All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0040] Please refer to Figure 1-8 , the present invention provides a technical solution: a sound insulation space design structure for a hidden room within a room in a door opening, including: a shock-absorbing and sound-insulating floor 1, a shock-absorbing and sound-insulating wall 2, a shock-absorbing and sound-insulating ceiling 3, and a composite door body 4. There is an original door opening on the basic wall 5. The shock-absorbing and sound-insulating wall 2 includes an acoustic shock absorber 22, a horizontal keel 23, a vertical keel 24, and a wall panel 25. The acoustic shock absorber 22 is fixedly installed on the horizontal keel 23. One end of the acoustic shock absorber 22 is fixedly installed on the basic wall 5 through a screw. The vertical keel 24 is fixedly installed on the horizontal keel 23. The wall panel 25 is fixedly installed on the vertical keel 24. An inner door opening 21 corresponding to the original door opening is provided on the wall panel 25. The composite door body 4 includes an outer door body 41 and an inner door body 42. The outer door body 41 is arranged on the front side of the inner door opening 21. The outer door body 41 contacts the wall panel 25. One end of the outer door body 41 is connected to a driving device 6. The driving device 6 is fixedly installed on the ground through a bracket. The driving device 6 is used for the telescopic driving rod of the outer door body 41 to pass through the vertical keel 24, and the diameter of the through hole of the vertical keel 24 for avoiding the telescopic driving rod is larger than the diameter of the telescopic driving rod, so as to prevent the wall panel 25 from vibrating and causing the telescopic driving rod to collide and damage with the vertical keel 24. The driving device 6 is used to drive the outer door body 41 to slide horizontally. A sliding groove 411 is provided on the outer door body 41. One end of the sliding groove 411 extends to the end face of the outer door body 41. The inner door body 42 is arranged within the inner door opening 21. A connecting member 421 is provided on the back of the inner door body 42. The connecting member 421 is slidably connected in the sliding groove 411. The inner door body 42 is slidably connected to the outer door body 41 through the connecting member 421. The width of the outer door body 41 is larger than the width of the inner door body 42.

[0041] The end face of the outer door body 41 is an arc surface, which is convenient for rotating and opening the inner door body 42.

[0042] The connecting member 421 includes a connecting head 4211 and a seat body 4212. The seat body 4212 is fixedly installed on the back surface of the inner door body 42. The connecting head 4211 is elastically connected to the seat body 4212. The connecting member 421 is integrally in a "T" shape. When the connecting member 421 is connected to the outer door body 41, first place the connecting head 4211 horizontally into the sliding groove 411, and then rotate it 90 degrees so that the connecting head 4211 is in a vertical state to prevent the connecting member 421 from disengaging from the outer door body 41 backward. Finally, fix the connecting member 421 to the inner door body 42. The elastic connection between the connecting head 4211 and the seat body 4212 can effectively cope with the change in the distance between the surface of the inner door body 42 and the outer door body 41 when the inner door body 42 rotates and opens, ensure that the inner door body 42 fits the outer door body 41, and at the same time avoid the connecting head 4211 from being stretched and deformed, thereby effectively ensuring the stability of the connection structure and the airtight effect of the composite door body 4.

[0043] A plurality of parallel sliding grooves 411 are provided on the outer door body 41. A plurality of connecting members 421 corresponding to the sliding grooves 411 in position are provided on the back surface of the inner door body 42. One connecting member 421 corresponds to one sliding groove 411, which improves the smoothness of the sliding of the inner door body 42 and the connection effect.

[0044] The wall panel 25 is a composite sound insulation wall panel. The wall panel 25 includes a metal base plate 251, a honeycomb core plate 252, a corrugated plate 253, and a gypsum panel 254. A circumferentially arranged edge 2511 is provided on the metal base plate 251. The edge 2511 encloses an accommodation space. The honeycomb core plate 252 is fixedly installed on the metal base plate 251. The honeycomb core plate 252 is arranged in the accommodation space. The corrugated plate 253 is arranged in the accommodation space. A polyester fiber board is provided between the corrugated plate 253 and the honeycomb core plate 252. The polyester fiber board is fixedly installed on the honeycomb core plate 252. The corrugated plate 253 is fixedly installed on the polyester fiber board. The gypsum panel 254 is fixedly installed on the corrugated plate 253. The layers of the wall panel 25 can be specifically fixed by bonding. The corrugated plate 253 in the wall panel 25 can absorb sound wave vibration through deformation and perform vibration damping, weakening the transmission of sound waves. At the same time, the holes of the honeycomb core plate 252 are used to block the transmission of sound, which can effectively achieve the shock absorption and sound insulation of the wall of the inner sound insulation space of the "room within a room".

[0045] The driving device 6 is an electric push rod, which is convenient for smoothly pushing the outer door body 41.

[0046] The thickness of the inner door body 42 is equal to the thickness of the wall panel 25, which fully seals and hides the inner door opening 21.

[0047] The shock absorption and sound insulation floor 1 includes a rubber vibration isolation and sound insulation pad 11 and a floor board 12. The rubber vibration isolation and sound insulation pad 11 is fixedly installed on the base floor, and the floor board 12 is fixedly installed on the rubber vibration isolation and sound insulation pad 11, realizing the shock absorption and sound insulation of the floor of the inner sound insulation space of the "room within a room".

[0048] The shock-absorbing and sound-insulating top surface 3 includes a suspended ceiling board 31, a keel frame 32, and shock absorbers 33. The shock absorbers 33 are fixedly installed on the building top surface, the keel frame 32 is fixedly installed at the bottom of the shock absorbers 33, sound insulation cotton is laid on the keel frame 32, and the suspended ceiling board 31 is fixedly installed at the bottom of the keel frame 32. The suspended ceiling board 31 includes calcium silicate board, sound insulation felt, and gypsum board. The calcium silicate board is fixedly installed at the bottom of the keel frame 32, the sound insulation felt is bonded to the back of the gypsum board, and the gypsum board is fixedly installed on the keel frame 32 through screws. The screws pass through the calcium silicate board to achieve the shock absorption and sound insulation of the top surface of the inner sound insulation space of the "room within a room".

[0049] Working principle: By using the gap between the wall panel 25 and the base wall, a double-opening composite door body 4 is set up to effectively achieve the closure and concealment of the inner door opening 21. The composite door body 4 blocks the inner door opening 21 through the inner door body 42, and the width of the outer door body 41 is greater than that of the inner door body 42, which can effectively block the gap between the inner door body 42 and the inner door opening 21, and the double-layer closure can effectively improve the sound insulation effect. On the one hand, the composite door body 4 can effectively achieve the flatness of the inner wall surface of the room within a room and effectively conceal the door opening on the inner wall surface of the inner sound insulation room. On the other hand, it can effectively improve the sound insulation effect at the inner door opening 21, prevent the gap from becoming larger after being opened many times like an ordinary flat door, and ensure the sound insulation effect.

[0050] When the composite door body 4 is opened, the outer door body 41 is pulled by the electric push rod and retracts between the shock-absorbing and sound-insulating wall 2 and the original wall to achieve the initial opening of the composite door body 4. After that, when the outer door body 41 moves to the limit position, the inner door body 42 is manually pushed, and the inner door body 42 rotates along the end of the outer door body 41 through the connecting piece 421 to achieve the full opening of the composite door body 4.
