DETAILED DESCRIPTION

[0022] The present invention provides a device for testing the strength of a lightweight composite support plate for an automobile. Figure 1-4 As shown, it includes a test platform 11, a composite support plate 12, a first slot 13, a second slot 14, a third slot 15, a first rotating shaft 16, a second rotating shaft 17, a third rotating shaft 18, a first rotating disk 20, a second rotating disk 21, a third rotating disk 22, a test slot 25, a first baffle 26, a second baffle 27, a fourth slot 30, a first slider 31, a spring 32, an active contact 33, and a passive contact 34.

[0023] like Figure 1-4 As shown, the test platform 11 is provided with a first slot 13, a second slot 14 and a third slot 15, the first slot 13 is rotatably connected to the first rotating shaft 16, the second slot 14 is rotatably connected to the second rotating shaft 17, the third slot 15 is rotatably connected to the third rotating shaft 18, the second rotating shaft 17 and the third rotating shaft 18 are respectively fixedly connected to 23 and 24, and test slots 25 are provided on 23 and 24, the composite support plate 12 is clamped in the test slot 25, the first rotating disk 20 is fixedly connected to the first rotating shaft 16, the first rotating disk 20 is engaged with 23 and 24 respectively, and a sensing component is provided in the first rotating disk 20.

[0024] It is worth noting that the test platform 11 has a built-in driving power supply, which is used to drive the first rotating shaft 16 to rotate. The diameter of the first rotating disk 20 is smaller than the diameters of 23 and 24, and the diameter of 23 is equal to the diameter of 24.

[0025] The sensing component includes a first slider 31 and a spring 32, and a fourth slot 30 is provided on a side of the first rotating disk 20 close to the composite support plate 12. The first slider 31 is slidably connected to the fourth slot 30, one end of the spring 32 is fixedly connected to the first slider 31, and the other end of the spring 32 is fixedly connected to the fourth slot 30. A chamfer is provided on an end surface of the first slider 31 close to the composite support plate 12.

[0026] An active contact 33 is fixedly connected to one end face of the first slider 31 close to the spring 32, and a passive contact 34 is fixedly connected to one end face of the fourth slot 30 connected to the spring 32. The active contact 33 is electrically connected to the passive contact 34, and the passive contact 34 is externally connected to a display end. When the active contact 33 is in contact with the passive contact 34, the display end shows that the composite support plate 12 is not broken, and the display end synchronously displays the torque generated by the first rotating disk 20 driven by the first rotating shaft 16 on the second rotating disk 21 and the third rotating disk 22. Both sides of the first slot 13 are fixedly connected to the first baffle 26, and the first baffle 26 is fixedly connected to the second baffle 27. The first baffle 26 and the second baffle 27 are both made of steel.

[0027] When this scheme is used to test the strength of a lightweight composite support plate for an automobile, first, the two ends of the composite support plate 12 are placed on the test slots 23 and 24 respectively. At this time, the composite support plate 12 pushes the first slider 31 into the fourth slot 30, and the first slider 31 compresses the spring 32 until the active contact 33 contacts the passive contact 34. At this time, the display terminal shows that the composite support plate 12 is not broken.

[0028] Then, the driving power supply is started, and the driving power supply drives the first rotating shaft 16 to rotate, and the first rotating shaft 16 drives the first rotating disk 20 to rotate. Since the first rotating disk 20 is engaged with the second rotating disk 21 and the third rotating disk 22, the first rotating disk 20 drives the second rotating disk 21 and the third rotating disk 22 to rotate, and the inner walls of the test slots 25 on the second rotating disk 21 and the third rotating disk 22 exert pressure on both sides of the composite support plate 12.

[0029] Finally, when the composite support plate 12 breaks, the first baffle 26 and the second baffle 27 block the broken part of the composite support plate to prevent splashing. At this time, the composite support plate 12 is separated from the first slider 31, and the elastic potential energy of the spring 32 is released. The spring 32 pushes the first slider 31 to slide away from the passive contact 34, and the active contact 33 is separated from the passive contact 34. The display end shows that the composite support plate 12 is broken.

[0030] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
