Description

Technical Field

[0001] The utility model relates to the technical field of automobile bodies, in particular to an upper crossbeam structure of a water tank. Background Art

[0002] The upper crossbeam of the water tank is usually welded with the relevant fixed bracket to form the upper crossbeam assembly of the water tank to meet the installation requirements of the carrier. Therefore, the upper crossbeam of the water tank is required to have a certain rigidity and strength, and the upper crossbeam of the water tank itself also needs to have certain modal requirements. The existing upper crossbeam of the water tank often adopts a complex structure and bloated matching of parts to achieve its function and performance, resulting in many product parts, heavy weight of parts, complex installation process, high production cost, and difficult to control the manufacturing precision of parts. Or the upper crossbeam of the water tank does not meet the rigidity and strength requirements, resulting in unstable installation and deformation of the assembly parts, and the upper crossbeam of the water tank cracks at the lock mounting plate, affecting the performance of the front cabin. Therefore, it is necessary to invent a new upper crossbeam structure of the water tank. Utility Model Content
