[0042] In related technologies, the trailer crossbeam assembly, as an important component of the towing system, is mainly used to connect the towing vehicle and the unpowered trailer to achieve stable towing. Existing trailer crossbeam assemblies are relatively simple in function, mainly limited to towing applications, resulting in high costs.

[0043] In this embodiment of the utility model, multiple brackets 30 are added to the second connecting surface 22. The brackets 30 are used to fix the bumper 200, which increases the function of the trailer crossbeam assembly 100. The trailer crossbeam assembly 100 can act as a frame to support the bumper 200 and can also realize the installation of the bumper 200. In addition, multiple brackets 30 increase multiple stress-bearing parts, which can stably support the bumper 200 while reducing costs.
