AI Technical Summary
Existing aluminum plates have poor buffering effect and insufficient impact resistance when subjected to external impacts. In particular, the arched block structure can only convert force in a small area, resulting in a limited effect.
A buffer mechanism is set inside the aluminum plate, including a support plate, a buffer ball, and a pneumatic tube. Multi-directional buffering is achieved through the conversion of the spherical thrust of the buffer ball and the gas compression of the pneumatic tube, increasing the stress points and buffering effect.
It effectively converts vertical impact force into multi-directional horizontal thrust, increases the number of stress points, and further reduces impact force through gas compression in the air pressure pipe, thereby improving impact resistance.

The production process covers pretreatment, coating, and high-temperature curing, taking into account functionality, decoration, and environmental protection. They are an important material for modern industry and construction.
[0003] Because aluminum sheets are relatively soft and easily deformed under external force, and have poor impact resistance, they are currently typically reinforced with arched blocks inside their internal layers to increase their impact resistance.
[0004] While the force-bearing structure formed by the shape of the arched blocks can convert vertical loads into horizontal thrust and transmit them to the arch foot along the arch thrust line to achieve a buffering effect, in actual use, the area where the aluminum plate is impacted is often small. That is, when an external force is impacted, the impacted area is small. The arched structure can only achieve a buffering effect through the conversion of force in a small area, and the direction of the converted force is unidirectional, so the effect is not good. Therefore, a buffer sandwich structure of impact-resistant lightweight color-coated aluminum coil is proposed to solve the above problems. Utility Model Content

[0031] The technical scheme in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model, and apparently, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the range of protection of the utility model.
[0032] Referring to Figure 1 With Figure 2 , the utility model provides an embodiment: a kind of buffer interlayer structure of impact resistance light weight color coated aluminium roll, including plate body 1, plate body 1 is light weight color coated aluminium roll, and the inside of plate body 1 is provided with cavity 2, by the setting of cavity 2, so that the quality of plate body 1 whole is lighter, and material consumption is less, reach the effect of reducing resource waste.
[0033] Referring to Figure 2 - Figure 4 The inside of the cavity 2 is provided with a buffering mechanism 3, which comprises a support plate 31 made of metal with high hardness. The support plate 31 is arranged in a position to ensure that it does not need to have the advantages of corrosion resistance and rich colors, but only needs to ensure the supporting effect of the plate body 1 through its own hardness. The outer wall of the support plate 31 is fixedly connected with the inner wall of the cavity 2. The front end of the support plate 31 is fixedly connected with a plurality of buffer balls I 32. The midpoint connecting line of the buffer balls I 32 forms a plurality of equilateral triangles. The rear end of the support plate 31 is fixedly connected with a plurality of buffer balls II 33. The buffer balls I 32 are hollow hemispheres. Through the shape of the buffer balls I 32, it is ensured that when the spherical surface is subjected to force, the force perpendicular to the spherical surface can move to the side close to the support plate 31 through the thrust line of the spherical surface, thereby achieving the buffering effect. The middle part of the buffer balls I 32 is thicker than the edge thickness. After the plate body 1 is subjected to external force, the inner wall first contacts the middle part of the buffer balls I 32. Therefore, the thicker middle part of the buffer balls I 32 can ensure the service life. The shape of the buffer balls II 33 is consistent with that of the buffer balls I 32. The number of the buffer balls II 33 is set to be multiple. The array mode of the buffer balls II 33 is consistent with that of the buffer balls I 32. The buffer balls II 33 are arranged at the center of the three buffer balls I 32 whose connecting line forms an equilateral triangle. Through the position arrangement, it is ensured that when one of the buffer balls I 32 is subjected to force, the three buffer balls II 33 close to it can be subjected to force, so that the stress point is increased, and the buffering effect is achieved.
[0034] Referring to Figure 3 - Figure 5The inner part of the support plate 31 is provided with a force blocking assembly 4, which comprises an air pressure pipe 41 arranged in the middle of the three buffer balls one 32 connected in an equilateral triangle, and also arranged in the middle of the three buffer balls two 33 connected in an equilateral triangle. The arrangement of the air pressure pipe 41 ensures that no matter where the plate body 1 is pressed, when the degree of pressing is sufficient, the force blocking assembly 4 can buffer it. The outer wall of the air pressure pipe 41 penetrates and is fixedly connected with the inner wall of the support plate 31. The inner wall of the air pressure pipe 41 is connected with a sliding plate one 42 through a piston. The end of the sliding plate one 42 away from the middle of the air pressure pipe 41 is fixedly connected with a pushing block one 43. The inner wall of the air pressure pipe 41 at the rear side of the sliding plate one 42 is connected with a sliding plate two 44 through a piston. The outer part of the sliding plate one 42 and the sliding plate two 44 is provided with a rubber coating. The outer wall of the sliding plate one 42 and the sliding plate two 44 is in close contact with the inner wall of the air pressure pipe 41. The arrangement of the rubber coating ensures that gas cannot leak from the position where the sliding plate one 42 or the sliding plate two 44 contacts the air pressure pipe 41. The rear end of the sliding plate two 44 is fixedly connected with a pushing block two 45. The pushing block one 43 and the pushing block two 45 are the same shape. The farthest distance between the pushing block one 43 and the pushing block two 45 is less than the farthest distance between the buffer ball one 32 and the buffer ball two 33. The side of the pushing block one 43 and the pushing block two 45 away from each other is arranged as an arc surface. The arrangement of the arc surface ensures that when the inner wall of the plate body 1 contacts the pushing block one 43 or the pushing block two 45, damage will not occur due to contact with sharp corners.
[0035] Working principle: when in use, after the outer part of the plate body 1 is subjected to an external force, the middle spherical surface of the buffer ball one 32 or the buffer ball two 33 subjected to the external force is first subjected to the force. Then, due to its shape, it can transmit the pushing force along the spherical surface to the end, thereby converting the force perpendicular to the plate body 1 into a force parallel to the plate body 1, achieving a buffering effect.
[0036] At the same time, when one of the buffer balls one 32 is subjected to a force, since there are three buffer balls two 33 on the other side of the support plate 31 opposite to it, the number of buffer balls two 33 participating in buffering can be increased, thereby increasing the buffering effect.
[0037] When the external force is greater, causing the buffer ball one 32 and the buffer ball two 33 to deform, and the projection length of the farthest distance between the two in the vertical direction of the plate body 1 after deformation is equal to or shorter than the farthest distance between the pushing block one 43 and the pushing block two 45, the pushing block one 43 and the pushing block two 45 are subjected to a force and move in the direction of pressing the gas inside the air pressure pipe 41, thereby buffering the force through the gas.
[0038] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, the spirit and principles of the present application, the made any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
