Sheet metal baffles are long strip-shaped metal parts with functions such as blocking, protection, and guidance, which are mainly made using sheet metal work.

[0003] A gap filler strip is a slender metal component made using sheet metal processing techniques, primarily used to fill or cover gaps between two objects. It is typically made by cutting, bending, and forming sheet metal sheets such as aluminum into strip-shaped structures that meet specific gap shape and size requirements.

[0004] However, traditional baffle sheet metal is a single piece. During use, the baffle sheet metal vibrates due to the vibration of the machine, which causes other parts to deform due to the weight of the baffle sheet metal. Utility Model Content

[0019] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] Reference Figure 1 - Figure 3The present invention provides an embodiment of a structure for preventing deformation of sheet metal in gap barriers, comprising a base sheet metal part 1, the base sheet metal part 1 having multiple honeycomb support structures 2 inside, the outer wall of the base sheet metal part 1 having a bending surface 4, the outer wall of the bending surface 4 having a smooth rolled edge 3, the honeycomb support structure 2 being used to enhance the uniform distribution of external forces, the bending surface 4 being able to prevent sharp edges from causing injury to the human body and other objects, the rolled edge 3 reducing the degree of stress concentration, and the outer wall of the rolled edge 3 being provided with a reinforcing support component, the reinforcing support component being used to enhance the stress-bearing capacity of the rolled edge 3.

[0021] Specifically, the base sheet metal part 1 is a high-strength aluminum alloy formed by adding appropriate amounts of copper and magnesium elements to aluminum alloy, which has higher yield strength and elastic modulus, increasing the yield strength of the base sheet metal part 1 by 20% to 50%. The base sheet metal part 1 has multiple honeycomb support structures 2 evenly distributed inside, ensuring that the structure has good resistance to deformation and significantly reduces weight. The rolled edge 3 increases the moment of inertia of the edge material, which greatly increases the moment of inertia of the edge, improving the edge's resistance to bending deformation by 30% to 50%. The reinforcing ribs 5 make the stress distribution more uniform throughout the structure, improving the overall resistance to deformation.

[0022] Reference Figure 1 - Figure 3 The reinforced support component includes a reinforcing rib 5, the outer wall of which is fixedly connected to the outer wall of the rolled edge 3. The reinforcing rib 5 is rectangular, and the reinforcing rib 5 and the rolled edge 3 work together to effectively prevent edge warping and bending deformation.

[0023] Specifically, the reinforcing rib 5 can make the stress distribution more uniform, and the rolled edge 3 enhances the moment of inertia of the edge part. Through the mutual assistance of the two, the effect of preventing edge warping and bending deformation can be effectively achieved.

[0024] Reference Figure 1 - Figure 3 The height of the reinforcing rib 5 is between one-quarter and one-third of the base sheet metal part 1, and the thickness of the reinforcing rib 5 is between one-third and one-half of the base sheet metal part 1.

[0025] Specifically, when the height of the reinforcing rib 5 is set between one-quarter and one-third of the height of the base sheet metal 1, the moment of inertia of the structure can be effectively increased. The thickness of the reinforcing rib 5 is set between one-third and one-half of the thickness of the base sheet metal 1, mainly to enhance its shear strength.

[0026] Reference Figure 1 - Figure 3 The thickness of the rolled edge 3 is two to three times the thickness of the base sheet metal part 1.

[0027] Specifically, when the thickness of the rolled edge 3 is increased to two to three times the thickness of the base sheet metal part 1, the bending strength of the edge portion will be significantly improved.

[0028] Reference Figure 1 - Figure 3 The basic sheet metal part 1 is composed of a high-strength aluminum alloy with appropriate amounts of copper and magnesium elements, which can increase the yield strength by 20% to 50%.

[0029] Specifically, aluminum alloys have low density. After adding appropriate amounts of copper and magnesium to form a high-strength alloy, they still maintain a relatively light weight. Furthermore, the atomic radius of copper is larger than that of aluminum, while the atomic radius of magnesium is smaller than that of aluminum. Their presence in the aluminum lattice will change the arrangement of the surrounding aluminum atoms, generating a local stress field, thereby improving the yield strength of the basic sheet metal part 1.

[0030] Working Principle: This structure is based on a basic sheet metal part 1, which is a high-strength aluminum alloy with appropriate amounts of copper and magnesium added. This material has higher yield strength and elastic modulus, increasing its yield strength by 20% to 50%, effectively enhancing the stability of the gap retainer under complex stress environments. The outer wall of the rolled edge 3, connected to the basic sheet metal part 1, is provided with a bending surface 4. The rolled edge 3 increases the moment of inertia of the edge material. The moment of inertia is an important indicator of an object's resistance to bending deformation. When the rolled edge 3 is set, it is equivalent to adding extra material thickness and width in the bending direction at the edge, which significantly increases the moment of inertia of the edge. After processing, the edge's resistance to bending deformation can be increased by 30% to 50%, effectively preventing the edge from curling or bending under external force. The smooth surface of the fold 4 prevents sharp edges from causing injury to the human body and other objects, scratching the user's skin or damaging items in contact with it, providing a safer user environment. The reinforcing ribs 5 can be arranged according to stress analysis, making the stress distribution more uniform throughout the structure and more balanced in various parts, thus improving the overall resistance to deformation. The base sheet metal part 1 has multiple honeycomb support structures 2 evenly distributed inside, which can reduce the weight to a large extent while ensuring good resistance to deformation. That is, this structure can not only reduce the weight to a large extent, but also have good resistance to deformation, and can also effectively prevent the edges from curling or bending under external force and avoid sharp edges from causing injury to the human body and other objects.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
