Description

Technical Field

[0001] This utility model relates to the field of acoustic engineering technology, and in particular to a silent door assembly. Background Technology

[0002] In modern life, people have an increasingly strong demand for quiet living and working environments. Traditional doors, due to their simple structure and common materials, have significant shortcomings in sound insulation and noise reduction, failing to meet people's pursuit of quiet spaces. In-depth acoustic research has revealed that sound travels through both air and solids, pointing the way for the development of silent door systems. Simultaneously, advancements in materials science have brought about new sound insulation materials such as damping sound insulation felt and sound-absorbing cotton, as well as high-performance wood, metal, and composite materials, providing a material basis for improving sound insulation. Furthermore, the rise of smart homes has prompted the integration of smart elements into silent door systems, meeting people's diverse needs for door functionality. Against this backdrop, silent door systems have emerged and continue to develop and improve.

[0003] While some existing silent door systems aim to create a tranquil space for users and incorporate noise reduction measures in their design and material selection, they have revealed some drawbacks in actual use. Their mechanical locks produce noticeable noise during the rebound process due to the rigid collision and friction of internal components. This sound is particularly jarring in quiet environments, severely disrupting the tranquil atmosphere that a silent door system should create. Meanwhile, while widely used magnetic locks offer improvements in noise reduction compared to traditional locks, their durability is a concern. Over time, changes in ambient temperature and humidity, as well as frequent opening and closing, easily demagnetize magnetic locks, weakening their magnetic force. This not only threatens the door's security performance but also significantly shortens the product's overall lifespan, causing considerable inconvenience to users. Therefore, we propose a silent door system to address the aforementioned problems. Utility Model Content

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of the present invention, to avoid obscuring the purpose of these documents, and such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] Therefore, the purpose of this utility model is to provide a silent door assembly that can solve some problems of existing silent door assemblies. Although they are designed to create a quiet space for users and incorporate certain sound-dampening measures in their design and material selection, some drawbacks have been exposed in actual use. During the rebound process of the mechanical lock, the rigid collision and friction of the internal components produce a noticeable noise. This sound is particularly jarring in quiet environments, severely disrupting the tranquil atmosphere that the silent door assembly should create. Meanwhile, while widely used magnetic locks are an improvement in sound dampness compared to traditional locks, their durability is a concern. With prolonged use, changes in ambient temperature and humidity, as well as frequent opening and closing, easily cause magnetic locks to demagnetize, weakening the lock's magnetic force. This not only threatens the door's security performance but also significantly shortens the overall lifespan of the product, causing numerous problems for users.

[0006] To solve the above-mentioned technical problems, this utility model provides a silent door assembly, which adopts the following technical solution: It includes a door frame, inside which a door panel is installed via hinges. A first latch receiving groove is provided inside the door panel near its right edge. Corresponding to the position of the first latch receiving groove on the door panel, a second latch receiving groove is provided on the inner side of the door frame that is in contact with the door panel. Inside the door panel is a transmission groove with a specific bending line. The head of the transmission groove is located directly in front of the door panel, and the tail of the transmission groove extends to the left side of the first latch receiving groove. A first trigger slider is movably installed at the head of the transmission groove, and a second trigger slider is movably installed at the tail of the transmission groove. The second trigger slider is directly connected to the latch. Several transmission beads are movably arranged within the transmission groove.

[0007] Optionally, the door panel has a stepped slot on the side facing the door frame, and the door frame has a stepped strip that matches the stepped slot. A sound-absorbing rubber strip is fixedly embedded in the stepped slot, and a magnetic strip is fixedly encapsulated inside the sound-absorbing rubber strip. A sound-absorbing rubber strip and an internal magnetic strip are also fixedly embedded in the corresponding position on the door frame.

[0008] Optionally, a buffer damper is axially connected and installed on the door panel, and a limit block is fixedly installed directly below the door frame. The limit block cooperates with the buffer damper. When the door is opened, the buffer damper elastically pops out inward. When the door is closed forcefully, the buffer damper cooperates with the limit block to slow down the door and reduce closing noise.

[0009] Optionally, the hinge is made of a low-friction material and has a precision mechanical structure. The sliding stroke of the trigger slider in the transmission groove inside the door panel matches the extension and retraction stroke of the latch in the second latch receiving groove to ensure accurate power transmission and achieve the locking function.

[0010] Optionally, the diameter of the transmission bead is adapted to the inner diameter of the transmission groove, and the transmission bead can roll smoothly in the transmission groove to ensure the effectiveness of power transmission.

[0011] Optionally, the sound-absorbing rubber strip is made of rubber material with good sound absorption and elasticity, which can effectively absorb and block the transmission of sound, and silent door handles are installed on both the front and rear sides of the door panel.

[0012] In summary, this utility model has at least one of the following beneficial effects: 1. By setting a transmission groove, transmission bead, first trigger slider, second trigger slider, lock tongue, and return spring between the door frame and the door panel, and rationally arranging the positions of each component, such as the head of the transmission groove being located directly in front of the door panel and the tail extending to the left side of the first lock tongue receiving groove, a precise and stable locking purpose is achieved. Compared with traditional mechanical locks, it avoids the obvious noise caused by the rigid collision and friction of internal components when the lock rebounds, and will not disrupt the quiet atmosphere in a quiet environment due to the closing action; compared with magnetic locks, it does not have the problem of demagnetization due to changes in environmental temperature and humidity and frequent opening and closing over a long period of use, ensuring that the door lock suction force remains stable and effectively maintaining the door's security performance. When the door panel is closed, the first trigger slider collides with the door frame, and the power is transmitted through the transmission bead to the second trigger slider, causing the lock tongue to insert into the second lock tongue receiving groove, ensuring reliable door locking function, convenient operation, and improving the safety, durability, and practicality of the door assembly.

[0013] 2. By installing stepped slots and stepped strips on the door panel and door frame respectively, fixing and embedding sound-absorbing rubber strips in the slots and sealing magnetic strips, and installing a buffer damper on the door panel and a limit block at the bottom of the door frame, the sound insulation and shock absorption of the door assembly are enhanced. When the door panel is closed, the magnetic strips adhere to each other, the sound-absorbing rubber strips absorb and block sound transmission, and when the door is slammed shut, the buffer damper and the limit block work together to slow down the closing, reducing closing noise and creating a quiet environment, thus improving the user experience.

[0021] The following is in conjunction with the appendix Figure 1-4 The present invention will be described in further detail below.

[0022] Example 1, refer to Figure 1-4 In this embodiment, in order to address some existing silent door assembly issues, while adhering to the initial intention of creating a tranquil space for users, certain sound-dampening measures have been taken in design and material selection. However, some drawbacks have been exposed in actual use. During the rebound process of its mechanical lock, the rigid collision and friction of its internal components produce a noticeable noise. This sound is particularly jarring in quiet environments, severely disrupting the tranquil atmosphere that the silent door assembly should create. Meanwhile, while widely used magnetic locks offer improvements in sound dampness compared to traditional locks, their durability is a concern. During long-term use, changes in environmental temperature and humidity, as well as frequent opening and closing actions, easily cause magnetic locks to demagnetize, weakening the lock's suction force. This not only threatens the door's security performance but also significantly shortens the overall lifespan of the product, causing numerous problems for users. This utility model discloses a silent door assembly...

[0023] The system includes a door frame 1, inside which a door panel 2 is installed via hinges 3. A first latch receiving groove 4 is located near the right edge of the door panel 2. A second latch receiving groove 5 is located on the inner side of the door frame 1 corresponding to the first latch receiving groove 4, where it fits against the door panel 2. Inside the door panel 2 is a transmission groove 6 with a specific bending path. The head of the transmission groove 6 is located directly in front of the door panel 2, and the tail of the transmission groove 6 extends to the left side of the first latch receiving groove 4. A first trigger slider 7 is movably installed at the head of the transmission groove 6, and a second trigger slider 8 is movably installed at the tail of the transmission groove 6. The second trigger slider 8 is directly connected to the latch 9. Several transmission beads 10 are movably arranged within the transmission groove 6. By connecting the door panel 2 inside the door frame 1 via hinges 3, the system ensures that the door panel 2 can rotate flexibly and is securely connected. A first latch receiving groove 4 is provided near the right edge of the door panel 2, and a second latch receiving groove 5 is provided at the corresponding position of the door frame 1, providing accurate locking space for the latch 9. A transmission groove 6 with a specific bending line is provided, with its head positioned directly in front of the door panel 2 and its tail extending to the left side of the first latch receiving groove 4, planning a reasonable path for power transmission. A first trigger slider 7 and a second trigger slider 8 are respectively movably installed at the head and tail of the transmission groove 6, and the second trigger slider 8 is directly connected to the latch 9, ensuring the continuity of power transmission. Several transmission beads 10 are movably arranged in the transmission groove 6. When the door panel 2 is closed, the collision force received by the first trigger slider 7 can be effectively transmitted to the second trigger slider 8, thereby driving the latch 9 to lock, achieving the purpose of precise and stable locking, and realizing the safe, reliable and convenient operation effect of the silent door assembly.

[0024] A step groove 11 is provided on the side of the door panel 2 facing the door frame 1. A step strip 12 adapted to the step groove 11 is provided on the door frame 1. A sound-absorbing rubber strip 13 is fixedly embedded in the step groove 11. A magnetic strip 14 is fixedly encapsulated inside the sound-absorbing rubber strip 13. A sound-absorbing rubber strip 13 and its internal magnetic strip 14 are also fixedly embedded in the corresponding position on the door frame 1. By providing a step groove 11 on the side of the door panel 2 facing the door frame 1, and providing a step on the door frame 1 that is adapted to it, a step groove 11 is provided on the door panel 2. The door panel 12 is fitted with a sound-absorbing rubber strip 13, which is fixedly embedded in the stepped groove 11. A magnetic strip 14 is also fixedly encapsulated inside the sound-absorbing rubber strip 13. The same setting is also made at the corresponding position of the door frame 1. This achieves the purpose of enhancing the tightness of the door panel 2 and the door frame 1 in closing and the purpose of sound insulation and noise reduction. When the door panel 2 is closed, the two sets of magnetic strips 14 attract and stick to each other, making the door assembly more stable. The sound-absorbing rubber strip 13 plays a role in buffering and absorbing noise, effectively improving the quietness effect.

[0025] A buffer damper 15 is axially connected and installed on the door panel 2, and a limit block 16 is fixedly installed directly below the door frame 1. The limit block 16 cooperates with the buffer damper 15. When the door is opened, the buffer damper 15 springs inward elastically. When the door is closed forcefully, the buffer damper 15 and the limit block 16 cooperate to slow down the closing of the door, reducing closing noise. By axially connecting and installing the buffer damper 15 on the door panel 2 and fixing the limit block 16 directly below the door frame 1, and making the two cooperate with each other, the purpose of controlling the opening and closing speed of the door and reducing the closing impact force is achieved. This realizes that when the door is opened, the buffer damper 15 can spring inward elastically, and when the door is closed forcefully, the buffer damper 15 and the limit block 16 cooperate to slow down the closing of the door, significantly reducing closing noise and creating a quiet environment.

[0026] The hinge 3 uses a low-friction coefficient material and a precision mechanical structure. The sliding stroke of the trigger slider in the transmission groove 6 inside the door panel 2 matches the extension stroke of the latch 9 in the second latch receiving groove 5. This ensures accurate power transmission to achieve the locking function. By using the hinge 3 with a low-friction coefficient material and a precision mechanical structure, and matching the sliding stroke of the trigger slider in the transmission groove 6 inside the door panel 2 with the extension stroke of the latch 9 in the second latch receiving groove 5, the noise of the hinge 3 rotation is reduced and the locking action is ensured to be accurate. This results in quiet opening and closing of the door panel 2, and accurate power transmission so that the latch 9 can smoothly insert into the second latch receiving groove 5 to complete the locking, thus improving the user experience and security of the door assembly.

[0027] The diameter of the transmission bead 10 is matched with the inner diameter of the transmission groove 6, allowing the transmission bead 10 to roll smoothly within the transmission groove 6, thus ensuring the effectiveness of power transmission. By matching the diameter of the transmission bead 10 with the inner diameter of the transmission groove 6, the purpose of ensuring the smooth rolling of the transmission bead 10 within the transmission groove 6 is achieved, enabling the effective transmission of power within the transmission groove 6. This, in turn, ensures that the latch 9 can accurately respond to the closing action of the door panel 2 to complete the locking function, thereby improving the locking stability and reliability of the silent door assembly.

[0028] The sound-absorbing rubber strip 13 is made of rubber material with good sound absorption and elasticity, which can effectively absorb and block the transmission of sound. Silent door handles 17 are installed on both the front and back sides of the door panel 2. By using rubber material with good sound absorption and elasticity to make the sound-absorbing rubber strip 13, and installing silent door handles 17 on both the front and back sides of the door panel 2, the sound insulation effect of the door assembly is enhanced and the noise of opening and closing the door is reduced. It effectively absorbs and blocks the transmission of sound, and is also quiet when using the door handle to open and close the door, creating a quiet environment in all aspects.

[0029] The door assembly collision-type locking mechanism based on the power transmission of the transmission bead 10: When the door panel 2 is in the closed position, the first trigger slider 7 located at the head of the transmission groove 6 inside the door panel 2 collides with the door frame 1. The mechanical kinetic energy generated by the collision is transmitted through the rolling transmission bead 10 inside the transmission groove 6, accurately transmitting the power to the second trigger slider 8 at the tail of the transmission groove 6. After receiving the power, the second trigger slider 8 generates a linear displacement. Due to its rigid connection with the latch 9, it drives the latch 9 to move synchronously, so that the latch 9 accurately inserts into the second latch receiving groove 5 opened on the inner side of the door frame 1, completing the locking function of the door assembly.

[0030] The specific working principle is as follows: By setting up a transmission groove 6, transmission bead 10, first trigger slider 7, second trigger slider 8, lock tongue 9, and return spring between the door frame 1 and the door panel 2, and by rationally arranging the positions of each component, such as the head of the transmission groove 6 being located directly in front of the door panel 2 and the tail extending to the left side of the first lock tongue receiving groove 4, a precise and stable locking purpose is achieved. Compared with traditional mechanical locks, it avoids the obvious noise caused by the rigid collision and friction of internal components when the lock rebounds, and will not disrupt the quiet atmosphere in a quiet environment due to the closing action; compared with magnetic locks, it does not have the problem of demagnetization due to long-term use, changes in environmental temperature and humidity, and frequent opening and closing, ensuring that the door lock suction force remains stable and effectively maintaining the door's security performance. When the door panel 2 is closed, the first trigger slider 7 collides with the door frame 1, and the power is transmitted through the transmission bead 10 to the second trigger slider 8, which drives the lock tongue 9 to insert into the second lock tongue receiving groove 5, ensuring reliable door locking function, convenient operation, and improving the door assembly's security, durability, and practicality. By setting stepped slots 11 and stepped strips 12 on the door panel 2 and door frame 1 respectively, fixing and embedding sound-absorbing rubber strips 13 in the slots and encapsulating magnetic strips 14, and installing a buffer damper 15 on the door panel 2 and a limiting block 16 at the bottom of the door frame 1, the sound insulation effect and shock absorption of the door assembly are enhanced. When the door panel 2 is closed, the magnetic strips 14 adhere to each other, and the sound-absorbing rubber strips 13 absorb and block sound transmission. Simultaneously, when the door is slammed shut, the buffer damper 15 and the limiting block 16 work together to slow down the closing of the door, reducing closing noise, creating a quiet environment, and improving the user experience.

[0031] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
