Referring to fig. 1 to 3, an embodiment of a floor beam assembly according to the present invention will now be described. The floor beam assembly is fixedly arranged on a floor of an automobile body and comprises a main longitudinal beam 100, a floor front end connecting cross beam 200, a floor rear end connecting cross beam 300, a floor edge beam 400, a front end edge beam connecting cross beam 500 and a rear end edge beam connecting cross beam 600.
The main longitudinal beams 100 are arranged side by side, and the two main longitudinal beams 100 are used for extending in the front-rear direction of the vehicle body and are respectively located on the left side and the right side of the vehicle body. The main longitudinal beams 100 penetrate through a space region between the front impact beam 1500 and the rear impact beam in the front-rear direction (i.e., the longitudinal direction) of the vehicle body, the front ends of the two main longitudinal beams 100 are connected to the front impact beam 1500, and the rear ends of the two main longitudinal beams 100 are connected to the rear impact beam. The main longitudinal beam 100 is almost a long straight beam extending along the longitudinal direction of the vehicle body, and has few bending or arc transition structures, so that the main longitudinal beam 100 is firmer and can better transmit longitudinal stress.

the floor boundary beam and the main longitudinal beam on the same side are connected with the cross beam through the front end of the floor and connected with the cross beam through the rear end of the floor, the floor boundary beam and the main longitudinal beam on the other side form a left-right force transfer structure along the left-right direction of the vehicle body, and the front section of the longitudinal beam is connected with the rear section of the longitudinal beam through the middle section of the longitudinal beam and the floor boundary beam to form a front-back force transfer structure along the front-back direction of the vehicle body.
2. The floor beam assembly of claim 1 wherein one end of said floor front edge beam extends past said main longitudinal beam on the same side to and is connected to said floor front connecting cross beam.
3. The floor beam assembly of claim 1 or 2, further comprising a trunk connecting cross member for connecting the rear sections of the two side beams.
4. The floor beam assembly of claim 1 or 2, further comprising a cockpit front row connecting cross member for connecting the middle sections of said side beams.
5. The floor beam assembly of claim 4 wherein said cockpit front row connecting cross beam has at least two, said floor beam assembly further comprising a first short longitudinal beam for connecting two adjacent cockpit front row connecting cross beams.
6. The floor beam assembly of claim 5 further comprising a rear row of cockpit connecting cross members connecting the medial sections of said side beams.
7. The floor beam assembly of claim 6 wherein said rear deck connecting cross member has at least two, said floor beam assembly further comprising a second short longitudinal beam for connecting two adjacent rear deck connecting cross members.
8. The floor beam assembly of claim 6 further comprising two sets of cross members for connecting said side rail mid-section and said floor edge rail on the same side.
9. The floor beam assembly of claim 8 wherein said beam assembly includes a first cockpit front row of side beam connecting beams for corresponding to a body B-pillar, wherein one of said cockpit front row of side beam connecting beams is disposed corresponding to said first cockpit front row of side beam connecting beams, and wherein said first cockpit front row of side beam connecting beams and corresponding said cockpit front row of side beam connecting beams on both sides are adapted to construct a closed loop force structure with the body B-pillar.
10. An automobile, comprising the floor beam assembly of claims 1-9.
