Description

Technical Field

[0001] This invention generally relates to a display device and its back cover, and more specifically, to a display device and its back cover having a beveled stud structure. Background Technology

[0002] Display technology is now widely used in various electronic products to display necessary information and images. Among various display technologies, curved display technology is gradually being applied to various medium and large display products because it maintains a uniform viewing distance from different angles, making it more comfortable for users to view the screen.

[0003] Curved display devices present greater challenges when mounting various brackets on their back surfaces due to the curved arc angles. This is especially true when mounting them onto a system frame where locking is required, as the curved back cover contains both vertical and inclined surfaces with varying angles. When studs are used for riveting on the curved back cover, the presence of studs at different angles necessitates a separate riveting mold for each stud at a particular angle within a given area. Managing studs at different angles is difficult, increasing mold adjustment time, reducing production capacity, and consequently increasing manufacturing costs. Therefore, finding a solution to adjust studs at different angles on the inclined surfaces, making them as easy to install as those on the vertical surfaces, and thus reducing manufacturing costs, has become a pressing issue for those skilled in the art. Summary of the Invention

[0004] One object of the present invention is to provide a display device and its back cover, which allows adjustment of studs at different angles on the inclined surface of the curved back cover, adjusting the studs at different angles to approximately the same angle as the studs on the vertical surface. Therefore, manufacturing the curved display device and its curved back cover is easier, and manufacturing costs are relatively reduced.

The orientation or orientation of the elements in the device in the drawings is not limited by the rotation of the device. The directions of the D1, D2, and D3 axes in the drawings intersect each other perpendicularly, for example, they are the X, Y, and Z axes of a Cartesian coordinate system, but their correspondence is not limited.

[0094] Figure 1 This is a side view of a display device according to an embodiment of the present invention. Figure 2 This is a schematic diagram of the rear structure of a display device according to an embodiment of the present invention. Please refer to... Figure 1 and Figure 2 The display device 10 of the present invention includes at least a display module 100 and a back cover 200. The display device 10 can be as follows: Figure 1 and Figure 2 The vertical arrangement shown can also be horizontal (not shown), and the arrangement method is not limited. The display module 100 of the display device 10 can be, for example, a curved liquid crystal display module, a curved light-emitting diode display module, a curved organic light-emitting diode display module, a curved quantum dot light-emitting diode display module, a curved micro light-emitting diode display module, or various other curved display modules, but is not limited to these. The curved display modules of the various curved display devices described above are well known to those skilled in the art, and therefore will not be described in detail.

[0095] Please refer to Figure 1 and Figure 2 The display module 100 has a display surface 102 and a back surface 104. The display surface 102 is used to display various required information or images, and the display surface 102 has a curved arc corresponding to the display module 100, making it more comfortable for users to view the display device 10. The curvature angle of the display module 100 can be designed according to product requirements. On the back surface 104 of the display module 100, the back shell 200 is assembled to the back surface 104 of the display module 100 using various methods such as locking and snap-fit, for the purpose of protecting the display module 100. At the same time, various assembly structures can also be designed on the back shell 200, such as riveting studs, so that it can be assembled with various different brackets or other fixing devices, so that the display device 10 can be hung on the wall or various signs. In a variation embodiment, the display module 100 and the back shell 200 of the present invention can also be replaced by a slanted display module and a slanted back shell for special product requirements, and assembled to form a slanted display device, which is well known to those skilled in the art, and therefore will not be described in detail.

[0096] Please refer to Figure 1 and Figure 2 The back cover 200 includes at least a housing 201 and a beveled stud structure 400. The housing 201 may have a vertical surface area 202 and one or more beveled areas 204, depending on the product design. In this embodiment, for example, it is illustrated by a partition line 203 that roughly divides the lower vertical surface area 202 and the upper beveled area 204. Alternatively, in other embodiments, the vertical surface area 202 is a completely flat design (no slope change), while the beveled area 204 includes one or more slopes (with slope changes), and the partition line 203 is located at the starting point of the slope change between the vertical surface area 202 and the beveled area 204. Therefore, the beveled area 204 may include a beveled surface with a slope change or multiple curved surfaces with slope changes. In more varied embodiments, the vertical surface area 202 is located, for example, in the center. Above and below the vertical surface area 202, respective partition lines 203 and inclined surface areas 204 (not shown) are provided to achieve a uniform curved surface display effect. This is well known to those skilled in the art and will not be described in detail here. One or more inclined stud structures 400 are provided on the housing 201t in the inclined surface area 204. The number and position of the inclined stud structures 400 can be adjusted according to product requirements. Although the outer surface of the housing 201t in the inclined surface area 204 is curved, since the inclined stud structure 400 is relatively much smaller than the entire curved outer surface of the housing 201t, the outer surface of the housing 201t near the inclined stud structure 400 is relatively flat. Therefore, the outer surface of the housing 201t near the inclined stud structure 400 can be considered as an inclined surface. Therefore, the inclined stud structure 400 can be applied to either an inclined outer surface or a curved outer surface. The shell 201t of the inclined area 204 and the shell 201v of the vertical area 202 form an inclined angle θ (for example, +θ or -θ depending on the position of the inclined area 204). The absolute value of the inclined angle θ is, for example, between about 1 degree and 60 degrees, such as 10 degrees, but not limited to this, and can be adjusted according to product requirements.

[0097] Please refer to Figure 1 and Figure 2The material of the housing 201 can be, for example, metal or plastic, but is not limited to these. Metal materials may include stainless steel, aluminum, titanium, chromium, iron, cobalt, nickel, copper, zinc, or their alloys and layers, offering good protection and machinability, but are not limited to these; the choice depends on product requirements. If the housing 201 is made of metal, it can be formed into the required shape using processing techniques. Plastic materials may include engineering plastics or high-strength general-purpose plastics, but are not limited to these; the choice depends on product requirements. Plastic materials may include, for example, polyamide-imide (PAI), polybenzimidazole (PBI), polyetherimide (PEI), polyamide (PA), polycarbonate (PC), polyurethane (PU), polyethylene naphthalate (PEN), polyethylene terephthalate (PET), polyethersulfone (PES), fiber-reinforced plastics (FRP), poly(methylmethacrylate) (PMMA), polyetheretherketone (PEEK), or other suitable materials, or combinations thereof, but are not limited thereto. If the housing 201 is made of plastic, it can be molded to form the desired shape, for example.

[0098] Please refer to Figure 1 and Figure 2 One or more vertical stud structures 300 may be selectively provided on the outer surface of the housing 201v in the vertical plane region 202, for example... Figure 2 The vertical stud structures 300 are outlined by five dashed lines within the lower vertical area 202. On the outer surface of the housing 201t in the inclined area 204, inclined stud structures 400 can be provided at the locations of positioning holes, for example... Figure 2 The three inclined stud structures 400 are framed at the top of the upper inclined area 204. Since the stud angle of the inclined stud structure 400 can be adjusted to be approximately the same as that of the stud angle of the vertical stud structure 300, and is roughly parallel to the D2 axis, it is more convenient and more stable when assembling fixed structures such as brackets, for example, when using rivet screws for assembly.

[0099] Figure 3 This is a cross-sectional schematic diagram of a vertical stud structure according to an embodiment of the present invention. Please refer to... Figure 2 and Figure 3 The back cover 200 may optionally be provided with a vertical stud structure 300 in the housing 201v of the vertical plane region 202. The vertical stud structure 300 may include, for example, a base 310 and a stud portion 320, with the stud portion 320 fixed to the base 310. The stud portion 320 has a stud 322, a stud hole 324 within the stud 322, and a stud surface 326 on its top surface. The axial direction Av of the stud portion 320 is approximately parallel to the D2 axis direction, that is, the axial direction Av of the stud 322 and the stud hole 324 is approximately parallel to the D2 axis direction, or approximately perpendicular to the D3 axis direction. Threads (not shown) may be selectively added to the inner wall of the stud hole 324 of the stud 322 as needed. Therefore, when assembling a bracket to a wall, such as when using riveting screws for assembly, the vertical stud structure 300 is relatively easy to assemble because the angle is correct. The material of the vertical stud structure 300 can be referred to in the aforementioned description of the housing 201. It can be the same material as the housing 201 or a different material, which will not be repeated here. The above-described vertical stud structure 300 is only for illustrative purposes and is well known to those skilled in the art, so it will not be described in detail here.

[0100] Figure 4A This is a cross-sectional schematic diagram of an embodiment of the inclined stud structure of the present invention. Figure 4B This is a three-dimensional structural diagram of an embodiment of the inclined stud structure of the present invention. Please refer to... Figure 4A and Figure 4BThe back cover 200 has positioning holes 230 in the area of ​​the shell 201t in the inclined region 204 where riveting and locking are required. The outer surface of the shell 201t in the inclined region 204 can also be called the mounting plane. The inclined stud structure 400 is provided on the positioning holes 230, thereby adjusting the direction angle of the inclined stud to be the same as the direction angle of the vertical stud, so as to easily assemble the bracket. The inclined stud structure 400 includes at least an adjustment part 410, a stud part 420, and a positioning part 430. The adjustment part 410 is used to adjust the angle. The adjustment part 410 has a first surface 412 and a second surface 414 facing each other. The first surface 412 faces the shell 201t. There is a first included angle α between the adjustment part 410 and the shell 201t in the inclined region 204, which is approximately equal to the aforementioned inclined angle θ. The first included angle α is an acute angle, and the absolute value of the first included angle α is approximately between 1 degree and 60 degrees. The adjusting part 410 is approximately parallel to the housing 201v of the vertical surface area 202, and both are generally parallel to the D3 axis direction, thus solving the angle difference problem caused by the inclined surface area 204. The stud part 420 is coupled to and fixed to the second surface 414 of the adjusting part 410. The stud part 420 has a stud 422 and a stud hole 424 located within the stud 422, and the top surface of the stud 422 has a stud surface 426. The axial direction At of the stud part 420 is approximately parallel to the D2 axis direction, that is, the axial direction At of the stud 422 and the stud hole 424 is approximately parallel to the D2 axis direction and approximately perpendicular to the D3 axis direction. Threads (not shown) can be selectively added to the inner wall of the stud hole 424 of the stud 422 as needed. Therefore, when assembling the bracket on the wall, the angle (axial direction At) between the stud 422 and the stud hole 424 of the inclined stud structure 400 is approximately the same as the angle (axial direction Av) between the stud 322 and the stud hole 324 of the vertical stud structure 300, both being approximately parallel to the D2 axis direction. Therefore, assembly is easier and more stable than previous assembly methods using different angles. In this embodiment, the positioning part 430 is coupled to the first surface 412 of the adjustment part 410 and is inclined relative to the first surface 412. The positioning part 430 at least partially passes through the positioning hole 230 and is connected to and fixed to the housing 201t. In this embodiment, the positioning part 430 includes a protrusion 432 and a connecting post 434, with the connecting post 434 coupled between the adjustment part 410 and the protrusion 432. The protrusion 432 and the connecting post 434 are approximately perpendicular to the housing 201t of the inclined region 204. The cross-section of the protrusion 432 along the direction parallel to the housing 201t is approximately the same size as, or slightly smaller than, the positioning hole 230. The cross-section of the connecting post 434 along the direction parallel to the housing 201t has a length and width smaller than the width of the positioning hole 230. Therefore, the protrusion 432 can easily pass through the positioning hole 230 and, after rotating 90 degrees, can lock the housing 201t in place.The beveled stud structure 400 can be easily assembled onto the housing 201t without requiring any machining process on the housing 201t, greatly simplifying the complicated steps of stud angle adjustment and relatively reducing manufacturing costs.

[0101] To reduce displacement of the protrusion 432 after it engages with the housing 201t, one or more sets of limiting structures 450 can be selectively provided between the protrusion 432 and the housing 201t, including corresponding limiting protrusions 452 and limiting grooves 454. The limiting protrusions 452 engage with the limiting grooves 454 to reduce displacement. For example, the limiting protrusions 452 can be provided on the protrusion 432, and the limiting grooves 454 can be provided on the housing 201t, or vice versa, and can be adjusted according to requirements. Figure 4A As shown, the limiting structure 450 can be provided in two sets to increase the locking force between the protrusion 432 of the positioning part 430 and the housing 201t, and reduce the displacement of the protrusion 432 of the positioning part 430 after passing through the positioning hole 230.

[0102] Please refer to Figure 4A and Figure 4B The inclined stud structure 400 may optionally include an abutment portion 440. The abutment portion 440 may extend from the adjustment portion 410 near the housing 201t. The abutment portion 440 is coupled to the adjustment portion 410, with its first surface 442 and second surface 444 respectively connecting to the first surface 412 and second surface 414 of the adjustment portion 410, and the first surface 442 of the abutment portion 440 abutting against the housing 201t of the inclined region 204. The abutment portion 440 extends from one end of the adjustment portion 410 and bends relative to the second surface 414. A second included angle β is formed at the bend between the adjustment portion 410 and the abutment portion 440. The first included angle α and the second included angle β are approximately complementary, that is, the total of the first included angle α and the second included angle β is approximately 180 degrees (α + β = 180°). The contact portion 440 abuts against the housing 201t of the inclined area 204, which increases the stability of the adjustment portion 410. The contact portion 440 and the protrusion 432 form a clamping force with each other, stably securing it to the housing 201t and preventing it from falling off. In addition, another set of limiting structures 460 can be selectively provided between the contact portion 440 and the housing 201t to further enhance the stability of the inclined stud structure 400. For example, a limiting groove 464 is provided on the housing 201t, and a limiting protrusion 462 is provided at the corresponding position of the contact portion 440 to increase the stability after engagement. The material of the inclined stud structure 400 can be referred to the aforementioned description of the housing 201, and can be the same material as the housing 201 or a different material, which will not be elaborated here.

[0103] Please refer to Figure 4A and Figure 4BThe positioning part 430 of the inclined stud structure 400 at least partially passes through the positioning hole 230 and is connected to and fixed to the housing 201t. At the position of the positioning hole 230, the outer surface of the housing 201t of the inclined region 204 has a normal direction Nt. The axial direction At of the connecting post 434 of the inclined stud structure 400 forms a third included angle γ with the normal direction Nt, which is approximately equal to the aforementioned first included angle α or inclined angle θ. The third included angle γ is an acute angle, and the absolute value of the third included angle γ is approximately between 1 degree and 60 degrees.

[0104] Figures 5A to 5D This is a schematic diagram illustrating the assembly process of an inclined stud structure according to an embodiment of the present invention. In this embodiment, reference can be made to... Figure 4A and Figure 4B The embodiment described above. A set of the aforementioned limiting structures 460 is provided between the contact portion 440 and the housing 201t to further enhance the stability of the inclined stud structure 400. A limiting groove 464 is provided on the housing 201t, and a limiting protrusion 462 is provided at the corresponding position on the contact portion 440 to increase the stability after engagement. Please refer to... Figure 5A The protrusion 432 of the positioning portion 430 of the inclined stud structure 400 is aligned with the positioning hole 230 of the housing 201t. In this embodiment, the positioning hole 230 is designed to be rectangular, but this is not a limitation. The protrusion 432 is designed to correspond to the positioning hole 230, so the protrusion 432 can pass downward through the positioning hole 230 accordingly, such as... Figure 5B As shown. Please refer to. Figure 5C Then, rotate clockwise along the surface of the housing 201t. After rotating 90 degrees clockwise, the limiting protrusion 462 of the contact part 440 can be engaged with the limiting groove 464 of the housing 201t. In addition, in another set of limiting structures 450, the limiting protrusion 452 of the protrusion 432 can also be engaged with the limiting groove 454 of the housing 201t, thereby improving the stability after engagement.

Figure 6A and Figure 6BIn this embodiment, the positioning portion 430 of the aforementioned beveled stud structure 400 can also be replaced by the positioning portion 530 of this embodiment. The positioning portion 530 includes a connecting portion 532 coupled to the adjusting portion 410, and a pair of spring pieces 534 (including 534a and 534b) coupled to both sides of the connecting portion 532. The spring pieces 534a and 534b respectively have first sub-portions 542a, 542b and second sub-portions 544a, 544b. The first sub-portions 542a, 542b of the spring pieces 534a and 534b are respectively coupled between the connecting portion 532 and the second sub-portions 544a, 544b. At least one of the first sub-portions 542a or 542b of the spring piece 534a or spring piece 534b is bent outward. Figure 6B As shown, the first sub-part 542a of the spring piece 534a can be designed to be bent outwards, and the second sub-part 544a can be bent inwards. Alternatively, the first sub-part 542b of the spring piece 534b can be designed to be bent outwards, and the second sub-part 544b can be bent outwards further.

[0106] Figure 7A and Figure 7B These are three-dimensional structural schematic diagrams of the inclined stud structure according to another embodiment of the present invention. Please refer to... Figure 7A In another variation, the first sub-parts 542a and 542b of the spring pieces 534a and 534b can be designed to be bent outwards relative to the second sub-parts 544a and 544b, with the second sub-parts 544a and 544b continuing to bend outwards relative to the first sub-parts 542a and 542b. This design allows the spring pieces 534a and 534b to engage the housing 201t using their outwardly bent second sub-parts, providing a high degree of secure hold. This design also allows the use of relatively highly elastic spring pieces 534a and 534b, making it easier for them to deform and pass through the positioning hole 230, and to return to their original shape after passing through, thus engaging the housing 201t.

[0107] Please refer to Figure 7BIn another variation, the first sub-parts 542a and 542b of the spring pieces 534a and 534b can be designed to be bent outwards, while the second sub-parts 544a and 544b can be designed to be bent inwards relative to the first sub-parts 542a and 542b. This design allows the spring pieces 534a and 534b to pass through the positioning hole 230 more easily. The spring pieces 534a and 534b can be made of slightly higher rigidity and slightly lower elasticity, increasing their durability. The spring pieces 534a and 534b have a foot spacing C at the bend of the second sub-parts 544a and 544b, preferably greater than the positioning hole width B of the positioning hole 230 (C>B), so that the spring pieces 534a and 534b can still hold the housing 201t after passing through the positioning hole 230. After considering material tolerances, the distance C between the leads of springs 534a and 534b can be designed to be greater than the width B of the positioning hole 230 plus the spring width A of springs 534a and 534b, plus 0.2 cm (C>B+A+0.2). This design provides better stability for springs 534a and 534b after passing through the positioning hole 230. In another variation, one of springs 534a or 534b can also be designed as a straight strip (not shown), increasing the design flexibility of springs 534a or 534b.

[0108] Figure 8A and Figure 8B These are three-dimensional structural schematic diagrams of the inclined stud structure according to another embodiment of the present invention. Please refer to... Figure 8A The inclined stud structure 400 may optionally be equipped with an auxiliary support portion 550, coupled to the adjustment portion 410, and the auxiliary support portion 550 contacts the housing 201t. The auxiliary support portion 550 is coupled to the other end of the opposite engagement portion 532 and contacts the housing 201t, increasing the support for the adjustment portion 410. At the contact position between the auxiliary support portion 550 and the housing 201t, a limiting groove 250 may be selectively provided in the housing 201t, allowing the auxiliary support portion 550 to engage with the limiting groove 250, reducing the sliding or displacement of the inclined stud structure 400. Please refer to... Figure 8B The auxiliary support 550 can also be designed as an auxiliary support 560 to increase the contact area between the auxiliary support 560 and the housing 201t, thereby increasing the support strength. In addition, a limiting groove 260 can be selectively provided on the housing 201t so that the auxiliary support 560 can be engaged with the limiting groove 260, thereby reducing the sliding or displacement of the inclined stud structure 400.

[0109] Figure 9A and Figure 9B These are three-dimensional structural schematic diagrams of the inclined stud structure according to another embodiment of the present invention. Please refer to... Figure 9A and Figure 9BIn another variation, the positioning portion 430 of the aforementioned beveled stud structure 400 can also be replaced by the positioning portion 630 of this embodiment. In this embodiment, the thickness of the adjusting portion 410a is increased to facilitate the insertion of the stud portion 420a into the adjusting portion 410a. The positioning portion 630 includes a connecting portion 632 and a pair of spring tabs 634 (including 634a and 634b). The connecting portion 632 is coupled to the adjusting portion 410a, and due to the increased thickness of the adjusting portion 410a, the connecting portion 632 can move inward to engage with the side of the adjusting portion 410a. The spring tabs 634a and 634b are coupled to both sides of the connecting portion 632, and can be similar to Figure 7B The connection method of springs 534a and 534b can also be rotated 90 degrees, such as... Figure 9B The shrapnel 634a and 634b are examples. The design of shrapnel 634a and 634b can be referenced for further information. Figure 7B The shrapnel 534a and 534b will not be described in detail here.

[0110] In summary, the display device and its back cover of the present invention utilize an adjustment part of a beveled stud structure to adjust the angle between the adjustment part and the shell in the beveled area, making the adjustment part approximately parallel to the shell in the vertical area. This adjustment ensures that the studs in the beveled area and the studs in the vertical area have approximately the same angle. The beveled stud structure passes through a positioning hole and is fixed to the shell. Since assembly can be completed simply by the positioning part passing through the positioning hole, it is quite easy and simple, requiring no additional processing steps. This significantly simplifies the complex steps of adjusting the stud angle and relatively reduces manufacturing costs.
