DETAILED DESCRIPTION OF THE INVENTION

The present invention is further described below in conjunction with drawings.
In embodiment 1, as shown in FIG. 1, a bulletproof structure of the present invention includes bulletproof bodies 1 and a bulletproof substrate 2, wherein the bulletproof bodies are spheres, and a plurality of bulletproof bodies 1 are uniformly bonded to the bulletproof substrate 2 through super glue a; as a production way, the bulletproof substrate can be preliminarily coated with super glue, then the bulletproof bodies are uniformly arranged on the super glue, and generally after the super glue is completely solidified, the bulletproof bodies can be bonded to the bulletproof substrate; the bulletproof bodies are generally compactly distributed, and about a half of the sphere is exposed out of the super glue; the bulletproof bodies and the bulletproof substrate can also be directly produced into a whole by using a mold when in production; in the present application, the bulletproof bodies can be made of the existing bulletproof structure material and can generally select two kinds of materials: metal material and nonmetal material, the metal material can use steel and iron, the surface is made smooth, and the nonmetal material uses ceramics and glass; and the bulletproof substrate can be made of the existing bulletproof structure material such as steel and iron. The spheres on the surface of the bulletproof substrate are made smooth.
According to the bulletproof structure provided by the invention, when bullets hit the bulletproof structure, the surfaces are arc-shaped surfaces, so that after the collision of the bullets, due to the space around the arc-shaped surface, the bullets are not supported, and the direction of the bullets are easily changed towards the outer side after the collision, thereby reducing the impact force, and achieving a protection effect. The bulletproof structure can also be named as a protection structure, and the application of the bulletproof structure is the same as that of the existing bulletproof structure, for example, the bulletproof structure can be directly made into bulletproof products such as riot shields, or the bulletproof substrate can be fixed on parts, requiring the bullet resistance, of car bodies, ship bodies and the like in a soldering way, a bolt connecting way, a hanging way and the like, which are not specifically limited herein
In embodiment 2, referring to FIG. 2, as a variant, the bulletproof bodies are hemispheres, the spherical ends of a plurality of bulletproof bodies 1 are uniformly fixed on the bulletproof substrate 2, and this structure can be used for resisting bullets with large impact force; and when the impact force is large, the hemispherical bulletproof bodies are easy to separate from the bulletproof substrate, the counterforce can change the running direction of the bullet, thereby reducing the impact force. The structure can also be applied to the situation requiring a smooth bulletproof structure.
In embodiment 3, referring to FIG. 3, as a variant, the bulletproof bodies 1 are hemispheres, and the plane ends of a plurality of bulletproof bodies 1 are uniformly fixed on the bulletproof substrate 2. By adopting the structure, the bottom of the bulletproof body is stable.
In embodiment 4, as a variant, referring to FIG. 4, one end of the bulletproof body 1 is a hemisphere, the other end is a cylinder, and the cylinder is connected to the bulletproof substrate 2. By adopting the structure, the thickness of the bulletproof structure can be appropriately reduced, and the thickness of the super glue can be increased, thereby improving the strength of the bulletproof structure and the firmness of the bulletproof bodies.
In embodiment 5, referring to FIG. 5, two ends of the bulletproof body 1 are hemispheres, the middle part is a cylinder, and the spherical ends of a plurality of bulletproof bodies 1 are uniformly connected to the bulletproof substrate 2. By adopting the structure, the direction of the bullet can be changed after hitting the bulletproof structure through the side surfaces of the cylinders, thereby reducing the impact force, and also increasing the thickness of the bulletproof structure.
In embodiment 6, as a preferred solution, referring to FIG. 6, the bulletproof body 1 includes a fixed part and hemispherical projections 12, wherein the fixed part is formed by integrally connecting a plurality of hollow elastic truncated-cone-shaped projections 11, the upper bottom surface, i.e. the bottom surface with a small diameter of the truncated-cone-shaped projection is connected with the plane end of the hemispherical projection, which can be molded integrally with a mold preparation during production; the side wall of the bottom hollow elastic truncated-cone-shaped projection is set to be slightly thin and to have elasticity, and a plate with the hollow elastic truncated-cone-shaped projection and a mold for holding a plurality of hemispherical projections can be separately used, and then the hollow elastic truncated-cone-shaped projections and the hemispherical projections can be bonded into a whole in one step by using the super glue, which is not specifically limited here. By using the structure, when the bullet hits the bulletproof structure, the arc-shaped surfaces can easily change the direction of the bullet, so that the impact force is reduced; and the hollow elastic truncated-cone-shaped projection is deformed, so that the direction of the bullet is easy to change, thereby reducing the impact force. In the actual production, the hollow elastic truncated-cone-shaped projection can also be set as a non-elastic hollow truncated-cone-shaped projection, when the impact force of the bullet is large, the hollow truncated-cone-shaped projection is first damaged, and the hemispherical projection moves down along a damaged part, thereby further making the bullet change the direction easily.
As a preferred solution, referring to FIG. 7, the bottom surface of the hemispherical projection, which also is the top inner surface of the hollow elastic truncated-cone-shaped projection, is fixedly provided with a protrusion part 13 extending towards the inner side of the hollow elastic truncated-cone-shaped projection, and the protrusion part deviates from the spherical center of the hemispherical projection. By adopting the structure, when the bullet vertically hits the center point of the hemisphere, and when the elastic truncated-cone-shaped projection 11 moves down, the protrusion part may first support the hemispherical projection on one side, the other side of the hemispherical projection continues to move down so as to be supported by the protrusion part to rotate, so that the movement direction of the bullet is changed, and the impact force is reduced; if the hollow elastic truncated-cone-shaped projection is fixed in a bonding way of super glue, the super glue can seal the bottom of a hollow part of the hollow elastic truncated-cone-shaped projection, when the elastic truncated-cone-shaped projection 11 moves down, the compressed air can play a certain buffering effect, after the movement direction of the bullet is changed and the direction of the impact force shifts, the buffering effect only aims at a component force of the impact force, and the buffering effect is better. As an arrangement way of the protrusion part, the protrusion parts can be arranged in a manner that the protrusion parts in the bulletproof bodies are alternately arranged on one side as shown in FIG. 7, can also be all arranged on one side as shown in FIG. 8, and can also be arranged on the walls of the elastic truncated-cone-shaped projections as shown in FIG. 9.
The bulletproof structure of the present invention is described above in a way of illustration with the drawings. Those skilled in the art shall understand that the present invention is not limited to the above-described embodiments, and various modifications, changes and replacements can be made without departing from the scope of the present invention.
