A commercial vehicle dashboard structure
This application relates to the field of commercial vehicle body technology, and particularly to a front bulkhead structure for a commercial vehicle. The front bulkhead structure includes a front bulkhead beam, which comprises an upper crossbeam and a lower crossbeam, connected by a front bulkhead longitudinal beam. The upper crossbeam includes an upper crossbeam body and an upper crossbeam armrest mounting location, with the thickness of the armrest mounting location greater than the thickness of the upper crossbeam body. The lower crossbeam includes a mounting bracket, one end of which connects to the front bulkhead longitudinal beam, with the thickness of the mounting bracket greater than the thickness of the upper crossbeam body. This application provides a front bulkhead structure for commercial vehicles to address the problem in related technologies where adding reinforcing plates to strengthen the front bulkhead increases the number of parts and welding processes, making it difficult to achieve lightweight design.
