Description

TECHNICAL FIELD

[0001] The application relates to the technical field of automobile parts, in particular to a light-weight wing panel support based on high-pressure die casting. BACKGROUND

[0002] At present, the left rear wing panel support used by commercial vehicles is a steel plate stamping and welding support or a steel pipe bending and welding support. The left rear wing panel support is a typical wall-hanging structure. When the vehicle runs on uneven roads, the vehicle will be twisted and deformed. Even when the vehicle runs on flat roads, the vehicle may vibrate due to excitation from the road and the engine. This brings great challenges to the light-weight design of the wing panel support. In order to improve the strength, multiple sheet metal reinforcing plates need to be welded inside, resulting in a large number of parts and a large amount of welding work, which leads to high cost and heavy weight, and is not conducive to the light-weight design of the vehicle body. Therefore, further improvement is needed. CONTENT OF THE UTILITY MODEL
