Description

Technical Field

[0001] This utility model relates to the field of display device technology, and in particular to a fireproof baffle for a display device and a display device. Background Technology

[0002] With industry development and technological innovation, the pace of product updates for consumer electronics is rapid, and industry safety standards are constantly changing, leading to increasingly stringent safety and fire protection requirements for electronic products. For example, high-power power boards or PIS3 circuits (PIS3 circuits refer to any circuit with a power source exceeding 100 watts or whose power source is not yet classified) need to meet higher fire protection requirements, thus placing new demands on the casing and component layout design of new products.

[0003] However, older models that have already been produced or are currently in production may not meet the new safety standards. Therefore, they face the situation of either redesigning the casing or changing the casing material to use materials with higher flame retardant properties. Either way, a large number of old casings will be discarded, and the production schedule will be extended, increasing production costs.

[0004] Therefore, existing technologies still need to be improved and developed. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a fireproof baffle for a display device and a display device, which aims to solve the problem that the display devices of old models cannot meet the new safety standards, and that the cost of remanufacturing them is high and affects the production speed.

[0006] The technical solution of this utility model is as follows:

[0007] A fireproof baffle for a display device, wherein the display device includes a sheet metal bracket and a drive plate assembled on the sheet metal bracket, the drive plate having a plurality of electrical components; the fireproof baffle includes a connecting portion and a shielding portion, the connecting portion being connected to the sheet metal bracket and disposed on the side of the drive plate; the shielding portion being connected to the connecting portion and disposed on the connecting portion on the side away from the sheet metal bracket; the shielding portion extending toward the drive plate for shielding the highest electrical component on the drive plate.

[0009] The fireproof baffle of the display device, wherein a rectangular array of several heat dissipation holes is located on the second connecting section.

[0010] The fireproof baffle of the display device, wherein the diameter of the heat dissipation hole is 2.5-3mm.

[0017] Compared with the prior art, the embodiments of this utility model have the following advantages:

[0018] The fireproof baffle disclosed in this utility model is installed on the sheet metal bracket of the display device, located on the side of the driver board, forming a barrier.

Detailed Implementation

[0026] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Variations in the shapes shown in the accompanying drawings may occur due to manufacturing techniques and / or tolerances. Therefore, the examples described herein are not limited to the specific shapes shown in the accompanying drawings, but include changes in shape that may occur during manufacturing.

[0028] As used herein, the term “and / or” includes any one of the relevant items listed and any combination of any two or more items.

[0029] Although terms such as “first,” “second,” and “third” may be used herein to describe individual components, assemblies, regions, layers, or parts, these components, assemblies, regions, layers, or parts are not limited by these terms. Rather, these terms are used only to distinguish one component, assembly, region, layer, or part from another. Therefore, without departing from the teachings of the examples described herein, the first component, assembly, region, layer, or part referred to as the second component, assembly, region, layer, or part may also be referred to as the second component, assembly, region, layer, or part.

[0030] For ease of description, spatial relational terms such as “above,” “upper,” “below,” and “lower” are used herein to describe the relationship between one element and another, as shown in the accompanying drawings. Such spatial relational terms are intended to encompass not only the orientation depicted in the drawings but also different orientations of the device during use or operation. For example, if the device in the drawings is flipped, an element described as being “above” or “upper” relative to another element will subsequently be “below” or “lower” relative to that other element. Therefore, the term “above” includes both “above” and “below” orientations depending on the spatial orientation of the device. The device may also be positioned in other ways, and the spatial relational terms used herein will be interpreted accordingly.

[0031] The terminology used herein is for the purpose of describing various examples only and is not intended to limit this disclosure. Unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. The terms “comprising,” “including,” and “having” enumerate the stated features, quantities, operations, components, elements, and / or combinations thereof, but do not exclude the presence or addition of one or more other features, quantities, operations, components, elements, and / or combinations thereof.

[0032] In existing technologies, the production standards for display devices are constantly being updated, and the requirements for the fire resistance of display devices are becoming increasingly stringent. Currently, for high-power power boards or PIS3 circuit boards, the surrounding middle shell, back shell, and other structures need to be made of materials with a flame retardant rating of V0, or sufficient safety distance must be maintained between the shell and the board material. Specifically, according to industry safety standards, a sphere with a diameter of 15 mm is constructed with the highest point on the power board or circuit board as its center; and a cone is constructed vertically upwards 50 mm from the center of the sphere as its bottom center. No flammable or slow-burning substances are allowed within the lower hemispheres of the cone and sphere, and no flammable or slow-burning substances are allowed in the vertically downward direction extending infinitely from the lower hemispheres of the cone and sphere.

[0033] See Figure 1 , Figure 2 and Figure 3 In one embodiment of this utility model application, a fireproof baffle 40 for a display device is disclosed. The display device includes a sheet metal bracket 10 and a drive plate 20 assembled on the sheet metal bracket 10. The drive plate 20 is provided with a plurality of electrical components 30. The fireproof baffle 40 includes a connecting part 41 and a blocking part 42. The connecting part 41 is connected to the sheet metal bracket 10 and is located on the side of the drive plate 20. The blocking part 42 is connected to the connecting part 41 and is located on the side of the connecting part 41 away from the sheet metal bracket 10. The blocking part 42 extends toward the drive plate 20 and is used to block the highest electrical component 30 on the drive plate 20.

[0034] The display devices disclosed in this embodiment include, but are not limited to, flat-panel TVs, LCD screens, all-in-one computers, and other electronic devices. These display devices are generally placed at an angle or vertically to emit light forward for easy image display. In this case, the sheet metal bracket 10 and the drive board 20 are both vertically or at an angle. In this embodiment, a fireproof baffle 40 is placed on the underside of the drive board 20 to prevent flames from spreading downwards, and a shielding portion 42 is formed to cover the highest electrical component 30 on the drive board 20, thereby preventing flames from spreading to the rear of the display device and achieving a fireproof effect.

[0035] As can be seen, by adding a fireproof baffle 40 to the original structure of the display device in this embodiment, the possibility of continuous burning or spread of flames in the event of a fire can be reduced, thereby improving the safety of the display device. Without adjusting the original design of the display device, the fire resistance of the display device is increased, thus meeting existing safety production standards, reducing the cost of re-molding or redesigning the display device, reducing resource waste, enabling rapid product upgrades, and increasing production speed.

[0036] In this embodiment, the sheet metal bracket 10 is connected to the housing of the display device. Specifically, six M3X6 studs with a height of 5mm are riveted to the sheet metal bracket 10 to connect it to the middle shell of the display device. The drive board 20 is connected to the sheet metal bracket 10 by riveting six M3X4 screws. The screw connection improves the connection between the sheet metal bracket 10 and the drive board 20, as well as the assembly accuracy, making the overall structure of the display device robust and reliable, convenient for transportation, and beneficial for long-term use.

[0037] like Figure 1 and Figure 2 As shown in this embodiment, the plane on the sheet metal bracket 10 where the drive plate 20 is assembled is a mounting plane 11. The connecting part 41 includes a first connecting section 411 and a second connecting section 412. The first connecting section 411 is laid flat on the mounting plane 11. The first connecting section 411 is provided with a plurality of mounting through holes 4111. The sheet metal bracket 10 is provided with mounting grooves 12 corresponding to the positions of the mounting through holes 4111. The first connecting section 411 is assembled onto the sheet metal bracket 10 by setting screws to pass through the mounting through holes 4111 and insert into the mounting grooves 12.

[0038] In this embodiment, by setting the first connecting segment 411 to contact the assembly plane 11, the connecting part 41 is partially fitted with the sheet metal bracket 10 to facilitate drilling and assembling rivets, forming a stable and firm connection. Specifically, the assembly groove 12 can be arranged in a straight line along a direction parallel to the edge of the drive plate 20, which serves to position the connecting part 41, making the connecting part 41 parallel to the edge of the drive plate 20, without interfering with the drive plate 20, and maintaining a sufficient safety distance.

[0039] like Figure 2 As shown, in this embodiment, the first connecting segment 411 is elongated. Assembly holes 4111 are provided at both ends and the midpoint of the first connecting segment 411. Three M3X4 screws can be used to connect the fireproof baffle 40 and the sheet metal bracket 10, providing a stable connection effect.

[0040] For example Figure 2As shown, the second connecting segment 412 disclosed in this embodiment is connected to the first connecting segment 411 and is arranged perpendicular to the assembly plane 11; the shielding part 42 is provided on the second connecting segment 412 on the side away from the sheet metal bracket 10; the second connecting segment 412 is provided with a plurality of heat dissipation holes 4121.

[0041] The second connecting segment 412 disclosed in this embodiment forms a side shield, which can block the spread of flames when the drive board 20 is accidentally on fire; at the same time, when the drive board 20 is in normal use, it needs to dissipate heat quickly, so several heat dissipation holes 4121 are provided to facilitate gas flow, increase the heat dissipation speed of the drive board 20, and reduce the surface temperature of the drive board 20.

[0042] For example Figure 1 and Figure 2 As shown, in another embodiment of this invention, a rectangular array of several heat dissipation holes 4121 is disclosed on the second connecting segment 412. In this embodiment, by arraying multiple heat dissipation holes 4121, the number of airflow channels is increased, further improving the heat dissipation efficiency of the drive board 20 surface.

[0043] Specifically, as another embodiment of this invention, the diameter of the heat dissipation hole 4121 is disclosed to be 2.5-3mm. When the diameter of the heat dissipation hole 4121 is less than 2.5mm, the heat dissipation effect is poor; when the diameter of the heat dissipation hole 4121 is greater than 3mm, it is easy for flames to pass through. Therefore, in this embodiment, the diameter of the heat dissipation hole 4121 is set in the range of 2.5-3mm. When the drive board 20 is working normally, the heat dissipation hole 4121 is used for heat dissipation of the drive board 20. Once the drive board 20 is burning, the heat dissipation hole 4121, due to its small space and insufficient air passage, can block the spread of flames. Preferably, the diameter of the heat dissipation hole 4121 is set to 3mm, but in actual manufacturing, considering material tolerance control, the actual diameter of the hole is 2.8mm.

[0044] Specifically, as another embodiment of this invention, the height of the second connecting segment 412 along the direction perpendicular to the assembly plane 11 is disclosed to be greater than or equal to 19 mm. In this embodiment, the highest electrical component 30 on the drive board 20 is a capacitor, located 15 mm from the surface of the drive board 20. The maximum height of other electrical components is 2.4 mm. According to safety production regulations, the shielding part 42 must maintain a safety distance of at least 4 mm when covering the capacitor. That is, the distance between the shielding part 42 and the surface of the drive board 20 is at least 19 mm. In this embodiment, the height of the second connecting segment 412 is set to at least 19 mm to ensure a safe distance between the shielding part 42 and the drive board 20, thereby preventing the spread of flames.

[0045] like Figure 4As shown, in another embodiment of this invention, the area projected by the drive board 20 on the surface of the second connecting segment 412 is disclosed as the central area, and a first protection zone 4122 and a second protection zone 4123 are respectively provided on both sides of the central area; the width of the first protection zone 4122 is greater than or equal to 15mm, and the width of the second protection zone 4123 is greater than or equal to 15mm.

[0046] In this embodiment, the second connecting segment 412 is located on the side of the drive plate 20. Besides the portion directly opposite the drive plate 20, it also includes a first protective zone 4122 and a second protective zone 4123. This extends the shielding of the drive plate 20, reducing the probability that flames will bypass the drive plate 20 during combustion, further improving fire prevention and reducing the likelihood of flame spread. The widths of the first protective zone 4122 and the second protective zone 4123 are also set to at least 15mm according to safety production regulations, effectively blocking the flames.

[0047] Specifically, as another embodiment of this invention, the connecting portion 41 and the shielding portion 42 are integrally formed by sheet metal processing. In this embodiment, the connecting portion 41 is perpendicular to the assembly plane 11, and the shielding portion 42 is parallel to the assembly plane 11, forming an L-shape. It can be formed by bending in sheet metal processing, which is fast, has low production cost, and high structural strength, making it less prone to deformation.

[0048] Specifically, the sheet metal bracket 10 and the fireproof bracket disclosed in this embodiment can be made of the same material, such as aluminum alloy or steel plate. For example, both can be made of 0.6mm steel plate through sheet metal processing. This reduces the types of materials used in the parts, lowers production costs, and facilitates mass production. Especially for older display devices, if the number of replacements is small, the fireproof baffle 40 can be obtained through CNC machining, avoiding the need for new molds and reducing large mold costs. When there are bulk orders, simple sheet metal molds can be used to achieve fast, low-cost production.

[0049] like Figure 3 As shown, in another embodiment of this invention, the fireproof baffle 40 further includes a reinforcing rib 43, one end of which is connected to the connecting part 41 and the other end is connected to the shielding part 42, forming a triangular support structure.

[0050] In this embodiment, the shielding part 42 is connected to the connecting part 41 on one side and suspended on the other side. Therefore, a reinforcing rib 43 is provided to enhance the stability of the shielding part 42. The reinforcing rib 43 is located at the connection between the shielding part 42 and the connecting part 41, forming a triangular support structure with stability.

[0051] Specifically, as another embodiment of this invention, the reinforcing rib 43 is integrally formed at the connection position between the connecting portion 41 and the shielding portion 42 by a stamping process. The reinforcing rib 43 disclosed in this embodiment is manufactured by stamping, eliminating the need for separate assembly manufacturing, thus simplifying operation and improving production efficiency. Specifically, in this embodiment, the fireproof baffle 40 can be formed by bending a sheet material to create the shielding portion 42, and the reinforcing rib 43 can be stamped at the bend, making manufacturing convenient, simple, and efficient.

[0052] As another embodiment of this application, a display device is disclosed, which includes a fireproof baffle 40 as described in any of the above-described display devices.

[0053] In summary, this application discloses a fireproof baffle 40 for a display device. The display device includes a sheet metal bracket 10 and a drive plate 20 assembled on the sheet metal bracket 10. The drive plate 20 has a plurality of electrical components 30. The fireproof baffle 40 includes a connecting portion 41 and a shielding portion 42. The connecting portion 41 is connected to the sheet metal bracket 10 and is located on the side of the drive plate 20. The shielding portion 42 is connected to the connecting portion 41 and is located on the side of the connecting portion 41 away from the sheet metal bracket 10. The shielding portion 42 extends toward the drive plate 20 to shield the highest electrical component 30 on the drive plate 20. Without adjusting the original design of the display device, the fireproof performance of the display device is improved, thereby meeting existing safety production standards, reducing the cost of re-molding or redesigning the display device, reducing resource waste, enabling rapid product upgrades, and increasing production speed.

[0054] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0055] It should be noted that this utility model uses a fireproof baffle for a display device and a display device as examples to introduce the specific structure and working principle of this utility model. However, the application of this utility model is not limited to fireproof baffles for display devices and display devices, and can also be applied to the production and use of other similar workpieces.
