DETAILED DESCRIPTION

[0029] Clearly, the described embodiments are merely a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0030] Please refer to Figs. 1 to 3 The wood-plastic door of the present application has two structural parts, the door frame 1 is used for connecting the door pocket for opening and closing, and the door panel 2 is used as the main door structure for sound insulation and noise reduction.

[0031] It should be noted that the rectangular periphery of the door frame 1 is integrally formed with an L-shaped edge 101 towards the door panel 2, and the edge 101 surrounds a rectangular space for the door panel 2 to be attached to the door frame 1.

[0032] It should be noted that the length and width of the edge 101 are greater than the length and width of the door panel 2, so that a rectangular gap 102 is reserved between the edge 101 and the door panel 2, and the door frame 1 and the door panel 2 are connected with a fillet 3 for reducing the hard contact between the door panel 2 and the door frame 1, thereby reducing the vibration of sound wave conduction, wherein the fillet 3 is embedded in the gap 102 to fill the space between the door panel 2 and the edge 101.

[0033] In the present application, the surface of the door panel 2 is fixedly installed with a rubber pad 4, one end of the rubber pad 4 is fixed on the door panel 2, and the rubber pad 4 can cover the gap 102 due to its elasticity, so that the fillet 3 in the gap 102 is hidden, thereby improving the appearance of the wood-plastic door.

[0034] Further, the door panel 2 is selected to be a cover plate with a U-shaped cross section, and the inner surface of the cover plate is covered with thermal insulation cotton for improving the overall thermal insulation capacity of the door panel 2, and a sound insulation structure is arranged between the inner cavity of the door panel 2 and the inner wall of the door frame 1,

[0035] The sound insulation structure includes a rubber shock-absorbing block 5 fixedly connected to the door frame 1, sound insulation cotton 6, and a sound insulation layer structure, the rubber shock-absorbing block 5 is arranged in an array on the inner wall of the door frame 1, and the sound insulation cotton 6 is arranged in a rectangular block shape longitudinally between adjacent rubber shock-absorbing blocks 5.

[0036] In this way, the door panel 2 structure can be installed by using the rubber shock-absorbing block 5 as the main contact support point, so that the door panel 2 can vibrate between the gap 102 to weaken the sound wave energy, and the sound insulation cotton 6 is longitudinally filled to improve the coverage rate of the sound insulation structure.

[0037] Meanwhile, since the rubber shock-absorbing blocks 5 are arranged in an array, in the transverse direction, several air cavities can be formed between adjacent rubber shock-absorbing blocks 5, and the air layer is used to form the floating casting structure of the door panel 2 and to isolate the sound propagation.

[0038] It is to be further explained that the rubber shock-absorbing blocks 5 are specifically in the form of 50mm-thick cubic structures, and the thickness of the sound insulation cotton 6 is selected to correspond to the size of the rubber shock-absorbing blocks 5.

[0039] In the embodiment, the sound insulation layer structure includes a first calcium silicate plate 7 covering the surface of the rubber shock-absorbing blocks 5 and the sound insulation cotton 6, a sound insulation felt 8 covering the surface of the first calcium silicate plate 7, and a second calcium silicate plate 9 covering the surface of the sound insulation felt 8.

[0040] It is to be further explained that the first calcium silicate plate 7 and the second calcium silicate plate 9 are both selected to be 5mm-thick rectangular structure plates, and the sound insulation felt 8 is 3mm-thick damping sound insulation felt, which has a significant effect on the isolation of daily middle-frequency noise.

[0041] In order to reduce the vibration transmission of the door frame 1 caused by the vibration of the door panel 2, the surface of the fillet 3 is recessed towards the inside of the fillet 3, and the recessed cavity 301 is inserted with sound-absorbing cotton strips 302, which are continuously and spaced apart in the recessed cavity 301.

[0042] In this way, the recessed cavity 301 can form an air cavity to block the propagation of sound.

[0043] Further, first and second ratchet belts 303 and 304 are arranged between adjacent sound-absorbing cotton strips 302, and the first and second ratchet belts 303 and 304 are both in the form of belt structures with continuous protrusions on the surface, and the protrusions of the first and second ratchet belts 303 and 304 are opposite to each other and are staggered.

[0044] The first and second ratchet belts 303 and 304 are distributed in the cavity of the fillet 3, so that the sound waves conducted in the air layer need to pass through the bending gap between the first and second ratchet belts 303 and 304, thereby achieving the sound absorption effect.

[0045] The working principle of the above embodiment is that when the noise sound wave is conducted to the wood-plastic door, the door panel 2 as the main structure of the wood-plastic door is in substantial contact with the sound wave energy, and the sound wave energy is transmitted along the door panel 2, wherein the first calcium silicate plate 7, the sound insulation felt 8 and the second calcium silicate plate 9 in the multi-layer structure of the door panel 2 form a main sound insulation structure to block the direct sound of the sound wave, and at the same time, due to the floating cast connection between the first calcium silicate plate 7 and the door frame 1 through the rubber shock-absorbing block 5 and the sound insulation cotton 6, the reflected sound can be reduced and continue to be transmitted along the sound insulation layer structure, after receiving the sound wave energy, the door panel 2 can produce a slight vibration relative to the door frame 1, at this time, the direct hard contact between the door panel 2 and the door frame 1 is prevented by the fillet 3, the energy carried by the sound wave in the transmission is weakened by the air cavity in the fillet 3 and the bending gap surrounded by the first ratchet belt 303 and the second ratchet belt 304 in the air cavity, so as to eliminate the reflected sound and realize the effective isolation of the noise.

[0046] The electrical components appearing in the text are all electrically connected with the main controller and the power supply. The main controller can be a conventional known device such as a computer for control, and the existing disclosed power connection technology is not described herein.
