Referring to fig. 1 to 16, in an embodiment of the present invention, a louver-type sound-insulating window covering includes:

at least one louver 100, wherein the louver 100 includes a plurality of louvers 110 arranged in sequence and a plurality of connectors 120, the connectors 120 are disposed at two ends of the louver 110 in the length direction so as to connect two adjacent louvers 110, the connectors 120 are hinged to the louvers 110, the louver 100 includes at least three fasteners 300, the fasteners 300 are disposed at the upper and lower ends of the louver 100, respectively, and one end of the fastener 300 is connected to the louvers 110;

the fixed frame 200 comprises two vertical frames 220 and two transverse frames 210, the vertical frames 220 and the transverse frames 210 are connected with each other to form the fixed frame 200, the inner sides of the transverse frames 210 are provided with guide structures, and one ends of the fixing pieces 300 far away from the louvers 110 are matched with the guide structures in a sliding manner;

when the louver expansion assembly 100 is adjusted to be in the unfolded state, the louver expansion assembly 100 seals the fixing frame 200, and the adjacent louvers 110 are attached and sealed; when the louver assemblies 100 are adjusted to the folded state, the volume occupied by the louver assemblies 100 is reduced.

The plurality of louvers 110 are connected to each other by the connection member 120 to form a telescopic structure, and when the louver telescopic assembly 100 is adjusted to the unfolded state, the louver telescopic assembly 100 closes the fixing frame 200, thereby achieving a sound insulation effect. When the shutter assembly 100 is adjusted to the folded state, the volume occupied by the shutter assembly 100 is reduced, and the shutter type sound insulation curtain is no longer a barrier for communication between the indoor environment and the external environment. During the unfolding or folding process of the louver expansion assembly 100, the louver 110 rotates and translates, for example, the fixing member 300 is connected to the louver 110, so that the louver 110 rotates around the fixing member 300 and translates along the guiding structure together with the fixing member 300.

The connecting member 120 may be connected to the louver 110 by means of pins or screws, etc. The louver 110 can be a hollow aluminum profile, and can generate an interface of aluminum and air under the condition of light weight and material saving, so that the sound insulation effect is improved. In the extended louver expansion assembly 100, the adjacent louvers 110 can be fit and sealed in a shape complementary manner, and if the cross sections of the two ends of the louver 110 in the width direction respectively have a gently convex shape and a smoothly concave shape, the adjacent louvers 110 can be fit and sealed smoothly without hindering the rotation of the louver 110.

The fixing frame 200 is fixed to an external base structure (e.g., a wall). The louver telescopic assemblies 100 are installed in the fixing frame 200, the cross section of the fixing frame 200 can be L-shaped or U-shaped, and the like, but the fixing frame 200 needs to be sealed by the louver telescopic assemblies 100, so that the louver type sound insulation curtain can achieve a sound insulation effect. In this embodiment, the fixing frame 200 has a U-shape with a right angle in cross section, and the blind telescopic assembly 100 is installed in the fixing frame 200.

The louver 110 forms an integral telescopic structure by the connecting member 120, and the telescopic process or the integral sliding of the louver telescopic assembly 100 requires the direction restriction by the cooperation of the fixing member 300 and the guide structure. The more the number of the fixing members 300 is, the more stable the louver expansion assembly 100 is supported by, and the arrangement of at least three fixing members 300 respectively disposed at the upper and lower ends ensures that the louver expansion assembly 100 does not rotate integrally. In practice, each louver 110 or every several louvers 110 may be connected to the guiding structure at both ends in the length direction thereof by a fixing member 300, respectively, so as to support the louver telescopic assembly 100 by the fixing member 300.

In conclusion, the shutter type sound insulation curtain has a complete sound insulation state and a complete open state through the shutter telescopic assembly 100, the shutter telescopic assembly 100 is simple in structure, and the expansion and the folding are completed in the horizontal direction, so that the operation is convenient; after the shutter telescopic assembly 100 is adjusted to be in the unfolded state, the fixing frame 200 can be closed to form a sound insulation effect; when the shutter telescopic assembly 100 is adjusted to be a folded state, the indoor communication with the external environment is ensured to the maximum extent.

In one embodiment, the louver 110 includes at least one transparent material region extending through the thickness of the louver 110, and the transparent material region has an area of 5% to 95% of the louver 110.

The following use scenes exist for the window with the sound insulation effect: the sound insulation function is not started at all, and the air and light communication between the indoor space and the external environment is increased as much as possible; the sound insulation function is started, and the light communication between the indoor environment and the external environment is increased as much as possible; and the sound insulation function is started, so that the light communication between the indoor environment and the external environment is isolated.

In this embodiment, the requirement of "enabling a sound insulation function and simultaneously increasing light communication between the indoor space and the external environment as much as possible" can be met by the presence of the transparent material region. The requirement that the sound insulation function is not started at all and the air and light communication between the indoor and the external environment is increased as much as possible can be met by folding and retracting the louver telescopic assembly 100. If the sound insulation function is to be realized and the light communication between the indoor space and the external environment is to be isolated, other light shielding structures are required to be added to realize the function or to realize the function by adjusting the light transmission degree of the transparent material region (for example, by adopting a material with variable electro-transmissivity). Specifically, the shape of the transparent material region may be adjusted according to the appearance or the angle of processing, for example, the number of the transparent material regions is one and is located in the central region of the louver 110, or the number of the transparent material regions is plural and is spaced in the length direction of the louver 110. The transmittance parameter or the area occupation of the transparent material region can be selected according to the optical parameters of the application scene or the use habit of the user.

Referring to fig. 4-10, in one embodiment, the louver 110 includes first and second side bars 112 and 113, two end blocks 114, and a middle transparent plate 111; the two end blocks 114 are respectively arranged at two ends of the first side bar 112 and the second side bar 113 in the length direction to form a frame; the middle transparent plate 111 is disposed in the frame.

The structure of the louver 110 is set up such that the louver 110 can be processed with low difficulty to achieve the effect of having the transparent material region. Such as a screw connection between the first side bar 112 and the end block 114, and which screw may also simultaneously serve to secure the connecting member 120. The middle transparent plate 111 may be a glass plate, a plexiglas plate, a tempered glass panel, or a double-layer glass plate, etc.

Referring to fig. 2-3, in one embodiment, every other louver 110 is coupled to the guide structure at both ends in the lengthwise direction thereof by one of the fixing members 300, respectively.

The louver 110 forms a telescopic structure through the connecting member 120, and the telescopic process or the overall sliding process of the louver telescopic assembly 100 requires directional limitation through the cooperation of the fixing member 300 and the guide structure. The fixing members 300 are connected to both ends of each louver 110 in the length direction, so that the entire louver telescopic assembly 100 is supported more stably, and the structural strength of the louver type sound insulation curtain can be improved. However, in the verification process, it is found that there is no need to connect the fixing member 300 to each louver 110, and by spacing one louver 110 and connecting one fixing member 300 to each end in the length direction, the louver telescopic assembly 100 can be stably supported, and the material can be saved, and the friction force formed between all the fixing members 300 and the guide structure can be reduced by reducing the number of the fixing members 300.

In one embodiment, the guide structure is a guide groove 211, the fixing member 300 includes a fixing shaft 310 and a roller 320, one end of the fixing shaft 310 is connected to the louver 110, and the roller 320 is rotatably connected to the fixing shaft 310.

Sliding friction is converted into rolling friction through the roller 320, so that resistance to the telescopic process or the whole sliding process of the louver telescopic assembly 100 is reduced, the difficulty of operation of a user is reduced, and the probability of abrasion or deformation of the fixing member 300 can be reduced to a certain extent.

In one embodiment, the guide slot 211 is a gap 115 with a height of 0.05 to 0.15mm between the top end of the shutter 110 in the longitudinal direction and the shutter 110, and the shutter telescopic assembly 100 in the unfolded state covers the opening of the guide slot 211.

The fixed shaft 310 is coupled to the roller 320 in the guide groove 211 through the opening. The presence of the gap 115 between the guide slot 211 and the shutter 110 first facilitates the unfolding and folding process of the shutter telescopic assembly 100; meanwhile, the effect of reducing noise can be achieved. Specifically, when noise passes through the gap 115, a slit noise elimination effect is generated due to the narrow size of the gap 115; when noise passes through the gap 115 in the thickness direction of the shutter-type sound insulation curtain, the noise experiences the size change of the sound transmission channel, and a double-resistance noise elimination effect is generated; while noise, when passing through the gap 115, also enters the guide groove 211 from the gap 115, also undergoes a change in the size of the sound transmission channel, producing a second reactive noise cancellation effect. The height of the gap 115 is too small to facilitate the process control, while too large to facilitate the sound insulation effect, preferably 0.05 to 0.15 mm.

Referring to fig. 10, in one embodiment, the longitudinal end surface of the louver 110 has a concave structure corresponding to the position of the connecting member 120, and the connecting member 120 is installed to sink in the concave structure.

Through the concave structure of the louver 110, the outer surface of the connecting piece 120 does not exceed the end surface of the louver 110 in the length direction, so the size of the gap 115 between the louver 110 and the guide groove 211 is easy to ensure, and the louver telescopic component 100 is favorable for the state change and the sound insulation effect.

Referring to fig. 4-5, in one embodiment, the fixing frame 200 has a shield 240 on a side thereof mating with the blind telescopic assembly 100, the shield 240 for covering the blind telescopic assembly 100 in an at least partially folded state.

The shutter 110 is rotated, when the shield 240 does not exist, the shutter telescopic assembly 100 in the folded state is exposed out of the overall appearance of the shutter-type sound insulation curtain, which is not good for safe use and appearance effect, and at this time, the shield 240 can overcome the above problems; of course, the shield 240 is in a functionally idle state when the blind retraction assembly 100 is in the extended state.

In one embodiment, at least one sealing bead 230 is provided on the outer side of the fixing frame 200 matching with the external infrastructure, the sealing bead 230 being provided along the circumference of the fixing frame 200 as a whole; wherein the sealing bead 230 is raised above the outer surface of the fixing frame 200.

When the number of the sealing beads 230 is plural, the plural sealing beads 230 are formed in a nested relationship with each other, thereby forming a multiple sealing with an external base structure (the external base structure may be a wall, etc.). The sealing bead 230 may be a unitary or split structure. In this embodiment, two sealing strip rings 230 are formed by a plurality of rubber sealing strips, and the specific fixing frame 200 is provided with an inner shallow groove and an outer shallow groove for installing the rubber sealing strips, wherein when the rubber sealing strips are installed on the shallow grooves, the rubber sealing strips are higher than the outer surface of the fixing frame 200 by 1 to 3 mm.

In one embodiment, the inner side of the mullion 220 and/or the transom 210, which is matched with the plane of the telescopic louver assembly 100 in the unfolded state, is provided with at least one protruding structure;

the extending direction of the protruding structure on the vertical frame 220 corresponds to the length direction of the vertical frame 220, and the extending direction of the protruding structure on the horizontal frame 210 corresponds to the length direction of the horizontal frame 210;

the distance between the free end of the protruding structure and the shutter telescopic assembly 100 in the unfolded state is selected from 0.04 to 0.20mm, and the height of the protruding structure protruding from the inner side surface of the fixing frame 200 is 0.50 to 2.00 mm.

The extending direction of the protruding structure is not necessarily a straight line, and when the protruding structure is disposed on the mullion 220, the extending direction of the protruding structure corresponds to the length direction of the mullion 220; when the protruding structure is disposed on the horizontal frame 210, the extending direction of the protruding structure corresponds to the length direction of the horizontal frame 210. Meanwhile, when the plurality of protruding structures exist, the mutual connection is not limited to be arranged in parallel.

The free end of the protruding structure means the free end of the protruding structure close to the shutter telescopic assembly 100, and the distance between the free end of the protruding structure and the shutter telescopic assembly 100 in the unfolded state is selected to be 0.04-0.20 mm, so that a slit is formed, and a slit silencing effect is formed. At the position of the area where the protruding structure is located, a cavity connected to the slit is formed between the fixed frame 200 and the louver array of the louver telescopic assembly 100 in the unfolded state (the depth of the cavity is determined by the size of the protruding structure protruding from the fixed frame 200), and a reactive noise elimination effect is formed between the cavity and the slit. The slit muffling effect has an excellent muffling effect for high-frequency noise, and the reactive muffling effect has an excellent muffling effect for low-frequency noise. The thickness of the slit is too large, so that the noise elimination effect is poor, and the thickness of the slit is too small, so that the slit is difficult to be accurately processed. When the number of the protruding structures is multiple, the effect that the resistive mufflers and the reactive mufflers are connected in series is formed, and the full-frequency muffling effect is greatly improved.

In one embodiment, the number of the louver assemblies 100 is two, and when the two louver assemblies 100 in the unfolded state are spliced, a seal is formed between the louvers 110 in contact between the two louver assemblies 100.

The arrangement of the two shutter assemblies 100 accords with the operation habit of a common user.

2-3, in one embodiment, the two louvers 110 of the two louver assemblies 100 at the end away from the mullion 220 are provided with corresponding pairs of magnetic members 400; the louver assemblies 100 in the adjacent unfolded state are closed by attraction between the pair of magnetic members 400.

After the shutter telescopic assemblies 100 are unfolded, the shutter telescopic assemblies have the tendency of being loosened towards the contraction state, and the sealing and sound insulation effects between the adjacent shutters 110 when the single shutter telescopic assembly 100 is in the unfolding state are influenced; but also the ground sealing and sound insulating effect of the two louver assemblies 100. In the embodiment, the pair of magnetic members 400 includes a first magnet and a second magnet, the first magnet and the second magnet are respectively disposed on the louvers 110 at the end of the two louver expansion assemblies 100 far from the mullion 220, when the two louver expansion assemblies 100 are both in the extended state, the first magnet and the second magnet attract each other, so that the tendency of the louver expansion assemblies 100 to be loose toward the retracted state is suppressed. The magnetic member pair 400 is preferably disposed at a position invisible, for example, at a region where the louver 110 is shielded by the fixing frame 200.

In one embodiment, the fixing frame 200 is provided with a stopper, and the stopper limits the sliding of the louver 110 of the louver telescopic assembly 100 near one end of the fixing frame 200 along the guiding structure.

When the sliding of the blind telescopic assembly 100 on the guiding structure is not limited, the operation of the blind telescopic assembly 100 is more flexible, for example, the blind telescopic assembly 100 in the folded state can be accommodated in any position of the guiding structure. In the present embodiment, the sliding of the entire louver telescopic assembly 100 on the guiding structure is not limited, so that the abnormal displacement of the louver telescopic assembly 100 when the user operates the louver telescopic assembly is reduced. The limiting piece can be a pin or a protruding block.

In summary, the louver-type sound insulation curtain provided by the utility model has the advantages that the louver-type sound insulation curtain has the complete sound insulation state and the complete open state through the louver telescopic component 100, the louver telescopic component 100 is simple in structure, and the expansion and the folding are completed in the horizontal direction, so that the operation is convenient; after the shutter telescopic assembly 100 is adjusted to be in the unfolded state, the fixing frame 200 can be closed to form a sound insulation effect; when the shutter telescopic assembly 100 is adjusted to be a folded state, the indoor communication with the external environment is ensured to the maximum extent.
