Technical Field

[0001] This utility model relates to the field of furniture technology, specifically to a door component with better sealing and sound insulation effects. Background Technology

[0002] In existing technologies, interior door panels are usually only designed to open and close without prioritizing sealing performance. This results in poor sealing when the interior door is closed, and consequently, insufficient sound insulation, leading to a relatively poor user experience.

[0003] Therefore, how to provide a solution to overcome or alleviate the above-mentioned defects remains a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] The purpose of this invention is to provide a door assembly that has relatively better sealing, sound insulation, and noise reduction performance, thereby improving the user experience.

The door stop component is U-shaped and includes an upper stop, a left stop, and a right stop. The door leaf component has an open state and a closed state. In the closed state, at least two first sealing components are provided between the door leaf component and the upper stop, between the door leaf component and the left stop, and between the door leaf component and the right stop. The first sealing components are arranged at intervals along the inward and outward directions. At least two second sealing components are also provided at the lower end of the door leaf component. The second sealing components are also arranged at intervals along the inward and outward directions.

[0006] In the above solution, first sealing components are provided on the upper, left, and right sides of the door panel, and a second sealing component is provided on the lower side of the door panel. This ensures that the door panel is sealed from all sides, reducing sound leakage points and improving the sound insulation and noise reduction performance of the door assembly.

[0032] The directional terms mentioned in the embodiments of this utility model, such as "up", "down", "left", "right", "inner", and "outer", are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this utility model, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this utility model.

[0033] In the description of embodiments of this utility model, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0034] Please refer to Figures 1-5 , Figure 1 A cross-sectional view of the door assembly provided in the embodiment of this utility model, perpendicular to the vertical direction; Figure 2 for Figure 1 A partial view; Figure 3 A cross-sectional view of the door assembly provided in the embodiment of this utility model, perpendicular to the left and right directions; Figure 4 for Figure 3 A partial view; Figure 5 This is a schematic diagram of the corner seal.

[0035] like Figures 1-4 As shown, this utility model embodiment provides a door assembly, including a door leaf component 1000 and a door stop component 2000.

[0036] The doorstop component 2000 can be installed in a doorway in a wall, which includes an upper wall surface, a left wall surface, and a right wall surface. The doorstop component 2000 is U-shaped and includes an upper stop portion 2100, a left stop portion 2200, and a right stop portion 2300. The upper stop portion 2100 can be installed on the upper wall surface, the left stop portion 2200 can be installed on the left wall surface, and the right stop portion 2300 can be installed on the right wall surface.

[0037] The door leaf component 1000 is rotatable relative to the door stop component 2000 to switch between an open state and a closed state. In the closed state, at least two first sealing components 3000 are provided between the door leaf component 1000 and the upper stop 2100, between the door leaf component 1000 and the left stop 2200, and between the door leaf component 1000 and the right stop 2300. The first sealing components 3000 are arranged at intervals along the inward and outward directions.

[0038] The lower end of the door leaf component 1000 is also provided with at least two second sealing components 4000, which are also arranged at intervals in the inward and outward directions. Furthermore, each second sealing component 4000 is used to abut against the mounting surface P of the door assembly. The mounting surface P can be the ground or a floor surface, etc.

[0039] By adopting the above solution, in the door assembly provided in this embodiment of the present invention, the upper, left, and right sides of the door leaf component 1000 are all provided with first sealing components 3000, and the lower side of the door leaf component 1000 is provided with a second sealing component 4000. This allows for sealing around the entire perimeter of the door leaf component 1000, reducing sound leakage points and thus improving the sound insulation and noise reduction performance of the door assembly. Furthermore, both the first sealing component 3000 and the second sealing component 4000 can be arranged in at least two layers in the inward and outward directions, forming multiple seals around the perimeter of the door leaf component 1000 in both directions. This results in a better sealing effect and, consequently, a better improvement in the sound insulation and noise reduction performance of the door assembly.

[0040] In other words, the door assembly provided by this utility model embodiment can have relatively better sealing, sound insulation and noise reduction performance, which can improve the user experience.

[0041] In some alternative implementations, such as Figure 2 and Figure 4 As shown, there can be two first sealing components 3000. One of the two first sealing components 3000 can be installed on the door leaf component 1000, and the other of the two first sealing components 3000 can be installed on the door stop component 2000. In this way, the two first sealing components 3000 can be installed conveniently.

[0042] Specifically, the door leaf component 1000 may be provided with a first mounting groove 1110, the door stop component 2000 may be provided with a second mounting groove 2400, one of the two first sealing components 3000 may be provided in the first mounting groove 1110, and the other of the two first sealing components 3000 may be provided in the second mounting groove 2400. The installation method of the first sealing component 3000 in the two mounting grooves may be interference fit, bonding, or a combination of interference fit and bonding, etc., which is not limited here, as long as the reliability requirements of the connection can be met.

[0043] It should be understood that in some other implementations of this utility model, each of the first sealing components 3000 may also be installed entirely on the door leaf component 1000, or each of the first sealing components 3000 may also be installed entirely on the door stop component 2000.

[0044] In this embodiment of the invention, the first sealing component 3000 can specifically be a sealing strip, etc. The sealing strip can be made of a material with a certain elastic deformation capacity, such as rubber. When the door component 1000 is in the closed state, the sealing strip can be in a compressed state to improve its sealing and sound insulation effect.

[0045] In some alternative implementations, the second sealing member 4000 may include a lifting part and a sealing part. The sealing part may be mounted on the lifting part, which is configured to control the sealing part to move up and down to switch between an elevated position and a lowered position.

[0046] When the door panel 1000 is in the open position, the aforementioned sealing part can be in the raised position, and a gap can be provided between the sealing part and the mounting surface P. In this way, when the door panel 1000 is rotated, the friction between the door panel 1000 and the mounting surface P can be relatively small, and the rotation of the door panel 1000 can be smoother; the wear of the sealing part can also be relatively small, which is also conducive to ensuring the service life of the sealing part.

[0047] When the door panel 1000 is in the closed state, the sealing member can be in a lowered position to abut against the mounting surface P, thereby achieving a reliable seal between the door panel 1000 and the mounting surface P.

[0048] The sealing part mentioned above can also be a sealing strip.

[0049] Here, the present invention does not limit the specific structural form of the lifting part. In practical applications, those skilled in the art can choose according to specific needs, as long as it can meet the requirements of use.

[0050] In a specific example, the lifting unit may include a power generating unit. When the door panel 1000 is in the closed state, the power generating unit can provide driving force to switch the sealing part from the raised position to the lowered position. Similarly, when the door panel 1000 switches from the closed state to the open state, the power generating unit can also provide driving force to switch the sealing part from the lowered position to the raised position.

[0051] The aforementioned power generation unit can be a linear drive element such as a linear cylinder or linear hydraulic cylinder, so as to directly output the linear driving force required by the sealing part. Alternatively, the aforementioned power generation unit can also be a rotary drive element such as a motor. In this case, the lifting unit can also include a displacement conversion mechanism such as a gear and rack mechanism, a lead screw mechanism, or a belt mechanism, so as to convert the rotary displacement directly output by the rotary drive element into the linear displacement required by the sealing part.

[0052] In this example, the door assembly can also be equipped with a sensor, such as a limit switch or a proximity sensor, to monitor the state of the door leaf component 1000, thereby facilitating the actuation of the sealing part.

[0053] In another specific example, the lifting unit may also include a button trigger (not shown in the figure) and a transmission unit (not shown in the figure). The button trigger can be connected to the transmission unit and the sealing unit.

[0054] When the door panel 1000 is in the open state, a portion of the button trigger can be exposed. When the door panel 1000 switches from the open state to the closed state, the door stop 2000 can abut against the button trigger to retract it. The button trigger can then drive the sealing part via the transmission part, switching the sealing part to the lowered position. Conversely, when the door panel 1000 switches from the closed state to the open state, the abutting force of the door stop 2000 on the button trigger can be released, allowing the button trigger to extend automatically and thus causing the sealing part to switch to the raised position.

[0055] In this example, the door assembly does not require a dedicated power generation unit, which effectively reduces the cost of use.

[0056] It should be understood that in some other implementations of this utility model, the second sealing component 4000 may also be a fixed sealing component, that is, it may not have the ability to move in the vertical direction. In this way, the structural form of the door assembly provided by this utility model can be simpler.

[0057] In some alternative implementations, both the left stop 2200 and the right stop 2300 may be provided with corner seals 5000.

[0058] When the door panel 1000 is closed, the second sealing component 4000 can abut against the corner seal 5000. This effectively eliminates the gaps between the lower ends of the left and right sides of the door panel 1000 and the door stop component 2000, thus greatly improving the sealing and sound insulation effect of the door assembly provided in this embodiment.

[0059] like Figure 5 As shown, the corner seal 5000 may include a base plate 5100 and a sealing plate 5200. The base plate 5100 is used for mounting and fixing the corner seal 5000 to the door stop component 2000, while the sealing plate 5200 may be located on the base plate 5100. Multiple sealing plates 5200 may be arranged at intervals along the inward and outward directions. When the door component 1000 is in the closed state, sealing plates 5200 may be arranged on both the inner and outer sides of the second sealing component 4000 to accommodate the second sealing component 4000 and eliminate gaps between the second sealing component 4000 and the door stop component 2000.

[0060] In some alternative implementations, the door panel component 1000 may include an outer decorative panel layer 1100 and a sealing material layer 1200, with the sealing material layer 1200 embedded inside the outer decorative panel layer 1100. Specifically, the outer decorative panel layer 1100 may be a wood panel or similar material, and the sealing material layer 1200 can be used to improve the sound insulation performance of the door panel component 1000 itself, thereby further enhancing the sound insulation and noise reduction performance of the door assembly provided in this embodiment of the invention.

[0061] like Figure 2 As shown, the aforementioned sealing material layer 1200 may include two layers of sound-insulating panels 1210, two layers of sound-insulating felt 1220, two layers of buffer layers 1230, and one layer of sound-absorbing panel 1240. The sound-absorbing panel 1240 may be located at the midpoint in the inward / outward direction, serving as the base of the sealing material layer 1200. The buffer layer 1230 may be composed of multiple materials, such as a damping membrane, adhesive material, and substrate material. Specifically, the damping membrane may be a polyester film, which can be adhered to the substrate material using an adhesive material. The two buffer layers 1230 may be respectively disposed on the inner and outer sides of the sound-absorbing panel 1240. The two layers of sound-insulating felt 1220 may be respectively disposed on the inner and outer sides of the buffer layer 1230. The two layers of sound-insulating panels 1210 may also be respectively disposed on the inner and outer sides of the sound-insulating felt 1220. Thus, by using multiple types of sound-insulating materials in combination, the sound insulation and noise reduction performance can be significantly improved.

[0062] It should be understood that in some other implementations of this utility model, the sealing material layer 1200 may also be made using only a portion of the sound insulation board 1210, sound insulation felt 1220, buffer layer 1230 and sound absorption board 1240, which is also feasible.

[0063] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
