Description

Technical Field

[0001] The utility model relates to the technical field of current testing, in particular to a current testing device for vehicle instrument panels. Background Art

[0002] With the rapid development of the automotive industry, the functions of vehicle instrument panels have become increasingly complex and diverse. As an important information interaction interface between the vehicle and the driver, the accuracy and reliability of the vehicle instrument panel are crucial for the safe operation of the vehicle. During the production and maintenance of vehicle instrument panels, current testing is a key inspection link. Accurately measuring the current of each component in the vehicle instrument panel can promptly detect potential faults and defects, ensuring the normal operation of the instrument panel. Publication No.: CN217085080U discloses a current testing device for vehicle instrument panel production, and its technical solution includes: a workbench, an ammeter, a wire, an L-shaped plate, and a fixing seat. A support seat is welded to the lower surface of the workbench, and an L-shaped plate is installed on the upper surface of the workbench by bolts. An ammeter is installed on the upper surface of the L-shaped plate by bolts. A connector is threadedly installed at the bottom end of the ammeter. One end of the wire is fixed to the connector, and a pen rod is installed at the end of the wire away from the connector. A probe is installed at the end of the pen rod away from the wire. The fixing seat is slidably installed at the top end of the inner wall of the L-shaped plate, a spring is installed on the lower surface of the fixing seat, and a fixing buckle is welded to the end of the spring away from the fixing seat. The fixing buckle is clamped at the middle position of the wire. The utility model facilitates the measurement of the instrument panel while improving the measurement efficiency of the workpiece and meeting the usage requirements of personnel. However, for the above device, during the use of the device, there is no fixing component. When testing the vehicle instrument panel, if the vehicle instrument panel cannot be firmly fixed during the testing process, it may cause poor contact between the probe and the test point due to slight movement or shaking, thereby affecting the accuracy and stability of current measurement. At the same time, the operator needs to constantly pay attention to preventing the instrument from moving, unable to focus on the test operation and data reading, increasing the work difficulty and the possibility of errors, and thus needs to be improved.
