Description

Technical Field

[0001] This application relates to the field of automotive repair equipment technology, and in particular to an electrical safety testing device for new energy vehicles. Background Technology

[0002] Amid the global push for environmental protection and sustainable development, the automotive industry is undergoing profound changes, with new energy vehicles becoming the core direction for the future development of the automotive industry due to their significant advantages of low or even zero emissions.

[0003] With the widespread application of new energy vehicles, their electrical safety issues have gradually become prominent. The electrical systems of new energy vehicles are more complex than those of traditional gasoline vehicles, and the operating voltage is significantly higher. This undoubtedly increases electrical safety risks. For example, if the insulation performance of the high-voltage system fails, it could very likely lead to electric shock accidents, seriously threatening the lives of passengers. Furthermore, potential imbalances can cause electromagnetic interference, affecting the normal operation of the vehicle's electronic equipment and even negatively impacting the vehicle's handling stability. Therefore, to effectively ensure the safe operation of new energy vehicles, accurate and efficient testing of their electrical safety is particularly important and urgent, requiring the use of specialized testing equipment.

[0004] Patent CN220154562U discloses an automotive electrical testing instrument. This prior art adds a flip-up cover to the top of the electrical testing instrument, and sets a rubber sealing block and a sponge pad on the inside of the cover to effectively protect the interface and screen of the testing instrument and prevent dust and moisture from getting in. At the same time, an embedded block and a light sheet are set at the head of the cover, which can be used as a backup light source, making it convenient to use at night or in poor lighting areas, thus improving the convenience of using the automotive electrical testing instrument.

[0005] However, the above has some shortcomings in actual use: 1. Sponges are designed to absorb dust and moisture. If they are used to cover the screen for a long time, the particles (dust, metal shavings) they absorb may scratch the screen during friction. At the same time, sharp objects inside the device (plug probes) can easily puncture or scratch the thin sponge pad during storage, directly damaging the screen.

[0006] 2. When the device is used outdoors or in bright light, the glare from the screen surface can seriously interfere with the user's observation and interpretation of the data. Strong light reflection can obscure the displayed content, forcing the operator to repeatedly adjust the viewing angle to find a readable position. This not only reduces the detection efficiency but also increases the risk of misreading key data, affecting the accuracy and safety of the work.

[0007] Therefore, based on the above-stated viewpoints, there is still room for improvement in existing testing equipment. Summary of the Invention

[0008] To address the aforementioned problems, this application provides an electrical safety testing device for new energy vehicles. Includes a suitcase with a flip-top lid.

[0009] The suitcase has a set of display screens symmetrically arranged inside the top lid to display detection information.

[0010] The display screen is provided with a support bracket mechanism and a base mechanism for adjusting the position of the display screen on one side. The support bracket mechanism includes a set of symmetrically arranged vertical plates. Mounting plates are rotatably installed on both sides of the display screen housing. A set of slots are symmetrically opened on both sides of the display screen housing around the mounting plates. The support bracket mechanism also includes a fixing component that is inserted into the slots to fix the display screen.

[0011] The base mechanism includes a strip plate rotatably mounted on the inner wall of the suitcase lid, and a set of electric cylinders connected to the vertical plate on the same side are symmetrically mounted on the side of the strip plate.

[0012] The support mechanism is equipped with a deflection mechanism, which includes multiple electric cylinders 2 that are rotatably mounted on the side of the vertical plate. The telescopic arm end of the electric cylinder 2 is rotatably connected to the mounting plate.

[0013] Preferably, the base mechanism also includes a motor mounted on the upper side of the strip plate and whose drive end is connected to the shaft between the strip plate and the suitcase, thereby driving the strip plate to rotate on the top cover of the suitcase.

[0014] Preferably, the inner wall of the suitcase lid is equipped with an annular guide rail with the same center as the motor drive end, and a slide block that slides on the annular guide rail is installed on the same side of the strip plate and the annular guide rail.

[0015] Preferably, a strip slide rail 1 is installed on one side of each vertical plate on the same side as the strip plate and the vertical plate. A strip slide rail 2 with its end connected to the vertical plate on the same side is slidably arranged inside the strip slide rail 1. When the vertical plate is moved by the extension and retraction of the electric cylinder 1, the strip slide rail 2 is moved on the strip slide rail 1.

[0016] Preferably, the fixing assembly includes multiple sets of L-shaped plates installed at the center of the side of the vertical plate and on one side of two adjacent slots. Rectangular rods aligned with the corresponding slots are inserted into the L-shaped plates, and a pull ring is installed at one end of each rectangular rod.

[0017] Preferably, the other end of the rectangular rod is fitted with a clip that inserts into the alignment slot, and a spring connects the clip to the inner side of the L-shaped plate.

[0018] Preferably, a bearing is installed inside the slot, and the outer diameter of the card is the same as the inner diameter of the bearing. The cooperation between the bearing and the card ensures that the display screen rotates normally around the card.

[0019] Preferably, an arc-shaped guide rail with its end connected to the vertical plate on the same side is installed on the inner side of the second strip slide rail, and a slider connected to the back plate of the corresponding display screen is slidably arranged inside the arc-shaped guide rail.

[0020] Preferably, it also includes a detection mechanism located inside the main compartment of the suitcase.

[0021] Preferably, a female buckle is installed on the side of the top cover of the suitcase, and a female buckle that matches the female buckle is installed on the same side of the main body of the suitcase.

[0022] In summary, this application includes at least one of the following beneficial technical effects: I. This application achieves redundancy and backup by configuring multiple displays. Even if one display fails, the remaining intact displays can still operate normally, effectively ensuring the continuous and stable operation of the equipment and the smooth execution of the testing process. Simultaneously, the base mechanism can automatically reposition the multiple displays without manual intervention, significantly improving the level of automation in the equipment.

[0023] Second, this application relies on the linkage of the support mechanism to allow the display panel to rotate around its own axis. In the idle state, the display surface can face the inside of the suitcase lid, with its hard back facing the detection mechanism, avoiding scratch damage to the display surface from the sharp parts of the detection mechanism. This design replaces the traditional sponge protection solution, fundamentally avoiding the problem of dust transferring to the display screen after the sponge has absorbed dust, and achieving reliable protection for the display surface.

[0024] Third, this application utilizes the synergistic effect of a deflection mechanism. When direct sunlight reduces the visibility of the display screen, the upper display screen can be driven to deflect forward around the connection point between the slot and the card, thus providing shading protection for the lower display screen and effectively eliminating strong light interference. This ensures that operators can accurately read critical data and avoids affecting the accuracy and safety of their work due to insufficient visibility. Attached Figure Description

[0037] The following is in conjunction with the appendix Figures 1-10 The embodiments of this application will be described in detail.

[0038] This application discloses an electrical safety testing device for new energy vehicles. Relying on the linkage of the support mechanism, the display panel can be deflected around its own axis. In the idle state, the display surface can face the inside of the suitcase lid, with its hard back facing the testing mechanism, avoiding scratch damage to the display surface from the sharp parts of the testing mechanism. This design replaces the traditional sponge protection solution, fundamentally avoiding the problem of dust transferring to the display screen after the sponge has absorbed dust, and achieving reliable protection for the display surface.

[0039] Example 1: like Figure 1As shown, the device includes a carrying case 1 with an openable top cover. A set of display screens 5, which are symmetrically arranged inside the top cover of the carrying case 1 to display test information, is also included. The carrying case 1 also includes a testing mechanism 6 located inside the main compartment of the carrying case 1. The testing mechanism 6 can perform various safety tests on new energy vehicles and display the test data on the display screens 5 for the operator to view. The carrying case 1 is used to store the display screens 5 and the testing mechanism 6, and can be opened directly when needed.

[0040] like Figure 1 As shown, there are two displays 5. If one of them is damaged, the other can still be used normally. In addition, the display 5 is a touch screen, which makes it convenient for operators to operate manually on the display 5.

[0041] Furthermore, the opening angle of the top cover of the suitcase 1 and the main box is only ninety degrees, so that the suitcase 1 automatically forms an L shape when the top cover is opened.

[0042] like Figure 4 As shown, a male buckle 7 is installed on the side of the top cover of the suitcase 1, and a female buckle 8 that matches the male buckle 7 is installed on the same side of the main compartment of the suitcase 1. After the top cover is closed, the male buckle 7 and the female buckle 8 are locked together to close the suitcase 1.

[0043] like Figure 1 and Figure 10 As shown, testing organization 6 includes: The control module 61 uses an ARM Cortex-M4 core microprocessor and peripheral circuits.

[0044] DC high voltage module 62 is used to generate the DC high voltage required for insulation resistance detection.

[0045] The current measurement module 63 includes a micro-current measurement unit and a high-current measurement unit.

[0046] The resistance measurement module 64 includes megohm-level and milliohm-level measurement units.

[0047] Operation module 65 consists of physical operation buttons for the mechanism. Operators can manually control the various modules within the testing mechanism 6 through operation module 65.

[0048] Power module 66 provides a stable power supply for each component.

[0049] Interface module 67 includes various detection probe interfaces and communication interfaces.

[0050] Signal conditioning module: amplifies, filters, and isolates the measurement signal.

[0051] Safety protection module: Includes overvoltage, overcurrent, and short-circuit protection circuits.

[0052] The following technologies are achieved through the cooperation of various modules: Megohmmeter Function Technology: The control module 61 sets the output voltage value according to the detection requirements, controls the DC high voltage module 62 to generate the corresponding DC high voltage, applies the high voltage to both ends of the automotive circuit under test, the current measurement module 63 collects the current flowing through the resistor under test; the signal conditioning module amplifies and filters the current signal; the data after A / D conversion is transmitted to the control module 61, the resistance value under test is calculated by R=U / I, and the insulation resistance value is displayed on the display screen 5.

[0053] Milliohm meter function technology: The control module 61 sets a suitable constant current value according to the range of the resistance being measured, and the constant current source circuit generates the set constant current, which flows through the resistance being measured; the voltage sampling circuit (using a high-precision differential amplifier, which only measures the voltage drop across the resistance being measured, and is not affected by the lead resistance and contact resistance in the current loop) measures the voltage drop across the resistance being measured; the current measurement module 63 measures the actual current value flowing through; the two signals are respectively converted by A / D and transmitted to the control module 61 to calculate and display the resistance value being measured.

[0054] Insulation resistance testing technology for charging sockets: The operator connects the interface module 67 to the socket under test; selects the corresponding socket type and testing standard; the control module 61 controls the switching switch matrix (the switching switch matrix is ​​composed of high-voltage relays, controlled by the control module 61 to switch between different measurement points); selects the first set of measurement points; controls the megohmmeter function to apply the specified DC high voltage, measures and records the insulation resistance value; controls the discharge circuit to discharge the circuit under test, switches to the next set of measurement points, repeats the operation multiple times, and after completing the measurement of all specified points, displays the test information on the display screen 5.

[0055] Potential equalization detection technology: The operator reliably connects the connection terminal to the vehicle chassis; connects the conductive component to the probe (including alligator clips, probes, magnetic connectors, etc. to accommodate conductive components of different shapes and positions) to the first component under test. The system automatically measures the resistance value between the component and the electrical platform and records the measurement result; prompts the operator to connect the probe to the next component under test, or automatically switches to the next channel (if a multi-probe configuration is used, the control module 61 can automatically complete the resistance measurement between multiple conductive components according to the preset detection program). Repeat the steps to complete the measurement of all conductive components and the electrical platform, and measure the resistance value between each conductive component in sequence according to the preset program; after all measurements are completed, the results are displayed on the display screen 5.

[0056] Example 2: Based on Example 1, such as Figure 1 , Figure 2 , Figure 5 and Figure 7As shown, a support mechanism 3 for supporting itself is provided on one side of the display screen 5. The support mechanism 3 includes a set of symmetrically arranged vertical plates 31. Mounting plates 32 are rotatably installed on both sides of the outer shell of the display screen 5. When the display screen 5 is not in use, it can be rotated around the rotatable connection between the display screen 5 and the mounting plate 32 so that the display surface of the display screen 5 faces the inner wall of the upper cover of the carrying case 1. In this way, the display surface will not face the detection mechanism 6 during storage, which can effectively avoid damage to the display surface of the display screen 5 by the sharp part of the detection mechanism 6 during transportation.

[0057] like Figure 7 and Figure 8 As shown, a set of slots 33 are symmetrically opened on both sides of the outer shell of the display screen 5 around the mounting plate 32. The bracket mechanism 3 is also equipped with a fixing component that is inserted into the slot 33 to fix the display screen 5. When the display screen 5 is rotated into position, the fixing component and the slot 33 cooperate to fix the display screen 5.

[0058] like Figure 7 and Figure 8 As shown, the fixing assembly includes multiple sets of L-shaped plates 34, which are installed at the center of the side of the vertical plate 31 and located on one side of two adjacent slots 33; rectangular rods 35 are inserted into the L-shaped plates 34 and aligned with the corresponding slots 33, and a pull ring 37 is installed at one end of the rectangular rods 35, so that the operator can manually pull the rectangular rods 35 to move them.

[0059] like Figure 8 As shown, the other end of the rectangular rod 35 is equipped with a clip 38 that can be inserted into the alignment slot 33. A spring 36 is connected between the clip 38 and the inner side of the L-shaped plate 34. When the clip 38 is inserted into the slot 33 on the side of the display screen 5, the display screen 5 can be fixed. When the operator manually pulls the clip 38 out of the slot 33, the spring 36 will be compressed simultaneously. After being released, the spring 36 will rebound and drive the clip 38 to reset.

[0060] In summary, when rotating the display screen 5, one person first pulls the two pull rings 37 corresponding to the display screen 5 to be rotated outwards, causing the locking piece 38 to move out of the currently inserted slot 33, while compressing the spring 36; then another person rotates the display screen 5 so that its other side faces forward, and aligns another set of slots 33 on the display screen 5 with the two locking pieces 38; finally, the two pull rings 37 are released, and the spring 36 rebounds, causing the two locking pieces 38 to insert into the aligned slots 33, thus completing the re-fixing of the display screen 5.

[0061] like Figure 3 , Figure 5 and Figure 9As shown, the support mechanism 3 is equipped with a deflection mechanism 4, which includes multiple electric cylinders 41 rotatably mounted on the side of the vertical plate 31. The telescopic arm ends of the electric cylinders 41 are rotatably connected to the mounting plate 32. When sunlight shines on the display screen 5, making it difficult for the operator to observe, the two upper electric cylinders 41 are extended, causing the upper display screen 5 to deflect forward around the connection between the slot 33 and the clip 38 via the two mounting plates 32. This allows the upper display screen 5 to shield the lower display screen 5 from the sun, enabling the operator to clearly observe the information displayed on the lower display screen 5.

[0062] The slot 33 contains a bearing, and the outer diameter of the clip 38 matches the inner diameter of the bearing. Through the cooperation between the bearing and the clip 38, the display screen 5 can be smoothly deflected around the clip 38.

[0063] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the system also includes a base mechanism 2 for adjusting the position of the display screen 5. The base mechanism 2 includes a strip plate 22 rotatably mounted on the inner wall of the upper cover of the suitcase 1. A set of electric cylinders 26 are symmetrically mounted on the side of the strip plate 22, and the electric cylinders 26 are connected to the vertical plate 31 on the same side. By extending the electric cylinders 26, the vertical plate 31 and the display screen 5 can be moved away from the upper cover of the suitcase 1, increasing the distance between them and preventing the upper cover of the suitcase 1 from obstructing the rotation operation of the display screen 5.

[0064] like Figure 5 and Figure 6 As shown, the base mechanism 2 also includes a motor 23 mounted on the upper side of the strip plate 22. The drive end of the motor 23 is connected to the shaft between the strip plate 22 and the carrying case 1. When the lower display screen 5 is damaged, the motor 23 can drive the strip plate 22 to rotate on the top cover of the carrying case 1, causing the two display screens 5 to rotate synchronously, thus swapping the positions of the two display screens 5. In this way, the lower display screen 5 can still be used for normal display, while the damaged upper display screen 5 can continue to provide shade for the lower display screen 5, ensuring the normal progress of the testing work. After the testing is completed, the damaged display screen 5 can be repaired.

[0065] like Figure 6 As shown, an annular guide rail 21 is installed on the inner wall of the lid of the suitcase 1. The annular guide rail 21 is concentrically arranged with the drive end of the motor 23. A slide block that can slide on the annular guide rail 21 is installed on the side of the strip plate 22 on the same side as the annular guide rail 21. When the strip plate 22 rotates, it will drive the slide block to slide along the annular guide rail 21, effectively improving the stability of the strip plate 22 when rotating.

[0066] like Figure 6As shown, on the same side of the strip plate 22 and the vertical plate 31, a strip rail 24 is installed on one side of each vertical plate 31. A second strip rail 25 is slidably disposed within the first strip rail 24, and the end of the second strip rail 25 is connected to the vertical plate 31 on the same side. When the electric cylinder 26 extends and retracts to move the vertical plate 31, it will simultaneously drive the second strip rail 25 to slide within the first strip rail 24. The cooperation of the two improves the stability of the vertical plate 31 during movement and prevents it from deviating in direction.

[0067] like Figure 9 As shown, on one side of each electric cylinder 41, an arc-shaped guide rail 42 is installed on the inner side of the second strip slide rail 25, with its end connected to the vertical plate 31 on the same side. A slider 43, which is connected to the back plate of the corresponding display screen 5, is slidably disposed inside the arc-shaped guide rail 42. When the electric cylinder 41 extends or retracts, causing the display screen 5 to deflect around the connection between the slot 33 and the clip 38, it will simultaneously drive the slider 43 to slide along the arc-shaped guide rail 42, improving the stability of the display screen 5 when it deflects.

[0068] In summary, the complete operation process of rotating display screen 5 is as follows: First, control the electric cylinder 26 to extend to its maximum length, increasing the distance between the vertical plate 31 and the top cover of the carrying case 1; then rotate display screen 5 according to the aforementioned steps; after rotating to the correct position, control the electric cylinder 26 to retract to its shortest length. When the lower display screen 5 is damaged, start the motor 23 driving the strip plate 22 to rotate the two vertical plates 31 and the display screen 5 on them until the positions of the two display screens 5 are swapped, ensuring that the normally functioning display screen 5 is at the bottom; if sunlight affects observation, control the two electric cylinders 41 at the top to extend, and drive the upper display screen 5 to deflect forward through the mounting plate 32 to achieve sunshade, making it easier to observe the information on the lower display screen 5; when sunshade is not needed, control the electric cylinder 41 to retract to its shortest length, which will drive the upper display screen 5 to deflect in the opposite direction and reset.

[0069] This application also discloses a method for using an electrical safety testing device for new energy vehicles, the specific steps of which are as follows: S1. Screen Rotation: After opening the suitcase 1, rotate the display screen 5 to face forward. Specifically, the operator first unfastens the male and female buckles 7 and 8 between the top cover of the suitcase 1 and the main box, and rotates the top cover of the suitcase 1 around the hinge to an L-shape. Then, one person pulls the two pull rings 37 corresponding to the display screen 5 to be rotated outward, causing the clip 38 to move out of the slot 33 and compress the spring 36. Another person rotates the display screen 5 so that the side to be used faces forward, and aligns another set of slots 33 on the display screen 5 with the two clips 38. Finally, release the pull rings 37, and the spring 36 rebounds, causing the clip 38 to insert into the aligned slots 33, thus completing the fixing of the display screen 5.

[0070] S2. Electrical Testing: The testing unit 6 is used to test various electrical values ​​of the new energy vehicle. The test data is displayed in real time on the display screen 5 below for easy recording by the operator.

[0071] S3. Position Swap: When the lower display screen 5 is damaged, swap the positions of the two display screens 5. Specific operation: Start the motor 23 driving the strip plate 22, which will drive the two vertical plates 31 and the display screens 5 on them to rotate until the positions of the two display screens 5 are swapped, ensuring that the normally functioning display screen 5 is at the bottom.

[0072] S4. Screen Sunshade: In strong light conditions, control the upper display screen 5 to deflect forward to shade the lower display screen 5. Specific operation: When sunlight makes it difficult to observe the display screen 5, control the two upper electric cylinders 41 to extend, causing the upper display screen 5 to deflect forward around the connection between the slot 33 and the clip 38 via the mounting plate 32, thus blocking the sunlight; when sunshade is not needed, control the electric cylinders 41 to retract to their shortest length, causing the upper display screen 5 to deflect in the opposite direction and reset.

[0073] S5. Device Storage: After rotating the display surface of the screen 5 to the back side, close the carrying case 1. Specific operation: Extend the control cylinder 26 to its maximum length and adjust the position of the screen 5; rotate the display surface of the lower screen 5 to the back side; retract the control cylinder 26 to its shortest length; close the top cover of the carrying case 1 onto the main case, and fasten the male buckle 7 and the female buckle 8 to complete the locking.

[0074] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects.

[0075] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
