[0039] like Figure 1-6 As shown, the vibration test platform for the frame of the two-wheeled electric vehicle includes:

[0040] A base 1, a support 11 is fixedly connected to the bottom side surface of the base 1, and a hanger 2 is attached to the top side surface of the base 1;

[0041] The limiting guide rail 3 is fixedly installed on the top side of the base 1;

[0042] A position adjustment mechanism 4 is installed on the top side of the base 1, and a fixing frame 7 is installed on the top side of the position adjustment mechanism 4;

[0043] Drive mechanism 5, which is installed on the top side of position adjustment mechanism 4, is used for chassis vibration testing drive;

[0044] The elastic circulation component 6 is installed on the top side of the fixed frame 7.

[0045] The suspended frame 2 is designed to lift the electric vehicle frame, facilitating subsequent fixation using clamps. The position adjustment mechanism 4 then adjusts the position of the side-viewing front vibration table. The position adjustment mechanism 4 moves along the limiting guide rail 3, adjusting the top elastic circulation component 6 to cooperate with the frame, facilitating the fixation of frames of different test sizes. After the position adjustment mechanism 4 is stably fixed, the drive mechanism 5 is activated. The drive mechanism 5 causes the elastic circulation component 6 to circulate along the top side of the fixed frame 7, facilitating the vibration of the top side of the frame for side-viewing. The operation is simple and meets the side-viewing requirements.

[0046] The position adjustment mechanism 4 includes a limiting seat 41, a threaded post 42, a rotating wheel 43, an adjusting seat 44, a moving seat 45, and a fastening bolt 46.

The moving seat 45 moves along the base 1, thereby facilitating the adjustment of the position of the front vibration table according to the size requirements of the frame. This makes it easier for the front vibration table to adapt to the frame of the corresponding size, improving the overall applicability of the front vibration table. After adjusting the position of the moving seat 45, the fastening bolt 46 is rotated, and the end of the fastening bolt 46 moves down and fits against the moving seat 45, so that the moving seat 45 is stably fixed on the surface of the base 1, ensuring the overall stability of the vibration damping table.

The second pulley 54 drives the roller 55 to rotate. The roller 55 drives the eccentric wheel 57 to rotate. Through the eccentric wheel 57, the elastic circulation component 6 is activated, enabling the elastic circulation component 6 to slide cyclically on the top side of the fixed frame 7.

[0053] The elastic circulation assembly 6 includes a sliding column 61, a clamping part 62, an elastic spring 63, a limiting plate 64, a rotating part 65, and an annular shell 66. The sliding column 61 passes through the top side of the fixed frame 7. The clamping part 62 is fixedly installed at the top of the sliding column 61.

[0057] The clamping part 62 enables the test installation at the front end of the frame. Under the action of the elastic spring 63, the frame can be vibrated repeatedly to meet the vibration requirements.
