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.

The present application relates to the technical field of paint, in particular to an alkali-resistant waterproof exterior wall paint and a preparation method thereof. In order to further improve the water resistance and alkali resistance of the stone-like paint, the stone-like paint is improved, a texture protective paint is added to the structure of the traditional stone-like paint, and colored sand is added to the components, so that a concave-convex texture can be provided for the surface of the stone-like paint after the stone-like paint is finally formed. In addition, boron nitride nanosheets are added to the texture protective paint and modified, and fluorine and silicon elements are introduced into the boron nitride nanosheets, so as to improve the chemical corrosion resistance of the resin, prevent the infiltration and invasion of external corrosive media, and effectively improve the acid and alkali resistance of the resin paint.

The utility model discloses a front subframe and car, including front crossbeam, rear crossbeam, left longitudinal beam and right longitudinal beam, left longitudinal beam and right longitudinal beam are symmetrically set up, left longitudinal beam and right longitudinal beam all include longitudinal beam upper plate and longitudinal beam lower plate, longitudinal beam upper plate and longitudinal beam lower plate extend along the longitudinal direction, at least one edge of longitudinal beam upper plate and longitudinal beam lower plate is equipped with the flanging, longitudinal beam upper plate and longitudinal beam lower plate are welded and form the box -like structure with the inner chamber through the flanging, the middle position of longitudinal beam upper plate is formed recessed area through setting corner fold line. The utility model can realize the specific deformation mode of subframe, to protect the passenger safety, through setting corner fold line formation recessed area, realize sufficient collision energy absorption, realize the established collision motor movement track, reduce the invasion amount to the driver's cabin, greatly strengthen the crash performance, protect the battery package when colliding not to be touched, greatly improve the collision electric safety requirement.
