Description

Technical Field

[0001] The invention relates to the technical field of sound insulation wall panels, in particular to a composite wall panel with adjustable noise reduction effect. Background Art

[0002] Compound wall panels are designed to solve noise problems in different environments and can adjust their noise reduction performance according to actual needs. Compound wall panels usually adopt a multi-layer structure to achieve different noise reduction effects. These layers may include: an outer sound-absorbing layer, which usually uses materials with high sound absorption performance, such as mineral wool, glass wool or foam plastic, to absorb noise waves, a middle sound insulation layer, which is composed of sound insulation materials or airtight materials with high acoustic impedance to prevent noise penetration, and an inner layer structure with a certain hardness of the material, which further improves the sound insulation effect of the wall and may support the isolation of noise of different frequencies. At present, the application scenarios of compound wall panels are very wide, but the requirements for noise reduction effects are different in different usage scenarios, so compound wall panels of different specifications and models are not compatible.

[0035] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0036] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0037] Example 1

[0038] Reference Figure 1 to Figure 8 , which is the first embodiment of the present invention, provides a duplex wall panel with adjustable noise reduction effect, including a sound insulation layer 100, a connecting mechanism, a noise reduction mechanism and an adjusting mechanism. The noise is reduced by circulating the gas in the reserved pipe 201, and each air chamber 300 is synchronously expanded and contracted to adapt to different noise reduction demand environments.

[0039] Specifically, it includes a sound insulation layer 100, the sound insulation layer 100 is provided with at least three layers, each sound insulation layer 100 is connected in parallel and sound absorbing materials are filled between each sound insulation layer 100, and the outermost sound insulation layer 100 is fixedly arranged;

[0040] The connection mechanism includes a positioning column 200 and a reserved tube 201. The positioning column 200 is used to be fixedly connected to the outermost sound insulation layer 100, and the remaining sound insulation layers 100 are slidably sleeved along the positioning column 200;

[0041] The noise reduction mechanism includes a flow guide component disposed in the sound insulation layer 100, the flow guide component is used to circulate the gas after entering the reserved pipe 201, and the flow guide component includes an air chamber 300 disposed in the reserved pipe 201, and each air chamber 300 synchronously expands and contracts to drive each sound insulation layer 100 to move and generate volume changes, thereby eliminating high-frequency noise and low-frequency noise respectively;

[0042] The adjustment mechanism includes a sound insulation plate 400 slidably arranged in the reserved pipe 201 . A pipeline 401 is arranged in the reserved pipe 201 . The sound insulation plate 400 is closely attached to the outer wall of the pipeline 401 .

[0043] Among them, in this embodiment, there are four sound insulation layers 100, the outermost sound insulation layer 100 is fixedly set on the ground, the positioning column 200 is fixedly connected to the outermost sound insulation layer 100, and the remaining three sound insulation layers 100 are slidably sleeved on the outer wall of the positioning column 200.

[0044] Preferably, the sound insulation layers 100 in this embodiment are respectively a first sound insulation layer 1001, a second sound insulation layer 1002, a third sound insulation layer 1003 and a fourth sound insulation layer 1004 from right to left, an air intake pipe 1005 is provided on the inner wall of the first sound insulation layer 1001, and relay pipes 1006 are slidably provided in the second sound insulation layer 1002 and the third sound insulation layer 1003.

[0045] Among them, the outer wall sliding sleeve of the reserved tube 201 is provided with a second sound insulation layer 1002, a third sound insulation layer 1003 and a fourth sound insulation layer 1004, one end of the air intake pipe 1005 is fixedly connected to the inner wall of the first sound insulation layer 1001, and the reserved tube 201 and the relay tube 1006 are also fixedly connected to the positioning column 200 to ensure that the position remains unchanged.

[0046] More preferably, the air intake pipe 1005 and the relay pipe 1006 are symmetrically arranged on both sides of the reserved pipe 201. After the external gas enters the air intake pipe 1005 from outside the first sound insulation layer 1001, it enters each air chamber 300 for noise reduction, thereby increasing the gas flow range and improving the noise reduction effect.

[0047] Furthermore, a shell 1007 is provided below the reserved pipe 201 , a moving block 1008 is slidably provided inside the shell 1007 , and a flip shaft 1009 is provided on the outer wall of the sound insulation plate 400 , and the flip shaft 1009 controls the angle flipping of the sound insulation plate 400 .

[0048] Among them, in this embodiment, when the reserved tube 201 is not installed in the pipeline 401, it plays the role of a gas flow channel. The reserved tube 201 is circular, the sound insulation disk 400 is a disk, and the axis of the flip shaft 1009 coincides with the center of the sound insulation disk 400. Therefore, the opening of the reserved tube 201 can be adjusted by rotating the sound insulation disk 400, thereby controlling the gas flow and flow rate, thereby further adjusting the noise reduction effect and ventilation effect.

[0049] More preferably, two folding arms 1011 are symmetrically provided on the outer wall of the flip shaft 1009, the moving block 1008 located at one end of the reserved tube 201 is fixedly connected, and the other moving blocks 1008 are slidably arranged, and the folding arms 1011 on each moving block 1008 are rotatably connected to each other.

[0050] Among them, the two folding arms 1011 are arranged in an X shape, and the folding arms 1011 rotate with the moving block 1008 as the center of the circle, so that the moving block 1008 is driven to slide along the shell 1007 during the expansion or contraction of the folding arms 1011, so that each sound insulation disk 400 moves synchronously, and the second sound insulation layer 1002, the third sound insulation layer 1003 and the fourth sound insulation layer 1004 adjacent to the sound insulation disk 400 move synchronously with the sound insulation disk 400.

[0051] Among them, when each air chamber 300 increases in proportion, the capacity of the air layer increases and the isolation effect of low-frequency noise is enhanced; conversely, when the air chamber 300 decreases in proportion, the cavity thickness decreases, which meets the sound insulation requirements of high-frequency noise.

[0052] Example 2

[0053] Reference Figure 1 to Figure 8, which is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but the difference is that after the sound insulation disc 400 and the sound insulation layer 100 are extended and retracted, the shell 1007 is extended as a mounting pile, and the power supply line is installed through the reserved pipe 201, which is simple and convenient, and avoids the decrease in noise reduction effect caused by decoration drilling. It can fit and seal lines of various diameters and sizes, and always maintain the noise reduction effect.

[0054] Specifically, an eccentric arm 2001 is provided at one end extending from the flip shaft 1009 below the moving block 1008 , and a synchronization frame 2011 is sleeved on the outer wall of the eccentric arm 2001 . The eccentric arms 2001 on each moving block 1008 are slidably sleeved in the synchronization frame 2011 , and the synchronization frame 2011 is parallel to the shell 1007 .

[0055] A driving disk 2002 is rotatably provided inside the sound insulation disk 400 , a movable groove 2003 is provided in a circular array on the driving disk 2002 , a guide groove 2004 is provided on the inner wall of the sound insulation disk 400 , and a blade 2005 is movably provided between the inner wall of the sound insulation disk 400 and the driving disk 2002 .

[0056] Among them, a cylinder 2006 is vertically fixed at one end of the blade 2005, and both end surfaces of the cylinder 2006 are slidably arranged in the moving groove 2003 and the guide groove 2004 at the same time, and each blade 2005 is embedded with each other.

[0057] Better, such as Figure 6 , each blade 2005 is interlocked to form a ring. When the blade 2005 shrinks to the minimum, they are spliced ​​together to form a complete pattern and close the sound insulation plate 400. The guide groove 2004 is a straight groove, the moving groove 2003 is an arc groove, and there is an angle between the guide groove 2004 and the moving groove 2003.

[0058] Furthermore, the driving disk 2002 can rotate inside the sound insulation disk 400, thereby driving the cylinder 2006 and the blade 2005 to move through the movable groove 2003. The movable groove 2003 drives the cylinder 2006 to slide. At the same time, the cylinder 2006 is also limited by the guide groove 2004 and can only slide in the guide groove 2004. Therefore, the position of the cylinder 2006 is always the overlapping position of the guide groove 2004 and the movable groove 2003.

[0059] When the driving disk 2002 rotates counterclockwise, the overlapping position of the guide groove 2004 and the movable groove 2003 moves outward, driving the cylinder 2006 to move outward, and the blades 2005 fit each other and slide outward, forming a cavity in the middle.

[0060] More preferably, a hollow cylinder 2007 is provided on the end face of the folding arm 1011 , and the hollow cylinder 2007 is movably sleeved on the outer wall of the flip shaft 1009 , and the hollow cylinder 2007 rotates to penetrate into the sound insulation disk 400 and fits with the end face of the driving disk 2002 , and a tooth pattern 2008 is provided on the outer wall of the hollow cylinder 2007 .

[0061] Among them, in this embodiment, when the hollow tube 2007 rotates, it fits the driving disk 2002 through the tooth pattern 2008 and drives the driving disk 2002 to rotate, and finally realizes the extension and expansion of the blade 2005. At the same time, the flip shaft 1009 extends out of one end of the hollow tube 2007 and is directly fixedly connected to the sound insulation disk 400, so that the flip shaft 1009 directly controls the angle rotation of the sound insulation disk 400.

[0062] In summary, when in use, by controlling the movement of the synchronization frame 2011, the eccentric arms 2001 are driven to swing synchronously, the rotation of the flip shaft 1009 is realized, and finally the opening of the sound insulation disk 400 is adjusted to adjust the balance between the air intake volume and the noise reduction effect. At the same time, the folding arm 1011 is rotated so that the connected folding arms 1011 are folded or unfolded synchronously, and the sound insulation disks 400 are close to or away from each other, so as to adjust the size of the internal space of the air chamber 300. After the sound insulation disk 400 and the sound insulation layer 100 are contracted, the exposed shell 1007 is stretched out and used as an installation pile when decorating indoor TVs or monitoring equipment, and the power supply and signal transmission lines are directly installed through the pipeline 401 on the reserved pipe 201, which is simple and convenient, and avoids the reduction of noise reduction effect caused by drilling holes for decoration.

[0063] At the same time, when the folding arm 1011 swings and causes the sound insulation disks 400 to approach each other, the folding arm 1011 will also drive the hollow tube 2007 to rotate and fit the drive disk 2002 through the tooth pattern 2008 and drive the drive disk 2002 to rotate, thereby realizing the extension and retraction of the blades 2005. At this time, the power supply and signal transmission lines can be passed through, and then the folding arm 1011 swings in the opposite direction to reset, automatically driving each blade 2005 to move closer to the middle and fit with the power supply and signal transmission lines, so that lines of various diameters can be fitted and sealed, and the noise reduction effect can be automatically adjusted to the best.

[0064] For example, in other embodiments, the farthest folding arm 1011 is independently controlled and remotely controlled by a motor. At this time, after the power supply and signal transmission lines are fixed to the outermost sound insulation disk 400, the blades 2005 at that location are directly contracted and clamped individually, and then the blades 2005 can be driven to move outward, thereby realizing automatic laying of cables and improving installation efficiency.

[0065] Example 3

[0066] Reference Figure 1-Figure 8, which is the third embodiment of the present invention. This embodiment is based on the previous embodiment, but the difference is that the extension and expansion of each sound insulation disk 400 is achieved by rotating the transmission wheel 3003 in the forward and reverse directions, thereby realizing remote control, which is convenient and fast.

[0067] Specifically, a cavity 3001 is provided inside the moving block 1008 , and a power ring 3002 is rotatably provided on the outer wall of one end of the flip shaft 1009 located in the cavity 3001 , and a transmission wheel 3003 is provided on the lower end surface of the power ring 3002 .

[0068] Among them, a first ratchet 3004 is provided on the inner wall of one end of the hollow cylinder 2007 that rotates and penetrates into the cavity 3001 , a first ratchet 3005 is rotatably provided on the power ring 3002 , and a second ratchet 3006 is also provided inside the power ring 3002 .

[0069] Among them, the first pawl 3005 is always attached to the first ratchet 3004 under the action of the elastic member, the power ring 3002 is coaxially arranged with the flip shaft 1009 and the hollow cylinder 2007, and the first ratchet 3004 and the second ratchet 3006 are arranged in the same direction.

[0070] Furthermore, a second pawl 3007 is rotatably provided on the outer wall of the flip shaft 1009 , and the second pawl 3007 is always in contact with the second ratchet tooth 3006 .

[0071] When the transmission wheel 3003 rotates clockwise, the hollow cylinder 2007 is driven to rotate through the first ratchet 3005 on the power ring 3002. At this time, the second ratchet 3007 and the second ratchet 3006 are idle. When the transmission wheel 3003 rotates counterclockwise, the flip shaft 1009 is driven to rotate through the second ratchet 3006 on the power ring 3002.

[0072] Among them, in this embodiment, the transmission wheel 3003 realizes the flipping of the sound insulation disk 400 and the extension and expansion of each sound insulation disk 400 when rotating forward and backward. The transmission wheel 3003 is driven by a servo motor and can be remotely controlled to realize the overall movement of the composite wall and the adjustment of the ventilation effect and noise reduction effect, which is simple and convenient.
