Description

Technical Field

[0001] This utility model relates to the field of support structure technology, and in particular to a sheet metal base and a display device. Background Technology

[0002] Today, television technology has made significant progress, with its design trending towards lighter and thinner forms. Against this backdrop, the performance and design of the television stand, as a key component supporting the television and ensuring its overall balance, are receiving increasing attention.

[0003] Existing television stands are often made of plastic. However, plastic stands are gradually revealing their shortcomings in meeting the demands of modern television development. In terms of strength and stability, as televisions become thinner and lighter, screen sizes increase, internal component integration becomes more sophisticated, and weight distribution becomes more complex, placing higher demands on the load-bearing and stability capabilities of the stand. However, plastic itself has limited strength, and when subjected to the weight of the television for extended periods or potential external impacts, it is prone to deformation, affecting the normal use of the television and even posing a risk of tipping over and causing damage.

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0027] This application provides a sheet metal base and a display device, which have better reliability. The following is a detailed description with reference to the accompanying drawings.

[0028] Please see Figure 1 , Figure 1 This is a schematic diagram of the first structure of the sheet metal base provided in the embodiments of this application.

[0029] This application provides a sheet metal base 100, which is a metal structural component made of sheet material. It is primarily used to support heavy display devices such as televisions, ensuring their stability and safety. The use of metal in the sheet metal base 100 often provides users with a slim and aesthetically pleasing design, a high-end feel, and safe operation. Compared to existing bases, the sheet metal base 100 of this application has higher material utilization, better mechanical properties, and lower manufacturing costs.

[0030] The thickness of the sheet metal base 100 can be from 2mm to 10mm, for example, the thickness of the sheet metal base 100 is 5mm.

[0031] The sheet metal base 100 includes a support part 10, a torsion part 20, and a mounting part 30, which together provide stable and reliable support for heavy display devices such as televisions.

[0032] The support portion 10 extends along the first direction X in its longitudinal direction. As the main load-bearing component of the sheet metal base 100, the support portion 10 is in direct contact with the placement surface (such as a TV cabinet), bearing the entire weight of the display device and ensuring its stability. The first direction X refers to the main direction in which the support portion 10 extends in the horizontal plane, typically matching the thickness direction of the display device to maximize the support area and stability. Because the support portion 10 has a sheet-like structure, part of its contour surface is in close contact with the placement surface, providing uniform support force.

[0033] The torsion section 20 is connected to the support section 10. As a key transition area connecting the support section 10 and the mounting section 30, the torsion section 20 is formed through a specific torsion process. This design not only achieves a smooth transition from the support section 10 to the mounting section 30, but also cleverly adjusts the length extension direction of the support section 10 and the mounting section 30, facilitating support and fixation. The presence of the torsion section 20 in this application also significantly enhances the overall rigidity of the base, improves its anti-sway performance, and ensures the display device remains stable in various usage scenarios.

[0034] The mounting portion 30 is connected to the torsion portion 20. The mounting portion 30 is a part of the sheet metal base 100 used for back-locking connection with the display device, and its length extends along the second direction Y. This design allows the mounting portion 30 to flexibly adapt to display devices of different sizes and shapes, improving the versatility and compatibility of the base. Specifically, the length of the mounting portion 30 can extend away from the support portion 10 for better back-locking connection with the display device.

[0035] The intersection of the first direction X and the second direction Y forms a three-dimensional base structure, significantly improving the base's stability and anti-sway performance. For example, when the angle between the first direction X and the second direction Y is 90°, the base provides effective support and constraint in both the horizontal and vertical directions. This structural design allows the base to quickly disperse stress and maintain overall stability when subjected to external forces, effectively preventing safety hazards caused by the display device swaying. Simultaneously, the intersecting design also enhances the base's mechanical properties, improving its load-bearing capacity and lifespan, providing users with a safer and more reliable experience.

[0036] As described above, the mounting part 30 and the torsion part 20 are at an angle to each other in their length directions. This angled design allows the mounting part 30 to provide stable support for devices such as televisions in different directions, further enhancing the stability and anti-sway performance of the base.

[0037] In the sheet metal base 100, the torsion section 20 is a key transition area connecting the support section 10 and the mounting section 30. The support section 10 and the mounting section 30 often need to withstand forces in different directions. By twisting the torsion section 20 90° around its length axis, and with both ends of the torsion section 20 connected to the support section 10 and the mounting section 30 respectively, a smooth transition and directional adjustment from the support section 10 to the mounting section 30 can be cleverly achieved.

[0038] Because the torsion part 20 has a sheet-like structure, this structural characteristic allows it to be torn along its length. The sheet-like structure, while ensuring a certain strength, also possesses good flexibility and plasticity, capable of withstanding plastic deformation caused by the torsion process. The torsion part 20 has a first end face and a second end face along its length, with the second end face twisted 90° relative to the first end face about the length direction of the torsion part. The first end face connects to the support part 10, and the second end face connects to the mounting part 30, successfully changing the length extension direction of the support part 10 and the mounting part 30, allowing the entire sheet metal base 100 to better adapt to different installation and usage requirements.

[0039] Furthermore, the torsion section 20 not only achieves a change in direction, but also causes plastic deformation of the material during the torsion process, thereby increasing the rigidity and strength of the material.

[0040] Please see Figure 2 , Figure 2 This is a schematic diagram of a second structure of the sheet metal base provided in the embodiments of this application. The sheet metal base 100 also includes a raised rib structure 40, which is disposed at the connection between the torsion part 20 and the mounting part 30, and can significantly improve the rigidity and deformation resistance of the connection between the torsion part 20 and the mounting part 30.

[0041] The support part 10, the torsion part 20, and the mounting part 30 are integrally formed. During the manufacturing process of the sheet metal base 100, the support part 10, the torsion part 20, and the mounting part 30 are formed into a single integral structure in one machining operation, eliminating the need for additional assembly or connection processes. This manufacturing method improves the structural strength and stability of the base, while simplifying the production process, increasing material utilization, and reducing costs.

[0042] In some cases, the sheet metal base 100 is made of C-Mn high-strength steel, with the following chemical composition by mass percentage: C 0.1%-0.2%, Mn 0.25%-0.55%, Si ≤0.08%, S ≤0.03%, P ≤0.03%, and other individual impurities ≤0.015%. This material possesses excellent mechanical properties, with a tensile strength greater than 470 MPa, a yield strength greater than 300 MPa, and an elongation greater than 20%.

[0043] In other cases, the sheet metal base 100 can also be made of high-strength stainless steel, such as ferritic stainless steel, austenitic stainless steel, duplex stainless steel, etc.

[0044] Please see Figure 3 , Figure 3 This is a schematic diagram of a third structure of the sheet metal base provided in this application embodiment. The sheet metal base 100 also includes a folded wall portion 50, which is disposed along the width direction of the mounting portion 30 at the edge of the mounting portion 30 and extends along the thickness direction of the mounting portion 30. The folded wall portion 50 enhances the structural strength of the mounting portion 30, improves the overall stability of the sheet metal base 100, and also provides protection and limits the movement range of the device to a certain extent. The height of the folded wall portion 50 can adjust the overall anti-sway performance of the display device mounted on the sheet metal base 100.

[0045] The folding section 50 can also be integrally formed with the support section 10, the torsion section 20 and the mounting section 30.

[0046] The number of the folded wall section 50 can be one, and the folded wall section 50 and the mounting section 30 can together form an L-shaped cross section.

[0047] There are two folded wall sections 50, which are respectively arranged on both sides of the mounting section 30 along the width direction of the mounting section 30, and the two folded wall sections 50 are arranged opposite each other. The two folded wall sections 50 and the mounting section 30 can together form a U-shaped cross section.

[0048] Furthermore, this relative arrangement design facilitates the installation and positioning of display devices such as televisions. During installation, the two folding sections 50 serve as reference boundaries, enabling the display device to be quickly and accurately installed in the designated position, improving installation efficiency and precision. Simultaneously, the folding sections 50 also limit the movement range of the display device to a certain extent, preventing displacement due to accidental collisions during use and ensuring the safety of the display device.

[0049] Please continue reading. Figure 2 The mounting part 30 is provided with mounting holes 31 to achieve a secure locking connection between the base and the display device. In practical applications, the mounting holes 31 can take various forms, among which threaded holes are a common and practical type. The threaded structure on the inner wall can fit tightly with fasteners such as bolts or screws to form a reliable and durable connection.

[0050] Please continue reading for more details. Figure 2The mounting part 30 is also provided with positioning holes 32. The positioning holes 32 and mounting holes 31 are spaced apart along the length of the mounting part 30, which makes the positioning and fastening operations during installation more orderly and efficient. For example, there are three mounting holes 31 and two positioning holes 32, which are alternately arranged. The positioning holes 32 first provide precise positioning for the part to be installed 30, ensuring it is placed in the correct position, and then fastening is performed through the mounting holes 31, avoiding repeated adjustments and installation difficulties caused by inaccurate positioning. At the same time, from a mechanical performance perspective, this spaced arrangement allows the mounting part 30 to evenly bear the weight and external forces of the part to be installed 30 along its length, reducing local stress concentration and improving the overall strength and stability of the mounting part 30.

[0051] The positioning hole 32 is configured as a mounting positioning post. Specifically, a riveting process can be used at the positioning hole 32 to firmly rivet the positioning post for mounting the TV into the positioning hole 32. This process ensures a tight, non-removable connection between the positioning post and the positioning hole 32, providing high connection strength and stability. Alternatively, a screw post can be selected as the positioning post, installed in the positioning hole 32 via a threaded connection. This installation method offers the advantage of easy disassembly and replacement, meeting the needs of different usage scenarios.

[0052] Please see Figure 4 , Figure 4 for Figure 2 A magnified schematic diagram of part A. A foot pad groove 11 is provided on the side of the support part 10 away from the torsion part 20. The depth of this foot pad groove 11 is greater than 2 mm, the distance between it and the end of the side of the support part 10 away from the torsion part 20 is less than 5 mm, the distance from the side edge is in the range of 0.5 mm-1.5 mm, the groove width is 2 mm-4 mm, and the groove length is 8 mm-15 mm. For example, the foot pad groove 11 has a depth of 2.1 mm, a distance from the end of 4 mm, a distance from the side edge of 1 mm, a groove width of 3 mm, and a groove length of 10 mm.

[0053] The sheet metal base 100 also includes a pad 60, which is disposed in the foot pad groove 11. The pad 60 protrudes from the groove of the foot pad groove 11. For example, the pad 60 is attached to the foot pad groove 11 with double-sided adhesive so that the pad 60 protrudes from the foot pad groove 11 by 1.0mm-2mm, such as 1.5mm, to enhance the anti-slip and cushioning effect. The pad 60 is preferably made of rubber.

[0054] The sheet metal base 100 includes a coating applied to its outer surface to create a pleasant appearance. This coating can be a resin paint coating or a powder coating.

[0055] This application provides a display device, which can be a television, monitor, or other similar device.

[0056] The display device includes a display body and at least two sheet metal bases 100, which are the sheet metal bases 100 described in the above embodiments, and are connected to the display body. The sheet metal bases 100 are extremely thin; for example, when the display body is a 75-inch television, the thickness of the sheet metal bases 100 is less than or equal to 5mm. It is understood that the sheet metal bases 100 of this application, while maintaining sufficient reliability, also have the advantage of saving raw materials.

[0057] The sheet metal base 100 can be rationally arranged according to the shape and weight distribution of the display device, so that the center of gravity of the display device is located in the support area formed by the two sheet metal bases 100, thereby greatly improving the stability of the display device.

[0058] The sheet metal base 100 was installed on a television for performance testing. After rigorous testing, it fully met all the mechanical performance requirements of the television (details are shown in Table 1 below). Furthermore, the sheet metal base 100 is not only aesthetically pleasing but also demonstrates excellent cost control, offering a very high cost-performance advantage.

[0059] Table 1

[0060]

[0061] As can be seen, after rigorous mechanical performance testing, including no deformation or breakage under 50Kg pressure, cessation of swaying under 2kg top lateral thrust for 6 seconds, and no tipping of the TV and no breakage of the sheet metal base 100 after 50 drops from a height of 50mm, the sheet metal base 100 has been proven to have excellent performance in terms of pressure resistance, sway resistance, and drop resistance. It can stably support the TV and other display components for a long time and has good reliability.
