Description

Technical Field

[0001] The present application relates to the technical field of charging pile testing, and in particular to a stable interface structure for charging pile aging testing. Background Art

[0002] A charging pile is a device that provides electric energy for electric vehicles. It can convert AC or DC power into the voltage and current required by electric vehicles to achieve charging. During the development of charging piles, it is necessary to conduct aging tests on the charging piles to expose the performance defects of the charging pile products and improve them.

[0003] At present, charging pile aging tests mostly rely on repeated plug-in and pull-out experiments simulating real usage conditions to evaluate their durability. Common methods include but are not limited to: manual plug-in test method, which is simple and easy but inefficient and prone to human errors; automated plug-in equipment, which improves test efficiency but has high equipment and maintenance costs, and poor compatibility with complex interfaces; environmental stress screening (ESS) test, which accelerates the aging process of charging piles through environmental factors such as high temperature, low temperature, and humidity changes. This method can effectively identify potential design defects, but it is extremely demanding on the test environment and has a long cycle.

Automated plug-in and unplug equipment is expensive and has a limited scope of application. Environmental stress screening test conditions are harsh and difficult to popularize. In addition, the common problem of these methods is the lack of accurate measurement methods for the time-varying characteristics of the electrical contact quality inside the charging pile, which leads to incomplete and unreliable test results.

[0032] The driving module 2 includes a base 21, a first movable member 22, a second movable member 23, a third movable member 24, a first driving member 25, a second driving member 26 and a third driving member 27. The base 21 is used for installing and positioning other components of the driving module 2 and for placing the charging pile 5; the first movable member 22, the second movable member 23 and the third movable member 24 jointly control the position of the interface module 3, so as to facilitate the plugging and unplugging of the interface module 3 and the charging pile 5; the first driving member 25, the second driving member 26 and the third driving member 27 provide power to the first movable member 22, the second movable member 23 and the third movable member 24 respectively.

[0033] The base 21 is a rectangular plate-shaped structure as a whole. The base 21 is installed and fixed in a vertical state in the thickness direction. One end of the top length direction has a placement area 211 for placing and positioning the charging pile 5, and the coverage of the placement area 211 is larger than the floor area of ​​the charging pile 5. In this embodiment, the charging pile 5 is preferably a rectangular parallelepiped structure as a whole, and the socket of the charging pile 5 is preferably located on one side of the length direction thereof; since the charging pile 5 is a prior art in the art, it will not be described in detail here, and it is only briefly shown in the drawings.

[0034] The first movable member 22 is movably mounted at one end of the top of the base 21 away from the placement area 211, and the moving direction of the first movable member 22 is parallel to the width direction of the base 21; the first driving member 25 is fixedly mounted on one side of the width direction of the base 21, and can control the movement of the first movable member 22 relative to the base 21. In this embodiment, the first driving member 25 is preferably a servo motor, and the first driving member 25 preferably controls the movement of the first movable member 22 by means of a screw drive; since the servo motor and the screw drive are both common existing technologies, they are not described here in detail, and they are only briefly shown in the drawings.

[0035] The second movable member 23 is movably mounted on a side of the first movable member 22 close to the placement area 211, and the moving direction of the second movable member 23 is parallel to the thickness direction of the base 21; the second driving member 26 is fixedly mounted on the top of the first movable member 22, and can control the movement of the second movable member 23 relative to the first movable member 22. In this embodiment, the second driving member 26 is preferably also a servo motor, and the second driving member 26 is preferably also used to control the movement of the second movable member 23 by screw transmission.

[0036] The third movable member 24 is mounted on a side of the second movable member 23 close to the placement area 211, and can move relative to the second movable member 23, and its movement direction is parallel to the length direction of the base 21; the third driving member 27 is fixedly mounted on the second movable member 23, located on a side of the second movable member 23 away from the placement area 211, and can control the movement of the third movable member 24 relative to the second movable member 23. In this embodiment, the third driving member 27 is preferably a servo cylinder, and the third driving member 27 preferably controls the movement of the third movable member 24 by controlling a point of the piston rod.

[0037] Reference Figure 3 and Figure 4 The interface module 3 is installed at one end of the third movable part 24 close to the placement area 211, and includes a housing 31, a rotating disk 32, a plurality of interfaces 34 and a fourth driving member 33. The housing 31 is used to provide protection for some parts of the interface module 3; the rotating disk 32 is used for installing the interface 34, and it is convenient for the interface module 3 to select a suitable interface 34 according to different types of charging piles 5; the interface 34 is used to plug and match with the charging pile 5 to form a circuit connection; the fourth driving member 33 is used to provide power to the rotating disk 32, so that the rotating disk 32 can rotate and switch the interface 34.

[0038] The shell 31 is fixedly connected to one end of the third movable part 24 near the placement area 211. The interior of the shell 31 has a cavity 311 that provides space for the rotating disk 32 and multiple interfaces 34. The cavity 311 has an opening 312 formed at the top of the shell 31, and the bottom of the shell 31 is provided with a sewage outlet 313 that communicates with the cavity 311.

[0039] The rotating disk 32 is a disk structure as a whole. The rotating disk 32 is rotatably mounted on the housing 31. Its rotation axis coincides with its own axis, is perpendicular to the movement direction of the first movable member 22 and is inclined relative to the movement direction of the third movable member 24. The end of its rotation axis close to the placement area 211 is the inclined lower end. After the rotating disk 32 is mounted on the housing 31, part of it is located in the cavity 311 and part of it passes through the opening 312 and is located outside the housing 31.

[0040] The fourth driving member 33 is fixedly mounted on a side of the housing 31 close to the placement area 211, and can drive the rotating disk 32 to rotate relative to the housing 31. In this embodiment, the fourth driving member 33 is preferably a servo motor.

[0041] The interface 34 is fixedly mounted on one side of the edge of the rotating disk 32 close to the placement area 211, and multiple interfaces 34 are distributed in a circumferential array on the rotating disk 32 with the rotation axis of the rotating disk 32; the direction in which the interface 34 extends away from the rotating disk 32 is inclined relative to the rotation axis of the rotating disk 32, and the fourth driving member 33 drives the rotating disk 32 to rotate intermittently. After each rotation of the rotating disk 32, there is an interface 34 at the top and bottom of the rotating disk 32. At this time, the interface 34 located at the top of the rotating disk 32 is located outside the shell 31, which is used for plugging and unplugging with the charging pile 5. It extends in the direction close to the placement area 211 and the extension direction is parallel to the movement direction of the third movable member 24; and at this time, the interface 34 located at the bottom of the rotating disk 32 is located in the cavity 311, and it extends downward and the extension direction is parallel to the movement direction of the second movable member 23. In this embodiment, the interface module 3 preferably includes eight different types of interfaces 34; since the interface 34 with the charging pile 5 is a prior art in the art, it is not described here, and it is only briefly shown in the drawings.

[0042] Reference Figure 2 and Figure 3 , a power-consuming device 6 for simulating a vehicle to be charged is fixedly mounted on the top of the second movable member 23, and a line 7 for conducting electricity is connected between the power-consuming device 6 and the rotating disk 32, and multiple interfaces 34 can be energized through the rotating disk 32 and the line 7, and the power-consuming device 6 can be energized with the rotating disk 32 through the line 7 during the rotation of the rotating disk 32. In this embodiment, since the power-consuming device 6 with the above functions, the line 7, and the connection and energization method between the line 7 and the rotating disk 32 are all common existing technologies, they will not be described in detail here, and they are only briefly shown in the drawings.

[0043] Reference Figure 3 and Figure 4 Furthermore, when the interface 34 on the rotating disk 32 is not in use, external dust and other pollutants can easily enter the interface 34 to cause pollution, which will affect the data sensed and collected by the sensing module 4 when the interface 34 is used later, and even cause the circuit to be unable to connect.

[0044] Therefore, it is preferred that a drain port 313 for discharging dust and other pollutants is provided at the bottom of the housing 31, and the drain port 313 enables the cavity 311 to communicate with the space below the housing 31. Since, except for the interface 34 located at the top of the rotating disk 32, the other interfaces 34 are all oriented downwardly or vertically, it is not easy for dust and other pollutants from the outside to enter the above interfaces 34. At the same time, dust and other pollutants inside the interfaces 34 can also leave and fall to the bottom of the cavity 311 under the action of their own gravity, and finally be discharged through the drain port 313. In this embodiment, it is preferred that the size of the drain port 313 is larger than the radial cross-sectional size of the interface 34.

[0045] Furthermore, the opening 312 of the housing 31 is preferably oriented toward the placement area 211, and the direction of the opening 312 is perpendicular to the movement direction of the first movable member 22 and is inclined downward toward the placement area 211. At this time, external dust and other pollutants are not easy to enter the cavity 311 through the opening 312, and thus are not easy to enter the interior of the interface 34 located in the cavity 311.

[0046] Reference Figure 4 and Figure 5 Furthermore, in order to effectively reduce the probability that dust and other pollutants inside the interface 34 affect the aging detection, the interface module 3 preferably also includes a cleaning device 35 for cleaning dust and other pollutants inside the interface 34.

[0047] The cleaning device 35 includes a fan 351, a plurality of air pipes 352, and a plurality of air nozzles 353. The fan 351 is used to drive the gas flow; the air pipes 352 are used to guide the gas flow; the air nozzles 353 are used to guide the direction of the gas blowing out, and the dust and other pollutants inside the interface 34 are cleaned by the gas.

[0048] The fan 351 is fixedly mounted on one side of the housing 31 near the placement area 211 and is located on one side of the fourth driving member 33; the air nozzle 353 is fixedly mounted on the housing 31 and is located in the cavity 311; multiple air pipes 352 correspond to multiple air nozzles 353 one by one, one end of the air pipe 352 is connected to the fan 351, and the other end penetrates into the housing 31 and is connected to the corresponding air nozzle 353. In this embodiment, the cleaning device 35 preferably includes four air pipes 352 and four air nozzles 353, and the positions of the four air nozzles 353 on the housing 31 preferably correspond to the four interfaces 34 on the rotating disk 32 near the sewage outlet 313 except the interface 34 at the bottom.

[0049] The air nozzle 353 is located in the cavity 311 on one side thereof close to the fan 351, and the air nozzle 353 can guide the gas to enter the interior of the interface 34 in a direction inclined relative to the extension direction of the interface 34; since the interior of the interface 34 actually has a plurality of rod-shaped plug connectors, the air flow after the gas blown out by the air nozzle 353 enters the interior of the interface 34 will be able to fully diffuse inside the interface 34, and pollutants such as dust will leave the interior of the interface 34 after being blown away by the gas, making the cleaning effect more comprehensive and effective.

[0050] Furthermore, in order to make the cleaning effect of the cleaning device 35 on the inside of the interface 34 more efficient and reduce the energy consumption of the cleaning device 35 during the cleaning process of the inside of the interface 34, the fan 351 is preferably signal-connected to the fourth driving member 33.

[0051] The cleaning device 35 is usually in a standby state. When the fourth driving member 33 drives the rotating disk 32 to rotate, the fan 351 starts to operate, so that the cleaning device 35 can blow air to clean the inside of the interface 34 during the rotation of the rotating disk 32. At this time, the interface 34 changes position as the rotating disk 32 rotates, so that the cleaning position of the air blown by the air nozzle 353 on the inside of the interface 34 changes, thereby further improving the cleaning effect of the cleaning device 35 on the inside of the interface 34.

[0052] Reference Figure 1 and Figure 2 Furthermore, in order to facilitate the test personnel to place and position the charging pile 5 in the placement area 211, and at the same time facilitate the driving module 2 to drive the interface module 3 and the charging pile 5 to achieve plug-in cooperation, the driving module 2 preferably also includes a limit member 28 for limiting the position of the charging pile 5 above the base 21.

[0053] The limiting member 28 is a rectangular plate-shaped structure as a whole, which is fixedly installed at one end of the base 21 away from the first movable member 22, and is located on the side of the placement area 211 away from the first movable member 22; after the charging pile 5 is placed in the placement area 211 with the limiting member 28 as a limiting aid, the charging pile 5 will fit against the end surface of the limiting member 28, and at this time, the direction of the socket on the charging pile 5 is parallel to the moving direction of the third movable member 24. In this embodiment, it is preferred that the height dimension of the limiting member 28 is equivalent to the height dimension of the pile.

[0054] When the driving module 2 drives the interface 34 on the top of the rotating disk 32 of the interface module 3 to be plugged into the socket on the charging pile 5, the limiting member 28 can prevent the charging pile 5 from being displaced in a direction away from the first movable member 22 after being acted upon by the interface 34, thereby facilitating the plugging process of the interface 34 and the charging pile 5. In this embodiment, the surface of the top of the base 21 preferably has a larger friction coefficient in the placement area 211, that is, the surface is relatively rough, so as to effectively improve the position stability of the charging pile 5 in the placement area 211.

[0055] Reference Figure 1 and Figure 2 The sensing module 4 includes a temperature sensor 41, a humidity sensor 42, a current sensor 43 and a voltage sensor 44, which are respectively used to monitor the temperature, humidity, current and voltage of the charging pile 5 during the aging test, and can collect data and upload it to the background.

[0056] The temperature sensor 41 and the humidity sensor 42 are both fixedly mounted on the top of the stopper 28, and when the charging pile 5 and the end surface of the stopper 28 are in contact with each other, the temperature sensor 41 can also contact and abut against the surface of the charging pile 5; the current sensor 43 and the voltage sensor 44 are both fixedly mounted on the power-consuming device 6, and can sense and collect the current and voltage after power is supplied between the power-consuming device 6 and the charging pile 5. In this embodiment, since the temperature sensor 41, the humidity sensor 42, the current sensor 43 and the voltage sensor 44 with the above functions are all common prior arts, they are not described here in detail, and they are only briefly indicated in the drawings.

[0057] The control module 1 is fixedly mounted on the base 21, and is simultaneously connected to the drive module 2, the interface module 3, and the sensing module 4 by signal. The tester can control the drive module 2 to drive the interface module 3 to move, control the interface module 3 to drive the rotating disk 32 to rotate and switch the interface 34 used, and control the sensing module 4 to open and close and transmit data through the control module 1. In this embodiment, the control module 1 is preferably located at a position of the base 21 away from the limiter 28, and is located on one side of the drive module 2 along the width direction of the base 21; since the control module 1 with the above functions is a common prior art, it will not be described in detail here, and it is only briefly shown in the drawings.

[0058] The implementation principle of a stable interface structure for charging pile aging test in the embodiment of the present application is as follows: After the charging pile 5 is positioned in the placement area 211 and the charging pile 5 is in contact with the end surface of the limiter 28, the tester operates the control module 1 to control the fourth drive member 33 to drive the rotating disk 32 to rotate, so that the interface 34 adapted to the charging pile 5 rotates to the top of the rotating disk 32. During this process, the cleaning device 35 will keep running to blow and clean the dust and other pollutants inside the multiple interfaces 34 passing around the multiple air nozzles 353. The cleaned dust and other pollutants will be discharged through the sewage outlet 313 at the bottom of the shell 31. Then the tester operates the control module 1 again to control the first drive member 25 , the second driving member 26 and the third driving member 27 respectively drive the first movable member 22, the second movable member 23 and the third movable member 24 to move, so that the interface 34 located at the top of the rotating disk 32 is aligned with the socket on the charging pile 5; then the tester operates the control module 1 to control the third driving member 27 to drive the third movable member 24 to reciprocate, so that the interface 34 located at the top of the rotating disk 32 and the charging pile 5 can be repeatedly plugged in and out. During this process, the sensing module 4 keeps running to monitor the temperature, humidity, current, voltage and other parameters of the charging pile 5, and transmits the collected data to the background to facilitate the tester to analyze and draw conclusions later.

[0059] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
