Description

Technical Field

[0001] This utility model relates to the field of side guard plate technology, and in particular to a sound-insulating and impact-resistant PP side guard plate. Background Technology

[0002] Side guards are devices used to protect the sides of equipment, vehicles, buildings, and other objects. They are typically made of materials such as metal, plastic, and carbon fiber. For example, engine side guards protect the sides of a car engine from external impacts and damage, reducing engine damage caused by collisions or other external factors during vehicle operation. They also have a certain decorative function. In the mining equipment field, side guards in hydraulic supports of fully mechanized coal mining faces are generally divided into fixed and movable types. Their main function is to block debris and protect pedestrian safety. They also help prevent the supports from tipping over when using side-push jacks. Chassis side guards protect vehicle chassis components such as drive shafts, suspension systems, oil lines, and wiring from impacts and scratches from road bumps, stones, etc.

[0003] In existing technologies, traditional side panels used in vehicle bodies have relatively weak impact resistance. When a vehicle is scraped, the doors and fenders are easily deformed, resulting in high repair costs. Furthermore, engine noise, tire noise, and wind noise are transmitted into the vehicle through the side panels, increasing cabin noise levels and potentially causing driver fatigue and distraction during long drives. Additionally, if the high-frequency noise from electric vehicle motors is not blocked by the side panels, it will exacerbate cabin noise and negatively impact passenger experience. Utility Model Content

[0004] The purpose of this invention is to solve the problem that traditional side guards have weak impact resistance and noise reduction capabilities in the existing technology, and to propose a sound-insulating and impact-resistant PP side guard.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a sound-insulating and impact-resistant PP side guard plate, comprising a guard plate body, a base layer disposed inside the guard plate body, a low-density layer fixedly installed on the top of the base layer, a high-density layer fixedly installed on the top of the low-density layer, an energy-absorbing layer fixedly installed on the top of the high-density layer, and a wear-resistant layer disposed on the top of the energy-absorbing layer.

[0006] Preferably, the top of the protective plate body has multiple evenly distributed placement slots, the inner wall of the placement slots is fixedly installed with magnets, an iron plate is slidably installed inside the placement slots, and an anti-collision strip is fixedly installed on the top of the iron plate.

[0007] Preferably, mounting holes are provided at all four corners of the top of the protective plate body.

[0008] Preferably, a flame-retardant layer is fixedly installed on the top of the energy-absorbing layer, and a waterproof and moisture-proof layer is fixedly installed between the flame-retardant layer and the wear-resistant layer.

[0009] Preferably, the flame-retardant layer has a thickness of 0.8 mm to 1 mm, and the waterproof and moisture-proof layer has a thickness of 0.3 mm to 0.5 mm.

[0010] Preferably, the outer wall of the iron plate is in contact with the inner wall of the placement groove.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. In this utility model, the low-density layer is made of polyurethane porous foam to absorb low-frequency noise (such as engine noise), and the high-density layer is made of PET fiber cotton to absorb high-frequency noise (such as tire friction noise). Both are environmentally friendly, formaldehyde-free, and resistant to aging. The energy-absorbing layer is made of carbon fiber reinforced polymer. Through physical deformation, structural damage, or energy dissipation of the material, it converts external impact energy (such as kinetic energy, vibration energy) into thermal energy, elastic potential energy, or other forms of energy, thereby reducing the damage to the target object from the impact. The combination of the low-density layer, high-density layer, and energy-absorbing layer improves the sound insulation and impact resistance of the main body of the protective panel.

[0013] 2. In this utility model, when an impact occurs, the object first comes into contact with the anti-collision strip. At this time, the anti-collision strip can effectively protect the main body of the guard plate, reducing the probability of damage to the main body of the guard plate. When the anti-collision strip is damaged, the staff can pull the anti-collision strip to remove the iron plate from the placement groove and replace it with a new anti-collision strip. The iron plate is inserted into the placement groove and is attracted to the outer wall of the magnet. The replacement can be completed in this way, which improves the replacement efficiency and reduces the cost of use. Attached Figure Description

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] Example 1, as Figures 1-4 As shown, this utility model provides a sound-insulating and impact-resistant PP side guard plate, including a guard plate body 1, a base layer 7 is provided inside the guard plate body 1, a low-density layer 8 is fixedly installed on the top of the base layer 7, a high-density layer 9 is fixedly installed on the top of the low-density layer 8, an energy-absorbing layer 10 is fixedly installed on the top of the high-density layer 9, and a wear-resistant layer 13 is provided on the top of the energy-absorbing layer 10.

[0022] The overall effect of Embodiment 1 is that the low-density layer 8 is made of polyurethane porous foam, used to absorb low-frequency noise (such as engine roar), and the high-density layer 9 is made of PET fiber cotton, used to absorb high-frequency noise (such as tire friction noise), and is environmentally friendly, formaldehyde-free, and resistant to aging. The energy-absorbing layer 10 is made of carbon fiber reinforced polymer, which converts external impact energy (such as kinetic energy, vibration energy) into heat energy, elastic potential energy, or other forms of energy through physical deformation, structural damage, or energy dissipation of the material, thereby reducing the damage of the impact force to the target object. Through the setting of the low-density layer 8, the high-density layer 9, and the energy-absorbing layer 10, the sound insulation and impact resistance of the main body of the protective panel 1 are improved.

[0023] Example 2, as Figures 1-4 As shown, further, the top of the protective plate body 1 has multiple evenly distributed placement slots 4, the inner wall of the placement slot 4 is fixedly installed with magnets 5, the inside of the placement slot 4 is slidably installed with iron plates 6, and the top of the iron plates 6 is fixedly installed with anti-collision strips 2. When the worker inserts the iron plates 6 into the placement slots 4, the iron plates 6 are attracted to the outer wall of the magnets 5, and the installation is completed.

[0024] Furthermore, mounting holes 3 are provided through the four corners of the top of the protective plate body 1 for workers to install the protective plate body 1.

[0025] Furthermore, a flame-retardant layer 11 is fixedly installed on top of the energy-absorbing layer 10, and a waterproof and moisture-proof layer 12 is fixedly installed between the flame-retardant layer 11 and the wear-resistant layer 13. The flame-retardant layer 11 is made of decabromodiphenyl ether, which prevents or slows down the spread of flames, buying time for personnel evacuation, equipment protection, or fire extinguishing. The waterproof and moisture-proof layer 12 is made of EPDM rubber, which has high elasticity and weather resistance, can adapt to the deformation of the side panel caused by temperature changes, avoids cracking and leakage, and is resistant to chemical corrosion, making it suitable for outdoor or humid environments.

[0026] Furthermore, the flame retardant layer 11 has a thickness of 0.8 mm to 1 mm, and the waterproof and moisture-proof layer 12 has a thickness of 0.3 mm to 0.5 mm.

[0027] Furthermore, the outer wall of the iron plate 6 is in contact with the inner wall of the placement groove 4 to prevent the iron plate 6 from shaking inside the placement groove 4.

[0028] The effect achieved by the entire embodiment 2 is that when an impact occurs, the object first comes into contact with the anti-collision strip 2. At this time, the anti-collision strip 2 can effectively protect the main body 1 of the protective plate, reducing the probability of damage to the main body 1 of the protective plate. When the anti-collision strip 2 is damaged, the staff can pull the anti-collision strip 2 to pull the iron plate 6 out of the placement groove 4, replace the new anti-collision strip 2, insert the iron plate 6 into the placement groove 4, and the iron plate 6 is attracted to the outer wall of the magnet 5. In this way, the replacement can be completed, improving the replacement efficiency and reducing the use cost.

[0029] Working Principle: The base layer 7 is made primarily of polypropylene with added glass fiber to enhance rigidity and impact resistance. The low-density layer 8 is made of porous polyurethane foam to absorb low-frequency noise (such as engine noise). The high-density layer 9 is made of PET fiber cotton to absorb high-frequency noise (such as tire friction noise), and is environmentally friendly, formaldehyde-free, and resistant to aging. The energy-absorbing layer 10 is made of carbon fiber reinforced polymer, which converts external impact energy (such as kinetic energy and vibration energy) into heat energy, elastic potential energy, or other forms of energy through physical deformation, structural damage, or energy dissipation, thereby reducing the damage to the target object. The flame-retardant layer 11 is made of decabromodiphenyl ether, which prevents or slows down the spread of flames, buying time for personnel evacuation, equipment protection, or fire extinguishing. The waterproof and moisture-proof layer 12 is made of EPDM rubber, which has high elasticity and weather resistance, can adapt to the deformation of the side panels caused by temperature changes, avoids cracking and leakage, and is resistant to chemical corrosion, making it suitable for outdoor or humid environments. The wear-resistant layer 13 is made of high-manganese steel and is used to resist mechanical actions such as friction, impact, and wear, protecting the base material. Through the arrangement of the low-density layer 8, high-density layer 9, energy-absorbing layer 10, flame-retardant layer 11, waterproof and moisture-proof layer 12, and wear-resistant layer 13, the sound insulation, impact resistance, flame retardancy, waterproofness, and wear resistance of the main body of the protective panel 1 are improved. In the event of an impact, the object first contacts the anti-collision strip 2, which effectively protects the main body of the protective panel 1, reducing the probability of damage. When the anti-collision strip 2 is damaged, the worker can pull it to remove the iron plate 6 from the placement slot 4, replace it with a new one, insert the iron plate 6 into the placement slot 4, and the iron plate 6 will adhere to the outer wall of the magnet 5, thus completing the replacement. This improves replacement efficiency and reduces usage costs.
