The present embodiment relates to a vehicle, in which a vehicle rear floor structure according to the first embodiment is provided in a vehicle body of the vehicle. In addition, as shown in fig. 2 and 3, a rear floor side member rear section 105 is connected to the rear end of each rear floor side member 101, and a rear impact beam is connected between both side rear floor side member rear sections 105. The rear floor longitudinal beam rear section 105 is preferably made of extruded aluminum profile, so that the advantage of good crumpling and energy absorbing capacity of the extruded aluminum profile is utilized.
As shown in fig. 9 and 10, the rear impact beam of the present embodiment includes an impact beam body 3 having a hollow inside, the impact beam body 3 having two vertical plate bodies arranged oppositely, and a plurality of cross plate bodies 303 connected between the two vertical plate bodies. The middle parts of at least two adjacent transverse plate bodies 303 arch to one side in the width direction, the width direction of the transverse plate bodies 303 is the front-back direction of the automobile, and the arch-out directions of the two adjacent transverse plate bodies 303 with the middle parts arched to one side are opposite.
Specifically, two riser bodies are arranged along the front-back direction of the automobile, and therefore for convenience of description, the two riser bodies are respectively referred to as a front riser body 301 and a rear riser body 302 in the embodiment, the front riser body 301 faces the automobile head side, and the rear riser body 302 faces the automobile rear side. A space for arranging each transverse plate body 303 is formed between the front vertical plate body 301 and the rear vertical plate body 302, each transverse plate body 303 is horizontally arranged and vertically arranged at intervals, and the front side and the rear side of each transverse plate body 303 are respectively connected with the vertical plate body on the corresponding side.
In this embodiment, as shown in fig. 10, as a preferred exemplary structure, each of the transverse plate bodies 303 is arched from the middle portion to one side in the width direction, and meanwhile, the number of the transverse plate bodies is specifically four, and the plurality of transverse plate bodies 303 are also divided into two pairs which are distributed at intervals up and down. That is, with the orientation shown in fig. 10 as a reference, one pair is formed by the two horizontal plate members 303 positioned above, and the other pair is formed by the two horizontal plate members 303 positioned below.
Based on the arrangement of the horizontal plates 303 in two pairs, in each pair of horizontal plates 303 of the present embodiment, the arching directions of the two horizontal plates 303 are also arranged oppositely. Also, it should be noted that, as a preferred embodiment, a cross plate 303 is connected between the top of each of the two vertical plates and between the bottom of each of the two vertical plates. From this the vertical plate body of both sides forms the outline of crashproof roof beam body 3 with the horizontal plate body 303 of top and bottom jointly to the cross section of whole crashproof roof beam body 3 also is the mesh style of calligraphy, with better outward appearance effect.
The two pairs of transverse plate bodies 303 are designed, so that the structure of the anti-collision beam body 3 can be simplified on the basis of meeting the use requirement, and the manufacturing cost of the anti-collision beam body 3 is reduced.

Still referring to fig. 10, in the present embodiment, the arching positions of the cross plates 303 are aligned along the height direction of the impact beam body 3, so that the design can contribute to the improvement of the collapse performance of the impact beam. In addition, as a whole, the middle part of the length direction of the impact beam body 3 of the embodiment also arches to one side, and thus the impact beam body 3 is arc-shaped. At this moment, the length direction of the anti-collision beam body 3 is specifically the left and right directions of the automobile, and the anti-collision beam body 3 is integrally designed into an arc structure, so that compared with a straight structure, the rigidity of the anti-collision beam body 3 can be improved, and the crumple energy absorption capacity of the anti-collision beam body in collision is improved.
In addition, as shown in fig. 9, a connecting seat 4 is also connected to one side of the impact beam body 3, and one connecting seat 4 is provided near each of both ends of the impact beam body 3. Meanwhile, as an exemplary structure, as shown in fig. 3, the connection socket 4 also includes a connection box having a cavity formed therein, and a connection plate connected to the connection box. Wherein, the connecting box links to each other with anticollision roof beam body 3, then is provided with the connecting hole on the connecting plate.
It should be noted that, in the specific implementation, the impact beam body 3 of the present embodiment preferably uses an extruded aluminum profile. Through adopting the extrusion aluminium alloy, not only can guarantee the structural strength of anticollision roof beam body 3 to utilize the extrusion aluminium alloy advantage that the energy-absorbing capacity that contracts of bursting, also can promote the performance of anticollision roof beam body 3 in the collision.
The vehicle of the embodiment adopts the vehicle rear floor structure of the first embodiment, so that the connection strength between the rear floor body 11 and the threshold beam can be improved, and the torsional rigidity and the force transmission effect of the whole vehicle can be improved. In addition, by adopting the rear anti-collision beam, when collision occurs, the designed transverse plate body 303 can be arched, so that deformation and collapse of the anti-collision beam body 3 are facilitated, collision energy is absorbed, the collapse energy absorption performance of the anti-collision beam can be improved, and the improvement of the collision safety of an automobile is facilitated.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
