[0001] This utility model relates to the field of vehicle display installation technology, and more specifically, to a special-shaped nut equipped with a spring washer. Background Technology

[0002] In the automotive manufacturing industry, the installation quality of in-vehicle displays plays a crucial role in user experience and driving safety. Currently, the installation methods for in-vehicle displays have certain limitations. During installation, the traditional nut connection method cannot flexibly adjust the installation position of the display. After the in-vehicle display is connected to the bracket and installed on the fixed structure with bolts, if the position of the display deviates and does not meet the design requirements, it is often necessary to disassemble and adjust the entire installation structure again. This operation is cumbersome, time-consuming, and labor-intensive, which not only increases production time and costs but may also damage parts due to repeated disassembly, affecting product quality. Therefore, we propose a special-shaped nut equipped with a spring washer to solve the above problems. Utility Model Content
