Description

Technical Field

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

[0002] Wireless charging is a technology that uses the principle of electromagnetic field induction or other wireless energy transmission technologies to achieve wireless transmission of electrical energy from the power source to the power-consuming device. There is no need to use traditional charging cables. Wireless charging devices need to be tested because the test can ensure that their charging efficiency meets the standards, allowing users to obtain a fast and efficient charging experience. For example, the patent with authorization announcement number CN212341344U discloses a wireless charging test device.

[0003] At present, some wireless charging equipment manufacturers have significant problems in the product testing process. In order to highlight the performance and charging effect of the equipment, they often select the best environment for testing, resulting in the performance of some wireless charging equipment on the market failing to meet the actual needs of customers. For example, the test temperature is strictly controlled within the ideal working range of 20-25 degrees Celsius for wireless charging equipment, and the receiving coil is accurately placed in the center of the transmitting coil in the wireless charging equipment. However, this testing method is very different from the actual use scenario of wireless charging equipment. In actual use of the wireless charging equipment purchased by customers, high temperatures in summer and low temperatures in winter will change the inductance and resistance parameters of the receiving coil and the transmitting coil, making the existing test results lack of representativeness, seriously affecting the accuracy of the test; In addition, the existing wireless charging test process is imperfect and lacks simulation testing of charging performance in a dynamic vehicle environment. For example, bumps during vehicle driving can cause the receiving coil of the charged device to shake or vibrate, and existing tests cannot determine whether the wireless charging device can reliably transmit electrical energy in this situation, resulting in incomplete testing, which in turn reduces the reliability of the use of wireless charging measurement devices.

[0004] To this end, we propose a wireless charging test device and a test method to solve the above problems. Summary of the invention

[0014] A test method for a wireless charging test device, the test method includes the following steps: Step S1, first randomly select the wireless charging device to be tested in the market, and clamp the wireless charging device on the U-shaped fixing frame through the limiting mechanism; Step S2, then control the movement of the mobile end of the first electric push rod through the PLC controller. The mobile end of the first electric push rod pushes the test mechanism to approach the surface of the charging area of the wireless charging device. Then the test feedback component conducts multiple index tests, and the test feedback component transmits the collected test data to the PLC controller in the form of an electric signal, and then transmits it to the AI large model pre-installed in the integrated computer through the PLC controller for the first preliminary data analysis; Step S3: After 5 minutes of testing in Step S2, the PLC controller controls the test mechanism to conduct a wireless charging test under a simulated vehicle bump dynamic environment. First, the PLC controller rotates the trapezoidal hollow hard sheet through the servo motor and raises the protective thin sheet. After the trapezoidal hollow hard sheet moves away from the protective thin sheet, the protective thin sheet can contact the wireless charging area of the wireless charging device again, thereby simulating the working state of the wireless charging device under the vehicle bump environment. Moreover, in cooperation with the displacement mechanism, it further simulates wireless charging under the vehicle dynamic environment. Then, the test feedback component receives the test data, and the test data received by the test feedback component is transmitted to the AI large model pre-installed in the integrated computer for the second preliminary data analysis; Step S4: There are three modes for setting the rotation speed of the servo motor in Step S3.

And the test time for each mode is 5 minutes. After each wireless charging test under the vehicle bump dynamic environment, the test feedback component will transmit the generated test data to the AI large model pre-installed in the integrated computer for rapid analysis; Step S5: After Step S4 is completed, the PLC controller controls the hollow hard tube to rotate 180 degrees, and the trapezoidal hollow hard sheet rotates to directly below the protective thin sheet. Then, the PLC controller controls the air pump to start. The air pump sucks air and injects it multiple times to make the expansion rubber cover bulge. After each air injection is completed, the infrared distance sensor measures the distance value between the receiving coil and the charging surface of the wireless charging device and sends the distance value to the PLC controller in the form of an electrical signal. At the same time, the test feedback component still collects the corresponding test data for 5 minutes and transmits it to the AI large model pre-installed in the integrated computer for the third preliminary analysis; Step S6: The temperature environment simulation mechanism changes the temperature environment inside the shield, and controls the temperature range to change from minus 10 degrees Celsius to 50 degrees Celsius to test the wireless charging performance of the wireless charging device under different temperature environments. During the test, the environmental temperature inside the shield increases by 5 degrees Celsius each time. After each temperature increase, the test device repeats the test processes of Step S2, Step S3, Step S4, and Step S5. And all these test data are transmitted to the AI large model pre-installed in the integrated computer through the test feedback component and the PLC controller for the fourth preliminary analysis; Step S7: After Step S6 ends, the AI large model pre-installed in the integrated computer reorganizes all the test data for comprehensive analysis and can quickly obtain detailed and accurate test results to determine whether the wireless charging performance of the wireless charging device meets the customer's usage requirements.

[0015] Compared with the existing technology, the advantages of a wireless charging test device and a test method are as follows: 1. With the set limit mechanism, test mechanism, test feedback mechanism and integrated computer, when a wireless charging device is subjected to a wireless charging test, first randomly select the wireless charging device to be tested on the market, and clamp the wireless charging device on the U-shaped fixing frame through the limit mechanism. Then, control the movement of the mobile end of the first electric push rod through the PLC controller. The mobile end of the first electric push rod pushes the test mechanism close to the surface of the charging area of the wireless charging device. Then, the test feedback component conducts multiple index tests, and the test feedback component transmits the collected test data to the PLC controller in the form of electrical signals. Then, it is transmitted to the AI large model pre-installed in the integrated computer through the PLC controller for data analysis. This mechanism enables the wireless charging test device to have the function of static testing of wireless charging devices, and the test results are fed back through the test feedback component, which can accurately test the performance of wireless charging devices and improve the reliability of the use of the test device.

[0016] 2. With the set servo motor, trapezoidal hollow hard thin sheet and test feedback component, the PLC controller controls the test mechanism to conduct a wireless charging test under a simulated vehicle bump dynamic environment. First, the PLC controller rotates the trapezoidal hollow hard thin sheet through the servo motor, and the protective thin sheet is lifted. After the trapezoidal hollow hard thin sheet moves away from the protective thin sheet, the protective thin sheet can contact the wireless charging area of the wireless charging device again, so as to simulate the working state of the wireless charging device under the vehicle bump environment. The rotation speed of the servo motor is set in three modes, namely low speed mode, medium speed mode and high speed mode, and the test time for each mode is 5 minutes. After each wireless charging test under the vehicle bump dynamic environment, the test feedback component will transmit the generated test data to the AI large model pre-installed in the integrated computer for rapid analysis. This mechanism of the test device also has the function of simulating wireless charging tests under the vehicle dynamic environment. By simulating bumps in different speed modes, it makes up for the shortcoming of the existing test lacking dynamic scenarios, makes the test results richer, can not only accurately test the performance of wireless charging devices, but also improve the reliability of the use of the test device.

[0017] 3. Through the provided infrared distance sensor, test feedback component, and expansion rubber cover, the PLC controller controls the hollow hard tube to rotate 180 degrees, and the trapezoidal hollow hard sheet rotates to directly below the protective thin plate. Then, the PLC controller controls the air pump to start. The air pump sucks in air and injects it multiple times to make the expansion rubber cover bulge. After each air injection, the infrared distance sensor measures the distance value between the receiving coil and the charging surface of the wireless charging device, and transmits the distance value to the PLC controller as an electrical signal. At the same time, the test feedback component still collects corresponding test data for 5 minutes and transmits it to the AI large model pre-installed in the integrated computer for analysis. Moreover, after each air injection, the test feedback component tests for 5 minutes to ensure the richness of the measured data collection until the maximum effective charging distance value between the receiving coil and the wireless charging device is obtained. At the same time, the performance of the wireless charging device's wireless charging is reflected by the size of the maximum effective charging distance value. Further, the test results are more abundant, which can accurately test the performance of the wireless charging device and improve the reliability of the test device's use.

[0018] 4. Through the provided temperature environment simulation mechanism, the temperature environment inside the protective cover is changed by the temperature environment simulation mechanism, and the temperature range is controlled to change from minus 10 degrees Celsius to 50 degrees Celsius, so as to test the wireless charging performance of the wireless charging device under different temperature environments. During the test, the ambient temperature inside the protective cover increases by 5 degrees Celsius each time. After each temperature increase, the test device repeats the test process of the wireless charging device in a static state, a simulated vehicle dynamic environment, and the maximum wireless charging distance. And all these test data are transmitted to the AI large model pre-installed in the integrated computer through the test feedback component and the PLC controller for a fourth preliminary analysis to determine whether the wireless charging performance of the wireless charging device meets the customer's usage requirements. This mechanism simulates and fully tests the wireless charging performance of the wireless charging device at different temperatures through the temperature environment simulation mechanism, highly restoring the actual usage environment, greatly improving the test accuracy. And by deeply analyzing the data with the help of the AI large model, accurate results can be quickly obtained, improving the convenience and efficiency of the wireless charging test.

At the same time, the transmitting coil of the wireless charging device is aligned with the receiving coil 715 in the testing mechanism 7; Specifically, by rotating the rotating block 53 to rotate the screw rod 52, the screw rod 52 extends out of the threaded cylinder 51. At the same time, the screw rod 52 pushes the L-shaped clamping block 55 close to the wireless charging device and stably clamps the wireless charging device. Then, by pulling the bent rod 4, the glass gate 3 is pushed to close, and the glass gate 3 seals the opening of the protective cover 2; Next, the PLC controller 11 controls the movement of the mobile end of the first electric push rod 10. The mobile end of the first electric push rod 10 pushes the test mechanism 7 close to the surface of the charging area of the wireless charging device. The lower surfaces of the trapezoidal hollow hard thin sheet 74 and the protective thin sheet 714 in the test mechanism 7 are in contact with the surface of the charging area of the wireless charging device. At the same time, the infrared distance sensor 716 measures the distance from the surface of the charging area of the wireless charging device. The infrared distance sensor 716 converts the detected distance value into an electrical signal and transmits it to the PLC controller 11. If the distance data value detected by the infrared distance sensor 716 is the thickness threshold of the protective thin sheet 714 preset by the PLC controller 11, the PLC controller 11 timely controls the first electric push rod 10 to pause moving. And at this time, the wireless charging device is powered by the power socket 13, so that electric energy is transmitted to the receiving coil 715 in a wireless form, simulating wireless charging between the wireless charging device and the device to be charged in a static state. Then the test feedback component 8 conducts multiple index tests, and the test feedback component 8 transmits the collected test data to the AI large model pre-installed in the all-in-one computer 14 for the first preliminary data analysis; Specifically, after the receiving coil 715 receives electric energy, the current sent out by the receiving coil 715 is processed by the current stabilizer 81. Then the electric energy sent out by the receiving coil 715 drives the load motor 82 to rotate. The load motor 82 drives the detection end of the rotational speed sensor 83 to rotate, and detects whether the rotational speed of the load motor 82 is continuously stable and reliable. If the rotational speed of the load motor 82 detected by the rotational speed sensor 83 rotates continuously and stably, it means that the wireless charging device can continuously and reliably supply electric energy to the receiving coil 715. On the contrary, if the rotational speed of the load motor 82 is fast and slow, it means that the stability of the electric energy supplied by the wireless charging device is poor and does not meet the normal use. Moreover, the voltage and current of the electric energy supplied by the receiving coil 715 can be detected by the electronic ammeter 85 and the electronic voltmeter 86, and the actual charging power of the wireless charging device is fed back. Finally, the test feedback component 8 transmits the test data to the AI large model pre-installed in the all-in-one computer 14 for rapid analysis; After the process is tested for 5 minutes, the PLC controller 11 controls the test mechanism 7 to conduct a wireless charging test in a vehicle bump dynamic environment. First, the PLC controller 11 controls the servo motor 72 to rotate. The servo motor 72 drives the trapezoidal hollow hard thin sheet 74 to rotate through the hollow hard tube 73. During the rotation of the trapezoidal hollow hard thin sheet 74, it will cross-cut the lower surface of the protective thin plate 714 and lift the protective thin plate 714. The protective thin plate 714 drives the receiving coil 715 and the L-shaped plate 713 to rise. After the position of the L-shaped plate 713 rises, it will squeeze the return spring 19. The return spring 19 compresses and stores energy, and ensures that after the trapezoidal hollow hard thin sheet 74 moves away from the protective thin plate 714, the protective thin plate 714 can contact the wireless charging area of the wireless charging device again, so as to simulate the working state of the wireless charging device in a vehicle bump environment, that is, the process of the device to be charged leaving the wireless charging device briefly and then falling back to the wireless charging device. Then, the wireless charging device is powered by the power socket 13 and the electric energy is wirelessly transmitted to the receiving coil 715. Then, the test feedback component 8 receives the test data, and the test data received by the test feedback component 8 is transmitted to the PLC controller 11, and then transmitted to the AI large model pre-installed in the all-in-one computer 14 for secondary preliminary data analysis. Moreover, the rotation speed of the servo motor 72 is set in three modes, namely, low-speed mode, medium-speed mode and high-speed mode. The low-speed mode simulates the wireless charging device charging in a slightly bumpy vehicle environment, the medium-speed mode simulates the wireless charging device charging in a bumpy vehicle environment, and the high-speed mode simulates the wireless charging device charging in a severely bumpy vehicle environment. And the test time for each mode is 5 minutes. After each wireless charging test in the vehicle bump dynamic environment, the test feedback component 8 will transmit the generated test data to the AI large model pre-installed in the all-in-one computer 14 for rapid analysis. After the test is completed, the servo motor 72 controls the position of the trapezoidal hollow hard thin sheet 74 to return to the initial state, and the included angle with the receiving coil 715 is 180 degrees; Moreover, during each wireless charging test in the vehicle bump dynamic environment, the PLC controller 11 also controls the second electric push rod 64 at the mobile end of the displacement mechanism 6 to contract arbitrarily. The second electric push rod 64 changes the position of the receiving coil 715 by a small displacement through the connecting bearing 61, the moving frame 62 and the moving rod 63, so as to simulate the influence of the displacement change between the wireless charging device and the device to be charged on wireless charging under bumpy conditions; After the wireless charging test is completed under the simulated vehicle bump environment, the PLC controller 11 controls the hollow hard tube 73 to rotate 180 degrees, and the trapezoidal hollow hard thin sheet 74 rotates to directly below the protective thin plate 714. Then, the PLC controller 11 controls the air extraction pump 93 to start. The air extraction pump 93 sucks air and transports it through the heat insulation box 91 and the air duct 95 to the three-way reversing solenoid valve 911. The PLC controller 11 controls the three-way reversing solenoid valve 911 to be energized and opened. After that, the air in the air inlet pipe 910 enters the hose 912 through the energized and opened three-way reversing solenoid valve 911, then enters the hollow hard tube 73 through the hollow block 711, the micro air flow meter 712, and the elbow 710. After that, the air enters the inside of the trapezoidal hollow hard thin sheet 74, and at the same time, the expansion rubber cover 76 bulges. During this process, the micro air flow meter 712 detects the air flow rate injected into the trapezoidal hollow hard thin sheet 74. If the air flow rate detected by the micro air flow meter 712 reaches the air flow rate threshold preset by the PLC controller 11, the PLC controller 11 controls the three-way reversing solenoid valve 911 to be de-energized, and stops injecting air into the trapezoidal hollow hard thin sheet 74. After each air injection is completed, the infrared distance sensor 716 measures the distance value between the receiving coil 715 and the charging surface of the wireless charging device, and transmits the distance value to the PLC controller 11 as an electrical signal. And after each change in the distance value between the receiving coil 715 and the charging area surface of the wireless charging device, the test feedback component 8 still collects the corresponding test data and transports it into the AI large model pre-installed in the all-in-one computer 14 for the third preliminary analysis. Moreover, after each air injection is completed, the test feedback component 8 tests for 5 minutes to ensure the richness of the measurement data collection, until the maximum effective charging distance value between the receiving coil 715 and the wireless charging device is obtained, and at the same time, the performance of the wireless charging of the wireless charging device is reflected by the size of the maximum effective charging distance value; During the wireless charging test, the temperature environment simulation mechanism 9 changes the temperature environment inside the shield 2, and controls the temperature range to vary from minus 10 degrees Celsius to 50 degrees Celsius, so as to test the wireless charging performance of the wireless charging device under different temperature environments. At this time, the PLC controller 11 controls the air extraction pump 93, the semiconductor refrigeration sheet 99 and the electric heating tube 97 to work. The work of the semiconductor refrigeration sheet 99 and the electric heating tube 97 can change the temperature of the surface of the air guide metal plate 96. The air extraction pump 93 sucks air and conveys it to the air guide metal plate 96 through the air guide pipe 95. The air is changed by the temperature of the surface of the air guide metal plate 96, and then the air with changed temperature enters the air inlet pipe 910. The temperature of the air in the air inlet pipe 910 is fed back to the PLC controller 11 through the temperature sensor 913. The PLC controller 11 controls the heating power of the electric heating tube 97 according to the signal fed back by the temperature sensor 913, so as to make the temperature of the air entering the air inlet pipe 910 meet the range of minus 10 degrees Celsius to 50 degrees Celsius. And during the test, the environmental temperature inside the shield 2 increases by 5 degrees Celsius every time, and after each temperature increase, the test device will repeat the above test steps to obtain the test results of the static wireless charging performance, the charging performance under the dynamic environment of vehicle bump and the maximum effective wireless charging distance of the wireless charging device at this temperature. And all these test data are sent to the AI large model pre-installed in the all-in-one computer 14 through the test feedback component 8 and the PLC controller 11 for the fourth preliminary analysis. After the fourth preliminary analysis, the AI large model pre-installed in the all-in-one computer 14 reorganizes all the test data for comprehensive analysis, and can quickly obtain detailed and accurate test results to determine whether the wireless charging performance of the wireless charging device meets the customer's usage requirements; In summary, the wireless charging test device can conduct various tests on randomly purchased wireless charging devices. Through the temperature environment simulation mechanism 9, it simulates the wireless charging performance test of the wireless charging device at different temperatures, highly restores the actual use environment, greatly improves the test accuracy. Moreover, the test device also has the function of simulating wireless charging tests in static and vehicle dynamic environments. It simulates bumps through different speed modes, making up for the shortcoming of the existing test lacking dynamic scenarios, making the test results richer. It can not only accurately test the performance of the wireless charging device, but also improve the reliability of the use of the test device. And the test device uses the AI large model to deeply analyze data, can quickly obtain accurate results, helps to judge whether the wireless charging device meets the customer's needs, and improves the convenience and efficiency of the wireless charging test.
