Specific embodiment 1

[0032] See also Figure 1-6 The utility model is a new material plastic plate for noise absorption, collision prevention and buffering, comprising a lower plate 1, an upper plate 2 is arranged on the top of the lower plate 1, a sound-absorbing cotton 3 is arranged in the inner cavity of the upper plate 2, a rubber pad 4 is arranged on the top of the upper plate 2, and a buffer mechanism 5 is arranged in the inner cavity of the lower plate 1;

[0033] The buffer mechanism 5 comprises a movable plate 51, a spring 52 is fixedly connected to the bottom of the movable plate 51, and a damper 53 is fixedly connected to the bottom of the inner cavity of the lower plate 1;

[0034] The lower plate 1 includes a substrate 12 , a surface of the substrate 12 is coated with a heat insulating layer 13 , a side of the heat insulating layer 13 away from the substrate 12 is coated with a weather resistant layer 14 , and a side of the weather resistant layer 14 away from the heat insulating layer 13 is coated with a wear resistant layer 15 .

[0035] Specifically: the upper plate 2 can be protected by the rubber pad 4. When an external object hits, the rubber pad 4 can well buffer the impact force. At the same time, the sound-absorbing cotton 3 can well absorb the noise, thereby achieving the effect of noise prevention. Then the impact force drives the rubber pad 4 and the upper plate 2 downward, so that the upper plate 2 drives the movable plate 51 downward to cause compression deformation of the damper 53 and the spring 52, thereby initially buffering the impact force. At the same time, the reset force of the damper 53 and the spring 52 can drive the movable plate 51 and the upper plate 2 to reset, thereby The impact force is offset, thereby improving the anti-collision performance of the lower plate 1 and the upper plate 2. At the same time, a hard surface protection layer can be formed through the wear-resistant layer 15 to improve the hardness and durability of the lower plate 1 and the upper plate 2. The weather-resistant layer 14 can increase the durability and corrosion resistance of the lower plate 1 and the upper plate 2. The heat-insulating layer 13 has excellent heat-insulating performance and can form an efficient heat-insulating coating to reduce heat conduction and heat radiation, thereby improving the high temperature resistance of the lower plate 1 and the upper plate 2 and preventing the lower plate 1 and the upper plate 2 from softening and deforming due to high temperature. Specific embodiment 2

[0037] See also Figure 1-6 On the basis of the specific embodiment 1, the heat insulation layer 13 adopts a nano-aluminum oxide coating, the weather-resistant layer 14 adopts an acrylic coating, and the wear-resistant layer 15 adopts a silicon coating; the lower plate 1 also includes a limit groove 11, and the limit groove 11 is opened on both sides of the front and back of the inner cavity of the lower plate 1, and both sides of the front and back of the movable plate 51 are fixedly connected with the limit block 511, and the limit block 511 extends from one end of the movable plate 51 to the inner cavity of the limit groove 11, and is slidably connected to the inner cavity of the limit groove 11.

[0038] Specifically: the silicon coating has high hardness and wear resistance, and can form a hard surface protection layer, thereby improving the hardness and durability of the lower plate 1 and the upper plate 2; the acrylic coating has good weather resistance and corrosion resistance, thereby increasing the durability and corrosion resistance of the lower plate 1 and the upper plate 2; the nano-alumina has excellent thermal insulation performance, and can form an efficient thermal insulation layer to reduce heat conduction and thermal radiation, thereby improving the high temperature resistance of the lower plate 1 and the upper plate 2, and preventing the lower plate 1 and the upper plate 2 from softening and deforming due to high temperature; when the movable plate 51 moves up and down, the movable plate 51 drives the limit block 511 to move along the inner cavity trajectory of the limit groove 11, thereby ensuring the stability of the movement of the movable plate 51 and preventing the movable plate 51 from being dislocated during movement. Specific embodiment three

[0040] See also Figure 1-6 On the basis of the first and second embodiments, screw holes 21 are provided around the top of the upper plate 2, screws 41 are movably connected around the top of the rubber pad 4, the bottom of the screw 41 extends to the inner cavity of the screw hole 21, and is threadedly connected to the inner cavity of the screw hole 21; positioning grooves 22 are provided on both sides of the top of the upper plate 2, and positioning blocks 42 are fixedly connected on both sides of the bottom of the rubber pad 4, the bottom of the positioning block 42 extends to the inner cavity of the positioning groove 22, and is threadedly connected to the inner cavity of the positioning groove 22. The sound-absorbing cotton 3 is located in the inner cavity of the upper plate 2 and is movably connected to the inner cavity of the upper plate 2. The bottom of the rubber pad 4 extends to the inner cavity of the upper plate 2 and contacts the top of the sound-absorbing cotton 3. The rear end of the inner cavity of the upper plate 2 is fixedly connected to the limit strip 23, and the back of the sound-absorbing cotton 3 contacts the front of the limit strip 23. The top of the damper 53 is fixedly connected to the movable plate 51, the top of the movable plate 51 is fixedly connected to the upper plate 2, and the bottom of the spring 52 is fixedly connected to the bottom of the inner cavity of the lower plate 1.

[0041] Specifically: by rotating the screw 41, the screw 41 gradually enters the inner cavity of the screw hole 21 downward, so that the screw 41 is threadedly connected with the screw hole 21, thereby realizing a firm connection between the rubber pad 4 and the upper plate 2, and the rubber pad 4 can well press and position the sound-absorbing cotton 3. When the rubber pad 4 is connected to the upper plate 2, the rubber pad 4 drives the positioning block 42 downward, so that the positioning block 42 gradually enters the inner cavity of the positioning groove 22, thereby limiting the rubber pad 4 to prevent the upper plate 2 and the rubber pad 4 from being misaligned. The back of the sound-absorbing cotton 3 contacts the limiting strip 23, and then the limiting strip 23 can limit the sound-absorbing cotton 3 to prevent the sound-absorbing cotton 3 from being misaligned in the inner cavity of the upper plate 2.

[0042] The working principle of the utility model is as follows: first, the upper plate 2 can be protected by the rubber pad 4. When an external object collides, the rubber pad 4 will be in direct contact with the external object, so that the external object will not directly collide with the upper plate 2. The impact force can be well buffered by the rubber pad 4, and at the same time, the sound-absorbing cotton 3 can absorb the noise well, thereby achieving the effect of noise prevention. Then the impact force will drive the rubber pad 4 and the upper plate 2 downward, so that the upper plate 2 drives the movable plate 51 downward to cause extrusion deformation of the damper 53 and the spring 52. The impact force can be initially buffered by the extrusion of the damper 53 and the spring 52. At the same time, the movable plate 51 and the upper plate 2 can be reset by the reset force of the damper 53 and the spring 52, and then the reset force can be used to The impact force is offset to improve the anti-collision performance of the lower plate 1 and the upper plate 2. When the lower plate 1 and the upper plate 2 are in use, a hard surface protection layer can be formed through the wear-resistant layer 15 to improve the hardness and durability of the lower plate 1 and the upper plate 2, and effectively prevent the lower plate 1 and the upper plate 2 from being worn by friction from external objects. The weather-resistant layer 14 has good weather resistance and corrosion resistance, thereby improving the durability and corrosion resistance of the lower plate 1 and the upper plate 2. The heat-insulating layer 13 has excellent heat-insulating performance and can form an efficient heat-insulating coating on the surface of the lower plate 1 and the upper plate 2 to reduce heat conduction and heat radiation, thereby improving the high temperature resistance of the lower plate 1 and the upper plate 2 and preventing the lower plate 1 and the upper plate 2 from softening and deforming due to high temperature.
