Description

Technical Field

[0001] This invention relates to the field of LCD TV housings, and more particularly to a protective housing for LCD displays. Background Technology

[0002] In pursuit of simplicity and aesthetics, modern interior design often places LCD TV screens inside the wall, creating a concealed installation. However, this type of wall-mounted LCD TV relies on a mounting bracket on the back of the casing to be fixed to the wall. This means that when dealing with a large, heavy LCD TV screen, the mounting bracket on the back of the casing experiences significant tension, which can lead to a risk of it slipping off over time. Summary of the Invention

[0003] To overcome the drawback that the mounting bracket on the back of the rear cover is subjected to large tensile forces when facing heavy, large-size LCD TV displays, and that long-term use may cause the mounting bracket to slip off, this invention provides a protective housing for LCD displays.

[0004] The technical solution of the present invention is as follows: a protective housing for a liquid crystal display screen, comprising a fixed frame and a display panel detachably connected to the fixed frame; further comprising a rear shell; the fixed frame is detachably connected to the rear shell; a mounting plate is fixed to the back of the rear shell; the rear shell has a plurality of heat dissipation holes; four rectangularly distributed support plates are rotatably connected to the rear shell; four miniature electric push rods are installed on the rear shell; each miniature electric push rod has a spring rod I installed at its telescopic end, and the telescopic end of the spring rod I is movably connected to the corresponding support plate; each miniature electric push rod has a sealing plate installed at its telescopic end, and the sealing plate is aligned with the corresponding heat dissipation hole.

[0005] More preferably, it also includes a spring rod II; the rear shell is equipped with a plurality of spring rods II, and the telescopic ends of every two spring rods II are movably connected to the corresponding support plate.

[0006] More preferably, it also includes a sealing ring; the rear cover is equipped with several sealing rings, and the number and position of the sealing rings correspond to the heat dissipation holes.

[0007] More preferably, the sealing ring is made of sponge material.

[0008] More preferably, it also includes an elastic mesh; each support plate is equipped with an elastic mesh, and the elastic mesh is connected to the rear shell.

[0009] More preferably, each support plate has several circular holes.

[0010] More preferably, the round holes and heat dissipation holes are arranged alternately.

[0011] More preferably, the support plate is made of a thermally conductive material.

[0012] More preferably, it also includes spring rods III, cover plates, and retaining plates; the rear housing has several cable interfaces for plugging cables; the rear housing is equipped with several spring rods III; each pair of spring rods III has a cover plate connected to its telescopic end; each cover plate has several through holes corresponding to the number and position of the cable interfaces; each cover plate is equipped with several deformable retaining plates, and the number and position of the retaining plates correspond to the through holes.

[0013] More preferably, the telescopic end of spring rod III is detachably connected to the cover plate.

[0014] Compared with the prior art, the present invention has the following advantages: The present invention controls the micro electric push rod to drive the spring rod I to rotate the corresponding support plate towards the side closer to the wall until the support plate is tightly attached to the inner side of the wall. The spring rod I is compressed, and then the support plate provides auxiliary support for the fixed frame, the display panel and the back shell in four directions, reducing the tension on the mounting plate on the back of the back shell and reducing the risk of the mounting plate on the back of the back shell slipping off due to long-term use.

[0015] When the LCD TV is not in use, the micro electric push rod is controlled to make the spring rod I continue to move the corresponding support plate closer to the wall, so that the spring rod I is further compressed. At this time, the extension end of the micro electric push rod drives the sealing plate to move towards the heat dissipation hole until the sealing plate covers the corresponding heat dissipation hole, thereby sealing the heat dissipation hole and preventing dust in the air from entering the back shell through the heat dissipation hole.

[0016] By increasing the support area of ​​the support plate through spring rod II, the vibration from the support plate is buffered and absorbed, reducing the vibration generated by the back shell and display panel. At the same time, the support and buffering effect of the support plate is improved by spring rod I at the telescopic end of the miniature electric push rod. Attached Figure Description

Detailed Implementation

[0027] Although the invention may be described with respect to specific applications or industries, those skilled in the art will recognize its broader applicability. Those skilled in the art will understand that terms such as "above," "below," "upward," "downward," etc., are used to describe the drawings and not to indicate a limitation on the scope of the invention as defined by the appended claims. Any numerical designations such as "first" or "second" are merely illustrative and not intended to limit the scope of the invention in any way.

[0028] Example 1: A protective housing for a liquid crystal display screen, such as Figures 1-7 As shown, it includes a fixed frame 1 and a display panel 2; the fixed frame 1 is detachably connected to the display panel 2;

[0029] It also includes a rear shell 101, a support plate 102, a miniature electric push rod 103, a spring rod I 104, and a sealing plate 108; the fixed frame 1 is connected to the rear shell 101 by a snap fastener; an mounting plate is fixed to the back of the rear shell 101; the rear shell 101 has several heat dissipation holes 11; the rear shell 101 is rotatably connected to four rectangularly distributed support plates 102, and the support plates 102 are inclined, so as to quickly guide the heat blown out from the heat dissipation holes 11 to the outside of the wall 3, thereby accelerating the heat dissipation efficiency; the rear shell 101 is bolted to several miniature electric push rods 103 with four rectangularly distributed parts; each miniature electric push rod 103 has a spring rod I 104 installed at its telescopic end, and the telescopic end of the spring rod I 104 is hinged to the corresponding support plate 102; each miniature electric push rod 103 has a sealing plate 108 installed at its telescopic end, and the sealing plate 108 is aligned with the corresponding heat dissipation hole 11.

[0030] It also includes spring rods II 105; the rear housing 101 is equipped with several spring rods II 105, and the telescopic ends of every two spring rods II 105 are hinged to the corresponding support plate 102.

[0031] It also includes a sealing ring 106; several sealing rings 106 are installed on the inner side of the rear shell 101, and the number and position of the sealing rings 106 correspond to the heat dissipation holes 11. When the sealing plate 108 covers the sealing rings 106, the heat dissipation holes 11 are sealed by the sealing rings 106, thereby blocking dust and impurities in the air and enhancing the sealing effect of the heat dissipation holes 11.

[0032] The sealing ring 106 is made of sponge material.

[0033] It also includes an elastic net 107; each support plate 102 is equipped with an elastic net 107, and the elastic net 107 is connected to the rear shell 101.

[0034] Each support plate 102 has several round holes 21, which facilitate the dissipation of heat from the back of the rear shell 101 to the outside of the wall 3 through the round holes 21, thereby improving the heat dissipation efficiency of the back of the rear shell 101.

[0035] The circular holes 21 and the heat dissipation holes 11 are staggered to reduce the overlap area between the heat coming out of the circular holes 21 and the heat coming out of the heat dissipation holes 11, and to prevent the heat coming out of the circular holes 21 and the heat coming out of the heat dissipation holes 11 from entering each other's holes, which would reduce the heat dissipation efficiency.

[0036] The support plate 102 is made of thermally conductive material, which allows the heat on the back of the rear shell 101 to be transferred to the outside of the wall 3 more quickly through the thermal conductivity of the support plate 102, thereby further improving the heat dissipation efficiency of the back of the rear shell 101.

[0037] In use, the mounting frame 1, display panel 2, and components are installed on the back cover 101 to form a complete LCD TV. Then, the mounting plate on the back of the back cover 101 is fixed to the inside of the wall 3 with bolts. The installation angle of the back cover 101 is adjusted so that the mounting frame 1 and display panel 2 are parallel to the wall 3. Subsequently, the micro electric push rod 103 is controlled to cause the spring rod I 104 to rotate the corresponding support plate 102 towards the side closer to the wall 3 until the support plate 102 is tightly pressed against the inside of the wall 3, and the spring rod I 104 is compressed. Figure 3 As shown, the support plate 102 provides auxiliary support to the fixed frame 1, the display panel 2, and the back cover 101 in four directions, reducing the tension on the mounting plate on the back of the back cover 101 and lowering the risk of the mounting plate slipping off the back of the back cover 101 due to long-term use. The heat generated inside the back cover 101 is dissipated to the outside through the heat dissipation holes 11 around the back cover 101, ensuring heat dissipation efficiency. When the LCD TV is not in use, the micro electric push rod 103 is controlled to make the spring rod I 104 continue to drive the corresponding support plate 102 to move closer to the wall 3. Since the support plate 102 is blocked by the wall 3 and cannot move, the spring rod I 104 is further compressed. At this time, the telescopic end of the micro electric push rod 103 drives the sealing plate 108 to move towards the side of the heat dissipation hole 11 until the sealing plate 108 covers the corresponding heat dissipation hole 11, thereby sealing the heat dissipation hole 11 and preventing dust in the air from entering the back cover 101 through the heat dissipation hole 11.

[0038] Considering that building floors will vibrate during daily use, this vibration is transmitted through the wall 3 to the support plate 102, and then through the support plate 102 to the electronic components and display panel 2 inside the rear shell 101. Long-term use may cause damage. To solve this problem, the support area of ​​the support plate 102 is increased by the spring rod II 105 to buffer and absorb the vibration from the support plate 102, thereby reducing the vibration generated by the rear shell 101 and the display panel 2. At the same time, the spring rod I 104 at the telescopic end of the miniature electric push rod 103 improves the support and buffering effect of the support plate 102.

[0039] Since the sealing ring 106 is made of sponge material, when the sealing plate 108 covers the sealing ring 106, the sponge material of the sealing ring 106 absorbs moisture in the air, preventing moisture in the air from seeping into the back cover 101 through the heat dissipation hole 11 and the sealing ring 106, thereby improving the moisture-proof performance of the back cover 101 in humid weather and further enhancing the sealing effect.

[0040] Furthermore, the elastic mesh 107 covers the heat dissipation holes 11 and the support plate 102 without affecting the heat dissipation function, thereby improving the overall aesthetics. When the support plate 102 rotates, the elastic mesh 107 undergoes adaptive deformation under its own elastic force.

[0041] Example 2, based on Example 1, such as Figures 8-9 As shown, it also includes a spring rod Ⅲ 201, a cover plate 202, and a retaining plate 203; the rear shell 101 has several cable interfaces 12; the rear shell 101 is equipped with several spring rods Ⅲ 201; each of the telescopic ends of every two spring rods Ⅲ 201 is connected to a cover plate 202; each cover plate 202 has several through holes 31, and the number and position of the through holes 31 correspond to the cable interfaces 12; each cover plate 202 is equipped with several deformable retaining plates 203, and the number and position of the retaining plates 203 correspond to the through holes 31.

[0042] The telescopic end of the spring rod Ⅲ201 is detachably connected to the cover plate 202, allowing for easy disassembly and replacement of the cover plate 202 when installing the rear shell 101 with different hole positions. This makes the cover plate 202 adaptable to rear shells 101 with different hole positions, thus improving the adaptability of the cover plate 202.

[0043] Considering that the cables of the concealed LCD screen are usually connected to the back of the back cover 101, but when a large number of cables need to be connected for wiring, the cables will be bent, which makes the cables prone to bending and deformation at the cable interface 12. This may lead to the risk of the cables loosening at the cable interface 12 during later use. To solve this problem, when installing the cables, multiple cables are manually passed through the corresponding through holes 31 on the cover plate 202. The clamping plate 203 adapts to the deformation and fixes the cables in place, preventing the cable interface 12 from loosening when the cables are pulled. Even if a person or a child accidentally pulls the cable located outside the wall 3 during later use, the cable will move the cover plate 202, and the cover plate 202 will stretch the spring rod Ⅲ 201, so that the spring rod Ⅲ 201 will buffer the pulling force and reduce the impact of external pulling force on the cable interface 12.

[0044] Those skilled in the art should understand that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by equivalent substitution or equivalent transformation fall within the protection scope of the present invention.
