Description
Technical Field
[0001] The utility model relates to the technical field of automobiles, in particular to a front floor assembly, an automobile floor assembly and an automobile. Background Art
[0002] As one of the main parts of the car body, the front floor of the car is the foundation of the car body. Because of its large manufacturing area and the connection with other parts such as seats and battery packs through the body crossbeams and longitudinal beams, it is easy to produce large deformation under the action of external forces, which has a great impact on the stiffness and strength of the entire car body. The main source of force on the floor during the production process is the workers stepping on it when installing other parts of the car body. If the floor strength is weak, it may cause irreversible permanent deformation of the floor; when the rear passengers step hard with their feet during the use of the vehicle, the floor may produce abnormal noises with the battery pack below, affecting the driving experience. However, due to the influence of materials, material thickness and the span of the body crossbeams, its structural strength is often relatively weak. If it is greatly deformed after being subjected to force, it will not only affect the appearance of the car body, but also have a great impact on the installation of other parts, and even affect the performance of the entire car body.
[0003] The prior art proposes a front floor structure of an automobile, comprising a front floor panel and a front crossbeam, a rear crossbeam and a front longitudinal beam of a seat arranged on the front floor panel, wherein a first reinforcing rib is formed at a position on the front floor panel covered by the front longitudinal beam, the first reinforcing rib protrudes in a direction away from the front longitudinal beam, and the interior of the first reinforcing rib is longitudinally penetrated, and a cavity is formed between the first reinforcing rib and the front longitudinal beam. The front floor structure of the prior art adopts the form of adding reinforcing ribs, which can meet the structural strength of the floor in most cases, but some structural reinforcing ribs often have limited effects and cannot meet the structural strength requirements. Utility Model Content
[0004] One of the purposes of the utility model is to provide a front floor assembly to solve the problem that the existing front floor has low strength and workers step on it when installing other parts of the vehicle body, which causes the floor to have irreversible permanent deformation.
[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:
[0006] A front floor assembly comprises a front floor body, on which a reinforcing plate is arranged, the reinforcing plate is attached to and fixed on the top of the front floor body, and reinforcing ribs are arranged on the reinforcing plate.
[0007] Furthermore, the number of the reinforcing ribs is multiple and they are distributed horizontally and vertically on the reinforcing plate.
[0008] Furthermore, two ends of the reinforcement plate are respectively fixedly connected to the front cross beam of the rear floor and the rear cross beam for installing the front seats.
[0009] Furthermore, after the front seats are installed, the rear cross beam is fixedly connected above the front floor body and forms a cavity structure between the front floor body.
[0010] Furthermore, the side portion of the front floor body is fixedly connected to the door sill side beam.
[0011] Furthermore, the two ends of the rear cross beam after the front seats are installed are respectively fixedly connected to the door sill side beams on both sides.
[0012] Furthermore, a front seat connecting longitudinal beam is provided on the front floor body, a cavity structure is formed between the front seat connecting longitudinal beam and the front floor body, and two ends of the front seat connecting longitudinal beam are respectively fixedly connected to the front seat mounting rear beam and the front seat mounting front beam.
[0013] Furthermore, the front row seat mounting front cross beam is fixedly mounted on the front floor body, is spaced apart from the front row seat rear cross beam, and forms a cavity structure with the front floor body.
[0014] An automobile floor assembly comprises the above-mentioned front floor assembly.
[0015] A car comprises the above-mentioned car floor assembly.
[0016] Beneficial effects of the utility model:
[0017] The utility model adds a reinforcing plate to the front floor body without increasing the thickness of the front floor material, changing the material, or changing the vehicle body structure, thereby increasing the strength of the front floor and reducing the risk of being stepped on. At the same time, by adding the reinforcing plate to meet the residual deformation of the structure after being stressed, the rigidity and strength of the front floor are increased.
[0018] The utility model improves the anti-deformation capability of the structure, does not require a complicated forming mold, has a high degree of commonality, and can meet the front floor structure performance requirements of different vehicle models. BRIEF DESCRIPTION OF THE DRAWINGS
