Description
Technical Field
The invention relates to the technical field of vehicles, in particular to a vehicle floor and a vehicle.
Background
With the development of vehicles, people have higher and higher requirements on the comfort of the vehicles. The static rigidity of the vehicle body mounting point reflects the deformation resistance of the vehicle body mounting point, and the low static rigidity of the vehicle body mounting point easily causes problems of abnormal sound, shaking of mounting parts and the like, and influences the NVH (Noise, Vibration and Harshness) performance and riding comfort of the vehicle.
Influenced by the arrangement mode of the seat, the rigidity value of the installation point of the seat is often lower, and the comfort of the vehicle is seriously influenced. At present, in order to improve the rigidity of a seat mounting point, a reinforcing plate is often added on a rear floor to improve the rigidity value of a seat mounting area. However, in the current vehicle design, the vehicle body performance is improved on the premise that the vehicle mass is as small as possible, and the adoption of the mode of increasing the reinforcing plate usually increases the weight of the vehicle more, but the improvement effect of the rigidity is poor, which is contrary to the large direction of the light weight of the current vehicle.

In view of the above, the present invention is directed to a vehicle floor and a vehicle that can improve the rigidity of a vehicle seat installation region without adding a large amount of weight to the vehicle.
In order to achieve the purpose, the technical scheme of the invention is realized as follows:
a vehicle floor includes a floor main body, and further includes a mounting bracket for mounting a seat, the mounting bracket including a bracket main body fixed to an underside of a seat mounting region of the floor main body, a position of the bracket main body for connecting a seat fixing member being formed with a recess opening toward the floor main body.
Further, the bottom position of the concave part is provided with an installation hole for installing the seat fixing piece.
Further, the structural shape of the part of the floor main body, where the bracket main body is arranged, is matched with the structural shape of the bracket main body.
Further, the vehicle floor further includes a transversely extending lower reinforcing cross member fixed to the lower side of the floor main body, and one end of the bracket main body is fixed between the lower reinforcing cross member and the floor main body.
Further, the concave portion extends from the outer side of the lower reinforcing cross beam to a position between the lower reinforcing cross beam and the floor main body, and a concave structure matched with the concave portion is formed on the lower reinforcing cross beam.
Furthermore, the lower reinforcing beam comprises a groove-shaped main body with a downward concave middle part and an upward opening, flanges are respectively formed on two sides of the opening of the groove-shaped main body, the bracket main body is fixedly connected with the flanges on one side, and the concave structure is formed on the flanges.
Furthermore, the bracket main body is attached to the wall of the groove-shaped main body from the connected flanging and extends to the middle concave part of the groove-shaped main body to form an extension part.
Furthermore, the bracket main body is welded and fixed with the connected flanging, and the extending part of the bracket main body is welded and fixed with the bottom of the middle concave part of the groove-shaped main body.
Furthermore, the vehicle floor further comprises an upper reinforcing cross beam fixed on one side above the floor main body, and the upper reinforcing cross beam corresponds to the lower reinforcing cross beam in position.
The present invention can enhance the bending resistance of the seat installation region of the vehicle floor by forming the recess portion at the position of the bracket main body for connecting the seat anchor, so that the rigidity of the seat installation region is enhanced, thereby improving the NVH performance and the riding comfort of the vehicle. Compared with the mode of improving the rigidity by adding the reinforcing plate in the prior art, the mode of improving the rigidity of the seat installation area has the advantages that the vehicle does not need to increase more weight, and the rigidity improvement effect is obvious.
The invention also provides a vehicle which is provided with the vehicle floor.
