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, without the need for 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] Currently, some wireless charging device manufacturers have significant problems in the product testing process. To highlight device performance and charging results, they often select the optimal environment for testing. As a result, the performance of some wireless charging devices on the market does not meet the actual needs of customers. For example, the test temperature is strictly controlled within the ideal operating range of 20-25 degrees Celsius for wireless charging devices, and the receiving coil is precisely placed at the center of the transmitting coil in the wireless charging device. However, this testing method is very different from the actual use scenarios of wireless charging devices. In actual use of wireless charging devices purchased by customers, high temperatures in summer and low temperatures in winter will change the inductance and resistance parameters of the receiving coil and transmitting coil, making the existing test results unrepresentative and seriously affecting test accuracy.

[0004] In addition, the existing wireless charging testing process is imperfect and lacks simulation testing of charging performance in dynamic vehicle environments. For example, bumps during vehicle driving can cause the receiving coil of the charged device to shake or vibrate. Existing tests cannot determine whether the wireless charging device can reliably transmit power in such conditions, resulting in incomplete testing and reduced reliability of the wireless charging measurement device.

[0005] To this end, we propose a wireless charging test device and test method to solve the above problems. Summary of the Invention

[0017] A testing method for a wireless charging test device, the testing method comprising the following steps:

[0018] Step S1: First, randomly purchase a wireless charging device to be tested on the market, and clamp the wireless charging device on a U-shaped fixing frame through a limiting mechanism;

[0019] Step S2: Then, the PLC controller controls the movement of the first electric linear actuator. The first electric linear actuator pushes the test mechanism close to the charging area surface of the wireless charging device. Then, the test feedback component performs multiple index tests, and the test feedback component transmits the collected test data to the PLC controller in the form of electrical signals. The data is then transmitted to the AI ​​large model pre-installed in the integrated computer through the PLC controller for the first preliminary data analysis.

[0020] Step S3: 5 minutes after the test in step S2, the PLC controller controls the test mechanism to perform a wireless charging test in a simulated vehicle bumpy dynamic environment. First, the PLC controller rotates the trapezoidal hollow hard sheet through the servo motor and lifts the protective sheet. After the trapezoidal hollow hard sheet moves away from the protective sheet, the protective sheet can once again contact the wireless charging area of ​​the wireless charging device, thereby simulating the operation of the wireless charging device in a bumpy vehicle environment. The shift mechanism further simulates wireless charging in a dynamic vehicle 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 a second preliminary data analysis.

[0021] Step S4: In step S3, the servo motor rotation speed is set to three modes: 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. The test time for each mode is 5 minutes. After each wireless charging test in a dynamic vehicle bumpy environment, the test feedback component will transmit the generated test data to the AI ​​large model pre-installed on the integrated computer for rapid analysis.

[0022] Step S5: After step S4 is completed, the PLC controller controls the hollow rigid tube to rotate 180 degrees, and the trapezoidal hollow rigid sheet to rotate to directly below the protective sheet. The PLC controller then controls the vacuum pump to start, and the vacuum pump sucks air and injects it multiple times to inflate the expandable rubber cover. After each air injection, the infrared ranging sensor measures the distance 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 will continue to collect 5 minutes of corresponding test data and transmit it to the AI ​​large model pre-installed in the integrated computer for a third preliminary analysis.

[0023] Step S6: The temperature environment inside the shield is changed by the temperature environment simulation mechanism, and the temperature range is controlled to change from -10 degrees Celsius to 50 degrees Celsius to meet the wireless charging performance of the wireless charging device under different temperature environments. During the test, the ambient temperature inside the shield is increased by 5 degrees Celsius. After each temperature increase, the test device repeats the test process of steps S2, S3, S4 and S5. 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.

[0024] Step S7: After step S6, the AI ​​large model pre-installed on the all-in-one computer organizes 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 needs.

[0025] Compared with existing technologies, the advantages of a wireless charging test device and test method are:

[0026] Through the set limiting mechanism, testing mechanism, test feedback mechanism and integrated computer, when the wireless charging device is undergoing a wireless charging test, the wireless charging device to be tested is first randomly selected from the market, and the wireless charging device is clamped on the U-shaped fixed frame through the limiting mechanism, and then the first electric push rod moving end is controlled to move by the PLC controller, and the first electric push rod moving end pushes the test mechanism close to the charging area surface of the wireless charging device, and then the test feedback component performs multiple index tests, and the test feedback component transmits the collected test data to the PLC controller in the form of an electrical signal, and then transmits it 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 equipment, and the test results are fed back through the test feedback component, which can accurately test the performance of the wireless charging device and improve the reliability of the use of the test device.

[0027] Through the set servo motor, trapezoidal hollow hard sheet and test feedback component, the PLC controller controls the test mechanism to perform wireless charging tests under simulated vehicle-mounted bumpy dynamic environments. First, the PLC controller rotates the trapezoidal hollow hard sheet through the servo motor and lifts the protective sheet. After the trapezoidal hollow hard sheet moves away from the protective sheet, the protective sheet can contact the wireless charging area of ​​the wireless charging device again, thereby simulating the working state of the wireless charging device under a bumpy vehicle environment. The servo motor rotation speed 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 a bumpy vehicle dynamic environment, the test feedback component will transfer the generated test data to the AI ​​large model pre-installed on the integrated computer for rapid analysis. The test device of this mechanism also has the function of simulating wireless charging tests under a dynamic vehicle-mounted environment. By simulating bumps through different speed modes, it makes up for the shortcomings of the existing test that lacks dynamic scenarios, making the test results richer, not only accurately testing the performance of the wireless charging device, but also improving the reliability of the test device.

[0028] Through the set infrared ranging 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 to rotate to the bottom of the protective sheet. Then the PLC controller controls the vacuum pump to start, and the vacuum pump sucks air and injects it multiple times to make the expansion rubber cover bulge. After each air injection, the infrared ranging sensor measures the distance between the receiving coil and the charging surface of the wireless charging device, and transmits the distance value to the PLC controller in the form of an electrical signal. At the same time, the test feedback component will still collect 5 minutes of corresponding test data and transmit 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 measurement 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 size of the maximum effective charging distance value reflects the wireless charging performance of the wireless charging device. Further test results are richer, the performance of the wireless charging device can be accurately tested, and the reliability of the test device can be improved.

[0029] Through the set temperature environment simulation mechanism, the temperature environment inside the shield is changed through the temperature environment simulation mechanism, and the temperature range is controlled to change from minus 10 degrees Celsius to 50 degrees Celsius to meet the needs of testing the wireless charging performance of the wireless charging device under different temperature environments. During the test, the ambient temperature inside the shield increases by 5 degrees Celsius, and after each temperature increase, the test device will repeat the test process of the wireless charging device in static state, simulated vehicle dynamic environment and maximum wireless charging distance. These test data are transmitted to the AI ​​large model pre-installed on the all-in-one computer through the test feedback component and PLC controller for the fourth preliminary analysis to determine whether the wireless charging performance of the wireless charging device meets the customer's usage needs. The mechanism simulates the wireless charging performance test of the wireless charging device at different temperatures through the temperature environment simulation mechanism, highly restores the actual usage environment, greatly improves the test accuracy, and uses the AI ​​large model to deeply analyze the data, which can quickly obtain accurate results and improve the convenience and efficiency of wireless charging testing.

[0049] Then, the PLC controller 11 controls the movement of the first electric push rod 10, and the first electric push rod 10 pushes the test mechanism 7 close to the surface of the charging area of ​​the wireless charging device, and the lower surface of the trapezoidal hollow hard sheet 74 and the protective sheet 714 in the test mechanism 7 contacts the surface of the charging area of ​​the wireless charging device. At the same time, the infrared distance sensor 716 measures the distance to 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 PLC controller 1 When the thickness of the protective sheet 714 reaches a preset threshold, the PLC controller 11 promptly controls the first electric push rod 10 to pause, and at this time the wireless charging device supplies power through the power socket 13, so that the power is wirelessly transmitted to the receiving coil 715, simulating static wireless charging between the wireless charging device and the charged device. Then, the test feedback component 8 performs multiple indicator tests, and the test feedback component 8 transmits the collected test data in the form of electrical signals to the PLC controller 11, which is then transmitted through the PLC controller 11 to the pre-installed AI large model in the integrated computer 14 for the first preliminary data analysis;

[0050] Specifically, after the receiving coil 715 receives the electric energy, the current generated by the receiving coil 715 is processed by the current stabilizer 81. Then, the electric energy generated by the receiving coil 715 drives the load motor 82 to rotate, and the load motor 82 drives the detection end of the speed sensor 83 to rotate, and detects whether the speed of the load motor 82 is continuously stable and reliable. If the speed of the load motor 82 detected by the speed sensor 83 rotates continuously and stably, it means that the wireless charging device can continuously and reliably transmit electric energy to the receiving coil 715. On the contrary, if the speed of the load motor 82 is fast and slow, it means that the stability of the electric energy transmitted by the wireless charging device is poor and does not meet normal use. In addition, the voltage and current of the electric energy transmitted 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 can be fed back. Finally, the test feedback component 8 transmits the test data to the AI ​​large model pre-installed in the integrated computer 14 for rapid analysis.

[0051] After the process is tested for 5 minutes, the PLC controller 11 controls the test mechanism 7 to perform a wireless charging test under a dynamic vehicle bumpy environment. First, the PLC controller 11 controls the servo motor 72 to rotate. The servo motor 72 drives the trapezoidal hollow hard sheet 74 to rotate through the hollow hard tube 73. During the rotation of the trapezoidal hollow hard sheet 74, it will cross the lower surface of the protective sheet 714 and lift the protective sheet 714. The protective sheet 714 drives the receiving coil 715 and the L-shaped plate 713 to rise. After the L-shaped plate 713 rises, it will squeeze the return spring 19. The return spring 19 compresses and stores energy, and ensures that the trapezoidal hollow hard sheet 74 is away from the protective sheet 714. The protective sheet 714 can contact the wireless charging area of ​​the wireless charging device again, thereby simulating the working state of the wireless charging device under a bumpy vehicle environment, that is, the process in which the charged device briefly leaves the wireless charging device and then falls 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, and then the test is carried out. The 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 integrated computer 14 through the PLC controller 11 for a second preliminary data analysis. The rotation speed of the servo motor 72 is set to 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. The test time for each mode is 5 minutes. After each wireless charging test in a dynamic vehicle bumpy environment, the test feedback component 8 will transmit the generated test data to the AI ​​large model pre-installed in the integrated computer 14 for rapid analysis. After the test is completed, the servo motor 72 controls the position of the trapezoidal hollow hard sheet 74 to return to the initial state, and the angle between it and the receiving coil 715 is 180 degrees.

[0052] Furthermore, during each wireless charging test under a dynamic vehicle bumpy environment, the PLC controller 11 also controls the movable end of the second electric push rod 64 in the displacement mechanism 6 to arbitrarily retract. The second electric push rod 64 changes the position of the receiving coil 715 by a small displacement through the connection bearing 61, the movable frame 62, and the movable rod 63, thereby simulating the effect of the displacement change between the wireless charging device and the charged device on wireless charging under bumpy conditions.

[0053] After the wireless charging test is completed in the simulated vehicle bumpy environment, the PLC controller 11 controls the hollow hard tube 73 to rotate 180 degrees, and the trapezoidal hollow hard sheet 74 rotates to the bottom of the protective sheet 714. Then the PLC controller 11 controls the vacuum pump 93 to start. The vacuum pump 93 sucks air through the heat insulation box 91 and the air guide pipe 95 and transmits it 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. Then, the air in the intake pipe 910 enters the hose 912 through the energized and opened three-way reversing solenoid valve 911, and then is injected into the hollow hard tube 73 through the hollow block 711, the micro airflow flowmeter 712 and the elbow 710. Then, the air enters the interior of the trapezoidal hollow hard sheet 74 and causes the expansion rubber cover 76 to swell. During this process, the micro airflow flowmeter 712 detects the air flow rate injected into the trapezoidal hollow hard sheet 74. If the air flow rate detected by the micro airflow flowmeter 712 reaches PL After the air flow threshold preset by the C controller 11 is reached, the PLC controller 11 controls the three-way reversing solenoid valve 911 to cut off power and stop the air injection into the trapezoidal hollow hard sheet 74. After each air injection, the infrared ranging sensor 716 measures the distance between the receiving coil 715 and the charging surface of the wireless charging device, and transmits the distance value to the PLC controller 11 in the form of an electrical signal. After each change in the distance between the receiving coil 715 and the charging area surface of the wireless charging device, the test feedback component 8 will still collect the corresponding test data and transmit it to the AI ​​large model pre-installed in the integrated computer 14 for a third preliminary analysis. After each air injection, the test feedback component 8 will test for 5 minutes to ensure the richness of the measurement data collection until the maximum effective charging distance between the receiving coil 715 and the wireless charging device is obtained. At the same time, the size of the maximum effective charging distance reflects the wireless charging performance of the wireless charging device.

[0054] During the wireless charging test, the temperature environment simulation mechanism 9 changes the temperature environment inside the protective cover 2, and controls the temperature range from -10 degrees Celsius to 50 degrees Celsius to meet the requirements of testing the wireless charging performance of the wireless charging device under different temperature environments. At this time, the PLC controller 11 controls the operation of the vacuum pump 93, the semiconductor refrigeration plate 99 and the electric heating tube 97. The operation of the semiconductor refrigeration plate 99 and the electric heating tube 97 can change the surface temperature of the air guide metal plate 96. The vacuum pump 93 draws air through the air guide pipe 95 and transports it to the air guide metal plate 96. The air is changed by the surface temperature 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 emission of the electric heating tube 97 according to the signal fed back by the temperature sensor 913. Thermal power, so that the temperature of the air entering the intake pipe 910 is in the range of -10 degrees Celsius to 50 degrees Celsius, and the ambient temperature in the shield 2 is increased by 5 degrees Celsius every time during the test, 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 of the wireless charging device, the charging performance under the dynamic environment of vehicle bumps and the maximum effective wireless charging distance at this temperature, and these test data are transmitted to the AI ​​large model pre-installed in the integrated 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 integrated computer 14 organizes 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;

[0055] In summary, the wireless charging test device can perform multi-faceted tests on randomly purchased wireless charging devices. It simulates the full wireless charging performance test of the wireless charging device at different temperatures through the temperature environment simulation mechanism 9, highly restores the actual use environment, and greatly improves the test accuracy. The test device also has the function of simulating wireless charging tests in static and vehicle-mounted dynamic environments. It simulates bumps through different speed modes to make up for the shortcomings of existing tests that lack dynamic scenes, making the test results richer. It can not only accurately test the performance of wireless charging devices, but also improve the reliability of the use of the test device. In addition, the test device uses the AI ​​large model to deeply analyze data and can quickly obtain accurate results, helping to determine whether the wireless charging device meets customer needs and improving the convenience and efficiency of wireless charging testing.
