Middle row seat mounting cross beam

Abstract

The invention discloses a middle row seat mounting cross beam, and relates to the technical field of automobile manufacturing. The middle row seat mounting cross beam comprises a seat cross beam located between a rear floor front cross beam and a rear floor lower cross beam. The two ends of the seat cross beam respectively penetrate through rear longitudinal beams to be fixedly connected with threshold beams. A plurality of seat mounting supports are arranged on the seat cross beam. Compared with the prior art, according to the middle row seat mounting cross beam, a seat in the middle and seats on two sides are mounted on the seat mounting supports, middle-row seats can be mounted through just two parts, few types of tools for production are required correspondingly, and the production cost is low. The seat mounting supports are arranged on the seat cross beam, a cantilever structure is eliminated, and the rigidity of a seat mounting point is improved. When a vehicle body is subjectedto side collision, through the rear floor front cross beam, the rear floor lower cross beam and the seat cross beam for force transmission, a side collision force transmission path is increased, sideimpact bearing performance is improved, and meanwhile, the torsional rigidity is effectively improved.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to a crossbeam for installing middle-row seats. Background technique [0002] The installation structure of the middle seat in the traditional car is as follows: figure 1 As shown, two seat longitudinal beams 12 are welded between the rear floor front beam 13 and the rear floor lower beam 16, and the outer sides of the two seat longitudinal beams 12 respectively have side seat brackets 15 protruding outwards. The middle seat brackets 11 are respectively welded on the first seat longitudinal beam 12, and the side seat mounts 14 are respectively welded on the two rear longitudinal beams 17, and the seat in the middle is installed on the two middle seat brackets 11, The seats located on both sides are mounted on the side seat frame 15 and the side seat mount 14 . There are many types of parts used in the installation of the middle row of seats, and correspondingly ma...
