Description

Metal spliced display frame and strong display made of the same

The present invention is related to the field of display frames, and in particular to a metal spliced display frame which can facilitate the manufacturing process, has a consistent horizontal position of the entire frame, and has a stable structure, and a strong display made using the same.

In the prior art, a display frame refers to a frame structure used to fix and protect display components. Traditional display frames are usually made of metal or plastic materials and have a simple rectangular or square shape. However, these traditional frames have some limitations in functionality and design.

In experience, the manufacture of the display frame is implemented by hollowing out metal parts or using multiple brackets to weld into shape. However, these methods have some disadvantages. First, hollowing out metal parts is not economical in terms of manufacturing cost, and the method of welding multiple brackets is prone to the problem of inconsistent overall horizontal position. Especially in large-sized or special-specification displays, such as long-shaped touch display devices for customer use, it is even more difficult to achieve a flat state for the entire frame. Once the frame cannot be flat, it is easy to apply additional stress to the display module during assembly, causing the risk of damage to the display. All of the above factors lead to the risk that the stability of the display may be relatively poor under long-term use.

To overcome these problems, there is another technology that uses single-module injection molding to manufacture the entire display frame structure in one molding. This method not only reduces manufacturing costs, but also ensures that the overall horizontal position of the frame is consistent, thereby improving the stability and reliability of the display.

However, the single-module injection molding method may face the problem of insufficient material strength. The strength of the commonly used plastic materials is relatively low and cannot be compared with the traditional metal frame. This may cause the frame to be easily deformed or damaged when facing strong external impact, and cannot provide sufficient protection. To solve this problem, some previous technologies have proposed methods of using reinforced fibers or adding metal support structures to enhance the strength and rigidity of the frame. This structural design attempts to provide higher impact resistance and deformation resistance, thereby improving the protection performance of the display frame.

However, it should be noted that when designing a monitor frame, it is necessary to balance material selection, cost, and performance requirements, and choosing a higher-strength material or adding a reinforcement structure may increase manufacturing costs. In addition, the method of combining the use of reinforced fibers or adding metal support structures may also cause the overall frame to be uneven after the process due to the rigidity of the material. That is, with the application of reinforced fibers or metal support structures, the frame may be deformed or uneven in height due to welding during the manufacturing process. This may cause the frame to appear slightly concave or uneven in appearance, which not only affects the visual beauty of the monitor, but may also damage the various layers of components or panels of the display module due to pulling during or after assembly.

Therefore, in view of the defects in the manufacturing process and structure of the existing display frame, the present invention proposes a metal splicing display frame, hoping to take into account the convenience of assembly, reduce costs, high stability, and excellent overall flatness of the frame to facilitate installation around the display, so as to use the frame to manufacture a strong display with better quality.

One of the purposes of the present invention is to provide a metal frame for a display that has low manufacturing cost, convenient assembly, enhanced stability, and extremely high overall flatness. In particular, when facing a large-size display, the present invention can effectively maintain the entire frame at the same level, thereby improving the previous method of directly pressing metal materials and then hollowing out a part of the area, which has a high manufacturing cost, or using multiple separate brackets to weld and form a frame, which makes it difficult to keep the entire frame at the same level, resulting in the inability to effectively implement installation or even the stress caused by the tilt of the frame during assembly, which damages the display module or panel.

In order to enable a person with ordinary knowledge in the field to clearly understand the content of the present invention, the following description is provided with drawings for your reference.

Please refer to Figures 1 to 4B, which are a schematic diagram of a three-dimensional exploded view of a metal spliced display frame, a schematic diagram of a first side bar structure, a schematic diagram of a second side bar structure, and schematic diagrams (I) and (II) of assembling a metal spliced display frame of a first embodiment of the present invention. The present invention provides a metal spliced display frame 1, comprising two first side bars 11, two second side bars 12, and a plurality of nails 13.

The first side strips 11 are long strip structures and include a rectangular solid body 111 and at least one flange 112 extending from the side edge of the rectangular solid body. Two splicing recesses 1111 are formed at opposite ends of the rectangular solid body 111, wherein the two splicing recesses 1111 at the same end are symmetrical to each other, and the splicing recesses 1111 are formed by the long sides of two opposite assembly surfaces 1112 of the rectangular solid body 111 being recessed inwardly, respectively. The splicing recesses 1111 of the rectangular solid body 111 are located on the same side and are defined as a splicing side 113, and the other end side relative to the splicing side 113 is defined as a frame side 114. The edge of the frame side 114 of the rectangular solid bodies 111 extends along the normal direction of the assembly surfaces 1112 to form the flange 112, and at least one first locking hole 1113 is formed in the splicing recesses 1111 along the normal direction of the assembly surfaces 1112.

The second side bars 12 are respectively a long flat plate 121 and have two assembly sections 122 arranged perpendicular to the long flat plate 121. The second side bars 12 are respectively spliced perpendicularly to the ends of the first side bars 11 to form a square frame in which the two first side bars 11 are parallel to each other and the two second side bars 12 are parallel to each other. The width of the long flat plate 121 is consistent with the width of the rectangular solid body 111 plus the flange 112. The two ends of the two assembly sections 122 are respectively provided with at least one second locking hole 1221 for corresponding embedding in the two splicing recesses 1111. After the first side bars 11 and the second side bars 12 are embedded in each other, the assembly surfaces 1112 of the rectangular solid body 111 and the outer surfaces of the assembly sections 122 are located in the same plane. Here, the assembly sections 122 and the long flat plate 121 are set to be equal in length. The locking nails 13 are respectively passed through the second locking holes 1221 and the first locking holes 1113 in sequence to fix the first side strips 11 and the second side strips 12 to each other.

Accordingly, through the special corresponding structural design of the first side bars 11 and the second side bars 12, the first side bars 11 and the second side bars 12 can form a very stable and highly flat frame after assembly, and at the same time, it is very easy to assemble, thereby effectively improving the defects of the existing process technology such as high manufacturing cost or difficulty in maintaining the frame at the same level after manufacturing. Specifically, since the first side bars 11 and the second side bars 12 are all metal components that are not bent separately, it can effectively avoid the phenomenon of inconsistent frame levelness caused by structural skewness during bending processing and subsequent assembly. In addition, the structural design of the splicing recesses 1111 of the first side bars 11 can facilitate the assembly with the second side bars 12, and the advantages of being quick and convenient and easy to manufacture. At the same time, due to the structural correspondence design of the first side bars 11 and the second side bars 12, the assembly surfaces 1112 of the rectangular solid bodies 111 and the outer surfaces of the assembly segments 122 are located on the same plane after assembly, so that the excellent flatness is achieved without the frame being skewed. In particular, when it is subsequently combined with a touch display panel to be used as a variety of medium-sized or special-sized touch display products for public use, the various advantages of the metal splicing display frame 1 are further highlighted.

Preferably, the second side strips 12 can be processed according to the requirements, for example, the joint of the frame side 114 where the first side strips 11 and the second side strips 12 are assembled is processed into an arc segment to meet the appearance requirements or the subsequent installation application requirements of the display.

Furthermore, considering the structural rigidity and overall surface flatness of the metal splicing display frame 1, the joint of the frame side 114 assembled by the first side bars 11 and the second side bars 12 can be made flatter by welding or brazing. By welding or brazing, the joint of the frame side 114 assembled by the first side bars 11 and the second side bars 12 can be better joined and formed into a seamless and smooth state, and has excellent structural firmness, and is relatively simple and convenient in operation.

In this embodiment, the flanges 112 are located on opposite sides of the metal splicing display frame 1, and as shown in Figures 4A and 4B, the flanges 112 of the metal splicing display frame 1 are matched with the assembly surfaces 1112 and the outer surfaces of the assembly sections 122 on the same plane to form a concave structure, which can have a accommodating function to facilitate the subsequent assembly of display components. Of course, the flanges 112 can also be formed on one side of the metal splicing display frame 1. The side of the metal splicing display frame 1 shown in Figure 4B can be used to fix the back panel after assembling the display panel or module. A better application method is to open lock holes on the first side bars 11 and the second side bars 12, and then cover and lock the back panel to allow the display panel or module to be stably set in the metal splicing display frame 1.

Please continue to refer to Figure 5, which is a schematic diagram of the assembly of a metal splicing display frame of another embodiment of the present invention. In this embodiment, the first side bars 11 each have a leveling slope 115, and the leveling slope 115 is located at the joint of the frame side 114 where the first side bars 11 and the second side bars 12 are assembled, so that the outer surface of the first side bars 11 and the second side bars 12 after assembly forms a V groove 14 for filler leveling and uniform painting. In order to facilitate the subsequent painting process at the joints of the first side strips 11 and the second side strips 12 after being assembled, and to prevent the paint from falling off or cracking at the joints so as to maintain a long-term appearance, the first side strips 11 can be provided with the leveling bevel 115. The V-groove 14 structure can be formed by the leveling bevel 115 after the first side strips 11 and the second side strips 12 are spliced together, and before painting, the V-groove 14 structure can be filled with filler and then leveling processes such as grinding can be performed to fill the joints before the painting process can be performed. Since the V-groove 14 structure has been leveled by the filler, the metal splicing display frame 1 forms a smooth and seamless outer surface, so the paint can be firmly and evenly attached to the metal splicing display frame 1 without peeling off.

Please refer to Figures 6 to 7B, which are the three-dimensional exploded schematic diagrams and assembly schematic diagrams (I) and (II) of the metal splicing display frame of the second embodiment of the present invention. Based on the same technical concept, another metal splicing display frame 2 is disclosed in this embodiment, including: four corner pieces 21, four third side strips 22 and a plurality of nails 23.

The equal corner pieces 21 respectively include a solid body 211 and at least one flange 212 extending from the side edge of the solid body 211. The two end side surfaces of the solid bodies 211 are perpendicular to each other and two splicing recesses 2111 are formed thereon respectively, wherein the two splicing recesses 2111 at the same end are symmetrical to each other, and the splicing recesses 2111 are formed by two opposite assembly surfaces 2112 of the solid bodies 211 being recessed inwardly respectively, and the end sides of the solid bodies 211 where the splicing recesses 2111 are located are defined as two splicing sides 213, and the other end sides relative to the splicing sides 213 are defined as a frame side 214. The edge of the frame side 214 of the solid bodies 211 extends along the normal direction of the assembly surfaces 2112 to form the flange 212, and at least one first locking hole 2113 is formed in the splicing recesses 2111 along the normal direction of the assembly surfaces 2112.

The third side bars 22 are respectively a long flat plate 221 and have two assembly sections 222 arranged perpendicular to the long flat plate 221. The ends of the third side bars 22 are respectively spliced with the corner pieces 21 to form a square frame with the corner pieces 21 as four end points and the third side bars 22 as four sides. The width of the long flat plate 221 is consistent with the width of the solid bodies 211 plus the flange 212. The two ends of the assembly sections 222 are respectively provided with at least one third locking hole 2221 for corresponding embedding in the splicing recesses 2111. After the corner pieces 21 and the third side bars 22 are mutually embedded, the assembly surfaces 2112 of the solid bodies 211 and the outer surfaces of the assembly sections 222 are located in the same plane. The locking nails 23 are respectively and sequentially penetrated through the third locking hole 2221 and the first locking hole 2113 to fix the equal corner pieces 21 and the third side strips 22 to each other.

The metal splicing display frame 2 formed by such splicing has excellent structural stability and strength, and also has the advantages of fast and convenient manufacturing in assembly. Specifically, each component of the metal splicing display frame 2 is a non-bent metal part, so that the problem of structural skewness caused by metal bending can be avoided. In addition, due to the special splicing recess structure of the equal corner pieces 21, and the third side strips 22 having the long flat plate 221 and the assembly segments 222 structure, the third side strips 22 can be assembled with the equal corner pieces 21 to form a mutually embedded assembly state, and there is no need to go through complicated alignment or fixing processes in the assembly. As described above, the splicing recesses 2111 and the ends of the third side strips 22 need only be embedded with each other to form a square frame, which has a considerable manufacturing convenience advantage. Therefore, the metal spliced display frame 2 has an excellent structural flatness compared to the previous frames, and also has the advantages of lower production cost and convenient assembly.

The assembled metal splicing display frame 2 is as shown in Figures 7A and 7B. In this embodiment, the flanges 212 are located on both sides of the corner pieces 21, so the metal splicing display frame 2 has concave structures formed on both sides, as shown in Figures 7A and 7B. The advantages and details of forming the concave structure with the flanges 212 and the outer surfaces of the assembly surfaces 2112 and the assembly sections 222 that are in the same plane have been described above. Please refer to the above content again, and it will not be repeated here.

Similarly, the joints of the frame side 214 assembled by the equal corner pieces 21 and the third side strips 22 of the metal splicing display frame 2 of this embodiment can also be flattened by welding or brazing to enhance the strength and stability of the overall structure after assembly, and the operation is relatively simple. In addition, the joints of the frame side 214 of the equal corner pieces 21 of this embodiment can be processed into arc segments. The other more detailed technical features and corresponding functional descriptions have been mentioned in the previous paragraphs, please refer to the aforementioned content again, and will not be repeated here.

Please continue to refer to Figures 8, 9, 10 and 11, which are a three-dimensional exploded schematic diagram of a metal spliced display frame of the third embodiment of the present invention, a metal spliced display frame assembly schematic diagram, and a three-dimensional exploded schematic diagram and an assembly schematic diagram of a metal spliced display frame of another embodiment. Based on the same technical concept, the present invention further discloses a metal spliced display frame 3, including four corner pieces 31, four third side strips 32 and a plurality of nails 33.

The equal-corner piece 31 also includes a solid body 311, and the two end side surfaces of the solid body 311 are perpendicular to each other and extend two engaging sections 316 respectively. The engaging sections 316 respectively form two splicing recesses 3111, wherein the two splicing recesses 3111 at the same end are symmetrical to each other, and the positions of the splicing recesses 3111 are defined as two splicing sides 313, and the other end sides relative to the splicing sides 313 are defined as a frame side 314, wherein the end edges of the frame sides 314 of the solid bodies 311 extend along the normal direction of the two assembly surfaces 3112 to form at least one flange 312, and at least one first locking hole 3113 is further formed in the splicing recesses 3111 along the normal direction of the assembly surfaces 3112.

The third side bars 32 are respectively a long flat plate 321 and have two assembly sections 322 arranged perpendicular to the long flat plate 321. The ends of the third side bars 32 are respectively spliced with the corner pieces 31 to form a square frame with the corner pieces 31 as four end points and the third side bars 32 as four sides. The width of the long flat plate 321 is consistent with the width of the solid bodies 311 plus the flange 312. The two ends of the assembly sections 322 are respectively provided with at least one third locking hole 3221 for corresponding embedding in the splicing recesses 3111. After the corner pieces 31 and the third side bars 32 are mutually embedded, the assembly surfaces 3112 of the solid bodies 311 and the outer surfaces of the assembly sections 322 are located in the same plane. The locking screws 33 are respectively inserted through the third locking hole 3221 and the first locking hole 3113 in sequence to fix the corner pieces 31 and the third sides 32 to each other. Among them, Figures 8 and 9 illustrate one structural state of the metal splicing display frame 3, showing that the assembly segments 322 and the long flat plate 321 are not equal in length, and Figures 10 and 11 are another structural state of the metal splicing display frame 3, showing that the assembly segments 322 and the long flat plate 321 are equal in length.

Accordingly, the metal splicing display frame 3 also has excellent structural stability, strength and structural flatness, and also has the advantages of fast and convenient manufacturing and low manufacturing cost in assembly. Other additional technical features such as the arrangement of arc segments or the joints can be further straightened by welding or rivet welding and their more detailed functional descriptions have been described in the previous embodiment, please refer to the aforementioned content again, and will not be repeated here.

Further, please refer to FIG. 12, which is a schematic diagram of the assembly of a metal splicing display frame of another embodiment of the third embodiment. In this embodiment, the equal corner piece 31 has two leveling inclined surfaces 315, and the leveling inclined surfaces 315 are located at the joint of the equal corner piece 31 and the third side strips 32 assembled with the frame side 314, so that the outer surface of the equal corner piece 31 and the third side strips 32 after assembly forms a V groove 34 for filler leveling and uniform painting process. This can enhance the stability of the painting after assembly. By utilizing the V-groove 34 structure formed by the leveling slopes 315 after assembly, the joints of the metal spliced display frame 3 can be eliminated through the filling and leveling process. The subsequent painting can also have better paint adhesion and the paint is less likely to peel off and crack.

Please continue to refer to Figures 1 to 4B and 13, wherein Figure 11 is a schematic diagram of the structure of a rugged display made based on the first embodiment of the present invention. Based on the metal splicing display frame structure of the above-mentioned embodiments, the present invention further discloses a rugged display 9, comprising a metal splicing display frame 1 and a liquid crystal module 90. The metal splicing display frame 1 is selected from the aforementioned metal splicing display frame 1 mainly formed by splicing the first side bars 11 and the second side bars 12, or the metal splicing display frame mainly formed by splicing the corner pieces and the third side bars. In this embodiment, the metal splicing display frame 1 formed by splicing the first side bars 11 and the second side bars 12 is used as an example. The liquid crystal module 90 is provided to be accommodated in the metal splicing display frame 1 .

Accordingly, based on the advantages of the metal splicing display frame, such as low manufacturing cost, easy assembly, extremely high structural stability and overall flatness, the rugged display 9 can be effectively installed when installing the liquid crystal module 90, and the stress caused by the tilt of the frame during installation is avoided from damaging the liquid crystal module 90, thereby forming a display product with excellent structural stability. Preferably, the rugged display 9 can be a display with a touch function applied to industrial computers, for example.

Furthermore, in order to meet the subsequent application and installation requirements of the display product, the four corners of the metal spliced display frame 1 can also be processed into an arc segment 19, so that the four corners form an arc shape.

In summary, the metal splicing display frame of the present invention and the strong display made of the same are formed by assembling, so the manufacturing process is extremely convenient. In addition, since the single components are all components that do not need additional bending, each component is located at the same horizontal position and will not produce unevenness caused by bending after assembly. In addition, the splicing method proposed by the present invention greatly improves its combination stability and strength, and also has the additional effect of leveling the surface of the joint and then painting it to maintain a long-term appearance.
