[0038] The technical solutions of the embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0039] like Figures 1 to 9As shown, this utility model provides a magnetic silent door, including a door leaf 1, a door frame 2, a first sealing component 3, and a second sealing component 4. One side of the door leaf 1 is hinged to the inner side of the door frame 2, allowing the door leaf 1 to rotate on the door frame 2. The door leaf 1 can face inwards or outwards. During the closing process of the door leaf 1, the first sealing component 3 and the second sealing component 4 achieve buffering and noise reduction. The edge of the door leaf 1 is provided with a mounting groove 10. When the door leaf 1 rotates outwards, the door leaf 1 faces the interior panel. Mounting grooves 10 are provided on the top and sides of the door leaf 1, and the mounting grooves 10 are L-shaped to facilitate magnetic attraction and buffering with the door frame 2. The door frame 2 has a door stop 20 extending outwards and located within the mounting groove 10. The door frame 2 is a long strip-shaped structure and can generally be fixed to the door opening of the wall 6 by adhesive. The door frame 2 is installed on the side walls and top wall of the door opening, and the door stop 20 on the door frame 2 faces the door leaf. The door leaf 1 extends, and a portion of the door stop 20 is located within the mounting groove 10. The first sealing component 3 is disposed on the mounting groove 10, which has a first mounting surface and a second mounting surface perpendicular to each other. The door stop 20 has an insertion groove 20a on the side facing the second mounting surface, and the second sealing component 4 is disposed on the insertion groove 20a. The first sealing component 3 forms a buffer structure on the first mounting surface and a magnetic attraction structure on the second mounting surface. The second sealing component 4 is magnetically connected to the magnetic attraction structure. When the door leaf 1 is closed, the buffer structure of the first sealing component 3 abuts against the door stop 20 to achieve a first sealed space between the door leaf 1 and the door frame 2, increasing the noise reduction effect. The buffer structure can also absorb the impact force generated between the door leaf 1 and the door frame 2, preventing the door leaf 1 from hitting the door frame 2. The magnetic attraction structure of the first sealing component 3 abuts against the second sealing component 4 to achieve a second sealed space between the door leaf 1 and the door frame 2, further increasing the noise reduction effect. It can also lock the door leaf 1 onto the door frame 2 through magnetic attraction.

[0040] In this embodiment, the first mounting surface is parallel to the decorative surface of the door leaf 1. The magnetic structure on the first mounting surface is arranged opposite to the magnetic connection of the second sealing component 4. Under this arrangement, the magnetic structure on the door leaf 1 and the second sealing component 4 of the door frame 2 are matched at 90°. When the door leaf 1 is opened, the applied force is less than that of the inclined magnetic strip, making it easier for people with weaker physical strength to push open the door leaf 1.

[0041] Compared with the prior art, the magnetic silent door provided by the utility model has a double-sealed buffer silent structure in which the first sealing component 3 located in the mounting groove 10 and the second sealing component 4 located in the insertion groove 20a can buffer the impact and collision between the door leaf 1 and the door frame 2, reduce the noise generated when closing the door, and block the transmission path of sound waves to achieve better sound insulation effect.

[0042] Based on the above specific embodiments, in order to improve the assembly efficiency of the first sealing component 3 and the door leaf 1, and to ensure the applicability and durability of the first sealing component 3, the first sealing component 3 includes a first frame 30, an elastic element 31, and a first magnetic strip 2. The first frame 30 is arranged in an L-shape and has a first groove 30a and a second groove 30b that pass through both ends of its axial direction. The first groove 30a is opposite to the end face of the door stop 20, and the second mounting groove 10 is opposite to the insertion groove 20a. The elastic element 31 is accommodated in the first groove 30a and contacts and abuts against the door stop 20. The first magnetic strip 2 is embedded in the second groove 30b.

[0043] Specifically, the first frame 30 is made of lightweight materials, such as aluminum alloy or polyamide, and has the characteristics of being lightweight, having moderate strength, and being easy to process. The corresponding first groove 30a and second groove 30b are formed by stamping or injection molding. Then, the elastic element 31 and the first magnetic strip 2 are installed on the first groove 30a and the second groove 30b by embedding and fixing. The first frame 30 can be fixed to the mounting groove 10 by bolts. In some embodiments, in order to ensure the firmness of the elastic element 31 and the first magnetic strip 2 and to prevent them from shaking or falling off when subjected to collisions, the first groove 30a is designed as a trapezoidal structure with a wider inner side and a narrower outer side, while the second groove 30b is designed as a T-shaped structure. When the first magnetic strip 2 in the second groove 30b is pulled by the magnetic force of the second sealing component 4 of the door stop 20, the first magnetic strip 2 can be firmly fixed to the second groove 30b by the T-shaped structure.

[0044] Furthermore, to ensure that the door stop 20 does not scrape off the elastic element 31 when the door leaf 1 opens and closes, and to improve the smoothness of the door leaf 1 closing when the elastic element 31 abuts against the door stop 20, the elastic element 31 is provided with a guide slope 31a that abuts against the door stop 20, and the door stop 20 is provided with an arc-shaped guide surface 20b that abuts against the guide slope 31a. With this configuration, the guide slope 31a of the elastic element 31 can guide the door stop 20 during the closing process of the door leaf 1. After the door stop 20 abuts against the elastic element 31, the elastic element 31 can absorb part of the kinetic energy of the door leaf 1, reducing the impact force of the door leaf 1 impacting the door frame 2, and can also form a first sealed space on the door leaf 1 with the door stop 20, increasing the sound insulation effect of the room.

[0045] Furthermore, the elastic element 31 is any one of PVC rubber strip, silicone rubber strip, TPE rubber strip, EPDM rubber strip and ABS rubber strip.

[0046] Based on the above specific embodiments, in order to ensure the magnetic attraction effect between the door leaf 1 and the door frame 2 and improve the shock absorption effect between them, the second sealing component 4 includes a second skeleton 40 and a sealing strip 41. The sealing strip 41 is connected to the second skeleton 40, and the second skeleton 40 is embedded in the insertion groove 20a. The sealing strip 41 has two parallel chambers that are spaced apart from each other, and a second magnetic strip 42 is provided in each of the two chambers.

[0047] Specifically, the second frame 40 is made of plastic and is fixed to the insertion slot 20a of the door frame 2 by an embedded installation method. To ensure the firmness of the second frame 40, in some embodiments, the insertion slot 20a is designed as a T-shaped structure, and the sealing strip 41 is integrally set by two-color injection molding to achieve the second frame 40 and the sealing strip 41. With this setting, the connection strength between the second frame 40 and the sealing strip 41 can be improved. The sealing strip 41 has two chambers that pass through both ends of the axial direction of the sealing strip 41, and two second magnetic strips 42 are embedded in the chambers. When the door 1 is closed, the sealing strip 41 can be stretched and deformed under the action of magnetic attraction, so that the first magnetic strip 2 and the second sealing component 4 can make close contact, thereby forming a second sealed space on the door 1, further blocking the transmission path of sound waves and reducing the transmission of indoor and outdoor noise. In some embodiments, the two ends of the sealing strip 41 are recessed inward.

[0048] Based on the above specific implementation, the door leaf 1 includes a keel 11 and two boards 12 laid on the keel 11. The keel 11 and the two boards 12 form a cavity for filling with sound-absorbing cotton 13. The door leaf 1 is filled with sound-absorbing cotton 13. The sound-absorbing cotton 13 filling the door leaf 1 can effectively absorb sound waves.

[0049] Furthermore, the magnetic silent door also includes a wire 5. The door frame 2 is provided with a wire groove 21. The wire 5 has an insertion strip 50 inserted into the wire groove 21. The wire 5 is connected to the wall 6 with adhesive. The door frame 2 is provided with a wire groove 21. The insertion strip 50 on the wire 5 is embedded in the wire groove 21. The wire 5 is fixed to the wall 6 with expanding foam, so that the door frame 2 and the wall 6 form a third sealed space, further blocking the transmission path of sound waves between the indoor and outdoor spaces.

[0050] The various embodiments of the present invention have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
