Technical Field
The utility model relates to a technical field of automobile design and manufacturing, more specifically say, the utility model relates to a front floor front beam structure.
Background
In the prior art, as shown in fig. 1-2, the front floor front beam 1 is made of a stamped steel plate. The connecting structure is connected to the floor 2 at the middle position through spot welding, and is connected to the threshold side beam inner plate 3 through spot welding from left to right. The front cross beam of the front floor is generally formed by drawing, and a high-strength steel plate is generally adopted to ensure the side impact effect and the strength of a seat mounting point. A nut plate 4 is typically added at the seat mounting point to increase the strength of the mounting point. The front floor front beam can meet the side impact effect and the mounting point strength, but the part weight is heavier, and the cost of the die is higher due to the adoption of punch forming. To the present situation that the vehicle body needs to be lightened, a structure is needed to be designed to reduce the weight of the front floor front cross beam and meet the performance requirements of the vehicle body.
SUMMERY OF THE UTILITY MODEL
For solving the above-mentioned technical problem that exists among the prior art, the utility model aims to provide a front floor front beam structure.
The utility model discloses a front floor front beam structure, its characterized in that: the steel front floor comprises a steel front floor, steel side beam inner plates arranged on two sides of the front floor and an aluminum front cross beam; the left side and the right side of the aluminum front cross beam are provided with L-shaped connecting plates, the front side and the rear side of the aluminum front cross beam are provided with flanges, the flanges are connected with the front floor through a self-piercing riveting structure, and the steel edge beam inner plate is connected with the L-shaped connecting plates through a self-piercing riveting structure; and a seat mounting point is arranged on the aluminum front cross beam, and a steel threaded pipe is arranged at the seat mounting point.
Wherein, the cross-section of aluminium system front beam has the line of a word strengthening rib structure.
The L-shaped connecting plates are welded on the aluminum front cross beam, and the L-shaped connecting plates on the left side and the right side are symmetrically arranged.
Compared with the prior art, the utility model discloses a front floor front beam structure has following beneficial effect:
the utility model discloses a structure can show the weight that alleviates front floor front beam, and can satisfy the performance requirement of automobile body, is applicable to the heavy design that subtracts of various motorcycle types such as car, SUV.

Detailed Description
The front cross beam structure of the front floor of the present invention will be further described below with reference to specific embodiments to help those skilled in the art to understand the concept and technical solution of the present invention more completely, accurately and deeply.
Example 1
As shown in fig. 3 to 5, the present embodiment provides a front floor front cross member structure including a steel front floor 10, steel sill inner 20 disposed at both sides of the front floor 10, and an aluminum front cross member 30. As shown in fig. 4, the aluminum front cross member 30 has a structure like a Chinese character 'mu', is processed by conventional aluminum extrusion, and has simple process, low mold cost and good structural strength. As shown in fig. 5, L-shaped connecting plates 32 are provided on left and right sides of the aluminum front cross member 30, and the L-shaped connecting plates may be formed by bending and welded to the left and right sides of the aluminum front cross member 30, and the L-shaped connecting plates on the left and right sides are symmetrically provided. The two sides of the extruded aluminum front cross member 30 can be connected to the steel side rail inner panel by providing the L-shaped connecting plates 32. As shown in fig. 4, a seat mounting point is provided on the aluminum front cross member, and a steel threaded pipe 40 is provided at the seat mounting point, and the steel threaded pipe 40 is connected to the aluminum front cross member 30 by caulking. The front and rear sides of the aluminum front beam 30 are provided with flanges 31, as shown in fig. 4, the flanges 31 are connected with the front floor 10 through a self-piercing riveting structure 50, and fig. 6 shows details of the self-piercing riveting structure, which is a known cold connecting structure for connecting a steel plate and an aluminum plate. After a special rivet penetrates through a top layer plate by the aid of power provided by a hydraulic cylinder or a servo motor, a hollow structure at the tail of the rivet is expanded and pierced without penetrating through a bottom layer plate under the action of a riveting die, and the formed rivet is filled in the riveting die, so that a firm connection point is formed. As shown in fig. 7, the inner steel sill plate 20 and the L-shaped connecting plate 32 are connected by a self-piercing rivet structure.
The front floor front beam structure of this embodiment has adopted steel-aluminum mixed structure, has alleviateed whole weight, and the inside strengthening rib structure that is provided with the mesh font of front beam moreover, intensity is good, can resist bigger load when the side bumps, guarantees passenger's safety. The screwed pipe of the seat mounted position at the front beam connects the upper and lower both sides of front floor front beam through the mode of riveting, can provide the mounting point intensity better than original projection nut. The front floor front beam structure of the embodiment can be applied to weight reduction designs of various vehicle types such as cars, SUVs and the like.
For those skilled in the art, the specific embodiments are only exemplary descriptions of the present invention, and it is obvious that the present invention is not limited to the above-mentioned embodiments, and various insubstantial modifications can be made without modification to the method concept and technical solution of the present invention, and the present invention is also within the scope of the present invention.
