Technical Field
[0001] This utility model relates to the field of door and window structure technology, specifically to a soundproof wood-clad aluminum door. Background Technology
[0002] In modern living environments, noise pollution has become a significant issue affecting quality of life. Multi-source noise intrusion exhibits a dual nature: on the one hand, indoor and outdoor sources such as low-frequency traffic noise (e.g., vehicle engine resonance), high-frequency electrical appliance operation noise (e.g., air conditioner compressor vibration), and sudden noises from neighboring activities (e.g., the sound of hard-soled shoes or objects colliding) create acoustic pressure fields during nighttime rest periods, significantly reducing rest and sleep quality and potentially inducing chronic psychosomatic illnesses. On the other hand, structurally conducted noise from commercial and entertainment venues (e.g., KTV rooms) and residential functional spaces (e.g., piano practice rooms, karaoke rooms), without effective acoustic intervention, will exceed the building's sound insulation performance threshold, forming a cross-space sound pollution propagation chain, interfering with the lives and rest of nearby users, and generating or even exacerbating community conflicts. This complex noise hazard not only involves the protection of individual health rights but also poses technical challenges to the acoustic environment management of urban living spaces, urgently requiring a systematic solution through innovation in building acoustic materials and the construction of spatial sound insulation design systems.
[0003] Currently, sound insulation in furniture mainly relies on door and window structures. However, conventional thin wooden doors, due to their lightweight and low density, offer poor sound insulation. While increasing door panel thickness or filling with high-density materials (such as sound insulation cotton or damping boards) can improve sound insulation, such improvements often lead to a significant increase in door weight, affecting ease of opening and closing. Furthermore, these sound insulation methods have a diminishing return, offering limited improvement in sound insulation performance and making it difficult to strike a balance between practicality and noise reduction needs.
[0004] To improve sound insulation, some existing technologies use a metal frame combined with soundproof glass (such as double-glazed or laminated glass), leveraging the poor sound transmission properties of the material and structure (hollow) to enhance sound insulation. However, these designs typically have a strong industrial style; the cold, hard metal lines and glass materials are difficult to harmonize with the warm atmosphere of a home environment, easily creating a visual disconnect. Therefore, metal-glass soundproof doors are more suitable for commercial or office settings and cannot meet the needs of home users who require both aesthetics and practicality.
[0005] Therefore, there is an urgent need to develop a new type of soundproof door that combines the advantages of wood and metal, ensuring high sound insulation performance while also being lightweight, aesthetically pleasing, and adaptable to home environments, in order to meet users' comprehensive needs for a comfortable and quiet environment. Summary of the Invention
[0006] In response to the problems in related technologies, this utility model proposes a soundproof wood-clad aluminum door. Through innovative structural design, it ensures excellent sound insulation performance while perfectly preserving the visual beauty of natural wood, achieving an organic unity of functionality and decoration.
[0007] This utility model is implemented as follows:
[0008] A soundproof wood-clad aluminum door includes a door frame, a soundproofing component, and a wooden panel; the door frame is made of aluminum or aluminum alloy; the soundproofing component has a panel-like structure and is fixedly installed in the middle of the door frame to close the door frame; there are two wooden panels, located on the front and back of the door frame respectively; the wooden panels are fixedly connected to the door frame and cover the front and back of the door frame, as well as the soundproofing component.
[0009] Using aluminum or aluminum alloy results in a lighter overall door weight; covering the door frame and sound insulation components with wooden panels ensures structural strength and sound insulation while providing a beautiful and comfortable appearance that avoids a harsh and cold look.
[0010] As a further optimization of the above solution, the wooden panel and the door frame are glued together at the connection point.
[0011] Adhesives, glues, adhesives, and glues all refer to the same substance / concept. Specifically, they may refer to epoxy resin glue, polyurethane glue, or AB glue, etc.
[0012] As a further optimization of the above solution, the door frame is provided with at least two crossbeams; the outward side of the crossbeam has a protruding dovetail tenon; the extension direction of the dovetail tenon is the same as that of the crossbeam; the two ends of the crossbeam are respectively fixedly connected to the door frame.
[0013] The wooden panel has several horizontally extending dovetail grooves on the side facing the door frame; the dovetail grooves and the dovetail tenons cooperate with each other to fix the wooden panel to the surface of the door frame.
[0014] Specifically, the beam and door frame are fixedly connected by screws passing through them. Alternatively, the positions of the dovetail joint and dovetail tenon can be interchanged. Furthermore, the joint between the dovetail joint and dovetail tenon is coated with adhesive, such as epoxy resin adhesive or panel adhesive.
[0015] As a further optimization of the above solution, the wooden panel consists of a core, an outer frame, and trim strips; the core is a rectangular core board, the outer frame is a rectangular frame body, the outer frame surrounds the outer perimeter of the core and is spliced with the core; the trim strips include 4 strips, which are fixedly installed on the 4 edges of the core and cover the splicing area.
[0016] As a further optimization of the above solution, the outer frame and the door core form a frame-shaped groove at the splicing point, and the outer frame protrudes from the bottom of the groove;
[0017] The fastening thread has a connecting portion; on the cross-section of the fastening thread, the surface of the connecting portion is Z-shaped;
[0018] After assembly, the surface of the connecting part is simultaneously fitted and connected to the outer frame and the bottom of the groove.
[0019] As a further optimization of the above solution, the thickness of the door core is 15-19mm, the thickness of the outer frame is 10-14mm, and the thickness of the buckle wire is 21-25mm.
[0020] As a further optimization of the above solution, the sound insulation component is soundproof glass; or the sound insulation component includes a filler and a sound insulation material, wherein the sound insulation material is filled within the filler.
[0021] The soundproof glass here is either insulated glass or vacuum glass. Both consist of two layers of glass with a gap between them, forming a cavity. In the former, gas is injected into the cavity, while in the latter, air is extracted from the cavity to create negative pressure. It is also used in conjunction with laminated glass, etc.
[0022] The filling components are constructed with a galvanized steel sheet / veneer frame, and the sound insulation materials include damping sound insulation boards, sound insulation cotton, and sound-absorbing cotton.
[0023] As a further optimization of the above solution, the door frame has a hollow structure. Using a hollow structure can further reduce the weight of the metal door frame.
