Abstract
Description
Technical Field
[0001] The utility model relates to an automobile component, in particular to an automobile seat mounting bracket. Background Art
[0002] As an important part of the vehicle, the seat is fixed to the seat mounting bracket by bolts. The seat bracket is connected to the vehicle body floor system through welding points or welds. In addition to providing good support for the occupants, the seat also plays a positioning role during a vehicle collision, thereby protecting the occupants from injury. Therefore, the design of the mounting bracket for installing the seat is crucial. If the structural design of the bracket is unreasonable, the rigidity and strength are insufficient, it is easy to cause the seat mounting point to deform excessively or even fail during a vehicle collision, which will fail to fix and support the occupants, causing harm to the occupants, and having a certain impact on human life and property safety, which is easy to cause customer complaints. There are many ways to improve the rigidity of the seat mounting bracket: increasing the material grade of the seat mounting bracket sheet metal and increasing the thickness of the plate material. The higher the material grade and thickness, the more difficult it is to form, and it is prone to forming cracking problems, which requires high forming technology; increasing the material grade of the seat mounting bracket sheet metal and increasing the thickness of the plate material. Although this solution can improve the overall and local rigidity, it does not increase the cross-sectional area of the central channel due to the overlap with the central channel, and the bending and torsional performance of the central channel is not significantly improved, and the force transmission path during side collision is not strengthened. Utility Model Content
[0003] To address the problems existing in the prior art, the present invention provides a seat mounting bracket featuring a simple, one-piece structural design. The bracket spans the central tunnel and is welded to the central tunnel and floor crossbeam via weld points and seams. This effectively improves the bending and torsional resistance of the central tunnel's cross-section, enhancing both overall and local mounting point rigidity and strength. This allows for more effective force transmission in the event of a side collision, thereby protecting and supporting occupants and preventing injury to occupants caused by excessive deformation or even failure of the seat mounting points, which could have a certain impact on human life and property safety. Compared to the prior art, the bracket offers increased structural strength, a more stable force transmission path, a simpler structure, reduced mold development, and lower costs.

[0006] It also includes a bracket reinforcement plate, which includes a reinforcement plate body and a reinforcement plate folded edge formed by bending from the edge of the reinforcement plate body to one side. The bracket reinforcement plate is located at both ends of the groove space and is welded to the bracket body.
[0007] The reinforcing plate folding edge is also provided with a lug integrally formed with the reinforcing plate folding edge.
[0008] The outermost side of the short folded edge in the extending direction is provided with a bottom flange for welding to the automobile floor seat crossbeam.
[0009] Two reinforcing ribs are provided on the short folded edge, and the reinforcing ribs are arranged along the extending direction of the short folded edge.
[0010] The middle portion of the bracket body plate is provided with an elliptical boss, and the elliptical boss protrudes from the bottom surface of the bracket body plate toward the protruding side of the long folded edge or the short folded edge.
[0011] Seat mounting holes are provided in the centers of both ends of the bracket body plate.

[0029] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and do not constitute a limitation of the present invention.
[0030] The utility model provides a seat mounting bracket, comprising a bracket body 1 and a bracket reinforcement plate 2.
[0031] The structure of the bracket body 1 is as follows Figure 1 As shown, the bracket body 1 has a bracket body plate 11, the bracket body plate 11 has two opposite long sides and two opposite short sides, the edges of the long sides and the short sides are folded toward the same side of the bracket body plate 11 to form a long folded edge 13 and a short folded edge 14, and the two opposite long folded edges 13 and the two opposite short folded edges 14 enclose a groove space.
[0032] A folding notch 130 is formed in the middle of the long folding edge 13 for crossing the central channel 4 of the vehicle floor. The top and both sides of the folding notch 130 are respectively provided with a top flange 131 and a side flange 132 for welding to the central channel 4 of the vehicle floor. Figure 4 As shown, when the bracket body 1 is installed, it straddles the central channel 4 of the vehicle floor through the folding notch 130 and is then welded to the central channel 4 through the top flange 131 and the side flange 132 .
[0033] In order to facilitate welding and reduce stress concentration after welding, an arc notch 133 is provided at the junction of the top flange 131 and the side flange 132 .
[0034] The outermost side of the short folding edge 14 in the extending direction is provided with a bottom flange 141 for welding to the car floor seat crossbeam 3. Two reinforcing ribs 142 are provided on the short folding edge 14, and the reinforcing ribs 142 are arranged along the extending direction of the short folding edge 14.
[0035] like Figure 4 As shown, after the bracket body 1 straddles the central channel 4 of the vehicle floor through the folding notch 130, the bottom flange 141 is located on the seat crossbeam 3 of the vehicle floor, and the bottom flange 141 is connected to the seat crossbeam 3 of the vehicle floor by welding.
[0036] The bracket body 1 is welded to the central channel 4 and the floor crossbeam 3 in the above-mentioned manner, which effectively improves the bending and torsional resistance of the cross section of the central channel, and improves the rigidity and strength of the overall and local installation points. When the vehicle collides sideways, it can more effectively transmit force, thereby protecting and supporting the occupants, avoiding injury to the occupants due to excessive deformation or even failure of the seat installation points, which has a certain impact on human life and property safety.
[0037] The structure of the bracket reinforcement plate 2 is as follows Figure 2 As shown, the bracket reinforcement plate 2 includes a reinforcement plate body 21 and a reinforcement plate fold 22 formed by bending the edge of the reinforcement plate body 21 to one side. Figure 3 As shown, the bracket reinforcement plates 2 are located at both ends of the groove space of the bracket body 1 and are welded to the bracket body 1. The provision of the bracket reinforcement plates 2 can improve the strength of the bracket body 1.
[0038] The reinforcing plate folded edge 22 is further provided with a lug 221 integrally formed with the reinforcing plate folded edge 22 .
[0039] In order to further improve the strength of the bracket body 1 , the middle portion of the bracket body plate 11 has an elliptical boss 113 , which protrudes from the bottom surface of the bracket body plate 11 toward the extended side of the long folded edge 13 or the short folded edge 14 .

After the bracket reinforcement plate 2 is welded to the bracket body 1, the projection nuts 211 and the seat mounting holes 112 form a mounting channel for the seat. Bolts are inserted through these channels to secure the seat.
