 16 for adsorption and temporary storage, so as to facilitate subsequent lubrication of the outer wall of the needle sleeve 3; for example... Figure 4 As shown, the sponge pad 16 is installed in the annular groove opened in the inner wall of the sliding sleeve 2, so that while the sliding sleeve 2 moves back and forth on the surface of the needle sleeve 3, the sponge pad 16 is prevented from directly rubbing against the outer wall of the needle sleeve 3.

[0039] As a technical optimization of the present invention, the outer wall of the sliding sleeve 2 is provided with an oil injection port 14 for injecting lubricating oil into the receiving groove 17, and the inside of the oil injection port 14 is covered with a rubber plug 15.

[0040] As a technical optimization of the present invention, the outer wall of the sliding sleeve 2 is also provided with two arc-shaped openings, and a filter screen 19 is installed inside each of the two arc-shaped openings. The bottom end of the mounting plate 1 is connected to the sleeve plate 10 through multiple elastic elements 9. The sleeve plate 10 can seal the two arc-shaped openings. When the sleeve plate 10 is in a static state, it is located on the surface of the sliding sleeve 2 and seals the two arc-shaped openings. When it is necessary for the two arc-shaped openings to be open, the sleeve plate 10 can be pushed upward to move it above the two arc-shaped openings.

[0041] As a technical optimization of the present invention, the automatic cleaning mechanism includes a circular groove 8 opened at the bottom of the mounting plate 1. Two electric sliders 24 are installed inside the circular groove 8, and mounting bases 25 are installed at the bottom of each of the two electric sliders 24. Two arc-shaped motors are preset inside the circular groove 8, which can drive the two electric sliders 24 and the mounting bases 25 to move in a semi-circular motion inside the circular groove 8.

[0042] As a technical optimization of the present invention, a rotating block 26 is rotatably installed inside each of the two mounting bases 25. Two first electric telescopic rods 27 are installed at the bottom of each of the two rotating blocks 26, and a moving rod 11 is installed at the telescopic ends of the two first electric telescopic rods 27. A first driving device is pre-installed on the outer wall of one side of each of the two mounting bases 25. The output ends of the two first driving devices are respectively connected to the rotating parts at one end of the two rotating blocks 26, thereby enabling the two rotating blocks 26 to rotate and adjust inside the corresponding mounting base 25. During the telescopic process of the two first electric telescopic rods 27, the moving rod 11 can be moved up and down at the bottom of the rotating block 26 for adjustment.

[0043] As a technical optimization of the present invention, a first sliding groove 28 is provided on the outer wall of the two moving rods 11 that are close to each other. A first slider 32 is installed inside the two first sliding grooves 28. An arc-shaped block 12 is installed at the end of the two first sliders 32 away from the first sliding groove 28. An electromagnet 37 is installed on the outer wall of the two arc-shaped blocks 12 away from the first sliders 32. A second electric telescopic rod 36 is installed inside the two first sliders 32. An oil-absorbing pad 33 for absorbing and cleaning the overflowing lubricating oil is installed at the telescopic end of the two second electric telescopic rods 36. Each of the two first slide grooves 28 is equipped with a first linear motor. The two first linear motors can drive the two first sliders 32 to move up and down inside the corresponding first slide grooves 28, thereby driving the two arc blocks 12 to move up and down synchronously on one side of the outer wall of the moving rod 11. The electromagnets 37 installed on one side of the outer wall of the two arc blocks 12 can be magnetically attracted and fixed to the metal ring 20 after being energized, so that the two arc blocks 12 can drive the metal ring 20 to move up and down synchronously inside the receiving groove 17 during the up and down movement. During the extension and retraction of the two second electric telescopic rods 36, the two oil-absorbing pads 33 can move and adjust synchronously.

[0044] As a technical optimization of the present invention, a rotating plate 13 is rotatably mounted on the bottom end of each of the two arc-shaped blocks 12. Each of the two rotating plates 13 has a notch 34 at the end near the rotating part, which is adapted to the moving rod 11. Two second sliding grooves 35 are formed at the bottom end of each of the two rotating plates 13. A second slider 38 is installed inside each of the two second sliding grooves 35. A moving block 29 is mounted on the end of each of the two second sliders 38 away from the second sliding groove 35. A second driving device is pre-installed at the bottom end of each of the two arc-shaped blocks 12. The output ends of the two second driving devices are respectively connected to the rotating parts at one end of each of the two rotating plates 13, thereby enabling the two rotating plates 13 to rotate and adjust at the bottom end of the corresponding arc-shaped block 12. A second linear motor is pre-installed inside each of the two second sliding grooves 35. The two second linear motors can drive the two second sliders 38 to move back and forth inside the corresponding second sliding grooves 35, thereby driving the moving block 29 to move and adjust at the bottom end of the rotating plate 13.

[0045] As a technical optimization of the present invention, a first brush 30 and a second brush 31 are respectively installed inside the two moving blocks 29. The first brush 30 and the second brush 31 are a nylon brush and a bristle brush, respectively. After detecting the battery power with the probe body 7, carbon deposits will adhere to the surface of the probe body 7. At this time, a bristle brush with moderate hardness can be used to remove large residues first, and then a softer nylon brush can be used to clean the needle tip gaps of the probe body 7 to ensure a good cleaning effect on the surface of the probe body 7.

[0046] In this invention, when using the device, the user first installs two probes in the relevant testing equipment, then places the new energy vehicle battery to be tested inside the testing equipment and clamps it stably. Next, the bottom ends of the two probe bodies 7 are respectively connected to the positive and negative terminals of the battery pack, ensuring vertical contact and appropriate pressure. The testing equipment measures the battery's open-circuit voltage through the probes. After resting for 30 minutes to ensure more accurate measurement data, the battery's measurement data is obtained. By comparing the measured open-circuit voltage with the corresponding OCV-SOC curve provided by the battery manufacturer, the SOC is calculated, thus obtaining the battery's capacity data and completing the testing of the new energy vehicle battery's capacity.

[0047] During use, the sliding sleeve 2 needs to move back and forth repeatedly on the surface of the needle sleeve 3, which can easily lead to wear on the inner wall of the sliding sleeve 2. This can result in inaccurate guidance of the sliding sleeve 2 on the needle sleeve 3, or even jamming of the sliding sleeve 2 on the surface of the needle sleeve 3. To ensure that the sliding sleeve 2 can still slide flexibly on the surface of the needle sleeve 3 after long-term use, it is necessary to lubricate the sliding sleeve 2 and the needle sleeve 3 regularly. When it is necessary to lubricate the inner wall of the sliding sleeve 2, the rubber stopper 15 can be removed first, and then lubricating oil can be injected into the interior of the receiving groove 17 through the oil filling port 14. At this time, the metal ring 20 and the piston 21 are located at the bottom of the receiving groove 17, and the two moving rods 11 and other components located at the bottom of the mounting plate 1 are in a state of... Figure 1 In the initial state shown, after the two electromagnets 37 are energized and activated, they can magnetically attract the metal ring 20. Then, the two first sliders 32 are controlled to move upward inside the corresponding first sliding grooves 28, driving the two arc blocks 12, electromagnets 37, the magnetically attracted metal ring 20, and piston 21 to move upward together. This allows piston 21 to push the lubricating oil inside the receiving groove 17 upward. The lubricating oil can be discharged outward through multiple oil drain ports 23 to the inner wall of the sponge pad 16 for adsorption. During the process of the sliding sleeve 2 moving up and down on the surface of the needle sleeve 3, the lubricating oil overflowing from the sponge pad 16 is automatically applied to the contact area between the needle sleeve 3 and the sliding sleeve 2, achieving an automatic lubrication effect between the sliding sleeve 2 and the needle sleeve 3. This ensures that the sliding sleeve 2 can maintain smooth sliding adjustment on the surface of the needle sleeve 3 for a long time, while also ensuring that the probe can still have good performance after long-term use.

[0048] Because the sponge pad 16 mentioned above has limited absorption effect on lubricating oil during use, some lubricating oil will overflow from the bottom of the sliding sleeve 2. To avoid this overflowing lubricating oil affecting the use of the probe, it can be removed as follows: Figure 1As shown, the telescopic ends of the two first electric telescopic rods 27 at the bottom of the two rotating blocks 26 extend downward together, driving the two moving rods 11 to move downward together until the oil-absorbing pads 33 at the top of the two arc-shaped blocks 12 move downward to a position flush with the bottom of the sliding sleeve 2. Then, the telescopic ends of the second electric telescopic rods 36 inside the two first sliders 32 extend together, which can drive the two oil-absorbing pads 33 to abut against the bottom of the sliding sleeve 2 and absorb the overflowing excess lubricating oil. With the two electric sliders 24 moving in the same direction in the arc inside the circular groove 8, the two oil-absorbing pads 33 can move and adjust synchronously at the bottom of the sliding sleeve 2, so that the two oil-absorbing pads 33 can more comprehensively absorb and clean the lubricating oil overflowing from the bottom of the sliding sleeve 2, improving the cleaning and removal effect of this part of excess lubricating oil.

[0049] To recover and reuse the lubricating oil temporarily absorbed inside the two oil-absorbing pads 33, the telescopic ends of the two second electric telescopic rods 36 can be controlled to retract and return to their original positions, moving the two oil-absorbing pads 33 to the top of the corresponding arc-shaped block 12. Then, the telescopic ends of the two first electric telescopic rods 27 can be controlled to retract and return to their original positions, causing the top ends of the two moving rods 11 to abut against the bottom end of the corresponding rotating block 26. Subsequently, the two first sliders 32 can be controlled to move the arc-shaped block 12 and the oil-absorbing pads 33 upward together within the corresponding first sliding groove 28 for adjustment, so that the two arc-shaped blocks 12 and the oil-absorbing pads 33 slide... When the surface of sleeve 2 moves upward, it can push sleeve 10 upward until sleeve 10 moves upward to its maximum height. At this time, the two oil-absorbing pads 33 are flush with the two arc-shaped openings. Finally, the telescopic ends of the two second electric telescopic rods 36 are extended together, pushing the two oil-absorbing pads 33 to abut against the filter screens 19 set inside the two arc-shaped openings respectively, and squeezing the two oil-absorbing pads 33. This causes the lubricating oil adsorbed inside the two oil-absorbing pads 33 to enter the receiving tank 17 for recycling after being filtered by the filter screens 19, so that it can be used again later and avoids the waste of this part of the lubricating oil.

[0050] Meanwhile, when lubricating oil is absorbed inside the two oil-absorbing pads 33, the telescopic ends of the two first electric telescopic rods 27 at the bottom of the two rotating blocks 26 are controlled to extend downward, causing the two oil-absorbing pads 33 to continue moving downward to a position close to the threaded part 5. At this time, as the telescopic ends of the two second electric telescopic rods 36 extend, the two oil-absorbing pads 33 come into contact with the threaded part 5. As the telescopic ends of the corresponding two first electric telescopic rods 27 continue to extend downward, the lubricating oil absorbed inside the two oil-absorbing pads 33 can be automatically applied to the surface of the threaded part 5. With the two electric sliders 24 moving inside the circular groove 8, the two oil-absorbing pads 33 can more evenly apply lubricating oil to the surface of the threaded part 5, so that the nut 6 can be tightened more smoothly in the subsequent process.

[0051] After the probe body 7 detects the battery power, carbon deposits will adhere to its surface. At this time, it can be used as follows: Figure 11 As shown, firstly, control the two first electric telescopic rods 27 at the bottom of one of the rotating blocks 26 to extend to their maximum length together, and drive one of the moving rods 11 to move downward to the lowest position. Then, control the rotating plate 13 at the bottom of one of the arc-shaped blocks 12 to rotate towards the probe body 7 to a horizontal state. At this time, one of the moving blocks 29 and the second brush 31 can be driven to rotate to the top of the rotating plate 13, and the second brush 31 is located below the probe body 7. Control the two corresponding second sliders 38 to move towards one end inside the second slide groove 35, and drive the pig bristle brush with appropriate hardness to remove large impurities at the bottom of the probe body 7.

[0052] It can also control the rotating plate 13 to drive the moving block 29 and the second brush 31 to rotate and adjust at the bottom end of the arc block 12. In conjunction with the rotation of one of the rotating blocks 26 inside the mounting base 25 towards the probe body 7, and the extension and retraction of the extension ends of the two first electric telescopic rods 27, the second brush 31 can clean the impurities on the outer wall of the probe body 7.

[0053] Simultaneously, the movement of the corresponding electric slider 24 inside the circular groove 8 drives the second brush 31 to more comprehensively remove impurities from the outer wall of the probe body 7; subsequently, multiple components such as the moving rod 11 at the bottom of another rotating block 26 are controlled to drive a relatively soft nylon brush to clean the needle tip gaps of the probe body 7, ensuring a good cleaning effect on the surface of the probe body 7, so as to maintain the stability of the probe body 7 for battery detection.

[0054] If the nut 6 needs to be tightened or loosened during probe installation into the testing equipment to adjust the compression of the spring 4, thereby adjusting the pressure of the probe tip 7 against the battery terminal, then... Figure 1 and Figure 10 As shown, control Figure 1 The two rotating plates 13 are adjusted to a vertical position at the bottom of the corresponding arc-shaped block 12, which drives the two moving blocks 29 to rotate to a position close to the nut 6. Then, the two second sliders 38 are controlled to move upward together in the corresponding second slide groove 35, which drives the two moving blocks 29 to move upward to the same height as the nut 6. At this time, the two moving blocks 29 abut against the outer walls of the two sides of the nut 6 respectively. With the help of the two electric sliders 24, they rotate in the same direction to a certain angle in the circular groove 8, which can drive the nut 6 to automatically tighten or loosen on the surface of the threaded part 5. There is no need to remove the probe from the detection equipment and then manually tighten it with a wrench, which improves the convenience of tightening the nut 6.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
