[0095] The present invention also provides a load testing device.

[0096] First Embodiment:

[0097] Please refer to Figures 7 to 10 , in the first embodiment of the present invention, the load testing device is used for load testing after the assembled assisted driving domain controller. The load testing device includes:

[0098] A test chassis 1, on which a wire hole 101 is opened to provide a wire movement space for the wired connection between the docking plug group 72 and the load testing box 5;

[0099] A conveying device 2, which is installed on the test chassis 1;

[0100] A display and alarm device 3, which is integrally installed on the test chassis 1;

[0101] A visual recognition device 4, which is installed on the top of the test chassis 1;

[0102] A load testing box 5, which is integrally installed at the bottom of the test chassis 1;

[0103] A plugging device 7, which includes a telescopic member 71 and a docking plug group 72. The two ends of the telescopic member 71 are fixedly connected to the test chassis 1 and the docking plug group 72 respectively. The docking plug group 72 is wired-connected to the load testing box 5, and the cable is reserved with a loose range to provide support for the movement and adjustment of the docking plug group 72;

[0104] Positioning device 6, the positioning device 6 includes a carriage 61, a positioning frame 62 and a sliding shaft 63. The sliding shaft 63 passes through one end of the carriage 61 and is fixed on the test chassis 1. The other end of the carriage 61 is fixedly connected to the positioning frame 62, and a positioning hole 621 is provided on the positioning frame 62;

[0105] Spring contraction pipe fitting 8, both ends of the spring contraction pipe fitting 8 are respectively hinged to the docking plug group 72 and the carriage 61;

[0106] Among them, a to-be-tested domain controller 100 is installed on the conveying device 2, and the port of the to-be-tested domain controller 100 faces the moving range of the docking plug group 72.

[0107] When the to-be-tested domain controller 100 is installed on the conveying device 2, it should be ensured that the port of the to-be-tested domain controller 100 faces the moving range of the docking plug group 72, and the to-be-tested domain controller 100 is located in the middle of the conveying device 2, so that the to-be-tested domain controller 100 can be stably conveyed to directly below the positioning frame 62. The conveying device 2 cooperates with the visual recognition device 4 to perform precise positioning on the to-be-tested domain controller 100.

[0108] The visual recognition device 4 uses an infrared high-definition camera to, on the one hand, identify, position and monitor the temperature of the to-be-tested domain controller 100 conveyed on the conveying device 2.

[0109] The load test box 5 is respectively signal-connected to the display and alarm device 3, the visual recognition device 4, the telescopic member 71 and the docking plug group 72; the load test box 5 internally contains a load test assembly of the domain controller, which is used to perform a simulation test after being connected to the to-be-tested domain controller 100, perform a standard test on the to-be-tested domain controller 100 in sequence according to the test item requirements, and can identify and analyze the test results. The analysis results are displayed through the display and alarm device 3 for data and alarm information.

[0110] In this embodiment, the docking plug group 72 includes two usage states:

[0111] Avoidance state, the docking plug group 72 is separated from the port of the to-be-tested domain controller 100, and the positioning frame 62 is separated from the to-be-tested domain controller 100, providing an avoidance support for the to-be-tested domain controller 100 after the test to continue conveying;

[0112] Plugging state, the docking plug group 72 is plugged into the port of the to-be-tested domain controller 100, and the positioning frame 62 abuts against and locks the to-be-tested domain controller 100, providing a locking and limiting function for the to-be-tested domain controller 100 and providing a plugging and limiting support between the docking plug group 72 and the to-be-tested domain controller 100.

[0113] First, install the domain controller 100 to be tested on the conveying device 2. Through the conveying device 2, convey the domain controller 100 to be tested to directly below the positioning frame 62, so that the domain controller 100 to be tested moves into the test range; close the conveying device 2 and start the telescopic member 71. The telescopic member 71 drives the docking plug group 72 to move towards the domain controller 100 to be tested;

[0114] While the docking plug group 72 is moving, the docking plug group 72 first drives the sliding frame 61 to move downward through the spring contraction pipe fitting 8, and the sliding frame 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, realizing the locking and limiting of the domain controller 100 to be tested;

[0115] After the domain controller 100 to be tested is locked and limited, the docking plug group 72 can continue to move and insert into the port of the domain controller 100 to be tested, facilitating the automatic plugging between the docking plug group 72 and the domain controller 100 to be tested;

[0116] Finally, during the process of plugging the docking plug group 72 and the domain controller 100 to be tested, the locking and limiting of the domain controller 100 to be tested are synchronously realized; while meeting visual positioning, the automatic locking and limiting and automatic plugging of the domain controller 100 to be tested are realized, reducing manual operations and meeting the requirements of equipment automation control and management.

[0117] Preferably, as Figure 9 shown, the conveying device 2 includes a motor 21, two conveying rollers 22 and a conveyor belt 23. The motor 21 is fixedly arranged on the test chassis 1. The conveying roller 22 penetrates through the test chassis 1 and is fixedly connected to the drive shaft of the motor 21. The conveyor belt 23 is drivingly connected to the two conveying rollers 22.

[0118] 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 other conveying roller 22 is synchronously driven to rotate through the conveyor belt 23. During the rotation and transmission of the conveyor belt 23, it is convenient to convey the domain controller 100 to be tested placed above the conveyor belt 23.

[0119] Preferably, as Figure 10 shown, a pressure sensor 622 is inlaid and installed on the positioning frame 62. When the positioning frame 62 is in the downward pressing and positioning state, the pressure sensor 622 abuts and aligns within the moving range of the docking plug group 72.

[0120] 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.

[0121] 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.

[0122] 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.

[0123] The working principle of the load testing device provided in this embodiment is as follows:

[0124] like Figure 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;

[0125] Please refer to Figure 11 (a) to Figure 11 (b) to Figure 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;

[0126] 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;

[0127] 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;

[0128] After insertion, 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. The load test box 5 starts and automatically controls the operation of the load test program to automatically identify and perform a load test on the to-be-tested domain controller 100;

[0129] As Figure 11 shown in (c) of [], the docking plug set 72 is in an inserted state, the positioning frame 62 presses down to provide locking and limiting for the automatic insertion of the to-be-tested domain controller 100, and the spring contraction pipe fitting 8 is in an elastically extended state.

[0130] Finally, under the driving action of one telescopic member 71, the locking and limiting of the to-be-tested domain controller 100 and the automatic insertion of the docking plug set 72 and the to-be-tested domain controller 100 are synchronously realized; while meeting visual positioning, the automatic locking and limiting and automatic insertion of the to-be-tested domain controller 100 are realized, reducing manual operations and meeting the requirements of equipment automatic control and management.

[0131] Second Embodiment:

[0132] Please refer to Figure 12 , based on a load test device provided by the first embodiment of the present invention, the second embodiment of the present invention proposes another load test device. The second embodiment is only a preferred manner of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0133] Specifically, the difference of the load test device provided by the second embodiment of the present invention is that the load test device further includes a vibration device 9, and the vibration device 9 is installed at the bottom of the moving range of the conveyor belt 23 to provide a vibration source during the load test of the conveyor belt 23.

[0134] A vibration device 9 is arranged within the range of the conveyor belt 23, which is convenient for providing the power for the conveyor belt 23 to vibrate up and down, so as to conveniently provide a vibration test environment during the load test of the to-be-tested domain controller 100, so as to simulate a real use scenario (the vibration amplitude will not affect the stability of equipment insertion).

[0135] In an alternative embodiment of this embodiment, the vibration device 9 adopts an independent vibration motor and a cam. The vibration motor is fixedly arranged in the test chassis 1, the cam is installed on the drive shaft of the vibration motor, and the vibration motor can drive the cam to rotate and adjust. The cam is aligned within the conveying range of the conveyor belt 23; when the cam rotates, it can drive the conveying surface of the conveyor belt 23 to undulate up and down to form a vibration test environment.

[0136] In another alternative embodiment of this embodiment, please refer to and combineFigure 11 , Figure 12 and Figure 14 in (a) thereof, the vibration device 9 includes a synchronizing member 91, a rotating shaft 92, a vibration head 93 and a pushing frame 94. One end of the rotating shaft 92 is rotatably installed on the test chassis 1. The synchronizing member 91 is in transmission connection with the driving shaft of the motor 21 and the rotating shaft 92. The vibration head 93 includes a rotating box 931, a spring support pipe fitting 932, a pressure-receiving shaft 933, a transmission convex block 934 and a transmission rod 935. One end of the rotating box 931 is fixedly arranged at the other end of the rotating shaft 92. Both ends of the spring support pipe fitting 932 are fixedly connected to the rotating box 931 and one end of the pressure-receiving shaft 933. The other end of the pressure-receiving shaft 933 penetrates through the rotating box 931. Both ends of the transmission rod 935 are hinged to the pressure-receiving shaft 933 and the transmission convex block 934. The transmission convex block 934 penetrates through the rotating box 931 and is in sliding connection therewith. One end of the pushing frame 94 is fixedly arranged at the bottom of the docking plug group 72, and the other end of the pushing frame 94 is aligned within the telescopic range of the pressure-receiving shaft 933.

[0137] In this embodiment, the transmission convex block 934 has two usage states:

[0138] As Figure 14 shown in (a) thereof, in the disk state, the transmission convex block 934 is completely retracted into the rotating box 931, so that when the rotating box 931 rotates, the transmission convex block 934 will not come into contact with the conveyor belt 23, facilitating the maintenance of the stability of the conveyor belt 23 to drive the conveyance of the device under test controller 100.

[0139] As Figure 14 shown in (c) thereof, in the cam state, the transmission convex block 934 protrudes from the rotating box 931, so that a cam structure is formed between the transmission convex block 934 and the rotating box 931, and the protruding range is aligned within the conveyance range of the conveyor belt 23. During the rotation of this cam structure, the conveyor belt 23 and the device under test controller 100 during the load test can be pushed to move up and down in a small amplitude and intermittently, thereby providing a vibration test environment for the device under test controller 100 during the load test and facilitating the simulation of a real application scenario.

[0140] When the conveyance of the device under test controller 100 is adjusted, the motor 21 rotates and conveys through the conveying roller 22 and the conveyor belt 23 to provide power for the conveyance of the device under test controller 100. 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 convex block 934 in the disk state to rotate synchronously, maintaining the stable rotation and conveyance of the conveyor belt 23.

[0141] During the load test of the domain controller 100 to be tested, while the motor 21 can drive the conveyor belt 23 to convey and adjust, the motor 21 can also drive 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 convex block 934 in the shape of a cam to rotate synchronously. While the transmission convex block 934 rotates, it provides the power source for the up-and-down vibration of the domain controller 100 to be tested through the conveyor belt 23, facilitating the synchronous realization of the environmental test requirements of the vibration environment during the load test.

[0142] Finally, during the process of the docking plug group 72 switching from the avoidance state to the plugging state, the downward positioning of the carriage 61 and the adaptive adjustment of the state of the transmission convex block 934 are realized.

[0143] In an alternative embodiment of the present embodiment, the synchronizing member 91 can be a pulley structure. The pulley structure includes two pulleys and a belt. One pulley is fixedly connected to the drive shaft of the motor 21, and the other pulley is fixedly connected to the rotating shaft 92. The belt is drivingly connected to the two pulleys. While the drive shaft of the motor 21 rotates and adjusts, it can also drive the rotating shaft 92 to rotate through the synchronizing member 91, providing power for the rotation adjustment of the rotating box 931.

[0144] In another alternative embodiment of the present embodiment, the synchronizing member 91 can be a sprocket group structure. The sprocket group structure 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. The chain is drivingly connected to the two sprockets. While the drive shaft of the motor 21 rotates and adjusts, it can also drive the rotating shaft 92 to rotate through the synchronizing member 91, providing power for the rotation adjustment of the rotating box 931.

[0145] The working principle of the load test device provided in this embodiment:

[0146] As Figure 12 and Figure 14 shown in (a) therein, when the docking plug group 72 is in the avoidance state, the push frame 94 and the pressure-receiving shaft 933 are in a separated state, and the transmission convex block 934 is in a disc state;

[0147] Please refer to Figure 14 from (a) to Figure 14 from (b) to Figure 14 from (c) therein. During the process of the docking plug group 72 switching from the avoidance state to the plugging state, the docking plug group 72 synchronously drives the push frame 94 to move towards the pressure-receiving shaft 933;

[0148] 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.

[0149] like Figure 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;

[0150] 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.

[0151] 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.

[0152] The invention also provides a testing system.

[0153] 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;

[0154] The visual recognition module monitors in real time whether the domain controller 100 to be tested reaches the test range;

[0155] 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;

[0156] The load testing module is used to perform load operation on the connected domain controller to be tested 100;

[0157] The intelligent alarm module automatically identifies and alarms according to the load test results;

[0158] 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;

[0159] During the load test of the domain controller 100 to be tested, the visual recognition module also continues to monitor the temperature distribution of the domain controller 100 to be tested, and real-time monitors the temperature change during the load test of the domain controller.

[0160] Finally, it is convenient to realize the intelligent identification, precise positioning, temperature monitoring, automatic plugging, automatic load test, 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 the intelligent load detection during the mass production process of the domain controller 100 to be tested.

[0161] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made by using the content of the specification and drawings of the present invention under the concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
