Description

Technical Field

[0001] The utility model relates to the technical field of electrostatic discharge simulation test, in particular to an electrostatic discharge simulation test device for smart cars. Background Art

[0002] The generation of static electricity is due to the fact that the atomic nucleus does not have enough attraction to the outer electrons, so that electrons are lost under the action of friction or other factors, thus causing the friction object to be negatively charged (i.e., the electrons gained are negatively charged, and the electrons lost are positively charged). In the case where the insulation performance of the friction object is relatively good, these charges cannot be lost and will accumulate. In addition, due to the extremely poor capacitance of the insulating material, although the charge amount is not large, the voltage is very high. At the moment of contacting the car door, discharge will occur between the human body and the vehicle, causing the fingers to be electrocuted. In order to alleviate the discharge phenomenon between the human body and the vehicle, it is necessary to simulate the electrostatic discharge of the vehicle through an electrostatic discharge simulation test device. After patent search, it was found that the publication number: CN209911472U discloses an electrostatic discharge simulator. The outlet direction of the discharge head is adjusted by rotating the button, so that the detection range of the electrostatic discharge simulator is larger and is not restricted by the test environment. A display screen is set at the rear end of the discharge part to make it more convenient and safer for users to observe.

[0003] Publication No.: CN209911472U. During the use of the disclosed electrostatic discharge simulator, the user needs to hold the discharge gun for a long time during the electrostatic discharge detection process, and the discharge gun cannot be fixed during the electrostatic discharge detection process, resulting in high labor intensity during the electrostatic discharge detection of smart cars. In order to solve the above problems, this application proposes a simulation test device for electrostatic discharge of smart cars. Utility Model Content
