Description

Technical Field

[0001] This invention relates to the field of new energy vehicle technology, and in particular to a new energy vehicle charging detection device. Background Technology

[0002] New energy vehicles refer to vehicles that use unconventional vehicle fuels as a power source 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 currently the most widely used new energy vehicles. During the use of electric vehicles, they need to be charged frequently, and in order to ensure charging quality, charging tests need to be performed regularly.

[0003] When charging testing is required, the charging head from the charging pile is inserted into the corresponding testing device to simulate the charging of a new energy vehicle and perform the corresponding testing operations. The operation is simple and highly intelligent. In the actual testing process, the wires between the charging pile and the charging head are generally located inside the testing device. During testing, the internal temperature of the testing device is adjusted to simulate the usage environment of the wires. However, in actual use, the charging head is inserted into the electric vehicle and is minimally affected by the external environment. Furthermore, the internal space of the testing device is relatively large, resulting in high overall power consumption during simulation operations and significant waste. Moreover, it only simulates the external environment. During actual charging, natural wind can cause the wires to move, and in actual use, the user's grip on the wires can also cause pressure on them. Traditional testing devices do not simulate these situations and do not test the stability of the connection between the wires and the charging head. Therefore, a new energy vehicle charging testing device is provided. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a new energy vehicle charging detection device.

[0005] The present invention adopts the following technical solution:

[0006] A new energy vehicle charging testing device includes a main body, a protective plate snapped onto the lower side of the main body, a slot inside the main body, a clamping assembly installed inside the main body, a movable box slidably connected inside the main body, two movable plates slidably connected inside the movable box, a fixed plate fixedly connected to the upper side of each of the two movable plates, a third spring fixedly connected between the fixed plate and the movable box, a simulator fixedly connected inside the movable box, a first threaded rod rotatably connected inside the main body, the movable box threaded through the first threaded rod, and two first racks symmetrically fixedly connected inside the main body. Both sides of the movable box are rotatably connected to a rotating shaft. A first gear is fixedly connected to the outer side of the rotating shaft. The first gear meshes with a first rack. Both sides of the movable box are rotatably connected to two transmission rods. A second gear is fixedly connected to the outer side of the two transmission rods and the rotating shaft. Two adjacent second gears mesh with each other. Both movable plates are rotatably connected to two rotating rods. Both rotating rods are connected to the transmission rods via a pulley assembly. A rotating cylinder is fixedly connected to the outer side of both rotating rods. Multiple contact plates are fixedly connected to the outer circumferential side of the rotating cylinder. A movable component is installed inside the movable box.

[0007] Preferably, the moving component includes a cam fixedly mounted on the outside of the rotating shaft, square rods slidably connected to both sides of the moving box, a square plate fixedly connected to one end of the square rod, a second spring fixedly connected between the square plate and the moving box, and an inner arc plate fixedly connected to the other end of the square rod.

[0008] Preferably, a pressing assembly is installed inside the movable box. The pressing assembly includes two reciprocating cylinders fixedly installed on the outside of the rotating cylinder. The two reciprocating cylinders are symmetrically arranged on the upper and lower sides of multiple contact plates. A reciprocating sleeve is threaded to the outside of each of the two reciprocating cylinders. A slide plate is fixedly connected to the outside of the reciprocating sleeve. The slide plate and the movable plate are slidably connected. A second threaded rod is threaded to the side wall of the slide plate. A limit plate is rotatably connected to the outside of the second threaded rod. Multiple insertion rods are fixedly connected to the side wall of the limit plate. The multiple insertion rods slide through the slide plate.

[0009] Preferably, a swaying assembly is installed inside the body. The swaying assembly includes a swaying plate slidably mounted on the upper side of the protective plate. A plurality of first springs are fixedly connected between the swaying plate and the protective plate. A movable cylinder is fixedly connected to the lower side of the reciprocating sleeve, and the movable cylinder abuts against the swaying plate.

[0010] Preferably, the clamping assembly includes two clamping plates fixedly mounted on the upper side of the protective plate, a positioning plate slidably connected between the two clamping plates, and a third threaded rod internally threaded to the positioning plate, the third threaded rod rotatably passing through the protective plate.

[0011] Preferably, both the third threaded rod and the first threaded rod are fixedly connected to a protective rubber sleeve on their outer sides.

[0012] Preferably, a protective cover is installed on the upper side of the main body, and a locking sleeve is installed together with the protective cover and the outer side of the main body. A handle is fixedly connected to the outer side of the main body.

[0013] The beneficial effects of this invention are:

[0014] 1. First, before performing electrical testing, place the wires in the mobile box. With the help of the simulator, the use of the wires in harsh environments can be simulated. In this process, only the wires are simulated, which is more in line with the actual use. Moreover, the mobile box has a small overall space, and the simulation requires less energy.

[0015] 2. Furthermore, during the electrical testing process, the inner arc plate moves back and forth, causing the wire to swing relative to the moving box. This simulates the swaying of the wire under the force of the external environment during charging, which can improve the simulation effect and further improve the accuracy of the test results.

[0016] 3. Then, during the electrical testing process, the up-and-down moving plug comes into contact with the wire, which will squeeze the wire, thus simulating the squeezing effect on the wire during use;

[0017] 4. Finally, when the reciprocating sleeve moves up and down, the shaking plate and the wires at the connection point of the charging head will come into contact with each other, causing the wires and the charging head to move. If any abnormality occurs during the electrical test, it may be due to a poor connection between the wires and the charging head. The electrical test can be stopped and the corresponding inspection can be carried out to complete the test of the connection between the wires and the charging head. Attached Figure Description

[0034] See Figures 1-15 A new energy vehicle charging detection device includes a body 1, a protective cover 2 installed on the upper side of the body 1, a locking sleeve installed on both the protective cover 2 and the outer side of the body 1, and a handle fixedly connected to the outer side of the body 1.

[0035] The protective cover 2 protects the upper side of the main body 1 when it is not in use. The protective cover 2 is fixedly installed on the upper side of the main body 1 by the locking sleeve. This is existing technology and will not be described in detail.

[0036] A protective plate 3 is snapped onto the lower side of the main body 1. A slot 8 is opened inside the main body 1. A clamping assembly is installed inside the main body 1. The clamping assembly 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 inside the positioning plate 35. The third threaded rod 36 rotates through the protective plate 3.

[0037] First, the protective plate 3 is installed on the main body 1 by spring snap-fit. Second, the upper side of the main body 1 is fixedly installed with a display screen, control panel, emergency stop switch, etc. When it is necessary to test the charging of 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, and the staff can watch the display screen to know the actual test results. When an abnormality occurs, the test can be stopped by the emergency stop switch to reduce the occurrence of accidents. In addition, the lower side of the main body 1 has a through slot. When it is necessary to test the charging, 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 slot. Then, when testing, the protective 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, the rotating third threaded rod 36 will drive the positioning plate 35 to move upward until the wire is fixedly clamped in the through slot. The above are all existing technologies and will not be described in detail.

[0038] like Figure 4 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12A movable box 5 is slidably connected inside the main body 1. Two movable plates 10 are slidably connected inside the movable box 5. A fixed plate 23 is fixedly connected to the upper side of each of the two movable plates 10. A third spring 21 is fixedly connected between the fixed plate 23 and the movable box 5. A simulator 11 is fixedly connected inside the movable box 5. A first threaded rod 4 is rotatably connected inside the main body 1. The movable box 5 is threaded through the first threaded rod 4. Two first racks 9 are symmetrically fixedly connected inside the main body 1. Rotating shafts 16 are rotatably connected to both sides of the movable box 5. A first gear 14 is fixedly connected to the outer side of the rotating shaft 16. The first gear 14 meshes with the first rack 9. Two transmission rods 13 are rotatably connected to both sides of the movable box 5. The outer sides of the two transmission rods 13 and the rotating shafts 16 are fixedly connected. A second gear 15 is connected, and two adjacent second gears 15 mesh with each other. Two rotating rods 24 are rotatably connected inside each of the two moving plates 10. The two rotating rods 24 are connected to the transmission rod 13 through the pulley assembly 18. A rotating cylinder 26 is fixedly connected to the outside of each of the two rotating rods 24. Multiple contact plates 28 are fixedly connected to the circumferential side of the rotating cylinder 26. A moving assembly is installed inside the moving box 5. The moving assembly includes a cam 17 fixedly installed on the outside of the rotating shaft 16. Square rods 12 are slidably connected to both sides of the moving box 5. A square plate 19 is fixedly connected to one end of the square rod 12. A second spring 20 is fixedly connected between the square plate 19 and the moving box 5. An inner arc plate 22 is fixedly connected to the other end of the square rod 12.

[0039] First, the simulator 11 includes an intelligent regulator, a temperature sensor, and a transmitter. The simulator 11 is electrically connected to the display screen and control panel on the upper side of the main body 1 via wires. During charging testing, the simulator 11 can be started via the control panel, and the temperature inside the moving box 5 can be adjusted using the simulator 11. This simulates the temperature of the charging head and wires in harsh environments during actual use, improving the accuracy of the electrical testing results. Second, the side wall of the moving plate 10 has arc-shaped holes. Before starting the electrical testing operation, the holes are moved away from the target device. The movable plate 10 is moved in the direction of the fixed plate 23, which in turn compresses the third spring 21. The wire is then placed between the two movable plates 10 and positioned within the arc-shaped hole. The movable plates 10 are released, and under the action of the third spring 21, the two movable plates 10 abut against each other again, closing the movable box 5. Simultaneously, the wire abuts against the contact plate 28. Then, during electrical testing, 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 main body 1 are slidably connected, rotating the first threaded rod 4... Figure 6Based on the direction, the moving box 5 will move to the left. Since the first rack 9 and the main body 1 are fixedly connected, the rotating shaft 16 and the first gear 14, which move with the moving box 5, will also move. Specifically, the first gear 14 and the rotating shaft 16 on the right side of the moving box 5 will rotate counterclockwise, while the first gear 14 and the rotating shaft 16 on the left side of the moving box 5 will 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 via the second gear 15. The transmission rod 13 will drive the rotating rod 24 to rotate clockwise via the pulley assembly 18, thereby causing the wire to move relative to the moving box 5. During the movement, the length of the wire inside the moving box 5 is not very long, and the simulation of the usage environment is only carried out inside the moving box 5. Compared with the traditional simulation method (the traditional simulation method refers to placing the entire wire inside the device and then simulating the environment inside the device, where both the charging head and the wire are 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 plugged into the new energy vehicle, and the charging position of the new energy vehicle is generally equipped with a corresponding protection board 3. Therefore, the influence of the external environment on the charging head can be ignored. That is, the charging cable is more affected by the external environment, which is reasonable.

[0040] Furthermore, during the aforementioned working process, when the rotating shaft 16 rotates, it drives the cam 17 to rotate. Under the action of the second spring 20, the square plate 19 is always in contact with 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 moving inner arc plate 22 is in contact with the wire, causing the wire to swing relative to the moving box 5. This can simulate the wire shaking under the force of the external environment during the charging process, thereby improving the simulation effect and further improving the accuracy of the detection results.

[0041] like Figure 12 , Figure 14 The movable box 5 is equipped with a pressing assembly, which includes two reciprocating cylinders 27 fixedly installed on the outside of the rotating cylinder 26. The two reciprocating cylinders 27 are symmetrically arranged on the upper and lower sides of multiple contact plates 28. The outer sides of the two reciprocating cylinders 27 are threadedly connected to reciprocating sleeves 29. The outer sides of the reciprocating sleeves 29 are fixedly connected to a slide plate 30. The slide plate 30 and the movable plate 10 are slidably connected. The side wall of the slide plate 30 is threadedly connected to a second threaded rod 31. The outer side of the second threaded rod 31 is rotatably connected to a limit plate 32. The side wall of the limit plate 32 is fixedly connected to multiple insert rods 33. The multiple insert rods 33 slide through the slide plate 30.

[0042] First, during the rotation of the rotating cylinder 26 driven by the rotating rod 24, 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, the rotation of the reciprocating cylinder 27 will cause the reciprocating sleeve 29, the sliding plate 30, the second threaded rod 31, the limiting plate 32, and the insertion rod 33 to move up and down as a whole. The insertion rod 33 abuts against the wire, which will create a squeezing effect on the wire. This can simulate the squeezing effect on the wire during use. Before the electrical testing operation, the second threaded rod 31 can be rotated to adjust the position of the limiting plate 32 and the insertion rod 33 relative to the sliding plate 30, thereby completing the adjustment operation of the force exerted by the insertion rod 33 on the wire.

[0043] like Figure 5 , Figure 12 The main body 1 is equipped with a shaking component, which includes a shaking plate 6 that is slidably mounted on the upper side of the protective plate 3. Multiple first springs 7 are fixedly connected between the shaking plate 6 and the protective plate 3. A movable cylinder 25 is fixedly connected to the lower side of the lower reciprocating sleeve 29. The movable 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 reciprocating sleeve 29 on the lower side, 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 and the shaking plate 6 abut against each other. Therefore, the up-and-down movement of the moving cylinder 25 will cause the shaking plate 6 to move up and down. The shaking plate 6 and the wire at the connection between the wire and the charging head abut against each other, which will cause the wire and the charging head to move. If an abnormality occurs during the electrical test, it may be that the connection between the wire and the charging head is poor. The electrical test can be stopped and the corresponding inspection can be carried out. In this way, the test operation of the connection effect between the wire and the charging head can be completed.

[0045] In this invention, when charging tests are required for new energy vehicles, 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, electrical variables are detected, and the staff can view the display screen to know the actual test results. In case of an abnormality, the test can be stopped by the emergency stop switch to reduce the occurrence of accidents. Furthermore, a through slot is opened on the lower side of the main body 1. When charging tests are 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 slot. Then, when testing, 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, the rotating third threaded rod 36 will drive the positioning plate 35 to move upward until the wire is fixedly clamped in the through slot. The above are all existing technologies and will not be described in detail.

[0046] During charging testing, the simulator 11 can be started via the control panel, and the internal temperature of the moving box 5 can be adjusted through the simulator 11 to simulate the temperature of the charging head and wires in harsh environments during actual use, thereby improving the accuracy of the electrical testing results. Secondly, the side wall of the moving plate 10 has an arc-shaped hole. Before starting the electrical testing operation, the moving plate 10 is moved away from the other side. The moving plate 10 drives the fixed plate 23 to move, and the fixed plate 23 compresses the third spring 21. Then, the wire is placed between the two moving plates 10, and the wire is positioned within the arc-shaped hole. The moving plate 10 is released, and under the action of the third spring 21, the two moving plates 10 abut against each other again, closing the moving box 5. At the same time, the wire abuts against the contact plate 28. Then, during electrical testing, the first threaded rod 4 is rotated. Since the first threaded rod 4 and the moving box 5 are threadedly connected, and the moving box 5 and the main body 1 are slidably connected, rotating the first threaded rod 4... Figure 6 Based on the direction, the moving box 5 will move to the left. Since the first rack 9 and the main body 1 are fixedly connected, the rotating shaft 16 and the first gear 14, which move with the moving box 5, will also move. Specifically, the first gear 14 and the rotating shaft 16 on the right side of the moving box 5 will rotate counterclockwise, while the first gear 14 and the rotating shaft 16 on the left side of the moving box 5 will 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 via the second gear 15. The transmission rod 13 will drive the rotating rod 24 to rotate clockwise via the pulley assembly 18, thereby causing the wire to move relative to the moving box 5. During the movement, the length of the wire inside the moving box 5 is not very long, and the simulation of the usage environment is only carried out inside the moving box 5. Compared with the traditional simulation method (the traditional simulation method refers to placing the entire wire inside the device and then simulating the environment inside the device, where both the charging head and the wire are 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 plugged into the new energy vehicle, and the charging position of the new energy vehicle is generally equipped with a corresponding protection board 3. Therefore, the influence of the external environment on the charging head can be ignored. That is, the charging cable is more affected by the external environment, which is reasonable.

[0047] Furthermore, during the aforementioned working process, when the rotating shaft 16 rotates, it drives the cam 17 to rotate. Under the action of the second spring 20, the square plate 19 is always in contact with 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 moving inner arc plate 22 is in contact with the wire, causing the wire to swing relative to the moving box 5. This can simulate the wire shaking under the force of the external environment during the charging process, thereby improving the simulation effect and further improving the accuracy of the detection results.

[0048] During the rotation of the rotating cylinder 26 driven by the rotating rod 24, 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, the rotation of the reciprocating cylinder 27 will cause the reciprocating sleeve 29, the sliding plate 30, the second threaded rod 31, the limiting plate 32 and the insertion rod 33 to move up and down as a whole. The insertion rod 33 abuts against the wire, which will create a squeezing effect on the wire. This can simulate the squeezing effect on the wire during use. Before the electrical testing operation, the second threaded rod 31 can be rotated to adjust the position of the limiting plate 32 and the insertion rod 33 relative to the sliding plate 30, thereby completing the adjustment operation of the force exerted by the insertion rod 33 on the wire.

[0049] During the up-and-down movement of the reciprocating sleeve 29 on the lower side, 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 and the shaking plate 6 abut against each other. Therefore, the up-and-down movement of the moving cylinder 25 will cause the shaking plate 6 to move up and down. The shaking plate 6 and the wire at the connection between the wire and the charging head abut against each other, which will cause the wire and the charging head to move. If an abnormality occurs during the electrical test, it may be that the connection between the wire and the charging head is poor. The electrical test can be stopped and the corresponding inspection can be carried out to complete the test of the connection between the wire and the charging head.
