Description

Technical Field

[0001] This utility model relates to the field of automobile manufacturing technology, and in particular to an automobile front floor assembly. Background Technology

[0002] Against the backdrop of a global effort to promote the development of low-energy, low-emission transportation, reducing vehicle weight has become a crucial measure for energy conservation and emission reduction. Because vehicle drag is positively correlated with weight, reducing vehicle weight effectively lowers energy consumption and emissions, whether for traditional gasoline-powered vehicles or new energy vehicles. Aluminum alloys possess advantages such as high specific strength, good plasticity, ease of processing and forming, corrosion resistance, and recyclability, making them widely used in the manufacture of automotive front floor assemblies to achieve lightweighting goals.

[0003] During vehicle operation, vibrations caused by uneven road surfaces generate alternating stress. Asymmetrical structures cannot effectively disperse vibration energy, which can easily lead to stress concentration points in the area where the seat crossbeam connects to the floor. This may cause metal fatigue cracks and even lead to the risk of deformation of the vehicle body side panels. Utility Model Content

[0004] The purpose of this utility model is to provide a front floor assembly for automobiles, which is symmetrically fixed to the front and rear sides of the seat crossbeam through a first reinforcing channel and a second reinforcing channel to form a "front and rear clamping" reinforcement structure, effectively resisting vertical loads and alternating stresses. The connecting channel runs horizontally through the first reinforcing channel and the second reinforcing channel to form a "U"-shaped rigid frame, which improves the collision energy absorption rate and reduces the risk of deformation of the vehicle body side.

[0005] To achieve the above objectives, a front floor assembly for automobiles is provided, comprising: a floor plate, on which two seat crossbeams are fixedly connected to the left and right sides of the upper surface of the floor plate; a first reinforcing channel and a second reinforcing channel are fixedly connected to the front and rear sides of the outer surfaces of the two seat crossbeams; two connecting channels are fixedly connected between the first and second reinforcing channels; the upper surfaces of the two connecting channels are provided with connecting channel mounting grooves; and the upper surfaces of the first reinforcing channel are provided with two reinforcing channel mounting grooves, which are symmetrically arranged on the front and rear sides of the first reinforcing channel. Through the multiple reinforcing structures and mounting groove design, the strength of the seat area is improved and the component integration efficiency is optimized.

[0006] According to the aforementioned automotive front floor assembly, the internal layout of the second reinforcing channel is identical to that of the first reinforcing channel, and both connecting channels are symmetrically arranged on the front and rear sides of the seat crossbeam. This symmetrical layout ensures consistent left-right mechanical properties and enhances overall structural stability and load-bearing balance.

[0007] According to the aforementioned automotive front floor assembly, a central channel is fixedly connected between both seat crossbeams, and the central channel is located in the middle of the upper surface of the floor plate. The central channel strengthens the central support of the floor plate, improves torsional stiffness, and optimizes the longitudinal load transfer path of the vehicle body.

[0008] According to the aforementioned automotive front floor assembly, side channels are fixedly connected to both the left and right sides of the upper surface of the floor plate, and the side channels are located on the side walls of the seat crossbeams. Three seat mounting slots are formed on the upper surfaces of both seat crossbeams. The side channels cooperate with the seat mounting slots to enhance lateral impact resistance and ensure the stability of the seat installation.

[0009] According to the aforementioned automotive front floor assembly, the upper surface of the side passage is provided with a plurality of mounting and positioning grooves, which are evenly distributed on the upper surface of the side passage. The evenly distributed mounting and positioning grooves facilitate precise installation of accessories and distribute stress, improving assembly convenience.

[0010] According to the aforementioned automotive front floor assembly, the sidewalls of the side passages are fixedly connected to the front and rear ends of a first reinforcing passage and a second reinforcing passage, respectively. Both the first and second reinforcing passages have arc-shaped cross-sections. The closed-loop connection and arc-shaped cross-sections optimize structural strength and aerodynamic performance, reducing the risk of stress concentration.

[0011] The above-mentioned solution has the following beneficial effects:

[0012] This utility model is provided with a first reinforcing channel, a second reinforcing channel, a connecting channel, a reinforcing channel mounting groove, and a connecting channel mounting groove. The first and second reinforcing channels are symmetrically fixed to the front and rear sides of the seat crossbeam to form a "front and rear clamping" reinforcement structure, which effectively resists vertical loads and alternating stresses. The connecting channel runs horizontally through the first and second reinforcing channels to form a "U"-shaped rigid frame, which improves the collision energy absorption rate and reduces the risk of vehicle body side deformation.

[0021] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0022] Reference Figures 1-4 This utility model discloses a front floor assembly for automobiles, comprising: a base plate 1, with two seat crossbeams 5 fixedly connected to the left and right sides of the upper surface of the base plate 1. The seat crossbeams 5, fixedly connected to the base plate 1, provide a supporting foundation for seat installation and distribute the force of the seat to the base plate 1. A first reinforcing channel 7 and a second reinforcing channel 8 are fixedly connected to the front and rear sides of the outer surfaces of the two seat crossbeams 5. The first reinforcing channels 7 and the second reinforcing channels 8 are symmetrically arranged on the outer surfaces of the seat crossbeams 5 to enhance the structural strength of the seat crossbeams 5 and improve their resistance to deformation. Two connecting channels 9 are fixedly connected between the first reinforcing channels 7 and the second reinforcing channels 8. Connecting channel 9 connects the first reinforcing channel 7 and the second reinforcing channel 8 to form a transverse support structure, strengthening the rigid connection between them. The upper surface of both connecting channels 9 is provided with connecting channel mounting grooves 11, which provide installation and positioning interfaces for external components (such as pipes and wire harnesses) to facilitate component integration and assembly. The upper surface of the first reinforcing channel 7 is provided with two reinforcing channel mounting grooves 10, which are symmetrically arranged on the front and rear sides of the first reinforcing channel 7. The reinforcing channel mounting grooves 10 are used to install reinforcing parts or accessories. The symmetrical layout ensures that the first reinforcing channel 7 is subjected to uniform force and improves the local structural stability.

[0023] The internal structure of the second reinforcing channel 8 is the same as that of the first reinforcing channel 7. The second reinforcing channel 8 and the first reinforcing channel 7 are structurally symmetrical and together form a reinforcing system on the front and rear sides of the seat crossbeam 5, ensuring consistent mechanical performance on both sides. The two connecting channels 9 are symmetrically arranged on the front and rear sides of the seat crossbeam 5. The connecting channels 9 are symmetrically arranged on the front and rear sides of the seat crossbeam 5 to evenly transfer the load between the seat crossbeam 5 and the first reinforcing channel 7 and the second reinforcing channel 8, improving the overall structural symmetry. A central channel 2 is fixedly connected between the two seat crossbeams 5, and the central channel 2 is located in the middle of the upper surface of the base plate 1. The central channel 2 connects the left and right seat crossbeams 5 to form a central support frame, enhancing the torsional rigidity of the middle of the base plate 1, and providing a path for the longitudinal load transfer of the vehicle body. Side channels 3 are fixedly connected to the left and right sides of the upper surface of the base plate 1, and the side channels 3 are located on the side walls of the seat crossbeam 5. The side channels 3 are located on the outside of the seat crossbeam 5 and together with the seat crossbeam 5 and the base plate 1, they form an edge support structure, improving the side rigidity of the vehicle body. To enhance impact resistance, three seat mounting slots 6 are provided on the upper surface of each of the two seat crossbeams 5. These slots provide installation positions for the seat fixing bolts, and their layout ensures the stability and reliability of seat installation. Several mounting positioning slots 4 are provided on the upper surface of the side channel 3, and these slots are evenly distributed. These slots are used to position and install side accessories (such as interior panels and protective panels). Their even distribution facilitates precise control of accessory installation and stress distribution. The side walls of the side channel 3 are fixedly connected to the front and rear ends of the first reinforcing channel 7 and the second reinforcing channel 8, respectively. The side channel 3, through its connection with the first reinforcing channel 7 and the second reinforcing channel 8, forms a closed-loop support structure, enhancing the connection strength between the side of the vehicle body and the seat area. The cross-sections of the first reinforcing channel 7 and the second reinforcing channel 8 are both arc-shaped. This arc-shaped cross-section design makes the stress distribution of the first reinforcing channel 7 and the second reinforcing channel 8 more uniform under stress, improving fatigue resistance and optimizing aerodynamic characteristics.

[0024] Working Principle: First, the base plate 1 is fixed to the vehicle assembly station as a basic frame, ensuring its levelness is aligned with the vehicle body reference. The base plate 1, as the core load-bearing component, provides an installation reference for other components through its upper surface mounting structure. Two seat crossbeams 5 are symmetrically installed on the left and right sides of the upper surface of the base plate 1, and fixed to the base plate 1 by bolts or welding. The seat crossbeams 5 serve as direct supports for seat installation, and their positions must strictly correspond to the vehicle seat layout to ensure that the force after seat installation is evenly transmitted to the base plate 1. First reinforcing channels 7 and second reinforcing channels 8 are installed on the front and rear sides of the outer surface of the seat crossbeams 5, respectively, and fixed to the seat crossbeams 5 by welding or fasteners, thus reinforcing the strength of the seat crossbeams 5. Subsequently, two connecting channels 9 are installed between the first reinforcing channel 7 and the second reinforcing channel 8. The two ends of the connecting channels 9 are fixed to the first reinforcing channel 7 and the second reinforcing channel 8, respectively, forming a lateral support structure to enhance the rigid connection between them. Simultaneously, the connecting channel mounting grooves 11 provide space for the installation of drainage pipes or wiring harnesses. A central channel 2 is installed between the two sides and fixed to the middle of the upper surface of the base plate 1. The central channel 2 serves as a longitudinal support frame, which not only enhances the torsional rigidity of the middle of the base plate 1, but also provides a path for load transfer between the front and rear ends of the vehicle body. At the same time, side channels 3 are installed on the left and right sides of the base plate 1, and their side walls are fixed to the outside of the seat crossbeam 5. The front and rear ends of the side channels 3 are welded or bolted to the ends of the first reinforcing channel 7 and the second reinforcing channel 8, respectively, forming a closed-loop support structure composed of the side channels 3, the seat crossbeam 5, and the reinforcing channels, which improves the impact resistance of the vehicle body side. The seat base is fixed with bolts in the three seat mounting slots 6 on the upper surface of the seat crossbeam 5 to ensure the stability of the seat installation. The side accessories of the vehicle body (such as interior panels, guard plates, etc.) are installed in the mounting positioning slots 4 on the upper surface of the side channels 3. The even distribution of the positioning slots can ensure the installation accuracy and force balance of the accessories. At the same time, in the reinforcing channel mounting slots 10 of the first reinforcing channel 7, reinforcement parts or sensor brackets and other accessories are installed according to design requirements. The symmetrical layout of the mounting slots ensures the force balance of the first reinforcing channel 7.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
