Usually, the electromagnetic brake is also used in cooperation with a mechanical brake system (such as a brake, a brake, a drum brake or a disc brake) to ensure that sufficient braking force can be provided under various road conditions and vehicle speeds.

[0003] In order to ensure the safety of the electric riding car, relevant tests need to be carried out. For high-quality electric riding cars, the requirements for testing are becoming increasingly stringent. The test process is roughly as follows: after the vehicle is subjected to 3-minute waterproof test, the voltage output device is connected, the output voltage of the voltage output device is set to 2500V, one end of the voltage output device is connected to the vehicle charging port, the other end is connected to the brake handle, and the operation is continued for 1 minute. Then operate the brake handle (at this time the vehicle is still connected to the voltage output device), and check whether the electromagnetic brake system can work normally.

[0004] During the aforementioned test, there are often cases that do not pass. After analysis and research, the applicant found that the main reasons are: 1. The insulation of the brake handle adopts a spraying process, and the part for installing the induction box is located at the inside corner of the bracket, which is prone to not being sprayed in place, resulting in no spraying in place; 2. The conditions during the test are relatively harsh, which causes the lead insulation layer to break. The above-mentioned situations result in that after the waterproof test, the residual water droplets connect the core wire and the metal wall of the bracket, causing the voltage resistance test to fail.
