[0036] Combine the following Figure 1-Figure 8 The liquid crystal display screen module of the present invention is described.

[0037] like Figure 1-Figure 8 As shown, in one embodiment, a liquid crystal display screen module includes:

[0038] An outer frame 100, a bottom frame 110 is provided at the bottom of the outer frame 100, a first connection frame 140 is fixedly connected to the inner side of the outer frame 100, a display screen body 120 is provided between the first connection frame 140 and the inner wall of the outer frame 100, a second connection frame 150 is fixedly connected to the inner side of the bottom frame 110, and a backlight module 130 is provided inside the second connection frame 150;

[0039] A limiting assembly 200, wherein the limiting assembly 200 is disposed inside the first connecting frame 140;

[0040] A connection component 210, which is disposed inside the second connection frame 150, and is used to cooperate with the limiting component 200 to achieve connection limiting between the outer frame 100 and the bottom frame 110;

[0041] Among them, the connecting component 210 includes two heat conducting plates 2101 which are respectively embedded and installed on the inner side of the second connecting frame 150 and are symmetrically distributed. The other side of the heat conducting plate 2101 is fixedly connected with evenly distributed heat dissipating fins 2102. The bottom of the bottom frame 110 is provided with two symmetrically distributed grooves 160, and the other end of the heat dissipating fin 2102 extends to the interior of the groove 160.

[0042] By setting up the heat dissipation fins 2102 and the heat conducting plate 2101, the heat generated during the operation of the backlight module 130 can be absorbed, and the heat can be dissipated through the heat dissipation fins 2102 by connecting with the outside world through the grooves 160, thereby reducing the influence of heat accumulation inside on the use of the backlight module 130, and avoiding the influence of long-term heat on the limiting component 200 and the connecting component 210.

[0043] like Figure 1-Figure 6 As shown, the connecting component 210 also includes a plurality of connecting blocks 2104 fixedly connected to the top of the second connecting frame 150 and evenly distributed, and a clamping block 2105 is fixedly connected to the top of the connecting block 2104, and the cross-sectional shape of the clamping block 2105 is a right-angled trapezoid, and the clamping block 2105 and the connecting block 2104 are both plastic components.

[0044] A thermally conductive strip 2108 is embedded in the top of the second connecting frame 150, and a uniformly distributed support plate 2106 is fixedly connected to the top of the thermally conductive strip 2108. The other end of the support plate 2106 passes through the connecting block 2104 and the clamping block 2105 in sequence and is fixedly connected to a bending plate 2109. The cross-sectional shape of the bending plate 2109 is V-shaped. The bottom of the thermally conductive strip 2108 is fixedly connected to a uniformly distributed thermally conductive rod 2103, and the other end of the thermally conductive rod 2103 extends to the inside of the groove 160.

[0045] The other end of the bending plate 2109 is fixedly connected to a connecting portion, and the other end of the connecting portion is fixedly connected to an adsorption block 2110 .

[0046] A mounting block 2111 is provided on the inner side of the bending plate 2109, and the mounting block 2111 is fixedly connected to the inner wall of the clamping block 2105. The cross-sectional shape of the mounting block 2111 is L-shaped. A support rod 2107 is fixedly connected to the inner side of the mounting block 2111, and the other end of the support rod 2107 is fixedly connected to the inner wall of the bending plate 2109.

[0047] The bending plate 2109 and the supporting plate 2106 are both made of aluminum metal materials, and the adsorption block 2110 is made of iron metal materials.

[0048] By pressing the card block 2105, the connecting block 2104 connected thereto can bend, and after the pressure is released, it can be restored by its own elastic force under the action of the plastic material component. The thermal conductive strip 2108, the bending plate 2109, the thermal conductive rod 2103 and the support plate 2106 are all aluminum metal components, which can have a good thermal conductivity effect. Together with the thermal conductive rod 2103, the heat can be dissipated through the groove 160, thereby reducing the situation where the card block 2105 and the connecting block 2104 absorb heat for a long time, causing the material to become brittle and affect the limiting effect of the limiting component 200.

[0049] The arrangement of the bending plate 2109, the support plate 2106, the support rod 2107 and the mounting block 2111 can strengthen the strength of the clamping block 2105 and the connecting block 2104, reduce thermal deformation, and provide support points when deformation occurs, so that a good clamping effect can be maintained after thermal deformation, thereby avoiding the possibility of falling off and loosening due to a decrease in the clamping effect due to thermal deformation.

[0050] like Figure 7 and Figure 8 As shown, the limiting assembly 200 includes two installation grooves which are respectively opened on the inner side of the first connecting frame 140 and symmetrically distributed, the inner wall of the installation groove is slidably connected with a push plate 2004, the bottom of the push plate 2004 is opened with a card slot 2005, and a limiting groove for limiting the card block 2105 is formed between the inside of the card slot 2005 and the installation groove.

[0051] The other side of the push plate 2004 is fixedly connected with a uniformly distributed connecting rod 2001, the other end of the connecting rod 2001 passes through the first connecting frame 140 and the outer frame 100 in sequence and is fixedly connected with an adjustment plate 2003, the surface of the connecting rod 2001 is fixedly connected with a spring 2002, and the other end of the spring 2002 is fixedly connected to the inner wall of the outer frame 100.

[0052] A connecting strip 2006 is provided inside the push plate 2004, and one side of the connecting strip 2006 is fixedly connected to magnets 2007 that are evenly distributed and correspond to the adsorption block 2110, and the other side of the connecting strip 2006 is fixedly connected to a mounting rod 2009 that is evenly distributed and slidably connected to the inner wall of the connecting rod 2001.

[0053] Two symmetrically distributed positioning rods 2008 are fixedly connected to the surface of the mounting rod 2009 , and the other ends of the positioning rods 2008 pass through the connecting rod 2001 and are fixedly connected to the inner wall of the first connecting frame 140 .

[0054] The outer frame 100 and the bottom frame 110 are aligned and then spliced. During this process, the first connecting frame 140 and the second connecting frame 150 can be aligned with each other. At the same time, the inner edge of the first connecting frame 140 is used to squeeze the inclined surface of the block 2105 to deform it until it moves to the installation groove and can be reset under the elastic force of the block 2105 and the connecting block 2104. During this process, the block 2105 can be inserted into the limiting groove and limited by the inner wall of the limiting groove to prevent the bottom frame 110 and the outer frame 100 from separating.

[0055] At the same time, after being installed in place, the magnet 2107 can generate suction force on the adsorption block 2110 of the ferrous metal material component, thereby strengthening the limiting effect to avoid deviation, and after being deformed by heat, the suction force can be used to maintain the position of the connecting part, the bending plate 2109, the adsorption block 2110, the installation block 2111 and the support rod 2107, so that the installation block 2111 can maintain a good limiting effect to avoid falling off;

[0056] During disassembly, pushing the adjustment plate 2003 can drive the connecting rod 2001 to move synchronously, so that it drives the push plate 2004 to push the block 2105 to deform and separate from the limit groove. In this process, the spring 2002 can be squeezed, and the position of the magnet 2007 remains unchanged due to the restriction of the installation rod 2009 and the positioning rod 2008, thereby preventing the block 2105 from always being close to the push plate 2004.

[0057] Working principle: Align the outer frame 100 and the bottom frame 110 and then splice them. During this process, the first connecting frame 140 and the second connecting frame 150 can be aligned with each other, and at the same time, the inner edge of the first connecting frame 140 is used to squeeze the inclined surface of the card block 2105 to deform it, until it moves to the installation groove and can be reset under the elastic force of the card block 2105 and the connecting block 2104. During this process, the card block 2105 can be inserted into the inside of the limiting groove, and the inner wall of the limiting groove is used to limit it to prevent the bottom frame 110 and the outer frame 100 from separating. After being installed in place, the magnet 2007 can generate suction on the adsorption block 2110 of the ferrous metal material component, thereby strengthening the limiting effect and avoiding deviation, and after being deformed by heat, the suction can be used to maintain the position of the connecting part, the bending plate 2109, the adsorption block 2110, the installation block 2111 and the support rod 2107. The mounting block 2111 can be used to maintain a good limiting effect to prevent it from falling off. During disassembly, the adjusting plate 2003 can be pushed to drive the connecting rod 2001 to move synchronously so that it drives the push plate 2004 to push the block 2105 to deform and separate from the limiting groove. In this process, the spring 2002 can be squeezed, and the position of the magnet 2007 restricted by the mounting rod 2009 and the positioning rod 2008 remains unchanged, thereby preventing the block 2105 from always being close to the push plate 2004. During use, the heat dissipation fin plate 2102 and the heat conduction plate 2101 can be set to absorb the heat generated during the operation of the backlight module 130, and the groove 160 is used to connect with the outside world and dissipate it through the heat dissipation fin plate 2102, thereby reducing the heat accumulation inside and affecting the use of the backlight module 130, and at the same time, it can avoid the influence of long-term heat on the limiting component 200 and the connecting component 210.

[0058] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0059] The above-described embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
