Description

Technical Field

[0001] This utility model relates to a thermally broken aluminum alloy garage door leaf, belonging to the field of garage door technology. Background Technology

[0002] With economic and social development, the number of family cars has gradually increased. As an auxiliary facility of the residence, the family private garage undertakes the basic function of parking vehicles. The enclosed space can prevent vehicles from being exposed to the harsh weather outdoors, thus reducing aging, and can also slow down the aging and deformation of plastic parts inside the car. The garage door is particularly important as the only entrance to the enclosed space.

[0003] Currently, most garage doors are fold-down doors, composed of multiple door panels. However, because they are mostly made of thin steel panels, they are excessively heavy, placing excessive load on key components and making them prone to wear and damage. Furthermore, thin steel panels are susceptible to corrosion due to environmental factors, easily rusting and corroding over time, compromising the overall structure and robustness, reducing load-bearing capacity, causing deformation, and shortening lifespan. Secondly, the door panels often lack internal layers and are typically hollow, one-piece molded structures. Since metal conducts heat quickly, when there is a significant temperature difference between indoors and outdoors, the metal garage door becomes a bridge for energy transfer. The temperature difference between the inside and outside cannot be completely isolated, resulting in a garage that is cold in winter and hot in summer, causing energy loss, waste, and environmental pollution. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a thermally broken aluminum alloy garage door.

[0005] The technical solution of this utility model is as follows: A fully insulated, thermally broken aluminum alloy garage door, characterized in that it includes a hollow door panel, which is composed of an A-type thermally broken aluminum alloy panel and a B-type thermally broken aluminum alloy panel connected together. The inner side of the A-type thermally broken aluminum alloy panel is provided with uniformly distributed A-type thermal insulation strip grooves, and the inner side of the B-type thermally broken aluminum alloy panel is provided with uniformly distributed B-type thermal insulation strip grooves. The A-type and B-type thermal insulation strip grooves are symmetrically arranged to form thermal insulation strip grooves, and nylon thermal insulation strips are provided inside the thermal insulation strip grooves. The cavity of the door panel is filled with polyurethane foam insulation material. The upper end of the door panel is a boss type, and the lower end of the door panel is a groove type that matches the boss type.

[0006] Furthermore, the bottom of the door panel is connected to a rubber sealing strip fixing hole, and a rubber sealing strip is provided inside the rubber sealing strip fixing hole.

[0007] Furthermore, dust covers are movably connected to both sides of the door panel.

[0008] The beneficial effects of this utility model are: This utility model solves the problems of existing flip-type garage door panels, such as the heavy weight of thin steel plates that are easy to wear, low strength and easy to deform, poor heat insulation and noise reduction effect, poor weather resistance and easy corrosion. It effectively reduces the overall weight of the garage door, effectively blocks heat conduction, isolates the temperature between the inside and outside of the door, provides heat insulation and strong wind resistance, has high strength, good sealing performance, sound insulation and noise reduction, corrosion resistance and long service life, and is energy-saving and environmentally friendly.

[0009] Firstly, this utility model consists of two thermally broken aluminum alloy panels combined to form a thermally broken insulation structure. It is lightweight and easy to assemble, resulting in less load and wear on the extension components when opening and closing the door, thus extending the garage door's lifespan. Secondly, this utility model uses a thermally broken insulation structure with nylon thermal insulation strips and polyurethane foam insulation material. The two thermally broken aluminum alloy panels are separated in the middle by filling the interior with polyurethane foam insulation material and nylon thermal insulation strips, effectively blocking heat transfer. This slows heat conduction, preventing heat from the outside from entering the door leaf and also preventing internal temperature loss. Complete temperature isolation between the inside and outside provides excellent sealing and better noise reduction, offering good sound insulation, energy saving, and environmental protection. Furthermore, it has stronger corrosion resistance, and the internal polyurethane foam filling tightly fills the interior of the door leaf, forming a unified structure. This facilitates drainage, prevents water retention and internal seepage, and ensures a robust structure with high load-bearing capacity, resistance to strong winds, and resistance to deformation, significantly extending the garage door's lifespan.

[0012] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings: like Figures 1-3As shown, a fully insulated, thermally broken aluminum alloy garage door includes a hollow door panel. The door panel is composed of an A-type thermally broken aluminum alloy panel 1 and a B-type thermally broken aluminum alloy panel 2 connected together. The inner side of the A-type thermally broken aluminum alloy panel 1 has evenly distributed A-type thermal insulation strip grooves 11, and the inner side of the B-type thermally broken aluminum alloy panel 2 has evenly distributed B-type thermal insulation strip grooves 21. The A-type thermal insulation strip grooves 11 and B-type thermal insulation strip grooves 21 are symmetrically arranged to form thermal insulation strip grooves, and nylon thermal insulation strips 3 are installed inside the thermal insulation strip grooves. The upper end of the door panel is a boss type, and the lower end of the door panel is a groove type that matches the boss type. Both sides of the A-type thermally broken aluminum alloy panel 1 and the B-type thermally broken aluminum alloy panel 2 are connected to screw fixing holes 5, and dustproof covers 7 are connected to both sides of the door panel through the screw fixing holes 5 and screws 8. The cavity of the door panel is filled with polyurethane foam insulation material 4, which hardens to form a whole, thus blocking heat conduction and providing thermal insulation. This also makes the overall door structure more robust, effectively preventing water seepage and corrosion. The polyurethane foam insulation material also has noise reduction properties, effectively isolating noise. Rubber sealing strip fixing holes 6 are connected to the bottom of the door panel, and rubber sealing strips are filled into these holes.

[0013] Multiple door panels can be combined using aluminum alloy hinges to form a complete garage door. The upper boss of one door panel fits into the lower groove of another door panel, allowing the two independently connected door panels to fit more tightly, increasing the sealing of the door panel connection, providing dustproof, windproof, and heat insulation. It also reduces friction between the door panels and lowers noise when the roller shutter door is opened and closed.

The above embodiments are merely descriptions of preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and improvements to the technical solutions of this utility model made by those skilled in the art without departing from the spirit of this utility model should fall within the protection scope defined by the claims of this utility model.
