[0032] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0033] See also Figure 1 , Figure 1 Schematic diagram of the structure of a television set in the prior art. In the existing television set 1, the television set 1 includes a display module 2, a circuit board 3 and a housing 4. The housing 4 is made of fireproof plastic to meet safety requirements, but the cost of fireproof plastic is high and not all parts of the television set 1 are likely to catch fire. Therefore, a large-area housing 4 made of fireproof plastic will cause a waste of resources.

[0034] The embodiment of the present application provides a television set that is fireproof and can reduce costs.

[0035] See also Figure 2 , Figure 2 The first structural schematic diagram of the television provided in the embodiment of the present application. The television 100 provided in the embodiment of the present application includes a television body 10 and a fireproof cover 20. The television body 10 includes a circuit board 11, a display module 12 and a housing 13. The display module 12 and the housing 13 form a receiving cavity 14, and the circuit board 11 is arranged in the receiving cavity 14. The fireproof cover 20 is arranged in the receiving cavity 14, and the fireproof cover 20 includes at least a first fireproof board 21 and a second fireproof board 22. The first fireproof board 21 is arranged on the side of the circuit board 11 close to the bottom 101 of the television body 10, and the second fireproof board 22 is arranged on the side of the circuit board 11 away from the display module 12.

[0036] Since the circuit board 11 concentrates a large number of electronic devices, it is easy to heat up during use, causing heat accumulation and thus causing a fire. The circuit board 11 is electrically connected to the display module 12 to control the display state of the display module 12. The housing 13 mainly plays the role of protecting and fixing the internal structure of the TV body 10. The circuit board 11 can be a power board and / or a core board.

[0037] When the TV body 10 is in use, the TV body 10 is often placed vertically, for example, the plane where the display screen in the display module 12 is located is placed vertically, which is convenient for users to watch. Relatively speaking, when the TV body 10 is in use, the TV body 10 has a relative bottom 101, top, side, etc. If the circuit board 11 catches fire, the dripping materials during burning will fall to the bottom 101 of the TV body 10 due to gravity, causing the fire to spread.

[0038] Please continue reading Figure 2 , the first fireproof board 21 and the second fireproof board 22 can be connected. The first fireproof board 21 and the second fireproof board 22 can be at an angle to each other, for example, 70 degrees to 110 degrees. The angle can be set according to the size of the accommodating cavity 14 and / or the size of the circuit board 11, and is not limited here. For example, the angle is 90 degrees, and the first fireproof board 21 and the second fireproof board 22 form an "L" shape. The first fireproof board 21 is arranged on the side of the circuit board 11 close to the bottom 101 of the TV body 10, which can better receive the burning drippings and prevent the spread of the fire. The second fireproof board 22 is arranged on the side of the circuit board 11 away from the display module 12. The second fireproof board 22 is arranged between the housing 13 with a lower ignition point and the circuit board 11 with a higher temperature during operation, which can effectively prevent the circuit board 11 from catching fire and causing an explosion and then causing a fire, greatly improving safety. Therefore, in the embodiment of the present application, a fireproof cover 20 is used at the position of the circuit board 11 that may cause a fire, so that the flame can be controlled within a smaller range when a fire occurs.

[0039] In some embodiments, see Figure 3 , Figure 3 A second structural schematic diagram of a television set provided in an embodiment of the present application. The fireproof cover 20 also includes a first fixing portion 24, which is connected to a side of the first fireproof board 21 away from the second fireproof board 22, and the first fixing portion 24 extends along the plane where the display module 12 is located, and the first fixing portion 24 is connected to the display module 12. The first fixing portion 24 and the first fireproof board 21 are at an angle to each other, and the angle can be set according to the shape of the display module 12 so as to fix the first fixing portion 24 to the display module 12, which is not limited here. For example, the angle is 90 degrees, the first fireproof board 21 and the first fixing portion 24 form an "L" shape, and the first fixing portion 24 is parallel to the plane where the display module 12 is located. The first fixing part 24, the first fireproof board 21 and the second fireproof board 22 are connected in sequence. When the relative position of the first fixing part 24 and the display module 12 is fixed, that is, the relative position of the first fixing part 24 and the circuit board 11 is fixed, the relative positions of the first fireproof board 21, the second fireproof board 22 and the circuit board 11 are all fixed.

[0040] Since the first fireproof board 21 and the second fireproof board 22 of the fireproof cover 20 form a fireproof space 23, the circuit board 11 is arranged in the fireproof space 23. The first fixing portion 24 is arranged outside the fireproof space 23, that is, the first fixing portion 24 can extend along the plane where the display module 12 is located toward a side away from the circuit board 11, so as to facilitate the fixing of the first fixing portion 24 and the display module 12.

[0041] The first fixing portion 24 and the display module 12 are fixedly connected by screws, hooks, glue or hot riveting.

[0042] In some cases, as Figure 3 The second fireproof board 22 is spaced apart from the shell 13, that is, the second fireproof board 22 is not in contact with the shell 13. This can prevent the speaker on the circuit board 11 from vibrating when the volume is high. The second fireproof board 22 vibrates accordingly and is transmitted to the shell 13 of the TV 100, causing the shell 13 to produce vibration sound, that is, avoiding the generation of vibration sound.

[0043] In other cases, see 4, Figure 4 A third structural schematic diagram of a television set provided in an embodiment of the present application. A through hole is provided on the shell 13, and the fireproof cover 20 also includes a second fixing portion 25, the second fixing portion 25 is provided on the peripheral side of the second fireproof board 22, the second fireproof board 22 is penetrated through the through hole, and the second fixing portion 25 overlaps the side of the shell 13 close to the display module 12. It can be understood that the second fireproof board 22 is a part of the shell 13. In the embodiment of the present application, the fireproof cover 20 is used at the position of the circuit board 11 that may cause fire, so that the flame can be controlled within a smaller range when a fire occurs, and the fireproof cover 20 can be used as a part of the shell 13 to play a decorative role.

[0044] In some embodiments, see Figure 5 as well as Figure 6 , Figure 5 This is a fourth structural schematic diagram of a television provided in an embodiment of the present application, Figure 6The fifth structural schematic diagram of the television provided in the embodiment of the present application. A fixed card slot 121 is provided on the side of the display module 12 close to the shell 13, the first fireproof board 21 is snapped into the fixed card slot 121, and the second fireproof board 22 is connected to the shell 13. The TV body 10 includes a first protrusion 122 and a second protrusion 123, the first protrusion 122 and the second protrusion 123 are arranged on the side of the display module 12 close to the shell 13, and the first protrusion 122, the second protrusion 123 and the display module 12 are surrounded to form a fixed card slot 121, which can fix the free end of the first fireproof board 21. By fixing one end of the first fireproof board 21, it can be avoided that after the circuit board 11 catches fire, the air expansion causes impact deformation to the first fireproof board 21, which further increases the gap between the first fireproof board 21 and the display module 12, and fails to prevent the spread of fire.

[0045] Among them, along the thickness direction of the TV body 10, the distance between the first fireproof board 21 and the display module 12 is less than 1mm, that is, it has a fireproof effect.

[0046] In some cases, please continue to see Figure 5 The fireproof cover 20 further includes a third fixing portion 26, which is disposed on the circumference of the second fireproof plate 22 and connected to the housing 13. The fireproof cover 20 is attached to a side of the housing 13 close to the display module 12. The third fixing portion 26 is fixed to the housing 13 by screws, hooks, adhesives or hot riveting.

[0047] In other cases, please continue to Figure 6 , the shell 13 is provided with a through hole, the fireproof cover 20 also includes a fourth fixing portion 27, the fourth fixing portion 27 is arranged on the peripheral side of the second fireproof board 22, the second fireproof board 22 is penetrated through the through hole, and the fourth fixing portion 27 overlaps with the side of the shell 13 close to the display module 12. It can be understood that the second fireproof board 22 is used as a part of the shell 13. In the embodiment of the present application, the fireproof cover 20 is used at the position of the circuit board 11 that may cause fire, so that the flame can be controlled within a smaller range when a fire occurs, and the fireproof cover 20 can be used as a part of the shell 13 to decorate the shell 13.

[0048] In some embodiments, the fireproofing grade of the material of the fireproof cover 20 is greater than the fireproofing grade of the material of the housing 13. For example, the material of the fireproof cover 20 is V0-grade fireproof material, and the material of the housing 13 is HB-grade ordinary plastic. Since the area and volume of the fireproof cover 20 are smaller than those of the material of the housing 13, the material cost of the television 100 can be reduced.

[0049] When the material of the fireproof cover 20 is metal, the television 100 further includes an insulating layer, which is disposed between the fireproof cover 20 and the circuit board 11. For example, the material of the fireproof cover 20 is a fire-resistant metal such as tinplate or galvanized steel sheet. Metal is conductive, and in order to prevent the fireproof cover 20 from contacting the circuit board 11 and causing a short circuit, an insulating layer is disposed between the fireproof cover 20 and the circuit board 11 to separate the fireproof cover 20 and protect the circuit board 11.

[0050] See also Figure 7 , Figure 7 The structural schematic diagrams of the ventilation holes provided in the embodiments of the present application are as follows: Figure (1) is a structural schematic diagram of the ventilation hole having a circular shape; Figure (2) is a structural schematic diagram of the ventilation hole having a rectangular shape; Figure (3) is a structural schematic diagram of the ventilation hole having a round-headed long hole shape.

[0051] In some embodiments, the first fireproof board 21 is provided with ventilation holes 211. In some cases, the housing 13 is provided with heat dissipation holes corresponding to the ventilation holes 211 on the first fireproof board 21. When the relative positions of the first fireproof board 21 and the housing 13 are fixed, the ventilation holes 211 correspond to the heat dissipation holes, which can effectively prevent fire while maintaining the original heat dissipation and ventilation effects.

[0052] The shape of the ventilation hole 211 can be circular and / or elongated. The ventilation hole 211 is used to dissipate heat to prevent heat from being unable to dissipate, so that it can not only maintain the strength of the first fireproof board 21, but also have the advantage of ventilation and heat dissipation.

[0053] See also Figure 7 (1) When the ventilation hole 211 is circular in shape, the diameter of the ventilation hole 211 is less than or equal to 3 mm. The ventilation holes 211 may be distributed in an array on the first fireproof plate 21 .

[0054] See also Figure 7 (2) and Figure 7 (3) When the ventilation hole 211 is in the shape of a long strip, the long strip hole can also be called a waist hole, an oblong hole, or a rectangular hole. Figure 7 (2) and round head long hole, such as Figure 7 (3) At this time, the length L1 of the ventilation hole 211 is not limited, and the hole diameter W perpendicular to the length direction is less than 1 mm.

[0055] The different shapes of the ventilation holes 211 described in the embodiments of the present application can be selected according to actual conditions to ensure the strength of the first fireproof board 21, which has fireproof properties and has the advantage of ventilation and heat dissipation.

[0056] In some embodiments, see Figure 8 , Figure 8A schematic diagram of the orthographic projections of a circuit board and a second fireproof board on a display module provided in an embodiment of the present application. The orthographic projection of the circuit board 11 on the display module 12 is located in the orthographic projection of the second fireproof board 22 on the display module 12. The area of ​​the orthographic projection of the circuit board 11 on the display module 12 is smaller than the area of ​​the orthographic projection of the second fireproof board 22 on the display module 12. For example, the distance between the side edge of the orthographic projection of the second fireproof board 22 on the display module 12 and the corresponding side edge of the orthographic projection of the circuit board 11 on the display module 12 is as follows: Figure 7 L2, L3 or L4, the minimum value of L2 and L3 is 15mm, and the minimum value of L4 is 53mm, which can achieve better fire prevention effect.

[0057] The television set 100 provided in the embodiment of the present application includes a television body 10 and a fireproof cover 20. The television body 10 includes a circuit board 11, a display module 12 and a housing 13. The fireproof cover 20 is fixed between the housing 13 and the television set 100. The circuit board 11 is the place where heat and fire are most likely to occur. The fireproof cover 20 is only arranged at the corresponding part of the circuit board 11, which can greatly prevent the spread of flames and reduce costs. The fireproof cover 20 includes a first fireproof board 21 and a second fireproof board 22. The first fireproof board 21 is arranged on the side of the circuit board 11 close to the bottom 101 of the television body 10. If a fire occurs, the first fireproof board 21 can better receive burning drippings to prevent the spread of fire; the second fireproof board 22 is arranged on the side of the circuit board 11 away from the display module 12. The second fireproof board 22 is arranged between the housing 13 with a lower ignition point and the circuit board 11 with a higher temperature during operation, which can effectively prevent the circuit board 11 from catching fire and causing explosions and then causing fires, greatly improving safety.
