Description

Technical Field

[0001] The utility model belongs to the field of automobile structural reinforcements, and specifically relates to a structural reinforcement. Background Art

[0002] In the current new energy vehicle market, in order to achieve long driving range, car manufacturers have lower and lower requirements for the vehicle's own weight when designing cars. The requirements can only be met by reducing the thickness of sheet metal, but while reducing the thickness of sheet metal, its strength and safety performance need to be guaranteed; then structural reinforcements are used instead of sheet metal. Due to the material properties of the structural reinforcements themselves, the strength can only be met by thickening or increasing them; the current structural reinforcement designs are all triangles, diamonds, and rectangles inside, and the combination of these shapes will bring certain difficulties to the mold, and thin iron is prone to appear. This shape has a small area and uses a lot of materials, which cannot meet the further weight reduction needs of the existing market.

[0003] To address the aforementioned issues, Patent Document 221340804U discloses a structural reinforcement and an automobile. The reinforcement comprises a first metal structural member for insertion into a door pillar and a second metal structural member for insertion into a rocker beam. This improves the structural strength of the door pillar and rocker beam during an offset collision. The reinforcement also includes an expansion layer and a thermoplastic layer wrapped around each metal structural member, but this does not address the aforementioned issues.

[0015] The following is a further detailed description of the specific implementation methods of the present invention through the description of the embodiments with reference to the accompanying drawings, with the aim of helping those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention and to facilitate their implementation.

[0016] Figure 1 It is a cross-sectional view of a structural reinforcement member in an embodiment of the present utility model.

[0017] like Figure 1 As shown, the structural reinforcement provided by the present invention includes a skeleton 10 and a foaming layer 20. A support frame structure 11 is provided in the skeleton 10, and the support frame structure 11 can enhance the structural strength of the skeleton 10. The foaming layer 20 is filled in the skeleton 10. The foaming layer 20 is squeezed into between the support frame structure 11 and the skeleton 10 through the foaming material. After foaming, the foaming layer 20 is formed, which further improves the structural strength of the skeleton 10 and can meet the lightweight requirements of the vehicle body. The structural reinforcement provided by the present invention can meet the lightweight requirements of the vehicle body while further improving the structural strength of the vehicle body.

[0018] The support frame structure 11 includes a first support frame 111 and a second support frame 112. Figure 1As shown, the first support frame 111 is a hexagonal structure, which has the highest tightness, requires the least material, and can fill the largest space. Figure 1 As shown, the second support frame 112 is a circular structure. Through the cooperation between the first support frame 111 and the second support frame 112, the structural strength of the entire support frame 11 can be further improved, and the structural strength of the skeleton 10 can be further improved.

[0019] The foaming material is filled in the gaps between the first support frame 111, the second support frame 112, and the support frame structure 11 and the frame 10. After the foaming process is completed, the foaming material forms a foam layer 20, which further improves the structural strength of the frame 10 and meets the requirements for lightweighting the vehicle body. This allows the structural reinforcement provided by the present invention to meet the requirements for lightweighting the vehicle body while further improving the structural strength of the vehicle body. Epoxy resin can be used as the foaming material.

[0020] Connecting buckles 12 are provided on both sides of the frame 10. The connecting buckles 12 can conveniently connect the frames 10, provide an installation method between the frames 10, and facilitate the installation of the structural reinforcement provided by the present invention.
