[0040] First embodiment:

[0041] Please refer to Figures 7 to 10 In the first embodiment of the present invention, a load testing device is used to perform a load test on the auxiliary driving domain controller after it is assembled and formed. The load testing device includes: A test box 1, wherein a wire hole 101 is provided on the test box 1 to provide wire movement space for the wired connection between the docking plug set 72 and the load test box 5; A conveying device 2, wherein the conveying device 2 is installed on the test chassis 1; A display alarm device 3, wherein the display alarm device 3 is integrated and mounted on the test chassis 1; A visual recognition device 4, wherein the visual recognition device 4 is installed on the top of the test chassis 1; A load test box 5, wherein the load test box 5 is integrated and installed at the bottom of the test chassis 1; The plug device 7 includes a telescopic member 71 and a docking plug group 72. Both ends of the telescopic member 71 are fixedly connected to the test box 1 and the docking plug group 72. The docking plug group 72 is connected to the load test box 5 by wire, and the cable has a loose range to provide support for the movement and adjustment of the docking plug group 72. The positioning device 6 comprises a slide 61, a positioning frame 62 and a sliding shaft 63. The sliding shaft 63 passes through one end of the slide 61 and is fixedly mounted on the test chassis 1. The other end of the slide 61 is fixedly connected to the positioning frame 62. The positioning frame 62 is provided with a positioning hole 621. A spring retractable tube 8, two ends of which are respectively hinged to the docking plug set 72 and the slide 61; Among them, a domain controller 100 to be tested is installed on the conveying device 2, and the port of the domain controller 100 to be tested is facing the moving range of the docking plug group 72.

[0042] When the domain controller 100 to be tested is installed on the conveying device 2, the port of the domain controller 100 to be tested should be ensured to move within the range of the docking plug group 72, and the domain controller 100 to be tested should be located in the middle of the conveying device 2, so that the domain controller 100 to be tested can be stably transported to the bottom of the positioning frame 62, and the conveying device 2 cooperates with the visual recognition device 4 to accurately position the domain controller 100 to be tested.

[0043] The visual recognition device 4 uses an infrared high-definition camera to identify, locate and monitor the temperature of the domain controller 100 to be tested transported by the transport device 2.

[0044] The load test box 5 is respectively connected to the display alarm device 3, the visual recognition device 4, the telescopic part 71 and the docking plug group 72 by signals; the load test box 5 has a built-in load test assembly of the domain controller, which is used to perform a simulation test on the domain controller 100 to be tested after being connected, and perform standard tests on the domain controller 100 to be tested in sequence according to the requirements of the test items, and can identify and analyze the test results, and the analysis results are displayed as data and alarm information through the display alarm device 3.

[0045] In this embodiment, the docking plug set 72 includes two usage states: In the avoidance state, the docking plug group 72 is separated from the port of the domain controller 100 to be tested, and the positioning frame 62 is separated from the domain controller 100 to be tested, providing avoidance support for the tested domain controller 100 to continue to be transported; In the plugged state, the docking plug group 72 is plugged into the port of the domain controller 100 to be tested, and the positioning frame 62 is abutted and locked with the domain controller 100 to be tested, providing a locking limit function for the domain controller 100 to be tested, and providing support for the plugging limit between the docking plug group 72 and the domain controller 100 to be tested.

[0046] First, the domain controller 100 to be tested is installed on the conveying device 2, and the domain controller 100 to be tested is conveyed to the bottom of the positioning frame 62 by the conveying device 2, so that the domain controller 100 to be tested is moved to the test range; the conveying device 2 is closed, and the telescopic member 71 is started, and the telescopic member 71 drives the docking plug group 72 to move toward the domain controller 100 to be tested; While the docking plug group 72 moves, the docking plug group 72 first drives the slide 61 to move downward through the spring contraction tube 8, and the slide 61 drives the positioning frame 62 to move downward, so that the positioning frame 62 stably abuts against the top of the domain controller 100 to be tested through the positioning hole 621, thereby achieving locking and limiting of the domain controller 100 to be tested; After the domain controller 100 to be tested is locked and limited, the docking plug set 72 can continue to move and be inserted into the port of the domain controller 100 to be tested, so as to facilitate the automatic plugging between the docking plug set 72 and the domain controller 100 to be tested; Finally, during the process of plugging the docking plug group 72 and the domain controller to be tested 100, the locking limit of the domain controller to be tested 100 is simultaneously achieved; while satisfying the visual positioning, the automatic locking limit and automatic plugging of the domain controller to be tested 100 are achieved, reducing manual operations and meeting the needs of equipment automation control and management.

[0047] Preferably, Fig. 9 As shown, the conveying device 2 includes a motor 21, two conveying rollers 22 and a conveyor belt 23. The motor 21 is fixed on the test box 1. The conveying rollers 22 penetrate the test box 1 and are fixedly connected to the driving shaft of the motor 21. The conveyor belt 23 is transmission-connected to the two conveying rollers 22.

[0048] The motor 21 provides power for the rotation adjustment of one of the conveying rollers 22. During the rotation of one of the conveying rollers 22, the conveying belt 23 synchronously drives the other conveying roller 22 to rotate. During the rotation and transmission of the conveying belt 23, it is convenient to transport the domain controller 100 to be tested placed above the conveying belt 23.

[0049] Preferably, Fig.10 As shown, a pressure sensor 622 is embedded and installed on the positioning frame 62 . When the positioning frame 62 is in a downwardly pressed positioning state, the pressure sensor 622 abuts against and aligns with the moving range of the docking plug assembly 72 .

[0050] In this embodiment, the pressure sensor 622 is signal-connected to the load test box 5. When the pressure sensor 622 detects a pressure signal, the load test box 5 starts the test project and automatically performs intelligent load test analysis on the domain controller 100 to be tested that is plugged in.

[0051] When the docking plug group 72 is fully adjusted to the plug-in state, the docking plug group 72 abuts against the pressure sensor 622, so that the pressure sensor 622 detects that the docking plug group 72 is plugged in place; this facilitates the feedback of the position information of the docking plug group 72 when plugged in, and provides signal support for the self-starting of the load test of the equipment.

[0052] The pressure sensor 622 is used to detect whether the docking plug group 72 is aligned when adjusted to the plug-in state, thereby ensuring the stability of the plug-in load test between the docking plug group 72 and the domain controller 100 to be tested.

[0053] The working principle of the load testing device provided in this embodiment is as follows: like Fig.11 As shown in (a), it may be defined that in the initial state, the docking plug set 72 is in an avoidance state, the positioning frame 62 is lifted up to provide avoidance for the transportation of the domain controller 100 to be tested, and the spring contraction pipe 8 is in a fully contracted state; Please refer to Fig.11 (a) to Fig.11 (b) to Fig.11 (c) in which, when the visual recognition device 4 recognizes that the domain controller 100 to be tested is transported to the test range, the motor 21 is turned off, and the telescopic member 71 is started, and the telescopic member 71 drives the docking plug group 72 to move toward the port of the domain controller 100 to be tested and plugged in; Before plugging, when the docking plug group 72 moves, the spring contraction tube 8 drives the slide 61 to move downward, and when the slide 61 moves downward, the positioning frame 62 is driven downward, so that the positioning frame 62 moves downward through the positioning hole 621 and is locked on the top of the domain controller 100 to be tested, thereby realizing the locking limit of the domain controller 100 to be tested before plugging; After being locked, the slide 61 cannot move downward, and the spring contraction tube 8 provides elastic support for the continued movement and insertion of the docking plug set 72, so that the docking plug set 72 can be stably plugged with the locked and limited domain controller 100 to be tested; After plugging, the docking plug set 72 abuts against the pressure sensor 622, and the pressure sensor 622 feeds back a signal to the load test box 5, and the load test box 5 starts and automatically controls the operation of the load test program to automatically identify and load test the domain controller 100 to be tested; like Fig.11 As shown in (c), the docking plug set 72 is in a plugged-in state, the positioning frame 62 is pressed down to provide a locking limit for the automatic plugging of the domain controller 100 to be tested, and the spring contraction tube 8 is in an elastically stretched state.

[0054] Ultimately, under the driving action of the telescopic member 71, the locking limit of the domain controller to be tested 100 and the automatic connection between the docking plug group 72 and the domain controller to be tested 100 are simultaneously achieved; while satisfying the visual positioning, the automatic locking limit and automatic connection of the domain controller to be tested 100 are achieved, reducing manual operations and meeting the needs of equipment automation control and management.

The two ends of the supporting tube 932 are fixedly connected to the rotating box 931 and one end of the pressure shaft 933, and the other end of the pressure shaft 933 passes through the rotating box 931. The two ends of the transmission rod 935 are hinged to the pressure shaft 933 and the transmission protrusion 934, and the transmission protrusion 934 passes through the rotating box 931 and is slidably connected. One end of the pushing frame 94 is fixed to the bottom of the docking plug group 72, and the other end of the pushing frame 94 is aligned with the telescopic range of the pressure shaft 933.

[0061] In this embodiment, the transmission protrusion 934 includes two use states: like Fig.14 As shown in (a), in the disc state, the transmission protrusion 934 is completely retracted in the rotating box 931, so that when the rotating box 931 rotates, the transmission protrusion 934 will not contact the conveyor belt 23, which facilitates maintaining the stability of the conveyor belt 23 driving the domain controller 100 to be tested; like Fig.14 As shown in (c), in the cam state, the transmission protrusion 934 protrudes from the rotating box 931, so that a cam structure is formed between the transmission protrusion 934 and the rotating box 931, and the protruding range is aligned with the conveying range of the conveyor belt 23. During the rotation of the cam structure, the conveyor belt 23 and the domain controller 100 to be tested during the load test can be pushed up and down in a small amplitude and intermittent manner, thereby providing a vibration test environment for the domain controller 100 to be tested during the load test, which is convenient for simulating real application scenarios.

[0062] When the domain controller 100 to be tested is adjusted for conveying, the motor 21 rotates and conveys through the conveying roller 22 and the conveying belt 23, so as to provide power for the conveying of the domain controller 100 to be tested; at the same time, the motor 21 drives the rotating shaft 92 to rotate through the synchronizing member 91, so that the rotating shaft 92 drives the rotating box 931 and the transmission protrusion 934 in the disc state to rotate synchronously, so as to maintain the stability of the rotating conveying of the conveying belt 23.

[0063] During the load test of the domain controller 100 to be tested, the motor 21 can drive the conveyor belt 23 to transport and adjust, and the motor 21 can also drive the rotating shaft 92 to rotate through the synchronous member 91, so that the rotating shaft 92 drives the rotating box 931 and the transmission protrusion 934 in the cam state to rotate synchronously, so that the transmission protrusion 934 rotates while providing a power source for up and down vibration for the domain controller 100 to be tested through the conveyor belt 23, so as to facilitate the simultaneous realization of environmental testing requirements of the vibration environment during the load test.

[0064] Finally, in the process of the docking plug assembly 72 switching from the avoidance state to the plugging state, the downward positioning of the slide 61 and the adaptive adjustment of the state of the transmission protrusion 934 are achieved.

[0065] In an optional implementation of this embodiment, the synchronous member 91 may be a pulley structure, which includes two pulleys and a belt, one pulley being fixedly connected to the drive shaft of the motor 21, and the other pulley being fixedly connected to the rotating shaft 92, and the belt transmission connecting the two pulleys. This allows the rotating shaft 92 to be driven to rotate by the synchronous member 91 while the drive shaft of the motor 21 is rotated and adjusted, thereby providing power for the rotation adjustment of the rotating box 931.

[0066] In another optional implementation of this embodiment, the synchronous member 91 may be a sprocket group structure, which includes two sprockets and a chain, one sprocket is fixedly connected to the drive shaft of the motor 21, and the other sprocket is fixedly connected to the rotating shaft 92, and the chain transmission connects the two sprockets. When the drive shaft of the motor 21 is rotated and adjusted, the rotating shaft 92 can also be driven to rotate through the synchronous member 91, providing power for the rotation adjustment of the rotating box 931.

[0067] The working principle of the load testing device provided in this embodiment is as follows: like Fig.12 and Fig.14 As shown in (a), when the docking plug assembly 72 is in the avoidance state, the pushing frame 94 and the pressure shaft 933 are in a separated state, and the transmission protrusion 934 is in a disc state; Please refer to Fig.14 (a) to Fig.14 (b) to Fig.14 In (c), during the process of the docking plug assembly 72 switching from the avoidance state to the plugging state, the docking plug assembly 72 synchronously drives the pushing frame 94 to move toward the pressure shaft 933; When the pushing frame 94 moves and abuts against the pressure shaft 933, the pressure shaft 933 is compressed and retracted into the rotating box 931. While the pressure shaft 933 is retracted, the transmission protrusion 934 is pushed to extend by the transmission rod 935, so that the transmission protrusion 934 extends out of the rotating box 931, so that the docking plug assembly 72 is adjusted to the plug-in state and the transmission protrusion 934 is switched to the cam state. like Fig.14 As shown in (c), when the docking plug assembly 72 is in the plugged state, the push frame 94 and the pressure shaft 933 are in abutment state, the transmission protrusion 934 is in a cam state, and the pressure shaft 933 is allowed to rotate and adjust relative to the push frame 94; In the plugged state, the domain controller 100 to be tested is limited by the positioning frame 62 and the docking plug group 72, and the conveyor belt 23 can slide relative to the domain controller 100 to be tested, without affecting the load test. While the motor 21 drives the conveyor belt 23 to continue rotating and conveying, the motor 21 also drives the rotating shaft 92 to rotate and adjust through the synchronous member 91. The rotating shaft 92 rotates and drives the rotating box 931 and the transmission protrusion 934 in the cam state to rotate and adjust. During the rotation of the transmission protrusion 934, an upward driving force is intermittently applied to the conveyor belt 23, so that the conveyor belt 23 fluctuates up and down uninterruptedly, providing the environmental requirements of the vibration test for the domain controller 100 to be tested during the load test. Finally, in the process of the docking plug assembly 72 switching from the avoidance state to the plugging state, the downward positioning of the slide 61 and the adaptive adjustment of the state of the transmission protrusion 934 are achieved.

[0068] The invention also provides a testing system.

[0069] The test system uses the load test device to perform load test on the assembled auxiliary driving domain controller. Specifically, the test system includes: a visual recognition module, an intelligent management module, a load test module, an intelligent alarm module and a joint docking module; The visual recognition module monitors in real time whether the domain controller 100 to be tested reaches the test range; The intelligent management module is used to control the connection between the joint docking module and the domain controller 100 to be tested according to the monitoring result of the visual recognition module; The load testing module is used to perform load operation on the connected domain controller to be tested 100; The intelligent alarm module automatically identifies and alarms according to the load test results; The connector docking module is used to drive the connection and separation of the connector of the load test module and the port of the domain controller 100 to be tested; During the load test of the domain controller 100 to be tested, the visual recognition module continues to monitor the temperature distribution of the domain controller 100 to be tested, and monitors the temperature changes during the load test of the domain controller in real time.

[0070] Ultimately, it is possible to realize intelligent identification, precise positioning, temperature monitoring, automatic plug-in, automatic load testing, and automatic alarm of the domain controller 100 to be tested, so as to facilitate the intelligent management of the load test of the domain controller 100 to be tested, reduce manual intervention, and facilitate intelligent load detection during the mass production process of the domain controller 100 to be tested.
