Description

Technical Field

[0001] The present invention belongs to the technical field of charging pile testing, and in particular, relates to a portable automobile charging pile detection device. Background Art

[0002] The development of electric vehicle technology has driven a sharp increase in the number of charging piles worldwide. However, due to the wide distribution of charging piles and different environmental conditions, their maintenance and management are challenging. Traditional fixed detection equipment is often bulky and inconvenient to move, while portable car charging pile detection devices solve this problem. In addition, charging piles produced by different manufacturers may have compatibility issues, which not only affects the user experience, but may also cause safety hazards. Therefore, regular inspection and maintenance of charging piles is particularly important.

[0003] After searching, the invention with application publication number CN116430076A discloses a portable detection device for charging pile testing, which also includes a box body, a winding mechanism and a heat dissipation mechanism.

The detection body is located at the bottom of the mounting groove, the winding mechanism is located on the right side of the box body, and the cable is stored through the winding mechanism. The heat dissipation mechanism is located in the mounting groove. The detection device has some shortcomings when detecting the performance and safety of the charging pile. Although it is a portable device, considering that it includes components such as a box body, a winding mechanism and a heat dissipation mechanism, the volume and weight of the entire device are still not small, and there is a lack of storage and assembly and disassembly structure design, which is inconvenient to load into a carrier for use. It needs to be carried as a whole when used, which is inconvenient for operators to carry, especially in large parking lots or charging stations, affecting the flexibility and efficiency of the detection work; and because the device is a single-channel design, only a single charging pile can be tested for parameters at a time, resulting in low efficiency of the detection work.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] Embodiment 1: A portable vehicle charging pile detection device, such as Figure 1-Figure 4As shown, it includes a charging column detector 1, which is a prior art detection equipment for automobile charging piles. Communication interfaces 2 and digital display screens 3 are symmetrically integrated on both sides of the charging column detector 1. The communication interface 2 is used to connect the charging line of the detection charging pile, and the digital display screen 3 is used to display the detection parameters of the charging pile; it also includes a connection block 4 symmetrically fixed to the outer walls of both sides of the lower part of the shell of the charging column detector 1, and support plates 5 are hinged on the connection blocks 4. The support plates 5 are used to conveniently support the entire charging column detector 1 on a detection vehicle or other vehicle, and the support plates 5 are away from the charging The plate end of the charging column detector 1 is provided with a suction cup 6, which is used to be adsorbed on the body of the carrier vehicle. A tension spring 52 is provided between the support plate 5 and the outer shell of the charging column detector 1. A connecting block 2 41 is fixedly connected to the outer walls on both sides of the middle part of the outer shell of the charging column detector 1. The connecting block 2 41 is hinged with a hinged rod 1 7. The rod end of the hinged rod 1 7 is hinged with a hinged rod 2 71. A limit block for limiting the rotation angle is fixed at the hinge of the hinged rod 1 7 and the hinged rod 2 71. A guide groove 51 is provided in the middle of the support plate 5. The hinged rod 2 71 is away from the rod end of the hinged rod 1 7 and the support plate 5. The guide groove 51 is slidably connected to overcome the elastic force of the tension spring 52 to rotate the support plate 5 from both sides of the charging column detector 1 shell to open. After the hinge rod 1 7 and the hinge rod 2 71 rotate to a certain support angle, they will be limited by the limit block. With the pulling force of the tension spring 52, the hinge rod 1 7 and the hinge rod 2 71 can form a stable support structure for the support plate 5, and cooperate with the suction cup 6 on the support plate 5 to be adsorbed on the vehicle body, so that the charging column detector 1 can be conveniently assembled on the vehicle of the detection personnel for use, thereby facilitating the transportation of the entire detection device to the vicinity of the charging pile. During the detection, the two-way communication interface 2 on the charging column detector 1 is connected, so that the two charging piles can be efficiently detected simultaneously. After the detection is completed, the support plate 5 on the charging column detector 1 can be stored, so as to facilitate the movement of the entire detection device. A docking plate 8 is provided at the bottom of the outer wall of the charging column detector 1. The bottom of the docking plate 8 of the charging column detector 1 is detachably equipped with a support component 9. The support component 9 is used to place the detection device on the ground to detect the charging pile, so that the detection device can be flexibly used under conditions where it is inconvenient to use a vehicle.

[0029] like Figure 4-Figure 6As shown, the docking plate 8 is rotatably mounted on the bottom of the housing of the charging column detector 1. Two guide rails 81 are fixedly arranged on the bottom surface of the docking plate 8. A notch is provided on the guide rail 81. A positioning block 82 is fixedly installed at the notch of the guide rail 81 on the bottom surface of the docking plate 8. The two ends of the positioning block 82 are symmetrical wedge blocks. The positioning block 82 is elastic. A docking groove 911 is provided on the top surface of the docking plate 91. A bayonet adapted to the positioning block 82 is provided on the inner wall of the docking groove 911 of the docking plate 91. The docking plate 91 is aligned with the guide rail 81 of the docking plate 8 through the docking groove 911 and then slides to the docking plate 91. The docking plate 91 is pressed against the wedge-shaped block of the positioning card block 82, causing the positioning card block 82 to be compressed and deformed inwardly until the snap-in of the docking slide groove 911 of the docking plate 91 is aligned with the wedge-shaped block of the positioning card block 82, and the wedge-shaped block of the positioning card block 82 pops outward and snaps into the snap-in of the docking plate 91. Similarly, after continuing to push the docking plate 91 forward, the snap-in of the docking slide groove 911 of the docking plate 91 is disengaged from the snap of the positioning card block 82 to complete the release, thereby achieving convenient snap-in and release of the docking plate 8 and the docking plate 91, and realizing the quick disassembly and assembly of the charging column detector 1 and the support assembly 9.

[0030] like Figure 4 and Figure 5 As shown, the top surface of the docking plate 8 is slidably assembled with a card ball 83 through a groove, and a compression spring 84 is provided between the card ball 83 and the docking plate 8. A plurality of card slots 831 adapted to the card ball 83 are circumferentially opened on the bottom surface of the outer shell of the charging column detector 1. The card ball 83 is inserted into the corresponding card slot 831 at the bottom of the outer shell of the charging column detector 1 under the action of the spring, so that when the charging column detector 1 is rotated on the docking plate 8 to adjust the detection angle, the additional resistance to the rotation of the charging column detector 1 is increased, so as to prevent the charging column detector 1 from accidentally moving due to slight external force when detecting the charging pile, thereby improving the stability and safety of the charging column detector 1.

[0031] When it is necessary to inspect the car charging pile, the device can be used. When the inspection conditions of the charging pile meet the conditions for using a carrier vehicle, the inspector first assembles the charging column detector 1 and the carrier vehicle for use. During operation, the inspector first places the charging column detector 1 on the carrier vehicle, and then unfolds the support plate 5 outward from both sides of the charging column detector 1. The support plate 5 overcomes the elastic force of the tension spring 52 and uses the linkage structure of the hinge rod 1 7 and the hinge rod 2 71 to rotate the support plate 5 to the maximum rotation limit angle of the hinge rod 1 7 and the hinge rod 2 71. At this time, the tension of the tension spring 52 and the triangular support structure formed by the hinge rod work together to keep the support plates 5 on both sides of the charging column detector 1 in a stable unfolded state, and then the suction cups 6 at the ends of the support plates 5 are Press and adsorb it on the surface of the car body, and use vacuum adsorption to temporarily fix the charging column detector 1 on the smooth surface of the car body. After the charging column detector 1 is fixed to the carrier vehicle, the detection device is transported to the vicinity of the charging pile to be detected by the carrier for detection. During the detection, the charging lines of the two charging piles can be respectively connected to the communication interfaces 2 on both sides of the charging column detector 1. The voltage, current, communication protocol and other detection parameters can be displayed in real time through the digital display screen 3. During the detection process, if the detector angle of the charging column detector 1 needs to be adjusted, the charging column detector 1 can be manually rotated. At this time, the card ball 83 on the docking plate 8 is embedded in different card slots 831 at the bottom of the charging column detector 1 under the action of the compression spring 84, providing positioning resistance to prevent accidental touch and deviation, thereby improving the stability of the detection device when detecting the charging pile.

[0032] Embodiment 2: Based on embodiment 1, Figure 1 , Figure 6 and Figure 7 As shown, the support assembly 9 includes a docking plate 91, an outer tube 92 is fixedly installed at the bottom of the docking plate 91, a first telescopic tube 921 is slidably connected to the inner wall of the outer tube 92, a second telescopic tube 922 is slidably connected to the inner wall of the first telescopic tube 921, a third telescopic tube 923 is slidably connected to the inner wall of the second telescopic tube 922, and a driving member is provided inside the outer tube 92, the driving member is used to multi-stage drive the first telescopic tube 921, the second telescopic tube 922 and the third telescopic tube 923, so that the first telescopic tube 921, the second telescopic tube 922 and the third telescopic tube 923 form a multi-stage telescopic support structure in the outer tube 92, so that the charging column detector 1 docked on the support assembly 9 can be lifted and adapted to charging piles of different heights for detection, and a handle 95 is fixedly provided on the outer wall of the outer tube 92.

[0033] like Figure 6 and Figure 7As shown, the driving member includes a servo motor 93 fixedly mounted on the bottom surface of the docking plate 91, and a first screw 941 is fixedly connected to the output shaft of the servo motor 93. The first screw 941 and the first telescopic tube 921 are threadedly matched, and the outer wall of the rod body of the first screw 941 is threadedly embedded with a second screw 942, and the second screw 942 and the second telescopic tube 922 are threadedly matched. The outer wall of the rod body of the second screw 942 is threadedly embedded with a third screw 943, and the third screw 943 and the third telescopic tube 923 are threadedly matched. The servo motor 93 drives the first screw 941, the second screw 942 and the third screw 943 to rotate synchronously, thereby correspondingly threading and driving the first telescopic tube 921, the second telescopic tube 922 and the third telescopic tube 923, respectively, so that relative movement is generated between adjacent telescopic tubes, and the effect of multi-stage telescopic support is achieved.

[0034] like Figure 1 , Figure 6 and Figure 8 As shown, a spreading component 10 is provided at the bottom of the support component 9, and the spreading component 10 includes a chassis 101 fixedly mounted on the third telescopic tube 923, and a plurality of reinforcing plates 102 are hingedly connected to the middle part of the chassis 101 at circumferential intervals, and the reinforcing plates 102 are used to rotate and spread on the disk surface of the chassis 101, thereby improving the supporting stability of the chassis 101 on the bottom surface, and a rotating ring 103 is rotatably connected to the middle part of the chassis 101, and the outer wall of the rotating ring 103 is circumferentially fixed with snap blocks 104 with the same number as the reinforcement plates 102, and the snap blocks 104 are used to snap and limit the reinforcement plates 102 that are rotated and spread on the chassis 101, and the reinforcement plates 102 can also be stored around the outer wall of the third telescopic tube 923 under the limit of the snap blocks 104.

[0035] When the detection conditions of the charging pile do not meet the conditions for using the carrier vehicle, the support plate 5 is rotated and reset to be stored in the charging column detector 1, and then the chassis 101 is placed on the ground near the charging pile, and then the support assembly 9 is connected to the bottom of the charging column detector 1 through the docking plate 8. During operation, the docking groove 911 of the docking plate 91 is aligned with the guide rail 81 and slid into the docking plate 91. The wedge block of the positioning block 82 is compressed and deformed and then snapped into the bayonet of the docking plate 91, thereby completing the quick locking. At this time, the servo motor 93 drives the first screw 941, the second screw 942 and the third screw 943 to rotate synchronously, and the first telescopic tube 921, the second telescopic tube 922 and the third telescopic tube 92 are extended step by step. 3 is extended and retracted to lift the detector to a height matching the charging pile interface, and then the expansion component 10 at the bottom of the outer tube 92 is used to reinforce the entire detection device, and the buckle block 104 is driven to rotate by the rotating ring 103, so that the buckle block 104 on the rotating ring 103 releases the corresponding reinforcement plate 102, and then the reinforcement plate 102 is released and unfolded to the periphery of the chassis 101, and then the rotating ring 103 is rotated in the opposite direction to make the buckle block 104 buckle the expanded reinforcement plate 102 again, thereby increasing the support area of ​​the chassis 101 to improve the stability of the detection device, thereby the entire detection device can also be supported on the ground to detect the charging pile, and the detection flexibility of the device for the charging pile is improved.

[0036] like Figure 1 , Figure 3 and Fig. 9 As shown, a guide frame 11 and a fan 12 are also included. Ventilation holes are opened on both sides of the outer shell of the charging post detector 1. The guide frame 11 is installed at one of the vents of the outer shell of the charging post detector 1. The vent of the guide frame 11 faces downward and is used for exhausting air. A plurality of fans 12 are installed at another vent of the outer shell of the charging post detector 1. The fans 12 are used to dissipate heat to the electrical components in the charging post detector 1 and discharge the heat dissipation airflow through the guide frame 11, thereby increasing the service life of the charging post detector 1.

[0037] like Fig. 9 As shown, a refrigerator 13 is provided at the bottom of the outer shell of the charging pole detector 1, and a mounting frame 131 is fixedly provided in the outer shell of the charging pole detector 1 near the fan 12. A cooling pipe 132 is provided in the mounting frame 131. Cooling liquid is added inside the cooling pipe 132. The inlet and outlet of the cooling pipe 132 are respectively connected to the inlet of the compressor of the refrigerator 13 and the outlet of the evaporator. The refrigerator 13 is used for circulating cooling the coolant in the cooling pipe 132, so that the fan 12 cooperates with the cooling pipe 132 to improve the heat dissipation efficiency of the internal electrical components of the charging pole detector 1.

[0038] When the detector is running for a long time, the fan 12 is enabled. The fan 12 blows air into the detector from the vent on one side of the charging column 1. The air flows through the cooling pipe 132 (internal circulating refrigerant) in the mounting frame 131, cools down, and then blows to the internal electrical components of the charging column 1 for forced heat dissipation. The coolant in the cooling pipe 132 is then continuously exchanged with the compressor through the evaporator of the refrigerator 13. The airflow with the heat removed is discharged from the vent on the other side through the guide frame 11, thereby forming a directional heat dissipation channel to prevent hot air reflux from affecting the detection accuracy of the charging column detector 1 and to improve its service life. If the detection environment space of the charging pile is limited, the telescopic tube can be driven in reverse by the servo motor 93 to retract step by step to lower the height of the detector, while keeping the reinforcement plate 102 in the expanded state to maintain the support stability. After the detection is completed, the charging cable on the charging pile is disconnected first. For the vehicle-mounted detection mode, the suction cup 6 can be pressed to release the adsorption of the vehicle, and then the support plate 5 can be folded inward to break the hinged rod. 7 and the support structure between the hinged rod 71, so that the hinged rod 71 slides along the guide groove 51, and the tension spring 52 contracts to make the support plate 5 close to the detector housing to complete the storage; for the ground detection mode, first retract the expanded reinforcement plate 102 onto the chassis 101, and then enable the servo motor 93 to drive the first screw 941, the second screw 942 and the third screw 943 to rotate in the opposite direction, drive the first telescopic tube 921, the second telescopic tube 922 and the third telescopic tube 923 to retract completely, rotate the rotating ring 103 to disengage the buckle block 104 from the reinforcement plate 102, store it around the chassis 101 to fit the outer tube 92 and reduce the occupied space, and then rotate the docking plate 91 to disengage the bayonet from the positioning block 82, lift the charging column detector 1 upwards to complete the separation from the support assembly 9, and the separated charging column detector 1 and the support assembly 9 can be transferred separately, so as to realize the rapid disassembly and assembly and flexible adaptation of the entire detection device, and significantly improve the detection efficiency and the portability of the equipment.
