[0002] With the rapid development of the new energy vehicle industry, DC charging piles, as the core infrastructure for replenishing energy for new energy vehicles, have seen continuous expansion in construction scale and a year-on-year increase in ownership. DC charging piles are exposed to complex outdoor environments for extended periods, and are susceptible to factors such as sunlight, rain, vibration, frequent plugging and unplugging, and power grid fluctuations. This can easily lead to faults such as abnormal electrical parameters, aging and damage to charging guns, excessive temperature rise of connectors, cracked shells, and loose and aging external wiring harnesses. These faults not only reduce charging efficiency but also pose safety hazards such as leakage and fire. Therefore, conducting comprehensive and accurate performance and appearance inspections of DC charging piles regularly is essential to ensure the safe and stable operation of charging piles and to standardize charging services. Currently, there are still many shortcomings in the testing equipment for DC charging piles in the industry: First, the equipment functions are scattered and the integration is low; second, the testing scope is limited, and traditional testing mostly uses equipment to collect electrical data, which only targets the equipment's operating status; third, the testing is not targeted enough, and conventional equipment can only complete the basic electrical data collection, making it difficult to simultaneously achieve integrated appearance screening and temperature monitoring of multiple parts such as the charging gun plug, pile shell, and external wiring harness, and it cannot complete comprehensive parameter verification at one time, resulting in poor testing completeness.

[0023] As a preferred embodiment, the first detection structure 2 further includes a pair of flip-up arm tubes 21, a pair of detection boxes 22, a docking gun head 23, a swing arm 24, a temperature detector 25, a cross-shaped electric slide rail 26, a base 27, an LED light 28, and a first camera 29; one end of each pair of flip-up arm tubes 21 is movably embedded in a flip-up groove 53, and the pair of detection boxes 22 are respectively fixedly disposed at the other end of the flip-up arm tubes 21, with the detection boxes 22 movably embedded in a storage groove 52. Each of the other ends of the pair of detection boxes 22 has a docking interface 62 on its right side wall, and one of the detection boxes 22 has an L-shaped mounting groove 61 on its front side wall that communicates with the right side wall, for docking guns. The head 23 is fixedly embedded in the interface 62 of one of the detection boxes 22, and the head 23 is electrically connected to the battery 18 and the integrated data board 19. One end of the swing arm 24 is movably embedded in the mounting groove 61, and the other end of the swing arm 24 can be located on the right side of the head 23.

The base 27 is L-shaped and fixedly mounted on the cross-shaped electric slide rail 26. The base 27 can move back and forth and up and down. The LED light 28 is movably mounted on one end of the base 27. The orientation can be adjusted by flipping. The first camera 29 is fixedly mounted on the other end of the base 27, and the first camera 29 corresponds to the LED light 28. The flip arm tube 21 is movably mounted in the flip groove 53 of the vehicle body 10. In the non-working state, the flip arm tube 21 drives the detection box 22 to be stored in the storage groove 52 at the top of the vehicle body 10, realizing the structure is folded up. When carrying out the inspection operation, the flip arm tube 21 is rotated outward to rotate the two detection boxes 22 to the working position. One of the detection boxes 22 is connected to the charging gun of the charging pile through the docking gun head 23 in the docking interface 62. The docking gun head 23 connects the battery 18 and the integrated data board 19. The charging pile power supply parameters are collected, and the swing arm 24 in the L-shaped mounting slot 61 is pulled out so that the temperature detector 25 at the end of the swing arm 24 is attached to the charging gun to collect the charging gun's working temperature data in real time.

Through the dual-axis drive of the cross-shaped electric slide rail 26, the base 27 can be driven to complete stepless position adjustment in both the front-back and up-down dimensions. A flip-up LED light 28 is movably mounted on one end of the base 27, and a first camera 29 is fixedly mounted on the other end. During detection, by adjusting the position of the base 27 and the illumination angle of the LED light 28, directional supplementary lighting is provided to the charging gun plug and interface area. This, together with the first camera 29, completes clear image acquisition at different angles and focal lengths, thereby identifying appearance defects such as wear, cracks, deformation, and damaged interface pins on the surface of the charging gun plug. All the above-mentioned electrical parameters, temperature data, and appearance images are transmitted to the integrated data board 19 through built-in circuitry for summary processing and storage.

[0025] As a preferred embodiment, the moving component 3 further includes a pair of hydraulic cylinder bodies 31, a pair of sliding arms 32, a pair of first lifting slide rails 33, a linkage frame 34, and a second lifting slide rail 35. The pair of hydraulic cylinder bodies 31 are symmetrically arranged on the lower inner wall of the storage compartment 10, located on the left and right sides of the battery 18. Each pair of hydraulic cylinder bodies 31 corresponds to a sliding groove 55. The pair of sliding arms 32 are movably inserted into the sliding grooves 55, with one end of each sliding arm 32 connected to the telescopic end of the hydraulic cylinder body 31. One end of each pair of first lifting slide rails 33 is connected to the other end of each sliding arm 32, and the first lifting slide rails 33 are symmetrically arranged on the left and right sides of the storage compartment 10. Both ends of the linkage frame 34 are fixedly connected to the first lifting slide rails 33, and the linkage frame 34 is located at the rear of the storage compartment 10 and can move up and down. One end of the second lifting slide rail 35 is vertically arranged in the middle of the linkage frame 34. The movement is achieved through two hydraulic cylinders... The main body 31 is symmetrically installed inside the lower wall of the storage box 10 and on both sides of the battery 18, and corresponds one-to-one with the sliding groove 55 on the side wall of the storage box 10. The hydraulic cylinder main body 31 outputs extension and retraction power to drive the corresponding sliding arm 32 to perform linear extension and retraction along the sliding groove 55. The outer end of the sliding arm 32 is connected to the first lifting slide rail 33 arranged in opposite directions. The two first lifting slide rails 33 together drive the linkage frame 34 on the rear side to complete the extension and retraction action synchronously. The linkage frame 34 can achieve overall lifting and lowering based on the first lifting slide rail 33. At the same time, the second lifting slide rail 35 is vertically installed in the middle of the linkage frame 34 to further extend the vertical adjustment stroke, thereby driving the second detection structure 4 mounted at the rear to complete the front and rear extension and multi-stage lifting and lowering action. During the equipment storage stage, the hydraulic cylinder retracts the sliding arm 32 and, in conjunction with the lifting slide rail reset, causes the linkage frame 34 and the second lifting slide rail 35 to retract to the rear position of the storage box 10, completing the mechanism retraction.

[0026] More specifically, the moving component 3 uses a pair of hydraulic cylinder bodies 31 as its power source. The two hydraulic cylinder bodies 31 are symmetrically fixedly installed on the lower inner wall of the chassis 10, located on the left and right sides of the battery 18, respectively. The installation positions of the hydraulic cylinder bodies 31 correspond one-to-one with the sliding grooves 55 opened at the bottom of the left and right side walls of the chassis 10. Each hydraulic cylinder body 31 has a corresponding sliding arm 32 connected to its telescopic end. The sliding arm 32 is movably inserted into the sliding groove 55 on the side wall of the chassis 10 and can perform linear reciprocating motion along the guide of the sliding groove 55. The two sliding arms 32... Two first lifting slide rails 33 are fixedly connected to the outer ends of the two first lifting slide rails 33, which are arranged symmetrically in opposite directions on the left and right sides of the vehicle body 10 to ensure balanced force. The left and right ends of the linkage frame 34 are fixedly mounted to the sliding ends of the two first lifting slide rails 33. Relying on the vertical drive of the first lifting slide rails 33, the linkage frame 34 can complete the overall vertical lifting adjustment on the rear side of the vehicle body 10. The middle part of the linkage frame 34 is vertically fixedly installed with a second lifting slide rail 35, thus forming a two-stage vertical lifting adjustment structure to further expand the range of vertical adjustment. During testing, the hydraulic cylinder body 31 outputs extension power, driving the sliding arm 32 to extend backward along the sliding groove 55. This causes the two first lifting slide rails 33 and the linkage frame 34 to move backward as a whole, disengaging the linkage frame 34 from its storage position on the rear side wall of the equipment box 10. Then, through the graded lifting adjustment of the first and second lifting slide rails 33 and 35, the second testing structure 4 mounted at the rear is moved to the corresponding testing height area of ​​the charging pile, achieving forward and backward extension and multi-stage lifting position adjustment of the second testing structure 4. When the equipment completes testing and enters the storage stage, the hydraulic cylinder body 31 retracts, driving the sliding arm 32 to retract forward along the sliding groove 55. Simultaneously, the first and second lifting slide rails 33 and 35 return to their lowest positions, causing the linkage frame 34 and the second lifting slide rail 35 to retract to their storage position on the rear side of the equipment box 10, completing the overall retraction of the moving component 3.

A second bolt 434 is screwed onto the other end of the first detection arm 431 and is tightened against the second detection arm 433. Several second cameras 435 are respectively embedded on the opposite sidewalls of one end of the second detection arm 433 and one end of the first detection arm 431.

[0029] More specifically, the detection unit 43 uses an L-shaped first detection arm 431 as a primary extension arm. One end of the first detection arm 431 is movably fitted into a first reversing groove 72 at the end of the mounting arm 42, allowing for 0-90 degree rotation adjustment around the fitting axis.

Tighten the first bolt 432 to secure the mounting end of the first testing arm 431, preventing the arm from rotating or shifting during testing. Then, rotate the second testing arm 433 90 degrees towards the rear of the equipment along the second reversing groove 73, making the second testing arm 433 perpendicular to the first testing arm 431, thereby widening the longitudinal testing width range of the testing device. Tighten the second bolt 434 to secure the second testing arm 433. The mounting end is locked; multiple second cameras 435 distributed on the mounting arm 42, the first detection arm 431, and the second detection arm 433 adjust their position and shooting angle synchronously with the arm body to form a multi-view imaging array covering the front, side, and wiring area of ​​the charging pile, and to collect images of the charging pile shell, external wiring harness, and wiring terminal parts from all directions; after the detection is completed, the second bolt 434 and the first bolt 432 are loosened in sequence, and the second detection arm 433 and the first detection arm 431 are flipped and reset to a folded state parallel to the corresponding arm body.

[0030] As a preferred embodiment, furthermore, when the second detection arm 433 is stored, the other end of the second detection arm 433 can be parallel and symmetrical with the other end of the first detection arm 431; after the first detection arm 431 is rotated 90 degrees, it is located on the left and right sides of the refurbishment box 10 to increase the detection length range; after the second detection arm 433 is rotated 90 degrees, it is located on the rear side of the refurbishment box 10 to increase the detection width range.

[0031] Its detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and the specific work is as follows.

[0032] First, the equipment achieves integrated detection of DC charging pile electrical parameters, charging gun temperature, appearance defects, and pile and wiring harness imaging through the coordinated operation of its various components. It also features flexible movement, leveling and fixing, and folding storage. The overall working principle is as follows: During the device transfer phase, the operator can hold the handle 51 and use the casters 11 at the bottom of the preparation box 10 to push the whole machine to the side of the DC charging pile to be tested. After arriving at the testing station, the operator can rotate the stabilizing screws 13 on the left and right stabilizing seats 12 in sequence. The screw drive will drive the pads 14 to extend downward and support the ground, lifting the whole machine. Combined with the stroke adjustment of the stabilizing screws 13, the preparation box 10 can be leveled on uneven ground, so that the equipment remains stable and avoids displacement or tilting during the testing process. The interior of the preparation box 10 is divided into cavity spaces by a partition 8. A battery 18 is installed below the partition 8 to provide power to all electrical components of the entire device. An integrated data board 19 is fixed above the partition 8 to collect, transmit, and store various types of test data. The controller body 17 is fixed above the embedded groove 54 on the front side wall of the preparation box 10, serving as the control center of the entire machine. It receives instructions from the operator and controls the start, stop, and operation of each mechanism. In the idle state, the seat frame 15 and the 90-degree flip-out support leg 16 are integrally embedded in the embedded groove 54, without occupying external space. During operation, the seat frame 15 and the support leg 16 can be flipped out and unfolded for the testing personnel to sit and rest. Sliding grooves 55 are opened at the bottom of the left and right side walls of the preparation box 10 to provide sliding guidance for the moving component 3. A storage groove 52 and a connected flip groove 53 are set at the top for storing and limiting the first testing structure 2. When conducting a special test on the charging gun, the flip arm tube 21 stored in the flip slot 53 and the storage slot 52 is rotated outward, causing the test boxes 22 at both ends to rotate out to the working position; one of the test boxes 22 connects to the charging gun of the charging pile through the docking gun head 23 in the side wall interface 62. The docking gun head 23 is electrically connected to the battery 18 and the integrated data board 19 respectively, and collects electrical parameters such as the output voltage and current of the charging pile in real time. The swing arm 24 in the L-shaped mounting slot 61 on the test box 22 is flipped out, so that the temperature detector 25 at the end of the swing arm 24 is attached to the surface of the charging gun to continuously detect the operating temperature of the charging gun. The temperature data is synchronously transmitted to the integrated data board 19. The other side of the detection box 22 is equipped with a cross-shaped electric slide rail 26. The cross-shaped electric slide rail 26 drives the L-shaped base 27 to complete the up and down and back and forth displacement adjustment. The LED light 28 at one end of the base 27 can be freely flipped to adjust the illumination angle to provide supplementary light to the charging gun interface. The first camera 29 at the other end of the base 27 completes multi-angle imaging in conjunction with the illumination, thereby detecting appearance defects such as wear, cracking, and deformation of the charging gun plug. The images and appearance inspection data are all imported into the integrated data board 19. During the testing process, the refurbishment box 10 is positioned opposite the charging pile. The hydraulic cylinder bodies 31, which are symmetrically arranged on the left and right sides of the battery 18 inside the refurbishment box 10, are activated. The hydraulic cylinder bodies 31 serve as the power source, driving the sliding arm 32 to perform linear extension and retraction along the sliding groove 55 of the refurbishment box 10. The outer end of the sliding arm 32 is connected to the first lifting slide rail 33, which is symmetrically arranged in opposite directions. The two first lifting slide rails 33 work together to drive the rear linkage frame 34 to complete the forward and backward movement and vertical lifting action simultaneously. After the linkage frame 34 moves backward and disengages from the storage box 41, it can drive the detection unit 43 in the second detection structure 4 to disengage from the storage box 41. The middle part is vertically fixed to the second lifting slide rail 35, further increasing the vertical adjustment stroke, thereby driving the entire rear second detection structure 4 to move to the corresponding detection area of ​​the charging pile. The second detection structure 4 relies on the concave storage boxes 41 symmetrically installed on the left and right sides of the rear side wall of the preparation box 10 to achieve storage and positioning. The storage box 41 has a storage opening 71 at the bottom. When the equipment is stored, the linkage frame 34 drives the mounting arm 42 and the detection unit 43 to be inserted into the storage opening 71 as a whole. During operation, the moving component 3 drives the mounting arm 42 to detach from the storage box 41. The mounting arm 42 rises and falls synchronously with the second lifting slide rail 35. The mounting arm 42 has a first reversing groove 72 at both ends for assembling the detection units 43 on both sides. When operating the detection unit 43, firstly, the first detection arm 431, which is embedded in the first reversing groove 72, is rotated 90 degrees outward to extend the detection length. Then, the first bolt 432 is tightened to tighten the limit and prevent the first detection arm 431 from loosening and rotating. Next, the second detection arm 433, which is embedded in the second reversing groove 73 at the end of the first detection arm 431, is rotated 90 degrees and extended to the rear of the equipment to widen the detection width. Finally, the second bolt 434 is tightened to complete the locking and fixing. The second camera 435 is equidistantly arranged on the mounting arm 42, the first detection arm 431, and the second detection arm 433. The position and shooting angle are adjusted synchronously with the arm body to collect images of the charging pile shell, external wiring harness, and wiring parts from all directions, and identify faults such as shell damage, wiring harness aging, loosening, and cracking. All image data are transmitted to the integrated data board 19 for aggregation and display on the controller body 17. During the power-on testing of this charging pile, the charging guns of adjacent charging piles can be connected for visual inspection. After the electrical data testing is completed, their positions can be swapped for further testing. After all testing procedures are completed, first loosen the second bolt 434 and the first bolt 432, and then flip and reset the second testing arm 433 and the first testing arm 431 in sequence, keeping them in a parallel and retracted state with their corresponding arms. Then, control the movement component 3 to move, the hydraulic cylinder body 31 drives the sliding arm 32 to retract, the first lifting slide rail 33 and the second lifting slide rail 35 to reset, and the linkage frame 34... The mounting arm 42 and the detection unit 43 are re-inserted into the storage opening 71 of the storage box 41, completing the overall storage of the second detection structure 4; then the flip arm tube 21 of the first detection structure 2 is rotated back, so that the detection box 22 is re-inserted into the storage slot 52 and flip slot 53 of the preparation box 10; finally, the stabilizing screw 13 is rotated in the opposite direction, causing the pad 14 to be retracted upwards, releasing the equipment from its fixed state, and the preparation box 10 is tilted towards the universal wheel 11 by holding the handle 51, so that the universal wheel 11 touches the ground, and the whole machine can be transferred to the next detection point.
