Two end parts of the support structure are respectively connected with the left lower side beam and the right lower side beam; the middle beam penetrates through the support structure and is connected with the support structure; the top of riser with the both sides of diaphragm all are equipped with the first mounting hole that can fix corresponding funnel board. According to one embodiment of the invention, a supporting rib is arranged at an included angle formed by the vertical plate and the transverse plate; and the top of the support rib is provided with a second mounting hole capable of fixing a corresponding funnel plate. The supporting ribs play a reinforcing role and enable the funnel plate to be stressed uniformly.

In some embodiments of the invention, the ends of the brace structure are connected to the obtuse opposing side panels of the aluminum profile. This further enhances the load-bearing properties and strength. Preferably, the centre sill passes through and is welded to a support structure, the end of which is riveted to the edge plate opposite the obtuse angle of the aluminium profile. The funnel plate is fixed on the support structure through the first mounting hole, and the installation is simple and firm.

According to one embodiment of the present invention, the left and right lower side members are aluminum profiles, and the center sill is a steel material. Therefore, the self weight of the chassis assembly can be reduced, and the strength requirement can be further met.
