DETAILED DESCRIPTION

[0022] Below, the present invention is further described in conjunction with the accompanying drawings and specific embodiments:

[0023] like Figure 1-4 A new energy vehicle fault diagnosis teaching test bench shown includes a workbench 10, a detection assembly 20, a support assembly 40 and a first driving mechanism. Specifically, the detection assembly 20 includes a detection frame 21, a detection probe 22 and a second driving mechanism. The detection frame 21 is installed on the workbench 10. Driven by the first driving mechanism, the detection frame 21 can move along the length direction of the workbench 10. The detection probe 22 is installed on the detection frame 21. Driven by the second driving mechanism, the detection frame 21 can move along the height direction of the detection frame 21.

[0024] In addition, the support assembly 40 is installed on the workbench 10 . The support assembly 40 is used to support the workpiece. The support assembly 40 can drive the workpiece to rotate toward or away from the detection assembly 20 .

[0025] On the basis of the above structure, when using the new energy vehicle fault diagnosis teaching test bench of the present invention, the power battery to be repaired can be placed on the support assembly 40 on the workbench 10, and the power line of the power motor can be connected to the external circuit. When performing fault diagnosis, the first drive mechanism can be started to drive the detection frame 21 to move above the maintenance line of the power battery, and then the second drive mechanism can drive the detection probe 22 to move downward. In this way, the detection probe 22 on the detection frame 21 can detect different lines of the power battery and perform fault diagnosis; and the detection frame 21 can move under the drive of the first drive mechanism, so that fault diagnosis can be performed in sections. At the same time, the height of the detection probe 22 can be flexibly adjusted under the drive of the second drive mechanism. In addition, the support assembly can drive the power battery to rotate, adjust the detection angle, and automatically perform fault detection, which is convenient for on-site teaching.

[0026] Of course, the detection probe 22 can be implemented by using a probe used for circuit fault diagnosis in the prior art.

[0027] Preferably, in this embodiment, the support assembly 40 includes a base 41, a support platform 42 and a connecting arm 43. The base 41 is fixed to the workbench 10 by screws, and one end of the support platform 42 is hinged to one end of the base 41; the other end of the base 41 is screwed with a bolt 411; one end of the connecting arm 43 can be hinged to the other end of the support platform 42. Specifically, a slide groove 431 is provided at the other end of the connecting arm 43; the slide groove 431 extends along the length direction of the connecting arm 43; the bolt 411 is inserted into the slide groove 431 and can slide along the slide groove 431; and a plurality of mounting holes are provided on the supporting platform 42.

[0028] When installing the power battery, the power battery can be fixed in the multiple installation holes on the support platform 42 by screws. When the power battery needs to be rotated, the support seat can be rotated relative to the base 41. When it is rotated to a required angle, the bolt 411 can be tightened to fix the connecting arm 43, so that the support platform 42 is fixed relative to the base 41. Of course, when adjusting again, the bolt 411 is loosened, and the bolt 411 can slide in the slide groove 431, so that the support platform 42 can be rotated.

[0029] Preferably, abutment blocks 11 may be hinged on both sides of the workbench 10, and the abutment blocks 11 may rotate toward or away from the end surface of the workbench 10, and the support assembly 40 is located between the two abutment blocks 11. In this way, when the power battery is in a horizontal state for fault diagnosis, the peripheral edge of the shell of the power battery may be located between the abutment block 11 and the end surface of the workbench 10, and the abutment block 11 may rotate toward the workbench 10 and abut against the shell of the power battery, thereby further stabilizing the installation structure of the power battery.

[0030] It should be noted that the abutment block 11 can be hinged to the workbench 10 via a hinge in the prior art.

[0031] Preferably, a mounting seat 24 may be provided on the detection frame 21, and the detection probe 22 may be installed on the mounting seat 24. The mounting seat 24 and the top of the detection frame 21 are directly connected with a spring 23. In this way, the spring 23 can maintain a certain floating space between the detection probe 22 and the circuit to be detected, thereby playing a certain buffering role and preventing the detection probe 22 from directly colliding with the power battery housing during movement.

[0032] Preferably, in this embodiment, the second driving mechanism includes a driving cylinder, the cylinder body of the driving cylinder is fixed to the detection frame 21; the piston rod of the driving cylinder is fixed to the mounting seat 24; a slider is provided on the mounting seat 24; a slide rail is provided on the detection frame 21; the slider and the slide rail are slidably matched, so that the piston rod of the driving cylinder can be extended and retracted to drive the mounting seat 24 to move up and down, thereby driving the detection probe 22 on the mounting seat 24 to move up and down. The sliding match between the slider and the slide rail can guide the mounting seat 24 up and down, and the movement process is more stable, preventing the detection probe 22 from deviating during detection.

[0033] Furthermore, a detection light 25 may be fixedly connected to the mounting base 24 , and the detection light 25 may be used for lighting during the detection of the probe 22 , so that the inspection field of view is clearer.

[0034] Preferably, the first driving mechanism includes an electric slide 30, and the detection frame 21 is fixedly connected to the slide of the electric slide 30. The electric slide 30 can be purchased from the market. The movement of the electric slide 30 can drive the detection frame 21 to reciprocate, and the structure is simple and stable.

[0035] Furthermore, the new energy vehicle fault diagnosis teaching test bench also includes a frame 100, a mounting frame 70 and a third driving mechanism 60. The mounting frame 70 is pivotally connected to the frame 100. Specifically, the third driving mechanism 60 is used to drive the mounting frame 70 to rotate, and the workbench 10 is fixed to the bottom end of the mounting frame 70; the top end of the mounting frame 70 is rotatably installed with a clamping assembly 50, and the clamping assembly 50 is used to clamp the camera 54.

[0036] Based on the above structure, when fault diagnosis is performed on the workbench 10, the mounting frame 70 can be driven to rotate by the third driving mechanism 60, so that the diagnosis process can be displayed in multiple directions, which is convenient for teaching. In addition, the camera 54 provided on the top of the mounting frame 70 can shoot the diagnosis process on the workbench 10, and the shooting results can be stored for later teaching. Since the clamping assembly 50 can rotate, it can drive the camera 54 to rotate, which is convenient for shooting from multiple angles.

[0037] Furthermore, the clamping assembly 50 includes two clamps 52 and a clamp motor 51. The two clamps 52 are respectively mounted on both sides of the top of the mounting frame 70. The clamp motor 51 is used to drive the clamps 52 to rotate, and a mounting plate 53 is clamped between the two clamps 52. Specifically, a plurality of cameras 54 and a display screen are provided on the mounting plate 53. The plurality of cameras 54 are used to shoot the workbench 10 and transmit image signals; and the display screen is used to receive image signals.

[0038] In this way, two clamps 52 can be used to clamp the two ends of the mounting plate 53 respectively, and the diagnostic process on the workbench 10 can be photographed through multiple cameras 54, so that the shooting field of view is more comprehensive. In addition, the captured image signal can be directly received by the display screen for display, and the teaching is more intuitive. Driven by the clamp motor 51, the mounting plate 53 can rotate, thereby driving the camera 54 and the display screen to rotate together, and both the shooting and the display can be adjusted. In addition, the above-mentioned clamp 52 can be selected as a pneumatic finger in the prior art.

[0039] Furthermore, the mounting plate 53 has a plurality of connection holes, which can be connected to an external pipe, and the pipe can introduce air flow or water flow to clean the workbench 10. Of course, in the absence of the mounting plate 53, the clamping assembly 50 can directly clamp the external water pipe to clean the workbench 10.

[0040] Furthermore, the third driving mechanism 60 includes a motor, a transmission shaft 63, a first bevel gear 61 and a second bevel gear 62. The motor body is fixedly connected to the frame 100. The first bevel gear 61 is fixedly connected to the rotating shaft of the motor. The second bevel gear 62 is meshed with the first bevel gear 61. The transmission shaft 63 is fixedly connected to the second bevel gear 62. The mounting frame 70 is fixedly connected to the top of the transmission shaft 63. In this way, when the mounting frame 70 is driven to rotate, the motor can be started, the rotation of the rotating shaft of the motor can drive the first bevel gear 61 to rotate, the rotation of the first bevel gear 61 can drive the second bevel gear 62 meshed therewith to rotate, and the rotation of the second bevel gear 62 can drive the transmission shaft 63 to rotate, thereby driving the mounting frame 70 to rotate, and the transmission accuracy is high.

[0041] For those skilled in the art, various other corresponding changes and deformations can be made according to the technical solutions and concepts described above, and all of these changes and deformations should fall within the protection scope of the claims of the present invention.
