Abstract
Description
Technical Field
[0001] The invention belongs to the field of shell structure technology, and specifically relates to a spliced aluminum profile shell structure. Background Technology
[0002] Currently, fierce market competition in industrial and consumer products has led to a lack of uniformity in product appearance and a relentless pursuit of cost reduction. This has resulted in a situation where products lack consistency in appearance and design, and production costs cannot be lowered. This is particularly evident in finished aluminum stretched profiles, where each product exhibits significant differences in quality. The main reason for this inconsistency is that each manufacturer creates its own molds for the appearance and shape of traditional stretched aluminum profiles, incurring high mold-making costs. These varying production costs further contribute to significant differences in finished products, making standardization impossible in product assembly, maintenance, and appearance. Additionally, some multifaceted products often operate in harsh environments, lacking maintenance year-round, and their poor dustproofing makes them susceptible to dust contamination. Summary of the Invention
[0003] The purpose of this invention is to provide a modular aluminum profile housing structure that allows for the assembly of various shapes of non-standard components, and enables adjustment of size and shape. This modular aluminum profile housing structure is easy to install and maintain. Another purpose of this invention is to provide a modular aluminum profile housing structure that improves dustproof performance and thus enhances the dustproof rating by sealing assembly gaps with three-dimensional silicone sealants.
[0004] The technical solution of this invention is a spliced aluminum profile shell structure, including a template, external corner mounting strips, and internal corner mounting strips. The template has barbs at both ends. The external corner mounting strip has two external corner template slots with perpendicular openings and one external corner screw hole. The external corner template slots have external corner hook grooves that engage with the template barbs. The internal corner mounting strip has two internal corner template slots with perpendicular openings and two internal corner screw holes. The internal corner template slots have internal corner hook grooves that engage with the template barbs. The template is spliced together by the external and internal corner mounting strips to form cavities of different sizes and shapes. Each cavity has a sealing plate at both ends. The sealing plate has through holes corresponding to the external and internal corner screw holes. The sealing plate is fixedly connected to the cavity by screws.
[0005] Preferably, the device also includes a sealing element, which includes a first sealing strip 71 that seals at the engagement position between the template and the external corner mounting strip or the internal corner mounting strip, and a second sealing strip that seals at the openings at both ends of the cavity.
[0006] Preferably, the sealing element is a one-piece molded three-dimensional silicone sealing element, and the shape of the sealing element is adapted to the shape of the cavity.
[0007] Preferably, both ends of the template are provided with sealing grooves for the insertion of the first sealing strip. The template barb engages with the external or internal corner groove to form a one-time compression on the first sealing strip inserted into the sealing groove.
[0008] Preferably, the template includes an inner decorative strip disposed on the inner wall of the template. The inner decorative strip is a T-shaped protrusion, and an inverted T-shaped groove is formed between adjacent inner decorative strips.
[0009] Preferably, the template includes an outer decorative strip disposed on the outer wall of the template. The outer decorative strip is a rectangular convex strip, and a rectangular groove is formed between adjacent outer decorative strips. The rectangular groove and the inverted T-shaped groove opposite to it form a number of segmented processing cutting positions.
[0010] Preferably, the sealing plate has a sealing strip mounting position for inserting a second sealing strip.
[0011] Preferably, the device also includes a fixing member disposed on the opposite inner sidewall of the cavity for fixing the circuit board inserted into the cavity.
[0012] Preferably, the fastener is installed in an inverted T-shaped groove on the inner wall of the template, and the fastener is provided with a groove for fixing the circuit board.
[0013] Preferably, both the external corner mounting strip and the internal corner mounting strip are cuboids with rounded chamfers.
[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0015] (1) By using templates and splicing combinations of external and internal corner mounting strips, the size and shape of the shell structure can be adjusted to meet the appearance requirements of different products, so that the appearance is uniform within a certain range. The shell structure is easy to install and maintain.
[0016] (2) One mold can be used for multiple purposes and is easy to process. Only a small number of stretching molds are needed to process various types of molds, reducing the number of molds required and thus reducing the cost of the product shell, especially for small and medium-sized products.
[0017] (3) By employing one-piece molded three-dimensional silicone seals and the installation position design of the sealing groove and sealing strip, the overall sealing of the shell structure is achieved. The three-dimensional silicone seals seal assembly gaps, improving the dustproof effect of the shell structure and thus achieving dustproof level 6 (IP6X) protection. For shells with multifaceted structures, the use of three-dimensional silicone seals can also achieve sealing of T-shaped gaps.
[0018] (4) By adopting the structural cooperation of template barbs, external corner grooves and internal corner grooves, the unique directionality of installation between template and external corner mounting strip and between template and internal corner mounting strip is ensured, and the precise cooperation between template and mounting strip in the up and down and left and right directions is ensured, effectively preventing template displacement; at the same time, the three-dimensional silicone seal is squeezed at one time to prevent the seal from being deformed due to repeated squeezing.
[0019] (5) The inner wall of the template adopts an inner decorative strip structure, which can not only form a template barb structure at both ends to realize the barb function, but also install circuit board fixing parts to facilitate the installation of circuit boards, and increase the contact area to facilitate the rapid absorption of heat emitted by internal components; the outer wall of the template adopts an outer decorative strip, which can not only improve the strength and aesthetics of the template, but also facilitate the rapid dissipation of heat from the shell.

[0039] Detailed Implementation
[0040] The present invention will now be described in further detail with reference to the accompanying drawings:
[0041] Please see Figure 1-5 , Figure 15-16 As shown, the present invention provides a splicing aluminum profile shell structure, including a template 1, a corner mounting strip 2, and a corner mounting strip 3. The template 1 has a template barb 11 at both ends. The corner mounting strip 2 has two corner template slots 21 with relatively perpendicular openings and a corner screw hole 22. The corner template slots 21 have corner hook grooves 211 that engage with the corner barbs 11. The corner mounting strip 3 has two corner template slots 31 with relatively perpendicular openings and two corner screw holes 32. The corner template slots 31 have corner hook grooves 311 that engage with the corner barbs 11. The template 1 is spliced together by the corner mounting strips 2 and 3 to form cavities 4 of different sizes and shapes. The openings at both ends of the cavity 4 are provided with sealing plates 5. The sealing plates 5 can be sheet metal sealing plates. The sealing plates 5 have through holes 51 that are opposite to the corner screw holes 22 and 32. The sealing plates 5 are fixedly connected to the cavity 4 by screws 6. The splicing aluminum profile shell structure of the present invention can adjust the size and shape of the shell structure by using the splicing combination of template 1, external corner mounting strip 2 and internal corner mounting strip 3 to meet the appearance requirements of different products.
[0042] Specifically, by splicing and combining template 1 with corner mounting strip 2, a shape is formed as follows: Figure 1 The cross-section shown is a standard rectangular shell structure; it is formed by splicing and combining template 1 with external corner mounting strip 2 and internal corner mounting strip 3, as shown. Figure 2 The cross-section shown is a T-shaped irregular shell structure, or as... Figure 3 The cross-section shown is an L-shaped irregular shell structure. It should be noted that the shell structure assembled by splicing template 1 with external corner mounting strip 2 and internal corner mounting strip 3 includes, but is not limited to, the structures listed above. Depending on the product appearance requirements, other non-standard polyhedral structures can also be assembled.
[0043] Please see Figure 8-9 As shown, the spliced aluminum profile shell structure of this invention, through the structural cooperation of template undercuts, external corner grooves, and internal corner grooves, ensures the unique directionality of installation between the template and the external corner mounting strip, and between the template and the internal corner mounting strip. The cooperation between the undercuts is based on the precision of the mold-stretched profile, with tolerances within ±0.02 mm. The precision of template segmentation using CNC equipment is far greater than that of sheet metal processing. Only high-precision processing can guarantee the sealing conditions of the shell assembly, as the cross-sectional dimension of the sealing element is only about 1.5 mm. The undercut structure cooperation can ensure the directionality of installation along the template and the internal corner mounting strip. Figure 8 The precise fit between the template in the x-direction and the external corner mounting strip 2 or internal corner mounting strip 3, as shown, and along... Figure 8 The precise fit between the template and the external corner mounting strip 2 or internal corner mounting strip 3 in the y-direction shown effectively prevents template displacement.
[0044] Please see Figure 5 , Figure 15-16 As shown, both the external corner mounting strip 2 and the internal corner mounting strip 3 are cuboids with rounded chamfers.
[0045] Please see Figure 5-7 As shown, the spliced aluminum profile shell structure also includes a sealing element 7. The sealing element 7 includes a first sealing strip 71 that seals the position where the template 1 is engaged with the external corner mounting strip 2 or the internal corner mounting strip 3, and a second sealing strip 72 that seals the openings at both ends of the cavity 4. By setting the first sealing strip 71 and the second sealing strip 72 at the assembly gap position of the shell structure, the dustproof effect of the shell structure is improved.
[0046] Furthermore, such as Figure 5 , Figure 6 , Figure 10 As shown, the seal 7 is a one-piece molded three-dimensional silicone seal, and the shape of the seal 7 is adapted to the shape of the cavity 4. For example, the cavity 4 is as follows: Figure 1 The cavity shown has a rectangular cross-section, and the seal 7 is a corresponding rectangular three-dimensional silicone seal; the cavity 4 is as follows... Figure 2The cross-section shown is a T-shaped irregular cavity, so the seal 7 is correspondingly a T-shaped three-dimensional silicone seal; the cavity 4 is as follows... Figure 3 The cross-section shown is an L-shaped irregular cavity, so the seal 7 is a corresponding L-shaped three-dimensional silicone seal. When the cavity 4 is a multi-faceted cavity of other non-standard parts, the seal 7 is also a three-dimensional silicone seal with a matching shape. By using an integrally molded three-dimensional silicone seal, the overall sealing of the shell structure is achieved. By sealing the assembly gaps with the three-dimensional silicone seal, the dustproof effect of the shell structure is improved, thereby achieving dustproof level 6 (IP6X) protection. Furthermore, for multi-faceted shell structures, the use of three-dimensional silicone seals can achieve sealing in T-shaped gaps.
[0047] Because the template 1 is connected to the external corner mounting strip 2 and the internal corner mounting strip 3 by a combination of template hooks, external corner grooves and internal corner grooves, the seal 7 is squeezed once, thereby preventing the seal 7 from being deformed due to repeated squeezing.
[0048] Please see Figure 8 , Figure 9 , Figure 11 As shown, both ends of the template 1 are provided with sealing grooves 12 for the insertion of the first sealing strip 71, so as to facilitate the installation of the first sealing strip 71.
[0049] Please see Figure 7 As shown, the sealing plate 5 is provided with a sealing plate sealing strip mounting position 52 for the second sealing strip 72 to be inserted, so as to facilitate the installation of the second sealing strip 72.
[0050] The design of the sealing groove 12 and the sealing strip mounting position 52 facilitates the installation of the sealing element 7, thereby achieving overall sealing of the shell structure.
[0051] Please see Figure 11 As shown, the template 1 includes an inner decorative strip 13 set on the inner wall of the template. The inner decorative strip 13 is a T-shaped protrusion, and an inverted T-shaped groove 131 is formed between adjacent inner decorative strips 13. The inner wall of the template adopts an inner decorative strip structure, which can not only form a template barb structure at both ends of the template to realize the barb function, but also install circuit board fixing parts to facilitate the installation of circuit boards, and increase the contact area to facilitate the rapid absorption of heat emitted by internal components.
[0052] Please see Figure 11 As shown, the template 1 includes an outer decorative strip 14 disposed on the outer wall of the template. The outer decorative strip 14 is a rectangular convex strip, and a rectangular groove 141 is formed between adjacent outer decorative strips 14. The use of an outer decorative strip on the outer wall of the template can not only improve the strength and aesthetics of the template, but also facilitate the rapid dissipation of heat from the shell.
[0053] It is worth noting that, please refer to Figure 11-14As shown, template 1 uses a standard modular template. The rectangular groove 141 and the opposite inverted T-shaped groove 131 form several segmented cutting positions 15. Cutting is performed according to these positions 15 based on product requirements, resulting in modular templates of different sizes. These dimensional variations are based on the fundamental modular standard. Assembly using external and internal corner mounting strips creates shell structures of varying sizes. This achieves multi-purpose functionality; only a small number of stretching dies are needed to process multiple template models, reducing the number of molds required and thus lowering the cost of the product shell, especially for small and medium-sized products.
[0054] Please see Figure 17-18 As shown, the spliced aluminum profile housing structure also includes a fixing member 8, which is set on the opposite inner side wall of the cavity 4 to fix the circuit board 9 inserted into the cavity 4.
[0055] Specifically, the fastener 8 is installed in the inverted T-shaped groove 131 on the inner wall of the template, and the fastener 8 is provided with a groove 81 for fixing the circuit board. Please refer to Figure 2-3 As shown, multiple fasteners 8 can be installed at different positions on the inner wall of the cavity 4 according to the different shapes of the product and the installation requirements of the circuit board or components, so as to facilitate the installation of circuit boards or components at different positions in the cavity 4.
