[0045] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0046] The present invention also discloses a method for preparing a bulletproof plate, comprising the following steps:

[0047] Step 1. First, the support layer 101, the buffer layer 102 and the bulletproof layer 103 composed of the bulletproof plate body 1 are evenly positioned and inserted along the positioning hole 201 through the positioning rod 2 on the support layer 101. Specifically, the buffer layer 102 is inserted into the positioning rod 2 on the support layer 101 through the positioning hole 201, and then the bulletproof layer 103 is inserted along the positioning rod 2. Finally, the support layer 101, the buffer layer 102 and the bulletproof layer 103 are locked and installed by the bolts 104 at the four ends of the bulletproof layer 103, so that they can be replaced when a single component is damaged. When the bulletproof layer 103, the buffer layer 102 or one of the support layer 101 is damaged, there is no need to replace the entire bulletproof plate, and only the damaged component needs to be removed.

[0048] Step 2, then the four ends of the bulletproof layer 103 are provided with bolts 104 for locking the supporting layer 101 and the buffer layer 102, and the supporting layer 101, the buffer layer 102 and the bulletproof layer 103 are locked and fixed. Specifically, the bulletproof plate body 1 as a whole adopts a multi-layer composite structure, including a bulletproof layer 103, a buffer layer 102 and a supporting layer 101. The bulletproof layer 103 adopts a high-strength and high-toughness bulletproof material, such as silicon carbide ceramics, aramid fiber, etc., which is used to directly resist the impact of bullets and other ammunition. The buffer layer 102 adopts a lightweight and highly elastic material, such as polyurethane foam, rubber, etc., which is used to absorb and disperse impact energy. The supporting layer 101 adopts a high-strength and lightweight metal material, such as titanium alloy, aluminum alloy, etc., which is used to provide stability and support for the overall structure to ensure that it will not be deformed or damaged due to external force during use.

[0049] Step 3, finally, the side bulletproof plate 603 can be slid out along the guide slot block 301 through the push assembly to protect both sides. Specifically, a protrusion is provided on one side of the push block 501 close to the mounting seat 3, which is slidably connected to the positioning slot 502 to ensure the stability of the push block 501 during lifting and sliding. The inner wall of the guide slot block 301 is fixedly connected with a reinforcing rod 302. The guide slot blocks 301 on both sides of the mounting seat 3 are supported by the reinforcing rod 302 to ensure the stability of the guide slot block 301.

Then, when the push block 501 is lifting and lowering, the slide bar 402 is moved by the movable rod 503 on both sides. The rotating shaft at the end is rotationally connected with the push block 501, and the sliding bar 402 is pushed by the movable rod 503, so that the sliders 401 at both ends of the sliding bar 402 slide along the slide groove 4, and finally the sliding of the slider 401 drives the movable block 6 to slide inside the mounting seat 3. When the two groups of movable blocks 6 inside the mounting seat 3 move away from each other, the movable block 6 pushes the side bulletproof plate 603 on the guide block 602, and then the side bulletproof plate 603 is rotationally connected with the connecting block 601 on the movable block 6 through the rotating shaft. When the side bulletproof plate 603 is pushed by the movable block 6, the side bulletproof plate 603 slides outward along the guide groove block 301, and the side bulletproof plate 603 protects both sides at the extensions on both sides of the bulletproof plate body 1.

Specifically, the buffer layer 102 is inserted into the positioning rod 2 on the support layer 101 through the positioning hole 201, and then the bulletproof layer 103 is inserted along the positioning rod 2. Finally, the support layer 101, the buffer layer 102 and the bulletproof layer 103 are locked and installed by the bolts 104 at the four ends of the bulletproof layer 103;

[0051] Then the bulletproof plate body 1 as a whole adopts a multi-layer composite structure, including a bulletproof layer 103, a buffer layer 102 and a support layer 101. The bulletproof layer 103 adopts a high-strength and high-toughness bulletproof material, such as silicon carbide ceramics, aramid fiber, etc., for directly resisting the impact of bullets and other ammunition. The buffer layer 102 adopts a lightweight and highly elastic material, such as polyurethane foam, rubber, etc., for absorbing and dispersing impact energy. The support layer 101 adopts a high-strength and lightweight metal material, such as titanium alloy, aluminum alloy, etc., for providing stability and support force of the overall structure to ensure that it will not be deformed or damaged due to external forces during use;

[0052] When in use, the side bulletproof plate 603 can be slid out along the guide slot block 301 through the push assembly to provide protection on both sides. Specifically, a protrusion is provided on one side of the push block 501 close to the mounting seat 3, which is slidably connected to the positioning slot 502 to ensure the stability of the push block 501 when it is lifted and slid. The inner wall of the guide slot block 301 is fixedly connected with a reinforcing rod 302. The guide slot blocks 301 on both sides of the mounting seat 3 are supported by the reinforcing rod 302 to ensure the stability of the guide slot block 301. The electric push rod 5 drives the push block 501 to lift and lower along the positioning slot 502 on the mounting seat 3. Then, when the push block 501 is lifted and lowered, the slide bar 402 is moved by the movable rod 503 on both sides. The rotating shaft at the end is rotationally connected with the push block 501, and the sliding bar 402 is pushed by the movable rod 503, so that the sliders 401 at both ends of the sliding bar 402 slide along the slide groove 4, and finally the sliding of the slider 401 drives the movable block 6 to slide inside the mounting seat 3. When the two groups of movable blocks 6 inside the mounting seat 3 move away from each other, the movable block 6 pushes the side bulletproof plate 603 on the guide block 602, and then the side bulletproof plate 603 is rotationally connected with the connecting block 601 on the movable block 6 through the rotating shaft. When the side bulletproof plate 603 is pushed by the movable block 6, the side bulletproof plate 603 slides outward along the guide groove block 301, and the side bulletproof plate 603 protects both sides at the extensions on both sides of the bulletproof plate body 1.
