[0036] Combination Figure 4-5 A protective component is arranged on the outside of the sound-absorbing panel 10, and the protective component includes an anti-collision panel 5, which is arranged inside the door leaf 1, and the anti-collision panel 5 is arranged on the outside of the sound-absorbing panel 10, and the anti-collision panel 5 includes two fire door cores 9, and the two fire door cores 9 are distributed on both sides of the sound-absorbing panel 10. The material of the two fire door cores 9 is magnesium chloride. The entire anti-collision panel 5 is fixedly installed on the inside of the door leaf 1 through the fixing block 4, so that the door leaf 1 can withstand a certain degree of impact.

[0038] Working principle: Since the entire anti-collision plate 5 is fixedly installed inside the door leaf 1 through the fixing block 4, the door leaf 1 can withstand a certain degree of impact. Since the anti-collision plate 5 is composed of two fire door cores 9, which are respectively attached to the two sides of the door leaf 1, the protection is more comprehensive. The material of the fire door core 9 is magnesium chloride with extremely high protectiveness, so it can well protect against impact and play a shockproof function. A sound-absorbing plate 10 is arranged between the two fire door cores 9 to make up for the shortcomings of the fire door core 9 with poor sound absorption effect. Since the sound-absorbing plate 10 is respectively composed of a sound-absorbing plate core 1 11, a sound-absorbing plate core 2 12 and a sound-absorbing plate core 3 13 connected together, the sound-absorbing plate 10 can withstand a certain degree of impact. The materials of the sound board core 11, the sound absorbing board core 2 12 and the sound absorbing board core 3 13 are composed of rock wool with good sound absorption, so a certain sound absorption effect can be achieved. At the same time, the sound absorbing board core 11 and the sound absorbing board core 3 13 outside the sound absorbing board core 2 12 are respectively provided with evenly distributed sound absorbing board cores 11 and 13, and the arrangement of the sound absorbing board core 1 11 and the sound absorbing board core 3 13 does not correspond to each other, so that the sound absorbing board core 2 12 located between the sound absorbing board core 1 11 and the sound absorbing board core 3 13 can absorb part of the sound through the hole 14 and the hole 2 15, so that the three sound absorbing board cores can achieve a higher sound absorption function.
