Description

Technical Field

[0001] This utility model relates to the field of sheet metal structure technology, and in particular to a sheet metal impact-resistant structure and testing device. Background Technology

[0002] Impact-resistant sheet materials typically improve their impact resistance by enhancing the material's inherent impact resistance and through rational design. By layering different materials together to form a composite structure, the overall impact resistance of the sheet material is enhanced. Impact-resistant sheet materials and testing devices are used to test and improve the strength and durability of sheet materials under impact, and are commonly used in the automotive, aerospace, construction, and electronics industries.

[0003] However, existing plate impact resistance structures and testing devices suffer from insufficient material synergy during use. The difference in thermal expansion coefficients of different materials in the composite structure leads to stress concentration at the interface, which can easily cause delamination after long-term use, and the dynamic impact response is limited.

[0009] As a further embodiment of this utility model, the reinforcing rib is made of high-strength alloy steel, and the positioning cap is made of hardened steel. The positioning cap serves to match and limit the position of the reinforcing rib.

[0014] (III) Beneficial Effects

[0015] This utility model provides an impact-resistant structure and testing device for sheet metal, which has the following beneficial effects:

[0016] 1. The impact-resistant structure and testing device of this board, through the setting of honeycomb layers and reinforcing components, when in use, the honeycomb layer adopts a steel honeycomb structure. Its regular hexagonal honeycomb holes can effectively disperse pressure and reduce the overall weight, while maintaining high strength characteristics. When the toothed sandwich layer one and toothed sandwich layer two are compressed, they form a composite structure by increasing the contact area, which evenly distributes the local impact load to a larger area, avoids rapid failure caused by stress concentration, and improves the overall impact resistance of the board. At the same time, reinforcing ribs are added inside the board. These reinforcing ribs help to disperse the impact force and prevent the board from bending or cracking excessively during impact. Through the combined application of multiple structures, the board has both lightweight and impact resistance.

[0017] 2. The impact-resistant structure and testing device of this board, through the setting of protective components, when in use, the buffer layer is made of polystyrene board, which absorbs impact energy through its porous structure. The protective layer is made of polyethylene, which provides the overall surface of the board with anti-penetration capability and can resist the penetration of sharp objects. At the same time, it forms a rigid-flexible composite structure with the buffer layer to avoid the rebound of impact energy. In addition, the fireproof column is made of mica-reinforced composite material, which provides passive fire protection for the board and ensures the structural integrity under high temperature.

[0024] Please see Figures 1 to 4 This utility model provides a technical solution: an impact-resistant structure and testing device for sheet metal, including a honeycomb layer 1 made of aluminum alloy. The honeycomb layer 1 effectively disperses pressure and reduces overall weight. A toothed interlayer 2 is fixedly connected to the top and bottom surfaces of the honeycomb layer 1. A second toothed interlayer 3 engages with the surface of the first toothed interlayer 2. Both the first toothed interlayer 2 and the second toothed interlayer 3 are made of carbon fiber composite material. Several sets of reinforcing components 4 are nested inside the second toothed interlayer 3. A partition 5, made of fiberglass composite board, is fixedly connected to the surface of the second toothed interlayer 3.

[0025] The reinforcing component 4 includes a reinforcing rib 401 sleeved inside the toothed interlayer 3, with positioning caps 402 sleeved at both ends of the reinforcing rib 401. The reinforcing rib 401 is made of high-strength alloy steel, and the positioning caps 402 are made of hardened steel. The positioning caps 402 serve to match and limit the movement of the reinforcing rib 401.

[0026] The protective component 6 includes a buffer layer 601 fixedly connected to the surface of the partition 5. A protective layer 602 is fixedly connected to the surface of the buffer layer 601. The protective layer 602 is made of polyethylene. Several sets of fireproof columns 7 are arranged inside the honeycomb panel layer 1. The fireproof columns 7 are made of mica-reinforced composite material. The fireproof columns 7 provide passive fire protection for the panels. The buffer layer 601 is made of polystyrene board.

[0029] In this invention, the working steps of the device are as follows:

[0030] First step: When in use, the honeycomb panel 1 adopts a steel honeycomb structure. Its regular hexagonal honeycomb holes can effectively disperse pressure and reduce the overall weight, while maintaining high strength characteristics. When the toothed sandwich layer 1 2 and toothed sandwich layer 2 3 are squeezed, they form a composite structure by increasing the contact area, which evenly distributes the local impact load to a larger area, avoids rapid failure caused by stress concentration, and improves the overall impact resistance of the panel. At the same time, reinforcing ribs 401 are added inside the panel. These reinforcing ribs 401 help to disperse the impact force and prevent the panel from bending or cracking excessively during impact. Through the combined application of multiple structures, the panel has both lightweight and impact resistance.

[0031] The second step: When in use, the buffer layer 601 is made of polystyrene board, which absorbs impact energy through its porous structure. The protective layer 602 is made of polyethylene, which provides the entire board with surface penetration resistance and can resist penetration by sharp objects. At the same time, it forms a rigid-flexible composite structure with the buffer layer to avoid the rebound of impact energy. The fireproof column 7 is made of mica-reinforced composite material, which provides passive fire protection for the board and ensures the structural integrity at high temperatures.
