Description

A silent cabin Technical Field

[0001] This application relates to the field of noise reduction or soundproofing equipment technology, specifically to a noise reduction cabin. Background Technology

[0002] Soundproof cabins, also known as soundproof office cabins, independent houses, private cabins, small meeting cabins, live streaming cabins, etc., are placed in office areas or public places. They have excellent sound insulation performance, allowing 1-4 people to gather together for meetings, conversations, emotional expression, video calls, and live streaming without being disturbed by the external environment. The structure of a typical soundproof cabin includes a square, enclosed compartment comprising wall panel assemblies, a top assembly, and a bottom assembly. To facilitate packaging and transportation, the soundproof cabin is prefabricated at the factory into multiple functional modules, such as multiple wall panel assemblies, top assemblies, bottom assemblies, and door panels. However, during on-site assembly, each functional module must be pieced together, especially for larger soundproof cabins which have more modules, making assembly more time-consuming and labor-intensive.

[0003] To facilitate packaging and transportation, and to meet the need for rapid assembly, the soundproof cabin is divided into multiple smaller cabins for easy transport and handling. These smaller cabins are pre-assembled at the factory. During on-site assembly, the smaller cabins are then sequentially joined together to form a larger cabin, thus meeting the requirement for rapid assembly. For example, Chinese patent application CN113302367A, entitled "Mobile Cabin with Ventilation System and Ventilation Method Thereof," describes a modular cabin that can accommodate 1-2 people. This cabin can be connected to other cabins using fasteners to form modular cabin modules, allowing the modules to accommodate more users.

[0004] The aforementioned soundproof cabins have the following drawbacks during actual installation: When splicing the cabins, the two cabins must be aligned at the splicing point before being fastened with fasteners; otherwise, the structural stability and sound insulation performance of the soundproof cabin will be affected. However, the ground at the construction site is often uneven, making it difficult for installers to align the two cabins at once. The position of the cabins needs to be constantly adjusted during the installation process, which is troublesome, time-consuming, and labor-intensive, and cannot meet the needs of rapid assembly. Moreover, the structural stability of the assembled soundproof cabin is generally poor. Summary of the Invention

[0005] The technical problem to be solved by this application is to overcome the defects of the above-mentioned related technologies and provide a soundproof cabin that can be quickly assembled, is simple to operate, saves time and effort, and has good structural stability.

[0006] The technical solution of this application is to provide a soundproof cabin with the following structure: including at least two cabins: a first cabin and a second cabin, wherein at least one side of the first cabin is open, and a first splicing member is connected to the open portion circumferentially, the first splicing member having an inclined first mating surface along its length; the second cabin is open on the side opposite to the first cabin, and a second splicing member is connected to the open portion circumferentially, the second splicing member having an inclined second mating surface along its length that mates with and fits against the first mating surface; the soundproof cabin further includes a fastening element that connects the first splicing member and the second splicing member, for pressing the first mating surface and the second mating surface together to splice the first cabin and the second cabin into a whole.

[0007] In some embodiments, the first splicing member has a recessed portion, and the inner peripheral wall of the recessed portion forms the first mating surface; the second splicing member has a protrusion that engages with the recessed portion, and the outer peripheral wall of the protrusion forms the second mating surface; when the protrusion is inserted into the recessed portion, the first mating surface and the second mating surface are in contact.

[0008] In some embodiments, the base of the recessed portion is provided with a first stop portion, and the first stop portion is circumferentially connected to a first sealing body; the base of the protruding portion is provided with a second stop portion, and the second stop portion is circumferentially connected to a second sealing body; the outer end face of the second splice is sealed with the first sealing body, and the outer end face of the first splice is sealed with the second sealing body.

[0009] In some embodiments, the soundproof cabin further includes a positioning pin connected to the first splicing component or the second splicing component and capable of axial movement, wherein the positioning pin has a conical surface, and the second splicing component or the first splicing component has a positioning hole through which the positioning pin passes; the conical surface of the positioning pin abuts against the inner wall of the positioning hole, and is used to press the second splicing component and the first splicing component together when the positioning pin moves axially.

[0010] In some embodiments, the fastening element is arranged along the height direction of the first splice or the second splice, and the free end of the fastening element passes through the second splice and is threadedly connected to the first splice, or the free end of the fastening element passes through the first splice and is threadedly connected to the second splice. During the tightening process of the fastening element, the first splice and the second splice move towards each other or have a tendency to move towards each other, so that the first sealing body and the second sealing body are pressed together.

[0011] In some embodiments, each of the cabins includes a wall panel assembly, a bottom assembly, and a top assembly, and the wall panel assembly, the bottom assembly, and the top assembly are joined together to form a cabin that is open on at least one side.

[0012] In some embodiments, each of the cabins includes a lower cabin and an upper cabin. The lower cabin includes a bottom assembly, a telescopic column, and a lower wall panel. The bottom assembly, telescopic column, and lower wall panel are arranged to form the lower cabin, which is open at the top and at least one side. The upper cabin includes a top assembly and an upper wall panel. The top assembly is connected to the telescopic column. When the top assembly is in an extended state, one end of the upper wall panel is connected to the top assembly, and the other end is connected to the lower cabin. The top assembly, upper wall panel, and telescopic column are arranged to form the upper cabin, which is open at the bottom and at least one side. The open side of the upper cabin is aligned vertically with the open side of the lower cabin.

[0013] In some embodiments, the lower cabin and the upper cabin are provided with hatches on the side walls on the same side.

[0014] In some embodiments, each of the cabins is connected to a pulley at its bottom.

[0015] In summary, the soundproof cabin proposed in this application has the following advantages compared with related technologies: When the first and second cabins are assembled, the first and second mating surfaces of the two cabin splicing components are fitted together, and then the first and second splicing components are fastened by fastening elements; since both splicing components are arranged circumferentially along the open part of the cabin, and the first and second mating surfaces on the two splicing components are inclined, when the first and second mating surfaces of the two splicing components are fitted together and move towards each other to the limit position or the preset installation position, the first and second cabins can be automatically aligned, thereby realizing the rapid assembly of the soundproof cabin, which is simple to operate and saves time and effort; moreover, when the fastening elements fasten the first and second splicing components, the first and second splicing components move towards each other or have a tendency to move towards each other under the cooperation of the inclined mating surfaces, which can further squeeze and press the first and second splicing components together, making the connection between the first and second cabins more firm and stable.

[0025] First, those skilled in the art should understand that these embodiments are merely used to explain the technical principles of the embodiments of this application and are not intended to limit the scope of protection of the embodiments of this application. Those skilled in the art can make adjustments as needed to adapt to specific application scenarios.

[0026] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application based on the specific circumstances.

[0027] In the embodiments of this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0028] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0029] Referring to Figures 1 to 5, this application discloses a soundproof cabin, which is composed of two cabins spliced ​​together. In this embodiment, the two cabins include a first cabin 1 and a second cabin 2. Both the first cabin 1 and the second cabin 2 can be used as independent cabins. Each cabin includes a wall panel assembly 4, a bottom assembly 3 and a top assembly 5. The lower end of the wall panel assembly 4 is connected to the bottom assembly 3, and the upper end of the wall panel assembly 4 is connected to the top assembly 5. The bottom assembly 3 is also called the base plate, and the top assembly 5 is also called the top plate, ceiling, etc.

[0030] It is understandable that the first compartment 1 and the second compartment 2 of the soundproof cabin can be assembled separately at the factory, or the two compartments can be assembled separately on the construction site to form two independent first compartment 1 and second compartment 2. During installation, the assembled first compartment 1 and second compartment 2 are simply spliced ​​together to form a complete soundproof cabin. The size of the first compartment 1 and the second compartment 2 is suitable for accommodating one person, that is, the size of a single-person cabin. After being spliced ​​together, they can form a double-person soundproof cabin for two people.

[0031] For example, as shown in Figures 1, 4 and 5, each compartment is arranged in a cuboid shape, and each compartment includes a bottom component 3, a top component 5 and a wall panel assembly 4 consisting of three wall panels. That is, the three wall panels, the bottom component 3 and the top component 5 together enclose a compartment with one side open. After the first compartment 1 and the second compartment 2 are spliced ​​together, at least one of the wall panels is set as a door.

[0032] It is easy to understand that the most basic feature of this soundproof cabin is sound insulation. Therefore, the bottom component 3, top component 5, and wall panel assembly 4 of each cabin are functional components for sound insulation. Taking the wall panel assembly 4 as an example, its structure generally includes a metal frame, sound insulation material connected within the metal frame, and outer and inner panels respectively connected to the outside and inside of the metal frame. To improve sound insulation performance, the joints between the functional components are sealed or soundproofed, which will not be described in detail in this embodiment. Similarly, to achieve diverse and light-transmitting designs for the soundproof cabin, at least one wall panel of the wall panel assembly 4 can be set as a transparent wall panel made of glass.

[0033] Understandably, in order to meet the user's functional needs, the soundproof cabin also includes necessary electrical components and furniture. For example, in this embodiment, an exhaust fan and lighting are connected to the top component 5, a power junction box and a switch are installed in the wall panel assembly 4, and a table is connected to the inner wall of the wall panel assembly 4.

[0034] In other embodiments, to meet users' demand for large-sized soundproof cabins, the cabin can be configured with three, four, five, or more compartments. During use, these compartments are joined together to form a larger soundproof cabin. It is understood that when the number of compartments exceeds three, the middle compartment needs to have two open sides to allow the other two compartments to be joined, while the compartments on either side only need to have one open side.

[0035] Therefore, in this embodiment, at least one side of the first compartment 1 is open, and a first splicing component 100 is connected circumferentially to the open portion. The second compartment 2 is open on the side opposite to the first compartment 1, and a second splicing component 200 is connected circumferentially to the open portion. To enable the first compartment 1 and the second compartment 2 to align quickly and accurately during assembly, thus meeting the rapid assembly requirements of the soundproof compartment, further in this embodiment, as shown in Figures 3, 4, and 5, the first splicing component 100 has a first engagement surface 102 inclined along its length, and the second splicing component 200 has a second engagement surface 202 inclined along its length and fitting against the first engagement surface 102. The soundproof compartment also includes a fastening element 6, which connects the first splicing component 100 and the second splicing component 200, and is used to press the first engagement surface 102 and the second engagement surface 202 together to splice the first compartment 1 and the second compartment 2 into a whole. Specifically, the left-right direction in Figure 2 is defined as the length direction.

[0036] In the aforementioned embodiment, when the first compartment 1 and the second compartment 2 are assembled, the first mating surface 102 of the two compartment splicing parts is made to mate and fit with the second mating surface 202, and then the first splicing part 100 and the second splicing part 200 are fastened by the fastening element 6; since both splicing parts are arranged circumferentially along the open part of the compartment, and the first mating surface 102 and the second mating surface 202 on the two splicing parts are inclined, the first mating surface 102 and the second mating surface 202 of the two splicing parts are mated and fit together and move towards each other to the limit position. When the installation position is preset, the first compartment 1 and the second compartment 2 can be automatically aligned, thereby enabling rapid assembly of the soundproof compartment. The operation is simple, time-saving, and labor-saving. Moreover, when the fastening element 6 fastens the first splicing piece 100 and the second splicing piece 200, the first splicing piece 100 and the second splicing piece 200 move towards each other or have a tendency to move towards each other under the cooperation of the inclined joint surface. This can further compress and tighten the first splicing piece 100 and the second splicing piece 200, making the connection between the first compartment 1 and the second compartment 2 more firm and stable.

[0037] Furthermore, in this embodiment, in order to achieve rapid alignment when the first compartment 1 and the second compartment 2 are spliced, as shown in Figures 3, 4 and 5, the first splicing member 100 has a recessed portion 101, and the inner peripheral wall of the recessed portion 101 forms a first mating surface 102; the second splicing member 200 has a protruding portion 201 that is inserted into the recessed portion 101, and the outer peripheral wall of the protruding portion 201 forms a second mating surface 202; when the protruding portion 201 is inserted into the recessed portion 101, the first mating surface 102 and the second mating surface 202 are in contact. That is, when the first compartment 1 and the second compartment 2 are spliced, the protrusion 201 of the second splicing piece 200 only needs to be inserted into the recess 101 of the first splicing piece 100 to make the first joint surface 102 fit with the second joint surface 202. Since the first joint surface 102 and the second joint surface 202 are inclined surfaces that fit together, when the first compartment 1 and the second compartment 2 move towards each other, the first compartment 1 and the second compartment 2 can automatically align under the guidance of the inclined surfaces. Even if the ground of the construction site is uneven, the first compartment 1 and the second compartment 2 can be quickly aligned and the two are joined more tightly. When the fastening element 6 fastens the first splicing piece 100 and the second splicing piece 200, the squeezing of the fastening element 6 makes the first splicing piece 100 and the second splicing piece 200 fit tighter and tighter, so that the connection between the first compartment 1 and the second compartment 2 is more stable and firm.

[0038] In other embodiments, the recessed portion 101 and the protruding portion 201 can be interchanged between the first splicing member 100 and the second splicing member 200, that is, the recessed portion is provided on the second splicing member 200 and the protruding portion is provided on the first splicing member 100.

[0039] In this embodiment, to ensure that the joint between the first splicing component 100 and the second splicing component 200 is waterproof, soundproof, and airtight after splicing, as shown in Figures 3, 4, and 5, a first stop 103 is provided at the base of the recessed portion 101, and a first sealing body 104 is connected to the first stop 103 circumferentially; a second stop 203 is provided at the base of the protruding portion 201, and a second sealing body 204 is connected to the second stop 203 circumferentially; the outer end face of the protruding portion 201 is sealed with the first sealing body 104, and the outer end face of the first splicing component 100 is sealed with the second sealing body 204. When the first compartment 1 and the second compartment 2 are assembled, the protrusion 201 of the second splicing component 200 is fitted into the recess 101 of the first splicing component 100, so that the first splicing component 100 and the second splicing component 200 are spliced ​​together in a concave-convex fit or complementary manner, so that the splicing seam of the first splicing component 100 and the second splicing component 200 is arranged in a labyrinthine manner. In addition, the first sealing body 104 connected to the first stop part 103 at the base of the recess 101 abuts and seals against the outer end face of the protrusion 201, and the outer end face of the recess 101 abuts and seals against the second sealing body 204 on the second stop part 203, so that the splicing point of the first splicing component 100 and the second splicing component 200 has two seals. Therefore, after the first compartment 1 and the second compartment 2 are assembled, the soundproof compartment not only has good sealing performance at the splicing point, but also has a large contact area at the splicing point, resulting in good stability and excellent sound insulation performance after the joint.

[0040] In this embodiment, the fastening element 6 is a bolt with a post head. Multiple fastening elements 6 are arranged at circumferential intervals along the first splice 100 or the second splice 200. Specifically, as shown in Figure 3, each fastening element 6 is arranged along the height direction of the first splice 100 or the second splice 200. The free end of the fastening element 6 passes through the second splice 200 and is threaded to the first splice 100, or the free end of the fastening element 6 passes through the first splice 100 and is threaded to the second splice 200. During the tightening process of the fastening element 6, the first splice 100 and the second splice 200 move towards each other and squeeze each other or have a tendency to move towards each other. Under the guiding action of the inclined first mating surface 102 and the second mating surface 202, the outer end face of the protrusion 201 is pressed against the first sealing body 104 and the outer end face of the recess 101 or the first splice 100 is pressed against the second sealing body 204. Specifically, the vertical direction in Figure 3 is defined as the height direction mentioned above.

[0041] Furthermore, in this embodiment, the soundproof cabin also includes a positioning pin 7 connected to the first splicing member 100 or the second splicing member 200 and capable of axial movement. The positioning pin 7 is provided with a conical surface 700, and the second splicing member 200 or the first splicing member 100 is provided with a positioning hole 105 for the positioning pin 7 to pass through. The conical surface 700 of the positioning pin 7 abuts against the inner wall of the positioning hole 105, which is used to press the second splicing member 200 and the first splicing member 100 together when the positioning pin 7 moves axially. The positioning pin 7 can be set at the four corners of the first splicing component 100 or the second splicing component 200. Before tightening the fastening element 6, the positioning pin 7 is installed first. Under the action of the positioning pin 7, the first splicing component 100 and the second splicing component 200 are pressed together. This prevents the first splicing component 100 and the second splicing component 200 from loosening or shifting when tightening the fastening element 6. This ensures that the first compartment 1 and the second compartment 2 can always remain aligned after the fastening element 6 is installed.

[0042] For example, referring to Figure 6, the positioning pin 7 is arranged along the height direction of the first splicing member 100 or the second splicing member 200, or the axis of the positioning pin 7 is parallel to the axis of the fastening element 6; the free end of the positioning pin 7 extends outward, and a conical surface 700 is provided at the free end; the positioning pin 7 is threaded onto the protrusion 201 of the second splicing member 200 and passes through the first splicing member 100, so that the conical surface 700 of the free end of the positioning pin 7 abuts against the inner wall of the positioning hole 105 on the first splicing member 100; when the positioning pin 7 is rotated, so that the positioning pin 7 moves axially toward the first splicing member 100, the conical surface 700 pushes the positioning hole 105 toward the side of the second splicing member 200, so that the first splicing member 100 moves toward the second splicing member 200 or has a tendency to move toward the second splicing member 200. Thus, the first splicing member 100 and the second splicing member 200 are pressed together.

[0043] In other embodiments, the locating pin 7 may also be tightly fitted with the mounting hole on the protrusion 201, and an axial force may be applied to the locating pin 7 to make the locating pin 7 move axially.

[0044] Furthermore, in this embodiment, in order to facilitate the splicing of the first compartment 1 and the second compartment 2, pulleys are connected to the bottom of each compartment. The first compartment 1 and the second compartment 2 are moved by sliding, so that the splicing parts of the first compartment 1 and the second compartment 2 can be quickly aligned and spliced, and the operation is convenient and labor-saving.

[0045] In some embodiments, to further reduce the packaging volume of each compartment, save packaging costs, and facilitate entry into homes and elevators, each compartment is divided into upper and lower compartments, i.e., each compartment includes a lower compartment and an upper compartment. The lower compartment includes a bottom component 3, a telescopic column 402, and a lower wall panel 400. The bottom component 3, the telescopic column 402, and the lower wall panel 400 are arranged to form a lower compartment that is open at the top and at least one side. The upper compartment includes a top component 5 and an upper wall panel 401. The top component 5 is connected to the telescopic column 402. When the top component 5 is in the extended state, one end of the upper wall panel 401 is connected to the top component 5, and the other end is connected to the lower compartment. The top component 5, the upper wall panel 401, and the telescopic column 402 are arranged to form an upper compartment that is open at the bottom and at least one side. The open side of the upper compartment is aligned vertically with the open side of the lower compartment. In this embodiment, each cabin can be reduced in volume in the height direction, which can further reduce the packaging volume of the cabin, save packaging costs, and make the silent cabin more convenient to transport.

[0046] For example, referring to Figure 7, there are four telescopic columns 402, each consisting of nested outer and inner tubes that slide relative to each other. The outer tubes of the four telescopic columns 402 are fixedly connected to the four corners of the bottom component 3, and three lower wall panels 400 are connected between two adjacent outer tubes, so that the bottom component 3, the telescopic columns 402, and the lower wall panels 400 form a lower compartment that is open at the top and at least one side. The upper ends of the inner tubes of the four telescopic columns 402 are connected to the four bottom corners of the top component 5. During packaging, the telescopic column 402 extends and retracts, and the top component 5 can be pressed onto the top of the lower compartment. During on-site assembly, the telescopic column 402 is unfolded and in the unfolded state. At this time, the upper wall panel 401 is connected between the inner tubes of two adjacent telescopic columns 402, with the upper end of the upper wall panel 401 connected to the top component 5 and the lower end of the upper wall panel 401 connected to the upper end of the lower compartment or the lower wall panel 400. Under the constraint of the upper wall panel 401, the telescopic column 402 remains in the unfolded state. When the upper compartment is in the unfolded state relative to the lower compartment, the splicing parts are connected to complete the assembly of a single compartment.

[0047] In the aforementioned embodiment, a hatch is provided on the side wall of the lower and upper hulls on the same side. The upper wall panel 401 and the lower wall panel 400 of the hatch are formed into a single hatch after the upper and lower hulls are assembled.
