Abstract
Description
Structure of aluminum extrusion Technical Field
[0001] This invention provides an aluminum extrusion structure that can improve structural strength, facilitate processing, and reduce manufacturing costs. Prior Technology
[0002] Note that aluminum extrusion structures are widely used in the manufacture of glass door frames due to their advantages such as light weight, good processability, and neat appearance. In general applications, aluminum extrusion mainly serves as the frame support structure for glass doors, positioning and fixing the glass through its frame structure, providing basic stability and safety. However, when the aluminum extrusion structure needs to further support components such as hinges, dampers, or other additional hardware, the material strength and rigidity of aluminum are lower than those of iron or steel. Under prolonged load or repeated opening and closing operations, it is prone to local deformation, structural fatigue, or even cracking, which affects the overall stability of the door. In severe cases, it may even cause the door or additional components to detach, raising safety concerns.
[0003] In view of this, conventional technology involves adjusting the cross-sectional structure design of aluminum extrusion, such as designing the wall thickness of the frame to be uneven, especially increasing the material thickness in areas that need to withstand greater stress, in order to improve the local structural strength and load-bearing capacity. While this method can improve the shortcomings of aluminum extrusion in bearing heavy objects to some extent and expand its application range, such designs also lead to processing limitations and cost issues. Specifically, when the wall thickness of the aluminum extrusion increases, the traditional rapid forming method using stamping in the thick-walled area can easily cause deformation in the thin-walled area. This often necessitates the use of numerically controlled machining (CNC) equipment for cutting or drilling, which not only prolongs processing time but also increases equipment and process costs, reducing overall production efficiency.
[0004] Therefore, how to solve the aforementioned balance problem and deficiency between structural strength and processing convenience is the direction that the applicant of this new invention and related manufacturers in this industry urgently want to study and improve. Summary of the Invention
[0005] Therefore, in view of the above-mentioned deficiencies, the applicant of this new invention collected relevant information, conducted multiple evaluations and considerations, and, based on years of experience accumulated in this industry, through continuous trial and modification, designed this new patent holder for an aluminum extrusion structure that can improve structural strength, take into account processing convenience, and reduce manufacturing costs.
[0006] The purpose of this invention is to utilize the design that the thickness of the thin-walled part is less than that of the first load-bearing part, so that the thin-walled part can be used as a stress adjustment area during the hole-making process, thereby reducing the stamping load and suppressing the transmission of processing stress to the closing part, thus avoiding deformation or damage to the closing part.
[0007] Another objective of this invention is to improve torsional strength and reduce stress concentration by utilizing the design of the first load-bearing part, the second load-bearing part, the decorative part, and the closing part, so that the whole structure has structural strength, ease of processing, and stability in use.
[0008] To achieve the above objectives, the structure of this novel component includes: a main body and a mounting portion. The main body includes a first load-bearing portion, a thin-walled portion, a second load-bearing portion, a decorative portion, and a closing portion. The first load-bearing portion supports a hinge. The thin-walled portion is located on the first load-bearing portion. The second load-bearing portion extends from one end of the first load-bearing portion, and the thickness of the first load-bearing portion is greater than the thickness of the second load-bearing portion, while the thickness of the second load-bearing portion is greater than or equal to that of the thin-walled portion. The decorative portion extends from one end of the second load-bearing portion. The two ends of the closing portion are respectively connected to the decorative portion and the side of the first load-bearing portion opposite to the second load-bearing portion. The mounting portion is located on one side of the main body and is used to install a door or window component.
[0009] In this design, the hinge is first positioned on one side of the main body and secured by a first load-bearing section. This allows the force on the hinge to be preferentially transferred to the first load-bearing section to withstand the weight and recurring stress generated when the door opens and closes, thereby improving the overall structural stability and durability. Then, a second load-bearing section extends from the first, gradually distributing the load-bearing capacity from the main stress area to other sections. This maintains necessary strength while reducing material usage, achieving both structural support and lightweighting. By controlling the thickness of the second load-bearing section to be between that of the first load-bearing section and the thin-walled section, the thin-walled section can be used as a specific stress adjustment area when machining the openings required for the hinge pivot. This reduces the required force during stamping and suppresses the transmission of processing stress to the closing part and other structures, thus preventing deformation or damage to adjacent structures and ensuring the integrity of the overall structure. Furthermore, the decorative section extends from the second load-bearing section, providing not only aesthetic enhancement but also serving as a structural extension to improve overall visual integrity. The closure section connects the decorative section to the back of the first load-bearing section, forming a closed structure. This not only improves the torsional strength and structural stability of the components but also helps to disperse external forces and reduce localized stress concentration. Finally, the installation section houses door and window components, allowing the main body to be integrated with the door and window structure, achieving a balance of structural support, load-bearing enhancement, and ease of fabrication.
[0010] By using the above technology, we can overcome the problems of insufficient load-bearing strength, local thickening leading to processing difficulties, and increased processing costs in conventional aluminum extrusion structures, and achieve the practical progress with the aforementioned advantages.

[0012] To achieve the above objectives and effects, the technical means and structure adopted by this invention are described in detail below with reference to the preferred embodiment of this invention, so as to facilitate a complete understanding.
[0013] Please refer to Figures 1-6, which are perspective views of the first embodiment of this invention and schematic diagrams of the hinge connection. The figures clearly show that this invention includes:
[0014] Please refer to Figures 1 and 2. A main body 1 includes: a first load-bearing portion 11 for supporting a hinge 4, and the first load-bearing portion 11 having a thin-walled portion 111; a second load-bearing portion 12 extending from one end of the first load-bearing portion 11, and the thickness of the first load-bearing portion 11 being greater than the thickness of the second load-bearing portion 12, and the thickness of the second load-bearing portion 12 being greater than or equal to the thickness of the thin-walled portion 111; a decorative portion 13 extending from one end of the second load-bearing portion 12; and a closing portion 14, with its two ends respectively connected to the decorative portion 13 and the side of the first load-bearing portion 11 opposite to the second load-bearing portion 12; and
[0015] An installation part 2 is provided on one side of the main body 1 for installing a door or window component 5.
[0016] The main body 1 is a rod made of aluminum extrusion technology; the first load-bearing part 11, the second load-bearing part 12, the decorative part 13, and the closing part 14 are the four surrounding and enclosing sides of the main body 1. The thickness of the first load-bearing part 11 is approximately 2.7 mm, the thickness of the second load-bearing part 12 is approximately 1.5 mm, the thickness of the decorative part 13 and the closing part 14 is approximately 1.2 mm, and the thickness of the thin-walled part 111 is approximately 1.4 mm; the mounting part 2 has an L-shaped structure. However, the corresponding forms of the above-mentioned components are only examples of preferred embodiments. Any form with the same function falls within the scope of this invention and is not limited to the above examples.
[0017] The above explanation has provided an understanding of the structure of this technology. Based on the corresponding fit of this structure, advantages such as improved structural strength, ease of processing, and reduced manufacturing costs can be achieved. As clearly shown in the figures, in practical application, the main body 1 is first fixed to the wall or door frame, and a door hinge 4 is installed on one side. Through locking, the weight of the door hinge 4 and the force generated during opening and closing are concentrated on the first load-bearing part 11 of the main load-bearing area, ensuring stable support even after long-term use. When the door is opened or closed, due to the relationship between the force direction and the rotation axis, the second load-bearing part 12 in the adjacent area can simultaneously share part of the load, expanding the overall force distribution from a single area to multiple areas. Therefore, the thickness of the second load-bearing part 12 is designed to be greater than the thickness of the decorative part 13 and the closing part 14, effectively reducing local stress concentration and extending service life.
[0018] Please refer to Figure 3. During the processing stage, when it is necessary to set the pivot structure of the hinge 4 for hole opening, the first load-bearing part 11 should be selected. However, the thickness difference of the closing part 14 adjacent to the first load-bearing part 11 is large. Under normal circumstances, the closing part 14 is prone to deformation or wear. In this case, through the design of the thin-walled part 111, the thin-walled part 111 forms a force adjustment area on the first load-bearing part 11. Specifically, since the thin-walled part 111 is defined at the junction of the first load-bearing part 11 and the closing part 14, and the thickness of the thin-walled part 111 is thinner than that of the first load-bearing part 11, the force required during the stamping process can be effectively reduced when the stamping process is performed on the first load-bearing part 11. In this way, in addition to avoiding the processing difficulties caused by the large thickness of the main load-bearing area, it can also suppress the transmission of stress generated during the processing to other structures. In particular, it can prevent the closed part 14 near the wall from deforming, bending or even breaking due to stress, and ensure that the overall structure maintains good shape and strength before and after processing.
[0019] Furthermore, the decorative part 13 of the outer structure faces outward after assembly, simultaneously concealing the internal structure and enhancing the overall appearance. The closing part 14 near the wall, once connected, creates a closed structure, effectively improving torsional and deformation resistance during repeated opening and closing or under external force, and further dispersing stress to prevent localized damage. Thus, the main body 1 achieves improved overall reliability while balancing load-bearing capacity, ease of processing, and aesthetic quality.
[0020] In one embodiment, the first load-bearing part 11, the second load-bearing part 12, the decorative part 13, and the closing part 14 surround to form an accommodating space 15. The hinge 4 is disposed within the accommodating space 15, meaning that the body part 1 is hollow. This not only saves on the material cost required to manufacture the body part 1, but also ensures the overall structural strength due to the special design of the wall thickness on all four sides of the body part 1. Furthermore, it can accommodate part of the hinge 4 internally, which is beneficial to the aesthetic appearance of the external shape.
[0021] In one embodiment, referring to Figure 4, the first load-bearing part 11 has a fixing groove 112 on one side. When there are multiple body parts 1, the two ends of a connecting member 3 are disposed in the fixing groove 112 of each body part 1 for pairwise docking and fixing. The fixing groove 112 is formed on one side of the first load-bearing part 11 by a rib-like structure protruding from the inner sidewall of the second load-bearing part 12 and the closing part 14. When the user wants to splice multiple body parts 1 together to form a frame, the docking end faces of the body parts 1 are beveled, and the two ends of the L-shaped connecting member 3 are respectively inserted into the fixing groove 112 of each body part 1. Finally, the beveled surfaces of the two body parts 1 are brought together to lock the connecting member 3 from the first load-bearing part 11, thus completing the fixing of the two body parts 1.
[0022] In one embodiment, referring to Figure 5, a clearance portion 1121 is further provided on the fixing groove 112, and a positioning portion 1122 is provided on one side of the fixing groove 112. The clearance portion 1121 is a space that allows the connector 3 to move buffered after locking, and the positioning portion 1122 is a narrow groove after the side wall of the fixing groove 112 is recessed, so that the positioning portion 1122 conforms to the width of the connector 3. In practical design, in order to accommodate the narrower width of the standard connector 3, a stepped structure is formed in the fixing groove 112, wherein the positioning portion 1122 serves as the narrower first step, used to position the connector 3 in the width direction, so that it can be quickly aligned and maintain a stable position when inserted; during the screw locking process, the connector 3 is driven by the locking force to move closer to the first load-bearing portion 11, so that it is attached and positioned and fixed. At the same time, the wider second step in the stepped structure and part of the space of the original insertion area form an open area (clearance portion 1121). Therefore, during subsequent disassembly operations, the connecting part 3 can generate appropriate displacement and buffer stroke within the clearance portion 1121, avoiding jamming or difficulty in removal due to insufficient space, thereby improving the convenience of disassembly and assembly and reducing the difficulty of maintenance.
[0023] Please also refer to Figures 7-8, which are front views and usage diagrams of the second embodiment of this invention. As can be clearly seen from the figures, this embodiment is largely the same as the previous embodiment, except that it has a gripping part 21 on one side of the mounting part 2. The gripping part 21 is a J-shaped structure, which uses the curved part to facilitate the user's grip for pushing, pulling, opening and closing the door.
[0024] However, the above description is only a preferred embodiment of the present invention and does not limit the scope of the patent of the present invention. Therefore, any simple modifications and equivalent structural changes made using the contents of the present invention's specification and drawings should also be included within the scope of the patent of the present invention and are hereby stated.
