Description
Technical Field
The invention relates to an automobile body, in particular to a middle row seat mounting structure in the automobile body.
Background
At present, on many passenger car bodies, the mounting point of a middle-row seat is usually arranged on the edge of a cross beam or the edge of the cross beam, if the mounting point is far away from the cross beam, the mounting point can be arranged in the small cross beam by adding a small cross beam between two cross beams, and thus the stress of the seat at the mounting point can be easily transferred to the cross beam, and the requirements of structural strength and rigidity are met.
The structure is widely applied to the body of a passenger car and has the advantages that: simple structure and mature technology. The disadvantages are: the mounting points are arranged in the beam or at the edge of the beam; under the condition that the seat mounting nut is stressed, the stress relation between the beam and other parts is mainly represented by stripping force, so that the failure risk of welding spots near the seat mounting nut is greatly improved.

FIG. 2 is a force-receiving schematic view of a mid-row seat mounting structure according to the present invention.
Fig. 3 is an exploded view of a mid-row seat mounting structure of the present invention.
Detailed Description
The invention is further described with reference to the following description of the drawings and detailed description.
As shown in fig. 1 to 3, a middle-row seat mounting structure includes a rear floor 1, a first middle-row seat reinforcement plate 2, a second middle-row seat reinforcement plate 3, seat mounting nuts 4, and a rear floor cross member 5, wherein the first middle-row seat reinforcement plate 2 is provided on the rear floor 1 and the rear floor cross member 5, respectively, the second middle-row seat reinforcement plate 3 is provided on the first middle-row seat reinforcement plate 2, and the seat mounting nuts 4 are provided on the second middle-row seat reinforcement plate 3.
As shown in fig. 1 to 3, the first middle-row seat reinforcing plate 2 is provided with a first flange 21, a second flange 22, a first boss 23, a second boss 24 and a first cavity 25, the first flange 21 is overlapped with the rear floor 1, the second flange 22 is overlapped with the rear floor cross beam 5, the first cavity 25 is located between the first boss 23 and the second boss 24, and the second middle-row seat reinforcing plate 3 is fixed in the first cavity 25.
As shown in fig. 1 to 3, the second middle-row seat reinforcement plate 3 is provided with a second cavity 33, a third flange 31 and a fourth flange 32, the third flange 31 is overlapped with the first boss 23, the fourth flange 32 is overlapped with the second boss 24, and the second cavity 33 is disposed in the first cavity 25.
As shown in fig. 1 to 3, the first middle-row seat reinforcement panel 2 has a double "table" shape.
As shown in fig. 1 to 3, the second middle-row seat reinforcement plate 3 has an inverted "table" shape.
The middle-row seat mounting structure provided by the invention has the following characteristics:
a. the two middle-row seat reinforcing plates (namely the first middle-row seat reinforcing plate 2 and the second middle-row seat reinforcing plate 3) are designed to form a closed cavity structure, are connected with the rear floor 1 and the rear floor cross beam 5, and transmit and diffuse force to the rear floor 1 and the rear floor cross beam 5 to meet the strength requirement of a seat mounting point.
b. The second middle-row seat reinforcing plate 3 is designed into a shape like a Chinese character 'ji', and the plane welded with the seat mounting nut 4 is designed to be minimum, so that the deformation of the periphery of the seat mounting nut 4 caused by stress is reduced, and the flanging is added on the periphery to strengthen the strength of the part; the first middle-row seat reinforcement plate 2 is designed into a double-n-shaped structure with a cavity, and extends to the rear floor cross member 5 to be connected with the same. The whole structural strength and rigidity are improved maximally by welding with the second middle-row seat reinforcing plate 3, the rear floor cross beam 5 and the rear floor 1.
c. The stress transmission process of the structure is shown in fig. 2: the force is transferred from the seat mounting nuts 4 to the second middle row seat reinforcement plate 3 and then from the second middle row seat reinforcement plate 3 to the first middle row seat reinforcement plate 2, and finally the force is dispersed to the rear floor 1 and the rear floor cross member 5, and the welding relationship of all welding spots does not generate stripping force. Specifically, through the reinforcing of the first middle row seat reinforcing plate 2 and the second middle row seat reinforcing plate 3 part structure, increase, transmit the force from the seat mounting nut 4 (F1) a stress point to the second middle row seat reinforcing plate 3 (F2), then by the first middle row seat reinforcing plate 2 (F3) transmit the dispersion to the back floor 1 and the back floor crossbeam 5, overlap joint between part and the part is when the welding, all solder joints do not appear the atress and peel off the condition to avoid this structure atress big, the atress destruction that solder joint stress produced is high.
The middle-row seat mounting structure provided by the invention has the following advantages:
1. whether the seat mounting point is arranged in the beam or at the edge is not considered, and the arrangement range is enlarged; .
2. The beam is arranged at a position far away from the beam, and the strength requirement can be met without adding a small longitudinal beam.
3. Reducing the strain of the luggage compartment during the belt pull test.
4. The local rigidity of the mounting point of the seat is improved.
The foregoing is a further detailed description of the invention in connection with the preferred embodiments, and it is not intended that the invention be limited to the specific embodiments described.
