The invention provides a fuel cell hydrogen energy automobile aluminum alloy instrument board cross beam. The fuel cell hydrogen energy automobile aluminum alloy instrument board cross beam comprisesa main pipe beam and a floor support; the main pipe beam is an aluminum alloy section with a polygonal cross section, the main pipe beam is provided with a plurality of first instrument board mountingbrackets arranged at intervals in the length direction of the main pipe beam, the bottom of each first instrument board mounting bracket is provided with a U-shaped matching groove, and the matchinggrooves are attached to the surface of the main pipe beam and are connected with the surface of the main pipe beam through welding; the floor support is in an H shape, the upper end of the floor support is connected with the main pipe beam in a welded mode, a plurality of second instrument board installation supports extending outwards are arranged on the two sides of the floor support respectively, and a plurality of air conditioner installation supports extending inwards are further arranged on the two sides of the floor support. The instrument board cross beam has the beneficial effects that the problem that a traditional instrument board cross beam is large in framework weight is solved, the weight is reduced by 30%-40%, and light weight of products is achieved; the investment of toolsand molds required by forming processing is low, and the production cost is saved.
