[0002] An electric vehicle (EV) is a vehicle powered by an electric motor or electric drive system. Unlike traditional internal combustion engine vehicles, EVs store energy in battery packs or other types of cells, then use an electric motor to convert this stored energy into mechanical power to propel the vehicle. EV charging systems, however, contain complex electronic control units and communication equipment, which are susceptible to external electromagnetic interference (EMI). Electromagnetic compatibility (EMC) testing can be used to evaluate and verify the charging system's performance under various electromagnetic interference conditions, ensuring that it does not malfunction or malfunction due to external interference.

The motor 205a is fixed to one side of the connecting column 202, and the output end is installed and connected to the threaded rod 205b. The threaded sleeve 205c is sleeved on the surface of the threaded rod 205b, and the guide rod 205d is hinged to the front and rear sides of the threaded sleeve 205c.

[0049] The threaded rod 205b can be rotated by driving the motor 205a, and the threaded sleeve 205c will drive the guide rod 205d to move, and the auxiliary detection member 206 is used.

[0050] Example 3

[0051] Reference Figure 4 and Figure 5 , which is the third embodiment of the present utility model, and is based on the first two embodiments.

[0052] Specifically, the driving member 205 further includes an L-shaped plate 205e. The L-shaped plate 205e is sleeved on the surface of the threaded rod 205b through a bearing, and one side of the L-shaped plate 205e is fixedly connected to the connecting column 202.

[0053] The fixed connection between the L-shaped plate 205e and the connecting column 202 can improve the stability of the threaded rod 205b during rotation.

[0054] Specifically, the positioning member 204 includes a tension spring 204a, a pull block 204b and an insertion rod 204c. The tension spring 204a is fixed to one side of the fixed shell 201 and is fixedly connected to the pull block 204b on the side away from the fixed shell 201. The insertion rod 204c is fixed to one side of the pull block 204b, and its surface penetrates into the interior of the retaining ring 203.

[0055] When the amplitude of the threaded rod 205b needs to be adjusted, the pull block 204b can be pulled to stretch the tension spring 204a to move. At this time, the insertion rod 204c will be separated from the inside of the retaining ring 203 as the pull block 204b moves. At this time, the connecting column 202 can be rotated to adjust the angle of the threaded rod 205b, and then the pull block 204b is released to reset it through the tension spring 204a so that the insertion rod 204c can be inserted into the inside of the retaining ring 203 again for positioning.

[0056] Specifically, the detection part 206 includes a vertical antenna 206a, a fixing ring 206b, an antenna rod 206c and a connecting ring 206d.

The connecting ring 206d is fixed to the surface of the antenna rod 206c, and is hinged to the guide rod 205d on one side.

[0057] Testing can be performed using the vertical antenna 206a and the antenna rod 206c. This is a prior art and will not be described in detail in this solution. Those skilled in the art will be able to clearly understand the working principle.

[0058] When in use, first, when it is necessary to adjust the test height, push the pull rod 105e to drive the connecting plate 105d to move. When the connecting plate 105d moves, it will drive the card plate 105b to squeeze the spring 105c. At this time, the card plate 105b will break away from the surface of the tooth plate 105a, and then drag the moving seat 104 to drive the slider 105g to rise in the inner cavity of the slide groove 105f. After adjusting the required height, loosen the pull rod 105e and reset it through the spring 105c to make the card plate 105b stuck on the surface of the tooth plate 105a for positioning. If you need to adjust the angle of the vertical antenna 206a and the antenna rod 206c, you can pull the pull block. 204b stretches the tension spring 204a and moves. At this time, the insertion rod 204c will detach from the inside of the retaining ring 203 as the pull block 204b moves. At this time, the angle of the threaded rod 205b can be adjusted by rotating the connecting column 202. Then the pull block 204b is released and the tension spring 204a is reset to allow the insertion rod 204c to be inserted into the inside of the retaining ring 203 again for positioning. If the antenna rod 206c needs to be unfolded, the motor 205a can be driven to rotate the threaded rod 205b. At this time, the threaded rod 205b will cause the threaded sleeve 205c to rotate, and the threaded sleeve 205c will cause the guide rod 205d to cooperate with the fixing ring 206b to unfold the antenna rod 206c and rotate at the same time.

[0059] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
