[0024] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0025] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0026] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0027] An automatic detection system for vehicle charging sockets, such as Figure 1 As shown, it mainly includes a CAN transceiver communication module 102, a programmable power control module 103, a product function detection module 101, a data storage and traceability module 104, and a lower-level machine control module 105.

[0028] The CAN transceiver communication module 102 is connected to the product function detection module 101 and the charging socket 30, respectively. It is used to control the power-on state of the charging socket 30 and transmit the working status signal of the charging socket 30 after power-on and the product information to the product function detection module 101. Specifically, in this embodiment, the CAN transceiver communication module 102 integrates the CANalyst-II analyzer product of Zhuhai Chuangxin Technology and performs secondary development to realize CAN communication between the host computer 20 and the charging socket 30 under test. It can realize functions such as product sleep and wake-up, product working voltage reading, version number information reading, unlocking and locking control, and temperature monitoring.

[0029] The programmable power control module 103 is connected to the product function detection module 101 and the charging socket 30, respectively, to provide the charging socket 30 with multiple power supply voltage levels. Furthermore, when the charging socket 30 operates under different power supply voltage levels, the CAN transceiver communication module 102 needs to transmit the working status signal of the charging socket 30 after power-on and product information to the product function detection module 101, thereby enabling the performance testing of the charging socket 30 under different power supply voltage levels. In this embodiment, the programmable power control module 103 integrates an ITECH programmable power supply to adjust the power supply voltage of the charging socket 30 under test. Specifically, the power supply voltage includes a 9-16V operating voltage, a 7.7V undervoltage test, and a 17V overvoltage test.

[0030] The data storage and traceability module 104 is connected to the product function testing module and is used to store the working status signal and product information of the charging socket 30 after it is powered on. It is used to record relevant information of each charging socket 30 product function test, so as to facilitate the traceability of product problems after it is launched on the market.

[0031] The product function detection module 101 is used to acquire external control commands and control the CAN transceiver communication module 102, the programmable power control module 103, and the data storage and traceability module 104 to perform corresponding actions. External control commands are generally issued by the host computer 20 connected to the product function detection module 101. The product function detection module 101 uploads the working status signals and product information acquired by the CAN transceiver communication module 102 to the host computer for display. Furthermore, a certain threshold can be preset in the product function detection module 101, and the acquired working status signals can be compared with the preset threshold. If the test is qualified, green is displayed on the host computer 20; if it is unqualified, red is displayed on the host computer 20. The relevant test information of the product can also be displayed in the status bar at the bottom of the host computer 20.

[0032] The automatic testing system of this utility model provides multiple power supply voltages to the charging socket 30 through the programmable power control module 103, controls the power-on state of the charging socket 30 through the CAN transceiver communication module 102, and transmits the working status signal of the charging socket 30 after power-on and product information to the product function testing module 101. Thus, it can realize the performance testing of the charging socket 30 under different power supply voltages to meet the automatic testing of various testing processes before the charging socket leaves the factory. It has the advantages of simple operation, rapid testing and high degree of automation.

[0033] In one embodiment, the product function detection module 101, the CAN transceiver communication module 102, the programmable power control module 103, the lower-level control module 105, and the data storage and traceability module 104 are integrated on the lower-level detection module 10. The lower-level detection module 10 also integrates several control buttons 106 connected to the product function detection module 101. The control terminals of the control buttons 106 are connected to the output terminals of the lower-level control module 105, and the input terminals of the lower-level control module 105 are connected to the product function detection module 101. The product function detection module 101 can drive the control buttons 106 to press and release through the lower-level control module 105 to realize the automatic control of the automatic detection system. It should be noted that control commands can also be manually sent to the product function detection module 101 by pressing the control buttons 106, thereby controlling other modules to perform corresponding operations through the product function detection module 101. However, in general, considering the convenience of detection, automated detection is usually adopted.

[0034] In one implementation, such as Figure 2 As shown, the charging socket 30 has a flip cover 301 on its outer side, which is controlled to close by a drive motor 304. The output end of the lower-level control module 105 is connected to the control end of the drive motor 304 so as to control the opening and closing of the flip cover 301 by rotating the drive motor 304.

[0035] The operating status signal and product information of the charging socket 30 after power-on are acquired by the monitoring module 302 built into the charging socket 30. The output of the monitoring module 302 is connected to the product function detection module 101 via the CAN transceiver communication module 102. Here, the monitoring module 302 is generally an ECU module connected to temperature and voltage detection components. The ECU module transmits the monitored operating voltage and operating temperature signals to the product function detection module 101 through the temperature and voltage detection components. The charging socket 30 is also equipped with an electronic lock 303, which is connected to the product function detection module 101 via the CAN transceiver communication module 102 to control the locking and unlocking of the charging socket 30.

[0036] The detection process of this automatic detection system is as follows:

[0037] (1) The host computer 20 and the product function detection module 101 wake up the charging socket 30 under test through the CAN transceiver communication module 102 and control it to unlock.

[0038] (2) The product function detection module 101 opens the flip cover 301 through the lower computer control module 105 and the drive motor 304, and drives the corresponding control buttons 106 to press down (other buttons pop up) in sequence. The charging socket 30 will work for a period of time under different power supply voltages. The CAN transceiver communication module 102 obtains the working status signal and product information of the charging socket 30 after power-on under different power supply voltages and transmits them to the product function detection module 101.

[0039] (3) The product function detection module 101 uploads the working status signal and product information of the charging socket 30 after power-on under different power supply voltage levels to the host computer 20 for display.
