Description

Technical Field

[0001] The present invention relates to the technical field of new energy vehicles, and particularly to a charging detection device for new energy vehicles. Background Art

[0002] New energy vehicles refer to vehicles that use unconventional vehicle fuels as power sources and integrate advanced technologies in vehicle power control and drive, forming vehicles with advanced technical principles, new technologies, and new structures. Among them, electric vehicles are the most widely used new energy vehicles at present. During the use of electric vehicles, charging is often required. To ensure the charging quality, charging detection needs to be carried out regularly.

[0003] When charging detection is required, the charging head in the charging pile is inserted into the corresponding detection device to simulate the charging of new energy vehicles and perform corresponding detection operations. The operation is simple and the degree of intelligence is relatively high. In the actual detection process, the wire between the charging pile and the charging head is generally located inside the detection device. During detection, the temperature inside the detection device is adjusted to simulate the usage environment of the wire. However, in actual use, the charging head is inserted into the electric vehicle and is rarely affected by the external environment. Moreover, the internal space of the detection device is relatively large. During the simulation operation, the overall power consumption is relatively large, resulting in great waste. And it is only a simulation of the external environment. During the actual charging process, the natural wind will cause the wire to move, and during actual use, when the user holds the wire, it will also form a pressing operation on the wire. The traditional detection device does not simulate the above situations, and during detection, there is no detection of the connection stability between the wire and the charging head. Therefore, a charging detection device for new energy vehicles is provided. Summary of the Invention

During the electrical detection process, if an abnormality occurs, it may be that the connection effect between the wire and the charging head is poor. The electrical detection can be stopped for corresponding inspection, and thus the detection operation of the connection effect between the wire and the charging head can be completed.

Detailed implementation mode

[0034] Refer to Figures 1 - 15 , a charging detection device for a new energy vehicle, including a main body 1, a protective cover 2 is installed on the upper side of the main body 1, a lock sleeve is jointly installed on the outer sides of the protective cover 2 and the main body 1, and a handle is fixedly connected to the outer side of the main body 1;

[0035] Through the protective cover 2, when the main body 1 is not in use, the upper side of the main body 1 is protected. Through the lock sleeve, the protective cover 2 is fixedly installed on the upper side of the main body 1. This is the prior art and will not be elaborated further;

[0036] A protective plate 3 is clamped to the lower side of the main body 1. A slot 8 is opened in the main body 1. A clamping component is installed in the main body 1. The clamping component includes two clamping plates 34 fixedly installed on the upper side of the protective plate 3. A positioning plate 35 is slidably connected between the two clamping plates 34. A third threaded rod 36 is threadedly connected to the positioning plate 35, and the third threaded rod 36 rotatably penetrates through the protective plate 3;

[0037] First of all, the main body 1 is installed with the protective plate 3 by means of spring clamping. Secondly, a display screen, a control panel, an emergency stop switch, etc. are fixedly installed on the upper side of the main body 1. When it is necessary to perform charging detection on a new energy vehicle, the charging head of the charging pile is inserted into the slot 8, and then the main body 1 is used to simulate the charging of the new energy vehicle. During the charging process, the electrical variables are detected. The staff can view the display screen to know the actual detection results. And when an abnormality occurs, the detection can be stopped through the emergency stop switch to reduce accidents. And, a through groove is opened on the lower side of the main body 1. When it is necessary to perform charging detection, the protective plate 3 is taken out from the main body 1, and the wire connected to the charging head is passed through the through groove. Then, when performing the detection, the protective plate 3 is installed on the lower side of the main body 1 again. Then, rotate the third threaded rod 36. Since the positioning plate 35 is threadedly connected to the third threaded rod 36 and the positioning plate 35 is slidably connected to the clamping plate 34 up and down, the rotating third threaded rod 36 will drive the positioning plate 35 to move upward until the wire is fixedly clamped in the through groove. The above are all prior arts and will not be elaborated further;

[0038] Such as Figure 4 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 、 Figure 12A moving box 5 is slidably connected in the main body 1, and two moving plates 10 are slidably connected in the moving box 5. The upper sides of the two moving plates 10 are fixedly connected with fixed plates 23, and a third spring 21 is fixedly connected between the fixed plate 23 and the moving box 5. A simulator 11 is fixedly connected in the moving box 5. A first threaded rod 4 is rotatably connected in the main body 1. The thread of the moving box 5 passes through the first threaded rod 4. Two first racks 9 are symmetrically fixedly connected in the main body 1. Both sides of the moving box 5 are rotatably connected with a rotating shaft 16. The outer side of the rotating shaft 16 is fixedly connected with a first gear 14. The first gear 14 and the first rack 9 are meshed. Two transmission rods 13 are rotatably connected on both sides of the moving box 5. The outer sides of the two transmission rods 13 and the rotating shaft 16 are fixed. A second gear 15 is connected, and two adjacent second gears 15 are meshed with each other. Two rotating rods 24 are rotatably connected in the two moving plates 10, and the two rotating rods 24 are transmission-connected through the pulley assembly 18 and the transmission rod 13. The outer sides of the two rotating rods 24 are fixedly connected with a rotating cylinder 26, and the outer side of the rotating cylinder 26 is circumferentially fixedly connected with a plurality of contact plates 28. A moving assembly is installed in the moving box 5, and the moving assembly includes a cam 17 fixedly installed on the outer side of the rotating shaft 16. Square rods 12 are slidably connected on both sides of the moving box 5, and one end of the square rod 12 is fixedly connected with a square plate 19, and a second spring 20 is fixedly connected between the square plate 19 and the moving box 5, and the other end of the square rod 12 is fixedly connected with an inner arc plate 22;

[0039] First, the simulator 11 includes an intelligent regulator, a temperature sensor, a transmitter, etc. The simulator 11 is electrically connected to the display screen and the control panel on the upper side of the body 1 through a wire. When performing charging detection, the simulator 11 can be started through the control panel, and the temperature inside the mobile box 5 can be adjusted through the simulator 11, thereby simulating the temperature of the charging head and the wire in the actual use process when the charging head and the wire are in a harsh environment, thereby improving the accuracy of the electrical detection results. Secondly, the side wall of the mobile plate 10 is provided with an arc hole. Before starting the electrical detection operation, first move away from the other party. The movable plate 10 is moved in the direction of the movable plate 10, and the movable plate 10 drives the fixed plate 23 to move. The fixed plate 23 compresses the third spring 21, and then the wire is placed between the two movable plates 10, and the wire is located in the arc hole. The movable plate 10 is released. Under the action of the third spring 21, the two movable plates 10 are abutted against each other again. When the movable box 5 is closed, the wire and the contact plate 28 are abutted against each other. Then, when performing electrical detection, the first threaded rod 4 is rotated. Since the first threaded rod 4 and the movable box 5 are threadedly connected, and the movable box 5 and the body 1 are slidably connected, when the first threaded rod 4 is rotated, the movable box 5 is connected to the body 1 by a thread. Figure 6Based on the direction, it will cause the moving box 5 to move to the left. And since the first rack 9 and the body 1 are fixedly connected, the rotating shaft 16 and the first gear 14 that follow the movement of the moving box 5 move. Among them, the first gear 14 and the rotating shaft 16 on the right side of the moving box 5 rotate counterclockwise, and the first gear 14 and the rotating shaft 16 on the left side of the moving box 5 rotate clockwise. Taking the first gear 14 and the rotating shaft 16 on the right side of the moving box 5 as an example, the rotating shaft 16 will drive the transmission rod 13 to rotate clockwise through the second gear 15, and the transmission rod 13 drives the rotating rod 24 to rotate clockwise through the pulley assembly 18, thereby causing the wire to move relative to the moving box 5. During this process, the length of the wire located inside the moving box 5 is not very long, and it is only used to simulate the use environment inside the moving box 5. Compared with the traditional simulation method (the traditional simulation method means placing the entire wire completely inside the device and then simulating the environment inside the device, where the charging head and the wire are both in the simulated environment and the overall energy consumption is relatively large), it is more in line with the actual usage situation, that is, the charging head is inserted into the new energy vehicle, and generally a corresponding protection board 3 will be equipped at the charging position of the new energy vehicle. Therefore, the influence of the external environment on the charging head can be basically ignored, that is, the charging wire is more affected by the external environment, which is reasonable;

[0040] Moreover, during the above working process, when the rotating shaft 16 rotates, the rotating shaft 16 drives the cam 17 to rotate. Under the action of the second spring 20, the square plate 19 always abuts against the cam 17. Therefore, during the rotation of the cam 17, it will cause the square rod 12 to move back and forth relative to the moving box 5. The square rod 12 drives the inner arc plate 22 to move back and forth. The back-and-forth moving inner arc plate 22 abuts against the wire, causing the wire to swing relative to the moving box 5. Furthermore, during the charging process of the wire, the wire can be simulated to shake under the action of force in the external environment, thereby improving the simulation effect and further improving the accuracy of the detection result.

[0041] Such as Figure 12 、 Figure 14 , a pressing component is installed inside the moving box 5. The pressing component includes two reciprocating cylinders 27 fixedly installed on the outer side of the rotating cylinder 26. The two reciprocating cylinders 27 are symmetrically arranged on the upper and lower sides of a plurality of contact plates 28. The outer sides of the two reciprocating cylinders 27 are both threadedly connected with reciprocating sleeves 29. The outer side of the reciprocating sleeve 29 is fixedly connected with a sliding plate 30. The sliding plate 30 is slidably connected with the moving plate 10. The side wall of the sliding plate 30 is threadedly connected with a second threaded rod 31. The outer side of the second threaded rod 31 is rotatably connected with a limiting plate 32. The side wall of the limiting plate 32 is fixedly connected with a plurality of insertion rods 33. The plurality of insertion rods 33 slidably penetrate through the sliding plate 30;

[0042] First, during the process of the rotating rod 24 driving the rotating cylinder 26 to rotate, the rotating cylinder 26 drives the reciprocating cylinder 27 to rotate. Since the reciprocating cylinder 27 and the reciprocating sleeve 29 are threadedly connected, and the sliding plate 30 and the moving plate 10 are slidably connected up and down, during the rotation of the reciprocating cylinder 27, the reciprocating sleeve 29, the sliding plate 30, the second threaded rod 31, the limiting plate 32 and the inserting rod 33 will move up and down as a whole. The inserting rod 33 abuts against the wire, forming a squeezing effect on the wire. Thus, it can simulate the squeezing effect on the wire during the use of the wire. And before the electrical detection operation, the second threaded rod 31 can be rotated to adjust the positions of the limiting plate 32 and the inserting rod 33 relative to the sliding plate 30, thereby completing the adjustment operation of the acting force of the inserting rod 33 on the wire.

[0043] Such as Figure 5 , Figure 12 , a shaking component is installed in the main body 1. The shaking component includes a shaking plate 6 slidably installed above the protection plate 3. A plurality of first springs 7 are fixedly connected between the shaking plate 6 and the protection plate 3. A moving cylinder 25 is fixedly connected to the lower side of the lower reciprocating sleeve 29. The moving cylinder 25 abuts against the shaking plate 6;

[0044] First, one side of the shaking plate 6 is located below the connection between the wire and the charging head. During the up and down movement of the lower reciprocating sleeve 29, the reciprocating sleeve 29 drives the moving cylinder 25 to move up and down. Under the action of the first spring 7, the moving cylinder 25 abuts against the shaking plate 6. Therefore, the up and down moving moving cylinder 25 will cause the shaking plate 6 to move up and down. The shaking plate 6 abuts against the wire at the connection between the wire and the charging head, causing the wire and the charging head to move. During the electrical detection process, if an abnormality occurs, it may be that the connection effect between the wire and the charging head is poor. The electrical detection can be stopped and corresponding inspections can be carried out, thereby completing the detection operation of the connection effect between the wire and the charging head.

[0045] In the present invention, when charging detection of a new energy vehicle is required, the charging head of the charging pile is inserted into the slot 8, and then the main body 1 is used to simulate the charging of the new energy vehicle. During the charging process, the electrical variables are detected. The staff can view the display screen to know the actual detection result. And when an abnormality occurs, the detection can be stopped through the emergency stop switch to reduce accidents. Moreover, a through groove is opened on the lower side of the main body 1. When charging detection is required, the protection plate 3 is taken out from the main body 1, and the wire connected to the charging head is passed through the through groove. Then, when detecting, the protection plate 3 is installed on the lower side of the main body 1 again. Then, the third threaded rod 36 is rotated. Since the positioning plate 35 and the third threaded rod 36 are threadedly connected, and the positioning plate 35 and the clamping plate 34 are slidably connected up and down, the rotating third threaded rod 36 will drive the positioning plate 35 to move upward until the wire is fixedly clamped in the through groove. The above are all prior arts and will not be elaborated further;

[0046] When performing charging detection, the simulator 11 can be started through the control panel, and the temperature inside the moving box 5 can be adjusted through the simulator 11, so as to simulate the temperature of the charger head and the wire in the actual use process when the charger head and the wire are in a harsh environment, improving the accuracy of the electrical detection results. Secondly, an arc-shaped hole is opened on the side wall of the moving plate 10. Before starting the electrical detection operation, first move the moving plate 10 in a direction away from each other. The moving plate 10 drives the fixed plate 23 to move, and the fixed plate 23 compresses the third spring 21. Then, place the wire between the two moving plates 10 and make the wire located in the arc-shaped hole. Release the moving plate 10. Under the action of the third spring 21, the two moving plates 10 are in contact again. While closing the moving box 5, the wire abuts against the contact plate 28. Then, when performing electrical detection, rotate the first threaded rod 4. Since the first threaded rod 4 is threadedly connected to the moving box 5 and the moving box 5 is slidably connected to the main body 1, when rotating the first threaded rod 4, based on Figure 6 the direction of, the moving box 5 will move to the left. And since the first rack 9 is fixedly connected to the main body 1, the rotating shaft 16 and the first gear 14 that follow the movement of the moving box 5 move. Among them, the first gear 14 and the rotating shaft 16 on the right side of the moving box 5 rotate counterclockwise, and the first gear 14 and the rotating shaft 16 on the left side of the moving box 5 rotate clockwise. Taking the first gear 14 and the rotating shaft 16 on the right side of the moving box 5 as an example, the rotating shaft 16 will drive the transmission rod 13 to rotate clockwise through the second gear 15, and the transmission rod 13 drives the rotating rod 24 to rotate clockwise through the pulley assembly 18, thereby causing the wire to move relative to the moving box 5. During this process, the length of the wire located inside the moving box 5 is not very long, and only the use environment is simulated inside the moving box 5. Compared with the traditional simulation method (the traditional simulation method means that the whole wire is completely placed inside the device, and then the environment is simulated inside the device. The charger head and the wire are both in the simulated environment, and the overall energy consumption is relatively large), it is more in line with the actual use situation, that is, the charger head is inserted into the new energy vehicle, and a corresponding protection plate 3 is generally equipped at the charging position of the new energy vehicle. Therefore, the influence of the external environment on the charger head can be basically ignored, that is, the charging wire is more affected by the external environment, which is reasonable;

[0047] Moreover, during the above working process, when the rotating shaft 16 rotates, the rotating shaft 16 drives the cam 17 to rotate. Under the action of the second spring 20, the square plate 19 always abuts against the cam 17. Therefore, during the rotation of the cam 17, the square rod 12 will move back and forth relative to the moving box 5. The square rod 12 drives the inner arc plate 22 to move back and forth. The inner arc plate 22 that moves back and forth abuts against the wire, causing the wire to swing relative to the moving box 5. Thus, it can simulate the shaking of the wire under the action of force in the external environment during the charging process of the wire. Furthermore, while improving the simulation effect, it can further improve the accuracy of the detection result;

[0048] During the process of the rotating rod 24 driving the rotating cylinder 26 to rotate, the rotating cylinder 26 drives the reciprocating cylinder 27 to rotate. Since the reciprocating cylinder 27 and the reciprocating sleeve 29 are threadedly connected, and the sliding plate 30 and the moving plate 10 are connected in a vertically sliding manner, during the rotation of the reciprocating cylinder 27, the reciprocating sleeve 29, the sliding plate 30, the second threaded rod 31, the limiting plate 32 and the inserting rod 33 will move up and down as a whole. The inserting rod 33 abuts against the wire, forming an extrusion effect on the wire. Thus, it can simulate the extrusion effect on the wire during the use process of the wire. And before the electrical detection operation, the second threaded rod 31 can be rotated to adjust the positions of the limiting plate 32 and the inserting rod 33 relative to the sliding plate 30, thereby completing the adjustment operation of the acting force of the inserting rod 33 on the wire;

[0049] During the process of the lower reciprocating sleeve 29 moving the rod up and down, the reciprocating sleeve 29 drives the moving cylinder 25 to move up and down. Under the action of the first spring 7, the moving cylinder 25 abuts against the shaking plate 6. Therefore, the moving cylinder 25 that moves up and down will cause the shaking plate 6 to move up and down. The shaking plate 6 abuts against the wire at the connection between the wire and the charging head, causing the wire and the charging head to move. During the electrical detection process, if an abnormality occurs, it may be that the connection effect between the wire and the charging head is poor. The electrical detection can be stopped and corresponding inspections can be carried out, thereby completing the detection operation of the connection effect between the wire and the charging head.
